Description

포터블 발전기{Portable generator}Portable generator

본 발명은 외부장치에 설치된 상태로 주행풍에 의해 작동하여 전력을 생산하고 생산된 전력을 배터리로 전달할 수 있는 포터블 발전기에 관한 것이다.The present invention relates to a portable generator that is installed in an external device and is capable of generating power by operating by running wind and delivering the generated power to a battery.

대체 에너지에 관한 연구가 진행되면서 최근 전기차 대한 관심이 폭증하고 있다. 전기차는 내연기관을 대신하는, 배터리와 모터를 구동원으로 사용하는 만큼, 화석연료에 의한 대기오염을 유발하지 않아 친환경적인 이동수단으로 자리매김 하고 있다. As research on alternative energy progresses, interest in electric vehicles is increasing recently. As electric vehicles use batteries and motors as driving sources instead of internal combustion engines, they do not cause air pollution caused by fossil fuels, so they have established themselves as eco-friendly means of transportation.

전기차량으로 분류되는 차량에는, 순수전기차(Pure EV)와 수소전기차(FCEV)가 포함된다. 순수전기차는 전력을 배터리로부터만 공급받는 것이며, 수소전기차는, 연료전지스택으로부터 전력을 공급받는 것이다.Vehicles classified as electric vehicles include pure electric vehicles (Pure EV) and hydrogen electric vehicles (FCEV). Pure electric vehicles receive power only from the battery, and hydrogen electric vehicles receive power from the fuel cell stack.

순수전기차의 단점은 주행거리에 제약이 많아, 말하자면, 배터리를 완전 충전한 상태에서의 최대 운행 가능거리가 짧아, 자주 충전해야 하는 것이다. 더욱이 충전에 소요되는 시간이 길어, 이를테면 불과 6시간 남짓 주행하기 위하여 4시 간 이상을 충전해야 하는 등의 불편이 있는 것이다. 그나마 배터리의 성능 저하에 따라 충전시간은 더 길어지기 마련이다.The disadvantage of a pure electric vehicle is that the driving distance is limited, so to speak, that the maximum driving distance in a fully charged state is short, so it must be charged frequently. Moreover, the time required for charging is long, for example, in order to drive for only 6 hours or more, there is inconvenience such as having to charge for 4 hours or more. However, as the performance of the battery degrades, the charging time will be longer.

수소전기차의 단점은, 수소 저장탱크와 연료전지스택 시스템의 가격이 매우 고가(高價)이며, 수소 충전소 등의 인프라가 수소전기차에 비해서도 부족하다는 것이다.The disadvantages of the hydrogen electric vehicle are that the hydrogen storage tank and the fuel cell stack system are very expensive, and the infrastructure such as a hydrogen charging station is insufficient compared to that of the hydrogen electric vehicle.

한편, 최근 출시되는 순수전기차(이하, 전기차)는, 일회 충전 당, 차량의 주행 가능 거리를 늘리기 위해, 차체를 경량화 하여 연비의 상승을 도모하고 있다. 하지만, 차체의 구조를 개선한다 하더라도 차체의 경량화는 어딘가에 한계가 있는 것이므로, 주행 가능거리를 늘리기 위한 다른 방식의 기술이 필요하다. 예컨대 배터리의 충전율을 최대한 유지시키기 위한 기술이 필요한 것이다.On the other hand, recently released pure electric vehicles (hereinafter, electric vehicles) are attempting to increase fuel efficiency by reducing the weight of the vehicle body in order to increase the distance the vehicle can travel per charge. However, even if the structure of the vehicle body is improved, the weight reduction of the vehicle body is limited somewhere, and thus another method of technology is required to increase the driving distance. For example, a technology is needed to keep the charging rate of the battery as much as possible.

이하, 본 발명에 따른 하나의 실시예를 첨부된 도면을 참조하여 보다 상세히 설명하기로 한다.Hereinafter, an embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

도 1은 본 발명의 일 실시예에 따른 포터블 발전기의 주요 구성을 설명하기 위한 측단면도이다.1 is a side cross-sectional view for explaining the main configuration of a portable generator according to an embodiment of the present invention.

