## Background
BACKGROUND
1. Technical Field
The present disclosure relates to notebook computers and, particularly, to angular adjustments of the screen of a notebook computer.
2. Description of Related Art
When using a notebook computer in front of an audience, it is not uncommon for the presenter to show the screen while operating the keyboard simultaneously. Therefore, the presenter needs to repeatedly turn the notebook computer 180 degrees back and forth. This is an inconvenience.
What is needed, therefore, is a notebook computer, which can overcome the above-described problem.

DETAILED DESCRIPTION
Embodiments of a notebook computer will now be described in detail with reference to the drawings.
Referring to FIGS. 1-3, a notebook computer 100, according to an exemplary embodiment, includes a main body 10, two connecting assemblies 20, and a display 30.
The main body 10 is cuboid in shape and includes a rectangular upper surface 11 and two first joint members 12. The two first joint members 12 are shafts correspondingly extending upwards from two corners of the rectangular upper surface 11. Each of the first joint members 12 defines a first shaft hole 121. The two first shaft holes 121 are aligned with each other.
Referring to FIGS. 3-4, each of the connecting assemblies 20 includes an arm 21, a connecting shaft 22, a stop sleeve 23, a stop cover 24, a first shaft 25, and a second shaft 26.
The arm 21 is a hollow rectangular rod in shape and includes a pair of first side surfaces 211 and a pair of second side surfaces 212. The arm 21 defines a second shaft hole 213a through one distal end 213. In particular, the second shaft hole 213a extends through the second side surfaces 212. In addition, the arm 21 defines a receiving slot 215 in the other distal end 214, forming two holding plates 216. Each of the holding plates 216 defines a first sleeve hole 216a. The two first sleeve holes 216a are aligned with each other and extend through the first side surfaces 211.
The connecting shaft 22 is a hollow cylindrical rod. The connecting shaft 22 is made of an anti-abrasive material.
The stop sleeve 23 is shaped and sized corresponding to the arm 21. In particular, the stop sleeve 23 is rectangular in shape and has an inner cross section slightly greater than the cross section of the arm 21.
The stop cover 24 includes a base 241, a spacing plate 242, and two side plates 243. The base 241 is a rectangular plate. The spacing plate 242 extends uprightly from one edge of the base 241. The two side plates 243 extend uprightly from opposite edges of the base 241 correspondingly and both connect to the spacing plate 242. The spacing plate 242 is disposed between the side plates 243. Each of the side plates 243 defines a second sleeve hole 243a in one end away from the spacing plate 242. The two second sleeve holes 243a are aligned with each other.
In assembly of the connecting assemblies 20, the connecting shaft 22 is perpendicularly connected to one of the first side surfaces 211 adjacent to the distal end 213. The stop sleeve 23 moveably sleeves onto the distal end 214 of the arm 21. The second shaft 26 inserts through the second sleeve hole 243a and the second shaft hole 213a. Therefore, the stop cover 24 is rotatably fixed at the distal end 213.
The display 30 such as a liquid crystal display (LCD) is shaped corresponding to the main body 10, and includes a screen 31, a frame 32, and a position sensor 33. The frame 32 surrounds the screen 31. The frame 32 includes a pair of first sidewalls 321 and a pair of second sidewalls 322. The frame 32 defines a pair of axle holes 321a in the first sidewalls 321 correspondingly. The position sensor 33 is mounted at one of second sidewalls 322. The position sensor 33 is configured to detect an orientation of the display 30.
In assembly, each of the first shafts 25 inserts through a corresponding first sleeve hole 216a and a corresponding first shaft hole 121. Thereby, the pair of arms 21 is rotatably connected to the main body 10. The connecting shafts 22 are inserted into the axle holes 321a correspondingly. Thereby, the display 30 is rotatably connected to the arms 21. It should be mentioned that a friction force between the connecting shaft 22 and the axle hole 321a is strong enough to hold the display 30 in any desired angles.
In addition, the main body 10 and the display 30 are connected via two cables (not shown). The cables thread through the arm 21 and the connecting shaft 22.
Referring back to the FIG.1, when not used, the display 30 is folded. Referring back to FIG. 2, in normal use, the display 30 can be about 90 degrees unfolded corresponding to the main body 10. After the display 30 is unfolded to a desired position, the stop sleeves 23 can be pushed to sleeve both the first joint members 12 and the arms 21, thereby fixing the display 30 at the position. In any condition, the stop cover 24 holds the display 30, therefore the display 30 will not swing freely.
Further referring to the FIG. 5, when a presenter wishes to show the screen 31 to an audience or adjust a perspective, the stop cover 24 is separated from the display 30 and the presenter rotates the stop cover 24 around the second shaft 25. Then the presenter can adjust the screen 31 to a desired angle. The position sensor 33 detects the orientation of the display 30. If the display 30 is turned over, the position sensor 33 generates a control signal. The notebook computer 100 orients the image according to the control signal.
It will be understood that the above particular embodiments and methods are shown and described by way of illustration only. The principles and the features of the present invention may be employed in various and numerous embodiment thereof without departing from the scope of the invention as claimed. The above-described embodiments illustrate the scope of the invention but do not restrict the scope of the invention.
