Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a protection device for charging piles in a parking lot. Background Art

[0002] A charging pile is a device that provides electric vehicles with energy. Its function 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 (charging stations, shopping malls, public parking lots, etc.) and parking lots in residential areas. It can charge various types of electric vehicles according to the voltage and current. 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] After searching, the Chinese utility model with announcement number CN211943004U discloses a parking lot charging pile anti-collision protection device, including a bottom plate, a fixing plate is installed on the top of the bottom plate by bolts, and a reinforcing rib is welded between the fixing plate and the bottom plate, a spring is welded on one side of the fixing plate, and a baffle is welded on one end of the spring, and a protective cover is arranged on the periphery of the baffle, a fixing rod is welded on one side of the top of the bottom plate, and an LED energy-saving lamp is installed on the top of the fixing rod by bolts, a bearing plate is installed on the top of one side of the fixing rod by bolts, and an infrared induction lamp is installed on the bottom side of the bearing plate by bolts. This utility model is a parking lot charging pile anti-collision protection device, which has a reasonable structure and is easy to use, and is suitable for being widely promoted and used.

[0004] However, the above patent has the following shortcomings: the above device uses the buffering ability of the spring to achieve the anti-collision function. If the car moves backward at too fast a speed, in order to prevent the car from hitting the charging pile, a larger elastic potential energy is required to offset it. However, the basic elasticity of the spring of the above device cannot be adjusted, and the car can continue to move backward, thereby hitting the charging pile. Summary of the invention

[0022] Second, in the present invention, when the car moves backward excessively, the rear end of the car contacts the force belt, the force belt is arched, and the winding roller is pulled by the force belt to rotate. When the winding roller rotates, the rotating column on the winding roller rotates accordingly, and the damping mechanism applies reverse damping, so that the force belt has a tightening tendency, thereby resisting the backward movement force of the car. The driver can feel obvious resistance and thus perform emergency braking. The flexible braking method can better protect the car.

[0023] Thirdly, in the present invention, the rotating column rotates, and the force transmission plate on the rotating column rotates accordingly. The force transmission plate pulls the piston rod out of the piston cylinder with the help of the second rotating block. The piston cylinder generates negative pressure, and the piston cylinder draws the damping oil in the liquid storage tank into the piston cylinder. At the same time, the first spring is stretched to generate a counter force, and the main gear on the rotating column rotates accordingly. The main gear moves the gate plate downward through the gear, and the gate plate reduces the aperture of the first through pipe, hindering the flow of the damping fluid, thereby increasing the damping. That is, during the backward movement of the impact force of the car, the damping increases accordingly, so that the car brakes faster and the driver can feel it more obviously, thereby performing the braking operation.
