도 2(가),(나)와 같이, 파이프너트(11)를 부시(12)에 뚫린 축홀(12a)로 끼워 파이프너트(11)의 체결단(11a)이 부시(12)로부터 빠져나온 상태로 만들어 준다.2 (a) and (b), the pipe nut 11 is inserted into the shaft hole 12a drilled through the bush 12 so that the fastening end 11a of the pipe nut 11 is pulled out of the bush 12. Make it.

이때, 상기 부시(12)는 파이프너트(11)의 외주면에 가류시켜 고정되어진다.At this time, the bush 12 is fixed to the outer peripheral surface of the pipe nut 11 is fixed.

이어 도 2(다)와 같이, 파이프너트(11)와 일체화된 부시(12)를 마운팅컵(13)에 집어 넣어준 후 강화브래킷(14)을 결합시켜준다.Subsequently, as shown in FIG. 2 (c), the bush 12 integrated with the pipe nut 11 is put into the mounting cup 13, and then the reinforcing bracket 14 is coupled.

이때, 상기 강화브래킷(14)은 축홀(14a)을 이용해 파이프너트(11)의 체결단(11a)에 끼워주게 된다.At this time, the reinforcing bracket 14 is fitted to the fastening end 11a of the pipe nut 11 using the shaft hole 14a.

또한, 상기 강화브래킷(14)의 축홀(14a)이 뚫린 면에 스폿(Spot)용접을 함으로써, 상기 강화브래킷(14)이 마운팅컵(13)의 확장플랜지(13a)에 고정되어진다.In addition, spot welding is performed on the surface of the reinforcing bracket 14 where the shaft hole 14a is drilled to fix the reinforcing bracket 14 to the expansion flange 13a of the mounting cup 13.

이어 도 2(라)와 같이 강화브래킷(14)의 축홀(14a)로 빠져나온 파이프너트(11)의 체결단(11a)에 체결너트(15)를 체결해줌으로써, 서로 조립된 각 부품들을 일체화시켜 준다.Then, as shown in Fig. 2 (D) by fastening the fastening nut 15 to the fastening end (11a) of the pipe nut 11 exited through the shaft hole (14a) of the reinforcement bracket 14, to integrate the parts assembled together. Let it be.

상기와 같이 조립되면 도 2(마)와 같이, 대략 "∪"형상의 사이드멤버(1)에 끼워준 후, 강화브래킷(14)의 상단플랜지(14b)를 사이드멤버(1)의 좌우 측면에 스폿(Spot)용접하고, 강화브래킷(14)의 측면플랜지(14c)를 사이드멤버(1)의 바닥면에 스폿(Spot)용접하여 준다. When assembled as described above, as shown in Fig. 2 (e), after inserting into the side member 1 of the substantially "∪" shape, the upper flange 14b of the reinforcing bracket 14 is spot on the left and right sides of the side member (1) Spot welding and spot welding the side flange 14c of the reinforcement bracket 14 to the bottom surface of the side member 1 are carried out.

이때, 스폿(Spot)용접은 상단플랜지(14b)와 측면플랜지(14c)의 끝에서 절곡된 부위를 이용해 이루어진다.In this case, spot welding is performed using a portion bent at the ends of the upper flange 14b and the side flange 14c.

상기와 같이 스폿(Spot)용접으로 강화브래킷(14)이 사이드멤버(1)에 고정됨으로써, 본 실시예에 따른 마운팅장치(10)의 조립작업이 완료되어진다.As the reinforcement bracket 14 is fixed to the side member 1 by spot welding as described above, the assembling work of the mounting apparatus 10 according to the present embodiment is completed.

도 3(가)는 본 실시예에 따른 마운팅장치(10)의 조립 단면도로서, 도시된 바와 같이 파이프너트(11)를 통해 배터리 체결볼트가 조립되고, 원뿔기둥 형상의 부시(12)가 사이드멤버(1)의 안쪽 공간을 점유하게 된다.3 (a) is an assembly cross-sectional view of the mounting apparatus 10 according to the present embodiment, the battery fastening bolt is assembled through the pipe nut 11 as shown, the conical pillar-shaped bush 12 is the side member It occupies the inner space of (1).

상기와 같은 구조로 인해 도 3(나)와 같이, 마운팅장치(10)에 가해진 배터리 자중(F)은 사이드멤버(1)의 바닥에 밀착된 강화브래킷(14)을 통해 부시(12)로 전달되어 부시(12)를 압축시키게 된다.Due to the above structure, as shown in FIG. 3 (b), the battery weight F applied to the mounting apparatus 10 is transferred to the bush 12 through the reinforcing bracket 14 closely attached to the bottom of the side member 1. Thus, the bush 12 is compressed.

상기와 같이 부시(12)가 압축변형됨으로써, 배터리 자중(F)은 사이드멤버(1)의 바닥으로 직접 작용하는 주 하중과 부시(12)의 전방향으로 분산되어 사라지는 분산하중으로 나누어지게 된다.As the bush 12 compressively deforms as described above, the battery self weight F is divided into a main load acting directly to the bottom of the side member 1 and a distributed load dissipated in all directions of the bush 12.

이러한 부시(12)를 통한 배터리 자중(F)의 분산효과는 사이드멤버(1)의 바닥으로 직접 작용하는 배터리 자중(F)의 크기를 줄여주고, 이로 인해 배터리 자중(F)으로 인한 사이드멤버(1)의 바닥면 처짐(K)이 종래 기술대비 크게 줄어 들 수 있게 된다.Dispersion effect of the battery weight (F) through the bush 12 reduces the size of the battery weight (F) directly acting as the bottom of the side member (1), thereby the side member ( Floor deflection (K) of 1) can be significantly reduced compared to the prior art.

상기와 같이 본 실시예의 마운팅장치(10)는 상하방향으로 가해지는 배터리의 자중에 의한 하중을 탄성재질의 부시(12)를 이용한 전방위 분산으로 하중 집중에 따른 변위를 약 40% ~ 50% 정도 줄여주고, 하중 집중에 따른 내구 저하를 방지하면서 배터리 마운팅 구조에 의한 NVH 가중 원인도 해소될 수 있게 된다.
As described above, the mounting apparatus 10 according to the present embodiment reduces the displacement due to the load concentration by about 40% to 50% by distributing the load by the weight of the battery applied in the vertical direction by the omnidirectional dispersion using the bush 12 of the elastic material. In addition, it is possible to eliminate the cause of the NVH weighting caused by the battery mounting structure while preventing durability deterioration due to load concentration.
