[0062] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0063] To enable those skilled in the art to better understand the solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0064] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0065] In the description of the embodiments of this application, the words "example" or "for example" are used to indicate exemplification, illustration, or description. Any embodiment or design described as "example" or "for example" in the embodiments of this application is not to be construed as being more preferred or having more advantages than another embodiment or design. The use of the words "example" or "for example" is intended to present relative concepts in a clear manner.

[0066] Furthermore, in the embodiments of this application, "multiple" refers to two or more. Therefore, in the embodiments of this application, "multiple" can also be understood as "at least two". "At least one" can be understood as one or more, such as one, two, or more. For example, including at least one means including one, two, or more, and is not limited to which ones are included. For example, including at least one of A, B, and C, then it could include A, B, C, A and B, A and C, B and C, or A and B and C.

[0067] Display devices, such as LED (light-emitting diode) display devices, typically include an LED display module and a control box. The control box is electrically connected to the LED display module to control the LED display module.

[0068] In related technologies, the control box is located in the LED display module. When it is necessary to perform wiring, maintenance or other operations on the circuit board inside the control box 100, the disassembly of the control box is quite difficult.

[0069] Therefore, in some display devices, the control box casing is divided into two parts: the box body and the cover. The box body and cover are either secured with screws or connected by a snap-fit ​​mechanism, allowing for easy disassembly of the cover for wiring, maintenance, and other tasks. For the former, users need a screwdriver compatible with the screws to install and remove the cover; for the latter, to ensure the control box's aesthetics, the snap-fit ​​mechanism is usually hidden inside the box body after the cover is attached, making disassembly still relatively difficult for users.

[0070] Based on this, in this embodiment of the application, the cover assembly of the control box is installed by the cooperation of the positioning post and the first magnetic chuck, which has the advantages of stable installation and easy disassembly, so as to facilitate maintenance inside the control box. More detailed examples will follow.

[0071] Please refer to Figure 1 First, this application provides a display device, which may include a television, computer monitor, outdoor advertising screen, commercial conference tablet, vehicle display module, etc., and this application does not limit the scope of the display device. The display device includes a bracket assembly 200, an LED display assembly 300, and a control box 100. The LED display assembly 300 is disposed on the bracket assembly 200 and supported by the bracket assembly 200. The control box 100 is mounted on the bracket assembly 200 or the LED display assembly 300, and the control box 100 is electrically connected to the LED display assembly 300.

[0072] Please continue to refer to the following: Figure 2 , Figure 3 and Figure 4 The control box 100 includes a box body assembly 11 and a box cover assembly 12. The box cover assembly 12 covers the box body assembly 11 to form an installation space 1111 between the box cover assembly 11 and the box body assembly 11. One of the box body assembly 11 and the box cover assembly 12 is provided with a first magnetic element 112, and the other of the box body assembly 11 and the box cover assembly 12 is magnetically connected to the first magnetic element 112. Additionally, one of the box body assembly 11 and the box cover assembly 12 is provided with a positioning post 122, and the other of the box body assembly 11 and the box cover assembly 12 is pluggably connected to the positioning post 122.

[0073] Therefore, on the one hand, during the installation of the box body assembly 11 and the box cover assembly 12, the box cover assembly 12 can be quickly positioned and initially fixed by the positioning post 122, and then the stability and reliability of the box cover assembly 12 installation can be ensured by the first magnetic component 112; on the other hand, during the disassembly of the box body assembly 11 and the box cover assembly 12, the box cover assembly 12 can be disassembled simply by picking it up. Thus, it can be seen that the control box 100 of this embodiment, while ensuring the stability and reliability of the box cover assembly 12 installation, also has the advantage of being easy to assemble and disassemble.

[0074] Please continue to refer to Figure 5 In some embodiments, the number of first magnetic elements 112 can be multiple, such as two, three, four, five, six, or even twenty. This application does not limit this. Thus, multiple first magnetic elements 112 can achieve multiple connections and fixations between the lid assembly 12 and the body assembly 11, thereby improving the stability and reliability of the lid assembly 12 installation.

