Description

Air intake grille, front bumper assembly and vehicle Technical Field

[0001] The present application relates to the field of mechanical and electronic technology, and in particular to an air intake grille, a front bumper assembly and a vehicle. Background Art

[0002] The air intake grille is located at the front of the vehicle, allowing cool air to enter the front cabin. It has a certain impact on the vehicle's heat dissipation, wind resistance, energy consumption, and NVH (noise, vibration, harshness) performance.

[0003] An AGS (active grille shutter) is a grille that actively controls air intake by changing its opening and closing state. This control can be used to control heat dissipation, wind resistance, and other factors. Currently, grilles primarily open and close using blades similar to Venetian blinds. When the blades rotate perpendicular to the airflow direction, the grille closes. When the blades rotate parallel to the airflow direction, the grille opens.

[0004] At present, the air intake grille with this structure requires the blades to have a larger movement space, resulting in the air intake grille occupying a larger space at the front of the vehicle.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide an air intake grille, a front bumper assembly, and a vehicle, which can overcome the problems in the related art. The technical solutions are as follows:

[0007] In a first aspect, embodiments of the present application provide an air intake grille comprising a baffle and a movable plate. The baffle defines an air inlet. The movable plate is disposed opposite and connected to the baffle. The movable plate is movable relative to the baffle in a plane parallel to the baffle, thereby varying the area of ​​the air inlet blocked by the movable plate.

[0008] Based on the above features, when adjusting the movable plate, the movable plate moves in a plane parallel to the baffle, so the movable plate does not need to occupy a large movement space, thereby making the structure of the air intake grille more compact and occupying smaller space in the front part of the vehicle.

[0009] In some examples, the movable plate is slidably connected to the baffle, that is, the movable plate translates relative to the baffle to change the air intake volume.

[0010] In other examples, the movable plate is rotatably connected to the baffle. That is, the movable plate rotates relative to the baffle to change the amount of air intake. Furthermore, the movable plate's rotational movement relative to the baffle requires less space and can make the air intake grille more compact.

[0011] Optionally, the movable plate is circular, and the center of the movable plate is located on the rotation axis of the movable plate.

[0012] Based on the above features, during the rotation of the movable plate, the circular movable plate requires less space than other shapes and will not occupy the layout space of other adjacent structures.

[0013] Optionally, the air intake grille includes multiple movable panels, the air intake includes multiple groups of through holes, and the multiple movable panels are arranged in a one-to-one correspondence with the multiple groups of through holes. Providing multiple movable panels and multiple groups of through holes can make the overall shape of the air intake grille more complex and varied, adapting to different vehicles.

[0014] In some examples, the plurality of movable panels are arranged in a row. In other examples, the plurality of movable panels are arranged in multiple rows. The arrangement of the plurality of movable panels can be configured based on the specific requirements of the vehicle's styling and performance.

[0015] Optionally, the plurality of movable panels are linked to each other so that the plurality of movable panels can move together, thereby changing the shielding area of ​​the air inlet and adjusting the air intake volume.

[0016] As an example, the edges of the multiple movable plates are each provided with transmission teeth, and the transmission teeth of the multiple movable plates are meshed with each other.

[0017] Based on the above features, transmission teeth are provided on the edge of the movable plate, making the structure of the movable plate equivalent to a gear. Multiple movable plates cooperate with each other to form a gear mechanism, so that when any movable plate rotates, the other movable plates will also rotate together, thereby achieving linkage.

[0018] In other examples, the movable plates may also be configured as friction wheels, and the edges of the multiple movable plates may fit together to transmit power through friction, thereby achieving linkage.

[0019] Optionally, the transmission mechanism is in driving connection with the plurality of movable panels. In addition to achieving linkage of the plurality of movable panels through direct contact between the plurality of movable panels, the provision of the transmission mechanism to transmit power and achieve linkage can make the arrangement of the plurality of movable panels more flexible, and the overall shape of the air intake grille more diverse, meeting the design requirements of different vehicle models.

[0020] As an example, the transmission mechanism includes a rack, and the edges of the multiple movable plates are each provided with transmission teeth, and the transmission teeth of the multiple movable plates are engaged with the rack.

