도 1을 참조하면, 본 발명에 따른 전기동력 트랙터는 배터리팩(110)을 앞차축 프레임(120)의 중앙 상부 공간에 배치하게 된다.Referring to FIG. 1, in the electric power tractor according to the present invention, the battery pack 110 is disposed in the central upper space of the front axle frame 120.

이때, 상기 앞차축 프레임(120)은 한 쌍의 금속판재가 트랙터의 주행방향에 일정거리 이격되어 대향 설치되고, 길이방향의 전방과 후방이 각각 막혀진 틀구조로 형성하게 된다.At this time, the front axle frame 120 is a pair of metal plate material is installed to be opposed to a predetermined distance spaced apart in the traveling direction of the tractor, and the front and rear in the longitudinal direction is formed in a frame structure respectively blocked.

이때, 상기 앞차축 프레임(120)의 마주하는 내측면에는 상부레일(160) 및 하부레일(170)이 각각 평행하게 설치되고, 상기 상부레일(160)과 하부레일(170) 사이에 슬라이딩 안내되도록 배터리팩(110)이 설치된다.At this time, the upper rail 160 and the lower rail 170 are installed in parallel to the inner surface facing the front axle frame 120, so as to slide between the upper rail 160 and the lower rail 170. The battery pack 110 is installed.

상기 배터리팩(110)은 상부레일(160)과 하부레일(170)에 가이드된 상태로 차체의 전, 후방향으로 부드럽게 슬라이드 이동된다.The battery pack 110 is slidably moved forward and backward of the vehicle body while being guided to the upper rail 160 and the lower rail 170.

이때, 상기 배터리팩(110)에는 상부레일(160)과 하부레일(170) 사이를 부드럽게 구름 운동하도록 슬라이딩 롤러(140)가 설치된다.At this time, the battery pack 110 is provided with a sliding roller 140 to smoothly move between the upper rail 160 and the lower rail 170.

상기 슬라이딩 롤러(140)는 배터리팩(110)의 양측 길이방향을 따라 다수가 설치될 수도 있고, 슬라이딩 롤러(140) 사이는 등 간격 떨어져 배치되도록 할 수 있다.The sliding roller 140 may be provided in a plurality along the longitudinal direction of both sides of the battery pack 110, it may be arranged so as to be spaced apart between the sliding roller 140.

상기한 바와 같은 배터리(110)를 트랙터 차량에서 탈거시 앞차축 프레임(120)의 전방에 설치되는 도어부(130)를 열고, 배터리(110)를 잡아 당겨서 탈거되도록 할 수 있다.When the battery 110 as described above is removed from the tractor vehicle, the door unit 130 installed at the front of the front axle frame 120 may be opened, and the battery 110 may be pulled out to be removed.

이때, 상기 도어부(130)는 하단이 앞차축 프레임(120)에 힌지 결합되어 상기 힌지 결합축을 중심으로 회동되는 구조로 이루어진다.In this case, the door 130 has a structure in which the lower end is hinged to the front axle frame 120 is rotated around the hinge coupling shaft.

이때, 상기 도어부(130) 내면에는 보조슬라이딩 롤러(150)가 설치되어 배터리팩(110)의 저면을 지지시켜 배터리팩(110)의 인출을 돕게 된다.At this time, the auxiliary sliding roller 150 is installed on the inner surface of the door part 130 to support the bottom of the battery pack 110 to help the battery pack 110 to be pulled out.

상기 보조슬라이딩 롤러(150)는 한 쌍이 좌우 양측에 나란히 설치될 수 있다.The auxiliary sliding roller 150 may be installed in a pair side by side on both left and right sides.

이와 같은 도어부(130)는 충분한 강성을 갖도록 제작됨으로써, 앞차축 프레임(120)과 함께 배터리팩(110)을 지지하는 메인프레임으로서의 역할을 수행하게 된다.The door 130 is manufactured to have sufficient rigidity, and thus serves as a main frame supporting the battery pack 110 together with the front axle frame 120.

이때, 상기 도어부(130)와 앞차축 프레임(120) 사이는 볼트체결 방식에 의해 고정 결합되도록 할 수 있다.
At this time, the door unit 130 and the front axle frame 120 may be fixedly coupled by a bolting method.

