[0072] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0073] As described in the background section, current large target objects such as spur trailers are mainly made using inflatable methods. Due to the large volume and internal air pressure inside the vehicle's front, they are prone to damaging the vehicle being tested during testing. Therefore, this application provides a new model vehicle for testing that solves the problem of model vehicles in related technologies easily damaging the vehicle being tested during testing.

[0074] The following will provide a detailed description and explanation of the model vehicle used for testing in this application, with reference to the accompanying drawings.

[0075] See Figures 1 to 3 As shown in the figure, this application embodiment provides a model car. The model car includes a front end (hereinafter referred to as the front end) and a rear end 20. The front end 10 includes a flexible support column 11 and multiple flexible support plates 12, with the flexible support column 11 supporting the multiple flexible support plates 12.

[0076] In this embodiment, the front of the model car 10 includes flexible support columns 11 and multiple flexible support plates 12. During actual assembly, the flexible support plates 12 form the external frame of the front of the car 10, and the flexible support columns 11 are supported between the multiple flexible support plates 12, providing support to maintain the external shape of the front of the car 10. After assembly, the front of the car 10 is a flexible structure, making it less likely to cause damage to the test vehicle when it collides with the front of the car 10.

[0077] For example, the flexible support plate 12 in this embodiment can be two, three, or more than three pieces. This application's Figure 2The diagram illustrates the case where there are two flexible support plates 12. Specifically, in some embodiments, the flexible support plate 12 includes a first flexible support plate 12a and a second flexible support plate 12b spaced apart. The first flexible support plate 12a and the second flexible support plate 12b are vertically arranged on opposite sides of the front of the vehicle 10, with a gap 13 between them. It is understood that in this embodiment, "the first flexible support plate 12a and the second flexible support plate 12b are vertically arranged on opposite sides of the front of the vehicle 10" means that the first flexible support plate 12a and the second flexible support plate 12b are vertically arranged on the left and right sides of the front of the vehicle 10, where left and right refer to the left and right sides when the model vehicle is moving. In this application, the flexible support plate 12 is configured as a first flexible support plate 12a and a second flexible support plate 12b, and these are vertically arranged on the left and right sides of the front of the vehicle 10, which forms the main shape of the front of the vehicle 10, resulting in a simple structure that is easy to implement.

[0078] During installation, the two ends of the flexible support column 11 are connected to the first flexible support plate 12a and the second flexible support plate 12b, respectively, forming a relatively stable front end 10 structure. Optionally, in this embodiment, the flexible support column 11 is bonded to the flexible support plate 12. This configuration makes it easier for the model car to disintegrate when it collides with the vehicle being tested, and less likely to damage the vehicle being tested. In actual connection, the flexible support column 11 and the flexible support plate 12 in this embodiment can be bonded with glue or with Velcro.

[0079] In some embodiments, in order to improve the assembly efficiency of the front end 10, a first positioning part 1201 is provided on the side of the first flexible support plate 12a near the second flexible support plate 12b, and a second positioning part 1202 is provided on the side of the second flexible support plate 12b near the first flexible support plate 12a. In actual connection, the two ends of the flexible support column 11 are respectively connected to the first positioning part 1201 and the second positioning part 1202. In this way, the connection position of the flexible support column 11 can be quickly determined, which facilitates the improvement of the production efficiency of the model car.

[0080] For example, the first positioning part 1201 includes a first positioning hole or a first positioning groove. In actual installation, the first end of the flexible support column 11 is inserted into the first positioning hole or the first positioning groove, and then fixed with glue. Optionally, the second positioning part 1202 includes a second positioning hole or a second positioning groove. In actual installation, the second end of the flexible support column 11 is inserted into the second positioning hole or the second positioning groove, and then fixed with glue. The structure is simple and the assembly is convenient.

[0081] In some embodiments, the flexible support column 11 includes an inflatable column. During use, inflating the column allows the first flexible support plate 12a and the second flexible support plate 12b to be pushed to their respective positions. Simultaneously, by setting the flexible support column 11 as an inflatable column, after use of the model car, the gas inside the column can be released, and then the first flexible support plate 12a and the second flexible support plate 12b can be stacked together. The structure is simple and easy to store. Of course, in other embodiments of this application, the flexible support column 11 can also be a foam column, a rubber column, etc. Any other variations within the scope of this application's concept are within the protection scope of this application.

