## Title
Battery cover latching assembly

## Abstract

A battery cover latching assembly, detachably securing a battery cover to a housing, includes a button, battery cover, elastic member arranged between the button and the housing, and a resisting member resisting the battery cover away from the housing. The button includes a locking portion. The battery cover includes a corresponding locking member. The locking portion is slidably received in the housing to clamp or release the locking member.

## Background
BACKGROUND
1. Field of the Disclosure
The present disclosure relates to battery housing and, particularly, to a battery cover latching assembly used in a portable electronic device.
2. Description of Related Art
Battery cover latching assemblies are usually provided to secure and allow required access to batteries to portable electronic devices.
A typical battery cover latching assembly for an electronic device usually includes a pair of hooks on one end of a battery cover of the electronic device and a locking pin on the other end of the battery cover. Correspondingly, a pair of grooves is defined in a housing of the electronic device. A locking hole corresponding to the locking pin is also defined in the housing. By attaching the battery cover onto the housing, the hooks can enter into the grooves, and the locking pin is securely latched into the locking hole. Thus, the battery cover is secured to the housing.
However, to detach the battery cover, considerable force is needed due to the tight latching of the locking pin into the locking hole. Thus, the battery cover may be damaged, and it is difficult to replace the locked battery.
Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENT
FIGS. 1 and 2 show an exemplary battery cover latching assembly 10 used in portable electronic devices, such as mobile phone terminals, digital cameras, and others. The battery cover latching assembly 10 includes a housing 11, a battery cover 12, a button 13, two elastic members 14 and two resisting members 15.
The housing 11 includes a front wall 111, a top wall 112, a bottom wall 113, a left sidewall 114 and a right sidewall 115. The front wall 111, the top wall 112, the bottom wall 113, the left sidewall 114 and the right sidewall 115 cooperatively enclose a rectangular battery receiving space 116 seating a battery (not shown) therein. The housing 11 defines a button receiving compartment 117 and a T-shaped cutout 1171 in the front wall 111, and an opening 1172 through the bottom wall 113. The button receiving compartment 117 can be defined by two opposite sidewalls 1173 and a resisting wall 1174. Each sidewall 1173 defines a through hole 1176 (see FIG. 2). The top wall 112 defines two limiting grooves 118 adjacent to the front wall 111.
The battery cover 12 includes a front wall 121 and a back wall 122. A locking member 123 protrudes from an end of the back wall 122. The back wall 122 defines two securing portions 124 on two sides of the locking member 123. The resisting members 15 are fixed, by, for example, threading, to the corresponding securing portions 124. Two limiting blocks 125 correspond to the limiting grooves 118 and protrude outwardly from the periphery of the battery cover 12, opposite to the securing portions 124.
Referring to FIG. 3, the button 13 includes a contact surface 131. The button 13 defines a concave 1331 and thus forms a locking portion 134. The button 13 further includes two hooks 135 protruding away from the contact surface 131 on two sides of the locking portion 134. The hooks 135 elastically interlock in the through hole 1176. Two columns 136 are defined between the hooks 135 and adjacent to the locking portion 134, connecting to an inner surface of the contact surface 131.
Each elastic member 14 may be a coil spring, aligning and engaging the two columns 136 and received in the button receiving compartment 117. One end of each elastic member 14 abuts the resisting wall 1174, and the other end of the elastic member 14 abuts the button 13.
The resisting member 15 is a V-shaped elastic sheet including a first sheet portion 151 and a second sheet portion 152. A repelling force is generated when the angle between the first sheet portion 151 and the second sheet portion 152 is reduced. The first sheet portion 151 is fixed to the battery cover 12. The second sheet portion 152 faces the housing 11 and resists the battery cover 12 away from the housing 11.
Referring to FIGS. 4 and 5, during assembly, the elastic members 14 engage and wrap around the columns 136. The button 13 and the elastic members 14 are inserted into the button receiving compartment 117. The button 13 is further pressed to the resisting wall 1174 until the two hooks 135 interlock into the through hole 1176. At this time, the elastic members 14 are deformably compressed against the resisting wall 1174.
To latch the battery cover 12 to the housing 11, the battery cover 12 is aligned with and pressed downwardly to the housing 11. The limiting blocks 125 are inserted into the limiting grooves 118. The battery cover 12 is pivoted about the housing 11 until the locking member 123 is latched to the locking portion 134. At this time, the resisting members 15 are compressed between the battery cover 12 and the housing 11.
Referring to FIG. 6, to release the battery cover 12, the button 13 is pressed towards the resisting wall 1174 to release the locking member 123 from the locking portion 134. The battery cover 12 then automatically releases upwardly from the housing 11 by the decompression of the resisting members 15.
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.
