Electronic device

Abstract

The invention discloses electronic equipment. The electronic equipment comprises a shell, a screen and a pressure sensing module; the screen is covered on the shell, and the pressure sensing module is arranged in the shell; the pressure sensing module comprises a movable block and a fixed block, and the movable block and the fixed block form a capacitor; the movable block comprises a pressing part and a first bearing part arranged on the pressing part, and a plurality of parallel first rib plates are arranged on the first bearing part; a second bearing part is arranged on the fixed block, a plurality of parallel second rib plates are arranged on the second bearing part, each first rib plate and each second rib plate are arranged at intervals in a mutual insertion mode, and a parallel plate capacitor is formed between the adjacent first rib plate and second rib plate; and the pressing part is attached to the screen, and the fixed block is fixed in the shell.

Description

technical field [0001] The application belongs to the technical field of pressure sensing, and in particular relates to an electronic device. Background technique [0002] With the rapid development of electronic equipment, the advantages of hidden buttons have become increasingly prominent. In the prior art, a resistive chip-type pressure-sensitive module is generally installed on the side of an electronic product to realize the function of a hidden button. The piezoresistive sheet is pasted with long-side tangential piezoresistors and radial piezoresistors inside. When a pressing force acts on the piezoresistive sheet, the tangential and radial stretching directions are completely opposite each time, and the deformation obtained each time The direction is also opposite, so the pressure can be obtained through the corresponding changes of the Wheatstone full-bridge detectors.

Problems solved by technology

[0003]With the increasing demand for screen functions in the interaction of electronic devices, the idea of ​​combining pressure-sensitive buttons and screens emerged as the times require, but the current resistive pressure-sensitive modules , because each time the pressure must be applied directly above the device to generate pressure sensing, so if this resistive pressure-sensitive module is used in screen interaction, since it cannot be directly attached to the screen, it needs to be reserved around the screen. Open the space for placing the resistive pressure-sensitive module, and then pass the external force to the pressure-sensitive module through the screen cover that is directly above the screen and the resistive pressure-sensitive module. This setting method will cause resistors to be placed around the screen. The position of the type pressure-sensitive module forms a black frame because there is no display screen (such as Figure 1), affecting user experience
