[0002] As smartwatches offer increasingly more features, the demands on their battery life are also rising. Currently, the battery in most watches is housed within the watch face, and the limited space restricts battery life, making removal inconvenient. Increasing battery life inevitably increases battery size. Replacing the individual battery in the watch face with a battery integrated into the watch band would allow for a thinner and lighter smartwatch design.

[0003] However, when the battery in the watch band runs out and needs to be recharged, it also affects the use of the smartwatch. Therefore, how to provide a battery management method for a detachable watch band that can keep a smartwatch usable for a long time is an urgent problem to be solved by those skilled in the art.

The watch straps and the watch face are detachably connected.

[0031] The control module is used to control the discharge of the battery pack according to the priority scheduling instruction, so that the power of the low-power side battery is reduced to the charging threshold power.

[0032] The reminder module is used to provide a charging reminder when the battery pack's power level drops to the threshold level to be charged.

[0034] The battery packs in the two watch straps are equipped with power data; the power data is obtained by the main control chip of the watch strap through the power meter, and the watch straps are detachably connected to the watch face.

[0035] Based on the power data, the low-power battery in the watch band is determined, and a priority scheduling command corresponding to the power data is generated and sent to the main control chip of the watch band. The main control chip of the watch band controls the discharge of the battery pack according to the priority scheduling command, so that the power of the low-power battery is reduced to the charging threshold. When the power of the battery pack is reduced to the charging threshold, the main control chip of the watch band will issue a charging reminder.

[0039] The present invention also provides a smartwatch with detachable watch straps, including a watch face and at least two watch straps, wherein the watch straps are detachably connected to the watch face; the smartwatch is provided with a watch strap main control chip and a watch strap main control chip.

[0041] The system acquires the battery pack power data of the two watch straps and sends the power data to the main control chip of the watch face.

[0044] The present invention provides a battery management method for a detachable watch strap, comprising: acquiring power data of battery packs in two watch straps and sending the power data to a watch face main control chip, so that the watch face main control chip determines the low-power side battery in the watch strap based on the power data and generates a priority scheduling command corresponding to the power data and sends it to the watch strap main control chip; the watch strap is detachably connected to the watch face; controlling the discharge of the battery pack according to the priority scheduling command, so that the power of the low-power side battery is reduced to the charging threshold power; and issuing a charging reminder when the power of the battery pack is reduced to the charging threshold power.

[0045] In actual use, due to differences in discharge control strategies or strap structures, the battery packs in the two straps may have different capacities. By comparing the battery pack capacities of the two straps, the system prioritizes using the battery from the strap with the lower capacity. This allows the battery on the lower-capacity side to decrease to the charging threshold first, at which point the system will alert the user to replace the strap. However, prioritizing the lower-capacity battery maintains a certain capacity difference between the two straps. When the user is alerted to replace the lower-capacity strap, the other strap still has enough power to power the smartwatch for an extended period. This ensures the smartwatch has a longer usage time after the strap replacement alert and prevents the smartwatch from suddenly running out of power in both straps simultaneously.

[0055] The core of this invention is to provide a battery management method for a detachable watchband. In the prior art, smartwatches are increasingly equipped with additional functions, leading to higher demands on battery life. Currently, watch batteries are typically housed within the watch face, and the limited space of individual battery cells restricts battery life and makes removal inconvenient. Increasing battery life inevitably increases battery size. Replacing the individual battery in the watch face with a battery in the watchband can allow for a thinner and lighter smartwatch design. However, when the battery in the watchband runs out and needs charging, it also affects the usability of the smartwatch.

[0056] The present invention provides a battery management method for a detachable watch strap, comprising: acquiring power data of the battery packs in two watch straps and sending the power data to the main control chip of the watch face, so that the main control chip of the watch face can determine the low-power side battery in the watch strap according to the power data, and generate a priority scheduling command corresponding to the power data and send it to the main control chip of the watch strap; the watch strap and the watch face are detachably connected; the discharge of the battery pack is controlled according to the priority scheduling command so that the power of the low-power side battery is reduced to the charging threshold power; when the power of the battery pack is reduced to the charging threshold power, a charging reminder is issued.

