Description

Technical Field

[0001] This invention relates to the field of XR (including VR, AR, MR), 3D image interaction, and immersive somatosensory leisure equipment technology. Specifically, it is a multimodal immersive interactive somatosensory simulation seat system that integrates multi-sensory feedback and multi-scene adaptation. It is suitable for e-sports entertainment scenarios such as XR movies, large-scale AAA games, small casual games, and racing simulators, as well as sleep-aiding leisure scenarios such as space floating and sea floating. Through the coordinated control of vibration, wind, 3D sound effects, and posture adjustment, it combines immersive interactive experience with leisure and sleep-aiding functions, while also having a safety guarantee mechanism of mechanical locking and human body detection. Background Technology

[0002] With the rapid development of XR (including VR, AR, MR), 3D imaging technology, gaming entertainment, and the leisure and health industry, user demand for motion-sensing interaction devices is gradually upgrading towards "multi-scene adaptation," "multi-sensory immersion," and "safety and convenience." Motion-sensing chairs, as a core interactive carrier, have been widely used in e-sports entertainment, movie viewing, and relaxation / sleep aid scenarios, but existing technologies still have the following significant shortcomings: 1. Insufficient coordination of multi-sensory feedback: Most existing motion-sensing seats only integrate a single vibration function or an independent sound effect module, lacking coordinated control of vibration, wind, and 3D sound effects. For example, in a game, an "explosion" scene only triggers local vibration without corresponding airflow impact and surround sound effects, resulting in limited immersion. Meanwhile, simple motion-sensing seats adapted for small leisure scenarios lack sufficient vibration intensity and sound effect layering, failing to meet the feedback needs of different interactive scenarios.

[0003] 2. Limited Scenario Adaptation and Fragmented Functions: Existing products mostly focus on single usage scenarios. Gaming chairs emphasize strong stimulating feedback, while sleep aid chairs only focus on posture adjustment or white noise playback. The two lack integrated design. If users need to combine gaming entertainment with relaxation and sleep aid, they need to purchase multiple devices, which takes up space and has high operating costs. At the same time, existing chairs have not been adapted to different feedback logics for different scenarios such as XR movies, large-scale 3A games, small casual games, and racing simulations, resulting in insufficient versatility.

[0004] 3. Inadequate safety protection mechanisms: Some seats with mechanical adjustment or vibration functions lack effective human body detection and emergency locking designs. For example, they may continue to move when a child is close, posing a collision risk. Moreover, the mechanical locking structure and the somatosensory feedback function are often independent of each other, and the lock may loosen during vibration, affecting the safety and stability of use.

[0005] 4. Poor linkage between posture adjustment and sensory feedback: Existing chairs with posture adjustment functions mostly rely on manual control or fixed programs for angle adjustment (such as zero-gravity posture or floating simulation posture), without synchronous linkage with sensory feedback such as vibration, wind, and sound effects. For example, when simulating "space floating", only the seat angle is adjusted, without corresponding low-frequency vibration and environmental sound effects, resulting in poor immersion and relaxation effects for leisure and sleep.

[0006] 5. Insufficient ease of installation, fixation, and relocation: Existing VR gaming chairs mostly rely on expansion screws and other fixing methods, which are cumbersome to install and easily damage the ground. At the same time, they lack flexible relocation capabilities, making it difficult to adapt to the layout requirements of different usage spaces, and unable to cope with the stability requirements of different ground environments such as smooth or non-smooth surfaces.

[0007] Therefore, there is an urgent need for a motion-sensory simulation seat system that integrates multi-sensory collaborative feedback, accurately adapts to multiple scenarios, has comprehensive safety protection, is easy to install and fix, and can be flexibly moved. This system would solve the problems of functional fragmentation, insufficient immersion, lack of safety, and inconvenience in installation and relocation in existing technologies, and meet the user's needs in various scenarios such as e-sports entertainment and leisure sleep aid. Summary of the Invention

