Abstract

Disclosed are an apparatus for replenishing energy in a flywheel battery when a bicycle is going downhill and a method of use. The bicycle is provided with a manual engaging and disengaging device and a motive power assembly (2), wherein the manual engaging and disengaging device controls whether to replenish energy in a flywheel battery (3) according to the state of travel of the bicycle; and the motive power assembly receives the driving force of a bicycle rear wheel (72) and replenishes energy in the flywheel battery. The benefit is that in the case of no power source, the bicycle can be used to replenish kinetic energy in the flywheel battery. Manually controlling the time for replenishment of energy in the flywheel battery lightens the manpower load. Thus, when the bicycle is going downhill, the apparatus couples with the bicycle to provide kinetic energy to the flywheel (31); and when the bicycle is going uphill or travelling along a flat, the apparatus separates from the bicycle to lighten the manpower load. Using the principle of centrifugal force means that after stopping driving, a drive mechanism can automatically separate from the flywheel to prevent unnecessary wastage of energy from the flywheel.

Description

Device for replenishing flywheel battery with energy of bicycle when going downhill and using method thereof

Technical field

The invention relates to the field of flywheel batteries (or flywheel energy storage devices), and in particular to a device for replenishing energy of a flywheel battery.

Background technique

Among many energy storage devices, the flywheel battery breaks through the limitations of chemical batteries and uses physical methods to achieve energy storage. When the flywheel rotates at a certain angular velocity, it has a certain kinetic energy, and the flywheel battery is converted into electric energy by its kinetic energy. Compared with chemical batteries, flywheel batteries are expected to be the most promising energy storage batteries due to their high efficiency, short charging time, small relative size, and clean and pollution-free.

The working principle of the flywheel battery: There is a motor (electric/generator integrated machine) in the flywheel battery. When charging, the motor runs in the form of a motor, and the externally input electric energy is converted into the kinetic energy of the flywheel by the motor, that is, the flywheel battery is charged. When the outside world needs electric energy, the motor rotates in the form of a generator, and the kinetic energy of the flywheel is converted into electric energy by the generator, and is output to an external load, that is, the flywheel battery is "discharged". In order to reduce windage loss, friction and other energy losses, the flywheel battery is placed in a vacuum box and uses magnetic suspension bearings to support the rotating components.

The flywheel battery has the characteristics of large energy storage density and relatively small size. It is especially suitable for carrying in the field without power supply. Especially for the riders who ride bicycles, when camping in the wild, it is very necessary to have a laptop computer and a radio. High-powered lights support the flywheel battery of electricity. However, the flywheel battery can only drive the generator in the vacuum box to drive the flywheel to rotate, so that the flywheel stores kinetic energy, but there is no power supply in the field to charge the flywheel battery.

The inner driving device comprises a magnetic wheel 51, a rotating shaft 52, a centrifugal mechanism 53 and a friction concave wheel 54, the magnetic wheel 51 is coaxial with the driving sleeve 43, and the magnetic wheel 51 is provided with a plurality of second magnets 511 along the circumference; The second magnet 511 is equal in number to the first magnet 431 in the driving sleeve, and is in one-to-one correspondence and coupled by a magnetic field; the magnetic wheel 51 is coupled to the centrifugal mechanism 53 via the rotating shaft 52.

The centrifugal mechanism 53 is a mechanical automatic control device based on the principle of centrifugal motion. The structure is as shown in FIG. 5 and FIG. 6. On the rotating shaft 52, two first pull rods 531 are respectively provided with two flying hammers 532. The first pull rod 531 is swingable about the pin shaft 533 in a vertical plane. When the rotating shaft 52 rotates, the flying hammer 532 generates a centrifugal movement tendency, the first pulling rod 531 is opened at a certain angle, and the sliding sleeve 535 sleeved on the rotating shaft 52 is moved by the second pulling rod 534 to the friction cam 32 for a distance. The friction cam 32 is coupled to the flywheel 31, and the other end of the flywheel 31 is coupled to the generator 34.

Coupling, the driving sleeve 43 drives the magnetic wheel 51, the centrifugal mechanism 53 and the friction concave wheel 54 to rotate together. When the rotation of the centrifugal mechanism 53 reaches a certain speed, the sliding sleeve 535 in the centrifugal mechanism 53 overcomes the compression under the action of the centrifugal force. The spring force of the spring 536 moves toward the friction cam 32, thereby causing the friction cam 54 coupled to the sliding sleeve 535 to engage the friction cam 32, thereby driving the flywheel 31 to rotate to store energy.

Referring to FIG. 7, when the bicycle is traveling on the ground, the speed regulating disc on the bicycle handle is operated to pull the steel cord 13, and the steel cord 13 pulls the bracket 21 against the elastic force of the tension spring 12 to the opposite direction of the rear wheel 72 of the bicycle, and is installed.

When the outside world needs electric energy, the kinetic energy of the flywheel 31 is converted into electric energy by the generator 34 and output to an external load.

Another implementation method: for a good-powered rider, the invention can also use the present invention to apply supplemental energy to the flywheel battery when driving on a flat surface. The method is to adjust the friction wheel 41 to contact with the rear wheel 72 on the ground (see Fig. 8), and then mount the mounting frame 11 It is fixed to the rear frame 71. In this way, the bicycle can replenish the flywheel battery when driving downhill and on the road. On the uphill, the friction wheel 41 is separated from the rear wheel 72 and no longer consumes the rider's physical strength.
