Description
[technical field]
The present invention relates to the key lifting switch device of keyboard, relate in particular to key lifting switch device, also relate to the automatic assemble method of the corresponding button of a key lifting switch device therewith as the ultrathin button in the keyboard of the input unit of electronic instrument.
[background technology]
Tw Taiwan applicant Jingyuan Computer Co., Ltd is at theme as " the ultrathin keyboard " of China's application, and in bulletin on March 1st, 2000, notification number is CN2366889Y.This patent has been represented the main flow structure of early stage ultrathin keyboard, is widely used in the keyboard of various notebook computers, is subjected to certain welcome.Its structure sees also the specification of this part bulletin, mainly comprises keycap, location-plate, first framework, second framework, elastomer, film circuit board and base plate, forms a pivot portion, guide runner, press section and several pieces positioning baffles on the keycap bottom surface; Hollow out forms guide runner and axle pivot portion on the location-plate; With first framework and second framework is scissor supporting construction, and articulates and to be assembled between keycap axle pivot portion and the location-plate axle pivot portion, and elastomer places press section, keycap bottom surface to locate, and film circuit board is between elastomer and base plate.Thus, follow finger presses and release power elastomeric time, keycap is lifting thereupon, and in the process of lifting, realize keycap steadily evenly descending by first framework of scissor supporting construction and the slip of the guide runner of second framework on keycap and location-plate with respect to location-plate, release power by elastomeric time simultaneously and steadily evenly rising, the structure that wherein plays a significant role just is this scissor structure.
On the packaging technology that the deficiency of the maximum of this structure of CN2366889Y is to bring thus, the assembling of the assembling between its first framework and second framework, first framework and second framework and keycap and location-plate, and integrally-built assembling etc., owing to there be cooperating of a plurality of micro hole position and pivot, cause being not easy to realize streamlined production, thereby influence production efficiency.Even wherein the easy-to-assemble link of part realizes mechanization, also be very easy to product qualified rate is significantly reduced.
On the other hand, first framework and second framework must be separated mutually when injection mo(u)lding, and the form that forms after injection moulding with craft or tool reconfigures in pairs, thereby have also increased assembly cost.
And then; applicant Fujitsu Component Ltd. has proposed new technical scheme as the industry peer; see disclosed CN1716483A patent announcement on January 4th, 2006 for details; it protects a kind of key switch; clearly make the improvement of research and development property at the monopolization of aforementioned patent; disclose to adopt and a pair ofly to be reverse V-shaped pair of links parts and to replace aforementioned scissor structure; it is one of any that concrete difference is to constitute two assemblies of V-type linkage component; one end can slide on location-plate, and the other end is meshed with tooth each other and all is hubbed on the keycap bottom surface.Because the meshing relation of linkage component, but make whole linkage component make the time spent synchronous on-off and realize sliding in the chute at location-plate, thereby further drive keycap steadily lifting equably in vertical direction stressed.
It should be noted that, linkage component one speech of " interlock supports the pair of links parts at described key top with direction lifting direction guiding on described support plate mutually " addressed in the CN1716483A patent announcement, the scissor structure of also having summarized the CN2366889Y patent announcement with the form of upperization: linkage component must have a pair of totally two assemblies, and two assemblies interconnect motion.So just qualification has caused the technical scheme of these two parts of patents that the present invention quotes all can't overcome the defective of assembling process.The defective of CN2366889Y is in preceding analysis, and the defective of CN1716483A also is tangible, except the inconvenience of the installation of sliding end on location-plate of linkage component, in the assembling of the prior toothed engagement relation that also is linkage component, often be difficult to ideally cooperatively interact, thereby cause product qualified rate lower.
In addition, the linkage component of CN1716483A patent announcement is difficult for so that the engagement shape injection mo(u)lding of time spent, and must be present in the mode of separating a segment distance in the middle of the injection mold, and after the injection mo(u)lding by hand mode re-position between location-plate and the keycap, or with tool formula assembling mode, the linkage component of separating injection molded is reconfigured installation, be difficult to control the precision and the human cost of assembling.
Moreover, the above-mentioned two parts of linkage component that engagement capability is arranged or scissor frameworks that bulletin is put down in writing, owing to still need by hand after the injection mo(u)lding or tool reconfigures installation, and because the miniaturization of keyboard and the requirement of ultra-thinization, make above-mentioned linkage component or framework miniaturization day by day, so the precision of tool is difficult for realizing.
Yet, nowadays relevant patent with above-mentioned two patent announcement representatives is present in the patent database of every country in the world in a large number, sequitur this area research staff's inertial thinking all is to set out based on " linkage component ", fail to walk out this set thinking for many years, on the other hand, because painstakingly upperization of each patent and patentee both got Patent right, the research and development thinking that has further limited the research staff again can't freely be circled in the air.Thus, at least during a nearly age, the applicant thinks, key lifting switch device is the leap on the acquisition of technology not.
But this leap is needed in white-hot competition badly between development of science and technology trend and market.The applicant is engaged in this area research and development for many years, in line with the conviction that all roads lead to Rome, at the beginning of research and development, just thinking is independent of outside aforementioned " linkage component ", be devoted to probe into always and a kind ofly overcome with above-mentioned two parts of patent announcements new departure by the intrinsic deficiency of the various technical schemes of representative, now reach target, and finally on producing, put into practice demonstration.
