[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figure 1-Figure 5 The present invention provides a charging device for a new energy vehicle, comprising: Charging station 1; A cable reel 2 is provided on the charging pile 1; A charging cable 3 is arranged on the cable winding device 2, and the charging cable 3 is connected to the charging pile 1; A first assembly cylinder 4 is fixedly connected to the charging cable 3.

[0021] The first assembly tube 4 and the second assembly tube 6 are connected and fixed by the assembly mechanism, so that the first conductive block 5 is in contact with the second conductive block 7, and electrical conduction is achieved between the charging cable 3 and the charging gun 8. During the charging process, when the temperature of the charging gun 8 reaches a certain level, the memory telescopic mechanism deforms to push the elastic mechanism, thereby separating the second conductive block 7 from the first conductive block 5, and implementing power-off measures. When the temperature of the charging gun 8 drops to a certain temperature, the memory telescopic mechanism resets and pulls the elastic mechanism, so that the second conductive block 7 and the first conductive block 5 are re-fitted, so that the second conductive block 7 and the first conductive block 5 are restored to electrical conduction, and an automatic on-off effect is achieved, thereby avoiding the charging gun 8 from working at a continuous high temperature, and effectively preventing the charging gun 8 from causing fire and other safety hazards due to overheating.

[0022] The cable reeling device 2 is an automatic telescopic locking device, which is a prior art and will not be described in detail here.

[0024] By rotating the connecting sleeve 9 and cooperating with the first assembly sleeve 4 through the thread, the connecting sleeve 9 is rotated and moved in the first assembly sleeve 4, so that the connecting sleeve 9 is screwed into the locking sleeve 10 through the thread, thereby realizing the connection and fixation between the first assembly sleeve 4 and the second assembly sleeve 6.

[0025] In one embodiment of the present invention, a plurality of plug posts 11 are circumferentially fixedly connected to one end of the first assembly cylinder 4 close to the second assembly cylinder 6, and a plurality of slots 12 are circumferentially opened to one end of the second assembly cylinder 6 close to the first assembly cylinder 4. The plurality of plug posts 11 correspond one-to-one to the plurality of slots 12 and can be detachably plugged in.

[0026] The first assembly tube 4 and the second assembly tube 6 are pre-fixed by inserting the plug 11 into the slot 12 .

[0030] After the first assembly cylinder 4 and the second assembly cylinder 6 are locked and fixed, the adjusting head 22 is rotated to make the adjusting rod 13 rotate and move along the threaded sleeve 21 through the thread, thereby pushing the first connecting plate 14 to move, and pushing the second connecting plate 16 to move through the elastic member 17, thereby driving the first conductive block 5 to slide along the guide groove 19, so that the first conductive block 5 contacts the second conductive block 7, and the threaded cooperation of the adjusting rod 13 and the threaded sleeve 21 can limit the position of the first connecting plate 14, so that when the memory telescopic mechanism pushes the second connecting plate 16, the first conductive block 5 is pushed to move, and the elastic member 17 is compressed at the same time, and vice versa, the elastic member 17 pushes the first conductive block 5 to reset.
