1. Field of the Invention
The disclosure relates to battery cover mechanisms, particularly to a battery cover mechanism used in portable electronic devices.
2. Description of Related Art
Portable electronic devices such as mobile phones and personal digital assistants (PDAs) are widely used. When a battery is installed in the portable electronic device, the battery is generally shielded and fixed in place by a battery cover mechanism.
A commonly used battery cover mechanism includes a cover and a housing. The cover includes a pin at on one end and a protrusion at an opposite end. The housing defines a receiving hole and a holding aperture. The protrusion can be received in the holding aperture, and the cover impelled towards the housing until the pin is received into the receiving hole. As such, the cover securely engages the housing by protrusion seated in the holding aperture. However, the cover usually needs to be separated from the housing for removing a battery from the housing. Therefore, the cover may be easily lost.
Therefore, there is room for improvement within the art.
Many aspects of the present battery cover mechanism can be better understood with reference to the following drawings. The components in the various drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present battery cover mechanism. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the diagrams.

The housing 10 includes a bottom wall 12 and a peripheral wall 14 perpendicularly extending from the periphery of the bottom 12. The bottom wall 12 forms a holding frame unit 122. The holding frame unit 122 includes spaced-apart, oppositely shaped, parallel holding blocks 124. Each of the two holding blocks 124 is generally L-shaped and includes a top wall 1242 parallel with the bottom wall 12, a sidewall 1244 and an end wall 1246. The sidewall 1244 and the end wall 1246 connect with each other perpendicularly, and perpendicularly connect to the top wall 1242 and the bottom wall 12. The spaced-apart holding blocks 124 and the bottom wall 12 cooperatively enclose a receiving space 1248 defining a first opening 1247 and a second opening 1249. The receiving space 1248 is used to receive the battery 200. The first opening 1247 is defined by the two end walls 1246 and facilitates passing of the second elastic member 60 through for abutting the battery 200. The second opening 1249 is aligned opposite to the first opening 1247 and facilitates inserting of the battery 200 into the receiving space 1248.
The peripheral wall 14 defines a cutout 142. The cutout 142 is aligned with the second opening 1249 and facilitates passing the battery 200 through the cutout 142 and the second opening 1249 into the receiving space 1248. The peripheral wall 14 has a latching portion 144 formed thereon, the latching portion 144 faces the cutout 142, abuts the bottom wall 12, and is used to engage the second elastic member 60. The latching portion 144 includes two L-shaped latching boards 1442, which are symmetrically positioned on the peripheral wall 14 to enclose a gap 1444.

The door 20 includes a main board 22 and a rib 24 at each side of the main board 22. The main board 22 has a front surface 222 and a back surface (not labeled). The front surface 222 forms a plurality of strips 224 for providing friction when sliding the door 20. The two ribs 24 extend laterally from their respective sides of the back surface. The ribs 24 are used to slidably engage into the guiding slots 1267.
The first elastic member 30 is a coil spring and can be received in the chamber section 1268 of the latching seat 126.
The holding unit 40 is a bar defining two second connecting holes 42 corresponding to the two first connecting holes 1269.
The fixing member 50 can be a screw passed through the second connecting hole 42 and screwed into the first connecting holes 1269 to fix the holding unit 40 to the housing 10. The holding unit 40 encloses the chamber section 1268 so that the first elastic member 30 is resisted by the holding unit 40 to be accommodated in the chamber section 1268.
The second elastic member 60 is a coil spring including a positioning end 62 and a resisting end 64. The positioning end 62 can be secured into the latching portion 144 of the peripheral wall 14 and the resisting end 64 extends through the gap 1444 to resist the battery 200.
To assemble the battery cover mechanism 100, the door 20 is mounted to the housing 10. The two ribs 24 of the door 20 are received in their respective guiding slots 1267 of the two latching seats 126 and positioned into their respective chamber sections 1268. The door 20 closes off the cutout 142 of the housing 10 until the ribs 24 reach to the bottom wall 12. Then, the first elastic members 30 are placed into their respective chamber sections 1268 and the ends of the first elastic members 30 resist their respective ribs 24. The other opposite ends of the first elastic member 30 expose out of the chamber sections 1268. After that, the holding unit 40 is assembled in the housing 10, the two second connecting holes 42 of the holding unit 40 is aligned above the first connecting holes 1269 of the latching seat 126, the two fixing members 50 passed through the second connecting holes 42 and screw into their respective first connecting holes 1269, thereby, fixing the holding unit 40 with the housing 10. The first elastic members 30 are compressed by the pressing of the holding unit 40. The ribs 24 are resisted by the first elastic members 30. Then, the second elastic member 60 is assembled in the housing 10. In this case, the positioning end 62 is secured into the latching portion 144 of the peripheral wall 14, the resisting end 64 out of the gap 1444 passes through the first opening 1247 and enters into the receiving space 1248.
