Vehicle-body energy absorbing device and method

Abstract

The invention discloses a vehicle-body energy absorbing device and method. The vehicle-body energy absorbing device and method aim at solving problems existing in the prior art, and a novel energy absorbing structure and a flowable flexible colloidal material are adopted. Energy is absorbed by changing the physical properties and state of the energy absorbing material, and the impact energy generated by collision is absorbed through flow resistance of colloid. The vehicle-body energy absorbing device is provided with a set of movable parts which are connected and can relatively slide and a sealing cavity, and the sealing cavity is filled with solid energy-absorbing colloid; the sealing cavity is communicated with a colloid recycling cavity through a plurality of flow discharge holes for the directional flow of the solid energy-absorbing colloid; when the solid energy-absorbing colloid is squeezed, the solid energy-absorbing colloid can flow from the sealing cavity to the recycling cavity through the flow discharge holes.

Description

technical field [0001] The invention relates to an energy-absorbing device for a vehicle, which is specifically designed to use a new energy-absorbing material and an energy-absorbing method, and belongs to the field of mechanical manufacturing. Background technique [0002] On all kinds of vehicles currently in use, in order to reduce the accidental collision of the vehicle, protect the safety of the occupants and avoid greater damage to the vehicle, an elastic energy absorbing device is usually installed on the coupler at the end of the vehicle. For example, a buffer block and an energy-absorbing block are connected to the rear end of the anti-climbing gear at the end of the anti-climbing device of the vehicle, so that the internal cavity of the buffer block can be used to transmit the energy generated by the accidental collision of the vehicle to the energy-absorbing block, so as to achieve the purpose of using the buffer block shell The extrusion deformation of the body ...

AI Technical Summary

Problems solved by technology

[0007] Therefore, the existing energy absorber structure mentioned above, due to the limited installation space and the limited size of the elastic energy absorbing device, its energy absorption value is relatively low, and it is difficult to meet the accidental impact of the vehicle for accidents with an impact speed of 8 km / h or more. when the energy absorption required by the

The car body itself will still be subject to a relatively large impact force, and there may even be a serious consequence of the compartments being piled up due to mutual bumping, which poses a greater threat to the personal safety of passengers
