Description

Technical Field

[0001] The present invention relates to the technical field of charging control, and particularly to a charging control method for a wireless device, a wireless device, and a wireless device charging control system.

Background Art

[0002] Currently, with the increasing use of smart phones, the wireless device market is booming. For example, wireless earphones. The charging case of the wireless device is a new application. As a backup power source for the wireless device, it solves the problem of the usage time of the wireless device. At the same time, as the charging case of the wireless device, it is closely related to the user's operation.

[0003] When the wireless device is placed in the charging case for charging, it will disconnect from the smart phone. And when the wireless device is taken out of the charging case, it will resume connection with the smart phone, that is, complete the reconnection, and receive and send the audio signal of the smart phone through the wireless device.

[0004] In the related art, when the wireless device is placed in the charging case for charging, there are only two contacts for the positive and negative power supplies between the wireless device and the charging case. The two endpoints of the charging case are the power output endpoints, and the two endpoints of the wireless device are the power input endpoints.

[0005] However, for the currently used wireless device and charging case, when the battery of the charging case is low on power, the output voltage of the charging case drops immediately. The wireless device cannot distinguish whether it is the charging case that loses power or the wireless device is taken out of the charging case through the two positive and negative power contact points. The wireless device will perform a certain action, such as reconnecting to the paired smart phone, etc., which affects the use of the smart phone, and at the same time causes power consumption of the wireless device, etc., and cannot feedback the power situation of the charging case, resulting in a poor user experience.

Specific Embodiments

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0056] The embodiments, implementation manners and technical features in the present invention can be combined with each other without conflict. The step numbers in the present invention are only for illustration and do not constitute a limitation on the step sequence.

[0057] The present invention provides a method for controlling wireless device charging, which is applied to a wireless device and a charging case for charging the wireless device.

[0058] Specifically, the wireless device includes a power input terminal, a first ground terminal and a detection terminal; the charging case includes a power output terminal, a second ground terminal connection and a measured terminal. Among them, the power input terminal is used to connect to the power output terminal, the first ground terminal is used to connect to the second ground terminal, the detection terminal is used to connect to the measured terminal, and the measured terminal is used to output the battery voltage of the charging case.

[0059] The wireless device includes at least one of a smart watch, smart glasses, a Bluetooth headset, and a Wi-Fi headset. In this implementation manner, the wireless device is a wireless earphone, that is, the wireless device is a Bluetooth headset or a Wi-Fi headset.

[0060] Please refer Figure 1 As shown, a method for controlling wireless device charging provided by the present invention includes the following steps:

[0061] Step S1: The wireless device continuously monitors the voltage value of the detection end, compares the voltage value of the detection end with a threshold voltage, and controls the wireless connection between the wireless device and its matched terminal device according to the comparison result.

[0062] Among them, the continuous monitoring is uninterrupted continuous monitoring. Of course, in order to reduce the power consumption of the wireless device, it can also be intermittent monitoring.

[0063] In this embodiment, the threshold voltage includes at least one of the following: a first threshold voltage, a second threshold voltage, and a third threshold voltage. Among them, the first threshold voltage is greater than the second threshold voltage, and the third threshold voltage is greater than or equal to the second threshold voltage. Preferably, the first threshold voltage is greater than or equal to the third threshold voltage.

[0064] In this embodiment, by comparing the voltage value of the detection end with the threshold voltage, the state of the wireless device in the charging case can be determined. This state includes a low-power state, a pulled-out state, and a placed state. Specifically:

[0065] When the voltage value of the detection end is less than or equal to the first threshold voltage and greater than the second threshold voltage, it is confirmed that the charging case is in a low-power state; and / or,

[0066] When the voltage value of the detection end is less than or equal to the second threshold voltage, it is confirmed that the wireless device is in a pulled-out state; and / or,

[0067] When the voltage value of the detection end is greater than the third threshold voltage, it is confirmed that the wireless device is in a placed state.

[0068] Among them, preferably, the first threshold voltage is greater than or equal to the third threshold voltage, so as to avoid the situation that when the battery power of the charging case is between the first threshold voltage and the third threshold voltage, the placed state cannot be detected. The placed state is the state where the power input end is connected to the power output end, the first ground end is connected to the second ground end, and the detection end is connected to the measured end.

[0069] In this embodiment, the first threshold voltage can be determined according to the battery power of the wireless device. For example, when the battery power of the charging case is insufficient to fully charge the device, the wireless device initiates a reconnection and sends a charging reminder. The wireless device judges the power required for charging based on its own power. The power required for charging corresponds to the first threshold voltage, and it is compared with the battery voltage of the collected charging case. If the power of the charging case is not enough to fully charge the device, it reconnects to remind the user.

