[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: After the charging pile body is installed, the front of the charging pile body will be aligned with the parking space. At this time, the impact-resistant block can be aligned with the parking space.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging pile technology, specifically to an anti-impact vertical charging pile. Background Technology
[0002] A charging pile is essentially a dedicated power supply device integrating power conversion, metering, billing, control, and communication functions. A vertical charging pile is a type of charging pile specifically designed for outdoor high-power DC fast charging scenarios, featuring a floor-standing EVSE (Electronic Vehicle Escalator). Its characteristics include high integration, high protection level, excellent heat dissipation, and strong scalability. It is the main equipment form for building public charging networks. A vertical charging pile includes the pile body and the power conversion unit installed within it. It is also equipped with a thermal management device to ensure that the heat generated by the power conversion unit during operation is fully dissipated, keeping it in optimal working condition. Vertical charging piles are characterized by high power, high speed, high reliability, ease of maintenance, and strong visibility, and are widely used in various fast-charging parking lots.
[0003] While the aforementioned existing technologies can solve the corresponding technical problems, they still have certain drawbacks: existing vertical charging piles are directly installed on the ground of parking spaces. During use, if the driver's skill level is poor, it is often difficult to control the distance when reversing the vehicle into the parking space. This can easily cause the rear of the vehicle to squeeze and collide with the vertical charging pile, resulting in dents in the outer shell of the charging pile. This not only affects the aesthetics, but the inward-dented outer shell can also compress the internal circuit components, potentially causing short circuits and affecting safety. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing an impact-resistant vertical charging pile that is not easily damaged.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-impact vertical charging pile, comprising a charging pile body and a charging cable disposed on one side of the charging pile body, a heat dissipation device disposed on one side of the charging pile body, and an anti-impact block disposed on the front of the charging pile body.
[0006] A further improvement is that a control panel is also provided on the front of the charging pile body.
[0007] A further improvement is that the bottom of the charging pile body is also equipped with a weighted base.
[0008] A further improvement is that the impact-resistant block includes a deformable buffer block disposed on the front of the charging pile body. The deformable buffer block includes a buffer block body made of silicone material and several deformable airbags embedded in the buffer block body.
[0009] A further improvement is that a connecting channel is provided between several of the deformable airbags.
[0010] A further improvement is that the impact-resistant block also includes a rubber covering layer fixedly installed on the side of the deformation buffer block away from the charging pile body.
[0011] A further improvement is that the impact-resistant block also includes a pressing groove on the front of the charging pile body and several silicone blocks fixedly installed on the inner wall of the pressing groove, with the top of the silicone blocks fixedly connected to one side of the deformation buffer block.
[0012] A further improvement is that the deformable airbag includes a rubber airbag body and a deformable cavity integrally formed within the airbag body.
[0013] A further improvement is that a high-density fiber layer is adhered to the inner wall of the deformable cavity, and elastic fiber filaments are provided between the high-density fiber layers.
[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: After the charging pile body is installed, the front of the charging pile body will be aligned with the parking space. At this time, the impact-resistant block can be aligned with the parking space. When a vehicle enters the parking space and collides with the charging pile body, the vehicle will collide with the impact-resistant block. The resulting squeezing force will cause the deformable airbag to deform rapidly and fully absorb the impact force. At the same time, the entire buffer block body will also be slightly pressed into the pressing groove to further absorb and release the impact force. This avoids excessive squeezing pressure on the charging pile body during vehicle collision, which would cause the charging pile body to deform violently. The impact resistance is stronger, and the electronic components inside the charging pile are less likely to be damaged by impact. Attached Figure Description

Detailed Implementation
[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0018] See Figure 1-4 As shown, the technical solution adopted in this specific embodiment is: an anti-impact vertical charging pile, including a charging pile body 1 and a charging cable 2 disposed on one side of the charging pile body 1. A heat dissipation device 6 is also provided on one side of the charging pile body 1. An impact-resistant block 4 is provided on the front of the charging pile body 1. The impact-resistant block 4 includes a deformable buffer block 43 disposed on the front of the charging pile body 1. The deformable buffer block 43 includes a buffer block body 431 made of silicone material and a plurality of deformable airbags 432 embedded in the buffer block body 431. The buffer block body 431 is made of Shore A material with a hardness of 40°-6. Made of 0° silicone material with a thickness of 50-100mm, the deformable airbag 432 includes a rubber airbag body 51 and a deformable cavity 52 integrally formed within the airbag body 51. In use, first connect the charging pile body 1 to the circuit and install it at the edge of the parking space, with its front facing the parking space. Then, the charging cable 2 can be inserted into the vehicle's charging port for charging. A heat dissipation device 6 ensures the operating temperature of the charging pile body 1. The circuit distribution and specific structure within the charging pile body 1, the heat dissipation device 6, and the charging cable 2 are all... Existing technology, which will not be described in detail here, involves aligning the charging pile body 1 with the parking space after installation. This allows the impact-resistant block 4 to be aligned with the parking space. When a vehicle enters the parking space and collides with the charging pile body 1, the vehicle, typically moving slowly, will not impact the charging pile body 1 at excessive speed. Simultaneously, upon contact, the vehicle will strike the impact-resistant block 4 facing the parking space. The resulting pressure will deform the silicone buffer block body 431, and simultaneously deform the airbag 43. 