Description

Technical Field

[0001] This utility model relates to the field of vehicle seat technology, and in particular to a mating structure for quick installation of a vehicle body using a sliding rail. Background Technology

[0002] Seat rails are crucial mechanical components of seats. Commonly installed under the seats, they are used to adjust the fore-and-aft position of the seats, facilitating driver operation or providing passengers with more comfortable space. Furthermore, the seats connect to the vehicle body via the rails, requiring strong and rigid connections to maintain occupant posture during a collision, thus enhancing safety. Currently, the market primarily categorizes seat rails by travel distance into standard rails and long rails. Standard rails have a shorter travel distance, typically 180-260mm. Long rails are usually used in large SUVs or MPVs, handling the travel adjustment of one or more seats, and therefore have a longer travel distance, generally around 400mm to 1500mm.

[0003] Traditional seat rails are relatively short, with bolts connecting them to the vehicle floor at only two ends. Longer rails, however, are typically 3-5 times longer than traditional short rails. Continuing with the short-rail connection method would compromise the overall rigidity and strength of the seat, and the larger contact gap between the long rail and the vehicle body would cause various rattles and other noises. Therefore, existing long rail applications incorporate multiple intermediate fixing points, depending on the rail length, to address both strength and noise issues.

[0004] However, using the above connection method will increase the workload of vehicle body assembly on the one hand, and will also place more demands on the fit tolerance between the vehicle body and the slide rail on the other hand. Summary of the Invention

[0005] Therefore, this utility model provides a mating structure for quick installation of the vehicle body using a slide rail. By pre-installing connectors on the vehicle body mounting surface and setting corresponding openings on the slide rail mounting surface, the installation of multiple intermediate fixing structures can be completed at once by snapping the slide rail in place and then sliding it, thus saving assembly time and speeding up the vehicle body assembly cycle.

[0006] To solve the above-mentioned technical problems, this utility model provides a mating structure for quick installation of a vehicle body using a slide rail, comprising:

[0007] A vehicle floor plate, wherein threaded holes are provided on the vehicle floor plate;

[0008] A connector includes a connecting end and a clamping end, wherein the connecting end is provided with a threaded structure, and the threaded structure is adapted to be threadedly connected to the threaded hole.

[0009] A slide rail, wherein a plurality of mounting holes are provided along its length direction, and each mounting hole has a first hole segment and a second hole segment distributed along the length direction of the slide rail, the first hole segment and the second hole segment being connected;

[0010] The clamping end can extend from the first hole section. After the slide rail slides relative to the vehicle floor plate along the length direction, the second hole section is located above the clamping end. By tightening the connector, the clamping end can apply pressure to the slide rail, thereby clamping the slide rail.

[0011] In one embodiment, it also includes:

[0012] A nut is attached to the back of the vehicle body floor panel and near the second hole section, and the nut is provided with the threaded hole.

[0013] In one embodiment, the nut is welded to the back of the vehicle body floor.

[0014] In one embodiment, the vehicle body floor itself has a pre-drilled threaded hole.

[0015] In one embodiment, the opening size of the first hole segment to the second hole segment is constricted.

[0016] In one embodiment, the first hole is circular and its radial dimension is greater than the width dimension of the pressing end, and the second hole is oblong and its width dimension is smaller than the width dimension of the pressing end.

[0017] In one embodiment, the shape of the clamping end includes a circle or a hexagon; the connecting end is configured as a stud.

[0018] In one embodiment, the clamping end directly contacts the outer edge of the second hole segment.

[0019] In one embodiment, the connector further includes a first gasket, which is integrally formed with the connecting end and has a predetermined gap with the pressing end. The first gasket is located between the back of the slide rail and the front of the vehicle body floor.

[0020] In one embodiment, a second gasket is further included, which is connected to the slide rail and has an opening of the same size and shape as the mounting hole, and the clamping end abuts against the second gasket.

[0021] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0022] This utility model describes a mating structure for quick installation of a slide rail onto a vehicle body. By pre-setting threaded holes on the vehicle body floor plate and aligning them with mounting holes on the slide rail, the connector can be easily inserted and positioned via snap-fit ​​sliding. This eliminates the need for individually installing and positioning multiple fasteners, significantly simplifying the assembly process and enabling rapid, one-time installation of multiple intermediate fixing points. This substantially improves assembly efficiency and shortens the assembly cycle time on the vehicle production line. The snap-fit ​​and sliding installation method makes the positioning process between the slide rail and the vehicle body floor plate more convenient, reducing tedious manual alignment.

