Description

Technical Field

[0001] This invention belongs to the field of wheel decorative cover technology, specifically relating to a deformable decorative cover assembly for vehicle wheel rims, its working method, and the vehicle. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] The driving range of new energy vehicles is one of the competitive indicators for automakers, and reducing the overall drag coefficient is an important way to improve driving range. Besides the overall vehicle design, the shape of the wheel rims also has a significant impact on the drag coefficient. Wheel rim covers are an effective way to reduce overall drag, but while reducing drag, they can also negatively affect the heat dissipation performance of the braking system.

[0004] In existing technologies, improving the heat dissipation efficiency of the braking system involves using fixed-perforation rims, but the perforations remain open, resulting in a consistently high drag coefficient. Conversely, while fixed-closed decorative covers can effectively reduce drag, the heat generated by the braking system is difficult to dissipate quickly during frequent braking or prolonged downhill driving, posing a safety hazard of reduced braking performance or even brake failure. Currently, designs are typically tailored to different market demands, or a trade-off is made between the two approaches. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a deformable decorative cover assembly for vehicle wheel rims, a working method, and a vehicle, solving the problem that existing vehicle wheel rim decorative covers cannot simultaneously meet the requirements of low wind resistance design and on-demand heat dissipation of the braking system.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, the present invention provides a deformable decorative cover assembly for a vehicle wheel rim, comprising a decorative cover, a wheel rim, and a heating control system; the decorative cover is composed of a first material layer and a second material layer, wherein the thermal deformation coefficient of the first material layer is less than that of the second material layer; a heating wire is embedded between the first material layer and the second material layer, and the heating wire is electrically connected to the heating control system; the decorative cover is installed on the wheel rim, and the outline of the decorative cover is adapted to the structure of the covered position of the wheel rim; the heating control system includes a temperature detection module for detecting the temperature of the braking system, a control module, and a heating module; the control module is electrically connected to the temperature detection module to receive temperature values ​​and send control commands according to the temperature values; the heating module is electrically connected to the control module and the heating wire, and controls the heating and stopping of the heating wire according to the control commands.

[0007] As a further implementation, the heating wire is disposed between the first material layer and the second material layer, and is distributed near the edge of the decorative cover.

[0008] As a further implementation, the decorative cover is installed on the wheel rim by a snap-fit ​​method.

[0009] As a further implementation, the edge of the decorative cover is beveled, which causes the edge of the decorative cover to fit against the rim.

[0010] As a further implementation, the first material layer is located on the side of the decorative cover away from the rim, and the second material layer is located on the side of the decorative cover closer to the rim.

[0011] Secondly, the present invention provides a method for operating a deformable decorative cover assembly for a vehicle wheel rim, comprising the following steps: The temperature detection module monitors the temperature of the braking system in real time and transmits the temperature value to the control module; The control module compares the temperature value with a preset temperature threshold. When the temperature value is higher than the temperature threshold, the control module sends a heating command to the heating module. The heating module controls the heating wire to heat up, and the heat is conducted to the decorative cover. The decorative cover deforms due to the heat, and the edges curl up to form an opening between the cover and the rim, thereby achieving air convection circulation to cool the braking system. When the temperature value is lower than or equal to the temperature threshold, the control module sends a stop heating command to the heating module, the heating module stops heating the heating wire, the temperature of the decorative cover decreases, the deformation is restored, the opening between the cover and the rim closes, and the low wind resistance state is restored.

[0012] As a further implementation, the preset temperature threshold includes a first temperature threshold and a second temperature threshold, wherein the first temperature threshold is lower than the second temperature threshold; when the temperature value is higher than the first temperature threshold and lower than the second temperature threshold, the heating module controls the heating wire to heat with a first heating power; when the temperature value is higher than or equal to the second temperature threshold, the heating module controls the heating wire to heat with a second heating power, wherein the second heating power is greater than the first heating power.

