[0002] With the improvement of living standards, people pay more and more attention to the travel safety of the elderly and the disabled, but ordinary crutches have single functions and cannot meet the living needs of contemporary people.

In order to realize that the guardian knows the position and situation of the elderly or the disabled at any time, and to carry out timely rescue of accidents, people have proposed a variety of smart crutches with positioning and calling for help, such as Chinese patents, application publication numbers: CN102920117A, CN203152739U and CN202222582U, these Crutches are powered by batteries, and cannot be used when the battery power is exhausted, and cannot be used for safety monitoring anytime, anywhere

At the same time, the frequent replacement of batteries brings a lot of inconvenience to the elderly and the disabled.

For the environment, waste batteries will also cause serious environmental pollution and waste of resources
