Description

Technical Field

[0001] This utility model relates to the field of door lock installation technology, and in particular to a nut plate and a door lock installation structure having the same, and an automobile. Background Technology

[0002] When installing door latches inside the B-pillar of the vehicle body, a pre-installed nut plate is typically used. This nut plate has a nut with a threaded hole aligned with a pre-drilled hole in the B-pillar sheet metal. To install the door latch, bolts are passed through the holes in the B-pillar and the nut plate to secure it to the B-pillar. This installation method requires the nut plate to be fixed inside the B-pillar with the nut aligned with the pre-drilled hole in the B-pillar for easy bolt insertion. Currently, a nut box is commonly used to hold the nut plate inside the B-pillar. The nut box and the B-pillar sheet metal enclose a space, and the nut plate is movably installed within this space. This allows for fine-tuning of the nut's position and alignment with the hole in the sheet metal during bolt insertion.

[0003] However, the way the nut plate is installed within the space enclosed by the nut box and the sheet metal of the body-in-white means that before the bolts are driven in, the nut plate may adhere to the sheet metal or nut box of the body-in-white. During the electrophoresis process of the body-in-white, electrophoretic paint will also flow through the nut box. If the nut plate adheres to the sheet metal or nut box during the electrophoresis process, after the electrophoresis is completed and the electrophoretic paint is baked, the nut plate will stick to the sheet metal or nut box. The current method is to manually knock it apart, but this will cause a large area of ​​the electrophoretic layer to peel off from the adhesive surface of the nut plate. Although the nut plate is located inside the B-pillar and is not exposed to the outside, so it does not affect the aesthetics, it still has a certain impact on corrosion resistance.

[0029] like Figure 1 and Figure 2 As shown, this embodiment provides a nut plate 10, including a base plate 11. The base plate 11 has two opposing plate surfaces. Two nut portions 12 are provided on one of the plate surfaces 111 of the base plate 11. The two nut portions 12 are arranged along the length direction of the base plate 11 and are spaced apart. The nut portion 12 is, in a conventional sense, a nut on the nut plate 10 through which a bolt passes, and can be a nut welded to the base plate 11 to form the nut portion 12. A threaded hole 121 is provided on the nut portion 12, and the axis of the threaded hole 121 is perpendicular to the plate surface 111 of the base plate 11. A through hole coaxial with the threaded hole 121 of the nut portion 12 is provided on the base plate 11 for the bolt to pass through. Support portions 13 are provided on both opposing plate surfaces 111 of the base plate 11. The support portions 13 protrude from the plate surface 111 of the base plate 11 in a direction away from the plate surface 111, so that the base plate 11 is not tightly fitted with the sheet metal of the vehicle body or the nut box.

[0030] The nut plate 10 provided in this embodiment, by providing support portions 13 on both surfaces 111 of the substrate 11, ensures that there is a gap between the substrate 11 and the sheet metal or nut box during the electrophoresis process, allowing the electrophoretic paint to flow through the gap between the substrate 11 and the sheet metal or nut box. During the subsequent baking process, due to the gap between the nut plate 10 and the sheet metal or nut box, the nut plate 10 will not adhere to the sheet metal or nut box. The support portion 13 can be configured as a cone, frustum, hemisphere, etc., with the tip or small end of the support portion 13 facing the sheet metal or nut box to reduce the contact area between the support portion 13 and the sheet metal or nut box. After electrophoresis is completed and baking is performed, the support portion 13 can also be easily detached from the sheet metal or nut box without causing large-area peeling of the electrophoretic layer.

[0031] Furthermore, the substrate 11 is generally rectangular in shape, and at least one pair of support portions 13 are provided on the two surfaces 111 of the support substrate 11. The two support portions 13 in the pair are on the same diagonal line of the substrate 11, and the support portions 13 are close to the edge of the substrate 11. That is to say, the support portions 13 are located at at least two diagonals of the substrate 11.

