Description

Technical Field

[0001] This utility model relates to the technical field of dual-gun DC chargers, specifically a bellows-type dual-gun DC charger. Background Technology

[0002] The bellows-type dual-gun DC charger is a DC charging device integrating dual charging interfaces and employing an air-cooled heat dissipation design. Its efficient cooling system ensures stable operation, supports simultaneous fast charging for two electric vehicles, features intelligent management to optimize charging efficiency, and utilizes a modular structure for improved maintenance convenience. It is suitable for public charging stations, commercial parking lots, and other similar scenarios. Traditional bellows-type dual-gun DC chargers provide DC fast charging for electric vehicles by converting AC to DC and outputting it to the battery at a higher power, significantly shortening charging time, meeting users' needs for rapid energy replenishment, reducing waiting time, and improving user experience. However, in actual use, the airflow paths for hot and cold air are not clearly defined. Cold air cannot accurately enter the areas requiring heat dissipation, and hot air is also difficult to expel efficiently, resulting in low heat dissipation efficiency. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a bellows-type dual-gun DC charger, which has the advantages of a structured heat dissipation path design, improving heat dissipation efficiency, and solving the problems of unclear hot and cold air flow paths, difficulty in accurately entering the component area that needs heat dissipation, and difficulty in efficiently expelling hot air, resulting in low heat dissipation efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bellows-type dual-gun DC charger, comprising a pile body, an air duct baffle fixedly connected to the inner wall of the pile body, a cold air intake mechanism fixedly connected to the bottom of the inner wall of the pile body, a negative pressure exhaust mechanism fixedly connected to the front side of the inner wall of the air duct baffle, and an exhaust port opened at the bottom of the left side of the pile body; wherein, the cold air intake mechanism includes a wind-cooling module, the wind-cooling module is fixedly connected to the bottom of the inner wall of the pile body, an air inlet louvered protective window is fixedly connected to the rear side of the wind-cooling module, a cold air inlet is opened at the bottom of the rear side of the pile body, and cold air chambers are opened on both sides of the wind-cooling module.

[0005] In the above technical solution, the bellows-type dual-gun DC charger provided by this utility model has the following beneficial effects:

[0006] This utility model divides the interior of the charging pile into hot and cold air zones using a duct partition. Combined with the cold air intake mechanism at the bottom, the air-cooling module, air inlet louvered protective window, cold air inlet, and cold air cavity draw in external cold air for precise heat dissipation of the electronic components at the bottom of the charging pile. At the same time, the negative pressure exhaust mechanism at the front of the duct partition forms an airflow path, allowing hot air to be discharged from the top. This solves the problems of unclear hot and cold air flow paths and low heat dissipation efficiency in traditional chargers, and achieves a structured design of the heat dissipation path, thereby improving heat dissipation efficiency.

[0013] Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of the present invention.

[0014] like Figures 1 to 6 As shown, the present invention includes a pile body 1, an air duct baffle 5 fixedly connected to the inner wall of the pile body 1, a cold air intake mechanism 6 fixedly connected to the bottom of the inner wall of the pile body 1, a negative pressure exhaust mechanism 7 fixedly connected to the front side of the inner wall of the air duct baffle 5, and an exhaust port 13 opened at the bottom of the left side of the pile body 1.

[0015] The cold air intake mechanism 6 includes a cold air module 61, which is fixedly connected to the bottom of the inner wall of the pile body 1. A protective window 62 with an air inlet louver is fixedly connected to the rear side of the cold air module 61. A cold air inlet 63 is opened at the bottom of the rear side of the pile body 1. Cold air chambers 64 are opened on both sides of the cold air module 61.

[0016] refer to Figure 5The negative pressure exhaust mechanism 7 includes a wind box cover plate 71, which is fixedly connected to the top and bottom of the front side of the inner wall of the air duct partition 5. A fan mounting plate 72 is fixedly connected to the rear side of the wind box cover plate 71, and a centrifugal fan 73 is fixedly connected to the rear side of the fan mounting plate 72.

[0017] As a technical optimization of this utility model, by setting up a wind box cover plate 71, a fan mounting plate 72 and a centrifugal fan 73, the centrifugal fan 73 rotates at high speed to generate negative pressure, forcibly extracting hot air from the pile body 1 and accelerating air flow. This design enhances heat dissipation power through active exhaust and avoids hot air stagnation. Combined with the cold air intake mechanism 6, it forms a "bottom in, top out" convection cycle, ensuring efficient and continuous heat dissipation and solving the problem of insufficient passive heat dissipation efficiency of traditional devices.

