Description

Technical Field

[0001] The present invention belongs to the field of display technology, and particularly relates to an angle-adjustable curved intelligent display screen, and more particularly to an angle adjustment structure of the display screen. Background Art

[0002] The angle adjustment function of the curved intelligent display screen is an important part of enhancing the user experience. Currently, the mainstream angle adjustment structures of curved display screens on the market are mainly divided into three categories: mechanical knob type, hydraulic rod type, and electric adjustment type. The mechanical knob type structure realizes angle adjustment by manually rotating the knob to drive the gear-rack mechanism. Its advantages are simple structure and low cost, but a large operating force is required during the adjustment process, and the automatic balance of the center of gravity cannot be achieved. After adjustment, the display screen is prone to shaking due to the offset of the center of gravity. The hydraulic rod type structure uses the damping effect of hydraulic oil to achieve smooth adjustment, and has the advantage of a smooth adjustment process. However, there is a risk of oil leakage in the hydraulic system, and the damping performance will decline after long-term use, and the problem of center of gravity balance has not been effectively solved. The electric adjustment type structure adjusts the angle by driving the screw-nut mechanism with a motor, and can achieve automatic control. However, the addition of the motor and transmission components increases the structural complexity and cost, and at the same time also faces the stability problem caused by the offset of the center of gravity.

[0003] Main Defects of the Existing Technology

[0004] The problem of center of gravity offset is prominent: When the existing adjustment structure changes the angle of the display board, an effective center of gravity feedback mechanism is not established. Taking a 27-inch curved display screen of a certain brand as an example, when the display board tilts backward by 15°, the center of gravity offset can reach 18% of the base width, resulting in a lifting height of 5 mm at the front end of the base, seriously affecting the stability. This center of gravity offset will not only cause the display screen to shake during use, reducing the user experience, but may also cause fatigue damage to the base support structure due to long-term center of gravity imbalance, shortening the service life of the device.

[0005] The contradiction between adjustment convenience and stability: To improve the adjustment convenience, some products use sliding components with a low friction coefficient, but this makes the display screen prone to angle changes due to slight external forces after adjustment, and the stability cannot be guaranteed; while products that focus on stability often need to add additional locking devices, which will reduce the adjustment convenience.

[0006] Complex structure and high maintenance cost: Electric adjustment and hydraulic adjustment structures need to be equipped with complex power systems and transmission components. These components are prone to failures due to wear, aging, etc. during long-term use, and the maintenance cost is relatively high. For example, when the sealing ring of the hydraulic rod type structure ages, it will cause hydraulic oil leakage, and professional personnel are required for replacement, increasing the user's usage cost.

[0007] In view of the problems existing in the prior art, such as poor stability caused by the center-of-gravity shift, difficulty in balancing the adjustment convenience and stability, and high maintenance cost due to the complex structure, the present invention proposes an angle-adjustable curved intelligent display screen based on a transmission ball balance mechanism. Through a mechanical linkage structure, synchronous control of the angle adjustment and center-of-gravity balance of the display board is achieved, without the need for an additional power source. While ensuring the adjustment convenience, the problem of center-of-gravity shift is effectively solved, and the stability and reliability of the display screen are improved. Summary of the Invention

[0008] In order to overcome the deficiencies of the prior art, the present invention provides an angle-adjustable curved intelligent display screen, which has the advantage of ensuring the stability of the display board by making the center of gravity of the display board as close as possible to the vertical central axis of the base after the display board is adjusted.

[0020] A plurality of transmission balls, which are placed in the through track formed by the ball storage tube and the track groove, and are located between the pressure rod and the through plate on the same side;

[0021] Among them: When the display board tilts, the pressure rod on the same side as the tilting direction squeezes the transmission ball, and through the transmission of the transmission ball, the vertical support plate moves in the direction opposite to the tilting direction of the display board.

[0022] As a preferred technical solution of the present invention, when the display panel is in a vertical state, the length of the pressure rod extending through the communication hole is between 5 cm and 6 cm.

