Abstract
Description
Technical Field
[0001] The utility model relates to the field of display technology, and more specifically, to a power supply box of a display device and also to a display device comprising the power supply box of the display device. Background Art
[0002] The waterproof structure of traditional LED display screen has the following two problems when in use:
[0003] (1) It is difficult to flatten. That is, when the LED display is installed in a box with a waterproof structure, there will be a height difference between the position where the waterproof ring is set and other planes, which will lead to a low flatness of the LED display, thus affecting the display effect of the LED display;
[0004] (2) The waterproof level is relatively low. That is, the waterproof structure of traditional LED display screens usually directly presses the waterproof ring onto the parts to be assembled, and achieves waterproofing through the compression of the waterproof ring. When the compression of the waterproof ring is large, the resilience of the waterproof ring is also relatively large. Therefore, the position where the waterproof ring is pressed must be a position with sufficient strength. Otherwise, the compression of the waterproof ring will be insufficient or the parts to be assembled will be deformed, resulting in low waterproof performance of the device.
[0005] In summary, how to improve the waterproof effect and assembly flatness of LED display screens is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content
[0006] In view of this, the purpose of the utility model is to provide a power supply box for a display device, which can improve the waterproof effect and assembly flatness of an LED display screen.
[0007] Another object of the utility model is to provide a display device comprising a power supply box of the display device.
[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0009] A power supply box for a display device, comprising:
[0010] A shell body, in which a cavity is provided, and an opening side of the shell body is provided with a sealing groove along the circumferential direction;
[0011] A sealing member, which is arranged in the sealing groove, and the sealing member comprises multiple layers of waterproof rings distributed in a stepped manner;
[0012] The cover plate is arranged on the opening side, the sealing member is sandwiched between the cover plate and the shell, and the side of the sealing member which is distributed in a stepped manner is in contact with the cover plate.
[0013] In one embodiment, the sealing element comprises three layers of waterproof rings, and each layer of the waterproof rings is spaced apart.
[0014] In one embodiment, the height of the waterproof ring close to the cavity is greater than the height of the waterproof ring in the middle, and the height of the waterproof ring in the middle is greater than the height of the waterproof ring far from the cavity.
[0015] In one embodiment, the three layers of waterproof ring are an integrated structure.
[0016] In one embodiment, the outermost circle of the shell is provided with an external water retaining brim, and the sealing groove is located at the inner circumference of the external water retaining brim.
[0017] In one embodiment, the innermost circle of the shell is provided with an internal water retaining brim, and the sealing groove is located at the outer periphery of the internal water retaining brim.
[0018] In one embodiment, the height of the external water retaining brim is greater than the height of the internal water retaining brim, and the height of the internal water retaining brim is greater than the maximum height of the sealing element.
[0019] In one embodiment, a water leakage groove distributed around the edge of the shell is provided between the external water retaining brim and the sealing groove, a drainage port is provided at the bottom of the external water retaining brim, and the water leakage groove is connected to the drainage port.
[0020] In one embodiment, the cover plate is provided with a plurality of first mounting frames spaced apart along the circumferential direction, the shell is provided with a plurality of second mounting frames distributed corresponding to the first mounting frames, and both the first mounting frames and the second mounting frames are provided with mounting holes for installing fasteners.
[0021] A display device comprises: a power supply box of any one of the display devices described above.
[0022] When using the power supply box of the display device provided by the utility model, first, the sealing member can be placed in the sealing groove of the shell, and then the cover plate and the opening side of the shell are closed and connected. In the process of pressing the cover plate, the highest waterproof ring contacts the cover plate first, and the waterproof ring is compressed and deformed under the pressing action of the cover plate, so that the waterproof ring and the cover plate are sealed and connected. As the pressing force increases, the waterproof ring with the second highest height contacts the cover plate, and the waterproof ring is also compressed and deformed under the pressing action of the cover plate, so that the waterproof ring and the cover plate are sealed and connected.
