Referring to FIG. 2, in assembly of the supporting device 100, the power plate 31 is mounted in the first mounting hole 131. The first conducting portion 333 of the first conducting member 33 is aligned with the first mounting hole 131. The first conducting portion 333 is pressed to be received in the first mounting hole 131. The second insulating portion 353 of the insulating member 35 is aligned with the second mounting hole 335. The insulating member 35 is pressed to make the second insulating portion 353 to be received in the first conducting member 33. The second conducting portion 373 of the second conducting member 37 is aligned with the third mounting hole 355. The head portion 371 of the second conducting member 37 is pressed and the second conducting portion 373 passes through the third mounting hole 355 and the second mounting hole 335, thereby the second conducting member 37 is assembled to the insulating member 35.
The rotating portion 53 of the rotating structure 50 is aligned with the head portion 371 of the second conducting member 37. The rotating structure 50 is mounted on the fixing structure 30 with the rotating portion 53 latching with the main portion 331 of the first conducting member 33. Then, the rotating portion 53 is electrically connected to the main portion 331 and can rotate relative to the main portion 331. The assembling portion 713 of the first supporting member 71 is aligned with the mounting portion 55. The first supporting member 71 is mounted to the rotating structure 50 and the first absorbing portion 715 is electrically connected to the conducting sheet 553. The protruding portion 733 of the second supporting member 73 is aligned with the guiding hole 717 and the receiving hole 57. The protruding portion 733 passes through the guiding hole 717 and is received in the receiving hole 57. In this way, the first absorbing portion 715 is coplanar with the second absorbing portion 735.
Referring to FIG. 3, the power plate 31 includes a first conducting point 311 and at least one second conducting point 373. The first conducting point 311 is spaced apart from the second conducting point 373. In this embodiment, there are one first conducting point 311 and two second conducting points 313. The two conducting points 313 are positioned surround the first conducting point 311. The first conducting point 311 is a positive conducting point. The second conducting points 313 are negative conducting points. In other embodiments, the two second conducting points 313 can be replaced by a conducting ring.
As illustrated, a positioning hole 7331 is defined at an axis direction of the protruding portion 733. The second supporting member 73 further includes an elastic portion 737 and a second conducting sheet 739. The elastic portion 737 is received in the positioning hole 7331 with one end of the elastic portion 737 fixed to the second absorbing portion 735 and the other end of the elastic portion 737 electrically connected to the conducting sheet 739.
When the first conducting portion 333 is received in the first mounting hole 131 of the receiving portion 13, a peripheral edge of the first conducting portion 333 resists and electrically connected to the second conducting point 313. Due to the first absorbing portion 715 is electrically connected to the conducting sheet 553 and the rotating portion 53 is electrically connected to the main portion 331, thus the first absorbing portion 715, the conducting sheet 553, the rotating portion 53, the main portion 331, and the first conducting portion 333 are connected in order, thereby forming a first charging path.
When the second conducting portion 373 passes through the third mounting hole 355 and the second mounting hole 335, the second conducting portion 373 contacts with and is electrically connected to the first conducting point 311 on the power plate 31. Due to the second absorbing portion 735 is electrically connected to the conducting sheet 739 through the elastic member 737 and the conducting sheet 739 resists the head portion 371 of the second conducting member 37, thus the second absorbing portion 735, the elastic member 737, the conducting sheet 739, the head portion 371, the second conducting portion 373, and the first conducting point 311 are electrically connected in order, thereby forming a second charging path. In this embodiment, the first charging path is a negative charging path and the second charging path is a positive charging path.
Referring to FIG. 4, when the supporting device 100 is used, the portable electronic device 200 is placed on a supporting surface formed by the first absorbing portion 715 and the second absorbing portion 735. Then, the portable electronic device 200 can be steadily supported by the first absorbing portion 715 and the second absorbing portion 735. When the rotating portion 53 rotates relative to the fixing structure 30, the portable electronic device 200 rotates along with the rotating portion 53.
In addition, referring to FIG. 5, the portable electronic device 200 can include a housing 201. In this embodiment, the housing 201 is configured to coordinate with the supporting device 100 to charge the portable electronic device 200. In detail, the housing 201 includes a first conducting member 203 and a second conducting member 205. In this embodiment, the first conducting member 203 is a positive conducting point corresponding to the first conducting point 311. The second conducting member 205 is a negative conducting point corresponding to the second conducting points 313. The first conducting member 203 and the second conducting member 205 are both electrically connected to an inner charging circuit of the portable electronic device 200. Therefore, when the portable electronic device 200 with the housing 201 is supported by the supporting device 100. Due to the supporting device 100 forming two charging paths as described above. Then, if the power plate 31 of the fixing structure 30 is electronically connected to the power supply 300, the second absorbing portion 735 is electrically connected to the first conducting member 203 and the first absorbing portion 715 is electrically connected to the second conducting member 205. The power supply 300 charges the portable electronic device 200 on the supporting device 100 through the above positive charging path and the negative charging path.
In other embodiments, the first conducting point 311 of the supporting device 100 can also be a negative conducting point and the second conducting point 313 is a positive conducting point. Then, the first absorbing portion 715, the conducting sheet 553, the rotating portion 53, the main portion 331, the first conducting portion 333, and the second conducting point 373 are connected in order, thereby forming a positive charging path. The second absorbing portion 735, the elastic member 737, the conducting sheet 739, the head portion 371, the second conducting portion 373, and the first conducting point 311 are electrically connected in order, thereby forming a negative charging path.
The embodiments shown and described above are only examples. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, especially in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
