Technical Field
[0001] The utility model belongs to the field of charging piles, and in particular relates to a charging pile protection combined structure. Background Art
[0002] With the increasing number of new energy vehicles, the charging pile industry is becoming more and more prosperous. At present, there are many types of charging piles on the market, with many power types. The current technology of the charging pile industry is also relatively mature. However, the difficulties that plague the charging pile industry are also prominent, such as heat dissipation, dustproofing, and waterproofing. The following will explain dustproofing and waterproofing.
[0003] Since there are many charging modules and electronic components inside the charging pile, and these modules and components have strict requirements on the use environment, the protective structure of the charging pile is particularly important.
[0004] Regarding the dustproof performance of charging piles, most charging piles on the market currently use a single-layer dustproof cotton structure, but the types of dustproof cotton may be different; some charging piles use polyurethane dustproof cotton, and some charging piles use G4 dustproof cotton; the fixing methods of dustproof cotton are also very different. Most charging piles use sheet metal compression and then fix it with screws; some charging piles use a pulling dustproof cotton fixing method. Currently, charging piles on the market focus on these two types. At present, most of the charging piles using the above dustproof cotton structure are low-power charging piles, and the use scenarios of the charging piles are mostly concentrated in urban areas with good environmental conditions. If it is a high-power charging pile, at the same time, the use scenario is bad, such as coal mines, sandstone and steel mills, the above dustproof cotton structure cannot meet the needs of the use scenario, and the single-layer protection cannot well prevent the entry of dust. At the same time, the temperature rise inside the charging pile must be guaranteed, and it is difficult to find a balance between heat dissipation and dustproof performance. Generally speaking, the use scenarios of high-power charging piles are mostly concentrated in coal mines, sandstone and steel mills. These scenarios are all harsh environments with particularly high dustproof requirements, and the single-layer dustproof structure cannot meet the needs of the use scenario. If a single-layer dustproof structure is used, dust can easily enter the interior of the charging pile, which has a great impact on the charging module and electronic components inside the charging pile, affecting the performance of these components. At the same time, some simple shutter structures are used, including single-plate shutters, L-type shutters and S-type shutters, to achieve the purpose of protection. However, since this structure is too simple, it cannot be applied to the harsh adaptive environment of high-power charging piles, and the charging piles are prone to failure.
[0005] Regarding the waterproof performance of charging piles, most of the charging piles on the market currently do not have flow channels and do not pay special attention to the waterproof performance. For high-power charging piles, the operating environment is relatively harsh, and the waterproof performance needs special attention because there are more charging modules and electronic components inside the charging piles.
[0006] At present, most of the protective combination structures on the market adopt the above combination structure, which cannot be used for high-power charging piles and cannot guarantee their dustproof and waterproof performance. Therefore, the above technical status quo cannot be applied to high-power charging piles. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a charging pile protection combination structure includes a hexagonal hole structure 1 arranged on a cabinet door 10, and a shutter structure 2 is arranged on the inner side of the cabinet door. The shutter structure 2 is composed of a Z-shaped shutter blade 3. A double-layer dustproof cotton structure 11 is respectively installed above and below the back of the shutter structure 2, and each double-layer dustproof cotton structure 11 includes: a first layer of dustproof cotton limiter 4, a first layer of dustproof cotton 5, a second layer of dustproof cotton limiter 7, and a second layer of dustproof cotton 8, wherein the first layer of dustproof cotton 5 is installed in the first layer of dustproof cotton limiter 4, and the second layer of dustproof cotton 8 is installed in the second layer of dustproof cotton limiter 7. The first layer of dustproof cotton limiter 4 and the second layer of dustproof cotton limiter 7 are both sheet metal, and the two are fixed as a whole by welding, and there is a gap between the first layer of dustproof cotton 5 and the second layer of dustproof cotton 8, that is, a dust drop groove 6, to achieve the purpose of dustproof and waterproof.
[0025] It should be noted that the first layer dustproof cotton limiter 4 and the second layer dustproof cotton limiter 7 are formed of a groove structure by sheet metal, including upper, lower, left and right limits, so that the dustproof cotton can be located in the dustproof limiter.
[0026] Furthermore, the double-layer dust-proof cotton structure 11 is fixed to the shutter structure 2 by means of the buckle 12 , thereby achieving the purpose of fixing the double-layer dust-proof cotton structure 11 .
[0027] A double-layer dustproof cotton structure flow channel 9 is welded at the lower end of the double-layer dustproof structure 11, the bottom of the double-layer dustproof cotton structure flow channel 9 is inclined, a waist hole is arranged in the louver structure 2, and the bottom of the double-layer dustproof cotton structure flow channel 9 is connected to the waist hole.
[0028] Better, the double-layer dust-proof cotton structure flow channel 9 is arranged at the bottom of the first layer of dust-proof cotton limiter 4 and the second layer of dust-proof cotton limiter 7, and drainage holes are opened on the bottom sheet metal of the first layer of dust-proof cotton limiter 4 and the second layer of dust-proof cotton limiter 7, and the double-layer dust-proof cotton structure flow channel 9 is arranged below the drainage holes, and the double-layer dust-proof cotton structure flow channel 9 is welded to the louver structure 2, and the double-layer dust-proof cotton structure flow channel 9 and the louver structure 2 are welded as a whole, and a waist hole is opened on the louver structure 2 at the connection between the two, so that the water in the double-layer dust-proof cotton structure flow channel 9 can be discharged into the louver structure 2, and then discharged to the outside of the cabinet.
