Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a subframe, subframe assembly, control method, and related products. Background Technology

[0002] The power source for a vehicle's suspension system can be a fully active suspension oil pump or an electric motor. This power source can adjust the stiffness, height, and damping of the fully active suspension. When the power source operates at high power, it heats up rapidly. For range-extended or hybrid vehicles, the power source temperature will be even higher due to the heat radiation from the engine and exhaust pipe.

[0003] Currently, the power source can only be cooled by natural wind, which is a low-efficiency cooling method. It is difficult to lower the temperature of the power source. In order to protect the power source, it can only be operated at low power or even shut down. This will affect the performance of the suspension system and reduce the comfort and safety of the whole vehicle. Summary of the Invention

[0004] This application provides a subframe, subframe assembly, control method, and related products that can rapidly cool the power source to improve the overall vehicle comfort and safety.

[0005] The first aspect of this application provides a subframe, including: a support beam; the support beam is provided with an airflow channel, the airflow channel having a first air inlet and a first air outlet, the first air inlet being used to allow airflow provided by a fan to enter the airflow channel, and the first air outlet being used to provide airflow to the component to be cooled.

[0006] In this application, an airflow channel is installed on the subframe. This design is simple and effectively reduces the temperature of the components to be cooled, protecting them and ensuring their normal operation, thereby guaranteeing the vehicle's comfort and safety. Furthermore, the airflow channel does not occupy additional space, reducing the overall vehicle complexity. Using airflow to cool the components, compared to using liquid cooling, adds almost no weight to the vehicle.

[0007] In some possible implementations, the subframe also includes an exhaust pipe with an exhaust channel having a second air inlet and a second air outlet; the exhaust pipe is connected to a support beam, the second air inlet and the first air outlet are connected, and the second air outlet is used to provide airflow to the component to be cooled.

[0008] In the above implementation, there can be multiple exhaust pipes, and the second air inlets of the multiple exhaust pipes are respectively connected to multiple first air outlets, with the second air outlets of the multiple exhaust pipes all facing the component to be cooled. By setting up exhaust pipes, the airflow from the first air outlets is guided to a position closer to the component to be cooled, which can reduce the airflow loss rate and improve the heat dissipation efficiency.

[0009] In some possible implementations, the inner diameter of the exhaust channel gradually increases from the second air inlet to the second air outlet.

[0010] In the above implementation method, the air outlet channel is funnel-shaped, which allows the airflow to spread naturally in all directions when it is ejected, forming a wider air supply area and a more uniform airflow distribution.

[0011] In some possible implementations, the support beam is a hollow pipe, and the hollow cavity of the hollow pipe forms an airflow channel.

[0012] In the above implementation method, the hollow cavity of the support beam is directly used as an airflow channel, which can simplify the structure of the subframe and reduce its weight.

[0013] In some possible implementations, the outer wall surface and / or the inner wall surface of the support beam are provided with a first protective layer.

[0014] In the above implementation, after the airflow enters the airflow channel, it comes into contact with the inner wall of the support beam. The first protective layer protects the inner wall of the support beam, preventing it from being corroded and oxidized by prolonged airflow impact, thus extending the service life of the subframe and ensuring its structural strength and driving safety. The outer wall of the support beam is constantly exposed to harsh environments. During vehicle operation, the outer wall may come into contact with rainwater, snowmelt, mud, sand, or gravel. The first protective layer protects the outer wall of the support beam, preventing corrosion from acidic or alkaline substances carried by these foreign objects.

[0015] In some possible implementations, the support beam is a hollow tube, and the subframe also includes an internal tube, which is located in the hollow cavity of the hollow tube, and the airflow channel is located in the internal tube.

[0016] In the above implementation method, the support beam is the original structure of the subframe. By setting internal pipes in the support beam and setting the airflow channel in the internal pipes, it is not necessary to perform special treatments such as anti-corrosion and sealing on the support beam, nor is it necessary to re-mold the support beam. Only internal pipes need to be added in the support beam, which can increase the convenience of setting the airflow channel.

[0017] In some possible implementations, a second protective layer is provided on the outer wall surface of the internal pipe and / or the inner wall surface of the internal pipe.

[0018] In the above implementation, after the airflow enters the airflow channel, it comes into contact with the inner wall of the internal pipe. The second protective layer protects the inner wall of the internal pipe, preventing it from being corroded and oxidized by prolonged airflow impact. This extends the service life of the subframe and ensures its structural strength and driving safety. A second protective layer is also installed on the outer wall of the internal pipe to protect it from moisture and other corrosive agents, further extending its lifespan.

[0019] In some possible implementations, the subframe also includes a load-bearing section connected to the support beam, which is used to support the components to be cooled.

[0020] In the above implementation method, the component to be cooled can be supported by setting up a bearing part.

[0021] In some possible implementations, the support beam includes a first crossbeam, a second crossbeam, a first longitudinal beam, and a second longitudinal beam, which are connected end to end in sequence. A first air inlet is located on the first crossbeam, and a first air outlet is located on at least one of the first crossbeam, the second crossbeam, the first longitudinal beam, and the second longitudinal beam.

[0022] In the above implementation, the first crossbeam is located at the foremost side of the support beam, and the first air inlet is set on the first crossbeam, so that the airflow driven by the vehicle during driving can flow into the airflow channel in a forward direction, which can improve the cooling effect. The position of the first air outlet can be selected according to the position of the component to be cooled. The first air outlet can be set on at least one of the first crossbeam, the second crossbeam, the first longitudinal beam, and the second longitudinal beam, which provides a high degree of flexibility.

[0023] In some possible implementations, there are two airflow channels, namely a first airflow channel and a second airflow channel; the first air inlet of the first airflow channel and the first air inlet of the second airflow channel are both located on the first crossbeam; the first air outlet of the first airflow channel and the first air outlet of the second airflow channel are both located on the second crossbeam; at least a portion of the first airflow channel is located on the first longitudinal beam, and at least a portion of the second airflow channel is located on the second longitudinal beam.

[0024] In the above implementation, two airflow channels are provided to increase heat dissipation efficiency and enable the components to be cooled to cool down quickly. Both the first and second air outlets are equipped with second crossbeams, ensuring that the airflow direction within the airflow channels is the same as the surrounding airflow direction when the vehicle is moving forward. This utilizes the surrounding airflow to increase the speed and flow rate of the airflow within the airflow channels, thereby improving the heat dissipation effect.

[0025] In some possible implementations, the first airflow channel is disposed on the first longitudinal beam and the second transverse beam, and the second airflow channel is disposed on the second longitudinal beam and the second transverse beam.

[0026] In the above implementation method, two airflow channels are set up by making reasonable use of the four support sections of the support beam, so that the airflow direction of the two airflow channels is from the front to the rear of the vehicle, which can increase the heat dissipation effect.

[0027] In some possible implementations, the second crossbeam is equipped with an isolation element located between the first air outlet of the first airflow channel and the first air outlet of the second airflow channel.

