Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a front grille assembly and a vehicle. Background Technology

[0002] In related technologies, active grille assemblies are typically located behind the front grille of a vehicle. These assemblies include blades that can move between a closed position and an open position to close or open openings in the front grille. However, active grille assemblies in related technologies are less effective at reducing vehicle drag when closed. Therefore, how to reduce vehicle drag when the active grille assembly is closed has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0003] In view of this, the purpose of this application is to provide a front grille assembly to reduce the vehicle's wind resistance when the active air intake grille assembly is closed.

[0004] Another object of this application is to provide a vehicle including the aforementioned front grille assembly.

[0005] To achieve the above objectives, this application provides the following technical solution: A front grille assembly, comprising: A vehicle front grille, wherein the vehicle front grille is provided with grille openings; An active air intake grille assembly includes blades and a drive mechanism. A blocking block is provided on the blade, and the shape of the blocking block is adapted to the grille opening. The drive mechanism is connected to the blade and is used to drive the blade to move between a closed position and an open position. In the closed position, the sealing block is embedded in at least a portion of the grille opening of the vehicle's front grille; in the open position, both the blade and the sealing block avoid the grille opening.

[0006] In some embodiments, at least a portion of the grille openings of the vehicle's front grille are provided with resilient seals; In the closed position, the blade is in contact with the resilient seal.

[0007] In some embodiments, the active air intake grille assembly includes a grille base fixed to the back of the vehicle's front grille, and the blades and the drive mechanism are both disposed on the grille base; Both ends of the blade are provided with a blade sliding rod and a blade traction rod. A slide rail is provided on the grid base. The blade sliding rod passes through the slide rail and slides in cooperation with the slide rail. The blade is connected to the drive mechanism through the blade traction rod. The slide rail includes a translation section and a rotation section that are interconnected and arranged at an angle. When the blade moves from the closed position to the open position, the blade sliding rod first moves along the translation section and then enters the rotation section. The translation section is used to make the blocking block exit from the grid opening. The rotation section changes the movement direction of the blade sliding rod to drive the blade to rotate, so that both the blade and the blocking block avoid the grid opening.

[0008] In some embodiments, the blade traction rod passes through the slide rail and slides in cooperation with the slide rail.

[0009] In some embodiments, the blades are multiple; The drive mechanism includes a drive motor and a transmission linkage mechanism. The drive motor is mounted on the grid base, and the transmission linkage mechanism is mounted on the grid base and connected between the drive motor and the blade traction rod of each blade, for converting the rotational motion of the drive motor into the synchronous movement of each blade.

[0010] In some embodiments, the transmission linkage mechanism includes a driving link, a driven link, a master-slave connecting link, a crank connecting link, and a blade synchronizing link; Both the active rod and the driven rod are rotatably mounted on the grid base, and the active rod and the driven rod are arranged in parallel. The drive motor is connected to the active rod and is used to drive the active rod to rotate. The master-slave linkage connects the driving rod and the driven rod so that when the driving rod rotates, it drives the driven rod to rotate synchronously. There are multiple crank connecting rods, one end of each crank connecting rod is rotatably connected to the driving rod or the driven rod, and the other end is rotatably connected to the blade synchronizing rod; The blade synchronizing rod is rotatably connected to the blade traction rod of each blade, and is used to drive the blade traction rod of each blade to move synchronously.

[0011] In some embodiments, the driving rod is provided with a driving rod synchronizing rod, and the driven rod is provided with a driven rod synchronizing rod; One end of the master-slave linkage is rotatably connected to the driving linkage synchronizing rod, and the other end is rotatably connected to the driven linkage synchronizing rod, so that the driving rod, the driving linkage synchronizing rod, the master-slave linkage, and the driven linkage synchronizing rod form a four-bar linkage mechanism; The driving rod is provided with a driving rod crank, and the driven rod is provided with a driven rod crank; Each of the crank connecting rods is rotatably connected to the driving rod via the driving rod crank, or rotatably connected to the driven rod via the driven rod crank.

[0012] In some embodiments, the grille base is fixed to the back of the vehicle's front grille by a mounting structure or ultrasonic welding.

[0013] In some embodiments, the grille opening includes a sealing hole and a vent hole, the sealing hole being located on both sides of the front grille of the vehicle, and the vent hole being located in the middle area of ​​the front grille of the vehicle. The sealing block is used to embed into the sealing hole, and the vent hole remains open.

