Description

Technical Field

[0001] The present application relates to the technical field of hemming, and particularly relates to a hemming structure, a sunroof assembly and a vehicle. Background Art

[0002] With the development of vehicle technology, there are more and more product styles of sunroof glass. And due to the tolerances in the production and assembly processes of sunroof glass, there are also more and more cross-section types of existing sunroof glass. However, the existing sunroof glass with multiple cross-section types cannot share a hemming structure for the sunroof glass. Therefore, a forming die for a hemming structure needs to be redesigned correspondingly for each type of sunroof glass, which increases the cost of the hemming structure and the cost of manufacturing the forming die for the hemming structure. Summary of the Utility Model

[0003] The purpose of the present application is to provide a hemming structure, a sunroof assembly and a vehicle. The hemming structure can be adapted to various cross-section types of sunroof glass, without the need to redesign the hemming structure for each type of sunroof glass, saving the cost of the hemming structure and the cost of manufacturing the forming die for the hemming structure.

[0004] An embodiment of the present application provides a hemming structure. The hemming structure includes a base and a soft part. The base includes a base body and a protrusion. The base body includes a first support surface. The protrusion protrudes from the first support surface and is located at the edge of the first support surface. The protrusion includes an inner surface. The inner surface is connected to the first support surface, inclines towards the first support surface, and forms an angle with the first support surface. The soft part includes a soft body and a shielding section. The shielding section is connected to the soft body. The shielding section protrudes from the end of the soft body.

[0007] In one embodiment, the soft part further includes a lapping section. The lapping section protrudes from the side of the soft body facing away from the base and extends away from the base. The lapping section can elastically deform.

[0008] In one embodiment, the soft body includes a first section and a second section. The first section is connected to one end of the second section in the length direction and extends toward the base. The first section is connected to the protrusion, the second section is connected to the protrusion and the base body, and the first section and the second section are connected at an angle. The shielding section protrudes from the end of the first section away from the second section, and the overlapping section is connected to the second section and extends away from the second section.

[0009] In one embodiment, the overlapping section includes an upper surface and a lower surface, and the upper surface and the lower surface face away from each other in the thickness direction of the overlapping section. The overlapping section further includes a recess, and the recess is located at the end of the overlapping section close to the second section, and the recess is recessed in the upper surface or the lower surface.

[0010] In one embodiment, the edge wrapping structure further includes a wear-resistant layer, and the wear-resistant layer covers a part of the lower surface and is spaced from the recess.

[0011] In one embodiment, the material of the base is thermoplastic elastomer or ethylene propylene diene monomer (EPDM). The material of the soft part is thermoplastic elastomer, and the material of the wear-resistant layer is co-extruded lubricant. Or, the material of the soft part is EPDM, and the material of the wear-resistant layer is spray material.

[0012] In one embodiment, the angle is greater than or equal to 70 degrees and less than or equal to 80 degrees.

[0013] In one embodiment, the Shore hardness of the base is greater than the Shore hardness of the soft part.

[0014] In one embodiment, the edge wrapping structure further includes a support member, and the support member is embedded in the base body, and the extending direction of the support member is the same as the extending direction of the base body.

[0015] In one embodiment, the base and the soft part are integrally formed by an extrusion molding process.

[0016] An embodiment of the present application provides a sunroof assembly. The sunroof assembly includes a sunroof glass and the edge structure. The sunroof glass includes a first glass plate and a second glass plate. The first glass plate includes a first side surface and a first surface. The first side surface surrounds and connects to the edge of the first surface. The second glass plate includes a second side surface. The first surface faces away from the second glass plate. The orientations of the first side surface and the second side surface are the same. The edge structure surrounds the edge of the sunroof glass. The inner surface of the sunroof glass and the first support surface are fixedly connected by a connecting member. The inner surface is connected to the first side surface. The shielding section elastically abuts against the connection between the first side surface and the first surface.

The sunroof glass and the edge structure are installed together in the sunroof opening. The sunroof glass covers the sunroof opening. The edge structure is connected between the edge of the sunroof glass and the sheet metal. The base is connected to the second glass plate and the first part. And when the edge structure includes a lapping section, the lapping section elastically abuts against the second part.

