Abstract

Disclosed is a switching mechanism that may be utilized in a notebook personal computer provided with a Liquid Crystal Display (LCD) panel. When an operator closes the LCD panel, a boss on the surface pushes an actuator and a switch that are provided on the main logic board within a keyboard unit. As soon as the system detects that the LCD panel is closed via the actuator, the power saving function deactivates the backlight and the relating circuitry. The subject actuator has a unique elastic shape. The shape of actuator is effective to relieve the stress and also reliable to set the switch on.

Lid Close Actuator

      Disclosed is a switching mechanism that may be utilized in a
notebook personal computer provided with a Liquid Crystal Display
(LCD) panel.  When an operator closes the LCD panel, a boss on the
surface pushes an actuator and a switch that are provided on the main
logic board within a keyboard unit.  As soon as the system detects
that the LCD panel is closed via the actuator, the power saving
function deactivates the backlight and the relating circuitry.  The
subject actuator has a unique elastic shape.  The shape of actuator
is effective to relieve the stress and also reliable to set the
switch on.

      Fig. 1 shows the subject characteristic actuator.  A hole (1)
is provided on the main structure.  As shown in Fig. 2, the actuator
(3) and the switch (4) is provided under the hole (1).  When the LCD
panel is closed, the boss (2) on the surface of the bezel pushes the
actuator (3).  The stress of deformed actuator conducts the force to
set the switch (4) on.  The actuator can avoid a problem of
over-stress or short pushing force with its shape and behavior.
