Description
Technical Field
[0001] This utility model relates to the field of floating display technology, and in particular to a floating display that can rotate at multiple angles. Background Technology
[0002] With the popularization of IT products, people's lives and work are becoming increasingly inseparable from computers. LCD monitors are becoming more and more popular due to their low radiation, environmental friendliness, beautiful appearance, and small footprint. Currently, in order to provide people with a comfortable user environment, all monitors on the market are designed to be rotatable. People can adjust the monitor according to their sitting posture and other factors to find a comfortable usage state.
[0003] The current market generally uses a support scheme of brackets and hinges. Although this design can achieve multi-angle rotation and effectively save space, it has significant defects in practical applications. When traditional hinge structures bear the weight of the display screen for a long time, they are prone to mechanical loosening due to metal fatigue and wear of contact surfaces, which leads to a decrease in the rigidity of the support system. Especially when the display screen is heavy, the traditional single-point hinge structure is prone to structural deformation, causing the display screen to shift at an angle during rotation, or even tilting and settling. This decrease in mechanical stability not only affects the user's viewing experience, but may also cause the center of gravity of the device to shift, leading to the risk of tipping over and potential damage to precision electronic components. Utility Model Content
[0004] Therefore, it is necessary to address the problem that traditional hinged structures are prone to mechanical loosening due to metal fatigue and contact surface wear when subjected to the weight of the display screen over a long period of time, which leads to a decrease in the rigidity of the support system. Especially when the display screen is heavy, the traditional single-point hinged structure is prone to structural deformation, causing the display screen to shift at an angle during rotation, or even tilting and settling. To address this issue, a floating display screen that can rotate at multiple angles is needed.
[0005] A multi-angle rotatable floating display screen includes: a multi-angle adjustable robotic arm, a bracket is horizontally fixedly inserted above the multi-angle adjustable robotic arm, a first support rod is fixedly connected to one end of the bracket, a second support rod is hinged to one side of the first support rod, a support plate is fixedly connected to one side of the second support rod, and a display body is bolted to one side of the support plate.
[0006] The first support rod and the second support rod rotate horizontally, and the second support rod and the support plate rotate vertically up and down.
[0007] The guide rails are provided in four parts, each of which is located on one side of the outer wall of the support plate. Each of the four guide rails is slidably connected to a damping telescopic rod, and the end of the damping telescopic rod away from the guide rail is fixed to the first support rod.
[0008] In one embodiment, a fixing plate is provided at the connection between the bracket and the multi-angle adjustable robotic arm, and one end of the bracket is inserted into the interior of the multi-angle adjustable robotic arm.
[0009] In one embodiment, two limiting holes are formed inside both sides of the second support rod, and the two limiting holes are set at 90° apart.
[0010] In one embodiment, a connecting block is fixedly connected to one side of the outer wall of the support plate, and two pins are movably inserted into the interior of the second support rod. One of the pins is located at the connection between the connecting block and the second support rod, and the other pin is located at the connection between the first support rod and the second support rod.
[0011] In one embodiment, both ends of the damping telescopic rod are movably connected to spherical hinges, and a limiting plate is fixedly sleeved on the outer wall of the first support rod. One of the spherical hinges is fixed on one side of the outer wall of the limiting plate, and the other spherical hinge slides inside the guide rail.
[0012] In one embodiment, the four guide rails extend outwards around the second support rod as an axis, and the guide rails are detachably connected to the support plate.
[0013] In one embodiment, each of the four guide rails has two movably positioned limiting blocks inside, with the two limiting blocks sliding on either side of the spherical hinge.
[0014] In one embodiment, the limiting block has a threaded rod inside; the two ends of the threaded rod are engaged with plugs.
[0015] Beneficial effects
[0016] 1. The first support rod and the second support rod are connected by a hinge structure to achieve horizontal rotation, and the second support rod and the support plate are connected by a pin to achieve vertical rotation. The four damping telescopic rods provide dynamic support and damping buffer during the rotation of the display screen through the synergistic effect of the guide rail and the ball hinge. Finally, a display device with multi-directional rotation, angle locking and suspension shock absorption functions is formed, which greatly increases the stability and safety of the suspended display body during use.
[0017] 2. Two symmetrically arranged limiting holes are formed on both sides of the second support rod, with their axes orthogonally distributed at 90°. Each limiting hole has three annular grooves on its inner wall to accommodate O-ring seals. When the pin is inserted, the seal undergoes radial elastic deformation, forming an interference fit. This ensures the positioning accuracy of the pin and avoids wear caused by direct metal-to-metal contact. The two limiting holes correspond to the locking positions for horizontal and vertical rotation, respectively. This double limiting hole structure, in conjunction with the pin, allows the display screen to maintain its flexibility during multi-directional rotation while achieving precise locking of key angles through mechanical limiting. This effectively solves the angle shift problem caused by long-term use of traditional hinge structures. At the same time, the 90° orthogonal layout of the limiting holes and the distribution of the guide rails on the support plate form a spatial geometric correspondence, ensuring that the four damping telescopic rods maintain a symmetrical force state during rotation, further improving the mechanical stability of the overall structure.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0027] The following is combined with Figure 1 - Figure 5 This invention describes a multi-angle rotatable floating display screen.
