Description

切換式雙軸樞紐器與使用其的電子裝置Switch-type dual-axis hub and electronic device using the same

本新型是關於一種雙軸式樞紐器,尤指一種連接一掀蓋式電子裝置之兩座體,並可在所述兩座體相對開合的過程中提供順暢之操作手感的切換式雙軸樞紐器。 The new model relates to a double-shaft hinge device, especially a switch-type double-shaft connecting two bases of a flip-top electronic device, and can provide a smooth operating feeling during the relative opening and closing of the two bases hub.

筆記型電腦、手機、掌上型遊戲機等掀蓋式電子裝置,是現今市面上常見之可便於攜帶的電子裝置,掀蓋式電子裝置主要以一樞紐器來連接兩個座體,使所述兩座體可相對樞轉、開合,而為了有效增加所述兩座體可相對展開的角度,可採用雙軸式樞紐器,所述雙軸式樞紐器大抵具有一第一轉軸與一第二轉軸,第一轉軸與第二轉軸分別連接於所述兩座體。 Laptops, mobile phones, handheld game consoles and other flip-top electronic devices are common and portable electronic devices on the market today. The two bases can be pivoted and opened and closed relative to each other, and in order to effectively increase the relative expansion angle of the two bases, a double-axis hinge can be used, and the double-axis hinge generally has a first rotating shaft and a first rotating shaft. Two rotating shafts, the first rotating shaft and the second rotating shaft are respectively connected to the two bases.

又,其中一種雙軸式樞紐器為同步轉動式,亦即第一轉軸與第二轉軸經由齒輪組相接,當第一轉軸受力而轉動時,可以同步帶動第二轉軸一同轉動;另一種雙軸式樞紐器為切換式,其在第一轉軸受力轉動時,第二轉軸會被鎖定而無法轉動,待第一轉軸轉到預定角度時再切換為第二轉軸能轉動、第一轉軸被鎖定而無法轉動的狀態。 In addition, one of the two-axis hinges is a synchronous rotation type, that is, the first rotating shaft and the second rotating shaft are connected through a gear set, and when the first rotating shaft is forced to rotate, it can synchronously drive the second rotating shaft to rotate together; the other The double-shaft hinge is a switch type. When the first shaft is forced to rotate, the second shaft will be locked and cannot be rotated. When the first shaft rotates to a predetermined angle, it will switch to the second shaft that can rotate and the first shaft to rotate. A state where it is locked and cannot be turned.

其中,當現有技術之切換式雙軸樞紐器從第一轉軸切換為第二轉軸轉動時,原本用來鎖定第二轉軸的傳動片會被第二轉軸推頂而移動至抵靠於第一轉軸,從而限制第一轉軸無法轉動,同樣地,當要從第二轉軸切換為第一轉軸轉動時,也是令第一轉軸推頂傳動片移動至抵靠於第二轉軸。而在上述切換的過程中,傳動片與第一轉軸或第二轉軸碰撞除了會產生異音之外,相互碰撞處還會產生磨耗,長時間使用過後將會影響切換式雙軸樞紐器的鎖定、切 換效果,再者,使用者翻轉座體至切換角度時,也會因為傳動片瞬間解除鎖定而產生卡頓的手感。 Wherein, when the prior art switch-type dual-shaft hinge is switched from the first rotating shaft to the second rotating shaft, the transmission plate originally used to lock the second rotating shaft will be pushed up by the second rotating shaft and move to abut against the first rotating shaft , so that the first shaft cannot be rotated. Similarly, when switching from the second shaft to the rotation of the first shaft, the first shaft pushes the driving piece to move against the second shaft. During the above switching process, the collision between the transmission plate and the first rotating shaft or the second rotating shaft will not only produce abnormal noise, but also wear at the collision place, which will affect the locking of the switching double-shaft hinge after long-term use. ,cut In addition, when the user flips the base body to switch the angle, it will also cause a stuck feel because the transmission plate is instantly unlocked.

