[0004] In electric vehicles, the radiator is typically located inside the front air scoop. The windward sidewall of the scoop is equipped with an air inlet duct, allowing the oncoming wind to dissipate heat while the vehicle is in motion. Furthermore, a fan is installed inside the scoop to force ventilation and dissipate heat when the vehicle is idling.

DETAILED DESCRIPTION

[0057] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0058] For ease of understanding, each key term or important term involved in the present invention is explained below:

[0059] Three-electric system: The electric motor, power battery and electronic control system are known as the three core components of new energy vehicles, and the three are collectively called the three-electric system.

[0060] In addition, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. In the description of the following embodiments, "plurality" means more than two, unless otherwise specifically defined.

[0061] Electric vehicles are vehicles that use an onboard power source to propel their wheels, using an electric motor and complying with all road traffic and safety regulations. Their development prospects are widely optimistic due to their lower environmental impact compared to traditional vehicles.

[0062] It is understandable that electric vehicles generate a large amount of heat when working. The vehicle cooling system, as a heat exchange element between the three-electric system and the vehicle's air-conditioning system, not only needs to take away the heat dissipated by the motor, electronic control system and power battery under various working conditions, so that the motor, electronic control system and power battery are within the normal operating temperature range and have excellent performance; but also needs to take away the heat inside the vehicle cabin when necessary, and provide cool air inside the vehicle cabin to improve the comfort of the vehicle.

[0063] In conventional technology, the cooling module of an electric vehicle is typically located within the front-end air scoop, comprising a radiator, condenser, and fan. Specifically, an air inlet duct is provided on the windward sidewall of the air scoop, communicating with the scoop. This allows the vehicle to dissipate heat through oncoming wind while driving, and through forced ventilation from the fan when idling.

[0064] It is understandable that due to the complex thermal management system of electric vehicles, the cooling performance requirements of electric vehicles are higher than those of fuel vehicles, resulting in the larger size of their cooling modules, which has a greater impact on the layout and design of the complex three-electric system in the front cabin of the vehicle. In addition, electric vehicles have a low drag coefficient requirement, which requires the front of the vehicle to be as low as possible and occupy a small amount of height space in the vehicle. Furthermore, if the demand for front trunk storage space is to be met, the air intake space of the air scoop will be greatly compressed, resulting in poor heat dissipation performance of the vehicle, which in turn easily leads to frequent problems such as overheating of the motor and battery, which is not conducive to improving the safety factor of the vehicle.

[0065] The present application provides an air intake flow control system, a control method, a vehicle, and an air scoop to solve the above-mentioned problems. Specifically, in the system of the present application, the top of the first side wall of the air scoop is rotatably connected to the top of the air scoop, the air intake channel is connected between the bottom of the first side wall and the bottom wall of the air scoop, and the top of the air intake channel is connected to the bottom of the first side wall by a flexible member. The top of the second side wall of the front trunk is rotatably connected to the top of the front trunk, the bottom of the second side wall is connected to the bottom wall of the front trunk by a flexible member, and the first side wall is arranged parallel to the second side wall. Through the system of the present application, when the vehicle has a heat dissipation demand, the first side wall and the second side wall are synchronously driven to rotate in a direction away from the radiator to increase the air intake space of the air scoop and increase the air intake flow, thereby improving the heat dissipation performance of the vehicle. When the vehicle no longer has a heat dissipation demand, the first side wall and the second side wall are synchronously driven to rotate in a direction close to the radiator to increase the storage space of the front trunk to meet the storage requirements.

[0066] It can be understood that the air intake flow control system protected by this application can be applied to any vehicle; the air guide cover protected by this application can be applied to any equipment with heat dissipation requirements and space requirements, and for example, it can be applied to air-conditioning equipment, refrigerator equipment, etc.

[0067] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the event that the embodiments do not conflict with each other, the following embodiments and features therein may be combined with each other.

