Therefore, there will be a scenario of charging while using. However, this scenario will cause the problem of temperature rise. Since AR glasses are wearable products, the user's temperature rise experience is very important. However, the existing solutions still need to be further improved for the user's temperature rise experience.

Summary of the Invention

[0014] In a possible implementation manner, before the step of turning off the second charging chip, the charging method of the smart wearable device further includes: detecting a charger insertion signal of the smart wearable device; in response to the charger insertion signal, turning off the second charging chip.

[0015] In a possible implementation manner, when the smart wearable device is in a working state, the second charging chip is turned off, and the battery is charged only through the first charging chip.

[0039] Steps S11 to S14 Specific implementation manner

[0040] The following uses specific specific examples to illustrate the implementation manners of the present application. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0041] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present application in a schematic manner. Therefore, only the components related to the present application are shown in the diagrams, rather than being drawn according to the number, shape, and size of the components in actual implementation. The types, quantities, and proportions of the components in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0042] Taking the AR glasses as an example of the smart wearable device, the AR glasses are small in size and have little heat dissipation space. Therefore, in hardware design, in order to avoid heat source aggregation, the heat sources are dispersed as much as possible. However, since the platform-side charging function is integrated in the power management chip, the power management chip must be on the same board as the CPU (Central Processing Unit / Processor). In order to reduce the temperature rise problem in the charging scenario, a third-party charging chip and the platform-side power management chip can be used to participate in the charging work together. The third-party charging chip is placed on the other side of the PCB (Printed Circuit Board). When charging with a large current, the third-party charging chip is used for charging to reduce the temperature rise of the single-sided PCB.

[0043] The charging method, storage medium, device, and wearable device of the smart wearable device described in the present application can reduce the problem of high temperature rise when the smart wearable device is charging and in use while ensuring the normal progress of each charging process.

[0044] The following will elaborate in detail the principles and implementation manners of a charging method, storage medium, device, and wearable device of a smart wearable device in this embodiment with reference to all the drawings, so that those skilled in the art can understand the charging method, storage medium, device, and wearable device of the smart wearable device in this embodiment without creative labor.

[0045] Please refer to Figure 1, which shows the principle flowchart of the charging method of the smart wearable device of the present application in an embodiment. As Figure 1 shown, a charging method for a smart wearable device is applied to the smart wearable device, and the smart wearable device includes a first charging chip, a second charging chip, and a battery.

[0046] Please refer to Figure 2 , which shows the schematic structural diagram of the AR glasses of the charging method of the smart wearable device in an embodiment of the present application. As Figure 2 shown, the first charging chip is a power management chip, and the second charging chip is a third-party charging chip. In this AR glasses structure, the positions of the two lenses are respectively display areas, the upper end of the left temple is the platform end, which includes a CPU and a power management chip, etc., and the lower part is the battery of the left temple; the upper end of the right temple is a third-party charging chip, and the lower part is the battery of the right temple.

[0047] As an example rather than a limitation, the first charging chip and the processor in the above AR glasses can be set at the upper or lower end of the right temple. Correspondingly, the second charging chip can also be set at the upper or lower end of the left temple.

[0048] It should be understood that, correspondingly, the batteries of the left temple and the right temple can also change with the changes in the positions of the first charging chip, the processor, and the second charging chip.

[0049] It should also be noted that, as an example rather than a limitation, in the embodiments of the present application, the first charging chip can be either on the same circuit board of the same temple as the processor, or the first charging chip can be not on the same circuit board of the same temple as the processor, for example, on different circuit boards, or the first charging chip can also be set on the frame body, or can also be set outside the temple (for example, protruding from the temple).

[0050] In some descriptions of the embodiments of the present application, the left temple and the right temple can also be referred to as the first temple, the second temple, or the relatively arranged temples, etc. That is to say, in some descriptions, "left temple, right temple" has the same meaning as "first temple, second temple", "relatively arranged temples" and can be equivalently replaced. The charging method of the smart wearable device specifically includes the following steps:

[0051] S11, obtain the voltage of the battery, and determine the current charging stage of the battery according to the voltage; the charging stage includes a pre-charging stage, a constant current charging stage, and a constant voltage charging stage.

[0052] In practical applications, the charging process of smart wearable products such as AR glasses consists of several stages: trickle charging, pre-charging, constant current charging, and constant voltage charging. Different stages are distinguished by the charging chip detecting the battery voltage. Different battery voltages correspond to different charging stages, and the charging current magnitudes are also different. The constant current stage is the stage with the largest charging current.

