[0002] In the field of immersive entertainment devices, the gameplay platform, as a core component integrating motion capture, mechanical feedback and multimodal interaction, has been widely used in virtual reality games, motion-sensing competitions and rehabilitation training.

[0003] Traditional play platforms employ hinged linkages, lead screws and nuts, or fixed rack and pinion transmission structures, with the transmission components fixed to the platform via rigid connectors such as bolts and bearings. During high-frequency, high-impact interactions (such as jumping and pushing), stress concentration at the connection points can easily lead to fatigue cracks, causing the structure to loosen or jam.

[0023] 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.

[0024] like Figure 1-6 As shown, the multimodal sensing seesaw device of this utility model includes a support assembly, an adjustment mechanism, a sliding assembly, and a sensing mechanism. The adjustment mechanism is located on the inner wall of the support assembly and is used to adjust the support assembly. The sliding assembly is located on the inner wall of the support assembly to facilitate the operation of the adjustment mechanism. The sensing mechanism is located on the inner wall of the support assembly. The adjustment mechanism includes a drive motor 21 and a transmission shaft 22. The drive motor 21 is located at one end of the support assembly, and the transmission shaft 22 is located at one end of the drive motor 21. A transmission gear 23 extends outward from the transmission shaft 22 and is located on the inner wall of the transmission shaft 22. A transmission rack 24 extends outward from the transmission gear 23 and is located at one end of the adjustment mechanism.

[0025] Specifically, after the drive motor 21 starts, its output torque is transmitted to the transmission gear 23 through the transmission shaft 22. The meshing of the gear and the transmission rack 24 converts the rotational motion into the linear reciprocating motion of the rack. One end of the push rod 201 is fixed to the rack, and the other end applies thrust to the edge of the swing platform 102 or the movable shaft 210 through the push block 202 (the upper surface protrusion), thereby realizing the lifting and lowering drive of the platform.

[0026] It also includes a push rod 201, which is located at one end of the sliding assembly. The push rod 201 extends outward to provide a push block 202 for pushing the support assembly. The push block 202 is located on the upper surface of the push rod 201, and the transmission rack 24 is located at one end of the push rod 201.

[0027] Specifically, the drive motor 21 is mounted on one end of the fixed plate 14, and drives the transmission shaft 22 to rotate when started. The transmission gear 23 on the inner side of the transmission shaft 22 meshes with the transmission rack 24 at one end of the adjustment mechanism, converting the rotational motion of the motor into the linear motion of the rack. The transmission rack 24 is connected to the push rod 201, and one end of the push rod 201 is provided with a push block 202, which is used to apply pushing or pulling force to the support assembly, thereby realizing the adjustment of the support assembly.

[0028] It also includes a movable shaft 210, which is located on the inner wall of the support assembly. The movable shaft 210 extends outward and is provided with movable blocks 211. Two movable blocks 211 are located on the inner wall of the movable shaft 210 to facilitate the rotation of the support assembly.

[0029] Specifically, when the adjustment mechanism pushes the support component, the movable shaft 210 and the movable block 211 can drive the rocking platform 102 to rotate, thereby changing the angle and position of the support component to adapt to different usage requirements.

[0030] The sliding assembly includes a sliding guide rail 31 and a slider 32. The sliding guide rail 31 is formed on the inner side wall of the support assembly, and the slider 32 is located on the inner side wall of the sliding guide rail 31 and can reciprocate vertically relative to the sliding guide rail 31. The push rod 201 is located at one end of the slider 32.

[0031] Specifically, the sliding guide rail 31 is vertically positioned inside the support plate 13, and the slider 32 reciprocates vertically within the guide rail under the pull of the push rod 201. The clearance fit between the guide rail and the slider 32 (such as a ball bearing or lubrication design) ensures that the push rod 201 moves only linearly along the guide rail direction, avoiding lateral deviation and improving motion accuracy and system stability.

