The operating principle of the step structure is explained as follows:

when a driver presses down to turn on a power supply, a sound and light alarm is sent to prompt passengers near a passenger door to pay attention to avoiding the pedal, meanwhile, the first motor starts to work to enable the transmission belt to rotate anticlockwise, the sliding piece is riveted on the transmission belt, and the transmission belt drives the pedal to slide outwards; when the pedal moves outwards to the position of the proximity switch, the proximity switch is touched, and the first motor stops working; at the moment, the pedal protrudes out of the vehicle body, and the pedal slowly rotates downwards around the hinge under the action of the damping rod; the pedal is fully open. The front end of the pedal is an inclined plane, the joint is smooth and has no steps; the wheelchair is smooth in the operation process and free from pause and contusion caused by steps.

The working principle of pedal retraction is as follows: when a driver presses down to withdraw the power supply, a sound-light alarm is sent to prompt passengers near a passenger door to pay attention to avoiding the pedal, and meanwhile, the first motor starts to work to drive the sliding piece and the pedal to be withdrawn into the frame; when the sliding piece touches another proximity switch, the first motor stops working; the pedals are fully retracted.

The manual operation principle is as follows:

the unlocking switch is pressed, and the first motor is separated from the transmission belt under the action of the linear motion part; the pedal can now be pulled out manually. When the pedal is manually retracted, the pedal is retracted inwards, and when the sliding piece touches the proximity switch, the linear motion part works to enable the first motor to move and be meshed with the transmission belt, so that the locking and limiting of the pedal are realized.

The peripheral section bar of the step structure provided by the invention is in a lap joint mode with the floor and the plastic flooring, so that the floor and the plastic flooring are pressed under the section bar to avoid the failure of the plastic flooring at the position due to long-term treading and overturning; the pedal one-key starting function is realized by configuring the motor and the damping rod, and the pedal one-key starting function is integrated manually and automatically, so that the operation is more convenient and faster; the surface of the pedal is not required to be adhered with floor leather, and the pedal is formed at one step, is wear-resistant and anti-skid; the surface is flush with the floor in the vehicle, and the trafficability characteristic is good; the pedal section bar and the floor are in a lap joint mode, and the floor and the plastic flooring are assembled below the section bar, so that the risk of failure of a butt joint type plastic flooring welding rod is avoided; the pedal is in a drawing type, so that automatic drawing and pulling can be realized, manual and automatic integration can be realized, and the operation is convenient and fast; the surface of the pedal does not need to be paved with floor leather, and the pedal is wear-resistant, skid-resistant and good in trafficability.
