Description

Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to a fastening clip and a vehicle. Background Technology

[0002] In many applications, fasteners are used to secure two components, such as connecting layered components (e.g., carpets, headliners, or hood insulation) to a vehicle body panel. These fasteners typically consist of a cap, a post, and barbed tabs connected in sequence. When using fasteners to secure two components, both components have through holes. The end of the post furthest from the cap passes through these through holes. During insertion, the barbed tabs abut against the components, deforming and reducing their outer diameter to allow them to pass through the through holes. After exiting the through holes, the barbed tabs return to their original shape and engage with the components. This allows the cap and barbed tabs to clamp the two components on either side, thus securing them together.

[0003] Currently, fastening clips have poor resistance to mechanical impact and are not strong enough, resulting in poor reliability. Consequently, the connection of the fastening clips is not secure, and the fastening clips are prone to loosening or detaching from the components. Utility Model Content

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0046] The following combination Figures 1 to 6 The fastening buckle 100 and the vehicle provided in the embodiments of this application will be described in detail.

[0047] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the fastening buckle 100 provided in an exemplary embodiment of this disclosure. Figure 2 This is an internal cross-sectional view of the fastening buckle 100 provided in an exemplary embodiment of this disclosure. In a first aspect, embodiments of this application provide a fastening buckle 100. The fastening buckle 100 includes a cap 10, a column 20, and a spring arm 30. A groove 13 is provided on one side of the cap 10. One end of the column 20 extends into the groove and is connected to the cap 10. The spring arm 30 is connected to the column 20. At least a portion of the spring arm 30 protrudes radially from the column 20.

[0048] Specifically, the cap 10 protrudes outward from the middle of the side opposite to the column 20 to form a groove 13 on the other side.

[0049] It is understandable that the inner diameter of the groove 13 is larger than the outer diameter of the column 20, so that one end of the column 20 can extend into the groove 13.

[0050] It is understood that the elastic arm 30 and the cap 10 are spaced apart, and this space is used to clamp more than one component.

[0051] It is understood that when the elastic arm 30 is in its original state, at least part of the elastic arm 30 is located on one side of the radial direction of the column 20. When the elastic arm 30 is subjected to radially inward pressure, the elastic arm 30 moves closer to the axis of the column, and the outer diameter of the elastic arm 30 decreases.

[0052] The elastic arm 30 can be welded, glued, riveted, or integrally formed with the column 20. The cap 10 can be welded, glued, riveted, or integrally formed with the column 20.

[0053] Specifically, when the fastening buckle 100 secures the two components 50 together, each component 50 has a through hole 51. When the elastic arm 30 is in its original state, the maximum distance between the surface of the elastic arm 30 facing away from the axis of the column 20 and the axis of the column 20 is greater than the diameter of the through hole 51, while the distance between the end of the elastic arm 30 facing away from the axis of the column 20 and the axis of the column 20 is not greater than the diameter of the through hole 51. Compressing the elastic arm 30 towards the column 20 causes the elastic arm 30 to move closer to the axis of the column 20, thus ensuring that the maximum distance between the surface of the elastic arm 30 facing away from the axis of the column 20 and the axis of the column 20 is not greater than the diameter of the through hole 51.

[0054] Thus, when connecting the two components 50, the end of the column 20 facing away from the cap 10 passes through the two through holes 51 in sequence. As the column 20 passes through, the surface of the elastic arm 30 facing away from the column 20 abuts against the component 50. As the force of the squeezing and fastening buckle 100 increases, the elastic arm 30 deforms and moves closer to the axis of the column 20, so that the maximum distance between the surface of the elastic arm 30 facing away from the axis of the column 20 and the axis of the column 20 is not greater than the diameter of the through hole 51, thus allowing the elastic arm 30 to pass smoothly through the through hole 51. After the elastic arm 30 passes through the through hole 51, the elastic arm 30 returns to its original state. At this time, of the two components 50, the one closer to the cap 10 abuts against the cap 10, and the other abuts against the surface of the elastic arm 30 close to the cap 10. In this way, the two components 50 are fixedly connected by the fastening buckle. Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of the fastening buckle 100 that fixes two components 50 in an exemplary embodiment of this disclosure.

