[0015] Compared with the prior art, the car charger adapter provided by this utility model has the following advantages:

[0016] 1. This utility model provides a car charger adapter. By setting conductive components, the wiring harness inside the car charger adapter can be reduced, facilitating wiring production and reducing the overall size of the car charger adapter. By setting a first mounting groove and a second mounting groove on the insulating first inner shell and second inner shell respectively for placing the first adapter post and the second adapter post of the conductive components, the first adapter post and the second adapter post can be separated to avoid the risk of short circuit and leakage fire, forming an insulating gap between the first adapter post and the second adapter post. The second inner shell is connected to the first inner shell through a first cover plate, and the third inner shell is connected to the second inner shell through a second cover plate, so as to hold the first adapter post. The first and second adapter posts are respectively fixed in the first and second mounting slots, which can prevent the first and second adapter posts from shifting and affecting the electrical conductivity. It can also provide physical protection for the first and second adapter posts to avoid leakage or poor contact caused by external impacts. The first sleeve assembly is sleeved on the first and second input terminals to form an insulating gap between them, and the second sleeve assembly is sleeved on the first and second output terminals to form an insulating gap between them. This can effectively isolate the different electrodes of the conductive components, further avoid the risk of short circuits and leakage fires, and improve the safety of users charging new energy vehicles with the car charger adapter.

[0017] 2. In the car charger adapter provided in this embodiment of the present invention, the first main sleeve and the second auxiliary sleeve are respectively sleeved on the side of the first input end and the first output end near the first adapter post, and the first auxiliary sleeve and the second main sleeve are respectively sleeved on the side of the second input end and the second output end near the second adapter post. The first main sleeve and the first auxiliary sleeve are used to form an insulating gap between the first input end and the second input end, and the second main sleeve and the second auxiliary sleeve are used to form an insulating gap between the first output end and the second output end. This can reduce or even eliminate the risk of short circuit between adjacent electrodes due to excessively close spacing. The first sleeve assembly and the second sleeve assembly separate the two conductive paths on the side near the first adapter post and the second adapter post, respectively, which can avoid crosstalk of electrical signals or interference of current and improve the stability of the car charger adapter in transmitting current through the two conductive paths simultaneously.

[0018] 3. In the car charger adapter provided in this embodiment of the present invention, the first input end and the first output end are respectively arranged on opposite sides of the first adapter post, and the second input end and the second output end are respectively arranged on opposite sides of the second adapter post. This can shorten the current transmission distance of each conductive path, correspondingly reduce energy consumption, and thus improve conductivity efficiency and conductivity stability. It can also meet the requirement that the input end and the output end correspond to different standard charging interfaces, thereby improving the compatibility of the car charger adapter with different standard interfaces.

[0019] It should be noted that the two ends of the first adapter post are connected to the first input end and the first output end, respectively, and the two ends of the second adapter post are connected to the second input end and the second output end, respectively. This is to facilitate the early determination of the positions of the first cover plate, the second cover plate, the first sleeve assembly, and the second sleeve assembly, thereby simplifying the manufacturing and assembly process of each component of the vehicle charger adapter and improving the efficiency of assembly line production.

[0020] 4. In the vehicle charger adapter provided in this embodiment of the present invention, the first mounting groove and the second mounting groove are arranged crosswise in the length direction, so that the first adapter post and the second adapter post are arranged in an up-down crosswise layout. This makes the vehicle charger adapter more stable when performing current and voltage conversion, and minimizes the area when the first adapter post and the second adapter post overlap, avoiding electromagnetic coupling between the first adapter post and the second adapter post. It also reduces wiring in the structure and reduces the horizontal space occupied, which is suitable for the miniaturization and integration design requirements of the vehicle charger adapter. The first cover plate set on the second inner shell forms an insulating gap between the first mounting groove and the second mounting groove, which can prevent the distance between the first adapter post and the second adapter post from being too close, further eliminating electrical signal crosstalk or current interference, and reducing the risk of short circuit.

[0021] Understandably, the first adapter post and the second adapter post are located on both sides of the second inner shell, and are located in the first mounting slot and the second mounting slot, respectively. Therefore, it can be seen that the first adapter post and the second adapter post are not placed on the same horizontal plane. By setting the length of the first input end to be less than that of the second input end and the length of the first output end to be greater than that of the second output end, it can be ensured that the ends of the first input end and the second input end, and the ends of the first output end and the second output end are respectively flush.

