Wheelchair stability detection device and detection method

Abstract

The invention provides a wheelchair stability detection device and method, belonging to the technical field of wheelchair balance detection. The beneficial effects of the present invention are: the present invention can make the distance between each wheel of the wheelchair be calculated by the known data measured by the existing balance panel, avoiding manpower measurement, fast and accurate; making the load center point of the wheelchair and The center of gravity of the wheelchair does not require a cumbersome and complicated detection process, and can scientifically and reasonably measure the changes in the stability of the wheelchair, providing an intuitive and effective basis for the formulation of a plan to improve the stability of the wheelchair; it is convenient for the production and use of wheelchairs. The evaluation has greatly guaranteed the personal safety of the wheelchair user; in addition, the sensor layout is reasonable and the structure is exquisite, and it is not disturbed by the lateral force when testing the stability of the wheelchair, and the measurement results are accurate, which can scientifically and reasonably detect the stability of the wheelchair vehicle .

Description

Technical field [0001] The invention relates to the technical field of wheelchair balance detection, in particular to a stability detection device and method for wheelchair vehicles. Background technique [0002] Wheelchair vehicles are an important transportation and rehabilitation tool for physically disabled patients and the elderly and infirm. Patients with physical disabilities can not only move freely with the assistance of wheelchair vehicles, but more importantly, they can use wheelchair vehicles to exercise and participate in social activities. Therefore, wheelchair vehicles play a positive role in improving the quality of life and work of patients with physical disabilities and the elderly and infirm. [0003] However, with the increase in wheelchair vehicle users, accidents caused by wheelchairs also increase. According to statistics, there are approximately 67 million wheelchair users in the world, accounting for about 1% of the global population. Every year, more tha...

Problems solved by technology

[0007] In the existing technology, the stability evaluation of wheelchair vehicles has the following disadvantages: 1. The distance between the wheels of wheelchair vehicles still needs to be measured manually, which is time-consuming and labor-intensive

2. The center point of the load of the wheelchair vehicle and the center of gravity of the wheelchair vehicle can only be calculated through precise laboratory instruments and computer software modeling. The process is cumbersome and complicated, and the detection cost is high, which is not conducive to school research and enterprise research and development

3. The real-time change curve of the center of gravity of the wheelchair vehicle during the movement cannot be simply measured, and it is impossible to scientifically and reasonably measure the change of the balance of the wheelchair vehicle

There is currently no comprehensive and comprehensive stability testing method for wheelchair vehicles
