DETAILED DESCRIPTION OF INVENTION
The making and using of the embodiments of the portable electronic devices are discussed in detail below. It should be appreciated, however, that the embodiments provide many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the embodiments, and do not limit the scope of the disclosure.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which this invention belongs. It should be appreciated that each term, which is defined in a commonly used dictionary, should be interpreted as having a meaning conforming to the relative skills and the background or the context of the present disclosure, and should not be interpreted by an idealized or overly formal manner unless defined otherwise.
Referring to FIG. 1, a portable electronic device according to an embodiment of the invention can be a smart watch, primarily comprising a main body 100, a C-shaped member 200, and a hinge module 300. The hinge module 300 has a cylinder structure and pivotally connects the main body 100 with the C-shaped member 200. In this embodiment, the main body 100 can be a display module (LCD display, for example), and a plurality of electronic elements (not shown) are disposed in the C-shaped member 200, such as a processor and an energy storage unit (battery). The electronic elements electrically connect to the main body 100 via the hinge module 300.
Referring to FIGS. 2A and 2B, the C-shaped member 200 comprises an opening 210. When the main body 100 is situated at a first position (FIG. 2A), the main body 100 substantially covers the opening 210, and a display surface D of the main body 100 faces away from the opening 210 for convenient viewing. As shown in FIG. 2B the main body 100 can rotate around an axis A relative to the C-shaped member 200 through the hinge module 300, and move from the first position to a second position (FIG. 2B). When the main body 100 is situated at the second position, the opening 210 is not covered by the main body 100, and the user put the wrist in the C-shaped member 200 through the opening 210. Subsequently, the main body 100 can rotate from the second position around the axis A to the first position to complete the wearing process. It should be noted that an acute angle θ is formed between the axis A and the display surface D (FIG. 2A), wherein the acute angle θ is about 30-80 degrees. Thus, the user can easily rotate the main body 100 to conveniently wear or take off the portable electronic device.
In this embodiment, the main body 100 has the functions of an electronic wallet and a personal digital assistant (PDA). Specifically, when the main body 100 rotates from the first position (FIG. 2A) around the axis A to the second position (FIG. 2B), the processor transfers a disable signal to the main body 100, and the main body 100 turns off the power or executes a logout instruction. Conversely, when the main body 100 rotates from the second position around the axis A to the first position, the processor transfers an enable signal to the main body 100, and the display surface D of the main body 100 shows a login screen. At this time, the user has to provide identification and authentication information (enter an account number and password or identify by a fingerprint, for example) to log in and use the function of electronic wallet or PDA. In another embodiment, the main body 100 comprises an identification unit and a wireless communication module (not shown), wherein the identification unit can be a fingerprint identification module. When the main body 100 rotates from the second position around the axis A to the first position, the processor automatically executes an identification program to identify the authority level of the user by the identification unit. If the authority level of the user identified by the identification unit is not acceptable, the processor can transmit a warning signal via the wireless communication module. If the authority level of the user is accepted by the identification unit, the processor automatically executes a login program. After the processor executes the login program, the wireless communication module is enabled, and the processor can execute the function of electronic wallet or PDA via the wireless communication module. In this embodiment, the user does not need to enter the information through the display surface D to login. Thus, the exposure of personal information when the portable electronic device is lost can be avoided, such that the protection of the personal information can be achieved. Furthermore, when the main body 100 rotates from the second position to the first position, the display surface D immediately shows the login screen, or logs in directly, after the authority level of the user is accepted by the identification unit. Thus, operating time can be reduced for a convenient and quick login.
Referring to FIGS. 3A and 3B, a sliding mechanism is disposed in the hinge module 300, wherein the sliding mechanism comprises a first member 310, a second member 320, and a brush wire 330. The first member 310 is fixed to the main body 100, and the second member 320 is fixed to the C-shaped member 200 and pivotally connected to the main body 100. The first member 310 is rotatable around the axis A relative to the second member 320. In this embodiment, the first and second members 310 and 320 are made of a conductive material (metal or graphite, for example). The second member 320 electrically connects to the electronic elements in the C-shaped member 200 by a wire W (FIG. 3B). As shown in FIG. 3B, an end of the brush wire 330 is fixed to the second member 320, and the first member 310 slidably contacts to the brush wire 330. Thus, the main body 100 and the electronic elements in the C-shaped member 200 can transfer the electronic signals therebetween through the brush wire 330 and the wire W. When the main body 100 rotates from the first position around the axis A to the second position, the first member 310 rotates around the axis A relative to the second member 320. The brush wire 330 continuously connects to the first and second members 310 and 320 during the rotation, such that the main body 100 can be continuously electrically connected to the electronic elements in the C-shaped member 200.
In this embodiment, the second member 320 has a hollow structure, and the first member 310 has a T-shaped cross section and is accommodated in the second member 320. The axis A is located at the central position of the hinge module 300 and passes through the main body 100, the C-shaped member 200, and the hinge module 300 (FIG. 2A). In some embodiments, the brush wire 330 and the second member 320 can also be integrally formed in one piece by molding.
It should be noted that the first and second members 310 and 320 may electrically connect to each other through a plurality of contacts, wherein several electronic elements corresponding to the contacts may be disposed in the C-shaped member 200. Thus, the inner space of the C-shaped member 200 can be occupied effectively, and the thickness of the main body 100 can be reduced.
