　　It also expounds what kind of life the electric wheelchair can improve for the disabled and the elderly, and probes into its positive influence on the life of the disabled, hoping to encourage the disabled and people with mobility difficulties to actively and confidently use reasonable tools to help them improve their quality of life.

　　Since the 1990s, the mechanical design of wheelchair has basically been finalized, and it has made great progress mainly in the scientific and technological content, and has become a completely customizable small vehicle. For example, the famous physicist Hawking’s wheelchair has a built-in computer so that Hawking can control the wheelchair independently.

　　The origin of electric wheelchairs can be traced back to the early 20th century. The earliest electric wheelchair was invented by Canadian engineer George Klein, who designed an electric wheelchair to help soldiers who lost their walking ability because of disability during World War II. Clay’s core design is still the design basis of electric wheelchair because the wheelchair is endowed with more comprehensive functions. Although this kind of electric wheelchair is relatively heavy, it provides a way for the disabled to move independently and greatly improves their quality of life.

　　With the progress of science and technology, the design and technology of electric wheelchairs are constantly improving. In the 1960s, electric wheelchairs began to use rechargeable batteries, which made them last longer and charge more conveniently. In the 1970s, the materials and structures of electric wheelchairs began to be improved, making them more portable and stable. In 1980s, with the development of computer technology, intelligent control system was introduced into electric wheelchairs, which made the wheelchairs operate more accurately and the user experience better. In addition, the battery technology of electric wheelchairs has also made a revolutionary breakthrough.period 輪椅 Many adjustments have also been made, and the direction of product research and development has been reversed, in order to better meet the market demand. https://www.hohomedical.com/collections/wheelchair

　　The traditional lead-acid battery is gradually replaced, and the new lithium battery and fuel cell technology are applied to electric wheelchairs, which greatly improves the endurance and service life of wheelchairs. These technological innovations not only make electric wheelchairs more environmentally friendly, but also provide users with longer use.

　　The types of electric wheelchairs are becoming more and more abundant. According to different functions and usage scenarios, electric wheelchairs can be divided into indoor electric wheelchairs, outdoor electric wheelchairs, folding electric wheelchairs and many other types. Indoor electric wheelchairs are usually small and suitable for use in indoor environments, such as homes and hospitals.

　　Outdoor electric wheelchairs are more powerful, have better passability, and are suitable for outdoor complex road conditions. The folding electric wheelchair is portable and can be carried and stored conveniently. Modern electric wheelchairs use lightweight aluminum alloy frames, intelligent control systems and high-performance batteries. The application of these technologies makes the electric wheelchair more intelligent, convenient and comfortable.

　　Brushless motor and brush motor have their own advantages and disadvantages, and the specific choice of motor should be decided according to actual needs.with 輪椅 For example, if it continues to develop, it will definitely become the benchmark of the industry and play an important role in leading the market. https://www.hohomedical.com/collections/wheelchair

　　Brush motor is a common motor used in early electric wheelchairs. Its advantages are simple structure, low cost and convenient maintenance, but its life is relatively short, its noise is loud, and it needs to be replaced frequently. Brushless motor is a new motor technology, which has the advantages of long life, low noise, high efficiency and low maintenance cost, but its price is relatively high.

　　Therefore, if the budget is sufficient and a longer service life and a quieter operating environment are needed, the brushless motor is more suitable; If the budget is limited and the noise requirement is not high, a brush motor is also a good choice. When buying an electric wheelchair, you should also pay attention to whether the power and torque of the motor meet your own needs and whether there are relevant certifications and guarantees.

　　Is the electric wheelchair as long as possible?

　　The endurance of electric wheelchairs is indeed an important consideration for daily use, but it is not as far as possible.

　　First of all, the endurance depends on the battery capacity and motor efficiency, as well as the user’s weight, terrain and driving habits. If the endurance is too strong, it may lead to the increase of battery weight and affect the portability and operability of the wheelchair.

　　Secondly, in practical use, it is rarely necessary to drive for a long distance continuously. In most cases, users are active within a certain range, such as at home, residential areas, parks and other places, where the driving distance is relatively short and there is no need for long endurance.

