The invention relates to an automobile hydraulic energy absorption safety device. The automobile hydraulic energy absorption safety device is characterized by comprising primary energy absorbers, a primary energy absorber support, a secondary absorber, a hydraulic oil storage tank, an oil pump and one-way valves, wherein the primary energy absorbers are arranged on the front side of the primary energy absorber support, the secondary energy absorber is arranged on the rear side of the primary energy absorber support, an oil outlet pipe and an oil return pipe are arranged in the primary energy absorber support, the primary energy absorber support is communicated with the primary energy absorbers through the oil inlet one-way valve and the oil outlet one-way valve, and the secondary energy absorber is directly communicated with the primary energy absorber. An oil pump is arranged between the oil outlet pipe and the hydraulic oil storage tank, and one of the one-way valves is arranged between the oil return pipe and the hydraulic oil storage tank. When an automobile collides with the others, no matter in front or lateral collision, the primary energy absorber deforms in the first time, hydraulic oil in the primary energy absorbers flows to the other primary energy absorbers and the second energy absorber, two-stage energy absorption can effectively reduce impact and damage caused by automobile collisions.
