Referring to fig. 1 to 4, a screen hinge structure according to an embodiment of the present invention is installed on a notebook computer host to connect the notebook computer host and a display screen. The utility model also protects a notebook computer which comprises the screen hinge structure.

In the present embodiment, the screen hinge structure includes a fixed plate 10, a movable plate 20, a rotation shaft 30, an adjusting member 40, and a friction member 50. The fixing plate 10 is used for fixing with a host of a notebook computer, and the fixing plate 10 is rotatably connected with the rotating shaft 30; the movable plate 20 is rotatably connected with the rotating shaft 30; the adjusting member 40 is connected with the movable plate 20; the friction piece 50 is axially fixedly connected with the adjusting end 41 of the adjusting piece 40 and rotates along with the rotation of the adjusting piece 40; when the friction member 50 rotates a certain angle, it contacts the rotating shaft 30 to increase the friction force of the movable plate 20 relative to the rotating shaft 30. This screen hinge structure reasonable in design, adjustable torsion size, the easy operation of adjusting torsion, the installation of being convenient for.

The fixing plate 10 includes a mounting portion 11 and first boss portions 12 bent and extended from the same side of both ends of the mounting portion 11. The mounting portion 11 is a flat plate, and a mounting hole 110 is formed in the mounting portion 11 for fixedly connecting a host of a notebook computer through a fixing member. Each first boss portion 12 is tubular. In the present embodiment, the fixing plate 10 is formed by integrally bending a metal sheet.

The movable plate 20 includes a connecting portion 21, a second sleeve portion 22 extending from the same side of two ends of the connecting portion, and a locking portion 23 connected to the second sleeve portion 22. The cross section of the connecting part 21 is L-shaped, the connecting part 21 is provided with connecting holes 210 and a central hole 211 positioned between the two connecting holes 210; the connecting hole 210 is used for fixedly connecting with the screen of the notebook computer, and the central hole 211 is used for connecting with the friction member 50. The cross section of the second collar portion 22 is disposed in a semicircular shape, and a gap is formed in the middle. The position-locking part 23 is provided with a position-locking groove 230 for the friction member 50 to be inserted; the retaining groove is arranged in a concave shape with a low middle and high two sides for the friction piece 50 to pass through.

The rotating shaft 30 is cylindrically formed, and has a length greater than the axial length of the fixing plate 10, and both ends thereof are provided with thread grooves 31; the shaft 30 passes through the first sleeve portion 12 and the second sleeve portion 22 in this order. The washer 32 is coupled to the screw groove 31 to fix the position of the rotation shaft 30.

The adjusting member 40 includes an adjusting end 41 and a connecting end 42, and the adjusting member 40 is rotatably connected to the movable plate 20 through a friction member 50. In the present embodiment, the adjusting end 41 is disposed in a hexagonal prism shape, and the adjusting end 41 can be rotated by a wrench to change the position of the friction member 50 in the detent groove 230; in addition, the end surface of the adjusting end 41 is provided with a driving groove for driving a screwdriver. The connecting end 42 is a threaded end that is threadedly coupled to a nut.

The friction member 50 is disposed in a sheet shape, and the friction member 50 is provided with a linkage hole 51, and the linkage hole 51 is used for the adjuster 40 to pass through and is rotatably connected with the movable plate 20. In this embodiment, the linkage hole 51 is formed in an oval shape, and the cross section of the middle portion of the adjusting member 40 is formed corresponding to the shape of the linkage hole 51, so that the friction member 50 can be driven to rotate when the adjusting member 40 rotates. The friction member 50 passes through the locking groove 230, and the friction member 50 is frictionally coupled to the rotation shaft 30 after the adjustment member 40 rotates a certain angle.

When the friction member 50 passes through the locking groove 230, the friction member 50 and the second sleeve portion 22 simultaneously clamp the rotating shaft 30 and generate friction force; at this time, when the screen drives the movable plate 20 to rotate to a predetermined angle, the screen and the movable plate 20 are positioned at the predetermined position. Since the locking groove 230 is in a concave shape with a low middle and high sides, the friction force of the friction member 50 is the largest when the friction member is located in the middle of the locking groove 230, and the friction force on the two sides of the locking groove 230 is relatively smaller, so that the user can adjust the torque force according to the requirement. For example, the adjusting member 40 is rotated to move the friction member 50 away from the middle of the locking slot 230, so that the friction force between the friction member 50 and the rotating shaft 30 is reduced, and the torsion force of the hinge is reduced.
