[0002] With the development of wireless charging technology, wireless chargers are becoming more and more popular among people. Since the wireless charging module and the IC module on the circuit board of the wireless charger generate a large amount of heat, and traditional wireless chargers usually only have ventilation holes for passive heat dissipation, it is easy for the wireless charger to generate heat during use, which significantly affects the charging rate. For this reason, people have added components such as fans, semiconductor refrigeration chips, and radiators to the wireless charger to achieve the active heat dissipation function, such as a vehicle-mounted wireless charger disclosed in Patent CN214707263U. However, current such wireless chargers generally come with a fixed bracket for fixing in the vehicle or on the table, which makes it impossible to switch the bracket.

[0008] Preferably, there are 3-6 clips, and the number of card feet is the same as that of the clips, which are distributed in a triangular, cross or star shape.

[0009] Further, a ring frame is installed on the bottom cover through a hinge structure of a rotating shaft. After being folded, the ring frame is embedded in the bottom cover, and an included angle is formed between the unfolded ring frame and the bottom cover.

[0010] Preferably, the elastic member is in the shape of a button and protrudes out of the installation groove of the locking seat after popping out.

[0011] In the utility model, by arranging clips in the docking holes at the bottom of the wireless charging module, arranging card feet and elastic members on the bracket, after the card feet are inserted into the docking holes, the bracket is rotated so that the card feet are opposite to the clips, and after the bracket is released, the card feet and the clips will be clamped with each other under the elastic force of the elastic member, thereby playing a role in fixing the bracket. In this way, not only can the switching of the bracket be realized to adapt to different application scenarios, but also the operation of loading and unloading the bracket is very convenient and fast.

Detailed Description of the Invention

[0018] In this embodiment, refer to Figures 1 - 5, the active heat dissipation wireless charging device includes a wireless charging module 1 and a bracket 3. A docking hole for connecting the bracket 3 is provided at the bottom of the wireless charging module 1; several latches 21 protruding inward are provided on the hole wall of the docking hole, and gaps are formed between adjacent latches 21 to form an insertion port 22; A locking seat 33 is installed at one end of the bracket 3 opposite to the wireless charging module 1. An installation groove 35 is provided in the locking seat 33, and an elastic member 4 is installed in the installation groove 35; several card feet 34 are provided on the periphery of the locking seat 33. The width of the card feet 34 is smaller than the width of the insertion port 22, so that the card feet 34 can pass through the insertion port 22 and be inserted into the docking hole. After the card feet 34 pass through the insertion port 22 and are inserted into the docking hole, by rotating the bracket 3, the card feet 34 are made to face the latches 21. At this time, the bracket 3 is released, and under the elastic force of the elastic member 4, the bracket 3 is pushed outwards, so that the card feet 34 and the latches 21 can be clamped with each other, realizing the assembly and fixation of the bracket 3 and the wireless charging module 1.