如上所述,因此現有技術之切換式雙軸樞紐器仍有待進一步改良。 As mentioned above, the switch-type dual-shaft hinge device of the prior art still needs to be further improved.

有鑑於前述現有技術所存在的問題,本新型的創作目的在於提供一種切換式雙軸樞紐器與使用其的電子裝置,切換式雙軸樞紐器可減少電子裝置之兩座體在相對開合過程中因構件碰撞而產生的異音與磨耗,從而提供順暢的操作手感。 In view of the aforementioned problems in the prior art, the purpose of the invention is to provide a switchable biaxial hinge device and an electronic device using the same.

The pivoting action of a rotating shaft 21 and the second rotating shaft 22 correspondingly switches and controls the locking and pivoting modes of the first switching cam 213 and the second switching cam 223 . Specifically, the switching member 41 is switched to the first switching stop end 2131 of the first switching cam 213 to control the locking of the first rotating shaft 21 while the second rotating shaft 22 is pivoted; the switching member 41 is switched to the second switching cam 223 The second switching stop end 2231 controls the locking of the second rotating shaft 22 while the first rotating shaft 21 pivots. More specifically, the first switching free end 2132 and the second switching free end 2232 of the first switching cam 213 and the second switching cam 223 push against the switching member 41 in sequence, so that the switching member 41 is in the first switching position. The switching cam 213 and the second switching cam 223 move back and forth, and when the switching member 41 moves along the switching free ends 2132 , 2232 of one switching cam 213 , 223 , the switching stop end 2231 of the other switching cam 223 , 213 , 2131 and the switching member 41 are locked with each other and cannot be rotated.

如圖4所示,緩衝彈片42為彈性片體,且設置於第一轉軸21的第一傳動凸輪215和第二轉軸22的第二傳動凸輪225之間,緩衝彈片42之兩端具有對稱之一第一彈性臂421與一第二彈性臂422,第一彈性臂421與第二彈性臂422分別保持抵靠於第一傳動凸輪215與第二傳動凸輪225,緩衝彈片42是根據第一轉軸21與第二轉軸22的樞轉模式,使第一彈性臂421與第二彈性臂422相應控制抵壓第一傳動凸輪215與第二傳動凸輪225的彈性壓縮或彈性釋放程度,藉此在第一轉軸21和第二轉軸22上形成促使第一轉軸21和第二轉軸22轉動的力矩。具體來說,緩衝彈片42根據第一轉軸21與第二轉軸22的樞轉模式,使第一彈性臂421與第二彈性臂422相應控制抵壓第一傳動凸輪215的第一傳動止擋端2151與第一傳動自由端2152、第二傳動凸輪225的第二傳動止擋端2251與第二傳動自由端2252的彈性壓縮或彈性釋放程度。上述緩衝彈片42能以材質或結構來形成所需要的彈性力,也能同時以材質搭配結構來形成所需要的彈性力。 As shown in FIG. 4 , the buffer elastic sheet 42 is an elastic sheet body, and is disposed between the first transmission cam 215 of the first rotating shaft 21 and the second transmission cam 225 of the second rotating shaft 22 . Both ends of the buffer elastic sheet 42 have symmetrical A first elastic arm 421 and a second elastic arm 422, the first elastic arm 421 and the second elastic arm 422 are respectively held against the first transmission cam 215 and the second transmission cam 225, the buffer elastic piece 42 is based on the first rotating shaft 21 and the pivoting mode of the second rotating shaft 22, so that the first elastic arm 421 and the second elastic arm 422 control the degree of elastic compression or elastic release against the first transmission cam 215 and the second transmission cam 225, so that the The first rotating shaft 21 and the second rotating shaft 22 are formed with a moment that drives the first rotating shaft 21 and the second rotating shaft 22 to rotate. Specifically, the buffer elastic sheet 42 controls the first elastic arm 421 and the second elastic arm 422 to press against the first transmission stop end of the first transmission cam 215 according to the pivoting mode of the first rotation shaft 21 and the second rotation shaft 22 . 2151 and the first transmission free end 2152, the second transmission stop end 2251 of the second transmission cam 225 and the second transmission free end 2252 of the elastic compression or elastic release degree. The above-mentioned buffer elastic sheet 42 can form the required elastic force by using the material or structure, and can also form the required elastic force by using the material and the structure at the same time.

