1. Technical Field
The present disclosure relates to portable electronic devices and, particularly, to a portable electronic device with a special prompt of incoming calls or short messages.
2. Description of Related Art
With the development of technology, portable electronic devices have become widely used. To alert users of incoming calls or short message, portable electronic devices are equipped with prompts, e.g. audios, vibration, and flashing lights.
However, audios may disturb others under certain conditions such as in a meeting. Vibration may cause unintentional damages to the portable electronic devices such as falling off a desk. A dim flashing light may not be easily sensed by a user.
Therefore, there is room for improvement within the art.
Many aspects of a portable electronic device can be better understood with reference to the following drawings. These drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present portable electronic device. Moreover, in the drawings like reference numerals designate corresponding sections throughout the several views.
The cover assembly 101 includes a first cover 11 and a second cover 12 combined with the first cover 11. The first cover 11 includes a mounting portion 111 defined thereon. In this embodiment, the mounting portion 111 is a shoulder hole includes a first bottom wall 1111 and a through hole 1113 through the first cover 11.
The rotating mechanism 103 is sandwiched between the first cover 11 and the second cover 13. The rotating mechanism 103 includes a rotating assembly 20 and a driving assembly 30.
Referring to
The driven wheel 23 includes a base 231, a support portion 232, and a connecting portion 233. The support portion 232 and the connecting portion 233 protrude from opposite surfaces of the base 231, respectively. The support portion 232 is a generally annular resisting wall with a support wall 2321. The support wall 2321 defines a plurality of grooves 2322 to enlarge the friction force when the support portion 232 is located on a surface, e.g., a desk. The support portion 232 protrudes from a peripheral edge of the base 231, and exposing out of the mounting portion 111. The connecting portion 233 is a hollow column, and includes a peripheral wall 2331 and three resisting arms 2332. The resisting arms 2332 protrude from and extend along the peripheral wall 2331, corresponding to the stopping blocks 217. One end of each resisting arm 2332 is fastened to the peripheral wall 2331. The other end of the resisting arm 2332 is a free end with a resisting surface 2333 and a slope surface 2334. Each resisting surface 2333 abuts against the stopping surface 2173 of a corresponding stopping block 217. Each sliding surface 2171 faces a corresponding slope surface 2334. The base 231 includes a hollow pivoting column 237 protruding therefrom at a center. The pivoting column 237 is received in the connecting portion 233. The pivoting column 237 receives the pivoting pole 215 therein, so that the driving wheel 21 and the driven wheel 23 rotate about a same axis, i.e., the pivoting column 237.
The driving assembly 30 includes a pivoting shaft 301 and a power generating device 302. The pivoting shaft 301 includes a worm gear 31 axially disposed at one end thereof. The pivoting shaft 301 is connected to the power generating device 302 at the other end, thus the power generating device 302 drives the pivoting shaft 301 to rotate clockwise or counter clockwise. If the pivoting shaft 301 rotates clockwise, each resisting surface 2333 resists one corresponding stopping surface 2173 and drives the driven wheel 23 rotate. If the pivoting shaft 301 rotates counter clockwise, each sliding surface 2171 of the driving wheel 21 slides along one corresponding slope surface 2334, thus the driven wheel 23 stays put. The power generating device 302 is an electric motor in the exemplary embodiment.
Referring to
In use, the power generating device 302 is triggered to rotate the pivoting shaft 301 clockwise. The worm gear 31 rotates clockwise with the pivoting shaft 301. Meanwhile, the worm gear 31 drives the gear portion 212 to rotate the driven wheel 23. Thus, when the support wall 2321 is securely placed on a surface, e.g., desk, the portable electronic device 100 can be rotated about the pivoting pole 215. Thus, the portable electronic device 100 can efficiently remind a user of incoming calls or short message by rotating itself without noise.
In an alternative embodiment, the portable electronic device 100 can be provided with typical prompts, e.g. audios, vibration, and flashing lights besides the present rotating prompt. Thus, the portable electronic device 100 further includes a control module (not shown), used to facilitate a user selecting a preferred prompt. If the portable electronic device 100 isn't set in the present rotating prompt, the power generating device 302 will be triggered to rotate the pivoting shaft 301 counter clockwise, thus, the sliding surface 2171 slides along the slope surface 2334, thus the driven wheel 23 stays put.
In a third alternative embodiment, the driven wheel 23 can includes a plurality of flashes (not shown) disposed thereon, when the driven wheel 23 rotates, the flashes are triggered together to alert a user.
In a fourth alternative embodiment, the number of stopping blocks 217 is not limit to three, but can be one, two or other numbers, the number of connecting portion 233 alters as that of the stopping blocks 217.
In a fifth alternative embodiment, the stopping blocks 217 can be disposed on the driven wheel 23, correspondingly, the connecting portion 233 can be disposed on the driving wheel 21.
It is to be understood, however, that even through numerous characteristics and advantages of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of the disclosure, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of sections within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms, in which the appended claims are expressed.
