Description

Technical Field

[0001] The present invention relates to the field of spinning, and in particular to a driving structure for a spinning. Background Art

[0002] Spinning, also known as spinning, was first invented by American personal trainer and extreme athlete Johnny G in the 1980s. It is a unique and energetic indoor cycling training course that combines music, visual effects, and other elements. After overcoming all the shortcomings of outdoor cycling, due to technological improvements, spinning has become an aerobic exercise that can not only be simple to learn but also can provide a full-body workout. However, in the prior art, spinning bikes generate resistance when driven by the flywheel, belt, and magnetic control module. This makes the overall drive mechanism more expensive in assembly and production. Therefore, a drive structure for a spinning bike is proposed. Summary of the Invention

[0003] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0004] A drive structure for a spinning bike includes a housing, a rotor disposed transversely within the housing, and a rotating shaft disposed transversely in the middle of the rotor. The rotating shaft and the rotor rotate coaxially, and both ends of the rotating shaft pass through the housing and are located on both sides of the housing exterior. The rotor is driven to rotate within the housing via the rotating shaft. A one-way bearing is provided at the connection between the rotating shaft and the rotor, and the one-way bearing is mounted on the rotating shaft. The one-way bearing and the rotating shaft rotate in the same direction, and the rotating shaft rotates in the opposite direction within the rotor via the one-way bearing, thereby driving the rotor to rotate within the housing.

[0005] Preferably, the rotating shaft is equipped with a rotor, and the rotor and the rotating shaft are coaxially rotated, and the rotor rotates inside the rotor through the rotating shaft. A grating encoder is provided inside the rotor, and the rotor senses movement on the side of the grating encoder.

[0006] Preferably, a second ball bearing is sleeved on the outside of the one-way bearing, and the second ball bearing is located inside the rotor, and the rotating shaft drives the one-way bearing to rotate inside the second ball bearing.

[0007] Preferably, the connection between the rotating shaft and the rotor is provided with a first ball bearing and a third ball bearing, and the first ball bearing is located on the left side of the rotor, and the third ball bearing is located on the right side of the housing.

[0008] Preferably, oil shields are provided on both sides of the outside of the rotor, and the oil shields are located inside the shell. The rotor and the oil shields rotate in the same direction, and magnetic steel sheets are provided on the outside of the oil shields, and the magnetic steel sheets rotate and move evenly inside the shell through the rotor.

[0009] Preferably, a magnetic steel ring is mounted inside the shell, and the magnetic steel ring is located on the shell wall inside the shell.

[0010] Compared with the prior art, the beneficial effect of the present invention is that when the shell is installed on the spinning bike, the rotor is driven to rotate inside the shell through the rotating shaft, thereby generating resistance when the spinning bike is driven, thereby facilitating exercise for the user and eliminating the need for the flywheel, belt and magnetic control module to coordinate in order to generate resistance.
