이하 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2에는 본 발명의 실시예에 의한 휴대용 전원 공급 장치를 전동공구에 연결한 모습을 보인 사시도가 도시되어 있다.FIG. 2 is a perspective view showing a portable power supply device according to an embodiment of the present invention connected to a power tool.
본 발명의 실시예에 의한 휴대용 전원 공급 장치는, 전동공구와 같은 휴대용 전자 기기(1)에 연결하여 전원을 공급하기 위한 배터리 또는 보조 배터리로써 사용될 수 있으며, 배터리 팩(100), 연결 케이블(200), 접속커버(300)를 포함한다.The portable power supply apparatus according to an embodiment of the present invention can be used as a battery or an auxiliary battery connected to a portable electronic device 1 such as a power tool to supply power, And a connection cover 300, as shown in Fig.
휴대용 전자 기기(1)는 전동공구, 전기 자전거, 노트북 등 다양한 휴대용 전자 기기가 해당할 수 있으나, 본 실시예에서는 전동공구를 예로 들어 설명한다.The portable electronic device 1 may be a variety of portable electronic devices such as a power tool, an electric bicycle, and a notebook computer. In the present embodiment, a power tool is taken as an example.
도 2에 도시된 바와 같이, 배터리 팩(100)은 충전지와 회로기판이 내장되며 외관을 육면체 형상의 케이스가 형성한다. 케이스는 메인 케이스와 메인 케이스의 상부 측과 하부 측에 각각 커버가 결합된 형상일 수 있다.As shown in FIG. 2, the battery pack 100 includes a rechargeable battery and a circuit board, and a case having a hexahedral shape is formed on the outer surface. The case may have a shape in which a cover is coupled to the upper side and the lower side of the main case and the main case, respectively.
충전지는 이미 방출된 전류를 다시 외부로 유입시켜 전압이 회복되는 전지로서, 외부로부터 유입되는 전류에 의해 충전된 전압을 다른 휴대용 전자 기기(1)에 공급할 수 있는 배터리이다.The rechargeable battery is a battery in which a voltage is restored by introducing a current that has already been discharged to the outside, and is a battery capable of supplying a voltage charged by a current flowing from the outside to another portable electronic device (1).
충전지는 리튬이온(Li-ion) 배터리로 된다. The rechargeable battery is a lithium-ion (Li-ion) battery.
리튬이온 배터리는 니켈카드뮴(Ni-Cd) 배터리나 리튬인산철(LiFePO4) 배터리에 비해 안정적이고 출력이 높으며 에너지 밀도가 2배 이상 높아 더 적은 양과 사이즈로 더 많은 전기 에너지를 저장할 수 있어, 배터리 팩(100)의 부피를 줄일 수 있고 무게를 감소시켜 배터리 팩(100)을 작업자가 휴대하기 용이하게 할 수 있다.Lithium-ion batteries are more stable, more powerful, and more energy-efficient than nickel-cadmium (Ni-Cd) or lithium-iron phosphate (LiFePO 4 ) batteries and can store more electrical energy in smaller quantities and sizes, The volume of the pack 100 can be reduced and the weight of the pack 100 can be reduced, thereby facilitating the carrying of the battery pack 100 by an operator.
리튬이온 배터리는 리튬인산철 배터리에 비해서는 충전시간이 오래 걸리나, 이로 인해 충전시 발열 문제가 없어 방열 구조를 포함하지 않고 배터리 팩을 제작할 수 있고 배터리 팩(100)의 무게를 최소화할 수 있다.The lithium ion battery requires a longer charging time than the lithium iron phosphate battery, and thus the battery pack 100 can be manufactured without the heat dissipation structure, and the weight of the battery pack 100 can be minimized.
본 실시예의 리튬이온 배터리는 전압이 18V, 용량이 30A(암페어)이며, 기존 전동공구에 내장되는 충전용 배터리가 18V, 3~5A(2시간 사용)인 것에 비해 약 6~10배 이상의 전기가 저장되어 한 번 충전으로 10시간 이상 사용 가능하다.The lithium ion battery of this embodiment has a voltage of 18 V and a capacity of 30 A (amperes), and a rechargeable battery built in a conventional power tool has about 6 to 10 times more electricity than that of 18 V, 3 to 5 A It is stored and can be used for more than 10 hours with one charge.
