[0010] Optionally, the limiting body extends into the pull-out box through the opening; when the pull-out box is in the exposed position, the limiting body prevents the pull-out box from continuing to move toward the preset edge by contacting the inner wall surface of the pull-out box.

[0011] Optionally, one of the display body and the pull-out box is provided with a slider, and the other is provided with a groove. The pull-out box slides on the display body in a preset direction by sliding along the groove via the slider.

[0012] Optionally, the slider is provided on the back panel, and the slide groove is provided on the pull-out box; the length of the slider is less than the length of the slide groove.

[0013] Optionally, a second limiting member is provided in the slide groove; when the pull-out box is in the exposed position, the second limiting member prevents the pull-out box from continuing to move toward the preset edge by contacting the surface of the slide bar away from the preset edge.

[0014] Optionally, one of the display body and the pull-out box is provided with a guide strip, and the other is provided with a guide groove. The guide strip passes through the guide groove and can slide in the guide groove in a preset direction.

[0015] Optionally, a guide strip is provided in the pull-out box, a guide rail is provided on the back panel, and a guide groove is provided on the guide rail; a limiting groove is provided on the side of the pull-out box along a preset direction, the limiting groove having a first limiting groove wall and a second limiting groove wall spaced apart along the preset direction, the second limiting groove wall being located on the side of the first limiting groove wall away from the preset edge; the guide rail has a limiting structure, the limiting structure passing through the limiting groove, used to block the pull-out box in the hidden position from moving away from the preset edge by contacting the first limiting groove wall, and used to block the pull-out box in the exposed position from moving towards the preset edge by contacting the second limiting groove wall; and / or, the display device further includes: an adapter, provided inside the pull-out box; a transmitter card, provided inside the pull-out box, the transmitter card being electrically connected to the adapter via a control component and electrically connected to the display body; and a WiFi module, provided in the pull-out box and electrically connected to the control component.

[0016] The beneficial effects of the display device provided in this application are as follows: On the one hand, by using the pull-out box and control components used in this application, the control components no longer occupy the space inside the lower profile. Compared with the method of fixing the control components inside the lower profile of the display body, the structural design in this application effectively reduces the width of the lower profile, which is conducive to realizing the ultra-narrow bezel design and improving the screen ratio and visual effect of the display device.

[0017] On the other hand, the first limiting component effectively prevents the pull-out box in the hidden position from moving towards the preset edge, thus ensuring that the pull-out box remains stably in the hidden position. This structural design prevents the pull-out box from moving towards the preset edge due to gravity during the transportation and installation of the display device, ensuring the stability and reliability of the pull-out box in the hidden position on the display body.

The terminology used in this application is for the purpose of describing specific embodiments only and is not intended to limit the application. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] As described in the background section, a display device is a device capable of converting electrical signals into visual information. In related technologies, a display device includes a display body and control components (such as a control circuit board), with the control components typically fixedly mounted inside the lower profile of the display body. However, this assembly method prevents the width of the lower profile from being reduced, thus making it impossible to achieve an ultra-narrow bezel design for the display body.

[0043] Referring to Figures 1 to 3, in order to solve the above-mentioned problems, according to one aspect of this application, an embodiment of this application provides a display device, which includes a display body 100, a pull-out box 200, a control member 300, and a first limiting member 400. The display body 100 has a back plate 110 and a preset edge 120. The pull-out box 200 is disposed on the back plate 110 and can move closer to or further away from the preset edge 120 in a preset direction. The pull-out box 200 has a hidden position, and when the pull-out box 200 is in the hidden position, the back plate 110 covers the pull-out box 200. The control member 300 is disposed on the pull-out box 200. The first limiting member 400 is disposed on the back plate 110 and is used to prevent the pull-out box 200 in the hidden position from moving toward the preset edge 120.

