Abstract
An electronic device includes an air dam module. The air dam module includes a frame, a first rotating member, and a second rotating member. The frame defines a vent. The first rotating member is rotatably received in the vent, to vertically block a lower half of the vent by due to gravity. The second rotating member is rotatably received in the vent, to vertically block an upper half of the vent by due to gravity.
Claims20
An air dam module, comprising:
- a frame defining a vent through a front end and a rear end of the frame, the vent defining a substantially circular cross section;
- a first rotating member received in the vent, wherein a top side of the first rotating member is rotatably connected to the frame, the first rotating member comprises a first shield plate forming an arc-shaped bottom side with a middle of the bottom side protruding downward, the first shield plate vertically blocks a lower half of the vent by its gravity upon a condition that its gravity is not overcome by an airflow passing through the vent;
- and
- a second rotating member received in the vent, wherein a top side of the second rotating member is rotatably connected to the frame, the second rotating member comprises an arc-shaped second shield plate, opposite ends of the second shield plate are bent backwards, a top side of the second shield plate is arc-shaped, with a middle of the top side protruding upward, the second shield plate vertically blocks an upper half of the vent by its gravity upon a condition that its gravity is not overcome by an airflow passing through the vent.