[0068] An embodiment of the present application provides an air intake flow control system. Figure 1 is a schematic diagram of the principle of an air intake flow control system provided by an embodiment of the present application. As shown in Figure 1, the system of this embodiment includes: an air guide cover 1, a heat dissipation module 2 and a front trunk 3.

[0069] The side wall of the air scoop 1 near the front trunk 3 is a first side wall 11. An air inlet duct 4 communicating with the air scoop 1 is provided between the first side wall 11 and the bottom wall of the air scoop 1. The air inlet duct 4 is located below the front trunk 3. Specifically, the first side wall 11 is arranged parallel to a second side wall 31 of the front trunk 3 near the air scoop 1. The top of the first side wall 11 is rotatably connected to the top of the air scoop 1, the bottom of the first side wall 11 is connected to the top of the air inlet duct 4 via a connector, the top of the second side wall 31 is rotatably connected to the top of the front trunk 3, and the bottom of the second side wall 31 is also connected to the bottom wall of the front trunk 3 via a connector.

[0070] In this embodiment, the heat dissipation module 2 includes a radiator 21, a condenser 22, and a fan 23, which are sequentially arranged inside the air scoop 1 and bolted to the inner wall of the air scoop 1. The radiator 21 is closest to the air inlet channel 4, and the fan 23 is farthest from the air inlet channel 4.

[0071] In this embodiment, both the first side wall 11 and the second side wall 31 are inclined, with the inclination direction being from a direction closer to the radiator 21 to a direction away from the radiator 21. Specifically, the inclination angles of the first side wall 11 and the second side wall 31 are determined to suit the specific space requirements of the vehicle's front cabin and are not limited in this embodiment.

[0072] In this embodiment, the top of the first side wall 11 is rotatably connected to the top of the air scoop 1 via a first rotating shaft 12. Specifically, the first rotating shaft 12 is rotatably connected to the top of the air scoop 1 and fixedly connected to the top of the first side wall 11. The top of the second side wall 31 is rotatably connected to the top of the front trunk 3 via a second transmission shaft. Specifically, the second rotating shaft 32 is rotatably connected to the top of the front trunk 3 and fixedly connected to the top of the second side wall 31.

[0073] It is understandable that one first rotating shaft 12 can be provided, located on the top of the air scoop 1 near the front trunk 3, rotatably connected to the top of the air scoop 1, and fixedly connected to the middle position of the top of the first side wall 11; two first rotating shafts 12 can also be provided, located on both sides of the top of the first side wall 11, fixedly connected to the first side wall 11, and rotatably connected to the top of the air scoop 1 near the front trunk 3. Similarly, one second rotating shaft 32 can be provided, or two second rotating shafts 32 can be provided. In this embodiment, the number of the first rotating shaft 12 and the second rotating shaft 32 is not limited, nor is the rotational connection method between the top of the first side wall 11 and the top of the air scoop 1, or the rotational connection method between the top of the second side wall 31 and the top of the front trunk 3 limited. As long as the rotational connection between the top of the first side wall 11 and the top of the air scoop 1, and the rotational connection between the top of the second side wall 31 and the top of the front trunk 3 can be achieved, it will be sufficient.

[0074] As shown in Figure 1 , the system of this embodiment further includes a first drive member 8 and a second drive member 9. Specifically, the first drive member 8 is a first motor, and the second drive member 9 is a second motor. The output shaft of the first motor is coaxially fixed with the first rotating shaft 12 to drive the first rotating shaft 12 to rotate; the output shaft of the second motor is coaxially fixed with the second rotating shaft 32 to drive the second rotating shaft 32 to rotate. In this embodiment, the first motor is fixedly mounted outside the air scoop 1, and the second motor is fixedly mounted outside the front trunk 3.

