When the damping energy consumption device for physical training works normally, the rotating arms 12 are driven to rotate through the force application of feet, so that the transmission shaft 16 is driven to rotate, the transmission shaft 16 drives the rotating shaft 24 to rotate in a reciprocating mode through the transmission of the incomplete gear 173, the toothed ring 172, the transmission rack 171 and the transmission gear 22, the rotating shaft 24 drives the partition plate 25 to rotate along the first direction, the partition plate 25 pushes the follow-up rotating plate 29 to rotate synchronously through pushing the damping liquid to flow, the rotating resistance of the rotating shaft 24 is small in the process, the rotating stroke corresponds to the vertical position of the two rotating arms 12, and the phenomenon that dead point positions cannot be overcome due to overlarge resistance when the two rotating arms 12 rotate to the vertical position is avoided; when the stop plate 292 is contacted with the adjusting protrusion 201, the follow-up rotating plate 29 stops rotating, and the partition plate 25 continues to rotate, so that the damping fluid in the two small chambers flows through the flow limiting channel, and resistance is provided for the rotation of the partition plate 25, namely, resistance is provided for the rotation of the transmission shaft 16. When the partition plate 25 rotates until the push rod 253 just contacts with one rectangular frame 263 and rotates along a second direction opposite to the first direction under the drive of the rotating shaft 24, the follow-up rotating plate 29 is pushed to rotate synchronously by pushing the flow of the damping fluid, when the stop plate 292 of the other large chamber contacts with the adjusting protrusion 201, the follow-up rotating plate 29 stops rotating, and when the partition plate 25 continues to rotate until the other end of the push rod 253 just contacts with one rectangular frame 263 of the other large chamber, the partition plate rotates along the first direction again under the drive of the rotating shaft 24.
If the current damping is insufficient to provide enough resistance for the trainer, the rotating speed of the transmission shaft 16 is increased, when the rotating speed of the transmission shaft 16 is increased to a certain value, the inertia block 151 on the outer circumference of the adjusting ring 15 rotates in a direction away from the adjusting ring 15 under the centrifugal action and impacts the other end of the deflection block 142, so that the deflection block 142 rotates around a hinged position with the frame and pushes the damping shell 20 to rotate through the trip block 23, the stop plate 292 positioned in one large chamber is in contact with the adjusting protrusion 201 in advance, the partition plate 25 rotates until the push rod 253 contacts with the rectangular frame 263 of the large chamber, and then the rectangular frame 263 is continuously pushed, so that the included angle of the two rectangular frames 263 in the two large chambers is reduced, and the two adjusting plates 28 positioned in the same large chamber are driven to mutually approach to reduce the flow limiting channel, and the rotating resistance of the rotating shaft 24 and the partition plate 25 is increased; meanwhile, when the two rectangular frames 263 are mutually closed, the rack frame 27 is driven to extend out of the stop plate 292 through the meshing of the toothed plate 262, the synchronous gear 291 and the rack frame 27, and the mutual approaching displacement of the two rectangular frames 263 is equal to the displacement of the single rack frame 27 extending out of the stop plate 292, so that when the rotating speed of the transmission shaft 16 is reduced, the rack frame 27 is contacted with the adjusting protrusion 201 after the damping shell 20 recovers the initial position under the action of the torsion spring, and the push rod 253 is just contacted with the rectangular frames 263 when the partition plate 25 rotates to the stroke end point, so that when the damping shell 20 rotates due to the increase of the rotating speed of the transmission shaft 16 next time, the push rod 253 at the end part of the partition plate 25 can further push the rectangular frames 263.
