Description

Technical Field

[0001] This application relates to the field of vehicle body inspection technology, and in particular to positioning mechanisms and door inspection devices. Background Technology

[0002] During vehicle assembly, after the doors are installed on the body-in-white, inconsistent installation angles at the upper and lower hinges can affect the normal use of the door glass and pose potential risks such as water leakage. Therefore, after the doors are installed, the installation angles at the upper and lower hinges need to be checked. Currently, the hinge installation angle is indirectly obtained by measuring the distance H between the outer door panel at the upper and lower hinges and the outer side panel. In related technologies, measuring the distance H requires the vehicle to be taken off the assembly line and placed in a coordinate measuring machine (CMM) room for measurement. However, this measurement method requires the vehicle to be taken off the assembly line first, which is cumbersome, and the CMM method has low measurement efficiency, resulting in long processing times for batch testing. Utility Model Content

[0003] Therefore, it is necessary to provide a positioning mechanism and a door detection device that can realize online detection of the distance H without removing the vehicle from the production line, making the operation simpler and the detection efficiency higher.

[0004] A positioning mechanism, the positioning mechanism comprising:

[0005] A positioning component, wherein a support surface is constructed at one end along a first direction, the support surface is used to abut against the end of the outer side panel away from the inner side panel, and a measuring surface is constructed at the end of the positioning component away from the support surface along the first direction.

[0006] The positioning element is also provided with a positioning surface, which is perpendicular to the second direction. The positioning surface is used to abut against the end of the outer door panel that is close to its own hinge along the second direction.

[0007] The positioning member also has a positioning part, which is used to cooperate with the hinge to limit the position of the positioning member in a third direction;

[0008] Wherein, any two of the first direction, the second direction, and the third direction are perpendicular, and the first direction is the length / width / height direction of the positioning element. In the detection state, the positioning element is configured such that the third direction is parallel to the vehicle height direction.

[0009] In some embodiments, the positioning element includes a positioning body, and a support platform is provided on one end of the positioning body along the first direction. The end face of the support platform opposite to the positioning body is the support surface.

[0010] In some embodiments, the positioning element includes a plurality of support platforms, and the plurality of support platforms are disposed at the edges of the positioning body.

[0011] In some embodiments, the positioning element includes a measuring platform, which protrudes from one end of the positioning body away from the support platform along the first direction, and the end face of the measuring platform away from the positioning body is the measuring surface.

[0012] In some embodiments, the end face of the measuring platform along the second direction is the positioning surface.

[0013] In some embodiments, the measuring stage includes a first extension and a second extension; the first extension is connected to one end of the positioning body away from the support platform along the first direction and extends along the first direction; the second extension is connected to one end of the first extension away from the positioning body and extends along the second direction, and both the positioning surface and the measuring surface are formed on the second extension.

[0014] In some embodiments, the support platform, the measuring platform, and the positioning body are integrated into one unit.

[0015] In some embodiments, the positioning part is a positioning slot disposed at one end of the positioning member along the first direction, and the positioning slot is used to engage with the hinge.

[0016] In some embodiments, the positioning member is provided with a plurality of weight-reducing grooves.

[0017] A vehicle door detection device includes the aforementioned positioning component and a measuring component, the measuring component being used to detect the distance between the end of the outer door panel facing away from the inner door panel and the measuring surface.

[0018] The aforementioned positioning mechanism and door inspection device, during the inspection process, can restrict the position of the positioning component along a third direction by cooperating with the hinge on the door, thereby confining the positioning component in the vehicle height direction to the area where the hinge is located. The support surface on the positioning component can abut against the end of the outer side panel away from the inner side panel. Simultaneously, by moving the positioning component along a second direction, its positioning surface abuts against the end of the outer door panel along the second direction near its own hinge. At this time, the distance between the measuring surface and the end of the outer door panel away from the inner door panel is relatively short. It is only necessary to measure the distance between the measuring surface and the end of the outer door panel away from the inner door panel, and add the distance between the measuring surface and the support surface to obtain the distance H between the outer door panel and the outer side panel at the hinge. In the above inspection process, it is only necessary to place the positioning component in an appropriate position and measure the distance after positioning. There is no need to remove the vehicle from the production line and enter the coordinate measuring machine room for measurement, which means that online vehicle inspection can be achieved. Therefore, the operation is simpler and the inspection efficiency is higher. Attached Figure Description

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, 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 possible implementation.

