Description

Technical Field

[0001] This application relates to the field of monitor bracket technology, and more specifically, to an audio wall mount and a monitor bracket. Background Technology

[0002] As society progresses, people have higher and higher requirements for audiovisual atmosphere. The sound quality of the built-in speakers of TVs can no longer meet the needs of consumers. Therefore, consumers usually purchase separate speakers with higher sound quality.

[0003] Currently, most speakers are placed on tables or the floor on either side of the TV, or fixedly mounted on the wall. For TVs equipped with multi-functional TV mounts that can be extended, raised, or rotated, if the speakers remain in place after the TV's position is adjusted, it will affect the overall audiovisual atmosphere. Therefore, the speaker position needs to be adjusted separately after the TV's position is changed, which is cumbersome. Utility Model Content

[0004] The purpose of this application is to provide a speaker mount and a monitor stand, which aims to solve the technical problem in the prior art that the position of the speakers needs to be adjusted separately after the position of the TV is adjusted, which is cumbersome.

[0021] The beneficial effects of the speaker bracket provided in this application are as follows: Compared with the prior art, the speaker bracket of this application, by setting up a lifting mechanism and a horizontal mechanism, uses one of the column assembly and the sliding part in the lifting mechanism to install the telescopic part in the horizontal mechanism, and the other to install the support structure (or speaker), and uses the connecting part in the horizontal mechanism to install the speaker (or support structure). In this way, by adjusting the relative sliding position between the sliding part and the column assembly, the relative position of the column assembly and the sliding part in the vertical direction is changed, thereby changing the relative position of the speaker and the support structure in the vertical direction; by using the telescopic part in the horizontal mechanism to drive the connecting part to move along the first horizontal direction, the relative position of the connecting part and the lifting mechanism in the first horizontal direction is changed, thereby changing the relative position between the speaker and the support structure in the first horizontal direction.

[0022] The speaker mount provided in this application is suitable for monitor stands. When the speaker mount provided in this application is applied to a monitor stand, the supporting structure can be a monitor or a support body for mounting the monitor. The relative position between the speaker and the supporting structure can be adjusted via a lifting mechanism and a leveling mechanism. Once the speaker is adjusted to a suitable position, even if the position of the supporting structure is adjusted, the speaker can adjust its position synchronously with the supporting structure. This allows users to achieve a satisfactory audio-visual atmosphere without having to readjust the speaker, making operation simple and convenient.

[0023] The beneficial effects of the monitor bracket provided in this application are as follows: compared with the prior art, since the monitor bracket of this application includes the audio bracket provided by any of the above-mentioned technical solutions, it has at least all of the above-mentioned beneficial effects, which will not be repeated here.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure 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.

[0046] 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.

[0047] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0048] like Figure 1 As shown, one embodiment of this application provides a speaker bracket, including a lifting mechanism 1 and a horizontal mechanism 2. The lifting mechanism 1 includes a column assembly 100, an adjusting assembly 200, and a sliding part 300. The adjusting assembly 200 is mounted on the column assembly 100, and the sliding part 300 is slidably mounted on the column assembly 100 in a vertical direction and connected to the adjusting assembly 200. The adjusting assembly 200 is configured to adjust the relative sliding position between the sliding part 300 and the column assembly 100. The horizontal mechanism 2 includes a telescopic part 600 and a connecting part 700 connected to each other. The telescopic part 600 is mounted on either the column assembly 100 or the sliding part 300, and is configured to drive the connecting part 700 to move in a first horizontal direction. When the telescopic part 600 is mounted on the column assembly 100, one of the connecting part 700 and the sliding part 300 is used to connect to a support structure, and the other is used to connect to the speaker 3. When the telescopic part 600 is installed on the sliding part 300, one of the connecting part 700 and the column assembly 100 is used to connect to the support structure, and the other is used to connect to the speaker 3.

[0049] In this embodiment, the supporting structure can be a wall or other structure suitable for supporting the speaker mount. The speaker mount provided in this embodiment is applicable to monitor stands. When the speaker mount is applied to a monitor stand, the supporting structure can be the back panel of the monitor or a supporting body for mounting the monitor. Optionally, the monitor can be a television, computer screen, or other electronic display device.

[0050] The speaker bracket of this application embodiment includes a lifting mechanism 1 and a horizontal mechanism 2. One of the column assembly 100 and the sliding part 300 in the lifting mechanism 1 is used to install the telescopic part 600 in the horizontal mechanism 2, and the other is used to install a support structure (or speaker 3). The connecting part 700 in the horizontal mechanism 2 is used to install the speaker 3 (or the support structure). It is understood that when the support structure is installed on the column assembly 100 or the sliding part 300 that is not used to install the telescopic part 600 in the horizontal mechanism 2, the connecting part 700 of the horizontal mechanism 2 is used to install the speaker 3; conversely, when the speaker 3 is installed on the column assembly 100 or the sliding part 300 that is not used to install the telescopic part 600 in the horizontal mechanism 2, the connecting part 700 of the horizontal mechanism 2 is used to install the support structure. Thus, by adjusting the relative sliding position between the sliding part 300 and the column assembly 100 through the adjusting component 200, the relative position of the column assembly 100 and the sliding part 300 in the vertical direction changes, thereby changing the relative position of the speaker 3 and the supporting structure in the vertical direction. Furthermore, the telescopic part 600 in the horizontal mechanism 2 drives the connecting part 700 to move along the first horizontal direction, changing the relative position of the connecting part 700 and the lifting mechanism 1 in the first horizontal direction, and further changing the relative position of the speaker 3 and the supporting structure in the first horizontal direction. As can be seen, the lifting mechanism 1 and the horizontal mechanism 2 can adjust the relative position between the speaker 3 and the supporting structure, thereby adjusting the relative position between the speaker 3 and the display. Once the speaker 3 is adjusted to a suitable position, even if the position of the supporting structure is adjusted, the speaker 3 can adjust its position synchronously with the supporting structure, allowing the user to obtain a satisfactory audio-visual atmosphere without having to readjust the speaker 3, making the operation simple and convenient.

