Mobile phone and key structure thereof

Abstract

The invention provides a mobile phone and a key structure thereof. The key structure is used for pressing a switch eccentrically arranged below the key structure. The key structure includes a pressing bearing stage, a pressing part which is connected with the first side of the pressing bearing stage and extends downwards to correspond to the switch, a fixing part which is arranged at the second side of the pressing bearing stage which is opposite to the first side; a pressing gap is left between the pressing part and the switch; the fixing part is connected with the pressing bearing stage through one elastic arm; the pressing part has a first state in which the pressing part contacts with the switch and a second state in which the pressing part is separated from the switch; and the elastic arm enables the pressing part to recover the second state from the first state. The key structure is used for pressing the eccentrically-arranged switch. The key structure has the advantages of simplicity, simple production process, reduced cost and enhanced applicability.

Description

Technical field [0001] The present invention relates to the technical field of keys, in particular to a mobile phone and a key structure thereof. Background technique [0002] A traditional key switch consists of two parts, namely a key and a switch element. The switch element is set on a circuit board and is electrically connected to the circuit board. The switch element is turned on by pressing the key up and down to realize the connection with the switch element. Application function corresponding to the device. In general, the force application part of the button corresponds to the center of the switch component. The industry standard is that the eccentricity of the force application part of the button and the center of the switch component cannot exceed 0.3mm. However, due to circuit structure and space constraints, in some cases , The eccentricity of the force application part of the button and the center of the switch components exceeds 0.3mm. If the traditional button st...

Problems solved by technology

Under normal circumstances, the force application part of the button corresponds to the center of the switch component. The industry standard is that the eccentricity of the force application part of the button and the center of the switch component cannot exceed 0.3mm. However, due to circuit structure and space constraints, in some cases , the eccentricity between the force part of the button and the center of the switch component exceeds 0.3mm. If the traditional button structure is continued, it will make the pressing feel poor and the button function will not be realized, and will even increase the complexity of the structural design and make the production process more efficient. difficulty
