Description

Technical Field

[0001] This utility model belongs to the field of computer accessories technology, specifically relating to a computer stand. Background Technology

[0002] In modern office and home environments, computer monitors are used extremely frequently as essential information display devices. However, traditional computer stand designs often lack flexibility and cannot meet users' needs for adjusting viewing angles. Specifically, traditional stands often only offer limited angle adjustment functions, making it difficult to achieve full-range viewing angle adjustment. This can lead to neck and eye fatigue during prolonged use, affecting work efficiency and health.

[0003] To improve the comfort and flexibility of computer monitors, some improved computer stands have emerged on the market. These stands increase the adjustability of the monitor by introducing rotating components. However, some stands only allow rotation in a single direction (such as horizontal or vertical) and cannot support simultaneous multi-directional free adjustment. This forces users to frequently adjust their posture to adapt to the screen angle during actual use. Some stands, while having rotation capabilities, lack effective limiting devices, making them prone to loosening or slippage during use, resulting in unstable screen position and affecting the user experience.

[0004] Chinese Patent No. CN222687703U discloses a computer stand, including a base and a support column. A support arm that moves along the height of the support column is mounted on the support arm. A support arm connector is mounted on the support arm connector, and a connecting frame is mounted on the connecting frame. A sheet metal connector for mounting on a computer screen is mounted on the connecting frame. The sheet metal connector has an assembly base surface with a locking unit. The connecting frame has an assembly mating surface that contacts the assembly base surface. A locking node is provided on the assembly mating surface to define the final assembly position of the sheet metal connector on the connecting frame. The locking node has a first guide channel, a second guide channel, and a third guide channel on the assembly mating surface to guide the locking unit to the locking node via a first assembly direction, a second assembly direction, and a third assembly direction. The beneficial effect of this invention is that it achieves a tool-free and parts-free operation mode for assembling the stand and computer screen, suitable for rapid and convenient assembly. However, the support arm of the above-mentioned device only moves along the height of the support column, and cannot achieve multi-degree-of-freedom adjustment of horizontal rotation or pitch angle. Therefore, it is urgent for those skilled in the art to solve the above-mentioned technical problems. Summary of the Invention

[0005] The present invention aims to solve the problem that in the prior art, the support arm of the above-mentioned device only moves along the height of the support column, and cannot achieve multi-degree-of-freedom adjustment of horizontal rotation or pitch angle.

[0006] The technical solutions adopted in this utility model are as follows:

[0007] A computer stand includes a support base for supporting the entire device, a rotating component mounted on the support base, and a connecting base mounted on the end of the rotating component;

[0008] The rotating assembly includes a housing, a mounting base, a connecting base, a connecting plate, a limiting plate, and a damping shaft; the damping shaft is rotatably mounted at both ends of the housing, and a preloaded torsion spring is installed inside the damping shaft;

[0009] The mounting base is installed inside the housing, and the limiting plate is installed on the inner side of the mounting base. The two ends of the limiting plate are outwardly protruding arc-shaped structures. The damping shaft is equipped with an inwardly concave arc-shaped structure that matches the limiting plate. The connecting seat at the front end of the housing is connected to the connecting plate, and the connecting plate is equipped with a rotating shaft for connecting to a computer display screen.

[0010] By adopting the above technical solution, the display screen can rotate freely in the vertical direction through the cooperation of the damping shaft and the housing. The pre-tightened torsion spring inside the damping shaft provides stable damping force. Combined with the arc-shaped structure of the limiting plate and the shaft, it ensures that the display screen maintains stable positioning at any angle, avoiding slippage or displacement caused by gravity or external force. The housing adopts an H-shaped structure, which enhances the rigidity and bending resistance of the bracket, effectively disperses the force, and improves the overall stability. It is especially suitable for the load-bearing requirements of large-size display screens. The aluminum alloy reinforcing plate inside the support base further optimizes the structural strength, reduces the risk of deformation after long-term use, and extends the service life. All angle and position adjustments can be completed by manually pushing lightly without additional tools or complicated operations, improving the user experience. The arc-shaped protrusion of the limiting plate and the groove structure of the damping shaft form a physical limit to prevent damage to components caused by excessive rotation, while ensuring that the rotation range is controllable.

