[0025] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.
[0026] As used herein, the term "including" and its variations mean open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "based at least in part on". The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment".

[0027] Figure 1 FIG. 1 shows an installation structure diagram of a lifter glass bracket structure on a vehicle door according to an embodiment of the present invention. Figure 1 As shown, the lifter glass bracket structure includes a glass bracket 1 and a lifter guide rail 3. The lifter guide rail 3 is installed on the vehicle door, the glass bracket 1 cooperates with the lifter guide rail 3, the vehicle door glass 2 is installed on the glass bracket 1, and the glass bracket 1 slides up and down along the lifter guide rail 3, thereby driving the vehicle door glass 2 to be lifted or lowered.
[0028] Figure 5 A schematic diagram showing the structure of a slider according to an embodiment of the present invention is shown. Figure 6 A schematic diagram showing a lifter glass bracket structure according to an embodiment of the present invention is shown, Figure 7 Shows Figure 6 The cross-sectional view of AA in Figure 5 , 6 As shown in Figures 7 and 8, the glass holder 1 cooperates with the lifter guide rail 3, and the glass holder 1 can slide up and down along the lifter guide rail 3. The lifter guide rail 3 has two guide rail pieces 31 arranged in a mirror image, and a guide groove 32 is formed between the two guide rail pieces, and the guide rail piece 31 is L-shaped. The glass holder 1 includes a glass holder body and a slider 13. An intermediate support body is formed in the middle of the back of the glass holder body, and an L-shaped slide groove 111 is formed on both sides of the intermediate support body. The slider 13 is fixedly arranged in the L-shaped slide groove 111. The intermediate support body is arranged in the guide groove 32, and the slider 13 wraps the guide rail piece 31. In the process of the glass holder 1 sliding along the lifter guide rail 3, only the slider 13 is in contact with the lifter guide rail 3. Preferably, the curved arm of the L-shaped guide rail piece 31 extends outward.
[0029] It can be understood that the lifter guide rail 3 uses two L-shaped guide rail pieces 31, and the slider 13 on the glass bracket 1 wraps the two L-shaped guide rail pieces 31, so that the glass bracket 1 cannot be displaced in the left and right, front and back and rotational directions relative to the lifter guide rail 3, and only the freedom of up and down displacement is left, which improves the stability of the glass when the door glass is closed, reduces the shaking of the lifter bracket, and thus can reduce noise.
[0030] Furthermore, the slider is made of polyoxymethylene-POM material, which has excellent mechanical properties, high strength and rigidity, good elasticity, good wear resistance, low friction coefficient and good self-lubricating property. The slider made of POM can greatly reduce the noise generated by the friction between the glass bracket 1 and the guide rail 31, and further reduce noise.
[0031] Furthermore, a wrapping cavity for wrapping the guide rail piece is formed on the slider 13. Obviously, the wrapping cavity is also L-shaped. A plurality of protrusions 131 are formed on the inner wall of the wrapping cavity. When the glass holder 1 slides along the lifter guide rail 3, only the protrusions 131 are in sliding contact with the guide rail piece 31. It should be noted that the number and position of the protrusions 131 should ensure the stability of the cooperation between the glass holder 1 and the lifter guide rail 3, which is sufficient to limit the shaking of the lifter holder 1. The use of the protrusions 131 in cooperation with the guide rail piece 31 reduces the contact area between the slider 13 and the guide rail piece 31, thereby further reducing noise.
[0032] In some embodiments, the protrusions 131 are arranged in pairs, and each pair of protrusions 131 is located at relative positions on both sides of the guide rail piece 31. This ensures the stability of the glass holder 1 and the lifter guide rail 3. The middle part of the intermediate support body has an opening, and a support arm 112 is formed on both sides of the opening, and the L-shaped slide groove 111 is located on the outside of the support arm 131. The intermediate support body is separated from the middle to form two support arms 112, so that the inner side of the L-shaped slide groove 111 has a certain elasticity, making it easier to assemble the glass holder 1 and the lifter guide rail 3.
[0033] Figure 2 A schematic structural diagram of a glass bracket according to an embodiment of the present invention is shown. Figure 3 A schematic diagram showing the structure of a hard rubber bracket according to an embodiment of the present invention is shown. Figure 4 A schematic diagram of the structure of a soft rubber bracket according to an embodiment of the present invention is shown. Figure 2 , 3 As shown in , 4, the main body of the glass bracket includes a hard rubber bracket 11 and a soft rubber bracket 12, the soft rubber bracket 12 is fixed inside the hard rubber bracket 11, and the slider 13 is fixed on the hard rubber bracket 11. The hard rubber bracket 11 is provided with a bracket, and the soft rubber bracket is fixed in the bracket. A glass clamping structure is formed on the soft rubber bracket, and the door glass 2 is connected to the glass bracket 1 through the glass clamping structure, and the door glass 2 does not contact the hard rubber bracket 11. By dividing the main body of the glass bracket into an external hard frame and an internal soft bracket structure, the strength of the glass bracket 1 is guaranteed, and the door glass 2 can reduce the noise generated by the vibration of the glass under the support of the soft rubber bracket 12, and further reduce the noise generated during the lifting of the door glass.
[0034] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive. The structures and connection modes of the components in the present invention can be changed, and any equivalent transformations and improvements based on the technical solution of the present invention should not be excluded from the protection scope of the present invention.
