Description
Technical Field
[0001] This application relates to the field of multidimensional simulation technology of planar space, and in particular to a floor element and an omnidirectional moving device. Background Technology
[0002] XR (Extended Reality) technology refers to the use of computers to combine the real and virtual worlds, creating an interactive virtual environment. It's a collective term for various technologies including Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR). XR technology is fundamentally mature and has already demonstrated significant value in certain areas of virtual and mixed reality. Its immersive experience offers a visual presentation completely different from traditional technologies, but it largely remains at the level of sensory interaction, such as visual perception. MR technology, to some extent, blends virtual and physical real-world scenes, expanding the application scope of virtual scenes and demonstrating significant value in scientific experiments, engineering practices, simulations, education, and certain interactive scenarios. However, in existing technologies, the user's interaction process is limited by physical space, thus affecting the user's viewing or interactive experience. Summary of the Invention
[0003] In view of this, the embodiments of this application aim to provide a floor element and an omnidirectional moving device to solve the problem that the user's interaction process is limited by physical space in the prior art.
[0004] To achieve the above objectives, one aspect of this application provides a floor element, comprising:
[0005] Plate; and
[0006] A connection structure, including a connector connected to the plate body;
[0007] The adjacent floor elements are constrained by the connecting body. Under the action of the constraining force, the adjacent floor elements are connected to each other and can move together. When the floor element is subjected to a separation force that can overcome the constraining force, it separates from the adjacent floor element.
[0008] Furthermore, the connector is a magnet, and a mounting groove is formed on the plate, with the magnet located within the mounting groove.
[0009] Furthermore, the magnet is rotatably disposed within the mounting groove so that the magnets at corresponding positions on any two sides of adjacent floor elements can attract each other.
[0010] Furthermore, the connection structure also includes a connecting shaft, which is arranged along the length direction of the plate side corresponding to the mounting groove and connected to both ends of the mounting groove. The magnet is connected to the connecting shaft. The connecting shaft is fixed to both ends of the mounting groove, and the magnet is rotatably mounted on the connecting shaft.
[0011] Furthermore, the connection structure also includes a connecting shaft, which is arranged along the length direction of the plate side corresponding to the mounting groove and connected to both ends of the mounting groove, and the magnet is connected to the connecting shaft; the connecting shaft is rotatably arranged at both ends of the mounting groove, and the magnet is rotatably arranged on the connecting shaft.
[0012] Furthermore, the connection structure also includes a connecting shaft, which is arranged along the length direction of the plate side corresponding to the mounting groove and connected to both ends of the mounting groove. The magnet is connected to the connecting shaft. The connecting shaft is rotatably arranged at both ends of the mounting groove, and the magnet is fixed on the connecting shaft.
[0013] Furthermore, the connection structure also includes an elastic element connected to the connecting body to buffer the force on the connecting body along the length direction of the plate edge.
[0014] Furthermore, the elastic element is provided at both ends of the connector.
[0015] Furthermore, two connecting structures are symmetrically spaced along the length of each side of the plate.
[0016] Furthermore, the side length of the plate is L, and the distance between the center of the connector and the end of the edge of the plate is 0.15L to 0.3L.
[0017] Furthermore, the thickness of the plate is H, and the distance between the center of the connector and the plate along the thickness direction is 0.2H to 0.3H.
[0018] Furthermore, the projection of the plate along the thickness direction is a parallelogram.
[0019] Furthermore, the parallelogram is a square.
[0020] Furthermore, the floor element also includes a rubber patch or a rough-surfaced plastic patch disposed on each side of the board.
[0021] In another aspect of this application, an omnidirectional mobile device is provided, comprising:
[0022] The base has a walking area for interaction, and configuration areas disposed outside the walking area along a first direction and a second direction, respectively.
[0023] The floor element described in any one of the foregoing claims, wherein a plurality of the floor elements are laid along the first direction and the second direction on the walking area and at least a portion of the configuration area; and
[0024] A drive unit is configured to drive the floor element in the configuration area to move the floor element in the walking area, so that the floor element moves along the first direction or along the second direction.
[0025] The required displacement of the floor element is decomposed into displacements in the first direction and the second direction. The driving unit drives the floor element to move the corresponding displacement along the first direction or the second direction. The first direction and the second direction are not parallel.
