The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0043] like Figures 1 to 3 As shown, this embodiment provides a vehicle door sliding glass guide track structure, a vehicle door quarter window assembly, and a vehicle. The vehicle includes a vehicle door quarter window assembly, which includes a fixed glass 1, a connector 2, and a vehicle door sliding glass guide track structure 3. The vehicle door sliding glass guide track structure 3 and the fixed glass 1 are integrated into one body via the connector 2. The connector 2 is an injection-molded structural member or a structural member made of an adhesive material. For example, the adhesive material is a structural adhesive; however, other adhesives may also be used.

[0044] Connector 2 integrates the sliding glass guide structure 3 with the fixed glass 1. In other words, the fixed glass 1, sliding glass guide structure 3, and connector 2 form a single assembly, improving assembly convenience and positioning accuracy of the door corner window assembly. Connector 2, an injection-molded component or one made of an adhesive material, further enhances the ease of integration between the fixed glass 1 and sliding glass guide structure 3, while also reducing costs.

[0045] The door sliding glass guide rail structure 3 includes a connecting portion 31 and a sealing portion 32. The connecting portion 31 can be slidably connected to the sliding glass 4. The connecting portion 31 is a rigid structure, and the sealing portion 32 can abut against the sliding glass 4 to cause the sealing portion 32 to produce elastic deformation. The connecting portion 31 and the sealing portion 32 are integrally formed through a composite extrusion process or an injection molding process, and the materials used in different parts of the connecting portion 31 are the same.

[0046] The door sliding glass guide rail structure 3 of this embodiment supports and guides the movement of the sliding glass 4 through the connecting portion 31 of the rigid structure, and ensures the sealing of the sliding glass 4 through the sealing portion 32 that can produce elastic deformation; at the same time, the connecting portion 31 and the sealing portion 32 are integrally formed through a composite extrusion process or an injection molding process, and the materials used in different parts of the connecting portion 31 are the same. That is to say, compared with the existing technology, the connecting portion 31 does not need to use a metal frame, which can not only greatly improve the lightweight effect of the door corner window assembly, but also reduce the cost.

[0047] Optionally, the hardness of the connecting portion 31 ranges from 50SHD to 90SHD. On the one hand, the hardness of the connecting portion 31 can meet the requirements to ensure the stability and reliability of the connecting portion 31 in supporting the movable glass 4 , and on the other hand, it is conducive to further reducing costs.

[0048] Illustratively, the hardness of the connection portion 31 may be any value between 50 SHD and 90 SHD, for example, the hardness of the connection portion 31 may be 50 SHD, 55 SHD, 60 SHD, 65 SHD, 70 SHD, 75 SHD, 80 SHD, 85 SHD or 90 SHD.

[0049] Optionally, the hardness of the sealing portion 32 is in the range of 50SHA-75SHA, which can improve the sealing effect of the sealing portion 32 on the one hand, and help to further reduce costs on the other hand.

[0050] Illustratively, the hardness of the sealing portion 32 may be any value between 50 SHA and 75 SHA. For example, the hardness of the sealing portion 32 may be 50 SHA, 55 SHA, 60 SHA, 65 SHA, 70 SHA, or 75 SHA.

[0051] Furthermore, the connection portion 31 is made of TPV material (i.e., thermoplastic vulcanizate, the full name in English is Thermoplastic Vulcanizate, abbreviated as TPV), which is beneficial to improving the stiffness, reliability and service life of the connection portion 31 on the one hand, and on the other hand, it is convenient to further achieve lightweighting and reduce costs. Of course, as an alternative, the connection portion 31 can also be made of PP material (i.e., polypropylene, the full name in English is Polypropylene, abbreviated as PP) or modified PP material. It should be noted that the TPV material, PP material or modified PP material used in the connection portion 31 are all materials in the prior art. For example, the modified PP material includes glass fiber reinforced PP material.

[0052] Furthermore, the sealing portion 32 is made of TPV material, which is beneficial to improving the sealing effect and reliability of the sealing portion 32 and extending the service life of the sealing portion 32. It also facilitates the sealing portion 32 and the connecting portion 31 to be integrally formed through a composite extrusion process, thereby facilitating the industrial production of the vehicle door movable glass guide rail structure 3.

[0053] In this embodiment, the movable glass 4 is slidably connected to the connecting portion 31 via the adapter 5. Specifically, one end of the adapter 5 is slidably connected to the connecting portion 31, and the other end is fixedly connected to the movable glass 4, thereby improving the connection convenience between the movable glass 4 and the connecting portion 31.

[0054] Optionally, the sealing portion 32 includes a first sealing branch 321 , and the first sealing branch 321 is sandwiched between the fixed glass 1 and the movable glass 4 , thereby sealing the gap between the fixed glass 1 and the movable glass 4 to ensure a sealing effect.

