[0023] The following will describe various specific implementation manners of the present application with reference to the accompanying drawings that form a part of this specification. It should be understood that although terms indicating directions, such as "front", "rear", "upper", "lower", "left", "right", etc., are used in the present application to describe various exemplary structural parts and elements of the present application, these terms are used herein only for the purpose of convenient description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present application can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations.

[0024] Figure 1A is a perspective view of the fastening clip of the first embodiment of the present application, Figure 1B is Figure 1A a perspective view of another angle of the fastening clip in. As Figure 1A and Figure 1B shown, the fastening clip 100 includes a base plate 101, a support portion 102, a pair of first extension portions 121 and 122, a pair of second extension portions 123 and 124, a pair of holding arms 131 and 132, and a pair of connection and cooperation portions 141 and 142. The fastening clip 100 is integrally formed from a thermoplastic material. The fastening clip 100 has a length direction L1, a width direction W1, and a height direction H1. The fastening clip can connect the first component and the second component, wherein the connection and cooperation portions 141 and 142 cooperate with the second extension portions 123 and 124 to connect the first component, and the holding arms 131 and 132 cooperate with the first extension portions 121 and 122 to connect the second component.

[0025] The substrate 101 is generally a rectangular flat plate with a certain thickness, and has an upper surface 111, a lower surface 112, a pair of first side portions 151 and 152 that extend along the length direction L1 and are oppositely arranged, and a pair of second side portions 153 and 154 that extend along the width direction W1 and are oppositely arranged. The support portion 102 is generally plate-shaped and extends from the upper surface 111 of the substrate 101 along the length direction L1 and the height direction H1 of the fastening clip 100. The connection portion between the support portion 102 and the substrate 101 is generally located at the middle position in the width direction of the substrate 101. A pair of holding arms 131 and 132 are respectively connected to the distal end 140 of the support portion 102, and extend from the distal end 140 of the support portion 102 toward the substrate 101 and outwardly, so that there is a spacing between the pair of holding arms 131 and 132 and the support portion 102 respectively. The first extension portions 121 and 122 are respectively connected to the first side portions 151 and 152 of the substrate 101, and the second extension portions 123 and 124 are respectively connected to the second side portions 153 and 154 of the substrate 101. The connection and cooperation portions 141 and 142 are connected to the lower surface 112 of the substrate 101 and are respectively close to the second side portions 153 and 154.

[0026] In this application, both the first extension portions 121 and 122 and the second extension portions 123 and 124 have a certain elasticity, so that the fastening clip can adapt to first components and second components with different thicknesses.

[0027] The fastening clip 100 further includes a positioning convex portion 165, and the positioning convex portion 165 is connected to the lower surface 112 of the substrate 101 and is located at the center of the substrate 101.

[0028] Figure 2 is Figure 1A a front view of the fastening clip in Figure 3 is Figure 1A a side view of the fastening clip in. Combined with Figures 1A to 3As shown, the second extension parts 123 and 124 have a symmetric structure, and the connection and cooperation parts 141 and 142 have a symmetric structure. The second extension part 123 includes an inclined extension from the second side part 153 of the substrate 101 in a direction away from the center and the upper surface 111 of the substrate 101, that is, extending outward and downward. The distal end of the second extension part 123 has a contact part 231 facing the connection and cooperation part 141, and the contact part 231 includes a plane substantially parallel to the substrate 101. The connection and cooperation part 141 includes a vertical part 241 and a horizontal part 242. The vertical part 241 extends downward from the lower surface 112 of the substrate 101, and the horizontal part 242 extends outward from the distal end 246 of the vertical part 241 along a direction substantially parallel to the substrate 101, so that the horizontal part 242 is located below the second extension part 123 and has a spacing from the second extension part 123. A groove 251 is formed among the second extension part 123, the vertical part 241 and the horizontal part 242. On the length direction L1 of the fastening clip 100, one side of the groove 251 away from the center of the substrate 101 has a first opening 261. The second extension part 123 extends obliquely from the proximal end to the distal end towards the horizontal part 242, so that in the length direction of the fastening clip, the thickness of the groove gradually decreases from the vertical part 241 to the first opening 261. On the width direction W1 of the fastening clip 100, both ends of the groove 251 respectively have a second opening 262 and a third opening 263. The first component can be loaded into the groove 251 from the second opening 262 or the third opening 263. On the width direction W1 of the fastening clip 100, the middle section of the groove 251 has a uniform thickness, and at both ends close to the openings 262 and 263, the thickness of the groove 251 gradually increases to form a trumpet shape to guide the first component into the groove 251. A limiting part 271 is arranged in the groove 251. The limiting part 271 is connected with the vertical part 241 and the horizontal part 242 and has a spacing from the second extension part 123. In an embodiment of the present application, on the width direction W1 of the fastening clip 100, the limiting part 271 is located in the middle section of the groove 251 and has a spacing from the openings 262 and 263.

