[0027] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0028] Embodiment 1: Refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 , a new energy vehicle connector includes a socket 1 and a plug 102, and further includes: a first fixing plate 101 fixedly connected to the socket 1; a second fixing plate 103 fixedly connected to the plug 102. Among them, a fixed groove 305 is formed on the second fixing plate 103, and an inserting rod 3 is fixedly connected to the first fixing plate 101, and the inserting rod 3 is inserted into the fixed groove 305; a clamping component connected to the inserting rod 3, and when the inserting rod 3 is inserted into the fixed groove 305, the clamping component is used to limit and fix the inserting rod 3; a sealing unit respectively connected to the socket 1 and the plug 102; an airbag 607 disposed around the inner wall of the socket 1. Among them, a second sealing groove 608 is formed on the sealing unit, and an air supply component is provided on the socket 1. When the plug 102 is docked with the socket 1, the air supply component extracts external gas and conveys it to the airbag 607, and the airbag 607 expands and fits with the second sealing groove 608.

[0029] The clamping component includes a fixed block 303 and a first spring 304. A first groove 301 is formed on the inserting rod 3, a sealing plate 302 is slidably connected in the first groove 301, the fixed block 303 is fixedly connected to the sealing plate 302, the first spring 304 is fixedly connected between the sealing plate 302 and the inner wall of the first groove 301, and the fixed block 303 is clamped on the side wall surface of the second fixing plate 103.

[0030] The sealing unit includes a plug-in frame 4 and a connecting frame 402. The connecting frame 402 is fixedly connected to the inner wall of the socket 1. A first sealing groove 403 is formed between the connecting frame 402 and the inner wall of the socket 1. The plug-in frame 4 is inserted into the first sealing groove 403. A sealing gasket 401 is fixedly connected to the outer side wall of the plug-in frame 4, and the sealing gasket 401 is in contact with the inner wall of the socket 1.

[0031] A conduit 7 is fixedly communicated with the airbag 607, and a valve switch 701 is provided on the conduit 7.

[0032] Guide rods 5 are symmetrically and fixedly connected to the inner wall of the plug 102, and sliding seats 501 are symmetrically and fixedly connected to the inner wall of the socket 1. The guide rods 5 are slidably connected to the sliding seats 501.

[0033] Fixing seats 8 are symmetrically and fixedly connected to the inner wall of the socket 1. A second groove 801, a third groove 802, and a hollow cavity 805 are formed in the fixing seats 8. The guide rods 5 are inserted into the second groove 801. A self-locking block 804 is slidably connected to the third groove 802. A third spring 803 is fixedly connected between the self-locking block 804 and the inner wall of the third groove 802. A limiting groove 809 is formed in the side wall of the guide rod 5, and the self-locking block 804 is inserted into the limiting groove 809. A slider 806 is slidably connected to the hollow cavity 805. The slider 806 is fixedly connected to the self-locking block 804 through a pull rod 807. A third pipeline 808 is fixedly communicated with the hollow cavity 805, and one end of the third pipeline 808 away from the hollow cavity 805 is fixedly communicated with the inner cavity of the first groove 301.

[0034] During use, when it is necessary to disassemble and separate the socket 1 and the plug 102, the staff first manually opens the valve switch 701, so that the gas inside the airbag 607 is discharged to the outside through the conduit 7. Subsequently, the staff first presses the fixing block 303. After the fixing block 303 is pressed, it pushes the sealing plate 302 to retract into the first groove 301 and compresses the first spring 304 until the fixing block 303 completely retracts into the first groove 301. At the same time, the sealing plate 302 squeezes the gas inside the first groove 301 and transports it into the hollow cavity 805 through the third pipeline 808. Then, the gas discharged into the hollow cavity 805 pushes the slider 806 to slide away from the third groove 802. At this time, the self-locking block 804 moves synchronously with the slider 806 through the pull rod 807 and compresses the third spring 803 until the self-locking block 804 moves out of the limiting groove 809 and retracts into the third groove 802, thus releasing the self-locking of the plug 102 and the socket 1. Then, the staff moves the plug 102 away from the socket 1. The plug 102 drives the second fixing plate 103 and the plug-in frame 4 to move synchronously, so that the plug-in frame 4 moves out of the first sealing groove 403. At the same time, the fixing groove 305 is separated from the plugging rod 3, so that the staff can quickly disassemble and separate the socket 1 and the plug 102 without using professional tools;

[0035] When it is necessary to dock the socket 1 and the plug 102, the staff first inserts the guide rod 5 into the chute provided on the sliding seat 501, and then pushes the plug 102 towards the socket 1. As a result, the plug 102 can move smoothly towards the socket 1 under the limit guidance of the sliding of the guide rod 5 on the sliding seat 501, avoiding inaccurate docking between the plug 102 and the socket 1 and causing bending and damage to the pins on the plug 102;

[0036] Then, when the plug 102 moves a certain distance towards the socket 1 and the insertion rod 3 is inserted into the fixed slot 305, the fixed block 303 is pushed by the outer wall of the second fixing plate 103 to retract the inner groove 301 of the sealing plate 302 and compress the first spring 304 until the fixed block 303 completely retracts into the groove 301;

