Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

It is to be noted that, in the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the utility model.

Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Meanwhile, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "connected" and "connected" should be interpreted broadly, for example, as being fixedly connected, detachably connected, or integrally connected; the connection can be mechanical connection or electrical connection; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The first embodiment is as follows:

the utility model provides a portable projector, which comprises a housin 1, casing 1 comprises epitheca 11 and drain pan 12, epitheca 11 and drain pan 12 pass through the buckle and connect or pass through screw fixed connection, be equipped with mainboard 2 in the casing 11, the 11 upper surface of epitheca is equipped with first recess 13, keyboard 21 and touch area 22 set up in first recess 13, touch area 22 is located the lateral part of keyboard 21, keyboard 21 and touch area 22 are located same panel, keyboard 21 and touch area 22 are connected with main control board 2 electricity, can be with control command input to main control board through keyboard 21 and touch area 22.
