[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-5As shown, the hydraulically driven vehicle roll stability testing platform provided in this embodiment of the present invention includes a base 1, a slot 2 on the upper side of the base 1, a testing platform 3 corresponding to the slot 2 rotatably fitted on the upper side of the base 1, a sliding groove 4 at one end of the base 1, a gear 5 at one end of the testing platform 3, a toothed plate 6 that meshes with the gear 5 slidably fitted in the sliding groove 4, and two buffer assemblies installed between the slot 2 and the testing platform 3. The buffer assembly includes a support plate 7 installed at the bottom of the slot 2, multiple first springs 8 and multiple telescopic rods 9 installed on the upper side of the support plate 7, and a buffer plate 10 rotatably fitted on the upper end of the multiple telescopic rods 9 and corresponding to the testing platform 3. One end of the multiple first springs 8 is fixed to the lower side of the buffer plate 10, and a limiting assembly is installed on the upper side of the testing platform 3.

[0027] In this embodiment, foundation 1;

[0028] Specifically, a rod 14 is rotatably fitted on the upper side of the foundation 1. The rod 14 is located in the middle of the test platform 3 and fixed thereto. A gear 5 is located at one end of the rod 14 and is rotatably fitted in the slide groove 4. Through the gear 5, the rod 14 can be driven to rotate, thereby driving the test platform 3 to rotate synchronously, in preparation for the next step of conducting a roll test on the car.

[0029] In this embodiment, a slot 2 is provided on the upper side of the foundation 1, and a test platform 3 corresponding to the slot 2 is rotatably fitted on the upper side of the foundation 1.

[0030] Specifically, a shock-absorbing airbag 15 is installed between the slot 2 and the test platform 3. The shock-absorbing airbag 15 is located between two adjacent buffer plates 10. The shock-absorbing airbag 15 can absorb and dissipate the impact force generated by the car on the test platform 3, thereby achieving the shock absorption effect and further strengthening the protection of the test platform 3.

[0031] Specifically, a motor 24 is installed on one side of the test platform 3. The output end of the motor 24 is fixed to one end of the bidirectional screw 19, and the motor 24 is located in the groove 23. The groove 23 can reduce the occurrence of collision between the motor 24 and the foundation 1 when the test platform 3 rotates.

[0032] In this embodiment, a groove 4 is provided at one end of the foundation 1, and a gear 5 is installed at one end of the test platform 3. A toothed plate 6 that meshes with the gear 5 is slidably fitted in the groove 4.

[0033] Specifically, a plate 11 is installed at one end of the foundation 1, an L-shaped plate 12 is installed at one end of the toothed plate 6, and a hydraulic cylinder 13 is installed on one side of the plate 11. The output end of the hydraulic cylinder 13 is fixed to the upper end of the L-shaped plate 12, and the L-shaped plate 12 is slidably fitted in the slide groove 4. Through the hydraulic cylinder 13, the L-shaped plate 12 can be driven to move horizontally, so that the toothed plate 6 meshes with the gear 5 and rotates, thereby realizing the rotation of the test platform 3.

[0034] In this embodiment, two buffer components are installed between the slot 2 and the test platform 3. The buffer components include a support plate 7 installed at the bottom of the slot 2, a plurality of first springs 8 installed on the upper side of the support plate 7, and a plurality of telescopic rods 9.

[0035] Specifically, the telescopic rod 9 includes a cylinder 16 mounted on the upper side of the support plate 7, a column 17 slidably fitted in the middle of the upper end of the cylinder 16, and a second spring 18 installed between the column 17 and the cylinder 16. The upper end of the column 17 is rotatably fitted with the lower side of the buffer plate 10. Through the second spring 18, the impact force generated by the car on the test platform 3 can be buffered again, further improving the shock absorption effect on the test platform 3.

[0036] In this embodiment, a buffer plate 10 is rotatably fitted to the upper end of multiple telescopic rods 9 and corresponding to the test platform 3. One end of multiple first springs 8 is fixed to the lower side of the buffer plate 10, and a limiting component is installed on the upper side of the test platform 3.

[0037] Specifically, the limiting component includes a bidirectional screw 19 rotatably fitted to one end of the test platform 3, a support rod 20 installed at the other end of the test platform 3, two limiting plates 21 threadedly fitted to both ends of the bidirectional screw 19, and a buffer pad 22 elastically fitted to one side of the limiting plate 21. The two buffer pads 22 correspond to each other. Through the bidirectional screw 19, the bidirectional screw 19 is threadedly fitted to the two limiting plates 21, so that the two limiting plates 21 can move relative to each other, thereby achieving limiting protection for cars of different sizes.

[0038] Specifically, two limiting plates 21 are slidably fitted on the upper side of the test platform 3, and the other ends of the two limiting plates 21 are slidably fitted on the periphery of the support rod 20. A groove 23 connected to the slot 2 is provided on one side of the foundation 1.

[0039] Working steps: 1. When it is necessary to limit and fix the car, first move the car to the upper side of the test platform 3, and then start the motor 24. The output end of the motor 24 drives the bidirectional screw 19 to rotate, so that the bidirectional screw 19 is threadedly engaged with the two limit plates 21, thereby bringing the two buffer pads 22 closer to each other, realizing the limit and fixation of cars of different sizes. At this time, the two limit plates 21 are slidably engaged on the upper side of the test platform 3, and the other end of the two limit plates 21 is slidably engaged on the periphery of the support rod 20.

[0040] 2. When a roll test is required, first activate the limiting component to limit and fix the car, then activate the hydraulic cylinder 13. The output end of the hydraulic cylinder 13 drives the L-shaped plate 12 to move laterally in the slide groove 4, so that the toothed plate 6 meshes with the gear 5 and rotates. The gear 5 drives the rod 14 to rotate, which in turn drives the test platform 3 to rotate synchronously. Thus, the test platform 3 drives the car after it is limited and fixed to rotate synchronously. This can change the tilt angle between the test platform 3 and the foundation 1, thereby realizing the roll test of the car.

[0041] Third, when the test platform 3 needs to be buffered and damped, when the test platform 3 is tilted, the car will press down on one end of the test platform 3, causing one end of the test platform 3 to press down on a buffer plate 10. As a result, multiple first springs 8 absorb the downward impact force on one end of the test platform 3 and dampen it. Then, one end of the test platform 3 drives multiple columns 17 to slide and engage with the upper middle part of multiple cylinders 16. At this time, multiple second springs 18 simultaneously elastically extend and retract, damping it again. At the same time, the upper ends of multiple columns 17 rotate and engage with the lower side of one end of the test platform 3. Then, the other end of the test platform 3 is lifted up, causing multiple first springs 8 and multiple telescopic rods 9 to drive another buffer plate 10 to lift up and fit against the lower side of the other end of the test platform 3. As a result, the upper ends of multiple telescopic rods 9 rotate and engage with the lower side of the other end of the test platform 3. At the same time, the shock-absorbing airbag 15 evenly distributes the impact force to the bottom of the foundation 1, thereby realizing the buffering and damping work of the test platform 3.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
