Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of traffic accidents, in particular to a deformation investigation and detection device for accident vehicles at traffic accident sites. Background Art
[0002] Vehicle deformation is a key piece of physical evidence in traffic accidents. By inspecting and testing vehicle deformation, we can gather key evidence directly related to the accident. This evidence is crucial for subsequent accident liability determination, compensation processing, and legal proceedings.
[0003] 3D laser scanners measure distances by emitting laser beams and receiving reflected light, with accuracy down to the millimeter level. This high-precision measurement capability enables it to accurately capture various details of vehicle deformation, including size, shape, and position. This is crucial for subsequent accident analysis, liability determination, and compensation processing.
[0004] Compared with traditional contact measurement, the 3D laser scanner uses a non-contact measurement method, which will not cause secondary damage to the vehicle; this is of great significance for protecting the accident scene and preserving original evidence; at the same time, non-contact measurement can also complete the measurement work more quickly and improve work efficiency.
[0005] 3D laser scanners capture 3D data of vehicle deformation and, through software processing, generate 3D models. These models visually demonstrate vehicle deformation, helping investigators better understand the accident process. Furthermore, 3D models can be used to simulate accident scenes for accident reconstruction and cause analysis.
[0006] When staff conduct deformation inspections on accident vehicles at traffic accident scenes, they usually use 3D laser scanners. However, during use, the position of the 3D laser scanner needs to be adjusted so that the 3D laser scanner can completely scan the accident vehicle at the accident scene. This process is usually adjusted manually by staff, but the 3D laser scanner takes a long time during the adjustment and scanning processes. If manual position adjustment and scanning are always used, the workload of the staff is increased. Utility Model Content

DETAILED DESCRIPTION
[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0026] like Figure 1 As shown, a deformation investigation and detection device for accident vehicles at the scene of a traffic accident comprises a mounting shell 2, self-locking wheels 1 are fixedly connected to the four corners of the lower end of the mounting shell 2, vertical plates 3 are symmetrically fixedly connected to the left and right parts of the lower inner surface of the mounting shell 2, an adjusting component 4 is provided on the inner surface of the mounting shell 2, a storage box 5 is fixedly connected to the upper side of the adjusting component 4, a lifting component 7 is provided in the inner cavity of the storage box 5, a rotating component 6 is provided on the upper side of the lifting component 7, a three-dimensional laser scanner 8 is fixedly connected to the upper side of the rotating component 6, a box cover 9 is rotatably connected to the front upper end of the storage box 5, and a multi-stage telescopic rod 10 is symmetrically fixedly connected to the front and rear parts of the lower inner surface of the mounting shell 2.
[0027] The three-dimensional laser scanner 8 is a mature technical means in the prior art. It is mainly used to scan the accident vehicle at the scene after a traffic accident, thereby obtaining deformation-related data of the accident vehicle. This solution only demonstrates its cooperation with other structures. As for the method, principle and process of scanning the accident vehicle at the scene to obtain deformation-related data of the accident vehicle, this solution will not elaborate on this.
[0028] The above-mentioned rotatable connection between the middle box cover 9 and the storage box 5 is a conventional design in the prior art. After the box cover 9 is rotated and opened, it will not hinder the three-dimensional laser scanner 8 from moving out of the storage box 5. At the same time, the storage box 5 will not be easily opened after the cover is closed. The present invention will not further elaborate on its structure and working principle.
[0029] In a specific implementation, the device is transported to the scene of the traffic accident, and then the box cover 9 is opened, the lifting assembly 7 is turned on to completely move the three-dimensional laser scanner 8 out of the storage box 5, and the rotating assembly 6 is turned on to adjust the three-dimensional laser scanner 8 to a position facing the accident vehicle at the scene of the traffic accident;
[0030] Turning on the rotating component 6 can drive the 3D laser scanner 8 to rotate, thereby adjusting the scanning angle of the 3D laser scanner 8. Turning on the adjusting component 4 can adjust the scanning height of the 3D laser scanner 8, so that the 3D laser scanner 8 can better complete the complete scan of the accident vehicle;
[0031] After the three-dimensional laser scanner 8 is used to complete the scanning work of the accident vehicle, the lifting assembly 7 is opened to store the three-dimensional laser scanner 8 back into the storage box 5, and then the box cover 9 is closed.
