Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for supporting an operation pedal disposed behind a dash panel of an automobile.

[0002]

2. Description of the Related Art When a vehicle collides with an obstacle ahead,
The front of the car body collapses while absorbing the collision energy,
The engine disposed in the engine room moves backward while pressing the master cylinder of the brake device located on the rear side. Since a brake pedal located at the rear of the dash panel is connected to the master cylinder via a rod, the brake pedal is also pushed and retreated with the retraction of the master cylinder. Therefore, at the time of this collision, a collision load acts on the driver's foot that is stepping on the brake pedal, causing a large kickback, and causing a problem that the driver's knee is impacted.

On the other hand, Japanese Patent Application Laid-Open No. 11-43073 discloses that a stopper member (pressing member) is projected forward from a vehicle body component member behind a suspension type vehicle pedal, and the stopper member is retracted by a collision. It describes that an incoming vehicle pedal is applied to the stopper member. The position where the vehicle pedal contacts the stopper member is below the pivot point. Therefore, when the vehicle pedal hits the stopper member, it rotates about the pivot point and the tip pedal moves forward, thereby reducing the collision load acting on the driver's foot.

Japanese Patent Application Laid-Open No. 11-59350 discloses that when a collision load of a predetermined value or more is input to a push rod of a brake pedal of an automobile in a retreating direction, the push rod is released from the brake pedal so that the brake is released. It is described that the collision load input to the pedal is reduced.

[0005]

As described above, even if the operation pedal is rotated and displaced so that the tip pedal moves forward by applying the lower side of the pivot point of the operation pedal to the stopper member, the operation pedal can be moved. When the rod is connected to the operated rod, the rod may hinder the rotational displacement of the operation pedal. On the other hand, Japanese Patent Laid-Open No. 11-59350
As described in Japanese Patent Application Laid-Open Publication No. H10-260, it is conceivable to release the operation pedal when a collision load of a predetermined value or more is input to the rod.

However, in this case, even if the operating pedal hits the stopper member, the rod does not come off the operating pedal until a collision load of a predetermined value or more is input to the rod.
During that time, the rotational displacement of the operation pedal is hindered. Then, since the phenomenon that the operating pedal retreats at the time of a collision is instantaneous, if the rotational displacement is prevented until a collision load of a predetermined value or more is input to the rod, even if the rod subsequently comes off the pedal, However, it is inevitable that a relatively large collision load acts on the driver's foot. In addition, it is difficult to instantaneously release the rod from the operation pedal from the time when a collision load of a predetermined value or more is input to the rod until a large collision load is applied to the driver's foot. I cannot get reliability.

SUMMARY OF THE INVENTION It is an object of the present invention to reliably prevent a large load from acting on a driver's foot due to an excessive retreat of an operation pedal at the time of a vehicle collision.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has been made so as to prevent the operation pedal from swinging forward when the operation pedal hits a stopper member. And the rod and the rod are disconnected.

That is, the invention according to claim 1 is a support device for an operation pedal disposed behind a dash panel of an automobile, the device being fixed to the dash panel and disposed behind the dash panel, A pedal bracket for supporting the operation pedal so as to be able to swing back and forth, a connecting member for detachably connecting the operation pedal and a rod operated by the operation pedal, and a connection member disposed behind the operation pedal; A stopper member for preventing a retreat of an intermediate point between a supporting point of the operation pedal with respect to the pedal bracket and a tip pedal portion when the dash panel and the pedal bracket are retracted by a predetermined amount or more;
The connecting member is provided so as not to prevent the operation pedal, which has been prevented from retreating by the stopper member, from swinging forward around the support point with the retraction of the support point. A disconnecting means for disconnecting the connection between the operation pedal and the rod is provided.

Therefore, according to the present invention, the operating pedal retreats toward the passenger compartment together with the dash panel and the pedal bracket at the time of a collision of the automobile. Blocked by the member. For this reason, when the support point of the operation pedal retreats further together with the pedal bracket, the operation pedal tries to rotate around the support point so that the tip pedal section moves forward, but the disconnecting means is operated by the connecting member. Since the connection between the pedal and the rod is disconnected, the rod does not hinder the rotation of the operation pedal. For this reason, at the time of a car collision, the tip pedal portion of the operation pedal surely moves forward, so that a large collision load is prevented from acting on the driver's foot.

