Description

Technical Field

[0001] This utility model relates to the field of TT technology, and in particular to a multi-scenario collision simulation test device for intelligent driving vehicles. Background Technology

[0002] With the rapid development of intelligent driving technology, vehicle safety performance testing has become particularly important. Crash testing, as a core means of verifying a vehicle's passive safety performance, is crucial to ensuring that intelligent driving vehicles effectively protect occupants in various complex traffic environments. Existing intelligent driving vehicle crash testing equipment mainly uses fixed tracks or multi-station test benches, capable of simulating standard collision scenarios such as frontal, side, and rear-end collisions, meeting basic safety testing requirements.

[0003] In practical applications, the impact angles of these existing vehicle collision devices are often fixed or can only be adjusted within a limited range, making it impossible to realistically reproduce the diverse and complex collision angles in real traffic environments. In actual road traffic, vehicles may experience accidents with various non-standard angles, such as oblique collisions and offset collisions. Traditional devices are unable to effectively simulate these situations, thus limiting the coverage of test scenarios and the comprehensive evaluation of safety performance. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined Figures 1-6 This invention describes a multi-scenario collision simulation test device for intelligent driving vehicles.

[0026] In one embodiment, a multi-scenario collision simulation test device for intelligent driving vehicles includes: a drive chassis 100, a guide rail 200 slidably connected to the bottom of the drive chassis 100, and a plurality of impact plates 110 disposed on one side of the drive chassis 100; and an adjusting collision mechanism 300, which is disposed on one side of the drive chassis 100 for adjusting multi-angle collision simulation. The adjusting collision mechanism 300 includes a support seat 310 disposed on the top of the drive chassis 100, an adjusting buffer assembly 320 disposed on the outer side of the support seat 310, and an adapter assembly 330 disposed on one side of the plurality of impact plates 110.

[0027] In this embodiment, the adjustable buffer component 320 can flexibly change the attitude angle of the impact plate 110 to simulate multi-angle and multi-directional collision scenarios, enabling intelligent driving vehicles to conduct safety performance verification in a more complex environment that is closer to actual traffic accidents, thereby improving the comprehensiveness and realism of the test. In addition, the adjustable buffer component 320 plays an effective buffering role during the collision, reducing the impact on the drive chassis 100 and the overall test platform, significantly extending the service life of the equipment. The adapter components 330 on the sides of the multiple impact plates 110 can flexibly adjust the collision area according to the test requirements to meet the simulation requirements of different collision objects and parts, and improve the accuracy of collision energy distribution and the representativeness of the test results.

[0028] It should be noted that existing vehicle crash testing equipment typically includes basic components such as a drive unit, a crash target, a guide rail 200, a sensor acquisition system, and a shock absorption structure. The drive unit is used to control the trajectory and speed of the vehicle under test or the crash target, ensuring the controllability and repeatability of the crash process;

[0029] The adjustable buffer assembly 320 is made of elastic or cushioning material, which can effectively absorb impact energy. Its adjustment mechanism design ensures the stability and accuracy of the adjustment process, preventing abnormal operation of the drive chassis 100 or the impact plate 110. The adapter assembly 330 has a compact structure, is securely installed, and supports rapid adjustment of the collision area without interfering with the motion trajectory and attitude of the impact plate 110. It will not affect the normal operation and accuracy stability of the overall testing equipment during various collision simulations, meeting the stringent requirements of multi-scenario collision testing for intelligent driving vehicles.

[0030] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the adjustable buffer assembly 320 includes a connecting plate 321 disposed on one side of the support base 310. Two sealing tubes 322 are fixedly installed on one side of the support base 310. Two piston rods 323 are fixedly installed on one side of the connecting plate 321. One end of each piston rod 323 is slidably connected to the two sealing tubes 322. An adjusting gear plate 329 is rotatably installed on the top of the drive chassis 100. The support base 310 is fixedly connected to the adjusting gear plate 329.

[0031] In this embodiment, the sealing tube 322 is filled with damping silicone oil. The reciprocating sliding of the piston rod 323 within the sealing tube 322 achieves a buffering and damping effect during the impact process, effectively absorbing and dispersing the impact force generated by the collision, and significantly reducing the impact load on the support base 310 and the drive chassis 100. It is used in conjunction with the adjusting gear 329 rotatably mounted on the top of the drive chassis 100. By adjusting the rotation of the gear 329, the support base 310 and the connecting plate 321 are linked, thereby achieving precise adjustment of the impact angle.

