A falling object simulation experience unit and a VR full-sense training cabin

Abstract

This invention discloses a falling object simulation experience unit and a VR immersive training cabin, belonging to the field of safety training technology. The falling object simulation experience unit includes a drive mechanism, a traction mechanism, and a falling object module located above the user. The traction mechanism includes a traction rope, and the falling object module is suspended and connected to the drive mechanism via the traction rope, allowing the drive mechanism to move the falling object module up and down. It also includes a tension detection mechanism, which detects the tension of the traction rope. When the falling object module moves downward and impacts the user, the tension detection mechanism detects that the traction rope is slack, controlling the drive mechanism to stop, thus stopping the falling object module from moving downward. This allows the falling object module to maintain contact with users of different heights upon impact. In this way, while preventing the falling object module from falling further and causing entanglement, it also eliminates the need to measure the user's height to adjust the height of the falling object module.

Description

Technical Field

[0001] This invention relates to the field of safety training technology, and more specifically, to a falling object simulation experience unit and a VR immersive training cabin. Background Technology

[0002] In recent years, with the popularization of safety education, VR full-sensory training cabins have gradually emerged in some industrial enterprises and training venues. They present the injuries, coping methods and prevention knowledge caused by one or more common accidents through sensory experiences such as sight, hearing, smell and touch. That is, through scenario simulation, prop rehearsal and other methods, they are presented under human control, giving people an immersive and realistic audio-visual experience. This not only increases the trainees' enthusiasm for learning, but also improves the effectiveness of occupational safety training.

[0003] High-altitude falling object simulation is an important component of VR full-sensory training cabins. Chinese patent CN 220730993 U discloses a helmet impact simulation mechanism. The simulation device has a first, second, and third simulation chamber inside. Each simulation chamber is fixedly installed with a first driving component, which is equipped with a winch. A steel cable is connected to the winch, and a counterweight is connected to the end of the steel cable. A switch is installed in each simulation chamber. The user operates the switch to control the descent and ascent of the counterweight. When the counterweight impacts the helmet, the user needs to operate the switch in time to shut off the first driving component. In practical applications, due to the user's reaction speed, the steel cable is prone to being released too much or too little. If it is released too little, the counterweight will not be able to impact the user. If it is released too much, it may become entangled and affect normal operation.

[0004] Chinese patent CN209281740U discloses a VR-linked high-altitude fall experience device, including an execution unit and a control unit. The execution unit is directly installed on the ceiling of the experience hall. A steel cable leading from the execution unit is connected to the falling object via a reversing wheel. A stepping first drive unit drives the steel cable reel to rotate forward at a set speed. Once the timed limit is reached, the stepping first drive unit stops rotating, and the falling object stops falling. It is evident that the falling distance of the falling object is controlled by the running time of the stepping first drive unit. If the user is tall, the steel cable may be released too far, easily causing entanglement. If the user is short, the steel cable release distance may be insufficient, and the falling object may not hit the user, thus preventing the user from experiencing the impact of the falling object.

[0005] Therefore, the present invention aims to provide a falling object simulation experience unit and a VR full-sensory training cabin to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a falling object simulation experience unit and a VR full-sensory training cabin to solve the problems mentioned in this application.

[0007] To achieve the above objectives, the present invention provides a falling object simulation experience unit, comprising a drive mechanism, a traction mechanism, and a falling object module located above the user. The traction mechanism includes a traction rope, and the falling object module is suspended and connected to the drive mechanism via the traction rope, so that the drive mechanism can move the falling object module up and down. The present invention is characterized in that... It also includes a tension detection mechanism, which is used to detect the tension of the traction rope; when the falling object module moves downward and hits the user, the tension detection mechanism detects that the traction rope is in a slack state, so as to control the drive mechanism to stop running, thereby stopping the falling object module from moving downward, and thus enabling the falling object module to maintain contact with users of different heights at the time of impact.

[0008] Furthermore, the tension detection mechanism includes a micro switch and a trigger component disposed on the movement path of the traction rope. The trigger component is configured to adjust the micro switch according to the tension state of the traction rope, so that the micro switch controls the operation of the drive mechanism.

[0009] Furthermore, the traction rope includes a horizontal section connected to the drive mechanism and a vertical section suspended and connected to the falling object module; the tension detection mechanism is used to detect the tension of the horizontal section.

[0010] Furthermore, the traction mechanism also includes a reversing wheel assembly mounted on the mounting base plate, the reversing wheel assembly being used to slide in conjunction with the traction rope to change the direction of the traction rope, thereby forming the horizontal section and the vertical section.

[0011] Furthermore, the falling object module includes a striking plate and a telescopic component, the telescopic component being used to connect the mounting base plate and the striking plate, and the vertical section being connected to the telescopic component or the striking plate.

[0012] Furthermore, the traction rope includes a main rope body and two branch rope bodies disposed at one end of the main rope body. The drive mechanism is connected to the main rope body, and the branch rope bodies are connected to the falling object module.

[0013] Furthermore, a reversing wheel assembly is provided on each side of the main rope in the width direction. The reversing wheel assembly is used to slide with the branch rope to change the direction of the branch rope.

[0014] Furthermore, the reversing pulley assembly includes a horizontal pulley and a vertical pulley arranged along the width direction of the main rope body. The horizontal pulley is arranged close to the main rope body, and the tension detection mechanism is arranged between the horizontal pulley and the vertical pulley.

[0015] Furthermore, the triggering component includes a torsion spring and a retaining member. The retaining member has a first end and a second end that are correspondingly arranged, and the middle part of the retaining member is hinged to the fixed bracket. The torsion spring is disposed on the fixed bracket and located below the first end. When the traction rope is in a tensioned state, the first end presses down on the torsion spring, and the second end separates from the micro switch. When the traction rope is in a slack state, the torsion spring rebounds, so that the second end presses down on the micro switch.

