Electric motorcycle plastic shell capable of reducing wind resistance

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle plastic shell that can reduce wind resistance. Background technique [0002] Electric vehicles, that is, electric drive vehicles, have another name called electric drive vehicles. Electric vehicles are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles use batteries as the energy source, and convert electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed of the vehicle. As a green sunrise industry, electric vehicles have been developing in China for ten years. In terms of electric bicycles, by the end of 2010, China's electric bicycles had reached 120 million, and the annual growth rate was 30%. From the perspective of energy consumption, electric bicycles are only one-eighth of motorcycles and one-twelfth of cars; from the ...

AI Technical Summary

Problems solved by technology

[0003] The current design of plastic parts of electric vehicles is various, but considering aerodynamic factors, the front face design of electric vehicles is mostly curved surface design, in order to reduce wind resistance and improve the stability of electric vehicles, but only rely on the curved surface It is designed to minimize wind resistance. In addition, the front of existing electric vehicles is basically equipped with a basket, which will increase wind resistance and invisibly increase the instability of electric travel.
