Referring to Fig. 1, existing illustrate honeycomb energy-absorbing device provided by the invention.The honeycomb energy-absorbing device 1 includes shell
Body 11, honeycomb element 12 and guide pipe group 13, wherein, housing 11 is wrapped in the periphery of honeycomb element 12, for resisting vehicle
Shock, honeycomb element 12 is filled in housing 11, and for absorbing energy caused by Vehicular impact, guide pipe group 13 is compressible
It is threaded through in honeycomb element 12, for honeycomb element 12 to be guided to collapse, i.e., when vehicle collides, honeycomb element 12 can be along guiding
The direction that pipe group 13 extends collapses.It is appreciated that：Multiple pipes that honeycomb element 12 is extended by the axis along guide pipe group 13
The metal column of shape is welded to form, and the cross sectional shape of the metal column is preferably hexagon or circle, certainly, as the case may be and is needed
It asks, in other embodiments of the invention, the cross sectional shape of the metal column can be also other shapes, not limit uniquely herein.
Honeycomb energy-absorbing device 1 provided by the invention, compared with prior art, advantageous effect is：It employs and can be compressed
Guide frame of the guide pipe group 13 as honeycomb energy-absorbing device 1, when head-on crash occurs for vehicle, the length of guide pipe group 13
Shorten when being extruded, be equivalent to without being reserved in the rear side of honeycomb energy-absorbing device 1 retrogressing of 13 initial length of guide pipe group away from
From when colliding so as to efficiently solve vehicle, the backward travel occupied space of guide pipe is big in honeycomb energy-absorbing device
Technical problem reduces the volume needed for installation honeycomb energy-absorbing device, improves the utilization rate of inner space.
Further, referring to Fig. 2, a kind of specific embodiment as honeycomb energy-absorbing device provided by the invention, on
It states guide pipe group 13 and includes the first guide pipe 131 and the second guide pipe 132, wherein, the first guide pipe 131 and the second guide pipe
132 sockets.Specifically, the first guide pipe 131 can be retracted under the effect of external force in the second guide pipe 132, the second guide pipe 132
Length be greater than or equal to the first guide pipe 131 length.When head-on crash occurs for vehicle, the first guide pipe 131 is impacting
It is gradually retracted under the action of power in the second guide pipe 132, until the first guide pipe 131 is fully retracted in the second guide pipe 132, this
When, if above-mentioned honeycomb element 12 can not still fully absorb energy caused by collision, the second guide pipe 132 is in the work of impact force
Vehicle interior is gradually retracted under, until energy caused by collision is absorbed completely, it is seen then that need to only reserve the inside the vehicle
The space that two guide pipes 132 retreat.In this way, two level guide pipe had not only played the guiding role to honeycomb element 12, but also can be effectively
Reduce the distance that guide pipe retreats.
Further, referring to Fig. 2, a kind of specific embodiment as honeycomb energy-absorbing device provided by the invention, on
It states guide pipe group 13 and further includes pin 130, which is threaded through above-mentioned first guide pipe 131 and above-mentioned second guide pipe 132
On.Specifically, the first mounting hole (not shown) is offered on the tube wall of the first guide pipe 131, meanwhile, in the second guide pipe
The second mounting hole (not shown) is offered on 132 tube wall, the first guide pipe 131 passes through the first peace by one end of pin 130
Dress hole and the second mounting hole are clamped, herein, 130 and first mounting hole of pin and the second mounting hole interference with the second guide pipe 132
Cooperation.In this way, when the impact force being only applied on the first guide pipe 131 is more than the shearing force that pin 130 can bear, first
Guide pipe 131 can be just retracted towards the inside of the second guide pipe 132, so as to improve the ability that honeycomb energy-absorbing device 1 resists collision,
And if impact force is insufficient to allow guide pipe group 13 to deform, after being subjected to collision, pin 130 is only needed to change, is convenient for
The repair of guide pipe group 13 improves the maintenance efficiency of honeycomb energy-absorbing device 1, and the dimension for reducing honeycomb energy-absorbing device 1 forms this.
Further, it is oriented to as a kind of specific embodiment of honeycomb energy-absorbing device provided by the invention, above-mentioned second
