[0002] In the automotive industry, chassis inspection has traditionally relied on manual labor to check the tightness of chassis bolts and the proper connection of connectors. However, prolonged manual inspection can lead to visual fatigue, and errors can severely impact vehicle quality. To avoid this, existing technologies utilize visual inspection equipment for automotive parts. Specifically, during vehicle assembly, the installation quality of the chassis can be quickly assessed based on images captured by the visual inspection equipment, combined with appropriate inspection procedures. However, automotive OEMs require dedicated visual inspection stations, consuming space and time, and different production plants require different inspection equipment models, resulting in poor versatility.

[0026] Reference Figure 1 , Figure 5 and Figure 6 This utility model provides an automobile chassis inspection system, including a pit 600 and an automobile chassis inspection mechanism, wherein, with reference to Figure 2 The vehicle chassis inspection mechanism includes a first moving part 100, a second moving part 200, a third moving part 300, and a vision inspection unit 400. The first moving part 100 has moving portions 110 at both ends for sliding connection with the inner walls of the trench 600 on both sides. The first moving part 100 can reciprocate along a first direction X. The second moving part 200 is connected above the first moving part 100 and can reciprocate along the first direction X and along a second direction Z, following the first moving part 100. The third moving part 300 is connected to the second moving part 200 and can reciprocate along the second direction Z, and can also reciprocate relative to the second moving part 200 along a third direction Y. The vision inspection unit 400 is fixed to the third moving part 300. The first direction X, the second direction Z, and the third direction Y are mutually perpendicular, and the second direction Z is the depth direction of the trench 600.

[0027] Once the vehicle to be inspected is positioned above the pit 600, the first moving component 100, guided by its two moving parts 110 on the inner wall of the pit 600, moves at a constant speed from the front to the rear of the vehicle along its longitudinal direction (first direction X). Simultaneously, the second moving component 200 adjusts its position in the second direction Z in real time according to the chassis height, causing the third moving component 300 to rise and fall to the optimal shooting distance. The third moving component 300 then scans left and right along the transverse direction (third direction Y) of the vehicle on the second moving component 200, enabling the visual inspection unit 400 to align with components at different transverse positions on the chassis. Through coordinated control, the first moving component 100, the second moving component 200, and the third moving component 300 achieve area-by-area coverage inspection of the chassis.

[0028] Understandably, in actual use in the workshop, the pit 600 is used for the four-wheel alignment process of automobiles, and the space of the pit 600 is for inspection personnel to enter and perform secondary inspections of the automobile chassis during the four-wheel alignment. In the embodiment of this utility model, when the four-wheel alignment equipment is adjusting and inspecting the wheels, the automobile chassis inspection mechanism can be used simultaneously to inspect the automobile chassis. The two processes share the same vehicle position and the space of the pit 600, eliminating the need to wait for the four-wheel alignment to be completed before transferring the vehicle, forming a parallel workflow, improving the production cycle, and reducing the number of chassis inspection stations in the workshop, thus saving space.

[0029] In summary, the vehicle chassis inspection mechanism is integrated into the existing pit 600 in the workshop to form a complete vehicle chassis inspection system. While performing four-wheel alignment, it can also perform visual inspection of the entire vehicle chassis through the movement and cooperation of the first moving part 100 and the third moving part 300.

[0030] In some embodiments, refer to Figure 2 The first moving member 100 is provided with proximity sensors 500 at both ends in the first direction X, and the proximity sensors 500 are configured to control the first moving member 100 to stop moving.

[0031] In the actual testing process, when the first moving part 100 approaches the limit position of the trench 600 along the first direction X, the proximity sensors 500 installed at both ends of the first moving part 100 will monitor the distance to the obstacle in front in real time; once the distance is less than the safety threshold, the proximity sensor 500 immediately sends a trigger signal to the control system (not shown in the figure) and cuts off the power mechanism of the first moving part 100 (which can be a common drive device such as a drive motor), so that the first moving part 100 decelerates smoothly to a complete stop and avoids rigid collision.

[0032] In some embodiments, refer to Figure 2The first moving part 100 is fixedly connected to a lifting motor 120, and the driving end of the lifting motor 120 is fixedly connected to the side of the second moving part 200 facing the first moving part 100.

[0033] When height adjustment is required, the lifting motor 120 is activated, converting rotational motion into linear motion, which pushes the second moving part 200 to move up or down along the second direction Z, thereby adjusting the distance between the vision detection unit 400 and the car chassis to adapt to cars with different chassis heights.

[0034] In some embodiments, refer to Figure 2 and Figure 3 The third moving member 300 includes two first lateral moving members 310 and one second lateral moving member 320. The two first lateral moving members 310 are arranged sequentially along the second direction Z. The two first lateral moving members 310 can slide on the second moving member 200 along the third direction Y to move away from or towards each other. Each first lateral moving member 310 is fixed with a visual detection unit 400, which is located at the end of the first lateral moving member 310 that is far away from each other. The second lateral moving member 320 is arranged parallel to the first lateral moving members 310 along the first direction X on the second moving member 200. The second lateral moving member 320 can slide on the second moving member 200 along the third direction Y. The visual detection unit 400 is fixedly connected to the second lateral moving member 320. When the opposite ends of the two first lateral moving members 310 abut against each other, the distance between the two visual detection units 400 on the first lateral moving member 310 is L. The maximum moving distance of the visual detection unit 400 on the second lateral moving member 320 is S. L≤S.

