Description

The present invention relates to a vehicle switch used in a vehicle, and a kickdown switch used in a vehicle accelerator pedal.

2. Description of the Related Art Conventionally, in vehicles such as automobiles, pedal switches such as kick-down switches that detect the depression state of an accelerator pedal are known (for example, Patent Document 1). The kick-down switch described above detects strong depression of the accelerator pedal and downshifts the transmission, thereby smoothly accelerating the vehicle. Furthermore, recently, pedal switches have also been used to suppress false start of vehicles, and there is an increasing demand for them to be retrofitted to vehicles.

Japanese Patent Application Publication No. 2013-4187

By the way, the kick-down switch described in Patent Document 1 mentioned above has a structure in which the pushing force of the actuating body is received by a coil spring. Therefore, if the accelerator pedal is continued to be depressed beyond the permissible stroke of the actuating body, the coil springs may come into close contact with each other, and the actuating body may be pushed harder than the permissible limit, causing damage to the kick-down switch. .

Moreover, when attaching a pedal switch to a pedal as described above, it is assumed that it is attached to the tread surface side (front side) of the pedal for easy attachment. However, when the pedal switch is attached to the tread surface side of the pedal, there is a problem in that it affects the height of the tread surface, thereby interfering with pedal operation. Further, when the pedal bottoms out on the floor part, all the pedal force is input to the switch side, so there is a concern that the pedal switch may be damaged.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a vehicle switch and a kickdown switch that can suppress damage and improve durability. Another object of the present invention is to provide a vehicle switch and a kickdown switch that can be easily retrofitted.

(1) A vehicle switch of the present invention provided to solve the above-mentioned problems is a vehicle switch arranged on a pedal of a vehicle, the switch being arranged on the back side of the pedal so as to face the floor of the vehicle. an actuating body that is arranged and capable of approaching and separating from and moving toward the back side of the pedal by coming into contact with the floor portion; and a stopper portion that protrudes toward the floor portion, the actuating body is capable of switching the switch from a non-operating state to an operating state by moving a predetermined stroke toward the back side of the pedal, and in the non-operating state of the switch, the floor portion is closer to the protruding end of the stopper portion. The actuator is characterized in that it protrudes by a predetermined protrusion amount toward the actuator, and the protrusion amount is configured to be greater than or equal to a predetermined stroke and less than or equal to the maximum movement stroke of the actuating body.

In the above-mentioned vehicle switch, when the switch is in a non-operating state, the actuating body projects toward the floor part by a predetermined amount beyond the projecting end of the stopper part. Further, the above-mentioned vehicle switch is configured such that the protrusion amount is greater than or equal to a predetermined stroke for switching the switch into an activated state and less than or equal to a maximum movement stroke of the actuating body. In other words, in the vehicle switch described above, after the actuating body moves a predetermined stroke and is switched to the actuated state, the stopper part comes into contact with the floor part before the actuating body reaches its maximum travel stroke. There is. Therefore, the above-mentioned vehicle switch can suppress the load on the operating body. This improves the durability of the vehicle switch described above. Here, the amount of protrusion of the actuating body from the stopper part can be changed as appropriate depending on the switch to be used, the shape of the floor part, etc.

(2) In the above-described vehicle switch of the present invention, the stopper portion may be configured to be detachable from the pedal.

By having such a configuration, the above-described vehicle switch can be provided with an appropriate stopper portion depending on the shape of the floor portion of the vehicle. That is, in the above-mentioned vehicle switch, the amount of movement (stroke) of the operating body in the vehicle switch can be limited on the stopper side. This improves the versatility of the vehicle switch described above.

(3) The above-described vehicle switch of the present invention has a bracket that is disposed on the floor portion and that can come into contact with the actuating body when the pedal is operated; It is preferable that a contact surface intersecting the moving direction of the actuating body is formed at the position of contact with the body.

By having the above-mentioned vehicle switch having such a configuration, the operability of the vehicle switch can be improved. That is, the above-mentioned vehicle switch has a contact surface that intersects with the moving direction of the actuating body, so that the actuating body can be reliably brought into contact with the bracket (floor portion). Moreover, since the above-mentioned vehicle switch can adjust the operating state of the actuating body using the bracket, the versatility of the vehicle switch can be increased.

