The damp hinge mechanism of the present embodiment realizes automatically springing open by torsion spring 12, torsion spring 12 discharges elastic potential energy live axle 11 and rotates relative to housing 13, and damping grease has suitable viscosity, when axle 11 rotates relative to housing 13, can shear action be there is with these damping slots 111 and produce damping force in the damping grease in damping slot 111, the elastic potential energy release of torsion spring 12 can be slowed down, torsion is made to become soft smooth, and within the specific limits, the damping force that the faster damping grease of the speed that flicks produces is larger, make that the movement velocity of axle 11 is slack-off to slow down, to control to flick speed, and damping grease itself also can play certain sealing and from profit effect, make relative motion more smooth and easy.
When load is larger, need larger torsion to realize automatically springing open function, the resistance that damping grease produces limits by space and self performance, can not provide larger resistance.In order to flick when load is larger and effectively slow down, this damp hinge mechanism also coordinates and have employed friction plate 16 and slow down further, and friction plate 16 is preferably metal friction sheet, friction plate 16 to be fixed on axle 11 and with housing 13 fit against.Particularly, friction plate 16 and the outer side surface of the bottom 132 of housing 13 fit against.In the present embodiment, the center of friction plate 16 is provided with the perforation 161 of non-circular (such as square), the cross section of axle 11 second end coordinates with perforation 161, and the second end that axle 11 exposes is located in perforation 161, friction plate 16 is fixed on axle 11 and rotates together with axle 11.When automatically springing open under the effect at torsion spring 12, axle 11 rotates relative to housing 13, axle 11 is with movable friction plate 16 to rotate together, because the bottom 132 of friction plate 16 with housing 13 is adjacent to, friction plate 16 when rotating and static bottom 132 produce and rub, produce larger surface friction drag, namely when the speed flicked, friction plate 16 can be utilized first to slow down, the resistance that friction plate 16 provides when not changing pressure is actual is kinetic force of friction, this value is a constant power, the elastic force produced when resistance and the torsion spring 12 of friction plate 16 generation offsets certain value, the effect of damping slot 111 internal damping fat just can embody preferably, torsion spring 12 and friction plate 16 and damping grease with the use of under, speed is flicked to reach best rotation.Wherein, spring sheet 17 provides positive pressure to friction plate 16, when the elasticity of adjustment second stop member 18, can change the kinetic force of friction size produced between friction plate 16 and bottom 132.
In fact, when less load, the torsion of the torsion spring 12 of employing is general less, only uses torsion spring 12 to add damping grease and just can realize slow automatically rebounding open function preferably, but stability of strutting system is usually bad, be only suitable for the equipment not having anything to require to support force; But when comparatively heavy load, the torsion of the torsion spring 12 adopted is general larger, beyond the scope that damping grease can work, increase the scope that friction plate 16 works to enable torsion drop to damping grease exactly, and make hinge have down reliable and stable support force in working order (because frictional force is a kind of power of retardation motion trend, all the time contrary with the direction of movement tendency, the power of flicking is weakened when flicking, stop closed when closed, effectively can assist and improve elastic force, provide good support force to equipment).In addition, if only adopt torsion spring 12 to add friction plate 16, and do not adopt damping slot 111 and damping grease, because friction plate 16 provides constant kinetic force of friction, as long as so the power of torsion spring 12 is greater than frictional force, equipment will be in the state accelerating to open always, and the velocity ratio opened only can be slow with torsion spring 12, but the process that whole opening procedure or accelerate, still can not play one and slowly smoothly preferably open effect.
