Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
As shown in Figures 1 to 4: press-key structure includes key main body 1, positioning device 2, resilient mounting 3, stroke control device
4, guiding device 5 and key device 6；Key main body 1 is divided into key main body edge part according at a distance from 1 center of key main body
11, key main body middle part 12 and key main body center portion 13；Display structure 14 is provided on the outside of key main body 1；Positioning device 2 is arranged
On 11 inside of key main body edge part, positioning device 2 includes flexible positioning that is perpendicular with key main body 1 and connecting
Piece 21 and the location hook 22 that 21 end of locating plate is arranged in, the quantity of positioning device 2 are at least three and are distributed in key main body 1
Different directions are to guarantee stable position, each 2 uneven distribution of positioning device or realization foolproof function of different sizes；Resilient mounting
3 are arranged on the inside of key main body edge part 11 above and than positioning device 2 closer to 1 center of key main body, and 3 shape of resilient mounting is
Strip and there is elasticity, 3 one end of resilient mounting connect with key main body 1 and prolongs along 1 outer profile side of key main body is inwardly angled
It stretches；Stroke control device 4 be arranged on the inside of key main body edge part 11 it is upper and than positioning device 2 closer to 1 center of key main body,
