Description

[0002] With the booming development of the electric vehicle market, the demand for efficient and fast high-power charging is becoming increasingly urgent. However, existing charging socket technologies have revealed a series of problems that urgently need to be solved when dealing with high-power charging.

[0003] Existing charging sockets have significant shortcomings in their cooling methods. Traditional passive cooling methods, such as natural heat dissipation or air convection, are no longer sufficient to meet the demands of high-power transmission. As the charging current increases, the heat generated by the charging socket also increases, causing the temperature to rise rapidly. This overheating can not only damage the electronic components of the charging device but may also lead to safety accidents, such as burnout or even fire.

[0004] However, existing charging sockets lack effective heat dissipation mechanisms in their structural design. Most of the heat accumulates inside the socket and cannot be dissipated in time, which not only affects the performance of the charging socket but also shortens its lifespan. Furthermore, existing designs cannot achieve a continuous and stable charging process in high-power charging scenarios, limiting the charging efficiency of electric vehicles and the user experience.

[0034] This utility model proposes a charging socket.

[0035] Please see Figures 1 to 4In one embodiment of the present invention, the charging socket includes a socket housing 10, at least two DC terminals 20, and a liquid cooling assembly 30; the two DC terminals 20 are respectively connected to the socket housing 10; the liquid cooling assembly 30 includes a terminal connecting block 31, a coolant input component 32, and a cooling block 33. The terminal connecting block 31 is used to connect the two DC terminals 20, and the two DC terminals 20 are connected to the coolant input component. The terminal connecting block 31 and the two DC terminals 20 enclose a mounting groove, and the cooling block 33 is installed in the mounting groove; the cooling block 33 has an internal circuit 33a, and the internal circuit 33a communicates with the coolant input component 32 to form a liquid cooling channel.

[0036] In this embodiment, the socket housing 10 serves as the basic structure of the entire charging socket and is made of high-strength material, possessing excellent heat resistance and mechanical strength. The housing not only provides support and protection for the internal components but also ensures waterproof and dustproof performance during operation through a sealed design, thereby enhancing safety. The charging socket also includes a tail cover 11 fixedly connected to the socket housing 10. The tail cover 11 is inserted into two DC terminals 20, fixing the DC terminals 20 inside the socket housing 10.

[0037] The charging socket includes at least two DC terminals 20, one for transmitting positive current and the other for transmitting negative current. The DC terminals 20 are made of a highly conductive material to ensure efficient current transmission. The terminal surfaces are specially treated to reduce contact resistance and improve heat dissipation.

[0038] The liquid cooling assembly 30 is the core innovation of this solution. Its terminal connector 31 connects two DC terminals 20, ensuring stable current transmission. The end of the coolant inlet 32 ​​furthest from the terminal connector 31 forms the inlet of the liquid cooling channel. The coolant inlet 32, as the component through which coolant enters the liquid cooling assembly 30, has a precisely designed internal flow channel to ensure uniform coolant distribution and efficient heat removal. The cooling block 33 of the liquid cooling assembly 30 is installed within the mounting groove formed by the terminal connector 31 and the DC terminals 20. The cooling block 33 has an internal circuit 33a designed to guide coolant flow and absorb heat.

[0039] When the charging socket is operational, current is transferred to the vehicle battery through the DC terminal 20. Due to the significant heat generated during high-power transmission, the liquid cooling assembly 30 activates. Coolant enters the internal circuit 33a of the cooling block 33 through one end of the coolant inlet 32, allowing the coolant to indirectly contact the two DC terminals 20 via the cooling block 33 for heat exchange and cooling, continuously removing the heat generated by the DC terminals 20 during high-power transmission. The cooled coolant, having absorbed heat, exits through the other end of the coolant inlet 32, forming a circulation, thereby continuously removing heat and ensuring that the temperature of the DC terminals 20 remains within a controllable range.