[0028] In one embodiment, a multi-angle rotatable floating display screen includes: a multi-angle adjustable robotic arm 100 and guide rails 600. A bracket 101 is horizontally fixedly inserted above the multi-angle adjustable robotic arm 100. A first support rod 200 is fixedly connected to one end of the bracket 101. A second support rod 300 is hinged to one side of the first support rod 200. A support plate 400 is fixedly connected to one side of the second support rod 300. A display body 401 is bolted to one side of the support plate 400. The first support rod 200 and the second support rod 300 can rotate horizontally, while the second support rod 300 and the support plate 400 can rotate vertically up and down. Four guide rails 600 are provided, and each of the four guide rails 600 is located on one outer wall of the support plate 400. A damping telescopic rod 500 is slidably connected inside each of the four guide rails 600. The end of the damping telescopic rod 500 away from the guide rail 600 is fixed to the first support rod 200.
[0029] It should be noted that the multi-angle adjustment robotic arm 100 is generally composed of multiple support arms that are hinged to each other. The multi-angle adjustment robotic arm 100 realizes the height and position adjustment of the monitor body 401 through the hinge structure at the connection point, which greatly increases the flexibility of the monitor body 401 during use. The multi-angle adjustment robotic arm 100 is a relatively mature product in the existing technology. Choose the appropriate model according to the usage requirements. There will be no further details here.
[0030] In this embodiment, a connecting block 402 is fixedly provided on one side of the outer wall of the support plate 400 and is detachably connected to the display body 401 by bolts. Four detachable guide rails 600 are provided on the side of the support plate 400 near the second support rod 300, extending outward from the second support rod 300 as the axis. Damping telescopic rods 500 are slidably connected inside the four guide rails 600. Both ends of the damping telescopic rods 500 are movably connected to the limiting plate 201 and the guide rails 600 respectively through ball hinges 501. Two limiting blocks 601 are provided inside each guide rail 600 to limit the sliding range of the ball hinges 501 in both directions.
[0031] The first support rod 200 and the second support rod 300 are connected by a hinge structure to achieve horizontal rotation, and the second support rod 300 and the support plate 400 are connected by a pin 302 to achieve vertical rotation. The four damping telescopic rods 500 provide dynamic support and damping buffer during the rotation of the display screen through the synergistic effect of the guide rail 600 and the spherical hinge 501, ultimately forming a display device with multi-directional rotation, angle locking and suspension shock absorption functions.
[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a fixing plate is provided at the connection between the bracket 101 and the multi-angle adjustable robotic arm 100, and one end of the bracket 101 is inserted into the interior of the multi-angle adjustable robotic arm 100. Two limiting holes 301 are opened inside both sides of the second support rod 300, and the two limiting holes 301 are set at 90° between them.
[0033] In this embodiment, a stepped fixing plate structure is provided at the connection between the bracket 101 and the multi-angle adjustable robotic arm 100. A rigid connection is achieved by hexagonal bolts and corresponding threaded holes at the top of the multi-angle adjustable robotic arm 100. One end of the bracket 101 inserted into the multi-angle adjustable robotic arm 100 adopts a tapered fit structure, with an insertion depth of 2 / 3 of the total height of the multi-angle adjustable robotic arm 100. This design enables the bracket 101 to effectively resist rotational loosening when subjected to horizontal torque through the dual action of friction and mechanical engagement.
[0034] The second support rod 300 has two symmetrically opened limiting holes 301 on both sides, with their axes orthogonally distributed at 90°. Each limiting hole 301 has three annular grooves on its inner wall to accommodate the O-ring seal. When the pin 302 is inserted, the sealing ring undergoes radial elastic deformation to form an interference fit, which ensures the positioning accuracy of the pin 302 and avoids wear caused by direct metal contact. The two limiting holes 301 correspond to the locking positions for horizontal and vertical rotation, respectively.
[0035] The combination of this double limiting hole 301 structure and the pin 302 allows the display screen to maintain its flexibility during multi-directional rotation, while also achieving precise locking of key angles through mechanical limiting. This effectively solves the problem of angle displacement caused by long-term use of traditional hinge structures. At the same time, the 90° orthogonal layout of the limiting holes 301 and the distribution of the guide rails 600 of the support plate 400 form a spatial geometric correspondence, ensuring that the four damping telescopic rods 500 always maintain a symmetrical force state during rotation, further improving the mechanical stability of the overall structure.
