[0030] Figure 1 shows the overall structure of the fastening clip assembly 100 according to an embodiment of the present application. In Figure 1 , the fastening clip assembly 100 is in the pre-assembled state. The fastening clip assembly 100 can be inserted into a hole of an automotive component (such as automotive sheet metal) to fasten an accessory such as an airbag to the automotive component. For the convenience of description, the coordinate system in Figure 1 is used to represent the directions of the fastening clip assembly 100. Among them, the X-axis direction represents the width direction of the fastening clip assembly 100, the Y-axis direction represents the length direction of the fastening clip assembly 100, and the Z-axis direction represents the thickness direction of the fastening clip assembly 100. The above directions are relative and cannot be regarded as a limitation of the present invention.

[0031] As Figure 1 shown, the fastening clip assembly 100 includes a clip 120 and an insert 130. The clip 120 is used to engage the fastening clip assembly 100 with an automotive component (such as a plate with a hole) at a use position, while the insert 130 is used to maintain the engagement state between the clip 120 and the automotive component. In a pre-assembled state, the insert 130 is assembled on the clip 120 and held on the clip 120, so that the two form a pre-assembled component. The clip 120 is made of a metallic material, and the insert 130 is made of a plastic material. The fastening clip assembly 100 in the pre-assembled state is suitable for the sale, transportation, etc. of the fastening clip assembly 100.

[0032] Figure 2A and 2B show the specific structure of the clip 120, where Figure 2A is a perspective view of the clip 120, Figure 2B is a cross-sectional view of the clip 120. As Figure 2A and 2B shown, the clip 120 includes a head 220, a body 240, and a pair of retaining portions 260. The clip 120 is integrally formed from a metallic material such as steel by processes such as bending, stamping, shearing, etc. The pair of retaining portions 260 are deflectable relative to each other.

[0033] The body 240 includes two pairs of side walls, namely, a first pair of side walls 242 and a second pair of side walls 244, and the two pairs of side walls are respectively arranged opposite to each other. The body 240 defines an internal cavity 245 of the clip 120, which is located between the first pair of side walls 242 and between the second pair of side walls 244. Windows 241 are respectively provided on the first pair of side walls 242, and the windows 241 communicate the internal cavity 245 of the clip 120 with the outside. Limiting grooves 243 extending in the length direction are also provided on the first pair of side walls 242, and the limiting grooves 243 are located below the windows 241 and communicate with the windows 241. In addition, the clip 120 includes a receiving groove 280, and the receiving groove 280 is provided at the connection between the first pair of side walls 242 and the head 220. The first pair of side walls 242 include opposite first ends 247 and second ends 248. The first pair of side walls 242 further include side wall extensions 249 provided at their second ends 248, and the side wall extensions 249 are slightly inclined inward relative to the side walls 242.

[0034] The head 220 is generally flat, is connected to the first ends 247 of the first pair of side walls 242, and is provided with an opening 225. The opening 225 communicates with the internal cavity 245. The head 220 thus protrudes outward relative to the first pair of side walls 242. In some embodiments, the head 220 extends in a direction perpendicular to the side walls 242.

[0035] A pair of retaining portions 260 are respectively connected to sidewall extensions 249 at the second ends 248 of the first pair of sidewalls 242. The retaining portions 260 extend from the sidewall extensions 249 and are bent in a special manner. The retaining portions 260 include a retaining segment 261 and a free end segment 262, and the retaining segment 261 abuts against the sidewall extension 249.

[0036] The retaining segments 261 of the two retaining portions 260 extend from the sidewall extensions 249 on the corresponding sidewalls 242 towards the head 220. A part of the retaining segment 261 extends obliquely outwards through the corresponding window 241 from the inner cavity 245 of the clip 120, that is, projects through the window 241. After extending outwards, the retaining segment 261 bends back and extends in the width direction, so that the connected end segment 262 returns to the inner cavity 245 of the clip 120. Therefore, the retaining segment 261 includes an inclined portion and a laterally extending portion that form an acute angle with each other, and the laterally extending portion extends in the width direction. The pair of retaining portions 260 can deflect towards and away from each other, so that the retaining segments 261 of the pair of retaining portions 260 can project from the corresponding windows 241 and can also return to the inner cavity 245 of the clip 120.

[0037] The retaining portion 260 is provided with a cut 273 that extends in the width direction to divide the laterally extending portion and the end segment 262 of the retaining segment 261 into two parts. Each end segment 262 includes a driving portion 272 and a blocking portion 274 separated by the cut 273. The driving portion 272 extends from the retaining segment 261 towards the head 220, while the blocking portion 274 extends from the retaining segment 261 away from the head 220. The driving portions 272 on the two retaining portions 260 are staggeredly arranged in the thickness direction and are respectively located on opposite sides of the cut 273. The blocking portion 274 can hang on the edge of the window 241 of the sidewall 242 to increase the retaining force of the retaining portion 260.

