Description

Technical Field

[0001] This invention relates to the field of computer display technology, and more specifically to a multi-angle adjustable and stable support device for a computer display. Background Technology

[0002] In today's booming information technology engineering, computers have become indispensable tools for people's work, study, and life. As a key interface for human-computer interaction, the performance and user experience of computer monitors directly affect users' work efficiency and quality of life. With the rapid development of digital office, multimedia entertainment, and professional design, people's requirements for computer monitors are increasing. They not only expect high resolution and high refresh rates, but also place higher demands on the adjustability and stability of the monitors.

[0003] Traditional computer monitors have significant limitations in terms of angle adjustment. Most common monitors only offer simple tilt adjustment, and the adjustment range is very limited. In actual use, users often encounter various problems. For example, in office environments with complex lighting, when sunlight or lamplight shines directly on the screen, the inability to accurately adjust the monitor angle to avoid reflected light leads to severe glare, resulting in blurry display content. Users find it difficult to see the text and images on the screen, thus affecting work efficiency. For professionals engaged in graphic design, video editing, and other tasks requiring precise viewing angles, the single adjustment method of traditional monitors cannot meet their needs for different viewing angles, making it difficult for them to accurately judge details such as color and proportion, thus reducing work quality.

[0004] In terms of stability, traditional displays also have many shortcomings in design. Typically, displays are placed directly on surfaces like desktops, lacking a stable and reliable support structure. In everyday use, even slight vibrations to the desktop or accidental touches can easily cause the display to wobble. This wobbling not only interferes with normal operation but can also lead to accidental tipping over, causing damage and financial loss to the user. Furthermore, traditional displays struggle to maintain stability after angle adjustments, easily shifting their angle due to external forces, failing to provide a consistently stable visual experience.

[0005] With the continuous advancement of technology, the size and weight of computer monitors are showing diversified development trends. On the one hand, large-size monitors are increasingly favored by the market and are widely used in scenarios such as office meetings and home theaters. However, adjusting the angle of large-size monitors requires greater operational force, and traditional adjustment mechanisms often cannot withstand such force, making the adjustment process laborious and prone to damage. On the other hand, some special-purpose monitors, such as industrial control panels and outdoor displays, may have considerable weight, and traditional support methods are insufficient to ensure their stable placement, posing significant safety risks.

[0006] In conclusion, the development of a computer display device capable of multi-angle adjustment and stable support is urgently needed. This device must overcome the shortcomings of traditional displays in terms of angle adjustment and stability, meet the needs of different users in various usage scenarios, provide users with a more convenient, comfortable, and safe user experience, and promote the upgrading and development of related equipment in the field of information technology engineering.

[0013] The annular rotating block is disposed inside the annular groove.

[0014] Furthermore, the clamping mechanism includes a through hole, a rocker arm, a right-angle plate, a rubber block, a slot, a bottom rod, and a cylindrical spring rod. The top of the positioning frame has a through hole. The rocker arm is rotatably connected to the top of the positioning frame via a rotating shaft. The right-angle plate is rotatably connected to the end of the rocker arm via a rotating shaft. The rubber block is fixedly connected to the bottom of the rocker arm via the bottom rod. The top of the annular rotating block has a slot. The end of the rocker arm is connected to the right-angle plate. The lower end of the right-angle plate contacts the top of the inner wall of the annular groove, which facilitates fixing the rocker arm through the right-angle plate. Four right-angle plates are provided on the surface of the positioning frame. The four right-angle plates are connected to each other by cylindrical spring rods. The right-angle plates are fixedly connected to the cylindrical spring rods.

[0015] The bottom rod is set inside the through hole.

[0016] Furthermore, the rubber block contacts the inner wall of the slot, the bottom of the right-angle plate contacts the top of the inner wall of the annular groove, and the bottom of the rocker arm contacts the top surface of the positioning frame.

[0017] Furthermore, four right-angle plates are provided, and the four right-angle plates are fixedly connected by cylindrical spring rods, which are in contact with the inner ring surface of the positioning frame.

[0018] Furthermore, the auxiliary mechanism includes a top groove, a rubber pad, an arc-shaped spring frame, a rubber floor mat, and rollers. The arc-shaped spring frame is fixedly connected to the bottom of the inner wall of the annular groove. The rollers are fixedly connected to the bottom of the inner wall of the annular groove through the arc-shaped spring frame.

