Description
本創作涉及一種扭力構造,尤其涉及一種雙軸式樞紐裝置。 The present invention relates to a torsion structure, and more particularly to a two-axis hub device.
現有的雙軸式樞紐裝置大部分是採用碟型彈片做為其扭力調整單元,上述碟型彈片需要由人工分別調校其提供給兩個軸桿的扭力,使得兩個軸桿所呈現的扭力值不易準確地被控制,並且使用碟型彈片會使兩個軸桿容易出現彼此不平行的問題。 Most of the existing two-axis pivot devices use a disc-shaped elastic piece as their torque adjustment unit. The above-mentioned disc-shaped elastic piece needs to manually adjust the torsion force provided to the two shafts, so that the torsion force of the two shafts is presented. Values are not easily accurately controlled, and the use of disc-shaped shrapnel makes the two shafts prone to problems that are not parallel to each other.
再者,由於現有雙軸式樞紐裝置需要由人工來調整碟型彈片的壓縮量,因而會使其使用壽命較不穩定。並且碟型彈片所能提供的扭力有其侷限性,難以提供多變化的扭力值,因而不易被應用在具有不同扭力要求的裝置上。 Moreover, since the existing two-axis hinge device needs to manually adjust the compression amount of the disk-shaped elastic piece, the service life thereof is unstable. Moreover, the torque provided by the disc type shrapnel has its limitations, and it is difficult to provide a variable torque value, and thus it is not easy to be applied to devices having different torque requirements.

All aspects of the two-axis pivot device are described one by one. Therefore, only the partial implementation of the above technical features will be described below to illustrate the two-axis pivot device, but the scope of protection of the present invention is not limited thereto.
如圖1及圖2,本創作的第一實施例公開一種雙軸式樞紐裝置100,能被應用在具有不同扭力要求的裝置上,例如:筆記型電腦(圖中未示出)在由閉合狀態開啟時需要低扭力,而當上述筆記型電腦的觸控螢幕與鍵盤呈現一定角度(如:85度~100度)時則是需要高扭力。 1 and 2, a first embodiment of the present disclosure discloses a dual-axis pivot device 100 that can be applied to devices having different torque requirements, such as a notebook computer (not shown) being closed by When the state is turned on, low torque is required, and when the touch screen of the notebook computer and the keyboard are at a certain angle (for example, 85 degrees to 100 degrees), high torque is required.
其中,所述雙軸式樞紐裝置100包含有兩個軸桿1、套設於兩個所述軸桿1的兩個承載座2、位於兩個所述承載座2之間的一齒輪組3、位於兩個所述承載座2的一側(如:圖1中的兩個承載座2左側)且分別套設固定於兩個軸桿1的兩個支架4、位於兩個所述承載座2的另一側(如:圖1中的兩個承載座2右側)且分別穿過兩個軸桿1的多個扭力片5、及位於兩個所述承載座2的另一側(如:圖1中的兩個承載座2右側)且套設於兩個軸桿1末端的一定位件6。 The two-axis pivot device 100 includes two shafts 1 , two bearing seats 2 sleeved on the two shafts 2 , and a gear set 3 between the two bearing blocks 2 . Located on one side of two of the carrier 2 (such as the left sides of the two carriers 2 in FIG. 1 ) and respectively sleeved two brackets 4 fixed to the two shafts 1 and located on the two carriers The other side of 2 (such as the two sides of the two carriers 2 in Figure 1) and the plurality of torsion sheets 5 passing through the two shafts 1 respectively, and the other side of the two of the carriers 2 (e.g. : The two sides of the two carriers 2 in FIG. 1 ) are sleeved on a positioning member 6 at the ends of the two shafts 1 .
