휴대용 단말기는 기본적으로 내장 배터리를 구비하여 이를 통해 전원을 공급받게 되는데, 휴대성을 강조한 나머지 본체 무게가 줄어듦과 동시에 배터리 사이즈가 작아지고 있는 추세이다. 물론 배터리 기술이 과거에 비해 많이 발달했지만 이와 함께 요구되는 전력량이 증가함으로써 외부에서 휴대용 전자기기를 장시간 사용할 때 배터리가 부족한 상황에 처하는 경우가 많다.The portable terminal is basically equipped with a built-in battery to receive power through it, the emphasis on portability, while the weight of the main body is reduced and the size of the battery is decreasing. Of course, battery technology has been developed more than in the past, but the amount of power required increases the battery shortage when using portable electronic devices for a long time from the outside.
이러한 문제를 방지하기 위하여, USB 포트 내지 전원 연결 단자에 결합될 수 있는 보조 배터리가 출시되고 있다. 하지만 보조 배터리는 휴대용 전자기기에 체결하여 사용하기에 모양새가 좋지 않고 일 측으로 돌출되어 있는 형태를 가지기 때문에 파지감 내지 사용 상태가 불편해진다는 단점이 있다.In order to prevent such a problem, a secondary battery that can be coupled to a USB port or a power connection terminal has been released. However, the auxiliary battery has a disadvantage in that it does not have a good grip and use state because the auxiliary battery has a shape that protrudes to one side and is not good in shape.

In this process, the size or shape of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, terms that are specifically defined in consideration of the configuration and operation of the present invention may vary depending on the intention or custom of the user or operator. Definitions of these terms should be made based on the contents throughout the specification.
도 1은 휴대용 단말기에 연결되는 보조 배터리를 나타낸 개략도이다.1 is a schematic diagram illustrating an auxiliary battery connected to a portable terminal.
도 1에 도시된 보조 배터리는 휴대용 단말기(200)가 거치되고 내부에 배터리가 마련된 거치대(30), 거치대(30)의 단부에 마련되고 휴대용 단말기(200)의 밑면에 형성된 커넥터(210)에 연결되는 충전 단자(10), 휴대용 단말기(200)가 거치대(30)로부터 이탈되는 것을 방지하는 지지대(50)를 포함할 수 있다.The auxiliary battery illustrated in FIG. 1 is mounted on the cradle 30 where the portable terminal 200 is mounted and provided with a battery therein, and is connected to the connector 210 formed at the end of the cradle 30 and formed on the bottom of the portable terminal 200. The charging terminal 10 may include a support 50 to prevent the portable terminal 200 from being separated from the holder 30.
휴대용 단말기의 밑면에 마련된 커넥터(210)는 휴대용 단말기를 구성하는 케이스에 홈의 형태로 마련되며, 이때, 홈의 깊이 방향을 따라 충전 단자(10)가 삽입되어야 한다. 즉, 제1 방향으로 홈의 깊이가 형성될 때 충전 단자(10) 역시 제1 방향으로 삽입되어야 한다.The connector 210 provided on the bottom of the portable terminal is provided in the form of a groove in the case constituting the portable terminal, and in this case, the charging terminal 10 should be inserted along the depth direction of the groove. That is, when the depth of the groove is formed in the first direction, the charging terminal 10 should also be inserted in the first direction.
이에 따라 보조 배터리에는 휴대용 단말기의 밑면측으로 돌출된 돌출부(70)가 마련될 수 있다. 충전 단자(10)는 돌출부(70)로부터 다시 제1 방향을 따라 돌출되도록 형성됨으로써 휴대용 단말기의 커넥터(210)에 연결될 수 있다. 휴대용 단말기의 커넥터(210)는 주배터리(270)의 충전 기능 뿐만 아니라 외부 기기와의 데이터 교환에도 사용된다. 따라서 충전 단자(10)로 인해 외부 기기와의 연결이 어려운 점을 감안하여 돌출부(70)에는 휴대용 단말기의 커넥터(210)와 전기적으로 연결되는 보조 커넥터(90)가 마련될 수 있다. 보조 커넥터(90)에 의하면 외부 기기와의 데이터 교환이 가능하다.Accordingly, the auxiliary battery may be provided with a protrusion 70 protruding toward the bottom of the portable terminal. The charging terminal 10 may be connected to the connector 210 of the portable terminal by being formed to protrude in the first direction again from the protrusion 70. The connector 210 of the portable terminal is used not only for the charging function of the main battery 270 but also for data exchange with an external device. Therefore, in view of the difficulty in connecting to an external device due to the charging terminal 10, the protrusion 70 may be provided with an auxiliary connector 90 electrically connected to the connector 210 of the portable terminal. According to the auxiliary connector 90, data exchange with an external device is possible.