[0055] Furthermore, the sealing portion 32 includes a second sealing branch 322, which is capable of abutting the inner side of the sliding glass 4. Furthermore, the first sealing branch 321 and the second sealing branch 322 are located on either side of the adapter 5. The inner side of the sliding glass 4 is the side of the sliding glass 4 facing the interior of the vehicle cabin. This arrangement ensures the sealing of the sliding glass 4 while preventing interference between the adapter 5 and the first and second sealing branches 321, 322, thereby improving the reliability and assembly convenience of the door quarter window assembly.

[0056] Furthermore, two second sealing branches 322 are provided, and the two second sealing branches 322 are arranged at intervals, wherein one second sealing branch 322 abuts against the connection between the adapter 5 and the movable glass 4, and the second sealing branch 322 is located between the first sealing branch 321 and the other second sealing branch 322.

[0057] Optionally, the first sealing branch 321 is a lip-shaped structure, thereby improving the sealing effect.

[0058] Optionally, the second sealing branch 322 is a lip-shaped structure, thereby improving the sealing effect.

[0059] Optionally, a first lubricating layer 33 is provided at the contact point between the sealing portion 32 and the movable glass 4 , thereby improving the smoothness of movement of the movable glass 4 , improving the user experience, and also improving the wear resistance and service life of the sealing portion 32 .

[0060] Specifically, a first lubricating layer 33 is provided at the contact point between the first sealing branch 321 and the movable glass 4, and at the contact point between the second sealing branch 322 and the movable glass 4. Exemplarily, the first lubricating layer 33 is a fleece layer, a polytetrafluoroethylene (PTFE) layer, or an ultra-high molecular weight polyethylene (UHMWPE) layer.

[0061] Optionally, a second lubricating layer 34 is provided at the contact point between the connecting portion 31 and the movable glass 4, thereby improving the smoothness of the movement of the movable glass 4, enhancing the user experience, and increasing the wear resistance and service life of the connecting portion 31. Exemplarily, the second lubricating layer 34 is a fleece layer, a polytetrafluoroethylene layer, or an ultra-high molecular weight polyethylene layer.

[0062] In this embodiment, the movable glass 4 is connected to the connecting portion 31 by sliding along the first direction.

[0063] Optionally, the connecting portion 31 includes a first limiting structure that restricts movement of the movable glass 4 along the second direction. Furthermore, the movable glass 4 can move along a third direction relative to the connecting portion 31. The connecting portion 31 also includes a second limiting structure that limits the distance the movable glass 4 can move along the third direction. The first direction, the second direction, and the third direction are perpendicular to each other. This arrangement improves the stability and smoothness of the movement of the movable glass 4, enhancing the user experience.

[0064] In other embodiments, the connecting portion 31 may further include a second limiting structure, and the second limiting structure can limit the movable glass 4 from moving along the third direction.

[0065] Specifically, the connecting portion 31 is provided with a chute 311, and one end of the adapter 5 is provided with a slider 51. The slider 51 is slidably disposed within the chute 311 along a first direction. Furthermore, the chute 311 includes two first sidewalls 3111 disposed opposite each other along a second direction. The two first sidewalls 3111 respectively abut against the two sides of the slider 51 along the second direction. The two first sidewalls 3111 constitute a first retaining structure. Furthermore, the chute 311 also includes a second sidewall 3112 and an opening disposed opposite each other along a third direction. The connecting portion 31 also includes a retaining protrusion disposed at the opening. The second sidewall 3112 and the retaining protrusion constitute a second retaining structure. Specifically, the slider 51 is capable of moving between the second sidewall 3112 and the retaining protrusion. When the slider 51 abuts the second sidewall 3112 or the retaining protrusion, the slider 51 is retained by the second sidewall 3112 or the retaining protrusion. Exemplarily, the limiting protrusion includes two limiting hooks 312, and the two limiting hooks 312 are respectively located on both sides of the rotating member.

[0066] Optionally, the connecting portion 31 is bent into shape by a stretch bending process or a press bending process, which not only improves the rigidity of the connecting portion 31, but also improves the matching accuracy of the curvature and arc of the connecting portion 31 and the movable glass 4, thereby helping to improve the assembly convenience and service life of the vehicle door corner window assembly.

[0067] Optionally, the sealing portion 32 is bent into shape by a stretch bending process or a press bending process, thereby improving the matching accuracy of the sealing portion 32 with the fixed glass 1 and the movable glass 4, thereby helping to improve the sealing effect and improve the assembly convenience and service life of the vehicle door corner window assembly.

[0068] It should be noted that the bending process includes hot bending and cold bending, and the methods of hot bending and cold bending are both existing technologies. In other words, the connecting portion 31 can be bent and formed by hot bending or cold bending. The sealing portion 32 can also be bent and formed by hot bending or cold bending.