[0016] A VR full-sensory training cabin includes a cabin frame and a falling object simulation experience unit as described above. The cabin frame includes a cabin floor, a cabin top, side beams, and a support module. The support module is disposed between the cabin top and the cabin floor, and the side beams are disposed on the support module. The falling object simulation experience unit is located on the lower end surface of the cabin roof, and at least one of the following is also provided within the cabin frame: a motion platform, an environmental simulation unit, and an injury simulation unit.

[0017] Furthermore, the cabin top includes a left cabin top module, a middle cabin top module, and a right cabin top module; and / or The hull includes a left hull module, a middle hull module, and a right hull module; and / or The support module includes a left front column, a right front column, a left rear column, and a right rear column; and / or The side beam includes a left beam module and a right beam module. The left beam module is disposed between the left front column and the left rear column, and the right beam module is disposed between the right front column and the right rear column.

[0018] Furthermore, the environmental simulation unit includes at least one of a water mist simulation module, a cold air simulation module, a hot air simulation module, an odor simulation module, and a flame simulation module; and / or The injury simulation unit includes at least one of the following: a crush simulation module, an electric shock simulation module, a gear simulation module, a pulley simulation module, and a lateral impact module.

[0019] Furthermore, the water mist simulation module includes: a water storage container disposed within the support module; a water pump connected to an inlet pipe and an outlet pipe, the inlet pipe being inserted into the water storage container, and the outlet pipe being provided with a first nozzle for spraying water into the cabin frame through the first nozzle; and a return pipe connected to the outlet pipe and the water storage container through a second nozzle, the second nozzle being located below the first nozzle, and the diameter of the second nozzle being slightly larger than the diameter of the first nozzle.

[0020] Furthermore, the flame simulation module includes: a lower water tank disposed within the hull; a water mist generating module disposed within the lower water tank; a mounting base disposed at the opening of the lower water tank and having an air outlet; a blowing module disposed on the mounting base for blowing air into the lower water tank so that the water mist generated by the water mist generating module diffuses outward through the air outlet; a lighting module located on the mounting base and disposed along the air outlet; and an upper cover plate covering the mounting base, the upper cover plate having a water mist outlet and a lighting outlet.

[0021] Furthermore, both the left and right modules of the hull are equipped with flame simulation modules, and dark background panels are provided on the sides of the two flame simulation modules that are far apart from each other.

[0022] Furthermore, it also includes a VR module and a control unit, wherein the control unit is communicatively connected to the falling object simulation experience unit, the environment simulation unit, the injury simulation unit, the VR module, and the motion platform.

[0023] Compared with existing technologies, the falling object simulation experience unit and VR full-sensory training cabin provided in this application have the following beneficial effects: 1. The present invention provides a falling object simulation experience unit, which drives a traction rope to move up and down through a drive mechanism, thereby causing the falling object module to move up and down relative to the user. When the falling object module moves downward and hits the user's head, a tension detection mechanism detects that the traction rope is in a slack state. At this time, the drive mechanism stops running, thereby stopping the falling object module from moving downward. For users of different heights, the falling object module can stop moving in time when it hits the user's head. Therefore, without needing to detect the user's height to adjust the descent height of the falling object module, it can also effectively prevent the traction rope from being released too much and causing entanglement, ensuring that the falling object module can hit the user.

[0024] 2. The present invention provides a falling object simulation experience unit in which, when the traction rope breaks, the telescopic component can connect the mounting base plate and the impact plate to prevent the impact plate from falling directly and hitting the user.

[0025] 3. The present invention provides a falling object simulation experience unit, wherein the traction rope includes a main rope and two branch ropes connected to one end of the traction rope, which can effectively reduce the possibility of the falling object module rotating or swaying during the lifting process, ensuring that it can hit the experiencer vertically and accurately, thereby improving the consistency and safety of the impact experience.

[0026] 4. The falling object simulation experience unit provided by the present invention, by setting a reversing wheel group on both sides of the width direction of the main rope, and setting the tension detection mechanism between the horizontal pulley and the vertical pulley, allows each branch rope to slide and cooperate with the horizontal pulley and the vertical pulley in sequence along the width direction of the main rope after being led out from the main rope. This can effectively improve the tension of the branch rope, that is, effectively improve the tension change of the branch rope, so that the tension detection mechanism can detect the subtle changes of the traction rope to the greatest extent, and improve the sensitivity of detecting the tension of the traction rope.

[0027] 5. The VR full-sensory training cabin provided by the present invention greatly enriches the sensory dimensions of training and the coverage of dangerous scenarios by adding at least one of a motion platform, an environmental simulation unit, and an injury simulation unit to the cabin frame. The trainees can not only feel the impact of falling objects, but also experience ground shaking, various harsh environments, or different types of mechanical injuries, thereby achieving realistic simulation of complex and comprehensive dangerous scenarios and multi-sensory full-scene experience, significantly improving the comprehensiveness of training.

[0028] 6. The VR full-sensory training cabin provided by the present invention further subdivides the cabin top, cabin bottom, support module and side beam into multiple assembleable modules, realizing the modular design of the cabin frame, enabling standardized production and transportation of each component, and flexible assembly or disassembly according to site requirements, which greatly reduces manufacturing, logistics and deployment costs.

[0029] 7. This invention provides a VR full-sensory training cabin. By setting up a return pipe and a second nozzle, and placing the second nozzle below the first nozzle with a slightly larger diameter, a local water circulation path is formed. When the water pump stops working, the water remaining in the outlet pipe that has not yet been sprayed can be recycled to the water storage container through the return pipe. This not only saves water resources but also reduces the accumulation of water in the cabin frame, ensuring the experience and safety of the user.

[0030] 8. The present invention provides a VR full-sensory training cabin in which the light module emits light to illuminate the water mist escaping through the water mist outlet and projects it onto a dark background to present a flame-like effect. The dark background contrasts strongly with the water mist and light, making the outline of the "flame" clearer, the color more vivid, and the three-dimensionality and realism stronger. Moreover, the dark background is set on the side where the two flame simulation modules are far apart from each other, which can play a role in blocking the wind and ensuring the effect of simulating flames.