돌출부(70)에 의하면 보조 배터리는 평면상으로 휴대용 단말기보다 큰 면적을 갖게 된다. 따라서, 보조 배터리에 휴대용 단말기를 장착시킨 상태로 사용시 휴대용 단말기의 실사용 크기가 증가하는 문제가 있다. 물론, 두께도 증가하게 될 것이다.According to the protrusion 70, the auxiliary battery has a larger area than the portable terminal in plan view. Therefore, there is a problem that the actual use size of the portable terminal increases when the portable terminal is mounted on the auxiliary battery. Of course, the thickness will also increase.
실사용시 휴대용 단말기의 크기가 확장되지 않도록 하는 것이 사용시 편리할 것은 자명하다.Obviously, it is convenient to use the portable terminal so that the size of the portable terminal is not extended in actual use.

도 2에 도시된 충전 장치는 휴대용 단말기의 배면에 형성된 전원 단자(290)에 연결되는 연결부(110) 및 연결부(110)를 통해 전원 단자(290)에 전력을 공급하는 배터리부(130)를 포함할 수 있다.The charging device illustrated in FIG. 2 includes a connection unit 110 connected to a power terminal 290 formed on a rear surface of the portable terminal and a battery unit 130 supplying power to the power terminal 290 through the connection unit 110. can do.
휴대용 단말기의 배면에는 착탈 가능한 배면 커버가 마련될 수 있다. 배면 커버는 휴대용 단말기의 배면에 설치되는 주배터리(270)의 교체 및 보호를 위한 것일 수 있다.The rear cover of the portable terminal may be provided with a removable back cover. The rear cover may be for replacement and protection of the main battery 270 installed on the rear of the portable terminal.
휴대용 단말기의 배면에는 주배터리(270)의 설치 공간(230), 주배터리(270)와 휴대용 단말기 본체와의 전기적 연결을 위한 주단자(250)가 마련될 수 있다. 이외에도 휴대용 단말기의 배면에는 주단자(250)와 별도로 마련되는 전원 단자(290)가 마련될 수 있다.The rear surface of the portable terminal may be provided with an installation space 230 of the main battery 270, the main terminal 250 for the electrical connection between the main battery 270 and the main body of the portable terminal. In addition, a power terminal 290 provided separately from the main terminal 250 may be provided on the rear surface of the portable terminal.
본 발명의 충전 장치는 휴대용 단말기의 배면에 형성된 전원 단자(290)에 전기적으로 연결되는 연결부(110)를 가질 수 있다. 일예로 연결부(110)는 전원 단자(290)에 직접 접촉되는 핀을 포함할 수 있다.The charging device of the present invention may have a connection portion 110 that is electrically connected to the power terminal 290 formed on the back of the portable terminal. For example, the connection unit 110 may include a pin directly contacting the power terminal 290.
연결부(110)는 휴대용 단말기의 배면에 마련된 전원 단자(290)에 연결되는 것이므로 휴대용 단말기의 앞에서 바라보았을 때 휴대용 단말기에 가려져 보이지 않는 위치에 마련된다.Since the connection unit 110 is connected to the power terminal 290 provided on the rear of the portable terminal, the connection unit 110 is provided at a position hidden from the portable terminal when viewed from the front of the portable terminal.
