[0029] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] Currently, traditional theater large screen systems face the following technical bottlenecks:

[0031] 1. Fixed installation: The screen position cannot be adjusted, which cannot adapt to the dynamic changes in the stage scene, and the installation cycle and personnel costs are relatively large;

[0032] 2. Insufficient mobility: Existing mobile screens mostly rely on tracks or manual handling, which is not flexible and has low synchronization accuracy when multiple units are spliced ​​together;

[0033] 3. System separation: The display unit, support mechanism, power supply and control system are independent of each other, resulting in complex wiring and high failure rate;

[0034] Based on this, the present invention provides a movable and rapidly combinable theater screen display system, which can be applied to scenarios where images need to be displayed through a screen.

[0035] To facilitate understanding of this embodiment, a movable and rapidly combinable theater screen display system disclosed in this utility model embodiment will first be introduced, such as... Figure 1 As shown, the system includes: multiple AGV (Automated Guided Vehicle) trolleys, each AGV trolley 10 is fixedly connected to a mounting bracket 11, and the mounting bracket 11 is equipped with a unit screen 12 via a slide rail slot; the AGV trolley 10 is an intelligent equipment that can realize unmanned transportation; the aforementioned mounting bracket 11 is usually made of aluminum alloy truss structure (usually bending strength ≥300MPa), and is connected to the AGV trolley 10 by high-strength bolts (such as grade 8.8); rubber shock-absorbing pads (such as damping coefficient 0.3, etc.) are set between the mounting bracket 11 and the unit screen 12 to reduce the impact of mechanical vibration on the display screen 12. The back of the unit screen 12 is usually designed with a sliding rail slot, which can support the disassembly or installation of the unit screen 12 within 10 minutes, realizing the quick disassembly and assembly of the unit screen 12 and meeting the needs of emergency maintenance. The aforementioned unit screen 12 can be a four-screen or eight-screen spliced ​​in the vertical direction, etc., and the specific configuration can be set according to the actual application scenario, which is not limited here.

[0036] Multiple AGVs 10 operate in full-screen mode, group mode, or independent mode. In full-screen mode, multiple AGVs 10 are sequentially and horizontally spliced ​​and locked together so that the unit screens 12 mounted on each of the multiple AGVs 10 are combined into a large overall screen. In group mode, multiple AGVs 10 are divided into multiple groups, and all AGVs 10 within the same group are sequentially and horizontally spliced ​​and locked together so that the unit screens 12 mounted on each of the AGVs 10 within the group are combined into a large screen within the group. In independent mode, the unit screen 12 mounted on each AGV 10 displays its corresponding video screen.

[0037] In this embodiment, multiple AGVs 10 can operate in different working modes, namely full-screen mode, group mode, or independent mode. For example, in one embodiment, all AGVs 10 can be sequentially and horizontally spliced ​​and locked, i.e., operating in full-screen mode. This allows the unit screens 12 mounted on all AGVs 10 to be combined into a single large screen for displaying images. In another embodiment, all AGVs 10 can be divided into multiple groups, i.e., operating in group mode. The number of AGVs 10 in each group can be the same or different. All AGVs 10 in the same group are sequentially and horizontally spliced ​​and locked, allowing the unit screens 12 mounted on all AGVs 10 in that group to be combined into a single large screen for displaying images. For example, if all AGVs 10 are divided into two groups, the first large screen in the first group displays a sky image, and the second large screen in the second group displays a grassland image, etc. In another embodiment, each AGV trolley 10 can be controlled independently, and each displays the corresponding screen through the unit screen 12 it is mounted on.

[0038] The following are examples illustrating the relevant parameters of a single AGV vehicle and its attached unit screen:

[0039] (1) Load parameters of the screen body

[0040] 01. Total weight 1T: Display screen body (corresponding to the above-mentioned unit screen) 400kg; screen body bracket (corresponding to the above-mentioned mounting bracket) 300kg; control system, lithium battery and counterweight 300kg;

[0041] 02. Screen dimensions: 2m wide, 7m high, 10cm thick; mounted on a screen support frame; the screen support frame has the same width and height as the screen body, and the depth does not exceed 1.5m;

[0042] 03. The display screen and the AGV trolley share a power supply: the display screen has a power of 7.5 kW; and a single working time of 8 hours.

[0043] (2) Key parameters of a single AGV vehicle

[0044] 01. Stable movement and small footprint: Moves smoothly without tipping over;

[0045] 02. Overall footprint and projection dimensions: width 2m (same width as the screen), depth ≤ 1.5m;

[0046] 03. Movement speed: 0.5~1m / s;

[0047] 04. AGV trolley, screen, and battery are designed separately;

[0048] 05. The AGV trolley includes a suspension and stabilization mechanism;

[0049] (3) Parameters for multiple AGV cart combinations

[0050] 01. Combined use of 2-10 units: Multiple units can be precisely spliced ​​into a complete screen and then locked, and can be moved independently in groups, etc.