[0075] It is understandable that, in actual applications, considering the convenience of the motor setting position, the first driving member 8 can also be a combination of a first motor and a gear set. In this embodiment, the specific form of the driving member is not limited, as long as it can drive the rotating shaft to rotate. Exemplarily, the first driving member 8 is a combination of a first motor and a bevel gear set, the gear in the bevel gear set that rotates in the same direction as the first rotating shaft 12 is the first gear, the gear that rotates in the same direction as the output shaft of the first motor is the second gear, the first gear is meshed with the second gear, the first gear is coaxially fixed to the first rotating shaft 12, and the second gear is coaxially fixed to the output shaft of the first motor.

[0076] As shown in Figure 1, the connecting member in this embodiment is specifically a flexible member 5. Based on the flexible member 5, the first side wall 11 can rotate in the direction of approaching or away from the heat dissipation module 2 with the first rotation axis 12 as the rotation axis without damaging the structure. In actual applications, the connecting member can also be a hinge with a limiting function. Specifically, the two ends of the hinge parallel to the hinge axis are fixedly connected to the bottom of the first side wall 11 and the top of the air inlet channel 4 respectively. In this embodiment, the specific shape and material of the connecting member are not limited, as long as the first side wall 11 can be rotated under the cooperation of the first driving member 8 and the connecting member.

[0077] As shown in Figure 1, the system of this embodiment also includes a control device 6 and a monitoring device 7, wherein the signal input end of the control device 6 is connected to the signal output end of the monitoring device 7 for obtaining a monitoring signal, and the monitoring signal is used to indicate whether there is a heat dissipation demand; the control device 6 is used to issue a control instruction to the first drive member 8 and the second drive member 9 based on the monitoring signal; the first drive member 8 is used to drive the first side wall 11 to rotate when receiving the control instruction; the second drive member 9 is used to drive the second side wall 31 to rotate when receiving the control instruction.

[0078] It can be understood that the monitoring device 7 is used to monitor any factor that may generate heat dissipation needs. For example, it can be used to directly monitor the vehicle temperature, or it can be used to monitor the vehicle operating status, or it can be used to monitor the vehicle operating environment, or it can be a combination of at least one factor, which is not limited in this embodiment.

[0079] In the system of this embodiment, the monitoring device 7 transmits a monitoring signal to the control device 6. When the monitoring signal indicates that there is a need for heat dissipation, the control device 6 issues a control instruction to the first drive member 8 and the second drive member 9, so that the first drive member 8 and the second drive member 9 synchronously drive the first side wall 11 and the second side wall 31 to rotate in a direction away from the radiator 21, thereby increasing the air intake space of the air guide 1 and the air intake flow, so that more air can enter the radiator 21 and the condenser 22, thereby improving the heat dissipation efficiency and reducing the risk of frequent overheating of the motor and the battery. Furthermore, when the monitoring signal indicates that there is no longer a need for heat dissipation, the control device 6 issues a control instruction to the first drive member 8 and the second drive member 9, so that the first drive member 8 and the second drive member 9 respectively drive the first side wall 11 and the second side wall 31 to rotate in a direction close to the radiator 21, thereby increasing the space of the front trunk 3 to meet the storage demand.

[0080] The system of this embodiment can achieve a reasonable balance between heat dissipation and storage space when front cabin space is limited. When heat dissipation is prioritized, the system controls the airflow angle, occupies a small amount of storage space, and significantly improves heat dissipation performance. After the system temperature drops, it returns to the default position to maintain normal heat dissipation and storage. This system can help the entire vehicle cope with real-time changing heat dissipation needs, effectively utilize internal space, and maintain a compact front cabin, controllable temperature, and safe and reliable operation.

[0081] Figure 2 is a second schematic diagram of the principle of an intake flow control system provided in an embodiment of the present application. Based on the previous embodiment, this embodiment specifically defines the connection method between the first side wall 11 and the top of the air guide cover 1, the connection method between the second side wall 31 and the top of the front trunk 3, and the functions of the control device 6 and the monitoring device 7.

