Description

TECHNICAL FIELD

[0001] The present application relates to the field of automobile wheel hub decoration, and in particular to a device, method and system for disassembling a wheel cover, and a vehicle. BACKGROUND

[0002] With the vigorous development of the new energy automobile industry, automobile design not only focuses on the innovation of power systems and the improvement of endurance, but also increasingly highlights the personalization and aesthetics of vehicle appearance. As an important visual component of automobile appearance, the design of wheel modeling has become one of the key links for vehicle manufacturers to shape product recognition and improve market competitiveness. Currently, in order to optimize the overall visual effect of the wheel and avoid the exposure of connecting components such as bolts / nuts to damage the design integrity, the industry generally adopts a wheel cover design scheme with a shielding structure, that is, the wheel bolts / nuts are completely or partially shielded by the wheel cover, so that the wheel appearance presents a more simple and integrated visual style.

[0003] However, the above-mentioned shielding type wheel cover design, while meeting the aesthetic needs of appearance, has brought significant inconvenience to the daily maintenance, repair and replacement operation of the wheel assembly. In use, the wheel cover needs to be disassembled first, and then the bolts / nuts are exposed, so that the disassembly and assembly of the wheel can be completed with the help of tools such as wrenches. When disassembling the wheel cover, a special disassembling hook is needed to separate the cover from the wheel body by applying an outward pulling force. This method has several defects: first, the disassembly process relies on a special disassembly tool, which limits the convenience of operation; second, manual disassembly requires a large pulling force, which not only requires labor, but also during the pulling process, if the force is uneven or too large, it is easy to cause the edge of the wheel cover to be damaged and deformed, affecting the service life of the component; third, due to factors such as the tightness of the cooperation between the cover and the wheel body, the wear of the cooperation surface after long-term use or the jamming of foreign matter, the hook end of the disassembling hook often slips after being stressed, or the cover and the wheel body are connected too tightly, which makes it difficult to disassemble, further reducing the reliability and efficiency of the disassembly operation, and causing great trouble to the actual maintenance work. SUMMARY

[0004] The embodiments of the present application provide a device, method, system and vehicle for disassembling a wheel cover, to solve the problem of poor operation convenience, damaged components and low disassembly reliability and efficiency when disassembling a wheel cover in related technologies, which leads to inconvenient maintenance and repair of the wheel assembly.

[0010] In some embodiments, the execution condition includes that the vehicle motion state is a static state and the maintenance mode state is a start maintenance mode.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] This application provides a device for removing wheel trim covers, which solves the problems of poor operation convenience, easily damaged parts, and low reliability and efficiency in the removal of wheel trim covers in related technologies, resulting in inconvenience in the maintenance and repair of wheel assemblies.

[0021] like Figure 1 As shown, a device for removing wheel cover trim includes: The rotary sealing device 1 is a hollow sealing structure, which is fixedly installed on the wheel hub bearing 2. The rotary sealing device 1 is installed on the wheel hub bearing 2 on the wheel side. One end is connected to the system distribution control valve through a pipeline to realize gas input, and the other end is connected to the pressure cover 7 of the second cavity on the back of the wheel decorative cover 4 after passing through the safety valve 10 to realize gas output. The wheel cover 4 is press-fitted with the inner wall of the central cavity of the wheel hub 3 by multiple radially distributed claws, forming a first-level clamping force. The brake disc 11 is mounted on the wheel hub bearing 2. The wheel cover 4, the wheel hub bearing 2, the brake disc 11, and the wheel hub 3 together form the first cavity 5. The wheel cover 4 has a boss 6 extending on the side facing the wheel hub bearing 2. The boss 6 is axially recessed on the side facing the wheel hub bearing 2 to form a groove. The pressure cover 7 is press-fitted to the inner wall of the boss 6 by multiple radially distributed claws, forming a secondary clamping force. The secondary clamping force is greater than the primary clamping force. Together with the boss 6 and the wheel decorative cover 4, it encloses the second cavity 8. The pneumatic pipeline 9 is connected at one end to the rotary sealing device 1 and at the other end to the second cavity 8; An electronic control unit, connected to the rotary sealing device 1, is used to control the air pressure in the first chamber 5 and the second chamber 8.

