[0002] With the development of the automobile industry, users have higher and higher requirements for the quality of vehicles. The quality of a vehicle is not only reflected in the driving comfort and handling performance of the vehicle, but also in aspects such as the vehicle interior. Vehicle interior parts mainly include door panels, door inserts, door pillars, sun visors, roof canopies, rear window sills, trunk side panels, door storage boxes, instrument panels, atmosphere lights, floor mats, carpets, seat belts, etc. Most interior decoration parts have a relatively simple color design. Luminous interior decoration parts (atmosphere lights) can adjust the light color by changing the light source, but this change in light color requires the user to adjust it by changing the control program (such as manually switching colors), and the adjustment effect is also relatively simple. In general, the color design of existing vehicle interior parts is single, which is difficult to meet the user's needs for fun and playability. Summary of the invention

[0034] In the claims, description and drawings of the present invention, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0035] Please also read Figures 1 to 5 The color-changing interior structure provided by the present invention is now described. The color-changing interior structure comprises a temperature-sensitive color-changing housing 1, the temperature-sensitive color-changing housing 1 has a ventilation cavity 110 and a vent 120 connected to the ventilation cavity 110, and the vent 120 is connected to the air supply module.

[0036] In this embodiment, the air supply module connected to the vent 120 can be a main air-conditioning module for adjusting the temperature of the passenger compartment, or it can be a secondary air-conditioning module independently provided from the main air-conditioning module. The secondary air-conditioning module is mainly used to supply air into the ventilation cavity 110 and basically does not participate in regulating the temperature of the passenger compartment.

[0037] In the present embodiment, the temperature-sensitive color-changing housing 1 is made of a temperature-sensitive color-changing material. The temperature-sensitive color-changing material is made by adding a reversible temperature-sensitive color-changing auxiliary agent (color powder, masterbatch, paint form) to a base material, and is made by injection molding, printing and other processes. The reversible temperature-sensitive color-changing auxiliary agent is made of a reversible thermochromic pigment, and the reversible thermochromic pigment is prepared from an electron transfer type organic compound system. The electron transfer type organic compound is a type of organic color-changing system with a special chemical structure. At a specific temperature, the molecular structure of the organic matter changes due to electron transfer, thereby achieving color change. This color-changing substance is not only bright in color, but also can achieve color changes from "colored to colorless" and "colorless to colored" states. The temperature-sensitive color-changing housing 1 of the present embodiment is made by mixing a temperature-sensitive color-changing auxiliary agent into a base material for injection molding.

[0038] The thermochromic points of thermochromic materials are mainly concentrated in the range of 15 to 70°C (for example, 8°C, 22°C, 31°C, 33°C, 45°C, 65°C, etc.). Generally speaking, the number of thermochromic points of thermochromic materials corresponds to the type of thermochromic additives added. If only a single thermochromic additive is added to the base material, the thermochromic material has only one thermochromic point, and the thermochromic material can switch between two colors; if two thermochromic additives are added to the base material, the thermochromic material has two thermochromic points, and the thermochromic material can switch between three colors; even more complex combinations can be used to make a thermochromic material have no less than three thermochromic points, and the principle will not be repeated here. The main point is that the thermochromic additive and the base material are mixed with each other, but no chemical reaction occurs. For example, the temperature-sensitive color-changing additive can be a temperature-sensitive microcapsule powder with a particle size of 3 to 10 um, which is suitable for base materials such as inks, coatings and plastics (such as PE, PP, PS, PVC, PVA, PET, Nylon), and has a temperature resistance of up to 230°C; the temperature-sensitive color-changing additive can be a temperature-sensitive water emulsion, which is an aqueous dispersant containing microcapsules with an average particle size of 3 to 10 um, which is suitable for base materials such as inks and coatings; the temperature-sensitive color-changing additive can be a temperature-sensitive masterbatch, which contains 12-18% microcapsule material. Microcapsule materials of different colors have different color intensities and are suitable for base materials such as plastics (such as PE, PP, PS, PVC, PVA, PET, Nylon).