[0082] As shown in Figure 2, in this embodiment, the first driving member 8 is specifically a first motor, and the second driving member 9 is specifically a second motor. A single first rotating shaft 12 is located at the top of the air scoop 1, near the front trunk 3, rotatably connected to the top of the air scoop 1, and fixedly connected to the middle of the top of the first side wall 11. A single second rotating shaft 32 is located at the top of the front trunk 3, near the air scoop 1, rotatably connected to the top of the front trunk 3, and fixedly connected to the middle of the top of the second side wall 31.

[0083] As shown in Figure 2, in this embodiment, the monitoring device 7 includes a temperature monitoring module, an operating status monitoring module, and an operating environment monitoring module. The temperature monitoring module is used to obtain a vehicle temperature signal to indicate the vehicle temperature; the operating status monitoring module is used to obtain a vehicle operating status signal to indicate the vehicle's operating mode; and the operating environment monitoring module is used to obtain a vehicle operating environment signal to indicate the vehicle's operating environment.

[0084] It is understood that the operating mode includes a normal mode and a high-speed operating mode, and the vehicle is considered to have a heat dissipation requirement when in the high-speed operating mode. The operating environment includes a normal environment and a high-temperature environment, and the vehicle is considered to have a heat dissipation requirement when in the high-temperature environment.

[0085] Based on this, the control device 6 is used to obtain a preset mapping table when the monitoring signal meets at least one of the first preset conditions, determine the rotation angle according to the preset mapping table, and send a control instruction to the first driving member 8 and the second driving member 9 to control the first side wall 11 and the second side wall 31 to rotate away from the radiator 21 until the angle between the first side wall 11 and the top of the air guide cover 1 is equal to the rotation angle.

[0086] The preset mapping table is used to indicate a mapping relationship between temperature values ​​and angle values, where the temperature value corresponds to the vehicle temperature, and the angle value indicates the angle between the first side wall 11 and the top of the air scoop 1. For example, one set of mapping relationships may be 35°C-20°, indicating that when the vehicle temperature is 35°C, the angle value should be 20°. In actual applications, the preset mapping table may be configured based on the rule that the angle value increases by 1° for every 2°C increase in temperature. Other rules may also be used to configure the preset mapping table, as long as the temperature increases and the angle value increases synchronously. This is not limited in this embodiment.

[0087] In this embodiment, the first preset condition includes: the vehicle temperature indicated by the vehicle temperature signal is not less than a preset value, the vehicle operating status signal indicates that the vehicle operating mode is a high-speed operating mode, and the vehicle operating environment signal indicates that the vehicle operating environment is a high-temperature environment.

[0088] In this embodiment, the control device 6 is further configured to, when the monitoring signal satisfies a second preset condition, issue a control instruction to the first driving member 8 and the second driving member 9 for controlling the first side wall 11 and the second side wall 31 to synchronously rotate toward the radiator 21. The second preset condition includes: the vehicle temperature indicated by the vehicle temperature signal is less than a preset value; the vehicle operating state signal indicates that the vehicle operating mode is normal; and the vehicle operating environment signal indicates that the vehicle operating environment is normal.

[0089] It is understood that when the control device 6 detects a need for heat dissipation, it drives the first side wall 11 and the second side wall 31 to rotate away from the radiator 21, thereby increasing the air intake space. This, in turn, increases the air intake flow rate, which in turn improves heat dissipation efficiency and more quickly reaches a state where no heat dissipation is required. In this case, when the control device 6 detects no need for heat dissipation, it controls the first side wall 11 and the second side wall 31 to rotate toward the radiator 21, thereby increasing the storage space of the front trunk 3 and meeting storage requirements.

[0090] Optionally, in this embodiment, the control device 6 is also used before issuing a control instruction to: obtain the storage information of the front trunk 3, and determine whether the storage information meets any one of the third preset conditions; if so, determine to issue a control instruction to the first driving member 8 and the second driving member 9 for controlling the first side wall 11 and the second side wall 31 to rotate in a direction away from the radiator 21.

