Input device for tablet computer
An input device for a tablet computer is provided. The input device includes a base and a touch switch member. The touch switch member includes a touch element and a power switch. The touch element is pivotally coupled with the base and exposed to a top surface of the base. When the tablet computer is placed on the base, the touch element is moved from an initial position to a triggered position through the tablet computer. Consequently, the power switch is pressed down and turned on.
1. An input device for a tablet computer, said input device being operated to input a command or information into said tablet computer via said input device, said input device comprising:
a base, wherein a keyboard and a placement region are disposed on a top surface of said base, and said placement region has a hollow portion; and
a touch switch member disposed on said base, and comprising:
a touch element pivotally coupled to said base, and comprising a touching part, an extension part and a pivotal part, wherein said touching part is exposed to said hollow portion, and said pivotal part comprises a first torsion spring, wherein said touch element further comprises a first compression spring, which is located at a first end of said touch element, wherein when said tablet computer is detached from said placement region, said touch element is returned to said initial position through said first compression spring and wherein said touch element further comprises a second compression spring, which is located at a second end of said touch element, wherein when said tablet computer is detached from said placement region, said touch element is returned to said initial position through said second compression spring; and
a power switch, wherein when said tablet computer is placed on said placement region, said touching part is moved from an initial position to a triggered position by said tablet computer, so said power switch is pressed down and turned on by said extension part.
2. The input device according to claim 1 wherein a wireless transmission module and a circuit board are further disposed within said base, wherein said power switch and said wireless transmission module are disposed on said circuit board, and said wireless transmission module is in communication with said keyboard and said tablet computer.
3. The input device according to claim 2 wherein said input device further comprises a main power switch and a power source, which are disposed on said base, wherein said main power switch is electrically connected with said power source and said circuit board.
4. The input device according to claim 2 wherein said wireless transmission module is a Bluetooth transmission module.
5. The input device according to claim 2 wherein when said power switch is first turned on, said wireless transmission module is enabled and operated in a search mode.
6. The input device according to claim 1 wherein a first end of said first torsion spring is sustained against said base, and a second end of said first torsion spring is sustained against said touch element, wherein when said tablet computer is detached from said placement region, said touch element is returned to said initial position through said first torsion spring.
7. The input device according to claim 1 further comprising a prop stand, which is disposed on said base for supporting said tablet computer.
8. The input device according to claim 1 wherein said placement region is a concave structure.
9. An input device for a tablet computer, said input device being operated to input a command or information into said tablet computer via said input device, said input device comprising:
a base, wherein a keyboard and a placement region are disposed on a top surface of said base, and said placement region has a hollow portion; and
a touch switch member disposed on said base, and comprising:
a touch element pivotally coupled to said base, and comprising a touching part, an extension part and a pivotal part, wherein said touching part is exposed to said hollow portion, and said pivotal part comprises a first torsion spring, wherein said pivotal part of said touch element further comprises a first shaft, a second shaft and a second torsion spring, and said base further comprises a first pivotal hole and a second pivotal hole, wherein said first shaft is penetrated through said first pivotal hole, said second shaft is penetrated through said second pivotal hole, said first torsion spring is sheathed around said first shaft, and said second torsion spring is sheathed around said second shaft; and
a power switch, wherein when said tablet computer is placed on said placement region, said touching part is moved from an initial position to a triggered position by said tablet computer, so said power switch is pressed down and turned on by said extension part.
10. The input device according to claim 9 wherein a first end of said second torsion spring is sustained against said base, and a second end of said second torsion spring is sustained against said touch element.
11. The input device according to claim 1 wherein a clamping element is further disposed within said base, and said pivotal part comprises a first shaft and said first torsion spring, wherein said first shaft is pivotally coupled to said clamping element, and said first torsion spring is sheathed around said first shaft.