[0032] When there is a pair of support parts 13, each of the two surfaces 111 of the substrate 11 is provided with a support part 13, and the two support parts 13 are located on the same diagonal line of the substrate 11. The two support parts 13 can ensure that the substrate 11 will not adhere to the sheet metal or nut box over a large area. Even if the two support parts 13 do not provide stable support for the nut plate 10, and the nut plate 10 tilts and contacts the sheet metal or nut box, this contact will only be the edge of the nut plate 10 contacting the sheet metal or nut box. The contact between the nut plate 10 and the sheet metal or nut box will only be a linear adhesion, and will not cause the problem of large-area adhesion between the nut plate 10 and the sheet metal or nut box, making it difficult to peel off. Setting two support parts 13 can minimize the number of support parts 13, reduce costs and production difficulty.

[0033] When there are two pairs of support portions 13, the four support portions 13 can be located at the four apex corners of the substrate 11. These four support portions 13 can be located on one surface 111 of the substrate 11 or distributed on two surfaces 111. This provides stable support for the substrate 11 and completely prevents the substrate 11 from adhering to the sheet metal or nut box. When there are multiple pairs of support portions 13, the multiple pairs of support portions 13 are all arranged on the two diagonals of the substrate 11. The number of support portions 13 is preferably one or two pairs. The support portions 13 may not be distributed on the diagonals of the substrate 11. For example, multiple support portions 13 are provided on both surfaces 111 of the substrate 11. The multiple support portions 13 are arranged sequentially along one edge of the surface 111 of the substrate 11, or sequentially along two opposite edges of the surface 111 of the substrate 11.

[0034] It should be understood that, to suit actual needs, the cross-sectional shape of the substrate 11 may not be a standard rectangle. For example, the four corners of the substrate 11 may be smooth arcs to avoid accidentally injuring workers, or the substrate 11 may be an irregular strip shape with a long side and a short side. The support portion 13 is located at two diagonally opposite vertices on the substrate 11. In embodiments with more than four support portions, multiple support portions may be provided at each vertex. These should all fall within the scope of this embodiment.

[0035] In some embodiments, the support portion 13 is integrally stamped onto the substrate 11. Specifically, stamping is performed on one surface 111 of the substrate 11, causing that surface 111 to be recessed inwards, while the other surface 111 of the substrate 11 convexes outwards as the substrate 11 deforms. In this manner, the substrate 11 and the support portion 13 are essentially an integral structure, which can be formed during the production of the substrate 11 using a stamping process.

[0036] In some embodiments, the substrate 11 has a first positioning hole 14 with an axis perpendicular to the plate surface 111 of the substrate 11. When a bolt is driven into the nut portion 12, since the nut plate 10 can move appropriately within the nut box, it is necessary to align the threaded hole 121 of the nut portion 12 of the nut plate 10 with the hole in the sheet metal of the vehicle body. At this time, a hole coaxial with the first positioning hole 14 can be opened on the sheet metal. By inserting a pin into the first positioning hole 14 and the corresponding hole on the sheet metal, the nut plate 10 is kept in the installation position with the sheet metal of the vehicle body, thereby aligning the threaded hole 121 of the nut portion 12 of the nut plate 10 with the hole on the sheet metal, which facilitates the driving of bolts into the nut portion 12 of the nut plate 10. When there are multiple nut portions 12, such as two in this embodiment, the first positioning hole 14 is located between two adjacent nut portions 12.

[0037] In summary, the nut plate 10 provided in this embodiment, by providing a support portion 13 on the plate surface 111, enables the nut plate 10 to maintain a distance from the sheet metal or nut box, preventing large-area adhesion between the nut plate 10 and the sheet metal or nut box after electrophoresis on the body-in-white. Furthermore, the support portion 13 is formed on the substrate 11 through a stamping process, meaning it can be formed during the production of the nut plate 10 without requiring additional steps. Moreover, the support portion 13 is located at an obliquely opposite vertex on the substrate 11, reducing the number of support portions 13 required.