[0051] For ease of description, the following description will use the example of the telescopic part 600 being installed on the column assembly 100, the connecting part 700 being used to connect to the speaker 3, and the sliding part 300 being used to connect to the support structure. Optionally, the sliding part 300 can be directly connected to the support structure, or the sliding part 300 can be indirectly connected to the support structure by connecting to the support body on which the support structure is installed. Optionally, the sliding part 300 and the support structure or support body can be connected by auxiliary connectors (such as bolts or screws), snap-fitting, welding, or other suitable connection methods.

[0052] In one possible design, please refer to Figure 2 and Figure 3The adjusting assembly 200 includes a winding shaft 210, a rope 220, and a limiting assembly 230. The winding shaft 210 is rotatably mounted on the column assembly 100 about its own axis. A guide assembly 400 is provided on the column assembly 100. The rope 220 is arranged around the winding shaft 210 and the guide assembly 400, with a portion of the rope 220 wound around the winding shaft 210. A sliding part 300 is fixedly connected to the rope 220. The winding shaft 210 is configured to drive the rope 220 to rotate around the guide assembly 400 during its rotation about its own axis. The guide assembly 400 is configured to guide the rope 220 to rotate along a preset trajectory, so that the sliding part 300 slides vertically relative to the column assembly 100. The limiting assembly 230 is connected to both the winding shaft 210 and the column assembly 100, and is configured to restrict the rotation of the winding shaft 210 in at least one direction.

[0053] As can be seen from the above, the speaker bracket provided in this embodiment allows the sliding part 300 to slide vertically relative to the column assembly 100 simply by rotating the winding shaft 210. This means that the column assembly 100 and the sliding part 300 slide relative to each other in the vertical direction, thereby adjusting the position of the speaker 3 relative to the support structure in the vertical direction, making the operation simple. Furthermore, the use of the rope 220 in conjunction with the winding shaft 210 to allow the sliding part 300 to slide relative to the column assembly 100 facilitates precise control of the sliding distance of the sliding part 300 relative to the column assembly 100, thereby improving the accuracy of adjusting the lifting distance of the speaker 3 relative to the support structure. In this embodiment, the limiting component 230 at least restricts the rotation of the winding shaft 210 in one direction. Specifically, the limiting component 230 at least restricts the direction in which the winding shaft 210 rotates around its own axis when the speaker 3 needs to be lowered relative to the support structure. This direction can be clockwise or counterclockwise. For example, when the telescopic part 600 is installed on the column assembly 100, the support structure is connected to the sliding part 300, and the speaker 3 is connected to the connecting part 700, the limiting component 230 at least restricts the direction of rotation of the winding shaft 210 around its own axis when the sliding part 300 needs to move upward relative to the column assembly 100, that is, when the column assembly 100 moves downward relative to the sliding part 300. Thus, when the speaker 3 is adjusted to a suitable position relative to the support structure, the limiting component 230's restriction on the winding shaft 210 prevents the speaker 3 from automatically descending under its own weight, ensuring the speaker 3 is stably installed on the support structure and improving the reliability of the speaker bracket.

[0054] Optionally, the rope 220 can be made of steel wire rope. Steel wire rope has high structural strength and strong wear resistance, which helps to improve the load-bearing capacity and service life of the speaker bracket. In addition, the rope 220 can also be made of other materials, and there is no limitation here.

[0055] In some embodiments, the guide assembly 400 includes a first guide wheel, which is vertically spaced from the winding shaft 210. The rope 220 includes a first end and a second end. A portion of the rope 220 is wound around the winding shaft 210. The first end of the rope 220 extends from one side of the winding shaft 210 in a second horizontal direction and passes over the first guide wheel from the side opposite to the winding shaft 210. The second end of the rope 220 extends from the other side of the winding shaft 210 in the second horizontal direction and is connected to its first end. The second horizontal direction is perpendicular to the axis of the winding shaft 210. The second horizontal direction can be parallel to the first horizontal direction or at an angle to the first horizontal direction; for example, the second horizontal direction can be perpendicular to the first horizontal direction. The rope 220 has two vertical rope segments extending in the vertical direction. When the rope 220 is at rest, in the vertical direction, both vertical rope segments are located between the winding shaft 210 and the first guide wheel. One of the vertical rope segments is located on one side of the winding shaft 210 and the first guide wheel in the second horizontal direction, and the other vertical rope segment is located on the other side of the winding shaft 210 and the first guide wheel in the second horizontal direction. The two vertical rope segments mentioned above are referred to as the third vertical rope segment and the fourth vertical rope segment, respectively. When the winding shaft 210 rotates clockwise around its own axis, the rope 220 rotates clockwise around the winding shaft 210 and the first guide wheel along a racetrack-shaped trajectory. The third vertical rope segment moves vertically upward relative to the column assembly 100, and the fourth vertical rope segment moves vertically downward relative to the column assembly 100. When the winding shaft 210 rotates counterclockwise around its own axis, the rope 220 rotates counterclockwise around the winding shaft 210 and the first guide wheel along a racetrack-shaped trajectory. The third vertical rope segment moves vertically downward relative to the column assembly 100, and the fourth vertical rope segment moves vertically upward relative to the column assembly 100. One of the third and fourth vertical rope segments is fixedly connected to the sliding part 300. Thus, by rotating the winding shaft 210, the sliding part 300 and the column assembly 100 can slide relative to each other in the vertical direction, thereby adjusting the position of the speaker 3 relative to the support structure in the vertical direction.

[0056] In some embodiments, the limiting component 230 includes a limiting pin, the column component 100 is provided with a first limiting hole, and the winding shaft 210 is provided with a plurality of second limiting holes, which are spaced apart around the axis of the winding shaft 210. When the winding shaft 210 is rotated to adjust the speaker 3 to the target height, the winding shaft 210 is finely adjusted so that the second limiting hole on the winding shaft 210 closest to the first limiting hole is aligned with the first limiting hole. Then, the limiting pin is inserted into the second limiting hole and the first limiting hole. In this way, the rotation of the winding shaft 210 around its own axis in the clockwise and counterclockwise directions can be restricted, which helps to improve the stability of the speaker 3.

