Description

Technical Field

[0001] This application relates to the field of vehicle power supply, and in particular to a wireless power supply system, method, apparatus, and chip for wheel-end electrical equipment. Background Technology

[0002] As vehicles become increasingly intelligent, tire pressure monitoring systems, wheel-end sensors, air pumps, controllers, or other electrical devices can be installed at the wheel ends. Since these wheel-end electrical devices typically rotate with the wheel, and space at the wheel end is limited, providing a stable power supply to these devices becomes a problem that needs to be solved.

[0003] Because wheel-end components rotate, vibrate, and change position during vehicle operation, the structure supplying power to wheel-end electrical equipment may be affected by motion, installation space, and environmental factors, thereby affecting the power supply stability of wheel-end electrical equipment.

[0004] Meanwhile, the wheel end area typically also needs to house the rim, tire, braking components, sensors, air circuit components, and other structures. Adding a power supply component may increase the space occupied in the wheel end area and potentially affect the wheel's mass distribution. For scenarios requiring coordination with other functional components at the wheel end, the arrangement of the power supply structure with these other components will also increase design complexity.

[0005] Therefore, how to achieve power supply to wheel-end electrical equipment within the wheel-end space and reduce the impact of the power supply structure on the wheel-end space layout and wheel dynamic balance is a technical problem that needs to be solved. Summary of the Invention

[0006] This application provides a wireless power supply system, method, device, and chip for wheel-end electrical equipment, which can transmit electrical energy between non-rotating parts of a vehicle and rotating parts of the wheel end, thereby achieving efficient and stable power transmission to the wheel-end electrical equipment.

[0007] In a first aspect, this application provides a wireless power supply system for wheel-end electrical equipment. The system includes a power source, a transmitting wireless power supply component, a receiving wireless power supply component, and wheel-end electrical equipment. The power source is connected to the transmitting wireless power supply component. The transmitting wireless power supply component is disposed on a non-rotating part of the vehicle and is connected to the power source. The receiving wireless power supply component is disposed on a rotating part of the wheel end that rotates with the wheel. The transmitting wireless power supply component is used to transmit electrical energy provided by the power source to the receiving wireless power supply component, and the receiving wireless power supply component supplies power to the wheel-end electrical equipment according to the electrical energy transmitted by the transmitting wireless power supply component.

[0008] By placing the transmitting wireless power supply component on the non-rotating part of the vehicle and the receiving wireless power supply component on the rotating wheel end part that rotates with the wheel, a wireless power transmission path can be formed between the non-rotating part and the rotating wheel end part. This allows the receiving wireless power supply component to receive power as the wheel rotates and provide power to wheel end sensors, tire pressure monitoring devices, air pumps, communication devices, or other wheel end electrical devices.

[0009] In one possible implementation, the transmitting wireless power supply component includes a transmitting coil, and the receiving wireless power supply component includes a receiving coil.

By placing the transmitter wireless power supply assembly on different non-rotating components, the installation position of the transmitter wireless power supply assembly can be determined according to the vehicle structure and wheel-end space to adapt to different installation requirements.

[0015] In one possible implementation, the wheel-end electrical equipment includes an air pump, a receiver wireless power supply component, and the air pump, all housed within the same integrated structure. By integrating the receiver wireless power supply component and the air pump within the same structure, the receiver wireless power supply component can provide power to the air pump.

[0016] In one possible implementation, the air pump is connected to multiple air nozzles via air passages, with the nozzles spaced circumferentially along the integrated structure. Through the connection between the air pump, air passages, and multiple air nozzles, air can be delivered to corresponding locations, ensuring the tire's balance performance under dynamic conditions and preventing any impact on dynamic balance.

The method includes: controlling a power source to supply electrical energy to a transmitting wireless power supply component disposed on a non-rotating part of the vehicle; transmitting electrical energy to a receiving wireless power supply component disposed on a rotating part of the wheel end through the transmitting wireless power supply component; receiving electrical energy through the receiving wireless power supply component and supplying power to the wheel-end electrical equipment.

[0018] In one possible implementation, the transmitting wireless power supply component includes a transmitting coil, and the receiving wireless power supply component includes a receiving coil. At least one of the transmitting coil and the receiving coil is connected to a position adjustment mechanism. The method further includes controlling the position adjustment mechanism to adjust the spacing or relative position between the transmitting coil and the receiving coil.

[0019] In one possible implementation, the method further includes: adjusting the spacing or relative position between the transmitting coil and the receiving coil based on at least one of the receiving power, output voltage, and relative position information between the transmitting coil and the receiving coil of the receiving wireless power supply component.

[0020] In one possible implementation, the position adjustment mechanism includes a telescopic drive mechanism, and the method further includes controlling the telescopic drive mechanism to drive at least one of the transmitting coil and the receiving coil to extend or retract in a preset direction.

[0021] In one possible implementation, the method further includes: processing the electrical energy received by the wireless power supply component at the receiving end according to the type of wheel-end electrical equipment, and providing the processed electrical energy to the wheel-end electrical equipment.

[0022] In one possible implementation, the method further includes: adjusting the operating parameters of the transmitting wireless power supply component according to the power supply status of the receiving wireless power supply component, wherein the power supply status includes at least one of receiving power, output voltage, and energy storage status.

[0023] Thirdly, this application provides a wireless power supply device for wheel-end electrical equipment.

Detailed Implementation

[0030] The relevant technical solutions are described below with reference to the accompanying drawings. It should be understood that the following content is used to illustrate the implementation of this application and is not intended to limit the scope of protection. Where there is no conflict, technical features from different implementations can be combined with each other.

[0031] The following describes possible application scenarios for this application. This solution can be applied to passenger cars, commercial vehicles, engineering vehicles, low-speed vehicles, electric scooters, shared bicycles, mobile robots, automated guided vehicles, smart wheelchairs, or other devices equipped with wheel-end electrical devices. The following explanation uses a vehicle scenario as an example.

[0032] See Figure 1 As shown, Figure 1 This is a schematic diagram illustrating the arrangement of a transmitter wireless power supply component and a receiver wireless power supply component. The system may include a power supply 100, a transmitter wireless power supply component 200, a receiver wireless power supply component 300, and wheel-end electrical equipment 400. The power supply 100 provides power to the transmitter wireless power supply component 200.

[0033] The power source 100 can be a vehicle power battery, a storage battery, a low-voltage power source, a high-voltage power source, an energy storage device, or other components capable of providing electrical energy. The power source 100 can be directly installed in the vehicle or connected to the transmitter wireless power supply component 200 via a power management module. The power source 100 can also be a stand-alone energy storage component, for example, installed inside the vehicle body, near the wheel wells, or in other suitable installation locations.

[0034] At least one of the following can be installed between the power supply 100 and the transmitting wireless power supply component 200: a power management circuit, a power conversion circuit, a protection circuit, a switching circuit, a connection line, or a communication line. The power management circuit can control the on / off state, regulate the power, convert the voltage, or monitor the status of the power output from the power supply 100 according to the power supply requirements of the transmitting wireless power supply component 200.

[0035] The power conversion circuit can convert the electrical energy output from power supply 100 into electrical energy suitable for wireless power transmission. The protection circuit can handle overvoltage, overcurrent, overtemperature, short circuit, undervoltage, or other abnormal conditions. The connection lines can be wires, wire harnesses, connectors, flexible circuits, or other connection structures capable of transmitting electrical energy and signals.

[0036] The power supply 100 can adopt different power supply strategies according to the vehicle status. For example, when the vehicle is in the starting, driving, parking, charging, or diagnostic state, the power supply 100 can control the transmitter wireless power supply component 200 to start power supply, stop power supply, reduce output power, increase output power, or provide intermittent power supply. When the wheel-end electrical equipment 400 is in standby mode, its output power can be reduced; when the wheel-end electrical equipment 400 needs to perform detection, communication, inflation, or other tasks, it can start continuous power supply.

[0037] The transmitting wireless power supply component 200 is located on a non-rotating part of the vehicle. The transmitting wireless power supply component 200 can be located near the wheels in the suspension structure, braking structure, steering structure, body mounting structure, or on a specially designed mounting bracket. Its installation location can be determined based on the space at the vehicle's wheel ends, the position of the receiving wireless power supply component 300, coil size, protection requirements, heat dissipation conditions, and maintenance needs.

[0038] The transmitter wireless power supply assembly 200 can be mounted on a non-rotating component by screwing, snap-fitting, welding, bonding, embedding, or other fixing methods. When the transmitter wireless power supply assembly 200 is mounted on a mounting bracket, the mounting bracket can be connected to suspension components, braking components, steering components, or body components. The mounting bracket may also have a structure for adjusting the mounting position of the transmitter wireless power supply assembly 200.

[0039] The receiver wireless power supply component 300 is disposed on the wheel-end rotating component that rotates with the wheel. The receiver wireless power supply component 300 can be disposed in the center area of ​​the rim, the inner side of the rim, near the hub, on the tire support structure, or on the wheel-end mounting structure. The receiver wireless power supply component 300 can rotate together with the wheel-end rotating component and supply the received electrical energy to the wheel-end electrical device 400.

