Description

Motorized drive device for a masking device, and related masking device

Technical Field

The invention relates to a motorized drive device for a screening device, in other words, to a motorized drive device for a screening device, wherein the motorized drive device is arranged or configured to move at least one barrier.

The invention also relates to a screening device equipped with the motorized drive device.

The present invention generally relates to the field of screening devices. The screening device comprises a motorized drive device. The motorized drive device moves a barrier between at least one first position and at least one second position.

Background Art

The known document WO2020/099628A1 records a motorized drive device for a masking device. The motorized drive device includes a housing, a drive module, and an electronic control unit. The housing includes a cavity and an opening. The electronic control unit includes a printed circuit board and an electrical connection device. In the combined structure of the motorized drive device, the electrical connection device can be reached through the opening of the housing. The electrical connection device includes an electrical connection point. The electrical connection point is arranged on one side of the printed circuit board. Further, the motorized drive device includes a switch device. The switch device is configured to close the opening of the housing. The switch device is removable relative to the housing. In addition, the document WO2020/099628A1 records that after the switch device is removed relative to the housing, the plug of the terminal can be positioned at the opening of the housing of the motorized drive device, so that the electrical connection point of the electrical connection device is arranged to be electrically connected to the electrical connection pin of the plug of the terminal. The motorized drive device is generally satisfactory.

However, this motorized drive has the disadvantage that the switch device is mounted on the housing opposite to the opening of the housing and that after the switch device is removed, the plug of the terminal is also mounted in the place of the switch device.

Therefore, the electrical plug of the terminal is not configured to be accommodated in the cavity of the housing to replace any component of the motorized drive device, because after removing the switching device by disassembling the fixing element, the electrical connection device can only be reached from outside the housing through the housing opening by positioning the plug of the terminal against the housing.

Furthermore, the electrical connection pins are fixed relative to the plug of the terminal, in other words, are not movable relative to the plug of the terminal.

Therefore, the electrical connection pins cannot be moved relative to the terminal plug by the mechanism integrated in the plug so as to contact the electrical connection points of the electrical connection device arranged on one side of the printed circuit board, which itself is arranged in the housing of the motorized drive device.

Therefore, when the electrical connection pins of the plug of the terminal and/or the electrical connection points of the electrical connection device come into contact with each other, they may be damaged due to the pressure exerted by the electrical connection pins on the electrical connection points.

Summary of the invention

The object of the present invention is to solve the above-mentioned shortcomings and to propose a motorized drive device for a masking device, and a masking device comprising such a motorized drive device, which are capable of facilitating and ensuring electrical contact between the electrical connection pins of the connection module and the electrical connection points of the printed circuit board of the electronic control unit of the motorized drive device, while limiting the risk of damage to the electrical connection pins and the electrical connection points.

When the complementary member is accommodated in the cavity of the housing, each first fastening element of the complementary member is configured to cooperate with one of the second fastening elements of the housing so as to keep the complementary member in position in the housing. The connection module further comprises a third fastening element. When the connection module is accommodated in the cavity of the housing instead of the complementary member, each third fastening element of the connection module is configured to cooperate with one of the second fastening elements of the housing so as to keep the connection module in position in the housing.

According to another advantageous feature of the present invention, the supplementary component comprises a plurality of first electrical connection elements, each of which comprises a first electrical contact area.

Advantageously, the housing 43 comprises at least one first recess 8. The first recess 8 is configured to receive a first portion of the first suspension element 7; in other words, the first recess 8 receives a first portion of the first suspension element 7, in particular in a combined configuration of the motorized drive device 10.

Here, without limitation, the first groove 8 is realized by a cutout left in each of the first half-shell 43 a and the second half-shell 43 b .

In the example of the figures, the first groove 8 comprises a first opening and a second opening. The first groove 8 opens simultaneously into the upper surface 9c of the wall 9 in the form of a hole (especially a circular hole) forming the first opening and into the peripheral contour 43c in the form of a cutout forming the second opening.

Advantageously, the manipulating element 46 comprises a recess 46a with a non-circular cross section for receiving the first portion 7a with a non-circular cross section of the first suspension element 7. This enables the first suspension element 7 and the manipulating element 46 to rotate integrally about the axis of rotation X7.

Advantageously, in the unlocked state, the first suspension element 7 is detachable relative to the first recess 8 of the housing 43 .

Thus, in the unlocked state, the first suspension element 7 can be removed from the first recess 8 of the housing 43 by moving in the direction of the rotation axis X7 .

In addition, the first half shell and the second half shell are configured to be assembled together by a fixing element (not shown), in other words, the first half shell and the second half shell are assembled together by a fixing element, especially in the combined structure of the drive unit 49.

The fixing element of the cover 50 may be, for example, a screw-fixing element.

There is no restriction on the type of the fixing elements of the first half shell and the second half shell of the cover, and they can be of different types. For example, the fixing elements can be elastic buckle fixing elements.

Advantageously, the drive wheel 13 is configured to be partially placed inside the cover 50 of the drive unit 49 and to be partially placed outside the cover 50 of the drive unit 49, in other words, the drive wheel 13 is partially placed inside the cover 50 of the drive unit 49 and the drive wheel 13 is partially placed outside the cover 50 of the drive unit 49, in particular in the combined structure of the motorized drive device 10, more specifically, in the combined structure of the drive unit 49.

Advantageously, the or each elastic return element 44 is configured to cooperate with the housing 43 on the one hand and with the cover 50 on the other hand; in other words, the or each elastic return element 44 cooperates with the housing 43 on the one hand and with the cover 50 on the other hand, in particular in the combined structure of the motorized drive device 10. Furthermore, the drive wheel 13 is configured to bear against the first surface 5 of the rod 4 by means of the or each elastic return element 44; in other words, the drive wheel 13 bears against the first surface 5 of the rod 4 by means of the or each elastic return element 44, in particular in the state in which the motorized drive device 10 is mounted on the rod 4.

In this way, the drive module 49 can be moved inside the housing 43 under the action of the elastic return element 44, in particular according to a translational movement M, so that the drive wheel 13 abuts against the first surface 5 of the rod 4, in particular in the combined configuration of the screening device 3. This corresponds to the translational movement M described above.

