Problems solved by technology

[0006] Through the analysis of the above two waterproof schemes, it can be seen that although the splash waterproof scheme can be waterproof, it cannot be dustproof, and it is also necessary to carry out a waterproof design for the substrate and the shell of the keyboard, especially to ensure the diversion The seal between the sleeve and the small hole on the substrate and the diversion hole on the shell, so the design of the waterproof structure is more complicated
The immersion waterproof solution needs to seal the film circuit with silica gel, so the manufacturing process is more complicated and the manufacturing cost is increased.
[0007] In view of this, it is urgent to optimize the design of the existing keyboard waterproof measures to solve the problems of complex structure, complicated manufacturing process and high manufacturing cost of the keyboard waterproof and dustproof scheme.

Embodiment Construction

[0028] The core of the present invention is to provide a keyboard, in which a thin keyboard membrane made of silica gel is mounted on the keycap and squeezed on the keyboard frame from top to bottom through the keyboard frame. In this way, the thin-film circuit is completely separated, so that the complete waterproof and dustproof function of the keyboard is realized without affecting the function and feel of the keyboard, eliminating the possibility of water entering the keyboard, and ensuring the use of the keyboard to the greatest extent. Safety. The specific implementation manner will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can better understand.

[0029] See figure 1 and figure 2 ,in, figure 1 It is a schematic diagram of the exploded structure of the keyboard described in the specific embodiment, figure 2 It is a cross-sectional view of the keyboard described in the specific embodiment.

Abstract

The present invention discloses a keyboard which comprises a housing and the following components in the housing: a thin-film circuit, a keyboard frame, a keyboard film and a keyboard base board. The keyboard base board is provided with a plurality of key caps which are adapted with contacts on the thin-film circuit. The keyboard film is provided with inner concave accommodating parts which are respectively adapted with each key cap. The keyboard frame is mounted on the housing through clamping mounting. The keyboard frame is buckled on the key caps and furthermore the keyboard film is pressed to abut against the keyboard base board through the keyboard frame from top to bottom. According to the keyboard of the invention, the keyboard film is buckled on the key caps and furthermore is pressed to abut against the keyboard base board through the keyboard frame from top to bottom. On condition that the keyboard function and the hand feeling do not reduce, a totally waterproof and dustproof function is realized. Furthermore falling-off of the key cap can be prevented thereby ensuring high use safety of the keyboard and obtaining better appearance effect.

Description

technical field [0001] The invention relates to a keyboard, in particular to a waterproof and dustproof keyboard. Background technique [0002] The keyboard is one of the most commonly used input devices for electronic equipment, and it is widely used in computers, electronic instruments and various terminal equipment. [0003] In order to avoid accidents during the use of the keyboard, existing keyboards generally have waterproof measures. There are two kinds of waterproof measures: one is splash waterproof, and the other is immersion waterproof. [0004] The scheme adopted for the splash-type waterproof is: a plurality of diversion holes are provided on the bottom surface of the keyboard shell, and at the same time, a plurality of small holes are correspondingly arranged on the substrate below the keys of the keyboard, and these small holes are arranged through the diversion sleeve. The hole is connected with the diversion hole on the lower shell of the keyboard. Since t...
