[0024] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one skilled in the art that the present application can be practiced in a variety of ways beyond those specifically described in this description, and that the present application is not limited to the specific embodiments described in this description.

[0025] It should be noted that in the present application, unless otherwise defined, all technical and scientific terms used in the specification of the present application have the same meaning as understood by those skilled in the art of the technology to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments of the present application, and are not intended to limit the present application. The term "and / or" used in the specification of the present application includes any and all combinations of one or more related listed items.

[0026] The wireless charging panel and vehicle provided by the present application will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figures 1-2 As shown in the figure, the wireless charging panel comprises a panel base body 1 and a surface layer 2 provided on the panel base body 1, a reversible thermochromic layer 3 is provided in the surface layer 2, and the reversible thermochromic layer 3 displays different colors in different temperature intervals.

[0028] When the mobile phone wireless charging system is started, especially during the charging of the mobile phone, as the mobile phone wireless charging system and the mobile phone generate heat, the color of the reversible thermochromic layer 3 can change with the temperature change of the wireless charging panel, so that the wireless charging panel displays different colors in different temperature intervals, and the person in the vehicle can judge the temperature of the mobile phone wireless charging system through the color change of the wireless charging panel, and quickly identify the overheating risk through the color change, and end the charging operation as soon as the overheating risk is reached, effectively preventing serious accidents caused by overheating.

[0029] At the same time, when the cold air system is configured in the vehicle, it is not necessary to start the cold air system synchronously with the mobile phone wireless charging system, which can avoid the additional energy consumption caused by starting the cold air system in the absence of overheating risk to a certain extent, and it is also not necessary to set an additional temperature sensor to control the start of the cold air system, thereby simplifying the structure and reducing the cost.

[0030] Therefore, the wireless charging panel of the utility model, through setting reversible thermochromic layer 3 in surface layer 2, makes wireless charging panel display different colors in different temperature intervals, and the person in the vehicle can judge the temperature of the mobile phone wireless charging system through the color change of the wireless charging panel, so as to quickly indicate the overheating phenomenon of the mobile phone wireless charging system, remind the person in the vehicle to disconnect the mobile phone wireless charging system to avoid serious accidents caused by overheating, and the structure is simple and the cost is low.

[0031] In the utility model, as shown in Figure 2 The reversible thermochromic layer 3 can be arranged in the charging area 4 or the non-charging area.

[0032] Considering that the temperature of different areas of the surface layer 2 changes differently during the charging of the mobile phone, compared with other areas, the charging area 4 heats up the fastest due to direct contact with the mobile phone, and the different temperature change rates will affect the color change rate of the reversible thermochromic layer 3, thereby affecting the judgment rate of the temperature of the wireless charging panel by the person in the vehicle. Therefore, in the utility model, the reversible thermochromic layer 3 is preferably located in the charging area 4. By arranging in this way, the temperature of the wireless charging panel can be quickly and accurately obtained during the charging of the mobile phone due to the fastest temperature rise of the charging area 4, thereby providing fast and accurate temperature indication for the person in the vehicle.

[0033] In an embodiment, the charging area 4 of the surface layer 2 is provided with a groove matched with the reversible thermochromic layer 3. By arranging in this way, the reversible thermochromic layer 3 is embedded in the groove of the surface layer 2, as shown in Figures 1-3 The color change of the reversible thermochromic layer 3 can be more clearly seen.

[0034] In another embodiment, the surface layer 2 is provided with a through groove, and the reversible thermochromic layer 3 is arranged in the reversible thermochromic layer 3 through the through groove.

[0035] It should be noted that the material of the reversible thermochromic layer 3 in the utility model includes a reversible thermochromic material, which shows no color at low temperature, and the color starts to change when the ambient temperature rises to the critical color-changing temperature, and the changed color is maintained within a certain temperature interval, which is called the color development temperature interval. Different reversible thermochromic materials have different critical color-changing temperatures, color development temperature intervals and displayed colors.

[0036] In an embodiment, the reversible thermochromic material selected by the utility model is a micron-sized spherical transparent material coated heat-absorbing electron transfer type organic compound, which has no biological toxicity and is suitable for automotive interior parts.

[0037] In order to better judge the temperature change of the mobile phone wireless charging system through the color change of the wireless charging panel, and better indicate the overheating risk level of the mobile phone wireless charging system, the reversible thermochromic layer 3 in the utility model includes two or more than two interval arranged color-changing layers, each color-changing layer has a different color development temperature interval and displays a different color. It can be understood that each color-changing layer has a different critical color-changing temperature and displays a different color in the colored state.