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] As Figures 1 to 10 shown, the present invention provides an angle-adjustable curved intelligent display screen, including:

[0048] Base 1, horizontally placed on the computer desktop;

[0049] Track groove 11, opened inside the base 1 along the width direction of the base 1;

[0050] The vertical support plate 2 slides along the width direction of the base 1. A T-shaped chute is provided on the upper surface of the base 1 along its width direction. A T-shaped slider that is slidably engaged with the T-shaped chute inside the base 1 is fixed to one end of the vertical support plate 2 close to the base 1.

[0051] Two through plates 21 are respectively fixed to the front and rear sides of the vertical support plate 2. The bottom ends thereof penetrate through the upper surface of the base 1 and extend into the inside of the track groove 11.

[0052] Two supports 22 are respectively fixed to one end of the vertical support plate 2 far from the through plate 21.

[0053] Two ball storage tubes 3 are respectively fixed to the front and rear ends of the base 1. One ends of the two ball storage tubes 3 close to the base 1 are respectively communicated with the two ends of the track groove 11. The inner diameter of the ball storage tube 3 is the same as the inner diameter of the track groove 11. The connection between the ball storage tube 3 and the track groove 11 is smooth.

[0054] A communication hole 31 is provided in the upper half of the ball storage tube 3.

[0055] A display board 4 is placed directly above the vertical support plate 2.

[0056] A rotating shaft 41 is fixed to the middle position on the side of the display board 4 close to the vertical support plate 2. Its rotational friction is between the two supports 22. The contact surface between the rotating shaft 41 and the supports 22 is rough. The frictional force between the rotating shaft 41 and the supports 22 is twice the gravity of the display board 4. The part of the ball storage tube 3 provided with the communication hole 31 is an arc-shaped tube, and the arc-shaped tube is a part of an annular tube formed with the rotating shaft 41 as the center.

[0057] Two pressing rods 42 are respectively fixed to the front and rear sides of the rotating shaft 41. The two pressing rods 42 respectively penetrate through the communication hole 31. When the display board 4 is in the vertical state, the length of the pressing rod 42 extending out through the communication hole 31 is between 5 cm and 6 cm.

[0058] A plurality of transmission balls 5 are placed in the through track formed by the ball storage tube 3 and the track groove 11, and are between the pressing rod 42 and the through plate 21 on the same side. The width of the communication hole 31 is smaller than the diameter of the transmission ball 5, and the communication hole 31 is provided along the length direction of the ball storage tube 3.

[0059] Wherein: When the display board 4 is tilted, the pressing rod 42 on the same side as the tilting direction squeezes the transmission ball 5. Through the transmission of the transmission ball 5, the vertical support plate 2 moves in the direction opposite to the tilting direction of the display board 4.

[0060] Since the display board 4 is tilted backward, the center of gravity of the display board 4 will move backward as the tilt angle changes. Tilting the display board 4 backward can drive the rotation shaft 41 to rotate, so that the pressing rod 42 at the rear can squeeze the transmission ball 5 at the topmost position at the rear. Through the transmission of the remaining transmission balls 5, the through plate 21 at the rear on the vertical support plate 2 can be squeezed, so that the vertical support plate 2 moves forward. Tilting the display board 4 backward will cause the vertical support plate 2 and the display board 4 above the vertical support plate 2 to move forward. Therefore, the center of gravity of the display board 4 can be moved forward, and the center of gravity of the display board 4 can be made to be on the vertical central axis of the base 1 as much as possible. On the contrary, tilting the display board 4 forward, the vertical support plate 2 will move backward, thus ensuring the stability of the display board 4 and preventing the center of gravity of the display board 4 from shifting greatly after adjustment, resulting in the base 1 tipping over.

