[0002] A photovoltaic (PV) charging station is a device that uses photovoltaic panels to convert solar energy into electrical energy, thereby providing charging for electric vehicles. Existing PV charging stations are mainly grid-connected, requiring connection to the power grid. This type of charging station is designed to generate electricity using solar energy when there is sufficient sunlight and store the energy in energy storage devices; when sunlight is insufficient or the energy storage devices are running low, it can draw power from the power grid.

[0003] Both photovoltaic charging piles and ordinary charging piles may face the risk of vehicles colliding with the charging pile equipment due to driver error in practical applications. If a charging vehicle accidentally knocks over a charging pile, this situation is very likely to cause the neutral wire and live wire at the input end of the charging pile to come into contact, thereby triggering a short circuit and bringing safety hazards and potential dangers.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] To address the technical problem in existing photovoltaic charging piles where a vehicle collision due to driver error can easily cause a short circuit between the neutral and live wires at the charging pile's input end, posing a danger, this invention provides a protective structure for photovoltaic charging piles that can automatically cut off the power supply to the charging pile before it is impacted, thereby preventing a short circuit and potential danger.

[0028] It should be noted that the protective structure of the photovoltaic charging pile described in this utility model is used in, but not limited to, photovoltaic charging piles. For ease of explanation, this utility model only uses the application of the protective structure of the photovoltaic charging pile in photovoltaic charging pile equipment as an example. The principle of the protective structure of the photovoltaic charging pile applied to other types of equipment is essentially the same as that applied to photovoltaic charging pile equipment, and will not be described in detail here.

[0029] Please see Figures 1-4 , Figure 1 This is a schematic diagram of the protective structure of a photovoltaic charging pile in one embodiment of the present invention. The protective structure of the photovoltaic charging pile includes a charging body 1, a protective mechanism 2, and a power-off mechanism 3.

[0030] The charging main body 1 includes a distribution box 11, a circuit breaker 12, and a charging pile 13. The circuit breaker 12 is fixed inside the distribution box 11. The input terminal of the circuit breaker 12 is used to connect to the power grid, and the output terminal of the circuit breaker 12 is connected to the input terminal of the charging pile 13.

[0031] The protective mechanism 2 includes a protective pile 21, which is located on the side of the charging pile 13 near the charging vehicle parking space.

[0032] The power-off mechanism 3 includes an electric push rod 31, a power supply 32, and a contact switch 33 arranged in series. The fixed end of the electric push rod 31 is fixed inside the distribution box 11, and the movable end of the electric push rod 31 faces the circuit breaker handle 121 of the circuit breaker 12 and abuts against the circuit breaker handle 121. The contact switch 33 is connected to the protective pile 21.

[0033] In the event of an accident, such as a vehicle losing control and crashing into a charging pile, the out-of-control vehicle will first hit the protective pile 21. After the protective pile 21 is displaced by the impact, the contact switch 33 will be triggered, thereby energizing the electric push rod 31. The electric push rod 31 will quickly push the circuit breaker 12's circuit breaker handle 121 to disconnect the circuit, thus effectively avoiding potential safety risks.

[0034] In one embodiment, please refer to Figure 1 and Figure 2 The power-off mechanism 3 further includes a first fixing plate 34, which is fixed inside the distribution box 11, and the fixed end of the electric push rod 31 is fixed to the first fixing plate 34.

[0035] In one embodiment, please refer to Figure 1 and Figure 2The power-off mechanism 3 also includes a second fixing plate 35, which is fixed inside the distribution box 11. The second fixing plate 35 has a limit hole, and the movable end of the electric push rod 31 passes through the limit hole. By setting the limit hole, the movement of the movable end of the electric push rod 31 can be guided, thereby improving the stability of its movement process.

[0036] In one embodiment, please refer to Figures 1-3 The power-off mechanism 3 further includes an elastic element 36, which includes a first push plate 361, a spring 362, and a second push plate 363. The first push plate 361 is fixed to the movable end of the electric push rod 31. The two ends of the spring 362 are respectively fixedly connected to the first push plate 361 and the second push plate 363. The second push plate 363 abuts against the circuit breaker handle 121. By setting the elastic element 36, the impact force on the circuit breaker handle 121 of the circuit breaker 12 can be reduced, preventing damage to the circuit breaker 12.

[0037] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The protective pile 21 is fixed to the ground 4, and a receiving groove 41 is opened on the ground. The side of the protective pile 21 near the charging pile 13 contacts the inner cavity of the receiving groove 41. The contact switch 33 includes a first electrode plate 331, a second electrode plate 332, and a connecting rod 333. The first electrode plate 331 is fixed in the receiving groove 41 and is electrically connected to the positive terminal of the power supply 32. The second electrode plate 332 is fixed to the protective pile 21 via the connecting rod 333. The second electrode plate 332 is spaced apart from the first electrode plate 331 and is located between the first electrode plate 331 and the protective pile 21. The second electrode plate 332 is electrically connected to the positive terminal of the electric push rod 31, and the negative terminal of the electric push rod 31 is electrically connected to the negative terminal of the power supply 32. In use, if an accident occurs, such as a vehicle losing control and crashing into a charging pile, the out-of-control vehicle will first hit the protective pile 21. After the protective pile 21 is displaced by the impact, the second electrode plate 332 moves toward the first electrode plate 331 and comes into contact with the first electrode plate 331, thereby energizing the electric push rod 31. The electric push rod 31 will quickly push the circuit breaker 12's circuit breaker handle 121 to disconnect the circuit, thereby effectively avoiding potential safety risks.

[0038] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4The first electrode plate 331 is electrically connected to the positive terminal of the power supply 32 via a first wire 37. The second electrode plate 332 is electrically connected to the positive terminal of the electric push rod 31 via a second wire 38. The negative terminal of the electric push rod 31 is electrically connected to the negative terminal of the power supply 32 via a third wire 39.

[0039] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The receiving groove 41 is covered with a cover plate 42.

[0041] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail as follows: In use, if an accident occurs, such as a vehicle losing control and crashing into a charging pile, the out-of-control vehicle will first hit the protective pile 21. After the protective pile 21 is displaced by the impact, the second electrode plate 332 moves towards the first electrode plate 331 and comes into contact with the first electrode plate 331, thereby energizing the electric push rod 31. The electric push rod 31 will quickly push the circuit breaker handle 121 of the circuit breaker 12 to disconnect the circuit, thereby effectively avoiding potential safety risks.
