Description

Technical Field

[0001] The present invention relates to the technical field of vehicle display, and in particular to an integrated vehicle structure. Background Art

[0002] With the development of intelligent connected vehicles and exterior display technology, the demand for integrated display modules on vehicle exteriors continues to grow. Traditional exterior vehicle panels, primarily made of metal or composite materials, provide structural support and collision energy absorption but lack video display capabilities. Conventional display screens, often installed inside the vehicle or as standalone advertising devices, fail to balance structural strength, lightweight design, and display functionality.

[0003] Directly integrating the display module into the vehicle bodyshell presents multiple technical challenges: First, it must meet the stringent automotive regulatory requirements for strength, rigidity, and collision energy absorption to ensure safety under collision, vibration, and environmental conditions. Second, it must ensure the stability of the display function or prevent controlled failure under long-term operation, temperature cycling, and impact conditions to avoid secondary risks such as fragmentation and scattering. Furthermore, achieving an inseparable, integrated design between the display module and the load-bearing structure, while simultaneously meeting regulatory certification and durability requirements through lightweight, high-strength materials, energy-dissipating structures, and edge-sealed locking methods, remains a key challenge in current vehicle display integration design. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: an integrated vehicle structure, a display module, and a load-bearing structural module forming an inseparable, integrated composite structure. This module directly forms part of the vehicle body shell and withstands structural loads under vehicle operation and collision conditions. The composite structure meets the strength, stiffness, and energy absorption requirements of vehicle safety regulations, ensuring that the display module maintains functional stability or experiences controlled failure under regulatory testing and actual operating conditions, while also reducing mass per unit area through lightweight design.

[0005] The control system can correct the distorted display content and output it to the curved display screen of the vehicle body for display, so that the visual content of the curved display screen of the vehicle body and the flat display screen form a continuous and smooth transition, ensuring that the visual effect of the display content on the entire vehicle body is normal and without significant deformation.

[0006] Furthermore, the display module also includes a vehicle shell carrying display components, including: A) a display function layer for presenting dynamic images; B) a load-bearing structural layer, which forms an integrated composite shell with the display function layer, directly constituting the target vehicle outer cover in the installed state and serving as part of the main load path of the vehicle body to withstand static loads, driving loads and collision / pedestrian impact loads; C) a lightweight and high-strength support system, including at least one of a sandwich core material, a honeycomb / grid / sash or a fiber-reinforced laminate, for limiting the working of the display function layer while meeting the regulatory stiffness, strength and energy absorption indicators. strain; D) Energy absorption and impact diffusion unit, integrally formed with the load-bearing structure layer or fixed at multiple points, for gradually dissipating energy along non-critical display areas and support paths during impact; E) Edge mechanical locking and sealing structure, arranged around the periphery of the component, forming a stepped / undercut / clamp-type bite and moisture barrier with the body frame or outer covering; wherein, the display function layer and the load-bearing structure layer are inseparable in the installed state and cooperate to meet the load-bearing and energy management performance required for vehicle safety certification, and maintain normal display function or enter a controlled failure state within the certification working conditions without scattering damage. The lightweight and high-strength support system is a sandwich structure: a honeycomb / foam / triangular truss / topologically optimized lattice core material is sandwiched between the outer transparent / translucent load-bearing panel and the inner load-bearing backplane, and an optical / mechanically compatible intermediate layer is provided between the display function layer and the outer load-bearing panel. The outer load-bearing panel is selected from: chemically tempered glass, high-toughness transparent panels of polycarbonate (PC) or PMMA, or composite transparent laminates; the inner load-bearing backplane is selected from: CFRP / GFRP laminates, aluminum / magnesium alloy panels, or steel panels. The energy absorption and impact diffusion unit is at least one of the following: a) a core material with gradient thickness / density; b) a trigger-type crush bead or crush channel; c) a corrugated / pleated controllable buckling zone; d) a breakable bridging rib for limiting cracks and diverting stress. The display functional layer is one or a combination of flexible OLED, flexible Micro-LED, Mini-LED backlight flexible LCD, or dot-matrix LED. The neutral layer tuning structure positions the functional layer at or near the bending neutral plane to reduce peak strain. A modulus gradient adhesive layer / gel optical coupling layer is provided between the display functional layer and the load-bearing structural layer. Its out-of-plane shear modulus is lower than that of the load-bearing layer, while its in-plane bonding strength is higher than a preset threshold, thereby achieving both optical coupling and strain isolation. The edge mechanical locking and sealing structure includes a stepped-undercut composite interface, a circumferential clamping ring or a perforated rivet strip, and is combined with a labyrinth sealing channel and a hydrophobic / anti-icing coating to inhibit water vapor intrusion and low-temperature freezing and peeling. A rigid island-flexible bridge or serpentine conductor layout is used for display pixel electrical interconnection, and strain limiters are provided in the bridge area to ensure that the electronic interconnection remains electrically intact or safely disconnected under structural loads and certification impacts. The load-bearing structure layer is connected to the body frame through controllable deformation connectors (slip grooves, oblong hole limiters, energy-absorbing brackets) to match the vehicle's energy management path during a collision and avoid brittle shedding.The exterior surface of the component meets regulatory requirements for pedestrian head / leg impact and exterior component fixity for the target vehicle's corresponding locations, and its residual load-bearing capacity after regulatory operating conditions is no less than that of a similarly sized metal panel. Integrated structural health monitoring sensors (strain, acceleration, fiber Bragg grating, or piezoelectric) and a controlled failure controller trigger display dimming / power-off, pixel limiting, and external alarms when impact / buckling exceeding a threshold is detected. The component directly replaces the original body panel in the door, fender, trunk lid, front hood, or bumper. Retractable bridging straps / deployable mechanisms are incorporated across the seam to maintain load-bearing and electrical continuity during opening and closing. The transparent load-bearing panel's Vickers / rocker impact toughness and surface compressive stress meet preset thresholds, and it is irreversibly connected to the inner load-bearing backplane through co-curing / in-mold integration. The sandwich core or lattice features a zoned and segmented design: a low-density energy-absorbing core is used in the pixel area, while a high-modulus lattice is used in the wiring / frame area to achieve functional-structural synergy. The electromagnetic shielding / thermal management layer of the component is conformally arranged with the load-bearing structure, including a transparent conductive layer and a heat dissipation channel, and its stiffness contribution is included in the overall load calculation. It also includes an integrated manufacturing and installation method for the vehicle shell to support the display component, including: S1) obtaining the regulatory working conditions and main load path of the target vehicle body part, and determining the load-bearing and energy absorption targets; S2) designing the interlayer / frame layout and neutral layer position of the outer transparent load-bearing panel-core material-inner load-bearing backplane, and determining the layers of the display function layer and the modulus gradient layer; S3) using co-curing / in-mold embedding / hot pressing lamination to make the display function layer and the load-bearing structure layer an inseparable whole; S4) mechanically locking and labyrinth sealing the molding edge and assembling controllable deformation connectors; S5) verifying the load-bearing and energy absorption performance through regulatory equivalent load tests or simulations, and calibrating the controlled failure threshold and display degradation strategy; S6) installing the component on the vehicle and verifying the functional and structural consistency under the vehicle certification working conditions (including pedestrian protection). S3 is performed under vacuum or an inert atmosphere to improve interfacial bonding strength, and S5 utilizes a combination of physical testing and digital prototyping for verification and is recorded as assembly control parameters. Furthermore, the display module also includes an integrated load-bearing display structure, comprising: a display module for displaying dynamic images on the vehicle exterior; and a load-bearing structure module, which forms an inseparable, integrated composite structure with the display module, directly forming part of the vehicle exterior and bearing the structural loads during vehicle operation and collision conditions. The integrated composite structure simultaneously: a) provides structural strength, stiffness, and collision energy absorption performance that meet vehicle safety regulations; b) maintains functional stability or controlled failure of the display module during regulatory testing and actual vehicle operation; and c) possesses a lightweight support system, resulting in a lower mass per unit area than traditional metal exterior components of equivalent load-bearing capacity. The load-bearing structure module comprises fiber-reinforced composite materials, metal lattices, honeycomb interlayers, foam core materials, or combinations thereof. The display module is selected from flexible OLED, Micro-LED, Mini-LED backlit liquid crystal displays, dot-matrix LEDs, electrophoretic displays, or combinations thereof.The load-bearing structure module and the display module are combined by in-mold co-curing, hot-pressing integral molding, metal insert direct connection or co-molding. The residual load-bearing capacity of the integrated composite structure under the vehicle front, side and rear collision regulations is not lower than that of traditional metal covering parts of the same size. Under collision or external impact conditions, the energy absorption area of ​​the load-bearing structure module deforms preferentially, thereby reducing the local strain peak of the display module. The integrated composite structure is used in the doors, fenders, trunk lid, front hood or bumper parts of the vehicle. A high-toughness transparent protective layer is provided on the outer surface of the display module, and the protective layer matches the neutral layer of the load-bearing structure module to reduce bending and impact stresses. The load-bearing structure module is fixed to the vehicle frame by energy-absorbing connectors, which control the load transfer path during a collision. A modulus gradient bonding layer is provided between the display module and the load-bearing structure module to suppress interface peeling. Also included is a method for an integrated load-bearing display structure, comprising: a) designing the load path and safety regulatory operating conditions of the target vehicle shell; b) designing the display module and the load-bearing structure module into an integrated composite structure according to the load path; c) inseparably combining the display module and the load-bearing structure module through in-mold embedding, co-curing or thermoforming; and d) verifying the load-bearing performance and display function under vehicle safety regulatory test conditions.