본 발명의 배터리부(130)는 연결부(110)를 통해 전원 단자(290)에 전력을 공급함으로써 휴대용 단말기의 배면측에 배치될 수 있다. 따라서, 정면에서 바라보았을 때 배터리부(130)가 휴대용 단말기의 본체에 가려지도록 휴대용 단말기에 배터리부(130)를 장착시킬 수 있다.The battery unit 130 of the present invention may be disposed on the rear side of the portable terminal by supplying power to the power terminal 290 through the connection unit 110. Therefore, when viewed from the front, the battery unit 130 may be mounted on the portable terminal such that the battery unit 130 is covered by the main body of the portable terminal.
본 발명의 충전 장치는 연결부(110) 및 배터리부(130)가 마련되는 커버부(150)를 포함할 수 있다. 배면 커버가 제거된 휴대용 단말기의 배면에 전원 단자(290)가 형성될 때, 커버부(150)는 배면 커버를 대체할 수 있다. 따라서 커버부(150)가 배면에 장착된 휴대용 단말기의 형태는 도 3과 같이 공장 출하시의 휴대용 단말기 형상과 동일할 수 있다.The charging device of the present invention may include a cover unit 150 in which the connection unit 110 and the battery unit 130 are provided. When the power terminal 290 is formed on the rear surface of the portable terminal from which the rear cover is removed, the cover unit 150 may replace the rear cover. Therefore, the shape of the portable terminal in which the cover unit 150 is mounted on the rear surface may be the same as the shape of the portable terminal at the time of shipment from the factory.
이와 같이 충전 장치로 휴대용 단말기의 배면 커버를 대체하게 되면 휴대용 단말기의 원래 형상을 거의 그대로 유지할 수 있으며, 배터리부(130)의 장착으로 인한 크기 확장을 최소화시킬 수 있다. 특히, 정면(휴대용 단말기의 디스플레이를 볼 수 있는 방향)에서 바라보았을 때 휴대용 단말기의 본체에 가려져 충전 장치가 보이지 않게 된다. 이러한 구성은 배터리부(130)의 출력단이 휴대용 단말기의 전원 단자(290)에 전기적으로 연결되도록 함으로써 가능하다. 또한, 이러한 구성에 따르면 소위 보조 배터리를 휴대용 단말기에 연결한 상태에서 휴대용 단말기의 커넥터(210)를 그대로 사용할 수 있는 이점이 있다.As such, when the rear cover of the portable terminal is replaced with the charging device, the original shape of the portable terminal can be maintained almost intact, and the size expansion due to the mounting of the battery unit 130 can be minimized. In particular, when viewed from the front (viewing direction of the portable terminal) is hidden by the main body of the portable terminal, the charging device is not visible. This configuration is possible by allowing the output terminal of the battery unit 130 to be electrically connected to the power terminal 290 of the portable terminal. In addition, according to such a configuration, there is an advantage in that the connector 210 of the portable terminal can be used as it is while the so-called auxiliary battery is connected to the portable terminal.
배터리부(130)는 외부 전원으로부터 공급된 전력을 저장하고, 저장된 전력을 전원 단자(290)로 공급하는 배터리를 포함할 수 있다. 이 경우 배터리부(130)를 충전시킬 수 있는 방안이 필요하다. 일례로서, 휴대용 단말기의 배면에 마련된 전원 단자(290)로부터 출력 전력을 공급받아 배터리부(130)를 충전시킬 수 있다. 다만, 이 경우에는 문제가 있을 수 있다. 휴대용 단말기의 배면에 마련된 전원 단자, 특히 무선 전력 수신용 단자는 오직 무선 전력을 수신하기 위해서만 존재하고 있으며, 그로 인해 휴대용 단말기의 내부 설계상 무선 전력 수신용 단자로부터 외부로 전력을 출력할 수 있도록 하는 기능은 존재하지 않을 수 있다. 본 발명에서는 휴대용 단말기의 배면에 마련된 전원 단자, 특히 무선 전력 수신용 단자가 외부로 전력을 출력시킬 수 있는 단자 역할을 겸할 수 있도록 하는 제3분배기를 휴대용 단말기에 마련함으로써 해결 가능하다. 즉, 이 휴대용 단말기는 기존에 알려진 구성에서, 외부 전원의 전력 수신을 위한 커넥터, 상기 휴대용 단말기의 배면에 형성된 무선 전력 수신용 단자, 및 상기 무선 전력 수신용 단자로부터 수신되는 전력을 휴대용 단말기의 주배터리로 분배 가능한 제3분배기를 포함하여 이루어지고, 상기 제3분배기는, 후면 커버 대체 가능한 충전 장치가 휴대용 단말기의 후면 커버로 장착되고 상기 커넥터로부터 외부 전력이 수신되면 상기 무선 전력 수신용 단자를 통해 상기 충전 장치에 전력을 제공하도록 전력 분배가 가능하게 구성함으로써 목적을 달성할 수 있다.The battery unit 130 may include a battery that stores power supplied from an external power source and supplies the stored power to the power terminal 290. In this case, a method for charging the battery unit 130 is required. As an example, the battery unit 130 may be charged by receiving output power from the power supply terminal 290 provided on the rear surface of the