Problems solved by technology

It overcomes the problem that the capacitive charge sensing method is sensitive to the change of conductance and dielectric parameters caused by the movement of external objects and is easy to cause misoperation. It also overcomes the low operation sensitivity of the ordinary piezoelectric sensing method and cannot completely prevent high impact interference the problem of misoperation

Embodiment 1

[0035] figure 1 A is a schematic diagram of the anti-vibration sensor touch switch structure and circuit connection, such as figure 1 As shown, the force-sensitive sensor is fixed on the back of the touch panel 2 with the joint 3, and the touch panel 2 is pressed with a finger 1, and the blocking wall structure 7 connects the touched force-sensitive sensor 4 with the adjacent force-sensitive sensor 5 , 6 are separated to prevent the spread of stress and deformation after a single key press and affect the adjacent force-sensitive sensor unit, figure 1 A only shows a one-dimensional structure, in fact, the switch can be set as a two-dimensional array structure. The sensor is connected with the circuit with the connection wire 8, and the connection wire can also be replaced by a flexible conductive spring or an elastic contact piece.

[0036] Capacitor 9, signal amplifier 10, and limiter 12 are optionally set in the circuit. Dotted line 11 is a path that bypasses optional compo...

Abstract

The invention discloses a shockproof type sensing touch switch and a control method. The switch comprises a touch panel, a force sensor and a connector. The force sensor is fixed to the back face of the touch panel through the connector, the touch panel is deformed after being subjected to touch pressing force and external disturbance acting force, deformation is transmitted to the force sensor through the connector, and the two kinds of deformation is converted into electric signals through the force sensor. An amplitude limiting integral circuit differs the touch signals from the disturbance signals according to the frequency spectrum features of the signals. According to the control method of the shockproof type sensing touch switch, the amplitude limiting integral circuit differs the touch signals from the disturbance signals, and therefore shockproof performance and impact and disturbance resistance of the switch are greatly improved, and meanwhile operating sensitivity is improved.

Description

technical field [0001] The invention relates to a method from the occurrence of an operator's touch action to the generation of a definite switch output signal and an anti-vibration sensory touch switch. Background technique [0002] Current touch (touch) switches mainly include micro-mechanical, capacitive charge sensing and single piezoelectric. [0003] The micro-mechanical switch structure has the characteristics of low cost, easy manufacture and steady-state pick-up function. However, due to the moving parts of the micro-mechanical structure, holes need to be opened on the hard panel, thus forming gaps, and its waterproof performance requires compensate in other ways. Micro-mechanical switches also suffer from mechanical wear, resulting in replacement after a certain number of operations. [0004] Since the capacitive charge sensing switch adopts a non-mechanical detection method, it avoids the problem of opening holes on the hard panel due to the moving parts of the ...
