Morphology

beat + mine + brain

The verb 'beat' combined with 'brain' creates a metaphorical image of striking or straining the mind, so a learner who knows 'beat' and 'brain' can plausibly infer it means causing mental strain or trying very hard to think. However, the specific idiomatic phrasing is not fully literal or highly predictable and is less common than more standard expressions (e.g. 'rack my brains'), so some exposure is typically needed.

Etymology

The phrase beat my brain uses the picture of someone hitting their head to force out an idea: the words beat and brain give a strong image of hard, physical effort. That's why it means 'to think intensely' or 'to struggle to remember'.
