Abstract
Description
本發明係有關於一種轉軸,尤指一種折疊式電子裝置的轉軸模組。 The invention relates to a rotating shaft, in particular to a rotating shaft module of a folding electronic device.
傳統折疊式電子裝置,例如中華人民共和國發明公布第CN105788452 A號之「可折疊顯示器」專利案所示,即顯示了一種轉軸之折疊結構,其主要是以鉸接件之第一主體、第三主體分別與第一支撐件和第二支撐件彼此連接,並使第一支撐件及第二支撐件結合一柔性顯示模組,藉以在第一主體、第三主體相對於第二主體轉動之後,讓第一支撐件和第二支撐件上的柔性顯示模組折疊在一起。其由於需要在第二主體上設置可以讓第一、第三主體轉動之結構,因此無法有效縮減兩個機體之間能留給轉軸容置的間距,此種設計將使得整體之體積變大,不但不利於電子裝置之整體設計,且不符合整體體積逐漸趨向輕、薄的市場需求。 Traditional folding electronic devices, as shown in the Patent Foldable Display of Patent Publication No. CN105788452 A of the People’s Republic of China, show a folding structure of a rotating shaft, which is mainly composed of a first body and a third body of a hinge Are respectively connected to the first support member and the second support member, and the first support member and the second support member are combined with a flexible display module, so that after the first body and the third body rotate relative to the second body, the The flexible display modules on the first support and the second support are folded together. Due to the need to provide a structure on the second body that allows the first and third bodies to rotate, it is not possible to effectively reduce the space between the two bodies that can be reserved for the rotating shaft. This design will increase the overall volume. Not only is it not conducive to the overall design of the electronic device, but also does not meet the market demand that the overall volume gradually becomes lighter and thinner.
而如CN103576775A、CN106205385A及US9250733B三件專利案所示,則是分別以雙軸式轉軸或是近似雙軸式的結構使兩個機體形成相對開闔;且這三件專利案的「支撐結構」都是將其中一端部透過「實體軸」形成樞接而另一端部活動,在整個「折疊式裝置」閉合時,兩機體中的各個支撐結構均會受到另一施力件,例如:彈簧、拉簧、吸鐵、扭簧之帶動,在內部讓出一個容置空間,供容納撓性顯示器之彎曲狀中間部位,並在整個折疊式裝置展平 時,以各個支撐結構分別支撐撓性顯示器之展平狀中間部位。再如中華人民共和國發明公布第CN106255935A號「折疊式設備」專利案及第CN103034293B號「顯示系統」專利案二件專利案,則是分別以一或二連桿組成連桿組,以推動被「實體軸」樞接的「支撐結構」產生位移,使達到縮減間距以容納「撓性顯示器彎曲部位」之效果。此種「可補償摺疊路徑之機構」的設計概念同樣也顯示在US9791892B及US10001810B二案之中,其中,US9791892B一案可視為CN106255935A之圖16a~16c的延伸案,而US10001810B案則是在其一機體(圖2的220和圖9的920)中設有「可補償摺疊路徑之機構」,包括平移板(圖2的225和圖9的921部位)、連桿組件(圖2的330和圖9的920)或齒輪組件(圖10a的340)搭配引導件(圖9的331和圖10a的341),以達到補償折疊路徑差的效果。 As shown in the three patent cases of CN103576775A, CN106205385A, and US9250733B, the two bodies are relatively opened and closed with a two-axis rotating shaft or an approximately two-axis structure; and the "support structure" of these three patent cases All one end is pivotally connected through the "solid shaft" and the other end is movable. When the entire "folding device" is closed, each support structure in the two bodies will be subjected to another urging member, such as: spring, Driven by tension springs, iron suction, and torsion springs, an internal accommodating space is provided for accommodating the curved middle part of the flexible display, and flattened throughout the folding device At this time, each support structure separately supports the flattened middle portion of the flexible display. Another example is the invention of the People's Republic of China that published the patent case No. CN106255935A "Folding Equipment" and the patent case No. CN103034293B "Display System", which consisted of one or two connecting rods to form a linkage group to promote The "supporting structure" where the "solid axis" is pivotally connected is displaced, so that the distance is reduced to accommodate the "flexible display bending part" effect. The design concept of this "compensation mechanism that can compensate for the folding path" is also shown in the two cases of US9791892B and US10001810B. Among them, the case of US9791892B can be regarded as an extension of Figures 16a~16c of CN106255935A, and the case of US10001810B is in one. The body (220 in FIG. 2 and 920 in FIG. 9) is provided with a "mechanism that can compensate for the folding path", including a translation plate (225 in FIG. 2 and 921 in FIG. 9), a link assembly (330 and FIG. 2 in FIG. 2) 9 of 920) or a gear assembly (340 of FIG. 10a) with a guide (331 of FIG. 9 and 341 of FIG. 10a) to achieve the effect of compensating for the difference in folding path.