[0038] like Figures 3 to 5As shown, this embodiment also provides a door lock mounting structure, including a nut box 20, a body sheet metal 30, and a nut plate 10 as described above. The body sheet metal 30 can be a sheet metal for mounting the door lock at the B-pillar of the vehicle body, or a sheet metal for mounting the trunk door lock at the trunk door of the vehicle body. The nut box 20 is connected to the body sheet metal 30 and encloses it to form an accommodating space 40. The thickness of the nut plate 10 is less than the distance between the body sheet metal 30 and the nut box 20, and the area of ​​the nut plate 10 is less than the cross-sectional area of ​​the accommodating space 40 formed by the nut box 20 and the sheet metal. Specifically, the thickness of the nut plate 10 is 2mm, the distance between the nut box 20 and the body sheet metal 30 is 3mm, that is, the effective range of motion of the nut plate 10 is 1mm, and the thickness of the support part 13 is 0.2mm, so that the nut plate 10 is movably installed in the accommodating space 40. The nut box 20 has two through holes 211 for the nut part 12 to pass through. The nut part 12 of the nut plate 10 passes through the through holes 211 of the nut box 20 and is located outside the nut box 20. The body sheet metal 30 has a mounting hole 31 coaxial with the through holes 211 of the nut box 20 (see Figure 5 The two surfaces 111 of the nut plate 10 face the body sheet metal 30 and the nut box 20 respectively.

[0039] In the door latch mounting structure provided in this embodiment, the nut plate 10 is movably mounted between the body sheet metal 30 and the nut box 20. This allows the nut plate 10 to be slightly adjusted within the nut box 20 when the bolt is driven in, thereby aligning the threaded hole 121 of the nut portion 12 of the nut plate 10 with the mounting hole 31 on the body sheet metal 30. When the bolt is driven in, the bolt passes through the mounting hole 31 of the body sheet metal 30 and the threaded hole 121 of the nut portion 12 in sequence, thus fixing the nut plate 10 to the body. The door latch structure is then fixed to the body sheet metal 30 by the bolts.

[0040] Specifically, such as Figures 3 to 6As shown, the nut box 20 includes a main body 21 and connecting parts connected to the main body 21. The main body 21 is generally rectangular, and there are three connecting parts: a first connecting part 22, a second connecting part 23, and a third connecting part 24. The first connecting part 22 and the second connecting part 23 are connected to the edges of opposite sides of the main body 21 and extend obliquely toward the direction close to the body sheet metal 30. The third connecting part 24 is connected to the edge of one of the other two opposite sides of the main body 21 and extends toward the direction close to the body sheet metal 30. The first connecting part 22, the second connecting part 23, and the third connecting part 24 extend along the edge of the main body 21 toward the direction close to the body sheet metal 30 to form an accommodating space 40 between the body sheet metal 30 and the main body 21. Furthermore, the ends of the first connecting part 22, the second connecting part 23, and the third connecting part 24 that are connected to the body sheet metal 30 also have welding parts 25 extending in a direction parallel to the body sheet metal 30. The welding parts 25 are attached to the surface of the body sheet metal 30. The nut box 20 is welded to the body sheet metal 30 through the welding parts 25 connected to the first connecting part 22, the second connecting part 23, and the third connecting part 24, thereby fixing the nut box 20 to the body sheet metal 30. In addition, the main body 21 is also provided with a through hole 211 for the nut part 12 that is adapted to the nut plate 10.

[0041] Furthermore, such as Figure 3 and Figure 4 As shown, the first connecting portion 22, the second connecting portion 23, and the third connecting portion 24 are spaced apart to form a drainage channel 50 communicating with the receiving space 40 between the three connecting portions. During electrophoresis, the electrophoretic paint can flow into and out of the receiving space 40 through the drainage channel 50, avoiding the problem of electrophoretic paint flowing into the nut box 20 through the through hole 211 and not being able to flow out, thus preventing the electrophoretic paint from accumulating in the nut box 20.

