Description

Technical Field

[0001] This application belongs to the field of display bracket technology, and more specifically, relates to a display bracket. 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's tilt angle structure are as follows: After installing the TV onto 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 TV can be easily turned by hand to adjust its tilt angle. Finally, tighten the adjustment handle 2 to secure it. However, during the process of adjusting the TV's tilt angle, to prevent the TV from suddenly flipping and falling to the lowest point, one hand must be used to hold the TV steady while the other hand operates the adjustment handle 2, which is inconvenient. Utility Model Content

[0004] The purpose of this application is to provide a display bracket to solve the technical problem that existing TV wall mounts are inconvenient to operate when adjusting the tilt angle.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a display bracket is provided, comprising: a base, the base having a first opening and a second opening and a third opening located on both sides of the first opening; a swing base, the swing base having a first hole, a second hole and a third hole, the first hole corresponding to the first opening, the second hole corresponding to the second opening, and the third hole corresponding to the third opening; a first connector, the first connector being movably connected to the first hole and the first opening, one of the first hole and the first opening being a first arc-shaped hole; a second connector, the second connector being movably connected to the second hole and the second opening, one of the second hole and the second opening being a second arc-shaped hole; and a third connector, the third connector being movably connected to the third opening and the third hole, one of the third hole and the third opening being a third arc-shaped hole; wherein the center of the second arc-shaped hole and the center of the third arc-shaped hole do not coincide with the center of the first arc-shaped hole, so that the swing base remains stationary after rotating relative to the base.

[0006] In one alternative embodiment, the second arc-shaped hole and the third arc-shaped hole are arranged symmetrically about the horizontal center line passing through the center of the first arc-shaped hole.

[0007] In one optional embodiment, the distance from the center of the second arc-shaped hole to the center line of the first arc-shaped hole is 5mm to 20mm; and / or, the distance from the center of the third arc-shaped hole to the center line of the first arc-shaped hole is 5mm to 20mm.

[0008] In one optional embodiment, the base is provided with a first connecting plate and a second connecting plate, each of which is provided with a corresponding second opening and a third opening; the swing seat is provided with a third connecting plate and a fourth connecting plate, each of which is provided with a corresponding first hole and a second hole; the swing seat is sleeved on the base, and the first connecting member and the second connecting member are respectively sequentially inserted through the third connecting plate, the first connecting plate, the second connecting plate and the fourth connecting plate.

[0009] In one optional embodiment, the second connector includes a second rotating shaft, the second rotating shaft including a second shaft body and second limiting portions disposed at both ends of the second shaft body, the second shaft body passing through two second holes and two second openings, and the second limiting portions abutting against the outer side wall of the swing seat; and / or, the third connector includes a third rotating shaft, the third rotating shaft including a third shaft body and third limiting portions disposed at both ends of the third shaft body, the third shaft body passing through two third holes and two third openings, and the third limiting portions abutting against the outer side wall of the swing seat.

[0010] In one alternative embodiment, the swing base has a rotating part and a hanging strip part. The rotating part is provided with a first hole, a second hole and a third hole. The hanging strip part is connected to the rotating part and is used to connect a display device.

[0011] In an alternative embodiment, the first connector includes a screw and an adjusting handle. The screw is connected to the base and configured not to rotate relative to the base. The screw passes through a first opening and a first hole and is connected to the adjusting handle.

[0012] In an alternative embodiment, the display bracket further includes a wall panel, to which the base is fixedly connected, and the wall panel is used for fixed connection with the mounting structure.

[0013] In one alternative embodiment, at least two bases are provided, which are disposed on the wall panel and spaced apart along the extension direction of the wall panel, and the number of swing seats corresponds to the number of bases.

[0014] In an optional embodiment, the display bracket further includes a telescopic rotating frame, one end of which is rotatably connected to the base and the other end of which is rotatably connected to the wall panel.