[0008] I. Purpose of the Invention This invention aims to overcome the shortcomings of existing motion-sensing seats, such as limited adaptability to multiple scenarios, insufficient dynamic adjustment dimensions, weak multi-sensory feedback coordination, and inadequate safety protection. It provides a multimodal immersive interactive motion-sensing simulation seat system that integrates five core dynamic modules, multi-sensory collaborative feedback, precise adaptation to all scenarios, and comprehensive safety protection. It enables seamless switching between e-sports entertainment scenarios such as XR (including VR, AR, MR) movies, large-scale AAA games, small casual games, and racing simulators, and sleep-aiding leisure scenarios such as space floating and sea floating. Simultaneously, it caters to both daily office and sleep needs. Through deep collaboration between mechanical structure and electronic systems, it solves the problems of fragmented functions, cumbersome operation, poor adaptability, and safety hazards in existing products, thereby improving the user's immersive interactive experience and usage safety. Technical solution

[0009] This invention constructs a multi-dimensional, highly collaborative, and highly secure haptic interaction system through an integrated design that includes "seat body + five core dynamic modules + new functional modules + multi-sensory feedback system + safety protection system + APP intelligent control terminal + extended accessory adaptation module". The specific technical solution is as follows: (I) Overall structural composition 1. Seat Body: Serving as the foundation for all functional modules, it adopts an ergonomic design and includes the base, backrest, and seat cushion (e.g., ...). Figure 1The base is made of high-strength material and has reserved space for the installation of electronic components such as the main control board and amplifier board. It features 4-8 (preferably 4) retractable support structures (available in home and demonstration versions: home version retractable length 1-1.5m, standby length 0.6-1m; demonstration version retractable length 2-3m, standby length 1.5-2m). The bottom of the support feet adopts a detachable modular design and can be equipped with a vacuum adsorption air cushion module (such as...). Figure 1 (19) Alternatively, a large-area contact anti-slip disc base can be used; the base can be stabilized in different ground conditions by manually adjusting the adsorption strength. In standby mode, the seat cushion is 40-60cm above the ground, adjustable via an app. The backrest and seat cushion feature an ergonomic support structure, with pre-installed mounting points for motors, speakers, fans, and seatbelt anchors. The backrest integrates audio components (such as...). Figure 1 11), seat cushion (such as Figure 1 14) Spacing is reserved at the bottom for circuit board installation (e.g.) Figure 2 (15), and integrates a subwoofer (such as Figure 2 Components such as the drive motor (e.g., 13) Figure 2 2) The handrail has a reserved position to accommodate an emergency stop button (such as...). Figure 1 Components such as 17) are installed; the front end has a manual telescopic foot pedal mounting position and a storage cavity for the telescopic extension component, and the bottom has a reserved expansion installation interface (such as...). Figure 1 (15) After the extension component is extended, it forms a complete support surface with the seat body, realizing a fully reclining state and adapting to sleep needs.

