Until now, wireless charging has been implemented such that the wireless charging device is placed on a transmitter (typically in the form of a pad) provided with the wireless charging device. As a result, if the receiver of the wireless charging device deviates from the transmission area where wireless charging is allowed, the wireless charging is not performed or the efficiency is extremely low.

In addition, when the transmitter of the wireless charging apparatus is placed on a floor or a desk, the wireless charging apparatus including the transmitter is not securely fixed, and the transmitter and the receiver of the wireless charging apparatus are separated from each other due to impact and fine movement. there was.

In addition, the present wireless charging device can charge only one wireless charging device in the transmitter of one wireless charging device, which has a limitation in that compatibility with requiring a dedicated wireless charging device for each wireless charging device is low.

Accordingly, the present invention provides a loop type in which a wireless charging device can be charged wirelessly in a loop or a loop anywhere in a loop, regardless of the direction, and a plurality of wireless charging devices can be charged in a single wireless charging device, And a wireless charging device that is integrated with the plug to reduce power loss.

Meanwhile, the wireless charger to be described below includes a general portable device, but the present invention is not limited thereto, and it can be said that the wireless charger may include a household electric appliance to which a wireless charging technology is applied.

The wireless charging unit 122 may include a storage unit capable of storing a wireless charging device (for example, a smart phone or the like), and can wirelessly supply power to the wireless charging device stored in the storage unit. Although the term " housed " is used for the convenience of description of the present invention, the housing and housing part to be described below are not limited to the concept that all of the outer shape of the wireless charging device is located inside the wireless charging part 122, And includes a concept that a part of the external shape is placed and mounted inside the wireless charging unit 122. [

Here, there is at least one wireless charging device stored in the storage portion, and a plurality of wireless charging devices can be accommodated according to the size and shape of the storage portion. As a result, the loop type plug-integrated multi-function wireless charging device 120 according to the present invention can charge a plurality of wireless charging devices at the same time in one wireless charging device 120.

The plug 121 is inserted into and electrically connected to an external power outlet 110 and can receive power from the power outlet 110 and transmit power to the wireless charging unit 122.

In particular, the plug 121 and the wireless charger 122 included in the loop-shaped plug-integrated multi-wireless charging apparatus 120 according to the present invention may be integrally formed. Through such an integrated structure, the loop-shaped plug-integrated multi-function wireless charging apparatus 120 according to the present invention can reduce the power loss caused by the conventional wireless charging apparatuses connected to the charger and the power outlet by electric wires or the like .

Meanwhile, the receiving part provided in the wireless charger 122 may be formed in a loop shape (see FIG. 2) or a cylindrical shape (FIG. 1) including a loop shape and a wireless charger can be housed therein. It should be understood, however, that the present invention is not limited to the above-described embodiments.

The loop type plug-integrated multi-wireless charging apparatus 120 according to the present invention can adjust the size of the loop shape of the receiving portion or the depth of the cylindrical shape, thereby controlling the amount of power transmitted to the wireless charger And the number of wireless charging equipments housed in the receiving portion can also be controlled.

The loop-shaped plug-integrated multi-wireless charging apparatus 120 according to the present invention can be installed in the inside of the loop and the loop- Such as at least one of the top of the loop, to wirelessly power the wireless charger.

Referring to FIG. 2, the loop type plug-integrated multi-wireless charging apparatus 220 includes a plug 221 and a wireless charging unit 222 electrically connected to a power outlet 210 provided on a wall surface 200.

The plug 221, the external wall surface 200, and the power source outlet 210 of the loop type plug-integrated multi-function wireless device 220 of FIG. 2 are as described above with reference to FIG.

In particular, the loop-shaped plug-integrated multi-wireless charging apparatus 220 of FIG. 2 is substantially similar to the plug-integrated multi-wireless charging apparatus 120 of the loop configuration of FIG. 1, but the form of the storage unit, (FIG. 2) rather than a form (FIG. 1).

That is, the housing part can be manufactured in various forms, and it suffices that at least one or more wireless chargers are accommodated in the housing and can transmit power from the wireless charger unit to the wireless charger wirelessly. However, considering the efficiency of wireless charging, the shape of the closed form is preferable even if the form is various.

On the other hand, the receiving unit of the wireless charging units 122 and 222 wirelessly charges the wireless charging device, and can store various wireless charging devices. In particular, the receiving portion can be detachably mounted to the wireless chargers 122 and 222. [

In this case, depending on the wireless charging method of the wireless charging device, the accommodating portion including the wireless charging type wireless charging module corresponding to the charging method can be exchanged with the wireless charging portions 122 and 222. [ For example, when the wireless charging method of the wireless charging module included in the wireless charging units 122 and 222 is the magnetic induction method and the wireless charging method of the wireless charging device to be wirelessly charged is the magnetic resonance method , The receiving portion including the wireless charging module of the magnetic induction type may be detached from the wireless charging portions 122 and 222 and then the receiving portion including the wireless charging module of the magnetic resonance type may be replaced with the wireless charging portions 122 and 222 .

In addition, the wireless charging method of the wireless charging module of the storage unit installed in the wireless charging units 122 and 222 is a wireless power consortium (WPC) scheme among the magnetic induction scheme, and the wireless charging scheme of the wireless charging device In the case of the PMA (Power Matrix Alliance) scheme, the receiver including the wireless charging module of the WPC scheme is detached from the wireless chargers 122 and 222, and then the receiver including the wireless charging module of the PMA scheme is connected to the wireless charger 122, and 222, respectively. The wireless charging method of the wireless charging module may be any of a magnetic induction method (WPC method and PMA method), a magnetic resonance method, and an electromagnetic wave method. However, the present invention is not limited thereto, and the wireless charging method of the wireless charging module included in the accommodation portion may be various wireless charging methods (including a wireless charging method to be developed in the future).

As a result, the loop-shaped plug-integrated multi-wireless charging apparatus according to the present invention can charge the wireless charger in either a loop or a loop anywhere, regardless of the direction, and can charge multiple wireless chargers simultaneously from one wireless charger And can be integrated with the plug and fixed to the wall with minimal power loss.

Accordingly, the foregoing detailed description should not be construed in any way as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
