[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] refer to Figure 1-4 In one embodiment, a wireless charging device 100 with a suction cup includes: a main body 10, a suction cup 20, a connecting portion 30, and a sliding portion 40. The suction cup 20 is connected to the bottom surface of the main body 10. The connecting portion 30 is disposed inside the main body 10, and the connecting portion 30 communicates with the interior of the main body 10 and the suction cup 20. The sliding portion 40 is slidably connected to the main body 10, and the sliding portion 40 includes a plug 41. When the sliding portion 40 is in a first position (see...), Figure 1 When the sliding part 40 is in the second position, the plug 41 blocks the connecting part 30 and blocks the communication between the interior of the main body 10 and the suction cup 20; when the sliding part 40 is in the second position, the plug 41 disengages from the connecting part 30.

[0025] With the above-described structure, in use, the wireless charging device 100 can be placed on a supporting surface (e.g., a desktop). The user can apply pressure to the main body 10 to expel the air between the suction cup 20 and the supporting surface, thereby creating a vacuum that firmly adheres the main body 10 to the supporting surface. When not in use, the user can push the sliding part 40 to the second position, causing the plug 41 to disengage from the connecting part 30, thus connecting the interior of the main body 10 with the suction cup 20. Air inside the main body 10 enters through the connecting part 30 between the suction cup 20 and the supporting surface, allowing the main body 10 to be easily removed from the supporting surface. It should be noted that the atmospheric pressure inside the main body 10 is the same as the atmospheric pressure outside it.

[0026] In one embodiment, the main body 10 includes a base 11 and a rotating body 12 rotatably connected together. Figure 1The illustration shows a rotating body 12 stacked on a base 11. The rotating body 12 houses a wireless charging module capable of charging portable electronic devices. The rotating body 12 is rotatable relative to the base 11. It is understood that, in another embodiment, the main body 10 may be a single module, excluding the base and rotating body which are rotatable relative to each other.

[0027] In one embodiment, the body 10 includes a hollow shell 13, with the connecting portion 30 protruding from the inner surface of the shell 13. In this embodiment, the shell 13 is specifically the outer shell of the base 11, which is generally a cube with an opening at the top, including a base plate 14 and sidewalls 15 extending along the edge of the base plate 14. The connecting portion 30 is located in the space defined by the base plate 14 and the sidewalls 15, and protrudes from the inner surface of the base plate 14.

[0028] refer to Figure 5 In one embodiment, the connecting portion 30 is provided with a channel, the bottom surface of the housing 13 is provided with a connecting hole communicating with the channel, and the suction cup 20 is provided with a through hole 21 communicating with the connecting hole. Specifically, the base plate 14 is provided with a connecting hole 141 communicating with the channel of the connecting portion 30, and after the suction cup 20 is fixed to the outer surface of the base plate 14, its through hole 21 is exactly aligned with the connecting hole 141 on the base plate 14.

[0029] refer to Figure 6 In one embodiment, the connecting portion 30 is a column protruding from the inner surface of the base plate 14, which includes a side surface 31 that is substantially perpendicular to the inner surface of the base plate 14, and the channel of the connecting portion 30 intersects with the side surface 31 to form an opening 32.

[0030] refer to Figure 5 In one embodiment, the suction cup 20 is made of a flexible material capable of elastic deformation and includes a substrate 22 and a sidewall 23 extending along the edge of the substrate 22, the sidewall 23 being inclined relative to the substrate 22. When the wireless charging device 100 can be placed on a support surface (e.g., a desktop), the end of the sidewall 23 contacts the support surface. When the wireless charging device 100 is subjected to pressure from the user, the pressure is eventually transmitted to the sidewall 23, causing the sidewall 23 to elastically deform and shift relative to the substrate 22, thereby squeezing out the air between the suction cup 20 and the support surface, thus tightly adhering the body 10 to the support surface through vacuum negative pressure.

[0031] refer to Figure 3In one embodiment, the sidewall 15 of the housing 13 includes a through hole 151, and the sliding part 40 includes a body 42 and a button 43 connected to one end of the body 42. The button 43 is exposed through the through hole 151 in the sidewall 15 of the housing 13. With this configuration, the user can press the button 43 to push the sliding part 40 inward.

[0032] refer to Figure 6 In one embodiment, the body 42 of the sliding part 40 is provided with a receiving groove 44, the connecting part 30 is received in the receiving groove 44, and the plug 41 is provided at one end of the receiving groove 44, directly opposite the opening end of the channel of the connecting part 30, that is, directly opposite the opening 32 of the connecting part 30 on its side 31. Figure 1 In the state shown, the plug 41 abuts against the side 31 of the connecting part 30 and blocks the opening 32, thereby isolating the channel of the connecting part 30 from the interior of the housing 13, that is, isolating the interior of the housing 13 from the suction cup 20.

[0033] In one embodiment, the inner surface of the housing 13 is provided with two opposing guide walls 16, and the sliding portion 40 is slidably received within the space defined by the two guide walls 16. The two guide walls 16 define the sliding direction of the sliding portion 40. When the user presses the button 43, the sliding portion 40 slides along the direction defined by the guide walls 16. In one embodiment, the two sides of the body 42 of the sliding portion 40 face the two guide walls 16 respectively, and the two sides of the body 42 can be in contact with the two guide walls 16, or a gap is formed between the two sides of the body 42 and the two guide walls 16.

[0034] refer to Figure 6 and Figure 7 The body 42 of the sliding part 40 has recesses 45 at its two top edges, and the inner surfaces of the two guide walls 16 opposite to each other have protrusions 161, which are received in the two recesses 45. With this structure, the body 42 of the sliding part 40 is confined between the protrusions 161 and the inner surface of the bottom plate 14 of the housing 13, thus preventing it from escaping the space defined by the two guide walls 16.

[0035] In one embodiment, the main body 10 further includes an elastic member 50. An abutment wall 17 is provided on the inner surface of the housing 13 (i.e., the inner surface of the base plate 14). The two ends of the elastic member 50 are respectively located at the abutment wall 17 and the end of the body 42 of the sliding portion 40 opposite to the button 43, and are in a compressed state. Thus, the elastic member 50 applies a pushing force to the body 42, causing the plug 41 of the sliding portion to tightly abut against the side surface 31 of the connecting portion 30, thereby blocking the opening 32 on the side surface 31 of the connecting portion 30 and isolating the interior of the housing 13 from the suction cup 20.

[0036] refer to Figure 7 In one embodiment, the plug 41 is made of a flexible material. When the sliding portion 40 is in the first position, the plug 41 abuts against the end (i.e., side 31) of the opening end (i.e., opening 32) of the channel of the connecting portion 30 and undergoes elastic deformation. To ensure the sealing between the plug 41 and the side 31, a protruding annular portion 411 is provided at the end of the plug 41 opposite to the connecting portion 30. The annular portion 411 surrounds the opening 32 of the connecting portion 30. As the sliding portion 40 is pushed by the elastic member 50, the plug 41 presses tightly against the side 31 of the connecting portion 30, causing the annular portion 411 to undergo elastic deformation, thereby ensuring that the gap between the plug 41 and the side 31 of the connecting portion 30 and the opening 32 are isolated by the elastically deformed annular portion 411.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