[0057] In actual use, due to differences in discharge control strategies or strap structures, the battery packs in the two straps may have different capacities. By comparing the battery pack capacities of the two straps, the system prioritizes using the battery from the strap with the lower capacity. This allows the battery on the lower-capacity side to decrease to the charging threshold first, at which point the system will alert the user to replace the strap. However, prioritizing the lower-capacity battery maintains a certain capacity difference between the two straps. When the user is alerted to replace the lower-capacity strap, the other strap still has enough power to power the smartwatch for an extended period. This ensures the smartwatch has a longer usage time after the strap replacement alert and prevents the smartwatch from suddenly running out of power in both straps simultaneously. By encouraging the user to replace the strap, a strap rotation is implemented, thus extending the smartwatch's usability.

[0058] To enable those skilled in the art to better understand the present invention, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] Please refer to Figure 1 as well as Figure 2 , Figure 1 A flowchart illustrating a battery management method for a detachable watch strap provided in an embodiment of the present invention; Figure 2 This is a structural diagram of a smartwatch with a detachable strap.

[0060] In this embodiment of the invention, the watch includes two main structures: a watch strap and a watch face. The watch face primarily performs the main functions of a smartwatch, such as making calls and displaying the time. The watch face typically houses a watch face main control chip. The watch strap and watch face are detachably connected, meaning the watch strap is replaceable in this embodiment. The watch strap contains a battery pack and typically a watch strap main control chip, which is mainly used for data transmission and managing the discharge of the battery pack. Alternatively, both the watch face main control chip and the watch strap main control chip can be located within the watch strap; specifically, they can be master and slave chips within the watch strap, and their functions can be interchanged. Specifically, the battery management method for a detachable watch strap provided in this embodiment of the invention is specifically applied to the watch strap main control chip.

[0061] See Figure 1 as well as Figure 2 In this embodiment of the invention, the battery management method for the detachable watch strap includes:

[0062] S101: Obtain the power data of the battery packs in the two watch bands and send the power data to the main control chip of the watch face. The main control chip of the watch face determines the low power side battery in the watch band based on the power data and generates a priority scheduling instruction for the corresponding power data and sends it to the main control chip of the watch band.

[0063] In this embodiment of the invention, the watch strap and the watch face are detachably connected. When the watch strap and the watch face are connected, it means that the main control chip of the watch strap and the main control chip of the watch face are interconnected, and the two chips can communicate with each other and transmit data. In addition to the main control chip, the watch face usually contains components such as a screen and various sensors. The specific structure can be set according to the actual situation and is not specifically limited here.

[0064] In addition to the battery pack and the main control chip, the aforementioned watch band also includes a fuel gauge. The fuel gauge measures the battery pack's charge level; that is, in this step, the fuel gauge is typically used to obtain the charge level data of the battery packs in both watch bands. The main control chip can acquire and transmit this charge level data and control the battery pack's discharge. Typically, the main control chip can control the battery pack's discharge based on the battery management module to manage the battery pack's charge level. It should be noted that each watch band usually has a main control chip. When performing the following operations, the two main control chips can interact and execute together, or a primary control chip can perform the operation. In this embodiment of the invention, all main control chips are specifically described as a single unit.

[0065] In this step, the watchband main control chip obtains the battery pack power data of the watchband through the fuel gauge. Specifically, it can obtain the power data of the battery packs in two watchbands and send the power data of the two watchbands to the dial main control chip for calculation. The dial main control chip compares the power data of the two watchbands and determines that the battery pack in the watchband with the smaller power data is the low-power side battery, and the battery pack in the watchband with the larger power data is the high-power side battery. In this embodiment of the invention, the dial main control chip generates a corresponding priority scheduling instruction based on the above power data and sends the priority scheduling instruction to the watchband main control chip.