[0021] Based on the above features, the multiple movable plates are equivalent to multiple gears, and the multiple movable plates respectively cooperate with the rack to form a gear-rack mechanism. When any of the movable plates rotates, it can drive the other movable plates to rotate together through the rack; when the rack moves, it can also drive all the movable plates to rotate together, thereby realizing the linkage of the multiple movable plates.

[0022] Optionally, the rack is a single-sided rack or a double-sided rack. When the rack is a double-sided rack, the multiple movable plates are located on the same side of the double-sided rack, or some of the multiple movable plates are located on one side of the double-sided rack, and another part of the multiple movable plates are located on the other side of the double-sided rack.

[0023] As another example, the transmission mechanism includes a worm, and edges of the multiple movable plates each have transmission teeth, and the transmission teeth of the multiple movable plates are engaged with the worm.

[0024] Based on the above features, the movable plates and the worm form a worm gear mechanism. By providing the worm to drive the multiple movable plates, the rotation of the worm can be converted into rotation of the movable plates. The worm drives the movable plates by rotating itself, without generating translational motion, occupies less space, and can make the air intake grille structure more compact.

[0025] As another example, the transmission mechanism includes a transmission belt, and the transmission belt is wound around edges of the multiple movable plates, so that the multiple movable plates are driven to move in a linked manner through the transmission belt.

[0026] The transmission belt structure is flexible and can be bent into complex shapes when arranged. The distribution requirements for the multiple movable plates are relatively low. Even if the multiple movable plates are distributed relatively dispersedly, they can still be linked through the transmission belt.

[0027] Exemplarily, the transmission belt includes a belt and a chain. The belt and the plurality of movable plates form a belt mechanism; the chain and the plurality of movable plates form a chain mechanism. The belt may further include a flat belt, a V-belt, or a meshing belt, and the cross-sectional shape of the belt may be configured according to the structure of the movable plates.

[0028] Optionally, the air intake grille further includes a drive mechanism. The drive mechanism is configured to drive the movable panels. The drive mechanism is configured based on the specific structure of the air intake grille. The drive mechanism can be mounted on the baffle or fixed to the vehicle body. The drive mechanism can be configured based on the linkage arrangement of the multiple movable panels. Exemplarily, the drive mechanism includes an electric motor, which is configured to provide power for the movement of the multiple movable panels.

[0029] Optionally, the baffle includes a mounting plate and a fixed plate corresponding to the movable plate, the mounting plate having a mounting hole, the fixed plate being embedded in the mounting hole and detachably connected to the mounting plate. The air inlet is located on the fixed plate.

[0030] Based on the above features, different air intakes can be set by replacing the fixing plate, and the shape of the air intake grille can also be changed to make the vehicle's shape richer.

[0031] In some examples, the edge of the fixing plate has a slot, and the inner wall of the mounting hole has a protrusion, which is engaged with the slot. Through the cooperation between the slot and the protrusion, the fixing plate can be more stably and firmly installed in the mounting hole.

[0032] In a second aspect, an embodiment of the present application provides a front bumper assembly, which includes a bumper skin and an air intake grille as described in the first aspect, wherein the air intake grille is connected to the bumper skin.

[0033] Based on the above features, in the front bumper assembly, by arranging the movable plate of the air intake grille relative to the baffle, when adjusting the movable plate, the movable plate moves in a plane parallel to the baffle, so the movable plate does not need to occupy a large movement space, thereby making the structure of the air intake grille more compact and occupying smaller space in the front part of the vehicle.

[0034] In some examples, the baffle of the air intake grille is an integral structure with the bumper cover, that is, the air intake is directly arranged on the bumper cover, which can make the structure of the front bumper assembly more compact.

[0035] In a third aspect, an embodiment of the present application provides a vehicle, comprising the air intake grille as described in the first aspect, or the front bumper assembly as described in the second aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The terms used in the embodiments of this application are intended solely to illustrate the embodiments of this application and are not intended to limit this application. Unless otherwise defined, technical or scientific terms used in the embodiments of this application should have the same ordinary meaning as those understood by persons of ordinary skill in the art to which this application belongs.

Terms such as "include" or "comprising" and similar terms mean that the elements or objects listed before "include" or "comprising" include the elements or objects listed after "include" or "comprising," and their equivalents, and do not exclude other elements or objects. Terms such as "connected" or "connected" are not limited to physical or mechanical connections but may include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used solely to indicate relative positions. When the absolute position of the described objects changes, the relative positions may also change accordingly.

