본 발명은 누액방지용 기능성 고어텍스 섬유를 적용한 오프로드 차량 납축전지 상카바에 관한 것으로서, 더욱 상세하게는 상카바에 위치한 Flame Arrester(방폭필터)에 기능성 고어텍스층(100)을 적층함에 따라, 방수성과 투습성이라는 상반된 특성을 이용하여 오프로드 차량에 진동 발생시 납축전지 내부의 전해액이 외부로 누출되지 않도록 하며, 기화된 황산 가스는 외부로 배출할 수 있게 되어 납축전지의 폭발을 방지할 수 있는 누액방지용 기능성 고어텍스 섬유를 적용한 오프로드 차량 납축전지 상카바에 관한 것이다.The present invention relates to an off-road vehicle lead acid battery top cover applied with a functional Gore-Tex fiber for preventing leakage, and more specifically, as the functional Gore-Tex layer (100) is laminated to a Flame Arrester (explosion-proof filter) located in the top cover, waterproof By using the opposite characteristics of super moisture permeability, it prevents the electrolyte inside the lead acid battery from leaking to the outside when vibration occurs in an off-road vehicle, and the vaporized sulfuric acid gas can be discharged to the outside to prevent leakage of the lead acid battery. It relates to an off-road vehicle lead acid battery Sangkaba applied with functional Gore-Tex fibers.

납축전지는 충전(charging)된 전기를 방전(discharge)에 의하여 공급하는 것이고 충전과 방전하는 과정을 허용된 횟수 동안 반복하므로 반복 재사용이 가능한 이차전지(secondary battery) 또는 축전지(이하, '납축전지'라 한다.)라고 한다.A lead acid battery supplies charged electricity by discharging and repeats the charging and discharging process for an allowed number of times, so that it can be reused repeatedly as a secondary battery or a storage battery (hereinafter, 'lead battery'). It says.)

납축전지는 양극과 음극 및 전해질(이하, '전해액'이라 한다.)로 사용되는 재료에 의하여 다양한 종류로 분류되고, 전극에 납을 사용하며 전해액으로는 황산을 사용하는 구성을 납축전지로 분류한다.Lead-acid batteries are classified into various types according to materials used as anodes, cathodes, and electrolytes (hereinafter referred to as 'electrolyte'), and lead-acid batteries are classified into lead-electrodes and sulfuric acid as electrolytes. .

납축전지의 전극은 크게 양극과 음극용의 극판, 극주로 구분되고 각 전극을 물리적 및 전기적으로 구분하는 격리판 및 전해액을 포함하여 케이스에 수납 또는 수용하므로 내장하며, 충전과 방전 과정에서 발생되는 수소가스와 전해액이 증발하여 발생하는 가스를 배출하기 위하여 밀폐된 케이스에 가스 배기구를 구비하는 것이 일반적이다.The electrodes of lead-acid batteries are largely divided into pole plates for anodes and cathodes, poles, and contain and store them in cases, including separators and electrolytes that physically and electrically separate each electrode, so they are built in. Hydrogen generated during charging and discharging It is common to provide a gas exhaust port in a closed case to discharge gas generated by evaporation of gas and electrolyte.

납축전지는 일례로, 화학반응식 PbO2 + H2SO4 ↔ PbSO4 + 2H2O의 가역반응을 통해 방전과 충전을 반복하는 원리로 동작하는 것으로, 생성된 전기는 방전하여 출력하고 입력된 전기는 충전하여 저장한다.Lead-acid batteries, for example, operate on the principle of repeating discharging and charging through the reversible reaction of chemical reactions PbO2 + H2SO4 ↔ PbSO4 + 2H2O. The generated electricity is discharged and output, and the input electricity is charged and stored.

납축전지는 이산화납(PbO2)으로 만든 극판과 황산액(H2SO4) 성분의 전해액이 황산화 납(PbSO4)과 물(H2O)로 변화하는 화학작용을 이용하는 것으로, 황산화 납(PbSO4)과 물(H2O)로 변화할 때 전기를 생성 및 방출하고, 충전이 되는 경우에는 반대로 치환하는 작용을 반복하게 된다.The lead acid battery uses a chemical reaction in which the electrode plate made of lead dioxide (PbO2) and the electrolyte solution of the sulfuric acid solution (H2SO4) are converted into lead sulfate (PbSO4) and water (H2O), and lead sulfate (PbSO4) and water ( When it changes to H2O), electricity is generated and released, and when charged, the action of reverse substitution is repeated.

이러한 화학 반응식이 진행될 때마다, 납축전지 내부에서는 열이 발생하여 일부의 전해액이 증발하는 동시에 미량의 수소가스가 발생되므로 폭발 등의 방지를 위하여 생성된 가스를 외부로 배출하여야 한다.Whenever such a chemical reaction is performed, heat is generated inside the lead acid battery, and a part of the electrolytic solution is evaporated while a small amount of hydrogen gas is generated, so the generated gas must be discharged to prevent explosions.

