Description
Technical field
This utility model relates to auto parts and components field, is specifically related to a kind of automobile B-column.
Background technology
Along with the development of automobile industry, automobile has become as the important vehicles that people's daily life is indispensable.And popularizing along with automobile, people are more and more higher to the requirement of automotive performance, while obtaining good dynamics and economy, it is also desirable to have the highest safety guarantee.In road traffic accident, the security performance of automobile itself is also very important factor.Vehicle safety performance is good, often can avoid the degree that injures and deaths occur or reduce of accident.
Automobile B-column, between Qianmen and back door, is important load-carrying member, except playing the effect of support, moreover it is possible to play the effect of doorframe.Front door to be ensured can be opened under bearing certain impact, simultaneously as the rigidity of B post has been largely fixed the integral rigidity of body structure, it is desirable to it must have higher strength and stiffness.Further, B post has directly impact for degree of injury and the roof rolling resistance to compression of occupant during automobile generation side collision, and B post can not be really up to the mark, can not be the softest.Because the meeting really up to the mark of B post makes energy be quickly transferred to occupant, it is impossible to make energy to be absorbed well by vehicle body and displacement wall；On the contrary, B post is crossed soft, it can be made to deform excessive, thus passenger causes bigger injury.
Current automobile B-column structure is complicated, is usually and is made up of B post outside plate, B post outside plate reinforcement version, B post inner panel reinforcing plate and B post inner panel, and, manufacturing process is loaded down with trivial details, and processing cost and die cost are higher.The most important thing is, designed B post strength and stiffness all do not reach requirement, and particularly when automobile generation side collision and automobile occur rolling ceiling to be impacted, roof of the vehicle and B post can occur gross distortion, cause the biggest injury to passenger.
Owing to automobile B-column is mainly used to support roof and front and back door, and when vehicle is by being clashed into from side, B post also can play the protective effect to occupant.Therefore, it is necessary to a kind of new automobile B post of exploitation, preferably improve strength and stiffness, while meeting side collision requirement, preferably support roof.
Summary of the invention
For solving above-mentioned technical problem, this utility model provides a kind of honeycomb interlayer automobile B-column, and described automobile B-column includes B post outside plate, honeycomb interlayer and B post inner panel；Described B post outside plate base is provided with the bedplate with base vertical, and two sides of B post outside plate are respectively equipped with the sidewall paneling vertical with two sides；Described B post inner panel base is provided with the bedplate with base vertical, two sides of B post inner panel are respectively equipped with the sidewall paneling vertical with two sides, after the bedplate of the bedplate of B post outside plate and sidewall paneling and B post inner panel and sidewall paneling are connected, the receiving chamber of B post outside plate and B post one upper end open of inner panel intermediate formation；Described honeycomb interlayer is arranged on the receiving intracavity in the middle of B post outside plate and B post inner panel.
In order to meet the intensity of automobile B-column, rigidity requirement, improving the security performance of side collision, described honeycomb sandwich construction is to be made up of a series of regular hexagon list rooms structure, and two room mouths in described regular hexagon list room are respectively facing B post outside plate and B post inner panel.
In order to when preventing vehicle generation side collision further, occupant comes to harm, improve the safety coefficient of side collision, described B post outside plate outer lower portion is provided with a boss along the length of outside plate, described boss is arc with one end of external contact, boss both sides become γ angle with B post outside plate, and described γ is more than 45 degree and less than 90 degree.When there is side impact, automobile B-column lower deformation amount is big, beneficially energy-absorbing, and top intrusion volume, intrusion speed are little with intrusion acceleration, effectively protect the safety of occupant.
Automobile B-column described in the utility model is in order to reduce B post weight, and described automobile B-column outside plate, honeycomb interlayer and B post inner panel is all made up of carbon fibre composite.Further, in order to enable described automobile B-column fixed with vehicle body, the bedplate outer surface on described B post inner panel and B post outside plate is provided with the groove of wave structure.
In vertical direction, the width of described B post inner panel, B post outside plate and honeycomb interlayer becomes narrow gradually automobile B-column described in the utility model from the bottom up.
Advantage of the present utility model and good effect be:
1. this utility model is by designing a kind of novel honeycomb interlayer automobile B-column, has higher strength and stiffness so that it is can play the effect being effectively improved Side-impact safety energy, especially improve the safety coefficient of side impact.
