Abstract

The invention relates to a keyboard which comprises a plastic cement bottom plate, a plural of buttons and a capacity touch control sensing piece. The plural of the buttons are arranged on the plastic bottom plate, and each button consists of a key cap and a support device. The support device is connected between the key cap and the plastic cement bottom plate and used for enabling the press cap to move between a pressing position and a non-pressing position, opposite to the plastic cement bottom plate. The plastic cement bottom plate is arranged below the plastic cement bottom plate and used for providing a touch operating signal to a computer device. The keyboard can reduce manufacture cost of the keyboard, and further improves touch sensing sensitivity of the keyboard.

Description

technical field [0001] The present invention relates to a keyboard, in particular to a keyboard in which a capacitive touch sensing sheet is arranged under a plastic bottom plate. Background technique [0002] With the development of touch sensing technology, there has been a design of integrating a capacitive touch sensing chip into a keyboard so that the keyboard can have a key control function and a touch sensing function, thereby improving the convenience of the keyboard in operation. In the prior art, the common configuration is to break the capacitive touch sensing sheet through the corresponding assembly hole and directly arrange it under the keycap. However, this design usually results in a time-consuming and labor-intensive assembly process, and the assembly holes without touch sensing capability will affect the sensing sensitivity of the capacitive touch sensing chip. Contents of the invention [0003] One of the objectives of the present invention is to provide...