[0066] Normally, the aforementioned priority scheduling instruction corresponds to the low-charge side battery, controlling the low-charge side battery to discharge first; of course, the aforementioned priority scheduling instruction can also be an instruction for the high-charge side battery, restricting the discharge of the high-charge side battery, with the purpose of making the charge of the low-charge side battery decrease to the charging threshold charge first.

[0067] S102: Control the discharge of the battery pack according to the priority scheduling instruction, so that the power of the low-power side battery is reduced to the charging threshold power.

[0068] In this step, the main control chip of the watch band receives the aforementioned priority scheduling command. Specifically, based on the priority scheduling command, it controls the discharge of the battery packs in both watch bands through power management, so that the battery on the low-charge side is prioritized to reduce its charge level to the charging threshold. For example, by increasing the proportion of power released by the low-charge side battery, or even stopping the release of power from the high-charge side battery, the low-charge side battery's charge level can be prioritized to reduce to the charging threshold. The specific control process can be set according to the actual situation and is not specifically limited here.

[0069] S103: When the battery pack's power level drops to the threshold level for charging, a charging reminder will be issued.

[0070] In this step, when the battery pack's power level drops to the charging threshold, a charging reminder will be issued, prompting the user to charge the watch strap corresponding to the battery pack that has reached the charging threshold. This charging threshold is typically a fixed percentage, such as 20%. When the power level of a battery pack drops to 20% of its maximum capacity, the watch strap's main control chip will issue a charging reminder, prompting the user to replace the watch strap corresponding to that battery pack as soon as possible and to charge the existing strap.

[0071] Specifically, in this embodiment of the invention, each watch band can be equipped with a charging port, such as a USB interface, for charging the battery pack within the watch band. An indicator light can be provided on the surface of the watch band; this indicator light can be an LED (light-emitting diode), typically an RGB LED, meaning it can emit different colors of light. In this embodiment of the invention, different colors can be displayed based on the indicator light to provide charging reminders. For example, when the indicator light is red, it means that the corresponding battery pack's power level has dropped to the charging threshold; when the indicator light is off, it means that the corresponding battery pack's power level is above the charging threshold. Accordingly, this step can specifically involve controlling the indicator light to illuminate a preset color to remind the user of charging.

[0072] Of course, charging reminders can also be provided in other ways in this embodiment of the invention, and no specific limitation is made here. Typically, the aforementioned indicator light is located on the outer surface of the watch strap after it has been worn.

[0073] This invention provides a battery management method for a detachable watchband. By comparing the battery levels of the two watchbands, the method prioritizes using the battery from the lower-charged battery pack. This causes the battery on the lower-charged side to decrease to a charging threshold, at which point the user is alerted to replace the watchband. Prioritizing the lower-charged battery pack maintains a certain power difference between the two packs. While the user is alerted to replace the lower-charged band, the other band still has sufficient power to power the smartwatch for an extended period. This ensures the smartwatch continues to function for a longer time after the replacement alert, preventing situations where both bands simultaneously run out of power, which would otherwise affect its usability. By encouraging the user to replace the watchband with a spare, a cycle of watchband usage is achieved, thus extending the smartwatch's lifespan.

[0074] In practical use, when the two watch straps connected to the watch face have the same structure, only three watch straps need to be prepared. When the battery in one watch strap is quickly depleted to the charging threshold, the user can remove the watch strap and charge it, while replacing it with a spare watch strap to ensure uninterrupted use of the smartwatch. When the two watch straps connected to the watch face have different structures, only two pairs, a total of four watch straps, need to be prepared and can be cyclically replaced to achieve uninterrupted use of the smartwatch.

[0075] The specific details of the battery management method for a detachable watch strap provided by this invention will be described in detail in the following embodiments.

[0076] Please refer to Figure 3 as well as Figure 4 , Figure 3 A flowchart illustrating a specific battery management method for a detachable watch strap provided in an embodiment of the present invention; Figure 4 This is a schematic diagram of a specific detachable watch strap.

