[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The various specific technical features described in the specific embodiments may be combined in any suitable manner, unless they are inconsistent. For example, different embodiments and technical solutions may be formed by combining different specific technical features. To avoid unnecessary repetition, the various possible combinations of the specific technical features in the present invention will not be described separately.

[0029] In the following description, the terms "first, second, ..." are used solely to distinguish different objects and do not imply any similarities or connections between the objects. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to directions during normal use. The directions "left" and "right" refer to the left-right directions shown in the corresponding schematic diagrams, which may or may not be the left-right directions during normal use.

[0030] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0031] The present invention provides a floor element mobile device that can be applied to interactive scenarios such as virtual reality (VR), augmented reality (AR), mixed reality (MR), and extended reality (XR). It should be noted that the application scenario type of the present invention does not limit the mobile device of the present invention.

[0032] First, the movement principle of the floor element movement device is briefly explained. In a virtual reality interactive experience, users desire to simulate the experience of unlimited space within a limited space. This embodiment of the present invention utilizes a spliced ​​configuration of multiple floor elements. Users walk on these moving floor elements, allowing them to move while maintaining the same floor position. This simulates unlimited movement within a limited space, providing a more realistic immersive experience.

[0033] The following describes the specific structure of the floor element moving device according to the embodiment of the present invention. Figure 1 As shown, the floor element moving device of the embodiment of the present invention comprises a base 1, a floor element 2 and a driving mechanism 3. The first surface of the base 1 is a platform for placing the floor element 2. Figure 1The upper surface of the base 1 is shown. A plurality of floor elements 2 can be spliced ​​together to form a floor, that is, the floor elements 2 can be understood as components for forming a floor. The shapes and structures of the plurality of floor elements 2 can be the same or different. They are spliced ​​together to form a floor located on the first surface. When the shape and area of ​​the first surface of the base 1 are fixed, the shape and area of ​​the floor located on the first surface are also unchanged. It should be noted that the embodiment of the present invention does not limit the specific shape of the floor element 2. The floor element 2 can be set to a square or other shape that is easy to splice and detach. The driving mechanism 3 is provided at the edge of the base 1. Specifically, the base 1 has a boundary in contact with the external environment or other components. A certain area including the boundary can be called an edge. In other words, the edge can refer not only to the boundary of the base 1, but also to an area close to the boundary. As long as the driving device can drive the floor element adjacent to the boundary of the base 1 to move relative to the first surface within the area, the area can be considered to be the edge of the base 1. There can be one or more driving mechanisms 3, as described below. Figure 1 Take the driving mechanism on the right side of the middle as an example to explain. Figure 1 The driving mechanism 3 on the right side of the middle works, and the floor element 2 at the right edge of the base 1 pushes the adjacent floor element in the base 1 to move ( Figure 1 Move from right to left along the x-axis direction), so that the floor element 2 on the other edge of the base 1 opposite to the one edge overflows ( Figure 1 The floor element on the left overflows, and the overflowing floor element is disconnected from the floor on base 1. When a user walks on the floor, the driving mechanism drives the floor element in the direction opposite to the user's movement, making the user feel continuous movement on the floor, while the floor on the base as a whole does not change or move. This allows the user to experience moving in an infinite space, even though the floor actually occupies a limited area and space.

[0034] The floor element moving device in the embodiment of the present invention forms a floor on the first surface of the base through movable floor elements. During the virtual reality interaction process, the user walks on the floor, and the driving mechanism moves the floor elements according to the walking direction, thereby achieving the movement of the floor elements while keeping the position of the floor unchanged, thereby simulating the function of infinite movement in a limited space, improving the user's sense of movement realism, realizing real walking in the virtual scene, and further improving the experience effect of the interactive device.

[0035] In some embodiments, as Figure 2As shown, the driving mechanism 3 includes a driving roller 31, which is adjacent to the floor element 2. It should be noted that adjacent means that the driving roller 31 can be in contact with the floor element 2 or set at a certain gap, but cannot be separated by other physical components; and the driving roller 31 is set at the edge of the base 1 and close to the floor element 2. The driving roller 31 can rotate around its axis to press and drive the floor element 2 to move along the first direction within the first surface. Specifically, during the rotation of the driving roller 31, the rotating surface of the driving roller 31 presses against the surface of the floor element 2 (refer to Figure 1 The driving roller 31 rotates and applies a rotational force to the surface of the floor element 2. The friction between the driving roller 31 and the floor element 2 is greater than the friction between the floor element 2 and the first surface of the base 1. The driving roller 31 can drive the floor element 2 to move relative to the first surface of the base 1. Figure 2 shown to the left) and the direction of the axis around which the driving roller 31 rotates ( Figure 2 The driving roller is used to press the floor elements against the first surface. The driving roller can be flexibly positioned so as not to block the recovery area of ​​the floor elements that overflow from the edge of the base, thus saving space.

