TECHNICAL FIELD

[0001] The application belongs to the technical field of automobiles, and particularly relates to a wheel compartment heating device and a vehicle. BACKGROUND

[0002] When the vehicle travels in cold weather, the ice and snow on the road surface will be adhered to the wheel compartment of the vehicle under the driving action of the wheels, and then the ice and snow will be accumulated in the wheel compartment in a cluster or block shape, thereby increasing the weight of the wheel cover, so that the wheel cover is easily damaged. With the increasing travel distance of the vehicle, the volume of the ice and snow accumulated in the wheel compartment becomes larger and larger, and then the ice and snow accumulated in the wheel compartment may interfere with the wheels, which not only increases the driving resistance and driving noise of the vehicle, but also increases the damage risk of the wheel cover. In addition, with the increasing volume of the ice and snow accumulated in the wheel compartment, the ice and snow accumulated together will extend to the outside of the vehicle, so that the ice and snow extending to the outside of the vehicle may interfere with other components near the wheel cover, such as electric side steps, cameras, sensors, lamps, etc., thereby causing the components near the wheel cover to fail to operate normally, and the ice and snow extending to the outside of the vehicle will also affect the passability of the vehicle.

[0030] By adopting the technical scheme, since the communication pipe is provided with the control valve, the opening degree and closing of the communication pipe can be controlled by the control valve, so that when the wheel cover does not need to be heated, the control valve closes the communication pipe, so that the air filtered by the air filter module is all used by other components, and when the wheel cover needs to be heated, the opening degree of the communication pipe can be controlled by the control valve to adjust the flow of the gas entering the gas heating cavity, and then the heating effect and efficiency of the wheel cover are adjusted to ensure the normal operation of other functions of the vehicle while the heating of the wheel cover is realized.

[0031] Optionally, the heating cavity comprises a gas heating cavity and a liquid heating cavity, and the liquid heating cavity is located on the side of the gas heating cavity close to the wheel.

[0032] By adopting the technical scheme, since part of the liquid entering the liquid heating cavity does not exchange heat with the air, the temperature of the liquid heating cavity is higher than that of the gas heating cavity, so that the liquid heating cavity is arranged on the side of the gas heating cavity close to the wheel. On the one hand, the heating effect of the inner side of the wheel cover can be improved to improve the effect and efficiency of removing the ice and snow from the wheel cover, and on the other hand, the heat loss of the liquid heating cavity in the outward direction can be reduced, so that more heat participates in heating the inner side of the wheel cover to further improve the effect of removing the ice and snow from the wheel cover.

[0034] By adopting the above technical solution, when the vehicle is in motion, the wheels will throw ice and snow onto the side of the wheel arch away from the front of the vehicle. By placing the heating chamber on the side of the wheel arch away from the front of the vehicle, the heat is mainly concentrated on the side of the wheel arch away from the front of the vehicle, thereby increasing the temperature of the areas on the wheel arch where ice and snow tend to accumulate, and thus improving the effect and efficiency of the wheel arch in removing ice and snow.

[0056] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0057] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0058] Furthermore, it should be understood in the description of this application that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0059] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0060] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0061] Reference Figures 1 to 10 A wheel well heating device is disclosed, comprising a wheel cover 2 disposed on the vehicle body 1 and located on the outer periphery of the wheel 12, and a heat source assembly disposed on the vehicle body 1. The wheel cover 2 has a heating chamber inside, which includes at least a gas heating chamber 21 and / or a liquid heating chamber 22. The gas heating chamber 21 has at least one gas inlet 211 and a gas outlet 212. The gas inlet 211 is connected to an air filter module 3 so that the gas filtered by the air filter module 3 is heated by the heat source assembly and enters the gas heating chamber 21. The liquid heating chamber 22 has at least one liquid inlet 221 and a liquid outlet 222. Both the liquid inlet 221 and the liquid outlet 222 are connected to the heat source assembly so that the liquid is heated by the heat source assembly and enters the liquid heating chamber 22.

[0062] When a vehicle equipped with the wheel well heating device of this application is driven in cold weather, the air is filtered by the air filter module 3 and then heated by the heat source component. The air temperature rises and then enters the gas heating chamber 21 through the gas inlet 211, so that the heated air heats the wheel cover 2. And / or the liquid is heated by the heat source component and then enters the liquid heating chamber 22 through the liquid inlet 221, so that the heated liquid heats the wheel cover 2. This raises the temperature of the inner wall of the wheel cover 2, so that the ice and snow adhering to the inner wall of the wheel cover 2 melts and separates from the wheel cover 2. This avoids the phenomenon that ice and snow accumulate on the wheel cover 2, which would increase the load on the wheel cover 2, thus avoiding the phenomenon that the wheel cover 2 is easily damaged due to the heavy load, and ensuring the service life of the wheel cover 2.

