배터리케이스의 장착 구조와 이를 포함하는 접이식 전기자전거{Mounting structure of battery case and foldable electric bicycle including thereof}Mounting structure of battery case and foldable electric bicycle including thereof

본 발명은 배터리케이스의 장착 구조와 이를 포함하는 접이식 전기자전거에 관한 것으로, 더욱 상세하게는 접이식 전기자전거의 페달링이나 접는 동작시 간섭을 최소화하고 외관을 향상시킬 수 있을 뿐 아니라 배터리의 교체도 용이하도록 한 배터리케이스의 장착 구조와 이를 포함하는 접이식 전기자전거에 관한 것이다.The present invention relates to a mounting structure of a battery case and a foldable electric bicycle including the same, and more particularly, to minimize interference and improve appearance during pedaling or folding operation of the foldable electric bicycle, as well as to facilitate battery replacement. It relates to a mounting structure of a battery case and a foldable electric bicycle including the same.

전기자전거는 기존의 무동력 자전거와 달리 필요시 전기를 이용하여 동력을 발생시킬 수 있는 자전거로서, 사용자가 전기모터의 도움을 받아 운행이 가능한 편의성으로 인해 최근 수요가 급증하고 있으며, 특히, 앞바퀴나 뒷바퀴를 접을 수 있는 접이식 전기자전거의 경우 지하철, 차량 등의 여러 교통수단과 연계하여 이용할 수 있어 더욱 각광받고 있다.Electric bicycles, unlike conventional non-powered bicycles, are bicycles that can generate power by using electricity when necessary. Due to the convenience that users can operate with the help of electric motors, demand is increasing rapidly in recent years. In particular, the front wheel or rear wheel Folding electric bicycles that can be folded are in the spotlight because they can be used in conjunction with various transportation means such as subways and vehicles.

이러한 전기자전거는 전기를 이용하여 동력을 발생시키기 때문에 전원을 공급할 수 있는 배터리가 필수적으로 탑재되어야 한다. 배터리는 배터리케이스에 수납되어 자전거에 장착되는데, 일반 전기자전거의 경우 크기가 크고 설치공간이 비교적 여유로워 배터리케이스를 장착하는 데 별다른 제약이 없으나, 접이식 전기자전거의 경우에는 휴대성을 위해 가볍고 작게 제작될 뿐 아니라 자전거를 접을 때 다른 부속품과 간섭이 없어야 하기 때문에 일반형 전기자전거 대비 많은 제약이 따를 수 밖에 없다.Since such an electric bicycle generates power by using electricity, a battery capable of supplying power must be installed. Batteries are stored in the battery case and mounted on the bicycle.In the case of a general electric bicycle, the size of the electric bicycle is large and the installation space is relatively large, so there is no restriction on installing the battery case, but in the case of a foldable electric bicycle, it is made light and small for portability. In addition, when the bicycle is folded, there must be no interference with other accessories, so there are many restrictions compared to general electric bicycles.

예컨대, 종래에는 도 1에 도시된 바와 같이 접이식 전기자전거(10)의 메인프레임(11) 위에 배터리케이스(12)가 벨크로, 벨트 등의 고정수단으로 고정됨으로써 페달링이나 자전거를 접을 때 간섭이 발생하고, 고정수단의 고정력이 약해 자전거 운행시 발생하는 진동에 의해 배터리케이스(12)가 이탈되기 쉬우며, 자전거의 전체적인 외관도 해치는 문제점이 있었다.For example, conventionally, as shown in FIG. 1, the battery case 12 is fixed on the main frame 11 of the foldable electric bicycle 10 with a fixing means such as Velcro or a belt, so that interference occurs when pedaling or folding the bicycle. , Since the fixing force of the fixing means is weak, the battery case 12 is easily separated by vibrations generated during bicycle operation, and there is a problem that the overall appearance of the bicycle is also damaged.

본 발명은 전술한 종래기술의 문제점을 해결하기 위해 안출된 것으로, 페달링이나 접는 동작시 간섭을 최소화할 수 있고, 고정력과 외관이 우수할 뿐 아니라 탈부착도 용이하도록 한 배터리케이스의 장착 구조를 제공하는 데 목적이 있다.The present invention was conceived to solve the problems of the prior art described above, and provides a battery case mounting structure that can minimize interference during pedaling or folding operation, has excellent fixing power and appearance, as well as easy attachment and detachment.

배터리케이스(120)를 차체에 고정하기 위한 고정수단(130A)(130B)은 도 4에 도시된 바와 같이 끼움부(131)와 지지부(132)를 포함한다.The fixing means 130A and 130B for fixing the battery case 120 to the vehicle body include a fitting part 131 and a support part 132 as shown in FIG. 4.

끼움부(131)는 앞서 설명한 배터리케이스(120)의 요홈(122a)(122b)(123a)에 끼워져 걸릴 수 있는 형태를 가지며, 끼워진 상태에서 볼트(133)와 같은 체결구를 이용하여 배터리케이스(120)에 고정된다.The fitting part 131 has a shape that can be fitted and caught in the recesses 122a, 122b, 123a of the battery case 120 described above, and in the inserted state, the battery case ( 120).

