[0022] Example 1

[0023] like Figures 1 to 7 As shown, the system includes a base plate 1, a triangular plate 11 fixed to one side of the base plate 1, and two sets of support plates 12 fixed to one side of the base plate 1. Each support plate 12 has a support shaft 13 rotatably connected to its top. Each support shaft 13 has a first support block 14 fixed to both ends. Each first support block 14 has a top plate 15 fixed to its top. An adjustment component is provided on one side of the bottom of the top plate 15, and a fixing component is provided on the top of the top plate 15. The adjustment component facilitates the laboratory's testing of vehicles, and the fixing component can fix the vehicle to be tested, thereby improving the stability of the vehicle body.

[0024] The adjustment assembly includes a second support block 16, which is fixed to one side of the bottom of the top plate 15. A connecting shaft 17 is fixed to one side of the second support block 16 that is close to each other. Two sets of baffles 18 are fixed to the middle of the bottom plate 1. A first lead screw 19 is rotatably connected to one side of the baffles 18 that is close to each other, and a second lead screw 111 is rotatably connected to one side of the baffles 18 that is close to each other. A gear 112 is fixed to one end of both the first lead screw 19 and the second lead screw 111. A servo motor 113 is installed and connected to one end of the first lead screw 19. A threaded connection is made to the middle of both the first lead screw 19 and the second lead screw 111. The movable block 114 has bearings 115 fixedly attached to its top. Support rods 116 are rotatably connected to both ends of the bearings 115. The top of the support rods 116 is rotatably connected to the middle of the connecting shaft 17. Two sets of synchronous shafts 117 are fixedly attached to the side of the support rods 116 that are close to each other. By adjusting the configuration of the components, the angle of the top plate 15 can be easily adjusted, thereby changing the angle of the vehicle at the top plate 15. This improves the flexibility of vehicle deployment when the vehicle is tested in the laboratory, thus facilitating the completion of the testing work and reducing the complexity of the work.

[0025] The fixing assembly includes a first fixing plate 2, which is fixed to one side of the top plate 15. Two sets of second fixing plates 21 are fixed to the other side of the top plate 15. A shaft 22 is slidably connected between the middle of the first fixing plate 2 and the second fixing plate 21. Sliding columns 23 are slidably connected to both sides of the second fixing plate 21. A first limiting pad 24 is fixed to one end of the sliding column 23, and a wedge block 25 is fixed to the other end of the sliding column 23. A compression spring 26 is connected to one side of the first limiting pad 24, and the other end of the compression spring 26 is connected to the side of the second fixing plate 21. A second limiting pad 27 is fixed to one end of the shaft 22, and a wedge groove 28 is opened at the other end of the shaft 22. An inclined groove 29 is opened at the end of the shaft 22. The fixing assembly can fix the vehicle, thereby reducing the possibility of the vehicle shifting position during inspection, which could affect the normal operation of the inspection work and cause safety accidents.

[0026] Example 2

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, each movable block 114 has a guide post 3 fixedly connected to its bottom. A U-shaped plate 31 is fixedly connected to the bottom of the guide post 3. A rotating shaft 32 is rotatably connected to the middle of the U-shaped plate 31. A roller 33 is fixedly connected to the middle of the rotating shaft 32. The bottom of the roller 33 contacts the surface of the base plate 1. Through the cooperation between the guide post 3 and the roller 33, the movable block 114 can be supported. This reduces the excessive pressure on the first lead screw 19 and the second lead screw 111 caused by the large weight at the top plate 15, which could lead to deformation and accelerated wear of the first lead screw 19 and the second lead screw 111 due to the heavy load.

[0028] Each roller 33 has a limiting groove 4 in the middle. Two sets of guide rails 41 are fixed in the middle of the base plate 1. The limiting groove 4 and the guide rail 41 fit together. With the cooperation of the limiting groove 4 and the guide rail 41, the movement trajectory of the moving block 114 can be restricted, thereby improving the stability of the moving block 114 when it moves and thus enhancing the reliability of the adjustment work.

[0029] Example 3

[0030] like Figure 1 As shown, the side of the triangle 11 closest to the base plate 1 is arc-shaped, which reduces the friction between the top plate 15 and the triangle 11, thereby assisting in the smoothness of the adjustment work and improving the smoothness and stability of the adjustment work.

