一款智能减震坐立助行器的研制及应用方式

Development and Application of An Intelligent Shock-absorbing Sitting Walker

目的设计一种集智能减震、安全性高、带有报警和心率监测装置为一体的坐立助行器。方法用铝合金支架充当助行器的主体,顶端设置U形软质臂托和L形把手,下端设置万向轮和防滑地垫。减震座椅通过液压杆与减速电机相连,座椅内部设置GPS定位系统、报警装置和心率监测装置,并运用有限元软件Abaqus 2021对减震座椅进行了受力分析。结果助行器主体轻便易携,承受能力强,U形软质臂托和L形把手可以增加使用者体验感,万向轮和防滑地垫的结合可以让使用者安全省力。当使用者想要坐下休息时,通过调节开关可以让减速电机带动减震座椅翻转托扶老人缓慢坐下,实现安全独立的休息,且减震座椅可以承受相应应力。结论智能减震坐立助行器可以节省人力,安全可靠,符合市场需求和使用者需要。

Objective To design a sitting walking aid with intelligent shock absorption,high safety,alarm and heart rate monitoring device.Methods Aluminum alloy bracket is used as the main body of the walker.U-shaped soft arm bracket and L-shaped handle are arranged at the top,and universal wheel and anti-slip floor mat are arranged at the bottom.The shock-absorbing seat is connected to the geared motor through a hydraulic rod,and the seat is equipped with GPS,alarm device and heart rate monitoring device,and the finite element software Abaqus 2021 is used to analyze the force of the shock absorbing seat.Results The main body of the walker is light and easy to carry,with strong bearing capacity.The U-shaped soft arm rest and L-shaped handle can increase the sense of user experience.The combination of universal wheel and anti-slip floor mat can make the user safe and labor-saving.When the user wants to sit down and rest,the switch can be adjusted to drive the shock absorbing seat to turn over and support the elderly to sit down slowly through the deceleration motor,so as to realize the safe and independent rest,and the shock absorbing seat can withstand the corresponding stress.Conclusion The intelligent shock-absorbing sitting and standing walker saves manpower,is safe and reliable,and meets market demand and user needs.