[0007] Furthermore, the display module also includes a shell that carries a display assembly, including: A) a display function layer for presenting dynamic images; B) a load-bearing structural layer, which forms an inseparable integrated composite structure with the display function layer and directly serves as the load-bearing part of the vehicle exterior when installed, bearing loads including static loads, driving loads, environmental impacts and collision loads; C) an energy management unit, arranged in the thickness or in the surface of the integrated composite structure, for impact diffusion and progressive energy absorption during collisions or flying object impacts, and for bypassing peak stresses around key display function areas; D) a structural connection and deformation limiting unit, which connects the integrated composite structure to the vehicle body frame so that the assembly can cooperate with the vehicle body frame to bear loads under applicable vehicle safety certification conditions and meet regulatory requirements; wherein the interface between the display function layer and the load-bearing structural layer is a structural-functional coupling interface, which maintains stable display performance during normal vehicle driving and certification conditions, and enters a controlled failure mode under extreme loads to maintain structural energy absorption continuity. The load-bearing structural layer is at least one of a sandwich, honeycomb, or lattice lightweight system, comprising: a) a faceplate: a metal faceplate or a fiber-reinforced composite faceplate; b) a core: a metal or non-metallic honeycomb, foam, 3D woven, or adjustable Poisson's ratio lattice; and c) a backplane: a metal plate or composite laminate. The backplane is co-cured or in-mold embedded with the display functional layer to form an integral whole. The display functional layer is a flexible OLED, Micro-LED, Mini-LED backlit flexible LCD, dot-matrix LED, or a combination thereof, and is equipped with an outer transparent impact-resistant protective layer (tempered glass or hard-coated polycarbonate / transparent composite panel), which also serves as the outer surface panel of the load-bearing structural layer. The structure-function coupling interface utilizes a modulus gradient bonding system and / or a mechanically meshed microstructure to inhibit delamination and interlayer slip under the coupled effects of out-of-plane impact and in-plane tensile bending. The energy management unit includes at least one of the following: trigger ribs / crush beads, controllable wrinkling zones, a gradient thickness layer, microbuckling-inducing textures, and crack-blocking islands / ribbons. The structural connection and deformation limiting elements include a displacement-limiting hole / long circular hole-positioning cone combination, energy-absorbing supports, sliding grooves with damping blocks, and fracture-triggering connectors. Their configuration limits the component's travel relative to the frame and establishes the load path. A neutral layer tuning structure is implemented. Through thickness / modulus distribution and prestressing design, the display functional layer or its key sublayers are positioned within the ±Δ range of the bending neutral plane to reduce operating strain. The exterior surface is coated with an optical and weather-resistant composite coating (anti-scratch / anti-glare / hydrophobic / anti-icing / UV-resistant), which, along with the protective layer, jointly withstands surface shear and micro-impacts. The load-bearing structural layer utilizes a hybrid metal-composite material: metal lattices / ribs are positioned in high-stress areas, while fiber-composite laminates are used in low-stress areas to achieve both stiffness-mass performance and energy absorption. Where components span openings and closing elements such as doors and trunk lids, a cross-gap bridging structure is implemented. This structure comprises a deployable lattice / serpentine conductor and a corrugated cover layer, with floating terminals providing simultaneous compliance of the electrical and structural connections.The bridging bands of the gap structure feature equivalent zero-Poisson's ratio corrugations or four-bar deployable units, ensuring that the strain during opening and closing cycles remains within preset thresholds. An integrated strain-acceleration-temperature sensor and control unit triggers controlled degradation / shutdown and activates the energy absorption pathway upon detecting abnormal impact or excessive deformation. The integrated composite structure demonstrates in-plane residual stiffness and impact energy absorption performance meeting preset thresholds in drop weight / ball impact and three-point bending tests as specified in the specifications, with the functional layer maintaining the ability to exhibit or enter controlled failure without flaking. The edges utilize a stepped-undercut composite edge / continuous clamping ring / perforated rivet strap / magnetic pressure flange to enhance edge peeling and rock impact resistance. The component is installed as a vehicle exterior component on at least one of the door panels, fenders, hood, trunk lid, or bumper, and directly participates in load-bearing and energy absorption in the vehicle's certification conditions, including pedestrian protection, frontal, side, and small offset. The invention also includes a method for housing a display assembly, including: S1) establishing the load path and certification conditions for the target vehicle body area; S2) designing the panel-core-backplane / frame layout and energy management unit location for the load-bearing structural layer; S3) integrating the display functional layer and the load-bearing structural layer into an inseparable, integrated composite structure through co-curing, in-mold embedding, or metal overmolding; S4) integrating the structural connections and deformation limiting elements and performing in-situ calibration; S5) jointly verifying impact resistance, bending resistance, edge peeling resistance, and display stability according to the methods specified in the instructions; and S6) assembling the assembly with the vehicle body frame to ensure that the assembly can support the frame under certification conditions and meet applicable vehicle safety regulations. S3 is conducted under vacuum / inert atmosphere, and the bonding interface utilizes a dual-adhesive modulus gradient and surface roughening / microporation to synergistically enhance interlayer toughness. S2-S5 utilize a closed-loop digital simulation-testing process to optimize the energy management unit and connection travel based on the boundary conditions of a pedestrian's head / leg impactor and the vehicle's collision. The energy absorption path at the location of the component is guided by the longitudinal / transverse beams of the vehicle body, the door anti-collision beams or the bumper beams, and in the event of an abnormal impact, the component enters a controlled failure to maintain the overall energy absorption continuity and prevent the outer surface from causing dangerous fragmentation and falling off.

