[0002] The present invention also relates to the field of vehicle technology, and in particular, to a door glass assembly and a vehicle. Background Technology

[0003] In existing technologies, movable glass requires sliding engagement with another guide rail to guide its movement in a certain direction. Currently, the guide rail is mainly bonded to the movable glass using adhesive (such as two-component PU adhesive). On the one hand, due to the small bonding area, the adhesive performance deteriorates after high-temperature durability tests, making it easy for the guide rail to detach from the movable glass. On the other hand, to control the accuracy of the guide rail bonding position, installation fixtures are required for the assembly of the guide rail. However, due to limitations in the reference positioning method and assembly tolerances, the accuracy of the guide rail bonding position is low, which in turn reduces the accuracy of the sliding engagement between the guide rail and the other guide rail. Furthermore, the assembly process involves many steps and is cumbersome. Summary of the Invention

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Implementation Method 1

[0048] like Figure 1 and Figure 2 As shown, the present invention provides a guide rail glass structure, including: a movable glass 1 having a moving direction; a movable guide rail 2 having a first connecting part 21 and a sliding part 23, the first connecting part 21 being disposed on the inner side surface 11 of the movable glass 1, and the sliding part 23 being connected to the first connecting part 21 and extending along the moving direction; wherein, the movable guide rail 2 is an integrally injection molded plastic part, and the first connecting part 21 and the movable glass 1 are stacked to form a sandwich structure.

[0049] The guide rail glass structure of the present invention forms a sandwich structure by stacking the first connecting part 21 of the movable guide rail 2 with the movable glass 1. This ensures both the stability of the connection between the movable guide rail 2 and the movable glass 1 and the positional accuracy of the movable guide rail 2. It also allows the sliding part 23 of the movable guide rail 2 to slide and cooperate better with the other guide rail along the moving direction. Furthermore, the first connecting part 21 can be used to directly support the movable glass 1, ensuring the structural strength of the movable glass. In addition, the manufacturing process is simple and the operation is straightforward.

[0050] like Figure 1 and Figure 2As shown, specifically, the movable glass 1 can be a single piece of glass with two opposing sides in the thickness direction and multiple edge faces 13 connecting the two sides in the circumferential direction. The multiple edge faces 13 enclose and form the circumferential contour of the movable glass 1. The movable glass 1 can be flat glass or curved glass. The first connecting part 21 of the movable guide rail 2 can be a single piece of plastic sheet structure, and the first connecting part 21 is combined with one side of the movable glass 1. In this embodiment, for ease of description, the side of the movable glass 1 that is combined with the first connecting part 21 is defined as the inner side 11, and the other side is defined as its outer side 12. The sliding part 23 is generally a strip-shaped structure extending along the moving direction, and is integrally injection molded with the first connecting part 21. The specific shape and size of the sliding guide rail can be set according to the sliding fit requirements between it and the other guide rail.

[0051] The specific shape and size of the first joint 21 can be set according to the requirements of the bonding force between it and the movable glass 1, and are not limited by the sliding part 23. When the bonding force between the first joint 21 and the movable glass 1 is greater, the size of the first joint 21 is larger, and the bonding area between the first joint 21 and the movable glass 1 is larger. The smaller the size of the first joint 21, the smaller the bonding area between the first joint 21 and the movable glass 1.

[0052] like Figure 1 and Figure 2 As shown, in the embodiments of the present invention, the movable guide rail 2 is preferably a transparent plastic part, which will not affect the aesthetics of the movable glass 1, and the movable glass 1 will not obstruct it due to its connection with the first joint 21. Furthermore, the material of the movable guide rail 2 is more preferably transparent PC plastic (polycarbonate), which has good transparency, impact resistance, heat resistance, insulation, weather resistance and mechanical strength.

[0053] Therefore, provided the bonding force meets the requirements and the first joint 21 does not obstruct the movable glass 1, the first joint 21 can be configured in any shape and size. In one embodiment of the present invention, the first joint 21 is generally a panel structure with a shape similar to and an area equal to that of the movable glass 1, allowing the first joint 21 to cover the entire inner surface 11 of the movable glass 1, i.e., covering the entire area of ​​the inner surface 11. This maximizes the bonding force between the first joint 21 and the movable glass 1, and allows for better control of the positional accuracy of the first joint 21, whether through high-pressure lamination or integral injection molding. Furthermore, it makes the structure of the movable glass 1 more stable and the stress more uniform.