According to a second aspect of the present invention, in the vehicle pedal support device according to the first aspect, when the connecting member is prevented from retreating following the operation pedal, the connection member is connected to the operation pedal. The stopper member is configured to release the connection with the rod, and the stopper member prevents the connection member from following the operation pedal when the operation pedal is retracted together with the dash panel and the pedal bracket. It is characterized in that the connection is disconnected.

That is, a disconnecting means can be provided separately from the stopper member, but in that case, a mechanism for disconnecting the connection immediately before the stopper member acts on the operation pedal becomes complicated.

Therefore, in the invention according to claim 2, the disconnecting means for connection is constituted by using the stopper member. In this case, the stopper member is provided with a second stopper portion for preventing a retreat of the connecting member following the operation pedal, separately from the first stopper portion for preventing the intermediate point of the operation pedal from retreating, and the first stopper portion is substantially provided. It is sufficient to set the positional relationship between the two stoppers so that the second stopper works before the second stopper works.

According to a third aspect of the present invention, in the vehicle pedal support device according to the second aspect, one point is pivotally supported by the pedal bracket, and the other point is a vehicle body rearward of the dash panel. A movable member that is fastened to the member so as to be disengaged when retracted together with the pedal bracket, and is capable of swinging back and forth around the one point by releasing the fastening, wherein the movable member includes:
A stopper abutting portion that abuts on the stopper member so as to be prevented from retreating after retreating together with the pedal bracket and releasing the engagement, and further retreats after the stopper abutting portion abuts on the stopper member. A connection disconnecting portion that disconnects the connection between the operation pedal and the rod by preventing the connection member from following the operation pedal and retreating against the connection member, and the connection between the operation pedal and the rod is disconnected. A pedal receiving portion for supporting the intermediate point of the operation pedal so as not to retreat by supporting the stopper member later.

Therefore, at the time of a collision of the vehicle, the movable member retreats together with the pedal bracket. However, when the movable member is released from being fastened to the vehicle body member, the movable member can swing back and forth with respect to the pedal bracket. Then, when the movable member further retreats, the stopper contact portion contacts the stopper member to prevent retreat, and then the connection disconnecting portion contacts the connection member to prevent the connection member from following the operation pedal and retreating. The connection between the operating pedal and the rod is disconnected, and the pedal receiving portion supports the stopper member to prevent the intermediate point of the operating pedal from retreating.

Therefore, by merely providing the movable member, it is possible to disconnect the connection between the operating pedal and the rod at the time of a collision of the vehicle, and to swing the operating pedal forward without being hindered by the rod by the function of the stopper member.

According to a fourth aspect of the present invention, in the vehicle pedal support device according to the third aspect, the operation pedal is provided at one of a pedal receiving portion of the movable member and an intermediate point of the operation pedal. Before the connection disconnecting portion hits the connection member when swinging to, there is provided a pedal switch that contacts a switch member provided on the other side and detects a swing end of the operation pedal rearward, Between the operating pedal and the movable member, when the retreat of the movable member is prevented by the stopper member, the connection and disconnection member further moves from the state where the pedal switch and the switch member are in contact with each other. Is provided with swing permitting means for allowing the operation pedal to swing backward relative to the movable member together with the connecting member until the connection is released. And said that you are.

That is, when the vehicle is not in a collision,
The movable member is in an integral relationship with the pedal bracket. Therefore, although the operation pedal swings back and forth with respect to the movable member, even if the operation pedal swings backward and the pedal switch and the switch member come into contact with each other at the swinging end, the connection of the movable member is prevented. It must be ensured that the disconnection does not hit the connecting member. On the other hand, at the time of the collision of the automobile, the movable member is disengaged from the vehicle body constituent member and is capable of swinging back and forth with respect to the pedal bracket. Contact state.

In this case, since the connecting member swings back and forth following the operating pedal (that is, integrally), the operating pedal is further moved from the state where the pedal switch and the switch member are in contact with each other. If it is not possible to swing backward with respect to the movable member together with the movable member, the coupling disconnection portion of the movable member cannot be applied to the coupling member to disconnect the connection between the operation pedal and the rod. Therefore, in the invention according to claim 4, the above-mentioned swing permitting means is provided.

