The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. In order to simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present disclosure provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

Next, with reference to the drawings, a virtual wall device 200 for a floor sweeping robot 100 according to an embodiment of the first aspect of the present invention is described.

As shown in fig. 1, the virtual wall device 200 for the sweeping robot 100 according to the first aspect of the present invention may include: the casing 1, the movement 2, and the mechanical switch 3, with reference to fig. 2, the casing 1 may include a first end wall 111 and a second end wall 121 that are oppositely disposed in a first direction F1, and a peripheral wall 13 connected between the first end wall 111 and the second end wall 121, the peripheral wall 13 having a first light-transmitting area a and a second light-transmitting area B that are sequentially arranged in a direction from the first end wall 111 to the second end wall 121, the casing 1 being reversible between a normal state in which the first end wall 111 is positioned above the second end wall 121 and an inverted state in which the second end wall 121 is positioned above the first end wall 111 with reference to fig. 3.

As shown in fig. 2, when the housing 1 is in the upright position, the first end wall 111 is located above the second end wall 121, and the first light-transmitting area a is located above the second light-transmitting area B, and referring to fig. 3, when the housing 1 is turned to the inverted position, the second end wall 121 is located above the first end wall 111, and the second light-transmitting area B is located above the first light-transmitting area a.

As shown in fig. 2 and 3, the movement 2 is provided in the housing 1 relatively stationary with respect to the housing 1, i.e., the movement 2 is immovable with respect to the housing 1 to turn synchronously with the housing 1 when the housing 1 turns, and the movement 2 may include a first emitter 21 and a second emitter 22, and the virtual wall apparatus 200 is provided such that the first emitter 21 is adapted to emit a first signal line toward a multi-angle through a first light-transmitting area a, and the second emitter 22 is adapted to emit a second signal line toward a single angle through a second light-transmitting area B.

For example, in one embodiment, the first transmitter 21 is operated to set the virtual wall apparatus 200 in an omnidirectional transmitting state, which can be used to establish an arc-shaped virtual isolation area (shown as a dashed area in fig. 6), and the second transmitter 22 is operated to set the virtual wall apparatus 200 in a linear transmitting state, which can be used to establish a linear virtual isolation area (shown as a dashed area in fig. 7), so that the virtual wall apparatus 200 can have two operating modes. It should be noted that the types of the first emitter 21 and the second emitter 22 are not limited, and may include, but are not limited to, infrared sensors, which are known to those skilled in the art and will not be described herein. It should be noted that the virtual isolation area that can be established by the virtual wall device 200 may be specifically set according to the arrangement form of the light-transmitting area and the selection type of the emitter, and is not limited herein.

In the embodiment of the present invention, the mechanical switch 3 is movable relative to the housing 1 and configured to move relative to the housing 1 (for example, slide relative to the housing 1, rotate relative to the housing 1, etc.) under the action of gravity in the process of turning the housing 1, and when the housing 1 is turned to the front state (as shown in fig. 2 and fig. 4), the first signal line can be emitted out of the housing 1, so that the second signal line cannot be emitted out of the housing 1, and when the housing 1 is turned to the upside down state (as shown in fig. 3 and fig. 5), the second signal line can be emitted out of the housing 1, so that the first signal line cannot be emitted out of the housing 1. That is, when the housing 1 is turned over, the mechanical switch 3 is mechanically moved relative to the housing 1 by gravity, for example, slides relative to the housing 1, rotates relative to the housing 1, and so on, whereby the virtual isolation area formed by the virtual wall apparatus 200 can be switched by the movement of the mechanical switch 3 relative to the housing 1.

For example, when the virtual wall device 200 is turned to the upright position, as shown in fig. 2, the first light-transmitting area a is located above the second light-transmitting area B, the first emitter 21 emits a multi-angle signal outwards through the first light-transmitting area a, so that the virtual wall device 200 is switched to the operation mode of the arc-shaped virtual isolation area (as shown in fig. 6 by the dotted line), and when the virtual wall device 200 is turned to the upside down, as shown in fig. 3, the second light-transmitting area B is located above the first light-transmitting area a, and the second emitter 22 emits a single-angle signal outwards through the second light-transmitting area B, so that the virtual wall device 200 is switched to the operation mode of the linear-shaped virtual isolation area (as shown in fig. 7 by the dotted line).

Therefore, when the virtual wall device 200 is used, a user only needs to turn over the virtual wall device 200, operation is convenient, the possibility of misoperation is reduced, in addition, the mechanical switching piece 3 is switched relative to the shell 1 through mechanical movement under the action of gravity, complex circuit control is omitted, the problem of circuit faults existing in the circuit control is solved, the switching reliability of the virtual wall device 200 for switching the working modes is high, and the cost of the virtual wall device 200 is low.