[0013] As a further implementation, the temperature detection module continuously collects the temperature value of the braking system at preset time intervals, and the control module dynamically adjusts the heating command according to the temperature change trend.

[0014] As a further implementation, the control module also presets an overheat protection threshold. When the temperature value detected by the temperature detection module exceeds the overheat protection threshold, the control module sends an emergency stop command to the heating module and triggers an alarm signal.

[0015] Thirdly, the present invention provides a vehicle including the aforementioned deformable decorative cover assembly for vehicle rims.

[0016] Compared with the prior art, the advantages and positive effects of this invention are: This invention fundamentally solves the contradiction between low wind resistance and braking heat dissipation. By designing the decorative cover as a double-layer structure composed of a first material layer and a second material layer with different thermal deformation coefficients, and embedding heating wires between the layers, a closed-loop control circuit is formed in conjunction with the heating control system. Under normal driving conditions, the decorative cover remains closed, its outline matching the structure of the covered rim, completely sealing the outer side of the rim and effectively reducing the wind resistance coefficient at the rim, thus improving the range of new energy vehicles. Under high-temperature conditions in the braking system, the temperature detection module detects that the temperature exceeds the limit, and the control module issues a heating command. The heating module drives the heating wire to heat up. Because the thermal deformation of the first material layer is less than that of the second material layer, the interlayer stress causes the edge of the decorative cover to lift up, automatically forming a heat dissipation opening between it and the rim, achieving air convection circulation and cooling. After the temperature returns to normal, heating stops, the decorative cover cools and returns to its original state, the opening closes, and it returns to a low-wind-resistance state, truly achieving a dynamic balance between low-wind-resistance driving and on-demand heat dissipation.

[0020] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0021] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. Example 1 This embodiment proposes a deformable decorative cover assembly for vehicle wheel rims, such as... Figures 1-3 As shown, the deformable decorative cover assembly for the vehicle rim mainly consists of three parts: the decorative cover 21, the rim 1, and the heating control system 214. These parts work together to achieve a temperature-responsive heat dissipation function for the braking system. The overall outline of the decorative cover 21 is adapted to the structure of the area of ​​the rim 1 to be covered. Specifically, the outer contour dimensions of the decorative cover 21 are consistent with the shape and size of the area to be covered on the outer side of the rim 1, ensuring that the decorative cover 21 completely and smoothly covers the rim 1 after installation, without any warping, gaps, or local protrusions, thus maintaining a good low-drag sealing effect under normal driving conditions.

[0022] like Figure 3 As shown, the decorative cover 21 is composed of a first material layer 211 and a second material layer 212. The coefficient of thermal deformation of the first material layer 211 is smaller than that of the second material layer 212, meaning that the linear expansion of the two materials when heated is significantly different, allowing the decorative cover 21 to automatically deform and open when heated. At room temperature, both layers are in their natural state, and the decorative cover 21 remains flat and closed, tightly fitting the rim 1. When the heating wire 213 is energized and heated, the thermal expansion of the first material layer 211 is significantly less than that of the second material layer 212, generating interlayer stress between the two layers. This causes the decorative cover 21 to bend towards the first material layer 211, resulting in a raised edge on the decorative cover 21, forming an opening 22 between it and the rim 1.

[0023] The heating control system 214 monitors the braking system temperature in real time and drives the heating wire 213 to operate. The heating control system 214 includes a temperature detection module, a control module, and a heating module. These modules work together via electrical connections to form a complete closed-loop control circuit. The temperature detection module is responsible for sensing the real-time temperature of the braking system; the control module is responsible for receiving temperature signals, executing judgment logic, and outputting control commands; and the heating module is responsible for driving the heating wire 213 to heat or stop heating according to the control commands.

