Keyboard and terminal

Abstract

The invention discloses a keyboard and a terminal. The keyboard comprises a keyboard body and an input unit, wherein the keyboard body comprises a key slot with an upward opening; the input unit is installed in the key slot; the input unit comprises a capacitive sensor, an elastic member, an adjustment mechanism, a flexible circuit board and two touch sensors; the capacitive sensor is arranged inthe key slot; two electrodes of the capacitive sensor are alternately arranged in an up-down direction; the elastic member is located between the two electrodes of the capacitive sensor and is used for supporting the upper electrode of the capacitive sensor; the adjustment mechanism is arranged in the key slot and is used for adjusting a deformation height of the elastic member; one touch sensor is located on the upper electrode of the capacitive sensor; the other touch sensor is located on the outer end surface of the key slot; and the flexible circuit board is electrically connected with thetwo touch sensors. A touch plate is integrated on the keyboard to realize multifunction of the keyboard. The keyboard is capable of decreasing volumes of notebook computers when being applied on thenotebook computers.

Description

technical field [0001] This article relates to the field of terminal technology, especially a keyboard and a terminal. Background technique [0002] At present, keyboards are mainly divided into mechanical type, film type and non-contact electrostatic capacitance type. [0003] The mechanical keyboard is similar to a metal contact switch. The working principle is to make the contacts conduct or disconnect. It has the characteristics of simple process, high noise and easy maintenance. [0004] The interior of the membrane keyboard is divided into three layers, the upper layer is the positive circuit, the lower layer is the negative circuit, the middle is a non-conductive plastic sheet, and then the pressing module (usually including the keycap, the movable module under the keycap, and the rubber cap) is placed on the top. When the finger is pressed down from the keycap, the top (positive circuit) and the bottom (negative circuit) will be in contact with electricity or the di...

AI Technical Summary

Problems solved by technology

Its characteristics are that the wear rate is extremely small or even negligible, and there is no hidden danger of poor contact, and the noise is low, it is easy to control the feel, and it can produce high-quality keyboards, but the process is more complicated than mechanical keyboards.

[0006] Existing notebooks are equipped with a touchpad on the side of the keyboard, which is independent from the keyboard, which will increase the volume of the notebook