[0040] The receiver wireless power supply component 300 can be connected to the rotating part of the wheel end by means of screwing, snap-fitting, bonding, embedding, welding, press fitting, or integral molding. The receiver wireless power supply component 300 can also be housed within the same integrated structure as the wheel end electrical device 400. After the integrated structure is fixed to the rotating part of the wheel end, the receiver wireless power supply component 300 can rotate together with the integrated structure.

[0041] The wheel-end electrical device 400 can be mounted on the rotating part of the wheel end, or it can be connected to the receiving wireless power supply component 300 via wires, flexible connectors, connectors, or other power supply paths. For multiple wheel-end electrical devices 400, the receiving wireless power supply component 300 can supply power to each wheel-end electrical device 400 through multiple power supply branches. Different power supply branches can correspond to different output voltages, output currents, output power, or power supply sequences.

[0042] When the transmitting wireless power supply component 200 transmits electrical energy to the receiving wireless power supply component 300, the transmitting wireless power supply component 200 can output electrical energy through magnetic field coupling, electric field coupling, resonant coupling, or other non-contact energy transmission methods. After receiving the electrical energy, the receiving wireless power supply component 300 can directly supply power to the wheel-end electrical equipment 400, or it can process the electrical energy before supplying it.

[0043] When the rotating part of the wheel end rotates relative to the non-rotating part, the transmitting wireless power supply component 200 and the receiving wireless power supply component 300 can maintain wireless power transmission. In the scenario where the wheel is rotating, the receiving wireless power supply component 300 rotates with the rotating part of the wheel end, while the transmitting wireless power supply component 200 remains on the non-rotating part. This can reduce the wear and tear on the connecting components that may occur during power supply.

[0044] The transmitting wireless power supply component 200 and the receiving wireless power supply component 300 can be configured such that one component corresponds to one wheel-end power device 400, or one receiving wireless power supply component 300 can power multiple wheel-end power devices 400. Multiple wheel-end power devices 400 can share the power output from the receiving wireless power supply component 300, or they can receive power sequentially according to their working priority.

[0045] For example, the wheel-end sensor can operate in a low-power detection state most of the time, and the air pump can operate when the tire pressure is below a set range. The receiver wireless power supply component 300 can provide power to the wheel-end sensor or energy storage component when the air pump is not operating, and increase the power output to the corresponding power supply branch of the air pump when the air pump is operating.

[0046] When the power supply 100 is located on the vehicle's power battery side, it can supply power to the transmitter wireless power supply component 200 via the vehicle's low-voltage power distribution system, high-voltage power distribution system, or power conversion module. When the power supply 100 is set as an independent energy storage component, the independent energy storage component can replenish its power through the vehicle's charging interface, vehicle power management module, or other charging paths.

[0047] The power management module can obtain the power consumption request from the wheel-end electrical device 400, the output status of the receiving wireless power supply component 300, and the current status of the vehicle. After the wheel-end electrical device 400 submits a power consumption request, the power management module can control the power supply 100 to connect to the power supply path of the transmitting wireless power supply component 200. After the power consumption request ends or the set power supply duration is reached, the corresponding power supply path can be disconnected.

[0048] When the transmitter wireless power supply assembly 200 is located near the braking component, it can avoid the movement range and maintenance location of the braking component. When the transmitter wireless power supply assembly 200 is located near the suspension component, it can be fixed relative to the suspension component by means of a mounting bracket. When the transmitter wireless power supply assembly 200 is located near the steering component, an installation gap can be reserved according to the movement range of the steering component.

[0049] When the receiver wireless power supply assembly 300 is mounted on the rim or hub, it can be fixed using existing mounting holes, mounting surfaces, or specially designed mounting structures on the wheel-end rotating components. The housing of the receiver wireless power supply assembly 300 can be configured to fit the inner side of the rim or the outer shape of the hub, thereby reducing the space occupied by other wheel-end components.

[0050] A protective gap can be provided between the transmitting wireless power supply assembly 200 and the receiving wireless power supply assembly 300. This protective gap is used to prevent collisions between the two assemblies when the relative positions of the coils change. The protective gap can be related to the vehicle suspension's range of motion, wheel-end vibration range, or installation tolerances.

[0051] When there are a large number of wheel-end electrical devices 400, the output of the receiver wireless power supply component 300 can be connected to the wheel-end power distribution unit. The wheel-end power distribution unit can distribute the received power to the wheel-end sensors, communication equipment, air pumps, and actuators. The wheel-end power distribution unit can also control the power supply sequence according to the working priority of each device.

[0052] For example, wheel-end sensors and communication equipment can receive priority power when they need to collect status data or report data. When the air pump needs to work, the output power of the corresponding power supply branch of the air pump can be increased after the wheel-end sensor completes the current data collection cycle. For devices with limited simultaneous operation, a rotating or time-sharing power supply method can be adopted.

[0053] While the vehicle is parked, the power supply 100 can supply power to the receiving wireless power supply component 300 at longer power supply cycles to maintain the basic operation of wheel-end sensors, communication equipment, or energy storage components. While the vehicle is in motion, the power supply frequency can be increased or the continuous power supply time can be extended according to the real-time needs of the wheel-end electrical equipment 400.

[0054] The transmitter wireless power supply assembly 200 and the receiver wireless power supply assembly 300 can also be externally equipped with waterproof, dustproof, impact-resistant, or corrosion-resistant structures. These structures can be housings, sealing rings, coatings, protective covers, mounting plates, or other protective components. The specific protective structure can be determined based on the actual installation environment of the transmitter and receiver.

[0055] Power transfer between the transmitting wireless power supply component 200 and the receiving wireless power supply component 300 can occur when the vehicle is stationary or when the vehicle is in motion. For wheel-end electrical devices 400 that require higher power only when the vehicle is parked, higher power supply can be activated after the vehicle is parked. For wheel-end sensors or communication devices that need to operate continuously while the vehicle is in motion, the corresponding power supply can be maintained.

[0056] The power supply 100 can be connected to the wireless power supply component 200 at the transmitting end via a fuse, relay, electronic switch, or other switching device. The aforementioned switching device can cut off the power supply path when the vehicle is powered off, an abnormal state is detected, or the wheel-end electrical equipment 400 does not require power, or it can connect the power supply path when a wheel-end power replenishment request, a wheel-end electrical equipment operation request, or a maintenance request is received.

[0057] The installation position relationship between the transmitting wireless power supply component 200 and the receiving wireless power supply component 300 can be determined at the time of vehicle manufacture, or it can be redefined after replacing the wheels, wheel-end integrated structure, or related power supply components. When redefined, the transmitter position, receiver position, coil initial parameters, and position adjustment parameters can be updated.

[0058] For different vehicle models or wheel specifications, corresponding power supply component installation parameters can be set separately. The vehicle controller can select the corresponding installation parameters based on the vehicle model, wheel end structure identification, or stored configuration parameters. This allows the power supply component to adapt to different wheel end structures and wheel end spaces.

[0059] Without changing the power supply relationship described above, the specific installation positions, shapes, and connection methods of the power supply 100, the transmitting wireless power supply component 200, and the receiving wireless power supply component 300 can be set and adapted according to the vehicle structure, and are not limited here.

[0060] See Figure 2 As shown, Figure 2 This is a schematic diagram of magnetic field coupling for power transmission between a transmitting coil and a receiving coil. The transmitting wireless power supply component 200 may include a transmitting coil 210, and the receiving wireless power supply component 300 may include a receiving coil 310. Electrical energy can be transmitted between the transmitting coil 210 and the receiving coil 310 via magnetic field coupling.

[0061] The transmitting coil 210 and the receiving coil 310 can be planar coils, toroidal coils, helical coils, multi-turn coils, winding coils, or other coil structures suitable for wireless power transmission. The shape, size, number of turns, winding material, operating frequency, mounting direction, and core structure of the coils can be determined based on the wheel end mounting space, transmission distance, output power, and wheel end rotation state.

[0062] The transmitting coil 210 can receive electrical energy supplied by the power source 100 and form an alternating magnetic field for transferring energy to the receiving coil 310. When the receiving coil 310 is within the effective range of the alternating magnetic field, it can induce electrical energy. The transmitting coil 210 and the receiving coil 310 can form a magnetic induction coupling structure or a magnetic resonance coupling structure.

[0063] The transmitting coil 210 and the receiving coil 310 may have coil planes arranged opposite each other, or they may have central axes arranged opposite each other. When the coil installation space is limited, the shape of the transmitting coil 210 and the receiving coil 310 may be circular, ring-shaped, rectangular, arc-shaped, or other shapes depending on the actual installation location.

[0064] The transmitter wireless power supply assembly 200 may further include at least one of a drive circuit, a frequency control circuit, a power control circuit, an impedance matching circuit, a protection circuit, or a communication circuit. The drive circuit can provide alternating current to the transmitting coil 210. The frequency control circuit can adjust the operating frequency according to the coupling state of the coil. The power control circuit can adjust the transmission power according to the power supply requirements of the wheel-end electrical equipment 400.

