Description

휴대 자전거Mobile bicycle
본 발명의 실시예는 휴대 자전거에 관한 것이다.An embodiment of the present invention relates to a portable bicycle.
일반적으로 사용자의 답압력을 이용하여 전륜이나 후륜을 구동시킴으로써 화물을 운반하거나 이동수단으로서의 기능을 수행하는 자전거는 인력을 이용한 대표적인 교통수단의 하나로서 널리 사용되어 왔으며, 특히 최근에는 운동기구로서의 건강증진효과와 함께 레크레이션 수단으로서의 다양한 응용이 가능한 한편, 환경친화적인 특성에 의해 수요가 점차 확산되고 있다.In general, bicycles that carry cargo or perform functions as a means of transportation by driving the front wheels or the rear wheels using the user's response pressure have been widely used as one of the representative means of transportation using manpower. Along with the effects, various applications as recreational means are possible, while demand is gradually spreading due to environmentally friendly characteristics.
이와 같은 자전거는 통상적으로 프레임, 포크, 안장 및 핸들 등으로 구성되는 지지부분과, 크랭크 및 패달 등으로 구성되는 동력접수부분 및 체인 및 스프라켓과 변속장치 등으로 구성되는 전동부분으로 구성된다.Such a bicycle is typically composed of a support portion composed of a frame, a fork, a saddle and a handle, a power receiving portion composed of a crank and a pedal, and an electric portion composed of a chain, a sprocket, a transmission, and the like.
한편, 상기한 바와 같은 통상적인 구조의 자전거는 트러스 구조의 다아몬드형 프레임을 구조체로 사용함으로써 사용자의 신장에 비례하여 고중량과 함께 대형의 크기를 갖게 되는데, 이와 같은 대형의 프레임을 구조체로 사용한 자전거는 우수한 주행특성과 기계적 특성을 갖는 반면, 넓은 점유공간을 필요로 한다.On the other hand, the bicycle of the conventional structure as described above has a large size with a heavy weight in proportion to the height of the user by using the truss-shaped diamond-shaped frame as a structure, the bicycle using such a large frame as a structure While having excellent running and mechanical properties, it requires a large occupied space.
따라서, 트러스 구조를 갖는 다이아몬드형 프레임을 채용한 자전거는 주행과정에서 안정적인 특성을 보장하는 반면, 미사용시에는 넓은 점유공간을 필요로 함으로써 엘리베이터를 통한 이동이나 실내보관이 어렵하고, 주행과정에서 버스나 지하철과 같은 대중교통의 이용을 병행하는 윤행이 곤란하며, 승용차를 통한 적재시에는 별도의 고정수단이 필요하다는 등의 문제점이 따른다.Therefore, the bicycle adopting the truss-shaped diamond frame ensures stable characteristics during the driving process, while when not in use, it requires a large occupied space, making it difficult to move through the elevator or to store the room. It is difficult to travel in parallel with the use of public transportation such as subways, and when loading through a passenger car, a separate fixing means is required.
이에 따라 근래에 개발된 자전거는 프레임과 같이 많은 공간을 차지하는 부품을 절첩가능하게 구성함으로써 실내보관이 원활히 이루어지도록 하는 한편, 이동 및 운반과정에서 필수공간을 최소화하도록 한다.Accordingly, recently developed bicycles are configured to be able to fold up components that occupy a large amount of space such as a frame so that indoor storage can be made smoothly while minimizing essential spaces in the process of transportation and transportation.
그러나, 종래 기술에 따른 자전거는 휴대 또는 보관을 용이하게 하기 위한 구조적 특징으로 인하여, 각 구성의 고정이 견고하지 못하여 구조적 안정성이 떨어지며 조립과 조작이 불편하였다.However, the bicycle according to the prior art, due to the structural features for easy carrying or storage, the fixing of each component is not strong, structural stability is poor and assembly and operation was inconvenient.