Here, the elastic return element 44 is configured to cooperate with a first supporting wall 52 arranged in the housing 43 of the motor drive device 10 on the one hand, and to cooperate with a cover 50 of the drive module 49 on the other hand; in other words, the elastic return element 44 cooperates with a first supporting wall 52 arranged in the housing 43 of the motor drive device 10 on the one hand, and to cooperate with the cover 50 of the drive module 49 on the other hand.

Advantageously, the first supporting wall 52 is parallel to the rod 4 , in particular in the assembled configuration of the screening device 3 .

Here, without limitation, the first supporting wall 52 is realized by a portion left in each of the first half shell 43 a and the second half shell 43 b of the housing 43 .

In the combined structure of the masking device 3, during the movement of the motorized drive device 10 along the rod 4 through the electrical activation of the motor 11, for the closing and opening of the barrier 2, the elastic return element 44 can take into account the overall changes of the barrier 2 pulled or pushed by the motorized drive device 10 and adjust the pressure applied by the drive wheel 13 on the rod 4.

Advantageously, when the electric motor 11 is electrically activated, the cover 50 is configured to be tilted inside the housing 43 relative to the median plane P of the housing 43 ; in other words, the cover 50 is tilted inside the housing 43 relative to the median plane P of the housing 43 .

In the combined structure of the masking device 3, when the motor 11 is electrically activated, the drive wheel 13 rests against the rod 4 through the elastic return element 44, and the elastic return element 44 rests against the first supporting wall 52 located in the shell 43. The drive wheel 13 is driven to rotate around the first rotation axis X13 by the motor 11 (and possibly also through the transmission device 28).

In this way, a compressive force is exerted on the elastic return element 44 so that the drive module 49 moves in the housing 43. The movement of the drive module 49 in the housing 43 depends on the direction of rotation of the electric motor 11 and thus of the drive wheel 13.

In this way, the drive module 49 is in an inclined position inside the housing 43 and, more specifically, the drive module 49 is in an inclined position relative to the rod 4 .

As a result, a camber is produced in the motorized drive device 10 , so that the force of the drive wheel 13 on the rod 4 increases, so that the motorized drive device 10 moves along the rod 4 .

Advantageously, when the electric motor 11 is electrically deactivated, the drive module 49 can be in a position such that its median plane is parallel to the median plane P of the housing 43 , indeed it overlaps with the median plane P.

As a variant (not shown), when the electric motor 11 is electrically deactivated, the drive module 49 can remain in a position inclined relative to the mid-plane P of the housing 43, in particular due to the force of the drive wheel 13 on the first surface 5 of the rod 4, in particular in the combined structure of the masking device 3, and after the motorized drive device 10 has been moved along the rod 4.

In the assembled configuration of the screening device 3 , when the motor 11 is electrically deactivated, the drive wheel 13 rests on the rod 4 via the elastic return element 44 which rests on the housing 43 and more specifically on the first bearing wall 52 .

In this way, a force is applied in a balanced manner to the elastic return element 44. This force is transmitted to the housing 43 and the wall 9, and then to the first and second retaining means 37, 39, which then transmit the force to the rod 4.

In this way, the drive module 49 can be in a vertical position inside the housing 43 and, more specifically, in a vertical position relative to the rod 4 assuming that the rod 4 is horizontal.

Advantageously, the shell 43 is configured to maintain a predetermined orientation relative to the rod 4 by means of the first retaining device 37 and the second retaining device 39; in other words, the shell 43 maintains a predetermined orientation relative to the rod 4 by means of the first retaining device 37 and the second retaining device 39, and in particular remains unchanged over time, in particular in the combined structure of the masking device 3.

In this way, this predetermined orientation of the housing 43 relative to the rod 4 is achieved by holding the motorized drive device 10 on the rod 4 by the first retaining means 37 and the second retaining means 39 cooperating with the rod 4, both during electrical deactivation of the motor 11 and during electrical activation of the motor 11.

In this way, the angle value (not shown) between the middle plane P of the housing 43 and the longitudinal axis A4 of the rod 4 is constant, whether when the motorized drive device 10 is stopped relative to the rod 4 or when the motorized drive device 10 is moved along the rod 4 by electrical activation of the motor 11.

Preferably, the angle between the median plane P of the housing 43 and the longitudinal axis A4 of the rod 4 has a value of 90°.

This configuration of the motorized drive device 10 makes it possible to minimize the stiffness value of the or each elastic restoring element 44 .

Since the motorized drive device 10 is held in position relative to the rod 4 by the first and second holding means 37 , 39 , the stiffness value of the elastic return element 44 determines the initial contact pressure of the drive wheel 13 on the rod 4 when the electric motor 11 is electrically deactivated.

The power supply module 40 and the electrical connection device 57 of the motorized drive device 10 shown in FIGS. 1 to 7 , as well as the connection module 61 which also belongs to the motorized drive device 10 , are described in more detail here with reference to FIGS. 3 to 11 .

In this case, the motorized drive 10 also comprises a connecting module 61 .

The connection module 61 includes a frame 63 .

Here, the frame 63 of the connection module 61 has a shape substantially similar to that of the power module 40 .

The connection module 61 further includes a first electrical connection pin 62 .

The connection module 61 further includes a moving mechanism 67. In addition, the moving mechanism 67 is configured to move the first electrical connection pin 62 of the connection module 61 between the retracted position and the extended position, and between the extended position and the retracted position relative to the frame 63; in other words, the moving mechanism 67 moves the first electrical connection pin 62 of the connection module 61 between the retracted position and the extended position, and between the extended position and the retracted position relative to the frame 63.

The moving mechanism 67 may also be referred to as an extension-retraction mechanism or a projection-withdrawal mechanism. The retracted position may also be referred to as a withdrawn position. Further, the extended position may also be an extended position or a projection position.

When the connection module 61 is accommodated in the cavity 14 of the housing 43, the movement of the first electrical connection pin 62 between the retracted position and the extended position realizes the electrical connection between the electrical connection point 60 and the first electrical connection pin 62 in the extended position. In other words, when the connection module 61 is accommodated in the cavity 14 of the housing 43, the electrical connection point 60 of the electrical connection device 57 is configured to be electrically connected to the first electrical connection pin 62 of the connection module 61 in the extended position; in other words, the electrical connection point 60 of the electrical connection device 57 is electrically connected to the first electrical connection pin 62 of the connection module 61 in the extended position.