[0019] The bottom of the circular rotating block is provided with a top groove, and the rubber pad is fixedly connected to the top of the inner wall of the top groove.

[0020] Furthermore, the upper end of the roller is disposed inside the top groove, and the upper surface of the roller is in contact with the surface of the rubber pad.

[0021] Furthermore, the stabilizing mechanism includes a spring rod, a sphere, and an arc groove. The spring rod is fixedly connected to the back end of the display screen, the sphere is fixedly connected to the spring rod, and an arc groove is formed inside the arc block.

[0022] The surface of the sphere is in contact with the inner wall of the arc groove.

[0023] The beneficial effects of this invention are as follows:

[0024] When the angle of the display screen needs to be adjusted, the threaded rod is adjusted by twisting the threaded hole rod. When the threaded rod retracts into the threaded hole rod, it pulls the display screen upward through the connecting plate, thereby adjusting the tilt angle of the display screen. When the display screen is tilted, it will slide inside the circular hole block by squeezing the slide rod through the suction cup. The slide rod is squeezed by the display screen and pushes the arc spring to deform. The slide rod squeezes the display screen through the force of the arc spring, which increases the stability of the display screen after the adjustment is completed.

[0025] When the orientation of the display screen needs to be adjusted, the right-angle plate is pulled to separate from the inner wall of the annular groove. After the right-angle plate is separated from the inner wall of the annular groove, the rocker arm will pull the rubber block to separate from the inner wall of the slot through the bottom rod. The display screen is twisted to push the annular rotating block to rotate inside the annular groove. After the orientation of the display screen is adjusted, the rocker arm is pushed to contact the surface of the positioning frame, and the right-angle plate is locked inside the annular groove, so that the rubber block is locked inside the slot to fix the annular rotating block.

[0026] When the circular rotating block of the present invention rotates, it rolls on the surface of the roller through the top groove. The rotation of the roller reduces the friction of the circular rotating block during rotation. When the rubber block squeezes the top of the circular rotating block, the circular rotating block will squeeze the roller to move downward. The roller will contact the surface of the rubber mat as it moves downward. The top of the roller will squeeze the rubber mat to increase the friction, thereby increasing the stability of the circular rotating block.

[0027] The display screen of this invention is fixedly connected to a ball via a spring rod. When the display screen is rotated to adjust its direction, the spring rod will cause the ball to slide inside the arc groove. The display screen is supported by the spring rod, which increases the stability of the display screen after adjustment. Attached Figure Description

The threaded rod 21 is rotatably connected to the surface of the arc-shaped block 12 via a rotating shaft. The threaded rod 24 is threadedly connected to the inner wall of the threaded rod 21. The center of the positioning rod 25 contacts the surface of the threaded rod 24, and the end of the positioning rod 25 is fixedly connected to the round hole block 26. The connecting plate 22 is fixedly connected to the top of the arc-shaped block 12 via the arc-shaped spring piece 20. The slide rod 23 is fixedly connected to the connecting plate 22, and the end of the slide rod 23 away from the connecting plate 22 is fixedly connected to the suction cup 27. The threaded rod 24 is located away from the threaded hole. One end of rod 21 is rotatably connected to connecting plate 28 via bearing. When the angle of display screen 1 needs to be adjusted, the threaded rod 21 is twisted to adjust the threaded rod 24. When the threaded rod 24 retracts into the threaded rod 21, the threaded rod 24 will pull the display screen 1 upward through the connecting plate 28, thereby adjusting the tilt angle of display screen 1. When the display screen 1 is tilted, the suction cup 27 will squeeze the slide rod 23 to slide inside the circular hole block 26. The slide rod 23 is squeezed by the display screen 1, which pushes the arc spring piece 20 to deform. The slide rod 23 squeezes the display screen 1 through the force of the arc spring piece 20, thereby increasing the stability of display screen 1 after adjustment.

[0041] The end of the connecting plate 28 away from the threaded rod 24 is rotatably connected to the back end of the display screen 1 via a rotating shaft. The suction cup 27 contacts the back end of the display screen 1, and the slide rod 23 is slidably connected to the inner wall of the round hole block 26.

[0042] The rotating mechanism 13 includes a positioning frame 30, an annular groove 31, an auxiliary mechanism 32, a fixed ring 33, an annular rotating block 34, a clamping mechanism 35, and a connecting block 36. The positioning frame 30 is fixedly connected to the top of the base 4, the fixed ring 33 is fixedly connected to the surface of the vertical rod 5, and the annular rotating block 34 is fixedly connected to the surface of the fixed ring 33 through the connecting block 36. The positioning frame 30 has an annular groove 31 inside, the auxiliary mechanism 32 is provided at the bottom of the inner wall of the annular groove 31, and the clamping mechanism 35 is provided at the top of the inner wall of the annular groove 31.

