Description

Technical Field

[0001] The present invention relates to the field of computer office technology, and more specifically, to an angle-adjustable curved smart display screen. Background Art

[0002] The angle adjustment function of the curved smart display screen is an important part of improving the user experience. At present, the mainstream curved display screen angle adjustment structures on the market are mainly divided into three categories: mechanical knob type, hydraulic rod type and electric adjustment type. The mechanical knob type structure drives the gear rack mechanism to achieve angle adjustment by manually rotating the knob. Its advantages are simple structure and low cost, but it requires a large operating force during the adjustment process, and it cannot achieve automatic balance of the center of gravity. 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, but there is a risk of oil leakage in the hydraulic system. The damping performance will decrease after long-term use, and the center of gravity balance problem has not been effectively solved. The electric adjustment structure uses a motor to drive the screw nut mechanism for angle adjustment, which can realize automatic control, but the addition of motors and transmission components increases the complexity and cost of the structure, and also faces stability problems caused by the offset of the center of gravity.

[0003] Main defects of existing technology The problem of center of gravity shift is prominent: the existing adjustment structure fails to establish an effective center of gravity feedback mechanism when changing the angle of the display panel. Taking a certain brand of 27-inch curved display as an example, when the display panel is tilted back 15°, the center of gravity shift can reach 18% of the width of the base, causing the front end of the base to be lifted up by 5mm, seriously affecting stability. This center of gravity shift will not only cause the display to shake during use, reducing the user experience, but may also cause fatigue damage to the base support structure due to long-term imbalance of the center of gravity, shortening the service life of the equipment.

[0004] Conflict between adjustment convenience and stability: To improve the convenience of adjustment, some products use sliding parts with low friction coefficients. However, this makes the display screen prone to angle changes due to slight external forces after adjustment, and stability cannot be guaranteed. Products that focus on stability often require additional locking devices, which reduces the convenience of adjustment.

[0005] Complex structure and high maintenance cost: Electric adjustment and hydraulic adjustment structures require complex power systems and transmission components, which are prone to failure due to wear and aging during long-term use, and have high maintenance costs. For example, the sealing ring of the hydraulic rod structure will cause hydraulic oil leakage after aging, and it needs to be replaced by professionals, which increases the user's cost.

[0006] In view of the problems existing in the prior art, such as poor stability caused by the center of gravity offset, difficulty in balancing adjustment convenience and stability, and complex structure and high maintenance cost, the present invention proposes an angle-adjustable curved smart display screen based on a transmission ball balance mechanism. The synchronous control of the display panel angle adjustment and the center of gravity balance is achieved through a mechanical linkage structure, without the need for an additional power source. While ensuring the convenience of adjustment, the center of gravity offset problem is effectively solved, and the stability and reliability of the display screen are improved. Summary of the invention

[0007] In order to overcome the shortcomings of the prior art, the present invention provides an angle-adjustable curved smart display screen, which has the advantage of making the center of gravity of the display panel on the vertical central axis of the base as much as possible after the display panel is adjusted, thereby ensuring the stability of the display panel.

[0008] To achieve the above object, the present invention provides the following technical solution: an angle-adjustable curved smart display screen, comprising: Base; A track groove is provided inside the base along the width direction of the base; A vertical support plate slides along the width direction of the base; Two through plates are respectively fixed to the front and rear sides of the vertical support plate, and the bottom ends thereof penetrate the upper surface of the base and extend to the inside of the track groove; Two supports are respectively fixed to one end of the vertical support plate away from the through plate; Two ball storage tubes are fixed to the front and rear ends of the base respectively, and one end of the two ball storage tubes close to the base is connected to the two ends of the track groove respectively; A communication hole is provided in the upper part of the ball storage tube; The display board is placed directly above the vertical support board; The rotating shaft is fixed at the middle position of one side of the display panel close to the vertical support plate, and its rotating friction is between the two supports; Two pressure rods are respectively fixed to the front and rear sides of the rotating shaft, and the two pressure rods respectively penetrate the connecting holes; A plurality of transmission balls are placed in a 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; The tilting of the display panel drives the pressure rod on the same side as the tilting direction to squeeze the transmission ball, and the transmission ball drives the vertical support plate to move in the direction opposite to the tilting direction of the display panel.

