The lower end of the outer support plate has an arc-shaped cross-section and is supported on the plane of the spring groove. Its structure is simple and stable, and can meet the independent driving operation of two sunshade curtains with dual sliders.

Description

Technical Field

[0001] This utility model relates to the field of sunroof technology, specifically a double slider guide rail structure. Background Technology

[0002] With the development of sunroof technology, the performance requirements for sunshade curtains are increasing. Traditional sunroofs use a single sunshade curtain structure, with a guide groove on the sunroof frame guide to guide the slider of the sunshade curtain. In vehicles with special needs, where two sunshade curtains are required to meet different sunshade requirements, the existing guide rail structure cannot meet the independent unrolling and rolling of the two sunshade curtains. Summary of the Invention

[0003] This utility model provides a simple and stable double slider guide rail structure that can meet the independent driving operation of two sunshade curtains with two sliders.

[0004] The technical solution adopted by this utility model is: a double slider guide rail structure, including a guide rail body, characterized in that: two integrated upper and lower slider grooves are integrally punched on the inner side of the guide rail body, and an inner step and a coil spring groove are arranged sequentially from the inside to the outside on the slider groove. The outer side of the inner step is higher than the plane of the coil spring groove. Two sliders connected to the extension rod of the sunshade curtain are respectively inserted into the upper and lower slider grooves. A coil spring is attached to the lower middle part of the slider via a card. The coil spring is guided and placed in the coil spring groove. An arc-shaped protrusion extending along the direction of the guide rail body is provided below the outer end of the slider and supports it on the plane of the coil spring groove. An outer support plate extending along the direction of the guide rail body and not lower than the height of the inner step side is attached to the slider outside the arc-shaped protrusion. The lower end of the outer support plate has an arc-shaped cross section and the lower end is supported on the plane of the coil spring groove.

[0005] A guide groove is provided inside the inner step, and a slider drive rope or a slider guide head that is attached to the outer end of the slider is built into the guide groove.

[0006] Above the upper slider groove, there is also an upper cover edge integrally stamped from the guide rail body, which corresponds at least above the side of the coil spring groove facing the inner step.

[0007] The bottom of the upper slider groove is a solid stamped structure.

[0008] The bottom of the sliding groove is a stamped structure with only the wall behind it.

[0009] The bottom of the upper sliding groove is not higher than the lower end face of the guide rail body.

[0010] The groove of the coil spring is punched with a downward pressing head structure, which is pressed onto both sides of the coil spring.

[0011] A reinforcing rib extending along the direction of the guide rail body is provided at the corner where the guide rail body is punched to the upper slider and / or the lower slider.

[0012] The beneficial effects of this utility model are as follows: by integrally stamping the upper and lower slider groove structure of the guide rail body and controlling the upper slider groove to be completely higher than the guide rail body, combined with the reinforcing rib structure, the stability of the overall structure is guaranteed; an inner step is set in the slider groove to limit the outer end of the slider, and the outer end of the slider is supported by the outer support plate and the arc-shaped protrusion. The upper ends of the upper and lower sliders are respectively limited by the upper cover edge and the bottom of the upper slider groove, so that the slider is stably supported and constrained in the guide rail, thereby ensuring the smooth, stable and precise guiding movement of the slider driving the sunshade, and realizing the stable unrolling operation of the sunshade driven by the dual sliders independently.

[0015] The following explanation, in conjunction with the accompanying drawings, will provide further details.

[0016] Figure 1 As shown: A double slider guide rail structure includes a guide rail body 1. The inner side of the guide rail body 1 is integrally stamped with upper and lower slider grooves 2 and 5. The bottom 3 of the upper slider groove 2 is not higher than the lower end face of the guide rail body 1.

[0017] An inner step 6 and a spring groove 9 are arranged sequentially from the inside to the outside on the upper and lower slider grooves. The outer side of the inner step 6 is higher than the spring groove plane 8 of the spring groove 9. Two sliders 13, which are connected to the extension rod of the sunshade curtain at their inner ends, are respectively inserted into the upper and lower slider grooves. A spring 11 is attached to the lower middle part of the slider 13 via a clip 12. The spring 11 is guided and placed in the spring groove 9. An arc-shaped protrusion 15 extending along the direction of the guide rail body is provided below the outer end of the slider 13 and is supported on the spring groove plane 8. A slider upper clip 14 extends outward from the upper part of the slider 13. An outer support plate 16 extending along the direction of the guide rail body 1 is attached below the slider upper clip 14. The lower end of the outer support plate 16 has an arc cross section and is supported on the plane of the spring groove 8.

[0018] In this embodiment, an upper cover edge 4 integrally stamped from the guide rail body 1 is also provided above the upper slider groove 2. The upper cover edge 4 corresponds at least above the spring groove plane 8 on the side of the spring groove 9 facing the inner step 6. The height of the upper latch 14 of the slider is not greater than the distance between the upper cover edge and the inner step of the upper slider groove, and not greater than the distance between the bottom of the upper cover edge groove 3 and the inner step of the lower slider groove.

[0019] In this embodiment, the bottom of the upper slider groove is a solid stamped structure. The bottom of the lower slider groove is a stamped structure with only the back wall. This ensures the stable connection strength between the stamped upper and lower slider grooves and the guide rail body.

[0020] In this embodiment, the groove of the coil spring 9 is punched with a downward pressing head 10 structure, which is pressed onto both sides of the coil spring 11.

[0021] Based on this embodiment, a reinforcing rib structure extending along the direction of the guide rail body can also be provided at the corner where the guide rail body is punched and connected to the upper slider and / or the lower slider.

[0022] Based on this embodiment, a guide groove 7 can also be opened at the upper end of the inner step 6. The guide groove 7 has a built-in slider drive rope or a slider guide head attached to the outer end of the slider, which is used to strengthen the guide slider or to connect a reinforcing slider for rope threading.