[0029] Similarly, the second extension portion 124 includes an inclined extension from the second side portion 154 of the substrate 101 in a direction away from the center of the substrate 101 and the upper surface 111, that is, extending outward and downward. The distal end of the second extension portion 124 has a contact portion 232, and the contact portion 232 includes a plane substantially parallel to the substrate 101. The connection and mating portion 142 includes a vertical portion 243 and a horizontal portion 244. The vertical portion 243 extends downward from the lower surface 112 of the substrate 101, and the horizontal portion 244 extends outward from the distal end 247 of the vertical portion 243 along a direction substantially parallel to the substrate 101. Thus, the horizontal portion 244 is located below the second extension portion 124 and has a spacing from the second extension portion 124. A groove 252 is defined among the second extension portion 124, the vertical portion 243, and the horizontal portion 244. On the length direction L1 of the fastening clip 100, one side of the groove 252 away from the center of the substrate 101 has a first opening 265. The second extension portion 124 extends obliquely from the proximal end to the distal end toward the horizontal portion 244. Thus, in the length direction of the fastening clip, the thickness of the groove gradually decreases from the vertical portion 243 to the first opening 265. On the width direction W1 of the fastening clip 100, both ends of the groove 252 respectively have a second opening 267 and a third opening 268. The first component can be loaded into the groove 252 from the second opening 267 or the third opening 268. On the width direction W1 of the fastening clip 100, the middle section of the groove 252 has a uniform thickness. At both ends close to the openings 267 and 268, the thickness of the groove 252 gradually increases to form a flared shape to guide the first component into the groove 252. A limiting portion 272 is provided in the groove 252. The limiting portion 272 is connected to the vertical portion 243 and the horizontal portion 244 and has a spacing from the second extension portion 124. In an embodiment of the present application, on the width direction W1 of the fastening clip 100, the limiting portion 272 is located in the middle section of the groove 252 and has a spacing from the openings 267 and 268.

[0030] In the present application, the second extension portions 123 and 124 and the connection and mating portions 141 and 142 extend a certain distance in the length direction of the fastener. In an embodiment of the present application, in the length direction of the fastener, the lengths of the second extension portions 123 and 124 and the lengths of the connection and mating portions 141 and 142 are not less than 1 / 5 of the length of the substrate 101. In an embodiment of the present application, in the length direction of the fastener, the lengths of the second extension portions 123 and 124 and the lengths of the connection and mating portions 141 and 142 are not less than 1 / 4 of the length of the substrate 101. The second extension portions 123 and 124 are elastic, so that the thicknesses of the grooves 251 and 252 can change and can adapt to first components of different thicknesses. The lengths of the second extension portions 123 and 124 in the fastener endow them with good elasticity.

