[0005] In one possible implementation, the slot further includes a transition section connecting the latching section and the push-in section, the transition section gradually decreasing in size along the direction from the push-in section to the latching section.

[0006] In one possible implementation, the area of ​​the mounting opening is larger than the cross-sectional area of ​​other locations of the slot along the length of the slot.

[0007] In one possible implementation, the width of the push-in section gradually increases along the direction from the snap-fit ​​section to the push-in section.

[0008] In one possible implementation, the mounting opening extends along the width of the slot and is inclined along the direction from the push-in section to the snap-fit ​​section.

[0009] In one possible implementation, the snap-fit ​​section includes a closed end located at one end of the snap-fit ​​section away from the push-in section; the bottom wall of the slot is provided with a limiting protrusion located within the push-in section, and the support member is located between the closed end and the limiting protrusion.

[0010] In one possible implementation, the minimum distance between the support member and the limiting protrusion is 0.50mm to 1.5mm.

[0011] In one possible implementation, the length of the snap-fit ​​segment is greater than or equal to half the length of the support member.

[0012] In one possible implementation, the length of the support member is less than the length of the slot, and the difference between the length of the support member and the length of the slot is 3mm to 10mm.

[0013] In one possible implementation, the support member includes a stable snap-fit ​​portion and a variable cross-section portion, the stable snap-fit ​​portion and the variable cross-section portion being fixedly connected along the length direction of the support member, and the cross-sectional area of ​​the variable cross-section portion being smaller than the cross-sectional area of ​​the stable snap-fit ​​portion; when the support member is installed in the slot, the stable snap-fit ​​portion is located within the snap-fit ​​section, and the variable cross-section portion is located within the transition section.

[0014] In one possible implementation, the length of the stabilizing snap-fit ​​portion is greater than the length of the snap-fit ​​segment, and the difference between the length of the stabilizing snap-fit ​​portion and the length of the snap-fit ​​segment is 1mm to 2mm.

[0015] In one possible implementation, the retaining body and the retaining segment are interference-fitted.

[0016] In one possible implementation, the snap-fit ​​section includes a first sub-slot and a second sub-slot, the first sub-slot communicating with the second sub-slot. The retaining body includes a retaining portion and a connecting portion, the connecting portion connecting the retaining portion and the support body. The connecting portion is located within the second sub-slot, and the retaining portion is located within the first sub-slot, and is interference-fitted with the first sub-slot.

[0017] In one possible implementation, the width of the first sub-slot is greater than the width of the second sub-slot, a first limiting step is formed between the first sub-slot and the second sub-slot, and the holding part includes a first limiting end, which is disposed within the first limiting step and is interference-fitted with the first limiting step.

[0018] In one possible implementation, the second sub-slot has a first protrusion on its sidewall, the width of the connecting portion is smaller than the width of the holding portion, a first recess is formed on the outer side of the connecting portion, the first protrusion is located in the first recess and is interference-fitted with the first recess.

[0019] In one possible implementation, the retaining body is provided with a hollow groove, and the hollow groove can deform when the retaining body is engaged in the retaining section.

[0020] In one possible implementation, the sunroof glass assembly further includes a protective member located on the side of the support body opposite to the retaining body and fixedly connected to the support body.

[0021] Secondly, this application also provides a vehicle, including a body and the aforementioned sunroof glass assembly, wherein the sunroof glass assembly is mounted on the body, and the side of the support member facing away from the edging is supported on the vehicle body.

[0022] In summary, the sunroof glass assembly provided in this application achieves a fixed connection between the support and the edging by setting a slot in the edging and a retaining body in the support member. This eliminates the need for grinding or other processes on the edging, simplifying the installation process and saving labor and time costs. Furthermore, by providing a push-in section in the slot, the support member can be installed into the locking section to achieve a locking connection with the slot. That is, the support member can be slid into the slot from the side, thereby reducing the installation force while maintaining the locking strength between the support member and the edging. This avoids the problem of excessive installation force caused by directly locking from the vertical direction, further simplifying the installation process and saving labor and time costs.

[0035] The embodiments of this application are described below with reference to the accompanying drawings.

[0036] This application provides a vehicle (not shown), which includes a sunroof glass assembly and a vehicle body. The sunroof glass assembly is mounted on the roof of the vehicle body and can be opened or closed relative to the vehicle body.

[0037] Please see Figure 1A and Figure 1B , Figure 1A This is a structural schematic diagram of the sunroof glass assembly 100 provided in the embodiments of this application. Figure 1B yes Figure 1A A partial structural diagram of the provided sunroof glass assembly 100.