[0010] 2. Five Core Dynamic Modules (Core Drive System): These modules enable multi-dimensional attitude adjustment, covering core dynamic requirements such as rotation, swaying, and lifting. Each module can utilize power components such as trapezoidal lead screw motors and geared motors, coupled with transmission mechanisms such as bearings and gears. All modules are equipped with a dual locking mechanism (lead screw self-locking + mechanical pawl locking; the lead screw self-locking provides automatic locking under normal conditions, while the mechanical pawl, installed at the drive motor output, immediately engages the transmission structure in case of power failure or emergency stop, providing dual-coordinated anti-displacement protection) to ensure safety. All dynamic modules are uniformly adapted to a load-bearing standard: standard load ≤ 120kg, extreme load ≤ 150kg. All action commands for the dynamic modules are controlled by the main control unit (e.g., ...). Figure 2 15) Centralized and synchronous distribution: - Dynamic Module 1 (Bottom Rotation): Composed of vertical rotating load-bearing columns (such as...) Figure 1 1) It consists of a built-in rotary motor and transmission mechanism, which is connected by a rotating shaft (such as...) Figure 2 (18) Drive the seat to rotate 360° clockwise or counterclockwise, with a self-locking function to prevent self-rotation when power is off; - Dynamic Module Two (Seat Rocking): Composed of transverse load-bearing columns and load-bearing shafts (such as...) Figure 2 (1, 17) with a swing motor (such as Figure 2 (16) Collaborative drive to achieve seat rocking motion; the module's maximum rocking angle is 90°, limited to 60° in normal mode, and can be unlocked to 90° in sleep aid mode, simultaneously linking with the seat cushion base motor (such as... Figure 2 2) Reverse rotation, working in conjunction with the seat cushion to form a flat surface; - Dynamic Module Three (Lifting Adjustment): Based on the vertical main load-bearing shaft (e.g., Figure 2 4, 5), rising steel columns (such as...) Figure 2 6) Shock-absorbing springs (such as...) Figure 2 7) and lifting motor (such as Figure 2 The middle part consists of 3), with a lifting motor driving the seat to extend and retract vertically (extension range 20-50cm). The maximum travel can adapt to the interactive feedback needs of different scenarios. The drive structure adopts a trapezoidal screw motor, which has the function of automatically fixing after stopping. - Dynamic Module Four (Backrest Rotation): Integrated rotating axis (e.g.) Figure 3 5) Rotary drive motor (such as Figure 2 (8) and left and right swaying fixing components (such as Figure 3 (4, 10), enabling the seat to rotate 360° (normally limited to 120 degrees left and right, unlockable in special demonstration scenarios) and rock left and right in dual dynamic states, via a central load-bearing column (such as... Figure 2 The reinforced structure (e.g., 10) ensures load-bearing capacity and stability. - Dynamic Module 5 (Backrest Backrest Rocking): Powered by a trapezoidal lead screw motor (such as...) Figure 3 1) Gear assemblies (such as...) Figure 3 2) and the front of the cushion supports the pillar (such as Figure 2 12) Collaborative drive to achieve backrest fixed axis (such as Figure 3 3) Back-and-forth swaying motion; the maximum swaying angle of this module is 90°, and it is limited to 50° under normal conditions. The transmission is smooth and powerful, and there is no lateral force to cancel it out.

[0011] 3. New functional modules: - Foot pedals: i.e., retractable foot pedals (such as...) Figure 1 (16) Connects to the seat cushion, can rotate 90° and is equipped with a Velcro fastening structure; - Detachable expansion interface: via the expansion mounting interface at the bottom of the seat body (such as...) Figure 1 (15) Assembly, in which the foot support extension accessory can be controlled to extend and retract via a power component to meet the foot support requirements when the seat is in a flat position; this extension installation interface also supports the assembly of external interactive devices such as racing steering wheels, adapting to the needs of multiple usage scenarios; - Moving component: Consists of a main body with retractable base support legs (such as...) Figure 15) Basic support casters (such as...) Figure 1 (6) and pulley-operated discharge machines (such as...) Figure 1 The device consists of three parts: (3) When the device is off, the support legs retract upwards to allow the pulleys to touch the ground and move flexibly; when the device is on, the support legs extend downwards to touch the ground and fix the device securely, thus completing a quick switch between 'moving-fixed' modes.

[0012] 4. Multi-sensory feedback system: Constructs a triple immersive experience of "touch + hearing + air sensation," with each component available in standard compatible models. - Vibration module: Includes vibration sensor (e.g.) Figure 2 11) Vibration motor (such as Figure 2 (14) Multiple graded vibration motors support 0-100% speed adjustment, adapting to different vibration needs in different scenarios; - Airflow module: i.e., air outlet (fan assembly, such as...) Figure 1 (12) Multiple miniature silent fans can be installed in areas such as handrails, with individual speed settings, and synchronized with vibration and sound effects; - Audio module: consists of 4 small speakers (such as...) Figure 1 (11, 13) + subwoofer (e.g.) Figure 2 (13) Form a multi-channel system, installed in different areas, supporting independent channel adjustment and scene-based sound effect linkage; -XR and game interaction integration: Motherboard mounting position (e.g.) Figure 2 15) Deploy feedback compilation components for XR devices, games, or interactive software, and integrate optional standardized interfaces (such as Type-C, HDMI, DP, RJ45, or dedicated data interfaces). It also supports wired or wireless connection modes. The main control unit can connect with external computers, XR (including VR, AR, MR) devices, game consoles, etc. in real time through the above-mentioned reserved interfaces (wired) or wireless communication modules (such as Wi-Fi, Bluetooth, etc.). The interface type and connection mode can be flexibly selected according to the usage scenario. It receives scene trigger signals and synchronously drives the linkage of various systems.

