1. Background
To guarantee the movability of the lower limb paretic, there are two types of the wheelchair.
The one is manual wheelchair which is limited to make a long distance and drive in slope, the other is electric wheelchair which is possible to make a long distance and easy driving in slope, but which is limited to treat for loading into a car. Therefore, we developed a power-assitive driving device to solve above problem completely which help to extend the area of the daily life and social activity
2. Contents of the developed device
power assistive driving device is composed of the four main parts, actuator, adapter for attach/detachment, controller and BLDC motor driver, optimized light-weighted frame. To dominate the market in advance with high-edge technology in comparison of the imported material, developed our device include the following function.
● Considering driving characteristic of the conventional material. DC motor based products are need to check the brush which could be worn out in 1 year. we developed a high torqued long-life bldc motor which has more than three times life cycle and it also possible to drive slope very easily.
● An exclusive BLDC motor driver and controller was developed with a view to more effective performance. Its function include power cut-off circuit at overloaded current and uniform velocity function in down-hill driving, it is also possible to cuntinuous working for a long time as it's power supplied by lithium-polymer.
● Attaching the device to the manual wheelchair, the conventional adapter is very uncomfortable and very hard to attach the device. it also make impossible to folder the wheelchair which is the merit of the manual wheelchair. To improve the utility with solving above problem, one-touchtype adapter which make it easy to attach and dettach and it is possible to just one action to touch the button.
● Light-wight and durable frame which has functions that is height adaptability. It guarantees that steering frame is applied to both front and rear direction and also possible to the adaptation of the height of the user.
● USB based receiver with ZigBee and ZigBee Transmitter with 8051 based microprocessor were developed to support with expansion of the market and mass production near the feature. It is possible to debug the system effectively and support the maintenance with low price.
3. Results.
We developed the power-assitive deiving device to improve the moving ability of the manual wheechair. Including the battery, its weigbt is up to 13.55Kg and it is possible to drive in slope with 10 degree and driving 10Km in flat terrain. One-touch based attachment device is able to attach to both front and rear part, which can folder the manual wheelchair.
4. Further stydy
● domestic/international market open based on the core-technology
● Preoccupation of the aging friendly market preparing for the aging society
● new item production using the deep relationship of the industry and hospital, and so forth.
