elastic components

40 and 60, sleeve pipe 50, block 70 and all sheathed axis 20 of button 80 and be assembled into one, and pass through scyewed joint between axis 20 and the rotating component 30.

See also Fig. 3, the axis 20 of the utility model hinge structure 10 comprises an axostylus axostyle 21, and an end of axostylus axostyle 21 is provided with outside thread 211, and the other end is provided with a draw-in groove 212 and a chute 213.

Rotating component 30 is contained in the accepting groove of opening and closing part relative set of above-mentioned mobile phone and can motion vertically in it, and it comprises a rotating cam 31 and a followup cam 32.Rotating cam 31 is cylindrical bodys, it comprises one first central through bore 311 and one first camming surface 312, the internal surface of first central through bore 311 is provided with internal thread 313, the a plurality of projections 314 of the outer installment of rotating cam 31 are used to limit rotating component 30 and rotate in the accepting groove of the opening and closing part of above-mentioned mobile phone.Followup cam 32 also is a cylindrical body, it comprises one second central through bore 321 and one second camming surface 322, second central through bore 321 and the 311 coaxial and perforations of first central through bore, one end of second central through bore 321 is symmetrical arranged two cards and joins groove 323, the second camming surfaces 322 and be used for cooperatively interacting with first camming surface 312 of rotating cam 31.

First elastic component 40 can be a helical spring, its sheathed axis 20 and being contained in two central through

bores

311 and 321 of rotating component 30, and the one end is resisted against the outside thread 211 of axis 20.

Sleeve pipe 50 sheathed axis 20 and can sliding vertically, its front end 51 can slide and replace the other end of first elastic component 40 in second central through bore 321 of followup cam 32, front end 51 comprises that at least one fixture block 511 is used for joining groove 323 with the card of followup cam 32 and cooperates, rear end 52 external diameters of sleeve pipe 50 are greater than the internal diameter of second central through bore 312, and form a boss 522 between itself and the front end 51 and enter in second central through bore 312 with restriction rear end 52.

Second elastic component 60 can be a helical spring, and its a sheathed sleeve pipe 50 and an end are resisted against followup cam 32.

Block 70 is used to replace the other end of second elastic component 60, and it is fixedly arranged in the corresponding accepting groove of offering of fixing part of above-mentioned mobile phone, it comprise one with first through hole 71 and 2 second through holes 72 of two central through bores, 311, the 321 coaxial settings of rotating component 30.

Button 80 comprise one with center hole 81, two fore-sets 82 and a baffle plate 83 of first through hole, the 71 coaxial settings of block 70,2 second through holes, 72 relative set of two fore-sets 82 and block 70, a positioning block 84 (seeing also Fig. 4) is set in the center hole 81, and it cooperates the axial movement with restriction button 80 with the chute 213 of axis 20.The through hole that button 80 can be opened in mobile phone fixing part one sidewall certainly stretches out, and in above-mentioned inside sidewalls cooperation button 80 is limited to mobile phone inside by baffle plate 83.

See also Fig. 4 and Fig. 5, the utility model hinge structure 10 assembly structures are as follows, and axis 20 passes first and second central through bore 311,321, first elastic component 40, sleeve pipe 50, second elastic component 60, first through hole 71 of block 70 and the center hole 81 of button 80 of rotating component 30 successively.Wherein, one snap ring 90 is arranged in the draw-in groove 212 of axis 20 and replaces a surface of block 70, internal thread 313 in first central through bore 311 of the outside thread 211 of axis 20 and the rotating cam 31 of rotating component 30 cooperates, the fore-set 82 of button 80 is contained in second through hole 72 of block 70 and is resisted against the rear end 52 of sleeve pipe 50, at this moment, second elastic component 60 is in contraction state, it is replaced the followup cam 32 of rotating component 30 and produces vertically a power, internal thread 313 because of the rotating cam 31 of rotating component 30 cooperates with the outside thread 211 of the axostylus axostyle 21 of axis 20 again, so trend that rotating component 30 tools move vertically and rotate, but the card that is arranged in followup cam 32 because of the fixture block 511 of sleeve pipe 50 is joined in the groove 323, so sleeve pipe 50 restriction rotating components 30 and it can't be rotated.

During use, if the user needs one-handed operation to open the opening and closing part of mobile phone, only need pressing keys 80, the rear end 52 that the fore-set 82 of button 80 is replaced sleeve pipe 50 is slided it vertically and is compressed first elastic component 40, the fixture block 511 of sleeve pipe 50 front ends 51 will break away from second central through bore, the 321 interior cards of followup cam 32 and join groove 323, the motion of rotating component 30 will no longer be subjected to the restriction of sleeve pipe 50 this moment, thereby in the effect lower edge axial motion of the elasticity release force of second elastic component 60, because of the rotating cam 31 of rotating component 30 is by interior with axis 20, outside thread 313,211 cooperate to realize power screw, so rotating component 30 also will rotate around axis 20 in axial motion, join the fixture block 511 that sleeve pipe 50 was accommodated and engaged to groove 323 once more until the card of followup cam 32, and drive the rotation of above-mentioned opening and closing part thus to realize the unlatching of opening and closing part.

Be appreciated that, when closing above-mentioned opening and closing part by external force, rotating cam 31 is with common rotation in opening and closing part and motion vertically simultaneously, the card that is arranged in followup cam 32 because of the fixture block 511 of sleeve pipe 50 is joined in the groove 323, so sleeve pipe 50 restriction followup cams 32 can't and can only slide it vertically with rotating cam 31 rotations, rotating cam 31 cooperated with second camming surface 322 of followup cam 32 by first camming surface 312 and forced followup cam 32 to slide vertically and compress second elastic component 60 this moment, to produce the trend that continues motion to the second trough structure 3222 of followup cam 32 cross the secondary peak structure 3221 of the second convex surface face 322 when the primary peak structure 3121 of first camming surface 312 after, this moment need not the external force effect, rotating cam 31 will continue rotation and followup cam 32 is incited somebody to action reverse slide vertically, drops down onto the first trough structure 3122 of rotating cam 31 once more until the secondary peak structure 3221 of followup cam 32.Therefore when the user closed above-mentioned opening and closing part, after only need rotated to an angle the opening and closing part by external force, the opening and closing part promptly rotated to closed state automatically.

Be appreciated that two

elastic components

40,60 of the present utility model can substitute with other elastomer such as elastic sponge etc.In addition, the rotating cam 31 of rotating component 30 of the present utility model and followup cam 32 are also plastic in one, that is rotating component 30 only is a rotating casing, it comprises a central through bore, comprise in the central through bore internal thread and one the card join groove, this rotating component 30 also cooperates with above-mentioned axis 20, two

elastic components

40 and 60, sleeve pipe 50, block 70 and button 80 can realize automatic open function.
