Description

Technical Field

[0001] This invention relates to the field of damping shaft technology, specifically a damping shaft structure with multiple hinges and multi-angle adjustment. Background Technology

[0002] A damped hinge is a special hinge design that uses friction or liquid damping to generate resistance to control the rotation speed. It is mainly used in electronic devices such as laptops to achieve smooth opening and closing of the screen. Its core is to slow down the rotation speed through damping materials or structures, provide appropriate resistance feedback, and ensure that the screen opening and closing process is smooth and quiet.

[0003] Laptops require frequent opening and closing of the screen, which operates via a damping hinge. Over time, the components in the damping hinge may wear down and develop gaps, causing the hinge to loosen and affecting the stability of the screen during opening and closing. Summary of the Invention

[0013] Furthermore, the stabilizing component includes a cylindrical rod, an end of which is fixedly connected to a circular hole frame, a vertical rod slidably connected to the inner wall of the circular hole frame, the top of the vertical rod being fixedly connected to the top of the inner wall of the shaft core, a spring rod being fixedly connected to the top of the cylindrical rod, a friction plate being fixedly connected to the top of the spring rod, and a grooved extrusion disc being fixedly connected to the surface of the rotating rod.

[0014] Furthermore, the surface of the bent plate contacts the inner wall of the C-shaped hole, the end of the bent plate away from the groove extends into the interior of the shaft core, the end of the rotating rod away from the bent plate is rotatably connected to the inner wall of the shaft core, the rotating rod is located at the inner center of the shaft core, and the bottom of the plumb line extends to below the bottom of the circular hole frame.

[0015] Furthermore, the surface of the friction plate contacts the inner wall of the through hole, the end of the friction plate away from the elastic rod contacts the inner wall of the rotating wheel, the surface of the cylindrical rod contacts the inner wall of the grooved extrusion disc, and the surface of the grooved extrusion disc is provided with a distance from the inner wall of the shaft core.

[0016] Furthermore, the lubrication component includes a tripod, with an extrusion plate fixedly connected to the bottom of the tripod, a spring fixedly connected to the top of the storage rack, the top of the spring fixedly connected to the tripod, a circular plate fixedly connected to the inner wall of the storage rack, a screen feed rack fixedly connected to the top of the circular plate, a transmission pipe connected to the bottom of the screen feed rack, the end of the transmission pipe away from the screen feed rack passing through the mounting rod and extending to the surface of the rotary wheel, a connecting plate fixedly connected to the surface of the bending plate, and a triangular extrusion frame fixedly connected to the end of the connecting plate away from the bending plate.

[0017] Furthermore, the bottom of the tripod penetrates through the storage rack and extends into the interior of the storage rack, and the surface of the extrusion plate contacts the inner wall of the storage rack.

[0018] Furthermore, the extrusion plate is located above the circular plate, the surface of the triangular extrusion frame is in contact with the inner wall of the storage rack, and the triangular extrusion frame is located below the interior of the mounting rod.

[0019] The present invention has the following beneficial effects:

[0020] After the mounting plate is installed, the mounting rod is fixed and limited by the mounting plate, and the connecting plate is installed together with the display screen. When the display screen is opened, the display screen drives the rotating wheel to rotate on the surface of the shaft core through the connecting plate. After the nut is threaded onto the surface of the shaft core, the nut squeezes the washer through the compression ring, and the washer squeezes the rotating wheel through the contact plate. The friction between the contact plate and the washer forms damping, and the damping limits the rotating wheel, so that the display screen can stay in any position, improving the comfort of using the display screen. A compression ring is set inside the annular groove, which isolates the washer and the nut, preventing the nut from rotating due to the friction between the washer and the contact plate, which would cause it to loosen. This improves the stability of the rotating wheel supporting the connecting plate.

