Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, and in particular to a car DC charging pile with high safety. Background Art

[0002] A DC charging station is a device used to charge electric vehicles or other electric devices. It transmits electrical energy to the battery of the electric device via direct current to achieve fast charging. DC charging stations usually have a high charging power and can fully charge the electric device in a shorter time.

[0003] Current DC charging piles are usually installed directly at designated locations, but there are still areas that need improvement. For example: First, due to the lack of protective structures, drivers can easily collide with the charging piles, causing damage to the charging piles.

[0004] In the prior art, a Chinese patent for a DC charging pile (publication number CN212979931U) is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: by setting an installation support, an electric pile body, a crash column, an extension column and an electric lifting rod, the crash column and the extension column are connected to the crash barrier to protect the electric pile body to prevent collision damage, and the electric lifting rod drives the crash barrier to rise and fall to adjust the height, which not only facilitates the safety protection of the electric pile body, but also facilitates the adjustment of the height of the guardrail to meet the protection needs of different heights. However, in this technology, although the electric lifting rod is used to drive the crash barrier to protect the electric pile body, it can block external impact in advance to avoid the charging pile body from being impacted, but the external impact will directly act on the crash barrier and the electric lifting rod, thereby causing greater damage to the electric lifting rod. The direct impact will cause it to deform, and the deformation will make the electric lifting rod unable to be adjusted and no longer provide protection, and thus it cannot be reused, which is not conducive to practical application. Summary of the Invention

[0005] The purpose of the present invention is to provide a highly safe DC charging station for automobiles, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A highly safe DC charging pile for a car comprises a base; a charging pile body is fixedly connected to the top of the base, two fixed columns are symmetrically fixedly connected to the top of the base, fixed rods are symmetrically fixedly connected to both sides of the fixed columns, movable plates are slidably connected to the outer sides of the fixed rods, first springs are sleeved on the outer sides of the fixed rods, a movable frame is fixedly connected between the tops of every two movable plates, a buffer component is provided on one side of the movable plate, the buffer component is used to buffer impacts from the front of the charging pile body, a slide groove is symmetrically opened on one side of the movable frame and extends to the other side, a protective component for protecting against impacts on the side of the charging pile body is provided between the inside of the slide groove, and a plurality of collision frames are fixedly connected to one side of the movable frame.

[0008] By adopting the above technical solution, a movable frame that can slide relative to the fixed rod is provided, and multiple collision-bearing frames are provided, so that the impact from the front of the charging pile body can directly act on the fixed rod, and is buffered by the first spring and the buffer assembly, thereby reducing damage to the fixed rod. After the impact, the fixed rod can be reset by the rebound of the first spring, and can withstand multiple impacts and achieve repeated use.

[0009] A further improvement of the technical solution of the present utility model is that the buffer assembly includes a buffer cylinder, which is fixedly connected to one side of the movable plate, and a piston plate is slidably connected between the inner walls of the buffer cylinder. Both ends of the fixed rod extend into the interior of the buffer cylinder and are fixedly connected to the piston plate, and the buffer cylinder is provided with delayed pressure relief pipes on both sides of the piston plate.

[0010] By adopting the above technical solution, the movable plate can be made to slide relative to the fixed rod in the event of a frontal impact, and the piston plate can be made to slide relative to the buffer cylinder, thereby causing the buffer cylinder to generate positive pressure on one side of the piston plate and negative pressure on the other side, thereby restraining the sliding of the piston plate, that is, restraining the relative sliding of the buffer cylinder and the fixed rod.

[0011] A further improvement of the technical solution of the present utility model is that the protective component includes a sliding rod, which is fixedly connected between the inner walls of the slide groove, and a force-bearing column is slidably connected between the outer sides of each two sliding rods, and a plurality of collision frames are also fixedly connected to one side of the force-bearing column, and a second spring is sleeved on the outer side of the sliding rod.

[0012] With the above technical solution, when the side of the charging pile body is about to be impacted, the impact will first act on the collision frame located at the load-bearing column, causing the load-bearing column to slide inside the slide groove, squeezing the second spring to provide buffering protection.

[0013] A further improvement of the technical solution of the utility model is that a rubber pad is provided on one side of the collision frame.

[0014] The adoption of the above technical solution can reduce the direct physical impact between the car and the crash frame, and reduce the direct damage to the car and the crash frame caused by the impact.

[0015] A further improvement of the technical solution of the present utility model is that heat dissipation windows are provided on both sides of the charging pile body.

[0016] The above technical solution is adopted to facilitate heat dissipation of the charging pile body, thereby preventing safety hazards caused by heat accumulation inside the charging pile body.

[0017] A further improvement of the technical solution of the present utility model is that a rain shelter is fixedly connected to the top of the charging pile body.

[0018] By adopting the above technical solution, the main body of the charging pile installed outdoors can provide rain protection, preventing rainwater from seeping into the charging head and causing safety hazards.

[0019] A further improvement of the technical solution of the present utility model is that the inner wall of the movable frame is frosted, and the outer side of the load-bearing column and the contact portion with the movable frame are also frosted.

