Embodiment
Below in conjunction with drawings and Examples elastic press type button of the present invention is further specified.
Elastic press type button of the present invention can be used for computer keyboard, the keyboard of notebook computer especially, but be not limited to such use.Please shown in Figure 2 in conjunction with consulting, Fig. 2 is the perspective exploded view of elastic press type button first preferred embodiment of the present invention, and in this preferred embodiment, elastic press type button 100 comprises key frame 1, keycap 2, two elastic arms 3, elastomer 4, conductive film 5 and base plate 6.
Please in conjunction with Fig. 2 and shown in Figure 6, the partial structurtes schematic diagram when Fig. 6 is not pressed for elastic press type button 100, key frame 1 is for having certain thickness cubic frame structure, and its central authorities have the square containing hole 12 of perforation upper and lower surface, are used to hold chimeric keycap 2.The back-shaped groove 14 that non-through key frame 1 top is arranged is also expanded along the periphery of containing hole 12 in the bottom of key frame 1, thereby forms cell wall 142 at the back side, key frame 1 top.
Shown in Fig. 3 and 4, Fig. 3 is the keycap of elastic press type button 100 and the structural representation after the elastic arm combination, Fig. 4 is another visual angle structural representation of Fig. 3, keycap 2 is block for the four directions with certain thickness and symmetrical configuration, have four external angles 201 (referring to Fig. 2), it offers square groove 22 in bottom center keycap 2, and groove 22 central authorities are formed with M shape projection 24.Keycap 2 bottoms have first limit 202, second limit 204, three limit 206 adjacent, and four limit 208 relative with first limit 202 with first limit 202, and wherein, each is identical to relative edge's length.The bottom of keycap 2 is being formed with the central authorities that are positioned at corresponding sides and the positioning convex column 26,27 at two ends respectively near first limit 202 and 208 places, the 4th limit.
Please again in conjunction with Fig. 2 and shown in Figure 4, elastic arm 3 is flat rib-like.It comprises internal fixation arm 32, be positioned at internal fixation arm 32 both sides and with the vertical outer movable arm 34 of internal fixation arm 32, be connected two angle transition parts 36 of internal fixation arm 32 and outer movable arm 34.Wherein, the median vertical line symmetry of elastic arm 3 relative internal fixation arms 32, and the distance of 34 of the outer movable arms of internal fixation arm 32 both sides is slightly larger than the length with first limit 202 or the 4th limit 208, and certainly, the distance that two outer movable arms are 34 also can be bigger.The internal fixation arm 32 of two elastic arms 3 is respectively equipped with at central authorities and two ends and is provided with location hole 322,324, is used for being inserted in respectively first limit 202 of being located at keycap 2 and positioning convex column 26,27 location of the 4th limit 208 correspondences.The end of two outer movable arms 34 offers connecting hole 342.
Please be extremely shown in Figure 6 in conjunction with Fig. 3 simultaneously, when needs are assembled elastic arm 3 with key frame 1 and keycap 2, at first will be wherein the central authorities of the internal fixation arm 32 of an elastic arm 3 and the location hole 322 at two ends, 324 correspondences are inserted in the positioning convex column 26 of first limit, 202 correspondences of keycap 2 bottoms, on 27, thereby internal fixation arm 32 is positioned on the inboard, edge on first limit 202 of keycap 2 bottoms, and the outer movable arm 34 of internal fixation arm 32 both sides is exposed to outside second limit 204 and 206 edges, the 3rd limit, in like manner, the internal fixation arm 32 of another elastic arm 3 is positioned on the inboard, edge on the 4th limit 208 of keycap 2 bottoms, and the outer movable arm 34 of internal fixation arm 32 both sides exposes outside second limit 204 adjacent with the 4th limit 202 and 206 edges, the 3rd limit (as shown in Figure 5), wherein, be close to be separated by in end (certainly, also can be arranged to make it to assemble this two outer movable arm 34 then just do not overlap) at regular intervals with on one side two outer movable arms 34.Subsequently, keycap is fitted to from lower to upper in the containing hole 12 of key frame 1, the end of each the outer movable arm 34 on second limit 204 and the 3rd limit 206 is fixed on by connecting hole 342 on the cell wall 142 at the back side, top of key frame 1.
Please consult shown in Figure 2 again, elastomer 4 is the rubber pressing body, and elastomer 4 bottoms are fixed on the conductive film 5, and the top has an open slot 42, the M shape projection 24 of keycap 2 stretches in this open slot 42, thereby makes elastomer 4 held stationary on keycap 2 and conductive film 5.Certainly, the bottom of elastomer 4 also can be positioned on the conductive film 5.Base plate 6 is located at conductive film 5 belows, key frame 1 and base plate 6 relative fixed.
Please consult shown in Figure 6 again, when keycap 2 is not pressed, the outer movable arm 34 and the angle transition part 36 of elastic arm 3 all do not deform, as shown in Figure 7, when keycap 2 is pressed, keycap 2 compressing elastic arms 3 move downward with the joining A at keycap 2 edges, thereby make the outer movable arm 34 and the angle transition part 36 of elastic arm 3 that strain all take place, and four angles that make keycap 2 are extruded spacingly in four angle transition parts 36 respectively, and at this moment, four angle transition parts 36 change into vertical keycap 2 directions with pressing force, can not cause pushing the deflection situation, simultaneously, elastomer 4 is pressed down, and contacts with conductive film 5.So can make conductive film 5 produce electronic signal, so that the function of button to be provided.After keycap 2 was released, elastic arm 3 and elastomer 4 provided an elastic-restoring force, make keycap 2 return back to original position.
Above-mentioned elastic press type button 100 designs four jiaos of strong points in the rib mode, be that stretch out toward the adjacent edges with this limit on one side and along its corresponding external angle 201 bottom that each angle transition part 36 of elastic arm 3 stretches out keycap 2, on each angle of button, all be formed with the strong point by bar shaped elastic arm 3, and the support force at each angle size is consistent, change into power comparatively stably in the time of can being convenient to press down keycap 2, and can make pressing force be delivered to the button center easily, make pressing force be difficult for taking place deflection, push more accurately and put in place, feel is also better; In addition, elastic press type button 100 adopts two identical elastic arms 3 to replace the scissor supporting structure of prior art, and the part of employing is less, and structure is comparatively simple, simple and convenient assembly, and part and die sinking cost are also lower; And elastic arm 3 thickness are less, help the reductionization of button thickness.
Be appreciated that, also can elastic arm 3 be disconnected in internal fixation arm 32 central authorities, as shown in Figure 8, it has shown the resilient arm structure schematic diagram of elastic press type button second preferred embodiment of the present invention, this moment, elastic arm 3a had an internal fixation arm 32a, one perpendicular outer movable arm 34a, an and angle transition part 36a who connects this internal fixation arm 32a and outer movable arm 34a, wherein, internal fixation arm 32a locatees or is fixed on one side of keycap 2 bottoms, and this angle transition is stretched out with adjacent edge by the external angle of this edge correspondence is past equally, at this moment, the quantity of elastic arm 3a can be according to the external angle quantity correspondence of keycap 2.
The above is preferred embodiment of the present invention only, is not in order to limiting practical range of the present invention, and therefore all other do not break away from the equivalence of being finished under the disclosed spirit and change or modify, and all should be included in protection scope of the present invention.
