A plurality of mounting beams are fixed in a grid frame in parallel at intervals, an air inlet is formed between every two adjacent mounting beams, two wind shields are inserted into each mounting beam, and a motor drives the two wind shields on each mounting beam to move in the same direction or back to back at the same time. The wind shields between every two adjacent mounting beams move in the opposite direction or the opposite direction to close or open the corresponding air inlets, and the piezoelectric plates are supported on the back faces of the mounting beams in a floating mode. Grid bars of the air-inlet grille are replaced by the vortex generating device, a vortex street is formed in a wake flow area of the vortex generator through wind-induced vortex-induced vibration generated when an automobile advances, large pressure difference is formed on the two sides of the piezoelectric film, wind energy is effectively converted into electric energy, the sense of wholeness of the automobile is kept, and the service life of the automobile is prolonged. And meanwhile, the practicability of the vortex-induced vibration wind energy collector in a real wind environment is improved.
本发明公开了一种基于涡激振动的主动进气格栅,若干安装梁间隔且平行固定在格栅框内,相邻安装梁之间形成进风口,在每根安装梁内插接两个挡风板,电机驱动每个安装梁上的两挡风板同时相向或背向运动,相邻两安装梁之间的挡风板相向或背向运动对对应进风口进行关闭或打开,压电板浮动支撑在每个安装梁背面。本发明将进气格栅的栅条替换成涡发生装置,利用汽车前进时产生的风致涡激振动,在涡发生器尾流区域形成涡街,使压电薄膜两侧形成较大的压差,有效地将风能转为电能,既保持了汽车的整体感,同时又提高了涡激振动风能收集器在现实风环境中的实用性。