[0026] Furthermore, the omnidirectional moving device also includes a guide plate, one side of which is connected to the outside of the configuration area, and the contact surface between the guide plate and the floor element is inclined.
[0027] This application provides a floor element comprising a plate and a connecting structure. The connecting structure includes a connector connected to the plate; adjacent floor elements are constrained by the connector, and are connected to each other and can move together under the action of the constraint. When a floor element is subjected to a separation force capable of overcoming the constraint, it separates from its adjacent counterpart. By setting the connector to create a constraint between adjacent floor elements, they are combined and laid on the walking area and the configuration area under the action of the constraint, facilitating users in the virtual scene to walk realistically in the walking area of the real scene.

[0039] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.
[0040] The directional terms used in the description of this application are for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application.
[0041] One aspect of this application provides a floor element, see [link to previous document]. Figures 1-2 As shown, it includes a plate 1 and a connecting structure 2. The connecting structure 2 includes a connector connected to the plate 1; adjacent floor elements 100 form a constraint force through the connector, and the adjacent floor elements 100 are connected to each other and can move together under the action of the constraint force. When a floor element 100 is subjected to a separation force that can overcome the constraint force, it separates from the adjacent floor element 100.
[0042] By setting connectors to create constraints between adjacent floor elements 100, they are combined and laid together on the walking area 200a and the configuration area 200b under the action of constraints. See Figures 8-9As shown, this allows users in the virtual scene to walk realistically within the walking area 200a in the real scene. When the floor element 100 overflowing the configuration area 200b is subjected to a separation force capable of overcoming constraints, it separates from the floor element 100 in the adjacent configuration area 200b, facilitating the splitting and reconfiguration of the floor element 100. This overcomes the limitations of physical space in the user's interaction process and enables omnidirectional movement within a plane.
[0043] The floor element of this application embodiment is applicable to the omnidirectional moving device of this application embodiment. See also... Figures 8-9 As shown, the device includes a base 200, floor elements 100, and a drive unit 300. A walking area 200a for interaction is formed on the base 200, and configuration areas 200b are respectively disposed outside the walking area 200a along a first direction and a second direction. Multiple floor elements 100 are laid on the walking area 200a and at least a portion of the configuration areas 200b along the first and second directions. The omnidirectional movement device 1000 achieves omnidirectional movement in a plane by decomposing the required displacement of the floor elements 100 into displacements in the first and second directions, and then driving the floor elements 100 to move the corresponding displacements along the first or second direction via the drive unit 300. However, the floor elements in this embodiment are not limited to this omnidirectional movement device 1000.
[0044] See Figures 8-9 As shown, since the drive unit 300 needs to drive the floor element 100 to move along the first direction or the second direction, the direct range of action of the drive unit 300 is the range of the walking area 200a. For the floor element 100 in the configuration area 200b outside the walking area 200a, there is an overlapping area in the first direction and the second direction. The drive unit 300 in the first direction and the second direction cannot exist in the overlapping area at the same time. Therefore, there is generally no drive unit 300 in the overlapping area. The floor element 100 in the overlapping area needs to move together with the adjacent floor element 100 under the constraint of the adjacent floor element 100. For example, if the direct movement distance of the floor element 100 driven by the drive unit 300 in the first direction is less than the side length of one floor element 100 (e.g., moving half the side length L of the floor element 100), and the floor element 100 without the drive unit 300 in the first direction does not produce any displacement, then the floor element 100 with the drive unit 300 and the floor element 100 without the drive unit 300 will be misaligned. If the floor element 100 needs to move in the second direction at this time, the floor element 100 entering the walking area 200a after passing through the configuration area 200b will experience misalignment and confusion. Furthermore, when the confused floor element 100 appears in the walking area 200a, changing the direction of movement of the floor element 100 again will cause movement interference between the floor element 100 in the walking area 200a and the configuration area 200b, preventing movement.
[0045] The connecting structure 2 can be a magnetic structure, Velcro, or adhesive bonding structure. Adjacent floor elements 100 are bound together by the connecting structure 2, forming a walking area 200a that allows users in the virtual scene to walk in the real scene. When a floor element 100 is subjected to a separation force, it separates from its adjacent floor elements 100. This separation force can be the weight of the floor element 100 itself or an external force applied to the floor element 100.
