Description
本創作涉及開關裝置，具體涉及一種超薄平衡按鍵。The invention relates to a switch device, in particular to an ultra-thin balanced key.
輸入設備是指向計算機輸入數據和訊息的設備，是計算機與用戶或其他設備通信的橋樑，諸如鍵盤等。鍵盤是由若干按鍵開關組合而成。The input device is a device that points to the computer to input data and information, and is a bridge for the computer to communicate with the user or other devices, such as a keyboard. The keyboard is composed of several key switches.
現有的電子設備越來越小型化，對鍵盤的輕薄要求也越來越高。以筆記型電腦為例，現在筆記型電腦重量只有1kg左右，整機厚度只有13mm左右，開關按鍵的鍵程只有1.5mm左右，為了滿足電子設備的輕薄設計，影響厚度的最大障礙之一就是鍵盤的厚度，而影響鍵盤厚度的核心問題是按鍵開關的高度（厚度），如何將按鍵開關做到超薄且不影響按壓時候的平衡穩定性，確保使用者在按壓鍵帽不同位置的時候都能準確穩定產生開關訊號，這是本領域的技術難題。現有技術中，為了實現超薄按鍵開關的平衡穩定按壓，基本上都採用鍵程較小的剪刀腳來實現，但剪刀腳本身的機構原理限制了無法再進一步的做到更薄。Existing electronic devices are becoming more and more miniaturized, and the requirements for thinner and lighter keyboards are also getting higher and higher. Take the notebook computer as an example. Now the weight of the notebook computer is only about 1kg, the thickness of the whole machine is only about 13mm, and the key stroke of the switch button is only about 1.5mm. In order to meet the thin and light design of electronic equipment, one of the biggest obstacles affecting the thickness is the keyboard. The thickness of the keyboard, and the core issue that affects the thickness of the keyboard is the height (thickness) of the key switch. How to make the key switch ultra-thin without affecting the balance and stability when pressing, so as to ensure that the user can press the key cap at different positions. Accurate and stable generation of switching signals is a technical problem in this field. In the prior art, in order to realize the balanced and stable pressing of ultra-thin key switches, scissors feet with a small key stroke are basically used to achieve this. However, the mechanism principle of the scissors feet itself limits the ability to further make it thinner.
此外，現有技術中，為了實現更長的按鍵開關壽命、防塵防水等技術效果，大量的採用光電開關以取代傳統的金屬觸片、觸點等開關。光電開關是通過光柵改變受光元件所接收到的來自於發光元件的光量，以形成開關訊號的一種開關。In addition, in the prior art, in order to achieve longer key switch life, dustproof and waterproof and other technical effects, a large number of photoelectric switches are used to replace traditional metal contacts, contacts and other switches. A photoelectric switch is a switch that changes the amount of light received by the light-receiving element from the light-emitting element through a grating to form a switch signal.