[0022] The embodiment of the application provides a device for disassembling a wheel decoration cover. When the wheel decoration cover needs to be disassembled, an electronic control unit controls compressed gas to continuously pressurize the first cavity 5 through the rotary sealing device 1 and the pneumatic pipeline 9: when the pressure increases to more than the secondary clamping force in the initial stage, the pressure cover 7 is separated from the boss 6; because the secondary clamping force is greater than the primary clamping force, the gas immediately enters the second cavity 8, and continuous pressurization makes the pressure in the second cavity 8 exceed the primary clamping force, thereby forming a rapid impact on the wheel decoration cover 4, so that the wheel decoration cover 4 is separated from the hub 3. Because the second cavity 8 is enclosed by the mounting surface of the hub 3 and the hub bearing 2 and the wheel decoration cover 4, there is a problem of insufficient sealing, and the scheme is that a first cavity 5 is arranged on the wheel decoration cover 4, and the secondary clamping force of the pressure cover 7 is greater than the primary clamping force of the wheel decoration cover 4, so that the pressure in the first cavity 5 is rapidly released to the second cavity 8, thereby forming an efficient impact on the wheel decoration cover 4. The structure does not need to be manually pried, and driving by gas pressure not only reduces the operation strength, but also effectively reduces the risk of scratching the hub and the wheel decoration cover.

[0023] Further, the pneumatic pipeline 9 is provided with a safety valve 10. The safety valve 10 is arranged between the rotary sealing device 1 and the pressure cover 7, and the safety valve 10 is controlled by a vehicle-mounted electronic control unit ECU to realize the communication of the first cavity 5 and the system pipeline. The electronic control unit (ECU) realizes real-time monitoring and dynamic regulation of the gas pressure in the first cavity 5 through a system distribution control valve. When the vehicle is in a stationary state and a maintenance mode is activated, the ECU instructs the control valve to open, gradually pressurizes to a preset threshold value, the pressure is transmitted to the second cavity 8 on the back of the wheel decoration cover 4 through the rotary sealing device 1, and the secondary clamping force is released; at the same time, the ECU continuously collects pressure sensor feedback data, and realizes overpressure protection and pressure stabilization in combination with the safety valve 10, so as to ensure that the gas pressure is instantaneously cut off when the inflation is completed, avoid sealing failure or component damage caused by pressure fluctuation, and thus ensure the accuracy, safety and reliability of the disassembly process.

[0024] Further, the secondary clamping force is set according to the volume ratio of the first cavity 5 to the second cavity 8 and the size of the primary clamping force.

[0025] In the embodiment, it is assumed that the primary clamping force of the wheel decoration cover 4 and the hub 3 is 100N, the volume ratio of the first cavity 5 to the second cavity 8 is 4:1, and the secondary clamping force of the pressure cover and the boss is 100N*4=400N. By setting two clamping forces and two cavities, the secondary clamping force of the pressure cover 7 is greater than the primary clamping force of the wheel decoration cover 4, so that the pressure in the first cavity 5 is rapidly released to the second cavity 8, thereby forming an efficient impact on the wheel decoration cover 4.

[0026] In some optional embodiments, in the adaptation scene of different vehicle models, the volume ratio of the first cavity 5 and the second cavity 8 can be dynamically adjusted. For example, for heavy-duty hub covers of high-end SUVs (the first-class joint force reaches 150N), the system can optimize the volume ratio from 4:1 to 5:1, so that the secondary joint force is automatically increased to 750N (150N x 5). The ECU automatically matches the volume ratio parameter through the pre-stored vehicle model database when the trigger instruction is triggered, and dynamically calculates the threshold based on the formula: secondary joint force = first-class joint force * volume of first cavity / volume of second cavity.

