This application claims priority to Taiwan Application Serial Number 95137226, filed Oct. 5, 2006, which is herein incorporated by reference.
The invention relates to a mobile phone and, more particularly, to an assembling structure of covers for a mobile phone.
Conventionally, the back of a mobile phone (the face without a screen) usually has covers for a user to disassemble to replace a battery or covers with different colors. Most of the conventional back covers include antenna covers and battery covers.
A disassembling method of a battery cover should be convenient to a user, while an antenna cover is usually fixed to the main body of a mobile phone since it does not designed to be directly disassembled by the user. However, the fixed antenna cover also makes inconvenience for a serviceman, so that it is inconvenient for the service. Especially, when an serviceman disassembles the antenna cover to test the mobile phone, he may damage the antenna cover thus to affect the appearance or cause a requirement of changing back covers.
Therefore, an objective of the invention is to provide an assembling structure of back covers for a mobile phone which is convenient to be assembled and disassembled.
According to the above objective, a mobile phone is provided. The mobile phone at least includes a first back cover, a second back cover and a main body. The first back cover has a first fastening part on its inner wall, and the second back cover has a first interfering part on its inner wall. The first back cover and the second back cover are assembled with the main body. The main body has a resilient hook including a resilient arm, a second fastening part and a second interfering part. One end of the resilient arm is fixed to the main body, and the second fastening part is provided at the other end of the resilient arm. The second interfering part is provided at the resilient arm. When the first back cover and the second back cover are assembled with the main body, the first fastening part is fastened with the second fastening part to fix the first back cover. When the second back cover is separated from the main body, the first interfering part pushes against the second interfering part to drive the second fastening part to separate from the first fastening part by the resilient arm, so that the first back cover can separate from the main body.
In an embodiment of the invention, the first fastening part may be a recess, and the second fastening part may be a hook part.
In an embodiment of the invention, the first interfering part and the second interfering part may be circular arc protrusions.
FIG. 1 is a structural diagram showing a main body of a mobile phone according to an embodiment of the invention.
FIG. 2 is a structural diagram showing an antenna cover of a mobile phone according to an embodiment of the invention.
FIG. 3 is a structural diagram showing a battery cover of a mobile phone according to an embodiment of the invention.
FIG. 4 is a section diagram showing a mobile phone after being assembled with an antenna cover and a battery cover according to an embodiment of the invention.
FIG. 5 is a section diagram showing a method for disassembling the antenna cover and the battery cover in FIG. 4.
As described above, the invention provides an assembling structure of covers for a mobile phone, which is suitable for a mobile phone with two covers. The following embodiments provide details of the invention.
FIG. 1 is a structural diagram showing a main body of a mobile phone according to an embodiment of the invention. FIG. 1 shows the main body 100 without being assembled with back covers and an enlarged view of an assembling structure. The assembling structure includes a resilient hook and assembling hooks 110, 112 and 114. The resilient hook includes a resilient arm 102, wherein one end of the resilient arm 102 is fixed to the main body 100 to support the other end (a free end 106). The free end 106 includes an inclined surface 106 a and a fastening part (such as a hook part 106 b), and the inclined surface 106 a is connected with the hook part 106 b. Further, an interfering part (such as a circular arc protrusion 104) is provided on the resilient arm 102. This figure shows only one of a pair of resilient hooks.
FIG. 2 is a structural diagram showing an antenna cover of a mobile phone according to an embodiment of the invention. FIG. 2 shows the inner wall (the upper right diagram) and the outer wall (the lower left diagram) of the antenna cover 120. A fastening part (such as a recess 122) on the inner wall of the antenna cover 120 corresponds to the fastening part (such as the hook part 106 b) of the resilient hook in FIG. 1 when it is assembled. Further, the antenna cover 120 further includes a plurality of assembling hooks 124 and 126 for fastening with a plurality of recesses (such as a recess 108, and the other recesses are not shown in the figures) of the main body 100.
FIG. 3 is a structural diagram showing a of a battery cover of a mobile phone according to an embodiment of the invention. FIG. 3 shows the inner wall (the upper left diagram) and the outer wall (the lower right diagram) of the battery cover 130. An interfering part (such as a circular arc protrusion 132) on the inner wall of the battery cover 130 corresponds to the interfering part (such as the circular arc protrusion 104) of the resilient hook in FIG. 1 when it is assembled. Furthermore, the battery cover 130 further includes a plurality of assembling hooks 134, 136 and 138 for fastening with the plurality of assembling hooks 110, 112 and 114 of the main body 100. For example, the assembling hook 134 is fastened with the assembling hook 110; the assembling hook 136 is fastened with the assembling hook 112; the assembling hook 138 is fastened with the assembling hook 114.
FIG. 4 is a section diagram showing a mobile phone after being assembled with an antenna cover and a battery cover according to an embodiment of the invention. Most parts of the antenna cover 120 and the battery cover 130 in FIG. 4 are removed in the section diagram, and only the parts assembled with the main body remain. When the antenna cover 120 and the battery cover 130 are assembled with the main body 100, elastic force of the resilient arm 102 makes the hook part 106 b be fastened at the recess 122 to fix the antenna cover 120 and makes the circular arc protrusion 104 restrict the circular arc protrusion 132 to fix the battery cover 130, and the assembling end 128 of the antenna cover 120 is between the resilient arm 102 and the battery cover 130. The inclined surface 106 a makes the hook part 106 b easily slide into the recess 122. The assembling end 128 also has an inclined surface 128 a for making the battery cover 130 easily slide to a predetermined position.
FIG. 5 is a section diagram showing a method for disassembling the antenna cover and the battery cover in FIG. 4. When the antenna cover 120 and the battery cover 130 are to be assembled, the battery cover 130 is withdrawn along the direction 140 first. The circular arc protrusion 132 of the battery cover 130 pushes against the circular arc protrusion 104 to deform the resilient arm 102. When the top of the circular arc protrusion 132 contacts the top of the circular arc protrusion 104, the resilient arm 102 is deformed to the greatest degree and the hook part 106 b is separated from the recess 122; thus the antenna cover 120 can be withdrawn only along a direction 150 at that moment.
From the above, the battery cover 130 can be easily disassembled to replace batteries by a user, while a skill is needed to disassemble the antenna cover 120. The objective of above design is not to enable the user to disassemble the antenna cover 120. However, for a serviceman, he can disassemble the antenna cover 120 only if he knows the skill.
Although the above embodiments takes the antenna cover 120 and the battery cover 130 for example, this assembling structure of covers also applies to other back covers for a mobile phone.
According to the above, the assembling structure of covers according to the invention can enable the antenna cover and the battery cover be disassembled easily only by a single resilient hook cooperating with other assembling hooks. Furthermore, the user only can easily disassemble the battery cover, while the serviceman knowing the disassembly skill can easily disassemble the antenna cover.
