Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a movable nut assembly and a vehicle. Background Technology

[0002] Some automotive parts have excessively long dimensional chains. Traditional fasteners, such as nuts and bolts, often need to be fixed at specific angles and positions because their positions are not adjustable. This prevents the fasteners from moving freely and effectively absorbing errors, resulting in excessively high cumulative errors. Consequently, parts at locations with excessive errors may not be able to be effectively fastened. Utility Model Content

[0003] In view of this, the present invention provides a movable nut assembly and a vehicle to solve the problem that traditional fasteners cannot effectively absorb errors, resulting in excessive cumulative errors.

[0004] In a first aspect, this utility model provides a movable nut assembly, comprising:

[0005] The nut component includes a nut post and a movable plate disposed at one axial end of the nut post. The nut post has a threaded hole, and the movable plate has a through hole corresponding to the threaded hole.

[0006] The limiting component includes a plate body, an X-direction limiting part, and a Y-direction limiting part. The X-direction limiting part is disposed at both ends of the plate body along the X direction, and the Y-direction limiting part is disposed at both ends of the plate body along the Y direction.

[0007] The movable plate is movably positioned between the X-direction limiting parts at both ends, and the movable plate is also movably positioned between the Y-direction limiting parts at both ends;

[0008] The plate body is formed by a through hole, and the threaded hole is projected into the through hole along the Z direction. The Z, X and Y directions are perpendicular to each other.

[0009] Beneficial effects: The movable nut assembly provided in this embodiment of the invention can effectively absorb the cumulative errors caused by the components and assembly by moving the nut when the components to be fastened are pre-tightened. Simultaneously, it limits the amount of movement of the nut in the X and Y directions, ensuring that the nut moves within the required space, thus adapting to different installation positions and angles. Furthermore, the nut, in conjunction with the limiting component, provides sufficient anti-rotation strength during tightening, ensuring that the parts are properly fastened.

[0010] In one optional embodiment, the limiting member further includes a Z-direction limiting part, and the movable plate is movably disposed between the Z-direction limiting part and the plate body.

[0011] Beneficial effects: By further forming a Z-axis limiting part, the movement of the movable plate in the Z-axis is also effectively restricted, ensuring its stability in three-dimensional space. At the same time, the nut and the limiting part form a combination, ensuring that the movable plate is always within the space enclosed by the limiting part, preventing it from falling off, thus facilitating the operator's handling and improving assembly efficiency and accuracy.

[0012] In one alternative embodiment, the Z-direction limiting part is connected to the Y-direction limiting part.

[0013] In one alternative embodiment, the Z-direction limiting portion and the Y-direction limiting portion are connected via a bending portion, which is constructed in an arc shape and is suitable for the Z-direction limiting portion to bend relative to the Y-direction limiting portion by an angle β, wherein 0° < β < 360°.

[0014] Beneficial effects: The bending section enhances structural flexibility, allowing the Z-axis limiting section to adjust its angle according to actual needs, further optimizing the spatial adaptability of the nut component. By adding the Z-axis limiting section, the limiting component can easily surround the nut component to form a movable nut assembly, facilitating the fixing of the nut component within a specific area.

[0015] In one optional embodiment, the Z-direction limiting portion includes a plurality of portions spaced apart along the X-direction, and at least two adjacent Z-direction limiting portions are connected by a connecting rib.

[0016] Beneficial effects: On the one hand, the connecting ribs enhance the overall rigidity of the Z-direction limiting part. On the other hand, the presence of the connecting ribs effectively prevents the deformation of the Z-direction limiting part, ensuring its stability and reliability in long-term use. Furthermore, the presence of the connecting ribs also facilitates the Z-direction limiting of the movable plate, preventing the nut from coming off.

[0017] In one alternative embodiment, the movable nut assembly further includes a welded portion connected to the plate body, wherein the side of the welded portion opposite to the nut is adapted to form a raised weld point.

[0018] Beneficial effects: By forming a weld joint, the movable nut assembly can be easily welded to a predetermined location, such as a sheet metal part that provides fastening for components. This ensures that the movable nut assembly remains firmly connected under vibration or impact conditions, improving the overall structure's durability and safety. The raised weld point design enhances weld strength and avoids the risk of detachment due to weak welds.

[0019] In one alternative implementation, the limiting member is integrally formed.

