They mainly include pure electric vehicles, plug-in hybrid vehicles and fuel cell vehicles. Charging piles are used to replenish electricity for pure electric vehicles.

[0003] A patent document with publication number CN215944324U has appeared in the prior art, which discloses an outdoor new energy charging pile that is easy to disassemble and assemble, including a charging pile body, a mounting seat is arranged at the bottom of the charging pile body, a mounting device is arranged inside the mounting seat, and a fixing device is arranged on the side of the mounting seat. The outdoor new energy charging pile that is easy to disassemble and assemble is provided with a motor, a bevel gear rod, a threaded rod and a threaded sleeve. When in use, the output shaft of the motor rotates to drive the first gear to rotate, so that the bevel gear rod rotates, drives the bevel gear to rotate, and the threaded sleeve moves on the threaded rod, so that the clamping plate moves toward the charging pile body to clamp and fix the back of the charging pile.

The device is easy to install and disassemble.

[0004] The above-mentioned and existing technologies have the following defects: during the operation of the charging pile, vehicles will frequently drive around the charging pile, which may easily cause the charging pile to be hit by the vehicles. Since the position of the charging pile is fixed after installation, a rigid collision with greater damage will occur when a collision occurs, causing the charging pile to be easily damaged.

[0005] Therefore, a charging pile for new energy electric vehicles is proposed. Utility Model Content

[0006] The utility model aims to solve the disadvantage that the charging pile is fixed in position after installation, so a rigid collision with greater damage will occur when a collision occurs, and proposes a charging pile for new energy electric vehicles.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a charging pile for new energy electric vehicles, comprising a power supply box and a base, the side wall of the power supply box is electrically connected to a charging gun, the side wall of the power supply box is provided with a plurality of air holes, a buffer structure is arranged between the power supply box and the base, the buffer structure comprises a movable plate, the movable plate is fixedly connected to the power supply box, a fixing ring is fixedly connected to the upper surface of the base, the movable plate is slidably connected to the fixing ring, the arc surface of the fixing ring is fixedly connected to a card frame, the inner wall of the card frame is slidably connected to a slider, one end of the slider is fixedly connected to a transmission rod, the transmission rod passes through the fixing ring, one end of the slider is fixedly connected to a spring, and one end of the spring is fixedly connected to the card frame.

[0008] The effect achieved by the above components is: by setting up a buffer structure, when the new energy electric vehicle collides with the power supply box, the spring will use its own elastic force to slow down the sliding speed of the slider, thereby buffering the slider, and then buffering the power supply box, so that the power supply box can move a certain distance after the collision to reduce the damage caused by the collision, thereby achieving protection for the power supply box.

[0009] Preferably, a damping plate is fixedly connected to the inner wall of the card frame, and the damping plate is slidably connected to the sliding block.

[0010] The effect achieved by the above components is that the friction between the damping plate and the slider can prevent the slider from bouncing back and forth due to the elastic force of the spring, thereby preventing the power supply box from becoming unstable.

[0011] Preferably, a plurality of balls are rotatably connected to the lower surface of the movable plate, and the balls abut against the upper surface of the base.

[0012] The effect achieved by the above components is that the balls can reduce the resistance of the moving plate when it moves.

[0013] Preferably, one end of the transmission rod is fixedly connected to an elastic ball, and the diameter of the elastic ball is larger than the diameter of the transmission rod.

[0014] The effect achieved by the above components is: since the diameter of the elastic ball is larger than the diameter of the transmission rod, when the elastic ball rests against the inner wall of the fixed ring, the elastic ball will use its own elastic force to reduce the collision force between the moving plate and the fixed ring, thereby further buffering the power supply box.

[0015] Preferably, a heat dissipation structure is provided on the surface of the power supply box, and the heat dissipation structure includes an electric push rod, which is fixedly connected to the power supply box, and the output end of the electric push rod is fixedly connected to a top cover, and the lower surface of the top cover is fixedly connected to a hole frame, and the hole frame is slidably connected to the power supply box.

[0017] Preferably, a water retaining ring is fixedly connected to the upper surface of the power supply box, and the size of the water retaining ring is matched with the size of the top cover.

[0018] The effect achieved by the above components is that the water retaining ring can prevent rainwater from flowing into the power supply box from the gap between the top cover and the power supply box, thereby protecting the power supply box.

[0019] Compared with the prior art, the advantages and positive effects of the utility model are:

[0020] 1. In the utility model, by setting a buffer structure, when the new energy electric vehicle collides with the power supply box, the spring will use its own elastic force to slow down the sliding speed of the slider, thereby buffering the slider, and then buffering the power supply box, so that the power supply box can move a certain distance after the collision to reduce the damage caused by the collision, thereby protecting the power supply box.

[0027] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0029] like Figure 1-Figure 4 As shown, the utility model provides a charging pile for a new energy electric vehicle, including a power supply box 1 and a base 3, the side wall of the power supply box 1 is electrically connected to a charging gun 2, the side wall of the power supply box 1 is provided with a plurality of air holes 6, a buffer structure 4 is arranged between the power supply box 1 and the base 3, and a heat dissipation structure 5 is arranged on the surface of the power supply box 1.

