[0002] With the improvement of living standards, people's demand for vehicles has become more personalized, and multifunctional commercial vehicles with variable space have begun to enter people's field of vision. This type of vehicle can be used for business reception, ordinary families, RV modification, etc. It has good passability and huge riding space. The good passability of the vehicle is mainly due to the high height of its chassis from the ground, and the chassis is difficult to contact the raised obstacles on the ground. However, this design makes the height of the floor in the cabin higher than the ground, which is very inconvenient when getting on and off the vehicle. Since the vehicle is equipped with steps, the step board that can be extended to a moderate height from the ground and is convenient for passengers to step on improves the comfort and convenience of passengers when getting on and off the vehicle, and also improves the high-end sense of the vehicle, so the demand for car steps is gradually increasing.

[0003] In order to reduce cost and weight, some existing automotive pedals are not strong enough. When the pedals are stepped on repeatedly, they are easily damaged, resulting in poor customer feedback and affecting product sales. In addition, in order to ensure a certain strength, the structural design of the pedals is relatively complex, the pedals are unevenly processed, and they are prone to cracking.