[0056] Figure 1 is a schematic diagram of the structure of an air intake grille provided in an embodiment of the present application. As shown in Figure 1, the air intake grille includes a baffle 10 and a movable plate 20. The baffle 10 has an air inlet 10a.

[0057] The movable plate 20 is arranged opposite to and connected to the baffle 10. The movable plate 20 is configured to be movable relative to the baffle 10 in a plane parallel to the baffle 10, thereby changing the shielding area of ​​the movable plate 20 on the air inlet 10a.

[0058] The air inlet 10a is used for air intake, and the movable plate 20 is used for shielding the air inlet 10a. By changing the shielding area of ​​the air inlet 10a by the movable plate 20, the air intake amount can be changed.

[0059] The blocked area refers to the area where the projection of the movable panel 20 on the baffle 10 overlaps with the air inlet 10a. The blocked area can range from 0 to a maximum value, where the maximum value is the area of ​​the air inlet 10a. In other words, the movement of the movable panel 20 can leave the air inlet 10a unobstructed, partially obstructed, or completely obstructed.

[0060] The amount of air intake through the air intake grille is related to many factors, such as vehicle speed, ambient wind speed, wind direction, and the open area of ​​the air intake 10a. The open area of ​​the air intake 10a is the difference between the area of ​​the air intake 10a and the blocked area. When the ambient wind speed and wind direction remain unchanged and the open area of ​​the air intake 10a remains unchanged, the faster the vehicle speed, the higher the air intake. When the vehicle speed, ambient wind speed, and wind direction remain unchanged, the larger the open area of ​​the air intake 10a, the greater the air intake. When multiple factors change at the same time, it is naturally difficult to determine whether the air intake will ultimately increase or decrease. In this application, unless otherwise specified, the effect of the open area of ​​the air intake 10a on the air intake is discussed under the assumption that other factors such as vehicle speed, ambient wind speed, and wind direction remain unchanged. For example, changing the air intake means that other factors such as vehicle speed, ambient wind speed, and wind direction remain unchanged, and the air intake is changed by changing the open area of ​​the air intake 10a.

[0061] By arranging the movable panel 20 relative to the baffle 10, and when adjusting the movable panel 20, the movable panel 20 moves in a plane parallel to the baffle 10, so that the movable panel 20 does not need to occupy a large movement space, the structure of the air intake grille can be more compact and the space occupied at the front of the vehicle is smaller.

[0062] The air intake grille may further include a drive mechanism for driving the movable plate 20. The structure of the drive mechanism may be configured according to the specific structure of the air intake grille, as described below. The drive mechanism may be mounted on the baffle 10 or fixed to the vehicle body.

[0063] For example, the driving mechanism may include an electric motor as a power source to provide power for moving the movable panel 20 .

[0064] In some examples, the movable panel 20 is slidably connected to the baffle 10 , such that the movable panel 20 can slide relative to the baffle 10 .

[0065] For example, Figure 2 is a structural schematic diagram of an air intake grille provided in an embodiment of the present application. As shown in Figure 2, the movable panel 20 can be moved along the height direction of the vehicle, that is, in the manner shown by the arrow in Figure 2, by changing the relative position of the movable panel 20 and the air intake 10a, the blocking area of ​​the movable panel 20 on the air intake 10a can be changed.

[0066] In other examples, the movable panel 20 may also move in other directions. The movable panel 20 may move in any direction as long as it can block the air inlet 10a.

[0067] Optionally, a guide structure may be provided between the baffle 10 and the movable plate 20 to limit the movement direction of the movable plate 20 so that the movable plate 20 can move more smoothly.

[0068] For example, Figure 3 is a schematic diagram of the installation of a movable panel provided in an embodiment of the present application. Figure 3 corresponds to the top view of Figure 2. As shown in Figure 3, a guide slot 10b may be provided on the side of the baffle 10 adjacent to the movable panel 20, and the movable panel 20 is installed in the guide slot 10b.

[0069] The air inlet 10a may include multiple groups of through holes 12a, each group including at least one through hole 12a. In some examples, the movable panels 20 may be disposed corresponding to the multiple groups of through holes 12a, and the multiple groups of through holes 12a may be shielded by one movable panel 20.

[0070] As an example, the air intake grille can include multiple movable panels 20, each corresponding to a plurality of through-holes 12a. Each movable panel 20 is slidably connected to the baffle 10, allowing each movable panel 20 to be independently adjusted. The multiple movable panels 20 can also be connected, as shown in FIG2 , to enable linkage.

