Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a power supply box and a display device. Background Technology

[0002] Display devices are now widely used in the security industry, advertising and media industry, and most public places, with large-scale displays being particularly prevalent. Existing large-scale displays are heavy and often need to be fixed at heights, requiring maintenance personnel to perform high-altitude maintenance when they malfunction. Maintenance of the power supply box in large-scale displays often requires complete removal of the power supply box or opening the rear cover separately to repair the components inside. Because the power supply box of large-scale displays is also large and heavy, or cannot be fixed in place after the cover is opened, it is inconvenient for maintenance personnel to perform repairs, increasing the risks associated with high-altitude maintenance. Utility Model Content

[0003] The purpose of this invention is to improve the convenience of power box maintenance and reduce the risks of high-altitude maintenance.

[0004] To solve the above-mentioned technical problems, this utility model provides a power supply box, which is disposed on the mounting frame of a display device, characterized in that the power supply box includes:

[0005] The box body is configured to be mounted on the mounting frame. The box body has a first opening and a second opening on two opposite sides in the thickness direction. The first opening faces the front of the mounting frame, and the second opening faces away from the mounting frame.

[0006] A front cover, which is detachably mounted to the first opening of the housing, for closing the first opening;

[0007] A rear cover, which is rotatably disposed at the second opening of the box body, for opening or closing the second opening;

[0008] The connecting component includes a first connecting part and a second connecting part. The first connecting part is disposed on the box body, and the second connecting part is disposed on the rear cover. When the rear cover is rotated to one side of the box body, the first connecting part and the second connecting part are engaged, so that the rear cover can be positioned and fixed on the outside of the box body.

[0009] Optionally, the first connecting part is configured as a magnetic attractant, and the second connecting part is configured as another magnetic attractant that can be magnetically attracted to the first connecting part. When the back cover is flipped to one side of the box, the first connecting part and the second connecting part are magnetically connected, so that the back cover can be positioned and fixed to one side of the box.

[0010] Optionally, the power supply box further includes a rotating connector that rotatably connects the box body and the rear cover. The rotating connector includes a first connecting plate, a second connecting plate, and a rotating shaft for connecting the first connecting plate and the second connecting plate. The first connecting plate is located on one side of the box body, and the second connecting plate is located on one side of the rear cover. The second connecting plate can rotate around the axis of the rotating shaft, so that the rear cover can move relatively closer to or away from the second opening to open or close the second opening.

[0011] Optionally, the power supply box further includes a locking structure, which includes a first latching member and a second latching member. The first latching member is located at the bottom end of the rear cover and includes a latching portion and a pressing portion. The second latching member is located at the bottom end of the box body and has a limiting portion. The latching portion can latch onto the limiting portion to connect the first latching member and the second latching member. Pressing the pressing portion disengages the latching portion from the limiting portion, thereby disengaging the first latching member from the second latching member.

[0012] Optionally, multiple first fasteners are spaced apart at the bottom end of the rear cover, and multiple second fasteners are spaced apart at the bottom end of the box body, with one first fastener corresponding to one second fastener.

[0013] Optionally, the box body is provided with an electrical connection module, the inner side of the rear cover is provided with a heat-conducting component, the heat-conducting component is in contact with the electrical connection module, and the outer surface of the rear cover away from the heat-conducting component is provided with multiple heat dissipation teeth.

[0014] Optionally, the power supply box further includes a first sealing ring. The front cover has a first annular groove on its inner sidewall facing the box body. The first sealing ring is disposed in the first annular groove. When the front cover closes the first opening, the first sealing ring fits against the edge of the first opening.

[0015] Optionally, the power supply box further includes a second sealing ring. The rear cover has a second annular groove on its inner sidewall facing the box body. The second sealing ring is disposed in the second annular groove. When the front cover closes the second opening, the second sealing ring abuts against the edge of the second opening.

[0016] This application also proposes a display device, including a mounting frame and a plurality of display modules disposed on the mounting frame, and at least one power supply box as described in any of the preceding claims, wherein the plurality of display modules are arrayed on one side of the mounting frame to form a display surface, and the power supply box is disposed on the other side of the mounting frame.

[0017] Optionally, the power supply box integrates a high-voltage and low-voltage module, which is electrically connected to the display module and is responsible for providing a stable power supply and signal transmission for the display module.

