Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and more particularly to a front structure of a vehicle and a vehicle. Background Technology

[0002] In related technologies, current automotive aerodynamics technology is developing towards intelligence, integration, and multi-objective optimization. Although Active Grille System (AGS) has achieved significant results in improving automotive aerodynamic performance, engine thermal management, and fuel economy, existing technologies still face systemic challenges. Specifically, current AGS focuses on single-function optimization (such as intake control or drag regulation), lacking the ability to coordinate and regulate multiple objectives such as aerodynamics, thermal management, and energy consumption under various operating conditions, including high-speed driving, cold starts in low temperatures, high-temperature heat dissipation, and brake cooling. Its mechanical structure is usually independently arranged, with low integration with front-end styling, cooling modules, and sensor layout, occupying a large space and hindering vehicle lightweighting and modular design. Control strategies rely heavily on rule logic with preset thresholds, lacking sufficient perception and learning capabilities for real-time operating conditions, environmental parameters, and driving behavior, making it difficult to achieve refined and predictive adjustments. Furthermore, as a key area for airflow control, the hood and its grille currently generally lack active adjustment mechanisms, missing opportunities to further optimize the front-end flow field distribution, reduce pressure drag, and improve lift control capabilities. Summary of the Invention

[0003] This application provides a front structure for a vehicle, which aims to improve fuel economy during high-speed cruising or the driving range of pure electric vehicles, achieve energy conservation and emission reduction, enhance air pressure at the front of the vehicle, actively increase downforce at the front of the vehicle, enhance front wheel grip, effectively suppress the "floating" phenomenon of the front of the vehicle during high-speed driving, and improve high-speed driving stability.

[0018] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0019] This application provides a vehicle front structure 100, including: engine compartment cover 2, air intake assembly 3 and air exhaust assembly 4.

[0020] Specifically, such as Figure 1 and Figure 3 As shown, the front structure 100 of the vehicle forms an airflow channel 1. The airflow channel 1 has an air inlet 11 and an air outlet 12 at both ends, both communicating with the airflow channel 1. The air outlet 12 is formed in the engine compartment cover 2. An air intake assembly 3 is movably disposed at the position of the air inlet 11 to open or close the air inlet 11, and an air outlet assembly 4 is movably disposed at the position of the air outlet 12 to open or close the air outlet 12. It can be understood that the front structure 100 of the vehicle includes an engine compartment cover 2, an air intake assembly 3, and an air outlet assembly 4. The airflow channel 1 is used to guide air in or out. An air inlet 11 is formed at the front end of the airflow channel 1, communicating with the airflow channel 1 to guide air into the airflow channel 1. An air outlet 12 is formed at the rear end of the airflow channel 1, communicating with the airflow channel 1 to guide air out of the airflow channel 1. The air intake assembly 3 is movably located at the air intake 11. When the air intake assembly 3 closes the air intake 11, it blocks the entry of external airflow and reduces wind resistance. When the air intake assembly 3 opens the air intake 11, it allows external cold air to enter the cabin for cooling the power system. The air exhaust assembly 4 is movably located at the air exhaust 12. When the air exhaust assembly 4 closes the air exhaust 12, it prevents external backflow or reduces airflow leakage inside the cabin. When the air exhaust assembly 4 opens the air exhaust 12, it allows hot air inside the cabin to be smoothly discharged.