[0008] Furthermore, the display module also includes an integrated component, comprising: A) a display functional layer for presenting dynamic images; B) a load-bearing structural layer, which is co-cured, in-mold laminated, and metallurgically or chemically bonded with the display functional layer to form an inseparable integrated composite structure. When installed, the composite structure directly replaces the outer covering of the target vehicle portion and participates in the vehicle body load path; C) an energy absorption and impact diffusion unit, arranged in the load-bearing structural layer and / or its connection area with the vehicle body, for inducing progressive crushing and energy diffusion under pedestrian protection, low-speed collision, and regulatory collision conditions; D) a peripheral load-bearing connection member, including a peripheral flange / ear plate, an oblong hole / sliding groove, and a limiting surface, for forming a multi-point rigid-compliant hybrid connection with the vehicle body frame, limiting interfacial delamination under static load, vibration, and thermal cycling, and providing controlled deformation during collision. The components A) to D) cooperate to enable the component to simultaneously meet the following requirements: as an outer covering, it can withstand in-plane / bending / shear loads and provide the required energy absorption capacity per unit area, and the display functional layer can maintain normal operation or enter a controlled failure state under regulatory collision conditions. The load-bearing structural layer is a sandwich, honeycomb, or lattice structure, or a combination thereof, comprising an outer transparent / translucent load-bearing skin, an inner structural skin, and a honeycomb core, foam core, or topologically optimized lattice core located therebetween. The display function layer is a flexible OLED, flexible Micro-LED, Mini-LED backlit flexible LCD, dot-matrix LED, or a combination thereof. A transparent, high-toughness protective layer (tempered / chemically strengthened glass, PC, PMMA, or a laminate thereof) provides impact and scratch resistance to the outer surface. A modulus gradient adhesive layer / interlayer is positioned between the display function layer and the load-bearing structural layer, with a gradual change in elastic modulus or loss factor along the thickness direction to inhibit interfacial delamination caused by thermal cycling and impact. The energy absorption and impact diffusion unit includes at least one of the following: a triggerable crush bead / rib, a corrugated trigger zone, a gradient thickness zone, a controlled crack guiding groove, and a releasable sacrificial connection point. A stepped, undercut, or dovetail composite interlocking interface is formed between the peripheral load-bearing connection member and the vehicle body frame, with a tangential slip-normal limiter mechanism to compensate for thermal expansion and dynamic vehicle body deformation. The equivalent neutral layer position of the outer load-bearing skin and the display function layer is configured by thickness / modulus or prestressed, so that the display function layer is located in a section close to the neutral plane to reduce the bending peak strain. The core material is aluminum / magnesium alloy honeycomb, thermoplastic / thermosetting foam, sandwich lattice shell or 3D printed lattice, and high-density inserts are locally filled in high-stress areas (hinges, locks, collision beam connection points). The display function layer integrates strain / acceleration / temperature sensors and shutdown circuits. When triggered by a collision, it enters a controlled shutdown or brightness reduction mode to avoid glare and protect the electric drive. The equivalent bending stiffness EI of this component is not less than 0.8 times that of the metal outer plate of the same size, and the energy absorption per unit area SEA is not less than 0.7 times that of the metal outer plate within the specified crushing displacement. The outer surface protective layer has a hard coating / anti-glare / hydrophobic anti-icing composite coating and also serves as part of the load-bearing skin.When crossing opening and closing areas such as doors or trunk lids, the peripheral load-bearing connecting members and the energy absorption and impact diffusion units together form a controlled turning / hinge zone to maintain display and load-bearing functions during opening and closing and collisions. The integrated composite structure can be verified for interface continuity through non-destructive testing (ultrasound / infrared thermal imaging / impedance spectroscopy) to meet regulatory requirements for endurance cycle integrity. The interface bonding method is at least one of co-curing (composite materials) / in-mold injection coating / brazing or surface-activated chemical bonding, and does not rely on removable fasteners to maintain display-load-bearing integration. In the vehicle, at least one exterior covering of the door, fender, trunk lid, front hood, or bumper is a load-bearing integrated display assembly, and is connected to the vehicle body frame at multiple points via the peripheral load-bearing connecting members, allowing the assembly to directly participate in energy absorption and stiffness maintenance in regulatory collision and pedestrian protection conditions. The vehicle controller is connected to the sensor / shutdown circuit to implement controlled display shutdown and fault isolation when a collision trigger or high strain rate event is detected. The method also includes manufacturing methods for integrated display components, including: S1) determining the layout and thickness of the skin / core / connector based on the load paths and regulatory conditions of the target vehicle body area; S2) co-curing / in-mold lamination / surface-activated bonding of the display functional layer and the load-bearing structural layer to form an inseparable integrated composite structure; S3) forming an energy-absorbing and impact-diffusing unit, and constructing a stepped-undercut / dovetail composite interlocking and slip-stop mechanism at the periphery; S4) prestressing / thickness tuning of the neutral layer position and interface modulus gradient; and S5) calibrating the EI and SEA through non-destructive testing and standardized crash component testing until target performance is achieved. S2 is performed under vacuum bagging, automated layup, RTM, or autoclave conditions, while the triggering feature of S3 is achieved through localized thinning, prefabricated crush ribs, or trip points. The comparison benchmark for S5 is a metal exterior panel sample with the same geometry and installation conditions, and its EI and SEA are used as proportional indicators. When a pedestrian protection or collision trigger signal is detected, the shutdown circuit in the component turns off the display light and isolates the power / signal of the impacted partition within T≤10ms, while allowing the energy absorption and impact diffusion unit to collapse / trip to protect pedestrians and maintain the continuity of the vehicle body load.