또한, 차량용 납축전지는 차량이 이동하면서 발생하는 진동과 기울어짐에 여과 없이 노출되고 이때 가스 배기구를 통하여 전해액이 외부로 누출되지 않도록 하여야 한다.In addition, the lead acid battery for vehicles is exposed to vibration and inclination generated while the vehicle is moving without filtration, and at this time, the electrolyte should not be leaked to the outside through the gas exhaust port.

종래 기술에 의한 것으로 납축전지 내부에서 발생한 가스를 외부로 배출하는 기술은 특허출원 제10-2000-72402호(2000 12 01)의 '자동차용 배터리의 증발가스 배출구조'와 특허출원 제10-2008-20115호(2008 05 29)의 '니켈-수소전지용 벤트 플러그' 등이 있다.According to the prior art, the technology for discharging the gas generated inside the lead acid battery to the outside is described in Patent Application No. 10-2000-72402 (2000 12 01), 'Evaporation Gas Emission Structure of Automotive Battery' and Patent Application No. 10-2008 -'Vent plug for nickel-hydrogen batteries' of 20115 (2008 05 29).

한편, 현재, 차량의 기능이 다양화되고 특화됨으로써, 납축전지도 특정 환경에 견뎌내기 위한 특수용 납축전지가 다양하게 개발되고 있다.Meanwhile, as the functions of vehicles are diversified and specialized, a variety of special lead-acid batteries for lead-acid batteries to withstand a specific environment have been developed.

이에 따라 Off Road에서의 진동으로 인한 전해액 누액방지로 발생되는 배터리 불량 발생, 차량 손상 및 쇼트, 본 네트 및 기타 주요 부품 부식 등을 개선할 필요가 있었다.Accordingly, it was necessary to improve the occurrence of battery defects, vehicle damage and shorts, corrosion of the bonnet and other major parts caused by electrolyte leakage prevention due to vibration on the off road.

따라서, 본 발명인 누액방지용 기능성 고어텍스 섬유를 적용한 오프로드 차량 납축전지 상카바를 제안하게 된 것이다.Therefore, the present invention proposes an off-road vehicle lead acid battery top cover to which a functional Gore-Tex fiber for preventing leakage is applied.

납축전지의 상부에 설치되는 메인카바(1)와, The main cover (1) installed on the top of the lead acid battery,

상기 메인카바(1)의 상측에 설치되는 상카바(2)로 구성되고, 상기 상카바(2)에 외부의 불꽃이 가스 배출 통로(6)를 통하여 납축전지의 내부로 유입되는 것을 차단하는 방폭필터(3)가 설치된 밀폐형 납축전지에 있어서, Explosion-proof consisting of a top cover (2) installed on the upper side of the main cover (1), to prevent the external flame to the inside of the lead acid battery through the gas discharge passage (6) to the top cover (2) In the sealed lead-acid battery provided with a filter (3),

이때, 상기 기능성 섬유인 고어텍스층(100)은,At this time, the functional fiber Gore-Tex layer 100,

이하, 본 발명에 의한 누액방지용 기능성 고어텍스 섬유를 적용한 오프로드 차량 납축전지 상카바의 실시예를 통해 상세히 설명하도록 한다.Hereinafter, an embodiment of the off-road vehicle lead acid battery top cover to which the functional Gore-Tex fiber for preventing leakage according to the present invention is applied will be described in detail.

납축전지의 벤트홀은 상측 커버에 위치하게 된다.The vent hole of the lead acid battery is located on the upper cover.

이때, 납축전지 내부에 보관된 전해액의 경우, 장시간 사용에 의하여 극판에 불활성 물질이 많아지는 경우 배터리의 성능이 크게 줄어들어 열이 발생한다. At this time, in the case of the electrolyte stored in the lead acid battery, when the inert material is increased in the electrode plate due to long-term use, the performance of the battery is greatly reduced and heat is generated.

이로 인하여 카바 측면에 존재하는 Vent Hole을 통하여 전해액 가스가 발생할 수 있는데 이는 전해액에 공존하는 H20 및 H2SO4가 열에 의해 반응함으로써, 가스가 외부로 유출될 수 있다. Due to this, an electrolyte gas may be generated through a Vent Hole located on the side of the cover. H20 and H2SO4 coexisting in the electrolyte react with heat, so that the gas may flow out.

심한 경우 외부로 유황 가스 냄새가 발생할 수도 있으며 이러한 황산가스가 발생할 때는 배터리에 특히 가스발생은 배터리 내부의 복배 현상까지 나타날 수 있고, 심한 경우 전해액의 누액도 발생할 수 있어 배터리에 대한 성능 및 안정성에 큰 영향을 줄 수 있다.In severe cases, the smell of sulfur gas may be generated to the outside, and when such sulfuric acid gas is generated, gas generation may occur even in the inside of the battery, and in severe cases, electrolyte leakage may also occur, which greatly affects the performance and stability of the battery. It can affect.