portable terminal. In this case, however, there may be a problem. A power terminal provided at the rear of the portable terminal, particularly a terminal for receiving wireless power, exists only for receiving wireless power, and accordingly, the internal design of the portable terminal enables output of power from the terminal for receiving wireless power to the outside. The function may not exist. According to the present invention, it is possible to solve the problem by providing a third divider in the portable terminal so that a power terminal provided on the rear surface of the portable terminal, in particular, a terminal for wireless power output can serve as a terminal for outputting power to the outside. That is, in the conventionally known configuration, the portable terminal includes a connector for receiving power of an external power source, a wireless power receiving terminal formed on a rear surface of the portable terminal, and a power received from the wireless power receiving terminal. And a third divider capable of distributing a battery, wherein the third divider includes a rear cover replaceable charging device mounted on the rear cover of the portable terminal and received external power from the connector. The purpose can be achieved by enabling power distribution to provide power to the charging device.
기존에 무선 전력 수신용 단자는 오직 무선 전력 수신을 위해서만 존재하고 있을 뿐 다른 용도로 사용하고자 하는 발상이 존재하지 않는다. 이러한 고정 관념을 탈피하였기에 본 발명은 더욱 가치가 있는 것이다.  Conventionally, a terminal for wireless power reception exists only for wireless power reception, and there is no idea to use it for other purposes. The present invention is more valuable because it breaks this stereotype.
본 발명의 또 다른 일실시예로서, 도 4는 본 발명의 충전 장치의 구성을 나타낸 개략도이다.As still another embodiment of the present invention, Figure 4 is a schematic diagram showing the configuration of the charging device of the present invention.
도 4의 충전 장치는 충전부 및 제1 분배부(140)를 포함할 수 있다.The charging device of FIG. 4 may include a charging unit and a first distribution unit 140.
충전부는 외부 전원이 연결되는 커넥터(120)를 포함할 수 있다. 이때, 커넥터(120)는 휴대용 단말기의 커넥터(210)와 같은 규격을 갖는 것이 좋다. 이에 따르면 휴대용 단말기에 적용되는 어댑터(정류 수단 포함)를 그대로 커넥터(120)에 적용할 수 있다.The charging unit may include a connector 120 to which an external power source is connected. At this time, the connector 120 may have the same specifications as the connector 210 of the portable terminal. According to this, the adapter (including the rectifying means) applied to the portable terminal can be applied to the connector 120 as it is.
제1 분배부(140)는 충전부로 입력된 전력을 배터리부(130) 및 연결부(110)로 분배할 수 있다. 이에 따르면 충전부에 어댑터를 연결하는 것으로 배터리부(130)와 휴대용 단말기의 주배터리(270)를 함께 충전할 수 있다.The first distribution unit 140 may distribute the power input to the charging unit to the battery unit 130 and the connection unit 110. Accordingly, by connecting the adapter to the charging unit, the battery unit 130 and the main battery 270 of the portable terminal can be charged together.

The power supply terminal 290 is a terminal supplied with external power to the main body of the portable terminal. However, when the power providing unit 220 for supplying power to the power terminal 290 is provided in the portable terminal, power may be supplied to the outside through the power terminal 290. The sensing unit 160 senses the output power of the power terminal 290 at this time, so that the power terminal 290 supplies power through an adapter connection or the like whether the power terminal 290 is receiving power from the battery unit 130. It can be determined whether or not.
