[0036] like Figure 1 The diagram shows a structural schematic of an R-VR-R space station experience facility with a single-person suspension mechanism according to this invention. R-VR-R refers to virtual reality and then back to reality. The space station experience facility is used to generate a space station environment experience area. Figure 2 As shown, this is for the experiencer in Figure 1 The diagram shows a schematic of the space station experience facility. As can be seen, the R-VR-R space station experience facility with the single-person suspension mechanism of this invention includes an indoor activity area 2 for experiencing activities inside the space station module and an outdoor activity area 1 for experiencing activities outside the space station module. The indoor activity area 2 and the outdoor activity area 1 are connected end-to-end, forming a circular space station environment experience area. The indoor activity area 2 has the same decoration as the actual space station module, replicating the real space station 1:1, giving users the feeling of entering a real space station.

[0037] The circular space station experience area features a fixed circular track 3 on its ceiling. Part of the track 3 is located in the indoor activity area 2, and another part is located in the outdoor activity area 1. A space floating simulation component 4 is mounted on the circular track 3. This component includes a floating simulation trolley 400 and a suspension mechanism. The suspension mechanism includes a floating simulation part 500 and a rotary connection part 600. The floating simulation part is installed below the floating simulation trolley and is used to suspend the user.

[0038] In addition, the space station experience facility also includes a data acquisition area 6 for collecting images of participants, a spacesuit dressing area 5 for participants to put on spacesuits, and a spacesuit removal area 8 for participants to remove their spacesuits. The spacesuit dressing area 5 is located between the exit of the data acquisition area 6 and the entrance of the intravehicular activity area 2, and the spacesuit removal area 8 is located between the exit of the intravehicular activity area 2 and the exit of the space station experience facility.

[0039] The space station experimenter enters the data collection area 6 from the space station entrance 7 gate (not shown) and the data collection equipment (not shown) in the data collection area 6 collects the experimenter's data, such as the experimenter's 3D facial image, height, weight, etc. After the data collection is completed, the experimenter enters the space suit dressing area 5 to wear the space experience equipment, such as the tethered suit, to prepare for entering the space station experience area. The experimenter enters the space station experience area from the in-cabin activity area 2 entrance and uses the floating simulation travel vehicle 400 and the floating simulation component 500 in the space station experience area to perform space floating simulation actions in the in-cabin activity area 2 and the extra-cabin activity area 1, so that the experimenter enters the space floating simulation environment. After the experience is completed, the experimenter enters the space suit undressing area 8 from the in-cabin activity area 2 exit.

[0040] In addition, referring to Figure 9 , the space station experience facility further comprises: a VR helmet 10 worn on the head of the experimenter, used to display a space station virtual reality scene of space station in-cabin activities and space station extra-cabin activities; a central control room 11 used to control the space floating simulation assembly 4 to perform space floating simulation actions and control the VR helmet to display the space station virtual reality scene. After the experimenter wears the VR helmet in the in-cabin activity area 2, the space floating simulation assembly performs space floating simulation actions corresponding to the space station virtual reality scene displayed by the VR helmet, so that the experimenter enters the space station virtual reality environment and the space floating simulation environment. The space floating simulation assembly moving along the circular track 3 enters the extra-cabin activity area 1 from the in-cabin activity area 2 and returns to the in-cabin activity area 2, so that the experimenter is always immersed in the real and virtual reality space station environment during the experience process of entering the space station cabin wearing the VR helmet until taking off the VR helmet.

[0041] After the experimenter 9 enters the in-cabin activity area 2 and is hung on the floating simulation component 500, the VR helmet worn on the head of the experimenter synchronously performs space station virtual reality scenes and space floating simulation actions with the space floating simulation assembly. Specifically, the VR helmet worn on the head of the experimenter 9 displays a space station virtual reality scene of space station in-cabin activities and space station extra-cabin activities, so that the experimenter enters the space station virtual reality environment; the space floating simulation assembly simultaneously performs various space floating simulation actions corresponding to the space station virtual reality scene displayed by the VR helmet, so that the experimenter 9 enters the space floating simulation environment while entering the space station virtual reality environment.

[0042] Referring to Figure 1 and Figure 9The cabin activity area 2 is provided with a camera 12, and correspondingly, the central control room 11 (the installation position of the central control room can be determined according to actual conditions) is provided with a monitor 114 receiving a video image output by the camera, which is used for judging whether the experience person in the cabin wears a VR helmet according to an image captured by the camera, and when it is judged that all the experience persons in the cabin wear the VR helmet, the VR helmet is controlled to display a space station virtual reality scene.

