[0002] Currently, car roof panoramic sunroofs (skylights) are mainly divided into two types: panoramic skylights with physical sunshades and panoramic skylights without physical sunshades. The physical sunshades can selectively close the sunshades when the sunlight is strong to prevent direct sunlight from the roof from entering the car, thereby isolating ultraviolet rays and blocking the heat of the sun, bringing health and comfort to the car owner. At the same time, when the light outside the car is soft or the light is dark at night, the sunshades can be selectively opened to increase the light inside the car, and at the same time, it can also widen the field of vision and make people in the car feel more comfortable. The main function of the car roof sunshade device is to selectively open and close to increase or decrease the amount of light passing through, and provide people in the car with a better field of vision and comfortable enjoyment while adjusting the brightness inside the car. At the same time, when the weather is hot, the physical sunshade can play a role in heat insulation and sun protection.

[0003] The existing roof sunshade device is mainly divided into two structures. One is a metal frame assembly structure (such as Figure 1 As shown), the sunshade assembly is installed on the metal frame assembly, and the metal frame assembly is fixed to the glass by screws. The guide rails in the frame where the screws are installed are all made of metal, which is heavy and has a high cost.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figures 3 to 11As shown, the utility model provides a roof sunshade device for fixed sunroof glass, including a glass assembly 1, a frame assembly 2 and a sunshade assembly 3. The glass assembly 1 includes a sunroof glass 10 and a mounting bracket 100. A plurality of mounting brackets 100 are provided around the sunroof glass 10. The mounting bracket 100 includes a connecting portion 101. The connecting portion 101 is connected to the lower edge of the sunroof glass 10 by an adhesive 103. The connecting portion 101 is connected to the lower edge of the sunroof glass 10 by an adhesive 103. 01 is formed with a screw component 102 at the other end; the frame assembly 2 or part of the main body is made of plastic, and is fixed under the skylight glass 10 after being screwed to the screw component 102 by screwing the screw component 2 104. The sunshade curtain assembly 3 is arranged at the rear end of the frame assembly 2. When the sunshade curtain needs to be opened or closed, the curtain 30 of the sunshade curtain assembly 3 can slide back and forth along the guide rails 22 on both sides of the frame assembly 2 to be unfolded or wound on the roller 31 of the sunshade curtain assembly 3.

[0032] like Figure 4 、 Figure 5 As shown, the connecting portion 101 is a connecting plate, the first screw member 102 is a stud vertically formed on the plate surface of the connecting plate, and the second screw member 104 is a nut matched with the stud.

[0033] In another embodiment, Figure 10 、 Figure 11 As shown, a bushing 105 is provided between the stud 102 and the mounting hole 221 of the frame assembly 2, and the bushing 105 includes an embedding section 106. The end of the embedding section 106 of the bushing 105 extends radially outward to form a locking pressure edge 107. The front end face of the embedding section 106 of the bushing 105 abuts against the connecting piece 101, and the locking pressure edge 107 is buckled on the edge of the mounting hole 221. The nut 104 is screwed onto the stud 102 and locks the bushing 105. Preferably, the bushing 105 is made of metal.

[0034] In another embodiment, the first screw-connecting member 102 can be fixed to the nut on the connecting plate by welding, and the second screw-connecting member 104 can be fixed to the nut by a screw that matches the nut.

[0035] In another embodiment, the connecting portion 4 is a connecting block, the first screw member 102 is an inner screw hole provided on the connecting block, and the second screw member 104 is a screw matched with the inner screw hole.

[0036] Specifically, if Figure 8 、 Figure 9As shown, the frame assembly 2 includes a front crossbeam 20, a rear crossbeam 21 and two guide rails 22. The front crossbeam 20 and the rear crossbeam 21 are respectively provided with plug-in parts 201 at both ends. The ends of the guide rails 22 are plug-fitted and connected with the plug-in parts 201, and are locked and connected by screws 202 on the outer sides of the guide rails 22, finally forming a frame assembly 2 with a square structure.

[0037] like Figure 7 As shown, the sunshade curtain assembly 3 includes a curtain 30, a sunshade curtain reel 31, a front beam 32, and a winding wheel 33. One end of the curtain 30 is fixed to the reel 31, and the other end of the curtain 30 is connected to the front beam 32. Both ends of the front beam 32 are slidably connected to the guide rail 22 of the frame assembly 2 through sliding feet 35. Anti-slip edge strips 301 are respectively provided on both sides of the curtain 30 and are slidably connected to the guide rail 22 of the frame assembly 2. Both ends of the sunshade curtain reel 31 are synchronously torque-connected with the winding wheel 33, and are rotatable with the rear end of the frame assembly 2 through the winding wheel 33. The winding wheel 33 is dynamically connected with one end of a cable 34, and the other end of the cable 34 is connected to the front beam 32 by passing through the guide wheel 201 arranged at the front end of the front crossbeam 20. The connection point of the cable 34 and the winding wheel 33 and the connection point of the curtain 30 and the sunshade roller 31 are arranged opposite to each other, so that when the sunshade roller 31 rotates, the movement of the curtain 30 and the cable 34 is opposite, that is, when the curtain 30 is rolled up on the sunshade roller, the cable 34 is unrolled from the winding wheel 33; one of the winding wheels 33 is connected to the output shaft torque of the L-shaped motor 4.

[0038] like Figure 6 As shown, the cross-section of the guide rail 22 is arranged from the outside to the inside as a cable sliding groove A, a bolt installation area B, a sliding foot sliding groove C, and an anti-slip edge strip sliding groove D. The utility model sets the bolt installation area of ​​the guide rail 22 in the middle position of the guide rail 22, that is, between the cable sliding groove A and the sliding foot sliding groove C. Compared with the traditional metal frame assembly structure in which the fixed connection point is set at the edge of the frame, its connection is more stable and firm.

[0039] Further improvements are as follows: Figure 7 As shown, the cable 34 passes around the guide wheel and is connected to the end of the spring 36 arranged inside the front beam 32 through the sliding foot 35. The spring 36 can provide pre-tightening force in the front and rear directions of the sunshade and absorb deviations during movement, thereby continuously maintaining the tension of the sunshade curtain and preventing the curtain from sagging in the middle.

[0040] In actual application of the present invention, the guide rail 22 can be selected in different ways according to the conditions of use. Available materials include PVC, PC+ABS, and PA66+GF20, etc., which are selected according to the conditions of use. Among them, PA66+GF20 material has good weather resistance and moderate strength, and can meet the use requirements through structural optimization. PC+ABS material has moderate weather resistance and weak strength, and requires cross-sectional structure reinforcement to meet the use requirements. PVC material has good strength and poor weather resistance, and is suitable for situations with lower temperature requirements.

[0041] It should be understood that the directional words are established in combination with the daily operating habits of operators and users and the drawings in the specification, and their appearance should not affect the scope of protection of the present utility model.

[0042] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. A person skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention. The scope of protection of the present invention shall be determined by the scope defined in the appended claims.
