[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0037] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0038] like Figures 1-6 As shown, this utility model provides a three-in-one magnetic wireless charger, including: a main module 1, with an air inlet 14 on the inner side of the main module 1 and air outlets 13 on both sides of the main module 1; a base module 2, which is hinged to the main module 1 via a pivot mechanism 7, and is used to support the main module 1 after it is rotated and unfolded; a wireless charging mechanism, which is disposed in the main module 1 and the base module 2, and includes a coil bracket, a magnet 32 disposed in the mounting cavity of the coil bracket, and a charging coil connected to the PCB control board disposed in the mounting cavity of the coil bracket; the wireless charging mechanism is divided into a mobile phone wireless charging unit 3, an earphone wireless charging unit 4, and a watch wireless charging unit 5, with the mobile phone wireless charging unit 3 disposed in the main module 1, and the earphone wireless charging unit 4 and the watch wireless charging unit 5 disposed in the base module 2; and a heat dissipation mechanism, which is disposed in the main module 1 and is used to dissipate heat when the wireless charging mechanism is used for charging.
[0039] The main module 1 and the base module 2 of this utility model provide support after being rotated and unfolded. The main module 1 magnetically attaches to wirelessly charge mobile phones, and the base module 2 is used to wirelessly charge earphones. The wireless charging unit 5 of the watch rotates and unfolds from the base module 2 to wirelessly charge the watch. Wireless charging generates heat, and high temperatures will affect charging efficiency and increase charging time. The heat dissipation mechanism is set inside the main module 1. When the main module 1 and the base module 2 are opened, they form a state of less than 90 degrees. The fan 6 inside the heat dissipation mechanism forms an air duct with the wireless charging unit 5 of the watch and the wireless charging unit 4 of the earphone. When the fan 6 works, it causes airflow and dissipates the heat from the coil and the charger.
[0040] Through its integrated design, the device enables wireless charging for three devices: mobile phones, earphones, and watches, greatly improving ease of use. Simultaneously, the heat dissipation mechanism effectively addresses potential overheating issues during wireless charging, ensuring charging efficiency and device safety. Furthermore, the main module 1 and base module 2 are hinged together via a pivot mechanism 7, allowing for flexible rotation and unfolding. This enables users to adjust the usage configuration according to their needs, further enhancing the user experience.
[0041] In some embodiments of this application, the main module 1 includes a main front cover 11 and a main back cover 12. An air outlet 13 is disposed on both sides of the main front cover 11, and an air inlet 14 is disposed on the main back cover 12. The mobile phone wireless charging unit 3 and the heat dissipation mechanism are disposed in the cavity formed between the main front cover 11 and the main back cover 12, and the mobile phone wireless charging unit 3 is disposed above the heat dissipation mechanism.
[0042] It is understandable that this embodiment effectively utilizes the internal space of the main module 1 to achieve an integrated design of wireless charging and heat dissipation for mobile phones. By placing the air outlet 13 on both sides of the main body cover 11 and the air inlet 14 on the main body back cover 12, an effective airflow path can be formed, improving heat dissipation efficiency. At the same time, the mobile phone wireless charging unit 3 is placed above the heat dissipation mechanism, which can ensure that the mobile phone receives sufficient heat dissipation protection during wireless charging, avoiding the impact of excessive temperature on charging efficiency and device safety.
[0043] In some embodiments of this application, the mobile phone wireless charging unit 3 includes a heat-conducting sheet 31, a heat-conducting adhesive 35, a mobile phone charging coil 33, a cooling sheet 36, and a mobile phone PCB control board 34 arranged sequentially from top to bottom. The mobile phone charging coil 33 is disposed in a mobile phone charging coil 33 bracket, and a magnet 32 is disposed around the mobile phone charging coil 33.
[0044] Understandably, the combined effect of the heat-conducting sheet 31, thermal adhesive 35, and cooling sheet 36 inside the wireless charging unit 3 can quickly conduct and dissipate the heat generated during charging, further improving the heat dissipation effect. The magnet 32 enhances the attraction between the phone and the wireless charging unit, ensuring the stability and safety of the phone during charging. Furthermore, the phone PCB control board 34, as the control core of the entire wireless charging unit, enables precise control of the charging process, ensuring charging efficiency and safety.
[0045] In some embodiments of this application, the heat dissipation mechanism includes a heat sink 61 and a fan 6; the heat sink 61 is disposed at the bottom of the cooling plate 36, the cooling plate 36 includes a cooling surface and a heating surface, the heat sink 61 is in contact with the heating surface of the cooling plate 36, and the cooling surface of the cooling plate 36 is in contact with the mobile phone charging coil 33; the fan 6 is disposed in the middle of the bottom of the heat sink 61.
[0046] Understandably, the combined use of heat sink 61 and fan 6 can further accelerate heat dissipation and improve heat dissipation efficiency. Heat sink 61 is tightly attached to the heating surface of cooling fin 36, enabling it to absorb the heat generated by cooling fin 36 in a timely manner and transfer the heat to the surrounding environment through its large-area heat dissipation structure. Simultaneously, the fan 6 generates forced convection, accelerating the airflow around heat sink 61, thereby removing more heat and making the heat dissipation effect even more significant.
