Supporting and movement mechanism of car sunroof

Abstract

The invention discloses a supporting and movement mechanism of a car sunroof. The supporting and movement mechanism comprises a movement supporting arm, a linkage lift arm and a driving mechanism combined with the linkage lift arm in a clamped mode. The movement supporting arm is provided with at least one locking hole. The lower end of the front end portion of the movement supporting arm is provided with front sliding blocks. The rear portion of the movement supporting arm is provided with a curved groove. The linkage lift arm comprises an inner side plate, an outer side plate and a linkage pin shaft. The lower end of the inner side plate and the lower end of the outer side plate are each provided with a rear sliding block. The driving mechanism is connected with the side face of the lower portion of the inner side plate of the linkage lift arm in a clamped mode. The upper portion of the inner side plate and the upper portion of the outer side plate are fixed together through the linkage pin shaft. A mechanism buffer pad is arranged between the opposite inner sides of the lower portions of the inner side plate and the outer side plate. The linkage pin shaft can slide along the curved groove. Through the design of the through curved groove and the shaft-pin linkage structure, the mechanism linkage stability of the movement supporting arm and the linkage lift arm is effectively improved; meanwhile, the mechanism buffer pad of the linkage lift arm is introduced, so that abnormal sounds and abrasion caused by collisions of the tail ends of mechanism components in the operating state are avoided.

Description

technical field [0001] The invention relates to the technical field of automobile sunroof production, in particular to a supporting movement mechanism of the automobile sunroof. Background technique [0002] The sunroof motion connection mechanism is used to realize the opening and closing of the sunroof or other use states. At present, the tilting mechanism of most automobile sunroofs on the market is mainly composed of slide rails, moving support arms, linkage lifting arms, mechanism limiters, Mechanism slider and other components, the bottom of the moving support arm is in contact with the limit piece in the slide rail, one fulcrum on the linked lifting arm slides in the curved groove on the moving support arm, the other fulcrum is fixed in the slide rail, and the movement The three components of the support arm, the linkage lifting arm and the slide rail form a triangle. The tilting movement of the sunroof is realized through the displacement of the linked lifting arm o...

AI Technical Summary

Problems solved by technology

The tilting movement of the sunroof is realized through the displacement of the linked lifting arm on the slide rail. However, in the prior art, there are many parts in the supporting movement mechanism of the car, which makes the tilting movement of the sunroof unstable. It is easy to be damaged. When the sunroof opens and closes, the contact between the parts will inevitably collide due to the movement, resulting in technical problems such as abnormal noise and component strain in the sunroof mechanism.
