Automatic brake gear used for walking aid

Abstract

The invention discloses an automatic brake gear used for a walking aid and belongs to the technical field of walking aids. The automatic brake gear comprises an infrared sensor circuit, an audion switching circuit, a power supply and two electromagnetic brakes. The automatic brake gear can use an infrared sensor to sense the distance between a walking aid user and the walking aid. When the distance is within a certain range, the walking aid normally walks, and the brakes are not triggered. When the distance exceeds the certain range, the walking aid is judged to abnormally walk, the user is not near the walking aid, and the automatic brake is immediately triggered, thus the walking aid is braked to be locked so as to prevent accidents.

Description

technical field [0001] The invention relates to a device in the technical field of walking aids, in particular to an automatic braking device for walking aids. Background technique [0002] At present, the total number of elderly people over the age of 60 in the world has reached 600 million, and the elderly population in more than 60 countries has reached or exceeded 10% of the total population, and they have entered the ranks of population aging societies. The rapid development of population aging has aroused the attention and concern of the United Nations and governments around the world. According to a report released by the Chinese Academy of Social Sciences not long ago, by 2030, China will become the country with the highest aging population in the world; by 2050, Chinese society will enter a stage of deep aging. The increase in the proportion of the elderly population means that the proportion of young people who take care of the elderly will decrease, and the task ...

AI Technical Summary

Problems solved by technology

The walking aids currently on the market generally use mechanical brake systems. When braking or locking the walking aids, the elderly need to operate the brakes by hand.

The elderly have poor memory. In some situations, such as downhill terrain, when the elderly need to stop and talk to others, the elderly forget to set the brake or lock the walker.

At this time, the walker will slide away automatically, which may cause serious personal injury and property damage

[0003] After searching the prior art, it is found that Chinese patent document number: CN200987758Y, name: walking aid brake device, Chinese patent document number: CN2431185Y, name: walking aid brake, Chinese patent document number: CN2365125Y, name: walking aid brake device and Chinese patent document number: CN2283476Y, name: a brake for a walker, these four inventions have introduced brake devices for a walker with different structures, but the brake devices for a walker involved in these inventions all belong to Manual mechanical brake, so when you need to brake or lock the walker, you need the old man to operate the brake by hand
