Examples

Referring to fig. 1, which shows a functional block diagram of a charging stand according to an embodiment of the present invention, as shown in fig. 1, the charging stand includes a micro switch 110, a processor 120 and a monostable trigger circuit 130, wherein the micro switch 110 and the monostable trigger circuit 130 are electrically connected to the processor 120 respectively;

the monostable trigger circuit 130 is used for controlling the power supply to start supplying power through the processor 120 when the microswitch 110 detects that the host is inserted. Accordingly, the monostable trigger circuit 130 does not control the power supply when the microswitch 110 does not detect the host insertion.

In this embodiment, the power supply may be a built-in power supply in the charging cradle or an external power supply. The built-in power supply can be a replaceable battery, a rechargeable non-replaceable battery, a rechargeable and replaceable battery or a non-replaceable and non-rechargeable battery; the rechargeable battery can be a lithium battery, a nickel-cadmium battery, a nickel-hydrogen battery, a lead storage battery, a lithium iron battery and the like; the external power source may be an alternating current, a charge pal, or other type of external power source. The present embodiment is not limited to the type of the power supply.

Referring to fig. 2, the charging stand includes a charging base 201 and a micro switch 202 disposed on the surface of the charging base, and the schematic diagram shows that when the host 203 is inserted into the charging stand, as shown in the figure, when the host 203 is inserted into the charging base 201, the micro switch 202 is closed under the action of the host 203, so as to control the power supply to start supplying power. The cross section of the charging base 201 is concave, the processor 120 and the monostable trigger circuit 130 in the embodiment of fig. 1 are arranged inside the charging base 201, and the micro switch 202 is arranged on the concave upper surface of the charging base 201.

In the above embodiments, referring to fig. 3, the one-shot circuit includes the first transistor Q1, the second transistor Q2, and the one-shot U2; the first triode Q1 is connected with the microswitch 301 and the second triode Q2, and the second triode Q2 is connected with the monostable trigger U2; the monostable trigger U2 controls the power supply to start supplying power when the microswitch 301 detects that the host is plugged in. The monostable trigger circuit 303 converts the opening and closing of the microswitch 301 into pulse output, and controls whether the power supply supplies power or not according to the height of the pulse output. For example, when the micro switch 301 is turned off, the monostable trigger circuit 303 outputs a low-level pulse power supply to supply no power; when the microswitch 301 is closed, the monostable trigger circuit 303 outputs a high level pulse to electrify the power supply for power supply, the high level pulse is a single high level pulse without frequency,

in practical implementation, referring to fig. 3, the first transistor Q1 is PNP, the second transistor Q2 is NPN, the base of the first transistor Q1 is connected to the micro switch 301, the collector of the first transistor Q1 is connected to the base of the second transistor Q2, the emitter of the first transistor Q1 is connected to the power output terminal, the collector of the second transistor Q2 is connected to the monostable flip-flop U2, and the emitter of the second transistor Q2 is connected to the power output terminal. Alternatively, in an actual circuit, the first transistor Q1 may be connected to the micro switch 301 through a resistor R6, and the base of the first transistor Q1 may be connected to the power output terminal through a capacitor C6 and a resistor R5 connected in parallel; the base of the second transistor Q2 may be connected to the collector of the first transistor Q1 through a resistor R7 and to ground through a capacitor C7 and a resistor R8, and the emitter of the second transistor Q2 may be connected to the power supply output through a resistor R9. With reference to the circuit diagram shown in fig. 3, when the host is not plugged in, the micro switch 301 is in a normally open state, the first diode Q1 and the second diode Q2 are cut off, and the output of the monostable flip-flop U2 is at a low level; when the host is plugged in, the microswitch 301 is switched from a normally open state to a normally closed state, the first triode Q1 and the second triode Q2 are conducted, and the monostable trigger U2 outputs a single high-level pulse.

In practical implementation, when the power required by the load cannot be directly provided by the power supply, the charging dock may further include a first power conversion circuit 304 for converting the power supply into the power required by the load, and in order to control whether the load is powered up through the monostable trigger circuit 303, an output terminal of the monostable trigger U2 in the monostable trigger circuit 303 may be connected to an enable terminal of the first power conversion circuit 304, and the other terminal of the first power conversion circuit 304 is connected to the load. For example, the power supply is 5V, and the power required by the load is 3.5V, the first power conversion circuit 304 is configured to convert the 5V power output into a 3.5V power output. Referring to fig. 3, an output terminal of the monostable flip-flop U2 may be connected to the first power conversion circuit 304 through a resistor R13, an output terminal of the monostable flip-flop U2 is grounded through a pull-down resistor R14, and the specific circuit of the first power conversion circuit 304 is as shown in fig. 3, which is not limited in this embodiment. Referring to fig. 3, when the host is not plugged in, the monostable flip-flop U2 cannot enable the enable terminal of the first power conversion circuit 304 due to the low level output by the pull-down resistor R14, so that the first power conversion circuit 304 does not perform power conversion, and the load is not powered on; when the host is plugged in, the input of the monostable flip-flop U2 is switched from high level to low level, and a falling edge is formed, so that the U2 outputs a single high level pulse, and at this time, the enable terminal of the first power conversion circuit 304 starts to perform power conversion under the enable of the single high level pulse of the monostable flip-flop U2, and the load is powered on.

In addition, similar to the above implementation, when the power supply required by the monostable trigger circuit 303 cannot be directly provided by the power supply, a second power conversion 302 circuit for converting the power supply into the power supply required by the monostable trigger circuit 303 may be further included in the cradle. In practical implementation, the second power conversion circuit 302 is connected to the monostable flip-flop circuit 303, and a specific circuit structure of the second power conversion circuit 302 is shown in fig. 3, which is not limited in this embodiment.

In an optional embodiment, the cradle further comprises a third power conversion circuit, and the third power conversion circuit is connected to the load and is used for converting the power supply into the power required by the load.

Fig. 4 is a schematic diagram showing the connection of the functional modules connecting the host and the charging cradle when the power required by the monostable trigger circuit and the power required by the load cannot be directly provided by the power supply, that is, the charging cradle includes the first power conversion circuit and the second power conversion circuit at the same time (the charging cradle is provided with a rechargeable lithium battery for example).

In addition, in order to avoid that the service life of the power supply is affected by the over-discharge of the power supply, in actual implementation, when the electric quantity of the power supply is lower than the set electric quantity, the charging dock may also stop supplying power through software, which is not limited in this embodiment.