[0028] In the above implementation, the airflow in the first airflow channel flows from left to right in the second crossbeam, and the airflow in the second airflow channel flows from right to right in the second crossbeam. By setting up the isolation component, turbulence can be avoided after the airflow in the first airflow channel and the airflow in the second airflow channel collide.

[0029] In some possible implementations, the connection points between the first crossbeam and the first longitudinal beam, the connection points between the first crossbeam and the second longitudinal beam, the connection points between the second crossbeam and the first longitudinal beam, and the connection points between the second crossbeam and the second longitudinal beam are all circular arc transitions.

[0030] In the above implementation, setting all four connection points to be arc-shaped can reduce airflow resistance, reduce energy loss, reduce airflow wear and impact on the inner wall of the airflow channel, reduce noise, and extend the service life of the airflow channel.

[0031] In some possible implementations, the subframe also includes an air intake pipe connected to the support beam. The air intake pipe includes an air intake channel with a third air inlet and a third air outlet. The third air outlet is connected to the first air inlet. The third air inlet is used to allow airflow provided by the fan to enter the airflow channel. The airflow in the airflow channel passes through the third air outlet and the first air inlet in sequence before entering the airflow channel.

[0032] In the above implementation method, by setting up an air intake pipe, gas can be guided into the airflow channel, increasing the airflow rate in the airflow channel and improving the heat dissipation effect.

[0033] The second aspect of this application provides a subframe assembly, including: a fan and a subframe according to any one of the first aspects of this application.

[0034] In the second aspect of this application, an airflow channel is provided on the subframe, and the airflow provided by the fan is then delivered to the component to be cooled through the airflow channel. This structure is simple and can efficiently reduce the temperature of the component to be cooled, protecting it and ensuring its normal operation, thereby ensuring the comfort and safety of the vehicle. Furthermore, the airflow channel does not occupy additional space, reducing the overall vehicle complexity. And compared to using liquid cooling, using airflow to cool the component adds almost no weight to the vehicle.

[0035] In some possible implementations, the subframe assembly also includes an exhaust pipe with an exhaust channel having a second air inlet and a second air outlet; the exhaust pipe is connected to a support beam, the second air inlet and the first air outlet are connected, and the second air outlet is used to provide airflow to the component to be cooled.

[0036] In some possible implementations, the subframe assembly also includes a first filter screen located within the air outlet passage.

[0037] In the above implementation, the first filter screen can prevent impurities from entering the airflow channel from the air outlet channel, thus avoiding blockage or contamination of the airflow channel.

[0038] In some possible implementations, the subframe assembly also includes an intake pipe and a mounting pipe. The intake pipe is connected to the support beam and includes an intake channel with a third intake port and a third exhaust port. The mounting pipe is connected to the intake pipe and includes a mounting channel with an inner diameter larger than that of the intake channel. The mounting channel has a fourth intake port and a fourth exhaust port. The third intake port and the fourth exhaust port are connected, and the third exhaust port is connected to the first intake port. A fan is disposed within the mounting channel.

[0039] In the above implementation method, the mounting tube can facilitate the installation of the fan and also protect the fan.

[0040] In some possible implementations, the inner diameter of the fourth air inlet is larger than the inner diameter of the fourth air outlet. Optionally, the inner diameter of the mounting channel gradually changes, decreasing from the fourth air inlet to the fourth air outlet. Optionally, the inner diameter of a portion of the mounting channel gradually decreases, while the inner diameter of another portion remains unchanged.

[0041] In the above implementation, at least part of the installation channel can be funnel-shaped, which can reduce the intake resistance of the fourth air intake, improve intake efficiency, and increase intake uniformity.

[0042] In some possible implementations, the subframe assembly also includes a second filter screen, which is disposed within the mounting channel and faces the air intake side of the fan.

[0043] In the above implementation, the second filter can prevent impurities from entering the airflow channel to avoid blockage or contamination of the airflow channel, and can prevent foreign objects from affecting the operation of the fan.

[0044] In some possible implementations, the support beam is a hollow pipe, and the hollow cavity of the hollow pipe forms an airflow channel; the support beam is provided with process holes, and the subframe assembly also includes a sealing plug, which is located in the process hole.

[0045] In the above implementation, the sealing plug can be inserted into the process hole to seal the process hole and prevent airflow from flowing out of the process hole.

[0046] A third aspect of this application provides a control method applied to a subframe, subframe assembly, or vehicle, wherein the subframe, subframe assembly, or vehicle includes a support beam; the support beam is provided with an airflow channel, the airflow channel having a first air inlet and a first air outlet, the first air inlet being used to allow airflow provided by a fan to enter the airflow channel, and the first air outlet being used to provide airflow to the component to be cooled; the control method includes: Obtain first information, which includes temperature information of the component to be cooled, and / or, status information of the vehicle's air intake grille; Based on the first information, a control signal is generated. The control signal is used to control the state of the fan so that the fan can blow airflow through the airflow channel to the part to be cooled.

[0047] In the third aspect of this application, by setting an airflow channel on the subframe, when the temperature of the component to be cooled is too high, the airflow provided by the fan is sent to the component to be cooled through the airflow channel, which can reduce the temperature of the component to be cooled, so that the component to be cooled can work normally, thereby improving the comfort and safety of the vehicle.

[0048] In some possible implementations, the control signal includes a first control signal; generating the control signal based on the first information includes: generating the first control signal when the first information indicates that the temperature of the component to be cooled is greater than or equal to a first threshold, the first control signal being used to control the fan to be in a working state.

[0049] In the above implementation, the fan is only turned on when the temperature of the component to be cooled is higher than the first threshold, which can save energy.

[0050] In some possible implementations, the power of the fan during operation is positively correlated with the temperature of the component being cooled.

[0051] In the above implementation, the fan can be a continuously variable speed fan. When the temperature of the component to be cooled is higher than the first threshold, the fan speed can increase as the temperature of the component to be cooled increases, and the fan speed can decrease as the temperature of the component to be cooled decreases, so as to save energy while reducing the temperature of the component to be cooled.

[0052] In some possible implementations, the first control signal is also used to indicate information about the fan's operating state, which includes at least a first operating state and a second operating state, with the fan's power in the first operating state being different from that in the second operating state.

[0053] In the above implementation, the power in the first operating state can be less than the power in the second operating state. The fan can include a first speed and a second speed, where the first operating state can be the fan at speed one, and the second operating state can be the fan at speed two. When the temperature of the component to be cooled is higher than a first threshold but lower than a third threshold, the fan can be turned on at speed one; when the temperature of the component to be cooled is higher than the third threshold, the fan can be turned on at speed two. The third threshold is greater than the first threshold, for example, the third threshold can be 120 degrees Celsius. The higher the temperature of the component to be cooled, the higher the fan speed, the higher the power, so as to quickly reduce the temperature of the component to be cooled. After the temperature of the component to be cooled decreases, the fan speed can be reduced, and the corresponding fan speed and power decrease, which can save energy and further reduce the temperature of the component to be cooled.

