[0024] 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.

[0025] Embodiment 1

[0026] like Figure 1 — Figure 5 As shown, the utility model provides an external active air intake grille including a rear frame 100 , an execution shaft 110 , blades 200 , a connecting member 300 , an actuator 120 and a chip 121 .

[0027] An actuator shaft 110 is installed in the rear frame 100; the blade 200 is hinged on the rear frame 100, and the actuator shaft 110 and the blade 200 are connected by at least two connecting members 300. At least two actuators 120 are installed in the rear frame 100, and each actuator 120 is connected to the actuator shaft 110. Multiple actuators 120 are controlled by the same chip 121. When working, the chip 121 controls each actuator 120 to operate simultaneously, so that the multiple actuators 120 can drive the actuator shaft 110 to rotate synchronously, so that the actuator shaft 110 drives each connecting member 300 to move, so that the blade can be driven The blade 200 moves, thereby realizing the opening or closing of the blade 200. Furthermore, multiple actuators 120 provide torque to the blade 200 at the same time to increase the power of the blade 200 during the movement, so that people can choose a blade 200 with a heavier weight or when the blade 200 is subjected to a larger wind resistance, the external active air intake grille can also be smoothly opened or closed; secondly, when assembling the external active air intake grille, people can also choose an actuator 120 with a smaller specification or a smaller torque, thereby reducing the space occupied by the actuator 120, so that the rear frame 100 with a smaller internal space can also be installed with the actuator 120.

[0028] Furthermore, the car's onboard computer is electrically connected to the chip. When in use, people can control the chip through the onboard computer so that the chip can control the operation of the actuator.

[0029] The rear frame 100 is provided with mounting frames 130 having the same number as the actuators 120. Each mounting frame 130 is provided with a cavity 131 for accommodating the corresponding actuator 120. The actuator 120 passes through the mounting frame 130. During installation, people need to insert each actuator 120 into the corresponding cavity 131 and pass the actuator shaft 110 through the actuator 120 so that the actuator 120 can drive the actuator shaft 110 to rotate.

[0030] There is one actuator shaft 110 , and each connecting member 300 is connected to the actuator shaft 110 .

[0031] Each of the connecting members 300 includes a mounting frame 310 connected to the blade 200, an active rod 320 connected to the execution shaft 110 is hinged on one side of each mounting frame 310, and a driven rod 330 hinged to the rear frame 100 is hinged on the other side of each mounting frame 310. Specifically, the execution shaft 110 passes through the active rod 320, and the outer surface of the active rod 320 is engaged with the active rod 320. A main mounting column 311 hinged to the active rod 320 is provided on one side of the mounting frame 310, and a secondary mounting column 312 hinged to the driven rod 330 is provided on the other side of the mounting frame 310. The rear frame 100 is provided with a mounting column 311 for inserting the active rod 320. The rear frame 100 further comprises a first slot 140 for inserting one end of the driven rod 330, and the execution shaft 110 extends into the first slot 140. The inner wall of the second slot 150 is hinged to the driven rod 330. When the execution shaft 110 drives the active rod 320 to rotate, one end of the active rod 320 is hinged to the corresponding mounting frame 310 through the main mounting column 311, and one end of the driven rod 330 is hinged to the corresponding mounting frame 310 through the auxiliary mounting column 312. The other end of the driven rod 330 is hinged to the inner wall of the corresponding second slot 150. In this way, the active rod 320 can drive the mounting frame 310 and the driven rod 330 to move.

[0032] A plurality of anti-error plates 160 are provided in the rear frame 100 , and the execution shaft 110 moves through each anti-error plate 160 . The provision of the plurality of anti-error plates 160 can ensure that a part of the execution shaft 110 will not shake in the rear frame 100 .

[0033] A front frame 400 is provided on one side surface of the rear frame 100, and the blade 200 is located between the front frame 400 and the rear frame 100. An air inlet 410 is opened on the front frame 400, and an air vent 170 is provided in the rear frame 100. When the blade 200 is opened, the air inlet 410 is connected with the air vent 170, so that the interior of the car is connected with the outside through the air inlet 410 and the air vent 170. When the blade 200 is closed, the air vent 170 is not connected with the air inlet 410, and the interior of the car is not connected with the outside.

[0034] Embodiment 2

[0035] like Figure 6 As shown, the difference between this embodiment and the first embodiment is that the actuator shaft 110 is configured as a multi-stage type in this embodiment.

[0036] Specifically, the number of the actuator shafts 110 is the same as the number of the actuators 120, and the actuators 120 are connected to adjacent actuator shafts 110. When working, each actuator 120 drives the actuator shaft 110 connected to it to rotate. Since a connecting member 300 is connected between each actuator shaft 110 and the blade 200, the actuator shaft 110 can drive the same blade 200 to move through its corresponding connecting member 300, thereby providing a larger torque for the blade 200.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