[0011] Furthermore, the housing has an H-shaped structure, and the damping shaft is rotatably mounted at both ends of the housing;

[0012] The damping shafts at both the front and rear ends of the housing are mounted in the connecting seat.

[0013] By adopting the above technical solution, the H-shaped structure significantly improves the bending and torsional resistance of the shell through its horizontal and vertical support frames. This design allows the bracket to effectively distribute the force when bearing the weight of the display screen, reducing the risk of shell deformation or bending. It is especially suitable for the load-bearing requirements of large-size or high-resolution displays, ensuring uniform force distribution and avoiding structural failure caused by local stress concentration. The damping shafts at both ends of the shell are respectively installed in the end connectors, enabling the rotating components to achieve the following: the pitch angle of the display screen can be adjusted by connecting the end damping shaft to the support base, and the horizontal rotation of the display screen can be achieved by linking the end damping shaft to the connecting plate. The pre-tensioned torsion spring inside the damping shaft provides stable damping force, which, together with the limiting structure of the shell and the connecting base, ensures that the display screen remains stably positioned at any angle, avoiding slippage or shaking caused by gravity or external forces.

[0014] Furthermore, a positioning seat is provided between the horizontal protective housing and the horizontal rotating shaft. The positioning seat is fixed to the support plate by a connector, and the connector is fixed inside the support plate by screws.

[0015] By adopting the above technical solution, the positioning seat, as an intermediate fixed structure, can precisely constrain the axial position of the horizontal rotating shaft, preventing axial displacement due to external forces or vibrations during horizontal rotation. The screw fastening effectively prevents loosening of the positioning seat due to vibration or external forces during long-term use, thus ensuring a reliable connection between the rotating shaft and the horizontal protective housing. The design of the positioning seat provides a clear installation benchmark for the horizontal rotating shaft, ensuring that its concentricity and perpendicularity with the horizontal protective housing meet design requirements. This precise positioning reduces rotational jamming or abnormal noise problems caused by assembly errors, improving overall mechanical performance. The connecting parts are directly fixed inside the support plate with screws, allowing for quick connection between the positioning seat and the support plate without complex tools or additional adjustments. This modular design not only improves production efficiency but also facilitates later maintenance or component replacement for users.

[0016] Furthermore, the connecting seat at the tail end of the housing is installed inside the support seat by screws, and the support seat is also provided with a reinforcing plate adapted to the support seat, the reinforcing plate being made of aluminum alloy.

[0017] By adopting the above technical solution, the high strength and lightweight properties of aluminum alloy material can significantly improve the rigidity of the support base. By embedding a matching aluminum alloy reinforcing plate inside the support base, the load transmitted by the connecting seat at the rear end of the shell can be effectively distributed, preventing the support base from bending, deforming, or breaking due to long-term load. The connecting seat is directly installed inside the support base with screws, rather than surface clips or welding, avoiding the risk of loosening caused by vibration or external force in traditional brackets.

[0018] Furthermore, the limiting plate is installed inside the mounting base, and the two ends of the mounting base are respectively fitted onto the two damping shafts.

[0019] By adopting the above technical solution, the mounting base is fitted onto two damping shafts at both ends, forming a stable dual-axis support structure. This design significantly improves the bending and torsional resistance of the bracket by having the two damping shafts jointly bear the weight and rotational inertia of the display screen. The limiting plate is embedded inside the mounting base, and its arc-shaped protrusion forms a physical limit with the groove structure of the damping shaft, preventing axial displacement or radial slippage of the mounting base during rotation, thus avoiding display screen shaking or positioning failure due to displacement. Pre-tensioned torsion springs are installed inside the damping shafts at both ends of the mounting base, providing uniform damping force through dual-axis linkage. This design allows the display screen to be stably positioned at any angle.

[0020] Furthermore, the connecting seat located at the first end of the housing is connected to the connecting plate by screws, and the rotating shaft is rotatably mounted on the connecting plate.

