## Background
BACKGROUND
1. Technical Field
The exemplary embodiment generally relates to sliding-type portable electronic devices, and particularly to sliding-type portable electronic device that can slide automatically.
2. Description of Related Art
Sliding mechanisms are widely used in portable electronic devices, such as mobile phones and personal digital assistants (PDAs). A typical sliding mechanism usually includes a sliding member, a fixable member and a resilient member. The sliding member is slidably mounted on the fixable member. The resilient member is used to drive the sliding member to slide and/or return the moved sliding member to its initial position. In use, the sliding mechanism is assembled in a portable electronic device including a base and the cover, the fixable member is fixed to the base and the sliding member is fixed to the cover. Thus, the cover can slide back and forth to slide on the base, and covers or exposes keypad(s) mounted on the base.
However, in use of the typical sliding mechanism, the resilient member generally cannot automatically drive the sliding member and the cover to move to predetermined positions. Thus, the portable electronic device using the typical sliding mechanism cannot be conveniently used.
Therefore, there is room for improvement within the art.

The connecting rod mechanism 32 includes a sliding element 322, a first connecting rod 324, and a second connecting rod 326. One end of the first connecting rod 324 is connected to the sliding element 322, the other end of the first connecting rod 324 is hinged to second connecting rod 326. The controlling mechanism 34 includes a sliding block 342, a first elastic element 344, a second elastic element 346, and a button 348. The sliding block 342 is located between the second elastic element 346 and the button 348. The first elastic element 344 provides an elastic force for driving the second connecting rod 326 to rotate.
The sliding element is substantially pole shaped. One end of the sliding element 322 is secured to the cover 10, and the other end of the sliding element 322 is slidably mounted to the base 20. In this embodiment, the sliding element 322 may be secured to the cover 10 by the following means: the cover 10 defines a hole 12 (referring to FIG. 3) for securely (e.g., holt-melted) accommodating one end of the sliding element 322. The manner of slidably mounting the other end of the sliding element 322 to the base 20 will be described hereinafter.
The first connecting rod 324 has a first mating opening 3242 and a second mating opening 3244 respectively defined in two opposite ends thereof. The first mating opening 3242 is configured to accommodate a center portion of the sliding element 322 so that the sliding element 322 is mounted on the first connecting rod 324. The second mating opening 3244 is configured for hinging to the second connecting rod 326. The second connecting rod 326 has a first mating pole 3262 protruding from one end thereof. The first mating pole 3262 is rotatably accommodated in the second mating opening 3244, so that the first connecting rod 324 is hinged to the second connecting rod 326. The second connecting rod 326 has a third mating opening 3264 defined at another end thereof. The third mating opening 3264 is configured to rotatably engage with the base 20. The second connecting rod 326 has a latching pole 3268 (See FIG. 3) protruding from a surface 3266 thereof facing the base 20, and the latching pole 3268 is located adjacent to the third mating opening 3264.
The sliding block 342 is arcuate and has a first latching ribbing 3422 and a second latching ribbing 3424 longitudinally protruding from an inner surface thereof. The first latching ribbing 3422 is spaced from the second latching ribbing 3424. When the portable electronic device is in a closed state, the latching pole 3268 is latched to the first latching ribbing 3422 (See FIG. 5). When the portable electronic device is in an open state, the latching pole 3268 is latched to the second latching ribbing 3424 (See FIG. 7). Referring to FIG. 3, the sliding block 342 has two spaced guiding poles 3426 protruding from one side thereof facing the base 20. The guiding poles 3426 are configured to guide the sliding block 342 to slide relative to the base 20.
Referring to FIGS. 2 and 3, the first elastic element 344 provides an elastic force for rotating the second connecting rod 326 relative to the base 20. The second elastic element 346 provides an elastic force for restoring the sliding block 342 to its original state. In this embodiment, the first elastic element 344 is a columnar coil, and the second elastic element 346 is a columnar compression spring. The first elastic element 344 has a securing ring 3442 protruding outwardly from one end thereof and a hook 3444 protruding outwardly from another end thereof. The second elastic element 346 is held between the sliding block 342 and the base 20, i.e., one end of the second elastic element 346 is resisted against the sliding block 342, another end of the second elastic element 346 is resisted against the base 20. The button 348 has an operating portion 3482 protruding from one side thereof and two spaced contacting portions 3484 protruding from another side thereof opposite to the operating portion 3482, so that two flanges 3486 are formed at two opposite ends of the button 348. The contacting portions 3484 correspond to two ends of the sliding block 342 and are configured for contacting the sliding block 342.
