[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as a power source and integrate advanced technologies in vehicle power control and drive, forming vehicles with advanced technical principles, new technologies, and new structures. With development, the number of new energy vehicles in use is increasing, which can provide greater convenience for people's travel. The use of new energy vehicles requires charging, which requires the use of charging guns for new energy vehicles. A search revealed Chinese patent CN115911954A, which discloses a replaceable charging gun head, relating to the field of charging guns. The gun head includes a first Torx head flat-tail self-tapping screw on its outer side, and a gun head rubber pad connected to one side of the gun head. A terminal is mounted on one side of the rubber pad, and an O-ring is positioned on the front side of the terminal, located on one side of the rubber pad. The terminal is installed inside a terminal cover, and a second Torx head flat-tail self-tapping screw is located inside the terminal cover. This invention enables the disassembly of the gun head and the gun housing, as well as the disassembly of the gun housing and the waterproof ring block. This allows for easy removal of the gun head from one side of the gun housing when it is damaged, eliminating the need to replace the entire charging gun, reducing waste. The replacement process is convenient, requiring no specialized personnel, and is time-saving and labor-saving, requiring only the tightening of the corresponding screws.

[0003] The disassembly process of the above-mentioned technical solution requires turning multiple screws, making the disassembly and assembly process cumbersome. It cannot quickly disassemble and fix the charging gun body and wires by rotating and snapping, nor can it limit and fix the connection structure of the charging gun after installation, which is not conducive to fully improving the efficiency of disassembly and the safety of use.

[0016] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0017] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a split-type replaceable charging gun for charging new energy vehicles.

[0018] The specific technical solution includes a sleeve 1 and a detachable connecting assembly 4; like Figure 1-4As shown, the sleeve 1 has a bayonet 2, and the sleeve 1 has an internal thread 3. The bayonet 2 facilitates the installation of the screw 8, and at the same time, the bayonet 2 can conveniently limit the insertion rod 406. The internal thread 3 can connect with the external thread 5. The detachable connection assembly 4 is installed on the sleeve 1. The detachable connection assembly 4 is used for disassembling the charging gun structure. The detachable connection assembly 4 includes a wire 401, a connector 402, a sliding ring 403, a fixing ring 404, a spring 405, and an insertion rod 406. The wire 401 can deliver electrical energy to the charging gun body through the connector 402. The connector 402 can support the wire 401. The sliding ring 403 can drive the spring 405 to extend and can also drive the insertion rod 406 to move. The fixing ring 404 can fix the spring 405 away from the sliding ring 403. One end is fixed, and the fixing ring 404 can limit the insertion rod 406. The two ends of the spring 405 are fixedly connected to the sliding ring 403 and the fixing ring 404 respectively. The spring 405 can drive the sliding ring 403 to reset. The insertion rod 406 can be inserted into the bayonet 2 and then fixed to the fixing ring 404. The wire 401 is fixedly connected to the connector 402. The connector 402 passes through the sleeve 1. The connector 402 has an external thread 5 on its outside. The external thread 5 is threadedly connected to the internal thread 3. The sliding ring 403 is slidably sleeved on the outside of the connector 402. The fixing ring 404 is fixedly sleeved on the outside of the connector 402. The spring 405 is installed between the sliding ring 403 and the fixing ring 404. The insertion rod 406 is fixedly connected to the sliding ring 403. The insertion rod 406 slides through the fixing ring 404 and the bayonet 2.

[0019] according to Figure 3As shown, when the insertion rod 406 is inserted into the bayonet 2, the spring 405 is in its original length. By holding the anti-slip groove 12 on the right end of the connector 402 and pulling the sliding ring 403 with the fingers of the hand holding the connector 402, the sliding ring 403 moves to the right, which can pull the spring 405 to the right. The left end of the spring 405 is fixed by the fixing ring 404, which is fixed to the connector 402, so the spring 405 can extend. The spring 405 can exert a leftward pulling force on the sliding ring 403, and at the same time, the sliding ring... When 403 moves to the right, it can pull the insertion rod 406 to move to the right inside the fixing ring 404. The left end of the insertion rod 406 can move out of the bayonet 2 to the right, and the diameter of the left end of the insertion rod 406 is larger than the diameter that can slide inside the fixing ring 404. The fixing ring 404 is sleeved on the inner wall outside the insertion rod 406 and fits against the insertion rod 406, which can prevent the insertion rod 406 from moving out of the fixing ring 404. After the insertion rod 406 is pulled out from the bayonet 2, the internal thread 3 is rotated by turning the sleeve 1. The sleeve 1 rotates around its own central axis, and the internal thread 3 and the external thread 5 are... Rotation and relative movement occur, allowing the connector 402 to be pulled out of the sleeve 1, enabling disassembly of the gun body and wire 401. The connector 402 is screwed into the sleeve 1, and the internal thread 3 and external thread 5 are fixed together, securing the connector 402 to the sleeve 1. At this point, the insertion rod 406 aligns with the bayonet 2. Releasing the sliding ring 403 causes the spring 405 to reset, moving the sliding ring 403 to the left. The sliding ring 403 then moves the insertion rod 406 to the left, causing the insertion rod 406 to slide within the fixing ring 404 and enter the bayonet 2. The insertion rod 406 then aligns with the bayonet 2. The direction of rotation around the central axis of the sleeve 1 is fixed, which can prevent the insertion rod 406 from rotating around the central axis of the sleeve 1. After the insertion rod 406 is limited, it can prevent the fixing ring 404 from rotating around the central axis of the sleeve 1. The fixing ring 404 can prevent the connector 402 from rotating around the central axis of the sleeve 1. The external thread 5 on the connector 402 is limited, which can prevent relative rotation between the external thread 5 and the internal thread 3. It can prevent the connector 402 from accidentally rotating and dislodging from the sleeve 1, and can better limit the wire 401 on the connector 402.

[0020] like Figure 1-2 As shown, the upper gun body 6 and the lower gun body 7 are inserted inside the sleeve 1. The upper gun body 6 and the lower gun body 7 can better protect the electrical structure inside the gun body. The screw 8 is inserted inside the bayonet 2. By inserting the screw 8 into the bayonet 2 and then screwing the screw 8 into the side wall of the upper gun body 6 and the lower gun body 7, the screw 8 can fix the sleeve 1 to the upper gun body 6 and the lower gun body 7 through the bayonet 2. The screw 8 is fixedly inserted into the side wall of the upper gun body 6 and the lower gun body 7. The connector 402 is inserted into one end of the upper gun body 6 and the lower gun body 7.

[0021] like Figure 1-2As shown, a sealing ring 9 is installed between the upper gun body 6 and the lower gun body 7. The sealing ring 9 can improve the sealing between the upper gun body 6 and the lower gun body 7.

[0022] like Figure 1-2 As shown, a plug 10 is provided at one end of the upper gun body 6 and the lower gun body 7. The plug 10 can be connected to the charging port of a new energy vehicle, which can facilitate charging of the new energy vehicle. A screw 8 is provided on the side wall of the plug 10 to fix and connect with the upper gun body 6 and the lower gun body 7.

[0023] like Figure 1-2 As shown, the upper gun body 6 is equipped with a mechanical lock buckle 11, which is connected to the vehicle locking structure inside the charging port of the new energy vehicle, and can prevent the charging gun from being accidentally pulled out.

[0024] like Figure 1 and Figure 3-4 As shown, the outer sidewall of the connector 402 is provided with an anti-slip groove 12, which can increase the friction between the palm and the connector 402.
