Description

Technical Field

[0001] This invention relates to the field of virtual reality, and more specifically to a virtual reality motion experience seat. Background Technology

[0002] With the rapid development of virtual reality technology, virtual reality motion experience seats have become a core interactive device connecting virtual scenes with user sensations, and are widely used in various fields such as gaming, science education, simulation training, and cultural tourism. Their core value lies in simulating displacement and posture changes in virtual scenes through the mechanical movement of the seat, allowing users to obtain an immersive sensory experience as if they were actually there. However, existing virtual reality motion experience seats still have many technical shortcomings. Some seats have unreasonable fixing structure designs, some lack ergonomically designed limiting structures, or have inconvenient fixing force adjustment. They either fail to effectively restrain the human body or excessively restrict movement, leading to decreased comfort and fatigue during prolonged use. Therefore, there is an urgent need for a virtual reality motion experience seat that can stably fix the human body during multi-dimensional dynamic movement to overcome the shortcomings of existing technologies. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a virtual reality motion experience seat, which has the advantage of ensuring that the body remains stable while sitting on the seat during virtual reality motion experience.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A virtual reality motion experience seat includes a chair body, a backrest with a back groove, a seat with a seat groove, side rails on both sides of the seat groove, shoulder blocks on both sides of the upper part of the backrest, and a partition block in the middle of the seat.

[0006] Two threaded posts are fixed to the rear side of the chair body. Both threaded posts are inserted into the L-shaped frame. Each threaded post is connected to a nut by thread. The lower end of the L-shaped frame is fixed to the crossbeam. The crossbeam is fixed to the arc panel. Two support plates are fixed to the arc panel. The two support plates are fixed to the two sides of the chair body by screws.

[0007] The left and right ends of the front side of the arc panel are fixed with flat rods, and the left and right sides of the fixing buckle are fixed with side rods. The two side rods are slidably connected to the two flat rods respectively. The side rods are driven to slide by the telescopic rod. The fixing buckle can press against the back of the chair.

[0008] The upper left and right ends of the L-shaped frame are vertically slidably connected with vertical rods. A fixing buckle 2 is fixed between the lower ends of the two vertical rods, and a top rod is fixed between the upper ends of the two vertical rods. A motor 1 is fixed to the upper part of the L-shaped frame. A lead screw is connected to the output shaft of the motor 1. The lead screw and the top rod are threaded together. The fixing buckle 2 can press against the seat plate of the chair.

[0009] The arc panel slides and fits inside the hemispherical bowl. A motor frame is fixed to the rear of the hemispherical bowl, and a second motor is fixed on the motor frame. The output shaft of the second motor passes through the hemispherical bowl and is fixed to the rear side of the crossbeam.

[0010] An arc strip is fixed to the lower side of the hemispherical bowl. An arc groove is provided on the arc strip. The arc strip is slidably connected to the arc seat. Two cylindrical blocks are inserted into the arc seat. Both cylindrical blocks are inserted into the arc groove. A slot hole is provided on the rear side of the hemispherical bowl. A telescopic rod two is fixed to the rear part of the arc seat. A protruding pin is fixed to the movable end of the telescopic rod two. The protruding pin is inserted into the slot hole.

[0011] A vertical shaft is fixed to the lower side of the arc seat. The lower end of the vertical shaft is rotatably connected to the disk through a bearing seat. Gear 1 is fixed on the vertical shaft. Motor 3 is fixed on the disk. Gear 2 is fixed on the output shaft of motor 3. Gear 2 meshes with gear 1 for transmission.

[0012] A sliding shaft is fixed to the lower side of the disc. The disc is set on the upper side of the base plate. Multiple straight holes are arranged in a ring in the middle of the base plate, and the sliding shaft is inserted into the multiple straight holes.

[0013] The bottom plate is connected to a ring via four connecting blocks on its lower side. A groove is provided on the groove rod, which is rotatably connected to the inner side of the ring. The rotation axis of the groove rod is coaxial with the ring. Two limiting plates are fixed on the upper and lower sides of both ends of the groove rod. The two limiting plates on the same side are located on the upper and lower sides of the ring, respectively. A boss is fixed on both the left and right ends of the lower side of the groove rod. A telescopic rod three is fixed on one of the bosses. A sleeve is fixed on the movable end of the telescopic rod three. The sleeve is fitted onto the lower end of the sliding shaft. A retaining ring is fixed on the sliding shaft. The retaining ring is located on the lower side of the sleeve. An L-shaped piece is fixed to the lower end of the sliding shaft. The upper part of the L-shaped piece is slidably connected to the groove on the groove rod.

