Specific embodiment

For further illustrating each embodiment, the present invention is provided with accompanying drawing.These accompanying drawings are the invention discloses one of content Point, it is mainly in order to illustrate embodiment, and can coordinate the associated description of the description operation principles to explain embodiment.Cooperation ginseng Examine these contents, those of ordinary skill in the art will be understood that other possible embodiments and advantages of the present invention.In figure Assembly be not necessarily to scale, and similar element numbers are conventionally used to indicate similar assembly.

First, term according to the present invention is suitably explained:" coil " refers to wire winding ringwise, Ke Yishi Other annulars such as conventional annular or round rectangle, and the number of turns of winding can be a circle or can be multi-turn, Wire winding can be fixed on support." around to " refers to that the winding of coil is the direction carrying out coiling in a clockwise direction, or Person carries out the direction of coiling in a counterclockwise direction.

Secondly, in conjunction with the drawings and specific embodiments, the present invention is further described.

First embodiment:

Refering to shown in Fig. 2 to Figure 12, the variable coil of this embodiment, including:One first coil 1, one second coil 2 and Switching device 3, this first coil 1 is connected by switching device 3 with this second coil 2, this switching device 3 be one can axis rotate Turnover structure, and there are two connection ends 31,32, the second end 12 of this first coil 1 and the first end 21 of this second coil 2 It is respectively connecting to two connection ends 31,32 of this switching device, the first end 11 of this first coil 1 is as the of this variable coil One connection end A1, the second end 22 of this second coil 2 is as the second connection end A2 of this variable coil.The First Line of this embodiment Circle 1 and the second coil 2 are identicals around to as a example (drawing counterclockwise around to).

Come below in conjunction with the accompanying drawings how to carry out couple state and non-coupled state by switching device 3 to this variable coil The operation principle of switching illustrate:

Refering to shown in Fig. 6 a and Figure 12 a, the first coil 1 of the variable coil of this embodiment and this second coil 2 be above, Lower position stacks (original state or use state).Refering to shown in Fig. 2, first coil 1 is open and flat turns over this for this second coil 2 Open, the second coil 2 on the right side of in figure be counterclockwise around to state, the first coil 1 on the left of in figure be counterclockwise around to.

Refering to shown in Fig. 3 and Fig. 4, the second coil 2 is overlapping with first coil 1 doubling, this can axis rotate turnover knot The switching device 3 of structure only turns down and does not axially rotate.Refering to shown in Fig. 5, the second coil 2 is overlapping with first coil 1 doubling Afterwards, the first coil 1 of the variable coil of this embodiment and the second coil 2 are in the use state stacking with upper and lower position, then The second end 22 being located at upside the second coil 2 after being turned down is located on first end 21.Now, the variable coil of this embodiment The second coil 2 and first coil 1 be respectively provided with identical around to (counterclockwise around to), constitute the shape of a similar complete coil State.Refering to shown in Fig. 6 a and 6b, this embodiment is placed under the electromagnetic field of an active coil as a passive coil, now should In the variable coil of embodiment, first coil 1 and the second coil 2 are in the different induction electromotive forces under identical induced field direction One end be connected, other one end of the different induction electromotive forces of this first coil and this second coil, can respectively as this Two connection ends of type transformer coil, thus the variable coil of this embodiment working condition on the whole is couple state.

It is assumed that above-mentioned state is under first state, when the second state is performed handover to by this switching device 3, such as Fig. 7 Shown, first have to open (with state as Fig. 2) by open and flat with this first coil 1 for this second coil 2 again, on the right side of in figure Two coil 2 be counterclockwise around to state, the first coil 1 on the left of in figure be counterclockwise around to.

Refering to shown in 8 and Fig. 9, this second coil 2 is rotated 180 °, then this can axis rotate turnover structure switching dress Put 3 by after 180 ° of axial rotation, refering to shown in Figure 10 and Figure 11 then this second coil 2 is overlapping with first coil 1 doubling.Ginseng Read shown in Figure 11, after overlapping with first coil 1 doubling for the second coil 2, the first coil 1 of the variable coil of this embodiment and Two coil 2 is in the use state stacking with upper and lower position, then turn down after being rotated 180 ° and be located at upside the second coil 2 First end 21 be located at the second end 22 on.

Now, the second coil 2 of the variable coil of this embodiment and first coil 1 are equally respectively provided with identical around to (inverse Hour hands around to).But, the first end 21 of the second coil 2 is now on the second end 22, the first end of the second coil 2 simultaneously 21 are still connected with the second end 12 of first coil 1, then refer to shown in Figure 12 a and 12b, and this embodiment is passive as one Coil is placed under the electromagnetic field of an active coil, now in the variable coil of this embodiment, at first coil 1 and the second coil 2 One end of identical induction electromotive force under identical induced field direction is connected, and this first coil is identical with this second coil Other one end of induction electromotive force, respectively as two connection ends of this variable coil, thus the variable coil of this embodiment Working condition on the whole is non-coupled state.

Supplementary notes, the first coil 1 of the above embodiments and the second coil 2 be identical around to (drawing inverse Hour hands around to) as a example illustrate, but first coil 1 and the second coil 2 can also be using contrary around to first coils 1 With the second coil 2 be contrary around in the case of, when first state or the second state are performed handover to by this switching device 3 The situation of the couple state of the variable coil of this embodiment or non-coupled state is just in contrast with the above description.

The variable coil of this embodiment can be applied to portable electronic terminal and (for example renovate torsion type electronics eventually End) in, first coil 1 is embedded in a part (body) for this terminal, the second coil 2 is embedded in another part (lid), This can axis rotate turnover structure switching device 3 as this two-part connector, then can be by the axis of active Rotate and turn down operation to realize for this terminal arranging coil couple state or non-coupled state, to improve safety.
