The four-duct driving mechanism 21 is used for transmitting the power of the driving mechanism to the air door, and the adjacent 4-duct air doors are all arranged on the same side of the driving mechanism.
As shown in fig. 12, the driving mechanism 20 is disposed on the left side, the first damper 8 and the second damper 9 are both disposed on the right side of the driving mechanism 20, the first damper 8 and the second damper 9 control opening or closing of the respective air ducts (first air duct and second air duct), respectively, the first damper 8 is mounted on the first damper shaft 17, the second damper 9 is mounted on the second damper shaft 16, the first damper shaft 17 is disposed above the first damper 8, and the second damper shaft 16 is disposed above the second damper 9, so that the first damper shaft 17 is disposed above the first air duct, and the second damper shaft 16 is disposed above the second air duct. Therefore, the condensed water formed on the first and second door shafts 17 and 16 does not stagnate on the first and second door shafts 17 and 16 and flows downward, thereby avoiding the failure of the first and second door shafts 17 and 16 due to freezing of the condensed water.
When the first air door 8 is in the initial closed state, the circular arc peripheral part 4-1-2 is embedded into the closing locking concave part 5-2-2-1; when the first damper 8 is closed, the circular arc outer peripheral portion 4-1-2 is fitted into the closing lock recess portion 5-2-2-1, and the circular arc outer peripheral portion 4-1-2 performs a certain degree of locking action on the closing lock recess portion 5-2-2-1 to restrict rotation of the first door shaft gear 5A, thereby restricting rotation of the first damper in the closed state.
After the first damper 8 is opened, the circular arc outer peripheral portion 4-1-2 is fitted into the opening locking recess portion 5-2-2-2. After the first air door is opened, the circular arc outer periphery is embedded into the opening locking concave part. The circular arc outer periphery performs a certain locking function on the unlocking locking concave part to limit the rotation of the first door shaft gear, so that the rotation of the first door shaft gear or the first air door in an unlocking state is limited.
When the first damper 8 is closed again, the circular arc peripheral portion 4-1-2 is fitted into the closing lock recess portion 5-2-2-1; when the first air door is closed, the circular arc outer periphery is embedded into the closing locking concave part, and the circular arc outer periphery performs a certain locking effect on the closing locking concave part to limit the rotation of the first door shaft gear, so that the rotation of the first door shaft gear or the first air door in a closed state is limited.
When the first damper 8 is in the initial closed state, the push button 4-5 abuts against the push button 4-2-2, and the push button 4-2-2 rotates in a direction away from the push button 4-5. When the second damper 9 is closed, the driven wheel lock outer peripheral portion 4-4 is fitted into the second closing lock recess portion 5-4-2-1.
When the first damper 8 is opened, the push-stop member 4-2-2 moves close to the push-stop key 4-5 and abuts on the push-stop key 4-5. After that, the push-stop part 4-2-2 continues to move, pushing the push-stop key 4-5 to rotate, driving the driven incomplete gear 4B to rotate, thereby opening the second damper 9. After the second damper 9 is opened, the driven wheel locking outer peripheral portion 4-4 is fitted into the second opening locking recess portion 5-4-2-2.
After the first damper 8 is closed, the second damper 9 is still in an open state. The driven wheel lock outer peripheral portion 4-4 is fitted into the second opening lock recess portion 5-4-2-2.
