Example two
As shown in fig. 4, a charging method for an auto-induction charging bluetooth headset charging box is applied to an auto-induction charging bluetooth headset charging box, and includes:
step S1: judging whether the charging box upper cover 2 is in an opened state or a closed state, if the current magnetic field strength is continuously reduced, the charging box upper cover 2 is in the opened state, and when the current magnetic field strength is reduced to a magnetic working threshold value, the Hall sensing sensor 4 sends a signal to the micro control structure 6, the micro control structure 6 controls to output a high level, if the current magnetic field strength is continuously increased, the charging box upper cover 2 is in the closed state, and when the current magnetic field strength is increased to the magnetic working threshold value, the Hall sensing sensor 4 sends a signal to the micro control structure 6, and the micro control structure 6 controls to output a low level;
in the specific implementation process, the upper charging box cover 2 is in an opened state from a closed state, a pair of attracted magnets is arranged at the buckling position of the upper charging box cover 2 and the lower charging box cover 3, the upper charging box cover 2 is far away from the lower charging box cover 3, the magnetic field generated by the magnets is reduced, the magnetic field strength of the minimum magnetic working threshold is the magnetic field strength when the upper charging box cover 2 and the lower charging box cover 3 are at a distance of 20mm before reaching the farthest distance, the upper charging box cover 2 is in a closed state, the magnetic field strength is the strongest when the upper charging box cover 2 is in the closed state from the opened state to the closed state, the magnets in the buckling position of the upper charging box cover 2 are gradually close to the magnets of the lower charging box cover 3, the two magnets attract each other, the magnetic field strength is gradually increased, when the upper charging box cover 2 and the lower charging box cover 3 are buckled, and the magnetic field strength is the strongest, and the maximum magnetic field strength is before the upper charging box cover 2 and the lower charging box cover 3 are buckled, the magnetic field intensity when the distance between the charging box upper cover 2 and the charging box lower cover 3 is 5 mm.
Step S2: if the charging box upper cover 2 is in an opened state, judging whether a Bluetooth headset is arranged in the charging box body 1 when the charging box upper cover 2 is opened, and if the charging post 53 is detected to have current output, determining that the Bluetooth headset is arranged in the charging box body 1;
in the specific implementation process, bluetooth headset puts into 3 recesses of box lower cover that charges, as long as bluetooth headset contacts post 53 that charges, lithium cell 55 is the bluetooth headset power supply immediately, the output electric quantity, and simultaneously, bluetooth headset's breathing lamp that charges is bright, therefore, bluetooth headset is when charging box body 1, post 53 that charges has current output, insert detection module and detect post 53 that charges whether there is current output, can be accurate and quick judgement out and charge whether there is bluetooth headset in the box body 1.
Step S3: if the charging box body 1 is internally provided with the Bluetooth headset, the charging voltage of the lithium battery 55 in the charging box body 1 is controlled to be rapidly closed from 5V to 0V, the electric quantity display lamp 54 is controlled to be turned off after being kept for 1 minute, and the charging box body 1 judges whether the Bluetooth headset is automatically started and paired when the charging box upper cover 2 is opened;
in the specific implementation process, there is bluetooth headset in the box body 1 that charges, and little control structure 6 controls 55 electric quantity outputs of lithium cell and directly drops to 0V by 5V, prevents to slowly fall down the power supply and causes the damage to the earphone chip, and the power display lamp 54 keeps extinguishing after 1 minute.
Step S31: the Bluetooth headset judges whether current is input or not, if no current is input in the Bluetooth headset, the Bluetooth headset is automatically started, and the main Bluetooth headset and the auxiliary Bluetooth headset are automatically connected in a matched mode;
in the specific implementation process, on the basis of step S3, after the box upper cover 2 that charges was judged to the box body 1 that charges promptly opened, little control structure 6 control lithium cell 55 electric quantity output directly drops to 0V by 5V, and no current input is detected to the bluetooth headset, and the bluetooth headset is automatic to be started up, and the major-minor headset carries out automatic pairing connection.
Step S32: if current input is detected in the Bluetooth headset, the Bluetooth headset keeps a power-off state, and the main Bluetooth headset and the auxiliary Bluetooth headset are not automatically connected in a pairing way;
in the specific implementation process, the 5V of lithium battery 55 electric quantity output does not drop to 0V, and the current input is detected in the Bluetooth headset, and the Bluetooth headset keeps the power-off state, and the main Bluetooth headset and the auxiliary Bluetooth headset are not connected in an automatic pairing mode.
Step S4: if the charging box upper cover 2 is in a closed state, judging whether a Bluetooth headset is arranged in the charging box body 1 when the charging box upper cover 2 is closed, and if the charging post 53 is detected to have current output, determining that the Bluetooth headset is arranged in the charging box body 1;
in the specific implementation process, the detection result is output to the micro control structure 6 in the same step S2.
Step S5: if a Bluetooth headset is arranged in the charging box body 1, the electric quantity display lamp 54 is controlled to be turned off immediately, and meanwhile, the lithium battery 55 is controlled to charge the Bluetooth headset through the charging post 53;
in the specific implementation process, the micro control structure 6 controls the electric quantity display lamp 54 to be turned off immediately, and the micro control structure 6 controls the lithium battery 55 to output electric quantity, so that the Bluetooth headset is charged through the charging post 53.
Step S6: if no bluetooth headset is arranged in the charging box body 1, the electric quantity display lamp 54 is controlled to be immediately turned off.
In the specific implementation process, the charging post 53 does not detect the current output and transmits a signal to the micro control structure 6, and the micro control structure 6 controls the electric quantity display lamp 54 to be immediately turned off.
The invention provides an automatic induction charging Bluetooth headset charging box and a charging method thereof, and the working principle is as follows:
when the charging box is used, the upper cover 2 of the charging box is opened, the Hall sensor 4 detects the change of the magnetic field, the micro-control structure 6 detects whether the charging post 53 passes through the current by inserting the monitoring module, thereby judging whether the Bluetooth headset exists in the charging box body 1 or not, if the Bluetooth headset exists in the charging box body 1, the micro-control structure 6 controls the output electric quantity of the lithium battery 55 to immediately reduce to 0V, the damage to a headset chip caused by slow power failure is prevented, the electric quantity display lamp 54 is turned off after being turned on for 1 minute, if the Bluetooth headset does not exist in the charging box body 1, the Bluetooth headset is put in, the micro-control structure 6 controls the lithium battery 55 to supply power for the Bluetooth headset, the charging breathing lamp of the Bluetooth headset is turned on, the electric quantity display lamp 54 is turned on to display charging, the upper cover 2 of the charging box is turned off immediately, the Bluetooth headset exists in the charging box body 1, the micro, after bluetooth headset was full of the electricity, bluetooth headset charges and breathes the lamp and extinguish, avoids the risk of earphone outage start, and this bluetooth headset charges the box and has whether there is bluetooth headset in the auto-induction box body 1 that charges to effectively carry out auto-induction to bluetooth headset and charge, increase automatic intelligent effect, reinforcing result of use.
