Abstract
An improved keyboard key structure comprises a shell body of the keyboard, a flexible printed circuit, a cushion, a middle plate, a key rod and a key cap, wherein the entire height of the key rod is higher than the combined thickness of the flexible printed circuit, the cushion and the middle plate; four corners of the bottom surface of the key rod are respectively provided with a protruding column, the flexible printed circuit corresponding to the position of the protruding column and perforation and a concave part which are arranged on a cushion and is kept within the compression range of the cushion when the protruding column is pressed on the shell body of the key board. The place of the protruding column are respectively provided with a penetrating hole and a concave part, the penetrating hole and the concave part can not exceed the compressing scope of the cushion when the protruding rod contacts the shell body of the keyboard. The utility model is convenient to install, thereby saving the working hour.
Description
The utility model relates to a kind of keyboard press button structure, can each part be assembled in regular turn during especially a kind of assembling from bottom to top and be integral improved keyboard press button structure simple in structure, easy to assembly.
General traditional keyboard structure, it includes keyboard case at least, flexible circuit board, cushion, middle plate, members such as key post and keycap, yet, cause is the relation of each parts design wherein, cause after when combination needs earlier keycap and key post made up one by one, place the hole of plate institute correspondence position again, the middle plate that key post and keycap will be housed is then installed cushion (or elastomer) and flexible circuit board etc. conversely, even be combined and instant and the support strength of strengthening flexible circuit board, fixed a metal base plate in the flexible circuit board bottom surface again, need once more the member integral inverted after the aforementioned combination to be come to be assembled on the keyboard case, just can finish the assembling of keyboard.
Above-mentioned known keyboard structure, main because the combination thickness of the middle plate of height of key post and cushion, flexible circuit board is little, so keycap can't in the end assemble, and after needing earlier it is contained in key post and middle plate, just can refill other part.Cause known configurations when assembling, must toss about, thereby cause workflow to have some setbacks, waste man-hour and increase assembly cost.So, this is had really again improved necessity.
Because of the defective in the design, the inconvenience when causing assembling studies intensively the inventor at known keyboard structure, and its people of union is engaged in this field for many years and makes and the experience that designs, and finally designs a kind of brand-new improved keyboard and makes structure.
The purpose of this utility model is to provide a kind of keyboard, during especially a kind of assembling, goes up assembling in regular turn by the keyboard part bottom and finishes, and can shorten assembling man-hour, reduces the improved keyboard press button structure of manufacturing cost.
Another purpose of the present utility model is to provide a kind of improved keyboard press button structure, and flexible circuit board wherein directly supports by keyboard case, thereby can reduce part and assembling man-hour of base plate.
For achieving the above object, a kind of improved keyboard press button structure that the utility model proposes, include keyboard case, flexible circuit board (three-layer type), cushion, middle plate, key post and keycap, wherein, the whole height of key post is greater than the combination thickness of flexible circuit board, cushion and middle plate, and respectively be provided with a projection at these four corners in key post bottom surface, and be respectively equipped with perforation and the depressed part that does not exceed the compressible scope of cushion when the projection contact during to keyboard case yet on corresponding to the flexible circuit board of projection position and cushion.
Characteristics of the present utility model and advantage are: because key post height of the present utility model is greater than the thickness sum total of middle plate and cushion, flexible circuit board, and respectively be provided with the projection that can pass flexible circuit board in four corners, key post bottom surface, make this key post when being forced into the end, can be on keyboard case by the projection contact, the deflection that prevents key post compressing cushion exceeds the compression zone of its expectation, guarantees the function of flexible circuit board therebetween; And its upper end can slightly be given prominence to outside the hole, cave of middle plate when the key post presses down, the clinching gap when this moment, it still had keycap and key column combination; And because described keycap can combine with the key post after other part all makes up again, the time needn't as known configurations, toss about in assembling, therefore, can be from bottom to top Rapid Combination in regular turn, reduce assembly cost.The utility model is easy to assembly, saves man-hour, even must not add a metal base plate again, can further reduce cost.
For making your juror more deep understanding and understanding can be arranged, lift a most preferred embodiment and conjunction with figs. now and be described in detail as follows structure of the present utility model, device and feature thereof:
Fig. 1 is a three-dimensional exploded view of the present utility model;
Fig. 2 is the singly-bound part three-dimensional exploded view in the utility model;
Fig. 3 is a combination section of the present utility model.
Figure number simple declaration in the accompanying drawing: 10, keyboard case 20, flexible circuit board 30, cushion 40, middle plate 50, key post 60, keycap 21, perforation 31, depressed part 41, hole, cave 51, projection
Please consult Figure 1 and Figure 2 earlier, a kind of improved keyboard press button structure that the utility model proposes includes keyboard case 10, flexible circuit board 20, cushion 30, middle plate 40, key post 50 and keycap 60.
Wherein the whole height of key post 50 is greater than the combination thickness of flexible circuit board 20, cushion 30 and middle plate 40, and respectively be provided with a projection 51 at these four corners in key post 50 bottom surfaces, on corresponding to the flexible circuit board 20 of projection 51 positions and cushion 30, be respectively equipped with perforation 21 and depressed part 31, do not exceed the normal compressible scope of cushion 30 when making these projection 51 contacts yet to keyboard case 10.
During the said structure assembling (as shown in Figure 3), because the height of wherein key post 50 is greater than the thickness sum total of middle plate 40 and cushion 30, flexible circuit board 20, and respectively be provided with projection 51 in four corners, key post 50 bottom surfaces, its depressed part 31 that can oppress cushion 30 easily passes the perforation 21 of flexible circuit board 20, make this key post 50 when being forced into the end, by projection 51 contacts on keyboard case 10, and the deflection that prevents key post 50 central authorities compressing cushion 30 exceeds the compression zone of its expectation, to guarantee the function of flexible circuit board 20 therebetween.And when key post 50 presses down its upper end can be slightly outstanding in outside the hole, cave 41 of plate 40 segment distance (when keycap 60 is assembled on this keyboard structure and presses down, between keycap 60 bottom surfaces and middle plate 40 end faces, still have a space), it can be had keycap 60 is combined in clinching gap on the key post 50, and then keycap 60 is stayed just be assembled at last on the key post 50, reach above-mentioned keyboard case 10, flexible circuit board 20, cushion 30, middle plate 40, assemblies such as key post 50 and keycap 60 are the purpose of Rapid Combination in regular turn from bottom to top, and then reaches the purpose that reduces assembly cost.
Therefore, the utility model needn't be tossed about as known configurations when assembling because keycap 60 can combine with key post 50 after other part all makes up again, and is easy to assembly, saves man-hour, even must not add a metal base plate again, can further reduce cost.
