Description

Technical Field

[0001] This utility model relates to the field of virtual reality somatosensory interactive devices, specifically to a VR dynamic swing device. Background Technology

[0002] The VR motion swing device combines virtual reality (VR) technology with a motion platform to provide users with an immersive experience by simulating real movement. Its core function is to synchronize VR content with the physical movement of the swing, enhancing the user's sensory experience.

[0003] However, existing VR motion swing devices suffer from a large number of intermediate transmission components between the drive mechanism and the swing arm, which affects the response speed, causes delays, and impacts the user's sensory experience.

[0004] Furthermore, existing VR motion swing devices are limited by mechanical structure and safety considerations, resulting in a limited range of physical movement that makes it difficult to fully simulate complex movements in VR, thus affecting the sense of immersion. In addition, existing equipment is expensive and complex to maintain, limiting its widespread adoption. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention proposes a VR dynamic swing device that can respond quickly, reduce latency, and achieve large swings to adapt to the complex motion content of VR. It is also easy to maintain and has few vulnerable parts.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A VR motion swing device includes:

[0008] The support frame includes a first bracket and a second bracket arranged opposite to each other on the left and right sides, and a rotating shaft is rotatably connected to the first bracket and the second bracket at a relative position.

[0009] A drive mechanism is provided, wherein the drive mechanism is hinged to a connecting rod via a lead screw and drives the connecting rod to rotate, and the connecting rod is fixedly connected to a rotating shaft.

[0010] A rotating frame with a seat, the rotating frame including left and right swing arms, a connecting fastener between the left and right swing arms, and the seat fixed to the connecting fastener;

[0011] The left and right swing arms have opposite first fixed points, which are respectively fixedly connected to the rotating shaft.

[0012] Preferably, the connecting rod has a second fixing point and a third fixing point, the second fixing point being fixedly connected to the rotating shaft, and the third fixing point being hinged to the lead screw.

[0013] Preferably, the second fixing point and the third fixing point are located at both ends of the connecting rod.

[0014] Preferably, the first fixing point is located in a direction away from the seat.

[0015] Preferably, the driving mechanism is a servo electric cylinder, which includes a motor and a lead screw.

[0016] Preferably, the center of gravity of the swing arm is set at a distance of 1.3 ± 0.1 m from the rotation axis, and the angle formed by the swing arm and the connecting rod is an obtuse angle.

[0017] Preferably, the rotating frame further includes a special effects pressure bar assembly, which includes a pressure bar and a special effects control box. The pressure bar is located in front of the seat, and the special effects control box is equipped with dynamic effects and shooting buttons on its top.

[0018] Preferably, it also includes a soundproof cover, which covers the servo motor.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] The VR dynamic swing device provided by this utility model uses a drive mechanism that hinges a lead screw to a connecting rod, driving the connecting rod to rotate. This direct mechanical connection reduces the number of intermediate transmission components. Fewer transmission components mean a shorter power transmission path, thus reducing energy loss and signal delay during signal transmission. When the user performs actions in the VR scene, the drive mechanism can respond quickly and drive the connecting rod to rotate, which in turn drives the rotating shaft to rotate, enabling the rotating frame and seat to quickly perform corresponding actions, achieving rapid response and reducing the impact of latency on the user experience.

[0021] Furthermore, the left and right swing arms are fixedly connected to the rotating shaft via the first fixed point, ensuring a rigid connection between the rotating shaft and the rotating frame. This rigid connection allows the rotating shaft to transmit power more stably, avoiding power transmission delays caused by loose connections or elastic deformation. When the drive mechanism drives the rotating shaft to rotate, the rotating frame can follow the movement of the rotating shaft promptly and accurately, improving the system's response speed. Moreover, since only a connecting rod is provided between the drive mechanism and the rotating shaft, compared to the drive mechanism of existing swing devices, it has fewer vulnerable parts and is easier to maintain.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," and "fourth," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] See Figures 1 to 3 This utility model discloses a VR dynamic swing device, comprising: a support frame 1, including a first support 11 and a second support 12 arranged opposite to each other, with a rotating shaft 23 rotatably connected to the first support 11 and the second support 12 at opposite positions; a drive mechanism 2, which is hinged to a connecting rod 22 via a lead screw 212 and drives the connecting rod 22 to rotate, the connecting rod 22 being fixedly connected to the rotating shaft 23; and a rotating frame 3 with a seat 33, the rotating frame 3 including left and right swing arms 31, with a connecting fastener 32 between the left and right swing arms 31, the seat 33 being fixed to the connecting fastener 32; the left and right swing arms 31 having opposite first fixing points 311, the first fixing points 311 being fixedly connected to the rotating shaft 23 respectively.

