[0001] This utility model relates to the field of car door glass guide rail technology, and in particular to a glass guide rail assembly, a car door, and a vehicle. Background Technology
[0002] The guide rails for the car door's power windows provide a channel for the glass to slide, and the lower guide rail inside the door provides structural support for the glass's lifting and lowering. Existing guide rails are generally integral, requiring workers to lift the product higher and then insert it into the door sheet metal. Furthermore, since the door glass is pre-assembled, the guide rails are prone to assembly difficulties during the downward assembly process, considering both product tolerances and assembly tolerances.
[0003] In related technologies, the assembly difficulty is reduced by segmenting the guide rail and pre-assembling the lower guide rail inside the lower guide rail. However, since the lower guide rail is pre-installed in the lower guide rail, it will be moved by the glass during the glass lifting process, which may cause abnormal noise. Utility Model Content
[0004] The purpose of this utility model is to provide a glass guide rail assembly, a car door, and a vehicle. The glass guide rail assembly is easy to assemble, and the guide rail will not be moved by the glass during the glass lifting process, thus avoiding the risk of abnormal noise.

[0034] Example 1:
[0035] Firstly, please refer to Figures 1 to 6 This embodiment provides a glass guide rail assembly, including: a lower guide rail 1, a lower guide rail strip 2, an upper guide rail strip 3, and a limiting structure 4. The lower guide rail 1 has a mounting groove 11, and the lower guide rail strip 2 is inserted into the mounting groove 11. The side of the lower guide rail strip 2 away from the groove wall of the mounting groove 11 has a guide groove 21, which extends along the length direction of the mounting groove 11, and the groove wall of the guide groove 21 is used to slide with a glass slider 5. A portion of the upper guide rail strip 3 is located in the mounting groove 11 of the lower guide rail 1, and the other portion of the upper guide rail strip 3 is used to be installed in a decorative panel 6. The limiting structure 4 includes a limiting block 41 disposed on one of the lower guide rail 1 and the lower guide rail strip 2, and a limiting groove 42 disposed on the other of the lower guide rail 1 and the lower guide rail strip 2. The limiting groove 42 extends along the length direction perpendicular to the mounting groove 11, and the limiting block 41 is located in the limiting groove 42 to limit the relative position of the lower guide rail 1 and the lower guide rail strip 2.
[0036] With this configuration, the glass guide rail assembly has a lower guide rail 2 and an upper guide rail 3. The lower guide rail 2 is inserted into the mounting groove 11, a part of the upper guide rail 3 is located in the mounting groove 11 of the lower guide rail 1, and the other part of the upper guide rail 3 is used to install in the decorative panel 6. This allows the upper guide rail 3 and the lower guide rail 2 to be assembled separately, reducing the difficulty of assembly and the assembly time. At the same time, by setting the limiting structure 4 to restrict the relative position of the lower guide rail 1 and the lower guide rail 2, it is possible to prevent the lower guide rail 2, which is pre-installed on the lower guide rail 1, from sliding along the length direction in the mounting groove 11, thus avoiding sealing failure or abnormal noise caused by guide rail displacement.
[0037] Alternatively, please refer to Figure 2 and Figure 3 The upper guide rail 3 and the lower guide rail 2 are spaced apart along the length of the lower guide rail 1, and the distance between the end of the upper guide rail 3 located in the mounting groove 11 and the end of the lower guide rail 2 near the upper guide rail 3 is 8mm-12mm.
[0038] With this arrangement, the upper guide rail 3 and the lower guide rail 2 are arranged in a series at intervals along the length of the lower guide rail 1, providing redundant space for the assembly of the upper guide rail 3 and the lower guide rail 2, facilitating their assembly. At the same time, space is reserved for thermal expansion, avoiding dynamic interference between the upper guide rail 3 and the lower guide rail 2 when the glass 7 is raised or lowered.
[0039] Preferably, the distance between the end of the upper guide rail 3 located in the mounting groove 11 and the end of the lower guide rail 2 near the upper guide rail 3 is 10mm.
[0040] Alternatively, please refer to Figure 4 The two edges of the mounting groove 11 are bent inward to form two retaining edges 12. The lower guide rail 2 has two limiting parts 22. Both limiting parts 22 are fixedly connected to the outer wall of the guide groove 21. The two limiting parts 22 are correspondingly engaged between the two retaining edges 12 and the groove wall of the mounting groove 11.
