Description

Technical Field

[0001] This application relates to the field of automotive parts manufacturing technology, and in particular to an active air intake grille and vehicle. Background Technology

[0002] Active grille technology is an emerging fuel-saving and emission-reducing technology in the automotive industry. It can adjust the airflow entering the engine compartment according to the engine's cooling needs, reducing the resistance generated by redundant air in the internal flow field, thereby improving the vehicle's fuel economy. At the same time, the grille also has the functions of beautifying the vehicle's appearance and protecting debris from entering the engine compartment.

[0003] Currently, active grille shutters on the market are divided into concealed and exposed types. The mainstream style for exposed grilles is the vertical waterfall design. The opening mechanism involves each vertical waterfall blade B rotating inwards along the rotation axis A to open the air intake, or rotating outwards to close the air intake. Please refer to [reference needed]. Figure 16 . Summary of the Invention:

[0004] To address the aforementioned problems in the prior art, this application provides an active air intake grille and vehicle, which has a larger effective air intake area and improves heat dissipation efficiency.

[0005] This application is achieved through the following technical solution:

[0006] An active air intake grille, characterized in that it comprises: a fixed bracket, a linkage bracket, a drive device, a first linkage mechanism, and at least one air intake unit;

[0007] The intake unit includes multiple blades and multiple blade linkage mechanisms;

[0008] The linkage bracket is rotatably connected to the first end of each of the plurality of blade linkage mechanisms, and the second end of each blade linkage mechanism is rotatably connected to the first end of each blade in a one-to-one correspondence; the second end of the blade is rotatably connected to the fixed bracket.

[0009] The first end of the first linkage mechanism is connected to the linkage bracket; the second end of the first linkage mechanism is connected to the drive device.

[0010] The driving device drives the first linkage mechanism to move, the first linkage mechanism drives the linkage bracket to move, the linkage bracket drives the blade linkage mechanism to move, and the blade linkage mechanism drives the first end of the blade to rotate, thereby opening or closing the air intake unit. Furthermore, when the air intake unit is in the open state, at least two blades are not parallel to each other.

[0011] In this application, under the same blade opening angle, compared with the traditional active air intake grille, the effective air intake area of ​​the active air intake grille is significantly increased, improving heat dissipation efficiency. By setting multiple blades, the airflow is distributed among multiple blades with the same blade area, improving the overall air intake unit's load-bearing capacity and reducing damage. By connecting multiple sets of blades to a linkage bracket, the air intake unit opens and closes as the linkage bracket moves along its thickness direction, ensuring the synchronicity of each blade's movement. Furthermore, through ingenious design, a driving device sequentially drives the first linkage mechanism, the linkage bracket, and the blade linkage mechanism, thereby driving at least two non-parallel blades to open and close the air intake unit. This saves internal space, reduces costs, and meets air intake requirements. Compared with the traditional method under the same blade opening angle, it increases the effective air intake area and achieves diverse airflow angles, delivering air to various locations in the vehicle requiring heat dissipation.

[0012] Furthermore, it also includes a second linkage mechanism;

[0013] One end of the second linkage mechanism is fixedly connected to the fixed bracket; the other end of the second linkage mechanism is fixedly connected to the linkage bracket.

[0014] This application sets up a first linkage mechanism and a second linkage mechanism to transmit the force on the first linkage mechanism to the second linkage mechanism. The first linkage mechanism and the second linkage mechanism work together to drive the linkage support to move, ensuring the balance, synchronization and simultaneity of the linkage support during movement, thereby improving the angular synchronization and angular stability when multiple blades rotate.

[0015] Furthermore, the active air intake grille includes a first air intake section and a second air intake section;

[0016] The first air intake and the second air intake are respectively provided with the drive device, the first linkage mechanism and at least one air intake unit;

[0017] The drive unit is electrically connected to the vehicle's controller, which is used to control a single drive unit individually.

[0018] This application divides the entire active air intake grille into at least a first air intake section and a second air intake section. The blade movement direction of the first air intake section and the second air intake section can be controlled separately by an independent drive motor, so that the blade movement direction and rotation angle of the two sections can be the same or different. The opening angle of the blades in the air intake units of the first air intake section and the second air intake section can be set according to the requirements, which has a wide range of applications.

