The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1 to 3, the explosion-proof energy feedback tire disclosed by the invention comprises a tire body 1, wherein the tire body 1 is divided into 16 mutually independent pneumatic cylinders 2, and the tire body 1 is divided into air in the pneumatic cylinders 2 and air outside the pneumatic cylinders 2 in the tire body. The outer circumferential wall of the tire body 1 is the bottom of each pneumatic cylinder 2, and the air inside the tire body outside the pneumatic cylinder 2 is located between the pneumatic cylinder 2 and the rim. The tyre also comprises a rim shaft, two circles of stator rings 12 are fixed on two sides of the rim shaft, and a rotor gear ring 9 is arranged between the two circles of stator rings 12 through a roller bearing 13, and the figure 2 is shown.

The 16 pneumatic cylinders 2 are arranged along the circumference of the tire body 1, the pneumatic cylinders 2 are mutually independent, a piston assembly and a return spring 7 are installed in each pneumatic cylinder 2, the piston assembly is arranged at the end part of one side, facing the circle center, of each pneumatic cylinder 2, the piston assembly comprises a piston cylinder 3, a piston rod 5 and a push rod head 4, the piston rod 5 can slide in the piston cylinder 3 along the radial direction of the tire body, the push rod head 4 is installed on the piston rod 5, and ratchet teeth 6 are arranged on the outer edge of a rotor gear rim 9, so that air outside the pneumatic cylinders 2 in the tire body is located between the pneumatic cylinders 2 and the ratchet teeth. When the tyre body 1 is pressed by force, the push rod head 4 of the piston assembly is in matched contact with the inclined surface of the ratchet wheel teeth 6, and the push rod head 4 is used for pushing the ratchet wheel teeth 6 on the rotor gear rim 9.

The return spring 7 is installed between the piston assembly and the pneumatic cylinder 2, i.e. one end is fixed at the bottom end of the piston rod 5 and the other end is fixed at the bottom surface of the pneumatic cylinder 2.

The tire is provided with two one-way air-operated valves, which are referred to as a one-way air-operated valve a10 and a one-way air-operated valve B11, respectively. The unidirectional air-operated valves a10 and B11 are used to adjust the relative relationship between the internal air pressure of the air cylinder 2 and the air pressure of the outer space of the air cylinder 2 in the tire case 1. The unidirectional air-operated valve a10 functions to exhaust air from the outside of the cylinder block 2 to the inside of the cylinder block 2, and the unidirectional air-operated valve B11 functions to exhaust air from the inside of the cylinder block 2 to the inside of the tire case 1 outside the cylinder block 2.

Ratchet tooth 6, the appearance form is similar to the ratchet, 6 wherein sides of ratchet tooth are the inclined plane, and the contained angle is less than 45 degrees between inclined plane and the horizontal plane, and the side that putter

head

4 and 6 inclined planes of ratchet tooth correspond is parallel, when piston rod 5 promoted putter head 4 and moves to centre of a circle direction, 4 inclined planes of putter head and the contact extrusion of 6 inclined planes of ratchet tooth. The included angle of the top ends of the ratchet teeth 6 is 90 to 120 degrees, and the length of the inclined surface of one side of the ratchet teeth 6, which is contacted with the push rod head 4, is longer than that of the inclined surface of the other side.

In the embodiment, the tops of the ratchet teeth 6 and the top of the push rod head 6 are chamfered by machining, so that the abrasion between the teeth in the movement process is reduced, and a large pushing component force is provided.

In this embodiment, 32 ratchet teeth 6 are installed on the rotor gear rim 9, and the rotor gear rim 9 itself is fixed by the cylindrical roller bearing 13 and installed in the middle of the rim outer ring to ensure that the rotor gear rim 9 and the tire body 1 and other components maintain different rotating speeds, and a plurality of small holes 8 are drilled on the side surface of the rotor gear rim 9 for installing and fixing the coil winding of the rotor. As shown in fig. 2, the moving rotor rim 9 is mounted in the middle of the rim shaft by means of cylindrical roller bearings 13, while the two sides fix two rings of stator rings 12 along the periphery of the hub.

