[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] See Figures 1-5 This utility model provides the following two technical solutions:

[0029] First embodiment: A tilt testing device for automobile inspection, comprising:

[0030] Two first connecting parts 1, each of which has two limiting components 2 slidably mounted on it, and each of the four limiting components 2 includes a limiting seat 21. The limiting seat 21 is mounted on the first connecting part 1, and a first bidirectional lead screw 22 is rotatably mounted inside the limiting seat 21. A first motor 23 is fixedly mounted on one end of the limiting seat 21, and the output end of the first motor 23 is fixedly connected to the first bidirectional lead screw 22. One end of a connecting rod 24 is threaded onto both ends of the first bidirectional lead screw 22, and a clamping plate 25 is fixedly mounted on the other end of each connecting rod 24. The limiting components 2 are used to limit the tires during vehicle inspection.

[0031] Two second connectors 3 are installed at the bottom of the first connector 1, and the second connectors 3 are used to support the first connector 1;

[0032] Angle adjustment component 4 includes four first hydraulic presses 41, which are respectively fixedly installed at both ends of the first connecting member 1 of the two second connecting members 3. A second hydraulic press 42 is fixedly installed at the center of the bottom of the first connecting member 1 of the two second connecting members 3. A third hydraulic press 43 is fixedly installed at the center of the bottom of the two first connecting members 1, which is used to adjust the tilt angle of the first connecting member 1 and the second connecting member 3.

[0033] Mounting blocks 7 are fixedly installed on the bottom of both first connecting parts 1. The output ends of the two third hydraulic presses 43 are fixedly connected to the two mounting blocks 7 respectively. The bottom of the mounting blocks 7 and the bottom of the second connecting parts 3 are on the same horizontal line. The bottoms of the four first hydraulic presses 41, the two second hydraulic presses 42, and the two third hydraulic presses 43 are all on the same horizontal line.

[0034] Two second hydraulic presses 42 and two third hydraulic presses 43 are all installed at the center line of the two adjacent first hydraulic presses 41.

[0035] After the first motor 23 starts, its output end drives the first bidirectional lead screw 22 to rotate. Since the threads at both ends of the first bidirectional lead screw 22 are in opposite directions, when the first bidirectional lead screw 22 rotates, the two connecting rods 24 connected to it will move towards or away from each other along the axial direction of the lead screw within the limiting seat 21. In this way, the clamping plates 25 at the ends of the two connecting rods 24 can clamp or release the car tire, thereby achieving the purpose of limiting the tire during car testing and preventing the tire from shifting during the tilt test and affecting the test results. When it is necessary to adjust the tilt angle, it can be achieved by controlling the extension and retraction of each hydraulic press. For example, by extending the first hydraulic press 41 on one side and shortening the first hydraulic press 41 on the other side, and coordinating with the appropriate extension and retraction adjustment of the second hydraulic press 42 and the third hydraulic press 43, the tilt angle of the first connecting member 1 and the second connecting member 3 can be changed to simulate the state of the car under different tilt road conditions. The tilt test of the car can be performed in all directions (front, back, left, and right) through the angle adjustment component 4. The mounting block 7 ensures the balance and stability of the entire device in the initial state, providing a reliable foundation for subsequent tilt angle adjustment.

[0036] In this embodiment, the movement of the clamping plate 25 is controlled by the first motor 23 driving the first bidirectional lead screw 22, which enables precise positioning of the car tires. This is applicable to tires of different sizes, improving the versatility of the device and the accuracy of the test results. It ensures that the tire position is fixed during the tilt test and that the test data will not be inaccurate due to tire slippage. Through the design of the angle adjustment component 4, the tilt angle can be adjusted in multiple angles and directions to meet the needs of different car tilt tests. It can simulate various complex road conditions and tilt angles, providing a more comprehensive and realistic test environment for car performance testing and helping to more accurately evaluate the car's performance under different tilt conditions.

[0037] The second implementation differs from the first implementation in that: the four limiting components 2 are slidably mounted on the two first connecting members 1 by two lateral adjustment components 5, and the two ends of the two first connecting members 1 are slidably mounted on the second connecting members 3 by two longitudinal adjustment components 6.

