[0027] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0028] The terms "including" and "having" and any variations thereof in the specification, claims and drawings of the present disclosure are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0029] The present disclosure provides a vehicle interior customization device, see Figure 1 The vehicle interior customization device includes a flexible screen 1, a pressure sensor 2, a digital converter 3 and a control chip 4. The pressure sensor 2 is arranged at the lower part of the flexible screen 1, and is used to obtain the touch pressure of the flexible screen 1. The digital converter 3 is electrically connected with the pressure sensor 2 and the control chip 4, and is used to convert the output signal of the pressure sensor 2 into a digital signal and transmit it to the control chip 4. The control chip 4 is used to adjust the thickness of the brush at the touch point of the flexible screen 1 according to the received digital signal.

[0030] The disclosed embodiment provides a vehicle interior customization device, which can be set on the vehicle dashboard trim, the inner panel trim of the front and rear four doors, and the vehicle ceiling area, and replace the original leather material interior with a flexible screen with a hand-painted function.

[0031] The surface of vehicle interior is varied, including straight lines, curves and even irregular shapes. In order to make the flexible screen fit closely to various complex curved surfaces and keep the screen flat and wrinkle-free, an independent flexible screen module is designed in each area of ​​the vehicle. 3D scanning technology is used to accurately measure the interior surface and obtain accurate data parameters of each area so that the flexible screen can accurately fit the interior surface. In the process of fitting the flexible screen to the interior surface, a 3D scanning device is used to scan the interior surface in all directions. The 3D scanning device can emit dense laser beams or structured light. When these lights hit the interior surface, they will reflect. The reflected light contains information such as the shape and texture of the surface. The device receives the reflected light for calculation and analysis, thereby accurately measuring the three-dimensional shape of the interior surface. For each area of ​​the interior, the 3D scanning device can measure the curvature, angle, height difference and other detailed information of the corresponding area. For example, in the dashboard area, the device can accurately capture its unique arc shape and complex surface changes; in the door interior panel area, it can accurately measure various decorative lines and uneven surface features, which can be used for subsequent flexible screen adaptation.

[0032] The acquired appearance data of each area is input into the design software, and the flexible screen is cut and shaped according to the specific shape and size of the interior surface, so that the flexible screen can fit perfectly on each interior surface; at the same time, it can also ensure the stability and reliability of the flexible screen during the installation process, avoid looseness, wrinkling or non-fitting, and thus improve the user experience.

[0033] In addition, the flexible screen uses a support frame with built-in memory alloy and low-volatile pressure-sensitive adhesive to ensure that it can maintain a good fit under different temperature and humidity conditions.

[0034] Memory alloys can maintain a specific shape at different temperatures. When the ambient temperature changes, the memory alloy will adjust according to the preset shape memory characteristics. At higher temperatures, the memory alloy support frame can maintain a stable structure, provide uniform support for the flexible screen, and prevent the flexible screen from deforming or detaching from the interior surface due to thermal expansion; at lower temperatures, the memory alloy will not become too fragile and can still maintain its supporting role, ensuring that the flexible screen fits tightly with the interior. At the same time, the elasticity of the memory alloy can also adapt to a certain degree of external force impact, providing additional protection for the flexible screen. A support frame with built-in memory alloy is used to support the flexible screen to improve the reliability of the flexible screen in long-term use.

[0035] Low-volatility pressure-sensitive adhesive is used to bond during the lamination process. It has low volatility and can maintain stable viscosity under different temperature and humidity conditions, thereby ensuring a close fit between the flexible screen and the interior surface. In addition, the low volatility characteristic can also reduce pollution to the interior environment of the car.

[0036] Through the synergistic effect of the built-in memory alloy support frame and low-volatile pressure-sensitive adhesive, the flexible screen can maintain a good fit under a variety of temperature and humidity conditions, bringing users a long-lasting and stable user experience.

[0037] The flexible screen itself uses an enhanced polymer substrate and is combined with a nano coating to improve the scratch resistance and chemical corrosion resistance of each flexible screen. The nano coating preferably uses an inorganic nano coating material, which is composed of special nanoparticles with high hardness and good chemical stability. When the nano coating is covered on the enhanced polymer substrate of the flexible screen, the nanoparticles are closely arranged together to form a solid protective film. This protective film can not only effectively improve the scratch resistance of each flexible screen, making the flexible screen less likely to be scratched in daily use, but also enhance its chemical corrosion resistance and prevent various chemicals from damaging the screen. At the same time, the nano coating also has a certain anti-glare function. By scattering and absorbing light, it reduces the strong light reflected by the screen, bringing users a more comfortable visual experience. In the process of matching the substrate and the nano coating, the enhanced polymer substrate can be well combined with the nanoparticles of the nano coating, ensuring that the nano coating is firmly attached to the substrate, thereby exerting the best protection effect. In addition, during daily use, a transparent anti-scratch protective film can also be pasted to reduce daily wear.

