Automobile glass lifting system

Abstract

The invention discloses an automobile glass lifting system. The automobile glass lifting system comprises a glass supporting arm, a motor seat plate, a motor, a gear, a fan-shaped toothed plate, a fan-shaped toothed plate swing arm, a first vertical connecting rod, a first swing connecting rod, a second swing connecting rod, a second vertical connecting rod, a third swing connecting rod, a fourth swing connecting rod, a first hinge seat plate and a second hinge seat plate, wherein the connecting lines of the fan-shaped toothed plate swing arm, the first vertical connecting rod, the first swing connecting rod, a fourth hinge pin and a first hinge pin form a first parallelogram structure; and the second swing connecting rod, the first vertical connecting rod, the second vertical connecting rod and the third swing connecting rod form a second parallelogram structure. Through the connecting rod hinge structures of the double-parallelogram structures, the glass supporting arm is stably and firmly jacked up to lift automobile glass or descends to enable the glass to descend and be opened, and the glass cannot shake or swing in the lifting process; and stable glass lifting can be achieved without the help of a guide rail, and the glass cannot swing or shake in the lifting process when opened or closed.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to an automobile glass lifting system installed in an automobile door for driving the glass to lift. Background technique [0002] At present, there are two commonly used lifting systems for automotive glass: one is as attached figure 1 The rope-wheel type window lifter shown in the figure drives the rope-winding wheel 103 to rotate through the rope-winding wheel motor 100 to pull and move the steel rope 104 arranged in a figure-of-eight shape, and is installed on the guide rail 101 through the movement of the steel rope 104 around the runner 102 The slide block 105 moves, and the automobile glass is installed and fixed on the slide block 105 and is driven by the slide block 105 to move up and down; figure 2 The shown cross-arm glass regulator drives the gear 5 to rotate through the motor 4 installed on the motor seat plate 3, and the gear 5 drives the sector tooth ...

AI Technical Summary

Problems solved by technology

The above two commonly used automotive glass lifting systems both have the function of driving the automotive glass lifting and lowering, and are widely used in practical applications, but both still have deficiencies: figure 1 Due to the setting of the guide rail 101 in the rope-wheel type glass lifter shown, the glass is not easy to shake and swing when the glass is raised and lowered along the guide rail 101, which will cause the glass to close or open, and the glass will be stuck or scratched, but its steel rope 104 It is easy to have winding obstacles due to corrosion and affect the normal lifting of the glass, and it is necessary to add lubricating oil frequently; figure 2 The cross arm type glass regulator shown in the actual use, when the glass is closed or opened, it shakes or swings, so that the glass lifter cannot be lifted more stably when it is opened.