[0022] 5. In the vehicle charger adapter provided in this embodiment of the present invention, the first outer shell and the second outer shell of the outer shell assembly are connected back to back to form an accommodating space, so as to facilitate the installation and fixing of the conductive component and the inner shell assembly. At the same time, the rigid support of the outer shell assembly can provide physical protection for the conductive component and the inner shell assembly, resisting external vibration and impact, and can also enhance the overall structural strength of the vehicle charger adapter, adapting to harsh weather and complex environments. The outer shell assembly and the inner shell assembly cooperate to form a dual protection system of "external protection and internal insulation", further isolating the conductive component from the external environment, reducing the risk of leakage, fire and short circuit, and meeting the safety standards of the vehicle charger adapter. The first charging connector and the second charging connector are respectively arranged on the outside of the first outer shell and the second outer shell, wherein the first charging connector is used to connect to the vehicle that needs to be charged, and the second charging connector is used to connect to the charging facility.

[0023] 6. In the vehicle charging adapter provided in this embodiment of the utility model, by setting a first DC voltage port, a second DC voltage port, a first auxiliary port, and a second auxiliary port, the vehicle charging adapter can conform to industry-standard specifications and be compatible with multiple charging adapter protocols. It can transmit power and realize data interaction, further improving the compatibility of the vehicle charging adapter with different standard interfaces. The first DC voltage port and the second DC voltage port serve as the main channels for transmitting electrical energy. When the first charging connector of the vehicle charging adapter is connected to the vehicle that needs to be charged, and the second charging connector is connected to the charging facility, high-voltage DC charging can be supported. The first auxiliary port and the second auxiliary port integrate communication, grounding, and control functions, supporting functions such as charging connection confirmation and overvoltage protection during the charging process of new energy vehicles, realizing intelligent interaction between the vehicle and the charging facility.

[0024] Understandably, the first and second communication ports can transmit voltage signals during charging and monitor the charging status. They can also dynamically adjust the charging power to optimize charging efficiency. The first and second grounding ports can provide a reliable grounding path to prevent leakage or static electricity accumulation, thereby reducing the risk of electric shock and ensuring safe and reliable charging. The first and second control ports can control the on / off state of the charging circuit to avoid accidental charging in the absence of connection or in abnormal conditions, further improving the safety of the vehicle charger adapter.

[0025] 7. In the car charger adapter provided in this embodiment of the present invention, the first input terminal and the second input terminal extend to the first DC+ port and the first DC- port, respectively, and the first output terminal and the second output terminal extend to the second DC+ port and the second DC- port, respectively. The first adapter post and the second adapter post serve as intermediate connection hubs, facilitating standardized connection, shortening the current transmission distance, and improving the transmission efficiency of DC power. At the same time, combined with the design of setting insulation intervals between the first input terminal and the second input terminal, between the first adapter post and the second adapter post, and between the first output terminal and the second output terminal inside the housing space, it can achieve efficient conductivity and maintain physical and electrical isolation between positive and negative polarity ports, which meets the safety specifications of car charger adapters under high voltage DC charging, and ensures that the use of the car charger adapter is more stable and reliable.

[0026] 8. In the vehicle charger adapter provided in this embodiment of the present invention, the independent first wire harness, second wire harness and third wire harness are respectively connected to the communication, control and grounding ports, which can form a dedicated signal transmission channel to ensure that data interaction, connection status control and grounding protection functions can be stably realized during the charging process, and to avoid signal interference or attenuation; it can also facilitate the rapid docking of the communication, control and grounding ports during production and assembly, so as to avoid the risk of reverse polarity or port function misalignment.

[0027] 9. In the vehicle charger adapter provided in this embodiment of the present invention, the first charging connector is connected to the new energy vehicle that needs to be charged, and the second charging connector is connected to the charging facility to support high-voltage DC charging. When using the vehicle charger adapter, the first charging connector is inserted into the charging port of the new energy vehicle, and the charging gun of the charging facility is inserted into the second charging connector. Through the first locking end on the first locking member and the second locking end on the second locking member, the first charging connector and the second charging connector can be prevented from becoming loose or falling off due to typhoons, rainstorms, or other situations, thereby strengthening the connection reliability of the first charging connector and the second charging connector and improving the connection strength of the vehicle charger adapter. The exposed design of the first button end and the second button end facilitates one-handed operation by the user, enabling quick unlocking and plugging / unplugging between the first charging connector and the charging port of the new energy vehicle, and between the second charging connector and the charging gun, thereby improving the ease of use of the vehicle charger adapter.

[0028] 10. In the car charger adapter provided in this embodiment of the present invention, the first input terminal, first adapter post, first output terminal, second input terminal, second adapter post, and second output terminal, made of copper or copper alloy, have excellent conductivity, which can reduce current transmission resistance, reduce heat generation and energy loss, and facilitate current transmission. This ensures that the first input terminal, first adapter post, first output terminal, second input terminal, second adapter post, and second output terminal can work stably for a long time, improve charging efficiency and charging stability, and enhance the reliability of the car charger adapter. The first and second locking parts, made of hard materials, have good deformation resistance and heat resistance, ensuring that the locking end and the button end maintain mechanical strength during frequent insertion and removal operations, strengthening connection stability, and preventing the first and second charging connectors from losing their quick unlocking and insertion / removal functions due to material softening or breakage, thereby extending the service life of the car charger adapter.