[0024] During operation, the heating control system 214 continuously monitors the braking system temperature. When the braking system temperature is normal, the heating wire 213 is not energized, and the decorative cover 21 remains closed in a low-resistance state. When the braking system temperature rises above a preset threshold, the heating control system 214 activates heating, causing the decorative cover 21 to deform and open for heat dissipation. When the temperature returns to normal, heating stops, and the decorative cover 21 cools and returns to its original low-resistance state. The entire process requires no manual intervention, achieving fully automatic temperature-responsive heat dissipation control.

[0025] The heating wire 213 is embedded in the interface layer between the first material layer 211 and the second material layer 212, and is spatially concentrated near the edge of the decorative cover 21.

[0026] It is understandable that placing the heating wire 213 at the interface between the two material layers allows the heat generated to be conducted simultaneously in both directions—the first material layer 211 and the second material layer 212—improving heat utilization efficiency and reducing heat loss. Since the deformation opening effect of the decorative cover 21 mainly depends on the degree of warping at the edge, concentrating the heating wire 213 near the edge of the decorative cover 21 results in a faster and more complete temperature rise at the edge, a more significant warping deformation, a larger opening 22, and better heat dissipation.

[0027] By concentrating the heating wires 213 in the edge area, the edge area can be heated preferentially, generating sufficient deformation in a shorter time to quickly form an effective heat dissipation opening and shorten the heat dissipation response time. Specifically, the heating wires 213 can be evenly distributed circumferentially along the edge of the decorative cover 21, ensuring uniform heating and consistent deformation at each edge of the decorative cover 21, and avoiding irregular deformation or stress concentration caused by uneven local heating.

[0028] The decorative cover 21 is installed on the wheel rim 1 by a snap-fit ​​method. The snap-fit ​​installation method is a tool-free and easy-to-operate quick connection method. Specifically, the inner side of the decorative cover 21 is provided with several snap-fit ​​structures, and the corresponding position of the wheel rim 1 is provided with a slot or hole that cooperates with the snap-fit ​​structures.

[0029] During installation, align the decorative cover 21 with the rim 1 and apply appropriate pressure. The snap-fit ​​structure will elastically deform and embed into the slot or hole to lock it in place. For disassembly, use a special tool or manual operation to release the snap-fit ​​lock and remove the decorative cover 21.

[0030] Since the decorative cover 21 needs to warp and deform at the edges when heated, the snap-fit ​​installation method allows the edge position of the decorative cover 21 to shift relative to the rim 1 during deformation, without limiting the amount of deformation or damaging the connection structure due to excessive rigidity of the fixed connection. The snap-fit ​​structure can adapt to deformation when the edge of the decorative cover 21 warps and automatically returns to its original locked state after the decorative cover 21 cools and recovers, ensuring that the decorative cover 21 can reliably reset after each heat dissipation cycle.

[0031] The decorative cover 21 has a bevel at its edge, which allows the edge of the decorative cover 21 to fit snugly against the rim 1. The bevel is a sloping structure machined on the cross-section of the edge of the decorative cover 21, and its angle matches the shape of the corresponding contact surface of the rim 1.

[0032] The bevel structure improves the precision of the closed fit. The beveled surface forms a surface contact with the rim 1, resulting in a larger contact area and a tighter fit compared to a straight-edge structure without a bevel. This effectively eliminates the tiny gaps between the edge of the decorative cover 21 and the rim 1, improving airtightness in the closed state and reducing the drag coefficient. When the edge of the decorative cover 21 curls up due to heat, the beveled surface provides a guiding surface for the curling, causing the edge to curl up in a predetermined direction, forming a regular and uniform opening 22, avoiding irregular opening shapes caused by chaotic edge curling directions.

[0033] Compared to a straight edge structure, the beveled surface has lower cross-sectional stiffness. Under the same heating power, the beveled edge is more prone to warping deformation, which helps reduce the power consumption of the heating wire 213 and improve energy utilization efficiency. Fourth, it protects the surface of the rim 1. Compared to the line contact or point contact of a straight edge, the beveled surface has lower contact pressure per unit area, which can effectively protect the coating on the surface of the rim 1 and reduce wear on the surface of the rim 1 caused by repeated opening and closing of the decorative cover 21.