[0035] See the instruction manual appendix Figures 5 to 8 The present invention provides a falling object simulation experience unit 2, comprising a drive mechanism 22, a traction mechanism 23, and a falling object module 21 located above the user. The traction mechanism 23 includes a traction rope 231, through which the falling object module 21 is suspended and connected to the drive mechanism 22, allowing the drive mechanism 22 to move the falling object module 21 up and down to adjust the distance between the falling object module 21 and the user. Correspondingly, the falling object simulation experience unit also includes a tension detection mechanism 24, which detects the tension of the traction rope 231. During operation, when the drive mechanism 22 moves the falling object module 21 up or down, the traction rope 231 is taut due to the pulling force of the falling object module 21. When the falling object module 21 moves downward and eventually impacts the user, the traction rope 231 instantly slackens due to the obstruction caused by the falling object module 21. At this time, the tension detection mechanism 24 can immediately detect that the traction rope 231 is slackened and immediately control the drive mechanism 22 to stop operating. The stopping of the drive mechanism 22 causes the traction rope 231 and the falling object module 21 to stop moving downwards, thus completing an impact simulation. Understandably, in existing technologies, devices that lower a weight using a drive mechanism rely on human reaction, timed control, or height measurement sensors to determine the descent distance. Human reaction requires the user to control the switch based on their own perception, while timed control requires the weight to stop falling after a fixed time. Both methods are prone to problems such as the steel cable being too long and tangling, or too short and the weight failing to reach the user. Therefore, some devices use height measurement sensors to measure the user's height, calculate the distance between the weight and the user, and then control the drive mechanism to lower the weight so that it hits the user's head. However, this method still has significant drawbacks. Firstly, it requires high-quality hardware and precise coordination (a height measurement sensor and an encoder for the drive mechanism are needed). Secondly, the height measurement sensor has inherent errors, which also affect the drive mechanism's control of the weight's descent distance, resulting in low accuracy in the descent height and the continued risk of the steel cable becoming tangled or the weight failing to reach the user. In this embodiment, the traction rope 231 drives the falling object module 21 to move up and down. For participants of different heights, the falling object module 21 can impact the participant's head. At this time, the tension detection mechanism 24 detects that the traction rope 231 changes from a tensioned state to a slack state, and then controls the drive mechanism 22 to stop running, thereby stopping the traction rope 231 and the falling object module 21 from moving downward. Therefore, for participants of different heights, only the tension detection mechanism 24 needs to be set up, without measuring the participant's height. The falling object module 21 can impact the participant's head, ensuring that participants of different heights can all receive the impact of the falling object module 21. Moreover, when the falling object module 21 impacts the participant, the traction rope 231 can stop in time to prevent excessive release and entanglement.

[0036] Furthermore, in existing technologies, when objects fall freely, no driving mechanism is required to drive the object. For users of different heights, sensors are needed to measure their height, and the distance between the falling object and the user needs to be adjusted accordingly to ensure the object impacts the user with the same speed and force. In this embodiment, however, the driving mechanism 22 enables the falling object module 21 to descend at the same speed, ensuring that users of different heights receive the same impact force.

[0037] In one embodiment, see the specification. Figures 5 to 8 This embodiment further describes the traction rope 231. The falling object simulation experience unit also includes a mounting base plate 26. The traction rope 231 includes a horizontal section 2311 and a vertical section 2312. The horizontal section 2311 is arranged along the mounting base plate 26 and is used to connect to the drive mechanism 22. The vertical section 2312 is arranged perpendicular to the mounting base plate 26 and is used to connect to the falling object module 21.

[0038] Furthermore, the traction mechanism 23 also includes a reversing wheel assembly disposed on the mounting base plate 26. The reversing wheel assembly slides in conjunction with the traction rope 231 to change the direction of the traction rope 231, thereby forming a horizontal section 2311 and a vertical section 2312. Even further, a set of reversing wheel assemblies is disposed on the mounting base plate 26, and the traction rope 231 slides in conjunction with the reversing wheel assembly, causing one end of the traction rope 231 to extend downward under the action of the reversing wheel assembly, thereby forming a horizontal section 2311 and a vertical section 2312 on both sides of the reversing wheel assembly. It is understood that the tension detection mechanism 24 can also be used to detect the tension state of the vertical section 2312. Preferably, the tension detection mechanism 24 is disposed corresponding to the horizontal section 2311, with the horizontal section 2311 directly pressing down on the tension detection mechanism 24 for better sensitivity. Preferably, to further improve the stability of the traction rope 231 during vertical movement, the traction rope 231 includes a main rope body 2313 and two branch rope bodies 2314 disposed at one end of the main rope body 2313. The drive mechanism 22 is connected to the main rope body 2313, and the two branch rope bodies 2314 are connected to the falling object module 21. A reversing pulley set is respectively provided on both sides of the main rope body 2313 in the width direction. The reversing pulley set slides with the branch rope body 2314 to change the direction of the branch rope body 2314. The reversing pulley set includes a horizontal pulley 232 and a vertical pulley 233 disposed along the width direction of the main rope body 2313. The horizontal pulley 232 is disposed close to the main rope body 2313, and the tension detection mechanism 24 is disposed between the horizontal pulley 232 and the vertical pulley 233. One end of the branch rope 2314 first slides with the horizontal pulley 232, so that the branch rope 2314 slides along the width direction of the main rope 2313 and slides with the vertical pulley 233, thereby allowing the branch rope 2314 to extend downward and connect with the falling object module 21.

[0039] Understandably, the falling object module 21 is suspended at a single point only through the main rope 2313 of the traction rope 231. During the descent, it is prone to swaying, tilting, and deflection. Swaying can cause false tension or slack in the rope, interfering with detection. In this invention, by setting two branch ropes 2314 connected to the falling object module 21, the falling object is suspended symmetrically at two points, resulting in more stable movement, less swaying, ensuring that it can hit the user vertically and accurately, and reducing detection interference.