[0065] Impedance matching circuitry can be used to adjust the output state of the transmitter wireless power supply component 200, ensuring that the transmitting coil 210 and receiving coil 310 maintain a suitable operating state for energy transfer. Communication circuitry can be used to transmit the operating state of the transmitter wireless power supply component 200, and also to receive control information from the receiver wireless power supply component 300, wheel-end controller, or vehicle controller.

[0066] The receiver wireless power supply assembly 300 may further include at least one of a rectifier circuit, a voltage regulator circuit, an energy storage circuit, a voltage conversion circuit, a power regulation circuit, a protection circuit, or a communication circuit. The rectifier circuit can convert the electrical energy output from the receiving coil 310 into DC electrical energy. The voltage regulator circuit can provide the wheel-end electrical equipment 400 with a voltage that meets the operating requirements.

[0067] The energy storage circuit may include a battery, supercapacitor, or other energy storage components for storing electrical energy obtained by the receiver wireless power supply component 300. The voltage conversion circuit can output electrical energy at different voltage levels according to the power supply requirements of different wheel-end electrical devices 400. The power regulation circuit can adjust the output state of each power supply branch when multiple wheel-end electrical devices 400 are working simultaneously.

[0068] The electrical energy obtained by the receiving wireless power supply component 300 can be used to directly power the wheel-end electrical device 400, or it can be stored in the energy storage circuit first. When the wheel-end electrical device 400 is in a low-power state, the received electrical energy can be used first to charge the energy storage circuit. When the wheel-end electrical device 400 requires higher power, the receiving wireless power supply component 300 can supply power directly, or it can be powered jointly by the receiving wireless power supply component 300 and the energy storage circuit.

[0069] The receiving coil 310 and the power processing circuit can be connected via wires, conductive sheets, conductive elastic elements, conductive rubber electrodes, connectors, or other conductive connectors. The conductive connectors can be located inside the integrated structure or within the mounting space formed by the rotating components at the wheel end. The arrangement of the conductive connectors can be determined based on the relative positions between the receiving coil 310 and the wheel-end electrical equipment 400.

[0070] The coil's operating parameters may include transmit power, operating frequency, output voltage, output current, receive power, resonant state, temperature, impedance parameters, or other parameters related to wireless power transmission. The transmitting wireless power supply component 200, the receiving wireless power supply component 300, or the vehicle controller can acquire the above parameters and adjust the power supply status according to changes in the parameters.

[0071] For example, when the output voltage of the receiver wireless power supply component 300 is lower than a set range, the output power of the transmitter wireless power supply component 200 can be increased. Once the output voltage of the receiver wireless power supply component 300 reaches the set range, it can maintain its current operating parameters or reduce its transmission power to meet current power requirements.

[0072] At least one of the following can be placed near the coil: a housing, an insulating device, a vibration damping device, or a sealing device. The housing can be used to secure the coil and circuitry. The insulating device can reduce unintended electrical connections between the coil and other conductive components. The vibration damping device can reduce the impact of wheel-end vibration on the coil's mounting condition. The sealing device is used to prevent liquids such as rainwater from affecting the coil's normal operation.

[0073] The coil's installation parameters can be pre-stored in the vehicle controller, the transmitter wireless power supply component 200, and the receiver wireless power supply component 300. These installation parameters may include the coil's initial position, initial spacing, target spacing, target angle, allowable offset range, adjustment stroke, or other parameters. After the vehicle starts, the corresponding installation parameters can be read as the basis for power supply control and position adjustment.

[0074] The center positions of the transmitting coil 210 and the receiving coil 310 can be set relative to each other in the initial installation state, or they can be offset to adapt to the preset structure. When the receiving coil 310 is located in the center area of ​​the rim, the transmitting coil 210 can be located on the side of the non-rotating component near the center of the hub. When the receiving coil 310 is located on the inner side of the rim, the transmitting coil 210 can be correspondingly located on a fixed structure near the inner side of the rim.

[0075] The transmitting coil 210 can be wound with a single layer or multiple layers. The receiving coil 310 can also be wound with a single layer or multiple layers. The number of windings and the winding arrangement can be determined based on the coil mounting area, allowable thickness, transmission power, and operating frequency.

[0076] A coil may include a magnetic core, a shielding layer, or an insulating layer. A magnetic core can be used to alter the magnetic field distribution near the coil. A shielding layer can be placed on the side of the coil away from another coil to reduce the influence of the magnetic field on adjacent components. An insulating layer can be placed between the coil windings and the housing, mounting bracket, or other conductive parts.

[0077] The transmission direction between the transmitting coil 210 and the receiving coil 310 can be understood as the main direction in which the transmitting coil 210 transfers energy to the receiving coil 310. The spacing between the coils can be determined along this transmission direction. The lateral offset can be determined in a direction perpendicular to this transmission direction.

[0078] The transmitting wireless power supply component 200 can drive the transmitting coil 210 with a first operating parameter during the initial power supply phase, and switch to a second operating parameter based on feedback information from the receiving wireless power supply component 300. The first operating parameter can correspond to the detected power supply status, and the second operating parameter can correspond to the normal operating status of the wheel-end electrical equipment 400.

[0079] The receiver wireless power supply component 300 can detect the AC voltage output by the receiving coil 310, the rectified DC voltage, the output current, the voltage or temperature of the energy storage component. The detection results can be used as a basis for adjusting the transmission power, adjusting the position, or controlling the power supply of the wheel-end electrical equipment 400.

[0080] When the receiver wireless power supply component 300 includes multiple output branches, each output branch can be connected to a wheel-end sensor, communication equipment, wheel-end controller, and air pump, respectively. Each output branch can be equipped with independent switching devices, current-limiting devices, voltage conversion devices, or protection devices to adapt to the operating requirements of different devices.

[0081] The energy storage component can be located inside the receiver wireless power supply assembly 300, or in other locations within the integrated structure. The energy storage component can provide backup power for wheel-end sensors, communication equipment, or air pumps. The capacity of the energy storage component can be determined based on the operating time, power requirements, and wireless power supply cycle of the wheel-end electrical equipment 400.

[0082] The transmitting wireless power supply component 200 and the receiving wireless power supply component 300 can exchange control information. For example, the receiving wireless power supply component 300 can send received power, output voltage, energy storage status, or fault status; the transmitting wireless power supply component 200 can send current transmit power, operating frequency, protection status, or position adjustment request.

[0083] During coil operation, the receiver wireless power supply component 300 can periodically record operating parameters. These recorded parameters can be used for vehicle maintenance, fault analysis, or control parameter updates. The operating parameters can be stored in the wheel-end controller, vehicle controller, or other storage devices.

[0084] When the transmitting wireless power supply component 200 is started, it can first detect the connection status, drive circuit status, and temperature status of the transmitting coil 210. The receiving wireless power supply component 300 can also detect the connection status, rectifier circuit status, and output status of the receiving coil 310. After the detection is successful, the transmitting wireless power supply component 200 can start transmitting power to the receiving wireless power supply component 300.

[0085] The receiver wireless power supply component 300 can input rectified electrical energy into the energy storage component, or it can directly input the energy into the wheel-end electrical device 400 via a voltage conversion circuit. When the operating voltage required by the wheel-end electrical device 400 is different from the voltage of the energy storage component, the voltage conversion circuit can perform boost or buck processing.

[0086] The transmitting coil 210 and the receiving coil 310 can operate at the same frequency, or they can operate at related frequencies under corresponding resonant structures. The specific value of the operating frequency can be determined according to the coil structure, power requirements, installation environment, and regulatory requirements. This application does not limit the specific operating frequency of the coil. When there are metal parts, housing parts, or other structures between the coils, the installation direction, shielding structure, or operating parameters of the coil can be adjusted according to the position of the structure.

[0087] See Figure 3 As shown, Figure 3 This is a schematic diagram of a position adjustment mechanism and a telescopic drive mechanism. The system may also include a position adjustment mechanism 500. The position adjustment mechanism 500 is connected to at least one of a transmitting coil 210 and a receiving coil 310. Figure 3 Taking the connection between the position adjustment mechanism 500 and the transmitting coil 210 as an example, the position adjustment mechanism 500 is used to adjust the distance or relative position between the transmitting coil 210 and the receiving coil 310.

[0088] The position adjustment mechanism 500 can be mounted on a non-rotating component or on a rotating component at the wheel end. The position adjustment mechanism 500 can adjust only the transmitting coil 210 or only the receiving coil 310. When the transmitting coil 210 is mounted on a non-rotating component, it can be moved by a drive structure mounted on the non-rotating component.

[0089] When the receiving coil 310 is mounted on the rotating part at the wheel end, it can also be moved by a drive structure mounted on the rotating part at the wheel end. The position adjustment mechanism 500 can also adjust both the transmitting coil 210 and the receiving coil 310 simultaneously. For example, one coil is used for initial position adjustment with a larger stroke, while the other coil is used for position compensation with a smaller stroke.

