Embodiment Construction

[0023] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0024] Such as figure 1 and figure 2 As shown, the present invention comprises a flat thin-walled tube 1 having a front side 2 receiving a positive impact load and a back side 4 opposite to the front side, one of the front side or the back side The middle part is punched with a "" type first groove 3, and the middle part of the other surface is punched with a "><" type second groove 5.

[0025] The thin-walled tubes are arranged according to the upper and lower layers, such as image 3 and Figure 4 As shown, the energy-absorbing device composed of thin-walled tubes has 5 layers, which are the first layer of thin-walled tubes 6, the second layer of thin-walled tubes 7, the third layer of thin-walled tubes 8, and the fourth layer of thin-walled tubes. wall tube 9 and the fifth layer of thin-walled tube 10 . The lower surface of the second groove of the t...

Abstract

The invention discloses a comprehensively self-locked thin-wall energy absorption pipe barrel which comprises a flat thin-wall pipe barrel body (1). The thin-wall pipe barrel body (1) is provided witha front face (2) receiving the forward impact load and a back face (4) opposite to the front face, a < >-shaped groove (3) is formed in the middle of one of the front face or the back face, and a > <-shaped second groove (5) is formed in the middle of the other face. The comprehensively self-locked thin-wall energy absorption pipe barrel has the advantages that comprehensive self locking can be achieved, the energy absorption rate is stable, and extension in the transverse direction, longitudinal direction and vertical direction can be achieved through the combination of the thin-wall energyabsorption pipe barrel.

Description

technical field [0001] The invention belongs to a thin-walled energy-absorbing device, which is applied to a series of protective systems requiring impact resistance and shock absorption, such as automobiles, train trains, airplanes and spacecraft. Background technique [0002] In real life, traffic accidents lead to more and more serious loss of life and property, and accidents such as collisions, impacts, and explosions in engineering also occur from time to time, and the direction of accidents such as collisions, impacts, and explosions is uncertain, which often leads to serious accidents. Consequences, so energy-absorbing protective system devices are required. Based on a large number of studies, it is generally believed that the ring-shaped thin-walled energy-absorbing structure has stable deformation, high specific energy consumption, stable bearing capacity, good energy absorption effect, small initial impact force, and is easy to replace. In the energy protection sy...