[0057] In other embodiments, please refer to Figure 3 and Figure 4 The limiting component 230 includes a one-way bearing 231 and a torsion spring 232. The inner ring of the one-way bearing 231 is sleeved on the winding shaft 210, and the torsion spring 232 is wound around the outer ring of the one-way bearing 231 and has an interference fit with the outer ring of the one-way bearing 231. One end of the torsion spring 232 is fixed to the column assembly 100. In this embodiment, the one-way bearing 231 being sleeved on the winding shaft 210 means that the one-way bearing 231 and the winding shaft 210 are coaxially arranged, and the inner ring of the one-way bearing 231 and the winding shaft 210 cooperate, so that the inner ring of the one-way bearing 231 and the winding shaft 210 can rotate synchronously. For example, the outer periphery of the winding shaft 210 is provided with a raised key 2121, and the inner wall of the inner ring is provided with a keyway 2311. The raised key 2121 is inserted into the keyway 2311, so that the inner ring and the winding shaft 210 can rotate synchronously. It is worth noting that the one-way bearing 231 refers to a bearing in which the inner ring can rotate freely relative to the outer ring in one direction (clockwise or counterclockwise) around its own axis, but cannot rotate relative to the outer ring in the other direction around its own axis. This configuration allows the winding shaft 210 to rotate smoothly in one direction around its own axis. When the winding shaft 210 needs to rotate in the other direction around its own axis, it will cause both the inner and outer rings of the one-way bearing 231 to rotate in the other direction around the axis of the winding shaft 210. However, because the torsion spring 232 is interference-fitted with the outer ring of the one-way bearing 231, and one end of the torsion spring 232 is fixed to the column assembly 100, the torsion spring 232 has a certain limiting effect on the rotation of the outer ring. Thus, it can effectively limit the rotation of the winding shaft 210 in the other direction around its own axis.

[0058] As can be seen from the above, the axis of the one-way bearing 231 coincides with the axis of the winding shaft 210. For ease of description, the axis of the winding shaft 210 will be referred to as the rotation axis in the following text.

[0059] Since the telescopic part 600 is installed on the column assembly 100, the support structure is connected to the sliding part 300, and the speaker 3 is connected to the connecting part 700, in this embodiment, the column assembly 100, the adjustment assembly 200, the horizontal mechanism 2, and the speaker 3 are all structures that can move relative to the support structure. For ease of description, the column assembly 100, the adjustment assembly 200, the horizontal structure, and the speaker 3 will be collectively referred to as movable components below.

[0060] In one example, when the winding shaft 210 rotates counterclockwise around the rotation axis, the sliding part 300 slides upward relative to the column assembly 100, that is, the column assembly 100 moves downward relative to the sliding part 300, causing the speaker 3 to move downward relative to the support structure; conversely, when the winding shaft 210 rotates clockwise around the rotation axis, the speaker 3 moves upward relative to the support structure. In this example, the inner ring can rotate clockwise relative to the outer ring around the rotation axis, but cannot rotate counterclockwise relative to the outer ring around the rotation axis. With this configuration, when the column assembly 100, the horizontal mechanism 2, and the speaker 3 in the movable assembly move downward relative to the supporting structure under the gravity of the movable assembly, the rope 220 moves and drives the winding shaft 210 to rotate counterclockwise. The winding shaft 210 drives both the inner and outer rings of the bearing to rotate counterclockwise around the axis of rotation, causing the torsion spring 232 to undergo elastic deformation. The torsion spring 232 exerts a torque on the outer ring of the bearing, causing it to rotate clockwise around the axis of rotation, and this torque gradually increases until the torque exerted by the torsion spring 232 on the outer ring of the bearing is sufficient to counteract the gravity of the movable assembly and the torque exerted on the winding shaft 210, allowing the speaker 3 to be suspended within the required height range relative to the supporting structure.

[0061] When it is necessary to move the speaker 3 downward relative to the supporting structure, a downward driving force can be applied to any of the column assembly 100, the horizontal mechanism 2, and the speaker 3, or a driving force that rotates counterclockwise around the rotation axis can be applied to the winding shaft 210. When the sum of the torque exerted by the driving force on the winding shaft 210 and the torque exerted by the weight of the movable component on the winding shaft 210 is greater than the torque exerted by the maximum frictional force between the torsion spring 232 and the outer ring on the winding shaft 210, the outer ring moves counterclockwise relative to the torsion spring 232 around the rotation axis, thereby enabling the winding shaft 210 to rotate counterclockwise around the rotation axis, and thus allowing the speaker 3 to move downward relative to the supporting structure. Furthermore, since the weight of the movable component offsets part of the frictional force between the torsion spring 232 and the outer ring, only a small driving force needs to be applied to any of the winding shaft 210, the column assembly 100, the horizontal mechanism 2, and the speaker 3 to adjust the height of the speaker 3 relative to the supporting structure, making the operation labor-saving and convenient.

[0062] In one possible design, such as Figure 2As shown, the column assembly 100 includes a mounting body 120 and two columns 110. The two columns 110 are spaced apart on the mounting body 120 along a second horizontal direction, and the sliding part 300 is slidably mounted on the two columns 110 along a vertical direction. By setting two columns 110, the sliding part 300 is slidably mounted on the two columns 110, which helps to improve the smoothness of the sliding part 300 relative to the column assembly 100, thereby improving the smoothness of adjusting the height of the speaker 3. Optionally, the mounting body 120 can be a sheet metal structure. Sheet metal structures have good structural strength and are easy to process, which helps to improve the service life of the speaker bracket and reduce production costs. Optionally, the mounting body 120 and the two columns 110 can be connected by auxiliary connectors (such as bolts or screws), welding, or other suitable connection methods, which are not limited here.