[0015] The beneficial effects of the display bracket provided in this application are as follows: Compared with the prior art, the display bracket of this application embodiment sets the center of the second arc-shaped hole and the center of the third arc-shaped hole to not coincide with the center of the first arc-shaped hole. When the display device (such as a television) tends to fall downwards under the action of gravity, the second and third connecting members generate a reverse force and friction on the second and third arc-shaped holes. Under the combined action of the second and third connecting members and the gravity of the television, the entire structure can form an asymmetrical torque distribution at any angle, achieve torque balance, and form a natural stable position point, preventing the television and the swing base from rotating downwards. That is, when the swing base is rotated to adjust the television to a certain angle, the device will automatically maintain that angle and will not continue to droop or flip due to gravity. Users can adjust the angle of the television with only one hand without worrying that the television will suddenly fall, thus achieving the convenience of one-handed operation.

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, 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.

[0035] 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.

[0036] However, this mechanism has the following drawbacks: during the process of adjusting the TV 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 adjustment handle 2 with the other hand at all times, which is quite cumbersome; after multiple adjustments, the adjustment handle 2 may become worn out and fail, and even if the adjustment handle 2 is turned all the way, it cannot provide the pre-tightening force required to lock the TV; when the TV is relatively heavy, users with less strength will find it difficult to tighten the adjustment handle 2.

[0037] Please refer to the following: Figures 2 to 10The display bracket 100 provided in this application embodiment will now be described. The display bracket 100 includes: a base 10, which has a first opening 11 and a second opening 12 and a third opening 13 located on both sides of the first opening 11; a swing seat 20, which has a first hole 21, a second hole 22 and a third hole 23, wherein the first hole 21 is correspondingly disposed to the first opening 11, the second hole 22 is correspondingly disposed to the second opening 12, and the third hole 23 is correspondingly disposed to the third opening 13; and a first connector 30, which is movably connected to the first hole 21 and the first opening 11, wherein one of the first hole 21 and the first opening 11 is an arc-shaped first arc hole 2. 11; a second connector 40, which is movably connected to the second hole 22 and the second opening 12, one of which is a second arc-shaped hole 121; and a third connector 50, which is movably connected to the third opening 13 and the third hole 23, one of which is a third arc-shaped hole 131; wherein the center of the second arc-shaped hole 121 and the center of the third arc-shaped hole 131 do not coincide with the center of the first arc-shaped hole 211, so that the swing seat 20 remains stationary after rotating relative to the base 10.

[0038] The base 10 is used to connect to a mounting structure, such as a wall or other structure for mounting display devices. The base 10 has three openings, with the first opening 11 located in the middle.

[0039] The swing base 20 is used to mount display devices (such as televisions, monitors, etc.). The swing base 20 has three holes corresponding to the openings in the base 10: the first hole 21 corresponds to the first opening 11, the second hole 22 corresponds to the second opening 12, and the third hole 23 corresponds to the third opening 13, for rotational connection with the openings in the base 10. In each of the three sets of holes, only one hole in each set needs to be an arc-shaped hole to allow the swing base 20 to rotate relative to the base 10; the other hole can be designed as a circular hole or other limiting hole. In some embodiments, such as... Figure 4 The first hole 21 is designed as a first arc-shaped hole 211, and the second hole 12 and the third hole 13 are designed as a second arc-shaped hole 121 and a third arc-shaped hole 131, respectively.

[0040] The first connector 30, the second connector 40, and the third connector 50 are respectively inserted into three sets of holes. The connectors can be configured as bolts or rotating shafts. The connectors can slide within the arc-shaped holes.

[0041] The fact that the centers of the second arc-shaped hole 121 and the third arc-shaped hole 131 do not coincide with the center of the first arc-shaped hole 211 means that the centers of the three arc-shaped holes are in different positions. As a result, when the swing base 20 rotates relative to the base 10, the connecting parts form an asymmetrical torque distribution structure. When the swing base 20 drives the television to rotate to any tilt angle, the second connecting part 40 and the third connecting part 50 generate an asymmetrical constraint torque under the combined action of the television's own weight and the friction of the connecting parts, so as to achieve stable suspension at different angles.