如圖3及圖4,兩個所述軸桿1各自定義有一中心軸線C,並且其中一個所述軸桿1的中心軸線C較佳地是平行於另一個所述軸桿1的中心軸線C。再者,兩個所述軸桿1各自具有一扭力段11、一固定段12、及位於所述扭力段11與固定段12之間的一安裝段13。每個所述扭力段11進一步包含有一扭力變化區段111及一扭力恆定區段112。必須說明的是,在本創作未繪示的實施例中,每個所述扭力段11也可僅包含有扭力變化區段111與扭力恆定區段112的其中之一。 3 and 4, each of the two shafts 1 defines a central axis C, and the central axis C of one of the shafts 1 is preferably parallel to the central axis C of the other of the shafts 1. . Furthermore, the two axles 1 each have a torsion section 11 , a fixed section 12 , and a mounting section 13 between the torsion section 11 and the fixed section 12 . Each of the torsion segments 11 further includes a torsion varying section 111 and a torsion constant section 112. It should be noted that in the embodiment not shown in the present creation, each of the torsion segments 11 may also include only one of the torsion change section 111 and the torsion constant section 112.
進一步地說,每個所述扭力變化區段111的外表面具有一非接觸面1111及呈圓弧狀的一接觸面1112,而每個所述扭力恆定區段112大致呈圓柱狀。其中,本實施例的非接觸面1111是以平行上述中心軸線C的軸桿1削平面作說明,但本創作不受限於此。再者,每個所述固定段12的截面大致呈非圓形,而每個所述安裝 段13的中間部分與齒輪組3的一部分(如下所述的兩個主動齒輪31其中一個)為一體成形的構造,但本創作不受限於此。 Further, the outer surface of each of the torsion changing sections 111 has a non-contact surface 1111 and a contact surface 1112 in an arc shape, and each of the torsion constant sections 112 is substantially cylindrical. Here, the non-contact surface 1111 of the present embodiment is described with a plane cut by the shaft 1 parallel to the central axis C, but the creation is not limited thereto. Furthermore, each of the fixed segments 12 has a substantially non-circular cross section, and each of the mountings The intermediate portion of the segment 13 is integrally formed with a portion of the gear train 3 (one of the two drive gears 31 as described below), but the present creation is not limited thereto.
如圖1至圖3,兩個所述承載座2於本實施例中是各由三個片體堆疊組成的結構,且兩個所述承載座2彼此間隔地排列。兩個所述承載座2的相反兩端各貫穿形成有兩個圓孔21,而每個所述承載座2的兩個圓孔21分別套設於兩個軸桿1,並位於兩個安裝段13上。 As shown in FIGS. 1 to 3, the two said carriers 2 are in this embodiment a structure consisting of three stacks of sheets, and the two carriers 2 are arranged at intervals from each other. Two circular holes 21 are formed through the opposite ends of the two bearing bases 2, and the two circular holes 21 of each of the bearing bases 2 are respectively sleeved on the two shafts 1 and are installed in two positions. On segment 13.
所述齒輪組3是位於兩個承載座2之間,也就是說,兩個所述承載座2是分別位於齒輪組3的相反兩側,並且樞接於部分齒輪組3,以限制齒輪組3在中心軸線C方向上的位移。所述齒輪組3於本實施例中包含有兩個主動齒輪31及兩個從動齒輪32。兩個所述主動齒輪31是分別位於兩個安裝段13的中間部位上,較佳地,兩個所述主動齒輪31分別與兩個安裝段13為一體成形的構造。 The gear set 3 is located between the two carriers 2, that is, the two carriers 2 are respectively located on opposite sides of the gear set 3 and are pivotally connected to the partial gear set 3 to limit the gear set. 3 displacement in the direction of the central axis C. The gear set 3 includes two drive gears 31 and two driven gears 32 in this embodiment. The two driving gears 31 are respectively located at intermediate portions of the two mounting sections 13, and preferably, the two driving gears 31 are integrally formed with the two mounting sections 13, respectively.
