As shown in FIG. 1 and FIG. 2 , the portable device 1 provided by the embodiment of the present invention includes a side wall 100 , a connecting portion 12 , a rotating portion 14 , and a pico projector 16 .

The portable device 1 may be an electronic device that needs to use a projection function, such as a desktop computer, a notebook computer, a display, a mobile communication terminal, or a personal digital assistant. The side wall 100 of the portable device 1 is provided with a recess 101 extending to the inside of the portable device 1. The groove 101 is for accommodating the connecting portion 12, the rotating portion 14, and the pico projector 16. The groove 101 includes parallel first inner surfaces 101a, second inner surfaces 101b, and a third inner surface 101c perpendicularly intersecting the first inner surface 101a and the second inner surface 101b, respectively. The two sides of the third inner surface 101c intersecting the first inner surface 101a and the second inner surface 101b are respectively provided with slide rails 102 parallel to each other. The slide rail 102 extends from the bottom of the groove 101 to the opening of the groove 101.

The connecting portion 12 includes a first connecting rod 120 and a second connecting rod 122. The opposite ends of the first connecting rod 120 are respectively provided with pulleys 1200. The pulleys 1200 are respectively received in the slide rails 102 on the third inner surface 101c. The first connecting rod 120 borrows The pulley 101 is slidably received in the recess 101 by pulleys 1200 disposed at both ends. A motor (not shown) is disposed in the first connecting rod 120 to drive the pulley 1200 to slide along the sliding rail 102. The second connecting rod 122 includes a first connecting end 122a and a second connecting end 122b. The second connecting rod 122 is vertically connected to the middle of the first connecting rod 120 by a first connecting end 122a thereof. The second connecting rod 122 is rotatably connected to the rotating portion 14 by a second connecting end 122b thereof.

The rotating portion 14 includes a base 140 and two support arms 142. The base 140 is an elongated rod body. The base 140 is rotatably connected to the second connecting end 122b of the second connecting rod 122 by a middle portion thereof. The two support arms 142 are respectively formed by vertically extending opposite ends of the base 140. An inner side of the two supporting arms 142 opposite to each other extends perpendicularly to a rotating shaft 1420.

The pico projector 16 includes two side faces 160 that are opposite to each other, and the side faces 160 are respectively formed with blind holes 162 at positions corresponding to each other. The pico projector 16 is rotatably coupled to the rotating shaft 1420 of the support arm 142 by the blind hole 162.

When the pico projector 16 is in an inoperative state, the first connecting rod 120 slides along the sliding rail 102 to the bottom of the groove 101. The connecting portion 12, the rotating portion 14, and the pico projector 16 are housed in the recess 101.

Referring to FIG. 3 together, when the pico projector 16 is required to be used, the motor in the first connecting rod 120 drives the pulley 1200 to slide along the sliding rail 102 to rotate the rotating portion 14 and the micro The projector 16 projects out of the recess 101. Rotating the pico projector 16 to align the projection lens with a projection screen, such as a whiteboard or a white wall, rotating the rotating portion 14 about the axis of the second connecting rod 122 to adjust the projection of the pico projector 16. angle.

It can be understood that the rotational friction between the second connecting rod 122 and the rotating portion 14 acts on the second connecting rod 122 to be greater than the gravity of the rotating portion 14 and the pico projector 16 acting on the second connection. The moment on the rod 122, the moment of the rotational friction between the pico projector 16 and the support arm 142 acting on the rotating shaft 1420 is greater than the moment acting on the rotating shaft 1420 by the gravity of the pico projector 16 to prevent The rotating portion 14 and the pico projector 16 are arbitrarily rotated by shaking during use to affect the stability of the projection.

It can be understood that the connection relationship between the second connecting rods 122 and the first connecting rod 120 and the base 14 can also be: the second connecting rod 122 is connected to the first connecting end 122a by the first connecting end 122a The middle portion of the first connecting rod 120 is movably connected, and the second connecting rod 122 is fixedly connected to the middle portion of the base 140 by its second connecting end 122b. When the pico projector 16 is used, the projection angle of the pico projector 16 is adjusted by rotating the second connecting rod 122 about the axis of the second connecting rod 122.

It can be understood that the pulley 1200 is in close contact with the slide rail 102 to increase the friction between the pulley 1200 and the slide rail 102 to prevent the first connecting rod 120 from being shaken during use. The slide rail 102 is free to slide inside to affect the stability of the projection. A concave stop groove 1022 may be disposed on the bottom surface 1020 of the slide rail 102 to position the sliding position of the first connecting rod 120 to prevent the pulley 1200 from sliding freely within the slide rail 102 to affect the projection effect.

As shown in FIG. 4, it can be understood that the rotating shaft 1420 can also be disposed on both sides 160 of the pico projector 16. The blind holes 162 may be disposed on inner side faces of the support arms 142 of the rotating portion 14 opposite to each other. The rotating shaft 1420 of the pico projector 16 is rotatably coupled within the blind hole 162 on the support arm 142 to adjust the projection angle when the pico projector 16 is used.

The portable device provided by the present invention conveniently sets a projection function on the portable device by opening a groove on the side wall to reduce the trouble of carrying and reinstalling the projector. . Secondly, the projection angle of the pico projector is conveniently adjusted during projection by placing the pico projector on a rotatable rotating portion.

It is to be understood by those skilled in the art that the above embodiments are only intended to illustrate the invention, and are not intended to limit the invention, as long as it is within the spirit of the invention Changes and modifications are intended to fall within the scope of the invention.
