Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, exemplary embodiments according to the present invention will be described in detail with reference to the accompanying drawings. It should be apparent that the described embodiments are only some embodiments of the present invention and not all embodiments of the present invention, and it should be understood that the present invention is not limited by the example embodiments described herein. Based on the embodiments of the invention described in the present application, all other embodiments that a person skilled in the art would have without inventive effort shall fall within the scope of the invention.
Example 1
The present invention provides a charging device to solve the above technical problems, and the charging device is described in detail below with reference to the accompanying drawings.
First, referring to fig. 2, fig. 2 shows a schematic block diagram of a charging device 200 according to an embodiment of the present invention.
As shown in fig. 2, the charging device 200 according to the embodiment of the present invention includes a switching circuit 210, a boosting circuit 220, and a current detecting circuit 230 provided in the charging device.
According to the embodiment of the invention, the charging device can be used for charging various electronic products, such as but not limited to a smart phone, a notebook computer, an interphone, a Bluetooth headset, a Bluetooth sound box, an outdoor monitor and the like. In the following embodiments, a bluetooth headset is taken as an example, but it should be noted that the detection device for detecting other electronic products is similar or identical.
Wherein, the on and off of the charging device is realized by the opening and closing of the switching circuit.
Optionally, the switch circuit is a hall switch circuit, and the charging device is triggered by the hall switch. For example, when the charging device is a headset charging box, the charging box 5V voltage boosting circuit is opened through the Hall switch circuit to charge the headset.
Wherein the boost circuit 220 is configured to boost the voltage of the charging device to the charging voltage and maintain the charging voltage for a first predetermined period after the switch circuit is turned on.
Of course, the booster circuit 220 is further configured to reduce the voltage of the charging device below the charging voltage when no charging operation occurs within the first predetermined period or no recharging operation occurs within the second predetermined period after the charging is completed, so that the charging device is in a low power consumption operation state.
The current detection circuit 230 is configured to detect a magnitude of a current in the charging device, and if the detected current is a charging current in a first predetermined period, the voltage of the charging device is maintained as a charging voltage and charging is performed; if the detected current is always smaller than the charging current in the first preset period, the voltage of the charging device is reduced to be lower than the charging voltage, so that the charging device is in a low-power-consumption working state.
The current detected at the current detection circuit 230 being smaller than the charging current may include the following two states:
firstly, an interface of an electronic product to be charged is electrically connected with a contact of a charging device, and the electronic product to be charged is charged, at the moment, the current in the charging device is smaller than the normal charging current;
second, although the switching circuit has opened the charging device and the charging device has increased the voltage to the charging voltage, the interface of the electronic product to be charged is not electrically connected to the contacts of the charging device (i.e. the electronic product to be charged is not charged), and the current in the charging device is also smaller than the normal charging current.
When the two conditions are generated, the charging voltage is kept for a second preset period for the first condition, the charging voltage is kept for a first preset period for the second condition, the voltage of the charging device is kept at the charging voltage by the voltage boosting circuit, the detected current in the respective preset periods is still smaller than the charging current, the voltage boosting circuit is closed, but the charging device is not closed and can work in a low-voltage state and is in a low-power-consumption working state.
Example two
As shown in fig. 2, the charging device 200 according to the embodiment of the present invention includes a switching circuit 210, a boosting circuit 220, and a current detecting circuit 230 provided in the charging device.
The selection and setting manners of the switch circuit 210, the boost circuit 220 and the current detection circuit 230 can refer to the first embodiment, and of course, the manner in the first embodiment can be further modified, which is not described herein.
Unlike the first embodiment, the charging device further includes a micro program control unit; the microprogrammed control unit receives the detection signal of the current detection circuit 230, and controls the charging device to be in a charging state or a low-power-consumption working state. For example, if the detected current is equal to the normal charging current, the charging device is in a normal charging state, and the microprogrammed control unit controls the voltage of the charging device to be maintained at the charging voltage until the charging of the electronic product to be charged is completed and maintained for a second predetermined period.
If the detected current is smaller than the normal charging current, the charging device is in a non-charging state, and the micro-program control unit controls the charging device to enter a low-power-consumption working state.
Optionally, the detected current is smaller than the normal charging current, and the current change of the charging device can be further detected:
if the current is always in a state smaller than the normal charging current after the charging device is started, the interface of the electronic product to be charged is judged not to be electrically connected with the contact of the charging device (namely, the electronic product to be charged is not charged), in the state, the microprogrammed control unit controls the voltage of the charging device to be maintained at the charging voltage for a first preset period, and if the current detected in the first preset period is still smaller than the charging current, the voltage of the charging device is controlled to be reduced, so that the charging device is in a low-power-consumption working state.