[0046] In one embodiment, see Figures 5-6 As shown, the separation force is the weight of the floor element 100 itself. When the floor element 100 overflows the configuration area 200b and needs to be separated, the overflowing floor element 100 generates a rotational torque relative to the rotational contact point under the action of gravity. The overflowing floor element 100 and the adjacent floor element 100 in the configuration area 200b rotate relative to each other and separate along the rotational separation contact point.
[0047] In one embodiment, see Figures 5-6 As shown, the thickness of plate 1 is H, and the distance between the center of the connector and plate 1 on one side along the thickness direction of plate 1 is 0.2H to 0.3H. When the overflowing floor element 100 and the adjacent floor element 100 in the configuration area 200b rotate relative to each other and separate along the contact point of rotational separation, the distance between the contact point of rotational separation and the constraint force of the connector is L2, and the constraint force is F2. Then, the torque of the constraint force that needs to be overcome to separate the floor element 100 is M2 = F2 × L2. That is to say, the smaller the distance of the constraint force from the separation contact point, i.e., the smaller L2, the smaller the torque of the constraint force that needs to be overcome to separate a single floor element 100 overflowing, and the easier it is for the floor element 100 to separate when overflowing. Considering the dimensions of the connector itself, the distance between the center of the connector and the plate 1 along the thickness direction is 0.2H to 0.3H, for example, 0.2H, 0.25H, or 0.3H. This allows the floor element 100 to overcome the constraint force and rotate away from the adjacent floor element 100 in the configuration area 200b under its own weight when overflowing. No additional equipment or manpower is required to separate the floor element 100, which facilitates the disassembly and reconfiguration of the floor element 100, improves the efficiency of the assembly, disassembly, and reconfiguration of the floor element 100, and saves manpower and resources.
[0048] In one embodiment, see Figures 1-2As shown, the connector is a magnet 21, and a mounting groove 1a is formed on the plate 1, with the magnet 21 located within the mounting groove 1a. By forming the mounting groove 1a on the plate 1 and placing the magnet 21 within it, adjacent floor elements 100 form a constraint force through the attraction between the magnets 21. Under the action of the attraction force of the magnets 21, adjacent floor elements 100 connect and combine to form a walking area 200a that allows users in the virtual scene to walk in the real scene. Multiple floor elements 100 are connected by attraction through the magnets 21, which is simple to operate and highly efficient. When a floor element 100 overflows the configuration area 200b and needs to be separated, it can be separated simply by overcoming the attraction force between the magnets 21. The separation of floor elements 100 will not damage the connection structure 2, meaning that the floor elements 100 can be connected and separated multiple times by attraction through the magnets 21, offering the advantages of convenient separation and multiple reuses.
[0049] In one embodiment, the connector is a magnet 21, which is disposed on the side of the plate 1, and adjacent floor elements 100 are connected by the attraction force between the magnets 21 disposed on the side.
[0050] Since the connector is a magnet 21, the attraction and attraction between magnets 21 require that the magnets 21 have opposite poles when they are close together. This necessitates that the polarity of the magnets 21 on the two sides of the two floor elements 100 approaching each other be determined and correctly installed during installation or splicing. This requirement is detrimental to the standardization of floor element 100 production. Furthermore, since the floor element 100 is a consumable part, this requirement to determine the polarity of the magnets 21 during use is detrimental to its replaceability. In industrial production, if the production of equipment with identical shapes requires attention to the detection, installation, and usage specifications of the magnetic poles, a series of technical requirements are usually imposed on production, storage, and transportation, which generally leads to a significant increase in costs. Therefore, the magnet 21 can be rotatably mounted in the mounting groove 1a, solving the problems of production process consistency and reduced requirements in transportation and use. The magnet 21 can be rotatably mounted in the mounting groove 1a via a rotating shaft connection or a flexible plastic suspension connection.
[0051] In one embodiment, see Figures 1-2 as well as Figure 7As shown, magnets 21 are rotatably disposed within mounting grooves 1a, allowing magnets 21 at corresponding positions on any two sides of adjacent floor elements 100 to attract each other. By rotatably disposing of magnets 21 within mounting grooves 1a, the magnetic poles of the magnets 21 disposed within the mounting grooves 1a can be changed as needed, so that different magnetic poles of magnets 21 face the side of the adjacent floor element 100 to which they are connected, and the adjacent floor elements 100 are connected to each other by the principle of attraction between opposite magnetic poles of magnets 21. By rotatably disposing of magnets 21 within mounting grooves 1a, it is not necessary to identify the different magnetic poles of magnets 21 in the floor elements 100 during installation; simply bringing the floor elements 100 close together allows magnets 21 to connect by rotating and attracting opposite magnetic poles. Rotating magnets 21 within mounting grooves 1a improves assembly efficiency and prevents the problem of magnets 21 failing to attract each other due to the same magnetic poles.