[0018] In the related art, the cross-section types of sunroof glass are rich, and the edge structure cannot be applicable to all cross-section types of sunroof glass. Therefore, a separate edge structure needs to be redesigned for each type of sunroof glass, increasing the manufacturing cost of the forming die of the edge structure and the cost of the edge structure. In the embodiment of the present application, the edge structure includes a base and a soft part. The base can support the sunroof glass. The angle between the main body of the base and the protrusion can allow for the assembly tolerance or dimensional deviation existing between the first glass plate and the second glass plate. The protrusion always abuts against the first side surface of the first glass plate, and can shield the gap generated when the sunroof glass is connected to the edge structure due to the uneven side surface. At the same time, the lapping section of the soft part can abut against the sheet metal of the vehicle body, and the shielding section of the soft part can shield the grinding edge defect of the sunroof glass and further shield the gap between the sunroof glass and the base, enabling the edge structure to be suitable for more cross-section types of sunroof glass, saving the cost of the edge structure and the cost of the forming die for making the edge structure, and improving the applicability of the edge structure.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0025] The serial numbers assigned to the components herein, such as "first", "second", and "third", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. The "connection", "installation", and "connection" mentioned in the present application should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0026] Please refer to Figure 1 andFigure 2 , Figure 1 is a schematic structural diagram of a vehicle provided by an embodiment of the present application, Figure 2 and is Figure 1 a schematic cross-sectional view of a partial structure of a sunroof assembly of the vehicle shown in the figure.

[0027] An embodiment of the present application provides a vehicle 1000. According to the use of the vehicle 1000, the vehicle 1000 can be classified into types such as sedans, buses, or trucks. According to the power of the vehicle 1000, the vehicle 1000 can be classified into types such as fuel vehicles, pure electric vehicles, hybrid vehicles, and fuel cell vehicles. In this embodiment, the vehicle 1000 is described by taking a sedan as an example.

[0028] For the convenience of description, in the present application, it is defined that Figure 1 the width direction of the vehicle 1000 shown in the figure is the X-axis direction, the length direction is the Y-axis direction, and the height direction is the Z-axis direction. Among them, the X-axis, Y-axis, and Z-axis are perpendicular to each other in pairs. The orientation terms such as "top", "bottom", "front", and "rear" mentioned in the description of the present application are based on the orientation of the vehicle 1000 shown in the attached drawings of the specification Figure 1 of the vehicle 1000. The "front" of the vehicle 1000 is in the positive direction of the Y-axis, the "rear" of the vehicle 1000 is in the negative direction of the Y-axis, the "top" of the vehicle 1000 is in the positive direction of the Z-axis, and the "bottom" of the vehicle 1000 is in the negative direction of the Z-axis.

[0029] The vehicle 1000 includes a vehicle body 200 and a sunroof assembly 100. The vehicle body 200 includes a sunroof opening 201. Along the Z-axis direction, the sunroof opening 201 is provided at the top of the vehicle body 200. The sunroof opening 201 penetrates through the vehicle body 200 and communicates with the inside and outside of the vehicle 1000. The sunroof opening 201 is used to accommodate the sunroof assembly 100. A sheet metal 202 is provided at the periphery of the sunroof opening 201, that is, the sunroof opening 201 can be understood as an opening surrounded by the sheet metal 202. As Figure 2 shown, the sheet metal 202 includes a first part 203 and a second part 204. The second part 204 surrounds and connects to the first part 203. The first part 203 and the second part 204 form an angle.

[0030] The sunroof assembly 100 includes a sunroof glass 10 and a border structure 20. The border structure 20 is connected between the sunroof glass 10 and the sheet metal 202. The border structure 20 is disposed around the edge of the sunroof glass 10 and is used to carry the sunroof glass 10. The border structure 20 plays roles of sealing, sound insulation, and connection.

[0031] The sunroof glass 10 is installed in the sunroof opening 201 and completely covers the sunroof opening 201. The edge of the sunroof glass 10 is connected to the sheet metal 202 through the edge wrapping structure 20. It can be understood that the positive projection of the sunroof opening 201 in the Z-axis direction is completely within the range of the positive projection of the sunroof glass 10 in the Z-axis direction. The sunroof glass 10 can be used for ventilation of the vehicle 1000 or increasing the lighting inside the vehicle 1000, etc.

