Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to a pedal bracket for a vehicle whose joint portion is bonded and fixed to the interior side surface of a dash panel and is used to support a foot pedal disposed inside the vehicle interior. Regarding support structures.

[Prior Art] A pedal bracket for supporting a foot pedal is bonded and fixed to the inside surface of an automobile dash panel (Utility Model Application No. 58-59675).

For example, the brake pedal 10 shown in FIG.
In the supporting pedal bracket 12, the dash panel 16 is sandwiched between the master cylinder 14 and fixed to the passenger compartment side surface of the dash panel 16 with bolts 18 and nuts 20, and a bearing part 12B rises from this joint part 12A. The upper end of the brake pedal 10 is rotatably attached to the brake pedal 10. In addition, with this pedal bracket 12,
The bearing part 12B is connected to the cowl 22 above the joint part 12A.
is fixed to the dash panel 16 via a bolt 24, so that no prying force is applied between the dash panel 16 and the dash panel 16 due to moment when a pedal force is applied to the brake pedal 10. Pedal bracket 12
The prying force acting between the needle and the dash panel 16 causes a loss in pedal stroke.

Therefore, in this support structure for the pedal bracket 12, when a pedal force is applied to the brake pedal 10, the darts panel 16 receives a load only in the direction perpendicular to the surface, and the darts panel 16 has rigidity in the direction perpendicular to the surface. By ensuring that
The pedal bracket support rigidity of the dash panel 16 against the pedal depression force is ensured.

However, since the dash panel 16 is generally made of a thin plate and has a structure with low rigidity, especially against loads in the direction perpendicular to the surface, the support structure for the pedal bracket 12 has a structure that is not suitable for the pedal bracket of the dash panel 16 in response to pedal depression force. In order to ensure support rigidity, it is necessary to significantly reinforce the dash panel 16 in the direction perpendicular to the surface using thick reinforcing material or the like, which causes a significant increase in cost and weight.

Furthermore, in the support structure of the pedal bracket 12, the bearing portion 12B of the pedal bracket 12 is
is fixed to the cowl 22, which is more rigid than the dash panel 16, in the longitudinal direction of the vehicle above the joint 12A, so that vehicle components (such as the engine) located in front of the dash panel 16 will be damaged in the event of a frontal collision. When the dash panel 16 or the master cylinder 14 is moved to the rear of the vehicle under the influence of the movement, the pedal bracket 12 rotates toward the rear of the vehicle around the part fixed to the cowl 22 (counterclockwise in Figure 3). ), and the brake pedal 10 may be raised toward the rear of the vehicle.

Note that if the bearing portion 12B is not fixed to the cowl 22 in the support structure for the pedal bracket 12 described above, a prying force will act between the dash panel 16 and the pedal bracket 12 due to the moment when a pedal force is applied to the brake pedal 10. Therefore, in order to ensure the pedal bracket support rigidity of the dash panel 16 against the pedal depression force, the dash panel 16 needs to be significantly reinforced in the direction of prying of the joint 12A.

Further, in this case, since the pedal bracket 12 is configured to be fixed only to the dash panel 16, when the dash panel 16 or the master cylinder 14 is moved to the rear of the vehicle in the event of a frontal collision, the pedal bracket 12 is easily moved to the rear of the vehicle due to the influence of this movement. It is also conceivable that the brake pedal 10 may be moved and the brake pedal 10 may spring up toward the rear of the vehicle.

[Problems to be solved by the invention] Taking the above facts into consideration, the present invention is capable of securing the pedal bracket support rigidity of the darts panel against pedal depression force without significantly reinforcing the darts panel, and is capable of securing the support rigidity of the foot pedal in the event of a frontal collision of the vehicle. The object of the present invention is to obtain a support structure for a vehicle pedal bracket that can prevent the pedal bracket from flying upwards toward the rear of the vehicle.

[Means for Solving the Problems] The present invention provides a support structure for a pedal bracket for a vehicle, the joint portion of which is bonded and fixed to the interior side surface of the dash panel and is used to support a foot pedal disposed inside the vehicle interior. The steering wheel is characterized in that a position below the joint portion is rotatably supported on a steering post that is disposed near the pedal bracket and is rigidly connected to the dash panel.

[Operation] According to the above configuration, when a pedal force is applied to the foot pedal, the pedal bracket apparently tries to rotate around the shaft support to the steering post that is rigidly connected to the dash panel, and a part of the pedal force is applied. The power is transmitted from this shaft support to the dash panel via the steering post. As a result, pedal depression force applied to the foot pedal is distributed to the joint of the vehicle pedal bracket and the steering post, and transmitted to the dash panel.

Therefore, it is possible to prevent pedal depression force from concentrating on the joint between the vehicle pedal bracket and the dash panel, so the pedal bracket support rigidity of the dash panel against the pedal depression force can be maintained at a high level without significantly reinforcing the dash panel. can do.

Additionally, if the dash panel is moved to the rear of the vehicle due to the impact of a frontal collision, the pedal bracket will also be moved, but the steering post will not be affected by the collision and will initially If the position is secured, the pedal bracket will be rotated around the shaft support to the steering post at a position below the joint. This prevents the foot pedal from jumping up toward the rear of the vehicle. In addition, if the area near the shaft support of the pedal bracket to the steering post is buckled under a low load, the area near the shaft support to the steering post will buckle in the event of a frontal vehicle collision, thereby preventing the foot pedal from moving rearward. As a result, it is possible to prevent the pedal from jumping up to the rear of the vehicle without applying a large impact to the steering post.

