A bicycle helmet includes a body, a plurality of air inlets and a plurality of air outlets. The body includes a front portion, an upper portion, a rear portion and an inner portion. The upper portion includes a closed surface. A plurality of dimple structures are formed on the closed surface to produce an aerodynamic effect. The air inlets are formed on the front portion. The air outlets are formed on the rear portion. The inner portion includes a plurality of ribs, the ribs are positioned correspondingly to the air inlet and the air outlet and define air channels therein, an airflow flows through the body due to the airflow entering the body through the air inlets, passing through the air channels and exiting the body through the air outlets.

First claim

What is claimed is:

1 . A bicycle helmet comprising:
a body comprising a front portion, an upper portion, a rear portion and an inner portion, the upper portion comprising a closed surface and a plurality of dimple structures formed on the closed surface to produce an aerodynamic effect; a plurality of air inlets formed on the front portion; and a plurality of air outlets formed on the rear portion; wherein the inner portion comprises a plurality of ribs, the ribs are positioned correspondingly to the air inlets and the air outlets and define air channels therein, an airflow flows through the body due to the airflow entering the body through the air inlets, passing through the air channels and exiting the body through the air outlets.