[0044] In this embodiment, the display device is an LED display (LED stands for Light Emitting Diode). In other embodiments, the display device may also be any one of a liquid crystal display, an OLED display (OLED stands for Organic Light Emitting Diode), or a plasma display. The display body 100 is the main structure used to display visual information. The pull-out box 200 can slide along a preset direction on the back plate 110 using cooperating guide rails and guide strips. The preset direction is parallel to the length direction of the display body 100, and the preset edge 120 is the left or right edge of the display body 100; in other embodiments, the preset direction may also be parallel to the width direction of the display body 100, in which case the preset edge 120 is the upper or lower edge of the display body 100.

[0045] The control component 300 is a control circuit board, which can be fixedly installed on the surface or inside of the pull-out box 200 by screw connection, plug-in connection or soldering. The first limiting member 400 can be a screw that is detachably installed on the back plate 110 by means of thread engagement; when it is necessary to prevent the movement of the pull-out box 200 in the hidden position, the first limiting member 400 is installed on the back plate 110; when it is not necessary to prevent the movement of the pull-out box 200 in the hidden position, the first limiting member 400 is removed from the back plate 110 so that the pull-out box 200 moves toward the preset edge 120. The first limiting member 400 can also be a magnetic member. In this case, a metal plate that cooperates with the magnetic member is fixedly installed on the pull-out box 200. When it is necessary to prevent the pull-out box 200 from moving in the hidden position, the magnetic member contacts the metal plate, and the magnetic force between the two stabilizes the pull-out box 200 in the hidden position. When it is not necessary to prevent the pull-out box 200 from moving in the hidden position, the pull-out box 200 is moved by applying a magnetic force greater than that between the magnetic member and the metal plate. In addition, the pull-out box 200 in Figure 3 is in the hidden position.

[0046] On the one hand, by using the pull-out box 200 and control component 300 used in this application, the control component 300 no longer occupies the space inside the lower profile 150. Compared with the method of fixing the control component 300 inside the lower profile 150 of the display body 100, the structural design in this application effectively reduces the width of the lower profile 150, which is conducive to achieving an ultra-narrow bezel design and improving the screen ratio and visual effect of the display device.

[0047] On the other hand, the first limiting member 400 effectively prevents the pull-out box 200 in the hidden position from moving toward the preset edge 120, thus ensuring that the pull-out box 200 can remain stably in the hidden position. This structural design prevents the pull-out box 200 from moving toward the preset edge 120 due to gravity during transportation and installation of the display device, ensuring the stability and reliability of the pull-out box 200 in the hidden position on the display body 100.

[0048] On the other hand, the pull-out box 200 is hidden when not in use, and is covered and protected by the back panel 110. This effectively prevents external dust, moisture, and other impurities from corroding and damaging the functional components such as the control unit 300 on the pull-out box 200, extending the service life of the pull-out box 200 and the control unit 300, and improving the reliability and stability of the entire display device. It also ensures that there are no obtrusive exposed components, keeping the overall appearance of the display device simple and flat, thus enhancing its aesthetics.

[0049] Referring to Figures 1 to 8, in one embodiment, the first limiting member 400 includes a limiting body 410 and a connecting body 420. The limiting body 410 is disposed on the back plate 110 and protrudes towards the back plate 110 in the direction close to the pull-out box 200. The limiting body 410 is connected to the pull-out box 200 in the hidden position through the connecting body 420 to restrict the movement of the pull-out box 200 in the hidden position.

[0050] In this embodiment, the limiting body 410 is a limiting plate, which can be fixedly installed on the back plate 110 by welding, gluing, or screw connection. The connecting body 420 can be a connecting pin capable of elastic deformation. Both the pull-out box 200 and the limiting body 410 are provided with through holes for the connecting body 420 to pass through. The limiting body 410 is detachably connected to the pull-out box 200 by an interference fit between the connecting pin and the wall of the through hole. In other embodiments, the connecting body 420 can also be a magnetic component. In this case, the connecting body 420 is fixedly installed on the limiting body 410, and a metal plate capable of generating a magnetic attraction force with the connecting body 420 is fixedly installed on the pull-out box 200. In addition, the pull-out box 200 in Figure 4 is in a blurred state.