[0032] In this embodiment, the sunroof glass 10 can be a panoramic sunroof glass, which further improves the ventilation performance and lighting performance of the vehicle 1000 and brings a good experience to the people inside the vehicle 1000. The sunroof glass 10 can be curved or arc-shaped, or it can also be a flat plate. The shape of the sunroof glass 10 in the embodiments of the present application is not limited, and it can be any shape that meets the usage requirements of the vehicle 1000.

[0033] Please refer to Figure 2 and Figure 3 , Figure 3 which is Figure 2 an exploded cross-sectional schematic diagram of a part of the structure of the sunroof assembly shown.

[0034] In this embodiment, the sunroof glass 10 can be laminated glass. The sunroof glass 10 includes a first glass plate 11, a second glass plate 12, and an intermediate layer 13. Along the thickness direction of the sunroof glass 10 (i.e., the Z-axis direction), the first glass plate 11, the intermediate layer 13, and the second glass plate 12 are laminated and connected in sequence. When the sunroof glass 10 is installed in the sunroof opening 201, the first glass plate 11 faces the outside of the vehicle 1000, and the second glass plate 12 faces the inside of the vehicle 1000. The sunroof glass 10 includes an outer surface, an inner surface, and a side surface. The outer surface and the inner surface are arranged opposite to each other along the thickness direction of the sunroof glass 10. The side surface surrounds the edge of the sunroof glass 10 and is connected between the outer surface and the inner surface.

[0035] Specifically, the first glass plate 11 includes a first surface 111, a second surface 112, and a first side surface 113. The first surface 111 and the second surface 112 are arranged opposite to each other along the thickness direction of the first glass plate 11 (i.e., the Z-axis direction). The first side surface 113 surrounds the edges of the first surface 111 and the second surface 112 and is connected between the first surface 111 and the second surface 112. In this embodiment, the first side surface 113 is an arc surface. The first glass plate 11 can be at least one of high-strength glasses such as silicate glass, high-aluminum glass, or borosilicate glass. When the sunroof glass 10 is installed in the sunroof opening 201, the first surface 111 of the first glass plate 11 faces the outside of the vehicle 1000 and serves as the outer surface of the sunroof glass 10.

[0036] The second glass plate 12 includes a third surface 121, a fourth surface 122, and a second side surface 123. The third surface 121 and the fourth surface 122 are disposed opposite to each other along the thickness direction of the second glass plate 12 (i.e., the Z-axis direction). The second side surface 123 surrounds the edges of the third surface 121 and the fourth surface 122 and is connected between the third surface 121 and the fourth surface 122. In this embodiment, the second side surface 123 is an arc surface. The second glass plate 12 may be at least one of high-strength glasses such as silicate glass, high-aluminum glass, or borosilicate glass. When the skylight glass 10 is installed in the skylight opening 201, the fourth surface 122 of the second glass plate 12 faces the interior of the vehicle 1000 and serves as the inner surface of the skylight glass 10.

[0037] In this embodiment, the orientation of the second side surface 123 of the second glass plate 12 is the same as that of the first side surface 113 of the first glass plate 11. The first side surface 113 and the second side surface 123 together form the side surface of the skylight glass 10.

[0038] It should be noted that in the actual production of the skylight glass 10, there are dimensional tolerances in the production of the first glass plate 11 and the second glass plate 12, and due to process requirements, there is a case where the size of the first glass plate 11 is greater than or equal to the size of the second glass plate 12. At the same time, during the assembly and molding process of the first glass plate 11 and the second glass plate 12, there are assembly tolerances when the first glass plate 11 and the second glass plate 12 are stacked. The dimensional tolerances or the assembly tolerances usually result in an uneven side surface of the skylight glass 10, such that the skylight glass 10 can have multiple cross-sectional types. Specifically, the first side surface 113 usually protrudes relative to the second side surface 123 in the Y-axis direction and the X-axis direction. Alternatively, the first side surface 113 may also be flush with the second side surface 123 in the Y-axis direction and the X-axis direction. In this embodiment, the case where the first side surface 113 is flush with the second side surface 123 in the Y-axis direction and the X-axis direction is taken as an example for description. In other embodiments, the second glass plate 12 may also protrude relative to the first glass plate 11 in the Y-axis direction and the X-axis direction, that is, the second side surface 123 protrudes relative to the first side surface 113 in the Y-axis direction and the X-axis direction.

