Description

Technical Field

[0001] The present application relates to the technical field of vehicle components, and more particularly, to a variable intake device for a vehicle and a vehicle. Background Art

[0002] As one of the important intake devices of a vehicle, the intake grille is generally located directly in front of the vehicle head, and its main functions are to provide intake and heat dissipation for heat-generating components such as the engine or / and the motor. On general vehicle models, the intake opening of the intake grille is always open. The advantage of this is that as long as the vehicle starts, the heat-generating components such as the engine or / and the motor will receive the maximum heat dissipation power, which is an advantage in hot summer. However, in cold winter, it may not necessarily be a good thing. If the intake opening is not closed, when driving a cold vehicle, the air entering from the intake opening will also cool the radiator with a not-high temperature, which directly causes the water temperature to rise slowly and affects the engine to enter the best working state faster. Therefore, the heating effect of some vehicle models is poor in winter, and this is one of the reasons.

[0003] In addition to the intake grille in front of the vehicle head, similar intake devices are often required at other positions of the vehicle, such as the hood intake device, the front bumper intake device, the deflector in front of the radiator, the engine intake device, the air filter intake device, the intake device of the turbocharging system, the intake device of the brake system cooling air duct, the intake device related to vehicle dust and water protection, etc. In the related art, the size or opening / closing condition of the intake opening of some of the above intake devices is adjusted by the movement of the blade; however, the blade usually closes or opens the intake opening in a flipping manner. In order to flip the blade, a blade driving mechanism and a transmission structure directly connected to the blade need to be equipped. Since the blade needs to flip, no matter which side of the blade the transmission structure is connected to, there is generally a problem that the transmission structure is exposed at the intake opening, resulting in poor appearance consistency of the intake device and being not beautiful. Secondly, after the transmission structure is exposed at the intake opening, it will also hinder the intake volume to a certain extent. In addition, for such a flipping blade, when it opens the intake opening to the maximum extent, it is also exposed at the intake opening, and the intake volume of the intake opening is limited. And in order to prevent the blade from occupying too much space in the vehicle in the through direction of the intake opening when flipping, the width of the blade is generally narrow, so multiple blades may be required for one intake opening, which further limits the intake volume of the intake opening. Summary of the Invention

[0004] To solve the above problems, the present application provides a variable intake device for a vehicle, which includes an intake plate and an opening / closing mechanism. The intake plate is provided with a through intake port, and the opening / closing mechanism is arranged inside the intake plate, and the opening / closing mechanism includes blades and a driving device; the blades are hinged to the intake plate, and the hinge axis of the blades is parallel to the through direction of the intake port; the driving device is in transmission connection with the blades and is used to drive the blades to rotate around their hinge axis so that the blades close or open the intake port.

[0005] In the variable intake device of the vehicle, by designing the hinge axis of the blades to be parallel to the through direction of the intake port, that is to say, the blades can rotate in a plane parallel to the intake plate, and the plate surface of the blades is parallel to the plate surface of the intake plate. Furthermore, the driving device drives the blades to rotate around the hinge axis in the plane where their plate surfaces are located to open or close the intake port. Through such blades that rotate in the plane where their own plate surfaces are located, the additional space occupied by the blades in the through direction of the intake port during the movement process can be reduced; in addition, both the blades and the driving device are located inside the intake plate. Therefore, after the blades rotate to open the intake port, they can completely stagger the intake port and will not be exposed at the intake port, and users will not see the blades from the intake port. The driving mechanism located inside the intake plate is connected to the blades, and the movement mode of the blades is to rotate in the plane where their own plate surfaces are located, rather than a flipping motion. Therefore, the connection position of the driving device and the blades can always be inside the intake plate and / or the blades and will not be exposed to the user's field of vision, and the consistency of the intake plate is better and the aesthetics is stronger; in addition, since the blades can completely stagger the intake port when rotating in the plane where their own plate surfaces are located, the maximum intake volume of the intake port can be guaranteed, and the maximum intake volume of the intake port will not be limited.

[0006] Further, at least three blades are provided, and at least three blades are sequentially distributed around the center line of the intake port, and the driving device is used to drive a plurality of the blades to rotate simultaneously to close or open the intake port.

