Description

Technical Field

[0001] The utility model relates to the technical field of gaskets, in particular to a positioning gasket. Background Art

[0002] The car window regulator is composed of a window regulator motor and an electronic module. It can be divided into left front door, left rear door, right front door, and right rear door window regulators according to the different installation positions. The electronic module of the window regulator can control the motor to rotate forward or reverse, thereby effectively controlling the rising or falling process of the car window. The car window regulator system is mainly composed of windows, window regulators, motors, relays, switches, ECUs and other devices. Among them, the glass regulator system is the main component of the electric window, which relies on the motor to drive the glass regulator to automatically rise or fall. Figure 1 and Figure 2 As shown, the auxiliary gasket 1' is installed on the top of the armature shaft 3' of the window motor 2'. At the same time, the auxiliary gasket 1' is also constrained by the copper sleeve 4'. During actual use, the motor will generate heat when it rotates. Gaskets made of general materials are not wear-resistant and high-temperature resistant, and are easily worn. After wear, the motor will have abnormal noise and stall probability. PEEK is a high-heat special engineering plastic. PEEK has excellent physical properties such as high strength, high temperature resistance, corrosion resistance, radiation resistance, flame retardancy, fatigue resistance, self-lubrication and low noise. The existing PEEK gasket needs to be embedded in the copper sleeve at the top of the armature shaft. The outer wall of the gasket has a large contact surface with the inner wall of the copper sleeve. Therefore, it is difficult to install and the assembly process is time-consuming and laborious. Utility Model Content

[0003] The utility model aims to provide a positioning gasket to solve at least one of the above problems existing in the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A positioning gasket comprises a gasket body, wherein the gasket body is made of PEEK material, a plurality of vertical ribs are arranged on the outer periphery of the gasket body, and recessed areas are formed between adjacent vertical ribs.

[0006] In the present technical solution, since a plurality of vertical ribs are provided on the outer periphery of the gasket body and recessed areas are formed between adjacent vertical ribs, during installation, the contact area between the gasket body and the copper sleeve is reduced, and the recessed areas do not contact the inner wall of the copper sleeve. Therefore, even when the outer diameter of the gasket body is slightly larger than the inner diameter of the copper sleeve, the gasket body can be easily pressed into the copper sleeve and made to abut against the end of the armature shaft. The present technical solution solves the problem of time-consuming and labor-intensive matching installation between the gasket and the copper sleeve in the prior art.

[0007] Furthermore, in order to facilitate molding and ensure the overall uniformity of the structure, the length of the vertical ribs is consistent with the thickness of the gasket body.

[0008] Furthermore, in order to reduce the contact area with the inner wall of the copper sleeve as much as possible, the free end of the vertical rib in a top view has a pointed portion.

[0009] Furthermore, a vertical rib that is easy to form is provided as an example, and the cross section of the vertical rib is a triangle.

[0010] Furthermore, if the diameter of the gasket is large during processing, it is difficult to ensure the flatness of the forming. Therefore, in order to ensure the flatness of the middle part that abuts the armature shaft as much as possible, the thickness of the middle part of the gasket body is greater than the thickness of the edge, and the middle part of the gasket body forms a middle thickened plane.

[0011] Furthermore, in order to facilitate installation, the middle parts of the two end surfaces of the gasket body are provided with a middle thickened plane.

[0012] The beneficial effects of the utility model are as follows: in this technical solution, since a plurality of vertical ribs are provided on the outer periphery of the gasket body and recessed areas are formed between adjacent vertical ribs, during installation, the contact area between the gasket body and the copper sleeve is reduced, and the recessed area does not contact the inner wall of the copper sleeve. Therefore, even when the outer diameter of the gasket body is slightly larger than the inner diameter of the copper sleeve, the gasket body can be conveniently pressed into the copper sleeve and made to abut against the end of the armature shaft. This technical solution solves the problem of time-consuming and labor-intensive matching installation between the gasket and the copper sleeve in the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0021] Embodiment 1:

[0022] like Figure 3-Figure 4 As shown, this embodiment provides a positioning gasket, including a gasket body 1. The gasket body 1 is made of PEEK material. A plurality of vertical ribs 2 are provided on the outer periphery of the gasket body 1, and recessed areas 3 are formed between adjacent vertical ribs 2.

[0023] In the present technical solution, since a plurality of vertical ribs 2 are provided on the outer periphery of the gasket body 1 and recessed areas 3 are formed between adjacent vertical ribs 2, during installation, the contact surface between the gasket body 1 and the copper sleeve is reduced, and the recessed area 3 does not contact the inner wall of the copper sleeve. Therefore, even when the outer diameter of the gasket body 1 is slightly larger than the inner diameter of the copper sleeve, the gasket body 1 can be easily pressed into the copper sleeve and made to abut against the end of the armature shaft. The present technical solution solves the problem of time-consuming and labor-intensive matching installation between the gasket and the copper sleeve in the prior art.

[0034] This embodiment is optimized based on the above-mentioned embodiment 1.

[0035] If the diameter of the gasket is large during processing, it is difficult to ensure the flatness of the forming. Therefore, in order to ensure the flatness of the middle part that abuts the armature shaft as much as possible, the thickness of the middle part of the gasket body 1 is greater than the thickness of the edge, and the middle part of the gasket body 1 forms a middle thickened plane 5.

[0036] Embodiment 6:
