In 2016, the number of visually impaired people has rapidly increased to 17.31 million. In 2016, the proportion of visually impaired people in my country accounted for 1.26% of the total population, that is to say, there is one visually impaired person for every eighty people, and the existing blind people are generally guided by guide poles.

[0003] With regard to the existing related technologies, the inventors believe that the following defects exist: blind people generally use guide poles to detect whether the ground is continuous. Since they cannot fully detect the position of their feet, their perception function is not comprehensive and they are prone to injury. At the same time, holding the pole by hand for long-term operation consumes a lot of physical strength and walks slowly, which makes it difficult for blind people to travel. Utility Model Content

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0021] Example 1: Please refer to Figure 1 - Figure 3 , an automatically rechargeable split guide vehicle of the present embodiment comprises a guide vehicle body 1 and a magnetic charger 2, a plug slot 4 is provided at one end of the top of the guide vehicle body 1, a magnetic plug 5 is plugged in the plug slot 4, a guide rod 3 is fixedly connected to the top of the magnetic plug 5, the guide rod 3 is located at one end of the top of the guide vehicle body 1, a laser radar scanner 7 is fixedly connected to one end of the guide vehicle body 1, a warning light 8 is fixedly connected to the top of the guide vehicle body 1, and the laser radar scanner 7 comprises a triangulated laser radar and a TOF laser radar;

[0022] Among them, the laser emits laser, and after irradiating the object, the reflected light is received by the linear CCD. Since the laser and the detector are separated by a distance, objects at different distances will be imaged at different positions on the CCD according to the optical path. By calculating according to the trigonometric formula, the distance of the measured object can be deduced;

[0023] Secondly, the laser emits a laser pulse, and the time of emission is recorded by the timer. The returning light is received by the receiver, and the timer records the time of return. The two times are subtracted to get the "flight time" of the light. The speed of light is constant, so it is easy to calculate the distance after knowing the speed and time.

[0024] Furthermore, a fixed arm 6 is fixedly connected to the top of the guide vehicle body 1, a loudspeaker 9 is fixedly connected to one side of the top of the fixed arm 6, a switch 10 is arranged on the other side of the top of the fixed arm 6, a universal wheel 14 is arranged at the bottom of one end of the guide vehicle body 1, and two power wheels 11 are assembled and connected to both sides of the other end of the guide vehicle body 1;

[0025] The distance to the object is calculated by the laser radar scanner 7, and the distance measurement signal is received by the processor built into the guide vehicle body 1. Then, after processing, a sound alarm is issued through the loudspeaker 9, a warning light is issued through the warning light 8, and the motor built into the handle controller 15 vibrates to remind the blind person;

[0026] Secondly, the guide car body 1 can provide ultra-long-distance, 360° blind-angle-free, high-stability, and refined 2.5D navigation. It can provide high-precision navigation with a maximum range of 60 meters, 360° blind-angle-free full coverage, and a response speed of 0.1 seconds, which can escort the blind on their way out. It can provide multi-faceted services through high-op-amp external speakers, wireless headphones, light alarms, motor vibrations, and alarm touch controls.

[0027] Furthermore, the bottom of the magnetic plug 5 is a prism, and the interior of the plug-in slot 4 fits the magnetic plug 5. When the magnetic plug 5 is plugged into the interior of the plug-in slot 4, the surface of the magnetic plug 5 and the interior of the plug-in slot 4 are magnetically connected together, so that the guide pole 3 is connected to the guide vehicle body 1, which is convenient for the blind to hold the handle controller 15 on the top of the guide pole 3, and then guide the blind by moving the guide vehicle body 1;

[0028] Secondly, the magnetic plug 5 is pulled out of the plug slot 4 to separate the guide rod 3 from the guide vehicle body 1. The blind person can hold the handle controller 15 to use the guide rod 3 alone for guiding the blind. The two guiding modes can be switched at will, which is convenient to operate.

[0029] Furthermore, a magnetic suction interface 13 is provided on the top of the magnetic suction charger 2, and the magnetic suction interface 13 is magnetically connected to the charging position at the bottom of the guide vehicle body 1. The guide vehicle body 1 can automatically find the charging position, so that the charging port at the bottom of the guide vehicle body 1 is magnetically connected to the magnetic suction interface 13, and then charging is performed, which can reduce operations;

[0030] Furthermore, a handle controller 15 is fixedly connected to the top of the guide pole 3. The handle controller 15 is made of a flexible material and can be deformed. It can also provide feedback on temperature and vibration, so that the blind can receive information through their palms.

[0031] Furthermore, a protective cover 12 is provided on the top of the power wheel 11, and the inner side of the protective cover 12 is fixedly connected to the two sides of the guide vehicle body 1. By providing the protective cover 12, water can be prevented from splashing onto the guide vehicle body 1 when the power wheel 11 rotates.

[0032] Working principle: The distance to the object is calculated by the laser radar scanner 7, and the distance measurement signal is received by the processor built into the guide vehicle body 1. Then, after processing, a sound alarm is issued through the loudspeaker 9, a warning light is emitted by the warning light 8, and the motor in the handle controller 15 vibrates to remind the blind. By plugging the magnetic plug 5 into the inside of the plug-in slot 4, the guide rod 3 can be connected with the guide vehicle body 1, which is convenient for the blind to guide the blind by moving the guide vehicle body 1. The magnetic plug 5 is pulled out of the plug-in slot 4 to separate the guide rod 3 from the guide vehicle body 1, which is convenient for the blind to use the guide rod 3 alone for guiding the blind. The two guiding modes can be switched at will, and the operation is convenient.

[0033] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