[0038] The sunroof glass assembly 100 includes a sunroof glass 100A, an edging 10, a support member 20, and a fixing sealant 30. The edging 10 is installed on the side edge of the sunroof glass 100A and is fixedly connected to the sunroof glass 100A. The edging 10 is provided with a groove 40. The support member 20 is partially located within the groove 40 and is held in place by the edging 10. The fixing sealant 30 is installed on the edging 10 and is fixedly connected to the edging 10. In this embodiment, the support member 20 and the groove 40 are located between the sunroof glass 100A and the fixing sealant 30. That is, the support member 20 and the groove 40 are located inside the fixing sealant 30. In other embodiments, the support member 20 and the groove 40 may also be located on the side of the fixing sealant 30 away from the sunroof glass 100A, that is, the support member 20 and the groove 40 are located outside the fixing sealant 30. The sunroof glass assembly 100 is installed on the vehicle body, and the support member 20 is supported on the side of the vehicle body facing away from the edge 10 so that the sunroof glass assembly 100 is installed on the vehicle body. The edge 10 is installed on the vehicle body so as to seal the sunroof glass assembly 100 with the vehicle body.

[0039] For ease of description, in this application, the length direction of the support member 20 is defined as the Y direction, the width direction as the X direction, and the thickness direction as the Z direction. The X, Y, and Z directions are mutually perpendicular. The Z direction is also the height direction of the vehicle.

[0040] In this embodiment, the Z direction is parallel to the normal of the curved surface of the body sheet metal, and the Y direction is consistent with the extension direction of the fixing glass glue 30, so as to save the space occupied by the glass sunroof assembly, reduce the amount of body sheet metal used, and facilitate the installation of the support 20.

[0041] In this embodiment, the sunroof glass 100A is semi-tempered laminated glass. In other embodiments, the sunroof glass 100A can also be tempered glass. In this embodiment, the edging 10 is installed around the perimeter of the sunroof glass 100A and is fixedly and sealed to the sunroof glass 100A. In other embodiments, the edging 10 can also be installed on the side of the sunroof glass or in other positions, as long as the edging 10 is fixedly connected to the sunroof glass 100A. The edging 10 protects the sunroof glass 100A. Simultaneously, when the sunroof glass assembly 100 is installed on the vehicle body, the edging 10 provides a seal, ensuring a sealed and fixed connection between the sunroof glass assembly 100 and the vehicle body, thereby preventing water leakage from the roof.

[0042] In this embodiment, the edging 10 is made of polyurethane (PU). In other embodiments, the edging 10 may also be made of thermoplastic elastomer. The hardness of the edging 10 is Shore A. Specifically, the Shore A hardness of the edging 10 is greater than 60°. In this embodiment, the Shore A hardness of the edging 10 is 60°. In other embodiments, the Shore A hardness of the edging 10 may also be 85° or 80°, etc.

[0043] The edging 10 includes a bottom surface 11, a top surface 12, and a side surface 13. The bottom surface 11 and the top surface 12 are positioned opposite each other and located on opposite sides in the Z direction. The side surface 13 connects the bottom surface 11 and the top surface 12. A slot 40 is provided on the bottom surface 11, and the extending direction of the slot 40 is consistent with the extending direction of the edging 10. One end of the slot 40 extends through the side surface 13, communicating with the outside, to facilitate the installation of the support member 20. When the edging 10 is installed on the sunroof glass, the bottom surface 11 faces the vehicle body, and the support member 20 is supported by the vehicle body. It should be noted that... Figure 1A and Figure 1B Only a portion of the sunroof glass assembly 100 is shown. A support member 20 and its corresponding slot 40 constitute a set of retaining structures. The entire sunroof glass assembly 100 includes multiple sets of retaining structures. That is, multiple sets of slots 40 are provided along the extension direction of the edging 10, and each set of slots 40 corresponds to one support member 20. The number of retaining structures can be adjusted according to actual conditions. Each set of retaining structures can be identical or slightly different in shape or size.

[0044] Please see Figure 2 , Figure 2 yes Figure 1B This is another schematic diagram of a portion of the structure of the sunroof glass assembly 100 shown. Figure 2 The structure of support member 20 is not shown.

[0045] In this embodiment, the slot 40 is flared. The slot 40 includes a bottom wall 401, an end wall 402, a first side wall 403, and a second side wall 404. The first side wall 403 and the second side wall 404 are arranged opposite each other and are located on opposite sides in the X direction, with the first side wall 403 located on the side closer to the sunroof glass. The bottom wall 401 connects the first side wall 403 and the second side wall 404. The end wall 402 connects the first side wall 403 and the second side wall 404, and is located on one side of the slot 40 in the Y direction. The slot 40 also includes a mounting opening 405. The mounting opening 405 is arranged opposite to the end wall 402, and the mounting opening 405 penetrates the side surface 13 and communicates with the outside.