[0023] That is, the multiple layers of waterproof rings distributed in a stepped manner can contact the cover plate in turn, and be compressed and deformed in turn under the pressing action of the cover plate, which can make the resistance of the compression seal of the cover plate smaller than the resistance of directly contacting the multiple layers of waterproof rings. Since the multiple layers of waterproof rings contact the cover plate in turn, the compression deformation of each waterproof ring increases slowly in turn, and this design can make the cover plate easier to flatten. Moreover, the multiple layers of waterproof rings with different compression deformation amounts can make the force on the cover plate relatively small when it is compressed, avoiding the deformation of the pressure plate, which further affects the waterproof sealing effect of the waterproof ring. In addition, the structure of the device is simple and easy to manufacture, and it can be promoted and used.
[0024] In summary, the power supply box of the display device provided by the utility model can improve the waterproof effect and assembly flatness of the LED display screen.
[0025] In addition, the utility model also provides a display device including a power box of the above-mentioned display device. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The core of the utility model is to provide a power supply box of a display device, which can improve the waterproof effect and assembly flatness of an LED display screen. Another core of the utility model is to provide a display device including the power supply box of the display device.
[0037] Please refer to Figures 1 to 6 , Figure 1 An exploded view of a power supply box of a display device provided by the utility model; Figure 2 It is a schematic diagram of the assembly of the housing and the seal; Figure 3 for Figure 2 A partial enlarged view of the lower part; Figure 4 for Figure 2 The main view; Figure 5 for Figure 4 AA section view; Figure 6 for Figure 5 A partial enlargement of the upper part.
[0038] This specific embodiment provides a power supply box of a display device, comprising:
[0039] A housing 1 is provided with a cavity 11 therein, and a sealing groove 12 is provided along the circumferential direction on the opening side of the housing 1;
[0040] The sealing member 2 is arranged in the sealing groove 12, and the sealing member 2 includes multiple layers of waterproof rings 21 distributed in a stepped manner;
[0041] The cover plate 3 is arranged on the opening side, and the sealing member 2 is sandwiched between the cover plate 3 and the housing 1 . The side of the sealing member 2 which is distributed in a stepped manner is in contact with the cover plate 3 .
[0042] It should be noted that an LED light board can be provided on the closed side of the shell 1, and during actual use, the shape, structure, size, material, etc. of the shell 1, the seal 2 and the cover 3 can be determined according to actual conditions and actual needs.
[0043] When using the power supply box of the display device provided by the utility model, first, the sealing member 2 can be placed in the sealing groove 12 of the housing 1, and then the cover plate 3 and the opening side of the housing 1 are covered and connected. In the process of pressing the cover plate 3, the highest waterproof ring 21 first contacts the cover plate 3, and the waterproof ring 21 is compressed and deformed under the pressing action of the cover plate 3, so that the waterproof ring 21 and the cover plate 3 are sealed and connected. As the pressing force increases, the waterproof ring 21 with the second highest height contacts the cover plate 3, and the waterproof ring 21 is also compressed and deformed under the pressing action of the cover plate 3, so that the waterproof ring 21 and the cover plate 3 are sealed and connected.
[0044] That is, the multiple layers of waterproof rings 21 distributed in a stepped manner can contact the cover plate 3 in turn, and be compressed and deformed in turn under the pressing action of the cover plate 3, so that the resistance of the pressing seal 2 of the cover plate 3 is relatively smaller than the resistance of directly contacting the multiple layers of waterproof rings 21 or the entire waterproof ring 21 of a large area. Since the multiple layers of waterproof rings 21 contact the cover plate 3 in turn, the compression deformation of each waterproof ring 21 increases slowly in turn, and this design can make the cover plate 3 easier to flatten. Moreover, the multiple layers of waterproof rings 21 with different compression deformation amounts can make the force on the cover plate 3 relatively small when it is pressed (the force on directly and simultaneously pressing the multiple layers of waterproof rings 21), avoiding the deformation of the pressure plate, which further affects the waterproof sealing effect of the waterproof ring 21. In addition, the structure of the device is simple, the manufacturing is convenient, and it can be promoted and used.
