Detailed Description

The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

As shown in figures 1-5, a device for facilitating the walking of the blind at night and a using method thereof comprise a blind road 1 and a blind stick 2 which are matched with each other.

The blind sidewalk 1 comprises a support piece 3 as a main body of the blind sidewalk 1, and a plurality of vertically arranged moving grooves 4 are arranged in the support piece 3.

As shown in fig. 2 and 3, the two opposite side walls of the moving slot 4 are fixedly connected with fixing pieces 5, the two fixing pieces 5 are permanent magnets, and the magnetic poles on the opposite sides of the two fixing pieces 5 are oppositely arranged.

The bottom end of the moving groove 4 is fixedly connected with a first spring 6, the top end of the first spring 6 is fixedly connected with a moving part 7, and a coil 71 which can be matched with the fixing part 5 is arranged in the moving part 7.

When the moving member 7 moves up and down, the coil 71 in the moving member 7 cuts the magnetic induction line, so that induced current is generated in the coil 71.

The moving member 7 is provided with a light emitting mechanism 8, and the light emitting mechanism 8 is composed of a power supply 81, a warning light 82 and a voice-operated delay switch 83.

The power 81 is charged by the coil 71, the power 81, the warning light 82 and the voice-operated delay switch 83 are all arranged in series, after the voice-operated delay switch 83 is closed, the warning light 82 can be automatically closed after working for a period of time, and the moving member 7 is located above the warning light 82 and is of a transparent structure.

The supporting piece 3 is internally provided with a trigger mechanism 9 for controlling the light-emitting mechanism 8 to work, and the state of the trigger mechanism 9 is controlled by the blind stick 2.

As shown in fig. 4, the trigger mechanism 9 is composed of a trigger chamber 91, a slide plate 92, a second spring 93, and a whistle 94.

Trigger chamber 91 and set up in support piece 3, and sliding plate 92 is sealed sliding connection in triggering chamber 91, and both ends are respectively with sliding plate 92 bottom and trigger chamber 91 top fixed connection about second spring 93, and whistle 94 fixed connection just triggers chamber 91 intercommunication setting at the chamber 91 diapire and with triggering chamber 91.

A conduit 95 is arranged in the support 3, and the conduit 95 is used for communicating the bottom end of the whistle 94 with the top end of the trigger cavity 91.

The pipe 95 can realize that the inside of the trigger mechanism 9 is in a relatively sealed environment, so that the situation that the whistle 94 is blocked by foreign matters after being used for a long time can be avoided.

The sliding plate 92 is provided with a permanent magnet, and the bottom end of the blind stick 2 is provided with a ferromagnetic substance which can enable the sliding plate 92 to move up and down.

When the blind stick 2 approaches the blind road 1, a magnetic attraction force is generated between the sliding plate 92 and the blind stick 2, so that the sliding plate 92 moves upwards, the airflow flows through the whistle 94 in the upward direction, and the whistle 94 emits sound waves with specific frequency.

The closing of the voice-activated delay switch 83 is controlled by the particular frequency of sound emitted by the airflow as it passes through the whistle 94.

When the blind sidewalk is used, when a pedestrian steps on the blind sidewalk 1, the pedestrian can step down the moving member 7, after the pedestrian leaves, the moving member 71 can reset under the action of the first spring 6, and in the process, the coil 71 in the moving member 7 can cut the magnetic induction line to charge the power supply 81.

And then the realizing device need not external power just can realize work, and wherein the component is all inside moving member 7, does not have the contact etc. that exposes in the external world for the inside component of moving member 7 can have fine leakproofness, and then realizes that the component in moving member 7 will have longer life.

And the moving part 7 capable of moving up and down has more obvious touch feeling, so that the blind can sense the position of the blind road more accurately.

When the blind person walks on the blind road 1, the blind person can use the blind stick 2 to go round, and when the blind stick 2 is contacted with the blind road 1, the sliding plate 92 close to the blind stick 2 can generate magnetic attraction with the blind stick 2.

The blind person can more accurately sense the position of the blind road 1 through the magnetic attraction, the sliding plate 92 can move upwards through the magnetic attraction, and then the gas of the triggering cavity 91 positioned at the top end of the sliding plate 92 can enter the lower part of the sliding plate 92 through the conduit 95 and the whistle 94.

At this moment, the whistle 94 can emit sound waves with specific frequency, the sound control delay switch 83 can be closed under the action of the sound waves with the specific frequency, the warning lamp 82 can start to work, the warning lamp 82 can play a role in reminding, and common pedestrians and blind people can be distinguished through the blind stick 2.

When the blind person walks, the blind person can clearly perceive the position of the blind road 1 through the touch of the moving part 7 and the touch of the blind stick 2, and the blind person can walk on the blind road 1; meanwhile, the blind road 1 emits sound waves with specific frequency and the warning lamp 82 emits light, so that surrounding pedestrians are reminded of walking on the blind road 1 together and paying attention to avoidance of the blind persons.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
