[0028] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0029] Example 1

[0030] like Figure 1 As shown, one embodiment of the present invention proposes a cold charging pile with an anti-collision buffer, comprising: a liquid cooling heat dissipation mechanism located at the rear end of the charging pile body 1, and an alarm device and a buffer device located at the front end of the charging pile body 1. The alarm device includes an alarm 2 and an infrared sensor 3 for ranging. During use, the liquid cooling heat dissipation mechanism facilitates cyclic heat dissipation of the charging pile body 1.

[0031] When a vehicle is charging, an infrared sensor 3 detects the distance between the vehicle and the charging station body 1. When a vehicle approaches the charging station body 1, an alarm 2 sounds, reminding personnel to maintain distance. The infrared sensor 3 is located above the mounting bracket to prevent it from blocking the infrared sensor signal. The alarm 2 is also located above the infrared sensor 3 and positioned high, minimizing the risk of the vehicle blocking the alarm sound when it sounds.

[0032] like Figure 2As shown, the buffer device includes a fixed frame, a buffer block 13, a movable rod 10 and an adjusting unit. The fixed frame is fixed to the front end of the charging pile body 1, one end of the movable rod 10 is plugged into the fixed frame, the buffer block 13 is installed at the other end of the movable rod 10, and a first spring 12 is sleeved on the movable rod 10; the adjusting unit is symmetrically installed on the left and right sides of the movable rod 10, and the adjusting unit includes a connecting rod 11 and a movable sleeve 6 and a U-shaped sleeve 7 slidably installed on the fixed frame, the movable sleeve 6 can be locked on the fixed frame, and a second spring 9 is arranged between the U-shaped sleeve 7 and the movable sleeve 6, and the two ends of the connecting rod 11 are rotatably connected to the U-shaped sleeve 7 and the movable rod 10 respectively. The fixed frame includes a fixed plate 4 and a slide rail 5. The fixed plate 4 and the slide rail 5 form a U-shaped structure. The fixed plate 4 has two pieces. The two fixed plates 4 are respectively fixed on the left and right sides of the charging pile body 1. The slide rail 5 is located at the front end of the charging pile body 1. The two ends of the slide rail 5 are connected to the fixed rods at both ends. The movable sleeve 6 and the U-shaped sleeve are both slidably installed on the slide rail 5.

[0033] When the vehicle continues to move backward, the rear of the vehicle contacts the buffer block 13, and drives the movable rod 10 to slide and compress the first spring 12, thereby achieving the purpose of preliminary buffering of the collision. At the same time, the connecting rod 11 rotates, driving the two U-shaped sleeves 7 to move relatively away from the surface of the slide rail 5 to squeeze the second spring 9. Therefore, through the elastic potential energy of the infrared sensor 3, the alarm 2, the second spring 9 and the first spring 12, the driver is reminded and double buffered, avoiding unnecessary damage to the charging pile body 1 and the vehicle caused by vehicle collision. By adjusting the position of the movable sleeve 6 on the slide rail, and then adjusting the squeezing of the movable sleeve 6 on the second spring 9, the range of motion of the second spring 9 is reduced, thereby enhancing the elastic potential energy and buffering strength of the second spring 9, effectively improving the service life, buffering effect and flexibility of the charging pile body.

[0034] like Figure 2 As shown, the adjustment unit further includes a limiting rod 8, one end of which is fixed to the end of the movable sleeve 6 facing the U-shaped sleeve 7, and the other end of the limiting rod 8 is provided with a limiting flange. The second spring 9 and the U-shaped sleeve 7 are both sleeved on the limiting rod 8. The provision of the limiting rod facilitates the installation of the second spring, and the provision of the limiting flange on the inner end of the limiting rod prevents the U-shaped sleeve from detaching from the limiting rod under the action of the second spring.

[0035] The movable sleeve 6 is locked on the fixing frame by a locking member. The locking member is composed of a screw hole opened on one side of the movable sleeve 6 and a hand screw 14 threadedly installed in the screw hole. The inner end of the hand screw 14 abuts against the fixing frame.

