## Background
BACKGROUND
1. Technical Field
The disclosure relates to portable electronic devices, especially to a portable electronic device with an adjustable cover.
2. Description of Related Art
Portable electronic devices, such as mobile phones, notebooks, and others, often have a base and a cover with a display. The cover is fixed to the base such that the display can only be adjusted on one axis, causing inconvenience of use.
Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
FIG. 1 shows an exemplary embodiment of a portable electronic device 100. The portable electronic device 100 includes a base 11, a cover 30, and a connecting module 50. The cover 30 is rotatably and pivotally attached to the base 10 by the connecting module 50.
Referring to FIG. 2, the base 10 includes an upper surface 11, a lower surface 13 opposite to the upper surface 11, a first sidewall 17 and a second sidewall 19 opposite to the first sidewall 17. Two ridges 15 are formed on the upper surface 11, each approximately parallel to the sidewalls 17, 19. The upper surface 11 can further include a keypad (not shown) enabling input to the portable electronic device 100. Each ridge 15 defines at least one notch 151, therein. The exposed surfaces of the ridges 15 are curved. The base 10 defines a receiving cavity 131, a connecting hole 171 in the first sidewall 17 communicating with the receiving cavity 131, and a receiving hole 191 in the second sidewall 19. In this exemplary embodiment, the connecting hole 171 and the receiving hole 191 are coaxial.
The cover 30 includes a first surface 31, a second surface 33 opposite to the first surface 31, a first end wall 35, and a second end wall 37 opposite to the first end wall 35. The first surface 31 may have a display 311 for displaying information. In this exemplary embodiment, the display 311 is a touch-screen, additionally providing input to the portable electronic device 100 thereby. The cover 30 defines a connecting hole 351 at an approximate center of the first end wall 35, a receiving cavity 331 communicating with the connecting hole 351, and a receiving hole 371 at the approximately center of the second end wall 37.
The connecting module 50 includes two connecting plates 51, two hinges 53 respectively received in the receiving cavities 131, 331, and two pins 55 respectively received in the receiving holes 191, 371. Each connecting plate 51 defines a receiving cutout 511 at each end. Each hinge 53 includes a housing 531 and a shaft 533 rotatably attached to the housing 531. The shaft 533 rotates to an included angle of 180° or less relative to the housing 531. In the exemplary embodiment, the included angle is 30° to 120°, and preferably the included angle is about 60°.
During assembly of the portable electronic device 100, the housings 531 of the hinges 53 are respectively received in the receiving cavities 131, 331, and the shafts 533 pass through and extend out of the connecting holes 171, 351. One of the connecting plates 51 is rotatably attached to the two hinges 53 by the shafts 533, each shaft 533 received in a corresponding cutout 511. The two pins 55 respectively pass through the cutouts 511 of the other connecting plate 51 and are rotatably received in the receiving holes 191, 371. Thus, the portable electronic device 100 is assembled, as shown in FIG. 3. When closed, the cover 30 covers the upper surface 11 of the base 10 to protect the keypad.
To adjust the display 311 relative to the base 10 or expose the upper surface 11, the user pushes cover 30 towards the receiving cavity 131 and the cover 30 then slides along the ridges 15 of the base 10. The edge of the cover 30 adjacent to the receiving cavity 131 rotates upwards from the upper surface 11 due to the restriction of the connecting plates 51 and the other edge of the cover 30 ride the ridges 15 until received in the notches 151, whereby the cover 30 stays at a fixed angular position relative to the upper surface 11. The cover 30 can be further pushed until the shafts 533 of the hinges 53 rotate to a maximum angle relative to the housings 531, and the cover 30 slides and rotates relative to the base 10 such that the display 311 can be adjusted to a preferred maximum angle.
It is notable that one of the hinges can be replaced by a pin, and the pins can be replaced by hinges. The notches 151 of the ridges may be omitted. Further, at least part of the base 10 and cover 30 can include magnetic materials with different polarities or soft magnetic material such that the base 10 attracts the cover 30 by magnetic force when the portable electronic device 100 is closed.
The cover 30 provides translational and rotational movement relative to the base 10 and can accordingly be adjusted to a preferred position along multiple axes. Further, one edge of the cover 30 rides the ridges 15 so the movement is smooth and stable.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the disclosure.
