See also Fig. 1 to Fig. 2; The utility model provides a kind of tool gear than twin axle pivot device 100; Being arranged at one has in the folding electronic product 200 of a loam cake 201 and a base 202; Can be with reference to shown in Figure 3, so that the function of loam cake 201 relative base 202 rotations, for example folding electronic such as notebook computer, e-book product 200 to be provided.The pivot device 100 of the utility model mainly is made up of one first rotating shaft 11, one second rotating shaft 12, one first torque force device 21, one second torque force device 22, one first fixing frame 31, one second fixing frame 32 and 40 on a gear train structure, and further comprises one first auto-closing wheel, 51,1 second auto-closing wheel 52,1 first limited wheel 61 and one second limited wheel 62.
First rotating shaft 11 of the utility model has a first axle part 111 and one first joint 112, and second rotating shaft 12 has a second axle part 121 and one second joint 122, laterally arranges in the axial direction with this first rotating shaft 11; Second rotating shaft 12 and first rotating shaft 11 laterally arrange in the axial direction.
First torque force device 21 is arranged on the first axle part 111 rotary torsion is provided, and second torque force device 22 is arranged on the second axle part 121 rotary torsion is provided.First torque force device 21 and second torque force device 22 have a plurality of shell fragments 211 and 221 that are socketed on this first axle part 111 and the second axle part 121 respectively, and respectively with a set screw nut 212 and 222 and the first axle part 111 and the second axle part 121 sealed and fixing.
First fixing frame, 31 lock seaming are in loam cake 201, and fixedly sleeved and together rotate with first rotating shaft 11 with first joint 112.Likewise, second fixing frame, 32 lock seaming are in base 202, and fixedly sleeved and together rotate with second rotating shaft 12 with second joint 122.
The main design of the utility model is: as shown in Figure 3 when loam cake 201 relative bases 202 are closed state, the central point line L2 and the horizontal line L 1 of first driving gear 41 and second driving gear 42 are non-perpendicular cant angle theta angle.In addition; A plurality of driven gears 44 make first driving gear 41 and second driving gear 42 produce a reduction speed ratio; Is that the relative base 202 in center is when rotarily opening at loam cake 201 with pivot device 100; First rotating shaft 11 and second rotating shaft 12 have different relative rotation angle, make loam cake 201 in the rotatable unspecified angle location or closed that is opened into.
A plurality of driven gears 44 make first driving gear 41 and second driving gear 42 produce reduction speed ratio, can reach reduction speed ratio with a gearwheel 441a of coaxial setting and the gear ratio of a small gear 441b by a speed change driven gear 441 wherein.
The utility model is because the central point line L2 and the horizontal line L 1 of first driving gear 41 and second driving gear 42 are non-perpendicular cant angle theta angle; Make the support plate 431,432 of gear train structure 40 have respectively one with trapezoidal 431a, the 432a of this cant angle theta angle same tilt degree; Structure by this; The end 201a and the 202a that make loam cake 201 and base 202 that pivot device 100 is installed all are an inclined design; With reference to shown in Figure 3, the visual sense feeling that makes whole folding electronic product 200 outward appearances have reduced volume is to meet folding electronic product 200 consolidations and slimming requirement.
To shown in Figure 6, be the breakdown action figure of the utility model pivot device 100 referring to Fig. 4.In Fig. 4; Loam cake 201 is the closed relatively 0 degree states that are with base 202; The central point line L2 of first driving gear 41 and second driving gear 42 and horizontal line L 1 are non-perpendicular cant angle theta angle (for example being 65 degree); At this moment, loam cake 201 relative bases 202 are started, making first fixing frame 31 is the direction rotation shown in arrow of relative second fixing frame 32 in center with gear train structure 40; To level angle shown in Figure 5 (for example 182 degree); During this action,, make first rotating shaft 11 rotate relative support plate 432 rotation θ angles (for example 65 degree) and make first fixing frame 31 and first driving gear 41 and second driving gear, 42 central point line L2 on same straight line by the reduction speed ratio between first driving gear 41 and second driving gear 42 (for example 1.8); And support plate 432 relative second rotating shaft, 12 rotation level angles deduct θ angle (for example 182-65=117 degree), make loam cake 201 relative bases 202 be opened into level angle and the smooth desktop of ability.Afterwards; It is maximum opening angle (for example 270 degree) that the relative again base 202 of loam cake 201 rotates to vertical angle dorsad as shown in Figure 6; Therebetween; First rotating shaft 11 and second rotating shaft, 12 relative support plates 432 are angle of swing identical with reduction speed ratio (for example first rotating shaft, 11 relative rotations 31 are spent, and second rotating shaft, 12 relative rotations 57 are spent) respectively.
And loam cake 201 will be from maximum opening angle counterrotating closure in 202 last times of base, and then first rotating shaft 11 and second rotating shaft 12 are to reach with the identical different rotation angle respectively of reduction speed ratio.
The person of advancing cooperates shown in Figure 7ly, and first torque force device 21 and second torque force device 22 are oppressed one first auto-closing wheel, 51 and 1 second auto-closing wheel 52 respectively, make loam cake 201 relative bases 202 when closed state, have the auto-closing function.First auto-closing wheel, 51 and second auto-closing wheel 52 contacts with one of them support plate 431 outer side surface, and be respectively equipped with corresponding projection 511,521 and recess 431b on the surface of contact betwixt, 431c, 431d.Projection 511,521 on first auto-closing wheel, 51 and second auto-closing wheel 52 is all a pair of, each to projection 511,521 and central point apart from different, and also corresponding pairs of the recess 431b on the support plate 431,431c, 431d.Loam cake 201 and base 202 are when closed state; First auto-closing is taken turns 51 projections 511 and can be fallen into automatically in the recess 431b on the support plate 431; And the projection 521 on second auto-closing wheel 52 can fall in the recess 431c on the support plate 431 automatically, so when closed state, have the auto-closing function.
In addition, when loam cake 201 relative bases 202 rotated to maximum opening angle, the projection 511 of first auto-closing wheel 51 can fall in the recess 431d on the support plate 431 automatically, also had the auto-closing function when making loam cake 201 rotate to maximum opening angle.
Cooperate shown in Figure 8, respectively fixedly sleeved one first limited wheel 61 and one second limited wheel 62 on the utility model the first axle part 111 and the second axle part 121.First limited wheel 61 and 62 outer side surfaces of second limited wheel at another support plate 432; And have one first sector unit 611 and one second sector unit 621 respectively; First sector unit 611 and second sector unit 621 respectively with another support plate 432 on the one first spacing salient point 432b and the one second spacing salient point 432c interference of evagination, with the maximum opening angle of restriction loam cake 201 relative 202 bases.
More than the graphic a kind of preferred embodiment that is merely the utility model, do not limit the scope of patent protection of the utility model with this.All simple and easy or equivalent variations of being done according to the utility model technological thought, the for example above-mentioned deceleration change of first and second rotating shaft angle of swing when still belongs among the utility model scope of patent protection.
To sum up institute is old, and the tool gear that the utility model provided meets patent novelty and progressive important document fully than twin axle pivot device, files an application in the whence in accordance with the law.
