Description

Technical Field

[0001] The present invention relates to the field of intelligent textile interaction technology, and in particular to a dynamic interaction system and method for automobile interior decoration based on shape memory alloy. Background Art

[0002] Traditional automotive interior design primarily relies on static decoration, using materials such as leather, plastic, and metal. Decorations often take the form of prints, engravings, or embedded electronic components (such as LED lights). In recent years, with the development of smart cars, users' demand for interactivity and personalization in interiors has increased. Existing technologies have attempted to incorporate dynamic elements into interior design, but the following major solutions and limitations remain.

[0003] Static embroidery uses traditional embroidery techniques in automotive interiors (such as seats, dashboards, and door panels), creating static patterns or semi-3D effects through stitching and thread (such as wire frames). This technology is used in high-end automotive interiors to enhance the aesthetics and cultural connotations of the vehicle interior. However, embroidery patterns are always static, lacking dynamic expression and interactivity, and thus fail to meet the technological demands of modern smart car interiors. Embedded electronics incorporate small electronic components (such as LEDs and micromotors) into automotive interiors to create dynamic effects. For example, LEDs are used to illuminate embroidery patterns, while micromotors drive the mechanical movement of decorative structures, such as welcome lights and dynamic ambient lighting, enhancing the sense of technology within the vehicle interior. However, the bulk and weight of electronic components are incompatible with the lightness and flexibility of embroidery, which can easily cause structural deformation or compromise the aesthetic integrity. Furthermore, their production is complex, costly, and lacks durability. Mechanically driven structures use external mechanical devices (such as levers and gears) to drive the dynamic deformation of interior decorative structures. For example, a robotic arm can pull the edges of an embroidered pattern to create an opening and closing effect. It is usually used for dynamic displays in high-end car interiors, such as welcome devices, but it is bulky and difficult to embed inside the interior; it produces noise during driving, affecting the appearance; and its application scenarios are limited, making it difficult to use in high-frequency interactive scenarios.

[0004] Existing technologies make it difficult to achieve dynamic effects while maintaining the aesthetic integrity of interior decoration; they lack intelligent response mechanisms linked to environmental factors such as temperature and touch, and cannot meet the interactive needs of modern smart cars for interior decoration. In addition, existing materials are prone to fatigue or damage during high-frequency use, making it difficult to ensure long-term stability. Summary of the Invention

[0021] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0022] With the development of smart cars, users are increasingly demanding interactivity and personalization in interiors. Existing technologies have attempted to incorporate dynamic elements into interior design. This invention, specifically targeting automotive interiors, combines shape memory alloys (SMAs) with intangible cultural heritage embroidery, achieving a fusion of dynamic and static elements. This approach transcends the static limitations of traditional embroidery by leveraging the intelligent deformation properties of SMAs to achieve natural and fluid dynamic effects (such as blooming petals and swaying leaves) while preserving the aesthetic integrity of traditional embroidery and enhancing the artistic and technological feel of automotive interiors. Intelligent interactive experience: By triggering SMA deformation through temperature, current, or touch, automotive interior embroidery intelligently connects with the in-vehicle environment (such as lighting and temperature). For example, when a car door is opened, embroidered petals gradually unfold, aligning with the changing interior lighting to create a ceremonial and personalized welcome experience. Lightweight and highly compatible: Leveraging the slenderness and high elasticity of SMAs, they seamlessly integrate with embroidery materials, eliminating the bulk and weight associated with traditional drive materials (such as motors and electronic components), ensuring lightweight and aesthetically pleasing interior design. Durability and Stability: By optimizing the SMA molding process and drive control, dynamic embroidery ensures stability and fatigue resistance under high-frequency use, adapting to the long-term use environment of automotive interiors. Expanding Application Scenarios: Dynamic embroidery can be widely applied to automotive interiors (such as instrument panels, door panels, and seat trim), providing a new interactive aesthetic solution for smart car interior design, meeting user needs for personalization, technological advancements, and cultural connotations.

[0023] The following combination Figure 1 The present invention describes a dynamic interactive system for automobile interior decoration based on shape memory alloy, comprising: Information collection module 1, used to collect instruction information and send the instruction information to control module 2; The control module 2 is electrically connected to the information acquisition module 1 and is used to receive the instruction information and generate a current control instruction according to the instruction information; a discharge module 3, electrically connected to the control module 2, configured to receive the current control instruction and discharge according to the current control instruction; The shape memory alloy 4 is connected to the discharge module 3 and is used to generate heat after being energized. In the heating state, the shape memory alloy 4 is deformed into a preset shape.