[0039] Take the implementation method in which two kinds of thermochromic additives are mixed in the base material as an example, the thermochromic point of one thermochromic additive is 18°C, below 18°C ​​it is purple, above 18°C ​​it is colorless, and the thermochromic point of the other thermochromic additive is 31°C, below 31°C it is blue, above 31°C it is red. Under normal temperature (the temperature in the car is 18-31°C), the thermochromic material is blue as a whole; if cold air below 18°C ​​is introduced into the ventilation cavity under normal temperature, the temperature of the thermochromic material itself will gradually decrease to no higher than 18°C, so the color of the thermochromic material switches from blue to purple; if hot air above 31°C is introduced into the ventilation cavity under normal temperature, the temperature of the thermochromic material itself will gradually increase to no less than 31°C, so the color of the thermochromic material switches from blue to red. It should be understood that the above-mentioned temperature and corresponding color changes are only exemplary illustrations, and "normal temperature" is related to the actual temperature of the passenger compartment, which is in turn affected by the environment of the user's area. The temperature-sensitive color-changing point of the thermochromic material is related to the type of material. Thermochromic materials with different temperature-sensitive color-changing points can be selected according to the temperature in different regions. This is not a sole limitation.

[0040] In this embodiment, in order to achieve the effect of effectively adjusting the temperature-sensitive color-changing shell 1, a side wall of the ventilation cavity 110 directly corresponds to the decorative surface of the temperature-sensitive color-changing shell 1, and the coverage area of ​​the ventilation cavity 110 roughly corresponds to the coverage area of ​​the decorative surface.

[0041] The temperature-sensitive color-changing housing 1 in this embodiment can be arranged in the following ways:

[0042] 1) The temperature-sensitive color-changing housing 1 is made of the same temperature-sensitive color-changing material as a whole, and the temperature-sensitive color-changing housing 1 can only present one color at a corresponding temperature.

[0043] 2) The temperature-sensitive color-changing housing 1 is composed of a variety of temperature-sensitive color-changing materials, so that the decorative surface of the temperature-sensitive color-changing housing 1 has multiple color-changing areas. Different color-changing areas present different colors at the same temperature, so the decorative surface can present multiple colors at the corresponding temperature.

[0044] 3) The thermochromic housing 1 uses a thermochromic material on the side facing the passenger compartment, and uses a conventional material (such as conventional plastic that cannot change color) in the covered area, and the two materials can be integrally formed by secondary injection molding. In this case, the decorative surface formed by the thermochromic material can only show one color at the corresponding temperature.

[0045] 4) The temperature-sensitive color-changing shell 1 uses a variety of temperature-sensitive color-changing materials to form a decorative surface on the side facing the passenger compartment, so that the decorative surface has multiple color-changing areas. Different color-changing areas show different colors at the same temperature. Therefore, the decorative surface can show a variety of colors at the corresponding temperature, while conventional materials (such as conventional plastics that cannot change color) are used in the covered area, and several materials can be integrally formed through secondary injection molding.

[0046] In general, the specific setting of the color-changing area in the temperature-sensitive color-changing housing 1 can satisfy the adjustability of the decorative color, and there is no sole limitation.

[0047] In this embodiment, the color-changing interior structure is exemplarily shown as a decorative component arranged on the central control instrument panel 4, and the color-changing interior structure as a whole is a strip-shaped structure extending along the width direction of the vehicle body. However, it should be understood that the color-changing interior structure of this embodiment is applicable to any area in the vehicle with similar color adjustment requirements, and is not limited here.

