Abstract

Provided are a car window roller shutter drive device and a use method thereof. The car window roller shutter drive device comprises a fixed frame component (8) fixed to a car body (88), and a roller shutter assembly (9) which can pivot relative to the fixed frame component (8). The roller shutter assembly (9) comprises a roller shutter rolling shaft (81), drive shaft type gears (91) and a partially-pressed pivoting wheel (94), wherein the roller shutter rolling shaft (81) is used for being fixedly connected with the upper end of a roller shutter (92) and can roll the roller shutter (92); the drive shaft type gears (91) are arranged on the front side and the rear side of the roller shutter rolling shaft (81) symmetrically and coaxially; the partially-pressed pivoting wheel (94) is fixedly connected with the lower end of the roller shutter through a flexible dragging cable; and the partially-pressed pivoting wheel (94) is partially pressed by a pivoting partially-pressing spring so that the roller shutter (92) can be tensioned downwards. Two rack drive assemblies positioned on the front side and the rear side of the roller shutter rolling shaft (81) symmetrically are arranged in the fixed frame component (8).

Description

technical field

[0001] The invention relates to the field of vehicle window roller blinds, in particular to a vehicle window roller blind driving device and a method for using the same. Background technique

[0002] Window roller blinds are used to adjustably shade windows and have been widely used in vehicles.

[0003] It is usually considered to use a rack and pinion transmission mode to perform this adjustment in order to provide effective and reliable adjustment of the precise opening range of the curtain.

[0004] However, due to the limited space of the vehicle and the aesthetics of the cabin, the overall size of the rack and pinion is expected to become smaller. In the prior art, an integrally solidified and connected rack is often used for drive in the rack drive, and when it is close to the end of the vehicle body, the movement space of the rack is likely to interfere with the vehicle body.
