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.
Conclusions:
The intelligent shock-absorbing sitting and standing walker saves manpower, is safe and reliable, and meets market demand and user needs.
