The invention discloses an automobile parcel shelf cross beam structure which comprises a parcel shelf upper cross beam and a parcel shelf cross beam body, the parcel shelf upper cross beam is arranged on the parcel shelf cross beam body and connected with the parcel shelf cross beam body to form a transverse cavity structure, and the automobile parcel shelf cross beam structure further comprises a pair of parcel shelf cross beam partition plates and a pair of side wall parcel shelf supporting plates used for being fixed to a side wall framework. And the end part of a transverse cavity structure formed by the parcel shelf upper cross beam and the parcel shelf cross beam body is connected with the side wall parcel shelf supporting plate on the corresponding side through a parcel shelf cross beam partition plate. The parcel shelf cross beam left and right partition plates and the parcel shelf cross beam body are welded into an assembly, then the assembly is welded with the side wall parcel shelf left and right supporting plates to form a stable beam-shaped structure, and then the assembly is welded with the parcel shelf upper cross beam again to form a closed rectangular cavity structure; the closed rectangular cavity structure effectively improves the torsional mode, bending rigidity and other performance indexes.
本发明公开了一种汽车包裹架横梁结构,包括包裹架上横梁和包裹架横梁本体,所述包裹架上横梁设在包裹架横梁本体上并相连形成横向腔体结构,还包括一对包裹架横梁隔板和用于固定在侧围骨架上的一对侧围包裹架支撑板;包裹架上横梁和包裹架横梁本体形成的横向腔体结构端部通过包裹架横梁隔板与对应侧的侧围包裹架支撑板相连。包裹架横梁左右隔板与包裹架横梁本体焊接为总成,后与侧围包裹架左右支撑板焊接形成稳定的梁形结构,而后再次与包裹架上横梁焊接形成封闭的矩形腔体结构;封闭的矩形腔体结构有效提升其扭转模态以及弯曲刚度等性能指标。