[Embodiment] FIGS. 1 and 2 show an embodiment of a support structure for a vehicle pedal bracket according to the present invention.

In this embodiment, the pedal bracket 30 is used to support a brake pedal 32. This pedal bracket 30 and the master cylinder 34 sandwich the dash panel 36 so that the bolt 3
8. It is bonded and fixed to the passenger compartment side surface of the dash panel 36 with nuts 40. In this pedal bracket 30, the joint portion 30A with the dash panel 36 is
A bearing portion 30B and a connecting portion 30C are bent at a substantially right angle toward the rear of the vehicle (toward the right in FIG. 1) from the peripheral edge of the bearing portion 30B.

The bearing part 30B is the upper part of the joint part 30A,
As shown in FIG. 2, a pair of joints are provided on both sides of the joint portion 30A in the vehicle width direction (direction perpendicular to the plane of the paper in FIG. 1), facing each other. These pair of bearing parts 30
The upper end of the brake pedal 32 is rotatably supported on B via a pin 42. A footplate 44 is fixed to the lower end of the brake pedal 32.
When the number 4 is depressed, pedal force is applied. A rod 48 is connected via a pin 46 to a vertically intermediate portion of the brake pedal 32.
One end is rotatably connected. Rod 48
The other end passes through the joint 30A of the pedal bracket 30 and the dash panel 36 and is connected to a piston (not shown) in the master cylinder 34.
The pedal force applied to the brake pedal 32 is transmitted to the master cylinder 34.

The connecting portion 30C is the lower part of the joining portion 30A, and
It is provided only on the left side of the joint portion 30A in the vehicle width direction (the front side in the direction perpendicular to the plane of the paper in FIG. 1), and is connected to the lower side of one of the bearing portions 30B on the left side in the vehicle width direction. This connecting portion 30C is the brake pedal 3
The steering post 5 is located close to the left side in the vehicle width direction of No. 2 (the front side in the direction perpendicular to the paper surface in Figure 1).
0, and its tip is provided on the steering post 50 at a position below the extension line 54 (shown in FIG. 1) of the rod 48 toward the rear of the vehicle, and further below the joint 30A. Bracket 5
2 via a pin 56 so as to be rotatable.

According to the above configuration, when the tread plate 44 is depressed and a pedal force is applied to the brake pedal 32, the brake pedal 32, the pedal bracket 30, and the master cylinder 34 are integrally moved to the first position around the pin 56.
While trying to rotate clockwise in the figure, part of the pedal force is transferred from this pin 56 to the steering post 50.
The information is transmitted to the dash panel 36 via. As a result, the pedal depression force applied to the brake pedal 32 is transferred to the joint 30A of the pedal bracket 30.
and the steering post 50, and is transmitted to the dash panel 36.

Therefore, the pedal depression force is lower than the pedal bracket 30.
Since it is possible to prevent the force from being concentrated at the joint between the joint 30A and the dash panel 36, it is possible to ensure a high level of pedal bracket support rigidity of the dash panel 36 against the pedal depression force without significantly reinforcing the dash panel 36. .

The connecting portion 30C of the pedal bracket 30 is arranged to require rigidity in the tensile direction when the pedal is operated, so the simple bending structure described above can fully demonstrate its function.

Therefore, in this embodiment, the pedal bracket support rigidity of the dash panel 36 against the pedal depression force can be ensured without significantly reinforcing the dash panel.

Furthermore, in the event of a frontal collision of the vehicle, other vehicle components may move from the front of the dash panel 36 toward the rear of the vehicle, causing the master cylinder 34 and the dash panel 36 to move toward the rear of the vehicle.
If the steering post 50 moves toward the rear of the vehicle under the influence, the pedal bracket 30 will also be moved under the influence, but the steering post 50
If the pedal bracket 30 is not affected by the collision and maintains its initial position, the pedal bracket 30 will be rotated clockwise in FIG. 1 about the pin 56 located below the joint portion 30A. Furthermore, even if the steering post 50 moves toward the rear of the vehicle due to the impact of the collision, and the master cylinder 34 and the dash panel 36 are not affected by the collision, the pedal bracket support rigidity of the dash panel against the pedal depression force remains unchanged as in the conventional case. Since the cowl structure does not require support to ensure that the pedal bracket 3
0 is pulled by the steering post 50 and moves toward the rear of the vehicle, but it is difficult to rotate around the upper part. Therefore, even if the pedal bracket 30 is moved under the influence of a frontal collision of the vehicle, at least the brake pedal 32 will not be rotated in the direction in which it springs up rearward, and thereby the brake pedal 32 will not be moved rearward. Splashing is prevented. Note that if the connecting portion 30C is made to buckle under a low load, the rearward movement of the brake pedal 32 will be absorbed by the buckling of the connecting portion 30C in the event of a frontal collision of the vehicle. , it is possible to prevent the brake pedal 32 from jumping rearward without applying a large impact to the steering post 50. In this case, the needle panel 3
6. This is suitable in cases where it is disadvantageous in terms of ensuring safety to have the influence of rearward movement of the pedal bracket 30 exerted on the steering post 50.

[Effect of the invention] As explained above, in the support structure for a vehicle pedal bracket according to the invention, the position below the joint of the pedal bracket is located near the pedal bracket and is connected to the steering post which is rigidly connected to the dash panel. Since the shaft is rotatably supported, it is possible to ensure the support rigidity of the foot pedal against the pedal depression force without significantly reinforcing the foot pedal, and also to prevent the foot pedal from flying up to the rear of the vehicle in the event of a frontal collision. have an effect.
