In addition, the housing 10 is provided with a stopper 110 for limiting the rotation angle of the sector gear 94. When the rear driving shaft 90 rotates in the first time direction and the sector gear 94 contacts the limiting device 110, the air door 80 is opened; the damper 80 is closed when the rear drive shaft 90 rotates in the second clockwise direction and causes the sector gear 94 to contact the stop 110.

In order to realize the turning of the ball mouth 20, an operable air port turning driving structure is eccentrically connected to the ball mouth 20, and the air port turning driving structure is operated to push and pull the ball mouth 20. The wind gap upset drive structure that this embodiment relates to mainly includes removal fitting and upset connecting piece. Wherein the movable mating member is connected with the main shaft 30 in a mating manner and is configured to slide along the axial direction of the main shaft 30 in an operable manner; the roll-over connection is movably connected between the moving fitting and the ball opening 20, so that when the moving fitting pushes and pulls the ball opening 20 during moving, the ball opening 20 is driven to roll over in the ball bowl portion 15.
Specifically, as shown in fig. 3, 5, 6, and 8, a ring gear 40 as a moving mating member is slidably fitted on the main shaft 30, and a plurality of annular ring teeth 41 are provided on an outer wall of the ring gear 40. One end of the pull rod 50 as the flip connector is provided with a hinge shaft 52 which is hinged between two flip connecting lugs 123 on the ball socket 20 and positioned below the rotary connecting lug 122, the other end is provided with a hinge hole 51 which is hinged with the short shaft 43 on the gear ring 40, and the hinge point of the pull rod 50 and the ball socket 20 is not coincident, namely, the hinge point of the pull rod 50 and the ball socket 20 is deviated from the rotation center of the ball socket 20 at the hinged end of the pull rod 50 and the ball socket 20. When the ring gear 40 slides on the main shaft 30, the ball socket 20 can be driven by the pull rod 50 to rotate along the central axis 31 of the main shaft 30.
In the structure of slidably assembling the gear ring 40 on the main shaft 30, referring to fig. 7 and 8, two guide grooves 33 extending along the axial direction of the main shaft 30 are symmetrically arranged on the main shaft 30, two sliding bars 42 slidably engaged with the guide grooves 33 are arranged on the gear ring 40, and a short shaft 43 hinged to the pull rod 50 is arranged on each sliding bar 42. This pull rod 50 can be the working of plastics, through elastic deformation, can install on minor axis 43 to the end of this minor axis 43 is provided with the elasticity buckle that prevents pull rod 50 and withdraw from, and simple to operate just is difficult for droing.
In order to drive the axial sliding of the movable mating member on the main shaft 30, i.e. to realize the operable sliding of the movable mating member, a driving mating portion is provided on the housing 10, which is in meshing connection with the ring gear 41 to drive the ring gear 40 to slide on the main shaft 30. The driving matching part of the embodiment mainly comprises a front driving shaft 60 and a front actuator 70, wherein the front driving shaft 60 is vertical to the main shaft 30, and a front driving straight gear 61 meshed with the ring gear 41 is arranged on the front driving shaft 60; the front actuator 70 is connected to the front drive shaft 60, and when energized, the front drive shaft 60 is driven to rotate to drive the ring gear 40 to slide on the main shaft 30.
When the air port overturning driving structure of the embodiment is used, the front actuator 70 can drive the gear ring 40 to move on the main shaft 30 when being powered on under the control of a driving computer of an automobile, so that the change of the air supply direction of the ball port 20 is changed from the traditional manual adjustment into the electric adjustment, and the potential safety hazard of manually adjusting the air outlet can be eliminated. When the main shaft 30 rotates, the ring gear 41 of the ring gear 40 can always mesh with the front drive spur gear 61 of the front drive shaft 60, and therefore the front drive shaft 60 does not interfere with the main shaft 30. The ball port 20 can be rotated to a certain angle, and then the actuator 70 drives the ball port 20 to swing before use. For example, the ball port 20 is rotated to a position capable of swinging horizontally, and then the front actuator 70 drives the ball port 20 to swing horizontally, or the ball port 20 is rotated to a position capable of swinging vertically, and then the front actuator 70 drives the ball port 20 to swing vertically. In this way, the air flow direction adjustment range of the ball port 20 can be increased by superimposing the rotational movement of the main shaft 30 and the swing movement of the ball port 20.
When the rear actuator 100 rotates the rear driving shaft 90, the worm 93 of the rear driving shaft 90 can rotate the main shaft 30 through the main shaft driving gear 35 engaged therewith, and at the same time, the sector gear 94 rotates along with the rear driving shaft 90 under the action of the compression spring 92, so that the air door 80 can be opened. When the damper 80 is fully opened, the sector gear 94 can contact the limiting device 110, at this time, the sector gear 94 stops rotating, the angle of the damper 80 is not changed, and the main shaft 30 can continue to rotate under the driving of the rear driving shaft 90. When the rotation angle of the main shaft 30 and the swing angle of the ball port 20 are superimposed, the wind direction of the ball port 20 can be directed to any direction.
In the opening step of the damper 80 after the air conditioner is started, the rear driving shaft 90 is controlled to rotate to drive the main driving part to rotate, and in the rotating process of the main driving part, the two power receiving parts are driven to rotate by the auxiliary driving part to drive the damper 80 to be changed from the closed state to the conducting state. Based on the conducting state, the damper is in a fully opened state, and at this time, if the opening angle of the damper is to be adjusted, for example, based on the fully opened state, and then the opening degree of the damper 80 is reduced, a damper angle adjusting step may be provided after the damper 80 opening step, that is, the rear driving shaft 90 is controlled to rotate in the reverse direction, so as to drive the damper 80 to be changed from the conducting state to the switching state. Therefore, after the air conditioner is started, the air door 80 is firstly opened to the maximum, and then the opening degree of the air door is gradually reduced to the required opening degree, so that the air remained in the air conditioner before the air conditioner is started can be blown out completely as much as possible, and the air flow exchange effect is improved.
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.
