[0024] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details.

[0025] This disclosure provides a tooling for centering a tailgate in the Y direction, comprising a base plate 1. The base plate 1 includes a first side and a second side disposed opposite to each other. The first side is provided with a slide rail 20 and a displacement measuring component. A sliding component is provided on the slide rail 20. The sliding component is used to contact the tailgate and is movable along the slide rail 20. The displacement measuring component is used to measure the displacement of the sliding component. Thus, the positions of the left and right ends of the tailgate in the Y direction relative to the vehicle body can be obtained through the sliding component and the displacement measuring component.

[0026] The second side of the substrate 1 is provided with a snap-fit ​​assembly for snap-fit ​​connection to the vehicle body. Multiple positioning parts 42 are distributed on the second side for positioning and engaging with the vehicle body. Thus, the tooling can be quickly connected to the vehicle body via the snap-fit ​​assembly, and the multiple positioning parts 42 facilitate accurate positioning of the tooling.

[0027] Optionally, the snap-fit ​​assembly includes a first post 411, one end of which is fixedly connected to the second side of the base plate 1, and the other end is provided with a hook 412, which is used to engage with the connection hole of the vehicle body. Thus, the tooling is quickly snapped onto the vehicle body via the hook 412. For example, the connection hole is a through-hole structure provided in the vehicle body, and the hook 412 engages with the radially outer side wall of the connection hole, which is formed by the vehicle body located radially outside the connection hole.

[0028] Optionally, the substrate 1 includes a plurality of positioning connection parts, which are used to connect the positioning parts 42. The center points of the positioning connection parts corresponding to any three positioning parts 42 are not on the same straight line. Thus, the plurality of positioning connection parts are distributed on the substrate 1, which facilitates positioning in the Y and Z directions through the plurality of positioning connection parts, and avoids the substrate 1 from shifting or deflecting.

[0029] Optionally, the positioning part 42 includes a second column 421, one end of which is fixedly connected to the second side of the base plate 1. The vehicle body is provided with positioning holes and positioning grooves. For at least one positioning part 42, the other end of its second column 421 is provided with a positioning pin 422, which is used to position and engage with the positioning hole. For at least another positioning part 42, the other end of its second column 421 is provided with a positioning block 423 having a positioning surface 424, which is used to position and engage with the positioning groove.

[0030] For example, the substrate 1 is provided with four positioning parts 42, which are arranged in a quadrilateral pattern on the substrate 1. For example, the four positioning parts 42 are arranged in a roughly rectangular, square, or rhomboid pattern on the substrate 1. Three of the positioning parts 42 have positioning pins 422 on their second pillars 421. The positioning pins 422 of the three positioning parts 42 can be positioned and engaged with the positioning holes of the vehicle body. The three positioning parts 42 are arranged in a triangular pattern on the substrate 1, which can prevent the substrate 1 from undergoing undesirable deflection or offset. This ensures that the substrate 1 is accurately positioned at least in the Y and Z directions, and thus the tooling is accurately positioned at least in the Y and Z directions. The second pillar 421 of the other positioning part 42 is provided with a positioning block 423 having a positioning surface 424. The positioning block 423 engages with the positioning groove of the vehicle body through its positioning surface 424, which can accurately position the substrate 1 in the X direction, and thus the tooling is accurately positioned at least in the X direction.

[0031] The positioning part 42 with positioning pin 422 also includes an auxiliary positioning block 427. Specifically, the second column 421 of the positioning pin 422 is provided with an auxiliary positioning block 427, and the positioning block is provided with positioning pin 422. The auxiliary positioning block 427 is used to cooperate with the auxiliary positioning groove of the vehicle body to facilitate the positioning of the base plate 1 and facilitate the smooth insertion of the positioning pin 422 into the positioning hole of the vehicle body.

[0032] For at least one positioning part 42, a distance adjustment pad 425 is provided between the second column 421 of the positioning part 42 and the second side of the substrate 1. The distance adjustment pad 425 is used to adjust the distance between the second column 421 and the second side of the substrate 1. Optionally, the distance adjustment pad 425 is connected to an adjustment bolt 426, which is connected to the substrate 1. The extension thickness of the distance adjustment pad 425 is adjusted by tightening or loosening the adjustment bolt 426, thereby adjusting the distance between the corresponding second column 421 and the second side of the substrate 1.

[0033] Optionally, the distance adjustment pad 425 is an elastic pad, such as a rubber pad or an organic silicone pad.

