torsion pads

22,23, cam bit 50, a plurality of friction pads 25 and disk gasket 24 in regular turn; And endways with 26 lockings of a nut; Wherein, Above-mentioned two

torsion pads

22,23 have corresponding concaveconvex structure, and with these friction padss 25, disk gasket 24 torsion in when rotation are provided jointly; And cam bit 50 is to wear to be fixed on the axle center 20; And be provided with around the cam bit first against section 51 be connected with one first against section 51 second against section 52; In the case study on implementation of the utility model; First is cambered surfaces against section 51, and second are planes against section 52, and second is provided with a turning point 521 and is divided into leading portion 522 and back segment 523 with second against section 52 against section 52.

In addition; Hinge 10 is provided with a blocking element 60 on second fixed base 40; One side of blocking element 60 is provided with resistance portion 61, and opposite side is provided with joint 62, and wears blocking element 60 and blocking element 60 is fixed on second fixed base 40 with a fixed block 63; And also be provided with a support block 64 between the blocking element 60 and second fixed base 40, support block 64 also is that fixture 63 wears and is fixed on second fixed base 40; And being provided with a containing space 42 on the position of corresponding blocking element 60, second fixed base 40 is used for holding an elastomer 44; Like spring, be used for fixing elastomer 44 but also be provided with a latch 43, an end of elastomer 44 is the joints 62 that link blocking element 60; And under normal conditions; Promote blocking element 60 with the elastic force of elastic component, make the resistance portion 61 of blocking element 60 be resisted against cam bit 50 around, above structure is the main structure of the utility model.

Like Fig. 3-1 to shown in Fig. 3-4; The hinge 10 of the utility model is the electronic equipment that can be applicable to flip; Like notebook computer, mobile phone etc., and with the display device of the first fixed base 30 link electronic equipment drawing-pushing types of hinge 10, with the button of second fixed base, 40 link electronic equipments; When display cover was combined in button portion, first fixed base 30 and second fixed base 40 were closed condition, made the resistance portion 61 of blocking element 60 promoted by elastomer 44, and be resisted against cam bit 50 first on section 51 (shown in Fig. 3-1); When if the application of force is raised first fixed base 30, first fixed base 30 can produce rotating distance by relative second fixed base 40, at this moment; First fixed base, 30 drive axle center 20, and then axle center 20 interlock cam bits 50 are rotated synchronously, make the resistance portion 61 of blocking element 60 break away from first against section 51; And be resisted against second the leading portion 522 against section 52; Thereby a kind of auxiliary force that promotes axle center 20 rotations is provided, and with the minimizing rotary torsion, and resistance is installed in the gravity of the display device (not shown) of first fixed base 30; Because the direction of auxiliary force is identical with the direction that user's application of force is opened, so the user can reach labour-saving effect (shown in Fig. 3-2) when unlatching is initial.

When first fixed base 30 and second fixed base 40 rotate to about 90 when spending relatively, the resistance portion 61 of blocking element 60 is resisted against on the turning point 521, and at this moment, the torsion of rotation recovers normal state (shown in Fig. 3-3); When if first fixed base 30 and the 40 lasting rotations relatively of second fixed base are spent above 90; The resistance portion 61 of blocking element 60 will break away from turning point 521; And be resisted against second the back segment 523 against section 52, the gravity that also provides an auxiliary force to revolt the display device (not shown), this moment auxiliary force direction and user's application of force unlatching in the opposite direction; And then the lifting rotary torsion, increase and continue to raise required strength (shown in Fig. 3-4).Therefore, when unlatching is initial, because the display device on first fixed base 30 leans forward; Utilize auxiliary unlatching of elastic force of elastomer 44, reach the labor-saving effect, be opened to after 90 degree; Because the layback of the display device on first fixed base 30 through the elastic force supplemental support of elastomer 44, avoids display device to turn over.
