Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a removable wireless charging apparatus and a set-top box having the wireless charging apparatus removably incorporated therein,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wireless charging device for supplying power to an external mobile device in a non-contact manner by being supplied with power from a set-top box in a state of being detachably incorporated into a set-

More particularly, the present invention relates to a portable wireless charging device, and more particularly, to a portable wireless charging device, in which one side of a set-top box is opened so as to correspond to such a removable wireless charging device, To a set-top box.

Generally, a set-top box (digital set-top box) is a digital broadcast receiving apparatus that receives a digital broadcast provided through a terrestrial wave, a cable, a satellite, and an IP network and displays it through a display device (monitor, television set). Such a set-top box is configured for each digital broadcasting company and generally comprises a configuration for receiving digital broadcasting transmitted by the broadcasting company.

On the other hand, various types of mobile terminals including smart phones are rapidly spreading, and techniques for charging these mobile terminals have also been proposed. In the past, adapters that could charge mobile terminals by household power were common, but after Apple's iPhone in the United States, charging the mobile terminal by drawing power from the USB port is also widely used.

The mobile terminal employs a proprietary access port for each manufacturer, which makes charging very inconvenient in actual use environments. As an example of a general household, there are various types of mobile terminals according to their preferences according to their members, so it is inconvenient to provide an adapter or a charging cable for each terminal manufacturer in the house, and to adjust them at that time. The adapters can be provided in one and the gender for port conversion can be used, but the inconvenience is still present in this case.

Recently, a wireless charging technique has been proposed in order to solve the above problems and basically to solve the inconvenience of cable connection. There are three proposals to transmit power wirelessly using electromagnetic induction, electromagnetic resonance, and electromagnetic waves. Electromagnetic induction and electromagnetic resonance are considered to be a major factor in the charging of mobile terminals. The electromagnetic induction method is suitable for this purpose because it transmits power at distances of several mm to several cm with 125 kHz and 135 kHz signals, and the electromagnetic resonance method transmits electric power at distances of several meters or less with a 10 MHz signal.

The electromagnetic induction method has been established by the Wireless Power Consortium (WPC), which was launched in 2008, and the technical specification 1.0 was announced in 2010, and it has proved to be somewhat effective. Accordingly, recently, an electromagnetic induction type wireless rechargeable pad according to the WPC standard has been introduced, but it is very expensive and difficult to be used by ordinary users.

The electromagnetic resonance method was developed by Professor M. Soljacic of MIT in 2007 and is focused on commercialization in Intel, Qualcomm and Sony. In particular, Qualcomm has proven to be somewhat effective as it develops prototypes that can charge two phones simultaneously at 20cm distances. The electromagnetic charging type wireless charging device has not yet been released, but even if it is released, it is expected to be very expensive, making it difficult for general users to use.

The core block 200 is fixed to the upper surface of the base plate 100 while being seated on the upper surface of the rear end of the base plate 100. The operation of the wireless charging device for non-contact charging is determined according to the distance between the power feeding coil 300 wound on the upper surface of the core block 200 and the ceiling of the housing. 300 can be adjusted in height.

The power supply coil 300 is electrically connected to the set-top box so as to supply electric power to the external mobile device, which is wound around the core block 200 in an endless track form and downwardly from the top of the core block 200 .

The PCB substrate 400 is fitted into the depressed portion of the base plate 100 and is seated and controls power to be supplied to an external mobile device when an external mobile device approaches downward from the top of the core block 200.

The GND terminal of the PCB substrate 400 with respect to the external operation power supplied to the PCB 400 is connected to the male connector of the base plate 100 via the heat sink 500, Stabilizing and reducing electrical noise. The PCB that controls the operation of the wireless charging device itself is grounded to an external terminal and a plurality of lines when power is supplied from the outside. At this time, the GND voltage is irregular at a plurality of grounded contacts, and electrical noise (EMI) Can be overcome.

The heat sink 500 is configured to be seated on the upper surface of the base plate 100 so as to surround the core block 200 from the undersurface of the base block 100. The heat sink 500 effectively dissipates heat generated from the core block 200, The magnetic field generated in the vicinity of the feed coil 300 is blocked from being transferred to the set-top box when an external mobile device approaches the core block 200. [

The ground GND of the PCB substrate 400 with respect to the external operation power supplied to the PCB 400 is connected to the male connector of the base plate 100 via the heat sink 500 to reduce electrical noise .

The finishing plate 600 is integrally connected to the base plate 100 at the front end of the base plate 100 and closes the open portion of the set-top box in which the base plate 100 protrudes and retracts.