[0063] In some embodiments, such as Figure 2 and Figure 5 As shown, the sliding part 300 has a rod-shaped structure, and its length direction is parallel to the second horizontal direction. Optionally, the sliding part 300 has two first through holes 310 extending vertically, and the two first through holes 310 are spaced apart along the second horizontal direction. A column 110 passes through each first through hole 310. Optionally, the speaker bracket also includes a sliding sleeve 320, which has a sliding hole extending vertically. There can be two sliding sleeves 320, and one sliding sleeve 320 is inserted into each first through hole 310. The extension direction of the sliding hole is parallel to the extension direction of the first through hole 310, and the column 110 in each first through hole 310 also passes through the sliding hole on the sliding sleeve 320 in the first through hole 310. The inner wall of the sliding hole is relatively smooth, and the sliding sleeve 320 is made of wear-resistant material, which is beneficial for the sliding part 300 to slide relative to the column 110 and helps to improve the service life of the speaker bracket. Optionally, the sliding sleeve 320 passes through the entire first through hole 310, which can effectively improve the smoothness of the sliding part 300 relative to the column 110. Alternatively, the number of sliding sleeves 320 is four, with one sliding sleeve 320 inserted into the openings on the upper and lower sides of each first through hole 310. This helps to reduce the material used for the sliding sleeves 320, thereby reducing production costs.

[0064] Optionally, the sliding sleeve 320 and the sliding part 300 can be connected by any connection method such as interference fit, adhesive, snap-fit, or auxiliary connector. In one embodiment, the sliding sleeve 320 includes a sleeve part 321 and a flange part 322, a sliding hole is disposed through the sleeve part 321 in a vertical direction, and an edge part surrounds the outer periphery of the sleeve part 321 and is connected to the top or bottom region of the sleeve part 321. The sleeve portion 321 of the sliding sleeve 320 is inserted into the opening corresponding to the first through hole 310 on one side, and the flange portion 322 abuts against the sliding portion 300. The speaker bracket also includes a pressure plate 330, which has a second through hole through it. The number of pressure plates 330 is equal to the number of sliding sleeves 320. Multiple pressure plates 330 are arranged one-to-one with multiple sliding sleeves 320. Each pressure plate 330 is located on the side of the flange portion 322 of the corresponding sliding sleeve 320 that is away from the sliding portion 300, and each pressure plate 330 is connected to the sliding portion 300 to press the sliding sleeve 320 tightly against the sliding portion 300. The second through hole on each pressure plate 330 and the sliding hole on the corresponding sliding sleeve 320 are arranged vertically opposite each other to allow the column 110 in the corresponding first through hole 310 to pass through.

[0065] In one possible design, such as Figure 2 As shown, there are two guide components 400, each corresponding to one of the two columns 110. Each guide component 400 is distributed around the outer periphery of its corresponding column 110. A winding shaft 210 is rotatably mounted on the mounting body 120 and located between the two columns 110. A rope 220 is arranged around the winding shaft 210 and the two guide components 400, causing the rope 220 to rotate around the two columns 110 along an upright or inverted "U"-shaped trajectory. The rope 220 includes two first vertical rope segments and two second vertical rope segments. When the rope 220 rotates along the "U"-shaped trajectory, one of the first and second vertical rope segments rises while the other falls. A sliding part 300 is fixedly connected to each of the two first vertical rope segments, or vice versa. In this embodiment, the preset trajectory followed by the rope 220 under the guidance of the guide components 400 is specifically a "U"-shaped trajectory.

[0066] Understandably, when rope 220 rotates clockwise along the U-shaped trajectory, one of the first vertical rope segment and the second vertical rope segment rises while the other falls; conversely, when rope 220 rotates counterclockwise along the U-shaped trajectory, the movement direction of the first vertical rope segment and the second vertical rope segment is exactly opposite to the movement direction when rope 220 rotates clockwise.

[0067] In this embodiment, the sliding part 300 is fixedly connected to two first vertical rope segments, or the sliding part 300 is fixedly connected to two second vertical rope segments. This configuration allows the sliding part 300 to rise or fall relative to the two columns 110 via the two first or two second vertical rope segments, which helps to further improve the smoothness of the sliding part 300 relative to the column assembly 100, thereby further improving the smoothness of adjusting the height of the speaker 3.

[0068] In some embodiments, the sliding part 300 is fixedly connected to two first vertical rope segments. Optionally, the sliding part 300 and the first vertical rope segments can be connected by welding, binding, or other suitable methods. In other embodiments, the sliding part 300 is fixedly connected to two second vertical rope segments, and the sliding part 300 and the second vertical rope segments can be fixedly connected using the same connection method as the first vertical rope segments. For ease of description, the following description will use the fixed connection of the sliding part 300 to the first vertical rope segments as an example.

[0069] In one example, such as Figure 6 As shown, two rope clamps 270 are fixed at intervals on each first vertical rope segment, and the sliding part 300 is clamped between the two rope clamps 270 on each first vertical rope segment. Specifically, the rope clamp 270 includes a limiting block 271 and a pressing member 272, the pressing member 272 having an external thread; the limiting block 271 has a third through hole 2712 extending along the third horizontal direction, and the inner wall of the third through hole 2712 has an internal thread; the limiting block 271 has a receiving groove 2711 on one side surface in the fourth horizontal direction, the receiving groove 2711 communicating with the third through hole 2712, and the receiving groove 2711 extending through the limiting block 271 in the vertical direction. It is worth noting that the third horizontal direction and the fourth horizontal direction are set at an angle. With the third and fourth horizontal directions forming an angle, the third horizontal direction can be parallel to the first horizontal direction, parallel to the second horizontal direction, or forming an angle with both the first and second horizontal directions. Similarly, the fourth horizontal direction can be parallel to the first horizontal direction, parallel to the second horizontal direction, or forming an angle with both the first and second horizontal directions. The first vertical rope segment can extend into the receiving groove 2711 through its opening. One end of the clamping member 272 passes through the third through hole 2712, and the external thread of the clamping member 272 engages with the internal thread of the third through hole 2712. The clamping member 272 presses the first vertical rope segment against the inner wall of the receiving groove 2711, thereby fixing the rope clamp 270 onto the first vertical rope segment.

