And because the solar energy drives the electric motor car motor 6 to produce the dish effect of stopping after supplying power, so driving motor gear 1 rotates and needs to overcome the resistance, and this resistance must be overcome by the power of quadriceps femoris muscle.
In the above process, in the view of fig. 4, the first main shaft 12 drives the inner ring of the one-way bearing sleeved on the first main shaft 12 to rotate counterclockwise, at this time, the one-way bearing sleeved on the transmission counter gear 4 'is in a free state, the second main shaft 13 drives the second main shaft transmission gear 2' to rotate clockwise, and the counter transmission chain 11 'rotates clockwise to drive the transmission counter gear 4' to rotate clockwise.
As shown in fig. 6 and 7:
the popliteal muscle is then forced to slowly lower the upper cylinder 85 and lower cylinder 86 until back to the original position.
The swing link 84 is driven to be put down, as shown in fig. 6, the second spindle 13 rotates counterclockwise as shown in fig. 6, the second spindle transmission gear 2 'is driven by the second spindle 13 to rotate counterclockwise at the viewing angle of fig. 6, the reverse transmission chain 11' rotates counterclockwise as shown in fig. 6, the transmission reverse gear 4 'is driven to rotate counterclockwise as shown in fig. 6, the transmission reverse gear 4' drives the outer ring of the one-way bearing sleeved with the transmission reverse gear to rotate counterclockwise, so that the one-way bearing is locked, the inner ring of the one-way bearing is driven to rotate counterclockwise, the first spindle 12 is driven to rotate counterclockwise as shown in fig. 6, and the first spindle 12 rotates clockwise as shown in fig. 7.
The first main shaft 12 drives the motor transmission gear 7 to rotate clockwise as shown in fig. 7, and the motor transmission gear 7 drives the motor gear 1 to rotate clockwise as shown in fig. 7 through the motor transmission chain 17, so as to drive the electric vehicle motor 6 to rotate.
And because the solar energy drives the electric motor car motor 6 to produce the dish effect of stopping after supplying power, so drive motor gear 1 rotates and needs to overcome the resistance, and this resistance must be overcome by the power of popliteal rope muscle.
In the process, in a view angle of fig. 6, the first main shaft 12 drives the first main shaft transmission gear 4 to rotate anticlockwise, the chain 11 rotates clockwise to drive the transmission spur gear 2, the first transition gear 3 and the second transition gear 5 to rotate clockwise, the outer ring of the one-way bearing on the second main shaft 13 sleeved with the transmission spur gear 2 rotates clockwise to cause a free state of the one-way bearing, and at the moment, the second main shaft 13 rotates anticlockwise to drive the inner ring of the one-way bearing on the second main shaft 13 to rotate anticlockwise.
Therefore, no matter the leg is forced to hook the foot or put down, the aim of exercising quadriceps femoris and popliteal cord muscle can be achieved by utilizing resistance, and different resistances can be adjusted through the strength of the leg.
