The third wireless charging unit 6 is arranged on (e.g.,in) the third housing 3 and configured to wirelessly charge a third electronic device 61 to be charged on the third housing 3.

[0024] According to the wireless charger of the example of the disclosure, the wireless charger has a variety of usage forms by switching and combining folded states of the first case 1, the second case 2, and / or the third case 3. The first case 1 provides a base for folding and storing the second case 2 and the third case 3. The second case 2 is stored on the first surface 11 of the first case 1 (e.g., in close contact with, located on, resting on), and the third case 3 is stored on the second surface 12 of the first case 1. The second wireless charging unit 5 is stored together with the second case 2 on the first surface 11 of the first case 1, and the third wireless charging unit 6 is stored together with the third case 3 on the second surface 12 of the first case 1.The use of the second wireless charging unit 5 and the third wireless charging unit 6 does not interfere with each other. The second wireless charging unit 5 and the third wireless charging unit 6 can be used independently or simultaneously, and a space of the first surface 11 and a space of the second surface 12 of the first housing 1 are fully utilized. The wireless charging unit is compact in structure, small in volume after folding, and convenient to carry and store.

[0026] In some examples, when the second housing 2 is in the second position, a first included angle is formed between the second housing 2 and the first surface 11 and may be 60 degrees. A magnetic attraction structure is provided in the second housing 2 and can attract the second device 51 to be charged onto a surface of the second housing 2 away from the first housing 1, preventing the second device 51 to be charged from falling or moving. When the second device 51 to be charged is configured as a mobile phone, the magnetic attraction structure provided in the second housing 2 causes the second housing 2 to have a magnetic attraction function to attract the mobile phone and prevent the mobile phone from falling. The mobile phone is attracted to an inclined surface of the second housing 2.At this time, the tilted second housing 2 in the wireless charger functions as a mobile phone stand, allowing the mobile phone to be wirelessly charged while being operated or viewed by a user, which can meet the charging needs of mobile phones of various sizes on the market. It is understood that the second housing 2 may be provided with a limiting protrusion serving as a limiting support for a bottom of the mobile phone to prevent the mobile phone from slipping in a tilted state, which will not be described in detail here.

[0027] It is understood that while the second housing 2 is inclined, a space is opened between the second housing 2 and the first surface 11 of the first housing 1, so that the first device 41 to be charged can be placed on the first surface 11 and the first wireless charging unit 4 can charge the first device 41 to be charged on the first surface 11.

[0028] With reference to Fig. 2, in some examples, the first housing 1 is provided with a storage container 121 (e.g., a storage space, a storage cavity, a storage recess) on a second side wall thereof, into which the third housing 3 is to be embedded.

[0029] With reference to Fig. 3 and Fig. 4, in some examples, when the third housing 3 is in the fourth position, a second included angle is formed between the third housing 3 and the first surface 11, which may also be 60 degrees, that is, the third housing 3 is rotated 240 degrees from the second surface 12 of the first housing 1 to the fourth position. When the third device 61 to be charged is configured as a watch that can be wirelessly charged, a watch face may be hung on the inclined third housing 3, and a watchband may be supported on a table to form a support. It is understood that the third housing 3 may also be provided with a magnetic attraction structure for attracting the watch. The third housing 3 in the fourth position functions as a watch stand, allowing the watch to be wirelessly charged while information on the watch face can be conveniently viewed by a user.The third case 3 may be provided with a limiting protrusion serving as a limiting support for a bottom of the dial of the watch to prevent the watch from slipping in an inclined state, which is not described in detail here.

[0030] With reference to Fig. 5 shows Fig. 5 is a schematic structural view of a rotational positioning unit 7 in a wireless charger according to an example of the present disclosure. In some examples, the wireless charger further includes a rotational positioning unit 7 disposed between the first housing 1 and the second housing 2. A position of the second housing 2 is switched between the first position and the second position by the rotational positioning unit 7, so that the second housing 2 is in the first position or the second position.

[0031] With reference to Fig. 5, Fig. 6 and Fig. 7 shows Fig. 6 is a schematic structural view of a rotary shaft roller 71 (e.g., a first rotary shaft, a cylindrical rotary shaft component) and a support plate 731 in a wireless charger according to an example of the disclosure. Fig. Figure 7 shows a schematic structural view of a rotary shaft piece 72 (e.g., a second rotary shaft) in a wireless charger according to an example of the present disclosure. In some examples, the rotary positioning unit 7 includes a rotary shaft roller piece 71 and a rotary shaft piece 72, wherein the rotary shaft roller piece 71 is fixedly connected to the first housing 1, and the rotary shaft roller piece 71 is fixedly provided with a stationary positioning block 711. Referring to Fig. 8 and Fig. 9 shows Fig. 8 is a schematic structural view of a rotary shaft roller 71 and a rotary shaft roller 72 in a wireless charger according to an example of the present disclosure, and Fig. Figure 9 shows a partially enlarged schematic view at A in Fig. 8. The rotary shaft piece 72 is fixedly connected to the second housing 2, and the rotary shaft piece 72 is rotatably connected to the rotary shaft rolling piece 71. Specifically, the rotary shaft piece 72 includes a shaft body 720, a follow-up positioning block 721, and a fixed block 722. The follow-up positioning block 721 is fixedly disposed on a circumferential outer wall of the shaft body 720. One end of the shaft body 720 is configured to be rotatably connected to the rotary shaft rolling piece 71; the other end of the shaft body 720 is fixedly connected to the fixed block 722. The fixed block 722 is configured to be fixedly connected to the second housing 2. The rotary shaft piece 72 is fixedly connected to the second housing 2 through the fixed block 722.

[0032] The follow-up positioning block 721 is provided with a first rotational positioning surface 7211 and a second rotational positioning surface 7212. When the first rotational positioning surface 7211 abuts the stationary positioning block 711, the second housing 2 is in the first position. When the second rotational positioning surface 7212 abuts the stationary positioning block 711, the second housing 2 is in the second position. For example, if the first included angle is 60 degrees, after the follow-up positioning block 721 is rotated by 60 degrees, a case where the first rotational positioning surface 7211 abuts the first stationary positioning block 711 is switched to a case where the second rotational positioning surface 7212 abuts the stationary positioning block 711. In this 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 the stationary positioning block 711 in the second position, the second housing 2 may not be able to rotate further and may remain in the second position. It should be understood that the rotation positioning unit 7 may be in a form in which a rotation shaft connection 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.
