Wherein, referring to Figure 1 、 Figure 7 and Figure 8 , the first terminal assembly 30 and the second terminal assembly 40 are located in the shell 10.

[0077] According to one embodiment of the utility model, as shown in Figures 1-6 and Figures 8-11 , the first terminal assembly 30 comprises a first alternating current terminal assembly and a first direct current terminal assembly, and the second terminal assembly 40 comprises a second alternating current terminal assembly and a second direct current terminal assembly, wherein the first alternating current terminal assembly is electrically connected with the second alternating current terminal assembly, and the first direct current terminal assembly is electrically connected with the second direct current terminal assembly. It can be seen that, by electrically connecting the first alternating current terminal assembly with the second alternating current terminal assembly, alternating current connection between the plug of the first standard and the socket of the second standard can be realized; by electrically connecting the first direct current terminal assembly with the second direct current terminal assembly, direct current connection between the plug of the first standard and the socket of the second standard can be realized.

[0078] According to one embodiment of the utility model, as shown in Figures 1-6As shown, the first AC terminal assembly includes three-phase AC terminals 31, and the second AC terminal assembly includes single-phase AC terminals 41, wherein the single-phase AC terminals 41 are electrically connected with the three-phase AC terminals 31 through AC connection terminals 51. For example, in Figures 1-6 , the first standard is the European standard, and the second standard is the American standard, but the present application is not limited to this case.

For example, in Figures 8-11 , the first standard is the American standard, and the second standard is the European standard, but the present application is not limited to this case.

[0080] According to an embodiment of the present application, as shown in Figures 1-6 , the first AC terminal assembly further includes a first neutral terminal 32, and the second AC terminal assembly further includes a second neutral terminal 42, wherein the first neutral terminal 32 is electrically connected with the second neutral terminal 42 through a neutral connection terminal 52.

[0082] For example, through the above arrangement, in the embodiment of Figures 1-6 , taking the case that the first standard is the European standard and the second standard is the American standard, the power converter is mainly applied to adapt charging between the European standard charging pile and the American standard vehicle. The American standard vehicle can be directly charged on the European standard charging pile by using the power converter. The power converter mainly consists of AC / DC socket and AC / DC plug. As shown in Figure 2 and Figure 6 , the first terminal assembly 30 mainly consists of three-phase AC terminals 31 and a first neutral terminal 32. As shown in Figure 4 and Figure 6As shown, the second terminal assembly 40 is configured as a terminal in an AC-DC plug (European standard plug). The AC-DC plug (American standard plug) can be adapted to an American standard vehicle charging socket. The AC-DC plug is connected with the AC-DC socket to form an integrated structure. By adopting the power converter, the European standard charging pile can be adapted to the American standard vehicle, the effective charging of the American standard vehicle on the European standard charging pile is realized, and the convenience of vehicle charging of users is improved.

[0083] In some specific embodiments of the present application, with reference to Figure 6 The single-phase AC terminal 41 and the three-phase AC terminal 31 in the power converter can be electrically connected through the AC connecting terminal 51, and the first neutral terminal 32 and the second neutral terminal 42 can be electrically connected through the neutral connecting terminal 52. The terminals in the power converter are electrically connected through the corresponding connecting terminals, which eliminates the connection mode of the existing conversion device using a long wire harness structure, avoids internal wire harness arrangement disorder when there are many ports, and is inconvenient for production. In the present embodiment, each terminal is rigidly connected to the corresponding connecting terminal, which is simple in structure, low in cost, and can reduce the safety hazards caused by wire harness bending and damage.

[0084] According to one embodiment of the present application, as Figure 6 shown, the single-phase AC terminal 41, the three-phase AC terminal 31, the AC connecting terminal 51 and the neutral connecting terminal 52 are all metal terminals, the single-phase AC terminal 41 and the three-phase AC terminal 31 are welded and connected through the AC connecting terminal 51, and the first neutral terminal 32 and the second neutral terminal 42 are welded and connected through the neutral connecting terminal 52. In this way, the stability of the connection between the single-phase AC terminal 41 and the three-phase AC terminal 31 and the first neutral terminal 32 and the second neutral terminal 42 can be ensured.

[0085] In the present application, the single-phase AC terminal 41, the three-phase AC terminal 31, the AC connecting terminal 51 and the neutral connecting terminal 52 can use copper as the inner core material, the outer layer is treated with silver plating, and the corresponding terminals can be welded and connected, and the overall connection is also more stable.

[0086] According to one embodiment of the present application, as Figure 6 shown, the overlap size of the single-phase AC terminal 41 and the three-phase AC terminal 31 with the AC connecting terminal 51 is 2-10mm, and optionally, the overlap size can be 5mm. The overlap size of the first neutral terminal 32 and the second neutral terminal 42 with the neutral connecting terminal 52 is 4-6mm, and optionally, the overlap size can be 5mm. By reasonably setting the overlap width of each terminal and the corresponding connecting terminal, the stability of the connection between each terminal and the corresponding connecting terminal can be improved.

