Fig. 2~Fig. 5, Fig. 8 and Fig. 9 are referred to, when spring reset module 92 is installed on door-hinge 9, drive shaft 2 and vertical hinged door
Drive device 91 is connected, and the course of work of spring reset module 92 is as follows：
In initial state, drive shaft 2 is driven to rotate by being opened flat door drive 91 or external force, meanwhile, the second drive block
The 41 also drive of driven shaft 2 rotations, the circumferential angle of the second drive block 41 on driving shaft 2 can be set according to being actually needed, and
So that after the rotation of the second drive block 41, the two sides adjacent with the first projection 331 of the second projection 411 can be with the first projection 331
Two sides contact, so as to drive the rotating Vortex of the first drive block 33.When the first drive block 33 is driven to rotate, the first driving
Block 33 drives the rotating Vortex of the second torsion spring seat 12, and because the first torsion spring seat 11 is fixed on housing 31, so that torsion spring 1 is turned round
Tightly.Continue rotation driving axle 2, until reach a predetermined angular, for example during 180 degree, electromagnetic brake 32 is powered, rotor 322 and fixed
Son 321 interfixes, and then make it that the first projection 331, the second torsion spring seat 12 and the first torsion spring seat 11 are circumferentially fixed, so that
Torsion spring 1 is fixed on the stored energy state of flexible potential energy, meanwhile, the second drive block 41 now can with opposite direction free movement,
Range of movement is that predetermined angle scope can obtain according to the central angle for being actually needed the first projection 331 of adjustment and the second projection 411,
For example, predetermined angle scope can be set to 0~180 degree.So, the second drive block 41 namely drive shaft 2 can be in 0~180 degrees
In the range of freely rotate.Now, because torsion spring 1 is fixed, so as to not influence the rotation of drive shaft 2.
When power is off, or artificially cutting off 32 circuit of electromagnetic brake, electromagnetic brake 32 loses brake weight, so as to discharge first
Drive block 33, and the second torsion spring seat 12 being attached thereto also loses force constraint, now, and in the presence of the elastic force of torsion spring 1, driving
Second torsion spring seat 12 and the first drive block 33 rotate to elastic force direction.Then the first projection 331 and second of the first drive block 33
The face contact of projection 411, drives the second drive block 41 and drive shaft 2 to rotate together, until returning to motion starting point, transports
Dynamic starting point can also be limited by outside mechanical structure is spacing.
In this process, realize, in the energized state, torsion spring 1 does not influence drive shaft 2 and rotated, and then nor affects on
The rotation of door-hinge 9, and under off-position, torsion spring 1, which still possesses, can drive drive shaft 2 to complete the function of resetting.
Referring to Fig. 2, a kind of spring reset module 92 of the utility model embodiment two, the knot of its structure and embodiment one
Structure is essentially identical, and its difference is, in addition to a pre-load mechanism 5, and pre-load mechanism 5 is used for the rotation for adjusting drive shaft 2
Angle and to 2 circumferential locking of drive shaft or unblock.
In the present embodiment, pre-load mechanism 5 includes a base 51 and a spacer pin 52, and base 51 is by being rotationally arranged
In the first end of drive shaft 2, and base 51 forms mutual corresponding pin-and-hole 53, the external diameter and pin-and-hole of spacer pin 52 with drive shaft 2
53 minor diameter fits.Base 51 forms corresponding first connecting hole with the second torsion spring seat 12.
Due to the use of pre-load mechanism 5 so that the spring reset module 92 of the present embodiment in a pre-installation, can be by pin
Spacer pin 52 is inserted in hole 53 so that drive shaft 2 and the synchronous rotary of base 51, rotating base 51 to required angle, and after 180 degree,
Base 5 is fixed on the first torsion spring seat 11 with screw, now, torsion spring 1 is pre-loaded to 180 degree, and spring reset module 92
Structure be fixed, can store, transport.When installing spring reset module 92, spring reset module 92 need to only be installed solid
After door-hinge 9, spacer pin 52 is taken out, torsion spring 1 can rotate door-hinge, until touching in outside mechanical limit structure.
The torsion pre-loaded function of spring reset module 92 is so achieved that, the loading that torsion spring 1 is carried out without scene is debugged,
Greatly save time and the difficulty of installation and debugging.So that spring reset module 92 turns into single module, departing from original
The role of door mechanism annex so that spring reset module 92 can be used alone, and can be used for other devices, realize power-off restoration
Function.