第一承架51固接於第一轉軸21之固接部212而可與第一轉軸21一同連動,且第一承架51係用以與前述電子裝置60之第一座體61相互固接,使切換式雙軸樞紐器的第一轉軸21能藉由第一承架51而連接於第一座體61。 The first support frame 51 is fixed on the fixing portion 212 of the first rotating shaft 21 and can be linked with the first rotating shaft 21 , and the first support frame 51 is used for fixing the first base 61 of the electronic device 60 to each other. , so that the first rotating shaft 21 of the switchable biaxial hinge can be connected to the first base 61 through the first bearing frame 51 .

第二承架52固接於第二轉軸22之固接部222而可與第二轉軸22一同連動,且第二承架52係用以與前述電子裝置60之第二座體62相互固接,使切換式雙軸樞紐器的第二轉軸22能藉由第二承架52而連接於第二座體62。 The second support frame 52 is fixed on the fixing portion 222 of the second rotating shaft 22 so as to be able to be linked together with the second rotating shaft 22 , and the second support frame 52 is used for fixing the second base body 62 of the electronic device 60 to each other. , so that the second rotating shaft 22 of the switchable biaxial hinge can be connected to the second base 62 through the second bearing frame 52 .

配合參見圖1、圖3及圖4所示,當電子裝置60之第一座體61與第二座體62呈蓋合狀態時,第一轉軸21之第一切換凸輪213的第一切換自由端2132抵頂於切換件41,第二轉軸22則以第二切換凸輪223上的第二切換止擋端 2231與切換件41相互鎖定,緩衝彈片42的兩端則分別抵頂於第一轉軸21之第一傳動凸輪215和第二轉軸22之第二傳動凸輪225。 Referring to FIG. 1 , FIG. 3 and FIG. 4 , when the first base 61 and the second base 62 of the electronic device 60 are in a covered state, the first switching of the first switching cam 213 of the first rotating shaft 21 is free The end 2132 abuts against the switching member 41 , and the second rotating shaft 22 uses the second switching stop end on the second switching cam 223 The 2231 and the switching member 41 are locked with each other, and the two ends of the buffer elastic sheet 42 abut against the first transmission cam 215 of the first rotating shaft 21 and the second transmission cam 225 of the second rotating shaft 22 respectively.

此時,當使用者開始翻轉第二座體62,由於切換件41能沿第一轉軸21之第一切換凸輪213的第一切換自由端2132移動,故主支座11、輔助支座12和第二轉軸22會一同相對第一轉軸21轉動,而由於第二轉軸22與切換件41相互鎖定,且第一轉軸21的第一切換凸輪213和第二轉軸22的第二切換凸輪223已無空間可供切換件41移動,故第二轉軸22無法相對主支座11和輔助支座12轉動。 At this time, when the user starts to turn over the second base body 62, since the switching member 41 can move along the first switching free end 2132 of the first switching cam 213 of the first rotating shaft 21, the main support 11, the auxiliary support 12 and the The second rotating shaft 22 will rotate relative to the first rotating shaft 21 together. Since the second rotating shaft 22 and the switching member 41 are locked with each other, the first switching cam 213 of the first rotating shaft 21 and the second switching cam 223 of the second rotating shaft 22 have no The space is available for the switching member 41 to move, so the second rotating shaft 22 cannot rotate relative to the main support 11 and the auxiliary support 12 .

