[0031] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0032] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0033] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0034] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0035] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0036] It should be noted that if an element is referred to as being "fixed to" or "provided on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0037] As described in the background art, the detection tooling is large in size and heavy in weight, so that one person cannot complete the installation of the detection tooling, and two people are required to cooperate in the installation. At the same time, the installation takes a long time.

[0038] In addition, the inspection tool simulates standard instrument panel and door panel parts, and can measure the impact of the body-in-white on the clearance and surface difference of the assembled instrument panel and door panel. However, the measurement results cannot give an intuitive indication of how the body should be adjusted. The body needs to be continuously tested, adjusted, and measured to obtain the adjustment data, which results in a longer analysis cycle for body problems and reduces efficiency.

[0039] In view of at least one of the above problems, an embodiment of the present application provides a vehicle inspection tool. When in use, the positioning assembly is assembled on the first component of the vehicle, the measuring surface on the measuring piece can assist in measuring the deviation of the second component of the vehicle, and the marking piece can pass through the measuring hole to mark the second component, thereby assisting in measuring the deviation of the positioning hole on the second component. In this way, the components on the vehicle can be directly measured without setting up a simulation module. On the one hand, the structural complexity of the inspection tool can be reduced, thereby reducing the total weight and manufacturing cost of the inspection tool, and thus facilitating inspection by inspection personnel; on the other hand, directly measuring the components on the vehicle can intuitively and accurately feedback the dimensional deviation value of the specific position of the vehicle body, saving time for problem analysis and helping to improve inspection efficiency.

[0040] Specifically, referring to FIGS. 1 , 2 , 3 and 4 , an embodiment of the present application provides a vehicle inspection tool 100 , which includes a first inspection fixture 10 , and the first inspection fixture 10 includes a positioning assembly 11 , a measuring member 12 and a marking member 13 .

[0041] The positioning assembly 11 is used to be assembled on a first component of a vehicle. For example, the first component may be a door guard plate. The measuring member 12 is connected to the positioning assembly 11, and is provided with a measuring surface 12a and a measuring hole 12b. The measuring surface 12a is used to assist in measuring the deviation of a second component of the vehicle; for example, the second component may be a vehicle body frame 300. Here, the deviation of the second component may be the deviation value between the positioning surface on the second component and the measuring surface 12a. The marking member 13 is used to penetrate the measuring hole 12b and mark the second component, and the mark can be used to assist in measuring the deviation value of the positioning hole on the second component.

[0042] In one example, after assembling the vehicle inspection tool 100 with the components on the vehicle, a measuring ruler is used to measure the deviation between the positioning surface of the instrument panel on the vehicle body frame 300 and the measuring surface 12a, and the deviation between the measuring mark and the positioning hole of the instrument panel on the vehicle body frame 300. The inspector can directly adjust the instrument panel and the positioning surface on the vehicle body frame 300 according to the above deviation values, thereby saving analysis time and improving the efficiency of inspection and adjustment.

[0043] In addition, compared with the related art, the vehicle inspection tool 100 provided in the embodiment of the present application can directly measure the components on the vehicle without setting up a simulation module. On the one hand, it can reduce the structural complexity of the inspection tool, thereby reducing the total weight and manufacturing cost of the inspection tool, which is conducive to installation and inspection by a single person, reducing the installation difficulty and inspection difficulty of the vehicle inspection tool 100.

[0044] In one embodiment, the positioning assembly 11 includes a main board body 111, a first positioning member 112, a second positioning member 113 and a third positioning member 114, and the first positioning member 112, the second positioning member 113 and the third positioning member 114 are arranged at intervals on a side of the main board body 111 close to the first component; the first positioning member 112 is provided with a first fitting surface 1121 on a side away from the main board body 111, the second positioning member 113 is provided with a second fitting surface 1131 on a side away from the main board body 111, and the third positioning member 114 is provided with a third fitting surface 1141 on a side away from the main board body 111.

[0045] The positioning assembly 11 can be stably assembled on the door guard plate of the vehicle by providing the first positioning member 112, the second positioning member 113 and the third positioning member 114. The first fitting surface 1121, the second fitting surface 1131 and the third fitting surface 1141 can be fitted to the surface of the door guard plate when the positioning assembly 11 is assembled, thereby achieving the positioning of the positioning assembly 11.

