DETAILED DESCRIPTION

The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to FIG. 1, a mobile terminal 100 comprises a base body 10, a pair of slidable bodies 20 and a pair of switch mechanisms 30. In an exemplary embodiment, the mobile terminal 100 may be but not limited to a mobile phone, a personal digital assistant (PDA), a digital information appliance, for example. The pair of slidable bodies 20 are slidably mounted to the base body 10. The pair of switch mechanisms 30 are disposed on the pair of slidable bodies 20 respectively and used to lock the pair of slidable bodies 20 to the base body 10 in an open position and a closed position.
The base body 10 defines two pairs of slidable grooves 12 and the base body 10 comprises two pairs of fixing blocks 14. The two pairs of slidable grooves 12 are located on two sidewalls 11 of the base body 10 and extend from a middle part towards two opposite ends of the base body 10 respectively. Each of the slidable grooves 12 defines an opening end 121, where one corresponding of the fixing blocks 14 is fixed.
The base body 10 further defines a pair of base positioning slots 16 located close to the middle part of the base body 10 and a pair of slidable positioning slots 18 located close to the two opposite ends of the base body 10 respectively.
The pair of slidable bodies 20 slide related to the base body 10 towards two opposite directions. Each of the slidable bodies comprises a base 22 and an enclosure 24. Each of the enclosures 24 mounted to the base 22 defines a receiving hole 246. Each of the base 22 comprises a pair of slidable blocks 222 received in the corresponding pair of the slidable grooves 12 to slidably mount the corresponding slidable body 20 to the base body 10. The fixing blocks 14 are fixed in the opening ends 121 of the two pairs of slidable grooves 12 to prevent the pair of slidable bodies 20 separate from the base body 10.
In this embodiment, the base 22 defines a receiving room 221. The two pairs of slidable blocks 222 are protruding from the base 22 towards into the receiving room 221. The two sidewalls 11 of the base body 10 are received in the receiving room 221.
Referring to FIG. 2 and FIG. 3, each of the pair of switch mechanisms comprises a housing 34, a cover 32, an operating member 36, a locking member 38 and a spring unit 35. The housing defines an opening 342 towards the base body 10, a pair of locking grooves 344 and a passing groove 346. The cover 32 is fixed to the housing 34 and covers the opening 342. The cover 32 defines a through hole 322 and comprises a pair of hooks 324 engageable with the locking grooves 344 to fix the cover 32 to the housing 34. The operating member 36 passes through the passing groove 346, and comprises a coupling portion 361 received in the housing 34 and an operating cap 363 extending outwardly from the housing 34 through the passing groove 346. The coupling portion 361 comprises a base bevel 362. That is, the base bevel 362 and the operating cap 363 are respectively defined at two opposite edges of the operating member 36. The operating cap 363 is on outer surface of the mobile terminal 100 and can be used as an operating instrument for a user. That is, the operating cap 363 can be designed as a switch of the mobile terminal 100 and be pressed by a user to drive the base bevel 362 to move.
The locking member 38 is received in the housing 34 and comprises a sliding bevel 382 opposite to and collaborating with the base bevel 362, and a locking block 384 passing through the through hole 322 in the cover 32 to engage with the base body 10 so as to position the corresponding slidable body 20 to the base body 10. When the locking blocks 384 are engaged with the base positioning slots 16, the slidable bodies 20 are positioned at a closed position. When the locking blocks 384 are engaged with the slidable positioning slots 18, the slidable bodies 20 are positioned at an open position.
The spring unit 35 urges between the locking member 38 and the housing 34. In this embodiment, the spring unit 35 comprises a pair of compression springs. The housing 34 defines a pair of recesses 345 to locate the pair of compression springs respectively. One ends of the compression springs are positioned in the recesses 345, and the other ends of the compression springs urge against the locking member 38.
When the operating member 36 is pressed towards the housing 34, the base bevel 362 of the operating member 36 engages with the sliding bevel 382 to drive the locking member 38 move perpendicularly to the operating member 36 as well as compress the spring unit 35, thereby the locking block 384 disengaging from the base body 10 and the corresponding slidable body 20 can slide related to the base body 10.
The switch mechanisms 30 are secured between the bases 22 and the enclosures 24 of the slidable bodies 20. The operating caps 363 of the operating members 36 pass through the receiving holes 246 of enclosures 24 for user's operation.
In this embodiment, the mobile terminal 100 further comprises two pairs of cushions 40 surrounding the two pairs of slidable blocks 222 respectively, and located between the slidable grooves 12 and the slidable blocks 222 to protect the slidable blocks 222 from abrasion.
Referring to FIG. 4, an assembled perspective view of the mobile terminal in open position is shown. In this position, one of the slidable bodies 20 is at the closed position, and the other is at the open position.
Referring to FIG. 5, the pair of slidable bodies 20 attach to each other at the closed position. In this position, the locking blocks 384 are received in the base positioning slots 16, and the mobile terminal 100 has a small size. In use, the user presses the operating caps 363 of the operation members 36 to make the slidable bodies 20 disengage from the base body 10, and slides the slidable bodies 20 towards two opposite ends of the base body 10. When the slidable bodies 20 arrive the two opposite ends of the base body 10 respectively, the locking blocks 384 meet the slidable positioning slots 18, and the locking blocks 384 move into the slidable positioning slots 18 under elasticity of the spring unit 35, so that the pair of slidable bodies 20 are fixed at the open position, as shown in FIG. 6.
In the embodiment, the slidable bodies 20 slide related to the base body 10 via engagement between the slidable blocks 222 and the slidable grooves 12 without any other slidable mechanisms. Therefore, the mobile terminal 100 has a simple structure.
Although the features and elements of the present disclosure are described as embodiments in particular combinations, each feature or element can be used alone or in other various combinations within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