[0007] Further, the edge of each blade includes an adjacent convex arc side and a concave arc side; the centers of the convex arc sides of the blades are all located on a first set circle, and the centers of the concave arc sides of the blades are all located on a second set circle; when the intake port is in a closed state, the first set circle coincides with the second set circle.

[0008] Further, the blades are hinged to the intake plate through a hinge shaft. The edge of the blade further includes an outer side located between the convex arc side and the concave arc side. The axis of the hinge shaft is located at the connection position of the concave arc side and the outer side, and a relief notch is provided at a portion of the convex arc side close to the outer side.

[0009] Further, the hinge axes of the blades are all located on a third set circle, and the third set circle surrounds the air inlet. When the air inlet is in a closed state, the avoidance notch is located outside the edge of the air inlet.

[0010] Further, the driving device includes an annular member, a plurality of connecting rods and a power member. The annular member is rotatably connected to the air inlet plate around its axis and surrounds the air inlet, and the axis of the annular member is collinear with the center line of the air inlet. The plurality of connecting rods are arranged at intervals along the circumference of the annular member. One end of each connecting rod is hinged to the annular member, and the other end of each connecting rod is hinged to the corresponding blade. The power member is relatively fixed to the air inlet plate, and the power member is used to drive the annular member to rotate.

[0011] Further, the annular member surrounds the blade, the connecting rod is an arc-shaped rod, and the hinge axis of the blade corresponding to the arc-shaped rod and the center of the arc-shaped rod are on the same side of the arc-shaped rod.

[0012] Further, the driving device further includes a gear, the power member is a motor, the annular member is provided with a tooth structure along its circumference, the output shaft of the motor is in transmission connection with the gear, and the gear meshes with the tooth structure.

[0013] Further, the variable air intake device of the vehicle further includes a suction device. The suction device is connected to the inner side of the air inlet plate and is disposed opposite to the air inlet. Wherein, in the through direction of the air inlet, the blade is located between the suction device and the air inlet plate.

[0014] This application also provides a vehicle, including the variable air intake device of the vehicle as described above.

Detailed implementation manners

[0026] To make the above objects, features and advantages of the present application more obvious and understandable, the following detailed description of the specific embodiments of the present application is given with reference to the accompanying drawings.

[0027] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "rear", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0028] Moreover, in the drawings, the X-axis represents the longitudinal direction, and the positive direction of the X-axis represents the front, and the negative direction of the X-axis represents the rear; the Y-axis represents the transverse direction, and the positive direction of the Y-axis represents the left, and the negative direction of the Y-axis represents the right; the Z-axis represents the vertical direction, that is, the up and down direction, and the positive direction of the Z-axis represents the up, and the negative direction of the Z-axis represents the down.

[0029] It should be noted that the meanings represented by the aforementioned X-axis, Y-axis, and Z-axis are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the indicated devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0030] Refer to Figures 1-3 The present application provides a variable intake device for a vehicle, including an intake plate 1 and an opening / closing mechanism. A through intake port 11 is provided on the intake plate 1. The opening / closing mechanism is disposed inside the intake plate 1, and the opening / closing mechanism includes a blade 2 and a driving device. The blade 2 is hinged to the intake plate 1, and the hinge axis of the blade 2 is parallel to the through direction of the intake port 11. The driving device is in transmission connection with the blade 2 and is used to drive the blade 2 to rotate around its hinge axis so that the blade 2 closes or opens the intake port 11.

[0031] In this embodiment, by designing the hinge axis of the blade 2 to be parallel to the through direction of the intake port 11, that is, the blade 2 can rotate in a plane parallel to the intake plate 1, and the plate surface of the blade 2 itself is parallel to the plate surface of the intake plate 1. Furthermore, the driving device drives the blade 2 to rotate around the hinge axis in the plane where its plate surface is located to open or close the intake port 11. With the blade 2 rotating in the plane where its own plate surface is located, the additional space occupied by the blade 2 in the through direction of the intake port 11 during movement can be reduced. In addition, both the blade 2 and the driving device are located inside the intake plate 1. Therefore, after the blade 2 rotates to open the intake port 11, it can be completely staggered from the intake port 11 and will not be exposed at the intake port 11, and the user cannot see the blade 2 from the intake port 11. The driving mechanism located inside the intake plate 1 is connected to the blade 2, and the movement mode of the blade 2 is to rotate in the plane where its own plate surface is located, rather than a flipping movement. Therefore, the connection position between the driving device and the blade 2 can always be inside the intake plate 1 and / or the blade 2 and will not be exposed to the user's view, and the consistency of the intake plate 1 is better and the aesthetics is stronger. In addition, since the blade 2 can completely stagger the intake port 11 when rotating in the plane where its own plate surface is located, the maximum intake volume of the intake port 11 can be ensured, and the maximum intake volume of the intake port 11 will not be limited.

