In order to solve the problem of navigation viewing, part of the vehicle-mounted charging devices select to vertically fix the mobile phone near the windshield and position the mobile phone through a clamping mechanism. Although the design is convenient for navigation and viewing, the uneven clamping force can damage the mobile phone shell and the function keys due to the diversity of mobile phone sizes; in addition, the clamping mechanism is often designed at the side of the mobile phone, and is inevitably contacted with keys of the mobile phone during clamping, so that misoperation is caused; meanwhile, in the driving process, a driver holding the steering wheel may need to take down the mobile phone rapidly due to emergency, but the traditional clamping mechanism operated by two hands is laborious and cannot be taken down by one hand rapidly, and safety risks are caused during operation.

With the progress of smart phone camera technology, multi-camera and large-size lens modules have become standard of high-end mobile phones. These outstanding camera lens modules can make to place between cell-phone and the charging device on wireless charging module and produce the gap, have reduced electromagnetic coupling efficiency, and then influence charging efficiency.

In summary, the conventional mobile phone vehicle-mounted charging device has a plurality of technical defects in wireless charging. Therefore, it is necessary to invent a wireless charging device for a vehicle-mounted mobile phone to solve the above problems.
