1. Field of the Invention
The present invention 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 typical battery cover mechanism includes a cover and a housing. The cover includes a pin at on one end and a hook at an opposite end. The housing defines a receiving hole and a holding aperture. The hook can be inserted into the holding aperture, and the cover can be pressed towards the housing until the pin is received into the receiving hole. As such, the cover securely engages with the housing by the hooking of the hook. However, the pin tends to slide out of the receiving hole when exerting a large external force.
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 elastic member 20 includes a fixing portion 22 and a locking portion 24 integrally formed with the fixing portion 22. The fixing portion 22 is generally circular and configured for engaging with the first locking member 12. The locking portion 24 includes two bending strips 242 bending toward the center of the circle, symmetrically about the diameter of the circle and approaching each other. Each of the bending strips 242 includes an arc section 2422 at the middle thereof, the two arc sections 2422 face each other to define a locking space 2424 therebetween.
The housing 30 has an assembling groove 32 and a receiving groove 34 defined. The assembling groove 32 is defined at an end of the housing 30, and the assembling groove 32 has a protrusion 322 protruding near the center. The protrusion 322 is a column to securely engage into the locking space 2424 of the elastic member 20. The receiving groove 34 is defined near the assembling groove 32 and configured for receiving a battery (not shown).
In assembling of the cover 10, the elastic member 20 latched with the locking member 12, the fixing portion 22 can be received the locking recesses 1222 of the first locking members 122, the locking portion 24 can be positioned between the two second locking member 124 by the two bending strips 242 resisting the two second locking member 124 respectively.
Referring to
In the exemplary battery cover mechanism 100, the cover 10 can be installed on the housing 30 through tightly securing of the locking portion 24 with the protrusion 322.
It is to be understood that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of structures and functions of various embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
