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.

[0024] Example:

[0025] Please see Figure 1 - Figure 4 This embodiment of a bumper frame collision testing device includes a support plate 1 and a fixed plate fixedly connected to the upper end of the support plate 1. A motor 2 is fixedly connected to one side of the fixed plate, and a rotating disk 3 is fixedly connected to the output end of the motor 2. A rotating shaft 4 is fixedly connected to the end of the rotating disk 3 away from the center. A ring 19 is fixedly connected to one end of the rotating shaft 4. The ring 19 is hollow. A fixed rod 5 is slidably connected to the inner wall of the ring 19. A rotating plate 6 is fixedly connected to both the upper and lower ends of the fixed rod 5. A fixed shaft 7 is provided through the left half of the two rotating plates 6. Limit blocks 9 are fixedly connected to both the upper and lower ends of the fixed shaft 7. The rotating plate 6 and the fixed shaft 7 are slidably connected. The lower end of the fixed shaft 7 is fixedly connected to the upper end of the support plate 1.

[0026] The rotation of the rotating disk 3 by the motor 2 is existing technology, so it is not described in detail in this embodiment.

[0027] The rotating disk 3 is driven to rotate by the rotating motor 2. At the same time, the rotating shaft 4 is fixedly connected to the end of the rotating disk 3 away from the center. The rotating shaft 4 drives the ring 19 to move eccentrically. The ring 19 slides around the fixed rod 5. The rotating plate 6 slides left and right with the ring 19. The sliding component connected to the lower end of the rotating plate 6 can limit the sliding position of the rotating plate 6 to prevent the rotating plate 6 from being displaced during sliding. The swing component connected to one end of the rotating plate 6 swings left and right with the rotation of the rotating plate 6. By fixing the swing component to the fixed component, the bumper 14 will swing left and right with the swing component when it swings. By fixing the swing position of the collision component, the collision component will impact various positions of the bumper 14 when it swings, so as to achieve the effect of testing various positions of the bumper 14.

[0028] Two rotating plates 6 are fixedly connected to a swing plate 8 on the left side, and a fixed frame 11 is fixedly connected to one side of the swing plate 8.

[0029] The front and rear ends of the fixed frame 11 are fixedly connected to the clamping frame 12. The upper ends of the two clamping frames 12 are provided with threaded rods 13. The upper ends of the two threaded rods 13 are fixedly connected to the rotating blocks. The inside of the two clamping frames 12 is movably provided with a safety bar 14. The lower end of the fixed frame 11 is fixedly connected to several limit rods 20.

[0030] The limiting rod 20 has a U-shaped groove 21 slidably provided around its periphery. The lower end of the U-shaped groove 21 is fixedly connected to the upper end of the support plate 1. The limiting rod 20 is slidably connected inside the U-shaped groove 21. Sliding grooves are provided on both sides of the U-shaped groove 21. A slider 24 is fixedly connected to the lower end of the limiting rod 20. The slider 24 is slidably connected inside the sliding groove.

[0031] Two limiting threaded rods 22 are provided through the upper end of the slider 24. The two limiting threaded rods 22 are symmetrically distributed. Arc grooves 23 are opened on the periphery of the two limiting threaded rods 22. The arc grooves 23 are embedded in the support plate 1. The arc grooves 23 are provided with threads, and the limiting threaded rods 22 and the arc grooves 23 are threadedly connected.

[0032] By fixing the swing plate 8 to the left side of the two rotating plates 6, the swing plate 8 will swing along with the movement of the rotating plates 6. The clamping frames 12 at both ends of the fixed frame 11 can fix the position of the bumper 14. By providing threaded rods 13 through the upper ends of the two clamping frames 12, the bumper 14 can be tightened by rotating the threaded rods 13 downwards, preventing the bumper 14 from falling off when it is not securely fixed and when it is hit by the collision component. Several limiting rods 20 are provided at the lower end of the fixed frame 11. The limiting rods 20 are provided with U-shaped grooves 21 on their circumference. The limiting rods 20 can be movably provided with U-shaped grooves 21 in the U-shape. The sliding inside the groove 21 can prevent the swing plate 8 from being damaged when the collision component hits the bumper 14. By opening the sliding grooves on both sides of the U-shaped groove 21, the sliding position of the slider 24 can be limited. When the swing plate 8 drives the bumper 14 to rotate to the accurate angle, the motor 2 stops rotating. By rotating the two limiting threaded rods 22 that are set through the upper end of the slider 24 downward, the two limiting threaded rods 22 will be threadedly connected with the threads inside the arc groove 23, so as to achieve the effect of fixing the position of the fixed frame 11, preventing the fixed frame 11 from moving backward and damaging the swing plate 8 when the bumper 14 is hit by the collision device.

[0033] A collision ball 17 is provided on the left side of the bumper 14 and the collision ball 17 does not contact the bumper 14. A swing rod is fixedly connected to the periphery of the collision ball 17, and a fixing block 16 is fixedly connected to the upper end of the swing rod.

[0034] A rotating rod is installed through the inside of the fixed block 16. Both ends of the rotating rod are fixedly connected to the support plate 15. The diameters of the two ends of the rotating rod are different, with the smaller diameter at the end of the rotating rod that is installed through the inside of the fixed block 16.

[0035] By installing a rotating rod through the inside of the fixed block 16 and fixing the collision ball 17 to the lower end of the fixed block 16 via a swing rod, the height of the collision ball 17 can be adjusted by pulling the swing rod, thereby controlling the impact force of the collision ball 17 on the bumper 14, and thus achieving the test of the maximum bearing capacity of the bumper 14. The swing position of the fixed block 16 can be fixed by setting rotating rods with different diameters at both ends, preventing the fixed block 16 from shifting position during swing.

[0036] The working principle of the above embodiments is as follows:

[0037] In use, by setting the rotating shaft 4 at a position offset from the center of the rotating disk 3, when the motor 2 drives the rotating disk 3 to rotate, the ring 19 will move up and down around the fixed rod 5, and at the same time the rotating plate 6 will rotate around the fixed shaft 7. The swing plate 8 will swing with the rotating plate 6. By fixing the fixed frame 11 to one side of the swing plate 8, the fixed frame 11 will drive the bumper 14 to swing with the swing plate 8. When the swing plate 8 swings to a certain position, the rotating motor 2 is turned off and the swing plate 8 stops swinging. By rotating the limiting threaded rod 22 into the arc groove 23, the position of the fixed frame 11 can be fixed. At this time, by pulling the swing rod, the height of the collision ball 17 can be adjusted, thereby controlling the magnitude of the impact force of the collision ball 17 on the bumper 14, realizing the test of the maximum impact force that the bumper 14 can withstand at different positions.

[0038] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
