Motor-undermounted window lifter system used for automobile windows

Abstract

The invention discloses a motor-undermounted window lifter system used for automobile windows. The motor-undermounted window lifter system comprises a guide rail, a guide wheel and a motor. The guidewheel is mounted at the top of the guide rail. A cover plate is fixedly mounted at the bottom of the guide rail in an inserted manner. The motor is fixed to the cover plate. A winding wheel is mountedon a motor rotating shaft of the motor. A lifting sliding block is mounted on the guide rail in a lifting and sliding manner. A winding wheel trough is arranged at the position, corresponding to thewinding wheel, of the cover plate. An oil storage trough is arranged on the edge of the winding wheel trough. The guide rail is provided with a cover plate connecting portion. The positions, on the two sides of an inserting groove, of the cover plate connecting portion are provided with a guide rail inserting end A and a guide rail inserting end B. A guide rail inserting trough A is formed on thecover plate. The guide rail inserting trough is formed on the cover plate, the inserting groove of the cover plate connecting portion is provided with a guide rail elastic sheet, and the cover plate is provided with a guide rail elastic sheet cooperation block. According to the motor-undermounted window lifter system, the motor is arranged at the lower end of the guide rail, the limitation of thethickness of the motor to the automobile door thickness can be eliminated, the space in an automobile becomes larger, the comfort degree of passengers is improved, and meanwhile the cost of a window lifter is reduced.

Description

technical field [0001] The invention relates to the field of lifting and lowering of automobile glass, in particular to a motor-mounted lower-mounted window shaker system for automobile windows. Background technique [0002] Generally, the window shaker of the car window is installed in the middle of the motor, because the thickness of the motor is relatively large, so the door panel will be made relatively thick. If the motor of the window shaker is set at the bottom position, compared with the motor at the middle position, the distance between the motor and the guide wheel is farther. When the motor drives the wire rope to move, it is easy to cause the wire rope to shake from side to side. The motor of the traditional window shaker is directly fixed to the middle of the guide rail by screws. If the motor of the window shaker is placed down, if the motor is fixed to the bottom of the guide rail by screws, since the motor is far away from the guide wheel, the drive provided ...

AI Technical Summary

Problems solved by technology

If the motor of the window shaker is set at the bottom position, compared with the motor at the middle position, the distance between the motor and the guide wheel is farther. When the motor drives the wire rope to move, it is easy to cause the wire rope to shake from side to side

The motor of the traditional window shaker is directly fixed to the middle of the guide rail by screws. If the motor of the window shaker is placed down, if the motor is fixed to the bottom of the guide rail by screws, since the motor is far away from the guide wheel, the drive provided by the motor is easy to provide for the guide rail. Larger torque at the bottom will easily cause the motor cover and the bottom of the guide rail to loosen

Therefore, in order to realize the under-mounted motor, it is necessary to solve the stability problem of the motor, the cover plate, and the bottom of the guide rail under the operation of the motor, and the shaking of the wire rope is likely to cause the vibration of the lifting slider, which affects the user experience and the service life of the product. will reduce