[0014] A vehicle includes a body and a front grille assembly, the front grille assembly being any of the aforementioned front grille assemblies, the front grille assembly being disposed at the front of the body.

[0015] The front grille assembly provided in this application includes a vehicle front grille and an active air intake grille assembly. The vehicle front grille has grille openings through which air can flow. The active air intake grille assembly includes blades and a drive mechanism. A blocking block is provided on the blades. The drive mechanism is connected to the blades and drives the blades to move between a closed position and an open position. In the closed position, the blocking block is embedded in at least a portion of the grille opening of the vehicle front grille, the shape of the blocking block being adapted to the shape of the grille opening so that the blocking block can enter the grille opening and block the opening. In the open position, both the blades and the blocking block avoid the grille opening, allowing air to flow through the grille opening. Because the blocking block is embedded in the grille opening of the vehicle front grille in the closed position, the blocking block is located at the grille opening, thus making the blocking structure closer to the outer surface of the vehicle front grille in the closed state. This helps optimize the airflow path through the front grille, thereby reducing vehicle drag.

[0016] The vehicle provided in this application includes the aforementioned front grille assembly, and therefore also possesses the aforementioned structure and beneficial effects. Other structures are described in reference to relevant technologies and will not be repeated here. Attached Figure Description

Detailed Implementation

[0020] In related technologies, the front grille assembly typically places the active air intake grille assembly behind the vehicle's front grille, using the movement of blades to open and close the grille openings. However, in the closed state, the active air intake grille in these technologies is less effective at reducing wind resistance, making it difficult to meet the increasingly demanding requirements for fuel economy and aerodynamic performance.

[0021] Based on this, this application provides a front grille assembly and a vehicle. The front grille assembly includes a vehicle front grille and an active air intake grille assembly. The active air intake grille assembly includes blades and a drive mechanism. A blocking block is disposed on the blade. By embedding the blocking block into at least a portion of the grille openings of the vehicle front grille in the closed position, the blocking block directly participates in blocking the grille openings, thereby improving the airflow blocking effect in the closed state and helping to reduce vehicle wind resistance.

[0022] The basic embodiments of this application will now be described with reference to the accompanying drawings.

[0023] In this application, "multiple" refers to two or more. "Connection," "installation," and "fitting" should be interpreted broadly, encompassing fixed connections, detachable connections, integral connections, and direct or indirect connections. "Synchronous movement" or "synchronous rotation" refers to a definite kinematic relationship, not limited to identical speeds, as long as the movements are coordinated according to a predetermined transmission relationship. "Responding to" is used to specify the triggering condition of the action, but does not exclude the existence of other triggering conditions. In this application, the "back" of the vehicle's front grille refers to the side of the vehicle's front grille facing away from the vehicle's exterior, i.e., the side of the vehicle's front grille closest to the engine compartment; the "outer surface" of the vehicle's front grille refers to the surface of the vehicle's front grille facing the vehicle's exterior. Accordingly, "front" or "forward" in this application refers to the direction facing the vehicle's exterior, and "rear" or "rearward" refers to the direction facing the engine compartment.

[0024] See Figures 1 to 3 The front grille assembly disclosed in this application includes a vehicle front grille 100 and an active air intake grille assembly. The vehicle front grille 100 is provided with grille openings 110 through which air can flow. The active air intake grille assembly includes blades 200 and a drive mechanism 300. A blocking block 210 is provided on the blades 200. The drive mechanism 300 is connected to the blades 200 and is used to drive the blades 200 to move between a closed position and an open position. In the closed position, the blocking block 210 is embedded in at least a portion of the grille opening 110 of the vehicle front grille 100, and the shape of the blocking block 210 is adapted to the shape of the grille opening 110 so that the blocking block 210 can enter the grille opening 110 and block the opening. In the open position, both the blades 200 and the blocking block 210 avoid the grille opening 110, allowing air to flow through the grille opening 110.

[0025] Since the sealing block 210 is embedded in the grille opening 110 of the vehicle's front grille 100 in the closed position, the sealing block 210 is located at the grille opening 110, so that the sealing structure in the closed state is closer to the outer surface of the vehicle's front grille 100, which is conducive to optimizing the airflow path through the front grille and thus reducing the vehicle's wind resistance.

