Description

Technical Field

[0001] This invention relates to the field of virtual reality technology, specifically to a virtual reality auxiliary equipment base. Background Technology

[0002] Virtual reality (VR) technology is a computer simulation system that can create and experience virtual worlds. It uses computers to generate a simulated environment, which is an interactive, three-dimensional dynamic visual and physical behavior system simulation that integrates multi-source information, immersing users in the environment. VR technology is an important direction of simulation technology, and it is a collection of simulation technology with computer graphics, human-computer interface technology, multimedia technology, sensing technology, network technology, and other technologies. VR technology is a challenging interdisciplinary frontier discipline and research field. VR technology mainly includes aspects such as simulated environment, perception, natural skills, and sensing devices. VR assistive devices are an important component of VR equipment, used to enhance the user's sense of immersion and realism.

[0003] The existing virtual reality assistive device base disclosed in application number 201721529331.X can suspend the user, simulating scenarios such as gliding or flying in the air, making the user's experience in the virtual reality scene more realistic and immersive. In addition, to increase the fun of the virtual reality assistive device provided in this embodiment and increase the user's sense of immersion, a fan can blow air towards the user, simulating the user being blown by the wind in the air, making the user more immersive and having a stronger sense of presence. Before being suspended, the user stands on the platform, puts on the backpack, and then the lifting frame rises, causing the platform to rise. After reaching the predetermined position, the lengths of the first and second pull ropes are adjusted. After adjustment, the lifting frame descends, causing the platform to descend. The lifting structure provides a safe support platform for the user and enhances the user's experience. However, when the user experiences rotating or tilting scenes, the user's body cannot rotate or tilt according to the scene, resulting in insufficient immersion and realism, which affects the user's experience. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a virtual reality auxiliary equipment base that can rotate or tilt the user's body to increase the sense of immersion and realism, improve the user experience, and effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a virtual reality assistive device base, comprising a mounting plate, a tilting unit, and a rotating unit;

[0006] Mounting plate: The mounting plate has a mounting post in the middle of its upper surface. A spherical connecting block is fixedly connected to the upper end of the mounting post. A connecting post is provided above the spherical connecting block. A mounting groove is opened on the lower surface of the connecting post. The spherical connecting block is placed in the mounting groove. A seat is provided at the upper end of the connecting post. Four grooves are provided at equal angles on the lower surface of the seat.

[0007] Tilting unit: The tilting unit includes connecting rods, electric push rods and baffles. There are four electric push rods, which are respectively placed around the upper surface of the mounting plate. Each electric push rod has a connecting rod at its upper end, and each connecting rod has a support plate at its upper end. The upper end of the support plate is placed in a groove. There are four baffles, which are respectively placed around the upper surface of the mounting plate. The baffles are fixedly connected to the mounting plate.

[0008] Rotating unit: The rotating unit includes a motor, a connecting shaft and a base plate. The base plate is placed below the mounting plate. The upper surface of the base plate is provided with an annular groove. The motor is placed in the middle of the upper surface of the base plate. The output end of the motor is fixedly connected to one end of the connecting shaft. The other end of the connecting shaft is fixedly connected to the lower surface of the fixed plate. The upper surface of the fixed plate is fixedly connected to the lower surface of the mounting plate.

[0009] It also includes a PLC controller, which is placed on the seat. The input terminal of the PLC controller is electrically connected to the output terminal of an external power supply, and the output terminal of the PLC controller is electrically connected to the input terminal of the motor and the electric actuator.

[0010] Furthermore, it also includes handles, of which there are two and are located at both ends of the upper surface of the seat. The handles are fixedly connected to the seat to facilitate the user's body stability.

[0011] Furthermore, it also includes shock-absorbing pads, which consist of four pieces and are placed on the upper surface of the baffle. The shock-absorbing pads are fixedly connected to the baffle to prevent the seat from being damaged by impact between the seat and the baffle when tilted.

[0012] Furthermore, it also includes elastic bands and safety locks. There are two elastic bands, which are placed at both ends of the seat. One end of each elastic band is fixedly connected to the seat, and the other end of each elastic band is equipped with a safety lock that works together to prevent the user from being thrown out due to centrifugal force during rotation, thus ensuring the user's safety.

[0013] Furthermore, it also includes a backrest cushion, which is placed on the back of the seat and filled with anti-deformation sponge. The cushion is fixedly connected to the seat to increase the user's comfort when sitting in the seat.

[0014] Furthermore, it also includes four springs, each sleeved on the connecting rod. The springs are the same length as the connecting rod, reducing the vibration felt by the user when the electric push rod pushes the connecting rod to contact the seat.

[0015] Furthermore, it also includes an anti-slip mat, which is a single piece placed on the lower surface of the base plate and fixedly connected to the base plate to increase the stability of the base plate.

[0016] Furthermore, it also includes four sliding rods, which are placed at equal angles on the lower surface of the mounting plate. One end of the sliding rod is fixedly connected to the mounting plate, and the other end of the sliding rod is placed in a sliding groove, which can be used to facilitate the rotation of the mounting plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This virtual reality assistive device base has the following advantages:

[0018] 1. A tilting unit is set up. When the seat needs to tilt in one direction, the four electric push rods are opened, which retracts the electric push rod in that direction and the two electric push rods adjacent to it, and extends the electric push rod opposite to it. This allows the electric push rods to push the seat to tilt. The seat can be tilted in multiple directions, which increases the sense of immersion and realism.

