Specifically, the position sensor is a proximity sensor arranged at a position corresponding to the refraction module moving away, the controller controls the near-eye display optical machine to be closed when receiving a trigger signal of the proximity sensor, and the dual-purpose optical machine works; and when the trigger signal of the proximity sensor is not received, the controller controls the near-eye display optical machine and the dual-purpose optical machine to work. When the movable refraction module is not moved away, the proximity sensor is not triggered, and the controller controls the two optical machines 3 to work, namely the intelligent glasses operate in a near-to-eye display mode. And when mobilizable refraction module removed, the proximity sensor that corresponds the position of removing was triggered to send a signal to the controller, the controller received signal can judge that the refraction module removes, thereby control near-to-eye display ray apparatus and close, dual-purpose ray apparatus work, switches intelligent glasses to the projection mode. The proximity sensor's the position that sets up also can correspond the refraction module and do not remove, then the controller controls near-eye display ray apparatus and dual-purpose ray apparatus and all works when receiving proximity sensor's trigger signal, and controls near-eye display ray apparatus and close when not receiving proximity sensor's trigger signal, dual-purpose ray apparatus work. And the proximity sensor is adopted, so that the position condition of the movable refraction module can be accurately reflected.

That is, the first refraction module 51 and the second refraction module 52 are disposed corresponding to the optical engine 3, the first refraction module 51 is used as a movable refraction module, and when the first refraction module 51 is not removed, it is located between the optical engine 3 and the lens module 4, so that the light beam emitted from the optical engine 3 will be refracted due to the blockage of the first refraction module 51, and will not enter the lens module 4. When the lens module 4 is moved away, the light beam emitted from the optical engine 3 directly enters the lens module 4 and is projected out of the travel image through the lens. So set up, the overall arrangement of individual part and cooperation each other of being convenient for. In the case of using two optical machines 3, specifically, the first refraction module 51 and the second refraction module 52 may be disposed corresponding to one optical machine 3, and the third refraction module 53 and the fourth refraction module 54 may be disposed corresponding to the other optical machine 3, wherein the light beam emitted by the optical machine 3 is refracted by the third refraction module 53 and the fourth refraction module 54 in sequence and then projected onto the waveguide 6, and the third refraction module 53 and the fourth refraction module 54 are both fixedly disposed.
