[0022] In order to achieve the above technical objectives, this application adopts the following technical solutions: In a first aspect, the present application provides a vehicle fender, such as Figure 1 As shown, Figure 1 It is a structural schematic diagram of a vehicle fender provided in an embodiment of the present application.

[0023] A vehicle fender includes a fender body 1, an anti-splash device 2, a heating device 3, an energy supply device, a fender bracket 6 and a detection device 7: Mudguard body 1; An anti-splash device 2, the anti-splash device 2 is located on the inner side of the fender body 1; A heating device 3, wherein the heating device 3 is located inside the anti-splash device 2 or between the fender body 1 and the anti-splash device 2; An energy supply device, the energy supply device comprises a solar panel 4 and an energy storage battery 5, and the energy storage battery 5 is electrically connected to the solar panel 4 and the heating device 3 respectively; A fender bracket 6, wherein the fender bracket 6 is fixedly connected to the outer surface of the fender body 1; The detection device 7 is located on the fender bracket 6 or on the fender body 1 .

[0024] The present application uses solar panels 4 to collect solar energy to provide energy for the system without consuming additional energy of the entire vehicle. The detection device 7 automatically collects stress data and temperature data to determine the start and stop of the heating device 3 without manual operation. By deicing the fender, the load on the fender body 1 and the fender bracket 6 is reduced, and the reliability of the fender bracket 6 is increased.

[0025] The fender body 1 serves as the basic structure of the vehicle fender and is used to block splashing rain and mud.

[0026] The anti-splash device 2 is located on the inner side of the fender body 1, and can allow air to pass through, while absorbing the energy of the water spray and reducing the splash of water mist.

[0027] The heating device 3 is located inside the anti-splash device 2 or between the fender body 1 and the anti-splash device 2, and is used for heating the fender under low temperature conditions to prevent ice formation.

[0028] The energy supply device includes a solar panel 4 and an energy storage battery 5. The solar panel 4 is used to collect solar energy and convert it into electrical energy, and the energy storage battery 5 is used to store electrical energy and is electrically connected to the solar panel 4 and the heating device 3 respectively, to provide necessary energy for the entire system.

[0029] The fender support 6 is fixedly connected to the outer surface of the fender body 1 for supporting the fender.

[0030] The detection device 7 is located on the fender bracket 6 or on the fender body 1 and is used for automatically collecting stress data and temperature data.

[0031] When the detection device 7 detects that the stress on the fender exceeds a predetermined value or the temperature is below the freezing point, a signal is sent to the control system.

[0032] The control system determines whether to start the heating device 3 according to the received signal.

[0033] After the heating device 3 is started, the fender is heated by resistance heating or other means to prevent ice from forming.

[0034] The solar panel 4 is used to collect solar energy to provide energy for the system, which does not consume the vehicle's fuel or electricity, reduces energy consumption, and meets the requirements of energy conservation and emission reduction. The detection device 7 automatically collects data and controls the start and stop of the heating device 3 without manual intervention, which improves the convenience of use and the level of intelligence. By heating and deicing, the problem of overload of the fender body 1 and the fender bracket 6 caused by icing is reduced, and the driving safety of the vehicle in low temperature and rainy weather is improved. Damage to the fender and deformation of the bracket caused by icing are avoided, and the service life of the fender and its bracket is extended. It is suitable for various models and various severe weather conditions, especially in low temperature, rainy and snowy areas, and has good practical value.

[0035] In some embodiments of the present application, the detection device 7 includes a stress sensor, which is located on the fender bracket 6 and is signal-connected to the heating device 3 .

[0036] The stress sensor is located on the fender bracket 6 and can directly sense stress changes on the fender bracket 6 caused by icing or other reasons.

[0037] A signal connection is established between the stress sensor and the heating device 3 . When the stress sensor detects that the stress on the fender bracket 6 exceeds a preset safety threshold, it sends a signal to the heating device 3 .

[0038] The heating device 3 receiving the signal from the stress sensor will start the heating function to heat the fender to melt ice that may be formed and reduce the load on the fender bracket 6 .

[0039] The stress sensor continuously monitors the stress state of the fender bracket 6 and controls the start and stop of the heating device 3 according to the real-time data to keep the fender in a safe working state.

[0040] In some embodiments of the present application, the detection device 7 includes a temperature sensor, which is located on the fender bracket 6 or the fender body 1 , and the temperature sensor is signal-connected to the heating device 3 .

