즉, 배터리 트레이(3)는 배터리 팩(5)을 탑재한 상태에서 차체(1)의 하측으로부터 상방향으로 삽입되어 차체에 고정 장착된다.That is, the battery tray 3 is inserted upward from the lower side of the vehicle body 1 in a state where the battery pack 5 is mounted and fixedly mounted to the vehicle body.

이렇게 배터리 트레이(3)에 탑재된 배터리 팩(5)은 전기자동차의 동력 발생장치(미도시)에 전원을 공급할 수 있도록 복수개의 배터리 셀로 구성된다.The battery pack 5 mounted on the battery tray 3 is configured of a plurality of battery cells to supply power to a power generator (not shown) of the electric vehicle.

상기와 같은 배터리 팩(5)을 배터리 트레이(3)상에 탑재한 전기자동차는 차량의 무게가 내연기관을 장착한 차량에 비하여 상대적으로 무거워서 선회시 무게중심 이동에 따른 차량의 롤링이 증대되는 경향이 있다.The electric vehicle equipped with the battery pack 5 as described above on the battery tray 3 is relatively heavy as compared to a vehicle equipped with an internal combustion engine, so that rolling of the vehicle due to the movement of the center of gravity during turning is increased. There is this.

이러한 차량의 롤링을 감소시키는 구성 및 방법에는 다양한 것이 있을 수 있으나, 본 실시예에서는 차량의 운행 상태에 따라 이동하는 무게 중심을 안정시키는 것을 예시한다.There may be a variety of configurations and methods for reducing the rolling of the vehicle, but this embodiment illustrates stabilizing the moving center of gravity according to the driving state of the vehicle.

즉, 본 실시예는 차량 선회시 무게 중심의 이동으로 차체(1)가 상승하는 측이 있을 때, 이 쪽으로 배터리 팩(5)을 이동시켜, 차체(1)의 상승을 억제시켜 롤링을 감소시키는 것이다.That is, in the present embodiment, when there is a side in which the vehicle body 1 rises by moving the center of gravity during the vehicle turning, the battery pack 5 is moved to this side, thereby suppressing the rise of the vehicle body 1 to reduce rolling. will be.

이를 위하여 배터리 트레이(3)상에서 배터리 팩(5)을 이동시키도록 배터리 팩(5)과 차체(1)사이에 이동수단을 구비한다.To this end, a moving means is provided between the battery pack 5 and the vehicle body 1 to move the battery pack 5 on the battery tray 3.

이 이동수단은 롤링을 어떠한 방법으로 감소시키느냐에 따라 다양하게 형성될 수 있으나, 본 실시예에서는 배터리 팩(5)을 차폭 방향으로 이동시키게 하는 것을 예시하므로 직선 운동하는 랙(7)과 이 랙(7)이 직선 운동하도록 모터(M)의 회전 운동에 따라 회전 운동하는 피니언(9)으로 구성된 것을 예시한다. 상기 모터(M)는 별도의 제어 수단(도시생략)에 따라 제어될 수 있는 데, 예를들면, 상기 제어 수단은 각각의 휠측에 배치되어 해당 휠측의 차체 높이의 변화를 감지하는 다수의 차고센서와, 이 차고센서로부터 신호를 전달받아 상기 모터(M)의 회전방향을 제어하는 컨트롤러로 이루어질 수 있으나, 이에 한정되지 않고 다른 방식으로 구성됨이 간으하다.The moving means may be formed in various ways depending on how the rolling is reduced, but in this embodiment, since the battery pack 5 is moved in the vehicle width direction, the rack 7 and the rack (which are linearly moved) are illustrated. 7 illustrates that the pinion 9 rotates in accordance with the rotational motion of the motor M such that the linear motion 7 is linear. The motor M may be controlled according to separate control means (not shown). For example, the control means may be disposed on each wheel side to detect a change in the height of the vehicle body on the corresponding wheel side. And, by receiving a signal from the height sensor may be made of a controller for controlling the rotation direction of the motor (M), but is not limited to this is simply configured in other ways.

즉, 랙(7)은 배터리 팩(5)의 일측, 즉 상단에 그 길이가 차폭 방향을 향하도록 배치되어 배터리 팩(5)에 고정되고, 피니언(9)은 이 랙(7)에 치합되고 모터(M)와 함께 정역회전할 수 있도록 장착된다.That is, the rack 7 is disposed on one side of the battery pack 5, that is, the upper end thereof in the vehicle width direction and fixed to the battery pack 5, and the pinion 9 is engaged with the rack 7. It is mounted so that it can rotate forward and backward with the motor (M).

한편, 차량의 운행 상태에 따라 제어 수단에 의해 제어되는 모터(M)의 구동에 따라 차폭 방향으로 이동하는 배터리 팩(5)이 더욱 원활하게 이동하도록 배터리 팩(5)과 배터리 트레이(3)상에는 가이드 수단이 제공된다.On the other hand, on the battery pack 5 and the battery tray 3 so that the battery pack 5 moving in the vehicle width direction moves smoothly according to the driving of the motor M controlled by the control means according to the driving state of the vehicle. Guide means are provided.

