[0034] As Figures 1 to 3 The utility model provides a vehicle contour detection device, including the limit frame 1, and the limit frame 1 is the door type structure of approximate "∏", can adopt gantry, or is the door type frame of arbitrary production site, does not make limit and requirement.

[0035] Still include the main body of the board 2, and the main body of the board 2 is the plate structure, and the outside part is assembled with the limit frame 1, and the middle is provided with the hollow region, and the form of the hollow region is same with the outer contour shape and size of the vehicle to be measured, and extends to the bottom of the main body of the board 2, and the vehicle to be measured passes.

[0036] The vehicle to be measured stops on the track 4 at the station, can walk along the track 4, and the limit frame 1 and the main body of the board 2 (the hollow region part thereof) are straddled on the track 4, after the vehicle to be measured passes through from the hollow region of the main body of the board 2 along the track 4, whether the scratch and the scratch on the vehicle body, if there is, represent that the part does not meet the standard requirement, needs to be reformed.

[0037] Preferably, according to the detection requirement, a plurality of coordinate points 3 are arranged on the inside surface of the main body of the board 2 (the hollow region side, the side towards the vehicle body), further, the distribution of the coordinate points 3 on the main body of the board 2 is as shown in Figure 5 The coordinate points 3 are virtual points, and only the positions that need to be detected in the process of determining whether the main body of the board 2 meets the standard, and do not need to be marked on the actual product of the main body of the board.

[0038] Further, the coordinate points 3 are virtual points for determining whether the main body of the board 2 meets the standard, which are important for appearance detection, and pressure sensors can be arranged on the main body of the board 3 at positions corresponding to the coordinate points 3, and the pressure sensors are electrically connected or signal-connected with a controller, when the detection data of the pressure sensor 3 is within the standard range of the pressure value generated by the normal passing of the vehicle, it represents that the vehicle contour meets the standard requirement, and when it exceeds the standard range (less than or greater than), it represents that the point position does not meet the standard requirement, and an alarm is prompted.

[0039] The contours of different vehicle models can be different, therefore, each vehicle model has its exclusive main body of the board 2, in order to facilitate the detection of the contours of different vehicle models, the main body of the board 2 is detachably connected with the limit frame 1, and a mounting seat is arranged on the limit frame 1, and the main body of the board 2 is bolted with the mounting seat.

[0040] Further, the main hanging plate 2 is reversibly connected with the limiting frame 1 through the adjustable hinge 11. Figure 1 and Figure 3 、 Figure 4 As shown, the adjustable hinge 11 includes a first end 111 connected with the limiting frame 1 and a second end 112 fixed with the main hanging plate 2, the first end 111 and the second end 112 are reversibly connected, in the embodiment, the first end 111 and the second end 112 are assembled and connected through the rotating shaft 113, the first end 111 and / or the second end can rotate around the rotating shaft 113, so that the first end 111 and the second end 112 overlap, reducing the volume when placed, and the limiting structure is provided on the rotating shaft 113, so that the first end 111 and the second end 112 will not be actively reset after being unfolded or overlapped; at least one strip-shaped fixed slot 1111 is provided on the first end 111, the first end 111 is fixed with the limiting frame 1 through the fixed slot 1111, and the position of the first end 111 on the limiting frame 1 is adjusted through the relative position of the fixed slot 1111; the second end 112 is provided with a fixed sliding groove 1121, and the main hanging plate 2 is fixed with the adjustable hinge 11 through the fixed sliding groove 1121, and the fixed position of the main hanging plate 2 and the second end 112 is adjusted.

[0041] In the embodiment, the main hanging plate 2 is symmetrically divided into multiple hanging plates 21, and the adjacent hanging plates 21 are assembled and connected with each other, preferably, the adjacent hanging plates 21 are reversibly connected through hinges, which is convenient for arrangement and storage. In the embodiment, the main hanging plate 2 is longitudinally cut into two parts symmetrically left and right at the center line, and each part is cut into upper, middle and lower parts, that is, the whole main hanging plate 2 is divided into six hanging plates 21, and each hanging plate 21 is connected through a hinge.

[0042] When contour detection is not needed, the left and right hanging plates 21 are separated, and then each adjustable hinge 11 is rotated in the buckling direction until the first end 111 and the second end 112 are buckled together, or until the first end 111 and the second end 112 are perpendicular to each other, so that the vehicle can smoothly pass through the limiting frame 1, and the main hanging plate 2 does not affect the vehicle. When the main hanging plate 2 needs to be replaced, the bolts on the second end 112 and the main hanging plate 2 are sequentially removed from top to bottom, and after the main hanging plate 2 is taken down as a whole, each hanging plate is folded and stored in a predetermined order.