[0069] Specifically, after the connecting portion 31 and the sealing portion 32 are integrally formed through a composite extrusion process or an injection molding process, the connecting portion 31 and the sealing portion 32 are bent into shape through a stretch bending process or a press bending process.

[0070] Optionally, on the outside of the vehicle door, the fixed glass 1, the first sealing branch 321 and the movable glass 4 are arranged flush, which is beneficial to reducing wind resistance, thereby improving the NVH performance and aesthetics of the vehicle, and making the door corner window assembly suitable for a zero-order difference door system.

[0071] Alternatively, as Figure 2 As shown, the door quarter window assembly also includes a decorative member 6, which is disposed around the side of the connecting portion 31 facing away from the movable glass 4. The decorative member 6 is provided separately from the connecting portion 31 and fixedly connected, thereby enhancing the aesthetics of the door system. For example, the decorative member 6 is fixedly connected to the connecting portion 31 using glue or tape (such as 3M tape), which is convenient and low-cost.

[0072] Optionally, the decorative member 6 is a metal plate. For example, the metal plate is an aluminum plate, which is formed by bending after extrusion. Of course, the metal plate can also be made of a stainless steel plate through processes such as rolling and stamping.

[0073] Optionally, a paint layer is provided on the surface of the decorative element 6 to improve the aesthetics of the decorative element 6 .

[0074] Of course, if Figure 3As shown, the decorative member 6 can also be integrally formed with the connecting portion 31 and the sealing portion 32 through a composite extrusion process or an injection molding process. In other words, the decorative member 6, the connecting portion 31, and the sealing portion 32 are integrally formed through a composite extrusion process or an injection molding process, which is beneficial for improving production efficiency and the connection reliability of the decorative member 6 and the connecting portion 31.

[0075] Optionally, the decorative part 6 adopts MCPP material (i.e., aluminum-plated grade CPP, the full name in English is Metalize CPP, abbreviated as MCPP), TPV material, TPE material (i.e., thermoplastic elastomer, the full name in English is Thermoplastic Elastomer, abbreviated as TPE) or TPS material (i.e., thermoplastic styrene elastomer, the full name in English is Thermoplastic Styrenic-based Polymer, abbreviated as TPS), which not only improves the wear resistance of the decorative part 6, but also helps to reduce costs.

[0076] Optionally, the side of the decorative member 6 facing away from the connection portion 31 may be provided with a high-gloss or matte surface, thereby enhancing the aesthetics of the decorative member 6. Specifically, the decorative member 6 may be made of MCPP, TPV, TPE, or TPS material through a composite extrusion process, resulting in a high-gloss or matte finish on the side of the decorative member 6 facing away from the connection portion 31. Exemplarily, the high-gloss or matte surface is black. Of course, other colors are possible, and are not limited here. The side of the decorative member 6 facing away from the connection portion 31 is the side of the decorative member 6 that is visible inside the vehicle cabin.

[0077] Alternatively, as Figure 2 As shown, when the decorative member 6 and the connecting portion 31 are separately arranged and fixedly connected, the decorative member 6 is also arranged around the outside of the connecting member 2. That is, by surrounding the connecting portion 31 and the connecting member 2 at the same time, the appearance of the vehicle cabin can be improved.

[0078] Alternatively, as Figure 3 As shown, when the decorative part 6 and the connecting part 31 are integrally formed through a composite extrusion process, one end of the decorative part 6 is connected to the connecting part 2, thereby forming a continuous surface on the inner side of the door corner window assembly, thereby improving the appearance of the interior of the vehicle cabin.

[0079] Alternatively, as Figure 3 As shown, when the decorative part 6 and the connecting part 31 are integrally formed through a composite extrusion process, the surface of the decorative part 6 facing away from the connecting part 31 is flush with the outer surface of the connecting part 2, thereby making the inner side surface of the door corner window assembly a smooth surface, thereby improving the appearance of the interior of the vehicle cabin.

[0080] It should be noted that the door sliding glass guide rail structure 3 of this embodiment can be arranged on the A-pillar of the vehicle, and can also be arranged on the C-pillar of the vehicle.

[0081] For example, the door sliding glass guide rail structure 3 is formed as one piece by a composite extrusion process of a connecting part 31 made of TPV material with a hardness of 70SHD and a sealing part 32 made of TPV material with a hardness of 50SHA, and then bent by a stretch bending process or a press bending process to make the door sliding glass guide rail structure 3 better match the movable glass 4. Compared with the existing technology, not only can the door sliding glass guide rail structure 3 have sufficient rigidity and sealing, but it can also greatly reduce the weight and cost of the door sliding glass guide rail structure 3.
