DETAILED DESCRIPTION OF THE EMBODIMENTS
Please refer to FIG. 2 which is a bottom view showing an electronic device according to a preferred embodiment of the invention. The electronic device 200 according to this embodiment may be any information appliance such as a notebook, a smart phone, a personal digital assistant (PDA) and so on. This embodiment only takes the notebook for example.
The electronic device 200 includes a first casing 300, a second casing 400, and a flip apparatus 500. The flip apparatus 500 includes a sliding mechanism 600, a rotating mechanism 700, and an actuating element 800. The sliding mechanism 600 is disposed at the first casing 300 and is slidably connected to the second casing 400 to drive the first casing 300 to slide to a rotating position relative to the second casing 400.
Please refer to FIG. 3 which is an exploded view showing the electronic device in FIG. 2. The rotating mechanism 700 is pivotally connected to the second casing 400. The rotating mechanism 700 includes a rotating block 710, a moving block 720, and an elastic element 730. The rotating block 710 is pivotally connected to the second casing 400 and is fixed to the first casing 300. The moving block 720 is slidably provided at the rotating block 710 and is fixed to the sliding mechanism 600 (as shown in FIG. 2). The elastic element 730 is pivotally connected to the rotating block 710. The elastic element 730 has elastic potential energy and the rotating block 710 can be driven to rotate by releasing the elastic potential energy.
As shown in FIG. 2 and FIG. 3, the actuating element 800 is disposed at the second casing 400 and is used for restricting the rotating mechanism 700. When the first casing 300 slides to the rotating position relative to the second casing 400, the actuating element 800 can release the rotating mechanism 700 to release the elastic potential energy of the elastic element 730. Thus the rotating block 710 is driven to rotate and the moving block 720 is driven to slide relative to the rotating block 710, and then the first casing 300 is driven to rotate relative to the second casing 400.
Please refer to FIG. 4A to FIG. 4C. FIG. 4A is a schematic diagram showing a state of the electronic device in FIG. 2 before the first casing slides relative to the second casing; FIG. 4B is a schematic diagram showing a state of the electronic device in FIG. 2 during the first casing slides relative to the second casing to a rotating position; FIG. 4C is a schematic diagram showing a state of the electronic device in FIG. 2 after the first casing rotates relative to the second casing. In FIG. 4A, the first casing 300 and the second casing 400 superpose. Thus the electronic device 200 can be easily carried or stored.
In FIG. 4B, the first casing 300 is in the rotating position. The first casing 300 slides from the position shown in FIG. 4A to the rotating position by the sliding mechanism 600 (as shown in FIG. 2). The actuating element 800 is used for restricting the rotating mechanism 700 (as shown in FIG. 2) to allow the first casing 300 to be positioned in the rotating position. Further, in this embodiment, a displaying element 220 is provided at the first casing 300, and a keyboard 230 is provided at the second casing 400. Thus when the first casing 300 is in the rotating position, a user can watch the displaying element 220 with others and use the keyboard 230 at the same time.
In FIG. 4C, there is an included angle between the first casing 300 and the second casing 400 to allow a user to watch the displaying element 220 from another angle and to use the keyboard 230 easily.
The electronic device 200 is further described hereinbelow. Please refer to FIG. 5 which is a bottom view showing the first casing in FIG. 2. The first casing 300 has two stoppers 330. When the first casing 300 slides relative to the second casing 400 (as shown in FIG. 2), the stoppers 330 are used for limiting the sliding track of the first casing 300 relative to the second casing 400 to allow the first casing 300 to be positioned in the rotating position as shown in FIG. 4B.
Further, please refer to FIG. 6A which is a schematic diagram showing part of the electronic device in FIG. 2. FIG. 6A shows part of the element just to facilitate the description of the connecting and motion relationship between the elements, while it is not used for limiting the invention. The second casing 400 in FIG. 6A has a containing recess 410, and the rotating block 710 and the moving block 720 are contained in the containing recess 410. In this embodiment, the rotating block 710 has a slot 711. The actuating element 800 is provided within the range R1 and cooperates with the slot 711 to restrict the rotating mechanism 700.
