[0035] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0036] See also Figure 1-3The utility model provides a technical solution: a notebook computer hinge structure, including a mounting shaft 1, a mounting shaft 2, and a connecting shaft 3. The mounting shaft 1 and the mounting shaft 2 are both rotatably connected to the connecting shaft 3. A connecting sleeve 3 24 is rotatably mounted on the outer wall of the mounting shaft 2. The connecting sleeve 3 24 is fixedly mounted with a rotating sleeve 25 through a fixing frame 241. The rotating sleeve 25 is rotatably connected to the connecting shaft 3. A fixing ring 32 is fixedly mounted on the outer wall of the connecting shaft 3. A plurality of balls 321 are rotatably mounted on the fixing ring 32. Multiple balls 321 are evenly distributed on the fixed ring 32, and multiple mounting grooves 251 are opened on the inner wall of the rotating sleeve 25. Fixed beads 26 are slidably installed in the mounting grooves 251. A sealing gasket 261 is provided on the outer wall of the fixed beads 26. The mounting grooves 251 are filled with hydraulic oil 262. Multiple fixed beads 26 are evenly distributed on the inner wall of the mounting grooves 251. Two connecting frames 31 are rotatably installed on the outer wall of the connecting shaft 3. One end of the two connecting frames 31 is rotatably connected to the connecting shaft 3, and the other end is rotatably connected to the mounting shaft 1.
[0037] Among them, the rotation angle of the mounting shaft 2 is increased by the connecting shaft 3, so that the notebook screen can be rotated 360 degrees, and when the rotating sleeve 25 is rotated, the ball 321 squeezes the fixed bead 26, and the fixed bead 26 squeezes the hydraulic oil 262 through the sealing gasket 261. After the fixed bead 26 is no longer squeezed, the hydraulic oil 262 drives the fixed bead 26 to reset, thereby limiting the position of the fixed bead 26, so that the fixed bead 26 stays at the predetermined position when there is no external force.
[0038] The ends of the mounting shaft 1 and the mounting shaft 2 are respectively fixedly installed with a connecting sleeve 11 and a connecting sleeve 2 21, and the outer walls of the connecting sleeve 11 and the connecting sleeve 2 21 are respectively fixedly installed with a connecting plate 111 and a connecting plate 2 211, and the connecting plate 1 111 and the connecting plate 2 211 are respectively provided with a connecting hole 112 and a connecting hole 212.
[0039] The first connecting plate 111 and the second connecting plate 211 are fixed to the notebook housing and the display housing by passing the corresponding bolts through the first connecting hole 112 and the second connecting hole 212, so that the installation is more convenient.
[0040] The ends of the mounting shaft 1 and the mounting shaft 2 are respectively provided with a fixed end 12 and a fixed end 22 , and the fixed end 12 and the fixed end 2 are respectively provided with a threaded portion 121 and a threaded portion 221 .
[0041] Furthermore, the fixing end 12 and the fixing end 22 are threadedly connected to the threaded hole of the notebook housing and the display screen housing through the threaded portion 121 and the threaded portion 221, thereby fixing the installation shaft 1 and the installation shaft 2 2.
[0042] A fixing block 13 and a fixing block 23 are fixedly mounted on the mounting shaft 1 and the mounting shaft 2, respectively. The fixing block 13 and the fixing block 2, respectively, are provided with a first card slot 131 and a second card slot 231.
[0043] Specifically, the tool is used to engage the first card slot 131 and the second card slot 231, thereby driving the first fixing block 13 and the second fixing block 23 to rotate, thereby driving the first installation shaft 1 and the second installation shaft 2, making installation more convenient.
[0044] Both ends of the rotating sleeve 25 are provided with annular end covers, and the interior of the rotating sleeve 25 is filled with lubricating oil.
[0045] It should be noted that the annular end cover improves the sealing of the rotating sleeve 25, and a sealing ring is provided on the end cover to prevent the lubricating oil in the rotating sleeve 25 from leaking. At the same time, the lubricating oil lubricates the ball 321 and the fixed ball 26, thereby increasing their service life.
[0046] The working principle and use process of this utility model: please refer to Figure 1-3 The fixed end 12 and the fixed end 22 are threadedly connected to the threaded holes of the notebook shell or the display screen shell through the threaded portion 121 and the threaded portion 221, thereby fixing the mounting shaft 1 and the mounting shaft 2 2, and passing the corresponding connecting hole 112 and the connecting hole 212 through the matching bolts, so that the connecting plate 111 and the connecting plate 211 are fixed to the notebook shell or the display screen shell, and the connecting shaft 3 increases the rotation angle of the mounting shaft 2 2, so that the notebook screen can be rotated 360 degrees, and when the rotating sleeve 25 is rotated, the ball 321 squeezes the fixed bead 26, and the fixed bead 26 squeezes the hydraulic oil 262 through the sealing gasket 261. After the fixed bead 26 is no longer squeezed, the hydraulic oil 262 drives the fixed bead 26 to reset, thereby limiting the position of the fixed bead 26, so that the fixed bead 26 stays at the predetermined position when there is no external force.
[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
