Description
본 발명은 전기자동차의 배터리팩홀더 자동분리장치에 관한 것으로, 더욱 상세하게는 전기자동차의 운행중 외부로부터 인가되는 충격이나 과전류에 의하여 리튬이온 고전압배터리에 화재가 발생되어 고전압배터리의 온도가 정상온도 이상으로 상승되면 고전압배터리가 탑재되는 배터리팩홀더가 차체로부터 자동적으로 분리되도록 함으로써 탑승객의 인명손실을 방지할 수 있도록 하고, 재산상의 손실을 최소화 할 수 있도록 한 전기자동차의 배터리팩홀더 자동분리장치에 관한 것이다. The present invention relates to an automatic separation device for the battery pack holder of an electric vehicle. More specifically, the present invention relates to an automatic separation device for a battery pack holder of an electric vehicle. More specifically, a fire occurs in a lithium-ion high-voltage battery due to an external shock or overcurrent while the electric vehicle is in operation, and the temperature of the high-voltage battery exceeds the normal temperature. Regarding the automatic battery pack holder separation device for electric vehicles, which prevents loss of life for passengers and minimizes property damage by automatically separating the battery pack holder on which the high-voltage battery is mounted from the vehicle body when the voltage rises. will be.
일반적으로, 전기자동차, 하이브리드 전기자동차, 연료전지 자동차 및 친환경 자동차들은 모두 전기모터를 이용하여 차량을 구동시키도록 구성되며, 전기모터에 구동전력을 제공하는 고전압 배터리팩을 필수적으로 구비하고 있다.In general, electric vehicles, hybrid electric vehicles, fuel cell vehicles, and eco-friendly vehicles are all configured to drive the vehicle using an electric motor, and are essentially equipped with a high-voltage battery pack that provides driving power to the electric motor.
한편, 도 1에 도시된 바와 같이, 상기한 전기자동차(10)에서 차체(11)의 하부에는 별도의 배터리팩홀더(12)가 중첩되게 설치되는데, 상기 배터리팩홀더(12)의 내부에는 리튬이온 고전압 배터리팩(13)이 내장되게 탑재되고, 상기 배터리팩홀더(12)의 상부면에는 다수개의 고전압배터리 연결소켓(BMS::Battery Management System:14)이 형성된다.Meanwhile, as shown in FIG. 1, in the electric vehicle 10, a separate battery pack holder 12 is installed to overlap the lower part of the vehicle body 11, and lithium is stored inside the battery pack holder 12. An ion high-voltage battery pack 13 is built-in, and a plurality of high-voltage battery connection sockets (BMS::Battery Management System: 14) are formed on the upper surface of the battery pack holder 12.
그러나, 이와 같은 종래의 전기자동차의 배터리팩홀더(13)의 구성에서는 전기자동차의 운행중에 외부로부터 예기치 않은 충격력이 인가되거나 과전류에 의하여 리튬이온 고전압 배터리팩(13)에 화재가 발생되는 경우에 배터리팩홀더를 자동적으로 분리할 수 있도록 하는 장치가 별도로 설치되어 있지 않기 때문에 배터리팩홀더에서 발생된 화재의 화염은 순식간에 차체 및 차량의 내부로 순식간에 옮겨 붙으면서 탑승자가 안전을 크게 위협하게 된다는 심각한 문제가 있으며, 차량 전체가 전소되는 경우에 재산상의 손실 또한 막대하다는 문제가 있다. However, in the configuration of the battery pack holder 13 of such a conventional electric vehicle, if an unexpected impact force is applied from the outside while the electric vehicle is in operation or a fire occurs in the lithium-ion high-voltage battery pack 13 due to overcurrent, the battery Since there is no separate device installed to automatically separate the pack holder, the flames of the fire generated from the battery pack holder can quickly spread to the body and interior of the vehicle, posing a serious threat to the safety of the occupants. There is a problem, and the problem is that if the entire vehicle is burned down, the property loss is also enormous.
한편, 상기한 전기자동차의 배터리팩과 관련된 기술로서 대한민국 공개특허 제10-2014-0045778호(명칭: 승용 전기차의 고전압 배터리팩, 이하 '관련기술'이라 함)가 제안되었다.Meanwhile, Republic of Korea Patent Publication No. 10-2014-0045778 (name: high-voltage battery pack for passenger electric vehicles, hereinafter referred to as 'related technology') has been proposed as a technology related to the battery pack of the electric vehicle described above.
상기 관련기술은 '차체를 구성하는 언더플로어패널 하부의 불용공간을 적극적으로 활용하여 보다 많은 양의 배터리 모듈을 설치할 수 있도록 하고, 배터리 모듈의 냉각 성능을 한층 더 향상시킬 수 있도록 하는 한편, 러기지룸을 충분하게 확보할 수 있도록 한 것'이다.The above-mentioned related technology actively utilizes the unused space below the underfloor panel that makes up the vehicle body to enable the installation of a larger amount of battery modules, and further improves the cooling performance of the battery modules. This is to ensure that sufficient rooms are secured.
상기한 관련기술에 따르면, 보다 많은 양의 배터리모듈의 설치가 가능하다는 잇점은 있으나, 운행중 배터리에 화재가 발생하는 경우에 화재발생지점의 부품을 분리할 수 있는 장치가 전혀 마련되어 있지 않아 탑승자의 안전을 도모할 수 었는 것은 물론, 재산상의 막대한 손실을 방지할 수 없다는 심각한 문제가 있는 것이다.According to the above-mentioned related technology, there is an advantage in that a larger amount of battery modules can be installed, but in case a fire occurs in the battery during operation, there is no device to separate the parts at the point of fire, thereby compromising the safety of the passengers. Of course, there is a serious problem in that it is not possible to prevent massive property losses.