[0040] The charging socket of this invention utilizes an innovative design in the liquid cooling component 30, allowing the coolant to circulate within the DC terminal 20. This continuously removes heat generated during high-power transmission, ensuring the charging socket temperature remains within a safe range. Compared to traditional passive cooling methods (such as natural or air cooling), this active cooling method achieves highly efficient heat dissipation during high-power transmission, meeting the demands of high-power charging for electric vehicles. Furthermore, the coordinated design of the terminal connection block 31 and the cooling block 33 not only optimizes the layout of the liquid cooling channels but also enhances the mechanical strength of the DC terminal 20.

[0041] In one embodiment, please refer to Figures 1 to 4 The cooling block 33 also has two connecting ports 33b, which are connected to the internal circuit 33a and are located on opposite sides of the cooling block 33 respectively; the two connecting ports 33b are connected to the coolant inlet 32 ​​so that the coolant inlet 32 ​​is connected to the internal circuit 33a.

[0042] Two connecting ports 33b are provided on each side of the cooling block 33. These two connecting ports 33b are connected to the internal circuit 33a, forming the inlet and outlet of the internal circuit 33a. The position design of the connecting ports 33b ensures that the coolant can be evenly distributed and efficiently cover the heat-generating area of ​​the DC terminal 20. This design allows the coolant to continuously flow in and out of the cooling block 33, forming an efficient cooling cycle.

[0043] Coolant enters through coolant inlet 32 ​​into one port 33b of cooling block 33, and then into internal circuit 33a. The coolant flows within the S-shaped or Z-shaped internal circuit 33a of cooling block 33, absorbing heat generated by DC terminal 20. After absorbing heat, the coolant flows out through another port 33b of cooling block 33 and is discharged through liquid cooling pipe 322, forming a complete cooling circuit.

[0044] In this embodiment, by providing connecting ports 33b on both sides of the cooling block 33, the coolant can be evenly distributed and efficiently cover the heat-generating area of ​​the DC terminal 20, avoiding local overheating and achieving efficient heat dissipation. At the same time, the structural design is optimized, improving stability and safety.

[0045] Further, please refer to Figures 1 to 4 The internal circuit 33a is an S-shaped circuit or a Z-shaped circuit.

[0046] Specifically, the cooling block 33 has spaced protrusions inside, and the sidewalls of these protrusions have gaps with the inner wall of the cooling block 33, dividing the internal circuit 33a into multiple continuous flow channels. Preferably, the internal circuit 33a is an S-shaped circuit or a Z-shaped circuit.

[0047] S-shaped circuit: The coolant forms a continuous S-shaped path inside the cooling block 33 to ensure that the coolant can evenly cover the entire heat-generating area of ​​the DC terminal 20 and avoid local overheating.

[0048] Z-shaped circuit: The coolant forms a Z-shaped path inside the cooling block 33. Through multiple zigzag flows, the flow path length of the coolant is further increased, improving the heat dissipation effect.

[0049] The cooling block 33 is installed in the mounting groove formed by the terminal connecting block 31 and the DC terminal 20, and fits tightly against the DC terminal 20. The cooling block 33 has several protrusions inside, forming an S-shaped or Z-shaped loop design to ensure that the coolant can indirectly contact the heat-generating area of ​​the DC terminal 20, thereby achieving efficient heat dissipation.

[0050] In this embodiment, the internal circuit 33a of the cooling block 33 is designed in an S-shape or Z-shape to increase the flow path length of the coolant and extend the contact time between the coolant and the DC terminal 20, allowing heat to be carried away more effectively by the coolant. Compared with the traditional straight circuit, the S-shape or Z-shape circuit can significantly improve heat dissipation efficiency and ensure that the temperature of the DC terminal 20 remains within a safe range during high-power transmission.

