Abstract

PURPOSE: Combining structure for the battery tray of an electric vehicle is provided to reduce the second injury of a driver by preventing a battery tray and a battery assembly from being damaged in case of a collision. CONSTITUTION: A battery tray(5) is fixed to a plate(7) arranged on the bottom of a body, with a bolt(9) and a nut(11). The plate forms a long groove in a length direction. The side of the long groove is corresponding to the size of the bolt and the nut. During a collision, a drive motor pressurizes the battery tray rearward. Then, the bolt is moved to the rear side of the long groove to be separated from the long groove. Thus, the battery tray is easily separated from the plate in case of a collision.

상기한 배터리 트레이(5)는 바디(1)의 저면에 배치되는 플레이트(7)에 고정 결합되는 구조를 가지고 있다.The battery tray 5 has a structure fixedly coupled to the plate (7) disposed on the bottom surface of the body (1).

도2는 도1의 주요부분을 도시한 단면도로서, 바디(1)의 저면에 배치되는 플레이트(7)와, 상기한 플레이트(7)의 저면에 볼트부재(9)에 의하여 체결이 이루어지도록 배터리 트레이를 도시하고 있다.FIG. 2 is a cross-sectional view showing the main part of FIG. 1, wherein the battery 7 is fastened by a bolt member 9 disposed on the bottom surface of the body 7 and the bottom surface of the plate 7. The tray is shown.

상기 배터리 트레이는 프론트 측과 리어측이 각각 플레이트(7)에 볼트 및 너트 부재(9), (11)에 의하여 결합되어 있다.The battery tray has a front side and a rear side coupled to the plate 7 by bolt and nut members 9 and 11, respectively.

상기 플레이트(7)는, 도3에 도시하고 있는 바와 같이, 차체(1)의 길이 방향으로 장홈(13)이 형성되어 있다. 상기 장홈(13)은 프론트측이 볼트 및 너트를 체결할 수 있는 크기로 이루어져 있고, 리어측은 볼트 및 너트가 이탈될 수 있도록 프론트 측보다 상대적으로 크기가 크게 되어 있다.As shown in FIG. 3, the plate 7 is provided with a long groove 13 in the longitudinal direction of the vehicle body 1. The long groove 13 has a size that the front side can fasten the bolt and nut, the rear side is relatively larger than the front side so that the bolt and nut can be separated.

도4는 도3의 A-A부를 절개하여 도시한 단면도로서, 배터리 트레이(5)가 바디(1)의 플레이트(7)에 고정되는 상태를 도시하고 있다.FIG. 4 is a cross-sectional view of the A-A section of FIG. 3 and shows a state in which the battery tray 5 is fixed to the plate 7 of the body 1.

상기한 배터리 트레이(5)는 상단부에 볼트공이 형성되어 있다. 그리고 상기 볼트공과 플레이트(7)의 장홈에 볼트가 삽입되어 배터리 트레이와 플레이트가 체결되는 구조로 이루어져 있다.The battery tray 5 has a bolt hole formed at an upper end thereof. And a bolt is inserted into the long groove of the bolt hole and the plate 7 has a structure in which the battery tray and the plate is fastened.

그리고 도5는 도3의 B-B부를 절개하여 도시한 단면도로서, 플레이트(7)에 결합되어 있는 볼트 및 너트가 이탈될 수 있는 홈(13)을 나타내고 있다. 상기 홈(13)은 배터리 트레이(5)가 충돌 등으로 밀리면 플레이트(7)에서 볼트 및 너트가 이탈될 수 있도록 프론트 측보다 더 크게 되어 있다.FIG. 5 is a cross-sectional view of the B-B portion of FIG. 3, and shows the groove 13 through which the bolt and nut coupled to the plate 7 can be detached. The groove 13 is larger than the front side so that the bolts and nuts can be released from the plate 7 when the battery tray 5 is pushed by a collision or the like.

본 발명에 따른 전기 자동차의 배터리 트레이 결합구조의 작동 과정을 상세하게 설명하면 다음과 같다.Referring to the operation of the battery tray coupling structure of the electric vehicle according to the present invention in detail.

우선 배터리 트레이(5)는 플레이트(7)에 형성되어 있는 장홈(13)의 프론트측에 볼트 및 너트에 의하여 결합되어 있다. 이러한 고정상태는 장홈(13)의 폭이 볼트 및 너트와 대응되는 크기로 이루어져 있으므로 견고하게 체결상태를 유지할 수 있다.First, the battery tray 5 is coupled to the front side of the long groove 13 formed in the plate 7 by bolts and nuts. This fixed state is because the width of the long groove 13 is made of a size corresponding to the bolt and nut can be maintained firmly fastened.

그러나 전기자동차가 주행 또는 정차중에 충돌 또는 추돌 사고가 발생하게 되어 자동차의 프론트측에 설치되는 구동모터(3)가 리어측으로 밀리면, 구동모터(3)가 배터리 트레이(5)를 리어측으로 가압한다. 그러면 배터리 트레이(5) 역시 리어측으로 밀리면서 배터리 트레이(5)와 플레이트(7)를 체결하고 있던 볼트가 플레이트(7)의 장홈(13)의 리어측, 즉 폭이 큰쪽으로 이동한다. 그러면 볼트(9)는 플레이트(7)의 장홈으로 부터 이탈되어 아래측, 즉 지면으로 떨어진다. 따라서 배터리 트레이(5)가 전기자동차의 바디 플레이트(7) 하방으로 이탈되는 것이다.However, when an electric vehicle is driven or stopped, a collision or collision accident occurs, and when the driving motor 3 installed on the front side of the vehicle is pushed to the rear side, the driving motor 3 presses the battery tray 5 to the rear side. Then, while the battery tray 5 is also pushed to the rear side, the bolt which fastened the battery tray 5 and the plate 7 moves to the rear side of the long groove 13 of the plate 7, ie, the width is larger. The bolt 9 is then separated from the long groove of the plate 7 and falls down, ie to the ground. Therefore, the battery tray 5 is separated below the body plate 7 of the electric vehicle.

상기한 본 발명에 따른 전기 자동차의 배터리 트레이 결합구조는, 추돌 또는 충돌 사고 발생시에 배터리 트레이가 바디의 플레이트로부터 이격되어 차량에서 분리되어 배터리 액에 의한 승차자의 2차 상해를 방지하여 피해를 최소로 줄임으로서 안전을 도모할 수 있다.The battery tray coupling structure of the electric vehicle according to the present invention, the battery tray is separated from the vehicle from the plate of the body in the event of a collision or collision accident is separated from the vehicle to prevent the secondary injury of the rider by the battery fluid to minimize damage By reducing, safety can be achieved.