As shown in FIG. 4, a hinge (nodule 300′ according to another embodiment of the invention comprises a first member 310′ and a second member 320′. The first member 310′ is fixed to the main body 100, and the second member 320′ is fixed to the C-shaped member 200. The first member 310′ is rotatable around the axis A relative to the second member 320′. In this embodiment, the first member 310′ is a plug (jack plug, for example) that comprises a plurality of electrical connection portions P1, P2, and P3. The second member 320′ forms a socket and comprises a plurality of conductive contacts p1, p2, and p3. When the main body 100 is joined to the C-shaped member 200 through the hinge module 300′, the electrical connection portions P1, P2, and P3 respectively contact the conductive contacts p1, p2, and p3, such that the main body 100 and the electronic elements in the C-shaped member 200 electrically connect to each other by the first and second members 310′ and 320′. With the cylinder structure of the first member 310′, the electrical connection portions P1, P2, and P3 of the first member 310′ remain in contact with the conductive contacts p1, p2, and p3 of the second member 320′ during rotation of the main body 100 from the first position around the axis A to the second position.
It should be noted that since the numbers of the signals transferred between the electrical connection portions P1, P2, and P3 and the conductive contacts p1, p2, and p3 is limited, the processor may be disposed in the main body 100, and the electronic element in the C-shaped member 200 may only include a battery. Furthermore, as the first member 310′ is the detachable plug, the main body 100 can be separated from the C-shaped member 200 by pulling out the plug for easy inspection and maintenance. In some embodiments, the second member 320′ can be a plug having a plurality of electrical connection portions, and the first member 310′ may form a socket and have a plurality of conductive contacts corresponding to the electrical connection portions.
If the processor and the energy storage unit are disposed in the main body 100, the main body 100 may not electrically connect to the C-shaped member 200. Referring to FIGS. 5A and 5B, a hinge module 300′′ according to another embodiment comprises a first member 310′′, a second member 320′′, and an elastic element 340′′. The first member 310′′ is fixed to the main body 100, and the second member 320′′ is fixed to the C-shaped member 200. The first member 310′′ is rotatable around the axis A relative to the second member 320′′. The elastic element 340′′ (a spring, for example) connects to the first and second members 310′′ and 320′′. Specifically, a first recess 311′′ and a second recess 312′′ are formed on the outer side of the first member 310′′, and a protrusion 321′′ is formed on the inner side of the second member 320′′. When the main body 100 is situated in the first position, the elastic element 340′′ can provide an elastic force to position the protrusion 321′′ to be accommodated in the first recess 311′′. When the main body 100 rotates from the first position around the axis A to the second position, the protrusion 321′′ can slide from the first recess 311′ to the second recess 312′′, and the elastic element 340′′ can provide an elastic force to position the protrusion 321′′ to be accommodated in the second recess 312′′. Thus, the main body 100 can be alternatively fixed to the first or second position. However, if the protrusion 321′′ is formed on the first member 310′′, and the first and second recesses 311′′ and 312′′ are formed on the second member 320′′, the same functions can also be achieved.
Referring to FIG. 6, a hinge module 300′′′ according to another embodiment comprises a first member 310′′′, a second member 320′′′, an elastic element 340′′′, a first magnetic element M1, and a second magnetic element M2. The first member 310′′′ is fixed to the main body 100, and the second member 320′′′ is fixed to the C-shaped member 200. The first member 310′′′ is rotatable around the axis A relative to the second member 320′′′. The elastic element 340′′′ (a spring, for example) connects to the first and second members 310′′′ and 320′′′. Specifically, the first magnetic element M1 is disposed on the first member 310′′′, and the second magnetic element M2 is disposed on the second member 320′′′. When the main body 100 is situated in the first position, the first magnetic element M1 is adjacent to and oriented toward the second magnetic element M2, such that the main body 100 can be fixed in the first position by the magnetic attraction force between the first and second magnetic elements M1 and M2. In this embodiment, the hinge module 300′′′ further comprises a third magnetic element M3 disposed on the second member 320′′′. The first magnetic element M1 is disposed between the second and third magnetic elements M2 and M3. When the main body 100 rotates from the first position around the axis A to the second position, the first magnetic element M1 is adjacent to and oriented toward the third magnetic element M3, such that the main body 100 can be fixed in the second position by the magnetic attraction three between the first and third magnetic elements M1 and M3.
It should be noted that the aforementioned positioning structure (such as the protrusion 321′′, the first and second recesses 311′′ and 312′′ in FIG. 5A, or the first, second, and third magnetic elements M1, M2, and M3 in FIG. 6) can also be applied to the hinge modules 300 and 300′ shown in FIGS. 3A-4. Moreover, the main body 100 and the C-shaped member 200 in the aforementioned embodiments can be made of a rigid material (plastic or metal, for example), such that the main body 100 can easily rotate between the first and second positions. In some embodiments, a ball bearing or a screw thread can be applied between the first and second members, such that the first member can smoothly rotate relative to the second member.
In summary, a portable electronic device is provided with an acute angle formed between the axis of the hinge module and the display surface of the main body, such that the user can easily operate the portable electronic device. Furthermore, when the main body rotates between the first and second positions, the processor can transmit a disable/enable signal to the main body, such that the protection of personal information can be achieved, and the convenience and safety during usage of the portable electronic device can also be improved.
