Embodiment

The utility model novelty and other features will be tending towards clear in coordinating the following drawings preferred embodiment to describe in detail.

In diagram possible embodiments, as shown in Figures 1 to 3, the utility model is provided with one first pivot 10 and a second relative pivot 20, described the first pivot 10 and the second pivot 20 connect fixed

plate

11,21 respectively at one end group, for combining respectively upper cover display end and the main machine base that is fixed on electronic equipment (as notebook computer); This first pivot 10 and the second pivot 20 another ends can for socket as relative recessed take turns and cam, elastic device and fixing device jointly to form a required pivot device.

The utility model is separated one first grid spacer 13 and one second grid spacer 14 of setpoint distance relatively in the first described pivot 10 and the second pivot 20 sheathed two, this first grid spacer 13 and the second grid spacer 14 are respectively equipped with the first through hole 131 opposing upper and lower, the 141 and second through

hole

132, 142 for passing respectively the first pivot 10 and the second pivot 20, in this embodiment, the first pivot 10 is through the first relative through

hole

131, 141, the second pivot 20 is through the second relative through

hole

132, 142, simultaneously, the first pivot 10 and the second pivot 20 are made as the section configuration that contains the face of scabbling, the first through hole 131, the 141 and second through

hole

132, 142 is circular port, when the first pivot 10 and the second pivot 20 are rotated, the first grid spacer 13 and the second grid spacer 14 can be along with the first pivot 10 and the second pivot 20 rotations.Meanwhile, between relative first through hole 131,141 of the first grid spacer 13 and the second grid spacer 14 and the second through hole 132,142, be respectively equipped with branched shaft hole 133,143.

In the middle of one, 15 of fulcrums are located between the first grid spacer 13 and the second grid spacer 14, and make two ends 151,152 be articulated in respectively described branched shaft hole 133,143, and a guide screw part 16 that is provided with specific thread is movably set on the axle body of middle fulcrum 15 via its default center hole 161 that is slightly larger than described middle fulcrum 15 axle body diameters.

One the first driving screw 17 that is provided with given length screw thread is located between the first grid spacer 13 and the second grid spacer 14 equally, and be sheathed on through combining interlock on the first pivot 10 axle bodies between the first grid spacer 13 and the second grid spacer 14, and its default thread is moved in succession in the thread of described guide screw part 16; One is provided with and the second driving screw 18 of described the first driving screw 17 reverse threads is located between the first grid spacer 13 and the second grid spacer 14 equally, and be sheathed on through combining interlock on the second pivot 20 axle bodies between the first grid spacer 13 and the second grid spacer 14, and make the same toe joint interlock of its default screw thread in the thread of described guide screw part 16.

In diagram possible embodiments, described reverse thread can be as: when the screw thread of the first driving screw 17 is while being left-handed, the second 18 of driving screws are dextrorotation.Simultaneously, the first driving screw 17 and the second driving screw 18 can be made as the section configuration identical with the first pivot 10 and the second pivot 20 axle bodies (in this embodiment in order to be sheathed on the default central hole 171,181 of the first pivot 10 and the second pivot 20, central hole 171,181 is made as the endoporus that contains the face of scabbling equally), for forming interlock composite structure.In Fig. 5, show above-mentioned the first driving screw 17 and second driving screw 18 with relative reverse thread that be made as, the helix starting point 30 of its whole screw thread all can be used as gear by the travel limits point of use.

As shown in Figures 4 to 6, when the upper cover display end of electronic equipment (as notebook computer) and main machine base closed state (as Fig. 1,3 and Fig. 5) time, in the middle of described, the guide screw part 16 of fulcrum 15 is positioned at axle body one side (this embodiment's left side, during one of them rotation of upper cover display end or main machine base, interlock group is connect to

fixed plate

11,21 and make the first pivot 10 and the second pivot 20 stressed rotations respectively, take that to open electronic equipment upper cover display end be example, the first pivot 10 and its fixed plate 11 synchronous rotaries, make the first driving screw 17 produce the clockwise direction rotation of arrow as shown, described guide screw part 16 is by because of stressed rotation the interlock another side shifting of axle body towards middle fulcrum 15, guide screw part 16 in rotation will synchronously drive the second driving screw 18, the counter clockwise direction rotation that makes the second driving screw 18 produce arrow as shown, whole second pivot 20 is stressed rotates backward, that is to say, as long as the wherein stressed rotation of a pivot, another synchronously rotate in the opposite direction relative to pivot, for example, while applying to electronic equipment (as notebook computer), when upper cover display end one carries out breakdown action, main machine base is that synchronous backward interlock launches, suppose that upper cover display end opens 90 while spending, main machine base is that synchronous backward interlock launches 90 degree, and be jointly launched into 180 degree, same, when one of them constituting parts turnover 180 of electronic equipment is spent, both be folded into folded 360 degree that lean on mutually jointly, become class as the use state of panel computer.

The utility model thereby twin shaft that a kind of improvement is provided are with moving torque pivot device, via synchronous linkage mechanism, can make the Biaxial synchronous start of this type of pivot device, the electronic equipment that makes to adopt this type of dual-axis pivot device rapid and convenient more in running, action is also more stablized smooth and easy.

Above embodiment only, with illustrating for convenience the utility model, is not in a limitative way, and for haveing the knack of this skill personage, complies with various Simple transformeds and the modification that this embodiment can do, and all must include in following claim.