The electronic control unit 17 further comprises an electrical connection device 57 . The electrical connection device 57 is accessible through the first opening 42 of the housing 43 ; in other words, the electrical connection device 57 is configured to be accessible through the first opening 42 of the housing 43 , in particular in the assembled structure of the motorized drive device 10 .

The electrical connection device 57 at least includes an electrical connection point 60. The electrical connection point 60 is disposed on one side 26A of the printed circuit board 26.

The cavity 14 of the housing 43 is configured to selectively accommodate the power module 40; in other words, the cavity 14 of the housing 43 selectively accommodates the power module 40. The power module 40 is therefore accommodated inside the cavity 14 of the housing 43. After the power module 40 is removed relative to the housing 43 through the first opening 42 of the housing 43, the connection module 61 is accommodated inside the cavity of the housing 43 to replace the power module 40, so that the electrical connection point 60 of the electrical connection device 57 is configured to be electrically connected to the first electrical connection pin 62 of the connection module 61 in the extended position of the first electrical connection pin 62 relative to the frame 63.

It can be understood that the cavity 14 of the shell 43 is configured to accommodate the power module 40 without the connection module 61 as described above, or to accommodate the connection module 61 instead of the power module 40 as described above. In other words, the cavity 14 of the shell 43 accommodates the power module 40 without the connection module 61 as described above, or to accommodate the connection module 61 instead of the power module 40 as described above, especially in the combined structure of the motor drive device 10.

Therefore, this structure of the motorized drive device 10 makes it convenient and ensures that after the power module 40 is replaced by the connection module 61 in the housing 43 of the motorized drive device 10 (in particular, it is not necessary to disassemble the motorized drive device 10 relative to the shielding device 3), the first electrical connection pin 62 of the connection module 61 and the electrical connection point 60 of the electrical connection device 57 of the electronic control unit 17 of the motorized drive device 10 are in electrical contact, while limiting the risk of damage to the electrical connection pin 62 and the electrical connection point 60.

In this way, during maintenance or repair interventions on the motorized drive 10 , the connection module 61 is accommodated in the cavity 14 of the housing 43 instead of the power module 40 in order to reach the electrical connections 57 of the electronic control unit 17 of the motorized drive 10 via the connection module 61 .

Therefore, after the power module 40 is removed from the cavity 14 of the shell 43, since the power module 40 no longer closes the first opening 42 of the shell 43, the connection module 61 is electrically connected to the electrical connection device 57 of the electronic control unit 17 of the motor drive device 10 by inserting the connection module 61 into the first opening 42 set in the shell 43 of the motor drive device 10 and then moving the first electrical connection pin 62 between the retracted position and the extended position.

Furthermore, when the connection module 61 is inserted into or removed from the cavity 14 of the housing 43 , the moving mechanism 67 can avoid damaging the first electrical connection pins 62 and the electrical connection points 60 .

Furthermore, placing the connection module 61 in the cavity 14 of the housing 43 instead of the power module 40 makes it possible to omit positioning and/or fixing elements arranged in the housing 43 except for elements for assembling the power module 40 with the housing 43 .

Advantageously, as shown in FIG. 8 , the connection module 61 is configured to be connected to the terminal 68 via a link L. In other words, the connection module 61 is connected to the terminal 68 via a link L.

The terminal 68 may be, for example, a configuration tool, a local control unit 15 or a central control unit 16. The terminal 68 may also be a smartphone, a tablet or a computer.

Here, the link L between the connection module 61 and the terminal 68 is realized by a first line 69 and a second line 81. The first line 69 is configured to allow communication between the terminal 68 and the connection module 61, preferably bidirectional communication. In addition, the second line 81 is configured to supply power from the terminal 68 to the connection module 61.

Therefore, after the terminal 68 is electrically connected to the connection module 61 through the first line 69, and the connection module 61 is electrically connected to the electrical connection device 57 through the first electrical connection pin 62 and the electrical connection point 60, the terminal 68 is configured to communicate with the electronic control unit 17 of the motorized drive device 10 through the connection module 61.

In this way, the communication between the electronic control unit 17 of the motorized drive device 10 , the connection module 61 and the terminal 68 is achieved in a wired manner.

Furthermore, after the terminal 68 is electrically connected to the connection module 61 through the second line 81 , the terminal 68 is configured to supply power to the connection module 61 .

Advantageously, after the terminal 68 is electrically connected to the connection module 61 via the first line 81, and the connection module 61 is electrically connected to the electrical connection device 57 via the first electrical connection pin 62 and the electrical connection point 60, the terminal 68 is configured to supply power to the electronic control unit 17 of the motor drive device 10 via the connection module 61.

As a variant (not shown), the link L between the connection module 61 and the terminal 68 is realized by a single line. This single line is configured to allow communication between the terminal 68 and the connection module 61, preferably in a bidirectional manner, and is optionally configured to supply power from the terminal 68 to the connection module 61 and optionally to the electronic control unit 17 of the motorized drive device 10.

As a variant (not shown), the link L between the connection module 61 and the terminal 68 is realized by signal exchange, in particular radio or optical signal exchange. Further, the connection module 61 and the terminal 68 respectively include a communication module for transmitting and/or receiving signals. The signal exchange can be realized according to a communication protocol, which can be, for example, Wifi, Bluetooth or a proprietary protocol. Therefore, after the terminal 68 is paired with the connection module 61 and the connection module 61 is electrically connected to the electrical connection device 57 through the first electrical connection pin 62 and the electrical connection point 60, the terminal 68 is configured to communicate with the electronic control unit 17 of the motorized drive device 10 through the connection module 61. In this way, the communication between the electronic control unit 17 of the motorized drive device 10 and the connection module 61 is realized in a wired manner, and the communication between the connection module 61 and the terminal 68 is realized in a wireless manner.

Advantageously, the electrical connection device 57 is configured, through the connection module 61 and by means of the terminal 68 , to reset or adjust at least some of the operating parameters of the motorized drive 10 , which are stored by a memory of the microcontroller 18 of the electronic control unit 17 .

Here, the operating parameter may be, for example, the moving speed of the shading object 2 or the high stroke end position or the low stroke end position of the shading object 2 .

