Description
Technical field
The invention belongs to packing technique on passenger vehicle body, be specifically related to top cap rear cross beam and the gusset lap-joint structure of two-box automobile, and the welding manner of top cap rear cross beam, top cover outside plate and gusset.
Background technology
Two-box automobile lacks rear separator for container and dividing plate crossbeam, and vehicle body lateral stiffness weakens.Therefore, the structure design of the roof panel cross member of two-box automobile and roof panel cross member and gusset lap-joint just seems particularly important.Because this region is positioned at corner, general top cap rear cross beam and gusset bridging arrangement complexity, the profile of connecting panel difficult with and the fine laminating in gusset rear portion, part locate also difficult in frock, and because multiple parts on the corner overlap, thereby easily cause scrap (bridge) to interfere, buckling deformation, causes tail-gate adhesive tape card not tight, the body torsional rigdity being therefore difficult to concerning two-box automobile and anti-side impact performance, with often joining badly because of part overlap joint, affect the presentation quality of car vehicle body.
Summary of the invention
The object of this invention is to provide a kind of two-box automobile top cap rear cross beam and gusset bridging arrangement, gusset back prop upper reinforcing plate and top cap rear cross beam top backdoor hinge brace panel are linked together, to address the above problem.
Technical scheme of the present invention is: it comprises top cap rear cross beam, side-wall outer-plate, fair water piece, back prop back veneer gusset, back prop upper reinforcing plate and top cover outside plate, it is characterized in that described top cap rear cross beam top is welded with backdoor hinge brace panel, backdoor hinge brace panel and back prop upper reinforcing plate and fair water piece are welded together, gusset back prop back veneer gusset and top cap rear cross beam are welded together, and top cover outside plate and side-wall outer-plate are welded together.Realize two-box automobile also has good body performance, this structure to guarantee welding process and the leak tightness of the each part of top cap rear cross beam and gusset lap-joint separator for container and dividing plate crossbeam in the situation that after lacking simultaneously.
Further, the described symmetrical distribution in backdoor hinge brace panel two ends on top cap rear cross beam, section is zigzag, is distributed with reinforced rib.
Further, described top cap rear cross beam section is arc line shaped, and back edge is low, and for overlapping roof drip bottom surface after top cover, front, along high, for supporting top cover outside plate, and is furnished with reinforced rib.
Further, the described horizontal section form of back prop back veneer gusset is arc line shaped, matches, and be designed with corresponding welding process via hole with top cap rear cross beam.
Further, upwards extend at described back prop upper reinforcing plate top, approximate concordant with back prop back veneer gusset, slightly shrinks, and section is zigzag, coordinates welding with backdoor hinge brace panel, and top is designed with welding process via hole in relevant position.
The present invention is simple and reasonable, by back prop upper reinforcing plate top rear is upwards extended, overlap with backdoor hinge brace panel, increase the structural strength of top cap rear cross beam and gusset lap-joint, feasible process, intensity is high, and cost is low, the torsional stiffness and the anti-side impact performance that have improved two-box automobile vehicle body, have good economy.