[0021] Furthermore, the vehicle front structure 100 has three interchangeable states: a first state, a second state, and a third state. When the vehicle front structure 100 is in the first state, such as... Figure 1 and Figure 2 As shown, the intake assembly 3 closes the intake port 11, and the exhaust assembly 4 closes the exhaust port 12. When the front structure 100 of the vehicle is in the second state, as... Figure 3 and Figure 4 As shown, the intake assembly 3 opens the intake port 11, and the exhaust assembly 4 opens the exhaust port 12. When the front structure 100 of the vehicle is in the third state, as... Figure 8 and Figure 9As shown, the air intake assembly 3 opens the air intake port 11, and the air exhaust assembly 4 rotates upward around the Y-axis to a position perpendicular to the nacelle cover 2. Understandably, in the first state, both the air intake 11 and the air outlet 12 are closed, minimizing the amount of oncoming airflow entering the engine compartment, thereby reducing the overall vehicle drag coefficient. This is suitable for high-speed cruising conditions and can effectively improve energy efficiency (e.g., saving fuel consumption in gasoline vehicles or extending the range of electric vehicles). In the second state, both the air intake 11 and the air outlet 12 are open, forming a complete airflow channel 1 from front to rear. Cold air enters the engine compartment from the air intake 11 located at the front, and hot air is discharged from the air outlet 12 on the hood. This is suitable for high-load driving, high-temperature environments, or cold start stages requiring rapid warm-up, ensuring thermal management of the powertrain. In the third state, the air intake 11 is open, and the air outlet assembly 4 is vertically erected. Because the vertically erected air outlet assembly 4 drastically changes the airflow field above the hood, it enhances the air pressure at the front of the vehicle, thereby actively increasing downforce at the front and improving high-speed driving stability. When deceleration is required (e.g., high-speed braking), the erected air outlet assembly 4 can increase air resistance, acting as an air brake, improving braking performance and safety.

[0022] Reference Figure 1 and Figure 2 As shown, this is the first state, with both the air inlet 11 and the air outlet 12 closed; refer to... Figure 3 and Figure 4 As shown, this is the second state, with both the air inlet 11 and the air outlet 12 open; refer to... Figure 8 and Figure 9 As shown, this is the third state, with the air inlet 11 open and the air outlet assembly 4 standing vertically.

[0023] According to the vehicle front structure 100 of the present application embodiment, by realizing the coordinated active control of the air intake 11 and the air outlet 12 on the hood, the fuel economy of the vehicle during high-speed cruising or the driving range of pure electric vehicles can be improved, achieving energy conservation and emission reduction. It can also enhance the air pressure at the front of the vehicle, thereby actively increasing the downforce at the front of the vehicle, enhancing the grip of the front wheels, effectively suppressing the "floating" phenomenon of the front of the vehicle during high-speed driving, improving high-speed driving stability, and improving the stability and steering precision of the vehicle at high speed.

[0024] It should be noted that in this embodiment and other embodiments, a vehicle coordinate system is used, with its origin coinciding with the center of mass. When the vehicle is stationary on a horizontal road surface, the X direction is parallel to the ground and represents the vehicle's front-to-back direction, the Z direction passes through the vehicle's center of mass and represents the vehicle's up-to-down direction, and the Y direction represents the vehicle's left-to-right direction.

[0025] In some embodiments of this application, the exhaust assembly 4 includes an exhaust grille assembly 41 and an exhaust drive 43. One end of the exhaust grille assembly 41 in the longitudinal direction is connected to the nacelle cover 2. The exhaust drive 43 is drively connected to the exhaust grille assembly 41 to drive the exhaust grille assembly 41 to rotate about the Y-axis. When the exhaust assembly 4 is in a first state, the exhaust grille assembly 41 closes the exhaust port 12. When the exhaust assembly 4 is in a second state, the exhaust grille assembly 41 opens the exhaust port 12. When the exhaust grille assembly 41 is in a third state, the exhaust grille assembly 41 rotates upward about the Y-axis to a position perpendicular to the nacelle cover 2. It is understood that, referring to... Figure 3 and Figure 8 As shown, the air outlet assembly 4 includes an air outlet grille assembly 41 and an air outlet drive component 43. The rear end of the air outlet grille assembly 41 is hinged to the hood 2. The air outlet grille assembly 41 can rotate along the Y-axis. The air outlet drive component 43 is connected to the air outlet grille assembly 41. The air outlet drive component 43 pushes or pulls the air outlet grille assembly 41, thereby realizing the rotation of the air outlet grille assembly 41, and thus realizing the switching of the air outlet assembly 4 between the first state, the second state, and the third state. Thus, by setting the air outlet drive component 43, the state switching of the air outlet assembly 4 is realized, thereby providing active air brake assist function. Furthermore, since the vertically erected air outlet grille assembly 41 will drastically change the airflow field above the hood and enhance the air pressure at the front of the vehicle, it will actively increase the downforce at the front of the vehicle and improve high-speed driving stability. When deceleration is required (such as high-speed braking), the erected air outlet assembly 4 can increase air resistance, acting as an air brake, thus improving braking efficiency and safety.