[0048] Compared with the prior art, the color-changing interior structure provided in the present embodiment has a color-changing temperature-sensitive color-changing outer shell 1 that can present a specified color under normal temperature. If the air supply module sends cold air below normal temperature or hot air above normal temperature into the ventilation cavity 110 through the vent 120, then according to the type of temperature-sensitive color-changing material used in the temperature-sensitive color-changing outer shell 1, after the temperature of the temperature-sensitive color-changing outer shell 1 drops or rises to the temperature-sensitive color-changing point, the color of the temperature-sensitive color-changing outer shell 1 changes, thereby achieving the adjustment of the decorative color. Stopping the air supply to the ventilation cavity 110 can restore the temperature-sensitive color-changing outer shell 1 to the color before the air supply. The present embodiment utilizes temperature-sensitive color-changing materials in conjunction with the vehicle's air supply module. The temperature of the temperature-sensitive color-changing outer shell 1 is adjusted by air supply, and the color is adjusted by changing the temperature of the temperature-sensitive color-changing outer shell 1. The adjustment method is novel, and the fun and playability of the interior color adjustment are effectively improved. At the same time, the color adjustment principle of the present embodiment does not rely on electronic control components. The overall structure of the color-changing interior structure is simple, the number of parts is small, the manufacturing cost is low, and the problem of high failure rate of electronic control adjustment is effectively avoided, which is more convenient for maintenance.

[0049] In some embodiments, the vent 120 is disposed on a side wall of the ventilation cavity 110 that faces away from the passenger compartment. Figures 3 to 5 As shown, the connection area with the air supply module is prevented from being exposed to the outside and affecting the aesthetics.

[0050] In some embodiments, the side wall of the ventilation cavity 110 is also formed with a drainage port (not shown in the figure), which is mainly used to allow the airflow flowing into the ventilation cavity 110 to smoothly flow out of the ventilation cavity 110 without affecting the air intake of the vent 120, so as to maintain the stability of the air pressure in the ventilation cavity 110 and avoid the problem of cracking and damage of the temperature-sensitive color-changing shell 1 caused by excessive air pressure in the ventilation cavity 110. In specific implementation, the drainage port is located on the side wall of the ventilation cavity 110 away from the passenger compartment, or other blocked areas on the temperature-sensitive color-changing shell 1, to avoid opening on the decorative surface to affect the aesthetics.

[0051] In some embodiments, the ventilation cavity 110 is further provided with a lighting module 2, such as Figure 4 As shown, the temperature-sensitive color-changing housing 1 is a light-transmitting housing. Among them, the light-emitting surface of the lighting module 2 faces the decorative surface of the temperature-sensitive color-changing housing 1, and the color-changing interior structure forms a color-changing atmosphere light, which further enhances the decorative function of the color-changing interior structure; in addition, the "light-transmitting housing" in this embodiment is generally a translucent housing, which can meet the demand for light emission on the one hand, and on the other hand, can shield the internal lighting module 2 to ensure the aesthetics of the interior. During specific manufacturing, the temperature-sensitive color-changing housing 1 is formed by injection molding of a temperature-sensitive color-changing additive mixed with a translucent base material; during specific assembly, the power of the lighting module 2 is provided by the vehicle battery.

[0052] It should be noted that in this embodiment, in the non-ventilated state, the temperature of the temperature-sensitive color-changing shell 1 entity is not only affected by the temperature in the passenger compartment, but also by the heat dissipated by the lighting module 2 when it is working; if air is supplied to the ventilation inner cavity 110, the temperature of the temperature-sensitive color-changing shell 1 entity is not only affected by the temperature in the passenger compartment and the heat dissipated by the lighting module 2 when it is working, but also by the air supply temperature. In order to avoid excessive temperature affecting the normal operation of the lighting module 2, when the lighting module 2 is working, an airflow lower than the rated operating temperature of the lighting module 2 is generally supplied to the lighting module 2.

[0053] In this embodiment, the implementation of the lighting module 2 includes but is not limited to LED lamps, incandescent lamps, xenon lamps, etc., which are not limited here. The figure exemplarily shows an embodiment in which the lighting module 2 is an LED light bar, and the assembly method between the light bar and the temperature-sensitive color-changing housing 1 can be plug-in, clip-on, etc., which will not be repeated here.