[0031] The usage process of the adjustable-angle laboratory vehicle fixing device provided by this utility model is as follows: The adjustable components facilitate vehicle testing in the laboratory, while the fixing components secure the vehicle, thereby improving its stability. When the laboratory needs to test the vehicle, it can first be moved to the top plate 15 via the triangular plate 11. Then, the servo motor 113 is driven to rotate the first lead screw 19 at the baffle 18. Simultaneously, the gear 112 at the first lead screw 19 rotates accordingly. Since the gears 112 at the first lead screw 19 and the second lead screw 111 are meshed, the rotation of the gear 112 at the first lead screw 19 will drive the gear 112 at the second lead screw 111 to rotate, thus driving the second lead screw... Rotation of screw 111 causes the first lead screw 19 and the second lead screw 111 to move the moving block 114 synchronously. At this time, the bearing 115 connects the two sets of moving blocks 114, and the support rod 116 and connecting shaft 17 restrict the movement trajectory of the moving block 114, allowing it to move linearly. Simultaneously, the movement of the moving block 114 causes the bearing 115 to move, which in turn pulls the support rod 116, causing its two ends to rotate at the connecting shaft 17 and the bearing 115 respectively. This rotation of the support rod 116 causes the synchronous shaft 117 to move, changing the positions of its two ends and thus altering its tilt angle. This change in the tilt angle of the support rod 116 pulls the connecting shaft 17 and the top plate 114. The position of 5 changes, thereby causing a change in the angle of one side of the top plate 15, thus adjusting the angle of the top plate 15. When the angle of the top plate 15 is adjusted to a suitable position, the operation of the servo motor 113 can be stopped. This step, through the setting of the adjustment component, facilitates the adjustment of the angle of the top plate 15, thereby changing the angle of the vehicle at the top plate 15. This improves the flexibility of vehicle deployment when the vehicle is tested in the laboratory, thus facilitating the completion of the testing work and reducing the complexity of the work. After the vehicle is moved to the top plate 15, its wheel hub is first positioned on the side where the first fixing plate 2 and the second fixing plate 21 are close to each other. Then, one end of the insertion shaft 22 is inserted into the first fixing plate 2, and the insertion shaft 22 is inserted into the second fixing plate through the hollow part of the vehicle wheel hub. When the end of the insert shaft 22 is inserted into the middle of the second fixing plate 21, the inclined groove 29 will contact the wedge block 25 and generate a squeezing force. At this time, the wedge block 25, under the influence of the squeezing, will drive the sliding column 23 and the first limiting pad 24 to move outward of the second fixing plate 21, and the compression spring 26 will be compressed. When the insert shaft 22 continues to be inserted, the wedge groove 28 will move to the wedge block 25. At this time, the wedge block 25 will be less restrained by the squeezing force, and the compression spring 26 will rebound, simultaneously driving the wedge block 25 and the sliding column 23 to move towards the wedge groove 28 until the wedge block 25 is stuck in the wedge groove 28. This serves to fix the insert shaft 22 and, together with the insert shaft 22, fix the vehicle. This step can fix the vehicle through the fixing assembly.This reduces the likelihood of vehicle misalignment during inspection, which could affect the normal operation of the inspection and cause safety accidents. When the moving block 114 moves, it drives the guide post 3, U-shaped plate 31, rotating shaft 32, and roller 33 to move synchronously. Because the roller 33 contacts the surface of the base plate 1, friction occurs during its movement. This friction causes the roller 33 to drive the rotating shaft 32 to rotate. This step, through the cooperation between the guide post 3 and the roller 33, supports the moving block 114, thus reducing the excessive pressure on the first lead screw 19 and the second lead screw 111 caused by the heavy weight of the top plate 15. This prevents the first and second lead screws from deforming under the load, which could exacerbate the problem. When wear occurs, the roller 33 rotates, causing the limiting groove 4 to rotate synchronously. During this rotation, the limiting groove 4 is restricted by the guide rail 41 and moves along its surface. This interaction between the limiting groove 4 and the guide rail 41 helps to limit the movement trajectory of the moving block 114, thereby improving its stability and enhancing the reliability of the adjustment process. When the adjustment assembly is in operation, the side of the top plate 15 closest to the triangular plate 11 moves up and down. The curved design of the side of the triangular plate 11 reduces friction between the top plate 15 and the triangular plate 11. This reduction in friction facilitates smooth adjustment, improving its smoothness and stability.

[0032] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