According to the utility model discloses a virtual wall device 200 for sweeping floor robot 100 of first aspect embodiment can accomplish the switching of mode automatically through upset virtual wall device 200, and the mode switches the reliability higher, user convenient to use.

In some embodiments, as shown in fig. 2, mechanical switch 3 may include: the shielding member 31 is movable relative to the housing 1 along a first direction F1, when the housing 1 is turned to a forward position, the shielding member 31 avoids the first light-transmitting area a and shields the second light-transmitting area B, and as shown in fig. 3, when the housing 1 is turned to an upside-down position, the shielding member 31 avoids the second light-transmitting area B and shields the first light-transmitting area a.

That is, when the housing 1 is turned to the right position, as shown in fig. 2, the shielding member 31 moves along the first direction F1 to the position for shielding the second light-transmitting area B under the action of gravity, and the first light-transmitting area a is exposed, at this time, the second signal line emitted by the second emitter 22 is shielded by the shielding member 31, and the first signal line emitted by the first emitter 21 is emitted from the first light-transmitting area a, so that only the signal of the virtual isolation area in the multi-angle direction can be formed outside the housing 1, and the signal of the virtual isolation area in the single direction cannot be formed.

On the contrary, as shown in fig. 3, when the housing 1 is turned upside down, the shielding member 31 moves along the first direction F1 to the position for shielding the first light-transmitting area a under the action of gravity, and the second light-transmitting area B is exposed, at this time, the first signal line emitted by the first emitter 21 is shielded by the shielding member 31, and the second signal line emitted by the second emitter 22 is emitted from the second light-transmitting area B, so that only the signal of the virtual isolation area in a single direction can be formed outside the housing 1, and the signal of the virtual isolation area in multiple angle directions cannot be formed, and therefore, the mechanical switch member 3 has a simple structure and high operational reliability.

In some embodiments, as shown in fig. 2, the shielding member 31 is located in the housing 1 and sleeved outside the movement 2, so that the housing 1 can protect the shielding member 31, and the shielding member 31 has a simple structure and is easy to install. Alternatively, in some other embodiments, the shielding member 31 may be located outside the housing 1 and sleeved on the housing 1 (this example is not shown). This simplifies the structure of the shutter 31 and provides flexibility.

In some embodiments, as shown in fig. 2 and 3, the housing 1 may have a limiting structure 14 thereon, and the limiting structure 14 is used for limiting the movement range of the shutter 31 along the first direction F1, so as to improve the operational reliability of the shutter 31, and meanwhile, the limiting structure 14 has a simple structure and is convenient to arrange. For example, in the example shown in fig. 2 and 3, the limiting structure 14 may be a rib provided on the inner wall of the housing 1 and the first end wall 111.

In some embodiments, as shown in fig. 2, the housing 1 may include: the transparent cover 11 is a cylinder with one open end in the axial direction and comprises a first end wall 111 and a first sub-peripheral wall 112, the shell body 12 is a cylinder with one open end in the axial direction and comprises a second end wall 121 and a second sub-peripheral wall 122, the transparent cover 11 is abutted with the shell body 12 along a first direction F1, so that the first sub-peripheral wall 112 and the second sub-peripheral wall 122 are abutted to form the peripheral wall 13, wherein the first sub-peripheral wall 112 serves as a first light transmission area A, and part of the second sub-peripheral wall 122 transmits light to serve as a second light transmission area B.

That is, the first sub-peripheral wall 112 is entirely used as the first light-transmitting area a, so that the first light-transmitting area a is the entire circumferential area, so as to realize the multi-angle emission of the first signal line, and a part of the second sub-peripheral wall 122 is used as the second light-transmitting area B, so that the second light-transmitting area B is the partial area, so as to realize the single-angle emission of the second signal line. Moreover, the user can easily observe the difference between the first light transmission area a and the second light transmission area B when using the virtual wall device 200, so that the user can correctly use the required mode only by placing (rightly placing or inverting) according to the own requirements in the process of using the virtual wall device 200, and the possibility of misoperation is reduced.

Of course, the present invention is not limited to this, for example, different marks may be set on the outer surfaces of the first end wall 111 and the second end wall 121 to distinguish the working modes, etc., so as to directly prompt the user what working mode is currently used, which is not described herein.

It should be noted that the specific type of the "cylinder" is not limited, for example, the cylinder may be a cylinder, a polygonal cylinder, etc., and the manufacturing materials of the first light-transmitting area a and the second light-transmitting area B are not limited, for example, the first light-transmitting area a and the second light-transmitting area B may include but are not limited to transparent plastic, as long as the first signal line and the second signal line can be well emitted from the first light-transmitting area a and the second light-transmitting area B to a use environment (for example, indoors), which is not described herein again.