[0090] When the vehicle is parked, the initial positions of the transmitting coil 210 and the receiving coil 310 can be adjusted. During vehicle operation, minor compensations can be made based on coupling status, received power, or relative position. This allows for different handling methods to address initial coil installation errors and positional changes during vehicle operation.

[0091] The position adjustment mechanism 500 may include a telescopic drive mechanism. The telescopic drive mechanism is used to drive at least one of the transmitting coil 210 and the receiving coil 310 to extend or retract in a preset direction. The preset direction may be a direction toward the other coil, a direction away from the other coil, a radial direction at the wheel end, an axial direction, a circumferential direction, or other directions corresponding to the actual mounting structure.

[0092] Telescopic drive mechanisms can include motors, lead screws, gears, connecting rods, slide rails, elastic elements, hydraulic components, pneumatic components, electromagnetic drive components, shape memory drive components, or other parts capable of telescopic movement. Different drive methods can be selected based on installation space, drive stroke, response speed, power supply conditions, durability requirements, and control methods.

[0093] The position adjustment mechanism 500 can also cause at least one coil to translate, swing, rotate, or change its installation direction. When the position adjustment mechanism 500 includes a slide rail or guide structure, it can drive the coil to move in the lateral direction. When the position adjustment mechanism 500 includes a rotating structure, a swinging structure, or a flexible connection structure, it can change the coil plane, central axis, or installation direction.

[0094] The distance between the transmitting coil 210 and the receiving coil 310 can be used to determine the adjustment requirements of the position adjustment mechanism 500. The distance can be the distance between the two coils in the opposite direction, and can be determined based on preset installation parameters, distance sensor detection results, position sensor detection results, vehicle status information, or coil operating parameters.

[0095] When the spacing is greater than the set range, the position adjustment mechanism 500 can drive at least one coil to move towards the other coil; when the spacing is less than the set range, it can drive at least one coil to move away from the other coil. When the spacing is within the set range, the current position can be maintained, or the adjustment can be continued based on parameters such as received power and temperature.

[0096] In addition to the spacing, the lateral offset between the transmitting coil 210 and the receiving coil 310 can also be determined. The lateral offset can represent the positional difference between the two coils in a direction perpendicular to the coil's energy transmission direction. When the lateral offset exceeds a set range, the position adjustment mechanism 500 can control at least one coil to perform translation, oscillation, or other position adjustments.

[0097] The direction of lateral offset can be used to determine the direction of coil movement. For example, when the receiving coil 310 is offset towards the inside of the vehicle relative to the transmitting coil 210, the corresponding coil can be controlled to move towards the outside of the vehicle; when the receiving coil 310 is offset towards the outside of the vehicle relative to the transmitting coil 210, the corresponding coil can be controlled to move towards the inside of the vehicle. The actual direction of movement can be determined based on the installation direction of the coil.

[0098] The relative angle between the transmitting coil 210 and the receiving coil 310 can also be used for position adjustment. The relative angle can be the angle between the coil planes, central axes, or mounting directions of the two coils. When the relative angle does not meet the set conditions, the position adjustment mechanism 500 can drive at least one coil to rotate, swing, or change its mounting direction.

[0099] The position adjustment mechanism 500 can also determine whether to perform position adjustment based on the effective coupling range. The effective coupling range can be the spatial range within which the magnetic field output by the transmitting coil 210 can meet the energy receiving requirements of the receiving coil 310. If the receiving coil 310 is not within the effective coupling range, the position adjustment mechanism 500 can control at least one of the transmitting coil 210 and the receiving coil 310 to perform extension, retraction, translation, swinging, rotation, or other adjustment actions.

[0100] In one implementation, the coupling state, relative position information, or wireless power supply status between the transmitting coil 210 and the receiving coil 310 can be acquired. The coupling state can be represented by received power, output voltage, output current, transmission efficiency, reflection parameters, resonance state, coil spacing, or other parameters. The relative position information can be obtained from a position sensor, distance sensor, encoder, vehicle status information, or a preset model. The position sensor can be located in the position adjustment mechanism 500, the coil mounting structure, a non-rotating component, or a wheel-end rotating component. The vehicle status information may include vehicle speed, wheel speed, steering angle, acceleration, vibration information, or other vehicle operating information.

[0101] Based on the coupling state, relative position information, or wireless power supply status, the position adjustment mechanism 500 can be controlled to adjust the distance or relative position between the transmitting coil 210 and the receiving coil 310. For example, when the electrical energy received by the receiving wireless power supply component 300 is below a set range, the telescopic drive mechanism can be controlled to drive at least one coil to move towards the other coil.

[0102] When the electrical energy received by the receiving wireless power supply component 300 is within a set range, the movement of the position adjustment mechanism 500 can be stopped, and the current coil position can be maintained. When the electrical energy received by the receiving wireless power supply component 300 is continuously higher than the demand of the current wheel-end electrical equipment 400, the output power of the transmitting wireless power supply component 200 can also be reduced to reduce unnecessary energy output.

[0103] The position adjustment mechanism 500 may also have a position holding function. When the relative position between the transmitting coil 210 and the receiving coil 310 meets preset conditions, the position adjustment mechanism 500 can maintain the current extension length or the current position. Position holding can be achieved through mechanical limiting, locking structure, elastic preload, or other methods.

[0104] When the vehicle stops or wireless power supply ends, the position adjustment mechanism 500 can return the coil to its initial position or maintenance position. The maintenance position can be one that facilitates inspection, replacement, or avoidance of other wheel-end components. When the coil returns to its initial position, it can be controlled by a preset travel distance or by the detection results of the position sensor.

[0105] To avoid frequent operation of the position adjustment mechanism 500, adjustment thresholds, time thresholds, and adjustment intervals can be set. The position adjustment mechanism 500 will only continue to be controlled for adjustment if the coupling state continuously fails to meet the set conditions or if the relative position information continuously exceeds the set range. This reduces repetitive adjustments caused by short-term vibrations, detection errors, or instantaneous load changes.

[0106] The position adjustment mechanism 500 can also be equipped with a mechanical limiting structure. This mechanical limiting structure limits the maximum extension position, maximum retraction position, maximum translational position, or maximum swing angle of the coil. This allows the coil to move within the permissible installation space and reduces the possibility of the position adjustment mechanism 500 contacting other wheel end structures.

[0107] When the position detection result, communication, or drive mechanism malfunctions, the position adjustment mechanism 500 can be stopped from continuing to operate, and the current position can be maintained or the coil can be returned to a preset position. The transmitter wireless power supply component 200 can also reduce the output power or stop the power supply until the abnormal state disappears or a new control command is received.

[0108] The control objectives of the position adjustment mechanism 500 may include at least one of the following: keeping the coil spacing within a set range, keeping the lateral offset within a set range, keeping the relative angle within a set range, or ensuring that the received power meets set conditions. Different control objectives may be used individually or in combination according to preset priorities.

[0109] For example, if both the coil spacing and lateral offset do not meet the set range, the lateral position can be adjusted first by controlling the position adjustment mechanism 500, and then the coil spacing can be adjusted. If the relative angle deviates significantly from the set range, the coil installation direction can be adjusted first, and then spacing compensation can be performed according to the received power. The actual adjustment sequence can be determined based on the degree of freedom of the mechanism and the installation space.

[0110] The position adjustment mechanism 500 may include an encoder, limit switch, Hall sensor, photoelectric sensor, or other position detection component for detecting the current position of the coil. The position detection component may output the extension length, retraction length, translation distance, swing angle, or rotation angle. The controller can determine whether the position adjustment mechanism 500 has reached the target position based on the detection results.

[0111] When the position adjustment mechanism 500 uses a lead screw or rack and pinion drive, the motor's rotation can be used to determine the coil's movement. When the position adjustment mechanism 500 uses a connecting rod, slide rail, or elastic element, the coil position can be determined by a corresponding displacement sensor or limit structure. The specific form of different drive structures does not affect the position adjustment mechanism 500's ability to change the relative position of the coil.

[0112] The position adjustment mechanism 500 can be equipped with a preload structure. The preload structure can limit the free movement of the coil mount during vehicle vibrations and provide holding force after the coil reaches the target position. The preload structure can be a spring, elastic pad, elastic connector, locking element, or other component capable of providing preload force.

[0113] The position adjustment mechanism 500 may also be equipped with a buffer structure. The buffer structure may be located at the end of the stroke, between the coil mount and the bracket, or at other locations where contact may occur. The buffer structure can reduce the impact generated when the coil moves to the limit position.

[0114] The vehicle's steering action may alter the relative spatial relationship between non-rotating components and wheel-end rotating components. The position adjustment mechanism 500 can acquire steering angle information and select the corresponding target position or allowable offset range based on this information. Different adjustment parameters can be set for different steering directions.

[0115] When a vehicle travels over uneven road surfaces, the suspension components may move up and down. The position adjustment mechanism 500 can acquire information on the suspension status, vehicle acceleration, or wheel-end vibration, and when the vibration intensity is high, it can temporarily suspend large-stroke adjustments or use a smaller compensation stroke.