기본적으로, 본 실시예에 따른 포터블 발전기(10)는, 외부장치, 예를 들어 전기차(도 6의 A)의 적절한 위치에 장착되며, 전기차(A) 주행 중의 주행풍을 받아 작동하여 전력을 생산하는 것으로서, 임펠러부(12)와 발전부(14)와 고정장치(도3 및 도 5의 40)를 갖는다.Basically, the portable generator 10 according to the present embodiment is mounted in an appropriate position of an external device, for example, an electric vehicle (Fig. 6A), and generates electric power by receiving the driving wind while driving the electric vehicle A. As a result, it has an impeller part 12, a power generation part 14, and a fixing device (40 in FIGS. 3 and 5).

도시한 바와 같이, 발전부(14)는, 상호 결합하여 내부공간(14e)을 형성하는 전방하우징(14a) 및 후방하우징(14c)과, 내부공간(14e)에 고정되는 스테이터(16)와, 스테이터(16)의 중심부에 회전 가능하도록 구비되고 외력에 의해 축회전하여 전력을 발생시키는 로터어셈블리(20)를 포함한다.As shown, the power generation unit 14 includes a front housing 14a and a rear housing 14c that are coupled to each other to form an inner space 14e, and a stator 16 fixed to the inner space 14e, It is provided to be rotatable in the center of the stator 16 and includes a rotor assembly 20 for generating electric power by axial rotation by an external force.

상기 전방하우징(14a)과 후방하우징(14c)은 서로에 대해 개방된 원통형 부재로서, 스테이터(16)와 로터어셈블리(20)를 수용한 상태로 결합하여 하나의 원통형 케이싱을 구성한다. The front housing 14a and the rear housing 14c are cylindrical members that are open to each other, and are combined with the stator 16 and the rotor assembly 20 to form one cylindrical casing.

또한 전방하우징(14a)의 도면상 저면에는 베어링홈부(14b)가 형성되며 그 내부에 베어링(27)을 수용한다. 후방하우징(14c)의 상면에도 다른 베어링(27)을 수용 고정하는 베어링홈부(14d)가 마련되어 있다. 상기 두 개의 베어링(27)은 베어링홈부(14b,14d)에 고정된 상태로 커넥팅샤프트(21)를 축회전 가능하게 지지한다.In addition, a bearing groove 14b is formed on the bottom surface of the front housing 14a and accommodates the bearing 27 therein. A bearing groove 14d for accommodating and fixing the other bearing 27 is also provided on the upper surface of the rear housing 14c. The two bearings 27 support the connecting shaft 21 to be axially rotated while being fixed to the bearing grooves 14b and 14d.

상기 스테이터(16)는 일반적인 발전기와 마찬가지로, 내부공간(14e)의 내부에 고정되며 코일(16a)이 권회되어 있는 부분으로서, 전방하우징(14a)의 내벽면에 고정된다. 후방하우징(14c)을 전방하우징(14a)으로부터 분리할 경우, 스테이터(16)는 전방하우징(14a)에 고정된 상태로 남아 있는 것이다.The stator 16, like a general generator, is fixed inside the inner space 14e and is a part in which the coil 16a is wound, and is fixed to the inner wall surface of the front housing 14a. When the rear housing 14c is separated from the front housing 14a, the stator 16 remains fixed to the front housing 14a.

상기 로터어셈블리(20)는 스테이터(16)의 중심부분에 회전 가능하도록 설치되며, 후술할 임펠러(29,45)로부터 회전력을 전달받아 축회전하여 전력이 발생하도록 하는 것으로서, 도 2에 도시한 구성을 갖는다.The rotor assembly 20 is installed to be rotatable in the central portion of the stator 16, and receives a rotational force from the impellers 29 and 45 to be described later, and rotates the axis to generate power, as shown in FIG. Has.

도 2는 도 1에 도시한 로터어셈블리(20)의 분해 사시도이다.2 is an exploded perspective view of the rotor assembly 20 shown in FIG. 1.

도 2에 도시한 바와 같이, 로터어셈블리(20)는, 커넥팅샤프트(21)와, 커넥팅샤프트(21)를 그 중심부로 통과시키는 육각로터(23)와, 육각로터(23)의 외측부에 고정되는 다수의 착탈형자석(25)으로 구성된다.As shown in FIG. 2, the rotor assembly 20 includes a connecting shaft 21, a hexagonal rotor 23 passing the connecting shaft 21 through the center thereof, and fixed to the outer side of the hexagonal rotor 23. It consists of a number of detachable magnets (25).

It serves to transmit the rotational force of the impeller (29,45) to the power generation unit (14).