[0014] A gear ring is fixed on each of the two protrusions. A base frame is fixed on both the left and right ends of the bottom plate. A motor four is fixed on one of the base frames. A gear three is fixed on the output shaft of the motor four. The gear three meshes with the gear ring for transmission.

[0015] The beneficial effects of the virtual reality motion experience seat of the present invention are:

[0016] This invention achieves comprehensive restraint of the human body through a dual fixation design of "ergonomic limiting + active clamping". The backrest and seat grooves of the chair conform to the contours of the human body, while the shoulder blocks, side blocks, and partition blocks provide basic restraint from both sides and the middle. Combined with the active clamping action of fixing buckles one and two, it can effectively prevent the human body from shifting during movements such as tilting, swinging, rotating, and linear movement of the chair. This not only eliminates safety hazards but also ensures accurate matching between the virtual scene and the body sensation, greatly enhancing the immersive experience. Attached Figure Description

[0038] A virtual reality motion experience seat includes a chair body 101. The backrest of the chair body 101 is provided with a back groove 103, the seat plate of the chair body 101 is provided with a seat groove 104, the two sides of the seat groove 104 are provided with side guards 106, the upper two sides of the backrest of the chair body 101 are provided with shoulder blocks 102, and the middle of the seat plate of the chair body 101 is provided with a partition block 105.

[0039] like Figure 5-6 As shown;

[0040] The chair body 101 features a backrest groove 103 that conforms to the curve of the human back, providing support. The seat groove 104 on the seat panel adapts to the contours of the human buttocks, enhancing fit and comfort. Side rails 106 on both sides of the seat groove 104 limit lateral movement of the buttocks, preventing the body from sliding off the seat panel during seat movement. Shoulder blocks 102 on both sides of the upper backrest limit the upper body from tilting to the sides when the seat moves. A divider 105 in the middle of the seat panel separates and positions the legs, further constraining the lower body position. This overall initial positioning of the body on the chair lays the foundation for a stable experience. When sitting in the chair body 101, a virtual reality headset is required for a virtual reality motion simulation experience.

[0041] Two threaded posts 107 are fixed to the rear side of the chair body 101. Both threaded posts 107 are inserted into the L-shaped frame 302. Each threaded post 107 is connected to a nut by thread. The lower end of the L-shaped frame 302 is fixed to the crossbeam 301. The crossbeam 301 is fixed to the arc panel 201. Two support plates 203 are fixed on the arc panel 201. The two support plates 203 are fixed to both sides of the chair body 101 by screws.

[0042] like Figure 5-8 As shown;

[0043] After the two threaded posts 107 on the rear side of the chair body 101 are inserted into the L-shaped frame 302, the chair body 101 and the L-shaped frame 302 can be securely connected by the threaded nuts. At the same time, the two support plates 203 on the curved panel 201 are fixed to both sides of the chair body 101 by screws, forming a double fixing structure of "rear threaded fastening + side screw support". This connection method not only ensures the firmness of the connection between the chair body 101 and the L-shaped frame 302, the crossbeam 301, and the curved panel 201, but also allows the chair body 101 to move stably and synchronously with the curved panel 201, avoiding relative displacement between the chair body 101 and the supporting structure during movement, and ensuring the reliability of the connection.

[0044] The left and right ends of the front side of the arc panel 201 are fixed with flat rods 206, and the left and right sides of the fixing buckle 204 are fixed with side rods 202. The two side rods 202 are slidably connected to the two flat rods 206 respectively. The side rods 202 are driven to slide by the telescopic rod 205. The fixing buckle 204 can press against the back of the chair body 101.

[0045] like Figure 5-8 As shown;

[0046] When a person sits on the chair 101, the telescopic rod 205 is activated and drives the side rod 202 to slide along the horizontal rod 206. The side rod 202 drives the fixing buckle 204 to move towards the back of the chair 101 until the fixing buckle 204 blocks the chest of the person. With the support of the back groove 103, the back of the person is further restricted from swaying back and forth, and the connection stability between the person and the chair 101 is enhanced, preventing the person from tilting forward or backward due to inertia when the seat moves.

[0047] The upper left and right ends of the L-shaped frame 302 are vertically slidably connected with vertical rods 306. A fixing buckle 307 is fixed between the lower ends of the two vertical rods 306, and a top rod 304 is fixed between the upper ends of the two vertical rods 306. A motor 305 is fixed to the upper part of the L-shaped frame 302. A lead screw 303 is connected to the output shaft of the motor 305. The lead screw 303 and the top rod 304 are threaded together. The fixing buckle 307 can press against the seat plate of the chair body 101.

