Description

Technical Field

[0001] This application belongs to the field of wall mount technology, and more specifically, relates to a television wall mount. Background Technology

[0002] Currently, the conventional tilt angle adjustment structure of TV wall mounts is as follows: Figure 1 As shown, it mainly includes a rotating shaft 1, an adjusting handle 2, a connecting piece 3, and a locking nut 4. The connecting piece 3 is provided with a waist-shaped hole, and the adjusting handle 2 and the locking nut 4 are respectively connected to two waist-shaped holes 301.

[0003] The adjustment process and principle of the TV wall mount tilt angle structure are as follows: After the TV is installed on the wall mount that is locked with the connector 3, first adjust the preload between the locking nut 4 and the waist-shaped hole 301 so that the TV can be easily moved by hand to adjust its tilt angle. Finally, tighten the adjustment handle 2 to secure it.

[0004] However, the preload between the locking nut 4 and the oblong hole 301 in this structure is not easy to control. If the preload is too large, a lot of force is needed to turn the TV when adjusting the tilt angle, or the TV may not be able to be turned at all. If the preload is too small, tightening the adjusting handle 2 alone cannot provide the friction required to lock the TV. Therefore, the operation is not very convenient and requires a high level of skill. Utility Model Content

[0015] In one optional embodiment, the telescopic rotating frame includes two first horizontal bars and two second horizontal bars. One end of each of the two first horizontal bars is rotatably connected to the base, and the other end of each of the two first horizontal bars is rotatably connected to one end of each of the two second horizontal bars. The other end of each of the two second horizontal bars is rotatably connected to one side of the wall panel.

[0016] The beneficial effects of the TV wall mount provided in this application are as follows: Compared with the prior art, the TV wall mount of this application embodiment rotatably connects the swing frame to the base, one side of the swing block is fixedly connected to the swing frame, and the sliding part of the middle block extends into the first slide rail of the swing block, the first slide rail being inclined; in use, the middle block is driven to move up and down by the drive structure, so that the middle block moves relative to the base, the sliding part moves in the first slide rail of the swing block, and drives the swing block to drive the swing frame to rotate relative to the base, that is, to drive the TV mounted on the swing frame to rotate, thereby realizing the function of adjusting the TV tilt angle; since it is not necessary to manually adjust the locking nut to change the preload, the angle adjustment can be completed simply by controlling the drive structure to drive the middle block to move, which is convenient to operate and can easily adjust the tilt angle of the TV, which not only improves convenience, but also avoids direct contact with the TV screen and reduces the TV damage that may be caused by misoperation.

Detailed Implementation

[0030] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0031] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0032] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They 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. Therefore, they should not be construed as limitations on this application.

[0033] 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 that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0034] Currently, the conventional tilt angle adjustment structure of TV wall mounts is as follows: Figure 1 As shown, the core components include a rotating shaft 1, an adjusting handle 2, a connecting piece 3, and a locking nut 4. The connecting piece 3 is provided with a slotted hole 301, and the adjusting handle 2 and the locking nut 4 are respectively connected to two slotted holes 301.

[0035] The adjustment process and principle of the TV wall mount's tilt angle structure are as follows: After installing the TV on the wall mount that is locked to the connector 3, first adjust the preload between the locking nut 4 and the slotted hole 301 so that the torque generated by the frictional force relative to the axis of rotation 1 is approximately equal to the torque of the sum of the weights of the TV and the wall mount relative to the axis of rotation 1. Once this condition is met, the TV can be easily adjusted by hand to change its tilt angle. Finally, tighten the adjustment handle 2 to secure it. When the TV tilt angle needs to be adjusted again, simply loosen the adjustment handle 2 manually, move the TV to the appropriate angle, and tighten the adjustment handle 2 again.