[0038] The two lateral adjustment components 5 include two first slide grooves 51, both of which are opened on the two first connecting parts 1. Four limiting components 2 are slidably installed at the four first slide grooves 51 respectively. A second motor 52 is fixedly installed at the bottom of the first connecting part 1. A second lead screw 53 is fixedly installed at the output end of the second motor 52. The second lead screw 53 is rotatably installed at the bottom of the first slide groove 51. The four limiting components 2 are threadedly installed at both ends of the two second lead screws 53 respectively.

[0039] Both longitudinal adjustment components 6 include two second slide grooves 61, both second slide grooves 61 are opened on the top of the second connector 3, one end of each of the two first connectors 1 is slidably installed in the two second slide grooves 61, a third motor 62 is fixedly installed at the end of the second connector 3, a third lead screw 63 is rotatably installed inside the second connector 3, the output end of the third motor 62 passes through the second connector 3 and is fixedly connected to the third lead screw 63, and one end of each of the two first connectors 1 is threadedly installed at both ends of the third lead screw 63.

[0040] The second motor 52 in the two lateral adjustment components 5 is started, and its output drives the second lead screw 53 to rotate. Because the four limiting components 2 are respectively threaded on both ends of the two second lead screws 53, and the limiting components 2 are slidably installed in the first slide groove 51, when the second lead screw 53 rotates, according to the principle of threaded transmission, the limiting components 2 will move laterally in the first slide groove 51 along the axial direction of the lead screw. By controlling the rotation direction and number of rotations of the second motor 52, the lateral position of the limiting components 2 on the first connecting member 1 is precisely adjusted, so that the device can adapt to cars with different wheelbases in the lateral direction; the third motor in the two longitudinal adjustment components 6 is started. When motor 62 starts, its output end passes through the second connecting piece 3 and drives the third lead screw 63 to rotate. Since one end of each of the two first connecting pieces 1 is threaded onto both ends of the third lead screw 63, and one end of each first connecting piece 1 is slidably mounted on the second slide groove 61, when the third lead screw 63 rotates, according to the principle of thread transmission, the two first connecting pieces 1 will move longitudinally along the axial direction of the lead screw within the second slide groove 61. By controlling the rotation direction and number of rotations of the third motor 62, the position of the two first connecting pieces 1 on the second connecting piece 3 can be precisely adjusted, so that the device can be adapted to cars with different wheelbases in the longitudinal direction and meet the tilt test requirements of different car models.

[0041] In this embodiment, by setting the lateral adjustment component 5 and the longitudinal adjustment component 6, the device can be adapted to cars with different wheelbases, making it suitable for the detection of various car models, thus expanding its application range and improving the versatility and practicality of the device.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] In use, based on the wheelbase and track width of the vehicle being tested, the third motor 62 drives the third lead screw 63 to rotate, adjusting the position of the two first connecting parts 1 on the second connecting parts 3. Then, the second motor 52 drives the second lead screw 53 to rotate, adjusting the position of the four limiting components 2 on the first connecting parts 1. The vehicle is then slowly driven into the device, so that the four tires are respectively positioned between the clamping plates 25 of the four limiting components 2. Next, the first motor 23 is started, driving the first bidirectional lead screw 22 to rotate, causing the clamping plates 25 at the ends of the two connecting rods 24 to move towards each other, clamping the vehicle tires. According to the test requirements, the tilt angle and direction to be simulated are determined. The tilt angle is adjusted by controlling the extension and retraction of the four first hydraulic presses 41, the two second hydraulic presses 42, and the two third hydraulic presses 43. For example, to perform a left tilt test, the first hydraulic press 41 on the left side can be shortened, and the first hydraulic press 41 on the right side can be extended. At the same time, the extension and retraction of the second hydraulic presses 42 and the third hydraulic presses 43 are adjusted appropriately to maintain the balance and stability of the device. Tilt tests of different directions and angles are performed in sequence according to the test requirements.