[0046] The slot 40 includes a snap-fit ​​section 41, a transition section 42, and a push-in section 43. The snap-fit ​​section 41, transition section 42, and push-in section 43 are connected sequentially and interconnected, forming the slot 40. The snap-fit ​​section 41 includes a closed end 411 and a first connecting end 412. The first connecting end 412 and the closed end 411 are positioned opposite each other and located at opposite ends along the length of the snap-fit ​​section 41. The snap-fit ​​section 41 has the same width; that is, the width of the closed end 411 is the same as the width of the first connecting end 412. The end wall 402 is located on one side of the closed end 411. The transition section 42 includes a first end 421 and a second end 422. The first end 421 and the second end 422 are positioned opposite each other and located at opposite ends along the length of the transition section 42. The size of the transition section 42 gradually increases from the first end 421 to the second end 422. The first end 421 is fixedly connected to the first connecting end 412. The second end 422 is used to fixably connect to the push-in section 43. The push-in section 43 includes an open end 431 and a second connecting end 432. The open end 431 and the second connecting end 432 are arranged opposite each other and are located at opposite ends of the length direction of the push-in section 43. The second end 422 is fixedly connected to the second connecting end 432. The open end 431 and the closed end 411 are arranged opposite each other along the length direction of the slot 40. The width of the push-in section 43 gradually increases from the second connecting end 432 to the open end 431. The width of the second connecting end 432 is greater than or equal to the width of the second end 422.

[0047] The mounting port 405 is located on one side of the open end 431. The mounting port 405 penetrates the side surface 13 and communicates with the outside. In this embodiment, the mounting port 405 is formed by the ends of the bottom wall 401, the first side wall 403, and the second side wall 404. It can also be understood that the mounting port 405 is provided on one end wall of the slot 40. The end of the bottom wall of the slot forming the mounting port 405 is inclined. Specifically, along the direction from the first side wall 403 to the second side wall 404, the end of the bottom wall of the slot forming the mounting port 405 is inclined from the open end 431 to the closed end 411. That is, the mounting port 405 extends along the width direction of the slot 40 and is inclined along the direction from the push-in section to the snap-fit ​​section 41, thereby making the mounting port 405 in an inclined state. The area of ​​the mounting port 405 is larger than the cross-sectional area of ​​other positions of the slot 40. Understandably, part of the side surface 13 is also an inclined surface, sloping along the first side wall 403 toward the second side wall 404, and part of the side surface 13 is inclined toward the closed end 411. The mounting port 405 penetrates the inclined part of the side surface 13.

[0048] In this embodiment, the total length of the slot 40 is 18mm to 35mm. That is, the dimension of the slot 40 along the Y direction is 18mm to 35mm. In other embodiments, the length of the slot 40 may be greater than 35mm or less than 18mm. The maximum width of the slot 40 is 4mm to 8mm. That is, the maximum dimension of the slot 40 along the X direction is 4mm to 8mm. In other embodiments, the maximum width of the slot 40 may be slightly greater than 8mm or slightly less than 4mm, as long as the support member 20 can be inserted into the slot 40 through the mounting opening 405.

[0049] In this embodiment, by setting the mounting opening 405 to an inclined shape, the size of the mounting opening 405 can be increased without increasing the size of the slot 40, thereby facilitating the installation of the support member 20 and reducing the installation difficulty of the support member 20. Furthermore, when the mounting opening 405 is set to an inclined shape, the side surface 13 near the open end 431 is an inclined surface, which can save material of the edging 10 and reduce the space occupied by the edging 10 in the horizontal direction of the vehicle body.

[0050] Please continue reading. Figure 2 The edging 10 also includes a limiting protrusion 14. In this embodiment, the limiting protrusion 14 is hemispherical. In other embodiments, the limiting protrusion 14 may also be square or other shapes. The limiting protrusion 14 is disposed on the bottom wall 401 of the slot 40 and fixedly connected to the push-in section 43. When the support member 20 is installed on the edging 10, the support member 20 is located between the closed end 411 and the limiting protrusion 14. In this embodiment, the distance from the limiting protrusion 14 to the support member 20 is 0.50mm~1.5mm. In this embodiment, by providing the limiting protrusion 14 in the slot 40, the support member 20 can be limited, thereby preventing the support member 20 from sliding out of the slot 40 due to external force after installation, thus improving the stability of the support member 20 installation.

[0051] Please see Figure 3 , Figure 3 yes Figure 2 A partial cross-sectional structural diagram of the edging 10 in the sunroof glass assembly 100 shown.

