Abstract
The invention discloses a vehicle front wallboard with a strengthening structure, which comprises a front wallboard and the strengthening structure welded on the front wallboard. The strengthening structure is structured as a 'cross-shaped' sheet metal component by welding a middle strengthening beam, left and right strengthening beams and upper and lower strengthening parts; and the strengthening structure is soldered on the front wallboard and forms an enclosed cavity together with the front wallboard. The vehicle front wallboard has high strength and rigidity and high manufacturability.
Description
Technical field
The present invention relates to automobile component, particularly the front panel of automobile.
Background technology
Front wall board of automobile is as the vitals of separating passenger cabin and engine bin, many and the complex structure of its function, generally be that cold-rolling steel-plate punch by 0.8～1mm forms, because of its stiffness and strength a little less than, usually need the design additional strengthening to increase its strength and stiffness, improve the NVH of body in white simultaneously.At present, generally be the strength and stiffness of strengthening front panel at the horizontal brace panel of engine bin local welding and middle brace panel.Horizontal brace panel and middle brace panel adopt high tensile steel plate more, fit tightly the position a little less than front panel local strength, are connected with front panel by spot welding.Though this kind front panel structure is improved to some extent to its strength and stiffness, but still can not reach comparatively satisfied degree, and horizontal brace panel and middle brace panel adopt high tensile steel plate, increased the cost of front panel, and horizontal brace panel and middle brace panel need fit tightly with front panel, cause the anufacturability of front panel relatively poor.
Summary of the invention
The purpose of this invention is to provide a kind of front wall board of automobile, the strength and stiffness of front panel are improved largely, the manufacturing process of front panel is improved with additional strengthening.
Front wall board of automobile with additional strengthening of the present invention, comprise front panel and the additional strengthening that is welded on the front panel, the both sides of front panel are welded with the A-pillar reinforcement plate, its upper limb is welded with fan heater pressure chamber plate, described additional strengthening is by middle strength beam, left side strength beam, right strength beam, the sheet metal component structure that is " ten " word shape that last reinforcement and following reinforcement are welded, wherein, the left end welding of the right-hand member of left side strength beam and middle strength beam, the left end of right strength beam and the welding of the right-hand member of middle strength beam, welded with the middle part of middle strength beam respectively the upper end of reinforcement under the lower end of last reinforcement reached, and it is vertical with middle strength beam, middle strength beam, left side strength beam and right strength beam horizontal welding are on front panel, last reinforcement and following reinforcement vertically are welded on the front panel, all form near closed hollow ring with front panel, the left end of left side strength beam and the right-hand member of right strength beam weld with the A-pillar reinforcement plate respectively, the upper end of last reinforcement and fan heater pressure chamber plate welding.
The cross-sectional plane of middle strength beam, left and right strength beam and upper and lower reinforcement takes the shape of the letter U, and is provided with outside flange in its both sides, and middle strength beam, left and right strength beam and upper and lower reinforcement are by this flange and front panel welding.
Front wall board of automobile of the present invention, can make front panel strength and stiffness in the horizontal and vertical directions be strengthened, thereby improve front panel integral intensity and rigidity after it is welded on the front panel because its additional strengthening is " ten " word shape structure.Because middle strength beam, left and right strength beam and upper and lower reinforcement and front panel welding back form near closed hollow ring, it has good energy-absorbing effect, can improve the strength and stiffness of front panel largely, need not to adopt high tensile steel plate can reach effect preferably, thereby reduced the cost of front panel; Be connected and middle strength beam, left and right strength beam and the upper and lower reinforcement flange by its both sides carries out spot welding with front panel, make the convenient welding of additional strengthening and front panel easy, thereby the manufacturing process of front panel is improved.
