Description

Technical Field

[0001] The present application relates to the technical field of automobile parts detection, and in particular to a tailgate and side panel clearance detection aid. Background Art

[0002] With the continuous development of the automobile industry, the development of new models has exploded. In order to achieve lightweight and styling needs, more and more models will install decorative panels on the tailgate to match the side panels. Therefore, when assembling the tailgate of the white body, it is necessary not only to ensure that the gap between the tailgate and the rear of the body meets the requirements of vehicle development, but also to consider whether the gap between the tailgate trim installed on the tailgate and the white body side panels meets the development requirements.

[0003] Due to the inherent individual tolerances of stamped parts and the cumulative tolerances introduced by welding and assembly processes, the tailgate requires adjustment during assembly to ensure clearance between it and the vehicle's side panels. Typically, the tailgate and hinges are secured to a positioning fixture, and the hinged tailgate is then mounted to the vehicle body in white. The tailgate's positioning reference is typically set on the side panels, and adjustments are then made by moving the hinges at the vehicle body end. This adjustment method ignores the requirements for the clearance between the tailgate trim and the side panels, making it impossible to determine if the tailgate trim and side panels are properly matched within the vehicle. Therefore, a tool is needed to detect the gap between the vehicle's side panels and the tailgate trim to improve tailgate installation accuracy. Utility Model Content

[0008] In some embodiments, each of the contoured members includes a second contoured plate, which is in contact with an end side of the tailgate. The end side is a side surface perpendicular to the axial direction of the tooling body and formed at the end of the tailgate.

[0009] In some embodiments, the tool body is in a cylindrical shape and is made of carbon fiber material.

[0010] In some embodiments, each of the positioning units and the detection unit is installed on the tooling body through a connecting piece, and the connecting piece includes a connecting block and a locking part, and the connecting block is slidably connected to the tooling body; the locking part is used to lock the relative position of the connecting block and the tooling body.

[0028] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] See also Figure 1 , Figure 1The figure is a schematic diagram of the overall structure of a tailgate and side panel gap detection tool in one embodiment of the present application. This embodiment of the present application provides a tailgate and side panel gap detection tool, comprising a tool body 10, two sets of detection units 30, and a plurality of positioning units 20. The two sets of detection units 30 are disposed at either end of the tool body 10, each detection unit 30 including at least one contoured member 31. The contoured member 31 matches the shape of the tailgate trim and can be inserted into the gap between the vehicle side panel and the tailgate. The assembly accuracy of the tailgate is determined by detecting the gap between the contoured member 31 and the side panel. The positioning units 20 are spaced apart and movable along the axial direction of the tool body 10. The positioning units 20 are used to position and install the tool body 10 and the tailgate.

[0030] In this embodiment, the axial direction of the tool body 10 extends along the width direction of the vehicle body. Figure 1 The X-direction is the axial direction of the tooling body 10, and the clearance between the body side and the tailgate is the clearance between the body side and the tailgate in the X-direction. The tailgate is provided with multiple positioning holes along the X-direction. Since the positioning units 20 can be moved axially along the tooling body 10, the distances between the positioning units 20 can be adjusted to match the distances between the positioning holes, allowing each positioning unit 20 to mate with the positioning holes on the tailgate to secure the fixture. The profiling member 31 of the detection unit 30 simulates the clearance between the tailgate trim and the body side when assembled on the tailgate, thereby accurately and effectively determining whether the tailgate's installation position meets the requirements. This tailgate-side clearance detection tool is compact and easy to handle during operation. The profiling member 31 quickly measures the clearance between the tailgate trim and the body side, aligning it with the body and tailgate, thereby improving tailgate assembly accuracy.

[0031] See also Figure 2 , Figure 2 yes Figure 1 Schematic diagram of the positioning unit structure in an embodiment. In some embodiments, each positioning unit 20 includes a positioning member 21, a locking pin 22, and a locking nut 23. The positioning member 21 is in contact with the surface of the tailgate and has a pin hole. The locking pin 22 passes through the pin hole and the positioning hole in the tailgate, and abuts against either the positioning member 21 or the tailgate. The locking nut 23 is threadedly connected to the locking pin 22, and abuts against the other of the positioning member 21 or the tailgate.

[0032] like Figure 1The Z direction shown is the axial direction of the locking pin 22, which also corresponds to the height of the tailgate. The Y direction is a reference direction perpendicular to the X and Z directions. It will be appreciated that during assembly, the locking pins 22 of each positioning unit 20 can be inserted into the positioning holes, allowing the positioning member 21 to contact the tailgate surface. This pre-positions the tailgate-side panel clearance detection tool to restrict movement of the tool body 10 relative to the vehicle body in the X or Y directions. Nuts are then used to securely connect each locking pin 22 to the tailgate, effectively restricting movement of the tool body 10 relative to the vehicle body in the Z direction, thereby achieving a secure connection between the tool body 10 and the tailgate. The following description uses the abutment of the locking pin 22 and the positioning member 21 as an example. The locking pin 22 has an abutment surface 221 that is larger than the pin hole area of ​​the positioning member 21. The locking pin 22 is inserted into the positioning hole of the tailgate from the side of the positioning member 21 facing away from the tailgate, so that the abutment surface 221 on the locking pin 22 abuts the positioning member 21. The locking nut 23 abuts the side of the tailgate facing away from the positioning member 21 and is threadedly connected to the locking pin 22. In other words, the tailgate and the positioning member 21 are clamped between the locking nut 23 and the abutment surface 221. In this way, a fixed connection between the tailgate and the tooling body 10 is achieved.

