Description

Technical Field

[0001] This utility model relates to the field of bracket technology, and in particular to an angle adjustment device and a screen bracket. Background Technology

[0002] With the widespread use of display devices (such as televisions, projectors, and monitors) in offices, education, and home entertainment, users have placed higher demands on the installation flexibility and angle adjustment capabilities of these devices. As a common method of display device installation, screen brackets are widely welcomed in the market due to their advantages such as space saving and convenient installation.

[0003] However, while existing screen brackets generally offer height adjustment, most lack vertical tilt adjustment, failing to meet users' personalized viewing angle needs in various scenarios. Some screen brackets rely on the friction between screws and contact surfaces to fix the angle by using a combination of rotation and fixing points. However, over long-term use, factors such as vibration and material fatigue gradually weaken the screw's tightening force, leading to reduced friction. This makes it difficult to maintain the set tilt angle of the display device in the vertical plane, resulting in issues like automatic slippage and angle changes, affecting stability and reliability. Furthermore, existing structures require users to repeatedly tighten or loosen screws to adjust the angle, which is cumbersome, time-consuming, and laborious, and makes precise angle adjustment difficult.

[0024] This invention provides an angle adjustment device and a screen bracket. The angle adjustment device includes a first connecting member, a second connecting member, an adjustment mechanism, and a tilt adjustment assembly. The second connecting member is rotatable relative to the first connecting member, allowing the adjustment mechanism and the tilt adjustment assembly to adjust the rotation angle of the second connecting member relative to the first connecting member. The adjustment mechanism includes a driving member and a driven member. The driven member is slidably engaged with both the first and second connecting members. The driving member is rotatably mounted on the first connecting member and is drively connected to the driven member, driving the driven member to move, thereby causing the second connecting member to rotate relative to the first connecting member. This achieves more stable and precise angle adjustment of the second connecting member, avoiding angle changes caused by unstable friction. The tilt adjustment assembly is positioned between the first and second connecting members.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] With the widespread use of display devices (such as televisions, projectors, and monitors) in offices, education, and home entertainment, users have placed higher demands on the installation flexibility and angle adjustment capabilities of these devices. As a common method of display device installation, screen brackets are widely welcomed in the market due to their advantages such as space saving and convenient installation.

[0039] However, while existing screen brackets generally offer height adjustment, most lack vertical tilt adjustment, failing to meet users' personalized viewing angle needs in various scenarios. Some screen brackets rely on the friction between screws and contact surfaces to fix the angle by using a combination of rotation and fixing points. However, over long-term use, factors such as vibration and material fatigue gradually weaken the screw's tightening force, leading to reduced friction. This makes it difficult to maintain the set tilt angle of the display device in the vertical plane, resulting in issues like automatic slippage and angle changes, affecting stability and reliability. Furthermore, existing structures require users to repeatedly tighten or loosen screws to adjust the angle, which is cumbersome, time-consuming, and laborious, and makes precise angle adjustment difficult.

[0040] Therefore, there is an urgent need for an angle adjustment device and a screen bracket to solve the above-mentioned technical problems.

[0041] like Figures 1-7 As shown, this embodiment provides an angle adjustment device, which includes a first connecting member 1, a second connecting member 2, an adjustment mechanism 3, and a tilt adjustment component 4. The second connecting member 2 is rotatable relative to the first connecting member 1. The adjustment mechanism 3 includes a driving member 31 and a driven member 32. The driven member 32 is slidably engaged with both the first connecting member 1 and the second connecting member 2. The driving member 31 is rotatably mounted on the first connecting member 1 and is drively connected to the driven member 32, and is used to drive the driven member 32 to move, thereby causing the second connecting member 2 to rotate relative to the first connecting member 1. The tilt adjustment component 4 is disposed between the first connecting member 1 and the second connecting member 2, and is used to guide and restrict the rotational movement of the second connecting member 2 relative to the first connecting member 1.

[0042] In this embodiment, the second connecting member 2 is rotatable relative to the first connecting member 1, so that the rotation angle of the second connecting member 2 relative to the first connecting member 1 can be adjusted by the adjusting mechanism 3 and the tilt adjustment assembly 4. The adjusting mechanism 3 includes a driving member 31 and a driven member 32. The driven member 32 is slidably engaged with both the first connecting member 1 and the second connecting member 2. The driving member 31 is rotatably mounted on the first connecting member 1 and is drively connected to the driven member 32, which drives the driven member 32 to move, thereby causing the second connecting member 2 to rotate relative to the first connecting member 1. This achieves a more stable and precise angle adjustment of the second connecting member 2, avoiding angle changes caused by unstable friction. The tilt adjustment assembly 4 is disposed between the first connecting member 1 and the second connecting member 2. By guiding and restricting the rotational movement of the second connecting member 2 relative to the first connecting member 1, the tilt adjustment assembly 4 can effectively guide the movement trajectory of the second connecting member 2, ensuring the smoothness of the rotation process, while limiting its range of motion to prevent excessive rotation of the second connecting member 2, which could lead to structural damage or instability. With the above settings, the angle adjustment device of this embodiment can achieve stable and precise pitch angle adjustment in the vertical plane, and has higher reliability and more convenient operation.

