Description

可位移式轉軸及設有該轉軸之可折收裝置Displaceable rotating shaft and foldable device provided with the rotating shaft

本發明是有關可位移式轉軸及設有該轉軸之可折收裝置，尤指一種可隨電子裝置之二局部部位開合而調整二轉軸之間的間距，且於操作過程中使各連動機構保持最小摩擦狀態之轉軸結構。The present invention relates to a displaceable rotating shaft and a foldable device provided with the rotating shaft, and in particular to a rotating shaft structure which can adjust the distance between two rotating shafts as two local parts of an electronic device are opened and closed, and can keep each linkage mechanism in a minimum friction state during operation.

在中華民國專利公開第202221236號發明案中，揭露了一種樞軸模組及電子裝置，其樞軸模組包括：一限位座、一滑動座、至少一連桿組件及一轉軸；該限位座的兩側邊分別設有相互平行的固定板，利用多個鎖固件分別穿設於兩固定板且鎖固在一第一機體的頂面；該滑動座可往復移動地配置於該限位座上；該連桿組件分別連接限位座與滑動座，其中少一連桿組件用以傳輸外力並驅動滑動座產生位移；該轉軸穿設於至少一連桿組件與滑動座且轉軸連接一支架。當第一機體與支架相對移動（展開或閉合）時，支架帶動轉軸相對滑動座旋轉且施力於至少一連桿組件，以帶動該滑動座沿著該限位座移動，使該支架邊緣可相對遠離或接近於該第一機體之散熱區。In the invention case No. 202221236 of the Republic of China, a pivot module and an electronic device are disclosed, wherein the pivot module includes: a limit seat, a sliding seat, at least one connecting rod assembly and a rotating shaft; the two sides of the limit seat are respectively provided with mutually parallel fixed plates, and a plurality of locking pieces are respectively penetrated through the two fixed plates and locked to the top surface of a first body; the sliding seat is reciprocatingly arranged on the limit seat; the connecting rod assembly is respectively connected to the limit seat and the sliding seat, wherein at least one connecting rod assembly is used to transmit external force and drive the sliding seat to generate displacement; the rotating shaft is penetrated through at least one connecting rod assembly and the sliding seat and the rotating shaft is connected to a bracket. When the first body and the bracket move relative to each other (open or close), the bracket drives the shaft to rotate relative to the sliding seat and applies force to at least one connecting rod assembly to drive the sliding seat to move along the limiting seat, so that the edge of the bracket can be relatively far away from or close to the heat dissipation area of the first body.

然而，由該發明案之專利圖式中，可看出其轉軸之延伸部係為圓形斷面，而該連桿組件之第二連桿具有套合於該延伸部之圓孔，因此該轉軸之延伸部明顯不具有驅動該連桿組件之第二連桿轉動的機制，且於其專利說明書中亦未對上述該第二連桿之驅動方式有任何的說明，在應用上，有難以實施的疑慮。However, from the patent drawings of the invention, it can be seen that the extension of the rotating shaft is a circular cross-section, and the second connecting rod of the connecting rod assembly has a circular hole that fits into the extension. Therefore, the extension of the rotating shaft obviously does not have a mechanism to drive the second connecting rod of the connecting rod assembly to rotate, and there is no description of the driving method of the above-mentioned second connecting rod in its patent specification. In terms of application, there are concerns that it is difficult to implement.

再者，於該發明案中並未設置可彈性迫緊該連桿組件及滑動座的相關機構，致使該支架與該第一機體之間的摩擦阻力較小；在實際應用時，該支架不但無法被定位於任何開啟的角度，且再掀起的角度小於90度時，該支架可能會有自動向下蓋合的動作，形成一應用上的缺失。Furthermore, the invention does not provide a mechanism for elastically tightening the connecting rod assembly and the sliding seat, so that the friction resistance between the bracket and the first body is relatively small; in actual application, the bracket cannot be positioned at any opening angle, and when the angle of the bracket is less than 90 degrees, the bracket may automatically close downward, resulting in a lack of application.

