[0002] The wheel arch is one of the important accessories of a vehicle, which is used to block mud, sewage, ice and snow splashed during vehicle driving; when the vehicle is driving on a road covered with snow or ice, the wheels contact the road surface and crush the ice and snow, and part of the ice and snow will be carried up by the rotation of the tires and thrown to the side of the wheel arch close to the wheels under the action of inertia. When the ambient temperature is relatively low, the ice and snow attached to the inner side of the wheel arch are easy to freeze, and over time, a layer of ice and snow that is difficult to remove will be formed on the inner side of the wheel arch, thereby increasing the risk of corrosion and damage to the wheel arch structure. Summary of the Utility Model

[0027] To make the objectives, technical solutions, and advantages of this application more clear and understandable, the following further elaborates on this application in detail in conjunction with specific embodiments and with reference to the accompanying drawings.

[0028] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of this application should have the ordinary meanings understood by those with ordinary skills in the field to which this application belongs. The "first", "second", and similar terms used in the embodiments of this application do not indicate any order, quantity, or importance, but are only used to distinguish different components. Words such as "including" or "comprising" mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects. Words such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Upper", "lower", "left", "right", etc. are only used to represent relative position relationships. When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0029] In cold and snowy environments, the road surface is usually covered with ice or snow. When a vehicle travels on a road covered with ice or snow, the wheels will crush the ice and snow and drive the ice and snow away from the road surface; affected by inertia, the ice and snow carried by the wheels will be thrown towards the wheel arch, accumulating inside the wheel arch; as the vehicle travels in a low-temperature environment and snowy road conditions for a long time, the ice and snow inside the wheel arch will gradually increase and it is difficult to fall off from the inside of the wheel arch, thus gradually forming an ice and snow accumulation layer. Since the ice and snow frozen inside the wheel arch is relatively thick, it is difficult to clean, and scratches are easily left on the inside of the wheel arch during the cleaning process. In severe cases, it may even cause damage to the wheel arch, bringing unnecessary trouble to the user.

[0030] In addition, the ice and snow accumulation layer accumulated inside the wheel arch will also have other adverse effects on the vehicle; for example, since most of the ice and snow accumulation layer attached to the inside of the wheel arch comes from the road surface, the formed ice and snow accumulation layer may cause corrosion and damage to the wheel arch structure; secondly, when the thickness of the ice and snow accumulation layer is too thick, it may rub against the surface of the vehicle tire, increasing the friction of the tire; in addition, the presence of snow inside the wheel arch will also interfere with the vehicle's suspension system and steering mechanism, affecting the flexibility of the wheel movement during steering, increasing the difficulty of controlling the vehicle, and affecting driving safety.

[0031] In view of this, the present application provides a wheel arch cleaning device, including: a wheel arch body 100, a heat circulation system 300, and a heater 400; wherein, the wheel arch body 100 is disposed on the vehicle body 200 and is located above the wheel; the heat circulation system 300 is disposed in the vehicle body 200 and is connected to at least one of the engine 230 and the battery 240; the heat circulation system 300 is disposed on a side of the wheel arch body 100 away from the wheel, and is configured to obtain heat released by at least one of the engine 230 and the battery 240 and transfer the obtained heat to the wheel arch body 100; the heater 400 is disposed in the wheel arch body 100; the heater 400 is configured to heat the wheel arch body 100.

[0032] As Figure 1 shown, the present application provides a wheel arch cleaning device for cleaning ice and snow accumulation layers on the inner side of a vehicle wheel arch; the wheel arch cleaning device includes a wheel arch body 100, a heat circulation system 300, and a heater 400; wherein, the wheel arch body 100 is disposed on the vehicle body 200, and can separate the internal structure of the body 200 from the wheel, preventing sand, silt, road surface water, etc. thrown out during the rotation of the wheel from entering the interior of the vehicle body 200.