[0091] The third preset condition includes that there is no stored item in the front trunk 3 , the stored items in the front trunk 3 can be squeezed, and there is a surplus in the front trunk 3 .

[0092] It is understood that the system of this embodiment may further include a photographing device, which is located inside the front trunk 3 and is used to photograph the interior of the front trunk 3, obtain an interior image, and transmit the interior image to the control device 6. The control device 6 determines whether there are any stored items in the front trunk 3, whether the stored items in the front trunk 3 are squeezable, and whether there is a remaining amount in the front trunk 3 based on the interior image and image processing technology. The specific processing steps are all existing technologies and will not be repeated here.

[0093] In the system of this embodiment, the control device 6 adjusts the first side wall 11 and the second side wall 31 based on the monitoring signal and a preset mapping table, thereby meeting the heat dissipation requirements while also facilitating the storage needs of the front trunk 3. Furthermore, before adjusting the first and second side walls 11 and 31, the control device 6 monitors the presence of stored items in the front trunk 3. If so, the control device 6 further determines whether the stored items are squeezeable and whether there is sufficient space in the front trunk 3, thereby effectively protecting the stored items in the front trunk 3.

[0094] The present application also provides a vehicle. Figure 3 is a schematic structural diagram of a vehicle provided in the present application. As shown in Figure 3, the vehicle of this embodiment includes a vehicle body and the air flow control system of the aforementioned embodiment. When the vehicle needs to dissipate heat, the air flow control system increases the air flow rate of the vehicle's air scoop to improve the vehicle's heat dissipation efficiency. The specific application process can be found in the aforementioned embodiment and will not be repeated here.

[0095] The embodiment of the present application also provides an air guide cover. The specific structure of the air guide cover is shown in Figures 1 and 2. The detailed structural description is shown in the aforementioned embodiment, which will not be repeated here.

[0096] The present application also provides an intake air flow control method. FIG4 is a flow chart of an intake air flow control method provided by the present application. It is worth noting that the method of the present embodiment is executed by the above-mentioned control device. Specifically, as shown in FIG4, the method provided by the present embodiment includes:

[0097] S401, obtaining a monitoring signal.

[0098] Specifically, the monitoring signals include vehicle temperature signals, vehicle operating status signals, and vehicle operating environment signals.

[0099] It can be understood that in this embodiment, the control device obtains the vehicle temperature signal through the temperature monitoring module, obtains the vehicle operating status signal through the vehicle operating status monitoring module, and obtains the vehicle operating environment signal through the vehicle operating environment monitoring module.

[0100] S402 : When the monitoring signal satisfies any one of the first preset conditions, a control instruction for controlling the first side wall and the second side wall to rotate in a direction away from the radiator is issued to the first driving member and the second driving member.

[0101] Among them, the first preset condition includes: the vehicle temperature indicated by the vehicle temperature signal is not less than the preset value, the vehicle operation status signal indicates that the vehicle operation mode is a high-speed operation mode, and the vehicle operation environment signal indicates that the vehicle operation environment is a high-temperature environment.

[0102] It can be understood that when the vehicle temperature is not less than the preset value, when the vehicle's operating mode is a high-speed operating mode, and when the vehicle's operating environment is a high-temperature environment, it is considered that there is a need for heat dissipation. Therefore, when the monitoring signal meets any one of the first preset conditions, the control device sends a control instruction to the first drive member and the second drive member to control the first side wall and the second side wall to rotate away from the radiator, so as to dissipate heat in time and avoid damage to the vehicle.

[0103] S403 : When the monitoring signal satisfies a second preset condition, a control instruction for controlling the first side wall and the second side wall to rotate toward the radiator is sent to the first driving member and the second driving member.

[0104] Among them, the second preset condition includes: the vehicle temperature indicated by the vehicle temperature signal is less than a preset value, the vehicle operation status signal indicates that the vehicle operation mode is normal mode, and the vehicle operation environment signal indicates that the vehicle operation environment is normal environment.