[0054] In some embodiments, see Figures 2 to 4The ventilation inner cavity 110 includes a first cavity 111 and a second cavity 112 which are interconnected. A control valve 3 is arranged between the first cavity 111 and the second cavity 112. The control valve 3 has a first state in which the first cavity 111 and the second cavity 112 are interconnected, and also has a second state in which the first cavity 111 and the second cavity 112 are separated from each other. The side wall of the second cavity 112 forms a vent 120. The second cavity 112 buffers the airflow flowing in through the vent 120, and prevents the airflow from directly rushing into the first cavity 111, causing an imbalance in the air pressure in the first cavity 111, affecting the stability and smoothness of the gas flow, and is conducive to making the overall temperature change of the temperature-sensitive color-changing housing 1 uniform, and the color change is also more uniform; at the same time, the control valve 3 is built into the temperature-sensitive color-changing housing 1, which promotes the improvement of the overall structural compactness of the color-changing interior structure, prevents the control valve 3 from excessively affecting the layout of the surrounding components of the color-changing interior structure, and also protects the control valve 3 itself.

[0055] In specific implementation, the side wall of the second cavity 112 facing the vent 120 is arc-shaped, and the side wall is roughly flush with the corresponding side wall of the first cavity 111. On the one hand, it can meet the requirements of the appearance design of the temperature-sensitive color-changing housing 1. On the other hand, the arc-shaped side wall also plays a buffering and guiding role for the airflow, further enhancing the stability of the airflow.

[0056] In this embodiment, the control valve 3 is realized in ways including but not limited to an electrically controlled valve (such as a solenoid valve), a one-way mechanical valve, a manually controlled mechanical valve, etc. Taking the one-way mechanical valve as an example, the one-way mechanical valve comprises a seat body connected to the temperature-sensitive color-changing housing, an elastic member connected to the seat body at one end, and a valve plate connected to the other end of the elastic member. The valve plate is closed in a free state. When the air pressure in the second chamber 112 is higher than a preset value, the valve plate is lifted up and can supply air to the first chamber 111. When the air supply module stops supplying air and the air pressure in the second chamber 112 is lower than a preset value, the valve plate automatically returns to a closed state.

[0057] Based on the above-mentioned implementation method of built-in control valve 3, refer to Figures 2 to 4 In some specific embodiments of the manual mechanical valve, the control valve 3 includes a valve plate 310 movably connected to the temperature-sensitive color-changing housing 1, and also includes a control unit 320 connected to the valve plate 310. The side wall of the temperature-sensitive color-changing housing 1 is formed with a first avoidance notch 130, and the control unit 320 is movably arranged in the first avoidance notch 130. The movement of the valve plate 310 is controlled by the handheld control unit 320, thereby realizing the opening and closing of the valve plate 310. The operation is simple, and the overall structure of the control valve 3 is simple and compact, which is suitable for decorative structures with a small volume.

[0058] In the movable arrangement of the valve plate 310 not shown in the first type of figure, the valve plate 310 is inserted into the temperature-sensitive color-changing housing 1 by sliding along a preset direction, and the sliding direction is perpendicular to the distribution path of the first cavity 111 and the second cavity 112. If the valve plate 310 needs to be opened, the extended end of the control part 320 is pulled to slide the valve plate 310 in the temperature-sensitive color-changing housing 1 to achieve opening. Figure 1 For example, if you want to open the valve plate 310, you need to pull the control part 320 in the direction of the passenger compartment; the reverse operation can be closed. In order to maintain the relative sealing of the temperature-sensitive color-changing housing 1, the first avoidance notch 130 and the control part 320 are transition fit or interference fit. In some more specific embodiments, the valve plate 310 can also slide through the first avoidance notch 130.

[0059] In the second type of movable arrangement of the valve plate 310, the valve plate 310 is rotatably connected to the temperature-sensitive color-changing housing 1, and the rotation axis 311 of the valve plate 310 is parallel to the distribution path of the first cavity 111 and the second cavity 112. Figures 2 to 4 As shown, the control unit 320 is arranged at the edge of the valve disc 310 away from the rotating shaft 311; the side wall of the temperature-sensitive color-changing housing 1 is also formed with a second avoidance gap 140 connected with the first avoidance gap 130, and the second avoidance gap 140 corresponds to the connection area between the first cavity 111 and the second cavity 112. The valve disc 310 can be rotated in or out of the second avoidance gap 140, and the control unit 320 can be rotated in or out of the first avoidance gap 130. This embodiment realizes the opening and closing of the valve disc 310 by rotating in and out, and the structure is simple and compact, and the operation is more convenient.

