[0032] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings. The same reference numerals in the drawings represent components with the same structure or similar structures but the same functions.

[0033] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.

[0034] Figure 1 The figure is a schematic structural diagram of an exemplary implementation of a wireless charging device for an automobile with a heat dissipation structure. Figure 2 This is a schematic diagram of the assembly structure of a car wireless charging device with a heat dissipation structure. Figure 1 and Figure 2 The automobile wireless charging device with a heat dissipation structure includes a sub-instrument panel 10, a wireless charger 20 and a rubber pad 30.

[0035] Reference Figure 1 A heat dissipation opening 11 is formed on the sub-instrument panel 10. The wireless charger 20 is fixed to the inner side of the sub-instrument panel 10. The radiator air outlet 21 of the wireless charger 20 faces the heat dissipation opening 11, so that the air discharged from the radiator air outlet 21 can be discharged upward through the heat dissipation opening 11. Figure 2 The rubber pad 30 can cover the heat dissipation opening 11 on the outer side of the auxiliary instrument panel 10 under the action of gravity.

[0036] Figure 3 The portion of the rubber pad 30 covering the heat dissipation opening 11 is formed with a plurality of through-holes 31 (due to the large number, Figure 3Only one of them is marked in the figure), the air exhausted from the radiator outlet 21 can be exhausted through the heat dissipation opening 11 and the air vent 31, which can not only dissipate the heat of the wireless charger 20, but also dissipate the heat of the mobile phone placed on the rubber pad 30 and being wirelessly charged.

[0037] The automobile wireless charging device with heat dissipation structure provided by the utility model has a large heat dissipation opening 11 on the sub-instrument panel 10, the radiator outlet 21 of the wireless charger 20 faces the heat dissipation opening 11, and the heat dissipation opening 11 is covered by a rubber pad 30 with air holes 31. The mobile phone can be placed on the rubber pad 30 for wireless charging, and the air holes 31 on the rubber pad 30 allow the air discharged from the radiator outlet 21 of the wireless charger 20 to be discharged, ensuring that the wireless charger 20 can effectively dissipate heat. The rubber pad 30 can be removed from the sub-instrument panel 10 at any time to clean smaller items or dust.

[0038] In an exemplary embodiment, referring to Figure 1 and Figure 2 The outer side of the auxiliary instrument panel 10 is recessed to form a charging storage cavity 13, and the charging storage cavity 13 has a bottom surface 14. The bottom surface 14 is usually a flat plane, and the heat dissipation opening 11 is formed on the bottom surface 14. A part of the rubber pad 30 has the same shape as the bottom surface 14 and can completely cover the bottom surface 14. This makes it easy to store mobile phones or other items.

[0039] In the exemplary embodiment, the rubber pad 30 is further formed with a handle portion 38 at the edge. When the rubber pad 30 completely covers the bottom surface 14, the handle portion 38 can be bent away from the bottom surface 14. When the rubber pad 30 is removed from the auxiliary instrument panel 10, the handle portion 38 can be grasped to lift the rubber pad 30 for easy operation.

[0040] In an exemplary embodiment, referring to Figures 1 to 3 The outer side of the sub-instrument panel 10 is concave to form four positioning grooves 12, and the rubber pad 30 is convex on the side facing the heat dissipation opening 11 to form four positioning parts 36. The four positioning parts 36 are embedded in the four positioning grooves 12 one by one to prevent the rubber pad 30 from sliding relative to the sub-instrument panel 10. This ensures that the installation of the rubber pad 30 is more stable. Although the number of positioning grooves 12 and positioning parts 36 is four, they are not limited to this. In other exemplary embodiments, the number of positioning grooves 12 and positioning parts 36 can be adjusted according to actual needs.

[0041] In an exemplary embodiment, referring to Figure 3The rubber pad 30 is raised on one side facing the heat dissipation opening 11 to form four support portions 34. Each support portion 34 has a specific strip-shaped raised structure, so that it can abut against the wireless charger 20 in the heat dissipation opening 11 to prevent the rubber pad 30 from collapsing. Although the number of the support portions 34 is four, it is not limited thereto. In other exemplary embodiments, the number of the support portions 34 can be adjusted according to actual needs.

[0042] Figure 4 for Figure 1 Schematic cross-sectional view of the AA position. Figure 5 for Figure 4 A partial enlarged schematic diagram of position B in the middle. Figure 4 and Figure 5 The rubber pad 30 is raised on the side facing away from the heat dissipation opening 11 to form a plurality of bumps 32, and each bump 32 protrudes from the surface of the rubber pad 30 by 0.3 mm. A mobile phone can be placed on the bumps 32 to form a ventilation gap between the mobile phone and the surface of the rubber pad 30, thereby preventing the mobile phone from blocking the air vent 31 and affecting the heat dissipation effect.
