Description

雙轉軸結構Double shaft structure

本創作係有關於一種鉸鏈，尤指一種折疊式電子裝置之雙轉軸結構。This work is about a hinge, especially a double-axle structure for a foldable electronic device.

目前常見之可掀蓋式或折疊式的雙螢幕電子設備(例如平板電腦或筆記型電腦)，除了原有之鍵盤輸入單元之外，顯示單元也可以觸控方式進行輸入操作，其二機體之間會藉由一鉸鏈以轉動連接雙螢幕。而現今常使用之雙軸鉸鏈，為了防止二機殼在轉動過程中相互碰撞，大都會存在著一個較大之間距，但若是間距過大，不但在外形上不美觀、整體之體積較大，且容易會有異物或是水氣進入之問題，因此，如何縮短二機體之間距以使兩螢幕更加靠近，實為目前此類型雙軸鉸鏈所欲解決的問題。Currently, common flip-up or foldable dual-screen electronic devices (such as tablet computers or laptops) have a touch-sensitive display unit in addition to the original keyboard input unit. The two bodies are connected to the dual screens by a hinge. In order to prevent the two housings from colliding with each other during rotation, the commonly used double-axis hinges usually have a large distance between them. However, if the distance is too large, it will not only be unsightly in appearance and the overall volume will be larger, but it will also be easy for foreign objects or moisture to enter. Therefore, how to shorten the distance between the two bodies to bring the two screens closer is actually the problem that this type of double-axis hinge is trying to solve.

其中，如專利公告第CN201779129U號之「雙軸連動式樞紐器」所示，即揭示了一種雙軸同動之結構，其主要是由片狀之第二支架與第三支架分別固定齒輪組的兩端，兩支架再分別與第一支架固定，使其一心軸帶動一齒輪轉動一角度時，經由惰齒輪組的傳動，使得另一齒輪連同第二心軸同步轉動所述相同角度，同時經由分別套設第一心軸及第二心軸的扭力組件以增加整體摩擦力，藉以分別補償兩心軸轉動的所需扭力。而專利公告第CN206246511U號之「雙軸同動鉸鏈」則是提供了另一種雙軸同動結構，其主要包括兩個心軸、三個螺旋齒輪、一個容置座和一個連接扣片，其中兩個螺旋齒輪分別同軸設置在兩個心軸上，容置座套設在兩軸之間，其內部具有一容置空間，容置空間供另一螺旋齒輪交錯設置並分別嚙接心軸上之螺旋齒輪，通過傳動使兩軸相對反向轉動；容置座之另一端設有一連接扣片使兩個心軸徑向間隔設置，並能相對周向並穩定地自由轉動；在兩軸端部分別透過若干個蝶形彈片、墊片和螺母，通過鎖緊螺母實現緊配定位的功能，再通過蝶形彈片以提供扭力。Among them, as shown in the "Double-axis linked hub" patent announcement No. CN201779129U, a double-axis synchronous movement structure is disclosed, which is mainly composed of a second plate-shaped bracket and a third plate-shaped bracket to respectively fix the two ends of the gear set, and the two brackets are respectively fixed to the first bracket, so that when one axis drives one gear to rotate an angle, the other gear and the second axis are synchronously rotated at the same angle through the transmission of the idle gear set. At the same time, the torque components are respectively mounted on the first axis and the second axis to increase the overall friction force, so as to compensate for the torque required for the rotation of the two axis. Patent announcement No. CN206246511U "Double-axis co-acting hinge chain" provides another double-axis co-acting structure, which mainly includes two spindles, three spiral gears, a receiving seat and a connecting buckle plate, wherein two spiral gears are coaxially arranged on two spindles, and the receiving seat sleeve is arranged between the two spindles, and has a receiving space inside, and the receiving space is provided for another spiral gear. The wheels are arranged alternately and respectively engage with the spiral gears on the spindles, and the two shafts are driven to rotate in opposite directions relative to each other; a connecting buckle is provided at the other end of the accommodating seat to allow the two spindles to be arranged radially spaced and to rotate freely and stably relative to each other in the circumferential direction; a number of butterfly springs, washers and nuts are respectively passed through the ends of the two shafts, and the function of tight fitting and positioning is realized by locking the nuts, and then the butterfly springs are used to provide torque.