　　Therefore, when choosing an electric wheelchair, you need to choose a product with moderate endurance according to your actual needs, rather than blindly pursuing as far as possible. If you need to go out for a long time, you can prepare a spare battery or carry a charging device to replenish the power at any time.

　　Is the electric wheelchair a lead-acid battery or a lithium battery?

　　Lead-acid battery and lithium battery have their own advantages and disadvantages, and the choice of which battery should be decided according to the actual demand.

　　Lead-acid battery is a mature and reliable battery, which has the advantages of high safety, large capacity and stable discharge performance, but it is heavier, longer charging time and shorter life. Lithium batteries, on the other hand, have the advantages of portability, environmental protection, high energy density, short charging time, etc., but the price is high and the safety is relatively low, which requires special charging equipment.

　　Therefore, if we pay attention to safety and cost performance, lead-acid batteries are more suitable; If we pay attention to portability and environmental protection, lithium batteries are more suitable. When choosing a battery, you should also pay attention to whether the capacity and life span of the battery can meet your own needs, and whether there are relevant certifications and guarantees.

　　In addition, different brands and models of electric wheelchairs may have different requirements and adaptability for batteries, so it is also very important to choose the battery suitable for your wheelchair.

　　Wheelchairs are widely used in patients’ rehabilitation training and family life, such as lower limb dysfunction, hemiplegia, paraplegia below the chest and people with mobility difficulties. As patients’ families and rehabilitation therapists, it is very necessary to know the characteristics of wheelchairs, choose the most suitable wheelchairs and use them correctly.If we can practice these points, 輪椅 Will be unique, become a leader in the industry, and keep moving forward. https://www.hohomedical.com/collections/wheelchair

　　First of all, what harm will an inappropriate wheelchair do to the user?

　　Excessive local compression

　　Form a bad posture

　　Induced scoliosis

　　Causing contracture of joints

　　(What are the unsuitable wheelchairs: the seat is too shallow and the height is not enough; The seat is too wide and the height is not enough)

　　The main parts that wheelchair users bear pressure are ischial tubercle, thigh, popliteal fossa and scapula. Therefore, when choosing a wheelchair, we should pay attention to whether the size of these parts is appropriate to avoid skin wear, abrasions and pressure sores.

　　Let’s talk about the choice of wheelchair, which must be kept in mind!

　　Choice of ordinary wheelchair

　　Seat width

　　Measure the distance between two hips or between two legs when sitting down, and add 5cm, that is, there is a gap of 2.5cm on each side after sitting down. The seat is too narrow, it is difficult to get on and off the wheelchair, and the hip and thigh tissues are compressed; The seat is too wide, it is difficult to sit still, it is inconvenient to operate the wheelchair, the upper limbs are easy to get tired, and it is difficult to get in and out of the gate.

　　Seat length

　　Measure the horizontal distance from the hip to the gastrocnemius of the calf when sitting down, and reduce the measurement result by 6.5cm. The seat is too short, the weight mainly falls on the ischium, and the local pressure is easy to be too much; If the seat is too long, it will compress the popliteal fossa, affect the local blood circulation, and easily irritate the skin of this part. It is better to use a short seat for patients with extremely short thighs or flexion and contracture of hips and knees.

　　Seat height

　　Measure the distance from the heel (or heel) to the popliteal fossa when sitting down, and add 4cm. When placing the pedal, the board surface should be at least 5cm from the ground. The seat is too high for the wheelchair to enter the table; The seat is too low and the ischium bears too much weight.

　　seating washer

　　In order to be comfortable and prevent pressure sores, a seat cushion should be placed on the seat, and foam rubber (5~10cm thick) or gel cushion can be used. To prevent the seat from sinking, a piece of plywood with a thickness of 0.6cm can be placed under the seat cushion.

　　Backrest height

　　The higher the backrest, the more stable it is, and the lower the backrest, the greater the range of motion of the upper body and upper limbs. The so-called low backrest is to measure the distance from the seat surface to the armpit (one arm or two arms extend forward horizontally), and subtract 10cm from this result. High backrest: measure the actual height from the seat surface to the shoulder or back pillow.

