[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] Please see Figures 1-5 A sound barrier impact energy absorption structure includes a base 1, a sound barrier body 2 installed on top of the base 1, and mounting plates 3 fixed at both the front and rear ends of the bottom of the base 1. The mounting plates 3 have through-shaped slots 12 for easy subsequent installation. The front end of the base 1 is provided with a support plate 4, an elastic folding square tube 5, and a damping plate 6. The support plate 4 is installed on the front end surface of the base 1, and the elastic folding square tube 5 is installed between the support plate 4 and the damping plate 6 and can contract to absorb energy after being compressed, so that the damping plate 6 and the support plate 4 can move close to each other.

[0029] A damping buffer component is provided between the damping plate 6 and the support plate 4. The number of damping buffer components is not less than two and they are equally distributed between the damping plate 6 and the support plate 4, thereby further improving the energy absorption limit of the overall device after being subjected to an impact. The component includes a damping rod 7 and a first spring 8. One end of the damping rod 7 is fixed to the rear end surface of the damping plate 6, and there is a buffer space between the other end of the damping rod 7 and the support plate 4. The first spring 8 is fitted on the outside of the damping rod 7, and both ends of the first spring 8 are fixed to the surface of the damping plate 6 and the surface of the support plate 4, respectively. Limiting rings 10 are fixed on both sides of the damping plate 6, and an elastic connector 11 is installed between two adjacent limiting rings 10.

[0030] The number of limit rings 10 is not less than two and they are equidistantly distributed along the longitudinal direction of the damping plate 6 structure to ensure the linkage effect after being connected with the same number of elastic connectors 11.

[0031] The elastic connector 11 includes a second spring 111, with hooks 112 fixed at both ends of the second spring 111. The hooks 112 can be fitted with the limiting ring 10 for limiting. The surfaces of the second spring 111 and the hooks 112 are coated with an anti-corrosion coating to improve the service life of the structure.

[0032] When in use, after the whole device is impacted, the elastic folding square tube 5 and the first spring 8 will be compressed and contracted synchronously, which will cause the combined top support plate 4 formed by the damping plate 6 and the damping rod 7 to perform multiple damping buffering, fully ensuring the impact energy absorption effect.

[0033] During the displacement buffering process of the impacted damping plate 6 and related structures, the adjacent damping plates 6 on both sides and their corresponding related structures will undergo synchronous deformation damping buffering under the action of the linkage structure formed by the limiting ring 10 and the elastic connector 11, thereby forming a large-area energy absorption buffering effect with the main energy absorption in the impact area and the linkage energy absorption in the surrounding area.

[0034] Please see Figure 1 The front end of the base 1 has a screw hole, and the corner of the support plate 4 has a countersunk hole aligned with the screw hole. The support plate 4 and the base 1 can be detached and installed by screws and countersunk holes being fitted together and then spirally engaged with the screw hole.

[0035] When in use, if the support plate 4 and the structure associated with the support plate 4 are damaged, the screws between the support plate 4 and the base 1 can be directly removed, and the elastic connecting parts 11 on both sides of the damping plate 6 can be separated. After that, the support plate 4 and the structure associated with the support plate 4 can be replaced and repaired in a modular manner.

[0036] Please see Figures 6-7Both sides of the bottom of the elastic folding square tube 5 are provided with clearance holes 13. When the elastic folding square tube 5 is compressed, the air in the combined space formed by the elastic folding square tube 5, the support plate 4, and the damping plate 6 is buffered and flows through the clearance holes 13. An auxiliary energy-absorbing component 9 is provided between the damping plate 6 and the support plate 4. The auxiliary energy-absorbing component 9 includes a rubber bag 91, which contains powder pigment. A connecting tube 92 is fixedly nested at the bottom of the rubber bag 91, and a sealing plug 93 is snapped into the connecting tube 92. An annular groove is provided on the inner wall of the connecting tube 92, and a sealing ring 94 is fixedly sleeved on the surface of the sealing plug 93 and nested in the annular groove.

[0037] During use, when the support plate 4 and the structure associated with the support plate 4 are subjected to energy absorption by the device, the air in the combined space formed by the elastic folding square tube 5, the support plate 4, and the damping plate 6 flows out quickly through the clearance hole 13, assisting the elastic folding square tube 5 in the deformation process and fully optimizing the buffering effect. Similarly, the rubber bag 91 inside the auxiliary energy-absorbing component 9 will also be compressed and deformed synchronously for buffering. At the same time, the powder pigment stored in the rubber bag 91 breaks through the sealing plug 93 and expands into the environment where the impact occurs along with the air flowing out of the combined space. In this way, while further improving the buffering effect, it can also mark the impact area and vehicle, which can provide a conspicuous location mark for the current traffic drone patrol, and can also provide a conspicuous reminder for other vehicles on the road to detour in time.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
