The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Car front-upper assembly as shown in Figure 1 and Figure 7, for strip shape sheet metal component, comprise front upper member upper support 2 and front upper member lower support 4, the cross-sectional plane of front upper member upper support is Z-shaped, by plane of structure 2a on first, the first perpendicular wall 2b and first time plane of structure 2c form, the cross-sectional plane of front upper member lower support 4 is Z-shaped, by plane of structure 4a on second, the second perpendicular wall 4b and second time plane of structure 4c form, plane of structure 4a welding on plane of structure 2a and described second on described first, described first time plane of structure 2c and described second time plane of structure 4c welding, make to form between front upper member upper support 2 and front upper member lower support 4 the first cavity body structure 8 that cross-sectional plane is " mouth " font, this first cavity body structure 8 has improved integral rigidity and the intensity of car front-upper assembly greatly.Front upper member upper support 2 first on the left end of plane of structure 2a and right-hand member offer before upper member bracket mounting hole 1, car front-upper assembly is connected with two front upper member brackets 9 respectively by two front upper member bracket mounting holes 1.
