[0033] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.

[0034] The present invention provides a wireless charger 1000 for charging a mobile terminal. Figures 1 to 4 As shown, the wireless charger 1000 includes a base 10, a support plate 20, and a cooling assembly 30. A first receiving groove 11 is provided on the top surface of the base 10; the support plate 20 is hinged to the base 10, and a first charging coil (not shown in the figure) is installed on the support plate 20; the cooling assembly 30 is installed on the support plate 20 for cooling the mobile terminal, and the cooling assembly 30 is located on the side of the support plate 20 facing the base 10; wherein, when the support plate 20 and the base 10 are folded, the cooling assembly 30 can be accommodated in the first receiving groove 11. The present application can solve the problem in the prior art that the cooling fan of the wireless charger 1000 is prone to dust accumulation, resulting in a decrease in heat dissipation performance. It can not only dissipate heat and cool the mobile terminal during charging, but also effectively prevent dust accumulation when idle, thereby maintaining a good heat dissipation effect.

[0035] Specifically, the support plate 20 can rotate relative to the base 10, allowing the cooling assembly 30 on the support plate 20 to be accommodated in the first receiving groove 11. The first receiving groove 11 prevents dust and hair from adhering to the cooling assembly 30, thereby preventing dust accumulation in the cooling assembly 30 when the wireless charger 1000 is idle, maintaining its good heat dissipation effect, reducing the user's cleaning frequency, and improving the user experience. In addition, the first receiving groove 11 provides additional protection for the cooling assembly 30, reducing the risk of collision.

[0036] It is worth mentioning that by implementing this solution, the wireless charger 1000 not only effectively reduces the volume occupied by the external space after being folded and stored, but also because the refrigeration component 30 is hidden in the first receiving groove 11, the overall appearance of the wireless charger 1000 is neater and more beautiful.

[0037] In this application, the support plate 20 is used to support the mobile terminal. For example, a mobile phone is placed on the support plate 20, and the first charging coil aligns with the charging coil on the back of the phone to charge. Optionally, the first charging coil is located on the side of the support plate 20 opposite the hinged side of the base 10 to provide suitable space for the mobile phone.

[0038] In this application, since the support plate 20 is hingedly connected to the base 10, the user can adjust the angle between the support plate 20 and the base 10 to position the phone in an ideal tilted position, making it convenient to observe and operate the phone screen at any time during charging. When not in use, the support plate 20 can also be folded with the base 10 to reduce the space occupied and facilitate storage.

[0039] To enhance the stability of the rotational connection between the support plate 20 and the base 10, in one embodiment, a rotating base 21 is protruding from the side of the support plate 20 facing the base 10. The base 10 is provided with a mounting slot 12, and the rotating base 21 is partially accommodated in the mounting slot 12 and rotatably connected to the wall of the mounting slot 12. This provides protection for the rotating base 21, preventing damage to the rotational connection. Furthermore, since the rotating base 21 is partially concealed within the mounting slot 12, the overall appearance is more uniform.

[0040] Preferably, the base 10 includes a side surface adjacent to the top surface, and the mounting groove 12 is provided at a position adjacent to the side surface of the top surface. The mounting groove 12 extends through the side surface to form an opening, so that the end of the rotating base 21 connected to the support plate 20 can be rotated out of the opening. In this way, the rotating base 21 can be rotated out of the mounting groove 12 and the opening, so that the rotating base 21 has a larger adjustment range, providing users with more adjustment angle options. This wireless charger 1000 is more flexible and enhances the user experience.

[0041] In one embodiment, the cooling assembly 30 includes a housing 31 protruding from the side of the support plate 20 facing the base 10. The first receiving groove 11 is a contoured groove similar in shape to the housing 31. This arrangement further prevents dust from entering the cooling assembly 30, while also making the structure more compact and the overall appearance more uniform.

[0042] Specifically, the refrigeration assembly 30 also includes a cooling fan (not shown in the figure), which is installed in the shell 31. The shell 31 is provided with an air inlet and an air outlet, and the groove wall of the first receiving groove 11 is blocked in front of the air inlet and the air outlet.

[0043] Optionally, the cooling assembly 30 further includes a semiconductor cooling sheet (not shown in the figure), which is installed on the side of the cooling fan facing away from the housing 31 for more efficiently cooling the mobile terminal.

[0044] Optionally, the refrigeration assembly 30 further includes a switch button 32, which is disposed on the support plate 20. Optionally, the switch button 32 is disposed on the outer peripheral surface of the support plate 20, and the switch button 32 is electrically connected to the semiconductor refrigeration plate and the cooling fan for controlling the opening and closing.

[0045] In one embodiment, a heat-conducting layer 23 is provided on the side of the support plate 20 facing away from the cooling assembly 30. This layer is designed to contact the mobile terminal during charging. This arrangement effectively improves heat conduction between the cooling assembly 30 and the mobile terminal, allowing the mobile terminal to dissipate heat and cool down more quickly. Specifically, the heat-conducting layer 23 can be made of a material with excellent thermal conductivity, such as copper, aluminum, or other metals or thermally conductive ceramics.

[0046] In one embodiment, the wireless charger 1000 further includes a damping shaft (not shown), through which the base 10 is connected to the support plate 20. This arrangement provides a damping force, allowing the support plate 20 to remain more stably in the desired position after adjusting its angle, preventing displacement of the support plate 20 due to external forces or vibrations, and improving connection reliability.

[0047] In one embodiment, the support plate 20 is further provided with a second charging coil (not shown); and / or, the base 10 is provided with a third charging coil (not shown). With this configuration, the wireless charger 1000 can charge multiple devices simultaneously. For example, the second charging coil can be used to charge a watch or bracelet, and the third charging coil can charge the earphone compartment.

[0048] The placement of the second and third charging coils can be freely adjusted based on actual design requirements and are not limited here. For example, the second charging coil is placed on the side of the first charging coil close to the base 10, and the third charging coil is placed adjacent to the hinged joint between the base 10 and the support plate 20.

[0049] Optionally, a placement slot 13 for placing the earphone is provided on the base 10, and the third charging coil is arranged at the bottom of the placement slot 13 to facilitate the user to place the earphone more accurately for alignment charging.

[0050] In one embodiment, the wireless charger 1000 further includes a rotating plate 40, on which a second charging coil is mounted. A second receiving slot 24 is provided on the support plate 20. The rotating plate 40 is rotatably connected to the wall of the second receiving slot 24, allowing the rotating plate 40 to be rotated in and out of the second receiving slot 24. This arrangement not only better supports the watch or bracelet, but also allows for stable charging. Furthermore, the rotating plate 40 is rotatably connected to the side of the second receiving slot 24, allowing the user to choose whether to rotate the rotating plate 40 to charge according to their needs. This makes the overall structure of the wireless charger 1000 more compact and improves space utilization.

[0051] Preferably, the second receiving groove 24 is provided on the side of the support plate 20 facing the base 10. In this way, when the support plate 20 and the base 10 are folded, the base 10 can block the notch of the second receiving groove 24, thereby preventing the rotating plate 40 from contacting the outside in the stored state, thereby improving the protection of the rotating plate 40.

[0052] In one embodiment, the rotating plate 40 includes a free end 41 and a hinged end 42 disposed opposite to each other. The hinged end 42 is rotatably connected to the wall of the second receiving slot 24. In the direction in which the free end 41 moves away from the hinged end 42, a gap 50 is defined between the free end 41 and the second receiving slot 24. This gap 50 facilitates the user's application of force to the free end 41, thereby enabling the rotating plate 40 to be rotated out of the second receiving slot 24 more quickly, improving operational convenience.