[0026] Combination Figure 2The grille opening 110 may specifically include a blocking opening 111 controlled by an active air intake grille and a vent 112 not controlled by an active air intake grille. Air can flow through the vent 112. A blocking block 210 is embedded in the blocking opening 111, and the vent 112 remains open. For example, the vent 112 may be located in the middle region of the vehicle's front grille 100, and the blocking opening 111 may be located on either side of the vehicle's front grille 100. The vent 112 is never blocked by the blades 200, while the blocking opening 111 is blocked by the blocking blocks 210 on the corresponding blades 200. With this arrangement, when the vehicle's front grille 100 is closed, only the blocking openings 111 on both sides are blocked, while the vent 112 in the middle region remains open, which helps to balance aesthetic consistency and air intake requirements.

[0027] Furthermore, in some implementations, combined with Figure 4 At least a portion of the grille openings 110 of the vehicle's front grille 100 are surrounded by elastic seals 120. Specifically, elastic seals 120 are provided around sealing holes 111, while elastic seals 120 may not be provided around vent holes 112. In the closed position, the blades 200 are compressed and fitted with the elastic seals 120. The elastic seals 120 are disposed around the back of the sealing holes 111, the back of the grille openings 110 is flat, and the elastic seals 120 are evenly distributed around the sealing holes 111. Exemplarily, the elastic seals 120 can be sealing soft rubber, sealing strips, sealing rings, or sealing gaskets disposed around the sealing holes 111. The material of the elastic seals 120 can be elastic sealing materials such as rubber, silicone, or thermoplastic elastomers. The elastic seals 120 can be fixed to the back of the vehicle's front grille 100 by injection molding, bonding, or snap-fitting. When the blade 200 moves from the open position to the closed position, the sealing block 210 is inserted into the sealing hole 111, and the flat portion of the blade 200 contacts and compresses the elastic seal 120, thereby forming a seal at the sealing hole 111. Because of the elastic seal 120 and the compressed fit between the blade 200 and it in the closed position, the sealing effect at the sealing hole 111 is improved, reducing air leakage in the closed state.

[0028] Combination Figure 8 The blade 200 is a long, narrow baffle with a U-shaped cross-section. The front surface of the blade 200 is flat, or for example, a flat curved surface. A sealing block 210 is disposed on the front surface of the blade 200. The sealing block 210 and the blade 200 can be integrally molded, for example, by injection molding or stamping; alternatively, the sealing block 210 can be separately molded and then assembled onto the blade 200, for example, by snap-fitting, welding, bonding, or fasteners to the front surface of the blade 200. The flat surface of the blade 200, in the closed position, compresses and adheres to the elastic seal 120, which helps improve the sealing effect.

[0029] See Figures 5 to 7 The active grille assembly also includes a grille base 400, which is fixed to the back of the front grille 100 of the vehicle. Blades 200 and a drive mechanism 300 are both mounted on the grille base 400. Each blade 200 is an elongated baffle, with a blade sliding rod 220 and a blade traction rod 230 at both ends along its length. A slide rail 410 is provided on the grille base 400, arranged in pairs, with each pair corresponding to one blade 200. The blade sliding rod 220 passes through the slide rail 410 and slides in cooperation with it. The slide rail 410 has a trajectory that causes the blade 200 to move backward and then rotate when moving from the closed position to the open position. The backward movement is used to disengage the sealing block 210 from the sealing hole 111, and the rotation is used to allow the blade 200 and the sealing block 210 to avoid the grille opening 110. The blade 200 is connected to the drive mechanism 300 via the blade traction rod 230, so that it can move back and forth under the drive of the drive mechanism 300.

[0030] Specifically, the slide 410 includes a translation section 411 and a rotation section 412 that are interconnected and arranged at an angle. When the blade 200 moves from the closed position to the open position, the blade sliding rod 220 first moves along the translation section 411 and then enters the rotation section 412. The translation section 411 corresponds to the backward translation of the blade 200, causing the sealing block 210 to exit from the sealing hole 111; the rotation section 412 corresponds to the rotation of the blade 200, which can change the direction of movement of the blade sliding rod 220, thereby allowing the blade 200 and the sealing block 210 to avoid the grid opening 110. Since the slide 410 is divided into the translation section 411 and the rotation section 412, the blade sliding rod 220 first translates and then rotates in the slide 410, allowing the blade 200 to exit the sealing hole 111 first and then rotate to open, avoiding interference between the sealing block 210 and the grid opening 110 during the exit process. Both the translation section 411 and the rotation section 412 can be straight grooves. The translation section 411 extends along the front-rear direction of the vehicle, and the rotation section 412 is arranged at an angle to the translation section 411 and is connected to the translation section 411 at the connection point, so that the slide 410 is in the shape of a broken line. The slide 410 has a simple structure, is easy to process, and can reliably realize the movement process of the blade 200 first translating and then rotating.