[0032] Among them, the variable intake device can be an intake grille at the front end of the vehicle, an engine hood intake device, a front bumper intake device, a deflector plate in front of the radiator, an engine intake device, an air filter intake device, an intake device of a turbocharging system, an intake device of a brake system cooling air duct, an intake device related to vehicle dust and water prevention, etc.

[0033] In this application, for the convenience of describing the orientation of each component in the variable intake device, the variable intake device is exemplified below by an intake grille located at the front end of the vehicle. On this basis, the penetration direction of the air inlet 11 on the intake plate 1 refers to the longitudinal direction of the vehicle, that is, the air inlet 11 penetrates the intake plate 1 in the longitudinal direction of the vehicle. By designing the hinge axis of the blade 2 to be parallel to the penetration direction of the air inlet 11, the blade 2 that rotates in the plane of its own plate surface can reduce the additional occupation of the longitudinal space of the vehicle during the movement of the blade 2; in addition, both the blade 2 and the driving device are located inside the intake plate 1, that is, on the rear side of the intake plate 1. Therefore, after the blade 2 rotates to open the air inlet 11, it can completely stagger the air inlet 11 and will not be exposed at the air inlet 11. The external personnel of the vehicle cannot see the blade 2 of the intake grille. The driving mechanism located inside the intake plate 1 is connected to the blade 2, and the movement mode of the blade 2 is to rotate in the plane of its own plate surface, rather than a flipping movement. Therefore, the position where the driving device is connected to the blade 2 can always be inside the intake plate 1 and / or the blade 2 and will not be exposed to the vision of the external personnel of the vehicle, and the consistency of the intake grille is better and the aesthetics is stronger.

[0034] In addition, in the related art, the air inlet 11 of the intake grille is generally rectangular, and the blade 2 is strip-shaped, with a single shape. In this embodiment, the shape of the air inlet 11 is not limited, and the number and shape of the blades 2 corresponding to one air inlet 11 are also not limited. The shape of the air inlet 11 can be the circular shape shown in the figure, or a regular polygon, a rectangle, etc.; the number of the blades 2 can be one or multiple, and as long as the shape of the blade 2 satisfies that it can close or open the corresponding air inlet 11 after rotating in the plane of its own plate surface.

[0035] See Figures 1-3 , optionally, at least three blades 2 are provided, and at least three blades 2 are sequentially distributed around the center line of the air inlet 11, and the driving device is used to simultaneously drive a plurality of blades 2 to rotate to close or open the air inlet 11.

[0036] In this embodiment, the number of blades 2 corresponding to one air inlet 11 can be at least three, and these blades 2 are distributed successively around the center line of the air inlet 11. The driving device drives these blades 2 to rotate together, so as to open or close the air inlet 11 jointly. Compared with a single blade 2, by arranging at least three blades 2, the size of a single blade 2 can be reduced, and the size of a single blade 2 can be designed to be smaller. Accordingly, the space required for the rotation of a single blade 2 itself during the rotation process is also relatively small. In the case where these blades 2 are distributed successively around the center line of the air inlet 11, only a relatively small movement space around the air inlet 11 of the air inlet plate 1 needs to be ensured to meet the rotation space requirements of these smaller-sized blades 2. On this basis, in the case where the air inlet plate 1 is provided with a plurality of air inlets 11, in all directions, the interval size between adjacent air inlets 11 does not need to be large, so as to ensure that as many air inlets 11 as possible can be designed on the air inlet plate 1 on the premise of a certain-sized air inlet plate 1.

