[0002] With the support of the state for new energy vehicles and the strict restrictions on fuel vehicles, the number of new energy vehicles in use is increasing, and the number of electric vehicles with battery swapping is also increasing at the present stage.

[0003] The current difficulties in promoting battery swapping battery packs are as follows: 1) Professional battery swapping stations are required; 2) Large sites are needed; 3) High-power electrical configurations are required; these factors affect the promotion of battery swapping vehicles, and it is necessary to further explore a more suitable battery swapping solution for new energy heavy truck scenarios.

[0004] At the same time, the existing technical problems are as follows: Since the battery swapping vehicle is a heavy truck with a large body, when charging at a general charging site, the charging port on the battery pack may not be able to align with the charging gun position of the charging pile at the charging site. Due to the insufficient length of the charging cable, the vehicle cannot be charged. The charging port of the bracket assembly is arranged on the surface closest to the charging pile to facilitate gun insertion for charging. When a heavy truck electric vehicle needs battery swapping, a forklift removes the depleted battery pack from the vehicle to be swapped and places it in the waiting area. Then, it takes a fully charged battery pack from the bracket station, transfers it to the vehicle to be swapped, places the depleted battery pack in the waiting area on the bracket assembly, and inserts the charging gun of the charging pile to complete the charging. Summary of the Invention

[0005] Technical Solution: To solve the above technical problems, the utility model provides a fixed bracket station device for a battery pack of a heavy truck for battery swapping, which specifically includes an upper battery pack mounting, a vehicle-mounted base, a bracket assembly, and a charging pile at the charging site; the bottom of the bracket assembly is fixedly installed on a horizontal plane, and the top surface is connected to the upper battery pack mounting; the vehicle-mounted base is installed at the four end points on the top of the bracket assembly to strengthen the connection between the upper battery pack mounting and the bracket assembly; the bracket assembly is installed in the charging station to facilitate docking with the charging pile at the charging site, and the charging pile at the charging site is installed near the bracket assembly.

[0006] As an improvement, it further includes a charging port of the bracket assembly, which is fixedly installed on the side of the bracket assembly and is connected to the charging gun of the charging pile at the charging site.

[0007] As an improvement, it further includes a connector for the upper battery pack mounting and a connector for the vehicle-mounted base; the connector for the upper battery pack mounting is electrically connected to the connector for the vehicle-mounted base in an insertion-fitting manner; the connector for the vehicle-mounted base is electrically connected to the charging port of the bracket assembly in an insertion-fitting manner.

[0008] As an improvement, the upper-mounted connector of the battery pack is fixedly installed at the bottom of the upper-mounted part of the battery pack, and the vehicle-mounted base connector is fixedly installed on the top end surface of the bracket assembly.

[0009] Advantages: Compared with the existing conventional devices, the device proposed by the present invention solves the current technical problems. Specifically, this device has a simple design, is functional, easy to produce, and convenient to operate. It can be arranged near the charging pile in the charging place to realize on-site battery replacement. The battery replenishment cycle is convenient and efficient, thus providing many conveniences for users. Description of the Drawings
