The wearable projection device 100 is detachably disposed in the receiving slot 210 of the docking station 200. In this embodiment, the wearing body 105 includes a positioning hole 190. The expansion base 200 includes a positioning post 250 located in the receiving groove 210 and corresponding to the positioning hole 190. The projection device 100 does not randomly shake in the accommodating groove 210 of the docking station 200.

In addition, the projection lens group 220 is located at a position corresponding to the micro-projection module 120, so that a projection image projected by the micro-projection module 120 can pass through the projection lens group 220, and the projection lens group 220 is an adjustment filter. Better imaging quality can be obtained by projecting the lens group 220.

The second port 240 is located beside the receiving slot 210 and corresponds to the position of the first port 180. When the wearable projection device 100 is disposed in the receiving slot 210 of the docking station 200, the first port 180 is electrically connected to the second port 240 to enable power or/or data transmission. The speaker 230 of the docking station 200 can play out the sound originally emitted by the audio player 150 of the wearable projection device 100. Since the bulk of the docking station 200 can accommodate a larger speaker 230, it can provide better. The sound quality effect.

The wearable projection device 100 of the present embodiment uses the wireless transmission module 130 to pair with a mobile phone or a computer and transmit signals through Bluetooth or WIFI. The wearable projection device 100 can be worn on the head to project a movie or a briefing on the mobile phone or the computer. In the process of projection, the combination of the audio player 150 and the micro-projection module 120 can be used for the user to experience the miniature. The feeling of the theater. During the use of the wearable projection device 100, the user's head may move. At this time, the infrared sensor 140 detects the amount of change in the distance between the projection surface and the head, and adjusts the distance and orientation of the imaging. The projected position remains in front of the line of sight. The wearable projection device 100 of the embodiment can also be used as a driving recorder. The camera module 160 can record the image in front, and then can watch the driving record through the way of projection or the connection of the mobile phone. In addition, the docking station 200 uses the projection lens group 220 (adjustment filter) to enhance the projection quality of the wearable projection device 100, and the wearable projection device can be achieved through the combination of the first port 180 and the second port 240. 100 charging effect.

In summary, the wearable projection device of the present invention has a micro-projection module disposed on the wearing body. When the user wears the wearing body, the user can project the image directly in front of the user, and the screen rotates with the user. By changing the position, the user does not have to adapt to the perspective of the picture. The wearable projection device can also be detachably disposed in the receiving slot of the docking station. When the wearable projector device is disposed in the receiving slot of the docking station, the projection lens group is located at a position corresponding to the micro-projection module. In order to enable the projection image projected by the micro-projection module to pass through the projection lens group, the projection quality is improved.