[0036] like Figure 2 , Figure 3 and Figure 4As shown, a connecting block 402 is fixedly connected to one side of the outer wall of the support plate 400. Two pins 302 are movably inserted into the interior of the second support rod 300. One pin 302 is located at the connection between the connecting block 402 and the second support rod 300, and the other pin 302 is located at the connection between the first support rod 200 and the second support rod 300. Both ends of the damping telescopic rod 500 are movably connected to ball hinges 501. A limiting plate 201 is fixedly sleeved on the outer wall of the first support rod 200. One ball hinge 501 is fixed on one side of the outer wall of the limiting plate 201, and the other ball hinge 501 slides inside the guide rail 600.
[0037] In this embodiment, the connecting block 402 on one side of the outer wall of the support plate 400 is precision machined from high-strength aluminum alloy, and the surface is anodized to form a hard oxide layer. It is rigidly connected to the back plate of the display body 401 by four sets of stainless steel hexagonal bolts. The two pins 302 that are movably inserted inside the second support rod 300 are cylindrical structures with chrome-plated surfaces. One end is provided with an annular groove to accommodate an O-ring seal. When the pin 302 is inserted into the limiting hole 301, the seal is compressed to generate a certain interference, which ensures positioning accuracy and avoids metal friction and wear.
[0038] The spherical hinges 501 at both ends of the damping telescopic rod 500 are made of stainless steel, with the ball head polished. The hinge seat is inlaid with a self-lubricating copper sleeve, allowing a certain amount of multi-directional deflection and effectively releasing stress concentration during rotation. The limiting plate 201 on the outer wall of the first support rod 200 is fixed by laser welding to constrain the movement trajectory of the spherical hinge 501 and prevent the damping telescopic rod 500 from radially shifting during extension and retraction. The spherical hinge 501 inside the guide rail 600 is coated with a PTFE wear-resistant coating, forming a low-friction coefficient sliding pair with the inner wall of the guide rail 600, ensuring smooth and jam-free rotation. The four detachable guide rails 600 are fixed to the support plate 400 by countersunk bolts. Their cross-section is T-shaped, which ensures structural strength and facilitates quick disassembly and maintenance.
[0039] like Figure 2 , Figure 4 and Figure 5 As shown, four guide rails 600 extend outwards around the second support rod 300 as the axis, and the guide rails 600 and the support plate 400 are detachably connected. Each of the four guide rails 600 has two movably installed limiting blocks 601 inside. The two limiting blocks 601 slide on both sides of the spherical hinge 501, and the limiting blocks 601 have threaded rods 6011 inside. The two ends of the threaded rods 6011 are engaged with plugs.
[0040] In this embodiment, four guide rails 600 are radially symmetrically distributed around the second support rod 300. Their detachable design allows for quick assembly and disassembly via countersunk bolts and support plate 400, facilitating adjustment of the guide rail 600 length or replacement of telescopic rod assemblies with different damping coefficients according to the weight of the display. Two limiting blocks 601 are set inside each guide rail 600, forming an adjustable bidirectional mechanical stop through the meshing structure of threaded rod 6011 and plug. Rotating the threaded rod 6011 can drive the limiting block 601 to move axially along the guide rail 600, precisely controlling the maximum sliding displacement of the spherical hinge 501.
[0041] This design enables the display screen to have multi-level angle limiting functions. For example, it can set stepless limits within the horizontal rotation range. When the spherical hinge 501 slides to the limit block 601, the PTFE coating and the soft rubber pad on the end face of the plug form a buffer contact, which not only avoids metal collision noise, but also absorbs impact energy through elastic deformation. The four symmetrically distributed limit adjustment mechanisms and the damping characteristics of the damping telescopic rod 500 form a double guarantee, ensuring that the heavy display screen always maintains dynamic balance during rotation. This effectively solves the tilting and settlement problem caused by single-point force in traditional structures, and significantly improves the safety and durability of the equipment.
[0042] Working principle: When the user adjusts the screen angle, the first support rod 200 and the second support rod 300 achieve horizontal rotation through the hinge structure, and the second support rod 300 and the support plate 400 achieve vertical rotation through the connecting block 402. The four damping telescopic rods 500 extend and retract synchronously with the rotation.
[0043] The ball hinges 501 at both ends of the damping telescopic rod 500 slide within the guide rail 600, forming a low-friction sliding pair with the inner wall of the guide rail 600 through the PTFE coating, ensuring smooth operation. The threaded rod 6011 in the limit block 601 can adjust the sliding range, and together with the limit plate 201, it precisely controls the rotation angle and prevents radial deviation. When the target angle is reached, the O-ring is compressed to produce an interference fit through the multi-angle support of the pin 302 and the damping telescopic rod 500, thus achieving mechanical locking.
[0044] This design achieves multi-directional rotation through a dual-support rod hinge structure. Combining the dynamic buffering of the damping telescopic rod 500 with the geometric constraints of the guide rail 600, it ensures flexibility while solving the loosening problem of traditional hinge structures through mechanical limiting. The four symmetrically distributed damping telescopic rods 500 form a suspension support system, effectively dispersing the gravity of the display screen and avoiding tilting caused by single-point force. This enables precise control of horizontal and vertical rotation, ultimately resulting in a design that combines multi-angle adjustment with long-term stability.