[0031] Furthermore, the blade traction rod 230 is also inserted into the slide rail 410 and slides in cooperation with the slide rail 410. At the same time, the part of the blade traction rod 230 that extends out of the slide rail 410 is connected to the drive mechanism 300. By inserting both the blade traction rod 230 and the blade sliding rod 220 into the slide rail 410, the blade 200 is constrained by the slide rail 410 during its forward and backward movement and rotation, making the movement more stable. Meanwhile, the blade traction rod 230 extending out of the slide rail 410 facilitates its connection with the drive mechanism 300 to receive driving force and drive the blade 200 to move forward and backward.

[0032] In some embodiments, there are multiple blades 200, divided into a left blade group and a right blade group. The left blade group corresponds to the sealing hole 111 on the left, and the right blade group corresponds to the sealing hole 111 on the right. Each of the left and right blade groups includes multiple blades 200 spaced apart along the vehicle height direction. Each blade 200 moves synchronously to seal the corresponding sealing hole 111. The drive mechanism 300 includes a drive motor 310 and a transmission linkage mechanism 320. The drive motor 310 is mounted on the grille base 400. The transmission linkage mechanism 320 is mounted on the grille base 400 and connects the drive motor 310 and the blade traction rod 230 of each blade 200, for converting the rotational motion of the drive motor 310 into the synchronous motion of each blade 200. By driving multiple blades 200 to move synchronously with one drive motor 310, the number of drive components is reduced, and the structure is simplified.

[0033] Specifically, the aforementioned transmission linkage mechanism 320 includes a driving rod 321, a driven rod 322, a master-slave connecting rod 323, a crank connecting rod 324, and a blade synchronizing rod 325. Both the driving rod 321 and the driven rod 322 are rotatably mounted on the grille base 400, and are arranged parallel to each other. The driving rod 321 is divided into a left driving rod and a right driving rod, each part being a cylindrical rod. A toothed key is provided at one end of each of the left and right driving rods near the center in the vehicle width direction, and is connected to the drive motor 310 via the toothed key. The drive motor 310 can be used to drive the driving rod 321 to rotate. The driving rod 321 and the driven rod 322 are connected via the master-slave connecting rod 323, so that when the driving rod 321 rotates, it drives the driven rod 322 to rotate synchronously. Multiple crank-connecting rods 324 are included, with one end of each crank-connecting rod 324 rotatably connected to either the driving rod 321 or the driven rod 322, and the other end rotatably connected to the blade synchronizing rod 325. The blade synchronizing rod 325 is located at both ends of the blade 200, and has multiple circular holes through which the blade traction rod 230 is inserted and rotated. The blade synchronizing rod 325 is rotatably connected to the blade traction rod 230 of each blade 200, driving the blade traction rod 230 of each blade 200 to move synchronously back and forth. Because the driving rod 321 and the driven rod 322 are arranged in parallel and synchronously connected via a master-slave connecting rod 323, the driving rod 321 and the driven rod 322 can rotate synchronously, thereby driving multiple blades 200 to move synchronously back and forth via the crank-connecting rods 324 and the blade synchronizing rods 325.

[0034] Specifically, see Figure 7 The grid base 400 is also provided with a rotating rod base 420 and a rotating rod cover plate 421. The rotating rod base 420 and the rotating rod cover plate 421 are respectively provided with the driving rod 321 and the driven rod 322. The rotating rod cover plate 421 covers the corresponding rotating rod base 420 and forms a cylindrical cavity with the rotating rod base 420. The driving rod 321 and the driven rod 322 are respectively inserted into their respective cylindrical cavities and can rotate relative to the grid base 400 around their own axis, while being restricted from axial movement. Through the cooperation of the rotating rod base 420 and the rotating rod cover plate 421, the driving rod 321 and the driven rod 322 can be stably installed on the grid base 400, ensuring both rotational freedom and restricting axial movement.

