The invention relates to an electronic compound shock absorber, in particular to a sealing structure of the electronic compound shock absorber. The sealing structure comprises a leather bag, a steam storage cylinder and an upper plastic part. One end of the leather bag is connected to the upper plastic part while the other end of the leather bag is connected to the steam storage cylinder, two endsof the leather bag are separately arranged on the steam storage cylinder and the upper plastic part in a sleeving manner, sealing elements are arranged between the leather bag and the steam storage cylinder and between the leather bag and the upper plastic part, the leather bag and the steam storage cylinder and the leather bag and the upper plastic part are fixed through pressure rings, the sealing elements comprise a plurality of sealing grooves formed in the outer side faces of the upper plastic part and the steam storage cylinder and a plurality of sealing teeth hermetically arranged on the leather bag and matched with the sealing grooves, and the sealing grooves and the sealing teeth are arranged spirally. The invention aims to provide the sealing structure of the electronic compoundshock absorber, wherein the sealing structure is good in sealing effect and it is unlikely to leak air between the leather bag and the steam storage cylinder and between the leather bag and the upperplastic part.
