Description

Technical Field

[0001] This application relates to the field of monitor bracket technology, and more specifically, to an adjustable-angle smart display bracket. Background Technology

[0002] With the widespread use of computers, LCD monitors, and smart interactive screens in offices, education, healthcare, and exhibitions, display stands have become essential accessories for improving ergonomics and space utilization. Existing stands are mostly fixed or have a simple tilt angle, resulting in limited adjustment range, inaccurate positioning, and poor stability. While some high-end products can achieve angle and height adjustment, their complex structures, cumbersome operation, and inconvenient maintenance make them difficult to maintain.

[0003] Chinese Patent Publication No. CN213394494U describes a device that "has a hanging block on top of the mounting base, and a hook on the hanging block. The hook can move along the length of the hanging block. The hook is connected to a mounting bracket, and the mounting bracket has several mounting slots for fixing the display. The display is fixed by bolts that fit into the mounting slots. That is, the display, the hook mounting bracket, and the hook are integrated. By changing the fit of different hooks and the hanging block, the height (vertical) of the display can be adjusted." It can be seen that the bracket for adjusting the angle of a large display still has the problems of complex structure and cumbersome operation. Utility Model Content

[0004] The technical problem this application aims to solve is that the bracket for adjusting the angle of a large display is structurally complex and cumbersome to operate.

[0005] To address the aforementioned technical problems, this application provides an adjustable-angle smart display stand, employing the following technical solution:

[0006] Includes a base, placement components, support arms, and connecting components;

[0007] The base is provided with a sliding groove, and a plurality of arc-shaped notches are provided at equal intervals on one side of the sliding groove;

[0008] The first end of the support arm is hinged to the placement component, and the second end of the support arm is installed in the slide groove through the connecting component. The connecting component drives the second end of the support arm to move in the slide groove, and selects any of the notches to fix it, so as to adjust the height of the support arm and the angle of the bracket.

[0009] Furthermore, the base is provided with a first limiting plate and a second limiting plate;

[0010] The first limiting plate and the second limiting plate are both provided with the sliding groove, and the second end of the support arm is connected to the first limiting plate and the second limiting plate through the connecting assembly.

[0011] Furthermore, the second end of the support arm is provided with a hollow structure having the same diameter as the notch;

[0012] The connecting component is installed inside the slide groove through the hollow structure.

[0013] Furthermore, the connecting assembly includes an adjusting rod and a fixing member;

[0014] One end of the adjusting rod passes through the slide groove and the hollow structure, and the fixing member is fixedly installed on one end of the adjusting rod.

[0015] Furthermore, the placement assembly includes a first housing, a second housing, and a fixed shaft;

[0016] The first end of the first housing is hinged to the support arm, and the second end of the first housing is hinged to the base;

[0017] The second housing is disposed inside the first housing, and the first housing and the second housing are connected by at least two of the fixed shafts.

[0018] Furthermore, the placement assembly also includes an elastic element;

[0019] The elastic element is installed between the two fixed shafts.

[0020] Furthermore, the first housing is provided with a first slot, and the second housing is provided with a second slot. The first slot and the second slot are arranged opposite to each other, and the external display is mounted on the bracket through the first slot and the second slot.

[0021] Furthermore, the groove is configured to be arc-shaped.

[0022] Furthermore, the support arm is configured to be arc-shaped.

[0023] Furthermore, at least two supports are provided.

[0024] Compared with the prior art, the embodiments of this application have the following main advantages:

[0025] This application achieves stable and stepped adjustment of the support arm's height and angle by setting an arc-shaped groove on the base and opening arc-shaped notches at equal intervals, and by having a connecting component guide along the groove and position it at the notch. This structure is simple and highly mechanized, significantly reducing the structural complexity and manufacturing cost of large-size, heavy-weight monitor stands. Simultaneously, the engagement positioning of the notch on one side of the groove provides clear discrete positions, ensuring repeatability and positioning accuracy. The cooperation between the hinged placement component and the groove guide makes the adjustment process smooth and the force path clear. The eccentric torque generated by the monitor can be effectively transmitted and distributed to the base, thus meeting the safety and durability requirements of large monitors in multi-angle and multi-height usage scenarios. Furthermore, this structure facilitates assembly, maintenance, and mass production. Users can achieve quick manual adjustment and reliable locking, effectively solving the problems of complex structures and cumbersome operation in existing large monitor stands.

