Embodiment
Extremely shown in Figure 5 referring to Fig. 1, a kind of shrapnel device that is applicable to ultra-thin key, comprise a base plate 1, one group of base plate perforate 103 is arranged on the base plate 1, both sides, base plate 1 front and back projection forms one group of baffle plate 102, and wherein, this shrapnel device also comprises a sliding panel 101 that is fitted in base plate 1 upper surface, have one group of key hole 108 on the sliding panel 101, sliding panel 101 lower surfaces have one group of inclined-plane post 104 that falls in the corresponding base plate perforate 103.This shrapnel device also comprises one group of U-shaped shell fragment 110 corresponding with key hole, this group U-shaped shell fragment 110 is whole rectangular, the middle part of U-shaped shell fragment 110 upwards forms shallow U-shaped protuberance along the rectangle long side direction, whole U-shaped shell fragment 110 longitudinal cross-sections are shallow U-shaped, overall structure is similar to the chi band of firm tape measure, the shallow U-shaped structure of this kind just can be so that after the left and right sides of U-shaped shell fragment 110 minor face be bridged on key hole 108 the right and lefts, to a certain degree pressing of external force can be born in the middle part of U-shaped shell fragment 110, after the power of pressing surpasses some values, U-shaped shell fragment 110 is bending suddenly, and unlike shell fragment the same, slight pressure just begins deformation bending, thus the shallow U-shaped structure of this kind can guarantee whole U-shaped shell fragment 110 press feel and conventional keyboard silicon rubber cup to press feel similar.Similarly, the middle part of U-shaped shell fragment 110 can also form shallow V-arrangement protuberance along the rectangle long side direction, and the V-arrangement protuberance is consistent with the effect of shallow U-shaped protuberance.
The left and right sides minor face of this group U-shaped shell fragment 110 is bridged on 108 the right and lefts of corresponding key hole, and the right and left of sliding panel key hole 108 has stopper slot 109, the left and right sides minor face of U-shaped shell fragment 110 is bridged in the stopper slot 109, after stopper slot 109 can guarantee the bending downwards of U-shaped shell fragment 110 mid portions, U-shaped shell fragment 110 integral body can left and right displacement.
Sliding panel 101 moves right can be so that inclined-plane post 104 shifts out base plate perforate 103, and the chamfered portion of inclined-plane post 104 can guarantee to skid off smoothly base plate perforate 103, after inclined-plane post 104 shifts out base plate perforate 103, can support sliding panel 101 makes itself and 1 of base plate form void layer, the mid portion of assurance U-shaped shell fragment 110 has the space of downward bending, sliding panel 101 is moved to the left can be so that inclined-plane post 104 moves into base plate perforate 103, and this moment, sliding panel 101 was fitted with base plate 1.
When sliding panel 101 moves right and forms void layer with base plate 1, press the mid portion of U-shaped shell fragment 110, the mid portion of U-shaped shell fragment 110 bending downwards falls in the key hole 108, both sides still are bridged on the right and left of key hole 108, but perk slightly, whole U-shaped shell fragment 110 is not subjected to displacement.
The lower surface of U-shaped shell fragment 110 has conductive layer, and base plate 1 upper surface is installed the thin film circuit layer, and after the bending downwards of U-shaped shell fragment 110 middle parts, conductive layer is energy conducting membrane circuit layer just, and the keyboard chip just can be identified this button and be pressed.
Gapped between U-shaped shell fragment 110 and the key hole 108, can guarantee the normal mounting of the device of similar keyboard shear shank and so on, after installing, just can form normal keyboard structure.
Therefore, all modification and conversion of carrying out according to main design of the present utility model all should drop within the protection range of the present utility model.
