Problems solved by technology

[0003] In order to overcome the defects of the existing automobile window lifter, the present invention provides a double-push toothed belt type shrapnel buffer gear self-adaptive slider lifter, because a wheel body capable of rolling is set on the back of the toothed belt where the toothed belt meshes. , so that the back of the toothed belt is changed from the original sliding friction state to rolling friction, so that the frictional resistance is greatly reduced; the self-adaptive slider enables the lifter slider and the chute to be automatically compensated after being worn out, and the phenomenon of stagnation is not easy to occur; the drive The gear is a buffer gear, which can make the driving gear have a gentle transition process to the impact force when the window is raised and lowered or suddenly stopped, which protects the gear, prolongs the service life of the gear, and reduces the vehicle load. Window regulator failure rate

Embodiment Construction

[0024] Figure 1-Figure 12 In the embodiment, a self-adaptive slide block lifter of a double-push toothed belt type shrapnel buffer gear includes a drive mechanism (25), a lifter bracket (11) and a lifter base (38), and is characterized in that: the lifter bracket ( 11) It is a rectangular strip-shaped pipe body, a slit is longitudinally arranged on the side wall of the pipe body to form a slide rail (16), and a rectangular toothed belt guide groove (47) is formed on the inner wall of the pipe body of the lifter support (11), and the toothed belt The guide groove (47) is provided with a toothed belt (13) that can twitch up and down and has toughness, and the toothed belt drive gear (13) and the lower end of the lifter support (11) are located on the lifter base (38). 14) are meshed with each other, and the back side of the toothed belt at the meshing place is provided with a pressing wheel (40) that compresses and pushes the toothed belt (13). The upper end of the toothed belt...

Abstract

A dual-thrust toothed belt type lifter with a spring-strip buffering gear and a self-adaptive sliding block comprises a drive mechanism, a lifter bracket and a lifter base and is characterized in that the lifter bracket is of a rectangular strip-shaped tube body; a seam is formed longitudinally in the side wall of the tube body to form a sliding rail; a rectangular toothed belt guide groove is formed in the internal wall of the tube body of the lifter bracket; and a flexible toothed belt capable of twitching up and down is arranged in the toothed belt guide groove; the toothed belt is engaged with a toothed belt drive gear, which is arranged on the lifter base, at the lower end of the lifter bracket; and a pinch roller for compacting, extruding and pushing the toothed belt is arranged on the back of the toothed belt at the engaged position. The beneficial effects are as follows: the roller body capable of rolling is arranged on the back of the toothed belt at the engaged position of the toothed belt, so that the abrasion is reduced; when the sliding block suffers from abrasion, a pressure spring props against a pulley block to move forward so as to compensate the abrasion of the sliding block; the drive gear is a buffering gear which plays a role in protecting the gear, so that the service life of the lifter is prolonged.

Description

Technical field [0001] The invention relates to a car window lifter, in particular to a double-push toothed belt lifter. Background technique [0002] At present, in the toothed belt lifters on the market, the toothed belt is pushed by the gear arranged on one side of the toothed belt tooth surface. In addition, the sliding block of the lifter is in direct contact with the sliding rail through the chute on the sliding block. Due to the sliding contact, the frictional resistance is relatively large, and the sliding block is seriously worn. The above reasons will cause the window glass to easily Stuck failure occurs; the drive gear of the lifter does not have a buffer device. When encountering obstacles or suddenly stopping during the lifting of the window, the drive gear bears a large impact force, which can easily lead to gear damage. The above reasons will cause the window to be damaged. The failure rate of the elevator increases and the service life is shortened. Conten...