[0051] On the one hand, by connecting the limiting body 410 to the pull-out box 200 through the connector 420, the movement of the pull-out box 200 can be effectively restricted. Whether the display device is subjected to slight vibration during normal use or under the action of external forces that may be generated during transportation or installation, the limiting body 410 and the connector 420 used together can reliably prevent the pull-out box 200 from moving toward the preset edge 120, thus avoiding problems such as component collision and damage that may be caused by the accidental movement of the pull-out box 200.

[0052] On the other hand, the design of the limiting body 410 and the connecting body 420 not only reduces the manufacturing difficulty of the limiting component and the assembly difficulty with the pull-out box 200, but also allows for easy maintenance or replacement of the pull-out box 200 or the control component 300. Simply disconnect the connecting body 420 from the pull-out box 200 to easily pull it out from its hidden position for maintenance. After maintenance, the pull-out box 200 can be quickly and accurately returned to its original position and reconnected to the limiting body 410 via the connecting body 420, restoring its normal limiting function.

[0053] Referring to Figures 1 to 8, in one embodiment, the back panel 110 includes a back panel body 111 and a limiting body 410. The limiting body 410 is disposed on the back panel body 111 and is a bent strip that bends toward the pull-out box 200.

[0054] In this embodiment, the limiting body 410 is a bent strip formed by bending a part of the structure on the back plate 110 toward the pull-out box 200; a notch 112 is formed on the back plate body 111.

[0055] The limiting body 410 is formed by bending directly on the back plate body 111, eliminating the need for a large number of additional independent parts to achieve the limiting function. This not only simplifies the production process, improves production efficiency, and reduces production costs, but also makes the limiting body 410 and the back plate body 111 an integral molded part, reducing potential quality problems caused by the connection of parts and improving product consistency and reliability.

[0056] Referring to Figures 1 to 9, in one embodiment, the connector 420 is a connecting screw, the pull-out box 200 is provided with a first connecting hole 210 for the connector 420 to pass through, and the limiting body 410 is provided with a second connecting hole 411 for the connector 420 to pass through. At least one of the first connecting hole 210 and the second connecting hole 411 is a threaded hole.

[0057] In this embodiment, both the first connecting hole 210 and the second connecting hole 411 are threaded holes; in other embodiments, the first connecting hole 210 is a threaded hole and the second connecting hole 411 is a smooth hole; or the first connecting hole 210 is a smooth hole and the second connecting hole 411 is a threaded hole. The above structural design facilitates the connection and separation of the limiting body 410 and the pull-out box 200, improving the efficiency of assembly and disassembly.

[0058] Referring to Figures 2, 4, 10, and 11, in one embodiment, the control element 300 is disposed inside the pull-out box 200. The surface of the pull-out box 200 near the back panel 110 is provided with an opening 220, which communicates with the interior of the pull-out box 200. The pull-out box 200 has an exposed position. When the pull-out box 200 is in the exposed position, the opening 220 is located on one side of the display body 100 in a preset direction.

[0059] In this embodiment, the control component 300 is fixedly installed inside the pull-out box 200 by means of screw connection, plug-in connection or welding. In addition, the pull-out box 200 in Figures 2 and 10 is in the exposed position.

[0060] When maintenance or replacement of the control component 300 inside the pull-out box 200 is required, the pull-out box 200 is slid to the exposed position; the opening 220 is located on one side of the display body 100, and maintenance personnel can easily access the control component 300 inside the pull-out box 200 through the opening 220 without having to remove the entire pull-out box 200 from the display body 100, which greatly reduces the difficulty and workload of maintenance.

[0061] Referring to Figures 2, 4, 10 and 11, in one embodiment, the limiting body 410 extends into the pull-out box 200 through the opening 220; when the pull-out box 200 is in the exposed position, the limiting body 410 prevents the pull-out box 200 from continuing to move toward the preset edge 120 by contacting the inner wall surface of the pull-out box 200.

