Embodiment
Please consult Fig. 1 and Fig. 2 simultaneously, better embodiment housing 100 of the present utility model comprises lid 10, body 20, first torsion spring 30 and second torsion spring 40.Lid 10 articulates with body 20, lid 10 body 20 (figure does not show) rotation around the shaft relatively, and first torsion spring 30 and second torsion spring 40 are fixed in the rotation of thinking lid 10 in the rotating shaft provides power.In the process of body 20 rotations, housing 100 can be in three kinds of states: closed condition is covered on the body 20 fully at this state lower cover 10 at lid 10; Full-gear is opened into maximum opening angle at this state lower cover 10 with respect to body 20; Half-open position, the state between closed condition and full-gear is opened with respect to body 20 but the maximum opening angle of no show at this state lower cover 10.
Please in conjunction with consulting Fig. 3, lid 10 comprises first supporting portion 12 and second supporting portion 14.First, second supporting portion 12,14 is quadrant, and its axis overlaps and is positioned in the rotating shaft of lid 10.Lid 10 forms a locating slot 16, and locating slot 16 closes on second supporting portion 14.First supporting portion 12 and locating slot 16 are respectively applied for location first torsion spring 30 and second torsion spring 40.An end that has sliding-groove 120, the first torsion springs 30 on the edge grain of 12 bottoms, first supporting portion can slide in sliding-groove 120, and first supporting portion 12 has cambered surface 122.Second supporting portion 14 has operative gear 142, and operative gear 142 can be meshed with the gear of body 20 internal fixation to reach the opening speed that slows down lid 10 and to reduce the bump between the lid 10 and body 20 when reaching maximum opening angle.
Please consult Fig. 2 once more, body 20 offers first opening 22, second opening 24 and the 3rd opening 26.This first opening is offered near the rotating shaft of lid 10, and is relative with first supporting portion 12, can allow first supporting portion 12 to pass in this first opening 22 and enter in the body 20.Similar to first opening 22, this second opening 24 is offered near the rotating shaft of lid 10, and is relative with second supporting portion 14, can allow second supporting portion 14 to pass in this second opening 24 and enter in the body 20.The 3rd opening 26 closes on second opening 24, and second torsion spring 40 is extended to the locating slot 16 of lid 10 in the 3rd opening 26.
Fig. 4 to Fig. 6 is illustrated in the relative position relation of the different conditions lower cover 10 and first torsion spring 30 respectively, is used for elaborating the start of Cover opening process first torsion spring 30.
At first, see also Fig. 4, it is the relative position relation of the lid 10 when this housing 100 is in closed condition and first torsion spring 30.Under this state, lid 10 is covered in the surface of body 20 fully, and first torsion spring 30 is relative with second torsion spring 40 acutely to be reversed, and first torsion spring 30 and second torsion spring 40 store a large amount of potential energy.First section 342 of the first spring arm 34 is embedded in the sliding-groove 120, on the cambered surface 122 that second section 344 and the 3rd section 346 is pressed on first supporting portion 12.The point of contact X of the first spring arm 34 and cambered surface 122 roughly is positioned at the intersection of second section 344 and the 3rd section 346.At this moment, the angle between the 3rd section 346 and first sections 342 is greater than angle under no external force effect.Therefore, the 3rd section 346 effect restoring force on the cambered surface 122 of first supporting portion 12, this restoring force basic along lid cambered surface 122 radially to first supporting portion, 12 application of forces.
Secondly, see also Fig. 5, the relative position relation of the lid 10 and first torsion spring 30 when it is in half-open position for this housing 100.Along with lid 10 rotates around its rotating shaft, the first spring arm 34 moves to sliding-groove 120 directions along cambered surface 122 gradually with the point of contact Y position of cambered surface 122.Along with moving of point of contact Y, the 3rd section 346 relative first section 342 deformation angle reduces, and the restoring force that promptly acts on for the 3rd section 346 on the cambered surface 122 of first supporting portion 12 reduces gradually.
At last, see also Fig. 6, the relative position relation of the lid 10 and first torsion spring 30 when it is in full-gear for this housing 100.Reach maximum opening angle along with lid 10 rotates to, the point of contact Z position of the first spring arm 34 and first supporting portion 12 moves in the sliding-groove 120.Variation along with the point of contact Z position of the first spring arm 34 and first supporting portion 12, the 3rd section 346 relative first section 342 deformation angle makes zero gradually, the restoring force of the 3rd section 346 pairs of first supporting portions effect disappears, and is changed to the support force of 34 pairs first supporting portions 12 of the first spring arm.
When this housing 100 is in closed condition, the 3rd section 346 effect one of the first spring arm 34 of first torsion spring 30 is through first supporting portion 12 radially the restoring force (open inhibition power) of point of contact X along lid 10, and this restoring force can make lid 10 remain on closed condition; The 3rd spring arm 44 effect one reaction forces (unlatching active force) of second torsion spring 40 are in lid 10, and the direction of this reaction force is perpendicular to the 3rd spring arm 44, and this reaction force makes lid 10 that the trend of leaving body 20 be arranged.At this moment, the reaction force of the restoring force of first torsion spring 30 and second torsion spring 40 is maximum.When lid 10 leaves body 20 when opening direction moves, the point of contact of the first spring arm 34 of first torsion spring 30 and the cambered surface 122 of first supporting portion 12 moves to point of contact Y along cambered surface from point of contact X, reduce 30 pairs of lids 10 of first torsion spring along with the unlatching active force of 40 pairs of lids 10 of second torsion spring in this process.Move in the process of point of contact Y at point of contact X, first torsion spring 30 and 40 pairs of lids 10 of second torsion spring maintain in the less excursion along the size of making a concerted effort of lid sense of rotation, thereby the unlatching speed of lid 10 remains in the stability range.When the point of contact of the first spring arm 34 and first supporting portion 12 moved in the sliding-groove 120 by cambered surface 122, the unlatching inhibition power of first torsion spring 30 disappeared, and changed into the unlatching active force to first supporting portion 12.At this moment, first torsion spring 30 and second torsion spring, 40 common opening covers 10 are to reach maximum opening angle.When lid 10 reached maximum opening angle, the unlatching active force of second torsion spring 40 was reduced to minimum, and this moment, first torsion spring 30 also provided the unlatching active force, and this two power acting in conjunction is stablized lid 10 and remained on maximum opening angle.
The pass closed procedure of lid 10 is the inverse process of above-mentioned opening process, does not give unnecessary details at this.
Obviously, under the acting in conjunction of first torsion spring 30 and second torsion spring 40, can make the unlatching speed of lid 10 remain in the stability range substantially, and can make lid 10 keep maximum opening angle.Because lid 10 arrives maximum opening angle with steady rate, can not cause strong bump to body 20, thereby avoid rocking of lid 10.The fit adjustment of the different phase that first torsion spring 30 and second torsion spring 40 are opened at lid 10 acts on the torsion of lid, effectively solves the existing deficiency of traditional torsion spring, produces significant good effect at aspects such as opening speed, working life.
Above-mentioned housing 100 can be widely used in various device, and as gaming machine, portable optic disk player etc., even toolbox, cosmetic container etc. all can be used.
