[0002] As we all know, in the field of new energy electric vehicles, the charging gun is a key component connecting the vehicle and the charging infrastructure. The quality of its design directly affects the safety, stability, and user experience of the charging process. After being inserted into the vehicle's charging port, traditional charging guns rely solely on physical friction to maintain the connection. This connection method is easily affected by external factors such as vibration, collision, and human factors. It can cause the charging gun to accidentally fall off, interrupting the charging process and even posing a safety hazard.

[0003] In addition, since the charging process involves high voltage and high current, once the connection between the charging gun and the vehicle charging port is unstable, it may cause circuit damage, electric shock accidents or other electrical failures, which poses a potential threat to the user's personal safety and the vehicle's operating safety. Therefore, it is necessary to propose a solution to this technical problem. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-4The utility model is a charging gun for new energy electric vehicles with stable charging, comprising a charging gun body 1, a charging head 2 at one end of the charging gun body 1, a fixing box 3 at the top of the charging gun body 1, a lifting slot is provided between the fixing box 3 and the top of the charging head 2, a lifting plate 4 is provided on the lifting slot, the lifting plate 4 extends to the top of the charging head 2, a guide mechanism and a locking mechanism are provided between the lifting plate 4 and the lifting slot, an inclined slot is provided at the bottom of one end of the lifting plate 4, and a lifting slot is provided at one end of the lifting slot. There is a fastening groove, a support frame is provided on the fastening groove, a driving motor 5 is provided on the support frame, a screw rod 6 is provided at the output end of the driving motor 5, a bearing seat is provided between the screw rod 6 and the fastening groove, a sliding block 7 is provided on the fastening groove, a first threaded hole is opened on the sliding block 7, the screw rod 6 passes through the first threaded hole, an inclined plate 8 is provided between the bottom end of the sliding block 7 and the fastening groove, and a maintenance mechanism is provided on the fixing box 3. In this embodiment, when the charging head 2 of the charging gun body 1 is inserted into the socket of the new energy vehicle, charging is carried out. Electrical operation, at this time, by controlling the output end of the drive motor 5 to drive the screw rod 6 to rotate, the screw rod 6 is stably rotated in the fastening groove through the bearing seat. At this time, the screw rod 6 passes through the first threaded hole of the sliding block 7, so that the sliding block 7 can move linearly in the fastening groove, and the sliding block 7 drives the inclined plate 8 to move. The inclined plate 8 contacts and pushes the inclined groove opened at the bottom of one end of the lifting plate 4, so that the lifting plate 4 moves upward linearly in the lifting groove through the guide mechanism, so that the lifting plate 4 is firmly pressed against the charging socket, making the charging head 2 more firmly and reliably inserted into the charging socket, preventing foreign objects from accidentally touching the charging line and causing the charging head 2 to be detached from the charging socket. After charging is completed, the charging pile will stop charging after receiving the full charge information. At this time, the output end of the drive motor 5 is controlled to rotate in the opposite direction to reset the sliding block 7. The lifting plate 4 can be reset through the locking mechanism to facilitate the removal of the charging gun body 1. The switch signal between the charging pile and the drive motor 5 is a common control system in existing life and is not described in detail in this structure. For example, a PLC control system can automatically fasten the charging head 2 to the charging socket of the new energy vehicle.

[0027] In this solution, the maintenance mechanism includes a slot and a second threaded hole. The slot is opened at the top of the fixed box 3, the slot is connected to the fastening slot, and a limiting slot is opened at one end of the slot. A maintenance cover 9 is provided on the slot, and a limiting block 10 is provided between the maintenance cover 9 and the limiting slot. The second threaded hole is opened at one end of the fixed box 3, and a threaded column 11 is provided on the second threaded hole. A limiting plate 12 is provided on the threaded column 11, and the limiting plate 12 is against one end of the limiting block 10. By holding the limiting plate 12 and rotating it, the threaded column 11 leaves the second threaded hole, and the limiting plate 12 leaves one end of the limiting block 10, thereby pulling the limiting block 10, and the limiting block 10 drives the maintenance cover 9 to move, and the maintenance cover 9 is removed, thereby facilitating maintenance of the drive motor 5 through the slot.

[0028] In this solution, the guide mechanism includes a guide block 13 and a guide groove. The guide groove is opened on one side of the lifting groove. The guide block 13 is installed on one side of the lifting plate 4. The guide block 13 is slidably connected to the guide groove. When the lifting plate 4 moves, it drives the guide block 13 to move. The guide block 13 moves linearly in the guide groove, so that the lifting plate 4 can stably move linearly in the lifting groove.

[0029] In this solution, the guide mechanisms are provided with two and are symmetrically arranged. By providing two and symmetrically arranged guide mechanisms, the lifting plate 4 can move linearly in the lifting slot more stably.

[0030] In this solution, the guide groove and the guide block 13 are both T-shaped structures. The guide block 13 with the T-shaped structure is located in the guide groove, which can prevent the guide block 13 from escaping from the guide groove.

[0031] In this solution, the locking mechanism includes an iron magnet 14 and an iron sheet 15. The iron sheet 15 is embedded in the bottom end of the lifting plate 4, and the iron magnet 14 is embedded in the bottom end of the lifting slot. The iron magnet 14 adsorbs the iron sheet 15, so that the lifting plate 4 can be stably pressed against the top of the charging head 2 when not in use, which is convenient for use.

[0032] In this solution, a rubber pad 16 is provided on the top of the lifting plate 4. The rubber pad 16 can improve the damping performance and more firmly press against the top of the socket, so that the charging gun body 1 is fixed more stably.

[0033] In this solution, the rubber pad 16 is provided with anti-skid grooves, and the anti-skid effect of the rubber pad 16 can be improved by the anti-skid grooves of the rubber pad 16.
