Embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing and specific embodiment to the utility model structure
Think of is explained in further detail.
Embodiment one：
As shown in accompanying drawing 1 ~ 3, the membrane keyboard that can be not only used for that the present embodiment is disclosed can also be used for the compound of PKB photoelectric keyboard
Mechanical switch, can be directly mounted on membrane keyboard, be fixed on by the middle plate 81 on keyboard directly over thin film switch structure, with
Thin film switch structure 9 is used cooperatively, and is silent switch.
Specifically, the compound mechanical switch includes upper lid 1, the base 2 matched with upper lid 1, button 3 and spring 4,
Firmly fastened between upper lid 1 and base 2 and be integral and be internally formed cavity, button 3, spring 4 are located in the cavity.The structure
Module integral form is formed, is easy to the installation between membrane keyboard to combine.When in use, client can be by simple by client
Design adjustment realize and used cooperatively with other keyboards.
In the present embodiment, for the ease of the mobile working of button 3, opening is offered on upper lid 1, the upper end of button 3 is by opening
Mouth extends the upper surface of lid 1, the keycap of keyboard（Not shown in figure）It is snapped in the upper end of button 3.One is offered in the bottom of base 2
Through hole 21, the lower end of button 3 is the cylinder extended downwardly, and cylinder extends the lower section of base 2 by the through hole and peaks at thin film switch
In structure.Spring 4 is in compressive state, between button 3 and the inwall of base 2.
When button 3 is pressed down, spring 4 is compressed, and the bottom surface of base 2 is stretched out in the lower end of button 3, and peaks at thin film switch structure
After upper triggering thin film switch structure work, release button 3, button moves up under the effect of spring 4 and returns back to original state.
For protective film construction of switch and raising pressing feel, the cylindrical end portions in the lower end of button 3 are cased with or one
Soft material contact 5 is injection molded with, the soft material contact can be soft silica gel or rubber sleeve etc., can effectively improve thin film switch knot
Structure service life and when making pressing feel more preferably, its concrete shape is unrestricted, can be and any shape of lower end form fit of button 3
Shape.Meanwhile, a shell fragment 6 is fixed with the madial wall of base 2, is provided with the side wall of button 3 and is gradually higher than the side wall of button 3 from the top down
Inclined plane 71, the bottom of inclined plane 71 be continuously extended with an angle of inclination be less than inclined plane 71 face 72 of saving up strength, save up strength face 72 with
The junction self-assembling formation fluted 73 of inclined plane 71, shell fragment 6 can top pressure be in inclined plane 71 and saves up strength on face 72.Moved down in button 3
During, the upper end of starting stage shell fragment 6 is acted on the face of saving up strength 72, is moved upwardly into as button 3 moves down shell fragment 6 along the face of saving up strength 72
The position of groove 73, the position makes whole button 3 move down middle formation interim card feel.When button 3 continue folding process in, on shell fragment 6
End is moved to diminish with inclined plane 71,3 times pressure resistances of button, so as to enhance feel of the button 3 during pushing.
In addition, in order that the present embodiment design compound mechanical switch there is dust reduction capability, set in the upper end periphery of button 3
The dust-proof wall 31 for being open and matching with upper lid 1 is equipped with, dust-proof wall 31 is upwardly extended higher than the upper end end face of button 3 along the edge of button 3, is prevented

One angle of inclination is less than the face 72 of saving up strength of inclined plane, and save up strength face 72 and the junction self-assembling formation fluted 73 of inclined plane 71.In work
Moving part 7 is as in the folding process of button 3, the upper end of starting stage shell fragment 6 is acted on the face of saving up strength 72, due to shell fragment 6 from bottom to top
Movable part is set to be upwarped close to shell fragment side the force of movable part 7.Moved upwardly into as movable part 7 moves down shell fragment 6 along the face of saving up strength 72
The position of groove 73, the position makes whole button 3 move down middle formation interim card feel.When movable part 7 continue folding process in, shell fragment 6
Upper end is moved to diminish with inclined plane 71,3 times pressure resistances of button, and now shell fragment 6 exerts a force to movable part 7 from the top down, movable part
7 are triggered swing, and movable part, which swings simultaneously to hit with button, sends sound.
In stable condition when movable part 7 is contacted with shell fragment 6 in order to improve, inclined plane 71 and face 72 of saving up strength are two, symmetrical position
In the side Bi Liang edges of movable part 7.
, can be by being arranged on button 3 symmetrical two as the connection between movable part 7 and button 3 in the present embodiment
Back-off 34 is caught in movable part 7 and realized, will not be described here.
Embodiment three：
As shown in Figure 8, what the present embodiment was disclosed can be not only used for the compound machine that membrane keyboard can also be used for PKB photoelectric keyboard
Tool is switched also in the improvement in structure in embodiment one, and the compound mechanical switch can also send sound during pressing
Sound, with interim card sense of touch.For compound mechanical switch structure in embodiment two, the present embodiment is mainly the structure of button 3
Changed, be specially：
The angled protrusions 64 for being gradually higher than button side walls from bottom to top are provided with the side wall of button 3, shell fragment upper end, which is peaked at, inclines
Tiltedly in projection 64, there is an arc groove 65 in the epimere of angled protrusions 64.In the folding process of button 3, the upper end of shell fragment 6 is inclined
Oblique raised 64 crimp, when button 3 is displaced downwardly in the arc groove 65 of shell fragment 6, resistance is larger forms interim card feel, works as button
Moving down makes shell fragment 6 be located at behind the extreme higher position of angled protrusions 64, and the upper end of shell fragment 6 departs from the percussion side wall of button 3 of angled protrusions 64 and sent
Sound.
The structure annexation and operation principle of the present embodiment miscellaneous part are consistent with embodiment two, do not do herein superfluous
State.
Example IV：
