Abstract

PURPOSE: An electric wheelbarrow is provided to reduce manufacturing costs by simply manufacturing although having high durability and same adaptability, thereby popularizing the electric wheelbarrow at low costs. CONSTITUTION: An electric wheelbarrow comprises a battery, a motor(3), a decelerator(5), chain sprockets, and a driving lever(9). The motor is driven by using the electricity of the battery. The driving force of the motor is decelerated by the decelerator. The chain sprockets are respectively installed in one side of a wheel shaft and a shaft of the decelerator. When the driving lever turns on, the motor is driven to rotate a wheel so that the electric wheelbarrow can drive. The driving lever has a sprocket to mount a microswitch.

외발전동손수레 { Motor-driven of the wheelbarrow}Motor-driven of the wheelbarrow

본 발명은 외발손수레에 밧데리와 모터를 구성하고 동 동력으로 손수레를 주행케 하는 외발전동손수레에 관한 기술이다.The present invention relates to a power generation cart that constitutes a battery and a motor in a wheelbarrow and allows the cart to run with the power.

본 발명은 특허출원 10-2011-0033047(외발전동손수레)호의 연속 출원으로 좁은 고랑과 이랑으로 구성되고 비포장인 밭농업 환경의 특성상, 주행을 위한 에너지 소비가 적고 좁은 고랑에서 자유롭고 방향전환성이 탁월한 외발손수레는 농가의 필수품 이다. 수확기에 연속되는 운반작업으로 인해 가중되는 노력강도를 줄이기 위해 동력을 이용한 외발손수레의 필요성이 요구되고 또한 관련하여 연구된 다양한 기술이 공개되고 제품도 있지만, 외발손수레의 실용화에는 많은 문제점이 있어 농가의 외면을 받아왔다.The present invention is a continuous application of the patent application 10-2011-0033047 (foreign development cart) consisting of narrow furrows and ridges, due to the nature of the unpaved field farming environment, low energy consumption for driving, free from the narrow furrows and excellent turning direction Carts are a commodity of the farmhouse. There is a need for a powered wheelbarrow using power to reduce the strength of effort that is carried out due to the continuous transport operation during the harvesting period, and various technologies studied and related products are disclosed and there are many products for practical use of the wheelbarrow. Has been given away.

관련하여 문제점을 간략하게 분석하면, 외발전동손수레는 특성상 큰용량의 밧데리를 장착할 수 없는 구조(12V40AH 1개가 적합)여서 큰 출력을 내도록 할 시, 밧데리의 극판손상으로 밧데리의 수명이 단축되는 문제점과 손잡이 하중 해결 및 적재물 공간 확장을 위한 수단으로 바퀴의 위치가 짐받이의 중간에 위치토록 하므로서 발생하는 손수레의 전복 문제와 주행레버의 장시간 이용시 피로감 증가 및 판 매가가 비싼 문제다. 따라서 모터의 축에 토크리미트를 장착하여 출력을 제한토록 하여 과부하 및 급방전을 방지토록 하고, 일반 손수레의 체대에 적용하여 재료비 절감 및 전복방지 및 퇴비운반도 겸하도록 하여 사용율을 높이고 주행레버도 피로감을 주지 않도록 구성해야 한다.In brief analysis of the problem, the external power generation cart is a structure that cannot be equipped with a large capacity battery (one 12V40AH is suitable), so when the output is large, the battery life is shortened due to the damage of the pole plate of the battery. As a means for resolving the handle load and expanding the load space, the wheel's position is located in the middle of the rack, and the rollover problem caused by the wheelbarrow is increased, and the fatigue and increase of the selling price are high when the driving lever is used for a long time. Therefore, torque limit is attached to the shaft of the motor to limit the output to prevent overload and sudden discharge, and it is applied to the body of general cart to reduce material cost, rollover prevention, and composting conveyance to increase the utilization rate and to make the driving lever tired. It should be configured not to

The unidirectional clutch combines power and manpower with stable and mass-produced bicycle wheels, which are stable and mass-produced, and save cost, and the driving lever reduces the flat lever of the microswitch. It is formed by bending it in the form of a lever so that it can be lightly turned on and off by the index finger, and it is composed by combining a micro switch configured in the form of the lever with a frame formed under the front end of the handle of the cart.