[0116] The adjustment action of the position adjustment mechanism 500 can adopt a closed-loop control method. After the controller issues an adjustment command, it can acquire the position detection result and the output status of the receiver wireless power supply component 300. When the position detection result reaches the target position and the output status meets the set conditions, the adjustment can be terminated.

[0117] The position adjustment mechanism 500 can also be controlled using an open-loop control method. In open-loop control, the drive mechanism's operation can be controlled according to preset installation parameters and preset stroke. Open-loop control is suitable for scenarios where the coil installation relationship is relatively fixed and frequent position compensation is not required.

[0118] The position adjustment mechanism 500 can perform a self-test before power supply begins. During the self-test, the drive mechanism can be controlled to move within a preset stroke, and the working status of the position detection component, limit structure, and drive component can be checked. If the self-test fails, wireless power supply can be stopped, or power supply can be applied to a preset fixed position without compromising safety.

[0119] The position adjustment mechanism 500 can share a controller with either the transmitter wireless power supply component 200 or the receiver wireless power supply component 300. Alternatively, the position adjustment mechanism 500 can have an independent controller. Different controllers can exchange position and power supply status via wired or wireless means.

[0120] When the relative positions of the transmitting coil 210 and the receiving coil 310 meet the set conditions but the received power still does not meet the requirements, the coil operating parameters, coil temperature, receiver load, or power processing circuit status can be checked. By combining the position status with the power status, invalid triggering actions caused by relying solely on position adjustment can be reduced.

[0121] When the relative position of the transmitting coil 210 and the receiving coil 310 exceeds the mechanical limit range, the position adjustment mechanism 500 can be stopped from moving in that direction.

[0122] The position adjustment mechanism 500 can be driven in either a continuous or stepped manner. In the continuous movement mode, the drive mechanism can move continuously to the target position within a preset stroke. In the stepped movement mode, the drive mechanism can move a preset distance each time, obtain the status of the receiving wireless power supply component 300, and then determine whether to continue moving.

[0123] When the position adjustment mechanism 500 performs graded movements, it can reduce the stroke of each action and detect the received power, output voltage, or coil position after each action. If the detection results indicate that the coupling state has improved, it can continue to move in the same direction; if the detection results indicate that the coupling state has not improved, it can stop moving or change the direction of movement.

[0124] The coil position adjustment can be set with a dead zone range. When the coil position is within the dead zone range, even if a small position change is detected, the position adjustment mechanism 500 will not be triggered. The dead zone range can be related to the vehicle vibration amplitude, the position sensor accuracy, and the range of received power fluctuations.

[0125] The position adjustment mechanism 500 can be set with a limit on the number of operations or a limit on the continuous working time. Once the limit is reached, adjustment can be paused and a status check performed. This limit can be used to prevent repeated adjustment actions from being performed under persistent abnormal conditions.

[0126] The target position of the position adjustment mechanism 500 can be represented by a preset position value, or indirectly determined by a preset received power, a preset output voltage, or a preset coupling state. When using a preset position value, the controller can move the coil to the corresponding position. When using an indirect determination method, the controller can detect the output state of the receiver wireless power supply component 300 during the adjustment process and stop the adjustment when the output state meets the conditions.

[0127] When a vehicle is fitted with different sizes of tires or rims, the initial spatial relationship between the coils may change. The corresponding target spacing, allowable lateral offset range, and position adjustment stroke can be redefined, or an initial search can be performed within a preset range by the position adjustment mechanism 500 to determine the coil position that meets the power supply conditions.

[0128] Wheel-end electrical equipment 400 may include at least one of a wheel-end sensor, a tire pressure monitoring device, an air pump, a wheel-end controller, a communication device, or an actuator. The wheel-end sensor may be used to acquire pressure, temperature, rotational speed, acceleration, vibration, position, or other wheel-end related parameters. The communication device may be used to transmit wheel-end data to a vehicle controller, vehicle infotainment system, gateway, or other devices.

[0129] When the wheel-end electrical equipment 400 includes a tire pressure monitoring device, the receiving wireless power supply component 300 can provide operating power to the tire pressure monitoring device. The tire pressure monitoring device can generate status information based on tire internal pressure, tire temperature, or other detection parameters, and transmit the status information via wired or wireless means. After receiving the status information, the vehicle controller can record faults, provide user prompts, or control other devices to perform corresponding operations.

[0130] When the wheel-end electrical equipment 400 includes communication equipment, the communication equipment can receive control commands sent by the vehicle controller, and can also send wheel-end status, wireless power supply status, air pump status, or fault information to the vehicle controller. The communication equipment can use wired communication, wireless communication, short-range communication, or other communication methods.

[0131] When the wheel-end electrical equipment 400 includes an actuator, the actuator can be a valve, locking device, regulating device, or other components requiring electrical power. The wheel-end controller can control the actuator's operation based on the vehicle status, the detection results of the wheel-end sensors, or instructions sent by the vehicle controller. The receiving wireless power supply component 300 can provide corresponding power according to the operating sequence of the actuator.

[0132] When the wheel-end electrical equipment 400 includes an air pump, the receiver wireless power supply component 300 can provide driving power to the air pump. The air pump can be used to supply gas to tires, pneumatic actuators, airbags, or other components requiring gas pressure. The start-up, shutdown, and operating duration of the air pump can be determined by the wheel-end controller, vehicle controller, or other control devices.

[0133] The receiver wireless power supply component 300 and the air pump can be housed within the same integrated structure. The integrated structure can be circular, ring-shaped, polygonal, housing, bracket, or any other structure capable of accommodating the receiver wireless power supply component 300 and the air pump. The integrated structure can be located on the rim, hub, tire support structure, or wheel end mounting structure, and rotates together with the rotating parts of the wheel end.

[0134] The integrated structure can be connected to the rotating components at the wheel end via screwing, snap-fitting, bonding, embedding, welding, vulcanization, or other fixing methods. Alternatively, the integrated structure can be integrally formed with the rotating components at the wheel end. The installation location of the integrated structure can be determined based on the wheel end space, air pump size, coil size, air path direction, heat dissipation conditions, protection requirements, and the mass distribution at the wheel end.

[0135] In one implementation, the air pump can be located in the central area of ​​the integrated structure, and the receiving coil 310 can be located around the air pump. The receiving coil 310 can be arranged around the air pump or on one side of the air pump. This arrangement can be adjusted according to the wheel end space, air pump size, coil size, and air path direction.

[0136] The air pump can be a miniature air pump, such as a miniature brushless DC air pump, or other air pumps suitable for wheel-end mounting. The air pump may include at least one of a drive component, a compression component, an air intake structure, an air outlet structure, and a control interface. The air pump can also be connected to an energy storage component to maintain the operation of some wheel-end electrical equipment 400 when the receiver wireless power supply component 300 is not continuously outputting power.

[0137] The integrated structure may also include at least one of a housing, a heat sink, a protective element, a vibration damping element, a seal, or a counterweight. The housing can protect the receiver wireless power supply assembly 300 and the air pump. For example, the vibration damping element can reduce the impact of wheel-end vibration on the internal components. The counterweight can be used to adjust the mass distribution of the integrated structure on the rotating parts at the wheel end.

[0138] See Figure 4 As shown, Figure 4 This is a schematic diagram of the air circuit connection between an air pump 600 and multiple air nozzles 620. The air pump 600 can be connected to multiple air nozzles 620 through air circuit 610. The multiple air nozzles 620 can be arranged at intervals along the circumference of the integrated structure. The number, spacing, and orientation of the air nozzles 620 can be determined according to the gas delivery requirements and the shape of the integrated structure.

[0139] The air pump 600 can be equipped with an independent drive circuit. The drive circuit can start, stop, or change the operating state of the air pump 600 according to the control commands output by the wheel end controller. The operating time of the air pump 600 can be determined according to tire pressure changes, air pump current, energy storage status, or preset time.

[0140] The air passage 610 may include air tubing, valves, distributors, connectors, seals, filters, pressure regulators, or other components for transmitting and controlling gas. Gas output from the air pump 600 can be distributed to multiple nozzles 620 via the air passage 610. Different nozzles 620 may correspond to the same tire space or to different gas usage locations.

[0141] The air passage 610 can be a flexible air tube, or it can be installed in an air passage formed inside the rim, hub, or integrated structure. When a flexible air tube is used, it can accommodate changes in the position between the air pump 600 and the valve 620. The valve 620 can communicate with the internal space of the tire, or it can communicate with the internal space of the tire via a valve core, connector, or other gas connection structure.

[0142] The valve 620 can be equipped with a sealing structure. The sealing structure can be located between the valve 620 and the air passage 610, or between the valve 620 and the tire or other air-using components. The sealing structure can be a sealing ring, sealant, gasket, or other components that reduce gas leakage.

[0143] The installation positions of the air pump 600, air passage 610, and air nozzle 620 can be adjusted without affecting the rotation of the wheel end. The air passage 610 can be arranged along the circumference, radial direction, or other preset path of the wheel rim. The air nozzle 620 can be set close to the position where gas needs to be delivered, or it can be set at a position spaced apart from the air pump 600 by extending the air passage 610.

