Description

Technical Field

[0001] The invention relates to the field of automobile parts installation, in particular to an automobile tailgate latch positioning tool. Background Art

[0002] During actual vehicle assembly, the tailgate latch must be secured to the vehicle body. The tailgate latch's mounting point is a crucial component of the vehicle's structure. The latch's installation determines the clearance and surface difference between the tailgate and the vehicle body. A flexible, adjustable tailgate latch mounting structure can better ensure the desired clearance between the tailgate and the side panels. Therefore, auxiliary tooling is currently widely used for positioning and tightening during tailgate latch assembly.

[0003] There are two common methods of assembly currently available: using magnets to attach the fixture to the vehicle body; and directly welding the fixture to the vehicle body. However, extensive installation experience has shown that both methods have significant drawbacks. For example, the first method cannot be used on vehicles with aluminum bodies, and the second method cannot adjust the locking nuts.

[0004] This is because current manufacturing processes commonly encounter issues such as tailgate latch position deviation during assembly, improper assembly, and uneven clearance between the tailgate and the latch. Consequently, the two most common assembly methods directly impact the inability to adjust tailgate clearances caused by manufacturing deviations, and can even lead to interference between the tailgate and the side panels. This necessitates constant readjustment of the tailgate latch, increasing labor hours and reducing efficiency. Furthermore, existing tailgate latch positioning tooling is single-use and cannot be used across multiple vehicle models. Furthermore, adding a set of tooling per vehicle model requires a significant increase in the production line area. Summary of the Invention

[0005] In response to the problems existing in the prior art, the present invention proposes a new technical solution, namely, a car tailgate lock positioning tool to solve the problems that the current positioning tool is inconvenient to adjust and cannot be shared by multiple models.

[0025] Furthermore, the template is further provided with a limiting sliding groove and a limiting sliding tongue; the limiting sliding groove is penetrated by the clamping slot;

[0026] The limiting sliding tongue is provided with a bar-shaped hole for adjustment and fixation and a bayonet for corresponding to the bayonet slot; the limiting sliding tongue can be adjusted and slid in the limiting sliding slot so that the bayonet locates the installation position of the tailgate lock buckle.

DETAILED DESCRIPTION

[0041] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples provided are intended only to explain the present invention and are not intended to limit the scope of the present invention. To enable those skilled in the art to better understand the technical solutions of the present technology, the present technology is described in detail below with reference to the accompanying drawings. The description in this section is merely exemplary and explanatory and should not have any limiting effect on the scope of protection of the present technology.

[0042] This embodiment provides a car tailgate lock positioning tool, which is used to achieve a snap connection with the tailgate lock, thereby achieving precise installation of the tailgate lock.

[0043] This is because current manufacturing processes commonly encounter issues such as tailgate latch position deviation, improper assembly, and uneven clearance between the left and right tailgates. Common assembly methods cannot adjust for tailgate clearances caused by manufacturing deviations, and can even cause interference between the tailgate and the side panels. This requires operators to constantly readjust the tailgate latch position, increasing work hours and reducing efficiency. Furthermore, existing tailgate latch positioning tooling is single-use and cannot be used across multiple vehicle models. Furthermore, adding a set of tooling per vehicle model requires a significant increase in the production line area.

[0044] In order to better deal with the above problems, here is a car tailgate lock positioning tool. For ease of understanding, see Figure 1 - Figure 2Here, the composition structure of the tailgate lock is introduced, that is, the tailgate lock structure includes a buckle plate 101, a ring buckle 102 and a locking screw 103; the outer structure of the buckle plate 101 is roughly elliptical, and mounting holes are provided on the left and right sides of the buckle plate 101. There are two locking screws 103, and each locking screw 103 passes through the mounting hole here and is screwed and fixed to the vehicle body 104; the ring buckle 102 is fixed on the buckle plate 101 here and is located between the two mounting holes. The ring buckle 102 protrudes and extends upward to facilitate snap-fitting with the card slot 401 in the positioning tool.

