Method and device for lifting door/window glass of car

Abstract

The invention provides a method and a device for lifting door / window glass of a car. A motor drives a lead screw of a screw pair to rotate, rotary motion is changed into linear motion to generate a relatively great transmission ratio, a relatively great axial thrust is obtained by the virtue of a relatively small torque so as to drive glass on a lifting drive arm or a glass dragging plate to move up and down to realize lifting. The method is high in transmission precision and strong in self-locking performance. The device for realizing the method has two modes, i.e., a horizontal transmission mode and a vertical transmission mode, and comprises a motor, the screw pair and a bearing; one end of the lead screw of the screw pair is connected to the output shaft of the motor while the other end thereof is supported through the bearing; a nut support of the screw pair is connected to the lifting drive arm or the glass dragging plate; the lifting drive arm is connected to a sliding guide rail; glass is mounted on the sliding guide rail or the glass dragging plate. The device is simple in structure, flexible to operate, low in cost, long in service life, and suitable for glass doors / windows with different camber lines.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a method for lifting and lowering an automobile door and window glass and a lifting device. Background technique [0002] With the continuous progress and development of the automobile industry, people have higher and higher requirements for automobile performance. The door and window glass of the car not only needs to ensure that the driver has enough viewing angles to achieve the purpose of driving safely; at the same time, in order to meet the needs of riding comfort, the position of the glass often needs to be adjusted, so the adjustment range and maneuverability of the glass become a measure of car performance. an important indicator. [0003] The mechanism used to adjust the glass of the car is the glass regulator, which is also an important part that affects the safety and comfort of the car. The glass regulator refers to a device that raises or lowers the car window glass alon...

Problems solved by technology

[0004] The transmission mechanism of the arm type glass lifter is a gear-tooth plate meshing transmission. Except for the gear, its main components are plate-type structures. Because it adopts a cantilever support structure and a gear-tooth plate mechanism, the working resistance is relatively large

And because the relative position between the supporting point of the lifting arm and the center of mass of the glass changes frequently, the glass will be tilted and stuck when it is raised and lowered, resulting in rapid wear of the parts and poor durability

[0005] The transmission mechanism of the flexible glass lifter is a combination of gears, wire reels, and ropes (or flexible shafts). Short, easy to cause failure of lifting function
