Abstract

The invention belongs to the technical field of keys, especially relates to a pressure induction key structure and a terminal device having the same, for solving the technical problems of relatively large space occupation, proneness to water inflow, relatively weak overall structural strength, relatively poor reliability and proneness to wrong touch of mechanical keys in the existing terminal devices. According to the pressure induction key structure provided by the invention, pressure measurement is realized by a simply supported beam type pressure induction component. When a user applies a pressure to a pressing area, the pressure is transferred onto a first fulcrum by a structural frame of the terminal device, and then the pressure is transferred onto an elastic bearing plate. Meanwhile, since a strutting piece is fixed to the structural frame of the terminal device, a reactive force of a force applied by the user acts on a second fulcrum, and the pressure is entirely concentrated on the elastic bearing plate. The elastic bearing plate generates deformation under the action of the pressure. A pressure sensor detects the deformation of the elastic bearing plate, the pressure sensor outputs a pressure signal to a pressure induction detection circuit, and the pressure signal is output to a processor after being analyzed and processed for carrying out an action.

Description

technical field [0001] The invention belongs to the field of button technology, and in particular relates to a pressure-sensitive button structure and a terminal device with the pressure-sensitive button structure. Background technique [0002] Terminal devices in the prior art, such as mobile phones and tablet computers, all use mechanical buttons to switch the terminal device on and off, adjust the volume, and the like. see figure 1 , because the mechanical key needs a certain stroke to be effective, so it is necessary to open a mounting hole 2011 for accommodating the mechanical key cap 202 on the structural frame 201 of the terminal device. When the user presses the mechanical key cap 202, the mechanical key stroke control sheet 203 is compressed inwardly until a certain stroke is reached, and then the mechanical key circuit 204 can be activated to enable the system to recognize the key information. The existing mechanical buttons are not conducive to the structural de...
