This utility model discloses an automatic hydraulic double-wing door device for a rear equipment compartment, comprising a compartment body and an inner frame. The inner frame is located inside the compartment body, and two sets of hydraulic rods (A-type) are symmetrically arranged on the inner wall of the inner frame, with each A-type hydraulic rod being movably connected to the inner frame. Each A-type hydraulic rod has an A-type push arm installed at its output end. A wing door body is symmetrically arranged inside the compartment body on one side of the inner frame. Each wing door body has a hinge shaft at its end near the compartment body, and the wing door body is movably connected to the compartment body via the hinge shaft. Each A-type push arm has an A-type linkage shaft at its end near the wing door body, and the A-type push arm is movably connected to the wing door body via the A-type linkage shaft. This utility model not only achieves convenient linkage opening and closing of the wing door and parallel extension of the shelves from the compartment body, facilitating temporary placement of miscellaneous items and retrieval or placement of goods on the shelves, but also improves ease of use.
