[0028] Please see Figure 1 and Figure 2 This application provides a vehicle chassis inspection device 101, which includes a bracket 10, a base 20, and a camera assembly 30. The camera assembly 30 is mounted on the bracket 10 and used to take pictures of the vehicle chassis 102. The base 20 is connected to the bracket 10 and used to mount it to a supporting surface. The mounting angle of the bracket 10 relative to the base 20 is adjustable. It should be noted that the supporting surface includes, but is not limited to, the ground or the bottom of a pit. When the base 20 is mounted on an uneven ground or the bottom of a pit, the camera assembly 30 can be adjusted to be horizontal by adjusting the mounting angle of the bracket 10 relative to the base 20, so that the camera assembly 30 faces the vehicle chassis 102.
[0029] Furthermore, the bracket 10 includes a connecting plate 11, and the base 20 includes a plurality of support legs 21 spaced apart on the connecting plate 11. One end of each support leg 21 is connected to the connecting plate 11, and the other end is used to connect to a support plane, and the distance between the connecting plate 11 and the support plane can be adjusted. Thus, by adjusting the distance between the connecting plate 11 and the support plane at different support legs 21, the installation angle of the connecting plate 11 relative to the base 20 can be adjusted.
[0030] Optionally, the support column 21 can be threaded to the connecting plate 11, so that the distance between the connecting plate 11 and the supporting plane can be adjusted by screwing the support column 21; or, the support column 21 can also be configured as a telescopic link structure.
[0031] The bracket 10 also includes a support beam 12 and a mounting frame 13. The mounting frame 13 is used to mount the camera assembly 30, and the mounting frame 13 and the connecting plate 11 are respectively connected to both ends of the support beam 12. The support beam 12, the mounting frame 13, and the connecting plate 11 are all formed by welding square tubes to improve the structural strength of the bracket 10.
[0032] For example, in one embodiment, the number of support legs 21 is configured to be two, and the two support legs 21 are located on both sides of the support beam 12 along the width direction of the vehicle chassis.
[0033] The mounting frame 13 has a mounting surface 14 on one side of the connecting plate 11, which faces the vehicle chassis. The camera assembly 30 is mounted on the bracket 10, and at least a portion of the camera assembly 30 is exposed at the mounting surface 14. In this way, the camera assembly 30 is integrated inside the mounting frame 13, making the vehicle chassis inspection device 101 look cleaner and more aesthetically pleasing.
[0034] The number of camera components 30 is configured to be multiple, and the multiple camera components 30 are distributed at intervals along the length of the mounting frame 13. This helps to ensure that the camera components 30 form a wider and more suitable shooting angle for the vehicle chassis 102, thereby helping to ensure the shooting effect of the vehicle chassis 102.
[0035] Furthermore, such as Figure 3 As shown, multiple camera assemblies 30 are arranged at equal intervals along the length of the mounting frame 13. For example, the number of camera assemblies 30 is configured to be five, and the five camera assemblies 30 are arranged at equal intervals along the length of the mounting frame 13. In actual use, the length of the mounting frame 13 is consistent with the width of the vehicle chassis 102.
[0036] like Figures 2 to 4 As shown, the side wall of the mounting frame 13 is provided with a plug-in interface 15, which is used for wiring connection. Optionally, the mounting frame 13 is provided with plug-in interfaces 15 at both ends along its length.
[0037] The camera assembly 30 includes a detection camera 31 and a camera light source 32, with the camera light source 32 surrounding the outer periphery of the detection camera 31.
[0038] Please see Figure 4 The vehicle chassis detection device 101 also includes a limit switch 40, which is electrically connected to the camera assembly 30 and is used to enable the camera assembly 30 to take pictures.
[0039] Please see Figure 5This application also provides an automobile chassis inspection system, which includes a controller 200, a vision processing module 300, and the automobile chassis inspection device 101 described in any of the above embodiments. The controller 200 and the camera assembly 30 are respectively connected to the vision processing module 300. The controller 200 is used to store preset image templates, and the vision processing module 300 is used to compare and verify the automobile chassis photos taken by the camera assembly 30 with the preset image templates stored in the controller 200. In this way, it is possible to determine whether there are any abnormalities such as errors or omissions in the parts of the automobile chassis 102 that need to be inspected.
[0040] Specifically, the camera assembly 30 captures photos of the car chassis 102, collects image feature information on the assembly status of relevant parts on the car chassis 102, and the vision processing module 300 compares the above image feature information with the preset image template stored in the controller 200. By judging the feature differences, the car chassis 102 automatically determines whether the assembly status of the parts is correct.
[0041] Among these features, image feature information includes key process information of components. Here, key points of the components refer to the tightening bolts of the battery pack, the coolant pipes, and the assembly status of the high-voltage wiring harness. Thus, when performing component and assembly judgments, the image feature information of key locations can be identified and judged to determine the effective assembly status of the vehicle chassis 102. Specifically, by comparing the three-dimensional feature information of the assembly status of assembled components identified from the image with the three-dimensional feature information of preset image templates stored in the controller 200, the controller automatically determines whether the current assembly status of the components is correct by judging the feature differences.
[0042] Furthermore, the vision processing module 300 can also be connected to the factory information system 400 to feed back results such as whether there are errors or omissions in the assembly of the car chassis 102 to the factory information system 400. Specifically, after the main line fixture drives the car chassis 102 into the workstation, it triggers the corresponding limit switch 40. After the limit switch 40 is triggered, the camera component 30 starts taking pictures. After the overall car chassis 102 picture is taken, the vision processing module 300 processes it to obtain a real-time assembly picture of the overall car chassis 102, and compares and verifies it with the preset image template of the controller 200, thereby determining whether there are any abnormalities such as errors or omissions in the assembly of the car chassis 102, and feeding back the results to the factory information system 400.
[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0044] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
