Description

Technical Field

[0001] This utility model belongs to the technical field of connectors, and in particular relates to a metal clip and connecting assembly. Background Technology

[0002] In the lightweight design of new energy vehicles, the assembly connection between sheet metal parts and plastic substrates usually relies on metal clips as transition parts to ensure structural stability and assembly efficiency.

[0003] Currently, there are many styles of metal clips on the market, but most of them use a clamping structure to connect and fix them to sheet metal parts. Due to the structural design limitations of these metal clips, they often have insufficient pull-out force when clamping sheet metal parts. This not only reduces the reliability of the connection, but may also affect the assembly stability of sheet metal parts on plastic substrates, making it difficult to meet the stringent requirements of new energy vehicles for high stability of structural components. Utility Model Content

[0004] In view of this, it is necessary to provide a metal clip and connecting assembly for solving the above-mentioned technical problems.

[0005] A metal clip is embedded in a plastic substrate to limit and retain a sheet metal part inserted into the metal clip, thereby connecting the sheet metal part to the plastic substrate. The metal clip includes a connecting piece and two clip bodies. The two clip bodies are symmetrically arranged on both sides of the connecting piece and are respectively connected to the connecting piece as a whole. Furthermore, the two clip bodies and the connecting piece together form a clamping cavity, which allows the sheet metal part to be inserted.

[0006] The clip body includes a main body, a first clip, and a second clip. The first clip is disposed at the top of the main body at an angle. One end of the first clip extending out of the clamping cavity is used to abut and limit the plastic substrate, and the other end of the first clip is used to abut and limit the sheet metal part inserted into the metal clip. The second clip is disposed at the location of the main body and is used to abut and limit the sheet metal part inserted into the metal clip.

[0007] The damping force provided by the two clamping bodies when the sheet metal part is inserted into the clamping cavity is set to F1, where F1≤60N; and the pull-out resistance force of the two clamping bodies when clamping the sheet metal part is set to F2, where F2≥200N.

[0008] Understandably, the two clamping bodies use symmetrical first and second clamps to hold the sheet metal parts, and the pull-out force of the metal clamps when holding the sheet metal parts is set to be greater than 200N. This allows the metal clamps to provide the sheet metal parts with a sufficiently large pull-out force when connecting the plastic substrate and the sheet metal parts, thereby improving the reliability of the metal clamps in connecting the sheet metal parts to the plastic substrate, so as to meet the stringent requirements of new energy vehicles for high stability of structural components.

[0009] In one embodiment, the first clip is deformed under pressure so that the thickness of the first clip is less than the thickness of the main body piece;

[0010] And / or, the second clip is deformed under pressure so that the thickness of the second clip is less than the thickness of the main body piece.

[0011] It is understandable that flattening the first and / or second clips can improve their structural strength, thereby increasing their resistance to pull-out when holding sheet metal parts. This allows the metal clip to be manufactured and improved based on the existing structure, avoiding redesign and reducing costs.

[0012] In one embodiment, the first clip includes a first main body and two first clamping parts. The two first clamping parts are disposed at both ends of the first main body in the length direction of the clamping cavity and are spaced apart from the main body piece, respectively for abutting and limiting the sheet metal parts inserted into the metal clip.

[0013] The first main body portion transitions to and connects with the main body piece via an arc, and is positioned upwards to abut and limit contact with the plastic substrate.

[0014] In one embodiment, the first main body has two arc-shaped grooves, and the two arc-shaped grooves correspond one-to-one with the two first clamping parts;

[0015] The arc-shaped groove is disposed between the corresponding first clamping part and the main body piece, and the first main body part and the corresponding main body piece can be connected and transitioned through the groove wall of the arc-shaped groove.

[0016] In one embodiment, the second clip includes a second main body and two second clamping parts. The two second clamping parts are disposed at one end of the second main body in the depth direction of the clamping cavity, and are respectively used to abut and limit the sheet metal parts inserted into the metal clip.

[0017] The second main body is disposed in the area where the groove is located on the main body piece and is connected to the main body piece, for contacting and limiting the plastic substrate.

[0018] In one embodiment, the two second clamping portions are connected by an arc transition.

[0019] In one embodiment, the main body sheet is provided with reinforcing ribs that extend along the depth direction of the clamping cavity.