[0051] EG: For example, a group of 6 units (numbered ABCDEF)

[0052] Mode 1: Six units from A to F are linked together to form one screen, and the entire screen can be moved forward and backward and its orientation can be slightly adjusted left and right;

[0053] Mode 2: Groups of three units (ABC) and three units (DEF) move independently in four directions or move away from each other at the same speed.

[0054] Mode 3: Unlocked from Mode 1, 6 units move independently, and the 6 units form a 3+3 two-column tilted formation on the stage;

[0055] The aforementioned mobile and rapidly combinable theater screen display system can mount unit screens on mobile AGV carts, and can enable multiple AGV carts to work in full-screen mode, group mode, or independent mode according to the actual application scenario, thereby meeting the dynamic screen position change requirements and improving the stage performance effect.

[0056] Furthermore, each AGV includes multiple omnidirectional wheels.

[0057] Furthermore, each AGV includes: a retractable auxiliary support leg; the auxiliary support leg includes: multiple auxiliary support wheels.

[0058] The number of omnidirectional wheels and auxiliary support wheels can be 4, 6, etc., and can be set according to actual needs, without limitation here; the omnidirectional wheels can be Mecanum wheels, which can realize 360° omnidirectional movement and precise positioning of the AGV, for example, the movement accuracy can reach ±5mm, etc.

[0059] like Figure 2 The diagram shows an auxiliary support leg, which is located at the bottom of the AGV trolley and is a double-rail auxiliary support leg. Figure 3 The diagram shown illustrates the extended state of the auxiliary support leg. Figure 4The diagrams shown illustrate the retracted state of the auxiliary support legs. Figure 5(a) shows a side view of one type of auxiliary support leg, and Figure 5(b) shows a side view of another type. In the stationary state (where the screen is retracted), both the front and rear support legs are fully retracted, and the overall dimensions of the vehicle remain unchanged. In the moving state, the auxiliary support legs are fully extended, with the front support leg extending 430mm and the rear support leg extending 600mm. In the stationary state (where the screen is moved forward), the rear support leg remains fully extended, while the front support leg can retract to a suitable size to ensure it does not affect the lower side of the screen. Typically, the upper surface of the auxiliary support leg is 186mm above the ground, but this can be adjusted as needed.

[0060] Furthermore, each AGV is equipped with an airbag at the bottom;

[0061] Furthermore, the airbag is divided into multiple air chambers; each air chamber is equipped with its own corresponding pressure sensor.

[0062] In practice, an airbag can be installed at the bottom of the AGV vehicle. This airbag can be divided into multiple air chambers, and the number of air chambers can be set according to actual needs. A pressure sensor is installed at the corresponding position of each air chamber. During the movement of the AGV vehicle on the stage, the pressure on the corresponding air chamber can be detected by each pressure sensor.

[0063] When the AGV is not in motion, it can be fixed to the preset track by the guide rail roller limit and pulley limit mechanism to form a static support structure and reduce energy consumption.

[0064] In this embodiment, the screen controller of the unit screen can receive video signals via an HDMI 2.1 fiber optic cable (with a built-in anti-interference shielding layer), supporting a maximum resolution of 8K@60Hz; the video signal can be a video signal captured by a camera or a video signal transmitted over a network.

[0065] Regarding the power supply line, in this embodiment, the power supply line of the screen (AC220V) and the drive power supply of the AGV trolley (DC48V) are integrated into the waterproof cable tray inside the mounting bracket, and only standardized interfaces (such as aviation plugs) are retained on the outside, realizing "formal integration" and "functional separation".

[0066] Furthermore, the AGVs that are horizontally spliced ​​and locked are laterally limited by guide rail rollers and longitudinally limited by electromagnetic adsorption. Guide rail rollers, also known as linear guides, are mechanical components used to achieve linear motion. They typically consist of a series of rollers (or balls) and guide rails. The rollers roll on the guide rails, thus achieving smooth and precise linear motion. In practice, the laterally spliced ​​and locked AGVs can be connected using a dual method of "guide rail rollers + electromagnetic adsorption." The guide rail rollers provide lateral limitation, while the electromagnetic adsorption module (rated suction force ≥ 500N) provides longitudinal rigid locking, ensuring the overall structural stability (tensile strength ≥ 1000N / m) after multiple AGVs are spliced ​​together. For example, a single AGV has dimensions of 2000×1410×330mm (excluding mounting brackets), and the maximum screen size after multiple AGVs are horizontally spliced ​​can be expanded to 12m×1.41m×7.7m, covering an ultra-wide stage scene.

[0067] Figure 6(a) shows a connection diagram of multiple AGV vehicles, and Figure 6(b) shows another connection diagram of multiple AGV vehicles. Multiple AGV vehicles are connected horizontally in sequence so that the unit screens mounted on each AGV vehicle can be used in combination.

