Abstract
Description
Technical Field
[0001] This utility model relates to the field of charging piles, and in particular to a dustproof and heat-dissipating charging pile. Background Technology
[0002] Charging stations, as key equipment for providing power to electric vehicles such as electric cars, are like gas stations for traditional gasoline vehicles. They are an important infrastructure for promoting electric vehicles, and the use of dustproof and heat-dissipating charging stations is extremely necessary. Once dust enters the charging station, it will adhere to the precision electronic components and circuits, affecting heat dissipation and insulation performance, accelerating component aging, and causing faults and safety hazards such as short circuits and leakage. It will also damage the appearance. Dustproof design can effectively avoid these problems. During charging, the power modules, transformers and other components inside the charging station will generate a lot of heat. If heat is not dissipated in time, the components are easily damaged due to excessive temperature, reducing charging efficiency and even causing safety accidents. A good heat dissipation system can prevent overheating damage and ensure the safe and efficient operation of the equipment.
[0003] Existing dustproof and heat-dissipating charging piles achieve their functions in various ways. For dust prevention, physical barriers are used, such as sealing the connection parts and interfaces with sealing materials and structures, and installing dust screens on ventilation and heat dissipation vents to remove dust. Some also use positive pressure dust prevention systems, which prevent dust from entering by making the internal air pressure higher than the external air pressure. For heat dissipation, natural convection is relied upon. By utilizing the natural convection characteristics of air, hot air is exhausted and cold air enters through the heat dissipation channels, heat dissipation holes and internal heat dissipation fins on the outer shell to remove heat. Forced air cooling uses fans installed at the air inlet or outlet, in conjunction with the air duct design, to force air to flow quickly over the heat-generating components to dissipate heat. For high-power charging piles, water cooling is more commonly used. A circulation system consisting of a water tank, water pump, radiator and cooling pipes is used. The coolant circulates to absorb the heat from the heat-generating components and then dissipates it to the outside through the radiator. After cooling, it circulates again to achieve efficient heat dissipation.
[0004] In the current practical use of dustproof and heat-dissipating charging piles, a rather thorny problem remains unresolved. Traditional heat dissipation methods, such as natural convection heat dissipation which relies on heat dissipation channels and vents on the outer shell, and forced air cooling which uses fans to promote airflow, while having a certain effect in heat dissipation, have exposed major defects in dust prevention. During equipment operation, internal heat is continuously dissipated, driving air to form airflow. This airflow easily carries dust from the surrounding environment, which sneaks in through the splicing gaps of the charging pile's outer shell, the tiny gaps at the edges of the vents, and various interface gaps. Once a large amount of dust enters the equipment, it will adhere to the surfaces of key electrical components, complex circuit boards, and important heat dissipation devices, seriously interfering with the normal operation of the equipment and greatly diminishing the high efficiency that dustproof and heat-dissipating charging piles should possess. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a dustproof and heat-dissipating charging pile, which aims to improve the problem that traditional heat dissipation methods easily allow dust to enter the equipment through gaps during use.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dustproof and heat-dissipating charging pile, including a shell, an operation screen electrically connected to the top of the shell, charging components on both sides of the shell, a power transmission device fixedly connected inside the shell, a cooling water tank on one side of the shell, a water pump fixedly connected inside the cooling water tank, the input end of the water pump being connected to the inside of the cooling water tank, and a heat dissipation component on one side of the cooling water tank;

[0014] As a further description of the above technical solution:
[0015] Each of the connecting columns has multiple sliding columns fixedly connected to its outer wall, and a connecting rod fixedly connected to one end of each connecting column.

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the water pump is first started to drive the cooling water inside the cooling water tank to start moving. The cooling water first passes through the water pump from inside the cooling water tank into the input pipe, and then flows into the heat dissipation pipe to carry away the heat generated by the power transmission device during power transmission. After that, it flows into the return pipe and returns to the cooling water tank to continue the next cycle. This achieves the effect of removing the heat generated by the power transmission device during equipment use by using water cooling. It avoids the problem that dust can easily enter the equipment through gaps during equipment use, which is common with traditional heat dissipation methods. This improves the efficiency of the dustproof and heat dissipation charging pile.
[0024] 2. In this utility model, first grasp the connecting rod and pull it outward, so that the fixing pin disengages from the inside of the connecting hole. At the same time, the limiting strip slides inside the sliding groove, thereby unlocking the rain shelter. Then, rotate the rain shelter to the required angle, and then release the connecting rod so that it moves inward under the action of the spring, so that the fixing pin slides into the corresponding connecting hole. This achieves the effect of changing the angle of the rain shelter according to actual needs during equipment use, avoiding the problem of needing to install rain shelters of different angles for different locations during equipment use, thereby improving the practicality of the dustproof and heat dissipation charging pile.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0033] Reference Figures 1-3 The present invention provides an embodiment of a dustproof and heat-dissipating charging pile, comprising a housing 1, an operation screen 2 electrically connected to the top of the housing 1 for operating internal data, charging components on both sides of the housing 1 for charging vehicles, a power transmission device 5 fixedly connected inside the housing 1 for transmitting electrical energy to the charging components, a cooling water tank 6 on one side of the housing 1 for containing cooling water, a water pump 7 fixedly connected inside the cooling water tank 6 for providing power for the flow of cooling water, the input end of the water pump 7 being connected to the inside of the cooling water tank 6, and a heat dissipation component on one side of the cooling water tank 6 for dissipating heat from the inside of the power transmission device 5.
