Description

Technical Field

[0001] The utility model relates to the technical field of magnetic wireless charging accessories, and more specifically, to a magnetic wireless charging air-cooling module. Background Art

[0002] With the development of technology, the use of electronic devices such as mobile phones and tablets has gradually increased. In order to ensure that these electronic devices have sufficient power for daily use, they often need to be equipped with chargers. With the maturity of wireless charging technology, magnetic power banks have been widely used. By setting magnets and coils inside the power banks, magnetic adsorption and wireless charging functions of electronic devices are realized.

[0003] However, as we all know, the efficiency of wireless charging is greatly affected by the heating of the coil. The heating of the coil will seriously affect the efficiency of wireless charging. The greater the charging power, the more serious the heating of the coil, which will further affect the charging efficiency of the coil. This makes it impossible for existing magnetic power banks to achieve high-power charging. In order to cool the magnetic coil as much as possible, additional heat dissipation devices are added to existing magnetic power banks. For example, a water cooling structure is installed in the magnetic power bank to cool the coil by heat transfer. However, the cooling speed of the water cooling method is too slow to meet people's needs. For example, a fan is installed for the coil, and the wind force of the fan is used to blow air to the coil to blow out the heat from the coil. However, the blowing method causes the heat of the coil to be more dispersed, and it is not possible to cool it efficiently.

[0004] In existing magnetic power banks that use fan structures for heat dissipation, the fan assembly is often mounted directly on the power bank's casing, aligning the fan assembly with the coil inside. Alternatively, the fan assembly is first mounted on the casing, and then the coil is secured to the fan assembly. Regardless of the structure, assembly is challenging and a complete coil heat dissipation module cannot be formed.

[0005] The above defects deserve improvement. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the utility model provides a magnetic wireless charging air-cooling module, which installs the magnetic wireless charging component and the fan component on the base to form a complete magnetic wireless charging air-cooling module, improves the heat dissipation efficiency through air cooling, and improves the heat dissipation efficiency of the coil by absorbing heat and blowing it out.

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0037] like Figures 1 to 10 As shown, in order to solve the defects of high coil heating, poor heat dissipation and low efficiency of traditional heat dissipation structure in existing magnetic wireless charging, the present invention provides a magnetic wireless charging air cooling module, which integrates a base 10, a magnetic wireless charging component 20 and a fan component 30, so that the three are integrated into a complete module, which is convenient for direct installation inside the magnetic power bank and easy assembly. Example

[0038] like Figures 1 to 6 As shown, a magnetic wireless charging air-cooling module includes a base 10, a magnetic wireless charging component 20, and a fan component 30. The magnetic wireless charging component and the fan component 30 are mounted on the base 10 and assembled into the wireless charger through the base 10. In this utility model, the base 10 serves as an integrated matrix for the magnetic wireless charging component 20 and the fan component 30, allowing the three to form a complete module. The module can then be manufactured and assembled as a whole, ensuring the module's integration and convenient installation.

[0039] The air inlet of the fan assembly 30 faces the heat dissipation hole, which is used to collect and blow out the heat inside the magnetic wireless charging assembly 20 and the wireless charger. Specifically, the fan assembly 30 includes a shell and a turbo fan installed in the shell. Through the use of the turbo fan, the heat inside the magnetic power bank and the heat generated by the coil can be absorbed, concentrated, and discharged, thereby improving the efficiency of heat discharge. The coil of the present invention can be a charging coil for charging external electronic devices; the coil of the present invention can also be a bidirectional coil, which can not only charge external electronic devices but also accept wireless charging from an external power source.

[0040] In this embodiment, the magnetic wireless charging assembly 20 includes a coil 21, a magnetic plate 22, and a magnet 23. The coil 21 is located on the magnetic plate 22, and the coil 21, magnetic plate 22, and magnet 23 are directly mounted on the base 10. For example, the coil 21, magnetic plate 22, magnet 23, and base 10 can be bonded together using heat dissipation adhesive, which does not affect the stability of the assembly and facilitates heat dissipation.

[0041] To enhance the heat dissipation of coil 21, in this embodiment, magnetic plate 22 includes a magnetic plate body 221. One side of magnetic plate body 221 contacts coil 21, while the other side is concave to form a plurality of magnetic plate channels 223 that increase the heat dissipation area and provide airflow. Preferably, magnetic plate channels 223 are in the form of a plurality of spaced-apart circular rings that conform to the winding direction of coil 21, thereby facilitating heat dissipation.

[0042] like Figure 5 As shown, in this embodiment, the base 10 includes a base body 11, and the base body 11 is provided with a mounting slot 13 for mounting a magnetic wireless charging component 20, and the mounting slot 13 is provided with heat dissipation holes corresponding to the magnetic wireless charging component 20. Specifically, the mounting slot 13 includes a coil slot and a magnet slot. The coil 21 is provided in the coil slot, and the coil slot is provided with a hole corresponding to the position of the coil 21. The magnet 23 is provided in the magnet slot, and the magnet slot is provided with a magnet heat dissipation hole 131 corresponding to the position of the magnet 23. Among them, the middle part of the mounting slot 13 is provided with a base hole 12, and the base hole 12 corresponds to the position of the coil 21, so that the base hole 12 serves as a hole for heat dissipation of the coil 21.

