이하 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다. 그리고 본 발명을 설명함에 있어서, 관련된 공지기능 혹은 구성에 대한 구체적인 설명이 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 경우 그 상세한 설명을 생략한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Further, in describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

본 발명의 배터리 효율이 개선된 전동 오토바이는 도 1에 도시한 바와 같이 조향용 전륜(110) 및 구동용 후륜(120)이 설치되는 프레임(130)의 안장(131)과 핸들(132)이 설치되는 본체부(100)와, 상기 본체부(100)의 조향용 전륜(110) 및 구동용 후륜(120)에 각각 설치되어 전기를 생성하는 발전부(200)와, 상기 발전부(200)의 생성된 전기가 저장되도록 리튬이온전지로 적용되는 축전부(300)와, 상기 축전부(300)의 전기를 제공받아 구동용 후륜(120)을 회전시키는 구동부(400);로 이루어진다.In the electric motorcycle with improved battery efficiency of the present invention, the saddle 131 and the handle 132 of the frame 130 on which the front wheel 110 for steering and the rear wheel 120 for driving are installed are installed as shown in FIG. The main body portion 100, the power generation unit 200 for generating electricity by being installed on each of the steering front wheel 110 and the driving rear wheel 120 of the main body 100, and the power generation unit 200 It consists of a power storage unit 300 applied as a lithium-ion battery to store generated electricity, and a driving unit 400 that receives electricity from the power storage unit 300 and rotates the driving rear wheel 120.

그리고 상기 축전부(300)는 메인배터리(310)와 보조배터리(320)로 구성되고, 상기 메인배터리(310)의 전원 잔량을 체크하는 잔량체크부(500)와, 상기 메인배터리(310)의 전원 잔량이 10%에 도달하였을 때 보조배터리(320)로 전환되도록 제어하는 전원공급 제어부(600);를 포함하여 이루어지는 것을 특징으로 한다.And the power storage unit 300 is composed of a main battery 310 and an auxiliary battery 320, the remaining amount check unit 500 for checking the remaining amount of power of the main battery 310, and the main battery 310 It characterized in that it comprises a; power supply control unit 600 for controlling to be switched to the auxiliary battery 320 when the remaining amount of power reaches 10%.

상기 본체부(100)는 전동 오토바이의 외형적인 구성을 나타내는 것으로서, 조향용 전륜(110)을 통해 오토바이의 이동방향을 제어하고, 구동용 후륜(120)을 통해 오토바이의 추진력을 발생하게 된다. 그리고 프레임(130)에는 안장(131)과 핸들(132)이 설치되어 있다.The main body 100 represents an external configuration of an electric motorcycle, and controls the moving direction of the motorcycle through the front wheels 110 for steering, and generates the propulsion force of the motorcycle through the rear wheels 120 for driving. In addition, a saddle 131 and a handle 132 are installed in the frame 130.

상기 발전부(200)는 본체부(100)의 조향용 전륜(110)과 구동용 후륜(120)에 각각 설치되는 것으로서, 오토바이의 바퀴에서 발생되는 회전력을 이용하여 내부에 설치된 코일과 자석이 전자기 유도방식으로 발전하게 되는 것이다. 그리고 상기 발전부(200)는 항시 전기를 생성하는 것보다, 축전부(300)의 전기를 통해 구동부(400)를 작동시키지 않은 상태 즉, 내리막길 주행중이거나 브레이크를 통해 제동이 이루어질 때 발전되는 것이 바람직하다. The power generation unit 200 is installed on each of the steering front wheel 110 and the driving rear wheel 120 of the main body 100, and a coil and a magnet installed therein using the rotational force generated from the wheel of the motorcycle are electromagnetic It will develop in an induction method. And, rather than always generating electricity, the power generation unit 200 is generated when the driving unit 400 is not operated through electricity from the power storage unit 300, that is, when driving downhill or when braking is performed through the brake. desirable.

본 발명의 축전부(300)는 메인배터리(310)와 보조배터리(320)로 구성되며, 발전부(200)를 통해 주행중에 충전이 이루어질 수도 있고, 지정된 장소에서 충전 케이블(150)을 통해 220V와 같은 상용전기가 공급될 수 있도록 한다.The power storage unit 300 of the present invention is composed of a main battery 310 and an auxiliary battery 320, and may be charged while driving through the power generation unit 200, or 220V through the charging cable 150 at a designated place. It allows the same commercial electricity to be supplied.

