When external force is applied to rotate the display screen 16, the plane four-bar mechanism has only one degree of freedom, the support 1 and the first connecting rod 14 can perform relative motion, when the plane four-bar mechanism rotates to any angle, when the external force is removed, the gravity of the display screen 16 is counteracted with the force generated by the long torsion spring 2/the short torsion spring 4, the force generated by the compression spring 7 and the friction force generated by the friction plate 3, at the moment, the stress of the whole system is balanced, and the display screen 16 is kept in a static state, so that hovering of the display screen 16 is realized.
The following examples are given by way of illustration of detailed embodiments and specific procedures based on the technical scheme of the present invention, but the scope of the present invention is not limited to the following examples. The technical means adopted in the following examples are conventional technical means unless otherwise specified.
[ Example ]
As shown in fig. 6, the display screen 16 is fixedly connected with the display screen connecting plate 5 by bolts. At this point the display screen 16 is in an upright position (perpendicular to the horizontal plane) and the system is balanced under the weight of the display screen 16 and the torque provided by the short torsion spring 4.
One end of the short torsion spring 4 is fixed on the display screen connecting plate 5 through a second pressing block 13. One end of the rotating shaft extends into a sliding groove on the second fixing flange 19, and the rotating shaft 6 on the support is fixedly connected with the support 1 through bolts. A limiting plate is arranged in a chute on the second fixing flange 19 to realize single-side sealing, and when the display screen 16 rotates anticlockwise by taking the axis of the rotating shaft 6 on the bracket as the center, the limiting plate in the chute plays a limiting role on the rotation of the short torsion spring 4 to generate torsion moment; when rotating clockwise, the short torsion spring 4 slides along the chute, and no torsion moment is generated. In the invention, the short torsion spring unit mainly plays a limiting role, so that the display screen 16 is kept in a vertical state and cannot rotate anticlockwise (the anticlockwise rotation of the display screen does not accord with the conventional use habit), and can only rotate clockwise.
When the user adjusts the angle of the display screen 16, an external force can be applied to the display screen 16, so that the display screen 16 rotates clockwise (according to the position shown in fig. 6) around the upper rotating shaft 6 of the bracket by an angle, and at this time, the lower supporting point of the bracket 1 rotates anticlockwise by a corresponding angle by taking the axis of the lower rotating shaft 8 of the bracket as the center; as shown in fig. 1, since one end of the long torsion spring 2 is fixedly connected to the display screen connecting plate 5 through the first pressing block 12, and the other end is fixed in the mounting groove of the first fixing flange 18, the upper rotating shaft 6 of the bracket is fixedly connected with the bracket 1 through bolts, and when the display screen 16 and the bracket 1 perform relative movement, the long torsion spring 2 generates a torsion moment, and the display screen 16 is prevented from rotating clockwise by the torsion moment.
As shown in fig. 5, the bracket 1 is fixedly connected with the bracket lower rotating shaft 8 through bolts, one end of the compression spring 7 is fixed on the main machine base 9, the other end is fixed with the spring pressing rod 11, the spring pressing rod 11 is hinged with the shaft sleeve 10 on the bracket lower rotating shaft 8 to form a rotating pair, and the shaft sleeve 10 is fixedly connected with the bracket lower rotating shaft 8. The host base 9 and the host 17 are fixedly connected together through bolts, and in practical application, the host 17 and the host base 9 are stationary, so that the host base 9 is fixed as a frame of the mechanism in a planar four-bar mechanism. When the display screen 16 rotates clockwise around the axis of the upper rotating shaft 6 of the bracket, the lower supporting point of the bracket 1 rotates anticlockwise around the axis of the lower rotating shaft 8 of the bracket because of only one degree of freedom of the planar four-bar mechanism, and drives the lower rotating shaft 8 of the bracket and the shaft sleeve 10 on the lower rotating shaft to rotate, so that the compression spring 7 is compressed, and the generated moment is used for preventing the bracket 1 from rotating anticlockwise, namely preventing the display screen 16 from rotating clockwise.
As shown in fig. 1, the friction plate 3 is sleeved on the rotating shaft 6 on the bracket, the friction plate 3 and the rotating shaft form a friction pair, one opening end of the friction plate 3 is fixed on the display screen connecting plate 5 through the connecting plate and the bolt, the other opening end of the friction plate passes through the two opening ends of the friction plate 3 to be clamped on the rotating shaft 6 on the bracket through the adjusting bolt, and the magnitude of friction damping between the friction plate 3 and the rotating shaft 6 on the bracket can be adjusted through the adjusting bolt. This friction is always used to prevent the display screen 16 from rotating, whether the display screen 16 rotates clockwise or counter-clockwise.
When the user adjusts the display screen 16 to a proper angle and removes the external force, the whole system remains static, namely the moment generated by the gravity of the display screen 16, the moment generated by the long torsion spring 2, the moment generated by the compression spring 7, and the friction moment generated by the friction plate 3 = zero. The moment generated by the gravity of the display screen 16, the moment generated by the long torsion spring 2 and the moment generated by the compression spring 7 are all changed according to different rotation angles, but can also be calculated. Since the friction torque generated by the friction plate 3 is a range of values, it can be used to cancel the resultant of the addition of the three torques. After the offset, the resultant force is zero, so that the display screen 16 can be stopped at any angle, and the use requirement of hovering of the display screen is met.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
