[0002] With the continuous development of the electric vehicle industry under the background of new energy, the construction of charging pile stations has also entered a period of rapid development. Traditional charging piles are fixed installations, with one charging spot corresponding to one charging pile. The charging spots cannot be shared, and the charging piles are idle most of the time, resulting in a waste of resources.
[0003] Existing technologies have proposed a mobile charging pile that can move between various charging stations to connect the charging station and the vehicle to be charged. However, in the above technologies, the power supply wiring of the charging equipment is usually connected by a plug-in connection. Plug-in connections require high precision, resulting in a complex connection structure, high cost, and susceptibility to deviations. There is room for improvement. Therefore, a charging pile wiring mechanism is proposed to solve the above problems. Utility Model Content

[0008] The connection box is equipped with multiple sets of retractable terminals, each terminal having a retaining spring that pushes the terminal to maintain continuous contact with the corresponding docking seat. The connection box also contains a power supply unit, which is electrically connected to the terminal to supply power to the charging pile.
[0009] Furthermore, the connecting box is provided with a sealing cover and a driving unit;
[0010] The connecting box has an opening on the side facing the docking seat, and the closing cover is slidably disposed in the opening;

[0012] Furthermore, the charging base is provided with a rainproof eave on top, which is located above the docking seat.
[0013] Furthermore, the connection box is equipped with a controller, which is used to activate the drive unit to open the sealing cover when the connection box on the charging pile moves to below the rainproof eaves.
[0014] Furthermore, the drive unit includes a drive unit electrically connected to the controller;
[0015] The output end of the drive unit is provided with a transmission gear;
[0016] The end of the closed cover near the drive unit is provided with a driven gear plate that meshes with the transmission gear.
[0017] Furthermore, the end of the terminal block is provided with anti-slip texture, and the end of the terminal block is made of conductive metal.
[0018] Furthermore, a mobile trolley is provided at the bottom of the charging pile, which is used to carry the charging pile and move it along the guide rail to the designated charging position.
[0019] The beneficial effects of this utility model are reflected in:
[0020] In this utility model, during use, as the charging pile moves toward the charging base, the connection box on the charging pile connects with the docking seat on the charging base. The terminal head is located inside the connection box and is retractable. It can be continuously connected to the docking seat under the resistance of the spring to achieve power connection. The above method replaces the traditional plug-in power supply structure, requires low connection accuracy, and has low cost, which is conducive to promotion and use. Attached Figure Description

Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0031] Please see Figure 1-4 This utility model discloses a charging pile wiring mechanism for connecting the charging pile 1 and the charging base 2, comprising:
[0032] A connection box 11 is disposed on the charging pile 1;
[0033] The docking seat 22 is provided in multiple sets and is disposed on the charging seat 2.
[0034] The connection box 11 is provided with multiple sets of retractable terminal blocks 12. Each terminal block 12 is provided with a contact spring 13, which is used to push the terminal block 12 to continuously contact the corresponding docking seat 22.

[0035] When this application is in use, as the charging pile 1 moves toward the charging base 2, the connection box 11 set on the charging pile 1 docks with the docking seat 22 set on the charging base 2, and the terminal head 12 is set inside the connection box 11. The terminal head 12 is retractable and can be continuously connected to the docking seat 22 under the abutment of the abutment spring 13 to realize power connection.
