JP4300935B2 - Control pedal reverse control structure for vehicle - Google Patents

Description

  The present invention relates to a support structure for a vehicle operation pedal.

  Currently, in an actual vehicle collision test on a vehicle, the amount of retraction of the operation pedal is listed as an evaluation item as a guideline for an injury level of an occupant's lower limb. This is because there is a case where the operation pedal enters the occupant side when the vehicle collides with the front and is injured by interfering with the limb of the occupant.

4 and 5 show many of the conventional vehicular operating pedal reverse control structures that are employed.
FIG. 4A is a schematic side view of an example of a conventional operation pedal support structure, and FIG. 4B is a schematic side view showing the state of the operation pedal after a frontal collision of the vehicle.

  The operation pedal 103 is supported via a bracket 102 attached to the indoor side of the dash panel 101. A sled (curved member) 105 is installed on a deck cloth 104 extending in the vehicle width direction behind the bracket 102. When a vehicle (not shown) collides with the front, the dash panel 101 moves backward with respect to the vehicle, and the end 102a of the bracket 102 contacts the sled 105. When the dash panel 101 is further retracted, the lower portion 102b of the bracket 102 is broken, and the bracket 102 is deformed so that the end portion 102a is bent downward. Thereby, the reverse amount of the operation pedal 103 is reduced.

  5A is a schematic side view of another conventional operation pedal support structure, and FIG. 5B is a schematic perspective view showing a state in which the operation pedal is attached to the bracket. (C) is the schematic perspective view which showed the mode of the operation pedal after the front collision of a vehicle.

  An operation pedal 103 is supported via a bracket 106 attached to the interior side of the dash panel 101. The operation pedal 103 is attached by inserting a boss portion 103a into an opening hole 106b formed in the central portion of the side surface 106a of the bracket 106. A rigid member 107 is installed on a deck cloth 104 extending in the vehicle width direction on the vehicle rear side of the bracket 106. When a vehicle (not shown) collides with the front, the dash panel 101 moves backward, and the end 106c of the bracket 106 contacts the rigid member 107. When the dash panel 101 is further retracted, the side surface 106a of the bracket 106 expands in the vehicle width direction. Therefore, since the operation pedal 103 falls downward, it corresponds to the problem that the operation pedal moves backward during a vehicle front collision.

  Another example of the prior art is disclosed in Japanese Patent Laid-Open No. 10-297400. This publication describes a vehicle pedal support structure that can control the displacement of the tread surface of a vehicle pedal when an external force of a predetermined value or more acts from the front of the vehicle.

JP-A-10-297400

  In the case of the prior art shown in FIG. 4 described above, the pedal bracket 102 is brought into contact with the sled 105 and is deformed downward in the vehicle. However, the deformation is not always constant, and the deformation is stable. There is a problem that lacks sex. Further, when machining such as a slit is applied to the pedal bracket 102 to ensure the stability of deformation, a new problem of requiring a further processing man-hour occurs. In the case of the other prior art shown in FIG. 5, the pedal bracket 106 needs to be drilled, processed to expand the side surface in the vehicle width direction, and the like. . In addition, the operation pedal 103 may not fall depending on the retraction amount of the dash panel 101.

  In the prior art disclosed in Japanese Patent Laid-Open No. 10-297400, the members constituting the bracket are side plates, back plates, mounting members, and bridging members, and the back plate is another member constituting the bracket. It must be made of a material with high rigidity different from Further, the back plate needs to be machined to form grooving or flange processing. Therefore, if the number of members constituting the bracket is large, there is a problem that the processing is very laborious and the cost is high.

  From the above problems, it is considered to be a good idea to reliably control the operation pedal using a simplified and inexpensive structure. Therefore, the present invention is for a vehicle that can reduce the injury to the occupant's lower limbs by controlling the retreat amount of the operation pedal, that is, the movement amount to the occupant side, when an external force exceeding a predetermined value acts on the front part of the vehicle. An object of the present invention is to provide a control pedal reverse control structure.

A vehicular operation pedal reverse control structure according to a first aspect of the present invention for solving the above problems is as follows.
A vehicle body structural member that is displaced rearward when an external force of a predetermined value or more is applied to the front of the vehicle;
A bracket connected to the vehicle interior side of the vehicle body component;
One end of which is rotatably supported on both sides of the bracket, a rotary shaft extending in the vehicle width direction,
An operation pedal supported on the other end of the rotating shaft;
The fixed to the rotary shaft, located between both sides of the bracket, and a rocking member which extends in the vertical direction of the vehicle,
When retraction of the vehicle body structure member, the swinging member by contacting the vehicle body rigidity member, characterized in that so as to swing the operating pedal to the vehicle both forward.

A vehicular operation pedal reverse control structure according to a second invention for solving the above-mentioned problems is as follows.
In the vehicle operation pedal reverse control structure according to the first invention ,
The vehicle body rigid member is a strut house.

  According to the vehicular operation pedal retraction control structure according to the present invention, the swinging member is brought into contact with the strut house, and the operation pedal is rotated forward together with the swinging member, so that the operation pedal can be reliably retracted. The amount can be controlled. In addition, since the operation pedal that has been rotated once does not return to the rear of the vehicle, it is safe for passengers. Further, the abutting surface of the swing member and the strut house may be formed in a curved shape, and since the strut house is a rigid member, the swing member can be smoothly rotated forward of the vehicle. It is possible to control the retraction amount of the operation pedal. Therefore, since there is no complicated configuration, the number of parts is small and no cost is required. Space for passengers can be widened.

