[0002] As people's demands for automotive comfort increase, the functionality of the vehicle's air conditioning system is receiving more and more attention. The airflow is adjusted by the opening angle of the damper, which is mainly adjusted by turning the damper crank with a toggle switch.

[0003] The existing damper crank connection structure is complex. In order to prevent wear when it drives the damper to rotate, a complex structure is often used to improve its robustness. However, this makes it more prone to damage during use and is also costly. Utility Model Content

[0004] The purpose of this invention is to provide a blower crank to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blowing damper crank, comprising...

[0006] Crankshaft connection section;

[0007] A pin is provided on the crank connecting shaft, and a limit block is provided at one end of the pin;

[0008] A first mounting hole is provided on the crank connecting shaft, and a single-sided mounting clip is provided on the side of the first mounting hole.

[0009] Preferably, the crank connecting shaft has a second mounting hole, which communicates with the first mounting hole and has a smaller diameter than the first mounting hole.

[0010] In any of the above embodiments, it is preferred that a second groove is provided on the crank connecting shaft portion, and the assembly-type single-sided clip is disposed in the second groove.

[0011] In any of the above embodiments, a first groove is provided between the assembled single-sided clip and the crank connecting shaft, and the first groove communicates with the second groove and the first mounting hole.

[0012] In any of the above embodiments, it is preferred that the surface of the crank connecting shaft is provided with a third groove.

[0013] The technical effects and advantages of this utility model are as follows: The blowing air damper crank adopts the structure of a first mounting hole and a second mounting hole. The connection of the blowing air damper is inserted into the first mounting hole and limited by the second mounting hole to prevent it from rotating. The assembly-type single-sided clip is inserted into the connection of the blowing air damper to complete the fixation. The structure is simple, easy to disassemble and assemble, not easy to be damaged, and has fewer structural parts, which saves more costs. Attached Figure Description
