Description

Technical Field

[0001] The present application relates to the field of ski simulation technology, and in particular to a ski simulation system based on VR technology. Background Art

[0002] VR technology, also known as virtual reality technology, is a new practical technology developed in the 20th century. It mainly uses computers and other equipment to create a virtual world with realistic three-dimensional visual, tactile, olfactory and other sensory experiences, so that the experiencer can have an immersive feeling.

[0003] Skiing is an recreational activity that combines entertainment and exercise, but skiing itself is highly dependent on the natural environment, and ski resorts cannot be set up in general areas; however, with the continuous development of virtual machine technology, VR ski simulators suitable for people to experience skiing indoors are gradually being introduced.

[0004] Chinese patent publication number CN110898412A discloses a VR intelligent multi-element simulated ski machine, comprising a base and ski pedals mounted on the base. A vibration device is provided between the base and the ski pedals to cause the pedals to vibrate, and a display device for playing ski scenes is provided on the base. The user wears a VR helmet and stands on the ski pedals. The simulated ski scene is played inside the VR helmet or on the display device, and the vibration device causes the ski pedals to vibrate the user, creating a realistic skiing experience.

[0005] Regarding the above-mentioned related technologies, the inventors found that: the experiencers only simulate the skiing experience by watching skiing videos and feeling the shaking of the ski pedals. The overall skiing experience mode is relatively simple, which reduces the experiencers' real experience. Summary of the Invention

[0006] In order to improve the real experience of the user, this application provides a skiing simulation system based on VR technology.

[0007] This application provides a VR-based skiing simulation system that uses the following technical solutions:

[0008] A skiing simulation system based on VR technology includes a base, a VR helmet for playing skiing videos, and a ski board arranged on the base; a sliding platform is provided between the base and the ski board, the sliding platform and the base are slidably connected, a rotating screw is rotatably provided inside the base, the rotating screw passes through the sliding platform, and the rotating screw is threadedly connected to the sliding platform, a rotating motor is provided on the base for driving the rotating screw to rotate, and a control component for controlling the rotation direction of the output end of the rotating motor is provided between the sliding platform and the ski board.

[0009] By adopting the above technical solution, the experiencer wears a VR helmet and watches a skiing video through the VR helmet; when the experiencer watches a curve segment in the skiing video, the control component controls the rotation direction of the output end of the rotating motor, so that the rotating screw rotates in different directions, thereby driving the sliding table, the skis and the experiencer to move along the length direction of the rotating screw; the two sets of directions in which the sliding table moves along the rotating screw correspond to the left and right directions of the curve segment in the skiing video, so that the experiencer and the game character in the video are synchronously offset in the curve segment, thereby improving the interaction between the experiencer and the character in the skiing video in the VR helmet, and further improving the experiencer's real skiing experience.

[0010] Preferably, the control component includes a rotating table, a lever and two micro switches; the rotating table is arranged between the sliding table and the ski board, one end of the rotating table is rotatably connected to the sliding table, and the other end of the rotating table is connected to the ski board; the two micro switches are symmetrically distributed on both sides of the rotating table, and both micro switches are electrically connected to the rotating motor, and the micro switches are used to control the rotation direction of the output end of the rotating motor; the lever is arranged on the side wall of the rotating table to contact the trigger point of the micro switch.

[0011] By adopting the above technical solution, the experiencer stands on the rotating platform with skis, and the rotating platform increases the experiencer's freedom of movement. When the experiencer watches the cornering video of the skiing video in the VR helmet, the experiencer's body can be twisted accordingly, and the rotating platform and the lever can be driven to rotate. The lever is offset against the trigger point of the micro switch to change the rotation direction of the rotating screw driven by the output end of the rotating motor, thereby adjusting the movement direction of the sliding platform along the rotating screw, and by making the movement direction of the sliding platform consistent with the offset direction of the game character's cornering in the skiing video of the VR helmet, the experiencer and the game character in the VR helmet are synchronously offset, thereby allowing the experiencer to interact with the video character in the VR helmet and improving the experiencer's real skiing experience.

[0012] Preferably, two sets of limiting rods are provided on the side wall of the sliding platform close to the rotating platform, and the two limiting rods are symmetrically distributed on both sides of the shifting rod.

