Description
BACKGROUND

Automotive components necessitate fastening techniques that prioritize simplicity in manufacturing and assembly while maintaining reliability and efficiency. One commonly utilized method involves the integration of stamped metal clips with fasteners.


Among these fasteners, metal spring-loaded components like U-nut fasteners (also recognized as J-nuts or speed nuts) often incorporate a retainer with an internally threaded bore. This design feature streamlines installation processes, eliminating the need for rear access to the fastening point. Widely utilized across automotive, aerospace, and electronic industries, these fasteners ensure robust and lasting attachment of components such as body panels, interior trim, and electrical enclosures. However, current spring-loaded fastening components are restricted in their compatibility with different fastener types, constrained by the specific thread type utilized in the internally threaded bore.


Therefore, despite existing advancements, a need exists for a multi-piece modular retainer that offers enhanced versatility and adaptability in fastening applications.


SUMMARY

The present disclosure relates generally to a multi-piece modular retainer assembly to form a connection between two components, such as vehicular components, substantially as illustrated by and described in connection with at least one of the figures, as set forth more completely in the claims. In some examples, the multi-piece modular retainer assembly comprises a modular, interchangeable multi-piece modular retainer assembly that allows a user to use various nuts in the same carrier.

FIGS. 1a and 1b illustrate, respectively, topside and underside isometric assembled views of a fastening system 100 having a modular retainer assembly 102 and fastener 108 in accordance with an aspect of this disclosure, while FIG. 1c illustrates a topside isometric assembly view of the fastening system 100. The modular retainer assembly 102 is configured to join the first component 104 and the second component 106. FIG. 1d illustrates a side elevation assembled view of the fastening system 100, while FIG. 1e illustrates a cross-sectional side view of the fastening system 100 of FIG. 1a taken along cut line A-A (FIG. 1a).


To facilitate attachment via the modular retainer assembly 102, each of the first component 104 and the second component 106 includes one or more engagement features. For example, the first component 104 is illustrated as having a first opening 114 formed therein and the second component 106 is illustrated as having a second opening 120 formed therein. In the illustrated example, each of the first opening 114 and the second opening 120 is circular and sized and shaped to receive a portion of the fastener 108.


The first opening 114 and the second opening 120 can be formed in the respective first component 104 or second component 106 during manufacturing thereof or added post-manufacture through a mechanical process (e.g., drilling, cutting, carving, etc.). After the first component 104 and the second component 106 are assembled, as illustrated, the second component 106 is covered at least partially by the first component 104.


The modular retainer assembly 102 is illustrated as a multi-component retainer assembly having a fastener 108 (e.g., an externally-threaded shaft, such as a bolt), a retainer clip 110 (e.g., a metal retainer clip, such as a U-nut fastener), and a nut insert 112 (e.g., an internally-threaded component, such as a nut). The retainer clip 110 serves to mechanically engage and couple with the first component 104 via the first opening 114, while the fastener 108 and the nut insert 112 serves to couple the first component (via the retainer clip 110) to the second component 106 (via its second opening 120).



FIGS. 2a through 2f illustrate various views of the example fastening system 100 of FIG. 1a with the first and second components 104, 106 omitted to better illustrate the components of the modular retainer assembly 102. Specifically, FIGS. 2a and 2b illustrate side elevation and underside isometric assembly views of the fastening system 100, while FIGS. 2c and 2d illustrate first and second side elevation assembled views of the fastening system 100 of FIG. 1a with the first and second components 104, 106 omitted. Finally, FIGS. 2e and 2f illustrate, respectively, front and rear views of the fastening system 100, while FIGS. 2g and 2h illustrate, respectively, top and bottom plan views of the fastening system 100.


As illustrated, the fastener 108 comprises a head 108a and a shank 108b. In the illustrated example, the head 108a is square and the shank 108b is threaded. While the fastener 108 is illustrated as a threaded bolt having a head 108a that is hexagonal, other types of fasteners are contemplated. For example, the fastener 108 is illustrated as a flanged bolt having a flange 202 between the head 108a and the threaded shank 108b.


The illustrated nut insert 112 comprise a collar 124, a flange 126, and a bore 128 configured to engage the shank 108b. In some examples, the bore 128 is an internally-threaded bore configured to threadedly engage the shank 108b. The collar 124 is illustrated as cylindrical, but could also be shaped to facilitate tool engagement (e.g., hex-shaped, square, or otherwise). In this example, the nut insert 112 is rotationally fixed relative to the retainer clip 110. Therefore, the modular retainer assembly 102 includes one or more features to rotationally fix and secure the nut insert 112 to mitigating risk of loss of the nut insert 112.


The illustrated nut recess 142 includes one or more anti-rotation features 132 to interact with and mitigate rotation of the flange 126 and a resiliently-attached tongue 138 to receive the collar 124 via a tongue opening 140 and to apply a downward force upon the flange 126 (e.g., pressing the flange 126 against the nut base plate 208d. The flange 126 is shaped interact with the a nut recess 142 of the retainer clip 110 to mitigate rotation of the nut insert 112 relative to the nut recess 142. In the illustrated example, the flange 126 is a quadrilateral (illustrated as a square). With reference to FIGS. 2c and 2d, the illustrated anti-rotation features 132 have a generally U-shaped side profile and are configured to abut one or more sides of the flange 126 when installed, effectively serving as an anti-rotation wall or abutment structure.


