Description

Technical Field

[0001] The utility model relates to the technical field of automotive air vents, and particularly relates to a rear air vent structure for an automobile. Background Art

[0002] Automotive air vents are one of the important interior components of an automobile. They are generally arranged inside the driver's cab or obliquely above the passenger seats. When it is necessary to adjust the temperature inside the vehicle, the air conditioner can be turned on for cooling or heating, and the air will blow out from the automotive air vents.

[0003] Currently, the design style of automobiles tends to be simplified. For the air vents located in the rear row of the vehicle, setting too many exposed components has a certain impact on aesthetics. For example, all the blades are exposed, and the upper and lower linkage rods of the blades are located inside the air outlet cavity and are also exposed. And achieving a simplified surface design style through an electric type requires setting other electronic components, which increases the manufacturing cost and maintenance difficulty.
