Detailed Implementation

[0043] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "connected" to another element, it can be directly on the other element, or one or more intermediate elements can exist between them. The terms "upper," "lower," "left," "right," "upper end," "lower end," "top," and "bottom," etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0045] In related technologies, most telescopic wall-mounted devices adopt a manual structure, requiring users to manually push or pull the large screen to achieve telescopic adjustment, which is very inconvenient to use.

[0046] Please refer to the following: Figure 1 and Figure 2 In order to solve the above-mentioned technical problems, this application provides a wall-mounted device 100, which is applied to a display system and can mount a display screen and drive the display screen to extend and retract back and forth.

[0047] In some embodiments, the wall-mounted device 100 includes a mounting bracket 10, a wall mount 20, a telescopic mechanism 30, a linear drive 40, and a control element 50. The wall mount 20 is used to mount a display screen. The telescopic mechanism 30 is connected at both ends to the mounting bracket 10 and the wall mount 20, respectively, and is capable of extending and retracting horizontally to support the wall mount 20. The linear drive 40 is connected to both the mounting bracket 10 and the wall mount 20, and is used to drive the wall mount 20 closer to or further away from the mounting bracket 10. The control element 50 can be mounted on either the mounting bracket 10 or the wall mount 20. The control element 50 is electrically connected to the linear drive 40 and is used to control the linear drive 40 to drive the wall mount 20 closer to or further away from the mounting bracket 10 horizontally. The mounting bracket 10 can be fixed to a wall or supported on the ground.

[0048] The working principle of the wall-mounted device 100 in this embodiment is as follows: The wall-mounted device 100 is provided with a telescopic mechanism 30 that connects the mounting bracket 10 and the wall-mounted bracket 20 and enables horizontal extension and retraction. A linear drive member 40 drives the wall-mounted bracket 20 to move horizontally closer to or further away from the mounting bracket 10. A control element 50 can be installed on the mounting bracket 10 or the wall-mounted bracket 20 and controls the movement of the linear drive member 40 via electrical connection. The extension and retraction of the linear drive member 40 drives the entire telescopic mechanism 30 in a coordinated manner, thereby achieving horizontal displacement of the wall-mounted bracket 20.

[0049] Understandably, the wall-mounted device 100 in this embodiment of the application implements an electric telescopic function, replacing the manual operation of the transmission, greatly improving the convenience and comfort of the user. Through electric control, the automatic retraction and unfolding of the display screen can be easily achieved, enhancing the user experience and facilitating daily adjustment and maintenance.

[0050] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the telescopic mechanism 30 includes a first transmission rod 31 and a second transmission rod 32. One end of the first transmission rod 31 is rotatably connected to the mounting frame 10, and the other end of the first transmission rod 31 is rotatably connected to the wall mount 20 and is capable of reciprocating relative to the wall mount 20 in the height direction. One end of the second transmission rod 32 is rotatably connected to the mounting frame 10 and is capable of reciprocating relative to the mounting frame 10 in the height direction.

[0051] The other end of the second transmission rod 32 is rotatably connected to the wall mount 20, and the second transmission rod 32 and the first transmission rod 31 are arranged to cross each other and are rotatably connected at the intersection point.

[0052] Understandably, the telescopic mechanism 30 consists of a first transmission rod 31 and a second transmission rod 32 forming a cross-shaped X-link structure. This cross-shaped X-link structure converts vertical sliding and rotational motion of the rods into horizontal telescopic movement, ensuring that the wall mount 20 remains stable and level during horizontal telescopic movement, preventing tilting or swaying, and thus guaranteeing stable installation and safe operation of the display screen.

[0053] Please refer to the following: Figure 3 , Figure 4 and Figure 5In some embodiments, the telescopic mechanism 30 further includes a first rotating shaft 331, a second rotating shaft 332, a first bushing 333, and a second bushing 334. The mounting bracket 10 is provided with a first through hole 11, and one end of the first transmission rod 31 is provided with a second through hole 311 that is aligned with the first through hole 11. The first rotating shaft 331 passes through the first through hole 11 and the second through hole 311 respectively, and the first bushing 333 is sleeved on the first rotating shaft 331 and is at least partially received in the first through hole 11 and / or the second through hole 311.

[0054] Optionally, the number of first bushings 333 can be single or two. When two first bushings 333 are used, the two first bushings 333 are simultaneously fitted onto the first rotating shaft 331 and respectively abut against the two opposite end faces of the second through hole 311. In some embodiments, the first rotating shaft 331 is made of mutually mating bolts and nuts to prevent the first transmission rod 31 and the mounting bracket 10 from disengaging from each other. In other embodiments, the first rotating shaft 331 can also be a rivet or the like.

