For example, including at least one means including one, two or more, and there is no limit on which ones are included. For example, including at least one of A, B and C, then A, B, C, A and B, A and C, B and C, or A, B and C can be included.

[0061] LED display screens and the like are commonly used outdoor display devices, which are usually provided with a power supply box to provide electrical energy for themselves.

[0062] In the related art, the power box generates a lot of heat when working, which leads to a large temperature difference between the inside and outside of the power box, and finally leads to a large pressure difference between the inside and outside of the power box. For this reason, the power box is also provided with a breathable valve to balance the air pressure inside and outside the power box. However, the pressure difference between the inside and outside of the power box can easily cause the liquid around the breathable valve to penetrate into the inside of the power box, thereby causing damage to the components inside the power box.

[0063] Based on this, in the embodiment of the present application, a waterproof component is provided at one end of the air-permeable valve located outside the power box to separate at least a portion of the air-permeable valve located outside the power box from the external environment, thereby preventing liquid from the external environment from directly flowing to the air-permeable valve, thereby improving the technical problem that liquid easily penetrates into the power box from the air-permeable valve. A more detailed example will be given below.

[0064] The embodiment of the present application provides a power supply box, which can be used in display devices such as LED display screens, and can also be other outdoor devices, household devices, etc., which are not limited in the embodiment of the present application.

[0065] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of a power box provided in an embodiment of the present application. The power box includes a housing 100, a vent valve 200 and a waterproof component 300. The vent valve 200 is provided through the housing 100, and the vent valve 200 includes a vent end 21 located outside the housing 100. Therefore, when there is an air pressure difference between the inside and outside of the power box, the inside of the power box can be ventilated through the vent end 21 to balance the air pressure inside and outside the power box. The waterproof component 300 is mounted on the housing 100, and the waterproof component 300 is covered on the vent end 21 to separate at least a part of the vent end 21 from the external environment. Then, when the liquid in the external environment flows to the vent end 21 under the action of air pressure, it will be blocked by the waterproof component 300 and it is difficult to flow directly to the vent end 21, thereby improving the technical problem that the liquid easily penetrates into the power box from the vent end 21.

[0066] Next, the technical solution of the embodiment of the present application is first illustrated with reference to the installation method of the waterproof component 300 .

[0067] Please continue to refer to Figure 2 , Figure 2 for Figure 1 The power box may further include a button 400 , which is disposed on the housing 100 , and the waterproof component 300 is sleeved on the button 400 to be snap-connected to the button 400 .

[0068] It is understandable that the housing 100 of the power box is usually provided with function buttons 400 such as a test button, a switch button, etc. Then, the embodiment of the present application reuses the buttons 400 provided on the housing 100 for fixing the waterproof component 300, which can reduce the number of holes opened on the housing 100 for installing the waterproof component 300, thereby not only reducing the cost and manufacturing difficulty of opening holes in the housing 100, but also avoiding the housing 100 from easily getting water inside the power box due to too many holes, and reducing the strength of the housing 100.

[0069] For example, please continue to refer to Figure 3 , Figure 3 for Figure 2 The cross-sectional view of the power box along the AA direction is shown. The waterproof component 300 includes an extension portion 31. The extension portion 31 is sleeved on the button 400 to be fixed to the button 400 by snapping.

[0070] Please combine Figure 3 and Figure 4 , Figure 4 for Figure 3 A schematic diagram of the structure of the waterproof component of the power box shown. In some embodiments, the extension portion 31 is a deformable material; for example, the extension portion 31 is made of rubber or silicone material, which is not limited in the embodiments of the present application. The extension portion 31 is provided with a first sealing rib 311. The first sealing rib 311 is arranged around the button 400 and abuts against the outer surface of the housing 100.

[0071] Then, taking the case where the housing 100 is provided with a first through hole 11 and the button 400 is inserted through the first through hole 11 as an example, on the one hand, the extension part 31 is tightly fitted with the outer surface of the housing 100 through the first sealing rib 311, and the first sealing rib 311 can be fully fitted with the end surface of the hole opening of the first through hole 11; on the other hand, the extension part 31 is sleeved on the button 400 to tightly fit with the peripheral surface of the button 400. Therefore, the extension part 31 is used not only for installing the waterproof component 300, but also for sealing between the button 400 and the hole wall of the first through hole 11, so as to prevent the liquid outside the power box from penetrating into the power box from the first through hole 11, and finally improve the safety of the power box.