惟,上述各專利案所使用「可補償摺疊路徑之機構」的各零件連接關係及結構皆相當複雜,且大都是利用直接樞接的結構,其在傳動穩定性方面並不甚理想,且其「支撐結構」在產生位移,使達到縮減間距以容納「撓性顯示器彎曲部位」的過程中,由於相對移動以進行縮減的速度相同,很容易就會因為摺疊動作的力道不平順而對撓性顯示器造成拉扯或推擠之現象,讓撓性顯示器之中間彎曲部位產生皺摺或剝離。有鑑於此,為了提供一種有別於習用技術之結構,並改善上述之缺點,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, the connection relationship and structure of each part of the "mechanism that can compensate for the folding path" used in the above patent cases are quite complicated, and most of them use a direct pivot connection structure, which is not ideal in terms of transmission stability, and its In the process of the displacement of the "support structure" to reduce the pitch to accommodate the "flexible display bending part", since the relative movement to reduce the speed is the same, it is easy to be flexible because of the uneven force of the folding action. The display may be pulled or pushed, causing wrinkles or peeling in the middle bend of the flexible display. In view of this, in order to provide a structure different from the conventional technology and to improve the above-mentioned shortcomings, the inventor has accumulated many years of experience and continuous research and development improvements, and the invention has been produced.

And in the whole bending and flattening, when the second connecting portion of the supporting plate body swings relative to the first connecting portion of the first slider in an arc shape, a free swinging effect similar to a shaftless seesaw can be generated to maintain the stability of the transmission . It does not need to be pivotally connected with a solid axis as in the conventional technology. When the whole is bent, it can provide a receiving space to accommodate the curved middle part of the flexible display, and when the whole is flat, it can expand the flexible display. The flat middle part forms a stable support.

藉此,當第一殼體11與第二殼體12相對翻轉展開而呈現展平之狀態時,支撐板341一端之限位部343可以經由導引面315之導引,以順暢的搭接限位於基座2之第一擋止部23上,藉以限制支撐板體34之作動,讓二個支撐板341向上支撐撓性顯示器13。此時,第一滑移機構3與第二滑移機構3’之復位件345分別被拉伸以蓄積彈力。
Thereby, when the
而如第7~9圖所示,當第一殼體11與第二殼體12相對翻轉閉合而讓二組固定殼體(111,121)及活動殼體(112,122)分別拉開距離時,經由第一滑移機構3及第二滑移機構3’的同時作動及二個復位件345之彈力回復作用,即可使兩組滑移機構之支撐板341之限位部343分別與基座2之第一擋止部23、第二擋止部26相對滑動分開,從而使二個限位部343同時脫離第一擋止部23及第二擋止部26之限制,另,本案整體係為薄型化之結構,所能提供各零件作動之空間有限,因此,為了降低二個限位部343之偏移動作遭受細微間隙及段差之影響,接續透過兩組滑移機構之導引面315分別承接及導引二個限位部343,並讓二個支撐板體34分別相對於二個第一滑塊32持續進行弧形擺動,以使二個支撐板341分別偏移一角度之後,會承靠在兩組滑移機構之支撐面316,並同時讓二個連接板342抵壓在第一滑塊32一端之斜面322上,形成多個接觸面以分擔負荷並均勻支撐,又使連動板35之層疊結構可平躺於鏤空槽317中以靠近固定殼
體(111,121)之壁面,以防支撐板341承靠時發生干涉連動板35之情形。而由於兩個滑移機構之兩個支撐板341在相對偏移一角度之後,則會形成一容置空間14以容納撓性顯示器13之中間彎曲部位。
As shown in FIGS. 7-9, when the
因此,本發明具有以下之優點: Therefore, the present invention has the following advantages:
1、本發明經由第一滑塊、支撐板體、連動板以及一齒輪模組之間的連接關係及結構特徵,可以有效薄型化「補償摺疊路徑機構」的整體,進一步可簡化使用零件以降低生產成本。而經由支撐板體之第二連接部相對於第一滑塊之第一連接部弧形擺動,產生類似無軸蹺蹺板的自由擺動作用,即無需如習用技術一般的以實體軸樞接,亦有助於縮減體積並降低厚度,以利於薄型化之效果,使在整體彎摺時,能讓出容置空間以容納撓性顯示器之彎曲狀中間部位,而在整體展平時,又能對撓性顯示器之展平狀中間部位形成穩定之支撐。 1. The present invention can effectively thin the whole of the "compensation folding path mechanism" through the connection relationship and structural characteristics between the first slider, the support plate body, the linkage plate and a gear module, and can further simplify the use of parts to reduce Cost of production. The second connecting portion of the support plate body swings relative to the first connecting portion of the first slider in an arc shape to produce a free swinging effect similar to a shaftless seesaw, that is, it does not need to be pivotally connected with a physical axis as in conventional technology. Helps to reduce the volume and thickness, in favor of the effect of thinning, so that when the whole is bent, it can make a room to accommodate the curved middle part of the flexible display, and when the whole is flat, it can be flexible The flattened middle part of the display forms a stable support.
2、本發明係透過具有不同齒比之中間齒輪分別齒合第一齒條及第二齒條,讓連接第一齒條之固定殼體與連接第二齒條之活動殼體能形成不同之移動速度,以避免摺疊動作的力道對撓性顯示器造成拉扯或推擠,不但能達到補償折疊路徑差之功效,且可以有效延長撓性顯示器之使用壽命。 2. In the present invention, the intermediate gears with different gear ratios are respectively engaged with the first rack and the second rack, so that the fixed casing connected to the first rack and the movable casing connected to the second rack can form different movements Speed, to avoid pulling or pushing the flexible display by the force of the folding action, can not only achieve the effect of compensating for the difference in the folding path, but also effectively extend the service life of the flexible display.
3、本發明係經由一伸縮模組之壓縮彈簧之彈性作用以使固定殼體與活動殼體形成反向之作用力,從而讓第一齒條與第二齒條皆能持續性的分別抵壓住中間齒輪之第一齒輪部及第二齒輪部,因此,可以有效消除各齒之間的間隙,以維持穩定的傳動效果。 3. The present invention uses the elastic action of the compression spring of a telescopic module to make the fixed shell and the movable shell form a reverse force, so that the first rack and the second rack can continuously resist The first gear portion and the second gear portion of the intermediate gear are pressed, so that the gap between the teeth can be effectively eliminated to maintain a stable transmission effect.
4、本發明係透過底座兩側之間的鏤空槽,供連動板之上下層疊結構置入以有利於活動,並有助於整體薄型化後之內部零件的連動;而再加上基座同一軸心上之兩個樞接點以及第一齒條之導柱搭配底座之長導 槽等技術手段,則可利於穩定第一齒條及伸縮模組之作動影響。 4. The present invention uses hollowed grooves between the two sides of the base for placing the linking plate on the top and bottom stacking structure to facilitate movement and to facilitate the linkage of the internal parts after the overall thinning; and the same base The two pivot points on the axis and the guide post of the first rack match the long guide of the base Technical means such as grooves can help stabilize the action of the first rack and the expansion module.