[0020]

As described above, according to the first aspect of the present invention, when the operating pedal is retracted together with the dash panel and the pedal bracket, the connecting member for detachably connecting the operating pedal and the rod is connected to the connecting member. A stopper member is provided for preventing the intermediate point between the support point of the operation pedal with respect to the pedal bracket and the tip pedal portion, and the operation pedal whose intermediate point is prevented from being retracted by the stopper member is caused by the retraction of the support point. In order not to hinder relative swinging forward, the connection between the operation pedal and the rod by the connection member is separated, so that the tip pedal portion of the operation pedal is reliably moved forward in the event of a car collision. It is possible to move, and a large collision load is prevented from acting on the driver's foot.

According to the second aspect of the present invention, the stopper member prevents the connecting member from following the operating pedal when the operating pedal is retracted together with the dash panel and the pedal bracket. Since the disconnecting means for disconnecting the connection is configured, the mechanism for disconnecting the connection becomes simple.

According to the third aspect of the present invention, since the movable member including the stopper abutting portion, the connection disconnecting portion, and the pedal receiving portion is provided, the connection between the operating pedal and the rod is disconnected when the vehicle collides. The operation pedal can be swung forward by the function of the stopper member without being obstructed by the rod.

According to the fourth aspect of the present invention, the pedal switch and the switch member come into contact between the operation pedal and the movable member when the movable member is prevented from retreating by the stopper member. Further, a swing permitting means is provided for allowing the operating pedal to swing backward relative to the movable member together with the connecting member until the connecting / disconnecting member hits the connecting member and the connection is released. Therefore, the connection between the operation pedal and the rod can be reliably separated, and the movable member can be used also as a bracket for the pedal switch, which is advantageous in simplifying and reducing the structure.

It extends slightly.

The cowl panel 1 of the pedal bracket 5
As shown in FIG. 2, the upper end portion fastened to the upper end 2 has an upper wall 5a and left and right side walls 5b, and has a substantially inverted U-shaped cross section. On the other hand, the movable member 7 includes an upper wall 7a, a front wall 7b, left and right side walls 7c connecting the upper wall 7a and the front wall 7b, and a rear portion of the pedal arm 4a fixed to the side wall 7c and slightly behind. And a switch bracket 7d extending obliquely downward. Therefore, the upper end of the movable member 7 also has the upper wall 7a and the left and right side walls 7 like the pedal bracket 5.
c, the cross-sectional shape is substantially inverted U-shaped. Further, the switch bracket 7d and the stopper member 6 are substantially orthogonal to each other, and the tip of the stopper member 6 faces the rear surface of the switch bracket 7d.

Then, the upper wall 5a of the pedal bracket 5
Each of the upper walls 7a of the movable member 7 is formed with slits 17 corresponding to upper and lower sides which are opened forward.
The cowl panel 12 and the pedal bracket 5 and the movable member 7 are fastened by bolts 19 passing through the slits 17. Therefore, when the pedal bracket 5 and the movable member 7 receive a pressing force of a predetermined value or more toward the rear,
When the bolt 19 comes off from the slit 17, the fastening to the cowl panel 12 is released. Also,
The side wall 7c of the movable member 7 is the side wall 5b of the pedal bracket 5.
Is pivotally supported by a support shaft 13 of the brake pedal 4. Therefore, the movable member 7 is mounted on the cowl panel 12.
When the connection is released, it is possible to swing back and forth around the support shaft 13.

The movable member 7 has a stopper abutting portion 21 which abuts on the stopper member 6 in the event of a collision of a vehicle, and a connection separating portion 22 which abuts on the connecting member 16 and disconnects the connection between the brake pedal 4 and the push rod 15.
And a pedal receiving portion 23 that supports the stopper member 6 to support the intermediate point of the brake pedal 4 so as not to retreat.

That is, the back surface of the movable member 7 facing the stopper member 6 of the switch bracket 7d forms the stopper contact portion 21. The brake switch 9 is attached to a portion of the switch bracket 7 d below the stopper contact portion 21, in other words, a portion farther from the stopper contact portion 21 when viewed from the support shaft 13 of the brake pedal 4. . A switch member 24 is attached to the pedal arm 4a of the brake pedal 4 via a bracket 25 so as to face the brake switch 9. In this embodiment, the brake switch mounting portion of the switch bracket 7d forms the pedal receiving portion 23.