(4) In the above-described kick-down switch of the present invention, the above-mentioned vehicle switch is disposed on the back side of an accelerator pedal, and when the accelerator pedal is operated, the actuating body comes into contact with the floor portion. It is characterized in that the non-operating state and the operating state can be switched by contacting each other.

By having such a configuration, the kick-down switch described above can be used as a kick-down switch for an accelerator pedal. As a result, the above-described kickdown switch can be expected to have improved durability.

The present invention can provide a vehicle switch and a kickdown switch that can suppress damage and improve durability. Further, the present invention can provide a vehicle switch and a kickdown switch that can be easily retrofitted.

FIG. 2 is a perspective view of FIG. 1 viewed from the side. 3(a) is a side view of a main body portion of a vehicle switch according to an embodiment of the present invention, and FIG. 3(b) is an exploded view of the vehicle switch of FIG. 3(a). (a) is an operation explanatory diagram of a vehicle switch according to an embodiment of the present invention mounted on an accelerator pedal, viewed from the side, and (b) is a perspective view of FIG. 4(a). . FIG. 1 is a perspective view of an embodiment of a bracket used in a vehicle switch of the present invention. (a) and (b) are explanatory diagrams showing the operating principle of the vehicle switch of the present invention.

Hereinafter, a vehicle switch 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6. In addition, in this embodiment, the case where the vehicle switch 1 is a kick-down switch (hereinafter also referred to as kick-down switch 1) provided around the accelerator device 2 of the vehicle as shown in FIG. 1 will be explained as an example. .

As shown in FIGS. 1 and 2, the accelerator device 2 is provided around a floor portion 3 formed below the driver's seat side of the vehicle. The accelerator device 2 includes an accelerator pedal 50 (also referred to as pedal 50), a support arm 51 that supports the accelerator pedal 50, a swing shaft 52 that swingably supports the support arm 51 (see FIG. 2), and an accelerator pedal. The kickdown switch 1 of the present invention is provided on the back side of the switch 50.

The accelerator pedal 50 is attached to the lower end side of the support arm 51. The upper end side of the support arm 51 is swingably supported by a swing shaft 52 . The support arm 51 is biased with an appropriate force by a spring or the like (not shown). Therefore, when the driver depresses the accelerator pedal 50, the accelerator pedal 50 swings via the support arm 51 in accordance with the force of the depressing. The vehicle detects the amount of depression of the accelerator pedal 50 using an appropriate sensor (not shown), and performs acceleration control according to the amount of depression.

As shown in FIG. 3(a), a kickdown switch 1 is attached to the back side of the accelerator pedal 50. The kickdown switch 1 is attached to an accelerator pedal 50 so that an actuating body 20 (described later) faces a bracket 40 provided on a floor portion 3 (see FIGS. 1 and 2). Although details will be described later, the kickdown switch 1 is switched between a non-operating state and an operating state when the actuating body 20 comes into contact with the contact surface 43 of the bracket 40 as the accelerator pedal 50 is operated.

Next, the configuration of the kickdown switch 1 of the present invention will be explained in detail below with reference to FIG. 3(b). In the following description, the direction perpendicular to the back surface of the accelerator pedal 50 (the left-right direction in the drawing) will be described as the up-down direction for convenience.

FIG. 3(b) is an exploded view showing a state in which the kickdown switch 1 is removed from the accelerator pedal 50. The kickdown switch 1 includes a switch body 10, a stopper portion 30, and the like. The switch body 10 includes an accommodating portion 11 as a case, an actuating body 20, and the like.

The housing portion 11 is formed as a substantially rectangular box, and the bottom surface is supported by a bolt or the like on the back side of the accelerator pedal 50. The accommodating portion 11 accommodates and supports the actuating body 20 so as to be able to reciprocate in the vertical direction. Further, a coil spring 12 for biasing the actuating body 20 is provided in the housing portion 11 along the vertical direction.