[0043] The central control room is provided with a processor 113 and a VR video player 112, and correspondingly, the central control room controlling the VR helmet to display the space station virtual reality scene comprises that the VR video player arranged on the central control room transmits the VR video to the VR helmet; the VR video comprises key marks corresponding to the start and end of the space station activity scene; a key mark detection module in the processor is used for detecting the key marks in the VR video in real time, and the processor sends corresponding control instructions to the floating simulation traveling trolley and the floating simulation component according to the detected key marks, so that the floating simulation traveling trolley and the floating simulation component perform space floating simulation actions corresponding to the space station virtual activity scene displayed by the VR helmet. In order to ensure the space station experience effect of the experience person, the central control room is further provided with a transmission delay module 111, which is used for transmitting the VR data to the VR glasses or the helmet display after the corresponding control instructions are sent to the floating simulation traveling trolley 400 and the floating simulation component 500. The floating simulation traveling trolley 400 and the floating simulation component 500 are respectively provided with controllers, the controllers receive the control instructions sent by the processor of the central control room, and control the floating simulation traveling trolley and the floating simulation component to perform the space floating simulation actions according to the control instructions.

[0044] The space station experience facility is arranged on land, and after the experience person 9 enters the cabin activity area 2, the experience person can see the decoration similar to that in the real space station cabin and experience the feeling of entering the real space station. The experience person 9 wears the VR helmet in the cabin activity area 2. Then, the camera arranged in the cabin activity area 2 transmits the image of the experience person to the monitor of the central control room, so as to determine whether the experience person is securely connected to the rope and wears the VR helmet. When it is determined that all the experience persons are connected to the rope and wear the VR helmet, the central control room transmits the VR video to the VR helmet, controls the VR helmet to display the space station virtual reality scene, and sends corresponding control instructions to the floating simulation traveling trolley and the floating simulation component, so that the floating simulation traveling trolley and the floating simulation component perform the space floating simulation actions corresponding to the space station virtual activity scene displayed by the VR helmet. At this time, the experience person is immersed in the virtual reality scene of the cabin activity area 2 and the cabin activity area 1. The floating simulation traveling trolley enters the cabin activity area from the cabin activity area, and then returns to the cabin activity area, so that the experience person is always immersed in the real and virtual space station environment in the experience process of entering the space station cabin and wearing the VR until taking off the VR helmet.

[0045] It is evident that the suspension mechanism is a crucial component enabling users to experience the space station in a comprehensive manner, allowing them to perform floating simulations within the virtual reality environment of the space station.

[0046] To achieve this objective, this invention provides a single-person suspension mechanism for R-VR-R space station experiences, used to connect with a floating simulation trolley 400 that moves on a circular track 3 at the top of the space station environment experience area, such as... Figures 1-6 As shown, it includes: a floating simulation component 500 disposed below the floating simulation moving vehicle for suspending the user to achieve floating simulation movements; and a rotary connection component 600 connected to the floating simulation moving vehicle and the floating simulation component respectively, which allows the user suspended on the floating simulation component to rotate relative to the floating simulation moving vehicle; wherein, the floating simulation component includes a fixed base plate and a steel wire rope for suspending the user, and the rotary connection component includes a connecting frame for fixed connection with the fixed base plate.

[0047] This invention connects the floating simulation trolley and the floating simulation component together through a rotary connecting component. When the floating simulation trolley moves along the circular track 3 on the top of the cabin in the space station environment experience area, it can drive the floating simulation component that suspends the experiencer to move, and can make the floating simulation component rotate relative to the floating simulation trolley, so that the experiencer can realize floating simulation actions, increasing the fun and experience of the experiencer floating simulation actions in the space station virtual reality environment.

[0048] Specifically, the cross-section of the circular track of this utility model is I-shaped (e.g., Figure 2 As shown, the floating simulation trolley moves along the I-shaped track 3 under the control of the central control room. It can drive the experiencer, who is pulled by the floating simulation component connected to it through the rotary connection component, to perform the action of floating in space. In conjunction with the floating simulation component under the control of the central control room, the experiencer can be pulled by the steel wire rope of the floating simulation component to perform various space floating simulation actions, such as lifting, pitching and rotating movements, so as to make the experiencer's space station experience more perfect.

[0049] The floating simulation component is connected to the floating simulation traveling vehicle via a rotary connection component, such as... Figures 7a-8bAs shown, the rotary connection component 600 of this utility model includes: a connecting frame 601 for connecting to the floating simulation component, the length of which extends parallel to the track and is longer than the width of a person's shoulder; a hanging column 602 whose lower end is fixedly connected to the center of the connecting frame; and a rotary drive 603 connected to the frame of the hanging column and the floating simulation trolley, respectively, which, driven by a drive motor 604, causes the hanging column and the floating simulation component fixedly connected to the hanging column to rotate relative to the floating simulation trolley in a horizontal plane parallel to the track. This rotary drive can adopt a structure combining a slewing bearing and a circumferential worm gear, which can achieve multi-tooth contact, large transmission torque, and withstand large radial and axial loads as well as strong overturning moments, resulting in smooth operation. During assembly, the connecting flange 605 at the lower part of the rotary drive base is fixedly connected to the upper end of the hanging column by multiple bolts (see...). Figure 5 The top plate on the upper part of the base is fixedly connected to the connecting plate set in the center of the floating simulation moving vehicle frame by multiple bolts.