[0055] The wall mount 20 is provided with a third through hole 21, and the other end of the second transmission rod 32 is provided with a fourth through hole 321 that is aligned with the third through hole 21. The second rotating shaft 332 passes through the third through hole 21 and the fourth through hole 321 respectively. The second bushing 334 is sleeved on the second rotating shaft 332 and partially housed in the third through hole 21 and / or the fourth through hole 321.

[0056] Optionally, the number of second bushings 334 can be single or two. When two second bushings 334 are used, both second bushings 334 are simultaneously fitted onto the second rotating shaft 332 and respectively abut against the two opposite end faces of the fourth through hole 321. In some embodiments, the second rotating shaft 332 uses mutually mating bolts and nuts to prevent the second transmission rod 32 and the wall mount 20 from disengaging from each other. In other embodiments, the second rotating shaft 332 can also be a rivet or the like.

[0057] Understandably, in this embodiment of the application, by setting a first bushing 333 and a second bushing 334 to respectively cover the first rotating shaft 331 and the second rotating shaft 332, the direct rotational friction between the first rotating shaft 331 and the mounting bracket 10 and between the second rotating shaft 332 and the wall-mounted bracket 20 is transformed into low-resistance sliding between the rotating shaft and the bushing.

[0058] Furthermore, the bushing improves the coaxiality of the shaft and its connecting components. For example, when the first bushing 333 is installed into the through hole between the mounting bracket 10 and the transmission rod, it can compensate for minor hole position deviations that may occur during the machining of the first through hole 11 and the second through hole 311 in the mounting bracket 10 and the first transmission rod 31. The more precise inner hole of the first bushing 333 constrains the position of the first shaft 331, thereby ensuring that the first transmission rod 31 and the mounting bracket 10 can rotate more around the same central axis, improving the coaxiality and stability of the connection. The bushing is usually made of wear-resistant and self-lubricating material, which not only makes the movement of the telescopic mechanism 30 smoother and quieter, but also effectively absorbs wear and protects the shaft.

[0059] Please refer to the following: Figure 3 and Figure 6 In some embodiments, the telescopic mechanism 30 further includes a third rotating shaft 341 and a partition 342. The first transmission rod 31 is provided with a fifth through hole 312, which is located at the intersection of the first transmission rod 31 and the second transmission rod 32. The second transmission rod 32 is provided with a sixth through hole 322 that is aligned with the fifth through hole 312. The third rotating shaft 341 passes through the fifth through hole 312 and the sixth through hole 322 respectively. The partition 342 is sleeved on the third rotating shaft 341 and located between the first transmission rod 31 and the second transmission rod 32.

[0060] Understandably, the third rotating shaft 341 passes through the fifth through hole 312 of the first transmission rod 31 and the sixth through hole 322 of the second transmission rod 32, with the first partition 342 positioned between the two transmission rods. The first partition 342 maintains the gap between the first transmission rod 31 and the second transmission rod 32, effectively preventing direct friction or jamming between the two transmission rods during cross-rotation, thus ensuring the smooth movement of the X-type linkage structure.

[0061] In some embodiments, the telescopic mechanism 30 further includes a third bushing 343 sleeved on the third rotating shaft 341, the third bushing 343 being at least partially received within the fifth through hole 312 and / or the sixth through hole 322. The number of third bushings 343 can be set according to actual needs. For example, each of the fifth through hole 312 and the sixth through hole 322 is connected to a corresponding third bushing 343. In some embodiments, the third rotating shaft 341 uses mutually cooperating bolts and nuts to prevent the first transmission rod 31 and the second transmission rod 32 from disengaging from each other. In other embodiments, the third rotating shaft 341 can also be a rivet or the like.

[0062] Please refer to the following: Figure 3 , Figure 7 and Figure 8 In some embodiments, the telescopic mechanism 30 further includes a fourth pivot 351, a fifth pivot 352, a first limiting piece 353, a second limiting piece 354, a third limiting piece 355, and a fourth limiting piece 356.

