Detailed ways

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The pedal device according to the first embodiment is an accelerator pedal device mounted on an automobile or the like, and as shown in FIGS. The vibrating unit U of the electric motor 40 , the sleeve 50 , the bolt 61 and the nut 62 , the sliding plate 70 , the biasing spring 80 , the return spring 90 , and a position sensor for detecting the rotational angle position of the pedal arm 20 .

The position sensor is composed of an armature and a yoke embedded in the pedal arm 20 , and a stator and a hall element embedded in the case 10 .

The case 10 is formed of a resin material, and is composed of a first case 11 and a second case 12 that are connected to each other and define a swing axis S. As shown in FIG.

The first case 11 accommodates the slider 70 , the urging spring 80 , and the return spring 90 in a state where the pedal arm 20 is swingably incorporated around the swing axis S.

The second case 12 is provided with a connector 12a electrically connected to the Hall element of the built-in position sensor.

In the state where the pedal arm 20 , the slider 70 , the biasing spring 80 and the return spring 90 are mounted on the first cover 11 , the second cover 12 cooperates with the first cover 11 to cover all but the pedal arm 20 . The integral way of the lower area is connected to the first casing 11 by snap-fit and fastened by screws.

The whole pedal arm 20 is formed of a resin material, and functions as a resin part as a whole, and is provided with a cylindrical portion 21 as a supported portion, an upper arm 22 extending upward from the cylindrical portion 21, and an upper arm 22 extending from the cylindrical portion 21 to A lower arm 23 extending downward, and an accelerator pedal 24 serving as an operating pedal.

The accelerator pedal 24 is integrally formed with the pedal arm 20 .

Here, the upper side and the lower side mean the upper side and the lower side in the vertical direction in a state where the accelerator pedal device is mounted on a vehicle or the like.

The cylindrical portion 21 is swingably supported about the swing axis S by the support portion of the case 10 .

The upper arm 22 has an abutment portion 22a abutting against the inner wall of the case 10 at the rest position, a contact portion 22b detachably in contact with the slider 70 , and a spring receiving portion 22c for receiving the end of the return spring 90 .

The lower arm 23 has, in the vicinity of the cylindrical portion 21, a contact portion 23a that contacts the cover 10 at the maximum depression position, and a cylindrical through hole 23b centered on an axis L parallel to the swing axis S. .

The through hole 23 b is formed so as to extend in the axis L direction in an area exposed to the outside of the pedal arm 20 in a state of being assembled in the case 10 .

In addition, the lower arm 23 has one side portion 23c on which the casing 30 of the vibrating unit U abuts and the other side portion 23d on which the head of the bolt 61 abuts, at both ends of the through hole 23b.

One side portion 23c is formed in a concave shape and has an inner wall surface 23c1 having two parallel surfaces for non-rotatably fitting fitting cylindrical portion 31c of the casing 30 and an annular abutting surface 23c2. The surface 23c2 is brought into contact with the front end surface 31c1 of the fitting cylinder portion 31c.

The other side portion 23d protrudes annularly in the direction of the axis L around the through hole 23b, and forms a seat surface on which the head of the bolt 61 abuts.

The vibrating unit U is composed of a casing 30 and an electric motor 40 .

The case 30 is formed of a resin material, and is composed of a case body 31 and a case cover 32 detachably connected to the case body 31 .

The housing body 31 includes a recess 31a, a nut fitting portion 31b, a fitting cylinder 31c, a connector 31d, a buckling protrusion 31e, an incorporated terminal 31f, and openings 31g and 31h.

The concave portion 31 a is formed to house the electric motor 40 , and is formed to define an opening 31 g that opens vertically downward or obliquely downward in a state attached to the pedal arm 20 .

The nut fitting part 31b is formed so that the opening part 31h adjacent to the opening part 31g may be divided, and the nut 62 may be fixedly positioned and fitted.

In addition, the nut fitting portion 31b forms a seating surface on which the nut 62 abuts in the axis L direction.

