The control method of the electric scooter is the same as that of the traditional electric bicycle, which is easy to be learned by the driver. It is equipped with a detachable and foldable seat. Compared with the traditional electric bicycle, the structure is simpler, the wheels are smaller, and the wheels are lighter and simpler, which can save a lot of social resources. In recent years, the rapid development of lithium battery electric scooters has spawned new demands and trends.

Only in terms of software and hardware, it does not include the factors of the user and the use environment. Four key points affecting battery life: battery capacity, motor power, motor control method, and tires.
1) The battery of an electric scooter: The battery has the greatest impact on battery life. It is strongly recommended to buy a scooter that uses imported batteries. First, the battery conversion rate and energy density are higher, that is, the imported battery capacity is larger under the same volume and weight. At present, the single capacity of domestic batteries is 2000 or 2200, and the single capacity of imported batteries is 2600 or 3200, which is equivalent to 30% more battery life. The second is safe and secure. At present, there are too many examples of spontaneous combustion and explosion of scooter balance vehicles, all of which are caused by the use of inferior batteries.
2) Motor power of electric scooters: the greater the power, the better, there is too much waste, and too little is not enough. At the same time, the power selection of the hub motor is also related to the wheel diameter, speed, torque, and so on. Take a scooter with a wheel diameter of 8 inches as an example. The motor power can be in the range of 250W~350W. Each motor has an optimal power range. This is related to the output curve of the motor. The output power of the general cruising speed is just in this optimal range. inside.
3) Motor control mode of electric scooter: square wave control and sine wave control have their advantages and disadvantages. Swing wave control is comfortable, linear acceleration, high cost, low power consumption, and low sound. Square wave control is simple and rude, cheap and stable, accelerating straight, starting rush, cruising, and power saving. Generally, it is recommended to use sine wave control products. A good sine wave control product has higher requirements for the technical capabilities of the enterprise and pays more attention to the user experience. The overall energy utilization efficiency is 5 to 7% higher than that of square wave control.
4) The tires of electric scooters: the driving wheel has high friction and the driven wheel has low friction and high endurance, and vice versa.
Sine wave control is to turn the handle slightly under no load. At this time, the motor starts softly and smoothly and continues to accelerate to the highest speed. Under load, it starts softly without rushing, and there is no abnormal noise, quiet and comfortable; while the square wave controller is quiet and comfortable. When the handle is rotated a little under load, the motor will accelerate a little. Under load, there will be a lot of noise at the start, and the start is more aggressive, so it is not suitable to be manipulated.
The mainstream mobility scooter on the market has a two-wheel design, some of which are three-wheel designs (front three wheels or rear three wheels). Two-wheel design is recommended, which is flexible, safer in turning, cheap and reliable (the price of fewer wheels and suspension structure), Lightweight and compact. The wheel diameters are 4.5, 6, 8, 10, 11.5 inches, and the common ones are 6, 8, 10 inches. It is recommended to choose large wheel diameters, such as 8 inches and 10 inches, which have high safety passing and good steering. Because the smaller the wheels of the mobility scooter, the easier it is to fall when turning. There are 4 types of tires at the same time, solid tire, honeycomb solid tire, tube-type pneumatic tire, tubeless tire (tubeless pneumatic tire). It is not recommended to choose pneumatic tires for small wheel diameters. It is too easy to burst. It is recommended to choose pneumatic tires for 8 inches and above. The shock absorber through pneumatic tires does not require additional mechanical shock absorbers. Here is a point to note, pneumatic tires must be selected tires The width is more than 40, don't choose too narrow.
It is the responsibility of each manufacturer to produce mobility scooters that meet the standards, to ensure the safety of travel and the healthy development of the scooter market. Wisking healthcare Corporation. has conducted many tests on mobility scooters before they leave the factory, and the quality qualification rate is guaranteed.

Electric wheelchairs are used for patients with spinal injury and paralysis, brain injury and paralysis, general paralysis, the elderly, the infirm, and those with limited mobility. Patients need a lot of walking exercises to restore their health, increase the number of exercises and shorten the time of each exercise, prevent patients from falling left and right when sitting, and reduce the burden of patients’ family members and their pain. It is also an ideal means of transportation.

