Active safety device of intelligent wheelchair

Abstract

The invention discloses an active safety device of an intelligent wheelchair. The active safety device comprises a chassis component, a longitudinal movement component, a lateral movement component and a controller, wherein the chassis component comprises a chassis and shock absorption mechanisms which are respectively arranged on four corner ends of the chassis, and the shock absorption mechanisms are connected with a motor shaft of a driving wheel, and comprise four pressure sensors, the four pressure sensors are respectively located at positions of the four corner ends of the chassis and are used for collecting pressure data of four directions; and the controller is electrically connected with driving motors of the lateral movement component and the longitudinal movement component, andthe four pressure sensors respectively, and is used for controlling the action processes of the lateral movement component and the longitudinal movement component. The active safety device disclosed by the invention can actively perform protection to a certain extent, and can perform avoidance before risks; and the active safety device can make judgment before a user has dumping hidden danger, andcan adjust the state of the user timely, so that the safety of the user is increased, and the dumping risks of the user are reduced.

Description

technical field [0001] The invention relates to the technical field of wheelchairs, in particular to an active safety device for an intelligent wheelchair. Background technique [0002] The aging trend of my country's population is intensifying. Many elderly people have various types of problems after the deterioration of their lower limb skills. Among them, travel difficulties are the most common and basic problem. Most elderly people cannot walk long distances due to the deterioration of their physical functions. Needing assistance tools, more people choose electric wheelchairs or smart wheelchairs. However, during the travel of electric wheelchairs, the problem of users falling occasionally occurs. Especially when going up and downhill, the problems of toppling forward, falling backward, and rolling over have caused secondary injuries to the user's health. [0003] The technical characteristics of the existing products are as follows: [0004] 1. A common foldable elect...

AI Technical Summary

Problems solved by technology

Although the rear side is designed with anti-dumping wheels, there is still a risk of rearward toppling

And there are no protective measures or remedial measures for rollover on the left and right sides

[0009] The electric wheelchair mentioned above 3 is designed with the seat leveling function when going uphill or downhill, but when going uphill, its center of gravity changes relatively greatly and moves to the rear side more, and the rear side is not designed with anti-dumping wheels. risk of back toppling

In addition, the electric wheelchair has no protective measures or remedial measures for rollover on the left and right sides.
