Abstract

The invention relates to an elastic arm key-press structure which is used for an electronic device provided with a trigger unit and is used for pressing the trigger unit to input control signals. The elastic arm key-press structure comprises a pressing part, a plurality of positioning parts, a plurality of elastic connecting parts and a plurality of reinforcing parts. The pressing part is arranged correspondingly to the trigger unit and is used for moving along a pressing direction to trigger the trigger unit; the positioning part is arranged on the outer edge of the pressing part to limit the pressing part to move only along the pressing direction. The elastic connecting part is connected with two sides of the pressing part to form the elastic arm structure then balance returning elasticity is supplied after the outer pressure which acts on the pressing part is released. The plurality of reinforcing parts are arranged between at least two elastic connecting parts to reinforce the rigidity of the elastic connecting part so as to solve the press-key swaying in the operation of the prior art.

Description

technical field [0001] The invention relates to an elastic arm key structure, in particular to an elastic arm key structure applied to an electronic device with a touch control unit. Background technique [0002] The functions of current electronic devices such as notebook computers, mobile phones, personal digital assistants (Personal Digital Assistant; PDA) and digital cameras that are commonly used by people continue to increase, and the function selection of these electronic devices must be set through the control panel of the electronic device. On the key to complete, so will cause the number of keys to increase. In order to comply with the development trend of portable electronic devices, it is impossible to increase the number of buttons, and the above-mentioned situation can only be satisfied by using buttons with multiple functions. Therefore, the ingeniously designed, small footprint and powerful four-way key came into being, and has become a standard configuratio...