[0105] It can be understood that when the monitoring signal meets each of the second preset conditions, it is considered that there is no longer a need for heat dissipation. Only then is a control instruction sent to the first driving member and the second driving member to control the first side wall and the second side wall to rotate toward the radiator to restore the storage space of the front trunk.

[0106] Through the method provided in this embodiment, when heat dissipation demand is detected, the first side wall and the second side wall can be rotated in time to increase the air intake space, thereby increasing the air intake flow and increasing the heat dissipation efficiency; when it is detected that there is no longer a heat dissipation demand, the first side wall and the second side wall can be rotated in time to restore the storage space of the front trunk, thereby restoring the powerful storage capacity of the front trunk.

[0107] FIG5 is a second flow chart of an intake air flow control method provided in an embodiment of the present application. Specifically, based on the aforementioned method embodiments, this embodiment further limits the control instructions issued and the timing of issuing the control instructions. Specifically, as shown in FIG5 , the method of this embodiment includes:

[0108] S501, obtaining a monitoring signal.

[0109] Specifically, the monitoring signals include vehicle temperature signals, vehicle operating status signals, and vehicle operating environment signals.

[0110] S502 : When the monitoring signal satisfies any one of the first preset conditions, obtain storage information of the front trunk, and determine whether the storage information satisfies any one of the third preset conditions.

[0111] Among them, the third preset condition includes that there is no stored item in the front trunk, the stored items in the front trunk can be squeezed, and there is a surplus in the front trunk.

[0112] In this embodiment, a camera is installed in the front trunk. The control device uses the camera to capture images of the interior and, through image processing techniques, obtains storage information. Specifically, the storage information indicates whether there are items stored in the front trunk. If there are items stored in the front trunk, the storage information also indicates whether the stored items are squeezable and whether there is sufficient space in the trunk.

[0113] It is understandable that in actual applications, in order to effectively protect the items in the front trunk, the storage information can be determined to meet the third preset condition only when the storage information indicates that the front trunk remaining capacity meets the maximum rotation angle of the second side wall, or the stored items can be squeezed, or there are no stored items in the front trunk.

[0114] S503: If yes, obtain a preset mapping table and determine the rotation angle according to the preset mapping table.

[0115] The preset mapping table is used to indicate a mapping relationship between temperature values ​​and angle values, the temperature value corresponds to the vehicle temperature, and the angle value is used to indicate an angle between the first side wall and the top of the air guide cover.

[0116] S504: Send a control instruction to the first driving member and the second driving member to control the first side wall and the second side wall to rotate away from the radiator until the angle between the first side wall and the top of the air guide cover is equal to the rotation angle.

[0117] S505 : When the monitoring signal satisfies a second preset condition, a control instruction for controlling the first side wall and the second side wall to rotate toward the radiator is issued to the first driving member and the second driving member.

[0118] Among them, the second preset condition includes: the vehicle temperature indicated by the vehicle temperature signal is less than a preset value, the vehicle operation status signal indicates that the vehicle operation mode is normal mode, and the vehicle operation environment signal indicates that the vehicle operation environment is normal environment.

[0119] In the method provided in this embodiment, the control device first determines whether there is a need for heat dissipation based on the monitoring signal. If there is a need for heat dissipation, the control device further determines whether the storage information of the front trunk meets a third preset condition. If so, the control device determines a rotation angle based on a preset mapping table, and finally issues a control instruction to the first and second drive members based on the rotation angle. Furthermore, when there is no longer a need for heat dissipation, the control device issues a control instruction to the first and second drive members to rotate them toward the radiator to restore the storage space in the front trunk.

[0120] The method provided in this embodiment improves heat dissipation by controlling the angle of the air scoop, helping to meet the high cooling requirements of electric vehicles and preventing the risk of thermal runaway caused by overheating. When properly coupled with the front trunk's movement, this improves heat dissipation without compromising conventional storage functions, meeting the diverse needs of users in harsh, hot conditions.
