[0038] like Figure 1 , Figure 2 As shown, this utility model provides a wireless charging stand, including a base 1, a support plate 2 disposed on the base 1, and a wireless charging assembly 3 disposed on the support plate 2. The wireless charging assembly 3 includes a socket 31 and a wireless charging base 32. The socket 31 includes a housing 311 disposed on the support plate 2, a first circuit board 312 disposed within the housing 311, and a charging socket 313 connected to the first circuit board 312. The wireless charging base 32 includes a magnetic base 321 rotatably disposed on the socket 31, a second circuit board 322 disposed on the magnetic base 321, and a charging element 323 connected to the second circuit board 322. One of the first circuit board 312 and the second circuit board 322 is provided with an annular conductive layer group 324 closed in the circumferential direction, and the other is provided with a conductive post 314 abutting against the annular conductive layer group 324. Preferably, the conductive post 314 is an elastic conductive post 314.
[0039] like Figure 4 , Figure 5As shown, conductive posts 314 are disposed on the first circuit board 312. Components required for charging in the prior art can be disposed on the first circuit board 312. An annular conductive layer group 324 is disposed on the second circuit board 322. Three conductive posts 314 are provided, and the annular conductive layer group 324 includes three annular conductive layers spaced radially apart. The three conductive posts 314 move along the circumference of the three annular conductive layers to achieve current transmission. The charging port 313 of this invention is used to connect a data cable / charging cable to supply power to the wireless charging component 3. The wireless charging component 3 conducts electricity through the contact between the conductive posts 314 on the first circuit board 312 and the annular conductive layer group 324 on the second circuit board 322. Therefore, even when the wireless charging base 32 rotates to different angles, current transmission can still be achieved to enable charging of electronic products such as tablets and mobile phones magnetically attached to the wireless charging base 32.
[0040] This invention can be used as a stand and charger for electronic products such as tablets and mobile phones. When charging tablets or mobile phones, simply connect the data cable / charging cable to the charging port 313. Moreover, since the wireless charging component 3 achieves the connection between the first circuit board 312 and the second circuit board 322 through the contact conduction between the conductive post 314 and the annular conductive layer group 324, the current transmission is realized. The wireless charging stand 32 can be rotated to different angles such as landscape or portrait mode to realize the charging function. During the rotation of the wireless charging stand 32, the port base 31 does not need to rotate, so the position of the charging port 313 on the port base 31 will not rotate, and the connected data cable / charging cable does not need to be changed, improving the convenience of use.
[0041] The wireless charging base 32 and the socket base 31 are magnetically or rotatably connected, and can be rotatably connected by a damping shaft.
[0042] In one embodiment, such as Figure 1 As shown, the charging element 323 includes a charging contact 325, which is disposed inside the magnetic base 321 and protrudes from the side of the magnetic base 321 opposite to the socket 31. It can charge and support electronic products with power-receiving contacts, such as iPads.
[0043] In one embodiment, the charging element 323 includes a charging transmitting coil disposed inside the magnetic base 321. This allows for the charging of mobile phones, tablets, and other devices equipped with a charging receiving coil.
[0044] In one embodiment, such as Figure 3As shown, the magnetic base 321 includes a front cover plate 3211, a front frame 3212, a rear frame 3213, and a rear cover plate 3214 arranged sequentially. The second circuit board 322 is disposed on the side of the rear cover plate 3214 facing the socket 31 for easy assembly. The rear cover plate 3214 and the rear frame 3213 are provided with through holes for the circuit to pass through. The front frame 3212 is provided with magnets, and multiple magnet holes can be provided in the front frame 3212 for installing magnets. The positions of the magnet holes can also correspond one-to-one with the magnetic positions of the iPad to better realize the magnetic function. The front cover plate 3211 and the rear cover plate 3214 can both be made of PC+silicone material, about 0.6mm thick, to cover the inside of the magnets and achieve an aesthetically pleasing appearance.
[0045] In one embodiment, the support plate 2 is provided with a cable guide hole 21 extending along its length. This facilitates the insertion of the data cable / charging cable into the charging port 313 of the socket 31 through the cable guide hole 21, improving ease of use.
[0046] In one embodiment, the support plate 2 is rotatably connected to the base 1 via a damping shaft; or / and the support plate 2 is rotatably connected to the socket 31 via a damping shaft. This allows for adjustment of the support angle and improves ease of use.
[0047] In one embodiment, the base 1 is a magnetic base 1, so that the base 1 can be magnetically attached to the metal surface.
[0048] In one embodiment, such as Figure 6 As shown, an anti-slip layer 17 is provided at the bottom of the base plate 11 to improve the anti-slip effect of this utility model.
[0049] In one embodiment, such as Figure 1 , Figure 6 As shown, the base 1 includes a base plate 11 and a reinforcing plate 12. The reinforcing plate 12 is disposed at the center of the base plate 11 and has an extension portion 121 extending to the edge. The support plate 2 is rotatably disposed at the edge of the extension portion 121 to improve the support stability of electronic products such as mobile phones and tablets.
[0050] In one embodiment, a gear 13 is provided at the top of the base plate 11, and a receiving cavity 122 adapted to the gear 13 is provided at the bottom of the reinforcing plate 12. A rotating wheel 14 rotatably connected to the reinforcing plate 12 is provided in the receiving cavity 122, and the rotating wheel 14 is also fixedly connected to the gear 13. A cam groove 123 communicating with the receiving cavity 122 is provided at the bottom of the reinforcing plate 12 on one side. A cam 15 meshing with the gear 13 is provided in the cam groove 123, and a spring 16 is provided between the cam 15 and the reinforcing plate 12.
[0051] In this embodiment, without external force, the engagement of the cam 15 and gear 13 by the spring 16 restricts the rotation of the reinforcing plate 12. When a rotational force is applied, the elastic force of the spring 16 is overcome, allowing the cam 15 to rotate around the gear 13, thereby causing the reinforcing plate 12 to rotate around the base plate 11. This embodiment achieves damped rotation and fixation of the reinforcing plate 12 around the base plate 11, improving ease of use.
[0052] Those skilled in the art should understand that the specific embodiments described above are merely examples and not limitations. Various modifications, combinations, partial combinations, and substitutions can be made to the embodiments of this utility model according to design requirements and other factors, as long as they are within the scope of the appended claims or their equivalents, and thus fall within the scope of the rights to be protected by this utility model.