[0027] Further, the pneumatic pipeline 9 is sealingly connected with the rotary sealing device 1 and the pressure cover 7.

[0028] The embodiment of the application also provides a method for disassembling a wheel decorative cover, comprising the following steps: S1: obtaining vehicle information, the vehicle information comprising an instruction for automatically opening the wheel decorative cover, a vehicle motion state, and a maintenance mode state; In the embodiment, the vehicle control display screen of the vehicle-mounted human-machine interface (HMI) receives the "automatic opening of the wheel decorative cover" instruction triggered by the user, and at the same time, the electronic control unit (ECU) collects and comprehensively analyzes the vehicle motion state (including the real-time vehicle speed, the activation state of the braking system, the feedback of the ABS anti-lock system, and the steering signal, to ensure that the vehicle is in a completely static working condition and the parking brake is activated, and the maintenance mode state (activated by the maintenance diagnosis interface or the vehicle-mounted maintenance switch).

[0029] In an optional embodiment, to adapt to different user habits, the triggering mode of the automatic opening instruction can be flexibly extended. For example, the system supports voice instructions or mobile phone APP remote control, the voice instructions are converted into CAN signals through the vehicle-mounted voice recognition module, and the mobile phone APP remote control accesses the ECU through the vehicle-mounted gateway through the 5G network, both of which trigger the same vehicle state verification process as the main embodiment.

[0030] S2: determining whether the preset execution condition is met according to the vehicle motion state and the maintenance mode state; The ECU performs dynamic verification based on multi-source sensor data (such as a wheel speed sensor and CAN bus communication), and only when the vehicle motion state is static and the maintenance mode state is activated, the instruction for automatically opening the wheel decorative cover is confirmed to be valid and a control signal is output, so as to ensure that the pneumatic disassembly process is started under safe and compliant conditions, effectively avoiding the risk of sealing failure or mechanical damage caused by misoperation during driving, and significantly improving the reliability of the maintenance operation and the user interaction experience.

[0031] S3: If the execution condition is met, the electronic control unit causes the compressed gas to continuously pressurize the first cavity through the rotary seal device and the gas pipeline until the pressure cover is opened and the wheel cover is separated from the hub; if the execution condition is not met, the electronic control unit does not perform the pressurization operation.

[0032] When the execution condition is met, the system distribution control valve is opened, the gas is input through the rotary seal device 1, continuously delivered to the second cavity 8 through the pneumatic pipeline 9, and continuously pressurized. When the pressure reaches the secondary clamping force critical value (400N), the pressure cover 7 is quickly separated from the boss 6 under the action of instantaneous gas pressure, triggering the gas dynamic transfer of the first cavity 5 and the second cavity 8, and the gas rapidly fills the first cavity 5, forming an efficient impact on the wheel cover 4, thereby efficiently releasing the mechanical constraint of the wheel cover 4 on the hub 3, and achieving lossless separation.

[0033] Further, the execution condition includes: the vehicle motion state is a static state and the maintenance mode state is a start maintenance mode.

[0034] The electronic control unit verifies the execution condition through the vehicle-mounted multi-source sensor network and the diagnostic protocol: the static determination of the vehicle motion state depends on the wheel speed sensor (real-time monitoring of vehicle speed <5km / h), the parking brake state signal (confirming that the brake pedal has been activated), the ABS anti-lock system feedback and the steering signal (ensuring that the vehicle does not move laterally), forming a fourfold redundant verification; The maintenance mode state is activated through the OBD diagnostic interface or the special maintenance switch, and is not in the driving mode. The ECU uses a real-time data fusion algorithm to dynamically verify the above conditions, and only when all conditions are met at the same time will the disassembly process be triggered. The risk of misoperation during driving is completely eliminated, and the risk of vehicle loss of control or personal injury caused by accidental shedding of the wheel cover is avoided.

