Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging pile technology, and in particular to a collision-proof vertical DC charging pile. Background Technology
[0002] With the increasing popularity of electric vehicles, charging stations, as an important supporting facility, have received significant attention for their safety and reliability. However, in actual use, charging stations often face the risk of collisions caused by vehicle misoperation or driving errors. Especially in densely populated areas such as parking lots and charging stations, charging stations are prone to becoming targets of collisions. Once a collision occurs, it can not only damage the charging station itself but also pose safety hazards to vehicles and people.
[0003] Currently, most charging stations on the market are fixed installations and lack effective collision protection designs. Although some charging stations have added guardrails or crash barriers at the parking space location, these structures usually only provide limited protection and cannot effectively absorb collision energy or prevent direct damage to the charging station. Furthermore, the structures of guardrails or crash barriers are mostly rigid, which can only protect the charging station itself in the event of a collision, but cannot reduce damage to the vehicle. Therefore, existing collision-proof charging stations still have certain shortcomings in use. Utility Model Content
[0004] The purpose of this invention is to solve the problem of poor anti-collision effect of the above-mentioned traditional charging pile anti-collision structure, and to provide a collision-proof vertical DC charging pile with the advantages of strong buffering ability of collision force, ability to restrict vehicle movement to prevent secondary collision, and better protection effect.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A collision-resistant vertical DC charging pile includes a charging pile body. The bottom of the charging pile body is installed on the ground via a pre-embedded base. A second barrier and a first barrier are arranged sequentially from near to far in front of the charging pile body. The first barrier and the second barrier are used to secure the wheels of the charging vehicle. The first barrier is installed in a mounting groove in the ground and can retract into the mounting groove when the top of the first barrier is subjected to pressure. A shock-absorbing linkage mechanism is installed between the second barrier and the charging pile body. The shock-absorbing linkage mechanism is used to push the charging pile body away from the pre-embedded base when subjected to thrust.
[0007] Preferably, the first barrier includes a lifting guardrail, and the side of the lifting guardrail away from the second barrier is provided with a slope.
[0008] Preferably, a return spring is installed inside the mounting groove, and the return spring is connected to the bottom of the lifting guardrail.
[0009] Preferably, the top height of the second barrier is slightly higher than the top height of the first barrier when it is raised to its highest point.
[0010] Preferably, the shock absorption linkage mechanism includes an anti-collision push plate and a guide rod. The anti-collision push plate is slidably mounted on the guide rod, and the guide rod is connected between the second barrier and the pre-embedded base. A buffer pad is provided on the charging pile body. When the anti-collision push plate is pushed and moves, the push force is transmitted to the charging pile body through the buffer pad.
[0011] Preferably, the guide rod includes a first guide rod and a second guide rod arranged in parallel, and a first buffer spring is installed on the first guide rod, which is compressed when the anti-collision push plate is pushed and moves.
[0012] Preferably, a sliding rail is provided on the top of the pre-embedded base, the charging pile body is slidably connected to the sliding rail, a support beam is provided at the end of the pre-embedded base away from the second barrier, and a second buffer spring is installed between the support beam and the charging pile body.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. By setting up the first and second barriers, the system can not only prevent collisions but also secure the vehicle wheels, further preventing secondary collisions with the charging pile itself. This results in better collision protection and will not damage the vehicle.
[0015] 2. By setting up a shock-absorbing linkage mechanism, a collision-resistant push plate is added to prevent the vehicle from colliding with the charging pile body. When the vehicle collides with the collision-resistant push plate, the first buffer spring plays a buffering role. When the collision force and collision displacement are large, the charging pile body can also further collapse, and the second buffer spring will provide secondary buffering of the collision force, which greatly increases the anti-collision capability. Moreover, the shock-absorbing linkage mechanism can also reduce the damage to the vehicle when buffering the collision force. Attached Figure Description

Detailed Implementation
[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] like Figure 1 As shown, a collision-proof vertical DC charging pile includes a charging pile body 1. The bottom of the charging pile body 1 is installed on the ground through a pre-embedded base 2. The pre-embedded base 2 serves to support the charging pile body 1, raises the charging pile body 1 to make it waterproof, and can also connect the internal wiring of the charging pile body 1 to the high-voltage power grid.
