Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, and in particular to a corner window structure for a zero-step differential door system and a vehicle thereof. Background Technology
[0002] Currently, the side windows of a vehicle include components such as the B-pillar trim, guide channels, and fixed corner windows. In traditional structures, the fixed corner windows are usually assembled onto the door sheet metal first, followed by the installation of the glass guide channel sealing strips. During assembly, the B-pillar and C-pillar sealing strips of the guide channel need to be suspended. After the fixed corner windows are installed, the B-pillar and C-pillar sealing strips of the guide channel are snapped into place. However, the matching state of each component needs to be adjusted during assembly. Since the guide channel C-pillar corner, C-pillar sealing strip, guide channel sealing strip, and fixed corner windows are separate parts, the manufacturing process is complicated during assembly, requiring separate packaging and logistics. The final assembly process needs to be adjusted, increasing production and time costs. Furthermore, the guide channel sealing strips wear significantly after prolonged use, affecting the vehicle's NVH and airtightness performance. Utility Model Content
[0003] The purpose of this utility model is to provide a corner window structure and vehicle for a zero-step differential door system, so as to solve the problem that the guide groove sealing strip of the existing corner window structure is prone to wear after long-term use, which affects the vehicle's NVH and airtight performance.
[0004] On one hand, this utility model provides a corner window structure for a zero-step differential door system. This corner window structure includes: a fixed corner window glass, capable of being installed on the door sheet metal; a guide rail structure, including a guide rail frame and a guide rail sealing strip, the guide rail frame and the guide rail sealing strip being an integral structure formed by extrusion bending; a movable glass assembly, including a movable glass body and a sliding member, one end of the sliding member being connected to the movable glass body, and the other end of the sliding member being limited and engaged with the guide rail sealing strip, the guide rail sealing strip sealing one side of the movable glass body; and a edging component, including an edging body, an injection-molded sealing lip, and a wear-resistant structure, the edging body and the injection-molded sealing lip being an integral structure formed by injection molding, the wear-resistant structure being disposed on the outer surface of the injection-molded sealing lip, the edging body connecting the guide rail sealing strip and the fixed corner window glass, and the wear-resistant structure abutting against the other side of the movable glass body.

[0007] As an optional technical solution for the edge-sealing corner window structure of a zero-step differential door system, the guide rail sealing strip includes a first sealing section, a U-shaped sealing section and a second sealing section connected in sequence. The first sealing section and part of the U-shaped sealing section are connected to the edge-sealing body. The other end of the sliding member is limited and matched with the U-shaped sealing section. The second sealing section seals one side of the moving glass body.
[0008] As an optional technical solution for the edge-sealing corner window structure of the zero-step differential door system, the first sealing section has an anti-adhesion structure.

The lip support structure can support the deformed injection-molded sealing lip.
[0010] As an optional technical solution for the edge-sealing corner window structure of a zero-step differential door system, the U-shaped sealing section has a limiting groove and a first limiting structure and a second limiting structure respectively disposed on the side wall of the limiting groove. The other end of the sliding member is located in the limiting groove. The limiting groove can limit the sliding member in a first direction, and the first limiting structure and the second limiting structure can limit the sliding member in a second direction. The first direction and the second direction are perpendicular.
[0011] As an optional technical solution for the edge-sealing corner window structure of the zero-step differential door system, the first limiting structure is a first anti-detachment hook.

[0016] The beneficial effects of this utility model are as follows:
[0017] This utility model provides a corner window structure for a zero-step differential door system. The corner window structure includes a fixed corner window glass, a guide rail structure, a movable glass assembly, and a corner protector. The guide rail structure includes a guide rail frame and a guide rail sealing strip; the movable glass assembly includes a movable glass body and a sliding component; and the corner protector includes a corner protector body, an injection-molded sealing lip, and a wear-resistant structure. In this corner window structure for a zero-step differential door system, the corner protector body and the injection-molded sealing lip are integrally molded. This design provides good support when the injection-molded sealing lip is compressed. Simultaneously, the wear-resistant structure is located on the outer surface of the injection-molded sealing lip and abuts against the other side of the movable glass body. This further ensures that the injection-molded sealing lip is not easily worn after prolonged use, effectively improving the wear resistance and sealing performance of the corner protector.

Furthermore, the guide rail frame and guide rail sealing strip are an integrated structure formed by extrusion bending, while the edge-wrapping body and injection-molded sealing lip are an integrated structure formed by injection molding. Through the integrated design structure, the number of injection molding processes is reduced, the logistics and packaging costs of parts transfer are reduced, and the installation efficiency and assembly accuracy are effectively improved.

