Hinge assembly for notebook computers
The present invention discloses a hinge assembly for notebook computers capable of keeping a screen of a monitor connected face-to-face with a main system of the notebook, and such hinge assembly also can keep an included angle between the monitor and the main system from zero degree (i.e. closed status for stacking the monitor and the main system) to 180 degrees (i.e. horizontally aligned status of the monitor and the main system). Furthermore, the monitor can continue to be turned over until the screen of the monitor faces the back of the main system, and then further till the monitor and the main system are in the back-to-back contact with each other.
1. A hinge assembly for a notebook computer comprising:
a) a monitor having a screen;
b) a main system;
c) a connecting body located between the monitor and the main system;
d) at least one upper pivot pivotally connecting two ends of a first side of the connecting body to two ends of the monitor;
e) at least one lower pivot pivotally connecting two ends of a second side of the connecting body to two ends of the first end of the main system, the monitor being movable between open and closed monitor positions;
f) a hidden keyboard pivotally connected to a second end of the main system and movable between open and closed keyboard positions, the hidden keyboard having a press key surface; and
g) at least one communication cable including a first communication cable spirally coiled around each of the at least one upper pivot and the at least one lower pivot, and connected at a first cable end to the monitor and at a second cable end to the main system.
2. The hinge assembly according to claim 1 , wherein the main system has an accommodating groove, when the hidden keyboard is in the closed keyboard position, the hidden keyboard is located in the accommodating groove with the press key surface located adjacent to the main system.
3. The hinge assembly according to claim 1 , wherein the keyboard pivots more than 180 degrees between the closed and the open positions.
4. The hinge assembly according to claim 1 , further comprising two pivot members, the hidden keyboard is pivotally connected to the second end of the main system at each of two ends by one of the two pivot members, when the hidden keyboard is in the closed keyboard position, the hidden keyboard is located in the accommodating groove with the press key surface located adjacent to the main system.
5. The hinge assembly according to claim 1 , wherein at least one communication cable includes a second communication cable connecting the hidden keyboard and the main system.
6. The hinge assembly according to claim 1 , wherein each of the at least one communication cable is a soft parallel cable that is soft and bendable.
7. The hinge assembly according to claim 1 , wherein each of the at lest one communication cable has a thin film of Mylar.
8. The hinge assembly according to claim 1 , wherein, in the closed monitor position, the screen of the monitor is located adjacent to a top of the main system, and, in the open monitor position, a surface of the monitor opposite the screen is located adjacent to a bottom of the main system.
