[0048] Example 1

[0049] At present, wireless charging technology is generally based on a set power and cannot be adjusted based on the size of the load of the device being charged. In current smart home devices, the same device usually has different loads. If a set high power is used for charging under a small load, the charged device can be easily damaged. If a set low power is used for charging under a large load, the charging efficiency of the charged device will be relatively low.

[0050] Based on the problems existing in the prior art, this embodiment provides a wireless charging management system, through which the transmission power of the transmitting circuit can be freely adjusted to adapt to the charging requirements of different loads of the receiving module, and effectively improve the charging efficiency of the charged device. Figure 1 As shown in , the wireless charging management system of this embodiment includes a transmitting module and a receiving module; wherein:

[0051] In this embodiment, the transmitting module includes a first control unit, a power management unit, a transmitting circuit and a first temperature detection unit.

[0052] In this embodiment, the power management unit is connected to the power supply and the transmitting circuit, and is used to receive the electrical signal output by the power supply, and after processing the input electrical signal, output it to the transmitting circuit to perform electromagnetic wave transmission. In this embodiment, the power management unit can use power management chips such as APW8710A and APW8713, including functions such as voltage regulation, current regulation, frequency regulation, PWM / PFM mode regulation, rectification and filtering. This embodiment does not limit the specific structure or circuit of the power management unit, but it is required to be able to meet the functions of detecting and adjusting the transmission power of the transmitting coil. In this embodiment, the transmitting circuit mainly includes an oscillation source module, a power amplifier module and a transmitting coil, wherein the oscillation source module is connected to the transmitting coil through the power amplifier module.

[0053] In this embodiment, the first control unit is connected to the power management unit, and is used to detect and adjust the transmission power of the transmission circuit through the power management unit; in this embodiment, the first control unit can detect the transmission power of the transmission circuit in real time through the power management unit. Specifically, the first control unit can detect the transmission power of the transmission circuit by collecting voltage and current information in the power management unit. When the first control unit determines that the transmission circuit needs to be power adjusted, a power adjustment signal can be generated according to the current transmission power of the transmission circuit and sent to the power management chip, so that the power management chip can adjust the power of the transmission circuit according to the power adjustment signal. In this embodiment, the first control unit can use a control chip such as a single-chip microcomputer.

[0054] In this embodiment, the first control unit can be connected to an external terminal through a first wireless communication unit. The external terminal includes a mobile phone, a computer, and a handheld device. After the external terminal establishes a communication connection with the first control unit, it can send a power adjustment instruction to the first control unit. The first control unit generates a power adjustment signal based on the power adjustment instruction, thereby realizing the adjustment of the transmission power of the transmitting circuit.

[0055] In this embodiment, the first controller, such as a single-chip microcomputer, can be connected to an external trigger unit through an IO port. The trigger unit can be an input device, such as a button or an interactive display screen, etc. When it is a button, one or more can be set, for example, including two buttons A and B, wherein the trigger signal of the A button indicates that the transmission power of the transmitting circuit increases by a, and the trigger signal of the B button indicates that the transmission power of the transmitting circuit decreases by b. Based on this, after each press of the A button, the current transmission power of the transmitting circuit can be increased by a, and after each press of the B button, the current transmission power of the transmitting circuit can be reduced by b; for another example, including four buttons A, B, C, and D, wherein the trigger signals of the four buttons A, B, C, and D respectively indicate that the transmission power of the transmitting circuit is adjusted to a, b, c, and d, then when the A, B, C, and D buttons are pressed respectively, the current transmission power of the transmitting circuit can be adjusted to a, b, c, and d accordingly. Of course, the setting of the buttons is not limited to the above, and can be specifically set according to the actual power adjustment requirements of the transmitting circuit.