[0077] See Figure 3 as well as Figure 4 In this embodiment of the invention, the battery management method for the detachable watch strap includes:

[0078] S201: Obtain the power data of the battery packs in the two watch straps and send the power data to the main control chip of the watch face, so that the main control chip of the watch face can determine the low power side battery in the watch strap based on the power data.

[0079] In this embodiment of the invention, each watch strap, in addition to the above-described structure, typically includes a charging port, a connection point between the watch strap and the watch face serving as an electrical interface, an indicator light on the surface of each watch strap, and a battery pack, fuel gauge, and other structures within the watch strap. The specific details of this step have been described in detail in the above embodiments of the invention and will not be repeated here.

[0080] S202: When the power data indicates that the power of the corresponding battery pack is greater than the benchmark threshold power, the main control chip of the dial generates a first scheduling instruction to prioritize scheduling the battery on the low power side and sends it to the main control chip of the watchband.

[0081] The aforementioned baseline threshold power level is a pre-set power value that must be greater than the aforementioned charging threshold power level. In this embodiment of the invention, during the continuous consumption of the battery pack power in the watch band, different scheduling instructions can be generated based on the aforementioned baseline threshold power level. In this step, when the aforementioned power data indicates that the power levels of both battery packs are greater than the baseline threshold power level, it means that the power levels of the battery packs in both watch bands are relatively sufficient. At this time, a first scheduling instruction that prioritizes scheduling the low-power side battery will be generated. Typically, this first scheduling instruction can control the discharge amount of the low-power side battery to be greater than the discharge amount of the high-power side battery, so that the power in both watch bands is consumed, but the low-power side battery consumes power faster. Of course, the aforementioned first scheduling instruction can also be the primary control, or even only control the discharge of the low-power side battery, so that the low-power side battery discharges as quickly as possible.

[0082] S203: Control the discharge of the battery pack according to the first scheduling instruction.

[0083] In this step, after the main control chip of the watch band obtains the first scheduling instruction, it can control the discharge of the battery pack in the two watch bands or one watch band according to the content corresponding to the first scheduling instruction, so that the power of the low power side battery is reduced to the charging threshold power.

[0084] S204: When the power data indicates that the power of the corresponding battery pack is greater than the benchmark threshold power and less than the benchmark threshold power, the main control chip of the dial generates a second scheduling command to prioritize scheduling the battery on the low power side and sends it to the main control chip of the watchband.

[0085] In this step, when the aforementioned power data indicates that one battery pack has a power level greater than the baseline threshold and the other less than the baseline threshold, it means that the battery pack in one watchband has a relatively sufficient power level, while the battery pack in the other watchband has a low power level. At this time, a second scheduling instruction is generated to prioritize the lower-power battery. In practice, this second scheduling instruction can be the same as or different from the first scheduling instruction, but its purpose is to prioritize reducing the power level of the lower-power battery to the charging threshold. Specifically, the second scheduling instruction can be primarily controlled, or even only controlled, to discharge the lower-power battery, allowing it to discharge as quickly as possible; or it can control the discharge rate of the lower-power battery to be greater than that of the higher-power battery, so that both watchbands are consumed, but the lower-power battery is consumed faster. Its specific content can be set according to the actual situation and is not specifically limited here.

[0086] S205: Control the discharge of the battery pack according to the second scheduling instruction.

[0087] In this step, after the main control chip of the watch band obtains the second scheduling instruction, it can control the discharge of the battery pack in the two watch bands or one watch band according to the content corresponding to the second scheduling instruction, so that the power of the low power side battery is reduced to the charging threshold power.

[0088] S206: When the power data indicates that the power of the corresponding battery pack is less than the benchmark threshold power, and the difference between the power of the two battery packs is less than the power difference threshold, the main control chip of the dial generates a third scheduling command to prioritize scheduling the battery on the low power side and sends it to the main control chip of the watchband.

