Pulling line length automatic adjusting device for window lifter

Abstract

A pulling line length automatic adjusting device for a window lifter comprises a shell with a hollow inside, a pulling line shaft rod and an adjusting member. The pulling line shaft rod and the adjusting member are arranged in the shell, the pulling line shaft rod comprises a shaft seat and a shaft rod extending out from the shaft seat, a first elastic body is abutted between the shaft seat and the inner wall of the shell, the adjusting member is provided with a groove seat and a plurality of positioning blocks movably matched on the groove seat, and a second elastic body is abutted between the shaft seat and the positioning blocks; a plurality of concave-convex positioning portions are arranged on the shaft rod, meshing portions in mutual fit are arranged on the positioning blocks, and the positioning blocks are clamped on the positioning portions of the shaft rod through the meshing portions. Length of a pulling line of the lifter can be adjusted automatically according to wear of parts of the window lifter to enable a window to be constantly maintained relatively stable during adjusting, smooth operation is maintained, and the problems of shaking, forward-backward inclining or operation abnormal sound when conventional lifters are lifted and lowered are solved.

Description

technical field [0001] The invention relates to a vehicle accessory, in particular to a cable length automatic adjustment device for a window lifter.
