Referring to fig. 1, in order to enhance the air flow supplement rate and strength of the outer tire 2, the number of the air charging chambers 6 is two, and the two air charging chambers 6 are symmetrically arranged around the central axis of the rim 1, and the air charging chambers 6 are provided with the anti-leakage balls 7, the return springs 8 and the sealing sleeves 9 for air flow supplement, so that the outer tire 2 can realize air flow supplement when rotating by one hundred eighty degrees, that is, the outer tire 2 can realize air charging twice during one rotation, and the air flow supplement rate of the outer tire 2 is enhanced.

Referring to fig. 2, in order to reinforce the condition that the outer tire 2 is under a low air pressure, a large amount of air flow can be supplemented, so that a cylindrical groove matched with the sealing sleeve 9 is formed in the inner wall of the protective sleeve 4, when the air flow pressure in the outer tire 2 is low, the movement stroke of the transmission rod 5 is increased, the sealing sleeve 9 can push the protective sleeve 4 away from the protective gasket 3, the protective sleeve 4 is elastically pulled up by force and away from the protective gasket 3, a large amount of air flow can be sucked by partially keeping away from the protective gasket 3, and in the next extrusion process, the air flow which is blown into the outer tire 2 in the inflation cavity 6 is greatly enhanced, meanwhile, because the protective sleeve 4 is made of a soft material, when the protective sleeve 4 is pushed by the sealing sleeve 9 to move outwards, the protective sleeve 4 bends outwards, further grasp the gland bush 9, not only guaranteed the sealing performance between its protective sheath 4 and the gland bush 9, still make the in-process that protective sheath 4 resumes at its transfer line 5 atress, because its protective sheath 4 is grasping the gland bush 9, therefore can lead to its transfer line 5 to be released, further promoted its intercommunication groove 11 with aerify chamber 6 and outer child 2 inner chamber communicate with each other, guaranteed that the air current of its aerify chamber 6 inner chamber can be whole to be acted on to the inner chamber of outer child 2, realized outer child 2 can be under the lower atmospheric pressure state big tolerance carry out the phenomenon of aerifing.

Referring to fig. 2, in order to realize that the transmission rod 5 is pushed by the outer tire casing 2, the communication groove 11 can firstly communicate the inflation cavity 6 with the inner cavity of the outer tire casing 2, so that the communication groove 11 is shaped like an i, the inflation cavity 6 is sealed with the inner cavity of the outer tire casing 2 through the inner wall of the sealing sleeve 9, and meanwhile, the center line of the top end of the communication groove 11 is located at the midpoint of the center line of the limiting rod 10, so that the communication groove 11 can be further taken out simultaneously when the limiting rod 10 extends out of the sealing sleeve 9, thereby ensuring the communication between the inflation cavity 6 and the inner cavity of the outer tire casing 2.

The using method (working principle) of the invention is as follows:

and (3) normal driving state: the rim 1 is fixedly arranged on a bicycle body, the whole bicycle is supported by the supporting framework 101, the rim 1 drives the outer tire casing 2 to rotate in the advancing process of the bicycle, and at the moment, the inner cavity of the outer tire casing 2 has proper air flow;

the automatic air supply state: referring to fig. 2, when the air pressure in the outer tire 2 is reduced, the outer tire 2 is gradually attached to the protective sleeve 4 in the direction of contacting the ground, and when the outer tire 2 approaches inwards, the outer tire 2 contacts the transmission rod 5 first and moves on the transmission rod 5 by being squeezed, and at the same time, the transmission rod 5 moves upwards, referring to fig. 3, when the communication groove 11 is communicated with the inner cavity of the inflation cavity 6, the limiting rod 10 pulls the sealing sleeve 9 to move upwards synchronously, because the anti-leakage ball 7 seals the air inlet groove 12 and the inflation cavity 6, when the transmission rod 5 is pressed, the air flow squeezed by the sealing sleeve 9 in the inflation cavity 6 is filled into the inner cavity of the outer tire 2 through the communication groove 11, so as to supplement the air flow, and at the same time, the sealing sleeve 9 above the outer tire moves upwards due to the transmission rod 5, the limiting rod 10 is further pushed to move upwards, at the moment, the communicating groove 11 is sealed by the sealing sleeve 9, in the process that the sealing sleeve 9 continuously moves upwards, the pressure in the inflating cavity 6 continuously decreases, the anti-leakage ball 7 overcomes the elastic force of the return spring 8 and moves upwards, the air flow in the air inlet groove 12 is enabled to flow into the inner cavity of the inflating cavity 6, after the air flow pressure in the inflating cavity 6 tends to be balanced with the outside, the anti-leakage ball 7 can seal the space between the air inlet groove 12 and the inflating cavity 6 through the elastic force of the return spring 8, in the process that the air flow in the inflating cavity 6 continuously rotates, the air flow in the inflating cavity 6 extrudes the transmission rod 5 through the outer tire 2 again, and the air flow in the inflating cavity 6 flows into the inner cavity of the outer tire 2 through the communicating groove 11, so that the air flow supplement of the inner cavity in the outer tire 2 is met;

meanwhile, when the air flow in the inner cavity of the outer tire 2 is seriously insufficient, the distance between the outer tire 2 and the protective sleeve 4 is shortened in the extrusion process, the movement stroke of the transmission rod 5 is further increased, the input amount of the air flow is increased, meanwhile, when the stroke of the transmission rod 5 is overlarge, in the process of pressing to promote the transmission rod 5 to be pushed upwards, the sealing sleeve 9 contacts the protective sleeve 4, the transmission rod 5 still can be pushed upwards, further, part of the protective sleeve 4 can be far away from the protective gasket 3 due to the pushing of the sealing sleeve 9, in the process of separating the protective sleeve 4, the inner cavity between the protective sleeve 4 and the protective gasket 3 is pulled up, the inner cavity of the inflation cavity 6 is further increased, the air flow filled into the inflation cavity 6 is greatly increased, and the air flow supplement is greatly performed in the process of low air pressure in the outer tire 2, the normal use of the outer tyre 2 in a low-pressure or low-weak air leakage state is met;

the outer tire 2 is in a state of a large tire burst or air leakage: at this moment, the air compensation amount in the inflation cavity 6 can not satisfy the outward output air flow in the outer tire 2 completely, so that the outer tire 2 can be directly attached to the side wall of the protective sleeve 4 in the pressurized process and can continuously run by extruding the protective sleeve 4, the use of the outer tire 2 can be still ensured even in the tire burst state, and the phenomenon that the outer tire 2 cannot be normally ridden due to large air leakage amount in the riding process can be prevented.