[0048] Please see Figure 1 and Figure 2This utility model provides a car charger adapter 100, which includes a conductive component 1 and an inner shell component 2. The conductive component 1 includes a first input terminal 11, a first adapter post 13, and a first output terminal 15 connected in sequence and electrically connected, and a second input terminal 12, a second adapter post 14, and a second output terminal 16 connected in sequence and electrically connected. The inner shell component 2 includes an insulated first inner shell 21, a second inner shell 22, and a third inner shell 23. The first inner shell 21 is provided with a first mounting groove 211 for placing the first adapter post 13, and the second inner shell 22 is provided with a mounting groove for placing the first adapter post 13. The second adapter post 14 has a second mounting groove 221; the second inner shell 22 is provided with a first cover plate 222 connected to the first inner shell 21, and the third inner shell 23 is provided with a second cover plate 231 connected to the second inner shell 22. The first cover plate 222 and the second cover plate 231 correspond to the first mounting groove 211 and the second mounting groove 221, respectively; the first inner shell 21 is provided with a first sleeve assembly 212 sleeved on the first input end 11 and the second input end 12, and the third inner shell 23 is provided with a second sleeve assembly 232 sleeved on the first output end 15 and the second output end 16 to form an insulating gap.

[0049] In the car charger adapter 100 provided in this embodiment of the utility model, the number of wire harnesses inside the car charger adapter 100 can be reduced by setting the conductive component 1, which facilitates wiring production and reduces the overall volume of the car charger adapter 100. By setting a first mounting groove 211 and a second mounting groove 221 on the insulating first inner shell 21 and the insulating second inner shell 22 respectively, the first mounting groove 211 is used to place the first adapter post 13 of the conductive component 1, and the second mounting groove 221 is used to place the second adapter post 14 of the conductive component 1. This design can isolate the first adapter post 13 and the second adapter post 14 to avoid the risk of short circuit and leakage fire, and form an insulating gap between the first adapter post 13 and the second adapter post 14.

[0050] Understandably, in this embodiment of the present invention, both the first cover plate 222 and the second cover plate 231 are made of insulating material. The insulating second inner shell 22 is connected to the first inner shell 21 through the first cover plate 222 to stabilize the first adapter post 13 in the first mounting groove 211. The insulating third inner shell 23 is connected to the second inner shell 22 through the second cover plate 231 to stabilize the second adapter post 14 in the second mounting groove 221. This can prevent the first adapter post 13 and the second adapter post 14 from being affected by displacement, thus avoiding impact on their electrical conductivity. It can also provide physical protection for the first adapter post 13 and the second adapter post 14 to prevent leakage or poor contact caused by external impact.

[0051] It should be noted that both the first sleeve assembly 212 and the second sleeve assembly 232 are made of insulating material. The first sleeve assembly 212 is sleeved on the first input terminal 11 and the second input terminal 12 to form an insulating gap between the first input terminal 11 and the second input terminal 12. The second sleeve assembly 232 is sleeved on the first output terminal 15 and the second output terminal 16 to form an insulating gap between the first output terminal 15 and the second output terminal 16. In this embodiment of the present invention, the working ends of the first input terminal 11, the second input terminal 12, the first output terminal 15, and the second output terminal 16 are all exposed. Through this design, different electrodes of the conductive component 1 can be effectively isolated, further avoiding the risk of short circuit and leakage fire, and improving the safety of users charging new energy vehicles using the vehicle charging adapter 100.

[0052] In some embodiments, by providing the conductive component 1, the number of wire harnesses inside the vehicle charger adapter 100 can be reduced, facilitating wiring production. This reduces production costs while also enabling the vehicle charger adapter 100 to be miniaturized and lightweight. The first electrically conductive path is defined by sequentially connecting the first input terminal 11, the first adapter post 13, and the first output terminal 15, and the second electrically conductive path is defined by sequentially connecting the second input terminal 12, the second adapter post 14, and the second output terminal 16. By forming insulating gaps between the first and second electrical conductive paths, between the first and second adapter posts 13 and 14, and between the first and second output terminals 15 and 16, this embodiment of the invention ensures that the first and second electrical conductive paths do not interfere with each other, improving the safety of the vehicle charger adapter 100 and solving the technical problem that existing vehicle charger adapters cannot meet the charging safety requirements of new energy vehicles.

[0053] It should be further noted that in the inner shell assembly 2 of this utility model embodiment, the first inner shell 21 and the second inner shell 22 are connected by the first cover plate 222, and the second inner shell 22 and the third inner shell 23 are connected by the second cover plate 231. The first adapter post 13 is placed in the first mounting groove 211 of the first inner shell 21, and the second adapter post 14 is placed in the second mounting groove 221 of the second inner shell 22, which facilitates disassembly during assembly and maintenance in the production process, and enhances the overall structural strength.

