The invention provides an energy absorption type rear protection mounting structure which comprises a pressure-bearing frame body and a fixed frame body, one end of the fixed frame body is fixedly connected to a vehicle bearing beam, an energy absorption device is mounted at the other end of the fixed frame body through the pressure-bearing frame body, and the fixed frame body comprises two sets of supports which are symmetrically arranged and are the same in structure. The fixed frame body comprises a first deformation frame, a second deformation frame, a first pressure-bearing rod and a first connecting rod, one side of the first deformation frame and one side of the second deformation frame are fixedly connected to the vehicle bearing beam through the supports respectively, and the first connecting rod and the supporting structure are arranged between the first deformation frame and the second deformation frame respectively. The first connecting rod and the supporting structure arearranged in parallel. According to the energy absorption type rear protection mounting structure, a specific mounting mechanism needing to be configured for a special tearing and deforming mode of anenergy absorption device is met, the structure is simple, manufacturing is convenient, the light weight and NVH performance are met, and the structural reliability is high.
