Multifunctional blind guiding stick

Abstract

The invention discloses a multifunctional blind guiding stick, and relates to the technical field of walking sticks. The multifunctional blind guiding stick comprises a stick body and a handle, wherein the stick body is divided into an upper stick body and a lower stick body, a micro stepping motor is arranged at one end of the upper stick body, a rotating sleeve is fixed to an output shaft of the micro stepping motor, the output end of the micro stepping motor is fixed to the lower stick body through a bearing, the upper stick body and the lower stick body are connected through a U-shaped rod, and a detection radar is arranged on the outer surface of the rotating sleeve. According to the multifunctional blind guiding stick, when a control mainboard is arranged to be used in cooperation with the detection radar and a tilt angle sensor, in the using process, front road conditions can be reported at any time according to radar detection, the multifunctional blind guiding stick is more convenient to use, besides, precision is high, and the dead angle problem does not exist. In addition, by arranging the tilt angle sensor, family members can know the state of the user at any time, when the tilt angle of the tilt angle sensor reaches a certain range and exceeds a certain time, it can be judged that the user falls down, the family members can be automatically notified, and safety is higher.

Description

technical field [0001] The invention relates to the technical field of crutches, in particular to a multifunctional blind guiding stick. Background technique [0002] At present, the visually impaired people generally carry a guide stick with them, which is used to assist the visually impaired to walk. In the traditional technology, the guide stick is generally a wooden stick, through which the road conditions can be detected and the people with visual impairments can be assisted to walk. However, in the process of using the traditional blind guide stick, it only has the function of detecting the road surface, and the function is single. In addition, in the process of using, there are still a large number of dead spots for detection. The detection process is time-consuming and laborious, and it is very inconvenient to use. .