If the current detection circuit detects a change of current after the charging device is started, for example, the current is reduced from a normal charging current to below the charging current, and the charging device is in a charging state before, the charging device is judged to be charged, the micro-program control unit controls the voltage of the charging device to be maintained at the charging voltage for a second preset period, and if the current detected in the second preset period is still smaller than the charging current, the voltage of the charging device is controlled to be reduced, so that the charging device is in a low-power-consumption working state.
As an alternative embodiment, the voltage reduction of the charging device is directly controlled when it is detected that the charging has been completed, and the second predetermined period is no longer maintained, so that the charging device is in a low power consumption operation state.
Alternatively, the time periods of the first predetermined period and the second predetermined period may be the same or different, and may be set according to actual needs.
Optionally, the microprogrammed control unit controls the voltage of the boost circuit to rise to the charging voltage so as to enable the charging device to be in a charging state;
or the microprogrammed control unit controls the voltage reduction of the booster circuit so as to enable the charging device to be in a low-power-consumption working state.
Wherein, the microprogrammed control unit adjusts the voltage by controlling the boost circuit.
The current detection circuit detects the magnitude of the current in the charging device, and if the detected current is the charging current in the first predetermined period, the micro-program control unit controls the voltage of the boost circuit to be kept at the charging voltage; if the current detected in the first preset period is always smaller than the charging current, the micro-program control unit controls the boost circuit to be closed so that the charging device is in a low-power-consumption working state;
or after the charging is finished, if the current detected by the current detection circuit in the second preset period is always smaller than the charging current, the micro-program control unit controls the voltage of the voltage boosting circuit to be reduced below the charging voltage so that the charging device is in a low-power-consumption working state.
Optionally, the charging device further includes: and the interface unit is used for electrically connecting the electronic product to be charged with the charging device so as to charge the electronic product to be charged.

the charging device is a charging box of the TWS earphone, and a 5V booster circuit of the charging box is opened to charge the earphone in a mode of triggering through a Hall switch.
In this embodiment, the Hall effect of the Hall switch is utilized to input high/low level to the microprogrammed control unit (Micro-programmed Control Unit, MCU) to allow the MCU to control the boost integrated circuit (Integrated Circuit, IC) to complete the boost process, thereby charging the earphone. When the earphone is charged in the charging box, the charging box booster circuit is controlled by detecting the charging current of the earphone through the current detection circuit, so that the charging box is in an ultralow-power-consumption working state.
Optionally, when the cover of the charging box is opened, a hall switch on the circuit is triggered to output a low level to the MCU, the MCU provides an enable signal to boost the DC/DC voltage by 5V and keep the 5V voltage for 3 minutes, and after the earphone is put into the charging box within 3 minutes, the earphone starts to be charged; if no earphone is put in within 3 minutes, the boosting IC is closed, and the charging box enters a low power consumption state. At this time, if the earphone needs to be charged, the cover only needs to be opened and closed again.
When the earphone is fully charged in the charging box, the charging current detection circuit detects that the earphone is charged in a cut-off mode, the charging box boosting circuit is closed, and the charging box enters a low-power-consumption working state.
Wherein, in this embodiment, the TWS headset may be a Bluetooth headset, the Bluetooth headset including a left Bluetooth headset and a right Bluetooth headset.
The earphone charging box comprises a box body, an intermediate member, a wire joint, a wire winding clamping piece, a circuit board, a battery, a box cover and the like.
The box cover and the box body can be closed to form a closed accommodating space for storing the earphone without using the earphone.
The box cover is provided with a connecting end, the box body is provided with a connecting seat, and the connecting end on the box body is connected with the connecting seat to fix the box cover. The charging box is opened by rotating the box cover, and the Hall switch circuit is triggered at the same time.
The earphone comprises a box body, a charging interface, an earphone body and a charging structure, wherein the box body is provided with the charging interface, and interface contacts matched with the charging structure are arranged on the earphone body so as to charge the earphone when the interface contacts on the earphone are connected with the charging interface.
The charging interface on the charging box can be an USB Type-C interface, a Micro-USB interface or a common convex contact.
As an implementation mode, a base is further arranged in the charging box, a convex contact is arranged on the base, and the earphone can be contacted with the charging box by placing the earphone into the base, so that the earphone is directly charged.
The charging device is arranged in the charging box, and other conventional structures of the charging box can be selected according to requirements, so that the charging device is not described herein.
