Description
Technical field
The present invention relates to keyboard technical field, more particularly to a kind of vocal structure of keyboard switch.
Background technology
Keyboard is a kind of application and is installed on the switch on keyboard, and its primary structure includes shell, pressing piece, pressure
Bar, static contact, movable contact spring etc., it is mainly acted on power contact by the way that pressing piece is up and down so that movable contact spring and stationary contact
Piece contact is connected or separated realizes keypress function.Clear and melodious knock is sent during keyboard use to tend to give people to bring U.S.
Wonderful experience, existing sounding is mainly the activity from the metal clips in keyboard switch, by metal clips
Clashed into plastic cement and send sound, but metal clips is susceptible to the situation of oxidation, laying dust with use time increase, causes gold
Category shell fragment activity failure, sounding effect also fails therewith.
The content of the invention
The present invention in view of the existing deficiencies of the prior art, there is provided a kind of vocal structure of keyboard switch, its can make keyboard by
Key sounding is clear and melodious, and sounding is not influenceed by steam and dust, improves keyboard service life.
To achieve the above object, the present invention is using following technical scheme：
A kind of vocal structure of keyboard switch, including shell and the press component being movably installed in shell, the pressing
Component includes keycap and pressing lever, and the lower end of the keycap is provided with the storage tank that Open Side Down, and the side of the storage tank is provided with
Skewed slot inside and outside storage tank, the pressing lever upper end is provided with gag lever post corresponding with skewed slot, the pressing lever it is upper
End is movably installed in storage tank, and the gag lever post is stuck in skewed slot, and being provided with the storage tank makes pressing lever have all the time
There is the first return unit of the trend for extending downwardly from, the through hole extended downwardly from for pressing lever, the pressing lever are provided with the shell
Lower end side be provided with spacing block set, the both sides of the spacing block set are slot to make way, and the inside lower end of the through hole is provided with and limit
The corresponding block of position projection, the both sides of the block are resigning step.
Used as a kind of preferred scheme, first return unit is (the first back-moving spring, the upper end of the pressing lever be provided with
The mounting groove of (the first back-moving spring adaptation, is provided with the limited post for extending downwardly from the storage tank, during assembling, described first resets
Spring is placed on limited post outside, and lower end is butted in mounting groove.
Used as a kind of preferred scheme, the skewed slot is two, and described two skewed slots are respectively arranged on the relative both sides of storage tank,
And two skewed slots are provided with corresponding two with two skewed slot difference towards inclined in opposite directions, the both sides of the pressing lever upper end
Gag lever post.
As a kind of preferred scheme, the resigning groove depth of the length more than limited block both sides of the block.
As a kind of preferred scheme, the second reset of the trend for making press component that there is reset all the time is provided with the shell
Part, second return unit is second back-moving spring.
Used as a kind of preferred scheme, the shell includes upper casing and lower casing, and the both sides of the lower casing are provided with outwardly
Fixture block, the upper casing is provided with the draw-in groove being adapted to fixture block, and the upper casing is stuck in draw-in groove by fixture block with lower casing and snapped connection.
Used as a kind of preferred scheme, on lower casing, the second back-moving spring is in through hole for foregoing through hole.
Operation principle of the present invention is as follows：
When not having external force to act on, pressing lever is located at the bottom of skewed slot in the presence of (the first back-moving spring, and presses
The lower surface of the spacing block set of bar lower end is butted on the upper surface of the block on the inside of through hole, is under external force, and pressing lever is to oblique
Groove upper end is moved, and is rotated in the presence of inclined-plane, and after certain altitude is risen to, spacing block set and block just mutually stagger,
Pressing lever is extended downwardly from rapidly in the presence of (the first back-moving spring, and block is struck in the slot to make way of spacing block set side, from
And send clear and melodious knock.
The present invention has clear advantage and beneficial effect compared with prior art, specifically, by keycap lower end
Storage tank is set, and skewed slot is set in storage tank side, pressing lever is rotated under skewed slot effect in pressing, so that pressing
Bar clashes under (the first back-moving spring effect with the block in through hole, realizes keyboard and sends sound automatically in pressing,
Compared to traditional vocal structure, this kind of structure is less prone to the situation of keyboard switch component wear, in (the first back-moving spring
Elastic force effect is lower can for a long time to keep clear and melodious knock；Due to storage tank, Open Side Down, and skewed slot is arranged on storage tank
Side, in use dust, steam be not easily accessible inside keycap, the part of keyboard switch is not susceptible to obstruction, oxygen
The phenomenon of change, can keep the working condition of stabilization, and service life is more longlasting, up to more than 100,000,000 times, while sound does not receive dust
Deng foreign object influence, in the absence of oxidative phenomena.
It is the specific purposes and function that more clearly illustrate architectural feature of the invention, technological means and its reached, under
