Description

Technical Field

[0001] The present disclosure relates to a vehicle component fastening structure with adjustable step difference. Background Art

[0002] Generally, for a finished product such as a vehicle that is composed of a plurality of parts, bolts and nuts are usually used to fasten the parts.

[0003] In order to fix a component to a vehicle body using bolts and nuts, after setting the component in a state where a nut is fixed to the back side of the vehicle body by welding, a bolt is tightened to the nut on the other side of the nut, whereby the component can be firmly fastened to the vehicle body.

[0004] However, in the case of conventionally fastening a component to a vehicle body using bolts and nuts, it may be impossible to cope with a situation where a gap needs to be provided between the vehicle body and the component in order to adjust the accuracy of the vehicle body or the component.

[0005] That is, when fastening a component to a vehicle body, it is impossible to adjust the above-mentioned fastening by bolts and nuts. In particular, when welding a nut to one side of the vehicle body, it is difficult to adjust the step or gap between the component and another component or between the component and the vehicle body.

[0006] If such a step or gap cannot be adjusted, workability is degraded due to factors such as replacement of parts and change of vehicle body shape.

[0007] Meanwhile, if an excessive gap or step occurs in the bumper mating part due to accumulation of tolerances of the lamp and fender when assembling the lamp and fender, marketability decreases and it becomes difficult to finely change the illumination angle of the light source after the lamp is assembled.

[0008] The above information disclosed in this Background section is only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.

Figure 2 2 is a cross-sectional view illustrating a vehicle component fastening structure with adjustable step according to an embodiment of the present disclosure.

[0038] Reference Figure 1 and Figure 2 According to an embodiment of the present disclosure, a vehicle component fastening structure with adjustable step includes: a weld nut 100, fixed to a vehicle floor; an inner bolt 200, arranged above the weld nut 100 and inserted into and fixed inside the weld nut 100; and an assembly bolt 300, inserted through the inner bolt 200 and fastened to one end of the weld nut 100, wherein the inner bolt 200 moves in a height direction to adjust the step.

[0039] The weld nut 100 can be fixed to the vehicle floor. Preferably, the weld nut 100 is used to mount a functional component to a vehicle body, and can be inserted through a mounting member formed on the vehicle floor and then mounted to the vehicle floor by welding.

[0040] The weld nut 100 may include a weld nut stopper 110 exposed to an upper surface of a vehicle floor, and a weld nut fastening portion 120 formed at an end of the weld nut stopper 110 .

[0041] The weld nut flange 110 may have a disc shape and have a hole for insertion of the inner bolt 200. A lower surface of the weld nut flange 110 may be welded and attached to an upper surface of a vehicle floor.

[0042] The weld nut fastening portion 120 may be formed extending from an end portion of the weld nut flange 110. In a state where the weld nut 100 is fixed to the vehicle floor, the weld nut fastening portion 120 may be located under the vehicle floor.

[0043] The inner bolt 200 may be disposed above the weld nut 100 and inserted and fixed inside the weld nut 100. The inner bolt 200 may include an inner bolt flange 210 formed above the weld nut flange 110 and an inner bolt fastening portion 220 formed at an end of the inner bolt flange 210.

[0044] The lower surface of the inner bolt flange 210 may be adjacent to the weld nut flange 110, and components to be assembled may meet at the upper surface of the inner bolt flange 210. The inner bolt fastening portion 220 may be formed at an end of the inner bolt flange 210 and inserted into the weld nut fastening portion 120.

[0045] The weld nut fastening part 120 and the inner bolt fastening part 220 can be coupled to each other by the fastening force of threads respectively formed on the weld nut fastening part 120 and the inner bolt fastening part 220. The inner bolt fastening part 220 can be inserted into the weld nut fastening part 120 while being rotated to be fixed to the weld nut fastening part 120.

[0046] According to an embodiment, the weld nut 100 and the inner bolt 200 may be made of polyamide (PA), an engineering plastic material. Preferably, the weld nut 100 and the inner bolt 200 may be made of PA66. Therefore, when the weld nut 100 and the inner bolt 200 are reassembled with each other, deformation can be prevented and rigidity can be ensured.