藉此,當兩個所述軸桿1分別以中心軸線C為軸心自轉時,兩個主動齒輪31能同步自轉,但本創作不受限於此。舉例來說,在本創作未繪示的實施例中,兩個所述主動齒輪31也可以分別與兩個安裝段13為彼此分離的獨立構件,並且兩個所述主動齒輪31各具有一非圓形穿孔,而兩個所述安裝段13各具有與所述非圓形穿孔形狀相對應的一非圓形安裝部,兩個所述非圓形安裝部能分別穿設固定於兩個非圓形穿孔,並且當兩個所述軸桿1分別以其中心軸線C為軸心自轉時,兩個主動齒輪31也能同步自轉。 Thereby, when the two shafts 1 respectively rotate with the central axis C as the axis, the two driving gears 31 can synchronously rotate, but the creation is not limited thereto. For example, in an embodiment not shown in the present creation, the two driving gears 31 may also be separate members from the two mounting segments 13 respectively, and the two driving gears 31 each have a non- a circular perforation, and each of the two mounting segments 13 has a non-circular mounting portion corresponding to the non-circular perforated shape, and the two non-circular mounting portions can be respectively fixed to two non-circular mounting portions. A circular perforation, and when the two shafts 1 respectively rotate with their central axis C as the axis, the two driving gears 31 can also rotate synchronously.
進一步地說,兩個所述從動齒輪32是位於兩個主動齒輪31的內側。而兩個所述從動齒輪32是彼此嚙合且分別嚙合於兩個主動齒輪31。通過上述兩個主動齒輪31及兩個從動齒輪32的彼此連動關係,以使兩個所述軸桿1的其中一個軸桿1能以中心軸線C 為軸心自轉,並通過所述齒輪組3帶動另一個軸桿1朝相反的方向自轉,但本創作不受限於此。舉例來說,在本創作未繪示的實施例中,所述齒輪組3也可僅具有彼此嚙合的兩個主動齒輪31,以使得兩個所述主動齒輪31能通過彼此直接嚙合而互相連動。 Further, the two driven gears 32 are located inside the two driving gears 31. The two driven gears 32 are meshed with each other and meshed with the two driving gears 31, respectively. The two driving gears 31 and the two driven gears 32 are interlocked with each other such that one of the two shafts 1 can be centered on the central axis C. The shaft is rotated and the other shaft 1 is rotated by the gear set 3 in the opposite direction, but the creation is not limited thereto. For example, in an embodiment not shown in the present creation, the gear set 3 may also have only two driving gears 31 that mesh with each other, so that the two driving gears 31 can be interlocked with each other by directly meshing with each other. .

另,每個所述扭力恆定區段112的外表面與中心軸線C的距離(圖未標號)大致等於所述半徑R,以使所述外表面保持抵接於每個扭力片5的相對應外側臂521與相對應扭力調整臂522。 In addition, the distance between the outer surface of each of the torsion constant sections 112 and the central axis C (not labeled) is substantially equal to the radius R, so that the outer surface is maintained in contact with each of the torsion sheets 5 The outer arm 521 and the corresponding torque adjustment arm 522.
進一步地說,於每個所述扭力變化區段111及相對應的任一個扭力單元52中,每個所述扭力調整臂522呈圓弧狀的局部內緣對應於所述中心O的圓心角定義為σ1,所述接觸面1112對應於所述中心軸線C的圓心角定義為σ2,所述非接觸面1111對應於所述中心軸線C的圓心角定義為σ3,並且σ2+σ3=360°,σ1小於σ2,σ1也小於σ3,而σ2較佳是大於σ3,但本創作不受限於此。 Further, in each of the torsion changing sections 111 and the corresponding one of the torsion units 52, a partial inner edge of each of the torsion adjusting arms 522 having an arc shape corresponds to a central angle of the center O Defined as σ1, the central angle of the contact surface 1112 corresponding to the central axis C is defined as σ2, the central angle of the non-contact surface 1111 corresponding to the central axis C is defined as σ3, and σ2+σ3=360° , σ1 is smaller than σ2, σ1 is also smaller than σ3, and σ2 is preferably larger than σ3, but the creation is not limited thereto.