[0063] The mounting bracket 10 has a first sliding groove 12. One end of the second transmission rod 32 has a seventh through hole 323 that aligns with the first sliding groove 12. A fourth rotating shaft 351 passes through the first sliding groove 12 and the seventh through hole 323. A first limiting piece 353 and a second limiting piece 354 are respectively fitted onto the fourth rotating shaft 351 and are respectively located on both sides of the first sliding groove 12. The wall mount 20 has a second sliding groove 22. The other end of the first transmission rod 31 has an eighth through hole 313 that aligns with the second sliding groove 22. A fifth rotating shaft 352 passes through the second sliding groove 22 and the eighth through hole 313. A third limiting piece 355 and a fourth limiting piece 356 are respectively fitted onto the fifth rotating shaft 352 and are respectively located on both sides of the second sliding groove 22.

[0064] Understandably, by setting the first slide groove 12 and the second slide groove 22 on the mounting bracket 10 and the wall mount 20 respectively, and allowing the ends of the second transmission rod 32 and the first transmission rod 31 to slide within the corresponding slide grooves via the fourth rotating shaft 351 and the fifth rotating shaft 352 respectively, the telescopic mechanism 30 can be extended and retracted. The telescopic mechanism 30 also includes a first limiting piece 353 and a second limiting piece 354 respectively disposed on both sides of the first slide groove 12, and a third limiting piece 355 and a fourth limiting piece 356 respectively disposed on both sides of the second slide groove 22. The cooperation between the limiting pieces ensures the stability and safety of the entire telescopic mechanism 30 during movement. Specifically, when the telescopic mechanism 30 extends or retracts, the fourth rotating shaft 351 and the fifth rotating shaft 352 move within their respective slides. The limiting plates on both sides of the slides restrict the movement of the corresponding rotating shafts to the length direction of the slides, effectively preventing the fourth rotating shaft 351 and the fifth rotating shaft 352 from disengaging from their respective slides or deflecting within the slides. This avoids the risk of the wall mount 20 and the mounting bracket 10 tilting, shaking, or even falling due to the ends of the first transmission rod 31 and the second transmission rod 32 disengaging from their respective slides or their movement direction deflecting from the length direction of the slides, thus ensuring the stability and safety of the display screen mounting.

[0065] In some embodiments, the first limiting piece 353 or the second limiting piece 354 is partially received in the first slide groove 12 and slides in cooperation with the first slide groove 12; the third limiting piece 355 or the fourth limiting piece 356 is partially received in the second slide groove 22 and slides in cooperation with the second slide groove 22. This embodiment of the application uses the partial structure of the limiting piece sliding in cooperation with the corresponding slide groove to replace the relative sliding between the rotating shaft and the slide groove, thereby reducing wear on the rotating shaft.

[0066] In some embodiments, the telescopic mechanism 30 further includes a fourth bushing 357 sleeved on the fourth rotating shaft 351 and a fifth bushing 358 sleeved on the fifth rotating shaft 352. The fourth bushing 357 is at least partially received within the seventh through hole 323, and the fifth bushing 358 is at least partially received within the eighth through hole 313. The number of fourth bushings 357 and fifth bushings 358 can be set according to actual needs. In some embodiments, the fourth rotating shaft 351 uses a bolt and nut that cooperate with each other to prevent the second transmission rod 32 and the mounting bracket 10 from disengaging. In other embodiments, the fourth rotating shaft 351 can also be a rivet or the like. Correspondingly, in some embodiments, the fifth rotating shaft 352 includes a bolt and nut that cooperate with each other to prevent the first transmission rod 31 and the wall mount 20 from disengaging. In other embodiments, the fifth rotating shaft 352 can also be a rivet or the like.

[0067] In some embodiments, the wall mount 20 is connected to a corresponding linear drive member 40 at at least one end in the length direction; and / or the wall mount 20 is connected to a corresponding linear drive member 40 at the middle part in the length direction.

[0068] Understandably, by providing corresponding linear drive members 40 at at least one end and / or the middle of the wall mount 20 along its length, the drive points can be flexibly configured according to the size and weight of the display screen, enhancing stability and smoothness during the extension and retraction process. This ensures that even wider or heavier display screens can achieve smooth and synchronous extension and retraction, thereby improving the load-bearing capacity and applicability of the entire wall mount device 100. In one embodiment, corresponding linear drive members 40 are provided at both ends of the wall mount 20 along its length to avoid uneven force distribution during unilateral drive, which could lead to instability in the movement of the wall mount 20. In another embodiment, a linear drive member 40 is provided in the middle of the wall mount 20 along its length, making it easy to conceal the linear drive member 40 under the obstruction of the display screen and maintaining consistent movement. In other embodiments, linear drive members 40 are provided at both ends and the middle of the wall mount 20 along its length to further improve the movement stability of the wall mount 20.

