## Background
BACKGROUND
1. Technical Field
The present disclosure relates to battery cover latching mechanisms and, particularly, to a battery cover latching mechanism used in a portable electronic device.
2. Description of Related Art
Batteries are used to provide power to portable electronic devices, e.g., mobile phones. Battery cover latching assemblies are usually provided to secure battery within portable electronic devices.
A typical battery cover latching assembly for an electronic device usually includes a battery cover and latching means, e.g., a locking pin latching into a locking hole. The battery cover can be detachably mounted to a housing of portable electronic devices using the latching means.
However, removal of the battery cover may require a strong force, which may damage the locking pin.
Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION
FIG. 1 shows an exemplary battery cover latching mechanism 100 including a body member 10, a battery cover 20, and a button assembly 30. The battery cover 20 is placed on the body member 10. The button assembly 30 is rotatably attached to the body member 10, and is used to releasably lock the battery cover 20 to the body member 10.
The body member 10 can be a housing of a portable electronic device. The body member 10 includes a top portion 11, a bottom portion 12 opposite to the top portion 11, and two opposite sidewalls 13. The two sidewalls 13 connect the top portion 11 and the bottom portion 12 to surround a battery receiving space 14. The top portion 11 defines two first limiting slots 111 communicating with the battery receiving space 14. The top portion 11 further includes a cavity 15 defined between the two limiting slots 111, communicating with the battery receiving space 14. The cavity 15 is defined by a bottom wall 151 and a sidewall 152. The body member 10 further includes two latching protrusions 16 protruding from the bottom wall 151. The two latching protrusions 16 are parallel and a latching slot 161 is defined therebetween. In this embodiment, the latching slot 161 includes a pivoting slot 1611 and an inserting slot 1612 communicating with the pivoting slot 1611. The pivoting slot 1611 is used to rotatably attach the button assembly 30 to the body member 10. A width of the inserting slot 1612 is smaller than the pivoting slot 1611. The inserting slot 1612 is a narrow opening, through which the button assembly 30 is inserted into the pivoting slot 1611. The sidewall 152 defines a concave surface 1521. The concave surface 1521 facilitates catching the button assembly 30 received in the cavity 15. The bottom portion 12 of the body member 10 includes two second limiting slots 121 defined therein facing away from the battery receiving space 14.
The battery cover 20 is used to enclose the battery receiving space 14. The battery cover 20 includes a main section 21, a first end 22, an opposite second end 23, and two opposite sidewalls 24. The main section 21 includes a clamping portion 211. The main section 21 is partially recessed adjacent to the first end 22 to form the clamping portion 211 for latching the battery cover 20 to the body member 10. Two tabs 212 are formed on the main section 21 adjacent to the first end 22, and are used to insert into the first limiting slots 111. Two limiting blocks 213 are formed on the main section 21 adjacent to the second end 23, and are used to insert into the second limiting slots 121.
Referring to FIGS. 1 and 2 together, the button assembly 30 includes a connecting member 31 and a button 32. In this embodiment, the connecting member 31 is a pivoting shaft, and the pivoting shaft 31 is generally a bent bar. The pivoting shaft 31 includes a head portion 311, a first connecting portion 312, a mounting portion 313, a second connecting portion 314, and a tail portion 315. The first connecting portion 312 is parallel with the second connecting portion 314. The mounting portion 313 perpendicularly connects one end of the first connecting portion 312 and one end of the second connecting portion 314 together, forming a U-shaped shelf. The head portion 311 perpendicularly connects to the other end of the first connecting portion 312. The tail portion 315 perpendicularly connects to the other end of the second connecting portion 314 towards the head portion 311. The mounting portion 313 is rotatably received in the pivoting slot 1611 through the inserting slot 1612. The head portion 311 and the tail portion 315 are rotatably mounted to the button 32, such that the button 32 can rotate about the head portion 311 and the tail portion 315. Thus, the pivoting shaft 31 can rotate about the mounting portion 313 together with the button 32. The button 32 includes a latching portion 321 formed at one end thereof, and two ribs 322 formed at an opposite end. Each rib 322 defines a pivoting hole 3221. The two pivoting ribs 322 are opposite to each other, and the two pivoting holes 3221 are coaxial. The head portion 311 and the tail portion 315 are respectively inserted into a pivoting hole 3221. The button 32 defines a notch 323. The notch 323 is arced and cooperates with the concave surface 1521 to facilitate catching the button assembly 30.
Referring to FIG. 3, to mount the button assembly 30 to the body member 10, the head portion 311 and the tail portion 315 of the pivoting shaft 31 are respectively inserted into one pivoting hole 3221 of the button 32. Then the mounting portion 313 of the pivoting shaft 31 is inserted into the pivoting slot 1611. Thus, the button 32 can rotate about the head portion 311 and the tail portion 315. The pivoting shaft 31 can rotate about the mounting portion 313.
Referring to FIGS. 4 and 5, to mount the battery cover 20 to the body member 10, the battery cover 20 is generally placed over the battery receiving space 14, with the first end 22 facing the top portion 11 of the body member 10. The battery cover 20 is pushed towards the top portion 11 until the tabs 212 latches into the first limiting slots 111, and the limiting blocks 213 latch into the second limiting slots 121. Then, the button 32 is rotated about the head portion 311 and the tail portion 315, i.e., a first axis, and the pivoting shaft 31 is rotated about the mounting portion 313, i.e., a second axis to make the latching portion 321 goes over the clamping portion 211. At this time, the ribs 322 of the button 32 expose out of the cavity 15. The ribs 322 are pressed towards the cavity 15, until the latching portion 321 tightly abuts against the clamping portion 211, thus the battery cover 20 is tightly locked to the body member 10.
To release the battery cover 20 from the body member 10, the pivoting shaft 31 is rotated about the mounting portion 313 until the latching portion 321 is separated from the clamping portion 211. Then the battery cover 20 is pushed towards the bottom portion 12 of the body member 10 until the tabs 212 are released from the first limiting slots 111, and the limiting blocks 213 are released from the second limiting slots 121.
The battery cover latching mechanism 100 can tightly lock the battery cover 20 to the body member 10 using the button assembly 30, and also facilitating opening operation of the battery cover 20 without any breakage.
It is to be understood, however, that even through numerous characteristics and advantages of the present disclosure 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 sections 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.