[0054] Please see Figure 1 , Figure 2 and Figure 3The first sleeve assembly 212 includes a first main sleeve 2121 and a first auxiliary sleeve 2122, and the second sleeve assembly 232 includes a second main sleeve 2321 and a second auxiliary sleeve 2322. The first main sleeve 2121 and the second auxiliary sleeve 2322 are respectively sleeved on the side of the first input end 11 and the first output end 15 near the first adapter post 13, and the first auxiliary sleeve 2122 and the second main sleeve 2321 are respectively sleeved on the side of the second input end 12 and the second output end 16 near the second adapter post 14.

[0055] In the vehicle charger adapter 100 provided in this embodiment of the present invention, the first main sleeve 2121 and the first auxiliary sleeve 2122 are used to form an insulating gap between the first input terminal 11 and the second input terminal 12, and the second main sleeve 2321 and the second auxiliary sleeve 2322 are used to form an insulating gap between the first output terminal 15 and the second output terminal 16, thereby reducing or even eliminating the risk of short circuit between adjacent electrodes due to excessively close spacing.

[0056] Understandably, the first sleeve assembly 212 and the second sleeve assembly 232 separate the two conductive paths on the side near the first adapter post 13 and the second adapter post 14, respectively, which can avoid crosstalk of electrical signals or interference of current and improve the stability of the car charger adapter 100 in transmitting current through two electrical conductive paths at the same time.

[0057] It should be noted that, based on the inner shell assembly 2's installation and fixation of the first adapter post 13 and the second adapter post 14, the first sleeve assembly 212 is fitted onto the first input end 11 and the second input end 12, and the second sleeve assembly 232 is fitted onto the first output end 15 and the second output end 16. This can enhance the mechanical fixation of the conductive component 1, protect the weak connection areas between the first adapter post 13 and the first input end 11 and the first output end 15, and between the second adapter post 14 and the second input end 12 and the second output end 16, reduce the displacement or poor contact of the conductive component 1 caused by external forces such as vibration and insertion / removal of the car charger adapter device 100, and suppress electromagnetic interference through insulating material to ensure the reliability of current transmission.

[0058] In one embodiment, the first main sleeve 2121 is connected to the first inner shell 21, wherein the side of the first mounting groove 211 away from the first cover plate 222 communicates with the interior of the first main sleeve 2121 so that the first main sleeve 2121 is fitted onto the first input end 11; the first auxiliary sleeve 2122 is connected to the first main sleeve 2121, and the side of the second mounting groove 221 away from the second cover plate 231 communicates with the interior of the first auxiliary sleeve 2122 so that the first auxiliary sleeve 2122 is fitted onto the second input end 12. In one implementation, the second main sleeve 2321 is connected to the third inner shell 23. The side of the second mounting groove 221 near the second cover plate 231 communicates with the interior of the second main sleeve 2321, allowing the second main sleeve 2321 to be fitted onto the second output end 16. The second auxiliary sleeve 2322 is connected to the second main sleeve 2321, and the side of the first mounting groove 211 near the first cover plate 222 communicates with the interior of the second auxiliary sleeve 2322, allowing the second auxiliary sleeve 2322 to be fitted onto the first output end 15. This design allows for further insulation protection of the conductive component 1, building upon the physical insulation separation between the first adapter post 13 and the second adapter post 14. The connection between the first auxiliary sleeve 2122 and the first main sleeve 2121, and the connection between the second auxiliary sleeve 2322 and the second main sleeve 2321, reduces the cost of separately manufacturing auxiliary sleeves and further enhances the stability of the overall internal structure of the vehicle charger adapter device 100.

[0059] Please continue reading. Figure 1 , Figure 2 and Figure 3 The first input terminal 11 and the first output terminal 15 are respectively located on opposite sides of the first adapter post 13. One end of the first adapter post 13 is connected to the first input terminal 11, and the other end is connected to the first output terminal 15. The second input terminal 12 and the second output terminal 16 are respectively located on opposite sides of the second adapter post 14. One end of the second adapter post 14 is connected to the second input terminal 12, and the other end is connected to the second output terminal 16.

[0060] In the vehicle charger adapter 100 provided in this embodiment of the present invention, the first input terminal 11 and the first output terminal 15 are respectively disposed on opposite sides of the first adapter post 13, and the second input terminal 12 and the second output terminal 16 are respectively disposed on opposite sides of the second adapter post 14. This can shorten the current transmission distance of each electrical conduction path, thereby reducing energy consumption and improving conductivity efficiency and conductivity stability.

[0061] In addition, the first input terminal 11 and the first output terminal 15 are respectively located on opposite sides of the first adapter post 13, and the second input terminal 12 and the second output terminal 16 are respectively located on opposite sides of the second adapter post 14. This also allows the input terminal and the output terminal to correspond to charging interfaces of different standards, thereby improving the compatibility of the car charger adapter 100 with different standard interfaces.