[0052] The engaging section 41 of the slot 40 further includes a first sub-slot 44 and a second sub-slot 45. The cross-section of the first sub-slot 44 is approximately trapezoidal. The first sub-slot 44 includes a first bottom surface 441, a second bottom surface 442, a first side surface 443, and a second side surface 444. The first bottom surface 441 and the second bottom surface 442 are parallel and spaced apart, and are located on opposite sides in the Z direction, respectively. The dimension of the first bottom surface 441 in the X direction is smaller than the dimension of the second bottom surface 442 in the X direction. It can be understood that the first bottom surface 441 is the bottom wall 401 of the slot 40 located in the engaging section 41. The first side surface 443 and the second side surface 444 are opposite to each other and are both connected between the first bottom surface 441 and the second bottom surface 442. The cross-section of the second sub-slot 45 is approximately rectangular. The second sub-slot 45 is connected to the second bottom surface 442, and the second sub-slot 45 communicates with the first sub-slot 44. In this embodiment, the dimension of the second sub-slot 45 in the X direction is smaller than the dimension of the second bottom surface 442 in the X direction. In other words, along the direction from the opening of the slot 40 to the bottom wall 401, the size of the slot 40 in the X direction gradually increases and then decreases. Furthermore, the edging 10 forms a first protrusion 451 and a second protrusion 452 on the side wall of the second sub-slot 45, and forms a first limiting step 445 and a second limiting step 446 within the first sub-slot 44. The first limiting step 445 and the second limiting step 446 are used to limit the position of the support member 20, thereby improving the stability of the engagement between the support member 20 and the edging 10.

[0053] Please refer to the following: Figure 4 and Figure 5 , Figure 4 yes Figure 1B The diagram shows the structure of the support member 20 in the sunroof glass assembly 100. Figure 5 yes Figure 4 The cross-sectional structure of the support member 20 shown is along the AA direction.

[0054] In this embodiment, the support member 20 is made of ethylene propylene diene monomer (EPDM) rubber. In other embodiments, the support member 20 may also be made of other rubbers, plastics, or thermoplastic elastomers. The support member 20 has a Shore A hardness. Furthermore, the hardness of the support member 20 is less than the hardness of the edging 10. Specifically, the Shore A hardness of the support member 20 is greater than 60°. In this embodiment, the Shore A hardness of the support member 20 is 60°. In other embodiments, the Shore A hardness of the support member 20 may also be 85°, 80°, or 70°, as long as the hardness of the support member 20 is less than the hardness of the edging 10.

[0055] In this embodiment, by setting the Shore A hardness of both the edging 10 and the support member 20 to be greater than 60°, and setting the hardness of the support member 20 to be less than that of the edging 10, the support member 20 can undergo slight deformation when installed on the edging 10. This makes it easier for the support member 20 to enter the slot 40, achieving a secure connection between the support member 20 and the edging 10. Furthermore, by using a material with lower hardness for the support member 20, it can fit more tightly with the vehicle body when supported on the vehicle body, preventing abnormal noises between the vehicle body and the support member 20.

[0056] The length of the support member 20 is 15mm to 25mm. In this embodiment, the length of the support member 20 is 20mm. That is, the dimension of the support member 20 along the Y direction is 20mm. In other embodiments, the length of the support member 20 may be greater than 20mm or less than 20mm. The height of the support member 20 is 2mm to 6mm. That is, the dimension of the support member 20 along the Z direction is 2mm to 6mm. When the sunroof glass assembly 100 is installed on the vehicle body, the effective support height of the support member 20 is 2mm to 6mm. In this embodiment, the height of the support member 20 is 5.5mm. In other embodiments, the height of the support member 20 may also be 5mm or 2.5mm, etc.

[0057] The support member 20 includes a support body 21 and a retaining body 22. The support body 21 is an elongated block structure. In this embodiment, the support body 21 is a cuboid. In other embodiments, the support body 21 may also be other shapes. The support body 21 includes a first surface 221 and a second surface 222. The first surface 221 and the second surface 222 are disposed opposite to each other and are located on opposite sides of the support body 21 in the thickness direction (Z direction).

[0058] The retaining body 22 includes a retaining portion 23 and a connecting portion 24. The retaining portion 23 has a generally trapezoidal cross-section. The retaining portion 23 includes a third surface 231, a fourth surface 232, a first inclined surface 233, and a second inclined surface 234. The third surface 231 and the fourth surface 232 are arranged opposite to each other and parallel to each other, and the length directions of the third surface 231 and the fourth surface 232 are both parallel to the X-direction. The size of the fourth surface 232 is larger than the size of the third surface 231. The first inclined surface 233 and the second inclined surface 234 are arranged opposite to each other and are both connected between the third surface 231 and the fourth surface 232. The retaining portion 23 also includes a first retaining end 235 and a second retaining end 236. The first retaining end 235 and the second retaining end 236 are arranged opposite to each other, and the first retaining end 235 is located at the connection between the first inclined surface 233 and the fourth surface 232, and the second retaining end 236 is located at the connection between the second inclined surface 234 and the fourth surface 232. In this embodiment, both the first retaining end 235 and the second retaining end 236 are arc-shaped. The first retaining end 235 is used to abut against the first limiting step 445, and the second retaining end 236 is used to abut against the second limiting step 446.