[0051] In one embodiment, please refer to Figures 1 to 4 The coolant input component 32 includes two coolant inlets 321 and two liquid cooling pipes 322. Each coolant inlet 321 is connected to a communication port 33b. Each liquid cooling pipe 322 is connected to the end of a coolant inlet 321 away from the DC terminal 20 and is connected to the coolant inlet 321.

[0052] One of the liquid cooling pipes 322 serves as the inlet pipe of the liquid cooling channel of the liquid cooling assembly 30, and the other liquid cooling pipe 322 serves as the outlet pipe of the liquid cooling channel of the liquid cooling assembly 30, so that the two liquid cooling pipes 322, the cooling block 33 and the two coolant inlets 321 form a complete and effective liquid cooling channel.

[0053] This embodiment achieves a more compact structure for the entire liquid cooling assembly 30 and optimizes space utilization through the direct connection between the coolant inlet 321 and the tail cap 11, as well as the external arrangement of the liquid cooling pipe 322.

[0054] In one embodiment, please refer to Figures 1 to 4 The liquid cooling assembly 30 also includes two spring tubes 34, each spring tube 34 being sleeved on a liquid cooling tube 322.

[0055] Each liquid cooling tube 322 is externally fitted with a spring tube 34, which is made of high-strength, corrosion-resistant material. Under complex operating conditions (such as vibration, impact, etc.), the spring tube 34 can effectively absorb external impact forces through its special structure, enabling the liquid cooling tube 322 to maintain good sealing and stability under complex operating conditions, protecting the liquid cooling tube 322 from damage, thereby improving the overall stability of the liquid cooling system.

[0056] The liquid cooling tube 322 is responsible for delivering coolant, while the spring tube 34 provides additional mechanical protection for the liquid cooling tube 322. This design not only extends the service life of the liquid cooling tube 322 but also ensures the continuity and stability of coolant flow.

[0057] In another embodiment, the spring tube 34 can be replaced by a metal bellows.

[0058] In one embodiment, please refer to Figures 1 to 4 Each coolant inlet 321 includes an inlet pipe section 321a, an inlet body 321b, and an outlet pipe section 321c connected in sequence. The inlet pipe section 321a and the outlet pipe section 321c are arranged vertically. The inlet pipe section 321a is inserted into the DC terminal 20 and abuts against the cooling block 33, and the inlet pipe section 321a is connected to the connecting port 33b. The outlet pipe section 321c is connected to a liquid cooling pipe 322.

[0059] Each coolant inlet 321 includes an inlet pipe section 321a, an inlet body 321b, and an outlet pipe section 321c connected in sequence. The inlet pipe section 321a and the outlet pipe section 321c are arranged vertically. This design optimizes the flow path of the coolant and ensures that the coolant can enter and exit the cooling block 33 efficiently.

[0060] The inlet pipe section 321a is inserted into the DC terminal 20 and abuts against the cooling block 33. The inlet pipe section 321a communicates with the connecting port 33b on the cooling block 33, ensuring that the coolant can smoothly enter the S-shaped or Z-shaped circuit inside the cooling block 33. This design allows the coolant to directly contact the heat-generating area of ​​the DC terminal 20, achieving efficient heat dissipation. The outlet pipe section 321c connects to the liquid cooling pipe 322 and is used to guide the coolant, after absorbing heat, to the external cooling system, forming a complete cooling circuit. The design of the outlet pipe section 321c ensures the continuity and stability of the coolant flow.

[0061] By optimizing the design of the coolant inlet 321, with the inlet pipe section 321a and the outlet pipe section 321c arranged perpendicularly, space utilization is optimized, interference between components is reduced, and the overall structure of the liquid cooling assembly 30 becomes more compact. This also improves the efficiency of coolant flow. The vertical arrangement also makes the installation of the coolant inlet 321 easier and reduces assembly errors.

[0062] For further details, please refer to Figures 1 to 4 The liquid cooling assembly 30 also includes two first sealing rings, each of which abuts between the inlet body 321b and the tail cap 11 to seal the gap between the inlet body 321b and the tail cap 11, ensuring that the coolant does not leak.