[0020] Beneficial effects: The limiting component in this embodiment is integrally molded, and through precision punching and bending processes, it ensures a compact structure and high strength, avoiding the complexity and potential failure points of assembling multiple parts, and further improving the reliability and service life of the overall structure.

[0021] In one alternative embodiment, the nut post is located on one side of the plate body and has a guide portion formed circumferentially around the threaded hole.

[0022] Beneficial effects: By forming a guide section, the bolt can be precisely aligned when inserted into the threaded hole, reducing installation errors and improving assembly efficiency. Furthermore, when the bolt position is difficult to adjust, the beveled design of the guide section can automatically adjust the nut's position to alignment, ensuring smooth bolt insertion and avoiding installation difficulties caused by misalignment.

[0023] In one optional embodiment, both the X-direction limiting part and the Y-direction limiting part are disposed on one side of the plate body along the Z direction;

[0024] The X-direction limiting part is set perpendicular to the plate body;

[0025] The Y-direction limiting part is set perpendicular to the plate body;

[0026] The Z-direction limiting part and the Y-direction limiting part are parallel to each other along the Y direction and are spaced apart.

[0027] Beneficial effects: By setting both the X-direction limiting part and the Y-direction limiting part on one side of the plate body along the Z direction, the limiting effect on one side is guaranteed, which simplifies the structural design, reduces the assembly steps, improves the convenience and efficiency of the overall assembly, and at the same time ensures the synergistic effect of the limiting functions in each direction, thereby enhancing the stability and deformation resistance of the overall structure.

[0028] Secondly, this utility model also provides a vehicle, comprising:

[0029] Vehicle body;

[0030] And the aforementioned movable nut assembly welded to the vehicle body;

[0031] It also includes: bolts, which are suitable for threaded connection with nuts to lock and secure the nuts to the limiting members.

[0032] Beneficial effects: By connecting the bolt and nut with threads, it is possible to ensure that the nut and the limiting part have a certain amount of movement, so that the bolt and nut can move flexibly relative to the limiting part when connected. It can effectively absorb the cumulative error caused by parts and assembly, adapt to different installation positions and angles, and also achieve locking and fixing of the nut and the limiting part.

[0046] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0047] The following is combined Figures 1 to 6 The following describes embodiments of the present invention.

[0048] According to an embodiment of the present invention, in one aspect, a movable nut assembly is provided, comprising:

[0049] Nut component 1 includes a nut post 11 and a movable plate 12 disposed at one axial end of the nut post 11. The nut post 11 has a threaded hole 13, and the movable plate 12 has a through hole 15 corresponding to the threaded hole 13.

[0050] The limiting member 2 includes a plate body 21, an X-direction limiting part 22 and a Y-direction limiting part 26. The X-direction limiting part 22 is disposed at both ends of the plate body 21 along the X direction, and the Y-direction limiting part 26 is disposed at both ends of the plate body 21 along the Y direction.

[0051] The movable plate 12 is movably disposed between the X-direction limiting parts 22 at both ends, and the movable plate 12 is movably disposed between the Y-direction limiting parts 26 at both ends;

[0052] The plate body 21 is formed through a through hole 24, and the threaded hole 13 is projected into the through hole 24 along the Z direction, wherein the Z direction, X direction and Y direction are perpendicular to each other.

[0053] In this embodiment, the nut column 11 and the movable plate 12 disposed at one end of the axial direction of the nut column 11 are an integral structure, so that the nut column 11 and the movable plate 12 move synchronously. When the movable plate 12 moves along the X, Y or Z direction, the nut column 11 also moves accordingly. Thus, the nut column 11 can be flexibly positioned in three-dimensional space by adjusting the movable plate 12, so as to achieve precise adjustment.

[0054] The limiting member 2 includes a plate body 21. In this embodiment, the plane where the plate body 21 is located is defined to be parallel to the plane jointly defined by the X and Y directions, that is, the plane where the plate body 21 is located is perpendicular to the Z direction.

[0055] The movable plate 12 is located on one side of the plate body 21 along the Z direction. The plate body 21 can be used to limit the movable plate 12 on one side along the Z direction. The plate body 21 plays a supporting and guiding role for the movable plate 12, ensuring its stability and accuracy when moving in the Z direction.