[0009] 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 connecting hole is between 5 cm and 6 cm.

[0010] As a preferred technical solution of the present invention, the contact surface between the rotating shaft and the support is rough, and the friction force between the rotating shaft and the support is twice the gravity of the display panel.

[0011] As a preferred technical solution of the present invention, the width of the connecting hole is smaller than the diameter of the transmission ball, and the connecting hole is opened along the length direction of the ball storage tube.

[0012] As a preferred technical solution of the present invention, the portion of the ball storage tube with the communicating hole is an arc-shaped tube, and the arc-shaped tube is a portion of an annular tube formed with the rotating shaft as the center.

[0013] As a preferred technical solution of the present invention, the inner diameter of the ball storage tube is the same as the inner diameter of the track groove, and the connection between the ball storage tube and the track groove is smooth.

[0014] As a preferred technical solution of the present invention, a T-shaped groove is provided on the upper surface of the base along its width direction, and a T-shaped slider that slidably cooperates with the T-shaped groove in the base is fixed to one end of the vertical support plate close to the base.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention tilts the display panel toward the rear side, and the pressure rod located on the rear side squeezes the transmission ball located on the rear side to move the vertical support plate toward the front side. By tilting the display panel toward the front side, the pressure rod located on the front side squeezes the transmission ball located on the front side to move the vertical support plate toward the rear side, thereby balancing the position of the center of gravity of the display panel and making the center of gravity of the display panel on the vertical central axis of the base as much as possible, thereby ensuring the stability of the display panel and preventing the center of gravity of the display panel from shifting significantly after adjustment, causing the base to tip over.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 10 As shown, the present invention provides an angle-adjustable curved smart display screen, comprising: The base 1 is placed horizontally on the computer desktop; A track groove 11 is provided inside the base 1 along the width direction of the base 1; A vertical support plate 2 slides along the width direction of the base 1, and a T-shaped slide groove is provided on the upper surface of the base 1 along its width direction. A T-shaped slider that slides with the T-shaped slide groove in the base 1 is fixed to one end of the vertical support plate 2 close to the base 1; Two through plates 21 are fixed to the front and rear sides of the vertical support plate 2, respectively, and the bottom ends thereof penetrate the upper surface of the base 1 and extend to the inside of the track groove 11; Two supports 22 are respectively fixed to one end of the vertical support plate 2 away from the through plate 21; Two ball storage tubes 3 are fixed to the front and rear ends of the base 1, and one end of the two ball storage tubes 3 close to the base 1 is connected to the two ends of the track groove 11, respectively. The inner diameter of the ball storage tube 3 is the same as the inner diameter of the track groove 11, and the connection between the ball storage tube 3 and the track groove 11 is smooth. A communication hole 31 is provided in the upper part of the ball storage tube 3; The display panel 4 is placed directly above the vertical support panel 2; The rotating shaft 41 is fixed to the middle position of one side of the display board 4 close to the vertical support plate 2, and its rotation friction is between the two supports 22. The contact surface between the rotating shaft 41 and the support 22 is rough, and the friction between the rotating shaft 41 and the support 22 is twice the weight of the display board 4. The part of the ball storage tube 3 with the connecting hole 31 is an arc tube, and the arc tube is a part of an annular tube formed with the rotating shaft 41 as the center. Two pressing rods 42 are fixed to the front and rear sides of the rotating shaft 41 respectively. The two pressing rods 42 penetrate the connecting holes 31 respectively. When the display panel 4 is in a vertical state, the length of the pressing rods 42 extending through the connecting holes 31 is between 5 cm and 6 cm. 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 located between the pressure 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 opened along the length direction of the ball storage tube 3. The display panel 4 tilts to drive the pressure rod 42 on the same side as the tilt direction to squeeze the transmission ball 5 , and the transmission ball 5 drives the vertical support plate 2 to move in the direction opposite to the tilt direction of the display panel 4 .