[0026] like Figure 1 and Figure 2 As shown, this is the first state, with the air outlet 12 closed and the air outlet grille assembly 41 covering the position of the air outlet 12; as Figure 3 and Figure 4 As shown, in the second state, the air outlet 12 is open, and the air outlet grille assembly 41 can rotate either along the axis in the X direction or along the axis in the Y direction; as Figure 8 and Figure 9 As shown, in the third state, the air outlet 12 is open, and the air outlet grille assembly 41 rotates upward and stands vertically along the axis in the Y direction.

[0027] In some embodiments, by setting the air outlet drive component 43, multi-level control is also realized. For example, when the air outlet grille assembly 41 rotates 0°, the air outlet 12 is closed, which reduces the overall vehicle drag coefficient. When the air outlet grille assembly 41 rotates 30°-60°, the air outlet 12 is partially opened for ventilation and heat dissipation. When the air outlet grille assembly 41 rotates 90°, the air outlet 12 is fully opened, realizing active aerodynamic control.

[0028] In some embodiments of this application, the exhaust assembly 4 further includes a transmission member 42, one end of which is connected to the exhaust drive member 43, and the other end of which is connected to the other end of the exhaust grille assembly 41. The transmission member 42 drives the exhaust grille assembly 41 to rotate vertically around the Y-axis. It is understood that the exhaust drive member 43 provides a power source for the rotation of the exhaust grille assembly 41, and the transmission member 42 connects the exhaust drive member 43 and the exhaust grille assembly 41 to transmit power. The transmission member 42 can transmit the motion of the exhaust drive member 43 and convert it into the vertical rotation motion of the exhaust grille assembly 41 around the Y-axis. Therefore, the transmission is precise and the response is rapid, improving the stability and reliability of the exhaust assembly 4. The simple structure reduces the failure rate of the exhaust assembly 4 during the switching between the first, second, and third states.

[0029] like Figure 3 As shown, when switching from the first state to the second state, the exhaust drive 43 drives the transmission 42 to shorten, and the transmission 42 drives the exhaust grille assembly 41 to rotate downward, thereby opening the exhaust port 12; as Figure 9 As shown, when switching from the second state to the third state, the exhaust drive 43 drives the transmission 42 to extend, and the transmission 42 drives the exhaust grille assembly 41 to rotate upward along the Y-axis, thereby making the exhaust grille assembly 41 stand vertically; when switching from the third state to the first state or the second state, the exhaust drive 43 drives the transmission 42 to shorten, and the transmission 42 drives the exhaust grille assembly 41 to rotate downward.

[0030] In some embodiments of this application, the air vent grille assembly 41 includes: a plurality of air vent grilles 411 and an air vent frame. The plurality of air vent grilles 411 are arranged in a left-right direction to close the air vent 12 in a first state. The front and rear ends of the plurality of air vent grilles 411 are connected to the air vent frame. The plurality of air vent grilles 411 are rotatable about an axis in the X direction, and the air vent frame is rotatably connected to the hood 2 about an axis in the Y direction. It is understood that the plurality of air vent grilles 411 are arranged along the left-right direction (X direction) of the vehicle, each air vent grille 411 is rotatable about its own X-axis (i.e., the axis in the front-rear direction), and the air vent frame itself is rotatable about an axis in the Y direction, so that the air vent grille assembly 41 can rotate upward or downward as a whole, thereby changing the direction of airflow or completely closing / opening the air vent 12. Therefore, the air vent grille assembly 41 has a simple structure and ingenious design. By cleverly utilizing space, it achieves complex multi-dimensional regulation without increasing the volume. At the same time, it combines traditional airflow channel 1 management with modern active aerodynamic control, which can reduce wind resistance, improve cooling efficiency, and enhance the dynamic stability of the vehicle.

