The triggering process of the elastic pulling mechanism is as follows: when the target area on the outer surface of the tire is in contact with the ground, the target area of the tire is deformed due to the weight of the automobile, and then the steel wire rope connected in the target area releases a relaxation amount equivalent to the deformation amount; since the second spring continuously applies a pulling force to the slider, the slider slides along the path defined by the first slider mounting interval or the second slider mounting interval by a distance equivalent to the deformation amount under the action of the pulling force, so that the steel wire rope always maintains a taut state; During the sliding process of the slider in the first slider mounting interval, the slider slides from the gradual groove A of the ratchet control ring A to the inner hole wall of the ratchet control ring A; during the sliding process of the slider in the second slider mounting interval, the slider slides from the gradual groove B of the ratchet control ring B to the inner hole wall of the ratchet control ring B; the change from power separation to power engagement is realized; The restoring process of the elastic pulling mechanism is as follows: when the target area on the outer surface of the tire is separated from the ground, the target area that has been deformed previously rebounds and restores due to the action of the air pressure in the tire cavity, and at the same time, the steel wire rope connected in the target area is pulled to move radially outward by a distance equivalent to the deformation amount, and the slider is pulled to slide along the path defined by the first slider mounting interval or the second slider mounting interval by a distance equivalent to the deformation amount; During the sliding process of the slider in the first slider mounting interval, the slider slides from the inner hole wall of the ratchet control ring A to the gradual groove A of the ratchet control ring A; during the sliding process of the slider in the second slider mounting interval, the slider slides from the inner hole wall of the ratchet control ring B to the gradual groove B of the ratchet control ring B; the change from power engagement to power separation is realized.

[0012] Compared with the prior art, the present application has the following advantages: 1. It integrates power generation devices into the inside of automobile tires, generates electricity by using the deformation energy and rotational kinetic energy of the tires during driving, specifically converts the tire ground deformation into electrical energy by combining the ratchet mechanism with electromagnetic induction, and realizes continuous power generation by combining the continuous rotation characteristics of the driving tire.

[0013] 2. High energy recovery, breaking through the energy efficiency bottleneck: solve the problem of deformation energy and friction heat dissipation of traditional tires. When the tire is deformed, the steel wire rope pulls the sliding block, triggers the engagement of the ratchet and the rotor ratchet section, and when the tire rebounds, the ratchet and the rotor ratchet section are separated, forming intermittent transmission. The rotor cuts the magnetic field to generate electricity, converting mechanical loss into usable electrical energy, which can be directly supplied to the vehicle battery, relieving the endurance pressure of electric vehicles.

[0014] 3. Compact structure, safety and compatibility: The protection ring (diameter less than 16-24mm of the bead diameter) of the end protection plate contacts the ground first when the tire bursts, reducing the sudden drop in tire diameter and reducing the risk of vehicle rollover. The n-shaped bead and u-shaped steel ring form a closed air chamber to protect the power generation components from dust / water vapor erosion.

[0015] 4. Precise trigger of power engagement, reducing additional energy consumption: The elastic pulling mechanism (steel wire rope + second spring) responds to tire deformation in real time; the steel wire rope is released when the tire is grounded → the sliding block slides → the ratchet engages the rotor; when the tire rebounds, the steel wire rope is tightened → the sliding block resets → the ratchet retracts and separates from the rotor. The advantage of this structure is that it only generates electricity when the tire is deformed, avoiding idle friction loss and prolonging the service life of the device.

[0016] 5. Double-zone staggered layout to improve power generation efficiency: The first and second elastic pulling mechanisms are alternately staggered, covering the 360° circumference of the tire. When the tire rolls one circle, the two elastic pulling mechanisms are triggered alternately, achieving high-frequency energy capture.

[0035] Preferably, the rotor 3 sleeve ring section 31 is made of permanent magnet material or an annular permanent magnet is embedded in the inner hole of the rotor 3 sleeve ring section 31; and correspondingly, an induction coil is wound on the coil winding column 21.

[0036] Preferably, it further comprises end guards 8. The end guard 8 is an annular plate provided with a central hole, and two end guards 8 are respectively sleeved on the steel ring 12 through the central holes thereof and located on the two axial sides of the steel ring 12, and are fixedly connected with the steel ring 12, and the energy recovery device and the dynamic-static cooperation assembly are clamped between the two end guards 8. The radially outer side edges of the two end guards 8 are respectively provided with axially extending protection rings 81, and the protection rings 81 of the two end guards 8 are oppositely arranged and have the same outer diameter as the protection rings 81. The diameter of the protection ring 81 of the end guard 8 is 16-28 mm smaller than the inner diameter of the bead. Based on this feature, when a tire burst accident occurs to the automobile during driving, the protection rings 81 of the two end guards 8 will first directly come into rolling contact with the ground, and the tire diameter is only reduced by 16-28 mm, and the angle of inclination of the vehicle due to the reduction of the tire diameter after the tire burst is smaller than that of the conventional tire, thereby reducing the risk of automobile rollover and improving the driving safety of the automobile.

