As an auxiliary tool for people with limited mobility, wheelchairs can be divided into ordinary wheelchairs and sports wheelchairs according to the usage scenarios and functional requirements. There are certain differences in the selection of raw materials between the two. This article will analyze the differences in the selection of raw materials between sports wheelchairs and ordinary wheelchairs from the following aspects.
1. Material selection
Ordinary wheelchairs: Ordinary wheelchairs mainly focus on comfort and portability, so in terms of material selection, lightweight materials such as aluminum alloys and steel pipes are mostly used. These materials have good toughness and corrosion resistance and can meet the needs of daily use.
Sports wheelchairs: Sports wheelchairs need to withstand greater forces and impacts during use, so in terms of material selection, more attention is paid to strength and rigidity. Sports wheelchairs are mostly made of high-strength aluminum alloys, carbon fiber and other materials. These materials have the advantages of light weight, high strength, and wear resistance, which can meet the needs of sports wheelchairs in high-speed movement and fierce confrontation.
2. Tires and wheels
Ordinary wheelchairs: The tires of ordinary wheelchairs are mostly solid rubber or pneumatic tires, and the wheels are generally plastic or aluminum alloy. These configurations are sufficient to cope with flat roads and slight bumps in daily use.
Sports wheelchairs: Sports wheelchairs have higher requirements for tires and wheels. Tires are mostly made of high-performance rubber materials with high wear resistance and low resistance, while wheels are made of lightweight, high-strength aluminum alloy or carbon fiber materials. Such a configuration is conducive to improving the movement speed and stability of the wheelchair and reducing the fatigue of athletes during intense exercise.
3. Seats and backrests
Ordinary wheelchairs: The seats and backrests of ordinary wheelchairs are mostly made of cloth, leather and other materials with good breathability, focusing on comfort and breathability.
Sports wheelchairs: The seat and backrest materials of sports wheelchairs must have good heat dissipation performance to reduce the body temperature of athletes during exercise. Therefore, sports wheelchairs mostly use mesh materials or special synthetic materials with good breathability. At the same time, the shape design of the seat and backrest is more in line with the athlete's body to improve stability and support during exercise.
4. Braking system
Ordinary wheelchairs: The braking system of ordinary wheelchairs mostly uses manual brakes, which are suitable for daily slow travel and temporary parking.
Sports wheelchairs: The braking system of sports wheelchairs is more complicated, using a combination of manual and electric brakes. In high-speed movement, the braking system can respond quickly to ensure the safety of athletes.
The differences in the selection of raw materials between sports wheelchairs and ordinary wheelchairs are mainly reflected in the materials, tires, seats, brake systems, etc. Sports wheelchairs focus more on the application of high-strength, lightweight, and high-performance materials to meet the needs of athletes in intense sports. Ordinary wheelchairs focus more on comfort and portability. Understanding these differences will help consumers choose the right wheelchair according to their needs.