[0029] Furthermore, the hexagonal hole structure 1 can be processed on the cabinet door 10 by a CNC punching machine or laser cutting. This part of the structure serves as the first protective barrier of the charging pile, which can prevent large particles of dust and impurities from entering the charging pile.
[0030] Furthermore, a louver structure 2 is installed on the inner side of the cabinet door. The louver structure 2 is composed of an arrangement and combination of Z-shaped louvers 3. There is a degree of overlap between the Z-shaped louvers 3. The two Z-shaped louvers 3 form an inner buckle structure, which can prevent larger dust and impurities from entering the charging pile. At the same time, it can also achieve the purpose of waterproofing. The louver structure 2 is fixed to the cabinet door by bolting with bolts and nuts.
[0031] like Figure 5 As shown, each Z-type louver 3 includes a Z-type louver body, which is composed of a first blade 31, a second blade 32 and a third blade 33 to form a Z shape, wherein ear plate folds 35 are provided on both sides of the second blade 32, the ear plate folds 35 are arranged perpendicular to the second blade 32, and the ear plate folds 35 on each side are fixed to the protective frame on the corresponding side by rivets 36.
[0032] Furthermore, a bending edge 34 is provided at the end of the third blade 33 in each Z-shaped louver body, and an angle of 105° is provided between the bending edge 34 and the third blade 33, and a through hole is provided on the bending edge 34, and the first blade in another Z-shaped louver is inserted into the through hole, so that two adjacent Z-shaped louvers overlap with each other.
[0033] Preferably, the overlap between the third blade of the preceding Z-shaped louver and the first blade of the succeeding Z-shaped louver is 15 mm.
[0034] Thus, the Z-shaped louver structure of the charging pile is formed: Each Z-shaped louver 3 is arranged in combination, and after the arrangement and combination, there is a degree of overlap between the three adjacent Z-shaped louvers, ensuring that the overlap between the three Z-shaped louvers assembled up and down is 15mm. The ear plate folding edges 35 on both sides of each Z-shaped louver 3 are assembled with the protective frame and fixed with rivets 36. Two rivets 36 on one side are fixed to ensure fastening and structural strength. In the Z-shaped louver structure thus formed, each two Z-shaped louver 3 form an inner buckle. From the outside of the louver, the other side of the louver cannot be directly seen. The inner buckle structure of the louver prevents impurities, dust and water in the outside from directly entering the interior of the charging pile; at the same time, light cannot directly penetrate into the interior of the charging pile, avoiding direct sunlight on the electronic components and charging modules inside the charging pile, and avoiding failures of the electronic components and charging modules.
[0035] The working principle of the utility model is:
[0036] The operating environment of high-power charging piles is relatively harsh, and the particle sizes of dust and impurities are irregular and of varying sizes, so it is best to use a graded approach for protection. For charging piles, the protective structures of charging piles are mostly assembled on the cabinet door. First, the first layer of protection is to design a hexagonal hole structure 1 on the cabinet door 10 to prevent large particles of dust and impurities from entering the interior of the charging pile. Secondly, the second layer of protection is to design a louver structure 2 on the inside of the cabinet door 10. The louver structure 2 is used as the second layer of protection because the Z-shaped louver blades 3 of the louver structure 2 overlap each other, and the two Z-shaped louvers form an inner buckle structure, which can prevent larger dust and impurities from entering the interior of the charging pile. Finally, the third layer of protection is to design a double-layer dustproof cotton structure on the back side of the louver structure 2 to prevent small dust, impurities and dust from entering the interior of the charging pile, so as to avoid a great impact on the charging module and electronic components inside the charging pile, and affect the performance of these components.
[0037] Regarding the waterproof performance of the high-power charging pile, first, a flow channel structure is added to the louver structure 2. Part of the water that comes in through the hexagonal holes of the cabinet door will be blocked on the outside due to the inner buckle structure of the louver structure 2. The water between the hexagonal holes of the cabinet door and the louver structure will flow to the bottom along the louver, flow out through the flow channel structure of the louver structure 2 itself, and then flow out through the hexagonal holes at the bottom of the cabinet door. Second, a double-layer dust-proof cotton structure flow channel 9 is provided at the bottom of the double-layer dust-proof cotton structure 11. Part of the water that passes through the louver structure 2 will be blocked on the outside due to the first layer of dust-proof cotton 5. This part of the water will flow into the double-layer dust-proof cotton structure flow channel 9 through the hole at the bottom of the first layer of dust-proof cotton limiter 4, and then be discharged into the louver structure, and flow out through the flow channel at the bottom of the louver structure. A small amount of water that passes through the first layer of dustproof cotton 5 is blocked on the outside by the second layer of dustproof cotton 8. This part of water will flow through the gap between the double layers of dustproof cotton (dust-falling groove 6) into the double-layer dustproof cotton structure flow channel 9, be discharged into the louver structure 2, and flow out through the flow channel at the bottom of the louver structure. Finally, a very small amount of water can pass through the second layer of dustproof cotton 8, and the water that passes through the second layer of dustproof cotton 8 flows into the double-layer dustproof cotton structure flow channel 9, be discharged into the louver structure 2, and flow out through the flow channel at the bottom of the louver structure 2.
[0038] The utility model can be well suitable for high-power charging piles and can better adapt to the use environment of high-power charging piles.
[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that those skilled in the art can make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
