[0002] Smart guide sticks are smart devices that integrate high technology and practical functions. They use advanced technology to provide safer and more convenient navigation and travel experiences for the visually impaired. Most of the internal devices of smart guide sticks require power supply to realize their functions. If the power is exhausted without timely detection, these devices may not work properly, causing the blind to lose important navigation and warning functions during walking, increasing their risk of injury or getting lost.

[0003] For example, a Chinese utility model patent (CN214968673U) discloses an intelligent interactive guide stick, which includes a stick body and a stick handle connected to the top of the stick body. A voice navigation device and a rechargeable battery are arranged in the stick handle. A charging slot is arranged on the stick handle. A magnetic charging head is arranged at the bottom of the charging slot. The magnetic charging head is electrically connected to the rechargeable battery and is used to charge a Bluetooth headset. The utility model is very simple and convenient to use. The blind only needs to insert the Bluetooth headset into the charging slot of the guide stick to start charging. There is no need to carry an additional charging cable and the operation steps of using the charging cable to plug the Bluetooth headset charging interface are reduced. At the same time, the built-in large-capacity rechargeable battery of the guide stick can charge the Bluetooth headset at any time, solving the worry of insufficient battery life of the Bluetooth headset.

The voice broadcast module 15 is a DFP l ayer voice module. Ayer is a commonly used MP3 module, which is often used in devices that require voice prompts, such as guide sticks. The voice broadcast module 15 is located on the top of the information processor 13. A vibration feedback module 16 is provided on one side of the voice broadcast module 15. The vibration feedback module 16 is electrically connected to the controller 10. The voice broadcast module 15 is used to receive signals from the information processor 13 and send converted electrical signals to the sound speaker 4. A vibration feedback module 16 is provided on one side of the voice broadcast module 15. The vibration feedback module 16 is an ERM vibration motor. The vibration feedback module 16 is electrically connected to the controller 10. When the surrounding environment is noisy, the vibration feedback module 16 can remind the user to pay attention to the situation ahead through vibration, so that the user can make corresponding responses.

[0037] The adjusting mechanism includes a rotating roller 17, a rotating knob 18, a first bevel gear 19, a second bevel gear 20, a rotating threaded rod 21 and a crutch head 22. The inner side of the top of the fixed stick 1 is rotatably connected with the rotating roller 17, one end of the rotating roller 17 is fixed with the rotating knob 18, the other end of the rotating roller 17 is fixed with the first bevel gear 19, the first bevel gear 19 is located inside the fixed stick 1, the top of the first bevel gear 19 is meshedly connected with the second bevel gear 20, the inner side of the second bevel gear 20 is fixed with a rotating threaded rod 21, the rotating threaded rod 21 is rotatably connected with the fixed stick 1, and the rotating screw The threaded rod 21 is threadedly connected to the extension stick 2, and a crutch head 22 is fixed to the bottom of the extension stick 2; the length of the guide stick can be better adjusted through the design of the adjustment mechanism, and more precise adjustment can be achieved through the threaded connection between the fixed stick 1 and the rotating threaded rod 21. Since it is manually adjusted, it does not need to rely on electricity or other external energy sources, and is very convenient to use. The battery 8 is electrically connected to the information processor 13, the GPS positioning module 14, the voice broadcast module 15 and the vibration feedback module 16, and the battery 8 provides power for multiple modules inside the handle 3.

[0038] The use process of the novel blind guide crutch provided by the utility model is as follows:

[0039] When the user needs to adjust the length of the guide stick, the user turns the knob 18. Since the knob 18 is fixedly connected to the rotating roller 17 and the rotating roller 17 is rotationally connected to the fixed stick 1, the rotation of the knob 18 drives the rotating roller 17 to rotate, so that the first bevel gear 19 fixed to the rotating roller 17 also rotates. Since the first bevel gear 19 is meshed and connected with the second bevel gear 20, the rotation of the first bevel gear 19 drives the second bevel gear 20 to rotate, so that the rotating threaded rod 21 fixedly connected to the second bevel gear 20 also rotates, so that the extension stick 2 threadedly connected to the rotating threaded rod 21 moves, and the guide stick can be adjusted to a suitable length.

[0040] The ultrasonic sensor inside the hazard alarm 11 calculates the distance of the obstacle by emitting ultrasonic waves and measuring the time it takes for them to reflect back. When the obstacle approaches the set safety distance, the ultrasonic sensor will send a signal to the controller 10 to trigger the alarm mechanism. After receiving the command signal from the controller 10, the voice broadcast module 15 will immediately convert the preset alarm information or real-time information into voice form. This sound alarm is pre-set. The voice broadcast module 15 sends the converted electrical signal to the sound speaker 4, and the sound speaker 4 receives the voice signal output by the voice broadcast module 15 and converts it into sound to remind the user. At the same time, the controller 10 will also send a command to the vibration feedback module 16 to make the vibration feedback module 16 vibrate, and the user's hand will feel the vibration, so that the user can also feel the reminder when the environment is noisy;

[0041] When the user encounters an emergency, the user presses the call button 9 on the guide stick to send a specific instruction or request. The call button 9 sends the instruction signal to the controller 10. The controller 10 receives the instruction signal and parses the instruction according to a preset program or logic. According to the parsed instruction, the information processor 13 sends a corresponding signal to the voice broadcast module 15. After receiving the signal from the information processor 13, the voice broadcast module 15 sends a converted electrical signal to the sound speaker 4 to attract the attention of surrounding pedestrians so that the surrounding pedestrians can help the user in distress.

[0042] The battery 8 provides power for the system. The power detection module 12 detects the power status of the battery 8 in real time and sends the data to the information processor 13. The information processor 13 processes the data and sends instructions to the voice broadcast module 15 as needed. When the battery 8 is low in power, the voice broadcast module 15 sends a converted electrical signal to the speaker 4, and the speaker 4 will sound an alarm to remind the user to slide the dust cover 6 upward. Since the dust cover 6 is fixedly connected to the spring 7, the movement of the dust cover 6 compresses the spring 7. At this time, the charging port 5 is no longer protected by the dust cover 6, and the user connects the charging port 5 to charge the battery 8 through an external charging cable.