[0068] Figure 7(a) shows a schematic diagram of the body shape of one type of AGV, and Figure 7(b) shows a schematic diagram of the body shape of another type of AGV. The AGV includes four Mecanum wheels 70. The flat surface of the upper surface of the AGV can serve as a scaffolding installation platform 71. The AGV has an active connection mechanism 72 on one side and a passive connection mechanism 73 on the other side. The bottom of the AGV also has auxiliary support wheels 74. The key parameters of the body are as follows:

[0069] 01. Size:

[0070] Single AGV trolley: Length × Width × Height = 2000 × 1410 × 330 mm (excluding the height of the support on the trolley body, including the support is 1192 mm), the height of the display screen from the ground is 200 mm;

[0071] Multiple AGV carts: Length × Width × Height = 12000 × 1410 × 7700 mm;

[0072] 02. Wheel system: Four Mecanum wheels + four support wheels

[0073] 03. Connection method: guide rail roller limit + pulley limit

[0074] Figure 8(a) shows a schematic diagram of a multi-vehicle connection mechanism. The active connection mechanism of one AGV can be connected to the passive connection mechanism of another AGV. Figure 8(b) shows another schematic diagram of a multi-vehicle connection mechanism, and Figure 8(c) shows another schematic diagram of a multi-vehicle connection mechanism. After connection, the connection part shown in Figure 8(b) can be used as a screen body forward limiting mechanism, and the connection part shown in Figure 8(c) can be used as a vehicle body connection limiting mechanism.

[0075] Furthermore, each AGV has its own built-in lithium battery; multiple AGVs are interconnected through a preset interface to share power. This preset interface can be a high-voltage quick-connect interface with an IP67 protection rating. In this embodiment, the power supply mode can be either an independent power supply mode or a shared power supply mode. In the independent power supply mode, each AGV can have a built-in 48V / 20Ah lithium battery, and each lithium battery can independently power its corresponding unit panel (7.5kW) and vehicle motor (2kW). In the shared power supply mode, multiple AGVs are interconnected through a high-voltage quick-connect interface (IP67 protection rating), supporting centralized power distribution, similar to the "distributed power + centralized dispatch" mode of high-speed trains. In addition to independent power supply, each AGV can be connected through the preset interface, allowing other AGVs to be dispatched to share power with one or more AGVs.

[0076] Specifically, each AGV can be equipped with a lithium iron phosphate battery pack (5kWh, cycle life ≥2000 times), which switches between the main power supply (such as AC power) and the main power supply via a solid-state relay (SSR), with a switching time ≤10ms.

[0077] In the shared power supply mode, multiple AGV workshops can deploy a ring power supply bus, and the battery of any AGV can provide emergency power to the core screen of other AGVs.

[0078] Furthermore, each AGV has a speaker mounted on its mounting bracket;

[0079] In this embodiment, a speaker slot can be pre-installed on the rear side of the mounting bracket of each AGV trolley. The size of the speaker slot can be set according to actual needs, such as 600×200×150mm. The speaker slot typically has a built-in shock-absorbing bracket and heat dissipation duct. The speaker can be fixed using a combination of quick-release clips (tensile strength ≥200N) and magnetic attraction. This fixing method allows for speaker installation and removal within 5 seconds. For example, on a theatrical performance stage, to ensure the performance effect, multiple speakers can be set up, with at least one speaker playing the actors' voices.

[0080] The system has been improved in the following aspects:

[0081] Multi-degree-of-freedom AGV grouping: Supports any combination of 2-10 AGVs, and achieves a rigid-flexible connection through "mechanical locking + electromagnetic adsorption", which ensures splicing accuracy (error ≤2mm) and allows small relative displacement (±5mm) to absorb stage vibration.

[0082] The unique "3+3 tilt formation mode" creates a dynamic stage visual effect through the independent steering mechanism of the AGV (steering angle ±45°).

[0083] 2. Integrated cable concealment design:

[0084] All power and signal cables are embedded in the aluminum alloy profile inside the bracket (IP54 protection rating), with only waterproof interfaces remaining on the outside; flexible PCB boards are used to replace some cables, reducing the number of connectors and improving reliability.

[0085] 3. Modular AGV support system, supporting multiple units to be freely combined and independently controlled;

[0086] 4. Highly integrated design of display, power supply, control, and audio functions;

[0087] This system can bring the following beneficial effects:

[0088] 1. Enhanced stage effects: Supports multi-mode screen transformation, enhancing visual impact;

[0089] 2. Optimized operation and maintenance costs: Modular structure improves maintenance efficiency by 50%, and cable integration reduces consumable consumption;

[0090] This system specifically relates to a mobile large-screen display system based on modular AGVs (Automated Guided Vehicles), integrating ultra-high-definition LED display, multi-mode grouping control, integrated power supply, and emergency backup functions. It is suitable for dynamic display needs in theaters, studios, exhibition halls, and other similar settings. Through the mobility and modular assembly capabilities of the AGVs, the system enables rapid layout and reconstruction of the large screen, significantly improving the flexibility and safety of stage effects.

[0091] This solution combines unit screens and AGV carts, offering robustness and support for various steering wheels. The unit screens can be moved with the AGV carts, from off-site to on-site, meeting emergency needs. They are also easy to disassemble, facilitating performances in other scenarios. Furthermore, they can be moved to designated locations on-site, such as figure-eight screens, used as auxiliary screens, or combined with multiple secondary screens.

[0092] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