Further, a connecting / disconnecting portion 22 is formed on the front wall 7b of the movable member 7. First, the connection structure between the brake pedal 4 and the push rod 15 will be described. As shown in FIG. 3, a large diameter flange-like connection portion 15a is integrally formed at the rear end of the push rod 15. On the other hand, a pedal side rod 2
The joint part 27 at the rear end of the unit 6 is connected by a connecting pin 29 in the horizontal direction. At the front end of the pedal-side rod 26, a flange-shaped connecting portion 26a having the same diameter as the connecting portion 15a is integrally formed. The two connecting portions 15 a and 26 a are concentrically butted against each other and held by the connecting member 16.

The connecting member 16 is, as shown in FIG.
A pair of half-shaped collars 30, 30 made of resin or the like, which cover the connecting portions 15a, 26a in the abutted state so as to sandwich the connecting portions 15a, 26a from both sides in the diameter direction, and are externally fitted to the two collars 30, 30. Connecting the two collars 30, 30 to the connecting portions 15a, 26
a. Each color 30
The corresponding connecting portions 15a and 26a
An inward flange portion 30a is formed to cover the rear surface of the first member and prevent detachment of both connecting portions 15a and 26a.

The restraining member 31 includes two collars 30, 30.
And a flange portion 31b that protrudes outward from the front end of the cylindrical portion 31a.
The cylindrical portion 31a is externally fitted to the collars 30, 30 so as to slide out of the collars 30, 30 when a predetermined force or more is applied forward in the axial direction. 30 is the release of the connection
The rods 15 and 26 are disconnected from 5a and 26a.

On the other hand, the front wall 7b of the movable member 7
As shown in FIG. 5, an inverted U-shaped cutout portion 7e that opens downward is formed, and the periphery of the cutout portion 7e constitutes a connection disconnection portion 22. That is, the width D of the cutout portion 7e is equal to the width of the restricting member 31.
And the flange portion 31 is larger than the outer diameter of the cylindrical portion 31a.
The connecting and disconnecting portion 22 is loosely fitted to the cylindrical portion 31a and disposed on the back of the flange portion 31b. Accordingly, the connection / disconnection portion 22 of the movable member 7 is connected to the flange portion 31 b of the restraining member 31.
When the restraining member 31 falls forward from the collars 30, 30, the brake pedal 4
And the push rod 15 are disconnected.

When the vehicle collides, the movable member 7 retreats relative to the cowl panel 12 and separates from the cowl panel 12. However, the relative retreat distance of the movable member 7 required for this requires the switch bracket 7d. The positional relationship between the switch bracket 7d and the stopper member 6 is set such that the distance between the stopper contact portion 21 on the rear surface and the distal end surface of the stopper member 6 is slightly larger. That is, at the time of a car collision, the movable member 7
2 is removed from the stopper member 6
To come into contact with.

When the brake pedal 4 swings rearward and the brake switch 9 contacts the switch member 24 and turns on (or off), the flange 31b of the restraining member 31 disconnects and connects the movable member 7. The brake pedal 4, the movable member 7, and the connecting member 1 are positioned so as to face each other with a slight gap (see FIG. 1).
6 are determined.

The bracket 25 supporting the switch member 24 of the brake pedal 4 is an L-shaped member as shown in FIG. Member 24 is attached. The forward bending strength of the side protrusion of the bracket 25 is determined by the brake switch 9 and the switch when the brake pedal 4 swings rearward around the support shaft 13 and the brake switch 9 is turned on (or off). It is set so as to be larger than the contact load with the member 24 and smaller than the force required to detach the restraining member 31 from the collar 30.

Next, the operation of the pedal support device will be described.

When the vehicle is not in a collision, the brake pedal 4
When the pedal is depressed, it swings forward around the support shaft 13, and accordingly the push rod 15 moves forward, the stepping force is doubled by the master back 10 and transmitted to the master cylinder, and the brake pressure from the master cylinder is applied to the vehicle. The braking force is transmitted to the wheel cylinder of the wheel and acts on the wheel. When the depression force on the brake pedal 4 is released, the brake pedal 4
Is returned and the switch member 24 comes into contact with the brake switch 9 to detect that the vehicle is in the non-braking state.