[0054] In some possible implementations, the first control signal is also used to control the air intake grille to be in the open state.

[0055] In the above implementation, when the temperature of the component to be cooled exceeds a first threshold, the fan starts and simultaneously the air intake grille is opened, allowing outside air to enter the mounting channel. The airflow is then blown by the fan within the mounting channel into the air intake passage, and from there into the airflow channel, ultimately reaching the component to be cooled. With the air intake grille open, airflow during vehicle operation can naturally enter the mounting channel, increasing airflow velocity and volume, and improving heat dissipation efficiency.

[0056] In some possible implementations, the control signal includes a second control signal; generating the control signal based on the first information includes: generating the second control signal when the temperature of the component to be cooled, as indicated by the first information, is less than a second threshold, the second control signal being used to control the fan to be in a closed state, and / or to control the air intake grille to be in a closed state.

[0057] In the above implementation, when the fan is off, it indicates that the temperature of the component to be cooled has dropped to a safe range. At this point, the air intake grille can be closed simultaneously to prevent foreign objects from entering. That is, when the temperature of the component to be cooled is too high, both the fan and the air intake grille are open; when the temperature of the component to be cooled is normal, both the fan and the air intake grille are closed. Determining the fan's state based first on the temperature of the component to be cooled, and then determining the air intake grille's state based on the fan's state, allows for efficient cooling of the component while conserving resources.

[0058] Alternatively, the closure of the air intake grille can be independent of the fan's synchronization. With the fan off, the grille's closure can be determined by the engine temperature. When the engine temperature is too high, the grille can be opened to allow natural airflow into the engine compartment to cool the engine. When the engine temperature is normal, the grille can be closed to prevent foreign objects from entering the engine compartment.

[0059] In some possible implementations, the control signal includes a first control signal; the first control signal is generated when the first information indicates that the air intake grille is in the open state, and the first control signal is used to control the fan to be in the working state.

[0060] In the above implementation, the open air intake grille indicates that the engine temperature is too high. Since the component to be cooled is in the same space as the engine, the heat emitted by the engine may affect the component, causing it to overheat. In this case, the fan can be turned on to cool the component.

[0061] In some possible implementations, the control signal may also include a second control signal; the control method may also include generating a second control signal when the air intake grille switches from an open state to a closed state, the second control signal being used to control the fan to be in a closed state.

[0062] In the above implementation, when the air intake grille is closed, it indicates that the engine temperature has returned to normal, and the heat emitted by the engine will no longer affect the components being cooled. At this time, the fan can also be turned off to save resources. Determining the fan status based on the air intake grille's position can both prevent the components being cooled from overheating and conserve resources.

[0063] In some possible implementations, a second control signal is generated when the air intake grille switches from an open state to a closed state, including: generating a second control signal when the air intake grille switches from an open state to a closed state and the temperature of the component to be cooled is less than a second threshold.

[0064] In the above implementation, the air intake grille is closed and the temperature of the component to be cooled is within the normal range. At this time, the fan is turned off to save resources.

[0065] Among some possible implementations, the control method also includes: controlling the fan to operate when the air intake grille switches from an open state to a closed state and the temperature of the component to be cooled is greater than or equal to a first threshold.

[0066] In the above implementation, although the air intake grille is closed, the temperature of the component to be cooled is still too high. At this time, the control fan is turned on to cool the component.

[0093] The embodiments of this application are described below with reference to the accompanying drawings.

[0094] The use of prefixes such as "first" and "second" in this scheme is solely for distinguishing different descriptive objects and does not limit the position, order, priority, quantity, or content of the described objects. For example, the described object is not limited by the prefix and can be one or more; taking "first device" as an example, "device" can be one or more. Furthermore, the objects modified by different prefixes can be the same or different. For example, if the described object is "device," then "first device" and "second device" can be the same device, the same type of device, or different types of devices. In summary, the use of prefixes to distinguish descriptive objects in this application does not constitute a limitation on the described objects. The description of the described objects is given in the claims or the context of the embodiments, and the use of such prefixes should not constitute unnecessary restrictions.

[0095] refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 2000 provided in an embodiment of this application. This application provides a vehicle 2000, which is a vehicle in a broad sense, including transportation vehicles (such as commercial vehicles, passenger cars, motorcycles, flying cars, trains, etc.), industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), agricultural equipment (such as lawnmowers, harvesters, etc.). Furthermore, the robot can be an automated guided vehicle (AGV), a walking conversational robot, or a service robot.

[0096] For ease of description, we define the length direction of vehicle 2000 as the X-axis, the width direction as the Y-axis, and the thickness direction as the Z-axis. The X-axis, Y-axis, and Z-axis are all perpendicular to each other.

[0097] It should be noted that the directional terms such as "top," "bottom," "left," "right," "front," and "rear" used in the description of vehicle 2000 in this application are mainly based on the vehicle 2000 as described in the attached document. Figure 1 The orientation shown in the diagram is described as follows: "top" or "up" is the positive direction of the Z-axis, "bottom" or "down" is the negative direction of the Z-axis, "right" is the positive direction of the Y-axis, "left" is the negative direction of the Y-axis, "rear" is the negative direction of the X-axis, and "front" is the positive direction of the X-axis. This does not constitute a limitation on the orientation of the vehicle 2000 in actual application scenarios.

[0098] refer to Figure 2 , Figure 2 This is a schematic diagram of the subframe assembly 1000, air intake grille 400, and cooling component 300 of a vehicle 2000 provided in this embodiment of the application. The vehicle 2000 includes the subframe assembly 1000, the cooling component 300, and the air intake grille 400.

[0099] The subframe assembly 1000 is the connecting bridge between the suspension system and the body of the vehicle 2000, and is also one of the core load-bearing components of the chassis. The subframe assembly 1000 is located at the bottom of the front side of the vehicle 2000 and is used to support the engine, transmission and cooling components 300, etc.

[0100] The grille 400 is typically mounted on the front of the vehicle, above the front bumper, directly opposite the engine compartment. When the engine is at a normal operating temperature, the grille 400 is closed. When the engine overheats, the grille 400 can open to allow airflow into the engine compartment to cool it.

[0101] The cooling component 300 can be mounted on the subframe assembly 1000. The cooling component 300 can serve as the power source for the fully active suspension system, which can be a fully active suspension oil pump and / or a motor. The fully active suspension oil pump can adjust the oil pressure and flow rate in real time according to the vehicle's posture and road conditions to achieve dynamic suspension response. The fully active suspension oil pump can pressurize the low-pressure oil in the reservoir into high-pressure oil, and then deliver the high-pressure oil to the working chamber of the suspension shock absorber, pushing the shock absorber piston to rise and fall rapidly, actively adjusting the suspension travel, offsetting road bumps, suppressing body roll, pitch, and bounce, and improving the comfort of the driver and passengers.

