Problems solved by technology
[0005] The current mainstream on-board wireless charging solutions basically conform to the Qi standard. Therefore, the corresponding on-board wireless charging device uses three Litz (Litz) coils in a row for charging, so that the effective charging area provided by it is enlarged to suit Charging of smartphones; however, the layout of the effective charging area of the Litz coil is easily restricted, the design flexibility of the effective charging area is poor, and it is not suitable for electronic products with relatively small charging power (such as various wearable smart terminals) Charge

The invention relates to a vehicle-mounted wireless charging device and a vehicle-mounted armrest box using the vehicle-mounted wireless charging device, and belongs to the technical field of wirelesscharging. The vehicle-mounted wireless charging device is used for wirelessly charging an electronic product and comprises a plurality of primary coils used for providing inductive energy to the electronic product. The vehicle-mounted wireless charging device is characterized in that a plurality of primary coils include a first coil and a second coil which is formed on a printed circuit board. The second coil provides lower charging power relative to the first coil, and the second coil is arranged at a different position relative to the first coil so that the first coil and the second coil are respectively suitable for providing the inductive energy to the electronic product with different charging power requirements and sizes. The wireless charging area of the vehicle-mounted wireless charging device has good design flexibility and can simultaneously meet the wireless charging requirements of various types of electronic products with different powers and sizes so as to have good vehicle-mounted wireless charging experience.
Description
technical field [0001] The invention belongs to the technical field of wireless charging, and relates to a vehicle-mounted wireless charging device. Background technique [0002] With the wide application of mobile phones, smart watches, etc. as consumer electronic products, there are more and more charging demands for consumer electronic products. For example, consumers have charging demands for various consumer electronic products when riding in vehicles. [0003] At present, consumers are no longer satisfied with charging various electronic products or electronic products such as mobile phones by relying on the wired charging method of connecting the wiring harness, and hope to use wireless charging (WirelessPower Transfer, WPT) which is more convenient and has a better experience. Therefore, for example, vehicles are generally equipped with on-board wireless charging devices to charge electronic products such as mobile phones. [0004] However, electronic products are d...