[0053] S12. In response to the current charging stage being the pre-charging stage or the constant voltage charging stage, turn on the first charging chip to charge the battery and turn off the second charging chip.

[0054] Please refer to Figure 3 , which shows a schematic diagram of the first charging chip charging in the charging method of the smart wearable device in an embodiment of the present application. As Figure 3 shown, the third-party charging chip is default closed in hardware and enabled to be controlled by software through a control signal. Because the current when the two charging chips work simultaneously is large and has an impact on the battery; and there is no power supply path for the third-party charging chip, abnormal startup will occur when using the third-party IC at low battery levels. The specific implementation process is as follows:

[0055] (1) Insert the charger. The platform end recognizes the insertion of the charger, wakes up the system, and the system executes the charging process.

[0056] (2) The power management chip fixedly sets the battery charging current and keeps the third-party charging chip in a closed state continuously.

[0057] In an embodiment, in response to the voltage reaching the second preset value, it is determined that the current charging stage changes from the constant current charging stage to the constant voltage charging stage, turn on the first charging chip to charge and turn off the second charging chip.

[0058] In an embodiment, the step of, in response to the current charging stage being the constant voltage charging stage, turning on the first charging chip to charge the battery and turning off the second charging chip further includes: setting the floating charge voltage of the first charging chip to the voltage specification of the battery cell and limiting the charging battery current of the current first charging chip not to exceed the preset current until the battery is fully charged.

[0059] Specifically, in order to prevent the situation where the battery cannot be fully charged and there are repeated charge and discharge cycles, the last 5% of the battery power switches back to the platform power management chip for charging until it is fully charged. The specific implementation process is as follows:

[0060] 1) When it is detected that the battery power has reached 95%, the software turns off the third-party charging chip and re-enables the charging function of the platform power management chip.

[0061] 2) Set the floating charge voltage of the power management chip to the voltage specification of the battery cell, and limit the charging current of the battery of the power management chip at this time to be no greater than a certain value until it is fully charged.

[0062] 3) At the same time, behaviors such as floating charge also depend on the charging of the power management chip for setting.

[0063] Among them, the battery power is in the form of a percentage, and the battery voltage value is the actual charging voltage value. Thus, the first preset value and the second preset value can be percentage thresholds set relative to the percentage of the battery power, or voltage thresholds set for the battery voltage value.

[0064] S13. In response to the current charging stage being the constant current charging stage, turn on the second charging chip to charge the battery, and turn off the first charging chip.

[0065] In one embodiment, step S13 specifically includes: in response to the voltage reaching the first preset value, determining that the current charging stage is the constant current charging stage, turning on the second charging chip for charging, and turning off the first charging chip.

[0066] Please refer to Figure 4 , which shows the charging schematic diagram of the second charging chip of the charging method of the smart wearable device in an embodiment of the present application. As Figure 4 shown, when the battery power or the battery voltage value meets a certain condition, switch to charging with a third-party charging chip, turn off the charging path of the platform power management chip, and the software turns on the enable of the third-party charging through a control signal.

[0067] The CPU controls the third-party charging chip to set the battery charging current to a constant current value through a signal, and charges with this charging current until the last 5% of the power.

[0068] In one embodiment, the step of turning on the second charging chip for charging includes:

[0069] The second charging chip receives a first control signal, and the first control signal is used to indicate the enable of the second charging chip.

[0070] In one embodiment, in response to the current charging stage of the battery being the constant current charging stage, set the battery charging current of the second charging chip to a constant current value..

[0071] In one embodiment, before the step of obtaining the voltage of the battery, the charging method of the smart wearable device further includes: turning off the second charging chip.

[0072] In one embodiment, before the step of turning off the second charging chip, the charging method of the smart wearable device further includes:

[0073] (1) Detect the charger insertion signal of the smart wearable device.

[0074] (2) In response to receiving the charger insertion signal, turn off the second charging chip.

[0075] In one embodiment, when the smart wearable device is in a working state, the second charging chip is turned off, and the battery is charged only through the first charging chip.

[0076] The protection scope of the charging method of the smart wearable device described in this application is not limited to the execution order of the steps listed in this embodiment. Any solution achieved by adding or subtracting steps of the prior art or replacing steps according to the principle of this application is included in the protection scope of this application.

[0077] This embodiment provides a computer-readable storage medium. The computer-readable storage medium stores a computer program. The computer program includes program instructions. When the program instructions are executed by a computer, the computer is enabled to execute the charging method of the smart wearable device.