[0062] It should be noted that the two ends of the first adapter post 13 are connected to the first input end 11 and the first output end 15, respectively, and the two ends of the second adapter post 14 are connected to the second input end 12 and the second output end 16, respectively. This is to facilitate the early determination of the positions of the first main sleeve 2121 and the first auxiliary sleeve 2122 in the first cover plate 222, the second cover plate 231, the first sleeve assembly 212, and the second main sleeve 2321 and the second auxiliary sleeve 2322 in the second sleeve assembly 232. This simplifies the manufacturing and assembly process of the various components of the vehicle charger adapter device 100 and improves the efficiency of assembly line production.

[0063] Understandably, the conductive component 1, by sequentially connecting and electrically conducting the first input terminal 11, the first adapter post 13, and the first output terminal 15, and sequentially connecting and electrically conducting the second input terminal 12, the second adapter post 14, and the second output terminal 16, can reduce the complex wiring of the conversion process and reduce the assembly difficulty of the internal structure of the car charger adapter device 100. The design of the input and output terminals extending directly to the port can further ensure the uniqueness of the polarity connection, so as to avoid the error of reverse polarity connection during the assembly process.

[0064] Please continue reading. Figure 1 and Figure 2 The first mounting groove 211 forms an insulating gap with the second mounting groove 221 through the first cover plate 222. The first mounting groove 211 and the second mounting groove 221 are arranged to cross each other in the length direction so that the first adapter post 13 and the second adapter post 14 are arranged to cross each other vertically.

[0065] In the car charger adapter 100 provided in this embodiment of the present invention, the first mounting groove 211 and the second mounting groove 221 are arranged crosswise in the length direction, so that the first adapter post 13 and the second adapter post 14 are arranged in an up-down crosswise layout. This can make the car charger adapter 100 more stable when performing current and voltage conversion, and minimize the area when the first adapter post 13 and the second adapter post 14 overlap, thereby avoiding electromagnetic coupling between the first adapter post 13 and the second adapter post 14.

[0066] It should be noted that the vertical cross-layout between the first adapter post 13 and the second adapter post 14 can reduce wiring in terms of structure and reduce the horizontal space occupied, which is suitable for the miniaturization and integration design requirements of the vehicle charging adapter device 100. The first cover plate 222 set on the second inner shell 22 forms an insulating gap between the first mounting groove 211 and the second mounting groove 221, which can prevent the distance between the first adapter post 13 and the second adapter post 14 from being too close, further eliminating electrical signal crosstalk or current interference, and reducing the risk of short circuit.

[0067] Furthermore, the first adapter post 13 and the second adapter post 14 are located on both sides of the second inner shell 22, the length of the first input terminal 11 is less than that of the second input terminal 12, and the length of the first output terminal 15 is greater than that of the second output terminal 16.

[0068] Understandably, with the first adapter post 13 and the second adapter post 14 located on both sides of the second inner shell 22, and respectively within the first mounting groove 211 and the second mounting groove 221, it can be seen that the first adapter post 13 and the second adapter post 14 are not placed on the same horizontal plane. By setting the length of the first input end 11 to be less than that of the second input end 12, and the length of the first output end 15 to be greater than that of the second output end 16, it can be ensured that the ends of the first input end 11 and the second input end 12, and the ends of the first output end 15 and the second output end 16 are respectively flush.

[0069] In some embodiments, the first mounting groove 211 and the second mounting groove 221, which are arranged in a cross configuration, are connected and fixed by the first cover plate 222 and the second cover plate 231, respectively, to form a stable three-dimensional support structure. This enhances the displacement resistance of the first adapter post 13 and the second adapter post 14 under conditions such as vibration and insertion / removal, thereby extending the service life of the car charger adapter device 100. In addition, placing the first adapter post 13 and the second adapter post 14 on both sides of the second inner shell 22 can also avoid spatial interference between the first electrical conduction path and the second electrical conduction path, further improving the safety and stability of using the car charger adapter device 100.

[0070] In one implementation, since the first adapter post 13 and the second adapter post 14 are located on opposite sides of the second inner shell 22, in order to ensure that the end of the first input terminal 11 away from the first adapter post 13 is flush with the end of the second input terminal 12 away from the second adapter post 14, and that the end of the first output terminal 15 away from the first adapter post 13 is flush with the end of the second output terminal 16 away from the second adapter post 14, it is necessary to set the length of the first input terminal 11 to be less than that of the second input terminal 12, and the length of the first output terminal 15 to be greater than that of the second output terminal 16, so as to ensure that the car charger adapter device 100 can work normally.

[0071] In one implementation, the end of the first input terminal 11 away from the first adapter post 13 and the end of the second input terminal 12 away from the second adapter post 14 are both cylindrical structures, and the end of the first output terminal 15 away from the first adapter post 13 and the end of the second output terminal 16 away from the second adapter post 14 are both cylindrical structures.