The fitting cylindrical portion 31 c is formed in a cylindrical shape having two parallel surfaces, and a part of the sleeve 50 is fitted inside, and is formed so as to fit and abut against the concave side portion 23 c of the pedal arm 20 .

That is, by fitting the outer peripheral wall of the fitting cylindrical portion 31c into the inner wall surface 23c1 of the one side portion 23c, the vibrating unit U is positioned at a predetermined angular position around the axis L with respect to the pedal arm 20 .

In addition, the vibrating unit U is positioned at a predetermined position in the axis L direction with respect to the pedal arm 20 by bringing the front end surface 31c1 of the fitting tube portion 31c into contact with the annular contact surface 23c2 of the one side portion 23c.

The connector 31d accommodates the terminal 31f for electrical connection, and extends toward the axis S within the swing range (rest position to maximum depression position) of the pedal arm 20 in a state where the vibrating unit U is fixed to the pedal arm 20 . Long way configuration.

Accordingly, when the pedal device is mounted on a vehicle or the like, the wiring on the vehicle body side is connected to the connector 31d. Here, when the pedal arm 20 moves between the rest position and the maximum depression position, the connector 31d is always oriented toward the axis S, so that the amount of displacement of the wiring on the vehicle body side can be reduced.

Therefore, it is possible to prevent interference with other components, wear, or disconnection of the wiring due to movement of the wiring.

The case cover 32 includes a recessed portion 32 a for snapping and a rectangular ring-shaped fitting portion 32 b that fits into the recessed portion 31 a of the case body 31 .

In addition, the case cover 32 is connected to the case body 31 by snap-fitting so as to close the openings 31g and 31h of the case body 31 in a state where the electric motor 40 and the nut 62 are housed in the case body 31 .

The electric motor 40 includes a motor body 41 to which an elastic member 41 a is attached, a rotating shaft 42 having an axis M, and an eccentric mass body 43 fixed to the rotating shaft 42 .

The elastic member 41 a is formed in a cylindrical shape from an elastic material such as silicone rubber having a predetermined thickness, and is attached so as to surround the outer periphery of the motor body 41 .

In addition, the electric motor 40 is fixed in the housing 30 while compressing the elastic member 41a from four sides by fitting the motor body 41 into the recess 31a of the housing body 31 and closing it while being pressed by the housing cover 32 .

In addition, by starting the electric motor 40 , the eccentric mass body 43 rotates integrally with the rotation shaft 42 , thereby generating vibration. The generated vibration is transmitted to the pedal arm 20 and the accelerator pedal 24 via the housing 30 .

Thus, since the electric motor 40 is held in the housing 30 via the elastic member 41a, it is possible to prevent or suppress generation of a gap between the electric motor 40 and the housing 30 due to a change over time.

Therefore, the vibration generated by the electric motor 40 can be efficiently transmitted from the housing 30 to the pedal arm 20 without being lost in the form of sound energy such as rattling.

Here, in the state where the vibrating unit U is attached to the pedal arm 20 , the rotation shaft 42 (axis M) of the electric motor 40 is oriented so as to extend in a direction other than parallel to the swing axis S. As shown in FIG.

That is, by arranging the rotation shaft 42 of the electric motor 40 and the swing axis S of the pedal arm 20 in a twisted direction, the vibration direction by the eccentric mass body 43 does not coincide with the swing direction of the pedal arm 20 .

Accordingly, it is possible to prevent adverse effects on the operation of the pedal arm 20 , to draw attention to the vibration generated in a direction different from the swing direction, and to ensure desired operability.

The sleeve 50 is formed in a cylindrical shape from a metal material, and the bolt 61 is passed through the inside thereof. In addition, the bolt 61 and the nut 62 are also made of metal.

Here, the sleeve 50 is fitted so as to be passed through the through hole 23 b of the pedal arm 20 and the fitting cylindrical portion 31 c of the housing 30 , and is assembled so that the one end portion 51 can abut against the nut 62 .