[0102] The torque output by the motor is converted into the linear motion of the shock absorber piston through the transmission mechanism, which can quickly adjust the suspension travel, offset road bumps, suppress body roll, pitch and bounce, and improve the comfort of the driver and passengers.

[0103] refer to Figure 2 , Figure 3 and Figure 4 , Figure 3 This is a structural schematic diagram from another perspective of the subframe assembly 1000, air intake grille 400, and cooling component 300 of the vehicle 2000 provided in this embodiment of the application. Figure 4 for Figure 2 The accompanying drawings show a cross-sectional view. The subframe assembly 1000 provided in this embodiment includes a subframe 100 and a fan 200. The subframe 100 provided in this embodiment includes a support beam 10; the support beam 10 is provided with an airflow channel 11, the airflow channel 11 having a first air inlet 12 and a first air outlet 13, the first air inlet 12 for allowing airflow provided by the fan 200 to enter the airflow channel 11, and the first air outlet 13 for providing airflow to the component 300 to be cooled.

[0104] For example, there can be multiple first air outlets 13, which are arranged sequentially at intervals along the length of the support beam 10. The arrangement of multiple first air outlets 13 allows the airflow to be concentrated at the multiple first air outlets 13 from filling the entire airflow channel 11, which can increase the airflow velocity and make the airflow blow towards the part to be cooled 300 at high speed, so as to quickly cool the part to be cooled 300. Alternatively, the first air outlet 13 can be an elongated hole.

[0105] For example, the fan 200 can be disposed at the first air inlet 12, with the air inlet side of the fan 200 communicating with the outside air and the air outlet side of the fan 200 facing the first air inlet 12. When the temperature of the component 300 to be cooled is too high, the fan 200 can be operated. The airflow provided by the fan 200 can enter the airflow channel 11 from the first air inlet 12, then flow out of the airflow channel 11 from the first air outlet 13, and blow towards the component 300 to cool it down.

[0106] For example, when the component to be cooled 300 is a fully active suspension oil pump, the fully active suspension oil pump includes a controller and a drive motor, with the drive motor facing the first air outlet 13 and the controller located above the drive motor. Alternatively, the controller can also be positioned opposite the first air outlet 13, with the drive motor located above the controller. The fully active suspension oil pump also includes a pump body and gears, etc., and the main body can also be positioned opposite the first air outlet 13; this application is not limited to these components.

[0107] In this embodiment, an airflow channel 11 is provided on the subframe 100. This simple structure effectively reduces the temperature of the component 300 to be cooled, protecting it and ensuring its normal operation, thereby guaranteeing the comfort and safety of the vehicle 2000. Furthermore, the airflow channel 11 does not occupy additional space, reducing the overall vehicle complexity. Moreover, using airflow to cool the component 300 adds almost no weight to the vehicle compared to using liquid cooling.

[0108] In some possible embodiments, when the fan 200 is turned on, the air intake grille 400 can be opened synchronously to allow airflow to enter the fan 200 from the air intake grille 400 and then enter the airflow channel 11 from the fan 200, thereby increasing the cooling effect. Alternatively, the air intake grille 400 may not be synchronized with the state of the fan 200.

[0109] In some possible embodiments, reference is made to Figure 4The subframe assembly 1000 also includes an exhaust pipe 20, which has an exhaust channel 21. The exhaust channel 21 has a second air inlet 22 and a second air outlet 23. The exhaust pipe 20 is connected to the support beam 10. The second air inlet 22 and the first air outlet 13 are connected. The second air outlet 23 is used to provide airflow to the component 300 to be cooled.

[0110] For example, the air outlet pipe 20 can be integrally formed with the support beam 10, in which case the air outlet pipe 20 is part of the subframe 100. Alternatively, the air outlet pipe 20 and the support beam 10 can be formed separately, and then the air outlet pipe 20 can be connected to the support beam 10.

[0111] For example, there can be multiple air outlet pipes 20, and the second air inlets 22 of the multiple air outlet pipes 20 are respectively connected to multiple first air outlets 13, and the second air outlets 23 of the multiple air outlet pipes 20 are all facing the component 300 to be cooled.

[0112] In this embodiment, by setting an air outlet pipe 20, the airflow from the first air outlet 13 is guided to a position closer to the component to be cooled 300, which can reduce the airflow loss rate and improve the heat dissipation efficiency.

[0113] In some possible embodiments, reference is made to Figure 5 , Figure 5 This is a partial structural diagram of the subframe assembly 1000 of the vehicle 2000 provided in this application embodiment. The subframe assembly 1000 also includes a first filter 80, which is disposed within the air outlet passage 21. The first filter 80 can prevent impurities from entering the airflow passage 11 from the air outlet passage 21, thus avoiding blockage or contamination of the airflow passage 11.

[0114] In some possible embodiments, a guide vane may be provided at the second air outlet 23, and the guide vane is rotatably connected to the air outlet pipe 20.

[0115] In this embodiment, when the air guide plate rotates, the direction of the airflow can be adjusted so that the airflow can blow onto more areas of the component 300 to be cooled, thereby improving the heat dissipation efficiency and enabling the component 300 to cool down quickly.

[0116] In some possible embodiments, reference is made to Figure 4 From the second air inlet 22 to the second air outlet 23, the inner diameter of the air outlet channel 21 gradually increases. That is, the air outlet channel 21 is funnel-shaped, which allows the airflow to naturally diffuse in all directions when it is ejected, forming a wider air supply area and a more uniform airflow distribution.

[0117] In some possible embodiments, reference is made to Figure 2 , Figure 3 and Figure 4The subframe assembly 1000 also includes an intake pipe 60 connected to the support beam 10. The intake pipe 60 includes an intake channel 61, which has a third intake port 62 and a third exhaust port 63. The third exhaust port 63 is connected to the first intake port 12. The third intake port 62 is used to allow the airflow provided by the fan 200 to enter the airflow channel 11. The airflow in the airflow channel 11 passes through the third exhaust port 63 and the first intake port 12 in sequence before entering the airflow channel 11.

[0118] For example, the intake pipe 60 can be integrally formed with the support beam 10, in which case the intake pipe 60 is part of the subframe 100. Alternatively, the intake pipe 60 can be machined separately and then connected to the support beam 10.

[0119] In this embodiment, by setting the air intake pipe 60, gas can be guided into the airflow channel 11, increasing the airflow rate in the airflow channel 11 and improving the heat dissipation effect.

[0120] In some possible embodiments, reference is made to Figure 4 The subframe assembly 1000 also includes a mounting tube 70 connected to the intake pipe 60. The mounting tube 70 includes a mounting channel 71, the inner diameter of which is larger than the inner diameter of the intake pipe 61. The mounting channel 71 has a fourth air inlet 72 and a fourth air outlet 73. The third air inlet 62 and the fourth air outlet 73 are connected, and the third air outlet 63 is connected to the first air inlet 12. A fan 200 is disposed within the mounting channel 71. Alternatively, the fan 200 can also be mounted within the intake pipe 61.