[0038] The clip 130 further includes a plurality of tabs 223 provided on the head 220. They are provided on the edge of the head 220 that extends in the width direction and extend downward from the head 220 for separating the insert 130 of the fastening clip assembly 100 from the part to be fastened (such as an airbag) in the use state of the fastening clip assembly 100.

[0039] Figure 3 is Figure 1 A perspective view of the insert 130 of the fastening clip assembly 100 shown, which shows the specific structure of the insert 130. As Figure 3 shown, the insert 130 includes a base 320, a pair of legs 340, a pair of verification elements 350, a pair of locking arms 360, a pair of driven sheets 370, and a pair of fins 380.

[0040] A pair of legs 340 extend from the base 320 and generally extend in the longitudinal direction. In the free state where the insert 130 is not under force, there is a certain distance between the pair of legs 340. The proximal ends 341 of the pair of legs 340 are connected to the base 320, and the pair of legs 340 can deflect towards and away from each other about their proximal ends 341.

[0041] A pair of verification elements 350 are respectively provided at the distal ends 342 of the pair of legs 340 and protrude outward from the corresponding legs 340. A pair of driven pieces 370 are also respectively provided at the distal ends 342 of the pair of legs 340, and the pair of driven pieces 370 are located between the pair of verification elements 350 in the width direction.

[0042] Still referring to Figure 3 , a pair of locking arms 360 are respectively connected to the pair of legs 340 and are located outside the legs 340. The locking arms 360 are connected to the legs 340 at their proximal ends near the distal ends 342 of the legs 340. The locking arms 360 extend downward towards the base 320 and can deflect towards and away from the corresponding legs 340. The distal ends of the locking arms 360 are provided with feet 362, and the feet 362 are generally hook-shaped. A pair of fins 380 are connected to opposite sides of the base 320 and can deflect relative to the base 320. In the free state without force, the pair of fins 380 together form a V-shaped configuration.

[0043] Figure 4A and 4B show the mating relationship between the clip 120 and the insert 130 when the fastening clip assembly 100 is in the pre-assembled state, where Figure 4A is a side view of the fastening clip assembly 100, Figure 4B is a cross-sectional view taken along line A-A in Figure 4A . As shown in Figure 4A and 4B , when the fastening clip assembly 100 is in the pre-assembled state, the legs 340 of the insert 130 together with the verification elements 350, locking arms 360 and driven pieces 370 connected thereto pass through the opening 225 in the head 220 of the clip 120 and enter the internal cavity 245 of the clip 120, while the base 320 and fins 380 of the insert 130 cannot enter the opening 225 but are blocked by the head 220 outside the internal cavity 245. A pair of verification elements 350 respectively pass through the limit slots 243 in a pair of side walls 242 of the clip 120 and protrude out of the internal cavity 245, so that the verification elements 350 cooperate with the limit slots 243 to restrict the insert 130 from being pulled out of the clip 120, thereby holding the insert 130 on the clip 120 and making the two a pre-assembled part.

[0044] During the pre-assembly of the insert 130 to the clip 120, a pair of verification elements 350 first come into contact with a pair of edges extending in the thickness direction of the opening 225 of the head 220 of the clip 120. Since, in the unloaded state, the distance between the outer sides of the pair of verification elements 350 is greater than the distance between the pair of edges extending in the thickness direction of the opening 225, the operator needs to first apply a force to the pair of legs 340 to deflect them towards each other, so as to reduce the distance between the outer sides of the pair of verification elements 350 and enable them to enter the opening 225. When the pair of verification elements 350 enter the opening 225, the pair of edges extending in the thickness direction of the opening 225 apply a force to the verification elements 350 to keep the pair of legs 340 in a deflected state towards each other. When the pair of verification elements 350 pass through the opening 225 and align with the limit slots 243 on the side wall 242, the legs 340 are no longer subject to the force deflecting them towards each other, and the verification elements 350 move outwards under the action of the resilience of the legs 340 and pass through the limit slots 243 on the side wall 242 to reach outside the internal cavity 245, thereby holding the insert 130 on the clip 120.

[0045] Still as Figure 4B shown, when the fastening clip assembly 100 is in the pre-assembled state, a pair of driven pieces 370 of the insert 130 are respectively aligned with the corresponding driving parts 272, so that when the pair of driving parts 272 move towards each other, the pair of driving parts 272 can respectively drive the corresponding driven pieces 370 to move the pair of driven pieces 370 towards each other as well. In addition, a part of the pair of locking arms 360 is still located in the opening 225 and is squeezed by the pair of edges extending in the thickness direction of the opening 225 to deflect towards each other.

