Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, and particularly relates to a PDU control module for a new energy vehicle. Background Technique

[0002] The PDU plays a core role in power distribution and management in new energy vehicles. It is responsible for effectively distributing electrical energy to various high-voltage components, such as motors, air conditioners, battery management systems, etc., to ensure the normal operation of the vehicle. The PDU control module has multiple functions, mainly including charge and discharge control, power-on control of high-voltage components, circuit overload and short-circuit protection, high-voltage sampling, and low-voltage control. Through these functions, the PDU can achieve precise management of the vehicle's high-voltage power distribution, ensure the stable supply of electrical energy, and prevent safety problems caused by circuit failures.

[0003] Currently, the sealing covers of most PDU control modules are fixed by screws. When components such as fuses inside the PUD control module are damaged, the sealing cover needs to be opened for repair. Since the screws need to be removed one by one, it takes a relatively long time, reducing the repair efficiency of the PDU control module. Content of the Utility Model

Four fixed racks are meshed with the outer surface of the driving gear. Four fixing grooves are opened on the inner surface of the support ring. One end of each of the four fixed racks is inserted into the corresponding fixing groove.

[0006] As a further preferred embodiment of this technical solution, a rotating shaft is fixedly connected to the top end of the driving gear.