[0042] By designing three arc-shaped holes with non-coincident centers, the connecting parts generate opposing forces and friction through these holes, achieving dynamic torque balance. This allows the television to automatically lock its position regardless of the viewing angle. This design eliminates the risk of displacement due to gravity and enables users to adjust the tilt angle with one hand.

[0043] like Figure 8 The center of the second arc-shaped hole 121 is located above the center of the first arc-shaped hole 211, and the center of the third arc-shaped hole 131 is located below the center of the first arc-shaped hole 211. When the swing seat 20 rotates relative to the base 10, since the centers of the second arc-shaped hole 121 and the third arc-shaped hole 131 do not coincide with the center of the first arc-shaped hole 211, the second connector 40 and the third connector 50 will have a relative sliding tendency in different directions within their respective arc-shaped holes. This relative motion tendency causes the second connector 40 and the third connector 50 to generate frictional forces in different directions with the arc-shaped holes. The frictional forces and the gravity of the television form an asymmetrical torque distribution, achieving torque balance at multiple positions.

[0044] When in use, the TV is mounted on the swing stand 20. Users can hold the edge of the TV with one hand and gently push or pull to adjust the TV angle. Due to the non-coincident center of gravity, the TV will remain stable at any angle without the need for additional locking.

[0045] The above solution achieves convenient one-handed operation of the display stand 100. Due to the non-coincident arc-shaped hole design, the device can naturally and stably position itself at any angle under the combined action of the TV's gravity and the friction of the connecting parts. This allows users to adjust the TV angle with just one hand without worrying about the TV suddenly falling. Simultaneously, the device automatically maintains the adjusted angle, preventing it from drooping or flipping due to gravity, thus improving safety and stability. Furthermore, this design simplifies the adjustment process, eliminating the need for additional locking steps, further enhancing operational convenience. It is also reusable multiple times, ensuring safety and reliability.

[0046] Compared with the prior art, the display bracket 100 provided in this application embodiment, by setting the center of the second opening 12 and the third opening 13 of the base 10 to not coincide with the center of the third hole 23 of the swing seat 20, when the display device (such as a television) tends to fall downwards under the action of gravity, the second opening 12 and the third opening 13 of the base 10 can respectively generate a reverse force on the first hole 21 and the second hole 22 of the swing seat 20 through the first connector 30 and the second connector 40, preventing the television and the swing seat 20 from rotating downwards. The entire structure can form an asymmetrical torque distribution at any angle, thereby achieving torque balance at multiple positions. Under the combined action of the television's gravity and the friction between the first connector 30 and the second connector 40, a natural stable position point can be formed at any angle. Rotating the swing seat 20 adjusts the television to a certain angle, and the device will automatically maintain that angle and will not continue to droop or flip due to gravity. Users can adjust the angle of the television with only one hand without worrying that the television will suddenly fall, thus achieving the convenience of one-handed operation.

[0047] Please refer to some embodiments of this application. Figure 5 and Figure 8 The second arc-shaped hole 121 and the third arc-shaped hole 131 are arranged symmetrically with the horizontal center line passing through the center of the first arc-shaped hole 211 as the axis of symmetry.

[0048] The horizontal center line refers to the straight line extending horizontally along the display bracket 100 in normal use. The horizontal center line passes through the center of the first arc-shaped hole 211 and is perpendicular to the direction of gravity. Figures 8 to 10 The straight line X indicated in the figure is the horizontal centerline. The second arc-shaped hole 121 and the third arc-shaped hole 131 are symmetrically arranged along the horizontal centerline of the first arc-shaped hole 211. When the second arc-shaped hole 121 and the third arc-shaped hole 131 are respectively provided on the base 10 and the swing seat 20, the second arc-shaped hole 121 and the third arc-shaped hole 131 are located on two different planes. The axially symmetrical arrangement of the second arc-shaped hole 121 and the third arc-shaped hole 131 can be understood as follows: the first arc-shaped hole 211, the second arc-shaped hole 121 and the third arc-shaped hole 131 are all projected onto a parallel plane corresponding to the base 10 or the swing seat 20, and the second arc-shaped hole 121 and the third arc-shaped hole 131 are axially symmetrically arranged with the horizontal centerline passing through the center of the first arc-shaped hole 211 as the axis of symmetry.