[0046] Figure 5A and 5B show the mating relationship between the clip 120 and the insert 130 when the fastening clip assembly 100 is in the use state, where Figure 5A is a side view of the fastening clip assembly 100, Figure 5B is a cross-sectional view taken along the line B-B in Figure 5A . In the use environment shown in Figure 5A and 5B , the fastening clip assembly 100 fastens a certain part (such as an airbag) to the plate 500, and at least a part of the fastening clip assembly 100 passes through the hole 520 of the plate 500.

[0047] As Figure 5BAs shown, when the fastening clip assembly 100 is in use, the holding portion 260 of the clip 120 passes through the hole 520 of the plate 500 and is located above the plate 500. A pair of fins 380 abut against the head 220 and are unfolded. The feet 362 of a pair of locking arms 360 engage with the edge of the opening 225 of the head 220 of the clip 120, and a part of them is received in the receiving groove 280 on the head 220. A pair of verification elements 350 are located between and abut against the inclined portions of the holding section 261 of the holding portion 260 of the clip 120. The above mating relationship restricts the insert 130 from being pulled out of the clip 120, thereby restricting the holding portion 260 of the clip 120 from moving towards each other and disengaging from the hole 520, so that the clip 120 and the fastening clip assembly 100 can be held in the use state.

[0048] During the process of the fastening clip assembly 100 transitioning from Figure 4A and 4B the pre-assembled state shown to Figure 5A and 5B the use state shown, the holding portion 260 of the clip 120 first deflects (moves) towards each other under the action of a pair of edges of the hole 520 of the plate 500, so that the holding portion 260 gradually passes through the hole 520. During this process, the driven portion 370 of the insert 130 drives a pair of legs 340 to deflect towards each other under the action of the driving portion 272 on the holding portion 260 of the clip 120, and thereby causes a pair of verification elements 350 to also move towards each other and leave the limiting groove 243 on the side wall 242. Before the holding portion 260 of the clip 120 completely passes through the hole 520, the driven portion 370 of the insert 130 remains engaged with the driving portion 272 on the holding portion 260 of the clip 120. Thus, when the holding portion 260 of the clip 120 moves towards each other to be able to completely pass through the hole 520, a pair of verification elements 350 can also pass through the hole 520, and a pair of verification elements 350 are exactly located in the hole 520. After the holding portion 260 of the clip 120 completely passes through the hole 520, the holding portion 260 bounces outwards under the action of elastic force, and a pair of verification elements 350 engage with the edge of the hole 520, so that a pair of legs 340 are still in the state of deflecting towards each other under the action of the edge of the hole 520. Therefore, the driven portion 370 of the insert 130 disengages from the driving portion 272 on the holding portion 260 of the clip 120, which enables the insert 130 to move towards the plate 500 relative to the clip 120 and further insert into the internal cavity 245 of the clip 120, thereby reaching Figure 5B the use state shown. In Figure 5B the state shown, a pair of verification elements 350 of the insert 130 respectively abut against the inclined portions of the holding section 261 of a pair of holding portions 260.

[0049] Figure 6Shows the overall structure of a fastening clip assembly 600 according to another embodiment of the present application. As Figure 6 shown, the fastening clip assembly 600 includes a clip 620 and an insert 630. Figure 6 The fastening clip assembly 600 in the illustrated embodiment is similar to Figure 1 the fastening clip assembly 100 in the illustrated embodiment. The main difference is that the fastening clip assembly 100 is provided with a pair of locking arms 360, while the fastening clip assembly 600 is provided with a pair of additional locking arms in addition to a pair of locking arms.

[0050] Figures 7A to 7C Shows Figure 6 the specific structure of the clip 620 of the fastening clip assembly 600 in Figure 2A and 2B The structure of the clip 620 is generally similar to that of the clip 220 shown in. The main difference is that no additional receiving groove is provided on the side wall 742 of the clip 620. In addition, the clip 620 is provided with a pair of extension grooves 727 on a pair of sides of the hole 725 in the head 720, and the pair of extension grooves 727 communicate with the hole 725. Similar to the clip 220, the head 720 and the holding portion 760 of the clip 620 are respectively connected to the first end 747 and the second end 748 of a pair of side walls 742. For other specific structures of the clip 620, refer to the above detailed description of the clip 220, which will not be elaborated here.