What is the difference between an electric wheelchair and a manual wheelchair?
How to choose a lightweight wheelchair?
Wheelchairs, as a means of transportation, can meet the needs of most people. However, users are often in a dilemma when choosing a wheelchair. Is it better to buy a manual or an electric one? Below, I will introduce the difference between a manual wheelchair and an electric wheelchair, hoping to help buyers.
Both use the same function: both are means of transportation for people with limited mobility.
The difference between an electric wheelchair and a manual wheelchair is that the electric wheelchair has an intelligent control controller. electric wheelchairs can walk automatically by manipulating the controller, and manual wheelchairs must be driven by humans to walk.
The two have different requirements for users: manual wheelchairs have no specific requirements for patients. If the patient is unable to manipulate it, it can be driven by the help of others; electric wheelchairs have certain requirements for patients, requiring users to be sane and able to operate by themselves. There is a big difference between the price of an electric wheelchair and a manual wheelchair, and an electric wheelchair of the same model is much more expensive than a manual wheelchair.
Many people pick and choose lightweight wheelchairs, and they are always afraid that they will be difficult to use and inappropriate, and it will be troublesome to return and exchange products.
Lightweight wheelchairs are medical devices, and their structure is much more complicated than manual wheelchairs. Many people will feel big when they see a bunch of terms such as brush motors and lithium batteries. You don't need to be obsessed with various professional terms. Today, I will briefly talk about three points to help you choose a suitable electric wheelchair.
1. Security. The elderly and the disabled themselves have limited mobility, and use electric wheelchairs to ensure safety is the priority. The safety design of electric wheelchairs mainly includes anti-backward wheels, seat belts, anti-skid tires, electromagnetic brakes, and differential motors.
2. Comfort. Safety is a must for all lightweight wheelchairs. Comfort mainly refers to the seat system of the wheelchair, which involves the seat width, cushion material, backrest height, and so on. It’s best if you have the conditions for a test drive. It doesn’t matter if you don’t have a test drive. Unless you have a very special physical condition and have special requirements for size, the general size can meet your needs. Cushion material and backrest height, general sofa chair + high backrest are the most comfortable, and the corresponding weight will increase! So consider it according to your ideas.
3. Portability. Portability is the most important point linked to personal needs. Lightweight wheelchairs are generally convenient to fold and store, and the weight is controlled within 30kg; functional wheelchairs and long-endurance wheelchairs are relatively heavy and have low portability.
Wisking healthcare Corporation has developed many electric wheelchairs and conducted extensive tests before leaving the factory to ensure quality. Wisking healthcare Corporation. is committed to selecting high-quality fabrics, a professional design and production team, and integrating cutting-edge technology into product development, just to create perfect, trustworthy, and exquisite products.

There are many types of electric wheelchairs on the market. According to the material, they can be divided into the aluminum alloy, light material, and steel. For example, according to the type, it can be divided into ordinary wheelchairs and special wheelchairs. Special electric wheelchairs can be divided into leisure sports wheelchair series, electronic wheelchair Series, seat-side wheelchair series, standing-aid wheelchair series, etc. The electric wheelchair is equipped with anti-forward and anti-backward small wheels. The 8-wheel configuration ensures safe to use when standing and going uphill. It adopts the latest international top-level control system, fully automated, five-speed transmission, a maximum speed of 12KM per hour, and 360° arbitrary steering (front, rear, left, and right) Walk freely). Simple structure, strong power, electromagnetic brake (automatic braking when parking, parking on half slope).