[0071] There can be a variety of settings for the shape of the through holes 12a, for example, it can be circular, elliptical, polygonal, etc. There can also be a variety of settings for multiple groups of through holes 12a. Figures 4 to 7 are schematic diagrams of the distribution of multiple groups of through holes provided in the embodiments of the present application. For example, as shown in Figure 4, multiple groups of through holes 12a can be distributed in a row; for example, as shown in Figures 5, 6 or 7, multiple groups of through holes 12a can be distributed in multiple rows, each row can include at least one group of through holes 12a, and the number of groups of through holes 12a in each row can be the same or different. Multiple movable panels 20 are arranged in one or more rows. The distribution of the air intake 10a can be set according to the specific vehicle to meet the vehicle's requirements for heat dissipation, wind resistance, energy consumption, NVH performance, etc., as well as the vehicle's appearance design requirements.

[0072] Figure 8 is a schematic diagram of the structure of an air intake grille provided in an embodiment of the present application. As shown in Figure 8 , the drive mechanism of the air intake grille may include a motor 31, a first drive wheel 32, and a second drive wheel 33. The motor 31 is located to the side of the movable panel 20, and the first drive wheel 32 is coaxially connected to the rotating shaft of the motor 31. The second drive wheel 33 is located between the first drive wheel 32 and a side edge of the movable panel 20. The second drive wheel 33 cooperates with the first drive wheel 32 and the movable panel 20. The motor 31 drives the first drive wheel 32 to rotate, which in turn drives the second drive wheel 33 to rotate, and finally the second drive wheel 33 drives the movable panel 20 to move.

[0073] For example, one side of the movable plate 20 may be parallel to the direction of movement of the movable plate 20, the first drive wheel 32 and the second drive wheel are friction wheels, and the second drive wheel 33 contacts the side of the movable plate 20. When the second drive wheel 33 rotates, the movable plate 20 is driven to move by friction.

[0074] Optionally, the first drive wheel 32 and the second drive wheel 33 can also be gears, and teeth can be distributed on the side of the movable plate 20. The teeth of the second drive wheel 33 engage with the teeth on the edge of the movable plate 20. When the second drive wheel 33 rotates, it drives the movable plate 20 to move.

[0075] The radii of the first drive wheel 32 and the second drive wheel 33 can be different. For example, the radius of the second drive wheel 33 is larger than the radius of the first drive wheel 32, so that the first drive wheel 32 and the second drive wheel 33 cooperate to function as a speed reducer. In other examples, the second drive wheel 33 can be omitted, and the first drive wheel 32 can directly cooperate with the movable plate 20.

[0076] For the air intake grille shown in FIG8 , the drive mechanism can take a variety of forms, as long as it can drive the movable plate 20 to move horizontally, thereby changing the area of ​​the movable plate 20 blocking the air intake 10a. For example, the drive mechanism can be a linear motor, with the fixed portion of the linear motor connected to the baffle 10 and the moving portion connected to the movable plate 20.

[0077] In other examples, the movable plate 20 may also be rotatably connected to the baffle 10, so that the movable plate 20 can rotate relative to the baffle 10. The movable plate 20 moves relative to the baffle 10 in a rotating manner, which requires less space and can make the structure of the air intake grille more compact.

[0078] Exemplarily, the movable plate 20 is connected to the baffle 10 via a pin, and the movable plate 20 can rotate around the pin.

[0079] 1 , the movable plate 20 is circular, and the center of the circle is located on the rotation axis of the movable plate 20 .

[0080] The movable plate 20 is set to be circular. During the rotation of the movable plate 20 , the circular movable plate 20 requires less space than other shapes and will not occupy the arrangement space of other adjacent structures.

[0081] The movable plate 20 may be provided with ventilation holes 20a. By rotating the movable plate 20 and changing the overlapping area between the ventilation holes 20a and the air inlet 10a, the air intake volume can be changed.

[0082] The vent hole 20a is eccentrically arranged. As the movable plate 20 rotates, the larger the overlapping area of ​​the vent hole 20a and the air inlet 10a, the greater the air intake, and the smaller the overlapping area of ​​the vent hole 20a and the air inlet 10a, the smaller the air intake.