[0063] At the same time, it avoids the phenomenon of ice and snow continuously accumulating on the wheel cover 2 and interfering with the wheel 12, thereby avoiding the phenomenon of increased vehicle driving resistance caused by the friction between the ice and snow accumulated on the wheel cover 2 and the wheel 12, and reducing vehicle driving noise, so as to improve the user's driving experience.

[0064] Furthermore, it avoids the phenomenon that excessive accumulation of ice and snow in the wheel wells extends to the outside of the vehicle body 1 and affects the normal operation of other components near the wheel well 2, thus ensuring the normal operation of other vehicle functions and the vehicle's passability; in addition, it avoids the phenomenon that users may damage the wheel well 2 or the paint by forcibly removing the ice and snow accumulated in the wheel wells, thereby improving the user experience.

[0065] Furthermore, when the wheel well heating device in this application uses gas to heat the wheel cover 2, the gas used is air filtered by the air filter module 3, which makes the gas cleaner. Compared with the solution of directly heating the outside air and then delivering it to the gas heating chamber 21, it greatly improves the cleanliness of the gas heating chamber 21, so as to avoid the phenomenon that dust in the air adheres to the cavity wall of the gas heating chamber 21 and affects the flow area of ​​the gas heating chamber 21, thereby ensuring the effect and heating efficiency of heating the wheel cover 2 with gas.

[0066] This application does not specifically limit the structure of the air filter module 3. For fuel vehicles or hybrid vehicles, the air filter module 3 can be an air filter or an air conditioning filter to filter the outside air, thereby ensuring the cleanliness of the gas heating chamber 21. For pure electric vehicles, the air filter module 3 can be an air conditioning filter.

[0067] In a preferred embodiment, the heat source assembly includes a heat source structure and a heat exchange structure 4 connected to the heat source structure. The heat exchange structure 4 uses the heat from the heat source structure to heat the gas entering the gas heating chamber 21 and / or the liquid entering the liquid heating chamber.

[0068] When the wheel cover 2 is heated, the heat source structure generates heat. The heat exchange structure 4 uses the heat from the heat source structure to heat the air about to enter the gas heating chamber 21 and / or the liquid about to enter the liquid heating chamber 22. This causes the air temperature to rise before entering the gas heating chamber 21 and / or the liquid temperature to rise before entering the liquid heating chamber 22, thus using the increased temperature of the air and / or liquid to heat the wheel cover 2. By setting up the heat exchange structure 4, efficient heating of the gas or liquid can be achieved, thereby improving the heating effect and efficiency of the wheel cover 2, and ultimately achieving the effect of rapid de-icing of the wheel cover 2.

[0069] This application does not impose specific limitations on the heat source structure, which can adopt any of the following embodiments:

[0070] Example 1, in this example, refers to Figure 1The heating chamber includes a gas heating chamber 21, and the heat source components include an engine 5 and an exhaust gas treatment module 51 connected to the exhaust port of the engine 5. The air inlet of the heat exchange structure 4 is connected to the exhaust port of the exhaust gas treatment module 51, and the gas inlet 211 is connected to the air outlet of the heat exchange structure 4.

[0071] It is understood that the heat exchange structure 4 has a high-temperature medium channel and a low-temperature medium channel. In this embodiment, the high-temperature medium is the high-temperature exhaust gas generated when the engine 5 is working, and the low-temperature medium is the air filtered by the air filter module 3. The air inlet of the high-temperature medium channel is connected to the exhaust port of the exhaust gas treatment module 51, the air filter module 3 is connected to the air inlet of the low-temperature medium channel, and the gas inlet 211 is connected to the air outlet of the low-temperature medium channel. Thus, the air filtered by the air filter module 3 absorbs the heat of the high-temperature exhaust gas in the heat exchange structure 4 and enters the gas heating chamber 21 to heat the wheel cover 2, thereby melting the ice and snow accumulated on the wheel cover 2 and separating it from the wheel cover 2.