[0009] Furthermore, the display module also includes a display-integrated vehicle exterior covering, which includes, arranged in order from the outside to the inside: a) an outer surface load-bearing panel, which is a transparent or translucent structural panel for directly bearing the environmental and structural loads of the vehicle body exterior covering; b) a display functional layer, which is arranged on the inner side or in the outer surface load-bearing panel and has a light-emitting or dimming function to present dynamic images; c) an encapsulation / isolation layer for environmentally and electrically isolating the display functional layer; d) an energy absorption core, which is a honeycomb, foam, three-dimensional lattice or layered origami structure with a spatial modulus / density gradient; e) an inner surface load-bearing panel, which forms a sandwich laminate with the outer surface load-bearing panel and the energy absorption core; f) a peripheral layer around the edge of the sandwich laminate. The circumferential load-bearing closed-loop structure is a closed-section frame or an equivalent closed loop composed of multiple closed side beams and corner connectors, used to circumferentially channel vehicle external loads and collision loads into the vehicle body reference structure. The sandwich laminate's equivalent neutral layer position is tuned through structural configuration, positioning the display functional layer within or adjacent to the neutral layer's strain safety belt. The energy-absorbing core and circumferential load-bearing closed-loop structure collaborate to form a controlled collapse and energy dissipation path, enabling the outer covering to provide targeted energy absorption and strength in pedestrian collisions, low-speed scrapes, and impacts at specified locations within specified energy levels. Furthermore, when a preset strain / acceleration threshold is exceeded, the display functional layer is electrically isolated from its power / signal circuits via a fail-safe disconnect unit. The display functional layer is one or a combination of the following: flexible / semi-flexible Micro-LED, OLED, Mini-LED backlight liquid crystal, dot-matrix LED, electrophoretic / liquid crystal dimming layer, or micro-projection coupled lightguide. The outer surface load-bearing panel is chemically tempered glass, transparent polycarbonate, transparent fiber-reinforced composite material or ceramic transparent body, and its surface is provided with anti-scratch / anti-glare / hydrophobic coating. The energy absorption core is a gradient honeycomb or three-dimensional lattice, and its unit size, wall thickness or density gradually changes from the center area to the edge area to achieve edge anti-peeling and energy absorption matching. The circumferential load-bearing closed-loop structure is a closed thin-walled frame, and is connected to the body frame through a decoupling connection of a positioning cone + oblong hole to retain tangential micro-slip during assembly and thermal expansion but ensure circumferential load transmission. It also includes edge mechanical locking and modulus gradient adhesive system: the side close to the sandwich laminate is a low modulus high elongation adhesive, and the side close to the closed-loop structure / body is a structural adhesive. The two form a stepped-undercut composite interface to suppress edge warping and peeling. A neutral layer tuning sublayer or prestressed layer is provided between the display functional layer and the energy absorption core to place the display pixels / interconnections within the curved neutral band. In-plane reinforcement of the sandwich laminate is provided by ribs / fiber tapes arranged in a uniform stress pattern, with localized compliance hinges at points of sudden curvature to prevent stress concentrations. Fail-safe disconnect elements, including strain-activated fuses, pressure-sensitive disconnect connectors, or insulating bursting fragments, isolate the display / power system from the main wiring harness during a crash or large deformation event.The sandwich laminate's primary function is load-bearing and energy absorption for the vehicle exterior, and its secondary function is display. Through a three-component configuration of a closed-loop structure, core gradient, and neutral layer tuning, these two functions coexist within the same component without interfering with each other. Trigger collapse beads / crush trigger ribs are positioned between the closed-loop structure and the vehicle body's base structure to achieve a controlled platform force-displacement response. The display function layer utilizes tiled micromodules interconnected by flexible bridges. The tile gaps are filled with a high-refractive-index elastic encapsulation to form a continuous light-emitting surface and provide crack isolation. The inner surface load-bearing panel and the closed-loop structure are integrally formed into an integrated rib-frame-flange configuration, with rib height and rib spacing optimized according to the local load spectrum. A micro-floating island decoupling array or thinning grooves are positioned between the energy-absorbing core and the outer surface load-bearing panel to limit out-of-plane shear in the pixel area. The exterior panels are used for door panels, fenders, rear covers, bumper panels, or a combination thereof, and are connected across the seam by deployable bridges with zero-Poisson or corrugated deployable structures. It also includes a thermal-electric dual-function diffusion layer, which acts as a heat diffuser under normal working conditions and as a crack passivation layer under high strain rates of collision. The outer surface load-bearing panel is partially opaque / translucent, and a closed reinforcement ring is set below the shielded area to span the opening or LOGO light-transmitting area. Corner connection blocks are set at the corners of the closed-loop structure, which are high-ductility metals or toughened composite materials to block the expansion of circumferential cracks at the corners. The outer cover is connected to the body through a replaceable modular mounting seat, and the mounting seat has a built-in vibration isolation-limiting composite pad to keep the display layer strain controlled during driving vibration. The sandwich laminate and closed-loop structure meet the following requirements: under the specified low-speed impact energy level, the peak acceleration and rebound of the outer surface are limited to the preset threshold, and the door seam / fender gap is kept within the allowable tolerance under lateral load. The method also includes a structure-display integrated vehicle exterior component, including: S1) determining the exterior component's load path and target neutral layer position based on the quasi-static / collision load spectrum and curvature field of the target installation location; S2) designing the topology and gradient parameters of the energy absorption core, and simultaneously determining the cross-section and connection points of the circumferential load-bearing closed-loop structure; S3) implementing the ply / material configuration of the sandwich laminate according to S1-S2, and pre-positioning the display functional layer within the neutral layer safety belt; S4) forming the outer surface load-bearing panel and the inner surface load-bearing panel, and co-curing or sequentially bonding them with the energy absorption core, display functional layer, and encapsulation layer; S5) assembling the circumferential load-bearing closed-loop structure and modular mounting base to achieve stepped-undercut edge locking; S6) calibrating the trigger threshold of the fail-safe disconnect unit and conducting component-level and assembly-level impact / bending tests for verification. S1 uses explicit dynamics simulation to optimize pedestrian head and leg impacts and low-speed pole impacts, and uses this to inversely determine the core gradient and trigger rib geometry. The exterior panel's fail-safe disconnect unit, linked to the vehicle's safety controller, disconnects the exterior panel's display from the high-voltage system and maintains electrical isolation when a collision occurs. Deployable bridges in the gap area ensure the display and load-bearing function remain recoverable after door / tailgate opening and closing cycles and minor collisions.