[0040] The present invention provides a falling object simulation experience unit, which includes a reversing pulley group on each side of the main rope 2313 in the width direction, and at least one tension detection mechanism 24 for each branch rope 2314, with the tension detection mechanism 24 positioned between a horizontal pulley 232 and a vertical pulley 233. After each branch rope 2314 is led out from the main rope 2313, it slides and engages with the horizontal pulley 232 and the vertical pulley 233 sequentially along the width direction of the main rope 2313, which can effectively improve the tension of the branch rope 2314, that is, effectively improve the sensitivity of the tension change of the branch rope 2314, so that the tension detection mechanism 24 can detect the slightest changes in the traction rope 231 to the greatest extent, thereby improving the sensitivity of signal detection. Therefore, when the falling object module 21 hits the user's head, the branch rope 2314 can immediately change from a tensioned state to a relaxed state, which greatly shortens the response time of the branch rope 2314 and enables the tension detection mechanism 24 to immediately detect the change in the state of the branch rope 2314.

[0041] In one embodiment, see the appendix to the specification. Figure 7 and 8 The drive mechanism 22 includes a first drive member 221 and a take-up drum 222. The take-up drum 222 is located at the output end of the first drive member 221 and is used to connect to the traction rope 231. The rotation of the take-up drum 222 realizes the winding and unwinding of the traction rope 231, thereby driving the falling object module 21 to move up and down. Preferably, the drive mechanism 22 also includes a guide wire frame. The first drive member 221 is fixed on the guide wire frame. The guide wire frame is provided with a guide wire hole located above the take-up drum 222. One end of the traction rope 231 passes through the guide wire hole and is connected to the take-up drum 222. When the first drive member 221 drives the take-up drum 222 to rotate, the traction rope 231 passes through the guide wire hole and winds around the take-up drum 222, or is released from the take-up drum 222.

[0042] Furthermore, an upper limit sensor 251 and a lower limit sensor 252 are provided on the moving path of the traction rope 231. Two limit brackets 261 are provided on the mounting base plate 26. The main rope body 2313 passes through the limit brackets 261 respectively, and the upper limit sensor 251 and the lower limit sensor 252 are respectively provided on the limit brackets 261. A stop block 253 is provided on the main rope body 2313 of the traction rope 231. The stop block 253 is used to trigger the upper limit sensor 251 and the lower limit sensor 252 so that the drive mechanism 22 stops running.

[0043] In practical production applications, both the upper limit sensor 251 and the lower limit sensor 252 can be configured as microswitches. Correspondingly, the upper limit sensor 251 and the lower limit sensor 252 are used to limit the highest and lowest points of the falling object module 21, respectively. When the falling object module 21 rises or falls to its limit position, the impact block 253 triggers the corresponding limit sensor, causing the drive mechanism 22 to stop operating. This effectively limits the travel of the falling object module 21, ensuring that participants at both the highest and lowest points experience the impact of the falling object module 21. For details, please refer to the instruction manual. Figure 8 Two sliding plates 262 are correspondingly arranged on both sides of the limiting bracket 261 along the extension direction of the main rope 2313. The two sliding plates 262 are connected by two corresponding connecting shafts 263, which pass through the limiting bracket 261 to movably set the sliding plates 262 on the limiting bracket 261. The main rope 2313 passes through the sliding plates 262 and the limiting bracket 261. A stop block 253 is arranged on the part of the main rope 2313 between the upper limit sensor 251 and the lower limit sensor 252, and a spring is also sleeved on the outside of the connecting shaft 263. For the upper limit sensor 251, one end of its spring abuts against the limiting bracket 261, and the other end of the spring abuts against the sliding plate 262 away from the drive mechanism 22. The button of the micro switch is located below the sliding plate 262 near the drive mechanism 22, and the trigger switch of the micro switch is tilted upward in the direction near the drive mechanism 22. For the lower limit sensor 252, one end of its spring abuts against the limit bracket 261, and the other end of the spring abuts against the sliding plate 262 away from the branch rope 2314. The button of the micro switch is located below the sliding plate 262 near the branch rope 2314, and the button of the micro switch is tilted upward in the direction near the branch rope 2314.

[0044] To simplify the explanation, the sliding plate 262 of the upper limit sensor 251 closest to the drive mechanism 22 is designated as the first sliding plate, and the sliding plate 262 furthest from the drive mechanism 22 is designated as the second sliding plate. When the falling object module 21 reaches its highest point, the impact block 253 collides with the second sliding plate, compressing the spring. Due to the upward tilt of the micro switch button, the first sliding plate moves towards the drive mechanism 22, pressing down the micro switch button and triggering it. Conversely, when the falling object module 21 descends from its highest point, the impact block 253 moves away from the second sliding plate, and the first sliding plate, under the restoring force of the spring, moves away from the drive mechanism 22, thus releasing the first sliding plate from its effect on the micro switch.

[0045] Furthermore, the falling object module 21 includes an impact plate 211 and a telescopic member 212. The telescopic member 212 connects the mounting base plate 26 and the impact plate 211. The vertical section 2312 is connected to the telescopic member 212 or the impact plate 211, allowing the impact plate 211 to move smoothly in the vertical direction under the guidance of the telescopic member 212. Simultaneously, lifting control is achieved through the traction of the traction rope 231. The telescopic member 212 not only serves as a guide but also limits the horizontal displacement of the impact plate 211, ensuring its stability during movement. Additionally, in actual production applications, to reduce the impact force of the falling object module 21 and ensure the safety of the user, the user often needs to wear a safety helmet, which is inconvenient and affects operation. Preferably, a flexible buffer layer is provided on the side of the impact plate 211 closest to the user to reduce the force when the impact plate 211 hits the user's head. Furthermore, the telescopic member 212 is generally configured as a scissor-type telescopic arm.