[0013] By adopting the above technical solution, the limit rods symmetrically distributed on both sides of the lever limit the rotation direction of the lever, reducing the phenomenon of the experiencer driving the turntable to excessive rotation; the lever and the limit rods are offset against each other, and at the same time, the lever and the trigger point of the micro switch are offset against each other, reducing the excessive rotation of the lever and the phenomenon of the lever and the trigger point of the micro switch colliding violently, thereby ensuring the service life of the micro switch.

[0014] Preferably, a plurality of balls are rotatably provided on the side wall of the sliding platform close to the rotating platform, and all of the balls are against the rotating platform.

[0015] By adopting the above technical solution, the ball bearings fill the gap between the sliding table and the rotating table, and the ball bearings support the rotating table, thereby reducing the possibility of the rotating table tilting when the user stands on the rotating table, which may cause the connection between the rotating table and the sliding table to break, thereby improving the stability of the rotating table. In addition, the rotating ball bearings do not significantly increase the friction resistance between the sliding table and the rotating table, thereby ensuring the convenient rotation of the rotating table relative to the sliding table.

[0016] Preferably, a rotating notch is provided on the side wall of the rotating platform close to the ski board, a mounting plate connected to the ski board is rotatably arranged inside the rotating notch, and a driving component for driving the mounting plate to rotate is arranged inside the rotating notch.

[0017] By adopting the above technical solution, the driving component drives the mounting plate to rotate the skis, so that the user on the skis is affected by the up and down swinging force of the mounting plate. Through the cooperation of the VR helmet, the user can interact with the bumpy feeling during the skiing video in the VR helmet, further improving the realism of the user's simulated skiing.

[0018] Preferably, the driving assembly includes two sets of gear plates, a rotating shaft, two sets of transmission gears and a driving member; the two gears are symmetrically distributed on both sides of the mounting plate, and each of the gear plates is located inside the rotating notch; the rotating shaft is rotatably arranged on the inner wall of the rotating notch, and the two transmission gears are both sleeved on the rotating shaft, the gear plates and the transmission gears correspond one to one, and each of the transmission gears is engaged with the corresponding gear plate, and the driving member is used to drive the rotating shaft to rotate.

[0019] By adopting the above technical solution, the driving member drives the rotating shaft to rotate, the rotating shaft drives the transmission gear to rotate, and the transmission gear and the gear plate engage with each other to drive the gear plate to drive the mounting plate to rotate, so that the mounting plate drives the ski board and the experiencer to swing up and down, thereby increasing the experiencer's skiing authenticity.

[0020] Preferably, the snowboard includes a slide plate, a pedal and a stabilizing spring; the slide plate is arranged on the side wall of the rotating platform away from the sliding platform, and a mounting groove for the pedal to be inserted into is provided on the slide plate, the pedal is rotatably arranged on the inner side wall of the mounting groove, and the stabilizing spring is arranged between the pedal and the inner side wall of the mounting groove.

[0021] By adopting the above technical solution, the experiencer steps on the pedal, and the stabilizing spring supports the pedal. At the same time, the stabilizing spring generates elastic force through its own expansion and contraction to prevent the pedal from rotating, thereby ensuring the stability of the experiencer standing on the rotatable pedal; in addition, the experiencer can make the pedal rotate slightly by leaning the body and stepping hard, so as to cooperate with the sliding platform to move along the length direction of the rotating screw; the slight rotation of the pedal further improves the experiencer's freedom of movement, and allows the experiencer to tilt slightly synchronously with the skiing scene in the VR helmet, thereby improving the experiencer's sense of reality of simulated skiing; at the same time, the rotating pedal ensures the experiencer's ankle mobility, reduces the occurrence of the experiencer spraining his ankle when the sliding platform drives the experiencer to move, thereby improving the experiencer's safety when using the ski simulation system.

[0022] Preferably, a plurality of positioning rods are provided on the inner side wall of the mounting groove, and all the positioning rods are symmetrically distributed on both sides of the pedal.

[0023] By adopting the above technical solution, the rotating pedal counteracts the positioning rod, limiting the rotation angle of the pedal and reducing the phenomenon that the experiencer turns the pedal too much, causing the experiencer to tilt too much and fall, thereby ensuring the safety of the experiencer when using the ski simulation system.