[0037] It should be noted that, as Figure 9 shown, in the case where the air inlet plate 1 is provided with a plurality of air inlets 11, the shapes of the air inlets 11 can be the same or different. Some air inlets 11 can be equipped with opening and closing mechanisms, and some air inlets 11 can be of a normally open structure (not equipped with an opening and closing mechanism and always in an open state). For example, the shapes of some air inlets 11 are circular, and the shapes of other air inlets 11 are rectangular; even when the driving device in the opening and closing mechanism drives the blade 2 to close the corresponding air inlet 11, the normally open air inlets 11 can still meet the air intake requirements under the relatively low cooling capacity demand of the whole vehicle; and when the normally open air inlets 11 alone cannot meet the cooling capacity demand of the whole vehicle, the air inlets 11 equipped with opening and closing mechanisms can be opened by the opening and closing mechanisms to increase the air intake.

[0038] Referring to Figures 5-8 , optionally, the edge of each blade 2 includes adjacent convex arc sides 21 and concave arc sides 22; the centers of the convex arc sides 21 of the blades 2 are all located on a first set circle S1, and the centers of the concave arc sides 22 of the blades 2 are all located on a second set circle S2; when the air inlet 11 is in a closed state, the first set circle S1 coincides with the second set circle S2.

[0039] Among them, when the air inlet 11 is in a closed state, it specifically means that when the air inlet 11 is in a state of being closed by the blade 2, which is equivalent to when the blade 2 is in a state of closing the air inlet 11.

[0040] Specifically, the center of the convex arc side 21 is the center of a circle where the convex arc side 21 is located. The centers of the convex arc sides 21 of the blades 2 are all located on the first set circle S1. The center of the first set circle S1 can be located on the center line of the air inlet 11. When these blades 2 rotate synchronously, the centers of the convex arc sides 21 of the blades 2 also move synchronously. Furthermore, the diameter of the first set circle S1 will increase or decrease as these blades 2 rotate synchronously. Similarly, the center of the second set circle S2 can also be located on the center line of the air inlet 11, and the diameter of the second set circle S2 will also increase or decrease as these blades 2 rotate synchronously.

[0041] In this embodiment, when the air inlet 11 is in a closed state, the convex arc side 21 of one of the adjacent blades 2 matches the concave arc side 22 of the other, that is, at this time, the centers of the convex arc side 21 of one of the adjacent blades 2 and the concave arc side 22 of the other are at the same point. Furthermore, for all the blades 2, the centers of all the convex arc sides 21 and the centers of the concave arc sides 22 are located on the same circle, that is, the first set circle S1 and the second set circle S2 coincide, as Figure 6 shown. In this way, interference between any two adjacent blades 2 during rotation and closing can be avoided, and a gap between any two adjacent blades 2 can be eliminated when they are in a fully closed state (when the convex arc side 21 of the adjacent blades 2 is in contact with the concave arc side 22, there is no gap between them), and finally the air inlet 11 can be completely closed.

[0042] In addition, as Figure 1 shown, when these blades 2 jointly close the air inlet 11, the blade assembly formed by these blades 2 presents a flower-like shape from the perspective outside the vehicle. Compared with the shutter shape in the related art, the shape presented by the multiple blades 2 after the air inlet 11 is closed in this embodiment is more beautiful, subverting the shape of the traditional air grille, and the vehicle appearance is better.

[0043] Referring to Figures 5-8 , optionally, the blade 2 is hinged to the air inlet plate 1 through a hinge shaft 3. The edge of the blade 2 further includes an outer side 23 located between the convex arc side 21 and the concave arc side 22. The axis of the hinge shaft 3 is located at the connection position of the concave arc side 22 and the outer side 23, and an avoidance notch 211 is provided at a part of the convex arc side 21 close to the outer side 23.

[0044] In this embodiment, in addition to the convex arc side 21 and the concave arc side 22 for cooperating with adjacent blades 2, the blade 2 further includes an outer side 23 located between the convex arc side 21 and the concave arc side 22. The blade 2 surrounded by the convex arc side 21, the concave arc side 22, and the outer side 23 is similar to a triangular shape. When the air inlet 11 is in the closed state, the connection point of the convex arc side 21 and the concave arc side 22 of each blade can be located on the central axis of the air inlet 11, and the outer side 23 is located outside the air inlet 11, so that the air inlet 11 is completely covered by these blades 2. The corner formed by the outer side 23 and the concave arc side 22 is hinged to the air inlet plate 1 through a hinge shaft 3, which can ensure that the entire blade 2 is basically on one side of the hinge shaft 3. In this way, when the blade 2 rotates around the axis of the hinge shaft 3, it only needs to ensure that the convex arc side 21 of the blade 2 does not interfere with the hinge shaft 3 of the adjacent blade 2. In order to ensure that adjacent blades 2 do not interfere with each other during rotation, an avoidance notch 211 is provided at a portion of the convex arc side 21 close to the outer side 23, so that the blade 2 can avoid the hinge shaft 3 of the adjacent blade 2 during rotation and ensure that the blade 2 can rotate normally.