[0049] The positions of the second arc-shaped hole 121 and the third arc-shaped hole 131 are designed symmetrically to achieve consistency in spatial layout, ensuring that their relative positional relationship with the first arc-shaped hole 211 is the same.

[0050] like Figure 8Under ideal conditions where the swing seat 20 is in its initial vertical state, is not subject to external adjustment force, and the center of gravity of the television is located in the plane of symmetry, the forces generated by the second connecting member 40 and the third connecting member 50 in their respective arc holes are equal in magnitude and symmetrical in direction, which is beneficial to improving the initial balance and assembly stability of the structure.

[0051] By symmetrically arranging the second arc-shaped hole 121 and the third arc-shaped hole 131, the force on both sides of the swing base 20 can be more balanced during adjustment, reducing unilateral load, improving the smoothness of operation and the consistency of feel, and also helping to extend the structural life. For example, when the swing base 20 rotates around the center of the first arc-shaped hole 211, the second connecting member 40 and the third connecting member 50 slide along their respective trajectories under the constraint of the symmetrically arranged second arc-shaped holes 121 and third arc-shaped holes 131. Since the centers of the second arc-shaped holes 121 and third arc-shaped holes 131 do not coincide with the center of the first arc-shaped hole 211, the second connecting member 40 and the third connecting member 50 generate frictional forces and contact reaction forces with the corresponding arc-shaped holes in opposite directions and with magnitudes varying with the angle during the sliding process. The asymmetrical torque design balances the gravitational torque generated by the television, enabling the swing base 20 to achieve stable suspension at any adjustment angle. The symmetrical layout of the second arc-shaped hole 121 and the third arc-shaped hole 131 helps to make the motion resistance distribution of the connecting parts on both sides more balanced during the adjustment process, reduce the phenomenon of unilateral jamming or uneven load, and improve the smoothness of operation and the consistency of feel.

[0052] Meanwhile, this symmetrical design further simplifies the assembly process and ensures the accuracy of the opening positions, thereby improving the reliability and smoothness of the overall structure.

[0053] The symmetrical arrangement of the second arc-shaped hole 121 and the third arc-shaped hole 131 makes the force on the swing base 20 more balanced during rotation, making the structure of the display bracket 100 more stable, reducing the shaking of the swing base 20 during adjustment, and improving the safety and adjustment accuracy of the display bracket 100. The symmetrical arrangement simplifies the manufacturing process and reduces production costs.

[0054] Working principle: such as Figures 5 to 8As shown, let point O be the center of the first arc-shaped hole 211. Since the centers of the second arc-shaped hole 121 and the third arc-shaped hole 131 do not coincide with the center of the first arc-shaped hole 211, the second connecting member 40 and the third connecting member 50 will restrict the swing seat 20 from rotating around the rotation axis of the first connecting member 30. This causes the swing seat 20 to slide along the arc groove of the first arc-shaped hole 211 along the first connecting member 30, that is, the swing seat 20 can only rotate around the center of point O. Let O1 be the center of the third arc-shaped hole 131, and R1 be the radius of the circle corresponding to the third arc-shaped hole 131; let O2 be the center of the second arc-shaped hole 121, and R2 be the radius of the circle corresponding to the second arc-shaped hole 121. O1 and O2 are symmetrical with respect to the center line X passing through the center of the first arc-shaped hole 211. At this moment, the second arc-shaped hole 121 and the third arc-shaped hole 131 are axially symmetrical about the center line of the first arc-shaped hole 211. From the above conditions, we know that R1 = R2 at this moment. Further derivation based on geometric relationships shows that the distance from the center O of the first arc-shaped hole 211 to the second arc-shaped hole 121 and the third arc-shaped hole 131 is the same. Figure 8 This can form a circle with center O and radius R. Let the weight of the television be G. Under the influence of the television's gravity, the television and the swing base 20 tend to rotate counterclockwise downwards with center O. If the center O1 of the third arc-shaped hole 131 and the center O2 of the second arc-shaped hole 121 coincide with the rotation axis O, the television and the swing base 20 will inevitably rotate flexibly downwards with center O. However, since the center O1 of the third arc-shaped hole 131 and the center O2 of the second arc-shaped hole 121 do not coincide with the rotation axis O, the second connecting member 40 and the third connecting member 50 generate opposing forces with their corresponding arc-shaped holes, preventing the television and the swing base 20 from rotating counterclockwise downwards. Therefore, without applying external force, the television's pitch angle will remain self-balancing in its current state.

