[0001] The utility model belongs to the technical field of automobiles and relates to an external active air intake grille. Background Art

[0002] The main function of the active grille is heat management and reducing wind resistance:

[0003] 1. Heat management: When air intake is not needed, the blades are closed to quickly increase the temperature inside the car; when air intake is needed, the blades are opened at a certain angle to control the amount of air intake to dissipate heat to different degrees on the heating components inside the car, thereby achieving heat management and reducing the energy consumption of the car;

[0004] 2. Reduce wind resistance: When heat dissipation is not needed, the active air intake grille can be completely closed, which can reduce the resistance encountered by the car during driving.

[0005] In the existing market, when the blades are closed for car washing or encountering strong wind impact, the blades are impacted by the water flow or wind and may be forced to open. In other words, the blades are washed away by water or wind, causing the actuator used to drive the blades to open or close to be subjected to a large torque, resulting in damage to the actuator.

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] like Figure 1 — Figure 2 and Figure 4 As shown, the utility model provides an external active air intake grille including a frame 100 , blades 200 , a driving member 300 , a connecting rod assembly 400 and a self-locking member 500 .

[0031] In the present invention, when the blade 200 blocks the ventilation opening of the housing 600, the blade 200 is in a closed state; when the blade 200 no longer blocks the ventilation opening, the blade 200 is in an open state.

[0032] The blade 200 is arranged in the frame 100, and the blade 200 can be turned over in the frame 100; the driving member 300 is arranged in the frame 100, and the driving member 300 is connected to the blade 200 through the connecting rod assembly 400, and a self-locking member 500 is provided in the frame 100 or on the connecting rod assembly 400 to make the connecting rod assembly 400 self-locking. The external active air intake grille also includes a shell 600, wherein the frame 100 is fixedly installed on the shell 600, and an air vent 610 corresponding to the blade 200 is opened on the shell 600. When the active air intake grille is in a closed state, the blade 200 blocks the air vent 610, and the self-locking member 500 makes the connecting rod assembly 400 in a self-locking state. When the blade 200 is subjected to oncoming wind or water, the blade 200 has a tendency to turn over to the inside of the frame 100, and in this process In the process, the blade 200 will transfer the force it receives to the connecting rod assembly 400, and the self-locking member 500 has locked the connecting rod assembly 400 at this time. In this way, the force received by the connecting rod assembly 400 will be transferred to the self-locking member 500 to prevent the connecting rod assembly 400 from moving in the frame 100 at this time, that is, to prevent the torque generated on the connecting rod assembly 400 from being transmitted to the driving member 300, thereby protecting the driving member 300; when the active air intake grille is to be opened, the driving member 300 drives the connecting rod assembly 400 to move. During this process, the blade 200 will first rotate in the direction a3 by a certain angle until the connecting rod assembly 400 is in a straight line. This process is called unlocking action. Thereafter, the blade 200 will rotate in the opposite direction of the direction a3 until the blade 200 is in the open state, and the driving member 300 stops working.

[0033] The connecting rod assembly 400 includes a first connecting rod 410 and a second connecting rod 420, one end of the first connecting rod 410 is hinged to one end of the second connecting rod 420, the other end of the second connecting rod 420 is hinged to the blade 200, and the other end of the first connecting rod 410 is hinged to the driving member 300. When the blade 200 is in a closed state, there is a self-locking angle e between the first connecting rod 410 and the second connecting rod 420, and the degree of the self-locking angle e is between 90° and 180°. Both sides of the frame 100 are provided with wing plates 110, and the blade 20 0 is provided with side panels 210 on both sides, and a first hinge rod 211 movably connected to the corresponding wing panel 110 is provided at one end of the side panel 210, and a second hinge rod 212 movably connected to the second connecting rod 420 is provided in the middle of the side panel 210. The driving member 300 includes a driving rod 310 movably arranged between the two wing panels 110, and the driving rod 310 is fixedly connected to one end of the first connecting rod 410 away from the second connecting rod 420, and an actuator 320 for driving the driving rod 310 to rotate is provided on one of the wing panels 110.

[0034] In the present invention, the outer angle (not marked in the figure) is the angle of the connection between the first connecting rod 410 and the second connecting rod 420 toward the side of the shell 600, and the inner angle (not marked in the figure) is the angle of the connection between the first connecting rod 410 and the second connecting rod 420 away from the side of the shell 600, wherein the inner angle is complementary to the outer angle, and when the degree of the outer angle is less than 180 and greater than 90°, the outer angle is transformed into a self-locking angle e.

[0035] When the external active air intake grille is in the state where the blades 200 are closed, an outer angle is formed between the first link 410 and the second link 420. When the blades 200 are subjected to the force of wind or water from the outside, the wind force will force the blades 200 to generate a force in the direction of a4, which will be transmitted to the link assembly 400 and then to the self-locking member 500 through the link assembly 400. At this time, the first link 410 or the second link 420 is restricted by the self-locking member 500, so that the first link 410 and the second link 420 can be avoided. The self-locking angle e between the two becomes smaller, that is, the first link 410 is prevented from rotating, thereby preventing the first link 410 from applying a torque to the drive rod 310, thereby protecting the actuator 320; when the external active air intake grille is in the state where the blade 200 changes from a closed state to an open state, the actuator 320 will drive the drive rod 310 to rotate in the direction a1. Since the first link 410 is fixedly connected to the drive rod 310, the second link 420 is hinged to the first link 410, and the second link 420 and the side plate 210 of the blade 200 are connected by the second hinge. 212 is hinged, and the side plate 210 of the blade 200 is hinged to the frame 100 through the first hinge rod 211, so that the blade 200 at this time rotates a certain angle in the direction a3 with the first hinge rod 211 as the center. At this time, the degree of the self-locking angle e between the first link 410 and the second link 420 will gradually increase until the first link 410 and the second link 420 are in a straight line and the self-locking angle e is 180°. At this time, the self-locking angle e will not exist, and the self-locking angle e will automatically turn into an external angle. Thereafter, the degree of the self-locking angle e between the first link 410 and the second link 420 will increase. The connection between the two will move in an arc shape away from the shell 600, and the inner angle will gradually become smaller, while the outer angle will gradually increase. In this way, the distance between the end of the second connecting rod 420 away from the first connecting rod 410 and the driving rod 310 will gradually decrease, that is, the connecting rod assembly 400 can drive the blade 200 to flip in the direction away from the shell 600 with the first hinge 211 as the center, and when the first connecting rod 410 rotates to a predetermined angle around the driving rod 310, the actuator 320 stops working, and the blade 200 is in an open state.

