Description

사륜형 전동 퍼스널 모빌리티4-wheel electric personal mobility
본 발명은 사륜형 전동 퍼스널 모빌리티에 관한 것으로, 더욱 상세하게는 사용자가 사륜을 이용한 전동 이동 수단으로 사용되는 퍼스널 모빌리티의 구조를 개선하여 전후방에 효과적으로 충격을 흡수하여 승차감을 향상시키고, 중앙에서 자동으로 폴딩되어 폴딩폭을 최소화함에 따라 보관과 이동이 용이한 사륜타입 전동 퍼스널 모빌리티를 제공함에 있다.The present invention relates to four-wheeled electric personal mobility, and more particularly, improves the structure of personal mobility, which is used as an electric transportation means for users using four wheels, to effectively absorb shocks in the front and rear to improve ride comfort, and to automatically move from the center. It is to provide a four-wheel type electric personal mobility that is easy to store and move as it is folded and minimizes the folding width.
일반적으로 퍼스널 모빌리티는 개인인 퍼스널과 이동수단인 모빌리티가 결합된 의미로써, 자전거, 킥보드와 같은 레져용이나 휠체어와 같은 의료용으로 개인이 직접적인 작동에 의해 바퀴를 구동시켜 주행을 실시하는 장치이다. In general, personal mobility means a combination of personal personal and mobility, which is a device for driving by driving wheels by direct operation of an individual for leisure such as a bicycle or kickboard or medical use such as a wheelchair.
종래의 통상적인 퍼스널 모빌리티는 사용자가 직접 구동시켜 원하는 장소로 이동하는 주행장치이다.Conventional personal mobility is a traveling device that is directly driven by a user and moves to a desired place.
이런, 퍼스널 모빌리티는 사용자가 수동으로 직접 구동하여야 함에 따라 노약자나 힘이 약한 사람들이 작동시키기 어렵고, 특히 자전거의 경우에는 넘어지지 않고 지속적으로 조작하기에는 숙련의 과정이 장시간 필요하고, 주행 중에도 지속적으로 페달을 조작하여야 함에 따라 많은 힘이 필요한 문제점이 있었다. Such personal mobility is difficult for the elderly or those with weak strength to operate as the user must drive it manually. In particular, in the case of a bicycle, a long-term skill is required to operate continuously without falling, and pedaling continuously while driving. There was a problem that required a lot of force as it had to be manipulated.
이에, 최근에는 전기의 공급으로 회전 동력을 발생시키는 전기모터와 전기모터에 전력을 공급하도록 축전하는 배터리가 소형화, 경량화되어 전동으로 구동되는 퍼스널 모빌리티가 개발되어 사용되고 있다.Accordingly, in recent years, electric motors that generate rotational power by supplying electricity and batteries that store electricity to supply power to the electric motors have been developed and used for personal mobility driven by electric power, which is made smaller and lighter.
이런, 전동 퍼스널 모빌리티 중에서 사용자가 간편하게 사용할 수 있고 전동화가 용이한 킥보드나 자전거와 같은 두개의 바퀴를 이용한 장치가 개발되어 사용되어 왔으나, 두개의 바퀴가 중심을 잡아야 함에 따라 조작이 어렵고, 작은 외력이 작용하면 전복이 발생되는 문제점이 있었다.Among these electric personal mobility, devices using two wheels such as kickboards or bicycles that can be easily used by users and are easy to electrify have been developed and used. There was a problem that overturning occurred when it worked.
즉, 킥보드와 자전거가 전동으로 작동하면서 속도가 높아진 상태에서 조작 미숙 등으로 균형을 잃거나 불균일한 도로 및 장애물에 의해 외력이 발생되면 전복되면서 탑승자가 부상을 당하는 문제점이 있었다.In other words, there is a problem in that the kickboard and the bicycle are electrically operated and the occupant is injured when the kickboard and the bicycle are overturned when the speed is increased and the balance is lost due to inexperienced operation or an external force is generated by an uneven road or an obstacle.
따라서, 안전성이 높은 휠체어의 구조를 채택하여 사륜으로 주행 성능을 높이도록 전륜과 후륜의 폭을 확장하여 주행 성능을 향상시킨 사륜형 전동 퍼스널 모빌리티가 개발되어 사용되고 있다.Therefore, a four-wheeled electric personal mobility that improves driving performance by expanding the width of the front and rear wheels to increase driving performance with four wheels by adopting a structure of a high-safety wheelchair has been developed and used.
이런, 사륜형 전동 퍼스널 모빌리티는 전력으로 구동되는 모터가 구동력 전달 수단을 통해서 전륜 또는 후륜에 선택적으로 전달하여 주행을 실시함에 따라 중량이 무겁고, 형태 변형이 어려워 접히는 구조를 제시할 수 없는 문제점이 있었다.This four-wheeled electric personal mobility has a problem in that a motor driven by electric power selectively transmits it to the front or rear wheels through a driving force transmission means to drive, so that the weight is heavy and it is difficult to change the shape, so that a folding structure cannot be presented. .
즉, 구동력 전달 수단은 벨트와 체인, 기어 조합에 의해 동력을 바퀴에 전달하는 것으로, 고정된 구조를 가지면서 중량이 무거움에 따라 폴딩되는 구조를 도입하기 어렵워 보관과 이동에 제약이 있는 문제점이 있었다.In other words, the driving force transmission means transmits power to the wheels by a combination of belt, chain, and gear, and it is difficult to introduce a structure that folds according to the heavy weight while having a fixed structure, so there is a problem in storage and movement. there was.
이에, 전기 주행장치의 이송과 보관의 용이성을 위해서 폴딩이 가능하고, 폴딩된 상태에서 주행이 가능하여 휠체어 용도로 사용이 가능하고, 전복을 방지하는 전기 주행 장치의 개발이 요구되고 있는 실정이다. Accordingly, there is a demand for the development of an electric traveling device that can be folded for ease of transportation and storage, can be used for a wheelchair by being able to travel in a folded state, and prevents overturning.