The actuating body 20 is formed in a cubic shape, and is arranged so that the upper surface side faces the floor portion 3 (in this embodiment, the contact surface 43 of the bracket 40) (see FIG. 1). The actuating body 20 is urged upward by a coil spring 12 provided in the housing portion 11 . As shown in FIGS. 4(a) and 4(b), the actuating body 20 resists the biasing force of the coil spring 12 by abutting the upper surface side with the contact surface 43 (see FIG. 5) of the bracket 40. You can push it downwards. Thereby, the actuating body 20 can move towards and away from the back side of the accelerator pedal 50. By pushing the operating body 20 downward with a predetermined stroke, the vehicle switch 1 can be switched from a non-operating state to an operating state. Here, the predetermined stroke is defined as the stroke from the upper end position (biasing end) of the actuating body 20 to the operating state in which the vehicle switch 1 starts operating (the state in which the switch is turned on). More specific details will be explained in the explanation of the operation of the vehicle switch 1, which will be described later.

The stopper part 30 is formed as a case surrounding the switch body 10, and is detachably fixed to the back side of the accelerator pedal 50. Thereby, the stopper part 30 is supposed to protrude toward the floor part 3.

Here, the actuating body 20 is designed to protrude toward the floor part 3 by a predetermined protrusion amount beyond the protruding end 30A of the stopper part 30 when the vehicle switch 1 is in a non-actuated state. Thereby, the stopper portion 30 is configured to restrict a portion of the movement of the actuating body 20 in the vertical direction. Specifically, when the actuating body 20 comes into contact with the contact surface 43 of the bracket 40 and is pushed in, the stopper part 30 abuts against the bracket 40 or the floor part 3 at a predetermined position, and the actuating body 20 is pushed in by a certain amount. It is assumed that the limit is such that it is not pushed in beyond the maximum movement stroke d3 (see FIG. 6). Although details will be described later, the maximum movement stroke d3 is set as the so-called play of the actuating body 20.

As shown in FIGS. 1 and 2, the bracket 40 is removably fixed to the floor portion 3 with bolts 44. As shown in FIG. 5, the bracket 40 is formed with a protrusion 42 that protrudes from a base plate 41 in a substantially triangular prism shape. The protruding portion 42 has a contact surface 43 formed to face the actuating body 20 . Further, the bracket 40 can hold down a floor mat (not shown) installed on the floor portion 3 at the outer peripheral edge portion. Thereby, the bracket 40 can prevent the kickdown switch 1 and the accelerator pedal 50 from interfering with the floor mat.

The contact surface 43 is formed substantially flat and can come into contact with the actuating body 20 as the accelerator pedal 50 is depressed. The abutting surface 43 is arranged so as to face a direction intersecting the moving direction of the actuating body 20 (in this embodiment, a direction substantially perpendicular to the moving direction of the actuating body 20) at the abutting position with the actuating body 20. There is.

The above is the configuration of the kickdown switch 1 (vehicle switch 1) according to one embodiment of the present invention. Next, the operation and operating principle of the kickdown switch 1 will be described below.

FIG. 6(a) is an explanatory diagram showing the operation of the kickdown switch 1, and FIG. 6(b) is an explanatory diagram showing the operating principle of the kickdown switch 1. Note that in FIG. 6, the bracket 40 is omitted for easy understanding.

As shown in FIG. 6(a), the actuating body 20 comes into contact with the floor portion 3 as the accelerator pedal 50 is depressed. By continuing to press the accelerator pedal 50, the actuating body 20 is pushed toward the back side of the accelerator pedal 50 by the floor portion 3. Further, when the accelerator pedal 50 is depressed by a predetermined amount, the stopper portion 30 comes into contact with the floor portion 3, and the depression of the accelerator pedal 50 is restricted. The relationship between the limit on the depression of the accelerator pedal 50 and the movement stroke of the operating body 20 at this time will be explained with reference to FIG. 6(b).

FIG. 6(b) shows a non-operating state in which the actuating body 20 is not pushed in (left side in the drawing) and a state in which the stopper portion 30 is in contact with the floor portion 3 (right side in the drawing). For ease of understanding, an example will be described in which the position where the switch is activated by the actuating body 20 and the position where the stopper part 30 contacts the floor part 3 are the same. Further, each operating position will be explained with reference to the bottom side of the operating body 20.

The actuating body 20 is allowed to move from an initial position P1 (non-pushed state) to a maximum movement position P3. Here, the distance between the initial position P1 and the maximum movement position P3 is set as the maximum movement stroke d3.

