Description

Technical Field

[0001] This invention relates to the field of automotive technology, and more specifically to a device, method, and vehicle for removing wheel cover decorations. Background Technology

[0002] With the increasing popularity of automobiles and consumers' growing appreciation for aesthetics, wheel design styles are becoming increasingly homogenized. Wheels and wheel covers generally adopt an integrated design that conceals wheel bolts or nuts to enhance the vehicle's appearance.

[0003] However, this design causes significant problems in actual use: when users or repair shops need to disassemble or replace the wheel assembly, they must first remove the wheel cover to expose the internal bolts or nuts before proceeding with the subsequent operations.

[0004] Existing solutions typically involve setting a dedicated manual removal hole on the wheel cover, relying on tools such as a removal hook to be inserted into the hole and external force applied to forcibly pull out the cover. This method has several drawbacks: firstly, the operation requires additional specialized tools, increasing the complexity and cost of maintenance preparation; secondly, manual disassembly is inefficient, time-consuming, and labor-intensive. Summary of the Invention

[0005] This application provides a wheel cover removal device, removal method, and vehicle, which has the advantages of simple operation and efficient removal.

[0006] In a first aspect, embodiments of this application provide a wheel cover removal device, applied to a vehicle, the vehicle including a wheel hub body and a wheel cover detachably mounted on the wheel hub body, the wheel cover being connected to the wheel hub body via a snap-fit ​​structure, the wheel cover removal device comprising: Electromagnetic components are mounted on the hub body; A permanent magnet is disposed on the wheel decorative cover; and, The power supply unit is electrically connected to the electromagnetic component; The power supply unit is used to output a drive current to the electromagnetic component to provide an electromagnetic repulsion force axially away from the hub body to the permanent magnet component, thereby overcoming the locking force of the snap-fit ​​structure.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0021] In the traditional process of removing wheel covers, the locking force of the clip structure needs to be overcome by applying radial tension with external tools. However, the existing technology relies on the operation method of reserving manual removal holes and using removal hooks, which requires the intervention of special tools in the removal process. Moreover, poor contact during operation can easily cause damage to the cover or wheel hub. The essence of this problem is that mechanical removal cannot accurately control the direction and magnitude of the force, thus affecting the reliability of maintenance work and the integrity of the parts.

[0022] For example, in a vehicle repair scenario, when an operator attempts to apply radial tension using a disassembly hook through a pre-drilled hole in the trim cover, the hook may slip due to the gap between the hook and the trim cover's contact surface. Furthermore, this slippage causes the trim cover's edge to experience uneven stress, resulting in localized plastic deformation. Specifically, the latching structure remains locked in place because it is not fully unlocked, preventing the trim cover from being easily separated. This stuck state forces the repair operation to be interrupted, and the wheel hub's surface coating also develops scratches due to abnormal stress.

[0023] If the above problems are not solved, the locking force of the snap-fit ​​structure cannot be reliably overcome, which may cause the cover to be permanently stuck in the wheel hub body. This stuck state not only increases the difficulty of maintenance, but may also damage the coating on the surface of the wheel hub. Furthermore, the system maintenance cycle is forced to be extended, and the maintenance cost increases accordingly. As a preferred implementation method, this technical defect will directly affect the efficiency and quality of vehicle after-sales service.

[0024] To address the aforementioned problems, this invention proposes a wheel cover removal device, removal method, and vehicle, which has the advantages of simple operation and efficient removal.

[0025] Please refer to Figure 1 This invention proposes a disassembly device for a wheel cover 2, applicable to a vehicle. The vehicle includes a wheel hub body 1 and a wheel cover 2 detachably mounted on the wheel hub body 1. The wheel cover 2 and the wheel hub body 1 are connected by a snap-fit ​​structure. The disassembly device for the wheel cover 2 includes an electromagnetic component 3, a permanent magnet component 4, and a power supply unit. The electromagnetic component 3 is disposed on the wheel hub body 1. The permanent magnet component 4 is disposed on the wheel cover 2. The power supply unit is electrically connected to the electromagnetic component 3. The power supply unit is used to output a driving current to the electromagnetic component 3 to provide an electromagnetic repulsive force axially away from the wheel hub body 1 to the permanent magnet component 4, thereby overcoming the locking force of the snap-fit ​​structure.