[0041] The temperature sensor may be located on the fender bracket 6 or on the fender body 1 so as to accurately detect the temperature change of the fender and its bracket.

[0042] A signal connection is established between the temperature sensor and the heating device 3 . When the temperature sensor detects that the ambient temperature is lower than a preset threshold, it sends a signal to the heating device 3 .

[0043] The heating device 3 receiving the temperature sensor signal will start the heating function to heat the fender to prevent ice from forming or melt the ice that has already formed.

[0044] The temperature sensor continuously monitors the ambient temperature and controls the start and stop of the heating device 3 according to the real-time data to ensure that the fender operates within a suitable temperature range.

[0045] In some embodiments of the present application, the heating device 3 includes a heating wire, the anti-splash device 2 has a cavity inside, and the heating wire spirally extends in the cavity.

[0046] The heating device 3 is composed of a heating wire, which is a resistance wire that can convert electrical energy into thermal energy.

[0047] The anti-splash device 2 is designed with a cavity inside, which provides space for the installation and heating of the heating wire.

[0048] The heating wire extends in a spiral shape in the cavity. This layout can maximize the heating area of ​​the heating wire and ensure even heat distribution.

[0049] When the temperature sensor detects that the fender temperature is lower than the preset threshold, the heating wire receives a start signal and starts heating. The heat generated by the heating wire is transferred to the entire fender through the cavity, thereby preventing ice from forming or melting ice that has already formed.

[0050] The spiral heating wire can provide uniform heat distribution, avoiding the problem of local overheating or insufficient heating. The heating wire is directly located inside the anti-splash device 2, with high heat transfer efficiency, and can quickly heat the fender.

[0051] In some embodiments of the present application, the heating device 3 includes a heating wire, and there is a gap between the anti-splash device 2 and the fender body 1, and the heating wire spirally extends in the gap.

[0052] The heating device 3 is composed of a heating wire, which can generate heat after being energized, and is used to heat the fender.

[0053] A gap is designed between the anti-splash device 2 and the fender body 1, and the gap provides space for the installation of the heating wire.

[0054] The heating wire is spirally extended in the gap, and this layout can ensure that the heat is evenly transferred to the fender body 1 and the anti-splash device 2.

[0055] When the temperature sensor detects that the temperature around the fender is lower than a certain threshold, the heating wire is powered on and starts to heat up. The heat is transferred to the fender body 1 through the spiral heating wire, thereby preventing ice from forming or melting the ice that has already formed.

[0056] The spiral heating wire evenly distributes heat in the gap, avoids local overheating, and improves heating efficiency. By installing the heating wire in the gap between the anti-splash device 2 and the fender body 1, no additional space is occupied, and the overall structure of the fender is kept compact.

[0057] In some embodiments of the present application, the fender body 1 is a plate-like structure with an arc-shaped cross-section.

[0058] The cross section of the fender body 1 is arc-shaped, and this design can effectively guide rainwater and mud to flow along the surface of the fender to reduce splashing.

[0059] The curved structure can utilize the principles of fluid dynamics, allowing water to slide smoothly along the curved surface when it contacts the fender instead of rebounding or splashing.

[0060] Arc structures usually have better mechanical properties than flat structures and can withstand greater external forces without being easily deformed.

[0061] The curved fenders can be designed according to the tire and wheel arc shapes of different models to provide better fit and protection.

[0062] In some embodiments of the present application, the surface of the anti-splash device 2 has a mesh structure or a honeycomb structure.

[0063] The surface of the anti-splash device 2 is designed to be mesh-like or honeycomb-like. This structure has many small holes or gaps, allowing air to pass through while being able to capture and block water mist and larger water drops.

[0064] Thanks to the holes in the structure, air can circulate freely, which helps to reduce air resistance in the fender area and maintain good aerodynamic properties.

[0065] When the vehicle is driving, rainwater and mud are thrown up by the tires, and the anti-splash device 2 can intercept these water mists to prevent them from splashing to other parts of the vehicle or the rear vehicle.

[0066] The intercepted water droplets flow out along the surface of the splash guard 2 under the action of gravity, thereby reducing the accumulation of ice on the fender.

[0067] In some embodiments of the present application, a battery device is further included. The battery device is located on the outer surface of the fender body 1 and is electrically connected to the heating device 3 .

[0068] The replaceable battery device is located on the outer surface of the fender body 1 and is electrically connected to the heating device 3. This layout is convenient for installation and removal.