[0034] Optionally, the plurality of second pillars 421 may have the same or different lengths to accommodate different vehicle body structures.

[0035] Optionally, a spring 25 is provided on the first side of the base plate 1. The spring 25 is used to apply a restoring force to the sliding assembly. One end of the spring 25 is connected to the sliding assembly, and the other end is fixedly connected to the base plate 1. The extension direction of the spring 25 is the same as the extension direction of the slide rail 20. Specifically, during the tailgate installation process, two fixtures are fixedly connected to both sides of the vehicle body, especially the rear sides of the vehicle body, through their respective base plates 1. Preferably, the slide rail 20 on the fixture extends basically along the Y direction. When the tailgate contacts the sliding assembly, the sliding assembly is displaced along the slide rail 20 in a direction away from the vehicle body under the action of the tailgate. At the same time, the spring 25 undergoes elastic deformation due to the restoring force from the sliding assembly and applies a reaction force, i.e., the restoring force, to the sliding assembly. Under the action of this reaction force, the sliding assembly automatically maintains contact with the tailgate. The restoring force can be the tensile force generated by the stretching deformation of the spring 25 or the compressive force generated by the compressive deformation. After the tailgate is removed, the sliding assembly returns to its original position under the action of the spring 25.

[0036] Optionally, the sliding assembly includes a slider 21 and a limiting member 22 connected to each other. The slider 21 is slidably connected to the slide rail 20 and can reciprocate along the slide rail 20. The limiting member 22 is provided with a tailgate contact portion 23, which is used to contact the tailgate. The position of the tailgate contact portion 23 relative to the limiting member 22 in the extension direction along the slide rail 20 is adjustable or fixed. Thus, during the tailgate installation process, the tailgate contacts the tailgate contact portion 23 on the limiting member 22 and pushes the limiting member 22 to move through the tailgate contact portion 23.

[0037] Optionally, the tailgate contact portion 23 includes a tailgate contact side 230 and another side disposed opposite to the tailgate contact side 230 in the extension direction of the slide rail 20, wherein the tailgate contact side 230 is the side of the tailgate contact portion 23 used to contact the tailgate.

[0038] For example, the tailgate contact portion 23 includes a connecting portion 231 connected to the limiting member 22. An adjusting shim 232 may be provided between the connecting portion 231 and the limiting member 22, and the adjusting shim 232 is located between the connecting portion 231 and the limiting member 22 in the extending direction of the slide rail 20. Optionally, the adjusting shim 232 is connected to a bolt, which is connected to at least one of the tailgate contact portion 23 and the limiting member 22. The thickness of the adjusting shim 232 is adjusted by tightening or loosening the bolt, thereby adjusting the position of the tailgate contact portion 23 relative to the limiting member 22 in the extending direction of the slide rail 20.

[0039] Optionally, the limiting member 22 further includes a fixing part 24, which is fixedly connected to the slider 21.

[0040] Optionally, the displacement measuring component includes a measuring gauge 31, which includes a connecting rod 32 connected to the sliding component. The connecting rod 32 moves with the sliding component, and the measuring gauge 31 measures the displacement generated by the sliding component.

[0041] In an alternative example, the displacement measurement component includes a laser measurement component for measuring the displacement state of the sliding component and generating displacement information for indicating the amount of displacement of the sliding component.

[0042] Optionally, the fixture further includes a prompting component, which is used to indicate whether the tailgate is in a Y-axis centered state or not, based on the displacement information. Optionally, the fixture includes a processing unit, which can acquire displacement information generated by the laser measurement component, identify whether the tailgate is in or not in a Y-axis centered state based on the displacement information corresponding to the two fixtures, and generate prompting information based on whether the tailgate is in or not in a Y-axis centered state, so that the prompting component can provide a prompt based on the prompting information.

[0043] Optionally, the prompting component includes a prompt light and / or a voice prompting component. The prompt light can generate different colored lights according to the prompting information, and the voice prompting component can generate different prompting sounds or provide voice prompts according to the prompting information.

[0044] Optionally, the prompting information includes offset information, which indicates the offset of the tailgate relative to its Y-axis centering position. The tooling may also include a display component for displaying the offset information. Optionally, the voice prompt component can provide offset prompts based on the offset information.

[0045] Optionally, a handle 5 is provided on the first side of the substrate 1 to facilitate the user to move the tool by gripping the handle 5.

[0046] The above description is merely an embodiment of this application and is 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.

[0047] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended claims.