[0056] The limiting member 2 also includes an X-direction limiting portion 22 and a Y-direction limiting portion 26, both of which extend from the plate body 21. Specifically, both the X-direction limiting portion 22 and the Y-direction limiting portion 26 extend toward the side of the plate body 21 where the nut member 1 is located. In this embodiment, the X-direction limiting portion 22 is formed by folding the plate body 21 by 90°, and the Y-direction limiting portion 26 is formed by folding the plate body 21 by 90°.

[0057] Combination Figure 2 As shown, both ends of the plate body 21 along the X direction are provided with X-direction limiting parts 22, and both ends of the plate body 21 along the Y direction are provided with Y-direction limiting parts 26. Furthermore, the movable plate 12 is movably disposed between the X-direction limiting parts 22 at both ends and between the Y-direction limiting parts 26 at both ends, thereby ensuring that the movable plate 12 is effectively restricted when moving along the X or Y direction, preventing excessive displacement. Through the constraint of the limiting members 2, the movement range of the movable plate 12 and the nut column 11 is controlled, avoiding excessive displacement.

[0058] In this embodiment, the nut post 11 has a threaded hole 13, which can be used to engage with a bolt to fix or adjust the nut post 11. When the bolt is inserted into the threaded hole 13, it needs to pass through the plate body 21. By making the plate body 21 pass through to form a through hole 24, and the threaded hole 13 is projected into the through hole 24 along the Z direction, the plate body 21 is avoided from obstructing the installation of the bolt, and the bolt can move flexibly within the through hole 24, ensuring that the nut post 11 is accurately positioned in three-dimensional space.

[0059] In this embodiment, the diameter of the through hole 24 is larger than the diameter of the threaded hole 13, ensuring that the bolt can be smoothly inserted and leaving enough adjustment space, thereby improving the ease of installation and adjustment accuracy.

[0060] The movable nut assembly provided in this embodiment of the invention can effectively absorb the cumulative errors caused by the components and assembly by moving the nut when the components to be fastened are pre-tightened. Simultaneously, it restricts the amount of movement of the nut in the X and Y directions, ensuring that the nut moves within the required space, thus adapting to different installation positions and angles. Furthermore, the nut 1 cooperates with the limiting member 2 to provide sufficient anti-rotation strength during tightening, ensuring that the parts are properly tightened.

[0061] In some embodiments, the limiting member 2 further includes a Z-direction limiting part 25, and the movable plate 12 is movably disposed between the Z-direction limiting part 25 and the plate body 21 along the Z direction.

[0062] By further forming the Z-direction limiting part 25, the movement of the movable plate 12 in the Z-direction is also effectively restricted, ensuring its stability in three-dimensional space. At the same time, the nut part 1 and the limiting part 2 form a combination, so that the movable plate 12 is always within the space enclosed by the limiting part 2, preventing it from falling off, thereby facilitating the operator to handle it and improving assembly efficiency and accuracy.

[0063] The limiting component 2 can restrict the movement of the nut component 1 in the X, Y and Z directions, ensuring that the nut component can move within the required space, thereby adapting to different installation positions and angles.

[0064] In some embodiments, the Z-direction limiting portion 25 is connected to the Y-direction limiting portion 26.

[0065] In some embodiments, the Z-direction limiting portion 25 and the Y-direction limiting portion 26 are connected via a bending portion 27, which is constructed in an arc shape and is adapted to allow the Z-direction limiting portion 25 to bend relative to the Y-direction limiting portion 26 by an angle β, wherein 0° < β < 360°.

[0066] The bending portion 27 enhances structural flexibility, allowing the Z-direction limiting portion 25 to adjust its angle according to actual needs, further optimizing the spatial adaptability of the nut component 1. In this embodiment, the Y-direction limiting portion 26 is formed by folding the plate body 21 by 90°, and through the further folding of the bending portion 27, the Z-direction limiting portion 25 forms a 180° flange relative to the plate body 21.

[0067] By adding the Z-direction limiting part 25, the limiting part 2 can easily surround the nut part 1 to form a movable nut assembly, which makes it easy to fix the nut part 1 in a specific area.

[0068] In some embodiments, the limiting member 2 includes a plurality of Z-direction limiting portions 25 spaced apart along the X direction, and a connecting rib 28 is connected between at least two adjacent Z-direction limiting portions 25.

