The invention discloses an intelligent ring. The intelligent ring comprises a ring main body, and further comprises a ring bracket which is worn on a finger; the ring bracket is connected to the ringbracket; the ring main body comprises a PCB (Printed Circuit Board) module and a plurality of functional parts which are in signal connection to the PCB module; the PCB module is in signal connectionwith a mode switching assembly; and the PCB module can be used for switching a working mode according to a signal of the mode switching assembly so as to correspondingly control the opening and closing of each functional part. The intelligent ring disclosed by the invention can be worn on the finger; compared with an intelligent wristband which is worn on a wrist in the prior art, the intelligentring can be taken off when the intelligent ring is directly picked off along the finger, and is convenient to take off; meanwhile, the mode switching assembly is arranged and the PCB module can be used for switching the working mode to correspondingly control a opening and closing condition of each functional part; and a condition that each functional part is at a starting state all the time whenbeing not used can be avoided and energy sources are easy to save, so that the utilization cost can be reduced.