[0072] Please see Figure 4 and Figure 5The car charger adapter 100 also includes a housing assembly 3, which includes a first housing 31 and a second housing 32. The first housing 31 and the second housing 32 are connected back to back to form a receiving space 35, and the conductive component 1 and the inner housing assembly 2 are disposed in the receiving space 35.

[0073] In the car charger adapter 100 provided in this embodiment of the utility model, the first outer shell 31 and the second outer shell 32 in the outer shell assembly 3 are connected back to back to form an accommodating space 35, so as to facilitate the installation and fixing of the conductive component 1 and the inner shell assembly 2; at the same time, the outer shell assembly 3 has good rigid support capacity, which can provide physical protection for the conductive component 1 and the inner shell assembly 2, resist external vibration and impact, and also enhance the overall structural strength of the car charger adapter 100, adapting to harsh weather and complex environment.

[0074] Understandably, the outer shell assembly 3 and the inner shell assembly 2 work together to form a dual protection system of "external protection and internal insulation", which further isolates the conductive component 1 from the external environment, reduces the risk of leakage, fire and short circuit, and meets the safety standards of the vehicle charger adapter 100.

[0075] Furthermore, a first charging connector 33 is provided on the outer side of the first housing 31, and a second charging connector 34 is provided on the outer side of the second housing 32. The first charging connector 33 and the second charging connector 34 are respectively provided on the outer sides of the first housing 31 and the second housing 32, wherein the first charging connector 33 is used to connect to a vehicle that needs to be charged, and the second charging connector 34 is used to connect to a charging facility.

[0076] In one embodiment, the first outer shell 31 and the second outer shell 32 are detachably connected. The detachable connection methods include, but are not limited to, bolt connection, snap connection, and plug connection. In this embodiment, the detachable connection method between the first outer shell 31 and the second outer shell 32 is bolt connection, which makes the assembly and disassembly of the car charger adapter 100 more convenient and facilitates later maintenance. It can be understood that the detachable connection method between the first outer shell 31 and the second outer shell 32 can be adjusted according to actual needs. The above description is only one embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the principles of this utility model should be included within the protection scope of this utility model.

[0077] Please see Figure 4 , Figure 5 and Figure 6The first charging connector 33 includes a first DC voltage port 331 and a first auxiliary port 332. The first DC voltage port 331 includes a first DC+ port 3311 and a first DC- port 3312. The first auxiliary port 332 includes a first communication port 3321, a first ground port 3322 and a first control port 3323. The second charging connector 34 includes a second DC voltage port 341 and a second auxiliary port 342. The second DC voltage port 341 includes a second DC+ port 3411 and a second DC- port 3412. The second auxiliary port 342 includes a second control port 3421, a second ground port 3422 and a second communication port 3423.

[0078] In the vehicle charger adapter 100 provided in this embodiment of the present invention, by setting a first DC voltage port 331, a second DC voltage port 341, a first auxiliary port 332 and a second auxiliary port 342, the vehicle charger adapter 100 can conform to industry general standards and be compatible with multiple charging adapter protocols. It can transmit power and realize data interaction, further improving the compatibility of the vehicle charger adapter 100 with different standard interfaces.

[0079] Understandably, the first DC voltage port 331 and the second DC voltage port 341 serve as the main channels for transmitting electrical energy. When the first charging connector 33 of the vehicle charging adapter 100 is connected to the vehicle that needs to be charged and the second charging connector 34 is connected to the charging facility, high-voltage DC charging can be supported. The first auxiliary port 332 and the second auxiliary port 342 integrate communication, grounding and control functions, supporting functions such as charging connection confirmation and overvoltage protection during the charging process of new energy vehicles, and realizing intelligent interaction between the vehicle and the charging facility.

[0080] It should be noted that the first communication port 3321 and the second communication port 3423 can transmit voltage signals during charging and monitor the charging status. They can also dynamically adjust the charging power to optimize charging efficiency. The first grounding port 3322 and the second grounding port 3422 can provide a reliable grounding path to prevent leakage or static electricity accumulation, thereby reducing the risk of electric shock and ensuring safe and reliable charging. The first control port 3323 and the second control port 3421 can control the on / off state of the charging circuit to avoid accidental charging in the absence of connection or in abnormal state, further improving the safety of the vehicle charger adapter 100.

[0081] Please see Figures 3 to 6The ends of the first input terminal 11 and the first output terminal 15 away from the first adapter post 13 extend to the first DC+ port 3311 and the second DC+ port 3411, respectively. The ends of the second input terminal 12 and the second output terminal 16 away from the second adapter post 14 extend to the first DC- port 3312 and the second DC- port 3412, respectively. The first DC+ port 3311 is connected to the second DC+ port 3411 in sequence through the first input terminal 11, the first adapter post 13 and the first output terminal 15. The first DC- port 3312 is connected to the second DC- port 3412 in sequence through the second input terminal 12, the second adapter post 14 and the second output terminal 16.

