Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Example 1

Referring to fig. 1-2, an acousto-optic assisted traveling flexible sidewalk brick comprises a brick body 1, wherein an envelope body 2 is embedded on the brick body 1, a bar-shaped convex pattern 4 is integrally formed on the upper surface of the envelope body 2, the bar-shaped convex pattern 4 can help blind people distinguish blind sidewalk floor tiles from common pedestrian floor tiles and can play a role of skid resistance in rainy days, a circulation cavity 8 and a plurality of resonant cavities 16 are formed in the brick body 1, an L-shaped pipe 13 is communicated between each resonant cavity 16 and the circulation cavity 8, two sliding seats 10 are hermetically and slidably installed in the circulation cavity 8 through sliding grooves 11, bar-shaped magnets 9 are fixedly connected to opposite sides of the two sliding seats 10, two solenoids 12 are symmetrically arranged in the circulation cavity 8, a plurality of warning lamps 5 are installed on the upper surface of the brick body 1, each solenoid 12 is electrically connected with the corresponding warning lamp 5, a communicating pipe 3 is arranged between the envelope body 2 and the circulation cavity 8, and the tail end of the communicating pipe, after the capsule body 2 is extruded, the gas in the capsule body 2 enters the circulating cavity 8 through the communicating pipe 3 and pushes the two sliding seats 10 to slide along opposite directions;

each resonant cavity 16 comprises a vertical end and a horizontal end, a straight pipe 15 is communicated between the horizontal end of each resonant cavity 16 and the capsule 2, a hollow ball 7 is arranged at the vertical end of each resonant cavity 16 in a rolling mode, a plurality of balls 14 are arranged on the inner side wall of each resonant cavity 16, the hollow ball 7 is in contact with the balls 14, the balls 14 can change sliding friction between the hollow ball 7 and the inner wall of the resonant cavity 16 into rolling friction, friction force applied to the hollow ball 7 is reduced, and a tuning fork 6 is fixedly mounted at the horizontal end of each resonant cavity 16.

In this embodiment, the inner diameter of each straight tube 15 is smaller than the inner diameter of the corresponding L-shaped tube 13, so that when air flows from the inside of the L-shaped tube 13 to the straight tube 15, the gas flow rate at the upper part of the vertical end of the resonant cavity 16 is greater than the gas flow rate at the lower part thereof, and the pressures at the two parts are not equal.

Each bar magnet 9 and solenoid 12 are horizontally arranged, each bar magnet 9 is coaxial with the corresponding solenoid 12, and the relative positions of the bar magnets 9 and the solenoids 12 are changed along with the movement of the sliding seat 10.

When this embodiment uses, when the visually impaired person walks on the blind road, can trample utricule 2 on the brick body 1, and this pressure can make utricule 2 take place to deform, and its inside gas flows to circulation chamber 8 along communicating pipe 3 in and promotes two slides 10 to opposite direction, and along with the motion of slide 10, the relative position of bar magnet 9 and solenoid 12 changes, and the magnetic field of solenoid 12 department changes promptly, can know by Faraday's electromagnetic induction law: when a part of conductors of the closed circuit do motion of cutting magnetic induction lines in a magnetic field, induced current can be generated in the conductors, so that current can be generated in a closed loop formed by the warning lamp 5 and the solenoid 12, the warning lamp 5 can emit light, the closed loop further comprises a voltage stabilizing circuit, a current stabilizing circuit and the like, the part is the prior art and is not repeated herein, and therefore surrounding pedestrians are reminded of avoiding at night or under the condition of poor light, and the blind sidewalk is prevented from being occupied or colliding with a person with visual impairment;

when the sliding seat 10 slides to both sides, the air in the circulation chamber 8 is also squeezed into the resonant chamber 16, because the inner diameter of the straight pipe 15 is smaller than that of the L-shaped pipe 13, so the gas flow rate at the upper part of the vertical end in the resonant chamber 16 is greater than that at the lower part thereof, as can be known from bernoulli's principle: in water flow or air flow, if the speed is low, the pressure intensity is high, if the speed is high, the pressure intensity is low, the pressure intensities of the upper side and the lower side of the hollow ball 7 are unequal, and the pressure intensity above the hollow ball is lower than the pressure intensity below the hollow ball, so under the combined action of the gas buoyancy and the pressure intensity, the hollow ball 7 can move upwards until colliding with the tuning fork 6, and the sound emitted by the tuning fork 6 can help a vision-impaired person to distinguish the position of the person;

when the hollow ball 7 collides with the tuning fork 6, the tuning fork 6 vibrates and applies a downward force to the hollow ball 7, and at the same time, since the tuning fork 6 is located at the horizontal end of the resonant cavity 16, when gas flows from the vertical end to the horizontal end of the resonant cavity 16, due to the increase of the volume of the space, the gas flow rate at the horizontal end of the resonance cavity 16 will decrease suddenly (the gas flow rate at the adjacent end of the horizontal end and the straight tube 15 is still larger), therefore, the air pressure at the upper side and the lower side of the hollow ball 7 are approximately equal, the pressure does not push the hollow ball 7 to move any more, under the action of gravity and the tuning fork 6, the hollow ball 7 quickly falls down, when the hollow ball is close to the L-shaped pipe 13, the pressure difference generated by the airflow movement can drive the hollow ball 7 to move upwards, and the steps are repeated, when the capsule body 2 is extruded once, the hollow ball 7 can collide with the tuning fork 6 for many times, so that the vibration time of the tuning fork 6 is prolonged;

after entering the capsule body 2 from the straight pipe 15, the air flow can play a supporting role for the capsule body 2, and the deformation speed of the capsule body 2 is slowed down, so that the vision-impaired people can be prevented from having a 'step-on-empty' feeling;

when the visual disturbance person no longer tramples on utricule 2, utricule 2 resumes self shape, and the gas between two slide 10 reduces, and under the negative pressure effect, slide 10 can get back to initial position, and the gas distribution in the device also can resume initial condition.

Example 2

Referring to fig. 3, the present embodiment is different from embodiment 1 in that: arc sheetmetal 18 has been gone up the hot melt in the interior diapire of utricule 2, has a plurality of hollow short poles 17 through spring mounting on the interior roof of utricule 2, and the distance between every hollow short pole 17 and the interior roof of utricule 2 is the same all, and the material of hollow short pole 17 can be made for metals such as stainless steel, aluminum alloy to increase the sound loudness when hollow short pole 17 collides with arc sheetmetal 18.

When this embodiment uses, trample behind utricule 2 when the vision disorder person, the hollow quarter butt 17 that is located the middle part can strike arc sheetmetal 18 (arc sheetmetal 18 is upwards protruding, as shown in fig. 3), and both collisions can make a sound help the vision disorder person to discern the position, and hollow quarter butt 17 can take place vibrations and will shake in addition and transmit to utricule 2 by people's perception, even under noisy environment, the vision disorder person also can clearly oneself position.

Then, the gas enters the capsule body 2 from the straight pipe 15, under the action of the arc-shaped metal sheet 18, the gas flows upwards and blows the hollow short rods 17 on the two sides to move obliquely upwards, the upward air flow on one hand can increase the support on the upper surface of the capsule body 2, on the other hand, the hollow short rods 17 moving obliquely upwards collide with the hollow short rods 17 in the middle part, the vibration intensity and the sound loudness are increased, the vibration time of the side hollow short rods 17 can be prolonged through springs connected with the hollow short rods 17, and people with vision disorder can be guaranteed to hear the sound or feel the vibration.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