[0055] The rotation of the swing base 20 relative to the base 10 is actually the process of the center of a circle with point O as the center and radius R as the radius changing. Adjusting the tilt angle of the television by moving it up and down is equivalent to adjusting the rotation axis of the swing base 20. (Comparison) Figures 9 to 10 The axis of rotation relative to the same reference datum Figure 8 It can also be seen that, under different states, the rotation axis O of the swing seat 20 relative to the base 10 is dynamic and changes with the rotation.

[0056] In some embodiments of this application, the distance from the center of the second arc-shaped hole 121 to the center line of the first arc-shaped hole 211 is 5mm to 20mm.

[0057] In some embodiments of this application, the distance from the center of the third arc-shaped hole 131 to the center line of the first arc-shaped hole 211 is 5mm to 20mm.

[0058] The center line here is defined in the same way as the horizontal center line mentioned above. The center line refers to the straight line extending horizontally in the normal use state of the display bracket 100. The center line passes through the center of the first arc-shaped hole 211 and is perpendicular to the direction of gravity.

[0059] When the first arc-shaped hole 211, the second arc-shaped hole 121, and the third arc-shaped hole 131 are respectively provided on the base 10 and the swing seat 20, the first arc-shaped hole 211, the second arc-shaped hole 121, and the third arc-shaped hole 131 are all projected onto a parallel plane corresponding to the base 10 or the swing seat 20. The distance from the center of the second arc-shaped hole 121 or the center of the third arc-shaped hole 131 to the center line of the first arc-shaped hole 211 is the distance from the point to the line.

[0060] By controlling the distance from the center of the second arc hole 121 and the third arc hole 131 to the center line of the first arc hole 211, the torque difference in different directions can be adjusted. The greater the distance, the greater the offset of the center, and the greater the reverse resistance generated, which helps to enhance the hovering effect. A range of 5mm to 20mm is formed to ensure sufficient asymmetrical torque without affecting the operating feel.

[0061] The non-coincident center design generates opposing torques in different directions at the connection points. These torques combine and vary at different angles, creating local torque equilibrium points at multiple angles. With the distance limited to 5mm to 20mm, a stable point can be formed at multiple angles, enabling hovering at any angle. This appropriate distance design allows users to change the angle with minimal force; simultaneously, the structure automatically maintains the current angle after the user releases their grip.

The first connecting piece 30 and the second connecting piece 40 pass through the connecting plates on both sides, transforming the double-sided connection between the swing seat 20 and the base 10 into a four-point support, enhancing the connection rigidity and strengthening the connection strength, and realizing a stable connection structure between the base 10 and the swing seat 20.

[0066] When the swing seat 20 rotates relative to the base 10, the openings and holes on the connecting plates on both sides form a symmetrical force path, and the connecting parts form a uniformly distributed friction force between the connecting plates on both sides, avoiding deflection or shaking caused by unilateral force, so that the swing seat 20 can rotate stably on the base 10, while ensuring the overall structural integrity.