[0033] Embodiment 1 of the adjustable angle smart display stand of this application

[0034] like Figure 1 As shown, this application embodiment provides an adjustable angle smart display bracket, including a base 1, a placement component, a support arm 2, and a connecting component; the base 1 is provided with a slide groove 3, and a plurality of arc-shaped notches are provided at equal intervals on one side of the slide groove 3; the first end of the support arm 2 is hinged to the placement component, and the second end of the support arm 2 is installed in the slide groove 3 through the connecting component. The connecting component drives the second end of the support arm 2 to move in the slide groove 3, and any notch is selected for fixing to adjust the height of the support arm 2 and the angle of the bracket.

[0035] In this embodiment, the base 1 serves as a support component, with a groove 3 milled into it. A series of arc-shaped notches (the depth and radius of the notches match the curvature of the groove 3) are machined at equal intervals on the upper side of the groove 3. These notches are used for engagement of the connecting components. The placement component consists of a housing and a hinge shaft. The first end of the support arm 2 is connected to the placement component via the hinge shaft. The hinge shaft requires a mating hole, interference fit, or mating pin, and is secured with an elastic retaining ring to prevent loosening. The connecting component passes through the second end of the support arm 2 and engages with the groove 3, allowing the support arm 2 to slide under the guidance of the groove 3. The engagement point between the groove 3 and the connecting component can be configured with a low-friction bushing or bearing to ensure smooth movement. All bolts use self-locking washers or thread-locking adhesive to prevent loosening. Concentricity control and clearance tolerance are implemented at key mating points to ensure that there is no jamming or excessive clearance during adjustment. When in use, the user holds the support arm 2, allowing it to move along with the connecting assembly within the slide groove 3. When the desired height or right angle of the support arm 2 is reached, the adjusting rod 4 on the connecting assembly aligns and engages with the arc-shaped notch on one side of the slide groove 3. Then, the fixing part 5 (such as a knob nut or quick-lock) is tightened to lock the connecting assembly at the notch. For fine-tuning, the fixing part 5 can be loosened, moved slightly along the slide groove 3, and then re-fixed. Routine maintenance includes regularly lubricating the lining of the slide groove 3, checking for damage to the positioning notch, and checking the tightening torque of the hinge shaft and fasteners. This structure combines the height and angle adjustment mechanism of the support arm 2 with the arc-shaped positioning notch, ensuring smooth adjustment and improving positioning accuracy. The combination of the slide groove 3 and the arc-shaped notch allows the support arm 2 to withstand radial and axial loads at any positioning point, preventing loosening or sagging due to long-term use. The modular assembly method facilitates production and maintenance; the connecting assembly uses the adjusting rod 4 and the fixing part 5, resulting in a simple structure, low cost, and high reliability. For users, the adjustment is convenient and intuitive, and quick locking can be achieved without complicated tools.

[0036] In one embodiment, the base 1 is provided with a first limiting plate 11 and a second limiting plate 12; both the first limiting plate 11 and the second limiting plate 12 are provided with sliding grooves 3, and the second end of the support arm 2 is connected to the first limiting plate 11 and the second limiting plate 12 through a connecting component.

