Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to an active grille shutter assembly and a vehicle. BACKGROUND

[0002] Both active grille shutters and active air dams are important components for regulating ambient airflow for motor vehicles. Among them, the active grille shutter assembly can be opened when the vehicle engine needs to be cooled, improving the cooling speed of the engine, and closed when the engine does not need to be cooled, which can quickly heat the engine, improve engine efficiency, reduce exhaust emissions, and also reduce wind resistance to achieve the purpose of saving fuel and reducing consumption. Active air dams can be used to control the flow of air relative to the vehicle in speed to improve the vehicle's dynamic performance and maneuverability, and to improve the damping coefficient of the vehicle body, or to generate a downward force on it to improve the stability of the vehicle.

[0003] Generally, the active grille shutter assembly and the active air dam are both arranged at the front end of the vehicle. Among them, the active grille shutter assembly and the active air dam both adopt a flip-up motion, and the flip-up angle of the active grille shutter assembly and the active air dam is adjusted by separate control systems to regulate the ambient airflow.

[0004] However, the space at the front end of the vehicle is limited, and the independent control systems of the active grille shutter assembly and the active air dam occupy a large space, thereby causing the problem that the active grille shutter assembly and the active air dam are difficult to arrange. SUMMARY

[0005] The embodiments of the present application provide an active grille shutter assembly and a vehicle to solve the problem that the active grille shutter assembly and the active air dam of the existing vehicle are difficult to arrange.

[0006] The first aspect of the present application provides an active grille shutter assembly applied to a vehicle, wherein the vehicle includes a vehicle body and a grille opening arranged on the vehicle body. The active grille shutter assembly includes a first structure and a controller. The first structure is movably connected to the vehicle body in the vertical direction, and the controller is connected to the first structure. The controller is used to control the first structure to move relative to the vehicle body in the vertical direction. The first structure includes a first state and a second state. The first structure is used to block airflow from entering the vehicle body through the grille opening in the first state, and the first structure is also used to block airflow from passing through the bottom of the vehicle body in the second state.

[0007] The active air intake grille assembly in the embodiment of the present application can move in the vertical direction relative to the vehicle body, that is, the first structure can move up and down relative to the vehicle body, and when the first structure is in the first state, it can be used to block the airflow from the grille opening into the vehicle body, so that the part of the first structure in the first state can play the role of the air intake grille, block the airflow into the vehicle body, and have a heat preservation effect on the engine, thereby quickly heating the engine, improving the engine efficiency, reducing exhaust emission, and reducing wind resistance to achieve the purpose of saving fuel and reducing consumption.

[0008] When the first structure is in the second state, it can be used to block the airflow from the bottom of the vehicle body, so that the part of the first structure in the second state can play the role of the air dam, improve the vehicle dynamics and operability, and improve the damping coefficient of the vehicle body or generate a downward force thereon to improve the stability of the vehicle.

[0009] That is, the first structure can be used as an air intake grille and an air dam, and is simple to control. Therefore, the active air intake grille assembly in the embodiment of the present application has simple structure, small size and low cost, can reduce the installation space and facilitate assembly.

[0010] In one possible implementation, when the first structure is in the first state, at least part of the structure of the first structure is located in the grille opening and is used to block at least part of the grille opening. When the first structure is in the second state, at least part of the structure of the first structure extends out of the bottom of the vehicle body.

[0011] When the first structure is in the first state, at least part of the structure of the first structure is located in the grille opening, so that this part of the first structure located in the grille opening can block at least part of the grille opening, so that the first structure can block the airflow from the grille opening into the vehicle body. When the first structure is in the second state, at least part of the structure of the first structure extends out of the bottom of the vehicle body, so that this part of the first structure extending out of the bottom of the vehicle body can block the airflow at the bottom of the vehicle body, that is, block the airflow into the bottom of the vehicle body, so that the air pressure at the bottom of the vehicle body is less than the air pressure outside the vehicle body, so that the downward force of the vehicle body is greater, and the stability of the vehicle body is improved.

[0012] In one possible implementation, a monitoring device is further included. The monitoring device is electrically connected with the controller, and is used to collect driving parameter information of the vehicle. The controller is used to control the first structure to move in the vertical direction relative to the vehicle body according to the driving parameter information.

[0013] By providing a monitoring device, the controller can control the movement of the first structural member using the vehicle driving parameter information collected by the monitoring device. In other words, the controller can control the movement direction of the first structural member using the vehicle driving parameter information collected by the monitoring device. For example, when the first structural member is required to function as an air intake grille, the first structural member can be controlled to move upward to block the grille opening. When the first structural member is required to function as an air dam, the first structural member can be controlled to move downward so that part of the first structural member extends beyond the bottom of the vehicle body, thereby blocking airflow from entering the bottom of the vehicle body.

[0014] In one possible implementation, a drive assembly is further included, wherein the first structural member is connected to the drive assembly. The drive assembly is electrically connected to the controller, and the controller is configured to control the drive assembly to drive the first structural member to move vertically relative to the vehicle body.