[0037] Preferably, the number of bearings 500 is two, and the two bearings 500 are sleeved on the outer circumferential surface of the stator 2 and located on the two sides of the coil winding column 21, the inner rings of the two bearings 500 are fixedly connected with the stator 2, and the outer rings of the two bearings 500 are fixedly connected with the sleeve ring segment 31 of the rotor 3; based on the arrangement of the two bearings 500, the stator 2 and the rotor 3 can rotate relative to each other and do not interfere with each other.

[0038] Preferably, the steel ring 12 is formed by splicing a left half steel ring part and a right half steel ring part, the inside of the left half steel ring part is provided with a radially extending threading passage, one end of the threading passage located on the radially outer side is an entry end, and one end of the threading passage located on the radially inner side is an exit end 121; after the one ends of all the induction coils are gathered, the one ends enter the threading passage through the entry end and then exit the threading passage from the exit end 121.

[0039] The above-mentioned tire with power generation function can automatically generate electricity during the driving of the automobile. Since all the outer ends of the steel wire ropes 71 in the two sets of elastic pulling mechanisms are connected to the tire bead 11 in a ring shape around the outer circumferential surface of the tire bead 11, as the tire rolls, when a certain area on the outer circumferential surface of the tire is in contact with the ground, the corresponding elastic pulling mechanism connected to the steel wire rope in the area is triggered, and when the area is separated from the ground, the corresponding elastic pulling mechanism connected to the steel wire rope in the area is restored. Thus, during the driving of the automobile, the elastic pulling mechanisms are sequentially and temporarily triggered as the tire rolls on the ground. During the time period when a certain set of elastic pulling mechanisms is triggered, the ratchet 61 in the set of elastic pulling mechanisms hooks the teeth on the ratchet wheel section 32 of the rotor 3, thereby achieving temporary power engagement. When the set of elastic pulling mechanisms is restored, the ratchet 61 in the set of elastic pulling mechanisms is not in contact with the ratchet wheel section 32 of the rotor 3. Ultimately, as the tire continuously rolls, intermittent power engagement is achieved. During the power engagement process, the stator 2 and the rotor 3 rotate relative to each other, causing the induction coil to cut the magnetic lines and generate an induced current, which is output from the wire outlet of the wire passage, achieving the purpose of generating electricity.

[0040] The triggering process of the above-mentioned elastic pulling mechanism is as follows: when the target area on the outer circumferential surface of the tire is in contact with the ground, the target area of the tire is deformed (slightly inwardly depressed) due to the weight of the automobile, and then a small amount (equivalent to the deformation amount) of slack is released from the connected steel wire rope in the target area. Since the second spring continuously applies tension to the slider 5, the slider 5 slides a small distance (equivalent to the deformation amount) along the path defined by the first slider mounting interval 100 or the second slider mounting interval 200 under the action of the tension, thereby keeping the steel wire rope in a taut state.

[0041] During the sliding of the slider 5 in the first slider mounting interval 100, the slider 5 slides from the gradual change groove A421 of the ratchet control ring A42 to the inner hole wall of the ratchet control ring A42, and during the sliding of the slider 5 in the second slider mounting interval 200, the slider 5 slides from the gradual change groove B461 of the ratchet control ring B46 to the inner hole wall of the ratchet control ring B46. This achieves the change from power disengagement to power engagement.

[0042] The restoration process of the above-mentioned elastic pulling mechanism is as follows: when the target area on the outer circumferential surface of the tire is separated from the ground, the previously deformed target area rebounds due to the pressure in the tire cavity 400, and at the same time, the connected steel wire rope in the target area is pulled to move a small distance (equivalent to the deformation amount) radially outward of the tire, and the slider 5 is pulled to slide a small distance (equivalent to the deformation amount) along the path defined by the first slider mounting interval 100 or the second slider mounting interval 200.

[0043] During the sliding process of the slider 5 in the first slider installation section 100, it slides from the inner hole wall of the ratchet control ring A42 to the gradual change groove A421 of the ratchet control ring A42. During the sliding process of the slider 5 in the second slider installation section 200, it slides from the inner hole wall of the ratchet control ring B46 to the gradual change groove B461 of the ratchet control ring B46, thus achieving the change from power engagement to power disengagement.
