Anti-pinch structure of electric seat
By incorporating a retractable footrest support assembly and an angle sensor into the electric seat, the problem of the footrest getting stuck on obstacles when retracting is solved. This allows the footrest to stop or reverse its movement when an obstacle is detected, preventing injury.

AI Technical Summary
Technical Problem
Existing power seats may trap obstacles when the footrest or footstool is retracted, posing a potential injury.
Method used
An anti-pinch structure for an electric seat was designed, including a retractable footrest support assembly and an angle sensor for detecting changes in the angle of the footrest assembly and stopping or reversing the movement of the footrest when an obstacle is detected.
Benefits of technology
By detecting changes in the angle and pressure of the footrest assembly, the system prevents the footrest from getting caught on obstacles, thus avoiding injury to the user or nearby personnel.

Abstract
The utility model belongs to the technical field of electric seats, and particularly relates to an electric seat anti-pinch structure which comprises a seat frame assembly, a foot rest supporting assembly, a foot rest assembly, an angle sensor, a shell and a base. The shell is arranged on the base, and the seat frame assembly is connected to the shell; the foot rest support assembly is telescopically connected to the seat frame assembly; the foot rest assembly is rotationally connected to the far end of the foot rest supporting assembly. The angle sensor is arranged on the foot rest assembly. The telescopic foot rest supporting assembly is arranged to drive the foot rest assembly to stretch out and draw back, the angle sensor is arranged to be used for detecting the angle change of the foot rest assembly from the horizontal state to the vertical state before the foot rest assembly touches the seat frame assembly, and it is indicated that the foot rest assembly touches the foreign matter. Therefore, when the existence of the obstacle is detected, the electric seat can stop the movement of the telescopic foot rest supporting assembly, and the anti-pinch effect is achieved.