[0034] The heat dissipation assembly includes an input pipe 8, a heat dissipation pipe 9, and a return pipe 10. One end of the input pipe 8 is fixedly connected to the output end of the water pump 7 and is used to guide cooling water into the heat dissipation pipe 9. One end of the heat dissipation pipe 9 is fixedly connected to one end of the input pipe 8 and is used to carry away the heat generated by the power transmission device 5. One end of the return pipe 10 is fixedly connected to one end of the heat dissipation pipe 9 and allows the cooling water that has absorbed heat to flow back into the cooling water tank 6. One end of the return pipe 10 is fixedly connected to the inside of the cooling water tank 6. Each charging assembly includes a power transmission line 3 and a connecting gun 4. One end of each power transmission line 3 is electrically connected to one side of the outer casing 1 for transmitting power. The bottom of each connecting gun 4 is fixedly connected to one end of the power transmission line 3 and is connected to the vehicle to charge the vehicle.
[0035] Specifically, when the equipment is turned on to charge the car, the water pump 7 is the first to respond and start, using stable and strong power to drive the coolant inside the coolant tank 6 to flow. This coolant first enters the inlet pipe 8 from inside the coolant tank 6 via the water pump 7, and then flows into the radiator pipe 9. The radiator pipe 9 is tightly wrapped around the power transmission device 5. At this time, the power transmission device 5 is performing the power transmission task, continuously delivering electrical energy to the car. However, in this process, the power transmission device 5 generates a lot of heat. The coolant, with its lower temperature, exchanges heat with the heat generated by the power transmission device 5, carrying away this heat. The coolant that has completed heat absorption then flows gently along the return pipe 10, returning to the coolant tank 6, ready to start the next heat transfer cycle, continuously ensuring the stable operation of the equipment.
[0036] Reference Figure 4 and Figure 5 The top of the outer casing 1 is fixedly connected to multiple support rods 11 for supporting the rain shelter 20. Each support rod 11 has a turntable 12 fixedly connected to its top for adjusting and fixing the angle of the rain shelter 20. Each turntable 12 has multiple connecting holes 13 on one side for accommodating fixing pins 18. Each turntable 12 has a connecting post 14 slidably connected inside for connecting to a connecting rod 17. Each connecting post 14 has multiple sliding posts 15 fixedly connected to its outer wall to limit its movement. Each connecting post 14 has a connecting rod 17 fixedly connected to one end, and the connecting fixing pin 18 controls the angle of the rain shelter 20. Each sliding column 15 is provided with a spring 16 on one side to provide elastic force to the connecting rod 17. One end of each spring 16 is fixedly connected to the inside of the sliding column 15, and the other end of each spring 16 is fixedly connected to the inside of the turntable 12. Each connecting rod 17 is fixedly connected with a fixing pin 18 on one side to fix the angle of the rain shelter 20. Each connecting rod 17 is fixedly connected with a limit strip 19 at the top to limit the range of movement of the connecting rod 17. The top of the turntable 12 is rotatably connected to the rain shelter 20, which can block rainwater from falling onto the equipment when it rains outside. The bottom of the rain shelter 20 is provided with multiple sliding grooves 21 to accommodate the limit strips 19.
[0037] Specifically, when adjusting the angle of the rain shelter 20, the operator first holds the connecting rod 17 and slowly pulls it outward. During this process, the fixing pin 18 disengages from the connecting hole 13, while the limiting strip 19 slides smoothly inside the sliding groove 21. This provides precise guidance and protection for the unlocking action of the rain shelter 20, successfully unlocking it from the fixed angle. After unlocking, the rain shelter 20 can be easily rotated. The operator rotates the rain shelter 20 to a suitable angle for current use. Once the angle is adjusted, simply release both hands from the connecting rod 17. At this moment, driven by the spring 16, the connecting rod 17 moves inward, causing the fixing pin 18 to slide into the corresponding connecting hole 13. At this point, the angle adjustment of the rain shelter 20 is complete, providing reliable protection for subsequent use.
[0038] Working principle: When using the dustproof and heat-dissipating charging pile, the equipment starts charging the car by first starting the water pump 7, which drives the cooling water in the cooling water tank 6 to move. The cooling water first passes through the water pump 7 from the cooling water tank 6 into the input pipe 8, and then flows into the heat dissipation pipe 9, carrying away the heat generated by the power transmission device 5 during power transmission. After that, it flows into the return pipe 10 and returns to the cooling water tank 6 to continue the next cycle. When it is necessary to change the angle of the rain cover 20, first hold the connecting rod 17 and pull it outward, so that the fixing pin 18 is disengaged from the connecting hole 13. At the same time, the limiting strip 19 slides in the sliding groove 21, thereby unlocking the rain cover 20. Then, rotate the rain cover 20 to the required angle, and then release the connecting rod 17 so that it moves inward under the action of the spring 16, so that the fixing pin 18 slides into the corresponding connecting hole 13, thereby completing the change of the angle of the rain cover 20.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
