[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0018] The utility model discloses a vehicle-mounted wireless charging system, see Figure 1 and Figure 2 , which includes: an interior trim panel 2 and a wireless charger 3. The interior trim panel 2 is installed inside the vehicle, and is arranged in a form of high front and low back, and the high front and low back are reflected in the form of a horizontal line angle of 15°-35°. That is, as shown in the figure, the front direction of the vehicle is the front, and the parking space direction is the rear. The front of the interior trim panel 2 has a supporting surface for placing the mobile phone 1, and the bottom of the supporting surface has a bottom baffle 22 for supporting the mobile phone 1. After the mobile phone 1 is placed on the supporting surface, it naturally has an angle of 15°-35° with the horizontal line, and can be supported on the bottom baffle 22.

[0019] A wireless charger 3 is fixedly arranged on the back of the interior panel 2, and the working direction of the wireless charger 3 is toward the supporting surface. The specific structure of the wireless charger 3 will be described below. The working direction mentioned here generally refers to the direction of the transmitting coil 31 of the wireless charger 3, which can satisfy the requirement that when the mobile phone 1 is placed on the supporting surface, the wireless charger 3 can wirelessly charge the mobile phone 1. The center position of the working area of ​​the wireless charger 3 is 70mm-80mm away from the bottom baffle 22. Figure 4 This distance is shown as L in FIG.

[0020] A recessed area is formed on the supporting surface, and an air outlet 21 is formed within the range of the recessed area; the air outlet 21 is connected to the fan assembly 35. The range of the recessed area is generally smaller than the size of the mobile phone 1, and its purpose is to prevent the mobile phone 1 from completely fitting with the supporting surface and affecting the heat dissipation. Therefore, the recessed area is set, and the mobile phone 1 is cooled by the fan assembly 35. The recessed area is rectangular, which is only an example. In practice, it can be made into other shapes according to needs. For example, the same effect can be achieved by realizing the recessed area in an uneven manner, or the guide wing and guide groove for guiding the wind are formed on the supporting surface, which can also be used as the recessed area.

[0021] At the same time, the air outlet 21 is arranged at one end close to the bottom baffle 22 , and when the mobile phone 1 is placed squarely, it is at the bottom of the mobile phone 1 , so that the camera can avoid blocking the air outlet 21 .

[0022] A limiting groove (not shown in the figure) is provided on the bottom baffle 22, and the limiting groove is provided on the side of the bottom baffle 2 facing the supporting surface and is located at the bottom of the bottom baffle 22. The purpose is to make the bottom part of the mobile phone 1 extend into the limiting groove when the mobile phone 1 is placed, so that the position of the mobile phone 1 can be prevented from moving on a bumpy road or when turning.

[0023] like Figure 3 In a preferred embodiment shown, a limiter is provided on the bottom baffle 22, and the limiter has a power arm 25 and a limit arm 24 fixedly connected at an obtuse angle, and a limit ball 23 is provided on the limit arm 24; the connection between the power arm 25 and the limit arm 24 is rotatably provided on the bottom baffle 22.

[0024] When the mobile phone 1 is placed, the bottom of the mobile phone pushes against the power arm 25, so that the limiting arm 24 drives the limiting ball 23 to press down and lock the mobile phone 1 to prevent it from moving.

[0025] The structure of the wireless charger 3 is described in detail below. Figure 4, it has a containing space formed by a lower shell 34 and an upper shell 36, in which there are: a transmitting coil 31, a shielding cover 32, and a main board 33; the transmitting coil 31 is connected to the main board 33, and the shielding cover 32 is located above the transmitting coil 31; a fan assembly 35 is connected to the outside of the lower shell 34. Correspondingly, the lower shell 34 and / or the upper shell 36 form an air duct so that the fan assembly 35 can communicate with the air outlet 21.

[0026] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
