Description

Technical Field

[0001] This utility model relates to the field of display accessories technology, specifically to a display angle adjustment damping hinge structure. Background Technology

[0002] A monitor (also known as a display screen or screen) is an output device that converts electronic signals into visible images. It is mainly used to display text, graphics, or video content generated by electronic devices. The monitor is the "visual terminal" of electronic devices. It receives electronic signals through specific transmission equipment and converts digital signals into dynamic images that can be recognized by humans. Essentially, it is a light and shadow medium for information output. In order to adapt to the viewing habits and usage environment of different users, the angle adjustment function of the monitor has become an essential feature. The core component to realize this function is the damping hinge structure.

[0003] Existing damping hinge structures adjust the display angle by rotating the hinge, and automatically lock the angle with the damping structures at both ends of the hinge, thus achieving the effect of rapid adjustment of the display angle. However, the damping structures at both ends of the hinge achieve the damping effect by stacking friction plates or using special damping sleeves. Because the friction surface that provides damping force is small, it cannot provide a large damping force, which cannot meet the long-term use of some medium and large displays. In addition, the damping performance decays quickly. Therefore, we need to propose a display angle adjustment damping hinge structure. Summary of the Invention

[0004] The purpose of this utility model is to provide a damping shaft structure for adjusting the angle of a display. Through the damping mechanism inside the rotating frame, several sets of sliding rods are symmetrically and evenly distributed on both sides of the rotating frame. The sliding rods slide in cooperation with the side wall of the rotating frame, and one end of the sliding rod slides through the interior of the rotating frame and is fixedly connected to the clamping plate. Two sets of clamping plates are symmetrically arranged on both sides of the fixed rod. Springs are movably fitted on the outer arc surface of several sets of sliding rods. When the springs are in their natural state, they can push the two sets of clamping plates to fit tightly against the surface of the fixed rod through elastic force, generating a stable frictional force and forming a damping effect on the rotating frame. Because the contact area between the two sets of clamping plates and the fixed rod is large, the stability of the damping is improved, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a display angle adjustment damping pivot structure, comprising a rotating assembly, the rotating assembly including a base, two sets of support plates fixedly installed on the top of the base, a fixing rod threaded through the inner sidewalls of the two sets of support plates, a rotating frame for adjusting the display screen angle rotatably mounted on the outer arc surface of the middle of the fixing rod, a damping mechanism installed inside the rotating frame, and a mounting assembly for connecting the display screen installed on the top of the rotating frame; the damping mechanism includes several sets of sliding rods, the several sets of sliding rods being symmetrically and evenly distributed on both sides of the rotating frame, and one end of each set of sliding rods slidingly penetrating into the interior of the rotating frame and mounted with two sets of clamping plates, the other end of each set of sliding rods being fixedly mounted with a limiting plate, the two sets of clamping plates being symmetrically arranged on both sides of the fixing rod, and a set of springs providing clamping force to the clamping plates being movably mounted on the outer arc surface of each set of sliding rods.

[0006] Preferably, the two sets of clamping plates are arranged in an arc shape, and the clamping surfaces of the two sets of clamping plates are adapted to fit the outer arc surface of the fixing rod.

[0007] Preferably, the damping mechanism further includes two sets of adjusting plates, both sets of adjusting plates being located between a set of clamping plates and the inner sidewall of the rotating frame, and the two sets of adjusting plates being slidably fitted onto the outer arc surface of the sliding rods on both sides.

[0010] Preferably, a square groove is provided through the middle of both sets of support plates, and the outer arc surfaces at both ends of the fixing rod are set into rectangles that match the directional groove.

[0011] Preferably, the mounting assembly includes a fixing frame that is fixedly bolted to the top of the rotating frame, and the top of the fixing frame has a plurality of mounting holes and slots.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4This utility model provides a damping shaft structure for adjusting the angle of a display screen, including a rotating assembly 1. The rotating assembly 1 includes a base 11, and two sets of support plates 12 are fixedly installed on the top of the base 11. A fixing rod 13 is bolted through the inner sidewall of the two sets of support plates 12. A rotating frame 15 for adjusting the angle of the display screen is rotatably mounted on the outer arc surface of the middle part of the fixing rod 13. A damping mechanism 2 is installed inside the rotating frame 15, and a mounting assembly 3 for connecting the display screen is installed on the top of the rotating frame 15. The damping mechanism 2 includes several sets of sliding rods 21, which are symmetrically and evenly distributed on both sides of the rotating frame 15. One end of each set of sliding rods 21 slides through the interior of the rotating frame 15 and is fitted with two sets of clamping plates 22. The other end of each set of sliding rods 21 is fixedly mounted with a limiting plate 24. The two sets of clamping plates 22 are symmetrically arranged on both sides of the fixing rod 13, and a set of springs 23 that provide clamping force to the clamping plates 22 are movably mounted on the outer arc surface of each set of sliding rods 21.

