The invention discloses a motorcycle helmet equipped with an unloading type brim. The motorcycle helmet comprises a helmet shell, a brim component is connected to the front end of the top of the helmet shell, a positioning member is arranged on the helmet shell, the brim component is connected to the positioning member and can swing left and right around the positioning member. According to the helmet, when the brim component is subjected to hitting and especially transverse hitting, the brim component can conduct transverse swing immediately and correspondingly, hitting power is offset by meas of resistance between the brim component and the positioning member, the phenomenon that the hitting power is transmitted to the head of a driver in a rigid mode does not exist any more, impact to the head of the driver is lowered, the driver is protected, and the safety is improved.