[0072] Furthermore, a silencing module 52 is connected downstream of the exhaust gas treatment module 51. That is, part of the high-temperature exhaust gas after being treated by the exhaust gas treatment module 51 enters the heat exchange structure 4, and the remaining part directly enters the silencing module 52, so that the silencing module 52 can directly discharge the high-temperature exhaust gas into the atmosphere after silencing treatment, thereby reducing the noise generated by the vehicle.

[0073] This application does not specify the exhaust method of the high-temperature medium channel outlet of the heat exchange structure 4. It can be connected to the upstream of the silencer module 52 through a pipeline so that the high-temperature exhaust gas after the air is heated is directly discharged into the atmosphere after being silenced by the silencer module 52; or the outlet of the high-temperature medium channel can be directly connected to the atmosphere so that the high-temperature exhaust gas after the gas is heated is directly discharged into the atmosphere.

[0074] In this embodiment, preferably, the heat exchange structure 4 is a heat pipe heat exchanger, so that the air filtered by the air filter module 3 can efficiently exchange heat with the high-temperature exhaust gas in the heat pipe heat exchanger. Of course, the heat exchange structure 4 can also be other structures that can use high-temperature exhaust gas to heat the air.

[0075] Preferably, a control valve 311 is provided on the pipeline connecting the exhaust gas treatment module 51 and the heat exchange structure 4, so as to control the connection or disconnection between the exhaust gas treatment module 51 and the heat exchange structure 4.

[0076] Example 2, the difference between this example and Example 1 is that, referring to... Figure 3The heating chamber includes a liquid heating chamber 22. The heat source assembly also includes a liquid storage tank 6 for holding liquid and a delivery pump 61 connected to the liquid storage tank 6. The air inlet of the heat exchange structure 4 is connected to the exhaust port of the exhaust gas treatment module 51. The delivery pump 61 is connected to the liquid outlet 222. The liquid storage tank 6 is connected to the liquid inlet of the heat exchange structure 4. The liquid inlet 221 is connected to the liquid outlet of the heat exchange structure 4.

[0077] It is understood that the heat exchange structure 4 has a high-temperature medium channel and a low-temperature medium channel. In this embodiment, the high-temperature medium is the high-temperature exhaust gas generated when the engine 5 is working, and the low-temperature medium is the liquid contained in the liquid storage tank 6. The air inlet of the high-temperature medium channel is connected to the exhaust port of the exhaust gas treatment module 51, the liquid storage tank 6 is connected to the liquid inlet of the low-temperature medium channel, and the liquid inlet 221 is connected to the liquid outlet of the low-temperature medium channel. Thus, the high-temperature exhaust gas treated by the exhaust gas treatment module 51 enters the high-temperature medium channel, and the liquid contained in the liquid storage tank 6 enters the low-temperature medium channel under the action of the delivery pump 61, so that the liquid absorbs the heat of the high-temperature exhaust gas in the heat exchange structure 4, thereby raising the temperature of the liquid. The heated liquid enters the liquid heating chamber 22 through the liquid inlet 221, thereby heating the wheel cover 2.

[0078] In this embodiment, preferably, the heat exchange structure 4 is a heat exchanger, so that the liquid and the high-temperature exhaust gas can exchange heat efficiently in the heat exchanger. Of course, the heat exchange structure 4 can also be other structures that can use high-temperature exhaust gas to heat the liquid.

[0079] It should be noted that the solutions of Embodiments 1 and 2 described above can be applied not only to fuel vehicles but also to hybrid vehicles.

[0080] Of course, in some other embodiments, the heating chamber includes a gas heating chamber 21 and a liquid heating chamber 22, and two heat exchange structures 4 are provided. One heat exchange structure 4 uses high-temperature exhaust gas to heat the air filtered by the air filter module 3, and the other heat exchange structure 4 uses high-temperature exhaust gas to heat the liquid. That is to say, in this embodiment, the solution is formed by combining the solutions of the above embodiments 1 and 2; or, the heat source structure is a cooling system for cooling the engine, battery pack or motor.

[0081] In addition to the heat exchange structure 4 shown in the above embodiments for heat exchange of gas or liquid, the wheel hub structure in this application can also adopt any of the following embodiments:

[0082] Example 3, in this example, refer to Figure 4 , Figure 5 and Figure 6The heating chamber includes a liquid heating chamber 22, and the heat source assembly includes a cooling module 7 for holding liquid and an engine 5 and / or battery pack 8. The liquid inlet 221 is connected to the liquid outlet of the engine 5 and / or battery pack 8, the liquid outlet 222 is connected to the liquid inlet of the cooling module 7, and the liquid outlet of the cooling module 7 is connected to the liquid inlet of the engine 5 and / or battery pack 8.