[0045] In summary, the power supply box of the display device provided by the utility model can improve the waterproof effect and assembly flatness of the LED display screen.
[0046] In one embodiment, the sealing member 2 includes a three-layer waterproof ring 21, the structure of which is as follows: Figure 6 As shown, each layer of waterproof ring 21 is spaced apart. Among them, each layer of waterproof ring 21 is spaced apart so that each layer of waterproof ring 21 can be compressed and deformed under the extrusion of the cover plate 3, and the space between each waterproof ring 21 can form an annular groove, which can also be used to accommodate water flow to prevent water flow from passing over each waterproof ring 21 and entering the cavity 11. Of course, in other embodiments, the sealing member 2 can also include other layers of waterproof rings 21, such as two layers, four layers, five layers, etc., without specific limitation.
[0047] In one embodiment, the height of the waterproof ring 21 close to the cavity 11 is greater than the height of the waterproof ring 21 in the middle, and the height of the waterproof ring 21 in the middle is greater than the height of the waterproof ring 21 far from the cavity 11. Figure 6 The heights mentioned in this application refer to the Figure 6 The lateral extension distance in the cross section shown is that the greater the height of the structure, the greater the lateral extension distance.
[0048] It should be noted that a drain groove 15 for drainage can be provided between the sealing groove 12 and the outermost circle of the housing 1. When the water potential is so great that the drain groove 15 cannot drain the water in time, the water will be blocked by the multiple layers of stepped waterproof rings 21. When the cover plate 3 is pressed against the housing 1, the housing 1 will first contact the waterproof ring 21 closest to the cavity 11, then the middle waterproof ring 21, and finally the waterproof ring 21 far from the cavity 11.
[0049] If the seal 2 only includes one layer of seal 2 with a large compression amount (equivalent to the sum of the compression amounts of the three waterproof rings 21), when the cover plate 3 presses the seal 2, it will directly press the entire plane of the seal 2, the compression resistance is large, and the rebound force is also large. A large force is required to make the cover plate 3 press the seal 2, which is easy to cause the cover plate 3 to deform, and the sealing effect of only one layer of waterproof ring 21 is general. In the present application, three layers of waterproof rings 21 with stepped distribution are used, which can make the resistance encountered by the cover plate 3 in the process of pressing the seal 2 smaller, and make the rebound force of the waterproof ring 21 relatively small, avoiding deformation of the cover plate 3, and multiple layers of waterproof rings 21 are conducive to improving the sealing effect of the device.
[0050] In addition, the gaps between the waterproof rings 21 can accommodate water, which helps to prevent water from directly passing over the seal 2 and entering the cavity 11. Therefore, the seal 2 of the present application can prevent the LED display from having a significant height difference while fully ensuring the compression amount, thereby improving the waterproof sealing effect of the LED display.
[0051] It should be noted that the compression amounts of the three layers of waterproof rings 21 with different heights and stepped distribution are not the same. For example, the compression amount of the first layer of waterproof ring 21 can be set to 1.0 mm, the compression amount of the second layer of waterproof ring 21 can be set to 1.3 mm, and the compression amount of the third layer of waterproof ring 21 can be set to 1.5 mm. By setting three layers of waterproof rings 21 with different heights and different compression amounts, the force on the cover plate 3 will not be too large when the cover plate 3 is pressed against the sealing member 2, so as to avoid deformation of the cover plate 3 due to excessive force and affect the waterproof effect. Moreover, the compression amount of each layer of waterproof ring 21 increases slowly, which can make the cover plate 3 easier to flatten and ensure the sealing connection effect between the cover plate 3 and the sealing member 2.
