본 고안은 전기 자동차용 안전 범퍼에 관한 것으로, 이를 보다 상세하게 설명하면, 조선 산업 등의 대규모 산업현장에서 자재 이송이나 작업자 이동용으로 사용하는 전기 자동차가 운행 중 타물체와의 충돌시에 상기 범퍼(bumper)가 차체쪽으로 밀리면서 충격을 흡수함에 따라 물적 및 인적 피해를 감소시키게 되는 것이다.The present invention relates to a safety bumper for an electric vehicle, which will be described in more detail, when the electric vehicle used for material transfer or worker movement in a large industrial field such as shipbuilding industry is in collision with another object during operation. As the bumper is pushed towards the body, it absorbs the impact, reducing physical and human damage.

종래에는 자동차가 충돌시에 차체가 손상되고 탑승자가 다치는 사고를 방지하고자 자동차의 앞, 뒤측단부에 범퍼를 장착하였으나, 이는 차체에 고정 설치됨으 로서 충격 흡수율이 낮아 경미한 충돌사고시에도 자동차가 손상되고 탑승자까지 다치는 경우가 있었다.Conventionally, bumpers were mounted on the front and rear end of the car to prevent accidents when the car was damaged and the occupant was injured.However, since it is fixedly installed on the car body, the shock absorption is low and the car is damaged even in a minor crash. There was a case of injury.

본 고안은 상기의 문제점을 해결하고자 안출한 것으로서,The present invention has been made to solve the above problems,

이의 고안요지는 산업용 전기 자동차용 안전 범퍼의 내측 중앙부에 연결핀에 의해 부착된 작동간이 차체의 선단부에 설치된 직선베어링(LM Bearing)에 삽입되며, 차체 내부에는 상기 작동간과 일정간격을 두고 기계적 센서를 설치하되, 이센서는 밧데리와 구동모터에 각각 연결되고, 상기 작동간의 좌우 양측에는 각각 가스로 작동되는 업쇼버를 연결핀에 의해 장착하여 차체와 연결되게 구성한 것인바 상기 자동차가 타물체와 충돌시, 상기 범퍼가 업쇼버에 의해 차체쪽으로 밀리면서 충격을 흡수하고 아울러 작동간이 상기 센서와 접촉함에 따라 브레이크가 작동될 뿐만 아니라 전원이 차단되어 정지함에 따라 2차 사고를 방지할 수 있게 한 것이다.The invention is inserted into a linear bearing (LM Bearing) installed at the front end of the vehicle body by an operation pin attached to the inner central part of the safety bumper for an industrial electric vehicle. The sensor is connected to the battery and the driving motor, respectively, and is configured to be connected to the vehicle body by mounting a gas-operated absorber by connecting pins on the left and right sides of the operation, respectively, when the vehicle collides with another object. In addition, the bumper is pushed toward the vehicle body by the absorber to absorb the shock and at the same time, the brake is operated when the operation contacts the sensor, and the secondary accident is prevented when the power is cut off and stopped.

본 고안은 조선소와 같은 대형 산업현장에서 자재이송이나 작업용으로 사용하는 무공해 차량인 전기자동차에 장착되는 안전 범퍼에 관한 것이다.The present invention relates to a safety bumper mounted on an electric vehicle, which is a pollution-free vehicle used for material transfer or work in a large industrial site such as a shipyard.

이를 도면에 의거하여 상세하게 설명하면 다음과 같다.This will be described in detail with reference to the drawings as follows.