[0026] In the technical solution of the present invention, through the coordinated action of the electromagnetic component 3, the permanent magnet component 4 and the power supply unit, when disassembly is required, it is only necessary to control the power supply unit to energize the electromagnetic component 3, so as to provide the permanent magnet component 4 with an axial electromagnetic repulsive force away from the hub body 1 to overcome the locking force of the buckle structure, thereby solving the problems of relying on additional tools and low operation efficiency in the prior art. It has the advantages of simple operation, efficient disassembly and reduced risk of component damage.

[0027] The electromagnetic component 3 is mounted on the wheel hub, and its mounting method can be varied. For example, the electromagnetic component 3 can be a simple coil, attached to the surface of the wheel hub by adhesive or mechanical fixation. As a preferred embodiment, the electromagnetic component 3 can be a ring-shaped electromagnet located at a specific position on the wheel hub. Furthermore, the electromagnetic component 3 can also be one or more independent electromagnet modules, distributed across different areas of the wheel hub.

[0028] The permanent magnet component 4 can be installed in various ways. For example, the permanent magnet component 4 can be one or more independent permanent magnets, fixed to the inner surface of the wheel cover 2 by adhesive or embedding. As another implementation, the permanent magnet component 4 can be a ring-shaped permanent magnet, installed in the structural groove of the wheel cover 2 by snap-fit ​​or press-fit. In addition, the permanent magnet component 4 can also be a layer of magnetic material, directly coated or laminated to a specific area of ​​the wheel cover 2.

[0029] The power supply unit outputs a drive current to the electromagnetic component 3, providing an axial electromagnetic repulsive force to the permanent magnet component 4, opposing the hub body 1, to overcome the locking force of the snap-fit ​​structure. The power supply unit can output the drive current in various ways. For example, it can continuously output a constant current, causing the electromagnetic component 3 to generate a constant magnetic field, thus producing a continuous repulsive force on the permanent magnet component 4. Alternatively, it can output a pulse current of a preset intensity, generating an instantaneous repulsive force for a short period. Furthermore, the power supply unit can be manually controlled to start or stop the generation of the repulsive force by operating a switch.

[0030] In some embodiments described above, a drive current is output to the electromagnetic component 3 via a power supply unit, thereby providing an electromagnetic repulsion force axially away from the hub body 1 to the permanent magnet component 4 to overcome the locking force of the snap-fit ​​structure. However, during implementation, if the relative positions between the electromagnetic component 3 and the permanent magnet component 4 are incorrect, the direction of the electromagnetic repulsion force may deviate from the expected direction, or the repulsion efficiency may be low, thus affecting the smooth removal of the wheel cover 2.

[0031] In this regard, this application further proposes that the electromagnetic component 3 and the permanent magnet component 4 are arranged coaxially.

[0032] "Coaxial arrangement" refers to the geometric axes of two or more components coinciding or parallel and lying on the same straight line. This arrangement aims to ensure that the magnetic field generated by the electromagnetic component 3 and the magnetic field of the permanent magnet component 4 can interact efficiently and accurately, thereby generating a stable electromagnetic repulsion force along the axial direction. Various methods can be used to achieve a coaxial arrangement. For example, precise machining and assembly can be used to align the central axis of the electromagnetic component 3 with the central axis of the permanent magnet component 4 during installation. Alternatively, guiding structures or positioning mechanisms can be designed, such as sleeve fits or boss-groove fits, to guide the electromagnetic component 3 and the permanent magnet component 4 to automatically align during installation, ensuring their axes coincide.

[0033] When the electromagnetic component 3 and the permanent magnet component 4 are coaxially arranged, the magnetic field generated by the drive current output by the power supply unit to the electromagnetic component 3 will have its magnetic field lines highly aligned with the magnetic field axis of the permanent magnet component 4. This alignment ensures that the electromagnetic repulsion force generated by the electromagnetic component 3 on the permanent magnet component 4 mainly acts axially, i.e., axially away from the wheel hub body 1. Through this axial alignment, the locking force of the snap-fit ​​structure can be overcome with minimal energy loss, achieving stable and reliable disassembly of the wheel cover 2. At the same time, this arrangement avoids lateral forces or torques caused by magnetic field misalignment, ensuring the smoothness of the disassembly process and reducing potential damage to the wheel cover 2 or the wheel hub body 1.

