[0030] Reference is made to Figures 2-5The utility model discloses a direct current charging module 1, including direct current casing 11, direct current charging terminal 12 and conductive adapter structure 13, direct current charging terminal 12 sets up in direct current casing 11, direct current casing 11 is provided with lateral wire port 1122, the axial direction of lateral wire port 1122 is perpendicular with the axial direction of direct current charging terminal 12, conductive adapter structure 13 is located in direct current casing 11, and one end of conductive adapter structure 13 is connected with direct current charging terminal 12, and at least part of conductive adapter structure 13 is opposite to lateral wire port 1122.

[0031] The direct current charging module 1 can be applied to a direct current fast charging type charging socket or a direct current alternating current combined type charging socket.

[0032] Specifically, when the charging socket with the direct current charging module 1 is arranged between the front fender and the front side wall connecting plate assembly, the direct current charging terminal 12 in the direct current casing 11 extends along the transverse direction of the vehicle. With the conductive adapter structure 13 in the direct current casing 11 and the lateral wire port 1122 of the direct current casing 11, one end of the thick wire 71 for direct current fast charging can directly enter the direct current casing 11 through the lateral wire port 1122 without bending, and the thick wire 71 entering the direct current casing 11 through the lateral wire port 1122 can be directly connected with the conductive adapter structure 13 without turning in the direct current casing 11, the thick wire 71 is electrically connected with the direct current charging terminal 12 through the conductive adapter structure 13, and the other end of the thick wire 71 can directly extend forward along the space between the front fender and the front side wall connecting plate assembly and then enter the cabin to be connected with the direct current exchange machine, high-low converter and other electrical devices in the cabin.

[0033] In the embodiment, the thick wire 71 for direct current fast charging does not need to be bent and routed between the direct current charging terminal 12 and the front side wall connecting plate assembly, which ensures that the charging socket with the direct current charging module 1 can be arranged and connected with the thick wire 71 in the narrow space between the front fender and the front side wall connecting plate assembly, and meets the needs of users for different charging positions.

[0034] It should be noted that when the automobile is directly charged, a DC switch and a high-low voltage converter are usually needed, and when the charging socket with the DC charging module 1 is arranged between the front wing panel and the front side wall connecting plate assembly, the DC switch and the high-low voltage converter of the automobile are generally arranged inside the engine compartment close to the charging socket. Therefore, the first end of the thick wire 71 enters the DC shell 11 in a direction perpendicular to the axial direction of the DC charging terminal 12 (the X-axis direction shown in the figure), and then the thick wire 71 can be indirectly connected to the DC charging terminal 12 through the conductive adapter structure 13, without the need to bend the first end of the thick wire 71, and the second end of the thick wire 71 can extend in the X-axis direction for a distance and then bend into the engine compartment to be connected to the DC switch, the high-low voltage converter and other electrical devices.

[0035] Of course, in other embodiments, the charging socket with the DC charging module 1 can also be arranged at the rear wheel cover of the automobile, and at this time, the DC switch and the high-low voltage converter of the automobile are generally arranged on the lower side of the trunk close to the charging socket. At this time, the lateral wire passing port 1122 of the DC shell 11 can be located on the lower side of the DC shell 11, the first end of the thick wire 71 enters the DC shell 11 through the lateral wire passing port 1122 in the vertical direction and is connected to the conductive adapter structure 13, and the second end of the thick wire 71 extends downward and then bends into the lower side of the trunk to be connected to the DC switch, the high-low voltage converter and other structures.

[0036] In order to facilitate understanding and avoid confusion, hereinafter, the charging socket with the DC charging module 1 is exemplarily illustrated as being arranged between the front wing panel and the front side wall connecting plate assembly.

[0037] Optionally, referring to Figure 4 , the conductive adapter structure 13 includes an adapter sheet 131, the thickness direction of the adapter sheet 131 is perpendicular to the axial direction of the DC charging terminal 12, and the adapter sheet 131 is connected to one end of the DC charging terminal 12.

[0038] In this embodiment, the adapter piece 131 is a metal piece with electric conductivity, and the thickness direction of the adapter piece 131 is parallel to the axial direction of the DC charging terminal 12. In this way, the adapter piece 131 can have a larger area to contact and connect with the DC charging terminal 12. The "at least part of the electrically-conductive adapter structure 13 is arranged opposite to the lateral wire passing port 1122" refers to that one end of the adapter piece 131 in the longitudinal direction of the vehicle is arranged opposite to the lateral wire passing port 1122. In this way, the first end of the thick wire 71 can have the surface insulation layer stripped to expose all the copper wires of the first end. After the first end of the thick wire 71 enters the DC housing 11 through the lateral wire passing port 1122, all the exposed copper wires of the first end of the thick wire 71 can be directly attached to the two surfaces of the adapter piece 131 in the thickness direction, and then all the copper wires of the first end of the thick wire 71 can be welded and fixed to the adapter piece 131 by ultrasonic welding.