[0010] Furthermore, the display module also includes a structured display assembly for the vehicle shell, which is installed on the outer surface of the vehicle body and serves as an outer covering and a load-bearing / energy-absorbing structure, including: A) a transparent load-bearing panel, located on the outermost layer, which is a transparent / translucent panel with structural strength; B) a display function layer, which is integrally laminated with the transparent load-bearing panel and / or its inner substrate, and is subjected to controlled strain in the working state through neutral layer tuning and viscoelastic transition layer; C) an energy absorption and support core layer, which is located on the inner side of the display function layer, and is a foam, honeycomb, open-cell grid or adjustable negative Poisson's ratio / anisotropic lattice structure with spatial gradient density / strength; D) a back-side load-bearing panel, which is laminated with the transparent load-bearing panel and / or its inner substrate; The load-bearing panels form a sandwich structure to provide bending and in-plane stiffness. E) A load introduction and bypass frame is integrally formed or connected around the perimeter of the active display area, forming the primary load-bearing path to the body-in-white (BIW) and, in the event of a collision or major impact, diverting peak loads through the frame and core layer to the display pixel area. F) A boundary locking and sealing structure forms a composite interface of steps, undercuts, clamps, perforations, rivets, and floating oblong holes around the perimeter. The integrated structure formed by A–F performs the triple functions of covering, load bearing, and energy absorption during normal driving and collision / pedestrian protection conditions defined by vehicle regulations, while maintaining the structural integrity and optical continuity of the display functional layer. The transparent load-bearing panel is one of the following or a laminate: chemically tempered glass, transparent ceramic, polycarbonate (PC), epoxy / acrylic-based transparent composite materials, or index-matched laminates containing transparent reinforcing fibers / metal micromeshes / nanowires. The display functional layer comprises at least one of Micro-LED, flexible OLED, Mini-LED backlit LCD, transparent dot-matrix LED, and electrophoretic display, or a combination thereof; its electrodes comprise at least one of ITO / metal mesh / silver nanowires / graphene. The core layer features a zoned / graded density structure: the surface layer near the potential pedestrian impact zone has a low initial yield strength with a decreasing peak, while the BIW connection zone has a high specific strength zone for load transfer. Triggering wrinkles / controllable brittle fracture ribs are circumferentially positioned to achieve progressive energy absorption. The display functional layer is bonded to adjacent layers via a modulus gradient adhesive system: a low-modulus, high-extensibility adhesive near the display layer and a medium-to-high modulus structural adhesive near the load-bearing layer to limit interlayer shear strain and inhibit interfacial delamination. The load bypass frame comprises annular closed ribs with localized "bridge arch" or "well" reinforcements. Its cross-section and material selection ensure that the maximum principal strain in the active display area is below a preset threshold. The neutral layer is positioned by adjusting the panel thickness and the modulus of each layer, ensuring that the display pixel light-emitting layer is located within or adjacent to the neutral layer within ±Δ, with Δ ≤ 30% of the total thickness. Crack-blocking microstructures are installed along the isostress lines within the display effective area: micro-incisions, circular hole arrays, thinning strips, or transparent micro-ribs, to blunt cracks and divert stress. The peripheral boundary is a composite structure of stepped-undercuts and labyrinth seals, with oblong holes and sliding gaskets providing tangential thermal expansion compensation and normal position limiting.The rear load-bearing panel is connected to the vehicle body via a hybrid joint combining structural adhesive and mechanical connections. Mechanical connections utilize at least one of pull rivets, self-pierce rivets, lock rivets, bolts, or snap fasteners. The core layer utilizes a 3D-printed lattice / origami-developable / zero Poisson's ratio topology, with cell size and wall thickness gradients varying in-plane to match the vehicle body curvature and localized loads. Electrical and thermal management features include a transparent heat dissipation layer / nano-conductive filler, embedded thermal diffusers, microchannels, or a vapor chamber. Microheaters or thermal valves are installed at hotspots to de-icing and defogging, as well as to equalize stress. Sacrificial fuse / tear guides are provided in non-display areas that do not affect the primary viewing area, prioritizing energy release during large impacts and preventing catastrophic damage to the pixel area. The exterior surface of the transparent load-bearing panel features a multifunctional coating that is scratch-resistant, anti-glare, hydrophobic, anti-icing, and anti-fouling. The display layer is formed by a splicing of replaceable micro-tiles / sub-modules. The tile boundaries are infilled with a high-refractive-index elastic encapsulant to create a continuous light-emitting surface and maintain interlayer shear compliance. The module incorporates a network of structural health monitoring sensors (strain, acceleration, fiber optic fiber gate diodes (FBG), or piezoelectric) that collaborate with the control unit to achieve display-structure coordinated control. When extreme operating conditions are detected, brightness is reduced, temperature is increased, or edge preload is adjusted. Materials include aluminum or magnesium alloy panels, steel, CFRP / GFRP, thermoplastic / thermoset composites, transparent ceramic / glass-polymer laminates, or hybrid metal-composite structures. Dynamic opening and closing areas, such as doors and tailgates, are connected via retractable bridging straps / floating terminals / corrugated transition seams to maintain electrical continuity and structural bypass. The electromagnetic compatibility (EMC) shielding layer is implemented using a transparent conductive mesh / nanowire / ultra-thin metal layer and is grounded to the BIW at the perimeter to meet vehicle EMC requirements. The entire module meets the crash and pedestrian protection test requirements of vehicle safety regulations, including structural performance and form constraints for frontal impact, side impact, pedestrian head impact, and external component radius. The method also includes a structured display assembly, including: S1) performing load path and equivalent surface curvature analysis based on the target vehicle model to determine the relative layout and dimensions of the display active area and the load bypass frame; S2) designing the core layer partition / grading density and trigger structure, and determining the neutral layer position and bonding modulus gradient; S3) integrally stacking the transparent load-bearing panel, display functional layer, core layer, and back-side load-bearing panel by co-curing / co-laminating; S4) implementing step-locking and labyrinth sealing around the assembly perimeter, and providing oblong holes / slip gaskets for thermal expansion compensation; S5) mounting the assembly to the BIW using a hybrid joint combining structural adhesive and mechanical fastening, and performing vehicle calibration of strain / stiffness and optical surfaces; S6) setting thresholds and conducting coordinated debugging of the structural health monitoring and thermal management systems.