[0082] Optionally, the flexible support columns 11 may include multiple columns to facilitate stable support for the first flexible support plate 12a and the second flexible support plate 12b. Exemplarily, the flexible support columns 11 may be two, three, four, five, or more. Figure 2 The figure shows the case when there are eight flexible support columns 11. The specific setting and selection are based on the actual structural strength requirements, and no specific limitation is made in this application.

[0083] Combination Figure 3 As shown, in some embodiments, the flexible support plate 12 includes a flexible support plate body 121 and a support frame 122. The support frame 122 is connected to the flexible support plate body 121 to at least support the flexible support plate body 121. In this embodiment, by setting the flexible support plate 12 as a combination structure of the flexible support plate body 121 and the support frame 122, both the flexibility and structural strength of the flexible support plate 12 can be taken into account, avoiding damage to the test vehicle caused by the model vehicle.

[0084] Furthermore, in some embodiments, the flexible support plate 121 is provided with a mounting groove 1211, and the support frame 122 is glued or embedded in the mounting groove 1211. This application, by providing a mounting groove 1211 on the flexible support plate 121 and correspondingly gluing or embedding the support frame 122 into the mounting groove 1211, has a simple structure and is easy to install.

[0085] In some embodiments, the support frame 122 includes multiple support pipes 1221 and multiple pipe joints 1222. The multiple support pipes 1221 are connected by the multiple pipe joints 1222 to form a planar frame structure. The inclusion of support pipes 1221 can reduce the weight of the support frame 122 to a certain extent, and the connection of multiple support pipes 1221 with pipe joints 1222 makes assembly convenient and quick. At the same time, the planar frame structure is suitable for supporting the flexible support plate 12. For example, the support pipes 1221 in this embodiment are PVC pipes. Of course, in other embodiments of this application, the support frame 122 can also be formed by overlapping solid columns. Any other variations within the concept of this application are within the protection scope of this application.

[0086] In some embodiments, the flexible support plate 121 includes expanded polyethylene (EPE) sheets. The EPE has a honeycomb-like bubble structure inside; when impacted or compressed, the bubbles can absorb the impact force through deformation, effectively buffering external pressure and protecting the tested vehicle from damage. Furthermore, EPE has low density and light weight, good corrosion resistance, and is not easily corroded by acids, alkalis, greases, or other chemicals. It has a wide temperature resistance range (generally -60℃ to 80℃) and stable performance in high and low temperature environments, without significant deformation or failure due to temperature changes. It is suitable for the complex environments of long-distance transportation, reducing the transportation cost of the model car and extending its service life to some extent. Optionally, the flexible support plate 121 includes one or more support bodies 1212. When the flexible support plate 121 includes multiple support bodies 1212, adjacent support bodies 1212 are bonded together. In this embodiment, the support body 1212 is set to one or more pieces, which can be selected and processed according to the existing EPE size to obtain a suitable vehicle head 10. Figure 3 As shown, Figure 3 The diagram shows the case when the support 1212 consists of two blocks.

[0087] Furthermore, in this embodiment, a protective layer 123 is provided on the outer surface of the flexible support plate 12 facing the model car. This protective layer 123 protects the flexible support plate 12 and improves the service life of the model car in this application. Optionally, the protective layer 123 is attached to the flexible support plate 12 with adhesive or Velcro.

[0088] For example, the protective layer 123 in this embodiment includes a knife-coated fabric, also known as a knife-coated cloth, which is a high-strength, high-performance PVC-coated fabric. It is made by uniformly coating a PVC slurry onto the surface of a base fabric through a knife-coating process. Knife-coated fabric has extremely high physical strength. Its base fabric is mostly woven from high-strength polyester fibers (polyester), and combined with the tight adhesion of the knife-coated coating, the overall tear resistance and tensile strength of the fabric far exceed those of ordinary tarpaulins or canvases. Even under the action of strong winds, pulling, and other external forces, knife-coated fabric is not easily damaged and has extremely high durability. The surface PVC coating is tough and has excellent abrasion resistance. It is not easy to pill, flake, or wear when used for a long time or frequently in contact with object surfaces. At the same time, knife-coated fabric also has good waterproof and moisture-proof properties, sealing properties, UV resistance, acid resistance, and corrosion resistance, which can effectively improve the service life of the model car in this application.