In some embodiments, as shown in fig. 1, the second end wall 121 is removably connected to the second sub-perimeter wall 122 to facilitate removal. For example, the user may open the second end wall 121 and perform an operation such as maintenance or replacement of the internal components (e.g., replacement of the power supply member 24 described later). It should be noted that the specific form of the detachable connection is not limited, and for example, the detachable connection may be achieved by a snap fit connection, a threaded connection, and the like, which are not described herein again.

In some embodiments, as shown in fig. 2, the movement 2 may further include a mounting bracket 23, the first emitter 21 is disposed on a side of the mounting bracket 23 facing the first end wall 111, the second emitter 22 is disposed on a side of the mounting bracket 23 facing the peripheral wall 13, an inner side of the first end wall 111 has a reflection structure 1111, and the reflection structure 1111 is adapted to reflect the signal line emitted by the first emitter 21 to the first light-transmitting area a, so that the first signal line is emitted along multiple angles.

That is, the first emitter 21 and the second emitter 22 are both mounted on the mounting frame 23, and the first emitter 21 and the second emitter 22 can emit signal lines in different directions, for example, when the housing 1 is in the upright position, as shown in fig. 2, the first signal line emitted from the first emitter 21 is firstly emitted to the reflective structure 1111 on the inner side of the first end wall 111, at this time, the reflection of the first signal line by the reflective structure 1111 can change the direction, the first signal line is reflected into multi-angle signal lines by the reflective structure 1111, and then these reflected first signal lines can enter the working environment through the first light-transmitting area a in multiple angles (combined with the dashed area shown in fig. 6), when the housing 1 is turned to the upside-down position, as shown in fig. 3, the single-direction signal emitted from the second emitter 22 can directly enter the working environment through the second light-transmitting area B (combined with the dashed area shown in fig. 7), thereby, the structure of the virtual wall device 200 is made simple.

It should be noted that, the specific form of the reflective structure 1111 is not limited, for example, in the specific example shown in fig. 2, the reflective structure 1111 is a cone protruding from the first end wall 111 toward the second end wall 121, so that the reflective structure 1111 is simple and easy to machine, for example, the reflective structure 1111 may be formed together with the transparent cover 11, and be a single piece, for example, the reflective structure 1111 and the transparent cover 11 may also be formed separately and then assembled, for example, the reflective structure 1111 may be adhered to the first wall end by a method such as a double-sided adhesive, etc., which will not be described herein again.

In some embodiments of the present invention, when mechanical switch 3 includes shielding 31, as shown in fig. 2, movement 2 may further include power supply part 24, and power supply part 24 is always electrically connected to first emitter 21 and second emitter 22. That is, the first transmitter 21 and the second transmitter 22 operate simultaneously and are both supplied with power from the power supply part 24. It should be noted that the type of the power supply component 24 is not limited, and for example, the power supply component may be a battery or a circuit board, and in addition, when the power supply component 24 is a battery, the type of the battery is also not limited, and for example, the battery may be a rechargeable battery, a dry battery, and the like, and details thereof are not described herein.

In other embodiments of the present invention, when the movement 2 includes the power supply part 24, the power supply part 24 may not be electrically connected to the first and second transmitters 21 and 22 all the time. For example, as shown in fig. 4 and 5, the mechanical switch 3 may include: the rotating member 32, the rotating member 32 is rotatable about the pivot shaft 322 relative to the housing 1, and the rotating member 32 may include a power connection terminal 321 electrically connected to the power supply unit 24, as shown in fig. 4, when the housing 1 is turned to the upright position, the power connection terminal 321 is electrically connected to the power connection point 211 of the first transmitter 21 and is electrically disconnected from the power connection point 221 of the second transmitter 22, and as shown in fig. 5, when the housing 1 is turned to the upside down position, the power connection terminal 321 is electrically connected to the power connection point 221 of the second transmitter 22 and is electrically disconnected from the power connection point 211 of the first transmitter 21.

Thus, regardless of whether the mechanical switch 3 includes the shutter 31, the switching action of the dotted line region can be achieved by turning over the virtual wall apparatus 200. More specifically, since the mechanical switch 3 includes the above-mentioned rotating member 32, the rotating member 32 can switch one of the first transmitter 21 and the second transmitter 22 to be operated and the other to be not operated by the turning of the housing 1, thereby reducing power consumption of the virtual wall apparatus 200, for example, when the virtual wall apparatus 200 is powered by a battery, the standby time of the virtual wall apparatus 200 can be increased. Furthermore, it should be noted that, in the embodiment of the present disclosure, the mechanical switch 3 may include both the rotating part 32 and the shielding part 31, and the mechanical switch 3 may further include only one of the rotating part 32 and the shielding part 31.