[0043] The mounting slot 13 is flat on the surface of the base body 11, and an air outlet channel 14 is provided on the side of the base body 11. The air inlet of the fan assembly 30 faces the air outlet channel 14. Through the design of this structure, the heat generated by the coil 21 and the heat inside the magnetic power bank can be blown out through the hole 12 in the base, the turbo fan, and the air outlet channel 14; the heat of the magnet 23 and the heat inside the magnetic power bank can be blown out through the magnet heat dissipation hole 131, the turbo fan, and the air outlet channel 14.

[0044] In this embodiment, the magnet slot is fan-shaped, so that the magnet slot forms a gap of not less than 30° at the outlet position of the coil 21. This design can reduce the rectangular design of the base 10. Compared with the square design, it saves more space occupied by the magnetic wireless charging air cooling module.

[0045] Preferably, a magnetic plate middle hole 222 is provided in the middle of the magnetic plate 22, and the center of the magnetic plate middle hole 222 corresponds to the center of the coil 21 and the center of the base middle hole 12 respectively, so that the three can form a heat dissipation path.

[0046] Preferably, a wire outlet 15 is provided on the base body 11 for routing the wires from the coil 21 in the magnetic wireless charging assembly 20. The wire outlet 15 is recessed relative to the surface of the base body 11, allowing the wires from the coil 21 to be routed through the wire outlet 15. This reduces the thickness of the entire structure and prevents wear on the coil 21 after the module is installed.

[0047] On the one hand, the present invention uses a turbofan to concentrate heat from various parts and then blow it out, achieving a faster cooling rate than traditional water cooling, semiconductor cooling fins, and air cooling. On the other hand, the present invention also increases the convenience of the entire module production and assembly through an integrated installation method. Example

[0048] like Figure 7 As shown, unlike the first embodiment, in this embodiment, the magnet slot is in a circular ring shape, which can be suitable for a structure of a magnet 23 that is closer to a circle, and can be suitable for application scenarios such as electronic products with adjustable magnetic attraction angles and more magnets 23 in electronic products.

[0049] Of course, in order to facilitate the wire outlet of the coil 21 , the magnet 23 in this embodiment does not enclose a complete ring, but leaves a gap at the wire outlet position of the coil 21 , and the gap corresponds to the position of the wire outlet 15 of the base 10 .

[0050] Preferably, in order to increase the heat dissipation effect of the magnet 23 and the coil 21 at the coil outlet position and further increase the heat dissipation channel, in this embodiment, the magnet slot is provided with an auxiliary hole 16 at the coil outlet position, and the auxiliary hole 16 is connected to the above-mentioned notch and outlet port 15. Example

[0051] like Figures 8 to 10 As shown, different from the first embodiment, the base hole 12 set in the middle of the base body 11 in this embodiment does not completely correspond to the position of the coil 21, but the base hole 12 only corresponds to the position of the middle hollow part of the coil 21.

[0052] In this embodiment, the mounting slot 13 includes a magnet slot, the magnet 23 is arranged on the magnet slot, and the magnet slot is provided with a magnet heat dissipation hole 131 corresponding to the position of the magnet 23. The mounting slot 13 also includes a coil slot, and the coil slot is provided with a hole corresponding to the position of the coil 21. Specifically, the base body 11 is concave at a position corresponding to the coil slot, and the coil 21 is arranged on the coil slot, forming a plurality of base channels 132, the base channels 132 corresponding to the position of the coil 21, and the base center hole 12 is located in the middle of the base channel 132; the base channel 132 is provided with a penetrating coil heat dissipation hole 133, so that the coil heat dissipation hole 133 serves as a hole for dissipating heat from the coil 21.

[0053] Preferably, the base channel 132 corresponds to the protrusion of the magnetic plate channel 223 in the magnetic plate 22, so that the protrusion of the magnetic plate channel 223 is inserted into the base channel 132. The base channel 132 is annular, and the coil heat dissipation hole 133 is fan-shaped. The coil heat dissipation holes 133 are arranged in the base channel 132 at intervals, so that the base channel 132 and the coil heat dissipation holes 133 are connected, and the heat generated by the coil 21 can be dissipated through the magnetic plate channel 223, the base channel 132, and the fan. The base channel 132 and the magnetic plate channel 223 cooperate with each other to form a heat flow channel, which increases the airflow speed and the heat dissipation area, further enhancing the cooling effect.

[0054] The different structures of the above three embodiments are only schematically illustrated. Without violating the structural principles, the characteristics of each embodiment can also be cross-applied to each other to achieve a combination of multiple technical effects.

[0055] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.

[0056] The above is an exemplary description of the present utility model patent in conjunction with the accompanying drawings.

As long as various improvements are made using the method concept and technical solution of the present utility model patent, or the concept and technical solution of the present utility model patent are directly applied to other occasions without improvement, they are all within the scope of protection of the present utility model.
