Generally, the hinged structure between the screen and the upright posts realizes the positioning of the screen by means of the maximum static friction force between parts, namely, the screen can be kept unchanged at a certain angle after hands are loosened as long as the maximum static friction force between the parts of the hinged structure is larger than the gravity of the screen.
However, after a long time, the parts are easily worn, or the maximum static friction force is reduced due to the effects of expansion with heat and contraction with cold between the parts, and when the maximum static friction force is not enough to overcome the gravity of the screen, the screen will naturally rotate downwards under the action of gravity, and cannot be kept unchanged at a certain angle, which is called as the 'nodding effect' in the industry.
When the screen naturally rotates downward by gravity, the screen becomes inclined downward, and it is difficult for a person sitting on a chair to view the contents on the screen. Therefore, there is a need for improvement of the existing hinge structure to solve the problem that the maximum static friction force is reduced and the 'nodding effect' is easy to occur.

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Example one
Referring to fig. 1 to 4, the present embodiment provides a nodding-proof hinge device, which includes a pillar 1, a rotating member 2, and an elastic support piece 3. The top of the upright post 1 is provided with an arc-shaped surface 101. The rotating part 2 is tightly attached to the arc-shaped surface 101 and is rotatably connected with the arc-shaped surface 101, and a through groove 201 is formed in the middle of the rotating part 2. One end of the elastic support sheet 3 is fixedly connected with the upright post 1, and the other end extends into the through groove 201.
It should be noted that, at the beginning, the maximum static friction force between the rotating element 2 and the arc-shaped surface 101 is large, the angle between the rotating element 2 and the column 1 can be changed by rotating the rotating element 2, and since the maximum static friction force is large, after the hand is loosened, the maximum static friction force can overcome the influence of gravity and the elastic force of the elastic support piece 3 on the rotating element 2, and the rotating element 2 is kept at a fixed position. After the maximum static friction force between the rotating part 2 and the arc-shaped surface 101 is reduced, the rotating part 2 automatically rotates downwards under the action of gravity, and when the rotating part rotates to the upper edge of the through groove 201 and is blocked by the elastic supporting pieces 3, the elastic supporting pieces 3 provide upward supporting force for the rotating part 2, so that the rotating part 2 cannot continuously rotate downwards, and the traditional 'nodding effect' after the maximum static friction force is reduced is overcome.
It is understood that the thickness or material of the elastic support sheet 3 may be adjusted according to design requirements to adjust the elastic force provided by the elastic support sheet 3, so that the rotating member 2 can be maintained at a predetermined angle and position after the maximum static friction force between the rotating member 2 and the arc-shaped surface 101 is reduced.
The anti-nodding hinge device further comprises an inner friction plate 4 and an outer friction plate 5. The inner friction plate 4 is located between the rotating member 2 and the column 1, and is used for increasing the maximum static friction force when the rotating member 2 is static. The outer friction plate 5 is located on one side of the rotating member 2 away from the inner friction plate 4 and is used for increasing the maximum static friction force when the rotating member 2 is static.
It should be noted that the friction plate is an assembly composed of a core plate and a friction lining or a friction material layer, and can effectively increase the friction coefficient and provide a certain damping effect, so as to improve the maximum static friction force when the rotating member 2 is stationary, and ensure that the maximum static friction force can enable the rotating member 2 to overcome the influence caused by gravity and the elasticity of the elastic support sheet 3, and to be kept in a fixed position. The simultaneous use of the inner friction plates 4 and the outer friction plates 5 can greatly increase the maximum static friction force.
Preferably, one side of the inner friction plate 4 and one side of the outer friction plate 5, which are close to the rotating member 2, are both provided with a plurality of first longitudinal anti-slip bosses 401, and positions of the rotating member 2, which correspond to the first longitudinal anti-slip bosses 401, are both provided with second longitudinal anti-slip bosses 202 which are abutted against the corresponding first longitudinal anti-slip bosses 401.
It will be appreciated that the first longitudinal rib 401 and the second longitudinal rib 202 abut against each other, which greatly increases the maximum static friction force of the rotating member 2 at rest.
In this embodiment, the arc-shaped surface 101 is provided with a first accommodating groove 102, and the inner friction plate 4 is located in the first accommodating groove 102; a plurality of positioning bosses 104 protrude from the bottom of the first accommodating groove 102, positioning through grooves are formed in the positions of the inner friction plate 4 and the outer friction plate 5 corresponding to the positioning bosses 104, and the positioning bosses 104 penetrate through the positioning through grooves.
Further, a second receiving groove 103 is formed at the bottom of the first receiving groove 102, and the elastic support piece 3 is fixed in the second receiving groove 103.
Specifically, the first receiving groove 102 may facilitate positioning of the inner friction plate 4, the positioning boss 104 may facilitate positioning of the outer friction plate 5, and the second receiving groove 103 may facilitate positioning of the elastic support plate 3.
Optionally, the rotating member 2 is provided with a longitudinal strip-shaped through slot 203 for the positioning boss 104 to pass through.
Specifically, the longitudinal strip-shaped through groove 203 can ensure that the rotating member 2 does not interfere with the positioning boss 104 when rotating.
Further, the anti-nodding hinge device further comprises a clamping plate 6, wherein the clamping plate 6 is located on one side, away from the rotating part 2, of the outer friction plate 5 and fixedly connected with the positioning boss 104.
Specifically, the clamping plate 6 and the upright post 1 clamp the inner friction plate 4, the rotating member 2 and the outer friction plate 5, so that the inner friction plate 4 and the outer friction plate 5 can be kept fixed, and the maximum static friction force of the rotating member 2 when the rotating member is static can be increased.
Example two
The embodiment also provides an electronic device, which comprises any one of the nodding-head-prevention hinge devices provided by the first embodiment and has the same functions and technical effects.
Referring to fig. 1, further, the electronic device further includes a screen and a base 7. The screen is fixedly connected with the rotating part 2; the base 7 is fixedly connected to the bottom of the upright post 1.
It should be noted that, at the beginning, the maximum static friction force between the rotating member 2 and the arc-shaped surface 101 is relatively large, and the rotation of the rotating member 2 can change the angle between the rotating member 2 and the column 1, so as to change the angle of the screen. After the maximum static friction force between the rotating part 2 and the arc-shaped surface 101 is reduced, the screen automatically rotates downwards under the action of gravity, and when the screen rotates to the position where the upper edge of the through groove 201 is blocked by the elastic supporting pieces 3, the elastic supporting pieces 3 provide upward supporting force for the rotating part 2, so that the screen cannot continuously rotate downwards, and the 'nodding effect' after the traditional maximum static friction force is reduced is overcome.
Preferably, the electronic device may be a display, a television, or the like.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