[0070] Please refer to Figure 2 as shown below, and the following will be described in detail with examples:

[0071] An embodiment of a method for controlling wireless device charging provided by the present invention includes the following steps:

[0072] Step S01: The wireless device determines its own working state, and the working state includes a charging state and a standby state. The wireless device enters Step S02 or Step S03 according to the working state.

[0073] Step S02: When the wireless device is in the charging state, the wireless device selects an analog-to-digital conversion module to compare the voltage value at the detection end with a threshold voltage.

[0074] Step S03: When the wireless device is in the standby state, the wireless device selects a comparator to compare the voltage value at the detection end with a threshold voltage.

[0075] Regarding the above steps, it should be noted that the analog-to-digital conversion module includes an analog-to-digital converter and a comparison circuit, and the comparison circuit can be a numerical comparator; preferably, when the wireless device is in the charging state, the wireless device uses the analog-to-digital conversion module to compare the voltage value at the detection end with the threshold voltage to obtain a specific power value. When the wireless device is in the standby state, the wireless device uses a comparator (such as a voltage comparator) to compare the voltage value at the detection end with the threshold voltage to reduce power consumption; the wireless device checks the voltage value at the detection end through the comparator or the analog-to-digital conversion module and determines whether the power of the charging case is sufficient to charge the wireless device, so that the user can understand the situation in time and thus has a good user experience.

[0076] Step S1: The wireless device monitors the voltage value at the detection end in real time, compares the voltage value at the detection end with a threshold voltage, and controls the wireless connection between the wireless device and its matching terminal device according to the comparison result.

[0077] In Step S1, the method for controlling wireless device charging includes different steps, as detailed below:

[0078] When the charging case is in a low-power state. The method for controlling wireless device charging specifically includes the following steps:

[0079] Step S11: When it is confirmed for the Mth time that the charging case is in a low-power state, control the wireless device to be wirelessly connected to the terminal device. M is a natural number greater than zero. Here, M can be once or multiple times. The Mth time refers to a certain time when it has been in the low-power state all the time. If the wireless device returns from the low-power state to a non-low-power state, the next Mth time is recalculated. Or if the wireless device is pulled out of the charging case, the next Mth time is recalculated. This avoids repeated reconnecting when in a low-power state for a long time.

[0080] When the charging case is confirmed to be in a low - power state for the Mth time, the following steps are further included:

[0081] Step S11a: After the wireless device is wirelessly connected to the terminal device, it sends the battery power information of the charging case to the terminal device. Among them, the battery power information includes a low - power state or a specific power value. In this way, the user can know the battery power information of the charging case, thus improving the user experience.

[0082] Step S11b: The wireless device disconnects the wireless connection with the terminal device. Thus, it can avoid being in a re - connection state all the time, which affects the use of terminal devices such as mobile phones by users.

[0083] Step S12: Control the charging between the charging case and the wireless device to stop. The function of step S12 is for secondary protection. In addition, it can also reduce the risk of misjudging as being unplugged when the battery runs out. Of course, this method is optional. It can be adopted when the standard for judging that the charging case is in a low - power state, that is, the first voltage threshold is set relatively low. However, if the first voltage threshold is set relatively high, it is not suitable for use, otherwise it may affect the charging ability.

[0084] When the wireless device is in the unplugged state. The wireless device charging control method specifically includes the following steps:

[0085] Step S13: The wireless device sends the battery power information of the charging case that it detected and stored for the Nth time before to the terminal device. N is a natural number greater than zero. Among them, the value of N is calculated according to the time interval for collecting the battery voltage of the charging case. In fact, the power - off speed of the wireless device when unplugged is not very slow. On the contrary, the power - off of the charging case should be slower when it runs out of power. Based on this, the value of N can be considered as follows: If the interval is very short, it may detect the voltage during the slow - decline stage of the voltage during the unplugging process, resulting in misjudging as being out of power. Therefore, N should be taken several more times forward, such as 5 times. If the interval is long, then N may be the previous detection.

[0086] Step S14: When it is confirmed that the wireless device is in the unplugged state, control the wireless device to be wirelessly connected to the terminal device and control the wireless device to start running. Among them, the wireless device being wirelessly connected to the terminal device in step S11 can be to only turn on some internal circuit modules of the wireless device, while when unplugged in step S14, all internal circuit modules of the wireless device need to be turned on, that is, the wireless device works normally.

[0087] When the wireless device is in the inserted state. The wireless device charging control method specifically includes the following steps:

[0088] Step S15: The wireless device wirelessly transmits the obtained battery power information of the charging case to the terminal device, enabling the user to timely understand the situation through the terminal device and providing a good user experience.

