[0019] To solve the above technical problems, the present disclosure proposes a charging circuit.

[0020] Figure 1 is a circuit structure schematic diagram of a charging circuit according to an embodiment of the present disclosure.

[0021] As Figure 1 shown, the circuit comprises:

[0022] a main battery 110 for powering an electronic device;

[0023] a backup battery 120;

[0024] a first switch 130, one end of the first switch 130 being connected to the backup battery 120, and the other end being connected to a load inside the electronic device;

[0025] a control module 140, in a case where an instruction of ejecting the main battery 110 from the electronic device is received, the control module 140 closes the first switch 130, and disconnects the main battery 110 from the electronic device;

[0026] a charging module 150 connected to the main battery 110 and the backup battery 120, for charging the main battery 110 and / or the backup battery 120.

[0027] In some embodiments, the electronic device comprises a movable electronic device.

[0028] For example, the movable electronic device can be a robot, a sweeper, a mechanical pet, etc. For the convenience of understanding and description, the scheme of the present disclosure will be introduced hereinafter taking a mechanical pet as an example.

[0029] In some embodiments, the circuitry is located within the mechanical pet.

[0030] The circuitry is located inside the mechanical pet, which can be electrically driven, such as for moving or making sounds.

[0031] In some embodiments, the main battery 110 is used to power the mechanical pet.

[0032] like Figure 1 As shown, the main battery 110 can be connected to the internal load of the mechanical pet, which is powered by the main battery.

[0033] In some embodiments, one end of the first switch 130 is connected to the backup battery 120, and the other end is connected to the mechanical pet, such as a load inside the mechanical pet.

[0034] With the first switch closed, the backup battery 120 can supply power to the mechanical pet's load, thereby enabling the mechanical pet to be powered.

[0035] In some embodiments, when the control module 140 receives an instruction to eject the main battery 110 from the mechanical pet, it closes the first switch 130 to disconnect the main battery 110 from the mechanical pet.

[0036] Since the mechanical pet is battery-powered, when the main battery 110 has low power, it can be replaced with another main battery. Generally, replacing the main battery will disconnect the main battery from the mechanical pet, causing the mechanical pet to stop working due to power loss, or to automatically shut down and wait for power to be restored before restarting.

[0037] According to an embodiment of this disclosure, when the control module 140 receives an instruction to eject the main battery 110 from the electronic device, it can first close the first switch 130 to connect the backup battery to the electronic device, and then disconnect the main battery 110 from the electronic device to proceed with the replacement of the main battery 110. In this case, during the replacement of the main battery, the load of the electronic device can be switched from being powered by the main battery 110 to being powered by the backup battery 120. Therefore, when the main battery is ejected, the electronic device is powered by the backup battery 120, thereby avoiding power loss of the electronic device during the replacement of the main battery.

[0038] In some embodiments, the instruction of ejecting the main battery 110 from the mechanical pet can be triggered by a user. For example, when the user manually opens the battery slot of the main battery 110, or when the user remotely sends an instruction to the mechanical pet to open the battery slot of the main battery 110, the instruction of ejecting the main battery 110 from the mechanical pet is generated, and the control module 140 receives the instruction of ejecting the main battery 110 from the mechanical pet.

[0039] In some embodiments, the instruction of ejecting the main battery 110 from the mechanical pet can be triggered by the pet nest of the mechanical pet. For example, the mechanical pet can automatically return to the pet nest when it senses that the main battery 110 needs to be charged, and the pet nest can send an instruction to the mechanical pet to open the battery slot of the main battery 110 when it senses that the mechanical pet has returned to the location for replacing the main battery, thereby triggering the mechanical pet to generate the instruction of ejecting the main battery 110 from the mechanical pet, and the control module 140 receives the instruction of ejecting the main battery 110 from the mechanical pet.

[0040] In some embodiments, the capacity of the backup battery 120 is less than that of the main battery 110.

[0041] The capacity and voltage of the backup battery 120 can be less than those of the main battery 110. The scenario for using the backup battery 120 is when the main battery 110 is ejected for replacement, so the backup battery 120 is mainly used to keep the mechanical pet in an electric state during the replacement process. Although the space inside the mechanical pet is relatively large and there is no problem of insufficient space, based on the consideration of the cost and quality of the mechanical pet, a backup battery 120 with a smaller capacity than the main battery 110 can be selected to save costs.

