折疊式裝置的轉軸模組(一)Rotary shaft module of folding device (1)

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。A conventional folding electronic device, as shown in the "Foldable Display" patent of No. CN105788452 A of the People's Republic of China, discloses a folding structure of a rotating shaft, which is mainly a first body and a third body of a hinge member. Separating the first support member and the second support member with each other, and combining the first support member and the second support member with a flexible display module, so that after the first body and the third body are rotated relative to the second body, The flexible display modules on the first support and the second support are folded together. Because of 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 spacing between the two bodies that can be reserved for the rotation of the shaft. This design will make the overall volume larger. Not only is it not conducive to the overall design of the electronic device, and does not meet the market demand for the overall volume gradually becoming 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 patents of CN103576775A, CN106205385A and US9250733B, the two bodies are formed in a relatively open state by a biaxial shaft or an approximately two-axis structure; and the "support structure" of the three patents. One end is pivoted through the "solid shaft" and the other end is moved. When the entire "folding device" is closed, each supporting structure in the two bodies is subjected to another force applying member, such as a spring, The tension spring, the suction iron and the torsion spring drive an internal accommodation space for accommodating the curved intermediate portion of the flexible display, and respectively support the flexible display with each support structure when the entire folding device is flattened. Flatten the middle part. In addition, the People's Republic of China Invention and Publication No. CN106255935A "Folding Equipment" Patent Case and the CN103034293B "Display System" Patent Case Two Patent Cases, respectively, are composed of one or two links to form a link group to promote " The "support structure" pivoted by the solid axis is displaced so that the reduced pitch is achieved to accommodate the "flexure of the flexible display". The design concept of such a mechanism for compensating the folding path is also shown in the US9791892B and US10001810B cases, wherein the US9791892B case can be regarded as the extension of Figures 16a-16c of CN106255935A, and the US10001810B case is in one case. The body (220 of Fig. 2 and 920 of Fig. 9) is provided with a "mechanism capable of compensating the folding path", including a translating plate (225 of Fig. 2 and part 921 of Fig. 9), and a link assembly (330 of Fig. 2 and Fig. 2). The 920) of 9 or the gear assembly (340 of Figure 10a) is matched with guides (331 of Figure 9 and 341 of Figure 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 relationships and structures of the various components used in the above-mentioned patents are "complex mechanisms for compensating the folding path", and most of them use a direct pivoting structure, which is not ideal in terms of transmission stability, and When the "support structure" is displaced so that the reduced pitch is accommodated to accommodate the "flexible portion of the flexible display", the speed of the reduction is the same because of the relative movement, and it is easy to be flexible due to the uneven force of the folding action. The display causes pulling or pushing, causing wrinkles or peeling of the curved portion of the flexible display. In view of the above, in order to provide a structure different from the conventional technology and to improve the above disadvantages, the inventors have accumulated many years of experience and continuous development and improvement, and the present invention has been produced.

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 first housing 11 and the second housing 12 are relatively unfolded and deployed to be flattened, the limiting portion 343 at one end of the support plate 341 can be guided through the guiding surface 315 for smooth overlapping. It is limited to the first stopping portion 23 of the base 2, thereby restricting the operation of the supporting plate body 34, and the two supporting plates 341 support the flexible display 13 upward. At this time, the reset members 345 of the first slip mechanism 3 and the second slip mechanism 3' are respectively stretched to accumulate the elastic force.

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 first housing 11 and the second housing 12 are relatively turned over and closed, and the two sets of the fixed housing (111, 121) and the movable housing (112, 122) are respectively separated by a distance, Simultaneous actuation of a slip mechanism 3 and a second slip mechanism 3' and elastic recovery of the two reset members 345 enable the limit portions 343 of the support plates 341 of the two sets of slip mechanisms to be respectively associated with the base 2 The first stopping portion 23 and the second stopping portion 26 are slidably separated, so that the two limiting portions 343 are simultaneously separated from the first blocking portion 23 and the second blocking portion 26, and the overall case is thin. The structure of the structure can provide a limited space for each part to operate. Therefore, in order to reduce the influence of the fine gap and the step difference caused by the offset action of the two limiting portions 343, the guiding surfaces 315 passing through the two sets of sliding mechanisms are respectively taken over. And guiding the two limiting portions 343, and causing the two supporting plate bodies 34 to continuously swing with respect to the two first sliding blocks 32, so that the two supporting plates 341 are respectively offset by an angle, Relying on the support faces 316 of the two sets of sliding mechanisms, and simultaneously pressing the two connecting plates 342 against the first slider A plurality of contact faces are formed on the inclined surface 322 of one end 32 to share the load and uniformly supported, and the laminated structure of the linking plate 35 can be laid flat in the hollow groove 317 to be close to the wall surface of the fixed casing (111, 121) to prevent the support plate. When the 341 is seated, the interference with the interlocking plate 35 occurs. Since the two support plates 341 of the two slip mechanisms are oppositely offset by an angle, an accommodating space 14 is formed to accommodate the intermediate curved portion of the flexible display 13.

因此，本發明具有以下之優點： 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。 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。 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。 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。Therefore, the present invention has the following advantages: 1. The present invention can effectively thin and thin the "compensation folding path mechanism" through the connection relationship and structural features between the first slider, the support plate body, the linkage plate and a gear module. Overall, the use of parts can be further simplified to reduce production costs. And the second connecting portion of the supporting plate body is curved and oscillated relative to the first connecting portion of the first sliding block, thereby generating a free swinging action similar to the shaftless slab, that is, without the physical axis pivoting as in the prior art, Helps reduce the volume and reduce the thickness, so as to facilitate the effect of thinning, so that when the whole is bent, the accommodating space can be accommodated to accommodate the curved intermediate portion of the flexible display, and the flexibility can be achieved when the whole is flattened. The flattened intermediate portion of the display forms a stable support. 2. In the present invention, the first rack and the second rack are respectively meshed through the intermediate gears having different gear ratios, so that the fixed housing connecting the first rack and the movable housing connecting the second rack can form different movements. The speed, to avoid the force of the folding action, causes the flexible display to pull or push, not only can achieve the effect of compensating for the difference of the folding path, and can effectively extend the service life of the flexible display. 3. The present invention provides a reverse force between the fixed housing and the movable housing via the elastic action of the compression spring of a telescopic module, so that the first rack and the second rack can be continuously separated. 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, the present invention is through the hollow space between the two sides of the base, the upper and lower laminated structure of the linkage plate is placed to facilitate the movement, and contribute to the overall thinning of the internal parts of the linkage; and the same base The technical means of the two pivotal points on the shaft and the guide post of the first rack and the long guide groove of the base can be beneficial to stabilize the action of the first rack and the telescopic module.