[0056] In this embodiment, the receiving module includes a receiving circuit, a receiving conversion unit, a second temperature detection unit and a power detection unit, and the receiving circuit includes a receiving coil; the transmitting coil in the transmitting circuit and the receiving coil in the receiving circuit can be set to a relative and parallel position relationship. When the current in the transmitting circuit flows through the transmitting coil, a magnetic field is generated. At this time, when the receiving circuit that is not connected to the power supply is close to the magnetic field, a current is generated, that is, the electromagnetic wave signal generated by the transmitting coil is converted into an electrical signal, and the generated current is input into the receiving conversion unit. The receiving conversion unit connects the receiving circuit and the charging circuit, and is used to convert the electrical signal output by the receiving circuit, and output the converted signal to the charging circuit, so as to charge the charged device through the charging circuit. In this embodiment, the receiving conversion unit may include one or more of a boost / buck circuit, a rectifier circuit, an inverter circuit and a filter circuit, and is used to perform boost / buck, rectifier, filter, inversion and other conversion operations on the current generated by the receiving circuit, so that the output electrical signal meets the charging demand of the charged device; the circuit function included in the receiving conversion unit can be selected according to the actual charging demand, and this embodiment is not limited.

[0057] In this embodiment, the transmitting circuit is also connected to the first control unit, which is used to detect the response from the receiving circuit and feed back the response signal to the first control unit, and the first control unit determines the energy signal required by the receiving module according to the signal fed back by the transmitting circuit. Furthermore, in this embodiment, the power of the transmitting circuit can be adjusted in the following manner: the first control unit determines the load size of the receiving module according to the energy signal required by the receiving end, and generates a power adjustment signal according to the load size of the receiving module; wherein, in this embodiment, the transmitting circuit detects the response from the receiving circuit after transmitting the electromagnetic wave signal, and feeds back the response signal to the first control unit, and the first control unit determines the energy signal required by the receiving module according to the signal fed back by the transmitting circuit.

[0058] In this embodiment, the first temperature detection unit of the transmitting module is connected to the first control unit, and the first temperature detection unit detects the temperature information of the transmitting module and feeds it back to the first control unit. The first control unit determines whether the temperature exceeds the first temperature threshold based on the received temperature information. If so, the first control unit can control the transmitting circuit to stop working through the power management unit, that is, control the transmitting circuit to cut off the power, so that the transmitting circuit stops emitting electromagnetic wave signals, and the receiving module stops charging the charged device.

[0059] In this embodiment, the second temperature detection unit and the receiving conversion unit of the receiving module are both connected to the second control unit; the second control unit can be a controller set in the receiving module, or a main controller of the charged device, specifically a control chip such as a single-chip microcomputer. The second temperature detection unit detects the temperature information of the receiving module and feeds it back to the second control unit. The second control unit determines whether the temperature of the receiving module exceeds the second temperature threshold based on the received temperature information. If it exceeds, the second control unit controls the charged device to stop charging to avoid further overheating.

[0060] In this embodiment, the receiving conversion unit is connected to the second control unit through a relay; the control end of the relay is connected to the IO port of the second control unit, and the controlled end of the relay is connected to the circuit of the receiving conversion unit, the input end of the receiving conversion circuit or the output end of the receiving conversion circuit. The second control unit controls the receiving conversion unit through the relay whether to output the converted electrical signal to the charging circuit. When the controlled end of the relay is in the on state, the receiving conversion unit can output the converted electrical signal to the charging circuit (the receiving conversion unit is defined as being in the on state at this time), so the charged device can be charged; when the controlled end of the relay is in the off state, the receiving conversion unit cannot output the converted electrical signal to the charging circuit, so charging cannot be performed (the receiving conversion unit is defined as being in the off state at this time). Specifically, the input ends of the relay are the two ends of the coil, one end of which is connected to the IO port of the second control unit, and the other end is connected to the ground or the power supply; the controlled end of the relay includes at least one pair of contacts, each pair of contacts includes a static contact and at least two moving contacts (including a static contact x, a moving contact x1 and a moving contact x2). In this embodiment, the static contact x and one of the moving contacts x1 in a pair of contacts of the relay are connected to the circuit of the receiving conversion unit, the input end of the receiving conversion circuit or the output end of the receiving conversion circuit (defined as: the connected static contact x and the moving contact x1), respectively. Figures 2a to 2c As shown; the second control unit outputs a high level or low level signal to the control end of the relay, so that the static contact in each pair of contacts can only be connected to one of the moving contacts. When the connected static contact and the moving contact are connected, the receiving conversion unit circuit can output the converted electrical signal to the charging circuit.