[0144] The wheel-end sensor 640, tire pressure monitoring device, air pump 600, receiver wireless power supply component 300, and valve 620 can be arranged according to the mass distribution of the wheel end. For example, the wheel-end sensor and valve 620 can be positioned relative to each other or spaced apart circumferentially on the wheel end to reduce the impact of the integrated structure on the wheel's rotational balance. The actual positions of each component can be determined based on the rim structure, tire specifications, wheel end space, and assembly requirements.

[0145] The receiving coil 310 can be connected to the power processing circuit in the integrated structure. The power processing circuit can be connected to at least one of the energy storage component, the air pump 600, the wheel-end sensor, and the wheel-end controller. After receiving power, the receiving wireless power supply component 300 can output power to different components according to the current operating mode.

[0146] When the energy storage component's power level falls below a set range, the power supply 100 can be controlled to provide power to the transmitting wireless power supply component 200, and the transmitting wireless power supply component 200 can be controlled to transmit power to the receiving wireless power supply component 300. The position adjustment mechanism 500 can adjust the distance or relative position between the transmitting coil 210 and the receiving coil 310, so that the receiving wireless power supply component 300 can replenish power to the energy storage component.

[0147] When the tire pressure monitoring system detects that the tire pressure is below the set range, it can send a low-pressure message to the wheel-end controller or vehicle controller. The wheel-end controller or vehicle controller can then control the air pump 600 to start, causing the air pump 600 to deliver air into the tire through the air passage 610 and the air nozzle 620. When the tire pressure reaches the set range, the air pump operates for the set duration, or an abnormal condition is detected, the air pump 600 can be controlled to stop operating.

[0148] When the air pump 600 is operating, the receiver wireless power supply component 300 can directly supply power to the air pump 600, or the receiver wireless power supply component 300 and the energy storage component can supply power together. Wireless power supply and air pump operation can be carried out simultaneously, or they can be carried out according to a preset sequence. For example, the energy storage component can be charged first, and then the energy storage component can supply power to the air pump 600.

[0149] The wheel-end controller can determine the operating mode based on the status of the energy storage component, tire pressure, air pump, the power supply status of the receiver wireless power supply component 300, and the vehicle status. The operating mode may include at least one of the following: sensor power supply mode, energy storage component recharging mode, air pump supply mode, maintenance mode, and protection mode.

[0150] The wheel-end sensor can employ either continuous or periodic detection. When using periodic detection, the sensor can be activated at a preset acquisition time, and after detecting pressure, temperature, rotational speed, acceleration, or vibration parameters, it enters a low-power state. The receiver's wireless power supply component 300 can schedule corresponding power supply periods based on the acquisition cycle.

[0151] The wheel-end controller can be housed within the casing of the receiver wireless power supply component 300, or within the integrated structure containing the air pump 600. The wheel-end controller can receive detection results from the wheel-end sensors, status information from the tire pressure monitoring device, and control commands from the vehicle controller, and determine the operating status of the wheel-end electrical equipment 400 accordingly.

[0152] The wheel-end controller can generate a power replenishment request when the energy storage component's power level falls below a set range. This request can be sent to the vehicle controller via communication equipment or directly to the transmitting wireless power supply component 200. Upon receiving the power replenishment request, the transmitting wireless power supply component 200 can activate wireless power supply.

[0153] The vehicle controller can determine whether to allow the air pump 600 to operate based on tire pressure, vehicle speed, vehicle status, or user commands. For example, when the vehicle is parked, the air pump 600 can be allowed to perform inflation for a longer period of time; when the vehicle is moving, the operating time or output status of the air pump 600 can be limited according to preset conditions.

[0154] When the wheel-end sensor detects an abnormal pressure change, it can send the pressure change information to the wheel-end controller. The wheel-end controller can first confirm the detection result before controlling the air pump 600 to operate. The confirmation process can include multiple consecutive detections, judgment based on temperature parameters, or receiving confirmation commands from the vehicle controller.

[0155] The components within the integrated structure can be installed in a modular manner. At least one of the following: receiver wireless power supply component 300, air pump 600, energy storage component, wheel end controller, and communication equipment can be installed as an independent module within the integrated structure. During maintenance, the corresponding module can be inspected or replaced without altering the installation relationships of other modules.

[0156] During normal vehicle operation, the wheel-end sensors can acquire wheel-end parameters according to a preset cycle. The receiver wireless power supply component 300 can provide power to the wheel-end sensors, tire pressure monitoring equipment, or communication equipment, and can also charge the energy storage component. The wheel-end controller can control the output state of the receiver wireless power supply component 300 according to the sensor's working cycle and energy storage status.

[0157] When the vehicle is running, the installation parameters corresponding to the transmitter wireless power supply component 200, receiver wireless power supply component 300, and position adjustment mechanism 500 can be read. These installation parameters may include at least one of the following: initial coil position, preset spacing, adjustment stroke, allowable offset range, operating frequency range, and power range. After reading, initial position checks and power supply status checks can be performed.

[0158] When the vehicle is parked, the position adjustment mechanism 500 can be controlled to complete the initial coil alignment. After initial alignment, the transmitting wireless power supply component 200 can be controlled to perform power supply detection at a lower output power, and the output voltage, output current, received power, or other parameters of the receiving wireless power supply component 300 can be acquired. When the detection results meet the set conditions, normal power supply can be initiated.

[0159] When the vehicle is in motion, wheel rotation, vehicle body vibration, and road impacts may cause changes in the relative relationship between the transmitting coil 210 and the receiving coil 310. The position adjustment mechanism 500 can compensate based on the received power, relative position information, or vehicle status information. For short-term changes, the current position can be maintained; for continuous changes, corresponding adjustment actions can be performed.

[0160] The vehicle controller can acquire wheel speed, vehicle speed, steering angle, acceleration, or vibration information, and provide this information to the transmitting wireless power supply component 200, the receiving wireless power supply component 300, or the position adjustment mechanism 500. The position adjustment mechanism 500 can predict coil position changes based on vehicle status information, or use vehicle status information as the basis for determining adjustment thresholds, adjustment time, or adjustment stroke.

[0161] For example, when the vehicle is at low speed or parked, the position adjustment mechanism 500 can be allowed to perform a larger adjustment stroke; when the vehicle is traveling at high speed, the adjustment frequency and adjustment stroke of the position adjustment mechanism 500 can be limited. In this way, the position adjustment action can be adapted to the vehicle's operating state.

[0162] The transmitting wireless power supply component 200, the receiving wireless power supply component 300, and the position adjustment mechanism 500 can each be equipped with a communication interface. The communication interface can be used to send wireless power supply status, coil position status, air pump status, energy storage status, or fault information, and can also be used to receive power supply control commands, position adjustment commands, and air pump control commands.

[0163] When an abnormality is detected in the output of the wireless power supply component 300 at the receiving end, an abnormal coil temperature, the inability of the position adjustment mechanism 500 to move, the malfunction of the air pump 600, or a communication interruption, power transmission can be stopped, output power reduced, the position adjustment mechanism 500 stopped, the air pump 600 stopped, or a fault prompt can be sent. After the abnormal state disappears, the operation of the corresponding component can be restored according to preset conditions.

[0164] During vehicle maintenance or diagnostics, system status can be obtained through the vehicle diagnostic interface, communication equipment, or dedicated maintenance equipment. Maintenance equipment can send power supply test commands, position adjustment test commands, air pump test commands, or communication test commands to the system. The system can then execute the corresponding actions sequentially according to the test commands and output the test results.

[0165] For example, during maintenance, the position adjustment mechanism 500 can be controlled to extend and retract, and the detection results of the corresponding position sensors can be obtained to check the travel and limit status of the position adjustment mechanism 500. The transmitter wireless power supply component 200 can also be controlled to output detection power, and the output parameters of the receiver wireless power supply component 300 can be obtained to check the operating status of the coil and power processing circuit.

[0166] For air pump 600 and air circuit 610, air pump 600 can be controlled to operate for a preset time, and pressure parameters, air pump current, air pump operating time, or other parameters can be acquired. This process can be used to check the operating status of air pump 600, air circuit 610, air nozzle 620, and one-way valve. The test results can be stored in the vehicle controller, wheel end controller, or maintenance equipment.

[0167] The functions of each of the above components can be implemented by independent hardware, or by software, firmware, or a combination of hardware and software. The transmitter wireless power supply component 200, the receiver wireless power supply component 300, the position adjustment mechanism 500, and the wheel end controller can be independent components, or some of their functions can be integrated into the same control device.

[0168] Without conflict, the installation method, connection relationship, control method and working sequence of the power supply 100, the transmitting wireless power supply component 200, the receiving wireless power supply component 300, the wheel end electrical equipment 400 and the position adjustment mechanism 500 can be adjusted according to the vehicle structure and wheel end power supply requirements. The above content is used to illustrate the relevant technical solutions and is not intended to limit the scope of protection.

