Description

Technical Field

[0001] This utility model relates to the field of wireless charging stand technology, and more specifically, to a foldable wireless charging stand. Background Technology

[0002] Currently, there are many types of foldable wireless charging stands on the market, which can meet the charging needs of smartphones and other mobile devices and are convenient to carry and use. However, the surface of these stands that supports the smartphone is mostly flat. When charging, the back of the smartphone needs to be in full contact with the stand, which makes it difficult for heat to dissipate from the back of the smartphone, resulting in poor heat dissipation and poor charging performance. In subsequent improvements, a charging part with a certain height has been designed on the supporting surface of the stand to provide some heat dissipation space for the back of the smartphone during charging. Although this has a certain heat dissipation effect, the heat dissipation is slow and the heat dissipation efficiency is not high. Existing stands lack a structural layout design for active heat dissipation during the charging of smartphones and other mobile devices. Therefore, there is an urgent need to design a new type of foldable wireless charging stand to solve this problem. Utility Model Content

Obviously, the described embodiments are some, but not all, 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 protection scope of this utility model.

[0024] This utility model embodiment provides a foldable wireless charging stand, such as Figures 1 to 5 As shown, the foldable wireless charging stand includes a first folding part 1, a second folding part 2, and a third folding part 3 connected in sequence. The first folding part 1 is provided with a protruding heat dissipation part 4 and a first magnetic wireless charging part 5, and the heat dissipation part 4 and the first magnetic wireless charging part 5 are at the same height. The heat dissipation part 4 is formed by a support frame 41 and a heat-conducting plate 42. The support frame 41 is located on the upper surface of the first folding part 1, and the heat-conducting plate 42 is parallel to the upper surface of the first folding part 1. A heat dissipation cavity is formed between the heat-conducting plate 42, the support frame 41, and the first folding part 1. The upper surface of the first folding part 1 is also provided with a first miniature silent fan 6, a first temperature sensor 7, and a first microcontroller 8 located in the heat dissipation cavity. The first miniature silent fan 6 and the first temperature sensor 7 are electrically connected to the first microcontroller 8. Several first heat dissipation holes 410 are provided on the four sides of the support frame 41.

[0025] The foldable wireless charging bracket of this utility model embodiment magnetically charges smartphones and other mobile terminals via the first magnetic wireless charging unit 5. At the same time, the back of the smartphones and other mobile terminals comes into contact with the heat-conducting sheet 42. Under the action of the heat-conducting sheet 42, the heat on the smartphones and other mobile terminals can be transferred to the heat dissipation cavity in a timely manner. The first temperature sensor 7 is used to sense the temperature in the heat dissipation cavity. Then, under the control of the first microcontroller 8, the first miniature silent fan 6 is started in a timely manner. Thus, under the coordinated control of the first miniature silent fan 6, the first temperature sensor 7, and the first microcontroller 8, the heat in the heat dissipation cavity is dissipated to the outside through several first heat dissipation holes 410 in a timely manner, thereby improving the heat dissipation efficiency and achieving a better heat dissipation effect.

[0026] It should be noted that the contact area between the back of a smartphone or other mobile terminal and the heat-conducting plate 42 depends on the size of the heat-conducting plate 42, which can be designed and selected according to actual application requirements. This embodiment does not impose specific limitations. As for the temperature threshold parameter requirements, those skilled in the art can design and select them according to actual application requirements.

[0027] Specifically, in this embodiment, the third folding section 3 is provided with a power bank module 31 and a wireless charging module 32, which are horizontally spaced apart from each other.

When charging is needed, the earphone shell with wireless charging functionality is correctly placed in the wireless charging area on the third folding section 3. The power bank module 31 is used to meet the user's power needs, and one side wall of the third folding section 3 is also provided with an interface 30 electrically connected to the power bank module 31. The power bank module 31 may include, for example, a power module, a transformer module, etc., and the power module may be, for example, a battery cell; the wireless charging module 32 may include, for example, a wireless charging coil module. The applications of the power bank module 31 and the wireless charging module 32 are relatively existing, and this embodiment does not impose specific limitations on them.

[0028] Furthermore, in this embodiment, the third folding section 3 is also equipped with a second miniature silent fan 9, a second temperature sensor 10, and a second microcontroller 11. The second miniature silent fan 9 and the second temperature sensor 10 are electrically connected to the second microcontroller 11. A plurality of second heat dissipation holes 301 are provided on all four sides of the third folding section 3. When a power bank module 31 and a wireless charging module 32 are installed in the third folding section 3, the heat inside the third folding section 3 can be dissipated outwards through the plurality of second heat dissipation holes 301 in a timely manner through the coordinated control of the second miniature silent fan 9, the second temperature sensor 10, and the second microcontroller 11, ensuring the normal operation of the power bank module 31 and the wireless charging module 32. The function of the second miniature silent fan 9 is the same as that of the first miniature silent fan 6, the function of the second temperature sensor 10 is the same as that of the first temperature sensor 7, and the function of the second microcontroller 11 is the same as that of the first microcontroller 8; these will not be described in detail here.

[0029] Specifically, in this embodiment, the second folding part 2 is provided with a receiving slot 20, and a second magnetic wireless charging part 21 is provided in the receiving slot 20. The second magnetic wireless charging part 21 is flipped and connected to the receiving slot 20 through a first rotating connecting assembly. The second magnetic wireless charging part 21 can be used to charge the smartwatch. The first folding part 1 and the second folding part 2, as well as the second folding part 2 and the third folding part 3, are rotatably connected through the second rotating connecting assembly. Both the first and second rotating connecting assemblies are, for example, damped pivot assemblies, allowing the first folding part 1 to unfold at a suitable angle relative to the second folding part 2, and the second folding part 2 to unfold at a suitable angle relative to the third folding part 3, thus meeting the corresponding charging needs and providing good support stability.

[0030] It should be noted that the layout design of the magnetic wireless charging module 32 in the first magnetic wireless charging unit 5, the second magnetic wireless charging unit 21, and the wireless charging module 32 in the third folding unit 3 are all relatively existing, and relevant applications in the prior art can be referred to in actual implementation.

[0031] Specifically, in this embodiment, the heat-conducting sheet 42 and the support frame 41 are bonded together with thermally conductive adhesive; the support frame 41 and the first folded part 1 are integrated into a single structure.