[0072] It should be noted here that the extension part 31 is made of a deformable material, and the entire waterproof component 300 may be made of a deformable material, such as the waterproof component 300 may be an injection-molded silicone component, a rubber component, etc. Optionally, only the extension part 31 of the waterproof component 300 may be made of a deformable material, and the embodiment of the present application is not limited to this.

[0073] In some embodiments, a flange 41 is provided on the outer peripheral side of one end of the button 400 located outside the housing 100, and at least part of the extension portion 31 is located between the flange 41 and the outer surface of the housing 100. Therefore, when the user presses the button 400, even if the button 400 moves toward the inside of the housing 100, the flange 41 can abut against the side surface of the extension portion 31 away from the housing 100 to limit the extension portion 31 from separating from the button 400, thereby improving the stability and reliability of the installation of the waterproof component 300.

[0074] Please refer to Figure 3 and Figure 5 , Figure 5 for Figure 3 A schematic diagram of the structure of the waterproof component of the power box from another perspective. In some embodiments, the extension portion 31 is provided with a first waterproof rib 312. The first waterproof rib 312 is located on the side of the extension portion 31 away from the housing 100 and is arranged around the button 400. Thus, the first waterproof rib 312 can prevent liquid from directly flowing to the peripheral surface of the button 400, so as to reduce the probability of liquid penetrating into the interior of the power box from the first through hole 11.

[0075] In some embodiments, Figure 2 As shown, the housing 100 is provided with a heat dissipation structure 12, so that the heat dissipation structure 12 can achieve a good heat dissipation effect on the power box. Then, it can also be understood that, since the heat dissipation structure 12 can reduce the temperature inside the power box, the corresponding air pressure difference between the inside and outside of the power box will be reduced, so the liquid outside the housing 100 is not easily pressed into the power box by the air pressure difference.

[0076] In some embodiments, the waterproof component 300 is snap-fitted with the heat dissipation structure 12. Then, in the embodiment of the present application, the heat dissipation structure 12 provided on the housing 100 is reused to fix the waterproof component 300, so that the number of holes provided on the housing 100 for installing the waterproof component 300 can be reduced, thereby not only reducing the cost and manufacturing difficulty of providing holes in the housing 100, but also preventing the housing 100 from easily getting water inside the power box and reducing the strength of the housing 100 due to too many holes.

[0077] The heat dissipation structure 12 may include at least one of a heat dissipation fin and a heat dissipation rib 121, so that the contact area between the housing 100 and the air can be increased through the heat dissipation fin and the heat dissipation rib 121, thereby improving the heat dissipation efficiency and improving the strength of the housing 100. Of course, the heat dissipation structure 12 may also include any other structure for heat dissipation, which is not limited in the embodiment of the present application.

[0078] In some embodiments, the heat dissipation rib 121 may be extended along the length direction of the housing 100. For example, the heat dissipation rib 121 extends from one end to the other end of the housing 100 in the length direction, so that the heat dissipation rib 121 is longer as a whole, thereby increasing the heat dissipation efficiency of the power box by increasing the contact area between the housing 100 and the air.

[0079] The following is an example of the installation method of the waterproof component 300 by taking the heat dissipation structure 12 including the heat dissipation ribs 121 as an example.

[0080] The heat dissipation structure 12 may include at least two heat dissipation ribs 121 disposed at intervals. The waterproof component 300 is clamped between two adjacent heat dissipation ribs 121 .

[0081] It can be understood that the waterproof component 300 can be clamped between two adjacent heat dissipation ribs 121 but not clamped to the button 400; the waterproof component 300 can also be clamped to the button 400 but not clamped between two adjacent heat dissipation ribs 121; the waterproof component 300 can also be clamped between two adjacent heat dissipation ribs 121 and clamped to the button 400, and the embodiments of the present application are not limited to this.

[0082] Then, when the waterproof component 300 is clamped between two adjacent heat dissipation ribs 121 and also clamped to the button 400, the waterproof component 300 is clamped by the two adjacent heat dissipation ribs 121, which can effectively prevent the waterproof component 300 from circumferentially rotating around the button 400, thereby improving the stability and reliability of the installation of the waterproof component 300.

