Description

Technical Field

[0001] This utility model relates to the field of electric vehicle charging technology, and in particular to a heat dissipation structure for an electric vehicle charging socket. Background Technology

[0002] With the increasing popularity of electric vehicles, the performance and reliability of charging equipment have become a focus of attention. When a charging gun is plugged into a charging socket, it generates a significant amount of heat during the charging process. Poor heat dissipation can lead to overheating, affecting charging efficiency and safety.

[0003] In existing technologies, the heat dissipation structure of charging gun sockets mostly involves direct contact with the terminals inside the socket, conducting heat to the outside of the socket. However, the material of the heat dissipation structure is a major challenge. Metal heat dissipation structures lack sufficient insulation, while plastic heat dissipation structures do not meet the required thermal conductivity. Therefore, there is an urgent need for a heat dissipation solution that combines high thermal conductivity with good insulation. Utility Model Content

[0004] In order to simultaneously improve the thermal conductivity and insulation of the heat dissipation structure, this application provides a heat dissipation structure for an electric vehicle charging socket.

[0005] The heat dissipation structure for an electric vehicle charging socket provided in this application adopts the following technical solution: A heat dissipation structure for an electric vehicle charging socket includes a housing and a heat sink. The heat sink is disposed within the housing and has a first assembly hole through which the inner terminal of the charging gun socket passes. A plurality of heat sink fins are disposed on the outer side wall surface of the heat sink. The housing has a plurality of heat dissipation grooves through which the heat sink fins pass. The heat sink fins extend out of the heat dissipation grooves to the outside of the housing. Both the heat sink and the heat sink fins are made of ceramic material.

[0006] By adopting the above technical solution, the socket terminals pass through the outer shell. The heat sink is made of ceramic, which significantly improves the thermal conductivity compared to ordinary plastic parts. The heat sink is a ceramic structure and is radially distributed on the heat sink. The heat sink extends from inside the outer shell to outside the outer shell. Together with the heat sink, it conducts the heat generated during the use of the terminals to the outside of the outer shell. Both the heat sink and the heat sink have a certain thickness, and the length directions of each heat sink are parallel to each other. With the help of a gas delivery device such as an air pump or fan installed in the socket, the airflow of the gas delivery device blows parallel to the length direction of the heat sink to improve the heat dissipation performance. At the same time, the ceramic used to make the heat sink and heat sink is an insulating material, which improves the insulation performance of the heat dissipation structure and reduces safety risks.

[0007] Preferably, an assembly adhesive is provided between the inner wall of the first assembly hole and the terminal, and the assembly adhesive is made of a silicone-based high thermal conductivity adhesive material.

[0008] By adopting the above technical solution, the assembly adhesive improves the stability of the connection between the heat sink and the terminal, thereby improving the stability of the overall structural assembly. The assembly adhesive is made of silicone-based high thermal conductivity adhesive material, which has good thermal conductivity, thereby improving the thermal conduction efficiency and further improving the thermal conductivity performance.

[0009] Preferably, the heat sink is embedded in the outer casing.

[0010] By adopting the above technical solution, injection molding facilitates production, improves the stability of the connection between the heat sink and the outer casing, and enhances structural strength and sealing performance.

[0011] Preferably, the housing is provided with an opening slot for the terminal to pass through, the housing is provided with an assembly sleeve for closing the opening slot, and the assembly sleeve is provided with a second assembly hole for the terminal to pass through.

[0012] By adopting the above technical solution, the assembly of the sealed outer shell opening groove is improved, thereby reducing the probability of foreign objects entering and damaging the internal structure.

[0013] Preferably, the assembly sleeve is slidably fitted onto the outer shell, the assembly sleeve is provided with an installation groove, and the outer shell is provided with an installation block that is inserted into the installation groove.

[0014] By adopting the above technical solution, the mounting block is inserted into the mounting slot, thereby assembling the assembly sleeve onto the outer shell, which facilitates the assembly of the outer shell and the assembly sleeve. The outer shell and the assembly sleeve are produced separately, which facilitates the assembly of the outer shell and the terminals during assembly.

[0015] Preferably, the mounting block is slidably inserted into the mounting groove, the assembly sleeve is provided with a ventilation groove, and the outer shell is provided with a locking component, which is used to lock and fix the assembly sleeve.

[0016] By adopting the above technical solution, when it is necessary to further improve the heat dissipation effect of the overall heat dissipation structure during long-term high-current charging or under high temperature conditions, the locking component can be released, the assembly sleeve can be pushed to slide, and airflow can be blown into the interior of the outer shell through the ventilation slot, thereby further improving the heat dissipation effect of the overall structure.

[0017] Preferably, the locking assembly includes a locking block and a locking spring. The outer casing is provided with a locking groove. The locking block is slidably disposed in the locking groove and can be inserted into the mounting groove. The locking spring is disposed in the locking groove and connects the inner wall of the locking groove to the locking block.

[0018] By adopting the above technical solution, the locking spring pushes the locking block out of the locking groove and into the mounting groove. The locking block abuts against the inner wall of the mounting groove, thereby abutting the entire assembly sleeve and locking it to the outer shell. The operation is simple and convenient. When it is necessary to release the lock, push the locking block to compress the locking spring, causing the locking block to disengage from the mounting groove. At this time, the assembly sleeve can be pushed to slide until the inner wall of the mounting groove abuts against the mounting block, thereby allowing the ventilation groove to connect with the inside of the outer shell, increasing the airflow speed and accelerating heat dissipation.

[0019] Preferably, both the locking block and the mounting block are provided with inclined surfaces.

