[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] Embodiment 1

[0033] This embodiment relates to a thermochromic ceiling, which can enhance the decoration and atmosphere creation effect of the automobile ceiling; an exemplary structure thereof is as follows Figure 1 and Figure 2 shown.

[0034] In general, the thermochromic ceiling includes a frame 1, a fabric 2 laid on the frame 1, and a heating unit 3 arranged inside the fabric 2. The heating unit 3 is used to control the temperature of the fabric 2, and the surface of the fabric 2 is provided with a thermochromic coating, and the color of the fabric 2 changes with the temperature of the fabric 2.

[0035] There are many choices for the material of the fabric 2. Specifically, the fabric 2 of this embodiment can be any one of knitted fabric, leather, and suede. The fabric 2 is made of the above materials, which is convenient to obtain and process, and has good decorative effect and durability.

[0036] The coating of the thermochromic coating can be applied in the following scheme. The thermochromic material is uniformly mixed into the color paste to prepare the dye of the thermochromic coating of this embodiment, and preferably an adhesive is added thereto, and then the thermochromic coating is disposed on the surface of the fabric 2 by a coating or printing process. The thermochromic dye is formed by adding the thermochromic material to the color paste containing the adhesive. The dye containing the thermochromic material absorbs the energy of light under the set temperature condition, and the electrons of the thermochromic material are transferred back and forth between the electron donor and the electron acceptor, and the molecular structure changes, thereby causing the color change, and achieving the effect that the color of the thermochromic coating changes with the temperature. The above-mentioned thermochromic coating with the addition of an adhesive not only has the performance of temperature-controlled color change, but also is easy to be coated or printed on the fabric 2, ensuring the adhesion firmness of the thermochromic coating on the fabric 2.

[0037] In addition, the thermochromic coating can be applied to the entire surface of the fabric 2 in a single color; thus, as the temperature of the fabric 2 changes, the overall color of the fabric 2 changes accordingly, such as Figure 3 Alternatively, the thermochromic coating can also be printed on a set area on the fabric 2 based on a set pattern, so that as the temperature of the fabric 2 increases, the pattern appears on the fabric 2, as shown in FIG. Figure 4 shown.

[0038] When the thermochromic coating adopts a single color change mode, the thermochromic dye is simple to prepare and can be directly applied to the fabric 2 to form a thermochromic coating. When the fabric 2 is affected by the external temperature or reaches the range of 31°C to 37°C under the control of the heating unit 3, the overall color of the fabric 2 will change, and the preset color of the thermochromic dye will appear within 8s to 13s.

[0039] When the thermochromic coating adopts a composite color combination color change mode, a thermochromic coating is formed by printing a plurality of preset color thermochromic dyes on the fabric 2 based on a set pattern, which can present rich colors and patterns on the fabric 2. When the fabric 2 is affected by the external temperature or reaches the range of 41°C to 47°C under the control of the heating unit 3, the color appearance of the fabric 2 will change, and the set pattern will appear on the fabric 2 within 8s to 13s, further enhancing the atmosphere creation effect and interest of the car roof. After the temperature change, the pattern will be more three-dimensional, enhancing the visual refinement of the car roof.

[0040] In the actual production process, the distance between the pattern printed on the fabric 2 and the edge of the car roof should be more than 3 cm to avoid the folding of the component structure at the edge of the car roof and the edge of the fabric 2, which will affect the overall effect of the pattern and reduce the exquisiteness of the product. For the frame 1, a PU board ceiling body produced by a wet process can be used.

[0041] In this embodiment, if Figure 4 As shown, the fabric 2 is provided with a raised structure, and at the same time, the thermochromic coating is printed on the raised structure based on a set pattern, and the heating unit 3 is arranged corresponding to the raised structure. Preferably, the fabric 2 can be divided into a plurality of color-changing regions, and each color-changing region is formed by setting an embroidery pattern layer based on different patterns; the thermochromic coating is printed on the embroidery pattern layer. Specifically, in this embodiment, the fabric 2 is divided into four color-changing regions, namely, the first color-changing region 100, the second color-changing region 200, the third color-changing region 300 and the fourth color-changing region 400, and embroidery pattern layers and thermochromic coatings of different patterns are arranged in each color-changing region. When the heating unit 3 heats the fabric 2 and the fabric 2 is heated to the set temperature, due to the presence of the raised structure and the thermochromic coating thereon, each color-changing region of the fabric 2 presents a three-dimensional and colorful pattern, which can further enhance the temperature control color richness and decorative effect of the car roof. Moreover, an embroidery pattern layer may be added to the fabric 2, and when the embroidery pattern is heated, the pattern presented by the thermochromic coating is coordinated and coordinated, which can further enhance the decorative effect of the automobile roof.

[0042] For the setting of the heating unit 3, it is preferred to adopt an electric heating solution. In this embodiment, the heating unit 3 includes a plurality of electric heating elements 30 arranged on the inner side of the fabric 2, and a heating controller 31; the heating controller 31 is used to control the working state of each electric heating element 30. Among them, the heating wire 30 can adopt a flexible electric heating wire or a flexible heating sheet. The electric heating method using the electric heating element 30 is convenient for technical implementation, and the heating state of each electric heating element 30 can be flexibly controlled by the heating controller 31, thereby realizing the temperature control of the fabric 2.

[0043] The arrangement of the heating wires 30 can be flexibly arranged according to the heating temperature control requirements of the fabric 2; when the thermochromic coating on the fabric 2 adopts a single color change mode of a single color, each electric heating element 30 can be evenly arranged over the entire surface of the fabric 2.

[0044] When the fabric 2 is divided into multiple color-changing areas, the thermochromic coating in some color-changing areas may adopt a single color-changing mode, and the thermochromic coating in some color-changing areas may adopt a combined color-changing mode. Therefore, different color-changing areas have different temperature control requirements. Based on different temperature rise requirements, the fabric 2 is divided into multiple color-changing areas, and the electric heating elements 30 in different color-changing areas are evenly arranged with different densities. In this way, the electric heating elements 30 are arranged in corresponding densities in each color-changing area, which can better meet the temperature control needs of each color-changing area on the fabric 2.

[0045] To sum up, the thermochromic ceiling of this embodiment can change the color of the fabric 2 by applying a thermochromic coating on the fabric 2 of the car ceiling and controlling the temperature of the fabric 2 by using the heating unit 3 in the car ceiling; when the temperature of the fabric 2 does not reach the set color change temperature, the appearance of the car ceiling presents a traditional decorative effect; when the temperature of the fabric 2 rises to a preset temperature, the car ceiling will present a preset color or pattern, thereby enhancing the decoration and atmosphere creation effect of the car ceiling.

[0046] Embodiment 2

[0047] This embodiment relates to a vehicle, the roof of which adopts the thermochromic roof provided in the first embodiment.

[0048] Furthermore, the heating unit 3 is preferably connected to the vehicle computer system, and the heating unit 3 responds to the control of the vehicle computer system to adjust the temperature of the fabric 2. By controlling the heating unit 3 using the vehicle computer system, the temperature of the fabric 2 can be flexibly adjusted through the vehicle control panel, thereby integrating the control of the thermochromic ceiling into the vehicle control system, which not only further enriches the functional role of the vehicle computer system, but also makes the control method of the thermochromic ceiling more convenient and friendly.

[0049] By using the above-mentioned thermochromic ceiling, the fabric 2 can change color or pattern with temperature and can present complex patterns. The fabric 2 can passively change color when the external temperature changes, or it can be actively controlled by the vehicle system, so that the car ceiling can adapt to the temperature change display needs of multiple scenarios.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
