[0002] Electric vehicle charging stations are a new type of environmentally friendly facility that provides power to electric vehicles. The core equipment is the charging stack. The modular design of the charging stack makes it flexible in its composition. Battery units can be added or removed according to actual needs, thereby adjusting the amount of electrical energy stored. Modular charging stacks are more convenient and economical to expand and upgrade. In addition, the charging stack can support multiple charging channels for different vehicle models at the same time, improving the utilization rate and service efficiency of the charging station.

[0003] Existing high-power dynamic charging pile structures are mainly used outdoors, so they need to cope with various weather conditions. If the charging pile is not waterproof, rainwater will enter the charging pile along with the air through the air inlet. Once the electrical components get damp, it may cause short circuits or corrosion, reduce the service life of the equipment, and increase maintenance costs. Utility Model Content

The existing high-power dynamic charging pile structures are mainly used outdoors and need to cope with various weather conditions. If the waterproof effect of the charging pile is not good, rainwater will enter the charging pile with the air from the air inlet. Once the electrical components are damp, it may cause short circuit risks or corrosion, reduce the service life of the equipment, and increase maintenance costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-power dynamic charging pile structure, including a shell, an air inlet assembly, an AC input module, a fuel cell module, an air outlet assembly, and a DC output module.

The air inlet assembly includes an air inlet plate, a drain bracket, and an air inlet louver plate. The air inlet plate is connected to the shell, and the drain bracket is fixedly connected to the side of the air inlet plate near the inside of the shell. An air inlet louver plate is disposed above the drain bracket. An air inlet hole is opened at the upper position of the air inlet plate, and an external drain hole is opened at the lower position of the air inlet plate. The height of the air inlet hole corresponds to the height of the air inlet louver plate, and the height of the external drain hole corresponds to the height of the drain bracket.

[0006] Preferably, multiple sets of the air inlet louvers are arranged on the drain bracket. The air inlet louvers include a folding frame and a baffle. One side of the folding frame is concave and the other side is convex. The baffle is connected to one side of the convex surface of the folding frame. The folding frame and the baffle are at the same height.

[0007] Preferably, the folding trend of the cross-section of the folding frame is half of the octagonal border, the opening direction of the folding frame is parallel to the surface of the air inlet plate, the baffle is located in the center of the folding frame, and the direction of its facade is parallel to the surface of the air inlet plate.

[0008] Preferably, the drain bracket includes a grid plate, an internal drain frame, and a drain trough. The grid plate is fixedly connected to the air inlet plate.

[0013] This invention utilizes the arrangement of air inlet louvers and drainage brackets. Multiple air inlet louvers are combined and distributed, along with the design of a folding frame and baffles. Airflow within the air inlet louver area repeatedly collides with the surfaces of the folding frame and baffles. Even if rainwater enters from the outlet, after colliding with the surfaces of the folding frame and baffles, the rainwater droplets fall along the vertical surface of the air inlet louvers under gravity onto the grid horizontal plate. Finally, the rainwater droplets collect in the drainage channel and are promptly discharged from the external drainage hole into the housing. This device effectively blocks rainwater in this area while ensuring normal airflow into the housing, reducing the risk of short circuits or corrosion caused by moisture in electrical components, extending the device's service life, and lowering maintenance costs.

Detailed Implementation

[0022] 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.

[0023] One embodiment of this utility model provides: a high-power dynamic charging pile structure, such as... Figure 1 As shown, it includes a housing 1, an air inlet assembly 2, an AC input module 3, a fuel cell stack module 4, an air outlet assembly 5, and a DC output module 6.

[0024] like Figure 1 As shown, the AC input module 3, the fuel cell stack module 4, and the DC output module 6 are housed inside the casing 1. Figure 1 and Figure 2 As shown, the air inlet assembly 2 and the air outlet assembly 5 are fixed to the housing 1. Air from outside the housing 1 enters the housing 1 through the air inlet assembly 2. The air passes through the channels provided by the AC inlet module 3, the fuel cell module 4, and the DC outlet module 6 inside the housing 1, and passes through the fuel cell module 4 to achieve heat exchange between the air and the heating element. The air temperature will increase as it passes through the fuel cell module 4. Finally, the hot air is discharged from the air outlet plate 51 to the outside of the housing 1 by the air outlet fan 52 of the air outlet assembly 5.

[0025] like Figure 3 As shown, the front of the housing 1 is equipped with an equal number of indicator lights 11 as the number of charging guns, and each indicator light 11 displays the status of the corresponding charging gun.

[0026] like Figure 4 As shown, the air intake assembly 2 includes an air intake plate 21, a drain bracket 22, an air intake louver plate 23, a filter screen 24, and a cooler 25. The air intake plate 21 is connected to the housing 1, and the drain bracket 22 is fixedly connected to the side of the air intake plate 21 near the inside of the housing 1.

[0027] An air inlet louver plate 23 is installed above the drain bracket 22. For example... Figure 6 As shown, an air inlet hole 211 is provided at the upper position of the air inlet panel 21. The height position of the air inlet hole 211 corresponds to the air inlet louver panel 23. Multiple sets of air inlet louver panels 23 are arranged on the drain bracket 22. The air passing through the air inlet assembly 2 first passes through the air inlet panel 21, and then through the channels arranged in the air inlet louver panels 23.

