Abstract

A portable display device is applicable to an electronic device having a socket provided with a second electrical connector. The portable display device includes a body having a display and a plurality of operating keys; an extension portion having a first end pivotably connected to the body, and a second end pluggable into the socket; a first electrical connector installed on the second end of the extension portion and engageable with the second electrical connector; and a lock member installed on the extension portion for locking the extension portion in the socket.

Claims

1. A portable display device applicable to an electronic device having a socket provided with a second electrical connector, the portable display device comprising:

a body having a display and a plurality of operating keys;

an extension portion having a first end pivotably connected to the body, and a second end pluggable into the socket;

a first electrical connector installed on the second end of the extension portion and engageable with the second electrical connector; and

a lock member installed on the extension portion for locking the extension portion in the socket, wherein the lock member comprises a lock hook disposed on the first end of the lock member, a pressing portion movable in accordance with a movement of the lock hook, and an electrical switch penetrating the pressing portion.

2. The portable display device of claim 1, wherein the electronic device further comprises a lock hole disposed in the socket of the electronic device, and the extension portion can be locked in the socket of the electronic device by engaging the lock hook of the lock member with the lock hole of the socket.

3. The portable display device of claim 2, wherein the lock hook is released from the lock hole by pressing the lock member through the pressing portion, thus the extension portion can be taken out from the socket of the electronic device so that the first electrical connector can be disconnected from the second electrical connector.

4. The portable display device of claim 3 wherein the electrical switch is operated for interrupting a software program stored in the body, and further disconnecting the first electrical connector from the second electrical connector while pressing the pressing portion, so as to avoid adversely affecting a main program running in the electronic device.

5. The portable display device of claim 1 further comprising a pivoting mechanism pivotably connected to the body and fixed to the first end of the extension portion.

6. The portable display device of claim 5, wherein the pivoting mechanism has a first pivoting member longitudinally pivotably connected to the body, and a second pivoting member laterally pivotably connected to the first pivoting member and fixed to the first end of the extension portion.

7. The portable display device of claim 5, wherein the pivoting mechanism has a first pivoting member pivotably connected to the body and having a socket joint, and a third pivoting member fixed to the first end of the extension portion and having a ball joint jointed to the socket joint.