[0047] The cooling element 36 is a PTC cooling element 36, with one side for cooling and the other side generating heat, and its operation is controlled by the PCB. The cooling side of the cooling element 36 is attached to the mobile phone charging coil 33, and is connected to the heat-conducting sheet 31 (which is attached to the mobile phone and has a heat-conducting function) through the thermal adhesive 35 (to increase the heat dissipation effect). The heating side of the cooling element 36 is attached to the heat sink 61 (which is made of metal or a material with good heat dissipation).
[0048] PCB (Printed Circuit Board) is an important electronic component. It serves as the support for electronic components and the carrier for the electrical interconnection of electronic components.
[0049] In some embodiments of this application, the rotating shaft mechanism 7 includes: a main shaft 71, a spring 72, a rotating shaft 73, and a limiting cover 74; springs 72 are installed on both sides of the main shaft 71, rotating shafts 73 are installed on both sides of the springs 72, and limiting covers 74 are installed on both sides of the rotating shafts 73; the outer side of the rotating shafts 73 is provided with concave and convex positions arranged in a ring around the axis, and the inner side of the limiting cover 74 is provided with concave and convex positions arranged in a ring around the axis; the rotating shafts 73 and the limiting cover 74 fix the springs 72 through the concave and convex positions; a wire threading position 75 is provided inside the main shaft 71 for the electronic wire to pass through.
[0050] In this embodiment, a spring 7272 is placed on the other side of the rotating shaft 73 to maintain the force between the main shaft 71 and the rotating shaft 73, and can also be opened; the spring 72 is fixed by a limiting cover 74. Through the connection of the rotating shaft module, the main body module 1 and the base module 2 can be rotated out and stored. The main body module 1 is connected and fixed to the base module 2 through the rotating shaft mechanism 7, and rotates around the axis of the rotating shaft mechanism 7. When the main body module 1 rotates, the force of the spring 72 of the elastic damping element generates resistance to cooperate with the main body module 1 to form an arbitrary angle of rotation and stop. The main shaft 71 is hollow inside and is used to insert electronic wires for the connection between circuit boards to realize electrical connection.
[0051] Understandably, the multi-angle adjustment function of the wireless charging device is achieved through the coordinated use of the main shaft 71, spring 72, rotating shaft 73, and limiting cover 74. The spring 72 allows the rotating shaft 73 to rotate freely within a certain range and remain stable at any position, meeting the user's charging needs at different angles. The concave and convex design on the rotating shaft 73 and limiting cover 74 not only enhances the structural stability but also allows the electronic wires to be neatly threaded into the wire insertion position 75, avoiding cable clutter and improving the cleanliness and aesthetics of the device.
[0052] In some embodiments of this application, the base module 2 includes a base front cover 21, a base rear cover 22, and a fixing frame 23; the base front cover 21 is disposed on the base rear cover 22, the fixing frame 23 is disposed on the base front cover 21, and the rotating shaft mechanism 7 is installed in the fixing frame 23 and connected to the main body module 1.
[0053] Understandably, the design of the base module 2 makes the entire three-in-one magnetic wireless charging structure more stable, while also facilitating the installation and fixation of the hinge mechanism 7. The cooperation between the base front cover 21 and the base rear cover 22 not only enhances the strength of the base but also provides a stable mounting base for the mounting bracket 23. The mounting bracket 23 further ensures that the hinge mechanism 7 can be firmly installed on the base and stably connected to the main module 1.
[0054] In some embodiments of this application, the earphone wireless charging unit 4 includes an earphone charging coil 41 and an earphone PCB control board 42 arranged sequentially from top to bottom, with the earphone charging coil 41 disposed within the earphone charging coil 41 bracket.
[0055] Understandably, this design of the earphone wireless charging unit 4 allows the earphone charging coil 41 to be tightly integrated with the earphone PCB control board 42, improving charging efficiency. The bracket for the earphone charging coil 41 not only provides stable support for the earphone charging coil 41 but also effectively protects the coil and extends its service life.
[0056] In some embodiments of this application, the watch wireless charging unit 5 includes, from top to bottom, a watch cover 51, a watch PCB control board 52, and a watch charging coil 53, with the watch charging coil 53 housed within a watch charging coil bracket 54. The base module 2 has a watch charging limiting hole 55 on its side away from the fixing frame 23, and the watch charging coil bracket 54 matches the watch charging limiting hole 55, and is hinged to the base module 2. The watch wireless charging unit 5 has magnetic positioning and wireless transmission functions.
[0057] Understandably, this design of the watch wireless charging unit 5 allows the watch cover 51, watch PCB control board 52, and watch charging coil 53 to form a compact and efficient charging structure. The combination of the watch charging coil bracket 54 and the base module 2 not only ensures the stability of the watch during charging but also achieves precise positioning through the watch charging limiting hole 55, further improving the convenience and safety of charging. The hinged design of the watch charging coil bracket 54 and the base module 2 allows the watch wireless charging unit 5 to flexibly adjust its angle during use, providing users with a more comfortable charging experience.
[0058] In use, the main body module and the base module are unfolded to serve as supports, and the watch wireless charging unit is rotated and unfolded from the base module. The main body module is magnetically attracted to the mobile phone to be charged to wirelessly charge the mobile phone. The earphone wireless charging unit on the base module wirelessly charges the earphone to be charged, and the watch wireless charging unit wirelessly charges the watch to be charged.
[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model.