[0036] Embodiment 1

[0037] like Figure 3 As shown, this embodiment is the first structure of the self-locking member 500.

[0038] The self-locking member 500 includes a first locking block 510 disposed on the wing plate 110. When the blade 200 is in a closed state, the first locking block 510 abuts against the bottom edge of the second connecting rod 420. In this way, when the blade 200 is subjected to the force of external wind or water, the blade 200 will rotate in the direction of a4, so that the blade 200 transmits the force to the second connecting rod 420, thereby prompting the second connecting rod 420 to rotate in the direction of the first locking block 510, and the first locking block 510 will limit the second connecting rod 420 from rotating in the direction of the first locking block 510. The frame 100 is rotated downward, that is, the second connecting rod 420 will transmit the force to the first locking block 510, and the first locking block 510 will transmit the force to the frame 100. In this way, the second connecting rod 420 can be prevented from transmitting the force to the first connecting rod 410, thereby preventing the first connecting rod 410 from applying a torque to the driving rod 310, and further preventing the actuator 320 from being subjected to torque when the active air intake grille is in the blade 200 closed state, thereby protecting the actuator 320.

[0039] Embodiment 2

[0040] like Figure 5 As shown, this embodiment is the second structure of the self-locking member 500.

[0041] The self-locking member 500 includes a second locking block 520 disposed on the wing plate 110. When the blade 200 is in a closed state, the second locking block 520 abuts against the bottom edge of the first connecting rod 410. In this way, when the blade 200 is subjected to the force of external wind or water, the blade 200 will rotate in the direction a4, so that the blade 200 transmits the force to the second connecting rod 420. Since the first connecting rod 410 and the second connecting rod 420 are hinged, the force on the second connecting rod 420 is transmitted to the first connecting rod 410, thereby causing the first connecting rod 410 to rotate. The connecting rod 410 rotates toward the second locking block 520, and the second locking block 520 will limit the downward rotation of the first connecting rod 410 relative to the frame 100, that is, the first connecting rod 410 will transfer the force to the second locking block 520, and the second locking block 520 will transfer the force to the frame 100. In this way, the first connecting rod 410 can be prevented from applying torque to the driving rod 310, thereby preventing the actuator 320 from being subjected to torque when the active air intake grille is in the blade 200 closed state, thereby protecting the actuator 320.

[0042] Embodiment 3

[0043] like Figure 6 As shown, this embodiment is the third structure of the self-locking member 500.

[0044] The self-locking member 500 includes a first locking plate 530 disposed on the second connecting rod 420. The first locking plate 530 is located at the top surface of the second connecting rod 420 close to one end of the first connecting rod 410. When the blade 200 is in a closed state, the first locking plate 530 abuts against the top edge of the first connecting rod 410. In this way, when the blade 200 is subjected to the force of external wind or water, the blade 200 will rotate in the direction of a4, so that the blade 200 transmits the force to the second connecting rod 420, thereby causing the second connecting rod 420 to move downward, and the first locking plate 530 The plate 530 presses against the top edge of the first link 410, and the first lock plate 530 will limit the second link 420 from rotating downward relative to the frame 100, that is, the second link 420 will transmit the force to the first lock plate 530, so that the second link 420 can be prevented from transmitting the force to the first link 410, thereby preventing the first link 410 from applying torque to the drive rod 310, and further preventing the actuator 320 from being subjected to torque when the active air intake grille is in the blade 200 closed state, thereby protecting the actuator 320.

[0045] Embodiment 4

[0046] like Figure 7 As shown, this embodiment is the fourth structure of the self-locking member 500.

[0047] The self-locking member 500 includes a second locking plate 540 disposed on the first connecting rod 410, and the second locking plate 540 is located at the top surface of the first connecting rod 410 close to one end of the second connecting rod 420. When the blade 200 is in a closed state, the second locking plate 540 abuts against the top edge of the second connecting rod 420. In this way, when the blade 200 is subjected to the force of external wind or water, the blade 200 will rotate in the direction a4, so that the blade 200 transmits the force to the second connecting rod 420. Since the first connecting rod 410 and the second connecting rod 420 are hinged, the second connecting rod 420 The force is transmitted to the first connecting rod 410, thereby prompting the first connecting rod 410 to rotate downward. At this time, the second locking plate 540 presses against the top edge of the second connecting rod 420, and the second locking plate 540 will limit the downward rotation of the first connecting rod 410 relative to the frame 100, that is, the first connecting rod 410 will transmit the force to the second locking plate 540, so that the first connecting rod 410 can be prevented from applying torque to the driving rod 310, thereby preventing the actuator 320 from being subjected to torque when the active air intake grille is in the closed state of the blades 200, thereby protecting the actuator 320.