[0039] The material of the intermediate layer 13 may be, but is not limited to, thermoplastic polymers. Among them, specific examples of thermoplastic polymers may include at least one of Poly Vinyl Butyral (PVB), Ethylene Vinyl Acetate Copolymer (EVA), Poly Urethane (PU), and ionomer (SentryGlas Plus, SGP), etc. The embodiments of the present application do not limit this.

[0040] In this embodiment, the intermediate layer 13 is located between the second surface 112 of the first glass plate 11 and the third surface 121 of the second glass plate 12. The intermediate layer 13 is used to bond the first glass plate 11 and the second glass plate 12 together, improving the structural strength of the sunroof glass 10 and preventing the glass debris from splashing and scratching the occupants inside the vehicle 1000 after the first glass plate 11 or the second glass plate 12 is broken, so that the sunroof glass 10 meets the safety standards and regulatory requirements in more scenarios.

[0041] Please refer to Figure 4 , Figure 4 for Figure 3 a schematic cross-sectional view of a partial structure of the edge structure 20 of the sunroof assembly shown.

[0042] In this embodiment, the edge structure 20 is an annular structure, which is arranged around the edge of the sunroof glass 10 and is connected to the inner surface and the side surface of the sunroof glass 10.

[0043] The edge structure 20 includes a base 30 and a soft part 40. The soft part 40 is connected to the base 30. In this embodiment, the base 30 and the soft part 40 can be integrally formed by an extrusion molding process, solving a series of injection molding defects caused by forming the edge structure 20 by an injection molding method. For example, it is avoided that the material for forming the edge structure 20 solidifies in advance in the part injected first due to the too long flow path during the injection molding process. Or, it is avoided that the material for forming the edge structure 20 is close to the intermediate layer 13 during the injection molding process, resulting in defects such as bubbles or sink marks in the intermediate layer 13.

[0044] The base 30 includes a base body 31 and a protrusion 32. The protrusion 32 protrudes from one side of the base body 31 in the thickness direction and is located at the edge of the base body 31. The base body 31 and the protrusion 32 are connected at an angle. Both the base body 31 and the protrusion 32 are connected to the soft part 40. The protrusion 32 is used to abut against the first side surface 113 of the first glass plate 11, cover the intermediate layer 13 between the first glass plate 11 and the second glass plate 12, and cover the gap between the sunroof glass 10 and the base 30.

[0045] In this embodiment, the base 30 is an annular structure. It can be understood that both the base body 31 and the protrusion 32 are annular structures and surround the edge of the sunroof glass 10. The cross-sectional shape of the base body 31 is generally "T"-shaped. The cross-sectional shape of the protrusion 32 is generally an inverted trapezoid.

[0046] The base body 31 includes a first support surface 311, a second support surface 312 and a connecting surface 313. The first support surface 311 and the second support surface 312 are arranged opposite to each other in the thickness direction of the base body 31. The connecting surface 313 is connected between the first support surface 311 and the second support surface 312. The connecting surface 313 is used to connect to the soft part 40.

[0047] The protrusion 32 protrudes from the first support surface 311 of the base body 31 and is located at the edge of the first support surface 311. The protrusion 32 includes an inner surface 321, an outer surface 322, and a top surface 323. The inner surface 321 and the outer surface 322 are arranged opposite to each other along the thickness direction of the protrusion 32 (i.e., the Y-axis direction). The inner surface 321 is connected to the first support surface 311 of the base body 31, and the inner surface 321 is inclined towards the first support surface 311. An included angle α is formed between the inner surface 321 and the first support surface 311. In this embodiment, the included angle α between the inner surface 321 and the first support surface 311 is greater than or equal to 70 degrees and less than or equal to 80 degrees. In other embodiments, the included angle α between the inner surface 321 and the first support surface 311 can be adaptively adjusted to meet various cross-sectional types of the skylight glass 10.

[0048] The outer surface 322 faces away from the base body 31 and is connected to the connection surface 313 of the base body 31. The orientation of the outer surface 322 of the protrusion 32 is the same as the orientation of the connection surface 313, and the outer surface 322 and the connection surface 313 of the base body 31 form the outer side surface of the base 30. The top surface 323 is connected between the inner surface 321 and the outer surface 322 and is arranged facing away from the base body 31. That is, the orientation of the top surface 323 of the protrusion 32 is the same as the orientation of the first support surface 311 of the base body 31. Both the outer surface 322 and the top surface 323 of the protrusion 32 are used to connect with the soft part 40.

