[0030] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the drawings.
[0031] As Figures 1-5 As shown in the utility model discloses a kind of charging systems, including charging gun 100 and with the charging gun 100 and plug-in charging socket 200, the charging gun 100 includes multiple first power terminal 13, first passage 131 is equipped in the first power terminal 13, cooling medium is communicated in the first passage 131;The charging socket 200 includes shell 21 and multiple second power terminal 22 in the shell 21, second passage 221 is equipped in the second power terminal 22, the second passage 221 with the shell 21 outside communication;Wherein, when the charging gun 100 and the charging socket 200 are plugged, the first power terminal 13 and the second power terminal 22 are plugged, the first passage 131 and the second passage 221 are communicated, the cooling medium flows through the first passage 131, second passage 221 in turn, and is discharged to the outside of the shell 21.
[0032] It can be understood that the charging system comprises a charging gun 100 and a charging socket 200, one end of the charging gun 100 is plugged into the charging socket 200, and the other end of the charging gun 100 is connected to a charging device such as a charging pile through a cable 14. The charging gun 100 is provided with a plurality of first power terminals 13, the first power terminals 13 are electrically connected to the charging device such as the charging pile through wires in the cable 14, so that electric energy is transmitted from the charging device such as the charging pile to the first power terminals 13. The charging socket 200 is installed on a new energy vehicle, and the charging socket 200 comprises a housing 21 and a plurality of second power terminals 22 arranged in the housing 21. The second power terminals 22 are electrically connected to other devices in the new energy vehicle, such as a battery and the like. When the charging gun 100 is plugged into the charging socket 200, the plurality of first power terminals 13 are respectively plugged into the plurality of second power terminals 22 to achieve electric energy transmission, the electric energy can be transmitted from the charging device such as the charging pile to the charging gun 100, and then transmitted from the charging socket 200 to the battery in the new energy vehicle to achieve charging of the new energy vehicle. When the first power terminals 13 and the second power terminals 22 are plugged in for electric energy transmission, a large amount of heat is generated on the first power terminals 13 and the second power terminals 22. A refrigeration device can also be arranged in the charging device, a first passage 131 is arranged in the first power terminal 13, and a second passage 221 is arranged in the second power terminal 22, and the second passage 221 is in communication with the outside of the housing 21. In this way, when the first power terminals 13 and the second power terminals 22 are plugged in, the cooling medium in the refrigeration device can flow into the first passage 131 in the plurality of first power terminals 13, and since the first passage 131 is in communication with the second passage 221, the cooling medium in the first passage 131 can further flow into the second passage 221, thereby absorbing the heat on the first power terminals 13 and the second power terminals 22 to cool the first power terminals 13 and the second power terminals 22. The heated cooling medium can be discharged out of the housing 21 of the charging socket 200 and will not be recycled, thereby improving the cooling efficiency, ensuring the cooling effect, and simplifying the cooling process.
[0033] Further, in an embodiment of the utility model, the first main pipeline is arranged in the charging gun 100, one end of the first main pipeline is in communication with the plurality of first passages 131, and the other end of the first main pipeline is in communication with the refrigeration device.
[0034] It can be understood that one end of the first main pipeline is in communication with the first passage 131 of each first power terminal 13, and the other end of the first main pipeline is in communication with the refrigeration device. The cooling medium in the refrigeration device flows into the first main pipeline and then flows into each first passage 131 from the first main pipeline to cool each first power terminal 13.
[0035] Further, in an embodiment of the utility model, the charging socket 200 is further provided with a second main pipeline 214, one end of the second main pipeline 214 is communicated with a plurality of second passages 221, and the other end of the second main pipeline 214 is communicated with the outside of the shell 21.
[0036] It can be understood that the second main pipeline 214 is provided with a passage 215 for the cooling medium to flow. One end of the second main pipeline 214 is communicated with the second passage 221 of each second power terminal 22, and the other end of the second main pipeline 214 is communicated with the outside of the shell 21. Since the first power terminal 13 and the second power terminal 22 are plugged, the first passage 131 and the second passage 221 are communicated, and thus the cooling medium flowing into each first passage 131 flows into the second passage 221 communicated therewith respectively, so as to further cool each second power terminal 22. The cooling medium flowing out of the second passage 221 has its temperature increased due to absorbing the heat of the first power terminal 13 and the second power terminal 22. The temperature-increased cooling medium flows into the second main pipeline 214 and is discharged from the end of the second main pipeline 214 away from the second power terminal 22 to the charging socket 200.
[0037] Further, in an embodiment of the utility model, the shell 21 comprises a mounting plate 211, a plugging part 212 and a tail part 213 connected to two ends of the mounting plate 211 respectively, the plugging part 212 is used for plugging with the charging gun 100, and the tail part 213 has a side wall 2131 in a cylindrical shape, one end of the second main pipeline 214 away from the second power terminal 22 penetrates through the side wall 2131, so as to be communicated with the outside of the shell 21.
