AI Technical Summary
Existing DC piles can easily cause shell deformation and damage to parts after collision, affect normal use, and may even cause safety accidents.
By installing a fixed assembly on the charging pile base of the DC pile, the elastic block limits it to slide only between the two guide shafts in the mounting hole. When impacted by external forces, the elastic block deforms and slides relative to the guide block. After the external force is cancelled, the elastic block can quickly recover the deformation, thereby reducing the collision between vehicles and pedestrians and DC piles.
It effectively reduces collision between vehicles and pedestrians and DC piles, protects DC piles from damage, improves safety and extends the service life of DC piles.

DETAILED DESCRIPTION
[0024] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0025] like Figure 1-Figure 6 As shown, the anti-collision structure of the DC pile provided in this embodiment includes a charging pile base 1 and an elastic block 2. The charging pile base 1 is fixed on the ground, and the fixing component 3 is fixedly connected to both sides of the upper surface of the charging base. The fixing component 3 includes a fixing plate 4 and a plurality of guide shafts 5. Two mounting holes 6 opened on the front of the fixing plate 4 are used to fix the guide shafts 5. Two guide shafts 5 are fixedly installed in each mounting hole 6. The two ends of each guide shaft 5 are respectively fixedly connected to the upper and lower surfaces of the mounting hole 6. The fixing component 3 is used to limit the elastic block 2 so that the elastic block 2 can only slide between the two guide shafts 5 in the mounting hole 6. The elastic block 2 is an annular structure. The middle ring of the elastic block 2 passes through the four mounting holes 6 and the middle ring of the elastic block 2 is located between the two guide shafts 5. A plurality of guide blocks 11 are provided on the outer surface of the shaft 5, and the inner surfaces of the plurality of guide blocks 11 are rotatably connected to the outer surface of the guide shaft 5. The inner edge of the elastic block 2 contacts the inner guide block 11, and the outer edge of the elastic block 2 contacts the outer guide block 11. When impacted by external force, the elastic block 2 is deformed and slides relative to the guide block 11. After the external force is removed, the elastic block 2 can quickly restore the deformation. Anti-collision columns 7 are fixedly connected to the four corners of the upper surface of the charging pile base 1. A plurality of buffer blocks 8 are provided on the outer surface of the anti-collision column 7. The inner surface of the buffer block 8 is rotatably connected to the outer surface of the anti-collision column 7. When the external force is too large, the impactor hits the elastic block 2 and then continues to hit the buffer block 8. By destroying the buffer block 8 and absorbing energy through the buffer block 8, the charging pile is protected.
[0026] Further, such as Figure 6 As shown, the buffer block 8 is made of porous polyurethane and is hollow inside. A thread 9 is provided on the top of the anti-collision column 7. The thread 9 on the top of the anti-collision column 7 is connected to a baffle 10. The baffle 10 is unscrewed through the thread 9 on the top of the anti-collision column 7. The baffle 10 on the top of the anti-collision column 7 is unscrewed and the buffer block 8 is replaced.
[0027] Furthermore, Figure 1As shown, the outer surface of the buffer block 8 has two colors and both are warning colors. The buffer blocks 8 of the two colors are arranged alternately. The alternating arrangement of the warning colors can be used to remind pedestrians or drivers who are far away, thereby preventing the DC pile from being hit.
[0028] Among them, Figure 4 as well as Figure 5 As shown, the elastic block 2 includes an elastic layer 12 and multiple fixed layers 13. The elastic layer 12 is rubber, and an annular steel bar 14 is wrapped inside the rubber. The fixed layer 13 is non-woven fabric, and a wear-resistant coating 15 is coated on the outside of the non-woven fabric. Both sides of the elastic layer 12 are fixedly connected to the fixed layer 13. The annular steel bar 14 enables the elastic block 2 to withstand greater force when deformed. The non-woven fabric fixes the rubber of the elastic layer 12 and the wear-resistant coating 15. The wear-resistant coating 15 protects the appearance of the elastic block 2 when the elastic block 2 collides with a vehicle or a pedestrian.
[0029] Further, such as Figure 1 As shown, a warning line is provided on the outer surface of the elastic block 2. The warning line has two warning colors and is arranged alternately. The alternating arrangement of the warning colors can be used to remind pedestrians or drivers who are far away, thereby preventing the DC pile from being hit.

When hit by an external force, the elastic block 2 is deformed and the elastic block 2 slides relative to the guide block 11. After the external force is removed, the elastic block 2 can quickly restore the deformation. Anti-collision columns 7 are fixed at the four corners of the upper surface of the charging pile base 1, and a plurality of buffer blocks 8 are arranged on the outer surface of the anti-collision column 7. The inner surface of the buffer block 8 is rotatably connected to the outer surface of the anti-collision column 7. When the external force is too large, the impactor continues to collide with the elastic block 2 after hitting it. The buffer block 8 is hit, and the buffer block 8 is damaged and the energy is absorbed by the buffer block 8 to protect the charging pile. The top of the anti-collision column 7 is provided with a thread 9, and the thread 9 at the top of the anti-collision column 7 is connected with a baffle 10. The baffle 10 is unscrewed through the thread 9 at the top of the anti-collision column 7. The baffle 10 at the top of the anti-collision column 7 is unscrewed, and the buffer block 8 is replaced. The outer surface of the buffer block 8 and the elastic block 2 is a warning color, and the warning color is used to remind pedestrians or drivers who are far away, so as to avoid the DC pile from being hit. The elastic block 2 includes an elastic The elastic layer 12 and multiple fixed layers 13, the elastic layer 12 is rubber, the rubber is wrapped with an annular steel bar 14, the fixed layer 13 is non-woven fabric, the non-woven fabric is coated with a wear-resistant coating 15 on the outside, both sides of the elastic layer 12 are fixedly connected to the fixed layer 13, the annular steel bar 14 enables the elastic block 2 to withstand greater force when deformed, the non-woven fabric fixes the rubber of the elastic layer 12 and the wear-resistant coating 15, and the wear-resistant coating 15 protects the appearance of the elastic block 2 when the elastic block 2 collides with a vehicle or a pedestrian.
[0031] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.
[0032] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
