Thin keyboard

Abstract

The invention discloses a thin keyboard, comprising a bottom plate assembly, a plurality of keys and a thin switch, wherein the bottom plate assembly comprises a circuit board and a support plate; the keys are arranged on the bottom plate, each key is provided with a key cap and a scissor pin above the key cap in sequence from top to bottom, the upper part of the scissor pin is in contact connection with the key cap, and the lower part of the scissor pin is connected with the support plate; the thin switch is connected with the circuit board, and comprises a surface cover, a press part, a base, a sounding piece and a contact spring, wherein the surface cover is provided with a press hole in the center; the press part is mounted in the press hole of the surface cover; the base is connected with the surface cover by riveting, the base is provided with a contact spring accommodating groove in the center, and the circumference of the contact spring accommodating groove is a base groove wall; the sounding piece is located on the base groove wall; the contact spring is horizontally arranged in the contact spring accommodating groove, the top of the contact spring is lower than the upper surface of the base, and the conducting part of the contact spring is located on the side of the base. The thin keyboard has the advantages of simple structure, low thickness, good user experience and the like.

Description

technical field [0001] The invention relates to a keyboard, in particular to a thin keyboard. Background technique [0002] The keyboard is a kind of computer peripheral equipment. The keyboard has a plurality of keys, and signals or instructions are input and transmitted to the computer by pressing the plurality of keys. Existing thin mechanical keyboards, such as the Chinese patent application titled "thin mechanical keyboard for laptop computers" with application number 2015100926090, disclose a thin mechanical keyboard for laptop computers, including circuit boards, scissor feet, keycaps, bases, and buttons. Zhi switch, spring, shell, etc., the circuit board is equipped with a reinforced iron plate, the reinforced iron plate has a hollow groove and a plurality of clamping parts at the corners, and a plurality of clamping parts are arranged on the scissors feet. The first positioning part and the second positioning part, the first positioning part is movably clamped on t...

AI Technical Summary

Problems solved by technology

The thin mechanical keyboard for laptop computers connects the keycap and the reinforced iron plate respectively through the scissors feet, and keeps the balance of the keycaps by the scissors feet in the process of pressing down the keycaps, and realizes the strike through the sound parts and contact shrapnels vertically arranged in the base. The sound of the sound and the conduction of the line, the vertically arranged sound parts and the contact shrapnel are placed in the base with the push button, which has the following disadvantages: 1. Due to the large thickness of the push button and the vertical arrangement of the contact shrapnel, its It is difficult to reduce the thickness, and the thickness of the base makes the overall thickness of the whole switch larger, which does not conform to the current trend of thinning; 2. The sound part of this key switch is set on one side of the base. When the user applies pressure, The force is uneven during the pressing down process, which is easy to damage the parts, and then affects the service life of the key switch; 3. The contact is located at the lower part of the contact piece, and the response is slow and the sensitivity is poor during the pressing down process.