●What are the common failures of electric wheelchairs?
When buying a lightweight wheelchair, pay attention to the seat width: measure the distance between the hips or between the two strands when sitting down. After adding 5cm, 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, but the hip and thigh tissues are compressed; the seat is too wide, it is difficult to sit firmly, it is inconvenient to operate the wheelchair, the limbs are easy to fatigue, and it is difficult to enter and exit the gate. Seat length of an electric wheelchair: Measure the horizontal distance from the hip to the calf gastrocnemius when sitting down, and reduce the measurement result by 6.5cm. If the seat is too short, the weight will mainly fall on the sit bones, which will easily cause excessive local pressure; if the seat is too long, it will compress the popliteal area and affect the local blood circulation, and it is easy to irritate the skin. For patients with short thighs or flexion contractures of the hips and knees, it is better to use a short seat. The seat height of a lightweight wheelchair: measure the distance from the heel (or heel) to the popliteal socket when sitting down, plus 4cm. When placing the pedals, the board should be at least 5cm above the ground. If the seat is too high, the wheelchair cannot enter the table; if the seat is too low, the seat bones will bear too much weight. The seat cushion of electric wheelchair In order to be comfortable and prevent bedsores, a seat cushion should be placed on the chair of the wheelchair. Common cushions are foam rubber cushions (5-10cm thick) or gel cushions. To prevent the seat from sinking, a 0.6cm thick plywood can be placed under the cushion.
Electromagnetic brake of lightweight wheelchair: It can only break when it is electric. Always pay attention to whether the tire pressure of the electric wheelchair is normal. This is the most basic. Wash the chair cover and leather backrest of the electric wheelchair with warm water and diluted soapy water. Always use a lubricant to maintain the electricity, but don't use too much to prevent the oil stains from staining the floor. Maintain general maintenance from time to time, and check whether the screws and screws are secure. Please use clean water to wipe the body of the car normally, avoid placing the lightweight wheelchair in a damp place and avoid knocking on the controller, especially the rocker; when carrying the electric wheelchair, please protect the controller strictly. When the controller is contaminated by food or beverages Please clean up immediately, use diluted cleaning fluid dampened with a cloth to wipe, avoid using abrasive or alcohol-based cleaning agents.
The battery of a lightweight wheelchair is the key to driving. The battery of high-end electric wheelchairs has a relatively high price in the market. Therefore, in the process of using electric wheelchairs, battery maintenance is very important. The problem that the battery is prone to be that there is no way to charge and it is not durable after charging. First, if the battery cannot be charged, check whether the charger is normal, and then check the fuse. Small problems basically occur in these two places. Secondly, the battery is not durable after charging, and the battery is worn out during normal use. Everyone should know this; the battery life will gradually weaken over time, which is normal battery loss; if it occurs suddenly Endurance problems are generally caused by the excessive discharge. Therefore, in the process of using the electric wheelchair, the battery must be diligent in maintenance. In the control parts of the lightweight wheelchair, the brake is a very important part, which is closely related to the personal safety of the user. Therefore, every time you use an electric wheelchair, you must check whether the brakes are normal. The reason why the brakes often fail is caused by the clutch and the rocker. Every time you travel with a lightweight wheelchair, check whether the clutch is in the "gear ON" position, and then check whether the rocker of the controller bounces back to the middle position. If it is not for these two reasons, it is necessary to consider whether the clutch or controller is damaged, then repair it in time, and avoid using a lightweight wheelchair when the brake is damaged.
Do you know where to buy qualified electric wheelchairs? Each manufacturer has the responsibility to produce electric wheelchairs that meet the standards to ensure the safe travel of the disabled. Before leaving the factory, Wisking healthcare Corporation conducted a large number of connection tests on the electric wheelchairs to ensure the quality assurance rate.

Mobility scooter instead of walking is a lot of people buy a car first, when the two cars in the home, or because the license plate, restrictions or other factors, such as the travel distance is not far away, convenient family charging conditions. The electric car instead of walking becomes the first choice, and low-speed electric cars because the price is cheap, convenient and easy driving became a lot of people choose, but there are also some new products. So is the elderly scooter a compliant electric scooter? If not, how do you build a qualified mobility scooter in this segment of the market, and what are the minimum standards it should meet? Will more brands and models be entering this market in the future? Let's take a look.
Here is the content list:
● What are the functions of the mobility scooter？
● Do you know about mobility scooters for the elderly?
● Do you know handicap scooter？
The two clamp-shaped handlebars on the handlebars of the elderly mobility scooter are equipped with contact switches. When braking, the switch is pushed to close or be disconnected, and the original switching state is changed. This change forms a signal that is transmitted to the control circuit, which, according to the preset program, sends out instructions to immediately cut off the base drive current, cutting off the power and stopping the power supply. Therefore, both the power tube itself and the old motor are protected, and the waste of power supply is prevented. Electric scooters also have voltage protection. Discharge termination voltage protection refers here to the voltage of the supply. When the discharge final stage, in the load state, the power supply voltage has been close to the "discharge termination voltage", the controller panel (or instrument display panel) that shows the lack of power, attracting the attention of cyclists, plan their journey. When the power supply voltage has reached the end of discharge, the voltage sampling resistor will feed the shunt information into the comparator.
Strictly speaking, the real mobility scooter products for the elderly should be evolved from the electric wheelchairs originally belonging to medical devices, and the design of the product is more suitable for the driving habits of the elderly and the disabled. Moreover, it applies to disabled people from the original electric wheelchairs to the elderly people with difficulty in legs and feet. Product design and production of all reference to the national standard of national electric bicycle and electric wheelchairs national standards, in terms of some parameters in the above two or even more strict national standards, design within 10 km/hour speed, vehicle chassis height in 8 cm, braking distance, within 0.5 meters from the various aspects are better than the original electric wheelchairs, It is an evolutionary and upgraded model of electric wheelchairs, which can meet the needs of elderly friends for travel, and provide more comprehensive safety protection.
With the faster and faster pace of the city, more and more people choose mobility scooters and balance vehicles in the process of travel. Because of their small size, low cost, and convenient use, handicapped scooters greatly facilitate People's Daily travel. The handicapped scooter also appeared on the market, which can also be used by the disabled, greatly improving the quality of people's life.
It is the responsibility of each manufacturer to produce standard mobility scooters to ensure the healthy development of the mobility scooter market. Wisking healthcare Corporation tests the connections of its scooters several times before they leave the factory to ensure they are up to standard.