[0083] The movable plate 20 may be provided with a plurality of vent holes 20a, which are arranged along the circumference of the movable plate 20, for example, at equal angles. For example, the interval angles may be 60°, 90°, 120°, or 180°.

[0084] As shown in FIG1 , the air inlet 10a may include multiple groups of through holes 12a. Each group includes multiple through holes 12a. The air intake grille includes multiple movable panels 20, which are arranged in a one-to-one correspondence with the multiple groups of through holes 12a. The shape and distribution of the air vents 20a on the movable panels 20 may be identical to the shape and distribution of the corresponding multiple through holes 12a, so that by rotating the movable panels 20, the multiple air vents 20a on the same movable panel 20 can be aligned one-to-one with the same group of through holes 12a.

[0085] The shape of the vent 20a can be the same as the shape of the through hole 12a on the baffle 10. For example, as shown in Figure 1, the vent 20a can be fan-shaped. For another example, Figures 9 to 11 are schematic diagrams of the structure of the movable plate 20 provided in an embodiment of the present application. As shown in Figure 9, the vent 20a can be triangular, or even equilateral. For another example, as shown in Figure 10, the vent 20a can be rectangular. For another example, as shown in Figure 11, the vent 20a can be circular.

[0086] Not only can the multiple movable panels 20 in the air intake grille where the movable panel 20 moves horizontally relative to the baffle 10 be linked together, but the multiple movable panels 20 in the air intake grille where the movable panel 20 is rotatably connected to the baffle 10 can also be linked together.

[0087] For example, multiple movable plates 20 can be directly coupled to each other, enabling the multiple movable plates 20 to be linked. Figure 12 is a schematic diagram of the coupling between a movable plate and a drive mechanism provided in an embodiment of the present application. As an example, as shown in Figure 12, the edges of the multiple movable plates 20 each have transmission teeth 201, and the transmission teeth 201 of the multiple movable plates 20 mesh with each other.

[0088] By providing transmission teeth 201 on the edge of the movable plate 20, the structure of the movable plate 20 is equivalent to a gear. Multiple movable plates 20 cooperate with each other to form a gear mechanism, so that when any movable plate 20 rotates, the other movable plates 20 will also rotate together.

[0089] The diameters of the multiple movable plates 20 can be the same or different. When the diameters of the multiple movable plates 20 are the same, the transmission ratio between two meshing movable plates 20 is 1:1, which ensures that the rotation speeds of the multiple movable plates 20 are the same when adjusting the intake air volume. When the diameters of the multiple movable plates 20 are different, the transmission ratio between two meshing movable plates 20 is not 1:1, which allows the rotation speeds of the multiple movable plates 20 to be different when adjusting the intake air volume.

[0090] As shown in Figure 12, the drive mechanism of the air intake grille includes a motor 31, a first drive wheel 32, and a second drive wheel 33. The motor 31 can be positioned to the side of a movable panel 20 and connected to the baffle 10. The first and second drive wheels 32, 33 are gears that mesh with each other. The second drive wheel 33 meshes with a movable panel 20, thereby driving the rotation of multiple movable panels 20.

[0091] In other examples, the second drive wheel 33 may be omitted, and the first drive wheel 32 may be directly matched with the movable plate 20; or even the first drive wheel 32 may be omitted, and the rotating shaft of the motor 31 may be directly coaxially connected to a movable plate 20, thereby driving multiple movable plates 20 to rotate.

[0092] In the example shown in Figure 12, the movable plate 20 is a gear structure, and the multiple movable plates 20 form a linkage through cooperation with each other. In other examples, the movable plate 20 can also be a friction wheel structure, that is, the multiple movable plates 20 drive each other through friction to achieve linkage.

[0093] In addition to achieving linkage of the multiple movable panels 20 through direct action between the multiple movable panels 20, a transmission mechanism may also be provided, which is in transmission connection with the multiple movable panels 20, and the transmission mechanism is used to achieve linkage of the multiple movable panels 20. That is, the air intake grille may also include a transmission mechanism, which is in transmission connection with the multiple movable panels 20.

[0094] The transmission mechanism can take a variety of forms, as long as it can achieve interlocking motion between the multiple movable panels 20. As an example, Figure 13 illustrates the coordination of a movable panel, transmission mechanism, and drive mechanism, as provided in an embodiment of the present application. As shown in Figure 13 , the transmission mechanism of the air intake grille includes a rack 41. Each of the multiple movable panels 20 has transmission teeth 201 along its edge, which mesh with the rack 41.

