Problems solved by technology

[0002] Currently, the smart terminal is basically charged with a conventional split charger. The charging specifications and connector definitions are different, resulting in a large waste of charger and data cable resources, and only one smart terminal can be charged at a time; device charging It is necessary to connect the power supply and the cable when charging, and the cable needs to be plugged and unplugged during the charging process, which is inconvenient for the user experience
[0003] Wireless chargers are beginning to appear in the industry. However, because the number of coils in the transmitting coil is fixed, and the devices that need to be charged have different specifications and power requirements, the charging efficiency of wireless chargers cannot reach the optimal value.

Embodiment 1

[0029] A wireless charger with adjustable coil turns, including a transmitting coil, the transmitting coil is composed of N circular coils 1 laminated, the upper part of the circular coil 1 is provided with a slightly convex joint 2, and the lower part of the circular coil 1 is provided with a dimple Pit joint 3; the micro-protrusion joint 2 of the ring coil 1 in the middle layer is embedded in the micro-pit joint 3 of the upper ring coil 1, and the micro-protrusion joint 2 of the uppermost layer and the micro-pit joint 3 of the bottom layer are connected to external wires ; The number of N is 4. The number of N can also be 3, 5 or more according to needs.

[0030] The transmitting coil is composed of N loop coils 1, and the loop coils 1 can be easily added and removed, so the number of loop coils 1 can be adjusted according to the needs, thereby adjusting the transformation ratio of the transmitting coil and the receiving coil, which can make wireless When charging devices w...

Embodiment 2

[0039] A wireless charger with an adjustable number of turns of the coil, including a transmitting coil, the transmitting coil is formed by stacking P circular coils 1, the lower part of the circular coil 1 is provided with a slightly convex joint 2, and the upper part of the circular coil 1 is provided with a dimple Pit joint 3; the micro-protrusion joint 2 of the ring coil 1 in the middle layer is embedded in the micro-pit joint 3 of the upper ring coil 1, and the micro-pit joint 3 of the uppermost layer and the micro-protrusion joint 2 of the bottom layer are connected to external wires ; The number of P is 4.

[0040] It also includes a receiving coil, which is formed by stacking Q loop coils 1, and the number of loop coils 1 in the receiving coil is three. The lower part of the ring coil 1 is provided with a micro-protrusion joint 2, and the upper part of the ring coil 1 is provided with a micro-pit joint 3; the micro-protrusion joint 2 of the ring coil 1 of the middle la...

Abstract

The invention relates to the technical field of wireless charging, in particular to a wireless charger with the adjustable coil number. The wireless charger with the adjustable coil number comprises a transmitting coil. The transmitting coil is formed by N annular coil bodies in an overlapped mode, a micro-protrusion connector is arranged on the upper portion of each annular coil body, a micro-pit connector is arranged on the lower portion of each annular coil body, the micro-protrusion connectors of the annular coil bodies in the middle layers are embedded into the micro-pit connectors of the annular coil bodies in the upper layers, the micro-protrusion connector in the uppermost layer and the micro-pit connector in the lowermost layer are connected with external wires, and the N is larger than three. Due to the fact that the transmitting coil is formed by the N annular coil bodies in the overlapped mode, the annular coil bodies can be conveniently added and removed, the number of the annular coil bodies can be adjusted according to requirements, the transformation ratio of the transmitting coil to a receiving coil is accordingly adjusted, and therefore the charging efficiency can reach the optimal value when devices in different standards and with different powers are charged through the wireless charger.