[0047] The weld nut 100 and the inner bolt 200 may also be made of high-tech plastics such as glass fiber reinforced plastic or carbon fiber reinforced plastic to improve robustness even in a small size. Examples of high-tech plastics include, but are not limited to, polyacetal resin (POM), polybutylene terephthalate (PBT), mPPO, and polycarbonate (PC).

[0048] The assembling bolt 300 may be inserted through the inner bolt 200 and fastened to one end of the weld nut 100. The assembling bolt 300 may be fastened to the inner bolt 200 to secure the component to the vehicle body.

[0049] In an embodiment, after the weld nut 100 and the inner bolt 200 are assembled with each other, the weld nut 100 can be fixed to the vehicle floor by welding and welding. Then, in a state where the component is placed on the inner bolt 200, the component can be fixed by tightening the assembly bolt 300 inside the inner bolt 200.

[0050] After the assembly is finally completed, if necessary, the gap or step of the components can be adjusted by moving the inner bolt 200 in the height direction. Preferably, since the components are connected on the upper part of the inner bolt 200, the position of the components can be finely adjusted by moving the inner bolt 200 in the height direction.

[0051] The vehicle component fastening structure with adjustable step according to the embodiment of the present disclosure can perform step adjustment according to the rotation amount of the inner bolt 200. The inner bolt 200 can move up and down in the height direction according to the rotation amount of the inner bolt 200.

[0052] The inner bolt flange 210 may have a polygonal shape to allow a tool to tighten or loosen the inner bolt 200. Therefore, various tools such as a wrench, an adjustable wrench, a socket wrench, and a ratchet wrench may be used to easily rotate the inner bolt 200. Preferably, the inner bolt flange 210 has a hexagonal shape so that the step of the component can be adjusted using a wrench.

[0053] Figure 3 1 is a perspective view illustrating an inner bolt of a vehicle component fastening structure with adjustable step according to an embodiment of the present disclosure.

[0054] Reference Figure 3 In the vehicle component fastening structure with adjustable step according to an embodiment of the present disclosure, the inner bolt fastening portion 220 includes a through hole 221 for inserting the assembly bolt 300. One end of the assembly bolt 300 inserted through the through hole 221 can be adjacent to the inner bolt flange 210, and the other end of the assembly bolt 300 can be fastened to the weld nut 100.

[0055] The inner bolt fastening portion 220 may include at least two slits 222 formed in a height direction and an inner protrusion 223 formed at one end of the through hole 221. The assembly bolt 300 may push the inner protrusion 223 outward while being inserted into the through hole 221, and the inner bolt fastening portion 220 may expand relative to the slits 222 to be pressed against the weld nut 100.

[0056] The inner bolt fastening portion 220 includes a through-hole 221 therein for inserting the assembly bolt 300. The through-hole 221 may not be threaded. The assembly bolt 300 may be inserted through the through-hole 221 of the inner bolt 200. One end of the assembly bolt 300 inserted through the inner bolt 200 may be adjacent to the inner bolt flange 210, and the other end of the assembly bolt 300 may be fastened to the weld nut 100.

[0057] After placing components on the inner bolt flange 210 with the weld nut 100 and the inner bolt 200 fastened to each other, the assembling bolt 300 may be inserted into the through hole 221 such that one end of the assembling bolt 300 is exposed above the components.

[0058] The inner bolt fastening portion 220 may include at least two slits 222 formed in the height direction. An inner protrusion 223 may be formed at one end of the through hole 221 to prevent the inner bolt 200 from loosening from the weld nut 100, so that the assembly bolt 300 presses the inner protrusion 223 outward while being inserted into the through hole 221.

[0059] In a state where the inner bolt 200 is coupled to the weld nut 100, the assembly bolt 300 can press the inner bolt 200 while being inserted into the through hole 221. Preferably, when the assembly bolt 300 is inserted to apply pressure to the inner protrusion 223, the inner bolt fastening portion 220 can expand relative to the slit 222 to be pressed against the weld nut 100. In this case, when two slits 222 are formed, the inner bolt fastening portion 220 can be separated into two parts and pressed against the weld nut 100, and when four slits 222 are formed, the inner bolt fastening portion 220 can be separated into four parts and pressed against the weld nut 100.

