Description

수동변속장치가 구비된 전기자전거{A TRANSMISSION OF ELECTRIC BYCICLE}Electric Bicycle with Manual Transmission {A TRANSMISSION OF ELECTRIC BYCICLE}

본 발명은 전기자전거의 변속장치에 관한 것으로, 모터에서 발생되는 동력을 전기자전거의 구동축으로 전달하는 과정에서 사용자의 필요에 따라 수동으로 저속과 고속으로 변속이 가능한 수동변속장치를 구비한 전기자전거에 관한 것이다.The present invention relates to a transmission of an electric bicycle, the electric bicycle having a manual transmission that can be shifted to low and high speed manually according to the user's needs in the process of transmitting power generated from the motor to the drive shaft of the electric bicycle. It is about.

전기자전거는 전기를 동력으로 사용하여 차륜을 구동시키는 자전거로서, 특히 노약자나 장애인과 같이 자력에 의하여 자전거를 운전할 수 없는 사람에게 애용되고 있다. 또한, 정상인이라도 중장거리를 이동하는 경우이거나 무거운 중량의 화물을 탑재한 상태의 운전시 사용되고 있다. 아울러 자전거의 동력원이 전기이기 때문에 환경친화적이며, 자원의 절감차원에서 바람직한 운송수단이라 할 수 있다.Electric bicycles are bicycles that drive electric wheels using electricity as power, and are particularly used by people who cannot drive bicycles by themselves, such as the elderly and the disabled. In addition, even a normal person is used in the case of moving a medium or long distance or when driving with a heavy load. In addition, since the power source of the bicycle is electric, it is environmentally friendly and can be said to be a preferable means of transportation in terms of resource saving.

일반적으로 전기자전거는 동력원인 배터리에서 제어부를 통해 구동원인 모터로 전원이 인가되면, 모터의 회전력이 전기자전거의 구동축으로 전달되어 운전이 실시된다. 운전중인 운전자는 여러가지 운전상황에 따라 전기자전거의 속도를 가변시키게 된다. 종래의 전기자전거는 주행중 오르막길을 운행하거나, 과도한 중량의 화물을 탑재한 상태로 주행하는 경우로 인해 전기자전거의 구동축에 부하가 크게 걸리면 수동으로 속도를 조절하거나, 또는 페달을 밟는 힘을 센싱하는 센서와 같은 전자장치에 의해 속도를 조절함으로써 전기자전거의 구동축에 걸리는 부하를 해소하는 방법을 사용하였는데, 이와같은 속도 조절방법은 모터측에 걸리는 부하도 함께 상승되어 모터 소손의 위험과 더불어 전력의 소모량이 커지는 문제가 있어, 이에 대한 해결방안으로 도 6에 도시된 바와 같이 기계식 자동 변속장치를 사용하여 자전거의 구동축에 작용되는 부하의 증감에 따라 자동으로 변속을 실시하도록 하여, 모터의 부하상승으로 인한 소손과 전력의 소모량이 커지는 것을 방지하고 있다.In general, when the electric bicycle is powered from the battery which is the power source to the motor which is the driving source through the control unit, the rotational force of the motor is transmitted to the drive shaft of the electric bicycle to perform the operation. The driver who is driving changes the speed of the electric bicycle according to various driving conditions. Conventional electric bicycle is a sensor that adjusts the speed manually or senses the pedaling force when the driving shaft of the electric bicycle is heavily loaded due to driving uphill while driving or driving with an excessive load. The speed control method is used to reduce the load on the drive shaft of the electric bicycle by controlling the speed by the electronic device. The speed control method also increases the load on the motor side, which leads to the risk of burnout and the consumption of power. There is a problem that increases, as a solution for this, by using a mechanical automatic transmission as shown in Figure 6 to perform the shift automatically according to the increase and decrease of the load applied to the drive shaft of the bicycle, the damage caused by the load increase of the motor It is preventing excessive consumption of power.

