[0015] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are only used to explain the present application, and cannot be interpreted as a limitation on the present application.
[0016] The present application provides a vehicle-mounted wireless charging module, referring to Figure 1 It comprises an upper shell 4, a lower shell 7, a fan 8 and a charging assembly. The charging assembly is installed between the upper shell 4 and the lower shell 7, and the specific structure will be described below.
[0017] A first protruding portion 71 is formed on the lower shell 7 towards the upper shell 4, and a mounting cavity is formed on the back of the first protruding portion 71 for mounting the fan 8, which can be fixed by screws 9. Referring to Figure 2 The lower shell air duct 72 is provided on the first protruding portion 71 and communicates with the mounting cavity. The specific position of the lower shell air duct 72 should be set according to the requirements, such as the embodiment shown in the figure, which is set on one side of the first protruding portion 71.
[0018] The structure of the first protruding portion 71 is not limited to a specific shape, as long as the mounting cavity at the bottom can meet the installation of the fan 8.
[0019] In combination Figure 3 A second protruding portion 41 is formed on the upper shell 4, and an upper shell air duct 42 is formed on the second protruding portion 41, which is exposed from the surface of the upper shell 4. The upper shell air duct 42 and the lower shell air duct 72 are in communication, and the airflow blown by the fan 8 can pass through the two air ducts.
[0020] The top of the second protruding portion 41 can be hollow, and in some embodiments, a top cover 1 can be covered on the second protruding portion 41, and the top cover 1 has a top cover air duct. Preferably, the top cover 1 is rotatably connected with the second protruding portion 41, and by rotating the top cover 1, the top cover air duct can be selectively communicated with the upper shell air duct, or the two can not be communicated. During the wireless charging process, the two are communicated, so that the airflow of the fan 8 can be blown out from the top cover air duct to cool the charging mobile phone. Alternatively, the two can not be communicated to avoid pollution by foreign matter, dust, etc.
[0021] The outlet of the upper shell air duct 42 is located on the outer peripheral wall of the second protruding portion 41, that is, the airflow can be blown out from above the top surface of the upper shell 4, which is exactly the bottom when the mobile phone is wirelessly charged, that is, the position with the highest heat, thereby providing better cooling effect.
[0022] The second protruding portion 41 can also be a closed top without being hollowed out. Similarly, the top of the first protruding portion 71 can also be hollowed out or not hollowed out. The top of the first protruding portion 71 is not higher than the second protruding portion 41. Generally, the top of the first protruding portion 71 is below the upper shell 4.
[0023] Preferably, the coil assembly 2, the shielding cover 5 and the PCBA assembly 6 are also included. These can be part of the charging assembly. The shielding cover 5 and the PCBA assembly 6 are sequentially arranged between the upper shell 4 and the lower shell 7; and they respectively have a through hole for the first protruding portion 71 to pass through; the coil assembly 2 is located between the upper shell 4 and the lower shell 7 and connected with the PCBA assembly 6. The coil assembly 2 can be located at the top of the first protruding portion 71. It can be understood from here that the shape of the first protruding portion 71 can achieve the installation of the coil assembly 2, and the specific structure is not limited. The first protruding portion 71 can be too high to position the coil assembly 2, so that it can meet the distance requirements of the mobile phone wireless charging.
[0024] The second protruding portion 41 has a mounting groove for mounting the magnet assembly 3, which is used to attract the mobile phone that needs to be wirelessly charged. In addition to being used to mount the magnet assembly 3, the second protruding portion 41 can also structurally raise the position of the mobile phone, so that there is a certain space between the bottom of the mobile phone and the upper shell 4, and the airflow blown out by the top cover air duct can flow through this space, achieving better cooling effect. Referring to Figure 4 , the arrow in the figure is the direction of the airflow.
[0025] In some embodiments, the fan 8 adopts an axial flow fan, which has larger air volume and lower noise compared with the centrifugal fan used in general vehicle-mounted wireless charging modules. It can better improve the active cooling performance while also better balancing the overall vehicle noise comfort.
[0026] Preferably, the upper shell 4 and the lower shell 7 are fixed by buckles, reducing the number of screws used, reducing the installation process, and saving labor costs.
[0027] Currently, the conventional vehicle-mounted wireless charging product takes about 180 minutes or even longer to charge an iPhone from 0 to 100%. Through the present scheme, the active cooling can shorten the time to about 105 minutes, greatly improving the user's charging experience. Taking the Iphone 16pro as an example, the following Table 1 is the actual measurement data:
[0028] Table 1

[0030] The above describes the structure, features and effects of the present application according to the embodiments shown in the drawings. The above description is only the preferred embodiments of the present application, but the present application is not limited by the drawings. Any changes or modifications made in accordance with the concept of the present application, or equivalent embodiments with equivalent changes, are still within the scope of the present application.
