Please refer to FIG. 1. FIG. 1 is a block diagram of a portable electronic apparatus 50 according to a first embodiment of the present invention. The portable electronic apparatus 50 can be a clamshell mobile phone, a notebook computer, an electronic apparatus with two modules and so on. The portable electronic apparatus 50 includes a first module 52, a second module 58, and a first hinge assembly 64. The first module 52 can be a host module, and the second module 58 can be a display module. The first module 52 includes a first housing 54 and a host 56. The first housing 54 is for covering inner components inside the first module 52. The host 56 is installed inside the first housing 54 and is for controlling operation of the portable electronic apparatus 50. The second module 58 includes a second housing 60, and a screen 62 installed inside the second housing 60 and electrically connected to the host 56 for displaying image signals transmitted from the host 56. The first hinge assembly 64 is connected to the first module 52 and the second module 58 so that the second module 58 is capable of rotating relative to the first module 52 to be in an opening condition or in a close condition.
Please refer to FIG. 2 to FIG. 5. FIG. 2 is a schematic drawing of the portable electronic apparatus 50 in the close condition according to the first embodiment of the present invention. FIG. 3 is a schematic drawing of the portable electronic apparatus 50 in the half-open condition according to the first embodiment of the present invention. FIG. 4 is a schematic drawing of the portable electronic apparatus 50 in the open condition according to the first embodiment of the present invention. FIG. 5 is a lateral view of folding the portable electronic apparatus 50 according to the first embodiment of the present invention.
Go into detail, the first housing 54 of the first module 52 has a first containing space 66. The first hinge assembly 64 includes a first hinge 68, a second hinge 70, and a first swing member 72. The first hinge 68 is installed inside the first containing space 66 and pivotally connected to the first housing 54. The second hinge 70 is pivotally connected to the second housing 60. The first swing member 72 is connected to the first hinge 68 and the second hinge 70.
As shown in FIG. 2 and FIG. 5, the first assembly 64 is contained inside the first containing space 66 completely when the portable electronic apparatus 50 is in the close condition, that is, the second module 58 and the first module 52 are folded up. At this time, the first hinge assembly 64 can not bee seen from the outline of the portable electronic apparatus 50. The first module 52 and the second module 58 cover the first hinge assembly 64 together. In other words, the first hinge assembly 64 is hidden inside the portable electronic apparatus 50. As shown in FIG. 3 and FIG. 5, when the second module 58 opens with respect to the first module 52, the second module 58 rotates in a clockwise direction relative to the first module 52 and pivots on a first end 601 of the second housing 60 as a fulcrum. The second module 58 drives the first swing member 72 connected to the first hinge 68 to rotate in a counterclockwise direction relative to the first module 52. In this embodiment, the first end 601 of the second housing 60 can be formed as fillet structure so that the second module 58 is capable of rotating relative to the first module 52 smoothly when contacting with the first housing 54 of the first module 52 for preventing interference of fold. When the second module 58 rotates relative to the first module 52, the second hinge 70 and the first swing member 72 are exposed outside the first containing space 66 partly. When the angle between the second module 58 and the first module 52 increases, the exposed part of the second hinge 70 and the first swing member 72 increases. As shown in FIG. 4 and FIG. 5, when the second module 58 opens completely with respect to the first module 52, the second module 58 can rotate to a position parallel to the first module 52 closely without interference with the first module 52 due to the disposition of the second hinge 70. Thus, the mechanism can enlarge a view angle of the second module 58 of the portable electronic apparatus 50. Additionally, the first hinge 68 of the first hinge assembly 64 can be installed inside the second housing 60 and pivotally connected to the second module 58, and the second hinge 70 can be pivotally connected to the first housing 54. The operation is the same as the above-mentioned embodiment. In a word, the first module 52 is a host module, and the second module 58 is a display module in this embodiment. However, the first module 52 also can be a display module, and the second module 58 can be a display module accordingly in another embodiment.
Please refer to FIG. 6. FIG. 6 is a schematic drawing of a portable electronic apparatus 100 according to a second embodiment of the present invention. The different between the portable electronic apparatus 100 in the second embodiment and the portable electronic apparatus 50 in the first embodiment is that the portable electronic apparatus 100 further includes a second hinge assembly 104 connected to the first module 52 and the second module 58. The second hinge assembly 104 includes a third hinge 106, a fourth hinge 108, and a second swing member 110. The third hinge 106 is installed inside the first housing 54 and pivotally connected to the first housing 54. The fourth hinge 108 is pivotally connected to the second housing 60. The second swing member 110 is connected to the third hinge 106 and the fourth hinge 108. The first housing 54 further has a second containing space 102. The operation of the portable electronic apparatus 100 is similar with the one of the portable electronic apparatus 50. The first hinge assembly 64 and the second hinge assembly 104 are completely contained inside the first containing space 66 and the second containing space 102 respectively when the first module 52 and the second module 58 are close substantially.
The second hinge 70, the fourth hinge 108, the first swing member 72, and the second swing member 110 are exposed outside the first containing space 66 and the second containing space 102 partly when the second module 58 opens with respect to the first module 52. The rest of the features are essentially the same, thus a further description is hereby omitted. Additionally, the third hinge 106 of the second hinge assembly 104 can be installed inside the second housing 60 and pivotally connected to the second module 58, and the fourth hinge 108 can be pivotally connected to the first housing 54. The operation is the same as the above-mentioned embodiment. The number of the hinge assembly is not limited to the above-mentioned embodiment and depends on demands of design and structural intensity.
In contrast to the conventional portable electronic apparatus, the portable electronic apparatus of the present invention utilizes the invisible dual-axis hinge mechanism for an opening mechanism of the display module with respect to the host module. It can enlarge the view angle of the portable electronic apparatus. The portable electronic apparatus with the invisible hinge mechanism has following disadvantages: uniformity of aesthetic outline, preventing fracture of the hinge when dropping the clamshell mobile phone, small fabricating tolerance causing increase of fabricating precision, and small size of the portable electronic apparatus.
