Abstract
Description
Technical Field
[0001] The utility model relates to a sunroof sunshade curtain structure, in particular to a sunshade curtain slider for a car sunroof. Background Art
[0002] With the popularity of sunroofs on cars, the functional requirements of its attached parts are increasing day by day. In particular, the sunshade structure is used to adjust the brightness of the light in the car in real time. It is frequently used. The extension rod of the existing sunshade slides in the sunshade track through the slider to drive the curtain cloth to unwind and realize the sunshade function, but the slider is only positioned by the cable and extension rod on its outer side. During the frequent sliding of the slider back and forth, there is an uncontrollable deviation, which greatly affects the accuracy of unwinding; in addition, in the slider structure of 2023207955304 previously applied by the applicant, the positioning of the slider in the up and down direction is completely limited by the upper and lower ribs in the middle of the slider body. It has high requirements for the component accuracy and assembly accuracy of the slider, ribs and sunshade guide rail. During mass production and assembly, it is impossible to effectively control the precise limit and positioning in the up and down directions, and there is still a problem that the slider shakes up and down to affect the stable unwinding of the extension rod.

[0005] The upper end surface of the extension edge is provided with a plurality of external convex ribs along the sunshade curtain track direction.
[0006] The middle part of the slider body is provided with more than one central convex rib along the direction of the sunshade curtain track on the outer upper end, and the central convex rib is pressed against the upper wall inside the sunshade curtain track.
[0007] The contact section between the lower end of the limiting spring piece and the bottom of the limiting guide groove is a downwardly protruding arc structure.
[0008] The two ends of the limiting spring piece are integrally injection-molded and embedded in the front and rear inner walls of the limiting spring piece through groove along the sunshade curtain track direction.
[0009] The two ends of the limiting spring piece are locked and connected to the bosses or steps on the front and rear inner walls of the limiting spring piece through groove along the sunshade curtain track direction through screws.
[0010] The screw is locked and connected to the limiting spring piece via an elastic gasket.
[0011] The upper end of the screw is sleeved with a guide cap which is pressed against the upper wall in the sunshade track. The guide cap is made of nylon or rubber or the same material as the slider body.
[0012] The beneficial effects of the utility model are:
[0013] 1. On the basis of the original guidance and limitation, a limiting spring piece is added to the slider body, which is clamped and pressed against the limiting spring piece groove on the outside of the sunshade track, so as to realize the guiding limitation of the slider body sliding along the sunshade track; the limiting spring piece presses against the bottom of the limiting spring piece groove, cooperates with the middle convex rib of the slider body, so as to realize the limitation of the slider body in the up and down directions. In the case of component product accuracy error, it can effectively meet the requirements of assembly accuracy and upper and lower limit accuracy.
[0014] 2. The limit spring piece is connected by screw locking, and the guide cap on the upper end of the screw can be self-adjusted or the height can be adjusted with the screw through the elastic gasket, so that the guide cap can be pressed against the upper wall of the sunshade track, adapt to the use of components and assembly precision adjustment, and further improve the upper and lower limit precision of the slider body.
