무선수신모듈(31)은 무선충전패드(300)와 같은 외부 전원 제공모듈로부터 전원을 무선으로 수신하는 모듈이다. 이를 위해 무선수신모듈(31)은 코일(미도시)을 포함하고 코일을 이용하여 무선전력전송기술을 구현한다. 무선전력전송기술은 이미 공지된 기술임에 따라 자세한 설명은 하지 않도록 한다. 한편 무선수신모듈(31)은 본체(10)의 외면에 설치됨에 따라 무선충전패드(300)와의 사이에 임의의 물질을 배제시킬 수 있다. 즉 무선수신모듈(31)은 높은 효율로 충전 에너지를 수신할 수 있다. The wireless receiving module 31 is a module that wirelessly receives power from an external power supply module such as the wireless charging pad 300. To this end, the wireless receiving module 31 includes a coil (not shown) and implements wireless power transmission technology using the coil. Since the wireless power transmission technology is a well-known technology, it will not be described in detail. On the other hand, as the wireless receiving module 31 is installed on the outer surface of the main body 10, any material may be excluded from the wireless charging pad 300. That is, the wireless receiving module 31 can receive charging energy with high efficiency.
인터페이스모듈(33)은 유선 아답터, USB(universal serial bus)와 같은 외부 전원 제공모듈로부터 전원을 유선으로 수신하는 모듈이다. 이를 위해 인터페이스모듈(33)은 다양한 종류의 포트를 포함할 수 있다.The interface module 33 is a module that receives power by wire from an external power supply module such as a wired adapter or a universal serial bus (USB). To this end, the interface module 33 may include various types of ports.
제2 연결부(35)는 무선수신모듈(31) 및 인터페이스모듈(33)과 연결되고, 무선수신모듈(31) 및 인터페이스모듈(33)로부터 수신된 충전 에너지를 제어부(50)로 전달한다. 제2 연결부(35)는 무선수신모듈(31) 및 인터페이스모듈(33)와 제어부(50) 사이를 연결하는 매개체 역할을 수행한다.The second connection unit 35 is connected to the wireless reception module 31 and the interface module 33, and transfers the charging energy received from the wireless reception module 31 and the interface module 33 to the control unit 50. The second connection unit 35 serves as an intermediary connecting the wireless reception module 31 and the interface module 33 and the control unit 50.
제어부(50)는 본체(10)의 내부에 설치되고, 충전 에너지가 수신되면 충전 에너지를 승압한다. 이를 위해 제어부(50)는 승압모듈(51)을 포함한다. 승압모듈(51)은 충전 에너지를 승압시키는 기능을 수행하며, 이를 통해 외부전원으로부터 수신되는 과정에서 충전 에너지의 전압이 떨어지는 현상을 보완하여 충전율을 높일 수 있다. 제어부(50)는 승압된 충전 에너지를 송신부(70) 또는 배터리(90)로 전송할 수 있다. 이때 승압모듈(51)은 송신부(70)로 전송하는 충전 에너지의 승압 크기와 배터리(90)로 전송하는 충전 에너지의 승압 크기를 서로 다르게 제어할 수 있다. 즉 승압모듈(51)은 송신부(70) 및 배터리(90)에서 원하는 스펙의 전압으로 승압시킬 수 있다. 예를 들어 외부전원으로부터 수신된 충전 에너지의 전압보다 배터리(90)에서 원하는 스펙의 전압이 높고, 배터리(90)에서 원하는 스펙의 전압보다 송신부(70)에서 원하는 스펙의 전압이 높을 수 있다.The control unit 50 is installed inside the main body 10, and when charging energy is received, the charging energy is boosted. To this end, the control unit 50 includes a boosting module 51. The boosting module 51 performs a function of boosting the charging energy, and through this, compensates for the phenomenon in which the voltage of the charging energy falls in the process of receiving it from an external power source, thereby increasing the charging rate. The control unit 50 may transmit the boosted charging energy to the transmitting unit 70 or the battery 90. At this time, the boosting module 51 may control the boosting size of the charging energy transmitted to the transmitter 70 and the boosting size of the charging energy transmitted to the battery 90 differently. That is, the boosting module 51 may boost the voltage of a desired specification in the transmitter 70 and the battery 90. For example, the voltage of the desired specification in the battery 90 is higher than the voltage of the charging energy received from the external power source, and the voltage of the desired specification in the transmitter 70 may be higher than the voltage of the desired specification in the battery 90.
송신부(70)는 본체(10) 중 사용자 단말(200)과 대향하는 부분에 설치된다. 송신부(70)는 코일(미도시)을 포함하고 코일을 이용하여 무선전력전송기술을 구현한다. 한편 송신부(70)는 사용자 단말(200)과 밀착되도록 설치됨에 따라 사용자 단말(200)과의 사이에 임의의 물질을 배제시킬 수 있다. 즉 송신부(70)는 높은 효율로 충전 에너지를 전송할 수 있다. The transmitter 70 is installed in a portion of the main body 10 facing the user terminal 200. The transmitter 70 includes a coil (not shown) and implements a wireless power transmission technology using the coil. Meanwhile, as the transmitter 70 is installed to be in close contact with the user terminal 200, any material may be excluded from the user terminal 200. That is, the transmitter 70 can transmit charging energy with high efficiency.