[0036] In another embodiment, a drive roller may be disposed on the bottom surface of the floor element. The floor element rests against the surface of the drive roller due to gravity. When the drive roller rotates, a driving force is applied to the bottom surface of the floor element, and the contact friction between the drive roller and the bottom surface of the floor element drives the floor element relative to the base. In this embodiment of the present invention, the drive roller drives the floor element, utilizing the contact friction between the drive roller surface and the floor element surface to achieve movement. Simply positioning the drive roller at the edge of the base allows the floor element to be driven in one direction, resulting in a simple structure and convenient drive.

[0037] In some embodiments, as Figure 1 As shown, there are at least two driving rollers 31, and the axis directions of two adjacent driving rollers 31 are at a preset angle. It should be noted that adjacent means that the two driving rollers 31 are close to each other, and there may be a gap at the closest point but no other physical parts can be separated, for example, Figure 1The right drive roller is shown as being adjacent to the front drive roller, while the right drive roller is not adjacent to the left drive roller. The term "preset angle" refers to the angle between the axes of the drive rollers. The angle in this embodiment of the present invention is not limited to the number of drive rollers 31 provided. In one embodiment, the angle can be set to be greater than 45°, or even substantially 90°. This "preset angle" is defined to account for manufacturing and installation errors and is not strictly 90°. A predefined angle of substantially 90° is considered sufficient if the axes of the two drive rollers are approximately perpendicular. In other embodiments, four drive rollers 31 can be provided, forming a quadrilateral region with the base 1 at least partially disposed within this quadrilateral region. The four drive rollers 31 control the driving directions of the floor element 2 on the base 1 in four directions, respectively. By independently or jointly controlling the four drive rollers, the floor element can be driven in different directions, thereby providing a user with a different directional motion experience.

[0038] It should be noted that the number of driving rollers 31 in the embodiment of the present invention does not limit the shape of the base 1. The first surface of the base 1 can be set to a rectangular, square, circular or other shape. The following description takes the case where the first surface of the base 1 is set to a quadrilateral as an example. The axis of the driving roller 31 is parallel to the boundary of the base 1. When the four driving rollers 31 set at the edge of the base 1 work independently, they can drive the floor element to move in four directions respectively ( Figure 1 In the plane surrounded by the xy axis, the four directions are referred to as the positive directions below. When two adjacent driving rollers 31 work together, the floor element 2 receives driving forces in two different positive directions, which can be combined to form a direction. Figure 1 The driving force in the oblique direction (hereinafter referred to as non-positive direction) with an acute angle to the positive direction is used to drive the floor element 2 to move in the non-positive direction (for example Figure 1 Alternatively, the rotational speed of the cooperating drive rollers may be adjusted to create a speed difference between adjacent drive rollers, thereby controlling the direction of movement of the floor element to shift in a specified direction. Alternatively, the number of drive rollers may be greater than four, such as six or eight. In embodiments of the present invention, the precision of the direction of movement of the floor element can be adjusted by adjusting the number of drive rollers.

[0039] In some embodiments, the first surface of the base 1 is square, such as Figure 3As shown, the driving rollers 31 are provided in two groups, and each group of driving rollers 31 includes two driving rollers 31 with parallel axis extension directions, and the axis extension directions of the two groups of driving rollers 31 are perpendicular. Specifically, the axis directions of the left and right driving rollers are in the up-down direction, and the axis directions of the upper and lower driving rollers are in the left-right direction, so the axis directions of the two groups of driving rollers are perpendicular. In the embodiment of the present invention, by providing a driving roller on each side of the base, it is possible to achieve four positive azimuth drives, and simultaneously drive two adjacent driving rollers to achieve non-positive azimuth drives, refer to Figure 4 , showing a schematic diagram of the force of two adjacent driving rollers driving the floor elements together. The embodiment of the present invention is not limited to the shape of the above-mentioned base. Specifically, the base can be set to be rectangular, the driving rollers form a rectangular area, and the floor elements in the square area are spliced ​​to form a floor. The four driving rollers can respectively drive the floor elements to the east, south, west, and north ( Figure 3 The embodiment of the present invention provides two sets of drive rollers extending in perpendicular directions and parallel directions within the same set, enabling simulation of movement of floor elements in various directions using a relatively simple arrangement. While experiencing the interaction between virtual and real life, the user moves on the floor, and the drive rollers move the floor elements according to the user's walking direction. While ensuring that the user moves within the floor area enclosed by the drive rollers, the user can also experience a realistic walking experience in multiple directions, simulating unlimited movement within a limited space and providing a deeply immersive experience.

