In the present invention, when the blade 4 is in the closed state, the arc-shaped end surfaces of the first abutment plate 5, the second abutment plate 6 and the third abutment plate 7 fit with the semicircular part of the blade 4. When the vehicle needs to dissipate heat, the driving mechanism can drive the round rod 3 to rotate, and the driving mechanism is actuated to make the connecting rod 8 slide to the left in the slide groove 202 so that the first abutment plate 5, the second abutment plate 6 and the third abutment plate 7 move to the left away from the blade 4, and the blade 4 is opened and in a horizontal state. In cold weather, when the engine preheating time is reduced, the driving mechanism can drive the round rod 3 to rotate in the opposite direction, and the driving mechanism is actuated to make the connecting rod 8 slide to the right in the slide groove 202 so that the first abutment plate 5, the second abutment plate 6 and the third abutment plate Plate 7 moves to the right and fits with blade 4, so that blade 4 is closed. When blade 4 is opening or closing, blade 4 will abut against second abutment plate 6. Second abutment plate 6 is acted upon by force to rotate relative to third abutment plate 7 and squeeze the buffer device. When blade 4 is in a vertical state or a horizontal state, the buffer device returns second abutment plate 6 to its original position. When the vehicle speed is higher, blade 4 needs to be closed. Ends of first abutment plate 5, second abutment plate 6 and third abutment plate 7 fit tightly with ends of blade 4, so that blade 4 is not easily deformed when affected by wind, and no gap will appear between two blades 4 or between blade 4 and the wall of outer frame 10, so as to prevent wind from entering the interior of the car through the grille.

[0024] As a preferred embodiment of the present invention, it may also have the following additional technical features:

[0025] In this embodiment, the driving device includes an electric driving device 9, a screw rod 11, and a plurality of movable plates 12, a rack plate 13, a first gear 14, a rotating rod 15, and a second gear 16. The electric driving device 9 is arranged in the cavity 201 to drive the screw rod 11 to rotate. A plurality of movable plates 12 are arranged at intervals on the screw rod 11, and one end of the movable plate 12 is slidably connected to the skeleton 2. A rack plate 13 is arranged on one side of the movable plate 12. The rotating rod 15 is rotatably arranged on the wall in the cavity 201. The rotating rod 15 is provided with the first gear 14 meshing with the rack plate 13, and the round rod 3 is provided with the second gear 16 meshing with the first gear 14. When the electric drive device 9 is working, it drives the screw rod 11 to rotate, and the moving plate 12 moves downward to make the first gear 14 rotate counterclockwise, driving the second gear 16 to rotate clockwise, thereby making the blade 4 rotate open. When the electric drive device 9 is working, it drives the screw rod 11 to rotate in the opposite direction, and the moving plate 12 moves upward to make the first gear 14 rotate clockwise, driving the second gear 16 to rotate counterclockwise, thereby making the blade 4 rotate closed. Specifically, the electric drive device 9 is a motor; a long groove is provided on the wall of the frame 2, and one end of the moving plate 12 can slide in the long groove.

[0026] In this embodiment, the diameter of the first gear 14 is larger than that of the second gear 16. The second gear 16 is a small gear, which rotates faster, so that the blades 4 can be opened or closed faster, and the distance that the moving plate 12 moves upward or downward can be reduced.

[0027] In this embodiment, the length and thickness of the first abutment plate 5 and the third abutment plate 7 are greater than the length and width of the slide groove 202. The slide groove 202 makes the cavity 201 on the frame 2 relatively sealed to prevent dust from entering the cavity 201 and causing the subsequent rack plate 13, the first gear 14 and the second gear 16 to cooperate unsmoothly.

[0028] In this embodiment, the frame 2 is provided with a placement groove 203, which is in communication with the cavity 201 and the slide groove 202; the driving mechanism includes a plurality of inclined plates 17 and first springs 18, the inclined plates 17 being arranged on the driving device, and the first springs 18 being arranged in the placement grooves 203 and abutting against one side of the connecting rod 8. The original state of the first spring 18 is in a compression state, when the moving plate 12 moves downward, the inclined plate 17 moves downward, and the first spring 18 reacts to the connecting rod 8 to make it move leftward, thereby driving the first abutting plate 5, the second abutting plate 6 and the third abutting plate 7 to move leftward away from the blade 4, when the moving plate 12 moves upward, the inclined plate 17 moves upward, and the connecting rod 8 moves rightward under the action of the inclined plate 17 and compresses the first spring 18, so that the first abutting plate 5, the second abutting plate 6 and the third abutting plate 7 move rightward and fit closely with the blade 4.

[0029] In this embodiment, the driving mechanism further includes a plurality of blocking rods 19, which are respectively arranged on one side of the connecting rod 8 and one side of the wall of the placement slot 203 and are sleeved in the first spring 18 to prevent the first spring 18 from falling out of the placement slot 203.

[0030] In this embodiment, the second abutment plate 6 is provided with a plurality of swing rods 601, and the third abutment plate 7 is provided with a plurality of swing slots 701, and the swing rods 601 are rotatably connected to the wall of the swing slot 701; the buffer device includes a plurality of second springs 20, and the second springs 20 are arranged between the second abutment plate 6 and the third abutment plate 7. The diameter of the first gear 14 is larger than that of the second gear 16, and the round rod 3 rotates faster, thereby causing the blade 4 to rotate faster. During the process of opening or closing the blade 4, the blade 4 will interfere with the end of the second abutment plate 6. When the blade 4 is opened, the second abutment plate 6 will rotate counterclockwise and squeeze the second spring 20 on the left. After the blade 4 is opened, the second spring 20 on the left exerts a force on the second abutment plate 6 to return it to its original position. When the blade 4 is closed, the second abutment plate 6 will rotate clockwise and squeeze the second spring 20 on the right due to the force of the blade 4. After the blade 4 is closed, the second spring 20 on the right exerts a force on the second abutment plate 6 to return it to its original position. Specifically, round rods are provided on both sides of the swing rod 601, and the round rods are rotatably connected to the wall of the swing groove 701; a plurality of grooves 702 are provided on the third abutment plate 7, one end of the second spring 20 is fixed in the groove 702, and the other end abuts against the bottom of the second abutment plate 6.

[0031] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.
