The invention belongs to the technical field of automobile vibration reduction and noise reduction, and particularly relates to a local resonance type metamaterial wiper blade which comprises a wiper blade body, a first cavity is formed in the center of the wiper blade body in the length direction, and a plurality of vibration reduction structures are fixedly connected to the inner side of the first cavity at equal intervals in the length direction; the vibration reduction structure comprises a plurality of connecting arm structures which are arranged at equal intervals in the circumferential direction, one ends of the connecting arm structures are fixedly connected with the inner side of the first cavity, the other ends of the connecting arm structures are fixedly connected with the same resonance structure, and the center of the resonance structure is fixedly connected with a local resonance vibrator. By means of the structures, the local resonance type metamaterial wiper blade is combined with the metamaterial design concept, vibration generated in the actual movement process of the wiper blade can be restrained, noise generated in the wiping process is reduced, and the cleaning effect is improved.

    本发明属于汽车减振降噪技术领域,尤其涉及一种局域共振型的超材料雨刮片,包括:雨刮片本体,所述雨刮片本体中央沿长度方向开设有第一空腔,所述第一空腔内侧沿长度方向等间距固定连接有若干个降振结构;所述降振结构包括若干个周向等间距排列的连接臂结构,所述连接臂结构一端与所述第一空腔内侧固定连接,所述连接臂结构另一端固定连接有同一共振结构,所述共振结构中心固定连接有局域共振振子。利用这些结构,本发明实现了一种结合了超材料设计理念,能够抑制雨刮片在实际运动过程中产生的振动,降低刮刷过程中产生的噪声,提高清洁效果的局域共振型的超材料雨刮片。