[0031] Combined Figures 1A to 3As shown, a pair of holding arms 131 and 132 extend downwardly and obliquely from the distal end of the support portion 102 respectively, so as to have a spacing from the support portion 102 and be able to deflect towards the support portion 102. The pair of holding arms 131 and 132 have the same structure and are symmetrically arranged with respect to the support portion 102. The pair of holding arms 131 and 132 include bases 305 and 306 and abutting portions 315 and 316. The bases 305 and 306 extend from the distal end of the support portion 102, and an included angle is formed between the extending directions of the inner surfaces of the bases 305 and 306 and the support portion 102. The upper ends (i.e., free ends) of the pair of holding arms 131 and 132 form the abutting portions 315 and 316. The abutting portions 315 and 316 are used to contact the second component to be connected. The extending directions of the inner surfaces of the abutting portions 315 and 316 are substantially parallel to the support portion 102. Steps 325 and 326 are respectively provided on the outer sides of the abutting portions 315 and 316, and the steps 325 and 326 respectively include multiple levels of steps. In an embodiment of the present application, the number of levels of steps is four, and in other embodiments, the number of steps may be other numbers. Each level of step includes a step surface 329 facing the substrate 101, and between adjacent steps, the step surface closer to the inner side is closer to the substrate 101. That is to say, each level of step surface of each of the abutting portions 315 and 316 gradually moves away from the substrate 101 from the inner side to the outer side of the corresponding abutting portion. Each step surface extends obliquely in a direction away from the substrate 101 from the inside to the outside, so as to form an included angle with the extending direction of the substrate 101, and the number of angles of the included angle is not greater than 30°.

[0032] The first extension portions 121 and 122 extend obliquely in a direction away from the lower surface 112 of the substrate 101, that is, extend obliquely in the direction of the abutting portions 315 and 316. The distal ends of the first extension portions 121 and 122 have contact portions 343 and 344, the contact portions 343 and 344 face the abutting portions 315 and 316, and the contact portions 343 and 344 are substantially planar, and their extending directions are substantially parallel to the extending direction of the substrate 101. The first extension portions 121 and 122 have elasticity, and the first extension portions 121 and 122 cooperate with the steps of the abutting portions 315 and 316 to be able to clamp the second component between the step surfaces of the abutting portions 315 and 316 and the contact portions of the first extension portions 121 and 122. The step surfaces of different heights are applicable to second components of different thicknesses, and the elasticity of the first extension portions 121 and 122 can cooperate with the step surfaces to press the second component tightly.

[0033] Combine Figures 1A to 3As shown, the support portion 102 has an upper part 211, a middle part 212, and a lower part 213 that are connected in sequence. The lower part 213 is connected to the upper surface 111 of the substrate 101. And in the length direction L1 of the fastening clip 100, the length of the lower part 213 is substantially the same as the length of the substrate 101, that is, the outer side of the lower part 213 is flush with the outer side of the substrate 101. The length of the middle part 212 gradually decreases from bottom to top, so that a pair of middle inclined surfaces 223, 224 that incline downward and inward are formed on both sides of the middle part 212. The length of the upper part 213 also gradually decreases from bottom to top, so that a pair of upper inclined surfaces 225, 226 that incline downward and inward are formed on both sides of the upper part 213. The inclination angles of the upper inclined surfaces 225, 226 with respect to the substrate 101 are greater than the inclination angles of the middle inclined surfaces 223, 224 with respect to the substrate 101. That is, with respect to the substrate 101, the upper inclined surfaces 225, 226 are steeper than the middle inclined surfaces 223, 224. The distal end 140 of the upper part 211 is connected to a pair of holding arms 131 and 132. The length of the distal end of the upper part 211 is the same as the width of the pair of holding arms 131, 132 in the length direction of the substrate 101. The settings of the middle inclined surfaces 223, 224 and the upper inclined surfaces 225, 226 can save materials for the support portion 102 while ensuring the strength of the support portion 102, and reduce the total weight of the fastening clip 100.

[0034] Figure 4 FIG. is an exploded view of the fastening clip 100, the first component, and the second component in the present application, showing the structures of the fastening clip 100 and the two components connected thereto.

[0035] As Figure 4 shown, the fastening clip 100 can connect the first component 401 and the second component 402. The first component 401 includes a base 411, a pair of connecting claws 412 and 413, and a positioning recess 415. The distal ends of the pair of connecting claws 412 and 413 include engaging portions 425 and 426 that extend toward each other. The second component 402 has a square mounting hole 440. When connecting, the fastening clip 100 is first connected to the first component 401, and then the fastening clip 100 connected to the first component is connected to the second component 402, so that the first component 401 and the second component 402 are connected.

