Advantages of using lightweight parts for carbon fiber wheelchairs

In order to meet their diverse needs for daily travel and life, the design and production of wheelchairs have begun to pursue more and more lightweight, humanized and intelligent. The frequency of wheelchair users is high in daily use, and it is necessary to ensure that the wheelchair parts are strong and durable; Of course, in daily handling and stacking, wheelchairs should also be easy to operate, so lightweight needs to be considered in the design of wheelchairs; Carbon fiber wheelchair parts can be a good combination of the above points.

The traditional wheelchair is made of steel, in order to pursue lightweight, aluminum alloy gradually replaced, and now, carbon fiber composite materials with their own lightweight performance advantages began to occupy the C position. At present, most of the wheelchairs on the market are manual, mainly driven by human power, and the lighter the weight of the wheelchair, the easier it is to operate, which can reduce the force burden on their shoulders and wrists. Carbon fiber wheelchair parts are used in electric wheelchairs, which can reduce the weight by about 30% and increase the battery life. The accessories of the wheelchair include large and small wheels, handwheel rims, seat seats, brakes, backrests, cushions, foot rests and leg rests, armrests and arm rests and other components.

In addition to lightweight, wheelchair parts also need to consider the issue of long-term use, wheelchair parts are used frequently, and they must be strong and durable. The strength of carbon fiber composite materials is about 7-10 times higher than that of metal materials, which can ensure the strength of daily use, and its fatigue resistance is good, the creep is almost 0, and the long-term high-frequency use will not cause aging and wear of parts, serious deformation, etc. In the design of carbon fiber wheelchair parts, the laying direction and thickness of the layup can be considered, so as to ensure its good bearing capacity and service life.

In addition to the above advantages, wheelchair parts are also required for corrosion resistance, some wheelchair users will have incontinence, drug dumping, etc., which requires wheelchair parts to withstand the erosion of these pollutants, carbon fiber composite materials are non-metallic inert materials, do not react with acid and alkali salts, good corrosion resistance, pollutants stick to the surface, gently wipe it, do not affect the use. In the outdoors, it is inevitable to withstand the test of ultraviolet radiation, rain or changes in high and low temperatures, and traditional metal materials are prone to rust and surface oxidation, which not only affects the appearance, but also has a cumulative impact on the overall performance of the wheelchair. Carbon fiber wheelchair parts can compensate for these shortcomings.

Among wheelchair users, there may be hemiplegia, stroke, cut-off, fracture patients, especially some patients who have just undergone surgery or are in the recovery period, in the process of using the wheelchair, in order to avoid secondary injury, it is necessary to minimize the vibration of the wheelchair. The carbon fiber wheelchair has a large damping coefficient and good shock absorption effect, which can reduce the vibration between the frame and the wheel, improve the comfort and safety of the patient, and facilitate the recovery during the rehabilitation period.

Carbon fiber composite materials have excellent properties and can also be made of complex component structures through integrated molding technology, which is an ideal material for making high-end wheelchairs. However, due to the limitation of production cost, the application of carbon fiber composite materials in wheelchairs is not very popular. According to Boshi's wheelchair manufacturer customers, with the increase of the aging population, wheelchairs are no longer limited to hospital patients, and the elderly have a great demand for wheelchairs. It is believed that with the in-depth research of carbon fiber, the application of carbon fiber wheelchair parts can become more and more popular, which is also what Boshi hopes to see the most.
