Claims

1. An energy storage assist device, characterized by, include: Base; A first cam is rotatably mounted on the base, and the first cam has a first fixed position; The first traction component has one end fixedly connected to the first fixed position; The first elastic element is fixedly connected to the base, and the other end of the first traction element is fixedly connected to the first elastic element. A first guide wheel is disposed on the base for guiding the first traction member and is located between the first cam and the first elastic member; The energy storage and assist device has an energy storage state and an energy release state; When the first cam is rotated by an external force, the first traction member is wound around the first cam, causing the first elastic member to deform until it reaches a fully stored energy state. At this time, the part of the first traction member from the first cam to the first elastic member is straight and is consistent with the extension and contraction direction of the first elastic member. At this time, the first traction member is not in contact with the first guide wheel. When the energy storage and assist device is in the energy release state, the first elastic element releases elastic potential energy, and the portion of the first cam in the first traction member that extends from the first elastic element deviates from the extension and retraction direction of the first elastic element.

2. The energy storage assist device of claim 1, wherein It also includes a second cam, a second traction member, a second elastic member, and a second guide wheel, which are respectively and symmetrically arranged to correspond one-to-one with the first cam, the first traction member, the first elastic member, and the first guide wheel; The first elastic element and the second elastic element release their elastic potential energy in opposite directions.

3. The energy storage assist device of claim 2, wherein The first cam and the second cam are integrally formed.

4. The energy storage assist device of claim 1, wherein: The first elastic element is a helical spring, and the energy storage and assist device further includes a spring sleeve, which is used to accommodate the first elastic element; The spring sleeve has a pusher at one end away from the first cam, and the first traction member is fixedly connected to the first elastic member through the pusher.

5. The energy storage assist device of claim 4, wherein When the first traction member is subjected to force, it drives the pushing member to move along the extension and retraction direction of the helical spring to compress the helical spring.

6. The energy storage assist device of claim 1, wherein The first cam is provided with a first guide groove, and the first traction member is wound around the first guide groove.

7. The energy storage assis tance device of claim 2, wherein The first traction component and / or the second traction component are selected from one of plate chains, roller chains, wire ropes and lifting chains.

8. A photovoltaic device, characterized by The device includes the energy storage and assist device as described in any one of claims 1 to 7, and further includes a column, a drive shaft, and a photovoltaic panel; The fixed end of the drive shaft is fixedly connected to the column, and the output end is fixedly connected to the photovoltaic panel; The energy storage assist device is connected to the drive shaft and is used to provide auxiliary torque to drive the photovoltaic panel to rotate around the drive shaft.
