除此之外，按键34包含有升降支撑机构40，其设置于底板30与键帽36之间。当使用者按压按键34时，升降支撑机构40可将使用者的按压力平均分配给键帽36，以使键帽36可平稳地相对底板30向下运动，藉以稳定地触发开关321而执行该按键指令。当键帽36于上述的复位过程中，升降支撑机构40可将弹性件38所产生的该弹性回复力平均分配给键帽36，以使键帽36可平稳地相对底板30向上运动。换句话说，升降支撑机构40可用来带动键帽36平稳地相对底板30升降，以使键帽36于升降过程中保持平稳，有助于按键34作动的稳定度。In addition, thekey 34 includes alifting support mechanism 40 disposed between thebottom plate 30 and thekeycap 36 . When the user presses thebutton 34, thelifting support mechanism 40 can evenly distribute the pressing force of the user to thekeycap 36, so that thekeycap 36 can move downwards smoothly relative to thebottom plate 30, thereby stably triggering theswitch 321 to perform the operation. Key commands. When thekeycap 36 is in the above reset process, thelifting support mechanism 40 can evenly distribute the elastic restoring force generated by theelastic member 38 to thekeycap 36 so that thekeycap 36 can move upward relative to thebottom plate 30 smoothly. In other words, thelifting support mechanism 40 can be used to drive thekeycap 36 to move up and down smoothly relative to thebottom plate 30 , so that thekeycap 36 can be kept stable during the lifting process, which is helpful for the stability of thekey 34 .

如图2至图5所示，按键34另包含有至少一连接杆件42以及两卡扣端板44。连接杆件42用来连接键帽36与底板30，且卡扣端板44连接于底板30。请参阅图3至图7，图6为本发明实施例按键34于另一视角的元件示意图，图7为本发明实施例卡扣端板44与底板30的元件部分示意图。如图3至图7所示，卡扣端板44上形成有至少一滑槽441，按键34另包含有复数个枢接结构46，其设置于键帽36上，且复数个枢接结构46用来将键帽36枢接于各连接杆件42的一侧边部421。于组装连接杆件42时，可将各连接杆件42的一端部423可滑动地卡扣于对应的滑槽441内，且另将各连接杆件42的侧边部421枢接于对应的枢接结构46。As shown in FIGS. 2 to 5 , thebutton 34 further includes at least one connectingrod 42 and twolocking end plates 44 . The connectingrod 42 is used to connect thekeycap 36 and thebottom plate 30 , and thebuckle end plate 44 is connected to thebottom plate 30 . Please refer to FIG. 3 to FIG. 7 . FIG. 6 is a schematic diagram of components of thebutton 34 in another view according to the embodiment of the present invention, and FIG. 7 is a schematic diagram of components of thebuckle end plate 44 and thebottom plate 30 according to the embodiment of the present invention. As shown in FIGS. 3 to 7 , at least onechute 441 is formed on thebuckle end plate 44 , and thebutton 34 further includes a plurality ofpivot structures 46 , which are arranged on thekeycap 36 , and the plurality ofpivot structures 46 Theside portion 421 is used to pivotally connect thekeycap 36 to each connectingrod 42 . When assembling the connectingrods 42, oneend 423 of each connectingrod 42 can be slidably buckled in thecorresponding slide groove 441, and theside portion 421 of each connectingrod 42 is pivotally connected to thecorresponding Pivot structure 46.

