[0003] In the related technical field, the controller in the charging device cannot communicate with some charging modules, so it cannot obtain the running state of some charging modules, which leads to the fact that the controller cannot allocate power to some charging modules, resulting in low charging efficiency of the charging device.

DETAILED DESCRIPTION
[0013] In order to make the purpose, technical solutions and advantages of the application more clear, the following will further describe the application in combination with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the application, and are not used to limit the application.
[0014] Please refer to Figure 1 This application provides a charging device 1, which includes a housing 11, a main control board, a dedicated wireless charging module 12, and a universal wireless charging module 13.
[0015] The housing 11 is used to install and house the main control board, the dedicated wireless charging module 12, the universal wireless charging module 13, and the control module 2. This housing 11 protects the main control board, dedicated wireless charging module 12, universal wireless charging module 13, and control module 2, reducing the probability of damage to these components and thus extending the lifespan of the charging device 1. For example, the housing 11 can be made of plastic to reduce its weight, thereby reducing the overall weight of the charging device 1 and facilitating its use and portability. It is understood that the housing 11 can be integrally molded using injection molding to achieve high structural strength, further reducing the probability of damage to the housing 11 and consequently, the probability of damage to the charging device 1.
[0016] The dedicated wireless charging module 12 may include a control chip 121, a transformer 122, and a first wireless charging coil 123. The control chip 121 is connected to the transformer 122 and the first wireless charging coil 123. The control chip 121 controls the output power of the transformer 122 and can send a detection signal to the first wireless charging coil 123 to detect the operating status of the first wireless charging coil 123. For example, the dedicated wireless charging module 12 includes at least one of the following: an Apple Watch wireless fast charging module and a Huawei Watch wireless fast charging module. In other embodiments, the dedicated wireless charging module 12 can also provide wireless charging for a first external device, which includes at least one of an Apple Watch, a Huawei Watch, and an Android Watch.
[0017] The universal wireless charging module 13 can charge at least one of a mobile device and headphones. In this embodiment, the specific form of the universal wireless charging module 13 is not limited. Exemplarily, when the universal wireless charging module 13 includes a second wireless charging coil, the second wireless charging coil can charge the mobile device alone, including mobile phones and tablets. In other embodiments, the second wireless charging coil can also charge the headphones alone. It is understood that when the universal wireless charging module 13 includes at least two second wireless charging coils, the universal wireless charging module 13 can charge both the mobile device and headphones simultaneously through the second wireless charging coils.
[0018] Please refer to Figure 1Through the above technical solution, the charging device 1 can charge at least two external devices simultaneously. However, since the dedicated wireless charging module 12 is a dedicated wireless charging module, such as the Apple Watch wireless fast charging module, and the Apple Watch wireless fast charging module does not open its data interface to third-party manufacturers, the controller 22 in the charging device 1 cannot communicate with the control chip 121 of the dedicated wireless charging module 12. As a result, the controller 22 cannot obtain the operating status information of the dedicated wireless charging module 12. Therefore, when the charging device 1 is running, the first power of the dedicated wireless charging module 12 needs to be reserved to power the transformer 122 at all times to ensure that when the first external device is connected to the dedicated wireless charging module 12, the dedicated wireless charging module 12 can charge the first external device with its own first rated power.
[0019] However, when the output power of the adapter of the charging device 1 is low, the dedicated wireless charging module 12 can charge the first external device at the first rated power, but cannot charge the second external device at the second rated power of the general wireless charging module 13. If the first power is always reserved to power the transformer 122 of the dedicated wireless charging module 12, the general wireless charging module 13 will not be able to charge the second external device at the second rated power, resulting in low charging efficiency of the general wireless charging module 13 for the second external device, and thus low overall charging efficiency of the charging device 1.
[0020] Based on the above, please refer to Figure 1 and Figure 2 In one embodiment, the charging device 1 further includes a control module 2, which is disposed inside the housing 11. The control module 2 includes a detection circuit 21 and a controller 22. The detection circuit 21 is used to detect the operating status of the dedicated wireless charging module 12. The controller 22 is connected to the output terminal of the detection circuit 21 and is connected to both the dedicated wireless charging module 12 and the general wireless charging module 13.
[0021] It is understood that the controller 22 can be mounted on and connected to the main control board. In other embodiments, the controller 22 can also be mounted outside the main control board. In the embodiments of this application, no specific restrictions are placed on the relationship between the controller 22 and the main control board.