[0036] pass Figure 1 As can be seen from its adjustment principle, the conventional TV mount tilt angle adjustment structure only requires adjusting the preload between the locking nut 4 and the oblong hole 301 during initial use. Subsequent adjustments only require adjusting the control handle 2. However, the structure has the following drawbacks: First, the preload between the locking nut 4 and the oblong hole 301 is difficult to control. If the preload is too large, a lot of force is required to turn the TV when adjusting the tilt angle, or the TV may not be able to be turned at all. If an ultra-thin TV is installed, this forced operation may even damage the TV. If the preload is too small, it can only be adjusted manually. First, the tightening handle 2 cannot provide the friction required to lock the TV securely. Second, after multiple adjustments, the locking nut 4 may loosen, and the contact surface between the locking nut 4 and the oblong hole 301 will wear down due to repeated friction, resulting in a decrease in friction. In this case, a wrench is needed to readjust the locking nut 4, which is quite troublesome. Finally, during the entire process of adjusting the TV's tilt angle, in order to prevent the TV from suddenly flipping and falling to the lowest point, it is necessary to hold the TV steady with one hand and operate the adjusting handle 2 with the other hand at all times. This requires a high level of skill from the user, and operational errors may damage the TV.

[0037] Please refer to the following: Figures 2 to 9The TV wall mount 100 provided in this application embodiment will now be described. The TV wall mount 100 includes: a base 20; a swing frame 10, one end of which is rotatably connected to the base 20 and is used to connect a TV; a middle block 40, on which a sliding part 41 is protruding; and a swing block 50, one side of which is fixedly connected to the swing frame 10 and has a first slide rail 51, the sliding part 41 extending into the first slide rail 51; and a drive structure (not shown in the figure) for driving the middle block 40 to move up and down, thereby causing the sliding part 41 to move in the first slide rail 51, and thereby causing the swing block 50 and the swing frame 10 to rotate relative to the base 20.

[0038] The base 20 is used to install and fix components, and the swing bracket 10 is used to mount the television. The swing bracket 10 is rotatably connected to the base 20 and can rotate relative to the base 20, thus allowing the television to rotate and its tilt angle to be adjusted. The base 20 can be connected to a wall or placed horizontally using a bracket. The swing bracket 10 can be directly connected to the television or connected to the television using an additional connection structure. Furthermore, the television mount 100 can also be used to mount other displays. The swing bracket 10 is rotatably connected to the base 20 via a pivot or a hinge. The specific connection positions between the swing bracket 10 and the base 20 can be: the middle of the swing bracket 10 is rotatably connected to the middle of the base 20; one side of the swing bracket 10 is rotatably connected to one side of the base 20; or one end of the swing bracket 10 is rotatably connected to one end of the base 20.

[0039] The sliding part 41 can protrude from the intermediate block 40, or a slot can be cut into the intermediate block 40, with the portion between two slots forming the sliding part 41, etc. By providing a driving structure, the intermediate block 40 is connected to the driving end of the driving structure, which drives the intermediate block 40 to move up and down, allowing the intermediate block 40 to move relative to the base 20. The driving structure can be a lead screw, a hydraulic cylinder, or an oil cylinder, or it can be a gear and rack mechanism, etc.

[0040] The sliding part 41 on the intermediate block 40 is used to extend into the first slide rail 51 of the swing block 50. When the drive structure drives the intermediate block 40 to move relative to the base 20, the sliding part 41 moves along the first slide rail 51.

[0041] The sliding part 41 moves in the first slide rail 51, which is inclined, so it can drive the swing block 50 to rotate relative to the base 20. One side of the swing block 50 is fixedly connected to the swing frame 10, so it can further drive the swing frame 10 to rotate relative to the base 20, thereby driving the TV mounted on the swing frame 10 to rotate and adjust the tilt angle of the TV.

[0042] Specifically, the first slide rail 51 can be tilted vertically or horizontally. When the first slide rail 51 is tilted vertically, driving the intermediate block 40 to move up and down vertically adjusts the angle of the swing frame 10 in the vertical direction, thus adjusting the tilt angle of the television. When the first slide rail 51 is tilted horizontally, driving the intermediate block 40 to move up and down horizontally adjusts the angle of the swing frame 10 in the horizontal direction, thus adjusting the horizontal angle of the television.

[0043] Since it does not require manual adjustment of the locking nut to change the preload, it is more convenient to use. The angle can be easily adjusted by simply moving the middle block 40 through the drive structure, which solves the operational problem caused by the inconvenience of controlling the preload in conventional structures.