[0035] In this embodiment, the drive mechanism is hinged to the connecting rod 22 via a lead screw 212, driving the connecting rod 22 to rotate. This direct mechanical connection reduces the number of intermediate transmission components. Fewer transmission components mean a shorter power transmission path, and consequently, less energy loss and signal delay during signal transmission. When the user performs actions in the VR scene, the drive mechanism 2 can respond quickly and drive the connecting rod 22 to rotate, which in turn drives the rotating shaft 23 to rotate, enabling the rotating frame 3 and the seat 33 to quickly perform corresponding actions, achieving rapid response and reducing the impact of latency on the user experience.

[0036] Furthermore, the left and right swing arms 31 are fixedly connected to the rotating shaft 23 via the first fixed point 311. This fixed connection ensures a rigid connection between the rotating shaft 23 and the rotating frame. This rigid connection allows the rotating shaft to transmit power more stably, avoiding power transmission delays caused by loose connections or elastic deformation. When the drive mechanism drives the rotating shaft to rotate, the rotating frame 3 can follow the movement of the rotating shaft promptly and accurately, improving the system's response speed. For example, during rapid turning movements in a VR scene, the rotating shaft 23 can quickly transmit power to the rotating frame 3, enabling the seat 33 to turn quickly and reducing the impact of delays on user operation. Moreover, only a connecting rod 22 is provided between the drive mechanism 2 and the rotating shaft 23. Compared to the drive mechanism of existing swing devices, it has fewer vulnerable parts and is easier to maintain.

[0037] Furthermore, the connecting rod 22 has a second fixed point 221 and a third fixed point 222. The second fixed point 221 is fixedly connected to the rotating shaft 23, and the third fixed point 222 is hinged to the lead screw 221.

[0038] In this embodiment, the second fixed point 221 on the connecting rod 22 is fixedly connected to the rotating shaft 23, and the third fixed point 222 is hinged to the lead screw 221. This connection method allows the power of the lead screw 221 to be directly transmitted to the rotating shaft 23. The linear motion of the lead screw 212 is converted into the rotation of the rotating shaft 23 through the connecting rod 22, reducing intermediate links in the power transmission process. The directness of power transmission improves the system's response speed. When the lead screw 212 moves, it can quickly drive the connecting rod 22 to rotate, thereby driving the rotating shaft 23 to rotate, enabling the rotating frame 3 and the seat 33 to make corresponding movements in a timely manner, reducing the impact of latency on user experience. For example, in a VR scenario, the user's action commands are quickly transmitted to the rotating shaft 23 through the movement of the lead screw 212, causing the seat 33 to react quickly, enhancing the real-time nature of the interaction.

[0039] Furthermore, the second fixing point 221 and the third fixing point 222 are located at both ends of the connecting rod 22, respectively. The second fixing point 221 is fixedly connected to the upper end of the lead screw 212, and the third fixing point 222 is fixed on the rotating shaft 23, which passes through the through holes on the left and right sides of the other end of the connecting rod 22 (not shown in the figure).

[0040] In this embodiment, the third fixed point 222 is fixed on the rotating shaft 23, and the rotating shaft 23 passes through the through holes on the left and right sides of the other end of the connecting rod 22, providing a stable support point for the connecting rod 22. This design allows the connecting rod 22 to rotate smoothly around the rotating shaft 23 during movement, effectively preventing the connecting rod from shaking, shifting, or twisting when it is subjected to force, thus ensuring the stability and reliability of the entire mechanism.

