DETAILED DESCRIPTION OF THE INVENTION
The invention is exemplified by the embodiments disclosed below. However, these embodiments are for exemplification only, not for limiting the scope of protection of the invention. Also, secondary elements are omitted in these embodiments so as to highlight the technical features of the invention.
Referring to FIG. 1, a portable computer 100 of a preferred embodiment of the invention is shown. The portable computer 100 includes a display monitor 110, a host and a hinge mechanism 130 (the host being blocked by the display monitor 110 is not illustrated in FIG. 1). As indicated in FIG. 1, the hinge mechanism 130 is a trapezoidal structure. The hinge mechanism 130 is connected with the display monitor 110 and the host. The hinge mechanism 130 is for rotating the display monitor 110 and the host along an axial line L relatively.
Referring to FIGS. 2 ̃3. FIG. 2 shows a 3-D diagram of a hinge mechanism 130, FIG. 3 shows a top view of the hinge mechanism 130. As indicated in FIG. 2, the hinge mechanism 130 includes a bottom board 131, a pivot 132, a power adapter 133, a slanting board 134, a parallel board 135, a sliding-rail structure 136 and a locking bracket 137. The pivot 132 is disposed on the bottom board 131. The first end 132a of the pivot 132 is connected with the host, and the second end 132b of the pivot 132 is connected with the display monitor 110. The first end 132a of the pivot 132 is fixed on the bottom board 131. The bottom board 131 has a locking hole 131a used for screwing the host and the bottom board 131. The second end 132b of the pivot 132 is screwed on the display monitor 110.
When the first end 1 32a of the pivot 132 rotates with respect to the second end 132b, the host and the bottom board 131 are moved together with the first end 132a, and the display monitor 110 is moved together with the second end 132b of the pivot 132. Thus, the display monitor 110 and the host can be rotated relatively.
The parallel board 135 is disposed on the bottom board 131 and is substantially parallel to the pivot 132. The slanting board 134, which slants to the pivot 132, is disposed on the bottom board 131 and connected with the pivot 132 and the parallel board 135. In the present embodiment of the invention, the contained angle between the slanting board 134 and the pivot 132 is substantially 45 degrees. Thus, the parallel board 135, the slanting board 134 and the pivot 132 substantially form a trapezoidal structure. In the present embodiment of the invention, the parallel board 135 and the bottom board 131 are integrally formed in one piece, but the slanting board 134 and the bottom board 131 are separated from each other.
Moreover, the sliding-rail structure 136 is erected on the bottom board 131 for disposing the power adapter 133. During the assembly process, the two protrusions 133a of the power adapter 133 vertically slides into the sliding-rail structure 136, so that the power adapter 133 is firmly disposed on the bottom board 131. However, only one protrusion 133a is illustrated in FIG. 2 due to the restriction of view angle.
The two sliding-rail structures 136 do not necessarily disposed on opposite positions. For example, one sliding-rail structure 136 is closer to the slanting board 134, and the other sliding-rail structure 136 is farther from the slanting board 134. It is assured that the power adapter 133 can correctly slide into the sliding-rail structure 136 as long as the two protrusions 133a of the power adapter 133 correspond to the two sliding-rail structures 136.
Next, the slanting board 134 is assembled on the bottom board 131. Meanwhile, the first opening 134a (illustrated in FIG. 2) of the slanting board 134 exposes the power adapter 133, so that the user can insert the power connecter 200 from the outside of the hinge mechanism 130.
Referring to both FIG. 2 and FIG. 4. FIG. 4 s shows a 3-D diagram of a locking bracket 137 viewed from another view angle. The locking bracket 137 includes a main board 1370, a first extending board 1371, a second extending board 1372 and a third extending board 1373. The locking bracket 137 is disposed on the bottom board 131. The main board 1370 has a locking hole 137a. The parallel board 135 has a second opening 135a. 
When the locking bracket 137 is disposed on the bottom board 131, the main board 1370 and the parallel board 135 are closed together, and the second opening 135a exposes the locking hole 137a of the locking bracket 137. The user can insert the T-shaped locker 410 of the locking chain 400 into the second opening 135a and the locking hole 137a, and rotate the T-shaped locker 410 by 90 degrees, such that the T-shaped locker 410 will not be detached from the locking hole 137a and the second opening 135a. Then, the user can further fix the other end of the locking chain 400 at an unmovable object. Thus, the burglar cannot move the portable computer 100 away.
As indicated in FIG. 2, the first extending board 1371 and the second extending board 1372 are respectively extended from the first lateral side 1370a and the second lateral side 1370b of the main board 1370, both the contained angle between the main board 1370 and the first extending board 1371 and the contained angle between the main board 1370 the second extending board 1372 are substantially 90 degrees. Thus, the 90-degree bending design of the first extending board 1371 and the second extending board 1372 protects the locking bracket 137 from being deformed in the positive and the negative direction of the X-axis.
Likewise, as indicated in FIG. 4, the third extending board 1373 is extended from the third lateral side 1370c of the main board 1370, and the contained angle between the main board 1370 and the third extending board 1373 is substantially 90 degrees. Thus, the 90-degree bending design of the third extending board 1373 prevents the locking bracket 137 from being deformed in the positive and the negative direction of the Z-axis.
The main board 1370, the first extending board 1371, the second extending board 1372 and the third extending board 1373 are integrally formed in one piece. For example, these extending boards are formed by way of metallic casting, further enhancing the structural strength of the locking bracket 137.
During the process of assembly, the first extending board 1371 is directly screwed on the bottom board 131, and the two extending boards 1372 and the third extending board 1373 are also screwed on the host.
Referring to FIG. 5, a portable computer 100, a desktop 300 and a power connecter 200 are shown. As the slanting board 134 tilts 45 degrees with respect to the pivot 132 (the slanting board 134 and the pivot 132 are illustrated in FIG. 2), when the portable computer 100 is placed on a rectangular desktop 300, a space S is formed between the slanting board 134 and the corner of the desktop 300. The space S exactly receives the power connecter 200, so that the user can push a lateral side 100a of the portable computer 100 to a lateral side 300a of the desktop 300 and the utilization of space is maximized.
The portable computer and the hinge mechanism thereof disclosed in the above embodiments of the invention have many advantages exemplified as below.
1. When the first end of the pivot rotates with respect to the second end, the host and the bottom board will move together with the first end, and the display monitor will move together with the second end of the pivot. Thus, the display monitor can rotate around the host.
2. The sliding-rail structure is erected on the bottom board for disposing the power adapter. During the process of assembly, the two protrusion of the power adapter vertically slide into the sliding-rail structure, so that the power adapter is firmly disposed on the bottom board.
3. The first extending board, the second extending board, and the third extending board are respectively extended from the first lateral side, the second lateral side and the third lateral side of the main board. The contained angles between the main board and the first extending board, the second extending board and the third extending board are all substantially 90 degrees. Thus, the 90-degree bending design of the first extending board, the second extending board and the third extending board prevents the locking bracket from being deformed in the positive and the negative direction of the X-axis and the Z-axis.
4. The main board, the first extending board, the second extending board and the third extending board are integrally formed in one piece, further enhancing the structural strength of the locking bracket.
5. As the slanting board tilts 45 degrees with respect to the pivot, when the portable computer is placed on a rectangular desktop a space is formed between the slanting board and the corner of the desktop. The space exactly receives the power connecter, so that the user can push a lateral side of the portable computer to a lateral side of a rectangular desktop and the utilization of space is maximized.