[0052] In one embodiment, see Figures 1-2 , Figure 4 as well as Figures 7-8 As shown, the connecting structure 2 also includes a connecting shaft 22, which is arranged along the length direction of the side of the plate 1 corresponding to the mounting groove 1a and connected to both ends of the mounting groove 1a. The magnet 21 is connected to the connecting shaft 22. The connecting shaft 22 is fixed at both ends of the mounting groove 1a, and the magnet 21 is rotatably mounted on the connecting shaft 22. By setting the connecting shaft 22 in the mounting groove 1a and fixing the connecting shaft 22 at both ends of the mounting groove 1a, and rotatably mounting the magnet 21 on the connecting shaft 22, the magnet 21 rotates through the connecting shaft 22. On the one hand, this improves assembly efficiency and prevents the floor element 100 from not being able to connect through the attraction between the magnets 21, but instead repelling each other, due to the inflexible rotation of the magnet 21. On the other hand, the rotation of the magnet 21 through the connecting shaft 22 can reduce the contact between the magnet 21 and the mounting groove 1a during the rotation process, preventing damage to the magnet 21 and thus improving the service life of the magnet 21.
[0053] In one embodiment, see Figures 1-2 , Figure 4 as well as Figures 7-8As shown, the connecting structure 2 also includes a connecting shaft 22, which is arranged along the length direction of the side of the plate 1 corresponding to the mounting groove 1a and connected to both ends of the mounting groove 1a. The magnet 21 is connected to the connecting shaft 22. The connecting shaft 22 is rotatably arranged at both ends of the mounting groove 1a, and the magnet 21 is rotatably arranged on the connecting shaft 22. By setting the connecting shaft 22 in the mounting groove 1a, and rotatably arranging the connecting shaft 22 at both ends of the mounting groove 1a, the magnet 21 is rotatably arranged on the connecting shaft 22. The rotation of the magnet 21 via the connecting shaft 22 not only enables the conversion of the magnetic poles of the magnet 21, but also enables the conversion of the magnetic poles of the magnet 21 via the rotation of the connecting shaft 22. This improves assembly efficiency, reduces contact between the magnet 21 and the mounting groove 1a during rotation, prevents damage to the magnet 21, and thus improves the service life of the magnet 21.
[0054] In one embodiment, see Figures 1-2 , Figure 4 as well as Figures 7-8 As shown, the connecting structure 2 also includes a connecting shaft 22, which is arranged along the length direction of the plate 1 corresponding to the mounting groove 1a and connected to both ends of the mounting groove 1a. The magnet 21 is connected to the connecting shaft 22. The connecting shaft 22 is rotatably arranged at both ends of the mounting groove 1a, and the magnet 21 is fixed on the connecting shaft 22. By setting the connecting shaft 22 in the mounting groove 1a, and rotatably arranged at both ends of the mounting groove 1a, and fixing the magnet 21 on the connecting shaft 22, the rotation of the connecting shaft 22 realizes the conversion of the magnetic poles of the magnet 21, preventing contact between the magnet 21 and the connecting shaft 22 and the mounting groove 1a during the rotation process, preventing damage to the magnet 21, and thus improving the service life of the magnet 21.
[0055] The connecting shaft 22 can be a single unit, rotatably mounted at both ends of the mounting groove 1a. The magnet 21 is fixed to the connecting shaft 22, and the magnet 21 changes magnetic poles as the connecting shaft 22 rotates. Alternatively, there can be two connecting shafts 22, each connected to one end of the magnet 21, rotatably mounted at both ends of the mounting groove 1a. Since the magnet 21 does not require holes and passes through the connecting shaft 22, it is directly connected to the end of the magnet 21, avoiding damage to the magnet 21, maintaining its integrity, and extending its service life.