[0034] The first material layer 211 is located on the side of the decorative cover 21 away from the rim 1, and the second material layer 212 is the inner layer of the decorative cover 21.

[0035] When the heating wire 213 heats up, the thermal expansion of the first material layer 211 is less than that of the second material layer 212. Since the first material layer 211 is located on the outside, its expansion is constrained by the inner second material layer 212. The interlaminar shear stress generated between the two layers will drive the decorative cover 21 to bend outward, that is, the middle part of the decorative cover 21 bulges away from the rim 1, and the edge warps outward, forming an opening 22 between it and the rim 1. This deformation direction is perfectly in line with the heat dissipation requirements. The opening 22 formed by the warped edge is located at the joint edge between the decorative cover 21 and the rim 1, allowing external cold air to enter the inside of the rim 1 through the opening 22, exchange heat with the braking system, and then be discharged from the other opening, forming an effective convection circulation heat dissipation channel.

[0036] From the perspective of appearance and weather resistance, the first material layer 211 is located on the outer side and is directly exposed to the external environment. Therefore, in selecting materials, the first material layer 211, in addition to having a low coefficient of thermal deformation, should also possess good weather resistance, UV resistance, and surface hardness to meet the usage requirements of vehicle exterior parts. The second material layer 212 is located on the inner side and mainly undertakes the functions of structural support and a high coefficient of thermal deformation, with relatively lower requirements for appearance performance.

[0037] Example 2 This embodiment provides a method for operating a deformable decorative cover assembly for vehicle wheel rims, achieving a dynamic balance between heat dissipation and low wind resistance. It automatically opens the heat dissipation channel when the braking system is hot and automatically closes it when the temperature returns to normal, requiring no manual operation from the driver throughout the process. The method includes the following steps: Real-time temperature monitoring. The temperature monitoring module continuously monitors the temperature of the braking system in real time and transmits the collected temperature values ​​to the control module in the form of electrical signals. The temperature monitoring module is preferably installed in the high-temperature area near the brake caliper or brake disc to accurately reflect the actual operating temperature of the braking system.

[0038] Temperature Judgment and Command Transmission. The control module receives the temperature value transmitted by the temperature detection module and compares it with an internally preset temperature threshold in real time. When the temperature value is higher than the temperature threshold, the control module determines that the braking system is in a high-temperature state and needs to start heat dissipation, and then sends a heating command to the heating module; when the temperature value is lower than or equal to the temperature threshold, the control module determines that the braking system temperature has returned to normal and sends a stop heating command to the heating module.

[0039] Heating and heat dissipation. After receiving a heating command, the heating module supplies current to the heating wire 213. The heating wire 213 generates heat and transfers it to the first material layer 211 and the second material layer 212 through thermal conduction. Since the thermal deformation coefficient of the first material layer 211 is smaller than that of the second material layer 212, as the temperature rises, the expansion of the first material layer 211 gradually falls below that of the second material layer 212. The interlayer stress continuously increases, causing the edge of the drive decorative cover 21 to gradually warp up, forming an opening 22 between it and the wheel rim 1. External cold air enters the inner cavity of the wheel rim 1 through the opening 22, exchanges heat with the high-temperature braking system, absorbs heat, and is then discharged from the opposite side or other openings, forming a continuous air convection circulation and effectively cooling the braking system.

[0040] When the braking system temperature drops below the temperature threshold, the control module sends a stop heating command, and the heating module cuts off the power supply circuit to the heating wire 213, causing the heating wire 213 to stop generating heat. After losing its heat source, the temperature of the decorative cover 21 gradually decreases, the thermal expansion of the first material layer 211 and the second material layer 212 decreases synchronously, the interlayer stress is gradually released, the warping deformation of the edge of the decorative cover 21 gradually recovers, and the opening 22 between the decorative cover 21 and the rim 1 gradually shrinks until it is completely closed. The decorative cover 21 returns to the closed state, and the drag coefficient of the rim 1 returns to a low drag design state, effectively reducing vehicle driving energy consumption.