[0059] The cross-section of the connecting portion 24 is approximately rectangular, and the length direction of the connecting portion 24 is parallel to the X-direction. The fourth surface 232 of the retaining portion 23 faces the connecting portion 24 and is fixedly connected to the connecting portion 24. The dimension of the fourth surface 232 along the X-direction is larger than the dimension of the connecting portion 24 along the X-direction. The surface of the connecting portion 24 away from the retaining portion 23 is fixedly connected to the first surface 221. In this embodiment, the support member 20 is a one-piece molded part. In other embodiments, the retaining body 22 and the support body 21 can also be fixedly connected by welding or other means.

[0060] In this embodiment, the dimension of the support body 21 along the X direction is larger than the dimension of the connecting portion 24 along the X direction, and there is a smooth transition between the first surface 221 and the side surface of the connecting portion 24. That is, along the direction from the support body 21 toward the retaining body 22, the dimension of the support member 20 along the X direction decreases, then increases again, and then decreases again. Furthermore, the support member 20 forms a first recess 241 and a second recess 242 on opposite sides of the connecting portion 24. The first recess 241 is correspondingly provided with the first protrusion 451, and the second recess 242 is correspondingly provided with the second protrusion 452.

[0061] In this embodiment, the support member 20 is a long strip with a uniform cross-section. That is, the cross-sectional shape and size of the retaining body 22 are consistent along the XZ plane. It can be understood that by setting the support member 20 as a uniform cross-section structure, the structure of the support member 20 can be simplified, the processing cost can be reduced, and there is no need to consider orientation during installation; simply align the length direction of the support member 20 with the length direction of the slot 40 and push it in.

[0062] In other embodiments, the support member 20 can also be a variable cross-section structure (not shown). That is, the cross-sectional shape and size of the support member 20 along the XZ plane can be different. When the support member 20 is a variable cross-section structure, it includes a stable snap-fit ​​portion and a variable cross-section portion (not shown), which are fixedly connected along the Y direction. The cross-sectional area of ​​the variable cross-section portion is smaller than that of the stable snap-fit ​​portion. When the support member 20 is installed on the edging 10, the stable snap-fit ​​portion is located within the snap-fit ​​section 41, and the variable cross-section portion is located within the transition section 42. The length of the stable snap-fit ​​portion is 1mm to 2mm longer than the length of the snap-fit ​​section 41 to ensure that the support member 20 can be stably snapped into the slot 40. In this embodiment, by setting the support member 20 as a variable cross-section structure, the material usage of the support member 20 can be saved while ensuring stable snapping between the support member 20 and the edging 10, thereby reducing costs. It should be noted that when the support member 20 has a variable cross-section structure, when installing the support member 20 into the slot 40, the stabilizing locking section 41 needs to be pushed in towards the locking section 41 to achieve the installation of the support member 20. In other words, when the support member 20 has a variable cross-section structure, orientation needs to be considered during installation.

[0063] Please refer to the following: Figure 1B and Figure 6 , Figure 6 yes Figure 1B A partial cross-sectional structural diagram of the sunroof glass assembly 100 shown.

[0064] The support member 20 is installed on the edging 10 and engages with it. The support member 20 is located within the slot 40 and between the closed end 411 and the limiting protrusion 14. In this embodiment, part of the retaining body 22 engages with the engaging section 41, and part of the retaining body 22 is located within the transition section 42. In other embodiments, the retaining body 22 may also be completely located within the engaging section 41 and engage with it. The retaining body 22 is located within the slot 40, and the support body 21 is located outside the slot 40, with the first surface 221 abutting against the top surface 12. Of course, the first surface 221 and the top surface 12 may also be in direct contact, or there may be a small gap between the first surface 221 and the top surface 12. The connecting portion 24 of the retaining body 22 is located within the second sub-slot 45, the first protrusion 451 is located within the first recess 241, and the second protrusion 452 is located within the second recess 242. The gap between the first protrusion 451 and the bottom wall of the first recess 241 is 0.05mm to 0.25mm. That is, the gap between the first protrusion 451 and the connecting portion 24 in the X direction is 0.05mm to 0.25mm. In this embodiment, the gap between the first protrusion 451 and the bottom wall of the first recess 241 is 0.1mm. In other embodiments, the gap between the first protrusion 451 and the bottom wall of the first recess 241 can also be 0.25mm. Of course, the first protrusion 451 can also be in direct contact with the bottom wall of the first recess 241. The gap between the second protrusion 452 and the bottom wall of the second recess 242 is 0.05mm to 0.25mm. Of course, the second protrusion 452 can also be in direct contact with the bottom wall of the second recess 242.

