Abstract
Description
本發明係有關於一種鉸鏈,尤指一種折疊式電子裝置的隱藏型對開鉸鏈。 The invention relates to a hinge, in particular to a concealed split hinge of a foldable electronic device.
一般電子裝置中,在傳統折疊式裝置方面,例如筆記型電腦的顯示器和底座,主要是透過單心軸鉸鏈分別接連顯示器側邊與底座以形成樞設,藉以使顯示器能相對於底座翻轉掀起或閉合。至近年,即有折疊式裝置是以至少兩機體取代傳統的顯示器和底座,再搭配一可撓性顯示器使用,其中,如中華人民共和國申請第CN 201810371007.2號之「隱藏式對開鉸鏈」專利案(下稱前案1)所示,其中有一實施例主要是包括一第一支撐件、一對開式轉軸、一第二支撐件、一多軸式轉軸以及一第三支撐件,供搭配一可撓性顯示器使用,藉以在整體摺疊呈S字狀或是Z字狀之後,讓對開式轉軸所連接的第一支撐件和第二支撐件能夠經由「單一虛擬旋轉中心」而閉合,並在對開式轉軸的內部形成一容置空間,以容納可撓性顯示器之彎曲狀區域部位。 In general electronic devices, in traditional folding devices, such as the display and the base of a notebook computer, the sides of the display and the base are connected respectively through a single-spindle hinge to form a pivot, so that the display can be flipped or lifted relative to the base. closure. In recent years, there have been foldable devices that use at least two bodies to replace the traditional display and base, and then use it with a flexible display. Among them, for example, the People’s Republic of China applied for the "Hidden Split Hinge" patent case No. CN 201810371007.2 ( Hereinafter referred to as the previous case 1), one of the embodiments mainly includes a first support, a pair of open shafts, a second support, a multi-axis shaft, and a third support for matching with a flexible The use of a sexual display, by which the first support and the second support connected by the split shaft can be closed through the "single virtual center of rotation" after the whole is folded into an S shape or a Z shape, and in the split type An accommodating space is formed inside the rotating shaft to accommodate the curved area of the flexible display.
之後再如後續改良的中華人民共和國申請第CN109488681A號之「隱藏式對開鉸鏈」(下稱前案2),則是增加了「蓋板搭配擺動件」結構,藉以在整體彎折及展平的過程中,能夠產生類似蹺蹺板的自由擺動作用,在整體彎折時,能讓出一容置空間以容納撓性顯示器的彎曲狀中間部位,而在整體展平時,則能對撓性顯示器的展平狀中間部位形成穩定的支撐。 After that, as the follow-up improvement of the People’s Republic of China applied for the "hidden split hinge" of CN109488681A (hereinafter referred to as the previous case 2), the structure of "cover plate with swinging piece" was added to bend and flatten the whole In the process, it can produce a free swinging effect similar to a seesaw. When the whole is bent, an accommodating space can be made to accommodate the curved middle part of the flexible display, and when the whole is flattened, the flexible display can be expanded. The flat middle part forms a stable support.
惟,不管是上述前案1之「單一虛擬旋轉中心」或是上述前案2所採用的「無軸翹翹板」結構,均在折疊式裝置之兩機體相互閉合後,讓其內部之可撓性顯示器之彎曲部位能夠形成小曲率,使整體薄型化,但是現今各家顯示器業者的技術發展存在差異,並非所有的可撓性顯示器之彎曲部位皆會形成小曲率,亦或是形成小曲率時會呈現出相異之彎曲樣態,因此,對於那些彎曲樣態相異之可撓性顯示器,就需要有對應合適之轉軸模組來搭配實施,而非完全採用上述前案1和2之結構設計,以減少可撓性顯示器受損的問題產生。有鑑於此,為了提供一種有別於習用技術之結構,並保有上述薄型化之優點,發明人積多年的經驗及不斷的研發改進,遂有本發明之產生。
However, whether it is the "single virtual center of rotation" in the

因此,本發明具有以下之優點: Therefore, the present invention has the following advantages:
1、本發明係採用「雙虛擬旋轉中心」,利用兩個轉動件相對於弧形座體同步轉動以替代「無軸翹翹板」結構所產生的補償動作,並在兩個轉動件相對摺疊時,仍能保有一容置空間以供容置可撓性顯示器的彎曲部位;因此,能夠有效簡化轉軸模組之動作,進而縮小整體厚度以利於設計,達到整體體積輕、薄之市場需求以促進銷售,並可以有效因應現有可撓性顯示器在彎折時的小曲率限制,以延長可撓性顯示器的使用壽命。 1. The present invention adopts "dual virtual rotation centers", using two rotating parts to rotate synchronously with respect to the arc-shaped seat body to replace the compensation action generated by the "shaftless rocker" structure, and the two rotating parts are folded relative to each other At this time, there is still a accommodating space for accommodating the bending part of the flexible display; therefore, the movement of the hinge module can be effectively simplified, and the overall thickness can be reduced to facilitate the design, so as to achieve the overall light and thin market demand. Promote sales, and can effectively cope with the small curvature limit of the existing flexible display when bending, so as to extend the service life of the flexible display.
2、本發明之各個扭力桿可以同步提供摩擦扭力,並能夠分擔負荷,讓兩個轉動件可以相對的穩定轉動,並在轉動時能自由停滯在一定角度上,更能進一步形成開輕關重之扭力變化並定位停滯在一特定角度上。而各個扭力桿除了可以複數個板片疊合組成之外,也能一體製造而成,以供實際情況對應實施,增加使用上的靈活性。 2. The torsion bars of the present invention can provide frictional torque synchronously, and can share the load, so that the two rotating parts can rotate relatively stably, and can freely stagnate at a certain angle during rotation, which can further form the opening light and closing weight. The torque changes and stops at a specific angle. In addition to being composed of multiple plates, each torsion bar can also be manufactured in one piece for practical implementation and increase flexibility in use.
3、本發明可將弧面塊、定位塊、轉動件及扭力桿等元件均採用模組化之結構設計,以方便組裝及製造。 3. The present invention can adopt modular structure design for the arc block, positioning block, rotating part, torsion bar and other elements to facilitate assembly and manufacturing.
