[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to a parking system equipped with a vehicle, which has a pedal section in the passenger compartment of a vehicle and is rotatably disposed, and is rotated when the pedal section is depressed. The present invention relates to a parking brake operating device for a vehicle that includes a rotating operating member that allows a brake mechanism to take an operating state and an operating state.

2. Description of the Related Art In a parking brake operating device that controls a parking brake mechanism installed in a vehicle to selectively take an activated state and a deactivated state, a lever-like rotation operation that is manually operated and rotated is used. A manual type in which the member is provided inside the passenger compartment, or a pedal part that has a pedal part at one end that is operated by stepping inside the passenger compartment, as shown in Japanese Utility Model Application Publication No. 61-141162, for example. A foot-operated vehicle is known in which an arm-shaped rotation operation member that is rotated by being depressed is provided in the vehicle interior. In a foot-operated parking brake operation device, when an arm-shaped rotation operation member having a pedal portion at one end is capable of depressing the pedal portion, the parking brake mechanism The parking brake mechanism is caused to take an activated state when the pedal part is depressed and rotated. In addition, the rotation operation member is
A sector gear portion is provided at the other end, and is biased by a spring member or the like to take a brake release position that causes the parking brake mechanism to take an action release state. Further, in connection with such a rotation operation member, a brake operation is performed in which the rotation operation member is brought into an operating state by the parking brake mechanism by engaging with a sector gear portion provided at the other end of the rotation operation member. a ratchet mechanism that is held in position, and a ratchet mechanism that engages with the sector gear portion of the rotation operation member to hold the rotation operation member in the brake operation position; A release mechanism is provided for returning the rotary operation member to the brake release release position by bringing the brake into a release state.

[0003] In such a foot-operated parking brake operation device, the rotary operation member is rotated to take the brake operation position when the pedal is depressed from the brake operation release position. When the rotation operation member is rotated, the sector gear section provided at the other end of the rotation operation member is moved as the rotation operation member rotates.
The engagement position of the ratchet mechanism with respect to the sector gear section changes from the position where the rotary operating member assumes the brake release position to the position where the ratchet mechanism intermittently abuts and engages with the sector gear section as the sector gear section starts. When the rotary operating member is changed to the position in which it is held in the brake operating position under the condition that The ratchet mechanism, which is engaged with the sector gear portion of the rotational operation member at a position for holding the rotational operation member in the brake operation position, temporarily stops the engagement with the sector gear portion of the rotational operation member using the release mechanism. It is assumed that the state is to be released.

0004

[Problem to be Solved by the Invention] In the above-mentioned foot-operated parking brake operating device, the rotary operating member is rotated by depressing the pedal portion from the brake release release position. When the braking operation position is assumed, the sector gear portion provided at the other end of the rotary operating member is moved, and the ratchet mechanism is intermittently abutted and engaged with the sector gear portion. At that time, there is a problem in that a relatively large engagement noise is generated between the ratchet mechanism and the sector gear portion, and the engagement noise is propagated into the vehicle interior as undesirable noise.

[0005] Therefore, when the rotary operating member is rotated by depressing the pedal from the brake release position and assumes the brake operation position, the ratchet mechanism rotates it. By setting the biasing force that acts to bring the sector gear provided at the other end of the operating member into contact with it to be relatively small,
It is conceivable to suppress the engagement noise generated by the ratchet mechanism intermittently abutting and engaging with the sector gear portion. However, if the engagement noise generated by the intermittent contact and engagement of the ratchet mechanism with the sector gear portion is suppressed and not propagated into the vehicle interior, the braking operation of the rotation operating member As a result, it becomes difficult to confirm that the parking brake has rotated reliably from the release position to the brake application position, and for example, a driver of a vehicle who depresses the pedal of the rotation operation section may feel uneasy about operating the parking brake. This is an inconvenience.