[0024] Preferably, guardrails are provided on both sides of the base, each guardrail is provided with a plurality of groups of railings, and each railing is provided with a buffer pad.

[0025] By adopting the above technical solution, the guardrail can be used to support the experiencer while moving on the sliding platform, reducing the occurrence of falls by the experiencer while sliding along the sliding platform; in addition, the soft cushion reduces the violent collision between the experiencer and the railing, reducing the phenomenon of the experiencer being injured by hitting the railing, and further improving the safety of the experiencer when using the ski simulation system.

[0026] Preferably, a handrail sliding sleeve is slidably provided on each of the guardrails, and an anti-fall vest is provided on one group of the handrail sliding sleeves.

[0027] By adopting the above technical solution, the experiencer can support the handrail sliding sleeves with both hands while sliding on the sliding platform, and the handrail sliding sleeves follow the experiencer to slide synchronously along the length of the guardrail. On the one hand, the sliding handrail sliding sleeves ensure the normal sliding of the experiencer on the sliding platform; on the other hand, the sliding handrail sliding sleeves can continuously provide support for the experiencer, reducing the phenomenon of the experiencer falling during the use of the ski simulation system, and improving the experiencer's safety; in addition, during the experiencer's movement, the experiencer can wear an anti-fall vest on his body, and the anti-fall vest follows the experiencer through the handrail sliding sleeves to ensure the experiencer's normal movement. The anti-fall vest supports the experiencer's body, reducing the phenomenon of the experiencer accidentally falling onto the base and getting injured, and further improving the experiencer's safety during the use of the ski simulation system.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By setting a control component to control the output end of the rotating motor to drive the rotation direction of the rotating screw, the experiencer can twist according to the skiing video in the VR helmet to drive the rotating table and the lever to rotate. The lever hits the trigger point of different micro switches, so that the sliding table drives the experiencer to move along the length of the rotating screw. The movement direction of the experiencer driven by the sliding table is consistent with the offset direction of the game character in the VR helmet, allowing the experiencer to interact with the character in the VR helmet, giving the experiencer a real skiing experience, thereby improving the experiencer's skiing realism;

[0030] 2. By setting up a drive component to control the mounting plate to swing up and down, the mounting plate drives the skis and the user to move up and down. Combined with the skiing video of the game character in the VR helmet, this creates a real skiing bumpy feeling for the user, thereby enhancing the authenticity of the skiing experience.

[0031] 3. By providing a rotational connection between the pedals and the slide, and by providing a stabilizing spring to increase the stability of the user's foot on the pedals and the resistance to pedal rotation, the user can achieve a slight tilt of the body by rotating the pedals, further improving the user's freedom of movement and creating a sense of tilt at different distances during the user's real skiing process. At the same time, the slightly rotating pedals reduce the possibility of users spraining their ankles while following the movement of the sliding platform, thereby improving the safety of users when using the ski simulation system.

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1-6 This application is described in further detail.

[0041] The embodiment of the present application discloses a skiing simulation system based on VR technology, which is used to reflect the real experience of the user.

[0042] Reference Figure 1 and Figure 2 A skiing simulation system based on VR technology includes a base 1 placed on the ground, a VR helmet for playing skiing videos, and a snowboard 2 mounted on the base 1. A rotating screw 11 is rotatably connected to the base 1 through a bearing, and the length direction of the rotating screw 11 is parallel to the length direction of the base 1. A sliding platform 3 is slidably connected to the upper surface of the base 1 along the length direction, and the snowboard 2 is mounted on the sliding platform 3. Several groups of rollers 30 are rotatably mounted on the side wall of the sliding platform 3 near the base 1. All the rollers 30 are symmetrically distributed on both sides of the rotating screw 11, and each group of rollers 30 is against the upper surface of the base 1, so that the sliding platform 3 can rotate along the length direction of the base 1.

