Description
本發明與電梯之按鍵有關，特別是指一種可提升作動確實度之按鍵裝置。 The invention relates to a button of an elevator, in particular to a button device capable of improving the accuracy of actuation.
電梯主要是用來提供載運功能，當人員在進入電梯之後，通常是先利用啟閉按鍵控制電梯門關閉，接著再利用樓層按鍵選擇想要到達的樓層，此時的電梯便會移動到搭乘人員所選擇的樓層。 The elevator is mainly used to provide the carrying function. When the person enters the elevator, the elevator door is usually controlled by the opening and closing button, and then the floor button is used to select the floor to be reached. At this time, the elevator will move to the passenger. The selected floor.
然而不論是啟閉按鍵或樓層按鍵，為了在按壓力量解除之後能夠立即回復到初始狀態，在先前技術當中，按鍵的背面通常是藉由兩條相對設置之彈簧作為對按鍵提供復位效果之用，但是因為兩條彈簧之間缺乏結構上的連動關係，所以只要按壓的位置有所偏差，按鍵很可能就無法跟內部的電路板形成電性導通，這時候的搭乘人員必須要釋放按壓力量之後再改變位置重新按壓一次，直到成功為止。因此，傳統使用彈簧之按鍵在結構方面的作動確實度並不理想。 However, whether it is the opening and closing button or the floor button, in order to immediately return to the initial state after the pressing force is released, in the prior art, the back of the button is usually provided by the two oppositely disposed springs as a reset effect for the button. However, because there is a lack of structural linkage between the two springs, as long as the position of the pressing is deviated, the button may not be electrically conductive with the internal circuit board. At this time, the rider must release the pressing force. Change the position and press again until it is successful. Therefore, the traditional use of the spring button is not ideal in terms of structural operation.

The first stop portion 28 of the button base 20 is configured to enable the button 50 to move stably and smoothly relative to the button holder 20, and the button 50 is engaged with the first stop portion of the button holder 20 by the second stopping portion 52. 28, to avoid separation between the button 50 and the button holder 20. In addition, the four corners of the button 50 have two opposite first slots 53 and two opposite second slots 54. The buttons 50 are respectively engaged with the first link 41 by the first and second slots 53 and 54. The first card shaft 421 of the first main rod body 42 and the second card shaft 452 of the second main rod body 45 of the second link 44 enable the button 50 to simultaneously push the first and second links when the pressing force is applied Rods 41, 44.
如第2及4圖所示，連動彈片60是由金屬材質所製成。連動彈片60之中央具有一抵壓部61，抵壓部61對應於開關32之觸發部322，連動彈片60之兩端分別具有一卡接部62，兩個卡接部62分別穿設於第一連桿41之第一穿槽422及第二連桿44之第二穿槽454內且分別卡接於第一連桿41之第一主桿體42的中央及第二連桿44之第二主桿體45的中央，使得連動彈片60能跟第一、第二連桿41、44同步作動。 As shown in Figures 2 and 4, the interlocking elastic piece 60 is made of a metal material. The center of the interlocking elastic piece 60 has a pressing portion 61. The pressing portion 61 corresponds to the triggering portion 322 of the switch 32. The two ends of the interlocking elastic piece 60 respectively have a latching portion 62. a first through slot 422 of a link 41 and a second through slot 454 of the second link 44 are respectively engaged with the center of the first main rod 42 of the first link 41 and the second link 44 The center of the two main rods 45 enables the interlocking elastic pieces 60 to be synchronized with the first and second links 41, 44.
如第2及4圖所示，受壓彈片70是由金屬材質所製成。受壓彈片70之兩端分別卡接於按鍵座20之彈片固定部27，使得受壓彈片70的長度方向會垂直於連動彈片60的長度方向，此外，受壓彈片70具有一受壓部71，受壓部71的位置介於開關32之觸發部322與連動彈片60之抵壓部61之間，使得受壓彈片70之受壓部71在受到連動彈片60之抵壓部61的推頂時會碰觸開關32之觸發部322。 As shown in Figures 2 and 4, the compressed elastic piece 70 is made of a metal material. The two ends of the compressed elastic piece 70 are respectively engaged with the elastic piece fixing portion 27 of the key base 20 such that the longitudinal direction of the compressed elastic piece 70 is perpendicular to the longitudinal direction of the interlocking elastic piece 60. Further, the compressed elastic piece 70 has a pressure receiving portion 71. The position of the pressure receiving portion 71 is interposed between the triggering portion 322 of the switch 32 and the pressing portion 61 of the interlocking elastic piece 60, so that the pressed portion 71 of the compressed elastic piece 70 is pushed by the pressing portion 61 of the interlocking elastic piece 60. The trigger portion 322 of the switch 32 is touched.
