On reality was made, first torsion provided the mechanism 14 and second torsion to provide mechanism 15 to dash to moulding with a tinsel, and win contact pin 143 and second contact pin 153 are linked into an integrated entity.
Referring to shown in Figure 7; The first fanning strip 112b both sides of first banking stop 112; When first rotating shaft 11 is rotated, offset with one first spacing salient point 133 wherein respectively, rotate in the first rotation angle θ, 1 scope to limit this first rotating shaft 11; And the first rotation angle θ, 1 scope is loam cake 101 relative base 102 rotations 0 to 180 degree, goes to shown in Figure 2 like Fig. 1.The second fanning strip 122b both sides of second banking stop 122; When second rotating shaft 12 is rotated; Offset with one second spacing salient point 134 wherein respectively; In the second rotation angle θ, 2 scopes, rotate relative to second rotating shaft 12 with restriction bolster sheet 13, and the second rotation angle θ, 2 scopes are loam cake 101 relative base 102 Rotate 180s to 360 degree, go to shown in Figure 3 like Fig. 2.
The loam cake 101 that folding-type electronic device 100 has been described in Fig. 8 A-I forward rotarily opens the action schematic representation.Loam cake 101 and the 0 degree position of base 102 in Fig. 8 A-C, have been shown in positive closure; Loam cake 101 shown in arrow when positive operating position is forward opened; Because the torsion of first rotating shaft 11 is lighter; And the torsion of second rotating shaft 12 is heavier; And can let first rotating shaft 11 rotate earlier forever earlier, first banking stop, the 112 first fanning strip 112b right sides that add first rotating shaft 11 of pivot 1 are butted on the first spacing salient point, 133 positions makes the first axle part 111 forward to rotate, and second banking stop, the 122 second fanning strip 122b right sides of second rotating shaft 12 are butted on the second spacing salient point 134 and make the second axle part 121 not rotate.
The loam cake 101 counter-rotating closing motion schematic representation of folding-type electronic device 100 have been described in Fig. 9 A-I, just in time opposite with Fig. 8.Show at Fig. 9 A-C; Operating position is reverse from the back side for loam cake 101 when closing, because the torsion of second rotating shaft 12 is lighter, and the torsion of first rotating shaft 11 is heavier; And can let bolster sheet 13 rotate earlier forever earlier relative to second rotating shaft 12; Loam cake 101 from 360 degree reverse rotation of dorsal closure to the 180 degree enable possitions that Fig. 9 D-F shows, and then with the first axle part 111 reverse rotation to the positive operating position shown in Fig. 9 G-I, promptly return back to loam cake 101 and the base 102 forwards closure of making shown in Figure 1.
The first axle part 111 of loam cake 101 when unlatching and closure and the torsion variation of the second axle part 121 have been shown among Figure 10.
Forward rotating when opening at loam cake 101, referring to curve shown in the top among the figure, when the positive operating position of 0 degree forward rotates to 180 degree enable possitions, is forward to be rotated by the first axle part 111 to reach at loam cake 101, thus its torsion less be 4kgf-cm; When loam cake 101 forward rotates to 360 degree back side operating positions from 180 degree enable possitions; Be forward to rotate by the second axle part 121 to reach; Because second sleeve 151 and first sleeve, 141 reserved packet are overlying on the second axle part 121, thus when the second axle part 121 forward rotates its torsion 6kgf-cm more greatly on the contrary.
When loam cake 101 reverse rotation are closed, referring to curve shown in the below among Figure 10, during from operating position counter-rotating to 180 degree enable possition, the 360 degree back side, be to reach by the second axle part 121 reverse rotation at loam cake 101, its torsion is less to be 4kgf-cm; When loam cake 101 during from the positive operating position of 180 degree enable possition counter-rotatings to 0 degree, be to reach by the first axle part 111 reverse rotation, its torsion is 6kgf-cm more greatly.
Such design makes that no matter loam cake 101 is forward to rotate to 180 degree enable possitions or during from operating position counter-rotating to 180 degree enable possition, the 360 degree back side, its torsion is all lighter, with the quick breakdown action of convenient user from the positive operating position of 0 degree; In addition, when loam cake 101 forward rotates to 360 degree back side operating positions from 180 degree enable possitions or when the positive operating position of 180 degree enable possition counter-rotatings to 0 degree, its torsion is all heavier, to prevent the collision of loam cake 101 and base 102.
In addition, a plurality of oil duct 111a on the first axle part 111 and the second axle part 121 and 121a make the first axle part 111 and the second axle part 121 relative first sleeves 141 and second sleeve, 151 smooth rotations in order to storing lubricating oil.
To sum up institute is old, and the twin shaft pivot of the easy opening and heavy closing that the utility model provided meets novelty of patent and progressive important document fully, files an application in the whence in accordance with the law.
