[0068] To solve the problems in the above background art, the utility model provides a kind of glueless waterproof power box and display device, to solve the technical problems that the power box of existing display screen occupies large space, cost is higher and poor waterproof performance.For the purpose, technical scheme and advantage of the utility model, further detailed description of the technical scheme in the embodiment of the utility model is described in the following examples and combined with the drawings.It should be understood that the specific embodiments described herein are only used to explain the utility model, and not used to limit the utility model.

[0069] As Figure 1 And Figure 2 The utility model provides a kind of glueless waterproof power box, for installing and protecting multiple power module 8 and control module 9, wherein, Figure 1 Different angles of the glueless waterproof power box are shown in the figure, Figure 2 The explosion schematic view of the glueless waterproof power box is shown.

[0070] As Figure 1 And Figure 2 The glueless waterproof power box includes box body 1, cover plate 2, upper end cover 3, upper waterproof cover 4, lower end cover 5 and lower waterproof cover 6.

[0071] The cover plate 2 is detachably connected with the box body 1 and forms a cavity 14 with the box body 1, which can accommodate a plurality of power modules 8 and a plurality of control modules 9. The upper end cover 3 is detachably connected with the box body 1 and the cover plate 2 respectively, and the lower end cover 5 is detachably connected with the box body 1 and the cover plate 2 respectively. As shown in Figure 5 The top of the upper end cover 3 is provided with a first protruding part 31, which is hollow inside and communicates with the cavity 14. As shown in Figure 8 The bottom of the lower end cover 5 is provided with a second protruding part 51, which is hollow inside and communicates with the cavity 14. As shown in Figure 7 The upper waterproof cover 4 is installed on the first protruding part 31; as shown in Figure 10 The lower waterproof cover 6 is installed on the second protruding part 51.

[0072] In the prior art, in order to meet the size requirements of display devices such as display screens, a plurality of display modules are usually assembled together. Each display module is connected with a power module for power supply, and each power module is assembled with a power box. However, the use of multiple power boxes occupies a large space and has a high cost. To solve this technical problem, the present utility model provides a glue-free waterproof power box, which can fix a plurality of power modules 8 and a plurality of control modules 9 together in the cavity 14.

[0073] In an embodiment, the box body 1 and the cover plate 2 adopt a profile structure. It should be understood that the profile refers to a solid straight bar formed by plastic processing of metal, having a certain cross-sectional shape and size, and also includes iron or steel and objects with certain strength and toughness made of materials through processes such as rolling, extrusion, and casting. According to the production method, the profile can be divided into hot-rolled profile, cold-bent profile, cold-rolled profile, cold-drawn profile, and extruded profile. Among them, the extruded profile refers to putting the metal blank into the extrusion cylinder, applying pressure through the extrusion rod, and extruding it from the die hole of the die to form a profile with the required shape and size, which is suitable for producing various complex cross-section profiles and has the characteristics of high production efficiency and low cost. In this embodiment, the profile structure can process the box body 1 and the cover plate 2 into a size that can install different numbers and sizes of power modules 8 and control modules 9, thereby adapting to display devices of different sizes and solving the technical problems of large space occupation and high cost of the power box of the existing display screen.

[0074] In an embodiment, the glue-free waterproof power box adopts a clamping groove structure to install and fix each power module 8 and each control module 9. Specifically, as shown in Figure 3As shown, the box body 1 comprises a back plate 11, a first side plate 12 and a second side plate 13, and the back plate 11 is provided with first clamping grooves 111 on both sides. A plurality of supporting members 7 are fixed at designated positions of the first clamping grooves 111 to fix and support the power modules 8 or the control modules 9. For example, four supporting members 7 are fixed at designated positions of the first clamping grooves 111 respectively, and abut against four corners of a power module 8 respectively, so that the power module 8 is press-fitted in the box body 1.

[0075] In a preferred embodiment, as shown in Figure 3 The supporting member 7 is provided with a fastening hole 71 (not shown) and a limiting portion 72. The first fastener 73 is inserted into the fastening hole 71 and is pressed into the designated position of the first clamping groove 111, so that the supporting member 7 is fixed at the designated position of the first clamping groove 111. At this time, the limiting portion 72 abuts against the power module 8 or the control module 9, thereby fixing and supporting the power module 8 or the control module 9. It should be noted that the first fastener 73 is matched with the first clamping groove 111. When the first fastener 73 is pressed into the first clamping groove 111, the first clamping groove 111 limits the first fastener 73, so that the supporting member 7 has a certain strength and can support and limit the power module 8 or the control module 9.