[0045] In this embodiment, the positioning tooling includes a positioning plate 200, a positioning arm 300 and a positioning block 400; the positioning plate 200 serves as a base plate for installing and fixing the positioning arm 300 and the positioning block 400. At the same time, the positioning plate 200 here can be stably fitted with the surface of the vehicle body, providing a reliable basis for subsequently determining the specific position of the tailgate lock.

[0046] For details, see Figure 3 The positioning plate 200 here is a long plate-shaped structure; the positioning arms 300 and the positioning block 400 are both installed on the positioning plate 200, that is, in this embodiment, the positioning arms 300 are respectively arranged at the left and right ends of the positioning plate 200, and the two positioning arms 300 are both configured to be adjustable along the length direction of the positioning plate 200; the positioning arms 300 position the positioning tooling on the vehicle body of different models; the positioning block 400 is connected to the positioning plate 200 and is located between the two positioning arms 300, and at the same time, a slot 401 is provided in the positioning block 400, and the slot 401 is configured to locate the installation position of the tailgate lock.

[0047] For ease of understanding and subsequent description, we can define the length direction of the positioning plate 200 as the Y direction. It is not difficult to conclude that the width direction of the positioning plate 200 can be defined as the X direction. In this embodiment, the two positioning arms 300 are configured to be adjustable along the length direction of the positioning plate 200. It can be understood that the two positioning arms 300 are connected to the positioning plate 200 and can also move in the same direction or opposite directions along the Y direction. By designing the positioning arms 300 here as an adjustable structure, the tooling can adapt to and position different vehicle models.

[0048] In this solution, the two positioning arms 300 are able to move in the Y direction via a drive mechanism 500. Specifically, when the vehicle model changes, the operator activates the drive mechanism 500 to move the two positioning arms 300. Specifically, the positioning fixture also includes a drive mechanism 500 located on the back of the positioning plate 200. The drive mechanism 500 simultaneously drives the positioning arms 300 on both ends of the positioning plate 200, causing the two positioning arms 300 to move toward or away from each other.

[0049] The two positioning arms 300 are adjustable and are adjusted by the drive mechanism 500. This is because different vehicle models may have different positioning points with different spacing between them. Therefore, when positioning the tailgate latch for a specific vehicle model, it is necessary to first adjust the spacing between the two positioning arms 300 so that the spacing between them meets the requirements of the current vehicle model. Then, the spacing between the two positioning arms 300 in the positioning tooling is maintained to achieve batch positioning for subsequent assembly of similar vehicles.

[0050] For details, see Figure 4 The drive mechanism 500 includes an actuating rod 501, which is movably connected to the back of the positioning block 400 and is adjustable in the vertical direction relative to the positioning plate 200. The vertical direction here can be understood as the Z direction, that is, the actuating rod 501 can move up and down in the Z direction. The proposed drive mechanism 500 also includes two connecting rods 502, each of which is hinged to the actuating rod 501; the connecting rods 502 and the actuating rod 501 form a "human" structure; the drive mechanism 500 also includes sliding rods 503, which correspond one-to-one with the connecting rods 502, and each sliding rod 503 is hinged to the distal end of the corresponding connecting rod 502; the free end of each sliding rod 503 is connected to the corresponding positioning arm 300.

[0051] During use, the positioning arms 300 can be moved by applying force to the actuating rod 501. For example, when the two positioning arms 300 move away from each other, the operator applies force to the actuating rod 501, causing it to move downward in the Z direction. This downward movement of the actuating rod 501 causes the two hinged connecting rods 502 to open, causing the two connecting rods 502 to push their respective slide rods 503 away from each other in the Y direction. This away movement of the slide rods 503 gradually increases the distance between the positioning arms 300, accommodating vehicles with longer spacing between positioning points.

