[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Referring to Figures 1 - 5 , an embodiment provided by the present invention: A quick-disassembly wireless charger with a heat dissipation function, including a main body 1, the main body 1 includes a housing 2 and a PCB main board 9, a wireless charging coil 11 disposed inside the housing 2, and a soft rubber sleeve 20 sleeved outside the housing 2. The external soft rubber sleeve 20 plays a buffering role through its own deformable ability, provides a certain protective effect for the housing 2, and at the same time plays a heat insulation role to avoid scalding due to excessive temperature. Fixing mechanisms 5 are disposed on opposite sides of the housing 2. The main body 1 further includes a clamping assembly detachably connected to the fixing mechanisms 5. The clamping assembly is used for clamping and fixing a mobile phone, and the fixing mechanisms 5 are used for quickly installing and disassembling the clamping assembly, which is very convenient to use.

[0041] In some embodiments, as shown in Figure 2 and Figure 5As shown, the main body 1 further includes a semiconductor heat dissipation component 7. The semiconductor heat dissipation component 7 includes a heat sink 71 and a refrigeration chip 72. The refrigeration chip 72 is electrically connected to the PCB main board 9. In this embodiment, the PCB main board 9 is disposed on the semiconductor heat dissipation component 7. An opening is provided in the middle of the PCB main board 9. There is a refrigeration cavity 30 between the refrigeration chip 72 and the wireless charging coil 11. The refrigeration cavity 30 is opened on the upper shell 21. The wireless charging coil 11 is located above the refrigeration cavity 30, and the refrigeration chip 72 is located below the refrigeration cavity 30. Both the refrigeration chip 72 and the wireless charging coil 11 are communicated with the refrigeration cavity 30, forming a cooling and heat dissipation effect on the wireless charging coil 11. The PCB main board 9 is fixedly connected to the lower shell 22. The housing 2 further includes a decorative board 12 disposed above the wireless charging coil 11. The bottom end of the wireless charging coil 11 is in contact with the decorative board 12. The wireless charging coil 11 transmits electric energy through the magnetic field generated between the coils. The energy is coupled between the coils, and a changing electric field is generated through the changing magnetic field to charge the mobile phone. The wireless charging coil 11 is located in the middle of the magnet 10. The magnet 10 can adsorb the mobile phone. When the mobile phone is wirelessly charged, the whole device is adsorbed on the back of the mobile phone, and then the mobile phone in use can be synchronously wirelessly charged. The wireless charging coil 11 is fixed on the upper shell 21. The wireless charging coil 11 penetrates the upper shell 21 and is in contact with the refrigeration chip 72, forming a cooling and heat dissipation effect on the wireless charging coil 11.

[0042] In some embodiments, as shown in the appended Figures 2 - 4 figures, a charging port is provided on the outer side of the housing 2. A charging socket 13 is disposed inside the charging port. The charging socket 13 is electrically connected to the PCB main board 9. The charging socket 13 is used to charge the entire device. The semiconductor heat dissipation component 7 is disposed inside the housing 2. The refrigeration chip 72 is fixedly connected to and in contact with the heat sink 71. The refrigeration chip 72 includes an N-type semiconductor material and a P-type semiconductor material. The N-type semiconductor material and the P-type semiconductor material are connected. When current passes through the contact point where the P-type semiconductor material and the N-type semiconductor material are connected, a temperature difference will occur. Heat will be absorbed at one contact point and released at the other contact point. Therefore, the refrigeration chip 72 will produce a refrigeration effect on the refrigeration cavity 30. The bottom surface of the heat sink 71 is in contact with the hot surface of the refrigeration chip 72 to help its hot surface dissipate heat effectively, avoiding overheating of the refrigeration chip 72 and resulting in a weakened refrigeration effect. The fixing mechanism 5 includes a slot 54 vertically provided on the housing 2 and having a certain length, and at least one set of card holes 53 are provided on the slot 54.

[0043] In some embodiments, as shown in the appended Figure 1 figures, Figure 3 and appended Figure 4As shown, the clamping assembly includes a long clip 6 and a short clip 51 connected to the long clip 6 by a rotating shaft, and a coil spring 8 is arranged between the long clip 6 and the short clip 51, one end of the coil spring 8 is in contact with the long clip 6, and the other end of the coil spring 8 is in contact with the short clip 51, so that the two groups of long clips 6 form an elastic clamping state. In this embodiment, a soft adhesive sticker is arranged on the inner side of the long clip 6 and the position in contact with the mobile phone to prevent the paint surface of the mobile phone shell from being scratched, wherein the coil spring 8 is sleeved on the rotating shaft, and the elastic force of the coil spring 8 is used to make the two groups of long clips 6 cooperate to clamp and fix the mobile phone, and cooperate with the magnet 10 to play a more stable clamping effect, and the short clip 51 is fixed A clamping block 52 is connected, and the short clip 51 is inserted into the slot 54 of the shell 2. When the clamping block 52 on the short clip 51 is clamped into the clamping hole 53, it is in the installation and fixing state of the clamping component. After the short clip 51 is inserted into the slot 54, the bottom of the slot 54 still has a certain margin backward. During installation, it is only necessary to insert the short clip 51 into the slot 54. Due to the existence of the clamping block 52 and the margin in the slot 54, the short clip 51 will be deformed to a certain extent until the clamping block 52 coincides with the clamping hole 53. The elastic force of the short clip 51 itself will reset it, so that the clamping block 52 is clamped with the clamping hole 53. When they are clamped with each other, the short clip 51 can be installed on the side wall of the shell 2.

[0044] In some embodiments, as shown in the attached Figure 4 As shown, the shell 2 includes an upper shell 21 and a lower shell 22 arranged above the upper shell 21. The bottom of the lower shell 22 is a hollow design. The upper shell 21 and the lower shell 22 are fixed by bolts to facilitate the rapid heat dissipation of the semiconductor heat dissipation component 7. An expansion hole 4 is provided at the center of the bottom of the lower shell 22. The expansion hole 4 can be connected to a screw and fixed to a live broadcast bracket or other expansion brackets or a fixed base, etc., which is convenient for use on a bicycle, a car or a motorcycle, is more stable, and increases its usage scenarios. A display screen 3 is embedded on one side of the expansion hole 4. The display screen 3 is electrically connected to the PCB main board 9 and can display the working status of the display main body, such as charging voltage or current information. The main body 1 also includes a magnet 10 embedded in the shell 2. The magnet 10 is located on the upper surface of the upper shell 21. The magnet 10 is a closed annular structure or a non-closed annular structure. The magnet 10 is used to connect with the magnet or iron sheet on the mobile phone.

[0045] Working principle: By pressing the long clip pieces 6 on both sides, they rotate along the hinge joint with the short clip piece 51, causing the outer ends to expand outwards. At the same time, the coil spring 8 contracts and deforms. At this time, the back of the mobile phone is placed at a position fitting with the decorative plate 12. After releasing the long clip pieces 6, the coil spring 8's restoring force is used to clamp and fix the wide sides of the mobile phone on both sides. With the cooperation of the magnet 10, it becomes more stable, and the mobile phone is charged through the wireless charging coil 11. The cooling piece 72 cools the refrigerating chamber 30, and the cold air in the refrigerating chamber 30 is used to cool down the wireless charging coil 11. The heat on the hot surface of the cooling piece 72 is transferred to the heat sink 71 for dissipation. When it is necessary to disassemble the short clip piece 51 and the long clip piece 6, the block 52 is pressed inwards, causing the short clip piece 51 to deform to a certain extent and making the block 52 disengage from the card hole 53. At this time, the short clip piece 51 can be pulled out for disassembly.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