[0043] The main hanging plate 2 can be made of carbon steel, which is firm and durable, and can reduce the deformation caused by scratching or long-term storage and gravity, which may cause errors in detection. In order to avoid irreversible damage to the vehicle to be measured, especially the vehicle to be measured with unqualified contour, preferably, a measuring plate 23 is provided on the inner side (the side facing the vehicle body) of the main hanging plate 2, the measuring plate 23 is made of a material with certain elasticity, deformation force and irreversible scratch on the contour of the vehicle to be measured, such as nylon material, silica gel material, etc.

[0044] Preferably, the measuring plate 23 is a strip with the same thickness as or slightly greater than the thickness of the main mounting plate 2, and is bonded or attached to the measuring surface of the main mounting plate 2 by any other means.

[0045] Furthermore, the nylon or silicone measuring plate 23 itself is bendable. Therefore, the measuring plate 23 corresponding to the two left and right mounting plates 21 (three sections) can be a single, complete piece without cutting, i.e., there are two measuring plates 23. When the measuring plate 23 is made of other materials that will not cause irreversible damage to the vehicle under test, if the material is not bendable, but the adjacent mounting plates 21 are connected by hinges, resulting in a certain gap between the adjacent mounting plates 21, then the measuring plate 23 and the main mounting plate 2 are cut at the same position, but the edge of the cut measuring plate 23 extends beyond the edge of the corresponding mounting plate 21. After unfolding, the adjacent measuring plates 23 (after cutting) contact each other, avoiding the creation of detection gaps. The measuring plate 23 can be connected to the main mounting plate 2 by any method such as plugging or bonding, without requirements or restrictions, as long as it does not fall off during the testing process.

[0046] The measuring surface of the measuring plate 23 corresponds to the outline shape and size of the vehicle to be measured. After the vehicle passes through the space enclosed by the measuring plate 23, the vehicle body is checked for scratches to determine if the outline is acceptable. Preferably, multiple pressure sensors are arranged on the measuring surface, and the positions of the pressure sensors can be as follows: Figure 5 Corresponding to coordinate point 3, a total of 16 pressure sensors are installed on the single-sided main mounting plate 2 (including the bottom mounting plate mentioned later). Correspondingly, 16 virtual coordinate points 3 are set on the main mounting plate to determine whether the main mounting plate meets the standard requirements. As mentioned above, the pressure value detected by the pressure sensor is compared with the standard range to further determine whether the vehicle body contour meets the standard. This is especially applicable when the actual contour size is smaller than the standard size, in order to detect whether the vehicle under test and the measuring plate 23 have effective pressure contact. Preferably, the coordinate points 3 and the corresponding pressure sensors are positioned to avoid the gaps between adjacent mounting plates.

[0047] As mentioned above, the vehicle contour detection device can detect the contours of the side and top of the vehicle. In practical applications, when it is also necessary to detect the contours of the bottom of the vehicle body, bottom mounting plates 22 for bottom contour detection can be set on the outer and inner sides of the track 4 respectively. The bottom mounting plate 22 on the outer side of the track 4 can be integrally formed with the main mounting plate 2, and the bottom mounting plate 22 on the inner side of the track 4 is set in the track 4 through a bracket.

[0048] In summary, the vehicle contour detection device provided by this utility model has the following technical advantages compared with the prior art:

[0049] 1. The use of simplicity: before using, only need to unfold the device, push the vehicle through the device, check whether the vehicle is scratched with the device, or observe the scratch position, quickly find out the place where the vehicle outer contour does not meet the requirements. Realize fast detection, quickly find out the problem, reduce the error caused by personnel detection and measurement;

[0050] 2. The device body uses carbon steel material, which is firm and durable, reduces the deformation caused by scratching or long-term storage and gravity, and causes detection error;

[0051] 3. The inside of the device body uses nylon material, which can avoid irreversible scratches left after the vehicle and the contour detection device are scratched;

[0052] 4. The limit frame is provided, which can be installed with the main hanging plate suitable for different vehicles. When measuring different vehicles, only the limit hanging plate of the vehicle type needs to be installed to measure the vehicle contour. Reduce the manufacturing cost and use cost.

[0053] As described above, in combination with the given scheme content, similar technical solutions can be derived. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application, which does not deviate from the content of the present application, still belongs to the scope of the present application.