또한, 종래의 휴대 자전거는 휴대 기능에만 한정되어, 사용자의 요구에 따른 다양한 기능을 제공하지 못하는 문제점이 있었다.In addition, the conventional portable bicycle is limited to a portable function, there is a problem that can not provide a variety of functions according to the needs of the user.
본 발명은 전술한 문제를 해결하기 위해 안출된 것으로서, 본 발명에 따른 휴대 자전거는 휴대성을 최대화하면서도, 사용자의 필요에 따라 배터리와 모터에 의해 구동되는 휴대 자전거를 제공하여, 사용자의 다양한 주행 환경에 편리하게 사용할 수 있도록 하고자 한다.The present invention has been made to solve the above-described problem, the mobile bicycle according to the present invention while maximizing portability, while providing a portable bicycle driven by a battery and a motor according to the user's needs, various driving environment of the user It is intended to be used conveniently.

도 1에 도시된 바와 같이, 본 발명의 일실시예에 따른 휴대 자전거는 수평 프레임(110), 조향 하우징(120), 조향 포스트(130), 포크 프레임(140), 베어링(118), 안장 포스트(150) 및 페달 프레임(160)을 포함하여 구성될 수 있다.As shown in Figure 1, the portable bicycle according to an embodiment of the present invention is a horizontal frame 110, steering housing 120, steering post 130, fork frame 140, bearing 118, saddle post 150 and the pedal frame 160 may be configured.
도 1에 도시된 바와 같이 본 발명의 일실시예에 따른 휴대 자전거는 수평 프레임(110)이 선형으로 길게 형성되고, 상기 수평 프레임(110)은 수직 프레임(170)에 삽입되도록 구성되므로 크기를 축소하여 차량에 탑재하거나 휴대가 용이하다.As illustrated in FIG. 1, the mobile bicycle according to the exemplary embodiment of the present invention has a horizontal frame 110 formed to be linearly long, and the horizontal frame 110 is configured to be inserted into the vertical frame 170, thereby reducing the size. It is easy to mount on the vehicle or to carry.
수평 프레임(110)의 선단에는 헤드 튜브(115)가 형성되며, 수평 프레임(110)의 선단의 헤드 튜브(115)에는 앞바퀴의 지지를 위한 포크 프레임(140)이 회전 가능하게 지지된다.A head tube 115 is formed at the front end of the horizontal frame 110, and the fork frame 140 for supporting the front wheel is rotatably supported by the head tube 115 at the front end of the horizontal frame 110.
조향 하우징(120)은 상기 헤드 튜브(115)의 일측에 결합되며, 조향 포스트(120)는 상기 조향 하우징(120)에 삽입되어 상기 조향 하우징(120)을 관통한다.The steering housing 120 is coupled to one side of the head tube 115, and the steering post 120 is inserted into the steering housing 120 to penetrate the steering housing 120.
또한, 상기 포크 프레임(140)은 상기 헤드 튜브(115)의 타측에서, 상기 헤드 튜브(115)를 관통한 상기 조향 포스트(130)와 결합된다.In addition, the fork frame 140 is coupled to the steering post 130 through the head tube 115 at the other side of the head tube 115.
그에 따라, 조향 포스트(130)가 회전하면 회전력이 포크 프레임(140)에 전달된다.Accordingly, the rotational force is transmitted to the fork frame 140 when the steering post 130 rotates.
도 2에 도시된 바와 같이 상기 수평 프레임(110) 내에는 배터리 팩(210)과 모터 제어부(220)가 삽입된다.As shown in FIG. 2, the battery pack 210 and the motor controller 220 are inserted into the horizontal frame 110.