[0063] Furthermore, the liquid cooling assembly 30 also includes two second sealing rings, each of which is fitted onto the outer wall of an inlet pipe section 321a to seal the gap between the inlet pipe section 321a and the cooling block 33, ensuring that the coolant does not leak.

[0064] In one embodiment, each DC terminal 20 is provided with a first through groove 20a; the terminal connecting block 31 is provided with a second through groove 31a coaxially arranged with the first through groove 20a, and the two first through grooves 20a and the second through groove 31a are connected to form an installation groove; the two ends of the cooling block 33 are located in the two first through grooves 20a, the liquid inlet pipe section 321a extends into the first through groove 20a and abuts against one end of the cooling block 33, and is connected to the connecting port 33b.

[0065] Each DC terminal 20 has a first through slot 20a inside, and a second through slot 31a communicates with the first through slots 20a of the two DC terminals 20 to form a complete mounting slot for mounting the cooling block 33. The cooling liquid is then guided to flow and absorb heat through the internal circuit 33a of the cooling block 33. This design allows the cooling liquid to directly contact the heat-generating area of ​​the DC terminal 20, achieving efficient heat dissipation.

[0066] Through the coordinated design of the first through slot 20a and the second through slot 31a, the cooling block 33 can contact the two DC terminals 20 and the terminal connection block 31, and the coolant can be evenly distributed and efficiently cover the heat-generating area of ​​the DC terminal 20, avoiding local overheating.

[0067] The inlet pipe section 321a is inserted into the first through slot 20a of the DC terminal 20 and abuts against the cooling block 33. This ensures the formation of a complete liquid cooling channel while optimizing space utilization, making the entire liquid cooling assembly 30 more compact. The tight contact between the inlet pipe section 321a and the cooling block 33, and the stable connection between the outlet pipe section 321c and the liquid cooling pipe 322, ensure the sealing of the coolant under high-pressure conditions and prevent leakage.

[0068] The terminal connection block 31 here includes a connection block body and at least two plug-in pins. The connection block body is provided with a second through groove 31a. The two plug-in pins are located on opposite sides of the connection block body and are spaced apart from the second through groove 31a. Each plug-in pin is inserted into one side of a DC terminal 20, and the connection block body is sealed and abutted against one side of the two DC terminals 20.

[0069] Furthermore, the terminal connecting block 31 and the DC terminal 20 are fixedly connected by screws.

[0070] In one embodiment, please refer to Figures 1 to 4 The circumferential outer wall of the liquid inlet pipe section 321a is provided with multiple flanges, which are arranged at intervals along the axial direction of the liquid inlet pipe section 321a and abut against the inner wall of the internal circuit 33a.

[0071] In further optimized design, the circumferential outer wall of the liquid inlet pipe section 321a is provided with multiple flanges. These flanges are arranged at intervals along the axial direction of the liquid inlet pipe section 321a and abut against the inner wall of the cooling block 33. The main function of these flanges is to increase the contact area between the liquid inlet pipe section 321a and the inner wall of the cooling block 33, thereby improving sealing performance and connection strength.

[0072] Meanwhile, the flange fits tightly against the inner wall of the cooling block 33, ensuring that the coolant will not leak under high-pressure conditions. This tight fit also evenly distributes pressure, reduces local stress concentration, and extends the service life of the components.

[0073] Furthermore, the multiple flanges on the circumferential outer wall of the inlet pipe section 321a are designed with gradually decreasing diameters to form a pagoda-shaped structure. This structure provides better sealing and stability under high-pressure conditions. The pagoda-shaped structure effectively disperses the pressure at the connection point, reducing the risk of leakage.

[0074] In this embodiment, by setting multiple flanges on the circumferential outer wall of the liquid inlet pipe section 321a and adopting a pagoda-shaped structure to optimize the design of the connection, the liquid cooling component 30 of this utility model can achieve efficient heat dissipation during high power transmission, while optimizing the structural design and improving stability and safety.

