AI Technical Summary
The existing structure of the car chassis testing and debugging pit lacks a closing function when not in use, which poses a safety hazard to workers.
A servo motor drives the rotating shaft, which in turn drives the turntable and linkage mechanism, causing the moving bar to push the pedal to slide inside the entrance, thereby closing the pit. A transparent plastic film is also provided to prevent debris from falling on the staff.
The system enables the pit to close automatically when not in use, preventing workers from accidentally stepping on it, reducing safety hazards, and using a transparent membrane to prevent debris from falling in, thus improving work safety.
