Description

Technical Field

[0001] This utility model relates to the field of AC charging pile technology, specifically to an AC charging pile structure that supports multiple outputs. Background Technology

[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. Charging piles are divided into public charging piles and private charging piles. From the perspective of charging method, they are divided into AC charging piles and DC charging piles. AC charging piles are dedicated power supply devices that use conduction to provide AC power to electric vehicles with on-board charging devices.

[0003] For example, patent document CN 215621460 U discloses a multi-output charging pile power module, which relates to a charging pile charging module. Its key technical features include multiple output terminals, a power module, and a multi-selection switch. The multi-selection switch has multiple selectable output terminals and input terminals. The power module converts AC power to DC power, and its output terminals are connected to the input terminals of the multi-selection switch. The multiple output terminals have multiple ports corresponding to the selectable output terminals, and each selectable output terminal is connected to its corresponding port. This invention can achieve the connection between the power module and different ports by controlling the multi-selection switch, changing the output ports of the power module, multiplexing the power module, and improving module utilization.

[0004] However, existing AC charging piles often suffer from high internal heat generation when used for multi-output applications due to structural limitations. This results in insufficient heat dissipation, affecting daily charging power and even causing equipment damage due to overheating. Furthermore, the equipment cannot evenly arrange multiple charging guns and cables, failing to meet daily usage needs. Therefore, there is an urgent need to design an AC charging pile structure that supports multi-output to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide an AC charging pile structure that supports multiple outputs, in order to solve the problems mentioned in the background art. Existing AC charging piles often suffer from high internal heat generation and insufficient heat dissipation due to their own structural limitations when using multiple outputs, which affects the daily charging power and may even cause equipment damage due to overheating. At the same time, the equipment cannot perform the uniform arrangement of multiple charging guns and cables, thus failing to meet the daily use needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an AC charging pile structure supporting multiple outputs, including a charging pile body, an exhaust frame fixedly connected to the top of the charging pile body, an air intake frame fixedly connected to the bottom of the charging pile body, a cable assembly provided at the bottom of the air intake frame, and a charging gun assembly provided on the back of the charging pile body.

[0007] The cable assembly includes a cable base, the bottom end of the air intake frame is fixedly connected to the cable base, and the bottom end of the cable base is fixedly connected to a support base plate.

[0008] The charging gun assembly includes a back frame, which is fixedly connected to the back of the charging pile body.

[0009] Preferably, the side of the back frame is provided with a gun insertion slot, the inside of the gun insertion slot is provided with insertion holes evenly arranged, and the inner wall edge of the gun insertion slot is provided with a sealing strip.

[0010] Preferably, the back of the cable base is provided with a cable groove, and the inner wall edge of the cable groove is provided with an adhesive strip.

[0011] Preferably, the inner wall of the cable tray is provided with compression airbags on the upper and lower sides, and a compression rubber strip is provided between the compression airbags.

[0012] Preferably, ventilation mesh grooves are evenly provided on the sides of the exhaust frame and the air intake frame, ventilation fans are provided at the four corners of the inner wall of the air intake frame, and a ventilation grille is provided in the center of the air intake frame.

[0013] Preferably, a circuit board is provided at the center of the charging pile body, and a ventilation frame is provided at the inner edge of the charging pile body.

[0014] Preferably, the charging pile body is provided with a movable door on the front, and an indicator light is provided on the front of the movable door.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This multi-output AC charging pile structure, through its charging pile body, exhaust rack, air intake rack, ventilation mesh channel, ventilation fan, ventilation grille, circuit board, ventilation frame, movable door, and indicator lights, enables efficient internal heat dissipation for the multi-output AC charging pile. In actual use, the operator first installs the circuit board inside the charging pile body and then completely covers it with the ventilation frame. At this point, simply activating the ventilation fans at the four corners inside the air intake rack allows for rapid circular air intake from the side ventilation mesh channel, which then transports the air in a circular manner into the charging pile body through the ventilation grille, providing ventilation from bottom to top. The ventilation frame provides efficient and continuous heat dissipation for the circuit board, and finally, the air is exhausted through the exhaust rack at the top of the charging pile body, demonstrating the practicality of the equipment design.