[0034] In a further embodiment, the permanent magnet 4 is located at the center of the wheel cover 2; the wheel hub body 1 is mounted to the vehicle via the wheel hub bearing 5, and the electromagnetic element 3 is arranged around the wheel hub bearing 5.

[0035] The permanent magnet 4 is positioned at the center of the wheel cover 2, meaning it is located at the geometric center of the wheel cover 2 in the radial direction. This arrangement helps ensure that the magnetic lines of force between the electromagnetic component 3 and the permanent magnet 4 are efficiently transmitted axially, thereby generating a stable axial repulsive force. The permanent magnet 4 can take various forms, such as ring-shaped, disc-shaped, or an array of multiple small permanent magnets. It can be securely installed on the inner surface or internal structure of the wheel cover 2 by means of bonding, embedding, snap-fitting, or bolting.

[0036] The electromagnetic component 3 is arranged around the wheel hub bearing 5 in a ring or near-ring shape on the wheel hub body 1. The wheel hub bearing 5 is typically located in the central area of ​​the wheel hub and has a fixed position and size. Arranging the electromagnetic component 3 around the wheel hub bearing 5 makes full use of the existing space around the wheel hub bearing 5, achieving compact integration of the electromagnetic component 3. The electromagnetic component 3 can be a single ring coil or composed of multiple segmented coils or electromagnet units arranged circumferentially. Its installation method can be fixed by a bracket, directly embedded into the structure of the wheel hub body 1, or installed in conjunction with the external structure of the wheel hub bearing 5.

[0037] The solution of this application achieves precise alignment and efficient coupling between the electromagnetic component 3 and the permanent magnet component 4 by placing the permanent magnet component 4 at the center of the wheel cover 2 and arranging the electromagnetic component 3 around the wheel hub bearing 5. When the power supply unit outputs a drive current to the electromagnetic component 3, the electromagnetic component 3 generates a magnetic field, which interacts with the magnetic field of the permanent magnet component 4 to generate an electromagnetic repulsion force axially away from the wheel hub body 1. Since the permanent magnet component 4 is located at the center of the wheel cover 2 and the electromagnetic component 3 is symmetrically arranged around the wheel hub bearing 5, this configuration ensures that the electromagnetic repulsion force can be concentrated on the central area of ​​the wheel cover 2 and uniformly transmitted along the axial direction, thereby effectively overcoming the locking force of the snap-fit ​​structure and achieving smooth disassembly of the wheel cover 2. This structural layout makes full use of the wheel hub bearing 5 as a central positioning reference, optimizing the installation position of the electromagnetic component 3, avoiding interference with other key components of the wheel hub body 1, and ensuring the accuracy of the direction of the electromagnetic repulsion force, thus improving the reliability and efficiency of disassembly.

[0038] Specifically, the electromagnetic component 3 includes a coil frame and an electromagnetic coil. The coil frame is arranged around the wheel hub bearing 5, and the electromagnetic coil is wound around the coil frame.

[0039] Through the above technical solution, the coil frame is arranged around the wheel hub bearing 5, and the electromagnetic coil is wound on the coil frame, effectively solving the problem of efficiently and stably integrating the electromagnetic component 3 within a limited space. The coil frame provides precise support and positioning for the electromagnetic coil, ensuring that the electromagnetic coil can be wound compactly and orderly, thereby optimizing the generation efficiency and directionality of the magnetic field. This structure allows the electromagnetic component 3 to form a more precise coaxial alignment with the permanent magnet component 4, enhancing the effect of electromagnetic repulsion and improving the reliability and efficiency of removing the wheel decorative cover 2. At the same time, the introduction of the coil frame also facilitates the manufacturing and installation of the electromagnetic coil, reduces production costs and assembly difficulty, and improves the structural stability and durability of the entire disassembly device.

[0040] It is understandable that in practical applications, the environment in which the wheel cover 2 is located is relatively harsh. If the permanent magnet 4 is directly exposed or improperly installed, it may be subject to corrosion or damage from external factors such as dust, moisture, and impact, thereby affecting its performance stability, service life, and even causing the disassembly function to fail.

