[0026] In order to make the content of the utility model more easily be clearly understood, the utility model is further explained in detail below according to specific embodiment and in conjunction with the drawings.

[0027] As Figures 1-4 Indicated, a ventilation protection structure of charging equipment includes:

[0028] Shell 1, the middle part of shell 1 is equipped with ventilation area, and the two side walls and top edge wall of shell 1 extend to form installation abutting edge to the periphery, wherein at least one installation abutting edge is spaced apart and arranged with at least one fixed stud along the length direction thereof;

[0029] Inner sealing strip 2, inner sealing strip 2 is annularly arranged on the installation abutting edge of shell 1;

[0030] Louver assembly 3, louver assembly 3 is installed in shell 1;

[0031] Cover plate 5, cover plate 5 is equipped with at least one ventilation hole, and cover plate 5 is provided with installation through hole corresponding to fixed stud, and cover plate 5 is suitable for being detachably connected with fixed stud through fastener;

[0032] Outer sealing strip 4, outer sealing strip 4 is arranged between louver assembly 3 and cover plate 5;

[0033] The dustproof cotton 6 is arranged between the outer sealing strip 4 and the outer cover plate 5.

[0034] In this embodiment, as shown in Figures 1-4 the installation process, first, the louver assembly 3, the outer sealing strip 4 and the dustproof cotton 6 are sequentially installed into the housing 1, then the inner sealing strip 2 is installed on the peripheral installation abutting edge of the housing 1, and finally the outer cover plate 5 is installed. The outer cover plate 5 is attached to the upper housing 1 provided with the inner sealing strip 2 using a fastener. The outer sealing strip 4 arranged on the louver assembly 3 avoids the gap problem caused by the processing method of the punched louver, thereby improving the protection performance of the equipment. During the operation of the equipment, external air can enter through the ventilation holes in the outer cover plate 5, and the porous structure of the dustproof cotton 6 can effectively block water droplets, dust and other impurities from entering the interior of the equipment. When liquid splashes in, the water absorption of the dustproof cotton 6 can reduce the direct entry of the liquid, and the liquid flows downward along the fiber structure of the dustproof cotton 6. Since the flow guide structure of the bottom wall 11 of the housing 1 is outwardly inclined, the liquid is finally smoothly discharged, thereby preventing internal water accumulation from damaging the equipment. In addition, the abutting edge of the louver assembly 3 is tightly attached to the outer sealing strip 4, so that the flow path of the liquid is controlled and limited within the flow path of the dustproof cotton 6 and the flow guide path of the bottom wall 11. The overall structure not only has good waterproof and dustproof effects, but also ensures the normal ventilation and heat dissipation requirements of the equipment, thereby improving the reliability and durability in outdoor environments.

[0035] Specifically, as shown in Figure 1 and Figures 3-4 the housing 1 further includes a bottom wall 11, and the space surrounded by the bottom wall 11, the two side walls and the top edge wall constitutes a water isolation chamber. The bottom surface of the bottom wall 11 is inclined downward from the inner side to the outer side of the housing 1 to form a flow guide structure.

[0036] Specifically, as shown in Figure 1 and Figure 4 the bottom wall 11 is located below the louver assembly 3, and a drainage gap is provided between the bottom wall 11 and the lower edge of the louver assembly 3.

[0037] In this embodiment, as shown in Figures 1-2 and Figure 4 the dustproof cotton 6 has a honeycomb-shaped porous structure inside. When water flows along the porous structure, part of it flows out of the ventilation holes of the outer cover plate 5, and the other part enters the water isolation chamber. The water entering the water isolation chamber is guided downward by the inclined flow guide structure of the bottom wall 11 and discharged to the outside of the equipment through the drainage gap. The inclination angle of the flow guide structure is 5°.

