[0043] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0044] In this application, the term "outward" refers to a direction generally pointing to the outside of the vehicle; the term "inward" refers to a direction generally pointing to the inside of the vehicle. The term "lateral" refers to a direction generally the width of the vehicle; the term "longitudinal" refers to a direction generally the length of the vehicle. The term "vertical" refers to a direction generally perpendicular to the sunroof glass.

[0045] Figure 1 A vehicle 1 according to an embodiment of the present application is schematically shown. Figure 1 As shown, the vehicle 1 includes a vehicle body 10, and a sunroof opening 12 is provided on a roof panel 11 of the vehicle body 10. The vehicle 1 also includes a vehicle sunroof system 2. The vehicle sunroof system 2 is installed at the sunroof opening 12. The vehicle sunroof system 2 includes a light-transmitting component (e.g., sunroof glass), and sunlight enters the vehicle compartment through the light-transmitting component.

[0046] According to the following Figures 2 to 8 The vehicle sunroof system 2 will be described.

[0047] like Figure 2 and Figure 3 As shown, the vehicle sunroof system 2 includes a sunroof glass 20, a sunroof frame 30, and a rubber layer 40 formed on the sunroof frame 30. The rubber layer 40 connects the sunroof glass 20 and the sunroof frame 30 together. Figure 5 As shown, a skylight glass opening 301 and a mounting area 303 surrounding the skylight glass opening 301 are configured on the skylight frame 30. A plurality of through holes 302 are configured in the mounting area 303. The through holes 302 are distributed around the skylight glass opening 301 and penetrate the mounting area 303 in the inner and outer directions. Figure 3 and Figure 4As shown, the rubber layer 40 includes a first rubber layer 401 formed on the outer side of the installation area 303, a second rubber layer 402 formed on the inner side of the installation area 303, and a connector 404 formed in the through hole 302. The first rubber layer 401 is connected to the second rubber layer 402 through the connector 404. In addition, the skylight glass 20 is connected to the skylight frame 30 through the first rubber layer 401, so that the skylight glass 20 covers the skylight glass opening 301.

[0048] When manufacturing the vehicle sunroof system 2 of the present application, the sunroof glass 20, the sunroof frame 30 and the mold (not shown in the figure) are first assembled together, and then liquid glue is injected into the mold cavity (for example, the mold cavity at least includes the gap between the sunroof glass 20 and the outer side surface of the installation area 303 and the gap between the inner side surface of the installation area 303 and the mold). After the liquid glue is cured, the first glue layer 401 of the glue coating layer 40 is formed, and the first glue layer 401 is firmly connected to the sunroof glass 20 and the sunroof frame 30 (or the installation area 303), so that the sunroof glass 20 is installed on the sunroof frame 30. The glue coating process is well known to those skilled in the art and will not be described in detail here.

[0049] Since a plurality of through holes 302 are constructed in the installation area 303, during the encapsulation process, when the flow rates of the liquid glue on the outer side surface and the liquid glue on the inner side surface of the installation area 303 are different, the liquid glue with a faster flow rate can flow from one side surface (for example, the outer side surface) of the installation area 303 through the through holes 302 to the other side surface (for example, the inner side surface) of the installation area 303, and merge with the liquid glue with a slower flow rate, so that the flow rates of the liquid glue on the two sides of the installation area 303 remain basically equal, and thus reach the preset flow end point of the liquid glue at basically the same time; and avoid the liquid glue with a faster flow rate from flowing back to the other side surface of the installation area 303 after reaching the flow end point (which will cause the gas on the other side to be stuck between the two liquid glues and unable to be discharged, and eventually bubbles are mixed in the encapsulation layer). Therefore, when manufacturing the vehicle sunroof system 2 of the present application, the gas in the mold cavity is always in front of the liquid glue and is finally discharged at the end of the flow, which avoids the inclusion of bubbles in the rubber layer 40, which helps to improve the quality of the rubber layer 40 and the quality of the vehicle sunroof system 1.

