Abstract
The utility model discloses a wireless microphone charging device, which comprises a wireless microphone body and a charging box body. The wireless microphone body is internally provided with an output coil circuit, a charging conversion circuit and a rechargeable battery, wherein the output coil circuit is connected with the charging conversion circuit, and the charging conversion circuit is connected with the rechargeable battery. The charging box body is internally provided with an input coil circuit and a light sensing switch. The surface of the charging box body is further provided with an indicator lamp and a DC input interface. When the wireless microphone is placed in a charging box, the light sensing switch in the charging box is triggered, electromagnetic energy generated by an output coil is sensed by an input coil, the electromagnetic energy is converted into electric energy through the charging conversion circuit, and the electric energy is transmitted to the rechargeable battery of the wireless microphone. The wireless microphone charging device is simple in structure, reasonable in design, and convenient to use, adopts a wireless non-contact charging mode, and can enable products to be sealed, thereby being waterproof and dustproof.
Description
Technical field
The utility model relates to a kind of charging device, is specifically related to a kind of non-contact charger of wireless microphone.
Background technology
The wireless charging technology is fully not by electric wire, the wireless charging Technology origin is in the wireless power tranmission techniques, to carry out a kind of technology that energy transmits by electromagnetic field or electromagnetic wave, basic principle is all to establish a coil at the sending and receiving end, the transmitting terminal coil connects cable power, and the generation electromagnetic energy, receiving terminal is coil-induced to electromagnetic energy, electromagnetic energy is changed into electric energy charge to device battery.
The wireless microphone charging modes is divided into two kinds at present: a kind of external plug-in charger, another mode base type charging modes; Different equipment has different charging inlets; need to change different chargers during charging; if forget charging, the equipment placement location is incorrect or operate incorrect; the direct normal use that affects equipment of meeting; therefore normally move for assurance equipment in school or mechanism; need every day and send special messenger's training in rotation to be charged to wireless device replacing battery or to equipment, use very inconvenience.
The utility model content
The utility model purpose: the purpose of this utility model is in order to solve deficiency of the prior art, a kind of wireless microphone charging device simple in structure, easy to use to be provided.
Technical scheme: a kind of wireless microphone charging device described in the utility model, comprise wireless microphone body and charging box body, be provided with output winding circuit, charging conversion circuit and rechargeable battery in the described wireless microphone body, described output winding circuit is connected with described charging conversion circuit, and described charging conversion circuit is connected with described rechargeable battery; Be provided with input coil circuit and light sensing switch in the described charging box body, described charging box body surface also is provided with indicator light and direct current input interface.
As preferably, described output winding circuit comprises two groups of output windings that are connected in parallel each other, and described output winding is located on the wireless microphone inner body wall.
As preferably, described input coil circuit comprises two groups of input coils that are connected in parallel each other, and described input coil is located on the charging box inner body wall.
As preferably, described charging box body also is connected with external constant voltage dc source by the direct current input interface.
Operation principle of the present utility model is: when the wireless microphone body is put into the charging box body, trigger the intrinsic light sensing switch of charging box, then produce electromagnetic energy by input coil induction output winding, and convert electromagnetic energy to electric energy by charging conversion circuit, send electric energy to rechargeable battery at last, thereby wireless microphone is charged.
Beneficial effect: the utility model is simple in structure, and is reasonable in design, easy to use, adopts wireless contactless charging mode, can make the product sealing, water proof and dust proof.