[0089] Combination Figures 1 to 3 As shown, the front of the car 10 in this application also includes a front cover 14, which covers the front end and top of the front of the car 10 and is connected to the flexible support plate 12. Specifically, the front cover 14 is connected to the first flexible support plate 12a and the second flexible support plate 12b respectively, which can cover the front side and top of the gap 13, making the shape of the model car closer to that of a real vehicle.

[0090] Optionally, the front of the vehicle 10 also includes a first cover 15, which is disposed on the side of the flexible support plate 12 facing the outer surface of the front of the vehicle 10 and connected to the flexible support plate 12. The first cover 15 can cover the left and right sides of the front of the vehicle 10, making the shape of the model car closer to that of a real vehicle.

[0091] Furthermore, the front cover 14 and the flexible support plate 12, as well as the first cover 15 and the flexible support plate 12, are all bonded together, resulting in a simple structure that is easy to assemble.

[0092] Furthermore, the front cover 14 and / or the first cover 15 include a metal layer (not shown in the figure), that is, at least one of the front cover 14 and the first cover 15 includes a metal layer. It is understood that the metal layer here is a metal film coated, sputtered, or woven onto the front cover 14 or the first cover 15. The metal layer can be a copper layer, an aluminum layer, an iron layer, etc. This metal layer can simulate the radar reflection waves of a real vehicle, so that the model car can be identified as a real vehicle under visual, millimeter-wave radar, or lidar recognition.

[0093] In some embodiments, the outer surface of the front cover 14 and / or the first cover 15 is provided with a first marking pattern 16 characterizing the vehicle characteristics of the model car used for testing. The first marking pattern 16 includes wheels, headlights, front fascia features, sheet metal seams, etc., so that the test vehicle can visually identify the model car as a real vehicle.

[0094] As can be seen from the above embodiments, during use, inflating the inflatable column pushes the first flexible support plate 12a and the second flexible support plate 12b to their respective positions, simultaneously opening the front cover 14 to form the front of the vehicle 10. Because the first flexible support plate 12a and the second flexible support plate 12b are made of low-density pearl cotton board, and the inflatable column is lightweight, the front of the vehicle 10 will not cause damage to the tested vehicle after an impact. After use, deflating the inflatable column allows the first flexible support plate 12a and the second flexible support plate 12b to be stacked together, and the front cover 14 to be folded, facilitating storage, organization, and transportation of equipment between different testing sites.

[0095] Meanwhile, due to the softness of the pearl cotton board, especially in large-sized cases, its rigidity is insufficient, easily causing the model to collapse. To solve this problem, a mounting groove 1211 is provided on the flexible support plate 121, and a support frame 122 is set in the mounting groove 1211. After the support frame 122 is installed in the mounting groove 1211, the support frame 122 and the flexible support plate 121 are connected into a whole by adhesive. The outer surface of the flexible support plate 12 is covered with a layer of scraped cloth, which not only further improves the rigidity of the flexible support plate 12, but also improves its wear resistance due to unavoidable collisions during testing. Since the testing site environment is uncertain, some testing sites may be relatively humid, and the scraped cloth can be waterproof and moisture-proof, preventing moisture penetration.

[0096] Combination Figures 1 to 6 As shown, the model car used for testing in this embodiment also includes a rear end 20, which is adhesively connected to the front end 10. Optionally, the rear end 20 and the front end 10 are attached using Velcro. In the event of a collision during testing, the front end 10 and the rear end 20 can be quickly separated, avoiding damage to the test vehicle and the model car itself.

[0097] Furthermore, the rear of the vehicle 20 includes a flexible support frame 21, which comprises multiple support units 211 connected sequentially along the length of the model vehicle. Exemplarily, the support units 211 can be two, three, or more; no specific limitation is made in this application. By providing a flexible support frame 21 with multiple support units 211 at the rear of the vehicle 20, this application can simulate trailer structures of different lengths, making it more suitable for performance testing of the vehicle under test.

[0098] In some embodiments, the support unit 211 includes a third flexible support plate 2111, a fourth flexible support plate 2112, a fifth flexible support plate 2113, and a sixth flexible support plate 2114. The third flexible support plate 2111 and the fourth flexible support plate 2112 are vertically disposed on opposite sides of the rear of the vehicle 20 (the left and right sides of the rear of the vehicle 20) and extend along the length of the model vehicle. The third flexible support plate 2111 has a first connecting end 2111a disposed away from the front of the vehicle 10, the fourth flexible support plate 2112 has a second connecting end 2112a disposed away from the front of the vehicle 10, the fifth flexible support plate 2113 connects between the first connecting end 2111a and the second connecting end 2112a and forms a support cavity 2115 with the third flexible support plate 2111 and the fourth flexible support plate 2112, and the sixth flexible support plate 2114 is supported within the support cavity 2115.