[0049] In this embodiment, the material of the base 30 can be, but is not limited to, thermoplastic elastomer (TPE), ethylene propylene diene monomer (EPDM), etc. The Shore hardness of the base 30 is greater than or equal to 75 SHA and less than or equal to 85 SHA.

[0050] The soft part 40 includes a soft body 41, a lapping section 43, and a shielding section 42. Both the lapping section 43 and the shielding section 42 are connected to the soft body 41 and extend away from the soft body 41. The extending direction of the lapping section 43 is opposite to the extending direction of the shielding section 42. The shielding section 42 extends towards the base 30. The lapping section 43 extends away from the base 30. In this embodiment, the soft part 40 is a ring structure. It can be understood that the soft body 41, the lapping section 43, and the shielding section 42 are all ring structures and are arranged around the edge of the base 30.

[0051] The shape of the soft body 41 matches the shape of the base 30. In this embodiment, the cross-sectional shape of the soft body 41 is generally in the shape of "┐". The soft body 41 includes a first section 44 and a second section 45. The first section 44 is connected to one end of the second section 45 in the length direction (i.e., the Z-axis direction) and extends toward the base 30. The first section 44 and the second section 45 are connected at an angle. The angle between the first section 44 and the second section 45 is adapted to the outer angle formed by the connection of the top surface 323 and the outer surface 322 of the protrusion 32, and the outer angle is the angle between the top surface 323 and the outer surface 322 facing away from the inner surface 321.

[0052] Wherein, the first section 44 includes a first surface 441 and a second surface 442, and the first surface 441 and the second surface 442 are arranged back to back along the thickness direction (i.e., the Z-axis direction) of the first section 44.

[0053] The second section 45 includes a third surface 451 and a fourth surface 452. The third surface 451 and the fourth surface 452 are arranged back to back along the thickness direction (i.e., the Y-axis direction) of the second section 45. The second surface 442 is connected to the third surface 451 and forms an angle. The first surface 441 and the fourth surface 452 are connected.

[0054] In this embodiment, the first section 44 is connected to the protrusion 32. The second surface 442 of the first section 44 is connected to the top surface 323 of the protrusion 32. The first surface 441 faces away from the top surface 323 of the protrusion 32. The second section 45 is connected to the protrusion 32 and the base body 31. The third surface 451 of the second section 45 is connected to the outer side surface of the base 30, that is, the third surface 451 is connected to the connection surface 313 between the outer surface 322 of the protrusion 32 and the base body 31. The fourth surface 452 of the second section 45 faces away from the outer side surface of the base 30.

[0055] Along the Y-axis direction, the shielding section 42 protrudes from the end of the first section 44 away from the second section 45 and protrudes compared with the inner surface 321 of the protrusion 32. The shielding section 42 can be deformed. The shielding section 42 is used to elastically abut against the connection between the first side surface 113 and the first surface 111 of the first glass plate 11. In some embodiments, the shielding section 42 can be directly connected to the connection between the first side surface 113 and the first surface 111 of the first glass plate 11 without deformation.

[0056] The shielding section 42 includes a shielding surface 421 and an abutting surface 422. The shielding surface 421 and the abutting surface 422 are arranged away from each other along the thickness direction of the shielding section 42 (i.e., the Z-axis direction). The shielding surface 421 is connected to the first surface 441 of the first section 44, and the orientation of the shielding surface 421 is the same as that of the first surface 441. The abutting surface 422 is connected to the second surface 442 of the first section 44, and the abutting surface 422 and the first supporting surface 311 of the base body 31 are opposite and spaced apart along the Z-axis direction. The abutting surface 422 is used to abut against the connection between the first side surface 113 and the first surface 111 of the first glass plate 11. The shielding surface 421 is a flat surface and is flush with the first surface 441, which is beneficial to improving the appearance performance of the soft part 40. It should be noted that the length L of the shielding section 42 can be greater than or equal to 1 mm and less than or equal to 2 mm, and specific examples can be 1.25 mm, 1.5 mm, 1.75 mm, etc.

