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

[0028] The terms "comprise" and "have" and any variations thereof in the specification and claims of the present disclosure and the drawings are intended to cover non-exclusive inclusion. 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 can optionally also include steps or units not listed, or can optionally also include other steps or units inherent to these processes, methods, products or devices.

[0029] The embodiments of the present disclosure provide a vehicle interior self-defining device, referring to Figure 1 The vehicle interior self-defining 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 received by 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 the digital signal to the control chip 4. The control chip 4 is used to adjust the brush thickness at the touch position of the flexible screen 1 according to the received digital signal.

[0030] The embodiments of the present disclosure provide a vehicle interior self-defining device. The device can be arranged on the decorative plate of the inner guard plate of the dashboard, the front and rear four vehicle doors and the ceiling area of the vehicle, and the original skin material interior is replaced by the flexible screen with hand-drawing function.

[0031] The interior surface of a vehicle is complex, including straight lines, curves, and even irregular shapes. In order to make the flexible screen closely fit various complex curved surfaces and maintain the screen flat and wrinkle-free, a separate flexible screen module is designed for each area of the vehicle. The 3D scanning technology is used to accurately measure the interior surface and obtain accurate data parameters for each area, so that the flexible screen can accurately adapt to the interior surface. In the process of adapting 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, which will reflect when they hit the interior surface. The reflected light contains information about the shape and texture of the surface, and the device receives and analyzes the reflected light to accurately measure 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 instrument panel area, the device can accurately capture the unique arc shape and complex curve 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 appearance data of each area obtained 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 perfectly fit each interior surface; at the same time, it can also ensure the stability and reliability of the flexible screen during installation, avoiding loose, wrinkled or not fitting conditions, and thus improving user experience.

[0033] In addition, the flexible screen uses a support frame with built-in memory alloy and low-volatility pressure-sensitive adhesive to ensure good fitting state under different temperature and humidity conditions.

[0034] Memory alloy can maintain a specific shape at different temperatures, and 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 to provide uniform support for the flexible screen, preventing 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 will still maintain its support function, ensuring that the flexible screen is closely fitted to the interior. At the same time, the elasticity of the memory alloy can also adapt to a certain degree of external impact, providing additional protection for the flexible screen. The use of a support frame with built-in memory alloy to support the flexible screen can improve the reliability of the flexible screen during long-term use.

[0035] Low-volatility pressure-sensitive adhesive is used to play a bonding role during the fitting process. It has low volatility and can maintain stable adhesion under different temperature and humidity conditions, ensuring the close fit between the flexible screen and the interior surface. In addition, the low volatility feature can also reduce pollution to the vehicle interior environment.

[0036] Through the synergistic effect of the built-in memory alloy support frame and the low-volatility pressure-sensitive adhesive, the flexible screen can maintain good adhesion under various temperature and humidity conditions, providing users with a persistent and stable user experience.

[0037] The flexible screen itself uses a reinforced polymer substrate and is coated with a nano-coating to improve the scratch resistance and chemical corrosion resistance of each flexible screen. The nano-coating preferably uses inorganic nano-coating materials composed of special nanoparticles with high hardness and good chemical stability. When the nano-coating is applied to the reinforced polymer substrate of the flexible screen, the nanoparticles will closely arrange together to form a layer of strong protective film. This protective film not only effectively improves the scratch resistance of each flexible screen, making it less likely to be scratched during daily use, but also enhances its chemical corrosion resistance, preventing damage to the screen by various chemicals. At the same time, the nano-coating also has a certain anti-glare function, scattering and absorbing light to reduce the reflection of strong light on the screen, providing users with a more comfortable visual experience. During the cooperation of the substrate and the nano-coating, the reinforced 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 protective effect. In addition, a transparent scratch-resistant protective film can be attached during daily use to reduce daily wear and tear.

[0038] The flexible screen backplate material is made of high thermal conductivity materials such as graphene composite materials, and a micro-channel cooling system is integrated behind the flexible screen to improve heat dissipation efficiency. For the flexible screens installed on the inner panels of the front and rear four doors and the area of the vehicle roof, the micro-channel cooling system cannot be integrated, and high thermal conductivity materials can be used for heat dissipation. For the flexible screens installed on the instrument panel and other places, which are close to the vehicle's air conditioning system and are prone to overheating due to direct sunlight and other factors, a micro-channel cooling system can be designed. The circulating pipeline of the micro-channel cooling system can use the existing air conditioning system, cooling liquid system, or battery pack cooling system of the vehicle for heat exchange. The cooling medium inside the micro-channel cooling system circulates in the micro-channel structure, the manifold at both ends of the micro-channel structure, and the circulating pipeline, thereby conducting heat away from the flexible screen, reducing local hotspot temperature, and ensuring that the flexible screen is at a normal working temperature, preventing overheating and performance degradation.

[0039] Each flexible screen is embedded with an electromagnetic shielding layer around the periphery and inside, isolating external interference while ensuring that internal signals do not affect the outside. By adjusting the working frequency band of the communication module through software, known high-frequency interference sources inside the vehicle are avoided, and frequency hopping technology is used to further reduce potential interference problems.

[0040] By setting the pressure sensor under the flexible screen, the touch pressure of the user when drawing on the flexible screen can be sensed, and the brush thickness is adjusted according to the touch pressure, so that a more realistic actual drawing state is simulated, and the drawing efficiency and drawing experience of the user are improved.