[0045] See Figure 6 , optionally, the hinge axes of the blades 2 are all located on a third set circle S3, and the third set circle S3 surrounds the air inlet 11. When the air inlet 11 is in the closed state, the avoidance notch 211 is located outside the edge of the air inlet 11.

[0046] In this embodiment, the hinge shaft 3 of each blade 2 is located outside the edge of the air inlet 11, that is, the third set circle S3 formed by the hinge axes of the blades 2 is located outside the edge of the air inlet 11. In this way, it can be ensured that when these blades 2 are in the state of closing the air inlet 11, the outer edge of the blade assembly composed of these blades 2 is located outside the air inlet 11, that is, the outer side 23 of each blade 2 can be located outside the air inlet 11, ensuring the effective shielding of the air inlet 11 by the blade assembly composed of these blades 2. And, in the closed state, the outer side 23 is located outside the air inlet 11 and has a certain distance from the edge of the air inlet 11, and a section where the convex arc side 21 is connected to the outer side 23 is also located outside the air inlet 11. By setting the avoidance notch 211 on a section of the convex arc side 21 located outside the air inlet 11, it can be ensured that the avoidance notch 211 in the closed state of the blade 2 is located outside the edge of the air inlet 11, ensuring that the external gas of the vehicle does not enter the inner side of the air inlet plate 1 from the avoidance notch 211; especially when the radius of the circle where the convex arc side 21 is located is the same as the radius of the circle where the concave arc side 22 is located (the convex arc side 21 and the concave arc side 22 of adjacent blades 2 are in contact in the closed state), it can be ensured that the external gas cannot enter the inner side of the air inlet plate 1 through the avoidance notch 211 between the convex arc side 21 and the concave arc side, and finally the sealing performance of these blades 2 after closing the air inlet 11 can be ensured.

[0047] See Figures 4-8 Figures 4-8 , optionally, the driving device includes an annular member 41, a plurality of connecting rods 42 and a power member 43. The annular member 41 is rotatably connected to the intake plate 1 about its axis and surrounds the intake port 11, and the axis of the annular member 41 is collinear with the center line of the intake port 11. The plurality of connecting rods 42 are arranged at intervals along the circumference of the annular member 41. One end of each connecting rod 42 is hinged to the annular member 41, and the other end of each connecting rod 42 is hinged to the corresponding blade 2. The power member 43 is relatively fixed to the intake plate 1, and the power member 43 is used to drive the annular member 41 to rotate.

[0048] In this embodiment, the axis of the annular member 41 is collinear with the center line of the intake port 11. First, it can ensure that the annular member 41 does not occupy too much space on one side of the intake port 11 (such as the upper space of the intake port 11). Secondly, since these blades 2 are distributed in sequence around the center line of the intake port 11, by rotating the annular member 41 around its axis, that is, the center line of the intake port 11, the annular member 41 and the plurality of connecting rods 42 can be centrosymmetric, which is convenient for driving these blades 2 to rotate synchronously through the plurality of connecting rods 42 and ensuring uniform stress on the plurality of connecting rods 42 and the corresponding blades 2.

[0049] See Figures 4-8 Figures 4-8 , optionally, the annular member 41 surrounds the blade 2, the connecting rod 42 is an arc-shaped rod, and the hinge axis of the corresponding blade 2 of the arc-shaped rod and the center of the arc-shaped rod are on the same side of the arc-shaped rod.