[0020] The angle-adjustable curved smart display provided by the present invention is mainly composed of four parts: a base, a vertical support component, an angle adjustment component, and a display panel component. The components are linked by precise mechanical linkage design to achieve automatic balance of the center of gravity during the angle adjustment process.

[0021] Base The base 1 is the supporting 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 and is formed by die-casting. It has the characteristics of light weight and high strength. A track groove 11 is opened inside the base 1 along the width direction. The cross-sectional shape of the track groove 11 is rectangular, with a width of 30mm and a depth of 25mm, providing a guide space for the sliding of the vertical support assembly. A T-shaped slide groove is opened on the upper surface of the base 1 along the width direction. The opening width of the slide groove is 15mm, the bottom width of the groove is 20mm, and the depth is 10mm. It forms a sliding fit with the T-shaped slider of the vertical support assembly. This T-shaped structural design can effectively prevent the vertical support assembly from detaching from the base 1 during the sliding process, thereby improving the reliability of the structure.

[0022] Vertical support assembly 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 and has good rigidity and corrosion resistance. The two through plates 21 are respectively fixed to the front and rear sides of the vertical support plate 2 and connected to the vertical support plate 2 by welding to ensure the connection strength. The bottom end of the through plate 21 passes through the upper surface of the base 1 and extends to the inside of the track groove 11. Its extension length in the track groove 11 is 20 mm, which is used to contact and transmit force with the transmission ball 5. A T-shaped slider is fixed to the end of the vertical support plate 2 close to the base 1. The size of the slider matches the T-shaped slide groove on the base 1. The height of the slider is 12 mm, ensuring good guidance and stability during the sliding process.

[0023] Angle adjustment kit The angle adjustment assembly is the core part of the present invention, and includes a ball storage tube 3 , a connecting hole 31 , a rotating shaft 41 , a pressure rod 42 and a transmission ball 5 .

[0024] Ball storage tube 3: Two ball storage tubes 3 are fixed to the front and rear ends of the base 1 respectively, and are made of engineering plastic injection molding, which has good wear resistance and corrosion resistance. The end of the ball storage tube 3 close to the base 1 is connected with the two ends of the track groove 11. The connection part adopts an arc transition design with a transition radius of 5mm to ensure that the transmission ball 5 can move smoothly when passing through the connection. The part of the ball storage tube 3 with the connecting hole 31 is an arc tube. 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 80mm. A part of the annular tube is formed with the rotating shaft 41 as the center of the circle. This design enables the pressure 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 efficiency of force transmission.

[0025] The connecting hole 31 is opened in the upper part of the ball storage tube 3 and along the length direction of the ball storage tube 3. The length is 50 mm and the width is 8 mm, which is smaller than the diameter (10 mm) of the transmission ball 5. Such a design can ensure that the pressure rod 42 passes through the connecting hole 31 and contacts the transmission ball 5, and can prevent the transmission ball 5 from falling off from the connecting hole 31.

[0026] Rotating shaft 41: fixed at the middle position of one side of the display panel 4 close to the vertical support plate 2, made of 45# steel after quenching and tempering, with a surface roughness Ra of 1.6μm. The contact surface between the rotating shaft 41 and the support 22 is knurled to increase the roughness of the contact surface, and the friction between the rotating shaft 41 and the support 22 is designed to be twice the weight of the display panel 4. Assuming that the weight of the display panel 4 is G, the friction force F=2G can be calculated by the formula. Such a friction setting can not only ensure that the display panel 4 can maintain a stable angle after adjustment, but also facilitate the user to adjust the angle by manually applying appropriate force.