[0015] By providing a driving assembly, a driving force is provided for the movement of the first structural member, so as to drive the first structural member to move in a vertical direction. By electrically connecting a controller to the driving assembly, the driving assembly is controlled by the controller.

[0016] In a possible implementation, the driving assembly includes a guide rail and an actuator, wherein the first structural member is movably connected to the guide rail, and the actuator is used to drive the first structural member to move in a vertical direction along the guide rail.

[0017] By providing a drive assembly including a guide rail and an actuator, the first structural member can be movably connected to the guide rail. Thus, when the first structural member moves in the vertical direction, it can move along the guide rail, thereby preventing the first structural member from shaking during vertical movement and improving the stability of the first structural member during movement. By providing an actuator, a driving force can be provided for the movement of the first structural member.

[0018] In a possible implementation, the actuator is a motor.

[0019] In one possible implementation, a second structural member is further included, wherein in the vertical direction, the first structural member and the second structural member are relatively arranged on both sides of the grille opening, and the first structural member is located between the grille opening and the bottom of the vehicle body, and the second structural member is located between the grille opening and the top of the vehicle body.

[0020] By setting a second structural member and arranging the first structural member and the second structural member relatively on both sides of the grille opening, the opening or closing of the grille opening can be controlled jointly by the first structural member and the second structural member. Compared with controlling the opening or closing of the grille opening only by the first structural member, the flexibility of the grille opening control can be improved.

[0021] In a possible implementation, the second structure is connected with a controller, and the controller is configured to control the second structure to move in the vertical direction relative to the vehicle body.

[0022] The second structure is connected with the controller, so that the controller can control the second structure to move in the vertical direction.

[0023] In a possible implementation, the second structure includes a third state and a fourth state. When the second structure is in the third state, at least part of the second structure is located in the grille opening and is configured to block at least part of the grille opening to prevent air flow from entering the vehicle body through the grille opening. When the second structure is in the fourth state, the second structure is located outside the grille opening.

[0024] When the second structure is in the third state, at least part of the second structure is located in the grille opening, so that the part of the second structure located in the grille opening can be used to prevent air flow from entering the vehicle body through the grille opening. In this way, the part of the second structure in the third state can function as an air inlet grille to prevent air flow from entering the vehicle body, thereby keeping the engine warm, quickly heating the engine, improving engine efficiency, reducing exhaust emission, reducing wind resistance, and achieving the purpose of saving fuel and reducing consumption. When the second structure is in the fourth state, the second structure is arranged outside the grille opening, so that the grille opening is open, which is conducive to engine heat dissipation of the vehicle.

[0025] In a possible implementation, the first structure is connected with a first driving assembly, and the second structure is connected with a second driving assembly. The first driving assembly and the second driving assembly are both electrically connected with the controller, and the controller is configured to control the first driving assembly to drive the first structure to move in the vertical direction relative to the vehicle body. The controller is also configured to control the second driving assembly to drive the second structure to move in the vertical direction relative to the vehicle body.

[0026] The first driving assembly and the second driving assembly are provided to provide driving force for movement of the first structure and the second structure, so as to drive the first structure and the second structure to move in the vertical direction. The controller is electrically connected with the first driving assembly and the second driving assembly, so that the controller can control the first driving assembly and the second driving assembly.

[0027] In a possible implementation, the first driving assembly comprises a first guide rail and a first actuator, and the second driving assembly comprises a second guide rail and a second actuator. The first structural member is movably connected to the first guide rail, and the first actuator is configured to drive the first structural member to move in the vertical direction along the first guide rail. The second structural member is movably connected to the second guide rail, and the second actuator is configured to drive the second structural member to move in the vertical direction along the second guide rail.

[0028] By arranging the first driving assembly to comprise the first guide rail and the first actuator, the first structural member can be movably connected to the first guide rail, so that when the first structural member moves in the vertical direction, the first structural member can move along the first guide rail, and the first structural member can be prevented from shaking when moving in the vertical direction, thereby improving the stability of the first structural member when moving.

[0029] By arranging the second driving assembly to comprise the second guide rail and the second actuator, the second structural member can be movably connected to the second guide rail, so that when the second structural member moves in the vertical direction, the second structural member can move along the second guide rail, and the second structural member can be prevented from shaking when moving in the vertical direction, thereby improving the stability of the second structural member when moving.

[0030] In a possible implementation, the first actuator and the second actuator are both motors.

[0031] The second aspect of the present application provides a vehicle comprising a vehicle body and the active grille shutter assembly of any one of the first aspect.

[0032] The vehicle in the embodiments of the present application comprises the active grille shutter assembly of the first aspect, and the active grille shutter assembly of the first aspect has simple structure, small size and low cost, so that the installation space can be reduced, the assembly is facilitated, and the assembly difficulty of the active grille shutter is reduced, and the cost of the vehicle is reduced.

