[0017] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0018] The following will be combined with the instructions attached Figure 1-2 And specific implementation methods are used to describe the above technical solutions in detail:

[0019] The utility model provides a split DC charging pile, comprising a charger 1 and a charging pile 2, the charger 1 and the charging pile 2 are connected by a cable, and protective structures are respectively arranged on the charger 1 and the charging pile 2, the protective structure comprising a mounting block 3 fixedly connected to the charger 1 and the charging pile 2 respectively, a sliding groove 4 is opened inwardly from the outer side of the mounting block 3, a stopper is fixedly connected at the notch of the sliding groove 4, a sliding rod 5 is arranged in the sliding groove 4, one side of the sliding rod 5 is located on the outer side of the mounting block 3, a piston 6 slidably connected to the sliding groove 4 is fixedly connected to the inner side of the sliding rod 5, an inert gas is filled between the piston 6 and the sliding groove 4, a protective plate 7 is fixedly connected to the outer side of the sliding rod 5, and a buffer layer 8 is wrapped on the outer side of the protective plate 7. After the installation is completed, if a vehicle hits the charger 1 or the charging pile 2, the vehicle will first collide with the protective plate 7, and the buffer layer 8 on the protective plate 7 will first absorb part of the kinetic energy to reduce the vibration caused by the impact. Then, the impact on the protective plate 7 will drive the sliding rod 5 to move into the sliding groove 4, thereby driving the piston 6 to move. As the piston 6 moves, since the space between the piston 6 and the sliding groove 4 is filled with inert gas, the inert gas and the piston 6 can be regarded as a gas spring, which continues to absorb kinetic energy and further reduces the vibration caused by the impact. It can prevent the vehicle from directly hitting the charger 1 and the charging pile 2, causing damage and affecting the use, and it can also reduce the impact and damage of the kinetic energy generated by the impact on the charger 1 and the charging pile 2. Preferably, the protective structure can be respectively arranged on the remaining surfaces except the opposite side of the charger 1 and the charging pile 2.

[0020] In order to further absorb kinetic energy and mitigate the damage to the charger 1 and the charging pile 2 caused by vibration caused by the impact, as a preferred embodiment, a plurality of springs 9 are arranged between the side of the piston 6 away from the sliding rod 5 and the sliding groove 4, and the two ends of the spring 9 are respectively fixedly connected to the piston 6 and the bottom of the sliding groove 4, and a damper is arranged at the connecting end of the spring 9. When the piston 6 moves, the spring 9 is squeezed and deformed, and the elastic potential energy generated when the spring 9 is compressed can offset part of the vibration caused by the impact, thereby enhancing the buffering effect.

[0021] As a preferred embodiment, an airbag 10 is fixedly connected to the outer side of the sliding rod 5, and a ventilation groove 11 is opened upwardly between the sliding groove 4 and the piston 6. The airbag 10 is connected to the ventilation groove 11 through a hose 12, and the connection of the hose 12 is sealed. When the piston 6 moves, the piston 6 will squeeze the inert gas, so that the inert gas enters the airbag 10 through the hose 12, so that the airbag 10 expands and expands, thereby preventing the protective plate 7 from continuing to move, and can also absorb the kinetic energy generated by the impact, further enhancing the buffering effect.

[0022] In order to allow the airbag 10 to expand and deploy normally, as a preferred embodiment, the volume of the inert gas in the sliding groove 4 is greater than the minimum volume of gas required for the deployment of the airbag 10 .

[0023] As a preferred embodiment, the protective plate 7 is a polyethylene plate. The protective plate 7 made of polyethylene has excellent wear resistance and impact resistance.

[0024] Due to the different heights of the vehicles, the impact angles may be different. As a preferred embodiment, the protective plate 7 is an inwardly curved arc plate.

[0025] As a preferred embodiment, the buffer layer 8 is a foam rubber layer. The foam rubber material has excellent buffering performance: the porosity of the foam rubber is usually between 50% and 98%, which can effectively reduce vibration and impact.

[0026] Preferably, the standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings.