[0083] Exemplarily, the heat dissipation structure 12 may include at least two groups of heat dissipation ribs 121, wherein the first group of heat dissipation ribs 121 is disposed on one side (such as the left side) of the vent valve 200, and the second group of heat dissipation ribs 121 is disposed on the other side (such as the right side) of the vent valve 200 away from the first group of heat dissipation ribs 121. At this time, an installation space is formed between the first group of heat dissipation ribs 121 and the second group of heat dissipation ribs 121, and the button 400 and the vent valve 200 are both disposed in the installation space. Correspondingly, the waterproof component 300 is also disposed in the installation space, and the end surface of one side of the waterproof component 300 close to the first group of heat dissipation ribs 121 abuts against one heat dissipation rib 121 in the first group of heat dissipation ribs 121, and the end surface of one side of the waterproof component 300 close to the second group of heat dissipation ribs 121 abuts against one heat dissipation rib 121 in the second group of heat dissipation ribs 121, so that the waterproof component 300 can be sleeved on the button 400 through the extension portion 31, and can be clamped between two adjacent heat dissipation ribs 121.

[0084] Please continue to refer to Figure 6 and Figure 7 , Figure 6 for Figure 1The schematic diagram of the structure of the power box shown is equipped with the second waterproof component. Figure 7 for Figure 6 The cross-sectional view of the power box along the BB direction is shown. In some embodiments, the heat dissipation structure 12 includes a heat dissipation rib 121. The waterproof component 300 is provided with a card slot 32, and the heat dissipation rib 121 is partially carded in the card slot 32.

[0085] It is understandable that only a portion of the heat dissipation rib 121 can be connected to the card slot 32, which can realize the installation of the waterproof component 300 and avoid the waterproof component 300 covering too much of the heat dissipation rib 121, thereby reducing the heat dissipation effect of the heat dissipation rib 121.

[0086] In addition, it can also be understood that, since the waterproof component 300 does not need to be clamped between two adjacent heat dissipation ribs 121, the number of heat dissipation ribs 121 can also be one, and the embodiment of the present application does not limit this.

[0087] That is to say, the number of the card slot 32 and the number of the heat dissipation rib 121 can both be one. The number of the card slot 32 can also be two, and correspondingly, the number of the heat dissipation rib 121 is at least two, and each card slot 32 is connected to a different heat dissipation rib 121, which is not limited in the embodiment of the present application.

[0088] It should also be noted that the waterproof component 300 can be engaged with the heat dissipation rib 121 through the slot 32 but not engaged with the button 400; the waterproof component 300 can also be engaged with the button 400 but not engaged with the heat dissipation rib 121 through the slot 32; the waterproof component 300 can also be engaged with the heat dissipation rib 121 through the slot 32 and engaged with the button 400, and the embodiments of the present application are not limited to this.

[0089] Exemplarily, the heat dissipation structure 12 may include at least two groups of heat dissipation ribs 121, wherein the first group of heat dissipation ribs 121 is disposed on one side (such as the left side) of the vent valve 200, and the second group of heat dissipation ribs 121 is disposed on the side (such as the right side) of the vent valve 200 away from the first group of heat dissipation ribs 121. At this time, the first group of heat dissipation ribs 121 and the second group of heat dissipation ribs 121 form an installation space, and the button 400 and the vent valve 200 are both disposed in the installation space. A first card slot 32 is provided on the side of the waterproof component 300 close to the first group of heat dissipation ribs 121, and the heat dissipation ribs 121 of the first group of heat dissipation ribs 121 are clamped in the first card slot 32; a second card slot 32 is provided on the side of the waterproof component 300 close to the second group of heat dissipation ribs 121, and the heat dissipation ribs 121 of the second group of heat dissipation ribs 121 are clamped in the second card slot 32, so that the waterproof component 300 can be sleeved on the button 400 through the extension portion 31, and can also be clamped between two adjacent heat dissipation ribs 121.

[0090] In some embodiments, the waterproof component 300 may also be fixed to the breathable valve 200 .

