[0029] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations may, however, be implemented in many different forms and should not be construed as limited to the examples set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the scope of example implementations to those skilled in the art.
[0030] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the application. One skilled in the relevant art will recognize, however, that the application can be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures, devices, implementations, and operations have not been shown or described in detail to avoid obscuring aspects of the application.
[0031] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.
[0032] Combination Figures 1 to 8 As shown, this embodiment provides a nut mounting structure for mounting vehicle body parts.
[0033] like Figure 1 As shown, the nut mounting structure includes a nut mounting plate 10, which has a bolt through hole 101 for the bolt to pass through.
[0034] In this embodiment, the bolt through hole 101 penetrates the nut mounting plate 10. The radius of the bolt through hole 101 is 5mm larger than the inner diameter of the movable nut 30 to absorb errors and facilitate installation.
[0035] Combination Figures 1 to 4 As shown, the nut mounting structure also includes a nut limiting plate 20, which is detachably connected to the nut mounting plate 10. A cavity a is provided between the nut limiting plate 20 and the nut mounting plate 10. The nut limiting plate 20 is provided with a limiting hole 201, which connects the inside and outside of the cavity a. The limiting hole 201 is positioned opposite to the bolt through hole 101.
[0036] In this embodiment, the limiting hole 201 penetrates the nut limiting plate 20. The limiting hole 201 is coaxially arranged with the bolt through hole 101.
[0037] The nut mounting structure also includes a movable nut 30, which includes a limiting section 31 and a connecting section 32. The diameter of the limiting section 31 is smaller than that of the connecting section 32, the outer diameter of the connecting section 32 is larger than that of the bolt through hole 101, and the outer diameter of the connecting section 32 is larger than that of the limiting hole 201. The limiting section 31 passes through the limiting hole 201.
[0038] In this embodiment, the radius of the limiting hole 201 is 5mm larger than the outer diameter of the limiting section 31 of the movable nut 30, allowing the movable nut 30 to move on a plane parallel to the nut mounting plate 10, with a range of motion of 5mm on one side. This hole serves as both a through hole and a limiting hole 201.
[0039] In the utility model, since the limiting section 31 of the movable nut 30 is arranged in the limiting hole 201 of the nut limiting plate 20, the radial displacement of the movable nut 30 can be limited by the hole wall of the limiting hole 201; at the same time, the connecting section 32 is located in the cavity a between the nut mounting plate 10 and the nut limiting plate 20, the outer diameter of the connecting section 32 is greater than the diameter of the limiting hole 201 and greater than the diameter of the bolt through hole 101, thereby preventing the movable nut 30 from being displaced out of the cavity a along the axial direction. Therefore, when the nut mounting plate 10 is used, the nut mounting plate 10 or the nut limiting plate 20 is only needed to be fixed, and then the bolt is arranged in the movable nut 30 through the bolt through hole 101. If the movable nut 30 needs to be replaced, the nut mounting plate 10 and the nut limiting plate 20 are only needed to be disassembled, the cavity a is opened, and the movable nut 30 is taken out.
[0040] In summary, when the nut mounting structure is connected with the bolt, if the bolt is in the working condition that needs to be frequently assembled and disassembled, even if the movable nut 30 is slipped or damaged, the maintenance can be completed by replacing the movable nut 30, without replacing the part where the movable nut 30 is located, so that the maintenance cost is low and the maintenance period is short.
[0041] Further, the movable nut 30 comprises a first threaded hole section 301 and a second threaded hole section 302, the first threaded hole section 301 is closer to the bolt through hole 101 than the second threaded hole section 302; the diameter of the first threaded hole section 301 gradually decreases from the direction of the bolt through hole 101 to the direction of the second threaded hole section 302, thereby playing a guiding role when the bolt is installed in the movable nut 30.
[0042] Further, the height of the connecting section 32 in the cavity a is less than the height of the cavity a, thereby enabling the movable nut 30 to move in the direction perpendicular to the nut limiting plate 20.
[0043] For example, the height of the connecting section 32 in the cavity a is less than the height of the cavity a by 3mm.
[0044] It should be understood that the height in the cavity a refers to the spacing value between the nut mounting plate 10 and the nut limiting plate 20. The height of the connecting section 32 in the cavity a is less than the height of the cavity a, which means that the spacing between the top surface of the connecting section 32 facing the nut mounting plate 10 and the bottom surface of the connecting section 32 facing the nut limiting plate 20 is less than the height of the cavity a.
[0045] Further, the total length of the movable nut 30 is greater than the height of the cavity a and the thickness of the nut limiting plate 20, thereby enabling one end of the movable nut 30 to be located outside the cavity a, so as to fix the movable nut 30 and assemble the bolt.
[0046] Further, the diameter of the limiting hole 201 is greater than the outer diameter of the limiting section 31, so that the limiting section 31 of the movable nut 30 can pass out of the cavity a, so as to fix the movable nut 30 and assemble the bolt.
[0047] Further, the nut mounting plate 10 is in the shape of a "J" character, so that the middle arched plate surface of the nut mounting plate 10 forms the cavity a with the nut limiting plate 20, and the nut mounting plate 10 in the shape of a "J" character has better torsion resistance than the nut mounting plate 10 in the shape of a flat plate.
[0048] Further, the bolt through hole 101 is located in the middle region of the nut mounting plate 10, so that the nut mounting plate 10 is uniformly stressed after the bolt passes through the bolt through hole 101, and is not easy to open along the horizontal direction.
[0049] Further, the nut limiting plate 20 and the nut mounting plate 10 are detachably connected through the cooperation of the nut and the bolt, so as to detach the nut limiting plate 20 and the nut mounting plate 10 when the movable nut 30 is damaged, and then replace the movable nut 30.
[0050] Further, the nut is welded to the nut limiting plate 20, so as to realize bolt connection of the nut limiting plate 20 and the nut mounting plate 10.
[0051] In the present application, the projection nut 40 is changed to the movable nut 30, and the edge of the movable nut 30 has a 5mm movable space with the hole wall of the limiting hole 201 of the nut limiting plate 20, which can absorb the cumulative tolerance of the hole size tolerance of the assembly part hole of the movable nut 30, the welding tolerance, the assembly error, etc. during assembly; at the same time, the top of the movable nut 30 has a structure for guiding the bolt, which is easy to assemble the bolt. Therefore, when the part is in a working condition that needs to be frequently disassembled, the nut is easy to slip and collapse, and the application of this scheme can complete the maintenance by replacing the movable nut 30, without the need to replace the part where the nut is located, so that the maintenance cost is low and the maintenance period is short.
[0052] In addition, the nut limiting plate 20 may be various cross beams or longitudinal beams of a vehicle body and other structure forming a cavity in actual application, so that four projection bolts for disassembling the nut mounting plate 10 are projected on the various beams of the vehicle body, and the movable nut 30 through hole is opened thereon, and the nut limiting plate 20 does not need to be developed separately.
[0053] The present application also provides a vehicle, which comprises a vehicle body and the nut mounting structure.
