[0034] The present utility model provides a wireless charger. Figures 1 to 6 As shown, the wireless charger includes a wireless charging plate 3 , and the wireless charging plate 3 includes a shell 31 and a first wireless charging module 32 ; the first wireless charging module 32 is installed in the shell 31 .

[0035] The first wireless charging module 32 includes a main integrated disk 321, a coil 322, a coil tray 323, a circuit board 324 and a plurality of magnets 325; the circuit board 324 is mounted on the first side 321a of the main integrated disk 321, the coil tray 323 is mounted on the second side 321b of the main integrated disk 321 opposite to the first side 321a, the coil 322 is mounted on the coil tray 323, and both ends are led out from the coil tray 323 and connected to the circuit board 324; a plurality of magnets 325 are mounted on the second side 321b and arranged around the coil 322.

[0036] The utility model sets a main integrated disk 321, and installs the circuit board 324 on the first side 321a of the main integrated disk 321. The coil 322 is installed on the second side 321b of the main integrated disk 321 through the coil tray 323. The magnet 325 is also installed on the second side 321b. Based on the main integrated disk 321, the important components of the first wireless charging module 32 are integrated and modularized, so that the first wireless charging module 32 is easy to assemble into the wireless charger, and it is also more convenient to disassemble and repair.

[0037] Specifically, the first wireless charging module 32 can be bonded to the housing 31 or fixed to the housing 31 by screws through the main integrated disk 321.

The first limiting convex edge 321b1 is provided on the second side 321b to limit the limiting installation area 321b2, so that the coil tray 323 is limited and installed in the limiting installation area 321b2. Under the limitation of the first limiting convex edge 321b1, the installation of the coil tray 323 is firm. The coil tray 323 can be further bonded to the main integrated disk 321 by glue or the like. The first limiting convex edge 321b1 can surround the limiting installation area 321b2 into a circle. The first limiting protrusion 321b1 can be formed by continuously surrounding the limiting installation area 321b2, or can be formed by intermittently surrounding the limiting installation area 321b2. Fig.11As shown, the main integrated disk 321 also includes a mounting ring edge 321c, which is arranged around the circumference of the first limiting convex edge 321b1, and a second limiting convex edge 321e is arranged around the edge of the mounting ring edge 321c; the magnet 325 is installed between the first limiting convex edge 321b1 and the second limiting convex edge 321e. The first limiting convex edge 321b1 and the second limiting convex edge 321e respectively limit the magnet 325, which can further improve the installation stability of the magnet 325.

[0038] Furthermore, a groove 321c1 is provided on the second side surface 321b of the mounting ring edge 321c, and the magnet 325 is bonded to the second side surface 321b of the mounting ring edge 321c. The groove 321c1 can increase the friction force and the contact area, so that the magnet 325 can be more firmly bonded to the second side surface 321b of the mounting ring edge 321c.

[0039] The main integrated disk 321 is provided with a wire-passing opening 321d, and the two ends of the coil 322 are led out from the wire-passing opening 321d and connected to the circuit board 324. The provision of the wire-passing opening 321d facilitates the two ends of the coil 322 to be led out from the coil tray 323 and connected to the circuit board 324. A surrounding boss 323a is provided at the center of the coil tray 323, and the coil 322 is arranged around the surrounding boss 323a. The surrounding boss 323a can limit the coil 322, thereby improving the installation firmness of the coil 322.

[0040] Furthermore, a limiting column 321a1 and a buckle 321a2 are provided on the first side surface 321a, a limiting hole 324a is provided on the circuit board 324, the limiting column 321a1 is inserted into the limiting hole 324a, and the buckle 321a2 is buckled at the edge of the circuit board 324. In this solution, a limiting column 321a1 and a buckle 321a2 are provided on the first side surface 321a, wherein the limiting column 321a1 is engaged with the limiting hole 324a, and the buckle 321a2 is buckled at the edge of the circuit board 324, thereby achieving radial and axial limiting of the circuit board 324, and ensuring that the circuit board 324 is firmly fixed. Multiple buckles 321a2 and limiting columns 321a1 are provided, and multiple limiting holes 324a are also provided accordingly.

[0041] Furthermore, the wireless charger also includes a wireless charging base 1 and a support rod 2; a second wireless charging module 11 for wireless charging is arranged in the wireless charging base 1.

[0042] The two ends of the support rod 2 are rotatably connected to the wireless charging base 1 and the wireless charging plate 3, respectively, so that the wireless charging plate 3 can be folded and stored on the wireless charging base 1. When the wireless charging plate 3 is folded and stored on the wireless charging base 1, the wireless charging plate 3 covers the wireless charging base 1, and the support rod 2 is hidden and stored between the wireless charging base 1 and the wireless charging plate 3.