[0065] The retaining portion 23 of the retaining body 22 is located within the first sub-slot 44, with the third surface 231 facing the first bottom surface 441 of the first sub-slot 44. The first retaining end 235 abuts against the first limiting step 445, and the second retaining end 236 abuts against the second limiting step 446. The gap between the third surface 231 and the first bottom surface 441 is 0.2mm to 0.8mm. In this embodiment, the gap between the third surface 231 and the first bottom surface 441 is 0.29mm. In other embodiments, the gap between the third surface 231 and the first bottom surface 441 can also be 0.4mm or 0.6mm. Of course, the third surface 231 can also directly contact the first bottom surface 441. The retaining portion 23 is interference-fitted with the first sub-slot 44. The first retaining end 235 abuts against the first limiting step 445, and the interference between the first retaining end 235 and the first limiting step 445 is 0.05mm to 0.25mm. In this embodiment, the interference between the first holding end 235 and the first limiting step 445 is 0.1 mm. In other embodiments, the interference between the first holding end 235 and the first limiting step 445 can also be 0.2 mm, 0.15 mm, or 0.25 mm. The second holding end 236 abuts against the second limiting step 446, and the interference between the second holding end 236 and the second limiting step 446 is 0.05 mm to 0.25 mm. It is understood that the interference fit between the support member 20 and the edge banding 10 is 0.1 mm to 0.50 mm. In this embodiment, by interfering with the holding part 23 and the first sub-groove 44, that is, by interfering with the holding body 22 and the groove 40, the stability of the connection between the support member 20 and the edge banding 10 can be improved.

[0066] During actual installation, firstly, the retaining body 22 of the support member 20 is aligned with the open end 431 of the slot 40. The third surface 231 of the retaining body 22 abuts against the limiting protrusion 14, causing the support member 20 to deform. Then, the support member 20 is pushed towards the locking section 41, causing it to move along the pushing section 43 and the transition section 42 towards the locking section 41 until the support member 20 leaves the limiting protrusion 14 and is located between the closed end 411 and the limiting protrusion 14. At this point, the support member 20 elastically recovers, the retaining body 22 is locked in the locking section 41, and it is press-fitted with the slot 40, thus assembling the support member 20 with the edging 10.

[0067] When the support member 20 is located in the push-in section 43, the retaining body 22 is clearance-fitted with the retaining groove 40, making it easy for the retaining body 22 to be installed into the retaining groove 40 through the push-in section 43. As the width of the transition section 42 gradually decreases from the second end 422 to the first end 421, the force on the retaining body 22 gradually increases as it enters the transition section 42 and is gradually pushed from the second end 422 to the first end 421. After the retaining body 22 is pushed into the snap-fit ​​section 41, it has an interference fit with the snap-fit ​​section 41, and the interference between the edge banding 10 and the retaining body 22 gradually increases, generating an anti-disengagement force, thereby achieving a snap-fit ​​fit between the support member 20 and the edge banding 10. When the support member 20 is fully pushed into place, it is located between the closed end 411 and the limiting protrusion 14. The distance between the support member 20 and the limiting protrusion 14 is 0.5mm to 1.5mm. In this embodiment, by setting the limiting protrusion 14, the support member 20 can be limited, preventing it from sliding and disengaging from the open end 431 into the slot 40, thus improving the stability of the support member 20 installation and the structural stability of the sunroof glass assembly 100. Furthermore, in this embodiment, by setting the distance from the support member 20 to the limiting protrusion 14 to 0.5mm~1.5mm, the assembly of the support member 20 with the edging 10 can be facilitated while meeting the installation position tolerance of the support member 20.

[0068] According to CAE analysis, in this embodiment, the normal pull-out force between the edge banding 10 and the support member 20 is 1.47 N / mm. It should be explained that the "normal pull-out force" here refers to the force along the Z-direction that causes the edge banding 10 to separate from the support member 20. "CAE analysis" refers to using computer-aided solutions to analyze the structural mechanical properties of complex engineering projects and products, as well as to optimize structural performance.