또한 육각로터(23)는 그 중심축부로 커넥팅샤프트(21)를 통과시키는 육각기둥형 부재이다. 육각로터(23)는 스테이터(16)의 중심축부에서 착탈형자석(25)과 함께 축회전한다. 특히 도 2에 도시한 바와 같이 육각로터(23)의 외향면에는 6개의 고정면(23a)이 마련되어 있다. 상기 고정면(23a)은 착탈형자석(25)을 개별적으로 고정하는 평평한 고정면으로서 두 개씩의 암나사구멍(23b)을 갖는다. In addition, the hexagonal rotor 23 is a hexagonal columnar member that passes the connecting shaft 21 through its central axis.

In addition, the detachable magnet 25 serves to increase the rotational inertia of the rotor assembly 20 while being fixed to the outer surface of the hexagonal rotor 23.

아울러, 착탈형자석(25)에는 두 개씩의 관통구멍(25a)이 마련되어 있다. 관통구멍(25a)은 암나사구멍(23b)에 대응하는 것으로서 고정나사(25b)를 통과시킨다. 각 착탈형자석(25)을 고정면(23a)에 밀착시킨 상태로 고정나사(25b)를 관통구멍(25a)을 통해 암나사구멍(23b)에 결합함으로써 육각로터(23)에 대한 착탈형자석(25)의 고정이 이루어지는 것이다.In addition, the detachable magnet 25 is provided with two through holes 25a.

한편, 상기 임펠러부(12)는 임펠러케이싱(12a)과 임펠러(29)를 포함한다. 임펠러케이싱(12a)은 전방하우징(14a)의 도면상 상부에 결합하며 수용공간(12d)을 제공하는 부재로서, 제1통로(12b) 및 제2통로(12c)를 통해 외부로 개방된다. 도 1에 도시한 임펠러(29)는, 회전중심축과 같은 방향으로 들어오는 공기의 압력을 받아 축회전 하는 것이므로 말하자면 축류형이라고 할 수 있다.Meanwhile, the impeller unit 12 includes an impeller casing 12a and an impeller 29. The impeller casing 12a is a member that is coupled to the upper portion of the front housing 14a and provides an accommodation space 12d, and is opened to the outside through the first passage 12b and the second passage 12c. The impeller 29 shown in FIG. 1 is axially rotated by receiving the pressure of air coming in the same direction as the rotational center axis, so it can be said to be an axial flow type.

상기 임펠러(29)는 제1통로(12b)를 통해 화살표 a방향으로 유입한 주행풍의 압력을 받아 회전하며 커넥팅샤프트(21)를 축회전시킨다. 임펠러(29)에 운동에너지를 전달한 후의 공기는 제2통로(12c)를 통과해 화살표 b방향으로 배출된다. 발전부(14)는 임펠러(29)의 회전력을 전달받아 전력을 생산하고 생산된 전력을 출력선(17)을 통해 외부, 즉 배터리(도 6의 Z)로 인가한다.The impeller 29 rotates under the pressure of the running wind flowing in the direction of the arrow a through the first passage 12b and rotates the connecting shaft 21 axially. Air after kinetic energy is transmitted to the impeller 29 passes through the second passage 12c and is discharged in the direction of arrow b. The power generation unit 14 generates power by receiving the rotational force of the impeller 29 and applies the generated power to the outside, that is, a battery (Z in FIG. 6) through the output line 17.

참고로, 상기 출력선(17)은 가령, (상호 다른 칼라를 갖는) 1번선 내지 6번 선의 6개의 가닥으로 구현할 수 있다. 또한, 각 가닥의 전선은 다양한 조합을 통해 상호 다른 전압을 출력할 수 있다. 가령, 1번선과 2번선을 조합하여 200볼트, 1번선과 3번선을 조합하여 15볼트, 1번선과 4번선을 조합하여 200볼트, 1번선과 5번선을 조합하여 200볼트, 1번선과 6번선을 조합하여 140볼트, 2번선과 4번선을 조합하여 200볼트, 2번선과 5번선을 조합하여 100볼트, 2번선과 6번선을 조합하여 200볼트, 3번선과 4번선을 조합하여 200볼트, 3번선과 6번선을 조합하여 200볼트, 3번선과 5번선을 조합하여 250볼트, 3번선과 2번선을 조합하여 300볼트를 출력할 수 있는 것이다.For reference, the output line 17 may be implemented as 6 strands of lines 1 to 6 (having different colors). In addition, the wires of each strand may output different voltages through various combinations. For example, 200 volts by combining line 1 and line 2, 15 volts by combining line 1 and line 3, 200 volts by combining line 1 and line 4, 200 volts by combining line 1 and line 5, and line 1 and 6 140 volts by combining lines, 200 volts by combining lines 2 and 4, 100 volts by combining lines 2 and 5, 200 volts by combining lines 2 and 6, and 200 volts by combining lines 3 and 4 , 200 volts by combining line 3 and line 6, 250 volts by combining line 3 and line 5, and 300 volts by combining line 3 and line 2 are possible.