[0019] Furthermore, a rotating shaft is provided at the connection between the blade and the fixed bracket, and the blade can move away from the fixed bracket along the rotating shaft;

[0020] The multiple blades in a single intake unit rotate in different directions.

[0021] This application achieves diverse airflow angles by setting multiple blades and having multiple blades in a single air intake unit rotate in different directions, thereby delivering airflow to various locations in the vehicle that require cooling; and it saves more internal space compared to single-opening or double-opening (i.e., opening in two directions).

[0022] Furthermore, the second end of the blade linkage mechanism is axially connected to the free end of the blade; the connecting end of the blade is axially connected to the fixed bracket.

[0023] Each blade is axially connected to at least one blade linkage mechanism.

[0024] Furthermore, one end of the first linkage mechanism is fixedly connected to the fixed bracket, and the first linkage mechanism drives the linkage bracket to move toward or away from the second end of the blade.

[0025] This application improves the stability of the linkage support movement by fixing the first linkage mechanism to the fixed support, so that when the first linkage mechanism drives the linkage support to move toward or away from the second end of the blade.

[0026] Furthermore, the shape of the blade includes at least one of triangle, trapezoid, and fan shape.

[0027] Furthermore, the fixed bracket is provided with an air intake unit mounting port, and the air intake unit mounting port is provided in a one-to-one correspondence with the air intake unit;

[0028] The shape of the air intake unit mounting port includes at least one of a circle and a polygon, and the plurality of blades are arranged circumferentially along the edge of the air intake unit mounting port.

[0029] This application uses blades with shapes including triangles, trapezoids, and fan shapes, arranged circumferentially along the edge of the air intake unit mounting port. With the same blade opening angle, compared to a traditional active air intake grille, the effective air intake area of ​​this application's active air intake grille is significantly increased, thus improving heat dissipation efficiency.

[0030] This application also provides a vehicle including the active grille shutter as described above. Attached Figure Description

Detailed Implementation

[0049] This application discloses an active air intake grille with a large effective air intake area, which improves heat dissipation efficiency.

[0050] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] It should be noted that in the description of this application, the terms "end," etc., indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the components referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data used can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0052] This application provides an active air intake grille; please refer to [reference needed]. Figure 1-15The system includes: a fixed bracket 1, a linkage bracket 2, a drive device 3, a first linkage mechanism 4, and at least one air intake unit 10; the air intake unit 10 includes multiple blades 6 and multiple blade linkage mechanisms 7; the linkage bracket 2 is rotatably connected to the first end of each blade linkage mechanism 7, and the second end of each blade linkage mechanism 7 is rotatably connected to the first end of each blade 6 in a one-to-one correspondence; the second end of the blade 6 is rotatably connected to the fixed bracket 1; the first end of the first linkage mechanism 4 is connected to the linkage bracket 2; the second end of the first linkage mechanism 4 is connected to the drive device 3; the drive device 3 drives the first linkage mechanism 4 to move, the first linkage mechanism 4 drives the linkage bracket 2 to move, the linkage bracket 2 drives the blade linkage mechanism 7 to move, and the blade linkage mechanism 7 drives the first end of the blade 6 to rotate, so as to open or close the air intake unit 10.

[0053] This application connects to the first linkage mechanism 4 via a drive device 3. Under the driving action of the drive device, the drive device drives the drive shaft 41 of the first linkage mechanism 4 to move, thereby driving the first linkage mechanism 4 to move. One end of the first linkage mechanism 4 is fixedly connected to the linkage bracket 2. During the movement of the first linkage mechanism 4, the first linkage mechanism 4 drives the linkage bracket 2 to move along the thickness direction of the linkage bracket 2. The linkage bracket 2 is rotatably connected to the first end of the blade linkage mechanism 7, the second end of the blade linkage mechanism 7 is rotatably connected to the blade 6, and the blade 6 is rotatably connected to the fixed bracket 1. During the movement of the linkage bracket 2 along the thickness direction of the linkage bracket 2, the linkage bracket 2 drives the blade to rotate through the blade linkage mechanism 7. After the blade rotates, the air intake unit 10 opens, thereby achieving the air intake effect. With the same blade opening angle, compared with the traditional active air intake grille, the effective air intake area of ​​the active air intake grille of this application is significantly increased, which improves the heat dissipation efficiency; and this application is equipped with multiple blades, which distribute the wind force to multiple blades with the same blade area, thereby improving the overall air intake unit 10's load-bearing capacity and making it less prone to damage; this application ensures the synchronicity of the movement of each blade by connecting multiple sets of blades to the linkage bracket, as the linkage bracket moves along the thickness direction of the linkage bracket.

