請參閱圖1和圖2，一種鍵盤10，其按鍵按力可調節，鍵盤10包括底板11、頂板12和按鍵13，底板11形成有側壁14，頂板12上還設置有按鍵通孔15，按鍵13位於按鍵通孔15中。鍵盤10還包括基板16、電磁鐵17、轉動部18和彈性件19。Referring to FIG. 1 and FIG. 2 , a keyboard 10 is provided with a button pressable force. The keyboard 10 includes a bottom plate 11 , a top plate 12 and a button 13 . The bottom plate 11 is formed with a side wall 14 , and the top plate 12 is further provided with a button through hole 15 . 13 is located in the button through hole 15. The keyboard 10 further includes a substrate 16, an electromagnet 17, a rotating portion 18, and an elastic member 19.
基板16固定於側壁14，基板16形成有凹槽20，凹槽20的底部形成有半圓形台階21，凹槽底部形成有裝配孔22，電磁鐵17固定於凹槽20的底部。The substrate 16 is fixed to the side wall 14, and the substrate 16 is formed with a groove 20. The bottom of the groove 20 is formed with a semicircular step 21, and the bottom of the groove is formed with a fitting hole 22, and the electromagnet 17 is fixed to the bottom of the groove 20.
請一併參閱圖3，轉動部18位於台階21上，其為圓環狀，其包括一通孔23。轉動部18面向凹槽20的底部的底面設置有第一磁體24和第二磁體25，第一磁體24和第二磁體25的磁性相反，轉動部18的頂面設置第三磁體26。Referring to FIG. 3 together, the rotating portion 18 is located on the step 21 and is annular, and includes a through hole 23. The bottom surface of the rotating portion 18 facing the bottom of the groove 20 is provided with a first magnet 24 and a second magnet 25, the magnetic properties of the first magnet 24 and the second magnet 25 are opposite, and the top surface of the rotating portion 18 is provided with a third magnet 26.
請一併參閱圖4和圖5，按鍵13的底部形成一延伸部27，延伸部27與裝配孔22滑動連接。按鍵13底部還設置有第四磁體28，第四磁體28與第三磁體26磁性相同。當電磁鐵17通第一方向的電流時，吸引第一磁體24，從而帶動轉動部18轉至第一位置，此時第三磁體26與第四磁體28對正；當電磁鐵17通以與第一方向反向的電流時，吸引第二磁體25，從而帶動轉動部18轉至第二位置，此時第三磁體26遠離第四磁體28；Referring to FIG. 4 and FIG. 5 together, an extension portion 27 is formed at the bottom of the button 13, and the extension portion 27 is slidably coupled to the fitting hole 22. A fourth magnet 28 is also provided at the bottom of the button 13, and the fourth magnet 28 is magnetically identical to the third magnet 26. When the electromagnet 17 passes the current in the first direction, the first magnet 24 is attracted, thereby rotating the rotating portion 18 to the first position, at which time the third magnet 26 is aligned with the fourth magnet 28; when the electromagnet 17 is connected When the first direction reverses the current, the second magnet 25 is attracted, thereby rotating the rotating portion 18 to the second position, at which time the third magnet 26 is away from the fourth magnet 28;
彈性件19的兩端分別與按鍵13和基板16相抵觸，彈性件19處於壓縮狀態。在本實施方式中，彈性件19為彈簧。Both ends of the elastic member 19 are in contact with the button 13 and the substrate 16, respectively, and the elastic member 19 is in a compressed state. In the present embodiment, the elastic member 19 is a spring.
在一個較佳實施例中，該鍵盤10的各元件的具體結構如下所述。In a preferred embodiment, the specific structure of the components of the keyboard 10 is as follows.
在本實施方式中，延伸部27的末端還形成有卡勾29，延伸部27穿過轉動部18的通孔23，延伸部27與通孔23之間具有間隙，卡勾29卡固於基板16。In the embodiment, the end of the extending portion 27 is further formed with a hook 29, the extending portion 27 passes through the through hole 23 of the rotating portion 18, and the gap between the extending portion 27 and the through hole 23 is provided, and the hook 29 is fixed on the substrate. 16.
當電磁鐵17通第一方向電流時，電磁鐵17吸引第一磁體24將轉動部18轉至預定角度，此時轉動部18處於第一位置，第三磁體26與第四磁體28對正。由於按鍵13受到磁體間排斥力的作用，使得用戶按下按鍵13需要克服彈性件19和第三磁體26與第四磁體28之間的排斥力的阻力，此時按鍵13的按力為第一按力。當電磁鐵17通以與第一方向反向的電流時，電磁鐵17吸引第二磁體25將轉動部18轉至預定角度，此時轉動部處於第二位置，第三磁體26遠離第四磁體28，由於按鍵13受到磁體間排斥力變小，使得用戶按下按鍵13需要克服彈性件19和第三磁體26與第四磁體28之間的排斥力的阻力也變小，此時按鍵13的按力為第二按力。按鍵13的第二按力比第一按力小。When the electromagnet 17 is energized in the first direction, the electromagnet 17 attracts the first magnet 24 to rotate the rotating portion 18 to a predetermined angle, at which time the rotating portion 18 is in the first position, and the third magnet 26 is aligned with the fourth magnet 28. Since the button 13 is subjected to the repulsive force between the magnets, the user needs to overcome the resistance of the repulsive force between the elastic member 19 and the third magnet 26 and the fourth magnet 28 when the button 13 is pressed, and the pressing force of the button 13 is the first. Press force. When the electromagnet 17 is energized with a current opposite to the first direction, the electromagnet 17 attracts the second magnet 25 to rotate the rotating portion 18 to a predetermined angle, at which time the rotating portion is in the second position, and the third magnet 26 is away from the fourth magnet. 28, since the button 13 is weakened by the repulsive force between the magnets, the resistance of the user to press the button 13 to overcome the repulsive force between the elastic member 19 and the third magnet 26 and the fourth magnet 28 is also small, and at this time, the button 13 is Press force as the second force. The second pressing force of the button 13 is smaller than the first pressing force.
上述第一磁體24、第二磁體25、第三磁體26和第四磁體28均為磁鐵或導磁的金屬。The first magnet 24, the second magnet 25, the third magnet 26, and the fourth magnet 28 are all magnets or magnetically permeable metals.
通過改變上述電磁鐵17的磁性來帶動轉動部18轉至預定角度，使按鍵13和轉動部18之間的磁力發生變化，從而使按鍵13的按力可調。By changing the magnetic properties of the electromagnet 17, the rotating portion 18 is rotated to a predetermined angle, and the magnetic force between the button 13 and the rotating portion 18 is changed, so that the pressing force of the button 13 is adjusted.
為了使按鍵13受力更均衡，按鍵13的底部和轉動部18面向按鍵13的一面可設置若干相適應的磁體。In order to make the button 13 more evenly balanced, the bottom of the button 13 and the side of the rotating portion 18 facing the button 13 may be provided with a plurality of adapted magnets.
可以理解地，如手機等的電子裝置亦可採用上述鍵盤10的全部結構，從而使得該電子裝置具有按鍵按力可調節的鍵盤。It can be understood that an electronic device such as a mobile phone can also adopt the entire structure of the keyboard 10 described above, so that the electronic device has a keyboard with a button press adjustable.
