Abstract

The invention is applicable to the technical field of wireless charging, and provides a wireless charger, comprising a negative pressure generator, a wireless charging module arranged above the negative pressure generator, a suction cup arranged above the wireless charging module, and a hollow shaft. One end of the hollow shaft is communicated with the suction disk after passing through the wireless charging module, and the other end of the hollow shaft is communicated with the negative pressure generator, which can generate negative pressure to make the suction disk adsorb the adsorbed object. The wireless charger of the invention adopts a negative pressure generator and a suction cup to adsorb the adsorbed object for wireless charging, or only acts as a support, which is more convenientand time-saving than the mechanical clamping of the absorbed object, and avoids the serious problem of heat generation caused by the increase of eddy current loss and greatly increases the market competitiveness of the product compared with the magnetic adsorption of the absorbed object.

Description

technical field [0001] The invention belongs to the technical field of wireless charging, in particular to a wireless charger. Background technique [0002] Most of the mobile phone wireless chargers for cars on the market need to use mechanical clamping to fix the mobile phone, which is not convenient to take and put, or takes a certain amount of time to take and put. And some products cannot realize the arbitrary orientation placement of mobile phone. At present, the magnet and the iron sheet can be placed in any orientation to absorb the mobile phone, but the magnet and the iron sheet are near the wireless charging module, which undoubtedly increases the eddy current loss of the entire system, resulting in serious heating of the wireless charger. Contents of the invention [0003] The purpose of the present invention is to provide a wireless charger, aiming to solve the technical problem that the existing wireless charger will cause serious heat generation when the mag...