The nut insert 112 can be removeably coupled with the retainer clip 110 (e.g., via the nut recess 142) to enable interchangeability of the nut insert 112, thus allowing the retainer clip 110 to be used with various different nut inserts 112 to facilitate different type of fasteners 108 (e.g., those of different threading, diameters, size, materials, etc.). The nut insert 112 can be secured and/or retained relative to the nut recess 142/the retainer clip 110 via the tongue 142 and/or one or more anti-rotation features 132. In some examples, the nut insert 112 can be a non-threaded nut insert to accommodate thread-forming fasteners 108. The retainer clip 110 can be sub-assembled with the nut insert 112 before being pressed onto a first component 104 and packaged as a part-in-assembly (PIA). While the nut insert 112 is illustrated in the form of a one-piece nut insert 112, in other examples, the nut insert 112 can be a multi-component piece.


In some examples, the modular retainer assembly 102 further comprises a seal when desirable to mitigate dust, dirt, and/or moisture penetration through one of the openings (e.g., the first opening 114, the second opening 120, the fastener passage 134, etc.). The seal may be embodied as a ring (e.g., an annulus) and fabricated from foam material, thermoplastic, rubber, etc. For example, a seal can be configured to surround a portion of the fastener 108 (e.g., the shank) and positioned between the second component 106 and nut insert 112. In some examples, a seal can be positioned around the shank 108b between the flange 126 and the second component 106 to form a liquid or gas barrier.


It is contemplated that certain components of the multi-component modular retainer assembly 102 may be fabricated as a stamped-metal component using a metal-stamping technique. For example, the retainer clip 110 can be fabricated from a single sheet of metal and stamped/bent using a metal-stamping technique, while the fastener 108 and/or the nut insert 112 can be fabricated from metal via one or more metal-shaping techniques, such as cold forging. In another example, the retainer clip 110 can be fabricated as a stamped-metal component, whereas the fastener 108 and the nut insert 112 can be fabricated from a plastic material using a plastic injection technique, additive manufacturing, or otherwise. In some examples, one or more components of the modular retainer assembly 102 may be fabricated using material extrusion (e.g., fused deposition modeling (FDM), stereolithography (SLA), selective laser sintering (SLS), material jetting, binder jetting, powder bed fusion, directed energy deposition, VAT photopolymerisation, and/or any other suitable type of additive manufacturing/3D printing process.


The first component 104 and the second component 106 may be, for example, automotive panels or other automotive components. Depending on the application, one or both of the first component 104 and/or the second component 106 may be fabricated from, for example, metal (or a metal alloy), synthetic or semi-synthetic polymers (e.g., plastics, such as acrylonitrile butadiene styrene (ABS) and polyvinyl chloride (PVC), etc.), composite materials (e.g., fiber glass), or a combination thereof. In the automotive industry, example first components 104 include, without limitation, door trim panels, moldings, trim pieces, and other substrates (whether used as interior or exterior surfaces). The second component 106 may be, for example, an automotive panel, a structural component of a vehicle, such as doors, pillars (e.g., an A-pillar, B-pillar, C-pillar, etc.), dashboard components (e.g., a cross member, bracket, frame, etc.), seat frames, center consoles, fenders, sheet metal framework, or the like. Depending on the application, the first component 104 and/or the second component 106 may be fabricated from, for example, metal (or a metal alloy), synthetic or semi-synthetic polymers (e.g., plastics, such as acrylonitrile butadiene styrene (ABS) and polyvinyl chloride (PVC), etc.), composite materials (e.g., fiber glass), or a combination thereof.


The first component 104 and the second component 106 are shaped such that they can interact with the interior geometry of the retainer clip 110. For example, the illustrated first component 104 defines a set of sloped wings 152 that are configured (e.g., sized, shaped, and spaced) to receive a portion of the retainer clip 110 therebetween to mitigate, for example, side-to-side movement between the first component 104 and the retainer clip 110. The illustrated second component 106 defines a wall 150 (e.g., illustrated as a 90-degree bend, but other angles are contemplated) at its distal edge that is configured to slide laterally into the channel 130 to mitigate, for example, pull out of the second component 106 from the retainer clip 110 in a direction opposite of arrow 116.


During installation, as best illustrated in FIG. 1c, the nut insert 112 is inserted into the nut recess 142 of the retainer clip 110 as indicated by arrow 148 and retained via one or more anti-rotation features 132. In this example, the approach angle of the nut insert 112 indicated by the arrow 148 is slightly pitched or angled to enable the user to slip the nut insert 112 into the nut recess 142 and secured via the one or more anti-rotation features 132. The first component 104 is slid into the channel 130 of the retainer clip 110 as indicated by arrow 116 such that the first opening 114 aligns with the fastener passage 134. The second component 106 is slid into the channel 130 of the retainer clip 110 as indicated by arrow 146 such that the second opening 120 aligns with the fastener passage 134. In this example, the direction indicated by arrow 116 is substantially perpendicular to the direction indicated by arrow 146 as the second component 106 is slid into the channel 130 laterally to accommodate the wall 150.