在中華民國專利公告第I715198號發明案中，揭露了一種轉軸模組與可攜式電子裝置，其轉軸模組包括：第一支架、第二支架、第一轉軸、樞結件以及連桿，其中第一轉軸設置在組裝於第一機體之第一支架上，樞結件設置在組裝於第二機體之第二支架上；該第一支架具有一立板，於該立板上設有軌道與定位孔；該第一轉軸具有定位部與軸部，該定位部嵌設於該定位孔上形成定位；該連桿包括彼此相對的第一端與第二端，該第一端樞接於該第一轉軸的軸部；該第二支架具有一樞接於該連桿之第二端的延伸部，該延伸部上設有軸孔；該樞結件具有移動部及軸部，該軸部穿設於該軸孔，該移動部係可樞轉地伸入該第一支架的軌道中；此外，該轉軸模組還包括一扭力組件，當該第二支架與樞結件在相對樞轉時，藉由該扭力組件所產生的摩擦力而提供該第二支架與樞結件之間的扭力。In the invention case of Patent Publication No. I715198 of the Republic of China, a shaft module and a portable electronic device are disclosed, wherein the shaft module includes: a first bracket, a second bracket, a first shaft, a hinge and a connecting rod, wherein the first shaft is arranged on the first bracket assembled on the first body, and the hinge is arranged on the second bracket assembled on the second body; the first bracket has a vertical plate, and a track and a positioning hole are arranged on the vertical plate; the first shaft has a positioning portion and a shaft portion, and the positioning portion is embedded in the positioning hole to form a positioning; the connecting rod It includes a first end and a second end opposite to each other, the first end is pivoted to the shaft of the first rotating shaft; the second bracket has an extension portion pivoted to the second end of the connecting rod, and the extension portion is provided with an axial hole; the hinge has a moving portion and an axial portion, the axial portion is inserted into the axial hole, and the moving portion is pivotally extended into the track of the first bracket; in addition, the rotating shaft module also includes a torsion assembly, when the second bracket and the hinge are pivoted relative to each other, the friction force generated by the torsion assembly provides torque between the second bracket and the hinge.

在操作時，當該第一、二機體於折疊收合狀態，該第二支架之延伸部與該連桿處於完全伸展位置，使該樞結件與第一轉軸之間的間距為最大值；而隨著第一機體相對於第二機體樞轉展開，該第二支架之延伸部與該連桿逐漸相對收合；直至該第一、二機體完全展開後，該樞結件靠近該第一轉軸而使兩者間的間距存在最小值；藉由此種轉軸模組形成類似連桿機構，當樞結件隨著第二支架相對於第一支架旋轉時而移近或遠離第一轉軸，可在第一機體相對於第二機體相對旋轉而開合的過程中，避免受限於固定式轉軸或固定間距的轉軸而容易造成機構干涉的情形，使該第一機體能相對於第二機體機體順利地旋轉開合。During operation, when the first and second bodies are in a folded and retracted state, the extension of the second bracket and the connecting rod are in a fully extended position, so that the distance between the hinge and the first shaft is at a maximum; and as the first body pivots and unfolds relative to the second body, the extension of the second bracket and the connecting rod gradually retract relative to each other; until the first and second bodies are fully unfolded, the hinge is close to the first shaft so that the distance between the two is The distance between the two ends of the first and second ends of the first housing can be minimized; by using such a shaft module to form a similar connecting rod mechanism, when the hinge moves closer to or farther from the first shaft as the second bracket rotates relative to the first bracket, the first housing can be opened and closed by rotating relative to the second body, thereby avoiding the situation in which the mechanism interference is easily caused by being limited by a fixed shaft or a shaft with a fixed spacing, so that the first body can be smoothly rotated and opened relative to the second body.

然而，上述此種結構由於該扭力組件之扭力件係直接作用於該樞結件的軸向，因此使該樞結件之抵靠部與該第二支架的延伸部之間會產生較大的摩擦力；此摩擦力不但會造成該第一、二機體展開收合時之阻力，亦會使該第二支架的延伸部產生嚴重磨損，影響整體轉軸模組之使用壽命。However, in the above structure, since the torque member of the torque assembly directly acts on the axial direction of the hinge, a large friction force is generated between the abutment portion of the hinge and the extension portion of the second bracket. This friction force not only causes resistance when the first and second bodies are unfolded and folded, but also causes severe wear to the extension portion of the second bracket, affecting the service life of the entire shaft module.

有鑑於習見在操作過程中可改變間距之轉軸模組結構有上述應用上的缺點，發明人乃針對該些缺點研究改進之道，終於有本發明產生。In view of the above-mentioned application disadvantages of the rotating shaft module structure that can change the spacing during operation, the inventor has studied ways to improve these disadvantages, and finally the present invention is produced.

