A rotary sealing structure for drive motors of new energy vehicles

Abstract

The invention relates to the technical field of motor sealing for new energy vehicles, specifically a rotary sealing structure for driving motors of new energy vehicles, including a motor, a driving mechanism, a heat dissipation mechanism, a pressure relief mechanism, an air injection mechanism, a sealing mechanism and a clamping mechanism ;The installation of the heat dissipation mechanism is conducive to the discharge of the heat when the motor is working, and it also prevents the heat from entering the inner side of the motor and causing damage to the circuit. Driven by the mechanism, the gas injection mechanism moves to generate gas, so as to expand and seal the sealing mechanism, which is conducive to sealing the external circuit and the motor, preventing rainwater and dust from entering, causing circuit damage, and under the action of the pressure relief mechanism. It is beneficial to discharge excess gas inside the sealing mechanism and prevent damage to the sealing mechanism. At the same time, the installation of the clamping mechanism facilitates the clamping and storage of redundant circuits and the convenience of taking them out.

AI Technical Summary

Problems solved by technology

[0003] Electric drive is the most common in the manufacturing process of new energy vehicles. It is through the connection between the battery and the motor, so that the motor rotates and works to generate power for the car. However, when the car is used in an outdoor environment, it will inevitably be exposed to a large amount of dust and rain. However, the connection between the motor and the external circuit is usually directly sealed by a rubber ring, which will deform and loosen after a long time, causing rainwater and dust to enter the inside of the motor and damage the circuit