[0033] Regarding the heat circulation system 300 of the vehicle, the heat circulation system 300 is disposed in the vehicle body 200 and can be connected to at least one of the vehicle engine 230 and the battery 240; when the vehicle is running, the engine 230 and the battery 240 of the vehicle generate a large amount of heat. To prevent the engine and the battery 240 from overheating, the heat circulation system 300 can be connected to the engine 230 and the battery 240 respectively, so as to transfer the heat of at least one of the engine 230 and the battery 240 to the heat circulation system 300, that is, obtain the heat of the engine 230 and / or the battery 240, and the heat can be exported through the heat circulation system 300 to reduce the operating temperature of the engine 230 and the battery 240; wherein, the heat circulation system 300 can reuse the received heat. For example, it can cooperate with the air conditioning system to deliver the heat to the cab for heating; in this embodiment, the heat circulation is located on a side of the wheel arch away from the wheel, and the heat obtained by the heat circulation system 300 can be transferred to the wheel arch body 100, so as to transfer the heat generated by the engine 230 and the battery 240 to the wheel arch body 100, causing the temperature of the wheel arch body 100 to rise; when ice and snow and other attachments adhere to the side of the wheel arch body 100 close to the wheel, as the temperature of the wheel arch body 100 rises, the ice and snow adhering to the wheel arch body 100 will also melt or fall off, preventing the formation of a thick and difficult-to-clean ice and snow accumulation layer.

[0034] In addition, a heater 400 is also provided inside the wheel arch body 100, which can actively heat the wheel arch body 100 to raise the temperature of the wheel arch body 100, so as to prevent a thick ice and snow accumulation layer from forming on the side of the wheel arch body 100 close to the wheel. Among them, regarding the heat circulation system 300 and the heater 400, the vehicle can use one of them to heat the wheel arch body 100, or when the heat in the heat circulation system 300 is insufficient, use the heat circulation system 300 and the heater 400 to heat the wheel arch simultaneously, which can not only ensure that the wheel arch body 100 obtains sufficient heat to quickly melt or shed the ice and snow attached to the wheel arch body 100, but also reduce the energy consumption of the vehicle for the wheel arch body 100 and improve the utilization rate of the waste heat of the vehicle.

[0035] Therefore, through the combined use of the heat circulation system 300 and the heater 400, the wheel arch cleaning device can heat the wheel arch body 100 under different conditions, thereby raising the temperature of the wheel arch body 100, melting or shedding in time the attachments such as ice and snow on the side of the wheel arch body 100 close to the wheel, avoiding the formation of a thick ice and snow accumulation layer, facilitating the reduction of the cleaning difficulty of the ice and snow accumulation layer, preventing the wheel arch body 100 from being corroded or damaged by ice and snow, and enhancing the driving experience and driving safety of users.

[0036] In some embodiments, the heat circulation system 300 includes: a heat exchanger 310, a circulation pipeline 320, a heat conduction pipeline 330, and a heat conduction structure 340. Among them, the heat exchanger 310 is arranged inside the vehicle body 200 and is connected to at least one of the engine 230 and the battery 240; the circulation pipeline 320 is communicated with the heat exchanger 310; the heat conduction pipeline 330, both ends of the heat conduction pipeline 330 are communicated with the circulation pipeline 320; the heat conduction structure 340 is arranged on the heat conduction pipeline 330; the heat conduction structure 340 is arranged on the side of the wheel arch body 100 away from the wheel.

[0037] Such as Figure 2 and Figure 3As shown, for the thermal cycling system 300, heat generated during the operation of the vehicle engine 230 and the battery 240 can be obtained through the thermal cycling system 300, and the obtained heat is used to heat the wheel arch body 100, so that the temperature of the wheel arch body 100 rises, preventing a thick ice and snow accumulation layer from forming on the side of the wheel arch body 100 close to the wheel; specifically, the thermal cycling system 300 may include a heat exchanger 310, a circulation pipeline 320, a heat conduction pipeline 330, and a heat conduction structure 340; among them, the heat exchanger 310 is arranged in the vehicle body 200 and has a connection relationship with at least one of the engine 230 and the battery 240. When the engine 230 or the battery 240 is operating, the heat exchanger 310 can collect the heat generated by the engine 230 or the battery 240 through a heat exchange medium and transfer the heat to the coolant flowing in the circulation pipeline 320. At this time, a circulation pump (not marked in the figure) provided on the circulation pipeline 320 is used to convey the coolant to utilize the heat or dissipate it into the external environment; more specifically, the coolant in the circulation pipeline 320 can flow into the heat conduction pipeline 330. Since the heat conduction pipeline 330 is provided with a heat conduction structure 340, and the heat conduction structure 340 is located on the side of the wheel arch body 100 away from the wheel and is used to heat the wheel arch body 100; that is, the coolant flowing into the heat conduction pipeline 330 can transfer the carried heat to the heat conduction structure 340, and then the heat conduction structure 340 transfers the heat to the wheel arch body 100 to utilize the excess heat in the vehicle, so that the temperature of the wheel arch body 100 rises and the formation of a thick ice and snow accumulation layer is inhibited.