[0046] In this embodiment, on the one hand, when the participant's position deviates, or when the participant needs to move or lower their head due to training requirements, the relatively large area of ​​the impact plate 211 (which can be set according to the internal space of the cabin frame, generally a rectangular plate of 1 meter x 1 meter) effectively reduces the possibility that the falling object module 21 will not hit the participant. On the other hand, the telescopic component 212 provides stable guiding support for the impact plate 211, ensuring that the impact plate 211 will not shift horizontally or rotate during the lifting and lowering process, thus guaranteeing the accuracy and safety of the impact plate 211 when it comes into contact with the participant. In addition, when the traction rope 231 is connected to the impact plate 211, the traction rope 231 and the telescopic component 212 work together to connect the impact plate 211, preventing the impact plate 211 from falling directly and hitting the participant if the traction rope breaks.

[0047] In one embodiment, the tension detection mechanism 24 is further described. The tension detection mechanism 24 includes a micro switch 242 and a trigger component 241 disposed on the moving path of the traction rope 231. The trigger component 241 adjusts the micro switch 242 according to the tension state of the traction rope 231, thereby controlling the operation of the drive mechanism 22. Specifically, the micro switch 242 is disposed on a fixed bracket 243, and the trigger component 241 is a torsion spring disposed on the fixed bracket via a positioning pin. When the traction rope 231 moves up and down, the traction rope 231 is under tension due to the pulling force of the falling object module 21. The traction rope 231 can press down on the torsion spring, causing the torsion spring to press down on the micro switch 242. At this time, the micro switch 242 is in the triggered state, and the drive mechanism 22 operates normally. When the falling object module 21 hits the user's head, the traction rope 231 is in a slack state, and the torsion spring is not subjected to the downward pressure of the traction rope 231. The torsion spring rebounds, causing the micro switch 242 to reset. At this time, the micro switch 242 controls the drive mechanism 22 to stop running.

[0048] In one embodiment, see the specification. Figure 7 The trigger assembly 241 includes a torsion spring 244 and a retaining member 245. A micro switch 242 is mounted on a fixed bracket 243. The torsion spring 244 is mounted on the fixed bracket 243 via a locating pin and is located above the micro switch 242. A rotating shaft is hinged to the middle of the retaining member 245 to rotatably mount the retaining member 245 on the fixed bracket 243. The retaining member 245 has a first end and a second end correspondingly positioned. The first end is located above the torsion spring 244, and the second end is located above the micro switch 242. When the retaining member 245 rotates, the first end and the second end can rotate with the retaining member 245 to adjust the distance between the first end and the torsion spring 244, and the distance between the second end and the micro switch 242. When the traction rope 231 is taut, it presses down on its first end, which in turn presses down on the torsion spring 244, compressing the spring. At this time, the holding member 245 is horizontal, and its second end does not engage with the micro switch 242. The traction rope 231 continues to move downward along the holding member 245 until it becomes slack and no longer pulls down. The torsion spring 244 then rebounds, and the holding member 245 rotates under the action of the spring, causing its second end to press down and trigger the micro switch 242. The micro switch 242 then controls the drive mechanism 22 to stop operating.

[0049] Understandably, in this embodiment, the trigger component 241 includes a torsion spring 244 and a retaining member 245, with the retaining member 245 forming a lever structure. When the traction rope 231 is in a tensioned state, the torsion spring 244 is compressed, and the traction rope 231 is subjected to the restoring force of the torsion spring 244, which can further increase the tension of the traction rope 231. On the one hand, when the traction rope 231 suddenly slackens, the torsion spring 244 can release a greater restoring force. Through the amplification effect of the lever structure, the second end triggers the micro switch 242 with a faster and more powerful action, thereby shortening the system response time and improving the timeliness of safety protection. On the other hand, when the traction rope 231 is obstructed, only a small force is needed to loosen the traction rope 231, further improving the sensitivity of the tension detection mechanism 24, thereby further preventing the traction rope 231 from being released too far.

[0050] Preferably, a groove is provided on the side of the holding member 245 near the traction rope 231, allowing the traction rope 231 to press down on the holding member 245 through the groove and move relative to it, thereby reducing slippage during transmission and improving the accuracy of position control and motion transmission. Furthermore, a mounting groove is formed on the bottom wall of the second end of the groove, within which a guide wheel and a guide bracket are installed. The guide wheel is rotatably mounted on the guide bracket, which is connected to the bottom of the mounting groove via a spring. When the traction rope 231 presses down on the holding member 245, the first end of the traction rope 231 presses down, and the second end rises accordingly. The guide wheel slides against the traction rope 231, compressing the spring to further increase the tension of the traction rope 231. When the traction rope 231 loosens, the holding member 245 can rotate rapidly under the restoring force of the torsion spring 244 and the spring, further reducing the reaction time of the tension detection mechanism 24.

[0051] Compared to existing technologies that use a drive mechanism to lower a heavy object and a sensor to measure its height, the falling object simulation experience unit provided in this embodiment has improved the stopping response time of the falling object module 21, the probability of the traction rope 231 getting tangled, and the probability of impact.

[0052]

[0053] It is understood that the drive mechanism 22 drives the falling object module 21 to move downward. Only when the falling object module 21 hits the head of the user can the traction rope 231 be switched to a slack state. Only then can the tension detection mechanism 24 detect that the traction rope 231 is in a slack state. Therefore, the probability of the falling object simulation experience unit provided in this embodiment hitting the user's head is 100%.

[0054] Accordingly, when the falling object module 21 impacts the user's head, the flexible buffer layer located below the impact plate 211 first contacts the user's head. The flexible buffer layer can be compressed, slowing down the descent speed of the impact plate 211. Since the rotation speed of the first drive component 221 remains unchanged, the traction rope 231 will be in a slack state at this time. The impact stop response time from when the traction rope 231 is in a slack state to when the tension detection mechanism 24 controls the first drive component 221 to stop working is generally 0.3s to 0.5s. During this period, the flexible buffer layer is further compressed, and the impact plate 211 descends further, thereby further preventing the traction rope 231 from becoming entangled.