[0056] In one embodiment, see Figures 1-2 As shown, the connecting structure 2 also includes an elastic element 23, which is connected to the connecting body to buffer the force on the connecting body along the length direction of the plate 1.
[0057] See Figure 3As shown, during the movement of the floor element 100 under force, the adsorption force between the connecting bodies in the floor element 100 causes nearby floor elements 100 that are not under force to move together. However, during the movement of the floor element 100, the vibration and impact between the floor element 100 under the driving force and the floor element 100 that is not under the driving force will bring a large instantaneous force, which can easily cause the constraint force between the connecting bodies to fail and separate.
[0058] See Figures 1-4 As shown, by setting the elastic element 23 to connect with the connecting body, the force on the connecting body along the length direction of the plate 1 is buffered. When a large instantaneous force occurs during the movement of the floor element 100, the connecting structure 2 of the floor element 100 can buffer the force on the connecting body along the length direction of the plate 1 through the elastic element 23, reducing the impact of the instantaneous force on the connecting body, producing a small-amplitude movement to adjust the force, and preventing the floor element 100 from separating due to a large instantaneous force. If a large instantaneous force directly drives the passive floor element 100 to move when adjacent floor elements 100 move, it may cause the two floor elements 100 to separate, resulting in confusion during movement in other directions. However, if the connecting body moves first to buffer the instantaneous force of the movement when the floor element 100 moves, and then drives the passive floor element 100 to move, the separation of the floor element 100 due to excessive instantaneous force is prevented.
[0059] Specifically, the floor element 100 under the driving force moves in the direction of the driving force at the instant it is driven, and has a certain relative displacement with the adjacent floor element 100 that is not under the driving force. At this time, the connecting bodies of the two floor elements 100 will move closer to each other under the action of the constraint force. That is, the connecting body of the floor element 100 under the driving force will exert a pressure or tension on the elastic element 23 in the opposite direction of the driving force under the force of the connecting body of the floor element 100 that is not under the driving force. At this time, a relative displacement occurs between the connecting body of the floor element 100 under the driving force and the floor element 100. The connecting body of the floor element 100 that is not under the driving force will exert a pressure or tension on the elastic element 23 in the same direction as the driving force under the force of the connecting body of the floor element 100 under the driving force. At this time, a relative displacement occurs between the connecting body of the floor element 100 that is not under the driving force and the floor element 100. By subjecting the floor element 100 to an instantaneous force, the connecting body of the floor element 100 under the driving force and the connecting body of the floor element 100 without the driving force are relatively displaced relative to each other and their corresponding floor elements 100. This keeps the connecting bodies within a certain distance range, thereby maintaining the constraint force between the connecting bodies and buffering the instantaneous force on the connecting bodies along the length direction of the plate 1. After the floor element 100 moves normally after being buffered by the instantaneous force, the relative displacement between the connecting body and the floor element 100 is restored under the action of the elastic element 23, that is, the connecting body returns to the corresponding position in the floor element 100.
[0060] See Figures 1-4 As shown, in one embodiment, elastic elements 23 are respectively provided at both ends of the connector. In this case, the connector of the floor element 100 subjected to the driving force will simultaneously exert a pressure and a tension opposite to the driving force on the elastic element 23 under the force of the connector of the floor element 100 not subjected to the driving force; conversely, the connector of the floor element 100 not subjected to the driving force will simultaneously exert a pressure and a tension in the same direction as the driving force on the elastic element 23 under the force of the connector of the floor element 100 subjected to the driving force. This facilitates restoration under the action of the elastic element 23, i.e., the connector returns to its corresponding position in the floor element 100; furthermore, when assembling the floor element 100, the arrangement direction of the floor element 100 does not need to be considered when setting elastic elements 23 at both ends of the connector, thus improving configuration efficiency.
[0061] Among them, the elastic element 23 can be rubber, plastic sheet, spring, etc.
[0062] See Figures 1-4As shown, in one embodiment, the connecting shaft 22 is arranged along the length direction of the side of the plate 1 corresponding to the mounting groove 1a. The connecting shaft 22 is fixed at both ends of the mounting groove 1a. The magnet 21 is rotatably arranged on the connecting shaft 22. Springs are provided between both ends of the magnet 21 and the mounting groove 1a.
