[0033] At present, new energy vehicles are generally equipped with DC charging sockets to complete the charging process by connecting with charging guns. However, unfortunately, the existing DC charging socket panel designs on the market are quite monotonous and lack of interactivity. During charging, users cannot directly obtain any real-time information about the charging status from the appearance surface of the socket, which undoubtedly brings inconvenience to the charging experience of users and fails to fully meet the needs of users for convenience.

[0034] In order to overcome the above technical problems, with reference to Figures 1-7 The embodiment provides a DC charging socket, which comprises:

[0035] A flange piece 1 comprising a flange panel 11 and a flange back cover 12, the flange back cover 12 being installed on the back side of the flange panel 11, and a first installation cavity being formed between the flange back cover 12 and the flange panel 11;

[0036] A lamp panel installed in the first installation cavity, the lamp panel being provided with a light emitter, and the light emitter being exposed through the flange panel 11;

[0037] A back shell 2 installed on the back side of the flange piece 1, and a second installation cavity being formed in the inside of the back shell 2;

[0038] An electric transmission assembly 3 installed in the second installation cavity, and used for realizing external charging by connecting with an external charger.

[0039] The flange piece 1 is a support basic structure of the entire DC charging socket, the flange piece 1 is composed of the flange panel 11 and the flange back cover 12, the flange back cover 12 is installed on the back side of the flange panel 11, and a closed first installation cavity is formed between the flange back cover 12 and the flange panel 11, which not only provides space for the installation of the lamp panel, but also ensures the protection of the lamp panel and the internal components thereof and prevents the interference of the external environment.

[0040] The light-emitting bodies are arranged on the lamp panel and exposed through the openings or transparent parts on the flange panel 11, so that the user can directly observe the state of the light-emitting bodies from the outside. The design of the lamp panel not only increases the interactivity of the socket, but also provides the user with intuitive charging status information. In specific implementation, the lamp panel is connected with the charging control system or sensor signal of the vehicle, so that the control system of the vehicle can control the display state of the light-emitting bodies on the lamp panel, thereby realizing the function of displaying related charging prompt information.

[0041] The rear shell 2 is mounted on the back side of the flange 1 and forms a second mounting cavity inside, which is used to mount the electric transmission assembly 3 responsible for interfacing with the external charger to realize the function of external charging. The design of the rear shell 2 not only ensures the safety and stability of the electric transmission assembly 3, but also makes the structure of the entire socket more compact and beautiful.

[0042] The direct current charging socket provided by the embodiment has the beneficial effect that by arranging the first mounting cavity on the flange 1 and installing the lamp panel, the light-emitting bodies can be exposed and display information related to the charging state. In this way, the user can directly obtain real-time information of the charging state from the appearance of the socket without the need to check other devices or indicator lights, thereby greatly improving the charging experience of the user. In the specific structure, the lamp panel and the electric devices such as the electric transmission assembly 3 are respectively installed in the first mounting cavity and the second mounting cavity, which realizes effective protection of the electric devices, which is conducive to guaranteeing the reliability of the entire charging socket and improving the compactness and stability of the structure of the charging socket.

[0043] In an embodiment, the flange panel 11 is provided with a lamp hole corresponding to each light-emitting body, and the light-emitting body is exposed through the lamp hole.

[0044] This embodiment realizes the visualization and intuitive improvement of the charging state, enhances the interactivity, reduces the cost, improves the reliability and aesthetics, and provides the user with a more friendly and convenient use experience by arranging the lamp hole corresponding to the light-emitting body on the flange panel 11.

[0045] In an embodiment, referring to Figure 2 , the light-emitting body includes any one or more of the illumination lamp 41, the state indicator lamp 43, and the power indicator lamp 42.

[0046] The illumination lamp 41 can provide additional illumination function to facilitate the user to perform charging operation in the dark or insufficient light environment. The state indicator lamp 43 can display the working state of the charging socket, such as charging, charging completion, fault, etc., to help the user quickly understand the current charging state. The power indicator lamp 42 can display the remaining power of the battery or charging device, and the user can determine when to end the charging according to the display of the power indicator lamp 42 to avoid overcharging or undercharging.

[0047] This embodiment can provide users with more comprehensive and detailed charging status information by combining different functional light-emitting bodies, thereby enhancing the user's charging experience.

[0048] In an embodiment, the lamp panel is further provided with a control key 44, and the flange panel 11 is provided with a key hole corresponding to the control key 44, and the control key 44 is exposed through the key hole.

[0049] The control key 44 can have multiple functions according to actual needs, such as starting / stopping charging, adjusting charging mode (such as fast charging / slow charging), viewing charging history, etc., which provides users with more choices and flexibility. Alternatively, the control key 44 can also be used to control the switch of the illuminating lamp 41, so that the illuminating lamp 41 can be turned off at hand after the user completes the charging plug-in, reducing power loss.

[0050] The number, position and function of the control key 44 can be customized according to the actual needs of users to better adapt to different use scenarios and user needs.

[0051] In an embodiment, referring to Figure 4 , the flange panel 11 includes a panel body 111 and a support edge 112 connected to the side of the panel body 111 and protruding backward, and the support edge 112 is adapted to be mounted on a mounting body; a mounting recess 1113 is formed between the support edge 122 and the panel body 111, and the flange rear cover 12 is mounted in the mounting recess 1113.

