As shown in fig. 1 to 6, an exemplary embodiment of the present invention provides an automobile tail, which includes a tail upper plate 1 and a tail lower plate 2 connected to the tail upper plate 1, wherein a cavity 3 is formed between the tail upper plate 1 and the tail lower plate 2.

At least two connecting bases 20 for connecting with a tail door metal plate 201 of an automobile are arranged at intervals at the lower part of the tail lower plate 2.

An airflow passage 4 capable of guiding an airflow toward a rear door glass 202 of an automobile is formed between two adjacent connection bases 20.

The tail lower plate 2 has a windward surface 21 and a blowing surface 24 located on the rear side of the windward surface on the bottom surface facing the airflow path 4.

The windward side 21 includes a windward plane 211 located at the front and a windward curved surface 212 located at the rear of the windward plane 211; the windward curved surface 212 is convex toward the inside of the airflow passage 4. The air blowing surface 24 is an air blowing plane 241.

The distance between the windward curved surface 212 and the tail upper plate 1 becomes gradually larger and the distance between the blowing plane 241 and the tail upper plate 1 becomes gradually smaller in the front-to-rear direction.

The automobile tail wing provided by the invention is mainly used for being arranged at the tail part of an automobile, on one hand, the tail part of the automobile can be balanced, and on the other hand, the air flow can be guided to the tail door glass 202, so that the tail door glass can be cleaned, and a tail door glass wiper is not required to be specially arranged on the tail door.

The automobile tail wing provided by the embodiment of the invention comprises a tail door upper plate 1 and a tail door lower plate 2, wherein the tail door lower plate 2 is assembled below the tail door upper plate 1. A sealed cavity 3 is formed between the tail gate lower plate 2 and the tail gate upper plate 1.

More than two connecting bases 20 are arranged at the bottom of the tail gate lower plate 2 at intervals, and the connecting bases 20 are used for being connected with a tail gate metal plate 201 so as to install the automobile tail fin on the automobile tail gate.

The airflow passage 4 is formed between adjacent two of the connection bases 20. After the car tail fin is installed on the car tail gate, the air flow path 4 is located between the bottom surface of the tail fin lower plate 2 and the tail gate glass 202.

The tail lower panel 2 has a front face 21 at the bottom surface thereof and a blowing surface 24 at the rear thereof. The windward and the blowing referred to here are only relative concepts. The windward side 21 is located on the side of the inlet of the airflow channel 4, which faces the airflow. The blowing surface 24 is located on the side of the outlet of the air flow path 4, which follows the air flow.

The windward side 21 includes a windward flat surface 211 and a windward curved surface 212, the windward flat surface 211 is located at the front of the windward curved surface 212, and the windward curved surface 212 is convex toward the inside of the airflow passage 4, so that a step is formed at the front end of the windward curved surface 212 and the rear end of the windward flat surface 211. The windward plane 211 is arranged at the front part of the windward curved surface 212, so that the front end of the windward curved surface 212 is prevented from extending forwards too much, and wind noise is not controlled favorably.

The windward plane 211 is substantially parallel to the top surface of the tailgate upper panel 1, and has an effect of guiding the atmospheric air of the air inlet of the airflow passage 4 to flow toward the windward curved surface 212, and is capable of smoothing the airflow. The windward curved surface 212 protrudes towards the inside of the airflow channel 4, so that the effective ventilation area of the airflow channel 4 is reduced or the airflow channel 4 becomes thin, the length of the steady flow section is increased while the airflow direction is changed, the airflow circulation speed can also be increased, and the airflow is favorably blown to the tail gate glass for cleaning.

The blowing plane 241 is arranged obliquely. The top of the upper tail panel 1 is a substantially flat plate.

The windward curved surface 212 and the air supply plane 241 are arranged in the following way: the distance between the windward curved surface 212 and the tail upper plate 1 becomes gradually larger and the distance between the blowing plane 241 and the tail upper plate 1 becomes gradually smaller in the front-to-rear direction.

By the arrangement, the inlet of the airflow channel 4 is reduced from large to small, and the windward curved surface 212 is a curved surface and is convex towards the inside of the airflow channel 4, so that airflow can be guided to be pressed downwards, and the tail gate glass 202 can be cleaned conveniently.

The arrangement is such that the outlet of the air flow passage 4 is made smaller and larger, and the air supply plane 24 is a plane, so that the air flow can be diffused quickly after passing through the narrowest part of the air flow passage 4.

Therefore, the automobile tail wing provided by the invention is used for guiding the air flow to the tail gate glass 202 by forming the air flow channel 4 at the lower part of the automobile tail wing, so that the surface of the tail gate glass 202 is cleaned, and the dust on the tail gate glass 202 can be cleaned by blowing away impurities on the tail gate glass 202 through the air flow. When the vehicle is driven in rainy days, rainwater on the tail gate glass 202 can be blown away by airflow blown to the tail gate glass 202 from the airflow channel 4, the rainwater on the tail gate glass 202 can be cleaned, the effect of cleaning the tail gate glass 202 can be realized without specially arranging a tail gate glass windshield wiper, the structure of the tail gate is simplified, and the product quality is improved.
