Description

Technical Field

[0001] The utility model belongs to the technical field of magnet units, and in particular relates to a magnet unit for a wireless charging receiving end that can be accurately positioned and installed. Background Art

[0002] The wireless charging receiver is a core component of the wireless charging system and works mainly based on the principle of electromagnetic induction. When the wireless charging transmitter is powered on, the generated current forms a changing magnetic field in the transmitting coil. This magnetic field is transmitted through the air to the receiving end and induces a current in the receiving coil. This current then passes through a rectifier circuit to convert the AC power into DC power and is stored in the battery or energy storage device at the receiving end for use by the device. The difference between the wireless charging receiver and the transmitter is mainly the direction of energy transfer. The transmitting coil is mainly responsible for transferring the energy, while the receiving end is responsible for receiving the energy. This wireless charging method provides a convenient and efficient way to charge smart devices.

[0003] There is a group of magnet units inside the wireless charging receiver, which are adsorbed and connected with the transmitting device during the charging process. However, a considerable impact force will be generated between the two during adsorption. Since the wireless charging receiver is designed to be used for a long period of time, this adsorption impact phenomenon will occur repeatedly. Frequent impact may not only cause the magnet unit to loosen, but is more likely to damage the magnet inside the magnet unit. In view of this, we urgently need to improve the magnet unit of the wireless charging receiver to reduce the adverse effects of impact and ensure the stability and safety of wireless charging.
