Embodiment Construction
[0033] Please refer to figure 1 and figure 2 , Efficient progressive and stable energy-absorbing device, including bumper 1, a hydraulic energy-absorbing mechanism located at the rear side of the bumper, and a pneumatic energy-absorbing mechanism located at the rear side of the bumper.
[0034] The oil pressure energy-absorbing mechanism includes an oil cylinder body 14, a connector 6, and an oil pressure piston plate 9 that is movably arranged in the oil cylinder body. The connector 6 is transmission-connected between the bumper 1 and the oil pressure piston plate 9. For the oil outlet, the oil pressure energy-absorbing mechanism also includes a gland 11 for opening and closing the oil outlet.
[0035] The pneumatic energy-absorbing mechanism includes a cylinder block 17 and a pneumatic piston plate 16 movably arranged in the cylinder block.
[0036] When the bumper 1 is hit, the impact force is transmitted to the oil pressure piston plate 9 through the connecting piece 6,...