[0169] Before wireless power supply begins, it is possible to check whether the transmitting wireless power supply component 200, the receiving wireless power supply component 300, and the position adjustment mechanism 500 are in a working state. If the test results meet the requirements, the power supply process can be established. If the test results do not meet the requirements, the corresponding abnormal state can be recorded and awaited for the next test or maintenance.

[0170] During power supply, the received power, output voltage, energy storage status, coil position, and operating status of the wheel-end electrical equipment 400 can be acquired according to a preset cycle. Different parameters can use the same sampling cycle, or different sampling cycles can be used according to the rate of parameter change.

[0171] When the wheel-end electrical equipment 400 includes multiple devices, a working priority can be set for each device. For example, wheel-end sensors involved in tire condition detection can have a higher priority, and the air pump 600 can receive a larger power supply when the power supply capacity and vehicle condition conditions are met. The specific priority can be determined by the vehicle controller or the wheel-end controller.

[0172] The system can also enter a low-power state when the wheel-end power device 400 does not request power. In the low-power state, the transmitting wireless power supply component 200 can stop continuous transmission or send detection signals at longer intervals. When the receiving wireless power supply component 300 detects that power replenishment is needed or that the wheel-end power device 400 needs to operate, it can wake up the corresponding power supply process.

[0173] During vehicle diagnostics, the wireless power supply status can be associated with and saved with vehicle fault codes. For example, abnormal coil position, abnormal receiver output, abnormal position adjustment mechanism 500, abnormal air pump 600, or communication issues can each correspond to different diagnostic information. Maintenance personnel can then determine the components that need to be inspected based on the diagnostic information.

[0174] The system can also record the number of times the coil position is adjusted, the number of times the air pump 600 operates, the number of times the energy storage component is charged, or the number of times protection actions are activated. These records can be used to determine maintenance cycles, assess component condition, or adjust control strategies.

[0175] In the event of a communication interruption, the wheel-end controller can maintain basic detection and power supply functions according to a preset local strategy. For example, the wheel-end controller can maintain periodic detection by the wheel-end sensors, or it can stop the operation of non-essential equipment when the energy storage component's power is too low. After communication is restored, it can resend status information to the vehicle controller.

[0176] After replacing the wheel-end components, the transmitter wireless power supply assembly 200, or the receiver wireless power supply assembly 300 on the vehicle, the installation parameters can be rewritten or position calibration can be performed. Position calibration may include determining the initial position of the coil, the target spacing, the allowable offset range, or the travel range of the position adjustment mechanism.

[0177] Based on the same concept, this application also provides a wireless power supply method for wheel-end electrical equipment. See reference. Figure 5 As shown, Figure 5 This is a flowchart illustrating the steps of a wireless power supply method. This method can be executed by the transmitting wireless power supply component, the receiving wireless power supply component, or multiple components thereof as described in the above embodiments.

[0178] Step S501: Control the power supply to provide power to the wireless power supply assembly of the transmitter located on the non-rotating parts of the vehicle.

[0179] In this step, the power supply can be activated based on the operating status of the wheel-end electrical equipment. For example, when the wheel-end sensor needs to perform detection, the communication equipment needs to transmit data, the energy storage component needs to be recharged, or the air pump needs to operate, the power supply can be controlled to provide power to the wireless power supply component at the transmitter.

[0180] The power supply can continuously power the wireless power supply component at the transmitter, or it can power it according to a preset cycle. For wheel-end sensors, tire pressure monitoring devices, or communication devices in a low-power state, power can be activated according to the detection cycle or communication cycle. For wheel-end electrical equipment that requires higher power, such as air pumps, continuous power can be activated when it is determined that the air pump needs to work.

[0181] While controlling the power supply, vehicle status information can also be acquired. This information can include startup status, driving status, parking status, charging status, or diagnostic status. Different power supply durations, output power, or power supply cycles can be used depending on the vehicle's status. For example, when the vehicle is parked, energy storage components can be recharged, the air pump can be powered, or system diagnostics can be performed; when the vehicle is in motion, power can be maintained for wheel-end sensors and communication equipment.

[0182] Step S502: Power is transmitted from the transmitting wireless power supply component to the receiving wireless power supply component located on the rotating part at the wheel end.

[0183] After receiving electrical energy, the transmitting wireless power supply component converts the electrical energy into energy suitable for wireless transmission and transmits it to the receiving wireless power supply component. The receiving wireless power supply component rotates with the rotating part at the wheel end, while the transmitting wireless power supply component is located on the non-rotating part.

[0184] As one possible implementation, the transmitting wireless power supply component includes a transmitting coil, and the receiving wireless power supply component includes a receiving coil. The method further includes: transmitting the transmitting coil and the receiving coil transmitting electrical energy through magnetic field coupling.

[0185] The transmitting coil generates an alternating magnetic field after receiving electrical energy from a power source. When the receiving coil is within the range of the corresponding magnetic field, it can induce electrical energy. The transmitting and receiving coils can transmit electrical energy through magnetic induction coupling, magnetic resonance coupling, or other magnetic field coupling methods.

[0186] During transmission, the received power, output voltage, output current, energy storage status, or other power supply status parameters of the receiving wireless power supply component can be obtained. If the received power or output voltage does not reach the set range, the output power, operating frequency, or other operating parameters of the transmitting wireless power supply component can be adjusted. When the power supply status meets the operating requirements of the wheel-end electrical equipment, the current power supply status can be maintained.

[0187] Step S503: Receive electrical energy through the wireless power supply component at the receiving end and supply power to the wheel-end electrical equipment.

[0188] After receiving electrical energy, the wireless power supply component at the receiving end can rectify, stabilize, convert, store, or regulate the power before supplying it to the wheel-end electrical equipment. The wheel-end electrical equipment may include at least one of the following: wheel-end sensors, tire pressure monitoring devices, air pumps, wheel-end controllers, communication equipment, or actuators.

[0189] When the wheel-end electrical equipment is a wheel-end sensor or tire pressure monitoring device, the receiver wireless power supply component can provide the power required for detection and communication. When the wheel-end electrical equipment is an air pump, the receiver wireless power supply component can provide driving power to the air pump. The receiver wireless power supply component can also charge the energy storage component first, and then the energy storage component provides power when the wheel-end electrical equipment needs to work, or the receiver wireless power supply component and the energy storage component can be powered together.

[0190] In one implementation, the method further includes: processing the electrical energy received by the wireless power supply component at the receiving end according to the type of wheel-end electrical equipment, and providing the processed electrical energy to the wheel-end electrical equipment.

[0191] After receiving electrical energy, the wireless power supply component at the receiving end can rectify, stabilize, convert, store, or regulate the power before supplying it to the wheel-end electrical equipment. Different types of wheel-end electrical equipment may have different requirements for supply voltage, supply current, supply power, and supply duration. Therefore, the corresponding power processing method can be determined according to the type of wheel-end electrical equipment.

[0192] For example, when the wheel-end electrical equipment is a wheel-end sensor, tire pressure monitoring device, or communication device, the receiving wireless power supply component can convert the received electrical energy into corresponding low-voltage DC power and supply power to the wheel-end electrical equipment continuously or intermittently. When the wheel-end electrical equipment is an air pump or actuator, the received electrical energy can be stored, boosted, stabilized, or its power adjusted according to its power requirements during startup and operation to output electrical energy that meets the equipment's operational needs.

[0193] In one implementation, the wireless power supply component at the receiving end may include at least one of a rectifier circuit, a voltage regulator circuit, a voltage conversion circuit, an energy storage circuit, and a power regulation circuit. The rectifier circuit converts the electrical energy output from the receiving coil into DC power; the voltage regulator circuit keeps the output voltage within a set range; the voltage conversion circuit can boost or buck the voltage according to the power supply requirements of the wheel-end electrical equipment; the energy storage circuit provides buffer energy when the received power changes; and the power regulation circuit adjusts the power output to the wheel-end electrical equipment. By processing the received electrical energy according to the type of wheel-end electrical equipment, the same wireless power supply structure can be adapted to the power supply requirements of different wheel-end electrical equipment.

[0194] In one implementation, the method further includes adjusting the spacing and / or relative position between the transmitting coil and the receiving coil via a position adjustment mechanism.

[0195] During vehicle operation, the rotating parts at the wheel end may rotate, vibrate, shift, or undergo other relative movements relative to the non-rotating parts, and the distance, lateral offset, or relative angle between the transmitting coil and the receiving coil may change. The position adjustment mechanism can adjust the position of at least one coil based on the relative position information between the coils, the received power, the output voltage, or other power supply status parameters.

[0196] For example, if the power received by the wireless power supply component at the receiving end is below a set range, and it is determined that the distance between the transmitting coil and the receiving coil is greater than a set range, the position adjustment mechanism can be controlled to drive at least one coil to move towards the other coil. If the lateral offset exceeds a set range, at least one coil can be controlled to translate, swing, or perform other position adjustments. If the relative angle does not meet the set conditions, the installation direction of at least one coil can be adjusted.

