Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-9, a specific embodiment be an X gimbal silica gel button, including fallboard 1 and key chassis 2 to and set up the gimbal that constitutes by mutual articulated public frame 3 and female frame 4 between fallboard 1 and key chassis 2, still be provided with elastic silica gel spare 5 between fallboard 1 and the key chassis 2, be connected with the film switch below elastic silica gel spare 5, have the function of triggering the signal of telecommunication, still include a sound production piece 6 of pin joint on public frame 3, public frame 3 stretches out a wedge briquetting 31 along sound production piece activity direction, be provided with spacing step 41 on the female frame 4, wedge briquetting 31 extrudes piece 6 when pressing fallboard 1, sound production piece 6 holds power under the effect of wedge briquetting 31, then sound production piece 6 crosses the critical position of spacing step 41 of female frame and hits spacing step sound production.

The application is the preferred torsional spring 61 of sound producing component 6, the pin joint is on public protruding axle 32 on 3, torsional spring one end is fixed on public frame 3, and the torsional spring other end can hold power down and hit the spacing step 41 of hitting female frame and make a sound under wedge briquetting 31 effect, and this kind of fixed mode of beating is simple and convenient, and simple to operate can send the sound of beating when producing the key segment sense of falling, promotes user experience.

Because the torsional spring is metal bullet spare, and spacing step is the plastics material, can cause wearing and tearing when beating spacing step for a long time, can influence the life of button, and is further preferred, sound production piece 6 includes torsional spring 61 and pendulum 62, torsional spring 61 middle part and pendulum 62 middle part all pin joint are on public protruding axle 32 on putting up, the end of pendulum 62 is equipped with strikes piece 621, and the pendulum is plastic construction, torsional spring 61 one end is fixed, the piece 61 contact of striking on torsional spring 61 other end and the pendulum 62, torsional spring 61 holds power when pressing the button, and torsional spring 61 releases drive pendulum 62 lateral shifting when loosening the button, strikes the spacing step 41 that piece 621 hit the mother's frame and sound. This scheme has increased pendulum 62, and pendulum 62 and torsional spring 61 linkage, the piece that strikes on the torsional spring drive pendulum beats spacing step and makes a sound, has cushioned the dynamics when striking, simultaneously as preferred, the piece 621 that strikes of pendulum end is self-lubricating plastic construction, and plastic material is less to plastics wearing and tearing, can effectively prolong the life of button.

In order to realize sound production with a falling feeling, the knocking block 621 has a Z-shaped stepped structure and includes a lower knocking portion 621a and an upper knocking portion 621 b; when the button is pressed to enable the pendulum bob 62 to move downwards, the lower knocking portion 621a of the knocking block 621 contacts the limiting step 41 and accumulates tension of the torsion spring, meanwhile, the wedge-shaped pressing block 31 moves downwards to enable the pendulum bob to move transversely 62 to drive the lower knocking portion 621a of the knocking block to slide away from the limiting step 41, and when the lower knocking portion 621a of the knocking block slides away, the upper knocking portion 621b strikes the limiting step 41 under the action of the torsion spring. The unique pendulum structure can be used for triggering signals, can realize sound production of falling feeling, and greatly enhances the knocking hand feeling; meanwhile, the pendulum bob is a vertical movement trigger signal, sound production is realized through horizontal movement, and trigger and sound production are realized simultaneously in a limited light and thin space, which is not possessed by the traditional pendulum bob.

In order to realize signal output, a light emitting element and a light receiving element are further arranged in the key bottom case 2, the light emitting element and the light receiving element are arranged at the front end of a pendulum 62, and the pendulum is a light path switch for switching on and off a light path. When the pendulum bob moves downwards, the light path can be cut off, and a signal is obtained between the light-emitting element and the light-receiving element.

In order to realize signal output, a hall element is further arranged in the key bottom case 2, and the pendulum bob is a magnetic part for triggering the hall element. When the pendulum bob moves downwards, the magnetic piece is close to the Hall element, the magnetic flux changes, and the Hall element obtains a signal.

When the device is used, the elastic silica gel piece can realize the on-off of a signal path. In addition, when the key is pressed down, the male frame and the female frame move downwards by overcoming the elasticity of the elastic silica gel piece, and when the pendulum bob is not arranged, the torsional spring beats the limiting step to make a sound, so that the structure is simplified; when the pendulum bob and the torsion spring are pivoted together, the knocking block of the pendulum bob moves downwards along with the female frame, and the knocking block of the pendulum bob triggers the on-off of a signal path; after the key is released, the male frame and the female frame reset upwards under the action of the elastic force of the elastic silica gel piece, and the knocking block of the pendulum bob resets upwards along with the elastic force. This application both accessible elasticity silica gel spare realizes the break-make of signal path, can also realize the break-make of signal path through the pendulum simultaneously, has dual fail-safe's effect.

The traditional impact hammer structure with a sounding structure usually moves up and down, and requires a larger stroke; and the pendulum of this application adopts brand-new structure, and the pendulum can also transversely move about when moving about, sends the knock sound, has compromise trigger signal and has sent the knock sound, can provide splendid touch and sound of beating. The mechanical key is very suitable for long-term code words or users needing refreshing game texture.

The key is suitable for a thin-film key or a thin-film keyboard, the sounding piece is arranged, the hitting sound of the key can be realized, the ultra-thin key characteristic is met, and meanwhile, a simple single torsion spring structure can be adopted, and a torsion spring can be used for driving a pendulum bob to sound; the application can generate the trigger section falling feeling and simultaneously send out the knocking sound in the pressing process; torsional spring drive pendulum can also cooperate different electric elements to realize signal output, realizes multimode signal output, and the dual electric element guarantee of this application effectively prolongs button life-span and uses, further promotes user experience.

The above, only do the preferred embodiment of the present invention, not used to limit the present invention, all the technical matters of the present invention should be included in the protection scope of the present invention for any slight modification, equivalent replacement and improvement of the above embodiments.
