Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of body -building equipment, especially with a kind of body-building bicycle motor assembly of self-power generation that can increase power generation. BACKGROUND

[0002] With people pay more and more attention to fitness, intelligent exercise bicycle is used more and more in life because of its simplicity and convenience. The motor, electronic watch, shuttle display system and the like are integrated on the intelligent exercise bicycle, and it needs electricity, so the exercise bicycle self-power generation device is also increasingly installed on the exercise bicycle. The existing exercise bicycle self-power generation device structure as shown in Figure 1 Figure 2 The small pulley A of generator is pressed against the inner side of exercise bicycle belt B, the pulley drives the small pulley to rotate and then generates electricity to supply motor, electronic watch, shuttle display system. The disadvantage of this structure is that the small pulley on the motor shaft is pressed on the hook groove of the belt. Since the pulley set will have yaw when moving, the small pulley on the motor shaft and the hook groove on the belt cannot completely match, causing the belt to be easily worn, and thus the machine function fails. As shown in Figure 3 Figure 4 Another self-power generation structure is that the small pulley C of generator is pressed against the outer side of exercise bicycle belt D, and the small pulley on the motor is improved to be smooth. The disadvantage of this structure is that the power generation is insufficient when the speed is too low during movement, affecting use, and the assembly is relatively complicated.