[0039] See Figures 1 to 3 First, let's briefly introduce the structure of the door mounting area. The body-in-white includes an outer side panel 410 and an inner side panel 420. The outer side panel 410 is connected to the inner side panel 420 on the side closest to the external environment. Taking the left door as an example, the outer side panel 410 on the left side of the body-in-white is connected to the left side of the inner side panel 420. The door includes an outer door panel 430 and an inner door panel 440. The inner door panel 440 is hinged to the outer side panel 410 via two hinges 450. The outer door panel 430 is connected to the inner door panel 440 on the side facing away from the outer side panel 410 (i.e., the side closest to the external environment). Taking the left door as an example, the outer door panel 430 on the left side is connected to the left side of the inner door panel 440. The hinge 450 includes a fixed part 451 and a hinged part 452 connected together, which are roughly L-shaped. The fixing part 451 is fixed to the outer side panel 410, and the hinge part 452 is hinged to the inner door panel 440. The door can be rotated through the hinge 450 to realize the opening and closing of the door.

[0040] One embodiment of this application provides a positioning mechanism for detecting the distance H between the outer door panel 430, which is away from the inner door panel 440, and the side panel 410 at the upper and lower hinges.

[0041] See Figures 4 to 5An embodiment of this application provides a positioning mechanism including a positioning member 10. A support surface 210 is formed at one end of the positioning member 10 along a first direction, and a measuring surface 321 is formed at the other end of the positioning member 10 along the first direction away from the support surface 210. A positioning surface 322 is also formed on the positioning member 10, and the positioning surface 322 is perpendicular to a second direction. The positioning member 10 also has a positioning part 110. See also... Figure 3 ,as well as Figures 6 to 9 The supporting surface 210 abuts against one end of the outer side panel 410 away from the inner side panel 420; the positioning surface 322 abuts against one end of the outer door panel 430 along the second direction near its own hinge 450; the positioning part 110 cooperates with the hinge 450 to limit the position of the positioning member 10 along the third direction. Wherein, any two of the first direction, the second direction, and the third direction are perpendicular, and the first direction is the length / width / height direction of the positioning member 10. In the detection state, the positioning member 10 is configured such that the third direction is parallel to the vehicle height direction.

[0042] During the detection process, the positioning mechanism and door detection device described above can restrict the position of the positioning member 10 along a third direction by cooperating with the hinge 450 on the door through the positioning part 110, thereby limiting the positioning member 10 in the vehicle height direction to the area where the hinge 450 is located. The support surface 210 on the positioning member 10 can abut against the end of the side outer panel 410 away from the side inner panel 420. At the same time, the positioning member 10 is moved along the second direction so that its positioning surface 322 abuts against the end of the door outer panel 430 along the second direction close to its own hinge 450. At this time, the distance between the measuring surface 321 and the end of the door outer panel 430 away from the door inner panel 440 is relatively close, and it is only necessary to measure the distance 'a' between the measuring surface 321 and the end of the door outer panel 430 away from the door inner panel 440 (see reference). Figure 8 and Figure 9 Adding the distance between the measuring surface 321 and the supporting surface 210, the distance H between the outer door panel 430 and the side panel 410 at the hinge 450 can be obtained. In the above inspection process, it is only necessary to place the positioning component 10 in the appropriate position and then measure the distance after positioning. There is no need to remove the vehicle from the production line and enter the coordinate measuring room for measurement, which means that online vehicle inspection can be achieved. Therefore, the operation is simpler and the inspection efficiency is higher.

[0043] Specifically, from the perspective of the attached diagram, the first direction is the left-right direction, the second direction is the front-back direction, and the third direction is the up-down direction. The hinge 450 connected to the door is located on the front side of the door.

[0044] Taking the left-side door shown in the attached figure as an example, when using the positioning mechanism in this embodiment for testing, the positioning member 10 needs to be placed on the front side of the door. The positioning part 110 and the hinge 450 cooperate to limit the height of the positioning member 10 to the position of the hinge 450. Simultaneously, the support surface 210 abuts against the left end of the side panel 410, and the positioning member 10 is moved backward until the positioning surface 322 abuts against the front end of the door panel 430. Then, the distance 'a' between the measuring surface 321 and the left end of the door panel 430 is measured.