[0044] The TV angle can be easily adjusted by controlling the drive mechanism without direct contact with the television. By reducing complex preload adjustment steps, the initial installation process is simplified, eliminating the need for users to spend considerable time fine-tuning the optimal preload and improving overall installation efficiency. This not only enhances user convenience but also avoids direct contact with the TV screen, reducing potential damage from misoperation and lowering the risk of accidental displacement or even drop. Since no forceful manipulation of the TV itself is required for angle adjustment, the entire mechanism is more stable and reliable.

[0045] Compared with the prior art, the TV wall mount 100 provided in this application rotatably connects the swing frame 10 to the base 20, fixes one side of the swing block 50 to the swing frame 10, and extends the sliding part 41 of the middle block 40 into the first slide rail 51 of the swing block 50, which is inclined. In use, the middle block 40 is driven to move up and down by the drive structure, so that the middle block 40 moves relative to the base 20. The sliding part 41 moves in the first slide rail 51 of the swing block 50, driving the swing block 50 to drive the swing frame 10 to rotate relative to the base 20, that is, to drive the TV mounted on the swing frame 10 to rotate, thereby realizing the function of adjusting the TV tilt angle. Since it is not necessary to manually adjust the locking nut to change the preload, the angle adjustment can be completed simply by controlling the drive structure to drive the middle block 40 to move. The operation is convenient and the tilt angle of the TV can be easily adjusted. This not only improves convenience, but also avoids direct contact with the TV screen and reduces the possibility of TV damage caused by misoperation.

[0046] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 5 to 9 The first slide rail 51 is inclined relative to the vertical direction.

[0047] Vertical direction refers to Figure 6The arrow indicates the up and down direction. The first slide rail 51 is tilted relative to the vertical direction. When the drive block 40 moves up and down, it can drive the swing block 50 and the swing frame 10 to rotate relative to the base 20, thereby adjusting the angle of the swing frame 10 in the vertical direction and thus realizing the adjustment of the TV tilt angle.

[0048] Without directly touching the TV, the tilt angle can be easily adjusted by controlling the drive structure. By controlling the movement distance of the middle block 40, the tilt angle can be precisely controlled. The adjustment is completed by the internal mechanical structure, so users do not need to push or pull the TV screen or body, effectively avoiding scratches or bumps caused by accidental operation.

[0049] In another embodiment of this application, the drive structure includes a lead screw 30, which is rotatably connected to the base 20, and an intermediate block 40 is threadedly connected to the lead screw 30; the angle between the lead screw 30 and the vertical direction is α, and the angle between the first slide rail 51 and the vertical direction is β, where 0 ≤ α < β.

[0050] The angle between the first slide 51 and the vertical direction is β, as shown below. Figures 3 to 9 The driving mechanism includes a lead screw 30, which is rotatably connected to the base 20. The angle between the lead screw 30 and the vertical direction is α, where α satisfies the condition 0 ≤ α < β. That is, the axis of the lead screw 30 can be parallel to the vertical direction or inclined relative to it. When the axis of the lead screw 30 is inclined relative to the vertical direction, the angle between the lead screw 30 and the vertical direction is less than the angle between the first slide rail 51 and the vertical direction. Therefore, the rotation of the lead screw 30 can drive the intermediate block 40 to move, thereby driving the swing block 50 and the swing frame 10 to rotate relative to the base 20.

[0051] The intermediate block 40 is threaded onto the lead screw 30, thus allowing the intermediate block 40 to move along the lead screw 30. The lead screw 30 can be rotated manually using a handle or driven by a mechanism such as a motor. The cooperation between the lead screw 30, the intermediate block 40, and the swing block 50 makes the entire hanger structure more compact.