[0035] After the detection begins, the two first lateral movement members 310 separate from their initial closed state to the sides, and the vision detection units 400 they carry move towards the outside of the wheel, aligning with the components on both sides of the chassis (such as longitudinal beams, suspension components, etc.); at the same time, the second lateral movement member 320 slides on the second moving member 200, carrying the vision detection unit 400 to scan back and forth in the central area of ​​the chassis, covering the components in the central area (such as drive shafts, exhaust pipes, etc.), where S is the maximum displacement of the second lateral movement member 320 sliding on the second moving member 200.

[0036] It should be emphasized that when detecting two narrower vehicle models, the first lateral movement component 310 only needs to separate within a small range; while for wider vehicle models, it can be fully extended until the distance between the two detection units reaches its maximum, effectively covering the wider vehicle models.

[0037] Furthermore, during the movement of the three relatively independent visual inspection units 400, since the stroke S of the visual inspection unit 400 on the second transverse member 320 is designed to be no less than the minimum distance L between the visual inspection units 400 on the two first transverse members 310, it can be ensured that the detection range of the middle visual inspection unit 400 can completely cover all areas between the two visual inspection units 400, thus avoiding detection blind spots.

[0038] Specifically, refer to Figure 3 Above the second moving member 200, two second guide rails 210 extending in the Y direction are provided. The first transverse moving member 310 is slidably connected to one of the second guide rails 210, and the second transverse moving member 320 is slidably connected to the other second guide rail 210. The two second guide rails 210 are laid parallel to each other on the top surface of the second moving member 200, forming a side-by-side layout. The two first transverse moving members 310 share one second guide rail 210, allowing them to move closer or further apart. The second transverse moving member 320 uses the other second guide rail 210 independently, and its sliding is not affected by the first transverse moving member 310.

[0039] As a further optimization of the above embodiments, refer to Figure 3 In the same first lateral movement member 310, the end of the first lateral movement member 310 away from the visual inspection unit 400 is slidably connected to the second moving member 200. The first lateral movement member 310 moves along the third direction Y, allowing the visual inspection unit 400 to move beyond the end of the second moving member 200. A cantilever structure is formed between the first lateral movement member 310 and the second moving member 200, which can maximize the extension of the visual inspection unit 400. Specifically, when it is necessary to inspect a component whose chassis edge exceeds the width of the second moving member 200, the first lateral movement member 310 continues to slide outward, allowing the visual inspection unit 400 to completely extend beyond the end face of the second moving member 200 until the visual inspection unit 400 reaches the position where it needs to be photographed and inspected.

[0040] In some embodiments, refer to Figure 1 and Figure 2 The vehicle chassis inspection system also includes a first guide rail 610 extending along the first direction X, grooves 620 provided on the inner walls of both sides of the trench 600, the first guide rail 610 fixed in the grooves 620, a first slider 611 slidably connected to the first guide rail 610, and a moving part 110 fixedly connected to the first slider 611.

[0041] During installation, the first guide rail 610 is first embedded into the pre-made groove 620 on the inner wall of the trench 600. When the first slider 611 slides on the first guide rail 610, it will move the first moving part 100. The two first guide rails 610 support the car chassis detection mechanism to ensure the stability of the entire car chassis detection system.

[0042] In some embodiments, refer to Figure 5 and Figure 6 The second moving member 200 can reciprocate along the second direction Z so that the second moving member 200 and the third moving member 300 can be built into the trench 600, or the third moving member 300 can protrude from the surface of the trench 600; when the third moving member 300 protrudes from the surface of the trench 600, the third moving member 300 can move along the third direction Y so that the vision detection unit 400 moves to both ends of the second moving member 200 in the third direction Y and is located above the surface of the trench 600.

[0043] Reference Figure 5 In the non-operating state, the lifting motor 120 drives the second moving part 200 to descend to the lowest point. At this time, the second moving part 200 and the third moving part 300 are completely retracted into the space of the trench 600, with their tops not exceeding the opening plane of the trench 600, thus not affecting the normal passage of people and vehicles in the surrounding area; refer to Figure 6 When the inspection task is started and the vehicle chassis inspection mechanism is in working condition, the second moving part 200 is raised to the height required for operation, and the third moving part 300 and its vision inspection unit 400 protrude from the surface of the pit 600 and enter between the vehicle chassis and the ground. At this time, the third moving part 300 moves along the third direction Y, and the width range of the vehicle chassis is covered by the movement trajectory of the vision inspection unit 400, and the vehicle chassis is visually inspected.

[0044] As a further optimization of the above embodiments, refer to Figure 1 Along the first direction X, a shielding area 630 is provided at one end of the trench 600. When the second moving member 200 and the third moving member 300 are both built into the trench 600, the first moving member 100 can move along the first direction X so that the first moving member 100, the second moving member 200 and the third moving member 300 are all built into the shielding area 630.

[0045] After all the inspection tasks are completed, the second moving part 200 first descends until it is completely inside the trench 600, so that the third moving part 300 and the vision inspection unit 400 both enter the trench 600. Then, the first moving part 100 moves along the first direction X towards one end of the trench 600 until the entire vehicle chassis inspection mechanism is completely embedded in the shielding area 630. It should be emphasized that the shielding area 630 can be constructed by covering one end of the surface of the trench 600 with a baffle. In this working state, whether the staff walking on the opening plane of the trench 600 or the staff entering the trench 600, they will not be affected.

[0046] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0047] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0048] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
