Embodiment Construction

[0024] The directions shown in the accompanying drawings are up, down, left, and right.

[0025] Such as Figure 1~2 , the shell 5 of the tension-compression energy-absorbing buffer device is axisymmetric, and is fastened by twelve bolts, and the fastening ring 4 is fastened to the end of the shell 5 . The cylindrical first energy-absorbing member 1 is installed at the leftmost end of the housing 5, along the direction of the center of the housing 5, followed by the conical second energy-absorbing member 2, and the tension and compression rod 3 is nested in the conical second energy-absorbing member. Component 2. Among them, the cylindrical first energy-absorbing member 1 and the conical second energy-absorbing member 2 are symmetrically installed in the housing 5, the cylindrical first energy-absorbing member 1, the conical second energy-absorbing member 2 and the tension and compression rod 3 coaxial line.

[0026] Such as image 3 , There are two oppositely connected ta...

Abstract

The invention discloses a tension-compression type energy absorption buffer device comprising first energy absorption components, second energy absorption components, a tension-compression rod and fastening rings. One fastening ring, one first energy absorption component, one second energy absorption component, the other second energy absorption component, the other first energy absorption component and the other fastening ring are sequentially arranged on the tension-compression rod, and the tension-compression rod is sleeved with the second energy absorption components. Each second energy absorption component is opposite to the adjacent second energy absorption component, and the sides, away from the second energy absorption components, of the first energy absorption components are connected with the fastening rings. The energy absorption buffering device can absorb energy in the stretching direction and can also absorb energy in the compression direction, and the buffering effect inthe stretching direction and the compression direction is achieved.

Description

technical field [0001] The invention relates to a buffer device, in particular to a tension-compression type energy-absorbing buffer device. Background technique [0002] Various energy absorbing devices are used to dissipate kinetic energy due to impact or other sudden force. Such energy absorbing devices typically use methods such as hysteresis of structural members, compression or extension of rubber, bending of springs, cold action of wires, or twisting of torsion bars; fluid friction, such as the flow of fluid through narrow orifices; Compression of gas, such as pneumatic shock absorbers; controlled fabric failure, such as tearing of stitches, etc. [0003] However, these devices and methods are generally not compatible with the simultaneous presence of tension or compression, extrusion energy absorption of metals. Additionally, these devices and methods are designed to absorb energy in only one direction (tension or compression). [0004] Accordingly, those skilled ...
