DETAILED DESCRIPTION

[0021] The technical solution of the utility model is described below in conjunction with the accompanying drawings and embodiments.

[0022] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0023] Example 1

[0024] This embodiment is a high-power magnetic wireless charging mobile power supply with autonomous heat dissipation, such as Figure 1 and Figure 2As shown, it includes a shell 14, a battery core 13, a wireless charging coil 3, a heat dissipation part, and an annular magnetic magnet 9. The battery core 13 and the heat dissipation part are respectively located at the two ends of the mobile power supply. The annular magnetic magnet 9 surrounds the wireless charging coil 3 and is located at one end close to the heat dissipation part. The heat dissipation part includes a hidden air inlet 4, an air inlet cavity body 5, a through hole 8 of the circuit board 2, a fan 1, an air outlet cavity body 7 and an air outlet 6. The hidden air inlet 4 is a gap formed between the annular magnetic magnet 9 and the shell 14. The annular magnetic magnet 9 and the wireless charging coil 3 and the circuit board 2 constitute the air inlet cavity body 5. A gap is provided between the fan 1 and the shell 14 to constitute the air outlet cavity body 7. The shell 14 at the air outlet cavity body 7 is provided with an air outlet 6; the fan 1 draws in the outside air through the hidden air inlet 4 and passes through the air inlet cavity body 5, the circuit board 2 and the fan 1 in sequence, enters the air outlet cavity body 7, and is discharged through the air outlet 6 to achieve heat dissipation.

[0025] This embodiment dissipates the heat generated by the PCB circuit board 2 and the wireless charging coil 3 during charging by setting a heat dissipation unit inside the mobile power supply, thereby reducing the heat accumulation inside the mobile power supply, and effectively solving the problem that the existing mobile power supply cannot dissipate heat, resulting in low charging efficiency of electronic products and affecting the life of electronic products. The charging efficiency is improved, the charging time is reduced, the electronic products are protected, and the service life of the electronic products is extended.

[0026] In order to better dissipate heat for the circuit board 2 and reduce the transfer of heat inside the device, the PCB circuit board 2 is provided with a through hole 8, and the through hole 8 is connected to the blade space of the fan 1. The fan 1 draws air at the air inlet through the air inlet, enters the air inlet cavity 5, and then enters the blade space of the fan 1 through the through hole 8 on the PCB circuit board 2, avoiding unnecessary heat transfer caused by excessive detours of wind, and improving heat dissipation efficiency. The air is discharged to the air outlet cavity 7 through the fan 1 and discharged through the air outlet 6.

[0027] For heat dissipation, the air outlet 6 on the housing 14 can be a plurality of arranged small holes or an integral exhaust hole. The air outlet 6 is arranged in an array on multiple surfaces of the housing 14 of the air outlet cavity 7 to enhance heat dissipation efficiency. In this embodiment, the air outlet 6 is preferably arranged on three sides of the mobile power supply, such as Figure 3As shown. Specifically, the mobile power supply of this embodiment forms a hidden air inlet 4 through the gap formed between the annular magnetic magnet 9 and the shell 14. The air inlet opening area of ​​this design is small and belongs to a hidden outlet. On the one hand, it is more beautiful, and on the other hand, it can also prevent foreign objects from falling in. In order to prevent dust, foreign objects, etc. from falling directly into the mobile power supply through the air inlet, affecting the performance of the device or even damaging the device, or affecting the heat dissipation effect, this embodiment is provided with a step on the cross section of the above-mentioned hidden air inlet 4, so that the air inlet presents a structure that gradually enlarges from the inside to the outside. Optionally, the battery cell 13 does not have the hidden air inlet 4 in the projection area on the shell 14, so as to prevent the fresh air from entering too many paths inside the device, resulting in a reduction in the heat dissipation effect, thereby concentrating the heat dissipation structure near the wireless charging coil 3, making the heat dissipation work more centralized and efficient.

[0028] Since the wireless charging coil 3 is mostly circular, in order to better dissipate the heat of the wireless charging coil 3, the present embodiment sets the air inlet around the wireless charging coil 3, which can effectively dissipate the heat of the charging coil from all sides.

[0029] In order to better improve the heat dissipation effect and prevent the cold air in the air inlet cavity 5 from mixing with the hot air in the air outlet cavity 7 to affect the heat dissipation effect, in this embodiment, a first seal 10 is provided between the circuit board 2 and the housing 14 and the wireless charging coil 3 to isolate the air inlet cavity 5 from the air outlet cavity 7. A second seal 11 is provided between the fan 1 and the circuit board 2. Specifically, the first seal 10 and the second seal 11 can be made of materials with sealing properties such as sponge and rubber, and sponge EVA is preferred in this embodiment.

[0030] In order to facilitate charging, improve the stability of the electronic device during charging, and prevent it from slipping and disconnecting the charging or breaking the device, the present embodiment further provides a magnetic positioning magnet 12 next to the magnetic magnet 3 to fix the electronic device and prevent it from slipping. At the same time, it can also find the charging position more quickly without detailed alignment, thereby improving the user experience.

[0031] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0032] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit them. Although the utility model is described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
