With the adoption of the voice prompt way exploring walking stick used for the blind person, information from the ground surface of a sidewalk for the blind is directly collected; when the blind person walks out of the sidewalk for the blind in walking, a voice prompt is immediately sent out to remind the blind person to walk on the sidewalk for the blind timely, so that safe walking is ensured.
Description
Technical field
This utility model relates to the crutch that a kind of blind person uses, and especially relates to the voice suggestion pathfinding crutch that a kind of blind person uses.
Background technology
The crutch for blind that circulates in the market, mostly there is no sound prompt function, need the blind person to stop to stand to carry out beating point with the crutch road pavement and visit, can determining and walk on, what some had a sound prompt function also mainly relies on satellite navigation system support.Its weak point is: the satellite navigation system performance is stable not, in case break down, just crutch can't use immediately, if satellite navigation system is made mistakes, also can bring potential safety hazard for blind person's walking.And this satellite navigation system can only inform the barrier situation of blind person's user surrounding of living in, and can not feed back the road surface situation, thereby the user walking of still can not relievedly exploring the way voluntarily.
The utility model content
The technical problem that this utility model mainly solves is to provide the voice suggestion pathfinding crutch that a kind of blind person uses, this utility model directly gathers the information from ground, sidewalk for visually impaired people, when occurring in walking as the blind person partially going, sends immediately voice suggestion, remind its timely correction, to guarantee safe walking.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the voice suggestion pathfinding crutch that provides a kind of blind person to use, comprise: mobile jib, front wheel, rear roller and axle sleeve, described front wheel is positioned at the bottom of described mobile jib and is connected with described mobile jib, described axle sleeve is enclosed within the lower end of described mobile jib, described rear roller is positioned at the rear of described front wheel and is fixedly connected with described axle sleeve, be provided with a pointer and a buzzer on described mobile jib, be provided with a graduated disc on described axle sleeve outer peripheral face, described graduated disc and pointer are electrically connected with power supply respectively.
In preferred embodiment of this utility model, described axle sleeve freely rotates in the lower end of described mobile jib.
In preferred embodiment of this utility model, described graduated disc is provided with three of left, center, right metal contact block.
In preferred embodiment of this utility model, three of described left, center, right metal contact block is connected with an end of power supply respectively, and described pointer is connected with the other end of power supply, and three of described left, center, right metal contact block and described pointer consist of three kinds of circuit loops.
In preferred embodiment of this utility model, described buzzer is connected with circuit loop on described graduated disc.
This utility model makes the blind person in time adjust direction of travel directly according to information of voice prompt, or determines whether walk on, serviceability is reliable and stable, can can't not use because satellite navigation system breaks down, and this utility model cost of manufacture is low, easy to use, be easy to promote.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A of graduated disc of the present utility model and pointer part is to enlarged diagram;
In figure, the labelling of each parts is as follows: 1, mobile jib, 2, buzzer, 3, pointer, 4, graduated disc, 5, rear roller, 6, axle sleeve, 7, front wheel, 8, the metal contact block.
The specific embodiment
The utility model is elaborated below in conjunction with accompanying drawing and concrete preferred embodiment, so that advantage of the present utility model and feature can be easier to be understood by those skilled in the art, these embodiment are only illustrative purposes, are not intended to scope of the present utility model is limited.
see also Fig. 1 and Fig. 2, the voice suggestion pathfinding crutch that this utility model blind person uses comprises: mobile jib 1, front wheel 7, rear roller 5 and axle sleeve 6, described front wheel 7 is positioned at the bottom of described mobile jib 1 and is connected with described mobile jib 1, described axle sleeve 6 is enclosed within the lower end of described mobile jib 1, described rear roller 5 is positioned at the rear of described front wheel 7 and is fixedly connected with described axle sleeve 6, be provided with a pointer 3 and a buzzer 2 on described mobile jib 1, be provided with a graduated disc 4 on described axle sleeve 6 outer peripheral faces, described graduated disc is provided with a left side, in, right three metal contact blocks 8, metal contact block 8 on described graduated disc 4 and pointer 3 are electrically connected with power supply respectively.
In addition, described axle sleeve 6 freely rotates in the lower end of described mobile jib 1.
In addition, three of described left, center, right metal contact block 8 is connected with an end of power supply respectively, and described pointer 3 is connected with the other end of power supply, and three of described left, center, right metal contact block 8 consists of three kinds of circuit loops with described pointer 3.
In addition, described buzzer 2 is connected with circuit loop on described graduated disc 4.
Further, the hand-held crutch walking of the present utility model of blind person, can freely rotate between axle sleeve 6 and mobile jib 1, when the blind person correctly walks along the sidewalk for visually impaired people, front wheel 7 and rear roller 5 on same straight line, and with mobile jib 1 in same plane, this moment, the pointer 3 on mobile jib 1 was connected with intermetallic metal contact block 8 on axle sleeve outer peripheral face graduated disc 4, consist of a loop, make buzzer 2 send the suggestion voice of " asking relieved craspedodrome ", the blind person can continue relieved moving ahead.This prompt tone can be set as every 2-3 minutes and remind once.When blind person's walking departs from sidewalk for visually impaired people (take back or take over), rear roller 5 can not remain on same straight line with front wheel 7, thereby drive axle sleeve 6 around mobile jib 1 rotation, make pointer 3 break away from axle sleeve 6 outer peripheral face graduated discs on being connected of intermetallic metal contact block, and be connected with left metal contact block or right metal contact block, form another circuit loop, this moment, buzzer 2 can send the suggestion voice of " please adjusting direction left " or " please adjusting direction to the right ", and the blind person can point out timely adjustment direction of travel according to this.