[0041] In this regard, this application further proposes that the disassembly device for the wheel decorative cover 2 includes a support member 6, the support member 6 being used to enclose the wheel decorative cover 2 to form an installation cavity, and the permanent magnet 4 being installed in the installation cavity.

[0042] The solution of this application provides a protected installation environment for the permanent magnet 4 by setting up a support member 6, which together with the wheel cover 2 to form an installation cavity. The permanent magnet 4 is properly installed in this installation cavity, protecting it from the direct effects of external environmental factors (such as dust, moisture, road gravel impact, etc.) and vibrations and mechanical stresses generated during vehicle operation. This structural design ensures that the permanent magnet 4 can maintain its physical integrity and magnetic performance stability over a long period of time.

[0043] In one specific implementation, the support member 6 can be a ring-shaped plastic bracket, injection molded to precisely match the inner groove of the wheel cover 2. When the ring-shaped bracket is combined with the wheel cover 2, a closed or semi-closed mounting cavity is formed in the central area of ​​the wheel cover 2. The permanent magnet 4, such as a disc-shaped magnet, can be pre-fixed securely in the central hole of the ring-shaped bracket using adhesive or a snap-fit ​​structure. The inner wall of the wheel cover 2 can further cooperate with the support member 6 to form a complete protective cover, completely enclosing the permanent magnet 4 inside, thereby effectively isolating it from the external environment.

[0044] Similarly, the electromagnetic component 3 may also be subject to corrosion or damage from external factors such as dust, moisture, and impact. To protect the electromagnetic component 3, the electromagnetic coil and the like can be installed in a sealed housing for protection.

[0045] Based on the above-mentioned wheel cover 2 disassembly device, please refer to Figure 2 This application also proposes a method for removing the wheel decorative cover 2, including the following steps: S10: Obtain the command to remove wheel cover 2; S20: Control the power supply unit to output drive current to the electromagnetic component 3 to provide electromagnetic repulsion force axially away from the hub body 1 to the permanent magnet component 4, so as to overcome the locking force of the buckle structure and thereby remove the wheel decorative cover 2.

[0046] The "receive wheel cover 2 removal command" refers to the system receiving a signal from the user or a preset program to initiate the removal of the wheel cover 2. This command can come from various sources, such as physical buttons inside the vehicle, touchscreen interfaces, voice control systems, or wireless signals sent from external devices such as diagnostic tools or smartphone applications.

[0047] "Controlling the power supply unit to output drive current to the electromagnetic component 3" means that the system operates the power supply unit according to the received disassembly command, so that it provides the required electrical energy to the electromagnetic component 3. The control method may include, but is not limited to: adjusting parameters such as the magnitude, duration, and waveform of the current through a microcontroller or dedicated drive circuit; or directly connecting or disconnecting the power supply through a relay or power switch.

[0048] "To provide an electromagnetic repulsive force axially away from the wheel hub body 1 to the permanent magnet 4" means that the magnetic field generated by the electromagnetic component 3 after being energized interacts with the magnetic field of the permanent magnet 4, generating a force along the wheel axis that pushes the permanent magnet 4 and the wheel cover 2 away from the wheel hub body 1. "To overcome the locking force of the snap-fit ​​structure" means that the generated electromagnetic repulsive force must be large enough to counteract or exceed the locking force provided by the snap-fit ​​structure between the wheel cover 2 and the wheel hub body 1. Only when the repulsive force is greater than the locking force can the wheel cover 2 be separated from the wheel hub body 1.

[0049] In this application, when the system receives a clear instruction to remove the wheel cover 2, the vehicle's control system activates the power supply unit, causing it to output a preset drive current to the electromagnetic component 3 mounted on the wheel hub body 1. When the electromagnetic component 3 is energized, its generated magnetic field interacts with the magnetic field of the permanent magnet 4, thereby generating an electromagnetic repulsive force axially away from the wheel hub body 1. This repulsive force effectively overcomes the locking force of the snap-fit ​​structure between the wheel cover 2 and the wheel hub body 1, allowing the wheel cover 2 to separate axially from the wheel hub body 1, thus achieving its removal. This method combines the device's hardware capabilities with an intelligent operating procedure, ensuring the accuracy, controllability, and safety of the removal process, avoiding the inconvenience and potential damage that may result from traditional manual removal.

