AI Technical Summary
Technical Problem
The transmission gears of the window regulator are prone to coming loose, causing the window to malfunction.
Method used
A car window lifting device was designed, wherein one end of the rotating shaft is embedded in the side wall of the housing through a stop block and is sleeved on the rotating shaft with a worm gear. When the worm gear moves axially, it abuts against the cover to prevent the gear from falling off. The rotating shaft is fixed to the gearbox to ensure normal lifting of the car window.
Benefits of technology
This effectively prevents the shaft and worm gear from falling off, ensuring the stable operation of the window lifting device, avoiding the problem of gear falling off, and guaranteeing the normal lifting function of the window.