[0061] In this embodiment, the first temperature detection unit and the second temperature detection unit may be temperature sensors, and the specific types are not limited.

[0062] In this embodiment, the power detection unit of the receiving module is connected to the second control unit, so that the second control unit detects the power information of the charged device through the power detection unit, and controls the working state of the receiving conversion unit according to the power information. Specifically, when the power is above the upper power threshold, the second control unit can control the receiving conversion unit to be in a disconnected state through a relay to stop charging the charged device. When the power is less than or equal to the lower power threshold, the second control unit can control the receiving conversion unit to be in a conducting state through a relay to start charging the charged device. Among them, the lower power threshold is less than the upper power threshold, the upper power threshold is usually the power value of the charging device when it is fully charged, and the lower power threshold is usually the power value that can ensure the basic operation of the charged device.

[0063] In this embodiment, the transmitting module includes a first circuit board; the first control unit, the power management unit and the first temperature detection unit are respectively arranged on the first circuit board, the first circuit board is provided with a first interface connected to the first control unit and the power management unit, the first circuit board is connected to the power supply and / or the computer through the first interface, in this embodiment, the transmitting module can be powered by the first interface, and the first interface can be used as a download interface, and the first control unit burns the program from the computer through the first interface; Figure 3 As shown in FIG. 1 , a first magnetic sheet 2 is arranged on the back of a transmitting coil 1 of the transmitting circuit, and a side of the first magnetic sheet 2 facing away from the transmitting coil 1 is mounted on a first circuit board 4 through a foam 3 .

When the second control unit is the controller in the receiving module, the second interface is connected to the charging circuit of the charged device, connected to the battery through the charging circuit, or the second interface is directly connected to the battery. When the second control unit is the main controller of the charged device, the second interface is used to connect to the battery and the main controller at the same time, so that the receiving conversion unit can be connected to the battery and the main controller through the second interface. A second magnetic sheet is arranged on the back of the receiving coil of the receiving circuit, and the side of the second magnetic sheet facing away from the receiving coil is mounted on the second circuit board through foam.

[0065] In this embodiment, both the transmitting coil and the receiving coil are formed by a multi-layer spiral structure wound by a conductive wire, and each layer of coils is located in the same plane, and the overall shape is an ellipse with a rectangular hollow in the middle.

[0067] This embodiment 2

[0068] This embodiment discloses a smart lock, including a main controller, a battery and the wireless charging management system described in Example 1; in the wireless charging management system, the receiving conversion unit of the receiving module is connected to the battery through a charging circuit to charge the battery.

[0069] In this embodiment, the second control unit involved in the wireless charging management system can be a control chip in the receiving module, such as a single-chip microcomputer, or it can be directly the main controller in the smart lock. If it is the former, the second control unit can be directly set on the second circuit board of the receiving module, and communicate with the main controller in the smart lock. The receiving module can be connected to the main controller of the smart lock and the battery through the second interface on the second circuit board. Specifically: based on the second interface, the second control unit is connected to the main controller, the receiving conversion unit is connected to the charging circuit of the battery, or the receiving conversion unit is connected to the battery through the charging circuit. If it is the latter, there is no need to arrange a control chip in the receiving module. The devices in the receiving module that need to be connected to the second control unit, including the receiving conversion unit, the relay, the second temperature detection unit, the power detection unit and other devices are connected to the second interface, and connected to the main controller through the second interface. At the same time, the receiving conversion unit is connected to the charging circuit of the battery through the second interface, or the receiving conversion unit is connected to the charging circuit and then connected to the battery through the second interface.