[0075] In some embodiments, at least a portion of the first magnetic elements 112 are arranged along the length direction of the lid assembly 12. It is understood that as the length of the lid assembly 12 increases, the stiffness of the lid assembly 12 decreases accordingly. Therefore, by arranging the first magnetic elements 112 at multiple positions along the length direction of the lid assembly 12, this embodiment of the application can provide better fixation and support for various positions along the length direction of the box assembly 11, thereby improving the stability and reliability of installation at various positions along the length direction of the box assembly 11.

[0076] For example, the lid assembly 12 may have a first magnetic element 112 at both ends and the middle along its length. Optionally, at least some of the first magnetic elements 112 may be evenly spaced along the length of the lid assembly 12, but this embodiment does not limit this.

[0077] In some embodiments, a first magnetic element 112 is provided on each side edge of the lid assembly 12 in the width direction. It is understood that, as mentioned above, as the length of the lid assembly 12 increases, the rigidity of the lid assembly 12 will decrease accordingly; therefore, providing a first magnetic element 112 on each side edge of the lid assembly 12 in the width direction can also be understood as providing a first magnetic element 112 on each long side edge of the box body assembly 11, thereby improving the stability and reliability of the lid assembly 12 during installation.

[0078] For example, the housing assembly 11 has two first long sides 1112 extending along the length direction. The two long sides are arranged opposite each other along the width direction of the housing assembly 11, and a plurality of first magnetic elements 112 are spaced apart on each first long side 1112.

[0079] Please refer to this as well. Figure 4 and Figure 5 In some embodiments, a first connecting portion 1113 protrudes from the inner wall of the box assembly 11 and one of the box assembly 11. The first connecting portion 1113 has a positioning hole 1114, and a positioning post 122 passes through the positioning hole 1114. Therefore, compared to the positioning hole 1114 being formed on the outer wall of the box assembly 11 or the box cover assembly 12, the embodiments of this application can, on the one hand, avoid the positioning hole 1114 and the positioning post 122 being exposed and affecting the aesthetics of the control box 100, and on the other hand, reduce the openings on the surface of the control box 100, thereby improving the sealing effect and safety performance of the control box 100.

[0080] Please refer to this as well. Figure 4 and Figure 6 In some embodiments, a second connecting portion 1211 protrudes from the inner wall of the other of the box body assembly 11 and the lid assembly 12, and the second connecting portion 1211 is provided with a positioning post 122. The second connecting portion 1211 is also provided with a second magnetic element 123, which is magnetically connected to the first magnetic element 112. Therefore, compared with opening holes on the outer wall of the box body assembly 11 or the lid assembly 12 to install the positioning post 122 and the second magnetic element 123, the embodiments of this application can reduce the openings on the surface of the control box 100, thereby improving the aesthetics, sealing effect and safety performance of the control box 100.

[0081] Specifically, one of the first magnetic element 112 and the second magnetic element 123 may be a magnet and the other may be a magnetic metal element. Alternatively, both the first magnetic element 112 and the second magnetic element 123 may be magnets. This application does not limit this.

[0082] It should be noted that, as mentioned above, one of the box body assembly 11 and the box lid assembly 12 is provided with a first magnetic element 112. Therefore, either the box body assembly 11 or the box lid assembly 12 may be provided with the first magnetic element 112. Correspondingly, the box body assembly 11 may be provided with a first connecting portion 1113 and the box lid assembly 12 may be provided with a second connecting portion 1211, or the box body assembly 11 may be provided with a second connecting portion 1211 and the box lid assembly 12 may be provided with a first connecting portion 1113. This application embodiment does not limit this.

[0083] For example, the box assembly 11 has a first long side 1112 extending along its length, and a first connecting portion 1113 is disposed on the first long side 1112. The lid assembly 12 has a second long side 1212 extending along its length, and a second connecting portion 1211 is disposed on the second long side 1212. Therefore, compared to the first connecting portion 1113 being disposed in the middle of the box assembly 11, this embodiment allows the first magnetic element 112 to be closer to the sides of the box assembly 11 and the lid assembly 12, thereby preventing the sides of the lid assembly 12 from warping up, ultimately improving the aesthetics and reliability of the lid assembly 12 during installation.

[0084] As mentioned above, in some embodiments, at least some of the first magnetic elements 112 are arranged along the length of the lid assembly 12. Therefore, multiple first magnetic elements 112 may be arranged at intervals in the first connecting portion 1113.

