Portable electronic device

A portable electronic device includes a main body, a casing and a supporting unit. The casing is detachably connected to the main body. The supporting unit is connected to the casing and is rotatable relative to the casing. When the supporting unit rotates to a first position, the supporting unit supports the main body. When the supporting unit rotates to a second position, the casing and the main body are separated.

BACKGROUND OF THE INVENTION

1. Field of Invention

The invention relates to an electronic device and, more particularly, to a portable electronic device.

2. Related Art

Portable electronic devices, such as a mobile phone or a personal digital assistant (PDA), become more and more necessary in life. Since the portable electronic device may not be connected to a power source at anytime conveniently, the user may need to replace the battery periodically.

FIG. 1is a schematic diagram showing a conventional mobile phone1. A back cover11of the mobile phone1is fastened to a main body12. To replace the battery, the user may use the fingertip or the nail to push a latch111to separate the back cover11from the main body12.

However, since the size of the latch111is too small to be forced to, the user may get injured or damage the back cover11due to an inappropriate force.

SUMMARY OF THE INVENTION

A portable electronic device with a casing for easy detached is disclosed. The portable electronic device includes a main body, a casing and a supporting unit. The casing is detachably connected to the main body. The supporting unit is connected to the casing and rotatable relative to the casing. When the supporting unit rotates to a first position, the supporting unit supports the main body, and when the supporting unit rotates to a second position, the casing and the main body are separated.

DETAILED DESCRIPTION OF THE INVENTION

A portable electronic device is illustrated with relating figures.

FIG. 2Ais a schematic diagram showing a portable electronic device2, andFIG. 2Bis an exploded diagram showing a casing22and a supporting unit23.

The portable electronic device2may be a mobile phone, a personal digital assistant (PDA), a video player or a play station portable (PSP). The mobile phone is taken as an example herein, which is not limited. The portable electronic device2includes a main body21, a casing22and a supporting unit23.

The main body21may include a display, an input module and a power supply (not shown). The display module or the input module can be a touch control panel for example. The power supply is disposed between the main body21and the casing22.

The casing22includes a plurality of fasteners221, and the casing22is fastened to the main body21via the fasteners221, which is not limited herein. The casing may also be locked or inserted to the main body according to different requirements.

The supporting unit23is connected to the casing22and rotatable relative to the casing22. The supporting unit23includes a supporting element231and a connecting element232. The connecting element232is pivotally connected to the casing22, the supporting element231is connected to the connecting element232, and the supporting element231and the connecting element232may be integratedly formed or independently formed, which is not limited herein. The supporting unit23may be fastened, locked, inserted or magnetically attached to the casing22.

FIG. 3is a schematic diagram showing a portable electronic device2in operation. When the user rotates the supporting unit23outwards from the casing22to a first position, the supporting unit23, as a stand, supports the main body21at a horizontal plane. The supporting unit23may be fastened to the casing22via a fixing structure such as a latch to fix the supporting unit23at the first position.

FIG. 4Ais a sectional schematic diagram showing a portable electronic device2in operation, andFIG. 4Bis a schematic diagram showing the casing22and the supporting unit23separated from the main body. If the supporting unit23is at the first position and the user continues rotating the supporting unit23away from the casing22, one end233of the supporting unit23abuts against the main body21as a supporting point, and the supporting element231would be regarded as an arm of force. Thus, if the user continues applying force on the supporting unit23, the casing22is separated from the main body21under the force on the end233of the supporting unit23, and the supporting unit23rotates to a second position (as shown inFIG. 4B).

In sum, the portable electronic device includes a supporting unit. When the supporting unit rotates to a first position, the supporting unit supports the main body. When the user continues rotating the supporting unit, since one end of the supporting unit abuts against the main body and is regarded as a supporting point, and the supporting unit is regarded as an arm of force, the user can rotate the supporting unit to a second position and separate the casing from the main body easily. Thus, the user does not need to use the fingertip or the nail to apply force, and they can detach the casing22easily without worrying about getting injured or damaging the casing22.
