DETAILED DESCRIPTION OF THE INVENTION
The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.
FIG. 2 is a structural schematic diagram showing a portable electronic device 2 of a preferred embodiment of the invention; FIG. 3 is an exploded schematic diagram showing a part of the portable electronic device 2.
As shown in FIG. 2 and FIG. 3, in the embodiment, the portable electronic device 2 includes a first body 21, a second body 22, a guiding assembly 23, a first elastic element 24, a connecting part 25 and a clipping assembly 26. The first body 21 and the second body 22 are adjacently provided.
As shown in FIG. 3, the first body 21 has a track portion 211 and a protrudent block 212. The track portion 211 and the protrudent block 212 may be located at the shorter side or the longer side of the first body 21. The disposing position also may be adjusted according to the actual condition. In the embodiment, the track portion 211 and the protrudent block 212 are disposed at the shorter side. The track portion 211 may be a guiding groove (as shown in FIG. 3) or a guiding block (not shown).
As shown in FIG. 3, the second body 22 has a fastening part 221, a plug 222 and a third elastic element 223. The plug 222 passes through a hole 2211 of the fastening part 221 to pivotally provide the fastening part 221 at the second body 22. The two ends of the third elastic element 223 are against a first end 221a of the fastening part 221 and the second body 22, respectively, to allow the fastening part 221 to rotate with the plug 222 as the axis. Herein, the third elastic element 223 may be an extension spring, a compression spring, an elastic sheet or a telescopic sleeve.
In the embodiment, the second body 22 further has a recessed portion 224. When the first body 21 rotates relatively to the second body 22, the recessed portion 224 can provide a route to allow the first body 21 to rotate relatively to the second body 22 more smoothly.
As shown in FIG. 3, the guiding assembly 23 in the embodiment has a sliding rod 231, a guiding part 232 and a second elastic element 233. In the embodiment, the two ends of the sliding rod 231 are fixed at the first body 21, respectively, and the sliding rod 231 passes through a first through hole 2321 of the guiding part 232 to allow the guiding part 232 to slide along the sliding rod 231.
The guiding part 232 may fasten with the fastening part 221 to limit the relative positions of the first body 21 and the second body 22. That is, when the guiding part 232 fastens with the fastening part 221, the first body 21 cannot rotate relatively to the second body 22.
The second elastic element 233 is jacketed on the sliding rod 231, and the two ends of the second elastic element 233 are against the first body 21 and the guiding part 232, respectively. The second elastic element 233 may be a compression spring. The second elastic element 233 also may be an extension spring, an elastic sheet or a telescopic sleeve. The second elastic element 233 provides an elastic potential energy to allow the first body 21 to slide relatively to the second body 22.
Two ends of the first elastic element 24 are against the first body 21 and the second body 22, respectively, and the first elastic element 24 is held in a recess 225 of the second body 22 adjacent to the fastening part 221. The first elastic element 24 may be a torsion spring, or a torsion elastic sheet. When the guiding part 232 doesn't fasten with the fastening part 221, the first elastic element 24 provides a force to allow the first body 21 to rotate relatively to the second body 22. In addition, as shown in FIG. 3, the connecting part 25 of the embodiment is fixed at the second body 22, and it has a sliding portion 251 and a pivot 252.
In the embodiment, the connecting part 25 is fixed at the position adjacent to the recessed portion 224. The sliding portion 251 and the track portion 211 are slidingly connected to each other. That is, the sliding portion 251 is slidingly disposed at the track portion 211 to allow the first body 21 to slide relatively to the second body 22. When the first body 21 slides relatively to the second body 22, the sliding portion 251 can reinforce the limitation and guide the sliding direction of the first body 21 relative to the second body 22.
The pivot 252 passes through a second through hole 2322 of the guiding part 232 to allow the guiding part 232 and the connecting part 25 to pivotally connected to each other. Thus, the first body 21 may rotate relatively to the second body 22.