[0062] In this embodiment, the pull-out box 200 has a limiting inner wall surface 230, and the limiting body 410 contacts the limiting inner wall surface 230 to prevent the pull-out box 200 from continuing to move towards the preset edge 120. The limiting body 410 provides a dual limiting function, not only restricting the movement of the pull-out box 200 in the hidden position towards the preset edge 120 through cooperation with the connecting body 420, but also restricting the pull-out box 200 in the exposed position from continuing to move towards the preset edge 120, thus preventing the pull-out box 200 from falling off the display body 100 due to accidental collisions, vibrations, or other factors, and ensuring the stability and reliability of the pull-out box 200 in the exposed position on the display body 100. In addition, to improve the limiting effect, the number of limiting bodies 410 can be multiple; the number of connecting bodies 420 is the same as the number of limiting bodies 410, and multiple connecting bodies 420 are respectively provided in a one-to-one correspondence with multiple limiting bodies 410.

[0063] Referring to Figures 2, 4, 7, 10 and 11, in one embodiment, one of the display body 100 and the pull-out box 200 is provided with a slide bar 130, and the other is provided with a slide groove 241. The pull-out box 200 slides on the display body 100 in a preset direction within the slide groove 241 via the slide bar 130.

[0064] In this embodiment, the slide bar 130 is a stepped bar, and the length direction of the slide bar 130 is parallel to the preset direction; the slide groove 241 is a stepped groove, and the extension direction of the slide groove 241 is parallel to the preset direction; the slide bar 130 is embedded in the slide groove 241 and can slide in the slide groove 241 along the preset direction.

[0065] The sliding bar 130 and sliding groove 241 used in conjunction not only reduce the resistance encountered by the pull-out box 200 when sliding on the display body 100, improving the smoothness of the sliding of the pull-out box 200 on the display body 100, but also provide clear guidance for the sliding of the pull-out box 200 on the display body 100. The operator can easily push the pull-out box 200 along the preset direction to make it accurately reach the predetermined position, effectively reducing the difficulty of the sliding operation and improving the efficiency of the sliding operation.

[0066] In addition, to improve the smoothness of the sliding box 200 sliding on the display body 100, there can be multiple sliders 130, and the multiple sliders 130 are spaced apart along a direction perpendicular to the preset direction; the number of slide grooves 241 is the same as the number of sliders 130, and the multiple slide grooves 241 are respectively arranged in correspondence with the multiple sliders 130.

[0067] Referring to Figures 2, 4, 7, 10 and 11, in one embodiment, a slider 130 is disposed on a back plate 110, and a groove 241 is disposed on a pull-out box 200; the length of the slider 130 is less than the length of the groove 241.

[0068] In this embodiment, the slider 130 is fixedly mounted on the back plate 110 using connecting screws; a slide rail 240 is fixedly mounted inside the pull-out box 200 using connecting screws, and a slide groove 241 is provided on the slide rail 240 and faces the back plate 110. In other embodiments, the slider 130 may also be provided on the pull-out box 200, and the slide groove 241 may be provided on the back plate 110.

[0069] On the one hand, with the slide bar 130 located on the back panel 110, the pull-out box 200 can be easily inserted into one end of the slide bar 130 via the slide groove 241 and slide along the slide bar 130 to the predetermined position. This operation is more ergonomic. During installation, it is easier for installers to apply force and control the direction of movement of the pull-out box 200, making the installation process smoother and less strenuous.

[0070] On the other hand, the structural design that the length of the slider 130 is less than the length of the groove 241 allows the pull-out box 200 to have a certain sliding margin during installation. During product design and production, the position of the slider 130 on the back plate 110 can be flexibly adjusted according to actual needs without making significant modifications to the groove 241 on the pull-out box 200, thus improving the flexibility of product design.

[0071] Referring to Figures 2 to 4, in one embodiment, a handle 250 is provided on the surface of the pull-out box 200 near the preset edge 120. The handle 250 improves the ease of sliding the pull-out box 200 on the display body 100.