[0035] Further, after the wheel cover is separated from the hub, the electronic control unit controls the safety valve to close. The safety valve 10 on the pneumatic pipeline is a safety protection valve, and a control pressure threshold value of the safety valve 10 is set as 0.1 bar (a low pressure threshold value) and 3.5 bar (a high pressure threshold value), wherein the set value of 3.5 bar needs to be higher than a first level clamping force of the wheel cover 4 and the hub 3, and also needs to be higher than a second level clamping force of the pressure cover 7 and the boss 6. When the system detects that the pressure of the safety valve 10 is continuously lower than 0.1 bar or higher than 3.5 bar for 10 s, the safety valve 10 is automatically closed, so as to guarantee continuous output of the pressure and prevent damage to components caused by high pressure. After the wheel cover 4 is separated from the hub 3, the pressure in the first cavity 5 is rapidly released, the ECU closes the distribution control valve to terminate pressurization according to the pressure release state (that is, rapidly reduced to 0.1 bar or below), and the safety valve 10 is closed in linkage to complete airflow interruption, so as to ensure that the pressure is stably in a safe range and overpressure risk is avoided. If the execution condition is not met (for example, the vehicle is in a driving state or a maintenance mode is not activated), when the vehicle control display screen receives a user triggered “automatic opening of the wheel cover” instruction, the ECU does not perform any operation, that is, all the control valves are not opened, so as to effectively avoid potential safety risks and comprehensively guarantee the accuracy and safety of the dismounting process.

[0036] Further, the pressurization size is set according to the first level clamping force and the second level clamping force.

[0037] The electronic control unit (ECU) sets the pressurization size as a critical pressure threshold value of the second level clamping force through dynamic calculation, and the core logic is based on the formula: pressurization threshold value = second level clamping force × gas pressure conversion coefficient. Specifically, the system first obtains the first level clamping force (for example, 100 N) and a preset volume ratio (for example, 4:1), obtains the second level clamping force (100 N × 4 = 400 N) through calculation, and then converts the second level clamping force into a corresponding gas pressure threshold value (for example, 3.0 bar) in combination with the fluid dynamics characteristics (for example, cavity cross-sectional area, gas compression coefficient) of the rotary sealing device.

[0038] The ECU is provided with a vehicle model database, and can automatically match the first level clamping force parameters of different vehicle models (for example, the first level clamping force of a heavy SUV hub cover is 150 N) based on a VIN code, dynamically adjust the volume ratio (for example, 5:1) and recalculate the pressurization threshold value (750 N corresponds to 3.5 bar), so as to realize “one vehicle one parameter” adaptation. Without hardware modification, all series of vehicles from compact cars to heavy commercial vehicles can be covered, and the manufacturing cost is reduced by more than 30%.

[0039] According to the dismounting force of different wheel covers, different impact pressures can be adjusted and adapted. The dismounting of the wheel cover can be automatically, quickly and accurately controlled.

[0040] The embodiment of the application further provides a system for dismounting a wheel cover, comprising: The acquisition module is configured to acquire vehicle information, wherein the vehicle information comprises an instruction to automatically open a wheel trim cover, a vehicle motion state, and a maintenance mode state. The judgment module is configured to determine whether a preset execution condition is met according to the vehicle motion state and the maintenance mode. The control module is configured to, when the execution condition is met, cause the electronic control unit to continuously pressurize the compressed gas to the first cavity through the rotary sealing device and the gas pipeline until the pressure cover is opened and the wheel trim cover is separated from the hub, and then stop pressurizing; and when the execution condition is not met, the electronic control unit does not perform the pressurizing operation.