[0022] In this embodiment, the controller 22 can obtain the working status of the dedicated wireless charging module 12 through the detection circuit 21. Therefore, when the output power of the adapter of the charging device 1 is low, there is no need to reserve the first power to supply power to the transformer 122 of the dedicated wireless charging module 12. This enables power distribution between the dedicated wireless charging module 12 and the general wireless charging module 22, thereby improving the charging efficiency of the general wireless charging module 13 for charging the second external device and improving the overall charging efficiency of the charging device 1.
[0023] Specifically, when the dedicated wireless charging module 12 is in an unloaded state, the control chip 121 sends a detection signal to the first wireless charging coil 123 to detect the operating status of the first wireless charging coil 123. At this time, the controller 22 can collect the first acquisition signal corresponding to the detection signal through the detection circuit 21, so that the controller 22 can obtain the status information of the dedicated wireless charging module 12 being in an unloaded state through the first acquisition signal.
[0024] When the control chip 121 detects that the first wireless charging coil 123 is coupled to the first external device through the detection signal, the control chip 121 sends a charging signal to the first wireless charging coil 123. At this time, the controller 22 can collect a second acquisition signal corresponding to the charging signal through the detection circuit 21. This allows the controller 22 to obtain the status information of the dedicated wireless charging module 12 being in a loaded state through the second acquisition signal. This enables the controller 22 to control the power supply (not shown in the figure) to supply power to the transformer 122 of the dedicated wireless charging module 12 at a first power, thereby enabling the first wireless charging coil 123 to charge the first external device at a first rated power. It can be understood that the detection signal sent by the control chip 121 through the first wireless charging coil 123 can be a first handshake signal. After the first external device receives the first handshake signal, it can send a second handshake signal to the control chip 121, so that the control chip 121 can obtain information such as the charging power, charging current, charging voltage, and remaining power of the first external device, thereby facilitating the first wireless charging coil 123 to charge the first external device.
[0025] When the first wireless charging coil 123 is coupled to the first external device, if the universal wireless charging module 13 is connected to the second external device, the controller 22 can control the universal wireless charging module 13 to charge the second external device with an output power less than its own second rated power, thereby ensuring that the charging device 1 can charge both the first and second external devices at the same time.
[0026] When the controller 22 detects through the detection circuit 21 that the dedicated wireless charging module 12 is in an unloaded state, the controller 22 can control the power supply to supply power to the dedicated wireless charging module 12 at a power lower than the first power, so as to meet the requirement of the dedicated wireless charging module 12 to emit a detection signal, thereby enabling the general wireless charging module 13 to charge the second external device at its own second rated power, thereby improving the charging efficiency of charging the second external device.
[0027] When the universal wireless charging module 13 charges the second external device with its second rated power, if the controller 22 detects through the detection circuit 21 that the dedicated wireless charging module 12 is connected to the first external device, the controller 22 can control the output power of the universal wireless charging module 13 to decrease, and control the dedicated wireless charging module 12 to charge the first external device with its first rated power, thereby improving the energy utilization rate and improving the overall charging efficiency of the charging device 1.
[0028] It is understandable that when the dedicated wireless charging module 12 is not connected to the first external device, the control chip 121 can send an abnormal signal to the first wireless charging coil 123. The controller 22 can collect the third acquisition signal corresponding to the abnormal signal through the detection circuit 21, so that the controller 22 can obtain the information that the dedicated wireless charging module 12 is not connected to the first external device.
[0029] Understandably, after the first external device is fully charged, the control chip 121 can send a full-charge signal to the first wireless charging coil 123. The controller 22 can obtain the fourth acquisition signal corresponding to the full-charge signal through the detection circuit 21, so that the controller 22 can obtain the full-charge information of the first external device. At this time, the controller 22 can control the power supply to supply power to the transformer 122 of the dedicated wireless charging module 12 at a power lower than the first power, and control the power supply to supply power to the general wireless charging module 13 at the second power, thereby increasing the charging power of the general wireless charging module 13, thereby increasing the charging efficiency of the general wireless charging module 13 for charging the second external device, and thus improving the overall charging efficiency of the charging device 1. In other embodiments, the controller 22 can also control the power supply to maintain the first power to supply power to the transformer 122 of the dedicated wireless charging module 12, so as to ensure that the first external device is fully charged when the user takes it, thus facilitating user use.
[0030] It is understood that the charging device 1 may also include multiple universal wireless charging modules 13. When the controller 22 controls the power supply to supply power to the transformer 122 of the dedicated wireless charging module 12 at a power lower than the first power, the power distribution among the multiple universal wireless charging modules 13 can be determined based on at least one of the following factors: the remaining power of the multiple second external devices, their rated power, and a preset priority. In this embodiment, the power distribution method among the multiple second external devices is not limited.
