[0026] The embodiments of the utility model are described in detail below, the examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout the description.The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as limiting the utility model.

[0027] As Figures 1 to 2 The embodiment provides a bound corner window structure for zero-order difference vehicle door system, which comprises fixed corner window glass 1, guide rail structural member 2, bound member 3 and mobile glass assembly 4.The fixed corner window glass 1 can be installed on the door panel;The guide rail structural member 2 has a limiting groove 21, a first limiting structure 22 and a second limiting structure 23, the first limiting structure 22 and the second limiting structure 23 are arranged on the side wall of the limiting groove 21;The bound member 3 connects the guide rail structural member 2 and the fixed corner window glass 1;The mobile glass assembly 4 comprises a mobile glass main body 41 and a sliding member 42, one end of the sliding member 42 is connected with the mobile glass main body 41, the other end of the sliding member 42 is located in the limiting groove 21, the limiting groove 21 can limit the sliding member 42 in the first direction, the first limiting structure 22 and the second limiting structure 23 can limit the sliding member 42 in the second direction, and the first direction and the second direction are perpendicular;Wherein, the fixed corner window glass 1, the guide rail structural member 2 and the bound member 3 are integrally formed by injection molding. Figure 2 As shown in the figure, the Y direction is the first direction, and the X direction is the second direction.

[0028] The corner window structure for a zero-step differential door system of this invention integrates the fixed corner window glass 1, guide rail structure 2, and edge-sealing component 3 into a single injection-molded structure. This integrated design reduces the number of injection molding processes, decreases logistics and packaging costs associated with parts transfer, and effectively improves installation efficiency. Compared to traditional solutions requiring two installation steps for two different parts, the new solution requires only one process and station, eliminating the need for adjustment and matching, thus reducing installation time and improving assembly precision. Furthermore, by setting the first limiting structure 22 and the second limiting structure 23, the sliding component 42 can be simultaneously limited in the second direction, while the limiting groove 21 can limit it in the first direction, further ensuring the stability of the sliding component 42 during lifting and lowering. This corner window structure for a zero-step differential door system effectively solves the problem in existing door system corner window structures where multiple separate parts need to be installed during assembly, leading to assembly difficulties and high production and time costs.

[0029] It should be noted that, Figure 1 and Figure 2 The image shows a rear door, but the same principle applies to the front doors. This invention meets the needs of OEMs to reduce components and assembly processes, as well as improve fit and appearance, while simultaneously reducing costs and achieving a lightweight design.

[0030] In some embodiments, such as Figure 2 As shown, the first limiting structure 22 is configured as a first anti-detachment hook, wherein one end of the first anti-detachment hook is connected to one side wall of the limiting groove 21, and the other end of the first anti-detachment hook faces the limiting groove 21. With this configuration, the first anti-detachment hook can limit the sliding member 42 in the second direction. Similarly, the second limiting structure 23 can also be configured as a second anti-detachment hook, wherein one end of the second anti-detachment hook is connected to the other side wall of the limiting groove 21, and the other end of the second anti-detachment hook faces the limiting groove 21. With this configuration, the second anti-detachment hook can also limit the sliding member 42 in the second direction.

[0031] Alternatively, in another embodiment not shown in the figure, the first limiting structure 22 and the second limiting structure 23 may both be limiting protrusions, which can limit the sliding member 42 in the second direction.

[0032] In this embodiment, the guide rail structure 2 includes a guide rail frame 24 and a guide rail sealing strip 25. The guide rail frame 24 and the guide rail sealing strip 25 are an integral structure formed by extrusion and bending. This design, through extrusion molding, allows the guide rail frame 24 and the guide rail sealing strip 25 to be integrated, reducing the number of injection molding processes, reducing logistics and packaging costs during parts transfer, and effectively improving installation efficiency. Simultaneously, the bending process achieves matching curvature and arc between the guide rail structure 2 and the movable glass assembly 4, while also ensuring sufficient strength for the sliding member 42 when moving within the limiting groove 21. The edge-sealing member 3 connects the guide rail sealing strip 25 to the fixed corner window glass 1.

[0033] Furthermore, to match the fixed corner window glass 1 and the movable glass assembly 4, the guide rail sealing strip 25 includes a first sealing section 251, a U-shaped sealing section 252, and a second sealing section 253 connected in sequence. One side of the first sealing section 251 seals the end of the fixed corner window glass 1, providing a better seal. Simultaneously, the other end of the first sealing section 251 seals one side of the movable glass body 41. The first sealing section 251 is substantially flush with the outer surfaces of both the fixed corner window glass 1 and the movable glass assembly 4, ensuring a good vehicle appearance while reducing wind resistance and noise, thus ensuring NVH performance (Noise, Vibration, and Harshness). The U-shaped sealing section 252 has a limiting groove 21, which, through the second sealing section 253, seals one end of the sliding member 42 and the other side of the movable glass body 41, thereby sealing the movable glass assembly 4.

[0034] Specifically, the first sealing section 251 includes a first connecting section 2511 and a first sealing lip 2512 that are connected to each other. The first connecting section 2511 and the U-shaped sealing section 252 are connected, and the side of the first connecting section 2511 opposite to the first sealing lip 2512 has a sealing groove, wherein the end of the fixed corner window glass 1 is located in the sealing groove, thereby sealing the end of the fixed corner window glass 1, and the first sealing lip 2512 seals one side of the movable glass body 41.