As described above, the pedal arm 20 is formed of a resin material and the metal sleeve 50 is fitted into the through-hole 23b extending parallel to the swing axis S, and the vibration unit is connected by the bolt 61 passing through the sleeve 50 . U fastened.

Therefore, the weight reduction and moldability of the pedal arm 20 can be improved, and the vibrating unit U can be firmly fixed to the pedal arm 20 , so that the vibration generated by the electric motor 40 can be reliably transmitted to the pedal arm 20 .

In particular, as shown in FIG. 5 , the sleeve 50 is set to be longer than the seating surface of the nut 62 of the nut fitting portion 31 b to the seating surface of the bolt 61 of the pedal arm 20 (the other side portion 23 d ). The dimension W is shorter than the dimension H by a predetermined amount (H<W).

Thereby, by making the one end part 51 of the sleeve 50 contact the nut 62 fitted in the nut fitting part 31b of the housing 30, the rigidity of a connection area|region can be improved. Furthermore, by tightening the pedal arm 20 while being compressed in the direction of the axis L until the head of the bolt 61 abuts against the other end portion 52 of the sleeve 50, the rigidity of the connecting region can be further increased.

Therefore, the vibration generated by the vibrating unit U can be efficiently transmitted to the pedal arm 20 without being attenuated by the connection region.

In the above-described structure, a part of the sleeve 50 is fitted into the fitting cylindrical portion 31c of the housing 30, and the fitting cylindrical portion 31c is fitted and abutted against the one side portion 23c of the pedal arm 20. The bolt 61 is inserted into the sleeve 50 in the one side portion 23d, and the nut 62 fitted in the nut fitting portion 31b is screwed into the nut fitting portion 31b, so that the assembly work can be easily performed and the connection rigidity between the housing 30 and the pedal arm 20 can be improved.

In addition, in the above-mentioned structure, the casing 30 includes: a casing body 31, which divides an opening 31g and an opening 31h that open vertically or obliquely downward, and accommodates the electric motor 40; and a casing cover 32 that is connected to the casing body 31. Since the opening 31g and the opening 31h are closed, the electric motor 40 is covered by the case cover 32 while being inserted into the case body 31 from the lower side in the vertical direction when the pedal device is mounted on a vehicle or the like.

Therefore, even if liquid such as drinking water is spilled by an operator or the like, the liquid can be prevented from penetrating into the casing 30 and desired functions can be ensured.

The sliding sheet 70 is formed of a highly slidable material such as oil-containing polyacetal, and is disposed so as to be slidable on the inner wall of the case 10 .

The urging spring 80 is a compression type coil spring (coil spring), and is arranged between the inner wall of the case 10 and the sliding piece 70 in a compressed state.

In addition, the slider 70, the contact portion 22b of the pedal arm 20, and the urging spring 80 constitute a hysteresis generating mechanism that generates hysteresis in the pedaling force.

The return spring 90 is a compression-type coil spring, and is arranged in a compressed state between the inner wall of the case 10 and the spring receiving portion 22 c of the pedal arm 20 .

In addition, the return spring 90 directly applies force to the pedal arm 20 so as to return the pedal arm 20 to the rest position.

According to the pedal device having the above structure, the vibrating unit U is connected to the lower arm 23 on the lower side of the cylindrical portion 21 centered on the swing axis S and is exposed from the case 10 and close to the case 10 . In the region of the lower arm 23 , it is attached to the pedal arm 20 .

That is, since the vibrating unit U is attached to the pedal arm 20 in the vicinity of the swing axis S, long wiring as conventionally is unnecessary.

In addition, there is no uncomfortable feeling in operation that is worrying when the electric motor is provided on the back side of the accelerator pedal as in the past. Therefore, it is possible to provide a function of attracting attention by vibration, and to ensure required operability.

