Head-mounted device and imaging projection module therefor

An image projection module mounted on a head-mounted device, the head-mounted device having goggles, and the image projection module comprising:

• a housing having a top wall, a bottom wall, a first side wall and a second side wall, and the top wall, the bottom wall, the first side wall and the second side wall are connected to each other to define a channel, a first channel opening and a second channel opening, wherein the channel is between the first channel opening and the second channel opening, and the first channel opening is adjacent to the opening;
• at least one connection element disposed on at least one of the top wall, the bottom wall, the first side wall and the second side wall, and configured to connect a frame of the goggles to fix the housing on the goggles;
• an optical element located on the channel and having a first optical surface and a second optical surface;
• a projector fixed on the housing and configured to project an image light beam toward the optical element, such that the image light beam passes through the first optical surface and the second optical surface sequentially;
• and
• a reflective element disposed in the housing and configured to receive the image light beam passing through the first optical surface and the second optical surface and reflect the received image light beam to generate a reflected light beam directed to the second optical surface, wherein the optical element is configured to refract the reflected light beam toward the lens to generate a refracted light beam, such that the refracted light beam leaves the channel from the first channel opening and passes through the lens for forming an image, wherein:
• the projector is fixed on the top wall,
• the reflective element is disposed on the bottom wall, and
• the channel is located between the projector and the reflective element.