[0121] Optionally, the fourth air intake 72 is opposite to the air intake grille 400. When the air intake grille 400 is open, the airflow can enter the installation channel 71 without turning or passing through other components, which can reduce the airflow loss rate and increase the heat dissipation efficiency.

[0122] In this embodiment, the mounting tube 70 facilitates the installation of the fan 200 and also protects the fan 200. The mounting tube 70 can be machined separately. After the fan 200 is installed in the mounting channel 71 of the mounting tube 70, the mounting tube 70 is then connected to the air intake pipe 60. The mounting tube 70 and the air intake pipe 60 can be connected by welding, threaded connection, or snap-fit ​​connection. The fan 200 can be assembled into the mounting tube 70 by interference fit or threaded connection.

[0123] In some possible embodiments, reference is made to Figure 4The inner diameter of the fourth air inlet 72 is larger than the inner diameter of the fourth air outlet 73. Exemplarily, the mounting channel 71 includes a fixedly connected mounting section 74 and an outer diameter changing section 75. The mounting channel 71 extends through the mounting section 74 and the outer diameter changing section 75. The fourth air inlet 72 is located at the end of the outer diameter changing section 75 away from the mounting section 74, and the fourth air outlet 73 is located at the end of the mounting section 74 away from the outer diameter changing section 75. The inner diameter of the portion of the mounting channel 71 located in the mounting section 74 remains constant. The outer diameter of the mounting section 74 is the same as the outer diameter of the intake pipe 60, and the inner diameter of the portion of the mounting channel 71 located in the mounting section 74 is the same as the inner diameter of the intake channel 61. The inner diameter of the portion of the mounting channel 71 located in the outer diameter changing section 75 gradually changes, i.e., the outer diameter changing section 75 is trumpet-shaped. The mounting section 74 facilitates installation on the fan 200, and the outer diameter changing section 75 facilitates improved intake efficiency.

[0124] Alternatively, the inner diameter of the mounting channel 71 gradually changes, decreasing from the fourth air inlet 72 to the fourth air outlet 73. That is, the mounting channel 71 is funnel-shaped, which can reduce the air intake resistance of the fourth air inlet 72, improve air intake efficiency, and increase air intake uniformity.

[0125] In some possible embodiments, reference is made to Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of another part of the subframe assembly 1000 of the vehicle 2000 provided in the embodiments of this application. Figure 7 for Figure 6 The attached diagram shows a schematic diagram of the split structure. The subframe assembly 1000 also includes a second filter 90, which is disposed within the mounting channel 71 and faces the air intake side of the fan 200. In this embodiment, the second filter 90 can prevent impurities from entering the airflow channel 11 to avoid blockage or contamination of the airflow channel 11, and can also prevent foreign objects from affecting the operation of the fan 200.

[0126] In some possible embodiments, reference is made to Figure 2 and Figure 3 The subframe 100 also includes a support portion 105, which is located within the space enclosed by the support beams 10 and connected to the support beams 10. The support portion 105 is used to support the component 300 to be cooled. Exemplarily, the support portion 105 can be integrally formed with the support beams 10. Alternatively, the support portion 105 can be formed separately and then connected to the support beams 10. In this embodiment, by providing the support portion 105, the component 300 to be cooled can be supported.

[0127] In some possible embodiments, reference is made to Figure 2 , Figure 3 and Figure 4The support beam 10 comprises multiple support segments, which are connected end-to-end to form a closed-shape frame. The cross-section of each support segment can be a regular shape such as a circle, rectangle, ellipse, triangle, trapezoid, or parallelogram, or it can be an irregular shape. The support beam 10 can be manufactured using at least one of the following processes: stamping, welding, hydroforming, or casting. Its material can be steel or aluminum alloy. It has a hollow internal structure, which can be used to create airflow channels 11.

[0128] For example, the support beam 10 is a quadrilateral frame, that is, the support beam 10 includes four support segments. The four support segments of the support beam 10 are a first crossbeam 101, a second crossbeam 102, a first longitudinal beam 103, and a second longitudinal beam 104, which are connected end to end. Taking the first crossbeam 101 as an example, the cross section of the first crossbeam 101 refers to the cross section of the first crossbeam 101 when it is cut open by the plane formed by the X-axis and Z-axis directions.

[0129] For example, the structure of the subframe 100 in the figure is only schematic. In reality, the subframe 100 may include more components than those shown in the figure. For example, the subframe 100 may also include at least one connecting part (not shown), which can be used to connect with components such as the main frame, body, and engine. The connecting part may be a rod-like member with its two ends connected to the first longitudinal beam 103 and the second longitudinal beam 104, respectively. The connecting part may also be two clamps disposed at the connection point of two adjacent support sections, with the two clamps spaced apart and opposite each other, and the space between the two clamps can be used to connect other components.

[0130] For example, a first air inlet 12 is disposed on a first crossbeam 101, and a first air outlet 13 is disposed on at least one of the first crossbeam 101, a second crossbeam 102, a first longitudinal beam 103, and a second longitudinal beam 104. The first crossbeam 101, the second crossbeam 102, the first longitudinal beam 103, and the second longitudinal beam 104 can be integrally formed, or they can be formed separately and then assembled together. Alternatively, the first crossbeam 101, the first longitudinal beam 103, and the second longitudinal beam 104 can be integrally formed, and the second crossbeam 102 can be processed separately and then assembled onto the first longitudinal beam 103 and the second longitudinal beam 104.

[0131] For example, the first crossbeam 101 is located at the foremost side of the support beam 10, and the first air inlet 12 is set on the first crossbeam 101, so that the airflow driven by the vehicle 2000 when it is driving can flow into the airflow channel 11 in the direction, which can improve the cooling effect.

[0132] The positions of the first air outlet 13 and the support portion 105 need to be determined based on the position of the component 300 to be cooled. For example, if the component 300 to be cooled is located in the rear half of the subframe 100, the support portion 105 can be located at the rear end of the first longitudinal beam 103 and the second longitudinal beam 104, and the second air outlet 23 can be located on the second crossbeam 102. The thickness of the second crossbeam 102 along the Z-axis is less than the thickness of the first longitudinal beam 103 and the second longitudinal beam 104 along the Z-axis. The component 300 to be cooled can be located directly above the second crossbeam 102, and there is a gap between the component 300 to be cooled and the second crossbeam 102. The two ends of the component 300 along the Y-axis are respectively connected to the support portions 105 on the first longitudinal beam 103 and the second longitudinal beam 104. For example, two brackets can be provided on both sides of the component 300 along the Y-axis, and the two brackets are fixedly connected to the two support portions 105 respectively.

