Description

Scooter for old people

Technical Field

The utility model belongs to the technical field of the car of riding instead of walk, concretely relates to car of riding instead of walk old age.

Background

Since the 21 st century, the aging problem of the population is increasingly serious, the traveling problem of the old is increasingly prominent, and walking is one of important activities in daily life for the aging population, and is also considered to be an economic, safe and free activity mode. The physical aging of the group caused by various reasons such as diseases and age causes difficulty in going out, is difficult to exercise for outdoor activities, does not solve the problem of people without the aid of tools, and needs a walking machine to complete corresponding living activity requirements.

At present, domestic scooter is divided into three-wheel scooter and four-wheel scooter, and the used controller and electromagnet and brake are all from abroad, so that the cost is high. In addition, there are two rounds of riding instead of walking, which is based on a basic principle called dynamic stability, namely the automatic balancing capability of the vehicle. The posture state of the vehicle body is judged by a built-in precise solid-state gyroscope, and after a proper command is calculated by a precise and high-speed central microprocessor, a motor is driven to achieve the effect of balance. The general scooter for old people consists of four parts, including accumulator, electric hub, controller and charger, and body.

The existing walking machine mainly has the following problems: the safety and maneuverability are not high when the vehicle is in various complex road conditions such as bumpiness and the like and is difficult to move; the volume is large, and the requirement on the use field is met; the height of the seat is not easy to adjust, and the riding comfort is easily influenced; the chassis is high and light, and is easy to overturn: as is well known, the gravity center of a vehicle with a low chassis is low, the vehicle is stable during running, and the vehicle is not easy to overturn. On the contrary, a vehicle having a high height above the ground has a high center of gravity, and thus has poor safety during traveling. Particularly, when the vehicle runs at high speed, the vehicle is easy to fly and turn over; the brake component is thin and easy to damage, the internal circuit is poor in quality, rough and messy, and spontaneous combustion is easy; the axle structure is unreasonable: the wheel axle is typically of an axle-type design. Due to the design, the whole wheel track is small, and the side turning is easy. Meanwhile, the axle is exposed, so that articles are easily dragged and are extremely unsafe.