該連桿組3具有以一端相互樞接之第一連桿31、第二連桿32；該第一連桿31遠離該第二連桿32的一端設有第一外接端31a，該第一外接端31a係可同步轉動地結合於該連動段22，該第二連桿32遠離該第一連桿31的一端設有第二外接端32a，該第二外接端32a樞接於該支撐部11。The connecting rod assembly 3 includes a first connecting rod 31 and a second connecting rod 32 which are pivotally connected to each other at one end; the first connecting rod 31 is provided with a first external end 31a at one end away from the second connecting rod 32, and the first external end 31a is synchronously rotatably connected to the connecting section 22; the second connecting rod 32 is provided with a second external end 32a at one end away from the first connecting rod 31, and the second external end 32a is pivotally connected to the supporting portion 11.

在本實施例中，該第一連桿31於該第一外接端31a設有一與該連動段22具有相同徑向斷面形狀之連動孔311，以該連動孔311套合於該連動段22，可使該第一連桿31能隨該轉軸2轉動而同步樞轉，而該第二連桿32之該第二外接端32a可經由一樞結件321樞接於該樞接孔13。In this embodiment, the first connecting rod 31 is provided with a connecting hole 311 having the same radial cross-sectional shape as the connecting section 22 at the first external end 31a. The connecting hole 311 is fitted into the connecting section 22, so that the first connecting rod 31 can be synchronously pivoted with the rotation of the shaft 2, and the second external end 32a of the second connecting rod 32 can be pivoted to the pivot hole 13 via a pivot piece 321.

再者，該第一連桿31接近該第二連桿32的一端局部設有一擺動缺口312，該擺動缺口312內凸設有一能樞接該第二連桿32一端部之樞接部313（可為一凸軸），於該擺動缺口312一旁側可結合一擋止件33，該擋止件33具有一套合於該連動段22之連動孔331，並能遮蓋該樞接部313，且該擺動缺口312底面至該擋止件33（擺動缺口312頂部邊緣）之間的缺口深度C，大於該第二連桿32位於相互樞接部位之連桿厚度D，使該第二連桿32在樞轉時，不會與該擺動缺口312底面及擋止件33相摩擦。Furthermore, a swing notch 312 is provided at one end of the first connecting rod 31 close to the second connecting rod 32. A pivoting portion 313 (which may be a cam) is provided inside the swing notch 312 to pivotally connect one end of the second connecting rod 32. A stopper 33 may be coupled to one side of the swing notch 312. The stopper 33 has a connecting portion 312 that is fitted to the connecting section 22. The movable hole 331 can cover the pivoting portion 313, and the notch depth C between the bottom surface of the swing notch 312 and the stopper 33 (the top edge of the swing notch 312) is greater than the connecting rod thickness D of the second connecting rod 32 at the mutually pivoting position, so that the second connecting rod 32 will not rub against the bottom surface of the swing notch 312 and the stopper 33 when pivoting.

該導引組件4具有一導桿41，該導桿41一端設有圓形之軸孔411，可樞轉的套合於該連動段22，於該導桿41上設有至少一導引部412（可為一導槽），該導引部412（導槽）可套合一固定於該定位孔12上之導引件413，形成該導桿41相對於該支撐部11相對滑移的導引。The guide assembly 4 has a guide rod 41, and a circular shaft hole 411 is provided at one end of the guide rod 41, which can be rotatably fitted on the connecting section 22. At least one guide portion 412 (which can be a guide groove) is provided on the guide rod 41. The guide portion 412 (guide groove) can be fitted with a guide member 413 fixed on the positioning hole 12 to form a guide for the guide rod 41 to slide relative to the support portion 11.

在一個可行的實施例中，該導引組件4另設有一連動件42，該連動件42具有一可樞套於該連動段22之軸孔421，且該連動件42於朝向該導桿41之一側設有一被連動凸部422，該導桿41上設有一能對應套合該被連動凸部422之連動部414，使該連動件42能與該導桿41連結，且形成同步連動。In a feasible embodiment, the guide assembly 4 is further provided with a connecting piece 42, which has an axial hole 421 that can be pivoted on the connecting section 22, and the connecting piece 42 is provided with a connected protrusion 422 on one side facing the guide rod 41, and the guide rod 41 is provided with a connecting part 414 that can correspond to the connected protrusion 422, so that the connecting piece 42 can be connected to the guide rod 41 and form a synchronous connection.

