Safety blindbrick

Abstract

The invention belongs to the field of blind person guiding devices, and particularly relates to a safety blindbrick. The safety blindbrick comprises a shell. A brick body is slidingly connected into the shell in a sealed manner, vibration cavities are formed between the shell and the brick body, rings are fixedly connected to the side walls of the vibration cavities through springs, permanent magnets are embedded into the positions, corresponding to the rings, of the brick body, the rings are made of magnetic materials, the rings and the permanent magnets are in heterospolar attraction, four sliding grooves are formed in the brick body, the sliding grooves communicate with the vibration cavities through vent holes, convex blocks are slidingly connected into the sliding grooves through limiting mechanisms in a sealed manner, and the upper ends of the convex blocks stretch out of the brick body. When the walking route of a blind person deviates from a blind, the brick body slightly slides, alarm sound is sent through the rings, the blind person is reminded of correcting the route, dangerous accidents caused by the fact that the blind person deviates from the blind are avoided, the blind person can judge the turning directions of roads ahead according to the rotating directions of the convex blocks, and a good way guiding effect is achieved.

Description

technical field [0001] The invention belongs to the field of guiding devices for the blind, and in particular relates to floor tiles for safety blind passages. Background technique [0002] Blind pavement is a convenient road facility for blind people to travel safely. Generally, it is paved with three types of bricks, one is strip-shaped guiding bricks to guide blind people to move forward with confidence; the other is reminder bricks with dots to remind blind people that there are obstacles ahead; the other is blind road danger warning guiding bricks, The dots are larger. [0003] Most of the existing tactile floor tiles with round dots are simple in structure and can only play the role of simple guiding and prompting. When a blind person is walking, the route will inevitably have a slight deviation, but the blind person cannot perceive it at this time. This slight deviation will cause a large deviation during the accumulation process of a long road section, so that the ...

Problems solved by technology

[0005] The purpose of the present invention is to provide a safe tactile floor tile that can issue an alarm and remind blind people of the turning direction in view of the problem that the above-mentioned tactile turn cannot play a good warning and reminder role.
