[0002] The widespread adoption and rapid development of electric vehicles have placed higher demands on charging infrastructure. As a crucial infrastructure for replenishing electric vehicle energy, the performance and reliability of electric vehicle charging stations are paramount. However, existing electric vehicle charging station power socket designs have several shortcomings, limiting improvements in charging efficiency and user experience. First, existing power sockets often have limited configurations for their outgoing and incoming cable ports, failing to meet the diverse connection requirements of different electric vehicles and charging needs. Furthermore, the installation and removal of power sockets are cumbersome, hindering rapid deployment and maintenance. Second, existing power sockets pose safety hazards in terms of electrical connections. Additionally, existing power sockets lack scalability and modular design. Utility Model Content
[0003] In view of this, the purpose of this utility model is to provide a modular, highly reliable, easy-to-maintain and expandable power supply base for electric vehicle charging stations.
[0004] To achieve the above objectives, this utility model employs a power supply base for an electric vehicle charging station, comprising a power supply base with a lower mounting plate. One end of the power supply base is movably connected to a first outgoing terminal block, which has at least one set of outgoing ports. One side of the power supply base is movably connected to a first incoming terminal block, which has at least one set of incoming ports corresponding to the outgoing ports. An outgoing connection plate is provided between the lower mounting plate and the power supply base. An upper mounting plate is provided on top of the lower mounting plate. An incoming connection plate is provided between the lower mounting plate and the upper mounting plate. A plug-in shell is integrally formed on one side of the upper mounting plate. A control board is inserted into the plug-in shell. The control board extends outward through a plug-in slot in the plug-in shell and has a power plug-in port. A plug-in cover is provided on top of the plug-in shell.
[0005] The advantages of the above structure are as follows: the modular design of the power socket, including the lower mounting plate, upper mounting plate, outgoing connection plate, and incoming connection plate, allows each part to be replaced or upgraded independently, improving the maintainability and expandability of the power socket. The movable connection design between the first outgoing terminal block and the first incoming terminal block and the power socket allows the terminal block to be flexibly adjusted or replaced according to actual needs, adapting to different electric vehicles and charging requirements.
[0006] This utility model further configures each group of outgoing ports to include one positive output port and one negative output port, and each group of incoming ports to include a corresponding positive input port and a negative input port. By setting positive and negative ports for the outgoing and incoming ports respectively, the correct transmission and reception of electrical energy is ensured. This design not only simplifies the power transmission process but also improves the accuracy and security of transmission. Even with multiple groups of incoming ports, it can effectively avoid power transmission errors or malfunctions caused by port mismatch.
[0007] This utility model further comprises a second outgoing terminal block integrally formed at one end of the power socket, corresponding to the first outgoing terminal block, and a second incoming terminal block integrally formed on the other side of the power socket, corresponding to the first incoming terminal block. The outgoing connection plate is electrically connected to the power socket and extends to both the first and second outgoing terminal blocks. The incoming connection plate is electrically connected to the lower mounting plate and extends to both the first and second incoming terminal blocks. Outgoing terminal covers and incoming terminal covers are respectively provided on the first and second outgoing terminal blocks and the first and second incoming terminal blocks. The design of the outgoing and incoming connection plates ensures stable power transmission from the power grid to the power socket and then to the electric vehicle, improving charging efficiency and reducing power loss and failure rates during transmission. The terminal covers protect the terminals from external environmental interference, thereby improving the safety and reliability of the power socket.
[0008] This utility model is further configured such that the outgoing connection plate is provided with a riveted copper post, the riveted copper post containing a copper post crown spring, the lower mounting plate has a corresponding sleeve at the position of the riveted copper post on the corresponding outgoing connection plate, and the incoming connection plate has a sleeve mounting groove at the position of the corresponding sleeve for clamping the outer wall of the sleeve, and an integrally formed conductive post is provided on one side of the sleeve mounting groove, the conductive post containing a conductive post crown spring. By installing copper post crown springs and conductive post crown springs inside the riveted copper post and the conductive post, the tightness and stability of the electrical connection are significantly improved, reducing electrical faults caused by poor contact or loosening, thereby ensuring the continuity and stability of current transmission.