[0043] Reference Figure 1 and Figure 3 A rotating screw 11 extends through the sliding platform 3 and is threadedly connected to the sliding platform 3. A rotating motor 12 is mounted at one longitudinal end of the base 1. The output end of the rotating motor 12 is in driving connection with one end of the rotating screw 11, thereby driving the rotating screw 11 to rotate. A control assembly 4 is mounted between the sliding platform 3 and the skis 2 to control the rotation direction of the output end of the rotating motor 12, thereby regulating the sliding direction of the sliding platform 3.

[0044] Reference Figure 1 and Figure 2 Guardrails 13 are welded and fixed on both sides of the base 1 in the width direction, and the guardrails 13 extend along the length of the base 1. Several sets of railings 131 are welded and fixed to each guardrail 13, and all railings 131 are spaced apart along the length of the guardrail 13. All guardrails 13 are arranged in the vertical direction, and each guardrail 13 is sleeved with a cushioning pad 1311. In this embodiment, the cushioning pad 1311 can be made of rubber to reduce the impact damage between the user and the railing 131.

[0045] Reference Figure 1 and Figure 2 Both sets of guardrails 13 are sleeved with handrail sleeves 132. In this embodiment, the handrail sleeves 132 can be made of hard plastic. Each set of handrail sleeves 132 can slide relative to the guardrails 13, and one set of handrail sleeves 132 is fixedly connected to an anti-fall vest 1321 via a cloth strap for the user to wear. When the user stands on the ski board 2 and moves along the sliding platform 3, the user's hands support the handrail sleeves 132, and the user wears the anti-fall vest 1321, thereby reducing the possibility of the user falling during the simulated skiing.

[0046] Reference Figure 2 and Figure 3 The control assembly 4 includes a rotating platform 41, a lever 42, and two micro switches 43. A rotating groove 31 is defined on the side wall of the sliding platform 3 near the ski 2. The rotating platform 41 is rotatably connected to the inner wall of the rotating groove 31 via a bearing. The side wall of the rotating platform 41 away from the base 1 is connected to the ski 2.

[0047] Reference Figure 2 and Figure 3 Several groups of balls 33 are embedded in the inner wall of the rotating groove 31. All the balls 33 are rotatably connected to the inner wall of the rotating groove 31, and each ball 33 is against the side wall of the rotating platform 41 close to the base 1 to support the rotating platform 41.

[0048] Reference Figure 2 and Figure 4The lever 42 is welded to the side wall of the rotating platform 41 and is located inside the rotating groove 31. Two sets of limit rods 32 are welded to the inner wall of the rotating groove 31, symmetrically located on either side of the lever 42. The limit rods 32 abut against the lever 42 to limit the rotation angle of the lever 42 and the rotating platform 41.

[0049] Reference Figure 1 and Figure 3 Two sets of micro switches 43 are fixedly connected to the inner wall of the rotating groove 31 via screws, and each set of micro switches 43 is electrically connected to the rotating motor 12. In this embodiment, the rotation direction of the output end of the rotating motor 12 is controlled by contacting the trigger points of the micro switches 43. The two sets of micro switches 43 are symmetrically distributed on either side of the lever 42, which is located between the two sets of micro switches 43. When the lever 42 contacts the limit rod 32, the lever 42 contacts the trigger points of the micro switches 43, thereby quickly controlling the rotation direction of the output end of the rotating motor 12.

[0050] Reference Figure 2 and Figure 3 In this embodiment, the VR helmet is electrically connected to micro switches 43. The two sets of micro switches 43 correspond one-to-one with the left and right movement directions of the game character in the VR helmet skiing video. Furthermore, the micro switches 43 control the movement direction of the sliding platform 3 to align with the offset direction of the game character when cornering in the VR helmet skiing video. While the VR helmet is playing the skiing video, the user's body drives the rotating platform 41 and the lever 42 to rotate, and the lever 42 contacts the two sets of micro switches 43, thereby controlling the real-time movement direction of the game character in the VR helmet skiing video. The offset direction of the game character when cornering in the VR helmet skiing video is aligned with the movement direction of the user driven by the sliding platform 3, allowing the user to simulate the scene in the skiing video in real time, thereby enhancing the user's skiing experience.