[0091] It should be noted at this point that the waterproof component 300 can be fixed to only one of the button 400, the heat dissipation structure 12 and the breathable valve 200, or the waterproof component 300 can be fixed to only any two of the button 400, the heat dissipation structure 12 and the breathable valve 200, or the waterproof component 300 can be fixed to the button 400, the heat dissipation structure 12 and the breathable valve 200 at the same time, so as to further improve the stability and reliability of the installation of the waterproof component 300, and the embodiments of the present application are not limited to this.

[0092] Next, the technical solution of the embodiment of the present application will be described with examples in combination with the structure in which the waterproof component 300 is fixed to the breathable valve 200.

[0093] Please continue to refer to Figure 8 , Figure 8 for Figure 6 A schematic diagram of the structure of the power box from another perspective is shown. The waterproof component 300 may include a mounting body 33 and a flap 34. The mounting body 33 is sleeved on the vent end 21, so that the waterproof component 300 is fixed to the vent valve 200. The flap 34 is a deformable material; for example, the flap 34 is made of rubber or silicone. One end of the flap 34 is connected to the mounting body 33, and the other part of the flap 34 is separated from the mounting body 33 and forms a deformation part 341, which is covered on the vent end 21 so that the deformation part 341 can be bent in a direction away from the mounting body 33 to expose the vent valve 200.

[0094] Therefore, during the operation of the power box, the flap 34 can be placed on the vent end 21 to prevent liquid from directly flowing into the vent end 21. When the vent valve 200 needs to be disassembled and maintained, the deformed portion 341 of the flap 34 can be bent to expose the vent end 21, thereby facilitating the vent valve 200 to be disassembled and maintained.

[0095] It should be noted here that the flip cover 34 is made of a deformable material, and the entire waterproof component 300 may be made of a deformable material, such as an injection-molded silicone component, a rubber component, etc. Optionally, only the flip cover 34 of the waterproof component 300 may be made of a deformable material, which is not limited in the embodiment of the present application.

[0096] As mentioned above, the waterproof component 300 may further include an extension portion 31 to be sleeved on the button 400. Then, the extension portion 31 may be formed by the installation body 33 extending toward one side of the button 400.

[0097] As mentioned above, the waterproof component 300 may also be clamped between two adjacent heat dissipation ribs 121 . Then, at least one of the extension portion 31 and the mounting body 33 may be clamped between two adjacent heat dissipation ribs 121 .

[0098] As mentioned above, the waterproof component 300 may also be provided with a slot 32 for engaging with the heat dissipation rib 121. Then, the slot 32 may be formed only in one of the extension portion 31 and the installation body 33, and the slot 32 may also extend from the installation body 33 to the extension portion 31, thereby increasing the engagement area between the waterproof component 300 and the heat dissipation rib 121 to improve the stability and reliability of the installation of the waterproof component 300.

[0099] Please continue to refer to Fig. 9 , Fig. 9 for Figure 6 A schematic diagram of the structure of the second waterproof component is shown. In some embodiments, the flap 34 is spaced apart from the vent valve 200. An air hole 35 is formed between the mounting body 33 and the deformed portion 341. The air hole 35 faces the peripheral surface of the vent end 21. Furthermore, the inside and outside of the waterproof component 300 can be connected through the air hole 35, so that the air valve 200, the gap between the air valve 200 and the flap 34, and the air hole 35 can form a gas flow path for air flow inside and outside the power box to balance the air pressure inside and outside the power box.

[0100] Exemplarily, the mounting body 33 may include a bottom wall 331 and a side wall 332. The bottom wall 331 is sleeved on the ventilating end 21. The side wall 332 is arranged on a side of the bottom wall 331 close to the flip cover 34. The side wall 332 includes a first side wall 3321, a second side wall 3322, and a third side wall 3323 connected in sequence. The first side wall 3321, the second side wall 3322, and the third side wall 3323 are respectively located on different sides of the ventilating end 21 in the circumferential direction. The second side wall 3322 is connected to the flip cover 34. A vent hole 35 is formed between an end of the first side wall 3321 away from the second side wall 3322, an end of the third side wall 3323 away from the second side wall 3322, the bottom wall 331, and the flip cover 34 (such as the deformed portion 341 of the flip cover 34).