[0043] The wireless charging base 1 and the wireless charging plate 3 are rotatably connected via the support rod 2, so that the wireless charging plate 3 can be folded and stored on the wireless charging base 1. When the wireless charging plate 3 is folded and stored on the wireless charging base 1, the wireless charging plate 3 covers the wireless charging base 1, and the support rod 2 is hidden and stored between the wireless charging base 1 and the wireless charging plate 3. Figure 8 As shown, the foldable wireless charger can be folded and stored more efficiently, and the volume after folding and storage is smaller, and the overall shape is more regular, which is convenient for storage and carrying. At the same time, since the wireless charging plate 3 covers the wireless charging base 1 and the support rod 2 is hidden and stored between the wireless charging base 1 and the wireless charging plate 3, the foldable wireless charger is not easy to accumulate dust after folding and storage.

[0044] In addition, the foldable wireless charger of the present invention is provided with a first wireless charging module 32 in the wireless charging plate 3 and a second wireless charging module 11 in the wireless charging base 1, which can provide two wireless charging positions and more charging options. The wireless charging base 1 and the wireless charging plate 3 are rotatably connected through the support rod 2, so that the wireless charging plate 3 can be rotated more freely, and the wireless charging angle can be adjusted conveniently.

[0045] In specific use, the foldable wireless charger of the utility model can be used as a desktop wireless charger. When in use, the wireless charging base 1 is placed on the desktop, and the support rod 2 and the wireless charging plate 3 are opened for use. The wireless charging base 1 is provided with a power connection interface 15, and a power source is added through a data cable and a plug.

[0046] Specifically, the first wireless charging module is used to charge the first type of device to be charged, and the second wireless charging module is used to charge the second type of device to be charged. By setting the first wireless charging module 32 for the first type of device to be charged, and the second wireless charging module 11 for the second type of device to be charged, and setting two different types of wireless charging modules to provide charging positions for different types of devices, a more personalized charging service can be provided, and charging modules specifically designed for different types of devices are provided according to the type of device, which increases the charging efficiency and user experience. It can more effectively match the charging needs of the device, improve the charging efficiency and charging speed. This customized service helps to optimize the charging experience and ensure that the charging process is smoother and more efficient.

[0047] Specifically, the first type of device to be charged may be a Bluetooth headset, that is, the first wireless charging module 32 is used for charging the Bluetooth headset. When charging the Bluetooth headset, it can be directly placed on the wireless charging base 1 for wireless charging. The second type of device to be charged may be a mobile phone, that is, the first wireless charging module 32 is used for charging the mobile phone. When charging the mobile phone, the back of the mobile phone can be placed against the wireless charging plate 3 for charging. The first wireless charging module 32 and the second wireless charging module 11 may be magnetic wireless charging modules that can magnetically attract the charging object; a wireless charging expansion interface 14 may be further provided on the wireless charging base 1, and the wireless charging expansion interface 14 is connected to an external wireless charging device to provide more wireless charging positions.

[0048] like Figure 7 and Fig. 9 As shown, a receiving groove 311 corresponding to the support rod 2 is provided on the back of the housing 31, and one end of the support rod 2 is rotatably mounted in the receiving groove 311; when the wireless charging plate 3 is covered on the wireless charging base 1, the support rod 2 is received in the receiving groove 311. In this solution, the wireless charging plate 3 is covered on the wireless charging base 1 by setting the receiving groove 311, and the support rod 2 is hidden and received between the wireless charging base 1 and the wireless charging plate 3. When the wireless charging plate 3 is covered on the wireless charging base 1, the support rod 2 is received in the receiving groove 311, making the overall structure more compact, realizing the regular covering of the wireless charging plate 3 and the wireless charging base 1, ensuring the concealment and storage of the support rod 2, and improving the aesthetics and practicality of the product. At the same time, the receiving groove 311 hides the support rod 2 between the wireless charging plate 3 and the wireless charging base 1, reducing the entry of dust and debris, and enhancing the dustproof effect of the product. Specifically, the edges on both sides of the sinking slot 13 are provided with limiting grooves, and the limiting grooves are used to limit the first type of charging device to be charged against the wireless charging plate 3. By providing the limiting grooves on the edges on both sides of the sinking slot 13, the first type of charging device can be accurately positioned when placed to prevent the first type of charging device from sliding or moving. The design of the limiting grooves can ensure that the device can accurately rest against the wireless charging plate 3, avoiding the problem of reduced charging efficiency or charging failure due to inaccurate position of the first type of charging device.

[0049] Furthermore, if Figure 7 and Fig.10 As shown, a first mounting cavity 12 is provided on the top surface of the wireless charging base 1, and one end of the support rod 2 is rotatably mounted in the first mounting cavity 12. By rotatably mounting one end of the support rod 2 in the first mounting cavity 12 on the top surface of the wireless charging base 1, the connection between the support rod 2 and the wireless charging base 1 is ensured to be firm, thereby improving the stability and reliability of the installation.