[0095] In this air intake grille, the multiple movable panels 20 are equivalent to multiple gears. The multiple movable panels 20 are separated from each other and each cooperates with the rack 41 to form a rack-and-pinion mechanism. When any one of the multiple movable panels 20 rotates, it can drive the other movable panels 20 to rotate together through the rack 41; when the rack 41 moves, it can also drive all the movable panels 20 to rotate together.

[0096] The rack 41 can be a single-sided rack, that is, the rack 41 has teeth distributed on only one side, or a double-sided rack, that is, the rack 41 has teeth distributed on both sides.

[0097] Multiple movable plates 20 can be distributed on the same side of the rack 41 so as to rotate together under the drive of the rack 41. When the rack 41 is a double-sided rack, some movable plates 20 can be located on one side of the rack 41 and other movable plates 20 can be located on the other side of the rack 41. For example, two movable plates 20 are arranged on each side of the rack 41.

[0098] As shown in Figure 13, the drive mechanism of the air intake grille includes a motor 31, a first drive wheel 32, and a second drive wheel 33. The motor 31 can be arranged on one side of the rack 41. The motor 31 can be connected to the baffle 10. The first drive wheel 32 and the second drive wheel 33 are gears that mesh with each other. The first drive wheel 32 is coaxially connected to the rotating shaft of the motor 31. The second drive wheel 33 meshes with the rack 41, driving the rack 41 to move linearly, thereby driving the multiple movable panels 20 to rotate through the rack 41. The second drive wheel 33 can also mesh with a single movable panel 20, and can also drive multiple movable panels 20 to rotate.

[0099] In other examples, the second drive wheel 33 can be omitted, and the first drive wheel 32 can be directly engaged with the rack 41 or a movable plate 20. The first drive wheel 32 can even be omitted, and the rotating shaft of the motor 31 can be coaxially connected to a movable plate 20, thereby driving multiple movable plates 20 to rotate.

[0100] Optionally, the drive mechanism may also include a linear motor connected to the rack 41 to drive the rack 41 to move linearly, thereby driving the multiple movable plates 20 to rotate. Directly driving the rack 41 to move by the linear motor makes the structure simpler. In addition, the linear motor has a fast response speed and can quickly change the air intake volume of the air intake grille. The linear motor has high motion accuracy at both high and low speeds, which is conducive to accurately adjusting the air intake volume of the air intake grille. After the linear motor is locked, the rack 41 is directly locked, and the range of motion of the movable plate 20 caused by the fitting clearance is also smaller, making the movable plate 20 more stable.

[0101] As another example, Figure 14 illustrates the coordination of a movable panel, a transmission mechanism, and a drive mechanism according to an embodiment of the present application. As shown in Figure 14 , the transmission mechanism of the air intake grille includes a worm 42. The edges of the movable panels 20 each have transmission teeth 201 that mesh with the worm 42.

[0102] The movable panels 20 and the worm 42 form a worm gear mechanism. By providing the worm 42 to drive multiple movable panels 20, the rotation of the worm 42 can be converted into rotation of the movable panels 20. When the rack 41 drives the movable panels 20, the rack 41 performs a translational motion, while the worm 42 drives the movable panels 20 by rotating, without generating translational motion. This occupies less space and allows for a more compact air intake grille structure.

[0103] As shown in Figure 14, the driving mechanism includes a motor 31, which is located at one end of a worm 42, and a rotating shaft of the motor 31 is connected to the worm 42. The motor 31 drives the worm 42 to rotate, thereby driving the movable plate 20 to rotate.

[0104] Alternatively, a first drive wheel may be provided on the rotating shaft of the motor 31, and a second drive wheel may be connected to the worm 42, with the first and second drive wheels cooperating with each other. For example, both the first and second drive wheels may be gears, and the first and second drive wheels may mesh with each other. Thus, the first and second drive wheels 32, 33 cooperate to function as a speed reducer.

[0105] As another example, the transmission mechanism may include a transmission belt, which is wound around the edges of the plurality of movable panels 20. The transmission belt may be a belt, a chain, or other structure that can implement belt transmission.

