A low-speed scooter refers to a three-wheel or four-wheel scooter used by the elderly with a speed of less than 10km/h. The elderly who are in good health and have strong self-care ability are reluctant to use a wheelchair and prefer to use a scooter. There is no essential difference between the two in terms of transmission and control, only a certain difference in structure. In addition, the three-wheel or four-wheel scooter with a speed of 11~20km/h is also used for general commuting because of its safety and comfort.
Typical scooter structure and technical parameters
Typical scooter structure and technology: The scooter can be three-wheeled or four-wheeled. Choose one with better technical parameters for analysis. Its power is 160W, and only one 24V/12A·h battery can run continuously for 2 hours. , that is, the continuation of 14km, the load capacity is relatively large, the center of gravity is very low, and the general seat can be rotated 90° in the plane, which is convenient for getting on and off and very safe. Generally, it can also be folded for easy carrying and put in the trunk of the car for use when going away.

Typical scooter structure details
Typical scooter structure and technology: the running and folded carrying status of the four-wheeled scooter, and its technical parameters and operation display panel are listed at the same time. The battery box and storage basket can be separated separately and can be folded together in the trunk of the car.
Ultra-light folding new electric scooter
A new type of ultra-light folding electric scooter. This car adopts lightweight materials and structural design, and the lithium battery is placed in the space of the car underframe. This one-piece design is very simple, fast and convenient to fold, and small in size. There is still room for two cars to be placed side by side in the trunk of the car.
Foldable double electric scooter
Two-seater foldable three-wheeled electric scooter. The mass of the car is 60kg without battery, but the price is not expensive. If equipped with a lead-acid maintenance-free 48V/20A·h battery, the vehicle weight will increase by 28kg; if equipped with a lithium battery of the same capacity, the price will increase accordingly, but the battery quality will be reduced by about 3/4, and the battery life can be increased by about 3/4. The running mode of the car can be double or single, and it can be folded and placed in the trunk of the car when going out for a long trip.

Newly developed electric and solar electric scooters
(1) New car structure. The above electric vehicles have been produced and sold by many companies, but the structure is complex, the quality is too large, and the price is relatively expensive. The production and sales of solar electric scooters are very few, so it is determined to develop a solar electric scooter with a simple structure, light weight and low price. In the design, a lightweight magnesium alloy hollow profile chassis and a stainless steel thin-walled square tube solar panel bracket are used to make the car body lightweight; a new type of electromechanical integrated electric wheel hub is used to further reduce the weight of the whole vehicle and simplify the transmission and operation mechanism of the whole vehicle; 120W solar energy is used. The electric vehicle driving energy combining the battery plate and the lithium-ion battery can increase the continuation time and prolong the battery life, and can be charged with less or even no utility power.

(2) The operation of the new car. The specification of the new car is DC 24V250W, and the weight does not exceed 10kg. It can be used as an electric load flat car, and with a folding chair, it becomes a scooter. During the trial operation, the riding experience is smooth and flexible, convenient and safe to go up and down, and easy to operate and control. Adding a bracket and a 100W solar panel becomes a solar electric vehicle. The solar panel and battery are combined to form a power supply system, which can extend the continuation time and battery life, and can also protect from wind and rain. The vehicle can be used for shopping and riding. The folding chair can be replaced by a cabinet storage box, which can be used for traveling, shopping, and small tools and instruments for external services. Shopping carts with seats can also be used, which can be easily upgraded to electric mobility shopping carts and solar electric mobility shopping carts. Refer to this structure, change the steel tube structure to aluminum alloy or magnesium alloy structure, and the wheels are driven by two 60W geared motors or Directly use two 60W in-wheel motors as running wheels, and use the controller to control its forward, backward, steering and running speed to become an electric scooter, and its weight will not exceed the original trolley. If you can add a thin-film solar battery umbrella, it will become a solar electric wheelchair, which can not only block the sun and rain, but also charge and charge your mobile phone by yourself.
(3) Comparison of new cars and existing ones. It is very easy to transform a commercially available electric scooter into a solar car, just install solar panels on the body, which is roughly the same as the newly developed solar car.
Newly designed combined solar electric travel shopping cart
Generally, wheelchairs and scooters are foldable to reduce volume and facilitate portability. The design adopts a combined type, which consists of three parts: a tractor, a lightweight flat car, and a solar umbrella. Together with different functional facilities, it can be used for various purposes. The components and connecting parts are standardized, so that each piece can be combined and used in multiple places. For example, the tractor can be used to tow various trolleys; the lightweight small flat car can be used as a manual flat car with a hand lever or an electric flat car with a tractor, and can also be further combined with a solar umbrella to form a solar electric car; It can be fixed separately in a certain place as a household charger.