According to the charging device, the charging control method, the charging control system and the storage medium, when the charging device is used for charging, the current in the charging device is detected through the current detection circuit, and if the detected current is the charging current in the first preset period, the voltage of the charging device is kept to be the charging voltage and the charging is carried out; if the detected current is always smaller than the charging current in the first preset period, the voltage of the charging device is reduced to be lower than the charging voltage, so that the charging device is in a low-power-consumption working state. The charging apparatus and method can maintain a stable state of charge while reducing power consumption in a non-charged state.
Example III
The present invention also provides a charge control method, first, a charge control method 100 for implementing an embodiment of the present invention is described with reference to fig. 1, as shown in fig. 1, including:
step S110: the switch circuit receives an instruction to control the opening and closing of the charging device;
step S120: the boost circuit receives an instruction to boost the voltage of the charging device to a charging voltage and hold the charging voltage for a first predetermined period after the switch circuit is turned on;
step S130: the current detection circuit receives an instruction to detect the magnitude of the current in the charging device, and if the detected current is the charging current in a first preset period, the voltage of the charging device is kept to be the charging voltage and charging is carried out; if the detected current is always smaller than the charging current in the first preset period, the voltage of the charging device is reduced to be lower than the charging voltage, so that the charging device is in a low-power-consumption working state.
In step S110, the charging device is turned on and off by opening and closing the switching circuit.
Specifically, the switch circuit is a hall switch circuit, and the charging device is triggered by the hall switch. For example, when the charging device is a headset charging box, the charging box 5V voltage boosting circuit is opened through the Hall switch circuit to charge the headset.
In step S120, the step-up circuit steps up the voltage of the charging device to the charging voltage and holds the same for a first predetermined period after the switching circuit is turned on.
The range of the first predetermined period is not limited to a certain range of values, and may be selected according to actual needs.
In step S130, the current detection circuit receives an instruction to detect the magnitude of the current in the charging device, wherein if the detected current is smaller than the normal charging current, the current change of the charging device may be further detected:
if the current is always in a state smaller than the normal charging current after the charging device is started, the interface of the electronic product to be charged is judged not to be electrically connected with the contact of the charging device (namely, the electronic product to be charged is not charged), in the state, the charging voltage is maintained for a first preset period, and if the current detected in the first preset period is still smaller than the charging current, the voltage of the charging device is reduced, so that the charging device is in a low-power-consumption working state.
If a change in current is detected after the charging device is started, for example, the current is reduced from a normal charging current to a charging current or below, and the charging device is in a charging state before, it is determined that charging of the electronic product to be charged is completed, the voltage boosting circuit maintains the voltage of the charging device at the charging voltage for a second predetermined period, and the detected current is still smaller than the charging current in the second predetermined period, the voltage boosting circuit is turned off, but the charging device is not turned off and is operated in a low-voltage state and is in a low-power consumption operating state. Or, as an alternative embodiment, the voltage of the charging device is directly controlled to be reduced when it is detected that the charging has been completed, and the charging device is not maintained for a second predetermined period, so that the charging device is in a low power consumption operation state.
The method is further described below in connection with an example in which the headset is charged by the headset charging cartridge.
The charging device is a charging box of the TWS earphone, and a 5V booster circuit of the charging box is opened to charge the earphone in a mode of triggering through a Hall switch.
In this embodiment, the Hall effect of the Hall switch is utilized to input high/low level to the microprogrammed control unit (Micro-programmed Control Unit, MCU) to allow the MCU to control the boost integrated circuit (Integrated Circuit, IC) to complete the boost process, thereby charging the earphone. When the earphone is charged in the charging box, the charging box booster circuit is controlled by detecting the charging current of the earphone through the current detection circuit, so that the charging box is in an ultralow-power-consumption working state.
Optionally, when the cover of the charging box is opened, a hall switch on the circuit is triggered to output a low level to the MCU, the MCU provides an enable signal to boost the DC/DC voltage by 5V and keep the 5V voltage for 3 minutes, and after the earphone is put into the charging box within 3 minutes, the earphone starts to be charged; if no earphone is put in within 3 minutes, the boosting IC is closed, and the charging box enters a low power consumption state. At this time, if the earphone needs to be charged, the cover only needs to be opened and closed again.
When the earphone is fully charged in the charging box, the charging current detection circuit detects that the earphone is charged in a cut-off mode, the charging box boosting circuit is closed, and the charging box enters a low-power-consumption working state.
When the cover of the charging box is opened, a Hall switch on the circuit is triggered, a low level is output to the MCU, the MCU provides an enabling signal to enable the DC/DC to boost 5V and keep the 5V voltage for 3 minutes, and after the earphone is put into the charging box within 3 minutes, the earphone starts to be charged; if no earphone is put in within 3 minutes, the boosting IC is closed, and the charging box enters a low power consumption state. At this time, if the earphone needs to be charged, the cover only needs to be opened and closed again.
