1 is an exploded perspective view of a portable electronic device according to a preferred embodiment of the present invention; FIG. 2 is an exploded perspective view of the portable electronic device shown in FIG. 1; FIG. FIG. 4 is a partially exploded perspective view of a portable electronic device according to another preferred embodiment of the present invention. FIG.

The portable electronic device of the present invention can be a mobile phone, a personal digital assistant (PDA), etc. In this embodiment, a mobile phone is taken as an example for illustration.

Referring to FIG. 1 and FIG. 2, the mobile phone 100 includes a first housing 10 and a first The second housing 20, a button module 30 and an elastic member 40. The first housing 10 is coupled to the second housing 20 to receive internal components (not shown) of the mobile phone 100. The button module 30 is disposed on the first housing 10 to implement information input to the mobile phone 100.

The first housing 10 is substantially a square frame, and includes a bottom wall 11 and four side walls 12 bent from the edge of the bottom wall 11. The bottom wall 11 is provided with a display device 110 adjacent to one end thereof, and an opening 13 corresponding to the button module 30 is disposed adjacent to the other end thereof. The display device 110 is configured to display internal information of the mobile phone 100, which may be a liquid crystal display. The opening 13 is configured to receive the button module 30. The sidewall 12 includes a first sidewall 121 , a second sidewall 122 opposite to the first sidewall 121 , and a third sidewall 123 adjacent to the first sidewall 121 and the second sidewall 122 . Two protrusions 124 are protruded from the first sidewall 121. The second sidewall 122 extends a baffle 125 toward the first sidewall 121. A receiving groove 126 is defined in the second sidewall 122 between the baffle 125 and the bottom wall 11.

The button module 30 is substantially a square plate-like body having a length smaller than the length of the opening 13. The button module 30 includes a first end portion 31 , a second end portion 32 opposite to the first end portion 31 , and a third end adjacent to the first end portion 31 and the second end portion 32 . Part 33. Two sliding slots 34 are defined in the first end portion 31. Each of the sliding slots 34 includes a connecting port 341 and a slot 342. The connecting port 341 and the slot 342 communicate with each other and are connected in an inverted "L" shape. The two protrusions 124 can be respectively held in the sliding slot 34. The second end portion 32 extends away from the first end portion 31 by a rib 35 that can be received in the receiving groove 126. The second end portion 33 has two latching holes 331. The two latching holes 331 respectively define a fixing hole 332.

The elastic member 40 is an arched elastic piece, and the two ends of the elastic member 40 are respectively received in the fixing hole 332 for being fixed on the button module 30. The elastic member 40 can resist the third side wall 123 to provide elastic force to the button module 30.

Referring to FIG. 3 , when the button module 30 is assembled, the rib 35 of the second end portion 32 of the button module 30 is first received in the receiving groove 126 of the second sidewall 122 . Then, the button module 30 is pushed to slide in the direction of the third side wall 123, so that the elastic member 40 is abutted on the third side wall 123. The button module 30 is continued to be pushed toward the third side wall 123 to deform the elastic member 40 to generate elastic potential energy. The first end portion 31 is pressed to receive the two protrusions 124 of the first side wall 121 respectively in the connection port 341 on the first end portion 31. At this time, the button module 30 is abutted against the baffle 125 adjacent to the second end portion 32, so that the button module 30 does not fall off the first housing 10. Finally, the button module 30 is released, and the button module 30 slides away from the third side wall 123 by the elastic potential energy of the elastic member 40, so that the protrusions 124 are respectively slid into the card slot 342.

When the button module 30 is removed, an external force is applied to the button module 30 in the direction of the third side wall 123, thereby compressing the elastic member 40, so that the two protrusions 124 slide in the card slot 342 until the button block 342 is pressed. The two bumps 124 are aligned with the connection port 341. At the same time, an external force is applied to the first end portion 31 to disengage the first end portion 31 of the button module 30 from the first side wall 121. The rib 35 is further detached from the accommodating groove 126 to remove the button module 30.

It can be understood that the button module 30 can be assembled in the first housing 10 by the rib 35 and the receiving groove 126 and the sliding groove 34 and the protrusion 124, so the baffle 125 can be omitted.

It can be understood that the elastic member 40 is not limited to the arched elastic piece, and may be a compression spring or the like.

It can be understood that, as shown in FIG. 4 , since the length of the opening 13 is greater than the length of the button module 30 , the elastic component 40 forms a gap between the button module 30 and the third sidewall 123 when the button module 30 is mounted. 50. The gap 50 affects the aesthetics of the mobile phone 100, so a decorative sheet 60 can be disposed at the notch 50. The decorative sheet 60 is made of a soft material, which is substantially the same size as the notch 50, and a hook 61 is respectively disposed at each end of the decorative sheet 60. The hooks 61 can be respectively clamped on the first casing 10 on both sides of the notch 50 to cover the notch 50, so as to beautify the appearance of the mobile phone 100.

It can be understood that the elastic member 40 and the two latches 331 of the fixed elastic member 40 can be omitted. The elastic force provided by the elastic member 40 for the button module 30 can be replaced by an external force provided by the user to the button module 30, that is, the external force will be The button module 30 slides away from the third side wall 123, so that the protrusions 124 are respectively slid into the card slot 342. The indentation 50 is formed between the button module 30 and the third side wall 123. The decorative sheet 60 is mounted in the notch 50 and resists the button module 30 to prevent the button module 30 from being oriented. The three side walls 123 slide in the direction.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in accordance with the spirit of the present invention are It should be covered by the following patent application.
