Glass lifter

Abstract

The invention discloses a glass lifter. The glass lifter comprises a guide rail (1) and sliding blocks (2) arranged inside the guide rail (1), wherein the guide rail (1) is a long groove-shaped guide rail composed of a first guide surface (3) and second guide surfaces (4) arranged on the two sides of the first guide surface (3); the sliding blocks (2) comprise sliding block bodies (8) in corresponding contact with the first guide surface and guide wheels (7) in corresponding contact with the second guide surfaces (4); and the sliding blocks are connected with a lifting mechanism through connecting shafts (5). According to the glass lifter structure, the traditional manner that the sliding blocks are in contact with the guide rail is changed, the motion friction force between the sliding blocks and the guide rail is reduced, the wear speed of the sliding blocks of the lifter is reduced, and the service life of the sliding blocks of the lifter is prolonged.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to body accessories, more specifically, to a glass regulator. Background technique [0002] In the production process of modern automobiles, glass regulators have been widely used in the automobile industry as the main accessories of the body. The glass lifter can be roughly divided into three categories: rope pulley type, wishbone type and flexible shaft type in terms of its structural characteristics. The block slides in the guide rail. Now most of the elevator sliders are square, and they are in surface contact with the guide rail during the lifting movement. Due to the large contact area, the friction between the elevator slider and the guide rail is relatively large, although some designs are in There is lubricating grease between the slider and the guide rail, but as time goes by, the grease is dried or dust is sucked in, and the lubricating effect also disappears.

The glass lifter can be roughly divided into three categories: rope pulley type, wishbone type and flexible shaft type in terms of its structural characteristics. The block slides in the guide rail. Now most of the elevator sliders are square, and they are in surface contact with the guide rail during the lifting movement. Due to the large contact area, the friction between the elevator slider and the guide rail is relatively large, although some designs are in There is lubricating grease between the slider and the guide rail, but as time goes by, the grease is dried or dust is sucked in, and the lubricating effect also disappears. Larger friction will cause serious wear of the slider and affect the service life of the slider