[0032] Specifically, in order to store the three-dimensional laser scanner 8 when it is not in use, thereby preventing the three-dimensional laser scanner 8 from being damaged, refer to Figure 4 The lifting assembly 7 includes a third motor 71, which is fixedly connected to the left portion of the lower inner surface of the storage box 5. The output end of the third motor 71 is fixedly connected to a threaded rod 73 through a coupling. The outer surface of the threaded rod 73 is threadedly connected to a slide 72. The slide 72 is slidably connected to the right side of the inner surface of the storage box 5.
[0033] Further reading Figure 5 The rotating assembly 6 includes a rotating rod 2 64, which is rotatably connected to the middle part of the upper end of the skateboard 72. The outer surface of the rotating rod 2 64 is fixedly connected to a gear 2 65. The upper end of the rotating rod 2 64 is fixedly connected to a circular plate 66. The three-dimensional laser scanner 8 is fixedly connected to the upper end of the circular plate 66. The right part of the lower end of the skateboard 72 is fixedly connected to the motor 2 61. The output end of the motor 2 61 is fixedly connected to the rotating rod 1 62 through a coupling. The upper end of the rotating rod 1 62 passes through the lower end of the skateboard 72 and extends to the upper side of the skateboard 72. The outer surface of the rotating rod 1 62 is fixedly connected to a gear 1 63, and the gear 1 63 is engaged with the gear 2 65.
[0034] In a specific implementation, after the device is transported to the traffic accident scene, the box cover 9 is opened, and the motor 3 71 is turned on to drive the threaded rod 73 to rotate forward, thereby driving the slide 72 to move upward, thereby driving the 3D laser scanner 8 to move upward until it is completely moved out of the storage box 5;
[0035] Then, the second motor 61 is turned on to rotate the first rotating rod 62, thereby rotating the first gear 63, thereby rotating the second gear 65, thereby rotating the second rotating rod 64, thereby rotating the circular plate 66, thereby rotating the three-dimensional laser scanner 8, until the three-dimensional laser scanner 8 is adjusted so that its scanning lens is facing the accident vehicle to be scanned;
[0036] By performing the above operation, the angle of the scanning lens of the 3D laser scanner 8 can be adjusted during the scanning process of the accident vehicle by the 3D laser scanner 8, so that the 3D laser scanner 8 can better perform a complete scan of the accident vehicle, thereby obtaining more accurate deformation data, and providing better assistance for subsequent traffic accident investigation and identification work;
[0037] After completing the scan of the accident vehicle, start motor three 71 to drive the threaded rod 73 to reverse, thereby driving the slide plate 72 to move downward, thereby driving the three-dimensional laser scanner 8 to move downward until it is completely moved back into the storage box 5. In this way, the three-dimensional laser scanner 8 does not need to be exposed to the external environment all the time, preventing accidental collisions and damage to its own parts.
[0038] Specifically, in order to adjust the height of the three-dimensional laser scanner 8 when scanning the accident vehicle at the scene, so as to facilitate a complete scan of the accident vehicle at the scene, refer to Figure 2 The left and right sides of the outer surface of the two-way integrated threaded rod 42 are threadedly connected to sliders 44, and the left and right parts of the upper sides of the two sliders 44 are symmetrically provided with connecting rod assemblies 45. The upper sides of the two connecting rods 45 are jointly fixedly connected to the fixing plate 46, and the storage box 5 is fixedly connected to the upper end of the fixing plate 46. The two multi-stage telescopic rods 10 are respectively fixedly connected to the middle of the front and rear sides of the lower end of the fixing plate 46; the two vertical plates 3 are jointly fixedly connected to the limit rod 43 at the front and rear of the opposite ends, and the two sliders 44 are slidably connected to the outer surfaces of the two limit rods 43; the left and right sides of the outer surface of the two-way integrated threaded rod 42 are threadedly connected to sliders 44
[0039] Further reading Figure 3 The connecting rod assembly 45 includes two connecting rods 451, which are rotatably connected to the front and rear ends of the left slider 44 respectively. The front and rear sides of the middle part of the lower end of the fixing plate 46 are symmetrically fixedly connected with a fixing block 452. The inner surfaces of the two fixing blocks 452 are commonly fixedly connected with a round rod 453. The two connecting rods 451 are rotatably connected to the front and rear sides of the outer surface of the round rod 453 respectively.
