Specific embodiment
The embodiment of the present invention is described in detail below in conjunction with attached drawing, but the present invention can be defined by the claims
Implement with the multitude of different ways of covering.
One aspect of the present invention provides a kind of automobile wireless charging magnetic core installation fixed structure, wireless for simplifying
It is wireless to be suitable for new-energy automobile (pure electric vehicle, hybrid vehicle) for the fixed form of charge power emitter coil and magnetic core
The production technology of charger.
Automobile wireless charging magnetic core installation fixed structure includes: shell 1, coil 2 and magnetic core 3, shape on the shell 1
At the first recessed portion having for placing the magnetic core 3, the magnetic core 3 is placed in first recessed portion, first recess
The bottom surface in portion is formed as the mounting surface 4 for being used to support the magnetic core 3, is formed with and is used in the circumferential side wall of first recessed portion
To the first limit ribs 5 of the magnetic core 3 limit, a part of the bottom surface is formed as using to the direction far from the magnetic core 3
In the second recessed portion 6 for placing the coil 2, the coil 2 is placed in second recessed portion 6.The mounting surface of magnetic core can
Gum is with fixed magnetic core, it is preferable that excessive glue groove 8 is also provided on the bottom surface of first recessed portion, to discharge extra gum.
In the above-mentioned technical solutions, magnetic core 3 is supported on mounting surface 4, and coil is then mounted in the second recessed portion 6, because
And can guarantee the spacing between magnetic core and coil well, the first limit ribs 5 limit the position of magnetic core 3, prevent magnetic
About 3 core misplaces, and coil and magnetic core is made to be able to achieve automated production.
By adopting the above-described technical solution, this invention ensures that spacing between coil and magnetic core, and have on shell
The muscle position for preventing magnetic core from deviating, ensure that magnetic core installation site, has the characteristics that compact dimensions.