[0031] Reference Figure 4As shown, in the second state, the air vent grille assembly 41 can open the air vent 12 by rotating the air vent grille assembly 41 upward along the Y-axis, thereby opening the air vent 12; as Figure 5 As shown, the air vent assembly 41 can also open the air vent 12 by rotating multiple air vent plates 411 of the air vent assembly 41 around the axis in the X direction.

[0032] In some embodiments of this application, the plurality of exhaust grilles 411 include an active exhaust plate and an active exhaust plate, and the exhaust grille assembly 41 further includes an exhaust grille driver. The active exhaust plate is driven to the exhaust grille driver to drive the passive exhaust plate to rotate about its own axis in the X direction. It can be understood that the active exhaust plate is driven to the exhaust grille driver, and the active exhaust plate is driven to the exhaust passive plate, thereby realizing the coordinated rotation of the plurality of exhaust grilles 411 about their own axes in the X direction.

[0033] In some embodiments of this application, the air intake assembly 3 includes an air intake grille assembly 31 and an air intake drive member 32. One end of the air intake grille assembly 31 in the vertical direction is connected to the front bumper. The air intake drive member 32 is drively connected to the air intake grille assembly 31 to drive the air intake grille assembly 31 to rotate about the Y-axis. When the air intake assembly 3 is in a first state, the air intake grille assembly 31 closes the air intake port 11. When the air intake assembly 3 is in a second state, the air intake grille assembly 31 opens the air intake port 11. When the air intake assembly 3 is in a third state, the air intake grille assembly 31 opens the air intake port 11. It can be understood that, referring to... Figure 8 As shown, the air intake assembly 3 includes an air intake grille assembly 31 and an air intake drive component 32. The lower end of the air intake grille assembly 31 is hinged to the front bumper. The air intake grille assembly 31 can rotate along the Y-axis. The air intake drive component 32 is connected to the air intake grille assembly 31. The air intake drive component 32 pushes or pulls the air intake grille assembly 31, thereby realizing the rotation of the air intake grille assembly 31 and thus enabling the air intake assembly 3 to switch between a first state, a second state, and a third state. Therefore, by setting the air intake drive component 32, the state switching of the air intake assembly 3 is realized. When the air intake assembly 3 is in the first state, wind resistance is optimized, reducing the overall vehicle drag coefficient. When the air intake assembly 3 is in the second state, heat dissipation efficiency is improved, effectively ensuring the thermal management of the powertrain system.

[0034] In some embodiments, by setting the air intake drive component 32, multi-level control is also realized. For example, when the air intake grille assembly 31 rotates 0°, the air intake 11 is closed, which reduces the overall vehicle drag coefficient. When the air intake grille assembly 31 rotates 30°-60°, the air intake 11 is partially opened for ventilation and heat dissipation. When the air intake grille assembly 31 rotates 90°, the air intake 11 is fully opened, realizing active aerodynamic control.

[0035] Furthermore, the air intake grille assembly 31 and the air exhaust grille assembly 41 work together to achieve better adjustment of the vehicle's overall wind resistance, better heat dissipation efficiency, and improved braking performance and safety.