[0078] Those of ordinary skill in the art can understand that all or part of the steps of implementing the above method embodiments can be completed by hardware related to a computer program. The foregoing computer program can be stored in a computer-readable storage medium. When the program is executed, it executes the steps including the above method embodiments; and the foregoing computer-readable storage medium includes: various computer storage media such as ROM, RAM, magnetic disk, or optical disc that can store program codes.

[0079] Please refer to Figure 5 , which shows the schematic structural connection diagram of the electronic device of the present invention in one embodiment. As Figure 5 shown, this embodiment provides an electronic device 1, specifically including a processor 11 and a memory 12. Instructions are stored in the memory 12. When the processor 11 executes the instructions, the electronic device 1 is enabled to execute each step of the charging method of the smart wearable device.

[0080] The above-mentioned processor 11 can be a general-purpose processor, including a central processing unit (CPU), a network processor (NP), etc.; it can also be a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components.

[0081] The above-mentioned memory 12 may include a random access memory (RAM), and may also include a non-volatile memory, such as at least one disk memory.

[0082] In practical applications, the electronic device can be a computer including all or some components such as a memory, a storage controller, one or more processing units (CPUs), a peripheral interface, an RF circuit, an audio circuit, a speaker, a microphone, an input / output (I / O) subsystem, a display screen, other output or control devices, and an external port; the computer is preferably arranged in smart glasses, a smart watch or other wearable devices.

[0083] Please refer to Figure 6 , which shows the structural schematic diagram of the smart wearable device in an embodiment of the present application. As Figure 6 shown, the present application provides a smart wearable device, and the smart wearable device 6 includes:

[0084] A device body 61, which includes a CPU.

[0085] A first charging chip 62 located on the relative two sides connected to both ends of the device body 61 and on one side of the smart wearable device;

[0086] A second charging chip 63 located on the other side of the smart wearable device;

[0087] And a battery 64 located on one or both sides of the smart wearable device.

[0088] The charging method of the smart wearable device includes:

[0089] Obtain the voltage of the battery 64, and determine the current charging stage of the battery 64 according to the voltage; the charging stage includes a pre-charging stage, a constant-current charging stage, and a constant-voltage charging stage;

[0090] In response to the current charging stage being the pre-charging stage or the constant-voltage charging stage, turn on the first charging chip 62 to charge the battery, and turn off the second charging chip 63;

[0091] In response to the current charging stage being the constant-current charging stage, turn on the second charging chip 63 to charge the battery, and turn off the first charging chip 62.

[0092] In one embodiment, the CPU of the smart wearable device and the third-party charging chip are disposed on two different circuit boards. When the smart wearable device is working, only the power supply path is provided through one end of the CPU.

[0093] Please continue to refer to Figure 2 , the AR glasses will place a battery on each side temple to increase the battery capacity. The two batteries are connected in parallel to supply power to the system. If the power supply path of the third-party charging chip is used, the electricity of the battery on the left temple will first reach the right temple, and then from the right temple to the left platform end. The impedance of the power supply trace cannot be made 0 ohm. Therefore, the power supply detour will cause some power to be consumed in the path. The third-party power supply path requires the battery to detour to increase the power supply path length, as Figure 7 shown in the power supply path of the third-party charging chip. To address the above defects, this application cancels the power supply management path of the third-party charging chip and only uses the power supply path of the platform end, that is, the CPU end, as Figure 8 shown in the power supply path of the platform-end CPU. Thus, this application adopts the power supply path of the platform charging chip, and the two batteries can be directly aggregated to supply power to the system.

[0094] The principle of the smart wearable device described in this application corresponds one-to-one with the charging method of the smart wearable device. The smart wearable device described in this application can implement the charging method of the smart wearable device described in this application. However, the implementation device of the charging method of the smart wearable device described in this application includes, but is not limited to, the structure of the smart wearable device listed in this embodiment. Any structural deformation and replacement of the prior art made according to the principle of this application are included in the protection scope of this application.

[0095] In summary, for the charging method, storage medium, device, and wearable device of the present application, during the trickle and pre-charging stages, a power management chip is used for charging; during the constant current charging stage, a third-party charging chip is used for charging; and during the constant voltage charging stage, a power management chip is used for charging. This solves the problem of temperature rise at the large current charging platform end during the constant current stage and ensures normal charging operation and system stability during the trickle, pre-charging, and constant voltage stages. Further, by improving the existing charging solution, the temperature rise experience of users when using smart wearable devices is greatly enhanced. The present application effectively overcomes various drawbacks in the prior art and has high industrial utilization value.

[0096] The above embodiments are only illustrative of the principles and effects of the present application and are not intended to limit the present application.
