The invention discloses a plastic accelerator pedal-rod structure which comprises an installation seat, a rocker arm and a pedal body. A y-shaped rib composed of a fourth strip-shaped rib and a fifth strip-shaped rib and an x-shaped rib composed of a second strip-shaped rib and a third strip-shaped rib are arranged at the end portion, close to the installation seat, of the rocker arm, the upper end of the fourth strip-shaped rib and the upper end of the fifth strip-shaped rib are connected with an upper plate respectively, the lower end of the fourth strip-shaped rib is connected with the middle of the fifth strip-shaped rib, and the lower end of the fifth strip-shaped rib is connected with a lower plate. The upper end of the second strip-shaped rib is connected with the intersection of the fourth strip-shaped rib and the fifth strip-shaped rib, a boss is arranged at the left portion of the installation seat, the upper end of the third strip-shaped rib is connected with the boss, and the lower end of the second strip-shaped rib and the lower end of the third strip-shaped rib are connected with the lower plate respectively. A first strip-shaped rib is arranged between the y-shaped rib and the x-shaped rib, the left end of the first strip-shaped rib is connected with the connection point of the lower end of the fifth strip-shaped rib and the lower plate, and the right end of the first strip-shaped rib is connected with the connection point of the lower end of the third strip-shaped rib and the lower plate. The plastic accelerator pedal-rod structure is reasonable in stress and long in service life.
Description
technical field [0001] The invention belongs to an automobile accelerator pedal, in particular to a plastic accelerator pedal rod structure. Background technique [0002] Under the threat of energy crisis and the requirements of environmental protection, the automobile industry is making various efforts for energy saving and emission reduction of automobiles. At present, more and more electronic accelerator pedals have replaced traditional mechanical accelerators. At the same time, based on cost and lightweight considerations, electronic accelerator pedals are made of plastic injection molding. In addition to meeting the requirements of space and shape, the plastic accelerator pedal must also meet certain strength requirements to ensure that the pedal can provide sufficient strength to prevent the accelerator pedal from being broken or deformed during driving, which will affect its use. [0003] Such as figure 1 As shown, the existing plastic gas pedal rod includes a mount...
