[0002] After investigation, it was found that for the elderly in wheelchairs who need to travel, their families will put on diapers for them to save the trouble of going to the toilet. For the elderly in wheelchairs at home, they usually need the help of their family members to go to the toilet, at least they need someone to help them to the toilet to complete the toilet. And these methods are not very comfortable for the elderly to go to the toilet. There is a toilet in the public toilets in society and there will be a handrail next to it, but there is still a great risk of falling when the elderly go to the toilet with the handrail. And the elderly at home usually have a toilet in the toilet. The toilet is indeed much more convenient for going to the toilet, but the elderly still need the help of others to go from the wheelchair to the toilet, and carry the elderly to the toilet, and then carry them back to the toilet after the elderly have finished using the toilet. There are three main products for assisting the elderly to go to the toilet: toilet chairs suitable for squat toilets, wheelchairs with built-in toilets, and wheelchairs that can be used with toilet holes. These auxiliary equipment are very simple non-powered devices, which are still very inconvenient to help the elderly go to the toilet. Summary of the invention