[0019] 2. A rotating unit is also provided. The motor drives the connecting shaft to rotate, which in turn drives the fixing plate to rotate. The fixing plate then drives the mounting plate to rotate, thereby rotating the seat and allowing the user to rotate, thus improving the user experience. Attached Figure Description

[0026] Example 1:

[0027] The virtual reality assistive device base includes a mounting plate 1, a tilting unit 3, and a rotating unit 4. The mounting plate 1 has a mounting post 2 in the center of its upper surface. A spherical connecting block 17 is fixedly connected to the upper end of the mounting post 2. A connecting post 5 is located above the spherical connecting block 17. A mounting groove is formed on the lower surface of the connecting post 5, and the spherical connecting block 17 is placed in the mounting groove. A seat 6 is located at the upper end of the connecting post 5. Four grooves are formed at equal angles on the lower surface of the seat 6. Two handles 8 are located at both ends of the upper surface of the seat 6 and are fixedly connected to the seat 6, allowing the user to easily maintain their body position. Stability, tilting unit 3: The tilting unit 3 includes connecting rods 31, electric push rods 32, and baffles 33. There are four electric push rods 32, each positioned around the upper surface of the mounting plate 1.

There are four baffles 33, each positioned around the upper surface of the mounting plate 1. The baffles 33 are fixedly connected to the mounting plate 1. When the seat 6 needs to tilt in one direction, the four electric push rods 32 are opened, causing the electric push rod 32 in that direction and its two adjacent electric push rods 32 to retract. The corresponding electric push rod 32 extends, thereby pushing the seat 6 to tilt. The seat 6 can be tilted in multiple directions, increasing immersion and realism. The rotating unit 4 includes a motor 41, a connecting shaft 42, and a base plate 43. The base plate 43 is placed below the mounting plate 1.

The output end of the motor 41 is fixedly connected to one end of the connecting shaft 42, and the other end of the connecting shaft 42 is fixedly connected to the lower surface of the fixing plate 15. The upper surface of the fixing plate 15 is connected to the mounting plate 1. The lower surface is fixedly connected. When the seat 6 needs to be rotated, the motor 41 is turned on, which drives the connecting shaft 42 to rotate. The connecting shaft 42 will drive the fixing plate 15 to rotate, and the fixing plate 15 will drive the mounting plate 1 to rotate, thereby driving the seat 6 to rotate, achieving the purpose of driving the user to rotate and improving the user experience. It also includes a PLC controller 7, which is placed on the seat 6. The input terminal of the PLC controller 7 is electrically connected to the output terminal of the external power supply, and the output terminal of the PLC controller 7 is electrically connected to the input terminal of the motor 41 and the electric push rod 32.

[0028] Example 2:

[0029] The difference between this embodiment and Embodiment 1 is that:

[0030] In this embodiment, there are four shock-absorbing pads 13, which are respectively placed on the upper surface of the baffle 33. The shock-absorbing pads 13 are fixedly connected to the baffle 33. There are two elastic bands 9, which are respectively placed at both ends of the seat 6. One end of the elastic band 9 is fixedly connected to the seat 6, and the other end of the elastic band 9 is respectively provided with safety locks 10 that cooperate with each other.

[0031] Specifically, the shock-absorbing pad 13 can prevent the seat 6 from being damaged by the impact between the seat 6 and the baffle 33 when tilting, and the elastic band 9 and safety lock 10 can prevent the user from being thrown out due to centrifugal force when rotating, thus ensuring the user's safety.

[0032] Example 3:

[0033] The difference between this embodiment and Embodiment 1 is that:

[0034] In this embodiment, the cushion 11 is placed on the back of the seat 6. The cushion 11 is filled with anti-deformation sponge. The cushion 11 is fixedly connected to the seat 6. There are four springs 12, which are respectively sleeved on the connecting rod 31. The springs 12 and the connecting rod 31 have the same length.

[0035] Specifically, the cushion 11 can be used to increase the comfort of the user when sitting on the seat 6, and the spring 12 is used to increase the stability of the base plate 43.

[0036] Example 4:

[0037] The difference between this embodiment and Embodiment 1 is that:

[0038] In this embodiment, the anti-slip mat 14 is a single piece and is placed on the lower surface of the base plate 43. The anti-slip mat 14 is fixedly connected to the base plate 43. There are four sliding rods 16, which are placed at equal angles on the lower surface of the mounting plate 1. One end of the sliding rod 16 is fixedly connected to the mounting plate 1, and the other end of the sliding rod 16 is placed in the sliding groove.

[0039] Specifically, the anti-slip pad 14 can be used to increase the stability of the base plate 43, and the slide bar 16 can be used to facilitate the rotation of the mounting plate 1.

[0040] In use: When the seat 6 needs to be tilted in one direction, open the four electric push rods 32, causing the electric push rods 32 in that direction and the two adjacent electric push rods 32 to retract, and causing the opposite electric push rods 32 to extend. This allows the electric push rods 32 to push the seat 6 to tilt, enabling the seat 6 to tilt in multiple directions, increasing immersion and realism. When the seat 6 needs to be rotated, turn on the motor 41, which drives the connecting shaft 42 to rotate. The connecting shaft 42 then drives the fixing plate 15 to rotate, which in turn drives the mounting plate 1 to rotate, thereby rotating the seat 6 and achieving the purpose of rotating the user, improving the user experience.

[0041] It is worth noting that the motor 41 disclosed in this embodiment can be model Y160M1-2, the electric push rod 32 can be model ANT-03, and the PLC controller 7 can be model Siemens S7-200.
