[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Example: Reference Figure 1-10 The multifunctional smart guide cane shown includes a handle and a cane shaft. The handle is connected to the cane shaft via a connector 6, and the connector 6 has a hole in which an ultrasonic ranging module is installed. The handle also has a battery compartment for housing a battery 12, and next to the battery compartment is a chamber for housing a control module 11. The control module 11 includes a Bluetooth anti-loss module, a light sensor 5, and a fall detection alarm module, and is also connected to the ultrasonic ranging module. A microcontroller controls the various modules on the guide cane. The battery 12 powers all the electrical components on the smart guide cane. A button on the back of the handle activates the fall detection alarm module. Activating the button causes the GSM module in the fall detection alarm module to send a message to inform family and friends of the fall, and with the help of the positioning module, family and friends are informed of the fall location.

[0041] The front of the handle has an earphone case 14 that can hold Bluetooth headphones, and the earphone case 14 is connected to the battery 12, thereby achieving the purpose of powering the earphone case 14 and the Bluetooth headphones.

[0042] A start / stop control module 11 switch 4 is provided on the side wall of the handle. Through the Bluetooth anti-loss module in the control module 11, the microcontroller sends a command to the Bluetooth anti-loss module and waits for the Bluetooth device to connect to it.

[0043] The camera 13 mounted on the handle, together with the Bluetooth anti-loss module and Bluetooth headset, alerts the blind person to objects appearing in front of them while walking, thanks to the signal transmission from the microcontroller.

[0044] The anti-slip strip 1 on the handle increases the friction between the handle and the hand, reducing the possibility of slipping out of the hand.

[0045] When using a guide cane, the fall detection alarm module can also work with a tilt sensor to detect the position of the guide cane. If it is upright, it can be used normally. When the tilt angle of the guide cane (to the ground) is less than 60 degrees or parallel to the bottom surface, it will work with a buzzer and LED light 3 to flash the light and sound an alarm (it will only be activated after 20 seconds in this state).

[0046] The ultrasonic ranging module, controlled by a microcontroller, detects objects in front of it during operation. If the distance is less than X distance, it will sound an alarm in conjunction with a buzzer and Bluetooth headset, thus achieving distance measurement and obstacle avoidance warning.

[0047] The tip 10, which is threaded at the bottom of the cane, can be quickly replaced.

[0048] In order to make it easier for people around to see the blind person when he / she is out, a light source is installed on the cane. The light source is connected to the battery 12 and the control module 11 through wires, so that in conjunction with the light sensor 5 and the buzzer, the light source will increase the brightness or flash to different degrees when the above situation occurs.

[0049] The first walking stick 7 has a first groove at its bottom and a threaded section at the bottom of the first groove. The second walking stick 8 is slidably connected in the first groove, and the top of the second walking stick 8 is slidably connected to the first walking stick 7. Below the threaded section (the first groove has a first mounting groove 71), a conductive first sliding contact piece 75 is installed in the first mounting groove 71. The first mounting groove 71 has a first through hole 72 that communicates with the outside. The inner wall of the first through hole 72 has a first wiring hole 73 that communicates with the top. Through the structural design of the first through hole 72, after the wire passes through the first wiring hole 73, it is convenient for the wire end to be connected to the first sliding contact piece 75. The inner wall of the first wiring hole 73 has a first light source hole 74 that communicates with the outside. The light source in the first light source hole 74 is connected to the wire, so that the light source can be used normally under the power supply of the battery 12.

[0050] The bottom of the second rod 8 is provided with a second sliding groove, and a third rod 9 is slidably connected in the second sliding groove. The top of the third rod 9 is threadedly connected to the bottom of the second rod 8. A second mounting groove 81 is provided on the outer wall of the second rod 8, and a groove 85 is provided on the bottom outer wall of the second rod 8. The groove 85 and the second mounting groove 81 are connected through a second wiring hole 83. A second light source hole 84 is provided on the inner wall of the second wiring hole 83, which is connected to the outside. A light source is also provided in the second light source hole 84, and the light source is connected to the second sliding contact piece 82 through an electric wire. Through the structural design of the second rod 8, when the second rod 8 and the first rod 7 are threadedly connected, the second sliding contact piece 82 and the first sliding contact piece 75 are in contact, thereby achieving the purpose of series connection.

[0051] In order to protect the groove 85 and the first perforation 72, a second sealing block 86 and a first sealing block 76 are respectively inserted into the groove 85 and the first perforation 72.

[0052] The bottom of the third staff 9 is threaded with a staff tip 10, which facilitates the replacement of the staff tip 10.

[0053] Volume button 2 on the outer wall of the handle controls the volume of the buzzer.

[0054] The working principle of this utility model is as follows: By opening the earphone compartment 14, the Bluetooth earphone is taken out and worn on the blind person's ear. Then, the cane is pulled out, and the second cane 8 and the third cane 9 are rotated in sequence to complete the unfolding preparation of the cane. During this process, the first sliding contact piece 75 on the first cane 7 and the second sliding contact piece 82 on the second cane 8 come into contact, realizing the series connection between the two sets of wires. Then, under the power supply of the battery 12, the light sources in the first light source hole 74 and the second light source hole 84 are in a standby state. When the ambient light intensity drops to a threshold (the threshold is less than 500, and the LED light 3 lights up 3 times), under the action of the light sensor 5, in conjunction with the microcontroller in the control module 11, instructions are transmitted to increase the brightness of the light source so that people around can know the location of the blind person.

[0055] The ultrasonic ranging module on connector 6 can detect obstacles in front of a blind person while they are walking, and can remind the blind person in conjunction with a buzzer and Bluetooth headset; at the same time, camera 13 can provide auxiliary prompts in conjunction with the above components during the day.

[0056] Furthermore, the volume button 2 on the front of the handle can adjust the volume of the buzzer according to the noise level of the surrounding environment; the switch 4 on the side wall of the handle controls the start and stop of the module 11; and the anti-slip strip 1 on the handle increases the friction between the handle and the hand.

[0057] By controlling the fall detection alarm module in module 11, an alarm will be triggered if the guide cane is lying flat for more than 20 seconds. The GSM module can also be activated by the button on the back of the handle to send a text message, and then the mobile phone will send messages to relatives and friends.

[0058] When the Bluetooth headset and the Bluetooth module on the guide cane are more than 5 meters apart, the microcontroller detects the change and controls PC15 to sound a buzzer and illuminate the indicator light connected to the buzzer. This audio-visual alert helps the user find the item. When the user finds and approaches the lost Bluetooth headset, the lost Bluetooth module will reconnect to another Bluetooth module on the guide cane. Once the microcontroller detects the restored connection, it stops the buzzer and turns off LED indicator 3. When the user is not using this function, the microcontroller puts the Bluetooth module into sleep mode to reduce power consumption and extend overall battery life.

[0059] The electromechanical connections involved in this utility model are common practices used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments; they are common knowledge.

[0060] Components not described in detail in this article are existing technologies.

[0061] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