[0042] In some embodiments, during the period when the backup battery 120 supplies power to the mechanical pet, the mechanical pet works with a power lower than the first threshold.

[0043] The backup battery 120 has a small capacity and voltage, and is generally only used to temporarily power the mechanical pet during the replacement of the main battery 110, and is not a regular power supply option, therefore, the mechanical pet can work with a lower power to avoid consuming the backup battery 120 too quickly.

[0044] In some embodiments, the main battery 110 is connected to the mechanical pet through the second switch.

[0045] The control module 140, in the case of receiving an instruction of ejecting the main battery 110 from the mechanical pet, can first close the first switch 130 to connect the backup battery 120 with the mechanical pet, so that the mechanical pet can be powered by the backup battery 120, then control the second switch to be opened to disconnect the main battery 110 from the mechanical pet, switch the power supply of the mechanical pet from the main battery 110 to the backup battery 120, and finally eject the main battery 110 to facilitate the replacement of the main battery 110.

[0046] In some embodiments, the second switch can be a contact switch arranged in the battery slot of the main battery 110.

[0047] The main battery 110 is connected to the mechanical pet through the contact switch in the battery slot. The control module 140 ejects the main battery 110 from the battery slot, so that the main battery 110 is separated from the contact, the contact switch is opened, and the connection between the main battery 110 and the mechanical pet is disconnected.

[0048] In some embodiments, the control module 140 is further configured to, in the case of receiving an instruction of loading the main battery 110, connect the main battery 110 with the mechanical pet and disconnect the first switch 130.

[0049] After the main battery 110 is loaded into the battery slot, the control module 140 can connect the main battery 110 with the mechanical pet and disconnect the first switch to disconnect the backup battery 120 from the mechanical pet, and switch the power supply of the mechanical pet from the backup battery 120 back to the main battery 110.

[0050] In some embodiments, connecting the main battery 110 with the mechanical pet includes closing the second switch.

[0051] If the second switch is disconnected before the main battery 110 is ejected, the control module 140 can close the second switch after the main battery 110 is loaded. In some embodiments, the second switch is a contact switch, and when the main battery 110 is loaded into the battery slot, the main battery contacts the contact to connect the main battery 110 with the mechanical pet.

[0052] Figure 2 is a schematic diagram of a circuit of a mobile electronic device according to an embodiment of the present disclosure.

[0053] As Figure 2 shown, in some embodiments, the circuit further includes a charging module for charging the main battery 110 and / or the backup battery 120, the charging module including at least one of: a wired charging module 210; a wireless charging module 220; a radio frequency charging module 230.

[0054] The charging module can charge the main battery 110 and / or the backup battery 120. It should be noted that the mechanical pet can have at least one of the three charging modules described above.

[0055] When the main battery 110 of the mechanical pet has a low power (e.g., lower than a power threshold), instead of replacing the main battery 110, the main battery 110 can be charged based on the charging module. In some embodiments, the charging module can charge the main battery 110 and / or the backup battery 120.

[0056] It should be noted that, Figure 2 The examples in FIG. 10 only show the connection structure between the charging module and the main battery 110, and only show the relative connection relationship, not the specific circuit diagram, and part of the specific circuit diagram has been omitted.

[0057] In some embodiments, the charging module includes a wired charging module, and the wired charging module includes a voltage converter, one end of the voltage converter being connected to an external power supply, and the other end being connected to the main battery and the backup battery.

[0058] In some embodiments, the wired charging module 210 is configured to determine the charging current for the mechanical pet according to a model obtained through machine learning.

[0059] For example, the model can be determined through a neural network and a genetic algorithm. In the training phase of the model, at least one of the temperature of the mechanical pet, the power consumption of the mechanical pet, the impedance of the main battery, and the aging state of the main battery is input to the model, and the corresponding charging current is given. The model is configured to determine the charging current of the mechanical pet according to the input.

[0060] Since the input data of the model is difficult to exhaust, there is a slight change in the value, so it is also difficult to determine the charging current by directly presetting the corresponding relationship table of the input and the charging current of the model. Through the model obtained through machine learning, the target charging current corresponding to the input can be determined in the case of giving any input, so as to realize the adaptive adjustment of the charging current of the mechanical pet based on the change of its own situation. It should be noted that the target charging current is the current determined based on the charging time, power consumption, heating condition and other aspects, which can be reflected by the value of the charging current in the sample in the training model stage.

