Background technique
With the fast development and continuous improvement of people's living standards of scientific and technological level, automobile has become people's trip must not
One of the vehicles that can lack.How while enjoying automobile belt to facilitate, the safety for improving automobile is also common concern
Topic.Bumper is one of safety guard for automobile.Bumper is generally by bumper skin, padded coaming and anticollision
Beam three parts composition.Anticollision beam action is to absorb impact force by the deformation of itself in the first time of collision, whole
A bumper shell system plays decisive role.
Last line of defense that collision prevention girders are collided as automobile, embodiment be vehicle passive security, then product
Strength character is the most important thing considered.Existing national requirements vehicle has better security performance, the requirement for anticollision
It correspondinglys increase.Naturally, the components performance requirement as formed automobile structure also increases, existing we mostly use BR1500HS
Material, i.e., high-strength weather-proof steel go production and processing collision prevention girders.Production and processing collision prevention girders are gone using high-intensitive steel, with original
The process of first aluminum alloy materials molding collision prevention girders is different.After aluminum alloy materials generally use high-temperature fusion, integration is squeezed into
Type, therefore complicated finished product can be made in aluminum alloy materials.But the fusing point of steel is very high, is squeezed into after can not melting
Type.Therefore the processing of steel is heat-treated again after whole timber is processed into profile, obtains finished product collision prevention girders.Molding mode is not
Together, us is caused in the collision prevention girders and the anticollision girder constructions of steel of design aluminium alloy to be also entirely different.
In view of this, the utility model designer deeply visits for the structural strength problem of steel formation problems, collision prevention girders
It begs for, develops the utility model, to improve problem of the prior art.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of novel collision protection beam section structures, for the anti-of steel
The section structure that beam designs is hit, realizes better structural strength, bigger protection width and more high-strength long-pending ratio.
Technical solution adopted by the utility model to solve the above technical problems is as follows: novel collision protection beam section structure, including
It is integrally formed the section in horizontal stud structure by steel, the section includes upper left end face, the left end being successively connected
Face, lower-left end face, interval face, upper right end face, right side and right lower end surface, the left side, interval face, right side are mutually flat
It goes and is vertically arranged, the right end of the upper left end face bends downward into weld part, and the upper weld part is fitted in interval
The left side in face is simultaneously welded with interval face, and the left end of the right lower end surface is folded upward at into lower weld part, the lower welding
Portion is fitted in the right side in interval face and welds with interval face.
The further preferred embodiment of the utility model: the section is closed figure structure, the upper left end face, a left side
End face, lower-left end face, interval face constitute a closed figure, the interval face, upper right end face, right side and right lower end surface structure
At another closed figure.
The further preferred embodiment of the utility model: the upper left end face and upper right end face is located at same level, institute
Arc-shaped transition between the upper weld part stated and upper left end face.
The further preferred embodiment of the utility model: the lower-left end face and right lower end surface is located at same level, institute
Arc-shaped transition between the lower weld part stated and right lower end surface.
The further preferred embodiment of the utility model: laser welding between the upper weld part and interval face, it is described
Laser welding between lower weld part and interval face.
The further preferred embodiment of the utility model: width and end face up and down direction on the section left and right directions
The ratio between height is 14:8.
The further preferred embodiment of the utility model: the upper left end face, left side, lower-left end face, interval face, upper right
End face, right side between lower end surface are arcwall face transition.
It compared with prior art, the utility model has the advantage of section is first integrally formed by steel, entire section
Structure is in horizontal stud structure.The utility model is completely enclosed end face structure, and structural strength is big.Using horizontal day
Character form structure is compared to buccal glyph shaped structure, while maintaining structural strength, has bigger protection width.Left upper end
The right end in face bends downward into weld part, and upper weld part is fitted in the left side in interval face and welds with interval face, bottom righthand side
The left end in face is folded upward at into lower weld part, and lower weld part is fitted in the right side in interval face and welds with interval face.Because this
Utility model uses steel, no equally direct melting extrusion of image of Buddha aluminum alloy materials.Steel can not form the collision prevention girders of no interface
Section, therefore how forming section and how designing welding position is the emphasis that the utility model considers.The utility model is logical
It is disconnected to form to cross the upper left end face being successively connected, left side, lower-left end face, interval face, upper right end face, right side and right lower end surface
Face.Upper left end face is bent to form weld part and interval face is welded, and right lower end surface is bent to form lower weld part and interval face is welded,
The structure for keeping entire section completely enclosed, effectively improves structural strength.And welding position is alternatively provided in section structure
Portion is located near interval face, does not influence structural strength.
