[0016] Beneficial technical effects of the utility model:

[0017] The utility model provides a double air door outlet structure with a single pulley structure, wherein gears 4A, 4B, 5A and 5B are coaxial secondary gears, and the gears are incomplete tooth structures, and the transmission is irreversible, the driving wheels are gears 4A and 4B, and the driven wheels are gears 58 and 5B, the gears 4A drive the gears 5A to rotate, and the gears 4B drive the gears 5B to rotate, the gears 5A and 5B are connected to the door panels and the door panels, and a sealing block is attached to one side of the door panel;

[0018] The motor provides power, and a rotor is connected to the motor for rotation. A gear 1 is meshed on the rotor, and a gear 2 is meshed at the bottom of the gear 1, and a gear 3 is meshed at one side of the bottom of the gear 2, and a gear 4B is meshed at one side of the gear 3. The inner side of the gear 4B meshes with the gear 5B, and the gear 5A and the gear 4B are meshed and connected for rotation. The output torque of the motor is amplified through the gear transmission deceleration, and the gears 5A and 5B are driven to rotate intermittently through the gears 4A and 4B. In the process of rotation, the door panel and the door panel 2 are driven to close. When the door panel and the door panel 2 are completely closed, the gears The locking arc of wheel 4A is incompletely meshed with gear 5A to enter a locked state. At this time, the sealing block in contact with the door frame air outlet is compressed to ensure that the door panel is closed and sealed to prevent cold leakage.

When aligned, they are opened and closed at the same time. When aligned horizontally, one of the door panel and the second door panel is opened and the other is closed. When the gear continues to rotate and meshes with the gear of one of the door panel and the second door panel, the other closed door panel and the second door panel slowly unfolds, realizing the adjustable opening and closing function.

[0019] When the external force rotates the door panel and the second door panel, and the torque is greater than the damping torque of the friction plate, the friction plate is lifted up, and the shaft and the gear rotate relatively, thereby protecting the shaft from distortion and deformation and gear misalignment when external force acts;

[0020] The gears rotate under the driving force of the motor. When the door panel and the second door panel are fully opened or fully closed, the rotation of the door panel and the second door panel is hindered, and the door panel and the second door panel remain in a static position. When the motor continues to drive, sliding occurs between the gears and the rotating shaft, and the friction plate enters the groove of the rotating shaft, which can ensure the accurate relative position of the rotating shaft and the gear, and avoid the position deviation of the rotating shaft and the gear during resetting, which will cause the door panel and the second door panel to be not sealed when closed.

[0036] A linkage gear set is meshed on the gear 4A6 and the gear 4B7, a speed reduction connection set is installed on the gear 5A8, and a sealing set is provided on the outer side cover of the door panel 10.

[0037] The linkage gear set includes a rotor 2, a gear one 3, a gear two 4 and a gear three 5;

[0038] The motor 1 is rotatably connected with a rotor 2, the rotor 2 is meshed with a gear 1 3, the bottom of the gear 1 3 is meshed with a gear 2 4, the bottom side of the gear 2 4 is meshed with a gear 3 5, one side of the gear 3 5 is meshed with a gear 4B7, the inner side of the gear 4B7 is meshed with a gear 5B9, and the gear 5A8 is meshed and rotatably connected with the gear 4B7.

[0039] The reduction connection group includes a friction plate 13 and a rotating shaft 14 . The rotating shaft 14 is built into the gear 5A8 . The friction plate 13 is installed in the gear 5A8 on one side of the rotating shaft 14 .

[0040] The sealing group includes a door frame 11 and a sealing block 12 . The door frame 11 is provided on the outer side of the door panel 10 , and the sealing block 12 is installed on one side of the door panel 10 inside the door frame 11 .

[0041] The gear 5A8 and the gear 5B9 are of a split structure or an integrated structure. The gear 5A8 and the gear 5B9 are of a structure that penetrates the linkage housing body 15 and is spliced ​​and connected with the door panel 10 and the door panel 2 16 .

[0042] The lower end of the shaft 14 is inserted into the middle of the gear 5A8 and the gear 5B9 for engagement, and the friction plate 13 is inserted into the gear 5A8 and contacts the outer side of the shaft 14. The shaft 14 is supported by two groups, one in a straight line structure and the other in a cross structure.

[0043] like Figure 1 - Fig.11 As shown, the working process of the double air door outlet structure with a single puller structure provided in this embodiment is as follows:

[0044] Gear 4A6, gear 4B7, gear 5A8 and gear 5B9 are coaxial secondary gears, and the gears are incomplete tooth structures, and the transmission is irreversible. The driving wheels are gear 4A6 and gear 4B7, and the driven wheels are gear 5A8 and gear 5B9. Gear 4A6 drives gear 5A8 to rotate, and gear 4B7 drives gear 5B9 to rotate;

[0045] Gear 5A8 and gear 5B9 are connected to door panel 10, and a sealing block is attached to one side of door panel 10;

[0046] The motor 1 provides power, and the motor 1 is rotatably connected with the rotor 2, and the rotor 2 is meshed with the gear 1 3, and the gear 2 4 is meshed with the bottom of the gear 1 3, and the gear 3 5 is meshed with the side of the bottom of the gear 2 4, and the gear 4B7 is meshed with the gear 5B9 on one side of the gear 3 5. The gear 5A8 and the gear 4B7 are staggered and meshed and connected to rotate, and the motor output torque is amplified through the gear transmission deceleration, and the gear 5A8 and the gear 5B9 are intermittently driven to rotate through the gear 4A6 and the gear 4B7, and the door panel 10 and the door panel 2 16 are driven to close during the rotation. When the door panel 10 and the door panel 2 16 are completely closed, The locking arc of gear 4A6 is meshed with the incomplete teeth of gear 5A8 to enter a locked state. At this time, the sealing block 12 in contact with the air outlet of door frame 11 is compressed to ensure that door panel 10 is closed and sealed to prevent cold leakage. The opening and closing time of door panel 10 and door panel 2 16 are controlled by adjusting the tooth directions of gear 5A8 and gear 5B9. When aligned, they are opened and closed at the same time. When aligned horizontally, one of door panel 10 and door panel 2 16 is opened and the other is closed. When the gear continuously rotates and meshes with the gear of one of door panel 10 and door panel 2 16, the other of door panel 10 and door panel 2 16 is slowly opened, realizing the adjustable opening and closing function.

[0047] like Fig.10 As shown, when the external force rotates the door panel 10 and the second door panel 16, when the torque is greater than the damping torque of the friction plate 13, the friction plate 13 is lifted up, and the shaft and the gear rotate relatively, thereby protecting the shaft from distortion and deformation and gear misalignment when the external force acts;

[0048] like Fig.11 As shown, the gear rotates under the driving force of the motor. When the door panel 10 and the door panel 16 are fully opened or fully closed, the rotation of the door panel 10 and the door panel 16 is blocked, and the door panel 10 and the door panel 16 remain in a static position. When the motor continues to drive, sliding occurs between the gear and the shaft, and the friction plate 13 enters the groove of the shaft, which can ensure the accurate relative position of the shaft and the gear, avoid the position deviation of the shaft and the gear during resetting, and cause the door panel 10 and the door panel 16 to be not sealed when closed.