惟，上述之「雙軸連動式轉軸」在安裝於電子裝置內之後，其兩側分別透過片形之第二支架與第三支架夾住齒輪組之結構強度較差，在顯示單元與鍵盤輸入單元相對轉動而產生較大之作用力時，將會造成固定片及壓片被撐開而使齒輪組偏移、或齒輪組之間歪斜而產生間隙，進而降低兩機體之間的同步動作穩定性；或上述之「雙軸同動鉸鏈」在容置座一側之軸桿需設一環溝使連接扣片套合，而環溝會減弱軸桿之結構強度，前述兩者都容易在使用者觸控螢幕時，造成螢幕晃動的情形。再者，當使用彈性元件配合摩擦墊圈或是以若干個蝶形彈片提供扭力時，其整體之結構較為複雜。However, after the above-mentioned "double-axis linkage shaft" is installed in the electronic device, the structural strength of the gear set clamped by the second bracket and the third bracket on both sides is relatively poor. When the display unit and the keyboard input unit rotate relative to each other and generate a large force, the fixed plate and the pressure plate will be pushed apart, causing the gear set to shift. Or the gear sets are skewed and produce gaps, thereby reducing the stability of the synchronous movement between the two bodies; or the above-mentioned "double-axis co-acting hinge" needs to have an annular groove on the shaft on one side of the accommodating seat to allow the connecting buckle to fit, and the annular groove will weaken the structural strength of the shaft. Both of the above are easy to cause the screen to shake when the user touches the screen. In addition, when using elastic elements to cooperate with friction washers or using a number of butterfly springs to provide torque, the overall structure is more complicated.

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，創作人積多年的經驗及不斷的研發改進，遂有本創作之產生。In view of this, in order to provide a structure that is different from the commonly used technology and improve the above-mentioned shortcomings, the creators have accumulated many years of experience and continuous research and development and improvement, thus producing this creation.

中間齒輪組3包括相互齒接之一第一螺旋齒輪31及一第二螺旋齒輪32，第一螺旋齒輪31之軸桿一端樞接第一軸孔76，第二螺旋齒輪32之軸桿一端樞接第二軸孔77，而扭力件6之一側面上具有第三軸孔63及第四軸孔64，供分別定位第一螺旋齒輪31及第二螺旋齒輪32之另一端，藉以讓中間齒輪組3以斜方向樞接定位於框架座2內部的限位空間75之中，防止中間齒輪組3脫出座體7之限位空間75，以減少框架座2之整體體積。藉以使整體之結構簡化，且能讓扭力件6在轉動過程以調整扭力時，可以經由同時連接中間齒輪組3、第一齒形件41及第二齒形件51，減少各個傳動齒輪之間的摩擦損耗，並延長零組件之使用壽命。The intermediate gear set 3 includes a first spiral gear 31 and a second spiral gear 32 which are geared to each other. One end of the shaft of the first spiral gear 31 is pivoted to the first shaft hole 76, and one end of the shaft of the second spiral gear 32 is pivoted to the second shaft hole 77. A third shaft hole 63 and a fourth shaft hole 64 are provided on one side surface of the torque member 6 for positioning the other ends of the first spiral gear 31 and the second spiral gear 32, respectively, so that the intermediate gear set 3 is pivoted and positioned in the limiting space 75 inside the frame seat 2 in an oblique direction, preventing the intermediate gear set 3 from escaping from the limiting space 75 of the seat body 7, so as to reduce the overall volume of the frame seat 2. The overall structure is simplified, and the torque member 6 can be connected to the intermediate gear set 3, the first gear member 41 and the second gear member 51 at the same time during the rotation process to adjust the torque, thereby reducing the friction loss between the transmission gears and extending the service life of the components.

