[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 This embodiment provides an automobile air duct device, including left and right defrost air ducts, an air duct body, an air duct partition and an upper decorative plate body. The left and right defrost air ducts, the air duct body and the air duct partition are all installed inside the upper decorative plate body. The left and right defrost and defog air ducts are connected to the air duct body by two screws, and a plurality of air outlets are opened on the upper decorative plate body; the air duct body is divided into a blowing area and a defrost area by the air duct partition.

[0022] like Figure 1-5As shown, the defrost area is divided into three areas by the left defrost air duct and the front defrost baffle 14, the right defrost air duct and the front defrost baffle 15, namely the left defrost and defrost area 1, the right defrost and defrost area 2 and the front defrost and defrost area 5. Among them, the air duct outlet of the left defrost and defrost area 1 is connected to the left defrost and defrost air duct 7, and the air duct outlet of the right defrost and defrost area 2 is connected to the right defrost and defrost air duct 6. A sealing sponge strip is set at the air duct joint to ensure the airtightness of the ventilation, so that the wind is transmitted in the air duct without causing leakage at the connection. The air duct of the front defrost and defrost area 5 leads to the cab windshield, so that the wind flows to the cab glass to defrost and defrost the cab glass. Four air outlets are provided on the air duct of the front defrosting and defogging area 5, and four guide plates 8, 9, 10, and 11 are fixedly installed at the four outlets. The airflow in the front defrosting air duct is evenly distributed and moves in a specified direction through the four guide plates 8, 9, 10, and 11. The airflow in the air duct is evenly distributed and moves in a specified direction, and the large vortex inside the air duct is eliminated to the maximum extent, the loss of wind energy is reduced, and the defrosting and defogging effect is enhanced. The wind speed of each air outlet is made more reasonable, and at the same time, the requirements of maintaining defrosting and defogging when the windshield is low are met.

[0023] like Figure 5 As shown, the four air outlets of the air duct in the front defrost and defogging area 5 are arranged in an arc shape, and the air outlets on both sides are larger than the two air outlets on the inner side.

[0024] like Figure 3 and Figure 4 As shown, the face blowing area is divided into two areas, a left face blowing area 3 and a right face blowing area 4, by left and right face blowing air duct partitions 16; the left face blowing area 3 is connected to the left face blowing air duct 12, and the right face blowing area 4 is connected to the right face blowing air duct 13. Through the direction of the air ducts, the face blowing wind enters the left face blowing air duct 12 and the right face blowing air duct 13, and then enters the air outlets of the left face blowing area 3 and the right face blowing area 4, meeting the face blowing performance requirements.

[0025] In this embodiment, the left defrost duct and the front defrost baffle 14, the right defrost duct and the front defrost baffle 15, and the left and right blowing face air duct baffles 16 are all connected to the air duct body through buckles and three screws. After being assembled into an assembly, it is connected to the upper decorative plate body by vibration friction welding, and the front defrost, side defrost, and side blowing face air ducts are integrated into one, and connected to the upper decorative plate body by welding. While effectively meeting the defrosting, defogging, and blowing face effects, it can also ensure that the instrument panel meets the design requirements. The reasonable structural design greatly simplifies the mold structure and reduces the mold cost; all the above samples are made of injection molding technology, the mold structure is simple and easy to process, and the overall strength is guaranteed.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