[0050] In one embodiment, the electromagnetic component 3 is adapted to a vehicle-mounted 12V DC power supply. It is non-magnetic when not energized, but during disassembly, a high-current pulse is applied, generating a strong axial magnetic field directed towards the outside of the wheel hub. The coil parameters are precisely matched to ensure an instantaneous current of 80–120A and a pulse width of 10–50ms, preventing the coil from overheating and burning out, while simultaneously generating a sufficiently strong magnetic field. The instantaneous electromagnetic repulsion force between the electromagnetic component 3 and the permanent magnet component 4 is set to 200–300N, greater than the pull-out force of the trim cover clips (180–250N).

[0051] In some of the embodiments described above in this application, a method for removing the wheel cover 2 by controlling the power supply unit to output a drive current to the electromagnetic component 3 is proposed. However, if the removal operation is performed indiscriminately during its implementation, the removal may be accidentally triggered when the vehicle is in an unsafe state, which may bring potential safety risks or unnecessary trouble.

[0052] In this regard, this application further proposes a step before the control power supply unit outputs drive current to the electromagnetic component 3, which also includes: Obtain vehicle status information; Determine whether the vehicle meets preset safety conditions, including whether the vehicle is stationary and in maintenance mode; If the conditions are met, then the step of the power supply unit outputting drive current to the electromagnetic component 3 is executed; If the conditions are not met, the output drive current is prohibited.

[0053] Acquiring vehicle status information refers to obtaining various parameter data when the vehicle is currently running or parked. This status information can be obtained through the vehicle's CAN bus system, such as data from the vehicle speed sensor, gear sensor, ignition switch status, etc.; alternatively, it can be obtained through the vehicle's diagnostic interface connected to external diagnostic equipment, or through the in-vehicle infotainment system or telematics unit.

[0054] Determining whether the vehicle meets preset safety conditions aims to ensure that the removal of the wheel cover 2 is carried out only in a safe and controllable environment, avoiding accidents. This determination can be achieved by the logic judgment module of the on-board controller, which compares the received vehicle status information with the preset safety conditions; alternatively, it can be achieved by a separate control module or software algorithm, which performs real-time analysis and logical judgment on the acquired vehicle status information.

[0055] The preset safety conditions include the vehicle being stationary and in maintenance mode. These refer to the specific operating states that the vehicle must meet before the wheel cover 2 removal operation is performed. The vehicle being stationary can be determined by monitoring the vehicle speed sensor signal; when the vehicle speed is zero and remains so for a period of time, the vehicle is considered stationary. Alternatively, it can be determined by combining gear information (such as P or N) and the handbrake status (engaged) to comprehensively assess whether the vehicle is completely stationary. Maintenance mode is a special mode that can be entered through the vehicle diagnostic system or through specific operations (such as key combinations or diagnostic tool activation), allowing maintenance operations to be performed. Alternatively, it can be activated through the vehicle's HMI (Human-Machine Interface) or a dedicated switch, indicating that the vehicle is in maintenance or repair mode.

[0056] The proposed solution, upon receiving a command to remove the wheel cover 2, does not immediately execute the removal operation. Instead, it first activates a safety check mechanism. This mechanism acquires real-time vehicle status information and compares it with preset safety conditions. Only when all preset safety conditions are met will the system allow the power supply unit to output drive current to the electromagnetic component 3, thereby generating electromagnetic repulsion to overcome the locking force of the latching structure and achieve the removal of the wheel cover 2. Conversely, if any safety condition is not met, the system will prohibit the output of drive current, effectively preventing removal operations under unsafe or unexpected conditions. This proactive safety judgment mechanism makes the removal operation more intelligent and safer, resolving potential safety hazards from directly executing removal commands and ensuring operational reliability.

[0057] It is understandable that in actual operation, due to individual differences, wear or environmental factors, the locking force of the buckle structure between the wheel cover 2 and the wheel hub body 1 may be affected by the driving current of a single fixed parameter. This may not guarantee the reliable disassembly of the wheel cover 2, or may cause unnecessary energy consumption or component burden due to excessive current output, thereby affecting the disassembly efficiency and the life of the device.

