As a core load-bearing and moving component, the wheelchair folding backrest must withstand tens of thousands, even hundreds of thousands, of opening and closing cycles without breakage, deformation, or functional failure, while maintaining a lightweight
In today's world, with high-speed operation of modern industrial equipment, frequent starts and stops of vehicles, building structures bearing wind loads and earthquakes, and even the pursuit of quiet and comfortable home appliances, vibration and impact
Wheelchair brakes achieve the ideal effect of "a light press, a steady stop"—a perfect balance of low operating force and high braking force—through optimized leverage principles, upgraded friction materials, structural innovation, and ergonomic design.
For wheelchair users, every stop is a matter of safety and dignity. This is achieved by the seemingly simple yet crucial braking system.
In wheelchair design, the backrest is far more than just a flat structure for leaning against; it's a key component affecting the overall dynamic performance of the wheelchair.
The damping shock absorber, with its unique "controllable energy dissipation" mechanism, has become a key technology for ensuring the stable operation of precision instruments. It does not rely on active power supply but intelligently converts harmful vib
