Portable projector

The present invention relates to a projection device, and more particularly to a portable projection device.

With the growing development of mobile phone technology, mobile phones have become an integral part of our lives. More and more mobile phones are integrated with rich features such as camera and projection. However, some portable projection devices such as mobile phones have a small projection angle and a large projection distance. Therefore, how to realize large-angle projection in a portable projector device and shorten the projection distance has become a problem that the industry needs to solve. .

In view of the above, it is necessary to provide a portable projection device having a large projection angle and a shortened projection distance.

A portable projection device includes a main body and a projection member. The main body defines a receiving slot, and the projection member is fixed in the receiving slot. The portable projector further includes a reflective assembly. The reflective assembly is rotatably coupled to the body. The reflective component is opposite the projection member for reflecting the projection of the projection member.

Compared to the prior art, the portable projection device is connected by a rotatable connection A reflective component on the body reflects a projection of the projection. Thereby, the projection distance is reduced, and the projection angle is enlarged.

In this embodiment, the rotating plate 21 includes a first surface 212 adjacent to the first body portion 122 and a second surface 214 opposite the first surface 212. An opening 213 extending through the first surface 212 and the second surface 214 is defined in the rotating plate 21, and the reflecting plate 22 is fixed in the opening 213. It can be understood that the rotating plate 21 may not directly open the opening 213, and the reflecting plate 22 may be directly fixed on the rotating plate 21. The free side of the rotating plate 21 corresponds to the position of the two card slots 1224 of the first main body portion 122, and two hooks 215 respectively matched with the card slots 1224 are respectively disposed. The hook 215 is made of an elastic material and can be integrally formed with the rotating plate 21. The hook 215 can be locked in the card slot 1224 to engage the rotating plate 21 with the upper cover 12 . A latching block 216 is respectively disposed at two ends of the rotating edge of the rotating plate 21. In the embodiment, the block 216 is integrally formed with the rotating plate 21 , and the block 216 defines a second receiving hole 2162 .

The rotating member 23 includes two springs 232 and two rotating shafts 234. The shaft 234 is matched with the two shaft holes 1226 of the first body portion 122. The spring 232 includes a first connecting portion 2321 and a second connecting portion 2322. In the embodiment, one end of the rotating shaft 234 has a stopper 2342 extending in the radial direction of the rotating shaft 234. In this embodiment, the sum of the longitudinal thicknesses of the stopper 2342 and the pressure plate 123 is equal to the longitudinal depth of the groove 1225.