[0045] See Figures 3 to 6 In some embodiments, the positioning element 10 includes a positioning body 100, and a support platform 200 is protruding from one end of the positioning body 100 along a first direction. The end face of the support platform 200 away from the positioning body 100 is a support surface 210.

[0046] In other embodiments, the support platform 200 may be omitted, and the end face of the positioning body 100 may be used directly as the support surface 210.

[0047] See Figures 4 to 6 In some embodiments, the positioning element 10 includes a plurality of support platforms 200, which are distributed at the edges of the positioning body 100. This arrangement maximizes the spacing between the support platforms 200, making them more dispersed and increasing the stability of the contact, thus reducing the likelihood of shaking and improving detection accuracy.

[0048] Specifically, in the embodiment shown in the attached drawings, the positioning body 100 is generally rectangular, and there are four support platforms 200, which are located at the four corners of the positioning body 100.

[0049] See Figures 4 to 6 In some embodiments, the positioning member 10 includes a measuring platform 300, which protrudes from the end of the positioning body 100 away from the support platform 200 along a first direction. The end face of the measuring platform 300 away from the positioning body 100 is the measuring surface 321.

[0050] Compared to directly using the end face of the positioning body 100 as the measuring surface 321, in the above embodiment, by constructing the measuring surface 321 by protruding the measuring platform 300 on the positioning body 100, the materials required for manufacturing can be reduced, costs can be lowered, and weight can be reduced.

[0051] See Figures 4 to 6 In some embodiments, the end face of the measuring stage 300 along the second direction is the positioning surface 322.

[0052] Specifically, the positioning surface 322 is the surface adjacent to the measuring surface 321, and the two are perpendicular to each other. In other embodiments, the rear end surface of the positioning body 100 can also be used as the positioning surface 322.

[0053] See Figures 4 to 6 In some embodiments, the measuring stage 300 includes a first extension 310 and a second extension 320; the first extension 310 is connected to one end of the positioning body 100 away from the support stage 200 along a first direction and extends along the first direction; the second extension 320 is connected to one end of the first extension 310 away from the positioning body 100 and extends along a second direction, and both the positioning surface 322 and the measuring surface 321 are formed on the second extension 320.

[0054] Specifically, the first extension 310 and the second extension 320 are generally L-shaped, and the outer corners at their connection are chamfered to prevent sharp edges from scratching operators. Setting the measuring stage 300 in this L-shape minimizes the material required for manufacturing, reducing costs and weight. In other embodiments, the measuring stage 300 can also be rectangular.

[0055] See Figures 4 to 6 In some embodiments, the support platform 200, the measuring platform 300, and the positioning body 100 are integrated into one unit.

[0056] Specifically, the positioning component 10 is made of aluminum alloy to reduce weight. The support platform 200, measuring platform 300, and positioning body 100 can be integrally formed into a single unit through processes such as casting, forging, or stamping, thus eliminating the need for assembly.

[0057] See Figures 3 to 5 ,as well as Figure 7 In some embodiments, the positioning part 110 is a positioning slot provided at one end of the positioning member 10 along the first direction, and the positioning slot is used to be engaged on the hinge 450.

[0058] Specifically, the positioning groove is formed by recessing the end face of the positioning body 100 near the support platform 200. The positioning groove is used to engage with the fixing part 451 of the hinge 450 to limit the height of the positioning member 10 to the position of the hinge 450. Preferably, the dimensions of the positioning groove in the third direction are adapted to the fixing part 451 so that after the fixing part 451 is engaged with the positioning groove, the positioning member 10 is less likely to wobble, and the detection results are more accurate.

[0059] See Figures 4 to 5 In some embodiments, the positioning member 10 is provided with a plurality of weight-reducing grooves 120 to reduce the weight of the positioning member 10 and reduce manufacturing costs.

[0060] See Figure 3 and Figure 9 The door detection device provided in one embodiment of this application includes the positioning member 10 in any of the above embodiments, and also includes a measuring member. The measuring member is used to detect the distance a between the end of the outer door panel 430 away from the inner door panel 440 and the measuring surface 321.

[0061] Specifically, the measuring component can be a vernier caliper or a measuring tape, etc.

[0062] 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.

[0063] 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 protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