[0050] In this embodiment, the annular member 41 surrounds these blades 2 and there is space for these blades 2 to rotate and open between them. The connecting rod 42 for connecting the annular member 41 and the blade 2 can be an arc-shaped rod. One end of the arc-shaped rod can be hinged to the connecting part of the outer side edge 23 and the convex arc side edge 21 of the blade 2, and the convex direction of the arc-shaped rod has a special design, that is, the hinge axis of the corresponding blade 2 of the arc-shaped rod and the center of the arc-shaped rod are on the same side of the arc-shaped rod. In other words, the convex direction of the arc-shaped rod is away from the hinge axis 3 of the corresponding blade 2. In this way, when the annular member 41 rotates, the rotation torque can be transmitted to the blade 2 along the arc direction of the arc-shaped rod, ensuring that more force is transmitted to the blade 2 and less force is lost during the transmission process. It can make the power member 43 only need to output a small amount of power to drive the blade 2 to rotate, and can reduce the stress on the connecting rod 42 and improve the service life of the connecting rod 42.

[0051] See Figures 4-8, optionally, the driving device further includes a gear 44, the power member 43 is a motor, the annular member 41 is provided with a tooth structure 411 along its circumferential direction, the output shaft of the motor is in transmission connection with the gear 44, and the gear 44 meshes with the tooth structure 411.

[0052] In this embodiment, the power member 43 may specifically be a motor, which is controlled by a vehicle controller. When the motor rotates, it drives the gear 44 in transmission connection with it to rotate. The rotating gear 44 drives the annular member 41 to rotate through cooperation with the tooth structure 411, with a simple and efficient structure. Among them, the tooth structure 411 may be obtained by machining the annular member 41, or the tooth structure 411 may be an arc-shaped rack fixed on the annular member 41. The tooth structure 411 may be located on the outer peripheral side of the annular member 41, and after meshing with the gear 44, it will not affect the movement of the connecting rod 42.

[0053] Optionally, referring to Figure 4 , the variable intake device of the vehicle further includes a suction device 5. The suction device 5 is connected to the inner side of the intake plate 1 and is disposed opposite to the intake port 11. Among them, in the through direction of the intake port 11, the blade 2 is located between the suction device 5 and the intake plate 1.

[0054] In this embodiment, a suction device 5, such as a fan, is further fixed to the inner side of the intake plate 1, and the fan is disposed opposite to the intake port 11. The aforementioned blade 2 is located between the fan and the intake port 11. Thus, when the blade 2 opens the intake port 11, on the basis of enabling natural intake of the intake port 11, the intake volume of the intake port 11 can be actively increased by the operation of the fan.

[0055] In this embodiment, the outer side of the housing of the fan may be protrudingly provided with lugs 51, and the lugs 51 can be connected to the intake plate 1 by bolts to realize the fixation of the fan. At the same time, the housing of the fan may also be connected to a support plate 45 parallel to the intake plate 1, and the support plate 45 is used to carry and install the aforementioned power member 43, and the support plate 45 can also be connected and fixed to the intake plate 1 by bolts.

[0056] As described above, as Figure 9As shown, when there are multiple air inlets 11 provided on the air intake plate 1, some of the air inlets 11 can be equipped with opening and closing mechanisms, and some of the air inlets 11 can be of a normally open structure (without an opening and closing mechanism and always in an open state). Even when the driving device in the opening and closing mechanism drives the blade 2 to close the corresponding air inlet 11, the normally open air inlet 11 can still meet the air intake requirement of the vehicle under the condition of relatively low cooling capacity of the whole vehicle; and when the air intake requirement of the whole vehicle cannot be met only by the normally open air inlet 11, the air inlet 11 equipped with an opening and closing mechanism can be opened by the opening and closing mechanism to increase the air intake volume of the variable air intake device of the vehicle; if the air intake volume of the variable air intake device of this vehicle is still insufficient when the opening and closing mechanism opens the corresponding air inlet 11, the fan can be operated at an appropriate speed to forcibly increase the air intake volume of the corresponding air inlet 11 to ensure that the air intake requirement of the whole vehicle can be met. It should be noted that when the air inlet 11 is equipped with a fan, the normally open air inlet 11 may not be provided on the air intake plate 1, but only the air inlet 11 equipped with an opening and closing mechanism and a fan is provided.

[0057] Another embodiment of the present application further provides a vehicle, including the variable air intake device of the vehicle as described above.

[0058] Since the technical improvement and technical effect of the vehicle are the same as those of the variable air intake device of the vehicle, the vehicle will not be described in detail herein.

[0059] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

[0060] Although the present application is disclosed as above, the protection scope of the present application is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application, and these changes and modifications will all fall within the protection scope of the present application.