[0048] like Figure 7-8 As shown;

[0049] After motor 305 starts, its output shaft drives the lead screw 303 to rotate. Since the lead screw 303 and the top rod 304 are connected by a thread, and the vertical rod 306 is vertically slidably connected to the L-shaped frame 302, the rotational motion of the lead screw 303 is converted into the vertical linear motion of the top rod 304, which in turn drives the two vertical rods 306 to slide vertically synchronously. When it is necessary to fix the human body, motor 305 drives the lead screw 303 to rotate forward, and the top rod 304 drives the vertical rod 306 to move downward, so that the fixing buckle 307 presses against the position of the human body's legs or buttocks on the seat plate of chair body 101. The downward pressure of fixing buckle 307 restrains the vertical displacement of the lower body, which, together with the back pressing action of fixing buckle 204, forms a double pressing fixation of "back + lower body", further improving the stability of the human body on the chair body.

[0050] The arc panel 201 slides and fits inside the hemispherical bowl 401. A motor frame 404 is fixed to the rear of the hemispherical bowl 401. A second motor 402 is fixed on the motor frame 404. The output shaft of the second motor 402 passes through the hemispherical bowl 401 and is fixed to the rear side of the crossbeam 301.

[0051] like Figure 5-10 As shown;

[0052] The curved panel 201 slides within the hemispherical bowl 401, which provides a curved sliding track and support surface for the panel 201. A second motor 402 is fixed to a motor frame 404 at the rear of the hemispherical bowl 401. Its output shaft passes through the hemispherical bowl 401 and is fixedly connected to the rear side of the crossbeam 301. When the second motor 402 starts, its output shaft drives the crossbeam 301, the L-shaped frame 302, and the chair body 101 to rotate synchronously around the output shaft of the second motor 402. Simultaneously, the curved panel 201 slides along the inner wall of the hemispherical bowl 401, allowing for angle adjustment of the chair body 101 and providing a dynamic experience in the left and right directions. The close fit between the curved panel and the hemispherical bowl ensures stability during rotation.

[0053] An arc strip 407 is fixed to the lower side of the hemispherical bowl 401. An arc groove 410 is provided on the arc strip 407. The arc strip 407 is slidably connected to the arc seat 408. Two cylindrical blocks 409 are inserted into the arc seat 408. Both cylindrical blocks 409 are inserted into the arc groove 410. A slot hole 411 is provided on the rear side of the hemispherical bowl 401. A telescopic rod 406 is fixed to the rear of the arc seat 408. A protruding pin 405 is fixed to the movable end of the telescopic rod 406. The protruding pin 405 is inserted into the slot hole 411.

[0054] like Figure 9-10 As shown;

[0055] The arc strip 407 on the lower side of the hemispherical bowl 401 slides with the cylindrical block 409 on the arc seat 408 through the arc groove 410, allowing the arc strip 407 to slide in an arc along the arc seat 408, thereby driving the hemispherical bowl 401 to swing in an arc synchronously. The telescopic rod 406 is fixed to the rear of the arc seat 408, and the protruding pin 405 at its movable end is inserted into the slot 411 on the rear side of the hemispherical bowl 401. When the telescopic rod 406 extends or retracts, the protruding pin 405 moves in the slot 411 and pushes the hemispherical bowl 401 to swing in an arc, realizing the swing adjustment of the chair body 101 in the front and back directions. Combined with the left and right swing realized by the motor 402, it enriches the dynamic dimension of the seat.

[0056] A vertical shaft 502 is fixed to the lower side of the arc seat 408. The lower end of the vertical shaft 502 is rotatably connected to the disc 501 through a bearing seat. A gear 1 503 is fixed on the vertical shaft 502. A motor 3 505 is fixed on the disc 501. A gear 2 504 is fixed on the output shaft of the motor 3 505. The gear 2 504 meshes with the gear 1 503 for transmission.

[0057] like Figure 9-12 As shown;

[0058] The arc seat 408 is rotatably connected to the disc 501 via the vertical shaft 502 and the bearing seat, allowing the arc seat 408 to rotate around the axis of the vertical shaft 502. After the motor 3 505 starts, its output shaft drives the gear 2 504 to rotate. The gear 2 504 meshes with the gear 1 503 on the vertical shaft 502, transmitting the rotational power of the motor 3 505 to the vertical shaft 502. This, in turn, drives the arc seat 408, the hemispherical bowl 401, and the chair body 101 to rotate synchronously around the vertical shaft 502, achieving a 360° horizontal rotation of the chair body 101 and providing a dynamic experience of rotation for the human body.