于此实施例中，按键34可包含有两个连接杆件42，且各卡扣端板44上可形成有两个滑槽441，各连接杆件42的侧边部421及端部423分别安装于对应的枢接结构46及滑槽441内，而连接杆件42及各卡扣端板44上的滑槽441数量可不局限于此实施例图式所绘示，例如按键34亦可仅包含有一个连接杆件42，且各卡扣端板44上亦可对应地仅形成有一个滑槽441。换句话说，只要是按键34包含有一个以上的连接杆件42以及卡扣端板44上形成有一个以上的滑槽441的结构设计，均在本发明所保护的范畴内。In this embodiment, thebutton 34 can include two connectingrods 42, and eachbuckle end plate 44 can be formed with twoslide grooves 441, and theside portion 421 and theend 423 of each connectingrod 42 are respectively Installed in thecorresponding pivot structure 46 andslide groove 441, and the number ofslide grooves 441 on the connectingrod 42 and eachbuckle end plate 44 is not limited to that shown in the drawing of this embodiment, for example, thebutton 34 can also be only One connectingrod 42 is included, and only oneslide slot 441 can be formed on eachbuckle end plate 44 correspondingly. In other words, as long as thebutton 34 includes more than one connectingrod 42 and thebuckle end plate 44 has more than one slidingslot 441 , it is within the scope of protection of the present invention.

如图5所示，当键帽36被按压时，两连接杆件42的端部423可朝彼此靠近的方向相对滑槽441滑动，且两连接杆件42的侧边部421可于对应的枢接结构46内枢转，此时键帽36便可被两连接杆件42的侧边部421带动而接近底板30。此外，当使用者按压按键34时，两连接杆件42可与升降支撑机构40共同将使用者的按压力平均分配给键帽36，以使键帽36可更平稳地相对底板30向下运动，藉以稳定地触发电路板32的开关321而执行该按键指令。As shown in FIG. 5 , when thekeycap 36 is pressed, theends 423 of the two connectingrods 42 can slide relative to the slidinggroove 441 toward each other, and theside portions 421 of the two connectingrods 42 can be aligned with the corresponding The pivotingstructure 46 pivots inwardly, and at this moment, thekeycap 36 can be driven by theside portions 421 of the two connectingrods 42 to approach thebottom plate 30 . In addition, when the user presses thebutton 34, the two connectingrods 42 and thelifting support mechanism 40 can evenly distribute the pressing force of the user to thekeycap 36, so that thekeycap 36 can move downward relative to thebottom plate 30 more smoothly. , so as to stably trigger theswitch 321 of thecircuit board 32 to execute the key command.

同理，当键帽36被释放时，弹性件38释放该弹性位能而施予键帽36该弹性回复力，藉以驱动键帽36复位。当键帽36于上述的复位过程中，两连接杆件42的端部423可朝彼此远离的方向相对滑槽441滑动，且两连接杆件42的侧边部421可于对应的枢接结构46内枢转，此时键帽36便可被两连接杆件42的侧边部421带动而远离底板30。此外，当键帽36于上述的复位过程中，两连接杆件42可与升降支撑机构40共同将弹性件38所产生的该弹性回复力平均分配给键帽36，以使键帽36可平稳地相对底板30向上运动。换句话说，连接杆件42亦可用来驱动键帽36平稳地接近或远离底板30，以使键帽36于升降过程中保持平稳，有利于按键34作动时的稳定度。Similarly, when thekeycap 36 is released, theelastic member 38 releases the elastic potential energy and imparts the elastic restoring force to thekeycap 36 , thereby driving thekeycap 36 to reset. When thekeycap 36 is in the above-mentioned reset process, theends 423 of the two connectingrods 42 can slide relative to theslide groove 441 in the direction away from each other, and theside parts 421 of the two connectingrods 42 can be aligned with the corresponding pivot structure. 46 , thekeycap 36 can be driven by theside portions 421 of the two connectingrods 42 to move away from thebottom plate 30 . In addition, when thekeycap 36 is in the above-mentioned reset process, the two connectingrods 42 can work together with the liftingsupport mechanism 40 to evenly distribute the elastic restoring force generated by theelastic member 38 to thekeycap 36, so that thekeycap 36 can be stabilized. The ground moves upward relative to thebottom plate 30 . In other words, the connectingrod 42 can also be used to drive thekeycap 36 to approach or move away from thebottom plate 30 stably, so that thekeycap 36 remains stable during the lifting process, which is beneficial to the stability of thebutton 34 when it is actuated.