[0063] In one embodiment, see Figures 1-4 As shown, at least one connecting structure 2 is provided along the length direction of each side of the plate 1. The number of connecting structures 2 provided along the length direction of each side of the plate 1 can be 1, 2, 3, 4 or more, so that when the floor element 100 under the driving force moves, it can carry the adjacent floor element 100 that is not under the driving force to move, and when the overflowing floor element 100 is subjected to a separation force that can overcome the constraint force, it separates from the adjacent floor element 100.
[0064] In one embodiment, two connecting structures 2 are symmetrically arranged at intervals along the length of each side of the plate 1. The arrangement of the two connecting structures 2 ensures that adjacent floor elements 100 form sufficient constraint force through the connecting body, and that when an overflowing floor element 100 is subjected to a separation force capable of overcoming the constraint force, it separates from the adjacent floor element 100. The symmetrical arrangement of the two connecting structures 2 at intervals increases the lateral shear force between the floor elements 100, effectively improving the stability of the connection between the floor elements 100.
[0065] In one embodiment, see Figure 3 As shown, the side length of plate 1 is L, and the distance between the center of the connecting body and the end of the edge of plate 1 is 0.15L to 0.3L. For example, it is 0.15L, 0.2L, 0.25L, or 0.3L. When two adjacent floor elements 100 are separated by force, the two floor elements 100 rotate relative to each other along the contact point of rotational separation. At this time, the distance from the rotation point to the point of application of the adsorption force between the connecting bodies is L1, and the constraint force is F1. Then, the torque of the constraint force that needs to be overcome to separate the floor elements 100 is M1 = F1 × L1. That is to say, the larger the distance between the two floor elements 100, the greater the distance of the constraint force from the separation contact point, that is, the larger L1 is, the greater the torque required for the separation of a single floor element 100 due to vibration, and the more stable the connection between the floor elements 100.
[0066] The vibration and impact during the movement of the floor element 100 can generate significant instantaneous forces. These instantaneous forces can easily cause the point of application of the constraint force of the magnet 21 to separate. Here, the constraint force is the attraction force between the magnets 21. Since the attraction force decreases significantly with the distance of application, vibration and impact can easily cause undesirable separation at the attraction point of the magnet 21. The attraction force of the magnet 21 is also the key force for maintaining the integrity of the floor element 100 in the walking area 200a and for driving the floor element 100 in the configuration area 200b to move laterally in the form of shear force. Once a vibration separation failure occurs, it may cause the entire equipment to malfunction.
[0067] In this embodiment, a magnet 21 is set between two adjacent floor elements 100 to attract each other. When the floor element 100 moves, the floor element 100 driven by the driven unit 300 moves the floor element 100 that is not directly driven by the driven unit 300, so as to achieve the effect of the floor elements 100 moving together as a whole.
[0068] In one embodiment, the projection of the plate 1 along its thickness direction is a parallelogram. A driving force acts on a row of floor elements 100, propelling the entire row of floor elements 100 in one direction in opposite directions as a "thrust." For example, if it is necessary to drive the floor elements 100 to move diagonally, such as moving them southeast, then driving forces in both northwest and southwest directions need to act simultaneously on the floor elements 100 to allow them to move in both directions at the same time. Setting the plate 1 as a parallelogram simplifies the process of splitting the floor elements 100 when they overflow and configuring them in the configuration area 200b. Setting the plate 1 as a rhombus further improves the efficiency of splitting the floor elements 100 when they overflow and in the configuration process.
[0069] In one embodiment, see Figure 1 As shown, the parallelogram is a square. Setting the plate 1 as a square further improves the efficiency of splitting the floor element 100 when it overflows and in the configuration process.
[0070] In one embodiment, the floor element 100 further includes a rubber patch or a rough-surfaced plastic patch disposed on each side of the board body 1. By providing structures such as rubber patches or rough-surfaced plastic patches on the sides of the board body 1 to increase side friction, or by surface-treating the sides of the board body 1 to increase side friction, the shear force between the floor elements 100 is improved, preventing the floor elements 100 from separating due to overcoming the constraint force under instantaneous force.
