Tooth-belt type spring buffering gear lifter

Abstract

A tooth-belt type spring buffering gear lifter comprises a driving mechanism and a lifter support. The tooth-belt type spring buffering gear lifter is characterized in that the upper end and the lower end of the long-strip-shaped lifter support are provided with a transmission belt driven gear and a transmission belt driving gear respectively, connection transmission is carried out through a tooth belt, a sliding block provided with car window glass is fixed on the tooth belt, a sliding groove of the sliding block is clamped to a sliding track of the lifter support, and a transmission belt driving gear shaft is connected with a driving mechanism. The tooth-belt type spring buffering gear lifter has the advantages that the contact area of a lifter transmission belt and a transmission gear is large, force-bearing points are dispersed, the shortcoming that the contact area of a rope wheel type car window lifter steel wire rope and a transmission wheel is small, force-bearing points are concentrated, and abrasion is severe is overcome, the fault occurrence rate of the lifter during a using process is lowered, a driving gear is a buffering gear, the gear is protected, and the service life of the lifter is prolonged.

Description

Technical field [0001] The invention relates to an automobile window lifter, especially a belt drive lifter. Background technique [0002] At present, the transmission of the rope pulley type automotive window regulators on the market is driven by wire ropes. Due to the small contact area between the wire rope and the transmission wheel, the force point is concentrated, the wear of the wire rope and the transmission wheel is relatively large, and it is easy to cause wire breakage during use. Stuck failure; in addition, the drive gear of the lifter does not have a buffer device. When encountering obstacles or suddenly stopping during the window lift process, the drive gear bears a large impact force, which can easily lead to gear damage. The above reasons will lead to vehicle failure. The failure rate of the window regulator increases and the service life is shortened.

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the defects of existing automobile window lifters, the present invention provides a toothed belt type spring buffer gear lifter. Due to the large contact area between the transmission belt and the transmission gear, the force points are scattered, which avoids the problem of the windshield of the rope wheel type automobile window. The contact area between the wire rope of the lifter and the transmission wheel is small, and the force points are concentrated; the drive gear is a buffer gear, which can make the drive gear have a gentle transition process to the impact force when the window is raised or lowered or suddenly stopped. , to protect the gear, prolong the service life of the gear, and reduce the failure rate of the window lifter