[0099] In this embodiment, the support unit 211 is constructed from a third flexible support plate 2111, a fourth flexible support plate 2112, a fifth flexible support plate 2113, and a sixth flexible support plate 2114. It has a simple structure and a certain strength.

[0100] Furthermore, in this embodiment, two adjacent support units 211 are connected by Velcro; optionally, the third flexible support plate 2111 and the fifth flexible support plate 2113 are connected by Velcro; optionally, the fourth flexible support plate 2112 and the fifth flexible support plate 2113 are connected by Velcro; optionally, the sixth flexible support plate 2114 and the third flexible support plate 2111 are connected by Velcro; optionally, the sixth flexible support plate 2114 and the fourth flexible support plate 2112 are connected by Velcro; optionally, the sixth flexible support plate 2114 and the fifth flexible support plate 2113 are connected by Velcro. In the event of a collision during testing, this allows for rapid separation of the support units 211, preventing damage to the test vehicle and the soft model vehicle itself.

[0101] Furthermore, the sixth flexible support plate 2114 includes a first flexible support block 2114a and a second flexible support block 2114b. The two ends of the first flexible support block 2114a are connected to the third flexible support plate 2111 and the fourth flexible support plate 2112, respectively; the second flexible support block 2114b is connected to the first flexible support block 2114a in a cross shape via a slot 2114c, and the second flexible support block 2114b is connected to at least the fifth flexible support plate 2113. This arrangement facilitates improved structural stability of the support unit 211.

[0102] Furthermore, the rear of the vehicle 20 also includes a flexible connecting plate 22, which is bonded to both the front of the vehicle 10 and the flexible support frame 21. In the event of a collision during testing, this facilitates rapid separation between the front of the vehicle 10 and the rear of the vehicle 20, preventing damage to the test vehicle and the soft model vehicle itself.

[0103] Furthermore, the front of the vehicle 10 protrudes from the top surface of the flexible support frame 21, and the top surface of the flexible connecting plate 22 is flush with the top surface of the front of the vehicle 10, which is more suitable for simulating a large trailer structure on the road.

[0104] Optionally, the third flexible support plate 2111, the fourth flexible support plate 2112, the fifth flexible support plate 2113, the sixth flexible support plate 2114, and the flexible connecting plate 22 all include pearl cotton boards. The pearl cotton board has a honeycomb-like bubble structure inside. When subjected to impact or compression, the bubbles can absorb the impact force through deformation, effectively buffering external pressure and protecting the tested vehicle from damage. Furthermore, pearl cotton has low density and light weight, good corrosion resistance, and is not easily corroded by acids, alkalis, greases, or other chemicals. It has a wide temperature resistance range (generally -60℃ to 80℃), and its performance is stable in high and low temperature environments. It will not significantly deform or fail due to temperature changes, making it suitable for the complex environments of long-distance transportation. This can reduce the transportation cost of the model car and, to a certain extent, extend its service life.

[0105] Furthermore, a second car cover 23 is provided on both the outer side of the flexible support frame 21 facing the model car and on the top surface of the flexible support frame 21. This second car cover 23 covers the outer periphery, sides, and top surface of the flexible support frame 21, making the model car's shape closer to a real vehicle. It is understood that the outer side of the flexible support frame 21 referred to here means the side-facing surface of the flexible support frame 21.

[0106] Furthermore, the second car cover 23 and the flexible support frame 21 are bonded together on the sides facing the outside of the model car and the top surface of the flexible support frame 21, which is simple in structure and easy to assemble.

[0107] Furthermore, the second cover 23 includes a metal layer (not shown in the figure). It is understood that this metal layer is a metal film coated, sputtered, or woven onto the second cover 23. This metal layer can be a copper layer, an aluminum layer, an iron layer, etc. The presence of this metal layer simulates the radar reflection waves of a real trailer, enabling the software to identify the target trailer as a real trailer regardless of whether it is detected by vision, millimeter-wave radar, or lidar.

[0108] In some embodiments, the outer surface of the second cover 23 is provided with a second identifying pattern characterizing the vehicle characteristics of the model vehicle. This second identifying pattern includes wheels, headlights, front fascia features, and sheet metal seams, enabling the test vehicle to visually identify it as a real trailer.

