Abstract

The invention discloses a vehicle-mounted wireless charging device. The vehicle-mounted wireless charging equipment comprises a shell, a wireless charging coil accommodated in the shell and an NFC antenna substrate, the NFC antenna substrate is arranged above the wireless charging coil, an electromagnetic shielding device is arranged on the NFC antenna substrate, the electromagnetic shielding device comprises a grid type shielding body formed by conductive printing traces, and the grid type shielding body is arranged above the wireless charging coil. The grating type shielding body is arranged to selectively filter out frequency multiplication harmonic waves of the working frequency of the wireless charging coil. According to the invention, electronic devices do not need to be added, interference noise can be effectively suppressed by using the NFC antenna substrate through a specific PCB design, the EMC performance is improved, and the product meets the requirements.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted electronic products, and more particularly relates to a vehicle-mounted wireless charging device integrated with an electromagnetic shield. Background technique [0002] In order to improve the performance and user comfort of automobiles, more and more electronic products are integrated in automobiles. In the automotive field, the Electromagnetic Compatibility (EMC) test for on-board electronic products is very strict. When multiple electronic devices are integrated together, there may be interference between them. Especially for wireless charging equipment, its operating frequency multiplier harmonic will radiate into the space through the charging coil, causing interference to other equipment, especially for 15W charging equipment, the energy exchange during normal operation has higher radiation energy. This interference will make the EMC test fail. Equipment suppliers have invested a...
