Display hinge device

Abstract

The disclosed display comprises a display main body for outputting image, a base fitted on level and supporting the said display main body, a bracket capable rotating whose upper end is connected onto the display main body and its lower end is connected onto the base by using a hinge. It also comprises a rotating shaft which is fixedly connected on the base and used for connecting the lower end throughout the bracket and the base, multiple friction-force-producing components which are fixedly connected onto the rotating shaft and close fit the lower end of the bracket, and a friction-force-changing device for increasing the friction force between the bracket and the friction-force-producing component in a defined angle range while the bracket rotating, with the rotating shaft as center, relative to the base.

Description

technical field [0001] The invention relates to a display, in particular to a display hinge device used to connect a base and a support of the display and to make the support rotate. Background technique [0002] Under normal circumstances, if a flat-panel display such as a liquid crystal display (LCD) is to be placed on a table or used in other places, a stand capable of supporting the display must be provided. This support must be connected to the rear portion of the display with a hinge device as a medium, so that the user can adjust the inclination angle of the display to a suitable angle. [0003] In Korean Patent No. 2003-41767 (published on May 7, 2003), a display device using a 2-fold hinge structure in the bracket is disclosed for the first time to make the rotation angle adjustment of the display main body more free. [0004] Referring to FIG. 1 , the above-mentioned conventional display device will be briefly described. [0005] The support 3 for connecting the ...

Problems solved by technology

[0011] However, as mentioned above, when the angle of the bracket is to be adjusted, if the rotation angle of the bracket is larger, the elastic force of the torsion spring 6c will also increase accordingly.

Therefore, if the user removes the applied external force after applying an external force to turn the stand above a certain angle, the stand cannot maintain the previously adjusted angle due to the elastic force of the torsion spring, and will move slightly to the upper side in the opposite direction. , so there is a problem that the bracket cannot be adjusted to a suitable angle at one time

[0012] Especially when the bracket is to be completely folded relative to the base, since the reaction force of the torsion spring is very large, there will be a problem that it cannot be completely folded