[0006] In view of the above, the present invention provides a system in which a rotary operation member for a parking brake disposed inside a vehicle interior is rotated from a brake release position to a brake operation position. When it is said that
Even though the ratchet mechanism for the sector gear provided at the other end of the rotation operation member is intermittently abutted and engaged with the sector gear, the engagement noise generated by this is attempted to be reduced. It is an object of the present invention to provide a parking brake operating device for a vehicle, in which reliable rotation of a parking brake from a brake release position to a brake operation position can be easily confirmed.

[0007]

[Means for Solving the Problems] In order to achieve the above-mentioned object, a parking brake operating device for a vehicle according to the present invention has the following features:
A rotary operating member rotatably disposed in a vehicle interior and controlling the operating state of a parking brake mechanism installed in the vehicle by being rotated, and a rotary operating member that is interlocked with the rotary operating member. , and a melody generation section that plays a specific melody in response to the rotation of the rotation operation member.

[0008]

[Operation] In the parking brake operating device for a vehicle according to the present invention constructed as described above, for example, the rotation operating member has a pedal section and is rotated when the pedal section is depressed. , when the brake operation is rotated from the brake release position to the brake operation position, the engagement noise generated by the ratchet mechanism intermittently abutting and engaging with the sector gear provided on the rotation operation member is reduced. In place of the engagement sound, a specific melody will be emitted by the melody generating section,
Therefore, the rotation operation member can be reliably rotated from the brake operation release position to the brake operation position without any undesirable engagement noise generated by the sector gear section and the ratchet mechanism provided on the rotation operation member. It will be confirmed by a specific melody from the melody generator.

In the example shown in FIG. 2, the arm member 1 and the positioning mechanism section 2 for the arm member 1 are attached to a bracket 4 fixed to the body of a vehicle (not shown).
Each is rotatably attached. The arm member 1 extends along the bracket 4 and has an upper side portion with a relatively large width dimension, and an upper side portion that extends outward from the bracket 4 and has a relatively small width dimension and is curved. It has a lower side portion, and is rotatably supported by a shaft member 6 fixed to the bracket 4 at its upper side portion, and is rotated in the direction shown by arrow A (A direction) and the direction indicated by arrow B (direction B)
It is said that it can be rotated in either direction.

An arcuate sector gear 8 extending in the width direction is attached to the end of the upper part of the arm member 1, and one end is connected to a brake device installed on the vehicle body. The other end of the parking brake cable 10 is connected. Furthermore, a pedal portion 1a that is depressed by the driver of the vehicle is provided at the end of the lower portion of the arm member 1. Further, a damper 11 with a return spring is interposed between the arm member 1 and the bracket 4, which urges the arm member 1 to rotate in the B direction at all times.

As shown by the solid line in FIG. 2, the arm member 1 is urged to rotate in direction B by a damper 11 with a return spring and is brought into contact with a stopper member 12 provided on the bracket 4. , when the rotation in direction B is restricted, the parking brake cable 10 is loosened and the parking brake cable 10 and the brake device etc. are moved to a position where the brake device installed on the vehicle body is not operated. When the parking brake mechanism including the parking brake mechanism is set in a brake release position, and the pedal portion 1a is depressed, the parking brake mechanism is moved from the brake release position to resist the biasing force of the damper 11 with a return spring. When the parking brake cable 10 is pulled up and rotated in direction A, the parking brake cable 10 is pulled up to a position where a brake device installed on the vehicle body is operated, that is, a brake operation position where the parking brake mechanism is put into an operating state. The positioning mechanism 2 attached to the bracket 4 maintains the arm member 1 in the braking position.

