[0051] See also Figures 8 and 9 , Figure 8 yes Figure 6 The exploded structural diagram of the guide rail assembly 100 is shown in FIG. Figure 9 yes Figure 6 A schematic structural diagram of the guide rail assembly 100 (without fixing parts) is shown.

[0052] The injection molded part 30 is fixedly connected between the guide rail body 12 and the bracket 20. Specifically, the injection molded part 30 covers the fixing portion 21 and is fixedly connected between the guide rail body 12 and the fixing portion 21 to install the bracket 20 on the guide rail body 12. The injection molded part 30 is fixedly connected between the first surface 122 and the third surface 212. In this embodiment, the injection molded part 30 is made of hard plastic, and its Rockwell hardness is greater than or equal to 70 and less than or equal to 100, so as to ensure the strength of the injection molded part 30 and prevent the injection molded part 30 from being deformed. Exemplarily, the hard plastic can be a composite material including polypropylene plastic (PP) and 30% glass fiber (GF), a composite material including nylon 66 plastic (PA66, Polyadiohexylenediamine) and 30% glass fiber, and acrylonitrile butadiene styrene plastic (ABS, Acrylonitrile Butadiene Styrene plastic).

[0053] In addition, the injection molded part 30 is provided with a fourth fixing hole 301.

In some embodiments, there may be one or more than three fourth fixing holes 301, which is not a limitation of this disclosure.

[0054] In this embodiment, the molded part 30 is formed using an injection molding process. Specifically, the bracket 20 and the guide rail body 12 are connected together using the injection molding process. During the process of forming the molded part 30 using the injection mold, the bracket 20 is positioned relative to the reference surface 222 of the assembly portion 22, and the guide rail 10 is positioned relative to the guide rail body 12. The molded part 30 is then formed using the injection molding process.

[0055] It should be noted that the injection molded part 30 formed by the injection molding process can absorb the manufacturing tolerances of the first surface 122 of the guide rail body 12 and the third surface 212 of the fixing part 21. During the assembly of the bracket 20 and the guide rail 10, the assembly between the bracket 20 and the guide rail body 12 through the injection molded part 30 will not affect the cantilever part 11, and there will be no risk of out-of-tolerance in the assembly between the cantilever part 11 and the first window glass 200 and the second window glass. The assembly accuracy of the guide rail 10 and the window can be guaranteed, and the overall assembly stability of the vehicle 10000 can be guaranteed.

For example, the first fixing member 40 can be a structural member such as a screw or bolt that can perform a fixing function.

[0057] When the second window glass is raised or lowered relative to the guide rail 10 , or when the vehicle 10000 vibrates during driving, the first fixing member 40 can ensure the connection strength between the bracket 20 and the guide rail body 12 , thereby improving the assembly stability between the bracket 20 and the guide rail body 12 .

[0058] In this embodiment, the guide rail 10 and the bracket 20 are assembled using an injection molded part 30. The injection molded part 30 can absorb the manufacturing tolerances of the first surface 122 of the guide rail body 12 and the third surface 212 of the fixing part 21, thereby reducing the impact of the manufacturing tolerances of the guide rail body 12 and the fixing part 21 on the cantilever part 11, improving the product qualification rate, and also improving the assembly stability of the cantilever part 11 and the first window glass 200 and the second window glass, thereby improving the overall assembly stability of the vehicle 10000 and the reliability of the use of the vehicle 10000.