[0035] Furthermore, combined Figure 5 and Figure 6The driving rod 321 is provided with a driving rod synchronizing rod 321b and a driving rod crank 321a, and the driven rod 322 is provided with a driven rod synchronizing rod 322b and a driven rod crank 322a. Specifically, the driving rod 321 is provided with four pairs of driving rod cranks 321a and four pairs of driving rod synchronizing rods 321b, and the driven rod 322 is provided with four pairs of driven rod cranks 322a and four pairs of driven rod synchronizing rods 322b. The ends of the driving rod cranks 321a, driving rod synchronizing rods 321b, driven rod cranks 322a and driven rod synchronizing rods 322b are all provided with cylindrical pins. The driving crank 321a and the driven crank 322a are parallel and of equal length, and are respectively positioned at corresponding positions on the driving and driven rods 321 and 322. The driving synchronizer 321b and the driven synchronizer 322b are parallel and of equal length, and are respectively positioned at corresponding positions on the driving and driven rods 321 and 322. The master-slave connecting rod 323 is a long strip-shaped connecting rod with round holes at both ends, and is rotatably connected to the driving synchronizer 321b and the driven synchronizer 322b via cylindrical pins, forming a four-bar linkage with the driving rod 321, the driving synchronizer 321b, the master-slave connecting rod 323, and the driven synchronizer 322b. There are multiple crank connecting rods 324, each with round holes at both ends. One end of each crank connecting rod is rotatably connected to either the driving crank 321a or the driven crank 322a via a cylindrical pin, and the other end is rotatably connected to the blade synchronizer 325 via a cylindrical pin. Through a four-bar linkage, the rotation of the driving rod 321 is stably transmitted to the driven rod 322, ensuring synchronous rotation. The rotational motion of the driving rod crank 321a and the driven rod crank 322a is converted into the forward and backward movement of the blade synchronizing rod 325 via the crank-connecting rod 324. The aforementioned crank, synchronizing rod, crank-connecting rod 324, driving-driven connecting rod 323, and blade synchronizing rod 325 are arranged in a set at both ends of the blade 200, forming a crank-slider mechanism. For the left and right blade groups, the left and right parts of the driving rod 321 respectively drive the corresponding multiple blades 200 to move synchronously via corresponding transmission linkage mechanisms 320.

[0036] In other embodiments, the transmission linkage mechanism 320 can also adopt other structural forms. For example, the transmission linkage mechanism 320 can be a gear and rack mechanism, where the drive motor 310 drives the gear to rotate, the gear meshes with the rack, and the rack is connected to the blade synchronizing rod 325, thereby converting the rotational motion of the drive motor 310 into the forward and backward movement of the blade synchronizing rod 325. As another example, the transmission linkage mechanism 320 can also be a synchronous belt mechanism, where the drive motor 310 drives the driven pulley to rotate via a synchronous belt. An eccentric pin is provided on the driven pulley, and the eccentric pin is connected to the blade synchronizing rod 325 via a connecting rod, thereby converting the rotational motion of the drive motor 310 into the forward and backward movement of the blade synchronizing rod 325. As long as the transmission linkage mechanism 320 can convert the rotational motion of the drive motor 310 into the synchronous forward and backward movement of multiple blades 200, the technical solution of this application can be achieved.

[0037] In some embodiments, the grille base 400 is fixed to the back of the vehicle front grille 100 by a mounting structure. Specifically, the grille base 400 may have pre-drilled mounting holes, and a mounting post is correspondingly provided on the back of the vehicle front grille 100, with threaded holes on the mounting post; fasteners pass through the mounting holes and connect to the threaded holes, thereby fixing the grille base 400 to the back of the vehicle front grille 100. The fasteners can be screws, bolts, or rivets. Optionally, the grille base 400 may have a snap-fit, and a corresponding slot is provided on the back of the vehicle front grille 100, with the snap-fit ​​engaging with the slot; or, the grille base 400 may have a slot, and the back of the vehicle front grille 100 may have a snap-fit. Through this snap-fit ​​engagement, the grille base 400 can be assembled onto the back of the vehicle front grille 100. Further, the grille base 400 may also have a locating pin, and a locating hole is provided on the back of the vehicle front grille 100, with the locating pin engaging with the locating hole to position the grille base 400 during assembly.

[0038] In other embodiments, the grille base 400 is fixed to the back of the vehicle front grille 100 by ultrasonic welding. Specifically, welding ribs are provided on the grille base 400, and the welding ribs abut against the back of the vehicle front grille 100. During ultrasonic welding, the welding ribs melt and bond with the back of the vehicle front grille 100, thereby fixing the grille base 400 to the back of the vehicle front grille 100. The welding ribs can be spaced apart circumferentially along the grille base 400, or they can be provided at the mounting ears of the grille base 400.

