Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.
The embodiment is as follows:
as shown in fig. 1-4, an automatic turning-on shaft for a computer comprises a display end 10 and a system end 20, wherein a shaft member 30 is arranged between the display end 10 and the system end 20; opposite end surfaces of the display end 10 and the system end 20 are also provided with an opposite magnetic attraction block to help the display end and the system end to be closed; the rotating shaft element 30 comprises a fixed frame 301, a left torsion spring wire 302 and a right torsion spring wire 303 which are sleeved at two ends of the fixed frame 301, and hinge elements 304 are arranged at the end parts of the left torsion spring wire 302 and the right torsion spring wire 303; the hinge member 304 includes a movable hinge bracket 3041 and a fixed hinge bracket 3042; the movable hinge bracket 3041 and the fixed hinge bracket 3042 are fixed on the display end 10 and the system end 20, respectively; the left torsion spring wire 302 and the right torsion spring wire 303 are respectively connected with the movable hinge frame 3041 corresponding to each other;
when the automatic rotating shaft is used, only a slight upward force needs to be manually applied to the display end 10, and the force enables the display end 10 to open a smaller angle, for example, 3 degrees, because the left torsion spring wire 302 and the right torsion spring wire 303 are respectively connected with the respective movable hinge brackets 3041, and the movable hinge brackets 3041 are on the display end 10, when the display end 10 opens a small angle, the magnetic attraction force between the display end 10 and the system end 20 is smaller than the torque force of the left torsion spring wire 302 and the right torsion spring wire 303, so that the display end 10 is driven to rotate upward by the torque force until the display end 10 rotates to a limit angle, thereby realizing the automatic opening of the display end 10, solving the problem that a user can still automatically rotate the display screen to a proper working angle when the user is inconvenient to open the screen;
as shown in fig. 4, the inner sides of the extending plates of the movable hinge bracket 3041 are respectively sleeved with an axis 3048, the outer side of the axis 3048 is sequentially provided with an adjusting nut 3044, a gasket 3045, an elastic sheet 3043, a fixing sheet 3046 and a driving gear 3047, one end of the fixed hinge bracket 3042 is provided with a shaft 30413, the shaft 30413 passes through the extending plate of the movable hinge bracket 3041, and the outer side of the shaft 30413 is sequentially sleeved with a fixing nut 3049, a gasket 3045, an elastic sheet 3043 and a driven gear 30412;
the rotation speed of the display end 10 can be controlled by screwing the adjusting nut 3044, for example, the adjusting nut 3044 rotates towards the direction of pressing the elastic sheet 3043, the elastic sheet 3043 is pressed by the adjusting nut 3044, the friction resistance between the elastic sheet 3043 and the axis 3048 is increased, under the same torque force applied by the torsion spring wire, the rotation speed of the axis 3048 is slower, the rotation angle is smaller, and the adjusting nut 3044 rotates towards the direction of loosening the elastic sheet 3043, the elastic sheet 3043 is loosened, the friction resistance of the axis 3048 is smaller during rotation, and under the same torque force, the rotation speed of the axis 3048 is faster, and the rotation angle is larger;
as shown in fig. 2, the inner side of the fixed hinge frame 3042 is provided with a position-avoiding groove corresponding to the left torsion spring wire 302 and the right torsion spring wire 303, so that the left torsion spring wire 302 and the right torsion spring wire 303 can be conveniently clamped on the fixed hinge frame 3042 through the position-avoiding groove;
as shown in fig. 4-5, a cam 30410 and a concave wheel 30411 are further disposed outside the shaft body 30413 and between the elastic sheet 3043 and the driven gear 30412; the concave wheel 30411 is embedded in the inner side of the movable hinge frame 3041, two sets of bumps are integrally formed at the end of the cam 30410, grooves are formed on the outer surface of the end of the concave wheel 30411 corresponding to the two bumps, and the cam 30410 and the concave wheel 30411 are matched with each other by the bumps and the grooves;
when the display end 10 is rotated by the torsion spring force until the projection of the cam 30410 rotates to the groove of the concave wheel 30411, the display end 10 reaches the so-called limit angle because the torque force cannot rotate the projection out of the edge of the groove, and manual assistance is required for rotation.
The working principle is as follows: when the automatic rotating shaft is used, the display end 10 is tilted up slightly manually, so that the magnetic attraction of the magnetic blocks between the display end 10 and the system end 20 is lost or weakened, then the torque force generated by the left torsion spring wire 302 and the right torsion spring wire 303 drives the movable hinge frame 3041 to rotate, since the movable hinge frame 3041 and the display end 10 are connected to each other, the display end 10 is driven to move up, the movable hinge frame 3041 drives the shaft center 3048 at the inner side thereof to rotate, and the driving gear 3047 is arranged on the shaft center 3048, so the driving gear 3047 rotates together with the movable hinge frame 3047, and the driving gear 3047 is further engaged with the driven gear 30412 on the shaft body 30413, so that the driving gear 3047 rotates the driven gear 30412, the shaft body 30412 drives the shaft body 30413 to rotate, so that the cam 30410 on the shaft body 13 rotates, because the concave wheel 30411 is fixedly embedded in the movable hinge frame 3041, so that the convex block of the display end 30410 rotates along the concave wheel 30411 until the edge of the motion groove, the convex block of the concave wheel 30411, and the display end 10 moves to the limit position if the display end needs to be moved manually.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