[0055] Compared to the flat caps in related technologies, in this embodiment, by protruding outward from the center of one side of the cap 10 to form a groove 13 on the other side, the cap 10 is made into an arched umbrella-shaped structure. This allows the external force on the cap 10 to be more dispersed, improving the structural strength of the cap 10 and increasing the load that the cap 10 can withstand. Thus, when the fastening buckle 100 is fixed to the relevant component, the anti-detachment holding force of the fastening buckle 100 is increased, making the holding force of the cap 10 on the relevant component more stable and reliable. Therefore, even if the cap 10 is subjected to large external forces (such as anti-detachment holding force, mechanical vibration force), it is not easily deformed, effectively preventing the fastening buckle 100 from falling off and improving the connection firmness of the fastening buckle 100.

[0056] Please see Figure 2 In some embodiments, the inner diameter of the groove 13 gradually decreases along the depth direction of the groove 13. This allows the side of the cap 10 near the opening of the groove 13 to transition more smoothly to the side of the cap 10 near the bottom of the groove 13, thereby improving the stress state of the cap 10, avoiding stress concentration, and thus improving the structural strength of the cap 10, thereby increasing the load that the cap 10 can withstand.

[0057] It can be understood that the depth direction of the groove 13 is from the end of the column 20 away from the cap 10 towards the end of the column 20 closer to the cap 10.

[0058] Please see Figure 2 In some embodiments, the cross-section of the groove 13 is circular. This improves the structural symmetry of the cap 10, thereby enhancing the uniformity of stress distribution on the cap 10 and increasing the load that the cap 10 can withstand.

[0059] Please see Figure 1 In some embodiments, at least a portion of the surface of the cap 10 facing away from the column 20 is convex as an arc surface, which is arranged around the axis of the column 20. This makes the structural change of the surface of the cap 10 facing away from the column smooth, so as to avoid stress concentration and thereby improve the structural strength of the cap 10, thereby increasing the load that the cap 10 can withstand.

[0060] In some embodiments, the cap 10 is formed by stamping sheet metal. This improves the forming efficiency of the cap 10.

[0061] It is understandable that the cap 10 is a part manufactured by stamping or other processes on a thin metal sheet. Using sheet metal to form the cap 10 can improve the processing performance of the cap 10 and give the cap better strength and rigidity.

[0062] In addition, sheet metal stamping parts have high dimensional accuracy after forming, and produce less waste during the production process, resulting in lower production costs.

[0063] Please see Figure 2 In some embodiments, the thickness of any two portions of the cap 10 is equal. This improves the structural uniformity of the cap 10, avoids stress concentration, and thus improves the structural strength of the cap 10, thereby increasing the load that the cap 10 can withstand.

[0064] Please see Figure 1 or Figure 2 In some embodiments, the fastening buckle 100 further includes a skirt 12. One end of the skirt 12 is connected to the edge of the cap 10, and the other end extends radially along the column 20. This prevents the burrs and sharp corners at the outer end of the cap 10 from scratching other components 50 during assembly, and also increases the contact area between the fastening buckle 100 and the component 50 when the fastening buckle 100 secures the component 50, so that the cap 10 is less prone to deformation and less likely to loosen when subjected to a large external force.

[0065] Please see Figure 1 or Figure 2 In some embodiments, the skirt 12 extends in a ring shape along the circumference of the cap 10. This improves the structural symmetry of the fastening buckle 100, thereby increasing the structural strength of the cap 10 and thus increasing the load that the cap 10 can withstand.

[0066] Please see Figure 1 or Figure 2 The skirt 12 is perpendicular to the axis of the column 20. This allows for a larger contact area between the skirt 12 and the component 50, thereby improving the uniformity of force distribution on the fastening buckle 100.

[0067] In some embodiments, the fastening buckle 100 is a metal component.

