Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] A corrugated energy-absorbing structure, refer to Figures 1 to 8 , including a plurality of energy-absorbing columns 1, so that the entire energy-absorbing structure can have sufficient deformation and crushing space in the process of being crushed by a collision, and each energy-absorbing column 1 adopts the same height h to ensure Most of the energy-absorbing columns 1 can produce energy-absorbing effects at the same time. The energy-absorbing column 1 is formed by splicing two corrugated units 11; the corrugated unit 11 is formed by splicing two corrugated sheets 111; Including straight lines arranged on the upper and lower sides; between the two straight sides is a corrugated curved surface, the side view of the curved surface is a curve, and the curve satisfies

Abstract

The invention provides a corrugated energy absorption structure which comprises a plurality of energy absorption columns, and each energy absorption column is formed by splicing a plurality of corrugated units pairwise. Each corrugated unit is formed by splicing two corrugated sheets; An angle is formed between the two corrugated sheets, and each corrugated sheet comprises straight line edges arranged on the upper side and the lower side; a corrugated curved surface is arranged between the two straight line edges, and the side view of the curved surface is a curve. By means of the technical scheme, the energy absorption structure can have high energy absorption capacity in the collision process.

Description

technical field [0001] The invention relates to the field of energy absorption, in particular to a corrugated energy absorption structure. Background technique [0002] In recent years, with the rapid development of the transportation industry, the density of urban networks and logistics networks and the speed of transportation are rapidly increasing. This has brought great challenges to the safety of personnel and objects. In the face of complex and high-speed conditions, the protective structure needs sufficient cushioning and energy absorption performance to protect the safety of occupants and objects. However, the current structures often have high cushioning capacity and low initial stiffness but are not ideal in terms of energy absorption, or are capable of absorbing energy during a collision but have high stiffness, resulting in a large overload at the moment of collision, and there is little protection. The structure can take into account the characteristics of both...
