Description

The present invention relates to a pedal support structure that supports a pedal in a vehicle.

Conventionally, a pedal support structure for supporting a pedal such as a brake pedal in a vehicle is known. Here, when a vehicle collides, the pedal may move to the rear side of the vehicle, that is, the passenger side together with the front portion of the vehicle due to the impact at that time.

Therefore, a technique has been proposed in which the pedal support shaft, which is the center of rotation of the pedal during normal operation, is moved to the lower side of the vehicle in the event of a vehicle collision, thereby suppressing the amount of movement of the pedal toward the passenger side ( See, for example, Patent Document 1.). In the technique described in Patent Document 1, a member that comes into contact with a vehicle member at the time of a collision is provided. The pedal support shaft is moved by transmitting the contact force of this member to the vehicle member to the pedal support shaft.

The bracket 12 includes a pair of opposing walls 121. As described above, the pedal support shaft 11, which is a bolt, penetrates the one opposing wall 121, the boss 23 of the brake pedal 2, and the other opposing wall 121, and the nut 14 is fastened to the tip thereof. ing. The nut 14 is fastened so that the brake pedal 2 can rotate around the pedal support shaft 11.

A support shaft moving member 13 is connected to an end of the bracket 12 on the rear side of the vehicle. The support shaft moving member 13 is arranged between the opposing walls 121 on one side. Then, the pair of side walls 131 of the support shaft moving member 13 is caulked and fixed to the pair of opposing walls 121 of the bracket 12 by the pair of pins 122. Each pin 122 is crimped so that the side wall 131 of the support shaft moving member 13 is rotatable around the center of the pin 122 with respect to the facing wall 121 of the bracket 12. Accordingly, the support shaft moving member 13 is connected to the bracket 12 so as to be rotatable about the line connecting the centers of the pair of pins 122 as the rotation center 13a. The rotation center 13a is located on the rear side of the vehicle substantially parallel to the pedal support shaft 11.

The support shaft moving member 13 includes a pair of side walls 131 and a rear wall 132 that connects the rear side edges of the vehicle of the pair of side walls 131, and is formed in a substantially U shape in a top view. The ends of the pair of side walls 131 on the front side of the vehicle form a connecting portion 131a connected to the pedal support shaft 11.

The connecting portion 131a is located on the front side of the vehicle with respect to the rotation center 13a of the support shaft moving member 13, and is connected to the pedal support shaft 11 by penetrating the pedal support shaft 11. Further, the connecting portion 131 a is sandwiched between the boss 23 of the brake pedal 2 and the facing wall 121 of the bracket 12. The pedal support shaft 11 as a bolt and the nut 14 are fastened together with the boss 23 to the facing wall 121.

Here, in the present embodiment, the pipe-shaped vehicle member 5 as a steering member is arranged further away from the rear wall 132 on the rear side of the rear wall 132 of the support shaft moving member 13. At this time, when the vehicle collides, the pedal support structure 1 may move to the rear side of the vehicle together with the dash panel 3. The vehicle member 5 is a member in which the amount of movement of the vehicle toward the rear side at the time of a collision is smaller than that of the dash panel 3. Therefore, at the time of a collision, the rear wall 132 of the support shaft moving member 13 contacts the vehicle member 5. That is, the rear wall 132 of the support shaft moving member 13 is a contact portion that is on the rear side of the vehicle with respect to the rotation center 13a and that contacts the vehicle member 5 on the further rear side of the vehicle when the vehicle collides. .. Then, the rear wall 132 as an abutting portion abuts on the vehicle member 5 at the time of a collision, thereby moving the connecting portion 131a around the rotation center 13a in the direction of the arrow D1 to move the pedal support shaft 11 to the lower side of the vehicle. Play a role in moving. By the movement of the pedal support shaft 11, as described above, the brake pedal 2 is lowered as a whole and the pedal tread 21 is moved to the front side of the vehicle.

FIG. 5 is a view showing the support shaft moving member shown in FIGS. 1 to 4. Similar to FIG. 4, FIG. 5A shows a perspective view of the support shaft moving member 13 viewed from the front side of the vehicle. FIG. 5B shows a side view of the support shaft moving member 13 as seen from the arrow V1 in FIG. 5A.

As described above, the support shaft moving member 13 includes the pair of side walls 131 and the rear wall 132, and the end of the side wall 131 on the rear side of the vehicle serves as the connecting portion 131a of the pedal support shaft 11, and the rear wall 132 collides. It is an abutting portion that abuts the vehicle member 5 at times. The pair of side walls 131 oppose each other in the vehicle width direction D2 of the vehicle with the pair of bosses 23 provided on the other end 222 side of the pedal arm 22 (FIG. 1) interposed therebetween. The connecting portion 131a of each side wall 131 is provided with a through hole 131a-1 through which the pedal support shaft 11 as a bolt penetrates. Further, a through hole 131b through which the pin 122 (FIGS. 3 and 4) forming the rotation center 13a penetrates is provided on the rear side of the vehicle in each side wall 131 with respect to the connecting portion 131a.

