Detailed Implementation

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] This utility model embodiment provides a magnetic wireless charging device, such as... Figure 1 and Figure 2 As shown, the magnetic wireless charging device includes a base 1 and a magnetic wireless charging head 2. The base 1 has an upper top surface 121, and the magnetic wireless charging head 2 is fixedly mounted on the upper top surface 121. The end of the magnetic wireless charging head 2 away from the upper top surface 121 has a charging surface 25. A magnetic wireless charging module 421 is disposed within the magnetic wireless charging head 2, and the magnetic wireless charging module 421 is positioned close to the charging surface 25. The charging surface 25 is inclined relative to the upper top surface 121, and in the direction from the lower edge to the upper edge of the charging surface 25, the charging surface 25 is inclined towards the upper top surface 121.

[0028] This invention relates to a magnetic wireless charging device with a magnetic wireless charging head 2 mounted on the top surface 121 of a base 1. The end of the magnetic wireless charging head 2 furthest from the top surface 121 has a charging surface 25, which is inclined relative to the top surface 121. The charging surface 25 is tilted towards the top surface 121 from its lower edge to its upper edge, allowing it to face the user while tilting. This facilitates wireless charging by placing the phone against the charging surface 25 for magnetic attachment. During charging, the phone remains tilted and upright, with the screen always facing the user, allowing for easy viewing. Furthermore, compared to a support plate with a lower support portion, this invention allows the phone to be directly magnetically attached to the charging surface 25 of the magnetic wireless charging head 2 furthest from the top surface 121. Wireless charging is achieved with the combined support of the base 1 and the magnetic wireless charging head 2. The overall structure is simple, eliminating the need to consider the thickness or width of the phone for the support portion, thus ensuring compatibility with phones of different widths and thicknesses.

[0029] Specifically, such as Figure 2 As shown, the axis L of the magnetic wireless charging head 2 forms an angle with the upper surface 121, and the angle θ is an acute angle. This design, by setting the axis of the magnetic wireless charging head 2 at an acute angle with the upper surface 121, naturally creates an inclined surface on the charging surface 25. When the phone is magnetically fixed to the charging surface 25, it is tilted with the screen facing the user, making it easier for the user to view the phone. Users can directly view the screen without picking up the phone, facilitating video calls, watching videos, or viewing notifications, significantly improving the user experience.

[0030] Furthermore, such as Figures 3 to 5 As shown, a positioning mounting groove 1211 is provided on the top surface 121, and a positioning protrusion 22 is provided on the magnetic wireless charging head 2, which is inserted into the positioning mounting groove 1211. The cooperation between the positioning mounting groove 1211 and the positioning protrusion 22 ensures that the magnetic wireless charging head 2 is accurately positioned on the top surface 121 of the base 1. Precise positioning prevents the magnetic wireless charging head 2 from shifting or shaking during use, keeping the charging head at a stable tilt angle and position, providing a stable charging environment for the mobile phone. The way the positioning protrusion 22 is inserted into the positioning mounting groove 1211 also more firmly fixes the magnetic wireless charging head 2, avoiding loosening problems caused by long-term use or frequent placement of the mobile phone. Furthermore, the design of the positioning protrusion 22 and the positioning mounting groove 1211 makes the installation of the magnetic wireless charging head 2 simple and quick. During production assembly, installation can be completed simply by aligning the positioning protrusion 22 with the positioning mounting groove 1211 and inserting it, without the need for complicated alignment and fixing processes, saving assembly time and labor costs.

[0031] Specifically, the horizontal cross-section of the positioning mounting groove 1211 is triangular, and the shape of the positioning protrusion 22 corresponds to the shape of the positioning mounting groove 1211. The triangular positioning mounting groove 1211 and the corresponding positioning protrusion 22 cooperate. Due to the geometric characteristics of a triangle, after the positioning protrusion 22 is inserted into the positioning mounting groove 1211, it can effectively prevent the magnetic wireless charging head 2 from rotating on the base 1, ensuring that the magnetic wireless charging head 2 maintains a stable position and angle during use. Specifically, the horizontal cross-section of the positioning mounting groove 1211 is an isosceles triangle, and the shape of the positioning protrusion 22 corresponds to the shape of the positioning mounting groove 1211.

[0032] Furthermore, the positioning mounting groove 1211 is provided with three first through holes 12111, arranged in a triangular shape; the positioning protrusion 22 is provided with three first screw holes 221 corresponding to the three first through holes 12111, also arranged in a triangular shape; the first through holes 12111 and the first screw holes 221 are connected and fixed by screws, specifically, the screws pass through the first through holes 12111 and are screwed into the first screw holes 221. The triangular arrangement of the three first through holes 12111 and the first screw holes 221 utilizes the geometric stability of a triangle. When subjected to force, the triangular structure can evenly distribute stress, avoiding excessive local stress that could lead to structural deformation or damage, making the connection between the magnetic wireless charging head 2 and the base 1 more stable and able to withstand greater external forces. Moreover, the connection method of the three first screw holes 221 provides multiple fixing points, which, compared to single-point or double-point fixing, can more effectively prevent the magnetic wireless charging head 2 from rotating, loosening, or shifting on the base 1. This ensures the stability and reliability of the device during long-term use.