[0054] In some embodiments, one end of the first linkage mechanism 4 is fixedly connected to the fixed bracket 1. By fixing the first linkage mechanism 4 to the fixed bracket 1, the stability of the linkage bracket movement is improved when the first linkage mechanism 4 drives the linkage bracket 2 to move toward or away from the second end of the blade 6.

[0055] In some embodiments, a second linkage mechanism 5 is further included; one end of the second linkage mechanism 5 is fixedly connected to the fixed bracket 1, and the other end of the second linkage mechanism 5 is fixedly connected to the linkage bracket 2. It should be noted that the first linkage mechanism 4 can be arranged in the length direction of the active air intake grille, that is, after the active air intake grille is installed on the vehicle, the first linkage mechanism 4 can be arranged at the bottom of the active air intake grille, and the second linkage mechanism can be arranged in the width direction of the active air intake grille, that is, after the active air intake grille is installed on the vehicle, the first linkage mechanism 4 can be arranged on the side of the active air intake grille. By setting the first linkage mechanism and the second linkage mechanism, the first linkage mechanism drives the second linkage mechanism, and the first linkage mechanism and the second linkage mechanism jointly drive the linkage bracket to move, ensuring the balance, synchronization and simultaneity of the linkage bracket during movement, thereby improving the angular synchronization and angular stability when multiple blades rotate.

[0056] In some embodiments, the active air intake grille includes a first air intake section 11 and a second air intake section 12; the first air intake section 11 and the second air intake section 12 are respectively provided with a drive device 3, a first linkage mechanism 4, and at least one air intake unit 10; the drive device 3 is electrically connected to the vehicle's controller, which is used to control a single drive device 3 individually. This application divides the entire active air intake grille into at least a first air intake section 11 and a second air intake section 12. The blade movement direction of the first air intake section 11 and the second air intake section 12 can be controlled independently by a separate drive motor, so that the blade movement direction and rotation angle of the two sections can be the same or different. The opening angle of the blades in the air intake unit 10 of the first air intake section 11 and the second air intake section 12 can be set according to requirements, making it widely applicable. Preferably, the first air intake section 11 and the second air intake section 12 are also provided with a second linkage mechanism 5.

[0057] In some embodiments, when the intake unit 10 is in the open state, at least two blades 6 are not parallel to each other, so that the orientation of at least two blades 6 is inconsistent. Thus, when the intake unit 10 is in the open state, multiple angles of air intake are achieved by the intake unit 10.

[0058] In some embodiments, the second end of the blade linkage mechanism 7 is axially connected to the free end of the blade 6; the connecting end of the blade 6 is axially connected to the fixed bracket 1; and a single blade 6 is axially connected to at least one blade linkage mechanism 7. The number of blade linkage mechanisms 7 can be set according to requirements and is not limited herein.

[0059] In some embodiments, please refer to Figure 3-6A rotating shaft is provided at the connection between the blade 6 and the fixed bracket 1, allowing the blade 6 to move away from the fixed bracket 1 along the rotating shaft; the rotation directions of the multiple blades 6 in a single intake unit 10 are different. Compared to single-opening or double-opening (i.e., opening in two directions), this application saves more internal space. Furthermore, in externally mounted air intake grilles, regulations prohibit outward opening; a single-opening shaft in the middle does not meet regulatory requirements, and an inward-opening shaft on the side wastes internal space. This application's multi-directional inward opening saves internal space while meeting air intake requirements. Moreover, a single-opening air intake direction deviates from the driving direction, which can affect vehicle stability at higher speeds. This application, along with the symmetrical opening of the double-opening blades, ensures that the air intake and driving directions are aligned, thus not affecting vehicle stability. It should be noted that the rotating shaft can be a full shaft or a half shaft; preferably, a full shaft improves the safety performance of the air intake grille during operation.

