Abstract

An automobile sunroof adjustment mechanism comprises a motor, a gearbox body assembly and an output shaft. The gearbox body assembly comprises a box body and a transmission mechanism mounted in the box body. A motor shaft of the motor is connected to the transmission mechanism so as to drive the transmission mechanism. The transmission mechanism comprises a worm shaft, an input helical gear, a worm and an output helical gear. The worm and the output helical gear are located on different sides of the worm shaft. The present mechanism adopts a two-stage worm helical gear transmission, the two stages of worm not being self-locked, greatly reducing layout space, and the motor shaft and the output shaft are arranged in parallel, so that the mechanism can be suitable for a limited-space scenario, and has better NVH performance.
