[0032] 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.
[0033] This utility model embodiment provides a wireless charging device, such as... Figure 1 and Figure 2As shown, the wireless charging device includes a wireless charging pad 1 and a charging cable 2. The wireless charging pad 1 includes a housing 11, a control circuit board 12, and a wireless charging module 13. A cable outlet 1111 is provided on the side of the housing 11. The control circuit board 12 and the wireless charging module 13 are installed inside the housing 11, and the wireless charging module 13 is electrically connected to the control circuit board 12. The electrical connection end 22 of the charging cable 2 is electrically connected to the control circuit board 12 and extends from the cable outlet 1111 to the outside of the housing 11. Inside the housing 11, a limiting slot 143 is provided at the cable outlet 1111, and a limiting block 21 is provided on the electrical connection end 22, with the limiting block 21 engaging in the limiting slot 143.
[0034] The wireless charging device of this utility model has a limiting block 21 on the electrical connection end 22 of the charging cable 2 and a limiting slot 143 at the cable outlet 1111 inside the housing. Through the locking cooperation of the limiting block and the limiting slot 143, the electrical connection end 22 of the charging cable 2 is limited and fixed. No matter whether the electrical connection end 22 is pulled outward or pushed inward, it can be limited by the cooperation of the limiting block and the limiting slot 143, so as to avoid the electrical connection end 22 of the charging cable 2 from being disconnected from the control circuit board 12 of the wireless charging panel and the problem of poor electrical connection. The wireless charging device is not easily damaged.
[0035] Specifically, the wireless charging module 13 can be a magnetic wireless charging module 13. The limiting block 21 can be integrally formed on the electrical connection end 22 of the charging cable 2.
[0036] Specifically, such as Figures 5 to 8 As shown, an inner support plate 14 is installed inside the wireless charging pad 1, surrounding the outer shell 11. The inner support plate 14 has a protruding edge 141 surrounding the outer shell 11. A surrounding edge 142 is provided at the cable outlet 1111 corresponding to the protruding edge 141, and the surrounding edge 142 forms a limiting groove 143. The inner support plate 14 provides stable support for the internal components of the wireless charging device, enhancing the structural stability of the entire device. At the same time, the limiting groove 143 formed by the surrounding edge 142 makes the structure of the limiting groove 143 more stable, further improving the stability of the charging cable 2 connection. The inner support plate 14 can be fastened to the inner side of the outer shell 11 by a buckle 144 provided on the outer side of the protruding edge 141.
[0037] The enclosure 142 is open on one side of the outlet 1111, and a first opening 1421 is provided on the other side. The electrical connection terminal 22 is electrically connected to the control circuit board 12 through the first opening 1421. In this way, the electrical connection terminal 22 can be easily connected to the control circuit board 12 through the first opening 1421, and can be led out from the outlet 1111 through the enclosure 142 being open on one side of the outlet 1111, while ensuring the integrity of the limiting slot 143. This facilitates assembly and ensures the stability of the charging cable 2 connection.
[0038] like Figure 4 , Figure 9 and Figure 10 As shown, the wireless charging module 13 includes a magnet holder 131 and multiple magnets 132. The magnet holder 131 is mounted on a protruding edge 141, and a magnet 132 mounting groove 1311 is provided around the edge of the magnet holder 131, in which the magnets 132 are installed. The magnet holder 131 and the magnets 132 are the core components of the wireless charging module 13. By installing the magnets 132 in the magnet 132 mounting groove 1311, the stable installation of the magnets 132 can be ensured, thereby guaranteeing the normal operation of the wireless charging module 13 and improving the efficiency and stability of wireless charging. Specifically, the magnets 132 can be glued to the magnet 132 mounting groove 1311.
[0039] A charging coil 133 is mounted on a magnet holder 131, and a magnet 132 is arranged around the charging coil 133. A wiring port 1312 is provided on the magnet holder 131 near the mounting slot 1311 of the magnet 132. The control circuit board 12 is mounted on the protruding edge 141 and located below the wireless charging module 13. The wires 1331 of the charging coil 133 pass through the wiring port 1312 and are electrically connected to the control circuit board 12. The arrangement of the magnet 132 around the charging coil 133 can enhance the magnetic field and improve the efficiency of wireless charging. The design of the wiring port 1312 allows the wires 1331 of the charging coil 133 to be easily connected to the control circuit board 12, while ensuring the neatness and aesthetics of the internal wiring layout.
[0040] Furthermore, on the side facing away from the magnet 132, a plurality of heat dissipation grooves 1313 are provided around the edge of the magnet holder 131. The heat dissipation grooves 1313 can effectively improve the heat dissipation performance of the wireless charging device, avoid the internal temperature of the device from becoming too high due to long-term operation, which may affect the charging efficiency or damage the wireless charging device, and extend the service life of the wireless charging device.
[0041] On the side facing away from the magnet 132, the edge of the magnet holder 131 is recessed with a limiting groove 1314 corresponding to the limiting block 21, and the limiting groove 1314 presses against the limiting block 21. The setting of the limiting groove 1314 further enhances the stability of the limiting block 21, making the connection between the charging cable 2 and the wireless charging device more secure, and further improving the charging stability. At the same time, the limiting groove 1314 can also avoid the limiting block 21, so as to achieve stable installation of the magnet holder 131. Specifically, the magnet holder 131 and the control circuit board 12 are both mounted on the inner support plate 14 with screws.
[0042] The control circuit board 12 has a clearance slot 121 on its edge corresponding to the enclosure edge 142. The clearance slot 121 is designed to allow the control circuit board 12 to better fit with the inner support plate 14, avoiding mutual interference between components and facilitating the assembly of the control circuit board 12.
[0043] An internal cavity 15 is provided between the bottom surface of the control circuit board 12 and the inner support plate 14. The outer casing 11 includes a bottom casing 111 and a front casing 112, with the front casing 112 covering the bottom casing 111. The cable outlet 1111 is located on the side of the bottom casing 111. The front casing 112 can be mounted on the bottom casing 111 by screws or adhesive, which will not be described in detail here.
[0044] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
