[0014] Other features and advantages of the present invention will be better understood through the following detailed description of preferred embodiments in conjunction with the accompanying drawings, in which:

[0015] Figure 1 is a schematic diagram of a guide rail of a vehicle sunroof according to a preferred embodiment of the present invention, showing the division of various functional areas;

[0016] Figure 2 and Figure 1 Similarly, the structural features of the guide rail in this embodiment are shown. DETAILED DESCRIPTION

[0017] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of specific ways to implement and use the present invention, and do not limit the scope of the present invention. When describing the structural positions of the various components, such as up, down, top, bottom, etc., the expressions of directions are not absolute, but relative. When the various components are arranged as shown in the figure, these directional expressions are appropriate, but when the positions of the various components in the figure change, these directional expressions also change accordingly. In addition, the "outside" and "inside" used below are directions relative to the vehicle body, "outside" refers to the direction away from the vehicle body, and "inside" refers to the direction facing the vehicle body.

[0018] See first Figure 1 , shows the division of the functional areas of the guide rail of the vehicle sunroof according to a preferred embodiment of the present invention. In this embodiment, the guide rail includes a long strip-shaped body, on which a vehicle body assembly area 10, a sunroof mechanical assembly area 20 and a roller blind assembly area 30 are integrally formed, wherein the sunroof mechanical assembly area 20 is located between the vehicle body assembly area 10 and the roller blind assembly area 30. The guide rail preferably also includes a seal assembly area 40 and a sunroof glass assembly area 50, wherein the seal assembly area 40 includes a first seal assembly area integrally formed above the sunroof mechanical assembly area 20 and a second seal assembly area integrally formed above the roller blind assembly area 30, wherein the sunroof glass assembly area 50 is arranged adjacent to the second seal assembly area. In addition, below the roller blind assembly area 30, the guide rail also includes a roof lining assembly area 60.

[0019] Combination Figure 2 As shown, the vehicle body assembly area 10 includes a flat plate mounting portion 11 extending horizontally from the sunroof mechanical assembly area 20 to the left (away from the vehicle body) to facilitate processing of a mounting structure matching the vehicle body connecting plate. The sunroof mechanical assembly area 20 is provided with a plurality of mounting grooves for assembling sunroof mechanical assembly components, mechanical assembly guide components and windshield strip support components, and is provided with a drainage channel 21, wherein the drainage channel 21 has inclined side walls 22, 23, and preferably has an inclined bottom wall 24, thereby maximizing the use of the limited space of the roof to increase the water storage and drainage volume, and providing the function of guiding and converging the flowing water, thereby improving the drainage management performance.

[0020] The roller blind assembly area 30 is provided for a double roller blind assembly, including two rails 31, 32 arranged in parallel substantially parallel to the longitudinal direction of the guide rail and a curtain running channel 33. The rails 31, 32 can be designed as rails with a substantially circular cross-section, so as to realize the chain operation of the double roller blind system. The connecting surface extending from the rails 31, 32 to the curtain running channel 33 constitutes a support surface 34 of the roller blind slider. In a preferred embodiment, the width of the support surface 34 is greater than or equal to the width of the two rails 31, 32. In this way, the guide rail structure according to the present invention provides a slider support surface with a length that is approximately doubled compared to a conventional guide rail for the operation of the roller blind slider carrier. The structure has a significant optimization effect on preventing the slider carrier from twisting and shaking, and can effectively improve the stability of the roller blind slider carrier, thereby ensuring the running stability of the curtain.

[0021] As described above, the seal assembly area 40 includes two areas. The first seal assembly area is used to seal the gap between the body assembly area 10 and the sunroof mechanical assembly area 20. It is provided with vertical ribs 41 and first hooks 42 for assembling the outer sealing strip and the body sealing strip, so that the general sealing strip and the anti-drop sealing strip can be assembled. The second seal assembly area is used to seal the gap between the sunroof glass assembly area 50 and the roller blind assembly area 30, and is similarly provided with a second hook 43. It is understandable that it is also feasible to provide vertical ribs in the second seal assembly area according to actual needs.

[0022] In the illustrated embodiment, the sunroof glass mounting area 50 includes a planar mounting portion 51 extending substantially vertically upward from the roller blind mounting area 30 , and the complete plane of the planar mounting portion is conducive to machining a corresponding glass mounting structure.

[0023] The roof lining assembly area 60 located below the roller blind assembly area 30 includes two hook-shaped structures 61, 62 extending vertically downward from the roller blind assembly area 30 to accommodate the buckle of the roof lining assembly therebetween. The roof lining assembly area 60 also includes at least one closed cavity. Preferably, a closed cavity 63 is formed below the two tracks 31, 32 of the roller blind assembly area, and one of the two hook-shaped structures 61, 62 constitutes a part of the closed cavity 63. By using the two circular tracks above and a hook-shaped structure 61 to form the closed cavity 63, the guide rail of the present invention helps to strengthen the strength of the guide rail body, and at the same time helps to strengthen the rigidity of the vehicle roof, so that the operation of the sunroof assembly is stable and reliable. The closed cavity is easy to be processed into different external matching structures, has strong plasticity, is easy to process, and is not easy to deform.

[0024] The guide rail of the vehicle sunroof of the present invention is designed with multiple notches on the right side of the guide rail body to integrate the slider of the double rolling sunshade system and other carriers or fabric tensioning structures, the middle of the guide rail body is designed with notches with different functions to integrate the sunroof mechanical group carrier, and the left side of the guide rail body is designed with a plane structure to facilitate the processing of the installation structure matching the vehicle body connecting plate. The overall design structure is novel and the function is reasonable, which has a significant effect on improving the strength and stability of the sunroof assembly, thereby enhancing the reliability of the sunroof assembly. The guide rail body can be made of aluminum alloy parts, which are formed by extrusion process, and the cross section is easier to realize, and the structure can be strengthened, which has high industrial utilization value.