[0061] In the present invention, by tilting the display board 4 backward, the pressing rod 42 at the rear will squeeze the transmission ball 5 at the rear to make the vertical support plate 2 move forward. By tilting the display board 4 forward, the pressing rod 42 at the front will squeeze the transmission ball 5 at the front to make the vertical support plate 2 move backward, thereby balancing the position of the center of gravity of the display board 4, making the center of gravity of the display board 4 on the vertical central axis of the base 1 as much as possible, thus ensuring the stability of the display board 4 and preventing the center of gravity of the display board 4 from shifting greatly after adjustment, resulting in the base 1 tipping over.

[0062] Overall structural design

[0063] The angle-adjustable curved intelligent display screen provided by the present invention mainly consists of four major parts: a base, a vertical support assembly, an angle adjustment assembly, and a display board assembly. Through precise mechanical linkage design among the components, automatic balance of the center of gravity during the angle adjustment process is achieved.

[0064] Base

[0065] The base 1 serves as the support foundation of the entire display screen, and its design directly affects the stability of the display screen. The base 1 is made of high-strength aluminum alloy material and is formed by die-casting process, featuring light weight and high strength. A track groove 11 is provided inside the base 1 along the width direction. The cross-sectional shape of the track groove 11 is rectangular, with a width of 30 mm and a depth of 25 mm, providing a guiding space for the sliding of the vertical support assembly. A T-shaped sliding groove is provided on the upper surface of the base 1 along the width direction. The opening width of the sliding groove is 15 mm, the bottom width of the groove is 20 mm, and the depth is 10 mm, forming a sliding fit with the T-shaped slider of the vertical support assembly. This T-shaped structure design can effectively prevent the vertical support assembly from disengaging from the base 1 during the sliding process and improve the reliability of the structure.

[0066] Vertical support assembly

[0067] The vertical support assembly includes a vertical support plate 2 and two through plates 21. The vertical support plate 2 is formed by bending a stainless steel plate with a thickness of 5 mm, having good rigidity and corrosion resistance. The two through plates 21 are respectively fixed on the front and rear sides of the vertical support plate 2, and are connected to the vertical support plate 2 by welding process to ensure the connection strength. The bottom end of the through plate 21 penetrates the upper surface of the base 1 and extends into the inside of the track groove 11, and its extension length in the track groove 11 is 20 mm, which is used to contact the transmission ball 5 and transmit force. One end of the vertical support plate 2 close to the base 1 is fixed with a T-shaped slider, and the size of the slider matches the T-shaped chute on the base 1. The height of the slider is 12 mm, ensuring good guiding and stability during the sliding process.

[0068] Angle adjustment assembly

[0069] The angle adjustment assembly is the core part of the present invention, including a ball storage tube 3, a communication hole 31, a rotating shaft 41, a pressing rod 42 and a transmission ball 5.

[0070] Ball storage tube 3: Two ball storage tubes 3 are respectively fixed at the front and rear ends of the base 1, and are injection molded with engineering plastics, having good wear resistance and corrosion resistance. One end of the ball storage tube 3 close to the base 1 is communicated with both ends of the track groove 11, and the communication part is designed with an arc transition, and the transition radius is 5 mm, ensuring that the transmission ball 5 can move smoothly when passing through the connection part. The part of the ball storage tube 3 provided with the communication hole 31 is an arc tube, and the curvature radius of the arc tube is equal to the distance from the center of the rotating shaft 41 to the center of the ball storage tube 3, both of which are 80 mm, forming a part of an annular tube with the rotating shaft 41 as the center. This design enables the pressing rod 42 to always be perpendicular to the arc surface of the ball storage tube 3 when rotating with the display board 4, ensuring the force transmission efficiency.

[0071] Communication hole 31: It is opened in the upper half of the ball storage tube 3, opened along the length direction of the ball storage tube 3, with a length of 50 mm and a width of 8 mm, which is smaller than the diameter (10 mm) of the transmission ball 5. Such a design can not only ensure that the pressing rod 42 penetrates the communication hole 31 and contacts the transmission ball 5, but also prevent the transmission ball 5 from falling off from the communication hole 31.

