Embodiment
Embodiment, is shown in shown in Fig. 1 to Fig. 6, and the invention discloses a kind of twin shaft with dynamic pivot device, this twin shaft comprises one first transmission shaft 1, second driving shaft 2, support body 3 and a torsion sleeve 4 with dynamic pivot device.
Concretely:
This first transmission shaft 1 has one first axostylus axostyle 11,1 first assembly part 12, and a first drive portion 13 between this first axostylus axostyle 11 and this first assembly part 12.This second driving shaft 2 also has one second axostylus axostyle 21,1 second assembly part 22, and a second drive portion 23 between this second axostylus axostyle 21 and this second assembly part 22.
This support body 3 has respectively for one first axis hole 31 and one second axis hole 32 that this first axostylus axostyle 11 and this second axostylus axostyle 21 wear, and one also rotarily drives by this first drive portion 13 or this second drive portion 23 driving component 33 rotated with transmission another one between this first drive portion 13 and this second drive portion 23.
This torsion sleeve 4 has one first department of assembly 41 and one second department of assembly 42 respectively in relative two outsides, this first department of assembly 41 has two and is oppositely arranged and the first mutually isometric curved boom 411, and be formed between these two the first curved booms 411 for this first axostylus axostyle 11 wear wherein and by these two first curved booms 411 act on the first assembly space 412, and this second department of assembly 42 has two is oppositely arranged and the second mutually isometric curved boom 421, and be formed between these two the second curved booms 421 for this second axostylus axostyle 21 wear wherein and by these two second curved booms 421 act on the second assembly space 422.
This double-axis hinge can be applicable to assembling between the screen of the cover-lifting type electronic devices such as notebook computer, clamshell phone phone or E-book reader and base.Namely, this first assembly part 12 and this second assembly part 22 by screw locking, rivet etc. arbitrarily means of fixation assemble with a first substrate 5 and a second substrate 6 respectively, this first substrate 5 and this second substrate 6 are then connected with the screen of a cover-lifting type electronic device (not shown) and base respectively.When user carries out relative unlatching or closing motion to this screen and this base, this first substrate 5 can drive this first transmission shaft 1 to rotate, or this second substrate 6 will drive this second driving shaft 2 to rotate, this driving component 3 can be rotated by this first drive portion 13 or this second drive portion 23 rotate with another one in this first drive portion 13 of transmission or this second drive portion 23, and then make this screen and this base present corresponding synchronous on-off action.
Optimize:
This first drive portion 13 is one is the first spiral gear of axle center winding with this first axostylus axostyle 11, and this second drive portion 23 is one is the second spiral gear of axle center winding with this second axostylus axostyle 21, and this driving component 33 is a drving sprial gear coordinated with this first spiral gear and this second spiral gear, and when this first axostylus axostyle 11 or this second axostylus axostyle 21 rotate, by the spinning movement of this first spiral gear of this drving sprial gear synchronous and this second spiral gear.
This twin shaft also includes one with dynamic pivot device and is located at locating piece 7 on this support body 3.This locating piece 7 has one first perforation 71 and one second perforation 72 worn respectively for this first axostylus axostyle 11 and this second axostylus axostyle 21.Like this, jointly limit this torsion sleeve 4 by this locating piece 7 and this support body 3, produce slippage when this first axostylus axostyle 11 and this second axostylus axostyle 21 rotate to prevent this torsion sleeve 4 and then cause the instability of torsion to export.
So, when this first transmission shaft 1 and this second driving shaft 2 rotate, this first axostylus axostyle 11 and this second axostylus axostyle 21 by respectively with these two the first curved booms 411 inside and rub to have produced torsion inside these two the second curved booms 421.Because this first department of assembly 41 and this second department of assembly 42 have two mutually isometric the first curved booms 411 and two the second curved booms 421 respectively, therefore make this first axostylus axostyle 11 all can rub with these two the first curved booms 411 towards either direction rotation and produce the torsion of formed objects, and this second axostylus axostyle 21 rotates towards either direction and also can rub with these two the second curved booms 421 and produce the torsion of formed objects, thus solve screen and base because of be connected with conventional double-axis hinge cause easy opening and heavy closing or open the light problem in series of fortified passes.
Continue to optimize:
This first department of assembly 41 has one and to be defined by these two the first curved boom 411 ends and formed and the first opening 413 be communicated with this first assembly space 412, and this second department of assembly 42 also has one and to be defined by these two the second curved boom 421 ends and formed and the second opening 423 be communicated with this second assembly space 422, and this first opening 413 is arranged in this torsion sleeve 4 each other in the opposite direction with this second opening 423.
This torsion sleeve 4 has a joint 43 between this first department of assembly 41 and this second department of assembly 42, and this joint 43 is being that two vertical sides are respectively a curved surface 431 relative to this first department of assembly 41 and this second department of assembly 42.More excellent, these two curved surfaces 431 are bent towards another side surface direction by one of them side respectively.
This first axostylus axostyle 11 has the first inserted part 111 that is positioned at this first assembly part 12 side relatively, and one is assemblied in this first inserted part 111 to provide the first torsion portion 112 of torsion to this first transmission shaft 1.This second axostylus axostyle 21 has the second inserted part 211 that is positioned at this second assembly part 22 side relatively, and one is assemblied in this second inserted part 211 to provide the second torsion portion 212 of torsion to this second driving shaft 2.Wherein, this first inserted part 111 is one first jack-post, and be surrounded with one first outside thread in this first jack-post outer surface, and this second inserted part 211 is one second jack-post, and be surrounded with one second outside thread in this second jack-post outer surface, and the outer surface of this first jack-post and this second jack-post all has the locating face of the arbitrary shape such as plane or curved surface, and this first torsion portion 112 be multiple be located on this first inserted part 111 the first packing ring and interlocking in this first outside thread those first packing rings to be limited to the first locking nut of this first inserted part 111, and the second packing ring that this second torsion portion 212 is also located on this second inserted part 211 for multiple and interlocking in this second outside thread those second packing rings to be limited to the second locking nut of this second inserted part 211.Wherein, those first packing rings are formed by multiple first elastic washer and two the first space washers laying respectively at two relative outsides of those first elastic washers, those first elastic washers have circular perforations, and these two first space washers all have the perforation coordinating this first jack-post shape, and those second packing rings are formed by multiple second elastic washer and two the second space washers laying respectively at two relative outsides of those second elastic washers, those second elastic washers have circular perforations, and these two second space washers all have the perforation coordinating this second jack-post shape.