For example, when the guiding part 232 slides along the sliding rod 231, the guiding part 232 is connected to the connecting part 25 via the pivot 252 to allow the first body 21 to slide relatively to the second body 22. When the guiding part 232 slides to the fastening part 221, it makes the guiding part 232 fasten with the fastening part 221. Or it makes the guiding part 232 further slides to the protrudent block 212 to allow the protrudent block 212 to move the fastening part 221 to separate from the guiding part 232. When the first body 21 slides relatively to the second body 22, the first elastic element 24 deforms to get an elastic potential energy (not shown). When the protrudent block 212 moves the fastening part 221 to separate from the guiding part 232, the elastic potential energy of the first elastic element 24 releases to allow the first body 21 to rotate relatively to the second body 22 by the pivot 252. Thus, an angle is formed between the first body 21 and the second body 22 (not shown).
As shown in FIG. 3, the connecting part 25 further has a passing portion 253, and the first elastic element 24 is jacketed on the passing portion 253 to allow the first elastic element 24 to be held between the first body 21 and the second body 22 more steadily.
In addition, the clipping assembly 26 of the embodiment has a first clipping part 261 and a second clipping part 262. The first clipping part 261 and the second clipping part 262 may fasten to each other. In the embodiment, the first clipping part 261 is disposed on the first body 21, and the second clipping part 262 is disposed on the second body 22. The first clipping part 261 is an indentation, and the second clipping part 262 is a hook cooperating with the first clipping part 261. It makes the first body 21 and the second body 22 abut against each other because of the fastening of the first clipping part 261 and the second clipping part 262. The first clipping part 261 may be a hook, and the second clipping part 262 may be an indentation cooperating to the first clipping part 261.
In addition, the first body 21 may be provided with a liquid crystal display panel, a touch panel or an organic light emitting panel. The second body 22 may be provided with a keyboard or an input module.
The portable electronic device 2 of the embodiment may be a portable communication device, an UMPC, a PDA, a notebook, a MP3 player or a handheld game player.
As shown in FIG. 4A to FIG. 4E, to make the features of the embodiment more obviously, the operating process of the portable electronic device 2 of the preferred embodiment of the invention is illustrated with examples.
As shown in FIG. 4A, the portable electronic device 2 is in a closed state. The first clipping part 261 and the second clipping part 262 of the clipping assembly 26 are fastened to each other, and the fastening part 221 and the guiding part 232 are also fastened to each other. Thus, the first body 21 and the second body 22 abut against each other, and both the first elastic element 24 and the second elastic element 233 have the deformation because of the compression.
As shown in FIG. 4B and FIG. 4C, when a user applies an external force F1 to the first body 21 of the portable electronic device 2 to allow the first clipping part 261 to separate from the second clipping part 262, the elastic potential energy of the second elastic element 233 allows the first body 21 to rotate relatively to the second body 22 via the sliding rod 231 and the guiding part 232.
As shown in FIG. 4D, when the protrudent block 212 moves a second end 221b which is not adjacent to the third elastic element 233 in the fastening part 221, and the first end 221a of the fastening part 221 compresses the third elastic element 223, the guiding part 232 is separated from the fastening part 221. When the elastic potential energy of the second elastic element 233 is greater than the force compressing the third elastic element 223, the elastic potential energy of the second elastic element 233 releases. It makes the guiding part 232 separate from the fastening part 221 without an external force. A user also may additionally apply an external force to the first body 21 to assist the guiding part 232 in separating from the fastening part 221.
As shown in FIG. 4E, when the guiding part 232 is separated from the fastening part 221, the elastic potential energy of the compressed first elastic element 24 is released. Thus, the first body 21 rotates relatively to the second body 22 with the pivot 252 as the axis to form an angle θ between the first body 21 and the second body 22. At that moment, a user may operate the electronic device 2 by pressing the keyboard or input assembly of the second body 22.
To sum up, the portable electronic device of the invention has a guiding assembly, a first elastic element and a connecting part to allow the first body and the second body to interact with each other. Via the guiding part fastened to the fastening part, the sliding portion slidingly provided at the track portion and the first elastic element, when the guiding part separates from the fastening part, the first body can not only slide relatively to the second body via the sliding rod, but also can rotate relatively to the second body along the pivot. Compared with the conventional technology, the first body of the invention not only can be operated relatively to the second body in a sliding mode, but also may use the pivot to open relatively to the second body to form an angle. Thus, the first body and the second body are located at different planes, and then the design of the portable electronic device accords with the ergonomics. A portable electronic device which is operated conveniently, does not occupy large room and accords with ergonomics is provided for users.
Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to persons skilled in the art.