그리고 본 발명의 축전부(300)는 리튬이온전지로 적용된다. 리튬이온전지는 종래의 니켈-카드뮴전지에 비해 무게가 가볍고, 크기에 비해 많은 양의 전기에너지를 저장할 수 있고, 자가방전율이 낮으며, 중금속을 사용하지 않아 친환경적인 이점을 갖는다. 반면, 메모리효과(memory effect)가 존재하지 않으며 완전 방전시 배터리의 수명이 단축되며, 외부 온도에 의해 배터리가 민감한 단점을 갖는다.And the power storage unit 300 of the present invention is applied as a lithium ion battery. Lithium-ion batteries are lighter in weight than conventional nickel-cadmium batteries, can store a large amount of electrical energy compared to their size, have a low self-discharge rate, and are eco-friendly because they do not use heavy metals. On the other hand, there is no memory effect, and when completely discharged, the life of the battery is shortened, and the battery is sensitive to external temperature.

따라서, 본 발명은 축전부(300)가 완전 방전되어 수명이 단축되는 것을 방지하기 위해, 잔량체크부(500)를 통해 메인배터리(310)의 전원 잔량을 실시간으로 체크하여, 메인배터리(310)의 전원 잔량이 줄어들면서 10%로 감소하였을 경우, 전원공급 제어부(600)에서 이를 감지하여 공급전원을 메인배터리(310)에서 보조배터리(320)로 전환되도록 한다.Accordingly, the present invention checks the power remaining amount of the main battery 310 in real time through the remaining amount check unit 500 in order to prevent the power storage unit 300 from being completely discharged and shortening the lifespan, and the main battery 310 When the remaining amount of power is reduced to 10%, the power supply control unit 600 detects this and converts the supplied power from the main battery 310 to the auxiliary battery 320.

상기 보조배터리(320)는 메인배터리(310)가 완전히 방전되는 것을 막기 위한 보조수단에 해당되기 때문에, 메인배터리(310)는 보조배터리(320)에 비해 더 많은 전기 저장용량을 갖도록 한다. 즉, 메인배터리(310)는 고가의 고용량 배터리로 적용하고 배터리 방전을 막아 장기간 사용할 수 있도록 하되, 보조배터리(320)는 저용량 저가의 배터리로 적용함으로써, 비교적 고가의 메인배터리(310)보다 저가의 보조배터리(320)를 교체를 유도하여 배터리 사용에 따른 유지비용을 최소화하고자 하는 것이다.Since the auxiliary battery 320 corresponds to an auxiliary means for preventing the main battery 310 from being completely discharged, the main battery 310 has a larger electric storage capacity than the auxiliary battery 320. That is, the main battery 310 is applied as an expensive, high-capacity battery and can be used for a long time by preventing battery discharge, but the auxiliary battery 320 is applied as a low-capacity and inexpensive battery, so that it is cheaper than the relatively expensive main battery 310. To induce replacement of the auxiliary battery 320, it is intended to minimize maintenance costs due to use of the battery.

그리고 본 발명의 본체부(100) 핸들(132)에는 축전부(300)의 전원 잔량, 메인배터리(310) 및 보조배터리(320)의 사용현황, 충전상황이 표시되도록 하는 정보패널(140);을 더 포함하여 다양한 정보를 사용자가 직접 확인할 수 있도록 하는 것이 좋다.In addition, the main body 100, the handle 132 of the present invention, the power remaining amount of the power storage unit 300, the status of use of the main battery 310 and the auxiliary battery 320, the information panel 140 to display the charging status; It is better to allow the user to directly check various information including more.

아울러, 본 발명은 충전 케이블(150)을 통한 충전은 메인배터리(310)와 보조배터리(320)가 동시에 충전되도록 하되, 발전부(200)에서 충전되는 전기가 메인배터리(310) 또는 보조배터리(320) 중에서 선택되도록 제어하는 충전선택 제어부(700);가 더 구비될 수 있다. 즉, 발전부(200)에서 충전되는 전기에너지만으로 메인배터리(310)와 보조배터리(320)를 동시에 충전하는데에 한계가 존재하기 때문에, 메인배터리(310)의 전원잔량이 20%이하일 경우 메인배터리(310)를 우선적으로 충전함으로써 메인배터리(310)의 완전방전을 방지하고, 일정 %의 충전상태를 유지함으로써 메인배터리(310)의 수명을 연장할 수 있다. In addition, in the present invention, charging through the charging cable 150 allows the main battery 310 and the auxiliary battery 320 to be simultaneously charged, but the electricity charged in the power generation unit 200 is the main battery 310 or the auxiliary battery ( A charge selection control unit 700 for controlling to be selected from among 320) may be further provided. That is, since there is a limit to simultaneously charging the main battery 310 and the auxiliary battery 320 only with the electric energy charged in the power generation unit 200, the main battery 310 when the remaining power of the main battery 310 is less than 20% By preferentially charging the main battery 310, complete discharge of the main battery 310 is prevented, and the life of the main battery 310 may be extended by maintaining a charged state of a certain percentage.

