Description

Technical Field

[0001] This utility model belongs to the field of charging terminal structure design technology, and relates to the internal structure of a charging terminal. Background Technology

[0002] With the development of electric vehicles, charging piles have experienced explosive growth, and various regions are encouraging and supporting their construction and installation to meet the charging needs of electric vehicles. The charging speed, appearance design, component layout, footprint, price, and ease of use of a charging pile directly affect its market share. The rational layout of the internal components of a charging terminal not only affects charging efficiency but also directly impacts its heat dissipation performance, ease of maintenance, and long-term operational stability. Considering the scarcity of land resources, the miniaturization and modular design of charging terminals to reduce footprint and improve space utilization has become an important direction for industry development. Price, as a crucial factor in consumer decision-making, drives charging terminal manufacturers to continuously explore the balance between cost control and technological innovation to provide products with higher cost-effectiveness. Furthermore, ease of use, such as broad compatibility, is also an indispensable element in enhancing the market competitiveness of charging terminals.

[0003] The internal components of existing charging terminals are relatively scattered, and there are many components used, resulting in high cost of charging terminals. They are also inconvenient for customers to connect wires and have poor heat dissipation performance. Utility Model Content

[0004] The purpose of this invention is to solve the technical problems of the relatively dispersed internal component layout and the large number of components used in the existing charging terminal, which leads to high charging cabinet costs and poor heat dissipation performance, and to provide an internal structure for the charging terminal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, the present invention provides an internal structure of a charging terminal, including a charging terminal housing, the charging terminal housing comprising a left compartment and a right compartment with a reserved cable passage in the middle; the left compartment is provided with a cooling system, and the right compartment is provided with other components of the charging terminal besides the cooling system; the other components include, in the right compartment, arranged sequentially from top to bottom, an auxiliary power supply, a TMU control board, a SECC, a low-voltage terminal block unit, a charging gun terminal block, a charging gun wire, a shunt, a fuse, a DC contactor, and a DC conductor assembly; the cooling pipes of the cooling system cool the charging gun wire through the cable passage;

[0007] The right compartment is equipped with a gun address dial switch, a liquid-cooled control board, a first DC surge protector, an incoming line terminal block, and a network cable terminal block on its side wall.

[0008] The right compartment is equipped with a right compartment door, and inside the right compartment door are a switch, a TCU control board, a 10-inch interactive screen, and a card reader.

[0009] Further improvements are made in the following aspects:

[0010] The low-voltage terminal block unit includes a circuit breaker, an AC surge protector, a low-voltage terminal block, and a DC meter, all mounted on standard electrical rails.

[0011] An indicator light panel is also provided on the inside of the right compartment door; a fan is provided on the inside of the right compartment door at a position directly in front of the DC conductor assembly.

[0012] The gun wire terminal block and charging gun wire are located in the middle of the right compartment; an inspection light is installed on the top of the right compartment.

[0013] An emergency stop switch and a second DC surge protector are also installed on the side of the right compartment.

[0014] The top of the right compartment is equipped with a right compartment access control switch connected to the TCU control board, which is used to realize the power-off function when the door is opened.

[0015] The top of the left compartment is equipped with a left compartment access control switch connected to the TCU control board, which is used to realize the power-off function when the door is opened.

[0016] The power input method of the charging terminal is positive, negative + PE input.

[0017] An insulation detector is also installed in the right compartment at the same position as the SECC.

[0018] Each component in the TMU control board, insulation tester, SECC, and low-voltage terminal block unit is protected by a transparent PC board.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model discloses an internal structure of a charging terminal, dividing the terminal body into a left compartment and a right compartment. The left compartment houses only the cooling system, while all other components are rationally arranged in the right compartment. On one hand, without affecting the charging terminal's performance, this rational arrangement reduces the number of components, optimizes the structural design, and lowers the cost of the charging terminal. On the other hand, the compartmentalized arrangement distributes the charged components and electrical elements in different areas, facilitating wiring for customers and resulting in an aesthetically pleasing and heat-dissipating layout. This component layout satisfies user convenience, improves assembly efficiency, and enhances the user experience. Furthermore, the overall appearance features a lower left compartment and a higher, narrower right compartment, resulting in a neat and aesthetically pleasing overall design.

[0021] Furthermore, a fan is installed on the inner side of the right compartment door, directly in front of the DC conductor assembly, and the fan is located on the lower side of the right compartment door to meet the heat dissipation requirements of the charging terminal.

[0022] Furthermore, the gun wire terminal block and charging gun wire are located in the middle of the right compartment, which satisfies the position of the gun wire and allows for a more reasonable connection with the DC conductor assembly.

[0023] Furthermore, the power input method of the charging terminal is positive, negative + PE input. The DC input is transmitted through a cable, output from the PCU power distribution unit of the DC charging host, and then connected to the conductor assembly of the charging terminal along the cable. The conductor assembly of the charging terminal is located in the lower part of the cabinet. By optimizing the conductor length, layout space is saved, the space utilization of the conductor assembly is improved, and sufficient height is reserved for DC input wiring, which facilitates on-site construction and wiring.