[0027] Pressure rod 42: fixed to the front and rear sides of the rotating shaft 41, made of aluminum alloy, with a rectangular cross-section, a width of 10 mm, and a thickness of 5 mm. When the display panel 4 is in a vertical state, the length of the pressure rod 42 extending through the connecting 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 panel 4 is tilted to the maximum angle (±30°), the pressure rod 42 can still effectively squeeze the transmission ball 5, while avoiding interference between the pressure rod 42 and the ball storage tube 3 in the vertical state.

[0028] Transmission ball 5: placed in the through track formed by the ball storage tube 3 and the track groove 11, a stainless steel ball with a diameter of 10 mm is used, the surface is polished, and the surface roughness Ra is 0.8 μm to reduce the friction resistance during the transmission process. Multiple transmission balls 5 are arranged linearly in the through track, located between the pressure rod 42 and the through plate 21 on the same side, forming a force transmission chain.

[0029] Display panel components The display panel 4 is connected to the vertical support assembly via a rotating shaft 41 . The distance from the center of the rotating shaft 41 to the center of the display panel 4 screen is 100 mm, ensuring that the change in the center of gravity of the display panel 4 during rotation can be effectively transmitted to the transmission ball 5 via the pressure rod 42 .

[0030] Since the display panel 4 is tilted toward the rear, the center of gravity of the display panel 4 will move rearward with the change of the tilt angle. The tilting of the display panel 4 toward the rear can drive the rotating shaft 41 to rotate, so that the pressure rod 42 located at the rear side squeezes the transmission ball 5 at the top end at the rear side. Through the transmission of the remaining transmission balls 5, the through plate 21 located at the rear side of the vertical support plate 2 can be squeezed, so that the vertical support plate 2 moves forward. The tilting of the display panel 4 toward the rear will cause the vertical support plate 2 and the display panel 4 above the vertical support plate 2 to move forward, so that the center of gravity of the display panel 4 can be moved forward, and the center of gravity of the display panel 4 can be placed on the vertical central axis of the base 1 as much as possible. Conversely, when the display panel 4 is tilted forward, the vertical support plate 2 will move rearward, thereby ensuring the stability of the display panel 4 and preventing the center of gravity of the display panel 4 from shifting significantly after adjustment, causing the base 1 to tip over.

[0031] The present invention tilts the display panel 4 toward the rear side, and the pressure rod 42 located on the rear side squeezes the transmission ball 5 located on the rear side to move the vertical support plate 2 toward the front side. By tilting the display panel 4 toward the front side, the pressure rod 42 located on the front side squeezes the transmission ball 5 located on the front side to move the vertical support plate 2 toward the rear side, thereby balancing the position of the center of gravity of the display panel 4 and making the center of gravity of the display panel 4 on the vertical central axis of the base 1 as much as possible, thereby ensuring the stability of the display panel 4 and preventing the center of gravity of the display panel 4 from shifting significantly after adjustment, causing the base 1 to tip over.

[0032] Assembly Process Installation of the base: First, the track groove 11 is formed inside the base 1 by milling, and then a T-shaped slide groove is processed 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, and the connection between the ball storage tube 3 and the track groove 11 is ensured to be smooth. Use a feeler gauge to check the gap at the connection, which is required to be no greater than 0.1mm.

[0033] Installation of vertical support assembly: Fix the T-shaped slider to the bottom of the vertical support plate 2 by welding, and then insert the vertical support plate 2 into the T-shaped slide groove of the base 1, ensuring that the vertical support plate 2 can slide freely in the width direction of the base 1. Fix the two through plates 21 to the front and rear sides of the vertical support plate 2 by bolts respectively, and adjust the position of the through plates 21 so that the extension length of the bottom end in the track groove 11 is 20 mm.

[0034] Angle adjustment assembly installation: Fix the rotating shaft 41 to the center of the back of the display board 4 with bolts, and then place the display board 4 just above the vertical support plate 2, so that the two ends of the rotating shaft 41 are respectively inserted into the bearing holes of the support 22. Fix the two pressure rods 42 to the front and rear sides of the rotating shaft 41 with screws, respectively, to ensure that the pressure rods 42 can accurately penetrate the connecting hole 31 on the ball storage tube 3. Put 7 transmission balls 5 in turn in the through track formed by the ball storage tube 3 and the track groove 11, to ensure that the transmission balls 5 can roll smoothly in the track.

