The invention relates to the technical field of automobile silencers, in particular to a silencer valve body structure and a mute type automobile silencer, which comprises a valve body air inlet cylinder, a connecting elastic piece, a valve cover, a valve body bracket, a driving mechanism and a sealing damping part, the valve cover is used for covering the first extension part so as to block the valve body air inlet cylinder; a driving mechanism is arranged on the valve body support and used for increasing the pressing force of the valve deck and the valve body air inlet cylinder. And a sealing damping part is arranged between the valve cover and the first extension part. The valve cover is pressed through the combined action of the reset elastic piece and the connecting elastic piece, after exhaust airflow is increased, air pressure pushes away the valve cover, the air pressure difference is reduced, the valve cover is kept at a certain position, and the force of the air flow pushing away the valve cover is