請繼續參閱圖6至圖8,每個所述軸桿1是以其中心軸線C為軸心而相對於每個扭力片5自一第一位置(如:圖6)經過一過渡位置(如:圖7)而朝一第二位置(如:圖8)旋轉(如:圖6至圖8中的逆時針方向旋轉)。其中,每個扭力片5的扭力調整臂522於所述第一位置時未壓迫上述軸桿1的扭力變化區段111(也就是說,扭力調整臂522面向扭力變化區段111的非接觸面1111,並且扭力調整臂522未明顯產生形變),以使扭力變化區段111的接觸面1112與外側臂521摩擦產生一第一扭力F1。如圖7所示,每個扭力片5的扭力調整臂522於所述過渡位置時局部抵接於軸桿1的接觸面1112,以使軸桿1的接觸面1112摩擦外側臂521及部分扭力調整臂522而產生一緩升扭力F3。如圖8所示,每個扭力片5的扭力調整臂522於所述第二位置時完全抵接於軸桿1的接觸面1112,以使軸桿1的接觸面1112摩擦外側臂521及扭力調 整臂522而產生一第二扭力F2。其中,所述第二扭力F2大於所述第一扭力F1,並且所述緩升扭力F3的數值包含自所述第一扭力F1等比率地緩升至所述第二扭力F2的一範圍(如圖9)。 Referring to FIG. 6 to FIG. 8 , each of the shafts 1 has a transitional position from a first position (eg, FIG. 6 ) relative to each of the torsion sheets 5 with its central axis C as an axis (eg, : Fig. 7) and rotates to a second position (e.g., Fig. 8) (e.g., counterclockwise rotation in Figs. 6-8). Wherein, the torsion adjusting arm 522 of each torsion piece 5 does not press the torsion changing section 111 of the shaft 1 in the first position (that is, the non-contact surface of the torsion adjusting arm 522 facing the torsion changing section 111) 1111, and the torsion adjusting arm 522 is not significantly deformed), so that the contact surface 1112 of the torsion changing section 111 rubs against the outer arm 521 to generate a first torsion F1. As shown in FIG. 7 , the torsion adjusting arm 522 of each torsion piece 5 partially abuts the contact surface 1112 of the shaft 1 in the transition position, so that the contact surface 1112 of the shaft 1 rubs the outer arm 521 and part of the torque. The arm 522 is adjusted to generate a gentle lifting torque F3. As shown in FIG. 8, the torsion adjusting arm 522 of each torsion piece 5 completely abuts the contact surface 1112 of the shaft 1 in the second position, so that the contact surface 1112 of the shaft 1 rubs the outer arm 521 and the torque. Tune The whole arm 522 generates a second torsion F2. Wherein the second torsion F2 is greater than the first torsion F1, and the value of the retarding torsion F3 includes a range that is ramped up from the first torsion F1 to the second torsion F2 (eg, Figure 9).
換個角度來說,在每個所述軸桿1及其所穿設的每個扭力片5相對應的扭力單元52中,所述第一位置(如圖6)定義為所述非接觸面1111的部分面向所述扭力調整臂522,並且未面向所述扭力調整臂522的所述非接觸面1111部位對應於中心軸線C的圓心角為σ3-σ1;所述過渡位置是上述軸桿1由第一位置轉動且轉動角度介於σ3-σ1至σ3之間的位置;所述第二位置(如:圖8)則是上述軸桿1由第一位置轉動且轉動角度大於σ3的位置。 In other words, in each of the torsion units 52 corresponding to the shaft 1 and each of the torsion sheets 5 that are disposed, the first position (as shown in FIG. 6) is defined as the non-contact surface 1111. a portion facing the torsion adjusting arm 522, and a portion of the non-contact surface 1111 not facing the torsion adjusting arm 522 corresponding to a central axis C is σ3-σ1; the transition position is that the shaft 1 is The first position is rotated and the rotation angle is between σ3-σ1 and σ3; and the second position (such as FIG. 8) is the position where the shaft 1 is rotated by the first position and the rotation angle is greater than σ3.

Two brackets 4 with the second shaft 1b, on the other side of the two said carriers 2 (such as the two sides of the two carriers 2 in Fig. 10) and each passing through the first shaft 1a and the second a plurality of torsion pieces 5 of the shaft 1b, and the other side of the two of the carriers 2 (such as the right sides of the two carriers 2 in FIG. 10) are sleeved on the ends of the first shaft 1a and the second A positioning member 6 at the end of the shaft 1b.
