Belt type elastic piece buffering gear lifter

Abstract

A belt type elastic piece buffering gear lifter comprises a driving mechanism and a lifter support. The belt type elastic piece 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 and are in connection transmission through a transmission belt provided with a tooth hole, a partitioning piece is arranged on the lifter support and separates a front side belt and a back side belt of the transmission belt, a sliding block provided with car window glass is fixed on the front side 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 belt type elastic piece buffering gear lifter has the advantages that the contact area of the lifter transmission belt and a transmission gear is large, force bearing points are dispersed, abrasion is low, a buffering gear can protect the gear when a car window meets an obstacle during lifting or is stopped suddenly, 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 automobile 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, and the wear of the wire rope and the transmission wheel is relatively large; in addition, the driving gear of the lifter is not With a buffer device, when the window lifter encounters an obstacle or stops suddenly, the drive gear will bear a large impact force, which will easily lead to gear damage. The above reasons will lead to an increase in the failure rate of the window lifter and a shortened service life. Contents of the invention [0003] In order to overcome the defects of the existing automobile window lifter, the present invention provides a belt-type shrapnel buffer gear lifter. Due to the large...

Problems solved by technology

[0003] In order to overcome the defects of the existing automobile window lifter, the present invention provides a belt-type shrapnel buffer gear lifter. Due to the large contact area between the transmission belt and the transmission gear, the force points are scattered, and the lifting of the window like the rope wheel type is avoided. The contact area between the steel wire rope and the transmission wheel is small, and the stress point is concentrated; the driving 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 or lowered or suddenly stopped. Protects the gears, prolongs the service life of the gears, and reduces the failure rate of the window lifter
