## Background
BACKGROUND
1. Technical Field
The present disclosure relates to portable electronic devices and, particularly to a portable electronic device having a detachable keypad module.
2. Description of Related Art
Typically, a portable electronic device includes a first housing, a second housing, and a keypad module. The first housing securely attaches to the second housing to define an enclosing space to accommodate electronic components of the portable electronic device. The keypad module is latched inside the enclosing space. However, to replace the keypad module, the housings of the portable electronic device have to be detached/separated. Thus, it is inconvenient and time consuming.
Therefore, there is a room for improvement within the art.

DETAILED DESCRIPTION
FIG. 1 and FIG. 2 show a portable electronic device 100. The portable electronic device 100 includes a first housing 10, a second housing 20 attached to the first housing 10, a keypad module 30 detachably assembled in the first housing 10, and a resilient member 40.
The first housing 10 includes a main housing 11 and four sidewalls 12 substantially perpendicularly bent away from the main housing 11. The main housing 11 defines a window 110 and an accommodating portion 13. The window 110 is configured for displaying a liquid crystal display (LCD). The accommodating portion 13 is defined adjacent to the window 110, and configured for accommodating the keypad module 30. The sidewalls 12 include a first sidewall 121, a second sidewall 122 opposite to the first sidewall 121, and a third sidewall 123 connecting the first sidewall 121 to the second sidewall 122. The first sidewall 121 includes two protruding portions 124 positioned thereon. The second sidewall 122 includes a baffle plate 125 positioned thereon. The baffle plate 125 and the main housing 11 define a receiving slot 126 therebetween.
The keypad module 30 is rectangular. A length of the keypad module 30 is smaller than that of the accommodating portion 13. The keypad module 30 includes a first end 31, a second end 32 opposite to the first end 31, a third end 33 connecting the first end 31 to the second end 32. The first end 31 defines two sliding slots 34 corresponding to the protruding portions 124. Each of the sliding slots 34 is L-shaped, and includes a first slot 341 and a second slot 342 perpendicularly communicating with the first slot 341. The second end 32 includes a rib 35 configured for receiving the receiving slot 126. The third end 33 includes two latching posts 331 positioned thereon. Each of the latching posts 331 defines a fixing hole 332 therein.
The resilient member 40 is a spring or an elastic sheet. In an exemplary embodiment, the resilient member 40 is an elastic sheet. The resilient member 40 is arch-shaped, and includes two ends respectively secured in the fixing hole 332. The resilient member 40 is resists the third sidewall 123, and is configured for providing elastic force to the keypad module 30.
Referring to FIG. 3, in assembly, the rib 35 is received in the receiving slot 126. The keypad module 30 is pushed to the third sidewall 123 by an external force, and the resilient member 40 resists the third sidewall 123 and generates an elastic force. The first end 31 is pressed downwardly to receive the protruding portions 124 in each of the first slots 341. The second end 32 resists the baffle plate 125, thereby the keypad module 30 cannot separate from the first housing 10. The keypad module 30 is biased away from the third sidewall 123 by the elastic force of the resilient member 40. The protruding portions 124 slide into each second slot 342.
When the keypad module 30 is to be detached, the keypad module 30 is pushed to the third sidewall 123 by an external force, and the resilient member 40 is compressed. The protruding portions 124 respectively align with each first slot 341. The first end 31 is pressed by an external force and drops off from the first sidewall 121. The rib 35 slides out of each receiving slot 126. Then the keypad module 30 can be detached from the first housing 10.
Referring to FIG. 4, the length of the keypad module 30 is smaller than that of the accommodating portion 13, thereby when the keypad module 30 is assembled in the first housing 10, the keypad module 30 and the third sidewall 123 define a gap 50 therebetween. The portable electronic device 100 further includes a decorative bar 60 made of, for example, rubber. The decorative bar 60 includes two clasps 61 positioned at two opposite ends thereof. The clasps 61 latch to the first housing 10 to secure the decorative bar 60 in the gap 50.
It is to be understood, however, that even through numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