[0069] In this embodiment, the length of the snap-fit ​​segment 41 is greater than or equal to half the length of the support member 20 to ensure the snap-fit ​​strength between the support member 20 and the edge banding 10, while also ensuring the structural stability of the glass skylight assembly. In this embodiment, the length of the support member 20 is 3mm to 10mm shorter than the length of the slot 40 to ensure that the support member 20 can be installed into the slot 40.

[0070] In this embodiment, by providing a slot 40 on the edging 10 and a retaining body 22 on the support 20, the support 20 and the edging 10 can be fixedly connected by installing the retaining body 22 into the slot 40. This eliminates the need for grinding or other processes on the edging 10, simplifying the installation process and saving manpower and time. Furthermore, by providing a push-in section 43 in the slot 40, the support 20 can be installed into the locking section 41 via the push-in section 43, thus achieving locking with the slot 40. In other words, the support 20 can be slidably pushed into the slot 40 from the side, thereby reducing the installation force while maintaining the locking strength between the support 20 and the edging 10. This avoids the problem of excessive installation force caused by directly locking from the vertical direction, further simplifying the installation process and saving manpower and time.

[0071] Meanwhile, in this embodiment, after the support member 20 is assembled with the edge banding 10, it can be visually inspected from the side of the slot 40 to see if the support member 20 is installed in place. This makes it easier for installers to check directly after installation, avoiding incomplete engagement between the support member 20 and the edge banding 10, which could affect the engagement strength and reduce the structural stability of the sunroof glass assembly 100.

[0072] In this embodiment, the support member 20 is supported by the vehicle body, which improves the stability of the sunroof glass assembly 100 installation and avoids the problem of abnormal noise during vehicle operation caused by the edge banding 10 directly supporting the vehicle body. The support member 20 in this embodiment provides support for the sunroof glass, ensuring precise installation at a preset height and position. Furthermore, the sunroof glass assembly 100 provided in this embodiment allows for adjustment of the installation height of the sunroof glass by adjusting the effective support height of the support member 20, thus offering greater versatility. In addition, the support member 20 in the sunroof glass assembly 100 provided in this embodiment is not damaged during installation and disassembly, and can be reused, saving resources and costs.

[0073] Furthermore, in this embodiment, while not affecting the snap-fit ​​strength between the support member 20 and the edge banding 10, the cavity size of the slot 40 is relatively large. When the edge banding 10 is prepared by injection molding, the material of the edge banding 10 can be reduced, and the production time of the injection molding process can be reduced, thereby saving costs and increasing production.

[0074] Please see Figure 1B and Figure 6The sunroof glass assembly 100 also includes a protective element 50. In this embodiment, the protective element 50 is made of non-woven fabric. In other embodiments, the protective element 50 may also be made of felt or other materials. The thickness of the protective element 50 is 0.5mm to 1.0mm. In this embodiment, the thickness of the protective element 50 is 0.5mm. The effective support height of the sunroof glass assembly 100 is 6mm. That is, the effective support height of the sunroof glass assembly 100 is the sum of the dimension of the protective element in the Z direction and the dimension of the support body 21 in the Z direction. The protective element 50 is disposed on the second surface 222 of the support body 21 and is fixedly connected to the second surface 222. Specifically, the protective element 50 can be fixedly connected to the second surface 222 by adhesive bonding.

[0075] When the sunroof glass assembly 100 is installed on the vehicle body, the surface of the protective member 50 facing away from the support member 20 contacts the vehicle body. In this embodiment, by providing the protective member 50, the support member 20 can be prevented from directly contacting the vehicle body and causing wear to the vehicle body. At the same time, it can also increase the friction between the sunroof glass assembly 100 and the vehicle body, thereby improving the stability of the installation of the sunroof glass assembly 100.

[0076] Please see Figure 7 , Figure 7 This is a partial cross-sectional structural diagram of the sunroof glass assembly 100 provided in the second embodiment of this application.

[0077] This embodiment and Figure 6 The difference in the illustrated embodiment is that, in this embodiment, the height of the support 21 is 2.5 mm, and the effective support height of the sunroof glass assembly 100 is 3 mm. The interference between the first holding end 235 and the first limiting step 445 is 0.15 mm, and the interference between the second holding end 236 and the second limiting step 446 is 0.15 mm. The gap between the third surface 231 and the first bottom surface 441 is 0.3 mm to 0.5 mm. The gap between the first protrusion 451 and the bottom wall of the first recess 241 is 0.05 mm to 0.25 mm, and the gap between the second protrusion 452 and the bottom wall of the second recess 242 is 0.05 mm to 0.25 mm. The normal pull-out force of the sunroof glass assembly 100 provided in this embodiment is 1.86 N / mm.

