A plurality of partition plates 141 are fixedly connected to the circumferential side wall of the mounting seat 14 at intervals. The adjacent partition plates 141 define a range of rotation of the shielding mechanism 2. The air blown out from the air outlet 11 is blown out from the space between the adjacent partition plates 141.

In the present embodiment, the driving mechanism 3 includes a driver 31 detachably provided in the mount 14, a turntable 32 connected to the driver 31, and a controller provided in the hood 1. The driver 31 of the present embodiment adopts a stepping motor 311, and the turntable 32 is coaxially connected to the stepping motor 311.

The shielding mechanism 2 is provided on the turntable 32. The turntable 32 rotates the shielding mechanism 2. The controller is used for receiving a parking air conditioner start-stop signal to control the stepper motor 311 to start. The parking air conditioner is started, and the controller controls the stepping motor 311 to start and drive the turntable 32 to rotate. The rotary disk 32 drives the shielding mechanism 2 to open the air outlet 11. The parking air conditioner stops, and the controller controls the stepping motor 311 to drive the turntable 32 to reversely rotate.

Wherein, be provided with the sensor on the baffle 141, promptly shelter from the mechanism 2 and expand the back entirely, shelter from mechanism 2 and can with one of them baffle 141 butt, this baffle 141 is sensor-induced the back and is transmitted the signal to the controller, and the controller stops driving. After all the shielding mechanism 2 is folded, the shielding mechanism 2 is abutted against the other partition board 141, the sensor on the other partition board 141 senses and transmits signals to the controller, the controller stops driving, signals of the sensor are received in the process that the controller is started or stopped by the parking air conditioner, and the controller can control the stepping motor 311 to drive the shielding mechanism 2 to rotate in place.

For example, referring to fig. 1 and 3, a mounting groove 142 is formed in the mounting seat 14 for mounting the stepper motor 311. Fixed supports 143 positioned on two sides of the stepping motor 311 are fixedly connected in the mounting groove 142. The fixed support 143 abuts against both sides of the stepper motor 311 and limits the stepper motor 311 from rotating in the mounting groove 142. Mounting holes 312 are formed in the two sides, close to the fixed support 143, of the stepping motor 311. The mounting holes 312 are screwed with bolts or screws and then tightened into the mounting base 14 to fix the stepper motor 311 in the mounting groove 142.

Further, the output shaft of the stepping motor 311 is directed vertically upward. The key slot matched with the output shaft of the stepping motor 311 is arranged at the axis of the turntable 32, and the output shaft of the stepping motor 311 is inserted into the key slot to realize coaxial connection so that the stepping motor 311 drives the turntable 32 to rotate.

It is noted that the turntable 32 has a plurality of through holes, and the turntable 32 is positioned on the mounting base 14 to be matched with the mounting groove 142, so that the turntable 32 can rotate in the mounting groove 142.

In the present embodiment, referring to fig. 4 and 5, the shielding mechanism 2 has a first state and a second state, when the shielding mechanism 2 is in the first state, the air outlet 11 is opened, when the shielding mechanism 2 is in the second state, the air outlet 11 is closed, and the stepper motor 311 is used for driving the shielding mechanism 2 to switch between the first state and the second state.

Further, the shielding mechanism 2 comprises several pendulum blade sets. Each swing blade group has a folding state and an unfolding state, wherein the folding state is a first state, and the unfolding state is a second state. When the swing blade groups are in the folding state, the air outlet 11 is completely opened, and when the swing blade groups are in the unfolding state, the air outlet 11 is closed. The stepper motor 311 is used to drive each swing blade set to switch between a folded state and an unfolded state.

The plurality of swing blade groups are rotatably arranged on the rotary table 32, and the swing blade groups rotate along the circumferential direction of the rotary table 32, so that the plurality of swing blade groups all rotate along the circumferential direction of the air outlet 11, so that the plurality of swing blades rotate in the air outlet 11 along with the rotary table 32, and the air outlet 11 is opened or closed.

Specifically, each swing blade group includes a driving swing blade 21 and a plurality of driven swing blades 22. The stepper motor 311 is used for driving the driving swing blade 21 in each swing blade group to drive the driven swing blades 22 to rotate. Connectors are arranged between the driving swing blade 21 and the driven swing blade 22 and between the driven swing blade 22 and the driven swing blade 22 in each swing blade group. The driving swing blade 21 drives a plurality of driven swing blades 22 to fold or unfold through the connecting piece.

In other embodiments, the connector is omitted. The driving swing blade 21 and the driven swing blade 22 in each swing blade group may be rotatably connected to the turntable 32, that is, the axes of the driving swing blade 21 and the driven swing blade 22 are perpendicular to the axis of the turntable 32, and the driving swing blade 21 and the driven swing blade 22 turn over to open or close the air outlet 11.

Specifically, when the swing blade group is in the first state, the planes of the driving swing blade 21 and the driven swing blade 22 are axially parallel to the air outlet 11 so as to open the air outlet 11; when the swing blade set is in the second state, the planes of the driving swing blade 21 and the driven swing blade 22 are perpendicular to the circumferential direction of the air outlet 11, so as to close the air outlet 11.

Further, the driving swing blade 21 and the driven swing blade 22 are rotatably connected to the end of the turntable 32 and the output shaft of the stepping motor 311 through gear matching to realize driving, so that the driving swing blade 21 and the driven swing blade 22 in each swing blade group are mutually close after rotating respectively, and the driving swing blade 21 and the driven swing blade 22 in each swing blade group in the circumferential direction of the turntable 32 are unfolded after being turned over to cover the air outlet 11 to finish closing.

In the embodiment of the present application, the number of active swing blades 21 is four, that is, the number of partition plates 141 is also four, and the active swing blades 21 are in one-to-one correspondence with the partition plates 141. Each set of driving swing blades 21 drives a plurality of driven swing blades 22 to rotate in a range between two adjacent partition plates 141 under the connection of the connecting pieces.

Further, referring to fig. 1 and 4, a rotation shaft 321 is fixedly connected to the axle center of the turntable 32. The rotation shaft 321 is located at a side of the turntable 32 facing away from the stepper motor 311. One ends of the driving swing blade 21 and the driven swing blade 22, which are close to the turntable 32, are both rotatably connected to the rotating shaft 321, that is, the rotating shaft 321 is arranged at the ends of the driving swing blade 21 and the driven swing blade 22 in a penetrating manner. The driving swing blades 21 and the driven swing blades 22 in each swing blade group are arranged on the driving shaft 322 along the axial direction of the rotating shaft 321, so that the heights of the driving swing blades 21 and the driven swing blades 22 in each swing blade group are different.

In the above embodiment, the edge of the turntable 32 away from the rotation shaft 321 is fixedly connected with the driving shaft 322. The driving swing blade 21 is provided with a connecting groove into which the driving shaft 322 is inserted, so that the driving swing blade 21 rotates along with the rotation of the turntable 32 through the driving shaft 322 inserted into the connecting groove, and the driving swing blade 21 drives the driven swing blades 22 to rotate through the connecting piece.