[0013] 5. Safety protection system (independently designed): - Emergency stop button (e.g.) Figure 1 17): It can be embedded in convenient operating areas such as armrests, connected in series with the main power circuit, and cuts off the power supply and slowly returns to standby state after being pressed; - Seat belt system: The waist and shoulder belts are three-point forced seat belts with built-in trigger switches in the buckles, which cannot be activated if not fastened; the foot belts can be Velcro seat belts, which restrict the corresponding functions when not worn. - Interlock activation conditions: The main control unit will only execute the mode command if the following conditions are met simultaneously: "seat belt fastened, foot extension bar deployed, no emergency stop triggered, and no abnormality detected by radar". - Security detection radar (such as Figure 1 (18): Detection range 2-8㎡, real-time monitoring of the surrounding environment, if any interfering object enters, it will force an emergency shutdown, and trigger a safety linkage in case of abnormality.

[0014] 6. APP Smart Control Terminal: Utilizes wireless communication, with an interface including function modules for mode switching, parameter adjustment, security settings, and extended control. - Mode switching: One-click triggering of zero-gravity sleep aid, XR and e-sports interaction, daily office, sleep and other modes; - Mode refinement: XR and e-sports modes support multiple levels of adjustment (corresponding to different dynamic amplitudes), and the sleep aid mode supports multiple experience types such as space floating, sea floating, and random floating, which can be upgraded and expanded in the future; - Parameter adjustment: Vibration intensity, fan speed, sound volume, sleep aid buoyancy intensity and other parameters can be adjusted by sliding. The seat shape can be adjusted independently in static mode. - Safety settings: Displays seatbelt status, radar detection status, etc., and supports radar distance sensitivity adjustment; 7. Extended accessory adapter module: via extended installation interface (such as...) Figure 1 (15) It can be flexibly equipped with extended foot pads, racing steering wheels and other controllers, supports game direction control and dynamic linkage with the seat, and is compatible with XR movies, racing, flight, space battle and other simulator scenarios.

[0015] (II) Core Linkage Logic 1. Safety linkage logic: When the radar detects an anomaly, the emergency stop button is pressed, or the seat belt is not fastened, the main control unit quickly cuts off the power output and controls the seat to reset; when critical components are not deployed, only the basic function mode is supported. 2. Component collaboration logic: All systems are centrally linked through the main control unit, with low instruction transmission latency, ensuring the real-time performance of XR and game interactions.

[0016] Beneficial effects;

[0017] 1. Strong adaptability to multiple scenarios: Five core dynamic modules plus newly added functional modules cover all-dimensional needs such as rotation, rocking, height adjustment, and reclining. Seamlessly switch between XR movie, e-sports, sleep aid, office, and sleep scenarios. The home version can be used as a regular e-sports chair when retracted, without the need to purchase additional equipment, saving space and costs. 2. Prominent Immersive Experience: The multi-sensory feedback system is deeply integrated with XR and game scenes, and with expandable accessories, it creates a four-fold immersive experience of "touch + hearing + air sensation + operation", far exceeding the single-function haptic chair. 3. Comprehensive safety protection loop: Emergency stop button, mandatory seat belt, multiple start interlocks, and safety detection radar form multiple safety protections. The mechanical + electronic dual locking or power-off design completely avoids the risks of collisions, accidental start, etc., making it more reliable to use. 4. Intelligent and convenient operation with high personalization adaptability: The APP supports one-click switching of all modes and stepless adjustment of parameters, which can adapt to different user body types and usage habits. More XR and interactive experience functions can be expanded through software upgrades in the future. 5. Reasonable structural design and high feasibility for mass production: each component can be selected from mature and compatible models, the installation method conforms to conventional processing technology, and expansion accessories support flexible installation, which is convenient for large-scale production and promotion; 6. Strong functional expandability: It reserves space for electronic component installation, expansion interfaces and software upgrades, and can continuously upgrade XR adaptation capabilities, experience modes and functions based on the existing framework to enhance long-term use value; 7. Flexible installation without ground damage: The retractable support structure of the chassis, combined with the vacuum adsorption air cushion module, eliminates the need for expansion bolts, thus avoiding damage to the ground; it also supports switching between mobile and fixed modes, freeing it from the installation constraints of traditional large equipment and adapting to more usage scenarios.

