Abstract
The utility model discloses a B column structure of an SUV (sports utility vehicle). The B column structure comprises a B column outer plate and a B column inner plate which are welded together, a strengthening plate is arranged between the B column outer plate and the B column inner plate, and a cross section of the B column inner plate is shaped in a lidless 'U'. Preferably, the yield strength of the B column strengthening plate ranges from 900 to1000Mpa, the tensile strength of the same ranges from 1400 to 1500Mpa, and the thickness of the same ranges from 1.1 to 1.3mm. The B column strengthening plate can be made of a hot forming plate, and the B column inner plate adopts a section structure with high inertia moment and can be fixed with the B column outer plate in a normal spot welding manner. A B column has great resistance to impact deformation, so that when the sidewall of the B column is collided, only tiny invasion is generated by the B column, the requirement for protecting passengers in a passenger compartment is met; meanwhile, the number of B column strengthening plates in normal B column structures is reduced, the complexity of the B column structure is lowered, weight of the B column structure is lowered, and manufacturability of the B column is improved.
Description
Technical field
The utility model relates to a kind of B-pillar structure of vehicle, more precisely, relates to the B-pillar structure of a kind of SUV, relates in particular to a kind of B-pillar structure of light-weight design.
Background technology
Automotive safety, energy conservation and environmental protection have become the three big research tendencies in current automotive engineering field.A vehicle body that satisfies the high security designing requirement is wanted on the one hand and can be reduced occupant's suffered impact by the energy in the distortion absorption collision process; Guarantee less crew module's distortion by vehicle body on the other hand.In the side collision process, the B post plays important effect to the crash survivability of vehicle.The B post of prior art is general to be adopted in the inner mode that increases a plurality of brace panels or increase strut bar of B column reinforcement plate and improves the ability of B post opposing blastic deformation, causes a series of problems such as B-pillar structure complexity, weight increase, cost, application electrophoretic effects be not good.Present stage, how to design the weight-saving B post of shock resistance deformability, be the difficult problem in automotive engineering field always.
Summary of the invention
The utility model is in order to solve problems of the prior art, the B-pillar structure of a kind of SUV is provided, it is simple in structure, improved the structural strength of B post, improved the anti-bending strength of B post, from another angle with, when guaranteeing this B post higher-strength, simplified the inner quantity of strengthening version of B post, it is better to make the side of vehicle hit safety performance.
In order to realize above-mentioned purpose, the technical solution of the utility model is: the B-pillar structure of a kind of SUV, comprise B post outside plate, the B post inner panel of weld together, be provided with brace panel between described B post outside plate and the B post inner panel, the cross-sectional plane of described B post inner panel is " recessed " font of uncovered.
Preferably, the yield strength of described B column reinforcement plate is that 900-1000Mpa, tensile strength are 1400-1500Mpa, and its thickness is 1.1-1.3mm.
B column reinforcement plate of the present utility model can adopt the Heat forming plate to make, and B post inner panel adopts the cross section structure with high moment of inertia, can fix by the spot welding mode of routine with B post outside plate.This kind B post possesses the ability of high opposing blastic deformation, and in the side collision process, the B post only produces minimum intrusion amount, reaches the requirement of occupant in the protection crew module; This kind B post has reduced the quantity of the interior brace panel of B post of conventional B-pillar structure simultaneously, has simplified the complexity of B-pillar structure, has promoted the lightweight of B-pillar structure, has promoted the manufacturability of B post.
Description of drawings
Accompanying drawing 1 shows the section drawing of the utility model B-pillar structure.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
With reference to figure 1, the B-pillar structure of a kind of SUV of the present utility model comprises B post outside plate 2, the B post inner panel 1 of weld together being provided with brace panel 3 between described B post outside plate 2 and the B post inner panel 1, and the cross-sectional plane of described B post inner panel 1 is handstand
The shape structure also can be regarded " recessed " font that is handstand state and uncovered as.Make it have higher moment of inertia.When vehicle when carrying out Collision test, collision at first acts on forward and backward car door, when treating that forward and backward car door is deformed into center body pillar, the B post upwards is delivered to deep beam in B post upper ledge and the top cover with collision energy rapidly on the one hand, is delivered to sill strip and floor crossmember downwards; On the one hand because the cross section structure of B post inner panel 1 high moment of inertia makes center body pillar obtain the ability of higher opposing blastic deformation; Make the B post absorb crash energy with the distortion of minimum, guarantee minimum B post intrusion amount, chaufeur and the personal safety of occupant when side impact in the protection crew module.Owing to its higher non-deformability, can reduce the quantity of B column reinforcement plate 3 in the conventional B post, reach B post lightweight purpose, simplified the center body pillar structure, be easy to guarantee the precision of vehicle body.
B column reinforcement plate 3 of the present utility model can adopt high-intensity Heat forming plate to make, make it the resilience problem of cold forming process intensity can not occur, and the Heat forming plate adopts laser to cut edge, cut the hole, therefore, and the shape surface accuracy of B column reinforcement plate, position, hole precision, the more conventional cold forming process height of dimensional accuracy.
Preferably, the yield strength of described B column reinforcement plate is that 900-1000Mpa, tensile strength are 1400-1500Mpa, and its thickness is 1.1-1.3mm.
The utility model is by preferred embodiment having carried out detailed explanation.Yet, by to the studying carefully of preamble, to the variation of each embodiment with to increase also be that one of ordinary skill in the art institute is apparent.Being intended that all these variations and increasing of applicant all dropped in the scope that the utility model claim protects.
Similar numbering refers to similar element in the whole text.For the purpose of clear, the situation that some line, layer, element, parts or feature are amplified may be arranged in the accompanying drawings.
Term used herein is only for to be illustrated specific embodiment, and it is not to be intended to the utility model is limited.Unless otherwise defined, all terms used herein (comprising technical term and scientific terminology) are all identical with the utility model one of ordinary skill in the art's understanding.