進一步參見圖5及圖7所示,直到第一轉軸21之第一切換凸輪213的第一切換止擋端2131朝向切換件41,第一轉軸21之第一切換凸輪213和切換件41之間始形成可供切換件41移動的空間,此時,第二轉軸22能開始進一步相對主支座11和輔助支座12轉動,並以第二轉軸22之第二切換凸輪223的第二切換自由端2232推頂切換件41朝第一轉軸21之第一切換凸輪213移動,直到切換件41移動至第一傳動止擋端2151形成相互鎖定。 5 and FIG. 7 , until the first switching stop end 2131 of the first switching cam 213 of the first rotating shaft 21 faces the switching member 41 , the first switching cam 213 of the first rotating shaft 21 and the switching member 41 are between At this time, the second rotating shaft 22 can start to rotate further relative to the main support 11 and the auxiliary support 12, and the second switching cam 223 of the second rotating shaft 22 can freely switch The end 2232 pushes the switching member 41 to move toward the first switching cam 213 of the first rotating shaft 21 until the switching member 41 moves to the first transmission stop end 2151 to form mutual locking.

進一步參見圖6至圖8所示,在從第一轉軸21轉動切換為第二轉軸22轉動的過程中,緩衝彈片42的第一彈性臂421會根據第一轉軸21的旋轉程度而對第一傳動凸輪215的第一傳動止擋端2151的彈性壓縮量逐漸增加。緩衝彈片42的第二彈性臂422則會根據第二轉軸22的旋轉程度而對第二傳動凸輪225的第二傳動止擋端2251的彈性壓縮量逐漸減少,此時第二彈性臂422是頂抵於第二傳動自由端2252。由上述的彈性變化關係,可得知緩衝彈片42確實會根據第一轉軸21和第二轉軸22之間的相對轉動作動而產生相應緩衝效果,可以降低切換時之卡頓手感的問題,提供順暢的操作手感。由於第一轉軸21和第二轉軸22的轉動受到了緩衝作用,故能有效減少切換件41對第一轉軸21之第一切換凸 輪213和第二轉軸22之第二切換凸輪223的碰撞,從而達到避免碰撞時所產生之異音的效果。 Further referring to FIG. 6 to FIG. 8 , in the process of switching from the rotation of the first rotating shaft 21 to the rotating of the second rotating shaft 22 , the first elastic arm 421 of the buffer elastic sheet 42 will adjust to the first rotating shaft 21 according to the degree of rotation of the first rotating shaft 21 . The elastic compression amount of the first transmission stop end 2151 of the transmission cam 215 gradually increases. The amount of elastic compression of the second elastic arm 422 of the buffer elastic sheet 42 on the second transmission stop end 2251 of the second transmission cam 225 gradually decreases according to the degree of rotation of the second rotating shaft 22 . Abut against the free end 2252 of the second transmission. From the above elastic variation relationship, it can be known that the buffer elastic piece 42 will indeed produce a corresponding buffer effect according to the relative rotation between the first rotating shaft 21 and the second rotating shaft 22, which can reduce the problem of stuck feel during switching and provide smooth operating feel. Since the rotation of the first rotating shaft 21 and the second rotating shaft 22 is buffered, the first switching protrusion of the switching member 41 on the first rotating shaft 21 can be effectively reduced. The collision between the wheel 213 and the second switching cam 223 of the second rotating shaft 22 can avoid the abnormal noise generated during the collision.

Where the socket rod portion 211 of the first rotating shaft 21 is adjacent to the fixing portion 212 thereof, the second switching cam 223 and the second transmission cam 225 of the second rotating shaft 22 are also integrally formed on the socket of the second rotating shaft 22 by integral molding. The rod portion 221 is adjacent to its fixing portion 222 , and the two torsion force generating modules 30 are located on one side adjacent to the auxiliary support 12 and away from the main support 11 .
