Embodiments of the invention

Before the embodiments are described in detail, it is understood that the invention is not limited to the details The invention may be embodied in other ways. Also, it will be understood that the phraseology and terminology used herein are for the purpose of description The words "including", "comprising", "having", and <RTIgt; </ RTI> <RTIgt; </ RTI> used herein are meant to include the items listed thereafter, their equivalents, and other additional items. In particular, when describing "a certain element", the invention does not limit the number of the elements to one, and may include a plurality.

In order to solve the problem of low charging efficiency caused by heat generation during wireless charging, those skilled in the art usually perform all possible means to dissipate heat from the wireless charging device. However, simply dissipating heat to the wireless charging device still does not solve the problem of low charging efficiency caused by heat generation. Through continuous experimentation and analysis, the applicant found that the heating problem of smart devices such as mobile phones during wireless charging is the biggest cause of low charging efficiency.

Based on the above findings, the present invention provides a wireless charger 99. Referring also to FIGS. 1 and 2, the wireless charger 99 is an in-vehicle wireless charger that charges an electronic device. The electronic device can be a mobile phone, a tablet, or the like. The wireless charger 99 includes a housing 10, a clamping member 20, a fixing member 30, a coil module 40, and a circuit board 50.

The housing 10 has a substantially rectangular parallelepiped shape including a front cover 12 and a rear cover 14 that are symmetrically disposed.

Therefore, the front cover 12 and the rear cover 14 are both semi-closed cavities, and the front cover 12 and the rear cover 14 cooperate with each other to form the rectangular body casing 10.

The housing 10 includes a front panel 120, a rear panel 140, a bottom panel 15, a top panel 16, a first side panel 17, and a second side panel 18. The front panel 120 and the rear panel 140 are disposed in parallel, and the front panel 120 is disposed at the bottom of the cavity of the second cover 22, and the rear panel 140 is disposed at the bottom of the cavity of the second body 21. The bottom plate 15 and the top plate 16 are arranged in parallel. The first side wall 17 and the second side wall 18 are arranged in parallel. The bottom plate 15, the first side wall 17, the top plate 16 and the second side wall 18 are vertically connected end to end to form a side wall connected between the front panel 120 and the rear panel 140.

The clamping member 20 fixes the electronic device to the housing 10, which includes a first clamping portion 31, a second clamping portion 32 and a support portion 33. The first clamping portion 31 and the second clamping portion 32 are symmetrically disposed on opposite sides of the housing 10, and protrude from the first side wall 17 and the second side wall 18 respectively from the housing 10 to clamp the electronic device The first clamping portion 31 and the second clamping portion 32 are held. The support portion 33 projects from the bottom plate 15 of the housing 10 and is supported at the bottom of the electronic device. The support portion 33, the first clamping portion 31 and the second clamping portion 33 cooperate to fix the electronic device to the housing 10, and the housing back cover of the electronic device rests on the front panel 120 of the housing 10. .
