Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0023] To enhance the functionality and user experience of TV stands, some technologies incorporate a tilt adjustment mechanism that allows users to adjust the TV's tilt angle to improve the viewing experience. However, these tilt adjustment mechanisms suffer from a relatively large overall thickness.

[0024] Specifically, in related technologies, mechanisms that enable pitch angle adjustment are typically equipped with a single arc-shaped guide groove to allow the mounting base to rotate within a certain angle. However, in order to make the pitch angle adjustable range large, the arc length of the arc-shaped guide groove is relatively long, which in turn makes the overall thickness of the adjustment component relatively large.

[0025] This utility model proposes a TV stand that can adjust the TV tilt angle while reducing the overall thickness of the adjustment mechanism.

[0026] refer to Figure 1 , Figure 2 , Figure 5 and Figure 6The TV bracket 100 according to an embodiment of the present invention includes: a mounting base 101, a connecting component 102, and a supporting component 103. The mounting base 101 is used to mount a TV. The connecting assembly 102 includes a first component 201, a second component 202, and a connecting rod 301. The first component 201 is connected to the mounting base 101. Either the first component 201 or the second component 202 is provided with an arc-shaped guide groove 204, and the other is fixedly connected to the connecting rod 301. The connecting rod 301 passes through the arc-shaped guide groove 204 and can slide within the arc-shaped guide groove 204, so that the first component 201 can rotate relative to the second component 202 around the first axis 501. There are two arc-shaped guide grooves 204, and the center of each arc-shaped guide groove 204 coincides with the first axis 501. A connecting rod 301 passes through each arc-shaped guide groove 204. The two arc-shaped guide grooves 204 are located on both sides of the first axis 501 along the height direction, and the height direction is perpendicular to the extension direction of the first axis 501. By setting two arc-shaped guide grooves 204 on both sides of the height direction of the first axis 501 of the rotation center, the arc length of a single arc-shaped guide groove 204 is reduced while ensuring that the total adjustment stroke remains unchanged, and the rotation radius during the pitch angle adjustment process is reduced, thereby reducing the overall thickness of the adjustment mechanism formed by the first component 201 and the second component 202.

[0027] It should be noted that the total stroke mentioned above refers to the arc length required by the arc guide groove 204 corresponding to the total tilt angle of the TV during the tilt angle adjustment of the TV bracket 100. With the total arc length remaining unchanged, the design of this utility model can reduce the arc length of a single arc guide groove 204, thereby reducing its thickness.

[0028] It should be noted that in some embodiments of this utility model, such as Figure 5 As shown, the two arc-shaped guide grooves 204 are symmetrical about the horizontal plane passing through the first axis 501, and the two arc-shaped guide grooves 204 are located on the same circle. In practical applications, the two arc-shaped guide grooves 204 can be located on two concentric circles, and the centers of the two circles coincide with the first axis 501.

[0029] The support component 103 is connected to the second component 202. The support component 103 supports the mounting base 101. In use, the TV bracket can be connected to the wall through the support component 103, and the TV can be installed on the mounting base 101 to achieve wall-mounted installation of the TV. In this way, while ensuring that the total adjustment stroke remains unchanged, the arc length of a single arc-shaped guide groove 204 is reduced, and the rotation radius during the tilt angle adjustment process is reduced. This reduces the overall thickness of the adjustment mechanism formed by the first component 201 and the second component 202. Therefore, after the TV is installed through the TV bracket 100, the overall space occupied in the thickness direction can be effectively reduced, that is, the distance between the TV and the wall is reduced, improving the aesthetics. It is suitable for the installation of various TVs, especially for some thin TVs. The thin design makes the space occupied by the TV itself in the thickness direction smaller. Furthermore, by reducing the thickness of the connecting component 102, the space occupied by the TV bracket 100 in the thickness direction can be reduced, further improving the aesthetics of the TV bracket 100 mounted on the thin TV.