[0083] It should be noted that this embodiment actually includes three solutions: 1. A solution applicable to fuel vehicles or hybrid vehicles that utilizes the heat generated by the engine 5 during operation to heat the wheel arch 2 (e.g., Figure 4 (as shown); II. A solution that can be applied to pure electric vehicles or hybrid vehicles and utilizes the heat generated by the battery pack 8 during operation to heat the wheel arch 2 (e.g.) Figure 5 (as shown); III. A scheme that utilizes the heat generated by both the engine 5 and the battery pack 8 during operation in a hybrid vehicle to heat the wheel arch 2 (e.g. Figure 6 (As shown).

[0084] When heating the wheel arch 2, the liquid in the cooling module 7 passes through the engine 5 and / or battery pack 8, thereby absorbing heat from the engine 5 and / or battery pack 8 to lower its temperature and achieve cooling. Simultaneously, the liquid temperature rises, and the heated liquid enters the liquid heating chamber 22, further heating the wheel arch 2. This utilizes the liquid used to cool the engine 5 and / or battery pack 8 to heat the wheel arch 2, improving the cooling effect of the liquid while maintaining heating efficiency and effectiveness. This shortens the start-up time of the cooling fan in the cooling module 7, thus reducing vehicle energy consumption. Furthermore, compared to requiring a separate component for heating the liquid, this reduces vehicle production costs.

[0085] This application does not specifically limit the structure of the cooling module 7. For fuel vehicles or hybrid vehicles, it can be the cooling system of the engine 5. For turbocharged engines 5, it can not only be the cooling system of the engine 5, but also an intercooler for cooling the intake air of the engine 5. That is to say, the liquid is the coolant contained in the cooling module 7. For pure electric vehicles and hybrid vehicles, it can also be the cooling system of the battery pack 8 or the cooling system of the motor.

[0086] Example 4, the difference between this example and Example 3 is that, referring to... Figure 7The heating chamber also includes a gas heating chamber 21, and the heat source assembly also includes a heat exchange structure 4. The air inlet of the heat exchange structure 4 is connected to the air filter module 3, the air outlet of the heat exchange structure 4 is connected to the gas inlet 211, the liquid inlet of the heat exchange structure 4 is connected to the connecting pipe between the liquid outlet of the engine 5 and / or the battery pack 8 and the liquid inlet 221, and the liquid outlet of the heat exchange structure 4 is connected to the liquid inlet 221.

[0087] It should be noted that, like embodiment 3, this embodiment also includes three schemes: heating the wheel cover 2 using the heat of engine 5, heating the wheel cover 2 using the heat of battery pack 8, and heating the wheel cover 2 using the heat of both engine 5 and battery pack 8.

[0088] In the scheme where the heat generated by the engine 5 alone is used to heat the wheel cover 2, two liquid inlets 221 are provided. One liquid inlet 221 is connected to the liquid outlet of the engine 5, and the other liquid inlet 221 is connected to the liquid outlet of the heat exchange structure 4. In the scheme where the heat generated by the battery pack 8 alone is used to heat the wheel cover 2, two liquid inlets 221 are also provided. One liquid inlet 221 is connected to the liquid outlet of the battery pack 8, and the other liquid inlet 221 is connected to the liquid outlet of the heat exchange structure 4. In the scheme where the heat generated by the engine 5 and the battery pack 8 are used to heat the wheel cover 2, three liquid inlets 221 are provided. One liquid inlet 221 is connected to the liquid outlet of the engine 5, another liquid inlet 221 is connected to the liquid outlet of the battery pack 8, and the last liquid inlet 221 is connected to the liquid outlet of the heat exchange structure 4.

[0089] When de-icing the wheel cover 2, the liquid in the cooling module 7 enters the engine 5 and / or battery pack 8, thereby cooling the engine 5 and / or battery pack 8. This allows the liquid to absorb heat from the engine 5 and / or battery pack 8, increasing its temperature. A portion of the heated liquid then directly enters the liquid heating chamber 22 to heat the wheel cover 2. The remaining liquid enters the heat exchange structure 4 and heats the gas filtered by the air filter module 3, increasing its temperature. The heated gas then enters the gas heating chamber 21, and the liquid that has completed heat exchange with the gas also enters the liquid heating chamber 22. This gas-liquid coupling method heats the wheel cover 2, improving the heating effect and efficiency, and thus enhancing the de-icing effect of the wheel cover 2.

