Abstract

The invention relates to a wireless charger and a wireless charging system. The wireless charger includes a casing, a magnetic shielding layer, a coil and an excitation layer arranged in the casing, the casing includes a top case and a base, and the top case and the base Support and cooperate to form an annular closed cavity for accommodating the coil and the excitation layer. The base has a base intermediate support part arranged at intervals along the horizontal direction inside and outside and a base annular support part on the periphery of the base intermediate support part. The annular closed cavity is arranged in the middle of the base Between the support portion and the base annular support portion, the top shell has a top shell intermediate support surface and a top shell annular support surface that respectively support and cooperate with the base intermediate support portion and the base annular support portion. The problems of low rolling resistance and high cost of the wireless charger in the prior art are solved.

Description
