Description

Technical Field

[0001] The present invention relates to the technical field of outdoor communication base station cabinets, and in particular to a cabinet door panel splicing waterproof structure, a splicing cabinet and a communication base station cabinet. Background Art

[0002] The roads in remote mountainous and forested areas are generally narrow and cannot accommodate large vehicles and machinery. Manual transportation to the installation site is often required. However, in order to achieve the IP55 protection level, the outdoor energy cabinets of base stations are generally processed by welding and then gluing. The structure cannot be disassembled and transported to the installation site for reassembly. The cabinets are large and heavy, making them inconvenient to transport and install in such an environment.

[0003] Operators have attempted to solve the above-mentioned disassembly and assembly technical problems. For example, CN116321879A discloses a modular cabinet for rapid installation of data communication components, including a cabinet body, support door panels are provided on the front and rear sides of the cabinet body, support side panels are provided on the left and right sides of the cabinet body, support mesh panels 30 are provided on the upper and lower sides of the cabinet body, the top of the cabinet body is connected to an upper guide box 2 through the support mesh panel 30, and the bottom of the cabinet body is connected to a lower guide box 3 through the support mesh panel 30. A rainproof top cover 1 is provided on the top of the upper guide box 2, and a rainproof corrugated cover 20 is provided inside the rainproof top cover 1. A first fan 5 is embedded in the bottom of the upper guide box 2, and a second fan 15 is embedded in the top of the lower guide box 3. A plurality of partition plates 7 are evenly distributed at equal distances from top to bottom in the cabinet body, and I-shaped support columns 6 are installed at the four corners of the partition plates 7. A wire management plate 13 is provided in the cabinet body and on the left and right sides of the partition plate 7, and a plurality of wire bundle plates 14 are installed on the wire management plate 13. The rainproof top cover 1 is installed on the top of the upper guide box 2 through a connecting column 31. A connecting ring plate 19 is sleeved on the lower end of the rainproof top cover 1 and the outer periphery of the upper end of the upper guide box 2. The connecting ring plate 19 is fixedly connected to the lower end of the rainproof corrugated cover 20. Positioning buckles 33 are fixedly connected to the four sides of the connecting ring plate 19. Buckles opposite to the positioning buckles 33 are installed around the four sides of the rainproof top cover 1 and the four sides of the supporting base plate 4. When strong winds and heavy rains come, the connecting ring plate 19 and the rainproof top cover 1 are separated by the positioning buckles 33, and the rainproof corrugated cover 20 is stretched downward from the rainproof top cover 1. Then, the connecting ring plate 19 is connected to the supporting base plate 4 through the positioning buckles 33, so that the rainproof corrugated cover 20 is limited by the rainproof top cover 1 and the supporting base plate 4, so that the rainproof corrugated cover 20 covers the outside of the cabinet to prevent wind and rain from entering the cabinet. When it rains, take out the rainproof corrugated cover 20 in the rainproof top cover 1 and cover the entire cabinet to quickly prevent rain. All components are made by modular processing and can be removed and replaced independently of each other. At the same time, by adjusting the length of the supporting door panel and the supporting side panel, the height of the entire cabinet can be adjusted modularly, making the cabinet suitable for different environments and meeting different communication equipment installation requirements.

[0004] Although CN116321879A can adapt to different environments, each component is manufactured by modular processing, can be removed and replaced independently, and has corresponding waterproof measures, its waterproof means is to "take out the rainproof corrugated cover 20 in the rainproof top cover 1 and cover the whole cabinet". It has the following problems:

[0005] External waterproof structure, the structural parts are large and complex, and the production cost is high;

[0006] Manually operated rainproof bellows, outdoor, especially in remote areas, requires a lot of manpower to manage these cabinets, which is impractical;

[0007] A sudden downpour will not give you enough time to prepare and open these rainproof bellows, and they are not able to keep out the rain at all.

[0008] Based on this, there is an urgent need for a cabinet door panel splicing waterproof structure, a splicing cabinet and a communication base station cabinet that are easy to disassemble and transport, do not change the cabinet protection performance, and ensure that the waterproof requirements are met. Summary of the invention

[0039] The present invention also provides a communication base station cabinet, comprising a bottom plate and a top plate.