[0041] The dismounting wheel trim cover system provided by the embodiment of the application realizes a safe, efficient and intelligent automatic dismounting process through a modular architecture, and the core lies in the cooperative optimization of the acquisition module, the judgment module and the control module. The acquisition module receives a user instruction through a vehicle control display screen, and synchronously integrates vehicle-mounted multi-source sensor data (including real-time monitoring of a vehicle speed by a wheel speed sensor < 5 km / h, a parking brake state signal, ABS anti-lock system feedback and a steering signal), and simultaneously acquires a maintenance mode state through an OBD diagnostic interface; the judgment module performs redundant verification on the vehicle motion state and the maintenance mode based on a real-time data fusion algorithm built in an ECU, and only when the vehicle motion state is a static state and the maintenance mode state is a start maintenance mode, the execution condition is determined to be established, thereby avoiding the risk of false triggering; and the control module dynamically sets a pressurizing threshold (3.0 bar) according to a secondary clamping force calculation value (such as a primary clamping force 100N x a volume ratio 4:1 = 400N) when the condition is met, and when the pressure increases to more than the secondary clamping force, the pressure cover is separated from the boss, and since the secondary clamping force is greater than the primary clamping force, the gas immediately enters the second cavity, continues to pressurize to make the pressure in the second cavity exceed the primary clamping force, forms a rapid impact on the wheel trim cover 4, makes the wheel trim cover 4 separate from the hub, and simultaneously links the safety valve to instantaneously cut off the gas flow when the pressure suddenly drops, thereby avoiding overpressure damage. Since the second cavity is enclosed by the mounting surface of the hub and the hub bearing and the wheel trim cover, there is a problem of insufficient sealing, and the scheme sets the first cavity on the wheel trim cover, and uses the secondary clamping force of the pressure cover to be greater than the primary clamping force of the wheel trim cover, so that the pressure in the first cavity is rapidly released to the second cavity, thereby forming an efficient impact on the wheel trim cover. This system does not need an additional complex mechanical control mechanism, and through the two-stage gas chamber structure (the first cavity 5 and the second cavity 8), the wheel trim cover is realized to be separated from the hub without damage, and the safety valve 10 cuts off the gas flow within 0.1 seconds, thereby ensuring the safety and reliability of the whole operation. The inconvenience of manual dismounting in the prior art is avoided, time and labor are saved, and it is convenient and fast. According to the size of the dismounting force of different wheel trim covers, different impact pressures can be adjusted and matched. The dismounting of the wheel trim cover can be automatically and quickly and accurately controlled.

[0042] The embodiment of the application further provides a vehicle adopting the system for dismounting a wheel trim cover.

[0043] The vehicle provided by the embodiment of the application seamlessly embeds the function of disassembling the wheel decorative cover into the vehicle chassis architecture by deeply integrating the existing vehicle adaptive control system (such as the air spring system or the tire pressure adaptive system), without increasing the complexity of additional hardware. Specifically, the vehicle adds a device for disassembling the wheel decorative cover in the core air path of the air spring system: the existing compressed air source of the air spring system is used as a pneumatic power source, and is connected to the rotary sealing device 1 in the hub area through the customized pneumatic pipeline 9, to form a shared air path network with the existing system. This design discards the traditional independent air source or mechanical actuator, and only needs to load a special control algorithm in the ECU to realize the "one-key disassembly" function: when the user triggers the instruction through the vehicle control display screen, the ECU automatically disassembles the device for disassembling the wheel decorative cover based on the double verification of the vehicle stationary state and the maintenance mode state: the compressed air is delivered to the second cavity 8 through the rotary sealing device 1 and the pneumatic pipeline 9, the pressure is increased to exceed the secondary clamping force, the pressure cover 7 is separated from the boss 6, and since the secondary clamping force is greater than the primary clamping force, the gas enters the second cavity 8 immediately, continues to pressurize to make the pressure in the second cavity 8 exceed the primary clamping force, forms a rapid impact on the wheel decorative cover 4, and makes it separate from the hub 3. Since the second cavity is enclosed by the mounting surface of the hub and the hub bearing and the wheel decorative cover, there is a problem of insufficient sealing, the scheme sets the first cavity on the wheel decorative cover, and uses the secondary clamping force of the pressure cover to be greater than the primary clamping force of the wheel decorative cover, so that the pressure in the first cavity is rapidly released to the second cavity, forming an efficient impact on the wheel decorative cover. The vehicle does not need to add additional complex mechanical control mechanisms, and through the two-stage air chamber structure (the first cavity 5 and the second cavity 8), the wheel decorative cover is realized to be separated from the hub without damage, and the safety valve 10 cuts off the gas flow within 0.1 seconds, ensuring the safety and reliability of the whole operation. Avoid the inconvenience of manual disassembly of the prior art, save time and effort, and be convenient and fast. According to the size of the disassembly force of the different wheel covers, different impact pressures can be adjusted and adapted, and the disassembly of the wheel cover can be automatically and quickly and accurately controlled.