[0024] The information collection module 1 includes: at least one of an environmental status sensor, a voice recognition device, and a Bluetooth device; The environmental state sensor collects the environmental state change as the environmental instruction, the voice recognition device collects the user's voice signal, and the Bluetooth device obtains the adjustment instruction issued by the mobile terminal.

[0025] In the present invention, by collecting information through various channels, it is possible to control the shape memory alloy 4 in various ways, thereby meeting the user's demand for playability and control.

[0026] Specifically, the environmental status sensors include: at least one of a light sensor, a posture sensor, and an ambient temperature sensor; The light sensor is used to collect the brightness of the light inside the vehicle, the posture sensor is used to collect the posture change information of the vehicle and the user, and the ambient temperature sensor is used to collect the ambient temperature information inside the vehicle. Among them, the brightness of the light, the posture change information of the vehicle and the user, and the ambient temperature information inside the vehicle can all be used as environmental instructions.

[0027] The light brightness inside the car is collected through a light sensor. When the light brightness exceeds a set threshold, the shape memory alloy 4 is controlled to change its shape. The posture sensor collects vehicle status information. For example, when the car door is opened, the shape memory alloy 4 gradually changes its shape, coordinating with the changes in the interior lighting to create a sense of ceremony and a personalized welcoming experience. Alternatively, the posture sensor inside the car detects that the user has made specific gestures in the car, and can also control the shape memory alloy 4 to gradually change its shape to show a special pattern.

[0028] In the present invention, the speech recognition device includes: A microphone, for collecting a user's voice signal through the microphone; A voice conversion unit, which converts the user's voice signal into text information; The speech recognition model uses the speech recognition model to understand the semantics of text information and generate voice commands.

[0029] Specifically, the voice signal emitted by the user is collected through the microphone in the car, and the voice signal is converted into text information through the voice recognition model built into the voice conversion unit. After the voice understanding of the text information, language instructions for controlling the shape memory alloy 4 can be formed.

[0030] The Bluetooth device establishes a Bluetooth connection with the user's mobile terminal, receives adjustment instructions issued by the user's mobile terminal, realizes multi-terminal control, and provides users with a richer interactive experience.

[0031] In the present invention, the control module 2 includes: On-board controller and current controller; The vehicle-mounted controller is electrically connected to the information acquisition module 1, and receives various types of command information and processes the commands through the vehicle-mounted controller to generate adjustment signals; The current controller is electrically connected to the vehicle controller and generates a current control instruction according to the adjustment signal. The discharge module 3 is electrically connected to the current controller; the discharge module 3 discharges based on the current control instruction generated by the current controller.

[0032] Specifically, the onboard controller receives all command information collected by the information acquisition module 1, parses and normalizes the command information, converts multiple commands, and generates a control signal that can be recognized and read by the current controller. After receiving the control signal, the current controller controls the discharge module 3 to discharge according to the control signal. In this application, different shape memory alloys 4 can be controlled independently without affecting each other, so that the shape memory alloys 4 exhibit different states.

[0033] The shape memory alloy 4 is electrically connected to the discharge module 3, and the current discharged by the discharge module 3 generates heat in the shape memory alloy 4; The shape memory alloy 4 is deformed into a preset shape under heat driving.

[0034] In this invention, nickel-titanium alloy (Nitinol) is selected as the SMA material because of its high elasticity, high energy output density, and good shape memory properties, making it well-suited for the high-frequency use environment of automotive interiors. At the same time, high-temperature resistant embroidery materials (such as cotton thread and satin) are selected to ensure that the embroidery material will not be damaged by high temperatures during the SMA actuation process. Depending on the requirements of the embroidery pattern, the SMA wire is designed into a bidirectional external frame or internal skeleton structure. For example, in a floral pattern, the SMA wire is distributed along the edge of the petals to form a dynamically opening and closing skeleton. A couching stitch is used to secure the SMA wire to the edge or inside of the embroidery, ensuring its close connection with the embroidery thread while maintaining the flatness of the embroidery surface.

[0035] SMA deformation is driven by Joule heating. When current passes through the SMA wire, heat is generated, causing it to reach its phase transition temperature, thereby deforming into the preset shape. The SMA drive current is independently controlled by region. For example, the opening and closing of petals can be divided into two independent circuits, controlling the left and right SMA wires respectively. Furthermore, an overheating protection mechanism is integrated into the shape memory alloy 4 to prevent damage to the SMA wire or embroidery material due to excessive current.