The positioning mechanism section 2 has a shaft member 13 fixed to the bracket 4 and positioned opposite to the sector gear 8 attached to the end of the upper part of the arm member 1.
, a bending lever member 16, a plate member 17 and a ratchet member 18 rotatably attached to the shaft member 13, a stopper member 14 fixed to the bracket 4 and arranged between the shaft member 13 and the sector gear 8, etc. It is composed of: The bent lever member 16 has a first part 16a whose bent part is supported by the shaft member 13, extends downward from the bent part, and has one end of the release cable 19 connected to its tip, and a first part 16a that extends downward from the bent part. It extends toward the sector gear 8 attached to the arm member 1, and the tip end is connected to the stopper member 1.
4 and a second portion 16b that engages with the shaft member 13, and can be rotated about the shaft member 13 as a rotation center axis. The other end of the release cable 19, one end of which is connected to the tip of the first portion 16a of the bending lever member 16, is connected to a release lever (not shown). When the lever is operated, the bending lever member 16 is rotated in the direction shown by arrow C in FIG. 2 (direction C).

The plate member 17 constituting the positioning mechanism section 2 has one end supported by the shaft member 13 and extends along the second portion 16b of the bending lever member 16, and the other end thereof is supported by the shaft member 13 and extends along the second portion 16b of the bending lever member 16. The second portion 16b of the lever member is configured to abut against a plate receiving portion 16c provided at the distal end portion that engages with the stopper member 14 and to face the stopper member 14, and is a bending lever member with the shaft member 13 as the central axis of rotation. 16. A toggle spring 20 is fitted into the shaft member 13, one end of the toggle spring 20 contacts a pin 21 fixed to the bracket 4, and the other end of the toggle spring 20 contacts a bending lever. A plate member 17 that comes into contact with a plate receiving portion 16c provided on the second portion 16b of the member 16
It is said that it engages with the tip of the Thereby, the toggle spring 20 biases the plate member 17 so that its tip end is pressed against the plate receiving portion 16c provided on the second portion 16b of the bending lever member 16, and The member 16 is biased such that the tip of the second portion 16b is pressed against the stopper member 14. The toggle spring 20 is selected to have a relatively large biasing force against the plate member 17 and the bending lever member 16, thereby reliably regulating the positions of the bending lever member 16 and the plate member 17. It is said that

A shaft member 23 is provided at the tip of the plate member 17, and the ratchet member 18 is rotatably supported by the shaft member 23. Shaft member 2
3 is fitted with a toggle spring 24. One end of the toggle spring 24 engages with the plate member 17 and the other end engages with the ratchet member 18. The plate member 17 is urged to rotate clockwise about the shaft member 23 as a rotation center axis. Such toggle spring 2
4 is selected so that the biasing force on the ratchet member 18 is smaller than the biasing force exerted by the toggle spring 20 on the plate member 17 and the bending lever member 16, which is relatively small.

A ratchet member 18 supported by a shaft member 23 at the tip of the plate member 17 and biased by a toggle spring 24 is connected to the release cable 1.
9 is not in a state in which the bending lever member 16 is rotated in the C direction, and the bending lever member 16 and the plate member 17, which are biased by the toggle spring 20, are in a state in which the positions are regulated by the stopper member 14. Here, the tip end 18a is engaged with the sector gear 8 attached to the arm member 1, while the release cable 19 moves the bending lever member 16 in the C direction against the biasing force of the toggle spring 20. When the distal end portion of the second portion 16b of the bending lever member 16 and the distal end portion of the plate member 17 are separated upwardly from the stopper member 14, the distal end portion 1
8a is separated from the sector gear 8 attached to the arm member 1, and the engagement with the sector gear 8 is released.

The distal end 18a of the ratchet member 18 forms a pawl that prevents the arm member 1 from rotating in the direction B when engaged with the sector gear 8. When the position is regulated by the stopper member 12 to take the brake release position as shown by the solid line in FIG. 2, the distal end 18a of the ratchet member 18 is engaged with the sector gear 8 as shown by the solid line in FIG. Matching position is sector gear 8
shall be placed on the upper end side of, and
When the pedal portion 1a is depressed, the arm member 1 is rotated in the direction A from the brake release position against the biasing force of the damper 11 with a return spring, as shown by the dashed line in FIG. When the brake operation position is assumed as shown in FIG. As shown, the engagement position of the tip 18a of the ratchet member 18 with the sector gear 8 is shifted to the lower end side of the sector gear 8, and the ratchet member 18 prevents the arm member 1 from rotating in the direction B. Therefore, the state in which the arm member 1 assumes the braking operation position is maintained.