[0041] Furthermore, the first fixing point 311 is located away from the seat 33. Since the first fixing point 311 is away from the seat 33, the swing arm 31 is less restricted when swinging, allowing the seat 33 to have a larger swing space, and the user can obtain a larger swing amplitude, increasing the fun and excitement of the game.

[0042] Furthermore, the drive mechanism 2 is a servo electric cylinder 21, which includes a motor 211 and a lead screw 212.

[0043] It should be noted that the VR dynamic swing device provided by this utility model also includes an electronic control system (not shown in the figure) for automatically controlling the servo electric cylinder 21.

[0044] In this embodiment, a servo electric cylinder 21 is used as the power drive source. The servo motor 211 has good dynamic performance and can quickly respond to changes in control signals to achieve rapid acceleration and deceleration. Simultaneously, the servo motor 211 has high torque control precision, allowing it to adjust the output torque promptly according to load changes, ensuring the electric cylinder maintains stable operating speed and positional accuracy under different working conditions, thereby reducing system response delay. The lead screw 212 has a high-precision thread structure (not shown in the figure), which can accurately convert the rotational motion of the servo motor 211 into linear motion. During transmission, the clearance between the lead screw 212 and the nut (not shown in the figure) is small, enabling precise position control and avoiding system delays caused by transmission errors. Therefore, this embodiment uses the servo electric cylinder 21, which can respond quickly and reduce delay impact. Furthermore, in this embodiment, when the servo electric cylinder 21 is activated, the servo motor 211 drives the lead screw 212 to extend and retract vertically, thereby driving the connecting rod 22 to rotate vertically, which in turn drives the rotating shaft 23 to rotate relative to the support frame 1. This allows for large-amplitude swinging of the rotating frame 3 to adapt to complex movements in the VR headset 5.

[0045] Furthermore, the first support 11 and the second support 12 have the same structure and are mirror images of each other. The first support 11 and the second support 12 are fixed on the ground or other supporting foundations respectively. Both the first support 11 and the second support 12 are equipped with a drive mechanism 2. The top ends of the first support 11 and the second support 12 are respectively connected to a top beam frame 13, and two rotating shafts 23 are respectively rotatably connected to the top beam frame 13.

[0046] In this embodiment, by providing a drive mechanism 2 on both the first support 11 and the second support 12, a symmetrical drive is formed, which enables the swing arm 3 to swing smoothly and in a coordinated manner.

[0047] Furthermore, first fixing plates 131 are provided on the left and right sides of the top beam frame 13. Bearings are fixed on the first fixing plates 131. Both ends of the rotating shaft 23 are respectively sleeved and fixed in the bearings, thereby realizing the rotatable connection between the rotating shaft 23 and the top beam frame 13. Specifically, an opening 1311 is provided on the first fixing plate 131. Bearing seats 1313 are respectively provided on the two outer sides of the opening 1311. Bearings (not shown in the figure) are fixedly installed in the bearing seats 1313. Both ends of the rotating shaft 23 are respectively sleeved and fixed in the bearings. Thus, when the lead screw 212 extends and retracts, driving the connecting rod 22 to rotate up and down, it drives the rotating shaft 23 to rotate in the bearings, thereby realizing the large-angle rotation of the rotating shaft 23 relative to the top beam frame 13.

[0048] Furthermore, the top ends of the left and right swing arms 31 are respectively fixed on two rotating shafts 23. The top end of the swing arm 31 passes through the opening 1311, and the hole at the top end is fitted and fixed on the rotating shaft 23. In this embodiment, the hole at the top end of the swing arm 31 is the first fixed point 311. Thus, when the rotating shaft 23 rotates at a large angle relative to the top beam frame 13, the swing arm 31 can swing around the rotating shaft 23 as the center.

[0049] In this embodiment, by providing a bearing seat 1313 on the first fixed plate 131 and fixing both ends of the rotating shaft 23 in the bearing, the stability of the swing arm 31 during rotation can be ensured. The bearing can bear the weight of the swing arm 31 and its load, and allow it to rotate smoothly, thus improving the load-bearing capacity of the entire structure.

