[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort in accordance with the embodiments of the basic utility model are within the protection scope of this utility model.
[0016] like Figure 1-3 As shown in the figure, a flange 1 is included, which is fixedly connected to the main body 3 by screws. The main body 3 is connected to the main body rear cover 4. A guide structure is also provided on the flange 1 on both sides of the main body 3. This guide structure is a guide sleeve 2 fixed on the flange 1. With the setting of the guide sleeve 2, during charging, the guide shaft of the plug cooperates with the guide sleeve to achieve precise positioning of the plug and the socket.
[0017] A funnel-shaped structure is provided at the entrance of guide sleeve 2. The charging base guide structure adopts a funnel structure, thereby achieving guidance and positioning over a larger size range, reducing the accuracy requirements for automatic charging plug recognition, and enabling the car to automatically find charging devices through automatic parking accuracy to meet the automatic charging positioning requirements, thus achieving the popularization of automatic charging at a lower cost. The funnel structure of this charging base guide structure enables the miniaturization and weight reduction of the charging plug and the charging base structure, which is more conducive to the matching design of the charging base with the vehicle body structure.
[0018] like Figure 7 As shown, the charging dock adopts a guiding structure with two guide sleeves 2, which can achieve better matching of plug and socket and avoid the problem of wear on one side after repeated plugging and unplugging.
[0019] like Figure 4-7 As shown, the main body 3 is equipped with positive and negative power terminals 13 and signal terminals 7. The signal terminals 7 are fixed and limited by the signal terminal bracket 8. The PCB board 9 is fixedly connected to the inside of the main body 3 by screws. The low-voltage plug 5 is connected to the outside of the main body rear cover 4. The signal terminals 7 are connected to the PCB board 9 and integrated into the low-voltage plug 5 to achieve modular assembly. The terminal inner bracket 11 is fixedly connected inside the main body rear cover 4. The main body rear cover 4 is also equipped with an aluminum busbar 10. The power terminals 13 and the aluminum busbar 10 are fixedly connected by bolts and are insulated and isolated by the terminal inner bracket 11. A thermally conductive silicone block 14 is attached to the power terminals 13. A temperature sensor 15 is attached to the thermally conductive silicone block 14 and integrated into the end of the low-voltage plug 5 through the PCB board 9, which can better monitor the heating and temperature rise of the power terminals.
[0020] The aluminum strip 10 is equipped with a rear cover 12, such as Figure 8As shown, the back cover 12 consists of two semi-male and female connecting blocks, which are assembled by snap-fit. This makes it easy for the positive and negative aluminum busbars to be assembled independently into the charging base. If it were designed as a single unit, the back cover and sealing ring must be assembled together before the aluminum busbars are installed, which would make the assembly of the aluminum busbars with their complex bending structure extremely difficult.
[0021] The guide sleeve 2 and the flange 1 are fixedly connected by press-fitting, and are connected to the slot by snap ring 16 to prevent them from falling off after long-term use.
[0022] A sealing ring is provided between the main body 3 and the main body back cover 4, between the signal terminal 7 and the main body 3, and between the aluminum busbar 10 and the main body back cover 4. The sealing is achieved through the connection of the sealing ring, which is dustproof and waterproof.
[0023] For better fixation, flange 1, body 3 and body rear cover 4 are fixed together by screws.
[0024] The main body rear cover 4 is also connected to a grounding copper busbar 6, which is connected to the grounding terminal 17 on the flange 1.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
