Embodiment
Below in conjunction with specific embodiment, a kind of energy storage output mechanism for spring operating mechanism of the present utility model is specifically described:
As shown in Figure 2, the energy storage output mechanism for spring operating mechanism of the present embodiment, comprise support body, be arranged on the rotating shaft 1 of described support body one end, be arranged on the output toggle arm 4 of the described support body other end, described rotating shaft 1 is set with energy storage bias piece 2, described rotating shaft 1 is also provided with the variable-diameter structure 3 with the radius length gradual change of described rotating shaft 1 unitary rotation, also comprise one end to be connected with described variable-diameter structure 3, and arrange around the peripheral side wall 3a of described variable-diameter structure 3, the other end is connected to driving-chain or the rope 5 of described output toggle arm 4, described energy storage bias piece 2 release energy promote described rotating shaft 1 rotate, described rotating shaft 1 is rotated and is driven described variable-diameter structure 3 to rotate around described rotating shaft 1, and in the rotary course of described variable-diameter structure 3, the arm of force that the pivot of described driving-chain or the relatively described variable-diameter structure 3 of rope 5 is formed changes, and the amplitude of arm of force change coordinates with the change in torque amplitude of described energy storage bias piece 2, make the power output curves switch combined floodgate characteristic curve of driving-chain or rope 5, therefore, energy storage output mechanism of the present utility model adopts variable-diameter structure 3 to rotate and pulls driving-chain or rope 5, by changing relative to the arm of force of driving-chain or rope 5 in variable-diameter structure 3 rotation process, when energy storage output mechanism is released energy, can by regulating the change of the arm of force, realize the effective control to power output, it is made to meet the combined floodgate curve of switch, ensure reliable combined floodgate.
Specifically, described variable-diameter structure 3 is eccentric output wheel, or helical form bar shape, and described energy storage bias piece 2 is torsion spring or ring spring or disc spring.But the structure of the described variable-diameter structure 3 of the present embodiment is not limited thereto, as long as meet with in rotating shaft 1 rotary course, the arm of force of its relative driving-chain or rope 5 reduces with the moment of torsion of energy storage bias piece 2 and changes accordingly, makes it meet M=FL; Thus by adjustment moment of torsion M and the corresponding amplitude of variation of arm of force L, make power output F meet the output state of demand.
In a kind of way of realization, as shown in figures 2-6, in the rotary course of described variable-diameter structure 3, the arm of force that the pivot of described driving-chain or the relatively described variable-diameter structure 3 of rope 5 is formed diminishes gradually, and the moment of torsion of its amplitude diminished and described energy storage bias piece 2 amplitude that diminishes keeps quite, stable output power output;
In another kind of way of realization, as shown in Figure 7, in the rotary course of described variable-diameter structure 3, the arm of force that the pivot of described driving-chain or the relatively described variable-diameter structure 3 of rope 5 is formed reduces, the moment of torsion amplitude that diminishes of the amplitude that early stage diminishes and described energy storage bias piece 2 keeps suitable, the moment of torsion that the amplitude that later stage diminishes is greater than described energy storage bias piece 2 diminishes amplitude, export first to stablize and become large power output afterwards, namely described eccentric output wheel is along with the rotation of rotating shaft 1, the minimizing amplitude of its radius of first half term and the change in torque degree of energy storage torsion spring keep suitable, thus the power output of stable output, its radius of the second half reduces fast with the rotation of rotating shaft 1, thus make the reduction amplitude of radius be greater than moment of torsion reduction amplitude, thus it is very fast to make the arm of force reduce, thus the power output increased is exported in the second half.
Further, described rotating shaft 1 is installed with driver part, one end and the described support body of described energy storage bias piece 2 are fixed, and the other end is release end 2a, and described release end 2a is connected with described driver part.

Further, described driving-chain or rope 5 can be roller chain or steel wire rope, as long as can meet rigidity requirement, described energy storage bias piece 2 is fixing to be fixed on described front plate A by the second pin 8 with the one end on described support body.
In addition, described support body comprises front plate A and the rear plate B of opposing parallel setting, described rotating shaft 1 one end is installed on described rear plate B, the other end stretches out through described front plate A, and described energy storage bias piece 2 is installed between described front plate A and described rear plate B, and described variable-diameter structure 3 is installed on the external part of described rotating shaft 1, the setting of described front plate A and described rear plate B, be convenient to the fixing of energy storage output mechanism, and make the structure of product more compact, space layout is more reasonable.
And, the energy storage output mechanism for spring operating mechanism of the present embodiment, in rotation process, line between the tie point that described driving-chain or rope 5 and points of tangency to the described driving-chain or rope 5 of described variable-diameter structure 3 are connected with described output toggle arm 4 is without the pivot of described output toggle arm 4, thus ensure that, when axis of rotation pulls driving-chain or rope, stuck phenomenon can not occur, ensure that reliability of structure.
Under regard to the energy storage output mechanism of the present embodiment making process be introduced:
As shown in Figure 2, mechanism is in separating brake energy storage state, when mechanism starts to close a floodgate, energy storage bias piece 8 starts release, its release end 2a promotes the first pin 7 and turns clockwise, and then promotion connecting lever weldment 6 drives rotating shaft 1 to turn clockwise, then described variable-diameter structure is turned clockwise to be pulled by chain 5 and turns wall 4 and rotate counterclockwise, in making process, the torque of torsion spring reduces gradually along with spring discharges, vertical range simultaneously between chain 5 and rotating shaft 1, namely the distance volume of the arm of force shortens gradually, by torque formula: M=FL, can reason out, the amplitude of variation of the arm of force and the change in torque amplitude of energy-stored spring keep suitable, then power output F keeps stable, certainly, the different structural design of variable-diameter structure can be passed through according to the actual requirements, make it relative to the arm of force of chain 5 according to setting change, the power output realizing different conditions exports, such as early stage is stable, later stage increases.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And thus the apparent change of extending out or variation be still among the protection range that the utility model creates.
