이하, 본 발명의 구체적인 실시 예를 첨부 도면을 참조하여 상세히 살펴보면 다음과 같다.Hereinafter, specific embodiments of the present invention will be examined in detail with reference to the accompanying drawings.

먼저, 본 발명의 일 실시 예에 따른 배터리 보호구조체의 구성을 도 1 내지 도 7을 통해 살펴보면 다음과 같다.First, the configuration of the battery protection structure according to an embodiment of the present invention is as follows through FIGS. 1 to 7.

본 실시 예에서 전기 자동차의 저면에 장착되는 배터리 본체를 보호하기 위해 조립이 이루어지는 보호커버(10)는 다수개로 분할된 분할 구조를 이루어 배터리 본체(20)에 구성된 알루미늄 보호판(30)에 피스 조립이 이루어지게 된다.In this embodiment, the protective cover 10, which is assembled to protect the battery body mounted on the bottom of the electric vehicle, has a split structure divided into multiple pieces and is assembled into pieces on the aluminum protection plate 30 formed on the battery body 20. It will come true.

이때, 상기 보호커버(10) 내측에는 알루미늄 보호판(30)에 돌출 구비된 볼트머리(40)를 보호하는 볼토 보호쿠션(50) 및 비드(60)를 보호하는 비드 보호쿠션(70)이 각각 구비된 것을 확인할 수 있다.At this time, the inside of the protective cover (10) is provided with a bolt protection cushion (50) that protects the bolt head (40) protruding from the aluminum protection plate (30) and a bead protection cushion (70) that protects the bead (60). You can confirm that it has been done.

즉, 알루미늄 보호판(30)을 배터리 본체(20)에 조립 및 용접 장착하는 과정에서 볼트머리(40)와 비드(60)가 각각 외부로 노출된 구조를 이루게 되며, 이러한 볼트머리(40) 및 비드(60)의 노출을 방지함과 함께 완충 보호하기 위한 스펀지 또는 고무 재질의 볼트 보호쿠션(50) 및 비드 보호쿠션(70)이 각각 보호커버(10) 내부에 구비된다.That is, in the process of assembling and welding the aluminum protection plate 30 to the battery body 20, the bolt head 40 and the bead 60 each form a structure exposed to the outside, and these bolt heads 40 and beads are exposed to the outside. A bolt protection cushion (50) and a bead protection cushion (70) made of sponge or rubber are provided inside the protection cover (10) to prevent exposure of (60) and provide cushioning protection.

또한, 보호커버(10)에는 프레스 작업을 통한 강화 엠보가 이루어질 수 있도록 하는 강도 보강을 위한 보강살(10a)이 타원 형태로 형성된다.In addition, the protective cover 10 is formed with reinforcing spokes 10a in an oval shape for reinforcing strength so that reinforced embossing can be performed through press work.

본 실시 예에서의 보호커버(10)는 6개의 분할형 개별 커버체(11,12,13)가 개별적으로 알루미늄 보호판(30)에 피스 조립이 이루어지게 된다.The protective cover 10 in this embodiment is made up of six split individual cover bodies 11, 12, and 13 individually assembled to the aluminum protective plate 30.

한편, 각 개별 커버체(11,12,13)의 양단부에는 프레스 성형을 통해 배터리 본체(20)와 피스 조립이 이루어질 수 있도록 절곡부(10b,10c)가 연장 구비된 것을 확인할 수 있다.Meanwhile, it can be seen that both ends of each individual cover body (11, 12, and 13) have extended bent portions (10b, 10c) so that the pieces can be assembled with the battery body (20) through press molding.

또한, 보호커버(10)의 저면에는 도 2에서와같이 보호층(10')이 박막으로 코팅 형성되어 비드 보호쿠션(70)과 직접 접촉에 따른 고착현상 방지할 수 있도록 함이 바람직하다. 이때 보호층(10')은 우레탄수지 20~40중량%, 글라스울 10~30중량%, 폴리올레핀 10~30중량%, 실리콘카바이드 10~20중량%, 소듐벤조에이트 1~10중량%, 펄라이트 파우더 1~10중량%, 탄산칼륨 1~10중량%의 비율로 혼합 조성을 이루게 된다.In addition, it is preferable that the bottom of the protective cover 10 be coated with a thin film of a protective layer 10' as shown in FIG. 2 to prevent sticking due to direct contact with the bead protective cushion 70. At this time, the protective layer (10') is 20 to 40% by weight of urethane resin, 10 to 30% by weight of glass wool, 10 to 30% by weight of polyolefin, 10 to 20% by weight of silicon carbide, 1 to 10% by weight of sodium benzoate, and perlite powder. It is mixed at a ratio of 1 to 10% by weight and 1 to 10% by weight of potassium carbonate.

이와 같은 구성을 이루는 본 발명 보호구조체의 설치에 따른 작용효과를 살펴보기로 한다.Let's look at the effects of installing the protective structure of the present invention configured as described above.

본 발명에서의 보호구조체인 보호커버(10)는 도 12에서 나타내어지는 바와 같이 전기 자동차의 저부에 장착된 배터리 본체(20)의 외부노출 방지 및 보호 기능을 위해 조립 설치가 이루어지게 된다.The protective cover 10, which is a protective structure in the present invention, is assembled and installed to prevent external exposure and protect the battery body 20 mounted on the bottom of the electric vehicle, as shown in FIG. 12.

