내연기관 자동차는 가솔린 또는 경유 등의 연료를 사용하여 이를 혼합공기와 동시에 엔진의 내부에 흡입하여 이를 연소시킴으로서 구동력을 발생시켜 자동차의 주행이 이루어지도록 하는 것이다.An internal combustion engine vehicle uses fuel such as gasoline or diesel to suck it into the mixed air at the same time as the mixed air and burns it to generate driving force so that the driving of the vehicle is performed.
그리고 태양광 자동차는 태양광 에너지를 흡수하여 이를 전기적 에너지로 변환시켜 모터를 구동시킴으로서 자동차의 주행이 이루어지게 되는 것이다.And a solar car absorbs solar energy and converts it into electrical energy to drive a motor, thereby driving the car.
또한 전기 자동차는 배터리 등의 전기 에너지를 이용하여 전동기를 회전시켜 바퀴를 구동시킴으로서 자동차의 주행이 이루어지도록 하는 것이다.In addition, the electric vehicle is to drive the wheel by driving the wheel by rotating the electric motor using the electric energy, such as a battery.
상기한 전기자동차는 동력원으로 사용되는 배터리 어셈블리가 자동차의 저면에 배치되고, 상기한 배터리 어셈블리에 의하여 구동되는 구동모터가 차량의 프론트 측에 배치된다.In the electric vehicle, a battery assembly, which is used as a power source, is disposed on the bottom of the vehicle, and a driving motor driven by the battery assembly is disposed on the front side of the vehicle.
도 1은 배터리 어셈블리를 이루는 배터리를 도시한 측면도로서, 배터리(101)를 도시하고 있다.1 is a side view illustrating a battery constituting a battery assembly, and illustrates a battery 101.
도 4는 도 1의 A-A부를 도시한 단면도로서, 외관을 이루며 그 내부에 수납공간이 형성되는 몸체(103)와, 상기한 몸체(103)의 상단부에 결합되는 리드(105)를 도시하고 있다.FIG. 4 is a cross-sectional view of the A-A part of FIG. 1, which illustrates a body 103 having an appearance and a receiving space formed therein, and a lid 105 coupled to an upper end of the body 103.
상기한 리드(105)와 몸체(103) 사이에는 실링부재(107)가 배치되어 배터리 내부에서 발생하는 수소가스가 외부로 배출되는 것을 억제하도록 리드(105)와 밀착되는 구조로 이루어지고 있다.The sealing member 107 is disposed between the lid 105 and the body 103 to have a structure in close contact with the lid 105 to suppress the discharge of hydrogen gas generated inside the battery to the outside.
상기한 몸체(103)의 내부에는 양극과 음각을 이루는 극판(109)이 교대로 배치되며 그 내부가 묽은 황산의 전해액으로 채워지는 구조로 이루어지고 있다.The inside of the body 103 has a structure in which the pole plate 109 forming an intaglio and an intaglio are alternately arranged, and the inside thereof is filled with a dilute sulfuric acid electrolyte.
도 5는 도 4의 주요부를 도시한 도면으로서, 리드(105)를 도시하고 있다.FIG. 5 shows the main part of FIG. 4 and shows the lid 105.
상기한 리드(105)는 중앙부 및 양측에 통공(111)(113)이 형성되는 구조로 이루어지며, 통공(111)(113)이 형성되는 부위와 외측면이 단차 또는 만곡의 형태를 이루며 돌출되는 구조로 이루어지고 있다.The lead 105 has a structure in which the through holes 111 and 113 are formed at the center and both sides, and the portions and the outer surfaces of the through holes 111 and 113 are formed to protrude in the form of steps or curves. It is made of structure.
한편 상기한 리드(105)의 중앙부에 형성되는 통공(111)은 배터리의 내부에 일정압 이상의 수소가스가 발생하게 되면 별도로 형성되는 가스 배출 장치를 배치하기 위한 것이다.On the other hand, the through hole 111 formed in the center of the lead 105 is for disposing a gas discharge device that is formed separately when the hydrogen gas of a predetermined pressure or more generated inside the battery.
