The present invention discloses a central cylinder for a saloon car, including a side wall outside plate and a central cylinder internal plate arranged on the side wall outside plate. The present invention is characterized in that the present invention also includes at least one reinforcing plate of the central cylinder arranged between the central cylinder internal plate and the side wall outside plate. The technical problem solved by the present invention is to provide a central cylinder of the saloon car to solve the safety problem for the side collision, of which the rigidity and the ability of bending and twisting resistance are reinforced.
Description
Technical field
The present invention relates to a kind of automobile center pillar, particularly a kind of car center pillar.
Background technology
At present, along with the speed of car is more and more higher, what bring is exactly the increase of unexpected probability of bumping thereupon, the very big threat of bringing for the personal safety of passenger in the car.The safety of automobile becomes the emphasis that the customer pays close attention to gradually.Along with the development of automotive electronic technology, such as belt with pre-load device, up-to-date technologys such as anti-locking braking system (car manufactures ABS), electronic stabilization device (ESP), safety air bag are applied on the automobile car manufactures with a series of.The four corners of China's urban highway is based on level crossing, show that according to statistics the incidence of automobile side impact traffic accident in 1998 accounts for 31.65% of whole traffic accident, serious number of injured people accounts for 30.15%, and these two indexs have all surpassed the corresponding data of head-on crash accident.Therefore, country has formulated and has implemented new side collision rules.
Domestic car industry is along with the appearance of corresponding side impact rules, and user's raising that the vehicle body safeguard construction is required, and it is the problem that presses for solution at present that vehicle body center pillar safeguard construction is provided.
Because the car center pillar is the supported cart top cover not only, the supporting power that also will bear forward and backward car door has also formed doorframe simultaneously.On center pillar, also to install some additional zero parts, as the safety strap of dress circle, and the electric wire wire harness.Existing car center pillar comprises center pillar inner panel and center pillar outside plate mostly, forms center pillar by welding.Car centre pillar cross-section shape is a more complicated, and difficulty of processing is big, complex process.And because existing car center pillar only adopts center pillar inner panel and side-wall outer-plate, so rigidity and the antitorque ability of bending resistance all can not satisfy the impulsive force that side collision brings.
Therefore, how to strengthen rigidity and the antitorque ability of bending resistance in the car centre-pillar structure, the problem that solves side face collision safety is the present technical issues that need to address.
Summary of the invention
The technical problem to be solved in the present invention is how to strengthen car center pillar rigidity and the antitorque ability of bending resistance, solves side face collision safety.
Specifically, a kind of car center pillar provided by the invention comprises side-wall outer-plate and is installed in center pillar inner panel on the described side-wall outer-plate, also comprises column reinforcement plate at least one; Column reinforcement plate is installed between center pillar inner panel and the side-wall outer-plate in described.
Column reinforcement plate is specially in first column reinforcement plate in the column reinforcement plate and second in described; Column reinforcement plate is installed on the side-wall outer-plate in described first; Column reinforcement plate is installed in described first on the column reinforcement plate in described second.
Column reinforcement plate adopts the phosphor-containing steel panel material in described.
Column reinforcement plate adopts the B250P1 material in described.
The column reinforcement plate cross-sectional plane is " n " shape or " several " font in described.
Described center pillar inner panel cross-sectional plane is " several " font.
Column reinforcement plate is " worker " font structure in described first.
Column reinforcement plate comprises first crossbeam, second crossbeam and the gusset that connects described first crossbeam and second crossbeam in described first.
The column reinforcement plate bottom width is greater than its upper width in described second.
The column reinforcement plate cross-sectional plane is " n " shape in described second, and described cross-sectional plane has two boss at least.
Compare with above-mentioned prior art, because car center pillar of the present invention, between center pillar inner panel and side-wall outer-plate, install column reinforcement plate at least one additional, so just strengthened car center pillar rigidity and the antitorque ability of bending resistance, solved the problem of side face collision safety to a certain extent.
