Abstract
Description
본 발명은 배터리 팩을 이루는 고정 구조물을 일체형으로 함으로서, 하드웨어의 수량을 최소화하여 양산 시간을 단축하고, 하드웨어에 의한 단점을 보완하기 위한 것이다.The present invention is to integrate the fixed structure constituting the battery pack, to minimize the quantity of hardware to shorten the mass production time, to compensate for the shortcomings caused by hardware.
친환경 HEV/PHEV/EV 차량의 배터리는 강건한 구조물을 통해 차체에 고정되어야 한다. 배터리 팩이 차량에서 진동/충격에 의해 발생된 유격 및 내부 균열은 배터리 팩의 안전성을 위협하는 존재가 된다. 따라서 배터리 팩을 차체에 고정하기 위해서 사용되는 멤버류(샤시류)의 소재는 대체로 고장력 강판이 사용된다. The battery of an eco-friendly HEV / PHEV / EV vehicle must be secured to the body via a robust structure. Gaps and internal cracks caused by vibrations / shocks in the vehicle are a threat to the safety of the battery pack. Therefore, a high tensile steel sheet is generally used for the members (chassis) used to fix the battery pack to the vehicle body.
대부분의 양산 및 개발 차량에서 필요에 따라 1~7개로 분할된 멤버를 사용하여 배터리 팩 제작에 사용됨에 따라, 분할된 멤버는 여러 구조물이 조립된 형상이어야한다. 즉, 기본적으로 여러 구조물이 복합된 멤버 부품을 다시 추가 공정을 통해 하나로 조립하여 사용함에 따라 공정의 수 및 구조물의 수가 많다. 현재 배터리 팩 제작 공정에서 하드웨어 조립은 매우 중요한 과정이다. 하드웨어는 각 부품들을 고정하고 유지하는데 필요한 부품이다. 하드웨어 체결 시 길이에 따라 약 3초의 시간이 소요된다. 이는 체결 수량이 많은 구조에서 양산 시간이 그 만큼 증가하게 됨을 의미한다.As most production and development vehicles use 1-7 members as needed to build a battery pack, the divided members must be assembled into several structures. In other words, as a result of assembling the member parts in which several structures are combined into one again through an additional process, the number of processes and the number of structures are large. Hardware assembly is a very important process in the current battery pack manufacturing process. Hardware is the part needed to hold and hold each part. When fastening the hardware, it takes about 3 seconds depending on the length. This means that the mass production time is increased by that much in the structure of fastening quantity.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 배터리 팩을 이루는 고정 구조물을 일체형으로 함으로서, 하드웨어의 수량을 최소화하여 양산 시간을 단축하고, 하드웨어에 의한 단점을 보완하기 위한 것이다.The present invention has been made to solve the above problems, by integrating a fixed structure constituting the battery pack, to minimize the quantity of hardware to shorten the mass production time, to compensate for the shortcomings caused by hardware.
상기 과제를 해결하기 위하여 본 발명은 메인멤버, 메인멤버에 수직방향으로 배치된 크로스멤버, 메인멤버는 서로 평행하게 배열된 제1메인멤버 및 제2메인멤버, 크로스멤버는 서로 평행하게 배열된 중앙크로스멤버, 좌측크로스멤버, 우측크로스 멤버, 제1메인멤버, 중앙크로스멤버, 좌측크로스멤버, 우측크로스 멤버, 제2메인멤버는 서로 일정간격 이격되도록 배치된 채, 6개의 점용접에 의해 일체형이 되며, 6개의 점용접은 제1메인멤버 및 제2메인멤버의 동일한 일측방향의 지점과 중앙크로스멤버, 좌측크로스멤버, 우측크로스 멤버의 길이방향의 중심선이 만나는 곳에 형성되는 것을 특징이 있다. In order to solve the above problems, the present invention includes a main member, a cross member disposed in a vertical direction in the main member, a main member having a first main member and a second main member arranged in parallel with each other, and a cross member having a center arranged in parallel with each other. The cross member, the left cross member, the right cross member, the first main member, the central cross member, the left cross member, the right cross member, and the second main member are arranged to be spaced apart from each other at a predetermined interval and are integrally formed by six spot welding. The six spot welding is formed where the same one-way point of the first main member and the second main member and the center line in the longitudinal direction of the center cross member, the left cross member, and the right cross member meet.
상기와 같이 이루어지는 본 발명은 배터리 팩의 구성에서 하위 레벨의 부품들을 하드웨어(공구)로 체결한 뒤에, 고정 구조물을 형성하며 하드웨어를 대신하여 점용접을 적용하는 것이다. 점용접을 위해서는 점용접 장비가 진입할 수 있는 경로가 확보되어야 한다. 그럼에도 그 외 하드웨어 체결에 비해 필요공간이 작은 장점이 있으며, 사용되는 개수도 대폭 축소된다. 공정상으로도 입고되는 다수의 하이 부품들이 1개로 축소되므로 재고관리도 용이하다.The present invention made as described above is to fasten the components of the lower level in the configuration of the battery pack with the hardware (tool), to form a fixed structure and apply spot welding in place of the hardware. Spot welding requires a path for spot welding equipment to enter. Nevertheless, there is an advantage that the required space is smaller than the hardware fastening, and the number used is greatly reduced. It is also easy to manage inventory because many high parts received in process are reduced to one.

