Fig. 2, Fig. 3 and Fig. 4 are please referred to, the first drive block 33 forms one first convex block adjacent to the one side of the second torsion spring seat 12
331, an actuator 332 is fixed on the first convex block 331 in the surface of the second torsion spring seat 12, the present embodiment, and actuator 332 is adopted
With soket head cap screw, the structure of actuator 332 with no restrictions, can be as needed using any existing knot in other embodiments
Structure.
Fig. 2~Fig. 5 is please referred to, driving mechanism 4 includes the first convex block 331 and one second drive block 41, the second drive block 41
It is arranged and is fixed in drive shaft 2 and between the first drive block 33 and the second torsion spring seat 12, in the present embodiment, the second drive block
41 are keyed with drive shaft 2；Second drive block, 41 periphery is radially formed one second convex block 411, and the first convex block 331 drives second
The circumferential of motion block 41 limits the second convex block 411.
First convex block 331 and the second convex block 411 are cyclic annular in fan along the radial section of drive shaft 2, and the second convex block 411 is most
For minor radius less than the least radius of the first convex block 331, the maximum radius of the second convex block 411 is greater than the most smaller part of the first convex block 331
Diameter.In the present embodiment, the central angle of the first convex block 331 is 130 °, and the central angle of the second convex block 411 is 34 °, in other embodiments
In, the central angle of the first convex block 331 and the second convex block 411 can be arranged according to actual needs, with no restrictions.
In the present embodiment, the two sides adjacent with the second convex block 411 of the first convex block 331 and the second convex block 411 with
The adjacent two sides of one convex block 331 are respectively arranged with a cushion 42.It in other embodiments, can also be only in the first convex block 331
Or second cushion 42 is arranged on convex block 411.

Fig. 2, Fig. 3, Fig. 6 and Fig. 7 are please referred to, the second torsion spring seat 12 forms at least driver slot cooperated with actuator 332
121, actuator 332 is inserted in driver slot 121, and in the present embodiment, driver slot 121 is square.Actuator 332 and driver slot
121 cooperation realizes the synchronous rotation of the first drive block 33 and the second torsion spring seat 12.
Fig. 2~Fig. 5, Fig. 8 and Fig. 9 are please referred to, when spring reset module 92 is installed on door-hinge 9, drive shaft 2 and vertical hinged door
Driving device 91 is sequentially 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, can be arranged the circumferential angle of the second drive block 41 on driving shaft 2 according to actual needs, and
So that the two sides adjacent with the first convex block 331 of second convex block 411 can be with the first convex block 331 after the rotation of the second drive block 41
Two sides face contact, thus drive 33 rotating Vortex of the first drive block.When the first drive block 33 is driven to rotate, the first driving
Block 33 drives 12 rotating Vortex of the second torsion spring seat, and since the first torsion spring seat 11 is fixed on shell 31, so that torsional spring 1 is turned round
Tightly.Drive shaft 2 is persistently rotated, until reaching a predetermined angular, such as when 180 degree, electromagnetic brake 32 is powered, rotor 322 and fixed
Son 321 is fixed to each other, so that the first convex block 331, the second torsion spring seat 12 and the first torsion spring seat 11 are circumferentially fixed, so that
Torsional spring 1 is fixed on the energy storage state with elastic potential energy, meanwhile, the second drive block 41 at this time can with opposite direction free movement,
Motion range, that is, predetermined angle range can adjust the first convex block 331 according to actual needs and the central angle of the second convex block 411 obtains,
For example, predetermined angle range can be set to 0~180 degree.So, the second drive block 41 namely drive shaft 2 can be in 0~180 degrees
It is freely rotated in range.At this point, since torsional spring 1 is fixed, 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, thus release first
Drive block 33, and the second torsion spring seat 12 being attached thereto also loses force constraint, at this point, under the action of 1 elastic force of torsional spring, driving
Second torsion spring seat 12 and the first drive block 33 are rotated to elastic force direction.Then the first convex block 331 and second of the first drive block 33
One face contact of convex block 411 drives the second drive block 41 and drive shaft 2 to rotate together, until being restored to movement starting point, transports
Dynamic starting point can also be limited by external mechanical structure to limit.
In this process, it realizes, in the energized state, torsional spring 1 does not influence the rotation of drive shaft 2, and then nor affects on
The rotation of door-hinge 9, and under off-position, torsional spring 1, which still has, can drive drive shaft 2 to complete the function of resetting.
Referring to Fig. 2, a kind of spring reset module 92 of the embodiment of the present invention two, the structure base of structure and embodiment one
This is identical, and difference is, further includes a pre-load mechanism 5, and pre-load mechanism 5 is used to adjust a rotation angle of drive shaft 2
And to the circumferential locking of drive shaft 2 or unlock.
In the present embodiment, pre-load mechanism 5 includes that a pedestal 51 and a spacer pin 52, pedestal 51 are rotationally sheathed on drive
The first end of moving axis 2, and pedestal 51 and drive shaft 2 form mutual corresponding pin hole 53, in the outer diameter and pin hole 53 of spacer pin 52
Diameter cooperation.Pedestal 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 is in a pre-installation, it can be by pin
Spacer pin 52 is inserted into hole 53, so that drive shaft 2 and 51 synchronous rotary of pedestal, rotating base 51 to required angle, after 180 degree,
Pedestal 5 is fixed on the first torsion spring seat 11 with screw, at this point, torsional spring 1 is pre-loaded to 180 degree, and spring reset module 92
Structure be it is 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, torsional spring 1 can rotate door-hinge, until touching in external mechanical limit structure.
The torsion pre-loaded function for thereby realizing spring reset module 92, the load for carrying out torsional spring 1 without scene are debugged,
Time and the difficulty of installation and debugging is greatly saved.So that spring reset module 92 becomes individual module, departing from original
The role of door machine structure attachment realizes power-off restoration so that spring reset module 92 can be used alone, and can be used for other devices
Function.