該扭力組件5係結合於該連動段22上，且位於該導桿41與該連動段22之鎖合端24之間，該扭力組件5之至少局部可隨該轉軸2同步樞轉，而與該導引組件4產生摩擦，以提供該轉軸2之樞轉扭力。The torque assembly 5 is coupled to the connecting section 22 and is located between the guide rod 41 and the locking end 24 of the connecting section 22. At least a portion of the torque assembly 5 can pivot synchronously with the shaft 2 and generate friction with the guide assembly 4 to provide a pivoting torque for the shaft 2.

在本實施例中，該扭力組件5至少係由一彈性組件50組配多數具高摩擦係數之摩擦件51、52、53所組成，於該摩擦件51、52、53上分別設有連動孔511、521、531（具有與該連動段22相同的徑向斷面形狀），可藉該等連動孔511、521、531分別套合於該連動段22形成連動，該彈性組件50係能沿該轉軸2軸向對該等摩擦件51、52、53產生一彈性作用力，以增加該等摩擦件51、52、53 之間及／或該摩擦件51與該導引組件4之間的摩擦力。In this embodiment, the torque assembly 5 is composed of at least one elastic assembly 50 assembled with a plurality of friction members 51, 52, 53 having a high friction coefficient. Linkage holes 511, 521, 531 (having the same radial cross-sectional shape as the linkage section 22) are respectively provided on the friction members 51, 52, 53. The linkage holes 511, 521, 531 can be respectively fitted on the linkage section 22 to form a linkage. The elastic assembly 50 can generate an elastic force on the friction members 51, 52, 53 along the axial direction of the rotation shaft 2 to increase the friction between the friction members 51, 52, 53 and/or between the friction member 51 and the guide assembly 4.

在一個可行的實施例中，該摩擦件51係可設置於該導桿41與連動件42之間，該摩擦件52設置於該連動件42與該彈性組件50之間，而該摩擦件53可設置於該鎖合件241與該彈性組件50之間，使各摩擦件51、52、53隨該轉軸2同步樞轉時，可與該導引組件4及該鎖合件241產生摩擦；且可依需要在該連動件42朝向該摩擦件52之一表側上設有至少一被卡掣部423（可為一凹陷部位或凸出部位），於相鄰之該摩擦件52上設有卡掣部522（可為一凸出部位或凹陷部位），當該摩擦件52隨該轉軸2樞轉至一預設角度時，該卡掣部522能與該被卡掣部423相互抵頂嵌合，使該活動組件B與該固定組件A之間能被定位於一特定的掀起角度。In a feasible embodiment, the friction member 51 can be arranged between the guide rod 41 and the linking member 42, the friction member 52 can be arranged between the linking member 42 and the elastic component 50, and the friction member 53 can be arranged between the locking member 241 and the elastic component 50, so that when the friction members 51, 52, 53 rotate synchronously with the shaft 2, they can generate friction with the guide component 4 and the locking member 241; and when the linking member 42 moves toward the elastic component 50, the friction member 53 can be arranged between the guide rod 41 and the linking member 42. At least one latched portion 423 (which may be a recessed portion or a protruding portion) is provided on one surface of the friction member 52, and a latching portion 522 (which may be a protruding portion or a recessed portion) is provided on the adjacent friction member 52. When the friction member 52 pivots to a preset angle along the rotating shaft 2, the latching portion 522 can abut against and engage with the latched portion 423, so that the movable component B and the fixed component A can be positioned at a specific lifting angle.

