Internal heat dissipation mechanism of bicycle flywheel, and control method thereof

Abstract

The invention discloses an internal heat dissipation mechanism of a bicycle flywheel. The internal heat dissipation mechanism comprises a flywheel body, the flywheel is formed by wrapping metal pieceson three sides, the internal of the flywheel is provided with a cavity, a shaft hole is arranged in the center of the flywheel, a hollow connecting shaft is inserted into the shaft hole, the connecting shaft is welded and fixed on the flywheel, an air inlet and an air outlet are formed in the connecting shaft, a fan is mounted on the connecting shaft, the fan is movably connected to the connecting shaft through a bearing, a plurality of electromagnet modules are uniformly distributed on the annular inner wall of the flywheel, the electromagnet modules are connected with a power supply and a control assembly outside the flywheel through cables, the fan consists of a plurality of blades, magnets are fixedly installed at the ends, close to the annular inner wall, in the blades, the magneticfield directions of the sides, facing the annular inner wall, of the magnets on the two connected blades are different, the electromagnet modules can be controlled to be in a non-magnetic state, an inner side N-pole state and an inner side S-pole state through the control assembly, and the different electromagnet modules are controlled by the control assembly to drive the blades to rotate.

Description

technical field [0001] The invention relates to the technical field of spinning bicycles, in particular to an internal cooling mechanism for a bicycle flywheel. Background technique [0002] With the improvement of living standards, fitness has become a way for people to keep healthy in today's society. Spinning bicycles, as the most popular fitness equipment on the market, are more and more popular among young people. [0003] At present, the existing spinning bicycles brake the high-speed rotating flywheel through the upper or side brake pads. When the brake pads are in contact with the flywheel, due to the large friction between the friction surface of the flywheel and the brake pads, So fever. Due to the heat generation, parts such as the surface of the flywheel may be thermally deformed, which affects the service life of the flywheel or brake pads, and the frictionally heated flywheel may inadvertently cause injury to the human body. At present, if the general flywhee...

AI Technical Summary

Problems solved by technology

Due to the heat, the surface of the flywheel and other components may be thermally deformed, which will affect the service life of the flywheel or brake pads, and the frictionally heated flywheel will accidentally cause harm to the human body.

At present, if the general flywheel needs to dissipate heat, it can only be carried out externally. The heat inside the flywheel still cannot be dissipated well. However, due to the limited space, it is often impossible to install a cooling motor when installing a heat dissipation mechanism inside the flywheel.
