[0002] With the transformation of the global energy structure and the increasing awareness of environmental protection, the market demand for electric vehicles, as a green alternative to traditional fuel vehicles, has shown an explosive growth trend. The popularization of electric vehicles can not only effectively alleviate the pressure of global oil resource depletion, but also significantly reduce exhaust emissions, combat air pollution and climate change. In this context, the construction and development of charging / swapping stations as key infrastructure supporting the daily operation of electric vehicles is particularly important. With the continuous advancement of electric vehicle technology, especially the continuous improvement of the host power of the charging stack, higher requirements are also placed on the performance and safety of supporting equipment. Among them, the PCU (Power Control Unit) power distribution unit, as one of the core components of the charging stack, is responsible for efficiently and safely distributing electrical energy to each charging module. Its importance is self-evident. However, with the increase in power level, the volume and weight of the PCU power distribution unit have also increased significantly, bringing great challenges to the installation of the production line.

[0003] Traditionally, production lines rely mainly on manual handling when installing PCU power distribution units. This method is not only inefficient and labor-intensive, but also poses serious safety hazards. Since the weight and volume of the PCU power distribution unit far exceed the comfortable range of manual handling, operators are prone to fatigue and mistakes during handling, and even serious accidents such as heavy objects falling and injuring people may occur. In addition, charging piles of different models and power levels have different requirements for the size and installation location of the PCU power distribution unit. Traditional installation methods are difficult to meet such diverse needs. Summary of the invention

[0007] The lifting assembly is a scissor-type lifting mechanism.

[0008] The pushing device connected to the lifting assembly is a height-adjusting electric push rod, and the execution end of the height-adjusting electric push rod is connected to the vertex hinge of the parallelogram at the lowest end of the scissor-type lifting mechanism.

[0010] The fork arm adjustment rod assembly includes two adjustment rods connected in an X structure, the intersection of which is connected by a pin shaft, and the intersection is connected to a fork arm adjustment electric push rod.

[0011] The bottom of the base assembly is provided with a corner wheel for pushing the lifting mechanism to move to the installation location of the PCU power distribution unit; the base assembly is provided with a handle.

[0012] An electrical control box is also provided on the base assembly, and the electrical control box is connected to the pushing device.

[0013] The driving mechanism is a pneumatic actuator, a hydraulic actuator or an electric actuator.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention discloses a lifting mechanism for installing a PCU power distribution unit of a charging pile. A fixed plate and a slide rail assembly are arranged on the lifting assembly for placing the PCU power distribution unit. The lifting assembly can adjust the height of the lifting mechanism to meet the different installation heights of the PCU power distribution unit of the charging pile.
