[0003] Embodiments of the present disclosure generally relate to vehicle panel components and, more particularly, to double - engagement fasteners. Background Art

[0004] In recent years, fasteners for joining multiple vehicle panels together have been developed. Certain known fasteners (e.g., rivets, bolts, screws, etc.) are inserted through a first panel and a second panel to hold the panels together. In some cases, opposite ends of these known fasteners engage opposite outer surfaces of the panels. In some cases, the ends of these known fasteners are threaded into one of the panels.

[0005] However, these known fasteners require multiple steps to join the panels together. Additionally, it is generally difficult to align the panels using these known fasteners to a specific tolerance. Accordingly, there is a need for a fastener that is easy to install and helps to align the panels to a desired tolerance between the panels. Summary of the Invention

The second U-shaped connector 190 includes a fourth connector wall 192, a fifth connector wall 194, a sixth connector wall 196, and a notch 198. The key 182 is fitted into the notch 198 to fix the first mounting seat 162 to the second mounting seat 164. The third clamping leg 166 includes a third plurality of teeth 202. The third plurality of teeth 202 extend radially outward. The fourth clamping leg 168 includes a fourth plurality of teeth 204. The fourth plurality of teeth 204 extend radially outward.

[0048] Referring to Figure 2 , the washer 112 is annular and defines an opening 208.

[0049] Referring to Figure 8 , the first exemplary fastener assembly 100 operates in conjunction with a first panel 212 (e.g., a vehicle trunk lid) and a second panel 214 (e.g., a spoiler). The first panel 212 includes a top side 218. Referring to Figure 9 , the first panel 212 further includes a bottom side 220. The first panel 212 defines an opening 222. The second panel 214 includes a mounting protrusion 226, a recessed surface 228, and a bottom surface 230. The mounting protrusion 226 and the recessed surface define a keyhole slot 232.

[0050] Referring to Figure 5 , Figure 7 and <( Figure 19, the end wall 118 is connected to the cylindrical wall 116. The first rib 122, the second rib 124, and the third rib 126 are connected to the end wall 118 and extend from the end wall. The second rib 124 is located between the first rib 122 and the third rib 126. The first clamping leg 140 and the second clamping leg 142 extend from the end wall 118. In other words, the first clamping leg 140 and the second clamping leg 142 are connected to the end wall 118 and extend from the end wall in a direction opposite to that of the first rib 122, the second rib 124, and the third rib 126. Therefore, the first clamping leg 140 and the second clamping leg 142 can pivot within the cavity 158. The cylindrical wall 116 extends from the end wall 118 in a direction opposite to that of the first rib 122, the second rib 124, and the third rib 126. The first rib 122 and the first clamping leg 140 extend from the end wall 118 in opposite directions. Therefore, the first rib 122 and the first clamping leg 140 are connected to each other via the end wall 118. The third rib 126 and the second clamping leg 142 extend from the end wall 118 in opposite directions. Therefore, the third rib 126 and the second clamping leg 142 are connected to each other via the end wall 118. The first clamping leg 140 and the second clamping leg 142 are disposed within the cylindrical wall 116. The first plurality of teeth 146 face the second plurality of teeth 148. The first snap wing 130 is elastically and pivotally connected to the first rib 122 and extends obliquely outward from the first rib toward the cylindrical wall 116. The second snap wing 132 is elastically and pivotally connected to the third rib 126 and extends obliquely outward from the third rib toward the cylindrical wall 116.

[0051] Referring to Figure 5 , Figure 7 and Figure 19 , the first mount 162 engages with the second mount 164. The third clamping leg 166 engages with the fourth clamping leg 168. The third clamping leg 166 is elastically and pivotally connected to the first mount 162 and extends from the first mount. The fourth clamping leg 168 is elastically and pivotally connected to the second mount 164 and extends from the second mount.

[0052] Referring to Figure 7 and Figure 19 , the first flange 172 is connected to the first U-shaped connector 174 and extends away from the first U-shaped connector. More specifically, the first flange 172 extends radially outward from the third connector wall 180. The second connector wall 178 engages with the first connector wall 176 and the third connector wall 180. The key 182 is connected to the third connector wall 180 and extends from the third connector wall in a direction opposite to that of the first flange 172.

[0053] Referring to Figure 7 and Figure 19, the second flange 188 is connected to the second U-shaped connector 190 and extends away from the second U-shaped connector. More specifically, the second flange 188 extends radially outward from the sixth connector wall 196. The fifth connector wall 194 engages the fourth connector wall 192 and the sixth connector wall 196. The sixth connector wall 196 defines a notch 198.

[0054] Referring to Figure 7 and Figure 19 , the third plurality of teeth 202 and the fourth plurality of teeth 204 face outward. The third plurality of teeth 202 and the fourth plurality of teeth 204 are opposite to each other. Referring to Figure 7 , the first plurality of teeth 146 and the third plurality of teeth 202 engage with each other in a ratchet manner. In addition, the second plurality of teeth 148 and the fourth plurality of teeth 204 engage with each other in a ratchet manner.

