[0036] Example 1

[0037] Please see Figure 1-7 This utility model provides a technical solution: a car air conditioning vent structure, comprising:

[0038] Casing 1;

[0039] The partition component 2 includes a support shell 21 disposed in the middle of the housing 1;

[0040] The upper blade assembly 3 includes a plurality of first blades 31 disposed on the upper side of the support shell 21. The first blades 31 are rotatably mounted on the support shell 21 and are pivotally connected to the upper linkage rod 32.

[0041] The lower blade assembly 4 includes a plurality of second blades 41 disposed on the lower side of the support shell 21;

[0042] The air guide plate 5 is rotatably mounted on the housing 1;

[0043] The position of the air guide plate 5 corresponds to the support shell 21.

[0044] The lower blade group 4 and the upper blade group 3 have the same installation structure and the same working principle.

[0045] An extension edge 53 is provided on the back of the air guide plate 5, and an arc-shaped groove 211 corresponding to the extension edge 53 is provided on the support shell 21. The extension edge 53 of the air guide plate 5 contacts the bottom surface of the arc-shaped groove 211, and the air guide plate 5 is positioned by the support shell 21 to ensure that the air guide plate 5 swings smoothly.

[0046] Working Principle: Inside the housing 1 of the automotive air conditioning vent, the upper blade assembly 3 and the lower blade assembly 4 are respectively arranged on the upper and lower sides of the support housing 21. Multiple first blades 31 in the upper blade assembly 3 can rotate synchronously via the upper linkage rod 32 to adjust the horizontal airflow direction. Similarly, multiple second blades 41 in the lower blade assembly 4 can rotate synchronously via the lower linkage rod to adjust the airflow direction. Furthermore, the air guide plate 5 on the front side of the support housing 21 can swing vertically up and down, obstructing the airflow from either the upper or lower blade assembly 4, thereby adjusting the airflow volume on both sides of the support housing 21. This significantly improves the flexibility of airflow adjustment, meets different airflow needs, and enhances the adjustment effect. In addition, compared to traditional vent adjustment components, the air guide plate 5 has a larger area, making it easier to operate.

[0047] Example 2

[0048] Based on the above embodiments, this embodiment further improves upon the following technical solutions: a transmission wheel 52 is provided at one end of the air guide plate 5, and a plurality of first meshing teeth are arranged circumferentially on the transmission wheel 52.