[0090] Example 5, the difference between this example and Example 4 is that, referring to... Figure 9The heat source assembly also includes a braking module 9, a liquid storage tank 6 for holding liquid, and a delivery pump 61 connected to the liquid storage tank 6. The braking module 9 has a braking friction pad 91, the liquid storage tank 6 is connected to the braking friction pad 91, the liquid inlet 221 is connected to the delivery pump 61, and the liquid outlet 222 is connected to the liquid storage tank 6.

[0091] When the vehicle brakes, the brake module 9 generates heat. By connecting the reservoir 6 to the brake pads 91, the heat generated by the brake pads 91 during braking can be transferred to the liquid in the reservoir 6. This improves the cooling effect of the brake pads 91 to ensure the vehicle's braking performance, and also heats the liquid. The increased temperature of the liquid allows it to enter the liquid heating chamber 22 through the liquid inlet 221 under the action of the delivery pump 61, thereby heating the wheel cover 2. Ultimately, this melts the ice and snow accumulated on the wheel cover 2 and separates it from the wheel cover 2, thus removing ice and snow from the wheel cover 2.

[0092] Furthermore, when heating the wheel cover 2, the wheel cover 2 can be heated by the braking module 9 and / or the cooling module 7, thereby increasing the flexibility of heating the wheel cover 2 and avoiding the phenomenon that the wheel cover 2 cannot be heated due to a failure of one of the methods, so as to ensure the normal operation of the de-icing and snow removal function of the wheel cover 2.

[0093] In this embodiment, the connection method between the liquid storage tank 6 and the brake friction pad 91 is not specifically limited. Preferably, the brake friction pad 91 has a connecting channel inside, one end of which is connected to the liquid storage tank 6, and the other end of which is connected to the delivery pump 61 or the liquid storage tank 6, so that the liquid contained in the liquid storage tank 6 can be heated by the brake friction pad 91. In other embodiments, the brake module 9 has a cooling chamber, the brake friction pad 91 is disposed in the cooling chamber, and the liquid storage tank 6 is connected to the cooling chamber.

[0094] Furthermore, refer to Figure 9 The liquid storage tank 6 is connected to the delivery pump 61 via a first pipeline 62. The first pipeline 62 is equipped with a first control valve 621 for controlling the opening of the first pipeline 62. The cooling module 7 is connected to the liquid heating chamber 22 via a second pipeline 71. The second pipeline 71 is equipped with a second control valve 711 for controlling the opening of the second pipeline 71. Thus, the opening or closing of the first pipeline 62 can be controlled by the first control valve 621, and the opening or closing of the second pipeline 71 can be controlled by the second control valve 711, so as to realize the control and distribution of the liquid heating effect of the cooling module 7 and the braking module 9, thereby increasing the flexibility of the wheel well heating device and ensuring the performance of the vehicle.

[0095] It should be noted that, in this embodiment, the liquid outlet of the engine 5 and / or battery pack 8, which is the same as in embodiment 3, can be directly connected to the liquid inlet 221, and the liquid outlet 22 can be directly connected to the liquid inlet of the cooling module 7, so that the liquid flowing out of the engine 5 and / or battery pack 8 can directly enter the liquid heating chamber 22, and then flow into the cooling module 7 after heating the wheel cover 2; or, the liquid outlet 22 can be connected to the liquid inlet of the cooling module 7, and the liquid outlet of the cooling module 7 can be connected to the liquid storage tank 6, so that the high-temperature liquid in the cooling module 7 can first enter the liquid storage tank 6, and then enter the liquid heating chamber 22 under the action of the delivery pump 61, and finally enter the cooling module 7.

[0096] Example 6, in this example, refer to Figure 10 The heat source assembly includes an electric heating element 10 and a battery pack 8 for providing electrical energy to the electric heating element 10. The electric heating element 10 is disposed in a pipeline connected to a gas inlet 211 and / or a liquid inlet 221.

[0097] It is understood that this embodiment actually includes three solutions: 1. Heating the gas using the electric heating element 10; 2. Heating the liquid using the electric heating element 10; 3. Heating both the gas and the liquid using the electric heating element 10.

