[0034] Working principle and process of the present invention:

[0035] The opening and closing control of the first electromagnetic clutch 16, the second electromagnetic clutch 18 and the hollow shaft motor 1 in the present invention can be controlled by an external control system, mainly based on the opening and closing control; when the energy storage box needs to store energy, there are mainly two energy storage control methods; one is that the first hollow output shaft 3 is fixed and the second hollow output shaft 4 is rotated to realize energy storage in the energy storage box, and the other is that the first hollow output shaft 3 is rotated and the second hollow output shaft 4 is fixed to realize energy storage in the energy storage box.

[0036] The working principle of the first energy storage method is: control the second electromagnetic clutch 18 to be energized, the yoke component on the second electromagnetic clutch 18 can magnetically absorb the flange component and fix it, at this time the first hollow output shaft 3 can be fixed relative to the hollow shaft motor 1; then control the hollow shaft motor 1 to start, so that the motor output shaft 2 rotates, the motor output shaft 2 drives the first sun gear 9 to rotate, under the condition that the first ring gear 8 is fixed, the first sun gear 9 drives the first planetary gear 11 to rotate and rotate around the axis of the first hollow output shaft 3 at the same time, the first planetary gear 11 drives the first planetary carrier 10 to realize synchronous rotation around the axis of the first hollow output shaft 3, and for the reduction output, the first planetary carrier 10 drives the second planetary gear 13 to rotate synchronously, and the first hollow When the output shaft 3 is fixed, the second sun gear 12 is fixed, and the second planetary gear 13 can drive the second ring gear 14 to rotate. At this time, it is an increasing speed rotation. The second ring gear 14 can drive the second hollow output shaft 4 to rotate under the connection of the transmission plate 15. The second hollow output shaft 4 drives the volute spring 7 to curl using the box body 5; after the motor output shaft 2 starts at a fixed speed for a certain time or rotates a certain number of times, the first electromagnetic clutch 16 is controlled to be energized and the hollow shaft motor 1 is controlled to stop starting. At this time, the first electromagnetic clutch 16 can fix the second hollow output shaft 4 relative to the hollow shaft motor 1. At this time, the first hollow output shaft 3 and the second hollow output shaft 4 are relatively fixed, and the volute spring 7 is in a curled state, that is, the curling energy storage of the volute spring 7 is realized.

[0037] The working principle of the second energy storage method is: control the first electromagnetic clutch 16 to be energized, the yoke component on the first electromagnetic clutch 16 can magnetically absorb the flange component and fix it, at this time the second hollow output shaft 4 can be fixed relative to the hollow shaft motor 1; then control the hollow shaft motor 1 to start, so that the motor output shaft 2 rotates, at this time the rotation direction of the motor output shaft 2 should be opposite to the direction of the motor output shaft 2 in the first energy storage method, the motor output shaft 2 drives the first sun gear 9 to rotate, under the condition that the first ring gear 10 is fixed, the first sun gear 11 drives the first planetary gear 11 to rotate and rotate around the axis of the first hollow output shaft 3 at the same time, the first planetary gear 11 drives the first planetary carrier 10 to realize synchronous rotation around the axis of the first hollow output shaft 3, and for the reduction output, the first planetary carrier 10 drives the second planetary gear 13 to rotate, due to The second hollow output shaft 4 is relatively fixed. Therefore, the second ring gear 14 is relatively fixed through the connection with the transmission plate 15, and the second planetary gear 13 can drive the second sun gear 12 to rotate. At this time, it is an increased speed output. The second sun gear 12 can drive the first hollow output shaft 3 to rotate. The first hollow output shaft 3 can drive the volute spring 7 to curl and store energy by utilizing the relatively fixed characteristic of the box body 5 on the second hollow output shaft 4; after the motor output shaft 2 starts at a fixed speed for a certain time or rotates a certain number of times, the second electromagnetic clutch 23 is controlled to be energized and the hollow shaft motor 1 is controlled to stop starting. At this time, the second electromagnetic clutch 21 can fix the first hollow output shaft 3 relative to the hollow shaft motor 1. At this time, the first hollow output shaft 3 and the second hollow output shaft 4 are relatively fixed, and the volute spring 7 is in a curled state, that is, the curling energy storage of the volute spring 7 is realized.

[0038] After the energy storage operation is completed, if the first hollow output shaft 3 needs to output, the second electromagnetic clutch 18 can be controlled to lose power. After the second electromagnetic clutch 18 loses power, the first hollow output shaft 3 rotates under the elastic potential energy of the volute spring 7. At this time, the rotation of the first hollow output shaft 3 is not controlled by the hollow shaft motor 1, but is only driven by the volute spring 7, that is, the elastic potential energy of the volute spring 7 is used to achieve an instantaneous burst and attenuated output form, and the first hollow output shaft 3 has two output ends; when the first hollow output shaft 3 rotates and outputs, the first hollow output shaft 3 will drive the first planetary carrier 10 to rotate through the second sun gear 12, and the first planetary carrier 10 will drive the first sun gear 9 to rotate through the first planetary gear 11, thereby driving the motor output shaft 2 to rotate. Since the motor output shaft 2 rotates without load, although a certain loss is generated to the elastic potential energy of the volute spring 7, the loss value is relatively constant and does not affect the normal output of the first hollow output shaft 3. If it is necessary to further reduce the loss of potential energy of the spiral spring 7 caused by the no-load rotation of the motor output shaft 2, the hollow shaft motor 1 can also be subjected to frequency conversion control in the same rotation direction, so that the speed control of the motor output shaft 2 by the hollow shaft motor 1 matches the speed of the motor output shaft 2 when it rotates without load. This can compensate for the loss of elastic potential of the spiral spring 7 when the motor output shaft 2 rotates without load, thereby reducing the loss of elastic potential energy of the spiral spring 7 on the output shaft 3.

In the present invention, if only the first energy storage method mentioned above is adopted, the unidirectional output of the push-pull rod 28 can be realized. If the first energy storage method and the second energy storage method are alternately used to store energy or only the second energy storage method is used to store energy, the reciprocating linear output of the push-pull rod 28 can be realized; the additional third hollow output shaft 29 can add an output end, which can increase the functional role of the energy storage motor.