[0197] After the position adjustment mechanism completes its adjustment, it can continue to acquire the power supply status of the receiver's wireless power supply component. If the power supply status meets the set conditions, the current position can be maintained; if the power supply status still does not meet the set conditions, the coil position can be adjusted again, or the operating parameters of the transmitter's wireless power supply component can be adjusted.

[0198] To reduce frequent actions caused by short-term vibrations or detection errors, adjustment thresholds, time thresholds, and adjustment intervals can be set. The position adjustment mechanism will only be activated when the power supply condition consistently fails to meet the set conditions or the relative position of the coil consistently exceeds the set range.

[0199] Using the above method, electrical energy can be transmitted between the non-rotating parts of the vehicle and the rotating parts at the wheel end, and power can be supplied according to the working requirements of the wheel-end electrical equipment. When the relative positions between the coils change, they can be adjusted by a position adjustment mechanism to keep the receiving wireless power supply component in a working state that meets the power supply requirements of the wheel-end electrical equipment.

[0200] In one implementation, the method further includes: adjusting the operating parameters of the transmitting wireless power supply component according to the power supply status of the receiving wireless power supply component, wherein the power supply status includes at least one of receiving power, output voltage, and energy storage status.

[0201] After the position adjustment mechanism completes the adjustment, it can continue to acquire the power supply status of the receiver's wireless power supply component. The power supply status can include at least one of the following: received power, output voltage, and energy storage status. Received power can indicate the amount of electrical energy received by the receiver's wireless power supply component; output voltage can indicate the voltage at which the receiver provides electrical energy to the wheel-end electrical equipment; and energy storage status can indicate the remaining charge, charging status, or energy storage voltage of the energy storage circuit.

[0202] When the power supply meets the set conditions, the current position and the current operating parameters of the transmitter's wireless power supply component can be maintained. If the power supply still does not meet the set conditions, the coil position can be readjusted, or the operating parameters of the transmitter's wireless power supply component can be adjusted. The operating parameters may include at least one of output power, operating frequency, and duty cycle.

[0203] For example, if the received power is lower than the set power, the output voltage is lower than the set voltage, or the energy storage level is lower than the set level, the output power of the transmitting wireless power supply component can be increased, the operating frequency adjusted, or the operating cycle extended. If the received power is higher than the set range, the output voltage is higher than the set range, or the energy storage level reaches the set upper limit, the output power can be reduced, the operating cycle shortened, or the power supply stopped. By adjusting the operating parameters of the transmitting wireless power supply component in conjunction with the power supply status of the receiving wireless power supply component, the power supply status can be controlled even after position adjustment, ensuring that the wheel-end electrical equipment receives the power required for operation.

[0204] Based on the above-described wireless power supply method, a wireless power supply device for wheel-end electrical equipment can also be provided. (See reference...) Figure 6 As shown, Figure 6 This is a schematic diagram of a possible structure for a wireless power supply device for wheel-end electrical equipment. The wireless power supply device may include a transmitting wireless power supply component and a receiving wireless power supply component. The transmitting wireless power supply component receives electrical energy from a power source and transmits electrical energy to the receiving wireless power supply component; the receiving wireless power supply component receives the electrical energy transmitted by the transmitting wireless power supply component and provides the received electrical energy to the wheel-end electrical equipment.

[0205] The transmitter wireless power supply component can be installed on a non-rotating part of the vehicle and connected to a power source. The power source can be a vehicle battery, accumulator, low-voltage power supply, high-voltage power supply, energy storage device, or other components capable of providing electrical energy. The transmitter wireless power supply component can directly receive electrical energy from the power source, or it can receive electrical energy via power management circuits, power conversion circuits, protection circuits, switching circuits, or connecting lines.

[0206] The transmitting wireless power supply component may include at least one of the following: a transmitting coil, a driving circuit, a frequency control circuit, a power control circuit, an impedance matching circuit, a protection circuit, or a communication circuit. The transmitting coil can receive electrical energy from a power source and form an alternating magnetic field for transferring energy to the receiving wireless power supply component. The driving circuit can provide alternating current to the transmitting coil; the frequency control circuit can adjust the operating frequency of the transmitting coil; and the power control circuit can adjust the transmission power according to the power supply requirements of the wheel-end electrical equipment.

[0207] The transmitting wireless power supply component can also be used to acquire power supply status information transmitted by the receiving wireless power supply component. This power supply status information may include received power, output voltage, output current, energy storage status, temperature status, fault status, or other information related to wireless power supply. The transmitting wireless power supply component can adjust its output power, operating frequency, duty cycle, or other operating parameters based on the power supply status information.

[0208] The wireless power supply component for the receiver can be installed on a rotating part of the wheel end that rotates with the wheel. The wireless power supply component for the receiver can include at least one of the following: a receiving coil, a rectifier circuit, a voltage regulator circuit, an energy storage circuit, a voltage conversion circuit, a power regulation circuit, a protection circuit, or a communication circuit. The receiving coil can receive electrical energy transmitted by the transmitting coil, the rectifier circuit can rectify the received electrical energy, and the voltage regulator circuit and voltage conversion circuit can output electrical energy that meets the operating requirements of the wheel-end electrical equipment.

[0209] The receiver-side wireless power supply component can directly supply the received electrical energy to the wheel-end electrical equipment, or it can first supply electrical energy to the energy storage component. The energy storage component can be a battery, supercapacitor, or other components capable of storing electrical energy. When the wheel-end electrical equipment requires higher power, the receiver-side wireless power supply component can directly supply power to the wheel-end electrical equipment, or it can be powered jointly by the receiver-side wireless power supply component and the energy storage component.

[0210] Wheel-end electrical equipment may include at least one of wheel-end sensors, tire pressure monitoring devices, air pumps, wheel-end controllers, communication devices, or actuators. When the wheel-end electrical equipment is a wheel-end sensor or a tire pressure monitoring device, the receiving wireless power supply component can provide the power required for detection and communication. When the wheel-end electrical equipment is an air pump, the receiving wireless power supply component can provide the driving power required for the air pump to operate.

[0211] In one implementation, the transmitting wireless power supply component can adjust the operating parameters of the transmitting coil based on the output voltage, received power, or energy storage status of the receiving wireless power supply component. The receiving wireless power supply component can control the output of power to the electrical equipment at each wheel end based on the received power status.

[0212] In one implementation, the wireless power supply component at the transmitting end or the wireless power supply component at the receiving end can adjust the spacing or relative position between the transmitting coil and the receiving coil based on the relative position information between the transmitting coil and the receiving coil, the received power, the output voltage, or other power supply status parameters.

[0213] When a wireless power supply device is implemented using a chip, chip circuit, or hardware logic, the wireless power supply components at the transmitting end and the wireless power supply components at the receiving end can be functional modules in integrated circuits, logic circuits, processors, or microprocessors.

[0214] The above component division is illustrative and represents only one logical functional division. In actual implementation, other division methods may be used. For example, the power control and frequency control functions in the transmitter wireless power supply component can be integrated into a transmission control module; the rectification, voltage regulation, and voltage conversion functions in the receiver wireless power supply component can be integrated into a power processing module; and the position adjustment control function can be set in the transmitter wireless power supply component, receiver wireless power supply component, wheel-end controller, or vehicle controller.

[0215] The aforementioned wireless power supply system may include a power source, a transmitting wireless power supply component, a receiving wireless power supply component, wheel-end electrical equipment, and the aforementioned wireless power supply device. The power source provides electrical energy to the transmitting wireless power supply component; the transmitting wireless power supply component is located on a non-rotating part; the receiving wireless power supply component is located on a rotating part of the wheel end; the wheel-end electrical equipment is connected to the receiving wireless power supply component. The wireless power supply device can be used to control the power transmission and output between the aforementioned components.

[0216] In one implementation, the wheel-end electrical equipment includes an air pump, and a wireless power supply component for the receiving end can be integrated with the air pump within the same structure. After the wireless power supply component for the receiving end provides power to the air pump, the air pump can deliver air to one or more air nozzles through the air passage. When the wheel-end sensor detects that the tire pressure is below a set range, the air pump can be started by the wheel-end controller or the vehicle controller.

[0217] See Figure 7 As shown, Figure 7 This is a schematic diagram of a possible structure of an electronic device. The electronic device 700 can be used to implement the functions of the aforementioned wireless power supply device or its module. The electronic device 700 can be a chip, a chip system, a controller, or other device with data processing capabilities. The chip system can be composed of chips or can include chips and other discrete components.

[0218] like Figure 7 As shown, the electronic device 700 may include at least one processor 710, which is coupled to a memory.

The processor 710 can determine the corresponding power supply control information, position adjustment information, or wheel-end electrical equipment control information based on the input power supply status information, coil position information, wheel end status information, or control commands.

[0221] The processor 710, memory 720, and communication interface 730 can be interconnected via a bus. The bus can be a Peripheral Component Interconnect (PCI) bus, an Extended Industry Standard Architecture (EISA) bus, or other types of buses. The bus can include an address bus, a data bus, a control bus, etc. For ease of representation, Figure 7 A single thick line can represent a bus, but this does not mean that there is only one bus or one type of bus.
