Abstract: The height of the front windshield of heavy-duty trucks is generally high. In order to facilitate the replacement of wiper blades or wiping of the windshield, there is a problem of how to set the pedal. The existing vehicle pedals ate mostly set on the bumper. The layout is simple, but the height of the pedal from the ground exceeds 650 mm, which is poor in human-machine interaction, not conducive to the use of passengers, and unsafe. To solve this problem, a flip-out and pull-out pedal is designed. When in use, the height of the pedal from the ground can be reduced to less than 500 mm. When not in use, it is retracted and hidden under the bumper, which does not take up space and does not affect the approach angle of off-road vehicles and engineering vehicles. At the same time, an anti-skid plate is set on the pedal. The width of the anti-skid plate reaches 450 mm, which provides a large standing space for both feet and is safe and convenient to use. In order to ensure that the strength and reliability of the finite element simulation technology is used for calculation and verification, the analysis results show that the structural strength meets the requirements.
