Description

Technical Field

[0001] This utility model relates to the field of wireless chargers, specifically an angle-adjustable multi-functional wireless charger. Background Technology

[0002] A wireless charger is a device that uses the principle of electromagnetic induction for charging, similar to a transformer. It involves placing a coil at both the transmitting and receiving ends. The transmitting coil emits electromagnetic signals under the influence of electricity, while the receiving coil receives these signals and converts them into electrical current, thus achieving wireless charging. Wireless charging technology is a special power supply method that eliminates the need for power cords. It relies on electromagnetic waves to propagate and convert electromagnetic energy into electrical energy, ultimately achieving wireless charging.

[0003] Existing wireless chargers are limited in the range of electronic products they can charge. Their simple design supports too few electronic products. If multiple portable electronic devices need to be charged simultaneously, multiple chargers are required, which is both limiting and inconvenient. Therefore, those skilled in the art have provided an angle-adjustable multi-functional wireless charger to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a multi-functional wireless charger with an adjustable angle to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an angle-adjustable multifunctional wireless charger, comprising a vacuum base, a mounting base rotatably connected to the top of the vacuum base, a circuit board fixedly connected to the bottom inner wall of the mounting base, a main control chip mounted on the top of the circuit board, two batteries symmetrically fixedly connected to the top of the circuit board, and the two batteries being electrically connected to each other, one of the batteries having two charging ports on one side, the two charging ports passing through the mounting base and extending outside the mounting base, a sealing seat fixedly connected to the top of the mounting base, a second magnetic charging plate fixedly embedded in the bottom inner wall of the sealing seat, a ring fixedly connected to the top of the sealing seat, a first damping shaft rotatably connected to the bottom inner wall of the sealing seat, a support plate fixedly connected to the outer wall of the first damping shaft, a second damping shaft rotatably connected to the top of the support plate, a top cover fixedly connected to the outer wall of the second damping shaft, a first magnetic charging plate fixedly embedded in the top of the top cover, and a rod-shaped magnetic charger fixedly connected to the bottom of the top cover.

[0007] As a further improvement of this utility model: two rectangular magnetic charging disks are symmetrically fixedly embedded in the bottom inner wall of the sealing seat, and the two rectangular magnetic charging disks are respectively located on both sides of the second magnetic charging disk.

[0008] As a further embodiment of this utility model: the main control chip and the storage battery are electrically connected, and the storage battery is electrically connected to the rectangular magnetic charging disk, the second magnetic charging disk, the first magnetic charging disk, and the rod-shaped magnetic charger.

[0009] As a further embodiment of this utility model: the bottom of the top cover and the top of the ring are fitted together, and the top of the mounting base and the bottom of the sealing base are sealed together.

Pulling the first magnetic charging pad up will cause the first damping shaft to rotate. The rotation of the first damping shaft will cause the support plate to flip. At this time, the first magnetic charging pad will flip to the top of the ring via the second damping shaft. Bluetooth headphones can be placed on the second magnetic charging pad located below the top cover for charging. The rectangular magnetic charging pads on both sides can be placed on other small electronic products for charging. When the top cover flips to a vertical position via the second damping shaft, the rod-shaped magnetic charger can become a horizontal position. At this time, an electronic watch can be hung on the rod-shaped magnetic charger for charging.

[0014] This utility model is simple to use. The first magnetic charging pad can be used to charge mobile phones. The second magnetic charging pad and two rectangular magnetic charging pads can charge Bluetooth headsets and other small electronic products respectively. The rod-shaped magnetic charger can hang electronic watches to charge them.