[0033] The base 1 includes a bottom shell 11 and a top cover 12. In one embodiment, the top cover 12 is fixed to the bottom shell 11 by adhesive or screws. Figure 6 As shown, a power interface 6 is also provided on the side of the bottom shell 11, which is electrically connected to the first circuit board 3. The power interface 6 is connected to a power source via a charging cable to power the magnetic wireless charging device. Specifically, the power interface 6 is a USB Type-C interface.

[0034] A first circuit board 3 is disposed within the base 1. A second through hole 12112 is provided in the positioning mounting groove 1211, and a third through hole 222 is provided on the positioning protrusion 22 corresponding to the second through hole 12112. The second through hole 12112 and the third through hole 222 are connected. The wires of the magnetic wireless charging head 2 are introduced into the base 1 through the second through hole 12112 and the third through hole 222 and electrically connected to the first circuit board 3. Introducing the wires (not shown) of the magnetic wireless charging head 2 into the base 1 through the second through hole 12112 and the third through hole 222 facilitates the routing of the wires and achieves concealed wiring, avoiding the mess caused by exposed wires and making the overall appearance of the device more concise and beautiful. The first circuit board 3 is a circuit distribution and control component of the magnetic wireless charging device, which can be implemented using conventional technical means in this field, and will not be described in detail here.

[0035] The positioning mounting groove 1211 has a fitting ring groove 1212 around its circumference, and the surface of the magnetic wireless charging head 2 around the positioning protrusion 22 fits into the fitting ring groove 1212. This design, where the surface of the magnetic wireless charging head 2 around the positioning protrusion 22 fits into the fitting ring groove 1212, makes the connection between the magnetic wireless charging head 2 and the base 1 tighter, creating a unified visual effect and improving the overall aesthetics of the product. It also makes the overall design of the magnetic wireless charging device more compact, which is beneficial for miniaturization.

[0036] like Figure 1 , Figure 6 and Figure 7 As shown, the top surface 121 has a charging position 1213, and a wireless charging module 4 is disposed in the base 1 corresponding to the charging position 1213; the charging position 1213 is arranged side by side with the magnetic wireless charging head 2. The charging position 1213 arranged side by side with the magnetic wireless charging head 2 can charge electronic devices such as headphones. The wireless charging module 4 is electrically connected to the first circuit board 3. The specific implementation of the wireless charging module 4 can adopt conventional technical means in this field, and will not be described in detail here.

[0037] like Figure 2 As shown, in the vertical projection direction, the lower edge of the charging surface 25 protrudes beyond the corresponding lower edge of the base 1. This protruding lower edge design of the charging surface 25 makes it more convenient for users to place or retrieve their phones. Users can easily lean their phones against the charging surface 25.

[0038] Furthermore, a counterweight metal block 5 is installed on the inner bottom wall of the base shell 11. The top cover 12 is connected to the counterweight metal block 5. Specifically, the top cover 12 is connected to the counterweight metal block 5 by screws, and the counterweight metal block 5 is installed on the inner bottom wall of the base shell 11 by screws. The installation of the counterweight metal block 5 on the inner bottom wall of the base shell 11 can significantly lower the center of gravity of the entire base 1. The low center of gravity design makes the base 1 more stable during placement and less prone to tipping over due to external forces. The weight of the metal block can increase the overall weight of the base 1, thereby improving the stability of the phone's adsorption. At the same time, the installation of the metal block can enhance the structural rigidity of the base 1 and reduce the deformation of the base 1 when subjected to external forces.

[0039] like Figure 3 As shown, the magnetic wireless charging module 421 includes a mounting base 211, a wireless charging coil 212, and multiple magnets 213. The wireless charging coil 212 is bonded to the mounting base 211, and the multiple magnets 213 are bonded to the mounting base 211 around the wireless charging coil 212. Multiple support ribs 23 are provided on the side wall near the charging surface 25 inside the magnetic wireless charging head 2, and the mounting base 211 is bonded to the support ribs 23 for fixation. The cover 12 of the magnetic wireless charging module 421 has a panel 24 forming the charging surface 25, which covers the magnetic wireless charging module 421. The panel 24 can be fixed to the magnetic wireless charging head 2 by screws, glue, or clips; these are all conventional fixing methods in the art and will not be described in detail here. The wireless charging module 4 can be bonded to the first circuit board 3 using double-sided adhesive.
