Description

Technical Field

[0001] The utility model relates to the technical field of automobile air conditioners, in particular to a surface-blowing air door linkage mechanism. Background Art

[0002] As the country vigorously advocates energy conservation and emission reduction, automotive air conditioners are also constantly innovating to meet the national energy conservation and emission reduction policies. The OEM also requires the air conditioning box to be lightweight and miniaturized. To reduce the size of the air conditioning box while meeting the performance, it is necessary to make the air conditioning box structure more compact. According to the boundary condition design, the front blowing face air duct and the rear blowing face air duct cannot use one damper to achieve the opening and closing function. We designed two dampers to be controlled separately, but due to the boundary conditions, it is impossible to design a linkage structure outside the air conditioning box. It is necessary to design a linkage mechanism in the air conditioning box flow channel to realize the synchronous rotation of the two dampers. Since the structure is designed in the flow channel, the internal resistance of the flow channel will increase, affecting the air volume and noise. For this reason, a blowing face damper linkage mechanism is proposed to solve the problem. Utility Model Content