[0072] Rotating shaft 41: Fixed at the middle position on the side of the display board 4 close to the vertical support plate 2, made of 45# steel after quenching and tempering treatment, with a surface roughness Ra of 1.6 μm. The contact surface between the rotating shaft 41 and the support 22 is knurled to increase the roughness of the contact surface. The frictional force between the rotating shaft 41 and the support 22 is designed to be 2 times the gravity of the display board 4. Assuming the gravity of the display board 4 is G, the frictional force F = 2G can be obtained through formula calculation. Such a frictional force setting can not only ensure that the display board 4 can stably maintain the angle after adjustment, but also facilitate the user to adjust the angle by manually applying an appropriate force.

[0073] Pressing rod 42: Fixed on the front and rear sides of the rotating shaft 41 respectively, made of aluminum alloy material, with a rectangular cross-section shape, a width of 10 mm, and a thickness of 5 mm. When the display board 4 is in the vertical state, the length of the pressing rod 42 extending through the communication hole 31 is between 5 cm and 6 cm. After a large number of experimental verifications, this length range can ensure that when the display board 4 is tilted to the maximum angle (±30°), the pressing rod 42 can still effectively press the transmission ball 5, while avoiding interference between the pressing rod 42 and the ball storage tube 3 in the vertical state.

[0074] Transmission ball 5: Placed in the through-track formed by the ball storage tube 3 and the track groove 11, made of a stainless steel ball with a diameter of 10 mm, the surface is polished, and the surface roughness Ra is 0.8 μm to reduce the frictional resistance during the transmission process. Multiple transmission balls 5 are linearly arranged in the through-track, between the pressing rod 42 and the through plate 21 on the same side, forming a force transmission chain.

[0075] Display board assembly

[0076] The display board 4 is a curved intelligent display screen, using a 27-inch curved liquid crystal panel with a curvature radius of 1800R, which can provide a wide viewing angle of 178°, and the display resolution is 2560×1440. The display board 4 is connected to the vertical support assembly through the rotating shaft 41. The distance from the center of the rotating shaft 41 to the center of the screen of the display board 4 is 100 mm, ensuring that the change in the center of gravity of the display board 4 during rotation can be effectively transmitted to the transmission ball 5 through the pressing rod 42.

[0077] Assembly process

[0078] Base Installation: First, the track groove 11 is formed inside the base 1 through milling, and then a T-shaped sliding groove is machined on the upper surface of the base 1. The ball storage tube 3 is fixed to the front and rear ends of the base 1 by screws, ensuring that the connection between the ball storage tube 3 and the track groove 11 is smooth. Use a feeler gauge to check the gap at the connection, and the requirement is that the gap is not greater than 0.1 mm.

[0079] Vertical Support Component Installation: The T-shaped slider is fixed to the bottom end of the vertical support plate 2 by welding, and then the vertical support plate 2 is inserted into the T-shaped sliding groove of the base 1, ensuring that the vertical support plate 2 can slide freely in the width direction of the base 1. The two through plates 21 are respectively fixed to the front and rear sides of the vertical support plate 2 by bolts, and the position of the through plate 21 is adjusted so that the extension length of its bottom end in the track groove 11 is 20 mm.

[0080] Angle Adjustment Component Installation: The rotating shaft 41 is fixed to the center position of the back surface of the display board 4 by bolts, and then the display board 4 is placed directly above the vertical support plate 2, so that both ends of the rotating shaft 41 are respectively inserted into the bearing holes of the support 22. The two pressure rods 42 are respectively fixed to the front and rear sides of the rotating shaft 41 by screws, ensuring that the pressure rods 42 can accurately penetrate the communication holes 31 on the ball storage tube 3. Seven transmission balls 5 are sequentially placed in the through track formed by the ball storage tube 3 and the track groove 11, ensuring that the transmission balls 5 can roll smoothly in the track.