[0022] The following is a brief description of specific embodiments of the present invention with reference to the accompanying drawings. These embodiments are preferred examples and are not limited to the scope of protection of the present invention. Equivalent substitutions or improvements based on the technical concept of the present invention are all included in the scope of protection.

[0023] I. Basic Structure of the Seat Body 1. Core load-bearing structure and materials: The main load-bearing frame of the seat (including the metal support frame of the base, backrest, seat cushion, and armrests, vertical and horizontal load-bearing columns, support legs, telescopic support rods, and key load-bearing components such as the front support pillar of the backrest) can be made of ultra-hard and high-strength metal materials such as high-strength alloy steel and high-quality carbon structural steel. Some core connections are reinforced by welding. The outside of the frame is filled with flexible cushioning material. The normal load-bearing capacity is ≤120kg, and the ultimate load-bearing capacity is ≤150kg. 2. Functional provisions and auxiliary components: The handrail is integrally molded and incorporates an emergency stop button (e.g., Figure 1 17) and air outlet (such as Figure 1 12); Equipped with telescopic foot pedals (e.g.) Figure 1 (16) Features Velcro fastening; seat cushion (e.g.) Figure 1 14) Reserved space for circuit board installation and expansion installation interfaces at the bottom (such as...) Figure 1 (15) and the retractable extension component storage cavity, which can be extended to form a fully reclining position; at the same time, a seat belt fixing structure is reserved; 3. Telescopic support assembly: The base is evenly distributed with 4-8 (preferably 4) telescopic support rods (such as... Figure 1 (2) Based on usage scenarios, it is divided into a home version and a demonstration version: the home version has a telescopic length of 1-1.5m and a standby length of 0.6-1m; the demonstration version has a telescopic length of 2-3m and a standby length of 1.5-2m; its drive structure consists of a telescopic rod motor (such as...) Figure 1 In section 7, an anti-pinch servo motor is used, along with a telescopic rod gear (such as...). Figure 1 Composed of components (8), the telescopic rod's extension and retraction stroke is precisely controlled via a motor-driven gear meshing transmission. This anti-pinch servo motor has a load sensing function; if it encounters an obstacle (such as a person or debris) during extension, it will detect resistance through current changes, automatically stop operation, and slightly reverse its movement to avoid crushing injuries and ensure safe use. The support feet feature a detachable modular design: smooth surfaces (such as tiles or wooden floors) can be fitted with a vacuum adsorption air cushion module (such as...). Figure 1 (19) The air cushion module can be quickly removed and replaced with a large-area contact anti-slip disc base (compatible with support foot installation interface) on non-smooth surfaces (such as carpets and cement floors). By increasing the contact area, the friction is improved, ensuring the support stability in different ground environments and adapting to the needs of home use, demonstrations and other scenarios.

[0024] 4. Retractable and extendable foundation support frame assembly, including the foundation support frame body (e.g., Figure 1 5) Basic support casters (such as...) Figure 1 (6), by pulley-driven discharge machine (such as...) Figure 1 3) As a power unit, the motor only drives the support leg to achieve the up and down retraction action (no rotation function): when the motor is off, the motor drives the support leg to retract upward (the pulley lands on the ground) and make contact with the ground to achieve flexible movement; when the motor is on, the motor drives the support leg to extend downward (the pulley leaves the ground) and make contact with the ground to achieve stable fixation, thus completing the quick switching between the "fixed-moving" mode.

[0025] 5. The seat integrates three dynamic modules: rotation, rocking, and lifting. It supports independent operation of a single module or synchronous linkage of multiple modules. It can output composite dynamic effects according to XR / game scene signals to achieve an immersive interactive experience.

[0026] II. Installation and Debugging of Core Dynamic Modules (a) Seat Rotation Module - Core component: Vertical rotating load-bearing column (such as...) Figure 1 1) Built-in adjustable speed servo motor (suitable for narrow installation spaces), gear transmission mechanism, rotary shaft (such as...) Figure 2 18) and mechanical pawl locking assembly.