When the vehicle collides with an obstacle ahead while the brake pedal 4 is depressed, the front part of the vehicle body is crushed, and the engine retreats accordingly, and is pushed by the engine, and the master cylinder, master back 10 and pedal bracket 5 are pushed. And the movable member 7 retreats to the cabin side together with the dash panel 1. Since the pedal bracket 5 and the movable member 7 are fastened to the cowl panel 12 so as to be detachable rearward, the pedal bracket 5 and the movable member 7 are separated from the cowl panel 12 by the retreat. When the movable member 7 comes off the cowl panel 12, the support shaft 13
Around the center.

When the pedal bracket 5 and the movable member 7 are further retracted together with the brake pedal 4, the movable member 7
The stopper contact portion 21 of the switch bracket 7d contacts the stopper member 6. When the push rod 15 is pushed rearward with the retraction of the master back 10 and the brake pedal 4 swings rearward, the switch member 24 of the brake pedal 4 becomes the brake switch 9 of the movable member 7.
When the stopper contact portion 21 is in contact with the
Abut. Even when the brake pedal 4 is not pushed rearward by the push rod 15, the movable member 7 is supported by the support shaft 13 when the stopper contact portion 21 hits the stopper member 6.
, The switch member 24 of the brake pedal 4 and the brake switch 9 of the movable member 7 come into contact with each other.

When the switch bracket 7d of the movable member 7 is in contact with the stopper member 6 and the switch member 24 of the brake pedal 4 is in contact with the brake switch 9 of the movable member 7, the pedal bracket 5 is further retracted.
That is, when the support shaft 13 further retreats, the bracket 25 of the switch member 24 bends forward as shown by the arrow in FIG. Thereby, as shown in FIG.
Pivots forward with respect to the brake pedal 4, that is, the connection / disconnection portion 22 of the movable member 7 moves forward and hits the flange portion 31 b of the restraining member 31 of the connection member 16. As a result, the restraining member 31 is prevented from retreating following the brake pedal 4, so that the restraining member 31 slides relatively forward and separates from the collar 30, and the connection between the brake pedal 4 and the push rod 15 by the connecting member 16. Comes off.

Therefore, the pedal bracket 5, ie,
When the support shaft 13 is further retracted, the brake pedal 4
Since the retracting of the intermediate point is prevented by the stopper member 6 via the switch bracket 7d of the movable member 7, the pedal portion 4b swings around the support shaft 13 so as to move forward, and A large collision load is prevented from acting on the foot.

In the above-described embodiment, the L-shaped bracket 25 of the switch member 24 is bent so that the switch member 24 of the brake pedal 4 and the brake switch 9 of the movable member 7 are in contact with each other. Is allowed to swing forward, in other words, the brake pedal 4 is allowed to swing backward relative to the movable member 7. Such swing allowing means is shown in FIG. What is shown can also be adopted.

The switch member 24 is supported on the side surface of the pedal arm 4a of the brake pedal 4 by urging the switch member 24 in the direction of projecting rearward by an elastic body (coil spring) 33. That is, the switch member 24 is provided at the rear end of a rod 35 extending in the front-rear direction, and the rod 35 movably penetrates front and rear flanges of a U-shaped bracket 36 having a web fixed to the side surface of the pedal arm 4a. are doing. Between the front and rear flanges of the bracket 36, a coil spring as an elastic body 33 is interposed between the spring receiver 37 fixed to the rod 35 and the front flange of the bracket 36 in a compressed state.

Accordingly, when a force equal to or more than a predetermined value acts forward, the switch member 24 moves forward against the bias of the elastic body 33. Accordingly, as in the case of the L-shaped bracket 25, the brake pedal 4 is moved rearward relative to the movable member 7 in a state where the switch member 24 of the brake pedal 4 and the brake switch 9 of the movable member 7 are in contact with each other. Swinging is allowed.

The biasing force of the elastic body 33 is applied to the brake switch 9 and the switch member 24 when the brake pedal 4 swings rearward around the support shaft 13 and the brake switch 9 is turned on (or off). Is set to be larger than the contact load and smaller than the force required to detach the restraining member 31 from the collar 30.
