Electric wheelchairs are portable and flexible mobility tools tailored for people with limited mobility, solving the outdoor shopping and errand problems that trouble the elderly and disabled groups for a long time. In daily life, purchasing vegetables, fruits, daily necessities and running simple errands are essential life needs. However, due to poor mobility, most elderly and disabled people can only wait for their family members to buy items on their behalf, which not only causes inconvenience to life, but also makes them lose the autonomy of life. Modern electric wheelchairs are designed with a narrow and flexible body, which can easily pass through narrow passages of supermarkets, vegetable markets and community shops. Equipped with stable driving performance, they can safely travel on urban commercial streets. Users can independently drive electric wheelchairs to nearby shopping places to complete daily shopping, select favorite goods and finish small errands such as picking up express delivery. This fully meets their daily life needs, helps them get rid of long-term dependence on others, and greatly improves the independence and convenience of daily life.