2 will also be impacted, causing the deformation cavity 52 to contract and deform rapidly. At this time, the impact force can be fully absorbed by the deformation airbag 432 and the silicone buffer block body 431. The deformation airbag 432 is made of natural rubber or neoprene rubber with a wall thickness of 1.5-3mm, which greatly reduces the impact force on the charging pile body 1. This avoids excessive squeezing pressure on the charging pile body 1 during vehicle collision, which would cause the charging pile body 1 to deform violently. It has stronger impact resistance and makes the electronic components inside the charging pile less likely to be damaged by impact. The charging pile body 1 is also equipped with a control panel 5 on the front, which is convenient for controlling the working time and output power of the charging pile body 1 through the control panel 5, making the use of the charging pile more controllable, convenient and intelligent. The bottom of the charging pile body 1 is also equipped with a weighted base 3, which helps to lower the center of gravity of the charging pile body 1, making it more stable and less prone to tipping over when subjected to airflow or external impact. A connecting channel 433 with a diameter of 3-8mm is provided between several deformable airbags 432, so that the air medium in each deformable airbag 432 can circulate with each other and deform together to balance the buffer pressure. When the deformable airbags 432 are subjected to uneven force, the gas in the unidirectional deformable airbag 432 can be guided to other deformable airbags 432 through the connecting channel 433, thereby making its deformation range larger and more fully absorbing the impact force of a smaller range, thus avoiding the bursting of a single deformable airbag 432. The impact-resistant block 4 also includes a rubber cover layer 44 fixedly disposed on the side of the deformable buffer block 43 away from the charging pile body 1. The rubber cover layer 44 is made of wear-resistant rubber with a textured surface, with a Shore A hardness of 60°-80° and a thickness of 5-10mm. This is beneficial to improve the frictional resistance of the contact surface of the impact-resistant block 4 through the high friction coefficient of the rubber material of the rubber cover layer 44, so as to prevent the vehicle from sliding and laterally impacting the charging pile body 1 after contacting the impact-resistant block 4, and at the same time improve the impact absorption limit of the impact-resistant block 4. The impact-resistant block 4 also includes a pressing groove 41 set on the front of the charging pile body 1 and several silicone blocks 42 fixedly set on the inner wall of the pressing groove 41. The top of the silicone block 42 is fixedly connected to one side of the deformable buffer block 43, which is beneficial to the fact that after the deformable buffer block 43 of the impact-resistant block 4 is impacted, it can squeeze the silicone block 42 and be pressed into the pressing groove 41, thereby making the upper limit of impact absorption higher and the protection effect of the charging pile body 1 better. The inner wall of the deformable cavity 52 is also adhered with a high-density fiber layer 53, which is adhered to the inner wall of the deformable cavity 52 by a high-temperature resistant adhesive, and has a basis weight of 200-400g / m². Elastic fiber filaments 54, which are spandex or latex elastic fibers, are also provided between the high-density fiber layers 53. The elastic fiber filaments 54 are in a slightly stretched state in their natural state, and their tensile recovery rate is greater than 85%. This is beneficial for the deformable cavity 52 to recover more quickly after being impacted. At the same time, the elastic fiber filaments 54 and the high-density fiber layer 53 hold the inner wall of the deformable cavity 52 in place, maintaining the shape of the deformable cavity 52 and making it less prone to bulging and other phenomena. To verify the effectiveness of this impact-resistant vertical charging pile, the applicant conducted a simulation test. A charging pile model equipped with the impact-resistant block of this utility model (silicone hardness 50°, airbag wall thickness 2mm) and an ordinary charging pile model were placed in the same position and subjected to an impact from a test trolley with a mass of 1.5 tons at a speed of 5km / h.
[0019] The peak impact force transmitted to the charging pile in the model of a regular charging pile is 12.5kN, and permanent indentations appear on the surface of the pile.
[0020] The peak impact force transmitted to the charging pile by the model of this utility model is only 5.8kN, and the impact force decays by more than 50%. After the external force is removed, the impact-resistant block basically returns to its original shape within 60 seconds, and the charging pile body has no visible deformation. The results show that this utility model can effectively absorb and disperse collision energy through a multi-level buffer energy absorption structure, which greatly reduces the risk of damage to the charging pile body.
[0021] The working principle of this utility model is as follows: When using this utility model, first connect the charging pile body 1 to the circuit and install it at the edge of the parking space, with its front facing the parking space. Then, the charging cable 2 can be inserted into the vehicle's charging port for charging. The heat dissipation device 6 ensures the operating temperature of the charging pile body 1. The circuit distribution and specific structure within the charging pile body 1, the heat dissipation device 6, and the charging cable 2 are all existing technologies and will not be described in detail here. After the charging pile body 1 is installed, align the front of the charging pile body 1 with the parking space. At this time, the anti-impact block 4 can be aligned with the direction of the parking space. When a vehicle enters the parking space and collides with the charging pile body 1, since the vehicle reversing into the parking space is usually moving at a slow speed, even if... Even when a vehicle collides with the charging pile body 1, the impact will not be at an excessively high speed. At the same time, upon contact, the vehicle will collide with the impact-resistant block 4 directly opposite the parking space. The squeezing force generated by the vehicle will cause the silicone buffer block body 431 to deform. Simultaneously, the deformable airbag 432 will also be impacted, causing the deformable cavity 52 to contract and deform rapidly. At this time, the impact force can be fully absorbed through the deformation of the deformable airbag 432 and the silicone buffer block body 431, significantly reducing the impact force on the charging pile body 1. This avoids excessive squeezing pressure on the charging pile body 1 during a vehicle collision, preventing the charging pile body 1 from deforming violently. The impact resistance is stronger, making the electronic components inside the charging pile less susceptible to damage from impacts.