[0037] In this embodiment, two symmetrical or irregularly shaped limiting plates (first limiting plate 11 and second limiting plate 12) are provided on the base 1. The two limiting plates are arranged along the base 1 to form a parallel or concentric double sliding groove 3 structure to improve the stress stability of the support arm 2. Each limiting plate is integrally formed with the base 1. The second end of the support arm 2 is connected to the sliding grooves 3 on both sides through a connecting component. The connecting component can be a through rod type connecting member. Both ends are positioned and engaged with the arc-shaped notches in the two limiting plates through fixing members 5, forming a stable dual-axis guide point. To prevent lateral swaying, elastic shims or bearing clearance adjusting washers can also be provided on both sides of the connecting component for pre-tightening. During adjustment, the sliding grooves 3 on the two limiting plates simultaneously constrain the movement of the second end of the support arm 2. By moving the support arm 2, the connecting component slides synchronously in the double sliding grooves 3, selects the corresponding arc-shaped notches for engagement and positioning, and then applies force to lock the connection component, so that the support arm 2 is positioned on both sides simultaneously. The double-limiting plate and double-slide groove structure significantly improves the torsional and lateral force resistance of the support arm 2, distributing the eccentric torque generated by the display and avoiding torsional sway and fatigue damage caused by unilateral guidance. Simultaneous constraints on both sides ensure stability and consistent positioning during adjustment, improving product lifespan and safety. This structure also facilitates the support of large or heavy displays, as the force is dispersed between the two limiting plates, reducing stress concentration in individual components.

[0038] In one embodiment, the second end of the support arm 2 is provided with a hollow structure with the same diameter as the notch; the connecting component passes through the hollow structure and is installed in the groove 3.

[0039] In this embodiment, the second end of the support arm 2 is machined into a hollow cylindrical shape, with its inner diameter matching the diameter of the arc-shaped notch on the slide groove 3 or designed to be the same as the diameter of the connecting component, to ensure that the connecting component can pass through the hollow structure and directly engage with the notch during positioning. The hollow structure needs to have sufficient wall thickness to withstand bending moment and shear force, and a bushing or wear-resistant inner cylinder can be installed inside the hollow hole to reduce friction and wear. After the connecting component passes through the slide groove 3 of the first limiting plate 11 and the hollow structure, it enters the slide groove 3 of the second limiting plate 12. The fixing member 5 is coupled to the notch on the side of the slide groove 3 to achieve reliable locking. The hollow structure and the main body of the support arm 2 are set as an integral molding structure to reduce loosening. During assembly, the connecting component first passes through the slide groove 3 of the first limiting plate 11 into the hollow structure of the support arm 2, and then passes through the slide groove 3 of the second limiting plate 12 for fixing. When the user adjusts, when the support arm 2 moves to the target position, the hole of the hollow structure aligns with the notch of the slide groove 3, and the connecting component enters the notch through the hollow hole and is locked by the fixing member 5. If disassembly and replacement are required, first loosen the fastener 5 and pull the connecting assembly out of the hollow structure. Then, the support arm 2 can be removed from the slide 3 or its position adjusted. The introduction of the hollow structure simplifies the connection path and achieves more reliable positioning. The connecting assembly passes directly through the support arm 2 into the notch, reducing the influence of exposed parts and lateral torque, and improving positioning rigidity. The hollow structure also provides better assembly guidance, reduces the risk of misassembly, and facilitates on-site maintenance. Using wear-resistant bushings extends service life and reduces later maintenance costs. This design ensures strength while making the structure simpler, more reliable, and easier to assemble.

[0040] In one embodiment, the groove 3 is configured to be arc-shaped.

[0041] In this embodiment, the arc-shaped slide 3 is designed as an arc or a partial arc curve along the base 1. The center of the arc is concentric with the hinge point of the support arm 2 or eccentric according to the design to achieve a specific geometric relationship. During processing, the arc-shaped slide 3 must ensure continuous curvature and low surface roughness to reduce movement resistance and noise. An arc-shaped notch is machined on the side of the slide 3, and the notch matches the radius of curvature of the slide 3 to ensure that the connecting components are subjected to uniform force at any position. Wear-resistant rails can be installed inside the arc-shaped slide 3 to make movement smoother in heavy-load scenarios. Due to the curved geometry, the support arm 2 rotates along an arc path during adjustment, which can achieve coupling of angle change and height change. The user slides the support arm 2 along the arc path to the target position and engages the notch to lock it. By using the arc-shaped slide 3, a more natural ergonomic posture adjustment can be achieved. The tilt angle can be adjusted simultaneously while adjusting the height, improving the viewing experience. In addition, the arc trajectory helps to distribute the weight of the display to the base 1 through the curved geometry, reducing single-point stress and improving structural life.