[0011] Furthermore, the display module also includes an integrated structural display module, including: A) a structure-display sandwich body, which is composed of an outer transparent / translucent load-bearing panel, an inner load-bearing backboard and an energy absorption / support core layer located therebetween; B) a photoelectric functional layer arranged in the sandwich body for displaying dynamic images; C) a main load-bearing ring / load bridging frame arranged around the periphery of the sandwich body and connected to the vehicle body structure, the load-bearing ring and at least two structural nodes of the vehicle body forming a continuous load path; D) a controlled energy absorption trigger feature arranged locally in the sandwich body, which is used to trigger the energy absorption in the event of a collision or The module exhibits a preset force-displacement energy absorption curve under impact conditions; E) a toughened adhesive / neutral layer tuning structure disposed between the photovoltaic functional layer and the adjacent load-bearing layer, positioning the photovoltaic functional layer at or near the neutral plane of the interlayer. When installed in a vehicle, the module serves as both a sheathing and a load-bearing member for the corresponding vehicle body portion, sharing load and energy absorption with the vehicle body under quasi-static bending / torsional loads and regulatory-mandated collision, soft ball / hard pendulum impact, or pedestrian protection conditions, while maintaining the display function above a preset usability threshold. The transparent / translucent load-bearing panel is one of the following, or a laminate thereof: chemically tempered aluminosilicate glass, laminated safety glass, transparent polycarbonate, epoxy / PU, or acrylic-based transparent composite panels. The load-bearing backsheet is one of the following, or a laminate thereof: aluminum / magnesium alloy sheet, titanium sheet, steel sheet, fiber-reinforced plastic (CFRP / GFRP), or metal-composite sandwich panels. The energy absorption / support core layer is one or a combination of honeycomb, corrugated, three-dimensional woven mesh, topologically optimized open-cell lattice, or recoverable foam, and exhibits a modulus / density gradient through the thickness or in-plane. Controlled energy absorption triggering features include microbeaded edge beams, grooves / notches, collapsible units, graded buckling ribs, tear initiation openings, or S-shaped fold lines to define the initial peak force and platform segment. The main load-bearing ring / load bridge frame is connected to nodes such as the vehicle body longitudinal beam, door ring, collision beam, pillar, edge beam, or tailgate frame through a composite connection using riveting / screwing and structural adhesive. Telescopic thermal / electrical isolation gaskets are installed on the ring to isolate thermal and electrical stresses. The optoelectronic functional layer is one or a combination of the following: flexible Micro-LED, flexible OLED, Mini-LED backlit LCD, dot matrix LED, reflective electrophoretic display, and waveguide / projection display layer. The neutral layer tuning structure includes: thickness / modulus configuration, pre-bending / pre-stretching, and soft-hard dual adhesive bonding, so that the optoelectronic functional layer is at or close to the neutral plane and the working strain is limited to a preset range. An anti-peeling frame and a step-down composite interface are set on the outside of the sandwich body, and a labyrinth seal and a hydrophobic / anti-icing coating are used to suppress edge warping and water vapor intrusion. A bypass load bridge / secondary load-bearing rib is set inside the module, which provides a bypass force path for the optoelectronic functional layer in the event of large deformation or local puncture impact to avoid the failure and expansion of the functional layer. The sandwich body adopts a flexible and rigid hybrid multi-domain design: the display effective area is a high-transmittance, controllable destruction domain, the circumferential non-display area is a high-strength constraint domain, and is gradually connected by a transition domain.A transparent conductive layer / EMI shielding mesh and a micro-heating / defogging layer are set in the display effective area, and cooperate with the electrical isolation structure of the main load-bearing ring to ensure electromagnetic compatibility and low-temperature impact resistance. The installation and removal sensitivity of the module is defined as: after the module is removed, the static stiffness or collision energy absorption capacity of the corresponding body part decreases by more than a preset threshold, thereby proving that it is a structural component rather than a decorative part. When the module spans the opening and closing area of ​​the door or tailgate, a structural telescopic bridge is set. The bridge is composed of an expandable lattice / zero Poisson's ratio pleated laminate and a sliding limit seat. It maintains a continuous load path during the opening and closing process and limits the display interconnection strain to a safe area. The energy absorption / support core layer and the load-bearing panel / backplane adopt in-situ foaming / curing molding or co-curing and co-consolidation process to obtain interface toughness and structural integrity. The vehicle bumper assembly also includes a structural display surface, including: a) a structural display module, which serves as the first contact and energy absorption member between the bumper outer cover and the front / rear anti-collision beam; b) an anti-collision beam and an energy absorption box connected to the longitudinal beam; c) a circumferential load-bearing connection chain connecting the main load-bearing ring of the module to the anti-collision beam, fender reinforcement and upper / lower cross beam; wherein, under low-speed collision / soft ball test, the module is responsible for energy absorption and controlled destruction; under high-speed / regulatory collision conditions, the anti-collision beam and energy absorption box take over energy absorption, and the two jointly meet preset regulatory indicators. The module, door ring reinforcement and side anti-collision beam together form a closed load-bearing ring, and under side collision, the module and anti-collision beam cooperate in staged energy absorption. The module, the tailgate inner panel and the surrounding reinforcement frame form a box-shaped section, and local trigger ribs are used to achieve controlled crack-no-fall behavior of the glass / transparent load-bearing surface. It also includes design and manufacturing methods, including: S1) obtaining the load spectrum and regulatory working conditions of the target vehicle body position, determining the main load-bearing ring path and assembly stiffness / energy absorption target; S2) determining the sandwich body formula (panel / core layer / backboard material, gradient and thickness) according to the optical visual effect and structural load-bearing coupling requirements, and placing the optoelectronic functional layer at or near the neutral plane through neutral layer tuning; S3) arranging controlled energy absorption trigger features and bypass load bridges in the display effective area and non-display area; S4) using co-curing / in-situ foaming or secondary lamination to manufacture the sandwich body, and integrally forming the main load-bearing ring / load bridging frame; S5) assembling the module to the vehicle body structure node through composite connection to complete the circumferential load-bearing connection chain; S6) calibrating and iteratively adjusting the trigger features and connection chain in quasi-static bending / torsion, soft ball / pendulum impact and regulatory collision simulations or tests until the target is met.