[0033] In a possible implementation, the vehicle body comprises a grille opening and an engine compartment, and the grille opening and the engine compartment are in communication. The active grille shutter assembly comprises a first structural member, and the first structural member is located between the grille opening and the engine compartment.

[0034] By arranging the first structural member to be located between the grille opening and the engine compartment, the first structural member can be arranged in the interior of the vehicle body, the appearance of the vehicle body can be improved, and the user experience can be improved.

[0063] To make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0064] The conventional active grille shutter and active air dam are usually two separate components. The active grille shutter usually adopts a flap type movement, needs a set of motor to control its movement, and still has grille blades after opening, which reduces the utilization rate of the grille opening area and reduces the heat dissipation efficiency through the vehicle engine. The active air dam usually adopts a flip type movement, and the curved air dam needs to be split into a three-section structure, each section needs a set of motor to realize its movement, which needs a larger space.

[0065] However, the space of the front end of the vehicle is limited, which makes it difficult to arrange the active grille shutter and the active air dam.

[0066] In order to solve the above-mentioned technical problems, the present application provides an active air intake grille assembly and a vehicle. The active air intake grille assembly is configured by setting a first structural member, and the first structural member is configured to be movable in a vertical direction. When the first structural member is in a first state, it also serves as an air intake grille. When the first structural member is in a second state, it can serve as an active air dam, thereby simplifying the structure of the active air intake grille assembly, reducing the occupied space, and facilitating layout.

[0067] The active air intake grille assembly and vehicle provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0068] Figure 1 A schematic structural diagram of a vehicle provided in an embodiment of the present application.

[0069] For ease of description, in this embodiment of the present application, the height direction of the vehicle 100 is referred to as the z-direction, the width direction of the vehicle 100 is referred to as the x-direction, and the length direction of the vehicle 100 is referred to as the y-direction. The height direction of the vehicle 100 is the vertical direction, the axial direction of the wheel 30 is the same as the width direction of the vehicle 100, and the direction from the front to the rear of the vehicle is the length direction of the vehicle 100.

[0070] The embodiment of the present application provides a vehicle 100, such as Figure 1 As shown, the vehicle 100 may include a vehicle body 20 and wheels 30. The wheels 30 are disposed at the bottom 22 of the vehicle body and are used to support the vehicle body 20. A hood 23 is disposed at the front of the vehicle body 20, and an engine compartment 24 is disposed below the hood 23 (see FIG. Figure 2 As shown in FIG, the engine assembly of the vehicle 100 can be arranged in the engine compartment 24. A grille opening 21 is provided at the front end of the vehicle body 20, and the grille opening 21 and the engine compartment 24 are in communication.

[0071] For example, Figure 2 As shown, the engine compartment 24 is disposed below the hood 23 of the vehicle body 20, a grille opening 21 may be disposed at the front end of the vehicle body 20, and an active air intake grille assembly 10 may be disposed inside the grille opening 21. The active air intake grille assembly 10 may, in some cases, block the grille opening 21 to prevent airflow from entering the engine compartment 24 through the grille opening 21, or may, in some cases, open the grille opening 21 to allow airflow to enter the engine compartment 24 through the grille opening 21.

[0072] By arranging the first structural member 11 between the grille opening 21 and the engine compartment 24 , the first structural member 11 can be arranged inside the vehicle body 20 , thereby improving the appearance of the vehicle body 20 and enhancing the user experience.

[0073] It should be noted that the active air intake grille assembly 10 can be used to block the grille opening 21, wherein, when the active air intake grille assembly 10 completely blocks the grille opening 21 (such as Figure 1 As shown), the grille opening 21 is in a closed state. At this time, the airflow can be prevented from entering the engine compartment 24 from the grille opening 21, which can keep the engine warm, thereby quickly heating the engine, improving engine efficiency, reducing exhaust emissions, and reducing wind resistance, thereby achieving the purpose of saving fuel and reducing consumption.

[0074] When the active air intake grille assembly 10 partially blocks the grille opening 21, the grille opening 21 is in a partially closed state. At this time, it can also block part of the airflow from the grille opening 21 into the engine compartment 24, and can also allow part of the airflow to enter the engine compartment 24 from the grille opening 21. This can have a certain heat dissipation effect on the engine, prevent the engine temperature from being too high and causing abnormalities, and thus protect the engine.

[0075] When the active air intake grille assembly 10 has no blocking effect on the grille opening 21, the grille opening 21 is in an open state (eg, Figure 2 As shown, airflow is allowed to enter the engine compartment 24 through the grille opening 21, which can dissipate heat from the engine, preventing abnormal engine temperatures from overheating and thus protecting the engine. Furthermore, the heat dissipation efficiency is higher than when the grille opening 21 is partially closed.