[0041] With this design, the hook-shaped structure formed by the inward bending of the retaining edge 12 can effectively lock the limiting part 22 of the lower guide rail 2, preventing the guide rail from coming out or warping in the direction perpendicular to the length of the mounting groove 11, and maintaining stability, especially when the glass 7 is subjected to lateral force during lifting and lowering; at the same time, the locking relationship between the limiting part 22 and the retaining edge 12 provides an initial installation positioning point for the lower guide rail 2, ensuring that the guide rail is in a precise position when inserted into the mounting groove 11, reducing subsequent adjustment processes and improving assembly efficiency.
[0042] Further, please refer to Figure 6 At least one of the two limiting parts 22 is provided with a limiting groove 42, and the lower guide rail 1 is fixedly connected with a limiting block 41 corresponding to the limiting groove 42, and the limiting block 41 is disposed in the limiting groove 42.
[0043] With this configuration, the plastic can be directly injection molded into structures such as the retaining edge 12 and the limiting block 41, avoiding secondary machining or riveting of the metal and reducing the number of parts. The cooperation between the limiting block 41 and the limiting groove 42 prevents the lower guide rail 2, which is pre-installed on the lower guide rail 1, from sliding along the length direction in the mounting groove 11, thus avoiding sealing failure or abnormal noise caused by guide rail displacement.
[0044] Preferably, the lower guide rail 1 is made of plastic material.
[0045] It is understood that the limiting block 41 can be set on the end face of the lower guide rail 1 away from the upper guide rail 3, or it can be set at any position of the lower guide rail 1 corresponding to the lower guide rail 2. Those skilled in the art can adapt the setting position of the limiting block 41 according to the actual situation. This embodiment and the accompanying drawings are only one illustration.
[0046] Alternatively, please refer to Figure 5 The upper guide rail 3 includes a body 31 and a lip 32. A part of the body 31 is inserted into the mounting groove 11, and the other part of the body 31 is used to install in the trim panel 6. The lip 32 is fixedly connected to the body 31, and the lip 32 is used to abut against the glass slider 5. Specifically, the lip 32 and the body 31 are integrally formed.
[0047] This configuration creates a dynamic seal through the lip 32, and the upper guide rail 3 maintains continuous contact with the glass slider 5 through elastic deformation, preventing wind and rain from seeping in, while also reducing frictional noise during the lifting and lowering of the glass 7.
[0048] Secondly, this embodiment provides a car door, which includes a trim panel 6, a glass slider 5, a glass 7, and the aforementioned glass guide rail assembly. A portion of the upper guide rail 3 is installed in the trim panel 6, one end of the glass slider 5 is slidably connected to the glass guide rail assembly along the length direction of the lower guide rail 1, and the other end of the glass slider 5 is fixedly connected to the glass 7.
[0049] With this design, the door uses segmented upper guide rail 3 and lower guide rail 2, which facilitates assembly and reduces assembly time. At the same time, when the lip 32 is worn, only the corresponding upper guide rail 3 needs to be replaced, without disassembling the lower guide rail 1, which facilitates door maintenance.
[0050] Thirdly, a vehicle is provided, the vehicle including the aforementioned door.
[0051] Example 2:
[0052] Please refer to Figure 7This embodiment has a structure that is largely the same as that of Embodiment 1, except that at least one of the two limiting parts 22 is provided with a limiting groove 42. Along the length direction of the lower guide rail 1, a limiting block 41 corresponding to the limiting groove 42 is detachably connected to the end of the lower guide rail 1 away from the upper guide rail 3, and the limiting block 41 is disposed in the limiting groove 42. Specifically, the lower guide rail 1 is made of metal material.
[0053] With this setup, there is no need to re-mold the lower guide rail 1 made of metal material. By using the detachable limiting block 41 and the limiting groove 42 to cooperate, the lower guide rail 2 can be limited, preventing the lower guide rail 2, which is pre-installed on the lower guide rail 1, from sliding along the length direction in the mounting groove 11, thus avoiding sealing failure or abnormal noise caused by guide rail displacement.
[0054] Specifically, the limiting block 41 includes a buckle nested in the outer wall of the lower guide rail 2, and a protrusion on the end face of the buckle away from the upper guide rail 3. The protrusion is located in the limiting groove 42 to limit the relative position of the lower guide rail 2 and the lower guide rail 1.
[0055] 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 various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments 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.