[0043] The annular rotating block 34 is disposed inside the annular groove 31.

[0044] The clamping mechanism 35 includes a through hole 40, a rocker arm 41, a right-angle plate 42, a rubber block 43, a slot 44, a base rod 45, and a cylindrical spring rod 46. The positioning frame 30 has a through hole 40 at its top. The rocker arm 41 is rotatably connected to the top of the positioning frame 30 via a pivot. The right-angle plate 42 is rotatably connected to the end of the rocker arm 41 via a pivot. The rubber block 43 is fixedly connected to the bottom of the rocker arm 41 via the base rod 45. The annular rotating block 34 has a slot 44 at its top. The right-angle plate 42 is fixedly connected to the cylindrical spring rod 46. This invention requires adjustment of the rotation of the display screen 1. During adjustment, pull the right-angle plate 42 to separate it from the inner wall of the annular groove 31. After the right-angle plate 42 is separated from the inner wall of the annular groove 31, the rocker arm 41 will pull the rubber block 43 to separate it from the inner wall of the slot 44 through the bottom rod 45. Twist the display screen 1 to push the annular rotating block 34 to rotate inside the annular groove 31. After the direction adjustment of the display screen 1 is completed, push the rocker arm 41 to contact the surface of the positioning frame 30, and then lock the right-angle plate 42 inside the annular groove 31, so that the rubber block 43 is locked inside the slot 44 to fix the annular rotating block 34.

[0045] The bottom rod 45 is located inside the through hole 40.

[0046] The rubber block 43 contacts the inner wall of the slot 44, the bottom of the right-angle plate 42 contacts the top of the inner wall of the annular groove 31, and the bottom of the rocker arm 41 contacts the top surface of the positioning frame 30.

[0047] There are four right-angle plates 42, which are fixedly connected by cylindrical spring rods 46. The cylindrical spring rods 46 are in contact with the inner ring surface of the positioning frame 30.

[0048] The auxiliary mechanism 32 includes a top groove 50, a rubber pad 51, an arc-shaped spring frame 52, a rubber floor mat 53, and a roller 54. The arc-shaped spring frame 52 is fixedly connected to the bottom of the inner wall of the annular groove 31. The roller 54 is rotatably connected to the arc-shaped spring frame 52 via a rotating shaft. The rubber floor mat 53 is fixedly connected to the bottom of the inner wall of the annular groove 31. When the annular rotating block 34 rotates, it rolls on the surface of the roller 54 through the top groove 50. The rotation of the roller 54 reduces the friction of the annular rotating block 34 during rotation. When the rubber block 43 presses the top of the annular rotating block 34, the annular rotating block 34 will press the roller 54 downward. The roller 54 will contact the surface of the rubber floor mat 53 as it moves downward. The top of the roller 54 will press the rubber pad 51 to increase friction, thereby increasing the stability of the annular rotating block 34.

[0049] The bottom of the circular rotating block 34 has a top groove 50, and the rubber pad 51 is fixedly connected to the top of the inner wall of the top groove 50.

The right-angle plate 42 is fixedly connected to the cylindrical spring rod 46.

[0059] The bottom rod 45 is located inside the through hole 40.

[0060] The rubber block 43 contacts the inner wall of the slot 44, the bottom of the right-angle plate 42 contacts the top of the inner wall of the annular groove 31, and the bottom of the rocker arm 41 contacts the top surface of the positioning frame 30.

[0061] There are four right-angle plates 42, which are fixedly connected by cylindrical spring rods 46. The cylindrical spring rods 46 are in contact with the inner ring surface of the positioning frame 30.

[0062] The auxiliary mechanism 32 includes a top groove 50, a rubber pad 51, an arc-shaped spring frame 52, a rubber floor mat 53, and a roller 54.

[0064] The upper end of the roller 54 is located inside the top groove 50, and the upper surface of the roller 54 is in contact with the surface of the rubber pad 51.

