[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 2 and Figure 3This utility model provides an embodiment of an AC charging pile with a protective mechanism, comprising a foundation 1, a motor 3 fixedly connected to the bottom of the foundation 1, a worm gear 4 fixedly connected to the output end of the motor 3, the motor 3 driving the worm gear 4 to rotate, an inner groove worm wheel 5 meshing with the outer wall of the worm gear 4, a plurality of connecting plates 6 fixedly connected at equal intervals to the outer wall of the inner groove worm wheel 5, and a protective plate 7 fixedly connected to the end of each of the multiple connecting plates 6, the worm gear 4 driving the inner groove worm wheel 5, the connecting plates 6 and the protective plates 7 to move upward synchronously, and the four corners of the top wall of the foundation 1 are fixedly... A protective rod 8 is fixedly connected to the base 1. Each adjacent side of the multiple protective rods 8 is fixedly connected to a sliding groove 9. The protective rods 8 guide the protective plate 7 through the sliding grooves 9. The inner sides of the multiple sliding grooves 9 are slidably connected to the corresponding protective plates 7. A height adjustment mechanism 2 is installed on the top of the base 1. The height adjustment mechanism 2 is used to adjust the height of the AC charging pile with the protective mechanism. A stabilizing frame 12 is installed on the top left and right sides of the outer wall of the motor 3. The front and rear sides of the two stabilizing frames 12 are threaded with screws 13. Screws 13 are used to fix the stabilizing frame 12.

[0032] Specifically, the worm gear 4 is driven to rotate by the power provided by the motor 3. When the worm gear 4 rotates, it meshes with the inner groove worm wheel 5, thereby driving the inner groove worm wheel 5 to move upward. At the same time as the inner groove worm wheel 5 moves upward, it drives the corresponding protective plate 7 to move upward synchronously through multiple connecting plates 6. While the multiple protective plates 7 move upward, they are guided by the sliding grooves 9 opened on multiple protective rods 8 to seal the AC charging pile. The stability frame 12, which is fixed to the motor 3 by screw 13, can improve its stability.

[0033] Reference Figure 4 and Figure 5 The height adjustment mechanism 2 includes a fixed plate 201, the bottom of which is located in the middle of the top wall of the foundation 1. A fixed rod 202 is fixedly connected to the top of the fixed plate 201. The fixed plate 201 is used to install the fixed rod 202. An adjustment groove 203 is provided on the inner side of the fixed rod 202. An extension rod 204 is slidably connected to the middle of the fixed rod 202. A fixing buckle 205 is fixedly connected to the bottom front side of the extension rod 204. An organism 206 is fixedly connected to the top of the extension rod 204. 4. The height of the body 206 is fixed by the cooperation of the fixing buckle 205 and the adjustment groove 203. Threaded holes 14 are opened at the four corners of the top of the fixing plate 201. Screws 15 are threaded to the inside of the multiple threaded holes 14. Screws 15 and threaded holes 14 are used to install the fixing plate 201. Display screens 18 are fixedly connected to the top of the front side of the multiple bodies 206. Operation keys 19 are installed in the middle of the front side of the body 206. Display screens 18 and operation keys 19 are used to control the AC charging pile.

[0034] Specifically, rotating the extension rod 204 causes the fixing buckle 205 fixed underneath to slide out of the adjustment groove 203 opened in the fixing rod 202. Then, the extension rod 204 is pulled upward to adjust the height of the body 206. When the body 206 reaches the appropriate height, the extension rod 204 is rotated in the opposite direction to cause the fixing buckle 205 fixed underneath to slide into the adjustment groove 203 opened in the corresponding position in the fixing rod 202, thereby fixing the position of the extension rod 204. The fixing plate 201 is fixed to the foundation 1 through the threaded hole 14 opened on it and the screw 15. The display screen 18 is used to display charging information, and the operation key 19 can control the AC charging pile.

[0035] Reference Figure 1 , Figure 2 and Figure 3 Pressure bars 10 are fixedly connected to the outer walls of multiple protective bars 8. Wires 11 are fixedly connected to the bottom of multiple pressure bars 10. The bottom of multiple wires 11 is fixedly connected to the motor 3. When pressure is applied, the pressure bars 10 alert the motor 3 via wires 11. Wires 26 are fixedly connected to the top of multiple pressure bars 10. An alarm 17 is fixedly connected to the top of multiple wires 26. The alarm 17 is connected to the pressure bars 10 via wires 26. A waterproof cover 20 is fixedly connected to the top of multiple protective bars 8. A water channel 21 is provided on the top of the waterproof cover 20 to guide the water flow on the waterproof cover 20.

[0036] Specifically, the pressure bar 10 installed outside the guard rod 8 will notify the motor 3 to start via wire 11 after being subjected to pressure exceeding the set tolerance value. After the pressure bar 10 is subjected to pressure exceeding the set tolerance value, it will activate the alarm 17 to issue a warning via wire 21. The waterproof cover 20 fixed on the guard rod 8 can guide rainwater through the water channel 21 opened on it.

[0037] Working principle: When the AC charging pile needs protection, the motor 3 installed under the foundation 1 is started first. The power provided by the motor 3 drives the worm 4 to rotate. When the worm 4 rotates, it will mesh with the inner groove worm wheel 5, thereby driving the inner groove worm wheel 5 to move upward. At the same time as the inner groove worm wheel 5 moves upward, it will drive the corresponding protective plate 7 to move upward synchronously through multiple connecting plates 6. As the multiple protective plates 7 move upward, they will be guided by the sliding grooves 9 opened on multiple protective rods 8 to seal the AC charging pile, thereby achieving the protection effect of the AC charging pile.

[0038] When installing an AC charging station, if its height needs to be adjusted, first rotate the extension rod 204 so that the fixing buckle 205 fixed underneath slides out of the adjustment groove 203 opened in the fixing rod 202. Then pull the extension rod 204 upward to adjust the height of the body 206. When the body 206 reaches the appropriate height, rotate the extension rod 204 in the opposite direction so that the fixing buckle 205 fixed underneath slides into the adjustment groove 203 opened in the corresponding position in the fixing rod 202. This fixes the position of the extension rod 204. The fixing plate 201 is used to fix the height adjustment mechanism 2 as a whole, thus realizing the effect of convenient adjustment of the height of the AC charging station.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
