A waterproof sensor keyboard

Abstract

A waterproof inductive keyboard, the keyboard includes a substrate, the substrate is dug with a number of grooves, the grooves are used to install the rebound mechanism connected to the keycap, the groove is formed on the substrate with a thinner area, the In the region, after the keycap is pressed, the pressure is transmitted to the region through the rebound mechanism to form a substrate deformation region. A strain sensor is arranged on the back of the substrate close to the substrate deformation region, and the strain sensor is used to detect the deformation of the substrate deformation region. Each substrate deformation area on the back of the substrate is provided with a transverse axis strain sensor and a longitudinal axis strain sensor, each transverse axis strain sensor is connected in series, and each longitudinal axis strain sensor is connected in series to form a strain sensor array on the back of the substrate , the array has a channel in the direction of the horizontal axis and a channel in the direction of the vertical axis, and by simultaneously collecting the strain signals of the channel in the direction of the horizontal axis and the channel in the direction of the vertical axis, the coordinates of the pressed button and the pressure of the button are obtained.

Description

technical field [0001] The invention belongs to the technical field of computer equipment, and particularly relates to a waterproof induction keyboard. Background technique [0002] Among the existing keyboard types, one type of keyboard structure is a key-flicking and conducting circuit structure, and this type of keyboard cannot achieve the waterproof function. Another type of keyboard, such as capacitive sensing key keyboard or membrane switch key keyboard, although it can be waterproof, the capacitive screen keys have no tactile feeling, no feel, or the pressing experience of the keys is poor, and there is water or conductivity on the surface of the keys When the material is used, the function will be wrong, and the capacitive button can only be pressed by a conductive object, and it is easy to fail when wearing thick gloves. Also, existing keyboards cannot detect key pressure. SUMMARY OF THE INVENTION [0003] The invention provides a waterproof sensor keyboard, whi...

Problems solved by technology

[0002] Among the existing types of keyboards, one type of keyboard structure is a key-press and conduction circuit structure. This type of keyboard cannot achieve waterproof function.

And another type of keyboard, such as capacitive sensing key keyboard or membrane switch key keyboard, although it can be waterproof, but the capacitive screen key has no touch, no hand feeling, or the pressing experience of the key is very poor, and there is water or conductive on the surface of the key. The function will go wrong when the material is used, and the capacitive button can only be pressed when it is a conductive object, and it is easy to fail when wearing thicker gloves

In addition, existing keyboards cannot detect key pressure