Advantageously, the electrical connection means 57 are configured to allow diagnosis of the motorized drive 10 via the terminal 68 and by means of the connection module 61 , based on operating data of the motorized drive 10 stored by a memory of the microcontroller 18 of the electronic control unit 17 .

The operating data may be, for example, the temperature of the motor drive 10 which can be measured by a temperature probe (not shown), the number of operating cycles of the motor drive 10 within a predetermined period of time or the current consumption within a predetermined period of time.

Advantageously, the electrical connection point 60 is an electrical conductor.

In this case, the electrical conductors of the first printed circuit board 26 correspond to the electrical tracks printed on the first printed circuit board 26 .

In this case, the electrical connection device 57 comprises 14 electrical connection points 60 .

There is no limitation on the number of electrical connection points, which can be different numbers. In particular, the number of electrical connection points can be greater than or equal to 2.

Advantageously, the electrical connection point 60 is electrically connected to a port of the microcontroller 18 of the electronic control unit 17 by means of electrical traces (not shown) printed on the first printed circuit board 26 .

In this case, the home automation device 1 comprises a masking device 3 , a motorized drive 10 and a terminal 68 .

Advantageously, the connection module 61 comprises at least one second printed circuit board 82. The second printed circuit board 82 is placed inside the frame 63. Furthermore, the first electrical connection pins 62 are fixed to the second printed circuit board 82.

Advantageously, the first electrical connection pin 62 is electrically connected to the first line 69 via an electrical trace printed on a second printed circuit board 82 (not shown).

Advantageously, the connection module 61 further comprises a handle 70. Further, the moving mechanism 67 is configured to move the first electrical connection pin 62 of the connection module 61 relative to the frame 63 by actuating the handle 70; in other words, the moving mechanism 67 moves the first electrical connection pin 62 of the connection module 61 relative to the frame 63 by actuating the handle 70.

Advantageously, after the connection module 61 is inserted into the cavity 14 of the housing 43 , the pull handle 70 is actuated so as to bring the first electrical connection pin 62 of the connection module 61 into contact with the electrical connection point 60 of the electrical connection device 57 .

Advantageously, the handle 70 is accessible from the outside of the frame 63 and from the outside of the housing 43 after the connection module 61 has been inserted into the cavity 14 of the housing 43 .

Advantageously, the moving mechanism 67 includes at least one first inclined surface 71. The pull handle 70 includes at least one second inclined surface 72. In addition, when the first electrical connection pin 62 moves between the retracted position and the extended position and between the extended position and the retracted position relative to the frame 63, the first inclined surface 71 abuts against the second inclined surface 72.

Therefore, after the connecting module 61 is inserted into the cavity 14 of the shell 43, the first bevel 71 and the second bevel 72 cause the first electrical connecting pin 62 to move from the retracted position to the extended position relative to the frame 63; and before the connecting module 61 is taken out of the cavity 14 of the shell 43, the first bevel 71 and the second bevel 72 cause the first electrical connecting pin 62 to move from the extended position to the retracted position relative to the frame 63.

Advantageously, the connecting module 61 is inserted into or removed from the cavity 14 of the housing 43 along a movement direction Y of the connecting module 61 in the cavity 14 of the housing 43 .

Here, the first bevel 71 and the second bevel 72 are inclined relative to the movement direction Y of the connecting module 61 in the cavity 14 of the housing 43 .

Advantageously, along the direction of movement Y of the connection module 61 in the cavity 14 of the housing 43, the first inclined surface 71 is preceded by a first planar region 85 and followed by a second planar region 86. The first inclined surface 71 has a first end 71a and a second end 71b, and the second end 71b is opposite to the first end 71a. The first planar region 85 is arranged at the first end 71a of the first inclined surface 71, and the second planar region 86 is arranged at the second end 71b of the first inclined surface 71. Along the direction of movement Y of the connection module 61 in the cavity 14 of the housing 43, the second inclined surface 72 is preceded by a third planar region 87 and followed by a fourth planar region 88. The second inclined surface 72 has a first end 72a and a second end 72b, and the second end 72b is opposite to the first end 72a. The third planar region 87 is arranged at the first end 72a of the second inclined surface 72, and the fourth planar region 88 is arranged at the second end 72b of the second inclined surface 72. When the first electrical connection pin 62 is in the retracted position relative to the frame 63, the first planar area 85 abuts against the third planar area 87, and the second planar area 86 abuts against the fourth planar area 88. In addition, when the first electrical connection pin 62 is in the extended position relative to the frame 63, the second planar area 86 abuts against the third planar area 87.

In this case, first planar region 85 , second planar region 86 , third planar region 87 and fourth planar region 88 are parallel to movement direction Y of connecting module 61 in cavity 14 of housing 43 .

Here, the first bevel 71 and the second bevel 72 are inclined relative to the movement direction Y of the connecting module 61 in the cavity 14 of the housing 43 .

Advantageously, the frame 63 further comprises at least one first support 74. The pull handle 70 further comprises at least one second support 76. Furthermore, when the first electrical connection pin 62 reaches the retracted position relative to the frame 63, the second support 76 abuts against the first support 74.

Therefore, during the retracting movement of the first electrical connection pin 62 relative to the frame 63 , the movement of the handle 70 within the frame 63 is limited due to the support of the first support post 74 and the second support post 76 .

Advantageously, the connecting module 61 further comprises an elastic return element 77 .

Advantageously, when the first electrical connection pin 62 moves between the retracted position and the extended position relative to the frame 63, in particular when the handle 70 is actuated in a direction opposite to the direction in which the first electrical connection pin 62 moves between the retracted position and the extended position relative to the frame 63, each elastic return element 77 is configured to apply pressure to the frame 63, in other words, each elastic return element 77 applies pressure to the frame 63.

Therefore, the elastic return element 77 can ensure that the first inclined surface 71 of the moving mechanism 67 contacts the second inclined surface 72 of the handle 70, and can ensure that the first electrical connection pin 62 of the connecting module 61 contacts the electrical connection point 60 of the electrical connection device 57, while limiting the value of the force applied to the first electrical connection pin 62 and the electrical connection point 60.

In this case, each elastic restoring element 77 is a spring, in particular a helical spring.

Here, the number of elastic restoring elements 77 is four, of which only three are shown in FIG. 9 and only two are shown in FIG. 10 .