[0098] In the case of heating gas using electric heating element 10, gas inlet 211 is connected to air filter module 3 through connecting pipe 31. Electric heating element 10 is provided in connecting pipe 31 so that electric heating element 10 heats the gas flowing through connecting pipe 31. In this case, electric heating element 10 can be heating wire or PTC (Positive Temperature Coefficient) heater or other structures that can heat the gas in connecting pipe 31.

[0099] In the case of heating liquid using electric heating element 10, electric heating element 10 is provided in the pipeline for conveying liquid or the liquid storage tank 6 for holding liquid, so that electric heating element 10 heats the pipeline for conveying liquid or the liquid storage tank 6. In this case, electric heating element 10 is electric heating tube or other structure that can heat pipeline or liquid storage tank 6.

[0100] For the scheme of heating gas and liquid using electric heating element 10, two electric heating elements 10 are provided, which are respectively located in the pipeline for conveying gas and the pipeline for conveying liquid or the liquid storage tank 6 for holding liquid. In this scheme, one electric heating element 10 is a heating wire, a PTC heater or other structure that can heat gas, and the other electric heating element 10 is a heating tube or other structure that can heat liquid.

[0101] It should be noted that the solution in this embodiment can be applied to pure electric vehicles or hybrid vehicles.

[0102] In the above-described scheme of heating the wheel cover 2 with gas, the gas inlet 211 is connected to the air filter module 3 through the connecting pipe 31. The connecting pipe 31 is equipped with a control valve 311 to control the opening of the connecting pipe 31. The control valve 311 can control the opening and closing of the connecting pipe 31 so that when heating the wheel cover 2 is not required, the control valve 311 closes the connecting pipe 31 so that all the air filtered by the air filter module 3 can be used by other components. When heating the wheel cover 2 is required, the control valve 311 can control the opening of the connecting pipe 31 to adjust the gas flow rate into the gas heating chamber 21, thereby adjusting the heating effect and heating efficiency of the wheel cover 2, so as to achieve heating of the wheel cover 2 while ensuring the normal operation of other vehicle functions.

[0103] This application does not specifically limit the structure of control valve 311, first control valve 621 and second control valve 711. Preferably, they are solenoid valves to achieve automatic control; in other embodiments, they may be other valve bodies.

[0104] In the above-described scheme of heating the wheel cover 2 using gas and liquid, the liquid heating chamber 22 is located on the side of the gas heating chamber 21 closer to the wheel 12. Since gas loses heat faster than liquid, the temperature of the gas entering the gas heating chamber 21 is lower than the temperature of the liquid entering the liquid heating chamber 22. Therefore, placing the liquid heating chamber 22 on the side of the gas heating chamber 21 closer to the wheel 12 can improve the heating effect on the inner side of the wheel cover 2, thereby improving the effect and efficiency of removing ice and snow from the wheel cover 2. On the other hand, it can also reduce the heat loss of the liquid heating chamber 22 in the outward direction, so that more heat can participate in heating the inner side of the wheel cover 2, thereby further improving the effect of removing ice and snow from the wheel cover 2.

[0105] This application does not specifically limit the location of the heating chamber. Preferably, the wheel 12 has a center line extending vertically, and the heating chamber is located on the side of the center line away from the front of the vehicle. Since the wheel 12 will throw ice and snow into the wheel compartment when the vehicle is in motion, and the heating chamber is located on the side of the center line away from the front of the vehicle, the heat is mainly concentrated on the side of the wheel cover 2 away from the front of the vehicle, thereby increasing the temperature of the areas on the wheel cover 2 where ice and snow are easily accumulated, and thus improving the effect and efficiency of the wheel cover 2 in removing ice and snow.

[0106] In other embodiments, the heating cavity may also extend along the arc direction of the wheel cover 2.

[0107] Preferably, the wheel well heating device also includes an electronic control unit 11, which controls the operation of various electronic components of the wheel well heating device to control the heating of the wheel cover 2 according to the external environmental conditions.

[0108] Reference Figure 11 This application also discloses a vehicle including a body 1, wheels 12 and a wheel well heating device as described above. The body 1 has a wheel well, at least a portion of the wheels 12 is located in the wheel well, and the wheel well heating device is disposed in the wheel well.

[0109] Because the vehicle in this application uses the aforementioned wheel well heating device, the wheel cover 2 of the vehicle can automatically remove ice and snow, thereby ensuring the vehicle's passability and the service life of the wheel cover 2, reducing the vehicle's failure rate, and thus improving the user experience.

[0110] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0111] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0112] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