[0020] By adopting the above technical solution, the inclined surface facilitates the installation of the assembly sleeve, and the mounting block and locking block are inserted into the mounting groove, thus improving the ease of assembly.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up an outer shell, a heat sink, a first assembly hole, a heat sink fin, and a heat sink groove, the outer shell serves as part of the charging gun socket. The terminals of the charging gun socket pass through the first mounting hole of the heat sink. The heat sink is made of ceramic material, which ensures insulation while dissipating heat through the heat sink fin passing through the heat sink groove, thus having good heat dissipation performance. 2. By setting up an assembly sleeve, a second assembly hole, a mounting groove, a ventilation groove, a mounting block, and a locking component, the terminal passes through the second assembly hole of the assembly sleeve. When long-term high-power charging is required, the locking component is released, and the assembly sleeve is pushed to move until the inner wall of the mounting groove abuts against the mounting block, so that the ventilation groove can guide airflow into the housing for heat dissipation and improve heat dissipation performance. 3. By setting a locking groove, a locking block, and a locking spring, the locking block is pushed to insert into the locking groove and compress the locking spring. After the locking block disengages from the mounting groove, it no longer locks the assembly sleeve. At this time, the assembly sleeve can be pushed to move and release the locking of the assembly sleeve. At the same time, when locking is required, the assembly sleeve is slid to make the assembly sleeve abut against the outer shell. At this time, the assembly sleeve no longer abuts against the locking block. The locking spring returns to its original position and pushes the locking block into the mounting groove and abuts against the inner wall of the mounting groove to complete the locking.

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] This application discloses a heat dissipation structure for an electric vehicle charging socket. (Refer to...) Figure 1 and Figure 2 The device includes a housing 1 and a heat sink 2. The housing 1 is part of the charging gun socket, and one end of the housing 1 has an opening slot 14 for the charging gun socket terminals to pass through. The heat sink 2 is located inside the housing 1 and has two through-holes 22 for the terminals to pass through. Multiple heat sinks 21 are radially fixed on the outer surface of the heat sink 2, and the housing 1 has several heat dissipation grooves 11 for the heat sinks 21 to fit through. The housing 1 is made of an engineering plastic (such as PPS or PEEK) with a coefficient of thermal expansion close to that of ceramic, while the heat sink 2 and heat sinks 21 are made of alumina ceramic. The housing 1 and heat sink 2 are integrally injection molded using an embedded insert. The ceramic material provides both insulation and heat dissipation, allowing the heat generated by the terminals to be dissipated from the housing 1 through the heat sink 2 and heat sinks 21, thus achieving heat dissipation.

[0028] To further improve heat dissipation performance, refer to Figure 2 A ring of assembly adhesive 23 is fixedly disposed on the inner wall of the first assembly hole 22. The assembly adhesive 23 is made of silicone-based high thermal conductivity adhesive material with a thermal conductivity >10W / mK. The assembly adhesive 23 abuts against the inner wall of the first assembly hole 22 and the terminal. The assembly adhesive 23 improves the connection stability between the terminal and the heat sink 2 while having good heat dissipation performance.

[0029] To further improve heat dissipation performance, refer to Figure 1 and Figure 3An assembly sleeve 3 is slidably fitted onto one side of the opening slot 14 of the outer casing 1 to close the opening slot 14. The assembly sleeve 3 has a second assembly hole 33 through which a terminal adapter passes. Multiple mounting slots 31 are provided through the side wall of the assembly sleeve 3. Multiple mounting blocks 13 are fixedly mounted on the surface of the outer casing 1, which are inserted into and slide within the mounting slots 31. The assembly sleeve 3 has multiple ventilation slots 32 communicating with the interior of the outer casing 1. The outer casing 1 has a locking component 4 for locking and fixing the assembly sleeve 3. When the outer casing 1 locks the assembly sleeve 3, the ventilation slots 32 and mounting slots 31 are both abutted by the surface of the outer casing 1. When the locking is released, the assembly sleeve 3 can be pushed until the inner wall of the mounting slot 31 abuts against the mounting block 13, thereby connecting the ventilation slots 32 and mounting slots 31 to the interior of the outer casing 1, allowing airflow to circulate inside the outer casing 1, accelerating heat dissipation, and further improving heat dissipation performance.

[0030] For ease of use, please refer to Figures 1 to 3 The locking assembly 4 includes a locking block 41 and a locking spring 42. A locking groove 12 is provided on the surface of the housing 1 on the side of the mounting block 13 away from the opening groove 14. The locking block 41 is slidably disposed in the locking groove 12 and can be inserted into the mounting groove 31. The locking spring 42 is disposed within the locking groove 12 and connects the inner wall of the locking groove 12 to the locking block 41. Both the locking block 41 and the mounting block 13 have inclined surfaces 131. Pushing the locking block 41 compresses the locking spring 42, causing the locking block 41 to disengage from the mounting groove 31. At this time, pushing the assembly sleeve 3 slides until the inner wall of the mounting groove 31 abuts against the mounting block 13. During this process, the assembly sleeve 3 abuts against the locking block 41, thereby allowing the ventilation groove 32 to connect to the interior of the housing 1, increasing airflow speed, accelerating heat dissipation, and making operation simple, convenient, and easy to use.

[0031] The implementation principle of the heat dissipation structure of an electric vehicle charging socket in this application embodiment is as follows: ceramic and plastic are embedded and molded to achieve a stable combination of ceramic and plastic. The heat dissipation block 2 and the outer shell 1 are embedded and molded. At the same time, the heat dissipation block 2 and the heat dissipation fin 21 made of ceramic utilize the high thermal conductivity and insulation properties of ceramic and the molding advantages of plastic to achieve heat dissipation, insulation and sealing, thereby improving the heat dissipation and insulation of the overall heat dissipation structure.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