[0030] It should be noted that connecting rod 301 can be as follows: Figure 6 The detachable design shown can also be integrally formed on the first component 201 or the second component 202, with the other component having an arc-shaped guide groove 204.

[0031] Specifically, the arc-shaped guide groove 204 can be set on the first component 201 or the second component 202. Alternatively, the arc-shaped guide groove 204 above the first axis 501 can be set on the first component 201, and the arc-shaped guide groove 204 at the lower end can be set on the second component 202. It can be adjusted and designed according to different needs.

[0032] refer to Figure 2 and Figure 3 In some embodiments of this utility model, the second component 202 includes a main body 206 and a protrusion 207. Along the extending direction of the first axis 501, the main body 206 is connected to the first component 201, and the protrusion 207 protrudes in a direction away from the first component 201. The protrusion 207 is provided with a mounting groove 205, which is used to connect the support assembly 103, allowing the middle portion of the first component 201 (such as...) to... Figure 3 (As shown) No other components need to be connected, so the thickness of the first component 201 can be further reduced. On the other hand, the mounting groove 205 of the second component 202 is used to connect the support assembly 103, which allows the support assembly 103 and the second component 202 to partially overlap in the thickness direction, further reducing the overall size in the thickness direction and meeting the requirement of reducing thickness.

[0033] It should be noted that in some embodiments of this utility model, it can be as follows: Figure 3As shown, two second components 202 are symmetrically arranged on both sides of the first component 201 along the extension direction of the first axis 501. This allows the connecting arm assembly 104 of the support assembly 103 to be connected to both ends of the first component 201, facilitating subsequent extension, folding, and other processes, and improving the uniformity of force distribution. In some embodiments, a first component 201 and a second component 202 can be arranged side by side, which is sufficient to achieve connection with the support assembly 103 and rotation of the mounting base 101.

[0034] refer to Figure 1 and Figure 5 In some embodiments of this utility model, the first component 201 and the second component 202 at least partially overlap along the extending direction of the first axis 501. This overlap along the extending direction of the first axis 501 allows for overlapping dimensions in the thickness direction of the first component 201 and the second component 202, thereby further reducing the overall thickness. Further, referring to… Figure 5 When both the first component 201 and the second component 202 are in a vertical state, in the thickness direction, the first component 201 is completely located between the two ends of the second component 202, that is, the maximum thickness of the first component 201 is less than the maximum thickness of the second component 202, so as to maximize the reduction of the overall thickness.

[0035] It should be noted that the reference is... Figure 1 and Figure 5 The thickness direction refers to the direction that is perpendicular to both the extension direction of the first axis 501 and the height direction.

[0036] refer to Figure 1 and Figure 2 In some embodiments of this utility model, the support assembly 103 includes a back frame 105 and a connecting arm assembly 104. One end of the connecting arm assembly 104 is rotatably connected to the back frame 105, and the other end is rotatably connected to the mounting groove 205. The connecting arm assembly 104 is movable to change the distance between the back frame 105 and the mounting base 101. This design of the TV bracket 100 results in a wall-mounted type, allowing the back frame 105 to be fixedly installed on the wall, meeting the ultra-thin requirements of a wall-mounted TV bracket 100, improving aesthetics. Furthermore, the movable connecting arm assembly 104 can change the distance between the back frame 105 and the mounting base 101, enabling adjustment of the distance to the TV mounted on the mounting base 101, thus enhancing the functionality of the TV bracket 100.

[0037] Specifically, in some embodiments of this utility model, the connecting arm assembly 104 can be as follows: Figure 1 The setup shown is a hinged folding structure, but a multi-segment telescopic structure or a scissor structure can also be used, which can adjust the distance of the mounting base 101 through movement.

[0038] It should be noted that in some embodiments of this utility model, the support component 103 includes structures such as columns and bases, so that the TV bracket 100 is a vertical bracket, which can meet the requirement of reducing the thickness of the TV end of the vertical bracket.