[0018] refer to Figure 5 The main frame of the air box is fixedly connected to the rear side of the air box cover plate 71. The inner wall of the main frame of the air box is fixedly connected to the air duct guide plate 9. A hot air inlet 10 is opened on the rear side of the main frame of the air box, and a hot air outlet 11 is opened on the left side of the main frame of the air box.

[0019] As a technical optimization of this utility model, by setting up a main frame 8 of the air box, a duct guide plate 9, a hot air inlet 10 and a hot air outlet 11, the duct guide plate 9 guides the flow of hot air within the main frame 8 of the air box, so that after the hot air enters from the hot air inlet 10, it is discharged through the hot air outlet 11 along a preset path, avoiding airflow turbulence. This structure optimizes the discharge path of hot air, reduces energy loss, ensures the orderly discharge of hot air, and further improves the efficiency and stability of the heat dissipation system.

[0020] refer to Figure 5 A front door 2 is movably connected to the front side of pile 1, a right door 3 is movably connected to the right side of pile 1, and a left door 4 is movably connected to the left side of pile 1.

[0021] As a technical optimization of this utility model, by setting an exhaust port 13, hot air from the top of the pile body 1 can smoothly enter the negative pressure exhaust mechanism 7. The exhaust port 13 then discharges the hot air discharged from the main frame 8 of the air box to the outside. The two work together to form an "air intake at the top and exhaust at the side" outlet channel, ensuring that the hot air is completely discharged from the pile body 1, avoiding accumulation inside, and ensuring the integrity of the heat dissipation cycle.

[0022] refer to Figure 3 A hot air inlet 14 is provided at the bottom right side of the left door 4, and the inner wall of the exhaust vent 13 is connected to the inner wall of the hot air inlet 14.

[0023] As a technical optimization of this utility model, by setting a hot air interface 14, which is directly connected to the hot air outlet 11 and the exhaust port 13 of the main frame 8 of the ventilation box, the transmission distance of hot air in the pile body 1 is shortened and the heat retention time is reduced. This design optimizes the path so that hot air can be discharged quickly, further improving the heat dissipation efficiency and ensuring that the internal temperature of the charger is controllable when it is running at high power.

[0024] refer to Figure 1 Charging guns 15 are symmetrically inserted into both sides of the left door 4 and the right door 3. An emergency stop button 16 is installed on the top of the charging gun 15 on the right side of the right door 3.

[0025] As a technical optimization of this utility model, by setting a charging gun 15 and an emergency stop button 16, it can support charging two electric vehicles at the same time, improve charging efficiency, reduce user waiting time, and is suitable for high-flow charging scenarios. It is installed on the top of the charging gun 15 so that users can quickly trigger it in emergency situations such as leakage or fire, immediately cut off the power supply, and ensure personal and equipment safety during the charging process.

[0026] refer to Figure 1 The top two sides of the pile body 1 are fixedly connected to the swing arm balancer 17.

[0027] As a technical optimization of this utility model, by setting a swing arm balancer 17, the swing arm balancer 17 is used to support the swing arm of the charging gun 15, reducing the operating resistance when the user plugs and unplugs the charging gun 15, making the swing arm move more smoothly. This design improves the convenience of charging operation, reduces the user's labor intensity, and avoids interface wear caused by swing arm swaying, thus extending the service life of the equipment.

[0028] refer to Figure 1 A touch screen 18 is fixedly connected to the top of the front side of the front door 2, and a card reader 19 is fixedly connected to the right side of the touch screen 18.

[0029] As a technical optimization of this utility model, by setting a touch screen 18 and a card reader 19, a human-machine interface is provided, allowing users to view charging status such as power, current, and voltage, and set charging parameters such as charging amount and power, thereby realizing intelligent operation, improving user experience, supporting the reading of charging card information, realizing automatic settlement of charging fees and user identity verification, simplifying the charging process, and improving the convenience and intelligence level of equipment management.