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0040] In this utility model, when directions (up, down, left, right, front, and back) are described, it is only for the convenience of describing the technical solution of this utility model, and does not indicate or imply that the technical features referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0041] In this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the stated number; "above," "below," "within," etc. are understood to include the stated number. In the description of this utility model, if "first" or "second" is used, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0042] In this utility model, unless otherwise explicitly defined, terms such as "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; a fixed connection, a detachable connection, or an integrally formed connection; a mechanical connection, an electrical connection, or a connection capable of mutual communication; or the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model based on the specific content of the technical solution.

[0043] Reference Figures 1 to 3As shown in the figure, a fitting structure for quick installation of a vehicle body using a slide rail according to an embodiment of the present invention includes a vehicle body base plate 1, a connector 2, and a slide rail 3. The vehicle body base plate 1 is provided with a threaded hole 11. The connector 2 includes a connecting end 21 and a pressing end 22. The connecting end 21 is provided with a threaded structure, which is adapted to be threadedly connected to the threaded hole 11. The slide rail 3 is provided with a plurality of mounting holes 31 along its length direction. Each mounting hole 31 has a first hole segment 311 (large hole end) and a second hole segment 312 (small hole end) distributed along the length direction of the slide rail 3. The first hole segment 311 and the second hole segment 312 are connected. The pressing end 22 can extend out from the first hole segment 311. After the slide rail 3 slides relative to the vehicle body base plate 1 along its length direction, the second hole segment 312 is located above the pressing end 22. By tightening the connector 2, the pressing end can apply pressure to the slide rail, thereby pressing the slide rail 3.

[0044] By pre-setting threaded holes 11 on the vehicle body floor 1 and matching the mounting holes 31 on the slide rail 3, the connector 2 can be easily inserted and positioned by snap-fit ​​sliding. This eliminates the need to install and position multiple fasteners one by one, greatly simplifying the assembly process and enabling rapid one-time installation of multiple intermediate fixing points. This significantly improves assembly efficiency and shortens the assembly cycle time of the vehicle production line. The snap-fit ​​and sliding installation method makes the positioning process between the slide rail 3 and the vehicle body floor 1 more convenient, reducing tedious manual alignment.

[0045] It should be noted that the mating structure for quick installation of the slide rail 3 on the vehicle body is suitable for long slide rails (generally 400mm~1500mm), and can also be used on slide rails 3 of other lengths as needed. The slide rail 3 is provided with the required number of mounting holes 31 (such as more than three).

[0046] In one embodiment, refer to Figure 3 As shown, a nut 4 is also welded to the back of the vehicle body floor 1 near the second hole segment 312, and the nut 4 is provided with the threaded hole 11. Alternatively, the threaded hole 11 may be pre-drilled in the vehicle body floor 1 itself.

[0047] In one embodiment, to achieve a snap-fit ​​sliding fit between the mounting hole 31 and the connector 2, the opening size of the first hole segment 311 to the second hole segment 312 is tapered. For example, referring to... Figure 4 As shown, the first hole segment 311 is circular and its radial dimension is larger than the width dimension of the pressing end 22, the second hole segment 312 is oblong and its width dimension is smaller than the width dimension of the pressing end 22, and the overall shape of the mounting hole 31 is "gourd".

[0048] Furthermore, the symmetrical cross-sections of the first hole segment 311 to the second hole segment 312 coincide, making the mounting holes 31 symmetrical. Multiple mounting holes 31 are distributed along the same straight line and located on the center line of the slide rail 3.

[0049] It should be noted that the shape of the mounting hole 31 is not limited to the shape described above. For example, it can be set as two circles of different sizes and an elongated hole connected to them, or two circles of different sizes and a transitional shrinkage structure connected to them.

[0050] In one embodiment, the shape of the clamping end 22 is preferably circular or hexagonal, and the clamping end 22 is provided with a structure for tightening the connector 2 with a suitable tool (such as an internal or external hex wrench), and the connecting end 21 is configured as a stud.

[0051] In one embodiment, the clamping end 22 directly contacts the outer edge of the second hole segment 312.