[0061] In some embodiments, the input of the model includes at least one of the following: the temperature of the mechanical pet, the power consumption of the mechanical pet, the impedance of the main battery, and the aging state of the main battery.

[0062] The mechanical pet can be provided with a temperature sensor inside, and the wired charging module 210 can obtain the parameters of the temperature sensor to determine the temperature of the mechanical pet and as an input (one of) to determine the charging current; the power consumption of the mechanical pet can be determined according to the load; the impedance of the main battery and the aging state of the main battery are related to the main battery, which can be determined according to the battery management module of the main battery. As an example, as the temperature of the mechanical pet increases, the charging current can first increase and then decrease; the greater the power consumption of the mechanical pet, the greater the charging current; the greater the impedance of the main battery, the more serious the aging of the main battery, and the greater the corresponding charging current.

[0063] In some embodiments, the charging module includes a wireless charging module, which includes a transmitting coil, a receiving coil, and a voltage converter; wherein the receiving coil is disposed on the electronic device, for receiving a charging signal according to electromagnetic transformation on the transmitting coil to generate a charging current, and one end of the voltage converter is connected to the receiving coil and the other end is connected to the main battery and the backup battery.

[0064] In some embodiments, the wireless charging module further includes a relay coil disposed between the receiving coil and the transmitting coil, which is activated when the charging signal received by the receiving coil is less than a preset threshold, for enhancing the charging signal.

[0065] The wireless charging module can further include a receiving coil disposed inside the mechanical pet, and a wireless charging coil disposed in the charging base. When the mechanical pet receives a wireless charging instruction, it can align the receiving coil with the wireless charging coil in the charging base. The wireless charging coil can generate a varying magnetic field under the action of alternating current. Based on the principle of electromagnetic induction, the receiving coil generates an induced current, which in turn charges the main battery 110.

[0066] However, the positioning of the mechanical pet can have errors, and it is difficult to align the receiving coil and the wireless charging coil in some scenarios, resulting in a large distance between the receiving coil and the wireless charging coil, and the current / voltage for charging sensed by the receiving coil is correspondingly small, which is difficult to meet the charging needs of the main battery 110. In this case, the relay coil located between the receiving coil and the wireless charging coil can be activated. The relay coil can generate an induced current based on the wireless charging coil, thereby forming a varying magnetic field, and then causing the receiving coil to generate an induced current. The relay coil can increase the induction distance of the receiving coil. In the case where the mechanical pet is not aligned with the wireless charging coil and the charging signal is less than a preset threshold, the relay coil is activated to enhance the charging signal.

[0067] Since there is loss in electromagnetic induction, the quality requirement of the relay coil is high, and the loss is small. In some embodiments, in the case that the charging signal received by the wireless charging module is greater than or equal to a preset threshold, the relay coil is disabled to reduce energy loss.

[0068] In some embodiments, the mechanical pet can prefer to use the wireless charging module 220 to charge the main battery 110 when it enters the rest mode.

[0069] The rest mode can be triggered based on an instruction issued by the user, for example, recognizing the voice instruction "back to the nest and rest" issued by the user, triggering the mechanical pet to return to the charging base, and then using the wireless charging module 220 to charge the main battery 110; it can also be triggered at a preset time period, for example, entering the rest mode after 12 o'clock every night.

[0070] In some embodiments, the charging module includes a radio frequency charging module 230, which includes a transmitting antenna, a receiving antenna, and a rectifier module; wherein the receiving antenna is disposed on the electronic device, for receiving radio frequency signals sent by the transmitting antenna and converting them into charging signals; one end of the rectifier module is connected to the receiving antenna, and the other end is connected to the main battery and the backup battery.

[0071] In some embodiments, the transmitting antenna is disposed in the charging station of the electronic device, for transmitting radio frequency signals; wherein the radio frequency signals are signals sent by the charging station towards the position of the electronic device after determining the position.

[0072] The charging base can determine the position of the mechanical pet and send radio frequency signals in the direction of its position. The receiving antenna on the mechanical pet can convert the radio frequency signals into charging signals after receiving the radio frequency signals, for charging the main battery 110.