그리고 리드(105)의 양측면에 형성되어 있는 통공(113)은 음극 단자와 양극 단자가 각각 돌출될 수 있도록 형성되는 것이다.In addition, the through holes 113 formed on both side surfaces of the lead 105 are formed to protrude from the negative terminal and the positive terminal, respectively.
상기한 종래의 전기자동차용 배터리는, 리드의 양측단에 형성되어 있는 통공을 통하여 단자가 외측으로 돌출되도록 설계가 이루어지고 이 통공으로 몸체 내부에서 발생한 수소가스가 배출되지 않도록 실링부재에 의하여 밀폐되는 구조를 이루고 있으나, 굴곡이 이루어지는 형태로 리드가 제작됨으로서 실링부재와 접촉하는 면의 평평도가 일정하게 유지되지 않게 되어 수소가스가 배출되어 배터리의 성능을 감소시킴으로서 신뢰성을 떨어뜨리는 단점이 있게 된다.The conventional battery for an electric vehicle is designed such that the terminal protrudes outward through the through holes formed at both ends of the lead and is sealed by the sealing member so that hydrogen gas generated inside the body is not discharged through the through holes. However, since the lead is manufactured in the form of bending, the flatness of the surface contacting the sealing member is not kept constant so that hydrogen gas is discharged to reduce the performance of the battery, thereby reducing the reliability.
그리고 리드의 굴곡이 깊게 형성되어 프레스시 압력이 증대되어 에너지 소비 증대되는 등의 제작비용이 상승되며, 리드의 중량이 증대되는 문제점이 있게 된다.In addition, the bending of the lead is deeply formed, so that the pressure during the press increases production cost, such as increased energy consumption, and the weight of the lead increases.
따라서 상기한 본 발명에 따른 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 실링부재와 접촉되는 리드의 평평도를 증대시켜 기밀을 증대시킴으로서 수소방출을 억제하여 신뢰도를 증대시키고 제작비용을 감소시킴은 물론 중량을 감소시키는 전기자동차용 배터리를 제공하는 데 있다.Therefore, to solve the problems according to the present invention as described above, the object of the present invention is to increase the flatness of the lead in contact with the sealing member to increase the airtight to suppress hydrogen emissions to increase the reliability and reduce the manufacturing cost Sikkim, of course, to provide an electric vehicle battery for reducing the weight.
상기한 본 발명의 목적을 달성하기 위하여, 내부에 수납공을 이루며 외관을 형성하는 몸체와, 상기한 몸체의 상단부에 고정 결합되는 리드와, 상기한 리드와 몸체의 기밀을 유지하기 위한 실링부재를 포함하는 전기자동차용 배터리에 있어서, 상기한 리드는 음극 단자, 양극 단자, 그리고 수소배출장치를 배치하기 위한 통공이 동일 평면상에 형성됨을 특징으로 하는 전기자동차용 배터리를 제공한다.In order to achieve the object of the present invention, a body forming a receiving hole therein and forming an appearance, a lead fixed to the upper end of the body, and the sealing member for maintaining the airtight of the lead and the body In the battery for an electric vehicle comprising, the lead provides a battery for an electric vehicle, characterized in that the through-holes for arranging the negative terminal, the positive terminal, and the hydrogen discharge device are formed on the same plane.

이하, 본 발명에 따른 바람직한 실시예를 첨부한 도면을 참조하여 보다 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 일반적인 배터리를 도시한 측면도로서, 기호 101은 배터리를 나타내고 있다.1 is a side view illustrating a general battery, and the symbol 101 represents a battery.
