Keyboards and Portable Electronic Devices

Abstract

The invention relates to a keyboard and a portable electronic device. The keyboard comprises a bottom plate, keys and an elevating plate, wherein projecting bent arms are formed on the bottom plate; the projecting bent arms are provided with through holes; the keys are arranged on the bottom plate, and comprise key caps and actuating parts; the key caps can move up and down between folding positions and releasing positions relative to the bottom plate; the actuating parts are provided with bent arm portions and bearing arm portions; the bent arm portions can movably penetrate through the through holes in order that the bearing arm portions can swing up and down relative to the through holes; and when the key caps are positioned at the releasing positions, the bearing arm portions are used for supporting the key caps. The elevating plate is arranged below the bottom plate in a way of moving relative to the bottom plate, and is provided with support posts; the support posts movably penetrate through the bottom plate to be pressed against the bent arm portions of the actuating parts; and when the elevating plate and the bottom plate get close to each other to drive the bent arm portions to swing upwards relative to the through holes through the support posts, the bearing arm portions swing downwards relative to the through holes in order that the key caps move downwards to the folding positions.

Description

technical field [0001] The invention relates to a keyboard and a portable electronic device, in particular to a keyboard using a support column of a lifting plate to push an actuating member to fold a keycap and a portable electronic device including the keyboard. Background technique [0002] As far as the current usage habits of notebook computers are concerned, the keyboard is one of the indispensable input devices for inputting characters, symbols or numbers. Recently, due to the thinning trend of notebook computers, there is also a demand for thinner keyboards used in notebook computers. [0003] The conventional key is often provided with an elastic element, such as a rubber dome, etc., to serve as a source of elastic force for the keycap to reset when the key is used. However, the known elastic element has a specific height, so when the top cover and the bottom casing of the notebook computer are folded, in order to prevent the keycaps on the bottom casing from damag...

AI Technical Summary

Problems solved by technology

However, the known elastic element has a specific height, so when the top cover and the bottom casing of the notebook computer are folded, in order to prevent the keycaps arranged on the bottom casing from damaging the display screen arranged on the top cover, the upper There is often a gap between the cover and the lower case to accommodate the keycaps, which will limit the design of the notebook computer's appearance and size, and is not conducive to the thinning trend of the notebook computer