[0040] The bottom plate is provided with adjacent door panels: a front panel 91, a left panel 92, a rear panel, and a right panel; the adjacent door panels are spliced ​​by the cabinet door panel splicing waterproof structure and then fixed by bolts, and the first splicing surface 1 has a side extension surface 16;

[0041] The communication base station cabinet is used to set at least one of the following communication equipment: 4G base station, 5G base station, 6G base station, base station energy equipment, network communication equipment

[0042] The beneficial effects of adopting the above technical solution are:

[0043] Most of the water that falls into the top guard plate 31 is blocked by the top guard plate and leaks out of the drainage channel 3. A very small part of the water generally drips into the drainage channel 3 in the form of water drops through the gap between the rear top guard surface 15 and the front top guard surface 24.

[0044] Water enters from the side gap 81 and flows into the drainage channel 3 through the first notch 51 in the following states:

[0045] One of the soft water flows into the side gap 81: such as light rain level water, the water speed is low, and the water speed is slowed down when it is sprayed into the high, deep and narrow gap between the side joint surface 22 and the right joint surface 11, and the water cannot reach the first gap 51 at all;

[0046] One of the waters with a certain jet force flows into the side gap 81: for example, water of medium rain level, with a moderate water speed, is sprayed into the high, deep and narrow gap between the side joint surface 22 and the right joint surface 11, and the water speed is slowed down. A very small part of the water flows back from the gap or flows downward when encountering a blockage, and the other part of the water turns right angles and enters the first gap 51 with difficulty. At this time, the water entering the first gap 51 no longer has a jet force, and the water flows from the first gap 51 downward along the inner wall of the drainage channel 3 into the drainage channel 3. The water flowing through the first gap 51 is not enough to spray to the opposite second gap 41;

[0047] One type of water with impact force rushes into the side gap 81: such as heavy rain, violent storms and water at the product testing level, with a relatively high water speed, and is sprayed into the high, deep and thin gap between the side joint 22 and the right joint 11, where the water speed is slowed down. A small part of the water moves forward with difficulty and then flows back from the gap or flows downward when encountering an obstruction, and the other part of the water turns at a right angle and enters the first gap 51 with difficulty. At this time, the water entering the first gap 51 has a certain jet force, and the water is discharged from the first gap 51 to the drainage channel 3 like water from a faucet. Since the side portions of the first gap 51 and the side portions of the second gap 41 are arranged on the left and right sides of the drainage channel 3 in a large and small, front and back, and staggered positions, the water passes through the larger first gap 51 and has its cross-sectional area enlarged to reduce the flow rate, and the water flowing through the first gap 51 is also not enough to be sprayed to the opposite second gap 41.

[0048] Even if water entering the first gap 51 or the gap between the top guard surface 15 and the front top guard surface 24 can spread to the area where the second gap is located, since the drainage channel 3 is enclosed in a relatively closed windless space by the first splicing surface 1 and the second splicing surface 2, the water spreading to the area where the second gap is located can only flow through the inner side of the second gap 41 and finally fall into the drainage channel 3, and the water does not flow through the second gap 41.

[0049] The cabinet door panel splicing waterproof structure is used for splicing adjacent door panels of the cabinet. A front top notch 5 including a first notch 51 is provided on the second splicing surface 2, and a rear top notch 4 including a second notch 41 is provided on the first splicing surface 1, thereby solving the technical problem that the splicing surfaces cannot be spliced ​​into place due to interference with each other due to dimensional errors in processing or errors in assembly angles during on-site assembly. In order to avoid mutual interference, the waterproof structure after splicing has the first notch 51, the second notch 41 and the top gap. Water entering from the top gap and the first notch 51 will not flow out of the second notch, but will only be discharged from the drainage channel 3 through the drainage trough. The waterproof level reaches the IPX5 waterproof level.

[0050] The spliced ​​cabinet can be transported to the installation point in a disassembled structure and then spliced ​​without moving the entire cabinet. It is especially suitable for installation environments such as mountains where it is difficult to transport the entire cabinet. The protective body of the cabinet is still composed of the bottom plate, top plate, front plate 91, left plate 92, rear plate and right plate. Therefore, the cabinet assembled on site does not change the protective performance of the cabinet. In order to avoid mutual interference during splicing, the waterproof structure after splicing has a first gap 51, a second gap 41 and a top gap. Water entering from the top gap and the first gap 51 will not flow out from the second gap, but will only be discharged from the drainage channel 3 through the drainage trough to discharge the cabinet. The waterproof level reaches IPX5 waterproof level.