배터리(90)는 본체(10)에 결합되어 승압된 충전 에너지가 저장된다. 배터리(90)는 충방전이 가능한 이차전지로 형성된다. 배터리(90)는 본체(10)와의 분리가 가능하여 불필요한 경우 분리하여 단말 케이스(100)의 무게를 줄일 수 있고, 배터리가 오래되어 에너지 저장률이 낮은 경우 교체할 수 있다. The battery 90 is coupled to the main body 10 to store the boosted charging energy. The battery 90 is formed of a secondary battery that can be charged and discharged. The battery 90 can be separated from the main body 10 to remove the weight of the terminal case 100 by removing it if unnecessary, and can be replaced when the battery is old and the energy storage rate is low.
도 5는 본 발명의 제1 실시예에 따른 단말 케이스의 구동을 설명하기 위한 도면이고, 도 6은 본 발명의 제2 실시예에 따른 단말 케이스의 구동을 설명하기 위한 도면이다.5 is a view for explaining the driving of the terminal case according to the first embodiment of the present invention, Figure 6 is a view for explaining the driving of the terminal case according to the second embodiment of the present invention.
도 5 및 도 6을 참조하면, 단말 케이스(100)는 기 설정된 기준에 따라 구동할 수 있다. 5 and 6, the terminal case 100 may be driven according to a preset criterion.
예를 들어 사용자 단말(200)의 충전율이 기 설정된 기준보다 낮고, 충전 에너지가 수신되는 경우, 제어부(50)는 수신된 충전 에너지를 승압한 후, 승압된 충전 에너지를 사용자 단말(200)로 전송되도록 제어한다. 여기서 사용자 단말(200)의 충전율에 대한 기 설정된 기준은 60% 내지 80%일 수 있다. 이때 충전 에너지를 수신하는 방법은 두 가지가 있으며, 하나는 무선수신모듈(31)을 통해 무선으로 충전 에너지를 수신하는 방법이고, 나머지 하나는 인터페이스모듈(33)을 통해 유선으로 충전 에너지를 수신하는 방법이다. 이때 충전 에너지는 연결부(35)를 통해 제어부(50)로 전달할 수 있다.For example, when the charging rate of the user terminal 200 is lower than a preset criterion and charging energy is received, the control unit 50 boosts the received charging energy and then transmits the boosted charging energy to the user terminal 200 Control it as much as possible. Here, the preset criterion for the charging rate of the user terminal 200 may be 60% to 80%. At this time, there are two methods of receiving charging energy, one is a method of receiving charging energy wirelessly through the wireless receiving module 31, and the other is a method of receiving charging energy by wire through the interface module 33. It is a way. At this time, the charging energy may be transmitted to the control unit 50 through the connection unit 35.
사용자 단말(200)의 충전율이 기 설정된 기준보다 높고, 배터리(90)의 충전율이 기 설정된 기준보다 낮으며, 충전 에너지가 수신되는 경우, 제어부(50)는 수신된 충전 에너지를 승압한 후, 승압된 충전 에너지를 배터리(90)에 충전되도록 제어한다. 여기서 배터리(90)의 충전율에 대한 기 설정된 기준은 60% 내지 80%일 수 있다.When the charging rate of the user terminal 200 is higher than a preset criterion, the charging rate of the battery 90 is lower than a preset criterion, and when charging energy is received, the control unit 50 boosts the received charging energy and then boosts it. The charged energy is controlled to be charged in the battery 90. Here, the preset criterion for the charging rate of the battery 90 may be 60% to 80%.
사용자 단말(200)의 충전율이 기 설정된 기준보다 낮고, 충전 에너지가 미수신되는 경우, 제어부(50)는 배터리(90)에 저장된 저장 에너지를 충전 에너지로 사용하도록 제어한다. 이때 제어부(50)는 저장 에너지를 승압모듈(51)을 통해 승압시켜 충전 에너지로 사용할 수 있다. 즉 제어부(50)는 저장 에너지의 전압이 송신부(70)로 전송할 수 있을 정도의 전압으로 승압시켜 충전 에너지로 사용한다.When the charging rate of the user terminal 200 is lower than a preset criterion and the charging energy is not received, the controller 50 controls to use the stored energy stored in the battery 90 as charging energy. In this case, the control unit 50 may use the stored energy as charging energy by boosting it through the boosting module 51. That is, the controller 50 boosts the voltage of the stored energy to a voltage that can be transmitted to the transmitter 70 and uses it as charging energy.
