[0038] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0039] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0040] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0041] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0042] The inventor of the present application has developed a television stand, one embodiment of which is as follows: Figures 1 to 21 As shown, it includes a wall panel 2 and a suspension rocker arm 1, the wall panel 2 is installed on the wall, the suspension rocker arm 1 has two groups and is arranged oppositely on the left and right sides of the wall panel 2, the suspension rocker arm 1 includes a base 11, a first connecting rod 12 and a second connecting rod 13, the base 11 is detachably connected to the wall panel 2, one end of the first connecting rod 12 is rotatably pivoted to the base 11, the other end of the first connecting rod 12 is rotatably pivoted to one end of the second connecting rod 13, the other end of the second connecting rod 13 is suitable for connecting to a TV 300, and the TV 300 is rotatably connected to the second connecting rod 13, the suspension rocker arm 1 A limit assembly 14 is also provided on the TV 300, and the limit assembly 14 is suitable for limiting the rotation angles of the first connecting rod 12 and the base 11 and the second connecting rod 13 and the first connecting rod 12, respectively. When the user applies a displacement force on the TV 300, the rotation directions of the first connecting rod 12 and the second connecting rod 13 are opposite, and when the TV stand is in an extended state, the maximum rotation angle between the first connecting rod 12 and the base 11 is α, which satisfies 0°<α<90°, and the maximum rotation angle between the second connecting rod 13 and the first connecting rod 12 is β, which satisfies 0°<β-α<90°. It is worth mentioning that the displacement force refers to the force that causes the TV stand to change from a folded state to an extended state, which will not cause the TV 300 to rotate around a vertical axis.

[0043] By limiting the maximum rotation angle between the base 11 and the first link 12, and the maximum rotation angle between the first link 12 and the second link 13, and satisfying 0°<α<90° and 0°<β-α<90°, it is possible to avoid the first link 12 and the second link 13 being parallel to each other in the extended state, or the second link 13 being completely perpendicular to the TV 300, causing a dead point position, thereby affecting the use of the suspension rocker arm of the present application.

[0044] It is worth mentioning that Figure 1As shown, the suspension rocker arms 1 are arranged oppositely on the left and right sides of the wall panel 2, which means that the two groups of suspension rocker arms 1 are symmetrical. Specifically, the rotation direction of the first link 12 and the second link 13 in the suspension rocker arm 1 arranged on the left side is different from the rotation direction of the first link 12 and the second link 13 in the suspension rocker arm 1 arranged on the right side. In this specific embodiment, Figure 1 As shown, the suspension rocker arm 1 includes a first suspension rocker arm 100 and a second suspension rocker arm 200 which are arranged opposite to each other. The structures of the first suspension rocker arm 100 and the second suspension rocker arm 200 are symmetrically arranged, and both include a first connecting rod 12 and a second connecting rod 13. During the use of the TV stand, the rotation directions of the first connecting rod 12 and the second connecting rod 13 in the first suspension rocker arm 100 and the second suspension rocker arm 200 are different.

[0045] like Figure 5 As shown, when it is necessary to control the TV stand from a folded state to an unfolded state, the first link 12 in the first suspension rocker arm 100 arranged on the left is suitable for clockwise rotation, and the second link 13 is suitable for counterclockwise rotation; the first link 12 in the second suspension rocker arm 200 arranged on the right is suitable for counterclockwise rotation, and the second link 13 is suitable for clockwise rotation.

[0046] In addition, since the maximum rotation angle between the first connecting rod 12 and the base 11 is α, which satisfies α<90°, and the maximum rotation angle between the second connecting rod 13 and the first connecting rod 12 is β, which satisfies 0°<β-α<90°, therefore, on the premise of meeting the above conditions, it can also be concluded that the maximum rotation angle β between the second connecting rod 13 and the first connecting rod 12 has a value range of 90°<β<180°.

