Detailed Description
With reference to fig. 1-5, an installation positioning structure of an automobile front end module assembly is provided, in which an installation support 10 is provided on an automobile body framework a, a support installation surface a is provided on the installation support 10, the support installation surface a and a module installation surface b provided on a headlamp beam 20 of the front end module assembly are positioned and installed, the installation support 10 is slidably connected with the automobile body framework a, the sliding direction is consistent in the Z direction, a headlamp positioning hole is provided on a fender 40, and a tool is matched with the headlamp positioning hole for positioning. The front end module is positioned directly on the mounting support 10 and does not need to be guaranteed through a tool, the mounting support 10 guarantees Z-direction precision in a Z-direction sliding connection mode, therefore, Z-direction limiting mechanisms are reduced, tool structures are reduced, assembly difficulty is reduced, X/Y directions pass through headlamp positioning holes on the fender 40 to serve as front end module positioning holes, reference conversion and tolerance accumulation are reduced, and appearance perception quality of a front face sensitive area is guaranteed.
An X-direction positioning hole 31 and a Y-direction positioning hole 32 which are used for being matched with a tool for positioning are formed in a water tank cross beam 30 of the front-end module assembly, and a positioning pin 33 penetrates through the X-direction positioning hole 31/the Y-direction positioning hole 32 to position the front-end module assembly and the tool.
The mounting bracket 10 comprises a first mounting bracket 11 connected with a front mounting surface b1 at the front part of the headlamp beam 20 and a second mounting bracket 12 connected with a rear mounting surface b2 at the rear part of the headlamp beam 20, a mounting hole c is formed in a bracket mounting surface a, connecting holes d corresponding to the mounting hole c are formed in the front and rear mounting surfaces b1 and b2, and bolts penetrate through the mounting hole c and the connecting holes d to fixedly connect the headlamp beam 20 and the mounting bracket 10.
The first and second mounting supports 11 and 12 are identical in structure, the second mounting support 12 is integrally in a folded plate shape and comprises a flat plate and a vertical plate, a support mounting surface a and a mounting hole c are arranged on the flat plate, tightening holes e for being fixedly connected with an automobile body framework A are formed in the vertical plate, the vertical plate and the automobile body framework A are in sliding connection, and reinforcing ribs are arranged on the flat plate and the vertical plate.