[0060] In a specific implementation, in order to further improve the compactness of the structure, the first avoidance gap 130 is directly opposite to the second avoidance gap 140, and both are straight gaps, such as Figures 2 to 4 As shown, the control part 320 is a plate-shaped component that is roughly flush with the valve plate 310. In addition, in order to maintain the relative sealing of the temperature-sensitive color-changing housing 1, the first avoidance notch 130 and the control part 320 are in transitional fit or interference fit, and the second avoidance notch 140 and the valve plate 310 are in transitional fit or interference fit; under the premise of interference fit, the two side walls of the second avoidance notch 140 can also apply a clamping force to the valve plate 310, thereby improving the stability of the position of the valve plate 310 after closing.

[0061] Of course, the first avoidance gap 130 can also be a gap structure with a bend (not shown in the figure), the second avoidance gap 140 is connected to the end of the first avoidance gap 130, and the control part 320 is a bending component adapted to the shape of the first avoidance gap 130.

[0062] In the movable setting mode of the valve disc 310 not shown in the third type of figure, the valve disc 310 is rotatably connected to the temperature-sensitive color-changing housing 1, and the rotation axis of the valve disc 310 is perpendicular to the distribution path of the first cavity 111 and the second cavity 112. In this embodiment, the control part 320 is fixedly arranged on one side of the valve disc 310 and extends in a direction parallel to the rotation axis. The first avoidance notch 130 is arranged as an arc notch that coincides with the swing path of the control part 320. The arc notch is arranged coaxially with the rotation axis. By turning the control part 320, the rotation action of the valve disc 310 can be controlled, thereby controlling the on-off of the first cavity 111 and the second cavity 112. During specific operation, when the valve plate 310 rotates to an angle roughly flush with the side wall where the rotating shaft 311 of the ventilation cavity 110 is located, it is fully opened; when the valve plate 310 rotates to an angle roughly perpendicular to the side wall where the rotating shaft 311 of the ventilation cavity 110 is located, it is fully closed; wherein, the valve plate 310 can rotate and tilt toward the first cavity 111, and can also rotate and tilt toward the second cavity 112.

[0063] Based on the above embodiments, see Figure 4 , a lighting module 2 is also provided in the first cavity 111, and the temperature-sensitive color-changing housing 1 is a light-transmitting housing. The light-emitting surface of the lighting module 2 faces the decorative surface of the temperature-sensitive color-changing housing 1, and the color-changing interior structure forms a color-changing atmosphere light, which further enhances the decorative function of the color-changing interior structure; in addition, the "light-transmitting housing" in this embodiment is generally a translucent housing, which can meet the demand for light emission on the one hand, and on the other hand, can shield the internal lighting module 2 to ensure the aesthetics of the interior.

[0064] In some embodiments, a control valve 3 (not shown in the figure) is provided at the vent 120, and the control valve 3 can control the opening and closing of the vent 120, so as to realize the external placement of the control valve 3. In this embodiment, the implementation methods of the control valve 3 include but are not limited to an electrically controlled valve (such as a solenoid valve), a one-way mechanical valve, a manually controlled mechanical valve, etc. Taking a one-way mechanical valve as an example, the one-way mechanical valve has a seat body connected to a temperature-sensitive color-changing housing, an elastic member connected to the seat body at one end, and a valve plate connected to the other end of the elastic member. The valve plate is closed in a free state. When the wind pressure of the air supply module to the vent is higher than a preset value, the valve plate is lifted up and can supply air to the ventilation cavity. When the wind pressure of the air supply module to the vent is lower than a preset value, the valve plate automatically returns to a closed state. Taking a manually controlled mechanical valve as an example, the control valve includes a valve plate movably connected to the temperature-sensitive color-changing housing, and the user manually moves the valve plate to realize the opening and closing of the vent.