[0030] The specific configuration and function of the buffer structure 4 and the heat dissipation structure 5 will be described in detail below.

[0031] like Figure 2 and Figure 3 As shown, the buffer structure 4 includes a moving plate 41, which is fixedly connected to the power supply box 1, a fixing ring 42 is fixedly connected to the upper surface of the base 3, the moving plate 41 is slidably connected to the fixing ring 42, the arc surface of the fixing ring 42 is fixedly connected to a card frame 43, the inner wall of the card frame 43 is slidably connected to a slider 44, one end of the slider 44 is fixedly connected to a transmission rod 45, the transmission rod 45 passes through the fixing ring 42, one end of the slider 44 is fixedly connected to a spring 46, one end of the spring 46 is fixedly connected to the card frame 43, the inner wall of the card frame 43 is fixedly connected to a damping plate 47, the damping plate 47 is slidably connected to the slider 44, and the friction between the damping plate 47 and the slider 44 can prevent The anti-sliding block 44 bounces back and forth due to the elastic force of the spring 46, causing the power supply box 1 to become unstable. The lower surface of the movable plate 41 is rotatably connected to a plurality of balls 48, and the balls 48 abut against the upper surface of the base 3. The balls 48 reduce the resistance of the movable plate 41 when it moves. An elastic ball 49 is fixedly connected to one end of the transmission rod 45. The diameter of the elastic ball 49 is larger than the diameter of the transmission rod 45. Since the diameter of the elastic ball 49 is larger than the diameter of the transmission rod 45, when the elastic ball 49 abuts against the inner wall of the fixed ring 42, the elastic ball 49 will use its own elastic force to reduce the collision force between the movable plate 41 and the fixed ring 42, thereby further buffering the power supply box 1.

[0032] like Figure 4As shown, the heat dissipation structure 5 includes an electric push rod 51, which is fixedly connected to the power supply box 1, and the output end of the electric push rod 51 is fixedly connected to a top cover 52, and the lower surface of the top cover 52 is fixedly connected to a hole frame 53, and the hole frame 53 is slidably connected to the power supply box 1, and the upper surface of the power supply box 1 is fixedly connected to a water retaining ring 54, and the size of the water retaining ring 54 is adapted to the size of the top cover 52. The water retaining ring 54 can prevent rainwater from flowing into the power supply box 1 through the gap between the top cover 52 and the power supply box 1, thereby protecting the power supply box 1.

[0033] The overall working principle is that the charging gun 2 can be inserted into the charging hole of the new energy electric vehicle to charge the new energy electric vehicle. When the new energy electric vehicle collides with the power supply box 1, the power supply box 1 will drive the moving plate 41 to move, and the moving plate 41 will drive the ball 48 to roll along the upper surface of the base 3. At this time, the ball 48 can reduce the resistance of the moving plate 41 when it moves. When the moving plate 41 moves, it will contact the elastic ball 49. After the elastic ball 49 is squeezed, it will drive the transmission rod 45 to slide along the fixed ring 42. The sliding of the transmission rod 45 will drive the slider 44 to slide along the inner wall of the card frame 43. At this time, the spring 46 will be compressed by the slider 44, and the spring 46 will use its own elastic force to delay the sliding speed of the slider 44, thereby buffering the slider 44, and then the power supply box. 1 is used for buffering, so that the power supply box 1 can move a certain distance after being hit to reduce the damage caused by the collision, thereby protecting the power supply box 1. At the same time, the slider 44 will slide along the surface of the damping plate 47. The friction between the damping plate 47 and the slider 44 can prevent the slider 44 from bouncing back and forth due to the elastic force of the spring 46, which may cause the power supply box 1 to be unstable. Since the diameter of the elastic ball 49 is larger than the diameter of the transmission rod 45, when the elastic ball 49 is against the inner wall of the fixed ring 42, the elastic ball 49 will use its own elastic force to reduce the collision force between the moving plate 41 and the fixed ring 42, thereby further buffering the power supply box 1. When the collision from the outside disappears, the spring 46 begins to stretch to reset the moving plate 41, and the reset of the moving plate 41 will drive the power supply box 1 to reset.

[0034] When it is necessary to improve the heat dissipation effect of the power supply box 1, the electric push rod 51 is turned on, and the extension of the output end of the electric push rod 51 will drive the top cover 52 to move upward, and the movement of the top cover 52 will drive the hole frame 53 to slide out from the inner wall of the power supply box 1, so that the hot air gathered at the upper end of the power supply box 1 is discharged, thereby improving the heat dissipation effect of the power supply box 1 and improving the practicality of the power supply box 1. When it rains, the output end of the electric push rod 51 is controlled to contract, and the top cover 52 will drive the hole frame 53 to slide into the power supply box 1, and then the top cover 52 will be covered on the outer periphery of the water retaining ring 54. The water retaining ring 54 can prevent rainwater from flowing into the power supply box 1 from the gap between the top cover 52 and the power supply box 1, thereby protecting the power supply box 1.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
