1. Technical Field
The present disclosure generally relates to electronic devices, and particularly relates to electronic devices having locking mechanisms.
2. Description of Related Art
Many electronic devices include an enclosure, a cover plate, a battery module, a first locking member, and a second locking member. The enclosure defines an opening. The cover plate is attached to the enclosure and covers the opening of the enclosure. The enclosure further defines a receiving slot for receiving and holding the battery module. The first locking member and the second locking member are mounted to the enclosure and secure the cover plate and the battery module to the enclosure. To disassemble, a user has to first dismantle both the first locking member and the second locking member, and then remove the cover plate and the battery module from the enclosure. It is not convenient for the user. Therefore, there is room for improvement within the art.

Referring to
When mounting the cover plate 20 to the enclosure 10, the cover plate 20 is moved towards the enclosure 10 and the pair of clasping ribs 24 of the cover plate 20 faces the at least one opening 12 of the enclosure 10. When the cover plate 20 is located in an installed position, the second rib portions 243 of the cover plate 20 abut and urge the protrusions 321 of the locking member 30 to move the locking member 30 to the left (assuming the first hook piece 31 of the locking member 30 is at the left and the second hook piece 36 of the locking member is at the right). A left member of the pair of resilient members 60 is compressed and a right member of the pair of resilient members 60 is extended due to the left movement of the locking member 30. When the protrusions 321 go over the second rib portions 243, the pair of resilient members 60 recovers and drives the locking member 30 to move back to the right. The protrusions 321 of the pair of first clasps 32 of the locking member 30 are engaged with the first rib portions 241 of the pair of clasping ribs 24 thereby preventing the cover plate 20 from moving away from the enclosure 10. The plurality of limiting pieces 22 of the cover plate 20 are in contact with the margins of the at least one opening 12. Thus, the cover plate 20 is secured to the enclosure 10 and covers the at least one opening 12 of the enclosure 10.
The pair of resilient clipping tabs 52 of the operating member 50 extends through the rectangular opening 151 of the enclosure 10 and the installation hole 35 of the locking member 30 successively. Thus, the operating member 50 is mounted to the locking member 30 and operable to drive the locking member 30 to move to the left or the right. The plate body 51 of the operating member 50 is slidably mounted to the exterior side surface of the enclosure 10. The wavy operating portion 54 of the operating member 50 facilitates sliding movement of the operating member 50 relative to the enclosure 10.
When installing the battery module 40 to the enclosure 10, the battery module 40 is moved towards and close to the installation slot 14. The slant planes 4231 of two of the blocking tabs 423 of the battery module 40 abut and press a slant plane 341 of each of the pair of second clasps 34 of the locking member 30 to move the locking member 30 to the right until the slant planes 341 of the pair of second clasps 34 go over the slant planes 4231 of two of the blocking tabs 423. The locking member 30 is moved to the left by elastic forces exerted by the pair of resilient members 60 until the pair of second clasps 34 are engaged with two of the blocking tabs 423. Thus, the battery module 40 is fixed in the installation slot 14 of the enclosure 10. During the installation of the battery module 40, the locking member 30 is first moved from an initial position to the right, and then moved from the left back to the initial position by elastic forces exerted by the pair of resilient members 60. The protrusions 321 of the pair of first clasps 32 are moved back and forth along the first rib portions 241 of the cover plate 20, but will not be disengaged from the first rib portions 241 of the cover plate 20. Thus, the cover plate 20 remains secured to the enclosure 10.
When detaching the battery module 40, an acting force is applied to the operating portion 54 of the operating member 50 to actuate the operating member 50 to move the locking member 30 to the right. The pair of second clasps 34 of the locking member 30 is disengaged from two of the blocking tabs 423 and presses two of the resisting portions 421 to drive the battery module 40 to move outwards slightly. Thus, the battery module 40 is unfixed and can be removed from the installation slot 14 of the enclosure 10.
When disassembling the cover plate 20 from the enclosure 10, an acting force is applied to the operating portion 54 of the operating member 50 to actuate the operating member 50 to move the locking member 30 to the left and elastically deform the pair of resilient members 60. When the protrusions 321 of the pair of first clasps 32 of the locking member 30 are disengaged from the first rib portions 241 of the pair of clasping ribs 24 of the cover plate 20, the acting force is released and the pair of resilient members 60 elastically recovers. The locking member 30 is moved to the right by elastic recovery forces exerted by the pair of resilient members 60. The protrusions 321 of the pair of first clasps 32 of the locking member 30 abut and press the second rib portions 243 of the cover plate 20 to drive the cover plate 20 to move outwards. The plurality of L-shaped limiting pieces 22 are disengaged from the enclosure 10. Thus, the cover plate 20 is unfastened and can be removed from the enclosure 10.
In other embodiments, when the battery module 40 is fixed in the installation slot 14 of the enclosure 10 by the pair of second clasps 34 of the locking member 30, the locking member 30 is prevented from moving to the left and unfastening the cover plate 20. When the battery module 40 is unfixed and removable from the enclosure 10, the locking member 30 is allowed to move to the left and unfasten the cover plate. In this way, an ordinary operator is able to avoid performing some improper operations, for example, dismantling the cover plate 20 without first removing the battery module 40.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions 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.
