Abstract

The present invention proposes a protective structure for a drive motor of a new energy passenger car, which includes a bottom plate, the bottom plate is provided with a protective cover for enclosing the side of the motor, the upper surface of the bottom plate is provided with a bracket, and the bracket is fixed with a rotating shaft, so The rotation of the rotating shaft is provided with two oppositely arranged rotating arms for fixing the driving motor. The rotating shaft sleeve is provided with two torsion springs with opposite torque directions and corresponding to the rotating arms one by one. One spring foot of the torsion spring It is connected with the rotating arm, and the other spring foot is connected with the rotating shaft. The output shaft of the driving motor is provided with a first output gear, and the rotating shaft is provided with a second output gear meshed with the first output gear to solve the circumferential vibration of the motor. technical problems.

Description

technical field [0001] The invention relates to a protective structure for a drive motor of a new energy passenger car. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. The motor is represented by the letter M (the old standard is D) in the circuit, and its speed can change with the input voltage and current, and it can be used as a power source for electrical appliances or various machinery. Because the motor speed is variable, the moment of inertia changes when the rotor speed changes, so its vibration is mainly the circumferential vibration generated when the rotor speed changes. [0003] In the prior art, an invention patent titled "a protective device for high-power variable-frequency motors" with an authorized announcement number of CN108599434B and an authorized announcement date of 2020.04.07 was disclosed, including the main body of the motor protective...