[0082] In the car charger adapter 100 provided in this embodiment of the utility model, the first input terminal 11 and the second input terminal 12 extend to the first DC+ port 3311 and the first DC- port 3312, respectively, and the first output terminal 15 and the second output terminal 16 extend to the second DC+ port 3411 and the second DC- port 3412, respectively. The first adapter post 13 and the second adapter post 14 serve as intermediate adapter hubs, which facilitates standardized connection, shortens the current transmission distance, and improves the transmission efficiency of DC power. At the same time, combined with the design of setting insulation intervals between the first input terminal 11 and the second input terminal 12, between the first adapter post 13 and the second adapter post 14, and between the first output terminal 15 and the second output terminal 16 inside the accommodating space 35, it can achieve efficient conductivity and maintain physical and electrical isolation between positive and negative polarity ports, which meets the safety specifications of the car charger adapter 100 under high voltage DC charging, and ensures that the use of the car charger adapter 100 is more stable and reliable.

[0083] Understandably, the first DC+ port 3311 and the second DC+ port 3411 are connected through a first electrical conduction path, and the first DC- port 3312 and the second DC- port 3412 are connected through a second electrical conduction path to ensure complete separation between positive and negative polarity signals, thereby avoiding the risk of short circuits caused by path crossing or mixing. Specifically, the conductive component 1, through the sequential connection of the first input terminal 11, the first adapter post 13 and the first output terminal 15, and the sequential connection of the second input terminal 12, the second adapter post 14 and the second output terminal 16, can reduce the complex wiring of the conversion link and reduce the assembly difficulty of the internal structure of the car charger adapter device 100. The design of the input terminal and the output terminal extending directly to the port can further ensure the uniqueness of the polarity connection, thereby avoiding the error of reverse polarity connection during the assembly process.

[0084] In one implementation, when the first input terminal 11 and the second input terminal 12 extend to the first DC+ port 3311 and the first DC- port 3312 respectively, the first main sleeve 2121 and the first auxiliary sleeve 2122 both abut against the inner wall surface of the first outer shell 31. Through this design, different electrodes of the conductive component 1 can be further isolated to avoid short circuits or leakage and fire, thereby improving the safety of users charging new energy vehicles using the vehicle charging adapter 100.

[0085] Please see Figure 5 , Figure 6 and Figure 7 The accommodating space 35 is also provided with a first wire harness 351, a second wire harness 352 and a third wire harness 353; wherein, the first communication port 3321 is connected to the second communication port 3423 through the first wire harness 351, the first control port 3323 is connected to the second control port 3421 through the second wire harness 352, and the first grounding port 3322 is connected to the second grounding port 3422 through the third wire harness 353.

[0086] Understandably, the independent first wiring harness 351, second wiring harness 352, and third wiring harness 353 are respectively connected to the communication, control, and grounding ports, forming a dedicated signal transmission channel. This ensures that data interaction, connection status control, and grounding protection functions can be stably implemented during charging, avoiding signal interference or attenuation. It also facilitates the rapid docking of the communication, control, and grounding ports during production and assembly, avoiding the risk of reverse polarity or port function misalignment.

[0087] Specifically, the first communication port 3321 is connected to the second communication port 3423 via the first wiring harness 351, which can support protocol matching with the charging facility, transmit voltage signals during charging and monitor the charging status, and can also dynamically adjust the charging power to optimize charging efficiency; the first control port 3323 is connected to the second control port 3421 via the second wiring harness 352, which can control the on / off of the charging circuit to avoid accidental charging in the absence of connection or abnormal state, thereby improving charging safety; the first grounding port 3322 is connected to the second grounding port 3422 via the third wiring harness 353, which can provide a reliable grounding path to prevent leakage or static electricity accumulation, thereby reducing the risk of electric shock.

[0088] Please see Figure 4 and Figure 5The outer wall of the second housing 32 is provided with a first engaging member 321 and a second engaging member 322. The first engaging member 321 includes a first engaging end 3211 and a first button end 3212 connected together. The first engaging end 3211 is located on the side near the first charging connector 33 and corresponds to the outer wall of the first charging connector 33. The first button end 3212 is located on the outer wall of the second housing 32 near the first charging connector 33. The second engaging member 322 includes a second engaging end 3221 and a second button end 3222 connected together. The second engaging end 3221 is located inside the second charging connector 34. The second button end 3222 is located on the outer wall of the second housing 32 near the second charging connector 34.

[0089] In the vehicle charging adapter 100 provided in this embodiment of the present invention, the first charging connector 33 is connected to the charging port of the new energy vehicle that needs to be charged, and the second charging connector 34 is connected to the charging facility to support high-voltage DC charging.

