Technical Field
[0001] The utility model relates to the technical field of automobile bumper experimental detection, in particular to a drop hammer impact experimental device for automobile bumpers. Background Technique
[0002] At present, bumpers are installed at both ends of the front and rear of automobiles, which are mainly used to absorb and buffer external impact forces to protect the vehicle body and the safety of passengers in the vehicle. Since the bumper is very important, it is necessary to optimize the device for bumper impact experiments.
[0003] For example, a performance tester for automobile bumpers is disclosed in the Chinese utility model patent with the publication number CN220525273U. In the above prior art, although it can test whether the impact resistance of the bumper meets the standard within a temperature range, the safety of current automobiles is extremely important, and there are various impact tests for bumpers. However, most of the drop hammers of drop hammer impact devices are relatively single and cannot simulate various sudden impact situations, such as the impact of sharp objects. For such simulation experiments, it is necessary to replace the drop hammer or the drop hammer impact device, which is very troublesome because it requires re-adjusting the data. Therefore, it is necessary to design a drop hammer impact experimental device that can quickly replace the drop hammer according to needs. Summary of the Utility Model

The disassembly component includes a mounting plate arranged on one side of the falling plate and provided with a sliding groove, two sliding blocks slidably installed inside the sliding groove, and a bidirectional threaded rod arranged inside the sliding groove. Both of the two sliding blocks are in threaded cooperation with the bidirectional threaded rod.
[0006] Through the above technical solutions, when different impact experiments need to be carried out, the disassembly component can be used to quickly disassemble the falling hammer, and then the fixing component can be used to quickly fix the replaced falling hammer.
[0007] As a further improvement of the above solution, both ends of the bidirectional threaded rod penetrate through the mounting plate and extend to the outside thereof, and a rotating block is fixedly installed.
[0008] Through the above technical solution, when the rotating block rotates, the bidirectional threaded rod will rotate, thereby causing the two sliding blocks to move together.
[0009] As a further improvement of the above solution, a fixing groove for quick fixed installation is provided on the falling hammer.
[0010] Through the above technical solution, the falling hammer can be quickly and fixedly installed in cooperation with the fixing plate.
[0011] As a further improvement of the above solution, the fixing component includes connecting columns fixedly installed on one side of each sliding block and fixing plates rotatably sleeved on each connecting column. A rubber disk with one side fitting with the adjacent fixing plate is fixedly sleeved on each connecting column.
[0012] Through the above technical solution, when the sliding block drives the fixing plate to move, the falling hammer can be clamped and fixed.
[0013] As a further improvement of the above solution, a plurality of installation grooves adapted to the fixing grooves of falling hammers of different models are provided on both fixing plates.
[0014] Through the above technical solution, falling hammers of different sizes and models can all be clamped and fixed by the fixing plate.

[0017] Compared with the prior art, the beneficial effect of the present utility model lies in:
[0018] By providing a disassembly component and a fixing component, when conducting falling hammer impact experiments on the bumper to different degrees, the disassembly component can be used to quickly disassemble the currently fixed falling hammer, place the falling hammer to be replaced on the fixing component, and then cooperate with the disassembly component to quickly fix the replaced falling hammer.

[0024] Next, in combination with the accompanying drawings and specific implementation manners, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.
[0025] Please refer to Figures 1 - 3 In this embodiment, an automobile bumper drop hammer impact test device includes a drop hammer impact machine 1. A falling plate 2 for performing a drop hammer impact test is provided on the drop hammer impact machine 1. A falling hammer 3 is provided on one side of the falling plate 2. A disassembly component capable of quickly disassembling and replacing the falling hammer 3 is provided on one side of the falling plate 2. A fixing component capable of quickly fixing different falling hammers 3 is provided on one side of the disassembly component. The disassembly component includes a mounting plate 401 provided on one side of the falling plate 2 and having a sliding groove, two sliding blocks 402 slidably mounted inside the sliding groove, and a bidirectional threaded rod 403 provided inside the sliding groove. Both sliding blocks 402 are in threaded cooperation with the bidirectional threaded rod 403. Both ends of the bidirectional threaded rod 403 penetrate through the mounting plate 401 and extend to the outside thereof and are fixedly provided with rotating blocks. When different impact tests need to be performed, the falling hammer 3 can be quickly disassembled using the disassembly component, and then the replaced falling hammer 3 can be quickly fixed using the fixing component.
[0026] Referring to Figure 2 and Figure 3 A fixing groove for quick fixed installation is provided on the falling hammer 3. The fixing component includes a connecting column 501 fixedly mounted on one side of each sliding block 402 and a fixed disk 502 rotatably sleeved on each connecting column 501. A rubber disk 7 with one side fitting with the adjacent fixed disk 502 is fixedly sleeved on each connecting column 501. The rubber disk 7 prevents the fixed disk 502 from rotating by itself. A plurality of mounting grooves adapted to the fixing grooves of different models of falling hammers 3 are provided on both fixed disks 502. The falling hammer 3 can be quickly fixed and installed in cooperation with the fixed disk 502, and falling hammers 3 of different sizes and models can be clamped and fixed by the fixed disk 502.
[0027] Referring to Figures 1 - 3, first moving grooves are formed on both sides of the falling plate 2, second moving grooves are formed on both sides of the mounting plate 401, limiting plates 6 are arranged on both sides of the falling plate 2, and both limiting plates 6 are slidably matched with the adjacent first moving grooves and the adjacent second moving grooves. The limiting plates 6 can be removed to replace the disassembly assembly and the fixing assembly.
[0028] In the embodiment of the present application, the implementation principle of an automobile bumper drop hammer impact test device is as follows: Place the drop hammer 3 to be tested between the two sliding blocks 402, then rotate the fixed disk 502 according to the shape of the fixing groove for installing the drop hammer 3, and then rotate the rotating block, so that the bidirectional threaded rod 403 will rotate, driving the two sliding blocks 402 to move towards the middle together. Finally, the installation groove on the fixed disk 502 will be matched with the fixing groove on the drop hammer 3, and the drop hammer 3 can be clamped and fixed. When the fixed disk 502 on the entire device is not matched with the drop hammer 3, the limiting plate 6 can also be removed, so that the entire mounting plate 401 can be replaced, and then a suitable fixed disk 502 can be replaced. Such a setting can not only quickly replace the drop hammer 3, but also conduct drop hammer impact tests on the bumper to different degrees.
[0029] The above-mentioned implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the protection scope required by the present invention.
