Please refer to Figures 1 and 2 for the mobile power supply of the present invention. The mobile power supply 100 of the present invention mainly comprises a body 10, a lifting unit 20 and a micro-projection unit 30, the configurations of which are respectively described below.

In this embodiment, the body 10 has a substantially rectangular parallelepiped shape and has an upper surface 14 , two side surfaces 16 , a front end surface 18 , and a rear end surface 17 . A receiving portion 12 is formed on the body 10 , and the receiving portion 12 is recessed. On the opposite sides of the receiving portion 12, there are two side walls 122 and 124. The bottom portion is formed by a bottom wall 126, and the opposite sides are formed with edges 128 of a height equal to the bottom wall 126. The bottom wall 126 is connected to the side walls 122 and 124 and the body, respectively. The two sides 16 of the 10 are located at the junction of the bottom wall 126 and the side surface 16, and the side walls 122 and 124 are slightly inclined, and a slit 127 is formed in the vicinity of the two edges 128, respectively.

The lifting unit 20 includes two rocker arms 22 and two damping rotating shafts (not shown). The damping rotating shaft is disposed in the body 10, and the rocking arm 22 is rotatably coupled to the damping rotating shaft and swings with the damping rotating shaft as a center of rotation, thereby the rocker arm One end of 22 can be raised upward through the slit 127.

Referring to FIGS. 2 and 3 , the micro-projection unit 30 is substantially rectangular parallelepiped and has a front end surface 32 , a rear end surface 34 , two side surfaces 36 , a top surface 38 , and a bottom surface 37 . The projection lens 31 is disposed on the front end surface 32 . The video input port 33 is disposed on the rear end surface 34, a focus button 35 is disposed on one of the side faces 36, a heat dissipating fan 39 is disposed on the bottom surface 37, and the micro-projection unit 30 is rotatably coupled to one end of the rocker arm 22, and is shaken The swing of the arm 22 is movable between a first position (as shown in Figure 1) and a second position (as shown in Figure 2).

When the micro-projection unit 30 is in the first position, the micro-projection unit 30 is received in the accommodating portion 12 of the body 10, and the front end surface 32 and the rear end surface 34 are respectively adhered to the two side walls 122 and 124 of the accommodating portion 12 for projection. The lens 31 and the video input port 33 are hidden and shielded in the accommodating portion 12, and the top surface 38 is flush with the upper surface 14 of the body 10. The two side surfaces 36 are flush with the two side surfaces 16 of the body 10, so that the projection lens 31 is prevented from being exposed. When it is carried outside, it is scratched by fingerprints or dust, and the audio-visual input port 33 can also prevent foreign matter from entering. After storage, the mobile power supply 100 of the present invention has an outer size similar to that of a general mobile power supply. When the user presses a projection start key 9 disposed on the front end surface 18 of the main body, the micro-projection unit 30 is slowly raised to the second position by the damper of the damper shaft and the rocker arm 22, and the micro-projection unit 30 is detached from the accommodating. The portion 12 exposes the projection lens 31 and the video input port 33 while starting the power of the micro-projection unit 30, and the light can be projected to the outside via the projection lens 31. Since the micro-projection unit 30 is rotatably coupled to one end of the rocker arm 22, The projection angle of the micro-projection unit 30 can be adjusted by this, and since the micro-projection unit 30 located at the second position has a certain distance from the bottom wall 126 of the accommodating portion 12, a heat dissipation space is formed to facilitate the cooling fan 39 to take hot air. The discharge, focus button 35 is used to adjust the focal length of the projection lens 31 to facilitate the clear projection of the image onto the screen.

In this embodiment, the projection start key 9 is disposed on the body 10, but It is understood that the projection start key 9 can also be modified to be disposed on the micro-projection unit 30, which is also within the scope of the present invention.

In this embodiment, the video input port 33 of the micro-projection unit 30 includes a miniUSB image input port or a miniHDMI image input port.

In the present embodiment, the video input port 33 is disposed on the micro-projection unit 30. However, it can be understood that the video input port 33 can also be modified on the body 10, which is also within the scope of the present invention.

In the present embodiment, a battery charging jack 5, a miniUSB power input port 6, and a USB power source output port 7 are formed at the rear end surface 17 of the body 10.

After the micro-projection unit 30 of the present invention is stored, the projection lens 31 and the video input port 33 on the other side are hidden inside the body, which can prevent the projection lens 31 from being scratched and contaminated by fingerprints or dust when being carried outside, and the audio-visual input. The 埠33 can also avoid foreign matter intrusion. After storage, the mobile power supply 100 of the present invention has an outer size similar to that of a general mobile power supply.
