[0024] Example 1, see appendix Figure 1-3 A fitness bike with kinetic energy recovery function includes a bike frame 11 mounted on an I-shaped base 41, a Z-shaped swing arm 16, and a horizontal washing device located at the front end of the bike frame 11. Pedals 14 are mounted inside the bike frame via a V-shaped frame, and a crankshaft 15 is connected to the middle of the pedals. One end of the Z-shaped swing arm 16 is hinged to the crankshaft 15, allowing the swing arm 16 to reciprocate through the hinge structure when the crankshaft rotates. The input shaft 23 of the horizontal washing device is connected to an external... The driven gear 18 has a drive gear 17 meshing with it on one side. A protective cover 51 is installed on the outside of the two gears. The size of the drive gear 17 is larger than that of the driven gear 18. The deceleration motion of the drive gear 17 and the driven gear 18 provides sufficient power to the horizontal washing device. An eccentric rod 19 is provided on the axle of the drive gear 17. The other end of the Z-shaped swing rod 16 is hinged to the outer end of the eccentric rod 19. The Z-shaped swing rod 16 drives the drive gear 17 to rotate through the eccentric rod 19.

[0025] The outer drum 20 of the horizontally placed washing machine is fixed to the I-shaped base 41 by the frame. The inner drum 21 is provided inside the outer drum 20. The inner drum is densely covered with mesh and has an inner clothing inlet in the middle of the side wall of the inner drum 21. The water inlet pipe and the drain pipe are provided at the end of the outer drum 20. The outer drum 20 has an outer clothing inlet in the middle that corresponds to the inner clothing inlet on the inner drum 21. After the two are rotated relative to each other, they can be aligned to put clothes in. One end of the inner drum 21 is connected to the frame by the support shaft 22, and the other end is connected to the frame by the input shaft 23. The inner drum 21 rotates between the supports on both sides through the support shaft 22 and the input shaft 23.

[0026] The bicycle frame 11 is equipped with a seat 12 that can be adjusted horizontally and vertically, and a handlebar 13 that can be adjusted vertically. Users of different heights and weights can adjust the position of the handlebar and seat according to their needs.

[0027] A reinforcing plate is welded and fixed at the bend of the Z-shaped swing arm 16 to improve the overall strength of the Z-shaped swing arm.

[0028] When the exercise bike in this embodiment is in use, the crankshaft 15 rotates by pedaling the pedals 14. The crankshaft 15 causes one end of the Z-shaped swing arm 16 to swing back and forth. The other end of the Z-shaped swing arm drives the eccentric rod 19 to rotate. The eccentric rod drives the drive gear 17 to rotate synchronously. The drive gear drives the driven gear 18 to rotate. The driven gear 18 transmits power to the inner drum 21 of the horizontal washing device through the input shaft 23, realizing the rotation operation of the horizontal washing device. This exercise bike utilizes the kinetic energy generated by cycling while also increasing the fun of cycling exercise, which helps to improve the user's enthusiasm for cycling exercise and improve training effect.

[0029] Example 1, see appendix Figure 4-8This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that a wheel speed adjustment mechanism is provided between the eccentric rod 19 and the Z-shaped swing rod 16. This wheel speed adjustment mechanism includes a T-shaped groove 31 provided inside the eccentric rod 19 and a slider 32 vertically hinged to the end of the Z-shaped swing rod 16. The slider is slidably connected in the T-shaped groove 31. The slider 32 can adjust the position of the Z-shaped swing rod 16 by sliding in the T-shaped groove 31, so that the hinge point of the Z-shaped swing rod 16 can be adjusted along the radial direction of the drive gear 17. A positioning mechanism is provided between the T-shaped groove 31 and the slider 32. The positioning mechanism includes square notches 33 evenly provided on both sides of the T-shaped groove 31, a through hole provided in the middle of the slider 32, and a number of positioning holes 34 evenly provided on the side of the eccentric rod 19. The position hole corresponds to the square notch 33. Two hollow shafts 35 are symmetrically sleeved in the through hole, and a spring 37 is inserted between the two hollow shafts. The spring 37 provides an outward elastic thrust to the hollow shafts 35. The outer end of the hollow shaft 35 is coaxially provided with a pin 36 that is inserted into the positioning hole 34. The elastic force generated by the spring 37 can drive the pin 36 to be inserted into the positioning holes 34 on both sides, locking the slider 32. The pin 36 can also compress the spring 37 and slide inward, thereby disengaging from the positioning hole 34 and unlocking the slider 32 so that it can slide in the T-shaped slide groove 31. At the connection between the pin 36 and the hollow shaft 35, there is a lever 38 that is inserted into the square notch 33. The lever drives the hollow shaft 35 to slide in the through hole, realizing the locking and unlocking of the pin 36. It has the advantages of simple and convenient operation.

[0030] When using the adjustment mechanism of this embodiment, the lever 38 is manually turned to drive the hollow shaft 35 to slide axially within the through hole inside the slider 32. The spring 37 between the hollow shafts 35 is compressed, and the pin 36 moves away from the positioning hole 34 on the eccentric rod 19, releasing its lock on the slider 32. At this time, the Z-shaped swing arm 16 can be held and the slider 32 can be slid within the T-shaped groove 31, so that the end of the Z-shaped swing arm 16 is adjusted radially along the drive gear 17. After the position is adjusted, the two levers 38 are released, and the elastic force of the spring 37 inside the slider 32 drives the two hollow shafts 35 to slide outward. The pin 36 is reinserted into the positioning hole 34, locking the slider 32. This completes the adjustment of the radial position of the Z-shaped swing arm 16 along the drive gear 17, thereby changing the magnitude of the resistance of the Z-shaped swing arm 16 driving the drive gear. The intensity of the cycling exercise can be easily adjusted according to the needs.