藉此，如圖3、圖5及圖6所示，當使用者由蓋合觸控螢幕之0度打開，再翻轉360度時，經由第一軸桿4、第一齒形件41與第二軸桿5、第二齒形件51之反向轉動，即可讓觸控螢幕與鍵盤輸入單元之背面或柔性屏幕相對疊合；而搭配第一套接部61及第二套接部62分別套接第一軸桿4及第二軸桿5所產生之轉動摩擦扭力，則可以對抗操作觸控螢幕時之施力及平面式電子裝置之重量，進而產生穩定之自由停滯效果，方便使用者操作或觀看平面式電子裝置之螢幕所顯示之影像。Thus, as shown in FIG. 3 , FIG. 5 and FIG. 6 , when the user opens the touch screen from the 0-degree cover and then turns it 360 degrees, the touch screen and the back of the keyboard input unit or the flexible screen can be overlapped relative to each other through the reverse rotation of the first shaft 4, the first toothed member 41 and the second shaft 5, the second toothed member 51; and the rotational friction torque generated by the first sleeve portion 61 and the second sleeve portion 62 sleeved on the first shaft 4 and the second shaft 5 respectively can resist the force applied when operating the touch screen and the weight of the flat electronic device, thereby generating a stable free stop effect, which is convenient for the user to operate or view the image displayed on the screen of the flat electronic device.

圖7為本創作雙轉軸結構1之第二實施例，其與第一實施例不同之處在於：第一C形包覆孔611之開放端面向第二C形包覆孔621之開放端，且第一C形包覆孔611之開放端以一長形通道連通第二C形包覆孔621之開放端且軸向貫穿扭力件6，實施時，長形通道之兩端漸擴，且該長形通道做為槽道65。FIG. 7 is a second embodiment of the dual-axle structure 1 of the present invention, which is different from the first embodiment in that the open end of the first C-shaped enclosing hole 611 faces the open end of the second C-shaped enclosing hole 621, and the open end of the first C-shaped enclosing hole 611 is connected to the open end of the second C-shaped enclosing hole 621 by an elongated channel and axially penetrates the torque member 6. During implementation, the two ends of the elongated channel gradually expand, and the elongated channel serves as a groove 65.

圖8為本創作雙轉軸結構1之第三實施例，其與第一、第二實施例不同之處在於：第一軸桿4之一端同軸延伸一第一直桿部46，供連接扭力件6之第一套接部61，第一直桿部46之外周緣具有軸向剖切之一第一長切面461；第二軸桿5之一端同軸延伸一第二直桿部56，供連接扭力件6之第二套接部62，第二直桿部56之外周緣具有軸向剖切之一第二長切面561；第一C形包覆孔611之一端具有一第一定位面613，第二C形包覆孔621之一端具有一第二定位面623。在蓋合狀態之0度時，第一長切面461對應第一定位面613，第二長切面561干涉連接第二C形包覆孔621。而如圖9所示，在翻轉至360度時，第一長切面461干涉連接第一C形包覆孔611，第二長切面561對應第二定位面623，藉此，在相對翻轉360度之過程中，能定位在預定之角度範圍內，並由於在特定角度時之未產生干涉扭力，則能在釋放第一軸桿4或是第二軸桿5其中之一單軸扭力之狀態下，產生自動落下之效果以節省施力。另，第一C形包覆孔611之開放端面向第二形包覆孔621之開放端，扭力件6之第一C形包覆孔611之開放端延著扭力件6之另一側漸縮以直向連通一第一圓切線孔614，第二C形包覆孔621之開放端延著扭力件6之一側漸縮以直向連通一第二圓切線孔624，同樣可以在分別套接第一軸桿4及第二軸桿5之後，分別產生轉動摩擦扭力。FIG8 is a third embodiment of the double-shaft structure 1 of the present invention, which is different from the first and second embodiments in that: a first straight rod portion 46 is coaxially extended from one end of the first shaft 4 to connect to the first sleeve portion 61 of the torque member 6, and the outer periphery of the first straight rod portion 46 has a first long section 461 of the axial section; a second straight rod portion 56 is coaxially extended from one end of the second shaft 5 to connect to the second sleeve portion 62 of the torque member 6, and the outer periphery of the second straight rod portion 56 has a second long section 561 of the axial section; one end of the first C-shaped covering hole 611 has a first positioning surface 613, and one end of the second C-shaped covering hole 621 has a second positioning surface 623. In the closed state of 0 degrees, the first long section 461 corresponds to the first positioning surface 613, and the second long section 561 interferes with the second C-shaped covering hole 621. As shown in FIG9, when flipped to 360 degrees, the first long section 461 interferes with the first C-shaped covering hole 611, and the second long section 561 corresponds to the second positioning surface 623. In this way, during the relative flipping of 360 degrees, it can be positioned within a predetermined angle range, and since no interference torque is generated at a specific angle, when the uniaxial torque of the first shaft 4 or the second shaft 5 is released, an automatic falling effect can be generated to save force. In addition, the open end of the first C-shaped covering hole 611 faces the open end of the second C-shaped covering hole 621. The open end of the first C-shaped covering hole 611 of the torque member 6 tapers along the other side of the torque member 6 to be straightly connected to a first circular tangent hole 614. The open end of the second C-shaped covering hole 621 tapers along one side of the torque member 6 to be straightly connected to a second circular tangent hole 624. Similarly, after the first shaft 4 and the second shaft 5 are respectively sleeved, rotational friction torque can be generated respectively.

