參閱圖8A至圖8D，當該旋轉件3受力沿一第一旋轉方向R1(圖中的順時針方向)朝該臨界位置樞轉，該第一樞接部32與該第二樞接部33沿一樞轉路徑S1順著該頂面111往遠離該第一側邊111a的方向樞轉，並受力連動該軸柱部31、該連板部34、該等擋止部35，使該等擋止部35與該等第一擋止面124分離，並使該連板部34連動該第二殼體9(見圖3)的該開合側92相對該第一殼體8開啟。該第一樞接部32與該第二樞接部33同時牽動該彈性件4以該底桿部41及前述第二軸線L2為軸心沿一相反於該第一旋轉方向R1的第二旋轉方向R2(圖中的逆時針方向)旋轉，使該第一彈壓部42與該第二彈壓部43朝該底桿部41迫近，增加該第一彈壓部42與該第二彈壓部43施加於該第一樞接部32與該第二樞接部33的該第一彈力F1(見圖7C)的彈力大小，該第一彈力F1的方向也隨著該第一樞接部32與該第二樞接部33的位置變更而持續變化，但大致均朝向圖中的右上方的方向。需特別說明的是，當該旋轉件3自該第一位置朝該第二位置樞轉小於該預定角度θ而未達該臨界位置，相當於該第一軸線L1(見圖4)、該第二軸線L2(見圖4)、該第一樞接部32及該第二樞接部33四者非共平面，該第一彈力F1的延伸方向通過該轉軸2下方，進而對該旋轉件3產生一恆使該旋轉件3沿該第二旋轉方向R2樞轉返回該第一位置的力矩。也就是說，當該第二殼體9樞轉小於該預定角度θ，該第二殼體9會如前段所述產生自動閉合於該第一殼體8的效果。Referring to FIG. 8A to FIG. 8D, when the rotating member 3 is forced to pivot in a first rotation direction R1 (clockwise direction in the figure) toward the critical position, the first pivoting portion 32 and the second pivoting portion 33 pivoting along a pivoting path S1 along the top surface 111 in a direction away from the first side edge 111a, and mechanically interlocking the shaft post portion 31, the connecting plate portion 34, and the stopping portions 35, so that The blocking portions 35 are separated from the first blocking surfaces 124, and the connecting plate portion 34 is linked to the opening and closing side 92 of the second housing 9 (see FIG. 3) to be opened relative to the first housing 8. . The first pivoting portion 32 and the second pivoting portion 33 simultaneously pull the elastic member 4 with the bottom rod portion 41 and the second axis L2 as an axis and rotate along a second rotation opposite to the first rotation direction R1. The direction R2 (counterclockwise in the drawing) is rotated to bring the first biasing portion 42 and the second biasing portion 43 toward the bottom rod portion 41, and the first biasing portion 42 and the second biasing portion 43 are added to The elastic force of the first elastic portion F1 (see FIG. 7C) of the first pivoting portion 32 and the second pivoting portion 33, and the direction of the first elastic force F1 also follows the first pivoting portion 32 and the first The position of the two pivoting portions 33 changes continuously, but is substantially in the direction of the upper right in the drawing. It should be particularly noted that when the rotating member 3 is pivoted from the first position toward the second position by less than the predetermined angle θ and does not reach the critical position, corresponding to the first axis L1 (see FIG. 4), the first The two axes L2 (see FIG. 4), the first pivoting portion 32 and the second pivoting portion 33 are non-coplanar, and the extending direction of the first elastic force F1 passes under the rotating shaft 2, and the rotating member 3 is further A moment is generated which causes the rotating member 3 to pivot back to the first position in the second rotational direction R2. That is, when the second housing 9 is pivoted less than the predetermined angle θ, the second housing 9 produces an effect of automatically closing the first housing 8 as described in the preceding paragraph.
當該旋轉件3樞轉預定角度θ至該臨界位置，該第一樞接部32與該第二樞接部33朝向該卡合槽111c的最底端，也就是該彈性件4的該底桿部41的所在位置，而牽動該第一彈壓部42與該第二彈壓部43最接近該底桿部41。在該臨界位置時，該第一軸線L1、該第二軸線L2、該第一樞接部32及該第二樞接部33四者共平面，該第一彈壓部42與該第二彈壓部43施加於該第一樞接部32與該第二樞接部33的彈力方向通過該轉軸2，此時該彈性件4所提供的彈力大致上通過該旋轉件3的旋轉軸心(即該第一軸線L1)，所以此狀態下該彈性件4的彈力原則上不構成驅動該旋轉件3旋轉的推力。When the rotating member 3 is pivoted by a predetermined angle θ to the critical position, the first pivoting portion 32 and the second pivoting portion 33 face the bottom end of the engaging groove 111c, that is, the bottom of the elastic member 4 The position of the rod portion 41 is such that the first biasing portion 42 and the second biasing portion 43 are closest to the bottom rod portion 41. In the critical position, the first axis L1, the second axis L2, the first pivoting portion 32 and the second pivoting portion 33 are coplanar, the first elastic portion 42 and the second elastic portion The elastic force applied to the first pivoting portion 32 and the second pivoting portion 33 passes through the rotating shaft 2, and the elastic force provided by the elastic member 4 substantially passes through the rotating shaft of the rotating member 3 (ie, the The first axis L1), so the elastic force of the elastic member 4 in this state does not in principle constitute a thrust for driving the rotation of the rotary member 3.
