Abstract

The invention discloses a voice-prompt way-exploring walking stick for the blind person. The voice-prompt way-exploring walking stick comprises a main rod, a front idler wheel, a rear idler wheel and a shaft sleeve, wherein the front idler wheel is arranged at the bottom end of the main rod and is connected with the main rod, the shaft sleeve is sleeved at the lower end of the main rod, the rear idler wheel is arranged behind the front idler wheel and is fixedly connected with the shaft sleeve, the main rod is provided with a pointer and a buzzer, a dial is arranged on the peripheral surface of the shaft sleeve, the dial and the pointer are respectively and electrically connected with a power supply, the shaft sleeve can move freely at the lower end of the main rod, the dial is provided with left, middle and right metal contact blocks which are respectively connected with one end of the power supply, the pointer is connected with the other end of the power supply, each of the left, middle and right metal contact blocks forms a circuit loop together with the pointer, and thus totally three circuit loops are formed. The voice-prompt way-exploring walking stick directly collects information from the ground of a road for the blind person, and when the blind person moves to one side when walking, the walking stick immediately gives out voice prompt to remind the blind person of correcting timely, thus ensuring that the blind person can walk safely.

Description

The voice suggestion pathfinding crutch that a kind of blind person uses
Technical field
The present invention relates to the crutch that a kind of blind person uses, especially relate 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 not 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.
Summary of the invention
The technical problem that the present invention mainly solves provides the voice suggestion pathfinding crutch that a kind of blind person uses, the present invention directly gathers the information from ground, sidewalk for visually impaired people, when partially going appears in walking in the blind person, sends immediately voice suggestion, remind its timely correction, to guarantee safe walking.
For solving the problems of the technologies described above, the technical solution used in the present invention 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 the described mobile jib, be provided with a graduated disc on the described axle sleeve outer peripheral face, described graduated disc and pointer are electrically connected with power supply respectively.
In a preferred embodiment of the present invention, described axle sleeve freely rotates in the lower end of described mobile jib.
In a preferred embodiment of the present invention, described graduated disc is provided with three the metal contact blocks in left, center, right.
In a preferred embodiment of the present invention, three the metal contact blocks in described left, center, right are connected with an end of power supply respectively, and described pointer is connected with the other end of power supply, and three the metal contact blocks in described left, center, right and described pointer consist of three kinds of circuit loops.
In a preferred embodiment of the present invention, described buzzer is connected with circuit loop on the described graduated disc.
The present invention 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 cost of manufacture of the present invention is low, easy to use, be easy to promote.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is that the A of graduated disc of the present invention and pointer part is to enlarged diagram;
The labelling of each parts is as follows among the figure: 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 present invention will be described in detail below in conjunction with accompanying drawing and concrete preferred embodiment, so that advantages and features of the invention can be easier to be understood by those skilled in the art, these embodiment only are illustrative purposes, are not intended to scope of the present invention is limited.
See also Fig. 1 and Fig. 2, the voice suggestion pathfinding crutch that blind person of the present invention 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 the 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, the metal contact block 8 on the 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 the metal contact blocks 8 in described left, center, right are connected with an end of power supply respectively, and described pointer 3 is connected with the other end of power supply, and three metal contact blocks in described left, center, right 8 consist of three kinds of circuit loops with described pointer 3.
In addition, described buzzer 2 is connected with circuit loop on the described graduated disc 4.
Further, blind person's crutch walking hand-held of the present invention, can freely rotate between axle sleeve 6 and the 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 the mobile jib 1 linked to each other with intermetallic metal contact block 8 on the 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 per 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 the 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 the linking to each other of intermetallic metal contact block, and link to each other 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.