Embodiment of the present invention may be modified in various forms, the scope of the invention should not be construed as limited to the embodiments described in detail below. This embodiment is provided to more completely explain the present invention to those skilled in the art.

도 1은 메인멤버와 크로스멥버가 용접 결합된 배터리 구조이다. 상기 배터리 고정구조는 메인멤버와 메인멤버에 수직방향으로 배치된 크로스멤버, 메인멤버의 일측단부와 크로스멤버가 점용접에 의해 일체형이 된다.1 is a battery structure in which the main member and the cross chamber are welded to each other. In the battery fixing structure, the main member and the cross member disposed in the vertical direction in the main member, one end of the main member and the cross member are integrated by spot welding.
접용접(spot welding)이란, 저항 발열을 이용하여 금속을 접합하는 저항용접법의 일종이다. 일반적으로 금속은 전기를 잘 전달하므로, 줄(JOULE) 발열을 이용한 방법으로 용접될 피금속판을 겹쳐서 전극으로 가압하여 전압을 인가하여 전류를 흐르게하면, 용접부가 줄 열에 의해 가열되어 용융되고 피용접재를 야금적으로 접합하게 된다. 장점으로 대부분 자동으로 진행되어 작업자의 숙련도에 영향이 적으며, 단시간에 용접을 진행하기 때문에 가열영역이 용접부 근방으로 한정되어 열에 의한 비틀림이 적고, 비교적 깨끗한 용접면 및 흄의 발생이 적다는 특징이 있다.Spot welding is a kind of resistance welding method in which a metal is joined using resistance heat generation. In general, the metal transfers electricity well. Therefore, when the metal plate to be welded is pressurized with an electrode to apply a voltage to flow an electric current, the weld is heated and melted by the heat of the joule and welded material. Metallurgical bonding. Advantageously, it is mostly automatic and has little influence on the skill of the operator, and because welding is performed in a short time, the heating area is limited to the vicinity of the welding part, so that there is little torsion by heat, and relatively clean welding surface and the generation of fume are less have.

차량고정부는 지면으로부터 베이스보다 높은 곳에 위치한다. 즉, 차량고정부와 베이스부는 단차를 형성하며, 이러한 단차는 연결부에 의해 형성되어진다. 연결부는 S자형이나 만곡부를 갖는 형태로서 제1메인멤버 및 제2메인멤버를 하부에서 지지하는 베이스부를 차량고정부와 연결시킨다.The vehicle fixing part is located above the base from the ground. That is, the vehicle fixing part and the base part form a step, and this step is formed by the connecting part. The connecting portion has an S-shape or a curved portion to connect the base portion supporting the first main member and the second main member to the vehicle fixing part.
각각 베이스부(60), 연결부(80), 차량고정부(70)를 포함하는 중앙크로스멤버(30), 좌측크로스멤버(40), 우측크로스멤버(50)는 제1메인멤버(10) 및 제2메인멤버(20)와 접용접에 의해 고정된다. The