In addition, the vibrating unit U includes an electric motor 40 provided with an eccentric mass body 43 on a rotating shaft 42 , a casing 30 accommodating the electric motor 40 and fixed to the pedal arm 20 , and a connection protruding from the casing 30 to electrically connect the electric motor 40 . Therefore, by fixing the housing 30 housing the electric motor 40 to the pedal arm 20, the pedal device incorporating the vibrating unit U can be easily provided.

In particular, the vibrating unit U can be modularized so that it can be applied to various pedal devices. For example, when the specification of the pedal arm 20 differs for each vehicle type, by changing only the pedal arm 20 , parts such as the cover 10 and the vibrating unit U can be shared, thereby achieving cost reduction and the like.

Furthermore, since the vibrating unit U is attached to the lower arm 23 in the vicinity of the cylindrical portion 21 of the pedal arm 20 , the moment of inertia of the pedal arm 20 around the swing axis S can be kept small. Thereby, operability of the pedal arm 20 can be ensured, and a desired function of attracting attention by vibration can be ensured.

Next, the operation of the accelerator pedal device will be described with reference to FIGS. 7 and 8 .

First, when the accelerator pedal 24 is not depressed by the driver, the pedal arm 20 stops at the rest position due to the biasing force of the return spring 90 and the urging spring 80 as shown in FIG. 7 .

At this time, the connector 31d of the vibrating unit U extends toward the direction of the swing axis S. As shown in FIG.

When the driver depresses the accelerator pedal 24 from this state, the pedal arm 20 rotates clockwise against the urging force of the return spring 90 and the urging spring 80 , as shown in FIG. 8 , rotates to the maximum depressing position and stops.

At this time, the connector 31d of the vibrating unit U extends toward the direction of the swing axis S. As shown in FIG.

That is, the connector 31d is arranged so as to extend toward the swing axis S within the swing range (rest position to maximum depression position) of the pedal arm 20. In this state, the pedal arm 20 swings, and the amount of displacement of the wiring can also be reduced. Therefore, it is possible to prevent interference with other components, wear, or disconnection of the wiring due to movement of the wiring.

In addition, when the control means on the vehicle side determines that the driving mode calls for the driver's attention, the electric motor 40 of the vibrating unit U is rotated by a predetermined control signal to generate vibration. Then, the generated vibration is transmitted from the housing 30 to the pedal arm 20 and the accelerator pedal 24 .

The driver's attention is attracted by the transmission of the vibration, so that the operation of returning the accelerator pedal 24 is performed.

According to the accelerator pedal device having the above structure, since the vibrating unit U is attached to the pedal arm 20 in the vicinity of the swing axis S, it is possible to avoid the uncomfortable feeling in operation that is worrying when it is installed on the back side of the accelerator pedal as in the past. It has the function of attracting attention by vibration and ensures the required operability.

In addition, the rotation shaft 42 of the electric motor 40 included in the vibrating unit U is oriented in a direction other than parallel to the swing axis S. As shown in FIG. Here, the axis M is positioned at a position twisted at right angles with respect to the swing axis S. As shown in FIG.

According to this arrangement, as shown in FIG. 9 , the vibration becomes larger in the left-right direction (the direction of the rocking axis S) of the accelerator pedal device, while the vibration becomes smaller in the rocking direction of the pedal arm 20 .

That is, by orienting the rotation shaft 42 of the electric motor 40 and the rocking axis S of the pedal arm 20 in a twisted direction, the vibration direction by the eccentric mass body 43 and the rocking direction of the pedal arm 20 are not aligned. Accordingly, adverse effects on the operation of the pedal arm 20 can be prevented.

As a result, desired operability is ensured, and the driver's attention is attracted by the vibration generated in a direction different from the shaking direction.

This mounted state is an example, and the present invention does not exclude the arrangement in which the connector 31d is oriented in a direction away from the swing axis S. As shown in FIG.

The connector 31d can be oriented in a preferred direction by appropriately changing the installation angle of the vibrating unit U in a layout in which interference or the like does not occur.

