The wireless earphone box of an embodiment shown in fig. 1 includes an outer case 10, an inner case 20, a power supply 30, a charge and discharge management module 40, a voltage step-up and step-down module 50, a power detection module 60, a charge interface 70 provided on the outer case 10, and a discharge interface 80 provided on the inner case 20.
A first accommodating cavity 101 is arranged between the outer shell 10 and the inner shell 20, the power supply 30, the charge and discharge management module 40, the lifting pressure module 50 and the electric quantity detection module 60 are all arranged in the first accommodating cavity 101, a second accommodating cavity 102 for accommodating a wireless earphone (not shown in the figure) is arranged on the inner shell 20, the discharge interface 80 is positioned on the bottom wall or the side wall of the second accommodating cavity 102, and when the wireless earphone is accommodated in the second accommodating cavity 102, the discharge interface 80 is electrically connected with the wireless earphone.
The power supply 30 is electrically connected with the buck-boost module 50, the buck-boost module 50 is electrically connected with the charging interface 70 and the discharging interface 80 respectively, the electric quantity detection module 60 is electrically connected with the power supply 30 and the discharging interface 80 respectively, and the charge-discharge management module 40 is electrically connected with the power supply 30, the buck-boost module 50 and the electric quantity detection module 60 respectively.
In this embodiment, the wireless earphone box may be a conventional tws wireless earphone box.
The power supply 30 includes a battery cell and a protection circuit. The cells are typically lithium ion batteries.
The battery core is directly electrically connected with the protection circuit, and the electric connection between any other modules and the battery core is realized through the protection circuit.
The protection circuit provides the last hardware level protection for the cell 120, which typically works in the event of a software protection failure. Most of the current commercial power supplies are provided with protection circuits. In some embodiments, the protection circuit 130 may be omitted, and the protection of the battery cell is implemented through software protection.
The charge and discharge management module 40 manages the charge and discharge of the wireless earphone case. The charge and discharge management module 40 may be an mcu control chip.
The buck-boost module 50 is used to boost and buck during charge and discharge.
Specifically, an external power source (not shown) charges the power source 30 electrically connected to the charging interface 70 through the step-up and step-down module 50, and the power source 30 charges the wireless earphone electrically connected to the discharging interface 80 through the step-up and step-down module 50.
Preferably, the BUCK-BOOST module 50 may be a BUCK-BOOST circuit.
The power detection module 60 is used for detecting the power of the power supply 30 and detecting the power of the wireless earphone electrically connected to the discharge interface 80.
The power detection module 60 may be integrated with the charge and discharge management module 40 in one chip, or may be a separate detection chip.
The charging interface 70 may generally be a Type-C interface or a Micro USB interface.
The discharge interface 80 is typically 2-4 pogo pin spring pins. Since two wireless headphones are typically mounted in the wireless headphone case, there are two discharge interfaces 80 in this embodiment.
The discharging interface 80 is electrically connected to the wireless earphone, and when the charging interface 70 is electrically connected to the external power supply, the charging/discharging management module 40 is configured to control the external power supply to charge the power supply 30 to a power level higher than a second preset value when the power level of the power supply 30 is lower than the first preset value, and control the power supply 30 to not charge the wireless earphone, and further control the external power supply to not charge the power supply 30 when the power level of the power supply 30 is higher than the first preset value and the power level of the wireless earphone is lower than a third preset value, and control the power supply 30 to charge the wireless earphone to a power level higher than a fourth preset value.
It should be noted that, whether the external power source charges the power source 30 and whether the power source 30 charges the wireless earphone are implemented by controlling the buck-boost module 50 by the charge-discharge management module 40, for example, the buck-boost module 50 may be directly controlled to disconnect the corresponding circuit.
