Seeing-eye cane

Abstract

The invention discloses a seeing-eye cane. The top end of a supporting rod is fixedly provided with a grip, the bottom end of the supporting rod is fixedly provided with two front supporting legs anda rear supporting leg, wherein the downward opening degree of the two front supporting legs at the front side of the cane is gradually increased, the rear supporting leg is located at the rear side ofthe cane and extends downward, the bottoms of the front supporting legs and rear supporting leg are fixedly provided with wheel frames respectively, the wheel frames are fixedly provided with rollers, the front end faces of the wheel frames on the two front supporting legs are fixedly provided with lower ranging radars, the lower ranging radars transmit front obstacle signals to a controller fixed in the grip through signal lines, the grip is internally and fixedly provided with a vibrator and a power source, the power source supplies power to the controller, and the controller outputs a vibration driving signal to the vibrator.

Description

technical field [0001] The invention relates to a cane with the function of guiding the blind. Background technique [0002] The existing ordinary cane for the blind can only guide the blind to walk by touching the ground, and cannot effectively remind the blind to avoid obstacles, nor can it realize real-time position monitoring of the blind. [0003] There are also canes with electronic detection functions, such as the patent title "An Intelligent Guide Cane for the Blind", the patent application number is 201711471348.9, which can reliably detect whether there is an obstacle in front by setting a sensor at the bottom of the cane and supporting the cane with wheels However, the sensors in this publication are concentrated at the bottom of the cane, the detection accuracy is limited, and the navigation and pointing functions cannot be truly realized. Contents of the invention [0004] The technical problem to be solved by the present invention is to realize a walking sti...

Problems solved by technology

[0002] The existing ordinary cane for the blind can only guide the blind to walk by touching the ground, and cannot effectively remind the blind to avoid obstacles, nor can it realize the real-time position monitoring of the blind. The function is relatively single and cannot meet the various travel needs of the blind.

[0003] There are also canes with electronic detection functions, such as the patent title "An Intelligent Guide Cane for the Blind", the patent application number is 201711471348.9, which can reliably detect whether there is an obstacle in front by setting a sensor at the bottom of the cane and supporting the cane with wheels objects, but the sensors in this publication are concentrated at the bottom of the cane, the detection accuracy is limited, and the navigation and pointing functions cannot be truly realized