[0041] The control module has a preset first temperature threshold T1 and a second temperature threshold T2, with T1 being less than T2. ​​By setting these two temperature thresholds, the heat dissipation intensity of the braking system can be finely adjusted, avoiding excessive heat dissipation at slightly high temperatures that would lead to energy waste, and also avoiding insufficient heat dissipation at severely high temperatures that could cause safety hazards.

[0042] Specific control logic: When the braking system temperature is higher than T1 but lower than T2, the control module determines that the braking system is in a slightly high-temperature state and sends a first-level heating command to the heating module. The heating module controls the heating wire 213 to heat with a first heating power P1, causing the edge of the decorative cover 21 to slightly warp, forming a small opening 22 between it and the rim 1, achieving adequate heat dissipation. The first heating power P1 is relatively low, the heat output of the heating wire 213 is moderate, the temperature rise and deformation of the decorative cover 21 are both at a small level, the area of ​​the opening 22 is relatively limited, and the heat dissipation matches the slightly high-temperature state of the braking system.

[0043] When the braking system temperature is higher than or equal to T2, the control module determines that the braking system is in a severely overheated state and sends a second-level heating command to the heating module. The heating module controls the heating wire 213 to heat with a second heating power P2. P2 is greater than P1, so the heating wire 213 generates more heat, the decorative cover 21 heats up faster, deforms more, and the edge warps more significantly, forming a larger opening 22 between it and the wheel rim 1. This enhances heat dissipation, quickly reduces the braking system temperature, and prevents a decrease in braking performance.

[0044] In a specific implementation plan, T1 can be set to 150 degrees Celsius, and T2 can be set to 200 degrees Celsius. When the braking system temperature is between 150 and 200 degrees Celsius, heating is performed using the first heating power P1 (e.g., 30 watts) to create an appropriate amount of heat dissipation openings. When the braking system temperature reaches or exceeds 200 degrees Celsius, heating is performed using the second heating power P2 (e.g., 60 watts) to create larger heat dissipation openings, thereby enhancing heat dissipation. The above parameters are only examples and can be adjusted according to the specific vehicle model's braking system characteristics and heat dissipation requirements in actual applications.

[0045] The temperature detection module continuously collects the temperature values ​​of the braking system at preset time intervals and transmits these values ​​to the control module in real time. The preset time interval can be set according to actual needs, such as collecting data every 500 milliseconds, to ensure that the control system can respond promptly to rapid changes in the braking system temperature.

[0046] After receiving continuous temperature data, the control module not only compares the current temperature value with a threshold, but also analyzes and judges the temperature change trend, and dynamically adjusts the heating command accordingly. Specifically, the control module can determine the temperature change trend of the braking system by calculating the temperature change rate: when the temperature change rate is positive and large, it indicates that the braking system temperature is rising rapidly. The control module can issue a heating command in advance or increase the heating power to cause the decorative cover 21 to start deforming earlier, shorten the heat dissipation response time, and prevent temperature overshoot.

[0047] When the rate of temperature change is negative, it indicates that the braking system temperature is decreasing. The control module can appropriately reduce the heating power or issue a stop heating command in advance to avoid excessive deformation of the decorative cover 21 due to overheating, while also saving energy. When the rate of temperature change is close to zero, it indicates that the braking system temperature is stabilizing. The control module maintains the current heating power and keeps the decorative cover 21 in its current open state to achieve stable heat dissipation. By introducing dynamic analysis of temperature change trends, the control system has been upgraded from a simple threshold triggering mode to an intelligent control mode with predictive capabilities, significantly improving the heat dissipation response speed and control accuracy, enabling the decorative cover assembly to better adapt to complex and changing actual braking conditions.

