The battery cover forms two hooks. The latching member is slidably attached to the base body. The latching member defines two hook holes. The elastic rod is attached to the base body and provides an elastic force to the latching member.

## Background
BACKGROUND
1. Technical Field
The present disclosure generally relates to battery cover assemblies and, particularly, to a battery cover assembly for use in a portable electronic device.
2. Description of Related Art
Batteries are widely used in portable electronic devices, such as personal digital assistants (PDAs), and mobile phones. Conventional batteries are removably installed in the electronic device, and battery covers are designed to connect to housings of the electronic devices to cover and protect the batteries. Batteries are replaced by opening the battery covers when, for example, the batteries are damaged and/or dead.
Although battery cover assemblies may be simple, engagement between the battery cover and the housing of the mobile phone can be too firm to be easily undone.
Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION
FIG. 1 shows a portable electronic device 100, such as a mobile phone, having a battery cover assembly. The mobile phone 100 is an exemplary embodiment of a battery cover assembly. The battery cover assembly includes a base body 10, a battery cover 30, an elastic rod 51, and a latching member 53. The elastic rod 51 and the latching member 53 releasably latch the battery cover 30 to the base body 10.
The battery cover 30 has a shape corresponding to the base body 10 and is configured to be attached to the base body 10. Two hooks 3111 extend from one end of the battery cover 30, and two catches 3131 extend from another end of the battery cover 30.
Referring to FIG. 2, the base body 10 includes a first surface 11 and an opposite second surface 12. The first surface 11 defines a cavity 111 for receiving a battery (not shown). The base body 10 includes a first end portion 13 and an opposite second end portion 14. The second end portion 14 defines two catch holes 141 for receiving the catches 3131.
Referring to FIGS. 3 and 4, the first end portion 13 includes a pressed portion 131 and a receiving portion 133. The pressed portion 131 is substantially an elastic wave plate, and is formed adjacent to the cavity 111. A slit 1311 is defined in each of two sides of the pressed portion 131 to allow the pressed portion 131 to move downward when pressed. Two blocks 1313 are formed on the pressed portion 131 facing the second surface 12. A latching groove 137 is defined at each end of the pressed portion 131. The receiving portion 133 defines a through hole 132 and a receiving groove 134. The through hole 132 communicates with the first surface 11 and the second surface 12. The receiving groove 134 is defined in the second surface 12. A frame 1321 mounts at two sides of the through hole 132. Two positioning blocks 135 are formed at the sides of the through hole 132. Each positioning block 135 defines a slot 1351.
The elastic rod 51 passes through the latching member 53, and the ends of the elastic rod 51 are latched in the slots 1351 of the positioning blocks 135.
Referring to FIGS. 5 and 6, the latching member 53 is for unlocking or locking the battery cover 30 to the base body 10. The latching member 53 includes a base plate 533 and a resisting plate 534 integrally formed together. A button 5311 is formed at one side of the base plate 533. The base plate 533 defines two spaced hook holes 5333 adjacent to the button 5311 for latching with the hooks 3111. A support stage 5335 is formed between the hook holes 5333 one the other side of the base plate 533. An L-shape protrusion 5337 extends from the support stage 5335. A space 5336 is defined between the protrusion 5337 and the support stage 5335. The elastic rod 51 may be received in the space 5336. A stopper block 5331 is formed on the base plate 533 spaced away from the L-shape protrusion 5337. The resisting plate 534 extends from one side of the base plate 533. Two projections 5341 extend from the resisting plate 534 at the side of the button 5311.
During assembly of the battery cover assembly, first, the base plate 533 is received in the receiving groove 134, and the button 5311 is exposed from the through hole 132. The resisting plate 534 abuts the pressed portion 131. Referring to FIG. 7, the frame 1321 prevents the base plate 533 from separating from the base body 10. Referring to FIG. 8, the elastic rod 51 is received in the space 5336, and two ends of the elastic rod 51 are latched in the slots 1351. The latching member 53 is moved toward the first end portion 13 to allow the projections 5341 to be received in the latching grooves 137. To the movement of the latching member 53 deforms the elastic rod 51, thereby providing an elastic force to the latching member 53. Thus, the latching member 53 is attached to the receiving portion 133. Then, the catches 3131 at one end of the battery cover 30 are inserted into the catch holes 141, and the other end of the battery cover 30 is pressed downward with external force until the other end of the battery cover 30 firstly contacts one side of the pressed portion 131, thereby the pressed portion 131 is forced to bend toward the second surface 12. Accordingly, the blocks 1313 at the other side of the pressed portion 131 push the latching member 53 to allow the projections 5341 to separate from the latching grooves 137. The latching member 53 is unlocked, and is moved under the force of the elastic rod 51 to allow the hooks 3111 to be latched in the hook holes 5333. Thus, the battery cover 30 is assembly in the base body 10.
When the latching member 53 is attached to the receiving portion 133, the position of the hook hole 5333 is spaced from the hooks 3111 of the battery cover 30 and cannot receive the hooks 3111 if the latching member 53 is kept there. When the battery cover 30 presses the pressed portion 131, the latching member 53 is unlocked and moves to allow the hook holes 5333 to receive the hooks 3111. Thus, the latching member 53 is controlled by the pressed portion 131 to automatically lock with the hooks 3111.
Referring to FIG. 9, when the battery cover 30 is to be opened, the button 5311 is pushed with an external force to move toward the first end portion 13 until the projections 5341 are forced to be received in the latching groove 137. The hooks 3111 can then be separated from the hook hole 5333. The pressed portion 131 automatically pushes out the battery cover 30. The battery cover 30 can then be removed.
As described above, the exemplary embodiment provides a battery cover assembly for portable electronic devices, such as mobile phones. The battery cover of the battery cover assembly can be easily opened and more user-friendly.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the disclosure.