[0020] Understandably, by setting reinforcing ribs on the main body, the structural strength of the main body can be enhanced, preventing the main body from breaking under stress when the metal clip connects the plastic substrate and the sheet metal part. In this way, the reliability of the metal clip connecting the sheet metal part to the plastic substrate can be further improved.

[0021] In one embodiment, the number of reinforcing ribs is configured as two, and the two reinforcing ribs are arranged on both sides of the main body piece along the length direction of the clamping cavity.

[0022] In one embodiment, the main body portion protrudes in a direction away from the clamping cavity and is formed with the reinforcing rib.

[0023] Understandably, the above structural design facilitates the fabrication of reinforcing ribs on the main body sheet, while also preventing the reinforcing ribs from affecting the clamping of the sheet metal parts by the metal clip.

[0024] In addition, this application also provides a connecting component, including a plastic substrate, a sheet metal part, and the metal clips described above;

[0025] The metal clip is embedded in the plastic substrate and abuts against and limits the position of the sheet metal part.

[0026] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0027] The metal clip and connecting assembly claimed in this application use two symmetrical first and second clips to hold sheet metal parts, and the pull-out force of the metal clips when holding the sheet metal parts is set to be greater than 200N. This allows the metal clips to provide sufficiently large pull-out force to the sheet metal parts when connecting the plastic substrate and the sheet metal parts, thereby improving the reliability of the connection between the metal clips and the sheet metal parts on the plastic substrate, so as to meet the stringent requirements of high stability of structural components in new energy vehicles.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] like Figure 3As shown, the metal clip 100 claimed in this application is used in new energy vehicles to fix sheet metal parts 200 to plastic substrates 300. Specifically, the metal clip 100 is embedded in the plastic substrate 300, and the sheet metal parts 200 are inserted into the metal clip 100. The assembly and positioning of the sheet metal parts 200 within the plastic substrate 300 are achieved by using the contact and limiting between the metal clip 100 and the plastic substrate 300 and the sheet metal parts 200 respectively.

[0037] like Figure 1 , Figure 2 As shown, the metal clip 100 provided in this application includes a connecting piece 10 and two clip bodies 20. The two clip bodies 20 are symmetrically disposed on both sides of the connecting piece 10 and are respectively connected to the connecting piece 10 as a whole. The two clip bodies 20 and the connecting piece 10 together form a clamping cavity 101, which allows the sheet metal part to be inserted. The clip body 20 includes a main body 21, a first clip 22 and a second clip 23. The first clip 22 is disposed at the top of the main body 21 in an inclined manner, and the clamping cavity 101 extends out of the first clip 22. One end of the first clip 21 is used to abut and limit the sheet metal part 200 inserted into the metal clip 100; the other end of the first clip 22 is used to abut and limit the sheet metal part 200 inserted into the metal clip 100; the second clip 23 is located at the position of the main body piece 21 and is used to abut and limit the sheet metal part 200 inserted into the metal clip 100; the damping force provided by the two clip bodies 20 when the sheet metal part 200 is inserted into the clamping cavity 101 is set to F1, F1≤60N; and the pull-out resistance force when the two clip bodies 20 clamp the sheet metal part 200 is set to F2, F2≥200N. Here, both the first clip 22 and the second clip 23 can abut the sheet metal part 200 obliquely downward to achieve the abutment and limitation of the sheet metal part 200 on the metal clip 100. In some embodiments, F1 can be 50N, 55N, or 60N; F2 can be 200N, 210N, or 220N.

[0038] As can be seen from the above, in the metal clip 100 of this application, the two clip bodies 20 use a symmetrical first clip 22 and a second clip 23 to clamp the sheet metal part 200, and the pull-out force of the metal clip 100 when clamping the sheet metal part 200 is set to be greater than 200N, so that when the metal clip 100 connects the plastic substrate 300 and the sheet metal part 200, it can provide the sheet metal part 200 with a sufficiently large pull-out force, thereby improving the reliability of the connection of the metal clip 100 to the sheet metal part 200 on the plastic substrate 300, so as to meet the stringent requirements of new energy vehicles for high stability of structural components.