[0060] The inner bolt fastening portion 220 separated from the slit 222 may have multi-directional pressure points, and the present disclosure does not particularly limit the number of slits. In an embodiment, the inner protrusion 223 may protrude 0.25 mm in the width direction.

[0061] Therefore, the weld nut 100 can be first coupled with the inner bolt 200 through the threads therebetween, and the assembling bolt 300 can press the inner protrusion 223 to secondarily increase the fastening force between the weld nut 100 and the inner bolt 200, thereby preventing the inner bolt 200 from loosening.

[0062] Figure 4 1 is a diagram illustrating a state in which an assembly bolt is inserted into an inner bolt in the vehicle component fastening structure with adjustable step according to an embodiment of the present disclosure.

[0063] Reference Figure 4In the vehicle component fastening structure with adjustable step difference according to an embodiment of the present disclosure, the weld nut fastening portion 120 may include: a reverse thread 121 formed at the upper end of the weld nut fastening portion 120 for insertion of the internal bolt 200; and a forward thread 122 formed at the lower end of the weld nut fastening portion 120 for fastening with the assembly bolt 300.

[0064] After the other end of the assembling bolt 300 is fastened to the forward thread 122 , the inner bolt 200 may move in the height direction along the reverse thread 121 .

[0065] A reverse thread 121 may be formed at the upper end of the weld nut fastening portion 120 so that the inner bolt 200 is rotated and inserted through the reverse thread 121. The inner bolt fastening portion 220 may have a thread formed on an outer edge thereof and corresponding to the reverse thread 121 so that the weld nut 100 can be fastened to the inner bolt 200.

[0066] The weld nut fastening portion 120 may have a hole formed at a lower end thereof, and the hole may have an inner diameter corresponding to the outer diameter of the assembly bolt 300. The assembly bolt 300 may be inserted through the inner bolt 200 and fastened to the lower end of the weld nut fastening portion 120. Preferably, the assembly bolt 300 may have an assembly bolt thread 310 formed at the other end thereof, so that the assembly bolt 300 may be fixed by fastening the assembly bolt thread 310 with the forward thread 122 of the weld nut 100.

[0067] In the vehicle component fastening structure with adjustable step according to the embodiment of the present disclosure, after the other end of the assembling bolt 300 is fastened to the forward thread 122 , the inner bolt 200 may move in the height direction along the reverse thread 121 .

[0068] Preferably, after the assembly bolt threads 310 are coupled to the forward threads 122 for fastening, the gap or step between components can be adjusted by moving the inner bolt 200 in the height direction. When the operator rotates the inner bolt flange 210 using a tool such as a wrench, the gap or step between components such as a headlight that abut against the upper surface of the inner bolt 200 can be adjusted.

[0069] In summary, according to the vehicle component fastening structure with adjustable step difference in the embodiment of the present disclosure, since the external component is fixed by assembling the internal bolt 200 or the assembly bolt 300 to the weld nut 100 fixed to the vehicle body, the step difference of the external component can be adjusted only by adjusting the height of the internal bolt 200.

[0070] As apparent from the above description, the present disclosure can obtain the following effects through the configuration, combination, and relationship of the components described in the exemplary embodiments.

[0071] In the embodiment of the present disclosure, since the outer component is fixed by assembling the inner bolt or the assembly bolt to the weld nut fixed to the vehicle body, the step of the outer component can be adjusted only by adjusting the height of the inner bolt.

[0072] In addition, since the assembling bolt applies pressure to the inner protrusion formed on the inner bolt when the assembling bolt is inserted into the inner bolt, it is possible to prevent the inner bolt from being loosened from the weld nut.

[0073] The above detailed description is an illustration of the present disclosure. In addition, the above description is intended to illustrate and explain the preferred embodiments of the present disclosure, and the present disclosure can be used in various other combinations, modifications and environments.