[0055] See instruction manual Figures 1 to 4 , Figures 9 to 14This embodiment provides a VR full-sensory training cabin, including the falling object simulation experience unit described in the above embodiment, and a cabin frame 1. The cabin frame 1 constitutes the frame structure of the entire training cabin, and the falling object simulation experience unit is fixedly installed inside the cabin frame 1.

[0056] Furthermore, the hull frame 1 includes a bottom 11, a top 12, side beams 13, and support modules 14. The support modules 14 are vertically arranged between the top 12 and the bottom 11, forming the four corner supports of the hull frame 1. The side beams 13 are horizontally fixed on the support modules 14, connecting the front and rear support structures to enhance overall rigidity.

[0057] Specifically, the top 12 includes a left top module 121, a middle top module 122, and a right top module 123. Correspondingly, the mounting base plate 26 is installed on the lower end face of the middle top module 122. The bottom 11 includes a left bottom module 111, a middle bottom module 112, and a right bottom module 113. The support module 14 includes a left front column 141, a right front column 142, a left rear column 143, and a right rear column 144. The side beams 13 include a left side beam module 131 and a right side beam module 132. The left side beam module 131 is disposed between the left front column 141 and the left rear column 143, and the right side beam module 132 is disposed between the right front column 142 and the right rear column 144. See the specification for details. Figure 1 Two corresponding guardrail posts 161 are installed between the left front post 141 and the left rear post 143, and between the right front post 142 and the right rear post 144. A horizontally arranged guardrail support rod 162 is also installed between the two guardrail posts 161. A decorative piece 163, which can be made of black acrylic glass, is installed below the guardrail support rod 162. Two corresponding guardrail posts 161 are also installed between the left front post 141 and the right front post 142. A horizontally arranged guardrail support rod 162 is installed between one guardrail post 161 and the left front post 141, and between the other guardrail post 161 and the right front post 142. A decorative piece 163 is installed below the guardrail support rod 162. A magnetic door 164 is also installed between the two guardrail posts 161.

[0058] Understandably, by further subdividing the top 12, bottom 11, support module 14, and side beam 13 into multiple modular components, the modular design of the cabin frame 1 is achieved. This enables standardized production and transportation of each component, and allows for flexible assembly or disassembly according to site requirements, significantly reducing manufacturing, logistics, and deployment costs.

[0059] Furthermore, the VR immersive training cabin also includes at least one of a motion platform 3, an environmental simulation unit, and an injury simulation unit to provide a multi-dimensional, immersive safety experience. By integrating multiple simulation units within the VR immersive training cabin, trainees can experience various dangerous scenarios, enhancing the richness of the training and achieving a fully immersive, "being there" experience. Specifically, the environmental simulation unit includes at least one of a water mist simulation module 41, a cold air simulation module 42, a hot air simulation module 43, an odor simulation module 44, and a flame simulation module 45.

[0060] Preferably, to maximize the training effect for participants, the water mist simulation module 41, the cold air simulation module 42, the hot air simulation module 43, and the odor simulation module 44 are housed within the support module 14. (See [link]). Figure 3 A water mist simulation module 41, a cold air simulation module 42, a hot air simulation module 43, and an odor simulation module 44 are installed in both the left rear column 143 and the right rear column 144. The cold air simulation module 42, the hot air simulation module 43, and the odor simulation module 44 adopt existing technology and will not be described in detail here.

[0061] The water mist simulation module 41 includes a water storage container 411 and a water pump 412 disposed within the support module 14. The inlet of the water pump 412 is connected to the water storage container 411 via an inlet pipe 413, and the outlet is connected to an outlet pipe 414. A first nozzle 415 is installed at the end of the outlet pipe 414, atomizing the water flow and spraying it into the interior of the cabin frame 1 to simulate rain, fog, or water vapor environments. Furthermore, the module also includes a return pipe 416 and a second nozzle 417. The return pipe 416 is connected to the outlet pipe 414 and the water storage container 411 via the second nozzle 417, forming a circulating water path. The second nozzle 417 is located below the first nozzle 415, and the diameter of the second nozzle 417 is slightly larger than the diameter of the first nozzle 415. The diameter d1 of the first nozzle 415 satisfies the following condition: 0.4mm≤d1≤0.5mm, and the diameter d2 of the second nozzle 417 satisfies the following condition: 0.5mm<d2≤1.0mm.

[0062] It should be noted that the water mist simulation module 41 is used to simulate rainy weather conditions, and can also be used to simulate the working state and effect of a sprinkler fire extinguishing system in a fire scenario. Water mist is generally pumped out by a water pump generating negative pressure. However, after the water pump is turned off, the residual water pressure will still pump water out of the pipes. This water will accumulate inside the equipment compartment, easily leading to electric shock, equipment damage, and personnel slipping. In existing technologies, to solve this problem, a return pipe, a one-way valve, and an air pump are often installed. The air pump and return pipe then suck out and empty the residual liquid in the pipes. However, this structure is relatively complex and costly.

[0063] Understandably, if the diameter of the first nozzle 415 is too large, although water can be pumped out smoothly, the atomization effect is poor, resulting in more water being sprayed out and more likely to accumulate and remain. If the diameter of the first nozzle 415 is too small, greater pressure is required to spray the water, placing higher demands on the water pump 412 and the overall pipeline, and correspondingly increasing costs. Therefore, in practical applications, the diameter d1 of the first nozzle 415 is set between 0.4mm and 0.5mm. Correspondingly, the second nozzle 417 mainly serves as a pressure divider and overflow. If the diameter of the second nozzle 417 is too small (smaller than the diameter of the first nozzle 415), it is difficult to form a pressure difference between the first nozzle 415 and the second nozzle 417 when the water pump 412 stops, and residual water will still drip out from the first nozzle 415. If the diameter of the second nozzle 417 is too large, it will affect the smooth spraying of water from the first nozzle 415. Therefore, in practical applications, the diameter d2 of the second nozzle 417 is generally set between 0.5mm and 1.0mm, so that the diameter of the second nozzle 417 is slightly larger than that of the first nozzle 415, forming a local water circulation path.