In addition, the first positioning hole 81 is coaxially connected to the first pivot hole 731, the second positioning hole 82 is coaxially connected to the second pivot hole 741, and the two sides of the torque member 6' respectively have a first sleeve portion 61 and a second sleeve portion 62, so that one end of the first shaft 4 passes through the first pivot hole 731, the first positioning hole 81 and the first sleeve portion 61 in sequence, and one end of the second shaft 5 passes through the second pivot hole 741, the second positioning hole 82 and the second sleeve portion 62 in sequence, and then is fixedly connected with a C-shaped ring.

綜上所述，本創作係以一框架座定位四個齒輪，在框架座之一端連接一扭力件，並以框架座及扭力件之兩側分別定位兩個軸桿，藉以使兩個軸桿能同步轉動穩定、降低螢幕之晃動程度，並讓整體之結構簡化以縮小體積，進而降低生產成本。而經由第一、第二軸桿之第一、第二限位部分別卡接第一、第二連接件之第一、第二卡槽，以及第一、第二端封件分別連接固定第一、第二軸桿之第一、第二環溝，則可讓第一、第二軸桿能保持足夠之強度，不但能延長使用壽命，且能使兩個軸桿之轉動更穩定。另，經由將扭力件直接連結在框架座之一側，再以第一、第二端封件分別連接固定，更能在較小之空間內，達到扭力強度之要求。再者，將第一至第三實施例之長形定位板與扭力件一體成型為另一個扭力件結構，不僅能使整體之結構更簡化，以減少零件與組裝之工序，且能有效減少各個傳動齒輪之間的摩擦損耗，以延長產品之使用壽命。In summary, this invention uses a frame seat to position four gears, connects a torque piece at one end of the frame seat, and positions two shafts on both sides of the frame seat and the torque piece, so that the two shafts can rotate synchronously and stably, reduce the shaking degree of the screen, simplify the overall structure to reduce the volume, and further reduce the production cost. The first and second limit parts of the first and second shafts are respectively clamped with the first and second clamping grooves of the first and second connecting parts, and the first and second end seals are respectively connected and fixed to the first and second annular grooves of the first and second shafts, so that the first and second shafts can maintain sufficient strength, which can not only extend the service life, but also make the rotation of the two shafts more stable. In addition, by directly connecting the torque member to one side of the frame seat and then connecting and fixing the first and second end seals respectively, the torque strength requirement can be achieved in a smaller space. Furthermore, the elongated positioning plate and the torque member of the first to third embodiments are integrally formed into another torque member structure, which not only simplifies the overall structure to reduce parts and assembly processes, but also effectively reduces the friction loss between each transmission gear to extend the service life of the product.