[0060] In some embodiments, the active air intake grille has an arc-shaped surface. The active air intake grille of this application has an arc-shaped surface, enabling its movement within the arc-shaped surface. After the active air intake grille is installed on the vehicle, the arc-shaped structure provides a large usable space, which can accommodate bumpers of various structures, thus having a wide range of applications. Furthermore, the active air intake grille of this application has a more aesthetically pleasing appearance.

[0061] In some embodiments, please refer to Figure 15 , Figure 15 This is a schematic diagram of the air intake grille of the air intake unit 10 with different shapes according to embodiments of this application. The shape of the blade 6 includes at least one of triangle, trapezoid, and fan shape. The trapezoid can include a straight trapezoid and a trapezoid with an arc bottom; the shape of the air intake unit 10 includes at least one of circle and polygon. Specifically, the blades are arranged in a ring. For example, when the blades are triangular and one air intake unit 10 has 3 blades, the shape formed by the 3 blades closing is a triangle, that is, one air intake unit 10 is triangular. Please refer to [reference needed] for details. Figure 15 (c) When the blades are triangular and one intake unit 10 has 4 blades, the shape formed when the 4 blades are closed is a square. That is, one intake unit 10 is a quadrilateral. Please refer to [reference needed] for details. Figure 15 (d) When the blades are triangular and one intake unit 10 has 5 blades, the shape formed by the 5 blades when closed is a pentagon. That is to say, one intake unit 10 is a pentagon. Please refer to [reference needed] for details. Figure 15 (a) When the blades are triangular and one intake unit 10 has 6 blades, the shape formed by the 6 blades when closed is hexagonal, meaning one intake unit 10 is hexagonal; when the blades are fan-shaped and one intake unit 10 has 4 blades, the shape formed by the 4 blades when closed is circular, meaning one intake unit 10 is circular. Please refer to [reference needed] for details. Figure 15(b) It should be noted that the shape and structure of the linkage support can be adapted to changes in the shape and structure of the blade.

[0062] In some embodiments, the fixed bracket is provided with an air intake unit mounting port, and the air intake unit mounting port is provided one-to-one with the air intake unit 10; the shape of the air intake unit mounting port includes at least one of circular and polygonal shapes, and multiple blades are arranged circumferentially along the edge of the air intake unit mounting port. A support frame 23 is provided inside the air intake unit mounting port. For example, when the air intake unit 10 is hexagonal, the support frame 23 divides the hexagonal air intake port into 6 triangular windows, and each triangular window is provided with a triangular blade.

[0063] In some embodiments, the fixed bracket is further provided with a redundant blade mounting port 22, which is located between adjacent intake unit mounting ports. Corresponding blades are installed within the redundant blade mounting port 22. During the rotation of the intake unit blades driven by the linkage bracket, the blades within the redundant blade mounting port 22 are simultaneously rotated. Where space permits, redundant blade mounting ports 22 and their corresponding blades of different shapes and structures can be provided as needed. For examples, please refer to [reference needed]. Figure 1 and Figure 7 , Figure 1 and Figure 7 A triangular redundant blade mounting port 22 is provided at the upper and lower ends of the two adjacent hexagonal air intake unit mounting ports.

[0064] In some embodiments, the rotation angle of the blade 6 is 0-85°. It should be noted that the rotation angle of the air intake grille blades can be controlled according to the heat dissipation requirements of the entire vehicle. The maximum rotation angle of the air intake grille in this application can reach 85°. Moreover, based on the multi-blade arrangement, under the same blade opening angle, compared with the traditional active air intake grille, the active air intake grille of this application has a larger effective air intake area, which improves the heat dissipation efficiency.

[0065] In a preferred embodiment, the maximum rotation angle of the blade 6 approaches a right angle.