[0031] In this embodiment of the application, no specific restrictions are placed on the type and form of the acquisition signals obtained by the controller 22 through the detection circuit 21.
[0032] Please refer to Figure 1 and Figure 2In one embodiment, the detection circuit 21 includes a data acquisition circuit 211, a rectifier circuit 212, a filter circuit 213, and a voltage regulator circuit 214.
[0033] The acquisition circuit 211 is connected to the dedicated wireless charging module 12, and the controller 22 can obtain the operating status of the dedicated wireless charging module 12 through the acquisition circuit 211. The input terminal of the rectifier circuit 212 is connected to the output terminal of the acquisition circuit 211; the input terminal of the filter circuit 213 is connected to the output terminal of the rectifier circuit 212; the input terminal of the voltage regulator circuit 214 is connected to the output terminal of the filter circuit 213, and the output terminal of the voltage regulator circuit 214 is the output terminal of the detection circuit 21.
[0034] Specifically, the controller 22 can acquire the signal sent by the control chip 121 to the first wireless charging coil 123 through the acquisition circuit 211, which can correspond to the operating status of the dedicated wireless charging module 12.
[0035] It is understood that the acquisition circuit 211 can acquire the signal sent by the control chip 121 to the first wireless charging coil 123 through electromagnetic induction. In other embodiments, the acquisition circuit 211 also acquires the signal by other means. In the embodiments of this application, the specific form of the acquisition circuit 211 is not limited.
[0036] The rectifier circuit 212 is used to rectify the signal acquired by the acquisition circuit 211. It is understood that since the acquisition circuit 211 can have different acquisition methods, resulting in different output signals, the rectifier circuit 212 can include at least one of a full-wave rectifier circuit, a half-wave rectifier circuit, and a bridge rectifier circuit to match the output signal waveform of the acquisition circuit 211 and the signal waveform required by the controller 22. In this embodiment, the specific form of the rectifier circuit 212 is not limited.
[0037] For example, rectifier circuit 212 may include a full-wave rectifier circuit, which converts an alternating current signal into a unidirectional signal. The full-wave rectifier circuit may be composed of at least two rectifiers combined, one responsible for forward rectification and the other for reverse rectification. Specifically, the full-wave rectifier circuit may be a rectifier bridge composed of four diodes. It is understood that the full-wave rectifier circuit may also be composed of four MOSFETs.
[0038] The rectifier circuit 212 may also include a half-wave rectifier circuit, which may include a diode. The diode is used to perform rectification, so as to use the diode to remove half of the cycle and leave the remaining half of the cycle as a rectifier circuit.
[0039] The rectifier circuit 212 may also include a bridge rectifier circuit, which consists of four diodes connected in a "bridge" structure, and can convert the AC power output from the AC transformer circuit into unidirectional pulsating DC power.
[0040] It is understood that, in other embodiments, the rectifier circuit 212 may simultaneously include a full-wave rectifier circuit and a half-wave rectifier circuit. In other embodiments, the rectifier circuit 212 may simultaneously include a full-wave rectifier circuit and a bridge rectifier circuit. In other embodiments, the rectifier circuit 212 may simultaneously include a half-wave rectifier circuit and a bridge rectifier circuit. In other embodiments, the rectifier circuit 212 may include a full-wave rectifier circuit, a half-wave rectifier circuit, and a bridge rectifier circuit.
[0041] The filter circuit 213 is used to filter the output signal of the rectifier circuit 212, thereby reducing the probability of noise signals entering the controller 22 and improving the accuracy of the controller 22 in obtaining the operating status of the dedicated wireless charging module 12 through the detection circuit 21. It is understood that the filter circuit 213 can be a high-frequency filter circuit 213. In other embodiments, it can also be a low-frequency filter circuit 213. In this application embodiment, the specific form of the filter circuit 213 is not limited.
[0042] The voltage regulator circuit 214 stabilizes the voltage of the signal at the output of the filter circuit 213 to a preset value, thereby reducing the probability that the voltage exceeds the withstand voltage of the controller 22, which in turn reduces the probability of damage to the controller 22 and allows the controller 22 to have a longer service life, which in turn allows the control module 2 to have a longer service life.
[0043] Please refer to Figures 1-3 In one embodiment, the acquisition circuit 211 may include a current transformer Q1, which is coupled to the dedicated wireless charging module 12. The output terminal of the current transformer Q1 is the output terminal of the acquisition circuit 211. Specifically, there is a connection line between the control chip 121 and the first wireless charging coil 123. The current transformer Q1 is coupled to the connection line. When the control chip 121 sends a signal to the first wireless charging coil 123, a corresponding acquisition signal can be sensed on the current transformer Q1 through the principle of electromagnetic induction. The controller 22 obtains the operating status of the dedicated wireless charging module 12 through the corresponding acquisition signal.