[0047] Further preferably, Figures 6 to 18 As shown, the suspension rocker arm 1 includes a first pivot 15, one end of the first connecting rod 12 is rotatably pivoted to the base 11 through the first pivot 15, and the limiting assembly 14 includes a first limiting plate 141, the first limiting plate 141 is coaxially arranged with the first pivot 15, one side of the first limiting plate 141 is upwardly protruded with a first mounting protrusion 1411, and the lower part of the first connecting rod 12 is provided with a first mounting groove 121 matching with the first mounting protrusion 1411, the first mounting protrusion 1411 is suitable for being inserted into the first mounting groove 121, and limiting the relative position relationship between the first limiting plate 141 and the first connecting rod 12, and a first limiting portion 1412 is radially protruded outwardly on the first limiting plate 141, when the first connecting rod 12 and the base 11 rotate relative to each other, the first limiting portion 1412 is suitable for contacting the side wall of the base 11 and limiting the maximum rotation angle of the first limiting plate 141, thereby limiting the maximum unfolding rotation angle of the first connecting rod 12 relative to the base 11.

[0048] like Figure 7 and Fig. 9 The TV stand of the present application is shown in a folded state, at which time the first limiting portion 1412 on the first limiting piece 141 is still at a certain distance from the base 11; Figure 8 and Fig.10 The TV stand of the present application is shown in an unfolded state, at which the first limiting portion 1412 on the first limiting piece 141 abuts against the base 11 and limits the first connecting rod 12 from further rotating. A first mounting protrusion 1411 is provided on one side of the first limiting piece 141 to facilitate fixing the relative position of the first limiting piece 141 and the first connecting rod 12, so that the first connecting rod 12 can rotate around the first pivot 15 while driving the first limiting piece 141 to rotate, thereby changing the relative position relationship between the first limiting portion 1412 and the base 11.

[0049] Further preferably, Fig.11 As shown, a first friction plate 143 is installed between the first limiting plate 141 and the base 11. The first friction plate 143 is elastic and is suitable for controlling the friction between the first limiting plate 141 and the base 11. The first friction plate 143 can better control the friction between the first limiting plate 141 and the base 11, thereby facilitating the control of the first connecting rod 12 to be in a hovering state at any time during the rotation process.

[0050] Further preferably, Figures 13 to 18 As shown, the suspension rocker arm 1 also includes a second pivot 16, and the other end of the first link 12 is rotatably pivoted with the second link 13 through the second pivot 16. When the second link 13 rotates, it is suitable to drive the second pivot 16 to rotate synchronously. The limiting assembly 14 also includes a second limiting plate 142, and the second limiting plate 142 is sleeved on the second pivot 16 and rotates synchronously with the second pivot 16. A second limiting portion 1421 is radially protruding outward on the second limiting plate 142, and a limiting stopper 1231 is protruding downward on the lower part of the first link 12. When the second link 13 rotates relative to the first link 12, the second limiting portion 1421 is suitable for contacting the limiting stopper 1231 and limiting the maximum rotation angle of the second limiting plate 142, thereby limiting the maximum unfolding rotation angle of the second link 13 relative to the first link 12.

[0051] In this specific embodiment, Fig.13 and Fig.15 It shows that when the first connecting rod 12 and the second connecting rod 13 are in the folded state, there is a distance between the second limiting piece 142 and the limiting block 1231; Fig.14 and Fig.16As shown in the figure, when the first link 12 and the second link 13 are in the unfolded state, the second limit piece 142 abuts against the limit stopper 1231, thereby limiting the maximum unfolding rotation angle of the second link 13 relative to the first link 12. Such a configuration has a relatively simple structure, can effectively reduce the use cost and manufacturing cost, and can reduce the volume required by the limit assembly 14.

[0052] Further preferably, Figures 13 to 18 As shown, a stopper 123 is provided at the lower part of the first connecting rod 12, a limit stopper 1231 is provided on the stopper 123 protruding downward, a second mounting protrusion 1232 is provided on the stopper 123 protruding upward, and a second mounting groove 122 (such as Fig. 22 The blocking piece 123 is suitable for being detachably connected to the first connecting rod 12 through the second mounting protrusion 1232 and the second mounting groove 122. The blocking piece 123 is provided, and the limit stopper 1231 and the second mounting protrusion 1232 are provided on the blocking piece 123, so that the blocking piece 123 can be conveniently installed at the lower part of the first connecting rod 12, and when the first connecting rod 12 and the second connecting rod 13 rotate around the second pivot 16, the blocking piece 123 can remain relatively still with the first connecting rod 12, so as to facilitate the control of the maximum rotation angle of the second connecting rod 13 relative to the first connecting rod 12.