The base 20 includes a top surface 22 and a side surface 24 connected to the top surface 22. The base 20 has a compartment 222 defined in the top surface 22 corresponding to the controlling mechanism 34 and a sliding groove 224 longitudinally defined in the top surface 22 corresponding to the sliding element 322. The compartment 222 is defined through the side surface 24, so a bottom wall 2220, a first inner wall 2221 parallel to the side surface 24 of the base 20, and two opposite second inner walls 2222 connected to the side surface 24 are defined in the compartment 222. The sliding groove 224 is configured to slidably accommodate the sliding element 322.
The base 20 has a second mating pole 2223 protruding from the bottom wall 2220 corresponding to the third mating opening 3264, a first retaining pole 2224 protruding from the bottom wall 2220 adjacent to the second mating pole 2223, and two guiding grooves 2225 (see FIG. 5 and FIG. 7) defined in the bottom wall 2220 corresponding to the guiding poles 3426 of the sliding block 342. The second mating pole 2223 is rotatably accommodated in the third mating opening 3264. The securing ring 3442 of the first elastic element 344 is wound on the first retaining pole 2224 to secure the first elastic element 344 on the base 20. The guiding grooves 2225 are configured to slidably accommodate the guiding poles 3426 therein.
The base 20 has a second retaining pole 2226 protruding from the first inner wall 2221. The second retaining pole 2226 is configured to secure the second elastic element 346 to the base 20. The base 20 has two slots 2227 defined in the second inner wall corresponding to the flanges 3486 of the button 348. The flanges 3486 are slidably accommodated in the slots 2227.
Referring to FIGS. 4 and 5, during assembly of the portable electronic device 100, firstly, the second elastic element 346 is wound around the second retaining pole 2226. Secondly, the sliding block 342 is received in the compartment 222. At this time, the guiding poles 3426 are correspondingly accommodated in the guiding grooves 2225, and the second elastic element 346 is twisted to accumulate elastic force. The first elastic element 344 is wound to the second mating pole 2223. At this time, the securing ring 3442 is retained on the first retaining pole 2224. Then, the button 348 is put into the compartment 222 with the flanges 3486 of the button 348 being accommodated in the slots 2227 of the base 20. At this stage, the contacting portions 3484 of the button 348 resist against the two ends of the sliding block 342. The first mating pole 3262 is rotatably accommodated in the second mating opening 3244 to hinge the first connecting rod 324 to the second connecting rod 326.
After that, the second mating pole 2223 is rotatably accommodated in the third mating opening 3264 of the second connecting rod 326, i.e., the second connecting rod 326 is hinged to the base 20. The hook 3444 of the first elastic element 344 is secured to the second connecting rod 326 to connect the connecting rod mechanism 32 to the controlling mechanism 34. The center portion of the sliding element 322 is secured (e.g., hot-melted) in the first mating opening 3242, to fix the sliding element 322 to the first connecting rod 324. The end portion of the sliding element 322 facing the base 20 is slidably accommodated in the sliding groove 224 of the base 20, and another end portion of the sliding element 322 facing the cover 10 is secured in the hole 12 of the cover 10.
Finally, the cover 10 is slid relative to the base 20 to make the latching pole 3268 latch with the first latching ribbing 3422. At this time, the portable electronic device 100 is in a closed position, the sliding element 322 is located in one end of the sliding groove 224, and the first elastic element 344 is counterclockwise twisted to provide a clockwise elastic force to the second connecting rod 326. Thus, the second connecting rod 326 tends to rotate clockwise.
Referring to FIGS. 6 and 7, in use, pressing the operating portion 3482 of the button 348, the contacting portions 3484 biases the sliding block 342 to slide in the compartment 222 with the guiding poles 3426 slides in the guiding grooves 2225 of the base 20 and the second elastic element 346 is compressed to accumulate elastic force, until the first latching ribbing 3422 is released from the latching pole 3268 of the second connecting rod 326. At this time, the sliding block 342 is restored to its original state under the elastic force of the second elastic element 346. The second connecting rod 326 is clockwise rotated under the elastic force of the first elastic element 344, which drives the first connecting rod 324 to rotate clockwise and further drives the sliding element 322 to slide toward another end of the sliding groove 224. Additionally, the sliding element 322 is fixed to the cover 10, so the cover 10 slides relative to the base 20 at this time.
Once the sliding element 322 is slid to another end of the sliding groove 224, the cover 10 is in an open state. At this time, the latching pole 3268 is latched to the second latching ribbing 3424, and the second connecting rod 326 is under clockwise pressure, so that the cover 10 is securely located in the opened state.
When closing the cover 10 again, the cover 10 is reversely pushed with the sliding element 322 sliding in the sliding groove 224, until the sliding element 322 reaches its original state. At this time, the latching pole 3268 is latched to the first latching ribbing 3422 again, so the cover 10 is securely located in the closed position.
Once the button 348 is pressed, the sliding mechanism 30 can automatically drive the cover 10 to move to predetermined positions. Thus, the portable electronic device using the sliding mechanism 30 can be conveniently used.