[0032] A hydraulic cylinder 3211 is fixedly installed on the top of the drive chassis 100. A toothed plate 3210 is fixedly installed on the output end of the hydraulic cylinder 3211. One side of the toothed plate 3210 is meshed with the adjusting toothed plate 329.

[0033] In this embodiment, the hydraulic cylinder 3211 drives the toothed plate 3210 to move, and the toothed plate 3210 meshes with the adjusting toothed disc 329, thereby achieving precise rotation of the adjusting toothed disc 329, which can adjust the impact angle and ensure the accuracy and repeatability of the angle adjustment.

[0034] A first spring 324 is fixedly installed inside the sealing tube 322. The other end of the first spring 324 is fixedly connected to the piston rod 323. A connecting tube 326 is fixedly installed inside the piston rod 323.

[0035] In this embodiment, the elastic restoring force of the first spring 324 is used to enable the piston rod 323 to effectively buffer during the impact and automatically return to its original position after the external force is eliminated, thus ensuring the stable sliding and position reset of the piston rod 323.

[0036] A sealing box 325 is fixedly installed on one side of the connecting plate 321, and the other end of the connecting pipe 326 inside the two piston rods 323 extends out of the piston rods 323 and is fixedly connected to the sealing box 325.

[0037] In this embodiment, the connecting pipe 326 serves as a narrow channel, allowing the damping silicone oil to slowly flow into the sealed box 325 during the sliding of the piston rod 323. Through the restricted flow of the oil, effective damping of the piston rod 323's movement is achieved, further enhancing the buffering performance and shock absorption effect of the regulating buffer assembly 320, and improving the equipment's ability to absorb impacts.

[0038] A piston plate 327 is slidably installed inside the sealing box 325. The piston plate 327 is located on one side of the two connecting pipes 326. A second spring 328 is fixedly installed on the other side of the piston plate 327. The other end of the second spring 328 is fixedly connected to the inner wall of the sealing box 325.

[0039] In this embodiment, when the damping silicone oil is squeezed into the sealing box 325, the oil pushes the piston plate 327 to move, thereby squeezing the second spring 328. After the impact ends, the second spring 328 can reset the piston plate 327 and the entered damping silicone oil.

[0040] like Figure 2 , Figure 3 and Figure 5 As shown, the adapter component 330 includes two mounting frames 331 fixedly installed on the other side of the connecting plate 321, and two mounting blocks 332 fixedly installed on one side of the impact plate 110. The two mounting blocks 332 are respectively engaged with the interior of the two mounting frames 331.

[0041] In this embodiment, the impact plate 110 can be securely and quickly detached from the connecting plate 321, which facilitates the flexible replacement of impact plates 110 of different sizes and shapes according to test requirements, thereby achieving precise adjustment of the impact area. This modular snap-fit ​​method not only ensures the firmness of the connection, but also improves the maintenance convenience and applicability of the test equipment.

[0042] The toothed plate 3210 is set in an arc shape, and the edges of the impact plate 110 are all set to rounded corners.

[0043] In this embodiment, the arc-shaped toothed plate 3210 can increase the contact area with the adjusting toothed plate 329 and improve contact stability, while the rounded edges of the impact plate 110 can effectively reduce the local impact stress during collision and reduce the risk of material fatigue and damage.

[0044] Working principle: The drive chassis 100 moves along the guide rail 200, causing the impact plate 110 to collide with the test vehicle. The collision angle is dynamically controlled by the collision adjustment mechanism 300. The hydraulic cylinder 3211 drives the toothed plate 3210 to mesh with the adjusting toothed disc 329, precisely adjusting the posture of the impact plate 110 to achieve multi-angle and multi-directional collisions. During the collision, the damping buffer assembly 320 is filled with damping silicone oil, which, together with the first spring 324 and the second spring 328, and the synergistic effect of the piston rod 323, connecting pipe 326, sealing pipe 322 and sealing box 325, effectively buffers and absorbs the impact force, ensuring the stability and durability of the support base 310 and the drive chassis 100 structure. Meanwhile, the buffer system has an automatic reset function to ensure that the impact plate 110 quickly returns to its initial state after each collision, supporting continuous and efficient test cycles. The adapter component 330 can be connected and removed from the mounting block 332 module through the mounting frame 331, allowing for quick replacement and adjustment of the impact area of ​​the impact plate 110 to simulate collision objects of different sizes and types, improve the accuracy of collision energy distribution, and enhance the representativeness and diversity of the test.

[0045] It should be noted that the drive chassis and hydraulic cylinders mentioned above are all components with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the drive chassis and hydraulic cylinders can be powered by built-in power supply or mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
