1. Technical Field
The present disclosure relates to battery cover latch mechanisms used in portable electronic devices.
2. Description of Related Art
Portable electronic devices usually include latch mechanisms to latch battery covers to housings. The latch mechanisms are required to allow frequent installation and removal of batteries.
A typical latch mechanism includes a pair of hooks at one end of the battery cover and a locking pin protruding from the other end of the battery cover. The housing defines a pair of grooves and a locking hole. In assembly, the hooks are inserted into the grooves. The battery cover is pressed down to the housing until the locking pin is inserted into the locking hole. However, during disassembly, a large force is needed to remove the battery cover from the housing. Therefore, it can be inconvenient to install or remove a battery.
Therefore, there is room for improvement within the art.
Many aspects of the battery cover latch mechanism and portable electronic device using the battery cover latch 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 battery cover latch mechanism and portable electronic device using the battery cover latch mechanism.
Referring to
The cover member 20 includes a bottom wall 21 and a peripheral wall 22 extending around the peripheral edge of the bottom wall 31. A mounting portion 23 is disposed at one end of the bottom wall 21 to assembly the latching member 30, corresponding to the protruding block 12. The mounting portion 23 includes two opposite side walls 231 and a connecting arm 232. The two side walls 231 protrude from the bottom wall 21. The connecting arm 232 perpendicularly connects one end of each side wall 231 and forms an opening 233 with the bottom wall 21 therebetween. A resisting bar 24 is disposed at the bottom wall 21 and is substantially parallel to and spaced from the connecting arm 232. A matching edge 221 protrudes from edges of peripheral wall 22 and mates with the mounting edge 11 of the housing member 10. The peripheral wall 22 defines a notch 222 in one end thereof to partially receive the latching member 30.
The latching member 30 includes a main portion 31, a contact panel 32, a curled resilient arm 33, two latching clasps 34 and a fixed stopper 35. The main portion 31 is generally a rectangular sheet. The contact panel 32 is disposed at one side of the main portion 31 and corresponds to the notch 222 of the cover member 20. The resilient arm 33 is disposed at another side of the main portion 31 and is opposite to the contact panel 32. The two latching clasps 34 protrude from one surface of the main portion 31 facing the housing member 10, and are configured to engage in the latching holes 14. The fixed stopper 35 protrudes from one edge of the main portion 31 opposite to the contact panel 32 and coplanar with the latching clasps 34.
Referring to
To remove the cover member 20 from the housing member 10, the contact panel 32 is pressed to slide it further into the notch 222. During this stage, the resisting bar 24 deforms the resilient arm 33. Simultaneously, the latching clasps 34 separate from the latching surfaces 141 of the housing member 10. Then, the cover member 20 can be easily detached from the housing member 10 by removal of the latching clasps 34 from the latching holes 14. After release of the contact panel 31, the deformed resilient arm 35 returns to its relaxed state.
The cover member 30 can be attached/detached from the housing member 10 by the operation of the battery cover latch mechanism 100, which is simple in structure and easy to operate.
It is believed that the exemplary embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
