Most one of the country of world blind person, eye disease are also a main public health problem in China.There are about blind persons for China
600-700 ten thousand accounts for the 18% of world blind person sum, separately there is eyes low visual acuity patient 12,000,000.Blind person is both our common people
In a member, and be a specific group, they are since congenital or posteriori physiological defect is in daily life than our ordinary persons
More inconveniences can be encountered, cannot accurately and timely find and avoiding barrier is exactly an important drawback.
Utility model content
The purpose of this utility model be exactly in order to overcome the problems of the above-mentioned prior art and provide a kind of structure it is simple,
Can effectively avoiding barrier intelligent blind-guiding crutch.
The purpose of this utility model can be achieved through the following technical solutions: a kind of intelligent blind-guiding crutch, including the body of rod
And handle, the bottom of the body of rod are equipped with sensor box vertical with the body of rod and for incuding front obstacle, the sensor
The both ends of box are equipped with idler wheel.The utility model can incude the barrier in front by sensor box, and inform blind person, avoid blind
People knocks barrier.In addition, adapt to various terrain environments due to being provided with idler wheel, be not in common crutches by stitch, protrusion
The case where object is stuck, abrasion.
In the sensor box equipped with ultrasonic range finder, the processor being connect with ultrasonic range finder and with processing
The front end of the voice alerting unit of device connection, the sensor box is equipped with multiple windows, and the ultrasonic range finder is placed on it
In a window rear.Ultrasonic sensor can issue forward a ultrasonic signal, which returns after encountering barrier
And received by ultrasonic sensor, processor calculates the distance of barrier, and processing result is then issued voice alerting unit, accuses
Knowing has barrier at how many meters in front of blind person.
The voice alerting unit can be with bluetooth connection, which can make blind person not hear to avoid noisy environment
Voice is sent directly in earphone by voice prompting by bluetooth, so that blind person is understood and is heard.
It is equipped with luminance meter and warning light source in the sensor box, the luminance meter and warning light source are and processor
Connection., can be in the brightness of detection ambient enviroment by luminance meter, in the case where surrounding environment light reduces, luminance meter will be believed
Number being sent to processor and being issued an order again by processor makes warning light source issue feux rouges to warn Pedestrians and vehicles around.
The processor is single-chip microcontroller.
The body of rod is the rugosity body of rod, convenient for collecting when not, and it is folding on the market that the rugosity body of rod, which uses,
Folded design.
Protective cover is equipped with above the periphery of the idler wheel, the lower section of the protective cover front end is equipped with telescopic card, institute
The bottom end for stating card is equipped with sheet rubber.When blind person needs to halt, the button on handrail is pressed, card is popped up, the card
Piece is contacted with bottom surface stands blind-guiding stick on the ground, and the sheet rubber of card bottom can play antiskid effect.
Compared with prior art, the beneficial effects of the utility model are embodied in following several respects:
(1) sensor box is set, blind person's prompt can be given in advance, avoids not distinguishing the hair of accident caused by obstacle because of blind person
It is raw；
(2) setting of blind-guiding stick bottom roller so that blind-guiding stick adapts to various terrain environments, and is arranged in idler wheel periphery and blocks
Piece, so that the blind-guiding stick is relatively stable when stopping；
(3) luminance meter and warning light source are set, pedestrian and Warning for vehicle are given in compared with dark situation, reduces what blind person was collided
It may.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model；
Fig. 2 is the test structural schematic diagram of the utility model；
Fig. 3 is the connection schematic diagram of each component in the utility model sensor box.
Wherein, 1 is handle, and 2 be the body of rod, and 3 is at folding, 4 are idler wheel, and 5 be sensor box, and 6 be window, and 7 be protective cover,
8 be card.
Specific embodiment
It elaborates below to the embodiments of the present invention, the present embodiment before being with technical solutions of the utility model