[0051] Reference Figure 3 and Figure 5 The side wall of the rotating platform 41 away from the base 1 has a rotation notch 411 formed along the thickness direction. A mounting plate 412 is rotatably connected to the rotation notch 411 via a rotating shaft. The side wall of the mounting plate 412 away from the base 1 is connected to the snowboard 2. A driving assembly 5 is installed inside the rotation notch 411 to drive the mounting plate 412 to rotate the snowboard 2.

[0052] Reference Figure 5 and Figure 6The drive assembly 5 includes two sets of gear plates 51, a rotating shaft 52, two sets of transmission gears 53, and a driving member 54. The two sets of gear plates 51 are symmetrically distributed on both sides of the width direction of the mounting plate 412. The width direction of the mounting plate 412 is parallel to the length direction of the rotating screw 11. The two sets of gear plates 51 are integrally formed on the side wall of the mounting plate 412 near the base 1.

[0053] Reference Figure 2 and Figure 5 The rotating shaft 52 is rotatably connected to the sidewall of the rotating notch 411 via a bearing, with the length of the rotating shaft 52 parallel to the width of the mounting plate 412. Two sets of transmission gears 53 are fixedly sleeved on the rotating shaft 52, with one set of transmission gears 53 located at one end of the rotating shaft 52 and the other set of transmission gears 53 symmetrically located at the other end. The transmission gears 53 correspond one-to-one with the gear plates 51, and the transmission gears 53 mesh with the corresponding gear plates 51.

[0054] Reference Figure 2 and Figure 5 The driving member 54 includes a driving motor 541 and a gear set 542. The driving motor 541 is fixedly mounted on the inner side wall of the rotating notch 411 by screws, and the gear set 542 is fixedly mounted on the output end of the driving motor 541 and the rotating shaft 52. When the output end of the driving motor 541 rotates, the gear set 542 meshes with the rotating shaft 52, thereby driving the rotating shaft 52 to rotate. In this way, the transmission gear 53 of the rotating shaft 52 drives the gear plate 51 and the mounting plate 412 to rotate.

[0055] Reference Figure 3 and Figure 5 The snowboard 2 includes a slide plate 21, a pedal 22, and a stabilizing spring 23. The slide plate 21 is fixedly attached to the side wall of the mounting plate 412 away from the base 1 by screws, with the length of the slide plate 21 parallel to the length of the mounting plate 412. The side wall of the slide plate 21 away from the mounting plate 412 defines a mounting slot 211, and the pedal 22 is rotatably connected to the inner side wall of the mounting slot 211 via a rotating shaft.

[0056] Reference Figure 3 and Figure 5 The stabilizing spring 23 is evenly distributed between the pedal 22 and the slide 21. One end of the stabilizing spring 23 is adhesively connected to the pedal 22, and the other end is adhesively connected to the slide 21. The expansion and contraction direction of the stabilizing spring 23 is parallel to the vertical direction. The elastic force of the stabilizing spring 23 during expansion and contraction slows down the rotation speed of the pedal 22.

[0057] Reference Figure 3 and Figure 5A plurality of positioning rods 212 are glued to the inner sidewalls of the mounting groove 211, and all the positioning rods 212 are symmetrically distributed on both sides of the width direction of the pedal 22. When the pedal 22 rotates relative to the slide plate 21, the pedal 22 can abut against the positioning rods 212 to limit the rotation angle of the pedal 22.

[0058] The implementation principle of a skiing simulation system based on VR technology in this application embodiment is as follows:

[0059] The experiencer places his feet on the pedals 22 and his hands on the handrail slide 132 without the anti-fall vest 1321 installed. He puts the anti-fall vest 1321 on the experiencer's body and puts the corresponding VR helmet on the experiencer's head to play skiing videos on the experiencer.

[0060] When the user watches a turn in a skiing video on a VR headset, they twist their body, driving the rotating platform 41 to rotate the lever 42. The lever 42 contacts the trigger point of the micro switch 43, changing the direction of rotation of the output end of the rotating motor 12 and driving the rotating screw 11 to rotate in a different direction, thereby driving the sliding platform 3 to move the snowboard 2 and the user along the length of the base 1.

[0061] By driving the experiencer to move along the base 1 in the same direction as the offset direction of the game character in the VR helmet when turning, the experiencer can interact with the skiing video of the game character in the VR helmet, thereby improving the experiencer's real skiing experience.

[0062] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
