Referring to FIGS. 1 to 3, FIG. 1 is a perspective view illustrating a portable electronic device 50 according to an embodiment of the invention, FIG. 2 is an exploded view illustrating the portable electronic device 50 according to an embodiment of the invention, and FIG. 3 is a bottom view illustrating the inner structure of the portable electronic device 50 according to an embodiment of the invention. The portable electronic device 50 may be a portable computer device with two operation modes of notebook and flat computer. The portable electronic device 50 comprises a host module 52, which may be a computer host module and may be equipped with an input interface (e.g. keyboard, etc.), wherein a slot 521 is formed on the host module 52. The portable electronic device 50 further comprises a display module 54 slidably and rotatably disposed on a side of the host module 52. The display module 54 may be a touch display monitor such that a user can use the display module 54 to perform touch operation.
The portable electronic device 50 further comprises a driving mechanism 56 connected with the host module 52 and the display module 54 and used for driving the display module 54 to slide and rotate relative to the host module 52. Referring to FIGS. 1 to 4, FIG. 4 is an exploded view illustrating the driving mechanism 56 of the invention. The driving mechanism 56 comprises a display module fixing component 58, a host module fixing component 60, a pivoting component 62, at least one protruding structure 64 and a fastening component 66. The display module fixing component 58 is disposed in the display module 54. The host module fixing component 60 is movably disposed in the host module 52. An end of the pivoting component 62 is pivotally connected to the display module fixing component 58 and another end of the pivoting component 62 is fixed to the host module fixing component 60. The pivoting component 62 is capable of driving the host module fixing component 60 to move as being pivoted by the display module fixing component 58. The pivoting component 62 is movably disposed in the slot 521 of the host module 52. The protruding structure 64 is disposed on the host module fixing component 60 and capable of moving relative to an inner side of the host module 52 in line contact manner or point contact manner as the pivoting component 62 drives the host module fixing component 60 to move, so as to guide the host module fixing component 60 to move relative to the host module 52. The driving mechanism 56 may comprise a plurality of protruding structures 64 disposed at the edges of the host module fixing component 60. The position and number of the protruding structures 64 are not limited to this embodiment and can be determined based on practical applications. The fastening component 66 passes through the host module fixing component 60 and is fastened on the pivoting component 62, so as to fasten the host module fixing component 60 to the pivoting component 62. The fastening component 66 may be a screw.
Referring to FIGS. 1 to 5, FIG. 5 is schematic diagram illustrating the operation of the driving mechanism 56 according to an embodiment of the invention. As mentioned in the above, the display module fixing component 58 is disposed in the display module 54, the host module fixing component 60 is movably disposed in the host module 52, an end of the pivoting component 62 is pivotally connected to the display module fixing component 58 and another end of the pivoting component 62 is fixed to the host module fixing component 60. Accordingly, when a user opens the display module 54 shown in FIG. 5 clockwise, the display module fixing component 58 will drive the pivoting component 62 to rotate such that the host module fixing component 60, which is connected to the pivoting component 62, will move within the slot 521 of the host module 52 in a direction indicated by the arrow, so as to drive the display module 54 to move inwardly relative to the host module 52. In other words, when the display module 54 rotates relative to the host module 52, the driving mechanism 56 will drive the display module 54 to move relative to the host module 52. On the other hand, when the user closes the display module 54 shown in FIG. 5 counterclockwise, the display module fixing component 58 will drive the pivoting component 62 to rotate such that the host module fixing component 60, which is connected to the pivoting component 62, will move within the slot 521 of the host module 52 in a reverse direction, so as to drive the display module 54 to move outwardly relative to the host module 52.
In this embodiment, the protruding structure 64 may be a roller or a ball bearing capable of rolling relative to the inner side of the host module 52 in line contact manner. The driving mechanism 56 comprises four protruding structures 64 disposed at opposite sides of the host module fixing component 60, so as to guide the host module fixing component 60 to move relative to the host module 52 stably. The position and number of the protruding structures 64 are not limited to the aforesaid embodiment. For example, referring to FIG. 6, FIG. 6 is a schematic diagram illustrating parts of the driving mechanism 56 according to another embodiment of the invention. In this embodiment, the driving mechanism 56 comprises three protruding structures 64, wherein two shorter protruding structures 64 are disposed at one side of the host module fixing component 60 and one longer protruding structure 64 is disposed at another side of the host module fixing component 60. The three protruding structures 64 can also guide the host module fixing component 60 to move relative to the host module 52 stably. The arrangement of the protruding structures 64 on the host module fixing component 60 can be determined based on practical applications. Since the host module fixing component 60 moves within the host module 52 in line contact manner through rolling of the protruding structures 64 relative to the inner side of the host module 52, the driving mechanism 56 of the invention not only can provide smooth and stable operation but also can avoid abrasion by replacing sliding friction with rolling friction. Especially, if there are four protruding structures 64 disposed at four corners of the host module fixing component 60, the protruding structures 64 will still generate rolling friction even though the host module fixing component 60 does not move straight rather than generating larger friction by a conventional sliding structure. Therefore, the structure of the invention has several advantages of practicability, heavy duty, smooth operation and stability.
Still further, the protruding structure of the invention may be implemented by other structures. For example, referring to FIGS. 7 to 9, FIG. 7 is a perspective view illustrating the host module fixing component 60 and two protruding structures 164 according to another embodiment of the invention, and FIGS. 8 and 9 are perspective view and side view illustrating the host module fixing component 60 and a plurality of protruding structures 264 according to another embodiment of the invention. As shown in FIG. 7, each of the protruding structures 164 is a protruding bar, wherein the protruding bar and the host module fixing component 60 may be formed integrally. The protruding structure 164 is capable of moving relative to the inner side of the host module 52 in line contact manner. In this embodiment, the driving mechanism 56 comprises two protruding structures 164 disposed at opposite sides of the host module fixing component 60, so as to guide the host module fixing component 60 to move relative to the host module 52 stably. The position and number of the protruding structures 164 are not limited to the aforesaid embodiment and can be determined based on practical applications. As mentioned in the aforesaid embodiment, since the protruding structures 164 move relative to the inner side of the host module 52 in line contact manner, the driving mechanism 56 of the invention not only can provide smooth and stable operation but also can reduce resistance and abrasion during movement. Moreover, as shown in FIGS. 8 and 9, each of the protruding structures 264 is a protruding block, wherein the protruding block and the host module fixing component 60 may be formed integrally. The protruding structure 264 is capable of moving relative to the inner side of the host module 52 in point contact manner. In this embodiment, there are four protruding structures 264 disposed at an upper side of the host module fixing component 60 and there are another four protruding structures 264 disposed at a lower side of the host module fixing component 60, so as to guide the host module fixing component 60 to move relative to the host module 52 stably. The position and number of the protruding structures 264 are not limited to the aforesaid embodiment and can be determined based on practical applications. As mentioned in the aforesaid embodiment, since the protruding structures 264 move relative to the inner side of the host module 52 in point contact manner, the driving mechanism 56 of the invention not only can provide smooth and stable operation but also can reduce resistance and abrasion during movement.
Compared with the prior art, the protruding structure of the invention can move relative to the inner side of the host module in line contact manner or point contact manner, so as to guide the display module to slide relative to the host module. The driving mechanism of the invention not only can provide smooth and stable operation but also can avoid abrasion. Furthermore, the driving mechanism of the invention can avoid larger friction generated by the sliding structure of prior art. Accordingly, the structure of the invention has several advantages of practicability, heavy duty, smooth operation and stability.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