[0106] FIG15 is a schematic diagram of the coordination of a movable panel, a transmission mechanism, and a drive mechanism provided in an embodiment of the present application. As shown in FIG15 , in the air intake grille, the transmission mechanism includes a belt 43. The belt 43 is wound around the edges of the plurality of movable panels 20.

[0107] The belt 43 and the edges of the movable plates 20 have friction. When the belt 43 rotates, the friction drives the multiple movable plates 20 to rotate synchronously.

[0108] The belt 43 may be a meshing belt, i.e., the inner surface of the belt 43 may be provided with teeth. Accordingly, the edge of the movable plate 20 may also be provided with teeth, and the teeth of the belt 43 mesh with the teeth of the movable plate 20. Compared to a conventional flat belt, a meshing belt can improve transmission stability and prevent slippage between the belt 43 and the movable plate 20.

[0109] As shown in Figure 15 , the drive mechanism of the air intake grille includes a motor 31, a first drive wheel 32, and a second drive wheel 33. The motor 31 can be positioned inside or outside the belt 43. The motor 31 can be connected to the baffle 10. The first drive wheel 32 and the second drive wheel 33 are friction wheels that contact each other. Of course, if the belt 43 is a meshing belt, the first drive wheel 32 and the second drive wheel 33 can also be gears.

[0110] The first drive wheel 32 is coaxially connected to the rotating shaft of the motor 31. The second drive wheel 33 is in contact with the belt 43, which drives the belt 43 to rotate, thereby driving the multiple movable panels 20 to rotate via the belt 43. The second drive wheel 33 can also contact the edge of a movable panel 20, driving the movable panel 20 to rotate via the second drive wheel 33, and then the movable panel 20 drives the other movable panels 20 to rotate via the belt 43.

[0111] In order to improve the stability of the transmission, as shown in Figure 16, one of the first drive wheel 32 and the second drive wheel 33 can be located on the inner side of the belt 43, and the other can be located on the outer side of the belt 43. The belt 43 is sandwiched between the first drive wheel 32 and the second drive wheel 33.

[0112] In other examples, the second drive wheel 33 can be omitted, and the first drive wheel 32 can directly contact the belt 43 or the movable plate 20 to drive the belt 43 to rotate through friction. The first drive wheel 32 can even be omitted, and the rotating shaft of the motor 31 can be directly connected coaxially with a movable plate 20 to drive the belt 43 to rotate through the movable plate 20.

[0113] As shown in FIG. 15 or FIG. 16 , the driving mechanism may further include at least one auxiliary wheel 44 . The auxiliary wheel 44 contacts the belt 43 and is used to tighten the belt 43 to prevent the belt 43 from becoming loose and affecting the rotation of the movable plate 20 .

[0114] As an example, in Figure 15, three movable panels 20 are arranged in a triangular pattern, and the line connecting the centers of the three movable panels 20 forms a triangle, such as an equilateral triangle. In other examples, the multiple movable panels 20 can also be arranged in other ways, such as arranging the centers of the three movable panels 20 on a collinear basis.

[0115] Figure 17 is a schematic diagram illustrating the coordination of a movable panel, transmission mechanism, and drive mechanism according to an embodiment of the present application. As shown in Figure 17 , the transmission mechanism in the air intake grille includes a chain 45, which is wound around the edges of multiple movable panels 20. The edges of the movable panels 20 are provided with sprockets that engage with the chain 45.

[0116] During the rotation of the chain 45, the movable plate 20 is rotated by the sprockets. The use of the chain 45 to drive the rotation of multiple movable plates 20 can also improve the stability of the transmission and avoid slipping between the chain 45 and the movable plate 20.

[0117] As shown in Figure 17, the drive mechanism of the air intake grille can include a motor 31 and a first drive wheel 32. The motor 31 can be positioned inside or outside the chain 45. The motor 31 can be connected to the baffle 10. The first drive wheel 32 is a sprocket. The first drive wheel 32 is connected to the rotating shaft of the motor 31 and cooperates with the chain 45. The first drive wheel 32 drives the chain 45 to rotate, thereby driving the multiple movable panels 20 to rotate.

[0118] In other examples, the first driving wheel 32 may also be omitted, and the rotating shaft of the motor 31 may be directly coaxially connected to a movable plate 20 , and the chain 45 may be driven to rotate via the movable plate 20 .

