Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and more specifically to an automobile air outlet. Background Art

[0002] Car air-conditioning vents are essential components of a car. To meet the temperature requirements of drivers of different heights, body shapes, and habits, the air-conditioning vents rotate along the center of rotation to obtain the customary wind speed and temperature.

[0003] Currently, there are two types of automotive air conditioning vents on the market. One type uses purely manual control of air direction, which adjusts air direction by controlling the upper and lower air guide vane assemblies, left and right air guide vane assemblies, dampers, and other components. While this type of solution is simple and mature, its disadvantage is that it cannot meet the needs of the development trend of intelligent and electrified vehicle interior control modes.

[0004] The second type is a multi-actuator electric air outlet. The principle is that each electric actuator controls the upper and lower air guide blade assemblies, the left and right air guide blade assemblies, etc. The defect of this type of air outlet is that the transmission mechanism uses multiple linked gears to connect between the actuator and the blades. The mechanism is relatively complex and the cost is relatively high. In addition, there are problems with poor operational reliability and large space occupation. Utility Model Content

[0005] In view of the shortcomings and defects of the existing technology, an automobile air outlet is provided which has good air outlet effect, compact structure, and stable and reliable operation.

The matching groove is provided at the tail end of a swing arm, and the front end of the swing arm is hinged to the tail ends of the two upper and lower wind guide blades respectively.

[0025] The pin body enters the matching groove, and when the spur gear rotates, the pin body travels in the matching groove to drive the transmission frame to rotate up and down, thereby driving the upper and lower air guide blades to swing up and down.

[0026] As an improvement of the present invention, the spur gear ring is arranged on the left side of the input gear, and the spur gear is arranged in front of the input gear;
