[0033] The utility model discloses the space station experience facility of simulation sets up on land, after the experimenter 9 enters the cabin activity area 2, can see similar to the decoration in the real space station cabin, experiences the feeling of entering the real space station. The experimenter 9 wears VR helmet in the cabin activity area 2.

[0034] It can be seen that the floating simulation action of the experimenter in the space station virtual reality environment can be safely performed, which is an important part of realizing the above-mentioned purpose, in order to realize the above-mentioned purpose, the utility model provides a kind of safety device for R-VR-R space station experience, it includes: the floating simulation component 500 for being connected with the floating simulation travel trolley 400 installed on the annular track in the top of space station environment experience area cabin, with fixed bottom plate 503 for being connected with floating simulation travel trolley and steel wire rope 532 for suspending experimenter;With fixed bottom plate connection is used to ensure that the safety mechanism of steel wire rope suspension is realized safe floating simulation action of experimenter.
[0035] Specifically, as shown in Figures 4-9 The utility model floating simulation component 500 includes: fixed bottom plate 503 fixedly connected with car frame;First group of reel assembly 514 and second group of reel assembly 521 (see Figure 7 ) are arranged on the front and back sides of fixed bottom plate, each reel assembly includes two reel assemblies, and steel wire rope 532 for suspending experimenter is wound on the reel of each reel assembly;Two speed reducer assembly for providing driving force for the reels of two reel assemblies are arranged on both sides of fixed bottom plate.
[0036] Fixed bottom plate 503 is connected with the bottom of the car frame of floating simulation travel trolley, when connecting, the two can be directly fixedly connected, also can be connected through intermediate mechanism, when manufacturing, bottom plate connecting seat 515 is arranged at the center position of fixed bottom plate, correspondingly, connecting plate (not shown in the figure) for being connected with bottom plate connecting seat can be arranged at the center of the car frame of floating simulation travel trolley.
[0037] The utility model provides power for reel assembly through speed reducer assembly, and it includes speed reducer base 522 fixedly installed on fixed bottom plate, speed reducer 502 fixedly installed on speed reducer base, motor 501 connected with speed reducer, and the speed reducer is a double-output-shaft speed reducer with a pair of output shafts extending in opposite directions, and the double-output-shaft speed reducer is drivingly connected with two reel assemblies of a reel assembly through shaft sleeve 520 and coupling 519.
[0038] Each reel assembly of each reel assembly is symmetrically located on the left and right sides of corresponding speed reducer assembly (see Figure 7 ), and the spacing between the two reel assemblies of the first reel assembly is different from the spacing between the two reel assemblies of the second reel assembly. Figure 7As shown, the structure that the distance between two reel assemblies of the first group 514 is greater than the distance between two reel assemblies of the second group 521 can be adopted, so that the distance between two reel assemblies in front is smaller than the distance between two reel assemblies in back along the direction of the trolley, the double shoulder of the experimenter is hung by the pair of reel assemblies with smaller distance, the back or waist of the experimenter is hung by the pair of reel assemblies with larger distance, the human body shape is adapted, and the experimenter is hung by four reel assemblies simultaneously, compared with three-point suspension or two-point suspension, the experimenter hung by four-point suspension of the utility model is more comfortable and safe.
[0039] 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 a double-output shaft speed reducer through a shaft coupling; a steel wire rope which is wound on the reel at one end and is used for suspending the experimenter at the other end; and a rope pressing wheel structure 510 arranged on one side of the reel, which is used for pressing the steel wire rope wound on the reel to prevent the rope from being disordered, and the rope pressing wheel structure can adopt the structure of the prior art, which will not be described in detail here.
[0040] During the motion experience, four hanging points are arranged on the experimenter, wherein every two hanging points are connected with two steel wire ropes on a group of reel assemblies, that is, one motor speed reducer of each group of reel assemblies is connected with two reels of wound steel wire ropes simultaneously. When the motor works, two steel wire ropes are wound or unwound through the rotation of two reels driven by the motor, so that the experimenter is driven to realize the simulation action through four steel wire ropes of two groups of reel assemblies. The floating simulation trolley moves on the ring track 3 under the control of the central control room, can drive the experimenter connected with the floating simulation component 500 to perform the action of space floating walking, and cooperates with the floating simulation component 500 under the control of the central control room, can perform various space floating simulation actions such as floating motion, lifting motion, pitching motion and the like through the steel wire rope of the floating simulation component 500 to pull the experimenter.
[0041] In order to ensure that the experimenter suspended by the steel wire rope is safer during the safe floating simulation action in the space station experience, the utility model further arranges a safety mechanism connected with the fixed bottom plate on the floating simulation component.
[0042] As Figures 5-7As shown, the safety mechanism includes a steel wire rope safety block 533 arranged on the steel wire rope for limiting the upper limit position of the experimenter in suspension.
[0043] Specifically, four through holes are arranged at the four corners of the fixed base plate (e.g. near the winding drum position), and four through holes are also arranged at the corresponding four corners of the horizontal anti-collision plate with a size similar to that of the fixed base plate. The anti-collision plate below the fixed base plate is connected with the fixed base plate through four connecting members such as bolts with an outer diameter smaller than the diameter of the through holes, so that the anti-collision plate can be inclined relative to the fixed base plate and have a certain gap therebetween. In addition, other ways of existing technology can also be used to hinge the two together.
[0044] Four travel switch supports 528 are arranged at the four corners of the fixed base plate, and one travel switch 505 is installed on each travel switch support. When assembled, the travel switch is installed on the outside of the corresponding winding drum and protrudes from the fixed base plate. Correspondingly, four contact irons 531 for cooperating with the four travel switches are fixed at the corresponding positions of the four corners of the anti-collision plate through supports.
[0045] When the four steel wire ropes suspend the experimenter to perform simulation motion experience, especially when the experimenter rises to the preset limit position of the steel wire rope under the action of the steel wire rope suspension, the contact iron on the steel wire rope will collide with the anti-collision plate to cause the anti-collision plate to tilt, which will cause the contact iron installed on the anti-collision plate to collide with the travel switch corresponding in position on the fixed base plate, so that the control system of the experience facility will give a collision-related signal, and the experience facility will automatically cut off the circuit to protect the experimenter.
[0046] Further, an alarm component capable of emitting sound and / or light signals is further included, which is used to emit an alarm signal after the control system gives a collision-related signal, reminding the management personnel to handle in time. The alarm component can adopt the structure of existing technology, which will not be described in detail here.
[0047] In summary, the safety device for realizing the R-VR-R experience of the space station of the utility model can make the experimenter board the real simulation space station, cooperate with other mechanisms, such as wearing a VR helmet in the ring-shaped space station experience area of the simulation space station, so that the experimenter can be immersed in the virtual reality space station environment, and the personal safety is ensured during the experience.
[0048] Although the utility model has been described in detail above, the utility model is not limited thereto, and the person 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.
