Such as, as shown in Figure 3, shell fragment 35 is bowl-type, and the telescopic shaft portion 11 that its rotating sleeve is located at main shaft 10 is held in the side that driven member 30 deviates from friction member 20.
Pad 40 is circular, and is held on shell fragment 35.Pad 40 is sheathed in the telescopic shaft portion 11 of main shaft 10.Pad 40 for the protection of other element of this hinge structure 100, and stops other element to be subject to larger wearing and tearing.Pad 40 can impel the driven surface 311 of driven member 30 to keep abutting with the rubbing surface 23 of friction member 20.
Please referring again to Fig. 3, the assembly department 63 that support 60 comprises pedestal 61 and extended by this pedestal 61 one end.Pedestal 61 has the first end face 611 and the second relative end face 612.Pedestal 61 comprises the stair-stepping host cavity 613 of this pedestal 61 through, and host cavity 613 connects the first end face 611 and the second end face 612, in order to the telescopic shaft portion 11 of this main shaft 10 accommodating, friction member 20, driven member 30, shell fragment 35 and pad 40.The inwall of host cavity 613 offers hooking part 616 further, and hooking part 616 can coordinate with the engagement portion 33 of driven member 30 and limit driven member 30 and relatively rotate with support 60.Hooking part 616 is rectangular recess.Be appreciated that shape and the quantity of engagement portion 33,616 all can change.This assembly department 63 is planar, which is provided with at least one mounting hole 631.In one embodiment, the quantity of mounting hole 631 is two.Support 60 is coordinated with the body 202 of notebook computer 200 by this mounting hole 631, thus keeps relative with this body 202 and fix.
Snap ring 70 is C shape ring, and such as, it is made up of elastic material, or it has certain elasticity.Snap ring 70 can coordinate with the draw-in groove 111 of main shaft 10 and be arranged on main shaft 10, deviates from the host cavity 613 of support 60 to stop main shaft 10.Be appreciated that snap ring 70 also can be replaced by other snap fit with coordinating of draw-in groove 111, as screw-thread fit, screw thread can be set in the telescopic shaft portion 11 of main shaft 10, nut and screw-thread fit are deviate to stop main shaft 10 in the host cavity 613 of support 60.
During assembling, by the telescopic shaft portion 11 of main shaft 10 successively through friction member 20, driven member 30, shell fragment 35, pad 40 inserting in the host cavity 613 of support 60.Snap ring 70 snaps in the draw-in groove 111 in telescopic shaft portion 11.The flange 131 of main shaft 10 abuts the first end face 611 of support 60 and the plane 25 of friction member 20.Friction member 20 is coordinated with fixture block 133 by fluting 251 with main shaft 10 and limiting friction part 20 and main shaft 10 relatively rotate.The driven surface 311 of driven member 30 abuts the rubbing surface 23 of friction member 20, and in the groove 233 be contained on friction member 20 to make the driven bar 313 in driven surface 311, and the fin 231 on friction member 20 is contained in the engagement groove 313 in driven surface 311.One end of driven member 30 supports the end face of shell fragment 35.Snap ring 70 abuts the second end face 612 of support 60, thus it is as a whole that hinge structure 100 is formed.Be connected with the lid 204 of notebook computer 200 by the fixing part 13 of main shaft 10, the assembly department 63 of support 60 is connected with the body 202 of notebook computer 200, namely installs.
The lid 204 of notebook computer 200 can under external force relative to body 202 folding, namely lid 204 is with dynamic friction piece 20 to rotate relative to driven member 30 by main shaft 10, make the fin 231 on friction member 20 skid off driven slot 315 corresponding on driven member 30 and cross contiguous driven bar 313, thus snap in another driven slot 315.When cancelling external force, fin 231 snaps in corresponding driven slot 315 and makes lid 204 be positioned a certain angle relative to body 202.
Owing to friction member 20 there being multiple fin 231, driven member 30 is provided with multiple driven slot 315, thus each fin 231 can be positioned in multiple driven slot 315, and then location lid 204 is relative to the angle of swing of body 202, makes the use of folding-type electronic device 200 more for convenience.
Hinge structure 100 controls the moment size of lid 204 opening angle by friction member 20, driven member 30, shell fragment 35 and pad 40.The rubbing surface 23 of friction member 20 is sphere with the driven surface 311 of driven member 30, and there is driven bar 313 and driven slot 315, thus make the area of contact between rubbing surface 23 and driven surface 311 larger, effectively frictional force can be improved when not increasing boundary dimension and shell fragment 35 elastic force of hinge structure 100, and then raising friction torque, and lid 204 is firmly rested in predetermined angle.And friction member 20 and the alloying constituent of driven member 30 can make friction member 20 and driven member 30 more wear-resisting, not fragile.
Owing to main shaft 10 being provided with telescopic gauffer portion 1131, after main shaft 10 wears support 60, collapsible drive snap ring 70 pushes against support 60, makes the installation of hinge structure 100 more convenient.In addition, the housing 113 of main shaft 10 accommodates honeycomb Wiring body 115, for the cable in main body 202 provides containing space, is convenient to the wiring of folding-type electronic device 200.And honeycomb Wiring body 115 can also can utilize lubrication honey to absorb the heat of cable by supporting cable.

In the present embodiment, locating piece 80 and follower 90 are made up of alloy, and the mass component of its alloy comprises: aluminium 68-75 part, copper 8-10 part, silicon 6-9 part, magnesium 2-2.5 part, iron 1-1.8 part, manganese 1.5-2 part, titanium 2.5-3.5 part, chromium 1-1.5 part, vanadium 1-1.5 part and bismuth 1-1.5 part.
Refer to Figure 10, such as, the multiple positioning strips 831 ' on locating piece 80 ' are not equally distributed, but are formed with compact district 835 and ravel area 837.Follower only there are 1 or a few servo-actuated bar.
Because Consumer has multiple usual orientation angle when opening folding device 200, such as lid 204 opposing body 202 is positioned the positions such as 90 degree of angular position places or 120 degree of angles.When Consumer's detachable cover 204, when lid 204 drives the servo-actuated bar 93 of follower 90 to slip into the compact district 835 of positioning strip 831 ' by main shaft 10, now lid 204 opposing body 202 is near an angle of 90 degrees, and by follower 93 in the slip at compact district 835 place, make Consumer carry out angle adjustment to lid 204 more easily 90 degree of angles.Such as, the positioning strip 831 ' of ravel area 837 is 3, and the positioning strip 831 ' of compact district 835 is 3.Angle between adjacent two positioning strips 831 ' in ravel area 837 is 85 degree.The height of the positioning strip 831 ' of ravel area 837 increases gradually along the radially outward direction of locating piece 80 ', and the height of the positioning strip 831 ' of compact district 835 reduces gradually along the radially outward direction of locating piece 80 ', can make like this, it is more easy that servo-actuated bar 93 slides in ravel area 837, and it is more difficult to slide in compact district 835, improve positioning accurate accuracy.
Such as, folding-type electronic device of the present invention, other mode of executions as mobile phone also comprise the mutual combination of the respective embodiments described above the mobile phone that formed.
Each technical characteristics of the above embodiment can combine arbitrarily, for making description succinct, the each piece of all possible combination of technical characteristics in above-described embodiment is not all described, but, as long as the combination of these technical characteristicss does not exist contradiction, be all considered to be the scope that this specification is recorded
The above embodiment only have expressed several mode of execution of the present invention, and it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
