Embodiment

[0034] In this embodiment, the aluminum alloy material is used to make a porous imitation butterfly wing structural part (as the first energy-absorbing unit), a porous imitation flower beetle elytra structural part (as the second energy-absorbing unit) and a hollow cylinder (as the energy-absorbing unit). box body), wherein, the porous imitation butterfly wing structure (as the first energy-absorbing unit) and the porous imitation flower beetle elytra structure (as the second energy-absorbing unit) can be imitated flower beetle elytra structure and the imitation flower beetle elytra structure by the industrial 3D printer The imitation butterfly wing structure is printed in one piece. The butterfly-like wing structure and the beetle-like elytra structure are interpenetrated and connected by aluminum alloy circular panels to form an energy-absorbing unit, and multiple energy-absorbing units are filled in the hollow cylinder to form a core energy-absorbing unit.

Abstract

The invention discloses an efficient, stable and collision-resistant automobile energy absorption box. The efficient, stable and collision-resistant automobile energy absorption box comprises an energy absorption box body, a plurality of energy absorption units and flat plates, wherein the energy absorption box body is filled with the energy absorption units, and the flat plates are arranged between every two adjacent energy absorption units; the energy absorption unit comprises a first energy absorption unit and a second energy absorption unit; the first energy absorption unit is of a spiral structure with multiple holes, the second energy absorption unit comprises a plurality of transverse cylinders arranged transversely and a plurality of longitudinal cylinders arranged longitudinally, and the transverse cylinders and the longitudinal cylinders are correspondingly filled in the holes of the first energy absorption unit in an orthogonal layering mode to form the energy absorption unit. The first energy absorption units generate large deformation to diffuse impact energy when bearing pressure, the second energy absorption units can bear axial and radial pressure at the same time, and the energy absorption box is prevented from being damaged when impacted at different angles.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to an efficient, stable and collision-resistant automobile energy-absorbing box. Background technique [0002] The car may collide with other vehicles at different angles and with different impact forces during driving. In order to protect the safety of the driver and body personnel, it is necessary to install a suitable energy-absorbing box to have enough shock absorption when the vehicle is subjected to a large impact force. energy and relatively stable deformation. [0003] ZL201922120071.6 discloses an automobile energy-absorbing box. Its core structure has a double-layer imitation honeycomb hexagon, which has high toughness and can resist a large impact force. Wrinkles deform greatly, cannot transmit stress uniformly, and have low stability, so there is still a large amount of energy transmitted to the car longitudinal beam after collapse. In addition, this ho...