상기와 같이 다양한 전압을 출력할 수 있으므로, 전기차 각부의 전력수요처가 요구하는 적절한 전력을 공급할 수 있다.Since it is possible to output various voltages as described above, it is possible to supply appropriate power required by power demanders of each part of the electric vehicle.

한편, 상기 고정장치(40)는, 도 3에 대략적으로 도시한 바와 같이, 포터블 발전기(10)를 전기차(A)에 고정하는 역할을 하는 것으로서, 그 구성을 도 3을 통해 설명하기로 한다.Meanwhile, the fixing device 40 serves to fix the portable generator 10 to the electric vehicle A, as schematically shown in FIG. 3, and its configuration will be described with reference to FIG. 3.

도 3은 본 발명의 일 실시예에 따른 포터블 발전기(10)의 사용 방식을 설명하기 위한 도면이다.3 is a diagram for explaining a method of using the portable generator 10 according to an embodiment of the present invention.

도 3에 도시한 바와 같이, 상기 고정장치(40)는, 전자석(42)과 완충패드(41)를 포함한다. 전자석(42)은 그 내부에 배터리(미도시)가 내장된 휴대형 전자석으로서 스위치(42a)에 의해 온오프된다. 가령 스위치(42a)를 온(ON)시키면 전자석(42)이 착자되어 전기차(A)의 표면에 고정되고, 오프(OFF) 시키면 탈자되어 포터블 발전기(10)를 들어 올려 회수할 수 있는 것이다.As shown in FIG. 3, the fixing device 40 includes an electromagnet 42 and a buffer pad 41. The electromagnet 42 is a portable electromagnet in which a battery (not shown) is embedded, and is turned on and off by a switch 42a. For example, when the switch 42a is turned on, the electromagnet 42 is magnetized and fixed to the surface of the electric vehicle A, and when the switch 42a is turned off, it is demagnetized and the portable generator 10 is lifted and recovered.

아울러 상기 완충패드(41)는, 일정두께를 가지는 판상부재로서, 전자석(42)과 후방하우징(14c)의 사이에 개재된 상태로 진동을 감쇄시킨다. 이를테면, 전기차(A)의 주행중 발생하는 진동이 포터블 발전기(10)로 전달되는 것을 차단하고, 반대로 포터블 발전기(10)에서 발생하는 진동이 전기차(A)로 전달되는 것을 방지하는 것이다. 완충패드(41)로서 고무나 실리콘을 사용할 수 있다.In addition, the buffer pad 41 is a plate-shaped member having a predetermined thickness and attenuates vibration while being interposed between the electromagnet 42 and the rear housing 14c. For example, it blocks vibration generated during driving of the electric vehicle A from being transmitted to the portable generator 10, and conversely, prevents the vibration generated in the portable generator 10 from being transmitted to the electric vehicle A. Rubber or silicone may be used as the buffer pad 41.

아울러, 도 3에 도시한 바와 같이, 포터블 발전기(10)의 제1통로(12b)가 전기차(A)의 주행방향 P를 향하고 있다. 즉 포터블 발전기(10)가 눕힌 상태로 세팅되는 것이다. 전기차의 주행에 따라 제1통로(12b)로 유입한 주행풍은 임펠러(29)를 회전시킨 후 제2통로(12c)를 통해 배출된다.In addition, as shown in FIG. 3, the first passage 12b of the portable generator 10 faces the driving direction P of the electric vehicle A. That is, the portable generator 10 is set in a lying state. The running wind flowing into the first passage 12b according to the driving of the electric vehicle is discharged through the second passage 12c after rotating the impeller 29.

도 4는 본 발명의 일 실시예에 따른 포터블 발전기(10)의 다른 예를 도시한 측단면도이다.4 is a side cross-sectional view showing another example of the portable generator 10 according to an embodiment of the present invention.

