The invention relates to an engine suspension vibration reduction structure and system and an automobile. The engine suspension vibration reduction structure comprises a storage battery structure anda suspension support. The storage battery structure comprises a storage battery frame, a storage battery body arranged in the storage battery frame, a storage battery bottom plate arranged at the bottom of the storage battery body a storage battery support plate arranged outside the storage battery body, having the top connected with the top face of the storage battery frame, and the bottom connected with the storage battery bottom plate, and a plurality of elastic elements uniformly arranged between the storage battery body and the storage battery frame; the suspension support is arranged atthe bottom of the storage battery structure, and the resonant frequencies in multiple directions are different; the plurality of elastic elements are respectively positioned in a plurality of directions of the storage battery body, the rigidities of the elastic elements in the plurality of directions are different, and the rigidities of the elastic elements in the plurality of directions are in one-to-one correspondence with the resonant frequencies of the suspension bracket in the plurality of directions, so that a dynamic vibration absorption effect is achieved, and an additional dynamic vibration absorber does not need to be added.
本发明涉及一种发动机悬置减振结构、系统及汽车,该发动机悬置减振结构包括蓄电池结构及悬置支架;蓄电池结构包括蓄电池框架,设于蓄电池框架内部的蓄电池本体,设于蓄电池本体底部的蓄电池底板,布置于蓄电池本体外部、且顶部与蓄电池框架的顶面连接、底部与蓄电池底板连接的蓄电池支架板,以及均匀布置于蓄电池本体与蓄电池框架之间的多个弹性元件;悬置支架设于蓄电池结构的底部,在多个方向上的共振频率各不相同;其中,多个弹性元件分别位于所述蓄电池本体的多个方向,多个方向上的弹性元件的刚度各不相同,且多个方向上的弹性元件的刚度与悬置支架在多个方向上的共振频率一一对应,从而起到动力吸振的作用,不需要增加额外的动力吸振器。