[0070] In some embodiments, such as Figures 5 to 8As shown, the rope 220 also passes through the first through hole 310 on the sliding part 300. Specifically, the first vertical rope segment and the second vertical rope segment on each column 110 are both passed through the sliding hole of the sliding sleeve 320 in the corresponding first through hole 310, and the second through hole opposite to the sliding hole. The limiting blocks 271 in the two rope clamps 270 on the first vertical rope segment abut against the pressure plates 330 on the upper and lower sides of the corresponding first through hole 310, respectively.

[0071] In one specific embodiment, such as Figure 2 As shown, the guide assembly 400 includes a first guide portion 410, a second guide portion 420, and a third guide portion 430. The first guide portion 410 and the second guide portion 420 are located on opposite sides of the corresponding column 110 in the second horizontal direction, respectively, and the third guide portion 430 is located on the upper or lower side of the corresponding column 110. One end of the rope 220 extends from one side of the winding shaft 210 in the second horizontal direction and passes sequentially around the first guide portion 410, the third guide portion 430, and the second guide portion 420 of one of the guide assemblies 400. The other end of the rope 220 extends from the other side of the winding shaft 210 in the second horizontal direction and passes sequentially around the first guide portion 410, the third guide portion 430, and the second guide portion 420 of another guide assembly 400 before being connected to one end of the rope 220. In this embodiment, the rope 220 between the first guide portion 410 and the third guide portion 430 of one guide assembly 400 is a first vertical rope segment, and the rope 220 between the second guide portion 420 and the third guide portion 430 is a second vertical rope segment. Similarly, the rope 220 between the first guide portion 410 and the third guide portion 430 of the other guide assembly 400 is a second vertical rope segment, and the rope 220 between the second guide portion 420 and the third guide portion 430 is a first vertical rope segment. Therefore, the sliding portion 300 is fixedly connected to the portion of the rope 220 located between the third guide portion 430 and the first guide portion 410 of one guide assembly 400, and the sliding portion 300 is also fixedly connected to the portion of the rope 220 located between the third guide portion 430 and the second guide portion 420 of the other guide assembly 400.

[0072] It is worth noting that the third guide portion 430 is located above or below the corresponding column 110. Specifically, on the vertical projection plane, the projection of the third guide portion 430 is located above or below the projection of the corresponding column 110. At least a portion of the third guide portion 430 may be directly opposite the corresponding column 110 in the vertical direction; or, on the horizontal projection plane, at least a portion of the projection of the third guide portion 430 may be located outside the projection of the corresponding column 110.

[0073] For ease of description, the following description will use the example of the third guide part 430 being located on the upper side of the corresponding column 110, the first guide part 410 being located on the side of the corresponding column 110 away from the other column 110, and the second guide part 420 being located on the side of the corresponding column 110 close to the other column 110.

[0074] In some embodiments, on a projection plane perpendicular to the second horizontal direction, at least a portion of the projection of the first guide portion 410 is located below the projection of the column 110, and at least a portion of the projection of the winding shaft 210 is also located below the projection of the column 110. Thus, when one end of the rope 220 passes over the first guide portion 410 from the winding shaft 210, friction between the rope 220 and the column 110 can be reduced. Optionally, on a horizontal projection plane, a portion of the projection of the third guide portion 430 is located on the side of the corresponding column 110 away from the other column 110, and another portion is located on the side of the corresponding column 110 closer to the other column 110. Thus, when the rope 220 passes over the third guide portion 430 from the first guide portion 410, and when it passes over the second guide portion 420 from the third guide portion 430, friction between the rope 220 and the column 110 can be effectively reduced, which is beneficial for improving the service life of the rope 220 and the smoothness of adjusting the height of the speaker 3.

[0075] In some embodiments, the first guide portion 410, the second guide portion 420, and the third guide portion 430 are all cylindrical, and the axes of the first guide portion 410, the second guide portion 420, and the third guide portion 430 are all arranged parallel to the axis of the winding shaft 210. This arrangement helps to improve the smoothness of the movement of the rope 220 relative to the first guide portion 410, the second guide portion 420, and the third guide portion 430, that is, to improve the smoothness of the rotation of the rope 220 along the "U"-shaped trajectory.

[0076] Optionally, the first guide portion 410 and the second guide portion 420 are rotatably mounted on the mounting body 120 around their own axes. Optionally, a mounting base may be provided on the upper side of the column 110, and the third guide portion 430 is rotatably mounted on the mounting base. With this configuration, when the rope 220 rotates along the U-shaped trajectory, the first guide portion 410, the second guide portion 420, and the third guide portion 430 rotate synchronously around their own axes, thereby reducing the friction between the rope 220 and the first guide portion 410, the second guide portion 420, and the third guide portion 430, and further improving the smoothness of the rope 220's rotation along the U-shaped trajectory.

[0077] Optionally, such as Figure 2 and Figure 8As shown, the third guide portion 430 includes a first rotating shaft 431 and a second rotating shaft 432, both of which are rotatably mounted on the upper side of the corresponding column 110. For example, the first rotating shaft 431 and the second rotating shaft 432 are respectively rotatably mounted on the mounting base around their own axes. Furthermore, on the horizontal projection plane, the projection of the first rotating shaft 431 is located on the side of the corresponding column 110 whose projection is farther away from the other column 110, while the second rotating shaft 432 is located on the side of the corresponding column 110 whose projection is closer to the other column 110. For ease of description, in the following content of this section, the column 110 located on the first side of the winding shaft 210 in the second horizontal direction will be referred to as the first column 110, and the column 110 located on the second side of the winding shaft 210 in the second horizontal direction will be referred to as the second column 110. The first side and the second side in the second horizontal direction are arranged opposite to each other. The guide component 400 corresponding to the first column 110 will be referred to as the first guide component 400, and the guide component 400 corresponding to the second column 110 will be referred to as the second guide component 400. The first guide component 400 is distributed on the outer periphery of the first column 110, and the second guide component 400 is distributed on the outer periphery of the second column 110. The rope 220 has a first end and a second end. The first end extends from the first side of the winding shaft 210 in the second horizontal direction and passes sequentially around the first guide portion 410, the first rotating shaft 431, the second rotating shaft 432, and the second guide portion 420 in the first guide assembly 400 before extending to the second side in the second horizontal direction. The second end extends from the second side of the winding shaft 210 in the second horizontal direction and passes sequentially around the first guide portion 410, the first rotating shaft 431, the second rotating shaft 432, and the second guide portion 420 in the second guide assembly 400 before extending to the first side in the second horizontal direction and connecting with the first end. In this way, the rope 220 can rotate along an upright "U"-shaped trajectory under the drive of the winding shaft 210.

