Power control apparatus for hinge device

A power control apparatus for coupling a first unit to a second unit, the power control apparatus comprising:

• a hinge device comprising a first portion secured to the first unit and a second portion secured to the second unit and pivotally engaged with the first portion, the first portion including a sleeve, the second portion including a bearing seat and a loading board attached to the bearing seat, the bearing seat including a base, a neck portion, and a shaft, the neck portion extending upwardly from the base, the shaft extending from an end of the neck portion and being pivotally received in the sleeve;
• a suspend switch being attached to the loading board, the suspend switch having an elastic button provided on the second portion;
• and
• an actuator provided on the first portion and extending from the sleeve;
• wherein the first portion can rotate relative to the second portion between a first position in which the button protrudes out from the switch, and a second position in which the button is depressed into the switch by the actuator so that the second unit terminates signals and power delivery to the first unit.

A power control apparatus assembly comprising:

• a first unit providing power,
• a second unit receiving the power to show images;
• a hinged device including a sleeve section secured to one of the first unit and the second unit, and a shaft section secured to the other of the first unit and the second unit under a condition that said sleeve section coaxially rotatably surrounds said shaft section;
• an actuation switch mounted to said other of the first unit and the second unit, at least part of the actuation switch being configured for being laterally/radially moveable relative to said other of the first unit and the second unit and said shaft section;
• an actuator coaxially extending from a distal end of said sleeve section with a distance wherein said actuator is not of a full circumference but in a limited angle range corresponding to said actuation switch;
• wherein
• by means of rotation of the sleeve section about the shaft section, the actuation switch can be activated or deactivated by said actuator so as to decide whether the second unit receives the power or not.

A power control apparatus for coupling a first unit to a second unit, the power control apparatus comprising:

• a first unit providing power;
• a second unit receiving power to show images;
• a hinge device comprising:
• a first part secured to the first unit, the first part including a base, a connecting portion extending upwardly from the base, a shaft extending away from an end of the connecting portion, and a button being moveably installed in the base;
• and
• a second part secured to the second unit and pivotally engaged with the first part, the second part including a rotating portion configured for pivotally receiving the shaft and an extending portion extending laterally away from an end of the rotating portion and partially surrounding the shaft, the extending portion having an actuator segment corresponding to the button, the actuator segment having an open-end radial cross section;
• wherein the first part can rotate relative to the second part between a first position in which the actuator segment is away from the button and the button is deactivated, and a second position in which the actuator segment touches and acts on the button so that the button is activated and the second unit terminates signals and power delivery from the first unit.