[0085] It should also be noted that the control box 100 may not have the first connecting part 1113 and the second connecting part 1211; correspondingly, the first magnetic element 112 and the like can be directly disposed on the inner wall of the corresponding box assembly 11 or box cover assembly 12; for example, the first magnetic element 112 can be directly installed on the first long side 1112, and this application embodiment does not limit this.

[0086] In some embodiments, the lid assembly 12 is further provided with a third magnetic element 124, which is used to magnetically connect with an external magnetic tool for the magnetic tool to attract and fix the lid assembly 12. Thus, the user can use a magnetic tool to pick up and put down the lid assembly 12 during the process of assembling and disassembling the lid assembly 12.

[0087] For example, the lid assembly 12 may include a lid 121 and a third magnetic element 124. The lid 121 includes two second long sides 1212, each of which has a second connecting portion 1211 integrally formed thereon. The third magnetic element 124 is located between the two second long sides 1212 and at the middle of the lid 121 along its length.

[0088] The third magnetic component 124 may include at least one of magnetic metal and magnet, but this application embodiment does not limit this.

[0089] It should be noted that the lid assembly 12 may also omit the third magnetic element 124. For example, the lid assembly 12 may also have a hand position (not shown in the figure) for the user to pick up, put down and hold the lid assembly 12.

[0090] In some embodiments, the control box 100 further includes a flexible connector 13. One end of the flexible connector 13 is fixed to the box body assembly 11, and the other end of the flexible connector 13 is fixed to the box cover assembly 12. The flexible connector 13 is used to limit the movement distance of the box cover assembly 12 when it is opened.

[0091] Therefore, the box assembly 11 can be prevented from being lost after the box assembly 11 is opened, or when the display device vibrates during transportation or other processes, causing the box assembly 111 to become loose.

[0092] The flexible connector 13 may include a rope or any other type of flexible connector 13, and this application embodiment does not limit it.

[0093] In some embodiments, one end of the flexible connector 13 is fixed to the first connecting portion 1113, and the other end of the flexible connector 13 is fixed to the second connecting portion 1211. Of course, the flexible connector 13 can also be connected to any other position of the box assembly 11, and the flexible connector 13 can also be connected to any other position of the lid assembly 12. This application embodiment does not limit this.

[0094] In some embodiments, the control box 100 also includes a sound-generating unit 14, thereby further improving the integration of the control box 100 by integrating the sound-generating unit 14 into the control box 100, and also reducing the maintenance difficulty of the sound-generating unit 14 by taking advantage of the easy disassembly and assembly of the cover assembly 12.

[0095] In some implementations, such as Figure 3 As shown, the housing assembly 11 has a mounting surface 1115 for mounting and fixing. The sound-emitting unit 14 is inclined to the mounting surface 1115. Taking the mounting surface 1115 of the housing assembly 11 as the bottom surface as an example, the sound-emitting surface of the sound-emitting unit 14 can be inclined upward, so that the sound waves of the sound-emitting unit 14 are reflected by the ceiling, thereby increasing the sound propagation distance.

[0096] For example, the lid assembly 12 may be inclined to the mounting surface 1115, and the sound-emitting unit 14 may be mounted on the lid assembly 12.

[0097] In some implementations, the sound-generating unit 14 may include a full-range speaker to meet audio integration requirements.

[0098] In some embodiments, the sound emission angle of the sound-emitting unit 14 in the vertical direction can be from 55° to 85°. For example, the sound emission angle of the sound-emitting unit 14 in the vertical direction can be 55°, 58°, 59.7°, 60°, 65°, 67.8°, 69.5°, 70°, 71.5°, 75°, 78.5°, 80°, or 85°, and this application embodiment does not limit this. This allows the sound waves generated by the sound-emitting unit 14 to have a larger sound field area.

[0099] In some embodiments, the sound emission angle of the sound-emitting unit 14 in the horizontal direction can be greater than or equal to 150°. For example, the sound emission angle of the sound-emitting unit 14 in the vertical direction can be 150°, 158°, 159.7°, 160°, 163.5°, 165.8°, 170°, 173.5°, 175°, or 178.5°, and this application embodiment does not limit this. This allows the sound waves generated by the sound-emitting unit 14 to have a larger sound field area.

