The invention discloses a bidirectional return mechanism of an accelerator pedal. The bidirectional return mechanism comprises a forward pedal assembly, a backward pedal and a driving shaft; one end of the driving shaft is a forward pedal assembly, and the other end is a backward pedal; a first pull plate and a second pull plate are also sleeved on the forward pedal assembly; the first pull plateand the second pull plate are connected through a tension spring; and the advancing pedal assembly comprises a shaft hole used for being matched with the driving shaft, a pedal end on one side of theshaft hole and a shifting fork end on the other side of the shaft hole. A limiting part for limiting the pull plate to swing is arranged between the first pull plate and the second pull plate; the shifting fork end swings along with the pedal end and shifts the first pull plate or the second pull plate; the first pull plate rotates along with the forward pedal assembly, the limiting part abuts against the second pull plate, and the tension spring deforms and provides reset tension for the first pull plate; and the second pull plate rotates along with the rear pedal, the limiting part abuts against the first pull plate, and the tension spring deforms and provides reset tension for the second pull plate. According to the structure, the use of mechanical gears is reduced, and parts are reduced, so that the occurrence of problem points is reduced.

    本发明公开了油门踏板双向回位机构,包括:前进踏板总成、后退踏板、驱动轴;驱动轴的一端为前进踏板总成,另一端为后退踏板;在前进踏板总成上还套装有第一拉板和第二拉板;第一拉板与第二拉板之间通过拉簧连接;前进踏板总成包括:用于配合驱动轴的轴孔、轴孔一侧的踏板端、轴孔另一侧的拨叉端;在第一拉板和第二拉板之间设置有限制拉板摆动的限位部;拨叉端随踏板端摆动并拨动第一拉板或第二拉板;第一拉板随前进踏板总成转动,限位部顶住第二拉板,拉簧形变并提供第一拉板的复位拉力;第二拉板随后退踏板转动,限位部顶住第一拉板,拉簧形变并提供第二拉板的复位拉力。本结构减少机械档位的使用,减少零部件,以便减少问题点的发生。