도 2는 도 1의 A-A부를 절개하여 본 발명의 실시예를 도시한 단면도로서, 외관을 이루며 내부에 수납공간이 형성되는 몸체(1)와, 상기한 몸체(1)의 상단에 배치되는 리드(3), 그리고 상기한 몸체(1)와 리드(3) 사이에 기밀을 유지하기 위한 실링부재(5)가 개재되는 구조로 이루어지고 있다.FIG. 2 is a cross-sectional view illustrating an embodiment of the present invention by cutting the AA part of FIG. 1. The body 1 forms an appearance and a storage space is formed therein, and a lead disposed on an upper end of the body 1. 3) and the sealing member 5 for keeping the airtightness between the body 1 and the lid 3 is formed.
상기한 몸체(1)의 내측부에는 양극 및 음극판이 교대로 배치되는 극판(7)이 설치되는 구조로 이루어지며 그 내부에는 묽은 황산으로 이루어지는 전해액이 채워지고 있다.The inner portion of the body 1 is made of a structure in which the positive electrode plate 7 is arranged alternately disposed between the positive electrode and the negative electrode plate is filled with an electrolyte solution made of dilute sulfuric acid.
그리고 상기한 실링부재(5)는 몸체내에서 발생하는 수소가스가 리드(3)의 일측에 형성되어 있는 통공(도시생략)을 통하여 외부로 방출되는 것을 막기 위하여 리드(3)와 밀착되는 구조로 이루어지고 있다.The sealing member 5 has a structure in close contact with the lid 3 to prevent hydrogen gas generated in the body from being discharged to the outside through a through hole (not shown) formed at one side of the lid 3. It is done.
상기한 리드(3)는, 도 3에 도시하고 있는 바와 같이, 양측단에 양, 음극단자가 끼워질 수 있는 통공(9)이 형성되며 중앙부에 일정한 압력이상이 되면 자동적으로 수소가스를 배출하는 수소가스 배출장치가 배치되는 통공(11)이 형성되는 구조로 이루어지고 있다.As shown in FIG. 3, the lead 3 has a through hole 9 into which both positive and negative terminals can be inserted at both ends, and automatically discharges hydrogen gas when the pressure is higher than a predetermined pressure in the center. It is made of a structure in which a through-hole 11 in which the hydrogen gas discharge device is disposed is formed.
상기한 통공(9)(11)은 리드(3)의 동일 평면상에 배치되고 있다.The through holes 9 and 11 are arranged on the same plane of the lid 3.
즉 리드(3)는 실링부재(5)와 접촉하는 면이 굴곡을 이루지 않고 평평한 구조로 이루어지게 되는 것이다.That is, the lead 3 is formed in a flat structure without the surface contacting the sealing member 5 is not curved.
따라서 리드(3)를 제작하기 위하여 프레스할 때에 단지 통공(9)(11)만을 형성하면 됨으로서 제작 용이하게 된다. 따라서 고평평도를 유지할 수 있게 되는 것이다.Therefore, only the through holes 9 and 11 need to be formed at the time of pressing in order to manufacture the lead 3, thereby facilitating manufacture. Therefore, high flatness can be maintained.
이와 같이 이루어지는 전기자동차용 배터리는 리드(3)와 몸체(1)의 기밀을 견고하게 유지할 수 있게 된다.The battery for an electric vehicle made in this way can firmly maintain the airtight of the lid 3 and the body 1.
상기한 본 발명에 따른 전기자동차용 배터리는, 리드의 고평평도를 유지하여 몸체의 내부에서 발생하는 수소가스의 배출을 억제하고 리드를 용이하게 제작 할 수 있어 제작 비용이 절감됨은 물론, 불필요한 부분의 삭제로 중량을 감소시킬 수 있게 된다.The battery for an electric vehicle according to the present invention can maintain the high flatness of the lead to suppress the discharge of hydrogen gas generated inside the body and can easily manufacture the lead, thereby reducing manufacturing costs, as well as unnecessary parts It is possible to reduce the weight by eliminating.