[0101] For example, the first side wall 3321 may be located on the left side of the ventilating end 21, the third side wall 3323 may be located on the right side of the ventilating end 21, the corresponding second side wall 3322 may be located on the upper side of the ventilating end 21, and the vent hole 35 may be formed on the lower side of the ventilating end 21. Thus, it is possible to prevent the liquid flowing downward from the top of the waterproof component 300 from flowing into the inner side of the flip cover 34 through the vent hole 35.

[0102] Of course, when the user needs to bend the deformed portion 341 of the flip cover 34 , the deformed portion 341 can be lifted up from the vent hole 35 more conveniently, so that the user can disassemble and maintain the vent valve 200 .

[0103] In some embodiments, the second side wall 3322 may be an arc-shaped structure convex in a direction away from the vent hole 35. Thus, the liquid flowing downward from the top of the waterproof component 300 may flow downward along the second side wall 3322 more smoothly, thereby preventing water from accumulating on the upper surface of the second side wall 3322.

[0104] In some embodiments, the first side wall 3321 and the second side wall 3322 are separated from the deformation portion 341. Exemplarily, a spacing groove 36 is formed between the flip cover 34 and the first side wall 3321 and the second side wall 3322, so as to facilitate the flip cover 34 to bend away from the installation body 33.

[0105] Please combine Figure 7 and Fig.10 , Fig.10 for Figure 6 The schematic diagram of the structure of the second waterproof component from another perspective is shown. In some embodiments, the bottom wall 331 is a deformable material; for example, the bottom wall 331 is made of rubber or silicone. The bottom wall 331 is provided with a second sealing rib 3311, which is arranged around the ventilating end 21 and abuts against the outer surface of the housing 100.

[0106] Then, taking the second through hole 13 provided in the housing 100 and the vent valve 200 passing through the second through hole 13 as an example, the second sealing rib 3311 is provided around the vent end 21 and abuts against the outer surface of the housing 100, and the second sealing rib 3311 can be in full contact with the end surface of the opening of the second through hole 13. Therefore, the bottom wall 331, in addition to being used to install the waterproof component 300, can also achieve sealing at the second through hole 13 through the second sealing rib 3311 to prevent liquid outside the power box from penetrating into the power box from the second through hole 13, thereby improving the safety of the power box.

[0107] It should be noted that the bottom wall 331 is a deformable material, and the entire waterproof component 300 may be a deformable material, such as the waterproof component 300 may be an injection-molded silicone component, a rubber component, etc. Optionally, only the bottom wall 331 and the flip cover 34 of the waterproof component 300 may be a deformable material, and the embodiment of the present application is not limited to this.

[0108] Please combine Figure 7 and Fig. 9In some embodiments, the bottom wall 331 is provided with a second waterproof rib 3312, which is located on the side of the bottom wall 331 facing the flip cover 34 and is arranged around the ventilating end 21. Thus, the second waterproof rib 3312 can prevent liquid from directly flowing to the peripheral surface of the ventilating end 21, so as to reduce the probability of liquid penetrating into the power box from the second through hole 13.

[0109] The second waterproof rib 3312 may be located on the inner side of the side wall 332 or on the outer side of the side wall 332 , which is not limited in the embodiment of the present application.

[0110] The embodiment of the present application also provides an LED display screen, which may include the above-mentioned power box.

[0111] Please continue to refer to Fig.11 , Fig.11 A schematic diagram of the structure of an LED box provided in an embodiment of the present application. The LED display screen is composed of a plurality of LED boxes. The LED box includes a frame 500, at least one LED light board module 600 and a power supply box. The LED light board module 600 is mounted on the frame 500. The power supply box (such as a housing 100 of the power supply box) is mounted on the frame 500, and the power supply box is electrically connected to the LED light board module 600.

[0112] Thus, the LED light board module 600 can be powered by the power box, and then a plurality of LED boxes can be spliced ​​or stacked through their respective frames 500 to form an LED display screen.

[0113] In some embodiments, the frame 500 may be provided with a plurality of mounting positions 51, each mounting position 51 being provided with an LED light board module 600. Of course, each LED box may also be provided with only one LED light board module 600, which is not limited in the embodiment of the present application.

[0114] In some embodiments, the power box may be installed on a side of the frame 500 facing away from the LED light board module 600 .
