In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," "sleeved," and the like are to be construed broadly, e.g., as meaning connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The present invention will be further explained with reference to the accompanying drawings.

Example 1:

as shown in fig. 1-9, a vehicle-mounted wireless charger with voltage and current display comprises a charger body 3, wherein one end of the charger body 3 is provided with a cigar lighter de-electrifying anode 1, and the side surface of the charger body 3 is provided with a cigar lighter de-electrifying cathode 2; the other end of charger body 3 is equipped with wireless charger apron 9, and interface 5 and the wireless charger apron 9 of voltage electric current display screen 6 embedding of charging still are equipped with control circuit board 4 and wireless coil 7 in the charger body 3, and is specific, is equipped with control circuit, power supply circuit, voltage electric current sampling circuit, voltage electric current display circuit, wireless charging circuit and the interface circuit that charges on control circuit board 4. Cigar lighter anodal 1 that removes electricity, cigar lighter negative pole 2, the interface 5 that charges, voltage electric current display screen 6 and wireless coil 7 all with control circuit board 4 electric connection, definitely says so, cigar lighter positive pole that removes electricity 1, cigar lighter negative pole 2 are connected power supply circuit's positive negative pole respectively, wireless charging circuit connects wireless coil 7, the interface circuit connection interface 5 that charges. Furthermore, the power circuit, the voltage and current sampling circuit, the voltage and current display circuit, the wireless charging circuit and the charging interface circuit are respectively and electrically connected with the control circuit. In order to prevent the charging device from sliding on the wireless charger cover plate 9, an anti-slip silica gel 8 pad is further arranged on the wireless charger cover plate 9. Correspondingly, the charging interface 5 is the most common USB interface, and one charging interface is provided on the charger.

In the embodiment, the voltage current display 6 is a liquid crystal display.

In a specific embodiment, the cigar lighter de-energizing anode 1 and the cigar lighter de-energizing cathode 2 are both telescopic circular metal cylinders, wherein the metal cylinder where the cigar lighter de-energizing cathode 2 is located is used for clamping the charger to the automobile cigar lighter.