[0052] Similarly, if the spacing between the positioning points of a certain type of vehicle is shorter, it is necessary to apply force to the action rod 501 so that the action rod 501 moves upward along the Z direction. During the upward movement of the action rod 501, the two hinged connecting rods 502 move closer together, and the two connecting rods 502 pull their respective sliding rods 503 to move toward each other along the Y direction. The toward-together movement between the sliding rods 503 gradually shortens the spacing between the positioning arms 300.

[0053] In this embodiment, see Figure 5The structure of the positioning arm 300 is also designed, that is, the positioning arm 300 includes a main body 301, a base 302, a rotating block 303, a sliding block 304 and a positioning pin 305 fixed on the sliding block 304; the positioning arm 300 and the positioning point on the vehicle body are positioned, which is actually completed through the positioning pin 305 here, that is, under the joint action of the driving mechanism 500, the main body 301, the base 302, the rotating block 303 and the sliding block 304, the positioning pin 305 can be plugged and matched with the positioning points on the vehicle bodies of different models, thereby completing the alignment and positioning of the tooling.

[0054] Specifically, in the positioning arm 300, the body 301 is connected to the slide rod 503 in the aforementioned drive mechanism 500. Therefore, when the slide rod 503 pushes or pulls the positioning arm 300, it is actually the slide rod 503 pushing or pulling the body 301. The base 302 is U-shaped and fixed to the distal end of the body 301. The distal end here specifically refers to the end of the body 301 away from the slide rod 503. The base 302 and the body 301 form an L-shaped structure. The rotating block 303 is hinged between the two side walls of the base 302 via a connecting shaft. It can be understood that the U-shaped design of the base 302 is primarily intended to facilitate the connection of the rotating block 303, allowing it to be flexibly connected between the two side walls of the base 302. The rotating block 303 can also be rotated around its own axis via the connecting shaft, further enhancing the applicability of the tooling.

[0055] It should be noted that in this embodiment, the rotating block 303 can rotate around its own axis through the connecting shaft. Specifically, the axis of the connecting shaft is parallel to the Y-direction line. Therefore, the rotation of the rotating block 303 around its own axis can also be understood as rotation around an axis parallel to the Y-direction line.

[0056] A sliding groove is provided on the end surface of the rotating block 303 facing the vehicle body; at the same time, a dovetail slide is provided on the sliding block 304, and the dovetail slide cooperates with the sliding groove to make the position of the positioning pin 305 adjustable.

[0057] It can be understood that the sliding block 304 can slide on the rotating block 303 to adjust the position of the positioning pin 305 .

[0058] At this point, it can be summarized as follows: in order to achieve the positioning of the tooling and different vehicle models, the positioning pin 305 is used to plug and position with the positioning points on the vehicle bodies of different vehicle models, and the positioning pin 305 can achieve translational adjustment along the Y direction under the action of the driving mechanism 500; the positioning pin 305 can rotate around the axis parallel to the Y direction under the action of the rotating block 303, and the positioning pin 305 can also move along the extension direction of the dovetail slide (which can be equivalent to the X direction) under the action of the sliding block 304; therefore, in the solution proposed in this solution, in order to adapt to the positioning of different vehicle models, the proposed positioning pin 305 can be translated in the X and Y directions, and can also be rotated around the axis parallel to the Y direction.

[0059] Optionally, in order to enhance the overall strength of the tool, especially to improve the strength of the positioning arm 300 , the main body 301 and the holder 302 in this embodiment are an integrally formed structure.

[0060] In this solution, in order to improve the stability of the positioning arm 300 sliding on the positioning plate 200, a slide is provided at the bottom of the main body 301; at the same time, a stepped surface matching the slide is opened on the positioning plate 200, so that the slide is placed on the stepped surface and slides.

[0061] The cooperation between the slide and the step surface is not only conducive to the stable sliding of the positioning arm 300, but also the step surface between the slide and the step surface can be used to form a limit; for example, in the present embodiment, a first step surface is formed on the right side of the step surface, and a second step surface is also formed on the left side of the slide. The two step surfaces restrict each other, so that when the main body 301 slides on the positioning plate 200, it is restricted by the first step surface and the second step surface, so that the positioning arm 300 can always move within a preset reasonable range; in this way, the adjustable range of the positioning pin 305 is always within a certain range.

