Problems solved by technology

Because the crank-type manual lifting method occupies a large space in the car and is not beautiful, many car door and window glass lifting (closing and opening) have abandoned the manual lifting method and switched to the button-type electric lifting method, that is, using electric glass lift

However, the electric window lifter has the following disadvantages: Once the motor fails or the button controlling the motor fails, the battery power is low, or the control circuit fails, the door and window glass will not be able to perform any lifting operations

In case of rainy and snowy weather, driving at high speed, or parking, the window cannot be closed, which will bring great inconvenience to the owner or even a safety hazard; especially if the car accidentally falls into the water, if the window is closed at this time, due to the broken line Tram windows cannot be opened, making it difficult for owners to escape from the vehicle