[0089] The aforementioned power difference threshold is the standard for the difference in remaining battery power between the two watch bands. When the difference in remaining battery power between the two watch bands is less than the threshold, it means that the remaining battery power of the two watch bands is relatively close; while when the difference in remaining battery power between the two watch bands is greater than or equal to the threshold, it means that the remaining battery power of the two watch bands differs significantly. In this step, when the above power data indicates that the power of both battery packs is less than the benchmark threshold, it means that the power of both battery packs in the two watch bands is low. At the same time, the difference in power between the two battery packs is less than the threshold, meaning that the remaining battery power of the two watch bands is relatively close. To avoid the situation where both watch bands run out of power at the same time, requiring the replacement of both watch bands simultaneously, resulting in insufficient watch band quantity or affecting the charging process, in this step, the main control chip of the watch face will generate a third scheduling instruction that prioritizes scheduling the battery on the lower power side, so as to limit the consumption of the remaining power of the battery on the lower power side, widen the difference in battery power between the two watch bands, and avoid the need to replace watch bands at the same time or charge both watch faces at the same time.

[0090] Normally, this third scheduling command can control the discharge of the low-charge side battery to be greater than that of the high-charge side battery, so that the battery in both bands is consumed, but the low-charge side battery is consumed faster. Of course, the above third scheduling command can also be the primary control, or even only control the discharge of the low-charge side battery, so that the low-charge side battery is discharged as quickly as possible.

[0091] S207: Control the discharge of the battery pack according to the third dispatch instruction.

[0092] In this step, after the main control chip of the watch band receives the third scheduling instruction, it can control the discharge of the battery pack in the two watch bands or one watch band according to the content corresponding to the third scheduling instruction, so that the power of the low power side battery is reduced to the charging threshold power.

[0093] S208: When the power data indicates that the power of the corresponding battery pack is less than the benchmark threshold power, and the difference between the power of the two battery packs is not less than the power difference threshold, the main control chip of the dial generates a fourth scheduling instruction to prioritize scheduling the battery with higher power and sends it to the main control chip of the watchband.

[0094] In this step, when the aforementioned power data indicates that the power levels of both battery packs are below the baseline threshold, it means that the power levels of the battery packs in both watchbands are low. Simultaneously, if the difference in power levels between the two battery packs is not less than the power difference threshold, it means that the difference in remaining power levels between the two battery packs is significant. When both battery packs have low power levels and the power difference is significant, it means that the power level of the battery on the lower side is approaching or has already reached the charging threshold. Therefore, the aforementioned fourth scheduling instruction specifically prioritizes scheduling the power of the battery on the higher side to extend the smartwatch's usage time.

[0095] S209: Control the discharge of the battery pack according to the fourth dispatch instruction.

[0096] In this step, after the main control chip of the watch band receives the fourth scheduling instruction, it can control the discharge of the battery pack in the two watch bands or one watch band according to the content corresponding to the fourth scheduling instruction, and give priority to using the power of the battery on the high-capacity side.

[0097] S210: Remind the battery on the low-battery side to charge according to the fourth dispatch instruction.

[0098] Simultaneously, in this step, receiving the fourth scheduling instruction means that the low-battery side is approaching or has already reached the charging threshold. Accordingly, in this step, a charging reminder will be sent to the low-battery side directly based on the fourth scheduling instruction.

[0099] S211: When the battery pack's power level drops to the threshold level for charging, a charging reminder will be issued.

[0100] This step is basically the same as S103 in the above-described embodiment of the invention. For details, please refer to the above-described embodiment of the invention. It will not be repeated here.

[0101] Of course, in this embodiment of the invention, after the watch band is fully charged, the main control chip of the watch band can use an indicator light to remind the user that charging is complete. For example, the indicator light can be turned on green to remind the user that charging is complete.