[0059] A sliding shaft 506 is fixed to the lower side of the disc 501. The disc 501 is set on the upper side of the base plate 601. The middle part of the base plate 601 is provided with a plurality of straight holes 602 in a ring shape. The sliding shaft 506 is inserted into the plurality of straight holes 602.

[0060] like Figure 11-14 As shown;

[0061] The sliding shaft 506 on the lower side of the disc 501 is inserted into multiple straight holes 602 arranged in a ring in the middle of the base plate 601. The straight holes 602 provide a moving track for the sliding shaft 506. When the disc 501 is driven, the sliding shaft 506 can move along the straight holes 602. Since the multiple straight holes 602 are arranged in a ring, the sliding shaft 506 can move linearly in eight directions, thereby driving the upper arc seat 408, hemispherical bowl 401, and chair body 101 to move linearly in eight directions. This allows the chair body 101 to move rapidly in one of the eight directions, enabling the person sitting on the chair body 101 to move quickly in a certain direction, providing the user with a precise and strong sense of direction.

[0062] The bottom plate 601 is connected to a ring 603 via four connecting blocks 604 on its lower side. A groove is provided on the groove rod 607, which is rotatably connected to the inner side of the ring 603. The rotation axis of the groove rod 607 is coaxial with the ring 603. Two limiting pieces 612 are fixed on the upper and lower sides of both ends of the groove rod 607. The two limiting pieces 612 on the same side are located on the upper and lower sides of the ring 603, respectively. The lower left and right ends of the groove rod 607 are fixed with a boss 605. A telescopic rod 606 is fixed on one of the bosses 605. A sleeve 608 is fixed on the movable end of the telescopic rod 606. The sleeve 608 is fitted on the lower end of the sliding shaft 506. A retaining ring 507 is fixed on the sliding shaft 506. The retaining ring 507 is located on the lower side of the sleeve 608. An L-shaped piece 508 is fixed on the lower end of the sliding shaft 506. The upper part of the L-shaped piece 508 is slidably connected to the groove on the groove rod 607.

[0063] like Figure 11-14 As shown;

[0064] The base plate 601 is securely connected to the ring 603 via four connecting blocks 604, providing a stable mounting foundation for the grooved rod 607. The grooved rod 607 is rotatably connected to the inner side of the ring 603 via limiting plates 612 on both ends. The two limiting plates 612 on the same side are respectively locked onto the upper and lower surfaces of the ring 603, which not only restricts the axial displacement of the grooved rod 607, but also ensures that the grooved rod 607 can rotate flexibly around the axis of the ring 603. When it is necessary to drive the sliding shaft 506 to move the disc 501, the telescopic rod 606 is activated and performs telescopic movement. The sleeve 608 at its movable end applies a pushing or pulling force to the sliding shaft 506 through the retaining ring 507. At the same time, the L-shaped piece 508 at the lower end of the sliding shaft 506 slides synchronously along the groove on the grooved rod 607. Since the straight holes 602 on the base plate 601 are arranged in a ring, corresponding to the straight movement trajectory in eight directions, the groove rod 607 can be rotated on the ring 603 to coincide with the direction of one of the straight holes 602. Then, the sliding shaft 506 can be precisely controlled to move along the target straight hole 602, and finally the disc 501 can drive the chair body 101 to move stably in any one of the eight directions, providing users with a precise and strong sense of direction.

[0065] A gear ring 609 is fixed on each of the two protrusions 605. A base frame 613 is fixed on both the left and right ends of the lower side of the base plate 601. A motor 610 is fixed on one of the base frames 613. A gear 611 is fixed on the output shaft of the motor 610. The gear 611 meshes with the gear ring 609 for transmission.

[0066] like Figure 13-14 As shown;

[0067] Motor 4 610 is fixed on the base frame 613 on the underside of the base plate 601. The base frame 613 provides stable support for motor 4 610, ensuring stability during power output. After motor 4 610 starts, its output shaft drives gear 3 611 to rotate at high speed. Gear 3 611 meshes with the gear ring 609 fixed on the two bosses 605, converting the rotational power of motor 4 610 into the circumferential motion of gear ring 609, which in turn drives the grooved rod 607 to rotate synchronously around the axis of the ring 603. This allows for precise switching of the direction of the linear hole 602 corresponding to the sliding shaft 506, enabling rapid switching of the eight movement directions of the chair body 101.