[0075] In one embodiment, please refer to Figures 1 to 4 The second through groove 31a has a plurality of protrusions 31b arranged at intervals on its groove wall. The protrusions 31b extend along the axial direction of the second through groove 31a. The outer wall of the cooling block 33 has a plurality of slots 33c. Each protrusion 31b is engaged in a slot 33c so that the cooling block 33 is engaged in the terminal connecting block 31.

[0076] In further optimized design, the second through groove 31a has multiple spaced protrusions 31b on its wall, which extend axially along the second through groove 31a. The main function of the protrusions 31b is to increase the contact area between the cooling block 33 and the terminal connecting block 31, thereby improving the connection strength and stability. The outer wall of the cooling block 33 has multiple slots 33c, which match the protrusions 31b in the second through groove 31a. Each protrusion 31b engages in a slot 33c, allowing the cooling block 33 to be securely installed in the terminal connecting block 31.

[0077] In this embodiment, multiple protrusions 31b are provided on the wall of the second through groove 31a, and multiple slots 33c are provided on the outer wall of the cooling block 33, so that the cooling block 33 can be securely engaged in the terminal connecting block 31. This design not only enhances the connection strength between the cooling block 33 and the terminal connecting block 31, but also optimizes the flow path of the coolant and improves the heat dissipation efficiency.

[0078] In one embodiment, please refer to Figures 1 to 4 The charging socket also includes a PCB circuit board 40, which is mounted on the socket housing 10. Two DC terminals 20 pass through the PCB circuit board 40 and are connected to the socket housing 10 and electrically connected to the PCB circuit board 40.

[0079] The PCB circuit board 40 is installed inside the socket housing 10, serving as the core of the electrical connection for the entire charging socket. It connects various electronic components via conductive copper foil and different circuit paths, enabling the flow of current and the transmission of signals. Two DC terminals 20 pass through the PCB circuit board 40 and are connected to the socket housing 10. This design allows current to be transmitted through the PCB circuit board 40 to the DC terminals 20, and then to the vehicle battery. Simultaneously, the PCB circuit board 40, positioned between the socket housing 10 and the tail cap 11, provides stable mechanical support, ensuring reliable connection.

[0080] In one embodiment, please refer to Figures 1 to 4 The charging socket also includes a temperature sensor 50, which is integrated on the PCB circuit board 40 and electrically connected to the PCB circuit board 40 and external circuits to monitor the real-time temperature of the PCB circuit board 40.

[0081] The temperature sensor 50 in this solution is fixed on the surface of the PCB circuit board 40, and the wires of the temperature sensor 50 and other signal terminals are integrated into the PCB circuit board 40 and connected to the outside through pins. On the one hand, this simplifies and optimizes the internal wiring layout of the charging socket, reduces the risk of signal wire bending and tangling, and improves the stability of signal transmission and temperature detection. On the other hand, the connection to the outside through pins improves the internal sealing of the charging socket.

[0082] Optionally, the temperature sensor 50 is a surface-mount thermistor. The thermistor is protected by a silicone sleeve.

[0083] The socket housing 10 is also connected to the tail cover and cable sealing cover by a snap-fit ​​mechanism, making installation and disassembly convenient. Furthermore, the charging socket incorporates a leakage detection board integrated into the PCB board to monitor the operation of the liquid cooling system.

[0084] Assembly Process: Install the flange and top cover plate onto the socket housing 10. Install the mounting gasket onto the flange and top cover plate.

[0085] This solution connects the charging socket end cap and cable sealing cover to the socket housing 10 and end cap via clips, reducing the number of parts while ensuring connection strength, effectively reducing the difficulty of installation and disassembly. In addition, a leakage detection plate is provided at the end of the socket to prevent leakage, improving the safety of the socket during operation.
