Description

Technical Field

[0001] This utility model relates to a vehicle-mounted wireless charger. Background Technology

[0002] Chinese patent document CN222915728U discloses a vehicle-mounted wireless charger with a heat dissipation structure, relating to the field of vehicle-mounted charger technology. It includes a front housing, an NFC antenna, a bracket, a coil, a printed circuit board assembly, a rear housing, an outer air duct housing, a fan, and a fan housing. The outer air duct housing is located above the rear housing, and the fan is mounted on the fan housing, which is connected to the outer air duct housing. The front housing has an air outlet, and the rear housing has a diverter plate. The diverter plate splits the air output from the fan into two ventilation channels, one for cooling the charging device and the other for cooling the charger. While the above-described vehicle-mounted wireless charger has good heat dissipation and cooling effects, it is not conducive to stable alignment and charging of the phone and charger, especially in poor road conditions where the phone may shift, leading to charging failure. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a vehicle-mounted wireless charger that can provide stable charging.

[0004] Another objective of this invention is to provide a car storage rack equipped with a wireless charging pad.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A vehicle-mounted wireless charger includes a housing, characterized in that it further includes a wireless charging module and a magnetic module. The housing includes a first top plate, a first side plate, a bottom plate, and a charging platform. The bottom plate is arranged parallel to and opposite to the first top plate. The first side plate is connected between the first top plate and the bottom plate. The charging platform protrudes from the first top plate and includes a second top plate and a second side plate. The second side plate is connected between the second top plate and the first top plate. The wireless charging module includes a charging coil and a driving circuit. The charging coil is disposed in the charging platform. The driving circuit is connected to the charging coil to supply power to the charging pad. The magnetic module includes a plurality of magnets arranged circumferentially. The plurality of magnets are adapted to be disposed in the charging platform and surround the outside of the charging coil.

[0007] In the above solution, the magnetic module firmly and stably attaches the phone to the charging platform, achieving accurate positioning of the phone. The drive circuit drives the charging coil to wirelessly charge the phone, thereby ensuring the stability of the phone charging, preventing the phone from shifting and affecting the charging effect. In addition, the charging platform can also partially suspend the phone, thereby improving the phone's heat dissipation performance.

[0008] The bottom of the second top plate has an annular groove, in which multiple magnets are embedded. This structure facilitates the positioning and installation of the magnets.

[0009] The wireless charging module also includes a substrate, and the charging coil is fixedly disposed on the top surface of the substrate, which is basically parallel to the second top plate. This structure facilitates the stable installation of the charging coil.

[0010] It also includes a circuit board disposed in the housing for carrying the drive circuit.

[0011] It also includes a Type-C interface for connecting the drive circuit. The first top plate is provided with a clearance hole adapted to the Type-C interface, so that in addition to wireless charging, wired charging can also be performed through the Type-C interface.

[0012] The magnetic module also includes an annular mounting plate, and a plurality of magnets are fixedly mounted on the top surface of the annular mounting plate. The annular mounting plate is arranged parallel to the second top plate, and this structure facilitates the assembly of the magnets.

[0013] The first top plate and the first side plate are integrally injection molded, and the bottom plate is a metal plate with a heat dissipation structure, which can improve heat dissipation performance.

[0014] A sealing ring is provided between the lower edge of the first side plate and the bottom plate.

[0015] The second top plate is circular, and the second side plate is circular. The outer edge of the second top plate is spaced apart from the second side plate and is bridged to the inner wall of the second side plate through multiple connecting parts. This structure can form heat dissipation holes on the top of the charging platform, thereby improving heat dissipation performance.

[0016] A car storage rack, fixedly installed inside a car compartment, is characterized by comprising a rack body and a car-mounted wireless charger. The top surface of the rack body has at least one storage groove and a charging groove. The bottom of the charging groove forms a mounting groove. The car-mounted wireless charger is installed in the mounting groove, with the top surface of the first top plate flush with the bottom of the charging groove. This structure can further improve the stable placement of mobile phones. Attached Figure Description