A cylindrical member 30 that surrounds the shaft member 6 fixed to the bracket 4 is fixed to the arm member 1, and this cylindrical member 30 moves as the arm member 1 rotates. It rotates around the shaft member 6. As shown in FIG. 1, the cylindrical member 30 has a plurality of pins 31 arranged in a predetermined manner upright on its outer peripheral surface. Further, an elastic plate-like member 33 extending toward the shaft member 6 is attached to the bracket 4, and a large number of strips 33a are arranged in the elastic plate-like member 33. The distal end portion of each of the cylindrical members 33a faces the outer circumferential surface of the cylindrical member 30. When the cylindrical member 30 rotates around the shaft member 6 as the arm member 1 rotates, the large number of strips 33a provided on the elastic plate-like member 33 stand up against the cylindrical member 30. Multiple pins 3
1 are brought into contact with each other one after another, whereby each of them is vibrated to form a sounding section that plays a preset melody. That is, the cylindrical member 30 and the elastic plate-like member 33 form a music box mechanism.

As described above, in one example of the parking brake operating device according to the present invention, in which the music box mechanism is provided in association with the arm member 1, the arm member 1 is positionally regulated by the stopper member 12 so as to be in the brake release position. The ratchet member 1 forming the positioning mechanism section 2 is placed in the position shown by the solid line in FIG.
When the tip end 18a of the sector gear 8 is engaged with the upper end portion of the sector gear 8, the pedal portion 1a of the arm member 1 is depressed, and the arm member 1 releases the brake operation. When the damper 11 with a return spring is rotated in the direction A against the biasing force of the damper 11 to take the brake operating position, the parking brake cable 10 is pulled up and the parking brake mechanism is put into the operating state. Ru.

When the arm member 1 is rotated from the brake operation release position to the brake operation position, the bending lever member 16 and the plate member 17, which constitute the positioning mechanism section 2, are moved by the attachment of the toggle spring 20, respectively. The sector gear 8 is placed in a state where its position is regulated by the stopper member 14 under force, and the tip 18a of the ratchet member 18 is attached to the end of the upper part of the arm member 1.
As the sector gear 8 moves with the rotation of the arm member 1, the ratchet member 18 is caused to swing about the shaft member 23 as the central axis of rotation, and the distal end 18a of the ratchet member 18 is rotated. It intermittently abuts and engages with the moving sector gear 8. However, the ratchet member 18 is relatively small and lightweight, and the toggle spring 24 transfers the urging force to the ratchet member 18 from the plate member 17 by the toggle spring 20.
and is smaller than the biasing force against the bending lever member 16.
By being selected to be relatively small,
The engagement noise generated by the intermittent contact and engagement of the distal end 18a of the ratchet member 18 with the moving sector gear 8 is relatively small, and is so small that it is transmitted as undesirable noise into the vehicle interior. It is not considered to belong to

On the other hand, a plurality of pins 31 are provided on the outer peripheral surface.
A music box mechanism is formed by a cylindrical member 30 on which is erected and an elastic plate-like member 33 on which a large number of strips 33a are arranged. As a result of the rotation, the plurality of pins 31 provided upright on the cylindrical member 30 are brought into contact with the plurality of strips 33a provided on the elastic plate-like member 33 one after another, and the plurality of strips 33a are brought into contact with each other.
Each of the a is vibrated to play a preset melody. Therefore, in response to the rotation of the arm member 1 from the brake operation release position to the brake operation position, the music box mechanism plays a preset melody.