[0021] In this invention, the contact disc rotates, causing the bent plate to rotate via a groove. The bent plate, in turn, causes the rotating rod to rotate inside the shaft. The rotating rod, in turn, causes the grooved pressing disc to press against the cylindrical rod. Under pressure, the cylindrical rod moves upward and pushes the elastic rod. The elastic rod uses this pressure to push the friction plate to press and fix the rotating wheel, thereby increasing the stability of the rotating wheel during operation. When the cylindrical rod moves to the inner wall of the shaft, the surface of the grooved pressing disc contacts the surface of the cylindrical rod, positioning it on the inner wall of the shaft. This keeps the cylindrical rod pressing against the elastic rod. In this state, the elastic rod pushes the friction plate to press and limit the rotating wheel. When loosening occurs between the rotating wheel and the gasket, the friction plate presses and fixes the rotating wheel with pressure, preventing the rotating wheel from loosening due to insufficient friction.

[0022] This invention requires adding damping grease to the surface of the rotating wheel, pushing the display screen to open to a larger angle. At this time, the rotating wheel will drive the connecting plate to rotate inside the mounting rod via the bending plate. When the connecting plate rotates, it pushes the triangular extrusion frame to extrude the triangular frame. After the triangular frame is under pressure, it pushes the extrusion plate downward. When the extrusion plate moves downward, it pushes the damping grease in the storage rack into the inside of the screen feed rack. The damping grease is then applied to the surface of the rotating wheel through the transmission pipe. Excess damping grease will fall into the inside of the semi-circular cover. When the rotating wheel reciprocates on the surface of the shaft, the damping grease on the surface and the damping grease in the semi-circular cover will adhere to the surface of the rotating wheel and be applied to its surface as the rotating wheel rotates. Regularly adding damping grease will make the rotating wheel move more smoothly, avoid the components from shifting or making abnormal noise due to inertia or vibration, avoid the increased wear caused by insufficient damping grease in the rotating wheel, and reduce friction damage between the rotating wheel and the gasket.

[0023] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The end of the contact disc 19 away from the rotating wheel 17 contacts the end of the mounting rod 1. The surface of the gasket 18 contacts the surface of the contact disc 19. A compression ring 16 is provided inside the annular groove 15. The compression ring 16 isolates the gasket 18 and the nut 12, preventing the gasket 18 from rotating and causing the nut 12 to rotate due to friction with the contact disc 19, thus improving the stability of the rotating wheel 17 supporting the connecting plate 13.

When the bending plate 20 rotates, it drives the rotating rod 21 to rotate inside the shaft core 6. When the rotating rod 21 rotates, it drives the grooved pressing disc 27 to press the cylindrical rod 22. After being subjected to pressure, the cylindrical rod 22 will move upward and push the spring rod 26. The spring rod 26 uses pressure to push the friction plate 23 to press and fix the rotating wheel 17, thereby increasing the stability of the rotating wheel 17 during operation.

[0045] The surface of the bent plate 20 contacts the inner wall of the C-shaped hole 11. The end of the bent plate 20 away from the groove 14 extends into the interior of the shaft core 6.

The bottom of the vertical rod 24 extends to the bottom of the round hole frame 25. When the cylindrical rod 22 moves to the inner wall of the shaft core 6, the surface of the groove extrusion plate 27 will contact the surface of the cylindrical rod 22. The groove extrusion plate 27 is used to position the cylindrical rod 22 at the inner wall of the shaft core 6, so that the cylindrical rod 22 is kept in a state of extruding the elastic rod 26. In this state, the elastic rod 26 pushes the friction plate 23 to extrude and limit the rotating wheel 17.

A connecting plate 40 is fixedly connected to the surface of the curved plate 20, and one end of the connecting plate 40 away from the curved plate 20 is fixedly connected to... With the triangular extrusion frame 39, when damping grease needs to be added to the surface of the rotating wheel 17, the display screen is pushed to open to a larger angle. At this time, the rotating wheel 17 will drive the connecting plate 40 to rotate inside the mounting rod 1 through the bending plate 20. When the connecting plate 40 rotates, it pushes the triangular extrusion frame 39 to extrude the triangular frame 34. After the triangular frame 34 is under pressure, it pushes the extrusion plate 36 to move downward. When the extrusion plate 36 moves downward, it will push the damping grease in the storage rack 32 into the inside of the screen feed rack 38. The damping grease is then applied to the surface of the rotating wheel 17 through the transmission pipe 33. Excess damping grease will fall into the inside of the semi-circular cover 3.