[0028] The air inlet louver panel 23 includes a folding frame 231 and a baffle 232. One side of the folding frame 231 is concave, and the other side is convex. The baffle 232 is connected to the convex side of the folding frame 231, and the folding frame 231 and the baffle 232 are at the same height. The combination and distribution of multiple air inlet louver panels 23, combined with the shape of the folding frame 231 and the baffle 232, increases the airflow trajectory in the area of ​​the air inlet louver panel 23. Since this device is used outdoors and needs to cope with various weather conditions, the folding frame 231 and baffle 232 reduce the risk of rainwater directly entering the housing 1. Air flows through the air inlet louver plate area 23 and repeatedly collides with the surfaces of the folding frame 231 and baffle 232. Even if rainwater enters from the air inlet plate 21, it will flow downwards under gravity after colliding with the surfaces of the folding frame 231 and baffle 232. The rainwater is effectively blocked in this area by the air inlet louver plate 23, while ensuring that heat dissipation air can enter the housing normally. This improves the protection of the electrical components inside the housing 1, effectively waterproofs them, reduces the risk of short circuits or corrosion caused by moisture in the electrical components, extends the service life of the device, and reduces maintenance costs.

[0029] The folding trend of the cross-section of the folding frame 231 is half of the frame of a regular octagon. The opening direction of the folding frame 231 is parallel to the surface of the air inlet panel 21. The baffle 232 is located in the center of the folding frame 231, and its facade is parallel to the surface of the air inlet panel 21. With the angle setting of each fold of the folding frame 231 and the baffle 232, the airflow through the area of ​​the air inlet louver panel 23 will first hit the inclined surface, change the airflow direction, and then continue to change the airflow direction three times, finally leaving the area of ​​the air inlet louver panel 23. After the air carrying rainwater comes into contact with the facade of the air inlet louver panel 23 multiple times, most of it will be absorbed onto the air inlet louver panel 23. With the accumulation of rainwater droplets and the effect of gravity, the rainwater droplets fall down along the facade of the air inlet louver panel 23.

[0030] Both ends of the folding frame 231 are provided with raised edges, and the end of the baffle 232 is also provided with raised edges. The raised edges increase the airflow trajectory through the area of ​​the air inlet louver plate 23.

[0031] like Figure 5 As shown, the drain bracket 22 includes a grid horizontal plate 221, an internal drain frame 222, and a drain groove 223. The grid horizontal plate 221 is fixedly connected to the air inlet plate 21. The internal drain frame 222 is connected to the lower part of the grid horizontal plate 221. Both the grid horizontal plate 221 and the internal drain frame 222 have slots. The drain groove 223 is connected to the lower part of the internal drain frame 222. The bottom surface of the drain groove 223 is inclined, and the inclined lower end is attached to the air inlet plate 21. The area of ​​the drain groove 223 corresponds in height to the external drain hole 212. Figure 6As shown, an external drain hole 212 is provided at the lower position of the air inlet plate 21, and the height position of the external drain hole 212 corresponds to the drain bracket 22.

[0032] Rainwater droplets falling along the facade of the air inlet louver panel 23 land on the grille horizontal plate 221, then fall through the slots in the grille horizontal plate 221 into the inner drain rack 222. The slots in the inner drain rack 222 are larger, allowing the rainwater droplets to continue falling into the drain trough 223. Due to the inclined surface of the drain trough 223, the rainwater collected in the drain trough 223 flows out of the housing 1 through the external drain hole 212, effectively draining the liquid intercepted by the air inlet louver panel 23. A rubber strip is installed between the inclined lower end of the drain trough 223 and the air inlet panel 21 to prevent the collected rainwater from seeping into the interior of the housing 1.

[0033] like Figure 4 and Figure 5 As shown, the air intake assembly 2 also includes a filter screen 24, and the drain bracket 22 also includes a filter screen connecting groove 224. The bottom of the filter screen 24 is inserted into the filter screen connecting groove 224, and the air after intercepting rainwater will continue to enter the interior of the housing 1 through the filter screen 24.

[0034] like Figure 7 As shown, a cooler 25 can also be installed above the air inlet louver panel 23. The cooler 25 includes a refrigeration component 251 and a coolant tank 252. The refrigeration component 251 is connected to the coolant tank 252. The bottom of the coolant tank 252 is provided with a slot 2521 that matches the air inlet louver panel 23. The air inlet louver panel 23 is plugged into the slot 2521. The cooling component 251 can cool the liquid in the coolant tank 252. The air inlet louver 23 is made of a material that conducts heat easily. The coolant tank 252 can transfer the cooled temperature to the top of the air inlet louver 23. The cooled temperature of the air inlet louver 23 then diffuses downwards. If the humidity of the air passing through is high, the air inlet louver 23, which is cooler than the outside environment, will condense into small water droplets through repeated collisions and accumulate and flow down. This allows the air inlet louver 23 area to not only isolate rainwater in rainy weather, but also reduce the humidity of the air entering the housing 1 in humid weather. This reduces the impact of the humid air on the electrical components inside the housing 1, reduces the risk of short circuits or corrosion caused by moisture in the electrical components, extends the service life of the device, and reduces maintenance costs.

[0035] like Figure 1As shown, air enters the interior of the housing 1 through the air inlet louver plate 23 area. Before passing the fuel cell stack module 4, it flows in the channel between the fuel cell stack module 4 and the housing 1. An air guide 12 is provided in the channel. The side of the air guide 12 facing the fuel cell stack module 4 has evenly spaced inclined surfaces. The air coming from the channel towards the air guide 12 is dispersed on each inclined surface. At the inclined surface, the air direction is changed and blows vertically towards the fuel cell stack module 4, so that the air passing through the fuel cell stack module 4 can be evenly distributed, increasing the ventilation efficiency and thus improving the heat exchange effect on the fuel cell stack module 4.

[0036] The above are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics in the solutions has not been described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