[0050] In addition, during the encapsulation process, the liquid glue will flow into the through hole 302 and eventually form a connector 404 (such as Figure 7As shown in FIG. 1 ). Thus, in the vehicle sunroof system 2 of the present application, the first adhesive layer 401 and the second adhesive layer 402 are also directly connected through the connectors 404. Thus, the first adhesive layer 401 and the second adhesive layer 402 are directly connected at multiple locations, which improves the stability of the first adhesive layer 401 and the second adhesive layer 402 (or the rubber layer 40) on the sunroof frame 30, which also helps to improve the quality of the rubber layer 40 and the quality of the vehicle sunroof system 1.

[0051] In addition, the strength of the sunroof frame 30 is reduced within an allowable range by forming these through holes 302 in the mounting area 303. In this way, when the sunroof glass 20 is matched with the sunroof frame 30, the sunroof frame 30 can be slightly deformed to absorb the manufacturing tolerance, thereby being well matched with the sunroof glass 20.

[0052] In one embodiment, the material of the rubber coating layer 40 is PU (ie, polyurethane). Of course, other materials can also be used to form the rubber coating layer 40 according to actual conditions, which is not limited here.

[0053] Alternatively, if Figure 5 As shown, a first ridge 311 and an extension plate 320 connected to the first ridge 311 are constructed in the installation area 303. The first ridge 311 extends circumferentially around the skylight glass opening 301 and protrudes outward. The extension plate 320 extends from the first ridge 311 toward the skylight glass opening 301. In this case, the through hole 302 is constructed in the extension plate 320. The first glue layer 401 is formed on the outer side of the extension plate 320, and the second glue layer 402 is formed on the inner side of the extension plate 320. In addition, the inner surface of the skylight glass 20 is in contact with the first ridge 311. According to this structure, during the glue encapsulation process, the first ridge 311 and the skylight glass 20 define the flow direction of the liquid glue, preventing the liquid glue from flowing out of the installation area 303, which plays the role of a mold, thereby helping to simplify the mold.

[0054] Optionally, Figure 5As shown, from the overall point of view, the skylight glass opening 301 is generally rectangular, and accordingly, the first rib 311 extends along the circumference of the skylight glass opening 301 to form a rectangle. Specifically, the first rib 311 includes two first extension sections 313 along the longitudinal direction L and two second extension sections 314 along the transverse direction T (that is, the first extension section 313 and the second extension section 314 are generally at a 90-degree angle), and the two second extension sections 314 are respectively connected to the two first extension sections 313. The extension plate 320 correspondingly includes two first plate portions 321 and two second plate portions 322. The two first plate portions 321 correspond to the two first extension sections 313, respectively, and the two second plate portions 322 correspond to the two second extension sections 314, respectively. The first plate portion 321 is smoothly connected to the second plate portion 322. In this way, during the glue coating operation, the liquid glue can flow smoothly along the extension portion 320 to conveniently complete the glue coating operation of the skylight frame 30. Of course, the skylight glass opening 301 may also be in other shapes, and correspondingly, the first ridge 311 and the extension plate 320 may also be in other shapes, which will not be described in detail here.

[0055] Alternatively, if Figure 5 and Figure 6 As shown in FIG. 1 , a second convex rib 312 protruding outward is also configured in the first plate portion 321, and the inner surface of the sunroof glass 20 contacts the second convex rib 312. The second convex rib 312 is parallel to and laterally spaced from the first extension section 313, thereby forming a narrow groove 315 between the second convex rib 312 and the first extension section 313. In this case, a through hole 302 is configured in the narrow groove 315 and a first adhesive layer 401 (such as Figure 7 In addition, a second adhesive layer 402 (as shown) is formed on the inner side of the first plate portion 321 corresponding to the narrow groove 315. Figure 7 As shown in FIG. 3 , the first adhesive layer 401 is connected to the second adhesive layer 402 through the through hole 302. According to the skylight frame 30 of this structure, during the encapsulation process, the liquid adhesive flows in the space surrounded by the skylight glass 20 and the narrow groove 315, so that the skylight glass 20 and the narrow groove 315 act as a mold, which helps to simplify the mold. In addition, after the encapsulation layer 40 is formed on the skylight frame 30, the narrow groove 315 also protects the first adhesive layer 401, preventing the first adhesive layer 401 from being damaged by a large tangential force.

[0056] In one embodiment, a sealing member 317 (such as Figure 7 As shown), to seal the gap between the second convex rib 312 and the skylight glass 20. In other embodiments, similar sealing members may also be provided on the first convex rib 311 and the skylight glass 20, which will not be described in detail here.