[0078] Optionally, the adjusting assembly 200 also includes a connecting block, to which both ends of the rope 220 are respectively connected, thereby connecting the two ends of the rope 220. Optionally, the two ends of the rope 220 can also be connected in other ways, such as by fastening the two ends of the rope 220 together; or by welding, etc., without limitation.

[0079] In some embodiments, such as Figure 3 and Figure 4As shown, the adjustment assembly 200 also includes a fixed shaft 240, which is fixedly mounted on the mounting body 120. Optionally, the fixed shaft 240 can be screwed onto the mounting body 120, or it can be mounted onto the mounting body 120 by welding or interference fit, etc., without being limited to any one of these methods. The winding shaft 210 is rotatably mounted on the fixed shaft 240, and the winding shaft 210 and the fixed shaft 240 are coaxially arranged. The inner ring of the one-way bearing 231 is sleeved on the winding shaft 210. A raised key 2121 is provided on the outer circumferential surface of the winding shaft 210, and a keyway 2311 is provided on the inner wall of the inner ring. The raised key 2121 is inserted into the keyway 2311. Optionally, the winding shaft 210 is a stepped shaft structure, and the winding shaft 210 includes at least a first shaft segment 211 and a second shaft segment 212 that are connected to each other. The outer diameter of the first shaft segment 211 is larger than the outer diameter of the second shaft segment 212. The rope 220 can be wound around the first shaft segment 211. The inner ring of the one-way bearing 231 can be fitted onto the second shaft segment 212. The protruding key 2121 is specifically formed on the outer peripheral surface of the second shaft segment 212. Optionally, the adjusting assembly 200 further includes a bushing 250 and a protective cover 260. The bushing 250 is fitted onto the second shaft segment 212 and abuts against the side of the one-way bearing 231 away from the first shaft segment 211. The protective cover 260 covers the second shaft segment 212 and the one-way bearing 231 and bushing 250 on the second shaft segment 212. The protective cover 260 is connected to the mounting body 120, so that the bushing 250 and the one-way bearing 231 are limited between the protective cover 260 and the first shaft segment 211, and the one-way bearing 231 is axially limited relative to the winding shaft 210. A torsion spring 232 is located between the inner wall of the protective cover 260 and the outer peripheral surface of the one-way bearing 231. The torsion spring 232 is wound around the outer ring of the one-way bearing 231 and is interference-fitted with the outer ring of the one-way bearing 231. The mounting body 120 is provided with an anti-rotation groove 1211, and one end of the torsion spring 232 is inserted into the anti-rotation groove 1211, so that one end of the torsion spring 232 is fixed relative to the mounting body 120.

[0080] In one possible design, please refer to Figure 4 The first guide section 410 includes a guide cylinder 411 and a guide shaft 412. The guide shaft 412 is mounted on the mounting body 120, and its axis is parallel to the axis of the winding shaft 210. A limiting groove 4111 is formed on the outer circumferential surface of the guide cylinder 411, and a portion of the rope 220 is located within the limiting groove 4111. The guide cylinder 411 has an internal thread, and the guide shaft 412 has an external thread. The internal thread of the guide cylinder 411 and the external thread of the guide shaft 412 are engaged. A portion of the rope 220 is wound around the winding shaft 210 along a first helical trajectory. The lead of both the internal thread of the guide cylinder 411 and the lead of the external thread of the guide shaft 412 are the same as the lead of the first helical trajectory.

[0081] According to the above configuration, after the winding shaft 210 rotates once around its own axis, the rope 220 wound on the winding shaft 210 will move a distance of one lead along the axial direction of the winding shaft 210. Since the lead of the internal thread of the guide cylinder 411 and the lead of the external thread of the guide shaft 412 are the same as the lead of the first helical trajectory, and when the winding shaft 210 drives the rope 220 to rotate along the preset trajectory, the rope 220 drives the guide cylinder 411 to rotate relative to the guide shaft 412. Therefore, the guide cylinder 411 of each first guide part 410 can move the same distance synchronously with the rope 220 along the axial direction of the winding shaft 210. In this way, one end of the rope 220 can be wound around the winding shaft 210 in an orderly manner, and the other end can be released from the winding shaft 210 in an orderly manner, effectively avoiding the situation of the rope 220 getting caught on the winding shaft 210, which is beneficial to improving the smoothness of adjusting the height of the speaker 3.

[0082] Optionally, such as Figure 3 and Figure 4 As shown, a winding groove 2111 is formed on the outer peripheral surface of the winding shaft 210. The winding groove 2111 is a spiral groove, and the winding groove 2111 surrounds the outer peripheral surface of the winding shaft 210 along a first spiral trajectory. A portion of the rope 220 is wound around the winding shaft 210 along the winding groove 2111. Specifically, the winding groove 2111 surrounds the first shaft segment 211 of the winding shaft 210 along the first spiral trajectory.

