Description

Technical Field

[0001] This invention relates to the field of wireless charging for mobile electronic devices, specifically a rotating wireless charger. Background Technology

[0002] Wireless charging utilizes wireless charging technology to quickly charge mobile phone batteries. Its principle is based on electromagnetic induction. Wireless charging is convenient and avoids the slow charging speed caused by poor contact at the plug in wired charging. Current fast wireless chargers typically add a casing around the circuit board, which solves the problem of supporting the phone but also has the following drawbacks:

[0003] Current fast wireless charging typically involves placing the phone directly on top of the wireless charger. This makes it inconvenient for users to rotate the charger, impacting the user experience and making it difficult for them to use the device.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see Figures 1-17A rotating wireless charger includes, in sequence, an upper cover 1, a magnetic chuck 2, a wireless charging assembly 3, an insulating partition 4, a PCB board 6, and a lower cover 5. The insulating partition 4 has at least one wireless charging assembly mounting slot 41 and at least one magnetic chuck mounting slot 42. The wireless charging assembly 3 is installed in the wireless charging assembly mounting slot 41, and the magnetic chuck 2 is installed in the magnetic chuck mounting slot 42. The PCB board 6 is located on the lower cover 5 below the insulating partition 4, and the upper cover 1 is installed on the wireless charging assembly 3. The charger also includes an insulating block 7 and at least one set of positive and negative conductive metals B. The positive and negative conductive metals B are spaced and embedded around the insulating block 7 to form an island-shaped positive and negative conductive metal block X, which is located at the bottom of the insulating partition 4.

The device includes at least one set of positive and negative power supply contacts B1 for the wireless charging component. The positive and negative conductive contacts A of the wireless charging component pass through the insulating partition 4 and connect to the positive and negative power supply contacts B1. The positive and negative conductive metal B electrically connects to the positive and negative power supply contacts B1. A ring-shaped positive and negative conductive metal block X is located at the bottom of the insulating partition 4, and the positive and negative cylindrical conductive metal C on the PCB board 6 is connected to the ring-shaped positive and negative conductive metal block X via a movable friction mechanism. When the mobile electronic device is being wirelessly charged, the insulating partition 4 can achieve 360-degree rotation simply by sliding and rubbing the ring-shaped positive and negative conductive metal block X against the positive and negative cylindrical conductive metal C. This technical solution's rotating main structure only requires the simple combination of the insulating partition 4, the ring-shaped positive and negative conductive metal block X, and the positive and negative cylindrical conductive metal C to achieve 360-degree rotation.
