With reference to the accompanying drawings embodiment of the present utility model is described.The element described in an accompanying drawing of the present utility model or a kind of execution mode and feature can combine with the element shown in one or more other accompanying drawing or execution mode and feature.It should be noted that for purposes of clarity, accompanying drawing and eliminate expression and the description of parts that have nothing to do with the utility model, known to persons of ordinary skill in the art and process in illustrating.
Below will with a plurality of execution modes of graphic exposure the utility model, as clearly stated, the details in many practices will be explained in the following description.But should be appreciated that, the details in these practices is not applied to limit the utility model.That is, in the utility model some embodiments, the details in these practices is non-essential.In addition, for the purpose of simplicity of illustration, some known usual structures and assembly illustrate it by the mode simply illustrated in the drawings.
Please refer to Fig. 1 to Fig. 4.Fig. 1 is the stereogram of the keyboard 1 of the utility model one execution mode.Fig. 2 is the partial enlarged drawing of Fig. 1.Fig. 3 is the generalized section of Fig. 2 along line segment 3-3 '.Fig. 4 is the partial enlarged drawing of Fig. 3.
As shown in Figures 1 to 4, in present embodiment, keyboard 1 comprises base plate 10, a plurality of button 12, upper caldding layer 14 and lower caldding layer 16.Each button 12 comprises coupling assembling 120 and keycap 122.Coupling assembling 120 is arranged on base plate 10.Keycap 122 is arranged on coupling assembling 120, and can to drive and opposed bottom 10 is elevated by coupling assembling 120.In an execution mode, the coupling assembling 120 of button 12 is scissor coupling assembling, but the utility model is not as limit.In another execution mode, coupling assembling 120 also can be dome-shaped syndeton or run-in index link assembly.
In the present embodiment, keyboard 1 has physical switches structure (not shown), but the utility model is not as limit.In practical application, keyboard 1 also can be force-sensing resistor formula keyboard.
In the present embodiment, base plate 10 is FR-4 supporting bracket, but the utility model is not as limit.
As shown in Figure 1 to Figure 3, the upper caldding layer 14 of keyboard 1 covers on button 12, and comprises hot-forming portion 140, a plurality of press section 142 and projection 144.Hot-forming portion 140 comprises the marginal zone 140a and Mang Xian district 140b that separate mutually.Press section 142 connects hot-forming portion 140, and overlapped on the keycap 122 of button 12 respectively.Marginal zone 140a is around press section 142.Press section 142 one of them around Mang Xian district 140b.Projection 144 is arranged on Mang Xian district 140b.The lower caldding layer 16 of keyboard 1 is arranged on base plate 10 times, and is connected with upper caldding layer 14 and forms accommodation space S.Keyboard 1 is coated in accommodation space S.
In one embodiment, projection 144 is different with the material of press section 142.
For example, according to general popular use habit, around Mang Xian district 140b press section 142 corresponding to button 12, can be the J key corresponding to right hand forefinger, or the F key corresponding to left index finger, but the utility model be as limit.
In the manufacture process of upper caldding layer 14, mainly comprise two steps: hot-forming step and producing lug step.Wherein, hot-forming portion 140 can complete via single hot-forming step with press section 142.Specifically, manufacturer, in hot-forming step stage, by the downward hot pressing in position of marginal zone 140a and Mang Xian district 140b, makes it recessed relative to press section 142.On the contrary, after hot-forming, press section 142 is then convex relative to the position of marginal zone 140a and Mang Xian district 140b.By this, the outward appearance of upper caldding layer 14 can show shape and the position of press section 142 by the marker space of depression, and the keycap 122 of corresponding button 12 is all distinguished in the actual area in press section 142 and position.
In producing lug step, two embodiments can be comprised again.In a first embodiment, optic-solidified adhesive is clicked and entered in Mang Xian district 140b by manufacturer utilisation point glue machine (not shown), re-uses solidification illumination and penetrates optic-solidified adhesive, it can be made to be attached in Mang Xian district 140b and be solidified into required projection 144.In a second embodiment, manufacturer can utilize 3D printing technique to print every one deck optic-solidified adhesive to add solidification light simultaneously, can obtain required projection 144 equally after being printed to predetermined altitude.It can thus be appreciated that projection 144 of the present utility model is photo cured structural.
Please refer to Fig. 4, illustrate, in the present embodiment, projection 144 has the first height H 1 relative to hot-forming portion 140.Press section 142 has the second height H 2 relative to hot-forming portion 140.First height H 1 is greater than the second height H 2.By this, compared to the blind wire casing of known depression, the projection 144 that the utility model protrudes from surface, press section 142 can, when the finger of user is placed on press section 142, allow user obviously touch projection 144, and then can reach the object of convenient finger location.
In the present embodiment, the second height H 2 that the first height H 1 of projection 144 is greater than press section 142 reaches 0.25 centimetre to 0.4 centimetre.Be noted that, for adopt above-mentioned producing lug step the first embodiment (namely utilizing point gum machine to click and enter) made by projection 144, if the second height H 2 that the optic-solidified adhesive clicking and entering Mang Xian district 140b is less than press section 142 relative to the height in hot-forming portion 140 reaches 0.25 centimetre, the projection 144 then obtained after solidification protrudes not, and user cannot be allowed to feel significantly; If the second height H 2 that the optic-solidified adhesive clicking and entering Mang Xian district 140b is greater than press section 142 relative to the height in hot-forming portion 140 reaches 0.4 centimetre, then may flow out outside Mang Xian district 140b to outdiffusion.
In addition, for adopt above-mentioned producing lug step the second embodiment (namely utilizing 3D printing technique) made by projection 144, although the processing procedure restriction that the first embodiment that there is no producing lug step meets with, if but be printed to the second height H 2 that projection 144 that Mang Xian district 140b formed is greater than press section 142 relative to the height in hot-forming portion 140 and reach 0.4 centimetre, then projection 144 too protrudes from press section 142 again, can affect the finger allodynia of user on the contrary.
It can thus be appreciated that, present embodiment is for the limitation in height of projection 144, not only can overcome the processing procedure defect of the first embodiment of above-mentioned producing lug step, also can make projection 144 can obviously by doigte to and play its function for finger location, and projection 144 can be avoided too to protrude and affect the finger allodynia of user.
In the present embodiment, upper caldding layer 14 and lower caldding layer 16 are all polyurethane (PolyUrethane, PU) leather layer, but the utility model is not as limit.In actual applications, upper caldding layer 14 and lower caldding layer 16 also can be made by unlike material.
By the detailed description above for the specific embodiment of the utility model, can find out significantly, keyboard of the present utility model forms projection further in tectal Mang Xian district, and this projection is relative to the height in hot-forming portion, is greater than the height of press section relative to hot-forming portion.By this, when the finger of user is placed on press section, obviously can touches pressed portion and surround and the projection protruded, and then the function of convenient finger location can be reached.
Although the utility model discloses as above with execution mode; so itself and be not used to limit the utility model; anyly have the knack of this those skilled in the art; not departing from the spirit and scope of the utility model; when various changes and retouching can be done, therefore the utility model protection range when depending on after the attached claim person of defining be as the criterion.