[0039] refer to Figure 1 In some embodiments of this utility model, the connecting arm assembly 104 includes a first arm segment 106 and a second arm segment 107 rotatably connected. The first arm segment 106 is disposed in the mounting groove 205 and rotatably connected to the protrusion 207. The second arm segment 107 is rotatably connected to the back frame 105. The rotation axes at both ends of the first arm segment 106 and the second arm segment 107 extend along the height direction. The first arm segment 106 can rotate relative to the second arm segment 107 to change the distance between the back frame 105 and the mounting base 101. When the first arm segment 106 rotates relative to the second arm segment 107, the connection between the first arm segment 106 and the protrusion 207 and the connection between the second arm segment 107 and the back frame 105 both rotate, thereby changing the distance between the back frame 105 and the mounting base 101. This allows for the front and rear adjustment of the mounting base 101 and the television mounted on it, which can be directly adjusted by pushing and pulling the mounting base 101, making the operation intuitive and convenient.

[0040] It should be noted that the reference is... Figure 5 In some embodiments of this utility model, the first arm segment 106 passes through the first axis 501 along the centerline in the height direction, so that the force exerted by the first arm segment 106 on both ends of the first component 201 and the second component 202 is more uniform, thereby improving the stability of the first arm segment 106 when rotating relative to the connecting assembly 102 and reducing wear between components.

[0041] refer to Figure 5In some embodiments of this utility model, the connecting rods 301 in the two arc-shaped guide grooves 204 have the same sliding stroke. When one of the connecting rods 301 abuts against the front end of the arc-shaped guide groove 204, the other connecting rod 301 abuts against the rear end of the arc-shaped guide groove 204 in which it is located. The consistent sliding stroke within the two arc-shaped guide grooves 204 avoids unused strokes in individual arc-shaped guide grooves 204, thus preventing unnecessary thickness increases. Furthermore, by having one connecting rod 301 abut against the front end of the arc-shaped guide groove 204 while the other connecting rod 301 abuts against the rear end of its respective arc-shaped guide groove 204, it can be further ensured that the strokes within both arc-shaped guide grooves 204 are utilized. That is, during the rotation of the first component 201 relative to the second component 202 to the maximum and minimum angles, the connecting rods 301 within the two arc-shaped guide grooves 204 will move between the front and rear ends within their respective arc-shaped guide grooves 204, maximizing the utilization rate of the strokes of the arc-shaped guide grooves 204. This reduces the thickness of the arc-shaped guide grooves 204 while meeting the pitch angle adjustment requirements.

[0042] refer to Figures 1 to 3 as well as Figure 6 In some embodiments of this utility model, the connecting component 102 includes two second components 202, which are spaced apart on both sides of the first component 201 along the extension direction of the first axis 501. Providing multiple second components 202 allows structures such as the arc-shaped guide groove 204 and the connecting rod 301 to have four components, thereby making the connection and relative rotation of the first component 201 and the second component 202 more stable.

[0043] refer to Figure 2 , Figure 3 as well as Figure 6 In some embodiments of this utility model, the TV bracket 100 further includes a locking member 203. At least one of the two connecting rods 301 in each second component 202 is provided with the locking member 203. The locking member 203 has a locked state and an unlocked state. When the locking member 203 is in the locked state, it restricts the rotation of the first component 201 relative to the second component 202. When the locking member 203 is in the unlocked state, the first component 201 can rotate relative to the second component 202. The design of the locking member 203 allows the mounting base 101 to be adjusted to a suitable tilt angle before being fixed, improving the user experience.

[0044] Specifically, the locking element 203 can be configured in various ways. In some embodiments, it can be configured as follows: Figure 2 and Figure 6 The design shown is directly integrated with the connecting rod 301, and a threaded hole is provided on the first component 201, with a corresponding thread provided on the connecting rod 301, as shown. Figure 3As shown, the connecting rod 301 passes through the arc-shaped guide groove 204 and is threaded to the first component 201. Locking and unlocking can be achieved by turning the locking part 203, which is convenient to operate and reduces space occupation. Structures such as internal hexagonal holes can be opened on the end face of the locking part 203 to facilitate operation.

