The size for the sample rate current for flowing through sampling resistor R21 is calculated, charging valve is sent to by the output terminal OUT of current detecting chip U3
Module U1 is managed, to judge whether wearable device 2 is fully charged according to the size of sample rate current.One kind as the present embodiment is excellent
Designing scheme is selected, when charge management module U1 detects that the sample rate current is less than given threshold, the given threshold is preferred
The value between 1mA ~ 2mA then can be determined that the wearable device charging has been expired.
The sampling resistor R21 preferably uses the precision resistance that resistance value is 1% for 60m Ω, error precision, wireless to reduce
The power consumption of earphone 1 improves charge efficiency.
The present embodiment is also associated with first resistor R25 and second resistance in the output terminal OUT of the current detecting chip U3
R28, the output terminal OUT of the current detecting chip U3 are grounded by first resistor R25, are charged by second resistance R28 connections
The analog-to-digital conversion interface ADC of management module U1, and pass through filter capacitor C10 and be grounded.Pass through adopting for current detecting chip U3 outputs
Sample electric current can be converted into sampled voltage via first resistor R25 and second resistance R28, after filtered capacitance C10 filtering, transmission
To the analog-to-digital conversion interface ADC of charge management module U1, digital signal is converted analog signals into, realizes charge management module U1
Identification to sample rate current size.
The inductive signal CHECK_IN exported by Hall sensor 13 can be transmitted to the charge management module U1, profit
With insert state of the charge management module U1 detection wearable devices 2 on wireless headset 1.
With reference to Fig. 1-Fig. 3, the wireless headset 1 of the present embodiment and the cooperation charging process of wearable device 2 are carried out
It elaborates.
The present embodiment is bluetooth headset with wireless headset 1, and wearable device 2 is illustrates for smartwatch.
When needing to charge to smartwatch 2, by the pad 22 of smartwatch 2 and the electric connector of bluetooth headset 1
11, such as the connection of pogo pin connectors, and smartwatch 2 is pull-in on bluetooth headset 1 using the magnet 23 in smartwatch 2
On.
Hall sensor 13 in bluetooth headset 1 is when detecting that magnet 23 is attracted on bluetooth headset 1（That is, magnet 23
Apart from Hall sensor 13 it is close enough when）, Hall sensor 13 generate inductive signal CHECK_IN be sent in bluetooth headset 1
The charge management module U1 in portion.The charge management module U1, which can be selected specifically, has the function of that the Bluetooth chip of Charge Management is real
It is existing, to simplify circuit design.
Charge management module U1 is after inductive signal CHECK_IN is received, it is believed that has smartwatch 2 to be inserted into bluetooth ear
On the pogo pin connectors 11 of machine 1.At this point, charge management module U1 detection bluetooth headset 1 charging interface 14 on whether
There is external charging equipment access, if so, then performing subsequent charging process；Otherwise, present situation is kept.
Charge management module U1 puts switch control signal POWER_EN by high level first after determining to enter charging process
Low level is jumped to, controls P-channel metal-oxide-semiconductor Q1 saturation conductions, connects the charging current transmission line of smartwatch 2, for intelligence
Wrist-watch 2 charges.At the same time, charge management module U1 connects the charge circuit of battery U2, is filled for the battery U2 in bluetooth headset 1
Electricity.
The size of current that charge management module U1 detections are accessed by charging interface 14, if the access electric current of charging interface 14
During more than or equal to the sum of charging current needed for bluetooth headset 1 and smartwatch 2, then it is assumed that the external charging with charging interface 14
Equipment is adapter, at this point, battery U2 is kept to be connected with the charge circuit of smartwatch 2, using external adapter to bluetooth
2 synchronous charging of earphone 1 and smartwatch, to accelerate the charging rate of the two.And when the charge management module U1 detect it is logical
When crossing the electric current of the access of charging interface 14 less than the sum of charging current needed for bluetooth headset 1 and smartwatch 2, then it is assumed that
It is host with the external charging equipment of charging interface 14.At this point, charge management module U1 is first turned off the charge circuit of battery U2,
The electric current of its power output end POWER_OUT is blocked to export, stops charging to battery U2, preferential connecing using charging interface 14
Enter electric current to charge to smartwatch 2.
During individually being charged to smartwatch 2, charge management module U1 is real-time by current detection circuit
The charging current of smartwatch 2 is detected, when charging current is less than given threshold, when being, for example, less than 2mA, it is believed that intelligent hand
Table 2 fills with electricity.At this point, charge management module U1 puts switch control signal POWER_EN by low transition to high level,
P-channel metal-oxide-semiconductor Q1 cut-offs are controlled, the charging current transmission line of smartwatch 2 is cut off, stops charging for smartwatch 2.And
Afterwards, charge management module U1 connects the charge circuit of battery U2, i.e., by its power output end POWER_OUT output currents, is
Battery U2 chargings in bluetooth headset 1, until battery U2 is fully charged, just complete time-sharing charging process as a result,.
When charging equipment is host, wearable device 2 and wireless headset 1 are controlled using time-sharing charging, it can be effective
The charging duration of wearable device 2 and wireless headset 1 is controlled, improves the satisfaction of user.
Using the above-mentioned designing scheme of the present embodiment, a power supply adaptor can only be configured and meet wearable device simultaneously
2 and the charge requirement of wireless headset 1, it not only contributes to save adapter resources, reduces the use cost of user, and charging
In the process, wearable device 2 can be directly ridden on wireless headset 1, then improves the portability of charging, user is facilitated to take
Band.
Certainly, the above description is not intended to limit the present invention, and the utility model is also not limited to the example above,
The variations, modifications, additions or substitutions that those skilled in the art are made in the essential scope of the utility model,
It should also belong to the protection scope of the utility model.
