Description

Technical Field

[0001] This utility model relates to the field of VR experience equipment technology, specifically a VR experience seat vibration structure. Background Technology

[0002] Virtual reality (VR) technology is a novel and practical technology that emerged in the 20th century. It encompasses computer science, electronic information, and simulation technology, and its basic implementation involves computer-simulated virtual environments to create a sense of immersion. With the continuous development of social productivity and science and technology, the demand for VR technology is increasingly strong across various industries. VR technology has also made significant progress and is gradually becoming a new field of scientific and technological research. To provide users with a more realistic experience, existing VR devices are also equipped with multi-functional seats, which feature vibration capabilities to provide users with vibrations that are compatible with the VR field of vision.

[0003] For example, Chinese patent CN213550735U discloses a vibrating seat for VR experiences, including a seat body, a vibration component, and a base arranged sequentially from top to bottom. The vibration component includes a support plate, a push plate, and a top plate arranged sequentially from bottom to top, and also includes a telescopic component and multiple pull rods. The support plate is fixedly connected to the seat plate, and the top of the support plate is fixedly connected to the telescopic component. The output end of the telescopic component is vertically upward, passes through the push plate, and is fixedly connected to the top plate. The top plate is fixedly connected to the seat body. Multiple pull rods are evenly arranged around the top plate. One end of each pull rod is hinged to the top plate, and the other end is slidably hinged to the support plate. The pull rods abut against the outer wall of the push plate. This design solves the problem that existing VR experience vibrating seats are easily damaged and have a short service life due to user reactions.

[0004] The technical solution described in this paper has a fixed angle for the vibration component during actual use. It cannot be adaptively adjusted according to VR scenarios such as acceleration and leaning forward while driving or recoil and leaning backward while shooting, which greatly reduces the user's immersion and the realism of the scene. Utility Model Content

[0005] The purpose of this invention is to provide a vibration structure for a VR experience seat to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A VR experience seat vibration structure includes a base, an angle adjustment component, and a vibration component. The angle adjustment component is disposed above the base, and the vibration component is disposed above the angle adjustment component. The angle adjustment component is used to adjust the angle of the vibration component to tilt the seat forward or backward. The vibration component is used to realize the reciprocating motion of the mounting plate to achieve a vibration effect on the seat. The angle adjustment component includes a mounting base, the bottom end of which is fixedly connected to the upper end of the base. Mounting holes are provided on both sides of the mounting base, and rotating shafts are rotatably connected inside the two mounting holes. A spherical seat is installed between the pair of rotating shafts. A servo motor is installed on the outer wall of the mounting base, and the output end of the servo motor is connected to one of the rotating shafts.

[0008] Furthermore, the mounting base has a groove at its inner bottom end, the inner wall of the groove is rotatably engaged with the outer wall of the spherical base, the bottom end of the spherical base has a sliding groove, the sliding groove has a slide bar inside, the slide bar is located at the center of the groove, and the bottom end of the slide bar is fixedly connected to the inner wall of the groove.

[0009] The beneficial effect of adopting the above-mentioned further solution is that when the spherical seat rotates, the outer wall of the spherical seat is always in contact with the inner wall of the groove; through the cooperation of the slider and the slide groove, the rotation of the spherical seat is guided. When the servo motor drives the rotating shaft to tilt the spherical seat forward or backward, the slider slides along the slide groove, which can not only ensure smooth rotation, but also limit the maximum rotation angle through the length of the slide groove, avoiding excessive tilting that could cause user discomfort.

[0010] Furthermore, the inner wall of the groove and the outer wall of the slide bar are in sliding fit, both the groove and the slide bar are arc-shaped, and the length of the groove is greater than the length of the slide bar.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the length of the slide groove is greater than that of the slide bar. When the angle adjustment is close to the maximum angle, the end of the slide bar fits into the end of the slide groove, limiting the angle adjustment range of forward tilting or backward tilting, and preventing it from exceeding the angle of human comfort.

[0012] Furthermore, the vibration assembly includes a conical seat, the bottom end of which is fixedly connected to the upper end of a spherical seat. A support is installed on the upper end of the conical seat, and a circular plate is provided at the center of the upper end of the support. A plurality of first connecting seats are installed on the outer side wall of the circular plate. A connecting rod is installed on both sides of the plurality of first connecting seats. A second connecting seat is installed between a pair of connecting rods. An mounting plate is installed on the top surface of the plurality of second connecting seats.