[0048] The bottom of the tripod 34 penetrates through the storage rack 32 and extends into the interior of the storage rack 32. The surface of the extrusion plate 36 contacts the inner wall of the storage rack 32. When the roller 17 reciprocates on the surface of the shaft core 6, the damping grease on the surface and the damping grease in the semi-circular cover 3 will adhere to the surface of the roller 17 and be applied to its surface as the roller 17 rotates.

When the display screen is opened, the display screen drives the rotating wheel 17 to rotate on the surface of the shaft core 6 through the connecting plate 13. After the nut 12 is threaded onto the surface of the shaft core 6, the nut 12 compresses the washer 18 through the compression ring 16. The washer 18 compresses the rotating wheel 17 through the contact plate 19. The friction between the contact plate 19 and the washer 18 forms damping, which limits the rotation wheel 17, allowing the display screen to stay in any position and improving the comfort of using the display screen. The compression ring 16 is provided inside the annular groove 15, and the compression ring 16 compresses the washer 18. The contact plate 18 is isolated from the nut 12 to prevent the nut 12 from rotating due to friction between the gasket 18 and the contact plate 19, thus improving the stability of the rotating wheel 17 supporting the connecting plate 13. When the contact plate 19 rotates, it drives the bent plate 20 to rotate through the groove 14. When the bent plate 20 rotates, it drives the rotating rod 21 to rotate inside the shaft core 6. When the rotating rod 21 rotates, it drives the grooved pressing plate 27 to press the cylindrical rod 22. After being subjected to pressure, the cylindrical rod 22 will move upward and push the elastic rod 26. The elastic rod 26 uses pressure to push the friction plate 23 to press and fix the rotating wheel 17, thereby increasing the stability of the rotating wheel 17 during operation. When the cylindrical rod 22 moves to the inner wall of the shaft core 6, the surface of the grooved pressing plate 27 will contact the cylindrical rod 22. 2. Surface contact, using the grooved extrusion plate 27 to position the cylindrical rod 22 on the inner wall of the shaft core 6, so that the cylindrical rod 22 maintains a state of extrusion against the elastic rod 26. In this state, the elastic rod 26 pushes the friction plate 23 to extrude and limit the rotating wheel 17. When the rotating wheel 17 and the gasket 18 become loose, the friction plate 23 will press and fix the rotating wheel 17 through pressure to prevent the rotating wheel 17 from becoming loose due to insufficient friction. When damping grease needs to be added to the surface of the rotating wheel 17, push the display screen to open to a larger angle. At this time, the rotating wheel 17 will drive the connecting plate 40 to rotate inside the mounting rod 1 through the bending plate 20. When the connecting plate 40 rotates, it pushes the triangular extrusion bracket 39 to extrude against the triangular bracket 34. After being subjected to pressure, the extrusion disc 36 is pushed downward. When the extrusion disc 36 moves downward, it pushes the damping grease in the storage rack 32 into the inside of the screen feed rack 38. The damping grease is then applied to the surface of the rotor 17 through the transmission pipe 33. Excess damping grease will fall into the inside of the semi-circular cover 3. When the rotor 17 reciprocates on the surface of the shaft core 6, the damping grease on the surface and the damping grease in the semi-circular cover 3 will adhere to the surface of the rotor 17 and be applied to its surface as the rotor 17 rotates. Regularly adding damping grease will make the rotor 17 move more smoothly, avoid the parts from shifting or making abnormal noise due to inertia or vibration, avoid the rotor 17 from being worn due to insufficient damping grease, and reduce the friction damage between the rotor 17 and the gasket 18.