Each of the guide pins 83 is placed in one of the guide holes 84, in other words, each of the guide pins 83 is configured to be placed in one of the guide holes 84, in particular in the combined structure of the connection module 61. In addition, when the first electrical connection pin 62 moves between the retracted position and the extended position and between the extended position and the retracted position relative to the frame 63, the printed circuit board 82 is guided in translation, in other words, the printed circuit board 82 is configured to be guided in translation.

Advantageously, the number of guide pins 83 is equal to the number of guide holes 84 .

Here, in a non-limiting manner, the number of guide pins 83 and guide holes 84 is four, respectively, wherein only one guide pin 83 and one guide hole 84 are shown in FIGS. 9 and 10 .

Advantageously, each elastic return element 77 is held by a guide pin 83, in other words, each elastic return element 77 is configured to be held by a guide pin 83, in particular in the combined structure of the connection module 61. In addition, when the first electrical connection pin 62 moves between the retracted position and the extended position and between the extended position and the retracted position relative to the frame 63, each elastic return element 77 is guided relative to the guide pin 83, in other words, each elastic return element 77 is configured to be guided relative to the guide pin 83.

Advantageously, the number of guide pins 83 is equal to the number of elastic return elements 77 .

Advantageously, when the first electrical connection pin 62 moves between a retracted position and an extended position, and between an extended position and a retracted position relative to the frame 63, a movement direction T of the first electrical connection pin 62 of the connection module 61 relative to the frame 63 is orthogonal to a movement direction Y of the connection module 61 within the cavity 14 of the shell 43.

Here, the movement direction Y of the connection module 61 in the cavity 14 of the shell 43 when the connection module 61 is inserted into or removed from the cavity 14 of the shell 43 is the same as the movement direction of the power module 40 in the cavity 14 of the shell 43 when the power module 40 is inserted into or removed from the cavity 14 of the shell 43.

Advantageously, the first printed circuit board 26 of the electronic control unit 17 extends within the housing 43 parallel to the direction of movement Y of the connecting module 61 within the cavity 14 of the housing 43 .

Thus, the second printed circuit board 82 is positioned within the housing 43 so as to maximize the surface on which the first electrical connection pins 62 are mounted.

Advantageously, the connection module 61 further comprises a third fastening element 78. In addition, when the connection module 61 is accommodated in the cavity 14 of the housing 43 instead of the power module 40, each third fastening element 78 of the connection module 61 is configured to cooperate with one second fastening element 45 of the housing 43; in other words, each third fastening element 78 of the connection module 61 cooperates with one second fastening element 45 of the housing 43 so as to keep the connection module 61 in position in the housing 43.

Therefore, during maintenance or repair interventions on the motorized drive device 10 , the connection module 61 is accommodated in the cavity 14 of the housing 43 instead of the power module 40 and is held in position relative to the housing 43 by the same second fastening element 45 as the housing 43 for holding the power module 40 .

Advantageously, the third fastening elements 78 are identical to the first fastening elements 41 , in particular in shape and number.

Therefore, during maintenance or repair interventions on the motor drive 10 , the connection module 61 is accommodated in the cavity 14 of the housing 43 instead of the power module 40 and is held in position relative to the housing 43 by the same fastening elements as are used to accommodate and retain the power module 40 .

Here, the first fastening element 41 and the third fastening element 78 are elastic buckle fixing elements. Further, the second fastening element 45 of the housing 43 is a second opening.

Advantageously, the power module 40 comprises a plurality of first electrical connection elements 54a, 54b. Each of the first electrical connection elements 54a, 54b comprises a first electrical contact region 55. The electronic control unit 17 comprises a plurality of second electrical connection elements 56a, 56b, 56c. Each of the second electrical connection elements 56a, 56b, 56c comprises another electrical contact region 42. In addition, when the power module 40 is accommodated inside the cavity 14 of the housing 43, each of the first electrical contact regions 55 of the first electrical connection elements 54a, 54b is in electrical contact with one of the other electrical contact regions 79 of the second electrical connection elements 56a, 56b, 56c, in other words, each of the first electrical contact regions 55 of the first electrical connection elements 54a, 54b is configured to be in electrical contact with one of the other electrical contact regions 79 of the second electrical connection elements 56a, 56b, 56c, particularly in the combined structure of the electric drive device 10.

As a variation, each of the other electrical contact areas 79 of the second electrical connection elements 56a, 56b, 56c is electrically contacted with one of the first electrical contact areas 55 of the first electrical connection elements 54a, 54b; in other words, each of the other electrical contact areas 79 of the second electrical connection elements 56a, 56b, 56c is configured to be electrically contacted with one of the first electrical contact areas 55 of the first electrical connection elements 54a, 54b.

Thus, mounting the power module 40 in the cavity 14 of the housing 43 facilitates access to the power source 12 for replacement or charging without having to remove the electric drive device 10 from the rod 4. In particular, when the power module 40 is introduced into the cavity 14 of the housing 43, an electrical connection between the power source 12 and the electronic control unit 17 can be achieved regardless of the orientation of the power module 40 in the cavity 14 of the housing 43.

In addition, removing the power module 40 from the housing 43 and installing the power module 40 into the housing 43 are configured to be accomplished using only one hand of the installer, thereby facilitating these operations and ensuring the safety of the installer, especially when the installer climbs up a ladder to reach the electric drive device 10 mounted on the pole 4, because the installer can grab the ladder with the second hand.

Furthermore, regardless of the insertion direction of the power module 40 into the cavity 14 of the housing 43 , the electrical connection between the first electrical connection elements 54 a , 54 b and the second electrical connection elements 56 a , 56 b , 56 c can be implemented in the same manner.

Therefore, when the power module 40 is installed in the cavity 14 of the housing 43 , the power module 40 is flippable relative to its symmetry plane P1 while ensuring consistency in the electrical connection between the electric power source 12 and the electronic control unit 17 .

In addition, each of the second electrical contact regions 64 of the first electrical connection elements 54a, 54b is in electrical contact with one of the electrical energy storage elements 27; in other words, each of the second electrical contact regions 64 of the first electrical connection elements 54a, 54b is configured to be in electrical contact with one of the electrical energy storage elements 27, particularly in the combined structure of the power module 40.