[0044] Please refer to Figures 1-3Furthermore, the current transformer Q1 has a first output terminal Q1A and a second output terminal Q1B. The rectifier circuit 212 has a first input terminal 212A, a second input terminal 212B, a positive terminal 212C, and a negative terminal 212D. The first input terminal 212A is connected to the first output terminal Q1A, the second input terminal 212B is connected to the second output terminal Q1B, the positive terminal 212C is the output terminal of the rectifier circuit 212, and the negative terminal 212D is grounded. The rectifier filter circuit 213 includes a first diode D1, a second diode D2, a third diode D3, and a fourth diode D4. Diode D4 has the following configuration: the anode of the first diode D1 is connected to the first input terminal 212A, and the cathode of the first diode is connected to the positive terminal 212C of the rectifier circuit 212; the anode and cathode of the second diode D2 are connected to 212D, and the cathode of the second diode D2 is connected to the anode of the first diode D1; the anode of the third diode D3 is connected to the second input terminal 212B, and the cathode of the third diode is connected to the cathode of the first diode; the anode of the fourth diode D4 is connected to the anode of the second diode D2, and the cathode of the fourth diode D4 is connected to the anode of the third diode D3.
[0045] A full-wave rectifier bridge is formed by first diode D1, second diode D2, third diode D3 and fourth diode D4 to rectify the sinusoidal acquisition signal induced by current transformer Q1 to output a DC pulse signal, so that the controller 22 can obtain the operating status of the dedicated wireless charging module 12 through the DC pulse signal.
[0046] Please refer to Figures 1-3 In one embodiment, the filter circuit 213 may include a first capacitor C1. The first plate of the first capacitor C1 is the input terminal of the filter circuit 213, the first plate of the first capacitor C1 is the output terminal of the filter circuit 213, and the second plate of the first capacitor C1 is grounded. The first capacitor C1 is used to filter out noise signals in the sinusoidal acquisition signal output by the current transformer Q1, thereby improving the accuracy of the acquisition signal obtained by the controller 22, and thus improving the accuracy of the operating status of the dedicated wireless charging module 12 obtained by the controller 22.
[0047] It is understood that the filter circuit 213 may include multiple first capacitors C1, the first plate of each first capacitor C1 is connected to the input terminal of the filter circuit 213, the second plate of each first capacitor C1 is grounded, and the capacitance values of the multiple first capacitors C1 may be the same or different. In the embodiments of this application, there are no specific limitations on the number or capacitance value of the first capacitors C1.
[0048] For example, the filter circuit 213 may include two first capacitors C1, one of which has a larger capacitance than the other. By connecting the first capacitors C1 with different capacitance values in parallel, the filtering problem of signals at different frequencies can be better solved. The first capacitor C1 with a larger capacitance value can store more electrical energy and effectively filter out low-frequency signals; while the first capacitor C1 with a smaller capacitance value has a lower self-resonant frequency and can effectively filter out high-frequency signals. Therefore, the design of using two capacitors of different capacitance values in parallel can better solve the filtering problem of signals at different frequencies and improve the filtering effect of the filter circuit 213.
[0049] Please refer to Figures 1-3 In one embodiment, the voltage regulator circuit 214 includes a first resistor R1 and a second capacitor C2. The first end of the first resistor R1 is the input end of the voltage regulator circuit 214. The first plate of the second capacitor C2 is connected to the second end of the first resistor R1. The first plate of the second capacitor C2 is the output end of the voltage regulator circuit 214. The second plate of the second capacitor C2 is grounded.
[0050] The first resistor R1 is used to divide and limit the current of the acquisition signal output from the filter circuit 213 to prevent large currents and voltages from directly entering the controller 22. This reduces the probability of damage to the controller 22, thus extending its service life and consequently the charging device 1. The second capacitor C2 stabilizes the acquisition signal entering the controller 22, improving the accuracy of the controller 22 in determining the operating status of the dedicated wireless charging module 12 based on the acquisition signal.
[0051] Please refer to Figures 1-3 In one embodiment, the voltage regulator circuit 214 further includes a second resistor R2. The first end of the second resistor R2 is connected to the first plate of the second capacitor C2, and the second end of the second resistor R2 is connected to the second plate of the second capacitor C2. When the voltage applied between the two plates of the second capacitor C2 is large, the second capacitor C2 can discharge through the second resistor R2 to prevent damage to the second capacitor C2, thereby extending the service life of the second capacitor C2 and consequently extending the service life of the charging device 1.
