For overcoming the problem of the vehicle resonance that collision prevention girders causes in the prior art, the utility model provides a kind of anticollision beam assembly, and it can eliminate the vehicle resonance problem that collision prevention girders causes under the precursor of proof strength.
The disclosed anticollision beam assembly of the utility model comprises collision prevention girders body, energy-absorbing box and mounting base; Said energy-absorbing box is arranged on the collision prevention girders body and with mounting base captives joint, and has to be used for and body shell bonded assembly mounting hole the distribution that assumes diamond in shape of said mounting hole in the vertical direction on the said mounting base.
In the utility model, above-mentioned in the vertical direction assumes diamond in shape to distribute and refers to that orthogonal two diagonal lines of this rhombus lay respectively on vertical direction and the horizontal direction.
Further, the outline of said mounting base becomes hexagon.
According to the utility model; Under the mounting hole in the vertical direction assumes diamond in shape the precursor that distributes; Further can mounting base be designed to hexagon (being that mounting base edge in the vertical direction surrounds rhombus), can reduce the volume of mounting base thus, thereby reduce total weight.
Further, offer lightening hole on the said collision prevention girders body.
Further, said energy-absorbing box has two, is arranged at two ends of collision prevention girders body respectively.
Further, said collision prevention girders body is outstanding arc on the direction away from mounting base.
Simultaneously, the invention also discloses a kind of automobile, comprise body shell and be fixed in the anticollision beam assembly on the body shell, said anticollision beam assembly comprises collision prevention girders body, energy-absorbing box and mounting base; Said energy-absorbing box is arranged on the collision prevention girders body and with mounting base captives joint; Said mounting base is captiveed joint with body shell, the distribution that assumes diamond in shape of the point of connection in the vertical direction of said mounting base and body shell.
To above-mentioned automobile, further, said mounting base is welded on the body shell, and said point of connection is a solder joint.
Perhaps, have mounting hole on the said mounting base, mounting base and body shell are through the mounting hole bolted connection.At this moment, the residing position of mounting hole is point of connection.
Further, the outline of said mounting base becomes hexagon.The concrete structure of mounting base repeats no more at this as previously mentioned.
Further, offer lightening hole on the said collision prevention girders body.
The point of connection of anticollision beam assembly and body shell is arranged to the in the vertical direction distribution that assumes diamond in shape; Be that anticollision beam assembly is when being installed on the body shell; The distribution that assumes diamond in shape of the stress point in the vertical direction of mounting base and body shell can guarantee the constant intensity of anticollision beam assembly on body shell, simultaneously; Can the vehicle resonance problem that collision prevention girders causes be eliminated in stable being fixed on the body shell of anticollision beam assembly.
To the disclosed anticollision beam assembly of the utility model, the mounting hole that assumes diamond in shape on the vertical direction and distribute is being set on the mounting base.When being fixed in anticollision beam assembly on the body shell, can eliminate the vehicle resonance problem that collision prevention girders causes through above-mentioned mounting hole.