[0030] The working principle and usage process of this utility model are as follows: When in use, the air-cooling module 61 in the cold air intake mechanism 6 is fixed to the bottom of the inner wall of the pile body 1. External air enters through the cold air inlet 63 at the bottom of the rear side of the pile body 1. After being filtered by the air-cooling module 61 through the air inlet louver protective window 62, it is delivered to the bottom of the pile body 1 through both sides of the air-cooling module 61 in the cold air cavity 64. The cold air cavity 64 guides the cold air to the electronic components inside the pile body 1, absorbs the heat generated by the operation of the components, and forms hot air. The hot air moves upward due to the increase in temperature and the decrease in density.

[0031] At this time, the centrifugal fan 73 in the negative pressure exhaust mechanism 7 is fixed to the rear side of the fan mounting plate 72. The fan mounting plate 72 is fixed to the rear side of the air box cover plate 71. The air box cover plate 71 is fixed to the top and bottom of the front side of the inner wall of the air duct partition 5. The centrifugal fan 73 rotates at high speed to generate negative pressure. The hot air in the upper part of the pile body 1 is drawn through the top of the front side of the air duct partition 5. The hot air enters through the hot air inlet 10 behind the air box cover plate 71 of the air box main frame 8. Under the guidance of the air duct guide plate 9 and the inner wall of the air box main frame 8, it flows along the preset path to the left side of the air box main frame 8, the hot air outlet 11. The hot air discharged from the hot air outlet 11 is introduced into the exhaust port 13 at the bottom left side of the left door 4 through the hot air interface 14 at the bottom right side of the left door 4, and finally discharged to the outside of the pile body 1.

[0032] The design of connecting the hot air inlet 14 and the exhaust vent 13 shortens the hot air transmission path and reduces heat retention. The charging guns 15 on both sides of the left door 4 and the right door 3 can be inserted into the charging ports of two electric vehicles at the same time. The internal circuit of the charger converts AC power into DC power and outputs it to the vehicle battery through the dual guns at high power to achieve fast charging. The emergency stop button 16 on the top right side of the right door 3 is located on the top of the charging gun 15 and is directly connected to the charging circuit.

[0033] In case of emergency such as leakage or overload, the user can press the emergency stop button 16 to immediately cut off the power and terminate charging. The touch screen 18 on the top of the front door 2 provides a human-machine interface, where the user can view the charging status, power, current, voltage, and set charging parameters such as charging amount and power mode. The card reader 19 on the right side of the touch screen 18 supports reading charging card information and automatically completes payment settlement and user authentication. The swing arm balancers 17 on both sides of the top of the charging pile 1 support the swing arm of the charging gun 15. By balancing the counterweight, the resistance when the user plugs and unplugs the charging gun 15 is reduced, making the swing arm move smoothly, reducing the intensity of operation, and avoiding wear and tear on the interface due to shaking.

[0034] The duct baffle 5 divides the interior of the pile body 1 into hot and cold air zones. Together with the cold air intake mechanism 6 and the negative pressure exhaust mechanism 7, they form a "bottom-in, top-out" heat dissipation cycle. Cold air is drawn in from the bottom for heat dissipation, while hot air flows upwards under negative pressure, exiting through the main frame 8, the hot air interface 14, and the exhaust port 13. The entire charger, through this "cold air intake → heat exchange → negative pressure exhaust" heat dissipation cycle, along with the dual-gun charging function and safety control module, solves the problems of low heat dissipation efficiency and cumbersome charging processes inherent in traditional chargers. The structured design of the duct baffle 5, the cold air intake mechanism 6, and the negative pressure exhaust mechanism 7 creates a clear airflow path, ensuring efficient heat dissipation.

[0035] The dual-gun charging and intelligent interaction module enhance the device's usability and user experience, achieving a balance between efficient charging and safe operation.

[0036] In summary: This bellows-type dual-gun DC charger, by setting up a wind duct baffle 5, divides the interior of the pile body 1 into hot and cold air zones. In conjunction with the bottom cold air intake mechanism 6, the air-cooling module 61, the air inlet louver protective window 62, the cold air inlet 63, and the cold air cavity 64, it draws in external cold air to precisely dissipate heat from the electronic components at the bottom of the pile body 1.

[0037] At the same time, the negative pressure exhaust mechanism 7 on the front side of the air duct partition 5 forms an air flow path, allowing hot air to be discharged from the top, which solves the problems of unclear hot and cold air flow paths and low heat dissipation efficiency in traditional chargers.