[0009] This utility model is further configured such that the upper mounting plate has an opening slot for the extension portion of the corresponding sleeve, and the upper mounting plate also has an insulating boss at the position of the conductive post corresponding to the inlet connection plate. By providing the opening slot, the sleeve and its extension portion can be flexibly arranged and adjusted on the upper mounting plate, adapting to different installation environments and requirements, thus improving its installation flexibility and adaptability. The insulating boss provides electrical isolation, effectively preventing accidental electrical connections between the conductive post and the upper mounting plate, helping to reduce the risk of electrical faults and short circuits, thereby ensuring the safety and reliability of the circuit.
[0010] This utility model further features a riveting hole on the outgoing connection plate at the corresponding position of the riveted copper post. The riveted copper post is fixed in the riveting hole by riveting and extends between the outgoing connection plate and the power base. The riveting method securely fixes the riveted copper post between the outgoing connection plate and the power base. This connection method is more stable and reliable than traditional welding or bolting connections, effectively resisting vibration and impact, and ensuring the stability and safety of current transmission.
[0011] This utility model further features a first wiring screw on the inlet connection plate at the corresponding positions of the first and second inlet terminal blocks. The inlet connection plate has a first guide slope that contacts the first inlet terminal block. The bottom of the inlet connection plate maintains planar contact with the second inlet terminal block and the lower mounting plate. The use of the first wiring screws simplifies and stabilizes the connection between the inlet connection plate and the first and second inlet terminal blocks. The first guide slope on the inlet connection plate guides the connection, making it easier for the first inlet terminal block to align and contact with the inlet connection plate, reducing alignment difficulty during installation and improving installation accuracy and efficiency. The planar contact between the bottom of the inlet connection plate and the second inlet terminal block and the lower mounting plate not only enhances the stability of the connection but also improves heat dissipation.
[0012] This utility model further features a second wiring screw on the outgoing connection plate at the corresponding positions of the first and second outgoing terminal blocks. The outgoing connection plate has a second guide slope that contacts the first outgoing terminal block. The bottom of the outgoing connection plate maintains planar contact with the second outgoing terminal block and the power supply base. The second wiring screws simplify and streamline the connection between the outgoing connection plate and the first and second outgoing terminal blocks. The second guide slope on the outgoing connection plate guides and aligns the components, ensuring accurate alignment when the first outgoing terminal block contacts the outgoing connection plate, reducing installation errors and difficulties. The planar contact between the bottom of the outgoing connection plate and the second outgoing terminal block and the power supply base not only facilitates heat conduction and dissipation, improving heat dissipation performance, but also enhances electrical conductivity.
[0013] This utility model further features a splicing slot on one end of the power socket corresponding to the second outgoing terminal and one side of the second incoming terminal. The splicing slot is used for splicing with other power sockets. The control board has at least one power socket plug-in port for each power socket connected via splicing, for gas connection. The plug-in cover has port slots corresponding to the power socket plug-in ports and the power socket plug-in ports themselves. The plug-in cover also has a connector, which houses a connector that plugs into the control board. By providing the splicing slots, the power sockets can be spliced together, flexibly expanding the number and functionality of the power sockets according to actual needs. The power socket plug-in ports on the control board ensure normal power transmission between the spliced power sockets.
[0014] This utility model is further configured such that the upper mounting plate, the lower mounting plate, and the power supply base are connected by a first mounting screw; the first and second outgoing terminal blocks are both movably connected to the outgoing terminal cover by a first snap-fit; the first outgoing terminal block is movably connected to the power supply base by a second snap-fit; the first and second incoming terminal blocks are both connected to the incoming terminal cover by a second mounting screw; and the first incoming terminal block is connected to the power supply base by a third snap-fit. By using the first mounting screw to connect the upper mounting plate, the lower mounting plate, and the power supply base, the stability and reliability of the entire structure are ensured. The design of the first and second snap-fits makes the connection between the outgoing terminal block and the power supply base more flexible and convenient. The use of the second mounting screw ensures that the electrical connection between the incoming terminal block and the incoming terminal cover is stable and reliable. The third snap-fit connection between the first incoming terminal block and the power supply base ensures the tightness and stability of the electrical connection. Attached Figure Description