[0055] Referring to Figure 1 , Figure 6 , Figure 7 and Figures 12 to 19 , the insert 108 is configured to be inserted into the base 104. Referring to Figure 1 , Figure 7 and Figures 12 to 19 , the washer 112 is configured to engage the base 104 around the first rib 122, the second rib 124, and the third rib 126. Accordingly, the first rib 122, the second rib 124, and the third rib 126 extend through the washer 112.

[0056] Referring to Figure 7 and Figure 19 , the first plurality of teeth 146 are complementary to the third plurality of teeth 202. The second plurality of teeth 148 are complementary to the fourth plurality of teeth 204. In operation, when the insert 108 is pushed into the cavity 158 between the first clamping leg 140 and the second clamping leg 142, the first clamping leg 140 and the second clamping leg 142 elastically bend away from each other and snap back. Further in operation, as the insert 108 is pushed between the first clamping leg 140 and the second clamping leg 142, the first plurality of teeth 146 engage the third plurality of teeth 202 in a ratchet manner. Additionally, in operation, as the insert 108 is pushed between the first clamping leg 140 and the second clamping leg 142, the second plurality of teeth 148 engage the fourth plurality of teeth 204 in a ratchet manner. Accordingly, the insert 108 is held in the base 104 via the first plurality of teeth 146, the second plurality of teeth 148, the third plurality of teeth 202, and the fourth plurality of teeth 204. In other words, the insert 108 is received in the cavity 158 defined by the base 104.

[0057] Referring to Figure 10 and Figure 11, in operation, to assemble the first exemplary fastener assembly 100 with the first panel 212 and the second panel 214, in some cases, the base 104 can be initially assembled with the first panel 212 and the insert 108 can be initially assembled with the second panel 214. Refer to Figure 10 , when the base 104 is inserted into the first panel 212, the washer 112 is captured between the base 104 and the top side 218. Refer to Figure 11 , it should be understood that the first rib 122, the second rib 124, and the third rib 126 guide the insertion of the base 104 through the opening 222. More specifically, the first sharp end 152, the second sharp end 154, and the third sharp end 156 serve as guiding features to facilitate the insertion of the base 104 into the opening 222. Refer to Figure 16 and Figure 17 , the insert 108 can then be inserted into the base 104 to fasten the second panel 214 to the first panel 212.

[0058] Refer to Figure 12 and Figure 13 , in operation, to assemble the first exemplary fastener assembly 100 with the first panel 212 and the second panel 214, in some cases, the insert 108 can be initially inserted into the base 104. Refer to Figure 14 and Figure 15 , the insert 108 can then be installed onto the second panel 214. When the insert 108 is installed onto the second panel 214, the first flange 172 and the second flange 188 are disposed in the keyhole slot 232 to engage the mounting protrusion 226 and the recessed surface 228. Refer to Figure 17 , the base 104 can then be installed onto the first panel 212.

[0059] Refer to Figure 19 , in operation, to install the base 104 onto the first panel 212, the first snap wing 130 and the second snap wing 132 are pushed through the opening 222. As the first snap wing 130 and the second snap wing 132 pass through the first panel 212 from the top side 218 to the bottom side 220 via the opening 222, the first snap wing 130 and the second snap wing 132 flex inwardly towards each other. When the first snap wing 130 and the second snap wing 132 exit the opening 222 at the bottom side 220, the first snap wing 130 and the second snap wing 132 rebound outwardly relative to each other to engage the first shoulder 134 and the second shoulder 136 with the bottom side 220. Thus, when the first exemplary fastener assembly 100 is installed onto the first panel 212, the first snap wing 130 and the second snap wing 132 can snap-engage the first panel 212.

[0060] Refer to Figure 19, in operation, the first rib 122 can be pushed in a first direction 234 to approach the second rib 124. Additionally, in operation, the third rib 126 can be pushed in a second direction 236 to approach the second rib 124. When the first rib 122 is pushed in the first direction 234, the first clamping leg 140 pivots in a third direction 238 to release the first plurality of teeth 146 from the third plurality of teeth 202. Further in operation, when the third rib 126 is pushed in the second direction 236, the second clamping leg 142 pivots in a fourth direction 240 to release the second plurality of teeth 148 from the fourth plurality of teeth 204. In other words, the first clamping leg 140 and the first rib 122 are pivotally connected to the end wall 118. Additionally, the second clamping leg 142 and the second rib 124 are pivotally connected to the end wall 118. Thus, when the first rib 122 and the third rib 126 are squeezed together (e.g., by an operator's finger), the first clamping leg 140 and the second clamping leg 142 release the insert 108. In other words, the insert 108 can be selectively removed and / or released from the base 104.

[0061] Referring to Figures 20 to 30 , the second exemplary fastener assembly 300 includes a second exemplary base 304, a second exemplary insert 308, and a washer 312. In some embodiments, the base 304 and the insert 308 are formed of a thermoplastic polymer (e.g., polyoxymethylene resin (POM) or nylon). In some embodiments, the thermoplastic polymer is infused with glass fiber. In some embodiments, the washer 312 is formed of a thermoplastic elastomer (TPE).

