A test bench structure is installed on the top of the chassis. The test bench structure includes four moving components, two bench frames, a connecting plate, four rectangular openings, four fixing seats and four adjusting components. The utility model relates to the technical field of automobile testing. During operation, it can move to a specified position by using four moving components, then contract the four moving components and fix the chassis. Then move the automobile to be tested to the top of the two bench frames, and move the automobile tires to the top of the four adjusting seats. Finally, control the operation of the four adjusting components respectively to adjust the angle of the automobile, so as to achieve the effect of slope adjustment, and has the characteristics of easy operation, simple structure and flexible use.

[0004] In the above-mentioned existing patent literature, when the chassis reaches a specified position through universal wheels, the lifting cylinder is controlled to operate, so that the universal wheels retract into the through holes, so that the bottom of the chassis contacts the ground. At this time, the chassis will collide with the ground surface, and the impact force will cause damage to the chassis and reduce its service life. Therefore, it is necessary to propose a variable slope test bench with auxiliary support to avoid the collision between the chassis and the ground. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a variable slope test bench for automobile testing to solve the problem that in the above-mentioned existing patent literature, when the chassis reaches a specified position through universal wheels, the lifting cylinder is controlled to operate, so that the universal wheels retract into the through holes, so that the bottom of the chassis contacts the ground. At this time, the chassis will collide with the ground surface, and the impact force will cause damage to the chassis and reduce its service life.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0034] Please refer to Figures 1-4As shown in the figure, this embodiment is a variable slope test bench for automobile testing, including:

[0035] A test component, which includes a chassis 11;

[0036] The chassis 11 is used to support other components such as the upper bench 12;

[0037] An auxiliary support component, which includes a support plate 21, two groups of springs 22, a group of grooves 23, and two groups of support blocks 25;

[0038] The support plate 21 is located below the chassis 11. The springs 22 are fixed between the chassis 11 and the support plate 21. The grooves 23 are respectively opened at the corners of the surface of the support plate 21. The support blocks 25 are respectively fixed at the bottom ends of the chassis 11 and the support plate 21;

[0039] The support plate 21 is used for the connection between the support block 25 and the spring 22. The spring 22 is used for the connection between the chassis 11 and the support plate 21. There are two springs 22 in each group. The groove 23 is used for the placement and movement of the universal wheel 15. There are four grooves 23 in total. The support block 25 is used to support the chassis 11 and the support plate 21;

[0040] The test component further includes a bench 12, a cylinder 13, a lifting plate 14, and a universal wheel 15;

[0041] The bench 12 is fixed on both sides of the top end of the chassis 11. The cylinder 13 is located below the bench 12. The lifting plate 14 is fixed to the output end of the cylinder 13. The universal wheel 15 is located at the bottom end of the chassis 11;

[0042] The bench 12 is used to place the automobile. The cylinder 13 is used to drive the lifting plate 14. The lifting plate 14 is used to place the tire. The universal wheel 15 is used for the movement of the device;

[0043] A group of vertical rods 24 are fixedly connected to both sides of the support plate 21. Connecting rings 27 are slidably connected to the surfaces of the vertical rods 24. The universal wheel 15 penetrates through the inside of the groove 23;

[0044] The inner end of the connecting ring 27 is fixedly connected to a short rod 26. The other end of the short rod 26 is fixedly connected to both ends of the chassis 11;

[0045] The vertical rod 24 is used for the connection and movement of the connecting ring 27. The connecting ring 27 and the short rod 26 are both used for the connection between the vertical rod 24 and the chassis 11. The groove 23 is used for the movement of the universal wheel 15. When the chassis 11 moves downward through the spring 22, the connecting ring 27 moves downward on the surface of the vertical rod 24;

[0046] Working principle:

[0047] When in use, when the chassis 11 moves through the universal wheels 15, the universal wheels 15 move within the groove 23. When the chassis 11 moves to the designated position, the lifting cylinder drives the universal wheels 15 to retract into the interior of the chassis 11, and the gravity of the chassis 11 causes the support block 25 to contact the ground, prompting the support block 25 and the support plate 21 to protect and support the upper chassis 11;

[0048] When the vehicle moves onto the bench 12, the gravity of the vehicle causes the spring 22 to contract, causing the chassis 11 to move downward through the spring 22. At this time, the support block 25 at the bottom end of the chassis 11 abuts against the support plate 21, thereby protecting the contracted spring 22. At the same time, the support block 25 at the bottom end of the support plate 21 and the support block 25 at the bottom end of the chassis 11 together support the vehicle;

[0049] Through the interaction between the support plate 21, the spring 22, the groove 23 and the support block 25 in the above steps, the chassis 11 is protected.

[0050] Please refer to Figure 1 、 Figures 5-6 As shown in, on the basis of the above Embodiment 1, this embodiment further includes:

[0051] A guiding and limiting component;

[0052] The guiding and limiting component includes a magnetic attraction area 31, a vertical rod 32, and a guiding plate 33;

[0053] The magnetic attraction area 31 is opened at the center of the top end of the chassis 11. The vertical rod 32 is fixed to one side of the top end of the chassis 11 and is located at one end inside the bench 12. The guiding plate 33 is clamped between the top ends of the vertical rods 32;

[0054] The magnetic attraction area 31 is used for the connection of the guiding plate 33. The vertical rod 32 is used for the clamping of the guiding plate 33. The guiding plate 33 limits the vehicle on the bench 12;

[0055] The guiding plate 33 is provided with a docking groove 34 at the clamping position with the vertical rod 32. The guiding plate 33 is adsorbed above the magnetic attraction area 31;

[0056] The docking groove 34 is used for the insertion of the guiding plate 33. When the guiding plate 33 is inserted into the docking groove 34, the guiding plate 33 is connected to the vertical rod 32. When the guiding plate 33 is not in use, the guiding plate 33 can be magnetically adsorbed above the magnetic attraction area 31;

[0057] Working principle:

[0058] When in use, the guide plate 33 is taken out by hand, and the guide plate 33 is pulled out to separate the guide plate 33 from the magnetic attraction area 31, and then the guide plate 33 is inserted into the docking groove 34 to connect the guide plate 33 with the vertical rod 32. When the car moves onto the platform 12, the front end of the car contacts the guide plate 33, so that the guide plate 33 limits the position of the car on the platform 12 to prevent the car from slipping.

[0059] When the guide plate 33 is not in use, the guide plate 33 is pulled out by hand to separate the guide plate 33 from the docking groove 34, and the guide plate 33 is magnetically attracted above the magnetic attraction area 31;
