US Patent 10939574 Server apparatus and tray mechanism thereof

A server apparatus includes a casing having an opening and a fixing structure away from the opening, a tray mechanism and a server module. The tray mechanism includes a tray, a transmission member slidably disposed on the tray and having a slot, a link having an engaging structure and being slidably disposed through the slot, and a handle movably connected to the transmission member and pivoted to the tray. The server module is disposed on the tray. When the tray is disposed in the casing and the handle pivots to a mounting position, the transmission member slides relative to the tray to drive the link to pivot, so as to rotate the engaging structure to be engaged with the fixing structure.