For example, when the housing 1 is turned upside down, the power connection point 211 of the first transmitter 21 and the power connection point 221 of the second transmitter 22 are stationary with respect to the housing 1 (i.e., when the housing 1 is turned upside down, the power connection point 211 of the first transmitter 21 and the power connection point 221 of the second transmitter 22 are turned along with the housing 1), and at the same time, during the process of turning the housing 1 from the front position (as shown in fig. 4) to the upside down (as shown in fig. 5), the rotating member 32 rotates with respect to the housing 1 around the pivot axis 322 (i.e., the rotating member 32 does not turn along with the turning of the housing 1, but rotates with respect to the housing 1 under the. Therefore, the user can select to turn the virtual wall device 200 to the positive state or the negative state, so that the virtual wall device 200 can automatically complete the switching of the working modes, and the use by the user is facilitated. It should be noted that the specific shape of the rotating member 32 is not limited, and for example, the rotating member may be rectangular, cylindrical, conical, etc., which are not described herein.

As shown in fig. 4 to 5, in order to improve the operation stability and the operation reliability of the rotating member 32, the rotating member 32 may further include an insulation weight terminal 323, as shown in fig. 4, when the housing 1 is turned to the front position, the electrical connection terminal 321 is electrically connected to the electrical connection point 211 of the first transmitter 21, and the insulation weight terminal 323 is electrically disconnected from the electrical connection point 221 of the second transmitter 22, as shown in fig. 5, when the housing 1 is turned to the upside down position, the electrical connection terminal 321 is electrically connected to the electrical connection point 221 of the second transmitter 22, and the insulation weight terminal 323 is electrically disconnected from the electrical connection point 211 of the first transmitter 21. Therefore, in the process of turning the housing 1 between the upright state and the inverted state, the insulation counterweight end 323 can be always positioned at the lower side relative to the power receiving end 321 under the action of gravity, thereby improving the working stability and the working reliability of the rotating member 32.

Furthermore, in some embodiments, the power receiving terminal 321 may be made of an electrically conductive material with elastic deformation, so that the connection effectiveness when the power receiving terminal 321 is electrically connected to the power receiving point 211 of the first transmitter 21 and the power receiving point 221 of the second transmitter 22 can be further improved, and when the rotating member 32 rotates relative to the housing 1, the power receiving terminal 321 can be smoothly separated from the power receiving point 211 of the first transmitter 21 and the power receiving point 221 of the second transmitter 22, thereby improving the operational reliability of the rotating member 32, but the present invention is not limited thereto.

In the following, with reference to the accompanying drawings, specific examples of two different forms of mechanical switch 3 are described, it being noted that the following two specific examples are intended to illustrate the present invention and are not to be construed as limiting the present invention.

Example 1

As shown in fig. 2 and 3, the mechanical switch 3 includes a shielding member 31, the power supply member 24 is electrically connected to the first emitter 21 and the second emitter 22, when the virtual wall device 200 is placed, the shielding member 31 moves to shield the first signal line emitted from the first emitter 21, the virtual wall device 200 is in an omnidirectional emission state, an arc-shaped virtual isolation area can be formed outside the virtual wall device 200, and conversely, when the virtual wall device 200 is placed upside down, the shielding member 31 moves to shield the second signal line emitted from the second emitter 22, and a straight-shaped virtual isolation area can be formed outside the virtual wall device 200.

Example two

As shown in fig. 4 and 5, the mechanical switch 3 includes a rotating member 32 and does not include a shielding member 31, the rotating member 32 includes an electrical terminal 321 electrically connected to the power supply member 24, when the virtual wall device 200 is placed upright, the electrical terminal 321 is rotated to be electrically connected to the electrical terminal 211 of the first transmitter 21, the first signal line emitted from the first transmitter 21 is emitted from the first light-transmitting area a without being shielded, and an arc-shaped virtual isolation area may be formed outside the virtual wall device 200, whereas when the virtual wall device 200 is placed upside down, the electrical terminal 321 is rotated to be electrically connected to the electrical terminal 221 of the second transmitter 22, and the second signal line emitted from the second transmitter 22 is emitted from the second light-transmitting area B without being shielded, and a straight-shaped virtual isolation area may be formed outside the virtual wall device 200.

In summary of the above two specific examples, the user can automatically complete the switching of the operation mode of the virtual wall device 200 by the mechanical movement of the mechanical conversion part relative to the housing 1 during the process of placing the virtual wall device 200 upright or upside down. From this, virtual wall device 200's setting is nimble and convenient to use, as long as the user normally places according to own needs and can correctly use, can not have the frequent switch button of using, leads to the wrong problem of state switching. In addition, compared with the virtual wall device in the related art, the problem that the user uses the virtual wall device 200 in a wrong way without knowing the switch state can be solved.

Next, a sweeping robot assembly 1000 according to an embodiment of the second aspect of the present invention will be described with reference to the drawings.
