Abstract
The present invention relates to a keyboard, including a first baseboard, a second baseboard, a deformation element, a key cap, and a connecting element. The deformation element is disposed between the first baseboard and the second baseboard and is capable of deforming according to a received voltage signal. The deformation element drags the second baseboard to move in a first direction when the deformation element receives the voltage signal and therefore deforms to be in an extended state, so that the key cap is at a first height. The deformation element pushes the second baseboard to move in a second direction when the deformation element does not receive the voltage signal and therefore deforms to be in a bent state, so that the key cap is at a relatively shorter second height.
Claims9
A keyboard, disposed in a notebook computer, wherein the keyboard comprises:
- a first baseboard;
- a second baseboard, disposed at one side of the first baseboard;
- a deformation element, disposed between the first baseboard and the second baseboard, separately connected to the first baseboard, the second baseboard, and a power supply circuit of the notebook computer, and configured to deform according to a voltage signal provided by the power supply circuit;
- a key cap, located above the first baseboard, the second baseboard, and the deformation element and capable of moving relative to the first baseboard and the second baseboard;
- and
- a connecting element, separately connected to the key cap, the first baseboard, and the second baseboard, wherein the deformation element drags the second baseboard to move in a first direction when the deformation element receives the voltage signal and therefore deforms to be in an extended state, so that the key cap is at a first height;
- and the deformation element pushes the second baseboard to move in a second direction when the deformation element does not receive the voltage signal and therefore deforms to be in a bent state, so that the key cap is at a second height that is shorter than the first height.