[0038] The drainage gap between the bottom wall 11 and the lower edge of the louver assembly 3 can ensure smooth drainage of water. Some water droplets that pass through the dustproof cotton 6 will be blocked by the louver assembly 3, and the water droplets will flow downward along the surface formed by the vertical section and the inclined section of the louver blade. This part of the water droplets will eventually be discharged outside the device through the drainage gap between the louver assembly 3 and the bottom wall 11. The outer sealing strips 4 on both sides of the louver assembly 3 work together to limit the flow path of water to the installation area of the dustproof cotton 6 and the drainage structure of the bottom wall 11.

[0039] Specifically, as shown in Figure 1 and Figures 3-4 , the shell 1 includes a ventilation panel, the ventilation panel includes an edge region and a middle region, wherein the edge region is integrally formed with the two side walls, the top edge wall and the bottom wall 11 of the shell 1, and the middle region is provided with a ventilation opening, and the ventilation opening is a ventilation area of the shell 1.

[0040] In this embodiment, as shown in Figure 1 and Figures 3-4 , the ventilation panel of the shell 1 adopts an integrally formed structure design. The edge region is connected with the two side walls, the top edge wall and the bottom wall 11 of the shell 1 to form a whole, avoiding the gap that may be caused by the assembly of multiple parts. The ventilation opening in the middle region serves as the ventilation area of the shell 1, providing a channel for air flow between the inside and outside of the device.

[0041] In actual application, air enters the inside of the device through the ventilation opening. When external water droplets enter, the water droplets enter the edge region at most, and are finally discharged along the vertical path by gravity.

[0042] Specifically, as shown in Figures 1-2 , the ventilation holes on the cover plate 5 are arranged in horizontal and vertical directions.

[0043] Specifically, as shown in Figure 1 and 4 , the louver assembly 3 is a punched louver.

[0044] Specifically, as shown in Figure 1 and 4 , the louver assembly 3 includes a plurality of louver blades arranged in a vertical direction, each louver blade includes a vertical section and an inclined section, the upper end of the inclined section is connected with the lower end of the vertical section, and the lower end of the inclined section extends outward and downward.

[0045] In this embodiment, as shown in Figures 1-4 , the louver assembly 3 is formed by a punching process. When water droplets enter, the water droplets flow downward along the surface of the vertical section of the louver blade, and then are guided outward through the inclined section.

[0046] The stamping forming of the louver assembly 3 forms ventilation gaps between the louver blades. These gaps can ensure air circulation and control water droplets from entering through cooperation with the dustproof cotton 6. When water droplets pass through the gaps, part of them will flow along the surface of the louver blades, and the other part will be absorbed by the dustproof cotton 6. The moisture absorbed by the dustproof cotton 6 flows downward along its internal structure and is finally discharged through the bottom wall 11. There is generally a gap of 1-2 mm between the stamped louver blades. In outdoor use scenarios, only the stamped louver blades will have the situation of water droplets splashing into through the gaps, and it is impossible to completely isolate all liquids, so the dustproof cotton 6 and the outer sealing strip 4 are installed between the outer cover plate 5 and the stamped louver assembly 3.

[0047] In other embodiments, the inner sealing strip 2 and the outer sealing strip 4 can be made of elastic materials such as rubber, which are tightly fitted with adjacent components through elastic deformation. The mounting abutting edge of the shell 1 is detachably connected with the outer cover plate 5 through fixing studs and fasteners, which is convenient for later maintenance. The louver assembly 3 formed by the stamping process can ensure the size accuracy through the mold, and compared with the traditional welding process, it has the characteristics of high material utilization rate and no cutting in the processing process. The overall structure is fixed and connected between the components through screws, and cooperates with the setting of the sealing strip, so that the moisture only flows in the dustproof cotton 6 area and the bottom wall 11 flow guide structure.

[0048] The above-described specific embodiments further illustrate the technical problems solved by the present application, technical solutions and beneficial effects. It should be understood that the above-described specific embodiments are only specific embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
