Please refer to FIGS. 1 to 6, which are schematic view of configuration, a first schematic view, a second schematic view, a third schematic view, a fourth schematic view and a fifth schematic view of a spinning bike of an embodiment of the present invention, respectively. As shown in figures, the spinning bike includes a bike frame 100, a transmission wheel 200, a flywheel 300 and a resistance braking device 400.
The transmission wheel 200 is disposed on the bike frame 100. The flywheel 300 is made of the metal material and driven by the transmission wheel 200 to rotate. Preferably, the metal material of the flywheel 300 includes aluminum; in another embodiment, the spinning bike 10 may include a transmission belt 800 mounted on the flywheel 300 and the transmission wheel 200, so that the transmission wheel 200 can drive the flywheel 300 to rotate.
Furthermore, in an embodiment, the spinning bike 10 can include a pedal assembly 600 and a crankset 700. The crankset 700 includes an end disposed on the transmission wheel 200, and another end connected to the pedal assembly 600, so that a user can step on the pedal assembly 600 to drive the flywheel 300 to rotate. The pedal assembly 600 can include a foot plate to assist the user to step on the pedal assembly 600 more smoothly without slipping off the pedal assembly 600 easily. In an embodiment, the spinning bike includes the resistance braking device 400, so that the resistance of the spinning bike can be adjusted, to assist the user for training.
The resistance braking device 400 includes a resistance adjustment member 900, a magnet assembly 401, a control member 404, a manual brake assembly 402 and a resistance control assembly 403. The resistance adjustment member 900 is connected to the bike frame 100, and the magnet assembly 401 can be pivotally connected on the resistance adjustment member 900. Thus, the magnet assembly 401 is movable in the resistance adjustment member 900 to change the distance from the magnet assembly 401 to the flywheel 300, so as to produce different resistance forces or stop rotation of the flywheel 300.
Furthermore, a spacing distance can be formed between the magnet assembly 401 and the flywheel 300. In an embodiment, the magnet assembly 401 can include magnetic components (such as magnets) disposed on two opposite sides of the flywheel 300. When the spacing distance between the magnet assembly 401 and the flywheel 300 becomes shorter, the electromagnetic induction area between the magnetic components and the flywheel 300 becomes larger, so that the spacing distance can be adjusted to provide resistance forces with different degrees.
The control member 404 is connected to the magnet assembly 401, for example, the control member 404 can be fastened on the magnet assembly 401. Furthermore, in an embodiment, the control member 404 can be rotatably disposed on the magnet assembly 401, and control the rotation of the control member 404 by using elastic force of an elastic device, such as spring. For example, in an embodiment, after the control member 404 is rotated, the control member 404 can be back to its former position by the elastic force of the elastic device.
The manual brake assembly 402 can be disposed on the handlebar of the bike frame 100, and include a brake handle 4021 and a brake control wire 4022. The brake control wire 4022 includes an end connected to the brake handle 4021, and another end connected to the control member 404. When the brake handle 4021 is pressed, the brake control wire 4022 can move the control member 404 to pull the magnet assembly 401, so as to change the spacing distance. In an embodiment, when the flywheel 300 is rotating, and the brake handle 4021 is pressed, the spacing distance can be shortened to be a braking distance, to form electromagnetic induction between the flywheel 300 and the magnet assembly 401. In this case, the magnet assembly 401 is very close to the flywheel 300, so the magnet assembly 401 and the flywheel 300 can have the maximum electromagnetic induction area therebetween, to produce and apply a braking resistance force on the flywheel 300 to stop the flywheel 300 immediately, thereby achieving the manual braking function.
The resistance control assembly 403 can include a motor 4031, a control interface 4032 and a resistance control wire 4033. The resistance control wire 4033 has an end connected to the motor 4031 and another end connected to the control member 404. The control interface 4032 is electrically connected to the motor 4031, and configured to control the motor 4031 to roll or release the resistance control wire 4033, so as to change the spacing distance. In an embodiment, the spacing distance is in a range of a minimum resistance length to a maximum resistance length. Electromagnetic induction can be formed between the flywheel 300 and the magnet assembly 401 to produce and apply different resistance force, in a range of the resistance force corresponding to the minimum resistance length to the resistance force corresponding to the maximum resistance length, on the flywheel 300. For example, the sixteen-level resistance adjustment or smooth resistance adjustment can be provided.
In an embodiment, when the motor 4031 rolls the resistance control wire 4033, the control member 404 can drive the magnet assembly 401 to move away from the flywheel 300, so as to reduce the resistance force applied on the flywheel 300. When the motor 4031 releases the resistance control wire 4033, the control member 404 drives the magnet assembly 401 to move close to the flywheel 300, to increase the resistance force applied on the flywheel 300, thereby providing multi-level resistance force adjustment.
Furthermore, in an embodiment, in order to prevent the brake control wire 4022 and the resistance control wire 4033 from interfering the control member 404 to make the resistance function or braking function abnormal, the motor 4031 can enter an idle state when the brake handle 4021 is pressed, so that the resistance control wire 4033 does not drive the magnet assembly 401.
According to above-mentioned contents, in the spinning bike of the present invention, the manual brake assembly 402 and the resistance control assembly 403 can be integrated in the resistance braking device 400. Ends of the brake control wire 4022 and the resistance control wire 4033 are connected to the motor 4031 and the manual brake assembly 402, respectively, and the other ends of the brake control wire 4022 and the resistance control wire 4033 both are connected to the magnet assembly 401, so as to control the spacing distance between the magnet assembly 401 and the flywheel 300. In an embodiment, when one of the manual brake assembly 402 or resistance control assembly 403 is operating, the other of the manual brake assembly 402 and the resistance control assembly 403 can enter the idle state, so that the manual brake assembly 402 and the resistance control assembly 403 do not interfere with each other. Thus, the resistance braking device 400 can perform multi-level electric resistance adjustment and the braking function.
In an embodiment, the spinning bike of the present invention can include a display device 500 disposed on the bike frame 100 and configured to display the values of the plurality of resistance forces; in another embodiment, the control interface 4032 can include a touch panel 4034. Preferably, the display device 500 and the touch panel 4034 are integrated with each other, to facilitate the user to view data and operate the spinning bike easily. Furthermore, in an embodiment, the control interface 4032 can include at least one button 4035, so that the user can adjust the resistance, or power on or off the spinning bike.
Furthermore, in another embodiment, the control interface 4032 can automatically control the spacing distance between the magnet assembly 401 and the flywheel 300, so that the spinning bike of the present invention can electrically adjust the resistance to provide the user with different training plans, for example, the training plan that the resistance is gradually increased, or the training plan that the resistance is increased and decreased alternatively, to meet user various requirements including wellness, slimming, mountain climbing training or racing training.
In summary, according to technical solution of the present invention, the resistance control wire 4033 can be rolled or released to adjust resistance force, and the manual brake assembly 402 can also perform manual braking function. The resistance control assembly 403 and the manual brake assembly 402 can be integrated in the resistance braking device 400, and the user can use the control interface 4032 to adjust the resistance force or manually operate the manual brake assembly 402 to brake, thereby meeting safety requirement. As a result, in the spinning bike of the present invention can use the resistance braking device 400 to satisfy multi-level resistance adjustment and the braking function, and production cost can be reduced.
The present invention disclosed herein has been described by means of specific embodiments. However, numerous modifications, variations and enhancements can be made thereto by those skilled in the art without departing from the spirit and scope of the disclosure set forth in the claims.
