Embodiment

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

Please refer to Fig. 1 to Fig. 3, the utility model is provided with a support 10, for being combined in electronic equipment one, form end (as system end), described support 10 is provided with a main shaft 11 at a flap 101, and can be in a described main shaft 11 sheathed torque spring 20 sequentially, one fixed Combination is in the pre-compressing tablet 30 of described main shaft 11, one combination interlock in electronic equipment another form end (as display end) and with as described in the rotation bolster 40 of main shaft 11 movable fits, and comprise by both sides friction plate 12 described rotation bolster 40 another ends are sheathed, and relative recessedly take turns 13 and cam 14, the pivot device torque force support structure that elastic device 15 and fixing device 16 form.In this embodiment, recessed take turns 13 and cam 14 be provided with relative recess 131 and lug boss 141(attached ginseng Fig. 4 simultaneously), make described lug boss 141 depart from described recess 131 after arriving set angle and form required set angle location torque force support structure, but the location torque structure that this kind of relative concave forms, only with illustrating for convenience, is not in a limitative way.

In this embodiment, the axle body of described main shaft 11 is provided with two and relatively scabbles face, 30 of described pre-compressing tablets be provided with one with the center hole 31 of described main shaft 11 identical section configurations, and in lamellar body, be provided with the start groove 32 of a preseting length, described start groove 32 contain first interior hold to the greatest extent 321 and another relative second interiorly hold to the greatest extent 322.40 of described rotation bolsters are provided with a round center hole 41 and the movable fit of described main shaft 11, and in a side, be provided with a jack 42 and take turns 13 for recessed described in combination interlocks, in this embodiment, described recessed take turns 13 with eccentric rod 132 grafting interlocks in described jack 42; Described rotation bolster 40 another ends are provided with another connecting hole 43, and for combination interlock, in electronic equipment, another forms end (as display end, figure does not show); Meanwhile, described rotation bolster 40 is being provided with the relative curve bath 44 of a larger width with the described pre-compressing tablet relative radial length of 30 start groove 32 position, and described curve bath 44 contains first inner 441 and second the inner 442.

Described torque spring 20 is located between described support 10 flaps 101 and pre-compressing tablet 30, in this embodiment, described torque spring 20 is provided with the first extending end 21 and another the second relative extending end 22 of side, described the first extending end 21 is pegged graft and be positioned the relative through hole 102 on described support 10 flaps 101, the second 22 of extending ends are stretching into through pre-compressing tablet 30 start grooves 32 in the curve bath 44 of rotation bolster 40, first the inner 441 that makes described the second extending end 22 peg graft and be positioned to rotate bolster 40 curve baths 44 with a precompressed support structures under electronic equipment closed condition.Alleged precompressed support structures refers to that hypothesis torque spring 20 is not completely under stress herein, relative the second extending end 22 of the first described extending end 21 and another side is by respectively with specific direction nature partially extending axially towards torque spring 20, the utility model is pegged graft and is positioned after the through hole 102 on described support 10 flaps 101 at the first described extending end 21, the second extending end 22 originally naturally extending in the another side of torque spring 20 is reversed to an angle (as being torqued into slightly right positions by illustrating slightly leftward position, to form a precompressed torsion), and then first the inner 441 that this second extending end 22 that contains precompressed torsion state is pegged graft and is positioned to rotate bolster 40 curve baths 44.

As shown in Figure 5, when described rotation bolster 40 is closed along with electronic equipment display end (not shown) and in approaching under the level of 0 °, the second extending end 22 of described torque spring 20 passes pre-compressing tablet 30 start grooves 32 with precompressed support structures and stretches into first the inner 441 of rotation bolster 40 curve baths 44, preparing unlocking electronic equipment display end, stirred while raising, described rotation bolster 40 will start along the counterclockwise deflection of direction shown in Fig. 6 arrow, make first the inners 441 of described rotation bolster 40 curve baths 44 synchronously start to leave the second extending end 22 of described torque spring 20, the second extending end 22 that now contains precompressed torsion state will produce counterclockwise deflection power because the elastic restoring force of torque spring 20 own is same, and can be in the situation that not continuing the application of force, electronic equipment display end is automatically springed open to a set angle, in this embodiment, be the first interior terminal of holding to the greatest extent 321 conducts to automatically spring open stroke that sees through pre-compressing tablet 30 start grooves 32, make electronic equipment display end automatically spring open θ angular orientation as shown.

The utility model thereby can be at electronic equipment display end after stirring, and automatically spring open an angle, person easy to use continues whole electronic equipment display end to open and arrives required work angle position, makes the more light power of unlatching, quick and conveniently of this class of electronic devices display end.

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.
