Combined with the design of the second magnetic member 51, the second wireless charging module 52, the third wireless charging module (not shown in the figures), and the power bank module (not shown in the figures), it not only supports wireless charging for various types of mobile terminals but also provides power through the power bank module (not shown in the figures), offering rich functionality. Examples of mobile terminals include smartphones and smartwatches.

[0028] Specifically, in this embodiment, the first folding part 1 includes a first base 11 and a pad 12 that are stacked on top of each other. The length and width dimensions of the first base 11 and the pad 12 are the same, and the thickness of the first base 11 is greater than the thickness of the pad 12. A first charging part 4 is disposed on the first base 11, and the pad 12 is provided with a corresponding clearance through hole 120 for the first charging part 4 to pass through. The diameter of the clearance through hole 120 is adapted to the diameter of the first charging part 4. The first base 11 is rotatably connected to the second folding part 2 through a first damping connector 71. Under the action of the first damping connector 71, the first base 11 and the second folding part 2 can be folded into a parallel, folded state, and the first base 11 and the second folding part 2 can be rotated at a suitable angle to be in an unfolded state.

[0029] The first charging unit 4 includes an annular groove 401 on the first base 11, a boss 402 formed at the center of the annular groove 401, and an arc-shaped flange 403 on the boss 402. The first magnetic chuck 41 and the first wireless charging module 42 are both located within the arc-shaped flange 403, with the first magnetic chuck 41 positioned on the side of the first wireless charging module 42 away from the boss 402. The first magnetic chuck 41 has an arc shape, and the curvature of its outer periphery matches the curvature of the inner periphery of the arc-shaped flange 403.

[0030] The annular groove 401 is embedded with an annular partition 43, and the protrusion 402 is located at the center of the annular partition 43. The annular partition 43 has an annular wall protruding from the arc-shaped flange 403. A circular pad 44 covering the first magnetic member 41 is provided inside the annular wall. The first magnetic member 41 is sealed in the annular wall by the circular pad 44. During wireless charging, the smartphone is placed on the circular pad 44, and the smartphone is magnetically supported by the first magnetic member 41. Then, the smartphone is wirelessly charged by the first wireless charging module 42.

[0031] Specifically, in this embodiment, the second folding part 2 includes a second base 21 and a through groove 22 disposed on the second base 21; the second charging part 5 is rotatably connected to the through groove 22 through a second damping connector 72. Under the action of the second damping connector 72, the second charging part 5 can rotate from inside the through groove 22 to outside the through groove 22 in an open state, or be housed in the through groove 22 in a retracted state, facilitating wireless charging of the smartwatch. The diameter of the through groove 22 is adapted to the second charging part 5. One end of the second base 21 is connected to the first damping connector 71, and the other end of the second base 21 is rotatably connected to the third folding part 3 through a third damping connector 73. Under the action of the third damping connector 73, the second base 21 and the third folding part 3 can be folded into a retracted state that is parallel to each other, or the second base 21 and the third folding part 3 can be rotated at a suitable angle to an unfolded state.

[0032] The second base 21 is further provided with an annular baffle 211, which is located at one side of the groove edge of the through groove 22 and extends radially toward the center of the through groove 22. It is used to support and block the second charging part 5, preventing the second charging part 5 from rotating excessively and turning out of the through groove 22 from the other side. A receiving cavity for accommodating the second charging part 5 is formed between the annular baffle 211 and the inner peripheral sidewall of the through groove 22. When the second charging part 5 is accommodated in the receiving cavity, the second charging part 5 does not protrude from the receiving cavity, so that the first folding part 1 and the second folding part 2 can be folded into a stowed state without obstruction.

[0033] The second base 21 is further provided with a mounting groove 210, which is located on the other side of the through groove 22 and extends away from the center of the through groove 22. The connecting end of the second charging part 5 is connected to the second damping connector 72, which is rotatably connected within the mounting groove 210, providing suitable mounting and rotational space for the second charging part 5, facilitating its retraction or opening. The second damping connector 72 is, for example, a second damping shaft. After the connecting end of the second charging part 5 extends into the mounting groove 210 and is connected in place via the second damping shaft, a rotatable connection between the second charging part 5 and the second base 21 is achieved. The second magnetic component 51 is, for example, a magnetic ring.

[0034] It should be noted that the layout of the second magnetic member 51 and the second wireless charging module 52 in the second charging unit 5 can refer to the layout of the first magnetic member 41 and the first wireless charging module 42 in the first charging unit 4 or any suitable layout in the prior art.

[0035] Specifically, in this embodiment, a first protrusion 111 is provided on one surface of the first base 11 near the second base 21, and a first recess 201 for inserting the first protrusion 111 is provided at one end of the second base 21 near the first base 11. The first protrusion 111 is connected to the first recess 201 through a first damping connector 71. The first damping connector 71 is, for example, a first damping shaft. After the first protrusion 111 extends into the first recess 201 and is connected in place through the first damping shaft, a rotational connection between the first base 11 and the second base 21 is achieved.

[0036] Specifically, in this embodiment, the third folding portion 3 includes a third base 31 and a power interface 32 disposed on the third base 31; both the third wireless charging module (not shown in the figure) and the power bank module (not shown in the figure) are disposed within the third base 31, and the power interface 32 is electrically connected to the power bank module (not shown in the figure), greatly improving ease of use. The third wireless charging module (not shown in the figure) and the power bank module (not shown in the figure) can be disposed at any suitable position within the third base 31, for example, the third wireless charging module (not shown in the figure) can correspond to the wireless charging area on the third base 31. The wireless charging area can be divided according to actual application needs. To avoid mutual interference between the third wireless charging module (not shown in the figure) and the power bank module (not shown in the figure), they can be distributed at intervals within the third base 31.

[0037] The third base 31 is connected to the third damping connector 73. On one surface of the third base 31, near the second base 21, a second protrusion 311 is provided. The second base 21, at its end near the third base 31, has a corresponding second recess 202 for inserting the second protrusion 311. The second protrusion 311 is connected to the second recess 202 via the third damping connector 73. The third damping connector 73 is, for example, a third damping shaft. After the second protrusion 311 extends into the second recess 202 and is connected in place via the third damping shaft, a rotational connection is achieved between the third base 31 and the second base 21. The shape and structure of the third damping shaft are the same as the first damping shaft.

[0038] It should be noted that the structure and application principle of the first wireless charging module 42, the second wireless charging module 52 and the third wireless charging module (not shown in the figure) are relatively existing. For example, they all adopt wireless charging modules including wireless charging coils. In actual application, any suitable existing technology can be referred to, as long as wireless charging can be achieved. The mobile power module (not shown in the figure) is also relatively existing. For example, it includes power modules, transformer modules, etc. The power module is such as a battery cell. This embodiment does not make any specific limitations.

[0039] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
