[0028] Traditional spinning relies on mechanical friction to adjust resistance, and mechanical friction resistance is adjusted by brake pads and flywheel friction, which is troublesome and cannot be adjusted accurately in multiple stages. Mechanical friction also causes part wear and noise. Furthermore, the traditional handle design is mostly a single horizontal grip bar, which cannot adapt to the holding needs of different riding postures of users, and is easy to cause arm fatigue or posture imbalance.

[0029] The utility model provides a spinning of electricity generation.

[0030] Please refer to Figures 1 to 4 As shown in the utility model embodiment, the spinning of electricity generation includes support assembly 10, handle support 20, flywheel assembly 30, inertia wheel 40, electromagnetic resistance mechanism 50 and control panel 60. Handle support 20 is connected to support assembly 10 and is located at the head position of the spinning. Flywheel assembly 30 is rotatably connected to support assembly 10, inertia wheel 40 is drivingly connected with flywheel assembly 30, and electromagnetic resistance mechanism 50 is drivingly connected with inertia wheel 40. Control panel 60 is installed on support assembly 10, and control panel 60 is used to generate PWM signal to control electromagnetic resistance mechanism 50 to generate resistance. Electromagnetic resistance mechanism 50 is configured as a generator. Handle support 20 includes first holding support 21 and second holding support 22 connected to both sides of arm 2112 of first holding support 21. First holding support 21 includes U-shaped frame 211 and first holding rod 212 connected to both sides of arm 2112 of U-shaped frame 211, and both ends of second holding support 22 are connected to both sides of arm 2112 of U-shaped frame 211, and the middle part of second holding support 22 protrudes forward of the spinning to form an extended holding elbow 221 for the user to hold.

[0031] Specifically, the frame assembly 10 is the load-bearing frame of the whole vehicle, which is welded or bolted by metal pipes to provide mechanical support. The handle bracket 20 is located at the front of the exercise bike, and the handle bracket 20 is connected to the frame assembly 10 for the user to hold. The flywheel assembly 30 is installed at the rear of the frame assembly 10, which is connected with the pedals, and the user drives the flywheel assembly 30 to rotate by stepping on the pedals with his feet. The inertia wheel 40 is installed in front of the frame assembly 10, which is in transmission connection with the flywheel assembly 30 to increase the rotational inertia, so that the user has the experience of riding a bike; the presence of the inertia wheel 40 makes the movement of the exercise bike more realistic and interesting. The inertia wheel 40 and the flywheel assembly 30 can be in transmission connection with the flywheel assembly 30 through the first belt 41. The electromagnetic resistance mechanism 50 is installed on the frame assembly 10, which generates resistance through electromagnetic induction, and the electromagnetic resistance mechanism 50 is configured as a generator to generate electricity, that is, the electromagnetic resistance mechanism 50 and the generator are an integral part in this application. The electromagnetic resistance mechanism 50 has a rotor, and the rotor of the electromagnetic resistance mechanism 50 is in transmission connection with the inertia wheel 40; the two are in transmission connection through the second belt 42. The control panel 60 is installed on the frame assembly 10, and the control panel 60 is built-in PWM signal generation module, which adjusts the load of the generator according to the user's resistance setting, so as to control the electromagnetic resistance mechanism 50 to generate resistance. In this embodiment, when the user steps on the pedals, the flywheel drives the inertia wheel 40 to rotate, and the inertia wheel 40 drives the rotor of the generator (i.e. the electromagnetic resistance mechanism 50) to rotate, and the magnetic field of the permanent magnet on the rotor cuts the stator coil to generate induced current. The induced current generated in the coil produces a counter magnetic field, which hinders the movement of the rotor and forms resistance. The size of the resistance is proportional to the load of the generator, the greater the external circuit load, the greater the output current of the generator, the stronger the counter magnetic field, and the resistance increases. Since the rotor of the generator is in transmission connection with the inertia wheel 40, and the inertia wheel 40 is in transmission connection with the flywheel assembly 30, the resistance of the user when stepping on the pedals will change according to the adjustment of the control panel 60. The resistance adjustment in this application is controlled by PWM signal, which has high adjustment precision and can realize stepless continuous resistance adjustment; and there is no mechanical friction component, which can reduce wear and noise.

[0032] The handle support 20 comprises a first holding support 21 and a second holding support 22, and the second holding support 22 is connected to the first holding support 21. The first holding support 21 comprises a U-shaped frame 211 and two first holding rods 212, and one first holding rod 212 is connected to each side arm 2112 of the U-shaped frame 211. The second holding support 22 is located between the two side arms 2112 of the U-shaped frame 211, and the two ends of the second holding support 22 are connected to the two side arms 2112 of the U-shaped frame 211 respectively. The middle part of the second holding support 22 protrudes forward of the exercise bike to form an extended holding elbow 221 for the user to hold. The U-shaped frame 211 comprises a bottom arm 2111 and two side arms 2112, and the two ends of the two side arms 2112 are connected to the two ends of the bottom arm 2111 respectively, and the bottom arm 2111 can be held by the user during use; and the first holding rod 212 on each side arm 2112 can also be held by the user. The extended holding elbow 221 of the middle part of the second holding support 22 can also be held by the user. In the embodiment, the handle support 20 has multiple parts that can be held by the user, and the user can change different holding parts to reduce the fatigue caused by holding one position for a long time, thereby improving the enthusiasm of the user for exercise, and further improving the effect of fitness. In addition, the multi-part holding can also adapt to different riding postures (such as sitting posture, standing posture sprint), and the user can select the holding part according to the actual needs. The second holding rod added on the first holding rod 212 can also increase the mechanical structural strength of the handle support 20 as a whole, and avoid the shaking of the handle support 20, thereby affecting the riding experience of the user.