如图3、图6以及图7所示，卡扣端板44包含有卡扣板体443以及连接板体445，连接板体445连接于卡扣板体443的一侧与底板30的一边缘。于此实施例中，卡扣板体443可实质上垂直于连接板体445，且滑槽441形成于卡扣板体443与连接板体445上。此外，卡扣端板44可另包含有延伸板体447，其延伸于卡扣板体443的另一侧。于此实施例中，延伸板体447可实质上垂直于卡扣板体443，亦即延伸板体447可平行于连接板体445。于实际应用上，卡扣板体443、连接板体445以及延伸板体447可以冲压成型的方式一体成型。值得一提的是，延伸板体447为一可省略的结构，亦即本发明的卡扣端板44可仅包含有卡扣板体443与连接板体445而不包含有延伸板体447，藉以简化卡扣端板44的制造过程。As shown in FIG. 3 , FIG. 6 and FIG. 7 , thebuckle end plate 44 includes abuckle plate body 443 and a connectingplate body 445 , and the connectingplate body 445 is connected to one side of thebuckle plate body 443 and an edge of thebottom plate 30 . In this embodiment, the lockingplate 443 can be substantially perpendicular to the connectingplate 445 , and theslide groove 441 is formed on thelocking plate 443 and the connectingplate 445 . In addition, the lockingend plate 44 may further include anextension plate body 447 extending from the other side of the lockingplate body 443 . In this embodiment, theextension plate 447 can be substantially perpendicular to thelocking plate 443 , that is, theextension plate 447 can be parallel to theconnection plate 445 . In practical applications, the lockingplate 443 , the connectingplate 445 and the extendingplate 447 can be integrally formed by stamping. It is worth mentioning that theextension plate 447 is an omissible structure, that is, thebuckle end plate 44 of the present invention may only include thebuckle plate 443 and the connectingplate 445 without theextension plate 447, In this way, the manufacturing process of thebuckle end plate 44 is simplified.

除此之外，按键34另包含有承载凹部48，其形成于底板30上，且承载凹部48邻接于卡扣板体443与连接板体445上的滑槽441。另外，承载凹部48的承载面481与底板30的顶面301相距一断差S（如图6以及图7所示），因此当连接杆件42的端部423可滑动地卡扣于卡扣板体443与连接板体445上的滑槽441内时，连接杆件42的端部423陷入承载凹部48内且承靠于承载凹部48的承载面481。如此一来，承载凹部48的承载面481便可与卡扣端板44的延伸板体447共同防止连接杆件42的端部423翻转，以使连接杆件42的端部423能稳定地于滑槽441内滑动。In addition, thebutton 34 further includes a bearingrecess 48 formed on thebase plate 30 , and the bearingrecess 48 is adjacent to theslide groove 441 on thelocking plate 443 and the connectingplate 445 . In addition, the bearingsurface 481 of the bearingrecess 48 is separated from thetop surface 301 of thebottom plate 30 by a step S (as shown in FIG. 6 and FIG. 7 ), so when theend 423 of the connectingrod 42 is slidably locked in When theplate body 443 is connected to theslide groove 441 on theplate body 445 , theend portion 423 of the connectingrod 42 sinks into the carryingrecess 48 and leans against the carryingsurface 481 of the carryingrecess 48 . In this way, the bearingsurface 481 of the bearingrecess 48 can work with theextension plate body 447 of thebuckle end plate 44 to prevent theend 423 of the connectingrod 42 from turning over, so that theend 423 of the connectingrod 42 can be stably placed on the Slide in thechute 441.

