Detailed Description
In view of the above technical features, the main effects of the adaptive inflation-free tire of the present invention will be apparent from the following examples.
Referring to fig. 1 to 3, a first embodiment of an adaptive inflation-free tire 100 of the present invention is disclosed, comprising: a tyre body 1, an adjustable damper 2, a sensing unit 3 and a control unit 4. The tyre body 1 is a inflation-free tyre, so as to avoid the problems of pressure loss, tyre burst, carcass resonance and cavity resonance of the inflation tyre.
The tire body 1 comprises a tread 11, an inner rim 12, and a plurality of spokes 13, wherein the spokes 13 are disposed on the inner side (side) and the outer side (side) of the tire body 1, each spoke 13 has a first segment 131 pivotally connected to the tread 11, and a second segment 132 pivotally connected to the inner rim 12, more specifically, the tread 11 has a first fixing layer 14, the first fixing layer 14 has a first receiving slot 141 for receiving a first supporting portion 15, the inner rim 12 has a second fixing layer 16, the second fixing layer 16 has a second receiving slot 161 for receiving a second supporting portion 17, the first segment 131 of the spoke 13 is pivotally connected to the first supporting portion 15, and the second segment 132 of the spoke 13 is pivotally connected to the second supporting portion 17. The first supporting portion 15 has a first groove 151, the second supporting portion 17 has a second groove 171, and a first fixing member 18 is disposed in the first groove 151, and a second fixing member 19 is disposed in the second groove 171, so that the first supporting portion 15 and the second supporting portion 17 are respectively fixed on the first fixing layer 14 of the tread 11 and the second fixing layer 16 of the inner ring 12. The first fixing element 18 and the second fixing element 19 may be C-shaped rings or belts, etc., the first fixing layer 14 and/or the second fixing layer 16 may have a rough surface, and the first fixing layer 14 may be formed integrally with the tread 11 during vulcanization, or may be combined with the tread 11 in a sleeved manner like the second fixing layer 16 and the inner ring 12. The inner rim 12 may also be a conventional rim or may be formed directly integrally with the tire body 1. In practical implementation, the tire body 1 may further include an outer cover (not shown) adjacent to the spokes 13, and by means of the outer cover, the spokes 13 can be protected from being damaged by foreign objects like a shield, so as to maintain running safety of the tire body 1.
The adjustable damper 2 is pivotally connected to the first segment 131 and the second segment 132 of the spoke 13, so that the first segment 131 and the second segment 132 can be bent relatively to form an angle, and the angle can be changed between 30 degrees and 150 degrees. The bending direction of the spokes 13 on one side of the tire body 1 faces one of the counterclockwise direction or the clockwise direction, and the bending direction of the spokes 13 on the other side of the tire body 1 faces the other of the counterclockwise direction or the clockwise direction, the spokes 13 on the inner side (inside) and the outer side (outside) of the tire body 1 face opposite directions to each other, and misalignment of the tread 11 and the inner rim 12 can be avoided during driving and braking, thereby increasing the overall structural stability of the tire body 1.
The sensing unit 3 may be disposed at a joint of the spoke 13, an inner surface of the tread 11, or an axle (not shown) of a vehicle (not shown), such as a six-component meter, for example, to accurately measure three-direction force and moment. The sensing unit 3 firstly measures a pressed state of the tyre body 1 under various road conditions by means of an accelerator, and the accelerator can sense the difference sharply if the tyre body is in rugged, rough, ponding and other road surfaces; or the sensing unit 3 such as a vehicle image sensor detects the road surface condition in advance, and then the pressed state or the road surface condition is transmitted to the control unit 4 for judgment in a wireless signal transmission mode, and the normal operation of all joints can be ensured by the accelerator. In practice, the power of the adjustable damper 2 and the sensing unit 3 can be supplied from the vehicle mounted with the adaptive inflation-free tire 100 in a wired or wireless manner.
Referring to fig. 3 to 5, the adjustable damper 2 includes a rotary shaft 21, a stator 22, a rotor 23, a solenoid 24 and a damping oil 25. The adjustable damper 2 is pivotally connected to the first segment 131 and the second segment 132 of the spoke 13, so that the first segment 131 and the second segment 132 can be bent relatively to form an angle. In practical implementations, the angle may vary between 30 degrees and 150 degrees. The stator 22 is provided on the rotation shaft 21. The rotor 23 is disposed in the stator 22 and is sleeved on the rotating shaft 21. The electromagnetic coil 24 is disposed in the stator 22. The damping oil 25 is filled in the stator 22 and separates the rotor 23 and the stator 22, and the damping oil 25 includes a magnetic body 251, the magnetic body 251 being shown for simplicity. Bearings or other auxiliary structures can be added between the rotating shaft 21, the stator 22, the rotor 23 and the electromagnetic coil 24 according to practical situations, so that abrasion is reduced, and the service life of the adjustable damper 2 is prolonged.