[0023] like Figure 1 As shown, a second barrier 4 and a first barrier 3 are arranged sequentially from near to far in front of the charging pile body 1. The first barrier 3 and the second barrier 4 are used to secure the wheels of the charging vehicle. The first barrier 3 is installed in an installation groove 8 opened in the ground, so that the installation groove 8 can be retracted when the top of the first barrier 3 is subjected to pressure. A shock-absorbing linkage mechanism 5 is installed between the second barrier 4 and the charging pile body 1. The shock-absorbing linkage mechanism 5 is used to push the charging pile body 1 and the pre-embedded base 2 away from the second barrier 4 when subjected to thrust. The first barrier 3 serves as the first layer of collision protection, primarily preventing the wheels from hitting the rear of the vehicle against the charging pile 1. To avoid damaging the vehicle's chassis, the height of the first barrier 3 is typically no higher than the chassis height. However, in the event of vehicle loss of control, excessive speed can cause the wheels to pass over the top of the first barrier 3. When the first barrier 3 is subjected to pressure from the top, it is pressed into the mounting groove 8. At this point, the wheel enters between the first barrier 3 and the second barrier 4. The first barrier 3 is recessed to prevent wheel deviation. If the wheel is lifted by the first barrier 3 when it runs over it, the landing point of the wheel is easily deviated, preventing the wheel from accurately landing between the two barriers, thus affecting its wheel-restricting effect. Figure 2As shown, the effect of locking the wheel between the first barrier 3 and the second barrier 4 serves as the second anti-collision barrier. In extreme cases, if the wheel continues to move backward, the vehicle body will come into contact with the shock absorption linkage mechanism 5. In order to prevent the vehicle body from hitting the charging pile body 1, the charging pile body 1 can move relative to the pre-embedded base 2 at this time, and the charging pile body 1 moves backward a certain distance. This operation position serves as the third anti-collision barrier. By using these three anti-collision barriers, the accident rate of the charging pile body 1 is greatly reduced.
[0024] like Figure 3 As shown, the first barrier 3 includes a rising guardrail 6. A ramp 7 is provided on the side of the rising guardrail 6 away from the second barrier 4. The purpose of the ramp 7 is to ensure that while the first barrier 3 acts as a barrier, the wheels can still pass over the top of the rising guardrail 6 as the vehicle continues to move. The ramp 7 also serves a guiding function. Because the bottom of the rising guardrail 6 extends into the mounting groove 8, when the wheel pushes the rising guardrail 6 horizontally, the rising guardrail 6 experiences a horizontal thrust and will not easily retract, thus avoiding affecting its blocking effect. A return spring 9 is installed inside the mounting groove. The return spring 9 is connected to the bottom of the rising guardrail 6. The return spring 9 supports the rising guardrail 6 and can also return to its original position after the pressure is released when the rising guardrail 6 is compressed into the mounting groove 8. The top height of the second barrier 4 is slightly higher than the top height of the first barrier 3 when it is raised to its highest point. The heights of both the first barrier 3 and the second barrier 4 do not exceed the chassis height of a normal vehicle. The reason why the second barrier 4 is slightly higher is to prevent the wheel from running over the second barrier 4 again after it has run over the first barrier 3.
[0025] like Figure 4 As shown, the shock absorption linkage mechanism 5 includes a crash barrier 13 and a guide rod. The crash barrier 13 is slidably mounted on the guide rod, which is connected between the second barrier 4 and the pre-embedded base 2. A buffer pad 14 is provided on the charging pile body 1. When the crash barrier 13 is pushed and moves, the push force is transmitted to the charging pile body 1 through the buffer pad 14. The shock absorption linkage mechanism 5 acts as the final anti-collision insurance, using the crash barrier 13 to buffer the collision force of the vehicle. The crash barrier 13 does not rely mainly on its own material for anti-collision, but rather on the displacement on the guide rod when it is pushed to dissipate the force until it contacts the buffer pad 14. The buffer pad 14 also has the effect of dissipating the force. Finally, if the vehicle body continues to push the crash barrier 13 to move, the push force will push the charging pile body 1 backward for the final anti-collision buffer. By using the three anti-collision methods of limiting the wheels between the first barrier 3 and the second barrier 4, and the force dissipation of the shock absorption linkage mechanism 5, the probability of the charging pile body 1 being damaged by a collision can be reduced layer by layer.
[0026] The guide rods not only serve a guiding function but also need to buffer the impact force on the anti-collision push plate 13. The guide rods include a first guide rod 10 and a second guide rod 11 arranged in parallel. A first buffer spring 12 is installed on the first guide rod 10. When the anti-collision push plate 13 is pushed and moved, the first buffer spring 12 is compressed. The second guide rod 11 and the first guide rod 10 make the translation of the anti-collision push plate 13 more stable. The first buffer spring 12 is installed on the first guide rod 10 to make the anti-collision push plate 13 have an anti-collision buffering effect. A sliding rail 15 is set on the top of the pre-embedded base 2. The charging pile body 1 is slidably connected to the sliding rail 15. A support beam 16 is set on the end of the pre-embedded base 2 away from the second barrier 4. A second buffer spring 17 is installed between the support beam 16 and the charging pile body 1. The sliding rail 15 makes the movement of the charging pile body 1 more stable. The second buffer spring 17 can reset the charging pile body 1 after it moves backward and buffer it during the backward movement, which greatly improves the anti-collision effect of the last layer of the shock absorption linkage mechanism 5.
