筆記型電腦、遊戲機、電子書、行動電話等電子裝置中常設置鉸鏈結構,以實現其相樞接之二部分可相對轉動。為實現電子裝置相互樞接之二部分之聯動,即當施力使電子裝置之一部分相對另一部分轉動時,樞接該電子裝置之二部分之鉸鏈結構一併驅動電子裝置之另一部分轉動,進而實現二倍之開合速度。A hinge structure is often provided in an electronic device such as a notebook computer, a game machine, an e-book, or a mobile phone, so that the two portions of the pivotal connection can be relatively rotated. In order to realize the linkage of the two parts of the electronic device to each other, that is, when one part of the electronic device is rotated relative to the other part, the hinge structure of the two parts of the electronic device is pivoted to drive another part of the electronic device to rotate, and then Double the speed of opening and closing.
常見之可實現聯動之鉸鏈結構通過依次嚙合之四圓柱直齒輪實現聯動之動作。然,當使用一段時間後,因嚙合時齒輪相互之間之磨損,會出現嚙合松脫等問題,導致傳動精度降低,且傳動不平穩。A common hinge structure that can realize linkage is realized by a four-cylinder spur gear that is sequentially engaged. However, when used for a period of time, due to the wear of the gears when meshing with each other, problems such as loosening of the mesh may occur, resulting in a decrease in transmission accuracy and an unsmooth transmission.
鑒於上述情況,有必要提供一種長時間使用後仍可保證較好之傳動精度及傳動平穩性之鉸鏈結構。In view of the above, it is necessary to provide a hinge structure that can ensure better transmission accuracy and transmission stability after long-term use.

The first connecting member and the second connecting member are sleeved on the pivot shaft and the rotating shaft, and the elastic member is abutted against the large diameter end of the secondary gear.
該鉸鏈結構中,當主齒輪與次齒輪嚙合一段時間並產生磨損後,抵持於次齒輪端部之彈性件頂推次齒輪沿著軸向移動,使齒輪間始終保持無縫隙地嚙合,進而保證較高之傳動精度及傳動平穩性。In the hinge structure, when the main gear meshes with the secondary gear for a period of time and wears, the elastic member pushing the secondary gear at the end of the secondary gear moves along the axial direction, so that the gears are always meshed without gaps.

請再一併參閱圖4,組裝時,將傳動組件30之二轉軸31之變形部311分別插設於第一連接件50之抵持部51之二轉軸孔513內,並將次齒輪33套設於轉軸31上。將軸組件10之樞軸11之變形軸段111依次穿過第一連接件50之抵持部51之樞軸孔511、主齒輪13之中心孔131、第二連接件70之樞軸孔71、加固件90、凸輪15之軸孔1511、凸輪隨動件17之套接孔171及軸套組件19,使軸套組件19之緊固件195與樞軸11之末端之螺紋鎖緊。其中,第一連接件50之抵持部51抵持於樞軸11之第一凸緣113,二次齒輪33相互嚙合且分別與一主齒輪13嚙合。二軸組件10按照同樣之方式與第一連接件50、第二連接件70及加固件90連接,即完成鉸鏈結構100之組裝。Referring to FIG. 4 again, the deformation portion 311 of the two shafts 31 of the transmission assembly 30 is respectively inserted into the two shaft holes 513 of the abutting portion 51 of the first connecting member 50, and the secondary gear 33 is sleeved. It is provided on the rotating shaft 31. The deformation shaft segment 111 of the pivot 11 of the shaft assembly 10 is sequentially passed through the pivot hole 511 of the abutting portion 51 of the first connecting member 50, the center hole 131 of the main gear 13, and the pivot hole 71 of the second connecting member 70. The reinforcing member 90, the shaft hole 1511 of the cam 15, the sleeve hole 171 of the cam follower 17, and the sleeve assembly 19 lock the fastener 195 of the sleeve assembly 19 and the end of the pivot shaft 11. The abutting portion 51 of the first connecting member 50 abuts against the first flange 113 of the pivot shaft 11, and the secondary gears 33 mesh with each other and mesh with a main gear 13 respectively. The two-axis assembly 10 is coupled to the first connector member 50, the second connector member 70, and the reinforcement member 90 in the same manner, that is, the assembly of the hinge structure 100 is completed.