[0076] In addition, the active grille assembly 10 can also be used as an air dam for the vehicle 100. When the active grille assembly 10 extends beyond the bottom of the vehicle body 20, the air dam 111 is in an open state, thereby blocking airflow from passing through the bottom of the vehicle body 20. When the active grille assembly 10 is located within the bottom of the vehicle body 20, the air dam 111 is in a closed state.

[0077] The active air intake grille assembly 10 provided in an embodiment of the present application is described below with reference to the accompanying drawings.

[0078] The present application embodiment provides an active air intake grille assembly 10, which is applied to a vehicle 100, such as Figure 3 As shown, the active air intake grille assembly 10 may include a first structural member 11 and a controller 13. The first structural member 11 is vertically movable with respect to the vehicle body 20. The controller 13 is connected to the first structural member 11 and is configured to control the vertical movement of the first structural member 11 relative to the vehicle body 20. The first structural member 11 may have a first state and a second state. In the first state, the first structural member 11 is configured to block airflow from entering the vehicle body 20 through the grille opening 21. In the second state, the first structural member 11 is configured to block airflow from passing through the bottom 22 of the vehicle body.

[0079] It should be noted that in the embodiments of the present application, the vertical direction refers to the height direction of the vehicle 100, which can be perpendicular to the horizontal plane, and can also be at an angle with the horizontal plane. Wherein, the first structure 11 moves in the vertical direction relative to the vehicle body 20, which means that the first structure 11 can move up and down in space. For example, when the first structure 11 is arranged to be inclined relative to the horizontal plane, the first structure 11 can move in the vertical direction relative to the vehicle body 20, which means that the first structure 11 moves up and down along its own inclined direction. Wherein, the up and down direction in the embodiments of the present application is the same as the up and down direction of the vehicle 100, wherein the top of the vehicle 100 is located at the upper side, and the wheels 30 of the vehicle 100 are located at the lower side.

[0080] As shown in the example, Figure 3 When the first structure 11 is in the first state, at least part of the structure of the first structure 11 is located in the grid opening 21 and is used to block at least part of the grid opening 21. As shown in the example, Figure 4 When the first structure 11 is in the second state, at least part of the structure of the first structure 11 extends out of the bottom 22 of the vehicle body, and the air dam 111 is in the open state.

[0081] The active air inlet grille assembly 10 in the embodiments of the present application can move the first structure 11 in the vertical direction relative to the vehicle body 20, that is, the first structure 11 can move up and down relative to the vehicle body 20, and when the first structure 11 is in the first state, it can be used to block the airflow from the grid opening 21 into the vehicle body 20, so that the part of the structure of the first structure 11 in the first state can play the role of the air inlet grille, block the airflow into the vehicle body 20, and play the role of heat preservation for the engine, thereby quickly heating the engine, improving the engine efficiency, reducing exhaust emission, and reducing wind resistance to achieve the purpose of saving oil and reducing consumption.

[0082] When the first structure 11 is in the second state, it can be used to block the airflow from the bottom 22 of the vehicle body, so that the part of the structure of the first structure 11 in the second state can play the role of the air dam, improve the dynamic performance and operability of the vehicle 100, and improve the damping coefficient of the vehicle, or generate a downward force thereon to improve the stability of the vehicle 100.

[0083] That is, the first structure 11 can be used as an air inlet grille and an air dam, and is simple to control. Therefore, the active air inlet grille assembly 10 in the embodiments of the present application has simple structure, small size and low cost, can reduce the installation space and facilitate assembly.

[0084] It should be noted that when the first structure 11 is in the first state, the grid opening 21 is in a partially closed state or a closed state, at which time the airflow can be blocked from entering the vehicle body 20 from the grid opening 21. When the first structure is in the second state, the air dam 111 is in an open state (as shown in Figure 4

[0085] By locating at least part of the first structure 11 within the grid opening 21 when the first structure 11 is in the first state, the part of the first structure 11 located within the grid opening 21 can block at least part of the grid opening 21, so that the first structure 11 can block the airflow from entering the vehicle body 20 from the grid opening 21. By extending at least part of the first structure 11 outside the bottom 22 of the vehicle body when the first structure 11 is in the second state, the part of the first structure 11 extending outside the bottom 22 of the vehicle body can block the airflow at the bottom of the vehicle body 20, that is, block the airflow from entering the bottom of the vehicle body 20, so that the air pressure at the bottom of the vehicle body 20 is less than the air pressure outside the vehicle body 20, so that the downward pressure of the vehicle body 20 is greater, improving the stability of the vehicle body 20.

[0086] It should be noted that when the first structure 11 is in the second state, the length of the first structure 11 extending out of the bottom of the vehicle body 20 is not limited, and can be set according to the specific vehicle model, which is not further limited in the embodiments of the present application.

[0087] For example, the first structure 11 can be a plate structure, and the size of the plate structure in the width direction of the vehicle 100 is greater than the size of the grid opening 21 in the width direction of the vehicle 100, so that the plate structure can block at least part of the grid opening 21 when the plate structure is in the first state.

