The present invention relates to a gas discharge structure of a nickel battery for an electric vehicle.
종래 전기자동차용 전지인 Ni-MH전지는 도 1에 도시한 바와 같이, 전지 뚜껑(1)의 상면에 벤트 캡(2)이 벤트 홀더(3)에 의해 복개되어 있다.In a conventional Ni-MH battery, which is a battery for an electric vehicle, a vent cap 2 is covered by a vent holder 3 on an upper surface of a battery lid 1 as shown in FIG. 1.
부호 4는 고무재질의 격벽(septum)이다.Reference numeral 4 is a septum of rubber material.
이와 같이 구성되어 있는 종래 가스 방출 구조는 전지 내부에 가스가 규정치 이상으로 발생되면 격벽(4)이 수축되면서 벤트 홀더(3)의 양측에 형성되어 있는 벤트 홀(3a)을 통해 가스가 방출되는 구조이다.The conventional gas discharge structure configured as described above has a structure in which the gas is discharged through the vent holes 3a formed at both sides of the vent holder 3 while the partition wall 4 is contracted when the gas is generated above the prescribed value. to be.
그러나 종래의 가스 방출 구조에서는 벤트 홀더(3)에 벤트 홀(3a)을 형성하는 공정이 간단치 않은 어려움이 있다.However, in the conventional gas discharging structure, the process of forming the vent hole 3a in the vent holder 3 is not easy.
이와 같은 문제점을 감안하여 안출한 본 고안의 목적은 보다 간소한 구조의 가스 방출 구조에 의해 제조단가를 절감하도록 한 전기자동차용 니켈 전지의 가스 방출 구조를 제공함에 있다.The object of the present invention devised in view of the above problems is to provide a gas discharge structure of the nickel battery for an electric vehicle to reduce the manufacturing cost by a gas discharge structure of a simpler structure.

상기 본 고안의 목적을 달성하기 위하여, 벤트 캡을 전지 뚜껑의 상면에 고정시키는 벤트 홀더의 내주면을 크게 형성하여 벤트 캡과의 사이에 소정의 공간부를 형성하여 구성함을 특징으로 하는 전기자동차용 니켈 전지의 가스 방출 구조가 제공된다.In order to achieve the object of the present invention, the inner circumferential surface of the vent holder for fixing the vent cap to the upper surface of the battery lid to form a large space between the vent cap and the nickel for electric vehicle, characterized in that the configuration The gas release structure of the cell is provided.
이하, 상기한 본 고안을 첨부 도면에 도시한 일 실시예에 의거하여 보다 상세히 설명한다.Hereinafter, the present invention will be described in more detail based on the embodiment shown in the accompanying drawings.
첨부 도면 도 2는 본 고안에 의한 전기자동차용 니켈 전지의 가스 방출 구조를 보인 단면도이고, 도 3은 도 2의 평면도로서, 이에 도시한 바와 같이, 본 고안은 벤트 캡(12)을 잡아주는 벤트 홀더(13)와 벤트 캡(12)의 결합 부분 사이에 공간부(13a)가 형성되도록 벤트 홀더(13)와 벤트 캡(12)을 결합한 것이다.2 is a cross-sectional view illustrating a gas discharge structure of the nickel battery for an electric vehicle according to the present invention, and FIG. 3 is a plan view of FIG. 2. As shown in the drawing, the present invention provides a vent for holding a vent cap 12. The vent holder 13 and the vent cap 12 are coupled to each other so that the space 13a is formed between the holder 13 and the coupling portion of the vent cap 12.
상기 벤트 홀더(13)와 벤트 캡(12) 사이의 이격된 만큼의 공간부(13a)가 가스가 방출되는 벤트 홀의 역할을 수행하도록 구성한 것이다.The space 13a spaced apart between the vent holder 13 and the vent cap 12 is configured to serve as a vent hole through which gas is discharged.
이와 같이 구성되는 본 고안에 의한 전기자동차용 니켈 전지의 가스 방출 구조에 의하면 전지의 내부의 규정치 이상의 가스가 방출되는 경우에 전지 뚜껑(11)측으로 발생되는 가스는 격벽(14)이 수축되면서 벤트 홀더(13)와 벤트 캡(12) 사이의 공간부(13a)로 방출된다.According to the gas discharge structure of the nickel battery for an electric vehicle according to the present invention configured as described above, the gas generated toward the battery lid 11 when the gas is discharged above the specified value inside the battery is vented as the partition wall 14 is contracted It is discharged to the space portion 13a between the 13 and the vent cap 12.
이상에서 설명한 바와 같이, 본 고안에 의한 전기자동차용 니켈 전지의 가스 방출 구조는 벤트 홀더에 별도의 벤트 홀을 형성하지 않고도 쉽게 가스가 전지의 외부로 방출되는 구조로서, 제조단가 및 생산성이 향상되는 효과가 있다.As described above, the gas discharge structure of the nickel battery for an electric vehicle according to the present invention is a structure in which gas is easily discharged to the outside of the battery without forming a separate vent hole in the vent holder, and manufacturing cost and productivity are improved. It works.