[0021] By adopting the above technical solution, the rigid support with screw connections, where the connecting seat and connecting plate are fixed by screws, utilizes the high load-bearing capacity and shear resistance of threaded connections to ensure the stability of the rotating shaft during horizontal rotation. This design is particularly suitable for large-size displays or high-load scenarios, preventing loosening of connections or structural deformation due to torque during rotation. The connecting plate, as the load-bearing base of the rotating shaft, is fixed to the connecting seat at multiple points with screws, evenly distributing the radial force generated by rotation to the front end of the housing, reducing local stress concentration. This structural optimization extends the service life of the bracket, especially under frequent rotation or long-term use.

[0022] Furthermore, the damping shaft is rotatably mounted in the connecting seat, and the left and right ends of the connecting seat are equipped with limiting protrusions, and the two ends of the mounting seat are provided with limiting grooves that are adapted to the limiting protrusions.

[0023] By adopting the above technical solution, the limiting protrusions at both ends of the connector and the limiting groove of the mounting base form a physical limiting structure, which strictly limits the rotation range of the damping shaft. The damping force of the damping shaft, in conjunction with the limiting structure, not only ensures a smooth feel for the user when adjusting the angle, but also completely prevents excessive rotation at the extreme position through physical blocking, avoiding damage to components caused by external impact. After the limiting protrusions are embedded in the limiting groove of the mounting base, the bending and torsional resistance of the connector and the mounting base is significantly improved.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model achieves stable positioning of the display screen after multi-directional free adjustment by combining the arc structure of the damping rotating shaft and the limiting plate with the synergistic effect of the H-shaped shell and the pre-tightening torsion spring. It solves the problems of limited adjustment and easy positioning deviation caused by the single structure of traditional brackets, and meets the user's needs for flexible adjustment of the display screen in multiple angles such as tilt and horizontal rotation.

[0026] 2. This utility model significantly improves the overall rigidity and deformation resistance of the bracket through the combination design of H-shaped shell and aluminum alloy reinforcing plate, ensuring the structural stability of the large-size display screen when bearing weight. At the same time, the dual-axis linkage of the damping shaft and the rigid limiting of the limiting protrusion and groove effectively prevent damage to components caused by external impact or long-term use.

[0027] 3. This utility model adopts modular assembly and rigid screw connection, which simplifies the bracket assembly process, reduces maintenance costs, and through the dynamic balance design of pre-tightened torsion spring and damping shaft, users can complete the angle adjustment with just a light push, without additional tools or complicated operations, greatly optimizing the user experience.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific preferred embodiments.

[0037] In the description of this utility model, it should be understood that the terms "left side," "right side," "upper part," "lower part," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of this utility model. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the protection scope of this utility model.

[0038] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As can be seen, this utility model discloses a computer stand. The connection and positional relationship of the components of this computer stand are as follows: the support base 10 serves as the base structure, and an aluminum alloy reinforcing plate 11 is embedded inside it. It is fixed to the connecting seat 23 at the tail end of the rotating component 20 by screws 30; the tail end of the H-shaped housing 21 of the rotating component 20 is connected to the support base 10 through a damping shaft 25, and the head end is hinged to the connecting seat 23 through another damping shaft 25, forming a dual-axis linkage structure; a mounting seat 22 is installed inside the H-shaped housing 21, and the two ends of the mounting seat 22 are respectively fitted onto the two damping shafts 25 at the tail end and the head end, forming a dual-axis linkage structure. The system is supported by two axes, and a limiting plate 26 is fixed inside the mounting base 22. The limiting plate 26 has outwardly protruding arc-shaped structures at both ends, which are adapted to the inwardly concave arc-shaped structure on the surface of the damping shaft 25. The connecting base 23 is installed at the head end of the H-shaped housing 21 and is rigidly connected to the connecting plate 24 by screws 30. A rotating shaft 241 is installed at the end of the connecting plate 24 for connecting the display screen and enabling free horizontal rotation. In addition, the connecting base 23 has limiting protrusions 231 on both sides, which cooperate with the limiting grooves 221 at both ends of the mounting base 22 to physically limit the rotation angle range of the damping shaft 25. All components are tightly fitted together by screws 30, the damping shaft 25, and the adapted arc-shaped structures to achieve multi-directional adjustment and precise positioning of vertical pitch and horizontal rotation.

