Embodiment

Before describing the embodiments in more detail, it should be understood that the invention is not restricted to institute hereafter or in accompanying drawing in the application The detailed construction or arrangement of elements of description.The present invention can be the embodiment that other manner is realized.Furthermore, it is to be understood that this paper institutes The wording and term used is solely for describing purposes, should not the explanation of being construed as limiting property." comprising " used herein, "comprising", The similar wording such as " having " is meant comprising items listed thereafter, its equivalent and other additional things.Particularly, description is worked as When " certain element ", the quantity that the present invention does not limit the element can also include multiple as one.

As shown in Figure 1-2, a kind of wireless charger 10, including housing 11, the wireless charging mould being arranged in the housing 11 Block 16 and radiating module 15, the wireless charging module 16 are arranged with horizontal direction interval of the radiating module 15 along the housing Cloth, the housing 11 include upper lid 12, lower cover 14 and the side wall 13 of the connection upper lid and lower cover, set in the side wall logical Wind portion 131, the ventilation unit 131 are made up of several bar shaped air vents, for the heat of enclosure interior to be taken to outside housing.

In the present embodiment, the radiating module 15 is blower module, and the upper lid 12 is corresponding with the radiating module 15 Position is additionally provided with a ventilation unit 121, and the ventilation unit 121 is formed by several vertical bar shape air vents, when the blower module During 15 work, wind can come in from the air vent 131 of the side wall 13, by fan, from the air vent positioned at the upper lid 12 121 go out, so as to take away heat.It is appreciated that the ventilation hole shape of the ventilation unit 121 is unlimited, such as can be multiple circles Shape aperture is arranged in circular pattern as shown in Figure 1, or the pattern of arrangement squarely or other shapes.In a word, as long as setting With 15 corresponding through-hole structure of blower module.

The wireless charging module 16 includes coil module 161 and circuit board 162, and the circuit board 162 is middle hollow out Loop configuration, the coil module 161 is embedded in engraved structure, and a water is substantially arranged in annular circuit board 162 In plane, and coil module 161 electrically connects with circuit board 162, such as is electrically connected by wire.

The housing 11 is in flattened oval shape, and the wireless charging module 16 is located at the one of the length direction of housing 11 Side, the radiating module 15 is located at the opposite side of the length direction of housing 11, when the electronic equipment for possessing wireless charging function When being attached at upper 11 surface of lid, the wireless charging module 16 can automatic sensing and for the electronic equipment charge.

The lower cover 14 is heat-conducting, for example, the thermal conductive metal plate and lower frame directly with side wall 13 is bonded on one Rise, the coil module 161 and circuit board 162 of wireless charging module 16 are directly anchored on lower cover 14, and its course of work is sent Heat shell be quickly transferred to lower cover 14, and the external world is dispersed into by lower cover 14.In other embodiments, the side wall 13 with The lower cover 14 can be one-time formed integrative-structure.

It should be appreciated that it is only one embodiment of the present invention that radiator structure is embodied as into heat emission hole 121,131, In other embodiment, according to actual design demand, radiator structure is it can also be provided that other structures, such as radiating groove etc., as long as Enable to the inside of charger shell 11 to have cross-ventilation with the external world, an induction coil 161 be only set in the present embodiment, In other embodiments, induction coil can be 2 or multiple, so as to be charged for multiple electronic equipments simultaneously.
