Internal cooling mechanism of bicycle flywheel and control method thereof

Abstract

The invention discloses an internal heat dissipation mechanism of a bicycle flywheel, which comprises a flywheel body, the flywheel is formed by covering metal parts on three sides, and has a cavity inside, and the center of the flywheel has a shaft hole, and an inner hollow connection is inserted in the shaft hole The connecting shaft is welded and fixed on the flywheel, the connecting shaft is provided with an air inlet and an air outlet, a fan is installed on the connecting shaft, and the fan is movably connected to the connecting shaft through a bearing, and a plurality of electromagnets are evenly distributed on the annular inner wall of the flywheel Module, the electromagnet module is connected with the power supply and control assembly outside the flywheel through cables. The fan is composed of multiple blades. The inner end of the blade is fixed with a magnet near the inner wall of the ring. The magnets on the two connected blades face the ring. The direction of the magnetic field on one side of the inner wall is not the same. The electromagnet module can be controlled by the control assembly to be in the non-magnetic state, the inner N-level state, and the inner S-level state. The control assembly controls different electromagnet modules 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.