[0038] It can be understood that, as Figures 3-4As shown, the shell 21 comprises a mounting plate 211, which is used to mount the charging socket 200, for example, the charging socket 200 can be mounted on the new energy vehicle through the mounting plate 211. Preferably, the mounting plate 211 can be provided with mounting holes, and the mounting plate 211 and the new energy vehicle are fixedly mounted by fasteners passing through the mounting holes and the fixing holes on the new energy vehicle. In order to realize the maintenance and replacement of the charging socket 200, the mounting plate 211 can be detachably mounted on the new energy vehicle. One end of the mounting plate 211 is provided with a plug-in part 212, and the second power terminal 22 is arranged in the plug-in part 212. The plug-in part 212 is used to plug with the gun head 11 of the charging gun 100. The end of the shell 21 away from the mounting plate 211 is a tail part 213. The end of the second power terminal 22 close to the tail part 213 is led out through the wires for power and / or control signals and the like. The tail part 213 is provided with a via hole for facilitating the wires to pass through. When the charging socket 200 is mounted on the new energy vehicle, the plug-in part 212 is exposed outside the new energy vehicle to facilitate the plug-in of the gun head 11, and the tail part 213 is contained in the new energy vehicle to facilitate the wires to be led out from the tail part 213 to various devices.
[0039] The tail part 213 has a side wall 2131 in a cylindrical shape, and the side wall 2131 forms a cavity inside to facilitate the accommodation of various wires, circuit boards and the like. The second main pipeline 214 passes through the side wall 2131 at the end away from the second power terminal 22 to communicate with the outside of the shell 21. In this way, the cooling medium can be directly discharged from the side wall 2131 to the outside of the charging socket 200. Preferably, the cooling medium is a gas. Preferably, the second main pipeline 214 passes through the bottom of the side wall 2131. By passing through the bottom of the side wall 2131 through the second main pipeline 214, the cooling medium can be discharged from the bottom of the tail part 213, and the discharged cooling medium will not immediately move due to the action of gravity and will not adhere to the shell 21 of the charging socket 200.
[0040] Further, in an embodiment of the utility model, the first power terminal 13 is a pin, and the second power terminal 22 is a jack. Preferably, the first passage 131 extends along the axis of the first power terminal 13, and the second passage 221 extends along the axis of the second power terminal 22. When the first power terminal 13 and the second power terminal 22 are plugged, the axes of the first passage 131 and the second passage 221 are on the same line, facilitating the flow of the cooling medium. It can be understood that the end of the first power terminal 13 close to the first main pipeline can be connected to the first main pipeline through a pipeline, or connected to the first main pipeline through an adapter or the like, and of course it can also be directly connected to the first main pipeline, which is not limited here. The end of the second power terminal 22 close to the second main pipeline 214 can be connected to the second main pipeline 214 through a pipeline, and of course it can also be connected to the second main pipeline 214 through an adapter or the like, and of course it can also be directly connected to the second main pipeline 214, which is not limited here.

Corresponding to the first power terminal 13, the number of the second power terminal 22 is also four.
[0042] It can be understood that the charging gun 100 can be a charging gun 100 of multiple models. For example, when the charging gun 100 is a three-phase alternating current charging gun 100, the charging gun 100 has three first power terminals 13 connected to live lines and one first power terminal 13 connected to a neutral line. The number of the second power terminal 22 corresponding to the three-phase alternating current charging gun 100 is also four, and the four second power terminals 22 are respectively plugged with the four first power terminals 13.
[0043] Further, in an embodiment of the utility model, the charging gun 100 further comprises a cable 14, and the cable 14 is provided with the first main pipeline.
[0044] It can be understood that, as Figures 1-2As shown, the charging gun 100 has a gun head 11 and a gun body 12, and the end of the gun body 12 away from the gun head 11 is also provided with a cable 14, and the other end of the cable 14 is connected to a charging device such as a charging pile. The cable 14 is provided with wires and the like. Of course, the cable 14 is also provided with a first main pipeline. One end of the first main pipeline is connected to the refrigeration device to deliver the cooling medium to each first passage 131. The cooling medium in the first passage 131 further flows into the second passage 221 to cool the first power terminal 13 and the second power terminal 22. The warmed cooling medium flows into the second main pipeline 214 and is discharged from the other end of the second main pipeline 214 to the charging socket 200. After the cooling medium absorbs the heat on the first power terminal 13 and the second power terminal 22, it is directly discharged from the charging socket 200 and will not be recycled, thereby improving the cooling efficiency, ensuring the cooling effect, and simplifying the cooling process.
