Embodiment 1

[0017] Basic as attached figure 1 , figure 2 As shown: the portable projection device includes a micro-projector, a display screen 20, an extension plate 30, a block 31 and a flat mirror 32, wherein the micro-projector includes a micro-projector body 10 and a base 11, wherein the base 11 is in the shape of "∠", The angle between the horizontal section of the base 11 and the inclined section of the base 11 is an acute angle, the micro-projector body 10 is located inside the base 11, and the center of gravity of the micro-projector body 10 is close to the side of the horizontal section of the base 11 to ensure that the entire portable projection The lower center of gravity of the device ensures its stability. The display screen 20 is fixed on the inclined section of the base 11, the right end of the horizontal section of the base 11 has a chute, and the extension plate 30 is slidably arranged in the chute, and the bottom of the plane mirror 32 is hinged on the extension plate ...

Embodiment 2

[0019] The difference from Embodiment 1 is that a first through hole and a second through hole are opened on the side wall of the chute, and correspondingly, a first blind hole and a second blind hole are opened on the elongated plate 30, so as to adapt to the flat mirror 32. There are two states of folding and unfolding.

Abstract

The invention discloses a portable projection device, comprising micro projector, a display screen, an extension board, a stop dog and a plane mirror, wherein the micro projector comprises a micro projector body and a base, the base is in the shape of an inclined L, an included angle of a horizontal segment of the base and an inclined segment of the base is an acute angle, the micro projector body is located on the inner side of the base, the display screen is fixed on the inclined segment of the base, a chute is formed in a right end of the horizontal segment of the base, the extension board is arranged in the chute in a sliding manner, the bottom of the plane mirror is hinged on the extension board, the stop dog is arranged on the outer side of the hinging site of the bottom of the plane mirror and the extension board, and the top of the plane mirror can be propped against the back surface of the inclined segment of the base; and the portable projection device disclosed by the invention overcomes the problems that split projection display in the prior art always bring large necessary installation space, installation difficulty, carrying inconvenience and limited use occasions, and the like.

Description

technical field [0001] The present invention relates to a projection device, in particular to a portable projection device. Background technique [0002] In the field of graphics and image magnification display technology, projectors undoubtedly occupy a pivotal position. The projector and its display structure in the prior art are all independent and separated, that is, the display screen and the projector are two independent instruments, and a relatively large space is required to accommodate the display screen and the projector during installation and use, and the installation is also difficult. More labor-intensive and time-consuming. In today's society where efficiency is increasingly pursued, this projection display structure is powerless for some small-scale communication activities or other similar communication activities. Therefore, there is an urgent need for a projection display assembly that is easy to carry, simple in structure, small in size and capable of m...