[0041] The control chip is electrically connected with the flexible screen, thereby realizing the control function of the conventional touch display, and is connected with the pressure sensor through the digital converter. Compared with the conventional flexible screen structure, the pressure sensor and the digital converter are additionally added in the embodiment, the pressure sensor can overlap the entire surface of the flexible screen, so as to fully obtain the pressure change of each part of the flexible screen. The pressure sensor adopts a resistance type pressure sensor, when the user touches the flexible screen and draws a pattern on the screen, a certain size of pressure is 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 of the resistance value change, and the pressure size is judged based on the size of the resistance value change. The output signal of the pressure sensor is converted into a digital signal by the digital converter and transmitted to the control chip. The control chip pre-stores the corresponding relationship between the pressure size and the brush thickness, the control chip converts the received digital signal into the pressure size, compares it with the pre-stored corresponding relationship, thereby determines the brush thickness corresponding to the current touch position, and feeds back to the flexible screen to be displayed.

[0042] In a possible implementation, the pressure size and the brush thickness are positively correlated, that is, the larger the pressure, the thicker the brush, and the smaller the pressure, the thinner the brush. The relationship conforms to the cognitive habit of the user in general, can simulate the state of the user drawing with a real brush, and improves the user experience.

[0043] In a possible implementation, the device further comprises a microphone array 5, which is used to receive a sound signal to perform voice control and realize adjustment of the brush color and the like. The microphone array can be additionally arranged on one side of the flexible screen, in addition, if the vehicle itself has a microphone, the function can also be integrated with the car system itself. The microphone array is connected with the digital converter, converts the voice signal into a digital signal and transmits it to the control chip. The control chip executes the control action according to the received voice instruction. A fixed wake-up word can be set, for example: "Hello, change the brush color to xx color", when the control chip receives the 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 a possible implementation, the device further comprises a start button, and the drawing function is manually started through the specific start button to avoid accidental touch during daily use. In addition, the start function can also be integrated into the car machine, and the wake-up, locking and other instructions are executed through the vehicle central control screen. When the start button is provided, the start button is electrically connected with the flexible screen, the pressure sensor, the digital converter, the control chip and the microphone array. In the default state, the display color of the flexible screen is consistent with the main body of the interior trim. When the button is pressed, the device starts, and the user can draw patterns by himself / herself to realize the customization of the interior trim.

[0045] The embodiments of the present disclosure further provide a vehicle, and the vehicle comprises a plurality of the vehicle interior customization devices described in any one of the above. Preferably, the devices are arranged on the dashboard, the inner panels of the front and rear four doors, and the ceiling area of the vehicle to meet the customization needs of the user for the color and / or pattern of the interior trim in these areas.

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

[0047] Based on the vehicle provided in the above, the embodiments of the present disclosure further provide a vehicle interior customization method. The method comprises:

[0048] In response to the touch operation of the user on the flexible screen, the pen trace is generated at the touch position according to the pre-set brush type and brush color;

[0049] In the process of generating the pen trace, the pressure at the touch position is acquired in real time;

[0050] The thickness of the pen trace at the touch position is determined according to the pressure at the touch position.

[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 trim. When the user presses the start button or clicks the start instruction in the vehicle central control screen, the device runs, and the drawable area of the flexible screen is woken up. At this time, the user can perform the drawing operation.

[0052] Referring to Figure 2After the device is started, the user first needs to select a brush type and a brush color. The selectable brush types are displayed on the screen after the flexible screen is turned on, and the user selects the brush type by clicking. After the brush type is selected, the user selects a brush color. If the user does not select a brush color, the default brush color is black. In addition, during the drawing process, the user can modify the brush color in real time by voice control. The user issues a voice command "Hello, change the brush color to xx color" to wake up the function of modifying the brush color by voice.

[0053] Referring to Figure 3 After the brush setting is completed, the user draws a pattern and clears the pattern. During the drawing process, the pressure sensor acquires the pressure of the user's fingertip on the flexible screen in real time, and the pressure of the fingertip on the flexible screen determines the thickness of the brush stroke. The pressure and the thickness of the brush stroke are directly proportional. The greater the pressure, the thicker the line drawn. After each line is drawn, it is determined whether the line needs to be cleared. If the line needs to be cleared, the user long-presses the line for 2 seconds. After the long-pressing, a pop-up window is displayed to confirm whether the line needs to be cleared. If the user selects Yes, the system determines that the line needs to be cleared, and the line is cleared according to the received pressure signal.

[0054] After the pattern is drawn, the pattern can be further implemented to move between the custom devices in the vehicle interior. This function needs to be implemented in the vehicle system. The system responds to the user's interactive command, acquires the user-selected pattern, input trajectory, and movement mode, and then controls the selected pattern to move between the custom devices in the vehicle interior according to the preset movement mode along the input trajectory. Specifically, referring to Figure 4 This function is a pattern interaction function. The vehicle system has an APP that implements the pattern interaction function. The user can open the APP in the vehicle's central control screen, select a pattern that needs to be animated, and select an animation, such as jumping up and down or rotating in place. If the user needs to further enhance the interactivity, the user can further customize the movement trajectory of the pattern after the animation is selected. For example, the pattern moves from the front door inner panel to the ceiling. The user can draw the trajectory directly after selecting the trajectory movement operation in the APP. After the trajectory is drawn, the user can further set the movement time (speed), the number of repetitions, and the like. After all the settings are confirmed, the trajectory is executed, and the selected pattern moves along the input trajectory according to the preset movement mode (animation, movement time, number of repetitions, and the like).