[0036] Specifically, the SMA forming and fixing process involves heating the SMA wire in a muffle furnace at 500°C for 15 minutes to achieve high-temperature setting, followed by rapid cooling to impart memory. During the embroidery process, the SMA wire is secured to the edges or interior of the embroidery pattern using thread-attaching. The securing points must be evenly distributed to ensure a smooth, wrinkle-free, and unevenly deformed embroidery structure.

[0037] In the process of combining embroidery materials with SMA, high-temperature resistant embroidery materials such as cotton thread and satin are selected to ensure that they will not be damaged by high temperature during the SMA driving process; the SMA wire is wrapped in the embroidery wire using long and short stitches or flat stitches to ensure a smooth embroidery surface while allowing the SMA wire to move freely during deformation. The shape memory alloy is wrapped in the embroidery wire by stitching to form a set shape at a preset position.

[0038] The present invention provides a dynamic interactive system for automobile interiors based on a shape memory alloy 4. After acquiring instruction information, a control instruction is generated. The control instruction controls the discharge module 3 to discharge the shape memory alloy 4, generating heat inside the shape memory alloy 4, so that the shape memory alloy 4 returns to a preset shape. By integrating the shape memory alloy 4 with embroidery, the automobile interior becomes more interactive, and the shape memory alloy 4 can have a longer service life, thereby meeting user needs.

[0039] An embodiment of the present invention also provides a vehicle including the aforementioned shape memory alloy-based automotive interior interaction system. By installing the shape memory alloy-based automotive interior interaction system within the vehicle, a discharge module discharges electricity into the shape memory alloy upon a change in environmental conditions or when a user's voice signal is received. This current generates heat within the shape memory alloy, which then deforms into a pre-set shape under the influence of heat. This provides a new interactive aesthetic solution for smart car interior design, satisfying user demands for both personalization and a sense of technology.

[0040] refer to Figure 2 The present invention also discloses a dynamic interaction method for automobile interior based on shape memory alloy, comprising: Step 100: Obtain instruction information through the information collection module; Step 200: parsing the command information through a control module and generating a current control command; Step 300: Control the discharge module to discharge into the shape memory alloy based on the current control instruction; Step 400: The shape memory alloy generates heat after being energized. In the heated state, the shape memory alloy is deformed into a preset shape.

[0041] In one specific embodiment, a shape memory alloy is designed into a floral pattern. Within the floral pattern, SMA wire is distributed along the edges of the petals, and current is used to drive the petals to naturally open and close, simulating the dynamic effect of a blooming flower. In geometric patterns, SMA wire is embedded in the pattern edges, and actuation allows for dynamic changes in the pattern contours, enhancing visual impact.

[0042] Calculate the required drive current and voltage based on the cross-sectional area and length of the SMA wire. Typically, a low-voltage (5–12V) DC power supply is used to avoid overheating and potential safety hazards. Experimentation is required to determine the optimal current and drive time to ensure the SMA wire deforms quickly while avoiding overheating and damage to the embroidery material.

[0043] Dynamic embroidery actions are divided into multiple independent control units. For example, in a floral pattern, the left and right petals are controlled by two separate circuits, allowing them to open and close independently. In interactive design, dynamic embroidery actions are triggered by temperature sensors or touch switches. For example, as the temperature inside a car rises, the embroidered petals gradually unfold, and the interior lighting changes to warm tones, creating a cozy atmosphere.

[0044] Integrate dynamic embroidery into your car's dashboard or door trim as a welcome device. When the door opens or the vehicle starts, the embroidered petals gradually unfold, aligning with the interior lighting to create a sense of ceremony. The dynamic embroidery can be triggered by vehicle start signals or temperature changes, achieving intelligent interaction with the vehicle's interior environment.

[0045] Through practical experiments, the durability of different embroidery materials (such as cotton and satin) at SMA drive temperatures was tested to select the optimal combination. By adjusting the SMA wire length and drive current, the deformation amplitude and speed were optimized to ensure a natural and smooth dynamic effect. Using a single petal as a prototype, the opening and closing speed and amplitude were tested at different currents to ensure smooth and lag-free movement. Dynamic embroidery was integrated into real-world applications (such as automotive interiors) to test its stability and durability under frequent use.

[0046] In this invention, nickel-titanium alloy (Nitinol) is selected as the SMA material due to its high elasticity, high energy output density, and excellent shape memory properties, making it well-suited for the high-frequency use environment of automotive interiors. Furthermore, high-temperature-resistant embroidery materials (such as cotton thread and satin) are selected to protect the embroidery material from heat damage during SMA actuation. The SMA filament is designed as a bidirectional external frame or internal skeleton structure and embedded in the automotive interior embroidery pattern (such as instrument panel decoration and door panel embroidery). This ensures that the embroidery structure remains naturally smooth during dynamic deformation, without wrinkles or uneven deformation.