上述大部分元件的結構及各元件之間的連結關係大致相同於第一實施例。本實施例與第一實施例的不同之處在於齒輪組3的結構設計及齒輪組3與其他元件之間的連結關係。以下將先說明本實施例的齒輪組3的具體構造,而後再適時說明齒輪組3與其他元件之間的連接關係。 The structure of most of the above elements and the connection relationship between the elements are substantially the same as those of the first embodiment. The difference between this embodiment and the first embodiment is the structural design of the gear set 3 and the connection relationship between the gear set 3 and other components. Hereinafter, the specific configuration of the gear train 3 of the present embodiment will be described first, and then the connection relationship between the gear train 3 and other components will be described later.
如圖11及圖12,所述齒輪組3是位於兩個承載座2之間,也 就是說,兩個所述承載座2是分別位於齒輪組3的相反兩側,並且樞接於部分齒輪組3,以限制齒輪組3在中心軸線C、C’方向上的位移。 11 and 12, the gear set 3 is located between the two carriers 2, That is, the two said carriers 2 are respectively located on opposite sides of the gear set 3 and are pivotally connected to the partial gear set 3 to limit the displacement of the gear set 3 in the direction of the central axes C, C'.
請繼續參閱圖12,更詳細地說,所述齒輪組3於本實施例中包含有一第一主動齒輪31a、一第二主動齒輪31b、及一從動齒輪32。所述第一主動齒輪31a位於第一軸桿1a的安裝段13上,所述第二主動齒輪31b位於第二軸桿1b的安裝段13上,且所述第一主動齒輪31a與第二主動齒輪31b彼此呈錯位設置(如圖12中,第一主動齒輪31a是設置於第一軸桿1a安裝段13的左側,而第二主動齒輪31b是設置於第二軸桿1b安裝段13的右側)。較佳地,所述第一主動齒輪31a與第二主動齒輪31b分別與兩個安裝段13為一體成形的構造。 Referring to FIG. 12 in more detail, the gear set 3 includes a first driving gear 31a, a second driving gear 31b, and a driven gear 32 in this embodiment.

The first gear ring 322 and the second gear ring 323 are sequentially disposed at an intermediate portion of the pivot shaft 321 , and the first gear ring 322 is engaged with the first driving gear 31 a ( FIG. 13 ). and The second gear ring 323 is meshed with the second drive gear 31b (Fig. 14). By the above-described interlocking relationship between the first driving gear 31a, the second driving gear 31b, and the driven gear 32, one of the shafts of the first shaft 1a and the second shaft 1b can be centered on the central axis thereof ( C or C') is the shaft rotation, and the other shaft is rotated by the gear set 3 in the same direction.
另,所述從動齒輪32的相反兩端是透過樞接軸321分別樞設於兩個承載座2上,藉此,當所述從動齒輪32被第一主動齒輪31a或第二主動齒輪31b連動時,所述第一齒輪環322與第二齒輪環323能共同沿平行於任一所述中心軸線(C或C’)的一轉軸線L(如:樞接軸321的軸心線)同步自轉,從而避免了軸心偏移的情況發生,但本創作不受限於此。舉例來說,在本創作未繪示的實施例中,當所述從動齒輪32為斜齒輪的結構設計時,所述第一齒輪環322與第二齒輪環323也可以是共同沿垂直於任一所述中心軸線(C或C’)的一轉軸線L同步自轉。 In addition, the opposite ends of the driven gear 32 are respectively pivoted on the two carriers 2 through the pivot shaft 321 , whereby when the driven gear 32 is driven by the first driving gear 31 a or the second driving gear When the 31b is interlocked, the first gear ring 322 and the second gear ring 323 can collectively follow a rotation axis L parallel to any of the central axes (C or C') (eg, the axis of the pivot shaft 321) Synchronous rotation prevents the occurrence of the axis offset, but the creation is not limited to this. For example, in an embodiment not shown in the present writing, when the driven gear 32 is a helical gear design, the first gear ring 322 and the second gear ring 323 may also be perpendicular to each other. A rotation axis L of any of the central axes (C or C') is synchronously rotated.