[0042] In one embodiment, the support arm 2 is configured as an arc.

[0043] In this embodiment, the arc-shaped support arm 2 adopts a curved shape, and its curvature matches the arc shape of the slide 3 or the geometry of the placement component. The cross-sectional design of the support arm 2 needs to balance strength and weight, and is thickened in key stress areas. The arc-shaped support arm 2 is fitted with long-life bearings or bushings at the hinge. Due to the arc geometry, the feel and movement trajectory are smoother and more natural. When the user pulls or pushes the support arm 2 to adjust the height / angle, the direction of the force is consistent with the curvature of the support arm 2, which can effectively reduce the required operating force. During adjustment, it must be ensured that the center of curvature of the support arm 2 is positioned appropriately with the hinge to avoid the formation of unwanted torque or spin torque.

[0044] The curved support arm 2 brings multiple benefits in terms of mechanics and visuals. On the one hand, it can more effectively distribute bending moment and shear stress, reduce local stress concentration, thereby enhancing load-bearing capacity and extending service life. On the other hand, the curved design makes the adjustment action smoother and the user experience better.

[0045] In one embodiment, at least two supports are provided.

[0046] In this embodiment, at least two supports are used to share the load for large displays. When a single support is insufficient to support a large display, at least two supports can be used together. Multiple supports are connected by slots in the first housing 6 and the second housing 7 of each support's placement assembly to jointly mount a support plate, thereby mounting the large display onto the support plate. Using at least two supports expands applicability, enabling splicing, 3D displays, or distributed display layouts to meet complex applications such as professional displays, airport displays, control rooms, and trading halls. The multi-support design improves the system's scalability and modular maintainability; a single support failure can be replaced independently without affecting overall operation. Furthermore, the coordinated design of multiple supports enables stable support for larger screens or higher loads, improving safety and reliability.

[0047] Embodiment 2 of the adjustable angle smart display bracket of this application

[0048] like Figure 2 As shown, the connecting assembly includes an adjusting rod 4 and a fixing member 5; one end of the adjusting rod 4 passes through the slide groove 3 and the hollow structure, and the fixing member 5 is fixedly installed on one end of the adjusting rod 4.

[0049] In this embodiment, the connecting assembly consists of an axial adjusting rod 4 (which may have a handle or knob) and a fixing member 5 at one end. The diameter of the adjusting rod 4 matches the hollow structure and the inner bushing of the slide groove 3, with strict tolerance control. The rod end has a stop groove or threaded section for installing the fixing member 5 (such as a nut, locking ring, or quick-release buckle). The fixing member 5 can be a knob nut, a pawl-type quick-locking member, or a spring-loaded push-pull lock. After installation, the fixing member 5 provides axial or rotational locking for the adjusting rod 4. The entire connecting assembly should be designed for easy manual operation but prevent accidental loosening (e.g., with a self-locking nut or cam lock). The user moves and positions the support arm 2 within the slide groove 3 by rotating or pushing / pulling the adjusting rod 4: loosen the fixing member 5 (rotate the knob counterclockwise or press the quick lock), slide the support arm 2 to the selected position under moderate load, and then reset or tighten the fixing member 5 to complete the locking. If a pawl or spring-loaded buckle fixing member 5 is used, the user only needs to press the release button and slide; after release, the buckle automatically engages with the notch. The length and handle design of the adjustment lever 4 allow for one-handed operation, while the self-locking or self-braking characteristics of the fixing component 5 prevent loosening due to vibration. The combination of the adjustment lever 4 and the fixing component 5 makes the adjustment process intuitive, quick, and safe. Different types of fixing components 5 (knob, self-locking, ratchet) provide different levels of locking force and convenience depending on the usage scenario: manual knobs are preferred in office environments for comfort; ratchet or locking mechanisms can be used in industrial environments to prevent accidental operation. This design reduces assembly complexity and facilitates mass production (fewer parts, standardized components), while the self-locking structure improves safety by preventing the monitor from accidentally falling due to vibration or impact.

