[0011] This utility model has the following advantages compared with the prior art: 1. It integrates the power generation device into the inside of the car tire, and generates electricity by utilizing the deformation energy and rotational kinetic energy of the tire while the car is in motion. Specifically, it converts the tire's ground deformation into electrical energy through a combination of ratchet mechanism and electromagnetic induction. Combined with the characteristic of the car tire continuously rotating while in motion, it achieves continuous power generation.

[0012] 2. High-efficiency energy recovery, breaking through energy efficiency bottlenecks: Solving the problem of deformation energy and frictional heat dissipation in traditional tires. When the tire deforms upon contact with the ground, a steel cable pulls a slider, triggering the ratchet to engage with the rotor ratchet segment. When the tire rebounds and returns to its original position, the ratchet separates from the rotor ratchet segment, forming an intermittent transmission. The rotor's rotation cuts the magnetic field to generate electricity, converting mechanical losses into usable electrical energy that can be directly supplied to the vehicle's battery, alleviating the range anxiety of electric vehicles.

[0013] 3. Compact structure, balancing safety and compatibility: The protective ring of the end plate (16-24mm smaller in diameter than the tire bead diameter) contacts the ground first in the event of a tire blowout, reducing the sudden drop in tire diameter and lowering the risk of vehicle rollover. The N-shaped tire bead and U-shaped steel rim form a closed air chamber, protecting the energy replenishment and power generation components from dust / moisture corrosion.

[0014] 4. Precise power engagement triggering reduces additional energy consumption: The elastic traction mechanism (steel wire rope + second spring) responds to tire deformation in real time; upon ground contact, the slack in the steel wire rope is released → the slider slides → the ratchet protrudes and engages the rotor; upon lift-off, the tire rebounds, tightening the steel wire rope → the slider resets → the ratchet retracts and separates from the rotor. The advantage of this structure is that it generates electricity only when the tire deforms upon contact with the ground, avoiding idling friction losses and extending the service life of the device.

[0015] 5. Dual-zone staggered layout to improve power generation efficiency: The first and second sets of elastic traction mechanisms are arranged alternately and staggeredly to cover the 360° circumference of the tire. When the tire rolls one revolution, the two sets of elastic traction mechanisms are triggered alternately to achieve high-frequency energy capture.

The power input component is fixedly connected to the annular groove A of the tire bead 11, and the power output component engages or disengages from the ratchet section 32 of the rotor 3. When the connection between the power input component and the tire bead 11 is recessed inward, the power input component transmits the recessed stroke to the power output component through the elastic connection, temporarily engaging the power output component with the ratchet section 32 of the rotor 3. When the connection between the power input component and the tire bead 11 returns to its original state, the power input component transmits the rebound stroke to the power output component through the elastic connection, temporarily disengaging the power output component from the ratchet section 32 of the rotor 3.

The first slider mounting section 100 and the guide wheel mounting section 300 are connected at the lower end, and the guide wheel mounting section 300 and the second slider mounting section 200 are connected at the lower end. The outer circular surface of the intermediate block 44 has a rope hole that extends to its inner hole. The inner end face of the navigation end plate A41 has an arc-shaped groove A411. The inner end face of the navigation end plate B47 has an arc-shaped groove B471. The inner wall of the ratchet control ring A42 has a smoothly transitioning gradient groove A421. The inner wall of the ratchet control ring B46 is provided with a smoothly transitioning gradient groove B461.

[0025] There are two sets of elastic traction mechanisms. Each set of elastic traction mechanisms includes multiple sets of elastic traction mechanisms evenly distributed in a ring. The first set of elastic traction mechanisms is set in the tire air cavity 400, the first slider installation section 100 and the guide wheel installation section 300. The second set of elastic traction mechanisms is set in the tire air cavity 400, the second slider installation section 200 and the guide wheel installation section 300.

[0026] The elastic traction mechanism includes a slider 5, a ratchet drive assembly, and an elastic traction assembly.

[0027] The slider 5 is slidably mounted in the first slider mounting section 100 or the second slider mounting section 200 via an arc-shaped protrusion 51 on one side surface. When the slider 5 slides in contact with the arc-shaped groove A411 of the navigation end plate A41 via the arc-shaped protrusion 51, it is slidably mounted in the first slider mounting section 100. When the slider 5 slides in contact with the arc-shaped groove B471 of the navigation end plate B47 via the arc-shaped protrusion 51, it is slidably mounted in the second slider mounting section 200. The side surface of the slider 5 facing the ratchet section 32 of the rotor 3 is defined as the working surface 52, and the side surface of the slider 5 facing away from the ratchet section 32 of the rotor 3 is defined as the control surface 53. The slider 5 is provided with a mounting channel that connects the working surface 52 and the control surface 53. The mounting channel includes a ratchet mounting groove 54 and a pusher mounting hole 55 connected in sequence. The ratchet mounting groove 54 is directly connected to the working surface 52, and the pusher mounting hole 55 is directly connected to the control surface 53.