[0068] Specifically, the fastening buckle 100 is made of high-elasticity steel, and its working temperature range is -196℃ to 400℃.

[0069] In this embodiment, by setting the fastening buckle 100 to be a metal part, compared with the fastening buckle 100 made of plastic material, the fastening buckle 100 made of metal part has better high temperature resistance and low temperature resistance. In addition, the fastening buckle 100 made of metal part has high structural strength, high anti-loosening holding force, is not easy to deform or loosen, is reliable in fastening, and has good corrosion resistance and impact resistance.

[0070] In some embodiments, the column 20 is a hollow structure 22. This reduces the amount of material used in the column 20, thereby reducing its weight and consequently the weight of the fastening clip 100, which facilitates lightweight design of related devices using the fastening clip 100.

[0071] In some embodiments, the column 20 is formed by stamping and winding sheet metal. This improves the forming efficiency of the column 20, thereby reducing the manufacturing cost of the fastening clip 100.

[0072] In addition, sheet metal stamping parts have high dimensional accuracy after forming, and produce less waste during the production process, resulting in lower production costs.

[0073] Please see Figure 1 In some embodiments, the column 20 has a first mating edge 23 and a second mating edge 24 that are circumferentially connected. The first mating edge 23 and the second mating edge 24 are engaged. In this way, the first mating edge 23 and the second mating edge 24 can be fixed to each other to maintain the shape of the column 20, and the connection between the first mating edge 23 and the second mating edge 24 can be simple and easy to operate, thereby improving the forming efficiency of the column 20.

[0074] Please see Figure 1 In some embodiments, a dovetail groove 231 is provided on the first mating edge 23. A dovetail buckle 241 is provided on the second mating edge 24. The dovetail buckle 241 is located in the dovetail groove 231. The shape and size of the dovetail buckle 241 are consistent with the shape and size of the dovetail groove 231. In this way, the connection structure between the first mating edge 23 and the second mating edge 24 is a mortise and tenon structure, which makes the connection between the first mating edge 23 and the second mating edge 24 less prone to loosening or separation, thereby allowing it to withstand greater tensile force. This improves the reliability of the column 20 structure.

[0075] Please see Figure 2 In some embodiments, the elastic arm 30 is formed by bending the material area of ​​the stamped receiving groove 21 on a sheet metal part. In this way, the elastic arm 30 is integrally formed with the column 20, thereby reducing the number of parts connection points of the fastening buckle 100 and improving the structural stability of the fastening buckle 100, which in turn helps to improve the durability of the fastening buckle 100.

[0076] It is understandable that the receiving groove 21 is connected to the hollow structure 22.

[0077] It is understood that when the elastic arm 30 is in its original state, part of the elastic arm 30 is located on one side of the radial direction of the column 20, while the remaining elastic arms 30 can be located within the receiving groove 21. When the elastic arm 30 is subjected to radially inward pressure, the elastic arm 30 moves towards the receiving groove 21, and part of the elastic arm 30 can move into the hollow structure 22.

[0078] Please see Figure 2In some embodiments, the cap 10 is riveted or welded to the column 20. In this way, the cap 10 and the column 20 can be tightly connected by riveting or welding, so that the connection between the cap 10 and the column 20 can withstand greater external forces, thereby improving the structural stability of the fastening buckle 100.

[0079] Please see Figures 2 to 5 , Figure 4 This is a schematic diagram of the connection between the elastic arm and the column provided in an exemplary embodiment of this disclosure. Figure 5 This is a schematic diagram of the structure of the cap 10 provided in an exemplary embodiment of this disclosure. In some embodiments, a mating hole 11 is provided on the cap 10. A mating post 25 protrudes from the end of the post 20 facing the cap 10. The mating post 25 is inserted into the mating hole 11 and riveted or welded to the mating hole 11. In this way, the connection surface between the cap 10 and the post 20 is larger, which helps to improve the reliability of the connection between the cap 10 and the post 20.