[0062] In this solution, after the positioning arm 300 is used to complete the positioning on the vehicle body, the positioning block 400 here needs to be used to determine the specific position of the tailgate lock.

[0063] In this embodiment, see Figure 6 - Figure 7 The positioning block 400 includes an adapter seat 402 and a template 403; wherein the adapter seat 402 is connected to the positioning plate 200; the template 403 is fixed on the adapter seat 402 and tilted downward relative to the adapter seat 402. The installation position slot 401 for positioning the tailgate lock mentioned above runs through the template 403 opened here.

[0064] It can be understood that in this solution, a certain angle is formed between the adapter 402 and the template 403. Through such a design, the card slot 401 can be in a better position to determine the specific position of the tailgate lock.

[0065] In this embodiment, the mold plate 403 is further provided with a limiting slot 404 and a limiting tongue 405. The limiting slot 404 is penetrated by the latch 401. The limiting tongue 405 is positioned within the limiting slot 404 primarily to further determine the specific position of the tailgate latch. Specifically, the limiting tongue 405 is provided with a bar-shaped hole 406 for adjustment and fixation, and a latch 407 that aligns with the latch 401. The limiting tongue 405 can be adjusted and slid within the limiting slot 404, allowing the latch 407 to locate the tailgate latch's installation position.

[0066] The specific installation method is: first loosen the fastening screw locked in the strip hole 406 so that the limiting sliding tongue 405 can slide in the limiting sliding groove 404, and by adjusting the position of the limiting sliding tongue 405 in the limiting sliding groove 404, determine the specific position of the ring buckle 102 in the tailgate lock buckle. After the ring buckle 102 abuts against the card slot 401 here, tighten the fastening screw in the strip hole 406 to fix the position of the limiting sliding tongue 405 in the limiting sliding groove 404.

[0067] At the same time, in this solution, a pad 410 is also provided in the limiting slide groove 404. The pad 410 is adjustably provided in the limiting slide groove 404 and can prevent the limiting sliding tongue 405 from loosening. This is because the limiting sliding tongue 405 is fixed in the limiting slide groove 404 by the cooperation of a fastening screw and a strip-shaped hole 406. The fastening screw is very likely to loosen during long-term use. At this time, if there is no pad 410 to support it, the limiting sliding tongue 405 will loosen, making the positioning position no longer accurate. This requires the reorganization of manpower and material resources for repositioning, affecting processing efficiency.

[0068] Therefore, the present invention proposes a design of a pad 410, and installs the pad 410 in the limiting slide groove 404. First, the installation position of the limiting slide tongue 405 is determined by adjusting the pad 410 and the limiting slide tongue 405 at the same time; then the limiting slide tongue 405 is fixed. At this time, one end of the limiting slide tongue 405 will always abut against one end of the pad 410. The pad 410 here can effectively reduce the possibility of loosening and position deviation of the limiting slide tongue 405, which has a great promoting effect on ensuring the service life and positioning accuracy of the entire tooling.

[0069] See also Figure 3 、 Figure 7, the pad 410 is fixed and adjusted by the machine screw 411; in this solution, the machine screw 411 is set on the adapter 402, and the abutting end of the machine screw 411 passes through the adapter 402 until it reaches the limiting slide groove 404, and the abutting end of the machine screw 411 will abut the end face of the pad 410 here. By adjusting the machine screw 411, the position of the pad 410 in the limiting slide groove 404 can be adjusted, so that the pad 410 can provide more stable support for the limiting sliding tongue 405.

[0070] In this solution, the positioning block 400 is configured to be fine-tunable along the length of the positioning plate 200. It can be simply understood that in order to achieve positioning adjustment and compatibility with different vehicle models, the positioning block 400 proposed in this solution can also be adjusted to a certain extent in the Y direction.

