Description

Technical Field

[0001] The utility model belongs to the technical field of new energy charging pile protection, and specifically relates to an anti-collision guardrail for a charging pile. Background Art

[0002] With the rise of new energy vehicles, charging piles can be seen in private parking lots, gas stations and other places. Existing charging piles are usually designed to be floor-standing and are generally configured in parking spaces. At present, wired charging is generally adopted. There is a certain limit on the length of the cable of the charging gun. In order to enable the charging gun to reach the charging port of the vehicle for connection, the driver needs to park the vehicle accurately in the parking space before charging, that is, park it within the circle on the ground of the parking space. This has certain requirements for the driver's operation. For some novice drivers, they may collide with the charging pile during reversing, causing damage to the charging pile. In order to avoid damage to the charging pile, a guardrail will be installed to prevent the vehicle from directly hitting the charging pile.

[0003] Although the existing charging pile guardrail can reduce the possibility of collision of the charging pile, it has no buffering effect or the buffering effect is not obvious, which can easily cause damage to the surface and paint of the car. Utility Model Content

[0004] The utility model provides an anti-collision guardrail for a charging pile, which solves the problem that the existing charging pile guardrail can reduce the possibility of collision of the charging pile, but has no buffering effect or the buffering effect is not obvious, which can easily cause damage to the surface and paint of the car.

[0005] To achieve the above objectives, the utility model provides the following technical solutions: a charging pile anti-collision guardrail comprises a charging pile body, a base is arranged downward on the bottom surface of the charging pile body, a fixing column is fixedly arranged upward on the front end of the top surface of the base, and a total of two fixing columns are arranged, and the two fixing columns are respectively located in front of the left and right sides of the charging pile body, a hydraulic buffer is installed on the top of each of the fixing columns, each of the hydraulic buffer is arranged in a front-to-back direction, and the piston rod end of each of the hydraulic buffer is arranged forward, and an anti-collision plate is arranged in front of the two hydraulic buffers, each of the fixing columns is provided with a through hole, and a supporting guide rod is penetrated and slidably arranged in each of the through holes, each of the supporting guide rods is parallel to the hydraulic buffer and is located directly below the hydraulic buffer, and the front ends of the two supporting guide rods are connected forward to the back of the anti-collision plate, and a compression spring is sleeved on the periphery of each of the supporting guide rods, and each of the compression springs is located between the fixing column and the anti-collision plate.

[0006] The beneficial effects of the utility model are as follows: the anti-collision plate is located at the frontmost side, and the vehicle will first hit the anti-collision plate in the process of constantly approaching the charging pile body, causing it to move backward, and then the anti-collision plate moves backward with the supporting guide rod and squeezes the compression spring. The elastic force generated by the compression of the compression spring has a certain resistance to the car, consumes part of the kinetic energy of the car, and has a preliminary buffering effect. The anti-collision plate continues to move backward and will push the piston rod of the hydraulic buffer halfway, and then the car continues to move backward. It is subject to the double resistance of the compression spring and the hydraulic buffer, which again plays a good buffering effect and completely consumes the residual kinetic energy of the car. Through the above method, not only can the charging pile be prevented from being collided, but also the good buffering effect can be used to greatly avoid the damage to the car surface and paint surface caused by the impact force.

[0007] To prevent the support guide rod from falling off the fixed column;

[0008] As a further improvement of the above technical solution: each of the support guide rods passes through a through hole backwards and is fixed with a limiting block.

[0009] The beneficial effect of this improvement is that the support guide rod can be restricted from falling off from the fixed column by the limit block.

[0010] In order to eliminate the potential safety hazard caused by the rapid backward sliding of the support guide rod and avoid accidental injury to others;

[0011] As a further improvement of the above technical solution: each of the fixed columns is fixed with a protective tube at the outer position of the through hole on the rear side, the protective tube is coaxially arranged with the supporting guide rod, and the inner diameter of the protective tube is larger than the outer diameter of the limit block, and the length of the protective tube is equal to the sliding distance of the supporting guide rod.

[0012] The beneficial effect of this improvement is that the protective tube can cover and protect the supporting guide rod in rapid movement, thereby preventing accidental injury to others during the process of the supporting guide rod sliding backward rapidly.

[0013] To facilitate installation, replacement and maintenance of the anti-collision plate;

[0014] As a further improvement of the above technical solution: the support guide rod is threadedly connected to the anti-collision plate.

[0015] The beneficial effect of this improvement is that the anti-collision plate and the supporting guide rod are connected by threads, so that they are easy to assemble and disassemble. The anti-collision plate is the part that is directly hit and is easily damaged, so it is convenient to disassemble and install, which is also conducive to replacing and repairing the anti-collision plate.

[0016] In order to fix the installation of fixing columns;

[0017] As a further improvement of the above technical solution: a fixing seat is fixed to the bottom end of the fixing column, the fixing column and the fixing seat are connected by welding, and the fixing seat is connected to the base by bolts.

[0018] The beneficial effect of this improvement is that the fixing seat is fixed to the base by bolts, so that the fixing column is also fixed to the base.

[0019] In order to better protect the vehicle;

[0020] As a further improvement of the above technical solution: a protective panel is installed on the front side of the anti-collision plate, the front side of the protective panel protrudes from the front side of the anti-collision plate, and the protective panel is made of polyurethane composite material.