[0054] In other embodiments of the present invention, the first connecting portion 21 may be a strip-shaped structure extending along one edge of the movable glass 1, or an L-shaped structure extending along adjacent two edge portions of the movable glass 1, or a “П” shape extending along three adjacent edge portions of the movable glass 1, or a frame-shaped structure extending along the circumferential contour of the movable glass 1. Optionally, if the first connecting portion 21 only connects to the edge region of the movable glass 1, the movable guide rail 2 may also be an opaque plastic part.

[0055] like Figure 3 As shown, in an embodiment of the present invention, the movable guide rail 2 further includes a second connecting portion 22, which is connected to the first connecting portion 21. The second connecting portion 22 of the movable guide rail 2 is combined with the edge end face 13 of the movable glass 1 by integral injection molding and / or high-pressure lamination. By providing the second connecting portion 22, on the one hand, the bonding area between the movable guide rail 2 and the movable glass 1 is increased, thereby improving the bonding force and making the structure of the movable guide rail 2 more stable; on the other hand, the second connecting portion 22 can protect the edge end face 13 of the movable glass 1 and compensate for the defect that the edge end face 13 of the movable glass 1 is not subjected to force.

[0056] Specifically, the shape and size of the second joint 22 can be set according to the requirements of the bonding force between it and the movable glass 1, without being limited by the sliding part 23 and the first joint 21. In the embodiment of the present invention, the second joint 22 is a frame structure and can be combined with all the edge end faces 13 of the movable glass 1 along the circumference of the movable glass 1. That is, the circumferential contour of the second joint 22 is roughly the same as that of the movable glass 1 and surrounds the movable glass 1, thereby maximizing the bonding force between the first joint 21 and the movable glass 1, and realizing the protection of each edge end face 13 of the movable glass 1.

[0057] like Figure 1 , Figure 2 as well as Figure 3 As shown, in some embodiments of the present invention, the movable guide rail 2 is integrally injection molded using the same injection molding material, which is simple to operate and has high control precision.

[0058] like Figure 1 and Figure 2 As shown, in some other embodiments of the present invention, the first connecting part 21 and the sliding part 23 of the movable guide rail 2 can be injection molded and integrated using different injection molding materials. For example, the first connecting part 21 can be injection molded using one injection molding material (such as transparent plastic) and the sliding part 23 can be injection molded to the first connecting part 21, and then the sliding part 23 can be injection molded using another injection molding material (such as non-transparent plastic).

[0059] like Figure 3As shown, in some embodiments of the present invention, the first connecting portion 21, the sliding portion 23, and the second connecting portion 22 of the movable guide rail 2 can be injection molded from different injection molding materials and integrated together. For example, the first connecting portion 21 and the sliding portion 23 can be injection molded first using one injection molding material (such as transparent plastic), and then the second connecting portion 22 can be injection molded using another injection molding material (such as non-transparent plastic) and injection molded together with the first connecting portion 21; or the first connecting portion 21 and the second connecting portion 22 can be injection molded first using one injection molding material (such as transparent plastic), and then the sliding portion 23 can be injection molded using another injection molding material (such as non-transparent plastic) and injection molded together with the first connecting portion 21.

[0060] like Figure 3 As shown, in some embodiments of the present invention, the first connecting part 21 and the second connecting part 22 of the movable guide rail 2 are both integrated with the movable glass 1 by integral injection molding.

[0061] like Figure 4 As shown, in some other embodiments of the present invention, the first connecting part 21 of the movable guide rail 2 is combined with the inner side surface 11 of the movable glass 1 by high pressure bonding, and the second connecting part 22 of the movable guide rail 2 is combined with the edge end face 13 of the movable glass 1 by integral injection molding.

[0062] like Figure 5 As shown, in some embodiments of the present invention, the first joint 21 and the second joint 22 of the movable guide rail 2 are both combined with the movable glass 1 by high-pressure bonding.

[0063] In some other embodiments of the present invention, the first connecting part 21 of the movable guide rail 2 is integrated with the inner side surface 11 of the movable glass 1 by integral injection molding, and the second connecting part 22 of the movable guide rail 2 is integrated with the edge end face 13 of the movable glass 1 by high pressure bonding.

[0064] like Figure 1 and Figure 3 As shown, in an embodiment of the present invention, the movable glass 1, in conjunction with the molding die of the movable guide rail 2, forms the molding cavity of the movable guide rail 2. Then, by injecting injection molding material into this molding cavity, the movable guide rail 2 is integrally injection molded. The first connecting part 21 of the movable guide rail 2 is injection molded on one side of the movable glass 1, thus forming a sandwich structure with the movable glass 1. For example... Figure 1 As shown, in some embodiments of the present invention, only the inner surface 11 of the movable glass 1 and the surface of the molding die form the molding cavity of the movable guide rail 2, so that the injection molding material is solidified on the inner surface 11 of the movable glass 1 to form the first joint 21. Figure 3As shown, in some other embodiments of the present invention, the inner side surface 11 of the movable glass 1 and the edge end face 13 of the movable glass 1 are enclosed with the surface of the molding mold to form the molding cavity of the movable guide rail 2, so that the injection molding material is cured on the inner side surface 11 of the movable glass 1 to form a first joint 21, and on the edge end face 13 of the movable glass 1 to form a second joint 22.