[0012] Furthermore, the display module also includes: a security domain control unit, which has the final arbitration right for all external display control signals; an audit event collection unit, which is used to generate audit events when key actions such as external display-related requests, arbitration, token issuance / revocation, preemption / deactivation, template switching, etc. occur; a timestamp package generation unit, which is located in the trusted execution environment and packages the audit event with metadata containing at least policy package ID / version, threshold parameters, trigger reason, geographic location summary and time information into a timestamp package and completes the digital signature; a verifiable evidence storage unit, which triggers the timestamp package according to the period or threshold for dual-track Attestation: First, the digest / root hash is anchored to at least one of the following: blockchain, permissioned chain, or public chain anchor points; second, the full timestamp package is stored in local immutable secure storage. A proof and query unit provides verifiable proof and query interfaces to the vehicle, cloud, and regulatory entities. A display path execution unit is connected in series to the pixel / video critical path and is exclusively controlled by the security domain. Any external actions are only effective after the audit event record and timestamp package signature are completed. If signature verification fails, the anchor times out, or the local immutable storage is abnormal, the security domain preempts the controlled display template with the highest priority or disables it. The timestamp package records at least eight of the following: event ID, decision result (allow / deny / preempt), policy package ID / version, critical thresholds and their values, trigger reason code and actual measurement, display authorization token ID, display surface / partition ID, geofence ID, timestamp, and device / software metric summary. Time information is based on a hardware secure clock and cross-checked with GNSS / network time and a monotonic counter. Any inconsistency is marked as "time untrusted" and the strictest compliance and lock are enforced. Timestamp packets form a hash chain and Merkle trees are constructed in batches. The verifiable evidence storage unit periodically anchors the Merkle root to the chain, providing proof of membership and proof of freshness when queried. Local immutable secure storage utilizes a WORM / Secure Element (HSM / SE)-protected write path, forward-secure MAC, rollback counter, and atomic A / B partition switching. Failed writes automatically roll back, preserving the previous valid snapshot. Geographic and time fields are represented using gridded location IDs and time window labels. Fields involving personal data are hashed, desensitized, or redacted, allowing verifiers to obtain evidence through digests and proofs without accessing the original personal data. Signature private keys are stored in the HSM / SE and support key rotation. Anchored transactions and key events can utilize multi-signatures with a t / n threshold to enhance tamper resistance. Local immutable storage can be completed before the offline TTL, delaying on-chain anchoring. If the TTL expires or the cumulative anchoring failures exceed the threshold, the system enters a whitelist-only + controlled template mode until the anchoring is completed. The explicit path execution unit is released only when it receives an execution token containing the timestamp packet sequence number / digest; after execution, it must write back the completion event and generate a new timestamp packet to achieve strong binding and two-way reconciliation between actions and logs.Timestamp packets for multiple external display surfaces / partitions are anchored to the same Merkle root batch to ensure consistency across screens. Any anomaly on any surface will result in the entire batch being marked as "partially suspicious." A mandatory, separate anchoring policy is set and prioritized for events such as controlled template preemption, remote deactivation, key revocation, and policy revocation. The display path execution unit monitors pixel timing / bandwidth anomalies, topology changes, and unknown source access. When a bypass suspicion is triggered, a special event timestamp packet is generated and anchored first. On-chain anchoring supports at least one of permissioned, consortium, or public chain anchors. When a chain is unavailable, cross-organizational witness signatures are used as a temporary replacement. The attestation and query unit provides light client attestation, including proof of membership, proof of non-membership, temporal freshness, and anti-rollback proofs, enabling regulatory terminals to complete verification even with low bandwidth. Policy packages and threshold tables utilize monotonic version counts and anti-rollback metrics. Timestamp packets are signed with a version count and device metric summary, and version rollbacks trigger the strictest compliance. The timestamp packet contains a display authorization token ID and a watermark / audit ID digest, which can be used to align and verify off-board evidence with on-board logs across domains. The main body of the timestamp packet is stored locally encrypted with a partition key; only necessary fields are disclosed externally, or zero-knowledge / selective disclosure proofs are provided to reduce privacy exposure. Auditing and timestamp signatures are enabled by default at power-up; if the audit link self-test fails, the signature fails, or the anchor chain is unavailable, the system defaults to a controlled template / disabled. This mechanism is effective under any MIPI / eDP / LVDS / Ethernet video interface and any power supply mode: on-board high voltage / low voltage, external charging, portable power supply, or V2L. The verifiable evidence storage unit and timestamp packet generation unit can be integrated into the display controller / security domain controller or implemented as a retrofittable audit gateway. The method for displaying compliant, verifiable logs and timestamp packages externally on the vehicle includes: S1. Generating audit events and supplementing metadata such as policy version, threshold, trigger reason, geography, and time when relevant key actions occur; S2. Hash-chaining the audit events within a trusted environment, constructing a timestamp package, and completing the digital signature; S3. Writing the entire timestamp package to local immutable secure storage and anchoring the Merkle root or digest on-chain; S4. Issuing an execution token and driving the display path execution action only if the write / signature is successful; S5. Providing membership / freshness / anti-rollback proofs and lightweight queries externally; S6. Revoking the token and preempting it as a controlled template or deactivating it if any of the signing / anchoring / storage anomalies occurs. During offline periods, the system first writes to local immutable storage and accumulates batch roots; upon reconnection, the system supplements the anchors in chronological order and generates an on-chain confirmation record. Fields involving personal data are gridded, time-windowed, and hashed for desensitization; and selective disclosure or zero-knowledge proofs are provided externally on demand.The audit and timestamp gateway for vehicle external display system comprises: an event aggregation and timestamp package generation unit; a signature and anchoring unit: complete local signature, hash chain / Merkle root calculation and on-chain anchoring; an immutable secure storage unit: full volume evidence storage is realized by WORM / SE protection; a proof and query unit: output member / freshness proof and check playback evidence and watermark ID; a gate linkage unit: only when the audit is successful, the pixels / power supply are released, and the template is occupied in case of failure; the gateway provides independent and after-installable verifiable log and timestamp capability for external display without changing the rest of the vehicle functions. The gateway is in one of the forms of inline in the wire harness, connector tail end or independent box body, and interacts with at least one of the CAN / Ethernet in-vehicle bus. A computer readable storage medium has a program stored thereon, which causes the system to execute the method steps described above when executed by a processor.