[0067] With the symmetrical layout of the double-sided connecting plates and the through-type installation of the connectors, the connection stability between the base 10 and the swing seat 20 is improved. When the user operates with one hand, the swing seat 20 will not be accidentally displaced due to uneven force, thus realizing the operation requirement of adjusting the TV angle with one hand.

[0068] Therefore, the display stand 100 can withstand a large load and remain stable when adjusting the angle of the TV, avoiding the risk of the TV suddenly falling and improving safety.

[0069] In addition, the third hole 23 and the third opening 13 can also be designed in the above form, that is, the first connecting plate 14 and the second connecting plate 15 are provided with corresponding third openings 13, and the third connecting plate 241 and the fourth connecting plate 242 are provided with corresponding first holes 21 and second holes 22, with the same effect as above, which will not be described in detail here.

[0070] Please refer to some embodiments of this application. Figure 3 The second connector 40 includes a second rotating shaft, which includes a second shaft body and second limiting portions located at both ends of the second shaft body. The second shaft body passes through two second holes 22 and two second openings 12, and the second limiting portions abut against the outer wall of the swing seat 20.

[0071] Please refer to some embodiments of this application. Figure 3 The third connector 50 includes a third rotating shaft, which includes a third shaft body and third limiting portions located at both ends of the third shaft body. The third shaft body passes through two third holes 23 and two third openings 13, and the third limiting portions abut against the outer wall of the swing seat 20.

[0072] The second or third shaft can be a cylindrical metal rod, the diameter of which forms a clearance fit with the diameter of the second hole 22 and the third opening 13; or it can be a screw 31 structure. The second or third limiting part can be formed into a flange by riveting or stamping, the outer diameter of which is larger than the diameter of the corresponding through hole on the outer wall of the swing seat 20, forming an axial constraint after assembly; or it can be a fastener or an annular flange structure, which is fixed to the end of the shaft by machining.

[0073] During the installation process, the second rotating shaft passes through the second hole 22 of the third connecting plate 241, the second opening 12 of the first connecting plate 14, the second opening 12 of the second connecting plate 15, and the second hole 22 of the fourth connecting plate 242 in sequence. The third shaft passes through the third hole 23 on the third connecting plate 241, the third opening 13 on the first connecting plate 14, the third opening 13 on the second connecting plate 15, and the third hole 23 on the fourth connecting plate 242 in sequence.

[0074] The second and third limiting parts abut against the outer walls of the third connecting plate 241 and the fourth connecting plate 242 of the swing seat 20, respectively, to prevent the second and third rotating shafts from falling off the swing seat 20, thereby preventing the shafts from moving in the horizontal direction while allowing the shafts to rotate within the arc-shaped hole.

[0075] The above structure, through the combination of the limiting part and the shaft, retains the rotational freedom of the swing seat 20 relative to the base 10 while eliminating the risk of axial displacement. When adjusting the TV angle with one hand, the cooperation between the rotating shaft and the limiting part can maintain a stable distribution of frictional torque, avoiding torque imbalance caused by shaft movement.

[0076] A reliable connection and smooth rotation between the swing base 20 and the base 10 are achieved. The second connector 40 and the third connector 50 allow them to work together to form a torque balance at multiple positions on the swing base 20, thereby maintaining the stability of the swing base 20 at any angle. This structure avoids the risk of the television suddenly flipping or falling during adjustment, improving the safety and ease of use of the display bracket 100. At the same time, the supporting action of the second and third limiting parts effectively prevents the connectors from falling off, further enhancing the stability and reliability of the overall structure.

[0077] Please refer to some embodiments of this application. Figure 3 The swing base 20 has a rotating part 24 and a hanging part 25. The rotating part 24 is provided with a first hole 21, a second hole 22 and a third hole 23. The hanging part 25 is connected to the rotating part 24 and is used to connect the display device.

[0078] The hanging part 25 and the rotating part 24 can be an integrally formed structure; or they can be designed as two independent structures, which are fixed by mechanical connection (such as threaded connection or riveting).