[0013] The beneficial effects of adopting the above-mentioned further solution are that the circular plate is connected to the mounting plate through several first connecting seats, connecting rods and second connecting seats to form a multi-point support. When the circular plate moves up and down, the mounting plate moves up or down under the action of the first connecting seats, connecting rods and second connecting seats. At the same time, it will not tilt due to single-point force, such as one side being higher and the other side being lower, so that users can feel uniform vibration, which is close to the real scene. The bottom end of the conical seat is connected to the spherical seat, and the upper end expands the support area. With the stability of the support, the impact force generated by the vibration can be distributed to the entire angle adjustment assembly, avoiding excessive force on the top of the telescopic cylinder and deformation, and ensuring the structural reliability under long-term high-frequency vibration.

[0014] Furthermore, the second connecting seats and the first connecting seats are all distributed in a ring at equal intervals.

[0015] The beneficial effects of adopting the above-mentioned further solution are that the plurality of second connecting seats and the plurality of first connecting seats are all distributed in a ring at equal distances, so that the load of each link, first connecting seat and second connecting seat is exactly the same, avoiding bending of a link or breakage of a first connecting seat or a second connecting seat due to uneven distribution, thus extending the service life of the vibration component; at the same time, the plurality of second connecting seats and the plurality of first connecting seats are all distributed in a ring at equal distances, so that the vibration of the mounting plate is completely symmetrical in the circumferential direction. When simulating uniform vibration in a VR scene, the vibration intensity felt by different parts of the user's body is the same, and there will be no distortion of one side vibrating more strongly than the other, thus enhancing the sense of immersion in the scene.

[0016] Furthermore, a circular hole is provided at the center of the top surface of the support, and a cavity is provided inside the support. A telescopic cylinder is installed at the bottom of the cavity, and the movable end of the telescopic cylinder passes through the circular hole and is fixedly connected to the bottom of the circular plate.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, by setting up a telescopic cylinder, when the telescopic cylinder is working, it can drive the circular plate to move up and down, and realize the up and down movement of the mounting seat under the support and connection of the first connecting seat, connecting rod and second connecting seat. The air compressor first compresses the normal pressure air into high pressure gas, and delivers it to the air tank for storage and pressure stabilization through the air pipe. The compressed air output from the air tank is controlled by the main pipeline valve to enter the filter to filter moisture and impurities, and the pressure regulating valve is adjusted to the working pressure required by the cylinder. The processed compressed air is connected to the solenoid valve through the air pipe, and the solenoid valve controls the opening and closing and reversal of the air circuit according to the electrical signal. The outlet of the solenoid valve is connected to the two air inlets of the cylinder through the air pipe, driving the piston rod to complete the extension or retraction action.

[0018] Furthermore, the connecting rods, the first connecting seats, and the second connecting seats are all made of metal steel.

[0019] The beneficial effect of adopting the above-mentioned further solution is that by setting the first connecting seat, the connecting rod and the second connecting seat to be made of metal steel, metal steel can withstand the alternating stress generated by high-frequency vibration, and is not prone to problems such as connecting rod bending or the first or second connecting seat breaking, which is suitable for long-term high-frequency use of VR experience seats.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: In this VR experience seat vibration structure, when the servo motor drives the rotating shaft to tilt the spherical seat forward or backward, the slide bar slides along the slide groove to guide the rotation of the spherical seat and ensure smooth rotation; the slide groove is longer than the slide bar, and when the angle adjustment is close to the maximum angle, the end of the slide bar fits with the end of the slide groove, limiting the angle adjustment range of forward or backward tilting to prevent exceeding the comfortable angle for the human body. The maximum rotation angle is limited by the length of the slide groove to avoid excessive tilting that could cause user discomfort; the combined use of the angle adjustment component and the vibration component makes the tilting vibration felt by the user in VR scenes such as driving, shooting, and adventure more realistic, greatly enhancing the sense of immersion in the scene.

