[0002] A charging pile refers to a charging device that provides energy replenishment for electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or on the 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 charging operations and print cost data. The charging pile display can display data such as charging capacity, cost, and charging time.

[0003] However, with existing energy storage charging piles, when most cars are in use, they often need to reverse and face the rear of the car toward the charging pile for charging. When the car is reversing, due to the blind spot, the rear of the car is likely to hit the charging pile, causing damage to the equipment and making it unable to be used normally. Therefore, there is a special need for an energy storage charging pile with strong impact resistance. Utility Model Content

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] See also Figure 1-Figure 4 As shown, the utility model provides a technical solution: an energy storage charging pile with strong impact resistance, comprising a base 1, a connecting column 2 and a charging box 3, the connecting column 2 is fixedly connected to the outer wall of the base 1, the charging box 3 is fixedly connected to the top outer wall of the connecting column 2, a protective component 4 is arranged on the outer wall of the connecting column 2, and a buffer component 5 is arranged on the outer wall of the connecting column 2;

[0025] The protective component 4 includes a buffer sleeve 401, a fixing part 402, a spring sheet 403 and a rubber strip 404. The buffer sleeve 401 is fixedly connected to the outer wall of the connecting column 2, and the fixing part 402 for fixing the spring sheet 403 is fixedly connected to the outer wall of the connecting column 2. The rubber strip 404 is fixedly connected to the inner wall of the spring sheet 403. First, the charging pile is fixed at a specified position. When the charging pile is hit, the buffer sleeve 401 is hit and concave inward and squeezes the spring sheet 403. The spring sheet 403 is affected by external force and expands outward on both sides, and the middle part shrinks inward and squeezes the rubber strip 404. The rubber strip 404 can offset a part of the impact force on the connecting column 2 during the process of being squeezed and contracted, and can also protect the connecting column 2, so that when the connecting column 2 is hit, the degree of surface damage is minimized.

[0026] In this embodiment, the buffer sleeve 401 is made of carbon fiber material. The design of the buffer sleeve 401 makes the buffer sleeve 401 flexible, wear-resistant, chemical-resistant and high-temperature-resistant, thereby ensuring the service life of the buffer sleeve 401.

[0027] In this embodiment, the spring sheet 403 is symmetrically arranged with respect to the central axis of the connecting column 2, and the rubber strip 404 is made of a polymer silicone rubber material. Silicone rubber is a polymer material with good heat resistance, cold resistance, and oxidation resistance, and can return to its original shape after being deformed to a certain extent.

[0028] In this embodiment, the buffer component 5 includes a slide groove 501, a first contact 502, a spring 503, a slider 504, and a second contact 505. The outer wall of the connecting column 2 is provided with a slide groove 501, the inner wall of the slide groove 501 is bonded with the first contact 502, the inner wall of the slide groove 501 is fixedly connected with a spring 503, a slider 504 is fixedly connected with the outer wall of one end of the spring 503, and the slider 504 is slidably connected to the slide groove 501, and the outer wall of the slider 504 is bonded with the second contact 505. The buffer sleeve 401 is concave inwardly when impacted and When the slider 504 is squeezed, the slider 504 slides toward the inside of the slide groove 501 and squeezes the spring 503 due to the external force. When the slider 504 slides toward the inside of the slide groove 501, the first contact 502 contacts the second contact 505 and generates friction. When the limit slider 504 slides toward the inside of the slide groove 501, the spring 503 is squeezed and contracts inwardly, which generates an outward thrust. When the slider 504 slides into the slide groove 501, the thrust generated by the spring 503 pushes the slider 504 and the car, thereby offsetting part of the impact force of the car on the connecting column 2.

[0029] In this embodiment, the first contact 502 is symmetrically arranged with respect to the central axis of the slide groove 501, and the second contact 505 is symmetrically arranged with respect to the central axis of the slider 504, and both the first contact 502 and the second contact 505 are made of rubber material. The design of the first contact 502 and the second contact 505 can increase the force required for the slider 504 to slide into the slide groove 501 through the friction force generated when the first contact 502 and the second contact 505 contact each other, thereby offsetting a part of the impact force of the car on the connecting column 2.

[0030] In this embodiment, the distance between the bottom outer wall of the charging box 3 and the top outer wall of the base 1 is greater than 1.6 meters. The height of a family car is generally between 1.4 meters and 1.6 meters. The distance between the charging box 3 and the base 1 is greater than 1.6 meters, which can prevent the charging box 3 from being damaged by the impact when the car hits the charging pile.

[0031] Working principle: First, fix the charging pile at the designated position. When the charging pile is hit, the buffer sleeve 401 is hit and dents inward and squeezes the spring sheet 403. The spring sheet 403 is affected by the external force and expands outward on both sides, and the middle part shrinks inward and squeezes the rubber strip 404. The rubber strip 404 can offset a part of the impact force on the connecting column 2 during the process of being squeezed and contracted. At the same time, when the buffer sleeve 401 is hit and dents inward and squeezes the slider 504, the slider 504 slides into the inside of the slide groove 501 and squeezes the spring 503. The slider 504 moves When the slider 504 slides inside the slide groove 501, the first contact 502 will contact the second contact 505 and generate friction, which can increase the force required for the slider 504 to slide into the slide groove 501. When the spring 503 is squeezed and contracts inward, it will generate an outward thrust, so that the slider 504 slides into the slide groove 501. At the same time, the thrust generated by the spring 503 will push the slider 504 and the car, which can offset a part of the impact force of the car on the connecting column 2, thereby minimizing the impact force on the charging box, thereby completing the use process of a highly impact-resistant energy storage charging pile.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
