Please refer to FIG. 1 and FIG. 2 simultaneously. FIG. 2 is a schematic diagram of the first grip portion and the second grip portion of the handle 11 in the health-type smart crutches according to an exemplary embodiment of the present invention. In FIG. 2, the second grip portion 11b is detachably coupled to the first grip portion 11a. Further, when the second grip portion 11b is connected to the first grip portion 11a, the two are electrically connected. For example, the end of the second grip portion 11b that is in contact with the first grip portion 11a and the end of the first grip portion 11a that is in contact with the second grip portion 11b respectively have a conductive pad C. When the second grip portion 11b is connected to the first grip portion 11a, the second grip portion 11b can be electrically connected to the first grip portion 11a through the mutual contact of the conductive pads C.

Further, the power supply unit B is disposed in the second grip portion 11b, and the power supply unit B is in contact with the conductive pad C on the second grip portion 11b. For example, the power supply unit B can be a rechargeable battery. In addition, the conductive pad C on the second grip portion 11b is electrically connected to the heart rate sensor 20, the microcontroller 30, and the wireless transmission module 40 through a wire. When the second grip portion 11b is connected to the first grip portion 11a, the power supply unit B contacts the conductive pad C on the second grip portion 11b, and then passes through the second grip portion 11b and the first grip portion. The conduction of the conductive pads C on the portion 11a can supply power to the heart rate sensor 20, the microcontroller 30, and the wireless transmission module 40.

The healthy smart cane provided in this embodiment further includes a light-emitting element 70. The light-emitting element 70 is disposed on the second grip portion 11b away from one end of the first grip portion 11a and electrically connected to the power supply unit B. That is, the user can detach the second grip portion 11b and use the second grip portion provided with the power supply unit B and the light-emitting element 70 as a light-emitting device (ie, a flashlight).

In addition, a USB port 50 is provided on the health smart cane. Through the USB port 50, the health smart cane can externally connect an external power source to charge the power supply unit B. However, in addition to charging the power supply unit B with an external power source, the health-type smart cane provided in this embodiment can also generate the power required for its operation. In detail, please refer to FIG. 1 and FIG. 3 simultaneously. FIG. 3 is a schematic diagram of a charging device in a healthy smart cane according to an exemplary embodiment of the present invention. As shown in FIG. 1, the charging device 60 is disposed in the shaft 13 of the healthy smart cane. As shown in FIG. 3, the charging device 60 includes a magnetic unit 60a and a coil 60b. During the user's travel with a healthy smart cane, the swing of the user's hand causes the healthy smart cane to be subjected to external forces. Then, the coil 60b in the charging device 60 slides up and down to the magnetic unit 60a. In this way, by electromagnetic induction, a current is generated on the coil 60b (this is regarded as a charging current), and then a wire (not shown) passing through points a and b at both ends of the coil 60b is supplied to the power. Supply unit B to charge.

In short, the health smart cane provided in this embodiment can be connected to an external power source for charging, and can also generate current by the charging device 60 to charge. For users who are performing mountaineering or hiking, it is often difficult to find an external power source that can recharge a healthy smart cane in an outdoor environment. However, with the charging device 60, the healthy smart cane provided in this embodiment can be self-generated. The charging current is ideal for outdoor environments.

As shown in FIG. 1 , the healthy smart cane provided in this embodiment further includes a gyroscope 80 . The gyroscope 80 is disposed in the first grip portion 11a of the handle 11 for measuring the tilt angle of the healthy smart cane (ie, the angle with the normal line of the ground), and transmitting the measured tilt angle To the microcontroller 30. Then, after receiving the tilt angle measured by the gyroscope 80, the microcontroller 30 determines whether the tilt angle is greater than a preset angle, such as: 60 degrees. If the tilt angle is greater than the preset angle, the microcontroller 30 further determines whether the tilt angle is greater than the preset angle for a predetermined period of time, such as: 20 seconds.

For example, if the user accidentally falls during the journey, the healthy wisdom cane may fall to the ground. At this time, the tilt angle measured by the gyroscope 80 may be greater than the preset angle. At the same time, since the user may not be able to get up and walk after accidentally falling, there should be a period of time when the tilt angle measured by the gyroscope 80 is greater than the preset angle. Therefore, when the microcontroller 30 determines that the tilt angle measured by the gyroscope 80 is greater than the preset angle, and determines that the situation continues for a preset time, the microcontroller 30 generates a second alert signal and transmits the wireless signal through the wireless transmission. The module 40 transmits the second warning signal to the external device.

That is to say, when the remote caregiver receives the second warning signal mentioned above through the device held, it means that an unexpected situation may occur during the user's travel, and the remote caregiver can immediately contact the user. To find out if it needs assistance.

As shown in FIG. 1 , the health smart cane provided in this embodiment further includes a voltage sensor 91 connected to the charging device 60 to sense the charging device. The voltage value of the generated charging current is 60 and the sensed voltage value is transmitted to the microcontroller 30. In detail, the charging device 60 generates a charging current by sliding the coil 60b therein up and down to the magnetic unit 60a, wherein the charging current has a periodicity in the process of sliding the coil 60b up and down in the magnetic unit 60a. Variety. Thus, in the present embodiment, the voltage sensor 91 senses the voltage value of the charging current generated by the charging device 60 and transmits the voltage value to the microcontroller 30. When the voltage value is lower than the preset threshold voltage to reach the preset threshold voltage, the microcontroller 30 counts once to count as the number of steps performed by the user. In addition, the microcontroller 30 can also calculate the calories burned by the user based on the number of steps counted. The number of steps counted by the microcontroller 30 and the corresponding calculated calories can be transmitted to an external device (eg, a user's handheld electronic device) through the wireless transmission module as a record, and the user is informed of the activity process. The number of steps accumulated in the calories burned.

Finally, the healthy smart cane provided in this embodiment further includes a suspended particle sensor 90. As shown in FIG. 1, the aerosol sensor 90 is disposed on the shaft 13 of the healthy wisdom cane, and is mainly used to detect the concentration of suspended particles flowing through the composition of one of the aerosol sensors 90. For example, the aerosol sensor can be a PM2.5 sensor, that is, the suspended particles it senses are fine aerosols (particle size less than 2.5 μm). Please refer to FIG. 4. FIG. 4 is a schematic diagram of a sensor in a healthy smart cane according to an exemplary embodiment of the present invention. As shown in Figure 4, the aerosol sensor 90 has a hollow structure for sensing the concentration of aerosols in the composition of the hollow structure. After sensing the concentration of the suspended particles flowing through the composition of the hollow structure, the measured concentration of the suspended particles is transmitted to the microcontroller 30. Next, the microcontroller 30 determines whether the concentration of the suspended particles is greater than a preset concentration value. If the microcontroller 30 determines that the concentration of the suspended particles measured by the sensor is greater than the preset concentration value, a third warning signal is generated, and the third warning signal is transmitted to the external device through the wireless transmission module 40.

That is to say, when the user receives the third warning signal mentioned above through the holding device, the concentration of suspended particles in the current environment, such as fine aerosols, can be known. In this way, the user can consider whether to suspend their hiking or hiking trips to avoid inhaling too much harmful substances and damaging health.

Finally, in the embodiment, the wireless transmission module 40 used by the health smart cane can be a Bluetooth transmission module, a Wi-Fi transmission module, a 3G communication module, a 4G communication module or Combination to balance data transmission between close and long distances. In addition, the microcontroller 30 used by the Healthy Smart Cane can be a single-chip microcontroller written in the Arduino language. However, the present invention is not limited to the implementation of the wireless transmission module 40 and the microcontroller 30 used by the healthy smart cane.
