Detailed Description
The utility model is described in further detail below with reference to the figures and the specific embodiments. Advantages and features of the present invention will become apparent from the following description and from the claims. It is to be noted that the drawings are in a very simplified form and are each provided with a non-precise ratio for the purpose of facilitating and clearly facilitating the description of the embodiments of the present invention.
It should be noted that all the directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.
Referring to fig. 1 to 5, the core of the present invention is to provide a multi-surface wireless charging coil device with a common shielding material, which comprises a device body 1 and a plurality of charging coils 3.
The apparatus body 1 is made of a magnetic shield material, and ferrite is used in the present embodiment. The device body 1 is provided with a plurality of mounting surfaces, at least one mounting surface is provided with accommodating grooves 2, and each accommodating groove 2 is internally provided with a charging coil 3.
That is, the shape of the apparatus body 1 may be various, and may be a regular cube, a polyhedral cube, or an irregular shape. The shape of the installation surface can be determined according to the number of the accommodating grooves 2 required to be arranged, or the actual wireless charging direction, and the specific orientation of the installation surface can be determined according to the wireless charging direction.
Each charging coil 3 is disposed in the accommodation groove 2 of each installation surface of the device body 1, and magnetic shielding is achieved through the shared device body 1, so that mutual interference is prevented. That is to say, utilize magnetism shielding material to shield the theory of operation of opening the magnetic circuit all around, when reducing 3 direct couplings of charging coil, the eddy current loss of 3 direct magnetic leakage of charging coil 3 and charging coil.