參閱圖9A至圖9D，及圖10，當該旋轉件3持續樞轉超過該預定角度θ，該第一樞接部32與該第二樞接部33順著該頂面111逐漸靠近該第二側邊111b，該第一彈壓部42與該第二彈壓部43逐漸遠離該底桿部41，且該第一彈壓部42與該第二彈壓部43產生一第二彈力F2施加於該第一樞接部32與該第二樞接部33。該第二彈力F2的方向也隨著該第一樞接部32與該第二樞接部33的位置變更而持續變化，且該第二彈力F2的延伸方向通過該轉軸2上方，進而會對該旋轉件3產生一恆使該旋轉件3沿該第一旋轉方向R1樞轉至該第二位置的力矩。也就是說，當該第二殼體9樞轉超過該預定角度θ，該第二殼體9會產生相對於該第一殼體8自動開啟的效果。Referring to FIG. 9A to FIG. 9D, and FIG. 10, when the rotating member 3 continues to pivot beyond the predetermined angle θ, the first pivoting portion 32 and the second pivoting portion 33 gradually approach the first surface along the top surface 111. The first elastic portion 42 and the second elastic portion 43 are gradually separated from the bottom portion 41, and the first elastic portion 42 and the second elastic portion 43 generate a second elastic force F2 applied to the first side portion 111b. a pivoting portion 32 and the second pivoting portion 33. The direction of the second elastic force F2 also changes continuously as the position of the first pivoting portion 32 and the second pivoting portion 33 changes, and the extending direction of the second elastic force F2 passes over the rotating shaft 2, and The rotary member 3 generates a moment that constantly pivots the rotary member 3 to the second position in the first rotational direction R1. That is, when the second housing 9 pivots beyond the predetermined angle θ, the second housing 9 produces an effect of automatically opening relative to the first housing 8.
當該旋轉件3在該第二位置，該第一樞接部32與該第二樞接部33鄰近該底板部11的該第二側邊111b，該連板部34朝向平行於該底板部11的方向。該彈性件4的該底桿部41抵靠於該卡合槽111c的最底端，該第一彈壓部42與該第二彈壓部43受該第一樞接部32與該第二樞接部33些微壓抵而提供該第二彈力F2施加於該第一樞接部32與該第二樞接部33，該第一樞接部32與該第二樞接部33受力連動該軸柱部31、該連板部34、該等擋止部35，使該等擋止部35緊靠於該等側接合部12的該等第二擋止面125，限制該旋轉件3的旋轉路徑極限，並使該連板部34連動該第二殼體9(見圖3)的該開合側92遠離該第一殼體8，使該第二殼體9相對於該第一殼體8開啟。When the rotating member 3 is in the second position, the first pivoting portion 32 and the second pivoting portion 33 are adjacent to the second side edge 111b of the bottom plate portion 11, the connecting plate portion 34 is oriented parallel to the bottom plate portion. 11 directions. The bottom portion 41 of the elastic member 4 abuts against the bottom end of the engaging groove 111c, and the first elastic portion 42 and the second elastic portion 43 are pivotally connected to the second pivot portion 32. The portion 33 is slightly pressed to provide the second elastic force F2 to be applied to the first pivoting portion 32 and the second pivoting portion 33. The first pivoting portion 32 and the second pivoting portion 33 are forcefully coupled to the shaft. The column portion 31, the connecting plate portion 34, and the blocking portions 35 abut the blocking portions 35 against the second blocking surfaces 125 of the side engaging portions 12 to restrict the rotation of the rotating member 3. a path limit, and the connecting plate portion 34 interlocking the opening and closing side 92 of the second housing 9 (see FIG. 3) away from the first housing 8 such that the second housing 9 is opposite to the first housing 8 is turned on.
當該旋轉件3自該第二位置朝該第一位置的方向樞轉且未抵達該臨界位置，相當於該第一軸線L1(見圖4)、該第二軸線L2(見圖4)、該第一樞接部32及該第二樞接部33四者非共平面，該第二彈力F2的延伸方向通過該轉軸2上方，進而會對該旋轉件3產生恆使該旋轉件3沿該第一旋轉方向R1樞轉回該第二位置的力矩。換句話說，於本實施例中，當該第二殼體9受力朝閉合於該第一殼體8的方向樞轉小於60度(90度-預定角度θ)，該第二殼體9持續受該第二彈力F2推動，使該第二殼體9於解除受力時產生相對於該第一殼體自動開啟的效果。When the rotating member 3 pivots from the second position toward the first position and does not reach the critical position, corresponding to the first axis L1 (see FIG. 4), the second axis L2 (see FIG. 4), The first pivoting portion 32 and the second pivoting portion 33 are non-coplanar, and the extending direction of the second elastic force F2 passes over the rotating shaft 2, thereby further generating the rotating member 3 so that the rotating member 3 is along The first direction of rotation R1 pivots back to the moment of the second position. In other words, in the present embodiment, when the second housing 9 is forced to pivot less than 60 degrees (90 degrees - predetermined angle θ) in a direction closed to the first housing 8, the second housing 9 The second housing 9 is continuously pushed by the second elastic force F2 to produce an effect of automatically opening relative to the first housing when the second housing 9 is released.

When the rotating member 3 is rotated to different angles, the elastic member 4 is synchronously pivoted with the rotating member 3. The elastic force applied to the rotating member 3 causes the elastic force to change direction, causing two different directions of moments, and the rotation of the rotating member 3 can be provided by the arrangement of the elastic member 4 without complicated configuration. The larger cam mechanism can also achieve the effect of automatically opening and closing the second housing 9, so that the purpose of the present invention can be achieved.
