Description

[0002] The flywheel is a disc-shaped part with a large moment of inertia, which acts as an energy storage. For a four-stroke engine, work is done once every four piston strokes, that is, only the power stroke does work, while the exhaust, intake and compression strokes all consume work. Therefore, the torque output by the crankshaft changes periodically, and the crankshaft speed is also unstable. In order to improve this situation, a flywheel is installed at the rear end of the crankshaft; The mechanical energy stored in the flywheel braking process is converted and wasted during braking. The existing flywheel energy storage system uses the energy storage system to absorb the energy of the flywheel braking during braking.

[0013] A flywheel energy storage braking energy recovery method comprises the following steps: S1: The driving component transmits the collected mechanical force to the surface of the flywheel through the contact component, and drives the flywheel to rotate, reducing the mechanical force required to start the flywheel again; S2: The flywheel will rotate inside the arc friction frame, and the arc friction frame will be limited by the pressure during rotation, and the mechanical force of the flywheel braking will be recovered by the movement of the arc friction frame; S3: When the elastic sheet moves, it pushes the force-bearing ring to rotate on the surface of the rotating rod, and the mechanical force of the flywheel braking is collected by the rotation of the rotating ring and the force-bearing ring; S4: The telescopic spring rod can push the bent rod to move. When the bent rod moves, it pushes the flywheel to start rotating through the contact parts, converting the recovered mechanical force into the mechanical force required for starting the flywheel.

[0014] The present invention has the following beneficial effects: The present invention provides a recovery component inside the shell. When the flywheel rotates, the recovery component is pushed to rotate inside the shell through friction. After the flywheel completes the braking work, the recovery component stops synchronously with the flywheel through friction. The recovery component uses the pressure when the flywheel rotates to push the transmission component to deform. The transmission component transmits the mechanical force of the flywheel braking to the driving component through deformation. When the flywheel starts to work again, the driving component transmits the collected mechanical force to the surface of the flywheel through the contact component and pushes the flywheel to rotate, thereby reducing the mechanical force required when the flywheel starts again, thereby achieving the purpose of recycling the flywheel braking energy.

[0015] When the flywheel of the present invention rotates inside the shell through the rotating rod, the flywheel will generate friction with the inner wall of the arc friction frame during rotation. The arc friction frame pushes the sliding frame to move through the friction, and the sliding frame pushes the fixed ring to rotate inside the shell through the bracket. When the arc friction frame is driven until the fixed ring reaches a certain position, the flywheel will rotate inside the arc friction frame. At the same time, the arc friction frame is limited by the pressure during rotation, and the movement of the arc friction frame is used to recover the mechanical force of the flywheel during braking.

[0016] The sliding frame of the present invention pushes the fixed rod to move through the central frame when moving. The fixed rod pushes the rotating ring to rotate on the surface of the rotating rod through the connection between the arc plate and the vertical rod when moving. The rotating ring pushes the slider to slide inside the arc slide frame through the vertical rod, thereby improving the stability of the rotating ring when rotating. When the vertical rod moves, it pushes the elastic sheet to move inside the shell through the push rod. When the elastic sheet moves, it pushes the force ring to rotate on the surface of the rotating rod, and the rotation of the rotating ring and the force ring is used to collect the mechanical force during flywheel braking.

[0017] The force ring of the present invention pushes the moving block to slide inside the semicircular slide slot frame by squeezing the spring sheet when rotating. The moving block pushes the arc spring frame to deform through the cylindrical rod when moving, and pushes the telescopic spring rod to squeeze the surface of the base through the arc spring frame. The mechanical force of the flywheel is recovered and stored by the contraction of the telescopic spring rod. When the flywheel needs to be started again, the electric rod pulls the support frame to separate from the surface of the base, so that the telescopic spring rod can push the bent rod to move. When the bent rod moves, it pushes the flywheel to start rotating through the contact component, thereby converting the recovered mechanical force into the mechanical force required for starting the flywheel.

[0018] The flywheel of the present invention pushes the pressure plate to move when it rotates, and the pressure plate pushes the squeeze elastic sheet to deform when it moves, so as to avoid affecting the use of the flywheel. When the pressure plate needs to transmit and use the recovered mechanical force, the pressure plate will push the flywheel to rotate, and the pressure plate will use the squeezing of the contact plate to position it, so that the recovered mechanical force can assist the flywheel to start working through the pressure plate.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the vertical rod 33 moves, it pushes the elastic sheet 40 to move inside the housing 2 through the push rod 34. When the elastic sheet 40 moves, it pushes the force ring 38 to rotate on the surface of the rotating rod 6. The rotation of the rotating ring 30 and the force ring 38 is used to collect the mechanical force of the flywheel 5 during braking. When the force ring 38 rotates, it pushes the moving block 45 to slide inside the semicircular slot frame 44 by squeezing the elastic sheet 43. When the moving block 45 moves, it pushes the circular arc spring frame 46 to produce deformation through the cylindrical rod 50, and pushes the telescopic spring rod 49 to squeeze the surface of the base 55 through the circular arc spring frame 46, so as to utilize the contraction of the telescopic spring rod 49 to exert the mechanical force on the flywheel 5.