상기 충전선택 제어부(700)의 충전 방법에 대해 좀더 구체적으로 설명하자면,상기 메인배터리(310)의 충전은 전원 잔량이 20%이하일 경우 80%에 도달할 때까지 우선적으로 충전한 다음, 보조배터리(320)의 충전을 진행하게 된다. 만약, 메인배터리(310)의 전원 잔량이 80% 이상일 경우 보조배터리(320)의 충전을 우선적으로 하게 되며, 메인배터리(310)와 보조배터리(320) 모두 80% 이상의 전원 잔량일 경우 메인배터리(310)->보조배터리(320) 순서로 완전 충전하게 되는 것이다. 그러나 내리막길이 장시간 지속되는 것이 아니라면 발전부(200)를 통해 메인배터리(310)와 보조배터리(320)의 전원 잔량이 100%를 유지하는 것은 어렵다고 할 수 있다.To explain the charging method of the charge selection control unit 700 in more detail, the charging of the main battery 310 is preferentially charged until it reaches 80% when the remaining power is less than 20%, and then the auxiliary battery ( 320) is charged. If the power remaining of the main battery 310 is 80% or more, charging of the auxiliary battery 320 is given priority, and when both the main battery 310 and the auxiliary battery 320 have 80% or more power remaining, the main battery ( It will be fully charged in the order of 310)-> auxiliary battery (320). However, it can be said that it is difficult to maintain 100% of the power remaining of the main battery 310 and the auxiliary battery 320 through the power generation unit 200 unless the downhill road lasts for a long time.

앞서 설명한 바와 같이 본 발명의 축전부(300)는 리튬이온전지로 적용되기 때문에, 외부의 온도에 민감한 단점을 갖고 있다. 즉, 외부의 온도가 너무 낮은 경우 배터리의 일시적인 성능저하가 발생되고, 온도가 너무 높을 경우 배터리의 노화현상이 발생하게 되어 수명이 단축되게 된다.As described above, since the power storage unit 300 of the present invention is applied as a lithium ion battery, it has a disadvantage that is sensitive to external temperature. That is, when the external temperature is too low, a temporary deterioration of the battery performance occurs, and when the temperature is too high, an aging phenomenon of the battery occurs and the lifespan is shortened.

따라서 본 발명의 축전부(300)는 도 3에 도시한 바와 같이 보호케이스(800)를 구성하여 내부에 메인배터리(310)와 보조배터리(320)를 설치하게 된다. 상기 보호케이스(800)는 겨울철을 제외한 나머지 계절에는 주행과정에서 내부로 유입되는 바람에 의해 메인배터리(310)와 보조배터리(320)의 열을 식힐 수 있도록 하면서, 겨울철에는 외부의 공기가 유입되지 않도록 차단되는 구조로 되어 있다.Accordingly, the power storage unit 300 of the present invention constitutes the protective case 800 as shown in FIG. 3 to install the main battery 310 and the auxiliary battery 320 therein. The protective case 800 cools the heat of the main battery 310 and the auxiliary battery 320 by wind flowing into the inside during the driving process in the rest of the seasons except in winter, while outside air does not enter in winter. It has a structure that is blocked to prevent it.

상기 보호케이스(800)의 구성은 사각형의 함체로 이루어져 전면부(810a), 양측면부(810b), 후면부(810c)에 각각 제1통공부(811)가 형성되어 있는 케이스본체(810)와, 상기 케이스본체(810)의 개방된 상부에 결합되는 덮개(830)와, 상기 케이스본체(810)의 내측에 바닥면을 제외한 나머지면에 밀착되도록 구성되되, 제1통공부(811)의 위치와 대응되는 위치에 제2통공부(821)가 형성되고, 상하로 움직일 수 있도록 하여 제1통공부(811)를 개폐하는 개폐부재(820);로 이루어져 있다.The configuration of the protective case 800 is a case body 810 in which a first through hole 811 is formed in each of the front portion 810a, both side portions 810b, and the rear portion 810c made of a rectangular housing, The cover 830 coupled to the open upper portion of the case body 810 and the case body 810 is configured to be in close contact with the other surface except the bottom surface, and the position of the first through hole 811 A second through hole 821 is formed at a corresponding position, and an opening/closing member 820 for opening and closing the first through hole 811 by allowing it to move up and down.