상기 배터리 팩(210)은 전륜 바퀴(145)를 구동시키기 위한 전원을 공급하며, 보다 상세하게는 포크 프레임(140)에 결합된 전륜 바퀴(145)를 구동시키는 모터(146)에 전원을 공급하며, 모터 제어부(220)는 이와 같이 상기 배터리 팩(210)에 의해 전원을 공급받는 모터(146)를 제어한다.The battery pack 210 supplies power for driving the front wheel 145, and more specifically, powers the motor 146 for driving the front wheel 145 coupled to the fork frame 140. In this way, the motor controller 220 controls the motor 146 supplied with power by the battery pack 210.
또한, 토크 감지 센서(161)가 수직 프레임(170)에 결합되는 페달(160)의 회전 토크를 감지한다.In addition, the torque sensor 161 detects the rotational torque of the pedal 160 coupled to the vertical frame 170.
따라서, 본 발명의 일실시예에 따르면 모터 제어부(220)가 상기 토크 감지 센서(161)에서 감지한 상기 페달(160)의 회전 토크에 상응하게 상기 모터(146)의 동작을 제어할 수 있다.Therefore, according to an embodiment of the present invention, the motor controller 220 may control the operation of the motor 146 corresponding to the rotational torque of the pedal 160 sensed by the torque sensor 161.
보다 상세하게 설명하면, 상기 모터 제어부(220)가 상기 토크 감지 센서(161)에서 상기 페달(160)의 회전 토크가 발생하지 않은 것으로 판단하면, 상기 모터(146)가 동작하도록 제어하고, 상기 토크 감지 센서(161)에서 상기 페달(160)의 회전 토크가 발생한 것으로 판단하면, 상기 모터(146)가 동작하지 않도록 제어할 수 있도록 하여, 사용자가 휴대 자전거의 페달(160)을 돌리지 않는 경우에는 배터리 팩(210)의 전원의 힘으로 전륜 바퀴(145)에 설치된 모터(146)가 동작할 수 있으며, 사용자가 휴대 자전거의 페달(160)을 돌리는 경우에는 배터리 팩(210)의 전원을 차단하여 사용자의 페달(160)을 돌리는 힘만으로 휴대 자전거가 이동하도록 할 수 있다.In more detail, when the motor controller 220 determines that the rotational torque of the pedal 160 is not generated by the torque sensor 161, the motor 146 is controlled to operate and the torque is controlled. If it is determined by the detection sensor 161 that the rotational torque of the pedal 160 is generated, the motor 146 can be controlled to not operate so that the battery does not operate when the user does not turn the pedal 160 of the mobile bicycle. The motor 146 installed on the front wheel 145 may operate by the power of the pack 210, and when the user rotates the pedal 160 of the mobile bicycle, the user cuts off the power of the battery pack 210. It is possible to move the portable bicycle only by the force of turning the pedal 160.
또 달리, 상기 모터 제어부(220)가 상기 토크 감지 센서(161)에서 상기 페달(160)의 회전 토크가 기준값 이하이면 상기 모터(146)가 동작하도록 제어하고, 상기 토크 감지 센서(161)에서 상기 페달(160)의 회전 토크가 기준값 이상이면 상기 모터(146)가 동작하지 않도록 제어하여, 사용자의 페달(160)을 돌리는 속도가 기준값 이하인 경우에는 배터리 팩(210)의 전원의 힘으로 전륜 바퀴(145)에 설치된 모터(146)가 동작하도록 하여, 휴대 자전거의 이동 속도를 일정 속도 이상으로 유지할 수 있다.Alternatively, the motor controller 220 controls the motor 146 to operate when the torque of the pedal 160 is less than or equal to the reference value in the torque sensor 161, and the torque sensor 161 controls the motor 146 to operate. When the rotational torque of the pedal 160 is greater than or equal to the reference value, the motor 146 is controlled to not operate. When the speed at which the user rotates the pedal 160 is less than or equal to the reference value, the front wheels may be driven by the power of the battery pack 210. The motor 146 installed in the 145 can be operated to maintain the moving speed of the portable bicycle at a predetermined speed or more.