Here, in the present embodiment, the pedal support shaft 11 is located on the lower front side of the vehicle with respect to the rotation center 13a at a time point before the collision, that is, at the normal time, and the rear wall 132 serving as the contact portion is formed. It is arranged on the upper rear side of the vehicle. The mutual distance d1 between the pedal support shaft 11 and the rotation center 13a is shorter than the mutual distance d2 between the rear wall 132 as the contact portion and the rotation center 13a.

Further, the supporting shaft moving member 13 has a substantially L-shaped side view shape in the vehicle width direction D2 of the vehicle as shown in FIG. 5(B). The rear wall 132 corresponding to the rear side of the vehicle in the portion forming the vertical line in the substantially L-shape forms the contact portion.

In the pedal support structure 1 of the present embodiment described above, the support shaft moving member 13 that moves the pedal support shaft 11 in the event of a vehicle collision is provided with the connecting portion 131a connected to the pedal support shaft 11. Then, at the time of a collision, the rear wall 132 as an abutting portion abuts on the vehicle member 5, thereby moving the connecting portion 131a around the rotation center 13a to move the pedal support shaft 11. Accordingly, at the time of a collision, the contact force of the support shaft moving member 13 with the vehicle member 5 is directly transmitted to the pedal support shaft 11. Therefore, according to the pedal support structure 1 of the present embodiment, the amount of movement of the brake pedal 2 toward the occupant can be sufficiently suppressed regardless of the deformation of the vehicle at the time of a collision. Further, since the load when the vehicle member 5 is brought into contact with the vehicle is received by the rear wall 132 of the support shaft moving member 13, which is on the rear side of the vehicle, the rotational moment around the rotation center 13a is high. Also in this respect, the amount of movement of the brake pedal 2 can be sufficiently suppressed.

Further, in the present embodiment, the mutual distance d1 between the pedal support shaft 11 and the rotation center 13a is shorter than the mutual distance d2 between the rear wall 132 as the contact portion and the rotation center 13a. Therefore, the contact force to the vehicle member 5 is amplified by the lever principle and transmitted to the pedal support shaft 11. As a result, the pedal support shaft 11 can be moved with a strong force, so that the amount of movement of the brake pedal 2 toward the occupant can be reliably suppressed.

Further, in the present embodiment, the support shaft moving member 13 has a structurally reinforced shape having a pair of side walls 131 and a rear wall 132. As a result, the deformation of the support shaft moving member 13 at the time of contact with the vehicle member 5 at the time of collision is suppressed, so that the contact force at that time is sufficiently transmitted to the pedal support shaft 11. As a result, the amount of movement of the brake pedal 2 toward the passenger can be reliably suppressed.

Further, in the present embodiment, since the rear wall 132 corresponding to a portion that forms a vertical line in the substantially L-shape, that is, a portion that extends in the vertical direction of the vehicle forms an abutting portion, it hits the vehicle member 5 at the time of a collision. It is easy to contact. This increases the accuracy of contact with the vehicle member 5 at the time of a collision, and as a result, the amount of movement of the brake pedal 2 toward the occupant can be reliably suppressed. Further, with this configuration, even if the deformation at the time of collision is not a deformation that goes straight to the rear side but a deformation that pushes up diagonally upward, there is no concern that it will not come into contact, and the rotation The decrease in moment is also suppressed.

Further, in the present embodiment, the planar portion of the rear wall 132 is configured to contact the vehicle member 5. Therefore, it is possible to avoid the situation where the load pressure is concentrated at the time of contact and the vehicle member 5 is deformed and the contact is disengaged. Further, even if the rear wall 132 comes into contact with the vehicle member 5 in an inclined state in the vehicle width direction, the abutting state is corrected so that it comes into contact with the vehicle member 5, so that the abutting fails. Is avoided.

Further, in the present embodiment, the support shaft moving member 13 is connected to the bracket 12 by crimping and fixing using the pin 122. As a result, the amount of exposure at the connecting portion is suppressed. Therefore, even if the pedal support structure 1 is deformed due to a load caused by a collision or an abutment with the vehicle member 5, a situation in which the connecting portion interferes with the support shaft moving member 13 and inhibits its rotation, etc. It can be suppressed. In addition, since high connection strength can be obtained by crimping and fixing, the connection state can be sufficiently maintained even when the load due to collision or contact with the vehicle member 5 is large.

The above-described embodiment merely shows a typical form of the present invention, and the present invention is not limited to this embodiment. That is, various modifications can be made without departing from the gist of the present invention. As long as the modification still has the structure of the pedal support structure of the present invention, it is of course included in the scope of the present invention.

For example, in the above-mentioned embodiment, the brake pedal 2 is illustrated as an example of the pedal according to the present invention. However, the pedal according to the present invention is not limited to this. The pedal according to the present invention may be, for example, an accelerator pedal or the like as long as the pedal tread is provided at one end of the pedal arm, and its specific aspect is not limited.

Further, in the above-described embodiment, the pipe-shaped vehicle member 5 serving as the steering member is illustrated as an example of the vehicle member according to the present invention. However, the vehicle member referred to in the present invention is not limited to this, and any specific embodiment thereof is acceptable as long as it is a member that is on the rear side of the contact portion of the support shaft moving member and can contact the support member. ..
