As shown in fig. 1, after the front edge of the screen end 14 is opened by hand by 0.5-2 degrees, the screen end 14 is automatically opened to a set angle.

As shown in fig. 2, the screen end 14 can be automatically opened to a set angle without using hands in a closed state by means of touch, fingerprint, voice control and other instructions.

As shown in figure 3, the hinge of the invention is composed of a left hinge 2 and a right hinge 2, the middle parts of the left hinge and the right hinge are connected by a straight torsion spring rod 3, and torsion force is generated. The torsion spring rod 3 is a straight spring wire, two ends of the torsion spring rod are respectively connected with hinges at two ends, and the hinges are customized hinges. The left and right hinges 2 are fixed to the screen end 14 and the system end 15 of the notebook computer, respectively, in the same manner as the conventional hinges. The middle torsion spring rod 3 line is connected with the hinges at the two sides in a penetrating way, and the position on the machine shell needs to be avoided, and the torsion spring rod 3 line can be arranged at the screen end 14 or the system end 15.

The automatic opening angle of the notebook screen end 14 is realized by a hinge, and the automatic opening angle can be set to be stopped at an arbitrarily set angle which does not exceed 180 degrees.

Example 1

The left hinge 1 and the right hinge 2 can be matched in a wrapping type structure, specifically, the automatic opening angle of the notebook computer is set to be theta degrees, the hinge has no torsion force in the angle state of 0-theta degrees, and the hinge is automatically opened and provided by the torsion spring rod 3. The circle of the movable frame A5 is made into a small plane 40, and the axle center column A6 is kept away, so that no torsion is generated during rotation. The fixed frame A4 and the movable frame A5 can rotate freely, the torsion starts to be increased gradually when the movable frame A5 rotates to 10 degrees to 15 degrees before theta degrees, finally the torsion reaches the maximum at 10 degrees to 15 degrees after theta degrees, and then the movable frame A5 rotates backwards, so that the torsion is stable.

The movable frame A5 and the axle center column B6 have no interference at 0-theta degrees, the wrapping circle of the movable frame is a small plane, and the axle center column is kept away, so that no torsion is generated during rotation. The small plane of the wrapping circle of the movable frame is contacted with the axis when the movable frame rotates to the angle of theta from 10 degrees to 15 degrees before the angle of theta, the small plane of the wrapping circle of the movable frame is completely contacted when the movable frame rotates to the angle of theta, the torsion is gradually increased, finally, the maximum is reached at the angle of 10 degrees to 15 degrees after the angle of theta, and the torsion starts to be stable.

The automatic starting angle and strength of the notebook computer can be adjusted by adjusting the matching angle of the shaft sleeve and the shaft center and the matching angle of the movable frame facet and the shaft center.

Example 2

The concave-cam spring plate type hinge structure consists of a left hinge 1, a right hinge 2 and a torsion spring rod 3. In this case, the left hinge further includes a washer a21, a concave wheel a22, a cam a23, a spring plate 24, a washer B25 and a nut 26 which are sequentially fitted over the spindle post A6, so that as shown in the drawing, the spindle sleeve A7 is rotationally fitted with the spindle sleeve A7 through a washer a21, a concave wheel a22, a cam a23, a spring plate 24, a washer B25 and a nut 26, and the right hinge further includes a washer C30, a concave wheel B31, a cam B32, a spring plate 33, a washer D34 and a nut 35 which are sequentially fitted over the spindle post B10, so that as shown in the drawing, the spindle sleeve B11 is rotationally fitted through a washer C30, a concave wheel B31, a cam B32, a spring plate 33, a washer D34 and a nut 35 which are known to those skilled in the art, and the manner of rotationally coupling thereof is understood to be an extensible embodiment by those skilled in the art,

the left hinge and the right hinge can be matched by adopting a concave-convex wheel spring sheet type hinge structure, specifically, the automatic opening angle of the notebook is set to be theta degrees, the hinge has no torsion in the angle range of 0-theta degrees, and the hinge is realized by the concave wheel and the cam. The fixed frame and the movable frame can rotate freely, the torsion is gradually increased from 10 degrees to 15 degrees before the fixed frame rotates to theta degrees, finally the torsion of 5 degrees to 10 degrees after the theta degrees reaches the maximum, and the fixed frame and the movable frame rotate backwards, so that the torsion is stable.

The concave wheel is matched with the cam in angle, and the hinge is set to be provided with resilience force by the torsion spring rod 3 line within the angle range of 0-theta degrees. At 0 degree, the cam has no resistance in the concave wheel groove, and no torque force exists until the front 10-15 degrees of theta degrees along with the rotation of the hinge.

And at the front 10-15 degrees of theta, the cam starts to climb in the groove of the concave wheel, and the torsion starts to climb.

After the torsion of 5-10 degrees behind the theta degree reaches the maximum, the hinge rotates backwards, the torsion is stable, and then the hinge is like a conventional hinge.