如第2及7圖所示，背光模組80具有多個光源81、一擴散膜82、一導光板83及一反射片84。光源81以相互並排的方式設於電路板30且位於按鍵座20之一側邊，擴散膜82設於按鍵50朝按鍵座20之一側面，導光板83之兩側面分別連接擴散膜82及反射片84。 As shown in FIGS. 2 and 7, the backlight module 80 has a plurality of light sources 81, a diffusion film 82, a light guide plate 83, and a reflection sheet 84. The light source 81 is disposed on the circuit board 30 side by side and on one side of the button base 20. The diffusion film 82 is disposed on one side of the button 50 toward the button holder 20. The two sides of the light guide plate 83 are respectively connected to the diffusion film 82 and reflected. Slice 84.
由上述結構可知，如第6及7圖所示，當按鍵50受到按壓時，首先按鍵50會推動第一連桿41之第一主桿體42及第二連桿44之第二主桿體45，使第一連桿41之第一主桿體42與第二連桿44之第二主桿體45同時朝電路板30的方向樞轉，接著第一連桿41之第一主桿體42與第二連桿44之第二主桿體45會再推動連動彈片60之卡接部62，使連動彈片60之抵壓部61推動受壓彈片70之受壓部71，一旦受壓彈片70之受壓部71 碰觸到開關32之觸發部322時即完成電性導通，此時的電路板30會控制光源81產生光線，光源81所產生的光線會再透過反射片84、導光板83及擴散膜82來達到提升亮度及均勻分佈的效果。在釋放對按鍵50的力量之後，受壓彈片70會藉由本身之彈性回復力推頂連動彈片60，接著連動彈片60會再配合本身的彈性回復力推頂第一連桿41之第一主桿體42及第二連桿44之第二主桿體45，使第一、第二連桿41、44將按鍵50推頂至按壓前的狀態。 As can be seen from the above structure, as shown in FIGS. 6 and 7, when the button 50 is pressed, the button 50 first pushes the first main body 42 of the first link 41 and the second main body of the second link 44. 45, the first main rod body 42 of the first link 41 and the second main rod body 45 of the second link 44 are simultaneously pivoted toward the circuit board 30, and then the first main rod body of the first link 41 The second main body 45 of the second link 44 and the second link 44 of the second link 44 pushes the engaging portion 62 of the interlocking elastic piece 60 again, so that the pressing portion 61 of the interlocking elastic piece 60 pushes the pressed portion 71 of the compressed elastic piece 70 once the compressed elastic piece is pressed. 70 pressure part 71 When the triggering portion 322 of the switch 32 is touched, the electrical conduction is completed. At this time, the circuit board 30 controls the light source 81 to generate light, and the light generated by the light source 81 is transmitted through the reflective sheet 84, the light guide plate 83, and the diffusion film 82. Achieve improved brightness and even distribution. After releasing the force on the button 50, the compressed elastic piece 70 will push the interlocking elastic piece 60 by its own elastic restoring force, and then the interlocking elastic piece 60 will cooperate with its own elastic restoring force to push the first main link of the first connecting rod 41. The second main body 45 of the rod 42 and the second link 44 causes the first and second links 41 and 44 to push the button 50 to the state before pressing.
在此值得一提的是，受壓彈片70是為了增加按鍵50的使用手感，因此可以根據實際需要而省略不設置，若是在沒有設置受壓彈片70的情況下，在按壓按鍵50時是利用連動彈片60之抵壓部61直接碰觸開關32之觸發部322來形成電性導通。 It is worth mentioning that the compressed elastic piece 70 is for increasing the hand feeling of the button 50, and therefore can be omitted according to actual needs. If the compressed elastic piece 70 is not provided, the pressing of the button 50 is utilized. The pressing portion 61 of the interlocking elastic piece 60 directly touches the trigger portion 322 of the switch 32 to form electrical conduction.
另一方面，假如按鍵50的受壓位置並非在正中央，而是偏向於第一連桿41或第二連桿44的狀況下，由於第一連桿41之第一側桿體43與第二連桿44之第二側桿體46之間是相互樞接在一起，所以透過槓桿原理的應用，只要第一、第二連桿41、44的其中之一受到按鍵50的推力，第一、第二連桿41、44的另外之一還是會跟著一起作動，如此可以達到受力平衡的效果。 On the other hand, if the pressed position of the button 50 is not in the center, but is biased toward the first link 41 or the second link 44, the first side bar 43 of the first link 41 and the first The second side rods 46 of the two links 44 are pivotally connected to each other, so the application of the principle of the lever is as long as one of the first and second links 41, 44 is subjected to the thrust of the button 50, first The other one of the second links 41, 44 will still be operated together, so that the force balance effect can be achieved.
綜上所陳，本發明之按鍵裝置10利用第一、第二連桿41、44的結構配置，不但可以簡化組裝過程，而且不論按壓到按鍵50的任何一個位置都順利完成電性導通，進而達到提升作動確實度的目的。 In summary, the key device 10 of the present invention utilizes the structural configuration of the first and second links 41, 44, which not only simplifies the assembly process, but also smoothly completes electrical conduction regardless of pressing to any position of the button 50. To achieve the purpose of improving the accuracy of the action.