[0050] A first inclined surface 21 tilted outward from bottom to top is provided on the side of the end of the support rod 2 that is rotatably connected to the first mounting cavity 12 and is away from the wireless charging base 1; when the support rod 2 is rotated and erected to the maximum angle, the first inclined surface 21 abuts against the outer edge 121 of the first mounting cavity 12, so that the angle α between the support rod 2 and the wireless charging base 1 is 80° to 100°. The first inclined surface 21 provided on the side of the end of the support rod 2 that is rotatably connected to the first mounting cavity 12 and is away from the wireless charging base 1 enables the support rod 2 to tilt outward under the restriction of the first inclined surface 21 when erected. When the support rod 2 is rotated and erected to the maximum angle, the first inclined surface 21 abuts against the outer edge 121 of the first mounting cavity 12, so that the angle between the support rod 2 and the wireless charging base 1 is controlled to be 80° to 100°. This angle control helps to optimize the posture of the support rod 2, ensure that the support rod 2 is at an appropriate tilt angle during use, so that the angle between the support rod 2 and the wireless charging base 1 is appropriate, fully supporting the charging device and maintaining a comfortable operating experience. The angle α can be 80°, 85°, 90°, 95°, or 100°.

[0051] like Fig. 9 and Fig.10 As shown, a supporting groove 22 is provided on one end of the support rod 2 that is rotatably connected to the receiving groove 311, and a side close to the wireless charging base 1; the bottom edge of the wireless charging plate 3 can be abutted against the supporting groove 22. The abutting groove 22 limits the rotation of the wireless charging plate 3, which is conducive to keeping the wireless charging plate 3 in a more suitable position and posture, thereby improving the wireless charging effect and convenience of use.

[0052] like Figure 1 and Figure 7 As shown, the top surface of the wireless charging base 1 is sunken to form a sunken slot 13, and the second wireless charging module 11 corresponds to the sunken slot 13, and the sunken slot 13 is used to place the second type of device to be charged. The sunken slot 13 can limit the second type of device to be charged to prevent the second type of device to be charged from falling out of the top surface of the wireless charging base 1 during the charging process. At the same time, the second wireless charging module 11 is arranged corresponding to the sunken slot 13 to facilitate the alignment and charging of the second type of device to be charged, thereby improving the charging efficiency. The user only needs to place the second type of device to be charged directly into the sunken slot 13 to ensure that the second type of device to be charged is aligned with the second wireless charging module 11. For example, when the second wireless charging module 11 is a Bluetooth headset, the user can directly place the Bluetooth headset in the sunken slot 13 for charging, and because the Bluetooth headset is in the sunken slot 13, it is not easy to fall out from the top surface of the wireless charging base 1. Specifically, when the wireless charging plate 3 is covered on the wireless charging base 1, the wireless charging plate 3 is embedded in the sunken groove 13, further reducing the volume after folding and storage.

[0053] Furthermore, a first storage cavity (not shown) adapted to the shape of the second type of device to be charged is provided on the top surface of the wireless charging base 1, and the first storage cavity is used to store the second type of device to be charged. Since the shape of the first storage cavity is adapted to the second type of device to be charged, it can ensure that the second type of device to be charged can be accurately stored in the first storage cavity, avoiding the second type of device to be charged from shaking or being unstable, and improving the storage and positioning of the second type of device to be charged. At the same time, since the first storage cavity can store and charge the second type of device to be charged, the folding wireless charger of the utility model can be directly used as a charging storage box for the second type of device to be charged, and can also be stored in the first storage cavity when the second type of device to be charged is not in use, and the wireless charging base 1 and the wireless charging plate 3 can also be further covered. For example, when the second type of device to be charged is a Bluetooth headset, two first storage cavities can be provided to store the left and right Bluetooth headsets respectively. At this time, the folding wireless charger can serve as a storage and charging box for the Bluetooth headset. In another embodiment, a second storage cavity (not shown) may also be provided on both sides of the storage groove 311, and the second storage cavity is used to store the second type of device to be charged. The second type of device to be charged can be stored in the second storage cavity, and the wireless charging plate 3 is covered on the wireless charging base 1, and the second type of device to be charged is stored when the wireless charging plate 3 is covered on the wireless charging base 1. At this time, the folding wireless charger can also be directly used as a charging storage box for the second type of device to be charged. Due to the setting of the storage groove 311, the space on both sides of the storage groove 311 is vacant and insufficiently utilized. In this solution, on the basis of the storage groove 311, a second storage cavity is provided on both sides thereof, and the space is fully and reasonably utilized to store the second type of device to be charged. The second storage cavity can be connected to the storage groove 311 or separated from the storage groove 311.
