Abstract
The utility model discloses a car bra and front shroud inner panel thereof one is listed as the spill sphere at front shroud inner panel body middle part along what front shroud inner panel body width direction set up side by side, and the front shroud inner panel part between each sphere forms a cavity with the front shroud planking, and the crooked energy -absorbing in upon impact front shroud inner panel middle part adopts this structure to be favorable to colliding the requirement of pedestrian's protection, along front shroud inner panel body edge setting " U " type strengthening rib and horizontal bar formula strengthening rib, and surround the spill sphere has promoted whole bending of car bra and torsional rigidity, has solved the not enough shake problem that leads to of aluminum alloy front shroud rigidity.
Description
Technical field
The utility model belongs to vehicle body plate product, is specifically related to a kind of car bra and front hood back head structure thereof.
Background technology
Car bra assembly is generally by outside plate and inner panel undercut is bonding forms, and car bra assembly comprises the parts such as front hood panel, front hood back head, front hood hinge assembly, front hood hinge reinforcement, front shroud lock pin assembly, front shroud heat insulating mattress assembly.Wherein in order to strengthen the integral rigidity of car bra, front hood back head design is particularly important, and convex tendon layout, thickness of slab etc. have considerable influence to the rigidity of car bra plate.Front hood back head design aspect not only requires gently, but also will ensure the requirement of enough rigidity, intensity and head-on crash, reduces the vibration & noise etc. in vehicle traveling process simultaneously.
Energy source of car consumption is saved in the application of aluminum alloy materials on automobile now, realizes the trend of low-carbon environment-friendly.Car bra adopts aluminum alloy materials, not only alleviates quality, and reasonably the performance of structure design to shroud upper panel also promotes to some extent.
As shown in Figure 5, existing aluminium alloy car front hood back head mainly adopts uniform distribution concave structure form, the bending and torsion insufficient rigidity of this kind of front hood back head structural entity, causes front shroud that shake and local deformation easily occur.
Summary of the invention
The purpose of this utility model is to provide a kind of car bra inner panel, makes it meet in collision performance situation, promotes rigidity and NVH performance, solves car bra shake and problem on deformation, alleviates car bra quality simultaneously, reach the requirement of low-carbon energy-saving weight-saving.
The purpose of this utility model is also to provide a kind of car bra, adopts above-mentioned car bra inner panel, solves automobile shake and problem on deformation, alleviates car bra quality simultaneously.
Car bra inner panel disclosed in the utility model, comprise the front hood back head body of aluminum alloy material, a row concave ball surfaces for being arranged side by side along front hood back head body width direction in the middle part of described front hood back head body, is provided with reverse little convex bottom described concave ball surfaces; Along headstock to tailstock direction, the front portion of described front hood back head body arranges " U " type reinforced rib, described " U " type reinforced rib extends the side edge thereof covering car bra inner panel body, arrange horizontal strip type reinforced rib after described front hood back head body, described " U " type reinforced rib and horizontal strip type reinforced rib surround described concave ball surfaces.
Further, round-corner transition between described little convex and concave ball surfaces.
The invention also discloses car bra, comprise the front hood back head body of aluminum alloy material and front hood panel, a row concave ball surfaces for being arranged side by side along front hood back head body width direction in the middle part of described front hood back head body, be reverse little convex bottom described concave ball surfaces, between described little convex and concave ball surfaces, fillet is excessive; Along headstock to tailstock direction, the front portion of described front hood back head body arranges " U " type reinforced rib, described " U " type reinforced rib extends the side edge thereof covering car bra inner panel body, arrange horizontal strip type reinforced rib after described front hood back head body, described " U " type reinforced rib and horizontal strip type reinforced rib surround described concave ball surfaces; Front hood back head body and front hood panel periphery fasten and seal, and the bottom of the little convex on described concave ball surfaces, " U " type reinforced rib and the bottom of horizontal strip type reinforced rib are by structure viscose glue and front hood panel adhesion.
Further, round-corner transition between described little convex and concave ball surfaces.
The utility model beneficial effect is: the row concave ball surfaces for being arranged side by side along front hood back head body width direction in the middle part of front hood back head body, front hood back head part between each sphere and front hood panel form a cavity, front hood back head middle bent energy-absorbing during collision, adopts this structure to be conducive to colliding the requirement of pedestrian protecting; " U " type reinforced rib and horizontal strip type reinforced rib are set along front hood back head body edges, and surround described concave ball surfaces, improve car bra integrally bending and torsional stiffness, solve the jitter problem that aluminum alloy front shroud insufficient rigidity causes.

Detailed description of the invention
As shown in Figures 1 to 4, car bra, comprises front hood back head body 2 and the front hood panel 1 of aluminum alloy material, and front hood back head body 2 fastens with front hood panel 1 periphery and seals;
A row concave ball surfaces 6 for being arranged side by side along front hood back head body width direction in the middle part of front hood back head body 2, it is reverse little convex 61 bottom concave ball surfaces 6, round-corner transition between little convex 61 and concave ball surfaces, little convex 61 is connected with front hood panel 1 by structure viscose glue 7; The concave ball surfaces 6 of one row is arranged in the middle part of front hood back head, and the front hood back head part between each sphere and front hood panel 1 form a cavity, front hood back head 2 middle bent energy-absorbing during collision, adopts this structure to be conducive to colliding the requirement of pedestrian protecting.
Along headstock to tailstock direction, the front portion of described front hood back head body 2 arranges " U " type reinforced rib 5, described " U " type reinforced rib 5 extends the side edge thereof covering car bra inner panel body 2, arrange horizontal strip type reinforced rib 3 after described front hood back head body 2, described " U " type reinforced rib 5 and horizontal strip type reinforced rib 3 surround described concave ball surfaces 6; The bottom of " U " type reinforced rib 5 and the bottom of horizontal strip type reinforced rib 3 are connected with front hood panel by structure viscose glue.This kind of reinforcing rib structure improves car bra integrally bending and torsional stiffness, solves the jitter problem that aluminum alloy front shroud insufficient rigidity causes.