이 가이드 수단은 도 2에 도시된 바와 같이, 롤러(11)와 레일(13)로 구성되며, 상기 롤러(11)는 배터리 팩(5)의 하측에 설치되고, 레일(13)은 이 롤러(11)의 대향측 배터리 트레이(3)상에 설치된다.This guide means consists of a roller 11 and a rail 13, as shown in FIG. 2, which roller 11 is installed under the battery pack 5, and the rail 13 is a roller ( 11 is installed on the battery tray 3 on the opposite side.

그리고 상기 레일(13)은 배터리 팩(5)의 원활한 이동을 위하여 전후방에 복수 설치되고, 롤러(11)는 상기 레일(13)의 일측에 각각 복수로 설치됨이 바람직하다.In addition, the rail 13 may be installed in plural in front and rear to smoothly move the battery pack 5, and the roller 11 may be installed in plural on one side of the rail 13.

상술한 바와 같이 구성되는 전기자동차 롤링 저감장치를 구비한 전기자동차로 주행하게 되면, 차체(1)는 도 3에 도시된 바와 같이 현가장치(15,17)에 의하여 바퀴(19,21)상에 평행한 상태를 유지한다.When driving in an electric vehicle having an electric vehicle rolling reduction device configured as described above, the vehicle body 1 is mounted on the wheels 19 and 21 by suspensions 15 and 17 as shown in FIG. Stay parallel.

그러나 상기 전기자동차로 선회 주행하게 되면(도 4에서 좌측으로 선회한다고 가정), 차체(1)는 도 4에 도시된 바와 같이 선회 반경의 외측(우측)으로 기울게 된다.However, when turning in the electric vehicle (assuming turning to the left in FIG. 4), the vehicle body 1 is inclined to the outside (right side) of the turning radius as shown in FIG. 4.

따라서 차체(1)의 일측(좌측)은 상승되어 차량의 무게 중심이 선회 외측(우측)으로 이동하게 된다.Therefore, one side (left side) of the vehicle body 1 is raised so that the center of gravity of the vehicle moves to the outside of the turning side (right side).

이 때, 상기 모터(M)을 작동시키면, 피니언(9)이 구동되어 이에 치합된 랙(7)을 선회 내측(좌측)으로 이동시켜 결국 배터리 팩(5)을 선회 내측(좌측)으로 이동시킨다.At this time, when the motor (M) is operated, the pinion (9) is driven to move the rack 7 engaged to the inside of the turning (left) to eventually move the battery pack 5 to the inside of the turning (left). .

따라서 화살표 방향으로 하중이 증대되는, 즉 선회 방향의 내측인 차체(1)측으로 무게 중심을 이동시키므로 차체(1)는 보다 안정된 자세를 유지하게 되어 롤링을 감소시킨다(적어도 배터리 팩(5)에 의하여 선회 외측으로 무게 중심이 이동하여 발생되는 차량의 롤링부분만큼).Therefore, since the load is increased in the direction of the arrow, that is, the center of gravity is moved toward the vehicle body 1 that is in the turning direction, the vehicle body 1 maintains a more stable posture and reduces rolling (at least by the battery pack 5). As the rolling part of the vehicle caused by the movement of the center of gravity out of the turn.

상기와 같은 선회 운행 완료시에는 모터(M)를 역방향으로 구동시켜 배터리 팩(5)을 원상태로 복귀시킨다.Upon completion of the turning operation as described above, the motor M is driven in the reverse direction to return the battery pack 5 to its original state.

상기와 같이 배터리 팩(3)이 배터리 트레이(3)상에서 차폭 방향으로 이동할 때, 배터리 팩(3)의 하측에 설치된 롤러(11)는 레일(13)의 지지를 받으면서 원활하게 지지된다.When the battery pack 3 moves in the vehicle width direction on the battery tray 3 as described above, the roller 11 installed below the battery pack 3 is smoothly supported while being supported by the rail 13.

상술한 바와 같이 본 발명에 따른 전기자동차 롤링 저감장치는 차량의 주행 상태에 따라 이동수단이 배터리 팩을 이동시켜 차량의 롤링을 감소시키므로 선회 안정성을 향상시킬 수 있다.As described above, the electric vehicle rolling reduction device according to the present invention can improve the turning stability because the moving means reduces the rolling of the vehicle by moving the battery pack according to the driving state of the vehicle.

즉, 본 발명은 선회시 이동수단이 작동하여 차체가 상승하는 방향으로 배터리 팩을 이동시켜 차체가 상스하는 측으로 무게 중심을 이동시키므로 차량의 롤링을 감소시켜 선회 안정성을 향상 시킨다.That is, the present invention improves the turning stability by reducing the rolling of the vehicle because the moving means operates during the turning to move the battery pack in the direction in which the vehicle body rises to move the center of gravity to the side where the vehicle body is upward.