Advantageously, the connection module 61 further comprises second electrical connection pins 80. In addition, when the connection module 61 is accommodated in the cavity 14 of the housing 43 instead of the power module 40, each of the second electrical connection pins 80 is in electrical contact with one of the other electrical contact areas 79 of the second electrical connection elements 56a, 56b, 56c; in other words, each of the second electrical connection pins 80 is configured to be in electrical contact with one of the other electrical contact areas 79 of the second electrical connection elements 56a, 56b, 56c.

In this way, the sunshade 2 of the screening device 3 is wound onto or unwound around a winding tube, which is driven by a motorized drive device 10 .

In this way, the shade 2 can be moved between a reeled position (in particular a high position) and an unrolled position (in particular a low position), and vice versa.

The sunshade 2 of the screening device 3 is a closure, shelter and/or sun protection screen which is wound and unwound around a winding tube whose inner diameter is greater than the outer diameter of the motorized drive device 10 so that the motorized drive device 10 can be inserted into the winding tube when assembling the screening device 3.

The motorized drive means 10 , in particular of the tubular type, enable the winding tube to be rotated about the axis of rotation X in order to move, in particular to unwind or wind up, the shade 2 of the screening arrangement 3 .

The housing 43 is cylindrical (particularly cylindrical around the rotation axis X), and is open at each of its first end 43a and second end 43b. Preferably, the housing 43 is a tube with a circular cross section, which can be made of a metal material or plastic.

When the motorized drive device 10 is working, the motor 11 and the reducer 29 drive the output shaft 100 to rotate. In addition, the output shaft 100 drives the winding tube to rotate through the connecting element.

Advantageously, the motorized drive device 10 further comprises a brake (not shown), which may be, for example, a spring brake, a cam brake, a magnetic brake or an electromagnetic brake. The brake is configured to brake and/or block the rotation of the output shaft 100 so as to adjust the rotation speed of the winding tube during the movement of the shade 2 and to keep the winding tube locked when the motorized drive device 10 is electrically deactivated. In the combined structure of the motorized drive device 10, the brake is configured to be arranged between the motor 11 and the reducer 29 (i.e. at the output end of the motor 11), or between the electronic control unit 17 and the motor 11 (in other words, at the input end of the motor 11), or between the reducer 29 and the output shaft 100 (in other words, at the output end of the reduction gear 29), or between two reduction stages of the reducer 29.

Advantageously, the reduction gear 29 and possibly the brake are accommodated in the housing 43 , in particular in the combined construction of the motorized drive 10 .

Advantageously, the motorized drive 10 and more particularly the electronic control unit 17 also comprise means (not shown), which may be mechanical or electronic, for detecting obstacles and end of travel during the winding of the blind 2 and during the unwinding of this blind 2. Furthermore, the means for detecting obstacles and end of travel are implemented by the microcontroller 18 of the electronic control unit 17, in particular by an algorithm implemented by this microcontroller 18.

Advantageously, the motorized drive device 10 further comprises a crown gear (not shown). In addition, the crown gear is arranged near the first end 43a of the housing 43; in other words, the crown gear is configured to be arranged near the first end 43a of the housing 43, particularly in the combined structure of the motorized drive device 10.

The winding tube rotates about the axis of rotation X and the housing 43 by being supported by two pivot connections. The first pivot connection is realized by a crown gear at the first end of the winding tube. The crown gear can thus form a bearing. The second pivot connection (not shown) is formed at the second end of the winding tube opposite the first end.

The motorized drive device 10 further comprises a torque support 101, which can also be referred to as an "actuator top" or "fixed point". The torque support 101 constitutes a supplementary component of the motorized drive device 10 of the second embodiment. Thus, for the second embodiment, the supplementary component of the motorized drive device 10 is the torque support 101, while for the first embodiment, the supplementary component of the motorized drive device 10 is the power module 40.

In this case, the torque support 101 is arranged at the first end 43 a of the housing 43 , in particular in the assembled structure of the motorized drive device 10 .

The moment support 101 makes it possible to absorb the forces exerted by the motorized drive 10, in particular the torque exerted by the motorized drive 10 relative to the structure of the building. Advantageously, the moment support 101 is also able to absorb the forces exerted by the winding tube, in particular the weight of the winding tube, the motorized drive 10 and the shelter 2, and ensure that these forces are absorbed by the structure of the building.

The moment support 101 thus allows the motorized drive device 10 to be fixed to a frame (not shown), in particular to the side of a cabinet.

Advantageously, the moment support 101 protrudes at the first end 43a of the housing 43a.

Advantageously, the moment support 101 closes the first end 43 a of the housing 43 ; in other words, the moment support 101 is configured to close the first end 43 a of the housing 43 , in particular in the assembled structure of the motorized drive device 10 .

Furthermore, the moment support 101 may support at least a portion of the electronic control unit 17 .

Advantageously, the moment support 101 is fixed to the housing 43 by means of fixing elements, each of which forms one of the first fastening elements 41 , in particular in the combined configuration of the motorized drive device 10 .

Here, the first fastening element 41 is a removable fixing element in order to be able to separate the moment support 101 relative to the housing 43 .

Here, the first fastening element 41 is a fixing screw, in particular two fixing screws. The housing 43 includes through holes, each of which forms one of the second fastening elements 45 of the housing 43, and there may also be two through holes. The moment support 101 includes screw holes 105, and the number of threaded holes is also two. In addition, each of the first fastening elements 41 is arranged to pass through one of the second fastening elements 45 of the housing 43 and be screwed into one of the threaded holes 105 of the moment support 101.

The type and quantity of the first fastening element, the second fastening element and the threaded hole are not limited, and the type and quantity can be different. For example, it can be a fixing element using an elastic buckle, and the number can be three or more. It can also include a groove embedded in the notch.

Advantageously, the electronic control unit 17 can be powered by a power supply line 103. The power supply line 103 is electrically connected to at least one electrical energy supply source (not shown), which can be, for example, an electrical power supply network, in particular mains power or Power over Ethernet (PoE), and/or a battery, which can be accommodated inside the housing 43 or arranged outside the housing 43, which can be rechargeable, in particular by means of a photovoltaic panel and/or a charger (not shown) or by means of an electrical energy supply network.

The power supply line 103 thus allows the motorized drive device 10 , in particular the electronic control unit 17 and the electric motor 11 , to be supplied with electrical energy from one or more electrical energy supply sources.