[0090] Understandably, when using the vehicle charging adapter 100, the first charging connector 33 is inserted into the charging port of the new energy vehicle, and the charging gun of the charging facility is inserted into the second charging connector 34. Through the first locking end 3211 on the first locking member 321 and the second locking end 3221 on the second locking member 322, the first charging connector 33 and the second charging connector 34 can be prevented from becoming loose or falling off due to typhoons, rainstorms, or other similar situations. This strengthens the connection reliability of the first charging connector 33 and the second charging connector 34 and enhances the connection strength of the vehicle charging adapter 100.

[0091] In the embodiments of this utility model, the first locking member 321 and the second locking member 322 are tightly attached to the outer side wall of the second housing 32, which can reduce the gap between the inside of the car charger adapter 100 and the external environment, reduce the probability of dust and moisture entering the inside of the car charger adapter 100, extend the service life and adapt to various extreme weather environments.

[0092] It should be noted that the exposed design of the first button end 3212 and the second button end 3222 facilitates one-handed operation, enabling quick unlocking and plugging / unplugging between the first charging connector 33 and the new energy vehicle charging port, and between the second charging connector 34 and the charging gun, thereby improving the ease of use of the vehicle charging adapter 100.

[0093] In this embodiment of the present invention, the first locking member 321 is responsible for connecting the first charging connector 33 to the charging port of the new energy vehicle. The user's operation steps for the first button end 3212 are as follows: When connection is required, the user first presses the first button end 3212 toward one end of the second housing 32 so that the first locking end 3211 moves toward the side away from the outer wall of the first charging connector 33. Then, the first charging connector 33 is directly inserted into the charging port of the new energy vehicle. While releasing the first button end 3212, the first locking end 3211 moves toward the outer wall of the first charging connector 33. At this time, the first charging connector 33 is locked with the charging port and cannot be easily pulled out. When unlocking is required, the user only needs to press the first button end 3212 toward one end of the second housing 32 to remove the first charging connector 33 from the charging port of the new energy vehicle.

[0094] In this embodiment of the present invention, the second locking member 322 is responsible for the connection between the second charging connector 34 and the charging gun. The user's operation steps for the second button end 3222 are as follows: When connection is required, the user first presses the second button end 3222 towards one end of the second housing 32, so that the second locking end 3221 moves towards the outside of the second charging connector 34, and then directly inserts the charging gun's socket into the second charging connector 34. While releasing the second button end 3222, the second locking end 3221 moves towards the inside of the second charging connector 34. At this time, the second charging connector 34 and the charging gun's socket are locked and cannot be easily pulled out. When unlocking is required, the user only needs to press the second button end 3222 towards one end of the second housing 32 to pull the charging gun's socket out of the second charging connector 34.

[0095] Please see Figure 1 , Figure 2 and Figure 5 In some embodiments, the first input terminal 11, the first adapter post 13, the first output terminal 15, the second input terminal 12, the second adapter post 14, and the second output terminal 16 are all made of copper or copper alloy; and / or, the first latching member 321 and the second latching member 322 are both made of hard material.

[0096] The car charger adapter 100 provided in this embodiment of the present invention uses copper or copper alloy to make the first input terminal 11, the first adapter post 13, the first output terminal 15, the second input terminal 12, the second adapter post 14, and the second output terminal 16. These components have excellent conductivity, which can reduce current transmission resistance, reduce heat generation and energy loss, and facilitate current transmission. This ensures that the first input terminal 11, the first adapter post 13, the first output terminal 15, the second input terminal 12, the second adapter post 14, and the second output terminal 16 can work stably for a long time, improve charging efficiency and charging stability, and enhance the reliability of the car charger adapter 100.

[0097] It should be noted that the conductive component 1, made of copper or copper alloy, also possesses high mechanical strength and corrosion resistance. When using the car charger adapter 100, repeated plugging and unplugging are required. Copper or copper alloy has high hardness and toughness, enabling it to withstand the stress of repeated plugging and unplugging without deformation or breakage. A dense cuprous oxide film easily forms on the copper surface, preventing moisture and oxygen from further corroding the internal metal, thus avoiding increased resistance or short circuits in the conductive component 1 due to corrosion.

[0098] Understandably, the first locking component 321 and the second locking component 322, made of hard materials, have good resistance to deformation and heat resistance, so as to ensure that the locking end and the button end maintain mechanical strength during frequent insertion and removal operations, enhance connection stability, and avoid the first charging connector 33 and the second charging connector 34 from losing their quick unlocking and insertion / removal functions due to material softening or breakage, thereby extending the service life of the car charger adapter 100.

[0099] In the embodiments of this utility model, the first input terminal 11, the first adapter post 13, the first output terminal 15, the second input terminal 12, the second adapter post 14, and the second output terminal 16 are all made of copper or copper alloy, and the first locking component 321 and the second locking component 322 are both made of hard material.

[0100] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
