It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but do not constitute a limitation to the present invention.

[0028] Embodiment:

[0029] As Figures 1-4 shown, a guardrail includes a base 100, an elastic support 200, and a guardrail body 300;

[0030] The base 100 has a basic shape and thickness;

[0031] The elastic support 200 includes a first support part 210 and a second support part 220. There are two first support parts 210 which are relatively fixed on the top surface of the base 100. The two ends of the guardrail body 300 are respectively arranged on the adjacent first support parts 210. The second support part 220 is inclined and connects the guardrail body 300 and the base 100; and both the first support part 210 and the second support part 220 have elasticity, so that the guardrail body 300 can maintain its position and reset after moving;

[0032] The two ends of the guardrail body 300 are respectively provided with outward-extending insertion parts 400, and the insertion parts 400 can be inserted into the first support part 210.

[0033] The protective fence realizes elastic buffering through the arrangement of the elastic support member 200, plays a buffering role on the impact of the vehicle and consumes part of the impact energy, reduces the harm caused by the vehicle impact, and protects the occupants in the vehicle. At the same time, the second support portion 220 is inclined and configured as a diagonal brace, thereby improving the structural strength of the protective fence and enhancing the impact resistance ability of the protective fence; both the first support portion 210 and the second support portion 220 have elasticity, which not only plays a buffering role but also enables the protective fence body 300 to have a reset function, reducing the workload of the staff.

[0034] Optionally, the protective fence body 300 can be configured in any suitable shape. Among them, the protective fence body 300 is connected to the first support portion 210 through the insertion portion 400, so that the protective fence body 300 is fixed on the base 100. The protective fence body 300 is also connected to the second support portion 220, and the second support portion 220 is configured as a diagonal brace to improve the structural strength of the protective fence.

[0035] Preferably, a plurality of second support portions 220 can be provided to improve the structural strength of the protective fence as much as possible.

[0036] During operation, a plurality of such protective fences are arranged on both sides of roads, bridges, etc. For small impacts, after the vehicle collides with the protective fence body 300, the impact force is absorbed by the elastic support member 200. After the vehicle moves away, the elastic support member 200 enables the protective fence body 300. For large impacts, the protective fence body 300, and even the protective fence will be deformed, and at this time, the staff needs to replace it in time.

[0037] In this embodiment, the first support portion 210 includes a base plate 211, a first damper 212, and a first spring 213;

[0038] The bottom surface of the base plate 211 is fixedly connected to the top surface of the base 100, and a sliding groove is provided on the top surface of the base plate 211;

[0039] The first damper 212 has opposite ends, one of which is fixedly connected to the end wall of the sliding groove, and the other end is used to connect the insertion portion 400 of the protective fence body 300. The first spring 213 is sleeved on the first damper 212;

[0040] Correspondingly, the insertion portion 400 of the protective fence body 300 is inserted into the sliding groove and connected to the end of the first damper 212.

[0041] Based on the above design, by providing the sliding groove on the base plate 211, it not only provides an installation space for the first damper 212 and the first spring 213 but also guides the moving direction of the first damper 212 and the first spring 213, ensuring that the protective fence body 300 can be correctly reset. Therefore, on the basis of the buffering function, the first support portion 210 also plays a reset role.

[0042] Meanwhile, the guardrail body 300 is inserted into the chute through the insertion part 400 and connected to the first damper 212. Preferably, the insertion part 400 is fixedly connected to the first damper 212 to improve the connection stability. Optionally, the first damper 212 and the first spring 213 can be respectively selected from any suitable commercially available models.

[0043] In this embodiment, there is at least one second support part 220, and when there are multiple second support parts 220, the second support parts 220 are arranged at equal intervals along the length direction of the base 100. Based on the above design, according to the use requirements, the number of the second support parts 220 is appropriately increased or decreased so that the structural strength of the guardrail meets the requirements.

[0044] In this embodiment, the second support part 220 includes a second damper 221 and a second spring 222. The second damper 221 has opposite ends, and the two ends are respectively connected to the guardrail body 300 and the base 100. The second spring 222 is sleeved on the second damper 221; correspondingly, supports 500 for connecting the second damper 221 are respectively provided on the base 100 and the guardrail body 300.

[0045] Based on the above design, compared with the first support part 210, the structure of the second support part 220 is simpler, which helps to reduce the economic cost. At the same time, the second support part 220 not only plays a buffering role but also plays a role in improving the structural strength. When the guardrail body 300 is reset, the elastic force of the second support part 220 can also be used for the reset of the guardrail body 300.

[0046] Optionally, the second damper 221 and the second spring 222 can be respectively selected from any suitable commercially available models, and the support 500 can be constructed into any suitable shape.

[0047] It is easy to understand that the guardrail body 300 can be constructed into any suitable shape, such as selecting any suitable commercially available frame structure. Further, this embodiment provides a structure, specifically:

[0048] In this embodiment, as Figure 1 、 2 and shown in 4, the guardrail body 300 includes a base frame 310 and a guard cylinder 320;

[0049] The base frame 310 includes an upper plate 311, a lower plate 312 and two side plates 313. The upper plate 311 and the lower plate 312 are arranged oppositely and connected by the side plates 313. The lower ends of the side plates 313 extend outside the lower plate 312 to form the insertion part 400;

[0050] A plurality of protective cylinders 320 are provided and rotatably arranged in the base frame 310. Correspondingly, the protective cylinder 320 includes a cylinder body 321 and a rotating shaft 322. The rotating shaft 322 is arranged on the cylinder body 321, and both ends of the rotating shaft 322 penetrate through the cylinder body 321 and are rotatably connected to the upper plate 311 and the lower plate 312 respectively;

[0051] Correspondingly, the first support portion 210 is connected to the base frame 310 through the insertion portion 400, and the connection portion of the second support portion 220 and the base frame 310 is located on the upper plate 311.

[0052] Based on the above design, the rotating protective cylinder 320 is used to replace the existing rod. When the vehicle collides, the protective cylinder 320 will rotate, thereby changing the sliding friction between the guardrail and the vehicle into rolling friction, reducing the frictional damage of the vehicle. At the same time, the vehicle will move along the layout direction of the protective cylinder 320, changing the moving direction of the vehicle to a certain extent and reducing the probability of the vehicle rushing out of the road bridge, etc.

[0053] In a possible implementation, preferably, the protective cylinder 320 includes an airbag 323 located inside the cylinder body 321. Based on the above design, the buffer effect of the protective cylinder 320 is increased through the airbag 323, and the cylinder body 321 is also protected, reducing the probability of damage to the cylinder body 321 during the impact and improving the service life of the protective cylinder 320.

[0054] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