[0038] In some embodiments, at least one of the two ends of the heat conduction pipeline 330 is provided with a cut-off valve 350 for controlling the channel state of the heat conduction pipeline 330; as Figure 1 shown, when the vehicle engine 230 and the battery 240 generate more heat; or when the vehicle is traveling in a low-temperature environment, the road surface water and ice and snow thrown by the rotating wheel to the side of the wheel arch body 100 close to the wheel are likely to freeze on its surface and form an ice and snow accumulation layer. At this time, the cut-off valve 350 can be controlled to switch to the open state, so that the coolant flows into the heat conduction pipeline 330 and the heat conduction structure 340 is used to heat the wheel arch body 100, and at the same time, the heat loss speed is also accelerated; when the thermal cycling system 300 cannot consume heat to inhibit the ice and snow accumulation layer; or when the vehicle is traveling in a high-temperature environment, that is, an ice and snow accumulation layer will not form on the side of the wheel arch body 100 close to the wheel. At this time, when the thermal cycling system 300 does not heat the wheel arch body 100, the cut-off valve 350 can be controlled to switch to the closed state to prevent the coolant carrying heat from flowing into the heat conduction pipeline 330 to avoid waste of heat.

[0039] In some embodiments, the heat conduction structure 340 includes: a plurality of heat exchange plates 3411; the plurality of heat exchange plates 3411 are disposed on the heat conduction pipeline 330; the plurality of heat exchange plates 3411 are disposed on the side of the wheel arch body 100 away from the wheel; in the direction from the front end 210 of the vehicle body 200 to the rear end 220 of the vehicle body 200, the distance between two adjacent heat exchange plates 3411 gradually decreases.

[0040] As Figure 2 and Figure 3 As shown, the heat conduction structure 340 is disposed on the heat conduction pipeline 330 and on the side of the wheel arch body 100 away from the wheel. When the coolant in the circulation pipeline 320 of the heat circulation system 300 flows into the heat conduction pipeline 330, it also transfers heat to the heat conduction structure 340, so that the heat conduction structure 340 heats the wheel arch body 100; specifically, the heat conduction structure 340 may include a plurality of heat exchange plates 3411; the plurality of heat exchange plates 3411 are disposed on the heat conduction pipeline 330 and on the side of the wheel arch body 100 away from the wheel. At this time, the wheel arch body 100 can block and protect the heat conduction structure 340, and the heat conduction structure 340 can transfer heat to the wheel arch body 100 through the heat exchange plates 3411 to heat the wheel arch body 100 and increase its temperature.

[0041] More specifically, a plurality of heat exchange plates 3411 for heating the wheel arch body 100 are disposed on the side of the wheel arch body 100 away from the substrate; among them, when the vehicle is driving, it will pick up attachments such as road surface water and ice and snow, and the wheel will throw them to the side of the wheel arch body 100 close to the wheel. Under the action of inertia, most of the road surface water or ice and snow thrown to and attached to the wheel arch body 100 are concentrated in the area of the wheel arch body 100 close to the rear end 220, that is, there is more ice and snow in the area of the wheel arch body 100 close to the rear end 220, and it is easy to form a relatively thick ice and snow accumulation layer, while there is less ice and snow in the area of the wheel arch body 100 close to the front end 210. Therefore, it is necessary to give priority to cleaning the ice and snow in the area of the wheel arch body 100 close to the rear end 220; assuming that the direction from the front end 210 of the vehicle body 200 to the rear end 220 of the vehicle body 200 is the X direction, along the X direction, the distance between two adjacent heat exchange plates 3411 can be gradually decreased, so that the heat received by the wheel arch body 100 along the X direction is also more and more. At this time, it is not easy to generate a relatively thick ice and snow accumulation layer in the area of the wheel arch body 100 close to the rear end 220, so as to improve the utilization rate of the heat in the heat circulation system 300 of the vehicle.

[0042] In some embodiments, the heat conduction structure 340 includes: a plurality of fins 3421 and a blower 3422; the plurality of fins 3421 are arranged along the extending direction of the heat conduction pipeline 330; the extending direction of the heat conduction pipeline 330 is adapted to the extending direction of the wheel arch body 100, and from the front end 210 of the vehicle body 200 to the rear end 220 of the vehicle body 200, the distance between two adjacent fins 3421 gradually decreases; the blower 3422 is located above the plurality of fins 3421; the blower 3422 is configured to transfer the heat released by the fins 3421 to the wheel arch body 100.