[0062] Referring to Figure 23 , the base 304 includes a body 316, a flange 318, a first snap wing 322, and a second snap wing 324. The first snap wing 322 includes a first shoulder 326. The first shoulder 326 extends outwardly. The second snap wing 324 includes a second shoulder 328. The second shoulder 328 extends outwardly. The body 316 includes a conical end 332. The body 316 defines an opening 336 passing through the conical end 332. Referring to Figure 24 , the body 316 defines a first groove 338, a second groove 340, and a cavity 344. The first groove 338 and the second groove 340 are generally parallel. The cavity 344 is located between the first groove 338 and the second groove 340. The body 316 includes a first plurality of teeth 346 and a second plurality of teeth 348.

[0063] Referring to Figure 22 , the insert 308 includes a first mounting protrusion 352, a second mounting protrusion 354, a connecting wall 356, a first clamping leg 358, a second clamping leg 360, a third plurality of teeth 362, a fourth plurality of teeth 364, and a leaf spring 366.

[0064] Referring to Figure 21, the washer 312 is annular and defines an opening 370 and an annular groove 372.

[0065] Referring to Figure 24 , the flange 318 extends radially outward from the body 316. Referring to Figure 23 , the first latching wing 322 extends obliquely outward from the body 316. The second latching wing 324 extends diagonally outward from the body 316. Referring to Figure 24 , the body 316 includes a first plurality of teeth 346 that extend inwardly into the cavity 344. A second plurality of teeth 348 extend inwardly into the cavity 344. The first plurality of teeth 346 and the second plurality of teeth 348 face each other.

[0066] Referring to Figure 24 , the first mounting protrusion 352 and the second mounting protrusion 354 extend laterally outward from the connecting wall 356. The first clamping leg 358 and the second clamping leg 360 extend from the connecting wall 356. The first clamping leg 358 and the second clamping leg 360 are generally parallel to each other. A third plurality of teeth 362 extend outward from the first clamping leg 358. A fourth plurality of teeth 364 extend outward from the second clamping leg 360. The leaf spring 366 is between the first clamping leg 358 and the second clamping leg 360 and is connected to the first clamping leg and the second clamping leg. Thus, the leaf spring 366 is between the third plurality of teeth 362 and the fourth plurality of teeth 364.

[0067] Referring to Figure 27 , the first plurality of teeth 346 are complementary to the third plurality of teeth 362. The second plurality of teeth 348 are complementary to the fourth plurality of teeth 364. In operation, to assemble the second exemplary fastener assembly 300, the insert 308 is pushed into the base 304. Additionally, the washer 312 engages the flange 318 via the annular groove 372. More specifically, the flange 318 is inserted into the annular groove 372. Referring to Figure 29 , in operation, when the insert 308 is pushed into the base 304, the first clamping leg 358 and the second clamping leg 360 flex towards each other to compress the leaf spring 366. Further, as the insert 308 is pushed into the base 304, the first plurality of teeth 346 engage the third plurality of teeth 362 ratchet - like. Additionally, as the insert 308 is pushed into the base 304, the second plurality of teeth 348 engage the fourth plurality of teeth 364 ratchet - like. The leaf spring 366 pushes the first clamping leg 358 and the second clamping leg 360 outward to separate them. Thus, the first plurality of teeth 346 remain engaged with the third plurality of teeth 362, and the second plurality of teeth 348 remain engaged with the fourth plurality of teeth 364. In other words, the insert 308 is received in the cavity 344 defined by the base 304.

[0068] Referring to Figure 29, further in operation, the insert 308 is slidably mounted to the second panel 214 via the keyhole slot 232. The first mounting protrusion 352 and the second mounting protrusion 354 engage with the recessed surface 228. The first mounting protrusion 352 and the second mounting protrusion 354 are retained in the second panel 214 by the mounting protrusion 226.

[0069] Referring Figure 31 , in operation, to mount the base 304 to the first panel 212, the first snap wing 322 and the second snap wing 324 are pushed through the opening 222. As the first snap wing 322 and the second snap wing 324 pass through the first panel 212 from the top side 218 to the bottom side 220 via the opening 222, the first snap wing 322 and the second snap wing 324 flex inwardly towards each other. When the first snap wing 322 and the second snap wing 324 exit the opening 222 at the bottom side 220, the first snap wing 322 and the second snap wing 324 elastically rebound outwardly relative to each other so that the first shoulder 326 and the second shoulder 328 engage with the bottom side 220. Thus, when the first exemplary fastener assembly 100 is mounted to the first panel 212, the first snap wing 130 and the second snap wing 132 can snap-engage with the first panel 212. Additionally, when the base 304 is snap-received in the first panel 212, the washer 312 is compressed between the flange 318 and the top side 218.

[0070] Referring Figure 31 , in operation, in some cases, the base 304 is pushed into the first panel 212 via the flange 318. In some cases, a tool (e.g., a hex wrench, a cord, a string, etc.) (not shown) can be inserted into the opening 336 to pull the base 304 through the opening 222.
