[0023] Reference Figure 1-4 The image shown is a preferred embodiment of the present invention.

[0024] A wireless charging dock for mobile phones includes a base 100, on which a wireless charging head 300 is provided for fixing a mobile phone and wirelessly charging the mobile phone. The wireless charging head 300 is located above the base 100 and is rotatably connected to the base 100. During the rotation of the wireless charging head 300 relative to the base 100, the center of gravity of the wireless charging head 300 remains unchanged.

[0025] The base 100 can be placed directly on a table or other surface to provide support. The wireless charging head 300 has a charging coil inside. When the charging coil is energized, it generates a changing magnetic field. When the phone is fixed on the wireless charging head 300, the magnetic field acts on the induction coil inside the phone to achieve wireless charging.

[0026] The mobile phone can be fixed to the wireless charging head 300 in various ways, and rotates with the wireless charging head 300, thereby changing the orientation of the mobile phone display.

[0027] The aforementioned wireless charging dock allows a mobile phone to be fixed on the wireless charging head 300 for wireless charging. The wireless charging head 300 can rotate relative to the base 100, synchronously rotating the mobile phone while maintaining the center of gravity of the wireless charging head 300. The mobile phone is fixed on the wireless charging head 300, and the rotation of the wireless charging head 300 reduces the torque generated by the mobile phone relative to the base 100, maintaining the stability of the base 100. There is no need for internal counterweights in the base 100, reducing the weight of the wireless charging dock, simplifying the structure, and lowering costs.

[0028] In this embodiment, the base 100 extends upward with a mounting arm 200, and the wireless charging head 300 is rotatably connected to the mounting arm 200. The wireless charging head 300 is suspended above the base 100. By arranging the mounting arm 200, it is convenient to install the wireless charging head 300, and the wireless charging head 300 can be arranged in a suspended manner above the base 100.

[0029] In this embodiment, the base 100 extends upward with two of the above-mentioned mounting arms 200, and there is a central gap region 201 between the two mounting arms 200. The wireless charging head 300 is placed in the central gap region 201, and the two sides of the wireless charging head 300 are rotatably connected to the mounting arms 200 respectively.

[0030] By forming two mounting arms 200, the two sides of the wireless charging head 300 are rotatably connected to the two mounting arms 200 respectively, which facilitates the rotational installation of the wireless charging head 300 and maintains the stability of the wireless charging head 300.

[0031] In this embodiment, the wireless charging head 300 has an adsorption surface 301 for adsorbing a mobile phone to fix the mobile phone and the wireless charging head 300 relative to each other, and the wireless charging head 300 has a magnetic block inside. The wireless charging head 300 uses a magnetic method to fix the mobile phone on the adsorption surface 301, which has a simple structure and facilitates the relative fixation between the mobile phone and the wireless charging head 300. Alternatively, a clamping method can also be used to fix the mobile phone relative to the adsorption surface 301.

[0032] In this embodiment, the adsorption surface 301 is flat and formed on the top of the wireless charging head 300, while the bottom of the wireless charging head 300 is spherical. This facilitates the upward orientation of the adsorption surface 301 and makes it easier for the mobile phone to be adsorbed onto the adsorption surface 301. The spherical bottom of the wireless charging head 300 prevents interference between the wireless charging head 300 and the base 100 during rotation.

[0033] In this embodiment, a shaft 302 protrudes from the side of the wireless charging head 300, and a recessed hole 202 is provided in the mounting arm 200. The shaft 302 is movably inserted into the recessed hole 202, so that the wireless charging head 300 and the mounting arm 200 are rotatably connected. Of course, the recessed hole 202 can also be provided on the side of the wireless charging head 300, and the shaft 302 can be provided on the mounting arm 200, as long as a rotatable connection between the wireless charging head 300 and the mounting arm 200 can be achieved.

[0034] In this embodiment, a limiting structure is provided between the recessed hole 202 and the shaft 302 to limit the rotation range of the wireless charging head 300. In this way, when the mobile phone is fixed on the wireless charging head 300, the orientation of the mobile phone's display surface can be adjusted within a limited range as the wireless charging head 300 rotates within a limited range.

[0035] In this embodiment, the limiting structure includes an arc-shaped notch 303 disposed on the shaft 302 and a protrusion 203 formed in the recessed hole 202. The arc-shaped notch 303 is arranged in a circumferential arc shape along the shaft 302, and the protrusion 203 is placed in the arc-shaped notch 303. When the protrusion 203 abuts against the end of the arc-shaped notch 303, the wireless charging head 300 rotates to the limit position.

[0036] As the wireless charging head 300 rotates, the protrusion 203 moves within the arc-shaped notch 303. When the protrusion 203 abuts against the end of the arc-shaped notch 303, the wireless charging head 300 rotates to its limit position.

[0037] In this embodiment, the base 100 is provided with a wireless charging pad 101 for wristbands that is housed in the base 100 or extends outside the base 100. When a wristband needs to be wirelessly charged, such as a watch, the wireless charging pad 101 can be extended outside the base 100, and the wristband can be placed on the wireless charging pad 101 for wireless charging.

[0038] In this embodiment, the seat 100 is provided with a wireless charging pad 102 for headphones that is housed in the seat 100 or extends outside the seat 100. The wireless charging pad 102 for headphones is provided with a recessed position 103 for placing headphones. The wireless charging pad 102 for headphones extends away from the wireless charging pad 101 for wristbands.

[0039] The earphones can be wirelessly charged by placing them directly on the recessed position 103. Furthermore, the earphone wireless charging pad 102 and the wristband wireless charging pad 101 are arranged opposite to each other, which facilitates the structural layout.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