[0051] Figure 8 Shows Figure 6 the specific structure of the insert 630 of the fastening clip assembly 600 in Figure 3 The structure of the insert 630 is generally similar to that of the insert 230 shown in. The main difference is that a pair of locking arms 360 are provided on the leg 340 of the insert 230, while a pair of locking arms 860 and a pair of additional locking arms 830 are provided between the proximal end 841 and the distal end 842 of the leg 840 of the insert 630, and both the pair of locking arms 860 and the pair of additional locking arms 830 extend towards the proximal end 841 of the leg 840.

[0052] As Figure 8 shown, the additional locking arm 830 is located above the locking arm 860, that is, between the locking arm 860 and the distal end 842 of the leg 840. The additional locking arm 830 includes a foot 832 provided at its free end. And Figure 3The hooked feet of the locking arm 330 of the insert 230 in the illustrated embodiment are different. The feet 832 of the additional locking arm 830 are not hooked. The feet 832 of the additional locking arm 830 are smaller in width than the rest of the additional locking arm 830. The locking arm 860 gradually widens in the direction from its connection end with the leg 840 to the free end 862, so the locking arm 860 has a widened free end 862. The width of the free end 862 of the locking arm 860 is greater than the width of the feet 832 of the additional locking arm 830. The widths of the above-mentioned feet and free ends refer to the dimensions in the thickness direction of the fastening clip assembly. The above arrangements of the locking arm 860 and the additional locking arm 830 of the insert 630 make the locking arm 860 and the additional locking arm 830 have relatively high strength, so that a relatively large holding force can be provided.

[0053] The size of the limit groove 743 on the side wall 742 of the clip 620 is set to be able to receive the feet 832 of the additional locking arm 830, but not the rest of the additional locking arm 830. And the size of the limit groove 743 is set to be able to receive the verification part 850 of the insert 630 to pre-assemble the insert 630 in the clip 620.

[0054] In addition, the size of the extension groove 727 on the head 720 of the clip 620 is set to allow the feet 832 of the additional locking arm 830 to pass through it, but not allow the free end 862 of the locking arm 860 to pass through it.

[0055] Still referring to Figure 8 , on the outer sides of the proximal ends 841 of a pair of legs 840 of the insert 630, there are respectively provided outwardly protruding limit bosses 870.

[0056] For the other specific structure of the insert 630, refer to the above detailed introduction of the insert 230, and it will not be elaborated here.

[0057] Figure 9A and 9B show the mating relationship between the clip 620 and the insert 630 when the fastening clip assembly 600 is in the pre-assembled state. The way the insert 630 is held on the clip 620 is the same as the way the insert 130 shown in Figure 4A and 4B is held on the clip 120, and it will not be elaborated here.

[0058] Figure 10A and 10B show the mating relationship between the clip 620 and the insert 630 when the fastening clip assembly 600 is in the use state. As shown in Figure 10A and 10BAs shown, when the fastening clip assembly 600 is in use, the foot 832 of the additional locking arm 830 is received in the limiting groove 743 on the clip 620, and the remaining part of the additional locking arm 830 cannot enter the limiting groove 743. The free end 862 of the locking arm 860 is adjacent to or engages with the inner surface 726 of the head 720 of the clip 620. Therefore, when an outward pulling force is applied to the insert 630, through the cooperation of the locking arm 860 and the head 720, and through the cooperation of the additional locking arm 830 and the side wall 742, the locking arm 860 and the additional locking arm 830 can be held in the inner cavity 745 of the clip 620, so that the insert 630 can prevent the holding part 760 of the clip 620 from withdrawing from the hole of the component 500, thereby holding the fastening clip assembly 600 in the use state.

[0059] Still as Figure 10A and 10B As shown, when the fastening clip assembly 600 is in use, the limiting bosses 870 on a pair of legs 840 of the insert 630 are received in the openings 725 on the head 720 of the clip 620. Since the size of the openings 725 is set such that the locking arm 860 and the additional locking arm 830 of the insert 630 can pass through them, after the locking arm 860 and the additional locking arm 830 pass through the openings 725, if there are no limiting bosses 870, there will be a large gap between the openings 725 and the legs 840, which will cause the insert 630 to wobble in the clip 620. By providing the limiting bosses 870 and setting the size of the limiting bosses 870 to be able to cooperate with the edges in the thickness direction of the openings 725, the wobbling of the insert 630 in the clip 620 can be restricted.

[0060] The fastening clip assembly of the present application not only can hold the fastening clip assembly in the use state by providing a locking arm on the leg of the insert that cooperates with the head of the clip, but also has a simple structure for realizing the cooperation between the locking arm and the clip and is easy to be detected. In addition, the cooperation between the locking arm of the fastening clip of the present application and the clip is firm and reliable.
