according to the rule, when the sporter runs on the running belt, the damping plate can periodically move downwards and rebound upwards;
the damping plate is impacted by the pedal to move downwards, the two connecting rods drive the two sliding rings to respectively move to be gradually close to the hollow cylinder body by the downward displacement of the damping plate, the right piston push rod and the left piston push rod respectively drive the right piston disc and the left piston disc to move to be mutually close by the mutual close movement of the two sliding rings, the gas in the damping air chamber is rapidly compressed by the mutual close movement between the right piston disc and the left piston disc, the compressed gas in the damping air chamber cannot instantly enter the elastic pressure accumulation air bag through the first gas guide channel under the action of the flow limiting cylinder, and then the inside of the damping air chamber forms the bounce force to the right piston disc and the left piston disc, so that the damping and restraining tendency that the right piston disc and the left piston disc continuously move to be mutually close to each other is realized, the damping effect on the downward movement of the damping plate is realized, and the gas in the damping air chamber is gradually compressed, part of compressed gas can enter the elastic pressure accumulation air bag through the first gas guide channel, and due to the existence of the one-way valve, the gas in the elastic pressure accumulation air bag can not flow back to the damping air chamber, so that the effect of continuously weakening the resilience of the damping air chamber to the right piston disc and the left piston disc is achieved, the phenomenon that the resilience is larger and larger after the damping air chamber is compressed is effectively prevented, and the damping and buffering process of the damping plate is more stable; when the damping plate moves upwards, the right piston disc and the left piston disc start to move away from each other under the resilience action of the first return spring and the second return spring, negative pressure is formed in the damping air chamber due to the increase of the volume, the resilience speed of the springs is weakened, the resilience vibration strength is reduced, and meanwhile, under the action of the negative pressure, air in the left air inlet cavity is guided into the damping air chamber through the left one-way valve; the air in the right air inlet cavity is guided into the damping air chamber through the right one-way valve, and the normal pressure state in the damping air chamber is maintained; meanwhile, external air can be supplemented into the left air inlet cavity and the right air inlet cavity through the vent grooves, the left air inlet channel and the right air inlet channel;
the air in the air bag expansion cavity can reach the pressure relief threshold value of the pressure relief valve continuously after the elastic pressure accumulating air bag expands gradually, the pressure relief valve can be opened continuously due to continuous air inflow in the air bag expansion cavity, so that the air in the air bag expansion cavity with relatively constant expansion size can continuously flow into the air collection cavity in the air box through the air guide channel, and further the air collection cavity can form stable positive pressure, and the elastic pressure accumulating air bag structure can avoid the phenomenon that the air pressure in the air collection cavity is unstable due to the fact that the first air guide channel is directly connected with the air collection cavity; finally, the pressure-accumulating gas in the wind collecting cavity is blown to the chest of the runner in a wind mode through the plurality of air outlet holes, and then the wind blowing effect on the sportsman is achieved.
Has the advantages that: the damping air chamber has a simple structure, and the damping air chamber is adopted, so that the damping process is more stable; the rebound process is softer; the vibration intensity is reduced; meanwhile, part of the impact energy is used for continuously supplementing air to the air bag, and the air blowing effect on the sportsman is further achieved.

when the damping plate 27 is displaced downwards due to the impact of foot pedal, the two connecting rods 28 are driven by the downward displacement of the damping plate 27 to drive the two sliding rings 10 to respectively move to gradually approach the hollow cylinder 30, the right piston push rod 17 and the left piston push rod 15 are driven by the two sliding rings 10 to respectively move to approach the right piston disc 20 and the left piston disc 29, the gas in the damping air chamber 4 is rapidly compressed due to the approaching motion between the right piston disc 20 and the left piston disc 29, and the compressed gas in the damping air chamber 4 cannot instantly enter the elastic pressure accumulation air bag 42 through the first gas guide channel 26 due to the action of the flow limiting cylinder 100, so that the damping air chamber 4 forms the rebound force to the right piston disc 20 and the left piston disc 29, thereby playing a role in buffering and inhibiting the tendency that the right piston disc 20 and the left piston disc 29 continue to approach each other, and further playing a role in buffering role in the downward movement of the damping plate 27, because the gas in the damping air chamber 4 is gradually compressed, part of the compressed gas can enter the elastic pressure accumulation air bag 42 through the first gas guide channel 26, and because of the existence of the one-way valve 103, the gas in the elastic pressure accumulation air bag 42 can not flow back to the damping air chamber 4, so that the effect of continuously weakening the resilience force of the damping air chamber 4 on the right piston disc 20 and the left piston disc 29 is achieved, the phenomenon that the resilience force of the damping air chamber 4 is increasingly larger after being compressed is effectively prevented, and the damping and buffering process of the damping plate 27 is more stable; when the damping plate 27 moves upwards, under the rebounding action of the first return spring 34 and the second return spring 3, the right piston disc 20 and the left piston disc 29 start to move away from each other, at this time, a negative pressure is formed in the damping air chamber 4 due to the increase of the volume, the rebounding speed of the springs is weakened, the rebounding vibration strength is reduced, and meanwhile, under the action of the negative pressure, the gas in the left air inlet cavity 13 is guided into the damping air chamber 4 through the left check valve 1; the gas in the right gas inlet cavity 7 is introduced into the damping gas chamber 4 through the right one-way valve 8, and the normal pressure state in the damping gas chamber 4 is maintained; meanwhile, external air is supplemented into the left air inlet cavity 13 and the right air inlet cavity 7 through the vent grooves 18, the left air inlet channel 36 and the right air inlet channel 9;
along with the continuous running of the running sportsmen, air is continuously introduced into the elastic pressure-accumulating air bag 42, so that the elastic pressure-accumulating air bag 42 gradually expands, after the elastic pressure-accumulating air bag 42 gradually expands to a preset size, the air pressure in the air bag expansion cavity 49 can reach the pressure relief threshold value of the pressure relief valve 46, because the air can continuously enter the air bag expansion cavity 49, the pressure relief valve 46 can be continuously opened, so that the air in the air bag expansion cavity 49 with relatively constant expansion size can continuously flow into the air collecting cavity in the air box 69 through the air guide channel 44, so that stable positive pressure is formed in the air collecting cavity, and the structure of the elastic pressure-accumulating air bag 42 can avoid the phenomenon that the first air guide channel 26 is directly connected with the air collecting cavity, so that the air pressure in the air collecting cavity is unstable; finally, the pressure-accumulating gas in the wind collecting cavity is blown to the chest position of the runner in a wind mode through the plurality of air outlet holes 68, and then the wind blowing effect on the sportsman is achieved.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
