Embodiment
Below will be with reference to the graphic the utility model of describing of enclosing for reaching employed technological means of purpose and effect; And below graphic cited embodiment be merely aid illustration; Your understand in order to juror, but that the technological means of this case is not limited to is cited graphic.
See also Fig. 1 and shown in Figure 2; The utility model one of provides the press-key structure 10 of specific embodiment; It comprises substrate 11, keycap 12 and connecting elements 13, in Fig. 1, in order to know the annexation of display base plate 11 and keycap 12, does not therefore show connecting elements shown in Figure 2 13; Connecting elements 13 is arranged between keycap 12 and the substrate 11; Connecting elements 13 is in order to support keycap 12, and binding keycap 12 and substrate 11, and the form and the kind of connecting elements 13 do not have certain limitation; The connecting elements 13 that present embodiment adopted is the scissors pin connecting structure of this area dealer common name, and such scissors pin connecting structure is staggered and two supports 131,132 (seeing also shown in Figure 2) formation that articulate each other by two.
This substrate 11 has substrate surface 111, and substrate surface 111 is parallel to first plane, is provided with first male member 112 in substrate surface 111; First male member 112 is perpendicular to first plane, and first male member 112 convexedly stretches in substrate surface 111, with Fig. 1; Substrate surface 111 is a horizontal plane, first male member, 112 vertical extent and convexedly stretch in substrate surface 111, and the material of substrate 11 is not limit; For example can adopt metal materials such as aluminium sheet, 112 of first male members are formed at substrate surface 111 with impact style.
This keycap 12 has relative keycap end face 121 and keycap bottom surface 122, and keycap bottom surface 122 is provided with corresponding two articulated part 123a, 123b towards substrate surface 111 in keycap bottom surface 122; And two trip 124a, 124b, the connecting elements 13 wherein top of a support 131 is articulated in articulated part 123a, 123b (as shown in Figure 2), and the top of another support 132 is sticked in trip 124a, the 124b; And the bottom of this two support 131,132 is articulated in the pin-jointed structure 113 of the set plural number of substrate 11; In addition, be provided with second male member 125 in keycap bottom surface 122, this second male member 125 is parallel to first plane and second male member 125 convexedly stretches in keycap bottom surface 122; The projected position of second male member 125 is positioned at outside first male member 112; First male member 112 of the utility model and form, size and the position of second male member 125 do not have certain limitation, as long as reach first male member 112 and second male member 125 can not interfered each other, with present embodiment; Second male member 125 is for being convexly set in the wherein fin of the side of an articulated part 123a; 112 sides of first male member corresponding to another articulated part 123b, generally speaking, keycap 12 adopts plastic cement material; Therefore, articulated part 123a, 123b, trip 124a, 124b and second male member 125 can with keycap 12 with plastic cement one ejection formation.
As shown in Figure 2, because the projected position of second male member 125 is positioned at outside first male member 112, that is second male member 125 and first male member 112 can not interfered each other; Therefore, assembler can be assembled in keycap 12 on the substrate 11, in other words smoothly; If when second male member 125 and first male member 112 were interfered each other, then keycap 12 can't be assembled in substrate 11, sees also press-key structure embodiment illustrated in fig. 3 20; It comprises substrate 21, keycap 22 and connecting elements 23, is provided with first male member 212 in substrate 21, is provided with second male member 225 in keycap 22; Second male member 225 and first male member 212 can not interfered each other, and the difference of present embodiment and Fig. 2 embodiment is, first male member 212 of present embodiment, the position of second male member 225; Just the opposite with the position of first male member 112 of Fig. 2 embodiment, second male member 125, therefore, if will the keycap 12 of Fig. 2 be assembled in the substrate 21 of Fig. 3 the time; Can produce situation as shown in Figure 4, second male member 125 can be interfered each other with first male member 212 and can't be assembled, in like manner; If in the time of will the keycap 22 of Fig. 3 being assembled in the substrate 11 of Fig. 2; Then produce situation as shown in Figure 5, second male member 225 can be interfered each other with first male member 112 and can't be assembled, and reaches the foolproof function of assembling keycap 12,22 by this.
See also Fig. 6 and shown in Figure 7; The press-key structure 30 of the 3rd specific embodiment that the utility model provides; It comprises substrate 31, keycap 32 and connecting elements 33; Be provided with corresponding two articulated part 323a, 323b and two trip 324a, 324b in keycap bottom surface 322; Protrude out respectively in the side of two articulated part 323a, 323b and to be provided with the second male member 325a, 325b, these two second male member 325a, 325b side by side and have a distance are provided with two first male member 312a, 312b in the substrate surface 311 of substrate 31; These two first male member 312a, 312b are side by side and have a distance; The projected position of the second male member 325a, 325b be positioned at the first male member 312a, 312b each other away from an end outside because the first male member 312a, 312b can not interfere with the second male member 325a, 325b each other, so can successfully keycap 32 be assembled on the substrate 31.
See also press-key structure embodiment illustrated in fig. 8 40; It comprises substrate 41, keycap 42 and connecting elements 43; Be provided with two second male member 425a, 425b in keycap 42, be provided with two first male member 412a, 412b in substrate 41, the projected position of the second male member 425a, 425b is between the first male member 412a, 412b; Because the first male member 412a, 412b and the second male member 425a, 425b can not interfere each other, therefore can successfully keycap 42 be assembled on the substrate 41.
Know by Fig. 7 and embodiment illustrated in fig. 8; If in the time of will the keycap 32 of Fig. 7 being assembled in the substrate 41 of Fig. 8; Can produce situation as shown in Figure 9, the second male member 325a, 325b can interfere each other and can't assemble with the first male member 412a, 412b respectively, in like manner; If in the time of will the keycap 42 of Fig. 8 being assembled in the substrate 31 of Fig. 7; Then produce situation shown in figure 10, the second male member 425a, 425b can interfere and can't assemble with the first male member 312a, 312b each other, reach the foolproof function of assembling keycap 32,42 by this.
The foregoing description is an illustrative examples with single press-key structure all, and when the foregoing description was applied to keyboard, it is identical that it implements structure; Embodiment with Fig. 2; Substrate 11 is strengthened the required keyboard size of cooperation, can plural keycap 12 be set, be equipped with connecting elements 13 between each keycap 12 and the substrate 11 in substrate 11; Be provided with first male member 112 in the substrate 11 corresponding required positions that keycap 12 is set; Each keycap 12 has second male member 125, and the projected position of second male member 125 of each keycap 12 is positioned at outside first male member 112 of pairing substrate 11, and assembler can be assembled in keycap 12 on the substrate 11 one by one; If the assembler mistake is taken the keycap 22 of Fig. 3, then can't be assembled on the substrate 11 at all.
In sum, press-key structure that the utility model provides and keyboard owing to have the fool proof design, therefore can be avoided the keycap assembly defect, not only can improve the product yield, can avoid the keycap damage simultaneously or change man-hour and the cost that keycap is wasted.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