[0051] The communication base station cabinet can be transported to the installation point in a disassembled structure and then assembled without the need to transport the entire cabinet. It is particularly suitable for installation environments such as mountains where it is difficult to transport the entire cabinet. The protective body of the communication base station cabinet is still composed of a bottom plate, a top plate, a front plate 91, a left plate 92, a rear plate and a right plate. Therefore, the cabinet assembled on site does not change the cabinet's protection performance to reach an IP55 protection level. Water entering from the top gap and the first notch 51 will not flow out from the second notch, but will only be discharged from the cabinet through the drainage channel 3 through the drainage trough, and the waterproof level reaches the IPX5 waterproof level.

[0067] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] Example 1.

[0069] Generally, the communication energy cabinet is a large and heavy rectangular body. When splicing the cabinet door panels on site, it is necessary to consider that the splicing between the door panels does not interfere with each other and the assembled cabinet reaches the corresponding waterproof level and protection level. It should be noted that the waterproof is mainly to prevent rainwater from entering the cabinet. In view of this, adjacent door panels are spliced ​​by a cabinet door panel splicing waterproof structure described in this application.

[0070] like Figure 1-8 A cabinet door panel splicing waterproof structure is shown. Figure 3 As shown, it includes a first splicing surface 1 and a second splicing surface 2 which are bent at multiple right angles and can be spliced ​​together;

[0071] like Figure 2 , 6 and Figure 7 As shown, the first splicing surface 1 and the second splicing surface 2 are spliced ​​together to form a drainage channel 3 that is an overall square. The bottom of the drainage channel 3 is connected to the drainage groove, and water is discharged from the drainage groove;

[0072] like Figure 1 and Figure 6 As shown, the first joint surface 1 and the second joint surface 2 are respectively provided with a rear top protection surface 15 and a front top protection surface 24 that cooperate with each other to avoid each other, and the rear top protection surface 15 and the front top protection surface 24 are spliced ​​to form a top protection plate 31 of the drainage channel 3;

[0073] Most of the water that falls into the top guard plate 31 is blocked by the top guard plate and leaks out of the drainage channel 3. A very small part of the water generally drips into the drainage channel 3 in the form of water drops through the gap between the rear top guard surface 15 and the front top guard surface 24.

[0074] The drainage channel 3 has a first notch 51: a notch with a side portion and a rear portion cut out from the top right corner of the second joint surface 2;

[0075] The drainage channel 3 has a second notch 41: a notch with a side portion and a front portion cut out from the top of the lower left corner of the first joint surface 1;

[0076] There may be dimensional errors during the processing of the splicing surface, and there may be errors such as assembly angles during on-site assembly, which will cause the splicing surfaces to interfere with each other and fail to be spliced ​​in place. In addition, considering that the bottom of the splicing surface needs to bear weight, the error operating space is set at the top of the splicing surface. In view of this, if Figure 3 As shown, the second joint surface 2 is provided with a front top notch 5 including the first notch 51 , and the first joint surface 1 is provided with a rear top notch 4 including the second notch 41 .

[0077] The side of the first notch 51 is larger than the side of the second notch 41;

[0078] After splicing, Figure 2 As shown, the first joint surface 1 has a right joint surface 11 and a rear joint surface 12, and the second joint surface 2 has an outer joint surface 21 and a side joint surface 22; a front waterproof strip 6 is provided between the outer joint surface 21 and the first joint surface 1, and a rear waterproof strip 7 is provided between the rear joint surface 12 and the second joint surface 2;

[0079] like Figure 2 , 6 , 7 and Figure 8 As shown, the rear of the first notch 51 is blocked by the rear waterproof strip 7, the side connection surface 22 and the side of the first notch 51 are surrounded by the right connection surface 11 and the rear top protection surface 15, and the front of the second notch 41 is blocked by the front waterproof strip 6. The side of the first notch 51 and the side of the second notch 41 are arranged in staggered positions on the left and right sides of the drainage channel 3, one large and one small, one front and one back.