[0057] The overlapping section 43 protrudes from the fourth surface 452 of the second section 45. The overlapping section 43 is used to elastically abut against the vehicle body 200 to seal the vehicle body 200. The overlapping section 43 includes an upper surface 431 and a lower surface 432. The upper surface 431 and the lower surface 432 are arranged away from each other along the thickness direction of the overlapping section 43. Both the upper surface 431 and the lower surface 432 are connected to the fourth surface 452 of the second section 45. In this embodiment, the cross-sectional shape of the overlapping section 43 is arc-shaped. The overlapping section 43 can be deformed and bends towards the first section 44.

[0058] The overlapping section 43 further includes a recess 433. The recess 433 is provided at the end of the overlapping section 43 close to the second section 45. The recess 433 is used to reduce the local thickness of the overlapping section 43, thereby improving the flexibility of the overlapping section 43 and reducing the overlapping force of the overlapping section 43. Preferably, the recess 433 is provided at the connection between the overlapping section 43 and the soft body 41. In this embodiment, the recess 433 is recessed in the lower surface 432 of the overlapping section 43 and is recessed from the lower surface 432 towards the upper surface 431. The opening of the recess 433 is provided in the lower surface 432. In other embodiments, the recess 433 can also be recessed in the upper surface 431 of the overlapping section 43 and is recessed from the upper surface 431 towards the lower surface 432. The opening of the recess 433 is provided in the upper surface 431.

[0059] The software part 40 has the ability of elastic deformation. The material of the software part 40 can be, but is not limited to, thermoplastic elastomer (TPE), ethylene propylene diene monomer (EPDM), etc. The Shore hardness of the software part 40 is greater than or equal to 55 SHA and less than or equal to 65 SHA. In this embodiment, the software body 41, the overlapping section 43 and the shielding section 42 are integrally formed. The software body 41, the overlapping section 43 and the shielding section 42 can be made of the same material and have the same Shore hardness. In some embodiments, the software body 41, the overlapping section 43 and the shielding section 42 can be made of different materials and their Shore hardnesses can also be different from each other.

[0060] The edge wrapping structure 20 further includes a wear-resistant layer 50. The wear-resistant layer 50 is laminated on the overlapping section 43 and is away from the second section 45. The wear-resistant layer 50 covers a part of the lower surface 432 of the overlapping section 43 and is arranged at an interval from the recess 433. The wear-resistant layer 50 is used to connect with the vehicle body 200 and reduce the dynamic friction force between the overlapping section 43 and the vehicle body 200. The material of the wear-resistant layer 50 can be, but is not limited to, co-extruded sliding materials, spraying materials, flocking and other materials with wear-resistant properties. Preferably, the material of the wear-resistant layer 50 is co-extruded sliding materials or spraying materials. When the software part 40 is made of thermoplastic elastomer, the material of the wear-resistant layer 50 is co-extruded sliding materials. When the software part 40 is made of ethylene propylene diene monomer, the material of the wear-resistant layer 50 is spraying materials. The spraying materials can be, but are not limited to, alumina, zirconia, etc.

[0061] The edge wrapping structure 20 further includes a support member 60. The support member 60 is embedded in the base body 31. In this embodiment, the support member 60 is in a strip shape, and its cross-section can be, but is not limited to, circular, L-shaped, linear, etc. The extending direction of the support member 60 is the same as the length extending direction of the base body 31. The material used for the support member 60 can be, but is not limited to, aluminum strips, copper wires, glass fibers, etc. The hardness of the support member 60 is greater than that of the base 30. The support member 60 can play a role in supporting the base 30, thereby improving the structural strength of the edge wrapping structure 20. At the same time, the support member 60 can also be used to reduce the thermal expansion and contraction rate of the base 30 during the molding process, effectively control the influence of temperature on the base 30, and then control the shrinkage amount or stretching amount of the base 30 in the Y-axis direction and the X-axis direction, avoiding the risk of fracture caused by the shrinkage or stretching of the base 30.

