Abstract

PROBLEM TO BE SOLVED: To provide an accelerator pedal in which a flexible part provided between a pedal body and a stationary part has good flexibility and the accelerator pedal itself may be manufactured inexpensively. SOLUTION: According to this accelerator pedal, at the flexible part 12, an outer groove 16 formed adjacent each hinge part 15 digs down sides of the hinge part 15 so that the hinge part 15 may be bow-shaped, thereby increasing a deformable range, compared with a conventional flat hinge structure. Thus, the flexible part 12 may absorb large bent distortion. Further, the flexible part 12 is thus constructed to be an easily flexible structure and therefore may be made of less costly olefin resins (polypropylene, for example).

By the way, in the conventional accelerator pedal, V-shaped grooves 4A, 4A are formed at the same positions on the front and back of the bent portion 2, and a flat wall portion sandwiched between these grooves 4A, 4A is formed. The hinge portion 4 was constituted by. For this reason, the conventional hinge portion 4 has to absorb the bending strain with a short length in which the shortest distance between the thick portions 5 and 5 is linearly connected. Then, when the pedal body 1 is stepped on and the bending of the bending portion 2 deepens, the amount of distortion of each hinge portion 4 becomes large, and the hinge portion 4 may not return to its original state. In particular, in order to reduce the cost, when polypropylene is used instead of the conventional polyester resin as the member forming the accelerator pedal, the flexibility is lowered, and the above-mentioned situation is likely to occur.

Further, when the bent portion 2 is bent, the central portion of the bent portion 2 receives a larger bending stress than the end portion of the bent portion 2, but in the conventional case, a plurality of hinges included in the bent portion 2 are provided. Since the parts 4 all have the same structure (specifically, the same second moment of area), the amount of strain applied to the central hinge part 4 is larger than that of the other hinge parts 4, and each hinge part 4 has a larger distortion amount. The amount of distortion was out of balance.

In order to attach the accelerator pedal to the vehicle body, first, the fixing portion 13 is screwed to the floor surface of the driver's seat of the vehicle body. Next, the pedal body 11 is tilted to the fixing portion 13 side, and the tip end portion of the accelerator lever 51 is rotatably fixed to the pedal body 11 with a pin (not shown). When the pedal body 11 is tilted to the fixed portion 13 side, it is bent to the bent portion 12. Here, in the bent portion 12, the bending stress applied to the bent portion 12 increases from the both end sides toward the center side, but in the present embodiment, from the hinge portion 15 on both end sides of the bent portion 12 to the center side hinge portion. As the second moment of area of each hinge portion 15 is increased toward 15, the balance of the strain amounts of the plurality of hinge portions 15 is improved, and when the accelerator pedal is attached to the vehicle body, as shown in FIG. And all hinge parts 1 as shown in FIG.
5 is evenly bent, and the entire bent portion 12 is curved in an arc shape.

When the pedal body 11 is stepped on by the driver, the bending portion 12 is bent with a larger force. Here, in the accelerator pedal of the present embodiment, in the bent portion 12,
By the outer groove 16 formed adjacent to each hinge portion 15, the side of the hinge portion 15 is dug down, and the hinge portion 1
5 has a curved shape, and the deformable range becomes longer than that of the conventional flat hinge structure. Thereby, each hinge part 1
5 can absorb a large bending strain. Moreover, since the hinge portion 15 and the outer groove 16 are smoothly continuous, stress concentration can be prevented. In addition, since the second moment of area is made different for each hinge portion 15 as described above, the strain amount is well balanced and distributed to each hinge portion 15 even when a strong bending force is applied. As described above, the durability of the bent portion 12 is improved as compared with the conventional one, and the bent portion 12 is restored to the original state even if the bending operation of the bent portion 12 is frequently repeated.

Further, since the bent portion 12 is formed with a thick portion 17 having a thickness larger than that of the hinge portion 15 between the adjacent hinge portions 15, these thick portions 17 are used. The twisting strength of the bent portion 12 can be ensured.
Furthermore, since the accelerator pedal of the present embodiment is made of an olefin resin (specifically, polypropylene), it can be manufactured at a lower cost than that of a conventional polyester resin.

As described above, in the accelerator pedal of this embodiment, the hinge portion 15 has a curved shape, and the deformable range is longer than that of the conventional flat hinge structure. Therefore, a large bending strain is generated at the bending portion 12. Can be absorbed. Further, since the bending portion 12 is structurally easily bendable in this way, it becomes possible to manufacture the olefin resin at a low cost.