[0050] Embodiment 3 of the adjustable angle smart display bracket of this application

[0051] like Figure 2 As shown, the placement assembly includes a first housing 6, a second housing 7, and a fixed shaft 8; the first end of the first housing 6 is hinged to the support arm 2, and the second end of the first housing 6 is hinged to the base 1; the second housing 7 is disposed inside the first housing 6, and the first housing 6 and the second housing 7 are connected by at least two fixed shafts 8.

[0052] In this embodiment, the placement component is the core module that supports and adjusts the orientation of the display screen. The first housing 6 is the outer shell, with a hinge hole at the first end to engage with the hinge pin of the support arm 2, and a similar hinge structure at the second end to connect with the base 1, forming a double-hinge structure. The second housing 7 is placed inside the first housing 6 as an embedded adjustment component, and the two are connected by at least two fixed shafts 8. These fixed shafts 8 serve as connecting components, adjustment shafts, or rotation shafts. An appropriate gap is reserved between the first housing 6 and the second housing 7, and a limiting structure (such as a limiting groove or a stop) is provided to limit the relative rotation angle. During assembly, the second housing 7 is first placed into the first housing 6, at least two fixed shafts 8 are installed and locked, and then the hinge points connecting the hinge pin of the support arm 2 to the base 1 are installed. The hinges are tightened in sequence, and the tightness of each hinge point is checked. The relative movement between the first housing 6 and the second housing 7 is guided by the fixed shafts 8 and limited by the limiting structure to prevent excessive rotation. The dual-shell and multi-fixed-axis design allows for a wider range of attitude adjustments while improving load-bearing capacity and structural redundancy. Even if one fixed axis 8 becomes loose or partially stressed, the load can still be shared by the other fixed axes 8, increasing safety. The fitting structure of the inner and outer shells makes the adjustment movements smoother, and the multi-axis fixation ensures high repeatability and positioning accuracy, enhancing the user experience.

[0053] In one embodiment, the placement component further includes an elastic element; the elastic element is mounted between the fixed shafts 8.

[0054] In this embodiment, elastic elements (such as compression springs or torsion springs) are provided between two or more fixed axes 8. The size and stiffness of the elastic elements must match the weight range of the placed components and the desired return force. Anti-slip pads or positioning sleeves can be used between the elastic elements and the axes to prevent displacement, and protective sleeves are provided around them to prevent exposure and uneven force distribution. If a torsion spring is used, it can be assembled around the fixed axis 8 to directly provide return force or damping for the hinge action. The elastic elements play a role in assisting and damping in the placed components: when the user adjusts the monitor angle, the elastic elements provide a gradual feedback force, making the adjustment smoother and allowing it to slowly return to its original position or maintain the angle after release. During installation and debugging, the initial preload (preload) of the elastic elements needs to be measured to ensure that it will not be completely relaxed or overloaded within the normal operating angle range. The introduction of the elastic elements improves the adjustment feel, effectively buffering the inertia or external force generated during the movement of the support arm 2, allowing the user to achieve large angle adjustments with less force. The elastic preload can also automatically balance the support arm 2, keeping the monitor stable within a certain angle range without the need for frequent locking. For smart displays (touchscreen or sensor-based), elastic elements can also reduce the impact of external vibrations on the screen, improving touch accuracy and viewing stability.

[0055] In one embodiment, the first housing 6 is provided with a first slot 61, and the second housing 7 is provided with a second slot 71. The first slot 61 and the second slot 71 are arranged opposite to each other, and the external display is mounted on the bracket through the first slot 61 and the second slot 71.

[0056] In this embodiment, the first slot 61 and the second slot 71 are formed at opposite positions on the first and second outer shells, creating a snap-fit ​​and limiting structure. The slot shape can be rectangular, U-shaped, or stepped, and the slot dimensions should match the insert or flange (clearance tolerance control). The edges of the slots are rounded to reduce stress concentration. The structure of the first slot 61 and the second slot 71 provides access positions for large displays or mounting plates for display installation.