[0040] In a specific implementation, when the three-dimensional laser scanner 8 is scanning a traffic accident vehicle, the motor 1 41 can be turned on to drive the bidirectional integrated threaded rod 42 to rotate. Since the thread grooves on the left and right sides of the outer surface of the bidirectional integrated threaded rod 42 are opened in opposite directions, the rotation of the bidirectional integrated threaded rod 42 drives the two sliders 44 to move toward each other or away from each other at the same time. The two limit rods 43 can limit the movement of the two sliders 44.
[0041] The two sliders 44 move toward each other simultaneously, forcing the four connecting rods 451 to rotate toward the vertical state, thereby driving the fixing plate 46 to move upward;
[0042] On the contrary, the two sliders 44 move away from each other at the same time, forcing the four connecting rods 451 to rotate toward the horizontal state, thereby driving the fixing plate 46 to move downward;
[0043] The fixed plate 46 moves upward or downward, driving the three-dimensional laser scanner 8 to move upward or downward, thereby adjusting the height of the scanning lens of the three-dimensional laser scanner 8, thereby further helping the three-dimensional laser scanner 8 to better perform a complete scan of the accident vehicle, thereby obtaining more accurate deformation data.
[0044] When the adjustment assembly 4 is opened to move the fixed plate 46 up and down, the two multi-stage telescopic rods 10 will provide support to the fixed plate 46, making the up and down movement of the fixed plate 46 more stable. At the same time, the two multi-stage telescopic rods 10 will extend and retract as the fixed plate 46 moves up and down, and will not hinder the up and down movement of the fixed plate 46.
[0045] It should be noted that the specific installation method, circuit connection method and control method of motor 1 41, motor 2 61, motor 3 71 and three-dimensional laser scanner 8 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
[0046] The working principle of this utility model is:
[0047] After the device is transported to the traffic accident scene, the box cover 9 is opened, and the motor 3 71 is turned on to drive the threaded rod 73 to rotate forward, thereby driving the slide 72 to move upward, thereby driving the 3D laser scanner 8 to move upward until it is completely moved out of the storage box 5;
[0048] Then, the second motor 61 is turned on to rotate the first rotating rod 62, thereby rotating the first gear 63, thereby rotating the second gear 65, thereby rotating the second rotating rod 64, thereby rotating the circular plate 66, thereby rotating the three-dimensional laser scanner 8, and adjusting the angle of the scanning lens of the three-dimensional laser scanner 8;
[0049] Turn on the motor 1 41 to drive the bidirectional integrated threaded rod 42 to rotate, driving the two sliders 44 to move towards each other or away from each other at the same time. The two sliders 44 move away from each other at the same time, forcing the four connecting rods 451 to rotate to a horizontal state, thereby driving the fixed plate 46 to move downward. The two sliders 44 move away from each other at the same time, forcing the four connecting rods 451 to rotate to a horizontal state, thereby driving the fixed plate 46 to move downward. The fixed plate 46 moves upward or downward, driving the three-dimensional laser scanner 8 to move upward or downward, thereby adjusting the height of the scanning lens of the three-dimensional laser scanner 8;
[0050] After completing the scanning of the accident vehicle, the motor 3 71 is turned on to drive the threaded rod 73 to reverse, thereby driving the slide plate 72 to move downward, thereby driving the three-dimensional laser scanner 8 to move downward until it is completely moved back into the storage box 5.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