[0064] In this embodiment, the second nozzle 417 functions as a pressure-splitting overflow. When the water pump 412 is working, most of the water is sprayed into the cabin frame 1 through the first nozzle 415, while a small portion enters the water storage container 411 through the return pipe 416. When the water pump 412 stops working, because the second nozzle 417 is located below the first nozzle 415 and its diameter is larger than that of the first nozzle 415, the water remaining in the outlet pipe 414 that has not yet been sprayed out is recovered into the water storage container 411 through the return pipe 416 under the pressure difference. This not only saves water resources but also reduces the accumulation of water within the cabin frame, ensuring the experience and safety of the user. Compared to the prior art, the water mist simulation module 41 in this embodiment can greatly reduce, or even prevent, the water mist simulation module 41 from continuing to spray water after the water pump is turned off.

[0065]

[0066] The VR full-sensory training cabin of this embodiment is equipped with a flame simulation module 45. This module includes a water tank 451 located in the bottom 11 of the cabin. A water mist generating module 455 (ultrasonic atomizer) is installed in the water tank 451 to generate water mist. A mounting base 456 is installed at the opening of the water tank 451. An air outlet 4561 is provided on the mounting base 456. A blowing module 454 is installed above the mounting base 456 to blow air into the water tank 451, causing the water mist to diffuse outward through the air outlet 4561. A lighting module 453 is also provided on the mounting base 456 along the air outlet 4561 to illuminate the water mist and create a flame visual effect.

[0067] Furthermore, an upper cover plate 452 is provided on the top of the mounting base 456. The upper cover plate 452 has a water mist outlet 4521 and a light outlet 4522, corresponding to the emission paths of the water mist and the light, respectively. An upper water level detection element 4562 and a lower water level detection element 4563 are also provided inside the lower water tank 451 for detecting the water level. A photosensitive element 4523 is also provided on the upper surface of the upper cover plate 452.

[0068] In addition, to enhance the visual effect and reduce interference from the external environment (wind), a dark background plate 457 is provided on the outside of the flame simulation module 45. Water mist is projected onto the dark background plate 457 to form a distinct "flame" outline. The flame simulation module 45 is provided in both the left module 111 and the right module 113 of the bilge, and the dark background plate 457 is located on the side of the two flame simulation modules 45 that is far apart from each other.

[0069] Understandably, the water mist can be projected onto the dark background panel 457 to create a flame-like effect. The dark background panel contrasts strongly with the water mist and light, making the outline of the "flame" clearer, the color more vibrant, and the three-dimensionality and realism stronger. Moreover, the dark background panel 457 is located on the side where the two flame simulation modules 45 are far apart from each other, which can act as a windbreak to ensure the effect of simulating flames. Understandably, the flame simulation module 45 uses a combination of water mist and light. Specific colored lights, such as warm yellow, illuminate the water mist to create a realistic flame visual effect, avoiding the safety hazards associated with using real flames. The airflow module 454 controls the flow pattern of the water mist to simulate the dynamic effect of a flickering flame. This embodiment of the VR immersive training cabin also includes a background module 15, which is fixedly installed between the left rear column 143 and the right rear column 144, serving as the rear wall structure of the cabin. The background module 15 includes an upper background wall 151 and a lower background wall 152. A display 153 is mounted on the upper background wall 151 for playing safety training videos or virtual scene images.

[0070] Furthermore, the VR immersive training cabin also includes an injury simulation unit and a motion platform 3. The injury simulation unit includes at least one of the following: a crush simulation module 51, an electric shock simulation module 52, a gear simulation module 53, a pulley simulation module 54, and a lateral impact module 55, used to simulate different types of mechanical injury scenarios. These modules can be selectively installed at appropriate locations on the cabin frame 1 according to training needs.

[0071] The gear simulation module 53 includes a corresponding driving gear and a driven gear. The driving gear is driven to rotate by a drive motor, while the driven gear is connected to an electric push rod. The distance between the driven and driving gears is adjusted by the electric push rod to simulate different degrees of injury during gear meshing. Correspondingly, the pulley simulation module 54 includes a driving pulley and a driven pulley connected by a belt. The driving pulley is driven to rotate by a drive motor, while the driven pulley is connected to an electric push rod. The distance between the driven and driving pulleys is adjusted by the electric push rod to simulate different degrees of injury during gear meshing. The compression simulation module includes an up-and-down drive motor, a pressure detection module, and a compression plate located at the output end of the up-and-down drive motor. The up-and-down drive motor moves the compression plate up and down to compress the user's hand. Different compression intensities are controlled by the lower pressure detection module to simulate different levels of compression injury. The electric shock simulation module 52 features a metal handprint. During use, the user presses their palm onto the metal handprint, and a pulse voltage is input to the handprint to simulate electric shock.

[0072] The motion platform 3 includes a movable platform 31 and at least one second drive unit 32. The movable platform 31 is horizontally positioned above the middle module 112 of the cabin bottom and corresponds to the position of the falling object simulation experience unit. The output end of the second drive unit 32 is connected to the bottom of the movable platform 31 and is used to drive the movable platform 31 to perform multi-directional shaking, tilting, or vibration movements. The second drive unit 32 is located on the cabin bottom 11. To enhance the user experience, one second drive unit 32 is installed in each of the left module 111, the middle module 112, and the right module 113 of the cabin bottom.

