Description

차량용 배터리 팩의 결합구조{COMBINATION STRUCTURE OF INSTALLATION BATTERY PACK OF VEHICLE}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a battery pack,

본 발명은 차량용 배터리 팩의 결합구조에 관한 것으로, 더욱 상세하게는 전기차 또는 하이브리드 차량에 장착되는 차량용 배터리 팩의 결합구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a coupling structure of a battery pack for a vehicle, and more particularly to a coupling structure of a battery pack for a vehicle mounted on an electric vehicle or a hybrid vehicle.

전기차 또는 하이브리드 차량의 동력원으로 사용되는 이차전지(secondary cell)는 고출력 대용량이 요구되기 때문에 다수의 소형 이차전지(battery cell)들을 직렬 또는 병렬로 연결하여 배터리 셀 모듈을 형성하고, 배터리 셀 모듈 복수개를 병렬 또는 직렬로 연결하여 하나의 배터리 팩을 형성하여 사용하는 것이 일반적이다.2. Description of the Related Art [0002] A secondary battery used as a power source of an electric vehicle or a hybrid vehicle is required to have a high output capacity, so that a plurality of small secondary batteries are connected in series or in parallel to form a battery cell module, It is common to connect them in parallel or in series to form one battery pack.

이러한 배터리 팩은 차량 내부 및/또는 차량 외부에 장착될 수 있는데, 그 중 차량 외부에 장착되는 배터리 팩의 경우에는 장착 위치의 특성상 수밀 구조를 구비해야만 한다. 수밀 구조를 구비하지 않을 경우에는 배터리 팩의 내부에 수분이 유입되어 내부 회로들이 단락될 가능성이 있기 때문이다.The battery pack may be mounted inside the vehicle and / or outside the vehicle. In the case of the battery pack mounted outside the vehicle, the battery pack must have a watertight structure in view of characteristics of the mounting position. If the watertight structure is not provided, moisture may flow into the inside of the battery pack and the internal circuits may be short-circuited.

도 1은 종래 외부 배터리 팩의 결합구조(10)를 개략적으로 도시한 도면이다.1 is a view schematically showing a coupling structure 10 of a conventional external battery pack.

도 1을 참조하면, 종래 외부 배터리팩의 결합구조는 하부케이스(1) 상부에 EPDM(ethylene propylene dienemonomer) 가스켓(2)이 결합하고, 그 위에 순차적으로 상부케이스(3)가 결합한다. Referring to FIG. 1, in the conventional external battery pack coupling structure, an EPDM (ethylene propylene dienemonomer) gasket 2 is coupled to an upper portion of a lower case 1, and an upper case 3 is sequentially coupled thereto.

이때, 상기 구성들의 결합은 통상적으로 볼팅 공정을 통해 이루어지는 것이 일반적이다. 예컨대, 수십 개의 볼트 및 너트와 부싱을 이용하여 상기 구성들의 테두리를 볼팅 공정을 통해 결합하게 된다.At this time, the combination of the above structures is generally performed through a bolting process. For example, several dozen bolts and nuts and bushings may be used to join the edges of the configurations through a bolting process.

그런데, 이와 같이 볼팅 공정을 통해 외부 배터리팩을 결합시키는 경우에 도 2에 도시된 단면도와 바와 같이, 가스켓(2)의 길이 방향을 따라 형성된 볼팅 결합공(2a)에 부싱(4)이 체결된 상태에서 하부케이스(1)의 하부결합공(1a)과 상부케이스(3)의 상부결합공(3a)의 사이에 놓고 볼트를 체결하게 된다.2, when the external battery pack is coupled through the bolting process, the bushing 4 is fastened to the bolting hole 2a formed along the longitudinal direction of the gasket 2, as shown in the cross- The bolts are fastened between the lower engaging holes 1a of the lower case 1 and the upper engaging holes 3a of the upper case 3. [

이때, 고정이 안된 가스켓(2)은 상/하부결합공(3a)(1a)가 위치가 일치하지 않아서 볼트의 조립성이 저하되는 문제점이 있었다.At this time, the unfixed gasket 2 has a problem in that the assembling property of the bolt is deteriorated because the upper and lower engagement holes 3a and 1a are not aligned with each other.

더욱이 부싱(4)이 이동된 상태에서 결합이 이루어지면, 이탈 및 실링이 저하되는 문제점이 있었다.Further, when the bushing 4 is engaged in a state in which the bushing 4 is moved, there is a problem in that the separation and sealing are lowered.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

본 발명 명세서 전체에서, 어떤 부분이 어떤 구성요소를 "포함" 한다고 할 때, 이는 특별히 반대되는 기재가 없는 한 다른 구성요소를 제외하는 것이 아니라 다른 구성 요소를 더 포함할 수 있는 것을 의미한다.Throughout the specification of the present invention, when a part is referred to as "including " an element, it is understood that it may include other elements as well, without excluding other elements unless specifically stated otherwise.

여기서 도 3은 본 발명의 일실시예에 따른 차량용 배터리 팩의 결합구조를 보여주는 단면도이다.3 is a cross-sectional view illustrating a coupling structure of a battery pack for a vehicle according to an embodiment of the present invention.

본 발명의 차량용 배터리 팩은, 전기차나 하이브리드 차량의 내부에 장착되는 배터리 팩 뿐만 아니라, 차량의 언더바디(underbody) 아래에 장착되어 차량 외부에 노출되어 있는 배터리 팩도 포함할 수 있다.The vehicle battery pack of the present invention may include not only a battery pack mounted in an electric vehicle or a hybrid vehicle but also a battery pack mounted under the underbody of the vehicle and exposed to the outside of the vehicle.