[0080] The water that affects the waterproof structure is generally rainwater. Rainwater enters from the side gap 81 through the first notch 51 and flows into the drainage channel 3 in the following states:

[0081] One of the soft water flows into the side gap 81: such as light rain level water, the water speed is low, and the water speed is slowed down when it is sprayed into the high, deep and narrow gap between the side joint surface 22 and the right joint surface 11, and the water cannot reach the first gap 51 at all;

[0082] One of the waters with a certain jet force flows into the side gap 81: for example, water of medium rain level, with a moderate water speed, is sprayed into the high, deep and narrow gap between the side joint surface 22 and the right joint surface 11, and the water speed is slowed down. A very small part of the water flows back from the gap or flows downward when encountering a blockage, and the other part of the water turns right angles and enters the first gap 51 with difficulty. At this time, the water entering the first gap 51 no longer has a jet force, and the water flows from the first gap 51 downward along the inner wall of the drainage channel 3 into the drainage channel 3. The water flowing through the first gap 51 is not enough to spray to the opposite second gap 41;

[0083] One type of water with impact force rushes into the side gap 81: such as heavy rain, violent storms and water at the product testing level, with a relatively high water speed, and is sprayed into the high, deep and thin gap between the side joint 22 and the right joint 11, where the water speed is slowed down. A small part of the water moves forward with difficulty and then flows back from the gap or flows downward when encountering an obstacle, and the other part of the water turns at a right angle and enters the first gap 51 with difficulty. At this time, the water entering the first gap 51 has a certain jet force, and the water is discharged from the first gap 51 to the drainage channel 3 like water from a faucet. Since the side portions of the first gap 51 and the side portions of the second gap 41 are arranged on the left and right sides of the drainage channel 3 in a large and small, front and back, and staggered positions, the water passes through the larger first gap 51 and the cross-sectional area is enlarged to reduce the flow rate, and the water flowing through the first gap 51 is also not enough to be sprayed to the opposite second gap.

[0084] Even if water entering the first gap 51 or the gap between the top guard surface 15 and the front top guard surface 24 can spread to the area where the second gap is located, since the drainage channel 3 is enclosed in a relatively closed windless space by the first splicing surface 1 and the second splicing surface 2, the water spreading to the area where the second gap is located can only flow through the inner side of the second gap 41 and finally fall into the drainage channel 3, and the water does not flow through the second gap 41.

[0085] Please refer to the following waterproof test table for the waterproof test results corresponding to the notch settings.

[0086]

[0087]

[0088] Combined with the above waterproof test table, the side of the first notch 51 and the side of the second notch 41 are arranged in a staggered position on the left and right sides of the drainage channel 3 in a large and small, front and back manner, which can effectively prevent water, and the waterproof level reaches IPX5 waterproof level.

[0089] The cabinet door panel splicing waterproof structure is used for splicing adjacent door panels of the cabinet. A front top notch 5 including a first notch 51 is provided on the second splicing surface 2, and a rear top notch 4 including a second notch 41 is provided on the first splicing surface 1, thereby solving the technical problem that the splicing surfaces cannot be spliced ​​into place due to interference with each other due to dimensional errors in processing or errors in assembly angles during on-site assembly. In order to avoid mutual interference, the waterproof structure after splicing has the first notch 51, the second notch 41 and the top gap. Water entering from the top gap and the first notch 51 will not flow out of the second notch, but will only be discharged from the drainage channel 3 through the drainage trough. The waterproof level reaches the IPX5 waterproof level.

[0090] Example 2. Figure 3-5 Showing the first joint surface 1 and the second joint surface 2:

[0091] The first joint surface 1 includes the right joint surface 11, the rear joint surface 12, the left joint surface 13, the front joint surface 14 and the rear top protection surface 15;

[0092] The second joint surface 2 includes the outer connecting surface 21, the side connecting surface 22, the inner connecting surface 23 and the front top protecting surface 24;

[0093] The front waterproof strip 6 is provided between the front connecting surface 14 and the outer connecting surface 21, and the rear waterproof strip 7 is provided between the rear connecting surface 12 and the inner connecting surface 23;

[0094] In order to facilitate splicing, the front waterproof strip 6 is generally arranged behind the external connection surface 21, and the rear waterproof strip 7 is arranged in front of the rear connection surface 12 before splicing;

[0095] Of course, the front waterproof strip 6 can also be arranged in front of the front connecting surface 14, and the rear waterproof strip 7 can be arranged behind the inner connecting surface 23 before splicing, but this method requires a higher assembling angle.