[0040] In some embodiments, as Figure 5As shown, the surface of the drive roller 31 has multiple mounting grooves 31a extending along its axis. It should be noted that the mounting grooves 31a are recessed downward from the surface of the drive roller 31. The mounting grooves 31a extend parallel to the direction of extension of the drive roller 31, both in the direction of the drive roller's axis. The multiple mounting grooves 31a are spaced apart circumferentially. Spacing means that the mounting grooves 31a are spaced apart circumferentially from each other, and the spacing between the mounting grooves 31a can be equal. The drive mechanism also includes a drive wheel 33 rotatably disposed within the mounting groove 31a. Optionally, multiple drive wheels 33 can be spaced apart within the same mounting groove 31a along the axis of the drive roller 31. The drive wheel 33 can be flush with or protrude from the surface of the drive roller 31. Flush means that the rotating surface of the drive wheel 33 is in the same plane as the surface of the drive roller 31, and protruding means that at least a portion of the drive wheel 33 extends from the mounting groove 31a to the outside of the drive roller 31. The axis of the drive wheel 33 is perpendicular to the axis of the drive roller 31. The drive roller 31 can rotate about its own axis, and the drive wheel 33 can also rotate about its own axis. Therefore, the directions of the rotation axes of the drive wheel 33 and the drive roller 31 are perpendicular to each other. It should be noted that the perpendicularity mentioned above takes into account the accuracy of processing and installation, and does not require that the angle between the two axes is an absolute 90°. A certain degree of error is allowed.

[0041] Combine Figure 3 and Figure 4 As shown below, the driving floor element Figure 3 Let’s take the upper left middle movement as an example to explain. Figure 4 The diagram shows the force applied to the floor element when it moves to the upper left relative to the first surface. When the axes of the two adjacent driving rollers are perpendicular, Figure 4 The right driving roller and the lower driving roller drive the floor element 2 to move at the same time. The floor element 2 is driven to the left by the driving force F E At the same time, the downward friction force f S The floor element is driven by the upward driving force F of the driving roller below. S At the same time, the rightward friction force f E ; Due to the driving force F E and F S The net force is greater than the friction force f E and f S The resultant force, driving force F E and F S The resultant force can overcome the friction force f E and f S The resultant force drives the floor element to move.

[0042] Reference Figure 5By providing a plurality of mounting grooves 31a extending along the axial direction on the surface of the driving roller 31, the driving wheel 33 is rotatably arranged in the mounting groove 31a. The axis of the driving wheel 33 is perpendicular to the axis of the driving roller 31, and the rotation direction of the driving wheel 33 is perpendicular to the rotation direction of the driving roller 31. In the axial direction of the driving roller, the relative movement between the floor element and the driving roller axial direction changes from sliding to rolling. When the right driving roller drives the floor element to move toward the left, the lower driving roller applies an upward driving force F S To the floor element, the upward driving force F S and the leftward driving force F E The friction force f acting on the floor element S and friction force f E As the angle between the two driving rollers decreases, the resultant force of the two friction forces also decreases, and the driving force for providing the floor element movement increases, thereby improving the driving efficiency of the two driving rollers set at a certain angle. At the same time, the use of rolling friction can extend the service life of the driving roller.

[0043] In some embodiments, reference Figure 1 The floor element moving device further includes a responsive pressing mechanism 4, which is connected to the drive roller 31. It should be noted that the connection refers to the responsive pressing mechanism 4 being directly or indirectly connected to the drive roller 31. The responsive pressing mechanism 4 is used to drive the drive roller 31 to press against the floor element 2 when the drive mechanism 3 is in the working state. Pressing means that the drive roller 31 presses against the surface of the floor element 2 and applies a certain force to the floor element 2, thereby increasing the friction between the drive roller 31 and the floor element 2, thereby improving the transmission efficiency of the drive roller 31. When the drive mechanism is not in the working state, the force applied by the drive roller to press against the floor element is less than the force applied when the drive mechanism is in the working state, or there is no direct contact between the drive roller and the floor element. In this case, the drive roller has no frictional effect on the movement of the floor element, and thus will not interfere with the drive of the floor element by another drive mechanism.

[0044] In some embodiments, the driving mechanism 3 further includes a driving member, which includes but is not limited to a driving motor such as a forward and reverse motor, and the driving member is used to drive the driving roller 31 to rotate; Figure 6 As shown, the response pressing mechanism 4 includes a transmission member 41 and a return member 42. The transmission member 41 connects the driving member and the driving roller 31, and the connection method is not limited to gears and belts. When the driving member is in the working state, the transmission member 41 drives the driving roller 31 to move toward the direction close to the floor element under the action of the driving member ( Figure 6In this state, the return member 42 abuts against the driving roller 31 and the driving roller 31 presses the floor element, so that the floor element can be driven to move under the driving action of the driving roller 31; in the non-working state of the driving member, there is no driving force on the transmission member 41, then the return member 42 will drive the driving roller 31 to move away from the floor element under the action of the restoring force ( Figure 6 In the upward direction), the driving roller 31 no longer presses against the floor element, and the corresponding driving roller cannot drive the floor element to move. Optionally, the return member 42 can be set as a spring. In the embodiment of the present invention, by setting the responsive downward pressure mechanism as a transmission member and a return member, when the driving member is in the working state, the driving roller presses against the floor element to realize the transmission of the floor element, thereby driving the floor element to move; when the driving member is in the non-working state, the driving roller is away from the floor element and does not drive the floor element to move and does not affect the movement of the floor element by other driving rollers; therefore, when multiple driving rollers are provided, the friction of the floor element relative to other driving rollers will not be generated due to the movement of the floor element by one driving roller, thereby improving the driving efficiency.

