Active air flap and active air flap assembly
An active air flap is provided. The active air flap includes a plurality of flaps and an elastic member bonding the plurality of flaps to form a preset angle with respect to each other. The elastic member is insert-molded between the respective flaps and a roller is coupled to the top of the active air flap with a connection member and the active air flap is wound there around by a restoring force of the elastic member. Additionally, a support bracket that rotatably supports the roller through pins protrudes from a plurality of ends of the roller, and has an aperture formed therein and the active air flap is configured to open or close the aperture.
1. An active air flap assembly, comprising:
a plurality of flaps; and
an elastic member that bonds the plurality of flaps to form a preset angle with respect to each other, wherein the elastic member is insert-molded between the respective flaps;
a roller coupled to the top of the active air flap with a connection member and having the active air flap wound there around by the elastic member;
a support bracket that rotatably supports the roller through pins that protrude from a plurality of ends of the roller, and having a aperture formed therein and the active air flap is configured to open or close the aperture;
an actuator disposed on the support bracket and configured to rotate the roller such that the active air flap opens or closes the aperture; and
an electromagnet disposed on the support bracket and coupling the active air flap to the support bracket in order to keep the aperture closed when a current is supplied.
2. The active air flap assembly of claim 1 , wherein the electromagnet is disposed at the bottom and both sides of the support bracket.
3. The active air flap assembly of claim 1 , wherein the plurality of flaps are formed of a magnetic substance.
4. The active air flap assembly of claim 1 , wherein the active air flap includes a fastening member disposed at the contact portion between the active air flap and the electromagnet.
5. The active air flap assembly of claim 4 , wherein the fastening member is formed of a magnetic substance.
6. The active air flap assembly of claim 1 , wherein the plurality of active air flap assemblies are stacked.
7. The active air flap assembly of claim 1 , wherein when an actuator error occurs or power supplied to the actuator is disengaged power supplied to the electromagnet is disengaged.