[0047] When combining movement and stillness, the dynamic elements (such as petals and leaves) are embroidered using SMA skeletons and three-dimensional embroidery technology, while the static elements (such as the background pattern) retain traditional flat embroidery techniques, enhancing the visual layering and coordinating with the overall design style of the car interior. By leveraging the smooth deformation properties of SMA, the dynamic beauty found in nature (such as the blooming of petals and the swaying of leaves) is simulated, bringing the car interior embroidery to life and enhancing the artistic and technological sense of the interior environment.

[0048] The SMA filament is secured within the embroidery using a coching stitch and long-short stitch method, ensuring structural stability during dynamic deformation while retaining the aesthetic integrity of traditional embroidery, meeting the high-end customization requirements of automotive interiors. By optimizing the SMA molding process (such as high-temperature setting) and drive parameters (such as current and time), the dynamic embroidery maintains stability and fatigue resistance under high-frequency use, adapting to the long-term use environment of automotive interiors.

[0049] The linkage between intelligent driving and automotive scenarios is based on the phase change temperature of SMA (45–80°C), and a low-voltage (5–12V) driving circuit is designed. The SMA deformation is driven by Joule heat to ensure safety and energy efficiency, which is suitable for the requirements of automotive electrical systems.

[0050] This invention uses Arduino open-source hardware as the control core, independently controlling the SMA drive current in each region to achieve precise dynamic embroidery deformation (such as petal opening and closing, contour transformation), and synchronizes with scenarios such as car starting and door opening and closing. Dynamic embroidery actions are triggered by a temperature sensor or touch switch and synchronized with the ambient lighting effects inside the vehicle. For example, when the car door is opened, the embroidered petals gradually unfold, and the interior lighting changes to warm tones, creating a warm and welcoming atmosphere.

[0051] In specific application scenarios, dynamic embroidery can be integrated into car dashboards or door interior panels as a welcome feature. When the door is opened or the vehicle starts, the embroidered petals gradually unfold, aligning with the changing interior lighting to create a sense of ceremony and a personalized experience. Dynamic embroidery actions are triggered by changes in the interior temperature. For example, as the interior temperature rises, the embroidered petals gradually unfold, and the interior lighting changes to red, creating a warm visual experience. The dynamic embroidery design not only enhances the interior aesthetics but also enhances the driver's comfort and sense of ceremony through multi-sensory interactions (such as lighting and dynamic embroidery), enhancing the overall driving experience.

[0052] This invention transcends the static limitations of traditional embroidery by integrating dynamic and static elements. Leveraging the intelligent deformation properties of SMA, this technology achieves natural and fluid dynamic effects (such as blooming petals and swaying leaves) while preserving the aesthetic integrity of traditional embroidery and enhancing the artistic and technological feel of automotive interiors. Intelligent Interaction: By triggering SMA deformation through temperature, current, or touch, automotive interior embroidery is intelligently linked to the in-car environment (such as lighting and temperature). For example, when a car door is opened, embroidered petals gradually unfold, aligning with the changing interior lighting to create a ceremonial and personalized welcome experience. Lightweight and Highly Compatible: Leveraging the slenderness and high elasticity of SMA, it seamlessly integrates with the embroidery material, avoiding the bulk and weight issues associated with traditional drive materials (such as motors and electronic components), ensuring lightweight and aesthetically pleasing interior design. Durability and Stability: By optimizing the SMA molding process and drive control, the dynamic embroidery maintains stability and fatigue resistance under high-frequency use, adapting to the long-term use environment of automotive interiors. Dynamic embroidery is widely used in car interiors (such as dashboards, door panels, and seat trims), providing a new interactive aesthetic solution for smart car interior design, meeting users' needs for personalization, technology, and cultural connotations.

[0053] Dynamic interaction within automotive interiors, based on shape memory alloys, enhances dynamic expressiveness: SMA actuation enables natural and smooth deformation (e.g., petals blooming, leaves swaying), bringing traditional embroidery to life. Automotive interior innovation: Dynamic embroidery is linked to ambient lighting effects within the vehicle, enhancing the welcoming experience and personalizing the experience. Process compatibility: While preserving the aesthetics of traditional embroidery, it also incorporates modern technology, expanding the application of embroidery within smart car interiors.