도2에서와 같이 상기 범퍼 몸체(1)는 양쪽 끝단부가 차체쪽으로 약간 휘어진 형상이되, 이의 내측 중앙부에는 작동간(2)이 연결핀(6)에 의해 범퍼몸체(1)에 좌우로 두개 부착되고, 상기 작동간(2)을 삽입하여 가이드 역할 및 전, 후작동을 원활하게 하는 직선베어링(LM 베어링)(3)을 차체(9)의 끝단부에 설치하고, 차체(9)의 내부에는 상기 작동간(2)의 끝단에서 일정한 간격(10mm 정도)을 띄운 곳에 접촉시 작동하는 기계적 센서(4)를 설치하되, 이 센서(4)는 밧데리(7)와 구동모터(8)에 연결되게 하고, 상기 작동간(2)의 좌, 우 양측에는 가스(gas)로 작동되는 완충장치인 업쇼버(5)를 연결핀(6)으로 몸체(1)에 각각 장착하여 차체(9)와 연결되게 설치한 구조이다.As shown in Fig. 2, the bumper body 1 has a shape in which both ends thereof are slightly curved toward the vehicle body, and an inner center portion thereof has two operation bars 2 attached to the bumper body 1 left and right by a connecting pin 6. And a linear bearing (LM bearing) 3 inserted into the end of the vehicle body 9 for inserting the operation section 2 to facilitate the guide role and the front and rear operations. At the end of the operation (2) is installed a mechanical sensor (4) which operates when contacted with a certain distance (about 10mm), which is connected to the battery (7) and the drive motor (8) In addition, the left and right sides of the operation (2) are connected to the vehicle body (9) by mounting the absorber (5), which is a shock absorber operated by gas, on the body (1) with connecting pins (6), respectively. It is a structure installed very much.

상기와 같이 구성된 본 고안의 실시예는 다음과 같다.An embodiment of the present invention configured as described above is as follows.

상기한 전기자동차가 운행중에 타물체와 정면으로 충돌할 경우에는 범퍼몸체(1)의 양측에 장착된 업쇼버(5)가 충격을 흡수하여 완충작용을 함과 동시에 범퍼몸체(1)가 차체(9)쪽으로 뒤로 밀리면서 상기한 작동간(2)이 센서(4)와 접촉함에 따라 브레이크가 작동될 뿐만 아니라 축전용 밧데리(7)에서 구동모터(8)로의 전원 공급을 차단함으로서 차체(9)가 멈추어 탑승자가 다치는 등의 2차 사고를 방지한다. 상기한 범퍼 몸체(1)의 좌측 또는 우측의 임의의 방향으로 타물체와 충돌시에도 연결핀(6)에 의해 충돌한 쪽의 업쇼버(5)와 작동간(2)이 작동한다.〈도3 참조〉When the electric vehicle collides with another object while driving, the absorber 5 mounted on both sides of the bumper body 1 absorbs shock and cushions the bumper body 1 while the vehicle body ( 9, the brake is not only activated when the above-described operation 2 comes into contact with the sensor 4, but also the power supply from the storage battery 7 to the drive motor 8 is pushed backward. Stops to prevent secondary accidents such as injuring the occupants. Even when the bumper body 1 collides with the other object in any direction on the left or right side, the absorber 5 on the side collided by the connecting pin 6 and the operation 2 are operated. 3 Reference>

그리고 가벼운 충돌시에는 상기 범퍼몸체(1)와 충돌한 타물체를 제거하면 상기한 업쇼버(5)의 복원력에 의해 상기의 범퍼 몸체(1)가 다시 원상태로 복귀한다.In the case of a light collision, when the other object collided with the bumper body 1 is removed, the bumper body 1 is returned to its original state by the restoring force of the absorber 5 described above.

상기한 바와 같이, 본 고안은 전기 자동차용 안전 범퍼에 관한 것으로서, 상기 자동차가 타물체와 임의의 방향에서 충돌시에도 범퍼몸체(1)의 업쇼버(5)가 완충작용을 하고 아울러 작동간(2)이 센서(4)와 접촉됨에 따라 브레이크가 작동되고 전원이 차단되어 정지함으로서 차체(9)와 탑승자의 사고를 방지할 뿐만 아니라 가 벼운 충돌시에는 충돌한 물체를 제거하면 범퍼몸체(1)가 다시 복원되므로 매우 실용적인 효과가 있는 것이다.As described above, the present invention relates to a safety bumper for an electric vehicle, in which the absorber 5 of the bumper body 1 cushions and operates between the vehicle and the vehicle in an arbitrary direction. 2) the brakes are actuated in contact with the sensor 4, the power is cut off and stopped to prevent the accident of the vehicle body 9 and the occupant, and in case of a light collision, the bumper body 1 is removed by removing the collided object. Is restored again, which has a very practical effect.