따라서, 본 발명에서는 상카바에 위치한 Flame Arrester(방폭필터)에 기능성 고어텍스층(100)을 적층함에 따라, 방수성과 투습성이라는 상반된 특성을 이용하여 오프로드 차량에 진동 발생시 납축전지 내부의 전해액이 외부로 누출되지 않도록 하며, 기화된 황산 가스는 외부로 배출할 수 있게 되어 납축전지의 폭발을 방지할 수 있도록 하였다.Therefore, in the present invention, as the functional Gore-Tex layer 100 is stacked on the Flame Arrester (explosion-proof filter) located in Sangkaba, the electrolyte inside the lead acid battery is external when vibration occurs in the off-road vehicle by using the opposite characteristics of waterproofness and moisture permeability. In order to prevent leakage, the vaporized sulfuric acid gas can be discharged to prevent the explosion of the lead acid battery.

도 1은 종래의 밀폐형 납축전지의 카바 구조를 나타낸 사시도이다.1 is a perspective view showing a cover structure of a conventional sealed lead acid battery.

도 2는 본 발명의 일실시예에 따라 누액방지용 기능성 고어텍스 섬유를 적용한 오프로드 차량 납축전지 상카바를 나타낸 평면도이다.2 is a plan view showing an off-road vehicle lead acid battery top cover to which a functional Gore-Tex fiber for preventing leakage is applied according to an embodiment of the present invention.

도 4는 본 발명의 일실시예에 따라 누액방지용 기능성 고어텍스 섬유를 적용한 오프로드 차량 납축전지 상카바의 단면도이다.4 is a cross-sectional view of an off-road vehicle lead acid battery top cover to which a functional Gore-Tex fiber for preventing leakage is applied according to an embodiment of the present invention.

도 1에 도시한 바와 같이, 납축전지의 상부에 메인카바(1)를 형성하고 있으며, 상기 메인카바(1)의 상측에 상카바(2)를 구성하고 있다.As shown in FIG. 1, the main cover 1 is formed on the top of the lead acid battery, and the top cover 2 is formed on the upper side of the main cover 1.

여기서, 상기 상카바(2)에 외부의 불꽃이 가스 배출 통로(6)를 통하여 납축전지의 내부로 유입되는 것을 차단하는 방폭필터(3)가 설치되게 된다.Here, an explosion-proof filter 3 is installed in the upper cover 2 to block external sparks from flowing into the lead acid battery through the gas discharge passage 6.

상기 방폭필터(3)를 본 발명에서는 Flame Arrester로 설명하고 있다.In the present invention, the explosion-proof filter 3 is described as Flame Arrester.

이때, 도 2 내지 도 3에 도시된 바와 같이, 납축전지 내부에서 발생된 가스는 방폭필터(3)와 기능성 섬유인 고어텍스층(100)을 거쳐 상카바(2)의 측면 가스 배출 통로(6)를 통과하여 외부로 배출되게 된다.At this time, as shown in FIGS. 2 to 3, the gas generated inside the lead acid battery passes through the explosion-proof filter 3 and the Gore-Tex layer 100, which is a functional fiber, and the side gas discharge passage 6 of the upper cover 2 ) To be discharged to the outside.

그리고, 메인카바의 일측에 단자(4)가 형성되어 있다.And, the terminal 4 is formed on one side of the main cover.

또한, 납축전지에는 화학반응이 완료된 수소 기체가 배출될 수 있도록 상카바(Final Cover)에 Vent hole이 있으며, Vent hole은 상카바에 폭발방지를 위한 Flame Arrest와 연결되어 있다. In addition, the lead acid battery has a vent hole in the final cover so that hydrogen gas that has undergone a chemical reaction can be discharged, and the vent hole is connected to the flame arrester to prevent explosion in the shank bar.

고진동 발생시 Flame Arrest의 전해액 젖음 현상이 발생하여 배터리 누액이 된다. When high vibration occurs, the electrolytic solution wetness of the Flame Arrest occurs, resulting in battery leakage.

본 발명은 상카바에 위치한 Flame Arrester에 기능성 고어텍스 섬유층을 적층하여 방수성과 투습성이라는 상반된 특성을 이용하여 누액방지용 기능성 섬유를 납축전지 상카바에 적용한 것이다.The present invention is to apply a functional fiber for preventing leaks to a lead acid battery upper cover by stacking a functional Gore-Tex fiber layer on a Flame Arrester located in the upper cover and using the opposite characteristics of waterproofness and moisture permeability.

상기 방폭필터(3)는 다공성 물질로 되어있으며, 축전지 내부의 가스는 외부로 배출시키고, 외부의 화염이 납축전지 내부로 유입되어 납축전지 폭발을 방지하는 기능이 있다. The explosion-proof filter (3) is made of a porous material, and the gas inside the battery is discharged to the outside, and an external flame is introduced into the lead-acid battery to prevent explosion of the lead-acid battery.

이때, 본 발명에서는 방폭필터(3)에 기능성 섬유인 고어텍스층(100)을 적층하여 황산증기는 투과되고 황산 전해액은 납축전지 내부로 재투입되도록 하게 되는 것이다.At this time, in the present invention, the Gore-Tex layer 100, which is a functional fiber, is stacked on the explosion-proof filter 3 so that sulfuric acid vapor is permeated and the sulfuric acid electrolyte is re-introduced into the lead acid battery.