When the arm member 1 reaches the brake operating position, the distal end 18a of the ratchet member 18 is connected to the sector gear 8, as shown by the solid line in FIG. The arm member 1 is engaged with the lower end portion to prevent the arm member 1 from rotating in the direction B, thereby allowing the arm member 1 to take the brake operating position and the parking brake mechanism to be in the operating state. maintained.

In this way, when the arm member 1 is rotated from the brake operation release position to the brake operation position,
The contact noise caused by the distal end 18a of the ratchet member 18 contacting and engaging with the sector gear 8 is suppressed, and instead of this, the cylindrical member 3 provided in relation to the arm member 1
By making it possible to obtain the melody from the music box mechanism consisting of the 0 and the elastic plate member 33, undesirable noise accompanying the rotation of the arm member 1 from the brake release position to the brake operation position can be effectively suppressed. The driver of the vehicle can easily confirm with the melody from the music box mechanism that the arm member 1 has been surely rotated from the brake operation release position to the brake operation position.

3, the ratchet member 18 is shown by a solid line, and the sector gear 8 is attached to the lower end portion of the sector gear 8 attached to the arm member 1, as shown by the dashed line. 18a is engaged and the arm member 1 is maintained in the brake operating position, the release lever is operated and the release cable 19 is moved to the bending lever member in order to cause the parking brake mechanism to take the operating release state. 16 against the biasing force of the toggle spring 20
3, the tip of the second portion 16a of the bending lever member 16 and the tip of the plate member 17 are moved upward, and the stopper is moved upward. The ratchet member 18 is separated from the sector gear 8 as the distal end portion of the plate member 17 moves upward, and the distal end portion 18a of the ratchet member 18 engages with the sector gear 8. is canceled. As a result, the arm member 1 is released from the restraint state in which it assumes the brake operation position, and the damper 1 with a return spring is released.
The biasing force of 1 rotates in the direction B from the brake operation position and returns to the brake release position.

At this time, as shown by the two-dot chain line in FIG. 3, the end portion 18a of the ratchet member 18 is directed downward by the biasing force of the toggle spring 24, so that the ratchet member 18 is not engaged with the sector gear 8. be in a state of avoidance. Further, when the arm member 1 is rotated from the brake operation position to the brake operation release position in this way, the plurality of pins 31 erected on the cylindrical member 30, which is rotated with the arm member 1, The music box mechanism is brought into operation by coming into contact with a large number of strips 33a provided on the elastic plate member 33, but when the arm member 1 is moved from the brake operation position to the brake operation release position. Since the rotation takes place within an extremely short period of time, the sound produced by the music box mechanism at that time is considered to be almost negligible.

Note that when the release lever is operated to cause the parking brake mechanism to be released, the bending lever member 16 is rotated in the C direction against the biasing force of the toggle spring 20, and the ratchet member is rotated. 18 is separated from the sector gear 8 as the distal end of the plate member 17 moves upward, and after the engagement of the distal end 18a of the ratchet member 18 with the sector gear 8 is released, it returns to its original state within a short time. forced to return to the state,
The bending lever member 16 and the plate member 17 are returned to the position regulated by the stopper member 14 under the biasing force of the toggle spring 20 .

[0027]

As is clear from the above description, the parking brake operating device for a vehicle according to the present invention has, for example, a pedal section disposed in the cabin of a vehicle, and the pedal section can be operated by pressing the pedal. When the rotary operation member is rotated from the brake release position to the brake operation position, the ratchet mechanism intermittently contacts a sector gear provided on the rotation operation member. Although the engagement sound generated by engagement is reduced, a specific melody is emitted by the melody generating section in place of the engagement sound, so that the brake operation of the rotation operating member is released. Reliable rotation from the position to the brake operation position is confirmed by a specific melody from the melody generating section, without the undesirable engagement noise generated by the sector gear section and ratchet mechanism provided on the rotation operation member. You will be able to do so.