[0057] Optionally, Figure 6As described above, the through hole 302 has a long and narrow shape, and the length direction of the through hole 302 is parallel to the length direction of the slot 315. In this way, the long and narrow through hole 302 can be easily constructed in the slot 315. In one embodiment, as Figure 6 As shown, the through hole 302 is substantially rectangular in shape. Of course, the through hole 302 can also be configured in other shapes, such as an ellipse, where the major axis of the ellipse is substantially parallel to the length direction of the slot 315.

[0058] In one embodiment, Figure 7 As shown, the width C1 of the through hole 302 is smaller than the width C2 of the slot 315. For example, the relationship between the width C1 of the through hole 302 and the width C2 of the slot 315 is: C1≤0.8C2; for example, C1≤0.4C2, C1≤0.5C2 or C1≤0.7C2. In addition, the relationship between the length B of the through hole 302 and the width C1 of the through hole 302 can be: 3C1≤B≤12C1; for example, 5C1≤B≤11C1, 6C1≤B≤9C1 or 7C1≤B≤8C1. In this way, during the encapsulation process, part of the liquid glue in the narrow groove 315 can flow through the through hole 302 to the inner side of the first plate body 312, and the remaining liquid glue can still flow forward along the narrow groove 315, thereby reducing the obstruction of the through hole 302 to the flow of liquid glue, which helps to increase the speed of the encapsulation operation; the same is true for the liquid glue on the inner side of the first plate body 312.

[0059] Optionally, Figure 6 As shown, a plurality of through holes 302 are constructed in the slot 315. These through holes 302 are sequentially spaced apart along the length direction of the slot 315. This also helps to reduce the obstruction of the through holes 302 to the flow of the liquid glue. The distance between adjacent through holes 302 can be determined according to actual conditions and is not limited here.

[0060] Optionally, the outer side of the second plate portion 322 is smoothly connected to the narrow groove 315. In this way, during the encapsulation process, the liquid glue can smoothly flow from the narrow groove 315 to the second plate portion 322, or from the second plate portion 322 to the narrow groove 315, thereby conveniently completing the encapsulation operation of the skylight frame 30.

[0061] Alternatively, if Figure 6As shown, a through hole 302 is formed in the second plate portion 322 and / or in the connection area 316 between the second plate portion 322 and the slot 315. For a connection area 316 with a larger area, it is particularly advantageous to form a through hole 302 in the connection area 316, because the provision of the through hole 302 helps to improve the flow of liquid glue on the outer side and the inner side of the connection area 316, not only avoiding the generation of bubbles in the rubber coating layer 40, but also helping to speed up the rubber coating operation. In addition, the first rubber layer 401 formed on the outer side of the connection area 316 and the second rubber layer 402 formed on the inner side are also connected through the through hole 302, thereby improving the stability of the rubber coating layer 40 on the skylight frame 30. The same is true for the through hole 302 formed in the second plate portion 322.

[0062] Alternatively, if Figure 5 and Figure 8 As shown, the edge of the second plate portion 322 adjacent to the skylight glass opening 301 is configured with a flange 323. The flange 323 extends along the vertical V and away from the skylight glass 20. The rubber layer 40 also includes a third rubber layer 403 formed on the flange 323. The third rubber layer 403 is connected to the first rubber layer 401 on the outer side of the second plate portion 322 and the second rubber layer 402 on the inner side of the second plate portion 322. According to this structure, at the second plate portion 322, the first rubber layer 401 and the second rubber layer 402 are also connected to each other, which also improves the stability of the rubber layer 40 on the skylight frame 30. In one embodiment, the first rubber layer 401, the second rubber layer 402 and the third rubber layer 403 are integrally formed; for example, integrally formed by a rubber encapsulation operation.

[0063] Optionally, Figure 5 and Figure 6 As shown, the sunroof frame 30 further includes an accessory mounting portion 318 extending from the second ridge 312 toward the sunroof glass opening 301. There is a gap 319 (eg, Figure 7 For example, the accessory mounting portion 318 is configured in a plate shape and is recessed relative to the second rib 312 to be spaced apart from the sunroof glass 20, so that other accessories can be conveniently mounted on the accessory mounting portion 318. In one embodiment, a sunshade (not shown) can be mounted on the accessory mounting portion 318.

[0064] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