[0037] At this time, the guide rod 5 is inserted into the second groove 801, causing the self-locking block 804 to be pushed by the guide rod 5 to retract towards the third groove 802 and compress the third spring 803 until the self-locking block 804 completely retracts into the third groove 802. Then, continue to move the plug 102 closer to the socket 1. The plug 102 drives the second fixing plate 103 to move synchronously. Until when the groove 301 moves out of the fixed slot 305, the plug 102 is in contact with the socket 1, thus completing the docking of the plug 102 and the socket 1. Then, the compressed first spring 304 generates a thrust force, pushing the sealing plate 302 to drive the fixed block 303 to move out of the groove 301 and snap onto the outer wall of the second fixing plate 103, thereby being able to provide limit fixation for the plug 102 and the socket 1;

[0038] At the same time, the self-locking block 804 coincides with the limiting groove 809. Then, the compressed third spring 803 generates a thrust force, pushing the self-locking block 804 out of the third groove 802, causing the self-locking block 804 to be inserted into the limiting groove 809, thereby achieving internal limit self-locking for the plug 102 and the socket 1 and improving the firmness after the docking of the plug 102 and the socket 1;

[0039] Meanwhile, when the plug 102 moves towards the socket 1, the plug 102 drives the insertion frame 4 to move synchronously. Then, when the plug 102 is in contact and fitted with the socket 1, the insertion frame 4 is inserted into the first sealing groove 403. At this time, the sealing gasket 401 is closely attached to the inner wall of the socket 1 under the extrusion of the insertion frame 4, thereby ensuring the sealing of the joint surface between the plug 102 and the socket 1 and achieving the effects of dust prevention and waterproofing.

[0040] Embodiment 2: Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5, a new energy vehicle connector. The air supply component includes a sleeve 6 and a piston disc 601 slidably connected within the sleeve 6. A second spring 602 is fixedly connected between the piston disc 601 and the inner wall of the sleeve 6. Guide grooves are provided on both the first fixing plate 101 and the insertion rod 3, and a pull rope 603 is arranged within the guide grooves. One end of the pull rope 603 is fixedly connected to the piston disc 601, and the other end is fixedly connected to the sealing plate 302. A first pipeline 604 is fixedly communicated with the sleeve 6. The sleeve 6 is fixedly communicated with an airbag 607 through a second pipeline 606. A second sealing groove 608 is formed on the outer side wall of the insertion frame 4.

[0041] An activated carbon filter screen 605 is provided inside the air inlet end of the first pipeline 604.

[0042] When the staff presses the fixing block 303, causing the fixing block 303 to retract into the first groove 301 and compress the first spring 304, the pull rope 603 becomes slack. Then, the stretched second spring 602 drives the piston disc 601 to slide away from the side of the first pipeline 604 within the sleeve 6 under its own elastic contraction force, and draws in external gas through the first pipeline 604. The external gas contacts the activated carbon filter screen 605 through the first pipeline 604. Since the activated carbon has a developed pore structure and rich microporous tissues inside, these microporous tissues have a strong adsorption force field. When the gas contacts the activated carbon, the strong adsorption force field of the activated carbon micropores can adsorb the particulate matter in the air into the micropores, thereby achieving the effect of purifying the gas. Then, the purified gas enters the sleeve 6 through the first pipeline 604 and is temporarily stored.

[0043] Then, when the staff releases the fixing block 303, the compressed first spring 304 generates a thrust, pushing the sealing plate 302 to drive the fixing block 303 out of the first groove 301 and engage with the side surface of the second fixing plate 103. The sealing plate 302 pulls the piston disc 601 to slide towards the side close to the first pipeline 604 within the sleeve 6 through the pull rope 603. Then, the piston disc 601 squeezes the gas temporarily stored within the sleeve 6 and transports it into the airbag 607 through the second pipeline 606. Check valves are provided on both the first pipeline 604 and the second pipeline 606, thereby inflating the airbag 607. Therefore, the airbag 607 expands and fits tightly with the second sealing groove 608, thereby improving the sealing performance of the joint surface between the plug 102 and the socket 1, and effectively preventing dust in the external air from entering the plug 102 and the socket 1.

[0044] Example 3: Refer to Figure 1 、 Figure 2 and Figure 3, A new energy vehicle connector, which is basically the same as that in Embodiment 1. Further, wiring housings 2 are fixedly connected to both the socket 1 and the plug 102, and a plurality of groups of wire grooves are provided in the wiring housings 2 at equal intervals; when a plurality of wire harnesses pass through the plurality of groups of wire grooves inside the wiring housings 2 and penetrate into the socket 1 and the plug 102 respectively, the plurality of groups of wire grooves at equal intervals can arrange the plurality of wire harnesses in an equal-distance and neat manner, so as to facilitate the maintenance of the wire harnesses when the wire harnesses are damaged.

[0045] It further includes a rubber ring 201, and the rubber ring 201 is arranged in the wire groove; the rubber ring 201 can provide protection for the wire harnesses penetrating into the wire grooves, prevent the sharp corners at both ends of the wire grooves from wearing the wire harnesses, and thus extend the service life of the wire harnesses.

[0046] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention.