Here, as shown in FIG. 12 , the electronic control unit 17 is arranged in the housing 43 , in other words, the electronic control unit 17 is integrated in the housing 43 .

Advantageously, the moment support 101 may include at least one button (not shown). The one or more buttons may be used to adjust the motorized drive device 10 through one or more configuration modes, pair one or more control units 15, 16 with the motorized drive device 10, reset one or more parameters (which may be, for example, the end-of-travel position), reset the paired one or more control units 15, 16, or even control the movement of the sunshade 2.

Advantageously, the moment support 101 may comprise at least one display device (not shown) to allow a visual indication of the operating parameters of the motorized drive device 10. The display device may comprise at least one light source (not shown), in particular a light emitting diode. The light source or light sources are mounted on an electronic board of the electronic control unit 17 and optionally on a transparent or translucent cover and/or light guide to allow the light emitted by the light source or each light source to pass.

Here, the motorized drive device 10 also comprises a counting device 38, which is not shown in FIGS. 12 and 13 . Here, the counting device 38 is configured to cooperate with the electronic control unit 17; in other words, the counting device 38 cooperates with the electronic control unit 17. Furthermore, the counting device 38 and the electronic control unit 17 are configured to determine the position of the sunshade 2, which position can be referred to as the “current” position. The electronic control unit 17 is configured to monitor at least one signal provided by the counting device with a predetermined frequency, in particular as a function of the position of the sunshade 2.

In one embodiment, the counting means 38 are of the magnetic type.

In this case, the counting device 38 may comprise a code wheel and one or more sensors, in particular Hall Effect sensors. The code wheel is connected to one axial end of the rotor of the electric motor 11. Furthermore, the sensor or each sensor is assembled on the first electronic board 26 of the electronic control unit 17.

The counting means 38 are thus able to determine the number of revolutions performed by the rotor of the electric motor 11 .

As a variant (not shown), the counting device 38 may not have a sensor.

As a variant (not shown), the counting device 38 is able to determine the number of revolutions performed by the output shaft 100 .

In another variation, the crown gear includes gear teeth (not shown) on its inner surface, which are configured to cooperate with a pinion (not shown). In other words, the gear teeth cooperate with a pinion (not shown), which is mounted inside the torque support 101, or alternatively, the pinion is mounted inside the housing 43.

In this case, the code wheel is connected to the pinion in particular via a shaft.

Thus, the teeth of the crown wheel are configured to drive the pinion wheel in rotation; in other words, the teeth of the crown wheel drive the pinion wheel in rotation in order to count the number of turns of the winding tube.

In this case, the teeth of the crown wheel and the pinion form part of the counting means 38 .

The counting device 38 also allows the direction of rotation of the winding tube to be determined and/or the end-of-travel position of the shade 2 to be managed.

The type of counting device is not limited and may be of different types, in particular of optical type (eg an encoder equipped with one or more optical sensors) or of time type.

In this second embodiment, the connecting module 61 further comprises a gripping element 102 .

It is thus easier for a user to manipulate the connecting module 61 via the gripping element 102 , in particular when inserting or removing the connecting module 61 relative to the cavity 14 of the housing 43 .

Here, the frame 63 of the connecting module 61 has a different shape than the moment support 101. Furthermore, without taking the gripping element 102 into account, the length L61 of the connecting module 61 is greater than the length L101 of the moment support 101.

Only the first line 69 is shown in Figures 14 to 16. However, the connection L may include a second line 81.

Here, the moving mechanism 67 includes two first inclined surfaces 71, and the pull handle 70 includes two second inclined surfaces 72. In addition, when the first electrical connection pin 62 moves between the retracted position and the extended position and between the extended position and the retracted position relative to the frame 63, one of the first inclined surfaces 71 abuts against one of the second inclined surfaces 72, and the other of the first inclined surfaces 71 abuts against the other of the second inclined surfaces 72.

Here, the frame 63 includes two first pillars 74, and the pull handle 70 includes two second pillars 76. Each second pillar 76 is formed by one of the two second inclined surfaces 72 of the pull handle 70. In addition, when the first electrical connection pin 62 reaches the retracted position relative to the frame 63, one of the second pillars 76 abuts against one of the first pillars 74, and the other of the second pillars 76 abuts against the other of the first pillars 74.

Only two of the four elastic restoring elements 77 are shown in FIGS. 14 to 16 .

In this second embodiment, the frame 63 includes guide posts 104. Each of the elastic return members 77 is held by one of the guide posts 104 on the one hand (in other words, each of the elastic return members 77 is configured to be held by one of the guide posts 104 on the one hand), and abuts against the second printed circuit board 82 on the other hand (in other words, is configured to abut against the second printed circuit board 82), especially in the combined structure of the connection module 61.

Therefore, when the first electrical connection pin 62 moves between the retracted position and the extended position, and between the extended position and the retracted position relative to the frame 63, the first elastic return element 77 is configured to be guided relative to the guide column 104; in other words, the first elastic return element 77 is guided relative to the guide column 104.

Advantageously, the number of guide posts 104 is equal to the number of elastic return elements 77 , in this embodiment equal to four.

In this second embodiment, the third fastening element 78 is different from the first fastening element 41 .

Here, the third fastening member 78 is a retractable ball. In addition, each of the third fastening elements 78 is arranged in a groove (not shown) of the frame 63, and is returned to an initial position by a spring.

14 to 16 of the second embodiment, the second electrical connection pins 80 are not shown. However, as shown in the first embodiment, the connection module 61 may include these second electrical connection pins 80.

As a variation (not shown), when these second electrical connection pins 80 move along the movement direction T, the second electrical connection pins 80 can contact electrical connection points (not shown) provided on the first electronic board 26; this is just like the first electrical connection pins 62 relative to the frame 63 when the first electrical connection pins 62 move between the retracted position and the extended position relative to the frame 63, and between the extended position and the retracted position.

Thanks to any embodiment of the present invention, this structure of the motorized drive device makes it possible to facilitate and ensure electrical contact between the first electrical connection pin of the connecting module and the electrical connection point of the electrical connection device of the electronic control unit of the motorized drive device after the supplementary mechanism is replaced by the connecting module inside the housing of the motorized drive device, while limiting the risk of damage to the electrical connection pin and the electrical connection point.

Various modifications may be made to the embodiments described above without departing from the scope of the invention as defined in the claims.