전동공구와 같은 휴대용 전자 기기(1)에 전원을 공급하기 위한 보조 배터리로 사용하는 충전지는 한 번 충전하여 10시간 이상 사용하는 것이 더 효율적이므로, 급속 충전되는 리튬인산철 배터리를 사용할 필요가 없고 리튬이온(Li-ion) 배터리를 사용하는 것이 바람직하다.It is more efficient to use the rechargeable battery used as the auxiliary battery for supplying the power to the portable electronic device 1 such as the power tool for more than 10 hours by charging once and there is no need to use the lithium rechargeable lithium battery, It is preferable to use a Li-ion battery.
상기한 배터리 팩(100)은 작업자의 허리에 고정한 상태로 연결 케이블(200) 및 접속커버(300)로 휴대용 전자 기기(1)에 연결하여 사용할 수 있다. 배터리 팩(100)은 배터리 팩(100)을 장착할 수 있도록 제작한 허리벨트를 사용하여 작업자의 허리에 고정할 수 있다.The battery pack 100 may be connected to the portable electronic device 1 by the connection cable 200 and the connection cover 300 while being fixed to the waist of the operator. The battery pack 100 can be fixed to the waist of a worker using a waist belt designed to mount the battery pack 100.
연결 케이블(200)은 배터리 팩(100)과 접속커버(300)를 전기적으로 연결하기 위한 것이다. The connection cable 200 is for electrically connecting the battery pack 100 and the connection cover 300.
접속커버(300)는 휴대용 전자 기기(1)에 기존 배터리 장착부(3)(도 1 참조)를 대체하여 결합되고 일측에 연결 케이블(200)이 연결되어 충전지의 전원을 휴대용 전자 기기(1)에 공급할 수 있다.The connection cover 300 is connected to the portable electronic device 1 in place of the existing battery mounting part 3 (see FIG. 1) and is connected to one side of the connection cable 200 to supply the power of the rechargeable battery to the portable electronic device 1 Can supply.
배터리 팩, 연결 케이블, 접속커버가 연결되는 구성은 아래의 도 3에서 더 자세히 설명하기로 한다.The configuration in which the battery pack, the connection cable, and the connection cover are connected will be described in detail with reference to FIG. 3 below.
도 3에는 본 발명의 실시예에 의한 휴대용 전원 공급 장치를 전동공구에 연결하기 전 모습을 보인 분해 사시도가 도시되어 있다.FIG. 3 is an exploded perspective view showing a portable power supply device according to an embodiment of the present invention before connection to a power tool.
도 3에 도시된 바와 같이, 배터리 팩(100), 연결 케이블(200), 접속커버(300)는 조립에 의해 상호 연결될 수 있다. 배터리 팩(100), 연결 케이블(200), 접속커버(300)가 조립에 의해 상호 연결되게 구성하면 휴대용 전자 기기의 형상에 따라 다양한 규격으로 제작하고 작업시 필요한 규격으로 상호 연결하여 사용할 수 있다.As shown in FIG. 3, the battery pack 100, the connection cable 200, and the connection cover 300 may be interconnected by assembling. When the battery pack 100, the connection cable 200 and the connection cover 300 are configured to be interconnected by assembling, various standards can be manufactured according to the shape of the portable electronic device, and they can be connected to each other in a standard required for the operation.
배터리 팩(100)은 상부 측에 충전지로 전원을 공급하여 충전지를 충전시킬 수 있는 충전용 접속단자(110)를 구비한다. 충전용 접속단자(110)는 1핀 단자로 될 수 있다. 충전용 접속단자(110)에는 충전지의 충전을 위한 전원 케이블이 연결될 수 있다.The battery pack 100 is provided with a charging connection terminal 110 through which a rechargeable battery can be charged by supplying power from the rechargeable battery to the upper side. The charging connection terminal 110 may be a 1-pin terminal. A power cable for charging the rechargeable battery can be connected to the charging connection terminal 110.