[0052] In one embodiment, refer to Figure 7 , Figure 8 As shown, the connector 2 also includes a first gasket 23, which is integrally formed with the connecting end 21 and has a predetermined gap with the pressing end 22. The first gasket 23 is located between the back of the slide rail 3 and the front of the vehicle body floor 1.

[0053] With the above settings, if the height of the reserved positions at the front and rear of the vehicle body floor 1 is inconsistent, the height difference can be compensated by setting the first shim 23; in addition, in order to achieve the limiting function, a groove for accommodating the first shim 23 is provided on the front of the vehicle body floor 1.

[0054] In one embodiment, refer to Figure 3 As shown, it also includes a second gasket 5, which is connected to the slide rail 3 and has an opening corresponding to the mounting hole 31 (shape and size). The second gasket 5 is pre-welded to the front of the slide rail 3, and the pressing end 22 abuts against the second gasket 5.

[0055] By setting the first shim 23 and / or the second shim 5, the height difference and assembly tolerance between the vehicle body floor 1 and the slide rail 3 can be effectively compensated, the tightness of the fit between the connector 2 and the slide rail 3 and the vehicle body floor 1 can be improved, and the smoothness of the assembly process and the structural stability of the finished product can be ensured.

[0056] It should be noted that, referring to Figure 5 , Figure 6As shown, to avoid the mounting holes 31 affecting the strength of the slide rail 3, and to ensure the connection strength between the slide rail 3 and the vehicle body floor 1, for example, in a specific design, the length of the slide rail 3 is 400mm-1500mm, the spacing L1 between the mounting holes 31 is 150mm-350mm, which can achieve a good balance between structural strength and assembly convenience, and avoid the effective cross-sectional area of ​​the slide rail 3 being reduced due to overly dense hole positions. The length L2 of the mounting holes 31 is 18mm-30mm.

[0057] The maximum width L3 of the mounting hole 31 is 1 / 3 to 1 / 2 of the width L4 of the slide rail 3.

[0058] In addition, the maximum width L3 of the first hole section 311 is set to be 1~2 mm larger than the maximum width L6 of the clamping end 22 of the connector 2, so that the connector 2 can pass smoothly through the first hole section 311.

[0059] The maximum width L5 of the second hole section 312 is 2mm to 3mm smaller than the maximum width L6 of the pressing end 22, so that when the connector 2 is tightened, the pressing end 22 can reliably contact the outer edge of the second hole section 312, thereby achieving the effect of pressing and locking the slide rail 3.

[0060] The maximum width L5 of the second hole section 312 is 1mm to 2mm greater than the maximum width L7 of the connecting end 21, which facilitates the smooth sliding of the slide rail 3. This structural design not only simplifies the assembly process but also ensures connection strength and structural safety.

[0061] The assembly process in this embodiment is as follows:

[0062] Threaded holes 11 are pre-machined at the corresponding installation positions on the vehicle chassis 1, or nuts 4 are fixed on the back of the vehicle chassis 1 by welding, so that the vehicle chassis 1 has a threaded interface that matches the threaded structure of the connector 2. The connecting end 21 of the connector 2 is securely installed into the threaded hole 11 or the welded nut 4 on the vehicle chassis 1 by threaded connection.

[0063] Align each of the first hole segments 311 of the slide rail 3 with the clamping ends 22 of each of the connectors 2 that are pre-installed on the vehicle body floor 1, so that the clamping ends 22 of the connectors 2 can smoothly pass through the first hole end of the slide rail 3.

[0064] Slide the slide rail 3 along its length so that the clamping end 22 of the connector 2 slides from the first hole end to directly below the second hole end. At this time, the second hole ends of each mounting hole 31 of the slide rail 3 are located above the clamping end 22 of the corresponding connector 2 and are effectively limited by it.

[0065] Use a suitable tool (such as a wrench) to tighten the connector 2. As the connector 2 is tightened, its pressing end 22 gradually rises and forms a pressing fit with the outer edge of the second hole end of the slide rail 3, reliably pressing the slide rail 3 against the surface of the vehicle body floor 1, achieving a stable connection at multiple points in the middle. If there is a height difference or gap between the slide rail 3 and the vehicle body floor 1, it can be compensated by the first shim 23 or the second shim 5 to further improve the pressing effect and the fit of the assembly.

[0066] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