[0035] Overall debugging: Manually push the display board 4 to adjust the angle, check whether the vertical support plate 2 slides smoothly and whether the transmission ball 5 is flexible. Use a level to detect the center of gravity balance of the display board 4 at different angles, adjust the extension length of the pressure rod 42 and the friction 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.

[0036] Material selection and manufacturing process Base 1: It is made of 6061 aluminum alloy die-casting, the die-casting temperature is controlled at 680℃-720℃, and the mold preheating temperature is 200℃-250℃. The high-pressure die-casting process ensures that the base 1 has good dimensional accuracy and surface quality. After molding, T6 heat treatment is performed to improve the strength and hardness of the aluminum alloy.

[0037] Vertical support plate 2 and through plate 21: 304 stainless steel plate is bent and formed, with a bending angle of 90° and a bending radius of 3mm. After bending, welding is performed using argon arc welding technology, with a welding current of 80A-100A and a welding speed of 100mm / min-150mm / min, to ensure that the welded joint has good strength and sealing.

[0038] Ball storage tube 3: Polyoxymethylene (POM) engineering plastics are used for injection molding, the injection molding temperature is controlled at 200℃-220℃, and the mold temperature is 80℃-90℃. After injection molding, deburring is performed to ensure that the inner surface of the ball storage tube 3 is smooth and the transmission ball 5 can move smoothly.

[0039] Rotating shaft 41 and pressure rod 42: The rotating shaft 41 is made of 45# steel by turning, and the surface is knurled with a knurling depth of 0.3mm-0.5mm to increase the friction with the support 22. The pressure rod 42 is extruded from aluminum alloy with an extrusion speed of 5mm / s-8mm / s and an extrusion temperature of 450℃-500℃. After forming, it is anodized to improve the surface hardness and wear resistance.

[0040] Transmission ball 5: GCr15 bearing steel is formed by cold heading process, and then quenched and tempered. The quenching temperature is 840℃-860℃, and the tempering temperature is 150℃-170℃, ensuring that the transmission ball 5 has high hardness and wear resistance, and the surface hardness reaches HRC60-62.

[0041] The application scenarios are as follows: Office scene: In a regular office environment, users can adjust the angle of the display panel 4 at any time according to their sitting posture and light conditions to ensure the best viewing angle. When users need to read documents for a long time, they can tilt the display panel 4 back 10°-15°. The display panel 4 is a curved smart display screen, using a 27-inch curved LCD panel with a curvature radius of 1800R, which can provide a wide viewing angle of 178° and a display resolution of 2560×1440, reducing neck fatigue; when entering data, the display panel 4 can be adjusted to a vertical state for quick operation of the keyboard and mouse.

[0042] Graphic design scenario: In graphic design work, designers need to frequently observe the details and overall effect of graphics. By adjusting the angle of the display panel 4, the graphics can be presented from different perspectives, helping designers to design and modify more accurately. For example, tilting the display panel 4 forward by 20°-25° can make the graphics more three-dimensional visually, making it easier to observe the three-dimensional effect of the graphics.

[0043] Video conference scene: During a video conference, in order to allow participants to clearly see the content on the display panel 4, the display panel 4 can be tilted back 5°-10° to avoid the influence of light reflection on the picture. At the same time, the center of gravity balance mechanism of the present invention ensures that the display screen is stable and reliable during the conference and will not shake due to slight collisions.

[0044] Education and training scenarios: In classrooms or training rooms, the curved smart display can be used as a teaching display tool. Teachers can adjust the angle of the display board 4 according to different teaching content and student seating distribution so that all students can get a good viewing effect. For example, when explaining PPT, adjust the display board 4 to a vertical state; when playing experimental demonstration videos, tilt the display board 4 backward by 15°-20° to expand the students' viewing angle.