[0050] The rotating connection component allows the floating simulation component to rotate relative to the floating simulation vehicle in the horizontal plane, thereby enabling the user suspended by the floating simulation component to perform the rotational motion in the space floating simulation action, enhancing the space station experience.

[0051] Among them, such as Figures 10-15 As shown, the floating simulation component of this utility model includes: a fixed base plate disposed below and fixedly connected to the connecting frame of the rotary connecting component, with a base plate connecting seat 515 disposed at its center, and the base plate connecting seat being fixedly connected to the middle of the connecting frame by bolts; a first set of drum assemblies 514 and a second set of drum assemblies 521 mounted on the fixed base plate (see...). Figure 13 Each set of drum assemblies includes two drum assemblies, and each drum assembly has a steel wire rope 532 wound on its drum for suspending a part of the user; two reducer assemblies are set on both sides of the fixed base plate to provide driving force to the drums of the two sets of drum assemblies respectively; wherein the distance between the two drum assemblies of the first set of drum assemblies and the two drum assemblies of the second set of drum assemblies is different.

[0052] In this invention, a speed reducer assembly provides power to the drum assembly. The speed reducer assembly includes a speed reducer base 522 fixedly mounted on a fixed base plate, a speed reducer 502 fixedly mounted on the speed reducer base, and a motor 501 connected to the speed reducer. The speed reducer is a double-output shaft speed reducer with a pair of output shafts extending in opposite directions. The double output shafts of each double-output shaft speed reducer are respectively connected to two drum assemblies of a set of drum assemblies through bushings 520 and couplings 519.

[0053] The two drum assemblies in each drum assembly are symmetrically located on the left and right sides of the corresponding reducer assembly (see...). Figure 13), and the spacing between the two reel assemblies of the first group of reel assemblies and the spacing between the two reel assemblies of the second group of reel assemblies are different, as shown in Figure 13 The spacing between the two reel assemblies of the first group of reel assemblies 514 can be greater than the spacing between the two reel assemblies of the second group of reel assemblies 521, so that the spacing between the two reel assemblies located in front is smaller than the spacing between the two reel assemblies located in back along the direction in which the trolley travels, the two shoulder parts of the experimenter can be hung by the pair of reel assemblies with smaller spacing, the back or waist of the experimenter can be hung by the pair of reel assemblies with larger spacing, the human body shape is adapted, and the experimenter is hung by the steel wire ropes on the four reel assemblies at the same time, so that the experimenter is more comfortable and safe compared with three-point suspension or two-point suspension. In application, the four reel assemblies can be simultaneously or individually actuated according to actual needs, so that the experimenter can realize lifting, pitching and other actions.

[0054] The four reel assemblies of the utility model all adopt the same structure, which comprises: a reel whose rotating shaft is connected with the output shaft of the double-output-shaft speed reducer through a shaft coupling; a steel wire rope whose one end is wound on the reel and the other end is used for hanging the experimenter; and a rope pressing wheel structure 510 arranged on one side of the reel, which is used for pressing the rope pressing wheel of the steel wire rope wound on the reel to prevent the rope from being disordered. The rope pressing wheel structure can adopt the structure of the prior art, which will not be described in detail here. By winding or unwinding the steel wire rope on the reel, the distance between the experimenter hung by the other end of the steel wire rope and the reel, i.e. the distance between the experimenter and the track, can be changed. By simultaneously or individually adjusting the distance between the four steel wire ropes of the experimenter and the track, the experimenter can realize pitching and / or lifting movements.

[0055] In application, the floating simulation trolley drives the floating simulation component to move to simulate the action of floating in space, and the four reel assemblies of the floating simulation component are individually or simultaneously actuated, so that the experimenter hung by the floating simulation component can realize pitching or lifting movements, for example: the second group of reel assemblies of the floating simulation component releases the steel wire rope, and the first group of reel assemblies winds the steel wire rope, so that the experimenter hung by the floating simulation component can experience the action of diving; the second group of reel assemblies and the first group of reel assemblies of the floating simulation component synchronously wind the steel wire rope, so that the experimenter hung by the floating simulation component can experience the action of ascending, and so on. The specific action of the floating simulation component can be determined according to the need for simulating the movement of the space station, so that the experimenter hung by the lifting mechanism can realize various floating simulation actions of the space station, and the interest and interactivity are increased.

[0056] In conclusion, the single-person suspension mechanism for realizing the space station R-VR-R experience can enable the experimenter to board the real simulation space station and perform various space floating simulation actions, such as floating movement, rotation movement, lifting movement, pitching movement, etc., and under the cooperation with other mechanisms, such as wearing a VR helmet in the annular space station experience area of the simulation space station, the experimenter can be immersed in the virtual reality space station environment.

[0057] Although the utility model has been described in detail above, the utility model is not limited thereto, and those skilled in the art can make various modifications according to the principle of the utility model. Therefore, any modification made according to the principle of the utility model should be understood as falling within the protection scope of the utility model.