[0080] Specifically, there are multiple mating holes 11, which are spaced apart circumferentially along the column 20. Correspondingly, there are multiple mating posts 25, which are spaced apart circumferentially along the column 20. Each of the multiple mating posts 25 mates with one of the multiple mating holes 11.

[0081] For example, there are five mating holes 11 and five mating posts 25, which are symmetrically distributed along the axis of the post 20.

[0082] Please see Figure 1 In some embodiments, a guide section 26 is provided at the end of the outer peripheral surface of the column 20 away from the cap 10. The outer diameter of the guide section 26 gradually decreases in the direction away from the cap 10. Thus, the guide section 26 guides the fastening clip 100 through the insertion hole, improving the assembly efficiency of the fastening clip 100. Specifically, when the fastening clip 100 connects two components 50, it first passes through the guide section 26 into the through hole 51 on the component 50, and then passes through the side of the column 20.

[0083] Please see Figure 1 or Figure 2 In some embodiments, along the direction away from the cap 10, the elastic arm 30 includes a first guide portion 31, a protrusion 32, and a second guide portion 33 connected in sequence. The distance between the side of the first guide portion 31 away from the axis of the column 20 and the axis of the column 20, and the distance between the side of the second guide portion 33 away from the axis of the column 20 and the axis of the column 20, both gradually decrease along the direction away from the protrusion 32. One of the first guide portion 31 and the second guide portion 33 is connected to the column 20. The protrusion 32 is spaced apart from the cap 10.

[0084] It is understood that when the elastic arm 30 is in its original state, at least a portion of the elastic arm 30 is located on one side of the radial direction of the column 20. When the elastic arm 30 is subjected to radially inward pressure, the distance between the protrusion 32 and the axis of the column 20 decreases.

[0085] For example, the elastic arm 30 is integrally formed with the column 20, and the end of the first guide portion 31 opposite to the protrusion 32 is connected to the column 20.

[0086] Specifically, the second guide portion 33 is connected to the column 20 at one end away from the protrusion 32.

[0087] It can be understood that by setting the distance between the side of the first guide portion 31 away from the axis of the column 20 and the axis of the column 20, and the distance between the side of the second guide portion 33 away from the axis of the column 20 and the axis of the column 20, both gradually decrease in the direction away from the protrusion 32, the surfaces of the first guide portion 31 and the second guide portion 33 away from the axis of the column 20 are inclined surfaces. Thus, when force is applied to the inclined surfaces of the first guide portion 31 and the second guide portion 33, the elastic arm 30 can deform towards the column 20, that is, the protrusion 32 can move closer to the axis of the column 20, thereby reducing the distance between the protrusion 32 and the axis of the column 20.

[0088] Specifically, the surface of the protrusion 32 facing away from the axis of the column 20 is an arc surface, which smoothly transitions to the surface of the first guide 31 facing away from the axis of the column 20 and the surface of the second guide 33 facing away from the axis of the column 20.

[0089] Specifically, when the fastening buckle 100 secures the two components 50 together, the two components 50 are provided with through holes 51. When the elastic arm 30 is in its original state, the maximum distance between the surface of the elastic arm 30 (i.e., the protrusion 32) facing away from the axis of the column 20 and the axis of the column 20 is greater than the diameter of the through hole 51. The distance between the surface of the first guide portion 31 facing away from the axis of the column 20 and the end near the cap 10 and the axis of the column 20, and the distance between the surface of the second guide portion 33 facing away from the axis of the column 20 and the end away from the cap 10 and the axis of the column 20, are both not greater than the diameter of the through hole 51. Compressing the elastic arm 30 towards the column 20 ensures that the maximum distance between the surface of the elastic arm 30 (i.e., the protrusion 32) facing away from the axis of the column 20 and the axis of the column 20 is not greater than the diameter of the through hole 51.

