[0023] The present utility model will be described in more detail below with reference to the drawings and embodiments.

[0024] The present utility model discloses a foldable three-position wireless charging device, in combination with Figures 1 to 6As shown in the figure, it includes a first housing 1, a second housing 2 and a third housing 3. The second housing 2 and the first housing 1 are stacked up and down, and the edge of the second housing 2 and the edge of the first housing 1 are hinged by a damping shaft assembly 4. A receiving groove 10 is formed at the top of the first housing 1. The third housing 3 is arranged in the receiving groove 10 and can be flipped by a preset angle relative to the receiving groove 10. A first charging area 11 is provided on the first housing 1, and a first wireless charging module 12 aligned with the first charging area 11 is arranged in the first housing 1. A second charging area 20 is provided on the second housing 2, and a second wireless charging module 21 aligned with the second charging area 20 is arranged in the second housing 2. A third charging area 30 is provided on the third housing 3, and a third wireless charging module 31 aligned with the third charging area 30 is arranged in the third housing 3.

[0025] In the above structure, the first housing 1 is used to be placed flat on a desktop or the like to play a bottom support role. The first charging area 11 provided thereon can be used to place devices such as wireless earphones and mobile phones. The second housing 2 can be unfolded or folded relative to the first housing 1. Based on the damping hinge action of the damping shaft assembly 4, the second housing 2 can be limited to a preset inclination angle, so as to support the mobile phone at a preset angle. At the same time, the second wireless charging module 21 is used to charge the mobile phone. On this basis, a receiving groove 10 is formed at the top of the first housing 1 of the present invention. The receiving groove 10 is used to accommodate the third housing 3, and at the same time, the third housing 3 can be flipped outwards relative to the receiving groove 10. When the smart watch leans on the third housing 3 and is aligned with the third charging area 30, the third wireless charging module 31 is used to charge the smart watch. Compared with the existing Z-shaped folding wireless charger, the present invention does not require three folding parts. Therefore, the structure of the three-position wireless charger of the present invention is more simplified, and the size of the folded product is also thinner and lighter, which can effectively save the manufacturing cost.

[0026] Please refer to Figure 1 and Figure 6 , in this embodiment, a through hole 13 is formed at the bottom of the receiving groove 10. Among them, the size of the through hole 13 is preferably such that a finger can pass through it. When it is necessary to unfold the third housing 3 relative to the receiving groove 10, the finger can be inserted into the through hole 13 and the third housing 3 can be pushed, so as to facilitate the unfolding of the third housing 3.

[0027] As a preferred method, the third charging area 30 is arranged in alignment with the through hole 13. Please refer to Figure 5, since the third charging area 30 is aligned with the through hole 13, after the first housing 1 and the second housing 2 are folded with each other, the folded charger can be placed upside down so that the through hole 13 faces upward. When the back of the smart watch covers the through hole 13, the third wireless charging module 31 inside the third charging area 30 can be used to wirelessly charge the smart watch. A central magnet 310 magnetically coupled with the smart watch is provided at the center of the third wireless charging module 31.

[0028] In order to achieve charging control and power supply, in this embodiment, please refer to Figure 3 , a battery 22 and a PCB board 23 are provided inside the second housing 2. The first wireless charging module 12, the second wireless charging module 21, the third wireless charging module 31 and the battery 22 are respectively electrically connected to the PCB board 23. The second wireless charging module 21 includes a wireless charging coil 210 and an annular magnetic attraction assembly 211 surrounding the outside of the wireless charging coil 210.

[0029] Please refer to Figure 2 , in order to accommodate the damping shaft assembly 4, in this embodiment, a shaft sleeve 14 is formed at the edge of the first housing 1. The damping shaft assembly 4 is inserted into the shaft sleeve 14. A hinge interface 24 is provided at the edge of the second housing 2, and the shaft sleeve 14 is arranged inside the hinge interface 24.

[0030] Regarding the preferred structure of the damping shaft assembly 4, please refer to Figure 4 , the damping shaft assembly 4 includes a fixed shaft rod 40. Both ends of the fixed shaft rod 40 are fixedly connected to the second housing 2. At least one set of damping mechanisms 45 is provided on the fixed shaft rod 40. The damping mechanism 45 includes an inner damping sleeve 41, an outer damping sleeve 42 and a spring 43 sleeved on the fixed shaft rod 40. The spring 43, the inner damping sleeve 41 and the outer damping sleeve 42 are arranged in sequence from the middle of the fixed shaft rod 40 to the end. The spring 43 is used to apply an elastic force to the inner damping sleeve 41 so that the end face of the inner damping sleeve 41 is in damping cooperation with the end face of the outer damping sleeve 42. The inner damping sleeve 41 is snap-fitted with the shaft sleeve 14, and the outer damping sleeve 42 is snap-fitted with the second housing 2.

[0031] Furthermore, a first end face tooth 410 is formed on the end face of the inner damping sleeve 41, and a second end face tooth 420 is formed on the end face of the outer damping sleeve 42. The first end face tooth 410 and the second end face tooth 420 are aligned and engaged with each other.

[0032] In the above structure, based on the meshing relationship between the first end face teeth 410 and the second end face teeth 420, the damping matching relationship between the inner damping sleeve 41 and the outer damping sleeve 42 is better. When the user flips the second housing 2 relative to the first housing 1, it is necessary to overcome the elastic force exerted by the spring 43 and make the first end face teeth 410 and the second end face teeth 420 rotate relative to each other. After the second housing 2 is flipped to a preset angle, by means of the elastic force exerted by the spring 43 and the engaging relationship between the first end face teeth 410 and the second end face teeth 420, the second housing 2 is reliably limited at the flipped angular position.

[0033] In order to better abut and cooperate with the spring 43, in this embodiment, a stepped convex shaft portion 44 is formed in the middle of the fixed shaft rod 40, and the spring 43 abuts between the convex shaft portion 44 and the inner damping sleeve 41.

[0034] As a preferred method, the first charging area 11 is provided between the shaft sleeve 14 and the receiving groove 10. Further, a hinge shaft 32 is formed at the edge of the third housing 3, and the hinge shaft 32 is rotatably connected to one end of the receiving groove 10 away from the first charging area 11.

[0035] In the above structure, the receiving groove 10 is away from the shaft sleeve 14, so that the hinge shaft 32 of the third housing 3 is as close as possible to the edge of the first housing 1. When the second housing 2 is unfolded relative to the first housing 1, it can provide enough space for the third housing 3 to flip outwards, so that the layout of the first housing 1, the second housing 2 and the third housing 3 is more reasonable, and at the same time it is also convenient for the user to perform folding and unfolding operations.

[0036] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements or improvements made within the technical scope of the present invention shall be included within the scope protected by the present invention.