[0078] In this embodiment, by increasing the interference between the first holding end 235 and the first limiting step 445, and the interference between the second holding end 236 and the second limiting step 446, the pull-out force of the sunroof glass assembly 100 can be increased, thereby improving the stability of the connection between the edge banding 10 and the support member 20.

[0079] Please see Figure 8 , Figure 8 This is a partial cross-sectional structural diagram of the sunroof glass assembly 100 provided in the third embodiment of this application.

[0080] This embodiment and Figure 6 The difference in the illustrated embodiment is that, in this embodiment, the height of the support 21 is 5mm, and the effective support height of the sunroof glass assembly 100 is 5.5mm. The interference between the first holding end 235 and the first limiting step 445 is 0.15mm~0.25mm, and the interference between the second holding end 236 and the second limiting step 446 is 0.15mm~0.25mm. The gap between the third surface 231 and the first bottom surface 441 is 0.4mm~0.8mm.

The sidewalls of the hollow groove 25 are spaced apart from the outer surface of the support member 20 in both the X and Z directions. That is, the hollow groove 25 is located in the middle of the retaining body 22 and penetrates the retaining body 22 only in the Y direction. The dimension of the connecting portion 24 in the X direction is 2.5mm~3.0mm, the dimension of the hollow groove 25 in the X direction is 1.5mm~2.0mm, and the dimension of the hollow groove 25 in the Z direction is 1.5mm~2.5mm. The hollow groove 25 is located at the center of the connecting portion 24 in the X direction. The vertical distance from the center of the hollow groove 25 to the first surface 221 is 0.8mm~1.5mm. The normal pull-out force of the sunroof glass assembly 100 provided in this embodiment is 2.69N / mm.

[0082] In this embodiment, by increasing the interference between the first retaining end 235 and the first limiting step 445, and the interference between the second retaining end 236 and the second limiting step 446, the pull-out force of the sunroof glass assembly 100 can be increased, thereby improving the stability of the connection between the edging 10 and the support member 20. Furthermore, by providing a hollow groove 25 in the support member 20, the deformation of the support member 20 under stress can be increased, making it easier for the retaining body 22 to be installed into the groove 40, and reducing the installation difficulty between the edging 10 and the support member 20.

[0083] Please see Figure 9 , Figure 9 This is a partial cross-sectional structural diagram of the sunroof glass assembly 100 provided in the fourth embodiment of this application.

[0084] This embodiment and Figure 8The difference in the illustrated embodiment is that, in this embodiment, the height of the support 21 is 2.5mm, and the effective support height of the sunroof glass assembly 100 is 3mm. The gap between the third surface 231 and the first bottom surface 441 is 0.2mm-0.5mm. The gap between the first protrusion 451 and the bottom wall of the first recess 241 is 0.05mm-0.20mm, and the gap between the second protrusion 452 and the bottom wall of the second recess 242 is 0.05mm-0.20mm. The interference between the first holding end 235 and the first limiting step 445 is 0.05mm-0.15mm, and the interference between the second holding end 236 and the second limiting step 446 is 0.05mm-0.15mm. The first protrusion 451 and the bottom wall of the first recess 241 are partially spaced apart and partially interference-fitted. The second protrusion 452 and the bottom wall of the second recess 242 are partially spaced apart and partially interference-fitted. The maximum gap between the first protrusion 451 and the bottom wall of the first recess 241 is 0.05mm to 0.2mm, and the gap between the second protrusion 452 and the bottom wall of the second recess 242 is 0.05mm to 0.2mm.

[0085] The normal pull-out force of the sunroof glass assembly 100 provided in this embodiment is 2.28 N / mm. In this embodiment, by interfering with the first protrusion 451 and the first recess 241, and by interfering with the second protrusion 452 and the second recess 242, the interference between the support member 20 and the edge banding 10 can be increased, thereby further increasing the installation force and pull-out force of the sunroof glass assembly 100 and improving the stability of the connection between the edge banding 10 and the support member 20.

[0086] Please see Figure 10 , Figure 10 This is a partial structural schematic diagram of the sunroof glass assembly 100 provided in the fifth embodiment of this application.

[0087] This embodiment and Figure 1B The difference in the illustrated embodiment is that, in this embodiment, the slot 40 has a symmetrical structure. The widths of the push-in sections 43 are consistent. That is, the width of the open end 431 is consistent with the width of the second connecting end 432. In this embodiment, by setting the slot 40 to a symmetrical structure, the structure of the edge banding 10 can be simplified, the structure of the injection molding mold for the edge banding 10 can be simplified, and the processing and use of the injection mold can be facilitated.

[0088] In this embodiment, the length of the support member 20 is 20mm. The total length of the slot 40 is 25mm. The limiting protrusion 14 is hemispherical with a radius of 1.0mm.
