Abstract

Disclosed is a hinge mechanism for the tilting angle of a flat display panel to change flexibly within the range from 0 to 135 degrees. Therefore, this mechanism enables the flat display panel to tilt smoothly and to stop statically at any position within the range. It is widely applicable to notebook PCs.

Flexible Hinge Mechanism

       Disclosed is a hinge mechanism for the tilting angle of a
flat display panel to change flexibly within the range from 0 to 135
degrees. Therefore, this mechanism enables the flat display panel to
tilt smoothly and to stop statically at any position within the
range.  It is widely applicable to notebook PCs.

      As shown in Fig. 1, this mechanism consists of a shaft,
bracket, FFG (Flexible Friction force Guide) with three dimensional
surface, collar with spherical surface, coil spring and screw.

      Fig. 2 shows the relation between the spring tension and the
tilting angle within the range from 0 to 135 degrees.  It is possible
to change the spring tension by reforming the FFG and/or by selecting
the spring structure. But, in the current technology, it is
impossible to change this holding force, so that the spring tension
is overloaded at around 90 degrees (see the CURRENT line in Fig. 2).
The tilt angle can be changed smoothly and easily by reducing this
overloading.

      Fig. 3 shows the movement of this mechanism from 0 to 135
degrees.
