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,...

Abstract

The invention discloses an efficient progressive stable energy absorption device which comprises a bumper, an oil pressure energy absorption mechanism located on the rear side of the bumper, and an air pressure energy absorption mechanism located on the rear side of the bumper. The oil pressure energy absorption mechanism comprises an oil cylinder, a connecting piece, and an oil pressure piston plate movably arranged in the oil cylinder. The connecting piece is connected between the bumper and the oil pressure piston plate in a transmission mode, and an oil outlet is formed in one end of the oil cylinder. The oil pressure energy absorption mechanism further comprises a gland for opening and closing the oil outlet. The air pressure energy absorption mechanism comprises an air cylinder, and an air pressure piston plate movably arranged in the air cylinder. When the bumper is impacted, impact force is transmitted to the oil pressure piston plate through the connecting piece, the oil pressure piston plate extrudes oil in the oil cylinder and enables the oil to push the gland open to flow out of the oil outlet, and the oil applies pressure to the air pressure piston plate to enable the air pressure piston plate to compress air in the air cylinder. By means of the device, energy can be well absorbed, vibration reduction and cushioning are achieved, the impact force is reduced, stability is improved, and therefore a good protection effect is achieved for a driver and passengers.

Description

technical field [0001] The invention relates to a high-efficiency progressive stable energy-absorbing device, which belongs to the field of collision protection. Background technique [0002] With the continuous development of the automobile industry and the continuous improvement of people's living standards, the number of automobiles in my country is increasing, but the incidence of automobile traffic accidents is also increasing year by year. According to the statistics of the World Health Organization, about 1.3 million people die every year in the world. in road traffic accidents. The potential safety hazards of automobiles seriously affect people's personal and property safety. Therefore, people pay more and more attention to the collision safety of vehicles. How to develop high-performance, safe and reliable energy-absorbing devices has become an urgent and important topic for scientific researchers and automobile designers. [0003] For automobile energy-absorbing d...