[0087] According to one embodiment of the utility model, as shown in Figure 2 and Figure 6 The first DC terminal assembly includes a first DC positive terminal 33 and a first DC negative terminal 34. Figure 4 and Figure 6 The second DC terminal assembly includes a second DC positive terminal 43 and a second DC negative terminal 44, and the first DC positive terminal 33 is electrically connected to the second DC positive terminal 43 through a DC positive connection terminal 53, and the first DC negative terminal 34 is electrically connected to the second DC negative terminal 44 through a DC negative connection terminal 54. The first DC positive terminal 33 and the first DC negative terminal 34 are used to provide a first standard, such as a European standard, DC current, and the second DC positive terminal 43 and the second DC negative terminal 44 are used to provide a second standard, such as an American standard, DC current, realizing a DC charging mode of the vehicle. By arranging the first DC positive terminal 33 and the first DC negative terminal 34 in a European standard socket and arranging the second DC positive terminal 43 and the second DC negative terminal 44 in an American standard plug, the DC charging mode is increased, ensuring that the power converter can simultaneously have AC conversion and DC conversion capabilities, and increasing the application scenarios of the power converter.

[0088] Therefore, according to the power converter of the embodiment, the AC socket for connecting the European standard charging pile plug and the AC plug for connecting the American standard vehicle charging socket are integrated, and the European standard charging pile can be effectively used to charge the American standard vehicle. Meanwhile, the power converter is provided with the single-phase AC terminal 41, the three-phase AC terminal 31, the first neutral terminal 32, the second neutral terminal 42, the first DC positive terminal 33, the first DC negative terminal 34, the second DC positive terminal 43, and the second DC negative terminal 44, which can not only meet the AC charging mode of the European standard to the American standard, but also simultaneously have the DC charging mode, increasing the application scenarios of the power converter.

[0089] As can be seen from the above, Figures 1-6 some embodiments of the utility model provide a power converter for converting a first standard, such as a European standard vehicle charging interface, into a second standard, such as an American standard automobile charging interface. When charging the American standard electric vehicle, the converted charging socket (for example, a European standard socket) is first connected to the European standard charging pile plug, and then the converted charging plug (for example, an American standard plug) is inserted into the charging socket of the American standard electric vehicle to realize charging without additional operations, so that the American standard vehicle and the European standard charging pile have a better application range, and the application of the portable product is conducive to the popularization and application of electric vehicles.

[0090] According to one embodiment of the utility model, as shown in Figures 7 to 11As shown, the first DC terminal assembly includes a first DC positive terminal 33 and a first DC negative terminal 34, and the second DC terminal assembly includes a second DC positive terminal 43 and a second DC negative terminal 44. The first DC positive terminal 33 is connected with the second DC positive terminal 43, for example, electrically connected through a DC positive connection terminal 53. The first DC negative terminal 34 is connected with the second DC negative terminal 44, for example, electrically connected through a DC negative connection terminal 54. The power converter of this embodiment is mainly applied to the adaptive charging between a first standard, for example, a US standard charging pile, and a second standard, for example, a European standard vehicle, so that the European standard vehicle can be directly charged on the US standard charging pile by using the power converter. The power converter in this embodiment mainly consists of an AC / DC socket and an AC / DC plug. Among them, the first terminal assembly 30 is configured as the terminal in the AC / DC socket (US standard socket) which can adapt to the US standard charging pile plug, such as Figure 8 and Figure 9 As shown, the first terminal assembly 30 mainly consists of a single-phase AC terminal 211, a first neutral terminal 32, a first DC positive terminal 33 and a first DC negative terminal 34. As shown in Figure 8 and Figure 10 The second terminal assembly 40 is configured as the terminal in the AC / DC plug (European standard plug). The AC / DC plug (European standard plug) can adapt to the European standard vehicle charging socket. The AC / DC plug is connected with the AC / DC socket to form an integrated structure. By using the power converter of this embodiment, the US standard charging pile can be adapted to the European standard vehicle, the effective charging of the European standard vehicle on the US standard charging pile can be realized, and the convenience of vehicle charging for users can be improved.

[0091] Therefore, in Figures 7-11In this embodiment, taking the first standard as the US standard and the second standard as the European standard as an example, the housing 10 and the first terminal assembly 30 constitute an AC / DC socket (e.g., a US standard socket), and the housing 10 and the second terminal assembly 40 constitute an AC / DC plug (e.g., a European standard plug). The AC / DC plug mainly consists of a three-phase AC terminal 411, a second neutral terminal 42, a second DC positive terminal 43, and a second DC negative terminal 44. The single-phase AC terminal 211 (US standard live wire L) is connected to the three-phase AC terminal 411 (European standard live wire N), and the first neutral terminal 32 (US standard neutral wire L) is connected to the second neutral terminal 42 (European standard neutral wire N). The single-phase AC terminal 211 and the first neutral terminal 32 are used to provide AC current according to the US standard, and the three-phase AC terminal 411 and the second neutral terminal 42 are used to provide AC current according to the European standard, realizing the AC charging mode of the vehicle. The first DC positive terminal 33 is connected to the second DC positive terminal 43, and the first DC negative terminal 34 is connected to the second DC negative terminal 44. The first DC positive terminal 33 and the first DC negative terminal 34 are used to provide DC current to the US standard terminal, and the second DC positive terminal 43 and the second DC negative terminal 44 are used to provide DC current to the European standard terminal, thereby realizing the DC charging mode of the vehicle.