그리고 본 발명에 있어서 배터리 팩의 결합구조를 제외한 배터리 팩의 각종 구성들(예컨대 차량 마운팅부, 냉각유로 인렛/아웃렛, 세이프티 플러그 등)은 통상적으로 사용되는 배터리 팩과 동일 또는 유사하므로 구체적인 설명은 생략하도록 한다.In the present invention, various configurations of the battery pack (for example, a vehicle mounting portion, a cooling channel inlet / outlet, a safety plug, etc.) other than the battery pack coupling structure are the same as or similar to those of a commonly used battery pack, .

도 3에 도시된 바와 같이 본 발명에 따른 차량용 배터리 팩의 결합구조는 크게, 하부케이스(100)와 상부케이스(110) 그리고 이들 상/하부케이스(110)(100)의 사이에 가스켓(120)이 설치되어 기밀성이 유지되도록 하는 구성을 가지고 있다.3, the structure of a battery pack for a vehicle according to an embodiment of the present invention includes a gasket 120 between a lower case 100 and an upper case 110, and upper and lower cases 110 and 100, So that airtightness can be maintained.

먼저, 하부케이스(100)는 상부케이스(110)와 결합하여 배터리 팩을 형성하는 것으로서, 테두리를 따라 하부플랜지(102)가 일체로 형성되어 결합 부위가 된다.First, the lower case 100 is coupled with the upper case 110 to form a battery pack, and the lower flange 102 is integrally formed along the rim to form a coupling part.

하부플랜지(102)는 형태, 형상, 크기 등은 한정하지는 않는다.The shape, shape, size, etc. of the lower flange 102 are not limited.

이 하부플랜지(102)상에는 길이 방향을 따라 하부결합공(104)이 일정 간격 이격되어 다수개가 형성될 수 있다.On the lower flange 102, a plurality of lower coupling holes 104 may be formed at predetermined intervals along the longitudinal direction.

그리고 상부케이스(110)는 하부케이스(100)의 상면에 안착되는 것으로, 하부플랜지(102)와 동일 형상으로 테두리를 따라 상부플랜지(112)가 형성될 수 있다.The upper case 110 is seated on the upper surface of the lower case 100 and the upper flange 112 may be formed along the rim in the same shape as the lower flange 102.

역시 상부플랜지(112)에도 하부결합공(104)과 대응되는 위치에 상부결합공(114)이 형성될 수 있다.The upper flange 112 may also have an upper coupling hole 114 at a position corresponding to the lower coupling hole 104.

한편, 하부케이스(100)와 상부케이스(110)의 사이에 누설을 방지하는 목적으로 하는 가스켓(120)이 설치될 수 있다.Meanwhile, a gasket 120 may be installed between the lower case 100 and the upper case 110 to prevent leakage.

가스켓(120)은 상/하부플랜지(112)(102)와 동일 형상으로 종류는 특정하지 않으며, 통상적으로 사용되는 재질이면 가능하다. 예컨데, 실리콘계, 변성 실리콘계, 폴리우레탄계, 폴리 설파이드계, 수성 아크릴계 등 일 수 있다.The gasket 120 has the same shape as that of the upper / lower flanges 112 and 102 and is not specific to the type, and can be used if it is a commonly used material. For example, it may be a silicone system, a modified silicone system, a polyurethane system, a polysulfide system, an aqueous acrylic system, or the like.

그리고 가스켓(120)에도 상/하부결합공(114)(104)과 대응되는 위치에 볼트결합공(122)이 형성될 수 있으며, 이 볼트결합공(122)에는 본 발명의 특징인 중공의 부싱(130)가 설치될 수 있다.A bolt coupling hole 122 may be formed in the gasket 120 at a position corresponding to the upper and lower coupling holes 114 and 104. The bolt coupling hole 122 may have a hollow bushing (130) may be installed.

부싱(130)의 몸체 하방으로 삽입돌기(132)가 일체로 연장 형성되며, 그 외경은 하부결합공(104)에 삽입이 가능함과 동시에 볼트(B)의 삽입이 가능한 내경을 갖는 것이 바람직하다.It is preferable that the insertion protrusion 132 integrally extends to the lower part of the body of the bushing 130 and the outer diameter thereof is capable of being inserted into the lower coupling hole 104 and having an inner diameter capable of insertion of the bolt B.

더욱이 삽입돌기(132)의 외주연으로는 이탈방지돌기(134)가 적어도 하나 이상 형성되어 상방으로의 이탈을 방지하게 된다.In addition, at least one of the detachment protrusions 134 is formed at the outer circumference of the insertion protrusion 132 to prevent the upward displacement.

이상과 같은 구성의 본 발명에 따른 차량용 배터리 팩의 결합구조의 작용을 다시 도 3을 참고하여 설명하면, 하부케이스(100)와 상부케이스(110)의 결합을 위하여 먼저, 하부케이스(100)의 하부플랜지(102) 상면으로 가스켓(120)을 위치시키게 된다.3, in order to engage the lower case 100 and the upper case 110, the upper case 110 and the lower case 100 are coupled to each other. And the gasket 120 is positioned on the upper surface of the lower flange 102.

이때, 하부플랜지(102)의 하부결합공(104)에 가스켓(120)의 부싱(130)를 위치시키되, 부싱(130)의 삽입돌기(132)가 하부결합공(104)에 관통 위치됨과 동시에 이탈방지돌기(134)에 의하여 이탈이 방지될 수 있다.At this time, the bushing 130 of the gasket 120 is positioned on the lower fitting hole 104 of the lower flange 102, and the insertion protrusion 132 of the bushing 130 is positioned through the lower fitting hole 104 The separation preventing protrusion 134 can prevent the separation.