[0073] When the participant is on the activity platform 31, the motion platform 3 and the falling object simulation experience unit work together. As the object falls, the activity platform 31 shakes, simulating ground vibration or a person being startled and losing balance, increasing the complexity and realism of the training, allowing the participant to experience shaking and falling objects simultaneously. The second drive unit 32 is installed inside the bottom of the cabin 11. The injury simulation unit allows trainees to personally experience various mechanical injuries (such as squeezing pressure, slight electric current, friction, etc.) through physical contact or mild stimulation, establishing an intuitive understanding of hazards while ensuring safety. Correspondingly, a lateral impact module 55 is installed on the lower background wall 152 to simulate the experience of side object impact.

[0074] The lateral impact module 55 includes a third drive component and a lateral impact plate. The third drive component is fixed to one side of the lower background wall 152, and its output end is connected to the lateral impact plate. It drives the lateral impact plate to rotate rapidly inward toward the interior of the cabin frame 1, so that the lateral impact plate impacts the user located inside the cabin frame 1. In addition, the output end of the third drive component is connected to one end of the lateral impact plate. The rotation angle of the lateral impact plate is generally no greater than 90°. After the lateral impact plate hits the user, the third drive component can drive the lateral impact plate to automatically reset.

[0075] In addition, the compression simulation module 51 and the electric shock simulation module 52 are detachably mounted on the left beam module 131, and the gear simulation module 53 and the pulley simulation module 54 are also detachably mounted on the right beam module 132, making it easy to replace different injury simulation devices according to the training content. Correspondingly, the outer sides of the extrusion simulation module 51, electric shock simulation module 52, gear simulation module 53, and pulley simulation module 54 are all equipped with identical device boxes. These device boxes have pre-installed unified system interface ports (power supply and communication interfaces). Identical mounting slots are provided on both the left beam module 131 and the right beam module 132, allowing the device boxes to be detachably installed in these slots using bolts. The extrusion simulation module 51, electric shock simulation module 52, gear simulation module 53, and pulley simulation module 54 all utilize existing technology and will not be described in detail here. Furthermore, each of these modules is equipped with a digital display and a rotary switch. The rotary switch controls the opening and closing of the module and adjusts the gear position, while the digital display shows the current gear position of the module.

[0076] In this embodiment, the VR immersive training cabin also has a simulated fire extinguisher 133 installed on the side beam 13. The simulated fire extinguisher 133 has the same shape, weight, and operation as a real fire extinguisher, but it is not filled with real extinguishing agent. Instead, it is equipped with a lighting module that works in conjunction with the photosensitive element 4523. When the trainee picks up the simulated fire extinguisher 133 and the lighting module is aimed at the flame simulation module 45, the photosensitive element 4523 senses the light from the lighting module and triggers the flame simulation module 45 to turn off or reduce its intensity, simulating a successful fire extinguishing scenario.

[0077] The simulated fire extinguisher 133, in conjunction with the photosensitive element 4523, enables real-time interaction between trainee operation and visual feedback. When a trainee correctly uses the simulated fire extinguisher 133 to aim at the "flame," the photosensitive element 4523 recognizes the light signal and extinguishes the flame simulation module 45, providing the trainee with immediate positive feedback and reinforcing the memorization of the correct fire extinguishing procedure. Furthermore, the detachable nature of each injury simulation module allows the training chamber to be flexibly configured according to specific training targets and course arrangements. For example, gear simulation module 53 and pulley simulation module 54 can be installed in training for machine operators, while crush simulation module 51 and electric shock simulation module 52 can be installed in training for construction workers. This modular and replaceable structural design greatly improves the equipment's versatility and utilization, reducing hardware investment costs for safety training in different industries.

[0078] This embodiment provides a VR immersive training cabin. When users use the VR immersive training cabin for training and learning, the falling object simulation experience unit, motion platform 3, environmental simulation unit, and injury simulation unit can be arbitrarily combined. For example, in mine collapse safety education, the falling object simulation experience unit simulates the impact of falling objects during a mine collapse, and the motion platform 3 simulates the shaking during a mine collapse. In fire safety education, the odor simulation module 44 and the flame simulation module 45 work together to simulate these visual, tactile, and environmental sensations, thereby enabling users to experience a sense of immersion in a real scene.

[0079] Furthermore, the VR immersive training cabin in this embodiment also includes a control unit. The control unit establishes communication connections with the falling object simulation unit, the environment simulation unit, the injury simulation unit, and the motion platform 3. It sends control commands and receives status feedback from each module via wired or wireless means to control different units to work collaboratively according to different training content. The VR immersive training cabin also includes a VR module, which communicates with the control unit, the falling object simulation unit, the environment simulation unit, the injury simulation unit, and the motion platform 3. The VR module is worn on the user's head to provide a first-person perspective of the virtual scene and recognize gestures. For example, while displaying a falling object scene in VR, the falling object simulation unit is triggered to release the falling object, and the environment simulation unit is simultaneously activated to create corresponding weather conditions to construct a highly realistic dangerous experience environment.

[0080] Specifically, when the VR module is working, its binocular cameras can identify position markers within the cabin frame 1 to determine the coordinates of the injury simulation unit. Using the spatial position of the VR module and the user's hand position, it calculates the distance between the hand coordinates and the physical coordinates (e.g., the physical coordinates of gear injuries) of the injury simulation unit (each mechanical injury simulation module). Therefore, when the user reaches towards the injury simulation module, before touching the actual device, the VR module displays a virtual scene. Simultaneously, the control unit activates and demonstrates the operation or shutdown of each module, allowing the viewer to experience a realistic sensation through virtual vision and real touch, achieving an immersive warning effect of "what you see is what you touch."

[0081] The scope of protection of this invention is defined only by the claims. Thanks to the teachings of this invention, those skilled in the art will readily recognize that alternative structures to the structures disclosed herein can be used as feasible alternative implementations, and that the implementations disclosed herein can be combined to produce new implementations, which also fall within the scope of the appended claims.