[0045] Furthermore, such as Figure 3 As shown, the TV bracket 100 also includes an anti-slip pad 302, which is disposed between the first component 201 and the second component 202. The locking component 203 passes through the arc-shaped guide groove 204 and is threadedly connected to the first component 201. During the tightening process, the anti-slip pad 302 can further prevent the first component 201 and the second component 202 from rotating relative to each other, thereby improving the structural stability in the locked state. Specifically, the anti-slip pad 302 can be a silicone pad, a rubber pad, a spring pad, or the like.

[0046] In some embodiments, the locking member 203 can also be a detachable nut. After the connecting rod 301 passes through the first component 201 and the second component 202, the locking member 203 is used to clamp and lock the two ends of the connecting rod 301. Alternatively, one end of the connecting rod 301 has a head, and the other end passes through the first component 201 and the second component 202 and is threadedly connected to the locking member 203. The locking member 203 and the head together clamp the first component 201 and the second component 202, which can also achieve locking of the two. The locking member 203 can take various forms.

[0047] refer to Figure 3 In some embodiments of this utility model, the locking member 203, connecting rod 301, and arc-shaped guide groove 204 are symmetrically arranged in two sets along the length direction, with any two of the length direction, height direction, and thickness direction being perpendicular to each other. Each set of locking member 203, connecting rod 301, and arc-shaped guide groove 204 has two in the height direction, so there are a total of four in both sets. The symmetrical design of four locking points can further improve the structural stability in the locked state, and the symmetrical design can also make the force more even.

[0048] It should be noted that in some embodiments of this utility model, three of the four locking members 203 can be set to the locked state and the other to the unlocked state. Reducing the number of locking members 203 in the locked state allows the user to adjust the pitch angle without loosening all the locking members 203, reducing the effort required for the initial adjustment.

[0049] In some embodiments of this utility model, the TV bracket 100 further includes an adjustment handle (not shown in the figure). The adjustment handle is connected to at least one locking member 203, and is used to switch the locking member 203 between a locked state and an unlocked state. This reduces the difficulty of adjustment; after loosening the other locking members 203, the state of the locking members 203 can be switched by adjusting the handle. The handle design increases the torque, making the adjustment process easier. Specifically, in some embodiments, when the locking member 203 has an internal hexagonal hole, the adjustment handle can be an internal hexagonal wrench. By turning the internal hexagonal wrench, the locking member 203 is in a locked state when tightened and in an unlocked state when loosened.

[0050] refer to Figure 5 In some embodiments of this utility model, the TV bracket 100 further includes a central shaft (not shown in the figure), which passes through the first component 201 and the second component 202, and is coaxial with the first axis 501. Since the axis of relative rotation of the first component 201 and the second component 202 is the first axis 501, setting a solid central shaft at the first axis 501 can improve the stability of their relative rotation. It should be noted that when the TV bracket is equipped with a central shaft, the radius of the arc of the arc-shaped guide groove 204 needs to be determined first to determine the position of the first axis 501, and then the central shaft is set at the coaxial position of the first axis to ensure that the axis of rotation of the arc-shaped guide groove 204 is the axis of the central shaft.

[0051] It should be noted that the reference is... Figure 4 In some embodiments of this utility model, the mounting base 101 further includes an assembly part 401 and an adjustment part 402. The assembly part 401 is used to mount the television, and the adjustment part 402 is connected to the first component 201. The adjustment part 402 is detachably connected to the assembly part 401. The assembly part 401 is provided with a plurality of stop holes 403 spaced apart along the height direction. The adjustment part 402 can be connected to different stop holes 403 to change the position of the assembly part 401 relative to the first component 201 along the height direction. This design enables the television bracket 100 to also have a height adjustment function, further enhancing the functionality of the television bracket 100.

[0052] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