[0072] Referring to Figures 2, 4, 7 and 10 to 12, in one embodiment, a second limiting member 500 is provided in the slide groove 241; when the pull-out box 200 is in the exposed position, the second limiting member 500 prevents the pull-out box 200 from continuing to move toward the preset edge 120 by contacting the surface of the slide bar 130 away from the preset edge 120.

[0073] In this embodiment, the second limiting member 500 is a limiting block. The second limiting member 500 is located on the side of the slide bar 130 away from the preset edge 120 in a preset direction, and is fixedly installed in the slide groove 241 using connecting screws. In addition, in order to avoid hard contact between the second limiting member 500 and the slide bar 130, thereby extending the service life of the slide bar 130 and the second limiting member 500, the second limiting member 500 is a silicone part or a rubber part.

[0074] The second limiting member 500 serves as a limiter, working in conjunction with the limiting body 410 to further prevent the pull-out box 200 in the exposed position from continuing to move toward the preset edge 120. This prevents the pull-out box 200 from falling off the display body 100 due to accidental collisions, vibrations, or other factors, ensuring the stability and reliability of the installation box in the exposed position on the display body 100.

[0075] Referring to Figures 4, 6, 7, 11 and 13 to 15, in one embodiment, one of the display body 100 and the pull-out box 200 is provided with a guide strip 260, and the other is provided with a guide groove 141. The guide strip 260 passes through the guide groove 141 and can slide in the guide groove 141 in a preset direction.

[0076] In this embodiment, the guide bar 260 and the guide groove 141 are both set along a preset direction. The guide bar 260 and guide groove 141, used in conjunction, not only ensure that the pull-out box 200 moves precisely along the preset direction, avoiding instability such as deviation or wobbling, but also ensure the stability and reliability of the pull-out box 200's movement. Furthermore, due to the clear guidance, the user can pull out the pull-out box 200 more smoothly and naturally, without needing to exert extra force to adjust its position or angle, making operation easier and more convenient, and improving the user experience.

[0077] In addition, to improve the smoothness of the pull-out box 200 movement, there are two guide bars 260, which are spaced apart in a direction perpendicular to the preset direction; the number of guide grooves 141 is the same as the number of guide bars 260, and the two guide bars 260 are respectively set to correspond one-to-one with the two guide grooves 141.

[0078] Referring to Figures 4, 6, 7, 11, and 13 to 15, in one embodiment, a guide strip 260 is provided in the pull-out box 200, a guide rail 140 is provided on the back plate 110, and a guide groove 141 is provided on the guide rail 140; a limiting groove 270 is provided on the side of the pull-out box 200 along a preset direction, the limiting groove 270 has a first limiting groove wall 271 and a second limiting groove wall 272 spaced apart along the preset direction, and the second limiting groove wall 272 is located on the side of the first limiting groove wall 271 away from the preset edge 120.

[0079] The guide rail 140 has a limiting structure 142, which is inserted into the limiting groove 270. It is used to block the pull-out box 200 in the hidden position from moving away from the preset edge 120 by contacting the first limiting groove wall 271, and to block the pull-out box 200 in the exposed position from moving toward the preset edge 120 by contacting the second limiting groove wall 272.

[0080] In this embodiment, the guide strip 260 and the pull-out box 200 are integrally formed to facilitate manufacturing and processing; the guide rail 140 is arranged along a preset direction and fixedly installed on the back plate 110. In other embodiments, the guide strip 260 may also be arranged on the back plate 110, and the guide rail 140 may be arranged on the pull-out box 200. The limiting structure 142 is a limiting plate, which is integrally formed with the guide rail 140 and can maintain a close fit with the first limiting groove wall 271 or the second limiting groove wall 272.

[0081] On the one hand, the guide strip 260 is set on the pull-out box 200, while the guide rail 140 is set on the back plate 110. This structural design not only ensures a relatively stable connection between the pull-out box 200 and the back plate 110 through the guide strip 260 and the guide rail 140, but also allows the pull-out box 200 to better withstand tension and pressure during the pulling process, making it less prone to loosening or deformation and improving the overall structural stability. Furthermore, when installing the pull-out box 200, simply align the guide strip 260 on the pull-out box 200 with the guide groove 141 on the guide rail 140 and insert it. This simple and convenient operation facilitates positioning, improves installation efficiency, reduces installation difficulty, and makes batch installation on the production line easier.