[0073] For the user, if the mechanical pet is out of power during use and has to return to the charging base for charging, the user is forced to temporarily separate from the mechanical pet and has to wait for a long time before the mechanical pet can continue to move, which is a relatively poor user experience. Unlike the wireless charging module 220 and the wired charging module 210, the radio frequency charging module 230 can charge the mechanical pet while the mechanical pet is moving within a certain range. Thus, the movement of the mechanical pet is not interrupted due to the charging requirement, the mechanical pet can move away from the charging base for a long time, charging to a certain extent is achieved outside the charging base, the frequency and duration of the mechanical pet returning to the charging base are reduced, and a good user experience is provided. Based on the transmission capability of the radio frequency signal of the charging base, the certain range can be the space of at least one room. The radio frequency charging module 230 is used for charging, has good anti-deviation characteristics, and the mechanical pet can be remotely charged during movement.

[0074] In some embodiments, the receiving antenna is arranged in the tail of the mechanical pet.

[0075] Since the tail of the mechanical pet is located outside the main body of the mechanical pet, the receiving antenna arranged in the tail of the mechanical pet can have better clearance and be more conducive to receiving the radio frequency signal, and the strength of the radio frequency signal received by the receiving antenna arranged in the tail can be relatively high.

[0076] In some embodiments, there is a priority order among the wired charging module 210, the wireless charging module 220, and the radio frequency charging module 230.

[0077] When the mechanical pet meets the charging conditions of multiple charging modules at the same time, which charging module to use for charging can be determined based on the priority order. For example, when the mechanical pet uses the wireless charging mode, the mechanical pet can also receive the radio frequency signal sent by the charging base and meet the charging condition of the radio frequency charging module, but since it is difficult to use two different charging modules to charge the mechanical pet at the same time, which charging module to use for charging can be determined based on the set priority order.

[0078] In some embodiments, the priority order is: the wired charging module 210, the wireless charging module 220, and the radio frequency charging module 230.

[0079] As an example, the charging modules can be sorted according to how much energy is lost during charging. Relatively speaking, the wired charging module 210 has the smallest charging loss, and thus has a higher priority.

[0080] In some embodiments, the mechanical pet can determine the charging current of multiple charging modes respectively, and use the charging module corresponding to the charging mode with the largest charging current for charging.

[0081] For example, in a scenario where the mechanical pet satisfies both wireless charging and radio frequency charging, the mechanical pet can obtain the charging current of the wireless charging and the charging current of the radio frequency charging respectively, and select the charging mode with the larger charging current for charging by comparison.

[0082] Figure 3 is a schematic diagram of a circuit of a mobile electronic device according to an embodiment of the present disclosure.

[0083] As shown in Figure 3 , the mobile electronic device can simultaneously have a wired charging module, a wireless charging module, and a radio frequency charging module. In the embodiment shown in Figure 3 , since multiple charging modules are simultaneously present in the circuit, the circuit also includes an MCU (Microcontroller Unit) for controlling the switches on the three charging module lines to control the charging mode adopted by the mobile electronic device.

[0084] In some embodiments, the control of the switches on the three charging module lines can also be achieved by a control module.

[0085] In some embodiments, the wired charging module includes a voltage converter (Buck Boost).

[0086] The voltage converter can step up or step down the provided voltage to output a determined charging voltage or a determined charging current. For example, the charging current can be determined by a machine learning model, and then the voltage converter is used for voltage conversion to obtain a determined charging current.

[0087] In some embodiments, the radio frequency charging module includes a receiving antenna, an impedance matching module, and a rectifier module.

[0088] The impedance matching module is used to ensure good impedance matching between the transmission line and the receiving antenna, and the rectifier module is used to convert the received radio frequency signal into a voltage for charging the main battery.

[0089] In some embodiments, the wireless charging module includes a relay coil, a receiving coil, and a voltage converter. The functions and roles of each structure are described in the above embodiments and will not be repeated here.

[0090] Based on the embodiment shown in Figure 3 , when the mobile electronic device replaces the main battery, the first switch can be closed based on the control module to use the backup battery for power supply during the battery replacement process, thereby avoiding power failure of the mobile electronic device. On the other hand, the mobile electronic device can simultaneously use multiple charging modes to charge the main battery, and the most suitable charging mode can be used in various scenarios.