[0042] Furthermore, such as Figure 3 , Figure 5 and Figure 6As shown, there are two third connecting parts 24, which are connected to the same side of the main body 21. There is a gap between the two third connecting parts 24. A positioning part 26 extends outward from the main body 21 between the two third connecting parts 24, moving away from the main body 21. The positioning part 26 is flush with the main body 21. The edge of the positioning part 26 on the side away from the main body 21 is recessed inward towards the main body 21, forming a positioning groove 261. Correspondingly, a second positioning hole 32 is provided on the body sheet metal 30, and the positioning groove 261 of the positioning part 26 is aligned with the second positioning hole 32. Before welding the nut box 20 to the body sheet metal 30 via the welding part 25, the relative positions of the nut box 20 and the body sheet metal 30 need to be adjusted to ensure that the nut box 20 is welded to the preset position. At this time, a tooling with two parallel positioning pins is used to position the nut box 20 and the body sheet metal 30. The body part 21 of the nut box 20 has a third positioning hole 212 that is coaxial with the first positioning hole 14 of the nut plate 10. The body sheet metal 30 also has a fourth positioning hole 33 that is coaxial with the first positioning hole 14. One of the positioning pins of the tooling is inserted into the fourth positioning hole 33 of the nut box 20, the first positioning hole 14 of the nut plate 10, and the third positioning hole 212 of the body sheet metal 30. The other positioning pin of the tooling is inserted into the second positioning hole 32 of the body sheet metal 30 and abuts against the positioning groove 261 of the positioning part 26. The two positioning pins ensure that the welding position of the nut box 20 on the body sheet metal 30 is accurate.

[0043] To accommodate nut boxes 20 of different sizes, the second positioning hole 32 is an oblong hole, with the length direction of the oblong hole aligned with the concave direction of the positioning groove 261. When adjusting the position of the nut box 20 on the body sheet metal 30, one of the positioning pins of the tooling is inserted into the third positioning hole 212 of the nut box 20, the first positioning hole 14 of the nut plate 10, and the fourth positioning hole 33 of the body sheet metal 30. The other positioning pin of the tooling is inserted into the second positioning hole 32 of the body sheet metal 30 and abuts against the positioning groove 261 of the positioning part 26. Since the second positioning hole 32 is an oblong hole, the position of the positioning pin in the second positioning hole 32 can be adaptively adjusted according to the size of the nut box 20, thereby adapting to the size of the nut box 20.

[0044] At the same time, such as Figure 1 , Figure 2 and Figure 6As shown, the nut plate 10 has two opposing sides. The center of one side of the nut plate 10 is recessed inwards towards the other side, forming an arc-shaped recess 15. The edge of the nut box 20 extends towards the body sheet metal 30 with an abutment portion 27. The shape of the abutment portion 27 matches the shape of the recess 15, and the abutment portion 27 is also arc-shaped. When the nut box 20 and the body sheet metal 30 are assembled together, the abutment portion 27 of the nut box 20 corresponds to the recess 15 of the nut plate 10, and the abutment portion 27 is used to limit the nut plate 10. This reduces the range of motion of the nut plate 10 within the nut box 20. When bolts are driven into the nut portion 12 of the nut plate 10, it is convenient to adjust the alignment of the threaded hole 121 of the nut portion 12 with the mounting hole 31 of the body sheet metal 30.

[0045] In summary, the door lock mounting structure provided in this embodiment can prevent the nut plate 10 from being adhered to the body sheet metal 30 or nut box 20 over a large area after the body white is electrophoretically coated, and the nut box 20 and body sheet metal 30 are easy to assemble.

[0046] This embodiment also provides an automobile, including the nut plate 10 as described above.

[0047] This embodiment also provides a car, including the door latch mounting structure described above.

[0048] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