[0088] For example, in the width direction of the vehicle 100, the first structure 11 extends from the center of the grid opening 21 to both ends, and the first structure 11 is symmetric about the center line of the grid opening 21. To ensure that the airflow entering the vehicle body 20 from the grid opening 21 is relatively uniform in the width direction of the vehicle 100, which can improve the stability of the vehicle 100 during driving.

[0089] As Figure 5 As shown in some embodiments, the active air intake grille assembly 10 can further include a monitoring device 14. The monitoring device 14 is electrically connected to the controller 13, and the monitoring device 14 is used to collect driving parameter information of the vehicle 100, and the controller 13 is used to control the first structure 11 to move in the vertical direction relative to the vehicle body 20 according to the driving parameter information.

[0090] ​For example, the driving parameter information of the vehicle 100 can include a driving speed of the vehicle 100, a temperature of an engine of the vehicle 100, etc. In the embodiments of the present application, the driving parameter information of the vehicle 100 is not limited further. It should be noted that when the driving speed of the vehicle 100 is high, the temperature of the engine of the vehicle 100 is also high. When the vehicle 100 is static or drives at a low speed, the temperature of the engine of the vehicle 100 is low.

[0091] For example, the monitoring device 14 can include a speed sensor and a temperature sensor. In the embodiments of the present application, the specific structure of the monitoring device 14 is not limited further.

[0092] It should be noted that the controller 13 controls the first structure 11 to move in the vertical direction according to the driving parameter information of the vehicle 100, which is not limited to switching the first structure 11 between the first state and the second state.

[0093] In some embodiments, the first structure 11 can include more states. For example, the first state of the first structure 11 further includes a partial blocking state and a full blocking state, and the first structure 11 can further include an intermediate state. When the first structure 11 is in the intermediate state, the first structure 11 is located between the grid opening 21 and the bottom 22 of the vehicle body, at this time, the grid opening 21 is in an open state, and the air dam 111 is in a retracted state. The controller 13 can be configured to switch the first structure 11 between the partial blocking state, the full blocking state, the intermediate state and the second state according to the driving parameter information of the vehicle 100.

[0094] It should be noted that, as shown in Figure 5 The air dam 111 is a part of the first structure 11. When the first structure 11 extends beyond the bottom of the vehicle body 20, the part of the first structure 11 extending beyond the bottom of the vehicle body 20 is the air dam 111.

[0095] Some examples of the controller 13 controlling the first structure 11 according to the driving parameter information of the vehicle 100 are described in detail below.

[0096] In some embodiments, when the driving speed of the vehicle 100 is greater than a first preset threshold, the controller 13 controls the first structure 11 to be in the second state. At this time, it can be considered that the air dam 111 is in an open state, and the part of the first structure 11 extending beyond the bottom of the vehicle body 20 can block the airflow passing through the bottom 22 of the vehicle body 20, so that the pressure on the bottom of the vehicle body 20 is less than the outside of the vehicle body 20, thereby increasing the pressure of the vehicle body 20 and improving the grip effect of the vehicle 100, thereby improving the stability of the vehicle 100.

[0097] For example, the first preset threshold can be any value in 120-160 km / h.

[0098] When the driving speed of the vehicle 100 is less than the first preset threshold, the air dam 111 is not needed to increase the grip of the vehicle 100, and thus the first structure 11 can be adjusted to a state other than the second state. That is, any state in which the first structure 11 does not extend beyond the bottom of the vehicle body 20. Exemplarily, the first structure 11 can be adjusted to the first state or a neutral state. In the embodiments of the present application, no further limitation is made.

[0099] Exemplarily, when the temperature of the engine of the vehicle 100 is less than the second preset threshold, the engine does not need to be cooled, and at this time, the controller 13 can control the first structure 11 to be in the first state. It should be noted that when the first structure 11 is in the first state, the grille opening 21 is in a partially closed state or a closed state. That is, when the temperature is low, the grille opening 21 can be closed or partially closed, thereby playing a role in keeping the engine warm.

[0100] When the temperature of the engine of the vehicle 100 is greater than the second preset threshold, the engine needs to be cooled, and the controller 13 can control the first structure 11 to partially block or not to block the grille opening 21, so as to improve the cooling effect of the engine.

[0101] It should be noted that in the embodiments of the present application, no further limitation is made on the specific manner in which the controller 13 controls the first structure 11 to move in the vertical direction relative to the vehicle body 20 according to the driving parameter information of the vehicle 100. In addition, no further limitation is made on the specific values of the first preset threshold and the second preset threshold.

[0102] By providing the monitoring device 14, the controller 13 can control the movement of the first structure 11 according to the driving parameter information of the vehicle 100 collected by the monitoring device 14. That is, the controller 13 can control the moving direction of the first structure 11 according to the driving parameter information of the vehicle 100 collected by the monitoring device 14. For example, when the first structure 11 needs to realize the function of the air intake grille, the first structure 11 can be controlled to move upward to block the grille opening 21. When the first structure 11 needs to realize the function of the air dam, the first structure 11 can be controlled to move downward so that part of the structure of the first structure 11 extends beyond the bottom of the vehicle body 20, thereby blocking the airflow from entering the bottom of the vehicle body 20.