[0069] The connecting rib 28 enhances the overall rigidity of the Z-direction limiting part 25. On the other hand, the presence of the connecting rib 28 effectively prevents the deformation of the Z-direction limiting part 25, ensuring its stability and reliability in long-term use. Furthermore, the presence of the connecting rib 28 also facilitates the Z-direction limiting of the movable plate 12, preventing the nut part 1 from coming off.

[0070] In some embodiments, the movable nut assembly further includes a welding portion 23, which is connected to the plate body 21, and the side of the welding portion 23 facing away from the nut 1 is adapted to form a protruding weld point 231.

[0071] By forming the weld portion 23, the movable nut assembly can be easily welded to a predetermined location, such as a sheet metal part that provides fastening for components. This ensures that the movable nut assembly remains firmly connected under vibration or impact conditions, improving the overall structure's durability and safety. The design of the projection weld point 231 enhances the weld strength and avoids the risk of detachment due to weak welds.

[0072] In this embodiment, the limiting member 2 can be made from a square flat sheet metal through a punching and bending process. The welding part 23 can be the sheet metal remaining after punching and folding the Y-direction limiting part 26, the bending part 27 and the Z-direction limiting part 25, thereby maximizing the use of materials, making the material utilization rate more than 95%, and reducing cost waste.

[0073] In some embodiments, the limiting member 2 is integrally formed.

[0074] In this embodiment, the limiting component 2 is integrally formed. Through precision punching and bending processes, it ensures a compact structure and high strength, avoiding the complexity and potential failure points of assembling multiple components, and further improving the reliability and service life of the overall structure.

[0075] In some embodiments, combined with Figure 5 As shown, the nut post 11 is located on the side near the plate body 21, and a guide portion 14 is formed around the threaded hole 13 in the circumferential direction.

[0076] By forming a guide section, the bolt can be precisely aligned when it enters the threaded hole 13, reducing installation errors and improving assembly efficiency. Furthermore, when the position of the bolt is inconvenient to adjust, the inclined surface design of the guide section 14 can also automatically adjust the position of the nut 1 to the aligned state, ensuring that the bolt can be screwed in smoothly and avoiding installation difficulties caused by misalignment.

[0077] In some embodiments, the X-direction limiting part 22 and the Y-direction limiting part 26 are both disposed on one side of the plate body 21 along the Z direction;

[0078] The X-direction limiting part 22 is arranged perpendicularly to the plate body 21;

[0079] The Y-direction limiting part 26 is arranged perpendicularly to the plate body 21;

[0080] The Z-direction limiting part 25 and the Y-direction limiting part 26 are arranged parallel to each other along the Y direction and spaced apart.

[0081] The X-direction limiting part 22 and the Y-direction limiting part 26 are both set on one side of the plate body 21 along the Z direction, thereby ensuring the limiting effect on one side, simplifying the structural design, reducing assembly steps, improving the convenience and efficiency of overall assembly, and ensuring the synergistic effect of the limiting functions in each direction, thereby enhancing the stability and deformation resistance of the overall structure.

[0082] Furthermore, the Z-direction limiting part 25 and the Y-direction limiting part 26 are arranged parallel to each other along the Y direction and spaced apart, which further optimizes the spatial layout, avoids the interference between the limiting parts in different directions, ensures that each limiting part can act independently and effectively in three-dimensional space, facilitates the control of the amount of movement in each direction, and thus simultaneously restricts the amount of movement of the nut part 1 in the X, Y and Z directions.

[0083] The movable nut assembly in this embodiment is expandable, and the dimensions of the limiting member 2 and the nut member 1 can be matched according to the required amount of movement.

[0084] According to an embodiment of the present invention, another aspect provides a vehicle, comprising:

[0085] Such as the movable nut assembly described above;

[0086] The limiting member 2 of the movable nut assembly is suitable for welding connection with the vehicle body;

[0087] Components to be fixed;

[0088] Bolts are used to insert into the part to be fixed and to connect with the nut 1 through the threaded hole 13 to lock and fix the part to be fixed to the vehicle body.

[0089] By connecting the bolt and nut 1 with threads, it is possible to ensure that the nut 1 and the limiting part 2 have a certain amount of movement, so that the bolt and nut 1 can move flexibly relative to the limiting part 2 when connected. This can effectively absorb the cumulative errors caused by parts and assembly, adapt to different installation positions and angles, and also achieve the locking and fixing of the nut 1 and the limiting part 2, thereby locking and fixing the part to be fixed to the vehicle body.

[0090] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