그러나 이러한 기계식 자동변속장치는 마찰기어(17)에 작용하는 힘의 크기에 따라 고정하우징(11)내에서 움직이는 이동하우징(13)의 변위량에 의해 변속여부를 결정해야 하므로 주행의 조건에 따라 변속되는 시기가 일정하지 않고, 이동하우징(13)을 정확하게 동작하게 하기 위해 정교하고 복잡한 부품을 필요로 하여 제조상의 문제점이 많았다.However, such a mechanical automatic transmission is to be shifted according to the driving conditions since the shift should be determined by the displacement of the movable housing 13 moving in the fixed housing 11 according to the magnitude of the force acting on the friction gear 17. The timing is not constant, and there are many manufacturing problems due to the necessity of elaborate and complicated parts in order to operate the mobile housing 13 accurately.

본 발명은 상기와 같은 문제점을 해결하기 위해 창안된 것으로서, 본 발명의 목적은 전기자전거에서 변속을 필요로 하는 시기에 사용자의 판단에 따라 수동으로 변속되게 하면서 변속장치의 구조를 단순하게 하여 향후에 발생할 유지 및 보수에 따른 문제를 최소화함으로써, 제조공정과 부품수를 대폭줄여 작업생산성을 보다 향상시킬 수 있는 수동변속장치를 구비한 전기자전거를 제공하는데 있다.The present invention was devised to solve the above problems, and an object of the present invention is to simplify the structure of the transmission device in the future while manually shifting according to a user's judgment at a time when a shift is required in an electric bicycle. By minimizing the problems caused by the maintenance and repair to occur, it is to provide an electric bicycle with a manual transmission that can significantly improve the work productivity by significantly reducing the number of manufacturing processes and parts.

변속레버(80)를 고속으로 하였을때 동력의 전달과정은 모터(60) → 구동축(61) → 구동기어(62) → 연동기어(63) → 제1 회전축(66) → 클러치(70) → 제1 고속기어(65) → 제2 고속기어(69) → 제2 회전축(67) → 마찰기어(90) → 타이어(5)가 된다.When the shift lever 80 is set at a high speed, the process of transmitting power is performed by the motor 60 → the drive shaft 61 → the drive gear 62 → the interlocking gear 63 → the first rotation shaft 66 → the clutch 70 → the first. 1, the high speed gear 65 → the second high speed gear 69 → the second rotary shaft 67 → the friction gear 90 → the tire 5.

반대로 오르막길을 주행하거나 무거운 짐으로 인해 부하가 많이 걸릴때는 변속레버(80)를 저속으로 변경하면 클러치(70)의 마찰판(70a)이 저속기어 마찰판(64a)과 결합되면서 모터(60)의 회전력이 제1 저속기어(64)와 제2 저속기어(68)를 통해 마찰기어(90)에 전달되고 마찰기어(90)와 접촉하는 타이어(5)를 구동하여 저속으로 주행하게 된다.On the contrary, when driving uphill or heavy load, when the shift lever 80 is changed to a low speed, the friction plate 70a of the clutch 70 is engaged with the low gear friction plate 64a and the rotational force of the motor 60 is increased. The first low gear 64 and the second low gear 68 are transmitted to the friction gear 90 and drive the tire 5 in contact with the friction gear 90 to drive at a low speed.

변속레버(80)를 저속으로 하였을때 동력의 전달과정은 모터(60) → 구동축(61) → 구동기어(62) → 연동기어(63) → 제1 회전축(66) → 클러치(70) → 제1 저속기어(64) → 제2 저속기어(68) → 제2 회전축(67) → 마찰기어(90) → 타이어(5)가 된다.When the shift lever 80 is set at a low speed, the process of transmitting power is performed by the motor 60 → the drive shaft 61 → the drive gear 62 → the interlocking gear 63 → the first rotational shaft 66 → the clutch 70 → the first. 1, the low speed gear 64 → the second low speed gear 68 → the second rotary shaft 67 → the friction gear 90 → the tire 5.

