The second power receiving part 602 and the second driving part 603 which are matched in gear transmission are constructed into a full gear transmission structure, so that the driving adjustment of the middle air door 6 can be realized, a continuous rotation condition is provided for the second rotating shaft 601 which is used for driving the peripheral air door 5, and the arrangement of the first power receiving part 502 for driving the peripheral air door 5 is convenient.
In order to make the arrangement of the driving and transmission components of the outer peripheral damper 5 and the middle damper 6 more reasonable and facilitate the overall arrangement design, it is preferable that the second power receiving portion 602 and the first driving portion 503, both provided on the second rotating shaft 601, are disposed on both sides of the middle damper 6 as shown in fig. 8.
In this embodiment, as shown in fig. 1 and 2, at the air outlet of the vehicle air conditioner, a matching ball 20 is disposed in the dual-channel structure of the air-conditioning outlet duct air path control mechanism of this embodiment, so that the air flow conditioned by the air-conditioning outlet duct air path control mechanism can have a better air outlet effect at the air-conditioning outlet.
Specifically, a ball socket 20 is provided on the ball bowl part 15 of the housing 10 in a reversible manner; the structure of the globe 20 is shown in fig. 4, a middle air outlet channel matched with the middle channel 107 and an outer air outlet channel matched with the outer channel 108 are formed on the globe 20, and a plurality of air guide blades are formed in the two air outlet channels to form good guide for air outlet of the air conditioner.
In order to provide an actuating mechanism with a simple design and easy technical implementation for the main driving shaft 7, in this embodiment, the air path control mechanism of the air conditioner air outlet duct further includes a lower actuator 701 in transmission connection with the main driving shaft 7, and preferably, the lower actuator 701 is a stepping motor or a servo motor. When the lower actuator 701 is energized, the main drive shaft 7 is driven to rotate to drive the middle damper 6 to open and close the middle passage 107 and the outer damper 5 to open and close the outer passage 108. Obviously, a detection element for detecting the rotation angle of the motor should be installed in the lower actuator 701, so that the driving rotation angle of the main driving shaft 7 can be known in real time; and the rotation angles of the outer damper 5 and the middle damper 6 and the opening and closing states of the middle passage 107 and the outer passage 108 can be calculated and determined through the transmission ratio among the gears.
When the air-conditioning air outlet channel air path control mechanism described in this embodiment is used, a preferable technical scheme is that an air-conditioning air outlet mode can be set through operation of a vehicle-mounted control unit, and the control unit drives the lower actuator 701 channel to act to drive the four different states of the outer damper 5 and the middle damper 6 relative to the middle channel 107 and the outer channel 108: the fully conducting state, the fully closed state, the middle part conducting and the periphery closed state, and the middle part closing and the periphery conducting state.
Under the state of difference, the air-out of ball mouth 20 is dispersed or is assembled the form and produce corresponding transform, corresponds different states, can form the whole air-outs of middle part exhaust stack and outside exhaust stack, middle part exhaust stack and outside exhaust stack do not go out the air at all, the middle part exhaust stack assembles the air-out and the cyclic annular different effect of dispersing the air-out of outside exhaust stack to satisfy the different needs of automobile passenger.
The air-conditioning air outlet channel air path control mechanism can well control and adjust air flow flowing through the internal channel 13 in the automobile air-conditioning shell 10, so that the air-conditioning air outlet effect is improved.
By combining the technical scheme in the embodiment, the air conditioner air door of the air conditioner air outlet channel air path control mechanism adopts the following control method:
the first step is as follows: when the automobile air conditioner is started, the outer peripheral air door 5 and the middle air door 6 are both in the original full-closed state, the full closing of the middle passage 107 and the outer peripheral passage 108 is formed, and the angles of the rotating directions shown by alpha, beta, gamma and omega in fig. 8 are defaulted to 0 degrees.
The second step is that: by operating or setting the vehicle-mounted control unit to control the lower actuator 701 to act, the lower actuator 701 drives the main driving shaft 7 to rotate in the rotation direction α shown in fig. 8, drives the second power receiving portion 602 and the second rotating shaft 601 to rotate 90 ° in the rotation direction β shown in the figure, and the middle damper 6 is switched from the middle closed state to the middle open state, thereby forming the single opening of the middle passage 107.
The third step: the lower actuator 701 continues to act to drive the main driving shaft 7 to continue to rotate along the rotation direction shown by alpha in fig. 8, so as to drive the second power receiving part 602 and the second rotating shaft 601 to rotate to 180 degrees along the rotation direction shown by beta in the figure, and 6 is switched from the middle conduction state to the middle closing state; in the process, the two first driving portions 503 respectively drive the two first rotating shafts 501 to rotate 90 ° along γ and ω in the figure, so as to drive the two outer periphery dampers 5 to switch from the outer periphery closed state to the outer periphery open state, thereby forming independent opening of the outer periphery passage 108.
The fourth step: the lower actuator 701 continues to act to drive the main driving shaft 7 to continue to rotate along the rotation direction α shown in fig. 8, so as to drive the second power receiving portion 602 and the second rotating shaft 601 to rotate to 270 ° along the rotation direction β shown in the figure, and the middle damper 6 is switched from the middle closed state to the middle open state, so that the middle passage 107 and the peripheral passage 108 are all opened.
The outer peripheral damper 5 and the middle damper 6, which have completed the above three conducting states, are driven by the reverse action of the lower actuator 701 to rotate the main drive shaft 7 against the rotation direction α shown in fig. 8 to return to the original 0 ° position, thereby driving the outer peripheral damper 5 and the middle damper 6 to return to the original fully closed state, resulting in the complete closing of the middle passage 107 and the outer peripheral passage 108.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