[0076] In this embodiment, by adjusting the different positions of the supporting member 7 fixed in the first clamping groove 111, power modules 8 or control modules 9 of different sizes can be fixed.

[0077] In order to protect each power module 8 and each control module 9, the glue-free waterproof power box is designed with a waterproof structure, which utilizes gravity, drop structure and unloading space to prevent water from entering and to naturally flow out the water condensed on the box body and the cover plate 2 by the power module 8.

[0078] In an embodiment, as shown in Figure 7 The upper waterproof cover 4 is installed on the first protruding portion 31 and forms a gap with the side edge and the top of the first protruding portion 31, so that the upper end cover 3 and the upper waterproof cover 4 form a drop structure, and water flows around the upper waterproof cover 4 and flows away from the outside of the back plate 11, the first side plate 12 and the second side plate 13, thereby preventing water from entering the top of the power box.

[0079] In an embodiment, as shown in Figure 7 The outer side of the back plate 11 is provided with a plurality of protruding heat dissipation strips 113, and the gaps between the heat dissipation strips 113 form drainage grooves 114. Meanwhile, as shown in Figure 10As shown, the lower end cover 5 is provided with a plurality of limiting teeth 53 matched with each drainage groove 114. Each limiting tooth 53 is inserted into each drainage groove 114, and one side is abutted with each heat dissipation strip 113, and the other side forms a drainage port 54 communicated with each drainage groove 114. Through each drainage groove 114 and the communicated drainage port 54, water can be more conveniently drained.

[0080] As shown in the drawings, Figure 10 As shown, the lower waterproof cover 6 is installed on the second protruding part 51 and forms a gap with the side edge and the bottom of the second protruding part 51, so that the lower end cover 5 and the lower waterproof cover 6 form a stepped structure. The bottom of the lower waterproof cover 6 is provided with one or more drainage holes 61. When the power module 8 generates heat, the hot air condenses on the box body 1 and the cover plate 2 to form water droplets, which can be drained downward along the box body 1 and the cover plate 2 through the drainage holes 61 under the action of gravity, thereby avoiding the safety hidden danger caused by water droplets remaining in the power box.

[0081] In an embodiment, as shown in the drawings, Figure 6 As shown, the bottom of the upper waterproof cover 4 is provided with an upper air exhaust groove 42 on both sides, and as shown, Figure 9 The top of the lower waterproof cover 6 is provided with a lower air exhaust groove 63 on both sides. The water vapor generated by the heat of the power module 8 can be discharged through the gap between the upper waterproof cover 4 and the upper end cover 3, the gap between the lower waterproof cover 6 and the lower end cover 5, and the upper and lower air exhaust grooves 42 and 63, thereby avoiding the safety hidden danger caused by water droplets remaining in the power box and balancing the air pressure in the power box.

[0082] In addition, each heat dissipation strip 113 outside the back plate 11 can increase the surface area of the back plate 11, and the heat dissipation effect is better, so that the water vapor or water droplets generated by the heat of the power module 8 can be effectively reduced.

[0083] Therefore, the glue-free waterproof power box has better waterproof effect, better heat dissipation effect and better safety performance.

[0084] In an embodiment, the glue-free waterproof power box can also provide a wire arranging function. As shown in the drawings, Figure 5 As shown, the side of the first protruding part 31 is provided with one or more first wire inlet ports 311, and the side of the upper waterproof cover 4 is provided with a second wire inlet port 41 matched with each first wire inlet port 311. Each first wire inlet port 311 and each second wire inlet port 41 form a wire inlet port, and the connecting wires connected to each power module 8 and each control module 9 are pressed and the inlets are unified.

[0085] As shown in the drawings, Figure 8As shown, the side surface of the second protruding part 51 is provided with one or more first wire outlets 511, and the side surface of the lower waterproof cover 6 is provided with second wire outlets 62 matched with the first wire outlets 511. The first wire outlets 511 and the second wire outlets 62 form wire outlets, and the connection wires of the power supply modules 8 and the control modules 9 are pressed and the outlets are unified.

[0086] It should be noted that in the above embodiment, the connection wires of the power supply modules 8 and the control modules 9 are designed to enter from the top of the power supply box and exit from the bottom, but the application does not limit the use of the wire outlets. Users can design the power supply box to exit from the top and enter from the bottom, or to arrange the connection wires of the power supply modules 8 from the top and the connection wires of the control modules 9 from the bottom, etc.
