Problems solved by technology

[0004] In the prior art, there is a deceleration pulley on the car door crossbeam; this will not only increase the cost due to the increase of the deceleration mechanism itself, but also reduce the reliability. The position of the door motor is to avoid the interference between the motor and the top of the car. At this time, it is necessary to choose to raise the height of the car door crossbeam, or raise the height of the car door, which will increase the manufacturing and use costs.
