During pressing, press section 51 is contacted with the protrusion 71 of V-arrangement elastic slice first, during button 5 continues to move down, press section
51 continue to act on protrusion 71, at this point, V-arrangement elastic slice is compressed, elastic deformation occurs, to generate elastic potential energy, button 5 after
Continuous to be moved downward to behind raised 71 highest points, 51 pairs of press section protrusion 71 is not having active force, at this point, the bullet of V-arrangement elastic slice
Property potential energy be released, V-arrangement elastic slice pop up hit upper housing 41 lower surface, so as to generate sound and vibration, therefore
During push button 5, it can hear that sound, finger can experience vibration, so as to increase the experience of user.
As shown in figs. 3 and 5, the fixed iron plate 2, which is equipped with, is passed through by axis and LED light group 8 for independent with sound
Hole, the independent band sound are pressed and are equipped with buckle on the outside of axis, independent to pass through the hole on fixed iron plate 2 by axis with sound and pass through
Buckle and fixed iron plate 2 are fixed, and pcb board 1 is equipped with and the independent opening being adapted to sound by axis edge, independent band sound
After pressing the opening that axis passes through on the hole and pcb board of fixed iron plate, it is independent with sound by being sunken in opening under the lower case of axis, lead to
It is fixed with fixed iron plate 2 to cross buckle, at this point, it is independent with sound by being sunken in opening under the lower case 42 of axis, PCB can be reduced
Plate 1 to independent band sound presses the distance between axis top, so as to reduce the whole height of keyboard.At this point, independent band
Sound is not needed to weld as between axis and pcb board 1, independent to be fixed by the buckle of side with fixed iron plate with sound by axis,
It is installed and is fixed with snap, simplify production process, reduce assembling cost, and after-sales service is convenient.
Be equipped with shading piece (being not drawn into figure) in the outside of upper housing 41, the shading piece in the outside of LED light group 8,
In, shading piece can be integrally formed with upper housing 41 or lower case 42, can also be provided separately, and be arranged on the outside of LED light group 8 and hidden
Light part surrounds LED light group 8, can be formed and be interfered to avoid the LED light group 8 between different key, cause the biography of error signal
It is defeated.
As shown in Figure 3, wherein independent band sound, which is pressed, is equipped with buckle on the outside of axis, independent band sound passes through buckle by axis
It is fixed with fixed iron plate 2.Further, pcb board 1 be equipped with independent opening be adapted to sound by axis edge, it is described only
Vertical band sound, which presses axis and fixes bottom after iron plate 2 is fixed, to be located in opening.LED light group 8 is directly connect with pcb board 1, can be incited somebody to action
The input of 5 structure of button and signal separates, meanwhile, button 5 and shell 4 are fixed by snap on fixed iron plate 2, in PCB
Plate 1 is equipped with the opening that can be passed through for shell 4, at this point, independent band sound can be totally separated from by axis and pcb board 1,
So as to simplify installation process.
As shown in Figure 3, wherein scissor 3 is fixed on fixed iron plate 2, is equipped with keycap (in figure on the top of scissor 3
It is not drawn into), when pressing keycap, the balance of keycap can be kept by scissor 3, meanwhile, it is allowed in pressing keycap to moving down
When dynamic, keycap act on it is independent pressed on the button 5 of axis with sound, so as to control the independent button 5 for pressing axis with sound
It moves down.
In free state, through-hole 9 is not blocked, and can be connected between LED light group 8, can carry out the transmission of light,
During moving down button 5, the guide part 52 of button 5 can will block at through-hole 9, LED light group 8 it is separated, that is, press
Button 5 can form access or disconnection during moving up and down between LED light group 8, so as to form the defeated of push button signalling
Enter.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