[0079] The hanging strip 25 can be provided with a separate mounting interface for easy fixation to a display device (such as a television); the hanging strip 25 can be adapted to televisions of different sizes without modifying the design of the rotating part 24. In some embodiments, such as Figure 3 The surface of the hanging strip 25 is provided with multiple mounting holes, which can be fixed to the interface on the back of the TV with bolts, etc., making the installation of the TV more convenient.

[0080] The hanging strip 25 can be designed as a flat, hook-shaped, or elongated structure, and its surface can be provided with threaded holes, snaps, or other perforations. The connection interface between the hanging strip 25 and the television can be provided with anti-slip textures or a cushioning layer.

[0081] The rotating part 24 includes three holes, which are connected to the openings on the base 10 via connectors to form a movable fit. That is, the rotating part 24 is provided with opposing third connecting plates 241 and fourth connecting plates 242.

[0082] The television set is securely connected to the swing base 20 via the hanging strip 25, achieving a reliable connection between the swing base 20 and the television set, allowing the television set to be stably mounted on the wall mount. When adjusting the television angle, the rotating part 24 moves relative to the base 10 around the arc-shaped hole trajectory, and the hanging strip 25 deflects synchronously with the rotating part 24. This rigid connection ensures the stability of the television set's posture, and the rotating part 24 can be suspended at any angle, making the television angle adjustment more flexible and convenient. This structural design also improves the load-bearing capacity and stability of the entire wall mount, ensuring the safety of the television set during adjustment.

[0083] Please refer to some embodiments of this application. Figure 3 The first connector 30 includes a screw 31 and an adjusting handle 32. The screw 31 is connected to the base 10 and is configured not to rotate relative to the base 10. The screw 31 passes through the first opening 11 and the first hole 21 and is connected to the adjusting handle 32.

[0084] The purpose of adjusting handle 32 is to prevent accidental changes in the TV's tilt angle. Therefore, before adjusting the TV's tilt angle, the adjusting handle 32 should be loosened and locked after adjustment.

[0085] Screw 31 is connected to base 10 and does not rotate relative to base 10. It can be fixed to a preset position on base 10 by welding or riveting, or as... Figure 3 and Figure 4 As shown, a polygonal anti-rotation part is provided on the screw 31, and a polygonal hole that mates with the anti-rotation part is provided on the base 10. The adjusting handle 32 is configured with an internal thread, and its end has a handle structure for easy manual rotation. After the screw 31 passes through the first hole 21 of the swing seat 20 and the first opening 11 of the base 10 in sequence, it mates with the internal thread of the adjusting handle 32. By rotating the adjusting handle 32, its insertion depth in the screw 31 can be changed, thereby adjusting the tightness of the connection between the base 10 and the swing seat 20.

[0086] In other words, the tightness can be adjusted by rotating the adjusting handle 32 along the thread axis of the screw 31. No other tools are needed; angle fixing and releasing can be achieved simply by rotating the handle with one hand, making the display bracket 100 easy to adjust. Users can adjust the friction between the swing base 20 and the base 10 by rotating the adjusting handle 32, thereby adjusting the tilt angle of the television. When adjusted to the appropriate position, tightening the adjusting handle 32 will fix the swing base 20, improving operational convenience and safety. Furthermore, because the display bracket 100 has a self-balancing characteristic, tightening the adjusting handle 32 does not require excessive force.

[0087] Please refer to some embodiments of this application. Figure 2 The display bracket 100 also includes a wall panel 60, and the base 10 is fixedly connected to the wall panel 60. The wall panel 60 is used for fixed connection with the mounting structure.

[0088] By setting the wall panel 60, the reliability of the connection between the display bracket 100 and the main structure of the building can be significantly enhanced, and the base 10 can avoid displacement and deformation when bearing the load of the television. The modular design of the installation structure enables the bracket to be quickly positioned and installed, while ensuring that a stable rigid support system is formed between the base 10 and the wall, providing a basic load-bearing platform for the angle adjustment function of the swing seat 20.

