Problems solved by technology

However, some force sensors, such as piezoelectric force sensors, require direct contact between the upper and lower surfaces of the device components during the force detection process, and long-term direct contact or extrusion will affect the touch module and display module in the touch screen. For example, when the piezoelectric force sensor is installed between the display module and the installation frame, long-term direct contact or extrusion between the piezoelectric force sensor and the display module will cause abnormal display of the display module, resulting in touch screen unable to work properly

Abstract

The present invention discloses a pressure-sensitive touch device and a terminal device with the same. The pressure-sensitive touch device comprises a mounting frame, a touch screen, and a sensor assembly. The touch screen is arranged above the mounting frame, the sensor assembly is arranged between the mounting frame and the touch screen, and the sensor assembly comprises a support piece arrangedon the bottom of the touch screen and a sensor arranged on the bottom of the support piece. According to the pressure-sensitive touch device disclosed by the present invention, the support piece is arranged between the touch screen and the mounting frame, and the sensor is arranged between the support piece and the mounting frame, so that on one hand, the sensor can be prevented from directly contacting the touch screen, and on the other hand, the force at a certain point can be evenly dispersed by the support piece to improve the problem of touch screen stress concentration, to ensure the normal operation of the touch screen, and to improve the service life of the pressure-sensitive touch device.

Description

technical field [0001] The present invention relates to the technical field of communication equipment, in particular to a pressure-sensitive touch device and a terminal device having the same. Background technique [0002] Due to its advantages of ease of operation and flexibility, the touch screen has become the main means of human-computer interaction for personal mobile communication devices and comprehensive information terminals, such as mobile phones, tablet computers and super notebook computers. Among touch screens, capacitive touch screens are gradually being widely used in smart terminals due to their advantages of low cost, simple structure, and good durability. However, the capacitive touch screen in the related art can only sense the touch position and operation on the plane where the touch screen is located, and it is difficult to sense the touch parameters brought about by the change of the pressure vertically applied to the surface of the touch screen.
