The beacon (and black box) was encapsulated in a hardened casing designed to survive a Mach 2 impact with the Martian surface (the article notes that parachute and retrorocket deployment were considered the riskiest components of the EDL). In the event of a crash, the black-box would return telemetry for the benefit of future missions, and perhaps a little scientific data as well so the Chinese could technically claim to have put a crasher probe on Mars for a few days (until the battery ran out).

Extensive testing was performed to develop the black-box, apparently involving firings out of some sort of cannon.
