I. Functional characteristics: break through height restrictions and enjoy a diverse experience
(I) Height adjustment, adapt to various scenarios
The most notable function of the electric lifting system is the ability to accurately adjust the height of the wheelchair. Whether it is dealing with different heights of ground differences in daily travel or matching the height of furniture facilities in various indoor environments, it can easily do the job. Outdoors, when encountering roadside steps, gentle slopes or uneven roads, users can raise the wheelchair to enhance passability and avoid being blocked by a low chassis. Indoors, facing furniture of different heights such as dining tables, desks, and sinks, users only need to operate the controller, and the wheelchair can quickly adjust to the appropriate height to achieve comfortable and convenient interaction. For example, when dining in a restaurant, raise the wheelchair to the same height as the dining table, so that users can naturally dine with their companions and no longer feel cramped due to height differences.
(II) Standing assistance, promoting physical and mental health
For many people with limited mobility, standing is a luxury, but the electric lifting system brings them hope. By raising the wheelchair to standing height, the user can simulate a standing posture, which not only helps improve the body's blood circulation and reduce the pressure of long-term sitting on the body, but also has a positive impact on mental health. The standing state allows users to view the world around them from a perspective closer to that of ordinary people, enhancing their self-confidence and sense of participation. From a rehabilitation perspective, moderate standing training is of great significance for maintaining bone density, strengthening muscle strength, and improving body balance. For example, during rehabilitation treatment, patients can use the standing function of the electric lifting wheelchair to conduct regular standing training under the guidance of a doctor to gradually restore their body functions.
II. Technical principle: precise construction to achieve smooth lifting
(I) Power drive: coordination of motor and transmission
The power source of the electric lifting system is usually a DC motor, and its stable and efficient power output provides reliable guarantee for the lifting of the wheelchair. The motor converts electrical energy into mechanical energy to drive the wheelchair to lift and lower through belt drive, screw drive or hydraulic drive. Belt drive has the characteristics of simple structure, low cost and smooth operation, which can meet general lifting needs. Screw drive is known for its high precision and high load capacity, and performs well when precise control of lifting height and heavy weight are required. Hydraulic drive, with its powerful thrust and stable pressure output, is suitable for scenarios with high requirements for lifting stability and speed. Driven by the motor, these transmission methods accurately control the lifting speed and height of the wheelchair to ensure the safety and stability of the entire process.
(II) Lifting structure: stable support, safe and reliable
The lifting structure is the core component of the electric lifting system. Common ones include scissor-type structure and sleeve-type structure. The scissor-type structure consists of multiple cross-connected connecting rods. During the lifting process, the connecting rods move in an interlaced manner, like scissors opening and closing, to achieve a smooth lifting action. This structure has the advantages of small footprint and high stability, and can provide a large lifting stroke in a limited space. The sleeve-type structure achieves height adjustment through multiple nested sleeves. Its design is simple, easy to maintain, and can withstand large vertical loads, providing solid support for the lifting of the wheelchair. Both the scissor-type and sleeve-type structures have been carefully designed and rigorously tested to ensure safe and reliable operation under various conditions.
(III) Control system: intelligent control, precise adjustment
The control system is like the "brain" of the electric lifting system, responsible for receiving the user's operating instructions and accurately controlling the operation of the motor and lifting structure. Modern electric lifting wheelchairs are usually equipped with advanced microcontrollers that can process the information fed back by various sensors in real time. For example, the height sensor can accurately measure the current height of the wheelchair and transmit the data to the control system so that it can be accurately adjusted according to the set target height. At the same time, the control system also has a variety of safety protection functions, such as overload protection and anti-fall protection. When it detects that the motor load is too large or an abnormal situation occurs during the lifting process, the control system will immediately take measures to stop the lifting action to ensure the safety of the user. Some high-end electric lifting wheelchairs also support wireless remote control operation. Users can conveniently control the lifting of the wheelchair within a certain distance through the remote control, which further improves the convenience of use.
III. Life Change: Expanding the Boundaries of Life and Regaining Confidence in Life
(I) Social Integration: Equal Communication, Eliminating Barriers
In social occasions, height differences often become an obstacle for people with limited mobility to communicate with others. The electric lifting system breaks this barrier, allowing users to keep eye contact with others in social activities and achieve truly equal communication. Whether attending a gathering with friends, a business meeting or a community event, users can confidently interact with people around them and integrate into the collective atmosphere by raising their wheelchair. This equal communication attitude not only helps to improve communication effectiveness, but also greatly enhances the user's social confidence, allowing them to regain the joy of freely interacting with others, expand their social circles, and better integrate into social life.
(II) Daily self-care: autonomous operation, enhanced dignity
In daily life, the electric lifting system significantly improves the user's self-care ability. To get items from high places, you no longer need the help of others. Users can raise their wheelchairs to easily reach them. When operating in the kitchen, you can adjust the wheelchair according to the height of the stove to cook. In the bathroom, you can also flexibly adjust the height of the toilet and sink to complete personal hygiene matters such as washing and cleaning. This ability to complete daily tasks independently greatly enhances the user's sense of self-identity and dignity, allowing them to feel more control and independence in life, no longer relying on others due to mobility problems, and truly realizing self-care.