[0021] The beneficial effect of this improvement is that the polyurethane composite material has the advantages of strong elastic strength and excellent wear resistance, so using the protective panel as a protective structure that directly touches the car during a collision can effectively reduce damage to the car surface.

[0022] To facilitate observation of the position of the guardrail when parking at night;

[0023] As a further improvement of the above technical solution: a reflective strip is fixedly installed on the front of the protective panel.

[0024] The beneficial effect of this improvement is that the reflective strip makes it easier to observe the position of the guardrail when parking at night, which is helpful for confirming a suitable parking position and preventing the vehicle from hitting the guardrail.

On the back, each of the support guide rods 6 is sleeved with a compression spring 7, and each of the compression springs 7 is located between the fixed column 3 and the anti-collision plate 5; the anti-collision plate 5 is located at the front side. When the vehicle is constantly approaching the charging pile body 1, it will first hit the anti-collision plate 5, causing it to move backward, and then the anti-collision plate 5 moves backward with the support guide rod 6 and squeezes the compression spring 7. The elastic force generated by the compression of the compression spring 7 has a certain resistance to the car, consuming part of the kinetic energy of the car, and has a preliminary buffering effect. The anti-collision plate 5 continues to move backward and pushes the piston rod of the hydraulic buffer 4 in the middle, and then the car continues to move backward. The double resistance of the compression spring 7 and the hydraulic buffer 4 again plays a good buffering effect, completely consuming the residual kinetic energy of the car, and the above method can not only prevent the charging pile from being collided, but also can avoid the damage to the surface and paint of the car caused by the impact force to a great extent through a good buffering effect. Each of the support guide rods 6 passes through the through hole 301 backward and is fixed with a limiting block 601; the limiting block 601 can prevent the support guide rod 6 from falling off from the fixed column 3. Each of the fixed columns 3 is fixed with a protective tube 8 at the outer position of the through hole 301 on the rear side. The protective tube 8 is coaxially arranged with the support guide rod 6, and the inner diameter of the protective tube 8 is larger than the outer diameter of the limit block 601. The length of the protective tube 8 is equal to the sliding distance of the support guide rod 6. The protective tube 8 can cover and protect the support guide rod 6 in rapid motion to prevent the support guide rod 6 from accidentally injuring others when it slides backward rapidly. The support guide rod 6 is threadedly connected to the anti-collision plate 5. The anti-collision plate 5 and the support guide rod 6 are threadedly connected, so that the assembly is convenient and easy to disassemble. The anti-collision plate 5 is a part that is directly hit and is easy to be damaged. It is convenient to disassemble and install, which is also conducive to the replacement and maintenance of the anti-collision plate 5. The bottom end of the fixed column 3 is fixed with a fixed seat 9. The fixed column 3 and the fixed seat 9 are connected by welding, and the fixed seat 9 is connected to the base 2 by bolts.

The front side of the protective panel 10 protrudes from the front side of the anti-collision plate 5. The protective panel 10 is made of polyurethane composite material; polyurethane composite material has the advantages of strong elastic strength and excellent wear resistance. Therefore, the protective panel 10 is used as a protective structure that directly touches the car during a collision, which can effectively reduce damage to the surface of the car. A reflective strip 11 is fixedly installed in front of the protective panel 10; the reflective strip 11 facilitates the observation of the position of the guardrail when parking at night, which is conducive to confirming the appropriate parking position and preventing the vehicle from hitting the guardrail.

[0036] The working principle and use process of this utility model:

[0037] The anti-collision plate 5 is located at the front side. When the vehicle is constantly approaching the charging pile body 1, it will first hit the anti-collision plate 5 and directly touch the protective panel 10. The polyurethane composite material used in the protective panel 10 has the advantages of strong elastic strength and excellent wear resistance, which can effectively reduce the damage to the surface of the car; the car squeezes the anti-collision plate 5 to make it move backward with the supporting guide rod 6 and squeeze the compression spring 7. The elastic force generated by the compression of the compression spring 7 has a certain resistance to the car, which consumes part of the kinetic energy of the car and has a preliminary buffering effect. The anti-collision plate 5 continues to move backward and will push the piston rod of the hydraulic buffer 4 in the middle. Then, when the car continues to move backward, it will be subject to the double resistance of the compression spring 7 and the hydraulic buffer 4, which has a good re-buffering effect and completely consumes the residual kinetic energy of the car. The protective tube 8 can cover and protect the supporting guide rod 6 in rapid movement to prevent accidental injury to others during the rapid sliding backward of the supporting guide rod 6; when the collision protection is over, the compression spring 7 and the hydraulic buffer 4 will automatically return to their previous state, so that the anti-collision plate 5 and the supporting guide rod 6 return to their initial positions, and the limit block 601 limits the supporting guide rod 6 from falling off from the fixed column 3. After the guardrail is automatically reset, it can continue to be used for protection against the next collision; when parking at night, the position of the guardrail can be observed through the reflective strip 11 to confirm the appropriate parking position; the anti-collision plate 5 and the supporting guide rod 6 are connected by threads, which is convenient for assembly and easy to disassemble. The anti-collision plate 5 is easily damaged as the part that is directly impacted, and it is convenient to disassemble and install, which is also conducive to the replacement and maintenance of the anti-collision plate 5.