[0062] Combined Figure 2 、 Figure 3 and Figure 4, the edge wrapping structure 20 is installed on the edge of the skylight glass 10. The base 30 is connected to the inner surface and the side surface of the skylight glass 10. Specifically, a connecting member 70 is provided between the base body 31 and the skylight glass 10. The connecting member 70 is connected between the first supporting surface 311 of the base body 31 and the edge of the first surface 111 of the first glass plate 11, so that the edge wrapping structure 20 can be fixed on the skylight glass 10. The connecting member 70 can be a double-sided adhesive tape or a colloid. The surface of the connecting member 70 connected to the first supporting surface 311 of the base body 31 has adhesiveness, and the surface of the connecting member 70 connected to the first surface 111 of the first glass plate 11 also has adhesiveness. In some embodiments, the connecting member 70 can also be a fixing block, and the base body 31 is fixedly connected to the skylight glass 10 through the fixing block.

[0063] The inner surface 321 of the protrusion 32 faces the side surface of the skylight glass 10. Since the included angle α between the protrusion 32 and the base body 31 is greater than or equal to 70 degrees and less than or equal to 80 degrees. It can be understood that the inner surface 321 of the protrusion 32 is inclined towards the first side surface 113 of the first glass plate 11 and abuts against the first side surface 113. In this embodiment, since the first side surface 113 of the first glass plate 11 and the second side surface 123 of the second glass plate 12 are flush along the Y-axis direction and the X-axis direction, therefore, the inner surface 321 is closer to the first glass plate 11 than the second glass plate 12. The inner surface 321 of the protrusion 32 abuts against the first side surface 113 of the first glass plate 11 and is opposite and spaced from the second side surface 123 of the second glass plate 12. In some embodiments, when the first side surface 113 protrudes relative to the second side surface 123 along the Y-axis direction and the X-axis direction, the inner surface 321 can also abut against the first side surface 113 and be spaced relative to the second side surface 123. Or, when the second side surface 123 protrudes relative to the first side surface 113 along the Y-axis direction and the X-axis direction, the inner surface 321 can also abut against the first side surface 113. Therefore, in the embodiment of the present application, the specified included angle α between the inner surface 321 and the first supporting surface 311 allows for the assembly tolerance existing when the first glass plate 11 and the second glass plate 12 are stacked, and allows for the dimensional deviation existing when the first glass plate 11 and the second glass plate 12 are produced, avoiding the formation of gaps when the skylight glass 10 and the edge wrapping structure 20 abut due to the uneven side surface of the skylight glass 10, and improving the sealing performance of the edge wrapping structure 20 for the skylight glass 10. Therefore, the edge wrapping structure 20 can be suitable for skylight glasses 10 of more cross-section types, saving the cost of the edge wrapping structure 20 and the cost of the forming mold for manufacturing the edge wrapping structure 20, and improving the applicability of the edge wrapping structure 20.

[0064] The shielding section 42 of the software part 40 elastically abuts against the edge of the first glass plate 11. That is, the abutting surface 422 of the shielding section 42 abuts against the connection between the first side surface 113 and the first surface 111 of the first glass plate 11, and the abutting surface 422 deforms when abutting against the connection between the first side surface 113 and the first surface 111. The shape of the deformed abutting surface 422 matches the shape of the connection between the first side surface 113 and the first surface 111. Exemplarily, the deformed abutting surface 422 is an arc-shaped concave surface, which improves the fitting degree of the shielding section 42 with the skylight glass 10 and ensures the sealing performance of the edge wrapping structure 20 for the skylight glass 10. In some embodiments, the shielding section 42 directly abuts against the first glass plate 11 without deformation, serving to cover the edge of the first glass plate 11. The orthographic projection of the shielding surface 421 of the shielding section 42 in the Z-axis direction at least partially overlaps with the orthographic projection of the first surface 111 of the first glass plate 11 in the Z-axis direction, so that the shielding section 42 covers the edge of the first glass plate 11, and thus the human eye cannot see the edge grinding defects of the skylight glass 10 and the gap between the skylight glass 10 and the base 30 from the outside of the vehicle 1000. This not only improves the appearance performance of the skylight assembly 100, but also increases the cross-section types of the skylight glass 10 that the edge wrapping structure 20 can be applied to.