[0043] As Figure 4 and Figure 5 shown, since the heat circulation system 300 transfers heat to the heat conduction structure 340 through the heat conduction pipeline 330 to utilize the heat conduction structure 340 to heat the wheel arch body 100 to reduce the probability of forming a thick ice and snow layer; specifically, the heat conduction structure 340 may include a plurality of fins 3421 and a blower 3422; wherein, the extending direction of the heat conduction pipeline 330 is adapted to the extending direction of the wheel arch body 100, and the plurality of fins 3421 are arranged along the extending direction of the heat conduction pipeline 330, so that the coolant flowing through the heat conduction pipeline 330 transfers heat to the fins 3421, and the fins 3421 can dissipate the heat in the heat conduction pipeline 330, and the blower 3422 is located above the plurality of fins 3421. When the blower 3422 operates, it can generate an air flow towards the heat dissipation fins 3421 and blow to the surface of the wheel arch body 100 to transfer the heat dissipated by the heat dissipation fins 3421 to the wheel arch body 100, so that the temperature of the wheel arch body 100 rises.

[0044] More specifically, since a heat conduction pipeline 330 adapted thereto is provided on the side of the wheel arch body 100 away from the substrate, and a plurality of fins 3421 for heating the wheel arch body 100 are sequentially arranged on the heat conduction pipeline 330; based on the above embodiments, during the driving of the vehicle, there is more ice and snow in the area of the wheel arch body 100 close to the rear end 220, and it is easy to form a thick ice and snow layer, while there is less ice and snow in the area of the wheel arch body 100 close to the front end 210. Therefore, the ice and snow in the area of the wheel arch body 100 close to the rear end 220 should be preferentially cleared; therefore, similarly, the direction from the front end 210 of the vehicle body 200 to the rear end 220 of the vehicle body 200 is set as the X direction. Along the X direction, the distance between two adjacent fins 3421 can be gradually decreased, so that the heat received by the wheel arch body 100 along the X direction is also increasing. At this time, it is not easy to form a thick ice and snow layer in the area of the wheel arch body 100 close to the rear end 220, so as to improve the utilization rate of heat in the heat circulation system 300.

[0045] In some embodiments, the heater 400 includes: a plurality of linearly heating portions 410 connected in sequence, with two adjacent linearly heating portions 410 being parallel to each other; in the direction from the front end 210 of the vehicle body 200 to the rear end 220 of the vehicle body 200, the distance between two adjacent linearly heating portions 410 gradually decreases.

[0046] As Figure 2 , Figure 4 and Figure 6 shown, the wheel arch cleaning device is further provided with a heater 400, which actively heats the wheel arch body 100 through the heater 400, so as to assist in heating the wheel arch body 100 when the heat circulation system 300 is not sufficient to provide sufficient heat to the wheel arch body 100; wherein, the wheel arch body 100 may include a plurality of linearly heating portions 410 connected in sequence, and two adjacent linearly heating portions 410 are parallel to each other, ensuring the heating efficiency of the heater 400 for the wheel arch body 100; exemplarily, the heater 400 may adopt a heating wire, and the heating wire may be serpentinely arranged inside the wheel arch body 100, and each portion of the heating wire that is used for heating and is parallel to each other serves as the linearly heating portion 410, so as to ensure that the heating wire has good heating efficiency and is beneficial to quickly raising the temperature of the wheel arch body 100.

[0047] More specifically, based on the above embodiments, it can be known that during the driving process of the vehicle, there is more ice and snow in the area of the wheel arch body 100 close to the rear end 220, and it is easy to form a relatively thick ice and snow accumulation layer, while there is less ice and snow in the area of the wheel arch body 100 close to the front end 210. Therefore, the ice and snow in the area of the wheel arch body 100 close to the rear end 220 should be preferentially cleaned; therefore, similarly, the direction from the front end 210 of the vehicle body 200 to the rear end 220 of the vehicle body 200 is set as the X direction. Along the X direction, the distance between two adjacent linearly heating portions 410 can be gradually decreased, so that the heating effect of the wheel arch body 100 along the X direction is also increasing. At this time, it is not easy to generate a relatively thick ice and snow accumulation layer in the area of the wheel arch body 100 close to the rear end 220, and at the same time, it is beneficial to reduce the energy consumption during the heating process.

[0048] In some embodiments, the wheel arch cleaning device further includes: a controller 500, and the controller 500 is respectively connected to the heat circulation system 300 and the heater 400; the controller 500 is configured to control at least one of the heat circulation system 300 and the heater 400 to heat the wheel arch body 100.

