The invention discloses a parking device with double parallel four-bar linkages. The parking device includes two parallel four-bar linkages arranged side by side. Each parallel four-bar linkage includes a left side movement mechanism, a right side movement mechanism and a parking frame. The left side movement mechanism and the right side movement mechanism are in bilateral symmetry with respect tothe parking frame. The right side movement mechanism includes a second driven rod and a second driving rod. The second driven rod and the lower end of the second driving rod are hinged to the front end and the rear end of the right side of a bottom supporting frame respectively, the upper portion of the second driven rod is slidably connected with a second sliding connecting rod, the upper end ofthe second driven rod is hinged to the parking frame, the upper portion of the second driving rod is slidably connected with a fourth sliding connecting rod, and the upper end of the fourth sliding connecting rod is slidably connected with the rear end of the parking frame. Hydraulic cylinders are disposed between the second driven rod and the second sliding connecting rod and between the seconddriving rod and the fourth sliding connecting rod. The second driving rod is provided with a swing driving device, so that a vehicle is moved into a green belt from the road surface, thereby saving aspace on the road surface.
