The control device comprises a motor driver and a motor, with the motor driver controlling the torque of the motor. The fitness device is connected to the motor; when the fitness device is subjected to tension, the motor driver controls the motor to operate in a power-generating state. The fitness device overcomes the braking torque of the motor, pulling the motor to rotate, thus generating electricity. The energy storage device is electrically connected to the control device and stores the electrical energy generated by the motor. This utility model's strength-based fitness equipment uses the motor driver to control the torque of the motor for weight distribution, making it very convenient to add or remove weight. It utilizes kinetic energy to drive the motor to generate and store electricity.

[0024] Example 1
[0025] Please see Figure 1-5 This utility model provides an embodiment of a fitness equipment using a speed-increasing reversing gearbox, comprising: an outer shell 100, a base 300 disposed below the outer shell 100, and a seat 400 disposed on one side of the upper end of the base 300; further comprising: an inner cavity 1001 installed inside the outer shell 100, a speed-increasing reversing gearbox 102 disposed on the upper side inside the inner cavity 1001, a first rotating disk 107 and a second rotating disk 108 respectively disposed on both sides of the speed-increasing reversing gearbox 102, the first rotating disk 107 and the second rotating disk 108 being rotatably connected to the speed-increasing reversing gearbox 102, thereby increasing the speed... A generator 103 is installed on the exterior of one end of the commutator gearbox 102. An electromagnetic adjustment mechanism 104 is installed on one side of the generator 103. A first connecting end 1031 is installed at one end of the generator 103, and a second connecting end 1041 is installed at one end of the electromagnetic adjustment mechanism 104. Both the first connecting end 1031 and the second connecting end 1041 are rotatably connected to the generator 103 and the electromagnetic adjustment mechanism 104 via a belt 109. Two connecting fixing heads 106 are installed on both sides of the outer wall of the other end of the speed-increasing commutator gearbox 102. The two connecting fixing heads 106 are connected by a fifth... A central rotating shaft 105 is fixedly connected. The fifth central rotating shaft 105 passes through the interior of the speed-increasing reversing gearbox 102. A first gear 10201 is located at the middle position of the outer wall of the fifth central rotating shaft 105. A reserved inner cavity 102011 is provided inside the first gear 10201. A first central rotating shaft 10202 is provided on one side of the exterior of the fifth central rotating shaft 105. A second central rotating shaft 10203 is provided on one side of the first central rotating shaft 10202. A third central rotating shaft 10204 is provided below the second central rotating shaft 10203. A fourth central rotating shaft 10205 is provided on one side. A second gear 102021 and a third gear 102022 are provided on the outer wall of the first central rotating shaft 10202. The first gear 10201 meshes with the second gear 102021 and rotates. A fourth gear 102031, a fifth gear 102032 and a sixth gear 102033 are provided on the outer wall of the second central rotating shaft 10203. A seventh gear 102041 and an eighth gear 102042 are provided on the outer wall of the third central rotating shaft 10204. A ninth gear 102051 is provided on the outer wall of the fourth central rotating shaft 10205.
[0026] Please see Figure 1As a further implementation of this solution, two handle rods 200 are provided on both sides of the outer shell 100, and both handle rods 200 are fixedly installed with two connecting fixing heads 106. A display screen 101 is provided on one side of the outer shell 100.
[0027] When the handle 200 is pushed up and down, the device can drive the connecting fixing head 106 to drive the speed-increasing reversing gearbox 102 to rotate clockwise.
[0028] When the fifth central rotating shaft 105 rotates clockwise: the first gear 10201 fixed to it rotates in the same direction, driving the second gear 102021 meshing with it to rotate counterclockwise; the third gear 102022 on the coaxial first central rotating shaft 10202 rotates in the same direction; the second gear 102021 rotating counterclockwise drives the fourth gear 102031 meshing with it on the second central rotating shaft 10203 to rotate clockwise; simultaneously, the fifth gear 102032 and the sixth gear 102033 on the second central rotating shaft 10203 are both mounted on one-way bearings in the same direction clockwise. Because the one-way bearings do not participate in the transmission of rotation, the first rotating disk 107 coaxial with it drives the electromagnetic adjustment mechanism to rotate via the belt 109, and rotates with the first... After the ninth gear 102051, which meshes with the fifth gear 102032, rotates counterclockwise, the eighth gear 102042, which meshes with it, rotates clockwise, driving the coaxial third central rotating shaft 10204, which is fixed to it, to rotate clockwise. This, in turn, drives the second rotating disk 108 to rotate clockwise. Through the belt 109, the rotation clockwise drives the generator 103 connected to the belt 109 to rotate clockwise. This effectively ensures that, regardless of whether the fifth central rotating shaft 105 rotates clockwise or counterclockwise from its initial position, it ultimately drives the generator 103 to rotate clockwise in an orderly manner, inputting power to supply the display screen 101 for display. At the same time, it also effectively adjusts the electromagnetic resistance of the electromagnetic adjustment mechanism 104 through the transmission command.
[0029] Example 2
[0030] When the handle 200 is pushed up and down, the device can drive the connecting fixing head 106 to drive the speed-increasing reversing gearbox 102 to rotate in two modes: counterclockwise and reverse clockwise.
[0031] When the fifth central rotating shaft 105 rotates counterclockwise: the first gear 10201 fixed to it rotates in the same direction, driving the second gear 102021 meshing with it to rotate clockwise; the third gear 102022 on the coaxial first central rotating shaft 10202 rotates in the same direction; the second gear 102021 rotates counterclockwise, driving the fourth gear 102031 meshing with it on the second central rotating shaft 10203 to rotate counterclockwise; simultaneously, the fifth gear 102032 and the sixth gear 10203 on the second central rotating shaft 10203... All three are mounted with counter-clockwise one-way bearings. Since the one-way bearings do not participate in the transmission of rotation, the first rotating disk 107, which is coaxial with it, drives the electromagnetic adjustment mechanism to rotate via belt 109. When the sixth gear 102033 rotates counterclockwise, the meshing seventh gear 102041 rotates clockwise, which drives the coaxial third central rotating shaft 10204, which is fixed with it, to rotate clockwise. This drives the second rotating disk 108 to rotate clockwise, which in turn drives the generator 103 connected to belt 109 to rotate clockwise.
[0032] This effectively ensures that whether the fifth central rotating shaft 105 rotates clockwise or counterclockwise from its initial position, it will ultimately drive the generator 103 to rotate clockwise in an orderly manner, supplying power to the display screen 101 for display. At the same time, it can also effectively adjust the electromagnetic resistance of the electromagnetic adjustment mechanism 104 by sending commands.
