Keyboard module and electronic device having the same

摘要

A keyboard module adapted to be used in an electronic device. The electronic device has a casing. The casing has a containing opening. The keyboard module contained in the containing opening includes a bottom plate, an elastic component, a cover and a key cap disposed on the elastic component. The bottom plate disposed within the casing has a circuit. The elastic component is disposed on the bottom plate or the circuit. The cover movably disposed in the containing opening is located above the bottom plate. The cover has an opening aligned to the elastic component. A portion of the key cap protrudes from the opening. Another portion of the key cap interferes with the opening, such that the key cap resists elasticity of the elastic component and moves to shorten a distance between the key cap and the bottom plate when the cover moves toward the bottom plate.

主权项

1. A keyboard module adapted to be used in an electronic device, the electronic device having a casing, the casing having a containing opening, the keyboard module contained in the containing opening and comprising:
a bottom plate disposed within the casing, and having a circuit disposed thereon or therebeneath; at least one elastic component disposed on the bottom plate or the circuit; a cover disposed movably up-and-down in the containing opening with respect to the casing and located above the bottom plate, wherein the cover has at least one opening respectively aligned to the elastic component; and at least one key cap respectively disposed on the corresponding elastic component, wherein at least a portion of the key cap protrudes from the corresponding opening so as to be pushed by a user, and at least another portion of the key cap interferes with the corresponding opening so as to drive the key cap to resist elasticity of the elastic component and move to shorten a distance between the key cap and the bottom plate when the cover moves downward to the bottom plate, wherein the cover is reset via elastic force of the elastic component.