[0081] Overall Debugging: Manually push the display board 4 for angle adjustment, check whether the sliding of the vertical support plate 2 is smooth and whether the transmission of the transmission balls 5 is flexible. Use a level to detect the center of gravity balance of the display board 4 at different angles, and adjust the extension length of the pressure rod 42 and the friction force of the rotating shaft 41 until the display board 4 can remain stable at any angle and the center of gravity offset does not exceed 5% of the base width.

[0082] Material Selection and Manufacturing Process

[0083] Base 1: It is formed by die-casting 6061 aluminum alloy. The die-casting temperature is controlled at 680°C - 720°C, and the mold preheating temperature is 200°C - 250°C. Through the high-pressure die-casting process, it is ensured that the base 1 has good dimensional accuracy and surface quality. After forming, T6 heat treatment is carried out to improve the strength and hardness of the aluminum alloy.

[0084] Vertical support plate 2 and through plate 21: They are formed by bending a 304 stainless steel plate, with a bending angle of 90° and a bending radius of 3 mm. After bending, welding treatment is carried out. Tungsten inert gas (TIG) welding process is used for welding, with a welding current of 80 A - 100 A and a welding speed of 100 mm / min - 150 mm / min, ensuring that the welded joint has good strength and sealing performance.

[0085] Ball storage tube 3: It is injection molded using polyoxymethylene (POM) engineering plastic. The injection molding temperature is controlled at 200°C - 220°C, and the mold temperature is 80°C - 90°C. After injection molding, deburring treatment is carried out to ensure that the inner surface of the ball storage tube 3 is smooth and the transmission ball 5 can move smoothly.

[0086] Rotating shaft 41 and pressure rod 42: The rotating shaft 41 is made of 45 steel through turning processing, and its surface is knurled with a knurling depth of 0.3 mm - 0.5 mm to increase the friction with the support 22. The pressure rod 42 is formed by aluminum alloy extrusion with an extrusion speed of 5 mm / s - 8 mm / s and an extrusion temperature of 450°C - 500°C. After forming, anodic oxidation treatment is carried out to improve the surface hardness and wear resistance.

[0087] Transmission ball 5: It is formed by cold heading using GCr15 bearing steel. After forming, quenching and tempering treatments are carried out. The quenching temperature is 840°C - 860°C, and the tempering temperature is 150°C - 170°C, ensuring that the transmission ball 5 has high hardness and wear resistance, and the surface hardness reaches HRC60 - 62.

[0088] Expansion of application scenarios

[0089] Office scenario: In a conventional office environment, users can adjust the angle of the display board 4 at any time according to their sitting postures and lighting conditions to ensure the best viewing angle. When users need to read documents for a long time, the display board 4 can be tilted backward by 10° - 15° to reduce neck fatigue; when performing data input, the display board 4 can be adjusted to a vertical state for easy operation of the keyboard and mouse.

[0090] Graphic design scenario: In graphic design work, designers need to frequently observe the details and overall effects of graphics. By adjusting the angle of the display board 4, the graphics can be presented from different perspectives, helping designers design and modify more accurately. For example, when the display board 4 is tilted forward by 20° - 25°, the graphics will be more three-dimensional visually, facilitating the observation of the three-dimensional effect of the graphics.

[0091] Video conferencing scenario: During a video conference, to enable participants to clearly see the content on display board 4, the display board 4 can be tilted backward by 5° - 10° to avoid the impact of light reflection on the screen. At the same time, through the center of gravity balance mechanism of the present invention, it is ensured that the display screen is stable and reliable during the meeting and will not shake due to slight collisions.

[0092] Education and training scenario: In a classroom or training room, the curved intelligent display screen can be used as a teaching display tool. Teachers can adjust the angle of display board 4 according to different teaching contents and the seating distribution of students, so that all students can obtain a good viewing effect. For example, when explaining a PPT, the display board 4 is adjusted to the vertical state; when playing an experimental demonstration video, the display board 4 is tilted backward by 15° - 20° to expand the viewing angle of students.
