Abstract

The invention discloses a backpack type projection apparatus. The apparatus comprises a backpack, the backpack is internally provided with a projector and at least one reflector, the front wall of the backpack is provided with a projection screen, the transverse extending direction of the reflector is consistent with the transverse extending direction of the projection screen, multiple support rods are inserted into the backpack, the extending direction of the support rods is consistent with the transverse extending direction of the reflector, the multiple support rods support the backpack, the two sides of the reflector are connected with the side wall of the backpack through a telescoping assembly, light emitted by the projector is projected on the projection screen after being reflected by the reflector, after the support rods are taken away from the backpack, the backpack is compressed towards the direction of the side wall, and the reflector is turned by 90 degrees to be parallel to the side wall. The backpack type projection apparatus has the following advantages: the projector, the reflector and the projection screen are integrated in one backpack, the volume occupied by projection equipment is reduced, and the carrying is facilitated; and when the projection equipment is not used, the backpack is compressed towards the direction of the side wall and the reflector is reversed by 90 degrees to be parallel to the side wall, such that the occupied space is smaller, and the carrying is more convenient.

Description

technical field [0001] The invention relates to a projection device, in particular to a backpack type projection device. Background technique [0002] A projection device is a device that can project images or video information onto a screen, and can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play corresponding video signals. The most traditional projection setups include a projector, a curtain and a table. When in use, the projector is placed on the table, and directly opposite the projector is a screen, and the image or video information of the projector is projected onto the screen for display. The farther the distance is, the larger the displayed image or video is. The disadvantage is that the projection equipment is too bulky and inconvenient to carry. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a foldable backpack-type projection device. After the ...