[0052] In one embodiment, the lead screw 30 is rotatably connected to the base 20 via a bearing, and the lead screw 30 rotates about its own axis without axial displacement relative to the base 20. The intermediate block 40 is threaded to the outside of the lead screw 30, so that the intermediate block 40 can move relative to the base 20 when the lead screw 30 is rotated. In other embodiments, the lead screw 30 is threaded to the base 20, and the intermediate block 40 is connected to the outside of the lead screw 30. When the lead screw 30 is rotated, the lead screw 30 moves axially relative to the base 20, but the intermediate block 40 does not rotate with the lead screw 30, thus allowing the intermediate block 40 to move relative to the base 20.

[0053] like Figure 6 The working principle is as follows: when the middle block 40 moves upward relative to the base 20, Figure 6 As shown in the right triangle ABC, the lengths of lines AC and BC decrease. Since the length of line BC can only decrease along the axis of lead screw 30, the angle θ between lines AC and BC will gradually increase. Similarly, when the middle block 40 moves downward relative to the base 20, θ gradually decreases, thereby realizing the function of adjusting the TV tilt angle.

[0054] In one embodiment, such as Figure 8 and Figure 9 , is the limit angle of rotation of the swing frame 10 relative to the base 20.

[0055] Furthermore, when the lead screw 30 stops rotating, the intermediate block 40 will not move on its own due to the meshing effect between the threads; that is, the above mechanism has a self-locking hovering capability, without the need for an additional locking mechanism, and has the advantages of safety, reliability and ease of use.

[0056] The tilt angle of the TV can be easily adjusted simply by controlling the rotation of the lead screw 30 without directly touching the TV. By designing a lead screw 30 specifically for angle adjustment, users can directly apply this control point to adjust the TV angle without directly touching the TV screen or its frame.

[0057] In another embodiment of this application, please refer to Figure 4 and Figure 5 The drive structure also includes a first bearing 31, the outer ring of which is fixedly connected to the base 20, and the lead screw 30 extends into the inner ring of the first bearing 31 and is fixedly connected to the inner ring of the first bearing 31.

[0058] The lead screw 30 is rotatably connected to the base 20 via the first bearing 31. The lead screw 30 rotates around its own axis and has no axial displacement relative to the base 20. The intermediate block 40 is threaded to the outside of the lead screw 30. Therefore, rotating the lead screw 30 allows the intermediate block 40 to move relative to the base 20, causing the sliding part 41 to move along the first slide rail 51, thereby driving the swing block 50 and the swing frame 10 to rotate, thus adjusting the tilt angle of the television.

[0059] In some embodiments, the drive structure further includes a second bearing 33. The first bearing 31 and the second bearing 33 are respectively disposed on the base 20 along the height direction of the base 20. The lead screw 30 extends into the first bearing 31 and the second bearing 33 in sequence and is fixedly connected to the inner ring of the first bearing 31 and the inner ring of the second bearing 33, thereby enhancing the radial and axial support of the lead screw 30, reducing vibration and offset during operation, and improving stability.

[0060] In other embodiments, such as Figure 3 and Figure 4The base 20 has a top wall and a bottom wall, forming an installation space 25 between them. The swing block 50 is located within the installation space 25. The two ends of the lead screw 30 are respectively mounted on the bottom wall and the top wall of the installation space 25 via a first bearing 31 and a second bearing 33. By forming the installation space 25 inside the base 20, the lead screw 30, the intermediate block 40, and the swing block 50 can all be integrated within the installation space 25, effectively reducing the overall volume of the structure. The rear wall of the installation space 25 near the swing frame 10 and the front wall away from the swing frame 10 are both open, allowing the two swing blocks 50 to be fixedly connected to the swing frame 10 through the openings; at the same time, the openings facilitate the installation of structures such as the lead screw 30 and the intermediate block 40. This design saves installation space 25, avoids exposed mechanical structures, and improves the overall aesthetics of the TV wall mount 100.

[0061] In addition, a first copper sleeve 32 and a second copper sleeve 34 are also provided, such as Figure 4 and Figure 5 First, insert the lead screw 30 into the first bearing 31 and the first copper sleeve 32, then insert the entire screw into the bottom wall of the installation space 25. Screw the intermediate block 40 onto the lead screw 30 through the opening of the installation space 25, then insert the lead screw 30 out through the top wall of the installation space 25. Finally, insert the second bearing 33 and the second copper sleeve 34 into the lead screw 30 and tighten it with screws to complete the installation.

