Abstract

The invention relates to a wheelchair, in particular to an intelligent wheelchair based on a Mecanum wheel mechanism, which can complete rotation in all directions or angles, is flexible in operation and large in degree of freedom, and is characterized in that four Mecanum wheels are arranged below a base and are independently driven by four motors respectively, a controller and a seat are arranged on the upper side of the base, the seat comprises armrests, a seat body and a seat back, an operation panel connected with the controller is arranged on the armrests, and a motor control circuit used for controlling the working states of the four motors is arranged in the controller. In the working process of the intelligent wheelchair, the rotating directions and the rotating speeds of the four independent stepping motors are controlled through one controller, then the four Mecanum wheels on the base are controlled to move and steer, translation of the base and a wheelchair on the base in all directions such as advancing and retreating can be achieved, and in-situ clockwise or anticlockwise rotation can be completed.

Description

Technical field: [0001] The invention relates to a wheelchair, in particular to an intelligent wheelchair based on a mecanum wheel mechanism capable of rotating in various directions or angles, with flexible operation and large degrees of freedom. Background technique: [0002] With the aging trend of our society becoming more and more serious, the number of elderly people who are alone at home without care is increasing rapidly. Many elderly people have limited mobility due to age, and thus need wheelchairs to assist them in activities at home. [0003] The wheelchairs currently on the market are still mostly mechanical wheelchairs with a single function, which has a single function and high manual operation intensity, which is not very helpful to the elderly. [0004] With the development of new transmission technology and artificial intelligence technology, more and more robotic technologies have been widely used. [0005] The feature of the Mecanum wheel is that it can...