[0065] The stabilizing mechanism 11 includes a spring rod 60, a ball 61, and an arc groove 62. The spring rod 60 is fixedly connected to the back end of the display screen 1, and the ball 61 is fixedly connected to the spring rod 60. The arc groove 62 is provided inside the arc block 12. The display screen 1 is fixedly connected to the ball 61 through the spring rod 60. When the display screen 1 is rotated to adjust its direction, the spring rod 60 will drive the ball 61 to slide inside the arc groove 62. The display screen 1 is supported by the spring rod 60, which increases the stability of the display screen 1 after adjustment.

[0066] The surface of sphere 61 is in contact with the inner wall of the arc groove 62.

[0067] A specific application of this embodiment is as follows: When the angle of the display screen 1 needs to be adjusted, the threaded rod 24 is adjusted by twisting the threaded rod 21. When the threaded rod 24 retracts into the threaded rod 21, the threaded rod 24 will pull the display screen 1 upward through the connecting plate 28, thereby adjusting the tilt angle of the display screen 1. When the display screen 1 is tilted, the sliding rod 23 will slide inside the circular hole block 26 by the suction cup 27. The sliding rod 23 is pushed by the display screen 1 to deform the arc spring piece 20. The sliding rod 23 presses the display screen 1 by the force of the arc spring piece 20. When the rotation of the display screen 1 needs to be adjusted, the right angle plate 42 is pulled to separate from the inner wall of the annular groove 31. After the right angle plate 42 is separated from the inner wall of the annular groove 31, the rocker arm 41 will pull the rubber block 43 to separate from the inner wall of the slot 44 through the bottom rod 45. Twisting the display screen 1 pushes the annular rotating block 34 inside the annular groove 31. After the orientation of the display screen 1 is adjusted by rotation, the rocker arm 41 is pushed until it contacts the surface of the positioning frame 30. Then, the right-angle plate 42 is locked inside the annular groove 31, so that the rubber block 43 is locked inside the slot 44 to fix the annular rotating block 34. When the annular rotating block 34 rotates, it will roll on the surface of the roller 54 through the top groove 50. The rotation of the roller 54 reduces the friction of the annular rotating block 34 during rotation. When the rubber block 43 presses the top of the annular rotating block 34, the annular rotating block 34 will press the roller 54 downward. The roller 54 will contact the surface of the rubber mat 53 when it moves downward. The display screen 1 is fixedly connected to the ball 61 by the elastic rod 60. When the orientation of the display screen 1 is adjusted by rotation, the elastic rod 60 will drive the ball 61 to slide inside the arc groove 62. The display screen 1 is supported by the elastic rod 60, which increases the stability of the display screen 1 after adjustment.

[0068] For elastic elements such as "arc spring sheets," "cylindrical spring rods," and "elastic rods," the key parameters are supplemented as follows: The arc spring sheets are made of 65Mn spring steel with a hardness of HRC32-38, an elastic modulus of 205±5GPa, a preload of 6±1N, a thickness of 1.8-2.2mm, a width of 12-15mm, and an arc radius of 28-32mm; the cylindrical spring rods are made of 50CrVA spring steel with a hardness of HRC35-40, an elastic modulus of 210±5GPa, a preload of 4±0.5N, a diameter of 6-8mm, and a length of 45-55mm; the elastic rods are made of 60Si2Mn spring steel with a hardness of HRC38-43, an elastic modulus of 200±5GPa, a preload of 5±0.5N, a diameter of 5-6mm, and a length of 35-45mm. The above parameters ensure that the elastic element has both adjustable feel, structural stability and service life when adapted to displays weighing 3.5-6.0kg.

[0069] After adjustment and locking, a 5N horizontal thrust (simulating daily touch) is applied to the display screen. The maximum shaking amplitude of the display screen is ≤0.4mm, and the shaking duration is ≤0.2s. Compared with traditional support devices that rely on locking screws (shaking amplitude of 2.1-2.5mm and duration of 0.8-1.0s under the same thrust), the stability is improved by more than 80%. The circular rotating block used for steering adjustment has a rotational friction torque of ≤0.7N・m, and 360° continuous steering can be completed with one hand. Compared with the traditional device using the "guide rod + positioning stud" structure (friction torque of 1.6-1.8N・m), the operation is more labor-saving by more than 60%. After 10,000 cycles of adjustment (including pitch and steering adjustment), the elastic decay rate of the arc spring, cylindrical spring rod, and elastic rod is ≤4%, and it can still maintain more than 96% of the initial preload, which is far superior to the traditional spring structure (the elastic decay rate after 10,000 adjustments is usually 18-22%).