[0018] As can be seen from the above technical solution, the beneficial effects of this utility model are as follows: The power supply box includes a box body, a front cover, a rear cover, and a connecting assembly located at the first opening. The box body has a first opening and a second opening, and the connecting assembly includes a first connecting part and a second connecting part. The rear cover is rotatably mounted at the second opening, allowing the rear cover to rotate relative to the box body to open or close the second opening. This allows the rear cover to be flipped to one side of the box body to expose the electrical connection module, facilitating maintenance personnel in repairs; without needing to disassemble the entire power supply box or the rear cover, reducing the number of parts that need to be removed and shortening the maintenance time for the power supply box. Furthermore, the first connecting part is connected to one side of the box body, and the second connecting part connects the rear cover to the same side of the box body. When the rear cover rotates to one side of the box body, the first connecting part connects with the second connecting part, allowing the rear cover to be positioned and fixed to one side of the box body. This prevents the rear cover from shaking or reclosing the second opening when flipped to one side of the box body, reducing the rear cover's interference with maintenance work and improving the convenience for maintenance personnel in repairing the power supply box.

[0030] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0031] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] Figure 1 A schematic diagram of a prior art power supply box fixed to a mounting frame is shown.

[0034] like Figure 1 As shown, in the prior art, the power supply box 100 is placed vertically within the mounting frame 200. When performing front maintenance on the power supply box 100, after removing the front maintenance screws, because the power supply box 100 is placed vertically within the mounting frame 200, the front cover of the power supply box 100 needs to be flipped towards the front of the mounting frame 200 (as shown in the right power supply box in the figure). Then, the power supply box 100 can be opened to maintain the components inside. Since the power supply box 100 of large display devices is also large in size and weight, it is inconvenient for maintenance personnel to perform repairs, increasing the risk of high-altitude maintenance.

[0035] Therefore, this application proposes a power supply box 100 that reduces the number of parts of the power supply box 100 that need to be removed during maintenance, improves the convenience of maintenance of the power supply box 100, and reduces the operational risks for maintenance personnel when performing maintenance on the power supply box 100 at heights.

[0036] Please see Figure 3 , Figure 4 and Figure 5 This application discloses a power supply box 100 disposed on the mounting frame 200 of a display device 1000 for electrical connection with a display module 300 of the display device 1000. The display module 300 is disposed on the front side of the mounting frame 200. The power supply box 100 includes a box body 10 and an electrical connection module 80 disposed inside the box body 10. The electrical connection module 80 is used for electrical connection with the display module 300 to realize power supply and signal conduction to the display module 300. The power supply box 100 includes a box body 10, a front cover 20, a rear cover 30, and a connecting assembly 40. The box body 10 is mounted on the mounting frame 200. The two sides of the box body 10, which are arranged opposite each other in the thickness direction, are respectively provided with a first opening (not shown in the figure) and a second opening (not shown in the figure). The first opening faces the front side of the mounting frame 200, and the second opening faces away from the mounting frame 200. The front cover 20 is detachably installed at the first opening of the box body 10 for closing the first opening. The rear cover 30 is rotatably disposed at the second opening of the box body 10 for opening or closing the second opening. The connecting assembly 40 includes a first connecting part 41 and a second connecting part 42. The first connecting part 41 is disposed on the box body 10, and the second connecting part 42 is disposed on the rear cover 30. When the rear cover 30 is rotated to one side of the box body 10, the first connecting part 41 and the second connecting part 42 are connected, so that the rear cover 30 can be positioned and fixed to one side of the box body 10.

[0037] Thus, during post-maintenance of the power supply box 100, the rear cover 30 can be flipped to one side of the box body 10 to expose the electrical connection module 80 without disassembling the entire power supply box 100 or the rear cover 30, reducing the number of parts that need to be removed and improving the work efficiency of maintenance personnel. It is understandable that reducing the number of parts that need to be removed can effectively improve the safety of maintenance personnel during work. Furthermore, the first connecting part 41 is connected to one side of the box body 10, and the second connecting part 42 connects the rear cover 30 to the same side of the box body 10. When the rear cover 30 is rotated to one side of the box body 10, the first connecting part 41 and the second connecting part 42 connect, allowing the rear cover 30 to be positioned and fixed to one side of the box body 10. This prevents the rear cover 30 from shaking or reclosing the second opening when it is flipped to one side of the box body 10, reducing the interference of the rear cover 30 with maintenance work and improving the convenience for maintenance personnel to repair the power supply box 100. In addition, the front cover 20 is detachably connected to the box body 10, which makes it easy for maintenance personnel to remove the front cover 20 to perform front maintenance on the power box 100, so that the power box 100 can meet the maintenance needs of both front and rear maintenance.

