Abstract

The invention discloses a wireless charging coil aligning mechanism, belonging to the technical field of wireless power transmission. The wireless charging coil aligning mechanism comprises a secondary side coil protection shell, a primary side coil protection shell, an X-direction driving mechanism, a Y-direction driving mechanism, a Z-direction lifting mechanism, a connecting bracket, a base and electric control and sensor assemblies, wherein the X-direction driving mechanism, the Y-direction driving mechanism, the Z-direction lifting mechanism and the sensor and electric control assemblies constitute a mobile resistance device with spatial three degrees of freedom; and a square shell and a special-shaped support plate constitute the primary side coil protection shell. The wireless charging coil aligning mechanism disclosed by the invention overcomes the defect that primary and secondary side coils of a traditional wireless charging device for an electric vehicle can not be automatically aligned; automatic aligning of the primary and secondary side coils when the vehicle is parked is realized through the mobile structure with three degrees of freedom; and meanwhile, by designing the special-shaped support plate with a special shape, the pressure-resisting degree of the primary side coil is improved so as to prevent the primary side coil from being crushed by vehicle tires. The wireless charging coil aligning mechanism disclosed by the invention can better adapt to the working condition of the electric vehicle for wireless charging.

Description

technical field [0001] The invention belongs to the field of wireless charging of electric vehicles, in particular to a wireless charging coil alignment mechanism for three-degree-of-freedom movement in space formed by an X-direction driving mechanism, a Y-direction driving mechanism, a Z-direction lifting mechanism, sensors and electronic control components. Background technique [0002] In recent years, with the continuous development of power electronics technology, the efficiency and power of wireless charging systems have been continuously improved, and the application range has been continuously expanded. One of the main applications of wireless charging at present is the field of electric vehicles. Due to the bottleneck of battery technology, compared with internal combustion engine vehicles, electric vehicles have problems that cannot be solved in the short term, such as short battery life and high cost. Using wireless charging technology can avoid the technical pro...
