Compared with traditional fuel vehicles, electric vehicles lack the masking of engine noise during driving, making wind noise, road noise, and powertrain noise more prominent. An acoustic package is an important component in a vehicle for reducing noise, and it reduces the transmission of noise through mechanisms such as sound absorption, isolation, and reflection.

[0003] The existing use environment of automotive motors is relatively harsh, and the fixing effect of the existing acoustic coating fixing device is average. Chinese Patent CN220562525U discloses a fixing device for an acoustic coating of a motor, including a fixing plate and a boss. The motor body is fixed inside the boss. An installation hole is opened at the top of the fixing plate. The top of the boss penetrates through the installation hole and extends above the fixing plate. A clamping component is embedded in the inner wall of the installation hole for fixing the boss. Sound insulation sleeves are fixedly provided on both the inner wall and the outer wall of the boss. In the utility model, the electric push rod drives the clamping block to be clamped with the clamping groove on the boss. By means of the electric push rod driving the clamping block to automatically clamp, manual operation is not required, and it is very time-saving and labor-saving to use. At the same time, six screws are used to fix the fixing plate to the vehicle, which is convenient for installing and disassembling the fixing plate and the boss. Sound insulation sleeves are provided on both the inner wall and the outer wall of the boss to reduce the transmission of noise. At the same time, a heat conducting block can conduct the heat of the motor body to the heat dissipation fins, and a heat dissipation fan is used to blow air to accelerate the heat dissipation effect of the heat dissipation fins.

[0004] However, this patent still has the following problems: During the installation process, it is necessary to align the clamping groove and the clamping block before clamping, the operation is complex, and the error during the installation process will directly damage the device structure, resulting in low installation efficiency.
