[0002] Automobile air outlet is the important component of automobile interior, and it has significant effect on the comfort of automobile driving and riding. The traditional automobile air-conditioning air outlet control structure is generally composed of main blade group, secondary blade group and air door assembly, wherein the main blade group and the secondary blade group are used for air guiding, and the air door is used for controlling air volume and opening and closing of the air outlet. However, this air outlet structure has many parts, complex structure, inconvenient manufacturing and assembling, high cost, and is prone to failure due to problems of each component.

[0003] There is another air outlet structure on the market, which is mainly composed of main blade group and secondary blade group. In addition to the function of air guiding, the secondary blade group also has the function of closing the air outlet. However, the movement of the secondary blade group of this air outlet is controlled by the movement of the knob. The knob has a large movement range, which is not convenient to adjust. Moreover, the knob cannot be kept in the middle position, which destroys the overall appearance of the air outlet. SUMMARY

[0004] In view of the above-mentioned deficiencies of the electric air outlet on the current automobile, the utility model provides an electric air outlet for automobile, which has the characteristics of simple structure, beautiful appearance and stepless adjustment.

[0007] According to one aspect of the utility model, one end of the gear lever is fixedly connected with the driving blade base, and the other end is a toothed disc.

[0008] According to one aspect of the present invention, the transmission assembly includes a direct drive gear; the direct drive gear is connected to the drive shaft of a drive motor and meshes with a gear plate.

[0009] According to one aspect of the present invention, the electric blade assembly further includes a limiting mechanism; the limiting mechanism includes two limiting posts.

[0010] According to one aspect of the present invention, the blade bases are arranged in a straight line.

[0011] According to one aspect of this utility model, starting from the active blade base, the length of the linkage arm gradually decreases along the length direction of the linkage rod.

[0012] According to one aspect of the present invention, a blade connecting seat is provided on the blade base; the sub-blade is fixedly connected to the blade base through the blade connecting seat.

[0013] According to one aspect of this utility model, the sub-blade is made of a flexible material.

[0014] Advantages of this utility model:

[0015] When the air outlet is normally closed, the sub-blades are connected end to end, and the surface of the air outlet is flush.
