Abstract
Description
- 1. Technical Field
- The present disclosure relates to cover latching mechanisms, and particularly to a cover latching mechanism of portable electronic devices.
- 2. Description of Related Art
- Portable electronic devices often include latches for securing battery covers thereof. The latch mechanisms must withstand numerous installations and removals of batteries.
- A typical cover latch mechanism includes at least one spring to facilitate its operation. However, the spring can wear out with repeated operation and, thus the cover latch mechanism may eventually fail.
- Therefore, there is room for improvement within the art.
- Many aspects of the new cover latching mechanism can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the new cover latching mechanism. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
-
FIG. 1 is an exploded, isometric view of a cover latching mechanism according to an exemplary embodiment, including a housing member, a cover member and a button assembly. -
FIG. 2 is similar toFIG. 1 , but showing another aspect. -
FIG. 3 is a cut-away assembled view of the cover latching mechanism shown inFIG. 1 , the cover latching mechanism in a latched position. -
FIG. 4 is similar toFIG. 3 , but showing the cover member in a state of removal from the housing member. -
FIGS. 1 and 2 show an exemplarycover latching mechanism 10 for portable electronic devices including ahousing member 11, acover member 12, and abutton assembly 13. Thecover member 12 can be detachably assembled to thehousing member 11 by thebutton assembly 13. - The
housing member 11 includes afirst wall 111, an oppositesecond wall 112, athird wall 113, and abottom wall 114. Thefirst wall 111,second wall 112,third wall 113, andbottom wall 114 cooperatively enclose anaccommodating space 115. Thethird wall 113 defines afirst notch 116 adjacent to thesecond wall 112. Thefirst notch 116 is used to receive part of thebutton assembly 13. Thebottom wall 114 has twopositioning columns 117 protruding inside theaccommodating space 115 near thefirst notch 116. Thefirst wall 111 and thesecond wall 112 have twoopposite latching blocks 118 arranged inside theaccommodating space 115. Thelatching blocks 118 define two throughlatching holes 1181, respectively. - The
cover member 12 can be used to cover theaccommodating space 115. Thecover member 12 includes afirst cover wall 121, an oppositesecond cover wall 122, athird cover wall 123, and atop cover wall 128. Thethird cover wall 123 defines asecond notch 124 adjacent to thesecond cover wall 122. Thesecond notch 124 can align above thefirst notch 116 and receive part of thebutton assembly 13. - An L-
shaped latching hook 125 projects from thetop cover wall 128 adjacent to thesecond notch 124. Thelatching hook 125 has a wave-shapedelastic sheet 126 attached towards thesecond notch 124. Thefirst cover wall 121 and thesecond cover wall 122 have two opposite L-shaped latching protrusions 127 formed for latching into thelatching holes 1181. - The
button assembly 13 includes astepped button member 131 having anexterior surface 1311, aninterior surface 1312, and two stepped resistingribs 1314 connecting theexterior surface 1311 to theinterior surface 1312. Theinterior surface 1312 has a deformable L-shapedlatching jaw 1315 for latching to thelatching hook 125 of thecover member 12. Theinterior surface 1312 further has two elastic resistingarms 132 below thelatching jaw 1315, which extend outwardly from theinterior surface 1312 and away from each other. Each of the resistingarms 132 includes anarm portion 1321 and aannular portion 1322 extending from a distal end of thearm portion 1321. Eachannular portion 1322 defines apositioning hole 1323. - Referring further to
FIG. 3 , after assembly of thebutton assembly 13 to thehousing member 11, thebutton assembly 13 is partially received in thefirst notch 116 and thesecond notch 124 with its resistingrib 1314 resisting thethird wall 113, itsexterior surface 1311 exposed to the outside, and itslatching jaw 1315 and resistingarms 132 received inside theaccommodating space 115. The resistingarms 132 are secured to thebottom wall 114 by, for example, hot-melting thepositioning columns 117 into thecorresponding positioning holes 1323. - Referring again to
FIG. 3 , to latch thecover member 12 to thehousing member 11, thelatching protrusions 127 are extended through and engaged in thelatching holes 1181. Thecover member 12 is pressed towards thehousing member 11. Meanwhile, theelastic sheet 126 is compressed by theinterior surface 1312 and thelatching hook 125 is latched by thelatching jaw 1315. At this time, theelastic sheet 126 and thelatching hook 125 are positioned between thelatching jaw 1315 and theinterior surface 1315. - Referring to
FIG. 4 , to release the cover member, when theexterior surface 1311 is pressed inwardly, thebutton assembly 13 overcomes the elastic force of theelastic sheet 126 and the resistingarms 132 and moves further into theaccommodating space 115. Meanwhile, thelatching hook 125 gradually separates from thelatching jaw 1315. When thelatching hook 125 is completely separated from thelatching jaw 1315, thecover member 12 can be lifted up and removed from thehousing member 11. When the pressing is ceased, the resistingarms 132 return to their original positions and thus thebutton assembly 13 restores to its assembled position. Also upon cessation of the pressing, the restoring member 33 and the arm portion 317 return to their original positions and thus the button assembly 30 restores to its assembled position. - It is to be understood, however, that even through numerous characteristics and advantages of exemplary embodiments have been set forth in the foregoing description, together with details of the structure and function of the 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 disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
