With the advancement of technology, consumer electronics products are gradually moving towards a thin and light design trend, so the button mechanism has accordingly designed a lighter and thinner structure suitable for use in thin electronic products. Most of the conventional buttons use a scissor-foot structure with an elastic body to perform the function of resetting the key cap, but the structure is bulky and difficult to apply in ultra-thin electronic products. Therefore, how to design a button and its related keyboard that can combine high structural strength and light and thin shape is an urgent development goal for the current institutional industry.

The third magnetic element 38, the fourth magnetic element 40, the fifth magnetic element and the sixth magnetic element may be distributed in a quadrangular shape around the upper portion 30 of the keycap, such as the four segments 22A shown in FIG.
請參閱第6圖,第6圖為本創作第三實施例之磁吸式按鍵14”之示意圖。第三實施例中,與前述實施例相同編號之元件具有相同的結構及功能,於此不再詳述。第三實施例與前述實施例之差異在於,磁吸式按鍵14”之容置空間28係為限位部26與底板12組成,用來防止鍵帽底部32脫離。容置空間28具有一垂直高度H與一水平寬度W,其中,鍵帽20沿著預設方向D相對底板12的移動行程實質接近容置空間28之垂直高度H,且容置空間28的水平寬度W實質接近鍵帽底部32的上表面寬度,因此鍵帽20和支撐架16不 會發生干涉。磁吸式按鍵14”之開關42可設置於鍵帽20的下方。使用者係按壓鍵帽20以驅動下移,鍵帽20觸碰到開關42時,開關42才會被啟動而輸出一電子訊號。Please refer to FIG. 6 , which is a schematic diagram of the magnetic button 14 ′′ according to the third embodiment of the present invention. In the third embodiment, the same components as the foregoing embodiments have the same structure and function, and Further, the difference between the third embodiment and the foregoing embodiment is that the accommodating space 28 of the magnetic button 14" is composed of the limiting portion 26 and the bottom plate 12 for preventing the key cap bottom portion 32 from being detached. The accommodating space 28 has a vertical height H and a horizontal width W, wherein the movement distance of the keycap 20 along the predetermined direction D relative to the bottom plate 12 is substantially close to the vertical height H of the accommodating space 28, and the level of the accommodating space 28 The width W is substantially close to the width of the upper surface of the keycap bottom 32, so the keycap 20 and the support frame 16 are not Interference will occur. The switch 42 of the magnetic button 14" can be disposed under the keycap 20. The user presses the keycap 20 to drive down, and when the keycap 20 touches the switch 42, the switch 42 is activated to output an electronic Signal.
第三實施例的磁吸式按鍵14”另可包含第五磁吸元件。第三磁吸元件38、第四磁吸元件40與第五磁吸元件可呈三角形分佈而圍繞鍵帽上部30,如第3圖所示的三個區段22A。再者,磁吸式按鍵14”還可包含第五磁吸元件與第六磁吸元件。第三磁吸元件38、第四磁吸元件40、第五磁吸元件與第六磁吸元件可呈四邊形分佈而圍繞鍵帽上部30,如第4圖所示的四個區段22A。The magnetic button 14" of the third embodiment may further comprise a fifth magnetic element. The third magnetic element 38, the fourth magnetic element 40 and the fifth magnetic element may have a triangular distribution around the upper portion 30 of the keycap, The three sections 22A are shown in Fig. 3. Further, the magnetic button 14" may further include a fifth magnetic element and a sixth magnetic element. The third magnetic element 38, the fourth magnetic element 40, the fifth magnetic element and the sixth magnetic element may be distributed in a quadrangular shape around the upper portion 30 of the keycap, such as the four segments 22A shown in FIG.
此外,在第三實施例中,垂直高度H與水平寬度W的比值可實質小於0.3,使得鍵帽20在容置空間28內的最大傾斜角度可實質小於17度。如此一來,磁吸式按鍵14”雖使用磁吸元件提供鍵帽20復位的驅動力,鍵帽20未有實體的支撐機構,但藉由容置空間28的尺寸設計仍可確保鍵帽20在按壓過程中不會過度傾斜。欲進一步將磁吸式按鍵14”應用在薄型鍵盤,可將垂直高度H與水平寬度W的比值設計為實質小於0.05,如此鍵帽20在容置空間28內的最大傾斜角度則會實質小於3度,以避免鍵帽20在按壓過程有過大的傾斜翻轉,進而可提高磁吸式按鍵14”的操作手感。Further, in the third embodiment, the ratio of the vertical height H to the horizontal width W may be substantially less than 0.3, so that the maximum inclination angle of the keycap 20 in the accommodating space 28 may be substantially less than 17 degrees. In this way, the magnetic button 14" uses the magnetic element to provide the driving force for the resetting of the keycap 20, and the keycap 20 does not have a physical supporting mechanism, but the size of the receiving space 28 ensures the keycap 20 There is no excessive tilt during the pressing process. To further apply the magnetic button 14" to the thin keyboard, the ratio of the vertical height H to the horizontal width W can be designed to be substantially less than 0.05, so that the keycap 20 is in the accommodating space 28. The maximum tilt angle is substantially less than 3 degrees to avoid excessive tilting of the keycap 20 during the pressing process, thereby improving the operational feel of the magnetic button 14".
綜上所述,本創作之磁吸式按鍵及其鍵盤利用複數個對應排列的磁吸單元或磁吸元件產生磁性吸附力。使用者在按壓鍵帽時,施加外力克服磁性吸附力以提供較佳的操作手感;在移除外力後,磁性吸附力可吸引鍵帽上升而回到初始位置。本創作之鍵帽受磁性吸附力的驅動方向實質平行於鍵帽相對底板的運動方向,磁性吸附力為支撐鍵帽上升的機制,意即鍵帽在磁性吸附力大於施加外力時上升,在施加外力大於磁性吸附力時下降,其具有結構簡單、操作容易之優點,並可大幅縮減所佔的空間,有利於應用在薄型鍵盤。In summary, the magnetic button and its keyboard of the present invention utilize a plurality of correspondingly arranged magnetic or magnetic elements to generate magnetic attraction. When the user presses the keycap, an external force is applied to overcome the magnetic attraction force to provide a better operational feel; after the external force is removed, the magnetic attraction force can attract the keycap to rise back to the initial position. The driving direction of the keycap of the present invention is substantially parallel to the moving direction of the keycap relative to the bottom plate, and the magnetic attraction force is a mechanism for supporting the rise of the keycap, that is, the keycap rises when the magnetic attraction force is greater than the applied external force, and is applied When the external force is larger than the magnetic adsorption force, the utility model has the advantages of simple structure and easy operation, and can greatly reduce the occupied space, and is beneficial to the thin keyboard.
