Abstract:
The present invention relates to an shock absorber based on the cutting, inward-folding and crushing of composite tube, comprising a destructing cap, a flat-pressing cap, a cutter and a positioning tube. The cutter is positioned in the destructing cap, and has a lower end connected to an inner flange of the destructing cap and an upper end connected to the positioning tube. The positioning tube is positioned in the destructing cap and closely connected to the inner wall of the destructing cap, and has a lower surface in contact with the cutter. The destructing cap, the positioning tube and the composite tube are respectively provided with aligned pin holes, and bound together with a pin. Energy is absorbed through destruction generated due to cutting and inward-folding of the composition tube. Energy can also be absorbed through destruction generated due to the inward-folding of the composite tube, without using the cutter. Compared to existing technology, the device may be used as a structural component in a normal working state. In the colliding and crushing state, the device fully destructs the composite. The present invention has the following advantages: the energy-absorption ratio is high; and the energy absorbing device only bears an axial force in the process that the composite is being destroyed, does not bend or rupture, keeps the structure stable, and avoids spattering of scraps.

Claim (Index 2):
The shock absorber based on the cutting, inward-folding and crushing of composite tube according to  claim 1 , wherein the destructing cap comprises a lug, an inlet radius, a flange and a guide curved face;\n the inlet radius is positioned at the upper end of the destructing cap to guide the composite tube to be inserted into the destructing cap; the lug is positioned at the lower end of the destructing cap to be connected to an external structure; the flange is positioned in the destructing cap, and is directly connected to the cutter to fix the lower surface of the cutter; the guide curved face is positioned in the destructing cap, and when the composite tube is cut into strips by the cutter, the strips guided by the guide curved face move towards the inner cavity of the composite tube along the guide curved face.