[0083] In one possible design, such as Figure 2 , Figure 7 and Figure 8 As shown, at least one column 110 is provided with a tensioning part 510 and a tension adjusting member 520. The tensioning part 510 is movably mounted to the corresponding column 110 in the vertical direction via the tension adjusting member 520. A third guide part 430 corresponding to each column 110 is mounted on the tensioning part 510. The tension adjusting member 520 is configured such that the tensioning part 510 moves in the vertical direction relative to the corresponding column 110, thereby causing the third guide part 430 on the tensioning part 510 to move relative to the corresponding column 110. The distance between the third guide part 430 and the first guide part 410 and the second guide part 420 can be adjusted to adjust the tension of the rope 220.

[0084] In some embodiments, the two columns 110 are respectively provided with a tensioning part 510 and a tension adjusting member 520, and the connection method between the two columns 110 and the corresponding tensioning part 510 and tension adjusting member 520 is the same. Taking one of the columns 110 as an example, as follows... Figure 8As shown, the tensioning part 510 corresponding to the column 110 includes a cover 511 and a plate 512. The cover 511 has a slot on one side in the vertical direction, and the end of the column 110 away from the mounting body 120 is inserted into the slot. The third guide part 430 is located inside the slot and connected to the inner wall of the slot. Specifically, the first pivot 431 and the second pivot 432 of the third guide part 430 are both located inside the slot and connected to the inner wall of the slot. The rope 220 can extend into the slot through the slot opening, pass around the first pivot 431 and the second pivot 432 in sequence, and then extend out of the slot opening again. The slot includes a bottom wall opposite to its own opening and side walls surrounding the bottom wall. An adjustment port is provided through the bottom wall of the slot, and a support part is provided protruding from the side wall of the slot. The plate 512 is inserted into the slot and supported on the support part, and a fourth through hole is provided through the plate 512 in the vertical direction. The tension adjusting member 520 passes through the fourth through hole and abuts against the column 110. An internal thread is formed on the inner wall of the fourth through hole, and an external thread is formed on the tension adjusting member 520. The external thread on the tension adjusting member 520 engages with the internal thread in the fourth through hole. During the adjustment of the rope 220 tension, the operator's hand or tools can rotate the tension adjusting member 520 through the adjustment port, causing the tension adjusting member 520 to move relative to the plate 512 along the axis of the fourth through hole. This adjusts the vertical distance between the plate 512 and the column 110, thereby causing the cover 511 and the first and second rotating shafts 431 and 432 on the cover 511 to move vertically, thus achieving the purpose of adjusting the rope 220 tension.

[0085] Optionally, such as Figure 2 As shown, when the telescopic part 600 is installed on the column assembly 100, the telescopic part 600 can be connected to the mounting body 120 in the column assembly 100; or, the telescopic part 600 can also be connected to any column 110 in the column assembly 100.

[0086] In one example, the telescopic part 600 is connected to the mounting body 120. Optionally, the mounting body 120 includes a first mounting part 121 and a second mounting part 122, which are detachably connected. Two columns 110 are specifically mounted on the first mounting part 121, and the telescopic part 600 is specifically mounted on the second mounting part 122. The winding shaft 210 can be mounted on either the first mounting part 121 or the second mounting part 122. This configuration divides the mounting body 120 into two smaller structures (the first mounting part 121 and the second mounting part 122). During packaging and transportation, the placement of the first mounting part 121 and the second mounting part 122 within the packaging box can be flexibly adjusted to make reasonable use of the space inside the packaging box, thereby improving the convenience of transportation.

[0087] Optionally, the first mounting portion 121 and the second mounting portion 122 can be detachably connected by screws or clips. For example, the first mounting portion 121 and the second mounting portion 122 are fastened together by screws. Furthermore, a spacer 123 is provided between the first mounting portion 121 and the second mounting portion 122, which helps reduce wear between them, thereby increasing the service life of the speaker bracket. It also effectively prevents noise from collisions between the first mounting portion 121 and the second mounting portion 122, improving the user experience.

[0088] In one possible design, such as Figure 2 and Figure 9 As shown, the telescopic part 600 includes a first swing arm 610 assembly and a second swing arm 620 assembly, which are arranged crosswise and hinged to each other.

[0089] In some embodiments, when the telescopic part 600 is mounted on the sliding part 300, the connecting part 700 and the sliding part 300 are spaced apart along a first horizontal direction; one end of the first swing arm 610 assembly is hinged to the sliding part 300, and the other end is slidably mounted on the connecting part 700; one end of the second swing arm 620 assembly is hinged to the connecting part 700, and the other end is slidably mounted on the sliding part 300. In this configuration, by adjusting the included angle between the first swing arm 610 assembly and the second swing arm 620 assembly, the distance between the connecting part 700 and the sliding part 300 in the first horizontal direction can be adjusted, which also adjusts the distance between the speaker 3 and the support structure in the first horizontal direction.

[0090] In other embodiments, when the telescopic part 600 is installed on the column assembly 100, the connecting part 700 and the column assembly 100 are spaced apart along a first horizontal direction; one end of the first swing arm 610 assembly is hinged to the column assembly 100, and the other end is slidably installed on the connecting part 700; one end of the second swing arm 620 assembly is hinged to the connecting part 700, and the other end is slidably installed on the column assembly 100. In this arrangement, by adjusting the included angle between the first swing arm 610 assembly and the second swing arm 620 assembly, the distance between the connecting part 700 and the column assembly 100 in the first horizontal direction can be adjusted. Since the sliding part 300 is installed on the column assembly 100, the distance between the connecting part 700 and the sliding part 300 in the first horizontal direction can also be adjusted, that is, the distance between the speaker 3 and the support structure in the first horizontal direction can be adjusted.

[0091] In some embodiments, when the telescopic portion 600 is installed on the column assembly 100, the telescopic portion 600 is specifically installed on the mounting body 120 of the column assembly 100. Specifically, the telescopic portion 600 is specifically installed on the second mounting portion 122 of the mounting body 120. In this embodiment, the connecting portion 700 and the second mounting portion 122 are spaced apart along a first horizontal direction, and the first swing arm 610 assembly and the second swing arm 620 assembly are located between the connecting portion 700 and the mounting portion. One end of the first swing arm 610 assembly is specifically hinged to the second mounting portion 122, and the other end is slidably installed on the connecting portion 700; one end of the second swing arm 620 assembly is hinged to the connecting portion 700, and the other end is slidably installed on the second mounting portion 122.