[0038] Further, the interval distance between adjacent color-changing layers is 1mm-2mm. It can be understood that the interval distance between adjacent color-changing layers can be any value between 1mm-2mm, specifically, the interval distance between adjacent color-changing layers includes but is not limited to 1mm, 1.1mm, 1.3mm, 1.5mm, 1.6mm, 1.8mm, 2mm. In this way, the color change of different color-changing layers can be better distinguished.

[0039] It can be understood that the reversible thermochromic layer 3 includes two interval arranged color-changing layers in the surface layer 2, or three interval arranged color-changing layers in the surface layer 2, or four interval arranged color-changing layers in the surface layer 2, and each color-changing layer can represent a risk level. In the utility model, in order to avoid the discomfort caused by multiple color changes, the utility model preferably has three color-changing layers.

[0040] Specifically, as shown in FIG. 1, the surface layer 2 is provided with a through groove, and the reversible thermochromic layer 3 is arranged in the reversible thermochromic layer 3 through the through groove. Figures 1-4As shown, the reversible thermochromic layer 3 includes the first color-changing layer 31, the second color-changing layer 32 and the third color-changing layer 33 which are arranged in the surface layer 2 in sequence, the color-changing temperature intervals of the first color-changing layer 31, the second color-changing layer 32 and the third color-changing layer 33 are different, and the display colors are different.

[0041] Further, the color-changing temperature interval of the first color-changing layer 31 is 30-40℃, the display color is from colorless to blue, the color-changing temperature interval of the second color-changing layer 32 is 40-50℃, the display color is from blue to yellow, and the color-changing temperature interval of the third color-changing layer 33 is 50-60℃, the display color is from yellow to red.

[0042] It can be understood that the critical color-changing temperature of the first color-changing layer 31 is 30℃, the critical color-changing temperature of the second color-changing layer 32 is 40℃, and the critical color-changing temperature of the third color-changing layer 33 is 50℃. Therefore, when the temperature of the surface layer 2 of the wireless charging panel is lower than 30℃, the surface layer 2 of the wireless charging panel displays the original color; when the temperature of the surface layer 2 of the wireless charging panel is 30-40℃, the first color-changing layer 31 changes color, and the display color is blue, at this time, it can be determined that the overheat risk level of the mobile phone wireless charging system is low; when the temperature of the surface layer 2 of the wireless charging panel is 40-50℃ and greater than 40℃, the blue displayed by the first color-changing layer 31 disappears, the second color-changing layer 32 changes color, and the display color is yellow, at this time, it can be determined that the overheat risk level of the mobile phone wireless charging system is medium; when the temperature of the surface layer 2 of the wireless charging panel is 50-60℃ and greater than 50℃, the yellow displayed by the second color-changing layer 32 disappears, the third color-changing layer 33 changes color, and the display color is red, at this time, it can be determined that the overheat risk level of the mobile phone wireless charging system is high, and the person in the vehicle stops the charging operation according to the above indication. When the temperature of the surface layer 2 of the wireless charging panel is lower than 30℃, the surface layer 2 of the wireless charging panel returns to the original color.

[0043] Therefore, in the utility model, when the reversible thermochromic layer 3 includes the first color-changing layer 31, the second color-changing layer 32 and the third color-changing layer 33 which are arranged in the surface layer 2 in sequence, the surface area of the wireless charging panel is arranged as a temperature reminding area, and the color-changing temperature interval is wide, when the temperature of the wireless charging panel increases from 30-60℃, the temperature reminding area gradually displays the above-mentioned four colors, reminding the person in the vehicle of the temperature of the wireless charging panel, that is, the corresponding overheat risk level, and the person in the vehicle determines whether the mobile phone wireless charging system needs to be disconnected according to the indicated overheat risk level, so that the normal use of the mobile phone wireless charging system and the charging safety of the mobile phone are better ensured.

[0047] Optionally, the surface layer 2 is a silicone rubber layer, and the Shore hardness of the silicone rubber layer is 50-60 degrees, preferably 55 degrees. Compared with conventional thermoplastic elastomer materials, the heat resistance of the silicone rubber layer can reach 200 DEG C, and has excellent soft touch and wear resistance and other properties, which can significantly improve the durability of the wireless charging panel and reduce the risk of overheating aging.

In this way, the color visibility after color change can be better guaranteed.

[0050] As shown in Figure 1 The adhesive layer 5 is arranged between the panel base body 1 and the surface layer 2, and the panel base body 1 and the surface layer 2 are connected through the adhesive layer 5.