[0090] Thus, when connecting the two components 50, the end of the column 20 facing away from the cap 10 passes through the two through holes 51 in sequence. As the column 20 passes through, the surface of the second guide portion 33 facing away from the column 20 abuts against the component 50. As the force of the squeezing and fastening buckle 100 increases, the elastic arm 30 deforms, and the protrusion 32 moves closer to the axis of the column 20, so that the maximum distance between the surface of the protrusion 32 facing away from the axis of the column 20 and the axis of the column 20 is not greater than the diameter of the through hole 51, thereby allowing the elastic arm 30 to pass smoothly through the through hole 51. After the elastic arm 30 passes through the through hole 51, the elastic arm 30 returns to its original state. At this time, of the two components 50, the one closer to the cap 10 abuts against the cap 10, and the other abuts against the surface of the protrusion 32 near the cap 10. In this way, the two components 50 are fixedly connected by the fastening buckle 100. Figure 3 As shown.

[0091] When disassembling the two components 50, pull the cap 10 forcefully so that the inclined surface of the first guide portion 31 abuts against the component 50 until the elastic arm 30 deforms and the protrusion 32 moves closer to the axis of the column 20. The maximum distance between the surface of the protrusion 32 facing away from the axis of the column 20 and the axis of the column 20 is not greater than the diameter of the through hole 51, allowing the elastic arm 30 to pass smoothly through the through hole 51. In this way, the fastening buckle 100 can be removed from the component 50 to separate the two components 50.

[0092] In this embodiment, by providing a spring arm 30, and having the spring arm 30 including a first guide portion 31, a protrusion 32, and a second guide portion 33 connected sequentially in the direction away from the cap 10, when the fastening buckle 100 connects the two components 50, the second guide portion 33 guides the compression deformation of the spring arm 30 to achieve the installation of the fastening buckle 100; and during disassembly, the first guide portion 31 guides the compression deformation of the spring arm 30 to achieve the disassembly of the fastening buckle 100. This improves the detachability of the fastening buckle 100, thereby enhancing the convenience of maintenance.

[0093] Please see Figure 1 In some embodiments, the outer peripheral surface of the column 20 is provided with a receiving groove 21. The elastic arm 30 is configured to at least partially retract into the receiving groove 21 when subjected to radially inward compression along the column 20, and to at least partially protrude radially outward from the column 20 when the compression is removed. This provides space on the column 20 to accommodate the deformed elastic arm 30, thereby reducing the outer diameter of the elastic arm 30 and consequently reducing the radial dimension of the fastening clip 100. This allows the fastening clip 100 to be used in smaller installation scenarios, expanding its application range.

[0094] Please see Figure 1In some embodiments, there are multiple elastic arms 30, which are spaced apart circumferentially along the column 20.

[0095] Specifically, multiple elastic arms 30 are evenly distributed at intervals along the circumference of the column 20.

[0096] For example, there are three elastic arms 30.

[0097] Specifically, the multiple elastic arms 30 protrude radially along the column 20 with the same size, so that the protrusions 32 of each elastic arm 30 are on the same circumference.

[0098] The length of the elastic arm 30, the width and thickness of the spring piece, and the elastic modulus of the elastic arm 30 all affect the magnitude of the assembly and extraction force of the fastening clip 100. The total assembly elastic force of multiple spring pieces can be adjusted using mechanical simulation analysis software to ensure that the locking force of the fastening clip 100 in securing the relevant components 50 meets the requirements of the corresponding application. For example, if the required anti-detachment holding force for securing two pieces of material on certain vehicles is 75N, the fastening clip 100 can achieve an anti-detachment holding force of over 75N by adjusting the aforementioned parameters.

[0099] In this embodiment, by setting multiple elastic arms 30, on the one hand, the fastening buckle 100 can be subjected to uniform force, which helps to improve the force state of the fastening buckle 100; on the other hand, the anti-disengagement holding force of the fastening buckle 100 can be increased, thereby improving the stability of the fastening buckle 100 in locking the related components 50.

[0100] In some embodiments, a protective layer 40 is provided on the surface of at least one of the cap 10, the column 20, and the elastic arm 30. This effectively prevents the component 50 with the protective layer 40 from being scratched or corroded, improves the surface quality of the fastening clip 100, and thus enhances the durability of the fastening clip 100.

