[0046] The load unit 102 is a component in the wearable body 10 that works in a power supply state, and the energy storage unit 106 is a component in the wearable body 10 that stores electrical energy, such as a battery. The power generation unit can generate electrical energy under certain conditions to power the energy storage unit 106 or the load unit 102, and each power generation module in the power generation unit is powered separately without affecting each other.

[0047] The solar power generation layer 302 converts light energy into electrical energy. The light energy here is ambient light, including indoor light sources, sunlight, etc. The solar power generation module 202 includes a plurality of solar power generation layers 302. When there are multiple solar power generation layers 302, the multiple solar power generation layers 302 are connected in parallel and / or in series. Figure 2 An example is given in which a plurality of solar power generation layers 302 are connected in series.

[0048] There is a coil in the near-field communication power generation layer 304. In the process of payment, information exchange (data transmission) and other application scenarios, power is generated during the communication process to provide electric energy.

[0050] Randomly select two watch straps 20 in the wearable electronic device, and there is a different number of power generation layers in at least one power generation module between the two watch straps 20, for example, the number of solar power generation layers 302 in the solar power generation module 202 between the two watch straps 20 is different.

[0051] The control unit 104 confirms a target strap 201 among multiple straps 20 according to environmental information, where the environmental information includes illumination information, application scenario information, and temperature information. The illumination information represents the illumination intensity of the ambient illumination of the wearable electronic device.

The application scenario information represents the usage frequency of application scenarios such as payment and information exchange during the use of the wearable electronic device. When the usage frequency is greater than a frequency threshold, the control unit 104 selects the strap 20 with a large number of near-field communication power generation layers 304 as the target strap 201. The temperature information represents the temperature difference between the ambient temperature and the human body temperature during the use of the wearable electronic device. When the temperature difference is greater than a temperature threshold, the control unit 104 selects the strap 20 with a large number of thermoelectric power generation layers 306 as the target strap 201. The method of confirming the target strap 201 among multiple straps 20 according to the environmental information optimizes the energy collection and power generation efficiency of the power generation unit of the target strap 201, thereby improving the endurance of the wearable electronic device.

[0052] The control unit 104 is respectively connected to the energy storage unit 106, the load unit 102 and the power generation unit in the target strap 201, and controls the power generation unit in the target strap 201 and / or the energy storage unit 106 to supply power to the load unit 102, so that the load unit 102 works normally.

[0053] In the above-mentioned wearable electronic device, the control unit 104 confirms the target strap 201 among the multiple straps 20 according to the environmental information, so that the energy collection and power generation efficiency of the power generation unit of the target strap 201 are optimized; the control unit 104 is connected to the energy storage unit 106, the load unit 102 and the power generation unit in the target strap 201, controls the power generation unit in the target strap 201 and / or the energy storage unit 106 to supply power to the load unit 102, thereby improving the endurance of the wearable electronic device.

[0054] join Figure 2 In one embodiment, the control unit 104 is used to control the energy storage unit 106 to supply power to the load unit 102 when the energy storage voltage of the energy storage unit 106 is greater than the working voltage of the load unit 102, so as to provide a stable output voltage to the load unit 102 so that the load unit 102 can operate stably; wherein the energy storage voltage represents the amount of electricity stored in the energy storage unit, and the working voltage represents the amount of electricity required for the load unit 102 to work normally.

[0056] In one embodiment, the control unit 104 is further used to control the power generation unit in the target strap 201 to supply power to the load unit 102 when the energy storage voltage is lower than the working voltage. When the energy storage voltage is lower than the working voltage, the energy storage unit 106 cannot supply power to the load unit 102, and the power generation unit in the target strap 201 supplies power to the load unit 102, so that the load unit 102 works normally, and the influence of the energy storage unit 106 on the power generation unit of the target strap 201 supplying power to the load unit 102 is eliminated, thereby improving the endurance of the wearable electronic device.

[0057] In one embodiment, the control unit 104 is further configured to control the power generation unit in the target strap 201 to supply power to the energy storage unit 106 when the power generation voltage of the power generation unit in the target strap 201 is greater than the target voltage and the energy storage voltage is less than the working voltage; wherein the target voltage is greater than the working voltage. This setting enables the power generation unit in the target strap 201 to maintain the normal operation of the load unit 102 while storing excess power in the energy storage unit 106, thereby increasing the endurance of the wearable electronic device.
