Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] see Figure 1-7 , the embodiment of the present invention provides a coil 100 .

[0035] The coil 100 includes a first wire end 1 , a second wire end 2 and a winding group 3 connecting the first wire end 1 to the second wire end 2 .

[0036] In this embodiment, the first wire end 1 is an input port of the coil 100 .

[0037] The second wire end 2 is an output port of the coil 100 . Of course, the first wire end 1 and the second wire end 2 can be interchanged, that is, the first wire end 1 is the output port of the coil 100; the second wire end 2 is the input port of the coil 100 Ports are also available.

[0038] In this embodiment, the winding group 3 includes a stacked first planar winding T3 and a second planar winding B3, and the first planar winding T3 and the second planar winding B3 are concentric along the clockwise or counterclockwis...

Abstract

The invention provides a coil and wire charging equipment, and the periphery of the coil is formed by the parallel winding of four strands of multi-turn outer coils stacked in a first plane winding and a second plane winding, and the inner periphery of the coil is formed by the parallel winding of two strands of multi-turn inner coils stacked in the first plane winding and the second plane winding, thereby enabling the outer coils to fully utilize the peripheral space. Current distribution of the inner coil and the outer coil is more uniform, magnetic field distribution is more uniform, and alternating current resistance of the induction coil is smaller.

Description

【Technical field】 [0001] The present invention relates to the technical field of wireless charging, in particular to a coil using wireless charging and wireless charging equipment. 【Background technique】 [0002] With the continuous development of the application of smart devices. Among the many smart devices, smart devices with wireless charging function are the most eye-catching products. At present, the wireless charger is one of the important wireless charging product equipment. [0003] The wireless charger of the related art adopts the principle of electromagnetic induction, and realizes the energy transmission through the energy coupling through the coil, without the characteristics of the connection of the traditional charging power line. Therefore, it is more and more favored by manufacturers such as mobile phones, tablet computers, and smart watches. [0004] However, the coil part for energy transmission of the wireless charger in the related art has the risk o...