The outer surface layer is selected from: chemically tempered glass, laminated glass, polycarbonate (PC), epoxy / acrylic transparent composite board, and is provided with an anti-shatter and anti-scattering coating and an anti-scratch / anti-glare microstructure. The display function stack is one of the following or a combination thereof: flexible OLED, Micro-LED micro-tile array, Mini-LED backlight liquid crystal, dot matrix LED, transparent conductive electrochromic or electrophoretic display; and its supporting substrate is a glass fiber / carbon fiber reinforced resin sheet, metal sheet or composite sandwich.

A functionally graded transition layer is provided between the display functional laminate and the structural backplane, with its equivalent elastic modulus and thermal expansion coefficient varying gradually along the thickness direction to inhibit interfacial delamination and crack propagation under load and thermal cycling. Controllable collapse units are pre-installed within the laminate, including crush beads, inverted thinning zones, trigger grooves, or micro-folding / corrugated zones. These are configured according to pedestrian protection requirements or along the collision load path to preferentially absorb energy and limit peak acceleration during impact. Toughening / crack-blocking components are arranged along the main load-bearing direction to form crack-stopping hole arrays, sandwich edge sealing tapes, Z-pins / stitched fibers, or nano-toughened interfaces. The periphery of the component is connected to the vehicle body frame through a hybrid connection of structural adhesive and mechanical connections. The mechanical connection includes undercut steps, perforated rivets, oblong hole sliding seats, and limit stops, making thermal expansion and dynamic deformation of the vehicle body controllable without causing interlayer tearing. The load path bypass mechanism is set between the display function stack and the structural backplane, including a shear yield plate or a buckling trigger beam. In the event of an over-limit impact, it automatically bypasses the main load from the display function stack to the structural backplane / body frame to avoid chain failure of the functional layer.The display stack utilizes replaceable micro-tile units, electrically and thermally coupled to a continuous structural backplane via elastic connectors and mechanically supported by the backplane, enabling local repairability without disrupting overall load-bearing continuity. Strain, acceleration, and temperature sensors are integrated within the component, along with a safety control circuit that triggers power outages, current limiting, and thermal isolation upon detection of abnormal impact or large deformation. Health monitoring data is also used for lifespan assessment. The component is formed into a three-dimensional curved surface, with its curvature achieved through pre-molding, autoclave curing, or 3D printing and co-curing. The display stack undergoes neutral layer position tuning during pre-molding to reduce bending strain. A transparent energy-absorbing interlayer, comprised of an ionomer, polyurethane, or silicone laminate, is placed between the outer surface layer and the display stack, providing both optical coupling and impact energy dissipation. The component edges feature a stepped-undercut composite interface and labyrinth seals to enhance perimeter resistance to peeling and water vapor intrusion. The structural backplate is locally integrated with the vehicle body frame via load-bearing flanges / reinforcement ribs / injected ribs, ensuring that the component's contribution to the vehicle's torsional and bending stiffness reaches a preset ratio. In pedestrian impact hotspots, the surface-to-core thickness ratio and trigger unit density are distributed by zone to achieve stiffness zoning and peak force control between soft and hard zones. The component surface is coated with a stone chip prevention / self-healing coating, maintaining impact toughness and transmittance at least within the preset temperature range of -20°C to 80°C. The heat dissipation / thermal expansion sheet of the display functional stack also serves as a load-bearing panel, forming a thermal-mechanical integrated path with the structural backplate through brazing, welding, or resin co-curing. Potential equalization and grounding between the component and the vehicle body are achieved via flexible equipotential bonding strips to ensure control circuit and electromagnetic compatibility in the event of a collision or high-current fault. The method also includes an integrated structural display assembly, including: S1) performing multi-field coupled simulation based on target vehicle body structural loads and regulatory scenarios (including pedestrian / low-speed / front / side impact) to determine the load path and energy absorption partitions; S2) selecting the material system and functional gradient transition layer parameters for the structural backplane-core-surface layer and the display functional stack; S3) preforming and neutral layer tuning the display functional stack, and co-curing or chemically bonding it with the structural backplane / core layer to form a non-delamination interface; S4) forming a stepped-undercut fit around the perimeter and injecting structural adhesive, while also providing mechanical limiters / sliding seats; S5) implanting a controllable crush unit and bypass mechanism at a specified location; and S6) performing structure-display joint calibration and health monitoring baseline collection.

The component communicates with the vehicle body controller to perform closed-loop management of health monitoring signals, and executes display degradation / power-off isolation / warning strategies in the event of a collision, stone strike, or excessive strain.

A neutral layer tuning sheet or pre-stretching configuration is provided between the display function layer and the structural load-bearing sublayer to ensure that the display function layer is located within the ± limit distance of the neutral plane in the thickness direction of the assembly. The structural load-bearing sublayer is a hybrid metal-composite structure: metal reinforcements / inserts are placed in high-stress paths, fiber composite panels are used over large areas, and co-curing / co-consolidation is used to form a continuous load-bearing path. The sandwich core material is configured with zoned density and thickness to match the bending stiffness and energy absorption requirements of different regions. Strain relief microstructures (micro-incisions, thinning strips, or micropore arrays) are placed along the isostress lines of the functional layer to prevent crack propagation and reduce in-plane strain.The electrical safety and energy management unit includes: one of solid-state relays / pyro-fuses / micro-initiation fuses in communication with the vehicle body restraint controller; a conductive shielding layer overlaid on the structural load-bearing sub-layer or the load-introducing bezel for EMI / EMC and touch electrical safety; automatically placing the display screen in a safe state or turning off when a collision is triggered.