[0035] In this embodiment, the first limiting structure 22 and the second limiting structure 23 are respectively set on the two opposite inner walls of the U-shaped sealing section 252 and located at the opening of the limiting groove 21. This setting can limit the two ends of the sliding member 42, thereby improving the limiting effect and ensuring the positional stability of the sliding member 42 during the lifting process.

[0036] The outer walls of the U-shaped sealing section 252 and part of the first sealing section 251 are connected to the fixed corner window glass 1 via the edge-sealing piece 3. This arrangement increases the contact area between the fixed corner window glass 1 and the guide rail sealing strip 25, thereby ensuring the connection strength between the fixed corner window glass 1 and the guide rail sealing strip 25.

[0037] Specifically, the second sealing section 253 includes a second connecting section 2531 and a second sealing lip 2532 and a third sealing lip 2533 disposed on the second connecting section 2531. The second connecting section 2531 and the U-shaped sealing section 252 are connected, with the second sealing lip 2532 sealing one end of the sliding member 42, while the third sealing lip 2533 seals the other side of the movable glass body 41. This allows the second sealing section 253 to simultaneously seal one end of the sliding member 42 and the other side of the movable glass body 41. Furthermore, the second sealing section 253 is an integrated structure, reducing the number of injection molding processes, reducing logistics and packaging costs associated with parts transfer, and effectively improving installation efficiency.

[0038] In this embodiment, the sliding member 42 includes a sliding block 421 and a connecting block 422 connected to each other. The sliding block 421 is located in the limiting groove 21, and the connecting block 422 is connected to the movable glass body 41. With this configuration, the limiting groove 21 can limit the sliding block 421 in a first direction, and the first limiting structure 22 and the second limiting structure 23 can limit the sliding block 421 in a second direction, thereby ensuring the stability of the sliding member 42 during the lifting and lowering process.

[0039] Specifically, the edge banding component 3 is made of rubber or a thermoplastic elastomer. The edge banding component 3 includes, but is not limited to, EPDM, TPS, or TPV. EPDM (ethylene propylene diene monomer) is a copolymer of ethylene, propylene, and a small amount of non-conjugated diene; it is a type of ethylene propylene rubber and possesses heat resistance, weather resistance, and other aging resistance properties. TPS (thermoplastic styrene polymer) is a thermoplastic elastomer with good strength and elasticity. TPV (thermoplastic vulcanizate) is a material that combines the elasticity of rubber with the processability of plastics, performing excellently in high-temperature and oil-resistant environments and exhibiting good aging resistance.

[0040] One side of the edge-sealing piece 3 is connected to the inner wall of the fixed corner window glass 1, and the other side is connected to the outer wall of the U-shaped sealing section 252 and part of the first sealing section 251.

[0041] This embodiment also provides a vehicle including the edge-sealing corner window structure for a zero-step differential door system described above. The vehicle using this invention integrates the fixed corner window glass 1, guide rail structure 2, and edge-sealing component 3 into a single injection-molded structure. This integrated design reduces the number of injection molding processes, decreases logistics and packaging costs associated with parts transfer, and effectively improves installation efficiency. Compared to the traditional solution requiring two installation steps for two different parts, the new solution requires only one process and station, eliminating the need for installation and adjustment adjustments, thus reducing installation time and improving assembly accuracy. Furthermore, by setting the first limiting structure 22 and the second limiting structure 23, the sliding component 42 can be simultaneously limited in the second direction, and the limiting groove 21 can also limit it in the first direction, further ensuring the stability of the sliding component 42 during lifting and lowering. The vehicle using this invention effectively solves the problem in the prior art where the edge-sealing corner window structure of a door system requires the installation of multiple separate parts, leading to assembly difficulties and high production and time costs.

[0042] Optionally, this invention is not limited to glass type, but is also applicable to tempered glass and laminated glass.

[0043] Optionally, this utility model is not limited to the appearance of fixed corner window glass, but also applies to the appearance of A / C pillars with plastic trim panels.

[0044] Optionally, this utility model is not limited to integrated decorative panels and fixed corner windows, but can also integrate internal water cutters and external water cutters, or is not limited to integrating a combination of one or more of these solutions.

[0045] The advantages of this utility model are as follows:

[0046] 1. Improved installation efficiency: This utility model integrates the zero-step difference door system design with guide rail structure and fixed corner window structure through injection molding edge banding process, reducing the number of door system components assembled by the OEM and effectively improving the installation efficiency of the door system components assembled by the OEM.

[0047] 2. System tolerance and matching: By using the injection molding edge-wrapping process, the matching tolerance problem between the guide groove C-pillar guide rail sealing strip and the C-pillar fixed corner window in the existing technology has been solved through mold precision and process implementation, thereby improving the system tolerance.

[0048] 3. Superior appearance: The zero-step difference system design incorporates guide rail structure and fixed corner window structure through injection molding edge binding process, which enhances the overall texture of the structure.

[0049] 4. Performance Improvement: Compared with the traditional method of matching two parts around the fixed glass, which requires sealing with foam, has high requirements for installation and matching accuracy, and the performance of foam will be lost after aging, this utility model integrates the guide rail structure and the fixed corner window glass into one part. The matching edges of the fixed corner window glass are all covered by edge-sealing parts, ensuring the vehicle's NVH and airtight performance.

[0050] 5. Door system cost optimization: This utility model integrates the guide rail structure and the fixed corner window glass into one part, which reduces the number of injection molding processes, reduces the logistics and packaging costs of parts transfer, and significantly improves the time required for integrated installation and adjustment of the whole vehicle.