[0100] In some implementations, such as Figure 5 As shown, the control box 100 also includes at least one of a wireless communication component 15, an infrared component 16, a button component 17, and an electrical interface 18, thereby improving the integration of the control box 100 and reducing the maintenance difficulty of components such as the wireless communication component 15, the infrared component 16, the button component 17, and the electrical interface 18 by taking advantage of the easy disassembly and assembly of the cover component 12.

[0101] In some embodiments, the sound-emitting surface of the sound-emitting unit 14 faces the first side of the control box 100. The wireless communication component 15 faces the first side of the control box 100. It is understood that the sound-emitting surface of the sound-emitting unit 14 is usually facing the user in order to transmit sound waves to the user, and therefore the wireless communication component 15 may also face the user in order to receive Bluetooth signals transmitted by the user's remote control, smart terminal, etc.

[0102] For example, both the sound-generating unit 14 and the wireless communication component 15 are mounted on the cover assembly 12.

[0103] The wireless communication component 15 may include a Bluetooth component, a WIFI (Wireless Fidelity) component, an NFC (Near Field Communication) component, and a UWB (Ultra Wide Band) component, etc., and this application embodiment does not limit it.

[0104] In some embodiments, the sound-emitting surface of the sound-emitting unit 14 faces the first side of the control box 100. The infrared component 16 faces the first side of the control box 100. It is understood that the sound-emitting surface of the sound-emitting unit 14 is usually facing the user in order to emit sound waves to the user, so the infrared component 16 can also face the user in order to receive infrared signals emitted by the user's remote control, smart terminal, etc.

[0105] For example, both the sound-emitting unit 14 and the infrared component 16 are mounted on the cover assembly 12.

[0106] In some embodiments, the sound-emitting surface of the sound-emitting unit 14 faces a first side of the control box 100. At least a portion of the button assembly 17 faces the first side of the control box 100. It is understood that since the sound-emitting surface of the sound-emitting unit 14 is generally facing the user in order to emit sound waves to the user, at least a portion of the button assembly 17 may also face the user in order to facilitate user pressing operation.

[0107] For example, the sound-generating unit 14 and at least part of the button assembly 17 are both mounted on the cover assembly 12.

[0108] Of course, some of the button components 17 and the sound-emitting unit 14 may face the same side of the control box 100, while some of the button components 17 and the sound-emitting unit 14 may face different sides of the control box 100. This application embodiment does not limit this.

[0109] In some embodiments, the sound-emitting surface of the sound-emitting unit 14 faces a first side of the control box 100. At least a portion of the electrical interface 18 faces the first side of the control box 100. It is understood that the sound-emitting surface of the sound-emitting unit 14 is generally oriented towards the user in order to emit sound waves to the user, and therefore at least a portion of the electrical interface 18 may also face the user in order to facilitate user operation.

[0110] For example, the sound-generating unit 14 and at least part of the electrical interface 18 may both be mounted on the cover assembly 12.

[0111] In some implementations, the electrical interface 18 may include a TYPA-C interface, a USB (Universal Serial Bus) interface, an aviation interface, an HDMI (High Definition Multimedia Interface), a DC (direct current) interface, etc., and this application embodiment does not limit this.

The window cover 113 is movably installed on the housing 111 and is used to open or close the operation window 1117.

[0114] Therefore, one possible wiring method for the control box 100 is as follows:

[0115] First, open the operation window 1117; then, insert the external wire of the control box 100 into the installation space 1111 through the wiring hole 1116; next, connect one end of the wire inserted into the installation space 1111 through the operation window 1117; finally, close the operation window 1117. Therefore, the box assembly 11 of this embodiment also has the advantages of easy wiring and maintenance.

[0116] The window cover 113 can be movably installed on the box body 111 by either a rotating connection or a sliding connection; this application embodiment does not limit this.

[0117] In some embodiments, the housing assembly 11 further includes a resilient seal 114, which is mounted in the wiring hole 1116. The resilient seal 114 has a slit 1141. This allows wires to pass through the slit 1141 and extend into the control box 100, while the elasticity of the resilient seal 114 can seal the gap in the wiring hole 1116 as much as possible.

[0118] In some embodiments, the outer surface of the control box 100 may be provided with a decorative structure to enhance the aesthetics of the control box 100.

[0119] Decorative structures may include decorative patterns, decorative elements, and decorative layers, etc., and the embodiments of this application do not limit these.
