The invention discloses an automobile vibration and noise reduction device, and belongs to the technical field of automobile vibration and noise reduction devices. Comprising a noise reduction structure, the noise reduction structure comprises an engine hood, a butt joint structure and a first vibration reduction structure are arranged on the upper end face of the engine hood, and the butt joint structure limits the first vibration reduction structure; the side face, driving the engine hood, of the first vibration reduction structure is connected with the limiting structure, and the limiting structure is connected with the second vibration reduction structure. The second vibration reduction structure drives the first vibration reduction structure to abut against the engine. The first vibration reduction structure is arranged on the noise reduction structure, the contact area between the noise reduction structure and an engine is increased, the noise reduction structure is more stable in stress, meanwhile, under cooperation of the first vibration reduction structure, the positions of the noise reduction structure and the engine are constant, and the noise reduction effect is improved; by arranging the limiting structure, the limiting structure is connected with the second vibration reduction structure, vibration generated between the engine and the noise reduction structure is reduced, and the vibration reduction and noise reduction effect is improved.
本发明公开了一种汽车减振降噪装置,属于汽车减振降噪装置技术领域;包括降噪结构,降噪结构包括发动机罩,所述发动机罩的上端面设有对接结构和第一减振结构,对接结构对第一减振结构进行限位;所述第一减振结构驱动发动机罩的侧面与限位结构连接,限位结构连接第二减振结构;所述第二减振结构带动第一减振结构与发动机抵触。本发明通过在降噪结构上设有第一减振结构,增大了与发动机的接触面积,使降噪结构受力更加稳定,同时在第一减振结构的配合下,使降噪结构与发动机的位置恒定,提高了降噪效果;通过设置限位结构,限位结构连接第二减振结构,减小发动机与降噪结构之间产生的振动,提高减振降噪效果。