[0069] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the wall mount 20 includes a connector 23, and the linear drive 40 includes a fixed end 41 and a telescopic end 42. The fixed end 41 is rotatably connected to the mounting bracket 10. The telescopic end 42 is rotatably connected to the connector 23, and the telescopic end 42 is movable relative to the fixed end 41 along the telescopic direction of the linear drive 40.

[0070] As is understandable, the linear drive component 40 consists of a fixed end 41 and a telescopic end 42. The fixed end 41 is rotatably connected to the mounting bracket 10, and the telescopic end 42 is rotatably connected to the wall mount 20 via the connector 23. When the linear drive component 40 extends or retracts, it drives the telescopic end 42 to move relative to the fixed end 41, thereby driving the wall mount 20 to move. This ensures that the linear drive component 40 can directly and effectively apply push and pull forces to the wall mount 20 during the extension and retraction process.

[0071] Optionally, the linear drive 40 can be an electric actuator, an electric cylinder, a pneumatic cylinder, or a linear motor, etc. In some embodiments, the linear drive 40 is an electric actuator, which includes a body and a rod structure. The rod structure is partially housed in the body. When the electric actuator is working, the body drives the rod structure to extend or retract. The fixed end 41 and the telescopic end 42 are located at two ends of the electric actuator, respectively. The fixed end 41 is a part of the structure on the body, and the telescopic end 42 is a part of the structure on the rod structure.

[0072] In some embodiments, the linear drive member 40 is inclined relative to the horizontal plane, and the height of the fixed end 41 is higher than the height of the telescopic end 42.

[0073] Understandably, the direction in which the fixed end 41 of the linear drive 40 points towards the telescopic end 42 is tilted towards the display screen, meaning the linear drive 40 is installed at a specific tilt angle relative to the horizontal plane. Within the limited stroke of the linear drive 40, better driving torque can be provided in a specific telescopic state. Furthermore, a reasonable tilt angle helps improve structural compactness, allowing it to be closer to the wall in the retracted state, reducing overall space occupation and making the wall-mounted device 100 more aesthetically pleasing.

[0074] In some embodiments, each end of the wall mount 20 in the length direction is connected to a corresponding telescopic mechanism 30, and at least one end of the wall mount 20 in the length direction is connected to a corresponding linear drive member 40. The mounting bracket 10 includes a fixing member 13, which is further away from the wall mount 20 than the telescopic mechanism 30 in the length direction of the wall mount 20. The fixing end 41 is rotatably connected to the fixing member 13, and the connecting member 23 extends in the length direction of the wall mount 20 and avoids the telescopic mechanism 30.

[0075] Understandably, this embodiment of the application provides two telescopic mechanisms 30 to support both ends of the wall mount 20, significantly enhancing the stability and load-bearing capacity during the telescopic process, making it particularly suitable for large displays. Furthermore, the linear drive member 40 is connected to the end of the wall mount 20 along its length. The fixing member 13 is further away from the wall mount 20 along its length than the telescopic mechanism 30. The connecting member 23 extends along the length of the wall mount 20, avoiding the telescopic mechanism 30. That is, by placing the fixing member 13 and the connecting member 23 at the edge of the overall structure, the linear drive member 40 avoids the telescopic mechanism 30, ensuring that maintenance and replacement are not obstructed by other structures, facilitating maintenance and replacement operations.

[0076] In some embodiments, the control element 50 includes a housing, a circuit board, a wireless module, and control buttons. The circuit board and the wireless module are installed inside the housing, and the control buttons are installed on the surface of the housing. The circuit board is electrically connected to the linear drive 40, the wireless module, and the control buttons, respectively. The circuit board is used to control the linear drive 40 to drive the wall mount 20 according to the received signal from the wireless module or the trigger signal from the control button.

[0077] In practical use, users can send control signals to the control element 50 via remote control, mobile terminal, etc., so that the control element 50 controls the linear drive 40 to drive the display screen to move horizontally. When the display screen is not mounted, the linear drive 40 can be controlled via the control buttons on the control element 50 to move the wall mount 20 horizontally, which is convenient for debugging and operation.

[0078] In some embodiments, the control element 50 is mounted on the wall mount 20 and located behind the display screen. When the wall mount 20 is retracted, it still maintains a certain distance from the rear wall and allows the user to reach out from the side to trigger the control button of the control element 50, so that the horizontal extension and retraction of the display screen can be controlled even when there is no remote control, mobile terminal or other device.
