Below in conjunction with the drawings and specific embodiments, describe the present invention, but not as a limitation of the invention.
Referring to Fig. 2, Fig. 3 and Fig. 4, Fig. 2 is press-key structure schematic diagram of the present invention, Fig. 3 is the structural representation in the partial structurtes front of key assembling of the present invention on handset shell, and Fig. 4 is the structural representation at the partial structurtes back side of key assembling of the present invention on handset shell.
As shown in Figure 2, Figure 3 and Figure 4, the invention provides a kind of button 20, it can be applicable to electronic installation, above-mentioned electronic installation is for example mobile phone, individual digital computer (PAD), audio player or video player, and in present embodiment, be to describe as an example of mobile phone example, but the present invention is not as limit.
Continue referring to Fig. 2 and Fig. 3, in the present embodiment, for trigger element 25 is not contacted with switch element 32 in the situation that user does not apply external force, the two ends of elastic body 21 are respectively arranged with locating convex block 27 and locating convex block 28, wherein, locating convex block 27 and locating convex block 28 lay respectively at the both sides of trigger element 25, locating convex block 27 and the side of locating convex block 28 against circuit board 31 vicinities and relative trigger element 25, to avoid, between trigger element 25 and switch element 32, unnecessary contacting occurs, and cause mobile phone to carry out the unwanted operation of user.In above-described embodiment, to be bent respectively to form locating convex block 27 and locating convex block 28 at the two ends of elastic body 21, in other embodiments of the invention, the quantity of locating convex block also can be 1,3 or more, that is the setting position of locating convex block, quantity and shape can be adjusted according to actual needs.
In the above embodiment of the present invention, be the button touch feeling obtaining, elastic body 21 can be formed in one with draw-in groove 23.And in other embodiments of the invention, draw-in groove 23 is provided with fixing projection, elastic body 21 is provided with the groove matching with fixing projection, by the cooperation of projection and groove, make that draw-in groove 23 is dismountable to be assembled on elastic body 21, and be installed on elastic body 21 because draw-in groove 23 is dismountable, it is suitable that the first accommodation space 24 on draw-in groove 23 can have the switch element 32 of difformity on sizes and shape and circuit board 31 or size, to reach the object that makes button 20 be suitable for different electronic installations.
In the above embodiment of the present invention, elastic body 21 need to provide suitable flexible motion to drive trigger element 25 contact-making switch elements 32, therefore, the material of elastic body 21 is preferably silica gel, rubber or polyurethane resin etc. and has suitable rigidity and flexible material.
In the above embodiment of the present invention, keycap 22 can be the keycap of metal or plastics.
Please refer to Fig. 5, Fig. 5 is the schematic diagram of the electronic installation that comprises button of the present invention, as shown in Figure 5, electronic installation 40 comprises housing 41, on housing 41, have perforate 42, housing 41 is in order to accommodating the present invention button 20 as above and circuit board 31, wherein, keycap 22 can be given prominence to housing 41 in perforate 42, and above-mentioned housing 41 is for example formed by fore shell and back cover assembling.In the present embodiment, take mobile phone as electronic installation as example describes, but not as limit, in other embodiments of the invention, electronic installation is mobile phone, individual digital computer (PAD), audio frequency or video player etc.
As an example of the electronic installation 40 shown in Fig. 5 example, how explanation above-mentioned button 20 of the present invention effectively avoids assembling tolerance.First, by button 20 with circuit board 31 to group, make circuit board 31 enter draw-in groove 23, switch element 32 embeds the first accommodation space 24 and trigger element 25 is relative with the element 32 that opens the light, plate body structure 26 support circuit plates 31; Secondly, the button 20 after group is assembled in housing 41 with circuit board 31 simultaneously, and makes keycap 22 outstanding in the perforate 42 of housing 41.Button 20 provided by the invention, owing to first carrying out stablely to group with circuit board 31, can guarantee that user is when pressing elastic body 21, makes the accurate trigger switch element 32 of trigger element 25.Therefore, the method of assembling compared to the assembling tolerance that must strictly meet side button and circuit board in prior art, adopt above-mentioned button provided by the invention, by the setting of draw-in groove 23 and the first accommodation space 24, can more simple and effectively make button 20 be assembled on circuit board 31, and in assembling process, the demand of assembling tolerance between button 20 and circuit board 31 is significantly reduced, and significantly improved the accuracy rate of key assembling.
In addition, in the various element assemblings of electronic installation, all need to retain default assembling tolerance, take the electronic installation 40 in Fig. 5 as example, but not as limit, due to the normal surface that adopts the mode of welding to be fixed on circuit board 31 of switch element 32, and for switch element 32 is fixed on circuit board 31 more reliably, reference column (not shown) is set conventionally on switch element 32, on circuit board 31, corresponding to reference column, location hole (not shown) is set, wherein, the diameter of reference column is for example 0.2mm, the diameter of location hole is for example 0.5mm, therefore, switch element 32 is 0.15mm with the maximum assembling tolerance of circuit board 31, assembling tolerance 0.15mm based on above-mentioned maximum, spacing between perforate 42 and keycap 22 on housing 41 need be greater than maximum assembling tolerance 0.15mm to meet assembling needs.
To sum up, button provided by the invention and use its electronic installation to illustrate in above-described embodiment, button of the present invention compared with prior art, by the draw-in groove clamping circuit board of elastic body on button, and the switch element on circuit board is directly sheathed on the first accommodation space communicating with draw-in groove, button, circuit board and housing number of assembling steps have been simplified, due to, directly button is sheathed on circuit board, therefore, effectively improve assembly precision, avoided because of assembling tolerance cause the not good problem of button touch feeling.
Certainly; the present invention also can have other various embodiments; in the situation that not deviating from spirit of the present invention and essence thereof; those of ordinary skill in the art can make according to the present invention various corresponding changes and distortion, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