[0091] The present disclosure provides a movable electronic device, which is a mechanical pet comprising the circuit according to any one of the above.

[0092] In some embodiments, the movable electronic device can be a mechanical pet.

[0093] Figure 4 is a structural schematic diagram of a mechanical pet according to an embodiment of the present disclosure.

[0094] Figure 4 The mechanical pet shown is a mechanical dog, which only serves as an example, and the mechanical pet simultaneously has three charging modules, but this should not be construed as a limitation of the present disclosure, and in fact, the mechanical pet can have any combination of the wired charging module, the wireless charging module, and the radio frequency charging module.

[0095] In some embodiments, the circuit of the mechanical pet comprises a battery replacement module.

[0096] The battery replacement module comprises a backup battery 120, a first switch 130, and a control module 140.

[0097] Based on the battery replacement module, in the case that the main battery 110 has a low power level, the mechanical pet can replace another main battery with a higher power level, and ensure that the backup battery 120 supplies power to the mechanical pet during the battery replacement process, so as to ensure that the mechanical pet does not lose power.

[0098] In some embodiments, the mechanical pet comprises a mechanical dog.

[0099] Figure 5 is a structural schematic diagram of a charging base of a mechanical pet according to an embodiment of the present disclosure.

[0100] As shown in Figure 5 The mechanical pet 520 comprises the circuit according to any one of the above, and the charging base 510 comprises:

[0101] a battery replacement structure for receiving the first main battery ejected by the mechanical pet 520 and placing a fully charged second main battery into the mechanical pet 520;

[0102] a charging structure for charging the first main battery.

[0103] In some embodiments, the mechanical pet 520 can be moved to dock the part where the main battery 110 is located with the battery replacement structure of the charging base 510.

[0104] For example, the main battery can be arranged at the back of the mechanical pet, and the mechanical pet can be moved to tightly contact a wall of the charging base on one side, and the wall has the battery replacement structure arranged on the inner side.

[0105] When the mechanical pet receives the pop-out instruction, the control module in the mechanical pet can close the first switch to switch to power supply by the backup battery, disconnect the first main battery from the mechanical pet, and then pop out the first main battery. After the first main battery is popped out, the battery replacement structure interfacing with the mechanical pet can receive the first main battery and put the second main battery full of electricity into the mechanical pet. The mechanical pet receives the second main battery, the second main battery is connected to the mechanical pet, and the control module can disconnect the first switch to disconnect the backup battery power supply and switch to the second main battery power supply for the mechanical pet. The pop-out instruction can be triggered based on a pre-set trigger condition, can be sent to the mechanical pet by the charging base, or can be triggered by the user.

[0106] Based on the backup battery, the first switch and the control module in the mechanical pet, the mechanical pet can remain in an electrical state before, during and after battery replacement, without power failure.

[0107] After the second main battery is replaced, the mechanical pet can disconnect the interface with the charging base and continue to move, such as continuing the work temporarily interrupted due to the need to replace the battery.

[0108] In some embodiments, the charging base comprises a charging structure for charging the first main battery.

[0109] The charging structure is used to charge the replaced first main battery, and after the first main battery is fully charged, the next battery replacement of the mechanical pet is waited.

[0110] In some embodiments, the charging base can include two battery boxes.

[0111] Both battery boxes can charge the main battery placed in the battery box. The first battery box is an empty battery box for receiving the first main battery popped out by the mechanical pet. When the mechanical pet interfaces with the charging base, it is actually that the battery box in the mechanical pet interfaces with the first charging box. The second battery box contains a fully charged battery. The charging base further comprises a power structure for exchanging the first battery box with the second battery box when the first battery box receives the battery, and placing the fully charged battery in the second battery box into the battery box in the mechanical pet when the second battery box is in the position of the first battery box and interfaces with the mechanical pet.

[0112] In some embodiments, when the charging module of the mechanical pet comprises a wired charging module, the charging base further comprises a power supply end 530 of the wired charging module; when the charging module of the mechanical pet comprises a wireless charging module, the charging base further comprises a wireless charging coil 540 for charging the wireless charging module; when the charging module of the mechanical pet comprises a radio frequency charging module, the charging base further comprises a transmitting antenna 550 for transmitting radio frequency signals in the direction of the location of the mechanical pet.
