In the related art, in the field of power generation, it is generally necessary to store excess power at a low power peak so as to release the stored power at a high power peak. The current storage mode is usually stored by a battery, but the storage mode is easy to generate dangers such as burning, explosion and the like by using the battery to store electric power.

In order to solve the above problem, referring to fig. 1 to 4, the present embodiment provides an energy storage device, including: the energy storage device comprises a first fixed end plate 10, a second fixed end plate 20, a torque conversion assembly 30 and an elastic assembly 40, wherein the first fixed end plate 10 and the second fixed end plate 20 are oppositely arranged, and an energy storage space is formed between the first fixed end plate 10 and the second fixed end plate 20; the first and second fixed

end plates

10 and 20 are used to fix the elastic assembly 40. The torque conversion assembly is arranged on one side of the second fixed end plate. The first and second fixed

end plates

10 and 20 may be metal plates or plastic plates. The first and second fixed

end plates

10 and 20 may have a circular or square configuration. The cascade assembly 50 is provided outside the first fixed end plate 10.

The elastic component 40 is arranged in the energy storage space and connected with the torque conversion component, and the torque conversion component rotates the elastic component 40 to generate deformation and store energy. The elastic member 40 is fixed at least at one end to the first and second fixed

end plates

10 and 20. Through the rotation of the torque conversion assembly, the elastic assembly 40 generates elastic deformation, and the electric power is converted into elastic potential energy of the elastic assembly 40. When the electric power needs to be released, the elastic component 40 recovers deformation, drives the torque conversion component to rotate, releases elastic potential energy, and converts mechanical energy into electric energy.

In the solution of the present embodiment, an elastic member 40 is disposed between the first fixed end plate 10 and the second fixed end plate 20. The elastic member 40 is connected to the torque conversion member 30. At the low peak of electricity utilization, the torque conversion assembly 30 is driven by the redundant electric power, and the elastic assembly 40 is driven to deform by the rotation of the torque conversion assembly 30. Thereby, the surplus electric power is converted into deformation energy of the elastic member 40. During peak power usage, the resilient assembly 40 releases stored energy through the torque conversion assembly 30. According to the technical scheme, redundant electric power is converted into mechanical energy through the elastic assembly 40, and battery storage is avoided, so that the situations of combustion and explosion cannot occur, and the use is safer.

In one embodiment, for more power storage, the elastic elements 40 are provided in plurality, the elastic elements 40 are radially arranged in the energy storage space, and the elastic elements 40 are linked with each other. More power can be conserved by the plurality of elastomeric members 40. And through the linkage between the elastic assemblies 40, one elastic assembly 40 rotates and deforms to drive other elastic assemblies 40 to also deform, so that the efficiency of converting electric power into elastic potential energy can be improved.

Further, in order to more effectively link the elastic members 40, a plurality of elastic members 40 are connected to the cascade member 50. Through the tandem assembly 50, the plurality of elastic assemblies 40 can be rotated in synchronization.

Specifically, the cascade assembly 50 includes a plurality of cascade mechanisms, each of which connects two adjacent sets of elastic assemblies, and the cascade mechanisms are engaged with each other through gears. For example, the cascade mechanism is a cascade disk 510, each elastic component is connected with the cascade disk 510, and a plurality of cascade disks 510 are arranged in a meshed manner. It can be seen that, when one elastic member rotates, the cascade disk 510 starts to rotate synchronously by the engagement of the cascade disk 510, and when the cascade disk 510 rotates, the plurality of elastic members also start to rotate and store energy at the same time.

In one embodiment, in order to prevent the elastic elements 40 from storing energy effectively, one end of at least one elastic element 40 is fixedly connected to the second fixed end plate 10 or the second fixed end plate 20. One end of one elastic component 40 is fixedly locked, so that the elastic component 40 can effectively accumulate deformation force. By way of example, the elastic assembly 40 is provided with four, respectively a first, a second, a third and a fourth set of springs. The rotating torque of the torque conversion assembly 30 is firstly applied to the first group of springs, when the first group of springs are tightened, the second group of springs are also driven to rotate, but the torque is increased and converted, the torque ratio is larger, the tightening speed of the first group of springs is much higher than that of the second group of springs, but when the first group of springs are tightened to the limit, the length of the springs is limited by the first fixed end plate 10 and the second fixed end plate 20, the springs cannot be deformed continuously, and all the torque is transmitted to the second group of springs. The second set of springs is coupled to the third set of springs through a cascade plate 510, which is slowed down and transferred to the fourth set of springs. A fourth set of springs is locked to the cascade disk 510.

In one embodiment, to ensure that the elastic component functions more effectively, one end of the elastic component is fixedly connected to the cascade mechanism, and the other end is connected to the torque converter.

Referring to fig. 5, in one embodiment, in order to store more power, the elastic element 40 includes a plurality of elastic energy storage elements, and the elastic energy storage elements are connected in a snap-fit manner along the axial direction. For example, the elastic energy storage assembly comprises a first elastic member 410 and a second elastic member 420, and the first elastic member 410 and the second elastic member 420 are axially connected in a snap-fit manner, so that the first elastic member 410 and the second elastic member 420 are arranged in series, and the deformation capacity is increased by the series connection of the two elastic members. And the buckling connection of the first elastic member 410 and the second elastic member 420 ensures that the deformation force of the first elastic member 410 can be transmitted to the second elastic member 420. And ensure that the axes of the first elastic member 410 and the second elastic member 420 coincide. Of course, the number of the elastic members is not limited to two, and may be three or four in series.

Referring to fig. 6 and 7, in one embodiment, the elastic energy storage assembly includes a plurality of elastic energy storage springs, and the plurality of elastic energy storage springs are sequentially sleeved on the sleeving plates at two sides of the elastic energy storage assembly in a radial direction at equal angular intervals.

Further, the deformation coefficients of the plurality of springs are the same. The number of the springs 411 is four, the deformation coefficients of the four steel wires are the same, the springs are arranged at equal intervals in the circumferential direction, and the radial intervals are consistent. In order to keep the deformation coefficients consistent, the area of the steel wire and the diameter of the position are in an equal ratio relation. The steel wire is firmly embedded into the end cover plates at two ends, the energy storage spring 411 only generates axial extension force and radial tangential torsion when being screwed tightly, and the application direction of the torsion is the screwing force of the spring 411 instead of the opposite direction when in energy storage.

Referring to fig. 8, in one embodiment, the energy storage device includes a stress detector 60, the stress detector 60 is disposed inside the second fixed end plate 20, and the stress detector 60 is connected to the torque converter assembly 30.