該鉸鏈結構100中,第一連接件50與第二連接件70形成一“凹”字形之容置空間(圖未標),主齒輪13、次齒輪33及彈性件35被夾持於第一連接件50之抵持部51和第二連接件70之間並收容於該容置空間內。凸輪15之卡合部153卡持於加固件90之限位孔911內。In the hinge structure 100, the first connecting member 50 and the second connecting member 70 form a "concave"-shaped receiving space (not shown), and the main gear 13, the secondary gear 33 and the elastic member 35 are clamped to the first The abutting portion 51 of the connecting member 50 and the second connecting member 70 are received in the accommodating space. The engaging portion 153 of the cam 15 is engaged in the limiting hole 911 of the reinforcing member 90.
當電子裝置之蓋體帶動一軸組件10相對另一軸組件10轉動時,其中一主齒輪13將轉矩通過二次齒輪33傳遞到另一主齒輪13,使二主齒輪13沿相反方向轉動,實現電子裝置之蓋體與本體之聯動開合,進而達到二倍之開合速度。轉動過程中,彈性件35始終抵持於次齒輪33之大徑端,從而使次齒輪33與主齒輪13較緊地嚙合。When the cover of the electronic device drives the one shaft assembly 10 to rotate relative to the other shaft assembly 10, one of the main gears 13 transmits torque through the secondary gear 33 to the other main gear 13, causing the two main gears 13 to rotate in opposite directions. The cover of the electronic device and the body are interlocked to open and close, thereby achieving twice the opening and closing speed. During the rotation, the elastic member 35 always abuts against the large diameter end of the secondary gear 33, so that the secondary gear 33 is tightly engaged with the main gear 13.
該鉸鏈結構100中,因彈性件35對次齒輪33施加彈性抵持力,當次齒輪33與主齒輪13之間一旦發生很小之磨損,彈性件35即頂推次齒輪33使其沿軸向移動,使其與主齒輪13始終穩定嚙合,避免次齒輪33與主齒輪13之間產生間隙,進而保證鉸鏈結構100具有較高之傳動精度及傳動平穩性。In the hinge structure 100, since the elastic member 35 applies an elastic abutting force to the secondary gear 33, when there is little wear between the secondary gear 33 and the main gear 13, the elastic member 35 pushes the secondary gear 33 along the shaft. The movement is moved to be stably meshed with the main gear 13 to avoid a gap between the secondary gear 33 and the main gear 13, thereby ensuring high transmission precision and transmission stability of the hinge structure 100.
該鉸鏈結構100中,軸組件10之凸輪隨動件17隨樞軸11相對凸輪15轉動,於轉動過程中,凸輪15之第一凸起1513及第二凸起1515抵持於凸輪隨動件17之不同部位,進而達到改變軸組件10之元件之間之軸向力之目的,並可使鉸鏈結構100於轉動過程中穩定地保持於特定角度。In the hinge structure 100, the cam follower 17 of the shaft assembly 10 rotates with respect to the cam 15 with the pivot shaft 11. During the rotation, the first protrusion 1513 and the second protrusion 1515 of the cam 15 abut against the cam follower The different portions of the 17 further achieve the purpose of changing the axial force between the elements of the shaft assembly 10 and allow the hinge structure 100 to be stably maintained at a particular angle during rotation.
第一連接件50與第二連接件70形成之容置空間可起到一定之防塵作用,進而保證主齒輪13及傳動組件30之正常轉動。The accommodating space formed by the first connecting member 50 and the second connecting member 70 can play a certain dustproof function, thereby ensuring normal rotation of the main gear 13 and the transmission assembly 30.
可以理解,加固件90可省略,而將凸輪15之卡合部153卡於第二連接件70之轉軸孔73內即可。It can be understood that the reinforcing member 90 can be omitted, and the engaging portion 153 of the cam 15 can be engaged in the rotating shaft hole 73 of the second connecting member 70.
樞軸11末端之螺紋可省略,而使用貫穿其末端之插銷將樞軸11上之元件沿軸向鎖緊。The thread at the end of the pivot 11 can be omitted, and the element on the pivot 11 is axially locked using a pin extending through its end.