상기 케이스본체(810)에는 제1통공부(811)가 전면부(810a), 양측면부(810b), 후면부(810c)에 각각 형성되어 있어서, 전면부(810a)와 양측면부(810b)의 제1통공부(811)로 유입되는 공기가 메인배터리(310)와 보조배터리(320)를 냉각시킨 다음 후면부(810c)의 제1통공부(811)로 배출되게 되는 것이다. 이때 전면부(810a)와 후면부(810c)에 형성된 제1통공부(811)는 주행방향에 맞게 형성되어 있기 때문에 공기의 유입 및 배출이 용이하게 이루어지지만, 양측면부(810b)에 형성된 제1통공부(811)의 경우 주행과정에서 외부의 공기유입이 원활하지 않다. In the case body 810, a first through hole 811 is formed in the front portion 810a, both side portions 810b, and the rear portion 810c, respectively, so that the first through-hole portion 811 is formed in the front portion 810a and the both side portions 810b. The air flowing into the first through hole 811 cools the main battery 310 and the auxiliary battery 320 and then is discharged to the first through hole 811 of the rear part 810c. At this time, since the first through-holes 811 formed in the front portion 810a and the rear portion 810c are formed in accordance with the driving direction, air intake and discharge are facilitated, but the first cylinder formed on both side surfaces 810b In the case of study (811), outside air inflow is not smooth during the driving process.

따라서, 상기 케이스본체(810)의 양측면부(810b)에는 도 3에 도시한 바와 같이 제1통공부(811)로 외부의 공기가 안내될 수 있도록, 날개부(812)가 돌출형성되는 것이 바람직하다. 상기 날개부(812)는 주행과정에서 날개부(812)에 부딪힌 공기가 날개부(812)를 따라 제1통공부(811)로 유입되기 위한 것으로서 도면과 같이 대각선 방향으로 형성되는 것이 좋다.Therefore, it is preferable that the wing portions 812 are protruded on both side surfaces 810b of the case body 810 so that external air can be guided to the first through hole 811 as shown in FIG. 3. Do. The wing portion 812 is for introducing the air hitting the wing portion 812 during the driving process into the first through hole portion 811 along the wing portion 812 and is preferably formed in a diagonal direction as shown in the drawing.

그리고 상기 케이스본체(810)에는 수직으로 장공부(813)가 형성되고, 상기 장공부(813)를 따라 개폐부재(820)가 상하로 움직일 수 있도록 개폐부재(820) 외측으로 돌출 형성된 조절레버(822)가 장공부(813)를 관통하는 형태로 구성된다. 상기 케이스본체(810)에는 개폐부재(820)가 상하로 움직일 수 있도록 한 여유공간이 마련되어 있어야 하는데, 도면에 도시한 바와 같이 덮개(830)를 케이스본체(810)의 상부보다 더 높게 구성하여 개폐부재(820)가 상승할 수 있도록 한 공간을 형성하거나, 개폐부재(820)의 높이를 작게 하여 개폐부재(820)가 상승할 수 있도록 한다.And the case body 810 has a long hole portion 813 is formed vertically, along the long hole portion 813, so that the opening and closing member 820 can move up and down, an adjustment lever protruding outside the opening member 820 ( 822 is configured to pass through the long hole 813. The case body 810 must be provided with a free space so that the opening and closing member 820 can move up and down. As shown in the drawing, the cover 830 is configured higher than the upper portion of the case body 810 to open and close. A space is formed so that the member 820 can rise, or the height of the opening/closing member 820 is reduced so that the opening/closing member 820 can rise.

상기 개폐부재(820)는 겨울철을 제외한 나머지 계절에는 도 4에 도시한 바와 같이 개폐부재(820)를 내려서, 개폐부재(820)의 제2통공부(821)와 케이스본체(810)의 제1통공부(811)의 위치가 서로 일치하도록 구성하여, 주행중 공기의 유입을 통해 메인배터리(310) 및 보조배터리(320)의 과열을 방지할 수 있도록 한다.The opening/closing member 820 lowers the opening/closing member 820 as shown in FIG. 4 in the rest of the seasons excluding the winter, and the second through hole 821 of the opening/closing member 820 and the first of the case body 810 The positions of the through holes 811 are configured to match each other, so that the main battery 310 and the auxiliary battery 320 can be prevented from overheating through the introduction of air during driving.

그리고 겨울철에는 도 5에 도시한 바와 같이 개폐부재(820)를 상승하여 제2통공부(821)가 형성되지 않은 면이 제1통공부(811)를 막을 수 있도록 한다. 개폐부재(820)를 상승시킬 때에는 조절레버(822)를 손으로 잡고 들어올릴 수 있도록 한다. 이때 개폐부재(820)가 상승한 상태를 유지하기 위해서는 개폐부재(820)의 상단부에는 고정홈(823)을 형성하고, 상기 개폐부재(820)의 고정홈(823)과 결합되기 위한 고정돌부(831)가 덮개(830)의 내측에 형성될 수 있다.And in winter, as shown in FIG. 5, the opening and closing member 820 is raised so that the surface on which the second through hole 821 is not formed can block the first through hole 811. When raising the opening and closing member 820, the adjustment lever 822 is held and lifted by hand. At this time, in order to maintain the raised state of the opening and closing member 820, a fixing groove 823 is formed at the upper end of the opening and closing member 820, and a fixing protrusion 831 for coupling with the fixing groove 823 of the opening and closing member 820 ) May be formed on the inside of the cover 830.