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0032] like Figure 1 As shown, this embodiment provides a corner window structure for a zero-step differential door system. The corner window structure for a zero-step differential door system includes a fixed corner window glass 1, a guide rail structure 2, a movable glass assembly 3, and a corner sealing component 4. The fixed corner window glass 1 can be installed on the door sheet metal; the guide rail structure 2 includes a guide rail frame 21 and a guide rail sealing strip 22, which are integral structures formed by extrusion bending; the movable glass assembly 3 includes a movable glass body 31 and a sliding member 32, one end of which is connected to the movable glass body 31, and the other end of which is limited and cooperates with the guide rail sealing strip 22, which seals one side of the movable glass body 31; the edge-wrapping component 4 includes an edge-wrapping body 41, an injection-molded sealing lip 42, and a wear-resistant structure 43, which are integral structures formed by injection molding, and the wear-resistant structure 43 is disposed on the outer surface of the injection-molded sealing lip 42. The edge-wrapping body 41 connects the guide rail sealing strip 22 and the fixed corner window glass 1, and the wear-resistant structure 43 abuts against the other side of the movable glass body 31.
[0033] The corner window structure for a zero-step differential door system of this invention features an integrated edge-wrapping body 41 and injection-molded sealing lip 42. This design provides excellent support for the injection-molded sealing lip 42 under pressure. Furthermore, a wear-resistant structure 43 is placed on the outer surface of the injection-molded sealing lip 42, abutting against the other side of the movable glass body 31. This further ensures that the injection-molded sealing lip 42 is not easily worn after prolonged use, effectively improving the wear resistance and sealing performance of the edge-wrapping component 4. This solves the problem in existing edge-wrapping corner window structures where the guide groove sealing strip is prone to wear after prolonged use, affecting the vehicle's NVH and airtightness performance. Moreover, the guide rail frame 21 and guide rail sealing strip 22 are an integrated structure formed by extrusion bending. This integrated design reduces the number of injection molding processes, decreases logistics and packaging costs for parts transfer, and effectively improves installation efficiency and assembly accuracy.
[0034] It should be noted that the edge-wrapping corner window structure for zero-step differential door systems of this utility model can be applied to both rear and front doors. This utility model meets the needs of OEMs to reduce components, assembly processes, and improve matching and appearance, while simultaneously reducing costs and achieving lightweight design. NVH is an abbreviation for Noise, Vibration, and Harshness.
[0035] In some embodiments, the wear-resistant structure 43 includes, but is not limited to, PE film tape, PP film tape, or flocked tape. All of these materials possess high wear resistance, which can improve the wear resistance and sealing effect of the edge-sealing component 4.
[0036] Optionally, after testing and verification, the PE film tape or PP film tape can be made with a thickness of 0.1mm-0.3mm, which can better guarantee performance and this structure can better ensure appearance consistency.
[0037] like Figure 2 As shown, in the second embodiment of this utility model, the edging body 41 wraps around one end of the fixed corner window glass 1 and is flush with the side of the fixed corner window glass 1 that is away from the guide rail frame 21. This arrangement can further improve the NVH performance of the vehicle.
[0038] In this embodiment, the guide rail sealing strip 22 includes a first sealing section 221, a U-shaped sealing section 222, and a second sealing section 223 connected in sequence. The first sealing section 221 and part of the U-shaped sealing section 222 are connected to the edge-wrapping body 41. The other end of the sliding member 32 is engaged with the U-shaped sealing section 222 to ensure stable sliding of the sliding member 32 without detachment. The second sealing section 223 seals one side of the moving glass body 31, thus achieving a sealing effect on the moving glass assembly 3.
[0039] Furthermore, the first sealing segment 221 has an anti-adhesion structure 2211. The anti-adhesion structure 2211 is positioned on the side of the first sealing segment 221 facing the injection-molded sealing lip 42, and it can abut against the deformed injection-molded sealing lip 42. This arrangement ensures that the injection-molded sealing lip 42 contacts the anti-adhesion structure 2211 after deformation, effectively preventing adhesion between the injection-molded sealing lip 42 and the first sealing segment 221.
[0040] Optionally, the anti-adhesion structure 2211 is a wave-like structure.
[0041] In this embodiment, the first sealing segment 221 has a lip support structure 2212. The lip support structure 2212 is located on the side of the first sealing segment 221 facing the injection-molded sealing lip 42, and on the side of the anti-adhesion structure 2211 facing the U-shaped sealing segment 222. The lip support structure 2212 can support the deformed injection-molded sealing lip 42. This arrangement allows the deformed injection-molded sealing lip 42 to contact the lip support structure 2212, thereby providing support and improving sealing performance.