[0027] - Installation points: 1. The vertical rotating load-bearing column is fixed vertically to the center of the base, with no false welds at the weld point to the base, and the verticality error is ≤0.5°. It can bear a maximum weight of 150kg by relying on the structure of the load-bearing column itself. The motor is only responsible for providing rotational driving force and does not need to bear the load. 2. The output of the adjustable speed servo motor meshes with the rotating shaft through a gear transmission mechanism, with a transmission ratio optimized to 1:2. The motor speed can be steplessly adjusted in real time according to the computer signal (to meet the dynamic response requirements of game scenarios), combining fast start-stop sensitivity with sufficient driving force. The gear set is coated with wear-resistant grease to reduce operating noise. 3. The mechanical pawl locking device is installed on the side of the motor output end, precisely meshing with the tooth groove of the rotating shaft. It locks immediately in the event of power failure or emergency stop, eliminating the risk of displacement and meeting safety protection requirements.

[0028] - Operating Logic: After receiving the scene trigger signal, the main control unit sends a rotation command to the built-in motor, which drives the rotating shaft through the transmission mechanism to rotate the seat 360° clockwise / counterclockwise. The speed can be adaptively adjusted according to the scene requirements (such as fast turning in e-sports scenes and slow rotation in sleep-aid scenes). When linked with other dynamic modules, the main control unit synchronously controls the timing to avoid motion interference.

[0029] (ii) Seat rocking module - Core components: lateral load-bearing columns and load-bearing shafts (such as...) Figure 2 1, 17), swing motor (such as Figure 2 16) Transmission gear set, angle limit sensor and double locking mechanism.

[0030] - Installation Notes: 1. The horizontal load-bearing column runs horizontally through both sides of the seat base and connects with the vertical load-bearing column (used to support the rotation function); a reinforced end plate (commonly known as a "flange") is added at the connection point and fastened with high-strength bolts. The bolt tightening torque must reach 40 N·m to ensure that the connection structure is stable and impact-resistant, and can meet the rotation and swaying requirements under an extreme load of 150 kg. 2. The swing motor is fixed to one end of the horizontal load-bearing column. The motor output shaft meshes with the load-bearing shaft through a gear set. The gear meshing clearance needs to be controlled within 0.1-0.3mm to ensure smooth transmission. 3. Angle limit sensors are installed at 60° (normal mode limit) and 90° (sleep aid mode limit) of the swing stroke, respectively, and are connected to the main control unit to achieve precise angle control; 4. Use the built-in screw self-locking function of the trapezoidal screw motor to lock in conjunction with the motor: when the motor stops rotating in the non-running state, the screw automatically locks the current swing angle to prevent the seat from moving unexpectedly.

[0031] - Operating Logic: In normal mode, the swing angle is limited to 60° by the limit sensor, adapting to the mild swing needs of scenarios such as e-sports and office work; in sleep-aid mode, the main control unit unlocks the limit threshold, allowing the swing angle to reach 90°, and simultaneously activates the trapezoidal screw motor of the seat base (e.g., Figure 2 2) Reverse rotation allows the seat cushion and backrest to work together to form a flat lying surface, which, combined with the soothing mode of the multi-sensory feedback system, enhances the relaxation effect.

[0032] (III) Backrest rotation and back-and-forth rocking module - Core components: 1. Backrest swivel assembly: swivel shaft (e.g.) Figure 3 5) Rotary drive motor (such as Figure 2 8) Left and right swaying fixing components (such as...) Figure 3 4, 10), intermediate load-bearing columns (such as...) Figure 2 10); 2. Backrest rocking assembly: Trapezoidal screw motor (e.g., Figure 3 1) Gear assemblies (such as...) Figure 3 2) The front of the cushion supports the pillar (such as...) Figure 2 12) Backrest fixing shaft (such as Figure 3 3).

[0033] - Installation Notes: 1. Backrest swivel assembly installation: Backrest swivel shaft (e.g.) Figure 3 5) Installed laterally in the upper area of ​​the backrest, a trapezoidal lead screw motor serves as the core of the rotary drive (rated torque ≥50 N·m), and its output end is connected to the rotary shaft via a gear assembly; matching fixing components (such as...) Figure 3 4) Symmetrically assembled at both ends of the rotating shaft, and reinforcedly connected to the backrest frame. With the transmission advantage of the screw, which can "exchange small force for large force", the backrest can rotate smoothly around the upper rotating shaft at a maximum load of 150kg. After stopping, the screw can lock the posture immediately through its self-locking characteristic. 2. The central support column is vertically welded to the core area at the bottom of the seat cushion, and to the upper rotating axis of the backrest (such as...). Figure 3 The middle 5) and backrest frame form a triangular stable support; it is reinforced with high-strength alloy steel fully welded, which can stably withstand the maximum load of 150kg, effectively offsetting the lateral torque during rotation, ensuring no shaking when the human body is fully loaded, and forming a dual adaptation of structure and power with the drive characteristics of the trapezoidal screw motor.

