Technical Field
[0001] This utility model relates to the field of charging plug technology, and more specifically, to a device for preventing the charging plug of a new energy vehicle from detaching. Background Technology
[0002] With the transformation of the global energy structure and the increasing awareness of environmental protection, new energy vehicles, as the core carrier of green travel, are experiencing explosive growth in their industrial scale. In the daily use of new energy vehicles, the charging process is crucial, and a stable connection between the charging plug and the vehicle's charging port is the foundation for ensuring efficient and safe charging. However, existing new energy vehicle charging plugs generally suffer from the technical bottleneck of being prone to loosening during actual use, and this defect has become an important factor restricting the reliability of charging.
[0003] Traditional charging plugs and car charging ports typically use a direct-insertion structure for connection. This design makes the charging plug susceptible to external interference and may fall off due to accidental impact, which seriously affects the stability of the connection. While existing anti-drop mechanisms enhance connection stability to some extent by integrating them into the charging port, this not only increases the manufacturing cost of the car charging port but also negatively impacts the actual performance of the charging plug due to the increased structural complexity. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a new energy vehicle charging plug anti-disconnection device, which solves the problem that the existing technology enhances the stability of the plug connection to a certain extent by integrating it into the charging port, but this increases the manufacturing cost of the car charging port.
[0005] To solve the above technical problems, this utility model provides the following technical solution: a new energy vehicle charging plug anti-disconnection device, including an outer protective shell and a charging gun head, a movable groove is provided on the upper left side of the charging gun head, a movable plate is slidably connected to the inner wall of the movable groove, a limiting plate is fixedly installed on the top left side of the movable plate, a limiting groove is provided on the upper right side of the outer protective shell, and a slot is provided in the middle of the outer protective shell.
[0006] The outer protective shell has a groove on its upper inner side, a slide plate is slidably connected to the upper part of the inner wall of the groove, a button is fixedly installed in the middle of the slide plate, and an elastic element is fixedly installed at the bottom.
[0007] The button is slidably connected to the upper part of the charging gun head, and its bottom end is fixedly installed between the moving groove and the moving plate.
[0008] The bottom end of the elastic element is fixedly installed on the inner bottom wall of the slide groove, and the slide groove and the moving groove are connected.
[0009] The outer protective shell has a rubber block fixedly installed on its right end, and the inner wall of the rubber block has a fitting groove. The outer protective shell has a positioning ring fixedly installed on its left side, and the positioning ring has a rubber ring fixedly installed on its outer side.
[0010] The positioning ring is inserted into the inner ring wall of the rubber block, and the rubber ring is inserted into the inner wall of the mating groove.
[0011] The left side of the movable plate is inserted into the inner wall of the limiting groove, the limiting plate is inserted into the upper side of the inner wall of the limiting groove, and the left part of the charging gun head is inserted into the inner wall of the slot.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In the above solution, when the charging gun head is inserted into the outer protective shell, the left side of the moving plate is simultaneously inserted into the limiting slot, causing the limiting plate to precisely engage with the limiting slot, thereby achieving a stable lock on the charging gun head, preventing the charging gun head from accidentally falling off, and helping to reduce the production cost of the charging port, thus optimizing the actual performance of the charging gun head.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0023] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a new energy vehicle charging plug anti-detachment device, including an outer protective shell 1 and a charging gun head 3. The outer protective shell 1 is the outer shell of the vehicle charging port, and a limiting groove 12 is opened on the outer protective shell 1 to reduce production costs. A movable groove 13 is opened on the upper left side of the charging gun head 3. A movable plate 8 is slidably connected to the inner wall of the movable groove 13. A limiting plate 9 is fixedly installed on the top left side of the movable plate 8. A limiting groove 12 is opened on the upper right side of the outer protective shell 1. A slot 11 is opened in the middle of the outer protective shell 1. The left side of the movable plate 8 is inserted into the inner wall of the limiting groove 12. The limiting plate 9 is inserted into the upper side of the inner wall of the limiting groove 12. The left side of the charging gun head 3 is inserted into the inner wall of the slot 11. Thus, the charging gun head 3 is restricted from the outer protective shell 1 by the cooperation between the movable plate 8, the limiting plate 9, and the limiting groove 12, preventing the charging gun head 3 from detaching from the outer protective shell 1.
[0024] First, the moving plate 8 moves down along the inner wall of the moving groove 13, and its left side descends along the inner wall of the limiting groove 12, thereby releasing the insertion state between the limiting plate 9 and the limiting groove 12. Then, the charging gun head 3 can be pulled to the right to disengage its left side from the slot 11 so that the charging gun head 3 can be removed. Conversely, during insertion, the left side of the charging gun head 3 is inserted into the inner wall of the slot 11, and the moving plate 8 is simultaneously inserted into the inner wall of the limiting groove 12. Afterward, the limiting plate 9 and the limiting groove 12 continue to be engaged to fix the charging gun head 3 and the outer protective shell 1, preventing it from falling off, and also reducing the production cost of the outer protective shell 1.