[0133] Alternatively, if the component to be cooled 300 is located in the left half of the subframe 100, the support portion 105 can be located at the left end of the first crossbeam 101 and the second crossbeam 102. The second air outlet 23 is located on the first longitudinal beam 103. If the component to be cooled 300 is located in the right half of the subframe 100, the support portion 105 can be located at the right end of the first crossbeam 101 and the second crossbeam 102, and the second air outlet 23 is located on the second longitudinal beam 104. If the component to be cooled 300 is located in the front half of the subframe 100, the support portion 105 is located at the front end of the first longitudinal beam 103 and the second longitudinal beam 104, and the first air outlet 13 is located on the first crossbeam 101.

[0134] In some possible embodiments, reference is made to Figure 2 and Figure 3 There are two airflow channels 11, namely a first airflow channel 11a and a second airflow channel 11b. The first air inlet 12 of the first airflow channel 11a and the first air inlet 12 of the second airflow channel 11b are both located on the first crossbeam 101. The first air outlet 13 of the first airflow channel 11a and the first air outlet 13 of the second airflow channel 11b are both located on the second crossbeam 102. At least a portion of the first airflow channel 11a is located on the first longitudinal beam 103, and at least a portion of the second airflow channel 11b is located on the second longitudinal beam 104. The number of airflow channels 11 can also be one, three, four, or five, etc.

[0135] For example, each airflow channel 11 can be matched with one first air inlet 12 or multiple first air inlets 12. For instance, an airflow channel 11 can be matched with two, three or four equal numbers of first air inlets 12.

[0136] For example, a first air inlet 12 can be matched with one airflow channel 11, or a first air inlet 12 can be matched with multiple airflow channels 11. For example, a first air inlet 12 can be matched with two, three or four equal numbers of airflow channels 11.

[0137] In this embodiment, two airflow channels 11 are provided to increase heat dissipation efficiency and enable the component to be cooled 300 to cool down quickly. Furthermore, both the first air outlet 13 and the second air outlet 23 are equipped with a second crossbeam 102, ensuring that the airflow direction within the airflow channel 11 is the same as the surrounding airflow direction when the vehicle 2000 is moving forward. The airflow channel 11 extends essentially from the front to the rear of the vehicle 2000, forming a continuous airflow path. This utilizes the surrounding airflow when the vehicle 2000 is moving to increase the speed and flow rate of the airflow within the airflow channel 11, thereby improving the heat dissipation effect.

[0138] In some possible embodiments, reference is made to Figure 2 and Figure 3 The first airflow channel 11a is disposed on the first longitudinal beam 103 and the second crossbeam 102, and the second airflow channel 11b is disposed on the second longitudinal beam 104 and the second crossbeam 102. In this embodiment, two airflow channels 11 are set up by making reasonable use of the four support sections of the support beam 10, so that the airflow direction of the two airflow channels 11 is from the front to the rear of the vehicle 2000, which can increase the heat dissipation effect. The support sections can be straight or curved. For example, the first crossbeam 101 and the second crossbeam 102 both extend along the Y-axis and are both straight, while the first longitudinal beam 103 and the second longitudinal beam 104 both extend along the X-axis and are curved.

[0139] The above description uses the support beam 10 as a closed shape as an example. Alternatively, the support beam 10 can also be a non-closed pattern formed by connecting multiple support segments in sequence. For example, the support beam 10 can be U-shaped, and the support beam 10 can only include the first crossbeam 101, the first longitudinal beam 103, and the second longitudinal beam 104. In this case, the first air outlet 13 can be set on the first longitudinal beam 103 and / or the second longitudinal beam 104.

[0140] In some possible embodiments, reference is made to Figure 8 , Figure 8 for Figure 5 The accompanying drawing shows a cross-sectional view. A spacer 50 is provided inside the second crossbeam 102, and the spacer 50 is located between the first air outlet 13 of the first airflow channel 11a and the first air outlet 13 of the second airflow channel 11b.

[0141] In this embodiment, the airflow in the first airflow channel 11a flows from left to right in the second crossbeam 102, and the airflow in the second airflow channel 11b flows from right to right in the second crossbeam 102. The isolation member 50 is provided to prevent turbulence from occurring after the airflow in the first airflow channel 11a and the airflow in the second airflow channel 11b collide.

[0142] In some possible embodiments, reference is made to Figure 2 and Figure 3 The connection points of the first horizontal beam 101 and the first vertical beam 103, the connection points of the first horizontal beam 101 and the second vertical beam 104, the connection points of the second horizontal beam 102 and the first vertical beam 103, and the connection points of the second horizontal beam 102 and the second vertical beam 104 are all rounded.

[0143] The connections between the first horizontal beam 101 and the first vertical beam 103, the first horizontal beam 101 and the second vertical beam 104, the second horizontal beam 102 and the first vertical beam 103, and the second horizontal beam 102 and the second vertical beam 104 are all arc-shaped.

[0144] In this embodiment, all four connection points are set in an arc shape, which can reduce airflow resistance, reduce energy loss, reduce the wear and impact of airflow on the inner wall of the airflow channel 11, reduce noise, and extend the service life of the airflow channel 11.

[0145] In some possible embodiments, reference is made to Figure 4 The support beam 10 is a hollow pipe, and the hollow cavity of the hollow pipe forms an airflow channel 11. By directly utilizing the hollow structure of the support beam 10 as the airflow channel 11, the structure of the subframe 100 can be simplified and the weight of the subframe 100 can be reduced.

[0146] For example, when machining the support beam 10, the support beam 10 will have some process holes 32, including positioning holes, assembly holes, and inspection holes, etc. In some possible embodiments, refer to... Figure 4 The subframe assembly 1000 may also include a sealing plug 33, which can be inserted into the process hole 32 to seal the process hole 32, prevent airflow from leaking from the process hole 32, and ensure the airtightness and functionality of the entire airflow channel 11.

[0147] In some possible embodiments, reference is made to Figure 4 The outer wall surface and / or the inner wall surface of the support beam 10 are provided with a first protective layer 31. For example, the first protective layer 31 may be a polyurethane coating or an epoxy resin coating, etc.

[0148] In this embodiment, after the airflow enters the airflow channel 11, it comes into contact with the inner wall of the support beam 10. The first protective layer 31 can protect the inner wall of the support beam 10, preventing the support beam 10 from being corroded and oxidized by the airflow impact over a long period of time. This can extend the service life of the subframe 100 and ensure the structural strength and driving safety of the subframe 100. The outer wall of the support beam 10 is exposed to harsh environments for a long time. During the driving of the vehicle 2000, the outer wall of the support beam 10 may come into contact with foreign objects such as rainwater, snow water, mud, sand, or gravel. The first protective layer 31 includes protecting the outer wall of the support beam 10 to prevent the support beam 10 from being corroded by acidic or alkaline substances carried by foreign objects.