본 발명의 다른 목적은 화재시 고전압의 패배터리팩홀더가 자동분리되도록 함으로써 고전압배터리는 지면에 떨어지고 차체는 동력이 없으므로 밀어서 고전압배터리로부터 이동하면 탑승객의 인명손실을 방지할 수 있도록 하고, 재산상의 손실을 최소화 할 수 있도록 한 새로운 전기자동차의 배터리팩홀더 자동분리장치를 제공하는 것이다.Another object of the present invention is to automatically separate the high-voltage battery pack holder in the event of a fire, so that the high-voltage battery falls on the ground and the car body has no power, so it is possible to prevent loss of life for passengers and property damage by pushing and moving from the high-voltage battery. The purpose is to provide an automatic separation device for the battery pack holder of a new electric vehicle that minimizes .

A temperature sensor that outputs an electrical signal when the temperature rises; When installed on the inside of the vehicle body at the position facing the connector, a cylinder (magnetic force) that becomes magnetic due to the current applied according to the control operation of the main controller according to the electrical signal output from the temperature sensor in the event of a fire. A square-shaped electromagnet; It is made of a metal material sensitive to magnetic force, and the outer end is inserted into the inside of the electromagnet, and the inner end is detachably coupled to the battery pack holder and a connector protruding outward from both sides of the vehicle body, and the magnetic force of the electromagnet is applied. An operating piece that moves linearly in an inward or outward direction and is coupled to or separated from the connector depending on whether the operating piece is connected to the connector; The outer end is fixedly installed on the inner center line of the electromagnet, and the inner end is inserted into the spring receiving groove formed on the outer end of the operating piece inserted inside the electromagnet. When the electromagnet is magnetic and the operating piece is pulled outward, When it is compressed and the magnetic force of the electromagnet is lost, it has the characteristic of including a spring that elastically returns in the inward direction and allows the connector to be inserted and coupled to the inner end of the operating piece.

본 발명에 따르면, 전기자동차의 운행중에 외부로부터 인가되는 충격이나 과전류에 의하여 리튬이온 고전압배터리에 화재가 발생되어 고전압배터리의 온도가 정상온도 이상으로 상승되면 고전압배터리가 탑재되는 배터리팩홀더가 차체로부터 자동적으로 분리되기 때문에 고전압배터리는 지면에 떨어지고 차체는 동력이 없으므로 밀어서 고전압배터리로부터 이동하면 탑승객의 인명손실을 방지할 수 있는 것은 물론, 재산상의 손실 또한 최소화할 수 있다는 효과가 있다.According to the present invention, when a fire occurs in the lithium-ion high-voltage battery due to an external shock or overcurrent while the electric vehicle is in operation and the temperature of the high-voltage battery rises above the normal temperature, the battery pack holder on which the high-voltage battery is mounted is removed from the vehicle body. Because it is automatically separated, the high-voltage battery falls to the ground and the car body has no power, so pushing it to move away from the high-voltage battery has the effect of preventing loss of life for passengers and minimizing property damage.

상기 전자석(60)을 구성하는 전자석코일(62)이 자력을 띠게 되면, 상기 작동편(70)이 자력에 의하여 외측으로 당겨짐과 동시에 스프링(80)이 압축되고, 차체(11) 및 배터리팩홀더(12)의 양쪽 측면으로부터 돌출된 상태에서 상기 작동편(70)상의 연결구삽입홈(71)에 끼워져 결합되어 있던 연결구(40)가 빠지면서 배터리팩홀더(12)가 자동적으로 분리되는 것이다.When the electromagnet coil 62 constituting the electromagnet 60 becomes magnetic, the operating piece 70 is pulled outward by magnetic force and the spring 80 is compressed, and the vehicle body 11 and the battery pack holder The battery pack holder 12 is automatically separated as the connector 40, which is inserted and coupled to the connector insertion groove 71 on the operating piece 70 while protruding from both sides of the device 12, is removed.
이 상태에서 차체(11)만을 밀어 안전한 곳으로 이동시키면 화재가 발생된 배터리팩홀더(12)만이 남게 됨으로 탑승자의 안전을 도모할 수 있으며, 차체의 전소에 따라 재산상의 손실 또한 방지할 수 있게 되는 것이다. In this state, if only the vehicle body (11) is pushed and moved to a safe place, only the battery pack holder (12) where the fire occurred will remain, thereby ensuring the safety of the occupants and preventing property damage due to the vehicle body being completely burned down. will be.