[0065] Based on the aforementioned implementation method of "adding two thermochromic additives to the base material, one of which has a thermochromic point of 18°C, purple below 18°C, and colorless above 18°C, and the other thermochromic point of 31°C, blue below 31°C, and red above 31°C", the color-changing interior structure of the present application has the following effects:

[0066] 1) Based on a bright environment, the cabin is well lit and there is no need to use the lighting function:

[0067] 1-1) The air supply temperature of the air supply module is lower than 18° C. (the temperature of the passenger compartment is generally between 18° C. and 25° C.), and the valve plate 310 is in a closed state, and the decorative surface of the temperature-sensitive color-changing housing 1 is blue.

[0068] 1-2) When the air supply temperature of the air supply module is lower than 18°C ​​(the temperature of the passenger compartment is generally between 18°C ​​and 25°C), the valve plate 310 is opened to allow cold air below 18°C ​​to flow into the first cavity 111, and the color of the temperature-sensitive color-changing housing 1 switches from blue to purple.

[0069] 1-3) When the air supply temperature of the air supply module is higher than 31°C (the temperature of the passenger compartment is generally between 18°C ​​and 25°C), the valve plate 310 is opened to allow hot air with a temperature higher than 31°C to flow into the first cavity 111, and the color of the temperature-sensitive color-changing housing 1 switches from blue to red.

[0070] 1-4) When the air supply temperature of the air supply module is lower than 18°C ​​or higher than 31°C (the temperature of the passenger compartment is generally between 18 and 25°C), and the temperature-sensitive color-changing shell 1 is in the initial state of purple or red, close the valve plate 310 or close the air supply module, and the color of the temperature-sensitive color-changing shell 1 switches from purple or red to blue.

[0071] 1) Based on the dark environment, the light in the passenger cabin is insufficient, and the lighting function is turned on:

[0072] 2-1) When the air supply module is in the closed state, the heat emitted by the lighting module 2 raises the temperature of the ventilation cavity to a temperature higher than 31° C., the color of the temperature-sensitive color-changing housing 1 turns red, and the color of the emitted light also turns red.

[0073] 2-2) The air supply temperature of the air supply module is lower than 18°C ​​(the temperature of the passenger compartment is generally between 18 and 25°C), and the valve plate 310 is in a closed state, the color of the temperature-sensitive color-changing housing 1 is still red, and the color of the emitted light is also red.

[0074] 2-3) When the air supply temperature of the air supply module is lower than 18°C ​​(the temperature of the passenger compartment is generally between 18°C ​​and 25°C), the valve plate 310 is opened to allow cold air with a temperature lower than 18°C ​​to flow into the first cavity 111, and the color of the temperature-sensitive color-changing housing 1 switches from red to purple.

[0075] 2-4) The air supply module remains in a closed state, but a normal temperature airflow flows in its air path. The valve plate 310 is opened, and the normal temperature airflow takes away the heat emitted by the lighting module 2. The temperature in the first cavity 111 gradually decreases to normal temperature, and the color of the temperature-sensitive color-changing housing 1 switches from red to blue, and the color of the emitted light is blue.

[0076] 2-5) When the air supply temperature of the air supply module is higher than 31°C (the temperature of the passenger compartment is generally between 18°C ​​and 25°C), the valve plate 310 is opened to allow hot air with a temperature higher than 31°C to flow into the first cavity 111. The temperature-sensitive color-changing housing 1 is still red, and the color of the emitted light is also red.

[0077] 2-6) When the air supply temperature of the air supply module is lower than 18°C ​​or higher than 31°C (the temperature of the passenger compartment is generally between 18 and 25°C), and the temperature-sensitive color-changing shell 1 is in the initial state of purple or blue, close the valve plate 310 or close the air supply module, and the color of the temperature-sensitive color-changing shell 1 switches from purple or blue to red.