[0038] In some embodiments, please refer to Figure 2 The power supply box 100 has a rectangular structure, but it can also be circular or elliptical. Furthermore, the length of the power supply box 100 is aligned with the length of the mounting frame 200, allowing the power supply box 100 to be horizontally mounted on the mounting frame 200. This enables maintenance personnel to repair the internal components of the power supply box 100 from the same height on the mounting frame 200, improving the convenience of maintenance personnel in repairing the power supply box 100.

[0039] In some embodiments, please refer to Figure 5 and Figure 6 The housing 10 has a rectangular structure and a receiving cavity 11. A first opening and a second opening are connected to the receiving cavity 11. The edge of the first opening of the housing 10 is fixed to the side of the mounting frame 200 opposite to the display module 300 by multiple bolts or screws. The electrical connection module 80 is housed in the receiving cavity 11 and can be electrically connected to the display module 300 to ensure that the display module 300 can display. The bottom of the housing 10 is provided with a cable inlet pipe 12, which is connected to the receiving cavity 11. External cables extend into the receiving cavity 11 through the cable inlet pipe 12 and are electrically connected to the electrical connection module 80.

[0040] In some embodiments, the front cover 20 is a shell-like structure. The front cover 20 is installed on the periphery of the first opening of the housing 10 by multiple bolts or screws, realizing a detachable connection between the front cover 20 and the housing 10, which facilitates maintenance personnel to remove the front cover 20 for front maintenance of the power supply box 100. The front cover 20 has multiple through holes 22 for the electrical connectors of the power supply module 80 to pass through the through holes 22 and be electrically connected to the display module 300.

[0041] In this embodiment, a first annular groove (not shown in the figure) is provided circumferentially on the side wall of the front cover 20 facing the housing 10. A first sealing member 71 is engaged in the first annular groove, and the first sealing member 71 can abut against the edge of the first opening of the housing 10 to seal the first opening. In this way, the sealing performance of the power box 100 is improved, which can effectively prevent external moisture or impurities from entering the accommodating cavity 11 through the first opening, reducing the possibility of external moisture or impurities entering the accommodating cavity 11 and damaging the electrical connection module 80.

[0042] In other embodiments, the first seal 71 may be configured as a rectangular sealing ring or as a metal gasket, as long as it can improve the sealing performance between the front cover 20 and the housing 10.

[0043] In some embodiments, the rear cover 30 is a shell-like structure, and the upper sidewall of the rear cover 30 is rotatably connected to the upper sidewall of the housing, so that the rear cover 30 can be rotated to open or close the second opening.

[0044] In this embodiment, please refer to Figure 5 and Figure 6 The rear cover 30 has a second annular groove (not shown in the figure) circumferentially formed on the side wall facing the housing 10. A second sealing element 72 is engaged within the second annular groove, and the second sealing element 72 abuts against the edge of the second opening of the housing 10 to seal the second opening. This further improves the sealing performance of the power supply box 100, effectively preventing external moisture or impurities from entering the accommodating cavity 11 through the second opening 13, and reducing the possibility of external moisture or impurities entering the accommodating cavity 11 and damaging the electrical connection module 80.

[0045] In other embodiments, the second seal 72 may be configured as a rectangular sealing ring or a metal gasket, as long as it can improve the sealing performance between the rear cover 30 and the housing 10.

[0046] In some embodiments, please refer to Figure 4 A heat-conducting element 31 is provided on the side wall of the back cover 30 facing the box body 10. The heat-conducting element 31 is used to resist the electrical connection module 80. The heat generated by the electrical connection module 80 can be conducted to the back cover 30 through the heat-conducting element 31, so that the heat will not accumulate on the electrical connection module 80.

[0047] In other embodiments, the heat-conducting element 31 may be configured as thermally conductive silicone or other thermally conductive materials with superior thermal conductivity, as long as the heat generated by the electrical connection module 80 can be conducted to the back cover 30.

[0048] In some embodiments, please refer to Figure 3The back cover 30 has multiple heat dissipation teeth 32 on the side away from the heat conductor 31. The multiple heat dissipation teeth 32 are vertically arranged on the back cover 30 to dissipate the heat conducted from the heat conductor 31 to the back cover 30, gradually reduce the internal temperature of the power box 100, prevent the power box 100 from being damaged due to excessive internal temperature, ensure the working stability of the components inside the power box 100, and ensure the display effect of the display module 300.