공급부(180)는 전원 단자(290)의 출력 전력이 설정값을 만족하면 전원 단자(290)의 출력 전력을 배터리부(130)로 공급할 수 있다. 이에 따르면 휴대용 단말기에 어댑터를 연결하는 것으로 배터리부(130)와 휴대용 단말기의 주배터리(270)를 함께 충전할 수 있다.The supply unit 180 may supply the output power of the power terminal 290 to the battery unit 130 when the output power of the power terminal 290 satisfies the set value. Accordingly, by connecting an adapter to the portable terminal, the battery unit 130 and the main battery 270 of the portable terminal can be charged together.
정리하면, 배터리부(130)는 전원 단자(290)의 출력 전력 또는 외부 전원이 연결되는 충전부의 출력 전력으로 충전될 수 있다. 한편, 도 4와 도 5의 구성은 함께 이루어질 수 있다.In summary, the battery unit 130 may be charged with the output power of the power terminal 290 or the output power of a charging unit to which an external power source is connected. On the other hand, the configuration of Figure 4 and 5 can be made together.

전력 수신부(190)는 외부 전원으로부터 무선으로 전력을 수신할 수 있다. 일예로 전력 수신부(190)는 외부 전원으로부터 자기 유도 방식 또는 자기 공명 방식으로 전력을 수신하는 코일을 포함할 수 있다.The power receiver 190 may wirelessly receive power from an external power source. For example, the power receiver 190 may include a coil for receiving power from an external power source in a magnetic induction method or a magnetic resonance method.
제2 분배부(170)는 전력 수신부(190)의 출력 전력을 배터리부(130) 및 연결부(110)로 분배할 수 있다. 이에 따르면 배터리부(130) 및 휴대용 단말기의 주배터리(270)에 대한 소위 무선 충전이 가능하다.The second distribution unit 170 may distribute the output power of the power receiver 190 to the battery unit 130 and the connection unit 110. Accordingly, the so-called wireless charging of the battery unit 130 and the main battery 270 of the portable terminal is possible.

It may include a front cover extending from) and covering the display provided on the front of the portable terminal.
전면 커버에서 커버부(150)에 연결되는 부위는 플렉시블하게 형성할 수 있다. 이때, 플렉시블한 부위로 인해 전면 커버가 갖는 자유도는 휴대용 단말기의 길이 방향을 회전축으로 하는 회전 자유도일 수 있다.A portion of the front cover connected to the cover portion 150 may be formed flexibly. In this case, the degree of freedom of the front cover due to the flexible portion may be a rotational degree of freedom of the longitudinal direction of the portable terminal.
도 7의 충전 장치에 의하면 휴대용 단말기에 추가적인 배터리를 제공하는 동시에 휴대용 단말기의 배면뿐만 아니라 전면을 신뢰성 있게 보호할 수 있다.According to the charging device of FIG. 7, an additional battery may be provided to the portable terminal and at the same time, the front surface of the portable terminal may be reliably protected.

Can supply Accordingly, it is possible to increase the use time of the portable terminal, to provide a beautiful appearance and at the same time miniaturization.
본 발명의 충전 장치는 휴대용 단말기의 배면에 착탈되면 충분하고, 반드시 휴대용 단말기의 배면 커버를 대체할 필요는 없다. 이와 같은 경우라 하더라도 정면에서 바라봤을 때 휴대용 단말기의 크기 증가는 없다.It is sufficient that the charging device of the present invention is attached to and detached from the back of the portable terminal, and it is not necessary to replace the back cover of the portable terminal. Even in this case, there is no increase in the size of the portable terminal when viewed from the front.
한편, 앞에서 살펴본 충전 장치가 신뢰성 있게 동작하기 위해서는 연결부(110)가 휴대용 단말기의 전원 단자(290)에 신뢰성 있게 접촉되어야 한다. 이를 위해 연결부(110)는 접촉부(113), 탄성부(115)를 포함할 수 있다.Meanwhile, in order for the charging device described above to operate reliably, the connection unit 110 must reliably contact the power terminal 290 of the portable terminal.