Please refer to FIG. 6B which is a schematic diagram showing a state of the electronic device in FIG. 6A during the actuating element and the slot of the rotating block cooperate with each other. The actuating element 800 includes a latch 811, a spring 840, and a button 813. The latch 811 is pivotally connected to the second casing 400 (as shown in FIG. 6A). The latch 811 can be locked in the slot 711 to limit the rotating mechanism 700, and therefore the first casing 300 (as shown in FIG. 2) is correspondingly restricted and is positioned in the rotating position (as shown in FIG. 4B).
One end of the spring 840 of the actuating element 800 is sleevedly connected to the latch 811, and the other end of the spring 840 is coupled to the second casing 400. The button 813 is coupled to one end of the latch 811. When the button 813 presses the latch 811 in a direction D1, the latch 811 rotates around a pivoting point 814. At this moment, the other end of the latch 811 moves in a direction D2 to release the rotating mechanism 700. After the latch 811 releases the rotating mechanism 700, the elastic potential energy of the spring 840 drives the latch 811 to be restored to an initial position.
Please refer to FIG. 7 which is another schematic diagram showing part of the electronic device in FIG. 2. In this embodiment, the elastic element 730 may be, for example, a torsion spring. After the actuating element 800 (as shown in FIG. 6B) releases the rotating mechanism 700, the elastic element 730 also releases the elastic potential energy to drive the rotating block 710 to rotate. In this embodiment, the flip apparatus 500 (as shown in FIG. 2) further includes a rotating shaft 900 disposed at the rotating block 710. The rotating block 710 is pivotally connected to the second casing 400 via the rotating shaft 900 and rotates around the rotating shaft 900.
The elastic potential energy of the elastic element 730 not only can drive the rotating block 710 to rotate but also can drive the moving block 720 to slide relative to the rotating block 710. In this embodiment, the rotating block 710 has at least one blocking element 712, and the moving block 720 has at least one protruding element 722. The position of the blocking element 712 corresponds to that of the protruding element 722 thereby to limit the sliding track of the moving block 720 relative to the rotating block 710. The second casing 400 according to this embodiment has at least one sloping guiding groove 423, and the protruding element 722 has at least one protruding post 723. The protruding post 723 is inserted into the sloping guiding groove 423. When the moving block 720 and the first casing 300 slide relative to the rotating block 710, the protruding post 723 moves along the sloping guiding groove 423.
The first casing 300 according to this embodiment has a smooth corner 320 adjacent to the second casing 400. Thus, when the first casing 300 rotates relative to the second casing 400, the first casing 300 contacts the second casing 400 via the smooth corner 320 to avoid affecting the rotation of the first casing 300. Further, the rotating block 710 has at least one raised element 713, and the containing recess 410 has a side wall 411. When the raised element 713 is against the side wall 411, the raised element 713 is used for limiting the rotating angle of the first casing 300 relative to the second casing 400.
In the flip apparatus and the electronic device using the same according to the above embodiments of the invention, the sliding mechanism and the rotating mechanism are respectively used to drive the first casing to slide and rotate relative to the second casing. When the first casing slides to the rotating position by the sliding mechanism, the actuating element is used for restricting the rotating mechanism. When the actuating element releases the rotating mechanism, the rotating mechanism drives the first casing to rotate relative to the second casing to form an angle between the first casing and the second casing. Thus the position of the first casing can be determined as required, and the position of the first casing relative to the second casing can be altered by the sliding mechanism and the rotating mechanism.
Although the present invention has been described in considerable detail with reference to certain preferred embodiments thereof, the disclosure is not for limiting the scope of the invention. Persons having ordinary skill in the art may make various modifications and changes without departing from the scope and spirit of the invention. Therefore, the scope of the appended claims should not be limited to the description of the preferred embodiments described above.
