The invention discloses an automobile noise absorbing and insulating device capable of recycling noise energy, aiming to overcome the problem that in the prior art, the noise energy recycling cannot be realized while the automobile noise cannot be effectively reduced. The automobile noise absorbing and insulating device includes two acoustic packaging devices that are applied to an automobile front-wheel fender inner liner, an engine compartment cover, and a front coaming plate. each of the two acoustic packaging devices is composed of a first part, taking the effects of noise absorbing and insulating and realizing noise energy collection and conversion, namely, a first noise collecting plate, a second noise collecting plate, a Helmholtz resonator or a perforated panel, a first piezoelectric film, a second piezoelectric film, a rectification circuit board and a super capacitor, and a second part being called sound insulating materials, and the second part takes the effect of further noise reduction. a first l