[0071] Another aspect of this application provides an omnidirectional mobile device, see [link to previous document]. Figures 8-9As shown, the system includes a base 200, a drive unit 300, and a floor element 100 as described above. The base 200 has a walking area 200a for interaction and a configuration area 200b respectively disposed outside the walking area 200a along a first direction and a second direction; a plurality of floor elements 100 are laid on the walking area 200a and at least a portion of the configuration area 200b along the first direction and the second direction; the drive unit 300 is configured to drive the floor elements 100 in the configuration area 200b to move the floor elements 100 in the walking area 200a, so that the floor elements 100 move along the first direction or along the second direction; the required displacement of the floor elements 100 is decomposed into displacements in the first direction and the second direction, and the drive unit 300 drives the floor elements 100 to move by the corresponding displacement along the first direction or the second direction, wherein the first direction and the second direction are not parallel.
[0072] The omnidirectional movement device provided in this application embodiment decomposes the required displacement of the floor element 100 into displacements in a first direction and a second direction, and then drives the floor element 100 to move the corresponding displacement along the first direction or the second direction through the driving unit 300, thereby achieving omnidirectional movement within a plane and overcoming the problem of physical space limitations in the user's interaction process. The omnidirectional movement device 1000 provided in this application embodiment has the advantages of simple structure and the ability to achieve omnidirectional movement within a plane.
[0073] See Figures 8-9 As shown, during the interaction, the user is located in the walking area 200a. Based on the turning, running, and walking prompts in different directions set in the virtual scene, the user is guided to walk realistically in the real scene. To ensure the user is not limited by physical space and remains within the walking area 200a regardless of their movement, the required displacement of the floor element 100 is decomposed into displacements in a first direction and a second direction. The driving unit 300 drives the floor element 100 to move the corresponding displacement along the first or second direction, achieving omnidirectional movement within the plane and providing the user with a realistic experience. Furthermore, the omnidirectional movement device 1000 provided in this embodiment has a simple structure and high safety performance.
[0074] Within the same plane, any displacement can be decomposed into displacements in any two non-parallel directions, therefore the first direction and the second direction are not parallel. The displacement corresponding to the floor element 100 is determined by the user's displacement, and the required displacement of the floor element 100 is decomposed into displacements in the first direction and the second direction.
[0075] Multiple floor elements 100 are laid along a first direction and a second direction on a walking area 200a and at least a portion of a placement area 200b. Wherein, if a floor element 100 needs to move in a certain direction, a floor element 100 is placed in the placement area 200b of that direction; if a floor element 100 does not need to move in that direction, a floor element 100 may be placed in the placement area 200b of that direction, or it may not be placed in the placement area 200b of that direction.
[0076] In one embodiment, see Figures 8-9 As shown, the omnidirectional moving device 1000 also includes a guide plate 400. One side of the guide plate 400 is connected to the outer side of the configuration area 200b, and the contact surface between the guide plate 400 and the floor element 100 is inclined. Overflowing floor elements 100 slide to the guide plate 400 under the pushing force of the floor elements 100 in the configuration area 200b. By setting the contact surface between the guide plate 400 and the floor element 100 to an inclined position, the gravity of the floor elements 100 overcomes the constraint force between the connecting bodies, thus separating the overflowing floor elements 100 from the adjacent floor elements 100. The inclination and surface friction coefficient of the guide plate 400 must be set corresponding to the constraint force between the connecting bodies to prevent the inclination from being too small or the friction coefficient from being too large, which would ultimately prevent the constraint force from being overcome and the parts from separating. The term "inclined" refers to the contact surface between the guide plate 400 and the floor element 100 being inclined outwards from bottom to top. The corresponding term "inclined" refers to the contact surface between the guide plate 400 and the floor element 100 being inclined inwards from bottom to top.
[0077] In one embodiment, see Figures 8-9 As shown, the omnidirectional moving device 1000 also includes a recycling pool 500, disposed outside the configuration area 200b, to receive floor elements 100 extruded from the configuration area 200b. One side of a guide plate 400 is connected to the outside of the configuration area 200b, and the other side extends towards the recycling pool 500, so that the floor elements 100 extruded from the configuration area 200b fall into the recycling pool 500 via the guide plate 400. The floor elements 100 extruded from the configuration area 200b are guided by the guide plate 400 before sliding into the recycling pool 500, ensuring that the floor elements 100 collected in the recycling pool 500 are neat and orderly. For example, the floor elements 100 extruded from the configuration area 200b may be in a row, connected in a row, and the floor elements 100 are guided by the guide plate 400 to prevent dispersion due to uneven force.
