The invention discloses an electric motorcycle plastic shell capable of reducing wind resistance, and relates to the technical field of electric motorcycles. The electric motorcycle plastic shell comprises a front electric motorcycle body, a bottom plate and a rear electric motorcycle body; a ventilation opening is formed in an inner cavity of the front electric motorcycle body; a grid panel is arranged at an air inlet of the ventilation opening; an electric motor is arranged in an inner cavity of the ventilation opening; a rotating shaft is fixedly connected to the left side of the electric motor; an outer ring of the rotating shaft is equipped with fan blades; a trim panel is provided at an air outlet of the ventilation opening; a storage battery assembly is arranged on an upper portion of the inner cavity of the front electric motorcycle body; a supporting column is fixedly connected to the middle of the top of the front electric vehicle body; and an inner cavity of the supporting column is movably connected with a roof rack. When the blades rotate, an electric motorcycle plastic part can drive an airflow from the grid panel to enter the ventilation opening, and the airflow can accelerate the rotation of the fan blades, so that electric energy consumption can be reduced and and an energy-saving effect is achieved; besides, an internal airflow is blown out forwards through the blades, and a local airflow direction is changed, so that the influence caused by wind resistance can be further reduced.

    本发明公开了一种可降低风阻的电动车塑件外壳,涉及电动车技术领域,包括前电动车身、底板、后电动车身,前电动车身的内腔开设有通风口,通风口的进风口处设置有栅格面板,所述通风口的内腔设置有电动马达,电动马达的左侧固定连接有转动轴,转动轴的外圈套装有风机叶片,通风口的出风口处设置有饰面板,前电动车身内腔的上部设置有蓄电池组件,前电动车身顶部的中部固定连接有支柱,支柱的内腔活动连接有车顶架,该电动车塑料件在叶片转动时,可以带动气流从栅格面板进入到通风口内,气流可以加速风机叶片的转动,可以减少电能消耗,起到节能作用,再由叶片将内部气流向前方吹出,改变局部气流方向,继而可以再度降低风阻带来的影响。