[0046] It can be understood that the first fitting surface 1121 , the second fitting surface 1131 , and the third fitting surface 1141 match the shape of the fitting area on the first component of the vehicle.

[0047] In one embodiment, a first positioning pin 1122 is disposed on the first fitting surface 1121 , and a second positioning pin 1132 is disposed on the second fitting surface 1131 ; the first positioning pin 1122 and the second positioning pin 1132 are used to pass through the assembly hole on the first component.

[0048] It is understandable that the first locating pin 1122 and the second locating pin 1132 are disposed at the same position as the assembly hole on the first component, and the diameters of the first locating pin 1122 and the second locating pin 1132 are the same as the diameter of the assembly hole on the first component.

[0049] It should be noted that the cross-sectional area of ​​the first positioning pin 1122 is smaller than the area of ​​the first bonding surface 1121, so that after the first positioning pin 1122 is set on a part of the surface of the first bonding surface 1121, the other part of the surface of the first bonding surface 1121 can also be bonded to the surface of the first component. The cross-sectional area of ​​the second positioning pin 1132 is smaller than the area of ​​the second bonding surface 1131, so that after the second positioning pin 1132 is set on a part of the surface of the second bonding surface 1131, the other part of the surface of the second bonding surface 1131 can also be bonded to the surface of the first component.

[0050] By providing two positioning pins and three fitting surfaces, the positioning assembly 11 can be accurately assembled on the first component of the vehicle.

[0051] In one embodiment, the center lines of the first positioning member 112, the second positioning member 113, and the third positioning member 114 form a triangle. It can be understood that three points can determine a plane, and the triangle has good stability. By making the center lines of the first positioning member 112, the second positioning member 113, and the third positioning member 114 form a triangle, the above principle can be used to facilitate the inspection personnel to quickly and accurately assemble the positioning assembly 11 on the first component of the vehicle.

[0052] In one embodiment, a weight-reducing hole 1111 is provided on the main board body 111. By providing the weight-reducing hole 1111, the weight of the main board body 111 can be reduced, which is conducive to making the vehicle inspection tool 100 lighter and reducing the installation difficulty of the inspection personnel.

[0053] It can be understood that the number of the weight-reducing holes 1111 can be one or more, and the weight-reducing holes 1111 can be circular holes, elliptical holes, rectangular holes, etc.

[0054] In one embodiment, the measuring surface 12a is disposed on the side wall of the measuring member 12. By disposing the measuring surface 12a on the side wall of the measuring member 12, the difficulty of measurement can be reduced.

[0055] It can be understood that the number of the measuring surfaces 12a can be one or more.

[0056] In a specific embodiment, a measuring surface 12a is provided on both the top side wall and the bottom side wall of the measuring member 12. The measuring surface 12a located on the top side wall of the measuring member 12 can assist in measuring the deviation value of the upper positioning surface of the instrument panel on the vehicle body frame 300, and the measuring surface 12a located on the bottom side wall of the measuring member 12 can assist in measuring the deviation value of the lower positioning surface of the instrument panel on the vehicle body frame 300.

[0057] In one embodiment, the measuring member 12 is detachably connected to the positioning assembly 11. In this way, the manufacturing difficulty of the vehicle inspection tool 100 can be reduced.

[0058] It should be noted that the measuring member 12 and the positioning assembly 11 can be detachably connected by bonding, clamping or bolting.

[0059] It is understandable that the measuring member 12 and the positioning assembly 11 may also be an integrated structure.

[0060] In one embodiment, the first gauge 10 further includes a first fastener 14 and a positioning mechanism 15, wherein the first fastener 14 connects the measuring piece 12 and the positioning assembly 11, and the positioning mechanism 15 is disposed between the measuring piece 12 and the positioning assembly 11 to position the measuring piece 12 and the positioning assembly 11. Thus, when assembling the measuring piece 12 and the positioning assembly 11, the measuring piece 12 and the positioning assembly 11 are first positioned by the positioning mechanism 15, and then the measuring piece 12 and the positioning assembly 11 are fixed by the first fastener 14. By providing the positioning mechanism 15, the difficulty of assembling the measuring piece 12 and the positioning assembly 11 can be reduced.

