Description

Technical Field

[0001] The utility model relates to the technical field of motor controllers, in particular to an integrated motor controller component for an electric vehicle. Background Art

[0002] The existing electric vehicle motor controller integrated components are composed of various internal electronic components. However, when they are used, they do not have shock absorbers. Electric vehicles will be subjected to vibrations from the road and the body during driving, and these vibrations will be directly transmitted to the motor controller. Over a long period of time, continuous vibration may cause the circuit components inside the motor controller to loosen or be damaged, affecting its normal operation. If the electric vehicle experiences a large impact, such as passing through a bumpy road or encountering a collision, the motor controller without a shock absorber will be more susceptible to the impact, which may cause a circuit short circuit, component damage or failure, and thus cause the motor controller to fail to work properly. Secondly, there is no heat dissipation device. After the equipment is used for a long time in a high temperature environment, a large amount of heat will be generated. If the motor controller integrated component does not have a heat dissipation device, the circuit components may be damaged or malfunction due to excessive temperature, which will also cause the electric vehicle control system to fail and fail to operate normally.
