The first housing 11 may be in a regular shape, for example, the first housing 11 may be in a rectangular parallelepiped structure, a cylindrical structure, or a circular truncated cone structure. Of course, the first housing 11 may also be irregularly shaped. The embodiment of the present application does not limit the specific shape of the first housing 11. The first housing 11 is provided with a first accommodation space 110. Specifically, the first housing 11 may include a first top wall, a first side wall and a first bottom wall (none of which are numbered in the drawing), wherein the first top wall is disposed opposite to the first bottom wall, and the first side wall is connected between the first top wall and the first bottom wall to form the first receiving space 110. The first housing 11 is provided with a first wireless charging structure 111 therein, and the first wireless charging structure 111 is accommodated in the first accommodating space 110. When an electronic device with a wireless charging function is placed on the first housing 11, the first wireless charging structure 111 can wirelessly charge the electronic device.

The second housing 12 may be integrally formed (e.g., the second housing 12 may be machined or molded as a single structure), or the second housing 12 may be formed using a combination of structures (e.g., an inner frame structure forming one or more structures of an outer shell surface, etc.).

The second housing 12 may have a regular shape, for example, the second housing 12 may have a rectangular parallelepiped structure, a cylindrical structure, or a circular truncated cone structure. Of course, the second housing 12 may also be irregularly shaped. The embodiment of the present application does not limit the specific shape of the second housing 12. The second housing 12 is provided with a second accommodation space 120. Specifically, the second housing 12 may include a second top wall, a second side wall and a second bottom wall (none of which are numbered in the drawing), wherein the second top wall is disposed opposite to the second bottom wall, and the second side wall is connected between the second top wall and the second bottom wall to form the second accommodating space 120.

When an electronic device with a wireless charging function is placed on the second housing 12, the second wireless charging structure 121 can wirelessly charge the electronic device.

Wherein, the first shell 11 and the second shell 12 are symmetrically arranged, and the shape and the size of the second shell 12 are matched with the shape and the size of the first shell 11. For example, the first housing 11 and the second housing 12 may be both 92mm, 80mm, and 9.9mm long, wide, and high, respectively, so that the wireless charging device 10 has 92mm, 80mm, and 19.8mm long, wide, and high, respectively. The first housing 11 is provided with a first gear 112, the second housing 12 is provided with a second gear 122, and the first gear 112 is engaged with the second gear 122, so that the first housing 11 and the second housing 12 are rotatably connected.

When the electronic device is placed in the first charging region 113, the wireless charging apparatus 10 wirelessly charges the electronic device most efficiently through the first wireless charging structure 111.

It should be noted that the first charging area 113 may be larger than a projection of the first wireless charging structure 111 on the first housing 11 along the thickness direction of the first housing 11, and a position of the first charging area 113 on the first housing 11 corresponds to a projection of the first wireless charging structure 111 on the first housing 11 along the thickness direction of the first housing 11, which means that the first charging area 113 covers the projection of the first wireless charging structure 111 on the first housing 11 along the thickness direction of the first housing 11. Preferably, the center of the first charging region 113 coincides with the center of the projection of the first wireless charging structure 111 on the first housing 11 in the thickness direction of the first housing 11. For example, when the projection of the first wireless charging structure 111 on the first housing 11 along the thickness direction of the first housing 11 is a circle, the first charging region 113 may be a circle having a diameter larger than that of the projection and a center coinciding with that of the projection.

When the electronic device is placed in the second charging region 123, the wireless charging apparatus 10 wirelessly charges the electronic device most efficiently through the second wireless charging structure 121.

It should be noted that the second charging area 123 may be larger than a projection of the second wireless charging structure 121 on the second housing 12 along the thickness direction of the second housing 12, and a position of the second charging area 123 on the second housing 12 corresponds to the projection of the second wireless charging structure 121 on the second housing 12 along the thickness direction of the second housing 12, which means that the second charging area 123 covers the projection of the second wireless charging structure 121 on the second housing 12 along the thickness direction of the second housing 12. Preferably, the center of the second charging region 123 coincides with the center of the projection of the second wireless charging structure 121 on the second housing 12 in the thickness direction of the second housing 12. For example, when the projection of the second wireless charging structure 121 on the second housing 12 in the thickness direction of the second housing 12 is a square, the second charging region 123 may be a square having a side length greater than that of the projection and an intersection of diagonal lines coinciding with that of the projection.

the first gear has a first gear shaft and the second gear has a second gear shaft;

the wireless charging device further comprises a damping shaft sleeve, and the damping shaft sleeve is sleeved on the first gear shaft and the second gear shaft at the same time so as to enable the first gear to be meshed with the second gear;

gaps are formed among the damping shaft sleeve, the first gear shaft and the second gear shaft, and damping oil is filled in the gaps, so that the first shell and the second shell can be locked at any position when synchronously rotating around the symmetrical shafts of the first shell and the second shell.
