A card block 302 is installed on the sealing plate 301, and a plurality of pairs of card slots 3021 are opened inside the socket shell 201. The card block 302 and the card slot 3021 correspond to each other. When the charging gun socket body 1011 and the socket body 203 are plugged into each other, the operator first rotates the sealing plate 301 to separate the sealing plate 301 from the end face of the charging gun socket body 1011, and as the charging gun socket body 1011 and the socket body 203 are plugged into each other, the operator first rotates the sealing plate 301 to separate the sealing plate 301 from the end face of the charging gun socket body 1011, and as the charging gun socket body 1011 and the plug The socket bodies 203 are plugged into each other, and the sealing plate 301 is rotated to an inclined state. The block 302 on the sealing plate 301 can be snapped into the slot 3021 at this time. In this way, after the end face of the charging gun socket body 1011 is opened, the sealing plate 301 is in a positioned state, will not scratch the paint surface, and is safer to operate. The rotated sealing plate 301 and the block 302 can be snapped into the slot 3021, thereby limiting the charging gun socket body 1011 as a whole and achieving a fixing effect. Therefore, a single sealing plate 301 can have multiple effects, a more ingenious structure, and more convenient operation.

During the rotation of the sealing plate 301, the rocker 4041 and the swing arm 4042 are squeezed to deflect, and the swing arm 4042 pushes the top block 401 to move outward. After the sealing plate 301 rotates, the sealing plate 301 can drive the seesaw 4041 to rotate. The seesaw 4041 drives the top block 401 at the end to slide outward through the swing arm 4042. The top block 401 can be squeezed with the inside of the socket socket body 203, thereby assisting the separation of the socket socket body 203 and the charging gun socket body 1011, making it convenient for the operator to disassemble the plug assembly 100 and the socket assembly 200 from each other, making the operation more convenient.

The pressure plate 3042 can squeeze the extrusion spring 3043 at this time, and the extrusion spring 3043 is used to facilitate the reset operation later. During the movement of the extrusion rod 3041, the synchronization plate 3044 drives the plug plate 305 to slide as a whole.

[0032] Embodiment 3, based on the above embodiment and the difference between this embodiment and the present embodiment is: Figure 8 and Fig. 9As shown, a limiting groove 4011 is provided inside the charging gun socket body 1011, and a through groove 4012 is provided on the side wall of the limiting groove 4011. The limiting groove 4011 is slidably connected to the top block 401, and a slide plate 4022 is installed at the bottom of the top block 401. The slide plate 4022 is slidably set on the slide groove 402 provided at the bottom of the limiting groove 4011, and a positioning rod 4021 is installed on the side wall of the slide groove 402. Both ends of the positioning rod 4021 are respectively connected to the slide groove 402, and a positioning spring 4023 is sleeved on the positioning rod 4021. One end of the positioning spring 4023 is clamped on the end face of the slide groove 402, and the other end is clamped on the slide plate 4022. During the sliding of the top block 401, the slide plate 4022 at the bottom of the top block 401 slides in the slide groove 402, and the slide plate 4022 moves along the direction of the positioning rod 4021. During the movement, the positioning spring 4023 can be compressed, and the positioning spring 4023 is used to facilitate subsequent resetting.

[0033] like Figure 8 and Fig. 9 As shown, further, a positioning shaft 404 is rotatably installed on the through slot 4012, the positioning shaft 404 and the rotation centers of the rocker 4041 are connected to each other, the other end of the positioning shaft 404 is connected to the rotation center of the swing arm 4042, a strip groove 4043 is opened on the swing arm 4042, a protrusion 4032 is slidably arranged on the strip groove 4043, the protrusion 4032 is connected to the side rod 4031, and a connecting block 403 is installed at the end of the side rod 4031, and the end of the connecting block 403 is connected to the end face of the top block 401. During the upward rotation of the sealing plate 301, the seesaw 4041 is subjected to an extrusion force, and then the seesaw 4041 drives the positioning shaft 404 to rotate, and the positioning shaft 404 drives the swing arm 4042 to rotate, and a protrusion 4032 is slidingly provided on the strip groove 4043 inside the swing arm 4042. At this time, the protrusion 4032 is squeezed and moved outward, and the protrusion 4032 drives the side rod 4031 and the connecting block 403 to move, and the connecting block 403 drives the top block 401 to slide outward along the limiting groove 4011, and the top block 401 can squeeze the inside of the socket socket body 203, thereby assisting the separation of the socket socket body 203 and the charging gun socket body 1011.

[0034] The implementation principle of a new energy vehicle charging connection device of this embodiment is as follows: When the charging gun socket body 1011 and the socket socket body 203 need to be plugged into each other, the operator first rotates the sealing plate 301. At this time, the sealing plate 301 needs to be rotated out of the mounting groove 3011 so that the end face of the charging gun socket body 1011 can be opened. When the sealing plate 301 rotates, the sealing plate 301 drives the rotating shaft 3012 to rotate inside the mounting seat 3014, and then the torsion spring 3013 on the mounting seat 3014 is twisted synchronously, and the torsion spring 3013 is used to facilitate the later reset operation, and finally the charging gun socket body 1011 becomes Figure 3 state, at which time the sealing plate 301 is located below the charging gun socket body 1011.

[0035] Then, the charging gun socket body 1011 and the socket socket body 203 are plugged into each other. When plugged into the specified position, the current position is limited by the magnetic block 103, and the blocking block 1012 is used to limit the two so that the two will not be plugged too deep. At this time, the sealing plate 301 will also slide into the socket shell 201 synchronously. At this time, the torsion spring 3013 will drive the sealing plate 301 to rotate in the opposite direction, and the sealing plate 301 will drive the surface block 302 to rotate downward. At this time, the block 302 can be plugged into the card slot 3021, and finally the charging gun socket body 1011 and the socket socket body 203 can be locked to ensure that the charging gun socket body 1011 and the socket socket body 203 cannot be separated.

[0036] In this way, it is ensured that after the end face of the charging gun socket body 1011 is opened, the sealing plate 301 is in a positioned locked state, will not scratch the paint surface, and is safer to operate. The rotated sealing plate 301 and the card block 302 can be engaged in the card slot 3021, thereby limiting the charging gun socket body 1011 as a whole and achieving a fixing effect. Therefore, a single sealing plate 301 can have multiple effects, with a more ingenious structure and more convenient operation.

[0037] And after the connection is completed, the compression spring 1023 pushes the baffle 1022 and the protective plate 1021 to slide, and the baffle 1022 drives the protective plate 1021 to move outward until it moves to the end face of the socket shell 201 and stops. At this time, the protective plate 1021 mainly protects the charging position, and the internal protective rod 1024 mainly plays a limiting role, positioning the moving direction of the protective plate 1021.

[0038] When unlocking is needed later, the operator can press the button 3045, and the button 3045 drives the bottom extrusion rod 3041 to slide into the extrusion cover 304, and the pressure plate 3042 inside the extrusion cover 304 slides synchronously, and the pressure plate 3042 can squeeze the extrusion spring 3043 at this time, and the extrusion spring 3043 facilitates the reset operation later, and during the movement of the extrusion rod 3041, the synchronous plate 3044 drives the plug plate 305 to slide as a whole, and the plug plate 305 drives this When the plug rod 3051 slides, the sliding bar 3052 on the plug rod 3051 slides in the guide groove 3053.