Further, a switch actuation position P2 (also referred to as switch contact P2) is set between the initial position P1 and the maximum movement position P3 for switching the switch (vehicle switch 1) into an actuated state. Further, the distance between the upper surface of the actuating body 20 at the initial position P1 and the protruding end 30A of the stopper portion 30 is set as the protruding amount d2.

Further, the distance from the initial position P1 to the switch actuation position P2 is set as the predetermined stroke d1. In addition, in this embodiment, since the position where the stopper part 30 and the floor part 3 contact each other is the same as the switch actuation position P2 as described above, the position between the initial position P1 and the contact position of the floor part 3 is The distance corresponds to the predetermined stroke d1.

The kickdown switch 1 (vehicle switch 1) of the present invention has the above-described configuration, thereby achieving the following effects.

As described above, the vehicle switch 1 of the present invention is configured such that the protrusion amount d2 of the actuating body 20 from the stopper portion 30 is greater than or equal to the predetermined stroke d1 of the actuating body 20 and less than or equal to the maximum movement stroke d3 of the actuating body 20. There is. In other words, in the vehicle switch 1 described above, after the actuating body 20 moves by a predetermined stroke d1 and is switched to the actuating state, the stopper part 30 moves to the floor part 3 before the actuating body 20 reaches the maximum movement stroke d3. It is said that it is in contact with. Therefore, the vehicle switch 1 described above can suppress the load on the actuating body 20. This improves the durability of the vehicle switch 1 described above. Here, the protrusion amount d2 of the actuating body 20 from the stopper part 30 can be changed as appropriate depending on the switch to be used, the shape of the floor part 3, and the like.

Further, the vehicle switch 1 described above is configured such that the stopper portion 30 is removably attached to the pedal 50. Therefore, the vehicle switch 1 described above can be provided with an appropriate stopper portion 30 depending on the shape of the floor portion 3 of the vehicle. That is, in the vehicle switch 1 described above, the amount of movement (stroke) of the operating body 20 in the vehicle switch 1 can be limited on the stopper portion 30 side. This improves the versatility of the vehicle switch 1 described above.

Further, in the vehicle switch 1 described above, a bracket 40 that can come into contact with the actuating body 20 is disposed on the floor portion 3, and the bracket 40 has the actuating body 20 at the position of contact with the actuating body 20. A contact surface 43 is formed that intersects the direction of movement of. Therefore, the vehicle switch 1 described above can improve the operability of the vehicle switch 1. That is, the above-described vehicle switch 1 has the contact surface 43 that intersects the moving direction of the actuating body 20, so that the actuating body 20 can be reliably brought into contact with the bracket 40 (floor portion 3). Moreover, since the above-described vehicle switch 1 can adjust the operating state of the operating body 20 using the bracket 40, the versatility of the vehicle switch 1 can be increased.

The operation flow and effects of the vehicle switch 1 of the present invention have been described above, but the vehicle switch 1 of the present invention is not limited to the above-described embodiments, and can be modified in various ways.

It is possible to use the switch 1 for a vehicle. For example, the vehicle switch 1 may be configured as a switch in an erroneous start suppression device. Further, in this embodiment, the case where the vehicle switch 1 is a push-in switch is illustrated, but the vehicle switch 1 is not limited to a push-in switch, and can be used in various types of switches.

In the present embodiment, the stopper section 30 is configured to be detachable from the pedal 50, but the stopper section 30 is not only detachable from the pedal 50 but also fixed. It can be in various forms such as objects. Further, the stopper section 30 can be used not only in a box shape but also in various shapes and sizes. For example, the stopper portion 30 may be formed of something such as a bolt or a guide pin. Further, the protrusion amount d2 of the actuating body 20 from the stopper portion 30 can be changed as appropriate depending on the characteristics of the vehicle switch 1, the shape of the floor portion 3 (including the bracket 40), and the like.

In this embodiment, the bracket 40 is provided on the floor portion 3, and the contact surface 43 of the bracket 40 and the operating body 20 are in contact with each other, but the bracket 40 may be provided as necessary. Further, when the bracket 40 is provided, its shape can be changed as appropriate to match the shape of the floor portion 3.

The above are various embodiments and modified examples of the vehicle switch 1 (kick down switch 1) according to the present invention, but the present invention is not limited to the embodiments and modified examples described above.