[0036] Specifically, by loosening the hand-tightening bolt 14, the movable sleeve 6 is moved along the surface of the slide rail 5 toward the U-shaped sleeve 7, and the limiting rod 8 is driven to slide, thereby achieving the purpose of squeezing the second spring 9, and then tightening the hand-tightening bolt 14 to fix the movable sleeve 6, thereby achieving the effect of adjusting the elastic force of the second spring 9, facilitating the subsequent adjustment of the elastic potential energy of the second spring 9, and improving the flexibility of use.

[0037] like Figure 3 、 Figure 4 As shown, the liquid cooling heat dissipation mechanism includes a cooling coil 15 fixedly mounted within the charging pile body 1, a water tank 16 fixedly mounted on the rear surface of the charging pile body 1, a water pipe 17 fixedly mounted at the bottom of one side of the water tank 16, and a water pump 18 fixedly mounted at the top of one side of the water tank 16. The water tank 16 is provided with a refrigeration mechanism. The cooling coil 15 is made of copper or other heat-conducting materials and contacts the heat-generating components within the charging pile body 1. A water injection pipe is fixedly mounted at the top of the water tank 16, and a sealing cap is provided at the end of the water injection pipe.

[0038] One end of the water pipe 17 passes through the charging pile body 1 and is connected to one end of the cooling coil 15. The output end of the water pump 18 passes through the charging pile body 1 and is connected to the other end of the cooling coil 15 via a pipe. The input end of the water pump 18 extends into the water tank 16. The water pump 18 is electrically connected to the control components in the charging pile body 1.

[0039] When the charging pile body 1 is dissipating heat, the coolant in the water tank 16 is input into the cooling coil 15 through the water pipe 17 for heat exchange, and the coolant is extracted by the water pump 18 and returned to the water tank 16 again. The coolant after heat exchange is cooled by the refrigeration mechanism, and the cycle is repeated to achieve the effect of circulating liquid cooling and heat dissipation.

[0040] like Figure 3 As shown, the cooling mechanism includes a heat sink 19 fixedly mounted in the water tank 16, a cooler 20 fixedly mounted on the top of the water tank 16, and a heat pipe 21 fixedly connected to the cooling end of the cooler 20. The bottom end of the heat pipe 21 passes through the water tank 16 and connects to the heat sink 19. The cooler 20 is electrically connected to the control components in the charging pile body 1. The cooler 20 is a semiconductor cooler with a heat dissipation structure at its heating end. The heat pipe 21 is made of copper or other thermally conductive materials.

[0041] The cooling is performed through the cooling end of the refrigerator 20, and the cooling capacity is transferred to the heat sink 19 through the heat pipe 21, and the heat sink 19 is used to cool the coolant in the water tank 16, so as to achieve the effect of cooling the coolant that absorbs the superheat, so as to ensure the use effect of liquid cooling heat dissipation.

[0042] The charging pile body 1 has heat dissipation openings on both sides, and heat dissipation fans 22 are fixedly installed on both sides of the charging pile body 1 and at the heat dissipation openings. A dustproof net is installed at the end of the heat dissipation fan 22. The heat dissipation fan 22 is electrically connected to the control components in the charging pile body 1.

[0043] By setting up the cooling fan 22, the heat inside the charging pile body 1 can be discharged easily, so as to assist in the heat dissipation of the charging pile body 1, further improving the heat dissipation effect of the charging pile body 1, and the dust can be filtered through the dustproof net to prevent dust from entering the interior of the charging pile body 1.

[0044] Example 2

[0045] On the basis of the first embodiment, a protection mechanism is added. Figure 5 As shown, a protective mechanism is provided on the top of the charging pile body 1, and the protective mechanism includes dampers 23 fixedly installed in a matrix form at the four corners of the top of the charging pile body 1, a protective plate 24 fixedly connected to the top of the damper 23 and a third spring 25 sleeved on the surface of the damper 23.

[0046] By setting up the protective plate 24, it is convenient to protect the top of the charging pile body 1 to prevent falling objects from causing damage to the charging pile body 1. At the same time, when the falling object contacts and collides with the protective plate 24, the impact force of the falling object can be buffered by the cooperation of the damper 23 and the third spring 25.

[0047] Although the above describes the specific implementation methods of the present invention in conjunction with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or variations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