[0039] In addition, since the thickness direction of the adapter piece 131 is parallel to the axial direction of the DC charging terminal 12, both are parallel to the lateral direction of the vehicle. This not only ensures that the adapter piece 131 has a larger contact area and connection area with one end of the DC terminal (the end close to the vehicle interior), but also ensures that the copper wires of the first end of the thick wire 71 can be directly attached to the adapter piece 131 without bending, and the copper wires have a larger contact area with the adapter piece 131, which is convenient for ultrasonic welding and has a sufficient welding area. In addition, the adapter piece 131 is relatively thin, which hardly occupies additional lateral space of the vehicle, ensuring that the DC charging module 1 and the part close to the first end of the thick wire 71 can be arranged between the front fender and the front side wall assembly.

[0040] Optionally, referring to Figure 4 , the electrically-conductive adapter structure 13 further comprises a first fastener 132, and the adapter piece 131 is provided with a piece hole, and the first fastener 132 is used to be inserted into the piece hole and connected into the DC charging terminal 12 to connect and fix the adapter piece 131 and one end of the DC charging terminal 12.

[0041] In this embodiment, the electrically-conductive adapter structure 13 comprises the adapter piece 131 and the first fastener 132. After the adapter piece 131 is attached to the end surface of the DC charging terminal 12, the adapter piece 131 can be connected and fixed to the DC charging terminal 12 by the first fastener 132. The first fastener 132 can be a screw, a bolt or the like, which not only facilitates the connection and fixation of the adapter piece 131 and the DC charging terminal 12, but also can play an electrically-conductive role since the first fastener 132 is also a metal piece.

[0042] Optionally, referring to Figures 2-4, the direct current shell 11 includes a direct current insulation shell 111, a direct current diversion shell 112 and a tail cover 113 connected in sequence; the direct current charging terminal 12 is located in the direct current insulation shell 111 in at least part of the axial direction thereof, the direct current diversion shell 112 includes a main cavity and a lateral wire passing cavity 1121 arranged protruding relative to the main cavity, and the conductive adapter structure 13 is located in the main cavity of the direct current diversion shell 112; the extension direction of the lateral wire passing cavity 1121 is perpendicular to the axial direction of the direct current charging terminal 12, and one end of the lateral wire passing cavity 1121 is open as the lateral wire passing opening 1122.

[0043] In the embodiment, the direct current shell 11 is a split assembly to facilitate the installation of the internal structure, and the direct current shell 11 can be roughly regarded as a cylindrical structure, which specifically includes the direct current insulation shell 111, the direct current diversion shell 112 and the tail cover 113 connected in sequence along the axial direction thereof. The direct current insulation shell 111 is mainly used for internally installing the direct current charging terminal 12, and the direct current insulation shell 111 and the direct current diversion shell 112 are both provided with an open end. When the direct current charging module 1 is assembled, the following steps can be performed: step one, the direct current charging terminal 12 is first installed into the direct current insulation shell 111 along the axial direction of the direct current insulation shell 111; step two, the conductive adapter structure 13 is connected to one end of the direct current charging terminal 12; step three, the open end (the head end is open) of the direct current diversion shell 112 is connected and fixed to the open end (the tail end is open) of the direct current insulation shell 111 in a butt joint manner, and the conductive adapter structure 13 is located in the direct current diversion shell 112; step four, the first end of the thick wire 71 enters the lateral wire passing cavity 1121 of the direct current diversion shell 112 through the lateral wire passing opening 1122, and then enters the main cavity of the direct current diversion shell 112; step five, all the copper wires exposed at the first end of the thick wire 71 are attached to the adapter sheet 131, and then the copper wires at the first end of the thick wire 71 are welded to the adapter sheet 131 by ultrasonic welding in the operation space provided by the open end (that is, the tail end opening of the direct current diversion shell 112) of the direct current diversion shell 112 away from the direct current insulation shell 111 in the transverse direction; and step six, the tail cover 113 is arranged at the tail end opening of the direct current diversion shell 112 to achieve sealing.

[0045] In order to ensure safety during DC fast charging, the DC charging module 1 is generally required to be connected with a grounding wire 73, and the grounding wire 73 is not thick, so that the end of the grounding wire 73 close to the DC fast charging module can be bent and routed. In the embodiment, as shown in Figure 5 , a plurality of binding cooperation structures 1131 are arranged at the tail part of the DC shell 11 (the part close to the inside of the vehicle in the lateral direction of the DC shell 11), for example, two binding cooperation structures 1131 are arranged on the tail cover 113, and the arrangement direction of the two binding cooperation structures 1131 is parallel to the axial direction of the lateral wire passing port 1122, as shown in Figure 5 , the end of the grounding wire 73 close to the DC charging module 1 is bent, and then the grounding wire 73 can be fixed at the two binding cooperation structures 1131 arranged in sequence by means of a cable tie, so that the grounding wire 73 can enter the cabin together with the thick wire 71.
