Embodiment Construction

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0024] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations...

Abstract

The invention belongs to the technical field of passive safety protecting device and provides a honeycombed energy absorption device. The honeycombed energy absorption device comprises a shell, a honeycomb element and a guide pipe group. The shell is used for withstanding vehicle collision and filled with the honeycomb element for absorbing vehicle collision energy, and the guide pipe group is compressively and penetratingly arranged in the honeycomb element and used for guiding telescoping of the honeycomb element. By adoption of the compressible guide pipe group as a guide structure for thehoneycombed energy absorption device, when a vehicle is in front collision, the guide pipe group is shortened due to extrusion, and reserving a backward moving distance, equivalent to an initial length of the guide pipe group, on the rear side of the honeycombed energy absorption device is avoided, so that the technical problem of large occupied space of a backward moving stroke of the guide pipein the honeycombed energy absorption device in vehicle collision is effectively solved, capacity required by mounting of the honeycombed energy absorption device is reduced, and the vehicular internalspace utilization rate is increased.

Description

technical field [0001] The invention belongs to the technical field of passive safety protection devices, and more specifically relates to a honeycomb energy-absorbing device. Background technique [0002] At present, the installation of cellular energy-absorbing devices at both ends of the vehicle is regarded as one of the important measures for the passive safety protection of vehicles, especially rail vehicles. [0003] The traditional honeycomb energy-absorbing device generally uses a shell made of metal sheet to wrap the honeycomb structure to support and shape it; however, when the vehicle collides, the shell made of metal sheet is easy to withstand the impact Deformation occurs under the action of the honeycomb structure, causing damage to the internal honeycomb structure, causing the honeycomb structure to not be normally compressed in the direction of its longitudinal extension, and in order to guide the honeycomb structure to shrink and deform in the longitudinal d...