[0043] The specific structure of the angle adjustment device is described below:

[0044] Specifically, such as Figures 1-3 As shown, the first connector 1 includes multiple plate-like structures, which together form a roughly cubic frame structure. The plate-like structures are not only easy to process and manufacture, but also improve the structural strength and stability of the first connector 1, reduce the weight of the device, and help reduce processing costs.

[0045] Specifically, such as Figures 1-3 As shown, the second connecting member 2 includes a first connecting plate 22, a second connecting plate 23, and a third connecting plate 24. One side of the second connecting plate 23 is connected to the first connecting plate 22, and the other side of the second connecting plate 23 is connected to the third connecting plate 24. The first connecting plate 22, the second connecting plate 23, and the third connecting plate 24 form a U-shaped structure. At least a portion of the first connecting member 1 is disposed within the U-shaped structure, which not only provides assembly space for the first connecting member 1, but also facilitates the adjustment of the rotation angle of the second connecting member 2 relative to the first connecting member 1, thus avoiding structural interference problems caused by space limitations.

[0046] More specifically, in this embodiment, the second connector 2 is sleeved on part of the outer peripheral wall (i.e., the U-shaped structure) of the first connector 1, thereby enhancing the connection stability between the first connector 1 and the second connector 2, so that the first connector 1 is placed between the first connecting plate 22 and the third connecting plate 24, which can protect the first connector 1 and prevent it from being damaged.

[0047] Specifically, the adjustment mechanism 3 includes a first guide channel 12 disposed on the first connector 1 and a second guide channel 21 disposed on the second connector 2. The center line of the first guide channel 12 along the length direction is set at an angle to the center line of the second guide channel 21 along the length direction. The driven member 32 is slidably engaged with both the first guide channel 12 and the second guide channel 21, thereby guiding the driven member 32 to move along a predetermined trajectory to achieve precise angle adjustment and avoid adjustment accuracy problems due to inaccurate guidance.

[0048] More specifically, in this embodiment, the driven component 32 is an adjusting pin. One end of the adjusting pin is limited to the outside of the second connecting member 2, and the other end passes through the first guide channel 12 and the second guide channel 21, and is threaded to a nut. The nut stops on the outside of the second connecting member 2, and an open retaining ring is provided between the nut and the second connecting member 2 to ensure that the adjusting pin remains stable and does not loosen during movement. Moreover, through the dual limiting effect of the nut and the open retaining ring, the adjusting pin can slide smoothly within the first guide channel 12 and the second guide channel 21, while avoiding axial displacement caused by vibration or external force, thereby ensuring the accuracy and reliability of angle adjustment.

[0049] In addition, in other embodiments, the driven component 32 may also adopt a structure such as a pin or a screw. The specific structure of the driven component 32 is not limited here, as long as it can achieve the above-mentioned functions.

[0050] Specifically, the driving member 31 and the driven member 32 are threaded together, so that when the driving member 31 rotates, the driven member 32 moves along the defined direction of the first guide channel 12 and the second guide channel 21. By converting the rotational motion of the driving member 31 into the linear motion of the driven member 32, precise and stable adjustment is achieved.

[0051] More specifically, such as Figure 2 and Figure 3 As shown, the drive component 31 includes a screw, and the adjusting shaft pin is provided with a threaded hole 321. The screw is threadedly connected to the threaded hole 321. When the screw rotates, it can drive the adjusting shaft pin to slide in the first guide channel 12. That is, through the cooperation between the screw and the threaded hole 321, precise force transmission and motion control can be achieved, making angle adjustment easier and more convenient, and avoiding the difficulty of manual adjustment by the user.

[0052] In addition, in other embodiments, the driving element 31 may also be a linear motor or a cylinder, as long as it can drive the driven element 32 to slide in the first guide channel 12. The specific structure of the driving element 31 is not limited here.

[0053] Specifically, the movement trajectory of the driven member 32 along the first guide channel 12 and the movement trajectory of the driven member 32 along the second guide channel 21 are both straight lines, which helps to improve the smoothness and accuracy of the rotation of the second connecting member 2.

