Wheelchair stability detection device and method

Abstract

The invention provides a wheelchair stability detection device and a wheelchair stability detection method, which belong to the technical field of wheelchair balance detection. The wheelchair stability detection device and the wheelchair stability detection method have the beneficial effects that: the distance between wheels of a wheelchair can be calculated according to known data measured by means of an existing balance panel, manual measurement is avoided, and the measurement is quick and precise; a load center point and a gravity center point of the wheelchair do not need a tedious and complex detection process, the wheelchair stability variation condition can be measured scientifically and reasonably, and an intuitive and effective basis is provided for making a wheelchair stability scheme; the evaluation of wheelchair production and use safety is facilitated, and the personal safety of a wheelchair user is greatly ensured; in addition, the sensor layout is reasonable, the structure is delicate, wheelchair stability detection is not interfered by a lateral force, the measurement result is precise, and the wheelchair stability can be detected scientifically and reasonably.

Description

Technical field [0001] The invention relates to the technical field of wheelchair balance detection, in particular to a stability detection method and device 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
