Specifically, the air guiding portion 2041 is an arc-shaped blade connected between the outer annular plate 205 and the middle annular plate 206, and each blade gradually inclines to one side as approaching the air outlet, and the inclination directions of the blades are the same, so that the air outlet effect of the external air outlet duct 204 can be enhanced, and the structural strength of the globe mouth 2 can be enhanced. In addition, still include and arrange the reinforcing plate 208 that roughly is "X" shape on inner ring plate 207 inner wall, four ends of reinforcing plate 208 are passed through inner ring plate 207 after and are linked firmly with the inner wall of well ring plate 206, not only can further strengthen the effect of bulb mouth 2 structural strength, still can strengthen the effect of gathering the air-out.

When the pivot shaft 301 rotates to cause the ball port 2 to turn left and right and deviate from the center position, the sliding member 401 drives the ball port 2 to turn back and forth, and if the transmission connection mode of the sliding member 401 and the ball port 2 is fixed point connection, interference between the motion path of the ball port 2 and the motion path of the sliding member 401 occurs, and the back and forth turning is blocked. In order to solve the above problem and avoid interference in the transmission of the ball port 2 by the two sets of driving mechanisms of the tumble driving member 3 and the tumble driving mechanism 4, as shown in fig. 10, an arc-shaped slide groove 402 is formed in one of the slide member 401 and the ball port 2, and a slide block 403 fitted in the slide groove 402 is formed in the other of the slide member 401 and the ball port 2.

The transmission form of the gear and the rack is adopted, so that the arrangement of the driving mechanism is convenient, and the high-efficiency transmission and speed reduction performance is realized.

To further change the transmission ratio of the tumble drive mechanism 4 and to facilitate the arrangement and installation of the tumble drive mechanism 4, as shown in fig. 10, the tumble drive mechanism 4 further includes an intermediate drive member 405, and the intermediate drive member 405 has an intermediate drive shaft 4052 detachably connected to the drive gear shaft 4042 and coaxially disposed, and an intermediate drive gear 4051 attached to the intermediate drive shaft 4052 to rotate the intermediate drive shaft 4052.

As shown in fig. 2, the driving gear shaft 4042 and the intermediate driving shaft 4052 are respectively inserted into the two shaft holes 1031 and are connected in a snap-fit manner, so as to mount the sliding driving member 404 and the intermediate driving member 405 on the mounting frame 103 of the housing 1, which facilitates the assembly of the turnover driving mechanism 4 and helps to improve the assembly efficiency.

As shown in fig. 10, the flipping drive mechanism 4 is further equipped with a rear actuator 406, and the rear actuator 406 drives the sliding member 401 to slide through a transmission component, so that the flipping drive of the ball socket 2 by the flipping drive mechanism 4 can be well realized. Specifically, the rear actuator 406 is drivingly connected to the intermediate drive gear 4051, and when the rear actuator 406 is energized, the intermediate drive gear 4051 is driven to rotate about the intermediate drive shaft 4052, so as to drive the drive gear shaft 4042 to rotate the slide drive gear 4041.

When the air conditioner air outlet path regulating mechanism of the embodiment is assembled, firstly, the sliding block 403 at one end of the sliding part 401 is placed in the sliding groove 402, the ball port 2 connected with the sliding part 401 is installed in the port 101 of the casing 1, and the sliding part 401 is ensured to slide into the arc-shaped through hole 102 of the casing 1; then, the pivot shaft 301 of the turnover driving member 3 is inserted into the rotation shaft hole reserved right below the port 101, and the ball port 2 and the turnover driving member 3 are assembled into a whole. The lower actuator 303 of the tumble drive member 3 is then secured to the housing of the casing 1. Thereafter, the end cap 104 is fitted to the end of the housing 1.

Obviously, the lower actuator 303 and the rear actuator 406 are provided with detection elements for detecting the rotation angle of the driving motor, so that the driving rotation angles of the turnover driving member 3 and the turnover driving mechanism 4 can be known in real time; and the turning angle of the ball mouth 2 in the corresponding turning axial direction can be calculated and determined through the transmission ratio of the turning driving component 3 and the turning driving mechanism 4.

The appointed air-out direction can be decomposed into two upwards turnover angles of two turnover shafts, so that the matching drive of the turnover drive component 3 and the turnover drive mechanism 4 is finally realized, and the ball mouth 2 reaches the appointed air-out direction. Meanwhile, an automatic swinging air outlet mode and path of the ball mouth 2 can be preset in the vehicle-mounted control system, and then the control unit controls the overturning driving component 3 and the overturning driving mechanism 4 to realize that the ball mouth 2 automatically swings and changes air outlet towards each direction in the vehicle.

By adopting the air outlet air path regulating mechanism of the air conditioner, the electric regulation of the air outlet direction of the ball opening 2 can be well realized.

According to the air conditioner air outlet flow adjusting mechanism, the air outlet condition of the ball opening and the air flow flowing through the internal channel 105 in the automobile air conditioner shell 1 can be controlled and adjusted by overturning the ball opening 2 and improving the structure of the shell 1 and the opening and closing mode of the air channel, so that the air outlet converging or diverging effect can be realized, and the comfort of passengers can be improved.
