Embodiment 1
[0037] Such as Figure 1-4 As shown, this embodiment provides a wireless charging device, which is mainly used to be placed under a table to charge terminal devices such as mobile phones and notebooks placed on the table. The wireless charging device includes a support shaft 1 , a rotating assembly 2 and a wireless charging coil 3 . The supporting shaft 1 is used for the rotational connection of the rotating assembly 2, and may be a rotating shaft or a fixed shaft. The rotating assembly 2 includes a rotating arm 21 and a planar link mechanism 22 . After one end of the rotating arm 21 is rotationally connected with the support shaft 1 , the other end is connected with the planar link mechanism 22 , so that the planar link mechanism 22 can realize the rotation in the horizontal plane. The rotating arm 21 serves as a support for supporting the rotation of the planar link mechanism 22 , and the rotating arm 21 may be a linear structure or a bent structure. When the rotating arm...
Embodiment 2
[0042] Embodiment 2 is formed on the basis of Embodiment 1. Through the deformation design of the overall structure of the rotating assembly, the planar linkage mechanism runs more smoothly, thereby improving the stability of the wireless charging coil during rotation. specifically:
[0043] Such as Figure 1-4 As shown, the rotating assembly 2 further includes a support ring 23 , which is a closed ring structure, supported and fixed by at least two rotating arms 21 . Preferably, the supporting ring 23 is supported by three rotating arms 21 with an included angle of 120°, and the three rotating arms 21 can be rotatably connected to the supporting shaft 1 through an annular plate. Of course, at this time, the single rotating arms 21 rotate synchronously and in the same direction at the same time, and then the supporting ring 23 rotates. One end of the third connecting rod 223 is hinged to the supporting ring 23 , preferably, the surface of the supporting ring 23 hinged to the...
Embodiment 3
[0046] Embodiment 3 is a wireless charging platform formed on the basis of Embodiment 1 or Embodiment 2, such as Figure 1-5 As shown, it includes the use of the wireless charging device described in Embodiment 1 or Embodiment 2, and also includes a table 5 . The rotating assembly 2 is located below the table 5, that is, the wireless charging coil 3 is located below the table 5. Preferably, the distance between the wireless charging coil 3 and the table 5 is 1-2 mm. The wireless charging coil 3 can basically reach any position of the table 5 through the rotational movement of the rotating assembly 2 and the setting of the lengths of the three links in the planar linkage 22, thereby charging the electronic terminal equipment placed on the table 5 .
[0047] Further preferably, a positioning device 4 is also included, and the positioning device 4 is used for positioning the electronic terminal equipment placed on the table 4, feeding back the signal to the electric actuator, an...