[0042] In some embodiments, the U-shaped sealing section 222 has a limiting groove 2221 and a first limiting structure 2222 and a second limiting structure 2223 respectively disposed on the sidewall of the limiting groove 2221. The other end of the sliding member 32 is located in the limiting groove 2221. The limiting groove 2221 can limit the sliding member 32 in a first direction, and the first limiting structure 2222 and the second limiting structure 2223 can limit the sliding member 32 in a second direction. The first direction and the second direction are perpendicular. By setting the first limiting structure 2222 and the second limiting structure 2223, the sliding member 32 can be limited in the second direction at the same time, and the limiting groove 2221 can limit it in the first direction, further ensuring the stability of the sliding member 32 during the lifting and lowering process.
[0043] Furthermore, the first limiting structure 2222 includes, but is not limited to, a first anti-detachment hook, wherein one end of the first anti-detachment hook is connected to one side wall of the limiting groove 2221, and the other end of the first anti-detachment hook faces the limiting groove 2221. The first anti-detachment hook can limit the sliding member 32 in the second direction, thereby ensuring that the sliding member 32 will not detach from the limiting groove 2221.
[0044] Similarly, the second limiting structure 2223 includes, but is not limited to, a second anti-detachment barb. The second anti-detachment barb can limit the sliding member 32 in the second direction, thereby ensuring that the sliding member 32 will not detach from the limiting groove 2221.
[0045] Alternatively, in another embodiment not shown in the figure, the first limiting structure 2222 and the second limiting structure 2223 may both be limiting protrusions, which can limit the sliding member 32 in the second direction.
[0046] like Figure 3 As shown, in the third embodiment of this utility model, the edge-binding body 41 is made of a self-lubricating wear-resistant material, which can improve the service life of the edge-binding body 41. The self-lubricating wear-resistant material is a functional material that reduces friction and wear by using solid lubricants (such as graphite, molybdenum disulfide, polytetrafluoroethylene, etc.), and has the characteristics of low friction coefficient, high temperature resistance, and corrosion resistance.
[0047] The injection-molded sealing lip 42 is formed through an injection-molded sealing structure, which achieves a consistent appearance and ensures better vehicle NVH performance.
[0048] In some embodiments, the corner window structure for the zero-step differential door system further includes a decorative strip 5, which is adhered to or snapped onto the outer surface of the guide rail sealing strip 22.
[0049] Furthermore, the decorative strip 5 is made of plastic or metal. The decorative strip 5 is fixed by tape or clips to the outer surface of the guide rail sealing strip 22. The material of the decorative strip 5 can be plastic injection molded and then painted or coated, or it can be metal material stainless steel rolled or aluminum extruded, bent and then painted or powder coated.
[0050] like Figure 4As shown, in the fourth embodiment of this utility model, there is a distance between the side of the first sealing section 221 facing away from the guide rail frame 21 and the side of the fixed corner window glass 1 facing away from the guide rail frame 21. The first sealing section 221 is located on the side of the fixed corner window glass 1 facing the guide rail frame 21. This arrangement shortens the distance between the fixed corner window glass 1 (cut edge position) and the first sealing section 221, thereby enhancing the cross-sectional strength. Furthermore, after the first sealing section 221 is deformed by the fixed corner window glass 1, the edge-wrapping part 4 forms a good fit with the fixed corner window glass 1, thereby achieving a concealed first sealing section 221, ensuring both appearance and performance.
[0051] This embodiment also provides a vehicle including the edge-sealing corner window structure for a zero-step differential door system described above. In the vehicle using this invention, the edge-sealing body 41 and the injection-molded sealing lip 42 are integrally injection-molded structures. This design allows the injection-molded sealing lip 42 to provide good support when compressed. Simultaneously, a wear-resistant structure 43 is disposed on the outer surface of the injection-molded sealing lip 42, abutting against the other side of the movable glass body 31. This further ensures that the injection-molded sealing lip 42 is not easily worn after prolonged use, effectively improving the wear resistance and sealing effect of the edge-sealing component 4. This solves the problem in the prior art where the guide groove sealing strip of the edge-sealing corner window structure is prone to wear after prolonged use, affecting the vehicle's NVH and airtightness performance. Furthermore, the guide rail frame 21 and the guide rail sealing strip 22 are integrally extruded and bent. This integrated design reduces the number of injection molding processes, reduces logistics and packaging costs during parts transfer, and effectively improves installation efficiency and assembly accuracy.
[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