[0049] In some embodiments, please refer to Figure 3 The first connecting part 41 is fixed to the upper end of the box body 10, and the second connecting part 42 is fixed to the upper end of the rear cover 30. When the rear cover 30 rotates relative to the box body 10 to the upper end of the box body 10, the first connecting part 41 and the second connecting part 42 mate, so that the rear cover 30 can be positioned and fixed at the upper end of the box body 10, which facilitates maintenance personnel to repair the electrical connection module 80.

[0050] In some embodiments, multiple first connecting portions 41 are spaced apart at the upper end of the housing 10, and multiple second connecting portions 42 are spaced apart at the upper end of the rear cover 30. The number of first connecting portions 41 and second connecting portions 42 is the same, and one first connecting portion 41 is connected to one second connecting portion 42. This improves the stability of the rear cover 30 in positioning and fixing it at the upper end of the housing 10, making it less likely for the rear cover 30 to shift or detach from the upper end of the housing 10.

[0051] In this embodiment, the first connecting part 41 can be configured as a magnet, and the second connecting part 42 can be configured as a metal connecting piece. When the rear cover 30 is flipped to the upper end of the box body 10, the first connecting part 41 and the second connecting part 42 can magnetically engage, so that the rear cover 30 can be positioned and fixed at the upper end of the box body 10. Alternatively, the first connecting part 41 and the second connecting part 42 can both be configured as magnets.

[0052] In some embodiments, when the first connecting part 41 is configured as a magnet, rubber is wrapped around the magnet to prevent the magnet from being damaged or falling off due to collision. In addition, the rubber can also reduce the impact of the magnet on the electrical connection module 80 inside the power supply box 100, ensuring the stable operation of the electrical connection module 80 inside the power supply box 100.

[0053] In another embodiment, the first connecting part 41 may be a mating groove located on the upper end of the box body 10, and the second connecting part 42 may be configured as a mating protrusion located on the upper end of the rear cover 30. When the rear cover 30 is flipped to the upper end of the box body 10, the mating protrusion can engage with the mating groove, so that the rear cover 30 can be positioned and fixed on the upper end of the box body 10. The structure of the first connecting part 41 and the second connecting part 42 may also have other forms, as long as they can achieve detachable docking between the box body 10 and the rear cover 30.

[0054] In other embodiments, the first connecting part 41 may also be disposed at the bottom of the box body 10, and the second connecting part 42 may be disposed at the bottom of the rear cover 30. The first connecting part 41 may also be disposed on one side of the box body 10 along its length, and the second connecting part 42 may be disposed on one side of the rear cover 30, so that it can be connected with the first connecting part 41.

[0055] In some embodiments, see 6 and Figure 8 The power supply box 100 also includes a rotating connector 50, which comprises a first connecting plate 51, a second connecting plate 52, and a rotating shaft 53. Both the first connecting plate 51 and the second connecting plate 52 are rotatably connected to the rotating shaft 53. The first connecting plate 51 is fixed to one side of the box body 10, and the second connecting plate 52 is fixed to one side of the rear cover 30. The first connecting plate 51 and the rear cover 30 can rotate around the axis of the rotating shaft 53, allowing the rear cover 30 to move relatively closer to or further away from the second opening 13, thus achieving a rotatable connection between the rear cover 30 and the box body 10. In this way, opening the box body 10 by rotation makes subsequent maintenance simpler and more convenient, improving the maintenance efficiency of the power supply box 100.

[0056] When the first connecting part 41 is located at the upper end of the box body 10 and the second connecting part 42 is located at the upper end of the rear cover 30, the first connecting plate 51 is fixed to the upper end of the box body 10 and the second connecting plate 52 is fixed to the upper end of the rear cover 30, allowing the rear cover 30 to rotate to the upper end of the box body 10. Alternatively, when the first connecting part 41 is located at the bottom of the box body 10 and the second connecting part 42 is located at the bottom of the rear cover 30, the first connecting plate 51 is fixed to the upper end of the box body 10 and the second connecting plate 52 is fixed to the upper end of the rear cover 30, allowing the rear cover 30 to rotate to the bottom of the box body 10.