[0102] This invention provides a battery management method for a detachable watchband. By comparing the battery levels of the two watchbands, the method prioritizes using the battery from the lower-charged battery pack. This causes the battery on the lower-charged side to decrease to a charging threshold, at which point the user is alerted to replace the watchband. Prioritizing the lower-charged battery pack maintains a certain power difference between the two packs. While the user is alerted to replace the lower-charged band, the other band still has sufficient power to power the smartwatch for an extended period. This ensures the smartwatch continues to function for a longer time after the replacement alert, preventing situations where both bands simultaneously run out of power, which would otherwise affect its usability. By encouraging the user to replace the watchband with a spare, a cycle of watchband usage is achieved, thus extending the smartwatch's lifespan.

[0103] It should be noted that incorporating the aforementioned fuel gauge and indicator light into the watch band allows for better management of the battery pack and displays its charge level. This feature is not present in existing technologies, primarily because the battery in the watch band is solely for power supply; adding these components would increase battery consumption, negatively impacting the watch's lifespan. Furthermore, the watch itself already has a power display and control mechanism, eliminating the need for redundant features. The limited capacity of the watch band battery means that its power consumption is significant, unlike that of a power bank. However, in this embodiment of the invention, the watch band and watch face are relatively independent entities. By incorporating the fuel gauge and indicator light into the watch band, the charging and discharging process of the battery within the band can be conveniently indicated.

Therefore, the specific implementation of the battery management device with a detachable watchband can be found in the embodiment section of the battery management method with a detachable watchband mentioned above. Thus, the specific implementation can be referred to the description of the corresponding embodiments, and will not be repeated here.

[0188] The following will provide a specific application of a battery management method for detachable watch straps, the main implementation method of which is as follows:

[0189] 1. Once the watch band and dial are fastened together, the two structures are electrically connected. The fuel gauge in the watch band transmits the detected battery pack power data to the watch band's main control chip, which then transmits the data to the dial's main control chip. The dial's main control chip compares the power differences between the two battery packs and allocates different battery management schemes according to preset logic. Control commands are sent to the watch band's main control chip, which then controls the corresponding power management module to control the battery pack's discharge.

[0190] When the watch band's battery level drops below the 20% threshold, the main control chip on the watch face will control the RGB LED to emit a red light to indicate that it needs to be charged.

[0191] When both batteries have a charge level above 50%, according to the above logic, the main control chip on the watch face indirectly sends a control command to the main control chip on the watch band, prioritizing the use of the battery with the lower charge. This continues until the battery with the lower charge drops below 20%, at which point the LED on that side of the watch band flashes red, indicating that the watch band should be replaced and the battery recharged.

[0192] When one battery level is above 50% and the other is below 50%, the main control chip on the watch face indirectly sends a control command to the main control chip on the watch band, prioritizing the use of the battery on the lower-charged side. Once the lower-charged side drops below 20%, the LED on that side of the watch band flashes red, indicating that the watch band should be replaced and the battery recharged.

[0193] When both batteries are below 50% and the difference is more than 20%, the main control chip on the watch face indirectly sends a control command to the main control chip on the watch band, prioritizing the use of the battery with the higher charge. The LED on the low-charge side of the watch band flashes red, indicating that the watch band should be replaced and charged.

[0194] When both batteries are below 50% and the difference is within 20%, the main control chip on the watch face indirectly sends a control command to the main control chip on the watch band, prioritizing the use of the battery on the side with the lower charge. Once the charge on that side drops below 20%, the LED on that side of the watch band will flash red, indicating that the watch band should be replaced and charged.

[0195] When the battery pack charge on either side falls below 20%, the corresponding LED indicator on the watch band will light up red, indicating that charging is required. When the watch band is removed, the power meter transmits the battery pack charge data to the watch band's main control chip. Once the main control chip determines that the charge is below 20%, it will trigger the RGB LED to emit red light, indicating that charging is in progress. When the watch band is fully charged, the main control chip will control the RGB LED to emit green light, indicating that charging is complete. The aforementioned 20% is the selectable threshold charge level, and the aforementioned 50% is the selectable baseline threshold charge level. Of course, these values ​​can be set according to actual needs and are not specifically limited here.
