Description

Technical Field

[0001] The utility model relates to the technical field of glass lifters, in particular to a rotating wheel assembly structure of a glass lifter. Background Art

[0002] In recent years, with the increasing popularity of new energy vehicles at home and abroad, the lightweight of the whole vehicle has been paid more and more attention by various OEMs. The integrated door template integrates the glass lifter guide rail, speaker mounting structure, interior mounting structure and the door template into an integral injection molding. Due to its good assemblability and significant lightweight performance, more and more OEMs choose the integrated door template in the lifting system; due to the influence of the layout, when the glass lifter guide rail overlaps with the speaker mounting structure, the traditional wheel assembly structure is to connect the wheel to the speaker mounting structure through a pin and two gaskets. This assembly structure has the following two shortcomings, such as Figure 1 As shown:

[0003] a. In order to assemble the pin 2 and reserve space for the gasket, the speaker fitting surface 3 needs to be partially reduced in material design (i.e. Figure 1 The arc-shaped groove at the lower left of the middle pin shaft 2) causes the size of the speaker's fitting surface 3 to become smaller, resulting in poor sealing and the risk of water leakage;

[0004] b. In order to assemble the rotating wheel, it is necessary to rivet the pin 2 for connection and also to assemble two gaskets, which makes the assembly process complicated. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a rotary wheel assembly structure for a glass lifter, which solves the problems of easy water leakage and inconvenient assembly caused by unreasonable rotary wheel assembly structure in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A rotating wheel assembly structure of a glass lifter, comprising:

[0008] A mounting column, which is fixed on the speaker mounting structure, wherein the outer diameter of the mounting column matches the inner diameter of the rotating wheel;

[0009] a fastener, threadedly connected to the mounting post;

[0010] A gasket is located between the fastener and the mounting column and is sleeved outside the fastener. The outer diameter of the gasket is greater than the inner diameter of the rotating wheel.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] On the one hand, the assembly structure only requires the installation of gaskets and fasteners (such as Figure 2 As shown in the figure), it replaces the method in the prior art that requires riveting the pin shaft on the speaker mounting structure and assembling the gasket on both sides, avoiding the partial reduction of the speaker bonding surface, ensuring the integrity of the bonding surface and the waterproof effect (as shown in the figure). Figure 3 shown);

[0013] On the other hand, the fastener is threadedly connected to the mounting column and only needs to be assembled with one gasket, which ensures assembly reliability while simplifying the assembly steps, achieving quick assembly and easy disassembly.

[0014] Furthermore, a cylinder is fixedly provided on the top end of the mounting column, a convex block is fixedly provided on the inner ring of the gasket, and a free end of the convex block is interference-fitted with an outer wall of the cylinder.

[0015] Furthermore, the protrusion extends downward.

[0016] Furthermore, an annular groove is provided at the top end of the mounting column, and the free end of the protrusion extends into the groove.

[0017] Furthermore, at least two protrusions are provided and are distributed on the annular side of the cylinder.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments; the structures described in the various embodiments can be freely combined without any conflict in structure or principle.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "inner", "outer", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0036] The utility model proposes a wheel assembly structure of a glass lifter, comprising a mounting column 4, a fastener 5 and a gasket 6, wherein:

[0037] like Figure 2 and Figure 4 As shown, the mounting column 4 is fixedly arranged on the front side of the existing speaker mounting structure 1 (i.e., the side away from the speaker fitting surface 3), and the outer diameter of the mounting column 4 matches the inner diameter of the rotating wheel 7. Specifically, as shown in FIG. Figure 4As shown, the runner 7 itself has a sink and a through hole coaxially arranged from top to bottom, wherein the diameter of the through hole is smaller than the diameter of the sink. When installed, the through hole of the runner 7 passes through the outer wall of the mounting column 4, and the through hole of the runner 7 is coaxial with the outer diameter of the mounting column 4 and has clearance fit;

[0038] The fastener 5 is coaxially arranged with the mounting column 4, and the mounting column 4 has a cylindrical cavity so that the fastener 5 can be connected thereto by threads; the gasket 6 is arranged between the fastener 5 and the top of the mounting column 4, and the gasket 6 is sleeved outside the fastener 5; in order to limit the upward movement of the rotating wheel 7 during operation, the outer diameter of the gasket 6 is set to be larger than the inner diameter of the rotating wheel 7 (that is, the through-hole diameter of the rotating wheel 7); the gasket 6 is pressed between the fastener 5 and the mounting column 4 by the fastener 5, so that, in the axial direction, the upper and lower end faces of the rotating wheel 7 are respectively limited by the gasket 6 and the front face of the speaker mounting structure 1, and in the radial direction, the mounting column 4 limits excessive shaking of the rotating wheel 7, and the assembly is stable.

