## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This non-provisional application claims priority under 35 U.S.C. §119(a) on Patent Application No(s). 102206527 filed in Taiwan, R.O.C. on Apr. 10, 2013, the entire contents of which are hereby incorporated by reference.
TECHNICAL FIELD
The disclosure relates to a device having opening structure and an opening structure thereof, more particularly to a device having a magnetic opening structure and a magnetic opening structure thereof.
BACKGROUND
For a device having two bodies such as a traditional box, a notebook or a tablet with a keyboard, the elastic element and the hook were usually used to fix the two bodies in a detachable manner in the early days. For example, an elastic hook is used to fix the covering body and the accommodated body of a traditional box. However, the elastic element easily abrades and loses the fastening ability after long-term use. Take the notebook as an example. The hook connected with an elastic element is used to fix the screen and the computer, but the hook may not return to the original position because of elastic fatigue.
Recently, some manufacturers develop a hinge, and the force to release the hinge is various with different opening angles. The internal ramp structure in the hinge is utilized to make the force applied on the opening position different with different opening angles. The notebook with this hinge is designed for the purpose that the force applied to open the screen is larger. Therefore, when the screen is closed, it is more difficult to open it and the screen can be stably fixed to the computer. However, the internal ramp structure is easily damaged when the applied force abrades the ramp. Consequently, it is important to develop a structure which is not only capable of fixing or releasing a device having two bodies but also capable of avoiding the elastic fatigue.

The second body 120 is disposed on the first body 110 and has the closing position and an unlocking position relative to the first body 110. The first body 110 has a first side 111 and a second side 112 opposite to each other. The second body 120 has a first side 121 and a second side 122 opposite to each other. The first side 111 of the first body 110 is pivoted on the first side 121 of the second body 120 around a second axis P2.
The first magnetic component 130 is fixed on the second side 112 of the first body 110. The pivot 160 is disposed on the second side 122 of the second body 120. The second magnetic component 140 and the knob 150 are fixed on the pivot 160 to dispose the second magnetic component 140 and the knob 150 on the second side 122 of the second body 120. The pivot 160 is located at a first axis P1 to pivot the second magnetic component 140 and the knob 150 on the second side 122 of the second body 120 around the first axis P1. The second body 120 has a concave surface 123 with respect to the knob 150. At least part of the knob 150 is exposed to the concave surface 123. In this embodiment, the first axis P1 is parallel to the second axis P2, but the disclosure is not limited thereto. In other embodiment, the first axis P1 is perpendicular to the second axis P2.
The display unit 170 is disposed on the first body 110. The input unit 180 is disposed on the second body 120. In this embodiment, the first body 110 is a cover of a notebook, and the second body 120 is a computer of a notebook. In other embodiments, a first body 110 is a tablet, a computer protection, or a clamping apparatus, and a second body 120 is a keyboard or a touch panel.
FIG. 2A is an enlarged cross-sectional view of the device having an opening structure 10 located at the closing position according to an embodiment of the disclosure. FIG. 2B is an enlarged cross-sectional view of the device having an opening structure 10 located at an unlocking position according to an embodiment of the disclosure. As shown in FIG. 2A and FIG. 2B, the first body 110 has a first locking part 191 disposed on the second side 112 of the first body 110. The second body 120 has a second locking part 192 disposed on the second side 122 of the second body 120. The first body 110 overlaps the second body 120 with the first locking part 191 being adjacent to the second locking part 192 when the second body 120 is located at the closing position. The first locking part 191 separates from the second locking part 192 when the second body 120 is located at the unlocking position.
The first magnetic component 130 has a first pole 131 and is fixed to the first locking part 191. The first pole 131 moves toward the second locking part 192 when locating at the closing position. The second magnetic component 140 has a second pole 141 and a third pole 142. The second pole 141 attracts the first pole 131 and the third pole 142 repels the first pole 131. The second pole 141 and the third pole 142 rotate around the first axis P1 to be located at or leave from the second locking part 192. The second pole 141 or the third pole 142 located at the second locking part 192 moves toward the first locking part 191. The second pole 141 or the third pole 142 leaving from the second locking part 192 moves backward the first locking part 191.