지지부(132)는 끼움부(131)의 반대편에 형성되어 메인프레임(111), 싯포스트(112), 보강프레임(113) 중 어느 하나와 밀착된다. 이를 통해 배터리케이스(120)는 삼각형 공간(S) 내에 일정한 간격, 즉, 지지부(132)의 두께만큼 이격된 상태로 고정될 수 있다. 다만, 본 실시예의 경우 제1장착부(121)에는 요홈이 형성되어 있지 않아 고정수단으로 고정되지 않는데, 이러한 제1장착부(121)는 삼각형 공간(S) 내에서 이격되지 않고 메인프레임(111)에 접촉, 지지될 수 있다.The support part 132 is formed on the opposite side of the fitting part 131 and is in close contact with any one of the main frame 111, the seat post 112, and the reinforcing frame 113. Through this, the battery case 120 may be fixed in a state that is spaced apart by a predetermined interval, that is, the thickness of the support part 132 in the triangular space S. However, in the case of the present embodiment, the first mounting portion 121 is not fixed with a fixing means because the groove is not formed, such a first mounting portion 121 is not spaced apart within the triangular space (S), but in the main frame 111 Contact, can be supported.

지지부(132) 중에서 메인프레임(111), 싯포스트(112), 보강프레임(113)과 밀착되는 면은 메인프레임(111), 싯포스트(112), 보강프레임(113)의 표면에 대응되는 형상을 가지는 것이 바람직하다. 예컨대, 보강프레임(113)의 표면이 라운드진 경우에는 지지부(132)가 이에 대응하도록 오목하게 만곡된 면(132a)을 포함하여 서로 밀착될 수 있도록 한다.Among the supporting parts 132, the surfaces in close contact with the main frame 111, the seat post 112, and the reinforcing frame 113 have a shape corresponding to the surface of the main frame 111, the seat post 112, and the reinforcing frame 113 It is preferable to have. For example, when the surface of the reinforcing frame 113 is rounded, the support portion 132 includes a concave curved surface 132a to correspond thereto so that the support portion 132 may be in close contact with each other.

이상에서 설명한 고정수단(130A)(130B)은 일체로 형성되는 것도 가능하나 조립의 편의를 위해 본 실시예와 같이 2개로 구성되는 것이 바람직하다. 고정수단(130A)(130B)을 이용한 배터리케이스(120)의 설치 방법은 다음과 같다.The fixing means (130A) (130B) described above may be formed integrally, but it is preferable to be composed of two as in this embodiment for convenience of assembly. Installation method of the battery case 120 using the fixing means (130A) (130B) is as follows.

먼저, 삼각형 공간(S)에 배터리케이스(120)를 수용시킨 상태에서 하나의 고정수단(130A)을 요홈(123a)의 일측에 끼워 볼트(133)로 고정한다. 이 경우, 고정수단(130A)을 배터리케이스(120)에 볼트(133)로 먼저 고정한 후 배터리케이스(120)를 삼각형 공간(S)에 수용시키는 것도 가능하다. 이후, 나머지 고정수단(130A)으로 배터리케이스(120)의 타측을 동일하게 고정하면 배터리케이스(120)가 쐐기 방식으로 고정되어 우수한 고정력을 확보할 수 있다.First, in a state in which the battery case 120 is accommodated in the triangular space (S), one fixing means (130A) is inserted into one side of the groove (123a) and fixed with a bolt (133). In this case, it is possible to first fix the fixing means 130A to the battery case 120 with a bolt 133 and then accommodate the battery case 120 in the triangular space S. Thereafter, when the other side of the battery case 120 is equally fixed with the remaining fixing means 130A, the battery case 120 is fixed in a wedge manner, thereby securing an excellent fixing force.

한편, 상술한 방법으로 배터리케이스(120)를 고정하면 우수한 고정력을 확보할 수 있기는 하나, 접이식 전기자전거(110)의 사용 과정에서 차체에 진동이나 충격이 인가될 경우 진동과 충격이 배터리케이스(120)에 그대로 전달되어 배터리에 손상을 가하거나 메인프레임(111) 등의 표면이 벗겨질 수 있다. 따라서 메인프레임(111) 등과 접지되는 지지부(132), 특히, 만곡면(132a)에는 고무와 같은 탄성부재(134)가 부착되는 것이 바람직하다. 이처럼 만곡면(132a)에 탄성부재(134)가 부착되면 메인프레임(111) 등을 통해 전달되는 충격이나 진동이 탄성부재(134)에 의해 흡수, 분산됨으로써 배터리케이스(120)에 가해지는 손상을 최소화하여 배터리를 안전하게 보호할 수 있다.On the other hand, if the battery case 120 is fixed in the above-described manner, excellent fixing power can be secured, but when vibration or shock is applied to the vehicle body during the use of the foldable electric bicycle 110, the vibration and shock may be applied to the battery case ( 120) may damage the battery or the surface of the main frame 111 may be peeled off. Therefore, it is preferable that an elastic member 134 such as rubber is attached to the support 132 grounded with the main frame 111, and in particular, the curved surface 132a. When the elastic member 134 is attached to the curved surface 132a in this way, the shock or vibration transmitted through the main frame 111 is absorbed and dispersed by the elastic member 134, thereby preventing damage to the battery case 120. By minimizing it, the battery can be safely protected.

본 발명의 접이식 전기자전거(110)의 경우 이상에서 설명한 배터리케이스의 장착 구조가 적용되고, 이와 동시에 배터리케이스(120)와 연결된 전기선이 자전거의 접이 동작에 간섭되거나 자전거를 반복적으로 접고 펼칠 때 파손되지 않도록 배터리케이스(120)의 하방으로 지나가도록 배선되며, 브레이크 라인, 기어 변속 라인 등이 자전거 프레임을 중심으로 후방 브레이크와 변속 허브에 연결된다.In the case of the folding electric bicycle 110 of the present invention, the mounting structure of the battery case described above is applied, and at the same time, the electric wire connected to the battery case 120 interferes with the folding operation of the bicycle or is not damaged when the bicycle is repeatedly folded and unfolded. It is wired so as to pass downward of the battery case 120 so that the brake line, gear shift line, etc. are connected to the rear brake and shift hub around the bicycle frame.