[0050] Furthermore, a notch 1312 is provided on the outside of the opening 1311. The notch 1312 is located below the connecting rod 22. The width of the notch 1312 is larger than the width of the connecting rod 22, so that when the lead screw 212 extends or retracts, it can drive the connecting rod 22 to rotate up and down in the notch 1312.

[0051] In this embodiment, since the width of the notch 1312 is greater than that of the connecting rod 22, the connecting rod 22 has a certain vertical rotation space within the notch 1312. This design allows the connecting rod 22 to rotate more flexibly under the drive of the lead screw 212, thereby improving the flexibility of the entire mechanism. Furthermore, the design of the notch 1312 avoids interference between the connecting rod 22 and other components during rotation, thus ensuring the stable operation of the mechanism.

[0052] Furthermore, the rotating frame 3 also includes a special effects pressure bar assembly 34, which includes a pressure bar 341 and a special effects control box 342. The pressure bar 341 is located in front of the seat 33, providing an armrest and pressing down on the user's thigh to improve safety. The special effects control box 342 is equipped with dynamic effects and shooting buttons (not shown in the figure) on its top, thereby providing various dynamic effects and shooting button interactions.

[0053] Furthermore, it also includes a soundproof cover 4, which covers the servo motor 211 to reduce the noise of the servo motor 211 during operation and improve the comfort of the user experience.

[0054] Furthermore, the support frame 1 also includes a support base 14, with the lower ends of the first support 11 and the second support 12 respectively connected to the support base 14.

[0055] In this embodiment, the support base 14 serves as the supporting foundation for the first support 11 and the second support 12, enabling the two supports to be stably connected together to form a more stable overall structure. This stability is particularly important when the support frame 1 bears heavy objects or withstands external forces, effectively preventing the support from deforming or collapsing.

[0056] Furthermore, the mounting base 213 of the servo electric cylinder 21 is tilted and fixed on the second fixing plate 15 of the bracket. One end 2131 of the mounting base 213 is lower than the other end 2132 of the mounting base 213. One end 2131 of the mounting base 213 is close to the vertical frame 16 of the support frame, and the other end 2132 of the mounting base 213 is far away from the vertical frame 16 of the support frame. The lead screw 212 is set on the other end 2132, so that the lead screw 212 is tilted toward the vertical frame 16.

[0057] In this embodiment, since the lead screw 212 is inclined toward the vertical frame 16, this inclination angle allows for more reasonable force transmission when the lead screw 212 is under load, reducing stress concentration, improving the stability and reliability of the entire mechanical system, and extending the service life of the equipment.

[0058] Furthermore, the servo motor 211 has a power of 3kW, which enables it to quickly push a load of 533kg.

[0059] It should be noted that in this embodiment, a servo motor 211 with a power of 3kW, a speed of 3000r / min, a torque of 10nm, a stroke of 500, a lead screw pitch of 10mm, and a synchronous belt transmission ratio of 1 is selected. According to calculations, the servo motor 211 has a rated theoretical output of 533kg and a pushing speed of 500mm / s, which can quickly push a load of 533kg.

[0060] During installation, the center of gravity of the swing arm 31 is set at a distance of 1.3m from the rotation shaft 23. The angle formed by the swing arm 31 and the connecting rod 22 is an obtuse angle, which is greater than 90° and less than 120°. In this embodiment, it is 105°, so that the swing amplitude can be more uniform and the deviation is not too large. The lever arm (length of the connecting rod) of the servo electric cylinder is 0.4m.

[0061] During operation, the user wears the VR headset 5, sits on the seat 34, with the pressure bar 341 pressing against the user's thighs. Upon powering on, the electronic control system controls the servo cylinder 21, causing the servo motors 211 on both sides to simultaneously drive the lead screw 212 to extend and retract, moving the connecting rod 22 up and down. This causes the rotating shaft 23 to rotate relative to the bearing seat 1313, which in turn causes the swing arms 31 to swing. The 1.3-meter swing arms on both sides enable the seat 33 to achieve circular motion, swinging forward 40° and backward 32° per second, for a total swing of approximately 72 degrees. This adapts to the complex motion content displayed in the VR headset 5. During this process, various dynamic effects and shooting interactions can also be provided based on the content displayed in the VR headset 5.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