[0057] In some embodiments, see 6 and Figure 7 The power supply box 100 also includes a locking structure 60, which includes a first latching member 61 and a second latching member 62. The first latching member 61 is fixed to the bottom of the rear cover 30 by screws or bolts. The first latching member 61 includes a latching part 611 and a pressing part 612 connected to each other. When the pressing part 612 is pressed, the latching part 611 moves away from the rear cover 30. The second latching member 62 is fixed to the box body 10 by screws or bolts. The second latching member 62 is provided with a limiting part 621. The latching part 611 can disengage from the limiting part 621 when the pressing part 612 is pressed, so that the first latching member 61 and the second latching member 62 disengage from each other, and the rear cover 30 is no longer fixed to the box body 10. The rear cover 30 can rotate around the axis of the rotating shaft 53, thereby opening the second opening for subsequent maintenance.

[0058] The locking structure 60 can be a latch lock.

[0059] In some embodiments, a locking structure 60 may be provided between the back cover 30 and the box body 10, or two or more locking structures 60 may be provided.

[0060] For example, two engaging structures 60 are provided between the back cover 30 and the box body, and the two engaging structures 60 are arranged symmetrically to each other. The two engaging structures 60 can ensure the tight connection between the back cover 30 and the box body 10 and prevent the back cover 30 from separating from the box body 10.

[0061] Please see Figure 9 and Figure 10 This application also provides a display device 1000, including the aforementioned power supply box 100, mounting frame 200, and display module 300. The display module 300 is mounted on the front side of the mounting frame 200, and the power supply box 100 is located on the side of the mounting frame 200 opposite to the display module 300. The specific details of the power supply box 100 are as described in the above embodiments. Since the power supply box 100 adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be elaborated further here.

[0062] In this embodiment, two power supply boxes 100 are provided, and the two power supply boxes 100 are arranged laterally on the mounting frame 200. The length direction of the power supply box 100 is consistent with the length direction of the mounting frame 200.

[0063] In other embodiments, the number of power supply boxes 100 can be set in various ways, such as 3, 4, 5 or more, and is not limited to the above-mentioned number.

[0064] In this way, by setting up multiple power boxes 100, the power demand can be evenly distributed to the electrical connection modules 80 in each power box 100, avoiding overload of current on a single electrical connection module 80 and improving the working stability of the power box 100.

[0065] In some embodiments, multiple power supply boxes 100 integrate high and low voltage modules (not shown in the figure). The high and low voltage modules are electrically connected to the display module 300 and are responsible for providing a stable power supply and signal transmission to the display module 300, ensuring that the electrical components inside the power supply box 100 and the display module 300 can operate stably.

[0066] In this embodiment, please refer to Figure 9 and Figure 10The mounting frame 200 includes four support beams 210 connected end-to-end, forming a rectangular frame structure. The mounting frame 200 also includes four mounting beams 220, one vertical beam 230, and one horizontal beam 240. The horizontal beam 240 is fixed to the mounting frame 200, and its length is aligned with that of the mounting frame 200. The housings 10 of both power boxes 100 are mounted to the horizontal beam 240 on the side facing the mounting frame 200 using bolts or screws.

[0067] Furthermore, the crossbeam 240 is provided with two mounting holes 241, which are spaced apart in the horizontal direction. One mounting hole 241 corresponds to a through hole 22 on the front cover 20, so that the electrical connector of the electrical connection module 80 in the power supply box 100 can pass through the through hole 22 and the mounting hole 241 in sequence to connect with the display module 300.

[0068] It should be noted that the mounting frame 200 can have a length direction, a width direction and a height direction. When the display module 300 is viewed from the front, the horizontal direction is the length direction of the mounting frame 200 and the vertical direction is the height direction of the mounting frame 200.

[0069] In some embodiments, please refer to Figure 9 and Figure 10 The vertical beam 230 is vertically fixed in the middle of the mounting frame 200, and its two ends are respectively connected to two vertically opposite support beams 210. Two power supply boxes 100 are respectively located on opposite sides of the vertical beam 230. A through hole 231 is also provided on the middle side wall of the support beam 210. A cable guide 250 is provided within the through hole 231, and the cable guide 250 has a cable passage cavity 251 for cables to pass through. The two opposite ends of the cable guide 250 in the horizontal direction are respectively connected to the two power supply boxes 100 on both sides of the vertical beam 230, allowing cables in the receiving cavity 11 of one power supply box 100 to extend into the power supply box 100 on the other side through the cable passage cavity 251.