[0065] Specifically, in order to improve the injection molding bonding force between the first joint 21 and the inner side surface 11 of the movable glass 1, a base coating 8 can be applied to the inner side surface 11 of the movable glass 1 before injection molding. Similarly, a base coating 8 can also be applied to the edge end face 13 of the movable glass 1.

[0066] like Figure 2 and Figure 4 As shown, in some embodiments of the present invention, the high-pressure bonding between the first joint 21 and the movable glass 1 is achieved by providing a first intermediate layer 6. The first intermediate layer 6 is stacked between the inner surface 11 of the movable glass 1 and the first joint 21. After being hot-pressed, the first intermediate layer 6 becomes adhesive and is integrally bonded with the first joint 21 and the inner surface 11 of the movable glass 1. Figure 5 As shown, the high-pressure bonding between the second joint 22 and the movable glass 1 is achieved by providing a second intermediate layer 7. The second intermediate layer 7 is stacked between the edge end face 13 of the movable glass 1 and the second joint 22. After being hot-pressed, the second intermediate layer 7 becomes adhesive and is integrated with the second joint 22 and the edge end face 13 of the movable glass 1 by high-pressure bonding.

[0067] Specifically, the first intermediate layer 6 is preferably a PVB film or EVA film with good light transmittance, so that the first intermediate layer 6 will not obstruct the movable glass 1. The second intermediate layer 7 can also be a PVB film or EVA film with good light transmittance, preferably an EVA film with better fluidity after hot pressing, making the entire guide rail glass structure more aesthetically pleasing. Optionally, since the second intermediate layer 7 is located between the second joint 22 and the edge end face 13 of the movable glass 1, the second intermediate layer 7 can also be an opaque film. Optionally, if the first joint 21 is only joined to the edge area of ​​the movable glass 1, the first intermediate layer 6 can also be an opaque film. Optionally, the first joint 21 and the movable glass 1 are bonded together by applying adhesive to the movable glass 1 and / or the first joint 21, and the adhesive in the middle cures to form the first intermediate layer 6. Optionally, the second joint 22 and the movable glass 1 are bonded together by applying adhesive to the movable glass 1 and / or the second joint 22, and the adhesive in the middle cures to form the second intermediate layer 7.

[0068] In other embodiments of the present invention, the first intermediate layer 6 and the second intermediate layer 7 may not be provided, and the first joint 21 and the second joint 22 may be bonded together with the movable glass 1 by means of the adhesiveness generated by the hot pressing of the two joints.

[0069] like Figure 6 and Figure 7 As shown, in order to facilitate high-pressure bonding between the first connecting part 21 and the movable glass 1, in some embodiments of the present invention, a mounting groove 24 is formed between the sliding part 23 and the edge portion of the first connecting part 21, that is, there is a gap between the connection position of the sliding part 23 and the first connecting part 21 and the edge end face 13 of the first connecting part 21, such as... Figure 2 As shown, if the mounting groove 24 is not provided, the connection position between the sliding part 23 and the first connecting part 21 is flush with the edge end face of the first connecting part 21. The movable glass 1, the first intermediate layer 6, and the first connecting part 21 are stacked in a sandwich structure. By providing the mounting groove 24, the vacuum sealing ring 5 can be fitted around the sandwich structure, so that the circumferential edge gaps between the movable glass 1, the first intermediate layer 6, and the first connecting part 21 are all located within the sealing cavity 53 of the vacuum sealing ring 5. Then, by connecting the vacuum sealing ring 5 to the vacuuming device, the gas between the movable glass 1, the first intermediate layer 6, and the first connecting part 21 can be extracted. Thus, in a high-temperature and high-pressure chamber, the movable glass 1, the first intermediate layer 6, and the first connecting part 21 can be assembled into one piece. Similarly, when the second connecting part 22 and the second intermediate layer 7 are provided, the circumferential edge gaps between the movable glass 1, the second intermediate layer 7, and the second connecting part 22 are also located within the sealing cavity 53 of the vacuum sealing ring 5. Furthermore, the vacuum sealing ring 5 also serves as a limiting element during the high-pressure assembly process.