[0103] Continuing to refer to Figure 5 The active air intake grille assembly 10 provided in the embodiments of the present application can further include a driving assembly 15. The first structure 11 is connected with the driving assembly 15. The driving assembly 15 is electrically connected with the controller 13, and the controller 13 is configured to control the driving assembly 15 to drive the first structure 11 to move in the vertical direction relative to the vehicle body 20.

[0104] The driving assembly 15 is arranged to provide driving force for the movement of the first structural member 11, so as to drive the first structural member 11 to move in the vertical direction. The controller 13 is electrically connected with the driving assembly 15, so as to control the driving assembly 15 through the controller 13.

[0105] For example, the driving assembly 15 includes a guide rail 152 and an actuator 151. The first structural member 11 is movably connected with the guide rail 152, and the actuator 151 is configured to drive the first structural member 11 to move in the vertical direction along the guide rail 152.

[0106] By arranging the driving assembly 15 to include the guide rail 152 and the actuator 151, the first structural member 11 can be movably connected with the guide rail 152, so that the first structural member 11 can move along the guide rail 152 when moving in the vertical direction, and the shaking of the first structural member 11 when moving in the vertical direction can be prevented, and the stability of the first structural member 11 during movement can be improved. By arranging the actuator 151, driving force can be provided for the movement of the first structural member 11.

[0107] For example, the guide rail 152 can have a groove structure, and the first structural member 11 can be provided with a protruding structure matched with the groove. When the first structural member 11 is assembled with the guide rail 152, the protruding structure and the groove structure can be matched and connected, so that the first structural member 11 can move in the vertical direction along the guide rail 152.

[0108] It should be noted that the shape of the guide rail 152 includes but is not limited to the groove structure described above, and in other embodiments, the guide rail 152 can also have other structures. In addition, the number of guide rails 152 can be one, two, three or more. When the number of guide rails 152 is more than one, the plurality of guide rails 152 can be arranged at intervals in the x direction, so that the stability of the first structural member 11 during movement can be improved. In the embodiments of the present application, the specific shape and number of guide rails 152 are not limited further.

[0109] For example, the actuator 151 can be an electric motor. Of course, in other embodiments, the actuator 151 can also be a linkage mechanism, an air cylinder, etc. In the embodiments of the present application, the specific structure of the actuator 151 is not limited further.

[0110] In other embodiments, as shown in Figure 6 The active air intake grille assembly 10 further includes a second structural member 12. In the vertical direction, the first structural member 11 and the second structural member 12 are arranged on opposite sides of the grille opening 21, and the first structural member 11 is located between the grille opening 21 and the bottom of the vehicle body 20, and the second structural member 12 is located between the grille opening 21 and the top of the vehicle body 20.

[0111] By setting the second structural member 12 and oppositely setting the first structural member 11 and the second structural member 12 at both sides of the grid opening 21, the opening or closing of the grid opening 21 can be controlled by the first structural member 11 and the second structural member 12 together, which can improve the flexibility of the control of the grid opening 21, compared with only using the first structural member 11 to control the opening or closing of the grid opening 21.

[0112] For example, the second structural member 12 can be a plate structure, and the size of the plate structure in the width direction of the vehicle 100 is greater than the size of the grid opening 21 in the width direction of the vehicle 100, so that the plate structure can block at least part of the grid opening 21 when in the first state.

[0113] In some embodiments, the opposite side of the first structural member 11 and the second structural member 12 can be set as a plane, an arc surface, a jagged surface, etc. In the embodiments of the present application, the specific structure of the first structural member 11 and the second structural member 12 is not limited further.

[0114] For example, the second structural member 12 is connected with the controller 13, and the controller 13 is used to control the second structural member 12 to move in the vertical direction relative to the vehicle body 20. By connecting the second structural member 12 with the controller 13, the controller 13 can control the second structural member 12 to move in the vertical direction.

[0115] Continuing to refer to Figure 6 As shown, the active air intake grille assembly 10 can further include a first driving assembly 16 and a second driving assembly 17. The first structural member 11 is connected with the first driving assembly 16. The second structural member 12 is connected with the second driving assembly 17. The first driving assembly 16 and the second driving assembly 17 are both electrically connected with the controller 13, and the controller 13 is used to control the first driving assembly 16 to drive the first structural member 11 to move in the vertical direction relative to the vehicle body 20. The controller 13 is also used to control the second driving assembly 17 to drive the second structural member 12 to move in the vertical direction relative to the vehicle body 20.

[0116] By setting the first driving assembly 16 and the second driving assembly 17, driving force is provided for the movement of the first structural member 11 and the second structural member 12, so as to drive the first structural member 11 and the second structural member 12 to move in the vertical direction. By electrically connecting the controller 13 with the first driving assembly and the second driving assembly 17, the controller 13 can control the first driving assembly and the second driving assembly 17.

