[0026] Reference Figure 1-7 A physical exercise device includes a turntable 1, which is in the shape of a disc as a whole. A plurality of densely arranged anti-skid protrusions 101 are fixedly provided on the upper end surface of the turntable 1. A circular groove 104 is provided at the center of the circle of the upper end surface of the turntable 1.

[0027] In this embodiment, the lower end of the turntable 1 is connected to the base frame 2, and the upper end of the box cover 201 is fixedly installed with a cylinder 202.

[0028] It should be added that the upper end surface of the connecting disk 205 is coaxially arranged on the lower end of the turntable 1, and the turntable 1 and the connecting disk 205 are in contact with each other, and then a number of screws 103 are respectively passed downward through a number of screw holes 105 and tightened in a number of threaded holes 206, so as to fix the turntable 1 and the connecting disk 205 together.

[0029] In this embodiment, a box cover 201 is fixedly installed at the center of the base frame 2, and the inner cavity of the box cover 201 is set downward. The lower end of the box cover 201 is fixedly connected to a manual generator 3. The generator main shaft 402 in the manual generator 3 is vertically upward and hidden in the inner cavity of the box cover 201. A two-way input one-way transmission gear assembly 4 is installed between the generator main shaft 402 and the round block 204. The two-way input one-way transmission gear assembly 4 is hidden in the inner cavity of the box cover 201.

[0030] In this embodiment, the bidirectional input unidirectional transmission gear assembly 4 includes an input shaft 401, a same-direction transmission mechanism 403 and a reverse transmission mechanism 404. The same-direction transmission mechanism 403 is arranged above the reverse transmission mechanism 404. Figure 3 The dotted rectangular frame in the upper middle part is the same direction transmission mechanism 403, and the solid rectangular frame below the dotted rectangular frame is the reverse transmission mechanism 404. The upper end of the input shaft 401 passes through the box cover 201 upwards and is fixedly coaxially installed on the lower end of the round block 204. The input shaft 401 and the generator main shaft 402 are parallel to each other.

[0031] The co-directional transmission mechanism 403 comprises a pinion 40301 and a large gear ring 1 40302 which are meshed with each other, the pinion 40301 is coaxially fixedly mounted on the input shaft 401, a one-way bearing 1 40303 is fixedly mounted in the inner ring of the large gear ring 1 40302, and the inner ring of the one-way bearing 1 40303 is coaxially fixedly mounted on the periphery of the generator main shaft 402;

[0032] The reverse transmission mechanism 404 includes a rotating shaft 40401, a one-way bearing 40402, a small gear 40403, a large gear ring 40404, a large gear 40405 and a small gear 40406. The rotating shaft 40401 and the generator main shaft 402 are parallel to each other. The lower end of the rotating shaft 40401 is rotatably mounted on the upper end of the manual generator 3. The small gear 40403 is coaxially fixedly mounted on the input shaft 401. The outer ring of the large gear 40405 and the outer ring of the small gear 40403 are meshed. The big gear 40405 is coaxially fixedly installed on the rotating shaft 40401, the one-way bearing 2 40402 is arranged directly above the big gear 40405, the inner ring of the one-way bearing 2 40402 is fixedly connected to the rotating shaft 40401, the outer ring of the one-way bearing 2 40402 is fixedly installed in the inner ring of the big gear ring 2 40404, the big gear ring 2 40404 and the outer ring of the small gear 3 40406 are meshed and connected, and the small gear 3 40406 is coaxially fixedly installed on the generator main shaft 402.

[0033] It should be added that the outer rings of the one-way bearing 40303 and the one-way bearing 40402 can only rotate clockwise along the inner ring, that is, the inner rings of the one-way bearing 40303 and the one-way bearing 40402 can only rotate counterclockwise along the outer ring. As is known to all, the manual generator 3 can only rotate in one direction to generate electricity. In this application, the manual generator 3 generates electricity when the generator main shaft 402 rotates counterclockwise.

[0034] The utility model adopts a method of connecting a manual generator 3 below the turntable 1 in the waist twister, and converting the kinetic energy generated by the rotation of the turntable 1 into electrical energy by using the manual generator 3. The manual generator 3 is connected to a storage battery through a guide. The storage battery is mainly used to store the electrical energy generated by the manual generator 3. The storage battery can be pre-buried below the installation position of the waist twister, or fixedly installed on a bracket in the waist twister. In short, the application converts the kinetic energy generated by the exerciser using the turntable 1 into electrical energy through the manual generator 3, and stores the generated electrical energy with the help of the storage battery, thereby improving the utilization rate of the kinetic energy generated by the rotation of the turntable 1. The stored electrical energy can be used to supply power to surrounding public facilities.

[0035] When the turntable 1 rotates clockwise and counterclockwise, the power generation process of the manual generator 3 is as follows:

[0036] refer to Figure 71) When the turntable 1 rotates clockwise, the turntable 1 first drives the input shaft 401 to rotate clockwise through the coaxial transmission of the connecting disk 205 and the round block 204 in the same direction transmission mechanism 403, and then drives the one-way bearing 1 40303 and the generator main shaft 402 to rotate counterclockwise through the reverse transmission of the small gear 40301 and the large gear ring 1 40302 to generate electricity. At this time, the one-way transmission of the one-way bearing 2 40402 in the reverse transmission mechanism 404 can only be an invalid transmission and cannot affect the counterclockwise rotation of the generator main shaft 402;

[0037] refer to Figure 6 2) When the turntable 1 rotates counterclockwise, the turntable 1 first drives the rotating shaft 40401 and the inner ring of the one-way bearing 2 40402 to rotate clockwise through the reverse transmission of the small gear 2 40403 and the large gear 40405 in the reverse transmission mechanism 404, and the outer ring of the one-way bearing 2 40402 is driven to rotate clockwise by the inner ring of the one-way bearing 2 40402, and then drives the generator main shaft 402 to rotate counterclockwise through the reverse transmission of the large gear ring 2 40404 and the small gear 3 40406 to generate electricity. At this time, the one-way transmission of the one-way bearing 1 40303 in the same-direction transmission mechanism 403 can only be an invalid transmission, and can also not affect the counterclockwise rotation of the generator main shaft 402;

[0038] In summary, no matter the turntable 1 in the waist twister rotates clockwise or counterclockwise, it can drive the manual generator 3 to generate electricity, that is, through the two-way input one-way transmission gear assembly 4, the power generation efficiency of the manual generator 3 is greatly improved. Similarly, the manual generator 3 and the two-way input one-way transmission gear assembly 4 can also be installed on the main shaft of the Tai Chi push plate of the fitness equipment to generate electricity.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
