Abstract
Disclosed in the utility model is a wireless charging transmitting coil assembly comprising a transmitting coil and magnetic cores. The transmitting coil has an annular structure; and the magnetic cores have structures in U-shaped bar shapes. Grooves are formed in the magnetic cores; the transmitting coil is embedded into the grooves of the magnetic cores; and the magnetic cores are dispersed and distributed at the transmitting coil. According to the wireless charging transmitting coil assembly, the magnetic core structures are small and exquisite, so that the weight of the assembly is reduced and the cost is saved. Moreover, the magnetic field where the magnetic cores are gathered is transmitted from one ends to the other ends of the magnetic cores and the distance to the magnetic field receiving portion is short, thereby improving the wireless charging efficiency.
Description
Technical field
The utility model relates to a kind of wireless charging transmitting coil assembly.
Background technology
At present, most of wireless charging transmitting coil assemblies are all to use a magnetic core that bulk is square, and transmitting coil is fixed on square magnetic core, and this has just caused the weight ratio of coil heavier, and cost is higher.The magnetic field that square core is assembled in addition outwards sheds from four edges, also has a segment distance from receiving unit, and receiving efficiency is not high, causes loss.
Summary of the invention
The technical problems to be solved in the utility model is to provide that a kind of cost is lower, weight is lighter, the wireless charging transmitting coil assembly that magnetic field congregational rate is good.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: this wireless charging transmitting coil assembly comprises transmitting coil and magnetic core, described transmitting coil is circulus, described magnetic core is U-shaped list structure, described magnetic core is provided with groove, described transmitting coil is embedded in the groove of magnetic core, and described magnetic core is distributed on transmitting coil.
In order to reach good magnetic field congregational rate, as of the present utility model preferred, described transmitting coil is circular ring.
As of the present utility model preferred, described magnetic core circular array distributes.
The utility model adopts technique scheme: the core structure of this wireless charging transmitting coil assembly is small and exquisite, alleviate the weight of wireless charging transmitting coil assembly, provide cost savings, and send to the other end from magnetic core one end in the magnetic field that magnetic core is assembled, more approach magnetic field receiving unit, improved wireless charging efficiency.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the present invention is further described in detail.
Fig. 1 is a kind of wireless charging transmitting coil of the utility model assembly structural representation;
Fig. 2 is the magnetic texure schematic diagram of a kind of wireless charging transmitting coil of the utility model assembly.
Embodiment
As shown in Figure 1, 2, this wireless charging transmitting coil assembly comprises transmitting coil 1 and magnetic core 2, and described transmitting coil 1 is circular ring, and it is formed by enamelled wire coiling multiturn in same plane, and centre is provided with through hole.Magnetic core 2 is U-shaped list structure, and its two ends are provided with projection, forms groove between projection.Transmitting coil 1 is embedded in the groove of magnetic core 2, and magnetic core 2 circular array formal distributions are on transmitting coil 1.The magnetic field of magnetic core 2 polymerizations is by the outside scattering of magnetic core 2 end to end, and the closer to receiving terminal, wireless charging efficiency will be higher.