또한 변속장치를 사용하지 않고 폐달에 의해서만 자전거를 운행할 때는 상기 마찰기어가 항시 타이어에 접촉되어 있어 모터는 전원이 인가되지 않아도 계속 회전하게 되어 과부하로 인한 모터의 손상을 방지하기 위해 상기 마찰기어내부에 프리기어를 구비하였다.In addition, when the bicycle is driven only by the pedal moon without using the transmission, the friction gear is always in contact with the tire so that the motor keeps rotating even when the power is not applied. It was equipped with a pregear.

상술한 바에서는, 변속레버(80)를 직접 조작하는 방법을 설명하였으나, 변속레버(80)에 와이어(85)을 연결하여 전기자전거의 손잡이에서 조작하는 것도 가능하다.In the above-described bar, a method of directly operating the shift lever 80 has been described, but it is also possible to connect the wire 85 to the shift lever 80 to operate the handle of the electric bicycle.

핸들에 일측에 스위치(86)가 구비되어 스위치 조작에 의해 와이어(85)를 잡아당기면 상기 와이어(85)에 연결된 유동부재(83)가 유동하게 되어 변속레버(81)가 힌지회동하면서 저속으로 클러치의 마찰판(70a)을 제 1저속기어의 마찰판(64a)에 결합시켜 저속운행이 가능하며 반대로 스위치 조작에 의해 잡아 당겼던 와이어(85)를 풀면 스프링(84)의 탄성력에 의해 유동부재(83)를 밀게 되면 변속레버(81)는 클러치의 마찰판(70b)을 제 1고속기어의 마찰판(65a)에 결합시켜 고속운행이 가능하다.When the handle 86 is provided on one side of the handle and pulls the wire 85 by the switch operation, the flow member 83 connected to the wire 85 flows, and the shift lever 81 is hinged and clutched at a low speed. The friction plate 70a is coupled to the friction plate 64a of the first low speed gear, and low-speed operation is possible. On the contrary, when the wire 85, which is pulled by the switch operation, is released, the flow member 83 is released by the elastic force of the spring 84. When pushing the gear shift lever 81 is coupled to the friction plate (70b) of the clutch to the friction plate (65a) of the first high speed gear is capable of high speed operation.

또한 전기자전거의 타이어(5)에 마찰기어(90)가 적용되는 실시예를 기술하였으나, 제2 회전축(67)에 마찰기어(90)가 아닌 체인기어를 설치하고 전기자전거의 구동축(9)에 체인을 연결하여 동력을 전달하는, 체인구동방식에 있어서도 본 발명의 수동변속장치가 구비된 자전거의 활용이 가능하며, 상기 실시예에 기술한 후륜 뿐만 아니라, 이를 전륜에 적용하는 경우에도 동일한 작용 및 효과를 얻을 수 있다.In addition, although the embodiment in which the friction gear 90 is applied to the tire 5 of the electric bicycle has been described, a chain gear other than the friction gear 90 is installed on the second rotation shaft 67 and the driving shaft 9 of the electric bicycle is installed. In the chain drive system that connects the chain and transmits power, the bicycle equipped with the manual transmission of the present invention can be utilized, and the same action and the case of applying the rear wheel as described in the above embodiment to the front wheel and The effect can be obtained.

상술한 바와 같이, 본 발명에 의하면 전기자전거에서 변속을 필요로 하는 시기에 사용자의 판단에 따라 정확하게 변속되게 하면서 변속장치의 구조를 단순하게하여 향후에 발생할 유지 및 보수에 따른 문제를 최소화 할 수 있고, 제조에 사용하는 부품수를 줄여 작업생산성을 향상시키면서 제조비용을 절감하는 효과가 있다.As described above, according to the present invention, it is possible to minimize the problems caused by the maintenance and repair in the future by simplifying the structure of the transmission device while accurately shifting according to the user's judgment at the time when the electric bicycle needs to be shifted. As a result, the number of parts used in manufacturing is reduced, thereby improving work productivity and reducing manufacturing costs.