[0109] In some embodiments, at least one of the sides of the flexible support frame 21 facing the outside of the model vehicle and the top surface of the flexible support frame 21 is a concave-convex surface (not shown in the figure). For example, the concave-convex surface can be a corrugated surface. The concave-convex surface can better absorb radar waves and better simulate the radar reflection characteristics of a real trailer.

[0110] In some embodiments, the model car also includes headlights with reflectors 30 attached to them, so that the test vehicle can visually identify the model car as a real vehicle.

[0111] In other words, the flexible support plates (including the third flexible support plate 2111, the fourth flexible support plate 2112, the fifth flexible support plate 2113, the sixth flexible support plate 2114, and the flexible connecting plate 22) of the rear of the vehicle in this application are sewn with Velcro on their mating surfaces, so that the flexible support plates can be connected together by Velcro. The second car cover 23 is attached to the flexible support frame 21 and fixed with Velcro to form a soft trailer rear end that imitates the characteristics of a real trailer rear end. The second car cover 23 is printed with a second marking pattern 24 that simulates the characteristics of a real vehicle. The purpose of using Velcro to connect the various parts is to allow the stress-bearing parts to disintegrate quickly after a collision, reducing damage to the target object and the test vehicle, and to allow for quick reassembly after a collision for the next round of testing.

[0112] The flexible support frame 21 includes multiple support units 211, which can form the overall outline of the rear of the vehicle 20. A sixth flexible support plate 2114 is arranged in the middle of each square of the support unit 211 to strengthen the overall outline and prevent the vehicle model from collapsing. The third flexible support plate 2111, the fourth flexible support plate 2112, and the fifth flexible support plate 2113 are positioned by their edge surfaces to prevent large deviations in model building or poor consistency of the models built each time.

[0113] The sixth flexible support plate 2114 is mainly composed of the first flexible support block 2114a and the second flexible support block 2114b. The two are connected by the slot 2114c to form a cross-shaped mechanism. It is connected to the third flexible support plate 2111, the fourth flexible support plate 2112 and the fifth flexible support plate 2113 at the mating surface by Velcro, which plays the role of strengthening the frame of the rear of the vehicle 20.

[0114] The second vehicle cover 23 features second identifying patterns 24 that represent vehicle characteristics, such as wheels, headlights, front fascia features, and sheet metal seams. Reflective strips 30 are also affixed to the headlights and other areas to visually identify the test vehicle as a real trailer. Furthermore, the inner layer of the second vehicle cover 23 is woven with a metallic layer to simulate the radar reflection waves of a real trailer, ensuring that the target trailer in this software can be identified as a real trailer by visual, millimeter-wave radar, or lidar detection methods.

[0115] Furthermore, the model car setup described in this application can also be applied to other large soft objects simply by changing the shape of each part and the pattern on the skin.

[0116] Based on the above embodiments, it can be seen that the model car of this application has at least the following technical effects:

[0117] (1) The model vehicle of this application fills the gap in the current intelligent driving test, which lacks large-scale operation vehicles commonly found on the road, and completes the test scenario.

[0118] (2) Based on the characteristics of each part of the vehicle, the model car adopts a segmented design, which facilitates the rapid disintegration of the target object after a collision, thus avoiding damage to the test vehicle. Specifically, this application uses an inflatable column and pearl cotton board to connect the large-sized front part of the car, while the rear part 20 is not large in height, making it easy to assemble. At the same time, the front and rear parts are connected with Velcro, so that the target object can quickly disintegrate when the test vehicle collides with it (the front of the car can be knocked away, and the rear of the front can be quickly disintegrated). This not only avoids damage to the test vehicle but also prevents damage to the target object, facilitating its continued use in the next test. This method also shortens the assembly time and improves testing efficiency.

[0119] (3) The vehicle features are expressed through a car cover, enabling the vehicle to be identified as a real trailer by visual inspection, LiDAR, and millimeter-wave radar. This application uses patterns printed on the car cover to express more detailed features of the vehicle, such as wheels, headlights, front fascia features, and sheet metal seams. Reflective materials are also affixed to the headlights and other areas, allowing the test vehicle to be visually identified as a real trailer. Furthermore, the car cover has a metallic layer that simulates the radar reflection waves of a real trailer, ensuring the model vehicle can be identified as a real trailer by visual inspection, millimeter-wave radar, and LiDAR.
