The receiver 200 is preferably installed in any one of the band 13 and the speaker unit 11 to be in contact with the transmitter 100. It is most preferable that the receiver 200 is installed in the band 13 as shown in FIG. , But is not limited thereto.

The receiver 200 is connected to a battery B of a power storage, that is, a device under test (DUT), to charge the battery and supply driving energy of the electronic device.

At this time, the battery is present together with the receiver 200 or exists in an electrically connected area (for example, the speaker unit 11), and such a battery is a usual one, and a description thereof will be omitted.

As described above, the transceiver includes a transmitter 100 connected to an AC power source through an adapter 150, a transmitter 100, and a receiver 200 receiving power wirelessly.

3 is a schematic diagram illustrating a transmitter according to a preferred embodiment of the present invention.

The transmitter 100 in the charging wireless transmission apparatus of the present invention includes a coil 111, a ferrite sheet 113 as a magnetic substance sheet, and a suscef frame 115 (SUS Frame) as a metallic plate The control unit 110 may include a coil unit 110 arranged in an up-down direction, a coil unit 110 disposed on a side surface of the coil unit 110, A film 140 selectively applied and attached to the top of the coil section 110 and optionally an injection section 120 molded in an area other than above the coil section 110, .

In the above-mentioned area, it is noted that the magnetic sheet and the metallic plate are denoted by common words. However, it should be noted that the present invention is represented by a ferrite sheet and a suscef frame according to an embodiment, do.

The coil 111 is for wireless transmission, and the ferrite sheet 113 serves to maximize the directionality of the magnetic field generated in the coil by transmitting power to the upper part and blocking power leakage to the lower part. In addition, the sus frame 115 is also for improving the directionality of the electromagnetic wave generated by the coil.

Here, the ferrite sheet 113 may be replaced with another material having magnetism. That is, since amorphous metal, soft magnetic material, or ferromagnetic material can be used, the material of the upper sheet is not limited to ferrite alone.

In addition, the suscef frame 115 is a metallic plate, which is installed not only to perform the above functions but also to reinforce the rigidity of the device to establish the reliability of the product. However, the suscepter 115 is not limited thereto. Therefore, the suscef frame 115 may be made of a material substituting for phosphor bronze, gold, silver, copper, or aluminum.

The ferrite sheet 113 and the sus frame 115 have a common function in improving radiation efficiency, which is a very important concept in the field of wireless power transmission.

In order to further impart magnetism to the suscef frame 115, a magnetic substance may be further coupled or a magnetic substance may be further coated on a part or the whole of the suscepter 115. This may double the efficiency of power transmission for wireless charging It is expected to be able to carry out.

The method of imparting magnetism to the suscef frame 115 is preferably a coating, which is to make the thickness of the suscef frame 115 as thin as possible. Thus, by coating the amorphous metal or the like, 115). When the amorphous metal is coated in this way, it is preferable to apply the ferrite sheet, which is a material different from amorphous metal, for example, when the magnetic sheet is used. However, the use of amorphous metal as the magnetic substance sheet and the coating of the amorphous metal to further impart magnetism to the suscef frame 115 is to double coat the amorphous metal on the suscef frame 115, It is not.

The ferrite sheet 113 is bonded to the coil part 110 and the metallic plate 115 by a lamination method, while the amorphous metal, which replaces the ferrite sheet 113, 110 or the upper portion of the metallic plate 115, the forming method of the laminated structure may be somewhat different depending on the material.

The injection part 120 constituted by the present invention is formed by an insert injection method using the coil part 110 and the control part 130 as a matrix. Here, the formation of the injection portion with respect to the coil portion 110 may be partially or entirely excluded.

In the case of using the insert injection method as described above, it is possible to inject the coating type, thereby making it possible to make the thickness of the product itself slimmer.

Such insert injection can be insert injection using only the chassis frame 115 as a matrix. In other words, it is also possible to form the injection part with the sus frame 115 as an insert. In particular, it is possible to use the insert injection method by forming the injection part 120 only on the opposite side of the susceptor frame 115 in the coil direction.

It is possible to form the injection part 120 only on one side of the coil part by performing the lamination of the ferrite sheet 113 and the coil 111 on the surface of the chassis frame 115 on which the injection part 120 is not formed will be.

Meanwhile, the injection part 120 may be omitted from the coil part 110. That is, the coil part 110 may or may not form the injection part 120 locally or globally.

When the formation of the injection part 120 is excluded from the coil part 110, the injection part 120 is provided only in the control part 130. Since the control part 130 requires external protection means, The injection unit 120 must be provided in the control unit 130 even if the injection unit 120 is not formed.

The present invention has the advantage of smooth power transmission to the receiver 200 by excluding the injection part 120 from the coil part 110 which is a direct means of power transmission. In other words, in the related art, the injection unit 120 must be provided over the entire apparatus, and therefore, the overall thickness is increased to limit the transmission / reception performance. However, the present invention can be applied to an upper outer tube portion, The adhesion state between the transmitter 100 and the receiver 200 is maximally maintained with the film 140 interposed therebetween, so that the effect of power transmission can be doubled.

Here, the film 140 serves as an upper outer tube for sealing the upper part of the coil part. Therefore, the material and shape of the upper outer tube portion need not necessarily be film, but if the thickness of the wireless transceiver is reduced, the shape of the film is preferable to other bulk state inclusions.

At this time, the film 140 is attached to the upper part of the transmitter 100 or the coil part 110 of the receiver 200, and is preferably a PC film (Polycarbonate film).

However, it is also possible to use PI (Polyimide), PET (Polyethylene Terephthalate) or the like in addition to the PC film.

The above film can be formed by various methods such as an insert method, a painting method, a coating method, a deposition method, and the like, as well as the above-described attachment method to the coil part. Therefore, the way of forming the film 140 should not be limited.

Meanwhile, the coil part 110 may be manufactured first as an independent module, and a detailed description thereof will be described with reference to FIG.

4 is a schematic diagram for explaining an example of a transmitter according to a preferred embodiment of the present invention.

As shown in the figure, the transmitter 100 includes a first injection unit 121 for molding a coil part 110 as a matrix, a control part 130 disposed on a side surface of the coil part 110 as a matrix, The first injection part 121 and the second injection part 123 are preferably formed by insert injection molding. The first injection part 121 and the second injection part 123 are formed by injection molding.

By performing the insert injection with the coil part 110 as a mother body in this way, the coil part 110 can be modularized. Therefore, when at least the coil part 110 is defective, the economic effect Can be expected. In other words, in the related art, since all the components are stacked at the time of occurrence of errors in the coil part 110 or the control part 130, they have to be replaced with each other. However, according to the present invention, . Therefore, the economical efficiency of device maintenance is expected.

5 is a plan view showing a configuration of a control unit according to a preferred embodiment of the present invention.

As shown in the drawings, the control unit of the present invention can be installed side by side on one side of the coil part, and (b) can be installed radially around the coil part. However, both of these two embodiments have a commonality in that a control portion is provided on the side of the coil portion, and the configuration is somewhat different.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.