[0065] The edge wrapping structure 20 and the sunroof glass 10 are installed in the sunroof opening 201 together. The fourth surface 122 of the second glass plate 12 faces the interior of the vehicle body 200 and is opposite to and spaced from the first part 203 of the sheet metal 202. The base body 31 is connected between the second glass plate 12 and the first part 203 of the sheet metal 202. The second support surface 312 of the base body 31 faces the first part 203 of the sheet metal 202, and at least part of the second support surface 312 is connected to the first part 203 to ensure a firm connection between the edge wrapping structure 20, the sunroof glass 10 and the vehicle body 200. The fourth surface 452 of the second section 45 is opposite to and spaced from the second part 204 of the sheet metal 202. One end of the overlapping section 43 away from the second section 45 abuts against the second part 204 and elastically deforms in a direction away from the first part 203. The upper surface 431 of the overlapping section 43 faces away from the sheet metal 202. The lower surface 432 of the overlapping section 43 faces the sheet metal 202. The wear-resistant layer 50 provided on the lower surface 432 is connected to the second part 204 of the sheet metal 202, so that during the driving of the vehicle 1000, the dynamic friction generated when the overlapping section 43 abuts against the second part 204 can be reduced, and the wear between the lower surface 432 of the overlapping section 43 and the second part 204 can be reduced, so as to protect the lower surface 432 of the overlapping section 43 and extend the service life of the overlapping section 43. Since the concave portion 433 is provided on the overlapping section 43, the overlapping force when the overlapping section 43 abuts against the second part 204 is reduced, thereby avoiding the problems of excessive overlapping force and abnormal noise or fracture of the overlapping section 43 when the overlapping section 43 abuts against the second part 204, improving the sealing performance of the edge wrapping structure 20 to the vehicle body 200, and preventing noise or rainwater from entering the interior of the vehicle 1000.

[0066] It should be noted that in this embodiment, since the base 30 and the soft part 40 of the edge wrapping structure 20 are made of materials with different hardnesses respectively. Under the condition of meeting the interference amount between the soft part 40 and the first glass plate 11 and the vehicle body 200 respectively, the Shore hardness of the soft part 40 is less than that of the base 30. The base 30 with a larger hardness is used to support the sunroof glass 10, and the soft part 40 with a smaller hardness is used to abut against the sheet metal 202 of the vehicle body 200, so that the overlapping force when the soft part 40 is connected to the sheet metal 202 is smaller, so that the edge wrapping structure 20 can take into account the connection performance and the sealing performance, and avoid the problem of poor connection between the edge wrapping structure 20 and the vehicle body 200 and the sunroof glass 10 caused by the single material of the edge wrapping structure 20. For example, if the edge wrapping structure 20 has a higher hardness, the overlapping force when the edge wrapping structure 20 abuts against the sheet metal 202 of the vehicle body 200 is larger, and phenomena such as abnormal noise and fracture will occur, reducing the sealing performance of the edge wrapping structure 20 to the vehicle body 200. Or, if the edge wrapping structure 20 has a lower hardness, the edge wrapping structure 20 cannot support the sunroof glass 10, reducing the connection performance between the edge wrapping structure 20 and the sunroof glass 10.

[0067] In the related art, the cross-section types of the sunroof glass 10 are rich, and the edge wrapping structure 20 cannot be applied to all cross-section types of the sunroof glass 10. Therefore, each type of sunroof glass 10 needs to be redesigned with a separate edge wrapping structure 20, which increases the manufacturing cost of the forming die of the edge wrapping structure 20 and the cost of the edge wrapping structure 20. In the embodiments of the present application, the edge wrapping structure 20 includes a base 30 and a soft part 40. The base 30 can support the sunroof glass 10. The included angle α between the base body 31 and the protrusion 32 can allow for the assembly tolerance or dimensional deviation existing between the first glass plate 11 and the second glass plate 12. The protrusion 32 always abuts against the first side surface 113 of the first glass plate 11, and can shield the gap generated when the sunroof glass 10 is connected to the edge wrapping structure 20 due to the uneven side surface. At the same time, the overlapping section 43 of the soft part 40 can abut against the sheet metal 202 of the vehicle body 200, and the shielding section 42 of the soft part 40 can shield the grinding defects of the sunroof glass 10 and further shield the gap between the sunroof glass 10 and the base 30, so that the edge wrapping structure 20 can be suitable for more cross-section types of the sunroof glass 10, saving the cost of the edge wrapping structure 20 and the cost of the forming die for manufacturing the edge wrapping structure 20, and improving the applicability of the edge wrapping structure 20.
