Abstract

The invention provides car window roller shutter drive equipment for preventing stroke excess and a use method thereof. The equipment comprises a fixed frame part (8) fixed to a car body (88), and a roller shutter assembly (9) which can pivot relative to the fixed frame part (8). The roller shutter assembly (9) comprises a roller shutter reel (81) which is fixedly connected with the upper end of a roller shutter (92) and can wind the roller shutter (92), drive shaft type gears (91) symmetrically and coaxially arranged on the front side and the rear side of the roller shutter reel (81), and a bias pivot wheel (94) fixedly connected with the lower end of the roller shutter through a flexible traction mooring rope. The bias pivot wheel (94) is biased by a pivot bias spring so that the roller shutter (92) can be tensioned downwards. Two rack drive assemblies symmetrically positioned on the front side and the rear side of the roller shutter reel (81) are arranged in the fixed frame part (8).

Description

technical field [0001] The invention relates to the field of car window roller blinds, in particular to a car window roller blind driving device for preventing overtravel and a use method thereof. 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. Contents of the invention [0005] The object of the present ...