[0049] As Figure 7As shown, with regard to the wheel arch cleaning device, the wheel arch cleaning device may further include a controller 500, and the controller 500 is respectively connected to the heat circulation system 300 and the heater 400, so that the controller 500 can control at least one of the heat circulation system 300 and the heater 400 to heat the wheel arch body 100 according to actual conditions, which is beneficial to control the power consumption consumed when heating the wheel arch body 100, and ensure the timeliness and reliability of heating the wheel arch body 100.

[0050] In some embodiments, the wheel arch cleaning device further includes: a gravity sensor 700, which is connected to the side of the wheel arch body 100 away from the wheel and is connected to the controller 500; the gravity sensor 700 is configured to obtain gravity information of attachments attached to the side of the wheel arch body 100 close to the wheel.

[0051] like Figure 7 As shown, with regard to the wheel arch cleaning device, the wheel arch cleaning device may include a gravity sensor 700, and the gravity sensor 700 is connected to the side of the wheel arch body 100 away from the wheel; wherein, since the attachments will cause a slight deformation when attached to the wheel arch body 100, and the deformation can cause a change in the measurement threshold of the gravity sensor 700, the attachment gravity of the ice and snow layer on the wheel arch body 100 can be determined; specifically, the gravity sensor 700 can be used to obtain the gravity information of the attachments attached to the side of the wheel arch body 100 close to the wheel. When the gravity information of the attachments obtained by the gravity sensor 700 is less than the preset gravity threshold, it means that the attachment amount of the attachments is large, and it has an adverse effect on the rotation of the wheel and the overall structure of the wheel arch body 100. At this time, the wheel arch body 100 can be heated in time, which is beneficial to improve the cleaning efficiency and cleaning timeliness of the attachments.

[0052] In some embodiments, the wheel arch cleaning device further includes: a temperature sensor 600, which is disposed on the side of the wheel arch body 100 close to the wheel; the temperature sensor 600 is configured to obtain temperature information of attachments attached to the side of the wheel arch body 100 close to the wheel.

[0053] like Figure 2 , Figure 4 as well as Figure 7As shown in the figure, for the wheel arch cleaning device, the wheel arch cleaning device may include a temperature sensor 600, and the temperature sensor 600 is disposed on one side of the wheel arch body 100 close to the wheel; wherein, since the temperature of the ice and snow accumulation layer is relatively low, the temperature sensor 600 can be used to obtain the temperature information of the attachment on one side of the wheel arch body 100 close to the wheel, and the self-temperature of the wheel arch body 100 can also be detected; when the temperature information of the attachment obtained by the temperature sensor 600 is less than the preset temperature threshold, it indicates that the probability of the attachment being an ice and snow accumulation layer is relatively high, and combined with the gravity information obtained by the gravity sensor 700, the accuracy of the judgment of the attachment type can be improved, which is beneficial to the timely cleaning of the attached ice and snow; it should be noted that the temperature sensor 600 can be disposed in the area of the wheel arch body 100 close to the vehicle tail 220, which is beneficial to further improve the measurement accuracy of the attachment temperature.

[0054] The working principle of the wheel arch cleaning device will be elaborated in combination with the above embodiments, and the specific process is as follows:

[0055] Example 1, the wheel arch cleaning device may have an automatic cleaning mode:

[0056] The gravity sensor 700 can be used to obtain the gravity information of the attachment on one side of the wheel arch body 100 close to the wheel, and the temperature sensor 600 can be used to obtain the temperature information of the attachment on one side of the wheel arch body 100 close to the tire, and both can transmit the obtained gravity information and temperature information to the vehicle controller 500 through the bus; in one case, when the controller 500 detects that the gravity information of the attachment is greater than or equal to the preset gravity threshold, and the temperature of the attachment on one side of the wheel arch body 100 close to the tire is less than or equal to the preset temperature threshold (the preset temperature threshold can be set to any temperature value within the range of 0-5 °C), it indicates that the attachment on the wheel arch body 100 is ice and snow. At this time, the controller 500 can control the wheel arch cleaning system to switch to the automatic cleaning mode, that is, use the heat circulation system 300 to collect the heat of at least one of the vehicle engine 230 and the battery 240, and transport it to each wheel arch body 100 through the heat circulation pipeline 320 for heating. When the temperature sensor 600 detects that the wheel arch body 100 is heated by the heat released by the heat circulation system 300 to be greater than the preset temperature threshold, the controller 500 can control the heat circulation system 300 to terminate heating the wheel arch to reduce heat waste.