For example, it is preferable to fix the vibrating unit U to the pedal arm 120 so that the connector 31 d extends toward the swing axis S within the swing range of the pedal arm 120 , as in the first embodiment described above.

Sliding piece 171 is made of a highly slidable material such as oil-impregnated polyacetal, and has an inclined surface 171a in contact with inclined surface 172b of sliding piece 172 and an abutting portion 171b abutting against abutting pin 122a of pedal arm 120 .

The slider 172 is formed of a high-slidability material such as oil-containing polyacetal, and has an inclined surface 172 a that contacts the inclined surface 171 a of the slider 171 .

In addition, the sliding piece 171 and the sliding piece 172 are disposed so as to be slidable on the inner wall of the case 100 in a state where the inclined surface 171 a and the inclined surface 172 a are in contact.

The urging spring 181 is a compression-type coil spring, and is arranged between the inner wall of the housing 100 and the sliding piece 171 in a compressed state.

The urging spring 182 is a compression type coil spring, and is arranged between the inner wall of the housing 100 and the sliding piece 172 in a compressed state.

The slide plate 171 , the slide plate 172 , the urging spring 181 , and the urging spring 182 constitute a hysteresis generating mechanism that generates hysteresis in the pedaling force.

The return spring 190 is a torsion coil spring, and is disposed around the swing axis S such that one end 191 is held by the holding portion 121b of the pedal arm 120 and the other end is held by a part of the housing 100 .

In addition, the return spring 190 directly applies force to the pedal arm 120 so as to return the pedal arm 20 to the rest position.

According to the accelerator pedal device of the second embodiment, the vibrating unit U is exposed from the cover 100 in the region of the thin plate portion 123 of the lower arm connected to the lower side of the circular plate portion 121 centered on the swing axis S. And it is attached to the pedal arm 120 in a region close to the thin plate portion 123 of the lower arm of the case 100 .

That is, since the vibrating unit U is attached to the pedal arm 120 in the vicinity of the swing axis S, long wiring as conventional is unnecessary.

In addition, there is no uncomfortable feeling in operation that is worrying when the electric motor is provided on the back side of the accelerator pedal as in the past. Therefore, it is possible to provide a function of attracting attention by vibration, and to ensure required operability.

In addition, the rotation shaft 42 of the electric motor 40 included in the vibrating unit U is positioned in a direction other than parallel to the swing axis S. As shown in FIG. That is, it is positioned at a position twisted at a right angle with respect to the swing axis S.

In this way, by orienting the rotation shaft 42 of the electric motor 40 and the swing axis S of the pedal arm 120 in the twisted direction, the vibration direction by the eccentric mass body 43 and the swing direction of the pedal arm 120 are not aligned.

Accordingly, adverse effects on the operation of the pedal arm 120 can be prevented. As a result, desired operability is ensured, and the driver's attention is attracted by the vibration generated in a direction different from the shaking direction.

In particular, the vibrating unit U is directly fixed to the metal thin plate portion 123a serving as the lower arm, so that the vibrating unit U can be firmly secured without using the sleeve 50 as shown in the above-mentioned first embodiment. fixed to the pedal arm 120.

In the second embodiment, a case where a part of the lower arm of the pedal arm 120 is formed by the metal rod portion 124 is shown, but the present invention is not limited to this, and instead of the rod portion 124, the whole may be made of a thin plate-shaped metal. The material is integrally formed into the lower side arms.

In addition, although the case where all the pedal arms 120 are formed of a metal material was shown, it is not limited to this.

For example, it is also possible to adopt a pedal arm formed of a resin material and a metal material by adopting the following structure: in the pedal arm, a supported portion centered on the swing axis S, an upper arm, and a lower arm connected to the supported portion. A part of the side arm is formed of a resin material as a resin part, and a metal rod member is fitted and bonded to a part of the lower side arm as a metal part, or a metal plate-like member is used as a metal part.
