1. FIELD OF THE INVENTION
The present invention generally relates to battery cover latching assemblies and, more particularly, to a battery cover latching assembly for use in a portable electronic device.
2. DESCRIPTION OF RELATED ART
Batteries are widely used in portable electronic devices, such as personal digital assistants (PDAs), mobile phones, and the like. Conventional batteries are attachably received in housings of the electronic device, and battery covers are designed to connect with the housings to package the batteries. The batteries have to be replaced by opening the battery covers when the batteries are, e.g., damaged, dead, and/or otherwise in need of recharging or replacement.
A clasping structure or latching structure is used to engage a conventional battery cover with a housing of a portable electronic device. For example, the Alcatel OT310 mobile phone has a latching assembly for a battery cover. The latching assembly includes two hooks at one end of the battery cover and a locking pin protruding from the other end of the battery cover. Two grooves are defined in one end portion of a backside of a housing of the mobile phone, and a locking hole is defined in the other end portion of the backside of the housing. In assembly, the hooks are firstly inserted into the grooves in the backside of the housing. Then, the battery cover is pressed downwards onto the housing until the locking pin on the battery cover is inserted into the locking hole in the backside of the housing. The battery cover is thus assembled to the housing of the mobile phone. The latching assembly is simple in structure, and the engagement between the battery cover and the housing of the mobile phone is firm, too. However, during disassembly, great effort is needed to remove the battery cover, thereby requiring a relatively substantial force to be exerted thereon. Therefore, the battery cover can be susceptible to damage. As a result, it can be difficult for a user to replace a battery in the conventional housing of the mobile phone.
Therefore, a new battery cover latching assembly is desired in order to overcome the above-described shortcomings.
In one embodiment thereof, a portable electronic device has a battery cover, a battery cover latching assembly, and a housing. The housing has a cavity. The battery cover latching assembly includes a latching member, a first magnetic member, and a second magnetic member. The latching member is received in the cavity of the housing and is slidable in a first direction. The first magnetic member is mounted to the latching member. The second magnetic member is mounted to the housing. The second magnetic member cooperates with the first magnetic member to create force acting in the first direction to enable the latching member to mount the battery cover to the housing.
Other advantages and novel features of the embodiments will become more apparent from the following detailed description thereof, when taken in conjunction with the accompanying drawings.
Many aspects of the battery cover latching assembly 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 present battery cover latching assembly and its potential applications. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The present battery cover latching assembly is suitable for portable electronic devices, such as mobile phones, PDAs, and so on.
Referring now to the drawings in detail,
Further referring to
The battery cover 20 is substantially a rectangular board. Two positioning flakes 22 are formed at one end of the battery cover 20. The two positioning flakes 22 are engaged in the two respective positioning holes 114 of the housing 10. A rectangular locking board 24 is formed at an opposite end of the battery cover 20. A central portion of the locking board 24 is bent to define a locking hole or slot 242 therein.
The latching member 30 includes an operation portion 32, a positioning portion 34, and a block 36. The operation portion 32 is a substantially elliptical board in shape. The operation portion 32 defines a hole in one end thereof for ease of pushing. The positioning portion 34 is connected to the operation portion 32. Two outer hooks 342 extend from one end of the positioning portion 34. The two outer hooks 342 face away from each other. Two inner hooks 344 extend from the end of the positioning portion 34 and in a same direction as the outer hooks 342. The two inner hooks 344 face towards each other. The block 36 is formed at a joint between the operation portion 32 and the positioning portion 34. The block 36 is substantially wedge-like in shape.
The first magnetic member 40 and the second magnetic member 50 can be permanent magnets. The first magnetic member 40 has a T-shaped cross-section and is configured for being received between the two inner hooks 344 of the latching member 30. A first end of the first magnetic member 40 is exposed from the inner hooks 344. The second magnetic member 50 has a T-shaped cross-section and is configured for being received in the notch 192 of the housing 10. A second end of the second magnetic member 50 is exposed out of the notch 192. The first end of the first magnetic member 40 and the second end of the second magnetic member 50 have identical polarity.
In assembly, the first magnetic member 40 is mounted between the two inner hooks 344 of the latching member 30. The first end of the first magnetic member 40 is exposed from between the inner hooks 344. The second magnetic member 50 is mounted in the notch 192 of the housing 10. The second end of the second magnetic member 50 is exposed out of the notch 192. The positioning portion 34 of the latching member 30 travels through the cavity 16. Each of the outer hooks 342 engages with a corresponding positioning hook 18, and the latching member 30 is thereby mounted on the housing 10. The operation portion 32 is exposed out from the outer surface 134. The block 36 is pushed away from the second magnetic member 50 due to force acting between the first magnetic member 40 and the second magnetic member 50. The first end of the first magnetic member 40 faces towards the second end of the second magnetic member 50. Thus, the battery cover latching assembly 80 is assembled in the housing 10 and is slidable in a horizontal direction.
When the battery cover 20 is assembled to the housing 10, the positioning flakes 22 of the battery cover 20 are received in the positioning holes 114 of the housing 10. The opposite end of the battery cover 20 is pressed down onto the housing 10. When the locking board 24 touches the block 36, the battery cover 20 is held down and the block 36 and then the latching member 30 are moved away from the battery cover 20 by the locking board 24. When the block 36 faces towards the locking slot 242, the block 36 is moved into the locking slot 242 due to the force acting between the first magnetic member 40 and the second magnetic member 50. Thus, the battery cover 20 is assembled with the housing 10, as represented in
When the battery cover 20 is to be detached from the housing 10, the operation portion 32 of the latching member 30 is manually moved away from the battery cover 20. The block 36 of the latching member 30 correspondingly moves out of engagement with the locking slot 242 of the battery cover 20. The battery cover 20 is pulled away from the housing 10 manually. By releasing the operation portion 32, the block 36 is moved away from the second magnetic member 50 due to the force from the first magnetic member 40 and the second magnetic member 50.
It is to be understood that the battery cover 20 may have a block formed at one end thereof. The latching member 30 may defined a locking slot therein for receiving the block of the battery cover 20.
It is to be understood, however, that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, 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 invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