[0054] Specifically, such as Figures 1-3 As shown, the tilt adjustment assembly 4 includes two sliding structures 41. The sliding structures 41 are disposed on the first connecting member 1 and the second connecting member 2, and are used to guide and restrict the rotational movement of the second connecting member 2. The two sliding structures 41 are disposed on the same side of the adjustment mechanism 3, and the two sliding structures 41 are arranged vertically and horizontally. This arrangement can effectively guide the movement trajectory of the second connecting member 2, while limiting the movement range of the second connecting member 2, ensuring the smoothness and reliability of the rotation process, and avoiding structural damage or instability caused by excessive movement range.

[0055] More specifically, the sliding structure 41 includes a sliding channel 411, a connecting hole 412, and a connecting shaft 413. One of the sliding channel 411 and the connecting hole 412 is disposed on the first connecting member 1, and the other of the sliding channel 411 and the connecting hole 412 is disposed on the second connecting member 2. The connecting shaft 413 connects the sliding channel 411 and the connecting hole 412 (that is, the connecting shaft 413 passes through the sliding channel 411 and the connecting hole 412, and the connecting shaft 413 is slidably engaged with the sliding channel 411). The connecting shaft 413 is slidably engaged in the sliding channel 411. Since the connecting shaft 413 is connected to the second connecting member 2 through the sliding channel 411 or the connecting hole 412, when the second connecting member 2 moves relative to the first connecting member 1, the sliding engagement of the connecting shaft 413 with the sliding channel 411 guides and restricts the rotational movement of the second connecting member 2.

[0056] More specifically, in this embodiment, the first connecting member 1 has a sliding channel 411, and the first connecting plate 22 and the second connecting plate 23 of the second connecting member 2 have connecting holes 412. The connecting shaft 413 is a long screw, which passes through the connecting hole 412 and the sliding channel 411. One end of the long screw is limited to the outside of the second connecting member 2, and the other end of the long screw is threaded to a nut. The nut is limited and stopped on the outside of the second connecting member 2 to prevent the long screw from loosening or falling off during sliding, thereby further enhancing the stability of the overall structure. Since the long screw is slidably disposed in the sliding channel 411, when the driving member 31 and the driven member 32 drive the second connecting member 2 to rotate relative to the first connecting member 1, the sliding engagement between the long screw and the sliding channel 411 allows the second connecting member 2 to slide smoothly relative to the first connecting member 1.

[0057] It should be noted that in other embodiments, the sliding channel 411 is disposed on the second connector 2, and the connecting hole 412 is opened on the first connector 1. The specific position of the above structure is not limited here, as long as the above functions can be achieved.

[0058] Specifically, the sliding channel 411 is a straight through hole or an arc-shaped hole, which allows the operator to select the appropriate shape of the sliding channel 411 according to different adjustment needs, so as to meet the angle adjustment needs of the second connector 2.

[0059] More specifically, in this embodiment, the sliding channel 411 includes a first arc-shaped slide 4111 and a second arc-shaped slide 4112. Two connecting shafts 413 are provided, and the two connecting shafts 413 are slidably disposed on the first arc-shaped slide 4111 and the second arc-shaped slide 4112 in a one-to-one correspondence. The center of the first arc-shaped slide 4111 and the center of the second arc-shaped slide 4112 are both located on the side close to the adjusting mechanism 3. Through the synergistic effect of the two connecting shafts 413, the second connecting member 2 can be adjusted more smoothly and precisely.

[0060] It is understandable that, corresponding to the two connecting shafts 413, both the first connecting plate 22 and the third connecting plate 24 have two connecting holes 412 spaced apart in the vertical direction. One connecting shaft 413 passes through the upper connecting hole 412 and the first arc-shaped slide rail 4111 on the first connecting plate 22 and the third connecting plate 24, while the other connecting shaft 413 passes through the upper connecting hole 412 and the second arc-shaped slide rail 4112 on the first connecting plate 22 and the third connecting plate 24. This allows the two connecting shafts 413 to move independently within their respective slide rails without interfering with each other. Moreover, the spaced arrangement of the two connecting holes 412 ensures smoother movement of the second connecting member 2.

[0061] In addition, the first arc-shaped slide 4111 extends arc-shaped along the first axis, and the second arc-shaped slide 4112 extends arc-shaped along the second axis. Both the first axis and the second axis are parallel to the rotation axis of the second connector 2 relative to the first connector 1, which can ensure that the second connector 2 always maintains a stable motion trajectory during rotation and avoid the second connector 2 from getting stuck or unstable.