[0062] By using bearings at both ends of the lead screw 30, smooth rotation of the lead screw 30 can be ensured, thereby reducing the force required to adjust the TV tilt angle and making operation easier. Both ends of the lead screw 30 are fixed to the bottom and top walls of the mounting space 25 by bearings and copper sleeves, forming a stable support structure to ensure that the lead screw 30 will not shift or wobble during rotation.

[0063] The copper bushing, as a wear-resistant material, works in conjunction with the bearing to effectively protect the contact surfaces of the lead screw 30 and the base 20, preventing excessive wear due to long-term use and thus extending the service life of the entire TV wall mount 100. The intermediate block 40 is threaded onto the lead screw 30, so simply rotating the lead screw 30 is enough to move the intermediate block 40, thereby adjusting the TV tilt angle, making operation convenient.

[0064] In another embodiment of this application, please refer to Figure 3 One end of the lead screw 30 extends out of the base 20. The TV wall mount 100 also includes an adjustment knob 81, which is fixedly connected to the end of the lead screw 30 located outside the base 20.

[0065] By setting an adjustment knob 81 at the end of the lead screw 30 that extends out of the base 20, the user can directly adjust the tilt angle of the TV by rotating the knob, allowing the user to easily complete the angle adjustment with one hand without additional tools or complicated steps.

[0066] Since the adjustment knob 81 is located outside the base 20, the user can make adjustments without touching or opening the inside of the base 20, thereby reducing the risk of damage to internal components due to misoperation or improper contact.

[0067] The adjusting knob 81 is fixedly connected to the lead screw 30, ensuring that each rotation can be accurately converted into the position movement of the intermediate block 40, thereby controlling the angle of the swing frame 10.

[0068] In one embodiment, such as Figure 4 During installation, first assemble the adjusting knob 81 and the lead screw 30, and then insert the first bearing 31 and the first copper sleeve 32 through the hole below the base 20 (i.e., the hole on the bottom wall of the installation space 25).

[0069] In another embodiment of this application, see [reference] Figure 3 and Figure 4 The TV wall mount 100 also includes a front cover 70, which is connected to the base 20 and covers the side of the mounting space 25 opposite to the swing bracket 10.

[0070] The front cover 70 prevents dust and other contaminants from entering the installation space 25, protecting critical mechanical components (such as the lead screw 30, bearings, and bushings) from external environmental influences and extending their service life. Simultaneously, by shielding the installation space 25, the front cover 70 provides a barrier for the internal components, reducing potential damage from external impacts or human error. It also makes the bracket more aesthetically pleasing, concealing the complex internal mechanical structure and enhancing overall appearance. Furthermore, the front cover 70 prevents users from directly contacting the rotating lead screw 30 or other moving parts, reducing the risk of pinching or other types of injury during use.

[0071] like Figure 4 The front cover 70 is fastened to the base 20 by screws on both sides, making the front cover 70 easy to remove. When adjustment or maintenance is needed, the front cover 70 can be removed to access the internal parts. In addition, the combination of the front cover 70 and the base 20 enhances the overall integrity of the bracket, helps to distribute external forces, and improves the safety and stability of the structure.

[0072] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 4 to 5 The swing frame 10 has a first opening 11 and an arc-shaped hole 12. The base 20 has a first connecting hole 21 corresponding to the first opening 11 and a second connecting hole 22 corresponding to the arc-shaped hole 12. The first opening 11 and the first connecting hole 21 are inserted through the first rotating shaft 13, and the arc-shaped hole 12 and the second connecting hole 22 are inserted through the second rotating shaft 14.

[0073] By providing a first opening 11 and an arc-shaped hole 12 on the swing frame 10, the swing frame 10 can rotate around the first rotating shaft 13, providing a stable support point for the structure. Simultaneously, when the swing frame 10 rotates, the second rotating shaft 14 moves relative to it within the arc-shaped hole 12. The swing frame 10's rotation stroke is limited by the cooperation between the second rotating shaft 14 and the arc-shaped hole 12. The arc-shaped hole 12 restricts the rotation angle of the swing frame 10. Specifically, the center of the arc-shaped hole 12 coincides with the first opening 11.

