## Background
BACKGROUND
1. Technical Field
The present disclosure relates to battery cover latching assemblies 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 of 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, an external force is needed due to the tight latching of the locking pin into the locking hole. Thus, the battery cover may be damaged, which makes it inconvenient to replace the locked battery.
Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION
FIGS. 1 and 2 show an exemplary battery cover latching assembly 100 for portable electronic devices, such as mobile phones, digital cameras and etc. The battery cover latching assembly 100 includes two latching assemblies 10, a battery cover 20, and a body member 30. The latching assemblies 10 are rotatably mounted to the body member 30, configured for releasably latching the battery cover 20 to the body member 30.
Each latching assembly 10 includes a button 12 and an elastic member 14. The button 12 includes a first surface 121 and a second surface 122 opposite to the first surface 121. The first surface 121 is for being pressed. A securing portion 123 protrudes from one end of the button 12. A connecting portion 124 protrudes from an opposite end of the button 12. The securing portion 123 and the connecting portion 124 may be adjacent to the second surface 122. A latch block 125 protrudes from one side of the connecting portion 124 facing the first surface 121. In this embodiment, the latch block 125 is a wedge-shaped block. Referring to FIGS. 2 and 3 together, the latch block 125 includes a wedge-shaped surface 1254 and a latch slot 1252. The wedge-shaped surface 1254 faces away from the latch slot 1252. The latch slot 1252 is defined in a wall of the latch block 125 opposite to the wedge-shaped surface 1254. The battery cover 20 slides into the latch slot 1252 guided by the wedge-shaped surface 1254. A first clamp block 126 protrudes from the other side of the connecting portion 124 opposite to the latch block 125. The first clamp block 126 and the connecting portion 124 define a first clamp space 127 for clamping one end of the elastic member 14.
The elastic member 14 is a waved sheet. One end of the elastic member 14 is latched in the first clamp space 127, the other end of the elastic member 14 is clamped to the body member 30. The elastic member 14 provides a force to rebound the button 12 to an original state.
The battery cover 20 defines a cutout 22, corresponding to the button 12. The button 12 is received in the cutout 22. A stopping block 24 protrudes from an inside of the battery cover 20, adjacent to the cutout 22. The stopping block 24 corresponds to the latch block 125. The stopping block 24 is latched in the latch slot 1252.
The body member 30 defines a receiving cavity 32 to receive a battery (not shown). The receiving cavity 32 is surrounded by two opposite sidewalls 34. Referring to FIGS. 2 and 4 together, each sidewall 34 defines a groove 342, corresponding to the latching assembly 10. The groove 342 is surrounded by a first wall 3421, a second wall 3422, a third wall 3423. The second wall 3422 is opposite to the first wall 3421. The first wall 3421 defines a securing hole 3424 for securing the securing portion 123. The third wall 3423 defines an channel 3425 aligned with the first clamp block 126. The clamp block 126 can be moveably received in the channel 3425. A second clamp block 3426 protrudes from one end of the third wall 3423 adjacent to the first wall 3421 (see FIG. 4). The second clamp block 3426 and the third wall 3423 define a second clamp space 3427, facing the second wall 3422. The second clamp space 3427 clamps the other end of the elastic member 14.
Referring to FIG. 4, during assembly, one end of the elastic member 14 is clamped in the first clamp space 127 of the button 12. The button 12 and the elastic member 14 are inserted into the groove 342. At this time, the securing portion 123 is latched in the securing hole 3424, and the other end of the elastic member 14 is clamped in the second clamp space 3427. Thus, the latching assembly 10 is stably mounted in the body member 30.
To latch the battery cover 20 to the body member 30, the battery cover 20 is positioned over the battery receiving space 32. The battery cover 20 is pressed towards the body member 30. During this stage, each stopping block24 is slid along a corresponding wedge-shaped surface 1254 to push the latch block 125 inwardly. The button 12 is rotated by the stopping block 24 about the securing portion 123 until the first clamp block 126 and the latch block 125 enter into the body member 30. At this time, the first clamp block 126 is received in the channel 3425, and the elastic member 14 accumulates an elastic force. The battery cover 20 is continued to be pressed until the stopping blocks 24 go over the wedge-shaped surface 1254. Then the battery cover 20 is released, and the button 12 is rebounded by the elastic force to drive the stopping blocks 24 to latch into the latch slots 1252.
To release the battery cover 12, the button 12 is pressed to be rotated about the securing portion 123 until the first clamp block 126 and the latch block 125 enter into the body member 30. During this process, the first clamp block 126 is received in the channel 3425, and the elastic member 14 accumulates an elastic force. The button 12 is continued to be pressed until the stopping blocks 24 is completely released from the latch block 125. Thus, a user can easily detach the battery cover 20 from the body member 30.
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.