[0025] Example 2: Based on Example 1, in order to facilitate contact with the charging gun head 3, a sliding groove 6 is provided on the upper side of the inner side of the outer protective shell 1. A sliding plate 5 is slidably connected to the upper part of the inner wall of the sliding groove 6. A button 2 is fixedly installed in the middle of the sliding plate 5, and an elastic element 7 is fixedly installed at the bottom. The button 2 is slidably connected to the upper part of the charging gun head 3, and its bottom end is fixedly installed between the moving groove 13 and the moving plate 8. Thus, by pressing the button 2 downward, the moving plate 8 is moved downward synchronously. The bottom end of the elastic element 7 is fixedly installed on the inner bottom wall of the sliding groove 6. The sliding groove 6 and the moving groove 13 are interconnected, so that the elastic force of the elastic element 7 keeps the limiting plate 9 and the limiting groove 12 in an inserted state.
[0026] First, press button 2 to move the slide plate 5 down along the inner wall of the slide groove 6, and squeeze the elastic element 7 to compress it. At the same time, the moving plate 8 will move down along the inner wall of the moving groove 13, and its left side will descend along the inner wall of the limiting groove 12, thereby releasing the insertion state between the limiting plate 9 and the limiting groove 12. Then, the charging gun head 3 can be pulled to the right to remove it. Conversely, when inserting, insert the left part of the charging gun head 3 into the inner wall of the slot 11, and at the same time, the moving plate 8 is inserted into the inner wall of the limiting groove 12. After that, you can release button 2, and use the elastic force of the elastic element 7 to push the slide plate 5 up to reset, and keep the limiting plate 9 and the limiting groove 12 in a locked state to fix the charging gun head 3 and the outer protective shell 1, prevent it from falling off, and reduce the production cost of the outer protective shell 1.
[0027] Example 3: Based on Example 2, in order to increase the stability of the insertion and improve the sealing performance after insertion, a rubber block 4 is fixedly installed on the right end of the outer protective shell 1. The inner wall of the rubber block 4 is provided with a fitting groove 10. A positioning ring 15 is fixedly installed on the left side of the outer protective shell 1. A rubber ring 14 is fixedly installed on the outer side of the positioning ring 15. The positioning ring 15 is inserted into the inner ring wall of the rubber block 4, and the rubber ring 14 is inserted into the inner wall of the fitting groove 10. Thus, the sealing performance and stability between the charging gun head 3 and the outer protective shell 1 are increased by utilizing the cooperation between the rubber ring 14 and the fitting groove 10.
[0028] When the charging gun head 3 is inserted into the outer protective shell 1, the positioning ring 15 will be inserted into the inner wall of the rubber block 4, and the rubber ring 14 will be inserted into the inner wall of the mating groove 10. This will increase the stability of the insertion between the outer protective shell 1 and the charging gun head 3, and also improve the sealing of the insertion. Conversely, when the charging gun head 3 is pulled out, the positioning ring 15 will disengage from the inner wall of the rubber block 4, and the rubber ring 14 will disengage from the mating groove 10. This will facilitate subsequent use, and the positioning ring 15 will facilitate the positioning and insertion of the charging gun head 3, thereby improving the performance of the charging gun head 3.
[0029] The working process of this utility model is as follows:
[0030] When in use, first press button 2 to move the slide plate 5 down along the inner wall of the slide groove 6 and squeeze the elastic element 7 to compress it. At the same time, the moving plate 8 will move down along the inner wall of the moving groove 13, and its left side will descend along the inner wall of the limiting groove 12, thereby releasing the insertion state between the limiting plate 9 and the limiting groove 12. Then, the charging gun head 3 can be pulled to the right to disengage its left side from the slot 11 so that the charging gun head 3 can be removed. Conversely, when inserting, insert the left side of the charging gun head 3 into the inner wall of the slot 11, and at the same time, the moving plate 8 is inserted into the inner wall of the limiting groove 12. After that, you can release button 2 and use the elastic force of the elastic element 7 to push the slide plate 5 up to reset, and keep the limiting plate 9 and the limiting groove 12 in a locked state to fix the charging gun head 3 and the outer protective shell 1, prevent it from falling off, and reduce the production cost of the outer protective shell 1.
[0031] When the charging gun head 3 is inserted into the outer protective shell 1, the positioning ring 15 will be inserted into the inner wall of the rubber block 4, and the rubber ring 14 will be inserted into the inner wall of the mating groove 10. This will increase the stability of the insertion between the outer protective shell 1 and the charging gun head 3, and also improve the sealing of the insertion. Conversely, when the charging gun head 3 is pulled out, the positioning ring 15 will disengage from the inner wall of the rubber block 4, and the rubber ring 14 will disengage from the mating groove 10. This will facilitate subsequent use, and the positioning ring 15 will facilitate the positioning and insertion of the charging gun head 3, thereby improving the performance of the charging gun head 3.