[0036] In an embodiment of the present application, the first component 401 is the ceiling of a vehicle, and the second component 402 is the sheet metal of the vehicle.

[0037] Figure 5A FIG. is a side view of the connection between the first component and the second component and the fastening clip. Figure 5B is Figure 5A a cross-sectional view of Figure 6A FIG. is a side view of the connection between the first component and the second component and the fastening clip from another angle. Figure 6B isFigure 6A A sectional view.

[0038] When it is necessary to connect the fastening clip 100 to the first component 401, place the fastening clip 100 on one side of the first component 401 so that, in the horizontal direction, the latching portions 425 and 426 are aligned with the grooves 251 and 252 of the fastening clip 100. Then, push the fastening clip 100 towards the first component 401 along the width direction W1 of the fastening clip 100, so that the latching portions 425 and 426 enter the grooves 251 and 252 of the fastening clip 100, and the fastening clip 100 is connected to the first component 401.

[0039] The second extension portions 123 and 124 have a certain elasticity. During the process of the latching portions 425 and 426 entering the grooves 251 and 252, the second extension portions 123 and 124 can deform, increasing the thickness of the grooves 251 and 252, so that the latching portions 425 and 426 are clamped between the second extension portions 123 and 124 and the horizontal portions 242 and 244 of the connection and cooperation portion.

[0040] In different application scenarios, there may be a difference in the thickness of the latching portions 425 and 426, and the elasticity of the second extension portions 123 and 124 can adapt to the thickness of different latching portions.

[0041] When the fastening clip 100 enters the first component 401, the positioning convex portion 165 is deformed by the extrusion of the edge of the positioning concave portion 415, so that the positioning convex portion 165 can enter the positioning concave portion 415. When the fastening clip 100 is installed in the first component 401 and in place, the positioning convex portion 165 is limited in the positioning concave portion 415, making it difficult for the fastening clip 100 to fall off the first component 401 in the width direction of the fastening clip. The limiting portions 271 and 272 of the fastening clip 100 respectively abut against the edges of the latching portions 425 and 426, making it difficult for the fastening clip 100 to fall off the first component 401 in the length direction of the fastening clip.

[0042] The mounting holes 440 of the second component can be slots or holes extending along the length direction of the substrate 101. The mounting holes 440 have a pair of oppositely arranged inner edges 427 and 428. When the fastening clip 100 is inserted downward into the second component 402, the outer sides of a pair of retaining arms 131 and 132 are respectively oriented towards the inner edges 427 and 428, so that the retaining arms 131 and 132 enter the mounting holes 440. When the fastening clip 100 moves until the outer sides of the retaining arms 131 and 132 contact the inner edges 427 and 428, and the operator continues to apply pressure to the fastening clip 100, the retaining arms 131 and 132 will be pressured by the inner edges 427 and 428 and contract inward, so that the retaining arms 131 and 132 can continue to move downward. Until the first extension parts 121 and 122 of the fastening clip 100 contact the surface of the second component 402, at this time, the fastening clip 100 is subject to the resistance from the first extension parts 121 and 122. Continuing to apply appropriate pressure to the fastening clip 100, the first extension parts 121 and 122 are deformed, and one step surface in the step parts of the retaining arms 131 and 132 abuts against the substrate 101 near the inner edges 427 and 428. After the pressure applied to the fastening clip 100 is withdrawn, the fastening clip 100 is installed in place. At this time, the second component 402 is clamped between the first extension parts 121 and 122 and the step surfaces of the retaining arms 131 and 132, and the fastening clip 100 is connected to the second component 402.

[0043] In the present application, the fastening clip 100 has multiple levels of steps, and the first extension parts 121 and 122 are elastic and can adapt to second components 402 of different thicknesses.

[0044] The fastening clip 100 in the present application has a pair of first extension parts, a pair of second extension parts, and a pair of elastic arms including step parts. The first extension parts and the pair of second extension parts can adapt to first components and second components of different thicknesses to match different user requirements.