[0089] Step S16: Control the wireless device to disconnect the wireless connection with the terminal device, thus avoiding affecting the user's use of the terminal device and further controlling the wireless device to enter a charging state, shut down, or sleep, thereby saving energy consumption. The present invention also provides a wireless device, including a processor and a memory, where the processor is used to execute the steps in the above-mentioned wireless device charging control method.

[0090] The present invention also provides a wireless device charging control system 100, including the above-mentioned wireless device 1 and a charging case 2 that houses the wireless device 1 and charges it.

[0091] Specifically, please refer to Figure 3 As shown, the present invention also provides a wireless device charging control system 100, including a wireless device 1 and a charging case 2 for charging the wireless device 1.

[0092] The wireless device 1 includes at least one of a smart watch, smart glasses, Bluetooth headset, and Wi-Fi headset. In this embodiment, the wireless device 1 is a wireless earphone, that is, the wireless device is a Bluetooth headset or a Wi-Fi headset. The wireless earphone is data-connected to the terminal device. The terminal device can be a smart phone or a tablet computer. Among them, when the wireless device 1 is a Bluetooth headset, the wireless device 1 is connected to the terminal device via Bluetooth; when the wireless device 1 is a Wi-Fi headset, the wireless device 1 is connected to the terminal device via Wi-Fi.

[0093] The wireless device 1 includes: a power input terminal IO1, a first ground terminal IO2, a detection terminal IO3, a wireless device battery 11, a charging module 12, and a battery power detection module 13.

[0094] Specifically, the power input terminal IO1, the first ground terminal IO2, and the detection terminal IO3 can all be used as input ports, and the detection terminal IO3 can also be an output port, that is, IO3 can be a bidirectional communication port.

[0095] The wireless device battery 11 is used to provide a power supply voltage. Define the power supply voltage provided by the wireless device battery 11 as V11, and the power supply voltage V11 is used for the internal circuit of the wireless device 1.

[0096] The charging module 12 is used to process the input voltage of the charging case 2 and charge the wireless device battery 11.

[0097] The power detection module 13 is used to monitor the voltage value of the detection terminal IO3 in real time, and compare the voltage value of the detection terminal IO3 with the threshold voltage VTH.

[0098] The control module 14 is used to control the wireless connection between the wireless device 1 and its matched terminal device 3 according to the comparison result. Wherein, the threshold voltage is defined as VTH. The power detection module 13 includes an analog-to-digital conversion module 131 and a comparator 132. Both the analog-to-digital conversion module 131 and the comparator 132 are used to judge the power level of the charging case 2.

[0099] It should be noted that the power detection module 13 further includes the analog-to-digital conversion module 131 and the comparator 132, and the comparator 132 can be a numerical comparator or a voltage comparator.

[0100] Definition: The first threshold voltage is VTH1, the second threshold voltage is VTH2, and the third threshold voltage is VTH3.

[0101] The threshold voltage VTH includes at least one of the following: the first threshold voltage VTH1, the second threshold voltage VTH2, and the third threshold voltage VTH3.

[0102] Preferably, the first threshold voltage VTH1 is greater than the second threshold voltage VTH2;

[0103] Preferably, the third threshold voltage VTH3 is greater than or equal to the second threshold voltage VTH2. The analog-to-digital conversion module 131 is used to convert the voltage value of the charging case battery 21 into a digital value in real time, and the digital value is used for comparison with the first threshold voltage VTH1, the second threshold voltage VTH2, and the third threshold voltage VTH3 respectively.

[0104] The comparator 132 is used to compare the voltage value of the charging case battery 21 with the first threshold voltage VTH1, the second threshold voltage VTH2, and the third threshold voltage VTH3 in real time respectively.

[0105] Preferably, the first threshold voltage VTH1 is greater than or equal to the third threshold voltage VTH1.

[0106] The charging case 2 is used to accommodate the wireless device 1 and charge it. Specifically, the charging case 2 includes a power output terminal IO4, a second ground terminal IO5, a measured terminal IO6, a charging case battery 21, and a boost module 22.

[0107] The power output terminal IO4, the second ground terminal IO5, and the measured terminal IO6 can all be used as output ports. Among them, the detection terminal IO6 can also be an input port, that is, IO6 can be a bidirectional communication port.

[0108] The charging case battery 21 is used to provide the power supply voltage V21 of the charging case 2 as the voltage to be measured. It is defined that the power supply voltage provided by the charging case battery 21 for the charging case 2 is V21.

[0109] The boost module 22 is used to boost the voltage of the charging case battery.