請參第３至５圖所示，可知本發明之上述結構於實際操作時，當該活動組件B完全收（蓋）合於該固定組件A上時，該連桿組3的第一連桿31、第二連桿32之間的相連結係處於最小彎折角度，且該導引件413係位於該導引部412中接近左側之一端（如第３圖所示），此時該活動組件B邊緣與該固定組件A邊緣之間的間距(總長度)最小；當該活動組件B相對該固定組件A逐漸樞轉掀起時，該連桿組3之第一連桿31隨該轉軸2轉動，使該第一連桿31、第二連桿32之間的相連結彎折角度逐漸增加，該導引件413逐漸移至該導引部412中段位置（如第４圖所示），此時該活動組件B邊緣與該固定組件A邊緣之間的間距(總長度)逐漸增加；當該活動組件B相對該固定組件A樞轉至完全掀起的位置時，該第一連桿31、第二連桿32之間的相連結彎折角度為最大，該導引件413係位於該導引部412中接近右側之一端（如第５圖所示），此時該活動組件B邊緣與該固定組件A邊緣之間的間距(總長度)為最大，以便於該固定組件A內部運作時產生的熱量對外發散。Please refer to Figures 3 to 5. It can be seen that when the above structure of the present invention is actually operated, when the movable assembly B is completely retracted (covered) on the fixed assembly A, the connection between the first connecting rod 31 and the second connecting rod 32 of the connecting rod assembly 3 is at the minimum bending angle, and the guide member 413 is located at one end of the guide portion 412 close to the left side (as shown in Figure 3). At this time, the distance (total length) between the edge of the movable assembly B and the edge of the fixed assembly A is the smallest; when the movable assembly B is gradually pivoted and lifted relative to the fixed assembly A, the first connecting rod 31 of the connecting rod assembly 3 rotates with the shaft 2, so that the connection between the first connecting rod 31 and the second connecting rod 32 is bent. The bending angle gradually increases, and the guide member 413 gradually moves to the middle position of the guide portion 412 (as shown in FIG. 4). At this time, the distance (total length) between the edge of the movable component B and the edge of the fixed component A gradually increases; when the movable component B pivots to a fully lifted position relative to the fixed component A, the connection bending angle between the first connecting rod 31 and the second connecting rod 32 is the largest, and the guide member 413 is located at one end of the guide portion 412 close to the right side (as shown in FIG. 5). At this time, the distance (total length) between the edge of the movable component B and the edge of the fixed component A is the largest, so that the heat generated during the internal operation of the fixed component A can be dissipated to the outside.

上述結構於實際運作時，由於該扭力組件5之彈性組件50及摩擦件51、52、53係設置於該導引組件4之導桿41接近該鎖合件241（鎖合端24）的一側，因此可於上述部位產生較大的摩擦阻力；而該連桿組3同步連動之第一連桿31、擋止件33可與相鄰的該擋止凸緣21、導桿41之間產生較小的摩擦阻力，因此不但可減少操作時的施力，亦可降低該連桿組3（第一連桿31）與相鄰組件之間的磨損。When the above structure is actually in operation, since the elastic component 50 and the friction components 51, 52, 53 of the torque component 5 are arranged on the side of the guide rod 41 of the guide component 4 close to the locking component 241 (locking end 24), a larger friction resistance can be generated at the above-mentioned position; and the first connecting rod 31 and the stopper 33 synchronously linked with the connecting rod assembly 3 can generate a smaller friction resistance with the adjacent stopper flange 21 and the guide rod 41, so that not only the force applied during operation can be reduced, but also the wear between the connecting rod assembly 3 (the first connecting rod 31) and the adjacent components can be reduced.

再者，由於該第一連桿31具有擺動缺口312之設計，可使該第二連桿32端部不會被該第一連桿31之擺動缺口312底面與擋止件33所夾合，使該第二連桿32於樞轉過程中與相鄰組件具有最小接觸摩擦面積及最低摩擦阻力，可進一步增加整體組件的使用壽命。Furthermore, since the first connecting rod 31 has a swing notch 312, the end of the second connecting rod 32 will not be clamped by the bottom surface of the swing notch 312 of the first connecting rod 31 and the stopper 33, so that the second connecting rod 32 has a minimum contact friction area and the lowest friction resistance with the adjacent components during the pivoting process, which can further increase the service life of the entire component.

綜合以上所述，本發明可位移式轉軸及設有該轉軸之可折收裝置確可達成隨電子裝置之二局部部位開合而調整二轉軸之間的間距，且於操作過程中使各連動機構保持最小摩擦狀態，以提升整體機構使用壽命之功效，實為一具新穎性及進步性之發明，爰依法提出申請發明專利；惟上述說明之內容，僅為本發明之較佳實施例說明，舉凡依本發明之技術手段與範疇所延伸之變化、修飾、改變或等效置換者，亦皆應落入本發明之專利申請範圍內。In summary, the displaceable shaft and the foldable device provided with the shaft of the present invention can achieve the purpose of adjusting the distance between the two shafts as the two parts of the electronic device are opened and closed, and can keep the linkage mechanisms in a state of minimum friction during operation to improve the service life of the overall mechanism.