[0020] By adopting the above technical solution, the relative sliding of the load-bearing column and the slide groove can be hindered by the frosting between the two, thereby achieving buffering.

[0021] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0022] 1. The utility model provides a highly safe DC charging pile for automobiles. By providing a movable frame that can slide relative to a fixed rod and providing a plurality of collision-bearing frames, the impact from the front of the charging pile body can directly act on the fixed rod and be buffered by the first spring and the buffer assembly, thereby reducing damage to the fixed rod. After the impact, the rod can be reset by the rebound of the first spring, thereby being able to withstand multiple impacts and achieve repeated use, thereby greatly improving the service life of the charging pile body and the protective structure.

[0023] 2. The utility model provides a highly safe automobile DC charging pile. By arranging a buffer cylinder, the movable plate can slide relative to the fixed rod in the event of a frontal impact, and the piston plate can slide relative to the buffer cylinder, so that the buffer cylinder generates positive pressure on one side of the piston plate and negative pressure on the other side, thereby restraining the sliding of the piston plate, that is, restraining the relative sliding of the buffer cylinder and the fixed rod, and slowly releasing the pressure through a delayed pressure relief pipe with a smaller aperture, so that the fixed rod slowly slides relative to the movable plate, and cooperates with the first spring to complete the protection against frontal impact, further improving the safety of the charging pile body.

[0035] Example 2

[0036] like Figure 4 and Figure 5 As shown, based on Example 1, the utility model provides a technical solution: preferably, the buffer assembly includes a buffer cylinder 7, the buffer cylinder 7 is fixedly connected to one side of the movable plate 5, and a piston plate 9 is slidably connected between the inner walls of the buffer cylinder 7. Both ends of the fixed rod 4 extend to the interior of the buffer cylinder 7 and are fixedly connected to the piston plate 9. The buffer cylinder 7 is provided with a delayed pressure relief pipe 8 on both sides of the piston plate 9.

[0037] In this embodiment, the movable plate 5 can slide relative to the fixed rod 4 and the piston plate 9 can slide relative to the buffer cylinder 7 in the event of a frontal impact, thereby causing the buffer cylinder 7 to generate positive pressure on one side of the piston plate 9 and negative pressure on the other side, thereby restraining the piston plate 9 from sliding, that is, restraining the relative sliding of the buffer cylinder 7 and the fixed rod 4, and slowly releasing the pressure through the delayed pressure relief pipe 8 with a smaller aperture, so that the fixed rod 4 slowly slides relative to the movable plate 5, and cooperates with the first spring 6 to complete the protection against frontal impact.

[0038] Example 3

[0039] like Figure 1 and Figure 2 As shown, based on Example 1, the utility model provides a technical solution: preferably, the protective component includes a sliding rod 13, the sliding rod 13 is fixedly connected between the inner walls of the slide groove 12, and a force column 17 is slidably connected between the outer sides of each two sliding rods 13, and a plurality of collision frames 10 are also fixedly connected to one side of the force column 17, and a second spring 14 is sleeved on the outer side of the sliding rod 13.

[0040] In this embodiment, when the side of the charging pile body 2 is about to be impacted, the impact will first act on the collision frame 10 located at the load-bearing column 17, thereby causing the load-bearing column 17 to slide inside the slide groove 12, squeezing the second spring 14 to provide buffering protection.

[0041] Preferably, a rubber pad is provided on one side of the collision frame 10 .

[0042] In this embodiment, the direct physical impact between the automobile and the crash frame 10 can be reduced, thereby reducing direct damage to the automobile and the crash frame 10 caused by the impact.

[0049] The following is a detailed description of the working principle of this highly safe DC charging station for cars.

[0050] like Figure 1-5 As shown, when the charging pile body 2 is about to be impacted from the front, the impact first acts on the collision frame 10 on one side of the movable frame 11, so that the collision frame 10 and the movable frame 11 move synchronously and drive the movable plate 5 to slide on the fixed rod 4, while squeezing the first spring 6 to provide preliminary buffering. At the same time, the sliding of the movable plate 5 relative to the fixed rod 4 will cause the piston plate 9 to slide relative to the buffer cylinder 7, thereby causing the buffer cylinder 7 to generate positive pressure on one side of the piston plate 9 and negative pressure on the other side, thereby restraining the sliding of the piston plate 9, that is, restraining the relative sliding of the buffer cylinder 7 and the fixed rod 4, and slowly releasing the pressure through the delayed pressure relief pipe 8 with a smaller aperture, so that the fixed rod 4 slowly slides relative to the movable plate 5, and cooperates with the first spring 6 to complete the protection against frontal impact;

[0051] When the side of the charging pile body 2 is about to be impacted, the impact will first act on the collision frame 10 located at the load-bearing column 17, thereby causing the load-bearing column 17 to slide inside the slide groove 12, squeezing the second spring 14, and at the same time relying on the frosting between the load-bearing column 17 and the slide groove 12 to hinder the relative sliding of the two, thereby achieving buffering to protect the charging pile body 2 from side impacts, and being able to reset under the rebound of the first spring after the impact, thereby being able to withstand multiple impacts and achieve repeated use, greatly improving the service life of the charging pile body and the protective structure.

[0052] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