[0019] In use, the rotating assembly 1 serves as the basic support component of the entire rotating shaft structure, including a base 11, a support plate 12, a fixed rod 13, and a rotating frame 15. The base 11 is integrally formed from high-strength alloy material and has an anti-slip pad at the bottom. It can be fixed to a desktop or bracket with bolts to ensure the stability of the overall structure. Two sets of support plates 12 are symmetrically fixed on the top of the base 11. The support plates 12 are connected to the base 11 by welding or bolt fastening to ensure the connection strength. The rotating frame 15 is rotatably mounted on the outer arc surface of the middle part of the fixed rod 13. The rotating frame 15 adopts a hollow frame structure, and its inner diameter is adapted to the outer arc surface of the fixed rod 13, so that the rotating frame 15 can rotate flexibly around the fixed rod 13, thereby driving the monitor to achieve angle adjustment. The damping mechanism 2 is installed inside the rotating frame 15 and is the core component for the rotation positioning damping effect of the rotating frame 15. It includes a slide rod 21, a clamping plate 22, a spring 23, and a limiting plate 24. Several sets of slide rods 21 are symmetrically and evenly distributed on both sides of the rotating frame 15. The slide rods 21 slide and cooperate with the side wall of the rotating frame 15. One end of the slide rod 21 slides through the interior of the rotating frame 15 and is fixedly connected to the clamping plate 22. The other end is fixedly installed with the limiting plate 24. The diameter of the limiting plate 24 is larger than the diameter of the slide rod 21, which can prevent the slide rod 21 from slipping out of the rotating frame 15 and ensure the integrity of the structure. Two sets of clamping plates 22 are symmetrically arranged on both sides of the fixed rod 13. The outer arc surface of several sets of slide rods 21 is movably fitted with springs 23. When the springs 23 are in their natural state, they can push the clamping plates 22 tightly against the surface of the fixed rod 13 through elastic force, generating a stable friction force and forming a damping effect. This achieves the effect of automatic locking after the display screen is rotated and adjusted by external force. Compared with the damping structure at both ends of the rotating shaft, the damping force provided is more stable.

[0020] The two sets of clamping plates 22 are arranged in an arc shape, and the clamping surfaces of the two sets of clamping plates 22 are adapted to fit the outer arc surface of the fixing rod 13. The two sets of clamping plates 22 are arranged in an arc shape, and their clamping surfaces are adapted to fit the outer arc surface of the fixing rod 13, which increases the contact area between the clamping plates 22 and the fixing rod 13 and improves the stability of the damping effect.

[0021] The damping mechanism 2 also includes two sets of adjusting plates 25. Both sets of adjusting plates 25 are located between a set of clamping plates 22 and the inner side wall of the rotating frame 15. The two sets of adjusting plates 25 are slidably fitted onto the outer arc surface of the sliding rods 21 on both sides. One end of several sets of springs 23 is fixedly welded to one side of the clamping plate 22, and the other end of several sets of springs 23 is welded to one side of the adjusting plate 25. Both sides of the rotating frame 15 are threaded with a set of adjusting rods 26. One end of both sets of adjusting rods 26 passes through the interior of the rotating frame 15 and is rotatably connected to one side of the adjusting plate 25. Both sides of the rotating frame 15 are threaded with adjusting rods 26. One end of the adjusting rod 26 passes through the interior of the rotating frame 15 and is rotatably connected to one side of the adjusting plate 25 via a bearing. The other end extends to the exterior of the rotating frame 15 and is equipped with an adjusting knob. By rotating the adjusting rod 26, the adjusting plate 25 can be pushed to move axially along the slide rod 21, thereby changing the compression of the spring 23 and adjusting the clamping force of the clamping plate 22 on the fixed rod 13. Ultimately, this achieves the purpose of adjusting the magnitude of the damping force to meet the needs of different users.

[0022] Both sets of support plates 12 have a through-hole square groove 14 in the middle. The outer arc surfaces at both ends of the fixing rod 13 are set into rectangles that match the square grooves. The fixing rod 13 is bolted to the support plate 12 through the square groove 14. This rectangular fit structure can effectively prevent the fixing rod 13 from rotating in the support plate 12 and ensure the positioning stability of the fixing rod 13.

[0023] Mounting assembly 3 includes a fixing bracket 31 that is fixedly bolted to the top of the rotating frame 15. The top of the fixing bracket 31 has several sets of mounting holes 32 and slots 33. Mounting assembly 3 is used to connect the rotating shaft structure to the display. The mounting holes 32 are used to fasten the display to the fixing bracket 31 with bolts. The slots 33 can be positioned in conjunction with the protruding structure on the back of the display to improve the convenience of installation and the stability of connection.

[0024] A set of protective shells 4 are fitted and snapped into the upper and lower openings of the rotating frame 15. The two sets of protective shells 4 together with the rotating frame 15 form a rectangular closed structure. The protective shells 4 make the internal space of the rotating frame 15 relatively sealed, protecting the damping mechanism 2 inside the rotating frame 15 and preventing dust and debris from entering and affecting its working performance. The protective shells 4 are made of ABS engineering plastic, which has good wear resistance and impact resistance. They are also easy to disassemble, which facilitates subsequent maintenance and repair, and improves the overall aesthetics of the structure.

[0025] In practical use: First, fix the entire device to the designated position of the monitor using the base 11. Then, fix the monitor to the mounting bracket 31 through the mounting holes 32 and slots 33 of the mounting component 3 to achieve quick monitor installation. If the damping force is too large or too small, the user needs to adjust the damping force. Rotate the adjusting rod 26 clockwise, and the adjusting rod 26 pushes the adjusting plate 25 towards the clamping plate 22. The compression of the spring 23 increases, the clamping force of the clamping plate 22 on the fixing rod 13 increases, and the damping force increases. Rotate the adjusting rod 26 counterclockwise, and the adjusting plate 25 moves in the opposite direction under the action of the spring 23. The compression of the spring 23 decreases, the clamping force weakens, and the damping force decreases. When adjusting the angle, push the monitor to drive the rotating bracket 15 to rotate around the fixing rod 13. Since there is a stable friction between the clamping plate 22 and the fixing rod 13, a uniform damping feeling will be generated during the rotation. When the desired angle is reached, the damping force can keep the rotating bracket 15 in that position, thus fixing the monitor angle.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