[0039] like Figure 1 , Figure 2As shown, in one embodiment, the first clip 22 is deformed under pressure so that its thickness is less than the thickness of the main body piece 21; and / or, the second clip 23 is deformed under pressure so that its thickness is less than the thickness of the main body piece 21. That is, this embodiment can improve the structural strength of the corresponding first clip 22 and / or second clip 23 by flattening the first clip 22 and / or the second clip 23, thereby increasing the pull-out resistance when the metal clip 100 holds the sheet metal part 200. This allows the metal clip 100 to be obtained through processing improvements based on the original structure, avoiding redesign and reducing costs. Here, both the first clip 22 and the second clip 23 are manufactured through a flattening process.

[0040] like Figure 1 As shown, in this embodiment, the first clip 22 includes a first main body 221 and two first clamping parts 222. The two first clamping parts 222 are disposed at both ends of the first main body 221 along the length of the clamping cavity 101 and spaced apart from the main body piece 21, respectively for abutting and limiting the sheet metal part 200 inserted into the metal clip 100. The first main body 221 and the main body piece 21 are connected by an arc transition and are positioned upwards to abut and limit the plastic substrate 300. In other words, the first clip 22 in this embodiment utilizes the arc transition between the first main body 221 and the main body piece 21 to effectively disperse the force between them, thereby improving the stability of the connection between the first clip 22 and the main body piece 21.

[0041] like Figure 1 As shown, in this embodiment, the first main body 221 has two arc-shaped grooves 2211, which correspond one-to-one with the two first clamping parts 222. The arc-shaped grooves 2211 are located between the corresponding first clamping part 222 and the main body piece 21, and the main body piece 21 and the corresponding first clamping part 222 can be connected and transitioned through the groove wall 22111 of the arc-shaped groove 2211. That is to say, in this embodiment, the first clamping part 222 and the main body piece 21 can also transmit force through the groove wall 22111 of the arc-shaped groove 2211. This can effectively disperse the force between the first clamping part 222 and the main body piece 21, thereby improving the stability of the force between the first clamp 22 and the main body piece 21 when the first clamping part 222 abuts against the limiting sheet metal part 200.

[0042] like Figure 1As shown, in one embodiment, the second clip 23 includes a second main body 231 and two second clamping parts 232. The two second clamping parts 232 are disposed at one end of the second main body 231 in the depth direction of the clamping cavity 101, and are respectively used to abut and limit the sheet metal part 200 inserted into the metal clip 100. Here, the second main body 231 is disposed in the area where the slot 211 is located on the main body piece 21 and is connected to the main body piece 21, and abuts and limits the plastic substrate 300. That is to say, the second clip 23 of this embodiment can use the two second clamping parts 232 to abut and limit the sheet metal part 200 inserted into the clamping cavity 101.

[0043] like Figure 1 As shown, in this embodiment, the two second clamping portions 232 are connected by an arc. This allows the connection between the second clamping portion 232 and the second main body portion 231 to be effectively dispersed after being subjected to force, thereby improving the stability of the connection between the second clamping portion 232 and the second main body portion 231.

[0044] like Figure 1 , Figure 2 As shown, in one embodiment, a reinforcing rib 212 is formed on the main body 21, and the reinforcing rib 212 extends along the depth direction of the clamping cavity 101. This embodiment can use the reinforcing rib 212 to enhance the structural strength of the main body 21, preventing the main body 21 from breaking under stress when the metal clip 100 connects the plastic substrate 300 and the sheet metal part 200. In this way, the reliability of the connection between the metal clip 100 and the sheet metal part 200 on the plastic substrate 300 can be further improved.

[0045] like Figure 1 , Figure 2 As shown, in this embodiment, the number of reinforcing ribs 212 is configured as two, and the two reinforcing ribs 212 are arranged on both sides of the main body piece 21 along the length direction of the clamping cavity 101. Here, the main body piece 21 partially protrudes away from the clamping cavity 101 and forms the reinforcing ribs 212. This facilitates the processing and forming of the reinforcing ribs 212 on the main body piece 21, and also avoids the setting of the reinforcing ribs 212 affecting the clamping of the sheet metal part 200 by the metal clip 100.

[0046] like Figure 3 As shown, this application also provides a connecting component, including a plastic substrate 300, a sheet metal part 200, and the aforementioned metal clip 100; the metal clip 100 is embedded in the plastic substrate 300 and abuts against and limits the sheet metal part 200.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