[0074] like Figure 8 and Figure 9 The engagement of the arc-shaped hole 12 with the second rotating shaft 14 not only provides additional support but also limits the maximum rotation range of the swing frame 10. The arc-shaped hole 12 restricts the rotational stroke of the swing frame 10 at both ends, effectively preventing accidental sliding or tipping of the television during normal use, further enhancing system safety. No matter how the user adjusts the television angle, it will not exceed the preset safety limits, thus avoiding equipment damage or safety hazards caused by excessive tilting.

[0075] The structure of the first rotating shaft 13 can be designed as a rotating shaft or a screw, etc. The structure of the second rotating shaft 14 can be designed as a limit rod or a screw, etc. In addition, washers, nuts, and other structures can be provided for auxiliary connection or limiting.

[0076] When in use, the middle block 40 moves, driving the swing block 50 to cause the swing frame 10 to swing relative to the base 20 around the first rotating shaft 13.

[0077] In another embodiment of this application, the TV wall mount 100 further includes a friction reducing plate 60, which is disposed between the base 20 and the swing frame 10. The friction reducing plate 60 is provided with through holes 62 for the first rotating shaft 13 and the second rotating shaft 14 to pass through respectively.

[0078] The friction-reducing plate 60 is located between the base 20 and the swing frame 10. As a buffer layer, the friction-reducing plate 60 can prevent direct contact and friction between the base 20 and the swing frame 10, thereby avoiding surface scratches or wear caused by long-term use. It can effectively reduce the friction generated between the two during relative movement, extend the service life of each component, and ensure smooth operation.

[0079] The friction-reducing plate 60 can be connected to the base 20 by bonding or welding, making the connection more stable. The friction-reducing plate 60 is provided with a through hole 62, allowing the first rotating shaft 13 and the second rotating shaft 14 to pass through directly.

[0080] In another embodiment of this application, please refer to Figure 4 The grinding plate 60 has a protruding positioning boss 61, and the base 20 has a positioning hole 23, with the positioning boss 61 extending into the positioning hole 23.

[0081] like Figure 4 The wear-reducing plate 60 is also provided with a positioning boss 61. During installation, the positioning boss 61 of the wear-reducing plate 60 is first inserted into the positioning hole 23 of the base 20 to pre-position the wear-reducing plate 60. Then the swing frame 10 is installed and locked by the first rotating shaft 13 and the second rotating shaft 14, which makes the connection more convenient. At the same time, it helps to accurately align and fix the position of the base 20 and the swing frame 10, ensuring the stability and reliability of the structure and enhancing the connection strength between the base 20 and the swing frame 10.

[0082] See Figure 3 The swing bracket 10 is fitted outside the base 20, and the two sides of the swing bracket 10 are rotatably connected to the two sides of the base 20. The base 20 has a clearance space 24 on the side facing the swing bracket 10 to allow the swing bracket 10 to rotate. By fitting the swing bracket 10 outside the base 20 and rotatably connecting it on both sides, a more stable frame structure can be formed, making the entire bracket more stable when bearing the weight of the TV, reducing the swaying or instability that may be caused by single-point support; and the rotatable connection on both sides provides a more balanced force distribution, which helps to disperse the load, thereby improving the load-bearing capacity of the overall system and enabling it to support heavier TVs.

[0083] An clearance space 24 is provided on the base 20. This clearance space 24 ensures that the swing frame 10 will not be interfered with by other components of the base 20 during rotation, guaranteeing smooth and convenient operation and improving user experience. At the same time, by fitting the swing frame 10 onto the outside of the base 20 and providing the clearance space 24 on the base 20, a more compact design can be achieved while still enabling the swing frame 10 to rotate, which helps save installation space.

[0084] In one embodiment, both sides of the swing frame 10 can be rotatably connected to both sides of the base 20 via the first rotating shaft 13, the second rotating shaft 14 and the wear-reducing plate 60.

