Abstract: A pair of projection glasses, a wearable projection apparatus, and a foldable optical engine are provided. The foldable optical engine includes a projection mechanism and a light emitting mechanism. A light input portion of the projection mechanism corresponds in position to a light output portion of the light emitting mechanism. The projection mechanism and the light emitting mechanism are pivotally connected to each other along a rotation axis so as to be rotatable relative to each other along the rotation axis. When the projection mechanism and the light emitting mechanism are rotated relative to each other to cause the light output portion to face toward the light input portion, the light emitting mechanism is configured to emit a light beam from the light output portion toward the light input portion, so as to allow the projection mechanism to receive the light beam for projecting an image light.

Abstract: A pair of projection glasses, a projection temple structure, and a modularized optical engine of a pair of projection glasses are provided. The pair of projection glasses includes a frame and a projection temple structure that is detachably fastened to the frame. The projection temple structure includes a temple and a modularized optical engine that is embedded in the temple. The modularized optical engine includes a light emitting mechanism, a projection mechanism spaced apart from the light emitting mechanism, and a connection mechanism that optically and electrically connects the light emitting mechanism and the projection mechanism. The connection mechanism is configured to transmit light and image signal from the light emitting mechanism to the projection mechanism, so that the projection mechanism can project an image light.