[0070] In other embodiments of the present invention, instead of using a vacuum sealing ring 5 around the sandwich structure, the sandwich structure is placed directly on the support structure and some limiting structures are set in the circumferential direction to limit the position of the sandwich structure. Then, it is first sent into a vacuum chamber to evacuate the vacuum, and then the sandwich structure is hot-pressed into a single piece with the help of a mold.

[0071] Implementation Method 2

[0072] like Figure 1 and Figure 3As shown, the present invention also provides a method for manufacturing a guide rail glass structure, which includes the following steps: preparing a glass as a movable glass 1; forming a molding cavity for the movable guide rail 2 by fitting the movable glass 1 with a molding mold of the movable guide rail 2; injecting injection molding material into the molding cavity; and curing the injection molding material to form the movable guide rail 2; wherein, the first connecting part 21 of the movable guide rail 2 is injection molded on one side of the movable glass 1 and stacked with the movable glass 1 to form a sandwich structure. The specific structure, working principle, and beneficial effects of the guide rail glass structure in this embodiment are the same as those in Embodiment 1, and will not be repeated here.

[0073] Implementation Method 3

[0074] like Figure 2 , Figure 4 as well as Figure 5 As shown, the present invention also provides a method for manufacturing a guide rail glass structure. The manufacturing method includes the following steps: preparing a glass as a movable glass 1; injection molding a movable guide rail 2; preparing a first intermediate layer 6; stacking the first intermediate layer 6 between the first joint 21 of the movable guide rail 2 and the movable glass 1 to form a sandwich structure; and using high-pressure lamination to make the first intermediate layer 6 adhesive, thereby joining the first joint 21 and the movable glass 1 together. The guide rail glass structure in this embodiment has the same specific structure, working principle, and beneficial effects as the guide rail glass structure in Embodiment 1, and will not be repeated here.

[0075] like Figure 6 and Figure 7 As shown, in an embodiment of the present invention, the first interlayer 6 is made adhesive by high-pressure lamination to fuse the first joint 21 with the movable glass 1 as a whole. This includes the following steps: placing a vacuum sealing ring 5 around the sandwich structure so that the circumferential edge gap of the sandwich structure is located within the sealing cavity 53 of the vacuum sealing ring 5; connecting the vacuum sealing ring 5 to a vacuuming device for initial vacuuming; placing the sandwich structure in the high-pressure lamination chamber for pressurization, heating, and continued vacuuming to make the first interlayer 6 adhesive and fuse the first joint 21 with the movable glass 1 as a whole; and removing the vacuum sealing ring 5.

[0076] The vacuum sealing ring 5 has two sealing edges 51 arranged opposite to each other and a sealing middle part 52 connecting the two sealing edges 51. The sealing middle part 52 is located around the sandwich structure. One sealing edge 51 is sealed and fitted with the outer side 12 of the movable glass 1, and the other sealing edge 51 is inserted into the sealing groove formed between the sliding part 23 and the edge part of the first joint 21 and fits with the edge part of the first joint 21.

[0077] Implementation Method 4

[0078] like Figures 8 to 12 As shown, the present invention also provides a door glass assembly, including a guide rail glass structure.

[0079] In an embodiment of the present invention, the movable glass 1 is a lift-up glass, and the moving direction is the lifting direction. The movable glass 1 has an inner side 11 facing the inside of the vehicle and an outer side 12 facing the outside of the vehicle. The first connecting part 21 is stacked on the inner side 11 of the movable glass 1. The door glass assembly also includes a fixed glass 3 and a fixed guide rail 4. The outer side 32 of the fixed glass 3 facing the outside of the vehicle is flush with the outer side 12 of the lift-up glass facing the outside of the vehicle. The fixed guide rail 4 is disposed on the inner side 31 of the fixed glass 3 facing the inside of the vehicle along the lifting direction. The sliding part 23 slides with the fixed guide rail 4 along the lifting direction.

[0080] The door glass assembly of the present invention improves the sliding fit accuracy between the movable guide rail 2 and the fixed guide rail 4 by setting a guide rail glass structure, thereby improving the stability of the movement of the movable glass 1 and improving the positional accuracy between the movable glass 1 and the fixed glass 3, ensuring that the outer side 12 of the movable glass 1 is flush with the outer side 32 of the fixed glass 3, thereby helping to reduce the wind resistance of the vehicle.

[0081] Specifically, the fixed guide rail 4 includes an aluminum guide rail 41 disposed on the inner side 31 of the fixed glass 3 and a guide sealing strip 42 installed in the aluminum guide rail.