Once the first opening 114, the second opening 120, and the fastener passage 134 are aligned (e.g., generally concentric and aligned with the axis of rotation 122), an end of the shank 108b is passed through each of the fastener passage 134 formed in the retainer clip 110, the first opening 114, and the second opening 120, as indicated by arrow 118 to ultimately engage the nut insert 112. The fastener 108 and/or the nut insert 112 can be rotated relative to one another about its axis of rotation 122 to join and compress the first component 104 and second component 106 relative to one another. For example, the fastener 108 can be rotated about its axis of rotation 122 via the head 108a.


With reference to FIGS. 2a through 2h, the illustrated retainer clip 110 comprises a body portion 208 that defines the channel 130 (e.g., a U-shaped channel) to receive the first component 104 and the second component 106 and the nut recess 142. The retainer clip 110 can further comprises one of more tabs 144 formed in or on the body portion 208 (e.g., the first planar portion 208a) of the retainer clip 110.


The illustrated body portion 208 is formed as a pair of first and second planar portions 208a, 208b that are resiliently connected at an end via a bend 208c (e.g., a spring clip). As illustrated, the first and second planar portions 208a, 208b are generally parallel and the bend 208c is shaped to accommodate a combined panel thickness for the first and second components 104, 106. The pair of opposing first and second planar portions 208a, 208b are resiliently connected at the bend 208c such that the pair of opposing first and second planar portions 208a, 208b default (e.g., spring back) to a predetermined shape. The channel 130 is sized to receive a least a portion of the first component 104 and the second component 106. In the illustrated example, the second planar portion 208b defines a first passage opening 134a. In the illustrated example, a panel tab 136 is also positioned at the fastener passage 134 (e.g., formed along the inner perimeter for the first passage opening 134a) and generally U-shaped to at least partially encircle or surround the shank 108b when assembled. In use, the panel tab 136 is configured to snap into a corresponding feature (e.g., on an adjacent component to creating audible/tactile feedback during installation.


The illustrated first planar portion 208a is stamped and bent to form a nut base plate 208d that is resiliently connected to the first planar portion 208a at one end adjacent a guide lip 204 at an opening to the channel 130. The guide lip 204 can be shaped at an angle to guide the first component into the channel 130 during assembly. In addition, the guide lip 204 can provide a bearing area for manipulation during assembly by an operator.


As illustrated, the nut base plate 208d can be punched from the first planar portion 208a and bent to extend into the channel 130. In the illustrated example, the nut base plate 208d defines a second passage opening 134b and, together with the first passage opening 134a, defines the fastener passage 134. The nut base plate 208d is generally parallel to the first and second planar portions 208a, 208b and configured to sandwich the first and second components 104, 106 therebetween. While the first and second planar portions 208a, 208b are illustrated as parallel, the first and second planar portions 208a, 208b could be non-parallel to, for example, facilitate a variable panel thickness.


In addition to defining the second passage opening 134b, the nut base plate 208d defines serves as the base to the nut recess 142 and supports the nut insert 112 via a bottom surface of the flange 126. When assembled, the nut insert 112 resides within the nut recess 142 defined by the nut base plate 208d, the one or more anti-rotation features 132, and the tongue 138 such that it is prevented from rotating about its axis of rotation 122 via, inter alia, the sidewalls of the anti-rotation features 132.


The retainer clip 110 further comprises one or more anti-rotation features 132 at the nut base plate 208d to retain and rotationally fix the nut insert 112 by capturing the flange 126. The one or more anti-rotation features 132 can be positioned at one or more sides of the perimeter of the nut recess 142 (illustrated as being located at two, opposing sides). The flange 126 can snap through anti-rotation features 132 in the retainer clip 110. In the illustrated example, the nut base plate 208d includes two anti-rotation feature 132 (one on each side of the nut recess 142). The anti-rotation features 132 abut or otherwise rests against a surface of the flange 126 (e.g., a straight edge) to provide resistance to torque during assembly with the nut insert 112.



FIGS. 3a through 3f illustrate various views of an example of a retainer clip 110 for the fastening system 100 with the nut insert 112 omitted for clarity. Specifically, FIGS. 3a and 3b illustrate, respectively, topside and underside isometric views of a retainer clip 110 of the modular retainer assembly 102 in accordance with an aspect of this disclosure. FIGS. 3c and 3d illustrate first and second side elevation assembled views of the retainer clip 110, while FIGS. 3e and 3f illustrate, respectively, front and rear views of the retainer clip 110 and FIGS. 3g and 3h illustrate, respectively, top and bottom plan views of the retainer clip 110. As noted, the retainer clip 110 is a stamped-metal component. As such, the various features of the retainer clip 110 (e.g., nut recess 142, anti-rotation features 132, one of more tabs 144) can be stamped and/or punched from the material of the body portion 208 and bent to shape.
