Abstract

A magnetic liquid damping shock absorber includes a housing, a thermal insulating material layer, a mass block and a magnetic liquid. The housing defines a sealed cavity, the sealed cavity has a first wall face and a second wall face opposite in a first direction and a circumferential wall face located between the first wall face and the second wall face in the first direction. The thermal insulating material layer is provided on an outer surface of the housing, on a wall face of the sealed cavity or in a housing wall of the housing. The mass block is located in the sealed cavity, and the mass block and the housing define a magnetic liquid cavity therebetween. The magnetic liquid is filled in the magnetic liquid cavity.