[0028] The ratchet drive assembly is installed inside the slider 5 and corresponds one-to-one with the slider 5. The ratchet drive assembly includes a ratchet 61, a torsion spring shaft 62, push blocks A63 and B64, and a first spring 65. The ratchet 61 is movably installed in the ratchet mounting groove 54 of the slider 5 via the torsion spring shaft 62. The toothed side of the ratchet 61 faces the outside of the ratchet mounting groove 54. The ratchet 61 rotates against the elastic force of the torsion spring shaft 62, causing its toothed side to extend out of the ratchet mounting groove 54 or retract into the ratchet mounting groove 54. The side of the ratchet 61 facing away from the toothed surface is defined as the back surface 611. Push blocks A63 and B64 are movably installed in the push block mounting holes 55 of the slider 5. One end of push block A63 abuts against the back surface 611 of the ratchet 61, and one end of push block B64 extends out of the control surface 53 and abuts against the inner wall of the ratchet control ring A42 or the inner wall of the ratchet control ring B46. The first spring 65 is compressed and set in the push block mounting hole 55 of the slider 5 and is located between push block A63 and push block B64.

[0029] When the slider 5 slides along the path defined by the first slider mounting section 100 to the inner wall of the ratchet control ring A42, the protruding end of the push block B64 is pushed back into the push block mounting hole 55 of the slider 5 by the inner wall of the ratchet control ring A42. The push block B64 pushes the ratchet 61 to rotate around the torsion spring shaft 62 through the first spring 65 and the push block A63, so that the toothed side of it extends out of the ratchet mounting groove 54, thereby hooking the teeth on the ratchet section 32 of the rotor 3 to achieve power engagement.

[0030] When the slider 5 slides along the path defined by the second slider mounting section 200 to the inner wall of the ratchet control ring B46, the protruding end of the push block B64 is pushed back into the push block mounting hole 55 of the slider 5 by the inner wall of the ratchet control ring B46. The push block B64 pushes the ratchet 61 to rotate around the torsion spring shaft 62 through the first spring 65 and the push block A63, so that the toothed side of it extends out of the ratchet mounting groove 54, thereby hooking the teeth on the ratchet section 32 of the rotor 3 to achieve power engagement.

[0031] When the slider 5 slides along the path defined by the first slider mounting section 100 to the gradient groove A421 of the ratchet control ring A42, the torsion spring shaft 62 forces the ratchet 61 to rotate into the ratchet mounting groove 54 of the retracting slider 5 through elastic force. At the same time as the ratchet 61 retracts, it pushes the end of the push block B64 out of the push block mounting hole 55 through the push block A63 and the first spring 65, thereby abutting against the gradient groove A421 to achieve power separation.

[0032] When the slider 5 slides along the path defined by the second slider mounting section 200 to the gradient groove B461 of the ratchet control ring B46, the torsion spring shaft 62 forces the ratchet 61 to rotate into the ratchet mounting groove 54 of the retracting slider 5 through elastic force. At the same time as the ratchet 61 retracts, it pushes the end of the push block B64 out of the push block mounting hole 55 through the push block A63 and the first spring 65, thereby abutting against the gradient groove B461 to achieve power separation.

[0033] The elastic tension assembly includes a steel wire rope 71, a guide wheel 72, a second spring 73, and a spring fixing plate 74. The outer end of the steel wire rope 71 is fixedly connected to the bottom surface of the annular groove A of the tire bead 11. The inner end of the steel wire rope 71 passes through the rope-passing hole of the intermediate block 44 into the guide wheel mounting section 300, then around the guide wheel 72, and finally is fixedly connected to the slider 5. The guide wheel 72 is rotatably mounted on the guide wheel mounting plate A43 or the guide wheel mounting plate B45 and located in the guide wheel mounting section 300. The second spring 73 is tensioned between the spring fixing plate 74 and the slider 5. Both ends of the second spring 73 are fixedly connected to the spring fixing plate 74 and the slider 5, respectively. The second spring 73 applies tension to the slider 5, thereby keeping the steel wire rope 71 taut. The spring fixing plate 73 is fixedly installed in the first slider mounting section 100 or the second slider mounting section 200.

[0034] Preferably, the rotor three ring segments 31 are made of permanent magnet material or a ring-shaped permanent magnet is embedded in the inner hole of the rotor three ring segments 31; correspondingly, an induction coil is wound on the coil winding column 21.

