[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0025] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments, features, and technical solutions in the embodiments of this utility model can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] like Figures 1-5 As shown, this embodiment proposes a multimodal vehicle road condition simulation device, including a simulation platform 1. Several sets of simulation modules 2 are arranged at the inner end of the simulation platform 1. Each set of simulation modules 2 has multiple sets of moving wheels at its lower end. The outer end of the moving wheels has a sliding groove, which is embedded in the lower inner surface of the simulation platform 1. Each set of simulation modules 2 has a hollow groove 3 at its inner end. The inner end of the hollow groove 3 has a positioning sliding groove 4. The inner end of the positioning sliding groove 4 has a positioning rod 5 and a positioning shaft 6. The outer end of the positioning shaft 6 has a support frame 7. Both ends of the support frame 7 have linkage shafts 8. The lower end of the linkage shaft 8 has a movable linkage gear 9. The outer end of the linkage gear 9 has a positioning rack 10. The upper end of the linkage shaft 8 has an outer coupling shaft 11. The outer end of the outer coupling shaft 11 has an outer connecting slope 12. The lower end of the outer connecting slope 12 has a connecting rod, which slides in the sliding groove.

[0028] The simulation module 2 is equipped with simulation components that can simulate slippery road conditions in rainy or snowy weather, as well as scorching hot asphalt conditions in hot weather.

[0029] The slide moves along the moving wheel, the hollow groove 3 passes through the outer surfaces of the left and right ends of the simulation module 2, the hollow groove 3 is connected to the positioning slide 4, the inner end of the positioning slide 4 is slidably connected to the positioning shaft 6, and the positioning rod 5 is positioned on the outer surfaces of the upper and lower ends of the positioning shaft 6.

[0030] The casters, serving as the direct contact surface for simulation modules 2, ensure that each module 2 can move independently and smoothly on the simulation platform 1. The chute provides track-like guidance for this movement, ensuring stability and precision during the process. This combination not only enhances the overall flexibility of the simulation device but also allows for dynamic adjustments.

[0031] The hollow groove 3, connected to the positioning slide 4, forms a precise adjustment system. When the positioning rod 5 within the positioning slide 4 moves along the slide, it causes the positioning shaft 6 and the support frame 7 to undergo corresponding angular changes. These changes are further transmitted to the central shaft between the support frames 7, resulting in the overall structure unfolding or retracting. This ingenious design allows the simulation device to quickly switch between different operating conditions, meeting the simulation needs of various automotive driving scenarios.

[0032] The positioning shaft 6 is wrapped around the inner end of the support frame 7, and a central shaft is provided between the support frames 7. The central shaft is fixed in the center of the simulation stage 1.

[0033] The ingenious combination of the positioning shaft 6 and the support frame 7 forms a stable support system. The positioning shaft 6, as a load-bearing component, bears the external force and distributes it evenly to the support frame 7. The central shaft positioned between the support frames 7 ensures the rigidity of the overall frame, maintaining good stability even during movement. This design ensures that the device can operate safely and reliably even under simulated extreme road conditions, avoiding safety hazards caused by structural instability.

[0034] The positioning rod 5 slides along the positioning groove 4, and the two ends of the support rod are fixedly connected to the linkage shaft 8.

[0035] A linkage motor is provided between the linkage shaft 8 and the linkage gear 9. The linkage motor is embedded in the lower inner surface of the linkage shaft 8. The movable end of the linkage motor is fixedly connected to the linkage gear 9. The outer end of the linkage gear 9 is meshed with the positioning rack 10.

[0036] The linkage shaft 8 and the linkage gear 9 form a highly efficient transmission system. The linkage motor drives the linkage gear 9 on the linkage shaft 8 to rotate, which in turn drives the positioning rack 10 to move, thus achieving coordinated operation of the entire system. The connection point between the linkage shaft 8 and the external coupling shaft 11 makes the power transmission path more flexible and adaptable to the power requirements under complex working conditions.

[0037] The outer end of the positioning rack 10 is provided with an arc-shaped groove, which is embedded in the inner end of the simulation table 1. The upper end of the linkage shaft 8 is movably connected to the outer coupling shaft 11. The outer end of the outer coupling shaft 11 is fixedly connected to the outer coupling slope 12. The lower end of the outer coupling slope 12 is fixedly connected to the connecting rod. The connecting rod slides along the inside and outside of the groove.

[0038] The meshing action between the positioning rack 10 and the linkage gear 9 is the core of achieving precise control in the entire system. Through the precise rotation of the linkage gear 9, the positioning rack 10 moves accurately, thereby changing the angle of the support frame 7 and ultimately realizing the change in the spacing of the simulation modules 2. The coordinated work of the positioning rack 10 and the linkage gear 9 ensures the smoothness and precision of every action during the simulation process, laying a solid foundation for achieving realistic simulation of various road conditions.

[0039] The outer coupling 11 and the connecting rod together form an effective dynamic feedback link. Under the action of the outer slope 12, the lifting and lowering of the outer coupling 11 drives the connecting rod to move horizontally along the slide, which can not only respond to external forces in time, but also maintain its own position under specific working conditions, thus playing a fixed anchoring role.

[0040] When this application is used, during the debugging of vehicle road conditions, firstly, the linkage gear 9 at the lower end of the linkage shaft 8 is rotated by four sets of linkage motors. The linkage gear 9 meshes with the positioning rack 10 in the arc groove and moves, causing the included angle between the support frame 7 to decrease. This pushes the outer ramp 12 connected to the upper end of the outer coupling shaft 11 to move outward under the limit of the connecting rod. At the same time, the space restriction of the hollow groove 3 and slide groove inside each set of simulation modules 2 pushes the positioning shaft 6 and positioning rod 5 to move in a limited manner, increasing the distance between the two sets of simulation modules 2. At the same time, a triangular bracket is provided at the lower end of each set of simulation modules 2 to ensure the support stability of each set of simulation modules 2. By adjusting the distance between the two sets of simulation modules 2, the driving conditions of the vehicle can be simulated well.

[0041] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
