[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1 to 3 As shown, a multi-person seat displacement device includes: a base 2, a seat body 3, and a drive assembly 4. At least two parallel guide rails 21 are fixed on the base 2. The seat body 3 has a bracket 31 at its lower part. The bracket 31 is provided with sliders 32 corresponding to the guide rails 21. The sliders 32 slide with the guide rails 21, and two of the sliders 32 are distributed on both sides of the bracket 31. The drive assembly 4 includes a servo motor 41, a gear 42, and a rack 43. The rack 43 is fixed on the base 2. The servo motor 41 is connected to the gear 42 through a reducer 44. The gear 42 meshes with the rack 43.

[0030] In this application, the core principle of the multi-person seat displacement device is to convert the rotational motion of the servo motor 41 into the linear motion of the seat body 3 through the transmission of gear 42 and rack 43. The specific process is as follows: After the servo motor 41 is started, the speed is reduced and the torque is increased through the reducer 44, which drives the gear 42 to rotate. The rotating gear 42 meshes with the rack 43 fixed on the base 2, converting the rotational motion into linear motion, pushing the seat body 3 to slide along the guide rail 21. The sliders 32 on both sides of the bracket 31 cooperate with the guide rail 21 of the base 2 to ensure that the seat remains stable during the movement and avoids deviation or tilting.

[0031] Furthermore, this application is used in conjunction with a six-degree-of-freedom device, which is located below the base 2, thereby controlling the orientation of the base 2 for position adjustment. Then, by adjusting the fore-and-aft position of the seat, the immersive interactive experience is further enhanced. The seat of this application can move forward and backward independently.

[0032] In this application, standardized mechanical components such as guide rail 21, slider 32, gear 42 and rack 43 are used, which have low manufacturing cost, convenient maintenance and low failure rate. The design of parallel guide rail 21 and sliders on both sides distributes the weight of the seat body 3, improves the stability and load-bearing capacity of the device, and is suitable for multiple people to sit at the same time. When combined with a six-degree-of-freedom device, it can enable customers to deepen their immersive interactive experience.

[0033] Specifically, the guide rail 21 is provided with a receiving groove 22, and a limiting part 221 is provided on the inner wall of the receiving groove 22. A limiting wheel 321 is rotatably provided at the bottom of the slider 32, and a limiting groove 3211 is provided on the limiting wheel 321. The limiting part 221 extends into the limiting groove 3211.

[0034] When the seat is subjected to lateral force or during rapid movement, the limiting wheel 321 can effectively prevent the slider 32 from disengaging from the guide rail 21, greatly improving the safety and stability of the seat during displacement.

[0035] Specifically, limit blocks 23 are provided at both ends of the guide rail 21.

[0036] The limit block can define a clear limit for seat displacement, effectively preventing the seat from detaching from the guide rail 21 due to excessive displacement and avoiding safety accidents caused by it.

[0037] Specifically, it also includes a base plate 5, which is fixed on the base 2 and is used to cover the guide rail 21 and the slider 32. The base 2 has a first guide hole 51 corresponding to the guide rail 21. The bracket 31 is connected to the slider 32 through a connecting frame 6. The connecting frame 6 includes a first connecting part 61, a vertical plate 62 and a second connecting part 63 connected in sequence. The first connecting part 61 is connected to the bracket 31 and the second connecting part 63 is connected to the slider 32. The vertical plate 62 passes through the first guide hole 51.

[0038] The base plate 5 is fixed on the base 2 to cover the guide rail 21 and the slider 32, which can effectively prevent personnel from accidentally touching the guide rail 21 and the slider 32 during operation, avoiding safety accidents such as pinching and scratching. At the same time, the base plate 5 can block dust, debris and other objects from entering the mating part of the guide rail 21 and the slider 32, preventing foreign objects from affecting the normal sliding of the seat, ensuring the long-term stable operation of the device, and reducing failures and maintenance costs caused by debris.

[0039] Specifically, the first guide hole 51 is offset from the guide rail 21 and the slider 32.

[0040] When the first guide hole 51 is misaligned with the guide rail 21 and the slider 32, even if foreign objects enter through the gap between the base plate 5 and the base 2, they will have difficulty directly reaching the guide rail 21 and the slider 32, thus reducing the jamming when the guide rail 21 and the slider 32 move relative to each other when foreign objects enter.

[0041] Specifically, the base plate 5 is composed of multiple splicing plates 52.

[0042] The base plate 5, which is composed of multiple splicing panels 52, does not require the overall handling or hoisting of large panels during installation. Installers can move the small splicing panels 52 one by one to the installation position for splicing. When there is a problem with the internal structure of the base plate 5 or the corresponding base plate 5, it is not necessary to replace the entire base plate 5. Only the corresponding splicing panel 52 needs to be removed for maintenance.

[0043] Specifically, a second guide hole 53 is also provided on the base plate 5, and the rack 43 is disposed at the corresponding second guide hole 53.

[0044] Specifically, the rack 43 is positioned at the middle of the corresponding seat body 3.

[0045] The rack 43 is subjected to balanced force in the middle position, and the wear of its various parts is relatively uniform, thus improving its service life.

[0046] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0047] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the meaning of "and / or" throughout the text includes three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0048] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0049] The specific embodiments described herein are merely illustrative examples of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from this utility model or exceeding the scope defined by the appended claims.
