[0023] 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.
[0024] A smart wearable device, such as Figure 1 and Figure 2 As shown, the device includes a smart wearable device housing 1, a charging interface module 2 supporting water immersion sensing, a built-in battery 8, and an alarm device 9. The built-in battery 8, alarm device 9, and charging interface module 2 supporting water immersion sensing are built into the smart wearable device housing 1. The charging interface module 2 supporting water immersion sensing includes a common electrode assembly 3, a charging circuit 4, a water immersion detection circuit 6, and a smart control circuit 7. The common electrode assembly 3 is disposed in the interface slot of the smart wearable device housing 1. The common electrode assembly 3 is connected to the smart control circuit 7, the charging circuit 4, and the water immersion detection circuit 6. The common electrode assembly 3 is connected to the built-in battery 8 through the charging circuit 4 to charge the built-in battery. The common electrode assembly 3 is connected to the water immersion detection circuit 6. The water immersion detection circuit 6, the charging circuit 4, and the alarm device 9 are connected to the smart control circuit 7.
[0025] Please refer to Figure 3 The invention also provides a corresponding smart wearable device charging cable 10, the end of which has an external charging interface.
[0026] When the external charging interface is connected to the shared electrode assembly, the intelligent control circuit detects the electrode voltage difference, switches to charging mode, activates the charging circuit, and disconnects or puts the water immersion detection circuit in a high-resistance state. The water immersion detection circuit is not operational, and the shared electrode assembly, acting as the electrode of the external charging interface, charges the built-in battery. The intelligent control circuit continuously monitors the electrode voltage difference, which can be data such as the resistance, current, voltage, and remaining battery capacity of the charging interface. When the external charging interface is disconnected from the shared electrode assembly, the circuit switches to water immersion detection mode, activates the water immersion detection circuit, and disconnects or puts the charging circuit in a high-resistance state. The water immersion detection circuit monitors the resistance or capacitance changes between the electrodes of the shared electrode assembly in real time, acquiring water immersion identification information. When the water immersion identification information is a water immersion signal, the intelligent control circuit sends an alarm signal through an alarm device.
[0027] Furthermore, when the water immersion identification information is a water immersion signal, the intelligent control circuit shuts off the power supply to most modules and only sends an alarm signal through the alarm device.
[0028] In this embodiment, the smart wearable device is a smart ring worn on the hand of a maritime worker or a surface rescue worker. When the smart wearable device is submerged in water, it indicates that the user has fallen into the water. The smart wearable device continuously emits an alarm signal, which is received by a nearby underwater acoustic beacon, which then emits a light alarm signal or a light-sound alarm signal. The alarm signal enables underwater positioning and search and rescue, ensuring that the location of the person in the water can be determined and rescued in the shortest possible time.
[0029] Even if the drowning person cannot be rescued in time, by shutting off the power supply to most modules of the intelligent control circuit, all the power is used only to send alarm signals through the alarm device, ensuring that the intelligent wearable device can send alarm signals for a long time, so that the subsequent rescuers can eventually find the location of the drowning person's body.
[0030] In other embodiments, the smart wearable device may also be one of the following: a smart bracelet, a smart ankle bracelet, a smart watch, or other smart wearable devices that are not easily detached.
[0031] In this embodiment, the common electrode assembly is made of titanium alloy, which has excellent conductivity and corrosion resistance and can be used in seawater or other saline-alkali environments.
[0032] In other embodiments, the common electrode assembly may be made of gold-plated or other alloy materials.
[0033] In this embodiment, the common electrode assembly includes a positive electrode and a negative electrode, which are arranged side by side in the interface slot of the smart wearable device housing. In other embodiments, they may be placed on both sides of the interface slot of the smart wearable device housing.
[0034] In this embodiment, the outer shell of the smart wearable device has a waterproof structure with an IPX-8 waterproof rating. In other embodiments, the smart wearable device may also have an IPX-7 waterproof rating.
[0035] Since traditional wireless communication signals have a very short propagation distance underwater, in this embodiment, the alarm device is an underwater beacon communication module, which emits sound waves to provide alarm and underwater location information, making it easier for search and rescue personnel to search for and locate smart wearable devices on the water surface using underwater beacon search and positioning devices.
[0036] In other embodiments, the smart wearable device further includes a wireless communication module connected to the smart control circuit. The wireless communication module is used to communicate with other smart devices (such as mobile phones). When an alarm occurs, the wireless communication module can also send an alarm signal as a supplementary alarm module.
[0037] This utility model also provides a charging interface module that supports water immersion sensing function, including a common electrode assembly, a water immersion detection circuit, a charging circuit, and an intelligent control circuit;
[0038] The shared electrode assembly is connected to the intelligent control circuit, the charging circuit, and the water immersion detection circuit, respectively. The shared electrode assembly charges the corresponding built-in battery through the charging circuit. The shared electrode assembly is connected to the water immersion detection circuit, and the water immersion detection circuit and the charging circuit are connected to the intelligent control circuit. When the external charging interface is connected to the shared electrode assembly, the intelligent control circuit detects a charging signal, switches to charging mode, activates the charging circuit, and disconnects or puts the water immersion detection circuit in a high-resistance state. The shared electrode assembly, as the electrode of the external charging interface, charges the built-in battery, and the intelligent control circuit continuously monitors the charging parameters. When the external charging interface is disconnected from the shared electrode assembly, the system switches to water immersion detection mode, activates the water immersion detection circuit, and disconnects or puts the charging circuit in a high-resistance state. The water immersion detection circuit monitors the resistance or capacitance changes between the electrodes of the shared electrode assembly in real time and obtains water immersion identification information.
[0039] This utility model also provides a method for implementing the aforementioned charging interface that supports immersion sensing function, comprising the following steps:
[0040] When the charging cable plug is connected to the common electrode assembly, the intelligent control circuit detects the charging signal, switches the common electrode assembly to the charging mode, activates the charging circuit, and puts the water immersion detection circuit in a high-resistance state, so that the common electrode assembly can transfer electrical energy to the battery.
[0041] When the charging cable plug is disconnected from the common electrode assembly, the intelligent control circuit switches the common electrode assembly to the immersion detection mode, disconnects the charging circuit, and activates the immersion detection circuit. The immersion detection circuit monitors the resistance or capacitance changes between the common electrode assemblies in real time. When a significant change occurs, the immersion detection circuit transmits an alarm signal to the intelligent control circuit. After receiving the alarm signal, the intelligent control circuit disables unnecessary functions.