The working process of the invention is as follows:

referring to fig. 4, 5 and 6, when the car is in a stationary state (fig. 4), the tire body 1 is deformed due to the self weight of the car, but the rotor rim 9 and the stator ring 12 do not move relatively, so that no current is generated.

At the beginning of the operation, the vehicle starts moving from a rest condition, and during the contact of the first pneumatic cylinder 2 with the ground (fig. 5), heat is generated by friction with the ground, while the volume of the pneumatic cylinder 2 is relatively reduced, and the internal gas temperature increases, the volume decreases, and therefore the internal gas pressure increases, according to the ideal gas pressure formula pV = nRT (p is the gas pressure, V is the gas volume, n is the amount of gaseous matter, R is a constant, and T is the temperature). The pressure difference is generated with the air in the tire body outside the pneumatic cylinder 2, the pressure difference pushes the piston rod 5 to slide in the piston cylinder 3 towards the direction close to the ratchet teeth 6, so that the push rod head 4 fixed on the upper part of the piston rod 5 is contacted with the ratchet teeth 6 on the rotor gear rim 9, and applies force to the ratchet teeth 6, the force is decomposed into a component force which is upward along the contact surface of the ratchet teeth 6 and is used for overcoming the friction force, and the component force which is vertical to the contact surface pushes the rotor gear rim 9 to move. When the contact area is reduced by a peak, the compressed return spring 7 quickly pulls the pusher head 4 back. One working cycle is as follows: the contact area of the first pneumatic cylinder 2 and the ground is from 0 to the maximum, and then to 0, the push rod head 4 on the piston rod 5 also completes one time of no contact to maximum pushing force supply, and then to the separation process, and the second pneumatic cylinder 2 also enters the working mode along with the completion of the contact of the first pneumatic cylinder 2 and the ground. In a repeated way, the rotor gear rim 9 is pushed to move, so that the speed of the rotor gear rim 9 and the speed of the tyre body 1 are ensured to be different although the rotor gear rim 9 and the tyre body are in a moving state, namely: there is a relative velocity. The stator ring 12 is fixedly arranged on the rim and has the same speed as the tyre body 1, so the speed of the stator ring 12 is different from that of the rotor gear ring 9, and the magnetic induction lines can be cut all the time to generate current in the working process. The current is stored in the vehicle-mounted storage battery through the lead, the cutting of the magnetic induction line to generate the current and the storage of the current in the battery are both the prior art and are not the key points of the invention which need to be protected, and the details are not described herein.

Because of friction and other factors, the relative speed of the control rotor gear ring 9 relative to the tire body 1 and the rim upper stator ring 12 is not too high because the tire speed is higher.

Considering that the road surface is uneven, influence factors such as deceleration strips, potholes and stones exist, the deformation amount of the tire body 1 is overlarge, and the unidirectional pneumatic valve B11 is additionally arranged at the edge of each pneumatic cylinder 2. When the deformation quantity is too large, the pressure in the cylinder body 2 is too large, the threshold value of the one-way pneumatic valve B11 is triggered, the one-way pneumatic valve B11 is automatically opened, air is exhausted to the space in the tire where the pneumatic cylinder 2 is removed, if the one-way pneumatic valve A10 detects that the pressure in the space in the tire where the pneumatic cylinder 2 is removed is too large, the threshold value is triggered, the one-way pneumatic valve A10 is automatically opened, so that the pressure problem is relieved, the pressure is prevented from being too large, damage is caused to the tire body 1, and even the tire is blown out.

When sharp objects such as nails appear on the road surface, the tire puncture causes the tire body 1 to have a gap 15, and air leakage appears, referring to the attached figure 7, namely: one cylinder 2 starts to leak. The pressure in the space of the pneumatic cylinder 2 in the tire reversely pushes the push rod head 4 for puncturing the tire to be tightly attached to the piston assembly, and the piston cylinder 3 and the piston rod 5 in the piston assembly are good in sealing effect and cannot flow gas inwards. While the one-way pneumatic valve B11 needs to reach a threshold to open for gas to flow in. In summary, the pneumatic cylinder 2 containing air leakage holes is no longer supplied with air inside the tire body 1, and the tire body does not participate in the operation, and the automobile can still run normally.

The above embodiments are merely illustrative of the technical concepts and features of the present invention, and the purpose of the embodiments is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
