The invention relates to the technical field of electric vehicle parts, in particular to an electric vehicle wind power generation device which is integrally suitable for being fixed to an electric vehicle and comprises a transmission unit and a power generation unit. The transmission unit comprises a first transmission rod; the first transmission rod can do linear reciprocating motion in the axial direction. The power generation unit comprises a generator and blades; the generator sleeves the middle part of the transmission rod and is internally provided with a stator and externally provided with a rotor; the plurality of blades are uniformly distributed along the circumferential direction of the rotor; the root of each blade is rotationally connected with the rotor and the first transmission rod; the roots of the blades are driven by the first transmission rod so that the tips can be close to each other to be folded or far away from each other to be unfolded. When the electric vehicle is parked temporarily or parked for a long time, the wind power generation device of the electric vehicle is in an unfolded state, and the power generation device can generate power through wind energy. When the electric vehicle runs, the wind power generation device of the electric vehicle is in a folded state, and the occupied space is greatly reduced.
本发明涉及电动车零配件技术领域,具体为一种电动车风力发电装置,其整体适用于固定在电动车上,包括传动单元和发电单元;传动单元包括第一传动杆;第一传动杆能够沿轴向作直线往复运动;发电单元包括发电机和叶片;发电机套设于传动杆的中部,内部设有定子,外部设有转子;叶片为多个,沿转子的周向均匀分布;每个叶片的根部分别与转子、第一传动杆转动连接;多个叶片的根部由第一传动杆带动,以使尖部相互靠近合拢或远离展开。当电动车短暂驻车或长期驻车时,电动车风力发电装置处于展开状态,发电装置能够利用风能进行发电。当电动车行驶时,电动车风力发电装置处于收拢状态,所占空间大幅度下降。