상기한 도면부호와 동일한 도면부호는 동일한 기능의 동일한 부재를 가리킨다.The same reference numerals as the above-described reference numerals denote the same members having the same function.

도 4에 도시한 임펠러(45)는 도 1에 도시한 임펠러(29)와 다른 형태를 갖는다. 도 4의 임펠러(45)는 제2통로(12c)를 통해 화살표 c방향으로 유입한 주행풍에 의해 압력을 전달받는 형식의 것이다. 화살표 c방향으로 유입한 주행풍은, 임펠러케이싱(12a)을 가로지르며 임펠러(45)를 회전시킨 후 반대편으로 화살표 d방향으로 배출된다. 임펠러(45)의 회전에 의해 발전부(14)가 전력을 생산함은 위에 설명한 바와 같다.The impeller 45 shown in FIG. 4 has a different shape from the impeller 29 shown in FIG. 1. The impeller 45 of FIG. 4 is of a type receiving pressure by the running wind flowing in the direction of the arrow c through the second passage 12c. The running wind flowing in the direction of the arrow c crosses the impeller casing 12a, rotates the impeller 45, and is discharged to the opposite side in the direction of the arrow d. It is as described above that the power generation unit 14 generates power by the rotation of the impeller 45.

도 5는 도 4에 도시한 포터블 발전기(10)의 사용 방식을 나타내 보인 도면이다.5 is a view showing a method of using the portable generator 10 shown in FIG. 4.

상기한 바와 같이, 주행풍이 임펠러부(12)의 외곽부에서 임펠러케이싱을 가로질러 빠져나가므로, 포터블 발전기(10)를 고정장치(40)의 상부에 직립 시킬 수도 있다. 즉, 포터블 발전기(10)가 고정장치(40)의 상부에 직립한 상태로, 전기차(A)의 주행 중 발생하는 주행풍의 압력을 받아 동작할 수 있는 것이다.As described above, since the traveling wind passes through the impeller casing from the outer periphery of the impeller part 12, the portable generator 10 may be made upright on the top of the fixing device 40. That is, the portable generator 10 can be operated by receiving the pressure of the running wind generated while the electric vehicle A is running while the portable generator 10 is upright on the top of the fixing device 40.

도 6은 본 발명의 일 실시예에 다른 포터블 발전기(10)가 전기차(A)에 장착된 장착 예를 도시한 도면이다.6 is a view showing an example of mounting the portable generator 10 according to an embodiment of the present invention is mounted on the electric vehicle (A).

도시한 바와 같이, 전기차(A)에 두 대의 포터블 발전기(10)가 장착되어 있다. 포터블 발전기(10)의 설치 개수나 위치는 경우에 따라 얼마든지 변경 가능하다. 가령, 차량의 본넷의 상부는 물론 (세단형 승용차의 경우) 후방의 트렁크 상부에 설치할 수도 있다.As shown, the electric vehicle A is equipped with two portable generators 10. The number or location of the portable generator 10 can be changed as much as needed. For example, it can be installed on the top of the bonnet of the vehicle, as well as the top of the trunk at the rear (in the case of a sedan type passenger car).

상기 포터블 발전기(10)는, 전기차(A)의 화살표 p방향 주행시, 발생하는 주행풍의 압력을 받아 전력을 생산하고 생산된 전력을 배터리(Z)로 전달하여 배터리의 충전율을 최대한 높게 유지한다.The portable generator 10 generates power by receiving the pressure of the driving wind generated when driving in the direction of the arrow p of the electric vehicle A and transfers the generated power to the battery Z to maintain the charging rate of the battery as high as possible.

아울러, 필요하다면, 상기 포터블 발전기(10)를 별도의 케이싱으로 감쌀 수도 있다. 이를테면 주행풍이 통과하는 윈드터널을 갖는 케이싱을 고정하고 그 내부에 배치할 수 있는 것이다.In addition, if necessary, the portable generator 10 may be wrapped with a separate casing. For example, a casing having a wind tunnel through which the running wind passes can be fixed and placed inside it.

이상, 본 발명을 구체적인 실시예를 통하여 상세하게 설명하였으나, 본 발명은 상기 실시예에 한정하지 않고, 본 발명의 기술적 사상의 범위내에서 통상의 지식을 가진 자에 의하여 여러 가지 변형이 가능하다.In the above, the present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill in the art within the scope of the technical idea of the present invention.
