[0002] The generator is usually ventilated and cooled by air inlet at the vent hole of the rear end protection cover, the protection cover with the vent hole directly opened on the plane of the protection cover cannot effectively guide the air inlet, so that the motor cannot be effectively cooled, and the plane vent hole cannot effectively block the mud and oil flowing from the obliquely upper direction of the motor installation direction, so that the mud and oil enter the motor, corroding the internal parts of the motor.

[0003] The generator is usually connected with the vehicle wire harness through screws, when the installation space of the generator is wide, the axial connection screw can meet the installation requirement, but when the installation space of the generator is small, the generator usually uses the side-out screw to connect with the vehicle wire harness, in this case, the axial connection screw is inconvenient or even interferes with the connection.

[0004] The brush on the generator usually uses the protection structure of the plastic brush cap, but when the generator encounters the harsh environment with much dust and mud and oil, the protection structure of the plastic brush cap cannot effectively prevent the dust and mud and oil from entering, and in the worst case, the brush is stuck, and the motor fails to generate electricity.

[0005] When the front end cover of the generator encounters a large load impact or a harsh application environment with large vibration intensity, cracks may occur, and in severe cases, the bearing may even break and be damaged. SUMMARY
