Description

Twin shaft torque pivot device lazy-tongs

Technical field

The utility model is about a kind of twin shaft torque pivot device lazy-tongs, espespecially can be with the member of more simplifying, and unlatching and closed action while making the Biaxial synchronous of this type of torque pivot device carry out set angle or distortion.

Background technique

The class of electronic devices of notebook computer of take is example, contain haply the LCD screen end (upper cover) that a host computer system end (main frame) and can Gong be raised, both connect with pivot device at an opposed end, for take in use the LCD screen that this pivot device raises upper cover as action axle center, operate, or oppositely that both are relatively closed when not using.

For convenience of display screens upper cover being opened to fixed point angle and whole notebook computer turnover being deformed into dull and stereotyped aspect, existing notebook computer mostly adopts twin shaft torque pivot device to carry out the principal organ of opening angle location and wide-angle turnover.

The structure of existing twin shaft torque pivot device is mainly to have one first rotating shaft and upper cover display screens together rotates, and one second rotating shaft and host computer system end together rotate.But existing this type of used the pivot device of twin axle opening compared with wide-angle, in the time of maybe will making the state that changes mutually of 360 ° of display end and system end distortion turnovers, conventionally first make a wherein axle rotate to after special angle, switch to again another axle rotation, except the synchronous turnover mechanism of whole display end and system end quite complicated, more bothersome on manufacturing and assembling, outside cost is higher, the turnover of display end and system end is moved slowly upper and is had some setbacks, simultaneously, user is carrying out 360 ° of mutual repeatedly turnover actions or with same counteragent, is replying in the operation of closed condition, a wherein axle that must see through twin shaft turns to after a set angle, another axle by twin shaft rotates control again, comparatively trouble is with inconvenient.

Model utility content

The purpose of this utility model a kind of twin shaft torque pivot device lazy-tongs are provided, can cross the member of more simplifying, and makes twin shaft torque pivot device carry out set angle position that twin shaft will open or the synchronization motion of distortion.

For reaching above object, the utility model discloses a kind of twin shaft torque pivot device lazy-tongs, it is characterized in that comprising:

One first pivot and a second relative pivot, described the first pivot and the second pivot connect fixed plate to combine respectively upper cover display end and the host computer system end that is fixed on an electronic equipment respectively at one end group; Described the first pivot and the second pivot another end are sequentially socketed relative recessed wheel and cam, elastic device and fixing device;

The first described pivot and the second pivot are slidingly connected and two relatively separate one first grid spacer and one second grid spacers of setpoint distances, and described the first grid spacer and the second grid spacer are respectively equipped with relative branched shaft hole between described the first pivot and the second pivot;

Between described the first grid spacer and the second grid spacer, be provided with two relative driving screws, described driving screw is respectively equipped with and coordinates the through hole of described the first pivot and the second pivot section configuration for moving in succession with described the first pivot and the second pivot group, and on the shaft of described driving screw, is provided with the spiral chute matching;

One fulcrum, is positioned the relative branched shaft hole of described the first grid spacer and the second grid spacer, and on the axle body of described fulcrum a sheathed upper and lower end respectively interlock in the spiral fluted guide wheel of described relative driving screw.

Wherein, described guide wheel upper and lower end be made as that group connects and interlock in the spiral fluted arc subulate of described driving screw.

Pass through said structure, the utility model can see through relative driving screw and a middle guide wheel, make two synchronously starts of relative pivot of this type of twin shaft torque pivot device, the class of electronic devices of notebook computer is in opening procedure, all unlatchings or closing motion carry out synchronous rotary by guide wheel in the middle of described relative driving screw and, the switching process of electronic equipment is more quick and smooth, can more effectively simplify the correlating transforms mechanism between twin shaft simultaneously.

Embodiment

As shown in Figures 1 and 2, in diagram possible embodiments, 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 host computer system end that is fixed on electronic equipment (as notebook computer); Described the first pivot 10 and the second pivot 20 another ends can sequentially be socketed as relative recessed take turns and the member such as cam, elastic device and fixing device jointly to form a required electronic equipment twin shaft torque pivot device.

The first described pivot 10 and the second pivot 20 sheathed two are separated one first grid spacer 30 and one second grid spacer 40 of setpoint distance relatively, described the first grid spacer 30 and the second grid spacer 40 are respectively equipped with the first through hole 31 opposing upper and lower, the 41 and second through hole 32, 42 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 31, 41, the second pivot 20 is through the second relative through hole 32, 42, 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 31, the 41 and second through hole 32, 42 is circular port, when the first pivot 10 and the second pivot 20 are rotated, can interlock the first grid spacer 30 and the second grid spacer 40.Meanwhile, between relative first through hole 31,41 of the first grid spacer 30 and the second grid spacer 40 and the second through hole 32,42, be respectively equipped with relative branched shaft hole 33,43.

The utility model main feature is to be provided with between described the first grid spacer 30 and the second grid spacer 40 two

relative driving screws

50,60, described

driving screw

50,60 is respectively equipped with and coordinates 20 groups, through hole 51,61 that described the first pivot 10 and the second pivot 20 scabble face section configuration and described the first pivot 10 and the second pivot to move in succession, and on shaft, is provided with the

spiral chute

52,62 matching.One 70 of fulcrums are positioned described relative branched shaft hole 33,43, and on the axle body of described fulcrum 70 a sheathed guide wheel 80, make described guide wheel 80 upper and lower end can distinguish interlock in the attached ginseng Fig. 3 of spiral chute 52, the 62(of described driving

screw

50,60).In this preferred embodiment, described guide wheel 80 upper and lower end be made as that arc subulate group connects and interlock in the

spiral chute

52,62 of described

driving screw

50,60.

As shown in Figure 4, when described the first pivot 10 and the second pivot 20 be subject to notebook computer wherein a upper cover display end and/or host computer system end with arrow A or arrow B direction, raise while opening interlock rotation, the first pivot 10 in rotation and/or the second pivot 20 will force because of spinning movement described guide wheel 80 at the axle body of described fulcrum 70, to produce axial reciprocating displacement along arrow C direction.That is when wherein a pivot (as the first pivot 10) rotates, another pivot (as the second pivot 20) will rotate along with synchronous backward.