[0066] In some embodiments, the first linkage mechanism 4 can be a screw, and the linkage bracket is provided with a screw hole that matches the screw. The drive device is connected to the screw, and the drive device directly drives the screw to rotate. The screw is generally perpendicular to the outer surface of the active air intake grille, and when the screw moves, it drives the linkage bracket to move generally along the outer surface of the grille.

[0067] In some embodiments, please refer to Figure 10-11 The first linkage mechanism 4 can be a two-bar linkage, a Y-shaped eight-bar linkage, or other structures. The first linkage mechanism 4 is used to drive the linkage support to move, and the specific structure is not limited to the above example.

[0068] In some embodiments, please refer to Figure 12-14 The second linkage mechanism 5 includes at least one of a lotus leaf motion mechanism, a scissor-shaped motion fork arm, and a Y-shaped eight-bar linkage mechanism. The second linkage mechanism 5 is used to transmit the force of the first linkage mechanism located at the bottom of the linkage support to the upper end of the linkage support, thereby ensuring that the entire linkage support is subjected to uniform force and maintains motion balance. The specific structure of the second linkage mechanism 5 is not limited to the above example.

[0069] In some embodiments, the drive device is further provided with a reduction gear. During the process of the drive device driving the first linkage mechanism, the reduction gear can be used to increase the torque, and the gear ratio can be 1:2.6.

[0070] In some embodiments, the external active air intake grille is manufactured by injection molding.

[0071] The active air intake grille closing process of this application is as follows: Under the drive of the drive device, the first linkage mechanism moves in the direction close to the fixed bracket, thereby pulling the linkage bracket to move in a straight line in the direction close to the fixed bracket. The linkage bracket pushes the blade linkage mechanism to rotate, so that the blades rotate along the rotation axis until all the blades are closed, thereby realizing the closing of the active air intake grille.

[0072] The active air intake grille opening process of this application is as follows: Under the drive of the drive device, the first linkage mechanism moves away from the fixed bracket, thereby pulling the linkage bracket to move linearly away from the fixed bracket. The linkage bracket pulls the blade linkage mechanism to rotate, causing the blades to rotate along the rotation axis. When the blades are at the desired rotation angle, the active air intake grille opens. It should be noted that, according to different needs, the first linkage mechanism can be controlled to move to different positions by the drive motor, thereby opening the blades to different angles and controlling the effective air intake area of ​​the active air intake grille.

[0073] This application also provides a vehicle including the active grille shutter as described above.

[0074] By adopting the above technical solution, the active air intake grille and vehicle provided in this application have the following beneficial effects:

[0075] This application, by setting multiple blades, significantly increases the effective air intake area compared to traditional active air intake grilles under the same blade opening angle, thus improving heat dissipation efficiency. Furthermore, by setting multiple blades, the wind force is distributed among multiple blades within the same blade area, improving the overall air intake unit's load-bearing capacity and reducing its susceptibility to damage. Finally, by connecting multiple sets of blades to a linkage bracket, the air intake unit opens and closes as the linkage bracket moves along its thickness direction, ensuring the synchronicity of each blade's movement.

[0076] This application sets up a first linkage mechanism and a second linkage mechanism to transmit the force on the first linkage mechanism to the second linkage mechanism. The first linkage mechanism and the second linkage mechanism work together to drive the linkage support to move, ensuring the balance, synchronization and simultaneity of the linkage support during movement, thereby improving the angular synchronization and angular stability when multiple blades rotate.

[0077] This application achieves diverse airflow angles by setting multiple blades and having multiple blades in a single air intake unit rotate in different directions, thereby delivering the intake air to various locations in the vehicle that require heat dissipation.

[0078] The active air intake grille of this application has an arc-shaped exterior structure, which provides a large usable space in the vehicle. This space can accommodate bumpers of various structures, making it widely applicable. In addition, the active air intake grille of this application has a more aesthetically pleasing appearance.

[0079] The foregoing description has fully disclosed the specific embodiments of this application. It should be noted that any modifications made by those skilled in the art to the specific embodiments of this application do not depart from the scope of the claims. Accordingly, the scope of the claims of this application is not limited to the foregoing specific embodiments.
