The invention relates to the technical field of medical auxiliary equipment and discloses a height-adjustable wheelchair auxiliary device based on the eccentric wheel principle. The device includes asmall roller; a fixed rod is fixedly connected to the interior of the small roller; a supporting frame is fixedly connected to the surface of the fixed rod; wheelchair legs are fixedly connected to the top of the supporting frame; a protective shell is fixedly connected to the surfaces of the wheelchair legs; a seat is movably connected to the top of the protective shell; a lifting mechanism is movably connected into the protective shell; armrests are fixedly connected to the surface of the seat; and a backrest is fixedly connected to the surface of the seat. According to the height-adjustablewheelchair auxiliary device based on the eccentric wheel principle, through mutual rotation of a first rotary disc, a second rotary disc, a third rotary disc, a fourth rotary disc and a first gear and a second gear, the seat can be driven to move upwards, the requirement for adjusting the height of the seat is met, and when a user uses the washstand, the requirement of the user can be met by adjusting the height.
Description
technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a wheelchair auxiliary device capable of adjusting height based on the principle of an eccentric wheel. Background technique [0002] With the increase of the aging population in society and the continuous growth of China's population, the number of people with disabilities such as the elderly and the disabled is also increasing. Therefore, people's use of wheelchairs in life or rehabilitation has also increased. [0003] Wheelchairs help people with reduced mobility to enrich their outdoor life, bring convenience to their lives, improve their quality of life, and at the same time reduce the burden on medical staff or family members. However, most of the current wheelchairs still have some inconveniences in actual use: [0004] At present, the height of most wheelchairs is fixed. On the one hand, due to the different heights of each person, the legs and feet ...
