Description

Anti-nodding hinge device and electronic equipment

technical field

The utility model relates to the technical field of display equipment, in particular to an anti-nodding hinge device and electronic equipment.

Background technique

A display typically includes a base, a post fixed to the base, and a screen hinged to the top of the post. Generally, the hinged structure between the screen and the column relies on the maximum static friction between the components to achieve the positioning of the screen, that is, as long as the maximum static friction between the components of the hinged structure is greater than the gravity of the screen, the screen can be guaranteed to be released after the hand is released. can remain unchanged at a certain angle.

However, after a long time, the parts are prone to wear, or the effects of thermal expansion and contraction between the parts will cause the maximum static friction force to decrease. When the maximum static friction force is not enough to overcome the gravity of the screen, the screen will be in the gravity. Under the action, it naturally rotates downward, and it can no longer remain unchanged at a certain angle. The industry calls this the "nodding effect".

When the screen naturally rotates downward under the action of gravity, the screen becomes inclined downward, and it is difficult for people to observe the content on the screen while sitting in a chair. Therefore, it is necessary to improve the existing hinge structure to solve the problem that the "nodding effect" is prone to occur after the maximum static friction force is reduced.

Utility model content