[0119] As shown in FIG17 , the drive mechanism may further include at least one auxiliary wheel 44 , which is also a sprocket. The auxiliary wheel 44 cooperates with the chain 45 to tension the chain 45 and prevent the chain 45 from becoming loose and affecting the rotation of the movable plate 20 .

[0120] Figure 18 is a schematic diagram of the structure of a baffle provided in an embodiment of the present application. As shown in Figure 18 , the baffle 10 comprises a mounting plate 11 and a fixed plate 12, which is arranged in a one-to-one correspondence with the movable plate 20. The mounting plate 11 has a mounting hole 11a, and the fixed plate 12 is inserted into the mounting hole 11a and is removably connected to the mounting plate 11. The air inlet 10a is located on the fixed plate 12.

[0121] By configuring the baffle 10 to be composed of a mounting plate 11 and a fixing plate 12 , different air inlets 10 a can be provided by replacing the fixing plate 12 , and the shape of the vehicle can also be changed.

[0122] For example, as shown in FIG18 , the edge of the fixing plate 12 may have a slot 121, and the inner wall of the mounting hole 11a may have a protrusion 111, which engages with the slot 121. The engagement between the slot 121 and the protrusion 111 allows a better seal to be formed between the edge of the fixing plate 12 and the edge of the mounting hole 11a, thereby reducing air leakage, improving the stability of the fixing plate 12 installation, and preventing the fixing plate 12 from loosening.

[0123] The thickness of the fixed plate 12 can be consistent with the thickness of the movable plate 20. For example, the sum of the thickness of the fixed plate 12 and the thickness of the movable plate 20 can be 10 mm to 15 mm. For another example, the thickness of the fixed plate 12 is 6 mm to 8 mm, and the thickness of the movable plate 20 is 6 mm to 8 mm. In this example, the thickness of the fixed plate 12 is 8 mm, and the thickness of the movable plate 20 is also 8 mm.

[0124] As an example, the edge of the fixing plate 12 may also be provided with a sealing ring that engages in the retaining groove 121. When the fixing plate 12 is mounted on the mounting plate 11, the protrusion 111 engages the sealing ring, thereby forming a seal and reducing air leakage at the connection between the fixing plate 12 and the mounting plate 11. Furthermore, the sealing ring increases friction, preventing the fixing plate 12 from rotating relative to the mounting plate 11 after installation.

[0125] Optionally, the movable plate 20 may be rotatably connected to the fixed plate 12. When the fixed plate 12 is disassembled, the movable plate 20 may be disassembled together.

[0126] In some examples, the fixing plate 12 and the mounting plate 11 may also be an integral structure, that is, a whole.

[0127] Illustratively, the fixing plate 12 and the mounting plate 11 are a single piece of injection-molded part, or the fixing plate 12 can also be manufactured as a whole with the mounting plate 11 through insert molding.

[0128] Of course, in other examples, the baffle 10 can also be a metal part, which can have a higher structural strength. For example, one of the fixing plate 12 and the mounting plate 11 is a metal part; for another example, the fixing plate 12 and the mounting plate 11 are both metal parts.

[0129] Figure 19 is a schematic diagram of the structure of a front bumper assembly provided in an embodiment of the present application. As shown in Figure 19, the front bumper assembly includes a bumper cover 1601 and an air intake grille 1602. The air intake grille 1602 is connected to the bumper cover 1601. The air intake grille 1602 can be any of the air intake grilles 1602 shown in Figures 1 to 18.

[0130] The air intake grille 1603 can be arranged on a side of the bumper skin 1601 close to the car engine. The bumper skin 1601 usually has an air intake structure such as a grid, and the grid is opposite to the air intake grille 1602.

[0131] In some examples, the baffle 10 of the air intake grille 1602 can be an integral structure with the bumper skin 1601, that is, the air intake 10a is directly arranged on the bumper skin 1601. This can make the structure of the front bumper assembly more compact.

[0132] As shown in Figure 19, a headlight 1603 may be provided on the bumper cover 1601. The size, shape, and position of the headlight 1603 on the bumper cover 1601 may be adjusted based on the specific vehicle model. Figure 19 is merely an illustration.

[0133] The present application also provides a vehicle, which may include any of the air intake grilles shown in Figures 1 to 18, and may also include a front bumper assembly as shown in Figure 19. The vehicle may be, but is not limited to, a car, an electric car, or a hydrogen-powered car.

[0134] The above description is only one embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
