Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
As shown in Figures 1 to 4, the present invention includes longeron body 2, stringpiece reinforcement 6 and fastener, wherein,
The passage 4 for penetrating its both ends is provided with the longeron body 2, the longeron body 2 is along its length extremely
It is divided into adjacent rigid region 8 and crumple zones 10 less；
The stringpiece reinforcement 6 is inserted into the passage 4 of the rigid region 8 through extruding, and then is formed described in limitation
The frictional force of relative motion between stringpiece reinforcement 6 and the passage 4；
The fastener is used for being fixed for the stringpiece reinforcement 6 and longeron body 2.
As a further improvement on the present invention, the material of the stringpiece reinforcement 6 is aluminium alloy.
As a further improvement on the present invention, the cut-off body 12 set along its length is provided with the passage 4, it is described
The passage 4 is separated into first passage split 14 and second channel split 16 by cut-off body 12, and the stringpiece reinforcement 6 is provided with
At least two, it is press-fit into first passage split 14 and second channel body split 16 respectively by extruding.
As a further improvement on the present invention, the fastener is riveting parts.
As a further improvement on the present invention,
The fastener is rivet 18, and the rivet 18 includes cap body 20 and the body of rod 22, and the radial dimension of cap body 20 is big
In the radial dimension of the body of rod 22, the free end of the body of rod 22, which is additionally provided with, is radially divided into it two pieces of groove 24；
The rigid region 8 of the longeron body 2 is provided with some counter sinks 26, and the cap body 20 is inserted into the countersunk head
In hole 26, the counter sink 26 can limit the expansion of the radial direction of cap body 20；
A coordinating block 28 can be accommodated between the cut-off body 12 and the inwall of the longeron body 2 to insert, and can be along it
Slide axially；
The body of rod 22 can pass through the counter sink 26 and the through hole that is opened on the stringpiece reinforcement 6 with it is described
Coordinating block 28 contacts, when the body of rod 22 and the coordinating block 28 do opposing compression motion, the free end of the body of rod 22 to
Do extensional motion outside.
The concrete principle of the present invention is as follows：
The 1st, two stringpiece reinforcements 6 are inserted into the first passage split 14 of longeron body 2 respectively by way of extruding
In second channel split 16, now, extruding metal can obtain in deformed area forges more strong and uniform three-dimensional than rolling
Compressing stress state, therefore there is more preferable bonding strength；