[0058] Please refer to Figure 3 In a further embodiment, step S20 includes: S21: Control the power supply unit to output drive current according to the initial drive parameters; S22: Monitor disassembly feedback signal; S23: If the wheel cover 2 is determined to have failed to separate successfully based on the disassembly feedback signal, the value of the drive parameter is increased according to the preset gradient, and the drive current is output again. S24: Repeat the above steps until the wheel cover 2 is successfully separated or the drive parameters reach the safe upper limit threshold.

[0059] The step of controlling the power supply unit to output drive current according to the initial drive parameters aims to initiate the disassembly process by providing an initial electromagnetic repulsion force to the electromagnetic component 3 through the power supply unit. The initial drive parameters can be preset current values, voltage values, or pulse widths, and their setting should be based on a preliminary estimate of the locking force of the snap-fit ​​structure or factory settings to provide sufficient initial disassembly force while ensuring safety. For example, it can be set to a current value that can overcome the minimum locking force, or a current value that can be stably output under normal operating conditions. The step of monitoring the disassembly feedback signal is used to obtain information about the disassembly status of the wheel cover 2. The disassembly feedback signal can take various forms, such as detecting the displacement, vibration, or sound changes of the wheel cover 2 through sensors, or indirectly judging by monitoring the electrical parameters (such as current, voltage, and inductance) of the electromagnetic component 3. When the initial drive force is insufficient to separate the wheel cover 2, the system will judge based on the feedback signal and gradually increase the drive parameters to enhance the electromagnetic repulsion force. For example, increasing the current value by 10% each time, or increasing a fixed voltage value after a certain time interval. Repeating the above steps until the wheel cover 2 is successfully removed or the drive parameters reach the safe upper limit threshold ensures the safety of the disassembly process.

[0060] The proposed solution achieves the removal of the wheel cover 2 in the following manner: First, the power supply unit outputs a drive current to the electromagnetic component 3 according to preset initial drive parameters, thereby providing the permanent magnet component 4 with an initial axial electromagnetic repulsion force away from the wheel hub body 1. Simultaneously with the drive current output, the system continuously monitors the removal feedback signal to assess whether the wheel cover 2 has been successfully separated. If the feedback signal indicates that the wheel cover 2 has not yet separated, it means that the current electromagnetic repulsion force is insufficient to overcome the locking force of the snap-fit ​​structure. At this point, the system gradually increases the value of the drive parameters according to a preset gradient and re-controls the power supply unit to output an enhanced drive current to provide a greater electromagnetic repulsion force. This cyclical process of monitoring, judging, adjusting, and re-outputting the drive current continues until the wheel cover 2 is successfully separated, or the drive parameters reach a preset safety upper limit threshold. This adaptive drive force adjustment mechanism allows the removal device to dynamically apply appropriate force according to the actual locking force, thereby ensuring a high success rate of removal while avoiding unnecessary excessive impact and energy consumption. This solution, combined with the aforementioned wheel cover 2 disassembly device and method, makes the disassembly process more intelligent and efficient, significantly improving the practicality and reliability of the device.

[0061] In some of the embodiments described above in this application, it is proposed to control the power supply unit to output a drive current to the electromagnetic component 3 and adjust the drive parameters according to the disassembly feedback signal to disassemble the wheel decorative cover 2. However, in the process of its implementation, how to accurately and in real time determine whether the wheel decorative cover 2 has been successfully separated is a key technical problem to ensure that the disassembly process is efficient, safe and avoids unnecessary energy loss.

[0062] Please refer to the following for details. Figure 4 This application further proposes that step S22 includes: S221: Collect electrical parameters of electromagnetic component 3 during the output drive current process, the electrical parameters including current waveform or inductance; S222: Analyze the variation characteristics of the electrical parameters; S223: If a preset abrupt change point is detected in the change feature, it is determined that the wheel decorative cover 2 has been displaced and successfully separated; wherein, the abrupt change point corresponds to the impedance change caused by the change in the relative position between the electromagnetic component 3 and the permanent magnet component 4.

[0063] The electrical parameters of the electromagnetic component 3 during the output drive current process are collected. These electrical parameters may include the current waveform, i.e., the curve of the current flowing through the electromagnetic component 3 changing over time, which reflects the dynamic response of the electromagnetic component 3; or the inductance. For example, the inductance can be monitored in real time by collecting the current waveform through a Hall sensor or a shunt resistor.