[0096] The side surface 22 is the right inner side surface 32 of the drainage channel 3 .

[0097] Example 3. Figure 1 , 2 , 6 and Figure 7 Show the gaps and waterways of the waterproof structure:

[0098] The right joint surface 11 and the side joint surface 22 after being spliced ​​form a side gap 81 with a depth equal to the width of the right joint surface 11 and a height equal to the height of the right joint surface 11;

[0099] The rear connecting surface 12 and the inner connecting surface 23 form a rear slit 82, one end of which is connected to the side slit 81 but blocked by the rear waterproof strip 7, and the other end of which is connected to the drainage channel 3;

[0100] The side of the first notch 51 is connected to the side gap 81 and the drainage channel 3 to form a top water inlet gap 83, and the rear is blocked by the rear waterproof strip 7;

[0101] The side of the second notch 41 is connected to the drainage channel 3 to form a top water-proof gap 84, and the front is blocked by the front waterproof strip 6;

[0102] The front connecting surface 14 and the outer connecting surface 21 form a front gap 85 which is in communication with the drainage channel 3 but is blocked by the front waterproof strip 6;

[0103] The rear top protection surface 15 and the front top protection surface 24 form a top gap 86 communicating with the drainage channel 3 .

[0104] The first water path: water enters the drainage channel 3 from the top gap 86 of the top guard plate 31. When the water entering the drainage channel 3 flows through the front gap 85, it is blocked by the front waterproof strip 6 and cannot be discharged from the gap. The water is finally discharged through the drainage groove.

[0105] The second waterway: water enters from the side gap 81. When turning at a right angle, one of the rear gaps 82 is blocked by the rear waterproof strip 7 so that water cannot enter. The other top water inlet gap 83 introduces water into the drainage channel 3. When the water entering the drainage channel 3 flows through the front gap 85, it is blocked by the front waterproof strip 6 and cannot be discharged from the gap. The water is finally discharged through the drainage trough.

[0106] Please refer to the following waterproof test table for the waterproof test results corresponding to the notch settings.

[0107]

[0108]

[0109] Combined with the above waterproof test table, the top water inlet gap and the top water avoidance gap are arranged in a staggered position with one large and one small, one front and one back on the left and right sides of the drainage channel 3, which can effectively prevent water, and the waterproof level reaches IPX5 waterproof level.

[0110] Example 4. Figure 8 Show notch parameters:

[0111] The second notch 41 has a length of L1, a width of W1, and a height of H1; the first notch 51 has a length of L2, a width of W2, and a height of H2;

[0112] The length of the front top notch 5 is the same as the length of the front top protection surface 24, which is L3; the left width is W3; the right width is the same as the width of the first notch 51, which is W2; and the height is the same as the height of the first notch 51, which is H2;

[0113] The length of the rear top notch 4 is the same as the length of the rear top protection surface 15 , which is L4 ; the left width is the same as the width of the second notch 41 , which is W1 ; the right width is W4 ; and the height is the same as the height of the second notch 41 , which is H1 .

[0114] Example 5. Figure 1-8 As shown, in order to avoid mutual interference between the first splicing surface 1 and the second splicing surface 2 when splicing, W3 = W6, W1 <W4,W2<W3,L1+L2<L3,L1+L2<L4。

[0115] Example 6. Figure 1-8 As shown, in order to enlarge the top water inlet gap 83 to reduce the flow rate without generating direct spray, W2>W1, H2>H1.

[0116] Example 7. Figure 1-8 As shown, in order to make the first splicing surface 1 and the second splicing surface 2 fit tightly after splicing, L3=L4, W3=W6, W4=W5, W1+W2 <W5+W6。

[0117] Example 8. Figure 1-8 As shown, the thicknesses of the front waterproof strip 6 and the rear waterproof strip 7 after being assembled and pressed are W7 and W8 respectively, W1+W2+W7+W8=W5+W6.

[0118] Example 9. Figure 1-3 as well as Figure 8 A spliced ​​cabinet is shown, including a bottom plate and a top plate, wherein the bottom plate is provided with adjacent door panels: a front plate 91, a left side plate 92, a rear plate, and a right side plate; the adjacent door panels are spliced ​​by the cabinet door panel splicing waterproof structure and then fixed with bolts, and the first splicing surface 1 also has a side extension surface 16.

