Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the utility model can
To be combined with each other.
The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
Embodiment one
The present embodiment is related to a kind of back buffer beam, which includes the anticollision made of polyurethane glass fiber composite material
Beam ontology, and as shown in Fig. 1 combinations Fig. 2, which is in specifically strip, and its section is also configured as " mouth " font,
And the collision prevention girders connecting portion connected with vehicle frame is separately provided at its both ends.
In the present embodiment, which can be molded by pultrude process, specifically during manufacture, based on volume proportion, be gathered
Polyurethane 18%, glass 82% are preferably in a proportion of between urethane and glass, and the wall thickness of collision prevention girders ontology 1 is then set as 2.5
~3.5mm, and it can be preferably 3mm.And it is the edges and corners stress mistake avoided because of the collision prevention girders ontology 1 of " mouth " character form structure
Greatly, lead to occur deformation in pultrusion process, four edges and corners of 1 lateral surface of collision prevention girders ontology of the present embodiment also equal rounded corner
Setting, and the radius of fillet R is set as 25~35mm, preferably 30mm.
To adapt to automobile monnolithic case needs, the middle part of the collision prevention girders ontology 1 of the present embodiment is also configured as to one side
It rides out, so that collision prevention girders ontology 1 is shown generally as domes.When being physically connected on body of a motor car, the anticollision
The middle part of beam ontology 1 is specially to be rided out to tailstock direction.It is aforementioned to be located at collision prevention girders as a kind of alternative construction in the present embodiment
The collision prevention girders connecting portion at 1 both ends of ontology concretely crosses the connecting hole 2 of the arrangement of collision prevention girders ontology 1, using connecting hole 2, knot
Structure is simple, and convenient for molding, and is that can pass through the bolt realization being threaded through in connecting hole 2 and vehicle in the practical connection of back buffer beam
Frame is fixedly connected.
It, as shown in Figure 3, can be in anticollision in the present embodiment as another alternative construction in addition to connecting hole 2 as above
Through the slot 11 of side end face arrangement, which is specially along collision prevention girders sheet for setting on one side end face of 1 end of beam ontology
The length direction setting of body 1, and slot 11 is also opened on the end of collision prevention girders ontology 1.In addition, it should also be noted that, anticollision
Beam ontology 1 set the slot 11 end face also should be collision prevention girders ontology 1 close to vehicle frame side, for being connected with vehicle frame in
Side end face.
