[0036] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0037] Example 1, please refer to Figures 1-6 , the double-sided magnetic adsorption wireless charger, includes: a bottom shell 100 and a middle shell 200; the middle shell 200 is detachably arranged above the bottom shell 100, an internal magnet 500 is arranged inside the middle shell 200, a charging induction coil 400 is also arranged inside the middle shell 200, and a bottom magnet 103 is arranged in the middle of the lower part of the bottom shell 100; through the internal magnet 500 arranged in this application, a mobile phone can be adsorbed; and the bottom magnet 103 arranged can adsorb this double-sided magnetic adsorption wireless charger onto a ferromagnetic object for use, which can be applicable to more scenarios, is relatively convenient to use and fix, greatly expands the usage scenarios, and this application does not need to use an additional fixing rack or bolt, greatly improving the convenience of use;

[0038] The internal magnet 500 attracts with the magnet on the device to be charged, realizing quick alignment and stable connection, improving the charging efficiency. The internal magnet 500 is arranged in a circular ring shape and can also be set into different shapes according to usage needs. The charging induction coil 400 is responsible for generating a magnetic field and interacting with the receiving coil inside the device to be charged to realize wireless charging.

[0039] Further, as Figure 5 shown, it further includes a circuit board 300. The circuit board 300 is disposed between the bottom case 100 and the middle case 200. The circuit board 300 is the core control component of the wireless charger and is responsible for functions such as charging control.

[0040] Example 2 further optimizes the double-sided magnetic adsorption wireless charger provided in Example 1. Specifically, as Figure 2 shown, a panel 201 is provided at the upper end of the middle case 200, and the panel 201 covers the charging induction coil 400 and the internal magnet 500. As the part where the user directly contacts the charger, the panel 201 can be aesthetically designed or functionally expanded according to needs, meeting the user's requirements for the product appearance, increasing the product's attractiveness. In today's market environment that emphasizes product appearance design, a beautiful charger is more likely to be favored by users. Secondly, functional expansion can provide more convenience for users, such as expanding anti-slip, anti-scratch and other functions, which can be achieved by coating existing coatings; at the same time, the coverage of the panel 201 also plays a role in protecting the charging induction coil 400 and the internal magnet 500, extending the service life of the charger.

[0041] Further, as Figure 5 shown, a notch 101 is provided on the side of the bottom case 100, and a charging female socket 102 is provided in the notch 101. The tail of the charging female socket 102 is connected to the circuit board 300. The connection between the tail of the charging female socket 102 and the circuit board 300 can be made by welding.

[0044] Example 3 further optimizes the double-sided magnetic adsorption wireless charger provided in Example 1 or 2. Specifically, asFigure 5 As shown in the figure, multiple internal threaded hole mounting posts 104 are provided at the bottom inside the bottom case 100. The middle case 200 and the circuit board 300 are threadedly connected through bolts and the internal threaded hole mounting posts 104. This setting makes the connection firm and reliable, ensuring that the middle case 200 and the circuit board 300 will not loosen during use, guaranteeing the overall stability of the charger. Secondly, this connection method is convenient for assembly and disassembly. When maintenance or component replacement is required, users can easily operate, reducing the maintenance cost. At the same time, the threaded connection method also has a certain anti-seismic performance and can maintain the connection stability when subjected to external vibrations.

[0045] Further, as Figure 4 and Figure 5 shown, a lower mounting groove 105 penetrating to the inside of the bottom case 100 is provided at the bottom of the bottom case 100. The bottom magnet 103 is arranged in the lower mounting groove 105. The limitation of the lower mounting groove 105 on the bottom magnet 103 prevents the bottom magnet 103 from moving randomly during use, ensuring the stability of adsorbing iron objects.

[0046] Further, as Figure 4 shown, a baffle 106 is provided at the lower part of the lower mounting groove 105. The baffle 106 is used to limit the bottom magnet 103 to prevent the bottom magnet 103 from sliding out of the lower mounting groove 105. The upper end of the bottom magnet 103 abuts against the lower end of the circuit board 300.

[0047] Further, as Figure 6 shown, a connection groove 107 is provided at the upper end of the bottom case 100. A connecting plate 108 is provided at the lower end of the middle case 200. The middle case 200 is connected and matched with the connection groove 107 through the connecting plate 108, realizing the stable connection between the middle case 200 and the bottom case 100, and improving the overall stability and durability of the charger.

[0048] During use, insert the type-c charging plug of the charging cable into the charging female socket 102. For iron objects, this charger can be adsorbed on the iron object through the bottom magnet 103. For example, it can be adsorbed on fitness equipment, etc. On the one hand, it can be conveniently fixed. Then place the mobile phone on the panel 201, and the mobile phone will be adsorbed on the charger, and then charging can be carried out. When exercising, videos can be watched or data can be observed, etc. It should be noted that the magnetic adsorption design adopted in this application enables this application to be fixed to any iron object, expanding the usage scenarios.
