Abstract
The invention discloses a wireless charge blind person obstacle-avoiding bracelet which consists of a wireless charge part and a bracelet part, wherein the wireless charge part consists of a charger and a wireless charge emitter; and the bracelet part consists of a wireless charge receiver, a battery and an obstacle-avoiding bracelet main board. The wireless charge blind person obstacle-avoiding bracelet disclosed by the invention is connected with the charger in a wireless manner, so that when being used by a blind person, the bracelet only needs to be placed on the wireless charge emitter, then the battery can be charged, and thus the problem that the battery is inconvenient to charge when the obstacle-avoiding bracelet is used by the blind person is avoided.
Description
Technical field
The present invention relates to a kind of blind person's articles for use field, particularly relate to a kind of wireless charging blind person's avoidance bracelet.
Background technology
Blind person's avoidance bracelet is a kind of assistant product of blind person's avoidance, but bracelet is a kind of electronic product, it is necessary to battery-powered, and owing to blind person can not look thing, has just become blind person to apply an obstacle of avoidance bracelet the charging of battery.
Summary of the invention
The present invention is to solve owing to blind person can not look thing, causes problem when using avoidance bracelet, battery charging is inconvenient, it is provided that a kind of wireless charging blind person's avoidance bracelet.
Be the technical scheme is that by realizing the purpose of the present invention