[0061] In one embodiment, the positioning mechanism 15 includes a limiting shaft (not shown) and a limiting hole (not shown), one of the limiting shaft and the limiting hole is arranged on the measuring member 12, and the other of the limiting shaft and the limiting hole is arranged on the positioning assembly 11.

[0062] In one embodiment, the positioning assembly 11 further includes a connecting plate 115, and the connecting plate 115 is connected to the main body 111. The measuring member 12 includes a main body 121 and a connecting portion 122 connected to the main body 121. The connecting plate 115 is connected to the connecting portion 122.

[0063] Further, the measuring surface 12a and the measuring hole 12b are provided on the main body 121. The shape of the main body 121 matches the contour shape of the to-be-detected area of ​​the second component of the vehicle.

[0064] In one embodiment, a bushing 16 is provided on the hole wall of the measuring hole 12b. It is understandable that the processing accuracy of the bushing 16 is relatively high. By providing the bushing 16, the marking accuracy of the marking member 13 can be improved.

[0065] In one embodiment, a locking hole 12c is provided on the hole wall of the measuring hole 12b, and the first gauge 10 further includes a second fastener 17, which is passed through the locking hole 12c and abuts against the bushing 16. It can be understood that the locking hole 12c is a threaded hole.

[0066] By providing the locking hole 12 c and the second fastener 17 , the bushing 16 can be fixed, thereby improving the assembly stability of the bushing 16 .

[0067] In one embodiment, the marking member 13 is a marking pen or a marking stamp. When the marking member 13 is a marking pen, a marking line (e.g., a circle) can be drawn on the second component using the marking pen when measuring the error. Further, a vernier caliper is used to measure the edge distance between the circle and the instrument panel positioning hole on the vehicle body frame 300, and the deviation value of the instrument panel positioning hole on the vehicle body frame 300 can be obtained by comparing the distance with the design theoretical distance.

[0068] When the marking member 13 is a marking stamp, the marking stamp can be used to stamp the second component when measuring the error. Further, the distance between the stamp mark and the edge of the positioning hole of the instrument panel on the vehicle body frame 300 is measured with a vernier caliper, and compared with the designed theoretical distance, the deviation value of the positioning hole of the instrument panel on the vehicle body frame 300 can be obtained.

[0069] It is understandable that the marking pen and the marking stamp can be marked with water-based paint. In this way, after the measurement is completed, alcohol can be used to wipe off the trace of the water-based paint on the vehicle frame 300, and the measurement is achieved without damaging the paint surface.

[0070] In one embodiment, the vehicle inspection tool 100 further includes a second inspection fixture 20, and the structure of the second inspection fixture 20 is symmetrical to the structure of the first inspection fixture 10. Thus, a set of vehicle inspection tool 100 includes two inspection fixtures, wherein the first inspection fixture 10 can assist in detecting the assembly deviation between the left door guard plate and the instrument panel of the vehicle, and the second inspection fixture 20 can assist in detecting the assembly deviation between the right door guard plate and the instrument panel of the vehicle.

[0071] It is understandable that the vehicle inspection tool 100 provided in the embodiment of the present application can not only measure the assembly size deviation between the door guard plate and the instrument panel, but also can detect the assembly size deviation between the A-pillar interior panel, the threshold interior panel and the door guard plate. It is only necessary to ensure that the shape contour of the measuring piece 12 matches the measured area of ​​the measured component.

[0072] The vehicle inspection tool 100 provided in the present application has at least the following beneficial effects: on the one hand, the tool is small in size and light in weight (a single inspection tool is only 450 mm long and weighs only 2.5 kg), and can be measured by one person. A single measurement takes only one minute, and the measurement time for a single vehicle takes only two minutes, which reduces the number of measurement personnel and measurement time, and can meet the needs of large-scale measurement; on the other hand, the inspection tool measurement result can directly reflect the specific deviation value of the assembly area (such as the instrument panel positioning hole and positioning surface) on the body frame 300 relative to the door guard plate positioning, which is convenient for corresponding adjustment of the body frame 300 according to the specific deviation value, so that the rectification period of the size deviation problem of the body frame 300 is short.

[0073] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0074] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