[0038] The flexible screen backplane material uses materials with high thermal conductivity such as graphene composite materials, and a microchannel cooling system is integrated behind the flexible screen to improve heat dissipation efficiency. For flexible screens set on the trim panels on the inner guard plates of the front and rear doors and the roof area of ​​the vehicle, it is not easy to integrate a microchannel cooling system. High thermal conductivity materials can be used for heat dissipation. For flexible screens set on the trim panels on the dashboard, etc., which are close to the vehicle's air-conditioning system and are prone to overheating due to factors such as direct sunlight, a microchannel cooling system can be designed. The circulation pipeline of the microchannel cooling system can use the vehicle's existing air-conditioning system, coolant system or battery pack cooling system for heat exchange. The cooling medium inside the microchannel cooling system circulates in the microchannel structure, the manifolds at both ends of the microchannel structure, and the circulation pipeline, thereby exporting the heat at the flexible screen, reducing the local hot spot temperature, ensuring that the flexible screen is at a normal operating temperature, and preventing problems such as malfunctions or performance degradation due to overheating. The flexible screen can also dynamically control the screen brightness and refresh rate under the adjustment of the system based on the data fed back by the temperature sensor, reasonably allocate energy consumption, and reduce heat generation.

[0039] Electromagnetic shielding layers are embedded around and inside each flexible screen to isolate external interference while ensuring that internal signals will not affect the outside world. The operating frequency band of the communication module is adjusted through software to avoid known high-frequency interference sources in the car, and frequency hopping technology is used to further reduce potential interference problems.

[0040] By setting a pressure sensor at the bottom of the flexible screen, it is possible to sense the touch pressure of the user when drawing on the flexible screen, and adjust the thickness of the brush according to the touch pressure, thereby simulating a more realistic actual drawing state and improving the user's drawing efficiency and drawing experience.

[0041] On the one hand, the control chip is electrically connected to the flexible screen to realize the control function of the conventional touch display, and on the other hand, it is connected to the pressure sensor through a digital converter. Compared with the traditional flexible screen structure, the pressure sensor and the digital converter are additionally added in this embodiment. The pressure sensor can overlap with the entire surface of the flexible screen to fully obtain the pressure changes at various locations of the flexible screen. The pressure sensor adopts a resistive pressure sensor. When the user touches the flexible screen and draws a pattern on the screen, a certain amount of pressure will be applied to the flexible screen at the touch position. The pressure is transmitted to the pressure sensor through the flexible screen, so that the resistance value of the pressure sensor changes. The pressure sensor can judge the touch position according to the area where the resistance value changes, and judge the pressure based on the size of the resistance value change. The output signal of the pressure sensor is converted into a digital signal by a digital converter and transmitted to the control chip. The control chip pre-stores the corresponding relationship between the pressure size and the thickness of the brush. After the control chip converts the received digital signal into the pressure size, it compares it with the pre-stored corresponding relationship, thereby determining the brush thickness corresponding to the current touch position, and feedbacks it to the flexible screen for display.

[0042] In a possible implementation, the pressure is positively correlated with the thickness of the brush, that is, the greater the pressure, the thicker the brush, and the smaller the pressure, the thinner the brush. This relationship is consistent with the cognitive habits of users in general, and can simulate the state of users drawing with real brushes, thereby improving user experience.

[0043] In one possible implementation, the device also includes a microphone array 5, which is used to receive sound signals for voice control to adjust the brush color and the like. The microphone array can be additionally provided on one side of the flexible screen. In addition, if the vehicle itself has a microphone, the function can also be integrated with the vehicle system itself. The microphone array is connected to a digital converter, which converts the voice signal into a digital signal and transmits it to the control chip. The control chip performs control actions according to the received voice commands. A fixed wake-up word can be set, for example: "Hello, change the brush color to xx color". When the control chip receives a signal corresponding to the wake-up word, the voice control function is executed and the brush is switched to the color required by the user.