[0078] The color-changing interior structure of the present application can apply the temperature-sensitive color-changing material to the vehicle interior to make a temperature-sensitive color-changing interior part. By reorganizing with the conventional air supply module in the vehicle to control the temperature change of the temperature-sensitive color-changing shell 1, the color change of the interior part is controlled, and finally the effect of creating a cabin atmosphere (light) and changing the color of the cabin is achieved, and the control is more interesting and playable; at the same time, the temperature-sensitive color-changing shell 1 is not affected by the electric control components, and a low-cost replacement for the existing atmosphere lights that are electrically controlled to adjust the color is achieved, and the thermal energy of the lighting module 2 and the wind energy of the air supply module are fully utilized, and the energy utilization rate is higher.

[0079] Based on the same inventive concept, an embodiment of the present application further provides a vehicle, comprising the above-mentioned color-variable interior structure.

[0080] Compared with the prior art, the vehicle provided in this embodiment adopts the above-mentioned color-changing interior structure, so the adjustment of the interior color is more interesting and playable. At the same time, the manufacturing cost is low, and the problem of high failure rate of electronic control adjustment is effectively avoided, which is more convenient for maintenance.

[0081] Based on the same inventive concept, the embodiment of the present application also provides an interior color adjustment method, which is implemented based on the above-mentioned color-variable interior structure and includes the following steps:

[0082] Air is supplied to the ventilation cavity 110 through the vent 120 to adjust the temperature of the temperature-sensitive color-changing shell 1 from the initial temperature to the color-changing temperature, and the color-changing temperature is not higher than the low-temperature color-changing threshold of the temperature-sensitive color-changing shell 1, or the color-changing temperature is not lower than the high-temperature color-changing threshold of the temperature-sensitive color-changing shell.

[0083] The low temperature discoloration threshold and the high temperature discoloration threshold refer to the temperature values ​​corresponding to the temperature-sensitive discoloration points of the temperature-sensitive discoloration material used in the temperature-sensitive discoloration shell 1. In addition, in the non-ventilated state, the temperature of the temperature-sensitive discoloration shell 1 is mainly affected by the temperature in the passenger compartment; if air is supplied to the ventilation cavity 110, the temperature of the temperature-sensitive discoloration shell 1 is affected by the temperature of the passenger compartment as well as the air supply temperature.

[0084] Compared with the prior art, the interior color adjustment method provided in this embodiment is simple in color adjustment of the color-variable interior structure, has strong fun and playability, low failure rate in use, and low maintenance cost, which plays a positive role in improving the quality of the entire vehicle.

[0085] In some embodiments, if the ventilation cavity 110 is divided into a first cavity 111 and a second cavity 112, and the control valve 3 is arranged at the connection between the first cavity 111 and the second cavity 112, then supplying air to the ventilation cavity 110 through the ventilation port 120 specifically also includes: opening the control valve 3, and supplying air to the second cavity 112 and the first cavity 111 in turn through the ventilation port 120.

[0086] If the control valve 3 is an electrically controlled valve, the process of opening the control valve 3 can be achieved by the user operating a control button or a touch screen; if the control valve 3 is a one-way mechanical valve, the opening process of the control valve 3 is automatically performed after the air supply mode of the main air-conditioning module or the auxiliary air-conditioning module is turned on, without the need for user participation; if the control valve 3 is a manually controlled mechanical valve, the opening process of the control valve 3 requires the user to manually move the valve plate to achieve it.

[0087] In other embodiments, if a control valve 3 is provided at the vent 120, supplying air to the vent inner cavity 110 through the vent 120 specifically includes: opening the control valve 3, and supplying air to the vent inner cavity 110 through the vent 120. The process of opening the control valve 3 is similar to the process of providing the control valve 3 between the first cavity 111 and the second cavity 112, and will not be described in detail herein.

[0088] In some embodiments, if a lighting module 2 is disposed in the ventilation cavity 110 , the lighting module 2 can be turned on and off by a control button or a touch screen on the hollow instrument panel 4 .

[0089] 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 and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