[0082] On the other hand, the limiting structure 142 can precisely stop the pull-out box 200 from continuing to move when it reaches the hidden position or the exposed position, ensuring that the pull-out box 200 can accurately stop at the hidden position or the exposed position every time, avoiding over-pulling or under-pulling. This not only improves the consistency and accuracy of the pulling action, thereby enhancing the stability of the pull-out box 200 during the movement, but also improves the convenience of use and the efficiency of operation.

[0083] Referring to Figures 2, 4, 7, and 11, in one embodiment, the display device further includes an adapter 310, a transmitter card 320, and a WiFi module 330. The adapter 310 is disposed inside the pull-out box 200; the transmitter card 320 is disposed inside the pull-out box 200 and is electrically connected to the adapter 310 via a control unit 300, and is also electrically connected to the display body 100; the WiFi module 330 is disposed in the pull-out box 200 and is electrically connected to the control unit 300.

[0084] In this embodiment, the adapter 310 is fixedly installed inside the pull-out box 200 using connecting screws and is electrically connected to the control component 300; the transmitter card 320 is fixedly installed inside the pull-out box 200 using connecting screws and is electrically connected to the control component 300. WiFi stands for Wireless Fidelity; the main structure of the WiFi module 330 is a WiFi board, which provides wireless access functionality and enables high-speed data transmission and bidirectional data interaction; the WiFi board is installed inside the pull-out box 200 using connecting screws.

[0085] On the one hand, by housing the adapter 310, transmitter card 320, and WiFi module inside the pull-out box 200, a high degree of integration of multiple functions is achieved. This not only transforms the pull-out box 200 into a simple storage space but also into a multi-functional module carrier with signal processing, transmission, and network connectivity capabilities, enriching the overall functionality of the display device. Simultaneously, this structural design facilitates maintenance of each functional component, saving after-sales costs. Furthermore, it makes the entire display device structure more compact, contributing to the miniaturization and thinning of the display device.

[0086] On the other hand, by adopting a WiFi module, the display device no longer needs to be connected to the network via a network cable, avoiding the hassle of wiring and making the placement of the display device more flexible. It is not limited by the length and location of the network cable, and users can place the display device anywhere there is a power outlet according to their actual needs, thus improving space utilization.

[0087] In summary, the display device provided in this embodiment has at least the following beneficial technical effects: On the one hand, by using the pull-out box 200 and control component 300 used in this application, the control component 300 no longer occupies the space inside the lower profile 150. Compared with the method of fixing the control component 300 inside the lower profile 150 of the display body 100, the structural design in this application effectively reduces the width of the lower profile 150, which is conducive to realizing the ultra-narrow bezel design and improving the screen ratio and visual effect of the display device.

[0088] On the other hand, the first limiting member 400 effectively prevents the pull-out box 200 in the hidden position from moving toward the preset edge 120, thus ensuring that the pull-out box 200 can remain stably in the hidden position. This structural design prevents the pull-out box 200 from moving toward the preset edge 120 due to gravity during transportation and installation of the display device, ensuring the stability and reliability of the pull-out box 200 in the hidden position on the display body 100.

[0089] On the other hand, the pull-out box 200 is hidden when not in use, and is covered and protected by the back panel 110. This effectively prevents external dust, moisture, and other impurities from corroding and damaging the functional components such as the control unit 300 on the pull-out box 200, extending the service life of the pull-out box 200 and the control unit 300, and improving the reliability and stability of the entire display device. It also ensures that there are no obtrusive exposed components, keeping the overall appearance of the display device simple and flat, thus enhancing its aesthetics.

[0090] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. It should be noted that, for those skilled in the art, several equivalent obvious modifications and / or equivalent substitutions can be made without departing from the technical principles of this application, and these obvious modifications and / or equivalent substitutions should also be considered within the scope of protection of this application.