[0064] If a predetermined abrupt change point is detected in the aforementioned change characteristics, this refers to when the analysis results show that the electrical parameters undergo significant, nonlinear, and rapid changes beyond the normal range at a certain moment or within a certain interval, and this is identified as a critical node. This abrupt change point is determined in advance based on system characteristics and experimental data, representing a critical transition in the system state. Once such an abrupt change point is detected, the system determines that the wheel cover 2 has shifted and successfully separated. The physical basis for this determination is that the abrupt change point corresponds to the impedance change caused by the change in the relative position between the electromagnetic component 3 and the permanent magnet component 4. When the distance between the electromagnetic component 3 and the permanent magnet component 4 changes, the magnetic coupling strength between them changes accordingly, thereby affecting the equivalent inductance and resistance of the electromagnetic component 3, resulting in a measurable change in its overall impedance. This sudden change in impedance indicates that the wheel cover 2 has begun to detach from the wheel hub body 1.

[0065] This application provides an intelligent disassembly feedback mechanism by directly linking the magnetic coupling state between the electromagnetic component 3 and the permanent magnet component 4 with changes in the electrical parameters of the electromagnetic component 3. During the process of the power supply unit outputting drive current to the electromagnetic component 3 to generate electromagnetic repulsion, the system continuously monitors the electrical parameters of the electromagnetic component 3. When the electromagnetic repulsion overcomes the locking force of the snap-fit ​​structure, causing the wheel cover 2 to begin axially moving away from the wheel hub body 1, the relative distance between the electromagnetic component 3 and the permanent magnet component 4 changes. This change in relative position immediately alters the magnetic field distribution around the electromagnetic component 3, leading to a corresponding change in the impedance of the electromagnetic component 3 itself. By analyzing the changing characteristics of these electrical parameters (such as current waveform or inductance) in real time, the system can accurately capture the preset abrupt change points caused by the relative position change. Once such an abrupt change point is detected, it indicates that the wheel cover 2 has successfully displaced and separated from the wheel hub body 1. This real-time feedback mechanism based on physical effects allows the disassembly device to accurately determine the success or failure of the disassembly operation, thereby avoiding blindly increasing the drive current or excessively applying repulsion force, ensuring precise control and efficient execution of the disassembly process.

[0066] The present invention also proposes a vehicle including a wheel cover 2 removal device. The specific structure of the wheel cover 2 removal device is as described in the above embodiments. Since the vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0067] The solution proposed in this application integrates the removal device for the aforementioned wheel cover 2 directly into the vehicle, making it an inherent functional component of the vehicle. Specifically, the vehicle's power system provides a stable power supply to the power supply unit of the removal device, and the vehicle's control system receives removal commands from the user or vehicle diagnostic system and coordinates the power supply unit to output drive current to the electromagnetic component 3. When the wheel cover 2 needs to be removed, the vehicle's control system activates the removal device, generating electromagnetic repulsion between the electromagnetic component 3 and the permanent magnet component 4, thereby overcoming the locking force of the snap-fit ​​structure and achieving automatic separation of the wheel cover 2. This integration method makes the removal of the wheel cover 2 more convenient and efficient, requiring no additional tools or manual intervention, and is particularly suitable for scenarios such as vehicle repair or tire replacement. By making the removal device part of the vehicle, the removal process can be automated and intelligently managed, for example, by combining vehicle status information for safety control to avoid misoperation.

[0068] By integrating the wheel cover 2 removal device directly into the vehicle using the above technical solution, the problems of low integration and inconvenient operation associated with the removal device as a separate component in practical applications are solved. This integration makes the removal function an inherent attribute of the vehicle, greatly improving the convenience and automation of wheel cover 2 removal. Users do not need to find or carry special tools; they can complete the removal operation through the vehicle's own control system, significantly saving time and effort, especially during emergency repairs or routine maintenance. Furthermore, the vehicle system can intelligently manage and control the removal process, such as prohibiting removal while the vehicle is in motion, thereby effectively avoiding potential safety risks and misoperation, and improving the overall safety of the vehicle and the user experience.