[0069] Under normal circumstances, the solar panel 4 and the energy storage battery 5 are responsible for providing the necessary electrical energy for the heating device 3. When the solar panel 4 cannot generate enough electrical energy due to weather reasons (such as at night or on a cloudy day), the battery takes over the power supply as a backup energy source.

[0070] The control unit in the system monitors the output of the solar panel 4, the energy storage battery 5, and the power of the storage battery. Once it is detected that the output of the solar panel 4 is insufficient and the energy storage battery 5 is insufficient, the system will automatically switch to the storage battery for power supply.

[0071] The battery unit is designed as a replaceable module, and when the battery is exhausted or its performance deteriorates, the user can easily remove it and replace it with a new battery.

[0072] In the second aspect, the present application also provides a vehicle mudguard system, comprising a frame longitudinal beam, a wheel and a vehicle mudguard as described in any embodiment of the first aspect, wherein the mudguard body 1 in the vehicle mudguard is covered on the outer side of the wheel, and the mudguard bracket 6 is fixedly connected to the frame longitudinal beam.

[0073] In this embodiment, a solar panel 4 is installed on the fender to collect solar energy and store it in an energy storage battery 5; a heating wire is added inside the fender anti-splash device 2 to utilize the energy in the energy storage battery 5 for heating; a stress sensor and a temperature sensor are added to the fender bracket 6 to determine whether the heating device 3 is started or stopped.

[0074] The vehicle mud guard system comprises a frame longitudinal beam, a wheel and a vehicle mud guard. The mud guard body 1 is arranged on the outer side of the wheel, and the mud guard bracket 6 is fixedly connected to the frame longitudinal beam.

[0075] A solar panel 4 is mounted on the fender to collect solar energy and convert it into electrical energy.

[0076] The collected solar energy is stored in the energy storage battery 5 so as to be used when needed.

[0077] A heating wire is added inside the fender anti-splash device 2. When low temperature or icing conditions are detected, the energy in the energy storage battery 5 is used to heat the heating wire to melt the ice and snow.

[0078] A stress sensor and a temperature sensor are added to the fender bracket 6, and these sensors are used to monitor the stress and temperature changes of the fender.

[0079] The data collected by the stress sensor and the temperature sensor are transmitted to the control unit, and the control unit determines whether to start the heating device 3 based on the data. For example, when the temperature is lower than the set threshold and there is a risk of icing, the heating device 3 is automatically started.

[0080] In a third aspect, the present application further provides a method for controlling a vehicle fender, which is applied to the vehicle fender as described in any one embodiment of the first aspect, and comprises the following steps: The solar panel 4 absorbs solar energy and converts it into chemical energy which is stored in the energy storage battery 5; The detection device 7 detects the stress of the fender bracket 6 and the ambient temperature, and controls the start and stop of heating according to the changes in the ambient temperature and stress: When the ambient temperature is lower than the preset temperature first, and the detection stress gradually increases until it is greater than the first preset stress, heating is turned on; After heating is turned on, when the detected stress is less than the second preset stress, heating is stopped; When the ambient temperature is higher than the preset temperature first, and the detection stress gradually increases until it is greater than the first preset stress, heating is not started.

[0081] Normal state: the solar panel 4 absorbs solar energy and stores the energy in the energy storage battery 5.

[0082] Detection and information feedback: The stress sensor and the temperature sensor detect the stress of the fender bracket 6 and the ambient temperature, and control the start and pause of heating according to the changes in the ambient temperature and stress.

[0083] Heating start and stop judgment logic: The temperature is lower than 0℃ first, and the stress detected by the stress sensor gradually increases to 10kg, then heating is turned on. Heating is stopped when the stress detected by the stress sensor is less than 7kg.

[0084] The stress detected by the stress sensor gradually increases to 10kg, and then the temperature is lower than 0℃, which is judged as mud hanging and heating is not started.

[0085] In this embodiment, the space on the fender is used to install the solar panel 4, and the energy collected by the solar panel 4 is used to heat the fender anti-splash device 2 to melt the ice on the fender, so as to extend the service life of the fender bracket 6.

[0086] The ice condition on the fender is detected by temperature sensor and stress sensor, and the system is started and stopped automatically.

[0087] Compared with the prior art, the technical solution provided by this application has the following beneficial technical effects: The present application uses solar panels 4 to collect solar energy to provide energy for the system without consuming additional energy of the entire vehicle.