[0149] In other possible embodiments, reference is made to Figure 9 and Figure 10 , Figure 9 This is a structural schematic diagram of the cooling component 300 and another subframe assembly 1000 of the vehicle 2000 provided in this embodiment of the application. Figure 10 for Figure 9 The diagram shows a cross-sectional view of the subframe assembly 1000. The support beam 10 is a hollow duct. The subframe also includes an internal duct 40. The support beam 10 is fitted within the internal duct 40, which is located within the hollow cavity of the support beam 10. An airflow channel 11 is located within the internal duct 40. When the airflow channel 11 is located within the internal duct 40, the exhaust pipe 20 needs to pass through the support beam 10 before connecting to the internal duct 40.

[0150] In this embodiment, the support beam 10 is the original structure of the subframe 100. By setting an internal pipe 40 inside the support beam 10 and setting the airflow channel 11 inside the internal pipe 40, it is not necessary to perform special treatments such as anti-corrosion and sealing on the support beam 10, nor is it necessary to re-mold the support beam 10. It is only necessary to add an internal pipe 40 inside the support beam 10, which can increase the convenience of setting the airflow channel 11.

[0151] For example, the outer wall surface of the internal pipe 40 and / or the inner wall surface of the internal pipe 40 are provided with a second protective layer 41. The second protective layer 41 may be a polyurethane coating or an epoxy resin coating, etc.

[0152] After the airflow enters the airflow channel 11, it comes into contact with the inner wall of the internal pipe 40. The second protective layer 41 protects the inner wall of the internal pipe 40, preventing it from being corroded and oxidized by prolonged airflow impact. This extends the service life of the subframe 100 and ensures its structural strength and driving safety. A second protective layer 41 is also provided on the outer wall of the internal pipe 40 to protect it from moisture and other corrosive agents, further extending its lifespan.

[0153] refer to Figure 11 , Figure 11A flowchart of a control method provided in an embodiment of this application. This application also provides a control method applied to the aforementioned subframe, subframe assembly, or vehicle. The subframe, subframe assembly, or vehicle all include a support beam. The support beam has an airflow channel with a first air inlet and a first air outlet. The first air inlet allows airflow provided by a fan to enter the airflow channel, and the first air outlet provides airflow to the component to be cooled. The control method includes: S11: Obtain first information. The first information includes the temperature information of the component to be cooled, and / or the status information of the vehicle's air intake grille. The status of the air intake grille includes an open state and / or a closed state.

[0154] S12: Based on the first information, generate a control signal. The control signal is used to control the state of the fan so that the fan can blow airflow through the airflow channel to the component to be cooled. The state of the fan includes an on state and / or an off state.

[0155] Both steps S11 and S12 can be executed by the control device. That is, the control device acquires the first information and generates a control signal based on the first information.

[0156] The control device in this application embodiment can be a device equipped with a processor / chip that can execute computer execution instructions, or it can be a processor / chip that can execute computer execution instructions. Optionally, the control device can be an electronic device, or it can be a processor / chip within an electronic device. Optionally, the control device can also be a computing device in a vehicle, or a software tool and / or hardware module in a computing device that can be used for drive control. For example, the control device can be a controller in a vehicle, which can include an advanced driving assistance system (ADAS) and / or an autonomous driving system (ADS), or a mobile data center (MDC) (or autonomous driving domain controller), a domain controller (DC), an electronic control unit (ECU), etc., wherein the DC, such as a motion domain controller (MDC) or a vehicle domain controller (VDC), is used to execute the control method in this application embodiment, which can reduce the temperature of the component to be cooled.

[0157] For example, refer to Figure 12The controller in the vehicle may also include an air intake grille controller 500 and a fully active suspension controller 510. Exemplarily, the air intake grille controller 500 and the fully active suspension controller 510 are electrically connected. The air intake grille controller 500 is electrically connected to the drive element of the air intake grille 400, the fully active suspension controller 510 is electrically connected to the fan 200, and the fully active suspension controller 510 is electrically connected to the temperature sensor 310 of the component to be cooled 300.

[0158] The air intake grille controller 500 is used to send control signals to the drive component controlling the air intake grille 400, so that the drive component of the air intake grille 400 can drive the air intake grille 400 to open or close. The fully active suspension controller 510 is used to send control signals to the drive component of the fan 200, so that the drive component of the fan 200 can drive the fan to open or close, etc. The fully active suspension controller 510 can also be used to acquire first information, exemplarily, the first information is information detected by the temperature sensor 310 located on the component to be cooled 300.

[0159] Optionally, the control device and control method in the embodiments of this application can be applied to, but are not limited to, vehicle systems. The vehicle equipped with the vehicle system is an intelligent driving vehicle and can be replaced by a terminal device. The terminal device can be, but is not limited to, vehicles such as commercial vehicles, passenger cars, trains, etc., industrial vehicles (such as forklifts, trailers, tractors, etc.), and engineering vehicles (such as excavators, bulldozers, cranes, etc.). The embodiments of this application do not specifically limit this.

[0160] In this embodiment, by setting an airflow channel on the subframe, when the temperature of the component to be cooled is too high, the airflow provided by the fan is sent to the component to be cooled through the airflow channel, which can reduce the temperature of the component to be cooled, so that the component to be cooled can work normally, thereby improving the comfort and safety of the vehicle.

[0161] The following describes how to control the fan when the first piece of information includes the temperature information of the component to be cooled.

[0162] For example, the control signal includes a first control signal; generating the control signal based on the first information includes: generating the first control signal when the first information indicates that the temperature of the component to be cooled is greater than or equal to a first threshold, the first control signal being used to control the fan to be in a working state. For example, the first threshold can be 100°C. That is, when the fully active suspension controller obtains the temperature information of the component to be cooled detected by the temperature sensor as greater than or equal to the first threshold, it generates the first control signal and sends the first control signal to the fan drive, causing the fan drive to drive the fan to be in a working state. In this embodiment, the fan is only controlled to turn on when the temperature of the component to be cooled is higher than the first threshold, which can save energy.

[0163] For example, the power of the fan during operation is positively correlated with the temperature of the component being cooled.

[0164] In other words, the fan can be a continuously variable speed fan. When the temperature of the component to be cooled is higher than the first threshold, the fan speed can increase as the temperature of the component to be cooled increases, and the fan speed can decrease as the temperature of the component to be cooled decreases, so as to save energy while reducing the temperature of the component to be cooled.

[0165] For example, the first control signal is also used to indicate information about the operating state of the fan, which includes at least a first operating state and a second operating state, wherein the power of the fan in the first operating state is different from the power of the fan in the second operating state.

[0166] For example, the power in the first operating state can be less than the power in the second operating state. The fan can include a first speed and a second speed, where the first operating state can be the fan being at speed one, and the second operating state can be the fan being at speed two. When the temperature of the component to be cooled is higher than a first threshold but lower than a third threshold, the fan can be turned on at speed one; when the temperature of the component to be cooled is higher than the third threshold, the fan can be turned on at speed two. The third threshold is greater than the first threshold, for example, the third threshold can be 120 degrees Celsius. In this embodiment, the higher the temperature of the component to be cooled, the higher the fan speed, the higher the power, so as to quickly reduce the temperature of the component to be cooled. After the temperature of the component to be cooled decreases, the fan speed can be reduced, and the corresponding fan speed and power decrease, which can save energy and reduce the temperature of the component to be cooled.