[0071] For details, see Figure 8 A threaded hole is provided at the bottom of the adapter 402 of the positioning block 400, and a countersunk hole is provided on the positioning plate 200 at a location corresponding to the positioning block 400. These countersunk holes are strip-shaped, extending parallel to the Y direction. When securing the positioning block 400, the locking mechanism can be offset within the countersunk hole, allowing for fine-tuning of the entire positioning block 400 in the Y direction.

[0072] Thus, it can be concluded that this solution also provides multiple adjustment options for the positioning block 400 to accommodate different vehicle models. The positioning block 400 can be adjusted in two ways: first, the entire positioning block 400 can be fine-tuned along the Y direction on the positioning plate 200. Second, the limiting sliding tongue 405 installed in the limiting slide 404 can be slid and adjusted within the limiting slide 404. These two adjustment methods further facilitate the determination of the tailgate latch's installation position.

[0073] The positioning block 400 is provided here to be adjustable in the Y direction, and the problem of loosening of the locking screw also needs to be considered. That is, after long-term use, if the locking screw in the countersunk hole is loose, the position of the entire positioning block will be offset, and the positioning position of the slot 401 will eventually be inaccurate. Therefore, in order to avoid this situation, a block limit plate 408 is proposed in this solution.

[0074] Specifically, two mold block limiting plates 408 are fixed on the positioning plate 200. The two mold block limiting plates 408 are respectively fixed on the left and right sides of the positioning mold block 400. The mold block limiting plates 408 here can be used to fix the position of the fixed positioning mold block 400.

[0075] In this solution, there are multiple ways to use the block limiting plate 408 to limit the position of the positioning block 400, and two of them are introduced here.

[0076] Method 1: Each block limiting plate 408 is spaced apart from the positioning block 400; an adjustment screw 409 is provided in the block limiting plate 408, which is used to position and limit the fine-tuning position of the positioning block 400. Specifically, during use, the adjustment screw 409 is rotated so that one end of the adjustment screw 409 rests against the side wall of the positioning block 400. At this time, the adjustment screws 409 on both sides simultaneously apply force to the positioning block 400, restricting the fixed position of the positioning block 400. This effectively reduces the positional deviation of the positioning block 400 caused by loosening of the locking screws.

[0077] Method 2: The block limiting plates 408 here can be set as an adjustable structure; that is, the block limiting plates 408 can be slidably set on the positioning plate 200. After the positioning block 400 completes the positioning and fixing of the position, the block limiting plates 408 on the left and right sides are adjusted to lean against the adapter 402 of the positioning block 400, and the block limiting plates 408 are directly used to fix and limit the position of the adapter 402.

[0078] The block limiting plate 408 is slidable. The specific design structure can be to provide a sliding groove on the positioning plate 200, the extension direction of the sliding groove being parallel to the length direction of the positioning plate 200 (that is, parallel to the Y direction), and then fix a slide rail that matches the slide rail in the block limiting plate 408. In this way, the mutual cooperation between the sliding groove and the slide rail enables the block limiting plate 408 to be adjusted and moved. Of course, after the block limiting plate 408 is adjusted into place, it is necessary to fix the position of the block limiting plate 408. In this case, a locking bolt can be installed on the side wall of the positioning plate 200, and the locking bolt can be rotated until it enters the sliding groove and abuts the slide rail. In this way, the position of the block limiting plate 408 can be fixed by the locking bolt.

[0079] In summary, the tailgate latch positioning tool provided by this technical solution is simple in structure, quick and easy to use, and can complete final positioning in a single use. This effectively avoids the problem of repeated adjustment of the latch after the tailgate is installed, reducing the phenomenon of repeated manual operations that reduce work efficiency. At the same time, the positioning arm and positioning block in the tailgate latch positioning tool are adjustable, and can be adaptively adjusted according to different vehicle models, making the tailgate latch positioning tool proposed in this solution compatible with multiple vehicle models.
