Specific implementation mode

The utility model is described in detail in the following with reference to the drawings and specific embodiments.

Embodiment 1：

The utility model provides a kind of novel on-vehicle high power wireless charging device, as shown in Fig. 2, the charging unit by with Lower component forms：

Main casing：It is made of the upper cover 1 of plastic material and lower casing made of iron 5, and upper cover 1 and lower casing 5 pass through spiral shell Bolt assembles, and upper cover 1 and lower casing 5 are rectangular member, and the side of upper cover 1 is equipped with 4 companies with holes to fixing bolt Fishplate bar, lower casing 5 also are provided with 4 connecting plates with holes in the connecting plate corresponding position of side and upper cover 1, the two by bolt into Row fastening, ensures stability and the safety of internal component；

Wireless charging element：Include the ferrite coil 2 from top to bottom set gradually in main casing, die-cast metal shell 3 The through-hole on die-cast metal shell 3 is passed through to be connect with PCBA board 4 with the connector of PCBA board 4, ferrite coil 2；

Die-cast metal shell 3 is an open rectangular aluminum metal-back below, is buckled in PCBA board 4, to from top Protection and metal electromagnetic shielding are carried out to PCBA board 4；

The upper surface of die-cast metal shell 3 is equipped with the square groove 31 being harmonious with 2 shape of ferrite coil, ferrite coil 2 It is placed in square groove 31 and fixed, the metal-back of aluminum has separated PCBA board 4 and ferrite coil 2, reduces ferrite lines Enclose the electromagnetic interference of 2 pairs of PCBA boards 4；

In the present embodiment, in order to preferably radiate, lower casing 5 selects metal alumiaum article, the thickness of lower casing 5 to select 1mm.

Since the top of PCBA board 4 is aluminum die-cast metal shell 3, lower part is aluminum lower casing 5, completely by metal screen It covers, therefore enhances electromagnetism interference performance, can adapt to more severe electromagnetic environment.

Embodiment 2：

As shown in figure 3, the shape of die-cast metal shell 3 is consistent with upper cover 1 and lower casing 5, but area is less than 1 He of upper cover Lower casing 5, and in the surrounding of die-cast metal shell 3 there are certain gap, 3mm is chosen in this example,

Multiple floors 32 arranged side by side are additionally provided with along the side of die-cast metal shell 3, floor 32 is perpendicular to die-cast metal shell 3 Side setting, and be just stuck in when mounted in the gap between die-cast metal shell 3 and upper cover 1 and lower casing 5, the floor On the other hand 32 can both increase heat dissipation area, and not only ensure that clamping fixed but also can assist when mounted with 5 clamping of lower casing Heat dissipation, is allowed to adapt to the wireless charging operating mode of higher power.

The round-meshed otic placode passed through for 2 joint line of ferrite coil, device are additionally provided with along the side of die-cast metal shell 3 Thickness is less than the thickness of floor 32, can also auxiliary heat dissipation.

In this example, lower casing 5 is metal iron piece, in order to preferably radiate and effectiveness, thickness are 0.5mm:, remaining structure and embodiment 1 are consistent.

Embodiment 3：

In this example, since the case where being installed jointly with external connector can be encountered, lower casing 5 is equipped with to put Set the groove 51 of aerial lug, which matches with external connector shape, 51 shape of this example further groove be it is rectangular, remaining Structure is same as Example 1.

Embodiment 4：

In this example, when excessive superelevation component is installed in PCBA board 4 the case where, the volume of region extension lower casing 5 is needed The shape of PCBA board 4 is adapted to, therefore, lower casing 5 is equipped with to adapt to the protrusion 52 that PCBA board 4 installs occupy-place, the protrusion 52 be rectangular, remaining structure is same as Example 1.

The utility model is only made of 5 critical pieces, possesses less number of parts, and assembly technology is simple, when assembly Between it is less, reduce artificial, improve efficiency, and possess better thermal diffusivity, Electro Magnetic Compatibility and protection safety, by It is all made of the better metallic article of heat dissipation in die-cast metal shell and lower casing, compared to plastic shell before, heat dissipation performance is more It is good, and PCBA board is placed in metal space using following open rectangular aluminum metal-back and metal lower casing, electromagnetic screen It is more preferable to cover effect, and metal shell is more solid more wear-resisting than plastic casing, since thermal diffusivity is good, is fully able to adapt to The wireless charging operating mode of 15W or more, more existing device have greatly improved.