For instance, the first pole 131 of the first magnetic component 130 is S-pole and the first magnetic component 130 further includes a forth pole 132 which is N-pole. The second pole 141 of the second magnetic component 140 is N-pole and the third pole 142 is S-pole. As shown in FIG. 2A, the N-pole second pole 141 in the second locking part 192 attracts the S-pole first pole 131 in the first locking part 191 when the first body 110 and the second body 120 are located at the closing position. The first body 110 overlaps the second body 120 and is fixed on the second body 120.
When opening the first body 110, users rotate the knob 150 exposed to the concave surface 123 on the second body 120 to drive the pivot 160. The pivot 160 drives the second magnetic component 140 to rotate. As shown in FIG. 2B, the N-pole second pole 141 leaves from the second locking part 192 and moves backward the first locking part 191. The S-pole third pole 142 is rotated into the second locking part 192 and moves toward the first locking part 191. The S-pole first pole 131 repels the S-pole third pole 142 to make the first body 110 repelled from the second body 120. At this time, the first body 110 and the second body 120 are located at the unlocking position. Eventually, users lift the first body 110 directly to use the device having the opening structure 10. When users locate the first body 110 and the second body 120 at the closing position, the S-pole first pole 131 attracts the N-pole second pole 141 to the second locking part 192. Users also rotate the knob 150 to make the S-pole first pole 131 attract the N-pole second pole 141 to the second locking part 192, which lets the first locking part 191 and the second locking part 192 be locked magnetically.
In other embodiments, the first pole 131 of the first magnetic component 130 is N-pole, and further includes a forth pole 132 of the first pole 131 which is S-pole. The second pole 141 of the second magnetic component 140 is S-pole, and the third pole 142 thereof is N-pole.
FIG. 3A is an enlarged cross-sectional view of the device having the opening structure 30 located at a closing position according to another embodiment of the disclosure. FIG. 3B is an enlarged cross-sectional view of the device having the opening structure 30 located at an unlocking position according to another embodiment of the disclosure. As shown in FIG. 3A and FIG. 3B, in this embodiment, the device having the opening structure 30 is similar to the device having the opening structure 10. However, a display unit 370 is disposed on the second body 320 in this embodiment. An input unit 380 is disposed on the first body 310. In this embodiment, the second body 320 is a screen of a notebook, and the first body 310 is a computer of a notebook. In other embodiments, the second body 320 is a tablet, and the first body 310 is a keyboard.
For instance, a first pole 331 of a first magnetic component 330 is N-pole and the first magnetic component 330 further includes a fourth pole 332 which is S-pole. A second pole 341 of a second magnetic component 340 is S-pole and a third pole 342 is N-pole. As shown in FIG. 3A, the S-pole second pole 341 I a second locking part 392 attracts the N-pole first pole 331 in a first locking part 391 when a first body 310 and a second body 320 are located at the closing position. The first body 310 overlaps the second body 320 and is fixed on the second body 320.
When opening the first body 310, users rotate a knob 350 exposed to a concave surface 323 on the second body 320 to drive a pivot 360. The pivot 360 drives the second magnetic component 340 to rotate. As shown in FIG. 3B, the S-pole second pole 341 leaves from the second locking part 392 and moves backward the first locking part 391. The N-pole third pole 342 is rotated into the second locking part 392 and moves toward the first locking part 391. The N-pole first pole 331 repels the N-pole third pole 342 to make the first body 310 repelled from the second body 320. At this time, the first body 310 and the second body 320 are located at the unlocking position. Eventually, users lift the first body 310 directly to use the device having the opening structure 30. When users locate the first body 310 and the second body 320 at the closing position, the N-pole first pole 331 attracts the S-pole second pole 341 to the second locking part 392. Users also rotate the knob 350 to make the N-pole first pole 331 attract the S-pole second pole 341 to the second locking part 392, which lets the first locking part 391 and the second locking part 392 be locked magnetically.
In other embodiments, the first pole 331 of the first magnetic component 330 is S-pole, and further includes a forth pole 132 of the first pole 331 which is N-pole. The second pole 341 of the second magnetic component 340 is N-pole, and the third pole 342 of the second magnetic component 340 is S-pole.
To sum up, the device having the opening structure and the opening structure thereof are provided in this disclosure. The opening structure fixes the first body and the second body where the opening structure is disposed by attracting the first pole to the second pole. The opening structure further unlocks the first body from the second body by repelling the first pole from the second pole. The disclosure prevents the instability of the locking state induced by the friction or by elastic fatigue.