The second hinge block 635 is slidably mounted on the connecting portion 700, and the first sliding end of each first swing arm 610 is hinged to the second hinge block 635 via the second spindle 636, so that the first sliding end of each first swing arm 610 is slidably mounted on the connecting portion 700. It is worth noting that the axes of the first spindle 634 and the second spindle 636 are both parallel to the axis of the hinge shaft 631, and the sliding direction of the first sliding end is perpendicular to the axis of the hinge shaft 631.

[0096] In some embodiments, the second swing arm 620 includes a second hinge end and a second sliding end. The second hinge end of each second swing arm 620 is hinged to the connecting portion 700, and the second sliding end of each second swing arm 620 is slidably mounted on the second mounting portion 122. It is worth noting that the sliding direction of the second sliding end is also perpendicular to the axis of the hinge shaft 631.

[0097] Optionally, the connecting portion 700 has a mounting groove on the side facing the second mounting portion 122, and the second hinge end of each second swing arm 620 extends into the mounting groove and is hinged to the connecting portion 700. A spacer post 637 is provided between the second hinge end of the upper second swing arm 620 and the top wall of the mounting groove, and another spacer post 637 is provided between the second hinge end of the lower second swing arm 620 and the bottom wall of the mounting groove. By providing the spacer post 637, the second swing arms 620 are spaced apart from the connecting portion 700, preventing friction between the second swing arms 620 and the connecting portion 700 when the second swing arms 620 rotate relative to the connecting portion 700.

[0098] Optionally, the second mounting portion 122 has a groove on the side facing the connecting portion 700, and the second sliding end of each second swing arm 620 extends into the groove. The telescopic portion 600 also includes two sliders 638, one slider 638 being slidably mounted on the top wall of the groove, and the other slider 638 being slidably mounted on the bottom wall of the groove.

[0099] In one possible design, there are multiple telescopic portions 600 and multiple connecting portions 700. The telescopic portions 600 are spaced apart along the second horizontal direction, and each telescopic portion 600 corresponds to a connecting portion 700. Each telescopic portion 600 is connected to its corresponding connecting portion 700, and each telescopic portion 600 is configured to drive its corresponding connecting portion 700 to move along the first horizontal direction. In this embodiment, the first and second horizontal directions are perpendicular. By providing multiple connecting portions 700, the area of ​​the horizontal mechanism 2 used for connecting with the speaker 3 or supporting structure is increased. This allows the speaker bracket to adapt to speakers 3 or supporting structures of various sizes, improving the versatility of the speaker bracket.

[0100] Optionally, such as Figure 2 As shown, there are two telescopic portions 600 and two connecting portions 700. The two telescopic portions 600 are installed at intervals along the second horizontal direction on the second mounting portion 122, and each connecting portion 700 is connected to the corresponding telescopic portion 600. When the telescopic portion 600 includes a first swing arm 610 assembly and a second swing arm 620 assembly, one end of the first swing arm 610 assembly of each telescopic portion 600 is hinged to the second mounting portion 122 and the other end is slidably installed on the connecting portion 700. One end of the second swing arm 620 assembly of each telescopic portion 600 is hinged to the connecting portion 700 and the other end is slidably installed on the second mounting portion 122. With this configuration, when both connecting parts 700 are connected to the same speaker 3, the distance between one connecting part 700 and the second mounting part 122, as well as the distance between the other connecting part 700 and the second mounting part 122, can be adjusted to allow the speaker 3 to rotate around the vertical axis within a certain range. This adjusts the angle between the speaker 3 and the supporting structure, which in turn adjusts the angle between the speaker 3 and the display, making the adjustment of the speaker 3 more flexible and able to meet the requirements of a higher audiovisual atmosphere.

[0101] Another embodiment of this application provides a monitor bracket, including a support body and an audio wall mount as described in any of the above embodiments. The support body is used to mount the monitor. In this embodiment, the support body is connected to the audio wall mount, or the monitor is connected to the audio wall mount, or the audio wall mount is connected to both the support body and the monitor. Since the monitor bracket provided in this embodiment includes the audio wall mount as described in any of the above embodiments, it has at least all of the above-described beneficial effects, which will not be elaborated further here.

[0103] Taking the example of the sliding part 300 being connected to both the support body and the display, the sliding part 300 is located between the support body and the back panel of the display and is connected to both. Optionally, the sliding part 300 can be connected to the support body and the back panel of the display by snap-fit, screw connection, or other suitable means. In one example, the support body has a through-hole, the sliding part 300 has a through-hole, the back panel of the display has a threaded hole, and the display bracket also includes screws. The screws pass through the first and second through-holes and engage with the threaded hole on the back panel of the display, thereby connecting the sliding part 300 to both the support body and the display.

[0104] In some embodiments, the support body may be connected to the display only via the sliding part 300, or a portion of the support body may be connected to the display via the sliding part 300, while another portion may be directly connected to the display. In one example, the support body has a plurality of first connection holes, some of which are located in the bottom region of the support body, and others in the top region. The sliding part 300 has a plurality of second connection holes, each corresponding to one of the first connection holes in the bottom region of the support body. The back panel of the display has a plurality of threaded holes, each corresponding to one of the first connection holes on the support body. The display bracket includes a plurality of screws, each corresponding to one of the first connection holes on the support body. The screws corresponding to the first connection holes in the bottom region of the support body pass through the corresponding first connection hole and second connection hole in sequence and then engage with the corresponding threaded hole. The monitor stand also includes multiple spacers located between the top area of ​​the support body and the back panel of the monitor. Each spacer corresponds to one of the multiple first connection holes in the top area of ​​the support body. Screws corresponding to the first connection holes in the top area of ​​the support body pass through the corresponding first connection hole, the spacer, and then engage with the corresponding threaded holes. This design improves the installation stability of the monitor.