도 5a, 5b는 본 발명에 따른 앞차축으로부터 배터리팩을 분리시키는 과정을 차례대로 도시한 측면도이다.5A and 5B are side views illustrating a process of separating the battery pack from the front axle according to the present invention.

도 5a, 5b를 참조하면, 상부레일(160)과 하부레일(170)을 따라 인출되던 배터리팩(110)이 상부레일(160)의 걸림턱부(161)에 멈춰서 인출이 제한되도록 한다.Referring to FIGS. 5A and 5B, the battery pack 110 drawn out along the upper rail 160 and the lower rail 170 stops at the locking jaw portion 161 of the upper rail 160 to limit the extraction.

이는, 배터리팩(110)의 완전 인출로 인한 낙하를 방지하기 위함이다. This is to prevent the drop due to complete withdrawal of the battery pack 110.

이를 위해 상기 상부레일(160)의 끝단 부근에 상부로 절곡된 걸림턱부(161)를 형성하고, 상기 걸림턱부(161)에 배터리팩(110)에 설치된 슬라이딩 롤러(140)가 들어가 진행을 제한하게 된다.To this end, the locking jaw portion 161 is bent upwardly near the end of the upper rail 160, and the sliding roller 140 installed in the battery pack 110 enters the locking jaw portion 161 to limit the progress. do.

이는 배터리팩(110)이 보조슬라이딩 롤러(150)을 기점으로 전방이 무겁고 후방이 가벼워져 후방이 들리면서, 슬라이딩 롤러(140)가 걸림턱부(161)에 안착되는 것으로서, 슬라이드 진행이 멈춘 상태의 배터리팩(110)의 앞머리를 들어서, 서서히 진행시킴에 따라 배터리팩(110)을 앞차축 프레임(120)으로부터 완전히 탈거할 수 있게 된다.This is because the battery pack 110, the front of the auxiliary sliding roller 150, the front is heavy and the rear is light and the rear is lifted, the sliding roller 140 is seated on the locking jaw 161, the slide progress is stopped Lifting the front of the battery pack 110, as you progress slowly it is possible to completely remove the battery pack 110 from the front axle frame 120.

이때, 상기 상부레일(160)의 끝단 길이를 하부레일(170)의 끝단 길이보다 짧게 형성할 수 있는데, 이는 배터리팩(110)의 후단이 쉽게 레일(160)(170)로부터 벗어나거나 진입되도록 하기 위함이다.
At this time, the end length of the upper rail 160 may be formed to be shorter than the end length of the lower rail 170, so that the rear end of the battery pack 110 is easily escaped or entered from the rails 160 and 170. For sake.

이와 같은 본 발명은 배터리팩(110) 인출시 낙하를 방지할 수 있고, 인출 마지막 단계에서 작업자가 힘조절 및 속도조절을 통해 안전하게 탈거할 수 있게 된다.The present invention as described above can prevent the fall when the battery pack 110 is withdrawn, the operator can be safely removed through the force control and speed control in the final stage of withdrawal.

앞서 살펴본 바와 같은 본 발명은 트랙터의 앞차축 프레임을 이용한 배터리팩을 취부할 수 있는 공간을 마련함으로써, 기존의 차량구조를 크게 변경하지 않고 설치가 가능하고, 앞차축 프레임 상에 슬라이딩 방식의 레일을 형성하고, 상기 레일을 이용해 무거운 배터리팩을 차량에서 손쉽게 분해 및 조립할 수 있게 되어 작업이 편리하고, 배터리 교체시 들어서 이동하거나, 이동 도중 추락으로 인해 작업자가 부상을 당하는 것을 미연에 방지하게 되는 이점을 갖는다.The present invention as described above by providing a space for mounting the battery pack using the front axle frame of the tractor, it is possible to install without significantly changing the existing vehicle structure, the sliding rail on the front axle frame It is easy to disassemble and assemble a heavy battery pack in a vehicle by using the rail, which is convenient for work, and prevents injuries to workers due to falling or moving during battery replacement.
