Example Embodiment
[0025] Example one
[0026] Such as figure 2 with 3 As shown, an energy absorbing box for a vehicle provided by a preferred embodiment of the present invention includes a plurality of hollow shells 1 nested together, and two adjacent hollow shells 1 are connected by energy absorbing ribs 2. The number of layers of the hollow shell 1 and the number of energy-absorbing ribs 2 can be determined according to the energy absorption requirements of the developed vehicle model. In addition, the energy-absorbing ribs 2 are provided with a first deformation inducing groove 3 along the The hollow shell 1 extends in the radial direction. The energy-absorbing box of the present invention is provided with a plurality of nested hollow shells 1, and two adjacent hollow shells 1 are connected together by energy-absorbing ribs 2, so that the energy-absorbing box can be made into an integral piece with two sub-parts. The body part (two parts separated along the axis of symmetry) or the energy abs...

[0031] Example two
[0032] Such as Figure 4 As shown, the vehicle energy absorbing box of this embodiment is an improvement based on the first embodiment. The difference between the two is only that, in order to better guide the deformation of the energy absorbing box in the event of a collision, the hollow shell of this embodiment The body 1 is provided with a second deformation inducing groove 4, and the second deformation inducing groove 4 is annular and arranged along the circumferential direction of the hollow shell 1. Furthermore, the second deformation inducing grooves 4 are multiple distributed along the axial direction of the hollow shell 1.
[0033] The second deformation inducing groove 4 may be a square groove or an arc groove or a groove body of other shapes, which can be set according to specific conditions.
[0034] In order to ensure the strength of the hollow shell 1, the depth of the second deformation inducing groove 4 should not be greater than one third of the...
Example Embodiment
[0035] Example three
[0036] Such as Figure 5 As shown, the difference between the energy absorbing box for a vehicle of this embodiment and the first embodiment is that the hollow shell 1 of this embodiment is a hollow polyhedron, which can be a hollow tetrahedron, a hollow hexahedron, a hollow octahedron or other polygonal cross-sections. Hollow polyhedrons, this embodiment takes hollow tetrahedrons as an example. In addition, the plurality of hollow polyhedrons have the same structure and are nested in parallel with each other.
[0037] In this embodiment, there are several ways to connect two adjacent hollow polyhedrons through energy-absorbing ribs 2 as follows:
[0038] Such as Figure 5 with Image 6 As shown, the corner regions of two adjacent hollow polyhedrons are connected by energy-absorbing ribs 2. Specifically, one end of the energy-absorbing rib 2 is connected to the two connecting surfaces of the hollow shell 1, and the other end of the energy-absorbing rib 2 is co...