[0048] In addition to the preset temperature threshold, the control module also presets an overheat protection threshold T3, which is higher than the second temperature threshold T2. The overheat protection threshold T3 is used to handle extreme situations where the braking system experiences abnormally high temperatures, such as braking system failure, prolonged continuous braking, or brake fluid failure leading to abnormal temperature increases. When the temperature detection module detects that the braking system temperature exceeds the overheat protection threshold T3, the control module immediately performs the following two operations: First, upon receiving an emergency stop command, the heating module immediately cuts off the power supply to the heating wire 213, ceasing the active heating of the decorative cover 21. At this time, although the braking system temperature is extremely high, the heating control system 214 actively stops heating based on the following safety considerations: the braking system temperature has exceeded the normal heat dissipation capacity range, and continuing to heat the decorative cover 21 will not effectively reduce the braking system temperature, but may instead cause irreversible deformation or material damage to the decorative cover 21 due to overheating; at the same time, after stopping heating, the heat from the braking system can still be dissipated naturally through the formed opening 22, maintaining a certain heat dissipation capacity.

[0049] Secondly, the control module sends an alarm to the driver via the vehicle bus or a separate alarm interface, such as illuminating the instrument panel warning light, issuing an audible alarm, or displaying a braking system overheat warning message on the in-vehicle display screen. This alerts the driver that the braking system is abnormally hot and requires immediate deceleration and stopping to take appropriate safety measures to prevent brake failure. The overheat protection threshold T3 should be set higher than the second temperature threshold T2, but not exceeding the maximum allowable operating temperature of the braking system. In one specific implementation, T3 can be set to 280 degrees Celsius, higher than T2 (200 degrees Celsius), triggering overheat protection when the braking system temperature exceeds 280 degrees Celsius to ensure driving safety.

[0050] Example 3 This embodiment provides a vehicle, including a body, chassis, drive system, braking system, and wheel system. The wheel system includes tires and rims 1. In this embodiment, each wheel rim 1 of the vehicle is equipped with the aforementioned deformable decorative cover assembly. The heating control system 214 is installed on the rim 1 of the corresponding wheel or at an appropriate position near the wheel.

[0051] In the integrated vehicle solution, the heating control system 214 for each wheel can operate independently. The temperature detection module of each wheel independently collects the temperature value of the corresponding braking system, and the control module independently judges and controls the working state of the corresponding heating module. This independent control scheme can respond to the braking system temperature of each wheel separately, adapting to the actual working conditions where the braking intensity of different wheels is uneven, such as the temperature difference caused by the different braking forces of the inner and outer wheels when braking in a curve.

[0052] In another integrated solution, the heating control system 214 for each wheel can be connected to the vehicle control unit via the vehicle bus, allowing the vehicle control unit to coordinate the heat dissipation control strategy for each wheel. The vehicle control unit can comprehensively consider various factors such as vehicle speed, braking intensity, ambient temperature, and gradient to optimize and schedule the heat dissipation control for each wheel, further improving the system's intelligence level and overall energy efficiency.

[0053] The deformable decorative cover assembly for vehicle rims of the present invention is applicable to various vehicles equipped with braking systems, including but not limited to passenger cars, commercial vehicles, and new energy vehicles. For new energy vehicles, since their regenerative braking systems also generate heat during energy recovery, the decorative cover assembly of the present invention can effectively cope with the high-temperature conditions of regenerative braking, and has broad application prospects.

[0054] By integrating the deformable decorative cover assembly of the vehicle rim into the vehicle, the vehicle maintains a low wind resistance design under normal driving conditions, effectively reducing driving energy consumption; when the braking system is hot, the heat dissipation channel is automatically opened to ensure the safe and reliable operation of the braking system; after heat dissipation is completed, it automatically resets to restore the low wind resistance state, realizing an intelligent dynamic balance between vehicle rim wind resistance control and braking heat dissipation function, taking into account both driving economy and braking safety.

[0055] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