[0110] Among them, the wireless device 1 is placed into the charging case 2, so that the power input terminal IO1 is connected to the power output terminal IO4. The first ground terminal IO2 is connected to the second ground terminal IO5. The detection terminal IO3 is connected to the measured terminal IO6.

[0111] During the use of the wireless device charging control system 100, when the wireless device 1 is loaded into the charging case 2 and needs to be charged, after the boost module 22 boosts the voltage of the wireless device battery 11, it charges the wireless device battery 11 through the sequentially connected power output terminal IO4, the power input terminal IO1, the charging module 12, and the wireless device battery 11. Among them, when the wireless device 1 is charging, the power detection module 13 detects the power of the charging case battery 21 in real time by sequentially connecting the detection terminal IO3, the measured terminal IO6, and the charging case battery 21.

[0112] In this embodiment, by comparing the voltage value of the detection terminal IO3 with the threshold voltage VTH, the state of the wireless device 1 in the charging case 2 can be determined. This state includes a low power state, a pulled-out state, and a placed state. Specifically:

[0113] When the power detection module 13 detects that the voltage value of the detection terminal IO3 is less than or equal to the first threshold voltage VTH1 and greater than the second threshold voltage VTH2, it is confirmed that the charging case 2 is in a low power state. The determination of the low power state enables the user to know that the charging case 2 has a low power, thus improving the user experience.

[0114] When the power detection module 13 detects that the voltage value of the detection terminal IO3 is less than or equal to the second threshold voltage VTH2, it is confirmed that the wireless device 1 is in a pulled-out state. The determination of the pulled-out state enables the user to know the accurate state of the wireless device 1, thus improving the user experience.

[0115] When the power detection module 13 detects that the voltage value of the detection terminal IO3 is greater than the third threshold voltage VTH3, it is confirmed that the wireless device 1 is in the inserted state. In this embodiment, when it is confirmed that the wireless device 1 is in the inserted state, the wireless connection between the wireless device 1 and the terminal device 3 is controlled to be disconnected. The inserted state allows the user to accurately determine that the wireless device 1 has not been removed from the charging case 2 or that the charging case 2 is not out of power due to insufficient battery, thus providing a good user experience.

[0116] Preferably, the first threshold voltage is greater than or equal to the third threshold voltage, so as to avoid the failure to detect the insertion when the battery power of the charging case is between the first threshold voltage and the third threshold voltage.

[0117] In a feasible implementation, when it is confirmed for the Mth time that the wireless device is in the low-power state, the control module 14 is used to control the wireless device 1 to be wirelessly connected to the terminal device 3. M is a natural number greater than zero, and the battery power information of the charging case 2 is sent to the terminal device, and then the wireless connection with the terminal device 3 is disconnected; and / or,

[0118] When it is confirmed that the wireless device 1 is in the pulled-out state, the control module 14 is used to control the wireless device 1 to be wirelessly connected to the terminal device 3, and send the battery power information of the charging case 2 detected and stored for the Nth time before to the terminal device 3. N is a natural number greater than zero, and the wireless device 1 is controlled to be powered on and run; and / or,

[0119] More preferably, when it is confirmed that the wireless device 1 is in the inserted state, the control module 14 is used to control the wireless device 1 to wirelessly send the obtained battery power information of the charging case 2 to the terminal device 3, and then control the wireless device 1 to disconnect the wireless connection with the terminal device 3.

[0120] In a feasible implementation, the first threshold voltage VTH1 is determined according to the battery power of the wireless device 1.

[0121] Compared with the prior art, the wireless device charging control method of the present invention includes the following steps: The wireless device monitors the voltage value of the detection end in real time, compares the voltage value of the detection end with a threshold voltage, and controls the wireless connection between the wireless device and its matching terminal device according to the comparison result. Among them, the voltage value of the detection end is compared with the threshold voltage to confirm that the charging box is in a low power state; and / or, to confirm that the wireless device is in a pulled-out state; and / or, to confirm that the wireless device is in a placed state. Thus, the wireless device charging control method can accurately determine whether the wireless device has been taken out of the charging box or the charging box has insufficient power and loses power. At the same time, the wireless device monitors the voltage value of the detection end in real time, so that the information of this voltage value can be displayed through the terminal device. Therefore, the method provided by the present invention makes the detection more accurate when the wireless device is pulled out or put into the charging box, and can display the power of the charging box on the terminal device such as a mobile phone that matches the wireless device, and give a reminder when the charging box has low power, so that the wireless device charging control method, wireless device and wireless device charging control system of the present invention have a good user experience.

[0122] The above are only the embodiments of the present invention. It should be noted here that for those of ordinary skill in the art, without departing from the inventive concept of the present invention, improvements can still be made, but these all belong to the protection scope of the present invention.
