[0002] A new energy vehicle charging pile is a device that provides power replenishment for new energy vehicles. The new energy vehicle charging pile includes a charging module, a control module, a metering module, a relay, a charging gun, etc.

[0003] The new energy vehicle charging pile is fixed on the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential community parking lots or charging stations, and can charge various models of electric vehicles according to different voltage levels. Since most new energy vehicle charging piles are installed at the rear side of the parking space, after the driver makes an operation error, he will hit the installed new energy vehicle charging pile, resulting in damage to the new energy vehicle charging pile. Since the maintenance period of the new energy vehicle charging pile is long, and at the same time, the power supply equipment installed inside the new energy vehicle charging pile will short-circuit after being squeezed and deformed, thus causing a fire, which will result in a large amount of public property losses.

[0021] Further, the upper pile body includes a cabinet body and a top cover;

[0022] The top cover is installed above the cabinet body. A rectangular slot is opened at the top end of the cabinet body. The cabinet body is communicated with the top cover through the rectangular slot. The bottom end of the cabinet body is a concave surface. Grooves are opened on the opposite two side surfaces of the cabinet body. The concave surface is fitted on the upper surface of the outer shell body. At the same time, the top end of the connecting rod is located in the groove, and the connecting rod is fixedly installed in the groove by a rivet;

[0023] The upper surface of the outer shell body is an arc surface, and the outer diameter of the arc surface is the same as the inner diameter of the concave surface.

[0024] Further, a channel is provided inside the top cover, and an exhaust fan is installed in the channel.

[0025] A new energy vehicle charging pile group further includes an inner support;

[0026] The inner support is installed inside the cabinet body. Side plates are provided on the opposite two outer side surfaces of the inner support. One side edge of the side plate is attached to the corresponding inner wall of the cabinet body. A through groove is opened on the inner wall of the cabinet body, and the bottom edge of the through groove is aligned with one side edge of the side plate;

[0031] The present invention has the following beneficial effects:

[0032] 1. In the present invention, the shaft body sleeved with two side supports is installed inside the base. After installation, the side supports can only rotate around the shaft body. When the upper pile body is stressed, the upper pile body drives the side supports to rotate around the shaft body, and at the same time, the elastic support member is compressed. Through the offset of the upper pile body, the impact force received by the upper pile body is released, reducing the stress on the upper pile body itself, thereby reducing the damage or deformation of the upper pile body.

[0033] 2. When the exhaust fan of the present invention is working, the air inside the cabinet is discharged through the channel. At the same time, the channel is located at the top of the cabinet, and the hot air inside the cabinet will converge towards the top. The exhaust fan facilitates the discharge of the hot air, and fresh air enters the inside of the cabinet through the bottom of the cabinet, thereby achieving cooling and heat dissipation.

[0034] 3. Bar-shaped limiting grooves are provided on the opposite inner side surfaces of the cabinet body of the present invention. The end of the moving rod moves along the bar-shaped limiting groove. Under the action of gravity, the moving rod and the rotating wheel slide along the bar-shaped limiting groove to the lowest position. Through the downward interaction of the moving rod and the rotating wheel under the action of gravity, the charging cable is driven to bend and be stored inside the outer casing, avoiding the charging cable being exposed outside for a long time and completing the protection of the charging cable.

[0035] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] Please refer to Figures 1 - 6 and Figure 12 As shown, the present invention is a new energy vehicle charging pile, including:

[0053] The upper pile body, the upper pile body includes a cabinet body 6 and a top cover 8;

[0054] A top cover 8 is installed above the cabinet body 6. A rectangular slot hole 605 is opened at the top end of the cabinet body 6. The cabinet body 6 communicates with the top cover 8 through the rectangular slot hole 605. The bottom end of the cabinet body 6 is a concave surface 601. Grooves 602 are opened on the opposite side surfaces of the cabinet body 6. The concave surface 601 is fitted on the upper surface of the outer shell 1. At the same time, the top end of the connecting rod 403 is located in the groove 602, and the connecting rod 403 is fixedly installed in the groove 602 by rivets;

[0055] The upper surface of the outer shell 1 is an arc surface. The outer diameter of the arc surface is the same as the inner diameter of the concave surface 601. The cabinet body 6 rotates along the upper surface of the outer shell 1;

[0056] Inside the top cover 8, there is a channel 801. An exhaust fan 9 is installed in the channel 801, and a rain shield 802 is installed at the outer port of the channel 801, effectively reducing the entry of external rainwater into the interior of the channel 801 through the outer port of the channel 801, protecting the exhaust fan 9 installed in the channel 801, and at the same time preventing rainwater from entering the cabinet body 6 through the channel 801 and causing damage to the power equipment;

[0057] When the exhaust fan 9 is working, the air inside the cabinet body 6 is discharged through the channel 801. At the same time, the channel 801 is located at the top of the cabinet body 6, and the hot air inside the cabinet body 6 will converge towards the top. It is convenient to discharge the hot air through the exhaust fan 9, and fresh air enters the interior of the cabinet body 6 through the bottom of the cabinet body 6, thereby achieving cooling and heat dissipation.