[0045] In some embodiments, as Figure 6 As shown, the base 1 is provided with a movable groove 11, and the return member 42 is provided in the movable groove 11. The movable groove 11 has a space for the end of the driving roller to move. Specifically, the end of the driving roller 31 is provided in the movable groove 11 and abuts against the return member 42. Under the driving force of the driving member, the end of the driving roller 31 moves in the movable groove 11 ( Figure 6 The driving roller 31 squeezes the restoring member 42, and the entire driving roller 31 presses against the floor element and rotates to drive the floor element to move; when the driving member is not in operation, the restoring force of the restoring member 42 acts on the end of the driving roller, causing the driving roller 31 to make a restoring motion along the movable groove 11 ( Figure 6 The movable groove and the restoring member are configured to control the movement of the drive roller via the end of the drive roller. This provides a simple structural design, limits the travel range of the drive roller, and improves the stability of the drive roller's movement.

[0046] In some embodiments, as Figure 7As shown, the output end of the driving member 32 is provided with an output gear 32a, and the driving roller 31 is provided with a movable gear 31b. The transmission member 41 includes a transmission shaft 41a, a first transmission gear 41b, and a second transmission gear 41c. The first transmission gear 41b is fixed to the transmission shaft 41a and meshes with the output gear 32a. The second transmission gear 41c is fixed to the transmission shaft 41a and meshes with the movable gear 31b. The driving member 32 can drive the output gear 32a to rotate, and the output gear 32a drives the first transmission gear 41b to rotate, which in turn drives the transmission shaft 41a to rotate. The transmission shaft 41a drives the second transmission gear 41c, which is located on the transmission shaft 41a, to rotate. Since the movable gear 31b meshes with the second transmission gear 41c, the second transmission gear 41c drives the movable gear 31b to rotate. The gear transmission method is used to transmit the driving force of the driving member step by step to the driving roller, which has accurate transmission accuracy and high transmission efficiency.

[0047] In some embodiments, as Figure 7 As shown, along the extension direction of the transmission shaft 41a, the second transmission gear 41c is arranged on both sides of the first transmission gear 41b. The first transmission gear 41b and the second transmission gear 41c are both fixedly arranged in the extension direction of the transmission shaft 41a. The first transmission gear 41b is engaged with the output gear 32a, and the second transmission gear 41c is engaged with the movable gear 31b. There are two second transmission gears 41c, and the two second transmission gears 41c are arranged on both sides of the first transmission gear 41b ( Figure 7 Only one second transmission gear 41c is shown; the other second transmission gear 41c is located on the other side of the first transmission gear 41b. When the driving member 32 is in operation, it simultaneously drives the movement of both second transmission gears 41c, allowing the pressure from both ends of the drive roller 31 to be applied simultaneously to both ends of the floor element, reducing the problem of low transmission efficiency caused by uneven force on the floor element. Specifically, the first transmission gear 41b is positioned in the middle of the transmission shaft 41a, and the second transmission gears 41c are symmetrically positioned at both ends of the first transmission gear 41b. This improves the synchronization of the downward pressure of the floor element by the two ends of the drive roller, thereby enhancing transmission efficiency.

[0048] In some embodiments, multiple floor elements are connected by magnetic attraction. Figure 1 As shown, the driving roller 31 is arranged at the edge of the base 1. The floor elements 2 at the corresponding edge positions that are in direct contact with the driving roller 31 are moved by the friction force of the driving roller 31. However, there may be floor elements 2 that are not in direct contact with the driving roller 31. For example, Figure 1For example, the vertical direction is columns, and the horizontal direction is rows. Floor elements 2 located at the edges of the columns and rows at the ends of the base 1 may not be in direct contact with the drive roller 31. Consequently, these floor elements not in direct contact with the drive roller 31 cannot be directly driven by the friction of the floor elements to move. In this embodiment of the present invention, by magnetically connecting multiple floor elements, these floor elements not in direct contact with the drive roller 31 can be driven to move by other floor elements. The magnetic attraction of the floor elements themselves enables the drive roller to drive the floor elements in the same row or column, achieving consistent movement.