[0101] Specifically, the fastening buckle 100 is a metal component, and a protective layer 40 is provided on the surfaces of the cap 10, the column 20, and the elastic arm 30. The protective layer 40 is a zinc-nickel alloy layer. It can be understood that the zinc-nickel alloy layer can form a dense protective film on the metal surface, effectively blocking air, moisture, and other corrosive media from contacting the base metal, thereby slowing down the corrosion rate. In addition, the zinc-nickel alloy plating layer can present a uniform and bright surface, possessing good decorative properties. In some applications where appearance is highly important, it can also enhance the visual effect of the fastening buckle 100, meeting consumers' demands for product aesthetics.

[0102] When the fastening buckle 100 is a metal part, a zinc-nickel alloy layer is plated on the surface of the fastening buckle 100. Specifically, a protective layer 40 is electroplated on the outer surface of the fastening buckle 100.

[0103] Secondly, embodiments of this application provide a vehicle that includes the aforementioned fastening buckle 100.

[0104] Specifically, such as Figure 6 As shown, Figure 6 This is a schematic diagram of the structure of the fastening buckle 100 fixing the first plate 60 and the second plate 70 according to an exemplary embodiment of this disclosure. The vehicle includes the first plate 60 and the second plate 70. The first plate 60 is provided with a first through hole 61. The second plate 70 is provided with a second through hole 71. The first plate 60 and the second plate 70 are stacked, and the first through hole 61 and the second through hole 71 are arranged opposite to each other.

[0105] When connecting the first plate 60 and the second plate 70, the guide section 26 is first passed through the first through hole 61 and the second through hole 71. Guided by the guide section 26, the outer peripheral surface of the column 20, at the end of the protrusion 32 facing away from the cap 10, passes through the first through hole 61 and the second through hole 71 in sequence. As the column 20 is inserted, the surface of the second guide section 33 facing away from the column 20 abuts against the wall of the first through hole 61. As the force of the squeezing and fastening buckle 100 increases, the elastic arm 30 deforms, and the protrusion 32 moves closer to the axis of the column 20, so that the maximum outer diameter of the protrusion 32 is not greater than the diameter of the first through hole 61, thereby allowing the elastic arm 30 to pass smoothly through the first through hole 61 and enter the second through hole 71. Then, under the constraint of the wall of the second through hole 71, the elastic arm 30 continues to be in a deformed state until the protrusion 32 exits from the second through hole 71. After the protrusion 32 passes through the second through hole 71, the elastic arm 30 returns to its original state. At this time, both sides of the first plate 60 abut against the cap 10 and the second plate 70, respectively, and both sides of the second plate 70 abut against the surfaces of the first plate 60 and the protrusion 32 near the cap 10, respectively. In this way, the first plate 60 and the second plate 70 are fixedly connected by the fastening buckle 100.

[0106] It is understood that the outer diameter of the column 20 is not greater than the diameter of the first through hole 61 and the diameter of the second through hole 71. Optionally, the outer diameter of the column 20 is smaller than the diameter of the first through hole 61 and the diameter of the second through hole 71. The maximum outer diameter of the protrusion 32 is at least greater than the diameter of the second through hole 71. The outer diameter of the cap 10 is at least greater than the diameter of the first through hole 61.

[0107] The anti-detachment holding force of the fastening buckle 100 can be adjusted according to the installation scenario. For example, if an anti-detachment holding force of 75N is required, the length of the elastic arm 30, the width of the spring piece, the thickness of the spring piece, and the elastic modulus of the elastic arm 30 can be adjusted to ensure that the anti-detachment holding force of the fastening buckle 100 is not less than 75N.

[0108] It is understood that the vehicle may be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this disclosure does not make any specific restrictions.

[0109] It is understood that the vehicle includes the aforementioned fastening clip 100. The vehicle has all the beneficial effects of the aforementioned fastening clip 100, which will not be repeated here.