[0057] In another case, when the thermal cycling system 300 has no excess heat (for example, at least part of the heat in the thermal cycling system 300 is used for heating the cab), the controller 500 can control the activation of the auxiliary heating function and use the heater 400 to perform auxiliary heating on the wheel arch body 100 until the wheel arch body 100 is heated to be greater than or equal to a preset temperature threshold. At this time, the controller 500 can control the heater 400 to stop working and terminate the heating of the wheel arch to prevent a thick ice and snow accumulation layer from forming on the wheel arch body 100.

[0058] Example two, the wheel arch cleaning device can have a manual cleaning mode:

[0059] The user can manually control the wheel arch cleaning mode through a remote control or an operation panel in the cab to clean the ice and snow accumulation layer on the surface of the wheel arch body 100, that is, the heating process of the wheel arch body 100 is manually controlled; specifically, in one case, the user can send a start request for the manual cleaning mode to the controller 500. The controller 500 can control the thermal cycling system 300 to collect the heat of at least one of the vehicle engine 230 and the battery 240 and transport it to the wheel arch body 100 through the thermal cycling pipeline 320 for heating. When the temperature sensor 600 detects that the wheel arch body 100 is heated by the heat released by the thermal cycling system 300 to be greater than the preset temperature threshold, the controller 500 can automatically control the thermal cycling system 300 to terminate the heating of the wheel arch to reduce heat waste and reduce the power consumption of the vehicle running the thermal cycling system 300.

[0060] In another case, when the thermal cycling system 300 has no excess heat and the controller 500 receives a start request for the manual cleaning mode sent by the user, the controller 500 can control the activation of the auxiliary heating function and use the heater 400 to perform auxiliary heating on the wheel arch body 100 until the wheel arch body 100 is heated to be greater than or equal to a preset temperature threshold. At this time, the controller 500 can control the heater 400 to stop working and terminate the heating of the wheel arch body 100 to prevent a thick ice and snow accumulation layer from forming on the surface of the wheel arch body 100.

[0061] In addition, when the gravity information of the attachment obtained by the controller 500 is less than the preset gravity threshold, and / or the temperature of the attachment on the side of the wheel arch body 100 close to the tire is greater than the preset temperature threshold, there is no need to clean the ice and snow accumulation layer at this time to reduce the waste of vehicle power consumption; at this time, if the controller 500 receives a start request for the manual cleaning mode sent by the user, the controller 500 can ignore the start request and send a prompt message to the user through the vehicle-mounted computer or the mobile terminal, prompting the user that there is no need to clean the ice and snow accumulation layer.

[0062] Note that the controller 500 may include specially designed permanent circuits or logic devices (such as dedicated processors, such as FPGAs or ASICs) for performing specific operations. The controller 500 may also include programmable logic devices or circuits (such as including general-purpose processors or other programmable processors) temporarily configured by software for performing specific operations. As for whether to use dedicated permanent circuits or temporarily configured circuits (such as configured by software) to implement the controller 500, it can be determined based on cost and time considerations.

[0063] In some embodiments, the wheel arch cleaning device further includes: an anti-adhesion layer 800, which is disposed on the side of the wheel arch body 100 close to the wheel, and the shape of the anti-adhesion layer 800 is adapted to the shape of the wheel arch body 100.

[0064] Such as Figure 2 and Figure 4 As shown, when heating the wheel arch body 100 by at least one of the thermal cycling system 300 and the heater 400, the ice and snow will melt or detach from the side of the wheel arch body 100 close to the wheel after being heated; in order to reduce the adhesion of the ice and snow thrown towards the side of the wheel arch body 100 close to the wheel and improve the falling-off effect of the ice and snow after being heated, the wheel arch cleaning device further includes an anti-adhesion layer 800, which is disposed on the side of the wheel arch body 100 close to the wheel, and the shape of the anti-adhesion layer 800 is adapted to the shape of the wheel arch body 100, which can reduce the adhesion effect of the ice and snow on the surface of the wheel arch body 100 to reduce the probability of forming an ice and snow accumulation layer; wherein, the anti-adhesion layer 800 can be a coating formed by at least one of epoxy resin coatings, high-temperature ceramic coatings, and elastic polymer coatings, which can not only reduce the adhesion effect of the ice and snow on the inner side of the wheel arch body 100, but also has good waterproof performance, heat resistance performance, and scratch resistance performance, which is beneficial to extending the service life of the wheel arch body 100.
