DESCRIPTION OF THE PREFERRED EMBODIMENT

For the convenience of understanding, the below embodiment of the I/O port switch structure of the electronic device according to the invention uses the same component numeral as the forward embodiment.

Referring to FIGS. 2A to 2C, a top view and an enlarged perspective view illustrate the embodiment of the I/O port switch structure of the electronic device according to the invention, and a top view of the embodiment of the electronic device of the invention is illustrated. According to FIG. 2A, a motherboard 31 is disposed in the electronic device 3 and an opening 33 is on the side 32 of the electronic device 3. The I/O port switch structure comprises a base 34, several I/O ports 341 and an operation portion 36 (as shown in FIG. 2C). The base 34 is electrically connected to the motherboard 31 through a cable 35, and the I/O ports 341 are installed on the base 34, wherein the electric signals received by the I/O ports 341 are transmitted to the motherboard 31 through the cable 35 for further processing. The operation portion 36 shown in FIG. 2C is connected to the base 34, and the user then operates the base 34 to perform a rotating motion at a predetermined angle, so that one of the I/O ports 341 can be rotated to the position corresponding to the opening 33, and the I/O ports 341 are therefore connected to an external device.

The electronic device 3 can be a notebook computer or a personal digital assistant (PDA), and the operation portion 36 can use a power driving method or a mechanical driving method to enable the base 34 to perform a rotating motion upon demands. The cable 35 comprises a plurality of signal transmission circuits corresponding to the I/O ports 341, and the cable 35 can be carried out by a single cable or a plurality of cables corresponding to the I/O ports 341, and these are all within the scope of the present invention.

Besides, the I/O port switch structure comprises a rotating limiting structure depending upon demands to restrict the rotating angle of the base 34 and preventing the I/O port switch structure from being damaged through improper operations of the user. The rotating limiting structure preferably comprises a first restriction element, a second restriction element and a limiting element. The first and the second restriction elements are installed on the base 34, and the limiting element is installed on the electronic device 3 and can closely approach the first or the second restriction element. Thereby, the base 34 is restricted to perform a rotating motion between the first and the second restriction elements.

Besides, the I/O port switch structure comprises at least a positioning element and a positioning point upon demands. The positioning elements are installed on the base 34, and each position of the positioning element respectively corresponds to these I/O ports 341; and the positioning point is installed on the electronic device 3, and the position of the positioning point corresponds to the opening 33. When the base 34 is performing a rotating motion, the I/O ports 341 can accurately align the position of the opening 33 through the positioning elements and the positioning point.

Furthermore, since the sizes of different I/O ports 341 are different, intervals usually appear as the I/O ports 341 align the position of the opening 33. Therefore, the I/O ports 341 can further comprise a cover body upon demands, so that the cover body can align the opening 33 and approximately seal the opening 33 to keep a better appearance of the electronic device 3 as the I/O ports 341 are rotated to the position corresponding to the opening 33.

Please note that three I/O ports 341 are installed on the base 34 in the aforementioned embodiment, and this is only for example but not the limiting to the invention, two or four, or much more I/O ports 341 can be installed on the base 34 and these are all within the scope of the present invention.

Referring to FIGS. 3A to 3D, a top view of the I/O port switch structure, a schematic view of the clockwise rotation of the base, a schematic view of the counter-clockwise rotation of the base and a sectional view of the hatch line A-A′ according to FIG. 3A of the other embodiment are illustrated. According to FIG. 3A, three I/O ports 341 are installed on the base 34, wherein the base 34 is pivotally connected to the electronic device 3 through a spindle 41, and the base 34 can be rotated through the spindle 41. A first restriction element 42 and a second restriction element 43 are disposed on the surface of the base 34 closely approached to the electronic device 3, and a position limiting element 44 is installed on the electronic device 3. These elements are used to restrict the rotating angle of the base 34. The electronic device 3 comprises a positioning point 45 (as shown in FIG. 3D) and the base 34 comprises a plurality of positioning elements 46, wherein each positioning element 46 respectively corresponds to an I/O port 341, and the positioning point 45 can be inserted with the positioning elements 46 as shown in FIG. 3D. The positioning point 45 can be installed on the position limiting element 44 upon demands.

Referring to FIG. 3B, as a user rotates the base 34 in the clockwise direction r1 through the operation portion, the first restriction element 42 will closely approach the position limiting element 44, so that the base 34 can not be continuously rotated in the clockwise direction r1 to prevent the cable 35 from being snapped due to the excessive rotation of the base 34. The positioning point 45 is also inserted into one of the positioning elements 46, so that the one of the I/O ports 341 aligns the opening 33 much more accurately.

Referring to FIG. 3C, as a user rotates the base 34 in the counter-clockwise direction r2 through the operation portion, the second restriction element 43 will closely approach the limiting element 44, so that the base 34 can not be continuously rotated in the counter-clockwise direction r2. The positioning point 45 is also inserted into the other one of the positioning elements 46, so that the other one of the I/O ports 341 aligns the opening 33. By way of the operating relationship among the first limiting element 42, the second limiting element 43 and the position limiting element 44, the rotating angle of the base 34 can be restricted to prevent the cable 35 from being snapped due to the excessive rotation of the base 34. Since the positioning point 45 is respectively inserted into different positioning elements 46, the I/O ports 341 can be further accurately rotated to the opening 33 when the base rotates. The positioning element 46 and the positioning point 45 shown in FIG. 3D are only for example but not limiting to the present invention. Any structure, which can achieve the positioning effect, is all within the scope of the subject invention.

Comparing with FIGS. 2A and 2B, the I/O ports 341 shown in FIGS. 3A to 3C comprise a cover plate 49. The opening can be approximately sealed by the cover plate 49 to keep a better appearance of the electronic device 3 when one, of the I/O ports 341 aligns the opening 33.

The above examples are intended for illustrating the embodiments of the present invention, but not for restricting the scope of protection of the present invention. Any modification or equivalent arrangements which belong to the spirit and category of the invention should be within the scope based on the claims as appended.