[0044] In one possible implementation, the device also includes a start button, and the drawing function is manually started through a specific start button to avoid accidental touches during daily use. In addition, the start function can also be integrated into the vehicle computer, and wake-up, lock and other instructions can be executed through the vehicle's central control screen. When there is a start button, the start button is electrically connected to the flexible screen, pressure sensor, digital converter, control chip, and microphone array. In the default state, the display color of the flexible screen is consistent with the main body of the interior. When the button is pressed, the device starts and can draw patterns by itself to achieve customization of the interior.

[0045] The disclosed embodiment also provides a vehicle, wherein the vehicle has a plurality of vehicle interior customization devices as described in any one of the above items. Preferably, the above devices can be provided on the dashboard trim inside the vehicle, the trim on the inner panels of the front and rear four doors, and the vehicle ceiling area to meet the user's customization needs for the interior color and / or pattern of these areas.

[0046] In a possible implementation, the vehicle further includes a central control screen and a processor, the central control screen is electrically connected to the processor for realizing human-computer interaction, and the processor is electrically connected to each vehicle interior customization device for realizing linkage control between each vehicle interior customization device. In this implementation, each vehicle interior customization device can realize independent and linkage control based on the central control screen, and based on the linkage control, the pattern drawn by the user can be further realized to be dynamically displayed between the flexible screens of each device, so as to further improve the intelligence of the vehicle.

[0047] Based on the vehicle provided above, the embodiment of the present disclosure further provides a method for customizing vehicle interior. The method includes:

[0048] In response to a user's touch operation on the flexible screen, a brush trace is generated at the touch position according to a preset brush type and brush color;

[0049] During the brush stroke generation process, the pressure at the touch point is obtained in real time;

[0050] The thickness of the brush marks at the touch point is determined according to the pressure at the touch point.

[0051] When the provided vehicle interior customization device is not used, the display of each flexible screen is in the default state, and the pattern and color are consistent with the main color of the vehicle interior. When the user presses the start button or clicks the start command in the vehicle's central control screen, the device runs, the drawable area of ​​the flexible screen is awakened, and the user can now draw.

[0052] See also Figure 2After the device is started, you first need to select the brush type and brush color. The selectable brush types will be displayed on the screen after the flexible screen is lit, and the user clicks to select. After the brush selection is completed, the next step is to select the brush color. If the user does not select a color, the default is black. In addition, during the drawing process, the brush color can also be modified in real time through voice control. The user can issue a voice command "Hello, change the brush color to xx color" to wake up the voice modification brush color function.

[0053] See also Figure 3 , after completing the brush settings, draw and clear the pattern. When the user is drawing a pattern, the pressure sensor is used to obtain the pressure of the user's fingertips touching the flexible screen in real time, and the thickness of the brush marks at the touched point is determined according to the pressure at the touched point. The pressure is proportional to the thickness of the brush. The greater the pressure, the thicker the drawn line. After each line drawing, determine whether a clear operation needs to be performed. If you need to clear the drawn lines, press and hold the corresponding line for 2 seconds. After long pressing, a pop-up window will be displayed to confirm whether to clear. After selecting yes, the system will determine that a clear action needs to be performed, and the lines in the corresponding area will be cleared according to the received pressure signal.

[0054] After the pattern is drawn, the pattern can be further linked between the customized devices of the vehicle interior. This function needs to be implemented in the vehicle system. The system responds to the user's interactive instructions, obtains the user's selected pattern, input trajectory and movement mode; then controls the selected pattern to move along the input trajectory between the customized devices of the vehicle interior according to the preset movement mode. For details, see Figure 4 , this function is the pattern interaction function. The car system is preset with an APP that realizes the pattern interaction function. Users can choose to open the APP in the vehicle's central control screen, select the pattern to be animated, and the animation to be added, such as bouncing up and down, rotating on the spot, etc. If the user has the need to further enhance the interactivity, after completing the animation selection, the movement trajectory of the pattern can be further customized. For example, let the pattern move from the trim on the inner guard plate of the front door to the ceiling. The specific movement trajectory can be drawn by the user. After selecting the trajectory movement operation in the APP, you can directly draw the trajectory. After the drawing is completed, you can further set the movement time (speed), number of repetitions, etc. After completing all settings, confirm the trajectory and execute it, so that the selected pattern moves along the input trajectory according to the preset movement method (animation, movement time, number of repetitions, etc.).