[0032] The sensing mechanism includes a photosensitive eye 41, which is located on the inner sidewall of the support assembly. Multiple photosensitive eyes 41 are provided and spaced apart.

[0033] Specifically, the photosensitive eye 41 is installed on the inner wall of the swing platform 102 to detect changes in the position of the ball.

[0034] It also includes a sensing slice 401, a low-position photocell 402, and a high-position photocell 403. The sensing slice 401 is located on one side wall of the transmission gear, the low-position photocell 402 is located at one end of the support assembly, and the high-position photocell 403 is located at one end of the support assembly.

[0035] Specifically, the sensing slice 401 on the side wall of the transmission gear 23 rotates with the gear. When the slice blocks the high-position photodetector 403, the control system (not shown) immediately sends a braking command to the drive motor 21, causing it to enter a stationary state with holding torque. This state is maintained for a preset time interval (recommended value: 3-5 seconds) to ensure stable material reception. After the stationary timeout ends, the drive motor 21 resumes forward rotation. When the slice blocks the low-position photodetector 402, the control system (not shown) immediately sends a braking command to the drive motor 21, causing it to enter a stationary state with holding torque. After the adjustment mechanism stops, the rocker unloading device and push rod assembly naturally fall to their reset position under gravity through a precisely designed counterweight balancing mechanism. The array of sensing photodetectors 41 inside the rocker platform 102 monitors its tilt angle and load distribution in real time. The center of gravity position is calculated through the difference in photodetector signals, and the motor speed or start / stop threshold is dynamically adjusted to achieve closed-loop control.

[0036] The support assembly includes a base 11 and a worktable 12. The worktable 12 is located on the upper surface of the base 11. A support plate 13 extends outward from the worktable 12 and is located at one end of the worktable 12. A fixing plate 14 extends outward from the support plate 13 and is located at one end of the support plate 13. A drive motor 21 is located at one end of the fixing plate 14. A low-position photoelectric sensor 402 is located at one end of the fixing plate 14. A high-position photoelectric sensor 403 is located at one end of the fixing plate 14. A sliding guide rail 31 is located on the inner side wall of the support plate 13.

[0037] Specifically, the support assembly, which serves as the foundation of the entire device, includes the base 11 and the worktable 12, providing stable support for other components. The support plate 13, the fixing plate 14, and the support base 101 extending from the worktable 12 provide mounting positions for the adjustment mechanism, the sliding assembly, and the sensing mechanism.

[0038] A support base 101 extends outward from the worktable 12, and the support base 101 is vertically mounted on the worktable 12. The movable shaft 210 is located on the inner sidewall of the support base 101; and

[0039] A swing platform 102 is located on the upper surface of the movable block 211, and a sensor photoelectric eye 41 is located on the inner sidewall of the swing platform 102.

[0040] Specifically, the device uses base 11 and worktable 12 as its base, with support plate 13 and fixed plate 14 extending vertically to form a frame. The swing platform 102 is suspended from support base 101 via movable shaft 210, forming a seesaw structure that can rotate around the shaft.

[0041] The worktable 12 extends inward to form a limiting groove 1, which is located on the inner side wall of the worktable 12 and is used to limit the adjustment mechanism.

[0042] Specifically, the limiting groove 1 on the inner side of the worktable 12 restricts the stroke of the transmission rack 24 to prevent the push rod 201 from extending excessively and causing mechanical jamming.

[0043] By optimizing the transmission and support structure, particularly through the design of the movable shaft 210, movable block 211, and sliding components, stress is effectively dispersed, reducing stress concentration and significantly improving the overall stability and durability of the device, thus extending its service life. The design of the adjustment mechanism allows for flexible adjustment according to actual usage requirements. The cooperation between the drive motor 21 and the transmission shaft 22, and the meshing of the transmission gear 23 and the transmission rack 24, achieve precise power transmission and position control. The placement of the push rod 201 and the push block 202 further enhances the intuitiveness and convenience of adjustment, allowing users to easily adjust the device to its optimal working state.
