The switching mechanism includes a guide column and a control panel. A sector gear is slidably fitted on the guide column. The sector gear has an arc-shaped groove, and a connecting rod is provided between the arc-shaped groove and the control panel. The electric drive gear and the manual drive gear have the same number of teeth. The switching is completed by the movement of the control panel, which drives the sector gear to mesh with either the electric drive gear or the manual drive gear. The calibration mechanism includes a positioning ring fixed to the electric drive gear and a positioning component connected to the control panel. Positioning holes are evenly distributed on the positioning ring. The positioning component is slidably fitted with the manual drive gear. The positioning component includes a positioning rod corresponding to the positioning holes. A positioning head is provided at the head of the positioning rod, and a spring is provided between the positioning head and the positioning rod.

[0004] Existing equipment uses a lifting motor to drive two lifting plates to achieve lifting. However, because the force application point of the lifting motor is far from the bottom horizontal of the two lifting plates, the two ends of the two lifting plates are subjected to uneven force when force is applied, causing jamming and sticking problems. Therefore, we propose an automotive window regulator to solve the above problems. Summary of the Invention