[0017] This AC charging pile structure, supporting multiple outputs, further enhances the overall usability of the equipment through its charging pile body, cable tray, support base plate, back frame, gun slot, insertion hole, sealing strip, cable tray, adhesive strip, and clamping airbag. During daily use, operators can route the internal cables of the charging pile through the cable tray on the support base plate. The cable threading point is sealed by the clamping airbags on the upper and lower walls of the cable tray, combined with the clamping strip. The adhesive strip on the edge of the cable tray provides a limiting fit. Simultaneously, the charging gun at one end of the cable can be inserted into the insertion hole of the gun slot on the side of the back frame, with the sealing strip on the upper and lower walls of the gun slot providing a limiting operation. This demonstrates the comprehensiveness of the equipment design. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] A multi-output AC charging pile structure includes a charging pile body 1. An exhaust frame 2 is fixedly connected to the top of the charging pile body 1, and an air intake frame 3 is fixedly connected to the bottom of the charging pile body 1. A cable assembly is provided at the bottom of the air intake frame 3. A charging gun assembly is provided on the back of the charging pile body 1. Ventilation mesh grooves 14 are evenly arranged on the sides of the exhaust frame 2 and the air intake frame 3. Ventilation fans 15 are provided at the four corners of the inner wall of the air intake frame 3. A ventilation grille 16 is provided in the center of the air intake frame 3. A circuit board 17 is provided in the center of the charging pile body 1. A ventilation frame 18 is provided on the inner edge of the charging pile body 1. A movable door 19 is provided on the front of the charging pile body 1. An indicator light 20 is provided on the front of the movable door 19. When the ventilation fans 15 at the four corners of the air intake frame 3 are activated, rapid annular air intake can be achieved from the ventilation mesh grooves 14 on the sides, and then the air is conveyed annularly into the interior of the charging pile body 1 through the ventilation grille 16, thus performing ventilation from bottom to top.

[0027] The cable assembly includes a cable base 4, which is fixedly connected to the bottom of the air intake frame 3. A support base plate 5 is fixedly connected to the bottom of the cable base 4. The charging gun assembly includes a back frame 6, which is fixedly connected to the back of the charging pile body 1. A charging gun slot 7 is provided on the side of the back frame 6. The charging gun slot 7 has evenly arranged insertion holes 8 inside. A sealing strip 9 is provided on the inner edge of the charging gun slot 7. A cable groove 10 is provided on the back of the cable base 4. The inner edge of the cable groove 10 has a cable groove 10. An adhesive strip 11 is provided on the edge of the wall. A compression airbag 12 is provided on the upper and lower inner walls of the cable tray 10. A compression adhesive strip 13 is provided between the compression airbags 12. The internal wires of the charging pile body 1 are routed in the cable tray 10 of the supporting base plate 5. The wires can be sealed and connected by the compression airbags 12 on the upper and lower inner walls of the cable tray 10 and the compression adhesive strip 13 between them. The adhesive strip 11 on the edge of the cable tray 10 is used for limiting and bonding.

[0028] Working principle: During use, the user first installs the circuit board 17 inside the charging pile body 1, and then completely covers it using the ventilation frame 18. At this point, simply activating the ventilation fans 15 at the four corners of the air intake frame 3 allows for rapid, circular air intake from the side ventilation slots 14, followed by circular airflow through the ventilation grille 16 into the charging pile body 1, providing ventilation from bottom to top. The ventilation frame 18 provides efficient and continuous heat dissipation for the circuit board 17, and finally, exhaust air is released through the exhaust frame 2 at the top of the charging pile body 1. However, during daily use, the staff can run the internal wires of the charging pile body 1 through the cable tray 10 of the supporting base plate 5. The cable can be sealed by the upper and lower pressure airbags 12 on the inner wall of the cable tray 10 and the pressure strips 13 between them. The adhesive strips 11 on the edge of the cable tray 10 limit the fit. At the same time, the charging gun at one end of the wire can be inserted into the insertion hole 8 of the gun insertion slot 7 on the side of the back frame 6. The sealing strips 9 on the inner wall of the gun insertion slot 7 limit the fit. The above is the complete working principle of this utility model.