[0117] Exemplarily, the first driving assembly 16 comprises a first guide rail 162 and a first actuator 161, and the second driving assembly 17 comprises a second guide rail 172 and a second actuator 171. The first structural member 11 is movably connected with the first guide rail 162, and the first actuator 161 is configured to drive the first structural member 11 to move in the vertical direction along the first guide rail 162. The second structural member 12 is movably connected with the second guide rail 172, and the second actuator 171 is configured to drive the second structural member 12 to move in the vertical direction along the second guide rail 172.

[0118] By configuring the first driving assembly 16 to comprise the first guide rail 162 and the first actuator 161, the first structural member 11 can be movably connected with the first guide rail 162, so that when the first structural member 11 moves in the vertical direction, it can move along the first guide rail 162, and the first structural member 11 can be prevented from shaking when moving in the vertical direction, thereby improving the stability of the first structural member 11 when moving. By configuring the first actuator 161, driving force can be provided for the movement of the first structural member 11.

[0119] By configuring the second driving assembly 17 to comprise the second guide rail 172 and the second actuator 171, the second structural member 12 can be movably connected with the second guide rail 172, so that when the second structural member 12 moves in the vertical direction, it can move along the second guide rail 172, and the second structural member 12 can be prevented from shaking when moving in the vertical direction, thereby improving the stability of the second structural member 12 when moving. By configuring the second actuator 171, driving force can be provided for the movement of the second structural member 12.

[0120] In a possible implementation, the first actuator 161 and the second actuator 171 are both motors. Of course, in other embodiments, the first actuator 161 and the second actuator 171 can also be linkages, air cylinders, etc., and in the present embodiment, the specific structure of the actuator 151 is not limited further.

[0121] It should be noted that the first driving assembly 16 and the second driving assembly 17 in the present embodiment have the same structure and principle as the driving assembly 15 in the embodiment shown in Figure 5 Therefore, in the present embodiment, the specific structure of the first driving assembly 16 and the second driving assembly 17 can be referred to the description of the driving assembly 15 in the embodiment in Figure 5 In the present embodiment, the specific structure of the first driving assembly 16 and the second driving assembly 17 will not be described further.

[0122] Exemplarily, in the embodiment of the present application, the active air intake grille assembly 10 can further comprise a monitoring device 14. The monitoring device 14 is electrically connected to the controller 13, and the monitoring device 14 is configured to collect driving parameter information of the vehicle 100, and the controller 13 is configured to control the first structural member 11 and the second structural member 12 to move in the vertical direction relative to the vehicle body 20 according to the driving parameter information.

[0123] Exemplarily, the driving parameter information of the vehicle 100 can include the driving speed of the vehicle 100, the temperature of the engine of the vehicle 100, etc., and the driving parameter information of the vehicle 100 is not limited further in the embodiment of the present application.

[0124] In some embodiments, the second structural member 12 can comprise a third state and a fourth state. When the second structural member 12 is in the third state, at least part of the structure of the second structural member 12 is located in the grille opening 21 and is configured to block at least part of the grille opening 21 to block the airflow from the grille opening 21 into the vehicle body 20. When the second structural member 12 is in the fourth state, the second structural member 12 is located outside the grille opening 21.

[0125] By locating at least part of the structure of the second structural member 12 in the grille opening 21 when the second structural member 12 is in the third state, the part of the second structural member 12 located in the grille opening can be used to block the airflow from the grille opening 21 into the vehicle body 20, so that the part of the second structural member 12 in the third state can play the role of the air intake grille to block the airflow into the interior of the vehicle body 20, thereby the engine can be warmed up quickly, the engine efficiency can be improved, the exhaust emission can be reduced, the wind resistance can be reduced, and the purpose of saving oil and reducing consumption can be achieved. When the second structural member 12 is in the fourth state, the second structural member 12 is arranged outside the grille opening 21, so that the grille opening 21 is opened, which is beneficial to the heat dissipation of the engine of the vehicle 100.

[0126] It should be noted that when the controller 13 controls the first structural member 11 and the second structural member 12 to move in the vertical direction according to the driving parameter information of the vehicle 100, it is not limited to switching the first structural member 11 between the first state and the second state and switching the second structural member 12 between the third state and the fourth state.

[0127] In some embodiments, the first structural member 11 can have multiple states. For example, the first state of the first structural member 11 can include a partially blocked state and a fully blocked state. The first structural member 11 can also have an intermediate state. When the first structural member 11 is in the intermediate state, it is located between the grille opening 21 and the bottom 22 of the vehicle body. In this state, the grille opening 21 is open and the air dam 111 is retracted. The controller 13 can be configured to switch the first structural member 11 between the partially blocked state, the fully blocked state, the intermediate state, and the second state based on driving parameter information of the vehicle 100.