When the wireless earphone box is in use, the discharging interface 80 is electrically connected with the wireless earphone, and the charging interface 70 is electrically connected with the external power supply, when the electric quantity of the power supply 30 is lower than a first preset value, the external power supply charges the power supply 30 until the electric quantity of the power supply 30 is higher than a second preset value, and at the moment, the power supply 30 does not charge the wireless earphone, when the electric quantity of the power supply 30 is higher than the first preset value, and the electric quantity of the wireless earphone is lower than a third preset value, the external power supply does not charge the power supply 30, and the electric quantity of the power supply 30 charges the wireless earphone until the electric quantity of the wireless earphone is higher than a fourth preset value.
When the wireless earphone box with insufficient electric quantity is connected with an external power supply, and the wireless earphone with insufficient electric quantity is contained in the wireless earphone box, the wireless earphone box can charge the power supply 30 of the wireless earphone box for a short period of time, and then the power supply 30 of the wireless earphone box charges the wireless earphone, so that the overlong charging time of the wireless earphone can be avoided, and on the other hand, the wireless earphone box can be prevented from being discharged while being washed, and the service life of the wireless earphone box is not reduced.
If the lithium ion battery is in a state of extremely low electric quantity, the performance of the lithium ion battery can be damaged.
Specifically, when the power of the power supply 30 in the wireless earphone box is extremely low (for example, less than 5%, or even less than 3%), if the power supply 30 continues to charge the wireless earphone, on the one hand, the wireless earphone cannot be charged sufficiently, and on the other hand, the further reduction of the power also causes the performance of the battery cell of the power supply 30 to be damaged.
Specifically, the ratio of the first preset value to the rated power of the power source 30 may be 5-25:100.
The first preset value may be set according to the actual situation. In general, it is not recommended to set the ratio of the first preset value to the rated power of the power source 30 to be less than 5% in order to avoid damaging the battery cells of the power source 30.
Preferably, the ratio of the second preset value to the rated power of the power supply 30 is 5-35:100.
To ensure a faster implementation of charging the wireless headset, the second preset value is typically a little larger than the first preset value.
Preferably, the ratio of the second preset value to the first preset value is 130-200:100.
In a particular embodiment, the second preset value is equal to the first preset value. In this embodiment, the first preset value cannot be set too low to avoid overdischarging the battery 30, and it should be ensured that the battery of the power supply 30 still has sufficient power after charging the wireless headset. At this time, the ratio of the first preset value to the rated power of the power supply 30 may be 12-25:100.
For example, the first preset value and the second preset value may each be 12% of the rated power of the power supply 30. When the power of the power supply 30 is less than 10%, the power supply 30 is charged to 12% first, and then the power supply 30 charges the wireless earphone to a power level higher than a fourth preset value (the wireless earphone is not necessarily in a full power state at this time), and the power level in the power supply 30 is still far greater than 5% (e.g. 8%, 10% etc.).
Preferably, the ratio of the third preset value to the electric quantity of the wireless earphone is 20-100:100.
More preferably, the ratio of the third preset value to the electric quantity of the wireless earphone is 20-60:100.
The charge and discharge management module 40 is further configured to control the external power supply to charge the power supply 30 to a power supply 30 with a power level higher than a second preset value and control the power supply 30 not to charge the wireless headset when the power level of the power supply 30 is higher than the first preset value and the power level of the wireless headset is higher than the third preset value.
Preferably, the ratio of the fourth preset value to the electric quantity of the wireless earphone is 20-70:100.
Preferably, the ratio of the fourth preset value to the third preset value is 102-150:100.
In a particular embodiment, the fourth preset value is equal to the third preset value. At this time, when the ratio of the third preset value to the electric quantity of the wireless earphone is 100:100, the power supply 30 needs to fully charge the electric quantity of the wireless earphone after being charged to the electric quantity higher than the second preset value.
It should be noted that, when the power of the power supply 30 is higher than the second preset value, the power supply 30 charges the wireless earphone.
The above embodiments represent only a few embodiments of the present invention, which are described in more detail and are not to be construed as limiting the scope of the present invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
