[0002] In the field of vehicle engineering, especially in the stability testing of ATV and UTV two vehicle models, it is crucial to ensure the stability and safety of vehicles. Vehicle stability testing is one of the key steps to evaluate vehicle performance, improve design and ensure safe operation. Traditional vehicle stability testing methods usually rely on actual road testing or subjective evaluation in a simulated driving environment. This method not only consumes time and effort, but also makes it difficult to accurately control the testing conditions, resulting in poor consistency and repeatability of the results.

Existing vehicle stability testing platforms mostly use fixed-angle inclination or simple hydraulic systems to simulate different road conditions. However, many existing testing platforms can only provide limited angle changes, and the small angle for ATV and UTV cannot fully simulate various complex road conditions that may be encountered in reality.

[0025] The utility model will be described further in detail in combination with the drawings and specific implementation manners: refer to Figures 1-9 The test platform for vehicle stability test comprises a mounting base 1 and a placing platform 2, wherein the placing platform 2 is rotatably connected to one side of the mounting base 1; specifically, the mounting base 1 comprises a first side rod 12 and a second side rod 13 located on the same side, and the first side rod 12 is higher than the second side rod 13.

[0026] The placing platform 2 is rotatable outside the first side rod 12, and the placing platform 2 is rotatably connected through a plurality of hinges.

[0027] In order to realize that the placing platform 2 can rotate along the hinges, a first lifting structure 3 and a second lifting structure 4 are arranged inside the mounting base 1, and the placing platform 2 can realize large-angle rotation and accurate control through the cooperation of the two lifting structures.

[0028] Specifically, the first lifting structure 3 is a bottom lifting structure, and the second lifting structure 4 is located above the first lifting structure 3; therefore, the first structure comprises a first hydraulic cylinder 5 and a plurality of first connecting rods 6 rotatably connected to each other, and the second lifting structure 4 comprises a second hydraulic cylinder 7 and a plurality of second connecting rods 8 rotatably connected to each other.

[0029] Furthermore, the first hydraulic cylinder 5 is connected to the second side rod 13 at the bottom, and the first hydraulic cylinder 5 is rotatably connected to the second side rod 13; meanwhile, the other side of the first hydraulic cylinder 5 is rotatably connected to the connection between the first connecting rods 6; the first connecting rod 6 located below is rotatably connected to the third side rod 14 of the mounting base 1, and the first connecting rod 6 located above is rotatably connected to the inside of the placing platform 2; that is, a connecting piece 9 is arranged inside the placing platform 2, the first connecting rod 6 is rotatably connected to the connecting piece 9, the first connecting rod 6 is rotatably connected to the mounting block, and the mounting block is arranged away from the hinge;

[0030] When the first hydraulic cylinder 5 is started, the included angle between the first connecting rods 6 becomes larger, which in turn causes the upper first connecting rod 6 to lift, i.e. the side of the placement platform 2 provided with the mounting block is raised, i.e. the placement platform 2 rotates around the first side rod 12, so as to set the inclination angle of the test platform.

[0031] Since the driving rotation angle of the first lifting structure 3 is limited, in the embodiment, the maximum rotation angle of the placement platform 2 driven by the first lifting structure 3 is 60 degrees. Therefore, the second lifting structure 4 is arranged on the basis of the first lifting structure 3.

[0032] Specifically, the second hydraulic cylinder 7 is rotatably connected to the inner side of the first side rod 12 at the bottom of the mounting base 1, and a mounting block is arranged on the inner side of the first side rod 12. The second hydraulic rod rotates on the mounting block, and the other side of the second hydraulic cylinder 7 is rotatably connected to the connection between the second connecting rods 8. The connecting piece 9 is arranged between the first lifting structure 3 and the second lifting structure 4, so as to better adjust the two.

[0033] The connecting piece 9 comprises a cross rod 10 and a connecting rod 11. The connecting rod 11 is vertically connected to the end of the cross rod 10. In fact, the upper first connecting rod 6 is rotatably connected to the upper side of the connecting rod 11. The lower second connecting rod 8 is rotatably connected to the lower side of the connecting rod 11. The upper second connecting rod 8 is rotatably connected to the mounting portion at the bottom of the placement platform 2. Therefore, after the second hydraulic cylinder 7 is started, the included angle between the second connecting rods 8 becomes larger, and the upper second connecting rod 8 opens the placement platform 2 along the first side rod 12. In the embodiment, the maximum angle can be opened to 120 degrees. The combination of the two can achieve a larger angle of use.

[0034] The connecting rod 11 and the cross rod 10 are connected by a reinforcing rod 15. The connecting piece 9 is integrally formed, has better strength to support the placement platform 2, and is arranged parallel to the ground when the placement platform 2 is parallel to the ground. When the first hydraulic cylinder 5 is started, the connecting rod will not affect the placement platform 2. In the embodiment, the actual number of connecting pieces 9 is two groups, corresponding to the first lifting structure 3 and the second lifting structure 4. The first lifting structure 3 and the second lifting structure 4 are also provided with two groups, and the first lifting structure 3 and the second lifting structure 4 are centrally symmetrically distributed with respect to the connecting piece 9, so that the placement platform 2 rotates more stably.

[0035] The test platform further comprises an inclination sensor 16 and a digital inclinometer 17. The inclination sensor 16 is located at the bottom of the placement platform 2. When the placement platform 2 rotates, the real-time angle is displayed on the digital inclinometer 17. A camera is arranged on one side of the device, which can monitor the state of the placement platform 2 in real time.

[0036] The above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the present application; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features therein can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
