Power unit for wheelchair

This hydraulic power unit specifically designed for electric wheelchairs is a core power component tailored for electric wheelchairs and rehabilitation care equipment. Featuring a miniaturized, low-noise, and high-safety integrated design, it provides stable and smooth hydraulic power for functions such as backrest adjustment, leg lift, seat height adjustment, and switching between lying down and sitting up. Balancing comfort, safety, and durability, it is an ideal power accessory for high-end electric wheelchairs, rehabilitation care beds, and other assistive devices.

II. Core Advantages

✅ Ultimate silent and comfortable experience

Equipped with a low-noise hydraulic pump and shock-absorbing buffer structure, the operating noise is ≤55dB, significantly lower than the industry standard. The adjustment process is smooth and seamless, without any jolts or impacts, completely eliminating the harsh noise of traditional motors. It provides users with a quiet and comfortable experience, without disturbing rest and daily communication.

✅ Miniaturized integrated design

The entire machine is compact in size, tightly structured, and lightweight, allowing it to be easily embedded into the limited space of a wheelchair chassis without occupying additional space or affecting the folding and portability of the wheelchair. With standardized installation interfaces, it is compatible with the modification and matching of most electric wheelchairs and rehabilitation equipment, and is convenient to install.

✅ Comprehensive security protection

Equipped with multiple safety protection mechanisms: built-in overload protection valve and bi-directional lock valve to prevent seat loss of control and sudden descent caused by misoperation; equipped with manual emergency pressure relief valve, which can be manually reset smoothly in case of power failure/malfunction, ensuring user safety; meets medical device-level safety standards and has passed rigorous load and lifespan tests.

✅ Low power consumption and long battery life

Equipped with high-efficiency energy-saving motors and optimized oil circuit design, it features low energy consumption and minimal heat generation, significantly reducing the load on the wheelchair battery and extending the endurance time on a single charge. It is compatible with DC12V/24V universal wheelchair voltage, eliminating the need for an additional power source. It directly interfaces with the wheelchair control system, offering strong compatibility.

✅ Medical-grade durable quality

The key sealing components are made of medical-grade oil-resistant and anti-aging materials, while the oil tank is constructed from food-grade oil-resistant engineering plastic, ensuring no odor and leak prevention. The entire machine has passed IP54 dust and splash proof certification, capable of withstanding dust and water stains in daily use. It boasts a long service life, low maintenance costs, and is suitable for long-term high-frequency use.

Support on-demand customization of motor parameters, pressure flow, valve group functions, and oil tank specifications. The oil circuit design can be optimized according to the functional requirements of the wheelchair (such as backrest adjustment only, multi-action linkage). Provide specialized customization solutions such as silent upgrade and waterproof upgrade, along with supporting technical support and after-sales guarantee, to accurately match the personalized needs of different rehabilitation aids.