[0039] In one embodiment, such as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this device achieves stable positioning after rotation through the synergistic action of the damping shaft 25, the limiting plate 26, and the pre-tensioning torsion spring, combined with the H-shaped housing 21. The convex arc shape of the limiting plate 26 and the concave arc shape of the damping shaft 25 form complementary shapes. During rotation, friction is generated through the contact of the arc surfaces. The pre-tensioning torsion spring is installed inside the damping shaft 25, and the pre-tensioning force increases the normal pressure on the contact surface, thereby increasing the friction. When the display screen rotates to the target angle, the friction is sufficient to counteract the display screen's own weight or external force disturbance, achieving self-locking under stepless adjustment. The cooperation between the limiting protrusion 231 and the limiting groove 221 forms a rigid limit, strictly constraining the rotation range of the damping shaft 25.

[0040] In one embodiment, by adding an indexing groove to the convex arc surface of the limiting plate 26, and cooperating with the concave arc surface of the damping shaft 25 to form a graded locking, the H-shaped housing 21 distributes the load of the display screen through the horizontal and vertical frames, avoiding deformation caused by uniaxial stress concentration.

[0041] In one embodiment, the aluminum alloy reinforcing plate 11 is embedded inside the support base 10 to improve the base's bending resistance and prevent the support base from deforming after long-term use. The mounting base 22 is respectively fitted onto two damping rotating shafts 25 at both ends, and the torque is balanced by the synchronous rotation of the two shafts to reduce the risk of single-shaft overload.

[0042] Working principle: The outward convex arc structure at both ends of the limiting plate 26 and the inward concave arc structure on the surface of the damping shaft 25 form a complementary shape. When the user adjusts the tilt angle of the display screen, the arc surfaces fit together to generate a progressive friction force, the magnitude of which is determined by the preload of the preload torsion spring. A pre-tensioned torsion spring is installed inside the damping shaft 25. Adjusting the pre-tension increases the normal pressure on the contact surface, thereby increasing friction and ensuring the display screen can stably stop at any angle with stepless adjustment. The display screen is hinged to the connecting plate 24 via a rotating shaft 241. The friction of the rotating shaft 241 is indirectly transmitted through the damping shaft 25. Combined with the rigid limiting of the limiting protrusion 231 and the limiting groove 221, the arc-shaped contact surface between the limiting plate 26 and the damping shaft 25 generates friction during rotation, dynamically adapting to different display screen weights and ensuring self-locking reliability. A dividing groove is added to the convex arc surface of the limiting plate 26, forming a segmented engagement with the concave arc surface of the damping shaft 25. When the display screen rotates to its limit angle, the limiting protrusion 231 embeds into the limiting groove 221, completely limiting the rotation range through physical blocking and preventing structural damage caused by external impact. The H-shaped housing 21 distributes the display screen load through horizontal and vertical frames, avoiding deformation or breakage caused by uniaxial stress concentration. The two ends of the base 22 are respectively fitted onto the two damping shafts 25 at the beginning and end, forming a dual-axis linkage structure. The aluminum alloy reinforcing plate embedded inside the support base 10 is fixed to the support base by laser welding, which significantly improves the bending resistance of the base and prevents plastic deformation after long-term use. When in use, gently push the display screen to overcome the friction of the damping shaft 25. The arc-shaped contact surface slides smoothly to the target angle and automatically locks. Hold the display screen and rotate it horizontally. The damping force of the rotating shaft 241 ensures smooth adjustment. The modular design screw 30 connection supports quick disassembly, which is convenient for cleaning or replacing parts such as pre-tightened torsion springs. The vertical pitch stepless self-locking combined with the horizontal rotation limit meets the needs of multiple scenarios. The combination of friction and mechanical limit ensures both smooth operation and anti-interference ability. The H-shaped shell 21, the damping shaft 25 support, and the aluminum alloy reinforcing plate 26 work together to improve the structural rigidity. This device achieves lightweight, high-reliability multi-degree-of-freedom adjustment function while ensuring stable positioning of the display screen.

[0043] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
