Abstract

The present invention relates to an air conditioner for a vehicle, which includes an air-conditioning case (200), and at least one door (100) mounted to be opened and closed at a predetermined position, wherein the door (100) is formed integrally with an arm pivot (140), and the arm pivot (140) includes a pin part, and ribs formed integrally with both sides of the pin part to reinforce rigidity of the pin part and offset noise. The air conditioner further includes distortion preventing parts formed on a rotary shaft to be dented and to be crossed to each other, thereby reducing a transformation rate of the door and securing accuracy of the pin part.

First claim

What is claimed is:

1. A door for an air conditioner for a vehicle, wherein the air-conditioner includes an air-conditioning case, wherein the door is mounted to the air-conditioning case to be moved to predetermined positions, and wherein the door comprises:
a plate for opening and closing at least one among an air passageway and an air outflow port disposed in the air-conditioning case;
a shaft connected to the plate and rotatable about an axis for rotating the plate;
an arm part connected to the shaft, wherein at least a part of the arm part is configured to protrude through the air-conditioning case an outside of the air-conditioning case; and
a leak preventing part disposed on the arm part to prevent a leak between the door and the air-conditioning case.

2. The door according to claim 1 , wherein the leak preventing part extends annularly about the axis.

3. The door according to claim 2 , wherein the leak preventing part is located along an outer perimeter of the arm part.

4. The door according to claim 1 , wherein the leak preventing part protrudes from the arm part and is formed to come into contact with the air-conditioning case.

5. The door according to claim 1 , wherein the air-conditioning case includes a protrusion located between the leak preventing part and the arm part.

6. The door according to claim 5 , wherein the protrusion is located radially between the leak preventing part and the arm part.

7. The door according to claim 6 , wherein an end portion of the leak preventing part, which comes into contact with the air-conditioning case, has an inclined surface tapered along the air-conditioning case.

8. The door according to claim 1 , wherein the leak preventing part is connected with a sealing part formed on an edge of the plate and is doubly injection-molded.

9. The door according to claim 1 , wherein the shaft is formed integrally with the plate.

10. The door according to claim 1 , wherein the arm part is formed integrally with the shaft.

11. The door according to claim 1 , wherein the leak preventing part is axially shorter than the arm part.

12. The door according to claim 1 , wherein the arm pivot includes a pin part protruding from a location adjacent to an end of the shaft for being received by an elongated hole in the air-conditioning case.

13. The door according to claim 12 , wherein the leak preventing part extends annularly about the axis radially outside of the pin part.

14. The door according to claim 12 , wherein the leak preventing part is axially shorter than the pin part and an end of the shaft in a direction toward the air conditioning case.