A vehicle operating pedal retreat control structure according to the present invention will be described in detail based on an embodiment.
FIG. 1 shows a side view of a vehicular operating pedal retreat control structure according to an embodiment of the present invention, and FIG. 2 shows a front view seen from the passenger compartment side of FIG.

  A headlamp support 2, which is a vehicle body component, is installed in front of the passenger compartment 1a. A support bracket 4 is installed on the side of the cabin 1a of the headlamp support 2 via a reinforcement 3 that is a reinforcing material. The support bracket 4 is attached to the phosphorus hose 3 with a bolt 5, and the reinforcement 3 is attached to the headlamp support 2 by welding or the like.

  The support bracket 4 has a front wall 4a and side walls 4b and 4c at both ends thereof, and a rotating shaft 6 extending in the vehicle width direction is rotatably supported by the side walls 4b and 4c. Further, a right end portion (right end portion viewed from the vehicle interior side) 6a of the rotating shaft 6 is rotatably supported on the vehicle body right side surface 1b. A brake pedal 7 including an arm portion 7a and a pedal portion 7b is fixed to the left end portion 6b of the rotating shaft 6. A lever 8, which is a swing member, is attached to a portion 6 c of the rotating shaft 6 sandwiched between the side walls 4 b and 4 c of the support bracket 4.

  A strut house 9 that is a vehicle body rigid member is disposed below the lever 8. The pressing portion 8 a at the lower end of the lever 8 is positioned so as to face the end portion 9 a of the strut house 9. The pressing portion 8a and the end portion 9a are formed in a curved surface shape.

  Therefore, when the occupant decelerates or stops the vehicle, the occupant first tries to step on the pedal portion 7b of the brake pedal 7. The depressed brake pedal 7 rotates forward of the vehicle together with the rotating shaft 6 attached to the arm portion 7a. At this time, since the lever 8 is connected to the brake pedal 7 via the rotating shaft 6, the lever 8 rotates forward of the vehicle in the same manner as the rotating shaft 6 and the brake pedal 7. That is, the brake pedal 7 and the lever 8 are integrated and rotate together.

  FIG. 3 is a side view showing a state in which an external force of a predetermined value or more is applied to the front of the vehicle in the vehicle having the vehicle operation pedal reverse control structure according to the embodiment of the present invention. A part of the side wall 4b of the support bracket 4 is cut away.

When an external force of a predetermined value or more is applied to the front of the vehicle, the headlamp support 2 moves to the rear of the vehicle due to deformation of the vehicle body. Further, the bracket support 4 installed on the headlamp support 2 also moves to the rear of the vehicle via the reinforcement 3. Accordingly, the brake pedal 7 and the lever 8 supported by the bracket support 2 via the rotating shaft 6 also move rearward of the vehicle.

  The pressing portion 8 a of the lever 8 that has moved to the rear of the vehicle contacts the end portion 9 a of the strut house 9. When the lever 8 further moves rearward of the vehicle, the pressing portion 8a presses the end portion 9a. At this time, since the Stutthouse 9 is higher in rigidity than the lever 8, in any case, when an external force of a predetermined value or more is applied to the front of the vehicle, the pressing portion 8a does not deform the end portion 9a with almost no deformation. Press.

  For this reason, the movement of the lever 8 to be moved is blocked by the strut house 9 which is a rigid member, and only the headlamp support 2 and the brake pedal 7 move to the rear of the vehicle. Thereafter, the lever 8 starts to rotate forward of the vehicle as if the pressing portion 8a is being pressed. Since the pressing portion 8a and the end portion 9a are formed in a curved surface shape, the lever 8 can be rotated forward of the vehicle without difficulty. The state of rotation is indicated by arrows in FIG.

  Since the lever 8 rotates, the brake pedal 7 connected via the rotating shaft 6 also rotates forward in the same manner as the lever 8. Thereby, the amount of backward movement of the brake pedal 7 to the vehicle can be controlled.

According to the structure as described above, the pressing portion 8a of the lever 8 is brought into contact with the end portion 9a of the strut house 9, and the lever 8 is rotated forward of the vehicle to rotate the brake pedal 7. This is the same as when the occupant steps into the pedal portion 7b of the brake pedal 7. Since this is an operation often performed when an occupant operates the pedal, the forward rotation of the brake pedal 7 is stable and reliable in the operation, so that the amount of reverse movement of the brake pedal 7 is ensured. Can be controlled. Also, once the brake pedal 7 has been rotated, the pressing portion 8a of the lever 8 is in contact with the end portion 9a of the strut house 9, and therefore cannot be rotated rearward of the vehicle. It is safe for passengers.

  Further, since the pressing portion 8a and the end portion 9a are formed in a curved shape and the strut house is a rigid member, the lever 8 can be smoothly rotated forward of the vehicle, and the The reverse amount of the brake pedal 7 can be controlled.

  Furthermore, since it does not have a complicated configuration, the number of parts is small and no cost is required. Space for passengers can be widened.

  By mounting such a vehicle operating pedal support structure on a vehicle, the injury level of the occupant's lower limb can be reduced.