[0053] Further preferably, Fig.17 and Fig.18 As shown, Fig.17 As shown, the blocking piece 123 is arranged on the upper part of the second limiting piece 142, and a second friction piece 144 is arranged between the blocking piece 123 and the second limiting piece 142. The second friction piece 144 is elastic and is suitable for controlling the friction between the second limiting piece 142 and the blocking piece 123, and then controlling the friction between the second limiting piece 142 and the first connecting rod 12. Since the second limiting piece 142 and the blocking piece 123 will rotate relative to each other, the second friction piece 144 is additionally provided to control the friction between the second limiting piece 142 and the blocking piece 123, so as to achieve the purpose of hovering at any time.

[0054] Further preferably, Fig.17 and Fig.18As shown, the lower end of the second pivot 16 is detachably provided with an adjusting screw 162, and an adjusting piece 161 is sleeved on the adjusting screw 162. The adjusting piece 161 is disc-shaped and the middle part is protruding downward. The upper part of the adjusting piece 161 contacts the second limiting piece 142. The adjusting screw 162 is suitable for adjusting the upper and lower positions of the adjusting piece 161 and controlling the friction between the second limiting piece 142 and the blocking piece 123. By controlling the position of the adjusting screw 162 in the vertical direction, the pressure between the adjusting screw 162 and the adjusting piece 161 is controlled, and the elastic deformation of the adjusting piece 161 is changed, and the friction between the second limiting piece 142 and the blocking piece 123 is more conveniently controlled, so that the use of the TV bracket of the present application can be more personalized, that is, by controlling the position of the adjusting screw 162, the purpose of controlling the magnitude of the friction is achieved, so as to adjust the torque of rotation between the first connecting rod 12 and the second connecting rod 13, so that the motion performance of the suspension rocker arm 1 is changed.

[0055] Further preferably, Figures 19 to 21 As shown, the suspension rocker arm 1 includes a suspension component 17, and the suspension component 17 includes a suspension seat 171. The television 300 is suitable for being installed on the suspension seat 171, and the suspension seat 171 is rotatably pivoted to the end of the second connecting rod 13 away from the first connecting rod 12. The limiting component 14 includes a limiting column 145 arranged in the vertical direction, and the limiting column 145 is installed on the second connecting rod 13, and the upper part of the limiting column 145 protrudes from the second connecting rod 13. The upper part of the limiting column 145 is suitable for contacting the upper part of the suspension seat 171 and limiting the rotation angle of the suspension seat 171. The suspension component 17 also includes an inclination changing component 172 and a suspension platform 173. The suspension platform 173 is adjustably connected to the suspension seat 171 through the inclination changing component 172. The television 300 is suitable for being installed on the suspension platform 173, and the inclination adjustment of the television 300 is realized by controlling the action of the inclination changing component 172.

[0056] like Fig.19 As shown, the top of the limit column 145 is shown to protrude from the second connecting rod 13, wherein the suspension assembly 17 does not interfere with the limit column 145; Fig. 20 It is shown that the top of the limiting column 145 protrudes from the second connecting rod 13, wherein the suspension assembly 17 rotates a certain angle, and the limiting column 145 is used to limit the rotation angle of the suspension seat 171.

[0057] It is worth mentioning that the inclination angle changing component 172 is a prior art, such as Fig.21As shown, it includes a handle 1721 and a tilt adjustment column 1722. A tilt adjustment slot 1731 is provided on the side of the suspension platform 173. The tilt adjustment column 1722 is movably provided in the tilt adjustment slot 1731. When the tilt angle of the suspension platform 173 needs to be adjusted, the handle 1721 is released to allow the tilt adjustment column 1722 to move in the tilt adjustment slot 1731. When adjusted to a suitable position, the handle 1721 is locked to allow the tilt adjustment column 1722 and the tilt adjustment slot 1731 to be in a relatively fixed state, thereby limiting the tilt adjustment of the suspension platform 173.