[0036] In some embodiments of this application, the air intake grille assembly 31 includes: a plurality of air intake grille plates 311 and an air intake frame. The plurality of air intake grille plates 311 are arranged in a left-right direction to close the air intake 11 in a first state. The upper and lower ends of the plurality of air intake grille plates 311 are connected to the air intake frame. The plurality of air intake grille plates 311 are rotatable about an axis in the Z direction, and the air intake frame is rotatably connected to the front bumper about an axis in the Y direction. It is understood that, as Figure 9 As shown, multiple air intake grilles 311 are arranged along the left-right direction (X direction) of the vehicle. Each air intake grille 311 can rotate around its own Z-axis (i.e., the vertical axis), and the air intake frame itself can rotate around the Y-axis, allowing the air intake grille assembly 31 to rotate upwards or downwards as a whole, thereby changing the airflow direction or completely closing / opening the air intake 11. Thus, the air intake grille assembly 31 has a simple structure and ingenious design, achieving complex multi-dimensional control without increasing additional volume. It combines traditional airflow channel 1 management with modern active aerodynamic control, and in conjunction with the exhaust assembly 4, it can enhance the vehicle's dynamic stability while reducing wind resistance and improving cooling efficiency.

[0037] Reference Figure 8 As shown, in the second state, the air intake grille assembly 31 can open the air intake 11 by rotating the air intake grille assembly 31 upward along the Y-axis, thereby opening the air intake 11; as Figure 9 As shown, the air intake grille assembly 31 can also open the air intake 11 by rotating multiple air intake grilles 311 around the axis in the X direction.

[0038] In some embodiments of this application, the plurality of air intake grilles 311 include an active air intake plate and a driven air intake plate. The air intake grille assembly 31 also includes an air intake grille drive member. The active air intake plate is driven to the air intake grille drive member to drive the driven air intake plate to rotate about its axis in the Z direction. It can be understood that the active air intake plate is driven to the air intake grille drive member, and the active air intake plate is driven to the air intake driven plate, thereby realizing the coordinated rotation of the plurality of air intake grilles 311 about their own axes in the X direction.

[0039] In some embodiments of this application, the vehicle front structure 100 further includes a control module, with at least one of the engine compartment cover 2, the air intake assembly 3, and the air exhaust assembly 4 electrically connected to the control module. It is understood that the control module receives real-time data from various vehicle sensors, determines the appropriate state based on a preset strategy or intelligent algorithm, then sends control signals to the air intake assembly 3 and the air exhaust assembly 4 to drive them to perform corresponding actions, and finally receives feedback signals from the actuators, thus achieving closed-loop control and ensuring that the actions are performed correctly. Therefore, by electrically connecting the air intake assembly 3 and the air exhaust assembly 4 to the control module, coordinated actions of the air intake assembly 3 and the air exhaust assembly 4 are achieved, enabling automatic state switching and adaptive adjustment of the vehicle front structure 100.

[0040] Furthermore, the embodiments of this application can improve the response speed and shorten the response time by using PID algorithm and multi-sensor fusion, ensuring rapid switching of states in emergency situations and ensuring that the vehicle always maintains optimal aerodynamic performance under various operating conditions.

[0041] In other embodiments, the vehicle front structure 100 also has a switchable fourth state, in which the air inlet 11 is closed and the air outlet 12 is open, which allows hot air in the engine compartment to be discharged smoothly, forming a "chimney effect" and enhancing natural convection cooling.

[0042] The vehicle according to an embodiment of this application includes the vehicle front structure 100 of the above embodiment.

[0043] The vehicle according to the embodiments of this application, by setting the front structure 100 of the above embodiments, has the same technical effect, that is, by realizing the coordinated active control of the air intake 11 and the air outlet 12 on the hood, the fuel economy of the vehicle during high-speed cruising or the driving range of pure electric vehicles can be improved, achieving energy saving and emission reduction. It can also enhance the air pressure at the front of the vehicle, thereby actively increasing the downforce at the front of the vehicle, enhancing the grip of the front wheels, effectively suppressing the "floating" phenomenon of the front of the vehicle during high-speed driving, improving high-speed driving stability, and improving the stability and steering accuracy of the vehicle at high speed.