[0052] In one embodiment, the three-layer waterproof ring 21 is an integrated structure to simplify the assembly process of the device, without the need to sequentially install each layer of the waterproof ring 21 in the sealing groove 12 .
[0053] In one embodiment, the outermost ring of the housing 1 is provided with an external water retaining brim 13, and the sealing groove 12 is located at the inner periphery of the external water retaining brim 13. Figure 3 , 56. The external water retaining brim 13 is similar to a house tile and has a drainage function, which can prevent a part of water from entering the cavity 11 of the housing 1.
[0054] In one embodiment, the innermost circle of the housing 1 is provided with an internal water retaining brim 14, and the sealing groove 12 is located at the outer periphery of the internal water retaining brim 14. Figure 3 , 5 6. The internal water retaining brim 14 is similar to a house tile and has a drainage function, which can prevent a portion of water from entering the cavity 11 of the housing 1. That is, the structure of the external water retaining brim 13 and the internal water retaining brim 14 is similar to improve the sealing and waterproof effect of the device.
[0055] In one embodiment, the height of the outer water retaining brim 13 is greater than the height of the inner water retaining brim 14, and the height of the inner water retaining brim 14 is greater than the maximum height of the sealing member 2. Figure 6 shown.
[0056] It should be noted that outdoor LED display screens are usually installed vertically. Various connectors and electrical components can be placed in the cavity 11 of the housing 1. In order to prevent water from entering the cavity 11 and damaging the device, the device can be provided with an external water retaining brim 13, a water leakage groove 15, a sealing member 2 and an external water retaining brim 13 in sequence. Figure 6 As shown. The water flow can first be blocked by the external water-retaining brim 13. When part of the water flow passes over the external water-retaining brim 13 and enters the water leakage groove 15, the water flow can be discharged outward through the water leakage groove 15. When part of the water flow passes over the water leakage groove 15 and enters the seal 2, the multi-layer stepped seal 2 and the cover plate 3 will be compressed and deformed after being pressed tightly, and the multi-layer sealing ring can effectively seal the cover plate 3 to prevent the water flow from entering the cavity 11. If part of the water flow passes over the seal 2, it can also be blocked by the internal water-retaining brim 14 to further prevent the water flow from entering the cavity 11. That is, the device is provided with a variety of waterproof and drainage methods, which effectively improves the sealing and waterproof effect of the device.
[0057] In one embodiment, the cover plate 3 is provided with a plurality of first mounting frames 31 spaced apart along the circumferential direction, the housing 1 is provided with a plurality of second mounting frames 17 distributed corresponding to the first mounting frames 31, and both the first mounting frames 31 and the second mounting frames 17 are provided with mounting holes for mounting fasteners, and the structure is as follows: Figure 1 As shown. That is, after the cover plate 3 is pressed against the sealing ring, the fasteners can be inserted into the mounting holes of the first mounting frame 31 and the second mounting frame 17 in sequence, and the fasteners (such as bolts) can be tightened to ensure that the connection between the cover plate 3 and the housing 1 is in place. Moreover, the cover plate 3 is provided with a plurality of first mounting frames 31 along the circumference, which can make the cover plate 3 more evenly stressed, and is conducive to reducing the risk of deformation of the cover plate 3 due to uneven stress.
[0058] In one embodiment, a water leakage groove 15 is provided between the external water retaining cap brim 13 and the sealing groove 12, and the water leakage groove 15 is distributed around the edge of the shell 1. The bottom of the external water retaining cap brim 13 is provided with a drain port 16, and the water leakage groove 15 is connected to the drain port 16. Figure 3 That is, when the water potential is too large and the water passes over the external water retaining brim 13 and enters the interior of the housing 1, the water will flow downward through the water leakage groove 15, and the water can flow to the drain port 16, and finally be discharged outward through the drain port 16 at the bottom of the external water retaining brim 13.
