Embodiment
Describe the present invention below in conjunction with the drawings and specific embodiments, but not as a limitation of the invention.
Refer to Fig. 1 and Fig. 2, Fig. 1 is the schematic diagram of the keyboard of the embodiment of the present invention, and Fig. 2 is the assembly explosive view of the button of the embodiment of the present invention.Keyboard 10 can comprise a plurality of button 12 simultaneously, and the base plate 14 of keyboard 10 has a plurality of position limiting structure 16, and each button 12 is arranged on corresponding position limiting structure 16.Further, as shown in Figure 2, button 12 comprises keycap 18, balancing pole 20, lamellar body 22, elastomeric pad 24, lifting supporting mechanism 26 and elastomer 28.Lamellar body 22 has noise abatement portion 30.Two end limits 201 of balancing pole 20 utilize position limiting structure 16 to be arranged on base plate 14 in a rotatable manner, and the centre portion 202 of balancing pole 20 connects keycap 18 with snap fit, allows keycap 18 be arranged on movably on base plate 14 through balancing pole 20.Lifting supporting mechanism 26 is selectivity assembly with elastomer 28, is all arranged between keycap 18 and base plate 14, is used to provide support force and operating handle to button 12.
Lamellar body 22 is soft materials composition, such as, be made by polyester film (Mylar), be used for covering the metallic member between button 18, seem more attractive in appearance to allow keyboard appearance.Normally a kind of button hole structure of position limiting structure 16, this button hole structure is inserted to provide the degree of freedom that can relatively rotate in the end limit 201 of balancing pole 20, so the body of rod size of balancing pole 20 will inevitably be slightly less than the aperture size of position limiting structure 16, is convenient to both and combines; But when operation push-button 12, balancing pole 20 can collide the inwall of position limiting structure 16 every now and then and make a noise.Therefore, the noise abatement portion 30 that lamellar body 22 extends by the present invention is adjacent to the other and support of position limiting structure 16 below balancing pole 20.Noise abatement portion 30 can slightly lifting balancing pole 20, reduces the gap of balancing pole 20 and position limiting structure 16 inwall, makes balancing pole 20 closely attach the inwall of position limiting structure 16 as far as possible, to avoid producing collision sound.
Refer to Fig. 3 to Fig. 5, Fig. 3 and Fig. 4 is respectively the part-structure schematic diagram of button in different visual angles of the embodiment of the present invention, and Fig. 5 is for button shown in Fig. 2 is along the schematic cross-section of hatching A-A '.As can be seen from Fig. 3 and Fig. 4, noise abatement portion 30 is the blocks part of support balancing pole 20 (be used for) near position limiting structure 16, and balancing pole 20 can hold in the palm high with the inwall pasting neat position limiting structure 16 by noise abatement portion 30.But, can space be formed between noise abatement portion 30 and base plate 14.When the weight of balancing pole 20 exceeds the support ability of lamellar body 22, the noise abatement portion 30 meeting pressurized of lamellar body 22 is sagging and near base plate 14, be difficult to provide enough supporting force lifting balancing poles 20.Therefore, the present invention arranges elastomeric pad 24 in the below in noise abatement portion 30, elastomeric pad 24 has filled up the space between noise abatement portion 30 and base plate 14, support force upwards can be provided to noise abatement portion 30, the overall supporting force of strengthening lamellar body 22, make balancing pole 20 can the inwall of substantial exposure position limiting structure 16, collision free makes a noise.
As shown in Figures 2 to 5, because noise abatement portion 30 is positioned at the edge of lamellar body 22, and form space below noise abatement portion 30 and between base plate 14, noise abatement portion 30 can be considered the free end of lamellar body 22, and namely elastomeric pad 24 is arranged on the below of the free end of lamellar body 22; Certainly, elastomeric pad 24 also can be arranged on the below of the free end in noise abatement portion 30.In addition, the noise abatement portion 30 of lamellar body 22 misplaces in position limiting structure 16 with the bridge section 203 of support balancing pole 20, namely noise abatement portion 30 neither be arranged on position limiting structure 16 aperture by, below the aperture that neither be arranged on position limiting structure 16.In embodiments of the present invention, elastomeric pad 24 is generally the individual member that can be separated with base plate 14, such as foam, sponge, rubber mount, elastic gel, polyester film etc.; Certainly, elastomeric pad 24 also can be incorporated into base plate 14 in the mode of ejection formation.The form of elastomeric pad 24 is not construed as limiting, and determines according to actual conditions, and the free end that only need meet support lamellar body 22 can lifting balancing pole 20.
In sum, the lamellar body 22 of button 12 utilizes the noise abatement portion 30 support balancing pole 20 of free end.Owing to there is space between noise abatement portion 30 and below base plate 14, depend merely on the more difficult strength lifting balancing pole 20 that stable abundance is provided in noise abatement portion 30, therefore the present invention also arranges elastomeric pad 24 in the below in noise abatement portion 30, increase thickness to plug the gap, allow balancing pole 20 can through noise abatement portion 30 inwall with the elasticity recovery characteristics close contact position limiting structure 16 of elastomeric pad 24.So, user is when operation push-button 12, and balancing pole 20 just can not collide inwall and produce noise by bob in position limiting structure 16.
The height of noise abatement portion 30 and elastomeric pad 24 and preferably need the difference being greater than the aperture size of position limiting structure 16 and the body of rod size of balancing pole 20.Because noise abatement portion 30 and elastomeric pad 24 are all that soft materials forms, so such height design does not have interference problem, gap between position limiting structure 16 and balancing pole 20 can be filled up completely on the contrary through the natural resiliency deflection of noise abatement portion 30 and elastomeric pad 24, also balancing pole 20 can not be hindered to insert the assembling fluency of position limiting structure 16, certainly more can not limiting balance bar 20 rotation and affect operating handle.
So compared to prior art, button of the present invention utilizes the setting of elastomeric pad effectively can solve the noise problem of conventional keys when operating, and has the advantage that assembling is simple, material cost is cheap, integrated operation is smooth concurrently.
Certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection range that all should belong to the claim appended by the present invention.
