The invention relates to the field of automobile seat detection, in particular to an automobile seat back side wing extrusion endurance test device comprising a mechanical arm and a side wing endurance test device; the mechanical arm comprises a positioning seat, a rotating base, a first rotating arm, a second rotating arm and a third rotating arm; and the side wing endurance test device comprisesa mounting block and a wiping plate. When an extrusion endurance test is carried out on the side wings of the seat, the stroke and the rotating angle of the rotary base, the first rotating arm, the second rotating arm and the third rotating arm on the mechanical arm can be freely set, the third rotating arm is capable of driving the mounting block to move and pushing the wiping plate and a wipingsleeve to move, so that the side wings of the seat are wiped, the strength and the wiping speed required for wiping can be controlled, and then the abrasion-resistant degree data can be obtained after being wiped for a plurality of times, the manual work is replaced by mechanical automatic tests, the efficiency is accelerated, the pressing force is controllable, the wiping speed is controllable,and the test is more accurate.