[0089] The wall panel 60 can be made of metal sheet with multiple mounting holes on its surface. The distribution of the mounting holes matches the preset fixing points of the mounting structure. The base 10 can be fixed to the surface of the wall panel 60 by welding, hanging, or bolting. The edges of the wall panel 60 can be provided with a flange structure to increase rigidity. The mounting structure is a wall or bracket, and the wall panel 60 is fixed to the mounting structure by expansion bolts or self-tapping screws.

[0090] Through the rigid connection between the wall panel 60 and the installation structure, the load of the base 10 is evenly distributed to the surface of the installation structure, avoiding deformation or loosening caused by local stress concentration. At the same time, it simplifies the installation process, eliminating the need to directly process complex fixing structures on the base 10.

[0091] Please refer to some embodiments of this application. Figure 2 At least two bases 10 are provided, and at least two bases 10 are provided on the wall panel 60 and are spaced apart along the extension direction of the wall panel 60. The number of swing seats 20 corresponds to the number of bases 10.

[0092] Setting up at least two bases 10 and a number of swing seats 20 corresponding to the number of bases 10, providing at least two-point support, can increase the torsional stiffness of the overall structure, prevent the swing seats 20 from shifting laterally or flipping during adjustment, and improve the stability of the hanger during tilting, rotating and other actions.

[0093] The weight of the television is transferred to at least two bases 10 via two swing seats 20, reducing the stress on individual connection points, minimizing fatigue damage to connectors, and improving the load-bearing capacity and service life of the wall mount. Even if one connection point becomes slightly loose or fails, the other connection points can still provide temporary support.

[0094] At least two swing mounts 20 can rotate synchronously, ensuring that the TV remains horizontal during adjustment. The connection points between the swing mounts 20 and the base 10 are more widely distributed, resulting in a more uniform torque distribution; the arc-shaped hole design with non-coincident centers helps to achieve more precise torque balance control and improve hovering performance.

[0095] In some embodiments of this application, the display bracket 100 further includes a telescopic rotating frame (not shown in the figure), one end of which is rotatably connected to the base 10, and the other end of which is rotatably connected to the wall panel 60.

[0096] The telescopic rotating bracket allows for both telescopic extension (e.g., adjusting the distance between the TV and the wall) and left / right rotation (adjusting the angle), providing greater installation flexibility. The telescopic rotating bracket can be rotatably connected to the base 10 and wall panel 60 via either a hinge or a bushing connection.

[0097] The design of the swing base 20, telescopic rotating bracket and wall panel 60 forms a sturdy overall frame, which allows the entire display bracket 100 to distribute the weight of the TV more evenly, enhances the stability of the overall structure, and ensures that the TV will not easily shake or shift after installation.

[0098] When two bases 10 are provided, the two bases 10 can be connected by a connector, and the telescopic rotating frame is rotatably connected to the connector.

[0099] In some embodiments, the telescopic rotating frame includes an arm assembly comprising a first horizontal bar and a second horizontal bar, one end of the first horizontal bar being rotatably connected to the base 10, the other end of the first horizontal bar being rotatably connected to one end of the second horizontal bar, and the other end of the second horizontal bar being rotatably connected to the wall panel 60; or, the arm assembly includes one first horizontal bar and two second horizontal bars, one end of the first horizontal bar being rotatably connected to the base 10, the two second horizontal bars being spaced apart in a vertical direction, the other end of the first horizontal bar being located between the two second horizontal bars and rotatably connected to one end of the two second horizontal bars, and the other ends of the two second horizontal bars being rotatably connected to the wall panel 60.

[0100] In some embodiments, the number of arm assemblies is two sets.

[0101] Users can change the left and right orientation of the display by controlling the base 10 to rotate relative to the first horizontal bar. At the same time, users can also adjust the distance between the display device and the wall panel 60 by controlling the angle between the first and second horizontal bars.

[0102] The telescopic swivel stand 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 swivel stand enables multi-dimensional adjustments to the TV, ensuring users can find the optimal viewing angle.

[0103] 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.