[0039] By adopting the above scheme, on the one hand, the present assembly structure only needs to install the gasket 6 and the fastener 5 on the front side of the speaker mounting structure 1, replacing the prior art method of riveting the pin 2 on the speaker mounting structure 1 and installing the gasket 6 on both sides, thus avoiding the partial reduction design with the speaker fitting surface 3 (i.e. Figure 1 On the other hand, the fastener 5 is threadedly connected to the mounting column 4 and only needs to be assembled with a gasket 6, which ensures the reliability of the assembly while simplifying the assembly steps, achieving quick assembly and easy disassembly.

[0040] Furthermore, the mounting column 4 and the speaker mounting structure 1 are integrally injection molded. Exemplarily, the mounting column 4 is molded using an existing slider core-pulling structure; thus, the mounting column 4 is easy to manufacture and has a low cost.

[0041] Furthermore, the fastener 5 includes a self-tapping screw. By screwing the self-tapping screw into the cavity of the mounting column 4, the inner wall of the cavity can be processed into an internal thread matching the self-tapping screw. There is no need to pre-process the internal thread in the cavity, which facilitates assembly and reduces costs.

[0042] In another embodiment of the present invention, the outer wall of the cylinder 401 is provided with an external thread, and the fastener 5 includes a nut. The fastener 5 is sleeved on the outer wall of the cylinder 401 and is threadedly connected to the cylinder 401 (not shown in the figure); in this way, the fastener 5 and the mounting column 4 can be quickly disassembled and assembled, and the manufacturing is simple and low-cost.

[0043] In another embodiment of the present invention, based on the above embodiment, in order to prevent the fastener 5 from loosening during operation, the gasket 6 is set to be interference fit with the mounting column 4; specifically, Figure 2 , Figure 4 and Figure 5 As shown, a cylinder 401 is fixedly provided on the top of the mounting column 4. Exemplarily, the cylinder 401 and the mounting column 4 are integrally injection molded, and a protrusion 601 is fixedly provided on the inner ring of the gasket 6. The free end of the protrusion 601 extends toward the cylinder 401 and abuts against the outer wall of the cylinder 401 to achieve an interference fit between the two. Of course, in order to ensure that the gasket 6 is not easy to rotate, the protrusion 601 can be set to at least two, for example but not limited to, the protrusion 601 is set to six, and the six protrusions 601 are evenly distributed in a ring shape on the inner ring of the gasket 6. In this way, the gasket 6 is easy to disassemble and assemble, and has sufficient friction with the cylinder 401, to ensure that the gasket 6 and the fastener 5 will not rotate during operation.

[0044] In another embodiment of the present invention, based on the above embodiment, Figure 2 and Figure 3 As shown, each protrusion 601 extends downward (i.e., away from the direction of the screw head); in this way, when the gasket 6 is inserted downward into the cylinder 401, the protrusion 601 is slightly deformed by the upward reaction force, which can increase the interference fit between the protrusion 601 and the cylinder 401, thereby ensuring the stability and convenience of the gasket 6 assembly.

[0045] Furthermore, the gasket 6 can be made of hard materials such as rubber, resin or solid metal. For example, Figure 4 As shown, the gasket 6 and the protrusion 601 are both made of metal to ensure the rigidity of the gasket 6 and enhance the effect of limiting the upward movement of the rotating wheel 7; when the rigidity of the gasket 6 is relatively large, an annular groove is provided at the top of the mounting column 4, and the free end of the protrusion 601 extends into the groove to avoid movement interference with the fastener 5 during the downward screwing process. In addition, during assembly, the protrusion 601 is first pressed into the groove to position the gasket 6; the specific installation process is as follows: first, the rotating wheel 7 is put on the outside of the mounting column 4, and then the protrusion 601 is pressed into the groove, and finally the self-tapping screw is tightened, which is convenient to assemble and reliable to lock.
