The object of the invention is to be realized by following technical proposals: a kind of press-key structure, comprise keycap assembly, thin film circuit, PCB, described keycap assembly is made up of silica gel shell and printing opacity skeleton, the bottom surface of described printing opacity skeleton is provided with multiple touch-control projection, described thin film circuit comprises circuit layer, insulating barrier, lower circuit layer, described insulating barrier is interval with the trigger region of multiple hollow out, the trigger region of described multiple hollow out is corresponding with described multiple touch-control projection to be arranged; Described thin film circuit is electrically connected with described PCB.
Further, described silica gel shell and substrate integrated injection molding, arrange the wide cone barrel elastic arm of narrow end opening suitable for reading between described silica gel shell and described substrate.
Further, between the trigger region of described multiple hollow out, bonding pad is set.
Further, described thin film circuit is provided with loophole, and described PCB installs LED light source, and described LED light source is corresponding with described loophole to be arranged.
Further, the thickness of the touch surface of described silica gel shell is 1 ~ 2 millimeter.
Further, described printing opacity skeleton is formed by materials processing arbitrary in Merlon, polymethyl methacrylate, styrenic block copolymer, cellulosic plastics, styrene methyl methacrylate.
The present invention compared with prior art tool has the following advantages:
1, in the present invention, the printing opacity skeleton bottom surface of keycap assembly is provided with the multiple touch-controls projections corresponding with the trigger region of thin film circuit, namely ensure effective touch-control of button, can prevent from again keycap assembly after pressing completely and form negative pressure between thin film circuit and affect the resilience of keycap assembly resetting.
2, narrow end opening suitable for reading wide cone barrel elastic arm is set between silica gel shell and substrate in the present invention, directly determines that the force size of pressing key cap assembly and the resilience of keycap assembly reset by elastic arm, the sense of touch of button is effectively promoted.
3, printing opacity skeleton in the present invention strengthens the integral rigidity of keycap assembly, strengthens the feedback of touch-control result, the thickness of the touch surface of silica gel shell is reduced, the light transmission of enhancing keycap assembly, make on keycap assembly be identified in the dark environment of light more eye-catching.
4, structure of the present invention is simple, does not have guide frame and balancing pole, and be more convenient for processing and installation, can reduce production cost simultaneously.
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.

Embodiment
See Fig. 1 to Fig. 5, a kind of press-key structure, comprise keycap assembly, thin film circuit 8, PCB, described keycap assembly is made up of silica gel shell 1 and printing opacity skeleton 2, the bottom surface of described printing opacity skeleton is provided with multiple touch-control projection 3, described thin film circuit 8 comprises circuit layer 4, insulating barrier 5, lower circuit layer 6, described insulating barrier is interval with the trigger region 7 of multiple hollow out, and the trigger region of described multiple hollow out is corresponding with described multiple touch-control projection to be arranged; Described thin film circuit 8 is electrically connected with described PCB 9.
See Fig. 1, described printing opacity skeleton 2 is the shell structure of bottom opening, and the shape of end face can be circle, triangle, square and irregularly shaped etc.Described silica gel shell 1 is wrapped in the outside of described printing opacity skeleton, and the shape of described silica gel shell is close with the shape of described printing opacity skeleton.The end face of described silica gel shell is touch surface.See Fig. 4, Fig. 5, the present embodiment is described for round key cap assembly, the bottom surface of described printing opacity skeleton 2 is annular, multiple touch-control projection 3 is evenly provided with along on this annular bottom surface, the insulating barrier 5 of described thin film circuit is interval with the trigger region 7 of the hollow out of multiple arc section shape, the trigger region of described multiple hollow out is corresponding with described multiple touch-control projection to be arranged.By any touch area of the touch surface of pressing silica gel shell, upper circuit layer can be made to contact to produce with lower circuit layer and trigger the signal of telecommunication by the trigger region of correspondence, be transferred to PCB and complete effective touch-control.
Printing opacity skeleton strengthens the integral rigidity of keycap assembly, and the thickness of the touch surface of silica gel shell is reduced, the light transmission of enhancing keycap assembly, make on keycap assembly be identified in the dark environment of light more eye-catching.In the present embodiment, the thickness of the touch surface of described silica gel shell is 1 ~ 2 millimeter.The thickness of the touch surface of described silica gel shell can be selected between 1 ~ 2 millimeter, most preferred, and the thickness of the touch surface of described silica gel shell is 1.5 millimeters.