[0034] 3. Backrest rocking drive assembly: The trapezoidal lead screw motor moves synchronously with the backrest cushion (e.g., Figure 3 (1), its output end is connected to a fixed gear assembly (such as...) Figure 3 2) Precise meshing (gears remain stationary, motor dynamically moves in tandem with the cushion); the motor outputs power at a rated torque of 40 N·m, utilizing the transmission advantage of the lead screw to "exchange small force for large force," and the cushion's forward swing supports the pillar (e.g., Figure 2 12) Transmitting thrust: Due to the combination of fixed gears and a moving motor, there is no lateral force to cancel out the power transmission, ensuring smooth and uninterrupted transmission under a rated load of 150kg.

[0035] 4. Backrest rocking control and locking: Based on a fixed backrest axis (such as...) Figure 3 The core fulcrum is 3 and 4), and the self-locking characteristic of the trapezoidal screw immediately locks the posture of the cushion after it stops rotating, preventing accidental shaking. At the same time, the motor and the cushion maintain a relatively fixed position, further ensuring transmission stability and safety of use.

[0036] - Execution logic: 1. Backrest rotation function: Under normal conditions, it is limited to a range of 120° to the left and right, which is suitable for daily interaction and light scene switching needs; in special demonstration scenarios, the main control unit unlocks the limit and can achieve 360° rotation, which works in conjunction with the bottom rotation module to form a compound rotation action. 2. Backrest back and forth rocking function: After receiving the command from the main control unit, the trapezoidal screw motor drives the backrest to swing forward and lift the support column through the gear assembly, causing the backrest to rock back and forth around the fixed axis. In normal mode, the maximum rocking angle is limited to 50° to ensure safety. In extreme mode, the maximum rocking angle is 90°. The overall transmission is smooth without lateral force, the start and stop response is sensitive and the posture locking is reliable.

[0037] (iv) Lifting and Adjustment Module - Core component: Lifting drive motor (such as...) Figure 2 3) Vertical main load-bearing shaft (such as Figure 2 4, 5), rising steel columns (such as...) Figure 2 6) Guiding components; - Installation Notes: 1. The vertical main load-bearing shaft adopts an "inner-outer" double-shaft nested structure, with the outer core main load-bearing shaft (such as...) Figure 2 5) Core load-bearing shaft inside the package (such as...) Figure 2 (4), and rises and falls synchronously with it; built-in lifting steel column (such as Figure 2 (6) is a robust load-bearing structure, with springs (such as...) Figure 2 The part above (7) is a solid structure (used to support and enclose the rotating shaft, such as...) Figure 2 Middle 9 / Figure 3 (5) The part below the spring is a hollow structure. The overall mechanical strength must meet the requirements of a conventional load-bearing capacity of 120kg (preferred) and an ultimate load-bearing capacity of 150kg to support the main weight of the seat and the human body; (The light green outer skin in the attached picture is not actually transparent, and the picture shows the internal structure) 2. The lifting drive uses a trapezoidal screw motor (such as...). Figure 2 (3), rated torque 50 N·m, motor rotates with the seat rocking shaft (e.g. Figure 2 (17) Installed synchronously, with a self-locking function when the rotation stops (no settling after power failure); the lifting stroke is set to 20-50cm (not a fixed height, supports flexible adjustment), and is equipped with a guide component to ensure smooth lifting without deviation; - Operating logic: The height can be dynamically adjusted in real time based on XR / game scene feedback signals to adapt to scene interaction needs; universal shock-absorbing springs (such as...) Figure 2 7) Auxiliary load-bearing structure, working in conjunction with the main load-bearing structure to meet the load-bearing requirements of 120kg for conventional loads and 150kg for extreme loads.
