Circulating linkage mechanism of automobile sunshade curtain

Abstract

The invention discloses a circulating linkage mechanism of an automobile sunshade curtain. The mechanism comprises a window frame, a sunshade curtain frame and a differential part. The sunshade curtain frame comprises sunshade curtain cloth, curtain frame end covers arranged at a left end and a right end of the sunshade curtain frame, and a roller shutter pipe movably arranged in the sunshade curtain frame. Inner fixing pieces are fixedly arranged on inner sides of the left end and the right end of the roller shutter pipe respectively, outer fixing pieces are fixedly arranged on outer sides ofthe left end and the right end of the roller shutter pipe respectively, and differential mechanisms are movably arranged in shaft holes between the inner fixing pieces and the outer fixing pieces. The differential part comprises a main shaft, a spring sleeve shaft, a grooved pulley fixing shaft and a movable rotating shaft, a first spring groove is formed in the inner end of the differential part, a second spring groove is formed in the outer fixing pieces, and a torsion spring is arranged on a spring sleeve shaft between the first spring groove and the second spring groove; and a traction sheave is arranged in a sheave fixing shaft. The mechanism is simpler and more reasonable in structure, easy and convenient to manufacture and install, free of any external force and capable of truly achieving random staying.

Description

technical field [0001] The invention relates to a sunshade curtain, in particular to the field of auto parts. The sunshade curtain is scientific and reasonable in structure, simple in manufacture, convenient in installation, safe in use and practical, and is used for sunroofs, rear windows or side windows of vehicles. Cycle linkage mechanism. Background technique [0002] The sunshade that can prevent dust and sunshade is widely used in existing vehicles. It is composed of a curtain frame, a curtain fabric, a roller shutter tube and a torsion energy storage spring. A torsion energy storage spring is arranged between the roller shade tube and the curtain frame. , the inner end of the curtain is fixedly connected to the roller shade tube, and the outer side of the curtain is fixedly connected to the limit bar. The torsion energy storage spring always winds the curtain on the roller roller tube, that is, the curtain is always in the state of automatic retraction. , it needs to...

AI Technical Summary

Problems solved by technology

Also because the thickness of the curtain is about 0.6 mm, and to form a relative angle and a relatively restrictive rubber strip, its thickness should be at least not less than 1 mm, so that the two are overlapped together, and its thickness is above 1.6 mm. When the curtain tube (inner tube) rolls up the curtain, there is a large difference between the two sides of the curtain and the middle, and there will be uncertain factors when the curtain tube is rolled up, so this design has serious flaws

[0008] And there is no friction or restrictive design between the side bars and the chute, so when the vehicle bumps, they will collide with each other and make abnormal noises

[0009] Based on the above problems, its technical solution is difficult to implement