[0062] Specifically, such as Figures 1-4 As shown, the adjustment mechanism 3 also includes an adjustment knob 34, which is detachably connected to one end of the drive member 31. The adjustment knob 34 is used to drive the drive member 31 to rotate relative to the first connecting member 1. The user can manually rotate the adjustment knob 34 to achieve the rotation of the drive member 31, thereby driving the driven member 32 to move to achieve angle adjustment, which improves the convenience of operation.

[0063] Specifically, such as Figures 1-5As shown, the first connecting member 1 includes a fixing part 13, which has a stepped hole 131. One end of the driving member 31 passes through the stepped hole 131 and is connected to the adjusting knob 34. The limiting part 311 of the driving member 31 is disposed in the stepped hole 131 and is disposed on both sides of the fixing part 13 with the adjusting knob 34. This improves the installation stability between the driving member 31 and the fixing part 13 and avoids the failure of the adjusting mechanism 3 due to the loosening or displacement of the driving member 31.

[0064] More specifically, the adjustment mechanism 3 also includes a cover plate 35, which is detachably connected to the fixing part 13 and seals the limiting part 311 in the stepped hole 131, thereby further enhancing the structural stability of the adjustment mechanism 3 and preventing the driving part 31 from loosening or falling off during use.

[0065] More specifically, in this embodiment, the fixing part 13 is a fixing block, and the fixing block has a through stepped hole 131. One end of the screw of the driving member 31 passes through the stepped hole 131 and is detachably connected to the adjusting knob 34 by a pin. The other end of the screw passes through the cover plate 35 and has a threaded section for threaded connection to the driven member 32. Moreover, the middle part of the screw has a protrusion (i.e., a limiting part 311) around its circumference. The protrusion is limited in the stepped hole 131 by the cover plate 35, ensuring stable installation between the screw and the fixing block. Furthermore, the limiting effect of the protrusion prevents the screw from axially displacing during movement, thereby ensuring the accuracy and reliability of the adjusting mechanism 3 and avoiding adjustment errors caused by screw loosening.

[0066] Specifically, the first connector 1 further includes a fixing plate 14, at least a portion of which is assembled into the second connector 2, allowing the second connector 2 to rotate relative to the fixing plate 14. Furthermore, the fixing part 13 is detachably connected to the fixing plate 14 by screws for easy disassembly and maintenance.

[0067] The specific working process of the angle adjustment device is explained below:

[0068] First, the user manually rotates the adjustment knob 34 to drive the drive component 31 to rotate. Since the drive component 31 and the driven component 32 are threaded together, the driven component 32 achieves linear motion within the first guide channel 12 and the second guide channel 21. By sliding the driven component 32 within the first guide channel 12 and the second guide channel 21, the second connecting component 2 is pushed to rotate relative to the first connecting component 1. At this time, the up-and-down tilt adjustment component 4 further guides and restricts the rotational movement of the second connecting component 2. Since one connecting shaft 413 passes through the connecting hole 412 near the top on the first connecting plate 22 and the third connecting plate 24, and the first arc-shaped slide rail 4111, the other connecting shaft... The connecting holes 412 and the second arc-shaped slide rail 4112 on the first connecting plate 22 and the third connecting plate 24 are 413. The two connecting shafts 413 slide independently on the first arc-shaped slide rail 4111 and the second arc-shaped slide rail 4112 in a one-to-one correspondence, thereby guiding and restricting the rotation of the second connecting member 2. Moreover, the first arc-shaped slide rail 4111 extends arc-shaped along the first axis, and the second arc-shaped slide rail 4112 extends arc-shaped along the second axis. The first axis and the second axis are both parallel to the rotation axis of the second connecting member 2 relative to the first connecting member 1, so that the second connecting member 2 remains stable during rotation, thereby achieving precise and stable angle adjustment.

[0069] like Figures 1-7 As shown, this embodiment also provides a screen bracket, which includes a mounting component 100, a support component 200, and an angle adjustment device. The support component 200 is connected to the mounting component 100 via a second connector 2, and the angle adjustment device is used to adjust the pitch angle of the support component 200 relative to the mounting component 100. This allows for stable and precise adjustment of the screen pitch angle, resulting in higher reliability.

[0070] It should be noted that the mounting component 100 is used for mounting on the work surface, and the support component 200 is used to connect the screen, so that the screen is connected to the mounting component 100 via an angle adjustment device. This allows the tilt angle of the support component 200 relative to the mounting component 100 to be adjusted via the angle adjustment device, thereby achieving stable and precise adjustment of the screen's tilt angle. Furthermore, those skilled in the art are familiar with the specific structure and working principle of the mounting component 100 and the support component 200, and will not elaborate further here.

[0071] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
