Description

Technical Field

[0001] The utility model belongs to the technical field of motor sealing, and in particular relates to a sealing ring used for sealing a resolver wiring harness of a two-in-one driving motor. Background Art

[0002] As the market demand for new energy electric vehicles continues to increase, end customers are also increasingly demanding the reliability and stability of electric vehicle components. This requires that the structural design of the motor should be convenient, fast, simple, and reliable to improve product competitiveness.

[0003] At present, on the two-in-one drive motor, the resolver wiring harness is installed on the rear cover, and then the resolver cover plate is sealed by gluing. At present, this method has the following problems: 1. The output wires of the resolver stator are wire-row type, and are in a scattered state when passing through the end cover wire slot. Therefore, the resolver wires are easy to fall out of the wire slot and are pressed on the closing surface when the box is closed, resulting in damage to the wiring harness and insulation failure, leading to resolver failure; 2. If the sealing method at the wire slot position is to use glue, the amount of glue is difficult to control and the sealing performance at this position is poor; 3. The resolver cover plate is complicated to disassemble and assemble by gluing, and it is difficult to repair. Utility Model Content

[0004] In view of the above problems in the prior art, the utility model aims to provide a sealing ring for sealing a two-in-one drive motor resolver wiring harness, which solves the problem that the prior art uses a gluing method to seal the resolver wiring harness, which easily leads to wiring harness damage and failure.

[0005] In order to achieve the above utility model purpose, the technical solution adopted by the utility model is as follows:

[0007] Furthermore, the upper and lower end surfaces of the annular sealing ring body are both provided with a circle of mounting grooves, which are convenient for cooperating with the limiting protrusions in the rear end cover of the two-in-one driving motor to realize the positioning of the entire sealing ring.

[0008] Furthermore, as a specific setting mode of the protective cover, the protective cover is in a rectangular parallelepiped structure, and a plurality of the harness through holes extend from the front of the protective cover to the back of the protective cover. Specifically, when the sealing ring is used to seal the resolver harness, a fixing groove can be set in the rear end cover of the two-in-one drive motor, and the protective cover can be installed and fixed by installing the protective cover in the fixing groove. The resolver harness can pass through the harness through hole on the protective cover, and the sealing ring and the protective cover are compacted to achieve the sealing of the resolver harness.

[0009] Furthermore, each of the wiring harness through holes is a necked hole.

[0010] Furthermore, a plurality of mounting protrusions are arranged at intervals on the outer side wall and the inner side wall of the annular sealing ring body. The arrangement of the mounting protrusions facilitates more firmly fixing the entire sealing ring.

[0011] Furthermore, the plurality of harness through holes are parallel to each other and arranged horizontally, and the length directions of the harness through holes are all oriented toward the center direction of the annular sealing ring body.

[0012] Furthermore, the material of the protective sleeve is silicone; the material of the annular sealing ring body is rubber.

[0013] Furthermore, the annular sealing ring body includes a circular ring body, the bottom of the circular ring body is protruding downward to provide a connecting section, the protective sleeve is arranged on the connecting section, and two limiting ears are symmetrically protruding outward on both sides of the top of the circular ring body, and each of the limiting ears is in a circular ring structure; the protective sleeve, the circular ring body, the connecting section and the two limiting ears are an integrated structure.

[0014] The beneficial effects of the utility model are as follows: the utility model is a sealing ring for sealing the resolver wiring harness of a two-in-one drive motor, a protective cover is added to the annular sealing ring body, a harness through hole is set on the protective cover, and the resolver wiring harness passes through the harness through hole, so that before installing and pressing the resolver cover plate, the resolver wiring harness can move relative to the protective cover, and the harness through hole is a necking hole, so as to achieve the sealing effect after pressing the resolver wiring harness. After the entire sealing ring is installed, the position of the protective cover is stuck in the fixed groove in the rear end cover of the two-in-one drive motor to fix the position of the resolver wiring harness, and the limit protection and sealing functions are achieved at the same time after the box surface is pressed. The setting of the sealing ring optimizes the spatial position of the resolver wiring harness, fixes the resolver wiring harness in the protective cover, fixes the position of the resolver wiring harness, eliminates the risk of pressure loss of the resolver wiring harness after assembly, and the design of the necking hole ensures the sealing, thereby improving the reliability and stability of the product; the sealing ring replaces the method of gluing to achieve the sealing of the resolver wiring harness, and the disassembly and assembly are simple and easy to repair.