[0058] The lower pile body is located below the upper pile body. The lower pile body and the upper pile body are connected by a connecting piece 4, and the bottom end of the upper pile body fits on the upper end of the lower pile body;

[0059] The lower pile body includes an outer shell 1 and a base 2. A base 5 is installed on the bottom surface of the base 2. The outer shell 1 is of a U-shaped structure, and circular holes 201 are opened on both opposite side plates of the outer shell 1;

[0060] The outer shell 1 is sleeved outside the base 2, and a cavity is formed between the outer shell 1 and the base 2. Two arc-shaped slot holes 101 are opened on the outer shell 1, and the arc-shaped slot holes 101 are correspondingly distributed with the side brackets 401. The top ends of the side brackets 401 pass through the arc-shaped slot holes 101 and extend outwards, and the top ends of the side brackets 401 can swing within the arc-shaped slot holes 101;

[0061] The connecting piece 4 includes side brackets 401, a shaft body 402, and an elastic support member. Two side brackets 401 are installed on the shaft body 402, and both side brackets 401 are connected to the elastic support member. The installed elastic support member pushes the side brackets 401 to maintain a vertical state. The side brackets 401, the shaft body 402, and the elastic support member are all installed inside the lower pile body, and the top ends of the side brackets 401 extend out of the lower pile body and are connected to the upper pile body;

[0062] The end of the shaft body 402 is installed in the corresponding circular hole 201. After installation, the shaft body 402 can rotate around its own axis, and at the same time, the shaft body 402 and the circular hole 201 are installed with a limit through a limit ring;

[0063] During installation, first install the shaft body 402 sleeved with two side brackets 401 inside the base 2. After installation, the side brackets 401 can only rotate around the shaft body 402;

[0064] When the upper pile body is stressed, the upper pile body drives the side support 401 to rotate around the shaft body 402, and at the same time compresses the elastic support member. Through the offset of the upper pile body, the impact force received by the upper pile body is released, reducing the stress on the upper pile body itself.

[0065] The elastic support member includes a rod-shaped member 404. Both ends of the rod-shaped member 404 are installed in the installation holes provided in the inner wall of the outer shell 1. Both ends of the rod-shaped member 404 extend out of the outer shell 1. The extended ends of the rod-shaped member 404 are prism structures. By cooperating with the prism end with a tool, the rod-shaped member 404 is driven to rotate. Two movable blocks 405 are cooperatively installed on the rod-shaped member 404. A cross bar 406 is installed on the movable block 405. The cross bar 406 is connected to the connecting rod 403 through a plurality of push rods 407. A plurality of springs 408 are provided between the connecting rod 403 and the cross bar 406. The springs 408 are sleeved on the push rods 407. Extension arms are provided on both opposite sides of the side support 401. The connecting rod 403 is installed between the extension arms on the same side of the two side supports 401. The rod-shaped member 404 is installed between the opposite inner walls of the outer shell 1;

[0066] Two connecting rods 403 are installed between the two side supports 401. The ends of the connecting rods 403 are installed on the extension arms of the side supports 401. During the process of the side support 401 rotating around the shaft body 402 to one side, the connecting rod 403 compresses a plurality of springs 408 installed on this side. Since the side support 401 is connected to the outer shell 1, when the outer shell 1 is impacted, the outer shell 1 drives the side support 401 and the connecting rod 403 to rotate in the opposite direction of the impact object and compresses a plurality of springs 408 located in the opposite direction, thereby achieving the purpose of unloading force;

[0067] The bottom end of the push rod 407 is provided with a deep groove. The push rod 407 is clamped on the outside of the cross bar 406 through the deep groove. A slot hole is provided at the other end of the push rod 407. The connecting rod 403 passes through the slot hole. A plurality of push rods 407 are installed on the connecting rod 403. At the same time, the push rod 407 and the connecting rod 403 can rotate relative to each other. The two groups of push rods 407 installed are distributed in a figure-eight shape;

[0068] The rod-shaped member 404 includes a first rod body 4041 and a second rod body 4042. The outer side surface of the second rod body 4042 is a stepped surface. One end of the second rod body 4042 is sleeved with the first rod body 4041. The first rod body 4041 and the second rod body 4042 are connected by a limiting ring 4043. The first rod body 4041 and the second rod body 4042 can rotate relative to each other. Nuts are cooperatively installed at the ends of the first rod body 4041 and the second rod body 4042 extending out of the outer shell 1 for limiting;

[0069] Both the first rod body 4041 and the second rod body 4042 are provided with external threads, and movable blocks 405 are threadedly connected to the outsides of the first rod body 4041 and the second rod body 4042. At the same time, the cross bar 406 installed on the movable block 405 is perpendicular to the rod-shaped member 404.