[0044] In some optional embodiments, the pneumatic driving + two-stage clamping force principle relied on by the wheel decoration cover disassembly device and method of the present application has the feasibility of cross-scenario migration application, and is not limited to the wheel decoration cover disassembly scenario. For example, in the battery pack maintenance scenario, the principle can be applied to the quick disassembly of the battery cover: the battery cover is configured with a gas chamber unit adapted to its structure, a two-stage clamping structure is designed between the gas chamber and the battery pack body, the first-stage clamping force is calculated and determined according to the volume ratio of the gas chamber and the second-stage clamping force (combined with the weight of the battery cover and the sealing requirement); after the vehicle control unit ECU determines that the vehicle is in a stationary state and the battery maintenance mode, the pneumatic pipeline is controlled to pressurize the gas chamber, and when the pressure reaches the preset value, the first-stage clamping structure is unlocked first, and then the gas fills the second-stage gas chamber to push the battery cover away, completing the quick disassembly and avoiding the problems of tool dependence, time-consuming operation and component damage in traditional manual disassembly of the battery cover.

[0045] In the vehicle window module replacement scenario, the core principle can also be reused: a corresponding gas chamber assembly and two-stage clamping structure are designed for the vehicle window module shell, the second-stage clamping force is set according to the connection strength requirement of the vehicle window module shell and the vehicle body frame, and the first-stage clamping force is calculated according to the volume ratio of the gas chamber; when the vehicle window module needs to be replaced, the disassembly instruction is triggered by the vehicle control system, the ECU first confirms that the vehicle is in a stationary state, then controls the distribution control valve to open, the gas enters the gas chamber through the rotary sealing device (adapted to the sealing requirement of the vehicle window module installation position), is pressurized to the threshold value to unlock the first-stage clamping, and is continuously pressurized to unlock the second-stage clamping, thereby conveniently pushing the vehicle window module shell away without the need for repeated prying of the surrounding components in the traditional disassembly process, improving the replacement efficiency and reducing the risk of component damage.

[0046] In summary, the beneficial effects of the present application are that the structure does not need manual prying operation, and the disassembly of the wheel decoration cover can be completed by pneumatic driving. On the one hand, this design greatly reduces the manual operation strength, and the worker does not need to use tools such as disassembly hooks for laborious pulling; on the other hand, compared with the hard contact between the manual disassembly and the hub and the decoration cover in the prior art, the smooth force of pneumatic driving can effectively reduce the risk of scratching the hub surface or damaging the wheel decoration cover during disassembly, and ensure the integrity of the component appearance.

[0047] At the same time, this scheme completely avoids the inconvenience of manual disassembly in the prior art - without the need for additional preparation of special disassembly tools, it also solves the problems of time-consuming and laborious manual operation, and even the problem of not being able to disassemble the decoration cover, achieving time-saving and labor-saving and convenience and speed in the disassembly process of the wheel decoration cover. In addition, in view of the disassembly force difference required by different specifications of wheel decoration covers, the system can realize automatic and quick disassembly of the wheel decoration cover by adjusting the impact pressure (such as calculating and setting the corresponding gas pressure threshold according to the decoration cover disassembly force requirement) in combination with the precise control of the vehicle control unit ECU, and can ensure the accuracy of the disassembly action, further improving the reliability and adaptability of the disassembly process.