[0070] In this embodiment, the charging circuit of the smart lock battery can be set on the second circuit board, that is, it can be set as a circuit belonging to the receiving module, or it can be set at the battery charging input end. The specific setting can be set according to the overall layout requirements of the smart lock.

[0071] In this embodiment, the transmitting coil in the transmitting circuit of the transmitting module is installed on the door frame, and the receiving coil in the receiving circuit of the receiving module is set at the corresponding position of the door leaf; when the door leaf is closed, the transmitting coil and the receiving coil are relative and parallel. At this time, if the transmitting circuit senses that the receiving circuit and the receiving module have been connected to the load by transmitting a low-power signal, the power management chip controls the transmitting circuit to transmit electromagnetic waves with a certain transmitting power, and the electrical signal output by the receiving circuit passes through the receiving conversion unit and is output to the charging circuit of the battery to realize the charging of the smart lock battery. Based on this, under normal circumstances, when the door leaf is closed so that the transmitting coil and the receiving coil are parallel and relative, the charging of the battery can be started, and when the battery charging capacity reaches the upper limit threshold, the second control unit will control to stop charging; when the door leaf is open, since the transmitting circuit cannot sense the receiving circuit by transmitting a low-power signal, the transmitting circuit will not transmit a high-power electromagnetic signal. In addition, since the receiving coil is far away from the transmitting coil, it will not sense the magnetic field, so the charging of the battery is stopped.

[0072] In this embodiment, the smart lock can be charged in the following ways:

[0073] The first type: each time the door leaf is closed, the power detection unit detects the current power information of the battery. If the current power information of the battery is greater than the lower power threshold, the battery is controlled not to be charged. If the current power information of the battery is less than or equal to the lower power threshold, the battery is controlled to be charged until the charging power reaches the upper power threshold.

[0074] The second method: each time the door leaf is closed, the power detection unit detects the current power information of the battery. If the current power information of the battery is less than the upper power threshold, the battery is charged until the charged power returns to the upper power threshold.

[0075] In this embodiment, whether to charge can be determined based on the current power level of the battery; the specific charging method can be set according to actual needs.

[0076] In this embodiment, the main controller can also connect to the user terminal through a near-field first wireless communication unit such as Bluetooth, or connect to the cloud platform through a far-field second wireless communication unit such as wifi, and then connect to the user terminal through the cloud platform. Based on this, the user terminal can establish a connection with the main controller of the smart lock, and further control the receiving module through the main controller, thereby controlling the charging work; for example, the user can start the charging of the battery through the user terminal according to the actual charging demand. If the current battery power is between the upper power threshold and the lower power threshold, the battery is not charged according to the first charging method. At this time, the user can start charging through the user terminal. The specific user sends a charging start signal to the main controller through the user terminal. After the main controller receives the charging start signal, based on the relationship between the main controller and the second control unit (the main controller is the second control unit or the main controller is connected to the second control unit), the second control unit controls the relay working state, so that the receiving conversion module can output the converted electrical signal to the charging control circuit, thereby controlling the battery to charge.

[0077] Smart locks are different from traditional mechanical locks and are more intelligent in terms of user identification, security, and manageability. They are the executive components of door locking in access control systems. In addition to the above structure, the smart lock of this embodiment also includes the necessary circuits and structures of existing smart locks, such as front and rear panels, lock body, unlocking module (button, fingerprint, face recognition, etc.), etc., which will not be repeated here.

[0078] The above is only an optional implementation method for some implementation scenarios of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the technical concept of the solution of the present application, other similar implementation methods based on the technical ideas of the present application are also within the protection scope of the embodiments of the present application.