[0039] Through the aforementioned mounting structure or ultrasonic welding method, the grille base 400 can be stably fixed to the back of the vehicle's front grille 100, providing a reliable mounting base for the blades 200 and the drive mechanism 300.

[0040] Based on the above structure, the complete working process of the embodiments of this application is described below.

[0041] In the initial state, the front grille assembly is in the closed position. The sealing block 210 on the blade 200 is embedded in the sealing hole 111 of the vehicle's front grille 100. The flat portion of the blade 200 is compressed and fitted with the elastic seal 120 disposed around the sealing hole 111, thus sealing the sealing hole 111 and preventing airflow from passing through it. At this time, the vent 112 located in the middle area of ​​the vehicle's front grille 100 remains open, allowing air to flow through it. In this sealing method, the sealing block 210 is directly embedded in the sealing hole 111, placing the sealing position at the grille opening 110. The blade 200 can be closer to the outer surface of the vehicle's front grille 100, which helps reduce wind resistance. At the same time, the compressed fit between the blade 200 and the elastic seal 120 reduces air leakage in the closed state and helps maintain the visual continuity of the vehicle's front grille 100.

[0042] When the front grille assembly needs to be opened, the drive motor 310 starts. In response to the rotation of the drive motor 310, the drive motor 310 drives the drive rod 321 to rotate. The drive rod 321, through the drive rod synchronizing rod 321b, the master-slave connecting rod 323, and the driven rod synchronizing rod 322b, drives the driven rod 322 to rotate synchronously. For ease of understanding, Figure 9 The diagram schematically illustrates the motion paths G1 of the end of the synchronizing rod during rotation of the driving rod 321 and the driven rod 322, the forward and backward movement path G2 of the blade synchronizing rod 325, and the movement path G3 of the blade sliding rod 220 in the slide rail 410.

[0043] As the driving rod 321 and driven rod 322 rotate, the driving rod crank 321a and driven rod crank 322a rotate accordingly. The crank-connecting rod 324 moves under the influence of the driving rod crank 321a and driven rod crank 322a, causing the blade synchronizing rod 325 to move back and forth. The blade synchronizing rod 325 then drives multiple blade traction rods 230, which are rotatably connected to it, to move synchronously back and forth.

[0044] Driven by the blade traction rod 230, the blade 200 moves backward as a whole. At this time, the blade sliding rod 220 moves along the translation section 411 of the slide rail 410. As the blade 200 continues to move backward, the sealing block 210 exits from the sealing hole 111 of the vehicle front grille 100. The planar portion of the blade 200 separates from the elastic seal 120.

[0045] When the blade slide rod 220 enters the rotating section 412 of the slide rail 410, the rotating section 412 of the slide rail 410 changes the direction of movement of the blade slide rod 220. Because the direction of movement of the blade slide rod 220 changes, while the blade traction rod 230 continues to move driven by the drive mechanism 300, the blade 200 rotates around the blade traction rod 230. As the blade 200 rotates, both the blade 200 and the sealing block 210 avoid the grille opening 110, and the sealing hole 111 is opened, allowing air to flow through. At this time, the front grille assembly reaches a stable open position. Multiple blades 200 in the left and right blade groups move synchronously, causing the sealing holes 111 on both sides to open synchronously.

[0046] When the front grille assembly needs to be closed, the drive motor 310 rotates in the reverse direction. In response to the reverse rotation of the drive motor 310, the drive rod 321 rotates in the reverse direction, which drives the driven rod 322 to rotate synchronously in the reverse direction via the master-slave connecting rod 323. The crank connecting rod 324 drives the blade synchronizing rod 325 to move in the reverse direction, and the blade synchronizing rod 325 drives the blade traction rod 230 to move in the reverse direction.

[0047] The blade 200 first rotates in the opposite direction, and the blade sliding rod 220 returns from the rotating section 412 of the slide rail 410 to the translation section 411. As the blade traction rod 230 continues to move forward, the blade 200 moves forward as a whole, and the sealing block 210 approaches the sealing hole 111 of the vehicle's front grille 100. When the sealing block 210 is inserted into the sealing hole 111, the planar portion of the blade 200 contacts and compresses the elastic seal 120, forming a seal. At this time, the front grille assembly returns to the closed position, the sealing hole 111 is resealed, and the vent 112 remains open. This completes one working cycle.
