## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is related to two co-pending U.S. patent application Ser. Nos. 12/953,772, and 12/947,999, entitled “METAL HOUSING AND ELECTRONIC DEVICE USING THE SAME” and “METAL HOUSING AND FABRICATION METHOD THEREOF”, respectfully, by Zi-Ming Tang et al. The above-identified applications have the same assignee as the instant application and are concurrently filed herewith.

BACKGROUND
1. Technical Field
The present disclosure relates to device housings and particularly, to a housing of an electronic device.
2. Description of the Related Art
An electronic device often includes a bottom shell, a support frame, and a display. The support frame is fixed on the bottom shell. The screen is fixed on the support frame. However, upon impact, the display screen and the bottom shell are easily damaged due to having insufficient structural strength at the corners of the display screen and the bottom shell.
Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION
FIGS. 1 and 2 show one embodiment of a housing 50 for an electronic device 100 that includes a display screen 40 and other various functional modules (not shown). The other various functional modules are used to implement a variety of appropriate functions such as telephony, playing audio or other functions. The electronic device 100 can be a touch panel, a cell phone, a MP3 (Moving Picture Experts Group Audio Layer III) player, a PDA (Personal Digital Assistant), a digital photo frame or a liquid crystal display. In the illustrated embodiment, the electronic device 100 is a touch panel device. The metal housing 50 includes a bottom shell 10, a support frame 20, and four protection blocks 30. The support frame 20 is fixed in the bottom shell 10 with the protection blocks 30. The display screen 40 is fixed on the support frame 20.
The bottom shell 10 is substantially rectangular, and includes a bottom plate 11 and four side plates 12. The bottom plate 11 is substantially rectangular. The four side plates 12 extend from a periphery of the bottom plate 11. Each side plate 12 is substantially curved. A connecting portion of two adjoining side plates 12 is also substantially curved.
Referring to FIGS. 3 and 4, the support frame 20 is substantially rectangular, and includes four reinforcement side walls 21 connecting in order. The support frame 20 includes four receiving portions 22 and four elongated grooves 23. The four receiving portions 22 are defined in four corners of the support frame 20 to receive the four protection blocks 30. The elongated grooves 23 are substantially rectangular strip-shaped, and defined in the top surfaces of the four reinforcement side walls 21, respectively. Glue (not shown) is received in the elongated grooves 23, such that the support frame 20 is fixed in the bottom shell 10.
Referring to FIG. 5, each protection block 30 is substantially pyramidal, and includes a curved surface 31 and two adhesive grooves 32. The curved surface 31 is defined in a side surface of the each protection block 30. The two adhesive grooves 32 are defined at two adjoining edges of the curved surface 31 to receive glue (not shown). Each protection block 30 is made of an alloy of hardness exceeding 50 HR, such as stainless steel or tungsten steel.
When the electronic device 100 is subjected to an external force, for example, a drop, the protection blocks 30 absorb the external force, such that the housing 50 and the display screen 40 are protected from damage by the protection blocks 30. Furthermore, the protection blocks 30 are fixed between the support frame 20 and the bottom shell 10 to save the occupied volume of the electronic device 100, such that the electronic device 100 can be more and more thinner.
It is to be understood that the side plates 12 can also extend perpendicular to the bottom plate 11. The elongated grooves 23 can also be omitted, wherein the support frame 20 is fixed to the bottom shell 10 by welding or hook structures. The adhesive grooves 32 of the protection blocks 30 can also be omitted, wherein the protection blocks 30 are fixed in the bottom shell 10 by welding.
Finally, while the present disclosure has been described with reference to particular embodiments, the description is illustrative of the disclosure and is not to be construed as limiting the disclosure. Therefore, various modifications can be made to the embodiments by those of ordinary skill in the art without departing from the true spirit and scope of the disclosure as defined by the appended claims.
