[0034] See Figure 1This utility model embodiment provides a simulated guardrail for intelligent driving testing. The simulated guardrail includes a first post 10 and a second post 20 arranged adjacent to each other, a first base 30 and a second base 40 correspondingly connected to the first post 10 and the second post 20, and a flexible crossbeam 50 disposed between the first post 10 and the second post 20. Here, the bottom of the first post 10 is fixed to the first base 30, the bottom of the second post 20 is fixed to the second base 40, and both ends of the flexible crossbeam 50 are respectively fixed to the first post 10 and the second post 20, so that the flexible crossbeam 50 is disposed between the first post 10 and the second post 20 to form a simulated guardrail.
[0035] In one embodiment, the first column 10 and the second column 20 have the same structural configuration. Taking the first column 10 as an example, the configuration structure of the first column 10 and the second column 20 will be specifically described as follows: Figure 2 As shown, the system includes: a first column 10 comprising a first flexible column 110, a second flexible column 120, and at least one rigid support column 130. The first flexible column 110 and the second flexible column 120 are fixed together facing each other. The at least one rigid support column 130 is a long, straight column and is arranged along the height direction of the first flexible column 110 and the second flexible column 120. The at least one rigid support column 130 is enclosed within the internal space formed between the first flexible column 110 and the second flexible column 120. The number of rigid support columns 130 can be set according to actual needs; in this embodiment, it can be specifically set to two rigid support columns 130. In one embodiment, the first flexible column 110 and the second flexible column 120 can be fixed together facing each other using strong adhesive, but the fixing method is not limited to this.
[0036] In one implementation, such as Figure 3 As shown, the first flexible column 110 has a first receiving groove 113 on its first side, and the second flexible column 120 has a second receiving groove 123 on its second side. When the first flexible column 110 and the second flexible column 120 are fixedly connected, they are fixed by the first side of the first flexible column 110 and the second side of the second flexible column 120 facing each other. Correspondingly, the first receiving groove 113 and the second receiving groove 123 also face each other to form an internal space between the first flexible column 110 and the second flexible column 120 to accommodate at least one rigid support column 130. Here, at least one rigid support column 130 should fit against at least a portion of the internal space between the first columns 10 to achieve a more stable support capacity.
[0037] In one embodiment, the first flexible column 110 and the second flexible column 120 have the same structural configuration. Taking the first flexible column 110 as an example, the structural configuration of the first flexible column 110 and the second flexible column 120 will be specifically described, such as... Figure 3 As shown, the system includes a first flexible column 110 comprising a column body 111 and a connecting plate 112. The column bodies 111 of the first flexible column 110 and the second flexible column 120 are fitted together, forming a column shape externally and an internal space to enclose at least one rigid support column 130. Here, the bottom end of the column body 111 is connected to a base, and the top of the column body 111 extends laterally to form a protruding side structure, which is defined as the connecting plate 112 of the first flexible column 110. In one embodiment, the connecting plates 112 of the first flexible column 110 and the second flexible column 120 are mated together and connected to a flexible beam 50.
[0038] In one embodiment, when the first post 10, the second post 20, and the flexible beam 50 are connected and fixed, a detachable adhesive structure can be used. For example, the first post 10, the second post 20, and the flexible beam 50 can be fixedly connected by Velcro, snap fasteners, or other means. This detachable structure between the first post 10, the second post 20, and the flexible beam 50 facilitates assembly and improves the flexibility and scalability of the simulated guardrail.
[0039] In one embodiment, both the first column 10 and the second column 20 are provided with a first upper support 140 and a second upper support 141, and the first upper support 140 and the second upper support 141 are fixedly connected to each other, as shown in the following figure. Figure 4 As shown, a groove structure is provided on one side of the first upper support 140 and one side of the second upper support 141, so that when the first upper support 140 and the second upper support 141 are mated and fixed, a first positioning groove 142 is formed. Thus, the top of at least one rigid support column 130 is embedded in the first positioning groove 142 for fixation. In one embodiment, the first upper support 140 and the second upper support 141 are enclosed in the internal space formed between the first flexible column 110 and the second flexible column 120. In one embodiment, the first upper support 140 and the second upper support 141 can be fixed by mating with one or two screws.
[0040] In one embodiment, both the first column 10 and the second column 20 are provided with a lower sleeve 150, specifically as follows: Figure 5 As shown, the lower sleeve 150 has a cylindrical outer surface. Simultaneously, based on the number of rigid support columns 130 specifically provided, a second positioning groove 151 is provided in the lower sleeve 150. Thus, the bottom of at least one rigid support column 130 is embedded and fixed in the second positioning groove 151. In one embodiment, the lower sleeve 150 is enclosed in the internal space formed between the first flexible column 110 and the second flexible column 120.
[0041] In one embodiment, the lower sleeve 150 is further provided with at least one magnet 152. In another embodiment, based on the specific number, shape, and size of the magnets 152, a third positioning groove 153 is provided in the lower sleeve 150 on the side opposite to the second positioning groove 151 to accommodate the magnets 152. This fixes at least one magnet 152 in the third positioning groove 153. In one embodiment, the magnet 152 can be a neodymium iron boron magnet 152 with a diameter of 36 mm, a vertical attraction force of 88 kg, and a horizontal attraction force of 28 kg to meet balance conditions.
[0042] In one embodiment, the first base 30 and the second base 40 have the same structural configuration. In one embodiment, the base includes an iron block 320 and a base 310. Specifically, as shown... Figure 6 As shown, based on the size and shape of the iron block 320, a fourth positioning groove 311 is provided on the base 310. The iron block 320 is then embedded in the fourth positioning groove 311 and can be fixedly connected using screws or glue. In this application, multiple screws can be specifically used for fixing. Here, the base 310 can be made of rubber material.
[0043] In one embodiment, a magnet 152 is provided in the lower sleeve 150 of the column, and an iron block 320 is provided on the base. In this way, when the column and the base are connected, they can be fixedly connected based on the adsorption force between the magnet 152 and the iron block 320.
[0044] In one embodiment, the surface of the flexible beam 50 is covered with a thin film layer, such as a transparent PVC film. Here, the film layer can be bonded using adhesive. In another embodiment, a reflective coating layer, such as zinc pigment paint, is provided on the surface of the film layer to achieve the metallic reflective effect of a realistic guardrail.
[0045] In one embodiment, the flexible beam 50 has a smooth plane on the side facing the first column 10 and the second column 20, and a wavy surface on the side facing away from the first column 10 and the second column 20.
[0046] In one embodiment, the first column 10, the second column 20, and the flexible beam 50 are generally made of EVA material, and their surfaces are wrapped with a polycarbonate film and galvanized. Here, EVA material is a copolymer of ethylene and vinyl acetate, with a density of 15 kg / m³, possessing good feel, high elasticity, bending resistance, and the ability to withstand large impact loads. In one embodiment, the first upper support 140, the second upper support 141, the lower sleeve 150, at least one rigid support column 130, and the base 310 of the base can be made of different types of plastic materials. By making the first column 10, the second column 20, and the flexible beam 50 flexible, damage to the vehicle and guardrail due to collisions or accidents can be avoided during testing, improving the safety of intelligent driving tests. In one embodiment, to ensure the stability and durability of the connections between the various components of the simulated guardrail, strong adhesive can be used for reinforcement, allowing it to penetrate the material and form a strong adhesive layer, thereby improving the tensile strength and firmness of the simulated guardrail.
[0047] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