즉, 보호커버(10) 조립 작업시는 차량 후면부터 각각의 개별 커버체(11,12,13) 장착을 진행하게 되는데, 각 커버체 당 고정볼트는 좌우 2개씩 4개가 사용되며, 이러한 장착 작업시 배터리 본체(20)를 감싸는 알루미늄 보호판(30)에 피스홀을 내어 조립작업이 이루어지게 된다.In other words, when assembling the protective cover (10), each individual cover body (11, 12, and 13) is installed from the rear of the vehicle. Four fixing bolts, two on each side, are used for each cover body, and this installation work Assembly work is performed by making a piece hole in the aluminum protection plate (30) surrounding the battery body (20).

이때, 보호커버(10) 내부에는 볼트 보호쿠션(50) 및 비드 보호쿠션(70)을 구성하여 볼트머리(40)와 비드(60)의 보호가 이루어지게 되며, 6개의 커버체(11,12,13)의 순차적인 조립을 통해 보호커버(10)의 장착 작업이 완료되어지게 된다.At this time, the bolt head (40) and bead (60) are protected by forming a bolt protection cushion (50) and a bead protection cushion (70) inside the protective cover (10), and six cover bodies (11, 12) The installation work of the protective cover 10 is completed through the sequential assembly of , 13).

이와 같이 장착된 본 발명의 배터리 보호커버(10)는, 전기 자동차의 주행과정에서 발생되는 외부충격으로부터 배터리를 보호하여 배터리 손상 및 파손 발생을 방지하는 효과를 나타낸다.The battery protection cover 10 of the present invention mounted in this way has the effect of preventing battery damage and damage by protecting the battery from external shocks generated during the driving process of the electric vehicle.

특히, 보호커버(10)와 배터리 본체(20) 상이에는 볼트 보호쿠션(50) 및 비드 보호쿠션(70)이 각각 내장 구비됨으로써, 완충 기능과 함께 볼트머리(40) 및 비드(60)의 보호 기능이 강화될 수 있게 된다.In particular, a bolt protection cushion (50) and a bead protection cushion (70) are provided respectively between the protective cover (10) and the battery body (20), thereby protecting the bolt head (40) and bead (60) along with a buffering function. Functions can be strengthened.

또한, 보호커버(10)의 저면에는 보호층(10')이 코팅 형성되어 있기 때문에 비드 보호쿠션(70)과 장시간 접촉과정에서 열화에 따른 비드 보호쿠션(70)이 눌어붙는 고착현상이 방지될 수 있게 된다. 특히, 보호층(10')에는 글라스울 및 폴리올레핀 성분이 혼합되어 있기 때문에 비드 보호쿠션(70)과의 마찰력을 저감시킬 수 있게 되고, 실리콘카바이드는 보호층(10')의 점도 조절 기능을 수행하며, 소듐벤조에이트는 우레탄수지의 활성화를 통한 탄력성을 유지시킬 수 있게 된다. 또한, 추가 첨가된 펄라이트 파우더 및 탄산칼륨은 각각 보호층(10')의 내구성을 강화하여 외부 충격으로 인한 크랙 발생을 방지함과 함께 내열성을 향상시키는 진보된 작용효과를 나타내게 된다.In addition, since the protective layer 10' is coated on the bottom of the protective cover 10, the sticking phenomenon of the bead protective cushion 70 due to deterioration during long-term contact with the bead protective cushion 70 can be prevented. It becomes possible. In particular, since the protective layer 10' contains a mixture of glass wool and polyolefin components, friction with the bead protection cushion 70 can be reduced, and silicon carbide performs the function of controlling the viscosity of the protective layer 10'. Sodium benzoate can maintain elasticity through activation of urethane resin. In addition, the additionally added perlite powder and potassium carbonate each strengthen the durability of the protective layer 10', preventing cracks from occurring due to external impact and exhibiting advanced effects of improving heat resistance.

한편, 도 8 내지 도 11은 본 발명의 다른 실시 예에 따른 3분할형 보호커버(10) 구조를 나타낸 것으로, 개별 커버체(11,12,13)가 6분할형에 비해 증대된 크기를 이루는 것을 확인할 수 있다.Meanwhile, Figures 8 to 11 show the structure of a three-part protective cover 10 according to another embodiment of the present invention, in which the individual cover bodies 11, 12, and 13 have an increased size compared to the six-part type. You can check that.

그리고, 상기에서 본 발명의 특정한 실시 예가 설명 및 도시되었지만 본 발명의 배터리 보호커버 구조가 당업자에 의해 다양하게 변형되어 실시될 수 있음은 자명한 일이다. In addition, although specific embodiments of the present invention have been described and shown above, it is obvious that the battery protection cover structure of the present invention can be implemented in various modifications by those skilled in the art.

예를 들면, 보호커버의 형상 및 모양은 필요에 따라 도 13 내지 도 16에서와 같은 형태로 제작이 이루어질 수 있게 된다.For example, the shape and shape of the protective cover can be manufactured as shown in FIGS. 13 to 16 as needed.

또한, 배터리 보호파이프 또한 도 17 및 도 18에서와 같은 형상을 이룰 수 있게된다.Additionally, the battery protection pipe can also have the same shape as shown in FIGS. 17 and 18.

따라서 이와 같은 변형된 실시 예들은 본 발명의 기술적 사상이나 범위로부터 개별적으로 이해되어져서는 안되며, 이와 같은 변형된 실시 예들은 본 발명의 첨부된 특허청구범위 내에 포함된다 해야 할 것이다.Therefore, such modified embodiments should not be understood individually from the technical spirit or scope of the present invention, and such modified embodiments should be included within the scope of the appended claims of the present invention.
