Description

Technical Field

[0001] The utility model relates to the technical field of automotive air conditioners, and particularly to a crank structure of an air door of an automotive air conditioner. Background Technique

[0002] The automotive air conditioning device, abbreviated as automotive air conditioner, is used to adjust and control the temperature, humidity, air cleanliness and air flow in the automotive compartment to the best state, provide a comfortable riding environment for passengers, and reduce travel fatigue; create good working conditions for the driver, and play an important role in ensuring safe driving. The ventilation device generally includes a refrigeration device, a heating device and a ventilation and air exchange device. This combined device makes full use of the limited space inside the vehicle, has a simple structure and is easy to operate. It is a popular modern automotive air conditioning system in the world. The layout methods of different types of air conditioning systems are different. The widely used air conditioning system in current cars is an integrated heating and cooling air conditioning system. Its layout form is to assemble an evaporator, a warm air radiator, a centrifugal blower, a control mechanism, etc. together, which is called an air conditioner assembly. An automotive air conditioner generally mainly consists of a compressor, an electromagnetic clutch, a condenser, an evaporator, an expansion valve, a liquid storage dryer, pipelines, a condenser fan, a vacuum solenoid valve, an idler and a control system, etc. The automotive air conditioner is divided into high-pressure pipelines and low-pressure pipelines. The high-pressure side includes the compressor output side, high-pressure pipelines, a condenser, a liquid storage dryer and a liquid pipeline; the low-pressure side includes an evaporator, an accumulator, a return air pipeline, the compressor input side and the compressor oil sump.

[0003] A high-stability air door mechanism of an automotive air conditioner with the patent number CN209719193U published on the Chinese Patent Network includes a dial body, an air door connecting rod, an air door crank and an air door. The dial body includes a dial skeleton, a rotating dial and a dial reinforcement member. The air door crank is provided with a plugging ring, and an air door hook is arranged at the outer end of the plugging ring; the structure of the utility model is simple and reasonable in design. The dial body is connected to the air door through the air door connecting rod and the air door crank. The plugging ring and the plugging hole of the air door crank are set as tapered cylindrical surfaces. An air door hook is arranged at the outer end of the plugging ring, and the air door hook is clamped in the clamping groove, which restricts the axial displacement of the air door crank. A convex block is arranged on the plugging ring, and an empty groove matching the convex block is arranged on the second connecting ring of the second mounting seat, which avoids the phenomenon of slipping when the air door crank drives the air door to rotate. However, this air conditioner air door crank does not have a disassembly component. When the air door crank is in use, it mainly relies on the engagement of the groove and the convex block for transmission. After long-term use, the convex block is prone to wear and fracture, resulting in the transmission component being unable to drive the air door to rotate in time, and it is difficult for the user to conveniently replace the crank, and the maintenance is relatively complicated.

[0004] Therefore, it is necessary to design and transform the air door crank to effectively prevent the phenomenon of the air door crank structure of the air conditioner. Content of the Utility Model