[0030] Please see Figures 1-5This utility model provides a technical solution: a groove 25 is formed at the bottom of the mounting base 21, and the inner wall of the groove 25 is rotatably engaged with the outer wall of the spherical base 23. A sliding groove 26 is formed inside the bottom of the spherical base 23, and a sliding strip 27 is provided inside the sliding groove 26. The sliding strip 27 is located at the center of the groove 25, and the bottom end of the sliding strip 27 is fixedly connected to the inner wall of the groove 25. The inner wall of the sliding groove 26 and the outer wall of the sliding strip 27 are slidably engaged. Both the sliding groove 26 and the sliding strip 27 are arc-shaped. The length of the slide groove 26 is greater than the length of the slide bar 27. When the spherical seat 23 rotates, the slide bar 27 slides along the slide groove 26 to guide the rotation of the spherical seat 23 and ensure that the spherical seat 23 rotates smoothly. The length of the slide groove 26 is greater than the length of the slide bar 27. When the angle adjustment is close to the maximum angle, the end of the slide bar 27 fits with the end of the slide groove 26, limiting the angle adjustment range of forward tilting or backward tilting, preventing it from exceeding the angle of human comfort. The maximum rotation angle is limited by the length of the slide groove 26 to avoid excessive tilting that may cause user discomfort.

[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] Please see Figures 1-5This utility model provides a technical solution: the vibration component 3 includes a conical seat 31, the bottom end of which is fixedly connected to the upper end of a spherical seat 23. A support 32 is installed on the upper end of the conical seat 31. A circular plate 34 is provided at the center of the upper end of the support 32. A plurality of first connecting seats 35 are installed on the outer side wall of the circular plate 34. A connecting rod 36 is installed on both sides of the outer side of the plurality of first connecting seats 35. A second connecting seat 37 is installed between a pair of connecting rods 36. An mounting plate 38 is installed on the top surface of the plurality of second connecting seats 37. The plurality of second connecting seats 37 and the plurality of first connecting seats 35 are all distributed in a ring at equal intervals. A circular hole is opened at the center of the top surface of the support 32. A cavity is opened inside the support 32. A telescopic cylinder 33 is installed at the bottom of the cavity. The movable end of the telescopic cylinder 33 passes through the circular hole and is fixedly connected to the bottom end of the circular plate 34. The connecting rods 36, the first connecting seats 35, and the second connecting seats 37 are all made of metal steel. When the telescopic cylinder 33 works, it can drive the circular plate 34 to move up and down. The circular plate 34 is connected to the mounting plate 38 through the first connecting seats 35, connecting rods 36, and second connecting seats 37, forming a multi-point support. When the circular plate 34 moves up and down, the mounting plate 38 moves up or down under the action of the first connecting seats 35, connecting rods 36, and second connecting seats 37. At the same time, it will not tilt due to single-point force, such as one side being higher than the other, so that the user feels uniform vibration, which is close to the real scene. Since the first connecting seats 35, connecting rods 36, and second connecting seats 37 are made of metal steel, metal steel can withstand the alternating stress generated by high-frequency vibration, and it is not easy to have problems such as bending of the connecting rods 36 or breakage of the first connecting seats 35 or second connecting seats 37.

[0033] Specifically, the working principle of this VR experience seat vibration structure is as follows: During use, holes are drilled in the mounting plate 38 using a hand drill, and the VR experience seat is installed on the mounting plate 38 using fastening bolts. When the user experiences VR scenarios such as driving, shooting, or adventure, the servo motor 24 drives the rotating shaft 22, causing the spherical seat 23 to tilt forward or backward. The slider 27 slides along the groove 26, guiding the rotation of the spherical seat 23 and ensuring smooth rotation. The groove 26 is longer than the slider 27. When the angle adjustment approaches the maximum angle, the end of the slider 27 engages with the end of the groove 26, limiting the tilting or backward adjustment range and preventing it from exceeding the comfortable angle for the human body. The maximum rotation angle is controlled to avoid excessive tilting that could cause user discomfort. When the telescopic cylinder 33 is working, it can drive the circular plate 34 to move up and down. The circular plate 34 is connected to the mounting plate 38 through several first connecting seats 35, connecting rods 36 and second connecting seats 37, forming a multi-point support. When the circular plate 34 moves up and down, the mounting plate 38 moves up or down under the action of the first connecting seats 35, connecting rods 36 and second connecting seats 37. At the same time, it will not tilt due to single-point force, such as one side being higher and the other side being lower, so that the user can feel uniform vibration, which is close to the real scene. The combined use of the angle adjustment component 2 and the vibration component 3 makes the tilting vibration felt by the user in the VR scene more realistic, greatly enhancing the sense of scene immersion.

[0034] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