　　Handrail height

　　When sitting down, the upper arm is vertical and the forearm is flat on the armrest. Measure the height from the chair surface to the lower edge of the forearm, and add 2.5cm. Proper armrest height helps to maintain correct posture and balance, and can make the upper limbs placed in a comfortable position. The armrest is too high, and the upper arm is forced to lift up, which is easy to fatigue. If the armrest is too low, you need to lean forward to maintain balance, which is not only easy to fatigue, but also may affect your breathing.

　　Other auxiliary parts of wheelchair

　　Designed to meet the special needs of patients, such as increasing the friction surface of the handle, extending the brake, anti-shock device, anti-skid device, armrest mounting arm rest, wheelchair table to facilitate patients to eat and write, etc.

　　In rapidly evolving industrial environments, a stable, intelligent, and power-efficient network backbone is critical. That¨s where the 8-port L2+ industrial managed PoE switch becomes indispensable. Designed specifically for rugged deployments like factory floors, outdoor surveillance systems, and transportation networks, this type of switch combines Power over Ethernet (PoE) with advanced Layer 2+ network management features to simplify infrastructure and enhance performance.Therefore, this is the choice Industrial Switch manufacturers The reason, there is no denying its positive impact. https://yuhangswitch.com

　　Understanding the Role of an 8-Port PoE Switch in Industrial Networks

　　An 8 port PoE switch provides both data and electrical power through a single Ethernet cable, reducing the need for separate wiring. In industrial scenarios, this helps eliminate complex cabling layouts, especially when deploying IP cameras, access points, or sensors in difficult-to-reach areas.The 8-port configuration strikes a balance between cost-efficiency and scalability. It¨s ideal for edge-level deployment in distributed networks, small control panels, or localized device clusters. In automation lines, for example, an 8-port switch can connect PLCs, sensors, and surveillance cameras with centralized management and real-time visibility.

　　What Makes It ＾L2+￣?

　　The term L2+ PoE switch refers to a Layer 2 switch with certain Layer 3 capabilities, such as static routing, VLAN segmentation, DHCP snooping, IGMP snooping, and enhanced QoS. This makes L2+ switches smarter than basic unmanaged or L2-only switches, allowing for more advanced network control and traffic segmentation. For industrial uses, the benefits of L2+ switching are significant. It enables operators to isolate traffic between machine groups or departments, prioritize real-time data like video feeds, and maintain high security across distributed environments. For example, in a smart factory with dozens of machines and sensors, VLANs help ensure clean traffic flow while preventing cross-device interference.

　　industrial switch.JPG

　　Industrial Features That Matter

　　An industrial managed PoE switch is not the same as a commercial or office-grade switch. It¨s built to operate in wide temperature ranges (e.g., -40＜C to +75＜C), withstand vibration and shock, and support DIN-rail mounting for control cabinets. Redundant power inputs and surge protection are also standard, ensuring 24/7 uptime in mission-critical systems.

　　Such switches are typically found in the following industries:

　　Manufacturing & Automation: For machine-to-machine communications, sensor networking, and HMI device connection.

　　Smart Cities: Connecting IP cameras, traffic control systems, and wireless APs at street level.

　　Energy & Utilities: In substations and remote monitoring setups with high environmental stress.

　　Transportation: In railway stations, tunnels, or roadways where robust and compact design is essential.

　　Why PoE with SFP Uplinks?

　　A PoE switch with SFP (Small Form-Factor Pluggable) ports provides added flexibility. While the regular RJ45 ports are used to power and connect IP devices, the SFP ports serve as high-speed fiber uplinks for long-distance transmission. In industrial settings, this ensures uninterrupted communication between remote cabinets or across large-scale plants. For example, if a control room needs to connect to another building 2km away, using a fiber SFP module eliminates the need for expensive long-range Ethernet cabling and ensures greater transmission integrity. The combination of PoE and SFP uplinks also helps build hierarchical network architectures where edge switches aggregate traffic to core switches or network video recorders (NVRs).

　　Centralized Control and Security with Managed PoE

　　The key advantage of an industrial managed PoE switch is control. Network administrators can remotely monitor each port, enable or disable power, assign bandwidth limits, and receive SNMP alerts in real time. This is especially important for industrial IoT applications where uptime and resource allocation need to be tightly regulated. Security features like port isolation, 802.1X authentication, ACLs, and MAC filtering further ensure that only authorized devices can access specific network zones. This is crucial in facilities where cybersecurity is as important as physical safety.
