[0020] 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.

[0021] The vehicle-mounted wireless charging module of the present invention has a housing space composed of an upper shell 5 and a lower shell 9, and the housing space is used to place wireless charging components such as a coil assembly 3. It also has an interior panel 1 located above the upper shell 5. In practical applications, the interior panel 1 is the interior panel of the vehicle, and the device to be charged is directly placed on the interior panel 1. The upper shell 5 and the lower shell 9 can be fixed with screws 6. When fixing with the interior panel 1, screws 6 can be used together.

[0022] The surface of the interior panel 1 is divided into a raised portion 1a and a sunken portion 1b. When the device to be charged, especially a mobile phone, is placed on the interior panel 1, the protruding camera is located in the sunken portion 1b, and the rest of the body is in the raised portion 1a, making the placement more stable and the alignment of the receiving coil and the coil assembly 3 (transmitting coil) better. Of course, this means that the position of the coil assembly 3 in the accommodating space corresponds to the raised portion 1a. The height difference between the raised portion 1a and the sunken portion 1b is 2mm-8mm, preferably 3mm-5mm.

[0023] A magnet assembly 2 is provided in the accommodation space, on the upper surface of the upper shell 5, or on the lower surface of the interior panel 1. The position of the magnet assembly 2 corresponds to the protrusion 1a. In short, the magnet assembly 2 can be located anywhere between the coil assembly 3 and the interior panel 1. The purpose is to attract the device to be charged, especially an Apple mobile phone.

[0024] At least the sinking part 1b is formed with a vent 11. A mounting groove 12 is formed on the back of the raised part 1a, and the magnet assembly 2 is located in the mounting groove 12. A limiting protrusion is formed on the upper surface of the upper shell 5 for supporting and limiting the magnet assembly 2.

[0025] The accommodation space also includes: a coil printed circuit board assembly 4, which is electrically connected to the coil assembly 3; a shielding cover 7, which is located below the coil assembly 3; and a main printed circuit board assembly 8, which is located below the shielding cover 7. A fan assembly 10 is also provided, which is located outside the lower shell 9. The fan assembly 10 has an air duct pointing to the interior panel 1. The fan assembly 10 is fixed to the lower shell 9 by screws 11.

[0026] The raised portion 1a and the sunken portion 1b of the interior trim panel 1 can be in various forms.

[0027] One solution is that the sunken portion 1 b extends from the top side to the rear side of the interior trim panel 1 , and the length thereof is less than or equal to half the length of the interior trim panel 1 .

[0028] Another solution is that the sunken portion 1 b is located at the top and rear sides of the interior trim panel 1 , and the raised portion 1 a is located in the middle area of ​​the interior trim panel 1 .

[0029] Another solution is that the raised portion 1a is located in the middle area of ​​the interior panel 1 to form a platform, and the raised portion 1a is surrounded by a sunken portion 1b. The platform can be a cylinder or other shapes. Figure 5 An optional structure is shown, where the platform formed by the raised portion 1a is an irregular platform. It should be understood that the purpose of the raised portion 1a is to support the device to be charged (mobile phone), so the specific shape is not limited.

[0030] The above three solutions are optional implementation methods. The common point is that the cooperation between the sinking part 1b and the protruding part 1a can meet the placement of the mobile phone. The protruding camera of the device to be charged is located in the sinking part 1b to ensure the overall stability. The first method is easy to manufacture, but there are requirements for the direction of the mobile phone when it is placed. In the latter two solutions, the direction of the mobile phone placement is more flexible.

[0031] In addition, a fence 13 can be provided on the periphery of the interior trim panel 1, which can not only facilitate the positioning of the device to be charged when it is placed, but also prevent the device to be charged from falling off when the vehicle turns. Figure 1 and Figure 3 As shown, the enclosure 13 is provided at least on three sides of the interior trim panel 1. On the side where the enclosure 13 is not provided, a limiting protrusion 14 may be provided.

[0032] This solution adopts a relatively low cost and cleverly hides the magnet assembly 2 under the interior panel 1 through structural innovation. It solves the problem of interior aesthetics very well. At the same time, a vent is used in the sinking part 1b, which has a hidden effect, is beautiful and has good heat dissipation performance.

[0033] By designing the structure of the raised portion 1a and the sunken portion 1b, the interference with the mobile phone camera is cleverly avoided. At the same time, a mounting groove is provided on the back of the interior trim (raised portion 1a) for mounting the magnet assembly 2, replacing the common practice in the industry of raising the magnet assembly on the surface of the interior trim panel.

[0034] Most current wireless charging modules for cars take about 180 minutes or even longer to charge an Apple phone from 0 to 100%. This patented product can shorten that time to about 125 minutes, greatly improving the user's charging experience. Table 1 below shows the charging data of this patented product, taking the iPhone 14 Pro as an example.
