A position of the second housing 2 is switched between the first position and the second position by the rotation positioning assembly 7, so that the second housing 2 is in the first position or the second position.

Referring to FIGS. 5, 6, and 7, FIG. 6 shows a schematic structural view of a rotating shaft rolling piece 71 (e.g., a first rotating shaft, a rotating shaft cylindrical component) and a bracket board 731 in a wireless charger according to an example of the disclosure. FIG. 7 shows a schematic structural view of a rotating shaft piece 72 (e.g., a second rotating shaft) in a wireless charger according to an example of the present disclosure. In some examples, the rotation positioning assembly 7 includes a rotating shaft rolling piece 71 and a rotating shaft piece 72, the rotating shaft rolling piece 71 is fixedly connected with the first housing 1, and the rotating shaft rolling piece 71 is fixedly provided with a stationary positioning block 711. Referring to FIG. 8 and FIG. 9, FIG. 8 shows a schematic structural view of a rotating shaft rolling piece 71 and a rotating shaft piece 72 in a wireless charger according to an example of the present disclosure, and FIG. 9 shows a partially enlarged schematic view at A in FIG. 8. The rotating shaft piece 72 is fixedly connected with the second housing 2, and the rotating shaft piece 72 is rotatably connected with the rotating shaft rolling piece 71. Specifically, the rotating shaft piece 72 includes a shaft body 720, a follow-up positioning block 721 and a fixed block 722.

The fixed block 722 is configured to be fixedly connected with the second housing 2. The rotating shaft piece 72 is fixedly connected with the second housing 2 through the fixed block 722.

The follow-up positioning block 721 is provided with a first rotation positioning surface 7211 and a second rotation positioning surface 7212. When the first rotation positioning surface 7211 abuts against the stationary positioning block 711, the second housing 2 is in the first position. When the second rotation positioning surface 7212 abuts against the stationary positioning block 711, the second housing 2 is in the second position. For example, when the first included angle is 60 degrees, after the follow-up positioning block 721 is rotated 60 degrees, a case where the first rotation positioning surface 7211 abuts against the first stationary positioning block 711 is switched to a case where the second rotation positioning surface 7212 abuts against the stationary positioning block 711. In that case, the second housing 2 is switched from the first position to the second position by rotation. Since the second rotation positioning surface 7212 abuts against the stationary positioning block 711 in the second position, the second housing 2 might not continue rotating and may remain in the second position. It can be understood that the rotation positioning assembly 7 can be in a form that a rotating shaft connecting structure fits a locking bolt, as long as the second housing 2 can be positioned after being rotated relative to the first housing 1, which will not be described in detail herein.

In some examples, the turning assembly 8 includes a turning shaft 81 and a turning sleeve 82. The turning shaft 81 is fixedly connected with the third housing 3, the turning sleeve 82 is fixedly connected with the first housing 1, and the turning shaft 81 is rotatably connected with the turning sleeve 82.

In some examples, the turning assembly 8 includes a first power supply protection assembly 83 disposed between the first housing 1 and the third housing 3. When the third housing 3 is in the third position, the first power supply protection assembly 83 is configured to cut off (e.g., block, disconnect) a third power supply circuit provided by the third wireless charging unit 6.

Specifically, the third housing 3 is provided with a turning cantilever 31 configured to be connected with the turning assembly 8. The turning cantilever 31 is provided with a mounting cavity 311 and a mounting cover plate 312 configured to close the mounting cavity 311.

One end of the turning shaft 81 is in a cylindrical shape, extends into the turning sleeve 82, and is rotatably connected with the turning sleeve 82. The other end of the turning shaft 81 is in a square column shape and extends into the mounting cavity 311, and a second mounting plate 811 is fixed at the end of the turning shaft 81 in the square column shape, and the second mounting plate 811 is fixedly connected with the third housing 3 in the mounting cavity 311, so that the turning shaft 81 is relatively fixedly connected with the third housing 3 through the second mounting plate 811, thereby enabling the third housing 3 to turn relative to the first housing 1

Referring to FIGS. 11 and 12, FIG. 12 shows a partially enlarged schematic view at B in FIG. 11. In some examples, the first power supply protection assembly 83 includes a first press-fit switch 831 and a turning triggering block 832. The first press-fit switch 831 is fixedly connected with the first housing 1, and the turning triggering block 832 is fixedly connected with the third housing 3. When the third housing 3 is in the third position, the turning triggering block 832 is separated from a first trigger 8311 provided on a side wall of the first press-fit switch 831, the first press-fit switch 831 is turned off, and the third power supply circuit is disconnected. When the third housing 3 is in the fourth position, the turning triggering block 832 abuts against the first trigger 8311 of the first press-fit switch 831, and the first press-fit switch 831 is turned on, and the third power supply circuit is connected.

Specifically, the turning triggering block 832 is fixedly disposed on an outer wall of the turning cantilever 31, and the first press-fit switch 831 is fixedly connected with the first housing 1. When the second included angle is 60 degrees, after the turning triggering block 832 is rotated 270 degrees, a case where the turning triggering block 832 is separated from the first press-fit switch 831 is switched to a case where the turning triggering block 832 abuts against the first press-fit switch 831, that is, the third housing 3 is switched from the third position to the fourth position through the turning.

If a coil of the third wireless charging unit 6 cannot stop working in time when the third housing 3 in the wireless charger is stored on the second surface 12 of the first housing 1, the coil of the third wireless charging unit 6 may heat up due to a metal medium covered thereon, resulting in burning out.