[0052] Specifically, the mounting body is generally a structure on the vehicle for mounting the charging socket. The side of the panel body 111 is provided with the support edge 112 protruding backward, so that the support edge 112 can be fitted to the support body, that is, the panel body 111 serves as the main mounting support body and needs to bear a large force and pressure, so a material structure with sufficient strength needs to be selected. The flange rear cover 12 mainly plays a closing and protecting role, and the strength of the material and structure is relatively low. By mounting the flange rear cover 12 in the mounting recess 1113 between the support edge 112 and the panel body 111, a material with lower cost can be selected to manufacture the flange rear cover 12, thereby reducing the overall cost.

[0053] The design of the mounting recess 1113 makes the installation of the flange rear cover 12 more simple and convenient, and the installer only needs to insert the flange rear cover 12 into the mounting recess 1113 and fix it properly.

[0054] In an embodiment, the flange rear cover 12 has an avoiding through hole 121 formed in the middle, and the rear shell 2 is connected and locked with the flange panel 11 through the avoiding through hole 121.

[0055] In this embodiment, an avoiding through hole 121 is designed in the middle of the flange rear cover 12, and the rear shell 2 is connected and locked with the flange panel 11 through the avoiding through hole 121. This embodiment not only improves the compactness and installation convenience of the product, but also enhances the stability of the connection and reduces the cost.

[0056] In the structure of the flange panel 11, a plug-in hole 1111 is also provided to allow the charging gun to be inserted, and the electrical transmission assembly 3 inside the rear shell 2 is aligned with the plug-in hole 1111 to realize the docking function of the charging gun and the electrical transmission assembly 3.

[0057] In one embodiment, a pluggable sealing plug 5 is installed on the flange 1, which can be inserted into the plug-in hole 1111 after charging to achieve waterproofing.

[0058] In one embodiment, the rear shell 2 is provided with a connecting hole, and the back side of the flange panel 11 is provided with a threaded hole 1112 corresponding to the connecting hole. The connecting screw 24 passes through the connecting hole and is screwed into the threaded hole 1112 to lock the rear shell 2 to the flange panel 11.

[0059] By providing a connecting hole on the rear shell 2 and a threaded hole 1112 corresponding to the connecting hole on the back side of the flange panel 11, and then using a connecting screw 24 for threaded connection, the firm connection between the rear shell 2 and the flange panel 11 can be ensured. This connection method has high tensile strength and shear strength, can withstand large external forces and vibrations, and ensures the stability and reliability of the connection. In addition, the connection method using the connecting screw 24 is relatively simple, and the installer only needs to pass the connecting screw 24 through the connecting hole and screw it into the threaded hole 1112. This installation method does not require complex tools or equipment, reducing the installation difficulty and cost. If the rear shell 2 needs to be disassembled for maintenance or replacement, the connecting screw 24 only needs to be loosened. This design makes maintenance work simpler and more convenient, reducing maintenance cost and time.

[0060] In one embodiment, the flange rear cover 12 is provided with a pressing edge 122 near the edge of the avoiding through hole, which is pressed between the rear shell 2 and the flange panel 11 to fix the flange rear cover 12.

[0061] The design of the pressing edge 122 enables the flange rear cover 12 to be effectively pressed between the rear shell 2 and the flange panel 11 during assembly. This pressing action not only increases the contact area between the flange rear cover 12 and the rear shell 2 and the flange panel 11, but also improves the tightness and stability of the connection, thereby enhancing the overall fixing effect.

[0062] In an embodiment, the bottom side of the rear shell 2 is provided with a lower wire outlet hole 22, and the external power line 7 can extend to the inside of the second mounting cavity through the lower wire outlet hole 22 to be connected with the electric transmission assembly 3.

[0063] In an embodiment, one end of the external power line 7 is connected with the electric transmission assembly 3, and the other end is connected with the charging control system inside the vehicle, so as to realize charging of the vehicle battery through the power line 7.

[0064] The rear shell 2 is provided with a lower wire outlet hole 22 at the bottom side, and the vertical wire outlet can significantly reduce the occupied space of the tail part. This design makes the charging device more compact in layout, which is beneficial to save space and improve space utilization. The vertical wire outlet can avoid the bending of the power line 7, and is also convenient for fixing and protecting the power line 7, further improving the safety.

[0065] In an embodiment, the back side of the rear shell 2 is provided with a tail mounting hole 21, and the tail cover plate 23 is mounted at the tail mounting hole 21. The electric transmission assembly 3 inside can be accessed through the tail mounting hole 21.

[0066] The tail mounting hole 21 is arranged at the back side of the rear shell 2, which is convenient for wiring or disconnection of the internal power line 7 and the electric transmission assembly 3. In addition, when the electric transmission assembly 3 needs to be maintained, checked or replaced, only the tail cover plate 23 needs to be opened, without the need to disassemble the entire rear shell 2 or other parts. This design simplifies the maintenance process and reduces the maintenance cost. The existence of the tail cover plate 23 can ensure the neatness and integrity of the appearance of the device when the electric transmission assembly 3 does not need to be accessed, and can prevent harmful substances such as dust and moisture from entering the inside of the device, protecting the electric transmission assembly 3 from damage.

[0067] In an embodiment, an electronic lock 6 is further arranged in the direct current charging socket. After the charging gun is connected with the charging socket, the electronic lock 6 can lock the charging gun, preventing unrelated personnel from pulling out the charging gun at will and causing interruption of charging.
