The upper end of the side end portion (4) is bent and provided with a bolt insertion hole (4a) in the upper portion, the bolt insertion hole (2a) of the member (2) and the bolt insertion hole (4a) of the tray (4) bolts (5) ) And the nut 6, the structure in which one side of the member 2 and the upper side end of the tray 4 are coupled to only one side by the bolt 5 and the nut 6, and the load of the battery 3 is increased. And significant stress occurred at the joint portion of the member 2 and the tray 4 and the bent portion at the side of the tray 4 due to the vibration of the vehicle and the like, which may cause sagging and detachment of the tray 4.

본 고안의 목적은 상기와 같은 문제점을 해소하기 위하여, 멤버와 트래이의 결합부에 가해지는 집중 하중을 분산하여, 트래이의 처짐 및 이탈을 방지하는 구조를 제공하는데 있다.An object of the present invention is to provide a structure for preventing the deflection and departure of the tray by distributing the concentrated load applied to the coupling portion of the member and the tray in order to solve the above problems.

상기의 목적을 달성하기 위하여 본 고안은, 파이프를 내장한 멤버와 보조브라켓을 결합한 트래이를 상기 파이프를 관통하여 볼트와 너트로 결합하였다.In order to achieve the above object, the present invention, through the pipe coupled to the tray and the member and the auxiliary bracket incorporating the pipe was coupled to the bolt and nut.

이하, 본 고안의 구성을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration of the present invention in detail with reference to the accompanying drawings as follows.

제3도 및 제4도에서와 같이 본 고안은, 전기 자동차의 배터리(3)를 장착하기 위한 멤버(10)와 트래이(20)의 결합 구조로, 플로워패널(1)의 저면 양측으로 결합되는 멤버(10)의 내부에 지지브라켓(31)을 장착한 보강파이프(30)를 내설하고, 상기 보강파이프(30)와 연통하도록 멤버(10)의 양측으로 볼트결합공(11)을 형성하며, 배터리(3) 수납 공간을 갖는 트래이(20)의 측면(22)이 상기 멤버(10)의 외측으로 결합되며, 그 상부로는 멤버(10)의 볼트결합공(11)과 연통하는 볼트결합공(21)을 형성하고, 상기 트래이(20)의 볼트결합공(21) 및 멤버(10)의 볼트결합공(11)과 보강파이프(30)를 연통하여 볼트(40)와 너트(41)로 결합하는 구조를 갖는다.As in FIGS. 3 and 4, the present invention is a coupling structure of the tray 10 and the member 10 for mounting the battery 3 of the electric vehicle, which is coupled to both sides of the bottom surface of the floor panel 1. Internally reinforcing pipe 30 mounted with a support bracket 31 inside the member 10, and forming bolt coupling holes 11 on both sides of the member 10 so as to communicate with the reinforcing pipe 30, Side 22 of the tray 20 having a battery (3) storage space is coupled to the outside of the member 10, the upper portion of the bolt coupling hole in communication with the bolt coupling hole 11 of the member 10 (21) is formed, and the bolt coupling hole (21) of the tray 20 and the bolt coupling hole (11) of the member 10 and the reinforcing pipe (30) to communicate with the bolt (40) and the nut (41).