[0167] For example, the control signal includes a second control signal; generating the control signal based on the first information includes: generating the second control signal when the temperature of the component to be cooled, as indicated by the first information, is less than a second threshold, and the second control signal is used to control the fan to be in a closed state. The second threshold is less than the first threshold; for example, the second threshold can be 90 degrees Celsius. Setting the second threshold to be less than the first threshold can prevent the fan from frequently turning on and off.

[0168] In this embodiment, when the temperature of the component to be cooled, detected by the temperature sensor, is less than a second threshold, the fully active suspension controller generates a second control signal and sends it to the fan drive, causing the fan drive to shut down the fan. In this embodiment, once the temperature of the component to be cooled drops to a safe range, the fan can be controlled to shut down to save energy.

[0169] The fan can be controlled to be either off or on based on the temperature of the component being cooled. The air intake grille can also be controlled to be open or closed based on the status of the fan.

[0170] For example, when the fan is turned on based on the temperature of the component to be cooled, the air intake grille can also be turned on. That is, the first control signal is also used to control the air intake grille to be turned on. For example, the fully active suspension controller can send the first control signal to the air intake grille controller. After receiving the first control signal, the air intake grille controller sends a control signal to the drive component of the air intake grille, causing the drive component of the air intake grille to drive the air intake grille to be turned on.

[0171] In this embodiment, when the temperature of the component to be cooled exceeds a first threshold, the fan starts and simultaneously the air intake grille is opened, allowing outside air to enter the mounting channel. The airflow is blown by the fan within the mounting channel into the intake channel, then into the airflow channel, and finally into the exhaust channel, ultimately reaching the component to be cooled. With the air intake grille open, airflow during vehicle operation can naturally enter the mounting channel, increasing airflow velocity and volume, and improving heat dissipation efficiency.

[0172] Similarly, when the fan is turned off based on the temperature of the component being cooled, the air intake grille can also be controlled to close. That is, the second control signal is also used to control the air intake grille to close. The fully active suspension controller can send the second control signal to the air intake grille controller, which, upon receiving the second control signal, sends it to the air intake grille's drive mechanism, causing the drive mechanism to close the air intake grille.

[0173] refer to Figure 13 , Figure 13 A flowchart of another control method provided in an embodiment of this application. (In conjunction with...) Figure 13 The document describes a detailed process of first determining the fan status based on the temperature of the component to be cooled, and then determining the air intake grille status based on the fan status.

[0174] S21: Obtain first information, which includes the temperature information of the component to be cooled.

[0175] S22: Determine whether the temperature information indicated by the first information is greater than or equal to the first threshold. If yes, proceed to step S23; otherwise, return to step S21.

[0176] S23: Generate a first control signal, which is used to control the fan to be in working state and to control the air intake grille to be in open state.

[0177] S24: Determine whether the temperature information indicated by the first information is less than the second threshold. If yes, proceed to step S25; otherwise, return to step 23.

[0178] S25: Generate a second control signal, which is used to control both the fan and the air intake grille to be in the closed state.

[0179] In this embodiment, when the fan is off, it indicates that the temperature of the component to be cooled has dropped to a safe range. At this time, the air intake grille can be closed simultaneously to prevent foreign objects from entering the air intake grille. That is, when the temperature of the component to be cooled is too high, both the fan and the air intake grille are open; when the temperature of the component to be cooled is normal, both the fan and the air intake grille are closed.

[0180] In this embodiment, the state of the fan is first determined based on the temperature of the component to be cooled, and then the state of the air intake grille is determined based on the state of the fan. This can not only enable the component to be cooled to be cooled efficiently, but also save resources.

[0181] Alternatively, the grille can be closed independently of the fan. With the fan off, the grille's closure can be determined by the engine temperature. When the engine temperature is too high, the grille can be opened to allow natural airflow into the engine compartment to cool the engine. When the engine temperature is normal, the grille can be closed to prevent foreign objects from entering the engine compartment.

[0182] In other words, after receiving the second control signal, the grille controller then obtains the signal from the temperature sensor that detects the engine temperature. Based on this signal, it determines the engine temperature. If the engine temperature is too high, it can control the grille to open. When the engine temperature is normal, it can control the grille to close. The grille controller can be directly electrically connected to the engine temperature sensor, or it can obtain the engine temperature sensor signal through the engine controller, or it can obtain the desired state of the grille directly from the engine controller.

[0183] The following describes how to control the fan when the first information includes the status information of the vehicle's air intake grille.

[0184] In some possible embodiments, the control signal includes a first control signal; generated when the first information indicates that the air intake grille is in an open state, the first control signal is used to control the fan to be in an operating state. The fully active suspension controller can obtain the state of the air intake grille from the air intake grille controller.

[0185] In this embodiment, the air intake grille being open indicates that the engine temperature is too high. Since the component to be cooled and the engine are in the same space, the heat emitted by the engine may affect the component, causing its temperature to rise too high. In this case, the fan can be turned on to cool the component. That is, the state of the air intake grille is determined based on the engine temperature, and then the fan's state is determined based on the state of the air intake grille.

[0186] In some possible embodiments, the control signal further includes a second control signal; the control method further includes generating a second control signal when the air intake grille switches from an open state to a closed state, the second control signal being used to control the fan to be in a closed state.

[0187] In this embodiment, when the air intake grille is closed, it indicates that the engine temperature has returned to normal, and the heat emitted by the engine will no longer affect the components being cooled. At this time, the fan can also be turned off to save resources.

[0188] In this embodiment, the state of the fan is determined according to the state of the air intake grille, which can both avoid the temperature of the component to be cooled being too high and save resources.

[0189] Alternatively, after the air intake grille switches from the open to the closed state, the fan may not close synchronously with the air intake grille. In this case, the fan status can be determined based on the temperature of the component being cooled, to avoid a situation where the engine has returned to normal operation, but the temperature of the component being cooled has not yet returned to normal.

[0190] For example, when the air intake grille switches from an open state to a closed state, generating a second control signal includes: generating the second control signal when the air intake grille switches from an open state to a closed state and the temperature of the component to be cooled is less than a second threshold. That is, when the air intake grille is closed and the temperature of the component to be cooled is within the normal range, the fan is controlled to turn off to save resources.

[0191] In some possible embodiments, the control method further includes: controlling the fan to operate when the air intake grille switches from an open state to a closed state and the temperature of the component to be cooled is greater than or equal to a first threshold. That is, even though the air intake grille is closed, if the temperature of the component to be cooled is still too high, the fan is turned on to cool the component.

[0192] For example, the specific method of controlling the operating state of the fan based on the temperature information of the component to be cooled can be referred to in the above embodiments.