进一步地，由于承载凹部48的承载面481与底板30的顶面301相距断差S，当连接杆件42的端部423陷入承载凹部48内且承靠于承载凹部48的承载面481时，连接杆件42便可自底板30的顶面301下降断差S。也就是说，于连接杆件42的端部423组装至卡扣端板44后，连接杆件42的端部423因陷入底板30上的承载凹部48而使连接杆件42的侧边部421朝底板30靠近约断差S的距离，而连接杆件42的侧边部421枢接于键帽36上的枢接结构46，故键帽36亦可被连接杆件42的侧边部421带动而朝底板30靠近约断差S的距离，如此按键34的整体高度便可下降，进而有利于按键34及键盘3朝向薄型化发展的趋势。Furthermore, since the bearingsurface 481 of the bearingrecess 48 is separated from thetop surface 301 of thebottom plate 30 by a gap S, when theend 423 of the connectingrod 42 sinks into the bearingrecess 48 and bears against the bearingsurface 481 of the bearingrecess 48, The connectingrod 42 can descend the step S from thetop surface 301 of thebottom plate 30 . That is to say, after theend 423 of the connectingrod 42 is assembled to thebuckle end plate 44, theend 423 of the connectingrod 42 sinks into the bearingrecess 48 on thebottom plate 30 so that theside portion 421 of the connectingrod 42 Close to thebottom plate 30 by a distance of about the gap S, and theside portion 421 of the connectingrod 42 is pivotally connected to thepivot structure 46 on thekeycap 36, so thekeycap 36 can also be connected to theside portion 421 of therod 42 Driven toward thebottom plate 30 by a distance of about the gap S, the overall height of the key 34 can be reduced, which is conducive to the development trend of the key 34 and the keyboard 3 toward thinning.

于此实施例中，承载凹部48可以冲压成型的方式形成于底板30上，亦即承载凹部48为在底板30上以冲压成型的方式所形成的打凹结构。于实际应用上，承载凹部48的承载面481与底板30的顶面301相距的断差S实质上等于0.1厘米，但不受此限。此外，底板30上形成有开口303，其邻接于承载凹部48，且开口303与滑槽441位于承载凹部48的相对两侧，于底板30以冲压成型的方式形成承载凹部48的过程中，由于底板30受挤压而凹陷形成承载凹部48，故底板30的材料会向旁侧扩溢，而开口303便可用来提供向旁侧扩溢的底板30的材料一溢料空间，以使承载凹部48能顺利地形成于底板30上。In this embodiment, the carryingrecess 48 can be formed on thebottom plate 30 by stamping, that is, the carryingrecess 48 is a recessed structure formed on thebottom plate 30 by stamping. In practice, the gap S between thebearing surface 481 of the bearingrecess 48 and thetop surface 301 of thebottom plate 30 is substantially equal to 0.1 cm, but not limited thereto. In addition, anopening 303 is formed on thebottom plate 30, which is adjacent to the carryingrecess 48, and theopening 303 and the slidinggroove 441 are located on opposite sides of the carryingrecess 48. Thebottom plate 30 is pressed and depressed to form abearing recess 48, so the material of thebottom plate 30 will overflow to the side, and theopening 303 can be used to provide a overflow space for the material of thebottom plate 30 that overflows to the side, so that the carryingrecess 48 can be formed on thebottom plate 30 smoothly.

相较于现有技术，本发明利用形成于底板上的承载凹部以及承载凹部的承载面与底板的顶面具有断差的结构设计，使得当连接杆件的端部组装至卡扣端板后，连接杆件的端部可陷入承载凹部内而造成连接杆件整体朝底板靠近约断差的距离。再者，因连接杆件连接键帽与底板，故键帽亦可被连接杆件带动而朝底板靠近约断差的距离，如此按键的整体高度便可下降，进而有利于按键及键盘朝向薄型化的趋势发展。以上所述仅为本发明的较佳实施例，凡依本发明权利要求所做的均等变化与修饰，皆应属本发明的涵盖范围。Compared with the prior art, the present invention utilizes the load-bearing recess formed on the bottom plate and the structural design that the load-bearing surface of the load-bearing recess has a gap with the top surface of the bottom plate, so that when the end of the connecting rod is assembled to the buckle end plate , the end of the connecting rod can sink into the bearing recess, causing the whole connecting rod to approach the bottom plate by a distance of about a break. Furthermore, because the connecting rod connects the keycap and the bottom plate, the keycap can also be driven by the connecting rod to approach the bottom plate by a distance of about a break, so that the overall height of the key can be reduced, which is conducive to the thinning of the key and the keyboard. trend of development. The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the claims of the present invention shall fall within the scope of the present invention.
