Problems solved by technology

[0004] However, most of the shrapnel components need to be installed on the keys with engaging parts such as hooks, which easily makes the structure of the key components complex, which is not conducive to the current trend of miniaturization of portable electronic devices.
However, due to the limitation of the structure, the shrapnel made of plastic material cannot achieve the best elasticity, and may not be able to provide enough elastic force to drive the pressed button to return to its original position in time, resulting in inconvenient operation.

Abstract

The invention relates to a button structure which is used for pressing a switch arranged on an electric device. The button structure comprises a button slidingly arranged on the electric device and two opposite Archimedes-spiral-shaped elastic arms. The button comprises a button body which extends to form the elastic arms, the elastic arms can be clamped onto the electric device, the elastic arms deform to drive the button to slide relative to a shell when the button is pressed, and accordingly a pressing block is driven to press the switch. The invention further relates to the portable electric device applying the button structure.

Description

technical field [0001] The invention relates to a key structure and a portable electronic device using the key structure. Background technique [0002] With portable electronic devices such as mobile phones, in addition to the existing input devices such as keyboards and touch panels, many portable electronic devices are also provided with function keys on their side walls, which can be used to control the power switch, volume control, etc. of the portable electronic devices. Camera focal length adjustment, camera switch and other functions for quick operation. [0003] Most of the existing button assemblies are equipped with a button and a shrapnel assembly, and the shrapnel assembly is installed on one side of the button. When the button is pressed, the button will trigger the switch in the portable electronic device to establish a corresponding functional circuit with the circuit board, and at the same time, the elastic component will be elastically deformed; after the b...
