[0002] The function of a charging pile is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding operations such as charging method, charging time, and cost data printing. The charging pile display can display data such as charging amount, cost, and charging time.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 and Figure 4 The utility model provides an embodiment: a protective base for a tram charging pile, including a base 1 and a pile body 2, a spring rod 3 is fixedly connected to the outside of the base 1, the other end of the spring rod 3 is fixedly connected to an anti-collision beam 4, a connecting rod 5 is rotatably connected to the inside of the anti-collision beam 4, a sliding rod 7 is fixedly connected to the outside of the base 1, a sliding block 6 is slidably connected to the outer periphery of the sliding rod 7, one end of the connecting rod 5 away from the anti-collision beam 4 is rotatably connected to the outside of the sliding block 6, a compression spring 8 is sleeved on the outside of the sliding rod 7, and the side of the sliding block 6 away from the connecting rod 5 is fixedly connected to the end of the compression spring 8;

[0031] Specifically, after the base 1 is pre-buried in the ground, the base 1 and the pile body 2 are combined to complete the installation of the entire charging pile, and then the anti-collision beam 4 and the spring rod 3 cooperate to preliminarily eliminate the impact force, and then the remaining impact force will cause the anti-collision beam 4 to displace, and at the same time, the connecting rod 5 will be tilted, and the position of the end of the connecting rod 5 away from the anti-collision beam 4 will be changed, so that the position of the slider 6 can be changed, and in cooperation with the slide bar 7, the impact force can be eliminated again, and at the same time, when the slider 6 moves, it will also squeeze the compression spring 8, causing the compression spring 8 to deform, thereby further eliminating the impact force, and after the collision is completed, the anti-collision beam 4 can be retracted for the next protection.

[0032] Reference Figure 1-Figure 3 A mounting assembly is provided in the middle of the base 1, and the mounting assembly includes a rotating shaft 13, the rotating shaft 13 is fixedly connected to the inner side of the base 1, and a clamping plate 14 is rotatably connected to the outside of the rotating shaft 13. A notch 11 is provided on the inner side of the base 1, and the clamping plate 14 is provided in the middle of the notch 11. A plurality of bayonet holes 12 are provided on the outer side of the pile body 2, and the bayonet holes 12 and the clamping plate 14 are clamped together. A compression spring 15 is fixedly connected to the top of the clamping plate 14, and the other end of the compression spring 15 is fixedly connected to the inside of the base 1;

[0033] Specifically, during installation, the pile body 2 is inserted from the upper part of the base 1, and then the clamping plate 14 is squeezed by the pile body 2 and rotates, and then the clamping plate 14 is flipped outward by the compression spring 15 so that the clamping plate 14 and the bayonet 12 are clamped together, thereby completing the installation of the base 1 and the pile body 2. The operation is simple, the installation is very convenient, and the pile body 2 can be prevented from falling out of the top of the base 1.

[0034] Reference Figure 1 , Figure 2 and Figure 5 A motor 16 is fixedly connected to the inner side of the base 1, and a fan 17 is fixedly connected to the output end of the motor 16. A plurality of vents 9 are provided on the side of the base 1, and the fan 17 is aligned with the vents 9. A drainage groove 10 is provided at the bottom of the base 1, and the drainage groove 10 is inclined, and the end of the drainage groove 10 is located on the outer side of the base 1;

[0035] Specifically, after the pile body 2 is installed and used, the motor 16 can be driven synchronously to make the fan 17 rotate, so that the outer wall of the pile body 2 can be cooled, thereby reducing the heat accumulation generated when the pile body 2 is working, thereby ensuring the long-term normal use of the pile body 2. At the same time, a drainage groove 10 is opened at the bottom of the base 1. When water enters the bottom of the base 1, rainwater can flow out through the drainage groove 10, thereby ensuring the cleanliness of the inside of the base 1 and avoiding water accumulation and damage to the motor 16.

[0036] Working principle: When in use, align the middle of the pile body 2 and the base 1, and then press the pile body 2 downward. During the downward falling process of the pile body 2, the clamping plate 14 can be turned over. When the pile body 2 falls to the bottom of the base 1, the compression spring 15 pops up the clamping plate 14, so that the clamping plate 14 and the bayonet 12 are connected, thereby completing the connection between the base 1 and the pile body 2;

[0037] Secondly, when hit by a vehicle, the impact force will directly contact the anti-collision beam 4, and then the anti-collision beam 4 can transmit the impact force in the direction of the spring rod 3, causing the spring rod 3 to shrink and deform, and eliminate part of the impact force. Then the other impact force will act on the connecting rod 5, causing the connecting rod 5 to rotate, and the slider 6 to move outside the slide rod 7, while squeezing the compression spring 8, so that the impact force can be transmitted to the outside, so as to reduce the damage to the base 1 caused by the collision of the vehicle, thereby realizing the protection of the base 1.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
