AI Technical Summary
The gap between the bottom of the elevator car and the shaft can easily cause passengers' toes to get stuck, especially children, and current technology lacks an effective solution.
A car bottom telescopic foot protection device is designed, which uses a bidirectional telescopic drive mechanism to drive the flexible foot protection to extend and retract. The synchronous movement of the foot protection is achieved through a motor and gear assembly, and the foot protection is guided to extend or retract by rollers and gap channels to cover the gap between the car bottom and the hoistway.
It effectively prevents toes from getting stuck in the gap, improving passenger safety. At the same time, when the elevator is not in operation, the foot guards retract into the car floor, maintaining the elevator's aesthetic appearance.
