[0028] In order to make the automobile joint installation support have good crash strength, the arrangement positions of the first connecting beam 3 and the second connecting beam 4 in the first direction X are accurately set, so as to simplify the overall structure of the automobile joint installation support, and reduce the production cost while meeting the crash test strength. Therefore, in the first direction X, the distance from the center line of the first connecting beam in the second direction Y to the end portion close to the first cross beam 1 is L1, the interval between the center lines of the first connecting beam 3 and the second connecting beam 4 in the second direction Y is L2, the distance from the center line of the second connecting beam 4 in the second direction Y to the end portion close to the first cross beam 1 is L3, and L1:L2:L3=(1:5:5)-(3:7:7).