進一步地說,所述第一主動齒輪31a的齒數除以第一齒輪環322的齒數的比值大於1(如圖13),所述第二主動齒輪31b的齒數除以第二齒輪環323的齒數的比值小於1(如圖14)。較佳地,在本創作的實施例中,所述第一主動齒輪31a的齒數與第一齒輪環322的齒數之間的比例為14比10(如圖13),而所述第二主動齒輪31b的齒數與第二齒輪環323的齒數之間的比例為10比14(如圖14),但本創作不受限於此。 Further, the ratio of the number of teeth of the first driving gear 31a divided by the number of teeth of the first gear ring 322 is greater than 1 (as shown in FIG. 13), and the number of teeth of the second driving gear 31b is divided by the number of teeth of the second gear ring 323. The ratio is less than 1 (Figure 14). Preferably, in the embodiment of the present invention, the ratio between the number of teeth of the first driving gear 31a and the number of teeth of the first gear ring 322 is 14 to 10 (as shown in FIG. 13), and the second driving gear The ratio between the number of teeth of 31b and the number of teeth of the second gear ring 323 is 10 to 14 (Fig. 14), but the present creation is not limited thereto.
如圖15,通過上述各主動齒輪31a、31b的齒數及各齒輪環322、323的齒數之間的比例配置,所述第一軸桿1a能相對於所述基準面P自轉一第一角度α,所述第二軸桿1b能相對於所述基準面P自轉一第二角度β,並且所述第二角度β大於第一角度α。更具體地說,在本創作的實施例中,由於所述第一主動齒輪31a的齒數與第一齒輪環322的齒數之間的比例為14比10,因此當所述第一軸桿1a相對於所述基準面P自轉第一角度α時,所述第一主 動齒輪31a能同步自轉第一角度α,而所述第一主動齒輪31a能使能使嚙合於第一主動齒輪31a的第一齒輪環322自轉一點四倍的第一角度α,並且所述第二齒輪環323能同步於第一齒輪環322自轉一點四倍的第一角度α。再者,由於所述第二主動齒輪31b的齒數與第二齒輪環323的齒數之間的比例為10比14,因此當所述第二齒輪環323自轉一點四倍的第一角度α時,所述第二齒輪環323能使嚙合於第二齒輪環323的第二主動齒輪31b自轉大致兩倍(一點九六倍)的第一角度α,進而使得所述第二軸桿1b能同步地相對於所述基準面P自轉大致兩倍的第一角度α(即第二角度β)。 As shown in FIG. 15, the first shaft 1a can be rotated by a first angle α with respect to the reference plane P by the ratio of the number of teeth of each of the driving gears 31a and 31b and the number of teeth of each of the gear rings 322 and 323. The second shaft 1b can be rotated by a second angle β with respect to the reference plane P, and the second angle β is greater than the first angle α. More specifically, in the embodiment of the present invention, since the ratio between the number of teeth of the first driving gear 31a and the number of teeth of the first gear ring 322 is 14 to 10, when the first shaft 1a is opposed When the reference plane P is rotated by the first angle α, the first main The moving gear 31a can synchronously rotate the first angle α, and the first driving gear 31a can enable the first gear ring 322 that is engaged with the first driving gear 31a to rotate a first four times of the first angle α, and The second gear ring 323 can be synchronized with the first angle α of the first gear ring 322 by a factor of four. Moreover, since the ratio between the number of teeth of the second driving gear 31b and the number of teeth of the second gear ring 323 is 10 to 14, when the second gear ring 323 rotates by a factor of four times the first angle α The second gear ring 323 can rotate the second driving gear 31b of the second gear ring 323 by a first two-fold (one-six-six-fold) first angle α, thereby enabling the second shaft 1b to The first angle α (i.e., the second angle β) is rotated approximately twice as fast as the reference plane P.

藉此,當所述雙軸式樞紐裝置100’使用於平板電腦的腳架(或筆記型電腦)時(圖未繪示),由於雙軸式樞紐裝置100’的旋轉中心在轉動時可以被抬伸,因此當平板電腦由蓋合狀態掀起至展開狀態時,可以避免腳架與機殼之間發生干涉的情形。 Thereby, when the biaxial pivot device 100 ′ is used in a tripod (or notebook computer) of a tablet computer (not shown), since the rotation center of the biaxial pivot device 100 ′ can be rotated when rotated Lifting, so when the tablet is lifted from the closed state to the unfolded state, interference between the stand and the case can be avoided.