As a variant (not shown), the motorized drive device 10 comprises a single retaining device 37 , 39 .

As a variant (not shown), in the case where the rod 4 is a slide rail, in particular with an "H"-shaped cross section, the first retaining means 37 and the second retaining means 39 each comprise at least one hook, in particular in the form of a pin. The hook is configured to hook onto the ring 48 of the fastening element 53 of the masking device 3; in other words, the hook hooks onto the ring 48 of the fastening element 53 of the masking device 3 so as to retain the housing 43 on the rod 4.

In another variant (not shown), the hooks of the first retaining means 37 and the second retaining means 39 are only a single part, which can be a "U"-shaped hook, for example. Each of the hooks is therefore formed by a branch of a single part. In this case, each branch of the single part constituting the hook is configured to hook the loop 48 of the fastening element 53 of the screening device 3; in other words, each branch of the single part constituting the hook hooks the loop 48 of the fastening element 53 of the screening device 3 so as to keep the housing 43 suspended on the rod 4.

As a variant (not shown), the rod 4 can for example have a circular cross section interrupted by a cut surface, in particular on its underside. In this case, the cut surface of the rod 4 comprises a groove 65 and forms a first track 5a and a second track 5b of the first surface 5, and a first track 6a and a second track 6b of the second surface 6.

"Driven" means that the first driven wheel or each first driven wheel rotates under the action of the movement of the motorized drive device 10 along the rod 4 and its adhesion to the rod 4, in particular to the second surface 6. Thus, the one or more first driven wheels are thus driven to rotate by the translational movement of the housing 43 along the movement direction D. Thus, the first driven wheel or each first driven wheel allows the motorized drive device 10 to move along the rod 4 by rolling it on the second surface 6 of the rod 4. In one embodiment, the first retaining device 37 comprises two first driven wheels. There is no restriction on the number of first driven wheels, and the number of first driven wheels can be different. For example, the number of first driven wheels can be one or more than or equal to three. Advantageously, the first driven wheel or each first driven wheel is configured to be arranged outside the housing 43; in other words, the first driven wheel or each first driven wheel is arranged outside the housing 43, in particular in the combined structure of the motorized drive device 10. Here, in the combined structure of the masking device 3, and more specifically, in the state in which the motorized drive device 10 is mounted on the rod 4, the drive wheel 13 abuts on the first side of the rod 4, and the first driven wheel or each first driven wheel abuts on the second side of the rod 4.

Advantageously, when the first suspension element 7 is in the position corresponding to the locked state relative to the housing 43, the axis of rotation of the first or each first driven wheel is orthogonal to the direction of movement D of the motorized drive device 10 along the rod 4. Furthermore, when the first suspension element 7 is in the position corresponding to the unlocked state relative to the housing 43, the axis of rotation of the first or each first driven wheel is parallel to the direction of movement D of the motorized drive device 10 along the rod 4. Advantageously, when the first suspension element 7 is in the position corresponding to the locked state relative to the housing 43, the axis of rotation of the first or each first driven wheel is parallel to the first axis of rotation X13 of the drive wheel 13. Furthermore, when the first suspension element 7 is in the position corresponding to the unlocked state relative to the housing 43, the axis of rotation of the first or each first driven wheel is orthogonal to the first axis of rotation X13 of the drive wheel 13. Advantageously, the driving wheel 13 comprises a tread, which is referred to as a first tread. The first driven wheel or each first driven wheel comprises a second tread. Furthermore, the first tread of the driving wheel 13 and the second tread of the driven wheel are configured to contact the first surface 5 and the second surface 6 of the rod 4, respectively; in other words, the first tread of the driving wheel 13 and the second tread of the driven wheel are in contact with the first surface 5 and the second surface 6 of the rod 4, respectively, in particular in the combined structure of the masking device 3. Advantageously, the driving wheel 13 is different from the first driven wheel or each first driven wheel. In particular, the outer diameter of the driving wheel 13 is greater than the outer diameter of the first driven wheel or each first driven wheel. Advantageously, the first driven wheel or each first driven wheel is assembled on the first rod 58, in particular by means of a shaft (not shown). In an embodiment, the shaft passes through, on the one hand, a central opening (not shown) of the first driven wheel or each first driven wheel and, on the other hand, a hole (not shown) provided in the first rod 58. The type of assembly of the first driven wheel or each first driven wheel is not limited, and the types of assembly may be different. For example, the type of assembly can be realized as screwing or elastic snap-fitting. Advantageously, the second retaining means 39 is identical to the first retaining means 37 .

In a variant not shown, the rod 4 can, for example, have a circular cross section, in particular a solid or hollow cross section. In this case, the rod 4 is usually referred to as a round rod or round bar. In addition, the rod 4 does not have a groove 65. In such a case, the first driven wheel or each first driven wheel of the first retaining device 37, and the second driven wheel or each second driven wheel of the second retaining device 39 are configured to abut against the first rolling surface of the rod 4; in other words, the first driven wheel or each first driven wheel of the first retaining device 37, and the second driven wheel or each second driven wheel of the second retaining device 39 abut against the first rolling surface of the rod 4. The drive wheel 13 is configured to abut against the second rolling surface of the rod 4; in other words, the drive wheel 13 abuts against the second rolling surface of the rod 4. In addition, the first rolling surface of the rod 4 is located on the upper side of the rod 4, and the second rolling surface of the rod 4 is located on the lower side of the rod 4.

As a variant (not shown), the barrier 2 does not have the suspension element 7, in particular when the rod 4 has a circular cross section, which can be interrupted by a cut surface. In this case, the barrier 2 comprises eyelets. Furthermore, the rod 4 is inserted through the eyelets of the barrier 2, so that the barrier 2 is hung on the rod 4.

As a variant (not shown), the wall 9 also comprises at least one coupling element, and more particularly two coupling elements. Furthermore, the coupling element or each coupling element is configured to receive one of the hooks 75, in other words, the coupling element or each coupling element receives one of the hooks 75, on the one hand to suspend the barrier 2 relative to the rod 4, more particularly relative to the fastening element 53, and on the other hand to drive the barrier 2 to move while the motorized drive 10 moves relative to the rod 4, when the motorized drive 10 is electrically activated or when the motorized drive 10 is manually activated. The coupling element or each coupling element is realized in the form of a hook.