[0070] One end of the second rod body 4042 extends out of the base 2, and the extending end of the second rod body 4042 is connected to the rectangular plate 409.

[0071] The rectangular plate 409 is located outside the lower pile body. At the same time, on the side of the rectangular plate 409 close to the parking space, the tail of the vehicle is relatively low. During the reverse parking process, after hitting the charging pile, it first hits the rectangular plate 409, and the second rod body 4042 is pushed to move backward through the rectangular plate 409;

[0072] Since the first rod body 4041 and the second rod body 4042 are limited by the limiting ring 4043, the limiting ring 4043 is damaged after the impact, realizing the second rod body 4042 to slide backward along the first rod body 4041;

[0073] At the same time, a movable block 405 is fitted and installed on the external thread of the second rod body 4042. The movable block 405 moves synchronously with the second rod body 4042, and the movable block 405 drives the connecting rod 403 connected thereto to move backward. The pressure on the spring 408 in contact with the connecting rod 403 is reduced, and the spring 408 on the other side pushes the two side brackets 401 and the two connecting rods 403 installed to rotate backward, realizing the upper pile body connected to the side bracket 401 to fall backward, avoiding the upper pile body from being hit by the vehicle again;

[0074] When the tail of the vehicle is relatively high, during the reverse parking process, after hitting the upper pile body, the upper pile body drives the side bracket 401 to rotate around the shaft body 402 and compresses the spring 408 on one side, thereby realizing force unloading and reducing the damage degree of the upper pile body after being hit.

[0075] An air outlet hole 102 is opened at the upper end of the outer housing 1. A fan group 3 is fitted and installed in the air outlet hole 102. The air outlet hole 102 is communicated with the inside of the upper pile body. Air inlet holes 103 are opened on the opposite two side surfaces of the outer housing 1, and plate filters 104 are installed in the air inlet holes 103;

[0076] By allowing air to enter from the lower end, external cold air enters through the lower end and is discharged through the upper end, thereby improving the discharge effect of hot air and the heat dissipation effect. Through the installed plate filter 104, external dust can be effectively blocked from entering the upper pile body.

[0077] Embodiment 2;

[0078] Such as Figures 7 - 11 , a new energy vehicle charging pile group, the difference feature from Embodiment 1 is: it further includes an inner bracket 7;

[0079] An inner support 7 is installed inside the cabinet body 6. Side plates 701 are provided on the opposite outer sides of the inner support 7. One side edge of the side plate 701 is attached to the corresponding inner wall of the cabinet body 6. A through groove 603 is formed on the inner wall of the cabinet body 6, and the bottom edge of the through groove 603 is aligned with one side edge of the side plate 701.

[0080] A plurality of waist-shaped holes 604 are formed at the bottom of the inner support 7, and the waist-shaped holes 604 communicate with the inside of the outer casing 1.

[0081] A power supply assembly 10 is installed inside the inner support 7, and a charging cable 13 extending from the power supply assembly 10 passes through the waist-shaped hole 604 on the cabinet body 6 and extends out of the cabinet body 6.

[0082] The water droplets or sundries entering through the waist-shaped hole 604 are discharged through the through groove 603. At the same time, the external air flows through the through groove 603 and the waist-shaped hole 604, realizing heat exchange with the outer wall of the inner support 7.

[0083] The side of the inner support 7 is flush with the side edge of the opening formed on one side of the outer casing 1, and a cabinet door is fitted and installed outside the opening of the outer casing 1.

[0084] The inside of the outer casing 1 is divided into two cavities by the inner support 7. The two cavities are the inner cavity of the inner support 7 and the outer cavity of the inner support 7. The inner cavity of the inner support 7 communicates with the inside of the top cover 8.

[0085] At the same time, the outer cavity of the inner support 7 is divided into an upper cavity outside the inner support 7 and a lower cavity outside the inner support 7 by two side plates 701. The lower cavity outside the inner support 7 enables the inside of the lower pile body to communicate with the inner cavity of the inner support 7.

[0086] A moving rod 11 is installed inside the cabinet body 6, a runner 12 is sleeved on the moving rod 11, and the charging cable 13 passes through the runner 12.

[0087] Bar-shaped limiting grooves 606 are provided on the opposite inner sides of the cabinet body 6. The end of the moving rod 11 moves along the bar-shaped limiting groove 606. Under the action of gravity, the moving rod 11 and the runner 12 slide along the bar-shaped limiting groove 606 to the lowest position.

[0088] Under the action of gravity, the moving rod 11 and the runner 12 move downward, driving the charging cable 13 to bend and be stored inside the outer casing 1, avoiding the charging cable 13 being exposed outside for a long time and completing the protection of the charging cable 13.
