[0026] 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.

[0027] like Figs. 1 to 4 As shown, a motion platform includes: a base 2, a slide 3, and a drive assembly 4. Two parallel linear guide rails 21 are fixed on the base 2; the slide 3 is slidably mounted on the linear guide rails 21; the drive assembly 4 includes a drive motor 41, a reducer 42, a first connecting rod 43, and a second connecting rod 44. The drive motor 41 is connected to the first connecting rod 43 through the reducer 42, and the second connecting rod 44 is pivotally connected to the first connecting rod 43. The other end of the second connecting rod 44 is pivotally connected to the lower part of the slide 3. The first connecting rod 43 is shorter than the second connecting rod 44. The drive motor 41 can drive the first connecting rod 43 to perform circular motion, and the drive motor 41 can rotate in both directions.

[0028] The drive motor 41, serving as the power source for the entire motion platform, has forward and reverse rotation capabilities, allowing for flexible adjustment of the rotation direction according to actual needs. The power output from the motor is first transmitted to the reducer 42, where it is reduced in speed and its torque is increased before being transmitted to the first connecting rod 43, causing it to perform circular motion. When the first connecting rod 43 rotates, the second connecting rod 44, which is pivotally connected to it, swings accordingly, thereby pushing the slide table 3 to slide left and right on the linear guide rail 21. Due to this unique mechanical structure, the movement of the slide table 3 on the linear guide rail 21 is not a simple, regular translation, but rather produces a more complex and variable-speed motion trajectory.

[0029] The drive motor 41 operates in various ways. It can continuously rotate in one direction. When the slide table 3 moves to the right and reaches a predetermined distance, the drive motor 41 can reverse to move the slide table 3 to the left. Alternatively, it can continue in circular motion. When the slide table 3 reaches its maximum left travel, the drive motor 41 continues to drive the first connecting rod 43, causing the slide table 3 to move to the right, and vice versa. In circular motion mode, the slide table 3 can move rapidly back and forth with varying speeds.

[0030] Compared to the overly regular translational motion generated by traditional motion platforms that rely on vibration motors or gear rack structures, this motion platform, with its unique drive component 4 design, enables the slide 3 to produce more complex motions that closely resemble the motion trajectories of objects in real-world scenarios, greatly enhancing the realism of motion simulation.

[0031] Specifically, the slide table 3 is equipped with two sliders 31 that cooperate with the linear guide rail 21, and the two sliders 31 are slidably mounted on the two linear guide rails 21 respectively.

[0032] Two sliders 31 are respectively installed on two parallel linear guides 21, which can provide more balanced support for the sliding table 3.

[0033] Specifically, the two linear guides 21 are fixed on the base 2 and are distributed on both sides of the sliding table 3 and close to the edges of the sliding table 3.

[0034] The two linear guides 21 are distributed on both sides of the sliding table 3 and close to the edges, which can build a very stable support structure for the sliding table 3.

[0035] Specifically, the mounting plate 22 is fixed on the base 2, and the mounting plate 22 is provided with a relief hole 221 for the first connecting rod 43 and the second connecting rod 44 to enter.

[0036] Specifically, the mounting plate 22 is fixed with a vertical mounting structure 23, and the speed reducer 42 is fixed on the mounting structure 23.

[0037] Specifically, the speed reducer 42 has an input shaft and an output shaft, and the output shaft and the input shaft are arranged vertically, the input shaft is connected with the driving motor 41, and the output shaft is fixedly connected with the first connecting rod 43.

[0038] Specifically, the driving motor 41 is a single-phase asynchronous motor.
