Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Referring to Fig. 1 and Fig. 5, according to press-key structure of the present invention, comprise: rectangle framework 10, rectangle framework 10 have upper surface 11 and lower surface 12 and be arranged on upper surface 11 and lower surface 12 between medial surface 13 and lateral surface 14, button 80 is positioned at rectangle framework 10, and button 80 1 sides are connected with medial surface 13 by bearing band 20; Bearing band 20 comprises two sheet bands that are connected with rectangle framework 10 with button 80 respectively.Be designed to rectangular plates by the bearing band with button 80, the design of such button can greatly reduce mould correction number of times with respect to the bearing band of original " L " shape, and bearing band is difficult for sticking front mould, and this bearing band uses indeformable than the longer service life of its original " L " shape bearing band for a long time.
Referring to Fig. 1 and Fig. 5, rectangle framework 10, bearing band 20 and button 80 are structure as a whole.Press-key structure is by the injection mo(u)lding of ABS material, and preferably, the whole press-key structure of present embodiment is a square structure, also can select circular or other shapes according to the concrete shape of related accessory.
Referring to Fig. 1 and Fig. 5, the bearing of trend of bearing band 20 is parallel with upper surface 11.Bearing band 20 is two laminated structures, preferably, long is 5.8mm, and wide is 2.5mm, and thick is 0.8mm, and the distance that two bearing bands are 20 is 4mm.Compare with " L " type bearing band commonly used, the design of the bearing band 20 of present embodiment can greatly reduce mould correction number of times, because the bearing band of this kind design 20 is than " L " type bearing band regular shape and thin thickness commonly used, be difficult for sticking front mould, simultaneously two bearing bands 20 of present embodiment longer service life than other bearing bands is set, and indeformable.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 5, the relative both sides of rectangle framework 10 lateral surfaces 14 are respectively arranged with hold-down screw post 40, and hold-down screw post 40 is the tubular cylinder.Rectangle framework 10 both sides have two cylindrical such project organizations simple, easy to operate.There are open tubular column and the hold-down screw post 40 of a built-in screw thread to be used on the panel body, at first hold-down screw post 40 is enclosed within on the open tubular column of this panel body, above again pcb board being installed in, then with screw rectangle framework 10, panel body and pcb board are locked together.
Referring to Fig. 1, Fig. 2 and Fig. 5, be provided with the pillar 50 vertical with lower surface 12 on the lower surface 12.There are 8 specially for having designed the pcb board pillar 50 of pcb board straightening in rectangle framework 10 in the present embodiment, it is cylinder design, preferably the pillar 50 of present embodiment highly is 14.7mm, diameter is 3mm, in case of necessity also can be according to the numerical value of actual conditions setting height and diameter, the position of pillar 50 is arranged on the both sides of button effect post 30 as far as possible in the situation of avoiding the element on the pcb board, 8 columniform pcb board pillars 50, when assembling, pcb board pillar 50 withstands pcb board, prevents the pcb board distortion.Because distortion was inevitable after pcb board was crossed the tin stove, the design is by screw and the extruding of pillar 50 both sides, make the hand of pcb board and button 80 by the relevant position constant distance, can not deform, even the distance increase can not make the user that handfeel of keys difference is arranged yet between press-key structure and pcb board, customer experience is good.
Referring to Fig. 1, Fig. 3 and Fig. 5, the opposite side with respect to bearing band 20 on the button 80 is connected with button effect post 30, and button effect post 30 is perpendicular with lower surface 12.Preferably, button effect post 30 is highly to be the columniform structure of 6.8mm, with respect to the existing design that button effect post is arranged on the center of button, present embodiment is arranged on button effect post 30 side of button 80, can make feel better, and its glue-feeder is at button effect post root, and the height of button effect post can reach 30mm, and can not cause appearance to shrink.
Referring to Fig. 1, Fig. 4 and Fig. 5, press-key structure also comprises fixture 60, is arranged on the lateral surface 14 of rectangle framework 10 and perpendicular with lateral surface 14, and fixture 60 comprises two fixed legs 61 that are parallel to each other.Two fixed leg 61 relative inboards are provided with for the breach 611 of locating button.The fixture 60 that is melting operation design is two rectangle fixed legs 61, and preferably, fixed leg 61 relative inboards are provided with semicircle breach, its effect be with cover on circular stanchions fix, molten operation is well on.
Referring to Fig. 1, also comprise molten fixed structure 70, be arranged on the upper surface 11, melt fixed structure 70 and be through-hole structure.The through hole of 8 circles is arranged for melting fixed structure 70 in rectangle framework 10, adopt this specifically melting operation and press-key structure and cover are being melted be fixed together, reduced the fixing required screw of button.It is more firm that press-key structure and cover can be fixed.
Referring to Fig. 1 and Fig. 5, rectangle framework 10 inside have a plurality of crossbeams 15 that are connected with button 80, and button 80 is connected on the crossbeam 15 by bearing band 20, and is connected with medial surface 13 by crossbeam 15.In order to satisfy different needs, more button 80 is installed, can a plurality of crossbeams 15 be set in rectangle framework 10 inside, to reach the purpose of the more buttons 80 of installation.
As can be seen from the above description, the above embodiments of the present invention have realized following technique effect:
Be designed to rectangular plates by the bearing band with button, and be integrated with fixed frame, the design of such button can greatly reduce mould correction number of times with respect to the bearing band of original " L " shape, and bearing band is difficult for sticking front mould, and this bearing band uses indeformable than the longer service life of its original " L " shape bearing band for a long time.Under the prerequisite that guarantees simplified structure, can control distortion, guarantee the moulding quality.With respect to common press-key structure, fixing required screw is less simultaneously, uses and is melting fixedly design; Button separates assembling with pcb board, is convenient to control quality is installed, and saves like this with pcb board and assembles required buckle, makes Mold Making simple; The adjustable joint of distance between press-key structure and pcb board; At side, so not only can make feel better button effect post design, and its glue-feeder is at button effect post root, and can not cause appearance to shrink.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
