[0002] The trunk of a pickup truck is higher than the ground, so a pedal is usually set at the trunk position for users to step on and move goods into the trunk. Currently, the pedal is mainly fixed with a bracket + bolt structure. The disadvantage is that the car pedal is fixed at the door sill position for a long time and occupies a lot of space when not in use. There is also a pin connection structure, which has the disadvantages of being overall thick and heavy, difficult to position, and large fluctuations in the range of motion of the motion axis. Summary of the invention

[0003] The purpose of the present invention is to provide a car pedal which saves structural space, is convenient for positioning, and avoids the movement axis on the pedal from deviating from the movement track when swinging due to the unstable connection of a single metal pin.

[0008] The rotation of the first moving shaft and the second moving shaft drives the upper pedal and the lower pedal to expand or fold each other, and the torsion spring is a reset mechanism of the first moving shaft. The torsion spring always generates an upward elastic force to push the first moving shaft closer to the upper pedal, and the second moving shaft, the lower pedal and the first moving shaft are linked to move closer to the upper pedal, so that in the initial state, the first moving shaft, the second moving shaft, the lower pedal and the first moving shaft are always close to the upper pedal to maintain a folded state, and the torsion spring always generates an upward spring to prevent the upper moving shaft of the pedal from loosening or making abnormal noises due to the unstable connection of a single metal pin, thereby improving the stability of the car pedal.

[0035] How it works

[0036] Expand car pedal

[0037] The car pedal is installed at the rear of the pickup truck. When the user presses down the pressing part 91 with his foot, the torsion spring 5 is deformed, and the pedal 2 moves downward to overcome the elastic force of the torsion spring 5 and drives the first motion shaft 3 and the second motion shaft 4 to rotate downward.

[0038] The first moving shaft 3 rotates, the first moving shaft 3 overcomes the elastic force of the elastic protrusion 62, the elastic protrusion 62 leaves the first concave hole 31, and the first moving shaft 3 is separated from the first positioning cavity 63.

[0039] Until the upper pedal 1 is located at the upper end of the first motion axis 3 and the second motion axis 4, and the lower pedal 2 is located at the lower end of the first motion axis 3 and the second motion axis 4, the car pedals are fully unfolded so that the upper pedal 1 and the lower pedal 2 form a step. The user first steps on the stepping part 9 of the lower pedal 2, and then steps on the upper pedal 1 to enter the trunk. The operation is simple.

[0040] Folding car pedal

[0041] When the user leaves the car pedal, the torsion spring 5 is reset, and the torsion spring 5 drives the first motion shaft 3 to rotate upward, while the second motion shaft 4 rotates upward following the first motion shaft 3 .