Referring to fig. 5 and 6, and referring to fig. 2, the control unit 4 determines the pressed state or vehicle image sensing according to the acceleration variation obtained by the sensing unit 3, detects the road condition in advance, and changes the electromagnetic field in the adjustable damper 2 according to the pressed state or the road condition detection result, for example, by means of wireless control, so as to control the arrangement of the magnetic body 251 of the damping oil 25, and in practical implementation, the sensing unit 3 itself may also have a microprocessor or the like capable of determining the pressed state, so as to directly determine on the sensing unit 3, and then transmit the pressed state to the control unit 4 to control the adjustable damper 2. More specifically, the electromagnetic field in the adjustable damper 2 refers to the magnetic field generated by the electromagnetic coil 24. When the magnetic field of the electromagnetic coil 24 is not activated, the magnetic body 251 is randomly dispersed in the damping oil 25; when the control unit makes the magnetic field of the electromagnetic coil 24 act, the magnetic bodies 251 are aligned along the magnetic force line direction, so as to change the damping of the damping oil 25.
Referring to fig. 1 and 6, the adjustable damper 2 can be used to adjust the damping of the adaptive inflation-free tire 100 in good time to meet the driving condition. For example, since the road surface is often rough, the adaptive inflation-free tire 100 can increase damping in good time after being impacted during traveling on rough road, so as to quickly attenuate vibration and improve comfort and calm; while driving at a high speed, for example, at a speed of 80 km/h or more, the adaptive inflation-free tire 100 can reduce the energy consumption of the tire body 1 due to rolling by reducing the electromagnetic field and the damping of the damper, reduce the temperature rise of the tire body 1, delay the fatigue and aging of the material of the tire body 1, and improve the durability; the resonance frequency of the tire body 1 can be raised when the damping is low, the resonance frequency of the tire body 1 can be lowered when the damping is high, the running resonance is avoided, and the comfort and the calm degree are improved. When the damping of the adaptive inflation-free tire 100 is reduced, the rolling resistance is also directly reduced, thereby achieving the energy-saving effect.
Referring to fig. 7, a second embodiment of the adaptive inflation-free tire of the present invention is disclosed, which is different from the first embodiment in that: in the first embodiment [ the first embodiment is shown in fig. 3], the adjustable damper 2 is pivotally connected between the first segment 131 and the second segment 132 of the spoke 13; in the present embodiment, the adjustable damper 2a is pivotally connected between the first segment 131a of the spoke 13a and the tread 11 a.
The first segment 131a and the second segment 132a of the spoke 13a are pivoted to each other, and similar to the first embodiment, the first segment 131a and the second segment 132a of the spoke 13a can be bent relatively to form the angle. By means of the adjustable damper 2a, the damping of the adaptive inflation-free tire 100a can be adjusted in good time to meet the driving condition. The rest of the structure is the same as that of the first embodiment, and will not be described again.
Referring to fig. 8, a third embodiment of the adaptive inflation-free tire of the present invention is disclosed, which is different from the first embodiment in that: in the first embodiment [ the first embodiment is shown in fig. 3], the adjustable damper 2 is pivotally connected between the first segment 131 and the second segment 132 of the spoke 13; in the present embodiment, the adjustable damper 2b is pivotally connected between the second segment 132b of the spoke 13b and the inner ring 12 b.
The first segment 131b and the second segment 132b of the spoke 13b are pivoted to each other, and similar to the first embodiment, the first segment 131b and the second segment 132b of the spoke 13b can be bent relatively to form the angle. By means of the adjustable damper 2b, the damping of the adaptive inflation-free tire 100b can be adjusted in good time to meet the driving condition. The rest of the structure is the same as that of the first embodiment, and will not be described again.
Referring to fig. 9 and 10, a fourth embodiment of the adaptive inflation-free tire of the present invention is disclosed, which is different from the first embodiment in that: in the first embodiment [ the first embodiment is shown in fig. 3 and 5], the adjustable damper 2 is pivotally connected between the first segment 131 and the second segment 132 of the spoke 13, and the adjustable damper 2 comprises a rotation shaft 21, a stator 22, a rotor 23, an electromagnetic coil 24 and damping oil 25; in the present embodiment, the adjustable damper 2c is coupled between the second segment 132c of the spoke 13c and the inner ring 12c, and the adjustable damper 2c includes the electromagnetic coil 24c and the damping oil 25c.
The damping oil 25c is flow-filled in the adjustable damper 2c, and the magnetic body 251c is also contained in the damping oil 25c. The first segment 131c of said spoke 13c is then connected to the tread 11c. By changing the electromagnetic field generated by the electromagnetic coil 24c to control the arrangement of the magnetic bodies 251c of the damping oil 25c, the damping of the adjustable damper 2c can be changed to satisfy the running condition.
When the electromagnetic coil 24c does not generate an electromagnetic field, the magnetic body 251c is randomly distributed in the damping oil 25c. At this time, the damping of the adjustable damper 2c is restored to a normal state.

In this embodiment, the elastic body 5d has a plurality of through holes 51d, and a coupling member (not shown), such as a screw, can pass through the through holes 51d to couple the elastic body 5d to the spoke 13d. In addition to the adjustable damper 2d, the elastic body 5d can provide the rigidity of the spoke 13d, so as to solve the problem that the adjustable damper 2 only contains damping oil 25 and is limited by the size of the adjustable damper 2, but cannot provide a rigid mechanism, thereby better meeting the driving condition.
While the fourth embodiment is actually implemented [ the fourth embodiment is shown in fig. 9], the fourth embodiment may also be combined with the elastic body 5d such as a spring to provide the fixing rigidity of the spoke 13c, which is not shown in the drawings.
