Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
See Fig. 1 and Fig. 5, according to press-key structure of the present invention, comprise: rectangular box 10, rectangular box 10 has upper surface 11 and lower surface 12 and the medial surface 13 be arranged between upper surface 11 and lower surface 12 and lateral surface 14, button 80 is positioned at rectangular box 10, and button 80 side is connected with medial surface 13 by bearing band 20; Bearing band 20 comprises two sheet strips be connected with rectangular box 10 with button 80 respectively.By the bearing band of button 80 is designed to rectangular plates, the design of such button can greatly reduce mould correction number of times relative to the bearing band of original " L " shape, and bearing band not easily sticky front mould, and the longer service life of this bearing band " L " shape bearing band original compared with it, Long-Time Service is indeformable.
See Fig. 1 and Fig. 5, rectangular box 10, bearing band 20 and button 80 are structure as a whole.Press-key structure is by ABS material injection mo(u)lding, and preferably, the overall press-key structure of the present embodiment is a square structure, also can select circular or other shapes according to the concrete shape of related accessory.
See 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, and preferably, long is 5.8mm, and wide is 2.5mm, and thick is 0.8mm, and the distance between two bearing bands 20 is 4mm.Compared with conventional " L " type bearing band, the design of the bearing band 20 of the present embodiment can greatly reduce mould correction number of times, bearing band 20 because of this kind of design compares conventional " L " type bearing band regular shape and thickness is thin, not easily sticky front mould, the longer service life arranged than other bearing bands of two bearing bands 20 of the present embodiment simultaneously, and indeformable.
See Fig. 1, Fig. 2, Fig. 3 and Fig. 5, the relative both sides of rectangular box 10 lateral surface 14 are respectively arranged with hold-down screw post 40, and hold-down screw post 40 is tubular cylinder.Rectangular box 10 both sides have two cylindrical such project organizations simple, easy to operate.Panel body has the open tubular column of a disposed thread and hold-down screw post 40 with the use of, first hold-down screw post 40 is enclosed within the open tubular column of this panel body, above again pcb board being arranged on, then with screw, rectangular box 10, panel body and pcb board are locked together.
See Fig. 1, Fig. 2 and Fig. 5, lower surface 12 is provided with the pillar 50 vertical with lower surface 12.On rectangular box 10,8 are had specially for devising the pcb board pillar 50 of pcb board straightening in the present embodiment, it is cylinder design, preferably the pillar 50 of the present embodiment is highly 14.7mm, diameter is 3mm, if desired also can 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 when avoiding the element on pcb board, 8 columniform pcb board pillars 50, when assembling, pcb board pillar 50 withstands pcb board, prevents pcb board to be out of shape.Because distortion is inevitable after pcb board crosses 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 relevant position constant distance, can not deform, also user can not be made to have handfeel of keys difference even if press-key structure and pcb board spacing increase, customer experience is good.
See Fig. 1, Fig. 3 and Fig. 5, button 80 is connected with button effect post 30 relative to the opposite side of bearing band 20, button effect post 30 is perpendicular with lower surface 12.Preferably, button effect post 30 is be highly the columniform structure of 6.8mm, relative to existing design button effect post being arranged on the center of button, button effect post 30 is arranged on the side of button 80 by the present embodiment, feel can be made better, and its glue-feeder is at button effect post root, the height of button effect post can reach 30mm, and appearance can not be caused to shrink.
See Fig. 1, Fig. 4 and Fig. 5, press-key structure also comprises fixture 60, and perpendicular with lateral surface 14 on the lateral surface 14 being arranged on rectangular box 10, fixture 60 comprises two fixed legs 61 be parallel to each other.The inner side that two fixed legs 61 are relative is provided with the breach 611 for locating button.The fixture 60 melting process step design is two rectangle fixed legs 61, and preferably, the inner side that fixed leg 61 is relative is provided with semicircular indentations, and its effect fixes with the circular stanchions on cover, makes to melt operation and is well on.
See Fig. 1, also comprise and melt fixed structure 70, be arranged on upper surface 11, melt fixed structure 70 for through-hole structure.Rectangular box 10 has 8 circular through holes for melting fixed structure 70, press-key structure and cover melt and are fixed together by the operation that adopts this specifically to melt, and decrease button and fix required screw.Press-key structure and cover are fixed more firm.
See Fig. 1 and Fig. 5, rectangular box 10 inside has multiple crossbeam 15 be connected with button 80, and button 80 is connected on crossbeam 15 by bearing band 20, and is connected with medial surface 13 by crossbeam 15.In order to different needs can be met, more button 80 is installed, multiple crossbeam 15 can be set in rectangular box 10 inside, to reach the object of the more buttons 80 of installation.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
By the bearing band of button is designed to rectangular plates, and be integrated with fixed frame, the design of such button can greatly reduce mould correction number of times relative to the bearing band of original " L " shape, and bearing band not easily sticky front mould, and the longer service life of this bearing band " L " shape bearing band original compared with it, Long-Time Service is indeformable.Under the prerequisite ensureing simplified structure, can controlling distortion, ensure moulding quality.Simultaneously relative to common press-key structure, fixing required screw is less, uses and melts fixing design; Button and pcb board separate to be assembled, and is convenient to control to install quality, saves like this and assembles required buckle with pcb board, make Mold Making simple; Press-key structure and pcb board spacing adjustable; By the design of button effect post at side, feel so not only can be made better, and its glue-feeder is at button effect post root, and appearance can not be caused to shrink.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, 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 amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