[0128] It should be noted that when the second structural member 12 is in the third state, the grille opening 21 is in a partially closed state or a closed state. When the second structural member 12 is in the fourth state, the second structural member 12 has no blocking effect on the grille opening 21. Since the state of the first structural member 11 cannot be determined, the grille opening 21 can be in a partially closed state, a closed state or an open state at this time.

[0129] The following describes an example in which the controller 13 controls the first structural member 11 and the second structural member 12 according to the driving parameter information of the vehicle 100 with reference to the accompanying drawings.

[0130] like Figure 6 As shown, the grille opening 21 is in the open state, and the air dam 111 is in the retracted state. At this time, the first structural member 11 is in the intermediate state, and the second structural member 12 is in the fourth state.

[0131] like Figure 7 As shown, the grille opening 21 is in the closed state and the air dam 111 is in the retracted state. At this time, the first structural member 11 is in the first state and the second structural member 12 is in the third state. In addition, the first structural member 11 blocks a portion of the grille opening 21 and the second structural member 12 blocks another portion of the grille opening 21.

[0132] like Figure 8 As shown, the grille opening 21 is partially closed and the air dam 111 is retracted. At this time, the first structural member 11 is in the intermediate state and the second structural member 12 is in the third state, with the second structural member 12 partially blocking the grille opening 21.

[0133] like Figure 9 As shown, the grille opening 21 is partially closed and the air dam 111 is retracted. At this time, the first structural member 11 is in the first state, the second structural member 12 is in the fourth state, and the first structural member 11 partially blocks the grille opening 21.

[0134] like Figure 10As shown, the grid opening 21 is in the closed state, and the air dam 111 is in the open state. At this time, the first structural member 11 is in the second state, the second structural member 12 is in the third state, and the second structural member 12 completely blocks the grid opening 21.

[0135] As shown, the grid opening 21 is in the open state, and the air dam 111 is in the open state. At this time, the first structural member 11 is in the second state, the second structural member 12 is in the third state, and the second structural member 12 completely blocks the grid opening 21. Figure 11

[0136] For example, when the driving speed of the vehicle 100 is greater than the first preset threshold value, the temperature of the engine of the vehicle 100 is high, and according to the heat dissipation demand of the cooling system of the vehicle 100, the controller 13 can control the first structural member 11 and the second structural member 12 to move to the positions in Figure 6 , Figure 8 , Figure 9 or Figure 11 in the vertical direction.

[0137] For example, when the driving speed of the vehicle 100 is less than the first preset threshold value, the temperature of the engine of the vehicle 100 is low, or when the vehicle 100 is started at extremely low temperature, the battery of the electric vehicle is usually preheated by the heat source (positive temperature coefficient, PTC) or heat pump of the air conditioner, and for the fuel vehicle or hybrid vehicle 100, the engine also needs to be quickly warmed up to preheat the lubricating power system, the vehicle 100 has no heat dissipation demand and needs to be insulated, so in these cases, the controller 13 can control the first structural member 11 and the second structural member 12 to move to the positions in Figure 7 or Figure 10 in the vertical direction.

[0138] For example, when the driving speed of the vehicle 100 is less than the first preset threshold value, a large downward pressure is not needed to stabilize the ground adhesion of the front axle of the vehicle 100, at this time the air dam 111 can be in the retracted state, and the controller 13 can control the first structural member 11 and the second structural member 12 to move to the positions in Figure 6 , Figure 7 , Figure 8 or Figure 9 in the vertical direction, and the positions of the first structural member 11 and the second structural member 12 can also be specifically selected according to the temperature of the engine.

[0139] When the driving speed of the vehicle 100 is greater than the first preset threshold value, the vehicle needs a large downward pressure to obtain additional tire adhesion, at this time the controller 13 can move the first structural member 11 and the second structural member 12 to Figure 10 and Figure 11 ​The first structural member 11 can extend out of the bottom of the vehicle body 20, and the height of the first structural member 11 extending out of the bottom of the vehicle body 20 can be adjusted according to the driving speed of the vehicle 100, so as to obtain different front axle depression force values.

[0140] It should be noted that, in the embodiments of the present application, the control of the height of the first structural member 11 extending out of the bottom of the vehicle body 20 is not limited further.

[0141] It should be noted that, in some embodiments, the first structural member 11 and the second structural member 12 can also be manually controlled to move in the vertical direction according to the needs of the user, and the control mode of the first structural member 11 and the second structural member 12 is not limited further in the embodiments of the present application.

[0142] The vehicle 100 in the embodiments of the present application can reduce the installation space, facilitate assembly, and thus reduce the assembly difficulty of the active air intake grille assembly 10 and the cost of the vehicle 100, because the active air intake grille assembly 10 has simple structure, small volume and low cost.

[0143] It should be noted that the vehicle in the embodiments of the present application can be a family car, or a medium or large car, a bus, etc., and the type of the vehicle is not limited further in the embodiments of the present application.
