Pedaling vibrational apparatus

A pedaling vibrational apparatus, comprising a seat body, a pedal assembly, a gear plate assembly, a drive assembly and an eccentric assembly;

• the seat body including an I-shaped bottom base and a support frame, wherein the pedal assembly, the gear plate assembly, the drive assembly and the eccentric assembly are mounted to the support frame, the support frame being provided with a plurality of shaft holes for mounting the pedal assembly, the gear plate assembly, the drive assembly and the eccentric assembly;
• the pedal assembly being mounted on the seat body, the pedal assembly including a main rod, a secondary rod and two pedals, the main rod being axially connected to the support frame through a first shaft, the first shaft serving as a rotation center, two ends of the main rod being provided with first mounting portions respectively, the main rod being provided with a curved groove, the secondary rod being mounted to a lower end of the main rod under the first shaft, the secondary rod being connected through at least one second shaft passing through the curved groove of the main rod, the at least one second shaft serving as a lower support member when the main rod is swung, two ends of the secondary rod being provided with second mounting portions respectively, the two pedals each having a pedal portion and a connecting portion, the connecting portion having an upper connecting hole and a lower connecting hole, the upper connecting holes of the two pedals being connected with the first mounting portions respectively, the lower connecting holes of the two pedals being connected with the second mounting portions respectively;
• the gear plate assembly including a first gear plate and a second gear plate, the first gear plate being mounted between the support frame and the main rod, the second gear plate being mounted between the secondary rod and the drive assembly, the first gear plate having a first curved surface corresponding to the curved groove, the first curved surface abutting against a lower end of the at least one second shaft, the first gear plate having a lower curved gear rack;
• the second gear plate having a second curved surface, the second curved surface abutting against the lower end of the at least one second shaft, the second gear plate having an upper curved gear rack;
• the drive assembly including a first linking gear, a second linking gear, a first linking shaft, a first transmission gear and a second transmission gear;
• the first linking gear, the second linking gear, the first linking shaft and the first transmission gear being coaxially arranged, the first linking gear being meshed with the lower curved gear rack, the second linking gear being meshed with the upper curved gear rack, the first linking gear and the second linking gear being turned in opposite directions, unidirectional bearings being mounted in the first linking gear and the second linking gear so that the first linking shaft is rotated in a single direction;
• the first transmission gear being mounted on the first linking shaft, the second transmission gear including a small gear and a large gear, the small gear being meshed with the first transmission gear, the large gear driving the eccentric assembly to rotate;
• the eccentric assembly including a gear and an eccentric block, the gear being meshed with the large gear and driven by the large gear to rotate, the eccentric block being mounted on the gear and driven by the gear to rotate.
