[0008] The data transmission module supports low-delay and high-bandwidth video stream transmission based on a self-defined transmission protocol, and has a seamless switching function in multiple communication modes. The communication modes include but are not limited to LVDS, HDBaseT Automotive, a special video transmission bus and an optical fiber transmission path.

[0009] The anti-vibration module is arranged between the dynamic display module and the vehicle body, used for reducing mechanical impact of the dynamic display module caused by road bumps or vehicle vibration during vehicle driving, and reducing vibration conduction between the dynamic display modules; the anti-vibration module includes a multi-stage buffer structure, at least including an elastic support layer and a damping material layer. A multi-point support structure is adopted to allow local micro-displacement, used for avoiding screen stress concentration caused by sudden acceleration and deceleration, sharp turning, bumpy road, vehicle body torsional deformation, single wheel impact and strong wind and rain and hail and the like. Optionally, the dynamic display modules are connected to each other through a distributed anti-vibration connecting piece, the connecting piece including an elastic connecting arm with a relative displacement limiting function, used for further reducing relative shaking between the dynamic display modules. Optionally, the anti-vibration module further includes an electronic vibration detection device and an active vibration reduction control unit, the electronic vibration detection device used for detecting a vibration signal, and the active vibration reduction control unit used for adjusting the state of the anti-vibration module according to the detection signal.

[0014] Optionally, the dynamic display module includes but is not limited to: flexible display screens, LED display screens, OLED display screens, transparent display screens, industrial-grade display screens, curved display screens, display films, electronic ink screens, folding screens, holographic projection screens or touch screens.

[0015] Optionally, an anti-vibration module is arranged between the display screen module and the vehicle body, and is used to reduce the mechanical impact of road bumps or vehicle vibrations on the display screen module during vehicle driving, and reduce the vibration transmission between multiple display screen modules; the solar energy collection and conversion module includes a solar cell panel, a voltage stabilizing device and an electric energy output interface, and is used to convert the received solar energy into electrical energy and power the display screen module; wherein, the anti-vibration module includes a multi-stage buffer structure, which includes at least an elastic support layer and a damping material layer. The solar energy collection and conversion module is integrated into the edge or surface of the display screen module and is switchably connected to the vehicle power system.

This isolation structure significantly minimizes the impact of bumpy roads and vibration from adjacent display screens. Multiple display modules are interconnected via distributed anti-vibration connectors, which include elastic connecting arms with relative displacement limiting functions to further reduce relative motion between the display screens.

[0017] Optional: Seismic module with the following features:

[0018] Displacement tolerance threshold: The local micro-displacement range is limited to 1-8mm, and the displacement recovery time is ≤50ms. Reason: <1mm cannot effectively release stress, and >8mm will cause visible screen deformation; when the recovery time is >50ms, continuous bumps will cause accumulated displacement, resulting in screen misalignment.

[0019] Dynamic range of damping force: The damping force adjustment range of the magnetorheological damping support is 100-5000N·s / m, and the response time is ≤10ms. Reason: Below 100N·s / m, it cannot withstand single-wheel impact (the measured impact force on gravel roads is ≥300N); above 5000N·s / m leads to excessive structural rigidity and loss of shock absorption function; a response delay of >10ms cannot cope with sharp turns (the centrifugal force mutation period is 15-20ms).

[0020] Lower limit of support point density: At least 8 independent support points are set per square meter of display area, and the distance between adjacent support points is ≤150mm. Reason: <8 points / m 2 When the finite element simulation shows that the stress concentration of the corners is greater than 120MPa (exceeding the yield limit of the screen); the spacing of greater than 150mm leads to a 20cm 2 There is no support in the area, and the risk of rupture during hail impact increases by 83%.

[0021] Curvature adaptation accuracy: The curvature matching error between the display module and the body panel is ≤0.5° / m. Reason: An error of >0.5° / m results in a gap between the screen and the body of >3mm, an increase of 12dB in high-speed wind noise, and easy water accumulation.

[0022] Environmental tolerance threshold: within the temperature range of -40℃ to 85℃, the brightness decay rate of the display module is ≤15% "Reason: Beyond this temperature range, conventional OLED / LED appears dead light; >15% brightness decay makes the visibility under strong light substandard (ISO vehicle display standard requires ≥1000 nit).

[0023] Vibration compensation real-time performance: the control system completes the screen displacement compensation instruction output within 5ms according to the vehicle body acceleration sensor data "Reason: >5ms delay will cause compensation to lag behind the vehicle body distortion frequency (the main frequency of the main road distortion is 20-50Hz).

[0024] Stress dispersion effectiveness: the anti-shock module makes the screen stress concentration coefficient ≤1.8 (compared to the baseline value ≥4.2 without anti-shock module) "Reason: >1.8 stress coefficient will cause micro-cracks to expand rapidly (referring to JESD22-B111 mechanical impact test standard).

[0026] a) Damping force dynamic adjustment range 100-5000N·s / m

[0028] c) Under 20Hz sinusoidal vibration input, the screen amplitude decay rate is ≥90%

[0029] d) Local micro-displacement 1-8mm, and displacement recovery time ≤50ms

[0030] Reason:

[0031] Displacement 1-8mm | Test basis: real vehicle road spectrum collection (Belgian road / speed bump) | <1mm, stress release is insufficient, >8mm, mechanical design needs to be reconstructed

[0032] Damping response ≤10ms | Test basis: bench step response test | When the competitor uses ordinary hydraulic damping, the response is >30ms

[0033] Curvature error ≤0.5° / m | Test basis: laser three-dimensional scanning comparison | Traditional lamination process error >2° / m

[0034] Temperature range -40~85℃ | Test basis: thermal shock test (IEC 60068-2-14) | The working temperature range of commercial display screens is usually -20~70℃