[0035] Preferably, it also includes end guards 8. The end guards 8 are annular plates with a central hole. Two end guards 8 are respectively fitted onto the steel ring 12 through their central holes, located on opposite axial sides of the steel ring 12, and fixedly connected to it. The energy recovery device and the dynamic-static mating assembly are sandwiched between the two end guards 8. Each of the two end guards 8 has an axially extending protective ring 81 at its radially outer edge. The protective rings 81 of the two end guards 8 are arranged opposite each other and have the same outer diameter. The diameter of the protective rings 81 of the end guards 8 is 16-28 mm smaller than the inner diameter of the tire bead. Based on this feature, when a tire blowout occurs while the vehicle is in motion, the protective rings 81 of the two end guards 8 will first directly roll into contact with the ground. The tire diameter will only decrease by 16-28 mm. After the blowout, the smaller reduction in tire diameter results in a smaller vehicle tilt angle compared to traditional tires, thus reducing the risk of vehicle rollover and improving driving safety.

[0036] Preferably, there are two bearings 500. Both bearings 500 are mounted on the outer circular surface of the stator 2 and located on both sides of the coil winding column 21. The inner rings of the two bearings 500 are fixedly connected to the stator 2, and the outer rings of the two bearings 500 are fixedly connected to the 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 without interfering with each other.

[0037] Preferably, the steel ring 12 is composed of a left half steel ring and a right half steel ring. The left half steel ring has a radially extending wire channel inside. The end of the wire channel located on the radially outer side is the wire inlet end, and the end of the wire channel located on the radially inner side is the wire outlet end. After all the induction coils are gathered at one end, they enter the wire channel through the wire inlet end and then exit the wire channel through the wire outlet end.

[0038] The aforementioned tire with power generation function replaces the tires of traditional automobiles, automatically generating electricity while the vehicle is in motion. Since the connection points of the outer ends of all the steel cables 71 in the two sets of elastic traction mechanisms to the tire bead 11 are evenly distributed in a ring around the outer surface of the tire bead 11, as the tire rolls, when a certain area on the outer surface of the tire contacts the ground, the corresponding elastic traction mechanism of the steel cable connected in that area is triggered; when that area leaves the ground, the corresponding elastic traction mechanism of the steel cable connected in that area returns to its original state. Thus, during vehicle operation, each set of elastic traction mechanisms is briefly triggered sequentially with each rotation of the tire on the ground. During the triggering period of a certain elastic traction mechanism, the ratchet 61 in that mechanism engages with the teeth on the ratchet section 32 of the rotor 3, achieving a brief power engagement. When a certain elastic traction mechanism returns to its original state, the ratchet 61 in that mechanism does not contact the ratchet section 32 of the rotor 3. The final effect is that intermittent power engagement is achieved as the tire continues to roll. During the power engagement process, the stator 2 and rotor 3 rotate relative to each other, causing the induction coil to cut the magnetic lines of force and generate an induced current. The induced current is output from the outlet end of the wire channel to achieve the purpose of power generation.

[0039] The triggering process of the above-mentioned elastic traction mechanism is as follows: When the target area on the outer surface of the tire contacts the ground, the target area of ​​the tire deforms (slightly indents inward) due to the weight of the car itself, which in turn causes the steel wire rope connected in the target area to release a small amount of slack (equivalent to the deformation). Since the second spring continuously applies a pulling force to the slider 5, under the action of the pulling force, the slider 5 slides a small distance (equivalent to the deformation) along the path defined by the first slider installation interval 100 or the second slider installation interval 200, so that the steel wire rope always remains taut.

[0040] During the sliding process of slider 5 in the first slider mounting section 100, it slides from the gradient groove A421 of the ratchet control ring A42 to the inner wall of the ratchet control ring A42. During the sliding process of slider 5 in the second slider mounting section 200, it slides from the gradient groove B461 of the ratchet control ring B46 to the inner wall of the ratchet control ring B46. This achieves the change from power separation to power engagement.

[0041] The above-mentioned elastic traction mechanism recovery process is as follows: When the target area on the outer surface of the tire is removed from the ground, due to the air pressure in the tire air cavity 400, the previously deformed target area rebounds and recovers. At the same time as rebounding and recovering, the steel wire rope connected in the target area is pulled to move a small distance (equivalent to the deformation) radially outward of the tire. The steel wire rope pulls the slider 5 to slide a small distance (equivalent to the deformation) along the path defined by the first slider installation interval 100 or the second slider installation interval 200.

[0042] During the sliding process of slider 5 in the first slider mounting section 100, it slides from the inner wall of the ratchet control ring A42 to the gradient groove A421 of the ratchet control ring A42. During the sliding process of slider 5 in the second slider mounting section 200, it slides from the inner wall of the ratchet control ring B46 to the gradient groove B461 of the ratchet control ring B46. This achieves the change from power engagement to power disengagement.