[0119] The first splicing surface 1 is bent at multiple right angles from the side extension surface 16 to form the first splicing surface 1 that can be spliced ​​with the second splicing surface 2 .

[0120] Take the splicing of the cabinet front panel 91 and the left side panel 92 as an example:

[0121] The front plate 91 has a first joint surface 1, and the left side plate 92 has a second joint surface 2;

[0122] Before the door panels are assembled, the front panel 91 is fixed to the bottom panel;

[0123] During splicing, the second splicing surface 2 of the left side plate 92 is pushed toward the first splicing surface 1 of the front plate 91;

[0124] The rear top protection surface 15 and the front top protection surface 24 are spliced ​​to form the top protection plate 31 of the drainage channel 3;

[0125] The external connection surface 21, the front waterproof strip 6 and the first joint surface 1 are in abutment with each other;

[0126] The rear joint surface 12, the rear waterproof strip 7 and the second joint surface 2 are in abutment with each other;

[0127] The side joint surface 22 and the right joint surface 11 are in abutment with each other;

[0128] After splicing, the left side plate 92 is fixed to the bottom plate with bolts;

[0129] Similarly, the splicing of the cabinet front panel and the right panel, the splicing of the cabinet rear panel and the left panel, and the splicing of the cabinet rear panel and the right panel can refer to the splicing example of the cabinet front panel 91 and the left panel 92;

[0130] After the front plate 91, the left side plate 92, the rear plate, and the right side plate are fixed to the bottom plate, the top plate is finally installed to complete the installation of the entire cabinet.

[0131] This spliced ​​cabinet can transport the cabinet to the installation point in a disassembled structure and then splice it, without the need to transport the entire cabinet. It is especially suitable for installation environments such as mountainous areas where it is difficult to transport the entire cabinet.

[0132] The protective body of the cabinet is still composed of the bottom plate, the top plate, the front plate 91, the left side plate 92, the rear plate and the right side plate. Therefore, the cabinet assembled on site does not change the protective performance of the cabinet;

[0133] In order to facilitate the splicing of adjacent door panels and avoid mutual interference during splicing, the waterproof structure after splicing has a first gap 51, a second gap 41 and a top gap. Water entering from the top gap and the first gap 51 will not flow out from the second gap, but will only be discharged from the cabinet through the drainage channel 3 through the drainage groove. The waterproof level reaches IPX5 waterproof level.

[0134] The spliced ​​cabinet is not limited to communication energy cabinets, nor is it limited to installation sites with inconvenient transportation. It can also be used in conventional cabinets and conventional installation sites.

[0135] Example 10. Figure 1-3 as well as Figure 8 A communication base station cabinet is also shown, comprising a bottom plate and a top plate, wherein the bottom plate is provided with adjacent door panels: a front plate 91, a left side plate 92, a rear plate, and a right side plate; the adjacent door panels are spliced ​​by the cabinet door panel splicing waterproof structure and then fixed by bolts, and the first splicing surface 1 has a side extension surface 16;

[0136] The communication base station cabinet is used to set up at least any one of the following communication equipment: 4G base station, 5G base station, 6G base station, base station energy equipment, and network communication equipment.

[0137] The first splicing surface 1 is bent at multiple right angles from the side extension surface 16 to form the first splicing surface 1 that can be spliced ​​with the second splicing surface 2 .

[0138] For cabinet splicing, please refer to Example 9.

[0139] This communication base station cabinet can be transported to the installation point in a disassembled structure and then assembled, without the need to transport the entire cabinet. It is especially suitable for installation environments such as mountainous areas where it is difficult to transport the entire cabinet.

[0140] The protective body of the communication base station cabinet is still composed of the bottom plate, the top plate, the front plate 91, the left side plate 92, the rear plate and the right side plate. Therefore, the cabinet assembled on site does not change the protection performance of the cabinet to reach the protection level of IP55;

[0141] In order to facilitate the splicing of adjacent door panels and avoid mutual interference during splicing, the waterproof structure after splicing has a first gap 51, a second gap 41 and a top gap. Water entering from the top gap and the first gap 51 will not flow out from the second gap, but will only be discharged from the cabinet through the drainage channel 3 through the drainage groove. The waterproof level reaches IPX5 waterproof level.

[0142] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