[0085] In another embodiment of this application, please refer to Figure 4 The middle block 40 has sliding parts 41 on both sides, and two swing blocks 50 are provided, which are respectively located on both sides of the middle block 40.

[0086] Sliding parts 41 are provided on both sides of the middle block 40, and two swing blocks 50 are located on both sides of the middle block 40 respectively. The two sliding parts 41 extend into the first slide rail 51 on the two swing blocks 50 respectively, which ensures that the force distribution is more uniform, reduces the risk of excessive force on one side, and thus improves the stability and reliability of the structure.

[0087] When the drive structure drives the middle block 40 to move along the height direction, the sliding parts 41 on both sides drive the two swing blocks 50 to move synchronously, thereby stably driving the swing frame 10 to rotate and realize the adjustment of the TV pitch angle. This further enhances the accuracy and stability of the adjustment, effectively avoids angle deviation or shaking caused by uneven force at a single point, and ensures that the TV remains stable throughout the adjustment process without tilting or loosening.

[0088] In another embodiment of this application, please refer to Figure 2 The TV wall mount 100 also includes a front panel 82, a telescopic rotating bracket 83, and a wall panel 84. One end of the swing bracket 10 is fixedly connected to one side of the front panel 82, and the other side of the front panel 82 is used to mount the TV. One end of the telescopic rotating bracket 83 rotates with the base 20, and the other end of the telescopic rotating bracket 83 is rotatably connected to the wall panel 84. The wall panel 84 is used to be fixedly connected to the mounting structure (not shown in the figure).

[0089] The mounting structure can be a wall, column, or other structure that can support the wall panel 84. Connecting the front panel 82 to the television ensures a more stable connection. The wall panel 84 is fixedly connected to the mounting structure, ensuring the bracket is securely mounted. The telescopic rotating bracket 83 allows for both telescopic movement (e.g., adjusting the distance between the television and the wall) and left / right rotation (adjusting the angle), providing greater installation flexibility. The rotatable connection between the telescopic rotating bracket 83, the base 20, and the wall panel 84 can be a hinge connection or a bushing connection.

[0090] The design of the front panel 82, telescopic rotating bracket 83, and wall panel 84 forms a robust overall frame, allowing the entire TV wall mount 100 to distribute the weight of the TV more evenly, enhancing the stability of the overall structure and ensuring that the TV will not easily shake or shift after installation. Furthermore, the front panel 82 not only serves to fix the TV but also allows for additional functions such as cable management, helping to hide and organize wires and maintain a neat appearance.

[0091] The overall structure of the TV wall mount 100 is as follows: Figure 2 As shown, the tilt angle adjustment structure can be installed in the middle section of the TV wall mount 100, that is, between the front panel 82 and the telescopic rotating bracket 83.

[0092] In another embodiment of this application, the telescopic rotating frame 83 includes two first horizontal bars 831 and two second horizontal bars 832. One end of each of the two first horizontal bars 831 is rotatably connected to the base 20, and the other end of each of the two first horizontal bars 831 is rotatably connected to one end of each of the two second horizontal bars 832. The other end of each of the two second horizontal bars 832 is rotatably connected to one side of the wall panel 84.

[0093] like Figure 2 By rotatably connecting the first horizontal rod 831 to the base 20, the user can adjust the TV angle by rotating the TV left or right relative to the first horizontal rod 831. The user can also move the TV horizontally left or right.

[0094] Users can also push the TV towards the wall, at which point the angle between the first horizontal bar 831 and the second horizontal bar 832 gradually decreases; or pull the TV away from the wall, at which point the angle between the first horizontal bar 831 and the second horizontal bar 832 gradually increases; thereby adjusting the distance between the TV and the wall.

[0095] The telescopic rotating bracket 83 allows for flexible adjustment of the TV's position and angle to suit various viewing scenarios. The telescopic function allows the TV to be placed close to the wall when not in use, reducing space usage; when needed, it can be pulled out and rotated for convenient use. Combined with the tilt adjustment mechanism, the telescopic rotating bracket 83 enables multi-dimensional adjustments to the TV, ensuring users can find the optimal viewing angle.

[0096] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