[0033] See also Figure 3 , Figure 3 yes Figure 1 Schematic diagram of the detection unit structure in an embodiment. In some embodiments, each profiling member 31 includes a first profiling plate 311, which is formed with a detection edge 3111 that simulates the contour of the tailgate trim. The assembly accuracy of the tailgate and the vehicle body side panel is determined by measuring the gap between the detection edge 3111 and the side panel.

[0034] In some embodiments, the actual gap between the detection edge 3111 and the side panel can be directly measured using a ruler and compared with the nominal gap value, which is the standard gap between the tailgate trim and the side panel. The difference between the actual and nominal gap values ​​determines whether the tailgate needs adjustment. Once the adjustment is satisfactory, the locking nut 23 is loosened and the auxiliary device is replaced. To further improve measurement accuracy, the detection unit 30 also includes a distance sensor (not shown). The distance sensor can be located on the detection edge 3111 of the first contour plate 311 to automatically measure the gap between the detection edge 3111 and the side panel.

[0035] Please continue reading Figure 3 Furthermore, each profiling member 31 includes a second profiling plate 312, which is aligned with the end side of the tailgate. The end side is a side surface formed at the end of the tailgate and perpendicular to the axial direction of the tooling body 10. The alignment of the second profiling plate 312 with the end side further positions the first profiling plate 311, ensuring its position relative to the tailgate in the X-direction, and thus accurately measuring the gap between the detection edge 3111 of the first profiling plate 311 and the side panel.

[0036] See also Figure 1 In some embodiments, the tool body 10 is in a cylindrical shape and is made of carbon fiber material. The tool body 10 made of carbon fiber material has the characteristics of high strength and light weight, which makes it easy for users to take and put the assistive device.

[0037] In some embodiments, each positioning unit 20 and detection unit 30 is installed on the tooling body 10 through a connecting member 40, and the connecting member 40 includes a connecting block 41 and a locking portion 42, wherein the connecting block 41 is slidably connected to the tooling body 10; the locking portion 42 is used to lock the relative position of the connecting block 41 and the tooling body 10.

[0038] See also Figure 2 In conjunction with the tubular design of the tooling body 10, each connecting block 41 includes a first curved portion 411 and a second curved portion 412. The first curved portion 411 and the second curved portion 412 are in the shape of a snap ring with an opening. The first curved portion 411 and the second curved portion 412 combine to form a through hole for the tooling body 10 to pass through. Threaded holes are provided at both ends of the first curved portion 411, and connecting holes are provided at both ends of the second curved portion 412. Two locking portions 42 are provided. The two locking portions 42 pass through the connecting holes at both ends of the second curved portion 412 and are threadedly connected to the threaded holes of the first curved portion 411. The side of the second curved portion 412 facing away from the first curved portion 411 abuts against the locking portion 42.

[0039] In other embodiments, the tooling body 10 may be a long strip structure with a rectangular, trapezoidal or other shaped cross-section, and the locking portion 42 may be a pneumatic locking structure, a cam locking pin 22 structure, or other locking structures familiar to those skilled in the art, which will not be described in detail here.

[0040] See also Figure 1 as well as Figure 2In some embodiments, the connecting block 41 is detachably fixedly connected to the positioning unit 20 and the detection unit 30. Specifically, the connection can be bolted. The positioning member 21 of the positioning unit 20 can be bolted to the second curved portion 412 of the connecting block 41. The contour member 31 of the detection unit 30 is fixedly connected to an adapter plate 32, which is bolted to the second curved portion 412. This detachable fixed connection facilitates replacement of individual positioning units 20 or detection units 30. Even if one positioning unit 20 or detection unit 30 is damaged, the entire device does not need to be replaced, saving costs. Furthermore, since the tailgate trim shapes of various new vehicles may vary, the contour member 31 of the detection unit 30 can be designed in a variety of styles. By detachably connecting the detection unit 30 to the connecting block 41, the clearance requirements between the tailgate trim and the vehicle side panel of different vehicle models can be met by simply replacing a different detection unit 30 to match the desired tailgate trim shape, thereby improving the versatility of the device.

[0041] See also Figure 1 In some embodiments, the tool body 10 includes a sleeve 11 and two telescopic rods 12, each of which is screwed to the ends of the sleeve 11. It is understood that by rotating the sleeve 11 and the telescopic rods 12 relative to each other, the axial length of the tool body 10 can be adjusted, thereby facilitating adaptation to vehicle models of different widths and facilitating storage.

[0042] Furthermore, the positioning units 20 are provided in three groups, one of which is located on the sleeve 11 , and the other two groups are symmetrically installed on the two telescopic rods 12 .

[0043] The above descriptions are only some embodiments of the present application and do not limit the scope of protection of the present application. Any equivalent device or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the scope of patent protection of this application.
